Patent Description:
For example, in a vehicle-body front portion of an automobile which is disclosed in Patent Literature <NUM>, a pair of left and right front side frames extending in a vehicle front-rear direction are provided, and a front sub-frame is provided below those front side frames and in rear of an engine room. In a left-side front end portion and a right-side front end portion of the front sub-frame, a left pipe frame and a right pipe frame are respectively provided to extend toward vehicle front. The left pipe frame and the right pipe frame are inclined with respect to a center line extending in a front-rear direction of a vehicle so as to be positioned on vehicle-width-direction outer sides toward a front side.

Patent Literature <NUM> discloses that the left pipe frame and the right pipe frame are inclined to be positioned on the vehicle-width-direction outer sides toward the front side and an impact load can thereby properly be absorbed in a case of an offset collision in which the impact load is input from oblique front of the vehicle.

Document <CIT> shows a cross member disposed at the vehicle front portion. The cross member is placed further toward a vehicle front side than the non-contact charger, whereby it is extending in a vehicle transverse direction. The bottom surface of the cross member is disposed further toward a vehicle lower side than the bottom surface of the non-contact charger.

Incidentally, in an electric vehicle, batteries with large capacities for supplying electric power to a traveling motor are installed. It is possible that in order to improve convenience in charging the batteries, a contactless charger is provided. Because in a case of an automobile, charging is presumed to be performed when the automobile stands still, it is necessary to place a power transmission coil in an area below the automobile which stands still (such as a ground surface of a parking lot or a floor surface of a garage, for example) and to set a position for disposing the contactless charger in the vehicle such that the contactless charger is arranged directly above the power transmission coil.

Incidentally, because batteries are often disposed below a floor panel of a vehicle, when the contactless charger is disposed below the floor panel, how to secure a minimum ground clearance becomes a problem. Further, it is possible to dispose the contactless charger below a vehicle-body rear portion, but because the contactless charger includes a large-sized coil which is capable of receiving a large current, each of a thickness dimension of the contactless charger and a dimension in a vehicle front-rear direction becomes long, and as a result, how to secure a departure angle becomes a problem.

The present invention has been made in consideration of such problems, and an object thereof is to improve layout characteristics of a contactless charger while sufficiently securing impact absorbability in an offset collision.

To achieve the above object, a first aspect of the present invention can be based on a vehicle-body front structure for an electric vehicle which includes a traveling motor and in which a battery casing housing a battery supplying electric power to the traveling motor is disposed below a floor panel. The vehicle-body front structure includes: a front-side battery frame which is provided in a front portion of the battery casing; a pair of left and right side frames which extend from the front-side battery frame toward vehicle front; a contactless charger which is arranged between the left and right side frames and receives a charging current for the battery from an outside; and a first cross member which is suspended between a portion in the left side frame, the portion being spaced apart from the front-side battery frame to the vehicle front, and a portion in the right side frame, the portion being spaced apart from the front-side battery frame to the vehicle front. The contactless charger has a cross member arrangement portion in which the first cross member is capable of being arranged.

In this configuration, in a case where a left side offset collision is presumed in which an impact load is input from obliquely left front, for example, because the left side frame extends so as to correspond to an input direction of the impact load, the impact load from the obliquely left front is input generally along an axis direction of the left side frame, and the impact load is absorbed by the left side frame. In addition, the impact load input to the left side frame is transmitted to the front-side battery frame and is thus also absorbed by the front-side battery frame. In this case, because the left and right side frames are in a state where those are coupled together by the first cross member, the left side frame is less likely to collapse but is more likely to be axially compressed. The same applies to a right side offset collision.

Because the left and right side frames are positioned on the vehicle-width-direction outer sides toward the front, a wide space in a vehicle width direction is formed between both of the side frames, that is, on a lower side of a vehicle-body front portion. By arranging the contactless charger in the space, how to secure a minimum ground clearance does not become a problem, and how to secure a departure angle does not become a problem either. Furthermore, a large-sized coil can be housed in the contactless charger, and it becomes possible to receive a large current in charging.

Further, an intermediate portion of the first cross member in the vehicle width direction is also arranged in the space, but because the intermediate portion of the first cross member in the vehicle width direction is arranged in the cross member arrangement portion of the contactless charger, layout characteristics of the contactless charger are improved.

The first cross member according to a second aspect of the present invention may have an intermediate member portion which is positioned in an intermediate portion in a vehicle width direction and is arranged in the cross member arrangement portion and outside member portions which extend from both end portions of the intermediate member portion in the vehicle width direction toward vehicle-width-direction outer sides and are coupled with the left and right side frames.

In a third aspect of the present invention, a second cross member which is suspended between the left and right side frames may be provided in vehicle rear of the contactless charger.

In this configuration, in a case where an impact load is input from front, because the second cross member is positioned in the rear of the contactless charger, the contactless charger can be deformed or destroyed in front of the second cross member. Accordingly, it becomes possible to absorb an impact by using the contactless charger.

In a fourth aspect of the present invention , the cross member arrangement portion of the contactless charger is configured with a recess portion which is capable of housing the first cross member. In this configuration, the contactless charger may be attached such that the first cross member is housed in the recess portion of the contactless charger when the vehicle is manufactured, for example, and attachment workability becomes high.

The recess portion according to a fifth aspect of the present invention may have a shape which is open in a lower surface of the contactless charger.

In a sixth aspect of the present invention, the vehicle-body front structure may include a pair of left and right impact absorption members which extend toward vehicle front of the first cross member. In this case, a front portion of the contactless charger can be positioned between the left and right impact absorption members.

In this configuration, for example, because the contactless charger can be arranged by using a space between the impact absorption members which are compressed and deformed in a minor collision, it becomes possible to increase the size of the contactless charger, and a large-sized coil can easily be housed.

As described above, a cross member is provided which is suspended between a pair of left and right side frames positioned on vehicle-width-direction outer sides toward front, and a cross member arrangement portion in which the cross member is capable of being arranged is provided in a contactless charger which is arranged between the left and right side frames. Accordingly, layout characteristics of the contactless charger can be improved while impact absorbability in an offset collision is sufficiently secured.

An embodiment of the present invention will hereinafter be described in detail based on drawings. Note that the description of a preferable embodiment in the following is substantially only about examples and is not at all intended to restrict the present invention, applications thereof, or uses thereof.

<FIG> is a left side view of an electric vehicle (electric automobile) <NUM> including a vehicle-body front structure A according to the embodiment of the present invention. As illustrated in <FIG>, the electric vehicle <NUM> includes a lower structure <NUM> and an upper structure <NUM>. In <FIG>, a front bumper, a rear bumper, front and rear wheels, and so forth are omitted and are illustrated by imaginary lines, and each portion is schematically illustrated. In <FIG>, in addition to the components omitted in <FIG>, doors, a bonnet hood, a front fender, window glass, front and rear lighting devices, interior materials, and so forth are omitted, and each portion is schematically illustrated.

Note that in the description of the embodiment, a vehicle front side will simply be referred to as "front", a vehicle rear side will simply be referred to as "rear", a vehicle right side will simply be referred to as "right", and a vehicle left side will simply be referred to as "left". A right-left direction of the vehicle is a vehicle width direction.

As illustrated in <FIG>, the electric vehicle <NUM> is a passenger automobile. The electric vehicle <NUM> may be of any of a sedan type, a hatch-back type, a minivan type, and so forth, and its shape is not particularly limited. As illustrated in <FIG>, in the electric vehicle <NUM>, a vehicle cabin R1 is formed which serves as a staying space for an occupant. As illustrated in <FIG>, a front seat S1 is provided on a front side in the vehicle cabin R1, and a rear seat S2 is provided in rear of the front seat S1 in the vehicle cabin R1. In the rear of the rear seat S2, a trunk R2 is provided in accordance with necessity. The vehicle cabin R1 and the trunk R2 are provided to the upper structure <NUM>. Note that in the vehicle cabin R1, only the front seat S1 may be provided, or a third row seat (not illustrated) may be provided in the rear of the rear seat S2.

Meanwhile, a space in front of the vehicle cabin R1 as a front portion of the electric vehicle <NUM> can be set as a power chamber R3, for example. That is, the vehicle-body front structure A is provided to the electric vehicle <NUM> which includes a front-side traveling motor M1, a rear-side traveling motor M2, batteries B supplying electric power to the traveling motors M1 and M2, and a battery casing <NUM> housing the batteries B. The battery casing <NUM> is disposed below a floor panel <NUM> described later.

The front-side traveling motor M1 produces a driving force for driving left and right front wheels FT, and the front-side power train PT1 is configured with only the front-side traveling motor M1 or with the front-side traveling motor M1, a speed reducer, a transmission, and so forth. Further, the rear-side traveling motor M2 produces a driving force for driving left and right rear wheels RT, and a rear-side power train PT2 is configured with only the rear-side traveling motor M2 or with the rear-side traveling motor M2, a speed reducer, a transmission, and so forth.

In the present embodiment, the rear-side traveling motor M2 is configured to produce a highest output (maximum torque) which is high compared to the front-side traveling motor M1, and the rear-side traveling motor M2 has a larger size than the front-side traveling motor M1. Accompanying that, the rear-side power train PT2 becomes larger than the front-side power train PT1. Note that the rear-side traveling motor M2 may produce a highest output which is low compared to the front-side traveling motor M1, or the rear-side traveling motor M2 and the front-side traveling motor M1 may produce equivalent highest outputs. Further, only the front-side power train PT1 may be provided, or only the rear-side power train PT2 may be provided.

As illustrated in <FIG>, the lower structure <NUM> includes the battery casing <NUM>, a pair of left and right front side frames <NUM> and <NUM> which extend forward in front of the battery casing <NUM>, and a pair of left and right rear frame <NUM> and <NUM> which extend rearward in the rear of the battery casing <NUM>. A reference numeral <NUM> denotes the left front side frame, and a reference numeral <NUM> denotes the right front side frame. A reference numeral <NUM> denotes the left rear frame, and a reference numeral <NUM> denotes the right rear frame.

In a case of a common electric automobile, a battery casing is often formed as a separate body from a vehicle body and is often detachable from a portion below a floor; however, in the present embodiment, not only the battery casing <NUM> but also the left and right front side frames <NUM> and <NUM> and the left and right rear frames <NUM> and <NUM> are integrated with the battery casing <NUM>, and the front side frames <NUM> and <NUM> and the rear frames <NUM> and <NUM> together with the battery casing <NUM> are detachable from the upper structure <NUM>.

Specifically, the electric vehicle <NUM> of the present embodiment is configured to be capable of being divided, in an up-down direction, into the lower structure <NUM> having the battery casing <NUM> and the upper structure <NUM> forming the vehicle cabin R1 and the trunk R2. Being capable of being divided in the up-down direction means that without using welding, adhesion, or the like, the lower structure <NUM> is integrated with the upper structure <NUM> by using fastening members such as bolts, nuts, and screws. Accordingly, because the lower structure <NUM> can be separated from the upper structure <NUM> in accordance with necessity when maintenance or repairs are performed after the electric vehicle <NUM> is passed into the hands of a user, high maintainability is achieved. Note that fastening members used in the following description include bolts, nuts, screws, and so forth.

Here, as a vehicle-body structure of an automobile, a vehicle-body structure of a ladder frame type has been known. In a case of the vehicle-body structure of the ladder frame type, the vehicle-body structure is being capable of being divided, in the up-down direction, into a ladder frame and a cabin, but the ladder frame continuously extends in a front-rear direction and thus mainly receives a collision load in a front collision and a rear collision. In a side collision, the ladder frame only subsidiarily receives a collision load, and the collision load is mainly received by the cabin. As described above, in the vehicle-body structure of the ladder frame type, usually, different members receive collision loads between the front collision and rear collision and the side collision.

On the other hand, in a case of the electric vehicle <NUM> of the present embodiment, the lower structure <NUM> having the front side frames <NUM> and <NUM> and the rear frame <NUM> and <NUM> and the upper structure <NUM> are capable of being divided; however, a technical idea of the present embodiment is largely different from the vehicle-body structure of the ladder frame type in related art in the point that in both cases of the front collision and rear collision and the side collision, a collision load is received by the lower structure <NUM> and the upper structure <NUM>, and the collision load is capable of being dispersedly absorbed by both of the structures <NUM> and <NUM>. In the following, structures of the lower structure <NUM> and the upper structure <NUM> will be described in detail.

First, the upper structure <NUM> will be described. As illustrated in <FIG>, the upper structure <NUM> includes the floor panel <NUM>, a dash panel <NUM>, a pair of left and right front main frames <NUM> and <NUM>, and a pair of left and right side sills <NUM> and <NUM>. A reference numeral <NUM> denotes the left front main frame, and a reference numeral <NUM> denotes the right front main frame. A reference numeral <NUM> denotes the left side sill, and a reference numeral <NUM> denotes the right side sill.

The floor panel <NUM> configures a floor surface of the vehicle cabin R1 and is formed with a steel plate or the like which extends in the front-rear direction and extends also in the left-right direction. A space above the floor panel <NUM> serves as the vehicle cabin R1. A roof <NUM> is provided to an upper portion of the vehicle cabin R1. Further, in both of left and right side portions of the upper structure <NUM>, front openings 3a and rear openings 3b are formed. As illustrated in <FIG>, the front opening 3a and the rear opening 3b are capable of being opened and closed by a front door <NUM> and a rear door <NUM>, respectively. Note that although not illustrated, a front door and a rear door are disposed on a right side of the upper structure <NUM> to be capable of being opened and closed.

The dash panel <NUM> is a member for partitioning the vehicle cabin R1 from the power chamber R3 in the front-rear direction. The dash panel <NUM> is configured with a steel plate or the like, for example, extends in the left-right direction, and extends also in an up-down direction. On both of left and right sides of a front portion of the upper structure <NUM>, left and right front wheel well portions <NUM> and <NUM> for housing the left and right front wheels FT are respectively provided. A left end portion of the dash panel <NUM> is connected with the left front wheel well portion <NUM>, and a right end portion of the dash panel <NUM> is connected with the right front wheel well portion <NUM>.

The left and right front main frames <NUM> and <NUM> are disposed in a vehicle-body front portion and are highly strong members which extend in the front-rear direction. That is, the left and right front main frames <NUM> and <NUM> are positioned in front of the floor panel <NUM>, are positioned above the floor panel <NUM>, and are specifically disposed to extend forward from both of left and right sides in a lower portion of the dash panel <NUM>.

The left and right front main frames <NUM> and <NUM> form a left-right symmetrical structure and can be configured by joining plural press-formed materials or can be configured with the extruded material, for example. A cross section of each of the front main frames <NUM> and <NUM> in a direction orthogonal to the front-rear direction is set larger than a cross section of each of the front side frames <NUM> and <NUM> of the lower structure <NUM> in the same direction. Accordingly, the front main frames <NUM> and <NUM> become thick and highly strong members compared to the front side frames <NUM> and <NUM>.

Front end portions of the left and right front main frames <NUM> and <NUM> respectively have the crush cans 72a and 73a which perform compressive deformation in a front collision and absorb collision energy. The crush cans 72a and 73a are tubular members which extend in the front-rear direction. The crush cans 72a and 73a perform compressive deformation due to an impact load from the front in a phase previous to deformation of the front main frames <NUM> and <NUM> and thereby absorb the impact load. The front bumper reinforcement <NUM> extending in the left-right direction is fixed to front end portions of the left and right crush cans 72a and 73a.

The left and right side sills <NUM> and <NUM> are respectively disposed in both of left and right end portions of the floor panel <NUM> to extend in the front-rear direction. The left end portion of the floor panel <NUM> is connected with an intermediate portion of the left side sill <NUM> in the up-down direction, and the right end portion of the floor panel <NUM> is connected with an intermediate portion of the right side sill <NUM> in the up-down direction. Upper-side portions of the side sills <NUM> and <NUM> are protruded upward from connection portions with the floor panel <NUM>, and lower-side portions of the side sills <NUM> and <NUM> are protruded downward from the connection portions with the floor panel <NUM>. Because the battery casing <NUM> is arranged below the floor panel <NUM>, the battery casing <NUM> is arranged such that the lower-side portions of the side sills <NUM> and <NUM> overlap with the battery casing <NUM> in a vehicle side view. The battery casing <NUM> is fixed to the side sills <NUM> and <NUM>.

Next, the lower structure <NUM> will be described. The lower structure <NUM> includes the front and rear power trains PT1 and PT2, the front wheels FT, the rear wheels RT, front suspension apparatuses <NUM>, rear suspension apparatuses <NUM>, and so forth in addition to the battery casing <NUM>, the front side frames <NUM> and <NUM>, and the rear frames <NUM> and <NUM>. Forms of the front suspension apparatus <NUM> and the rear suspension apparatus <NUM> are not particularly specified.

The battery casing <NUM> is a large casing which is formed, below the floor panel <NUM> of the upper structure <NUM>, to be spanned from a left end portion vicinity to a right end portion vicinity of the floor panel <NUM> and to be spanned from a front end portion vicinity to a rear end portion vicinity of the floor panel <NUM>. As described above, the battery casing <NUM> is provided in a wide range of a lower region of the floor panel <NUM>, and it thereby becomes possible to install the battery B with a large capacity in the electric vehicle <NUM>. The battery B may be a lithium-ion battery, a solid-state battery, or the like or may be another secondary cell. Further, the battery B may be a so-called battery cell or may be a battery pack housing plural battery cells. In the present embodiment, the battery B is configured with a battery pack, and plural battery packs are installed in a state where those are aligned in the front-rear direction and the left-right direction.

The battery casing <NUM> includes a left-side battery frame <NUM>, a right-side battery frame <NUM>, a front-side battery frame <NUM>, a rear-side battery frame <NUM>, a bottom plate <NUM>, and the lid body <NUM> (illustrated in <FIG>). <FIG> illustrates a state where the lid body <NUM> is detached.

The left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, and the rear-side battery frame <NUM> are configured with an extruded material or the like of an aluminum alloy, for example, but may be configured with an aluminum alloy plate material or a press-formed material of a steel plate as well. The bottom plate <NUM> can be configured with an extruded material. In the following description, "extruded material" denotes an extruded material of an aluminum alloy, and "press-formed material" denotes an aluminum alloy plate material or a press-formed material of a steel plate. Further, each member may be configured with a casting, for example.

All of cross-sectional shapes of the left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, and the rear-side battery frame <NUM> in respective orthogonal directions to their longitudinal directions are rectangular shapes. Further, the left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, and the rear-side battery frame <NUM> are all arranged at the same height and extend in generally horizontal directions.

The left-side battery frame <NUM> is provided to a left-side portion of the battery casing <NUM> and extends in the front-rear direction. The right-side battery frame <NUM> is provided to a right-side portion of the battery casing <NUM> and extends in the front-rear direction. Further, the front-side battery frame <NUM> is provided to a front portion of the battery casing <NUM> and extends in the left-right direction. The rear-side battery frame <NUM> is provided to a rear portion of the battery casing <NUM> and extends in the left-right direction.

A left end portion of the front-side battery frame <NUM> is connected with a front end portion of the left-side battery frame <NUM>, and a right end portion of the front-side battery frame <NUM> is connected with a front end portion of the right-side battery frame <NUM>. A left end portion of the rear-side battery frame <NUM> is connected with a rear end portion of the left-side battery frame <NUM>, and a right end portion of the rear-side battery frame <NUM> is connected with a rear end portion of the right-side battery frame <NUM>. Consequently, the left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, and the rear-side battery frame <NUM> form a rack which surrounds all of the batteries B in a plan view.

The bottom plate <NUM> extends generally horizontally and is fixed to lower surfaces of the left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, and the rear-side battery frame <NUM>. Further, the lid body <NUM> is fixed to the lower surfaces of the left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, and the rear-side battery frame <NUM>. Consequently, a battery housing space S housing the batteries B (illustrated in <FIG>) is marked off and formed with the left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, the rear-side battery frame <NUM>, the bottom plate <NUM>, and the lid body <NUM>.

The size of the battery housing space S can be changed in accordance with the capacity of the installed batteries B. The size of the battery housing space S is capable of being easily changed by changing lengths of the left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, and the rear-side battery frame <NUM> and a shape of the bottom plate <NUM>. For example, in a case where the electric vehicle <NUM> is a small vehicle which has a short wheelbase and narrow treads, the left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, the rear-side battery frame <NUM> are made short, the shapes of the bottom plate <NUM> and the lid body <NUM> are made small in response to the shortening, and the battery housing space S thereby becomes small in accordance with the small vehicle. On the other hand, in a case of a large vehicle, the left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, and the rear-side battery frame <NUM> are made long, the shapes of the bottom plate <NUM> and the lid body <NUM> are made large in response to the elongation, and the battery housing space S thereby becomes large in accordance with the large vehicle. In a case where the left-side battery frame <NUM>, the right-side battery frame <NUM>, the front-side battery frame <NUM>, and the rear-side battery frame <NUM> are configured with the extruded material, the lengths can easily be changed. Further, the bottom plate <NUM> can be configured with the extruded material, and its shape can thereby easily be changed.

An upper portion of the battery housing space S may be closed by the above lid body <NUM> or may be closed by the floor panel <NUM> of the upper structure <NUM>. In the battery housing space S, other than the batteries B, a cooling device cooling the batteries B, a heating device heating the batteries B, and so forth (temperature adjustment devices) can also be provided. Further, electric power of the batteries B is supplied to the traveling motors M1 and M2 via a control device which is not illustrated. In the present embodiment, it is possible to charge the batteries B via a contactless charger <NUM> illustrated in <FIG>, and the batteries B are configured to be capable of being charged by a charging socket (not illustrated).

As illustrated in <FIG>, in the internal portion of the battery casing <NUM>, as strength members extending in the left-right direction, first to third inside-casing members 25A, 25B, and 25C are provided. All of heights of the first to third inside-casing members 25A, 25B, and 25C are the same and are generally the same as the heights of the left-side battery frame <NUM> and so forth. The inside-casing members 25A, 25B, and 25C may be configured with the extruded material or may be configured with the press-formed material. In the present embodiment, three inside-casing members 25A, 25B, and 25C are provided, but the number of inside-casing members 25A, 25B, and 25C may be increased or decreased in accordance with the dimension of the battery casing <NUM> in the front-rear direction.

The first to third inside-casing members 25A, 25B, and 25C are arranged at distances from each other in the front-rear direction, the first inside-casing member 25A is in a foremost position, and the third inside-casing member 25C is in a rearmost position. A lower portion of each of the inside-casing members 25A, 25B, and 25C is fixed to an upper surface of the bottom plate <NUM>. Further, a left end portion of each of the inside-casing members 25A, 25B, and 25C is fixed to an inner surface (right-side surface) of the left-side battery frame <NUM>, and a right end portion of each of the inside-casing members 25A, 25B, and 25C is fixed to an inner surface (left-side surface) of the right-side battery frame <NUM>. In other words, the inside-casing members 25A, 25B, and 25C are members which connect the left-side battery frame <NUM> and the right-side battery frame <NUM> together.

In the internal portion of the battery casing <NUM>, as strength members extending in the front-rear direction, a front central member <NUM> and first to third rear central members (rear reinforcement members) <NUM> to <NUM> are provided. The front central member <NUM> and the first to third rear central members <NUM> to <NUM> are arranged at generally the same heights and are provided at a center of the battery casing <NUM> in the left-right direction. Lower end portions of the front central member <NUM> and the first to third rear central members <NUM> to <NUM> are mounted on the upper surface of the bottom plate <NUM>.

The front central member <NUM> is arranged between the front-side battery frame <NUM> and the first inside-casing member 25A, a front end portion of the front central member <NUM> is fixed to a central portion of the front-side battery frame <NUM> in the left-right direction, and a rear end portion of the front central member <NUM> is fixed to a central portion of the first inside-casing member 25A in the left-right direction. Consequently, the front-side battery frame <NUM> is a member which extends so as to connect the front end portions of the left-side battery frame <NUM> and the right-side battery frame <NUM> with the front end portion of the front central member <NUM>.

The first rear central member <NUM> is arranged between the first inside-casing member 25A and the second inside-casing member 25B, a front end portion of the first rear central member <NUM> is fixed to the central portion of the first inside-casing member 25A in the left-right direction, and a rear end portion of the first rear central member <NUM> is fixed to a central portion of the second inside-casing member 25B in the left-right direction. Further, the second rear central member <NUM> is arranged between the second inside-casing member 25B and the third inside-casing member 25C, a front end portion of the second rear central member <NUM> is fixed to the central portion of the second inside-casing member 25B in the left-right direction, and a rear end portion of the second rear central member <NUM> is fixed to a central portion of the third inside-casing member 25C in the left-right direction. Further, the third rear central member <NUM> is arranged between the third inside-casing member 25C and the rear-side battery frame <NUM>, a front end portion of the third rear central member <NUM> is fixed to the central portion of the third inside-casing member 25C in the left-right direction, and a rear end portion of the third rear central member <NUM> is fixed to a central portion of the rear-side battery frame <NUM> in the left-right direction. Consequently, because the first to third inside-casing members 25A, 25B, and 25C and the front central member <NUM> and first to third rear central members <NUM> to <NUM> are disposed in a lattice manner in the internal portion of the battery casing <NUM> and are coupled with each other, a reinforcement effect for the battery casing <NUM> is further enhanced.

When an imaginary straight line extending in the front-rear direction is presumed in a plan view, the positions of the front central member <NUM> and the first to third rear central members <NUM> to <NUM> in the left-right direction are set such that the positions are arranged on the imaginary straight line. In other words, the first to third rear central members <NUM> to <NUM> are provided to be positioned on a rearward imaginary extension line of the front central member <NUM>. Note that the front central member <NUM> and the first to third rear central members <NUM> to <NUM> may be configured with one member which is continuous in the front-rear direction.

As illustrated in <FIG> and so forth, the vehicle-body front structure A includes the pair of left and right front side frames <NUM> and <NUM>, a frame bracket <NUM>, a first cross member <NUM>, a pair of left and right impact absorption members <NUM> and <NUM>, and a second cross member <NUM>. In the present embodiment, in addition to the above members, the vehicle-body front structure A includes a front member <NUM>, reinforcement members 19A and 19B, and so forth. Members configuring the vehicle-body front structure A are not limited to the above-described members and may include other members, apparatuses, devices, and so forth. Further, among the above-described members, members which do not serve as configuration elements required for the present invention may be omitted.

The front side frames <NUM> and <NUM> linearly and generally horizontally extend below left and right front main frames <NUM> and <NUM> provided to the upper structure <NUM>. The front side frames <NUM> and <NUM> can be configured with the extruded material, the press-formed material, or the like, for example. In the present embodiment, because the front side frames <NUM> and <NUM> are configured with the extruded material, their cross-sectional shapes in a direction orthogonal to the front-rear direction are generally equivalent from front end portions to rear end portions.

The left and right front side frames <NUM> and <NUM> are mounted on the front-side battery frame <NUM> configuring the front portion of the battery casing <NUM> via the frame bracket <NUM>. In other words, rear portions of the left and right front side frames <NUM> and <NUM> are coupled with the front-side battery frame <NUM> by the frame bracket <NUM>. The frame bracket <NUM> is an integrally formed component of metal and extends in the left-right direction along a front surface of the front-side battery frame <NUM>. The rear portions of the left and right front side frames <NUM> and <NUM> are fixed to the frame bracket <NUM>. Metal which configures the frame bracket <NUM> is not particularly limited. For example, aluminum and so forth can be raised, and in this case, the frame bracket <NUM> can be formed by aluminum die-casting.

The left and right front side frames <NUM> and <NUM> are mounted on the front-side battery frame <NUM> via the frame bracket <NUM>, but the rear portions of the front side frames <NUM> and <NUM> are caused to adjoin the front surface of the front-side battery frame <NUM>. Consequently, the front side frames <NUM> and <NUM> extend forward from the front-side battery frame <NUM>. Note that the rear portion of the front side frames <NUM> and <NUM> may slightly be spaced apart forward from the front surface of the front-side battery frame <NUM>. In this case also, viewing those as the whole, it can be considered that the front side frames <NUM> and <NUM> extend forward from the front-side battery frame <NUM>.

The rear portion of the left front side frame <NUM> is arranged to correspond to a section on a left side of a center of the front-side battery frame <NUM> in the left-right direction. Further, the rear portion of the right front side frame <NUM> is arranged to correspond to a section on a right side of the center of the front-side battery frame <NUM> in the left-right direction. Accordingly, a distance between the left and right front side frames <NUM> and <NUM> becomes a predetermined distance. A distance between the rear portions of the front side frames <NUM> and <NUM> is set narrower than a distance between the left-side battery frame <NUM> and the right-side battery frame <NUM> of the battery casing <NUM>.

Heights of the left and right front side frames <NUM> and <NUM> are generally the same. Further, the left and right front side frames <NUM> and <NUM>, the front central member <NUM> of the battery casing <NUM>, the left-side battery frame <NUM>, and the right-side battery frame <NUM> are disposed at generally the same heights.

The left and right front side frames <NUM> and <NUM> extend to be positioned on the vehicle-width-direction outer sides toward the front. That is, the left front side frame <NUM> is inclined with respect to the imaginary straight line extending in the front-rear direction of the vehicle in a plan view so as to be positioned on a left side toward the front. Further, the right front side frame <NUM> is inclined with respect to the imaginary straight line extending in the front-rear direction of the vehicle in a plan view so as to be positioned on a right side toward the front. Accordingly, the distance between the left and right front side frames <NUM> and <NUM> (a separation distance in the vehicle width direction) becomes wider toward the front, and in a portion between the left and right front side frames <NUM> and <NUM>, a space C is formed in which all or a part of various components, apparatuses, devices, and so forth are capable of being arranged. Then, the space C has a shape which is enlarged in the vehicle width direction toward the front.

In the present embodiment, the contactless charger <NUM> is arranged in the space C formed between the left and right front side frames <NUM> and <NUM>. The contactless charger <NUM> is configured to be capable of receiving a charging current for the batteries B from the outside. Specifically, the electric vehicle <NUM> conforms to a system which wirelessly transmits electric power by using electromagnetic induction (wireless power transmission system). Although not illustrated, the wireless power transmission system includes a power transmission coil placed directly below the electric vehicle <NUM> which stands still and the contactless charger <NUM> of a vehicle-mounted type. The power transmission coil is placed in a ground surface of a parking lot, a floor surface of a garage, or the like, for example.

The contactless charger <NUM> includes a power reception coil, a control device, and so forth (not illustrated) and a housing 4A which houses those. Electric power received by the power reception coil of the contactless charger <NUM> is supplied to the batteries B and is used as the charging current. The housing 4A is formed into a shape which is flat in the front-rear direction and the left-right direction, for example. Although not illustrated, an electric power cable or the like extends from the housing 4A. With the electric power cable, the batteries B are directly or indirectly connected.

An inclination angle of the left front side frame <NUM> with respect to the above imaginary straight line is equivalent to an inclination angle of a right front side frame <NUM> with respect to the above imaginary straight line. A front portion of the left front side frame <NUM> is arranged on a vehicle-width-direction inner side of the left-side battery frame <NUM> of the battery casing <NUM>. Further, a front portion of the right front side frame <NUM> is arranged on the vehicle-width-direction inner side of the right-side battery frame <NUM> of the battery casing <NUM>.

Further, as illustrated in <FIG>, positions, in the front-rear direction, of the front portions of the left and right front side frames <NUM> and <NUM> and of front portions of the left and right front main frames <NUM> and <NUM> of the upper structure <NUM> are set to generally the same positions.

As illustrated in <FIG>, the frame bracket <NUM> includes a vertical plate portion 40a which extends in the vehicle width direction and the up-down direction along the front surface of the front-side battery frame <NUM> and a lower plate portion 40b which extends rearward from a lower edge portion of the vertical plate portion 40a along the lower surface of the front-side battery frame <NUM> and which extends also in the vehicle width direction. The vertical plate portion 40a and the lower plate portion 40b are fixed to the front-side battery frame <NUM> by fastening members or the like. In such a manner, the vertical plate portion 40a and the lower plate portion 40b of the frame bracket <NUM> are respectively fixed to the front surface and the lower surface of the front-side battery frame <NUM>, and mounting rigidity of the frame bracket <NUM> on the front-side battery frame <NUM> can thereby be enhanced.

In the vertical plate portion 40a of the frame bracket <NUM>, a left-side insertion hole 40c into which the rear portion of the left front side frame <NUM> is inserted and a right-side insertion hole 40d into which the rear portion of the right front side frame <NUM> is inserted are formed at a distance in the vehicle width direction. The rear portion of the left front side frame <NUM> is fixed to the frame bracket <NUM> by an adhesive, a fastening member, or the like, for example, in a state where the rear portion is inserted into the left-side insertion hole 40c.

As illustrated in <FIG>, the frame bracket <NUM> includes a left-side upper plate portion 40e which extends in the front-rear direction so as to cover an upper surface of the left front side frame <NUM> and a right-side upper plate portion 40f which extends in the front-rear direction so as to cover an upper surface of the right front side frame <NUM>. The left-side upper plate portion 40e and the upper surface of the left front side frame <NUM> are caused to adhere to each other by an adhesive, for example, and the right-side upper plate portion 40f and the upper surface of the right front side frame <NUM> are similarly caused to adhere to each other. Accordingly, the left and right front side frames <NUM> and <NUM> can firmly be fixed to the frame bracket <NUM>.

The frame bracket <NUM> has a left-side support portion <NUM> and a right-side support portion <NUM>, and the left-side support portion <NUM> and the right-side support portion <NUM> are integrally shaped with the vertical plate portion 40a and the lower plate portion 40b. The left-side support portion <NUM> is a portion which is arranged on the vehicle-width-direction outer side (left side) of the left front side frame <NUM> and supports the above front side frame <NUM> from the vehicle-width-direction outer side. Specifically, the left-side support portion <NUM> is protruded forward from a left-side portion of the left-side insertion hole 40c in the vertical plate portion 40a and extends along a left side surface of the left front side frame <NUM>. A front portion of the left-side support portion <NUM> reaches the vicinity of a central portion of the left front side frame <NUM> in the front-rear direction, and it thus becomes possible to support a wide range of the left-side support portion <NUM> by the left-side support portion <NUM>. It is also possible to cause the left front side frame <NUM> to adhere to the left-side support portion <NUM>.

Further, the right-side support portion <NUM> is a portion which is arranged on the vehicle-width-direction outer side (right side) of the right front side frame <NUM> and supports the above front side frame <NUM> from the vehicle-width-direction outer side. Specifically, the right-side support portion <NUM> is protruded forward from a right-side portion of the right-side insertion hole 40d in the vertical plate portion 40a and extends along a right side surface of the right front side frame <NUM>. A front portion of the right-side support portion <NUM> reaches the vicinity of a central portion of the right front side frame <NUM> in the front-rear direction, and it thus becomes possible to support a wide range of the right-side support portion <NUM> by the right-side support portion <NUM>. It is also possible to cause the right front side frame <NUM> to adhere to the right-side support portion <NUM>.

On the vehicle-width-direction outer side of the frame bracket <NUM>, left and right suspension arms 20A configuring the front suspension apparatuses <NUM> are supported to be swingable in the up-down direction. That is, in a portion on a left side of the left-side support portion <NUM> in the frame bracket <NUM>, a left-side arm mounting portion <NUM> is provided to be protruded to a left side. On the left-side arm mounting portion <NUM>, a base end portion of the left suspension arm 20A is mounted to be rotatable around a shaft extending in the front-rear direction. Further, in a portion on a right side of the right-side support portion <NUM> in the frame bracket <NUM>, a right-side arm mounting portion <NUM> is provided to be protruded to a right side. On the right-side arm mounting portion <NUM>, a base end portion of the right suspension arm 20A is mounted to be rotatable around a shaft extending in the front-rear direction.

The first cross member <NUM> is a member, which is suspended between a portion of the left front side frame <NUM> which is spaced apart forward from the front-side battery frame <NUM> and a portion of the right front side frame <NUM> which is spaced apart forward from the front-side battery frame <NUM>, and linearly extends in the vehicle width direction. The first cross member <NUM> can also be configured with the extruded material, the press-formed member, or the like. In the present embodiment, a left-side portion of the first cross member <NUM> is fixed to the front portion of the left front side frame <NUM>, and a right-side portion of the first cross member <NUM> is fixed to the front portion of the right front side frame <NUM>. Consequently, the front portions of the left and right front side frames <NUM> and <NUM> are coupled with each other by the first cross member <NUM>.

Further, the first cross member <NUM> is generally parallel with the front-side battery frame <NUM>. Accordingly, in a plan view, a rectangular shape (a trapezoidal shape in the present example) is formed with the first cross member <NUM>, the left and right front side frames <NUM> and <NUM>, and the front-side battery frame <NUM>, and a closed cross-section is configured when a horizontal cross section is seen.

A left side of the first cross member <NUM> is protruded to the vehicle-width-direction outer side of the front portion of the left front side frame <NUM>. Further, a right side of the first cross member <NUM> is protruded to the vehicle-width-direction outer side of the front portion of the right front side frame <NUM>.

The first cross member <NUM> has an intermediate member portion 15A which is positioned in an intermediate portion in the vehicle width direction and left and right outside member portions 15B and 15C which extend from both end portions of the intermediate member portion 15A in the vehicle width direction toward vehicle-width-direction outer sides and are coupled with the left and right front side frames <NUM> and <NUM>. The intermediate member portion 15A is a portion which is arranged in the space C formed between the left and right front side frames <NUM> and <NUM>. The left outside member portion 15B is a portion which is fixed to the left front side frame <NUM>. The right outside member portion 15C is a portion which is fixed to the right front side frame <NUM>.

In the space C formed between the left and right front side frames <NUM> and <NUM>, the intermediate member portion 15A is arranged, and the above contactless charger <NUM> is also arranged. Because the contactless charger <NUM> includes a large-sized coil which is capable of receiving a large current, its dimension in the front-rear direction becomes long, and the contactless charger <NUM> is in a positional relationship in which a part of the contactless charger <NUM> overlaps with the intermediate member portion 15A in a plan view. As a measure against this, it is possible to arrange the contactless charger <NUM> above the intermediate member portion 15A, but in such a case, the contactless charger <NUM> is spaced apart from the power transmission coil, and charging efficiency is lowered. It is possible to arrange the contactless charger <NUM> below the intermediate member portion 15A instead, but in such a case, a minimum ground clearance becomes low. As another measure, it is also possible to dispose the contactless charger <NUM> below the floor panel <NUM>, but because the batteries B are installed below the floor panel <NUM>, how to secure the minimum ground clearance becomes a problem. As a still another measure, it is also possible to dispose the contactless charger <NUM> below a vehicle-body rear portion, but because the contactless charger <NUM> includes a large-sized coil as described above, each of a thickness dimension and the dimension in the front-rear direction is long, and as a result, how to secure a departure angle becomes a problem.

In the present embodiment, in order to establish layout even in the positional relationship in which a part of the contactless charger <NUM> overlaps with the intermediate member portion 15A of the first cross member <NUM> in a plan view, the contactless charger <NUM> has a cross member arrangement portion 4a in which the intermediate member portion 15A of the first cross member <NUM> is capable of being arranged.

More particularly, said cross member arrangement portion 4a may form an accommodation portion in which a part of the cross member <NUM> may be accommodated and/or through which the cross member <NUM> may extend. The contactless charger <NUM>, in particular the housing of the contactless charger <NUM>, may define a virtual enveloping contour through which the cross member <NUM> may extend due to the provision of the aforementioned cross member arrangement portion 4a. Said cross member <NUM> may be at least partly countersunk into said enveloping contour of the charger <NUM> and/or into the housing thereof, and/or may be flush countersunk into the enveloping contour or housing of the contactless charger <NUM>. For example, a lower side of the cross member <NUM> may be substantially flush with a lower side of the contactless charger <NUM>.

Specifically, as illustrated in <FIG> and so forth, the cross member arrangement portion 4a is configured with a recess portion or groove-like channel, which is capable of housing the intermediate member portion 15A, and has a shape which opens in a lower surface of the housing 4A of the contactless charger <NUM>. As illustrated in <FIG>, because the intermediate member portion 15A is continuous in the left-right direction, the cross member arrangement portion 4a is also continuous in the left-right direction from a left end portion to a right end portion of the housing 4A while corresponding to the shape of the intermediate member portion 15A. Consequently, it can be considered that the cross member arrangement portion 4a is configured with a groove portion which is capable of housing the intermediate member portion 15A. An inner surface of the cross member arrangement portion 4a may or may not contact with the intermediate member portion 15A.

Because the cross member arrangement portion 4a is open downward, the contactless charger <NUM> may be attached such that the first cross member <NUM> is housed in the cross member arrangement portion 4a of the contactless charger <NUM> when the vehicle is manufactured, for example, and attachment workability becomes high. The first cross member <NUM> is housed in the cross member arrangement portion 4a, it thereby becomes possible to lower the contactless charger <NUM> to the vicinity of a lower end of the vehicle body, and charging efficiency is improved.

Note that although not illustrated, in a case where the first cross member <NUM> is inclined with respect to a center line in a vehicle front-rear direction, the cross member arrangement portion 4a may be inclined so as to correspond to the first cross member <NUM>. Further, in a case where plural first cross members <NUM> are provided, plural cross member arrangement portions 4a can be formed.

Because the cross member arrangement portion 4a is provided to the flat housing 4A, a dimension of the cross member arrangement portion 4a in the up-down direction is set equivalent to or more than <NUM>/<NUM> of a dimension of the housing 4A in the up-down direction. Note that the dimension of the cross member arrangement portion 4a in the up-down direction is not particularly limited, and it is sufficient that the dimension is shorter than the dimension of the housing 4A in the up-down direction.

In an internal portion of the housing 4A, coils can respectively be housed in a portion on a front side of and a portion on a rear side of the cross member arrangement portion 4a, and in addition, it is possible to house the coil only in one of the portion on the front side of and the portion on the rear side of the cross member arrangement portion 4a and to house a control device or the like in the other. Further, in accordance with necessity, a control device or the like may be housed in a portion above the cross member arrangement portion 4a in the internal portion of the housing 4A.

The second cross member <NUM> is arranged in the rear of the contactless charger <NUM>. Specifically, the second cross member <NUM> is a member, which is arranged between the first cross member <NUM> and the front-side battery frame <NUM> and is suspended between the left front side frame <NUM> and the right front side frame <NUM>, and linearly extends in the vehicle width direction. The second cross member <NUM> can also be configured with the extruded material, the press-formed member, or the like. A dimension of the second cross member <NUM> in the vehicle width direction is shorter than a dimension of the first cross member <NUM> in the vehicle width direction.

As also illustrated in <FIG>, a left end portion of the second cross member <NUM> is fixed to a right side surface of the left front side frame <NUM> by adhesion, welding, a fastening member, or the like. A right end portion of the second cross member <NUM> is similarly fixed to a left side surface of the right front side frame <NUM>. Accordingly, intermediate portions of the left and right front side frames <NUM> and <NUM> in the front-rear direction are coupled with each other.

Further, the second cross member <NUM> is generally parallel with the front-side battery frame <NUM>. Accordingly, in a plan view, a rectangular shape (a trapezoidal shape in the present example) is formed with the second cross member <NUM>, the left and right front side frames <NUM> and <NUM>, and the front-side battery frame <NUM>, and a closed cross-section is configured when a horizontal cross section is seen. Further, in a plan view, a rectangular shape is also formed with the second cross member <NUM>, the left and right front side frames <NUM> and <NUM>, and the first cross member <NUM>.

As illustrated in <FIG>, the left reinforcement member 19A extends rearward from a portion on a left side of a central portion of the second cross member <NUM> in the vehicle width direction to the front-side battery frame <NUM>. A rear portion of the left reinforcement member 19A is fixed to the right side surface of the left front side frame <NUM>. Further, the right reinforcement member 19B extends rearward from a portion on a right side of the central portion of the second cross member <NUM> in the vehicle width direction to the front-side battery frame <NUM>. A rear portion of the right reinforcement member 19B is fixed to the left side surface of the right front side frame <NUM>.

The left impact absorption member <NUM> is provided in front of the left front side frame <NUM> and is configured with a tubular member which extends forward. Further, the right impact absorption member <NUM> is provided in front of the right front side frame <NUM> and is configured with a tubular member which extends forward. Similarly to crush cans 72a and 73a of the upper structure <NUM>, the impact absorption members <NUM> and <NUM> perform compressive deformation due to an impact load from the front in a phase previous to deformation of the front side frames <NUM> and <NUM> and thereby absorb the impact load. As illustrated in <FIG>, positions, in the front-rear direction, of rear portions of the left and right impact absorption members <NUM> and <NUM> and of rear portions of the crush cans 72a and 73a of the upper structure <NUM> are set to generally the same positions.

The rear portion of the left impact absorption member <NUM> is fixed to the front portion of the left front side frame <NUM>. A direction in which the left impact absorption member <NUM> extends is along the longitudinal direction of the left front side frame <NUM>, and an axis line of the impact absorption member <NUM> is positioned on a forward extension line of the front side frame <NUM>. Further, the rear portion of the right impact absorption member <NUM> is fixed to the front portion of the right front side frame <NUM>. A direction in which the right impact absorption member <NUM> extends is along the longitudinal direction of the right front side frame <NUM>, and an axis line of the impact absorption member <NUM> is positioned on a forward extension line of the front side frame <NUM>. A front portion of the contactless charger <NUM> is positioned between the left and right impact absorption members <NUM> and <NUM>. Accordingly, because the contactless charger <NUM> can be arranged by using a space between the impact absorption members <NUM> and <NUM> which are compressed and deformed in a minor collision, it becomes possible to increase the size of contactless charger <NUM>, and a large-sized coil can easily be housed.

As illustrated in <FIG>, <FIG> and so forth, the front member <NUM> is a member which is suspended between the left and right impact absorption members <NUM> and <NUM>. A portion on a left side of a central portion of the front member <NUM> in the vehicle width direction is fixed to a front portion of the left impact absorption member <NUM>, and a portion on a right side of the central portion of the front member <NUM> in the vehicle width direction is fixed to a front portion of the right impact absorption member <NUM>. Accordingly, the left and right impact absorption members <NUM> and <NUM> are coupled together by the front member <NUM>. The front portion of the contactless charger <NUM> is positioned in the rear of the front member <NUM>.

As illustrated in <FIG>, positions, in the front-rear direction, of the front member <NUM> and of a front bumper reinforcement <NUM> of the upper structure <NUM> are set to generally the same positions, and the front member <NUM> is positioned directly below the front bumper reinforcement <NUM>.

As described above, the contactless charger <NUM> is arranged in the space C formed between the left and right front side frames <NUM> and <NUM>, that is, on a lower side of the vehicle-body front portion. Accordingly, how to secure the minimum ground clearance does not become a problem, and how to secure the departure angle does not become a problem either. The intermediate member portion 15A of the first cross member <NUM> is also arranged in the space C, but because the intermediate member portion 15A is arranged in the cross member arrangement portion 4a of the contactless charger <NUM>, layout characteristics of the contactless charger <NUM> are improved.

Further, because a structure is made in which the cross member arrangement portion 4a is open downward and the intermediate member portion 15A is capable of being inserted from a portion below the cross member arrangement portion 4a, the contactless charger <NUM> is not protruded downward in the vehicle-body front portion, and how to secure an approach angle does not become a problem.

Next, a description will be made about a collision of the electric vehicle <NUM> which is configured as described above. For example, in a case where a left side offset collision is presumed in which an impact load is input from obliquely left front, because the left front side frame <NUM> extends so as to correspond to an input direction of the impact load, the impact load from the obliquely left front is input generally along an axis direction of the left front side frame <NUM>, and the impact load is absorbed by the left front side frame <NUM>. In addition, the impact load input to the left front side frame <NUM> is transmitted to the front-side battery frame <NUM> and is thus also absorbed by the front-side battery frame <NUM>. In this case, because the left and right front side frames <NUM> and <NUM> are in a state where those are coupled together by the first cross member <NUM>, the front side frames <NUM> are less likely to collapse but are more likely to be axially compressed. The same applies to a right side offset collision.

Further, in a case where an impact load is input from front, because the second cross member <NUM> is positioned in the rear of the contactless charger <NUM>, the contactless charger <NUM> can be deformed or destroyed in front of the second cross member <NUM>. Accordingly, it becomes possible to absorb an impact by using the contactless charger <NUM>.

The above-described embodiment is merely an example in all respects and is not to be construed in a limited manner. Furthermore, all modifications and changes belonging to the equivalent scope of the claims are included in the scope of the present invention.
