Therefore, the heat generated by the plurality of battery cells of the battery is likely to accumulate, resulting in increasing the temperature of the battery cells. In the case that an operating temperature of the battery cells is generally in the range of <NUM>-<NUM> degrees, a charge-and-discharge performance of the battery cells is the best, and the operating life of the battery cells is the longest. How to control the operating temperature of the battery cells in the battery within an appropriate range is a technical problem that needs to be solved urgently in a technology filed of the battery.

<CIT> discloses a battery pack, a power utilization device and a manufacturing method of the battery pack. The battery pack includes a battery cell and a support. The battery cell includes two or more secondary batteries. The battery cell has a middle portion and two end portions. In the arrangement direction of the secondary batteries, the two end portions are located on the two sides of the middle portion respectively. The support is used for supporting the battery unit. The support comprises a body and a heat resisting part arranged on the body, and the heat resisting part is arranged corresponding to at least one end portion, so that the heat exchange amount of the end portion passing through the support is smaller than that of the middle part passing through the support.

The present application provides a battery, an electricity-consuming apparatus, a method for manufacturing the battery and a system of manufacturing the battery, which can improve the heat exchange efficiency and make the battery cells of the battery work at a suitable temperature.

In a first aspect, a battery provided by the present application includes.

In the above embodiments, the first plate body can exchange heat with the battery cells, so that the battery cell can work at a suitable temperature and improve the operation performance of the battery cells. The two second plate bodies can fix the battery cells from two sides to improve the structural strength and stability of the battery. The support portion can be directly mounted on the electricity-consuming apparatus, so that a traditional housing can be omitted, the space utilization rate can be improved, and the used members can be reduced. The heat-insulating structure can reduce the heat transfer between the heat-exchanging component and the support component, ensure the heat exchange rate between the battery cells and the heat-exchanging component, adjust the battery cells to an appropriate operating temperature in time, and prolong the operation life of the battery. Furthermore, by providing a second flow passage communicating with the first flow passage, the second flow passage being formed at an inside of the second plate bodies, the first plate body can exchange heat with the battery cells from below, and the second plate bodies can exchange heat with the battery cells from the sides, so that it can increase the heat exchange area of the battery cells, improve the heat exchange efficiency, reduce the temperature difference of the battery cells in a thickness direction of the first plate body, improve the consistency of the temperature of the battery cells, and improve the working performance of the battery cells. In the embodiments of the present application, by communicating the first flow passage with the second flow passage, there is no need to separately connect the first flow passage and the second flow passage to the external liquid supply pipeline, thereby simplifying the connecting structure between the heat-exchanging component and the external liquid supply pipeline.

In some embodiments, the heat-insulating structure includes a gap, and the gap is formed in at least a partial region between the support portion and the first plate body.

In the above embodiments, at least part of the first plate body is separated from the support portion by the gap, so as to reduce a contact area between the first plate body and the support portion, and reduce the heat transfer rate between the first plate body and the support portion.

In some embodiments, the heat-insulating structure further includes a heat-insulating layer, and the heat-insulating layer is arranged in the gap.

In the above embodiments, the heat-insulating layer can hinder the heat transfer between the first plate body and the support portion, and reduce the influence of the support portion on the temperature of the first plate body.

In some embodiments, the first plate body includes a first main body, a first convex portion and a second convex portion, and the first convex portion and the second convex portion protrude from a surface of the first main body away from the accommodating space. In a thickness direction of the first main body, a size of the first convex portion protruding from the first main body is smaller than a size of the second convex portion protruding from the first main body, the second convex portion is configured to support the first main body on a surface of the support portion, and at least part of the gap is formed between the support portion and the first convex portion. The first flow passage is formed at an inside of the first convex portion.

In the above embodiments, by providing the first convex portion, a partial thickness of the first plate body can increase, more space can be provided for the first flow passage, a flow area of the first flow passage can increase, and the heat exchange efficiency can be improved. The first convex portion protrudes toward a side away from the accommodating space, so that the flow area of the first flow passage can increase while avoiding the first flow passage from occupying the accommodating space. The support portion is arranged to be spaced apart from the first convex portion. Therefore, the gravitational loads of the battery cells and other components is transmitted to the support portion through the second convex portion instead of being transmitted to the support portion through the first convex portion, so that it can reduce the force of the first convex portion and reduce the risk of deformation and blockage of the first flow passage. The support portion is arranged to be space apart from the first convex portion, so that it can enlarge a heat transfer path between the support portion and the heat-exchanging medium in the first flow passage, reduce the heat transfer rate between the heat-exchanging medium and the support portion, reduce the influence of the temperature of the support portion on the heat-exchanging medium, and ensure the heat exchange efficiency between the heat-exchanging component and the battery cells.

In some embodiments, the battery further includes two end plates. The two end plates are respectively located at two ends of the battery unit in the second direction, and clamp and hold the battery unit; two ends of each of the end plates in the first direction are respectively connected to the two second plate bodies. Two ends of the support portion in the second direction include mounting regions, the mounting regions extend to outsides of the end plates and are configured to be fixed to an external frame.

In the above embodiments, the heat-exchanging component is connected to the end plates through the second plate bodies, so that it can improve the stability of the first plate body and reduce the risk of separation between the first plate body and the battery cells when the battery is shaken. The mounting regions of the support portion extend to the outsides of the end plates, so that the support portion can be directly fixed to the external frame, avoiding the end plates from interfering with the connection between the support portion and the external frame, and simplifying the structure of the battery.

In some embodiments, the battery further includes a joint. At least part of the first plate body protrudes to the outsides of the end plates and is configured to mount the joint, and the joint communicates with the first flow passage.

In the above embodiments, the joint is mounted at the outsides of the end plates, so an external liquid supply pipeline does not need to pass through the end plates, so that it can simplify the structure of the battery and make the arrangement of the external liquid supply pipeline more flexible.

In some embodiments, each of the mounting regions includes a mounting hole passed through, and the mounting hole is configured to be passed through by an external connector to be fixed to the external frame by the external connector; in the thickness direction of the support portion, the mounting hole is not covered by the heat-exchanging component.

In the above embodiments, the mounting hole is not covered by the heat-exchanging component, so that the heat-exchanging component can be prevented from interfering with mounting the external connector, and a mounting process between the battery and the external frame can be simplified.

In some embodiments, in a direction away from the support portion, each of the end plates and each of the second plate bodies extend beyond the battery cells, and an opening is formed at an end of the two end plates and the two second plate bodies away from the support portion. The battery further includes a cover plate located at a side of the battery unit away from the support portion and connected to the end plates and the second plate bodies to close the opening.

In the above embodiments, the cover plate, the end plates and the heat-exchanging component enclose a liquid enclosed space for accommodating the battery cells to prevent liquid or other foreign objects from affecting the charging or discharging of the battery cells. The battery cells do not need to be protected by the housing, and the battery of the embodiments can be directly mounted to the electricity-consuming apparatus, so that the space utilization rate can be saved and improved, and the used members can be reduced.

In some embodiments, the support component further includes two position-limiting portions, the two position-limiting portions are located at a side of the support portion facing to the heat-exchanging component and connected to the support portion, and in the first direction, the two second plate bodies are located between the two position-limiting portions.

In the above embodiments, the position-limiting portions can restrict the heat-exchanging component and the battery unit from two sides in the first direction. When the battery is shaken, the position-limiting portions can reduce the shaking amplitude of the heat-exchanging component and the battery unit, and improve the stability of the overall battery.

In some embodiments, each of the second plate bodies includes a second main body, a third convex portion and a fourth convex portion, and the third convex portion and the fourth convex portion protrude from a surface of the second main body away from the accommodating space. In a thickness direction of the second main body, a size of the third convex portion protruding from the second main body is smaller than a size of the fourth convex portion protruding from the second main body, so that the fourth convex portion is pressed against the position-limiting portions. The second flow passage communicating with the first flow passage is formed at an inside of the third convex portion.

In the above embodiments, by providing the third convex portion, a partial thickness of each of the second plate bodies can increase, more space can be provided for the second flow passage, the flow area of the second flow passage can increase, and the heat exchange efficiency can be improved. The third convex portion protrudes toward the side away from the accommodating space, so that the flow area of the second flow passage can increase while avoiding the second flow passage from occupying the accommodating space. Since a size of the third convex portion protruding from the second main body is smaller than a size of the fourth convex portion protruding from the second main body, when the battery is shaken, the fourth convex portion can serve as a stopper, reduce the possibility of components at the outsides of the second plate bodies pressing the third convex portion and reduce the risk of deformation and blockage of the second flow passage. The two position-limiting portions clamp and hold the heat-exchanging component from two sides through the fourth convex portion, so as to increase the connecting strength between the heat-exchanging component and the support component and improve the stability. In the embodiments, by providing the fourth convex portion, the third convex portion and the second main body can be separated from the position-limiting portions, and a contact area between the position-limiting portions and the second plate bodies can be reduced, so as to hinder the heat transfer between the second plate bodies and the position-limiting portions and reduce the influence of the position-limiting portions on the temperature of the second plate bodies.

In some embodiments, the first flow passage and the second flow passage communicate with each other at a junction between the first plate body and each of the second plate bodies; or the heat-exchanging component further includes a connecting pipeline, communicating the first flow passage with the second flow passage.

There are generally three types of the battery cell in terms of packaging manners: cylindrical battery cell, square battery cell, and soft-packed battery cell, which are not limited in the embodiments of the present application.

A battery mentioned in the embodiments of the present application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. The battery generally includes a housing for packaging one or more battery cells. The housing can prevent liquid or other foreign objects from affecting the charging or discharging of the battery cells.

The battery cell may generate heat during a process of charging and discharging. When a plurality of battery cells are used in sets, the heat may gather together. If the heat is not removed effectively, it will cause a temperature of the battery cells to rise and the aging of the battery cells to be accelerated. In addition, the too high temperature may easily cause the runaway heat, and cause the safety risk. When the battery cells are in a low temperature environment, the operation life will be shortened and the discharge capacity will be weakened.

The inventors tried to arrange a heat-exchanging component in the battery to control an operating temperature of the battery cells within an appropriate range. Specifically, a flow passage is usually formed at an inside of the heat-exchanging component. When an external heat exchange media flows through the flow passage of the heat-exchanging component, a heat-exchanging medium exchanges heat with the battery cells through the heat-exchanging component to adjust the temperature of the battery cells. The heat-exchanging component usually needs to be arranged on a load-bearing structure, and the load-bearing structure is configured to support the heat-exchanging component and the battery cells. However, the inventor found that the heat-exchanging component is easily affected by a temperature of the load-bearing structure. The heat-exchanging component exchanges heat with the battery cells and the load-bearing structure at the same time, resulting in that the heat exchange rate between the battery cells and the heat-exchanging component may decrease, and the operating temperature of the battery cells cannot be adjusted in time.

In view of these, the battery provided by the present application includes the heat-exchanging component, including a first plate body and two second plate bodies, in which the two second plate bodies are respectively connected to two ends of the first plate body in a first direction, a predetermined angle is formed between each of the second plate bodies and the first plate body, an accommodating space is enclosed by the first plate body and the two second plate bodies, the first plate body is provided with a first flow passage for the heat-exchanging medium to flow therein, and a second flow passage is formed at an inside of the second plate bodies and communicates with the first flow passage; a battery unit, in which the battery unit is at least partially accommodated in the accommodating space of the heat-exchanging component, the battery unit includes the plurality of battery cells sequentially arranged in a second direction, the heat-exchanging component is configured to adjust the temperature of the battery cells, and the second direction intersects with the first direction; and a support component, including a support portion located at a side of the first plate body away from the accommodating space, in which the support portion is connected to the first plate body and is configured to support the heat-exchanging component, and a heat-insulating structure is arranged between the support portion and the first plate body. In the embodiments of the present application, the heat-insulating structure is arranged between the heat-exchanging component and the support component, so as to reduce the heat exchange between the heat-exchanging component and the support component, ensure the heat exchange rate between the battery cells and the heat-exchanging component, and adjust the battery cells to the appropriate operating temperature in time.

The heat-insulating structure <NUM> can reduce the heat transfer between the heat-exchanging component <NUM> and the support component <NUM>, ensure the heat exchange rate between the battery cells <NUM> and the heat-exchanging component <NUM>, adjust the battery cells <NUM> to the appropriate operating temperature in time, and prolong the operation life of the battery <NUM>.

In some embodiments, the heat-insulating structure <NUM> includes a gap <NUM>, and the gap <NUM> is formed in at least a partial region between the support portion <NUM> and the first plate body <NUM>.

The gap <NUM> may or may not be filled with a heat-insulating material.

The gap <NUM> separates at least part of the first plate body <NUM> from the support portion <NUM> to reduce a contact area between the first plate body <NUM> and the support portion <NUM>, and reduce the heat transfer rate between the first plate body <NUM> and the support portion <NUM>.

In some embodiments, the heat-insulating structure <NUM> further includes a heat-insulating layer <NUM>, and the heat-insulating layer <NUM> is arranged in the gap <NUM>.

The heat-insulating layer <NUM> may fill the gap <NUM> between the first plate body <NUM> and the support portion <NUM>, or may fill only part of the gap <NUM>.

The heat-insulating layer <NUM> may be a whole piece or a plurality of pieces which are separated.

The heat conductivity of the heat-insulating layer <NUM> is smaller than the heat conductivity of the support portion <NUM> and the heat conductivity of the first plate body <NUM>.

The heat-insulating layer <NUM> can hinder the heat transfer between the first plate body <NUM> and the support portion <NUM> and reduce the influence of the support portion <NUM> on the temperature of the first plate body <NUM>. It should be noted that the heat-insulating layer <NUM> does not require the complete heat insulation, as long as the heat-conducting efficiency can be reduced, and a non-metallic material is preferable. For example, the heat-insulating layer <NUM> can be made of glass fiber, asbestos, rock wool, silicate, aerogel felt or the like.

Optionally, the heat-insulating layer <NUM> also has a connection function, which can reliably fix the first plate body <NUM> on the support portion <NUM> and improve the structural strength of the entire battery <NUM>. For example, the heat-insulating layer <NUM> is formed by curing an adhesive.

Optionally, the heat-insulating layer <NUM> also has a buffer function. The heat-insulating layer <NUM> has a good elasticity. When the battery <NUM> is shaken, the heat-insulating layer <NUM> can have a buffering effect to reduce an impact force received by the first plate body <NUM> and reduce the risk of deformation and blockage of the first flow passage <NUM>.

In some embodiments, the first plate body <NUM> includes a first main body <NUM>, a first convex portion <NUM> and a second convex portion <NUM>, and the first convex portion <NUM> and the second convex portion <NUM> protrude from a surface of the first main body <NUM> away from the accommodating space <NUM>. In a thickness direction of the first main body <NUM>, a size of the first convex portion <NUM> protruding from the first main body <NUM> is smaller than a size of the second convex portion <NUM> protruding from the first main body <NUM>, the second convex portion <NUM> is configured to support the first main body <NUM> on a surface of the support portion <NUM>, and at least part of the gap <NUM> is formed between the support portion <NUM> and the first convex portion <NUM>. The first flow passage <NUM> is formed at an inside of the first convex portion <NUM>.

The first main body <NUM> is a flat plate structure substantially, and surfaces of the first main body <NUM> oppositely arranged in a thickness direction of the first main body <NUM> are flat surfaces.

There may be one or more first convex portion <NUM>. When there are a plurality of first convex portions <NUM>, each of first convex portions <NUM> is provided with the first flow passage <NUM>; the first flow passages <NUM> of the plurality of first convex portions <NUM> may be connected directly, or may be connected through other communication structures, such as a connecting pipeline or the like.

There may be one or more second convex portion <NUM>. The second convex portion <NUM> may be circular, rectangular, racetrack-shaped, elliptical or the like. The second convex portion <NUM> may be connected to the support portion <NUM> by means of riveting, bolting, welding, bonding or the like. Optionally, the second convex portion <NUM> is arranged at a lower side of each of the battery cells <NUM>, so that the heat-exchanging component <NUM> can transmit the gravitational load to the support portion <NUM> more evenly, so as to reduce the stress concentration.

An extent to which the second convex portion <NUM> protrudes from the first main body <NUM> is greater than an extent to which the first convex portion <NUM> protrudes from the first main body <NUM>. Therefore, the second convex portion <NUM> can press against the support portion <NUM> to support and hold the first main body <NUM> and the first convex portion <NUM>, and to space the first convex portion <NUM> apart from the support portion <NUM>.

In the embodiments of the present application, by arranging the first convex portion <NUM>, a partial thickness of the first plate body <NUM> can increase to provide more space for the first flow passage <NUM>, increase a flow area of the first flow passage <NUM>, and improve the heat exchange efficiency. The first convex portion <NUM> protrudes toward a side away from the accommodating space <NUM>, so that the flow area of the first flow passage <NUM> can increase while preventing the first flow passage <NUM> from occupying the accommodating space <NUM>. The support portion <NUM> is spaced apart from the first convex portion <NUM>. Therefore, the gravitational loads of the battery cells <NUM> and other components is transmitted to the support portion through the second convex portion <NUM> instead of being transmitted to the support portion <NUM> through the first convex portion <NUM>, so that it can reduce the force of the first convex portion <NUM> and reduce the risk of deformation and blockage of the first flow passage. The support portion <NUM> is arranged to be space apart from the first convex portion <NUM>, so that it can enlarge a heat transfer path between the support portion <NUM> and the heat-exchanging medium in the first flow passage <NUM>, reduce the heat transfer rate between the heat-exchanging medium and the support portion <NUM>, reduce the influence of the temperature of the support portion <NUM> on the heat-exchanging medium, and ensure the heat exchange efficiency between the heat-exchanging component <NUM> and the battery cells <NUM>.

In some embodiments, the first plate body <NUM> is provided with a first concave portion <NUM> at a position corresponding to the second convex portion <NUM>, and the first concave portion <NUM> is recessed relative to the surface of the first main body <NUM> facing the accommodation space <NUM>. The first concave portion <NUM> can reduce the weight of the first plate body <NUM> and increase the elasticity of the second convex portion <NUM>, so that the second convex portion <NUM> has the certain buffering effect.

The second flow passage <NUM> is configured to communicate with the external liquid supply pipeline, and the heat-exchanging medium can circulate and flow between the second flow passage <NUM> and the external liquid supply pipeline to exchange heat with the battery cells <NUM> through the second plate bodies <NUM>, so that the battery cells <NUM> can work at the appropriate temperature.

In the embodiments, the first plate <NUM> can exchange heat with the battery cells <NUM> from below, and the second plate bodies <NUM> can exchange heat with the battery cells <NUM> from the sides, so that it can increase the heat exchange area of the battery cells <NUM>, improve the heat exchange efficiency, reduce the temperature difference of the battery cells <NUM> in a thickness direction of the first plate body <NUM>, improve the consistency of the temperature of the battery cells <NUM>, and improve the working performance of the battery cells <NUM>.

In some embodiments, the second flow passage <NUM> communicating with the first flow passage <NUM> is formed at an inside of the second plate bodies <NUM>.

The second flow passage <NUM> may directly communicate with the first flow passage <NUM>, or may indirectly communicate with the first flow passage <NUM> through other components, which is not limited in the embodiments.

In the embodiments of the present application, the first flow passage <NUM> communicates with the second flow passage <NUM>, thus, there is no need to separately connect the first flow passage <NUM> and the second flow passage <NUM> to the external liquid supply pipeline, thereby simplifying the connecting structure between the heat-exchanging component <NUM> and the external liquid supply pipeline.

In some embodiments, the support component <NUM> further includes two position-limiting portions <NUM>, the two position-limiting portions <NUM> are located at a side of the support portion <NUM> facing to the heat-exchanging component <NUM> and connected to the support portion <NUM>, and in the first direction Y, the two second plate bodies <NUM> are located between the two position-limiting portions <NUM>.

The position-limiting portion <NUM> may be integrally formed with the support portion <NUM>, or may be connected to the support portion <NUM> by means of welding, riveting, bonding or the like.

A certain angle is formed between the position-limiting portion <NUM> and the support portion <NUM>. Optionally, the angle between the position-limiting portion <NUM> and the support portion <NUM> may be <NUM>°-<NUM>°.

The position-limiting portions <NUM> can restrict the heat-exchanging component <NUM> and the battery unit <NUM> from two sides in the first direction Y. When the battery <NUM> is shaken, the position-limiting portions <NUM> can reduce the shaking amplitude of the heat-exchanging component <NUM> and the battery unit <NUM>, and improve the stability of the overall battery <NUM>.

The position-limiting portion <NUM> may be connected to the second plate bodies <NUM> by means of riveting, bolting, welding, bonding or the like, so as to improve the overall structural strength of the battery <NUM> and improve stability of the overall battery <NUM>.

In some embodiments, a heat-insulating structure may also be arranged between the position-limiting portion <NUM> and the second plate bodies <NUM> to hinder the heat transfer between the second plate bodies <NUM> and the position-limiting portion <NUM> and reduce the influence of the position-limiting portion <NUM> on the temperature of the second plate bodies <NUM>. The heat-insulating structure between the position-limiting portion <NUM> and the second plate bodies <NUM> includes, but is not limited to, structures such as the gap, the heat-insulating layer (not shown) and the like.

In some embodiments, each of the second plate bodies <NUM> includes a second main body <NUM>, a third convex portion <NUM> and a fourth convex portion <NUM>, and the third convex portion <NUM> and the fourth convex portion <NUM> protrude from a surface of the second main body <NUM> away from the accommodating space <NUM>. In a thickness direction of the second main body <NUM>, a size of the third convex portion <NUM> protruding from the second main body <NUM> is smaller than a size of the fourth convex portion <NUM> protruding from the second main body <NUM>, so that the fourth convex portion <NUM> is pressed against the position-limiting portion <NUM> The second flow passage <NUM> communicating with the first flow passage <NUM> is formed at an inside of the third convex portion <NUM>.

The second main body <NUM> is a flat plate structure substantially, and the surfaces of the second main body <NUM> oppositely arranged in the thickness direction of its own can be flat surfaces.

There may be one or more third convex portions <NUM>. When there is a plurality of third convex portions <NUM>, the second flow passage <NUM> is formed in each of the third convex portions <NUM>; the second flow passages <NUM> of the plurality of third convex portions <NUM> may directly communicate with one another, or may communicate with one another through other communication structures, such as the connecting pipeline or the like.

There may be one or more fourth convex portions <NUM>. The fourth convex portion <NUM> may be circular, rectangular, racetrack-shaped, elliptical or the like.

An extent to which the fourth convex portion <NUM> protruding from the second main body <NUM> is greater than an extent to which the third convex portion <NUM> protruding from the second main body <NUM>.

In the embodiments of the present application, by arranging the third convex portion <NUM>, a partial thickness of each of the second plate bodies <NUM> can increase, so as to provide more space for the second flow passage <NUM>, increase the flow area of the second flow passage <NUM>, and improve the heat exchange efficiency. The third convex portion <NUM> protrudes toward the side away from the accommodating space <NUM>, so that the flow area of the second flow passage <NUM> can increase while preventing the second flow passage <NUM> from occupying the accommodating space <NUM>. Since the size of the third convex portion <NUM> protruding from the second main body <NUM> is smaller than the size of the fourth convex portion <NUM> protruding from the second main body <NUM>, when the battery <NUM> is shaken, the fourth convex portion <NUM> can serve as a stopper; so as to reduce the possibility of a component at the outsides of the second plate bodies <NUM> pressing the third convex portion <NUM>, and reduce the risk of deformation and blockage of the second flow passage <NUM>.

The two position-limiting portions <NUM> clamp and hold the heat-exchanging component <NUM> from two sides through the fourth convex portion <NUM>, so as to increase the connection strength between the heat-exchanging component <NUM> and the support component <NUM> and improve the stability. In the embodiments, by providing the fourth convex portion <NUM>, the third convex portion <NUM> and the second main bodies <NUM> can be separated from the position-limiting portion <NUM>, so that the contact area between the position-limiting portion <NUM> and the second plate bodies <NUM> can be reduced to hinder the heat transfer between the second plate bodies <NUM> and the position-limiting portion <NUM>, and reduce the influence of the position-limiting portion <NUM> on the temperature of the second plate bodies <NUM>.

In the first direction Y, the position-limiting portion <NUM> may overlap with the third convex portion <NUM>, or may not overlap with the third convex portion <NUM>. Even if the position-limiting portion <NUM> overlaps with the third convex portion <NUM> in the first direction Y, the fourth convex portion <NUM> can support and hold the position-limiting portion <NUM>, so that the position-limiting portion <NUM> can be spaced apart from the third convex portion <NUM>, thereby preventing the third convex portion <NUM> from being pressed by the position-limiting portion <NUM>, and reducing the heat transfer between the third convex portion <NUM> and the position-limiting portion <NUM>.

In some embodiments, the second concave portion <NUM> is provided with the second plate bodies <NUM> arranged at a position corresponding to the fourth convex portion <NUM>, and the second concave portion <NUM> is recessed relative to the surface of the second main body <NUM> facing to the accommodating space <NUM>. The second concave portion <NUM> can reduce the weight of the second plate bodies <NUM> and increase the elasticity of the fourth convex portion <NUM>, so that the fourth convex portion <NUM> has the certain buffering effect.
