Patent Description:
In general, an electric vehicle refers to a vehicle which drives by using electricity as power, and acquires driving energy by rotating a motor using electricity stored in a battery.

Recently, much research has been conducted on a PBV (Purpose Built Vehicle) based on urban ecomobility, in which a user can freely use a customized service such as a cafe or hospital according to the design, while moving.

In order to modify the body of a PBV according to a user's taste, it is necessary to reduce the number of structures which are directly assembled to the bottom of the body of an existing vehicle.

The lever <NUM> is inserted into one side (left side in <FIG>) of the cage holding part <NUM>, and serves to expand an opening of the cage holding part <NUM>. When the opening of the cage holding part <NUM> is expanded by the operation of the lever <NUM>, the cage insertion part <NUM> inserted into the cage holding part <NUM> may be separated from the cage holding part <NUM>.

In the present invention, the inner surface of the cage holding part <NUM> has a width that decreases toward the inside of the cage body <NUM>, and the outer surface of the cage insertion part <NUM> has a width that decreases toward the outside of the cage body <NUM>.

Therefore, as the inner surface of the cage holding part <NUM> has a width that decreases toward the inside of the cage body <NUM>, and the outer surface of the cage insertion part <NUM> has a width that decreases toward the outside of the cage body <NUM>, the cage insertion part <NUM> may be easily inserted or introduced into the cage holding part <NUM>.

The lever manipulation part 317c is extended from the second lever support part 317b, and pressed to turn the second lever support part 317b, thereby expanding the opening of the cage holding part <NUM>. Referring to <FIG>, when the lever manipulation part 317c is pressed and turned in the clockwise direction, the second lever support part 317b connected to the lever manipulation part 317c is also turned in the clockwise direction to expand the opening of the cage holding part <NUM>. At this time, the protrusion 311a is separated from the insertion hole 313a, and the connected cages <NUM> are separated from each other.

In the present invention, the wire cage <NUM> is made of a plastic material having preset strength and hardness. The preset strength and hardness of the wire cage <NUM> indicate strength and hardness which are set to such an extent that the wire cage <NUM> can connect the battery <NUM> and the side frame <NUM> while supporting the weight of the battery <NUM>, and can be broken when external shock equal to or more than a preset level of shock is transferred from the side frame <NUM>, thereby buffering the shock transferred to the battery <NUM>.

Therefore, in case of a side collision of the vehicle, the wire cage <NUM> may be broken by shock transferred from the side frame <NUM>, and disperse a collision load. As a result, the wire cage <NUM> may reduce the damage to the battery <NUM>, thereby reducing an occurrence of accident such as a fire.

Referring to <FIG>, a chassis frame module for an electric vehicle in accordance with another embodiment of the present invention includes a chassis frame <NUM>, a battery <NUM>, and a wire assembly <NUM>.

In the present invention, the chassis frame <NUM> may be made of a metal or elastic fiber. The chassis frame <NUM> may be made of a light metal or a metal including elastic fiber, and thus improve the strength and hardness of the vehicle and improve the fuel efficiency of the vehicle, while reducing the weight of the vehicle. Examples of the light metal included in the chassis frame <NUM> may include aluminum, magnesium and the like.

The vehicle body is a structure of the vehicle, which is designed to contain and protect mechanical parts, passengers and freight, and has a shape decided according to the use and size of the vehicle or the like.

The rear frame <NUM> serves to connect the rear ends of the side frames <NUM>, and is disposed at the rear (left in <FIG>) of the vehicle body. An extruded material (e.g. aluminum or the like) manufactured through an extrusion method may be used for the rear frame <NUM>.

The wire assembly <NUM> is connected to the side frame <NUM> and the battery <NUM>, and contains a wire <NUM> in an internal space thereof. The wire <NUM> may be contained in the wire assembly <NUM> so as not to be exposed to the outside, which makes it possible to prevent corrosion of the wire <NUM>.

The wire assembly <NUM> is connected to the side frame <NUM> by a fastener <NUM>. The wire assembly <NUM> includes a wire cage <NUM> and a clip <NUM>. The wire cage <NUM> has one side (right side in <FIG>) connected to the side frame <NUM> and the other side (left side in <FIG>) connected to the battery <NUM>. The wire cage <NUM> has an internal space in which the wire <NUM> is contained.

The wire assembly <NUM> is disposed between the side frame <NUM> and the battery <NUM>. The clip <NUM> of the wire assembly <NUM> is coupled to the side frame <NUM>, and the wire cage <NUM> of the wire assembly <NUM> is assembled and fixed to the outer wall of the battery <NUM> with the clip <NUM>.

The wire cage <NUM> includes a cage body <NUM> and a grid part <NUM>. The cage body <NUM> has one side (right side in <FIG>) connected to the side frame <NUM> and the other side (left side in <FIG>) connected to the battery <NUM>, and has an internal space formed therein. The wire <NUM> is inserted and contained in the internal space of the hollow wire cage <NUM>.

The grid part <NUM> is mounted in the internal space of the cage body <NUM>, and formed in a grid shape to divide the space in which a plurality of clips <NUM> are mounted. That is, the grid part <NUM> has a cross-shaped cross-section. The cross-shaped grid part <NUM> may form four divided spaces, and the plurality of clips <NUM> may be mounted in the respective divided spaces. As the divided spaces are formed in the cage body <NUM> by the grid part <NUM>, the plurality of wires <NUM> mounted on the clips <NUM> are separately disposed so as not to overlap each other.

In the present invention, the wire cage <NUM> is made of a plastic material having preset strength and hardness. The preset strength and hardness of the wire cage <NUM> indicate strength and hardness which are set to such an extent that the wire cage <NUM> can connect the battery <NUM> and the side frame <NUM> while supporting the weight of the battery <NUM>, and can be broken when external shock equal to or more than a preset level of shock is applied from the side frame <NUM>, thereby buffering the shock applied to the battery <NUM>.

Therefore, in case of a side collision of the vehicle, the wire cage <NUM> may be broken by shock applied from the side frame <NUM>, and disperse a collision load. As a result, the wire cage <NUM> may reduce the damage to the battery <NUM>, thereby reducing an occurrence of accident such as a fire.

The clip <NUM> is mounted in the wire cage <NUM>, such that the wire <NUM> is seated on the clip <NUM>. The clip <NUM> having the wire <NUM> seated thereon prevents the separation of the wire <NUM>. The clip <NUM> is detachably mounted in the wire cage <NUM>. As the clip <NUM> is detachably mounted in the wire cage <NUM>, the clip <NUM> may be easily assembled to/separated from the wire cage <NUM>, such that an operator can perform repair or replacement.

The clip insertion part <NUM> is mounted on the cage body <NUM> of the wire cage <NUM>. The clip insertion part <NUM> is detachably mounted on the cage body <NUM> of the wire cage <NUM>.

The clip insertion part <NUM> is formed in an arrowhead shape whose size gradually decreases in the insertion direction to the wire cage <NUM>, and made of an elastically deformable material. The clip insertion part <NUM> is formed in an arrowhead shape whose size gradually decreases in the insertion direction to the wire cage <NUM>, and thus easily inserted into the cage body <NUM> of the wire cage <NUM>.

Furthermore, the clip insertion part <NUM> is made of an elastically deformable material. Therefore, the clip insertion part <NUM> is compressed when inserted into the cage body <NUM> of the wire cage <NUM>, and then elastically restored after the insertion into the cage body <NUM> of the wire cage <NUM>. Thus, the clip insertion part <NUM> may be prevented from being separated from the cage body <NUM>.

The clip rod part <NUM> is extended from one side (right side in <FIG>) of the clip insertion part <NUM>, and formed in a rod shape with a preset length. The clip rod part <NUM> connects the clip insertion part <NUM> and the contact surface part <NUM>, and is inserted into a through-hole of the cage body <NUM>.

The contact surface part <NUM> is mounted at an end (right end in <FIG>) of the clip rod part <NUM>, and comes into contact with one surface of the cage body <NUM> of the wire cage <NUM>. The contact surface part <NUM> comes in contact with the one surface of the cage body <NUM> of the wire cage <NUM>, and thus serves as a stopper to restrict the movement of the clip insertion part <NUM> and the clip rod part <NUM>.

The elastic coupling part <NUM> is formed on one side of the contact surface part <NUM>, has a ring shape whose one side (right side in <FIG>) is open, and is elastically coupled to the wire <NUM>. The elastic coupling part <NUM> is made of a metal or plastic material. When the wire <NUM> is inserted into the opening of the elastic coupling part <NUM>, the elastic coupling part <NUM> may be spread. Then, the elastic coupling part <NUM> may be retracted while surrounding the outer surface of the wire <NUM>, and elastically coupled to the wire <NUM>, thereby preventing the separation of the wire <NUM>.

In the chassis frame module for an electric vehicle in accordance with the present invention, the wire <NUM> may be contained in the wire assembly <NUM> which connects the side frame <NUM> and the battery <NUM>. Thus, the space efficiency of the chassis frame module may be improved so that the chassis frame module can be manufactured in a shape proper to the concept of the vehicle.

Furthermore, the wire <NUM> may be contained in the wire assembly <NUM>, which makes it possible to reduce the corrosion of the wire <NUM>, caused by the exposure to the outside.

Furthermore, the wire assembly <NUM> may be interposed between the side frame <NUM> and the battery <NUM>. Thus, in case of a side collision of the vehicle, the wire assembly <NUM> can disperse a collision load and reduce the damage to the battery <NUM>, thereby reducing the occurrence of accident such as a fire.
