[0048] In the following, reference will be made to Figures 1 to 10 A vehicle body on which a battery 500 is mounted according to an exemplary form of the present disclosure is described.

[0049] A vehicle body equipped with the battery 500 has been developed such that the battery 500 is mounted on a lower portion of the vehicle body to be applied to an electric vehicle or a hybrid electric vehicle and to protect the battery 500 .

[0050] Figure 1 is a perspective view showing a vehicle body 1 equipped with a battery according to an exemplary form of the present disclosure, Figure 2 It is along Figure 1 A cross-sectional view taken along line AA is shown.

[0051] In one form, a vehicle body on which a battery 500 is assembled includes: a lower plate 100 of the vehicle extending in a planar direction and to which the battery 500 is coupled; a door opening / closing device 200 located on a side surface of the lower plate 100 and coupled so that a door 800 of the vehicle can be opened or closed; and a cross member 300 extending in a direction parallel to the transverse direction of the vehicle, coupled to an upper portion or a lower portion of the lower plate 100 and positioned to correspond to the door opening / closing device 200 in the transverse direction.

[0052] like Figure 1 and Figure 2 As shown, the lower panel 100 may be made of a metal material as a panel located under the vehicle, and manufactured by press forming.

[0053] The battery 500 may be coupled to the lower surface of the lower plate 100 by a bolt coupling, and may also be coupled by a coupling method other than the bolt coupling. The battery 500 may be connected to a motor for driving a vehicle to supply power to the motor driving the vehicle.

[0054] The battery 500 may be composed of the battery 500 having various shapes, and a case surrounding the battery 500 is made to protect the battery 500 , and thus the battery 500 may be coupled to the lower plate 100 together with the case.

[0055] The door opening / closing device 200 is mounted on the side surface of the lower panel 100 and connected to the door 800 of the vehicle so that the door 800 of the vehicle can be opened and closed. The door opening / closing device 200 can be operated by the drive of the motor, and the motor can be connected to the battery 500 to receive power. In addition, the door opening / closing device 200 can be connected to the control unit of the vehicle to be operated by the control of the driver of the vehicle.

[0056] The cross member 300 may be located on and coupled to an upper surface or a lower surface of the lower panel 100 , and coupled to a position laterally corresponding to the door opening / closing device 200 .

[0057] Therefore, the cross member 300 can support the side surface of the door opening / closing device 200, thereby suppressing or preventing damage to the battery 500 or explosion of the battery 500 caused by the impact transmitted to the battery 500 due to the door opening / closing device 200 being recessed in the lateral direction of the vehicle during a side collision of the vehicle.

[0058] The vehicle body on which the battery 500 is mounted further includes a side beam 400 extending in a direction parallel to the longitudinal direction of the vehicle and coupled to both sides of the lower panel 100 or both sides of the cross member 300 , and the door opening / closing device 200 is mounted outside the side beam 400 .

[0059] like Figure 1 and Figure 2 As shown, the side member 400 may be coupled to the side surface of the lower panel 100. Therefore, the battery 500 and the side surface of the lower panel 100 may be protected at the time of a side collision of the vehicle.

[0060] In addition, a door opening / closing device 200 of a vehicle may be installed on one side of the side member 400 to open and close a door 800 located on a side surface of the vehicle.

[0061] In addition, a plurality of cross members 300 are coupled to the other side of the side beam 400 , and the cross members are coupled to both sides of the lower panel 100 to couple the side beam 400 , and the cross members 300 may support the side beam 400 to improve the rigidity of the side beam 400 .

[0062] Therefore, when the vehicle collides sideways, the lower panel 100 and the battery 500 within the side member 400 can be protected.

[0063] Figure 4 is a perspective view showing a side member 400 of a vehicle body on which a battery is mounted according to an exemplary form of the present disclosure.

[0064] The side member 400 is coupled around an upper portion or a lower portion of the door opening / closing device 200 .

[0065] like Figure 1 , Figure 2 and Figure 4 As shown, the door opening / closing device 200 can be installed on the outside of the side beam 400, and the top and bottom of the side beam 400 can extend outward and surround the upper and lower parts of the door opening / closing device 200 installed on the outer surface of the side beam, so that the door opening / closing device 200 and the side beam 400 can be coupled to each other.

[0066] Therefore, the side member 400 may protect the door opening / closing device 200 from an external impact applied thereto on the top or bottom of the door opening / closing device 200 .

[0067] Figure 6 is a perspective view showing a battery 500 and a battery holder 600 of a vehicle body on which the battery is mounted according to an exemplary form of the present disclosure.

[0068] The battery-mounted vehicle body further includes a battery bracket 600 extending outward from the battery 500 in the lateral direction such that the battery bracket is coupled to the side member 400 in a state where the battery 500 and the side member 400 are spaced apart from each other in the lateral direction.

[0069] like Figure 2 and Figure 6 As shown, the battery bracket 600 can couple the battery 500 to the side beam 400 and couple the battery 500 and the side beam 400 to be spaced apart from each other. The battery bracket 600 can separate the side beam 400 and the battery 500 from each other.

[0070] Therefore, it is possible to suppress or prevent damage to the battery 500 caused by the door opening / closing device 200 being recessed into the vehicle due to a side collision of the vehicle.

[0071] The door opening / closing device 200 and the battery 500 are positioned so that parts of them overlap each other in the vertical direction of the vehicle.

[0072] like Figure 2 As shown, the door opening / closing device 200 coupled to the side beam 400 can be positioned so that the battery 500 and a predetermined portion overlap each other in the vertical direction of the vehicle through the position of the battery bracket 600, and the portion not overlapping with the battery 500 can be coupled to the cross member 300.

[0073] Therefore, the door opening / closing device 200 can disperse the impact applied to the door opening / closing device 200 by the external impact to the cross member 300 side and the battery 500 side, thereby reducing damage to the battery 500 .

[0074] Figure 3 yes Figure 2 Cross-sectional view of a vehicle after a side collision.

[0075] The battery bracket 600 and the side beam 400 are coupled by penetrating the mounting bolts 610 from the bottom to the top.

[0076] like Figure 2 and Figure 3 As shown, the battery holder 600 and the side beam 400 may be coupled by penetrating from the bottom to the top.

[0077] Therefore, when dented toward the battery 500 side in a side collision, the door opening / closing device 200 rotates around the portion where the battery holder 600 and the side member 400 are coupled, and thus the impact force can be directed toward the cross member 300 .

[0078] Therefore, the impact force transmitted to the battery 500 can be reduced or minimized, thereby minimizing damage to the battery 500.

[0079] Figure 7 is a plan view showing a vehicle body on which a battery is mounted according to an exemplary form of the present disclosure, Figure 8 is a bottom view showing a vehicle body on which a battery is mounted according to an exemplary form of the present disclosure.

[0080] The cross member 300 is penetrated in the vertical direction of the vehicle together with the lower panel 100 and the high voltage battery 500 , and is coupled through the mounting module 700 .

[0081] like Figure 7 and Figure 8 As shown, the battery 500 and the lower plate 100 may be vertically penetrated together with the cross member 300, and the battery 500, the lower plate 100 and the cross member 300 are coupled by the mounting module 700. The mounting module may be coupled by a bolt coupling or by a method other than the bolt coupling.

[0082] Therefore, the coupling force among the battery 500 , the lower panel 100 , and the cross member 300 may be improved, and the noise from the road surface and the vibration or noise generated by the lower panel 100 , the battery 500 , and the cross member 300 may be reduced.

[0083] Figure 5 1 is a perspective view showing a first exemplary form of a door opening / closing device 200 in a vehicle body on which a battery is mounted according to an exemplary form of the present disclosure.

[0084] The door opening / closing device 200 is provided with a slide rail 210, and opens and closes a door 800 of a vehicle by sliding the door in a longitudinal direction of the vehicle.

[0085] The slide rail according to the first exemplary form of the present disclosure may be mounted on the side beam 400, and the vehicle door 800 may be opened along the slide rail. The motor may be mounted on the slide rail and connected to the vehicle door 800 to be operated so that the vehicle door 800 is opened and closed along the direction in which the slide rail extends, and the side member may be positioned so that the position of the motor of the door opening / closing device 200 corresponds to the position when the vehicle door 800 is closed, and thus may be coupled to the side beam 400.

[0086] Multiple door opening / closing devices 200 such as Fig.10 The plurality of doors 800 are installed as shown, and are opposed to each other in the front-rear direction of the vehicle and slide to be opened and closed.

[0087] A plurality of vehicle doors 800 may be mounted on the door opening / closing device 200 , and the plurality of vehicle doors 800 face each other and open to both sides thereof. A plurality of cross members 300 may be located at positions where the plurality of door opening / closing devices 200 are located, respectively, and coupled to the side beam 400 .

[0088] Therefore, even if multiple door opening / closing devices 200 are installed, the door opening / closing devices 200 can all be supported, thereby suppressing or preventing damage to the battery 500 caused by the protrusion of the door opening / closing devices 200 toward the battery 500 during a side collision of the vehicle.

[0089] Fig. 9 1 is a perspective view showing a second exemplary form of the door opening / closing device 200 in the vehicle body on which the battery 500 is mounted according to the exemplary form of the present disclosure.

[0090] The door opening / closing device 200 is provided with a swing hinge portion 220 so that a door 800 of a vehicle swings in the front-rear direction of the vehicle and opens and closes.

[0091] like Fig. 9 As shown, a door opening / closing device 200 according to a second exemplary form of the present disclosure includes a swing hinge portion that opens to the outside of the vehicle, so that a vehicle door 800 can swing and open around the axis of the swing hinge portion in the front-rear direction of the vehicle.

[0092] While particular exemplary forms of the present disclosure have been shown and described, it will be apparent to those skilled in the art that various improvements and changes can be made to the present disclosure without departing from the technical spirit of the present disclosure.
