FIG. DETAILED DESCRIPTION OF THE INVENTION

[0017] Embodiment Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the invention according to the claims is not limited to the following embodiments. Furthermore, not all of the configurations described in the embodiments are necessarily essential means for solving the problems. For clarity of explanation, the following description and drawings have been omitted and simplified as appropriate. In each drawing, the same elements are given the same reference numerals, and duplicate explanations are omitted as necessary.

[0018] (Description of the vehicle undercarriage according to the embodiment) Fig. 1 is a cross-sectional view of a vehicle lower structure according to an embodiment. Fig. 2 is a schematic diagram of a battery pack, an impact absorbing member, and a reinforcing member according to an embodiment. The vehicle lower structure according to an embodiment will be described with reference to Figs. 1 and 2. Here, the vehicle is, for example, an electric vehicle powered by electricity or a hybrid vehicle powered by electricity and fossil fuels.

[0019] 1, the vehicle includes, in its lower structure, an impact absorbing member 101, a reinforcing member 102, and a battery pack 103. The impact absorbing member 101 is fastened to the reinforcing member 102 using a fastening member 108.

[0020] As shown in Fig. 1, the shock absorbing member 101 is disposed on the lower and side surfaces of the interior of the vehicle. The shock absorbing member 101 deforms when the vehicle receives an impact, such as a side collision, to protect the internal structure of the vehicle. As shown in Fig. 2, the shock absorbing member 101 of this embodiment is disposed on the side surface of the battery pack storage space to protect the battery pack 103, and deforms in response to an impact from the side of the vehicle.

[0021] 1, the reinforcing member 102 is a member that reinforces the housing of the battery pack 103 from the underside of the vehicle. Therefore, the reinforcing member 102 is disposed below the storage space for the battery pack 103. The reinforcing member 102 also has an area that protrudes from the storage space for the battery pack 103.

[0022] The battery pack 103 is a power source that drives the vehicle. The battery pack 103 is arranged in the center and bottom of the vehicle. By being arranged in the center and bottom of the vehicle, the battery pack 103 provides stability and safety to the center of gravity of the vehicle.

[0023] Here, the side surface 104 of the impact absorbing member, the side surface 105 of the reinforcing member, the lower surface 106 of the impact absorbing member, and the upper surface 107 of the reinforcing member are defined based on the top, bottom, and side surfaces of the vehicle.

[0024] At this time, side surface 105 of the reinforcing member has a portion that contacts side surface 104 of the impact absorbing member. Furthermore, upper surface 107 of the reinforcing member has a portion that contacts lower surface 106 of the impact absorbing member. With this structure, even if an impact is applied to the side of the vehicle, impact absorbing member 101 does not rotate and transmits stress to reinforcing member 102. Therefore, reinforcing member 102 can deflect the load applied from impact absorbing member 101 to battery pack 103.

[0025] An upper surface 107 of the reinforcing member is fastened to a lower surface 106 of the shock absorbing member by a fastening member 108. The fastening member 108 is formed of, for example, a bolt and a nut. In this way, the reinforcing member 102 is firmly fixed to the shock absorbing member 101.

[0026] (Description of Reinforcing Member According to the Embodiment) 3 is a schematic diagram of the reinforcing member and the fastening member as seen from the side of the vehicle according to the embodiment. The reinforcing member according to the embodiment will be described with reference to FIG.

[0027] As shown in FIG. 3, the reinforcing member 102 according to the embodiment includes a first reinforcing member 102a, a second reinforcing member 102b, and a third reinforcing member 102c. As shown in FIG. 3, the first reinforcing member 102a and the second reinforcing member 102b have a wave-like structure along the longitudinal direction of the vehicle. This structure further strengthens the reinforcing member 102 against impacts from the side of the vehicle. The third reinforcing member 102c is arranged to define the contour of the lower surface of the reinforcing member 102.

[0028] Furthermore, the first reinforcing member 102a is fastened to the shock absorbing member 101 using a first fastening member 108a. Furthermore, the second reinforcing member 102b is fastened to the shock absorbing member 101 using a second fastening member 108b. The third reinforcing member 102c is fastened to the shock absorbing member 101 using the first fastening member 108a. With this structure, the first reinforcing member 102a, the second reinforcing member 102b, and the third reinforcing member 102c are firmly fixed to the shock absorbing member 101.

[0029] The first fastening member 108a and the second fastening member 108b are, for example, a bolt and a nut. The nut is disposed on the impact absorbing member side, but the positions of the bolt and the nut may be reversed. The positions of the bolt and the nut may be determined to facilitate assembly according to the vehicle assembly work.

[0030] The present invention is not limited to the above-described embodiment, and can be modified as appropriate within the scope of the invention. [Explanation of symbols]
