On both sides under a floor of an electric vehicle, side members are provided, each in a closed cross sectional shape. Collars and the like are provided in the side members. On a lower side of a lower wall of each of the side members, cross members which are fixed by using the collars or the like are provided. Between the side members on both sides, a main battery is provided and supported by the cross members. In the vicinity of a lower side of a doorway of the electric vehicle, a cutout part is formed such that a height of a portion of an upper wall of the side member is relatively lowered. On an upper surface of the cutout part, a reinforcing member is provided. A ramp passes through a space on an upper side of the cutout part.

Vehicle structure

A vehicle frame structure includes a pair of rear side members extending along a length of a vehicle in a lower part of the vehicle, and a first cross member coupling the pair of rear side members. The first cross member includes an intermediate member and a pair of coupling members. The intermediate member extends along a width of the vehicle at a location further downward with respect to the rear side members and is located under a motor unit. The pair of coupling members respectively extend downward or diagonally downward from the respective side members toward the opposite ends of the intermediate member.

Vehicle frame structure

The frame of a vehicle includes side rails disposed on the respective left and right sides of the vehicle and extending along the longitudinal direction of the vehicle, a lower cross member connected to the end portions of the side rails and extending along the lateral direction of the vehicle, an upper cross member positioned above the lower cross member and extending parallel to the lower cross member, vertical members extending in the vertical direction of the vehicle on the respective both end portions of the lower cross member and of the upper cross member, to be connected to the lower cross member and the upper cross member; and side members connected to the upper cross member, and extending on the respective right and left sides of the vehicle from the upper cross member to a side opposite from the side rails along the longitudinal direction of the vehicle.

Frame of vehicle

Provided is a vehicle lower-part structure including: a pair of center side members; a main battery that is arranged between the pair of center side members; a support cross member connecting the pair of center side members and supporting a front end of the main battery from below; a pair of support brackets that protrude toward a center in a vehicle width direction from the pair of center side members at positions closer to a rear other end with respect to the support cross member, and support the main battery; and a cable drawn out from the main battery.

Vehicle lower-part structure

Provided is a vehicle lower-part structure including a pair of center side members arranged under a floor of a vehicle; a first cross member and a second cross member connecting the pair of center side members; a main battery arranged in an underfloor space; one or more support plates arranged at a corner of the underfloor space; and a water tank placed on the support plate, in which the support plate is connected to both the center side member and the first or second cross member and connects the two.
