A battery frame is fixed to a chassis and a battery pack is assembled to the battery frame. The battery frame includes a pair of crossbars and a pair of side bars. The crossbars extend in the vehicle width direction while being spaced apart in the vehicle front-rear direction, and have both ends in the vehicle width direction fixed to the side members. The side bars extend in the vehicle front-rear direction while being spaced apart in the vehicle width direction, and have front ends and rear ends detachably fixed to the crossbars.
First claim
Opening claim text (preview).
What is claimed is: 1. A trailer comprising: a chassis including a pair of side members that is disposed at both ends in a vehicle width direction and that extends in a vehicle front-rear direction, and a pair of cross members that connects front ends and rear ends of the side members and that extends in the vehicle width direction; a wheel pivotally supported by the chassis; an axle of the wheel; a battery pack including a plurality of battery cells and a casing housing the battery cells; and a battery frame fixed to the chassis and to which the battery pack is assembled, wherein the battery frame includes a pair of crossbars extending in the vehicle width direction while being spaced apart in the vehicle front-rear direction, and having both ends in the vehicle width direction fixed to the side members, and a pair of side bars extending in the vehicle front-rear direction while being spaced apart in the vehicle width direction, and having front ends and rear ends detachably fixed to the crossbars, wherein the pair of crossbars are provided rearward of the axle of the wheel such that the pair of crossbars are spaced apart from the axle of the wheel in the vehicle front-rear direction, and wherein the battery pack is electrically disconnected from a drive mechanism that drives the wheel and a regenerative mechanism that regeneratively brakes the wheel. 2. The trailer according to claim 1 , wherein both ends of the crossbars in the vehicle width direction are respectively fixed to the side members via side brackets, each of the side brackets extends downward from a corresponding one of the side members, and a corresponding one of the crossbars is fixed to a lower end of each of the side brackets, and the battery frame is positioned at a position lower than a position of the chassis.
