Abstract
The utility model discloses a battery support of a foldable electric wheelchair, which comprises a first frame, a second frame and a stop element. The first frame is directly pivoted with a pipe fitting of the first side of a foldable electric wheelchair framework, which can not only upwards pivot to a folded position corresponding to the foldable electric wheelchair framework, but pivot to one side of the foldable electric wheelchair framework to a horizontal position, besides, one end of the second frame is pivoted with the first frame, the other end which can be directly pivoted with a pipe fitting of the second side of the foldable electric wheelchair framework can not only upwards pivot to a folded position corresponding to the foldable electric wheelchair framework but pivot to one side to a horizontal position. The stop element is arranged on the foldable electric wheelchair framework to prevent the first frame and the second frame from downwards rotating from the horizontal positions, thereby forming a hollow frame or a recess for supporting batteries. The battery support not only simplifies mounting and dismounting of the batteries, but can save manufacturing cost due to small quantity component and light weight.
