The wheelchair comprises a wheelchair frame 1, an upper supporting cross rod 11, a lower supporting cross rod 12, a battery box 2, a clamping part 21, an arc-shaped elastic buckling arm 22, an opening 23, a buckling block 24, a battery module 3, a cover plate 4 and a buckling groove 41.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

Referring to fig. 1-4, in the present embodiment, a side battery box 2 for quick shell disassembly suitable for an electric wheelchair includes a wheelchair frame 1 and two battery boxes 2, wherein the wheelchair frame 1 is formed with symmetrically arranged support rod sets at two side positions below a seat cushion, each support rod set includes an upper support cross rod 11 and a lower support cross rod 12 arranged up and down, and the upper support cross rod 11 and the lower support cross rod 12 are both columns extending in a transverse direction.

In the present embodiment, two battery cases 2 are respectively installed in cooperation with two sets of support rods. The equal shaping of battery case 2 of this embodiment has the chamber that holds that is used for holding placing battery module, and the battery cover is equipped with rather than lock joint complex apron 4, and apron 4 covers on the accent that holds the chamber, promptly, encloses into the airtight cavity that holds battery module jointly through holding chamber and apron 4. The battery case 2 of this embodiment has buckle piece 24 along the accent edge extension shaping that holds the chamber, and the border position shaping of apron 4 has the joint groove 41 that supplies buckle piece 24 to inlay the dress joint mutually, promptly, inlays the dress joint through between buckle piece 24 and the joint groove 41 in order to realize apron 4 detachably lock joint on battery case 2, adopts such mode so that the user can easily change battery module.

In this embodiment, a clamping portion 21 is formed at the upper end portion and the lower end portion of each battery box 2, the two clamping portions 21 of each battery box 2 are respectively in buckling fit with the upper supporting cross bar 11 and the lower supporting cross bar 12, and the distance between the two clamping portions 21 is equal to the distance between the upper supporting cross bar 11 and the lower supporting cross bar 12, wherein the clamping portion 21 of this embodiment is a horizontally long structure with a U-shaped cross section, that is, the clamping portion 21 is a U-shaped arc elastic buckling arm 22, and the arc elastic buckling arm 22 is formed with an opening 23 which is open outwards and is used for the upper supporting cross bar 11 or the lower supporting cross bar 12 to be embedded and fitted, the span between the two ends of the opening 23 is smaller than the diameter width of the upper supporting cross bar 11/the lower supporting cross bar 12, and the upper supporting cross bar 11/the lower supporting cross bar 12 are embedded and clamped by using the elastic deformation characteristic of the arc elastic buckling arm 22, so as to realize the buckling fit between the clamping portion 21 and the, thereby realizing the quick and detachable installation of the battery box 2 on the wheelchair frame 1,
