Embodiment 1

[0043] Such as figure 1 As shown, this embodiment provides a folding wheelchair, which is a foldable wheelchair, which can be used normally when unfolded, and has the characteristics of easy operation, small folding volume, and convenient transportation and storage when folded. The folding wheelchair includes a base frame 1 , a seat frame 2 , a folding mechanism 3 , a locking mechanism 4 and a support member 5 .

[0044] The folding mechanism 3 is rotatably arranged relative to the bottom frame 1 and the seat frame 2, and can be linked to approach or move away from the bottom frame 1 and the seat frame 2, and then the bottom frame 1, the seat frame 2 and the folding mechanism 3 constitute the frame of the folding wheelchair. The frame 1 and the seat frame 2 are frame-shaped, the seat frame 2 is the seat of the folding wheelchair, the bottom frame 1 is set under the seat frame 2 to carry and support the rest of the components, and the folding or unfolding of the folding mechani...

Abstract

The invention relates to a foldable wheelchair. The foldable wheelchair comprises a bottom frame, a seat frame, a folding mechanism, a locking mechanism and a support unit, wherein the folding mechanism is arranged rotatably relative to the bottom frame and the seat frame to drive the bottom frame and the seat frame to move close to or away from each other via linkage; the support unit is arrangedamong the bottom frame, the seat frame and the folding mechanism for supporting the expanded state of the folding mechanism; the locking mechanism is used for locking the support unit, when the locking mechanism locks the support unit, the folding mechanism can maintain an expanded state, and when the locking mechanism unlocks the support unit, the folding mechanism can be folded. The componentsof the foldable wheelchair are connected through rotating shafts and linked with one another; by controlling rotation of the support unit, the foldable wheelchair can be controlled to expand or fold and is convenient to operate when being folded; meanwhile, the foldable wheelchair is mainly folded up and down, and due to the fact that the components are foldable, can be folded forth and back to greatly reduce the folded size, thereby being convenient to carry or transport and reducing space occupied during storage.

Description

technical field [0001] The invention relates to the field of wheelchairs, in particular to folding wheelchairs. Background technique [0002] Wheelchairs are devices that help people with disabilities to move and move. Although general wheelchairs provide the convenience for users to carry out medium and long-distance activities, they take up a lot of space when they are stored and stored. [0003] At present, folding wheelchairs are used to solve the problem of large storage space, which is convenient for users or caregivers to carry and carry the wheelchairs. [0004] The existing folding wheelchair mainly has the following defects: [0005] 1) The folding method is basically to fold left and right, and the occupied area after folding and the volume of the wheelchair after folding are still too large, which makes it inconvenient to carry and transport the wheelchair. [0006] 2) The steps of folding and opening are too complicated and inconvenient to operate. Contents ...
