Stepping rapid connection device and electric wheelchair with same

Abstract

The invention discloses a stepping rapid connection device which comprises a deformable quadrilateral component. The deformable quadrilateral component comprises a fixing frame, a fixing part, an upper connection rod and a lower connection rod. The fixing frame is further provided with a stepping sheet and a handle. One end of the handle is connected with a supporting rod in a pivoted mode, the other end of the supporting rod is arranged at the lower connection rod in a pivoted mode, the handle is further provided with a shifting piece, a driving block is pivoted to the fixing frame and controls a locking part, the handle pushes the driving block, and then the locking part is driven to fix a rear vehicle frame and the fixing frame. According to the technical scheme, design is elaborate, the structure is simple, rapid connection and detaching of a manual wheelchair and an electric traction head can be achieved, and connection efficiency and detaching efficiency are greatly improved; overall connection is firm, no looseness is caused, and the stability and safety of the overall structure are improved.

Description

technical field [0001] The invention relates to a connection device and an electric disabled vehicle, in particular to a stepping quick connecting device and an electric disabled vehicle adopting the stepping quick connecting device. Background technique [0002] Wheelchair is an important tool for rehabilitation. It is not only a means of transportation for physically disabled and handicapped people, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. [0003] Ordinary hand-operated wheelchairs are generally composed of four parts: wheelchair frame, wheels, brake device and seat. On the basis of ordinary hand-operated wheelchairs, hand-operated wheelchairs add hand-operated devices. For example, the subject name is "wheelchair" and the application number is 200920127691.6. What the new patent discloses is exactly a kind of hand-operated wheelchair, and hand-operated wheelchairs are not only l...

AI Technical Summary

Problems solved by technology

[0005] 1. The method of connecting with bolts has high requirements for bolt fastening. Once the bolts are loose, it will affect the stability of the connection and the safety of driving.

[0006] 2. Whether the bolt connection method is assembled or disassembled, the process is relatively cumbersome, and special tools must be used to perform it. Therefore, assembly and disassembly cannot be carried out all the time, and are limited by certain conditions.

[0007] 3. The connecting bracket and the independent power unit are integrated. Once the connecting bracket is damaged, it is not easy to disassemble from the independent power unit, and it is inconvenient to disassemble, maintain and install
