Auxiliary electric wheelchair device with draw-in and draw-off function

Abstract

The auxiliary electric wheelchair device with draw-in and draw-off function includes one combining unit, one turning and walking unit and one power supply unit. The combining unit includes one joint seat assembly and several cross bar assemblies connected to the joint seat assembly and combined to the hand driven wheelchair; and the turning and walking unit includes one operating rod assembly, one electric wheel assembly, and one link rod assembly. The link rod assembly drives the electric wheel assembly to shift to either one use position or one non-use position. When it is in the non-use position, the electric wheel assembly is over the ground; when it is in the use position, the electric wheel assembly is contacted with ground. The auxiliary electric wheelchair device has simple state transformation and makes it easy for the wheelchair sitter to get on and off.

Description

technical field [0001] The invention relates to an electric device that can be assembled on a manual wheelchair, in particular to an auxiliary electric device for a wheelchair that has a retractable function, can easily change the use state, is more convenient to disassemble and assemble, and is convenient for users to get on and off the wheelchair. Background technique [0002] Wheelchair (Wheelchair) is the main means of transportation for the disabled groups such as the elderly or physically handicapped. The use of wheelchairs can enable these disabled groups to meet their independent moving needs in terms of walking. [0003] According to the source of power supply, it can be roughly divided into two types: manual wheelchairs and electric wheelchairs. The power source of the manual wheelchair is the user's hands to push the hand wheel of the manual wheelchair, and the rear wheel is driven to rotate to achieve the movement of the wheelchair. The electric wheelchair uses ...

AI Technical Summary

Problems solved by technology

[0005] In the use of the aforementioned auxiliary push electric device, there are problems such as the relatively large volume, the complicated disassembly and assembly, and the inability to fold the steering handle, which makes it difficult for the user to get on and off the wheelchair... etc., which reduces the user's purchase and use. will

[0006] This shows that the above-mentioned existing wheelchair auxiliary electric device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
