A detachable electric disabled vehicle

Abstract

The invention discloses a detachable electric vehicle for the handicapped. The vehicle comprises an electric traction head and a hand cranking wheelchair which are detachably assembled together. In the release state, a direction wheel of the electric traction head and universal wheels and rear wheels of the hand cranking wheelchair are located on the same plane; in the locking state, the direction wheel of the electric traction head and the rear wheels are located on the same plane, and the horizontal plane where the universal wheels are located is higher than the horizontal plane where the direction wheel and the rear wheels are located. The vehicle is ingenious in design and simple in structure, in the release state, the wheelchair can be normally used, in the locking state, the universal wheels can be lifted up and get away from the ground, and therefore no abrasion is generated in the running process, and the normal running function of the wheelchair is guaranteed through normal manual running of the wheelchair after detachment; on the other hand, the universal wheels suspended in the air will have no resistance on driving, a user can control the direction more easily, design is more humanized, and driving safety and driving stability are improved.

Description

technical field [0001] The invention relates to an electric disabled vehicle, in particular to an electric disabled vehicle that can be quickly connected and disassembled. 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] A hand-operated wheelchair is generally composed of four parts: a wheelchair frame, a steering wheel, a brake device and a seat. On the basis of a hand-operated wheelchair, a hand-operated device is added to the hand-operated wheelchair. For example, the subject name is "wheelchair" and the application number is 200920127691.6. What the patent discloses is exactly a kind of hand-operated wheelchair, and the hand-operated wheelchair is not only labor-intensive, but also the running speed of the whe...

AI Technical Summary

Problems solved by technology

[0005] 1. When assembled together, the universal wheel, the rear wheel of the wheelchair and the steering wheel are all on the ground. Since the output power of the independent power device is relatively large, the running speed of the electric wheelchair is much higher than that of the hand crank. At present, the electric wheelchair does not need the universal wheel to adjust the direction, so the wear of the universal wheel is accelerated under the fast running state, and even the universal wheel is damaged and invalid. When it is disassembled into an ordinary wheelchair, it cannot be used normally, which affects the use of ordinary wheelchairs performance;

[0006] 2. Although the universal wheel can change direction according to the control of the steering wheel at any time, it will more or less produce certain resistance, which will affect the user's control of the steering wheel. Seriously, once the universal wheel is suddenly blocked or the direction is not changed in time If the situation is different, it is easy for the user to be unable to control the direction of the steering wheel, resulting in accidents, etc., and there are certain potential safety hazards.

[0007] 3. The structure of the independent power unit that can control the direction is complex and unsightly. The motor is exposed, and its operation is easily affected by external factors.
