Electric quick-connect device and electric disabled vehicle

Abstract

The invention discloses an electric fast connection device and an electric disabled vehicle. The device comprises a center part. Two opposite ends of the center part is provided with a plug part and an electric transforming mechanism which are used for connecting a to-be-assembled object. The electric transforming mechanism drives the center part to ascend or descend, and drives a locking-releasing mechanism located on the center part to lock / release the plug part with / from a first to-be-connected object. The electric fast connection device has the advantages of being delicate in design and simple in structure. Through the structural design of the electric fast connection device, a hydraulic cylinder is used for driving the integral structure deformation, and driving the locking-releasing mechanism to achieve the fast connection and disconnection with an ordinary wheelchair without the need of any extra tools, the operation can be carried out at any moment and any time. The operation is simple, thus greatly enhancing the connection and disconnection efficiency. Moreover, the electric fast connection device is fixedly connected with the ordinary wheelchair, the possibility of loosening is ruled out, thus the stability and safety of the integral structure are enhanced.

Description

technical field [0001] The invention relates to a quick-connecting device and a disabled vehicle, in particular to an electric quick-connecting device and an electric disabled vehicle. 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 labor-intensive, but also the running speed of the...

AI Technical Summary

Problems solved by technology

[0006] 1. The method of bolt connection has high requirements for bolt fastening. Once the bolt is loose, it will affect the stability of the connection and the safety of driving. The method of bolt connection, whether it is assembly or disassembly, is relatively troublesome. It is time-consuming and labor-intensive, and corresponding tools are required to realize assembly and disassembly. The disassembly conditions are limited, and one-key assembly cannot be realized

[0007] 2. 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 manual. 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;

[0008] 3. 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.
