Abstract

The invention discloses a rear wheel supporting frame structure of an electric wheelchair. The rear wheel supporting frame structure of the electric wheelchair is characterized by comprising a first rear support plate, a second rear support plate, a third rear support plate, a fourth rear support plate and a fifth rear support plate. A third installation hole where a supporting pipe can penetrate is formed in the front end of the first rear support plate. The supporting pipe penetrates through the third installation hole and then is fixed to the first rear support plate. Two extending plates extend backwards from the first rear support plate, so that the first rear support plate is in a V shape. Rear wheels are arranged at the rear ends of the two extending plates. The supporting pipe serves the supporting point. The two extending plates extending backwards to the left and right sides serve as the installation points of the rear wheels, a beautiful design effect is realized, and a big enough space is provided for installation of a storage battery. The bearing strength and the anti-deformation capacity of the first rear support plate are improved through the second rear support plate, the third rear support plate, the fourth rear support plate and the fifth rear support plate. Thus, the bearing strength of the rear wheel supporting frame is improved, and the design looks more beautiful.

Description

technical field [0001] The invention relates to a rear wheel support structure of an electric wheelchair. Background technique [0002] The traditional electric wheelchair is based on the manual wheelchair, superimposed the power drive device, controller, battery and other components, transformed and upgraded, and the manual operation of the controller can drive the wheelchair to complete forward, backward, steering, lying flat, etc. Functional operation provides a convenient and fast way of action for the elderly and the disabled. However, the structural strength of the bracket of the manual wheelchair is relatively weak. In the case of bearing heavy motors and batteries, its bearing capacity is weak and the structure is easily damaged. Therefore, it is the problem to be solved by the present invention to design a new type of electric wheelchair rear wheel support structure with high structural strength and beautiful appearance. SUMMARY OF THE INVENTION [0003] The pur...
