A wheelchair with high safety performance

Abstract

The invention relates to a wheelchair with high safety performance, including a main body, push handles, two front wheels and two rear wheels, wherein the push handle is arranged on one side of the main body, the front wheels and the rear wheels are arranged below the main body, the rear wheels is arranged between the push handles and the front wheels, two control mechanisms are arranged on the front wheels, two speed limiting mechanisms are arranged on the rear wheels, the control mechanisms are one-to-one corresponding to the front wheels, the speed limiting mechanisms and the rear wheels correspond one by one, the control mechanisms include a lifting plate, a bracket, a level, a rotating shaft, a locking assembly and two power assemblies. Each speed limiting mechanism comprises a detecting assembly, a moving assembly, a connecting assembly and at least two speed limiting assemblies. The detecting assembly comprises a fixed block, a moving block, a guide rod, a first spring, a connecting block and a pressure sensor. The wheelchair with high safety performance prevents a user from falling through the control mechanism, and the speed limiting function is also realized through the speed limiting mechanism.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a wheelchair with high safety performance. Background technique [0002] Medical equipment refers to instruments, equipment, utensils, materials or other items used alone or in combination for the human body, including the required software. Medical equipment is the most basic element of medical treatment, scientific research, teaching, institutions, and clinical disciplines, including professional Medical equipment also includes household medical equipment. Wheelchairs are a kind of medical equipment. Wheelchairs are an important tool for rehabilitation. Wheelchairs are not only a means of transportation for physically handicapped and handicapped people, but more importantly, they enable them to rely on wheelchairs. Get physical exercise and participate in social activities. [0003] When the existing wheelchair travels downward on the slope, the user's body will be tilted forw...

AI Technical Summary

Problems solved by technology

[0003] When the existing wheelchair travels downward on the slope, the user's body will be tilted forward, which is easy to cause the user to fall down. Not only that, but when the existing wheelchair travels downward on the slope, due to inertia, the speed will be faster than normal. Increased travel, reduced safety
