Abstract

The invention relates to the field of wheelchair equipment, in particular to a wheelchair with novel brake devices. The wheelchair comprises a frame, front wheels and rear wheels, the front wheels and the rear wheels are mounted on the lower portion of the frame, the brake devices are mounted on the upper portions of the rear wheels and comprise brake shells, the brake shells are mounted on the frame, parking brake strips are arranged in the brake shells and rotatably mounted on the inner walls of the brake shells, and friction wheels are arranged in the brake shells and can vertically move. The wheelchair with the novel brake devices can solve the problem that the moving speed of an existing wheelchair cannot be reduced.

Description

technical field [0001] The invention relates to the technical field of wheelchair equipment, in particular to a wheelchair with a novel braking device. Background technique [0002] As a special medical device, wheelchairs are designed to serve specific groups of people or the elderly, especially for people with limited mobility. It is not only a means of transportation, but more importantly, it can travel and participate in social activities with the help of wheelchairs. . The users of wheelchairs are patients, the disabled, and the elderly. When they use them, they may be themselves or ask someone to take care of them (the general caregivers in our country are middle-aged and elderly people). The places of use are generally outdoors or hospitals. The ground environment is uneven. For example, when there is a slope going downhill, the speed of the wheelchair will be accelerated (with the user's weight and the inertia of the speed), which will pose a safety hazard to the u...
