Example Embodiment

[0028] Example one:

[0029] See figure 1 , figure 2 , A wheelchair with a new type of brake device, which includes a frame 3 and a front wheel 7 and a rear wheel 6 mounted on the lower part of the frame 3; a brake device 4 is installed above the rear wheel 6; the brake device 4 includes a brake housing 43, The brake housing 43 is installed on the frame 3, a parking brake bar 44 is provided in the brake housing 43, and the parking brake bar 44 is rotatably installed on the inner wall of the brake housing 43; a friction wheel 45 is provided in the brake housing 43, and the friction wheel 45 can Achieve up and down movement; the friction wheel 45 moves down and contacts the rear wheel 6, generating resistance, which reduces the travel speed of the rear wheel 6, and can adjust the up and down position of the friction wheel 45 to get the travel speed you want; the friction wheel 45 does not Affects the work of the parking brake 44. When the parking brake is required, the parking bra...

Example Embodiment

[0038] Embodiment two:

[0039] See figure 2 , Figure 4 The brake device 4 in this embodiment can be installed on a four-wheeled vehicle, which is another usage based on the first embodiment. The technical content disclosed in the first embodiment will not be described repeatedly, and the content disclosed in the first embodiment also belongs to The content disclosed in this embodiment; the brake device 4 of the present invention can be used on other vehicle models, and the present invention will not list them one by one, and all belong to the content disclosed in the present invention.

[0040] Compared with the prior art, the present invention has the following advantages:

[0041] 1. The brake device 4 is installed above the rear wheel of the present invention; the brake device 4 includes a brake housing 43, which is installed on the frame 3, and a parking brake bar 44 is arranged in the brake housing 43. The parking brake bar 44 is rotatable Installed on the inner wall of the...

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...
