Automatic slope speed control mechanism for common wheelchair

Abstract

The invention relates to the technical field of rehabilitation equipment, and discloses an automatic slope speed control mechanism for a common wheelchair. The automatic slope speed control mechanismcomprises two groups of fixed connecting rods and a control main shaft, two groups of mounting supports are fixedly mounted on two sides of the outer surfaces of the fixed connecting rods respectively, and the top ends of the mounting supports are in threaded connection with the interior of the common wheelchair. According to the automatic slope speed control mechanism for the common wheelchair, balancing weights movably connected to the fixed connecting rods in a sleeving mode are arranged so that a locking tooth block can be driven to lock a ratchet wheel to prevent slipping when the wheelchair goes uphill, friction plates can be driven to rub speed reduction disc bodies to provide certain friction braking force when the wheelchair goes downhill, the speed of the wheelchair in the downhill process is reduced, the whole linkage process is autonomously regulated and controlled through the influence of gravity borne by the balancing weights on the slope, manual operation is not needed,the flexibility is high, the controllability is good, and the safety and reliability of the wheelchair on the slope are effectively improved.

Description

technical field [0001] The invention relates to the technical field of health equipment, in particular to a slope automatic speed control mechanism for ordinary wheelchairs. Background technique [0002] As an important means of transportation for the disabled to carry out independent activities, wheelchairs can effectively meet the daily travel activities of the disabled, and carry out physical exercise or participate in social activities. Slopes or long downhill situations, and the existing ordinary wheelchairs mainly rely on the hand of the disabled person to carry out direction and forward control through the rotary wheel, when the disabled person goes out alone and faces the uphill, not only for other It consumes a lot of physical strength, and if you leave the rotary wheel and use the handbrake to brake when going uphill, it is very easy to slip the car and lose control of the direction. When facing downhill due to gravity, the speed of the wheelchair It will graduall...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a slope automatic speed control mechanism for ordinary wheelchairs, which can automatically lock in one direction when going uphill, and can automatically assist braking and deceleration when going downhill, without user's control, and is relatively safe. The advantages of high and good stability solve the problem that the existing ordinary wheelchairs mainly rely on the hands of the disabled to control the direction and forward direction through the rotary wheel. When the disabled go out alone and face uphill, not only It consumes a lot of physical strength, and if the hands leave the rotary wheel and use the handbrake to brake when going uphill, it is very easy to slip the car and lose control of the direction. The speed of the wheelchair will be gradually accelerated, because the user needs to control the direction of the wheelchair by manipulating the rotary wheel with both hands, so he can only use his hands to rub the rotary wheel to control the speed, but cannot use the handbrake to control the speed of the wheelchair, so it is very easy Causes scratches to the user's palm and is difficult to control its speed
