Dynamic start arrangement of power-assisted wheelchair

Abstract

The invention discloses a dynamic starting structure of dynamic auxiliary wheel chair, which consists of motor and starting mechanism in the wheel on two sides of wheel, wherein the user pulls the wheel chair forwards or backwards, which anchors driving disc to rotate to push rotor from deep end to shallow end, when the rotor lies in the shallow region, whose touching disc is pushed out by rotor to trigger switch to move, the motor is started, which outputs auxiliary power for wheel chair.

Description

technical field [0001] The present invention is a power starting structure of a power-assisted wheelchair, especially when a user exerts force to turn a hand push ring, a switch can be triggered to start a motor and output auxiliary power to drive the wheelchair to travel. Background technique [0002] For disabled people with inconvenient mobility, traditional wheelchairs are not only the best means of transportation, but also the best rehabilitation tools; because, when the user uses both hands to move the wheels, the user's arm is provided. Sports and physical rehabilitation; it is worth noting that when the traditional wheelchair is driving on a smooth road, it will not be difficult for the user to drive; however, when the road has a rising slope, it will be difficult for the user It seems to be more strenuous; and when the ascending slope exceeds 15 degrees, it is almost impossible to drive by itself, and it is necessary to rely on the assistance of others to pass; [...

Problems solved by technology

[0004] It is worth noting that, in the aforementioned operation of using the push ring to control the switch and motor actuation, in order to avoid the danger of the motor actuating if the push ring is lightly touched by mistake, the push ring is usually designed to have a function. The actuation stroke, that is, the motor will start to run only after the hand push ring is turned for a certain distance, but the stroke should not be too long, otherwise there will be a slow-moving operation feeling;

[0005] In common designs, sophisticated electronic circuits or mechanisms are used to detect the strength of manpower, so that the power output can be controlled in a timely manner; but relying entirely on sophisticated electronic circuits for motor start-up control, not only the failure rate is high, but also the cost is high;
