Abstract
The utility model relates to an electric wheel chair driven by synchronous belts. The inner sides of wheels on both sides of the wheel chair are respectively installed with large synchronous belt wheels, and a motor transfers the motive power to the wheels through a small synchronous belt wheel, synchronous belts and the large synchronous belt wheels on shafts; and the other end of the motor is installed with a safe brake and a brake release handle. The electric wheel chair dispenses with the worm reduction gearbox, thereby not only increasing the efficiency, but also reducing the cost and the noise; and the electric wheel chair is provided with the safe brake and the brake release handle, thereby being safe and realizing manual and electric push.
Description
Affiliated technical field
This utility model relates to a kind of electric wheelchair, especially a kind of electric wheelchair of synchronous band transmission.
Background technology
At present, the public's electric wheelchair all is that motor passes through worm decelerating machine (the worm speed-down engine efficiency is very low) and passes to wheel, and such driving device efficient is low, cost is high; Though what also have is direct driving, the release lever that do not brake, electric wheelchair cannot manually or promote.
The utility model content
Existing electric wheelchair efficient is low, cost is high in order to overcome, the shortcoming of can not be manually or promoting, this utility model provides a kind of electric wheelchair of synchronous band transmission, and this device has not only improved efficient, reduced cost, and electric wheelchair can manually or be promoted.
The technical scheme that its technical problem that solves this utility model adopts is: the inner ring of the inboard of two wheels of electric wheelchair is equipped with big synchronous pulley respectively, and motor is added in power on the wheel by the small synchronous pulley on the axle, synchronous band, big synchronous pulley; The other end at motor is equipped with safety brake and brake release lever.
The beneficial effects of the utility model are that electric wheelchair both can manually or promote, and had improved efficient again, had reduced cost and noise.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is the structural representation of the specific embodiment.
Among Fig. 1: 1 motor; The 2nd, small synchronous pulley; The 3rd, big synchronous pulley; The 4th, wheel; The 5th, safety brake; The 6th, the brake release lever; The 7th, synchronous band.
The specific embodiment
As shown in Figure 1, be the inboard that big synchronous pulley 3 is positioned on wheelchair 4, small synchronous pulley 2 fixedly is positioned on the axle of motor 1, and motor 1 is fixed on the vehicle frame; The other end of motor 1 is equipped with safety brake 5 and brake release lever 6; Band is enclosed within on big synchronous pulley 3 and the small synchronous pulley 2 synchronously.The power of motor is added on the wheel with big synchronous pulley by small synchronous pulley, synchronous band; When stopping, wheelchair have safety brake to make the wheelchair self-actuating brake; Manual if desired, just move the brake release lever, wheelchair just can freely move.
Claims (1)
1. the electric wheelchair of a band transmission synchronously, constitute by wheelchair frame, wheel, motor, synchronous band, synchronous pulley, battery, controller, it is characterized in that: the inboard of wheelchair two sidecar wheels is equipped with big synchronous pulley respectively, each big synchronous pulley all passes through a band and a small synchronous pulley interlock synchronously, two small synchronous pulleys directly are fixed on respectively on two motor shafts, and the other end of each motor all is equipped with safety brake and brake release lever.
