Abstract
Provided is a driving mechanism for an electric wheelchair. A large cylindrical gear 2 is installed on an output shaft 1, a small cylindrical gear 3 meshed with the large cylindrical gear 2 is fixed to a motor shaft 4, and a safe brake 6 and a brake release handle 7 are installed at the other end of a motor 5. Wheels of the wheelchair are directly installed on the output shaft, and therefore the efficiency is high, the cost is low, and the electric wheelchair can be operated manually or pushed.
Description
Technical field
This utility model relates to a kind of electric wheelchair driving mechanism.
Background technology
At present, the public's electric wheelchair driving mechanism is all that motor passes through worm decelerating machine (the worm speed-down engine efficiency is very low) transmission, and such driving device efficiency is low, cost is high; Although what also have is direct driving, the release lever that do not brake, electric wheelchair cannot manually or promote.
The utility model content
In order to overcome, existing electric wheelchair driving mechanism efficiency is low, cost is high, the shortcoming of can not be manually or promoting, this utility model provides a kind of electric wheelchair driving mechanism, and this device has not only improved efficiency, reduced cost, can also make electric wheelchair manually or promote.
This utility model solves the technical scheme that its technical problem adopts: big column gear 2 is arranged on output shaft 1, with the small cylinder gear 3 of big column gear 2 phase interlocks, be fixed on motor shaft 4, the other end of motor 5 is equipped with safety brake 6 and brake release lever 7, a microswitch 8 is installed on safety brake 6, big column gear 2 is to use helical gears with small cylinder gear 3, also can use straight spur gear.The wheelchair wheel is directly installed on output shaft.
The beneficial effects of the utility model are, electric wheelchair both can manually or be promoted, and improved again efficiency, have reduced cost.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the structural representation of the specific embodiment
In Fig. 1: the 1st, output shaft; The 2nd, the big column gear; The 3rd, small cylinder gear; The 4th, motor shaft; The 5th, motor; The 6th, safety brake; The 7th, the brake release lever; The 8th, microswitch.
The specific embodiment
As shown in Figure 1, big column gear 2 is arranged on output shaft 1, with the small cylinder gear 3 of big column gear 2 phase interlocks, be fixed on motor shaft 4, the other end of motor 5 is equipped with safety brake 6 and brake release lever 7, and a microswitch 8 is installed on safety brake 6.The wheelchair wheel is directly installed on output shaft.
Big column gear 2 is to use helical gears with small cylinder gear 3, also can use straight spur gear.
The coil of safety brake 6 and microswitch 8 are electrically connected in series, and the other end of brake release lever 7 can be stirred and obtain microswitch 8.Like this control system of wheelchair just can perception manually and motoring condition.
When stopping, wheelchair have safety brake to make the wheelchair self-actuating brake; If need manually, just to move the brake release lever, wheelchair just can freely move, and it is manual mode that control system just can perceive, and can suppress electric wheelchair and drive.
Claims (4)
1. an electric wheelchair driving mechanism, by motor, gear, safety brake and brake release lever, formed, it is characterized in that: big column gear (2) is arranged on output shaft (1), be fixed on motor shaft (4) above with the small cylinder gear (3) of big column gear (2) phase interlock, the other end of motor (5) is equipped with safety brake (6) and brake release lever (7).
