Abstract
The utility model discloses a driving mechanism of an electric wheelchair. The driving mechanism comprises a motor. A small cylindrical gear is fixed on the motor shaft of the motor. The small cylindrical gear is engaged with a large cylindrical gear on an output shaft. A wheelchair wheel is directly mounted on the output shaft. The other end of the motor is provided with a safe brake having a release handle. According to the utility model, the wheelchair wheel is directly mounted on the output shaft so that the efficiency is high, the cost is low, and the electric wheelchair can be hand-operated or pushed.
Description
Technical field
This utility model relates to mechanical field, relates in particular to a kind of electric wheelchair driving mechanism.
Background technology
Wheelchair is the important tool of rehabilitation, and it is not only the walking-replacing tool of limbs the disabled, the more important thing is and makes them by means of wheelchair, carry out physical exercise and participate in social activity.Common wheelchair is generally comprised of by four parts wheelchair frame, wheel, brake and seat.
At present, the public's electric wheelchair driving mechanism is all that motor passes through worm decelerating machine (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.
Utility model content
For the problems referred to above, this utility model provides a kind of electric wheelchair driving mechanism, to solve the problems of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
An electric wheelchair driving mechanism, is characterized in that, comprises motor, on the motor shaft of described motor, is fixed with small cylinder gear, and described small cylinder gear is meshed with the big column gear on an output shaft, and wheelchair wheel is directly installed on output shaft; On the other end of motor, be provided with the safety brake with release lever.
In this utility model, a microswitch is installed on described safety brake, coil and the microswitch of safety brake are electrically connected in series, and microswitch can be stirred in one end of release lever.
In this utility model, described big column gear and small cylinder gear are helical gears.
In this utility model, described big column gear and small cylinder gear are straight spur gears.
Wheelchair wheel of the present utility model is directly installed on output shaft, and efficiency is high like this, cost is low, and electric wheelchair can manually or promote.
Feature of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained and be well understood to.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
For technological means, creation characteristic that this utility model is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth this utility model.
As shown in Figure 1, big column gear 2 is arranged on output shaft 1, be fixed on motor shaft 4 with the small cylinder gear 3 of big column gear 2 phase interlocks (engagement), the other end of motor 5 is provided with the safety brake 6 with release lever 7, and a microswitch 8 is installed on safety brake 6.Wheelchair wheel is directly installed on output shaft.
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 wheelchair self-actuating brake; If need manually, just to move 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.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what in above-described embodiment and description, describe is principle of the present utility model; under the prerequisite that does not depart from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that this utility model requires is defined by appending claims and equivalent thereof.
