Abstract
The utility model discloses a gear clutch device of an electrically propelled wheelchair. The gear clutch device of the electrically propelled wheelchair comprises a motor (1), a composite gear (2), a clutch handle (3), a shaft output gear (4), a shaft output spring (5) and a shaft output rod (6), wherein the shaft output gear (4) is arranged on the shaft output rod (6), the motor (1) drives the composite gear (2) to rotate, the composite gear (2) is meshed with the shaft output gear (4) when the clutch handle (3) is in an initial position, the composite gear (2) drives the shaft output gear (4) to rotate, so as to drive the shaft output rod (6) to rotate and push the electrically propelled wheelchair to advance and retreat, and the clutch surface of the cultch handle (3) is set to be an involute curved surface. The clutch device of the electrically propelled wheelchair disclosed by the utility model is simple in structure and easy to operate; and the involute curved surface clutch surface is adopted, so that transmission is stable, and abrasion of the clutch handle is less.
Description
Technical field
This utility model relates to a kind of gears to engage and disengage device, and concrete is a kind of electric wheelchair gears to engage and disengage device.
Background technology
The arrangement of clutch of electric wheelchair has a lot, majority is the drive connection adopted between complicated arrangement of clutch change gear, also there is the clutch handle of employing to shift out going out shaft gear, clutch handle is right angle and obtuse angle with the contact surface that goes out shaft gear, such transmission is not steady, and easily cause the clutch handle serious wear, affect the service life of arrangement of clutch.
The utility model content
In order to solve the above-mentioned technical problem existed in prior art, this utility model provides a kind of electric wheelchair gears to engage and disengage device, comprise: motor, built-up gear, clutch handle, go out shaft gear, shaft spring, output shaft lever, describedly go out shaft gear and be arranged on output shaft lever, when clutch handle during in initial position, described built-up gear and go out the shaft gear engagement.
Further, after described clutch handle rotates 90o, describedly go out shaft gear and built-up gear is thrown off.
Further, after unclamping described clutch handle, the shaft reset gear, and built-up gear meshes again.
Further, the interface of described clutch handle is set to involute surface.
Electric wheelchair gears to engage and disengage apparatus structure of the present utility model is simple, easy to operate, and uses involute surface interface stable drive, and the clutch handle wearing and tearing are little.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of electric wheelchair gears to engage and disengage device clutch handle of the present utility model in initial position;
Fig. 2 is the schematic diagram after this electric wheelchair gears to engage and disengage device clutch handle rotates counterclockwise 90o.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, electric wheelchair gears to engage and disengage device of the present utility model comprises: motor 1, built-up gear 2, clutch handle 3, go out shaft gear 4, shaft spring 5, output shaft lever 6, motor 1 drives built-up gear 2 and rotates, built-up gear 2 and go out shaft gear 4 engagements, going out shaft gear 4 is arranged on output shaft lever 6, now, clutch handle 3 is in initial position, built-up gear 2 and go out shaft gear 4 engagements, built-up gear 2 drives out shaft gear 4 and rotates, rotate thereby drive output shaft lever 6, promote the forward-reverse of electric wheelchair.
As shown in Figure 2, stir clutch handle 3, clutch handle 3 with go out the interface that shaft gear 4 contacts and promote out shaft gear 4 moving axially along output shaft lever 6, after clutch handle 3 rotates 90o, going out shaft gear 4 moves to while throwing off with built-up gear 2, go out shaft gear 4 and can not driven by motor 1, mobile thereby electric wheelchair stops.After unclamping clutch handle 3, due to shaft spring 5 elastic reactions, go out shaft gear 4 and reset, and built-up gear 2 meshes again.The interface of clutch handle 3 is designed to involute surface.
Shown in the above and figure is only preferred implementation of the present utility model.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from principle of the present utility model, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
Claims (4)
1. an electric wheelchair gears to engage and disengage device, comprise: motor (1), built-up gear (2), clutch handle (3), go out shaft gear (4), shaft spring (5), output shaft lever (6), describedly go out shaft gear (4) and be arranged on output shaft lever (6), it is characterized in that: when described clutch handle (3) during in initial position, described built-up gear (2) and go out shaft gear (4) engagement.
2. electric wheelchair gears to engage and disengage device as claimed in claim 1 is characterized in that: after described clutch handle (3) rotates 90o, describedly go out shaft gear (4) and built-up gear (2) disengagement.
