Abstract
The invention relates to the technical field of electric wheelchair equipment, in particular to a hub fast clutch device for an electric wheelchair. The hub fast clutch device comprises a clutch device body which comprises a motor arranged on the electric wheelchair. A spindle nose at one end of the motor is provided with an electromagnetic brake, and a hub sleeves an output shaft at the other end of the motor. Balls are arranged in the middle in the hub, and the hub is positioned on the output shaft of the motor through the balls. A clutch hand wheel is arranged in an opening in the outer side of the hub and provided with a cavity. A fixing screw is inserted into the clutch hand wheel from the middle of the outer lateral face of the clutch hand wheel, and the body of the fixing screw is penetratingly inserted into the output shaft of the motor and fixed in the same. An end-face flat key is arranged on the left lateral face of the clutch hand wheel, and the clutch hand wheel is meshed with the output shaft of the motor through the end-face flat key. A compression spring sleeves the part, in the cavity of the clutch hand wheel, of the body of the fixing screw. The hub fast clutch device for the electric wheelchair has the advantages that an electric state and a manual state can be switched freely through the meshed state or the separated state of the clutch hand wheel, and the hub fast clutch device is convenient to use.
Description
Technical field
The present invention relates to electric wheelchair equipment technical field, be specifically related to a kind of electric wheelchair wheel hub quick clutch device.
Background technology
Electric wheelchair is gone on a journey for handicapped people.The electric wheelchair now commercially sold, its output shaft is directly connected with wheel hub, function singleness, and cost is high.In addition traditional electric wheelchair can not conveniently freely switch between electronic and manual, when at fortuitous event, electric wheelchair occurs that electric power is not enough, or when not having electricity, cause having no idea to switch to manual mode because its output shaft and wheel hub are directly connected, when being set to manual, promote whole electric wheel-chair vehicle, can seem very difficult, thus affect the trip of handicapped people.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, there is provided a kind of structure simple, a kind of electric wheelchair wheel hub quick clutch device reasonable in design, easy to use, it adopts wheel hub and machine output shaft to be located by ball, be provided with the clutch handwheel of end face flat key, it has can be engaged or released state by clutch handwheel, and freely switches electronic and manual mode, thus is convenient for people to use.
A kind of electric wheelchair wheel hub quick clutch device of the present invention, it comprises arrangement of clutch body, described arrangement of clutch body comprises one and is arranged on motor on electric wheelchair, this motor one end spindle nose arranges an electromagnetism stop, a sheathed wheel hub on this motor other end output shaft, in this wheel hub, middle part is provided with ball, is positioned on the output shaft of motor by ball; Arrange a clutch handwheel in hub mouth outside described wheel hub, this clutch handwheel is provided with cavity, plugs a standing screw in this clutch handwheel in the middle part of its lateral surface, and the body of rod of this set bolt bar interts the output shaft internal fixtion to motor; The left surface of described clutch handwheel is provided with end face flat key, is engaged with the output shaft of motor by end face flat key; A sheathed Compress Spring on the body of rod of described standing screw in clutch handwheel cavity.
After adopting said structure, beneficial effect of the present invention is: a kind of electric wheelchair wheel hub quick clutch device of the present invention, it adopts wheel hub and machine output shaft to be located by ball, be provided with the clutch handwheel of end face flat key, it has can be engaged or released state by clutch handwheel, and freely switch electronic and manual mode, thus be convenient for people to use.

[detailed description of the invention]
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples wherein and explanation are only used for explaining the present invention, but not as a limitation of the invention.
As shown in Figure 1, a kind of electric wheelchair wheel hub quick clutch device described in this detailed description of the invention, it comprises arrangement of clutch body, described arrangement of clutch body comprises one and is arranged on motor 2 on electric wheelchair, this motor 2 one end spindle nose arranges an electromagnetism and stops 1, a sheathed wheel hub 4 on this motor 2 other end output shaft 3, in this wheel hub 4, middle part is provided with ball 5, is positioned on the output shaft 3 of motor 2 by ball 5; Arrange a clutch handwheel 6 in hub mouth outside described wheel hub 4, this clutch handwheel 6 is provided with cavity, plugs a standing screw 8 in this clutch handwheel 6 in the middle part of its lateral surface, and the body of rod of this set bolt bar 8 interts output shaft 3 internal fixtion to motor 2; The left surface of described clutch handwheel 6 is provided with end face flat key, is engaged with the output shaft of motor by end face flat key; A sheathed Compress Spring 7 on the body of rod of described standing screw 8 in clutch handwheel 6 cavity.
As shown in Figure 2, clutch handwheel pulls out by the present invention, then rotates 90 degree, can realize clutch handwheel and " engage-be separated " action with the output shaft of motor.
As shown in Figure 3, a place is clutch handwheel is the state engaged with motor output shaft; The end face flat key of clutch handwheel, is connected the output shaft of motor with wheel hub, connected by the end face flat key of clutch handwheel, and the wheel that the moment of torsion that motor exports can be delivered to electric wheelchair drives wheelchair, and this is that we are commonly called as " electric model ".
As shown in Figure 4, b place is clutch handwheel is the state be separated with motor output shaft; During use, clutch handwheel is under engagement, clutch handwheel is pulled out and 90-degree rotation, make the end face flat key on clutch handwheel, be separated with electronic output shaft, wheel hub three simultaneously, wheel hub now on wheelchair is separated with motor output shaft, and wheelchair wheel can freely be rotated, and this is that we are commonly called as " manual mode ".
The present invention, arranges clutch handwheel, when when engagement: electric machine rotation, drives wheel hub to rotate together; When released state: motor output shaft is motionless, wheel hub can freely rotate.
A kind of electric wheelchair wheel hub quick clutch device of the present invention, it adopts wheel hub and machine output shaft to be located by ball, be provided with the clutch handwheel of end face flat key, it has can be engaged or released state by clutch handwheel, and freely switch electronic and manual mode, thus be convenient for people to use.
The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
