Description
Technical field
This utility model belongs to electric wheelchair field, relates to a kind of convenient electric wheelchair of controlling.
Background technology
Generally there are two handles at the rear portion of electric wheelchair, and entourage carries out electric wheelchair motion by these two handles, but the control of electric wheelchair all concentrates on the controller of wheelchair at present, and by wheelchair, user controls, and entourage can not control.Therefore, need entourage to control electric wheelchair for the user of confusion or uncontrollable own behavior, still, the design of electric wheelchair inconvenient entourage's control in prior art.
Therefore, need a kind of convenient electric wheelchair of controlling to address the above problem.
Utility model content
Utility model object: this utility model is inconvenient to control the defect of electric wheelchair for entourage in prior art, provides a kind of convenient electric wheelchair of controlling.
Technical scheme: for solving the problems of the technologies described above, the convenient electric wheelchair of controlling of the present utility model adopts following technical scheme:
A convenient electric wheelchair of controlling, the rear portion of described electric wheelchair is provided with handle, on described handle, is provided with control device.
Further, described control device comprises handle signal pickup assembly, is provided with described handle signal pickup assembly on each described handle, and described handle signal pickup assembly is foil gauge or push-pull effort sensor.By install foil gauge or push-pull effort sensor additional on the handle of electric wheelchair, be applied to the power on electric wheelchair handle by perception entourage, after microcontroller is processed, be converted to the driving signal of electric wheelchair motor, drive electric wheelchair to complete to advance, retreat, turn left, right-hand rotation, braking etc.
Further, the number of each described the above foil gauge of handle is four.Four foil gauges are set on each handle, and foil gauge is circumferentially evenly distributed along handle.
Further, four described foil gauges be separately positioned on described handle directly over, under, left side and right side.The convenient user that gathers is applied to the power on handle.
Further, described wheel-chair control device also comprises amplifying circuit, signal conditioner, A/D conversion equipment and signal processing apparatus, described handle signal pickup assembly, amplifying circuit, signal conditioner, A/D conversion equipment are connected successively with signal processing apparatus, described electric wheelchair comprises driving device, and described signal processing apparatus connects described driving device.
Further, described amplifying circuit is Wheatstone bridge.
Further, described signal processing device is set to microprocessor.
Utility model principle: the benefit of the method is that entourage can be by study, carrying out when wheel chair sport as gone up a slope or when descending, control system is controlled the moment of torsion of driving wheel automatically after treatment according to power suffered on handle, thereby reaches the effect of power-assisted.
Beneficial effect: the convenient electric wheelchair structure of controlling of the present utility model is simple, only need control device be set in the handle position at wheelchair rear portion, just can greatly save wheelchair entourage's strength.
Accompanying drawing explanation
Fig. 1 is the structural representation of the convenient electric wheelchair of controlling of the present utility model;
Fig. 2 is the structural representation of wheel-chair control device;
Fig. 3 is the schematic flow sheet of wheel-chair control device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate this utility model, should understand these embodiment and only be not used in restriction scope of the present utility model for this utility model is described, after having read this utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
Refer to shown in Fig. 1 and Fig. 2, the utility model discloses a kind of convenient electric wheelchair of controlling, the rear portion of electric wheelchair is provided with handle 1, on handle 1, is provided with control device.Wherein, control device comprises handle signal pickup assembly, on each handle 1, is provided with handle signal pickup assembly, and handle signal pickup assembly is foil gauge or push-pull effort sensor.On each handle 1, the number of foil gauge is four.Four foil gauges are set on each handle 1, and foil gauge is circumferentially evenly distributed along handle 1.Four foil gauges be separately positioned on handle 1 directly over, under, left side and right side.The convenient user that gathers is applied to the power on handle 1.By installing foil gauge or push-pull effort sensor on the handle 1 at electric wheelchair additional, be applied to the power on electric wheelchair handle 1 by perception entourage, after microcontroller is processed, be converted to the driving signal of electric wheelchair motor, drive electric wheelchair to complete to advance, retreat, turn left, right-hand rotation, braking etc.
Wheel-chair control device also comprises amplifying circuit, signal conditioner, A/D conversion equipment and signal processing apparatus, handle signal pickup assembly, amplifying circuit, signal conditioner, A/D conversion equipment are connected successively with signal processing apparatus, electric wheelchair comprises driving device, signal processing apparatus connecting drive device.Amplifying circuit is Wheatstone bridge.Signal processing device is set to microprocessor.Wherein, signal conditioner carries out Filtering Processing to the signal of amplifying circuit.
In the time using wheel-chair control device of the present utility model to control wheelchair, first need wheel-chair control device to carry out school zero processing,, in the time not applying power on handle, signal processing device is set up does not have signal input.Then the power being subject to according to handle is controlled wheelchair, and in the time of handle under tension, wheelchair retreats; In the time that handle is subject to thrust, wheelchair advances; When wheelchair had both been subject to thrust also when under tension, wheelchair braking.
The convenient electric wheelchair structure of controlling of the present utility model is simple, only need control device be set in the handle at wheelchair rear portion 1 position, just can greatly save wheelchair entourage's strength.The benefit of this device is that entourage can be by study, carrying out when wheel chair sport as gone up a slope or when descending, control system is controlled the moment of torsion of driving wheel after treatment according to power suffered on handle 1, thereby reaches the effect of power-assisted.
