Abstract
The utility model relates to the field of electric bicycles, in particular to an electric wheelchair for the disabled. The electric wheelchair of the utility model comprises two foldable wheels, a chair and a steering wheel, wherein the two wheels are installed on the low-speed outer rotor of the respective drive electric motor. An electromagnetic brake with a big moment is connected with a outer rotor wheel hub motor, and is installed on the same axis with the motor shaft, a splinter on a armature board on the electromagnetic brake is combined into one with the rotor end cover of the outer rotor wheel hub motor, a magnetic yoke plate with a coil and an abrasion plate is fixedly connected with the framework of the wheelchair. Compared to the prior art, the utility model has the advantages in that the wheelchair is convenient to be folded, transported and stored, with the adoption of the electromagnetic brake with a big moment, the control is eased, the operation is more convenient and comfortable, and the conversion between the manual mode and the electric mode is simple and convenient.
Description
Technical field
This utility model relates to a kind of electricity and drives the bicycle field, is particularly useful for the used electric wheel-chair vehicle of people with disability.
Background technology
Existing electric wheel-chair vehicle adopts mostly the brush high-speed electric expreess locomotive, moves by reduction gearing deceleration rear drive wheelchair.This type of drive complex structure, noise is bigger, and the carbon brush of brush motor is easy to wear, makes troubles to maintenance.More unacceptablely be,, must stir mechanical clutch, make the disengagement of reducing gear and wheelchair driving shaft in electronic and trouble when manually changing.In order to change this situation, Chinese patent (application number is 01229510) discloses a kind of novel wheelchair, and what this wheelchair adopted is the mechanical type brake, and it is all inconvenient to handle control, causes driving comfort not good enough; Inconvenient maintenance is adjusted in the mechanical type brake in addition; The battery of the electric wheelchair of prior art is installed under back afterbody or the seat cushion basically in addition, when wheelchair collection or transportation need to fold, must battery be taken off or relevant parts are pulled down earlier, and is very inconvenient.
Summary of the invention
The purpose of this utility model will provide a kind of exactly can overcome above-mentioned defective, need not dismantle any parts for vast disabled friend provides a kind of, just can fold easily, adopt electromagnetic brake, safe and reliable, not only can electronic but also manual electric wheelchair.
The purpose of this utility model is achieved by the following scheme:
Electric wheelchair of the present utility model includes folding two wheels, seat and deflecting rollers etc., two wheels are installed in respectively on the low speed outer rotor of drive motors separately, the electromagnetic brake device of big moment links to each other with the outer rotor wheel hub motor, and with the coaxial installation of motor shaft, the rotor endcap of shell fragment on its armature plate and outer rotor wheel hub motor links into an integrated entity; The yoke plate that coil and wearing piece are housed is fixedlyed connected with the vehicle frame of wheel Wheel-chair.
Maintain appropriate gap between armature plate of the present utility model and yoke plate.
The battery of electric wheelchair of the present utility model is installed on the sheer pole and middle cross bar of vehicle frame by can.
This utility model compared with prior art has following advantage:
1, need not dismantle any parts, just can fold easily, convenient transportation and storage.
2, adopt the electromagnetic brake device of big moment, make control easier, more convenient to operate and comfortable.
3, adopt the electromagnetic brake device of big moment, make the conversion between manual and electronic simple and convenient.

Fig. 2 a is the side view of wheelchair frame.
The part of Fig. 2 b Fig. 2 a is to view.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
As depicted in figs. 1 and 2, electric wheelchair of the present utility model includes folding two wheels, seat and deflecting rollers etc., two wheels are installed in respectively on the low speed outer rotor of drive motors separately, the electromagnetic brake device of big moment links to each other with the outer rotor wheel hub motor, and with motor shaft 6 coaxial installations, the shell fragment 3 on its armature plate 4 links into an integrated entity with the rotor endcap 2 of outer rotor wheel hub motor 1; The yoke plate 5 that coil and wearing piece are housed is fixedlyed connected with the vehicle frame 7 of wheel Wheel-chair, and 5 of armature plate 4 and yoke plates maintain appropriate gap; The battery 22 of electric wheelchair is installed on the sheer pole 23 and middle cross bar 21 of vehicle frame by can.
Shell fragment 3 on the armature plate 4 of electromagnetic brake device of the present utility model adopts rivet or screw to link into an integrated entity with the rotor endcap of outer rotor wheel hub motor 12; The yoke 5 that coil and wearing piece are housed is connected with the vehicle frame 7 of taking turns Wheel-chair.Above-mentioned armature plate 4 and yoke plate 5 and external rotor electric machine 1 coaxial installation, and armature plate 4 and 5 suitable gap such as 0.3-0.6mm of maintenance of yoke plate.During brake,, armature plate is pressed on the wearing piece on the yoke plate 5 that connects firmly with vehicle frame, make the external rotor electric machine brake, thereby make the deceleration of wheel Wheel-chair or stop convenient control by friction because the electromagnetic force effect impels shell fragment 3, distortion on the armature plate 4.In order to reach this purpose, be milled with flat side on the axle 6 of motor 1, it is corresponding with square hole on the vehicle frame that motor shaft is installed, motor shaft rotation when preventing to brake.In order to prevent the dust foreign material, in the outside of electromagnetic brake device dust cover 8 is housed in addition, its available plastics or metal are made.
Fig. 2 a is the side view of wheelchair frame, and battery 22 is installed between the sheer pole 23 and middle cross bar 21 of wheelchair frame, and fixed form can adopt metal structure or cloth bag mode.The former is the can of an opening, and it adopts screw or welding manner to be connected with wheelchair frame, and battery is put in people's box and got final product; The latter adopts nylon tower button or snap close mode that battery is fixed on sheer pole 23 and the middle cross bar 21.
This utility model adopts two brushless, permanently outer rotor wheel hub motors, directly drives two trailing wheels respectively.Be convenient control and brake, the electromagnetic brake device of employing high pulling torque and wheel hub motor and frame link.During the energising of electromagnetic brake device, motor is stopped extremely; Under the no power state, brake separates with motor, and drivewheel is in free state.This conversion between manual and electronic quite easily and convenient.Need not to dismantle the purpose that any parts just can fold in order reaching, to be placed on controller in the control crank box or to be placed on the protection side plate of handrail; Battery is placed on respectively on the wheel carrier of front-wheel back upper place, adopts flexible circuit conductor to connect between the battery.
