Detailed description of the invention

Below according to the drawings and specific embodiments, the utility model is described in further detail:

As shown in Figure 1, 2, a kind of electric wheelchair, including vehicle frame 8, backrest and across foot 2,2 trailing wheels 5 of 20,2 front-wheels, driving device, battery 3 and be connected with vehicle frame 8 across foot 20, driving device includes left and right motor 4, the output shaft of this left and right motor 4 is connected with trailing wheel 5, battery 3 is placed in the battery basket on vehicle frame, it is linked with the battery that is fastened with battery, motor 4 is brush motor, it is fixed on the fixing pipe 6 of trailing wheel by screw-nut, the fixing pipe 6 of trailing wheel is connected with vehicle frame 8 by screw and spring, and spring plays cushioning effect；Two front-wheels 2 are fixed on wheel fork 1 by bolt and nut and bearing, and wheel fork 1 is by locking with Anti-slip nut after the bearing in the fixing pipe of vehicle frame front-wheel, and wheel fork 1 can fix the bearing rotary in pipe around front-wheel, thus front-wheel reaches the effect of universal wheel；nullIt is responsible for 20-1 across foot across what foot 20 included being sequentially connected with、Connecting leg 20-2 and across underfooting connecting leg 20-3 on foot，Also include air spring 19、Pedal 20-4，Air spring 19 upper end is fixed on by upper connector (coupling head above air spring) and is responsible for 20-1 across foot，Lower end is fixed on foot on connecting leg 20-2 by lower connector (coupling head below air spring)，One air spring handle with the rotation axle on air spring 19 with threadeding，When the moving axis that rotates pulls air spring handle, air spring 19 will extend automatically，Lift across foot，Press under external force across underfooting connecting leg 20-3 to required angle，External force is removed after unclamping air spring handle，Stagnate in required angle across foot 20，Pedal 20-4 is screwed on the connecting leg 20-3 of underfooting，Can rotate around screw across foot 20.Detachable across foot 20, lift angle across foot 20 and can pass through air spring 19 and regulate and fix, across foot length can by the connecting leg 20-3 of underfooting hole change.Rear wheel vibration damping spring 7 is the fixing pipe 6 of guiding, connecting frame 8 and trailing wheel by bolt, and there is screw hole fixing pipe 6 front end of trailing wheel, is coupled with vehicle frame 8 by bolt, and fixing pipe 6 front aperture of trailing wheel is rotatable, so that it may realizing angle change, compression spring realizes damping.There is screw attachment controller stator bottom controller 13, then have knob to be locked on handrail weld holder 12.Medicated cushion shock-proof spring 21 is guiding, connecting frame 8 and lower vehicle frame by bolt, and the coupling of bolt can realize damping.

Being responsible for 20-1 with connecting leg 20-2 link on foot across foot is arc.

Electric wheelchair of the present utility model also includes left and right handrail 16 and left and right handrail backplate 17, left and right handrail 16 is fixed by screws in the top of handrail weld holder 12 respectively accordingly, left and right handrail backplate 17 is separately fixed at handrail weld holder 12 medial surface, handrail weld holder 12 is fixed on medicated cushion weld holder 10 by knob, handrail weld holder can up-down adjustment, vehicle frame 8 is with medicated cushion weld holder 10 by drawing pin and spring to be connected, and spring plays cushioning effect.

In the present embodiment, trailing wheel 5 is 12 inches of inflated wheel, and wheel hub coordinates with motor 4 output shaft, transmitting moment of torsion by key connecting, trailing wheel 4 is fastened on motor 4 output shaft by screw, and trailing wheel 4 adopts independent cantilever design, damping effect is better so that travelling more steady, power is more sufficient；Backrest stator 9 lower end is locked on medicated cushion weld holder 10 by screw-nut, and backrest stator 9 upper end is connected with backing tube 15, and the hole on backrest stator 9 makes the angle between backrest 14 and medicated cushion 18 to regulate；Thin medicated cushion 11 is by screw lock on medicated cushion weld holder 10, and backrest 14 is by screw lock on backing tube 15, and thick medicated cushion is bonded on thin backrest 15 by adhesive tape；Backrest 14 by draw pin can adjusting angle, user can select oneself comfortable angle.

But, above-mentioned detailed description of the invention is illustrative of, and is to better make to skilled artisans appreciate that this patent, it is impossible to be not understood as this patent is included the restriction of scope；As long as any equivalent change made according to the disclosed spirit of this patent or modification, each fall within the scope that this patent includes.
