Abstract

A moving mechanism includes a support; a driving device mounted on the support; a controller arranged on the support; two sets of moving assemblies respectively mounted at two ends of the support; wherein each of the moving assemblies includes a track and two synchronous wheels of different diameters arranged inside the track, such that the moving mechanism is functioned and run freely over stairs, rugged road surfaces and all-terrain ground under the action of the driving device and the controller. Besides, the moving mechanism is equipped on electric vehicles and toys. The moving mechanism applies a breakthrough composite structure of a half-wheel-half-track configuration in combination with an additional omni-directional wheel, whereby the moving mechanism and the electric vehicles and toys equipping the same are adaptable to different road surfaces and stairs of various angles, and also convenient and reliable to use.

Claims

1. A moving mechanism, comprising:

a support;

a driving device mounted on the support;

a controller arranged on the support;

two sets of moving assemblies respectively mounted at two ends of the support;

wherein each of the moving assemblies includes a track and two synchronous wheels of different diameters arranged inside the track;

a forearm drive axle mounted on the support and arranged between the two synchronous wheels of different diameters; and

an omni-directional wheel connected with the forearm drive axle via a connecting member, so as to swing;

whereby the moving mechanism moves freely over stairs, rugged road surfaces and all-terrain ground under action of the driving device and the controller.

2. The moving mechanism of claim 1, wherein one of the two synchronous wheels of different diameters and an auxiliary synchronous wheel are both mounted on an axle, such that the one of the two synchronous wheels of different diameters and the auxiliary synchronous wheel are rotated concurrently.

3. The moving mechanism of claim 2, wherein the two synchronous wheels of different diameters are respectively provided with a fixing plate, which allows the axle to rotate with respect to the fixing plate via a bearing.

4. The moving mechanism of claim 3, wherein the forearm drive axle is connected with the fixing plate at both ends, so as to make the fixing plate swing when the forearm drive axle rotates.

5. The moving mechanism of claim 4, wherein the forearm drive axle is driven by a forearm motion mechanism, the forearm motion mechanism comprises a first forearm driving electric push rod and a second forearm driving electric push rod connected with the forearm drive axle, so as to drive the forearm drive axle to rotate or swing.

6. The moving mechanism of claim 1, wherein a synchronous track is arranged between the moving assemblies, so as to implement synchronous transmission of power between the synchronous wheels.

7. The moving mechanism of claim 1, wherein a synchronous wheel connector is arranged between the two synchronous wheels of different diameters, so as to transfer power between the two synchronous wheels of different diameters.

8. The moving mechanism of claim 1, wherein a plurality of teeth are arranged on the track.

9. An electric vehicle comprising a body part and a seat, further comprising a moving mechanism of claim 1, such that the electric vehicle moves freely over stairs, rugged road surfaces and all-terrain ground surfaces by making use of the moving mechanism.

10. The electric vehicle of claim 9, wherein the electric vehicle further comprises a seat adjustment mechanism connected with the seat and configured to effect an up and down adjustment of the seat in a direction perpendicular to the body part, or a horizontal adjustment of the seat in a direction parallel to the body part, or an adjustment of the seat in a rotary manner, so that the seat is moved up and down and left and right, or rotatably adjusted in directions from 0°

to 360°

.

11. The electric vehicle of claim 10, wherein the seat adjustment mechanism comprises a seat balance mechanism comprising:

a seat balance push rod arranged under the seat to drive the seat to move in one direction or two directions;

a balance sensing element for sensing an information on whether the seat is deviated, and transmitting the information to a control unit; and

;

the control unit is electrically connected with the seat balance push rod and the balance sensing element to receive the information transmitted by the balance sensing element, and control the seat balance push rod according to the information, so as to maintain balance of the seat.

12. The electric vehicle of claim 11, wherein the balance sensing element is a gyroscope.

13. The electric vehicle of claim 11, wherein the seat adjustment mechanism comprises a seat rotation mechanism comprising:

a connecting bracket fixedly connected with one end of the seat of the seat balance push rod;

a driving device mounted on the connecting bracket;

a swivel bracket connected with the connecting bracket at a joint, at which a ball bearing is arranged; and

a screw rod arranged at one end of the driving device and driven by the driving device to rotate, and drive the swivel bracket to rotate.

14. An electric vehicle of claim 13, wherein the seat adjustment mechanism further comprises a gear arranged at one end of the swivel bracket, and rotated collaboratively with the screw rod.

15. The electric vehicle of claim 13, wherein the driving device is a deceleration motor.

16. The electric vehicle of claim 9, wherein the electric vehicle further comprises an armrest arranged at the support, and positioned in front of the seat for easy grip and allowing the electric vehicle to be controlled via a button arranged on the armrest.

17. A toy, comprising a moving mechanism of claim 1, such that the toy moves freely over stairs, rugged road surfaces and all-terrain ground surfaces by making use of the moving mechanism.
