DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0021] Please refer to FIG. 1 FIG. 4, an obstacle-adaptive mechanism of a moving device mainly comprises a driving wheel 100, a driving gear 110, a passive wheel 200, a passive gear 210, an intermediate gear 300, a driving unit 400, a tire 500, and a wheel case unit 600. One side of the driving wheel 100 is connected to a driving gear 110, one side of the passive wheel 200 is connected to the passive gear 210, and the intermediate gear 300 is disposed between the driving gear 110 and the passive gear 210. The driving wheel 100 drives the driving gear 110 to rotate the intermediate gear 300; then the intermediate gear 300 drives the passive gear 210 to let the passive wheel 200 rotate with the driving wheel 100 in the same direction. The driving unit 400 is connected to the driving wheel 100 and provides power to the driving wheel 100 to enable the driving wheel 100, and the driving gear 110 drives the intermediate gear 300 to keep the passive gear 210 and the driving gear 110 rotating in the same direction.

[0022] Besides, the obstacle-adaptive mechanism of the moving device uses a driving wheel 100, a driving gear 110, a passive wheel 200, a passive gear 210 and an intermediate gear 300 as a transmission mechanism, while compared to prior art obstacle-adaptive mechanisms using caterpillar bands, the transmission mechanism comprising the driving wheel 100, the driving gear 110, the passive wheel 200, the passive gear 210 and the intermediate gear 300 is simple in structure, and is light and agile, it can cross various obstacles without the need of expensive high power driving unit and has low manufacturing cost.

[0023] Furthermore, the outer rims of the driving wheel 100 and the passive wheel 200 are disposed with tires 500 to protect the driving wheel and the passive wheel when the driving wheel and the passive wheel are rolling. The tires can protect the driving wheel 100 and the passive wheel 200 by increasing the friction with the ground and reducing the abrasion of the driving wheel 100 and the passive wheel 200. Besides, advantages such as strong grip and large contacting area of the tire 500 can facilitate the rolling speed of the driving wheel 100 and the passive wheel 200 to improve the efficiency of the obstacle-adaptive mechanism of the moving device.

[0024] Besides, the driving wheel 100, the driving gear 110, the passive wheel 200, the passive gear 210, and the intermediate gear 300 are disposed in the wheel case unit 60. The wheel case unit 600 can hold the driving wheel 100 and the passive wheel 200 in position to protect the driving wheel 100 and the passive wheel 200, meanwhile, it can also prevent the driving gear 110, the passive gear 210 and the intermediate gear 300 from damages caused by the driving wheel 100 and the passive wheel 200 hitting any foreign objects.

[0025] Please refer to FIG. 5 and FIG. 6, the obstacle-adaptive mechanism of the moving device further comprises a body 700 and shock absorbing unit 800, the body 700 comprises an upper case body 710 and a lower case body 720, the upper case body 710 and the lower case body 720 cab be assembled to provide a containing space, wherein the driving unit 400 and the wheel case unit 600 is disposed within the containing space. When the driving wheel 100 and the passive wheel 200 rotate to move the body 700, the body 700, the upper case body 710, and the lower case body 720 can protect the driving unit 400 and the wheel case unit 600 from being damaged by external force when the driving wheel 100 and the passive wheel 200 bump into some foreign object, thereby preventing the obstacle-adaptive mechanism of moving device from deviating from the original path.

[0026] Moreover, the shock absorbing unit 800 comprises the retractable body 810 made of spring, the connecting pole 820 and the fixed pole 830, wherein the retractable body 810 is disposed between the connecting pole 820 and the fixed pole 830, the connecting pole 820 and the fixed pole 830 are disposed on top of the driving unit 400 and the lower case body 720 respectively. When the body moves on a bumpy road through the rotation of the driving wheel 100 and the passive wheel 200, the shock absorbing unit 800 can absorb the vibration to hold the driving wheel 100 and the passive wheel 200 steady, thereby allowing the body 700 to continue to move towards the obstacle.

[0027] Please refer to FIG. 7, when the body 700 is crossing the obstacle 900, the driving wheel 100 first crosses over the obstacle 900, then the passive wheel 200 moves towards the obstacle 900 to allow the body 700 to successfully cross the obstacle 900, thereby enhancing the ability of the obstacle-adaptive mechanism of the moving device crossing the obstacle 900.

[0028] Please refer to FIG. 8, when the driving wheel 100 of the obstacle-adaptive mechanism of the moving device is stuck by the barrier 910 and the body 700 cannot cross the barrier 910, the driving wheel 100 is enabled to drive the passive wheel 200 to move towards the barrier 910 to help the body 700 cross the barrier 910 successfully while maintains the balance and stability of the body 700 without slipping from the barrier 910, thereby enabling the obstacle-adaptive mechanism of the moving device to provide the effect of crossing the barrier 910.
