When the vehicle body 200 collides with an obstacle such as the obstacle 300, the vehicle body stepped-up device 100 rotates along a collision point by the stepped mechanism 10 and lifts the vehicle body 200 until the first link 20 is separated from the stepped mechanism 10, and at this time, the stepped mechanism 10 forms a slope between the obstacle 300 and the vehicle body 200 for the vehicle body 200 to pass over the obstacle 300.

The upper-step mechanism 10 comprises a rotating part 11, an expansion part 12 and a weight part 13, wherein the expansion part 12 is telescopically arranged at the lower end of the rotating part 11, the weight part 13 is rotatably connected to the upper end of the rotating part 11, so that when the weight part 13 rotates, the rotating part 11 is driven to incline, the rotating part 11 and the expansion part 12 are abutted against the obstacle 300 to form a slope, and the vehicle body 200 is supplied to pass through. In a specific embodiment, the rotating member 11 and the telescopic member 12 are both long straight plates, and the weight member 13 is an iron block. It is understood that the shape and number of the rotating member 11, the telescopic members 12 and the kinds of the weight members 13 are not limited thereto, and as in other embodiments, the rotating member 11 and the telescopic members 12 are long straight rods and the weight members 13 are sandbags. The upper mechanism 10 includes two rotating members 11 and two telescopic members 12, two telescopic members 12 are respectively telescopically arranged at the lower ends of the rotating members 11, and two rotating members 11 are arranged side by side at the front end of the vehicle body 200 to allow the wheels of the vehicle body 200 to pass through.

The upper mechanism 10 further includes a driving member (not shown) disposed at a lower end of the rotating member 11, when the vehicle body 200 collides with the obstacle 300, the vehicle body 200 presses the driving member, and the driving member drives the extensible member 12 to extend and retract. It will be appreciated that the drive member may be a drive motor or other drive device that can drive the telescoping member 12 to telescope.

The upper mechanism 10 further includes a fixing member (not shown) disposed on the extensible member 12, and when the driving member drives the extensible member 12 to a predetermined length, the fixing member fixes the rotating member 11 and the extensible member 12, so as to improve stability of the upper mechanism 10 and facilitate passage of the vehicle body 200.

The upper step mechanism 10 further comprises a rotator 14, the rotator 14 is fixed at the upper end of the rotating member 11, and the weight member 13 is rotatably connected at the upper end of the rotator 14. In one embodiment, the rotator 14 is a hinge, and the weight 13 is hinged to the rotator 14. When the vehicle body 200 collides with the obstacle 300, the weight 13 is rotated from the side close to the vehicle body 200 to the side away from the vehicle body 200 by inertia. It is understood that the type of the rotator 14 is not limited thereto, and as in other embodiments, the rotator 14 is a combination of a driving device and a sensor, and when the sensor senses that the vehicle body 200 collides with the obstacle 300, the driving device is controlled to drive the counterweight 13 to rotate from a side close to the vehicle body 200 to a side away from the vehicle body 200.

The upper step mechanism 10 further comprises a second connecting member 15, the second connecting member 15 is fixed on the rotating member 11, and the second connecting member 15 is movably connected with the first connecting member 20.

Referring to fig. 2, in one embodiment, when the vehicle body 200 collides with the obstacle 300, the vehicle body 200 presses the driving member, and the driving member drives the telescopic member 12 to extend.
