It can be understood that the first rotation pivot 113 can also be disposed on the side of the open end 112 away from the ground.

Similarly, when the first rotation pivot 113 is arranged on the side of the open end 112 away from the ground, when the vehicle needs to be supported, the piston 132 of the oil cylinder shrinks, so that the support member 120 quickly rotates and stretches, and when the piston When the 132 is fully stretched out, the support member 120 is in contact with the ground, the hydraulic pump stops working, and the oil cylinder is self-locked, so that the above-mentioned vehicle outrigger structure 100 supports the vehicle. When the outrigger structure 100 of the vehicle needs to be stowed, the piston 132 is extended to drive the supporting member 120 to reversely rotate and stow away. When the stroke of the piston 132 ends, the hydraulic pump stops working, and the oil cylinder self-locks to complete the packing process. During the above-mentioned support or retraction process, the piston 132 can complete the support or retraction of the support member 120 within a short stroke, which improves the use efficiency.

Compared with the traditional vehicle outrigger structure, the vehicle outrigger structure 100 has at least the following advantages:

And because there is a certain distance between the first pivot 113 and the second pivot 115 , the connecting part 110 , the telescoping part 130 and the supporting part 120 form a triangle. When the telescopic member 130 is stretched or contracted, according to the nature of the triangle, if one side of the triangle changes, the shape of the other triangle will change accordingly. Therefore, the telescopic member 130 rotates around the second pivot 115 to drive the support The member 120 rotates about the first rotation pivot 113 . When it is necessary to use the vehicle outrigger structure 100 to support the vehicle body, the support member 120 is rotated toward the ground so that the support member 120 abuts against the ground and the vehicle body to achieve the effect of supporting the vehicle body. When it is not necessary to use the vehicle outrigger structure 100 to support the vehicle body, the support member 120 is turned away from the ground, and then the support member 120 is retracted. Since the supporting member 120 supports the vehicle from one side of the vehicle body, an included angle is formed between the supporting member 120 and the ground. Due to the stability of the triangle, the stability of the supporting member 120 supporting the vehicle can be improved.

Again, one end of the support member 120 is provided with a leg 140, which is in contact with the ground, and the force bearing area of the leg 140 is larger than that of the support member 120, which can prevent the support member 120 from being deformed due to excessive pressure. Moreover, the larger side of the support leg 140 is in contact with the ground, so that the pressure can be evenly distributed, preventing the support leg 140 from sliding and affecting the supporting effect of the vehicle support leg structure 100 on the vehicle. Moreover, the above-mentioned vehicle outrigger structure 100 has a simple structure and saves cost.
