The longitudinal cross-sections of the front mud tile 1 and the rear mud tile 2 are both V-shaped structures, so that the front mud tile 1 and the rear mud tile 2 are used to shield the top of the wheel.

[0020] A gas spring 5 and a guide rod 6 are provided at the bottom of the folding mud tile, and the opening and closing angles of the front mud tile 1 and the rear mud tile 2 can be adjusted by the gas spring 5 and the guide rod 6, so as to avoid the folding mud tile interfering with the normal opening of the hood inspection door 7 after being folded.

[0021] Specifically, Figure 3 As shown, two gas springs 5 ​​are provided, and the two gas springs 5 ​​are respectively arranged on both sides of the bottom of the front mud tile 1, a first gas spring bracket 8 is fixed to the side of the walkway 3 close to the front mud tile 1, and a second gas spring bracket 9 is provided at one end of the bottom surface of the front mud tile 1 close to the rear mud tile 2, and the two ends of the gas spring 5 are respectively hinged to the first gas spring bracket 8 and the second gas spring bracket 9, and the gas spring 5 can provide assistance for the opening and closing of the front mud tile 1.

[0022] The first gas spring bracket 8 is fixed on the walkway 3 by bolts, and different gas spring brackets can be replaced according to different types of gas springs 5, which improves its applicability.

[0023] A plurality of gas spring mounting holes 10 are provided at one end of the first gas spring bracket 8 away from the walkway 3. The plurality of gas spring mounting holes 10 are arranged side by side. One end of the gas spring 5 is detachably connected to the gas spring mounting hole 10, so that the end of the gas spring 5 can be rotatably connected to different gas spring mounting holes 10, thereby adjusting the telescopic length of the gas spring 5 and further adjusting the opening and closing angle of the front mud shoe 1.

[0024] Furthermore, the gas springs 5 ​​of different lengths can be replaced, and the opening and closing angles of the front mud shoe 1 can also be adjusted.

[0025] Adjusting the opening angle of the front mud tile 1 can limit the initial position of the front mud tile 1 and the final opening position of the front mud tile 1. Limiting the initial position of the front mud tile 1 keeps the upper surface of the front mud tile 1 in a horizontal position. In this position, the front mud tile 1, the rear mud tile 2 and the lock can cooperate with each other to keep the folding mud tile in a rigid state. Limiting the final opening position of the front mud tile 1 prevents the front mud tile 1 from colliding with components such as the power battery arranged in front, while ensuring that the hood inspection door 7 can be opened normally.
