The second resisting portion 12 is extended downward to resist the muddy water thrown at the bottom of the first resisting portion 11, and reduce the muddy water from being thrown from the side of the first resisting portion 11 close to the wheel cover 2 into the wheel cover 2 and reaching the top of the first resisting portion 11. Therefore, the sealing performance of the wheel sealing structure is better, and the possibility of muddy water being thrown into the cargo cavity is reduced.

[0035] In addition, the wheel cover 2 is detachably connected to the vehicle body 102, which is convenient for installation and removal and saves installation time. Specifically, the vehicle body 102 includes a crossbeam 1021 and a vertical beam 1022, and the wheel cover 2 is detachably connected to the vertical beam 1022. The vehicle body 102 also includes a side enclosure 1023, which is arranged above the wheel cover 2. The wheel sealing structure also reduces the possibility of muddy water being thrown into the bottom of the side enclosure 1023.

[0036] Optionally, in the present embodiment, the stopper 1 further includes a third stopper 13, and the first stopper 11 is welded to the vehicle body 102 via the third stopper 13. Specifically, the third stopper 13 is fixed to one end of the first stopper 11 close to the vehicle body 102 and extends downward, and the side wall of the third stopper 13 is welded to the vehicle body 102. The third stopper 13 extends downward, which further blocks the muddy water entering the stopper 1. In addition, welding the side wall of the third stopper 13 to the vehicle body 102 increases the welding area and improves the connection reliability between the stopper 1 and the vehicle body 102.

[0037] Optionally, the second blocking portion 12 fits and presses against the inner wall surface of the wheel housing 2, which can better prevent muddy water from being thrown into the cargo chamber from the side of the blocking member 1 away from the vehicle body 102, improving the sealing performance of the wheel sealing structure. For the convenience of processing, optionally, in this embodiment, the second blocking portion 12 extends downward in the vertical direction. In other embodiments, the second blocking portion 12 may extend downward in an inclined direction, with the end of the second blocking portion 12 facing the vehicle body 102 or away from the vehicle body 102.

[0038] Optionally, in this embodiment, as Figure 2 and Figure 3 shown, the top wall of the wheel housing 2 is provided with an opening 21, and the width of the opening 21 is smaller than the width of the first blocking portion 11. With such a setting, while blocking muddy water, materials can be saved. In other embodiments, the end faces of the wheel housing 2 close to the vehicle body 102 are all in contact with the vehicle body 102, and the effect of blocking muddy water is better.
