[0012] A preferred scheme is that the four sets of wheel hubs of the automobile are respectively provided with corresponding wheel arches, and the air outlet holes of the four sets of wheel arches are connected to the dust suction equipment

[0013] A preferred scheme is that the wheel arches are attached to the positions of the four wheel arches of the automobile and are located above the wheel hubs of the automobile.

[0014] A preferred scheme is that the air outlet holes are connected to the dust suction equipment through the connecting pipes.

[0015] The above scheme has the beneficial effects that:

[0016] The automobile is running on the road, and dust is raised around the tires in the rotating state to form dust raising. The dust suction equipment of the prior art starts to work, the air outlet hole is communicated with the dust suction equipment, the two first air inlet holes and the second air inlet hole suck the dust raising into the wheel arch, and further into the dust suction equipment to complete the dust suction collection and treatment.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Example:

[0030] like Figures 1-4 As shown, this embodiment provides a vehicle dust suppression device, including a vehicle body 5, wheel arches 2, and a dust collection device 1. The wheel arches 2 are fixed to the vehicle body 5 and are located above the wheel hub 4. The wheel arches 2 are arc-shaped shells, as shown... Figure 4 As shown, the arc-shaped shell consists of an inner arc-shaped wall 220, two side end walls 210, and an outer arc-shaped wall 230. The two side end walls 210 have first air inlets 21, and the inner arc-shaped wall 220 has second air inlets 22. The two side end walls 210 are horizontally oriented. Multiple sets of second air inlets 22 are evenly distributed along the extension direction of the inner arc-shaped wall 220. This helps the structure better absorb dust. The outer arc-shaped wall 230 has air outlets 23, preferably in a single set. Furthermore, the dust collection device 1 communicates with the air outlets 23.

[0031] When a car is driving on the road, dust is stirred up around the tires as the car rotates. The existing dust collection device 1 starts working. The air outlet 23 is connected to the dust collection device 1. The two first air inlets 21 and the second air inlet 22 suck the dust into the wheel arch 2, and then into the dust collection device 1 to complete the dust collection and processing. This structure can capture the desorption and suspension of ground particles caused by the airflow disturbance generated by the rotation of the wheels in real time, effectively reducing the dust generated during the car's operation, thereby improving air quality and reducing air pollution.

[0032] like Figure 1 As shown, the dust collection device 1 includes a negative pressure fan 11 and an adsorption container 12. The negative pressure fan 11, the adsorption container 12, and the air outlet 23 are connected in sequence, and dust is adsorbed in the adsorption container 12. The adsorption container 12 is a filter screen adsorption, filter cartridge adsorption, or electrostatic precipitator. Filter screen adsorption, filter cartridge adsorption, or electrostatic precipitator are all existing technologies and will not be described in detail here.

[0033] Preferably, when it is an electrostatic precipitator, the outlet at the bottom of the adsorption container 12 has an ash discharge valve 13 and an ash collection box 14. The ash collection box 14 is used to collect the dust inside the adsorption container 12.

[0034] The four sets of wheel arches 2 are arranged on the four sets of wheel hubs 4 of the automobile, and the air outlet holes 23 of the four sets of wheel arches 2 are connected to the dust suction equipment 1. The wheel arches 2 are arranged at the positions of the four wheel arches 3 of the automobile and above the wheel hubs 4 of the automobile. The air outlet holes 23 are connected to the dust suction equipment 1 through the connecting pipes.

[0035] Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
