Description

Splash water mist eliminating and guiding device for wheel of automobile in running

Technical Field

The invention belongs to the technical field of automobile tire arch bars, and particularly relates to a device for eliminating and guiding water mist splashed by wheels of an automobile in running.

Background

When the automobile runs in rainy days, because the road surface has water, the tire rotates and throws away the adsorbed flying speed, and the splashed water is blocked by the tire arch after leaving the tire, collides with the arch, becomes fine water drops and fog for some, and collides with the rotating tire after being reflected by the arch for some. The water is repeatedly collided between the arch bar and the tyre to be changed into fine particles, and the fine particles are finally changed into water mist under the combined action of the automobile driving side wind and the tyre rotating wind. Therefore, when the automobile runs at high speed in rainy days, the water mist cage covers are always arranged on the peripheries of the tires on the two sides of the automobile. The water mist not only influences the sight of the driver of the vehicle, but also can shield the sight of the drivers of the two vehicles by the water mist splashed by the vehicles when the vehicles overtake or meet in parallel, and the front part of the vehicle comprising the front windshield can be attached by the water mist, thereby influencing the light and the induction device and being not beneficial to the driving safety. In addition, water adsorbed by the tires is thrown out of the arch, and part of the water flows back to the road surface along the arch again, so that the water on the road surface is repeatedly crushed and thrown by front and rear vehicles. According to statistics, the incidence rate of car accidents in rainy days is 5 times that in sunny days, and the main factors are two hidden dangers of visibility and road surface conditions. The existing automobile is only provided with an arch bar with protection and blocking effects, and the automobile is not provided with a guide eliminating device for splashing water mist, so that the water brought by the automobile and the generated water mist can not be shunted and guided when the automobile runs in rainy days, the sight of drivers and passengers is influenced, the information induction and identification of vehicles and a road network are also influenced, and the road network operation safety and the information-based traffic construction are not facilitated.
