Problems solved by technology
[0002] Most of the tire noise is a kind of noise formed by the air squeeze inside the tire pattern gap and the outside air during the driving process of the vehicle. The noise brought by the road surface, which is transmitted from the car components to the interior of the car body, thus affecting the acoustic comfort of the driver and passengers. It will cause damage to the bottom of the vehicle body. In addition, if there are metal objects such as iron nails on the ground during driving, it is easy to puncture the tires and increase the danger of driving. Therefore, it is necessary to design a tire cover that can effectively reduce the noise of automobile tires

The invention discloses a tire cover capable of effectively reducing car tire noise. The tire cover comprises a tire cover body, sound absorption strips, a clamping groove, a clamping head, an anti-sliding groove, an adhesive and sound absorption cotton. The sound absorption strips are arranged in the tire cover body, each sound absorption strip comprises a base layer, a top layer, a sound absorption layer, a groove, sound absorption holes and sponge, the noise enters a first cavity, the noise is weakened by the sponge by arranging the sponge, a first wave layer and a second wave layer, multi-angle multidirectional absorption can be carried out on the diffused noise through the first wave layer and the second wave layer, and the noise is weakened, and the remaining noise penetrates throughsecond through holes to enter a second cavity; by means of cooperation of convex strips and sound insulation cotton, the sound insulation cotton is corrugated, the superficial area can be increased,and the absorbed noise can be increased. By means of the structural arrangement, the friction noise generated between a tire and the ground can be eliminated maximumlly, and therefore the acoustic comfort for drives or passengers is improved.
