[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 which can effectively reduce the noise of automobile tires. The sound-absorbing strip includes a base layer, a top layer, a sound-absorbing layer, a groove, a sound-absorbing hole and a sponge. Noise enters the first cavity. Through the arrangement of the sponge, the first wave layer and the second wave layer, the sponge weakens the noise, and the first The wave layer and the second wave layer can absorb the diffused noise in multi-angle and multi-direction, and weaken the noise. The remaining noise enters the second cavity through the second through hole, and the sound insulation cotton is formed through the cooperation of the convex strips and the sound insulation cotton. The corrugated shape is beneficial to increase the surface area, thereby increasing the absorption of noise. Through the arrangement of the above structure, the friction noise generated between the tire and the ground can be eliminated to the maximum extent, thereby improving the driver or the ride. Acoustic comfort of personnel.
