Abstract

PURPOSE: A wheel cover of a vehicle is provided to reduce noise from a tire efficiently by absorbing noise from friction between the tire and the road surface, and to prevent mud from being stuck to the wheel cover by manufacturing nonwoven fabric with needle punching. CONSTITUTION: Nonwoven fabric(20) is manufactured with felt or flock, and impregnated with polypropylene. The nonwoven fabric is impregnated with polyethylene, and back-coated with latex for shutting off noise and waterproofing. A polypropylene substrate(30) is mounted in the upper part of the nonwoven fabric made of flock with laminating to prevent noise and keep the shape. The upper part of the nonwoven fabric is laminated with the polypropylene substrate, and the nonwoven fabric is mounted in the upper part of the substrate. The nonwoven fabric is manufactured with needle punching, and a wheel cover is made of nonwoven fabric. Noise from the tire is absorbed with the wheel cover, and driving experience is improved with reducing noise.

자동차용 휠커버{WHEEL COVER FOR CAR}Wheel Cover for Automobile {WHEEL COVER FOR CAR}

본 발명은 자동차용 휠커버에 관한 것으로, 자동차의 타이어에서 발생하는 소음을 효과적으로 감쇄시키며 진흙이 잘 묻지 않는 자동차용 휠커버에 관한 것이다.The present invention relates to a wheel cover for an automobile, and more particularly, to attenuates noise generated from a tire of an automobile and to a wheel cover for an automobile that is hard to get mud.

도 1에 자동차용 휠커버의 사시도를 도시한다.1 is a perspective view of a wheel cover for an automobile.

일반적으로 자동차용 휠커버는 금속으로 된 제품을 사용한다. 이러한 휠커버는 자동차의 타이어로부터 튀어 오르는 진흙을 차단하여 차량의 바디나 내부에 탑승한 승객에게 튀는 것을 방지하며, 타이어에서 발생하는 소음을 반사시킴으로써 차량에 탑승한 승객에게 타이어의 소음에 의한 불쾌감을 줄이는 작용을 한다.Generally, wheel covers for automobiles are made of metal. The wheel cover prevents splashing from the tires of the car to prevent it from splashing on the body of the vehicle or passengers inside the vehicle, and reduces the discomfort caused by the tire noise to the passengers in the vehicle by reflecting the noise generated from the tires. It works.

그런데 종래의 금속으로 된 휠커버는 단순히 타이어의 소음을 반사시키는 작용을 할뿐이므로, 차량의 주위에 있는 사람은 더욱 강한 타이어의 소음을 듣게 되는 문제점이 있다. 또한 금속으로 된 휠커버에 바닥으로부터 튀는 진흙이 묻어 지저분하게 되는 문제점이 있다.However, since the conventional metal wheel cover merely serves to reflect the noise of the tire, there is a problem that a person around the vehicle hears the noise of a stronger tire. In addition, there is a problem that the mud splashing from the bottom of the metal wheel cover is dirty.

본 발명은 종래의 문제점을 개선하기 위하여 안출한 것으로, 본 발명의 목적은 자동차의 타이어에서 발생하는 소음을 효과적으로 감쇄시키며, 진흙이 잘 묻지 않는 자동차용 휠커버를 제공하는 것이다.The present invention has been made in order to improve the conventional problems, an object of the present invention is to effectively reduce the noise generated from the tire of the vehicle, and to provide a wheel cover for a vehicle that does not mud well.
