Description
本發明涉及汽車配件領域，尤其涉及一種具有降低噪音之雨刷膠條及具有所述雨刷膠條的雨刷。The invention relates to the field of auto parts, in particular to a windshield rubber strip with noise reduction and a windshield wiper with the windshield rubber strip.
汽車快速發展的今天，車廠和車主都對雨刷的靜音效果越來越重視，然而現有的雨刷膠條通常為通體結構，在雨刷工作時，來回刮拭的雨刷快速運行至行程盡頭換方向的一瞬間，由於膠條的傾斜方向（又稱攻擊角）在瞬間改變，雨刷膠條的刮刃上端部位在換向瞬間會撞擊膠條的緩衝部底端，現有產品總能聽到類似敲擊玻璃的噪音，雨刷膠條的緩衝部位減振效果差，不能很好的吸收雨刷膠條換向產生的瞬間撞擊力。Today, with the rapid development of automobiles, car manufacturers and car owners are paying more and more attention to the quiet effect of wipers. However, the existing wiper strips are usually of a whole-body structure. In an instant, because the inclination direction (also known as the angle of attack) of the rubber strip changes instantly, the upper part of the scraping blade of the wiper rubber strip will hit the bottom of the buffer part of the rubber strip at the moment of changing direction, and the existing products can always hear a sound similar to knocking on the glass. Noise, the damping effect of the buffer part of the wiper rubber strip is poor, and it cannot well absorb the instantaneous impact force generated by the wiper rubber strip changing direction.
因此，如何提供一種在雨刷換向時噪音小的緩衝降噪雨刷膠條及具有所述雨刷膠條的雨刷是本領域技術人員亟需解決的問題。Therefore, how to provide a cushioning and noise-reducing wiper strip with low noise when the wiper changes direction and a wiper with the wiper strip is an urgent problem to be solved by those skilled in the art.
有鑑於此，本發明提供了一種具緩衝及降低噪音的雨刷膠條及具有所述雨刷膠條的雨刷，其具有刮拭效果好、使用雜音小的優點。In view of this, the present invention provides a wiper rubber strip with cushioning and noise reduction and a wiper with the wiper rubber strip, which has the advantages of good wiping effect and low noise in use.
