Abstract

一种汽车用双刃雨刮胶条。其主要特点是刮削 部呈人形,有两个刮削刃以铲刮为主代替单刃拖刮, 刮削效果好。有助于提高行车安全性,并减小雨刮器 的功率。

Description

本发明涉及雨刮胶条,特别是一种用于汽车雨刮器上的雨刮胶条。
现有的雨刮胶条都是单刮削刃的。工作时刮削刃后倾拖刮挡风玻璃上的雨水及灰尘但拖刮的刮削效果不理想,且刮削刃的刚性难控制易失稳扭曲。如果胶条的硬度与雨刮器对胶条的压力选择不当,不是刮不干净就是摩擦耗功太大。当反向工作时刮削刃要向另一侧后倾,因此在交替时必然有一个将雨刮器抬起的过程,这会消耗驱动装置的功率。
本发明的目的是为了提供一种双刃雨刮胶条,以双刃刮削,铲刮为主的形式代替单刃拖刮提高刮削效果与效率,减少驱动装置功耗。
为实现上述目的,本发明双刃雨刮胶条的结构如下:双刃雨刮胶条对雨刮器的夹持部份与现有的雨刮胶条相同以便同一型号雨刮胶条互换。双刃雨刮胶条的刮削部呈人形,有二个刮削刃,当雨刮器工作时在运动方向前侧的刮削刃以铲刮形式工作有较好的刮削效果与效率,而另一个刮削刃则以拖刮形式工作,双刃刮削不仅效果好,且支承受力稳定不会扭曲,对挡风玻璃贴合好。对胶条的材质硬度与雨刮器对胶条的压力有可能在较大范围内选择匹配。当雨刮器反向工作时不存在将雨刮器抬起的过程,这就降低了驱动装置功耗。
由上可见本发明双刃雨刮胶条与现有雨刮胶条相比其优点是:以双刃刮削,铲刮为主的形式代替单刃拖刮提高了刮削效果与效率。双刃支撑稳定不会扭曲对挡风玻璃贴合好。高的刮削效率,可合理选择胶条材质、硬度与雨刮器对胶条的压力,以及雨刮器来回工作时不存在抬起过程等均导致驱动装置功耗减小。故本发明是一种高效、节能的雨刮器元件。能提高行车的安全性,并减小雨刮器驱动装置的功率、重量、尺寸。
下面结合附图所示实施例对本发明作进一步说明:
图1为本发明双刃雨刮胶条的横断面图。
由于本发明仅涉及雨刮器胶条的横断面故仅就本发明胶条的横断面作分析。由图见本发明双刃雨刮胶条有与现有雨刮胶条相同的夹持部1以便同一型号雨刮器新、老胶条的互换替代。但二者的刮削部2不同,双刃雨刮胶条的刮削部2呈人形,有两个刮削刃工作时前方工作刃有小于90°的前铲角,刮削效果好。在横断面上两个刮削刃与玻璃3均呈点接触状态,中间部份与玻璃3不接触,从而减少了摩擦力。
