Description

三刮片柔性壁圆孔内支撑线轮驱动雨刮器
所属技术领域
本发明涉及一种雨刮器,属汽车雨刮器领域,尤其是柔性壁支承雨刷线轮驱动的雨刮器。
背景技术
目前,市场上的雨刮器的雨刷驱动机构多数为连杆传动,其工作时的噪声较大,并且,连杆传动机构为敞开式,受外部影响较大,在工作时如遇到障碍物阻挡易导致雨刮电机烧毁;市场上的雨刮胶条的刮片的支承台通常都是刚性的,由于风挡玻璃是曲面形状,加之制造原因以及使用过程磨损等原因造成风挡玻璃表面不规则缺陷,在刚性支承下的刮片很难适应风挡玻璃表面的变化,而且只有一个刮片,在刮除的过程中刮净度低,刮除效率差,不易快速刮净,易造成视线模糊,给行车带来安全隐患。
发明内容
为了克服现有雨刮器驱动机构工作时噪声较大,并且,连杆传动机构为敞开式,受外部影响较大,在工作时如遇到障碍物阻挡易导致雨刮电机烧毁的弊端;雨刮胶条的刮片在刚性支承下的刮片很难适应风挡玻璃表面的变化,在刮除的过程中刮水效率低,不易快速刮净,本发明提供一种三刮片柔性壁圆孔内支撑线轮驱动雨刮器,它是一种完全封闭的结构,噪声低,而且不受外部环境影响;雨刮胶条能更好地与风挡玻璃贴合,并能够迅速刮净。
本发明解决其技术问题所采用的技术方案是:一种三刮片柔性壁圆孔内支撑线轮驱动雨刮器,包括雨刮电机(36)和雨刷驱动机构(70)以及雨刷(31),所述雨刷驱动机构(70),其结构为:雨刷驱动轴(50)分为被动轮雨刷驱动轴(32)和主动轮雨刷驱动轴(49),并分别设于被动轮固定座(34)的被动轮雨刷驱动轴孔(51)和主动轮固定座(47)的主动轮雨刷驱动轴孔(52)内;被动轮雨刷驱动轴(32)和主动轮雨刷驱动轴(49)上分别设有被动绕线轮(33)和主动绕线轮(37),被动绕线轮(33)和主动绕线轮(37)之间通过柔性线绳(35)连接并传递扭矩。
在主动绕线轮(37)上设有一正反转齿轮间歇传动机构(53),其结构为:在主动绕线轮(37)轴向一侧设有与主动绕线轮(37)同轴联动的绕线轮齿轮(38),在主动轮雨刷驱动轴(49)的径向两侧对称设置两个半圆齿轮,即右半圆齿轮(41)和左半圆齿轮(42),分别与绕线轮齿轮(38)交替啮合;在右半圆齿轮(41)和左半圆齿轮(42)的轴向一侧设置两个分别与右半圆齿轮(41)和左半圆齿轮(42)同轴联动的右驱动齿轮(39)和左驱动齿轮(40),在右驱动齿轮(39)和左驱动齿轮(40)之间设有一与右驱动齿轮(39)和左驱动齿轮(40)相啮合的蜗杆(46),蜗杆(46)的一端与雨刮电机轴(45)相接。
所述雨刷(31),在雨刮胶条(1)的上部设有雨刮胶条固定卡槽(2),下部设有刮片(6),其特征是:在所述雨刮胶条固定卡槽(2)的底板(3)内沿雨刮胶条(1)的轴向左右对称平行设置两条管状空腔,左腔体(17)和右腔体(16),形成左柔性壁(4)和右柔性壁(5)以及中隔壁(12),底板(3)和左腔体(17)以及右腔体(16)构成柔性壁支承结构(7);在底板(3)的两侧下端分别设有延柔性壁支承结构(7)轴向平行设置的左刮片(10)和右刮片(11)以及中刮片(14)。刮片在柔性壁支承结构支承下能够更好地适应风挡玻璃的曲面变化,更好地贴合使刮净度增加,两条管状空腔在保证柔性壁柔度的同时,又具备一定的抗过度变形并保持稳定的作用,而三刮片结构是一般的单刮片刮除效率的三倍。
左柔性壁(4)和右柔性壁(5)的壁厚从壁的上下端向中间呈由厚逐渐变薄的渐变状。左柔性壁(4)和右柔性壁(5)的中部向外凸起。这种设计使柔性壁支承结构具有良好的柔度的同时又具有很好的稳定性。
左刮片(10)和右刮片(11)以及中刮片(14)的上端分别设有左刮片倒梯形支承台(9)和右刮片倒梯形支承台(8)以及中刮片倒梯形支承台(15)。倒梯形支承台设计是防止刮片倒伏,起支撑和加强作用,增强刮片的韧度并兼有防止柔性壁支承结构过度变形的作用。
柔性线绳(35)外部设有软轴套(48),起保护作用,柔性线绳(35)为钢索。
本发明的有益效果是雨刮器的雨刷驱动机构用柔性线绳传动,并且是完全的封闭结构,工作时噪声低,尤其适合外部环境结构复杂以及远距离传动,能够适应不同车型,且不受外部影响,避免了因外部障碍物导致雨刮电机烧毁的弊端,有效地降低了车内噪声,提高了车辆运行时内部的舒适性;刮片在柔性支承结构的支承下与雨风挡玻璃的曲面贴合度更好,从而提高雨刮片的刮净度,两条管状空腔在保证柔性壁柔度的同时,又具备一定的抗过度变形并保持稳定的作用,三刮片结构是一般的单刮片刮除效率的三倍,刮除效率提高,能够迅速给驾驶者提供清晰透明的视线区域,给安全行车提供了有力的保障。
