Description

一种车辆电动尾门撑杆止转结构
技术领域
本发明涉及属于汽车零部件领域，具体涉及一种车辆电动尾门撑杆止转结构。
背景技术
现有电动尾门撑杆，是利用直流减速电机带动丝杆转动使汽车尾门完成开启与关闭。丝杆的转动需要限位止转结构来限定尾门开启的最大角度，一般丝杆限位结构有两种，一种是轴套侧面铆接，表面植绒，轴套侧面铆接工艺简单，但轴套侧面铆接强度低，存在一些潜在的失效模式，另一种是塑料件和金属平垫轴向铆接，轴向铆接，冲压力大，工艺相对复杂，容易将丝杆损坏。
发明内容
本发明的目的是克服现有技术中存在的不足，提供一种汽车电动尾门撑杆止转结构，可以有效防止丝杆转动和脱落。
为实现上述目的，本发明采用如下技术方案：
一种车辆电动尾门撑杆止转结构，包括导向杆、螺旋丝杆、丝杆螺母，丝杆螺母与导向杆铆接连接，螺旋丝杆通过丝杆螺母在导向杆内转动，其特征在于，所述螺旋丝杆深入导向杆一端设有弹性挡圈卡簧，导向杆远离丝杆螺母一端设置有螺纹槽，螺纹槽的直径大于弹性挡圈卡簧的直径。
作为本发明的进一步改进，所述弹性挡圈卡簧与螺旋丝杆之间依次设置有金属挡圈和POM挡头。
作为本发明的进一步改进，所述POM挡头采用POM材质。
作为本发明的进一步改进，所述弹性挡圈卡簧的结构采用无凸耳设计。
本发明具有以下优点：
1、装配简单，生产效率高；
2、可以有效防止丝杆转动和脱落；
3、噪音小、拆换容易、可反复使用、性能稳定。
附图说明
图1为本发明的结构示意图。
附图标记说明：1-导向杆，2-弹性挡圈卡簧，3-金属挡圈，4-POM挡头，5-螺旋丝杆，6-丝杆螺母,1-1-螺纹槽。
具体实施方式
下面结合具体附图对本发明作进一步说明。
如图1所示，一种车辆电动尾门撑杆丝杆止转结构,它分别由导向杆1、弹性挡圈卡簧2、金属挡圈3、POM挡头4、螺旋丝杆5、丝杆螺母6等零部件构成。丝杆螺母6与导向杆1铆接连接，螺纹槽1-1用于连接外部球头，螺旋丝杆5通过丝杆螺母6在导向杆1内位移转动，直至螺旋丝杆5深入导向杆1一端设有的弹性挡圈卡簧2被导向1杆远离丝杆螺母一端设置的螺纹槽1-1处内的外部球头阻挡而停止移动，螺旋丝杆5向下运动时因POM挡块4受到丝杆螺母6的端面阻挡而停止移动，最终达到了使螺旋丝杆5止转的效果。
所述的弹性挡圈卡簧2压入螺旋丝杆5上的卡簧槽，完全挡住金属挡圈3，使金属挡圈3处于固定状态，所述的POM挡头4，被金属挡圈3挡住。POM挡头4主要用于螺旋丝杆5内部导向，POM挡头4在螺纹导向杆1内壁滑动。
所述的挡头4采用的是POM材质，POM材质有一定耐摩特性。
所述的弹性挡圈卡簧2的结构采用的是挡圈的特殊工艺设计，无凸耳设计，不会干涉其它零配件，安装简单、拆换容易、可反复使用、性能稳定。
具体工作原理：本发明中设计的一种尾门电动撑杆的丝杆止转结构，是利用弹性挡圈卡簧2，挡住丝杆的止转，同时引用POM材质的特性作为内导向的滑动块，减少摩擦系数，降低噪音。有效的保证了撑杆丝杆止转，降低撑杆运行噪音，进一步优化电动尾门撑杆的结构。
