[0001]技术领域

[0002]本发明涉及一种汽车门锁电开机构，具体的说是带自动回位功能的汽车门锁电开机构，属于汽车门锁技术领域。

[0003]背景技术

[0004]汽车门锁是车身重要组成部件之一。随着汽车工业的日渐发展，汽车门锁需要的功能越来越多，功能之一是能够实现汽车门锁的电动/手动解锁；功能之二是能够实现汽车门锁的全锁与半锁，并提供状态信号；功能之三是防止车辆在行驶过程中车门自动打开，保障车内乘客安全。

[0005]目前，市场上现有的执行器的回位功能主要通过弹簧或者电机反转实现的，弹簧回位具有不可靠性，在回位过程中可能出现卡死。电机回位则需BCM程序匹配。

[0006]发明内容

[0007]本发明的目的在于克服上述不足之处，从而提供一种带自动回位功能的汽车门锁电开机构，能够准确高效实现汽车门锁电开和回位功能。

[0008]按照本发明提供的技术方案，带自动回位功能的汽车门锁电开机构包括电机、蜗杆、蜗轮、蜗轮拨杆、限位顶杆、棘爪、限位板和棘爪拨杆，其特征是：电机驱动端连接蜗杆，蜗杆与蜗轮啮合连接，蜗轮侧面沿圆周方向设有至少一个联动块，蜗轮拨杆前端位于联动块的转动路径上，蜗轮拨杆后端固接拨杆转轴，拨杆转轴上固接棘爪拨杆后端，棘爪拨杆前端接触棘爪并位于棘爪转动路径上；限位顶杆前端接触棘爪并位于棘爪转动路径上，限位顶杆中部通过销轴铰接在壳体上，限位顶杆后端延伸到蜗轮处，并使得蜗轮位于限位顶杆转动路径上；蜗轮背面共轴连接限位板，限位板上沿圆周方向设有至少一个限位卡槽，限位顶杆能够卡入限位卡槽中实现开锁状态的锁定。

[0009]进一步的，棘爪上设有推杆，推杆与棘爪拨杆前端接触。

[0010]进一步的，棘爪上设有推块，推块与限位顶杆前端接触。

[0011]进一步的，限位顶杆中部连接的销轴上连接扭簧，扭簧能够让限位顶杆压紧接触棘爪。

[0012]进一步的，限位卡槽为V字形结构。

[0013]本发明与已有技术相比具有以下优点：

[0014]本发明结构简单、紧凑、合理，能够准确高效实现汽车门锁电开和回位功能，传动效率高，开启力大，动作过程停靠准确，避免发生过行程、过冲等现象；拥有电机反转保护，电机反转不会对机构带来损伤。

[0015]附图说明

[0016]图1为本发明正面结构图。

[0017]图2为限位顶杆不处于限位位置结构图。

[0018]图3为限位顶杆处于限位位置结构图。

[0019]图4为本发明背面结构图。

[0020]附图标记说明：1-电机、2-蜗杆、3-蜗轮、4-蜗轮拨杆、5-限位顶杆、6-棘爪、7-限位板、8-限位卡槽、9-推杆、10-推块、11-棘爪拨杆、12-联动块。

[0021]具体实施方式

[0022]下面本发明将结合附图中的实施例作进一步描述：

[0023]如图1~4所示，本发明主要包括电机1、蜗杆2、蜗轮3、蜗轮拨杆4、限位顶杆5、棘爪6、限位板7和棘爪拨杆11。

[0024]电机1驱动端连接蜗杆2，蜗杆2与蜗轮3啮合连接。蜗轮3侧面沿圆周方向设有至少一个联动块12，蜗轮拨杆4前端位于联动块12的转动路径上，蜗轮拨杆4后端固接拨杆转轴。拨杆转轴上固接棘爪拨杆11后端，棘爪拨杆11前端接触棘爪6并位于棘爪6转动路径上。

[0025]所述棘爪6上设有推杆9，推杆9与棘爪拨杆11前端接触。

[0026]限位顶杆5前端接触棘爪6并位于棘爪6转动路径上，限位顶杆5中部通过销轴铰接在壳体上，限位顶杆5后端延伸到蜗轮3处，并使得蜗轮3位于限位顶杆5转动路径上。

[0027]所述棘爪6上设有推块10，推块10与限位顶杆5前端接触。

[0028]所述限位顶杆5中部连接的销轴上连接扭簧，扭簧能够让限位顶杆5压紧接触棘爪6。

[0029]蜗轮3背面共轴连接限位板7，限位板7上沿圆周方向设有至少一个V字形结构的限位卡槽8，限位顶杆5能够卡入限位卡槽8中实现开锁状态的锁定。

[0030]本发明的工作原理是：当电机收到一个解锁信号后，电机开始转动带动蜗杆转动，蜗杆带动蜗轮顺时针转动。蜗轮上的联动块带动蜗轮拨杆和棘爪拨杆转动，棘爪拨杆推动棘爪实现解锁。在蜗轮转动的同时，限位顶杆脱离棘爪，在扭簧回位力作用下，限位顶杆逆时针旋转，使限位顶杆始终靠在蜗轮的限位板侧面。当蜗轮转到一定角度后，限位顶杆会顶在蜗轮的限位卡槽里，实现电机\蜗轮准停，至此一个电开过程结束。限位顶杆和蜗轮推杆在棘爪回位力的作用下带动回位，实现机构的复位。

[0031]本发明结构简单、紧凑、合理，能够准确高效实现汽车门锁电开和回位功能，传动效率高，开启力大，动作过程停靠准确，避免发生过行程、过冲等现象；拥有电机反转保护，电机反转不会对机构带来损伤。
