执行器组件包括执行器壳体201、执行器盖板202、蜗轮203、电机204、 蜗杆205、手动开启连杆206、螺母208、手动开启连杆扭簧209、电动开启连杆210、电动开启连杆扭簧211、螺母复位开关212、锁舌开关213、棘爪开关214、手动复位拉杆215、第一连接螺钉216、第二连接螺钉217、锁体壳体101和底板104，执行器壳体201、锁体壳体101与底板104，执行器组件只含有一个电机，通过第一连接螺钉216和第二连接螺钉217连接，执行器壳体201与执行器盖板202通过卡扣连接，执行器盖板202内设有电器连接组件，锁舌开关213、棘爪开关214和电机204端子与门锁接插件连接，电机204的输出轴连接有蜗杆205，蜗杆205传动连接有蜗轮203，蜗轮203的一端设有与蜗杆205啮合的齿形，另一端设有与螺母208啮合的丝杠，蜗轮203的中心固定在执行器壳体201和执行器盖板202中间，通过蜗轮203两端部的外圆中心定位从而绕固定轴旋转，螺母208在蜗轮203的丝杠端移动，同时螺母208限位在执行器壳体201中，使螺母208只能绕直线运动而不翻转，螺母208移动过程中，带动电动开启连杆210旋转，电动开启连杆210带动锁体组件的棘爪105，实现电动解锁，螺母208往另一个方向移动时，带动吸合第一拉杆111，实现电动吸合。
优选的，蜗轮203上设有丝杠。
优选的，螺母复位开关212设置在执行器盖板202上。
优选的，手动复位拉杆215与吸合第一拉杆111直接连接，操作手动复位拉杆215与吸合第一拉杆111连接。
优选的，手动开启连杆206为一种可用于手动解锁的构件。
优选的，吸合第一拉杆111与吸合第二拉杆112通过在不同的位置形成不同的四连杆机构的角度。
优选的，锁舌103设有三个锁位。
优选的，锁舌103设有凸起结构，凸起结构与棘爪释放件107配合连接。
优选的，锁舌开关拉杆110与锁舌103通过卡接的方式连接。
参考图3，蜗轮203上具有丝杠，蜗轮203与丝杠为同一零件，跟随蜗轮203同时旋转，丝杠旋转带动螺母208移动，螺母208往一个方向移动时，与吸合第一拉杆111接触，带动吸合第一拉杆111转动，从而实现电动吸合。螺母208往另一个方向移动时，与电动开启连杆210接触，实现电动开启。
参考图4，螺母208通过双向运动实现了同一电机的电动吸合和电动开启的操作，螺母208往任何一个方向运动后，都会回到初始位置，回到初始位置时，螺母复位开关212被按下，往任何一个方向运动一定的行程后，螺母复位开关212会被松开，复位开关212将会有按下和松开的状态，而复位开关212设置在执行器盖板202上，将开关的状态通过电器连接组件从门锁的接插头端输出不同位置的开关信号状态指示。
参考图5，手动复位拉杆215与吸合第一拉杆111直接连接，当汽车电瓶断电或者因为系统故障，吸合第一拉杆111无法复位时，操作手动复位拉杆215可将吸合第一拉杆111复位，从而使吸合第二拉杆112与锁舌103脱开，从而实现锁舌103的释放。
参考图6，手动开启连杆206可与棘爪释放件107或电动开启连杆210接触，当汽车断电或者系统故障无法电动开启时，可操作手动开启连杆206实现手动开启。
参考图7，吸合第一拉杆111与吸合第二拉杆112在不同位置相互作用时，会形成不同的相互位置关系，从而得到不同的力臂产生不同的输出效率实现了电动吸合。
参考图8，锁舌103有三个锁位，分别为第三锁位，第二锁位和第一锁位，当车门从全开到第三锁位时，因为锁舌开关213的信号跳变，可作为电动吸合的触发信号，启动电动吸合，实现了在第三个锁位开始电动吸合的功能。
参考图9，锁舌103有一凸起结构，该凸起结构与棘爪释放件107配合，棘爪释放件107从门开到门锁处于第一锁位前，都被限位在锁舌103的凸起 结构上，从在门锁到达第一锁位时，锁舌103的凸起结构发生形状变化，棘爪释放件107不再被限位在锁舌103的凸起结构上，实现了棘爪释放件107仅在棘爪105到达第一锁位时松开棘爪开关214，其余时间均按下棘爪开关214。
参考图10，锁舌开关拉杆110与锁舌103之间通过卡接的方式在安装到铆钉之前卡接在一起，实现在门锁的生命周期内保持连接的状态，使锁舌开关拉杆110与锁舌103的同步运动，通过锁舌开关拉杆110触发锁舌开关213，实现了锁舌103处于不同位置时锁舌开关213处于不同的状态，而锁舌开关213设置在执行器盖板202上，将开关的状态通过电器连接组件从门锁的接插头端输出不同位置的开关信号状态指示。
基于上述，本发明的优点在于，使用一个电机实现了背门锁的电动吸合和电动开启，该背门锁可配合电动举升门系统的其他执行部件实现电动的开关汽车的后背门，无需手动操作，使用方便，且提升用户的体验效果，提升了汽车的整体价值。该背门锁除了电动吸合和电动开启功能外，还具备手动开启、手动关门和手动复位的功能，即使汽车电瓶没电或者故障情况下，可以使用手动的方式开关门和复位，提高了系统的安全性和可靠。
