Description

驱动构件
技术领域
本公开涉及一种驱动构件，所述驱动构件包括具有纵向轴线并且在致动端具有齿轮机构的电机、承载位移杆的支撑构件，所述位移杆可移动地安装在支撑构件上。
本公开还涉及一种车辆，所述车辆包括具有靠背的座椅，所述靠背能够经由这样的驱动构件调整。
背景技术
具有能够通过驱动构件调整的可枢转的后部座椅部分的机动车辆是已知的。驱动构件具有电机，电机在其输出轴处包括减速齿轮机构。齿轮机构经由位于输出转换机构的壳体中的蜗轮驱动螺纹心轴。心轴在座椅框架的方向延伸，同时电机驱动装置在靠背的平面中以其轴线横向于心轴地取向。
已知的驱动机构具有比较重的结构，以便吸收作用在其上的力。此外，驱动构件与座椅和与车辆的刚性连接需要小的公差，并且在调整座椅期间当驱动构件与座椅之间的角度改变时受到应力。此外，在发生事故的情况下，从靠背传递到驱动机构的力的方向可能导致驱动机构变形。
本公开的一个目的是提供一种减轻重量的驱动构件。进一步的目的是提供一种驱动构件，该驱动构件允许连接部件中更大的公差并且在这些部件的调整过程中保持其功能。再一个目的是提供一种用于调整车辆中的靠背的驱动构件，其在向后碰撞期间提供改进的安全性。
发明内容
根据本公开的驱动构件包括通过其致动端连接到支撑构件的电机、包括铰接构件的齿轮机构，该铰接构件允许位移杆绕着横向于纵向轴线取向的枢转轴线枢转，齿轮机构与位移杆接合，支撑构件通过能绕着横向于纵向轴线的轴线铰接的铰接连接部铰接地附接到固定支架。
电机和位移杆的铰接支撑以及通过齿轮机构允许的位移杆的枢转运动，确保该杆在运动方向上适当地对准，并确保实现有效的推拉运动。这导致驱动构件的重量减轻，其可能小于已知驱动构件的重量的一半。此外，根据本公开的驱动构件的自对准允许在附接到驱动构件的结构例如靠背和车辆框架中具有更大的公差。在调整被连接部件的位置期间，或者在驱动构件安装在车辆中的情况下发生碰撞期间，根据本公开的驱动构件保持与运动方向对准并在位移方向施加有效的推拉力。
位移杆可以沿着电机在纵向轴线的方向上延伸以提供紧凑的驱动构件。
驱动构件可以具有固定支架，固定支架包括具有中心开口的板状本体，在每个相对的边缘处，中心开口具有横向于本体平面的凸缘，凸缘承载支撑构件。
通过驱动构件在固定支架的开口中枢转来获得位移杆的适当对准，齿轮机构容纳在该开口中。
电机可以位于板状本体的第一侧处，位移杆经由开口延伸到本体的第二侧并且在该侧设置有可动接头。
电机和位移杆在固定支架的相应侧上延伸，其可以被安装成调整车辆中座椅的靠背，而无需位于靠背的平面中的多个部分。
在一个实施例中，位移杆在电机一侧包括自由端，该自由端不设置用于使杆与推力和拉力的方向适当对准的附接装置。
一种包括具有能够绕着下部枢转轴线枢转的靠背的座椅的车辆可以包括根据本公开的驱动构件，固定支架连接到车辆的框架部分并且位移杆附接到靠背的上部部分。该座椅可以是后部座椅。
驱动构件的重量减轻导致燃料消耗减少。电机和位移杆横向于座椅平面的放置确保没有部件与后部支撑表面相互作用。此外，位移杆与调整后的座椅位置的对准导致平稳操作，并且在来自后部的冲击期间，力从靠背适当地传递到车辆框架。
附图说明
将参照附图以非限制性示例的方式详细描述驱动构件的实施例。
在附图中：
图1示出了根据本公开的驱动构件的透视图，
图2示出了对于位移杆的不同位置，图1的驱动构件的侧视图，
图3示出了图1的驱动构件的俯视截面图，
图4示出了位移杆绕着枢转轴线的枢转运动的俯视图，
图5示出了图1的驱动构件的齿轮机构的截面侧视图，以及
图6示出了连接到机动车辆的后部座椅的靠背的根据本公开的驱动构件。
具体实施方式
图1示出了根据本公开的驱动构件1，驱动构件1包括具有纵向轴线3的电机2。电机2在其致动端5处连接到支撑构件6。齿轮机构被容纳在齿轮箱9中并且驱动可滑动地安装在支撑构件6中的位移杆7。支撑构件6连接到固定支架8，使得其能够绕着横向于纵向轴线3取向的轴线10枢转。
位移杆7在其外表面上包括带齿面，该带齿面与齿轮箱9中的齿轮机构啮合，用于使杆在其长度方向上位移。在其附接端上，杆7包括可动接头13。在杆7的自由端14处，没有设置连接构件。
固定支架8包括具有中心开口11的板状本体，位移杆7延伸穿过中心开口11。支架8的两个侧部12、12'被设置用于连接到例如车辆的框架部分。
图2示出了驱动构件1的侧视图，其中支架8的凸缘15是可见的，其经由承载齿轮箱9的支撑构件6上的短柱16以铰接方式承载电机2。通过铰接在支架8中，位移杆能够占据虚线指示的位置。位移杆可以绕枢转轴线4枢转。
图3示出了齿轮箱9与支撑构件6的连接以及支撑构件6的短柱16、16'与固定支架8的凸缘15、15'的枢转连接。齿轮箱9包括圆形铰接构件25、26，其承载位移杆7，使得它可以绕着枢转轴线4枢转。位移杆7穿过支撑构件6中的开口23、24，开口23、24为位移杆7在绕着枢转轴线4枢转期间留下足够的空间。
图4示出了当绕着枢转轴线4枢转时处于三个不同位置的位移杆。
图5示出了齿轮机构19在位移杆7的长度方向驱动位移杆7。电机2的中心齿轮20驱动传动齿轮21，传动齿轮21与围绕杆7的齿轮22相互作用。齿轮22的内部设有与杆上的凹槽相互作用的齿，从而齿轮22的旋转使杆7在其长度方向移动。
图6示出了后部座椅的靠背30，其能绕着下部铰接轴31铰接。驱动构件1的固定支架8连接到车辆的框架32。驱动构件1的可动接头13附接到靠背的上凸缘33。
在该实施例中，驱动构件1已被描述为用于调整机动车辆中后部座椅的靠背，但不限于此。根据本公开的驱动构件1能够用于调整相互连接的物体的大范围的相对位置。
