具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位 构造和操作，因此不能理解为对本发明的限制。
下面参考附图描述根据本发明实施例的车用踏杠设备和车辆。
如图1-3所示，根据本发明实施例的车辆1000包括车身200和车用踏杠设备100，车用踏杠设备100安装在车身200的底面201。换言之，车用踏杠设备100安装在车身200的底盘上。
如图1和图2所示，车辆1000包括车门300，车用踏杠设备100邻近车门300设置且位于车门300下方。在图1和图2所示的示例中，车辆1000具有两个车门300，车门300为侧门。本发明并不限于此，例如，车辆1000可以具有四个车门(侧门)300，车身200每一侧设有两个侧门300，在车身200的每一侧均设有一个车用踏杠设备100。可选地，车辆1000还可以具有尾门(未示出)，在车身200的尾部设有邻近尾门的车用踏杠设备100。
下面描述根据本发明实施例的车用踏杠设备。
如图4所示，根据本发明实施例的车用踏杠设备100包括踏杠1、伸缩装置2和锁定部件3，其中踏杠1在伸出位置和缩回位置之间可移动。
伸缩装置2包括安装支座21、踏杠支座22和臂组件23。踏杠1安装在踏杠支座22上，臂组件23分别与安装支座21和踏杠支座22可枢转地相连以驱动踏杠1在伸出位置和缩回位置之间移动。换言之，臂组件23的一端与安装支座21可枢转地相连，臂组件23的另一端与踏杠支座22可枢转地相连，臂组件23在驱动装置例如电机的驱动下带动踏杠1在伸出位置和缩回位置之间移动。具体地，安装支座21可以安装在车身200的底面201。
锁定部件3可接合踏杠1和踏杠支座22中的一个且与踏杠1和踏杠支座22中的所述一个可脱离，其中在缩回位置，锁定部件3接合踏杠1和踏杠支座22中的一个以将踏杠1锁定在缩回位置。在一个实施例中，锁定部件3直接与踏杠1接合和与踏杠1脱离，具体地，在踏杠1移动到缩回位置时，锁定部件3接合踏杠1以将踏杠1锁定在缩回位置，锁定部件3与踏杠1脱离，以允许踏杠1从缩回位置朝向伸出位置移动。在另一个实施例中，踏杠1安装在踏杠支座22上，锁定部件3与踏杠支座22接合和脱离，以实现锁定部件3对踏杠1锁定和释放，以通过接合踏杠支座22而将踏杠1锁定在缩回位置，锁定部件3与踏杠支座22脱离，以允许踏杠支座22带动踏杠1从缩回位置朝向伸出位置移动。
这里，需要理解的是，锁定部件3可以在踏杠1离开缩回位置之前释放踏杠1或踏杠支座22，也可以在踏杠1离开缩回位置同时释放踏杠1或踏杠支座22，即踏杠1或踏杠支座22脱离锁定部件3的过程可以与踏杠1离开缩回位置的过程同时进行。
在一些实施例中，在缩回位置，踏杠1贴靠在车身200的侧面的下沿处。例如踏杠1沿竖直方向定向且贴靠在车身200的侧面的下沿处，由此踏杠1盖住车身200的下沿。
在另一些实施例中，在缩回位置，踏杠1倾斜地贴靠在车身200的底面201与车身200 的侧面的交界处。换言之，踏杠1相对于车身200的侧面倾斜设置，且贴靠在车身的底面201和车身200的侧面的交界处，由此踏杠1可以盖住车身的底面201的外沿和车身200的侧面的下沿。由此，通过锁定部件3在缩回位置锁定踏杠1，踏杠1可以用作车辆的保险杠而起到防护功能，以保护车身以防止车辆1被撞击或刮蹭。
根据本发明实施例的车用踏杠设备，通过锁定部件3将处于缩回位置的踏杠1锁定在缩回位置，提高了踏杠1在缩回位置的稳定性，并且通过锁定部件3锁定和支撑踏杠1，在踏杠1受到外力冲击时可以避免损坏伸缩装置，而且在缩回位置该踏杠1可以用作车辆的保险杠，起到一定的防护功能，避免车辆被撞击或刮蹭。
在一些实施例中，踏杠1从缩回位置朝向伸出位置移动时，踏杠1和踏杠支座22中的一个克服锁定部件3的锁定力而与锁定部件3脱离。
在一些实施例中，踏杠1和踏杠支座22中的一个具有接合部件4，锁定部件3可接合且可脱离接合部件4。换言之，踏杠1具有接合部件4，或者踏杠支座22具有接合部件4，踏杠1移动到缩回位置时，锁定部件3与接合部件4可接合以将踏杠1锁定在缩回位置，当踏杠1离开缩回位置朝向伸出位置移动时，锁定部件3和接合部件4脱离，即锁定部件3释放踏杠1，以便踏杠1能够从缩回位置向伸出位置移动。
如图1所示，当车门300打开时，锁定部件3与接合部件4脱离开，且伸缩装置2驱动踏杠1移动到伸出位置，人们可以通过踏杠1上车。如图2所示，当车门300关闭时，伸缩装置2驱动踏杠1向缩回位置移动，踏杠1移动到缩回位置时，锁定部件3与接合部件4接合以锁定踏杠1。可以理解的是，在一些实施例中，在踏杠1移动到缩回位置后锁定部件3与接合部件4接合以锁定踏杠1，在另一些实施例中，在踏杠1朝向缩回位置移动的过程中踏杠1同时逐渐进入被锁定部件3锁定的位置并且在踏杠1移动到缩回位置时锁定部件3完成对踏杠1的锁定。
在一些实施例中，接合部件4与踏杠1或踏杠支座22的连接方式不受限制，例如，接合部件4可拆卸地连接在踏杠1或踏杠支座22上，或者接合部件4与踏杠1或踏杠支座22一体形成。例如图4所示，接合部件4设在踏杠1上，且接合部件4与踏杠1一体形成。其中，当接合部件4与踏杠1可拆卸地连接时，接合部件4与踏杠1可以看作彼此不同的独立部件，当接合部件4与踏杠1一体形成时，接合部件4与踏杠1可以看作一个整体。
在一些具体示例中，如图4-8所示，接合部件4包括接合轴41，锁定部件3包括锁定座31。锁定座31具有锁定槽312，接合轴41可接合在锁定槽312内且可脱离锁定槽312。
具体地，踏杠1通过锁定槽312对接合轴41的卡持力被锁定在缩回位置，其中在踏杠1从缩回位置朝向伸出位置移动时，接合轴41克服锁定槽312的卡持力而与锁定槽312脱离。
换言之，在踏杠1移动到缩回位置时，如图6、8所示，接合部件4的接合轴41接合在锁定座31上的锁定槽312内，且通过锁定槽312对接合轴41的卡持力将踏杠1锁定在缩回位置。当需要踏杠1从缩回位置朝向伸出位置移动时，接合轴41克服锁定槽312的锁定力而与锁定槽312脱离，以允许踏杠1从缩回位置向伸出位置移动，进而便于踏杠1移动到伸出位置，如图5、7所示。可以理解的是，当踏杠1朝向缩回位置移动时，当踏杠1移动到预定位置，接合轴41开始进入锁定槽312，随着踏杠1进一步朝向缩回位置移动，接合轴41逐渐进入锁定槽312，当踏杠1移动到缩回位置时，接合轴41全部进入锁定槽312，即接合轴41完全接合锁定槽312内，以实现对踏杠1的锁定。反之，当踏杠1从缩回位置朝向伸出位置逐渐移动时，接合轴41逐渐从锁定槽312出来，当踏杠1从缩回位置移动到预定位置时，接合轴41全部离开锁定槽312，从而释放踏杠1。
在一些实施例中，接合部件4还包括第一支撑耳42和第二支撑耳43，第一支撑耳42和第二支撑耳43彼此间隔开地设置，接合轴41的第一端与第一支撑耳42相连，接合轴41的第二端与第二支撑耳43相连，接合部件4设在踏杠1上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠1上，接合部件4设在踏杠支座22上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠支座22上。
这里，需要理解的是，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。
具体地，第一支撑耳42的第一端和第二支撑耳43的第二端设在踏杠1或是踏杠支座22上，且第一支撑耳42的第二支撑耳43彼此相对且彼此间隔设置，第一支撑耳42的第二端和第二支撑耳43的第二端之间连接有接合轴41，接合轴41的第一端与第一支撑耳42的第二端相连，接合轴41的第二端与第二支撑耳42的第二端相连。接合轴41可接合且可脱离锁定部件3。
在一些实施例中，锁定座31安装在车身200的底部，锁定座31具有向下延伸的延伸臂部311，锁定槽312设在延伸臂部311的自由端3111的端面上，即设在延伸臂部311的自由端面上。如图4所示，由于延伸臂部311从锁定座31的底部向下延伸，延伸臂部311的自由端面即为延伸臂部311的下端面，也就是说，锁定槽312设在延伸臂部311的下端面上。
在一些优选实施例中，接合轴41的横截面的外周轮廓与锁定槽312的内周轮廓相适配，以使接合轴41更好地接合在锁定槽312内。具体地，接合轴41的横截面为非圆形，锁定槽312的内周轮廓也为非圆形，例如四边形、六边形等的多边形，其中图4-6示出了接合轴41的外周轮廓和锁定槽312的内周轮廓为正六边形，图7-8中示出了接合轴41的外周 轮廓和锁定槽312的内周轮廓为梯形。可以理解的是，接合轴41的横截面并不限于此。
在一些实施例中，锁定座31与安装支座21相连。换言之，锁定座31可以看作与安装支座21为不同的部件。在另一些实施例中，锁定座31与安装支座21一体形成。换言之，锁定座31和安装支座21可以看作一个整体部件。
具体地，如图4-6所示，安装支座21和锁定座31沿左右方向依次相连且设在车身200的底面201，安装支座21的下端与臂组件23的上端可枢转地相连，臂组件23的下端与踏杠支座22的上端可枢转地相连，踏杠1设在踏杠支座22的下端。锁定座31具有向下延伸的延伸臂部311，延伸臂部311的自由端3111的端面设有锁定槽312，锁定槽312的内周轮廓为正六边形。
接合部件4包括接合轴41、第一支撑耳42和第二支撑耳43，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠1的邻近锁定座3的一侧，接合轴41的第一端与第一支撑耳42相连，接合轴41的第二端与第二支撑耳43相连，且接合轴41的外周轮廓为正六边形。如图6所示，接合轴41接合在锁定槽312内以使踏杠1通过锁定槽312对接合轴41的卡持力被锁定在缩回位置，在踏杠1从缩回位置朝向伸出位置移动时，接合轴41克服锁定槽312的卡持力而与锁定槽312脱离，以便踏杠1移动到伸出位置，如图5所示。
可选地，图7-8所示，接合轴41的外周轮廓和锁定槽312的内周轮廓均为梯形，其中如图8所示，接合轴41接合在锁定槽312内以使踏杠1通过锁定槽312对接合轴41的卡持力被锁定在缩回位置，在踏杠1从缩回位置朝向伸出位置移动时，接合轴41克服锁定槽312的卡持力而与锁定槽312脱离，以便踏杠1移动到伸出位置，如图7所示。
可以理解的是，接合部件4并不限于接合轴的形式。在另一些可选的实施例中，如图9所示，接合部件4可以为接合凸起401，该接合凸起401可接合在锁定槽312内且可脱离锁定槽312。具体地，接合凸起401设在踏杠1或踏杠支座22上，且接合凸起401与踏杠1或踏杠支座22的连接方式不受限制，例如，接合凸起401可拆卸地安装在踏杠1或踏杠支座22上，或者，接合凸起401与踏杠1或踏杠支座22一体形成。
接合凸起401的外周轮廓与锁定槽312的内周轮廓相适配，踏杠1移动到缩回位置时，接合凸起401能够接合锁定槽312内，以将踏杠1锁定在缩回位置。接合凸起401可与锁定槽312脱离，以便允许踏杠1从缩回位置朝向伸出位置移动。
在一些实施例中，伸缩装置2、锁定部件3和接合部件4均为多个。多个伸缩装置2、多个锁定部件3和多个接合部件4一一对应，以进一步提高驱动踏杠1在运动和/或静止时的稳定性。在一些实施例中，通过设置多个伸缩装置2、多个锁定部件3和多个接合部件4，进一步提高了踏杠1在缩回位置的稳定性以及运动过程中的平稳性。这里，需要理解的是，术语“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在一些具体实施例中，如图3所示，每个锁定部件3位于与其对应的伸缩装置2沿踏杠1的长度方向(图3所示的左右方向)的外侧。可选地，锁定部件3也可以设在对应伸缩装置2的内侧。
具体地，如图1-3所示，车辆1000上的车用踏杠设备100包括两个伸缩装置2、两个锁定部件3和两个接合部件4，接合部件4设在踏杠1上，锁定部件3设在车身200的底部，伸缩装置2连接车身200的底部和踏杠1。其中一个接合部件4、一个伸缩装置2、另一个伸缩装置2和另一个接合部件4沿踏杠1的长度方向(图3所示左右方向)依次间隔布置，且一个接合部件4邻近一个伸缩装置2，另一个接合部件4邻近另一个伸缩装置2。
其中一个锁定部件3和另一个锁定部件3在车身200的底面201沿踏杠1的长度方向间隔布置，且一个锁定部件3和一个接合部件4均位于一个伸缩装置2的左侧，且一个锁定部件3和一个接合部件4相对设置。另一个锁定部件3和另一个接合部件4均位于另一个伸缩装置2的右侧，且另一个锁定部件3和另一个接合部件4相对设置。在缩回位置，两个接合部件4对应地可接合两个锁定部件3且可脱离两个锁定部件3。
下面描述根据本发明另一实施例的车用踏杠设备。
如图1-9所示，根据本发明实施例的车用踏杠设备100包括踏杠1、伸缩装置2和锁定部件3，其中踏杠1在伸出位置和缩回位置之间可移动。伸缩装置2与踏杠1相连，用于驱动踏杠1在伸出位置和缩回位置之间移动。
锁定部件3用于将踏杠1锁定在缩回位置且允许踏杠1离开缩回位置朝向伸出位置移动。换言之，踏杠1在缩回位置时，锁定部件3可将踏杠1锁定在缩回位置，以提高踏杠1的稳定性。而且，在缩回位置，踏杠1由锁定部件3锁定，锁定部件3还起到支撑踏杠1的作用，由此，即使踏杠1受到外力冲击，也不会损坏伸缩装置2，从而提高了伸缩装置2的寿命。踏杠1从缩回位置朝向伸出位置移动时，锁定部件3可允许伸缩装置2驱动踏杠1向伸出位置移动。
下面描述根据本发明再一实施例的车用踏杠设备。
如图1-9所示，根据本发明实施例的车用踏杠设备100包括踏杠1、伸缩装置2和锁定部件3，其中踏杠1在伸出位置和缩回位置之间可移动。伸缩装置2与踏杠1相连，用于驱动踏杠1在伸出位置和缩回位置之间移动。
锁定部件3可接合踏杠1以将踏杠1锁定在缩回位置，且可脱离踏杠1以允许踏杠1从缩回位置朝向伸出位置移动。换言之，踏杠1在缩回位置时，锁定部件3可接合踏杠1以将踏杠1锁定在缩回位置，从而提高踏杠1的稳定性。而且，在缩回位置，踏杠1由锁定部件3锁定，锁定部件3还起到支撑踏杠1的作用，由此，即使踏杠1受到外力冲击，也不会损坏伸缩装置2，从而提高了伸缩装置2的寿命。踏杠1从缩回位置朝向伸出位置 移动时，锁定部件3与踏杠1可脱离以允许伸缩装置2驱动踏杠1向伸出位置移动。
这里，需要理解的是，锁定部件3可以在踏杠1离开缩回位置之前脱离踏杠1，也可以在踏杠1离开缩回位置同时脱离踏杠1，即踏杠1脱离锁定部件3的过程可以与踏杠1离开缩回位置的过程同时进行。
在一些实施例中，踏杠1在从缩回位置朝向伸出位置移动时，踏杠1克服锁定部件3的锁定力而与锁定部件3脱离。
下面描述根据本发明另一些实施例的车用踏杠设备。
如图4-8所示，根据本发明实施例的车用踏杠设备100包括安装支座21、踏杠支座22、踏杠1、臂组件23、接合轴41和锁定座31，其中踏杠1安装在踏杠支座22上，臂组件23分别与安装支座21和踏杠支座22可枢转地相连以驱动踏杠1在伸出位置和缩回位置之间移动。换言之，臂组件23的一端与安装支座21可枢转地相连，臂组件23的另一端与踏杠支座22可枢转地相连，臂组件23在驱动装置例如电机的驱动下带动踏杠1在伸出位置和缩回位置之间移动。具体地，安装支座21可以安装在车身200的底面201。
接合轴41安装在踏杠1或踏杠支座22上，锁定座31具有锁定槽312，接合轴41可接合在锁定槽312内且可脱离锁定槽312，其中在缩回位置，接合轴41接合在锁定槽312内以将踏杠1锁定在缩回位置，接合轴41在踏杠1从缩回位置朝向伸出位置移动时脱离锁定槽3。
如图1所示，当车门300打开时，锁定槽312与接合轴41脱离开，且臂组件23驱动踏杠1移动到伸出位置，人们可以通过踏杠1上车。如图2所示，当车门300关闭时，臂组件23驱动踏杠1向缩回位置移动，踏杠1移动到缩回位置时，锁定槽312与接合轴41接合以锁定踏杠1。可以理解的是，在一些实施例中，在踏杠1移动到缩回位置后锁定槽312与接合轴41接合以锁定踏杠1，在另一些实施例中，在踏杠1朝向缩回位置移动的过程中接合轴41同时逐渐进入被锁定槽312锁定的位置并且在踏杠1移动到缩回位置时锁定槽312与接合轴41完成对踏杠1的锁定。
具体地，踏杠1通过锁定槽312对接合轴41的卡持力被锁定在缩回位置，其中在踏杠1从缩回位置朝向伸出位置移动时，接合轴41克服锁定槽312的卡持力而与锁定槽312脱离。
换言之，在踏杠1移动到缩回位置时，如图6和图8所示，接合部件4的接合轴41接合在锁定座31上的锁定槽312内，且通过锁定槽312对接合轴41的卡持力将踏杠1锁定在缩回位置。当需要踏杠1从缩回位置朝向伸出位置移动时，接合轴41克服锁定槽312的锁定力而与锁定槽312脱离，以允许踏杠1从缩回位置向伸出位置移动，进而便于踏杠1移动到伸出位置，如图5、7所示。可以理解的是，当踏杠1朝向缩回位置移动时，当踏杠 1移动到预定位置，接合轴41开始进入锁定槽312，随着踏杠1进一步朝向缩回位置移动，接合轴41逐渐进入锁定槽312，当踏杠1移动到缩回位置时，接合轴41全部进入锁定槽312，即接合轴41完全接合锁定槽312内，以实现对踏杠1的锁定。反之，当踏杠1从缩回位置朝向伸出位置逐渐移动时，接合轴41逐渐从锁定槽312出来，当踏杠1从缩回位置移动到预定位置时，接合轴41全部离开锁定槽312，从而释放踏杠1。
根据本发明实施例的车用踏杠设备，通过接合轴41和锁定槽312将处于缩回位置的踏杠1锁定在缩回位置，提高了踏杠1在缩回位置的稳定性，并且通过接合轴41和锁定槽312锁定和支撑踏杠1，在踏杠1受到外力冲击时可以避免损坏伸缩装置，而且在缩回位置该踏杠1可以用作保险杠，起到对车辆的防护功能。
在一些实施例中，在缩回位置，踏杠1贴靠在车身200的侧面的下沿处。例如踏杠1沿竖直方向定向且贴靠在车身200的侧面的下沿处，由此踏杠1盖住车身200的下沿。
在另一些实施例中，在缩回位置，踏杠1倾斜地贴靠在车身200的底面201与车身200的侧面的交界处。换言之，踏杠1相对于车身200的侧面倾斜设置，且贴靠在车身的底面201和车身200的侧面的交界处，由此踏杠1可以盖住车身的底面201的外沿和车身200的侧面的下沿。由此，通过锁定部件3在缩回位置锁定踏杠1，踏杠1可以用作车辆的保险杠而起到防护功能，以保护车身以防止车辆1被撞击或刮蹭。
在一些实施例中，接合轴41的横截面为非圆形，且接合轴41的横截面的轮廓与锁定槽312适配，以使接合轴41更好地接合在锁定槽312内。具体地，接合轴41的横截面的外周轮廓为非圆形，锁定槽312的内周轮廓也为非圆形，例如四边形、六边形等的多边形，其中图4-6示出了接合轴41的外周轮廓和锁定槽312的内周轮廓为正六边形，图7-8中示出了接合轴41的外周轮廓和锁定槽312的内周轮廓为梯形。可以理解的是，接合轴41的横截面并不限于此。
在一些实施例中，锁定座31具有向下延伸的延伸臂部311，锁定槽312设在延伸臂部311的自由端3111的端面上，即设在延伸臂部311的自由端面上。如图4所示，由于延伸臂部311从锁定座31的底部向下延伸，延伸臂部311的自由端面即为延伸臂部311的下端面，也就是说，锁定槽312设在延伸臂部311的下端面上。
在一些可选的实施例中，踏杠1上设有第一支撑耳42和第二支撑耳43，第一支撑耳42和第二支撑耳43间隔开，接合轴41的第一端与第一支撑耳42相连，接合轴41的第二端与第二支撑耳43相连。
具体地，如图4所示，第一支撑耳42和第二支撑耳43设在踏杠1的邻近锁定座31的一侧，且沿踏杠1的长度方向彼此间隔开，接合轴41位于第一支撑耳42和第二支撑耳43之间，接合轴41的轴向与踏杠1的长度方向大体一致且彼此间隔开，接合轴41的一端与 第一支撑耳42的邻近第二支撑耳43的一侧面相连，接合轴41的另一端与第二支撑耳43的邻近第一支撑耳42的一侧面相连。
可以理解的是，接合轴41的设置形式并不限于采用支撑耳支撑的形式，例如在另一些可选的实施例中，接合轴41螺纹安装在踏杠支座21上，从而便于接合轴41拆卸。
在一些实施例中，锁定座31与安装支座21相连。换言之，锁定座31可以看作与安装支座21为不同的部件。在另一些实施例中，锁定座31与安装支座21一体形成。换言之，锁定座31和安装支座21可以看作一个整体部件。
在一些可选的实施例中，如图10所示，臂组件23第一臂231和第二臂232。第一臂231的第一端2311与安装支座21可枢转地相连，第一臂231的第二端2312与踏杠支座22可枢转地相连，第二臂232的第一端2321与安装支座21可枢转地相连，第二臂232的第二端2322与踏杠支座22可枢转地相连。

本领域技术人员可以理解的是，第四臂234的第二端2342可以与第二臂232可枢接地相连，也可以与第三臂233可枢接地相连，还可以与第二臂232和第三臂233均可枢接地相连。
具体地，如图12所示，臂组件23还包括第一销轴235、第二销轴236、第三销轴237、第四销轴238、第五销轴239和第六销轴240。第一臂231具有上端和下端。第一臂231的通过第一销轴235可枢转地与安装支座21相连，第一臂231的下端通过第二销轴236可枢转地与踏杠支座22相连。第二臂232具有上端和下端。第二臂232的上端通过第三销轴237可枢转地与安装支座21相连。

下面参考附图描述根据本发明一些具体实施例的车用踏杠设备和车辆。
如图1-4所示，根据本发明实施例的车辆1000包括车身200、踏杠1、伸缩装置2和锁定部件3。伸缩装置2包括踏杠支座22和臂组件23，踏杠1安装在踏杠支座22上。
臂组件23分别与车身200和踏杠支座22可枢转地相连以驱动踏杠1在伸出位置和缩回位置之间移动。换言之，臂组件23的一端与车身200的底面201可枢转地相连，臂组件23的另一端与踏杠支座22可枢转地相连，臂组件23在驱动装置例如电机的驱动下带动踏杠1在伸出位置和缩回位置之间移动。可以理解的是，在该实施例中，车用踏杠设备100不包括安装支座21，臂组件23的一端直接可枢转地连接在车身200的底面201。
锁定部件3安装在车身200上，锁定部件3可接合且可脱离踏杠1和踏杠支座22中的一个，在缩回位置，锁定部件3与踏杠1和踏杠支座22中的一个接合以将踏杠1锁定在缩回位置，且在踏杠1从缩回位置朝向伸出位置移动时，锁定部件3与踏杠1和踏杠支座22中的一个脱离，以便踏杠1能够从缩回位置朝向伸出位置移动。
换言之，在一个可选的实施例中，锁定部件3直接与踏杠1可接合和可脱离，具体地，踏杠1在缩回位置时，锁定部件3可接合踏杠1以将踏杠1锁定在缩回位置；在踏杠1从缩回位置朝向伸出位置移动时，锁定部件3与踏杠1脱离。在另一个可选的实施例中，锁定部件3通过与踏杠支座22可接合和可脱离，以实现锁定部件3对踏杠1锁定和脱离。具体地，踏杠1在缩回位置，锁定部件3可接合踏杠支座221以将踏杠1锁定在缩回位置；在踏杠1从缩回位置朝向伸出位置移动时，锁定部件3与踏杠支座22脱离。
在一些实施例中，在缩回位置，踏杠1贴靠在车身200的侧面的下沿处。例如踏杠1沿竖直方向定向且贴靠在车身200的侧面的下沿处，由此踏杠1盖住车身200的下沿。
在另一些实施例中，在缩回位置，踏杠1倾斜地贴靠在车身200的底面201与车身200的侧面的交界处。换言之，踏杠1相对于车身200的侧面倾斜设置，且贴靠在车身的底面201和车身200的侧面的交界处，由此踏杠1可以盖住车身的底面201的外沿和车身200的侧面的下沿。由此，通过锁定部件3在缩回位置锁定踏杠1，踏杠1可以用作车辆的保险杠而起到防护功能，以保护车身以防止车辆1被撞击或刮蹭。
在一些实施例中，踏杠1在从缩回位置朝向伸出位置移动时，踏杠1和踏杠支座中的一个克服锁定部件3的锁定力而与锁定部件3脱离。具体地，踏杠1与锁定部件3直接可接合和脱离时，踏杠1在从缩回位置朝向伸出位置移动时，踏杠1克服锁定部件3的锁定力而与锁定部件3脱离；踏杠支座22与锁定部件3可接合和可脱离以实现踏杠1的锁定和脱离时，踏杠1在从缩回位置朝向伸出位置移动时，踏杠支座22克服锁定部件3的锁定力 而与锁定部件3脱离。
在一些实施例中，踏杠1和踏杠支座22中的一个具有接合部件4，锁定部件3可接合且可脱离接合部件4。换言之，踏杠1具有接合部件4，或者踏杠支座22具有接合部件4，踏杠1移动到缩回位置时，锁定部件3与接合部件4可接合以将踏杠1锁定在缩回位置，当踏杠1离开缩回位置朝向伸出位置移动时，锁定部件3和接合部件4脱离，即锁定部件3释放踏杠1，以便踏杠1能够从缩回位置向伸出位置移动。
如图1所示，当车门300打开时，锁定部件3与接合部件4脱离开，且伸缩装置2驱动踏杠1移动到伸出位置，人们可以通过踏杠1上车。如图2所示，当车门300关闭时，伸缩装置2驱动踏杠1向缩回位置移动，踏杠1移动到缩回位置时，锁定部件3与接合部件4接合以锁定踏杠1。可以理解的是，在一些实施例中，在踏杠1移动到缩回位置后锁定部件3与接合部件4接合以锁定踏杠1，在另一些实施例中，在踏杠1朝向缩回位置移动的过程中踏杠1同时逐渐进入被锁定部件3锁定的位置并且在踏杠1移动到缩回位置时锁定部件3完成对踏杠1的锁定。
在一些实施例中，接合部件4与踏杠1或踏杠支座22的连接方式不受限制，例如，接合部件4可拆卸地连接在踏杠1或踏杠支座22上，或者接合部件4与踏杠1或踏杠支座22一体形成。例如图4所示，接合部件4设在踏杠1上，且接合部件4与踏杠1一体形成。其中，当接合部件4与踏杠1可拆卸地连接时，接合部件4与踏杠1可以看作彼此不同的独立部件，当接合部件4与踏杠1一体形成时，接合部件4与踏杠1可以看作一个整体。
在一些具体示例中，如图4-8所示，接合部件4包括接合轴41，锁定部件3包括锁定座31。锁定座31具有锁定槽312，接合轴41可接合在锁定槽312内且可脱离锁定槽312。
具体地，踏杠1通过锁定槽312对接合轴41的卡持力被锁定在缩回位置，其中在踏杠1从缩回位置朝向伸出位置移动时，接合轴41克服锁定槽312的卡持力而与锁定槽312脱离。
换言之，在踏杠1移动到缩回位置时，如图6、8所示，接合部件4的接合轴41接合在锁定座31上的锁定槽312内，且通过锁定槽312对接合轴41的卡持力将踏杠1锁定在缩回位置。当需要踏杠1从缩回位置朝向伸出位置移动时，接合轴41克服锁定槽312的锁定力而与锁定槽312脱离，以允许踏杠1从缩回位置向伸出位置移动，进而便于踏杠1移动到伸出位置，如图5、7所示。可以理解的是，当踏杠1朝向缩回位置移动时，当踏杠1移动到预定位置，接合轴41开始进入锁定槽312，随着踏杠1进一步朝向缩回位置移动，接合轴41逐渐进入锁定槽312，当踏杠1移动到缩回位置时，接合轴41全部进入锁定槽312，即接合轴41完全接合锁定槽312内，以实现对踏杠1的锁定。反之，当踏杠1从缩回位置朝向伸出位置逐渐移动时，接合轴41逐渐从锁定槽312出来，当踏杠1从缩回位置 移动到预定位置时，接合轴41全部离开锁定槽312，从而释放踏杠1。
在一些具体地实施例中，接合轴41的横截面的外周轮廓与锁定槽312的内周轮廓相适配，以使接合轴41更好地接合在锁定槽312内。具体地，接合轴41的横截面为非圆形，锁定槽312的内周轮廓也为非圆形，例如四边形、六边形等的多边形，其中图4-6示出了接合轴41的外周轮廓和锁定槽312的内周轮廓为正六边形，图7-8中示出了接合轴41的外周轮廓和锁定槽312的内周轮廓为梯形。可以理解的是，接合轴41的横截面并不限于此。
在一些实施例中，接合部件4还包括第一支撑耳42和第二支撑耳43，第一支撑耳42和第二支撑耳43彼此间隔开地设置，接合轴41的第一端与第一支撑耳42相连，接合轴41的第二端与第二支撑耳43相连，接合部件4设在踏杠1上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠1上，接合部件4设在踏杠支座22上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠支座22上。
具体地，第一支撑耳42的第一端和第二支撑耳43的第二端设在踏杠1或是踏杠支座22上，且第一支撑耳42的第二支撑耳43彼此相对且彼此间隔设置，第一支撑耳42的第二端和第二支撑耳43的第二端之间连接有接合轴41，接合轴41的第一端与第一支撑耳42的第二端相连，接合轴41的第二端与第二支撑耳42的第二端相连。接合轴41可接合且可脱离锁定部件3。
可以理解的是，接合部件4并不限于接合轴的形式。在另一些可选的实施例中，如图9所示，接合部件4可以为接合凸起401，具体地，接合凸起401设在踏杠1或踏杠支座22上，且接合凸起401与踏杠1或踏杠支座22的连接方式不受限制，例如，接合凸起401可拆卸地安装在踏杠1或踏杠支座22上，或者，接合凸起401与踏杠1或踏杠支座22一体形成。
锁定座31具有锁定槽312，接合凸起401可接合在锁定槽312内且可脱离锁定槽312。具体地，踏杠1通过锁定槽312对接合凸起401的卡持力被锁定在缩回位置，其中在踏杠1从缩回位置朝向伸出位置移动时，接合凸起401克服锁定槽312的卡持力而与锁定槽312脱离。

如图1-9所示，根据本发明实施例的车辆1000包括车身200、踏杠1、臂组件23和锁定部件3。臂组件23分别与车身200和踏杠支座22可枢转地相连以驱动踏杠1在伸出位置和缩回位置之间移动。换言之，臂组件23的一端与车身200的底面201可枢转地相连，臂组件23的另一端与踏杠支座22可枢转地相连，臂组件23在驱动装置例如电机的驱动下带动踏杠1在伸出位置和缩回位置之间移动。

换言之，在一个可选的实施例中，锁定部件3直接与踏杠1可接合和可脱离，具体地，踏杠1在缩回位置时，锁定部件3可接合踏杠1以将踏杠1锁定在缩回位置；在踏杠1从缩回位置朝向伸出位置移动时，锁定部件3与踏杠1脱离。在另一个可选的实施例中，锁定部件3通过与踏杠支座22可接合和可脱离，以实现锁定部件3对踏杠1锁定和脱离。具体地，踏杠1在缩回位置，锁定部件3可接合踏杠支座221以将踏杠1锁定在缩回位置；在踏杠1从缩回位置朝向伸出位置移动时，锁定部件3与踏杠支座22脱离。
在一些实施例中，在缩回位置，踏杠1贴靠在车身200的侧面的下沿处。例如踏杠1沿竖直方向定向且贴靠在车身200的侧面的下沿处，由此踏杠1盖住车身200的下沿。
在另一些实施例中，在缩回位置，踏杠1倾斜地贴靠在车身200的底面201与车身200的侧面的交界处。换言之，踏杠1相对于车身200的侧面倾斜设置，且贴靠在车身的底面201和车身200的侧面的交界处，由此踏杠1可以盖住车身的底面201的外沿和车身200的侧面的下沿。由此，通过锁定部件3在缩回位置锁定踏杠1，踏杠1可以用作车辆的保险杠而起到防护功能，以保护车身以防止车辆1被撞击或刮蹭。
在一些实施例中，踏杠1在从缩回位置朝向伸出位置移动时，踏杠1和踏杠支座中的一个克服锁定部件3的锁定力而与锁定部件3脱离。具体地，踏杠1与锁定部件3直接可接合和脱离时，踏杠1在从缩回位置朝向伸出位置移动时，踏杠1克服锁定部件3的锁定 力而与锁定部件3脱离；踏杠支座22与锁定部件3可接合和可脱离以实现踏杠1的锁定和脱离时，踏杠1在从缩回位置朝向伸出位置移动时，踏杠支座22克服锁定部件3的锁定力而与锁定部件3脱离。
在一些实施例中，踏杠1和踏杠支座22中的一个具有接合部件4，锁定部件3可接合且可脱离接合部件4。换言之，踏杠1具有接合部件4，或者踏杠支座22具有接合部件4，踏杠1移动到缩回位置时，锁定部件3与接合部件4可接合以将踏杠1锁定在缩回位置，当踏杠1离开缩回位置朝向伸出位置移动时，锁定部件3和接合部件4脱离，即锁定部件3释放踏杠1，以便踏杠1能够从缩回位置向伸出位置移动。
如图1所示，当车门300打开时，锁定部件3与接合部件4脱离开，且伸缩装置2驱动踏杠1移动到伸出位置，人们可以通过踏杠1上车。如图2所示，当车门300关闭时，伸缩装置2驱动踏杠1向缩回位置移动，踏杠1移动到缩回位置时，锁定部件3与接合部件4接合以锁定踏杠1。可以理解的是，在一些实施例中，在踏杠1移动到缩回位置后锁定部件3与接合部件4接合以锁定踏杠1，在另一些实施例中，在踏杠1朝向缩回位置移动的过程中踏杠1同时逐渐进入被锁定部件3锁定的位置并且在踏杠1移动到缩回位置时锁定部件3完成对踏杠1的锁定。
在一些实施例中，接合部件4与踏杠1或踏杠支座22的连接方式不受限制，例如，接合部件4可拆卸地连接在踏杠1或踏杠支座22上，或者接合部件4与踏杠1或踏杠支座22一体形成。例如图4所示，接合部件4设在踏杠1上，且接合部件4与踏杠1一体形成。其中，当接合部件4与踏杠1可拆卸地连接时，接合部件4与踏杠1可以看作彼此不同的独立部件，当接合部件4与踏杠1一体形成时，接合部件4与踏杠1可以看作一个整体。
在一些具体示例中，如图4-8所示，接合部件4包括接合轴41，锁定部件3包括锁定座31。锁定座31具有锁定槽312，接合轴41可接合在锁定槽312内且可脱离锁定槽312。
具体地，踏杠1通过锁定槽312对接合轴41的卡持力被锁定在缩回位置，其中在踏杠1从缩回位置朝向伸出位置移动时，接合轴41克服锁定槽312的卡持力而与锁定槽312脱离。
换言之，在踏杠1移动到缩回位置时，如图6、8所示，接合部件4的接合轴41接合在锁定座31上的锁定槽312内，且通过锁定槽312对接合轴41的卡持力将踏杠1锁定在缩回位置。当需要踏杠1从缩回位置朝向伸出位置移动时，接合轴41克服锁定槽312的锁定力而与锁定槽312脱离，以允许踏杠1从缩回位置向伸出位置移动，进而便于踏杠1移动到伸出位置，如图5、7所示。可以理解的是，当踏杠1朝向缩回位置移动时，当踏杠1移动到预定位置，接合轴41开始进入锁定槽312，随着踏杠1进一步朝向缩回位置移动，接合轴41逐渐进入锁定槽312，当踏杠1移动到缩回位置时，接合轴41全部进入锁定槽 312，即接合轴41完全接合锁定槽312内，以实现对踏杠1的锁定。反之，当踏杠1从缩回位置朝向伸出位置逐渐移动时，接合轴41逐渐从锁定槽312出来，当踏杠1从缩回位置移动到预定位置时，接合轴41全部离开锁定槽312，从而释放踏杠1。
在一些实施例中，接合部件4还包括第一支撑耳42和第二支撑耳43，第一支撑耳42和第二支撑耳43彼此间隔开地设置，接合轴41的第一端与第一支撑耳42相连，接合轴41的第二端与第二支撑耳43相连，接合部件4设在踏杠1上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠1上，接合部件4设在踏杠支座22上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠支座22上。
具体地，第一支撑耳42的第一端和第二支撑耳43的第二端设在踏杠1或是踏杠支座22上，且第一支撑耳42的第二支撑耳43彼此相对且彼此间隔设置，第一支撑耳42的第二端和第二支撑耳43的第二端之间连接有接合轴41，接合轴41的第一端与第一支撑耳42的第二端相连，接合轴41的第二端与第二支撑耳42的第二端相连。接合轴41可接合且可脱离锁定部件3。
可以理解的是，接合部件4并不限于接合轴的形式。在另一些可选的实施例中，如图9所示，接合部件4可以为接合凸起401，具体地，接合凸起401设在踏杠1或踏杠支座22上，且接合凸起401与踏杠1或踏杠支座22的连接方式不受限制，例如，接合凸起401可拆卸地安装在踏杠1或踏杠支座22上，或者，接合凸起401与踏杠1或踏杠支座22一体形成。
锁定座31具有锁定槽312，接合凸起401可接合在锁定槽312内且可脱离锁定槽312。具体地，踏杠1通过锁定槽312对接合凸起401的卡持力被锁定在缩回位置，其中在踏杠1从缩回位置朝向伸出位置移动时，接合凸起401克服锁定槽312的卡持力而与锁定槽312脱离。
下面参考附图1-3和图13-20描述根据本发明一些具体实施例的车用踏杠设备和车辆。
如图1-3所示，根据本发明实施例的车辆1000包括车身200和车用踏杠设备100，车用踏杠设备100安装在车身200的底面201。换言之，车用踏杠设备100安装在车身200的底盘上。
如图13-15所示，根据本发明实施例的车用踏杠设备100包括踏杠1、伸缩装置2、锁定座31和锁定摆臂32，其中踏杠1在伸出位置和缩回位置之间可移动。
伸缩装置2包括安装支座21、踏杠支座22和臂组件23。踏杠1安装在踏杠支座22上，臂组件23分别与安装支座21和踏杠支座22可枢转地相连以驱动踏杠1在伸出位置和缩回位置之间移动。换言之，臂组件23的一端与安装支座21可枢转地相连，臂组件23的另一端与踏杠支座22可枢转地相连，臂组件23在驱动装置例如电机的驱动下带动踏杠1在伸 出位置和缩回位置之间移动。具体地，安装支座21可以安装在车身200的底面201。
锁定摆臂32在锁定位置和释放位置之间可摆动，其中在锁定位置，锁定摆臂32和锁定座31将踏杠1锁定在缩回位置；在释放位置，锁定摆臂32和锁定座31释放踏杠1，以便踏杠1能够从缩回位置朝向伸出位置移动。
在一些实施例中，在踏杠1离开缩回位置朝向伸出位置移动之前，锁定摆臂32从锁定位置转动到释放位置。换言之，当踏杠1需要从缩回位置朝向伸出位置移动之前，锁定摆臂32先从锁定位置转动到释放位置，以释放接合部件4，从而臂组件23带动踏杠1从图18所示的缩回位置移动到图16所示的伸出位置。
在一些实施例中，释放位置包括最大释放位置和最小释放位置，最小释放位置位于锁定位置与最大释放位置之间。具体地，如图18所示，踏杠1在缩回位置，锁定摆臂32在锁定位置，锁定摆臂32和锁定座31将接合部件4夹持在锁定摆臂32和锁定座31之间以锁定踏杠1。如图17所示，锁定摆臂32从锁定位置向右转动到最小释放位置，接合部件4脱离锁定摆臂32和锁定座31的夹持，即接合部件4被释放，且踏杠1移动到伸出位置和缩回位置之间的中间位置。随后，如图16所示，锁定摆臂32从最小释放位置向右继续转动到达最大释放位置，且踏杠1从中间位置移动到伸出位置。
锁定摆臂32的转动和臂组件23的伸缩运动之间的相互关系为：
在一些实施例中，在踏杠1离开缩回位置朝向伸出位置移动之前，锁定摆臂32从锁定位置转动到最小释放位置，且在锁定摆臂从最小释放位置转动到最大释放位置的同时，踏杠1从缩回位置移动到伸出位置。
在一些实施例中，踏杠1还具有位于缩回位置与伸出位置之间的中间位置，在踏杠1离开缩回位置朝向伸出位置移动之前，锁定摆臂32从锁定位置转动到最小释放位置，其中在锁定摆臂32从最小释放位置转动到最大释放位置的同时，踏杠1从缩回位置移动到中间位置，其中在踏杠1从中间位置移动到伸出位置的过程中，锁定摆臂32在最大释放位置静止不动。
可以理解的是，除了锁定摆臂32和踏杠1的运动之外，还可以是，首先锁定摆臂32从锁定位置转动到最小释放位置。
其次踏杠1从缩回位置移动到中间位置，即锁定摆臂32转动到最小释放位置后停留一段时间，且在该段时间内，踏杠1从缩回位置移动到中间位置，在该段时间结束的时刻，踏杠1处于伸出位置与缩回位置之间的中间位置，且锁定摆臂32处于最大释放位置与锁定位置之间的最小释放位置，例如图17所示。
再次，踏杠1从中间位置移动到伸出位置，锁定摆臂32从最小释放位置转动到最大释放位置，该过程中踏杠1的移动和锁定摆臂32的转动可以同时进行，也可以踏杠1先移动， 锁定摆臂32再转动，还可以锁定摆臂32先转动，踏杠1再移动。
在一些实施例中，踏杠1在缩回位置贴靠在车身200的侧面的下沿处，例如踏杠1沿竖直方向定向且贴靠在车身200的侧面的下沿处，由此踏杠1盖住车身200的下沿。在另一些实施例中，踏杠1倾斜地贴靠在车身的底面201与车身200的侧面的交界处，换言之，踏杠1相对于车身200的侧面倾斜设置，且贴靠在车身的底面201和车身200的侧面的交界处，由此踏杠1可以盖住车身的底面201的外沿和车身200的侧面的下沿。由此，通过锁定部件3在缩回位置锁定踏杠1，踏杠1可以用作车辆的保险杠而起到防护功能，以保护车身，以防止车辆1被撞击或刮蹭。
在一些实施例中，踏杠1和踏杠支座22中的一个具有接合部件4，在缩回位置，锁定摆臂32和锁定座32将接合部件4夹持它们之间以锁定踏杠1。换言之，踏杠1具有接合部件4，或者踏杠支座22具有接合部件4，踏杠1移动到缩回位置时，接合部件4可被锁定摆臂32和锁定座31夹持住，从而实现踏杠1的锁定。
在一些实施例中，接合部件4与踏杠1或踏杠支座22的连接方式不受限制，例如，接合部件4可拆卸地连接在踏杠1或踏杠支座22上，或者接合部件4与踏杠1或踏杠支座22一体形成。例如图13所示，接合部件4设在踏杠1上，且接合部件4与踏杠1一体形成。其中，当接合部件4与踏杠1可拆卸地连接时，接合部件4与踏杠1可以看作彼此不同的独立部件，当接合部件4与踏杠1一体形成时，接合部件4与踏杠1可以看作一个整体。
在一些具体地实施例中，如图13-16所示，接合部件4包括接合轴41，在缩回位置，锁定摆臂32和锁定座31将接合轴41夹持在它们之间以锁定踏杠1。
在一些实施例中，接合部件4还包括第一支撑耳42和第二支撑耳43，第一支撑耳42和第二支撑耳43彼此间隔开地设置，接合轴41的第一端与第一支撑耳42相连，接合轴41的第二端与第二支撑耳43相连，接合部件4设在踏杠1上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠1上，接合部件4设在踏杠支座22上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠支座22上。
在一些具体实施例中，如图13和图14所示，锁定座31具有第一卡槽313，在缩回位置，接合部件4被锁定在锁定摆臂32和第一卡槽313之间。
在一些具体实施例中，锁定摆臂32具有第二卡槽321，在缩回位置，接合部件4被锁定在第一卡槽313和第二卡槽321之间，以将踏杠1锁定在缩回位置。换言之，第一卡槽313和第二卡槽321构成锁定槽，接合部件4可以接合在该锁定槽内或从该锁定槽内脱离。
如图18所示，当锁定摆臂32转动到锁定位置，接合部件4被夹持在锁定摆臂32的第二卡槽321和锁定座31的第一卡槽313之间，通过接合部件4被锁定在第一卡槽313和第 二卡槽321之间，由此将踏杠1锁定在缩回位置。在一个具体示例中，接合部件4包括接合轴41，当锁定摆臂32转动到锁定位置，接合轴41被夹持在第二卡槽321和第一卡槽313之间，由此将踏杠1锁定在缩回位置。
在一些具体实施例中，锁定座31具有延伸臂部311，第一卡槽313设在延伸臂部311的自由端3111(如图14所示的延伸臂部311的下端)，锁定摆臂32具有枢接端322(图15所示的锁定摆臂32的上端)和自由端323(图15所示的锁定摆臂32的下端)，锁定摆臂32的枢接端与锁定座32可枢转地相连，第二卡槽321设在锁定摆臂32的自由端323。
在一些实施例中，如图13-14所示，第一卡槽313和第二卡槽321均为大体V形，但第一卡槽313和第二卡槽321的形状并不限于此，只要接合部件4能够可靠地夹在第一卡槽313和第二卡槽321之间即可。在一个具体示例中，接合部件4包括接合轴41，接合轴41的外周轮廓的一部分与第二卡槽321的内周轮廓相适配，接合轴41的外周轮廓的另一部分与第一卡槽313的内周轮廓相适配，从而可以更好地将接合轴41夹持在第一卡槽313和第二卡槽321之间。
在一些实施例中，接合轴41的横截面为非圆形，例如四边形、六边形等的多边形，其中图13、16-18示出了接合轴41的横截面积正六边形。可以理解的是，接合轴41的横截面并不限于此。
在一些实施例中，如图15-18所示，锁定部件3还包括驱动杆33和连接杆34。连接杆34的第一端341与锁定摆臂32可枢转地相连，连接杆34的第二端342与驱动杆33的第一端331可枢转地相连，驱动杆33的第二端332与锁定座31可枢转地相连。在该实施例中，驱动杆33的驱动连接杆34转动，连接杆34带动锁定摆臂32在锁定位置和最小释放位置之间摆动，和/或在最小释放位置和最大释放位置之间摆动。
在一些具体地实施例中，驱动杆33的第一端331设有U形凹槽335，连接杆34的第二端342配合在U形凹槽335内。具体地，驱动杆33包括第一凸耳333和第二凸耳334，第一凸耳333和第二凸耳334均从驱动杆33的本体上向外延伸，第一凸耳333和第二凸耳334相对设置且彼此间隔开以在它们之间形成U形凹槽335，连接杆34的第二端342伸入U形凹槽335内即夹持在第一凸耳333和第二凸耳334之间。
在一些具体地实施例中，锁定摆臂32的中部还设有贯通槽326，连接杆34的第一端341配合在贯通槽326内。
在一些具体地实施例中，锁定部件3还包括第一枢轴35、第二枢轴36、第三枢轴37和第四枢轴38，其中锁定摆臂32通过第一枢轴35与锁定座31可枢转地相连，驱动杆33通过第二枢轴36与锁定座31可枢转地相连，连接杆34通过第三枢轴37与驱动杆33可枢转地相连，连接杆34通过第四枢轴38与锁定摆臂32可枢转地相连。
进一步地，锁定摆臂32具有第一摆臂孔324和与贯通槽326连通的第二摆臂孔325，第一枢轴35可穿过第一摆臂孔324和锁定座31上的孔以将锁定摆臂32与锁定座31可枢转地相连；连接杆34的第一端341伸入贯通槽326内，第四枢轴38可穿过第二摆臂孔325和连接杆34上的孔以将锁定摆臂32与连接杆34可枢转地相连。
可以理解的是，接合部件4不仅限于接合轴41的形式，例如，如图9所示，接合部件4为接合凸起401，该接合凸起401可以被夹持在第一卡槽313和第二卡槽321之间，也可以从第一卡槽313和第二卡槽321之间释放。在一些实施例中，接合凸起401设在踏杠1上，也可以设在踏杠支座22上。在接合凸起401设在踏杠1上时，接合凸起401可以与踏杠1可拆卸地连接，也可以与踏杠1一体形成。在接合凸起401设在踏杠支座22上时，接合凸起401可以与踏杠支座22可拆卸地连接，也可以与踏杠支座22一体形成。
通过锁定摆臂32摆动，接合凸起401可以被夹持在第一卡槽313和第二卡槽321之间，也可以脱离第一卡槽313和第二卡槽321。优选地，接合凸起401的外周轮廓中的一部分与第一卡槽313的内周轮廓相适配，接合凸起401的外周轮廓中的另一部分与第二卡槽321的内周轮廓相适配。踏杠1移动到缩回位置时，锁定摆臂32摆动到锁定位置以将接合凸起401夹持在第一卡槽313和第二卡槽321之间，以将踏杠1锁定在缩回位置。当踏杠1需要从缩回位置朝向伸出位置移动时，锁定摆臂32摆动到释放位置，从将接合凸起401从第一卡槽313和第二卡槽321之间释放，以允许踏杠1离开缩回位置朝向伸出位置移动。
在一些实施例中，锁定座31安装在安装支座21上。换言之，锁定座31可以安装在安装支座21上，锁定座31可以看作与安装支座21为不同的部件。在另一些实施例中，锁定座31与安装支座21一体形成。换言之，锁定座31和安装支座21可以看作一个整体部件。
如图13-20所示，根据本发明另一些实施例的车用踏杠设备100包括踏杠1、臂组件23、锁定座31和锁定摆臂32。其中臂组件23用于驱动踏杠1在伸出位置和缩回位置之间移动。
锁定摆臂32在锁定位置和释放位置之间可摆动，其中在锁定位置，锁定摆臂32和锁定座31将踏杠1锁定在缩回位置；在释放位置，锁定摆臂32和锁定座31释放踏杠1以允许踏杠1从缩回位置朝向伸出位置移动。
在一些可选的实施例中，如图19-20所示，臂组件23由伸缩驱动电机61驱动以带动踏杠1在缩回位置和伸出位置之间移动；锁定摆臂32由摆动驱动电机62驱动在锁定位置与释放位置之间摆动。换言之，车用踏杠设备100由不同的电机控制臂组件23的伸缩运动和锁定摆臂32的摆动，臂组件23的伸缩运动由一个电机例如伸缩驱动电机61驱动，锁定摆臂32的摆动由另一个电机例如摆动驱动电机62驱动。
在一些具体地实施例中，伸缩驱动电机61和臂组件23相连，以在伸缩驱动电机61的 驱动下，通过臂组件23带动踏杠1在缩回位置和伸出位置之间移动。本领域技术人员可以理解的是，伸缩驱动电机61与臂组件23的第一臂231和第二臂232中的至少一个相连。换言之，伸缩驱动电机61可以仅与第一臂231相连，伸缩驱动电机61驱动第一臂231相对于安装支座21枢转，进而驱动踏杠支座22从而驱动踏杠1在伸出位置和缩回位置之间移动，伸缩驱动电机61也可以仅与第二臂232相连，伸缩驱动电机61驱动第二臂232相对于安装支座21枢转，进而驱动踏杠支座22从而驱动踏杠1在伸出位置和缩回位置之间移动，伸缩驱动电机61也可以同时与第一臂231和第二臂232相连，伸缩驱动电机61驱动第一臂231和第二臂232枢转，进而驱动踏杠支座22从而驱动踏杠1在伸出位置和缩回位置之间移动。
在一些具体地实施例中，摆动驱动电机62通过第二枢轴36和驱动杆33相连，摆动驱动电机62的驱动驱动杆33相对于锁定座31枢转，进而在连接杆34的带动下，驱动锁定摆臂32相对于锁定座32枢转，以使锁定摆臂32在锁定位置和释放位置之间摆动。
可以理解的是，驱动臂组件23的伸缩运动和锁定摆臂32摆动的方式并不局限于采用两个电机分别控制的形式，例如在另一些可选的实施例中，如图21-23所示，臂组件23和锁定摆臂32由单个驱动电机6驱动，单个驱动电机6与臂组件23相连，以驱动臂组件23带动踏杠1在伸出位置和缩回位置之间移动，且单个驱动电机6与锁定摆臂32相连以驱动锁定摆臂32在锁定位置和释放位置之间摆动。
具体地，驱动电机6既与锁定摆臂32相连，又与臂组件23相连，即臂组件23和锁定摆臂32由单个驱动电机6驱动，单个驱动电机6通过臂组件23驱动踏杠1在伸出位置和缩回位置之间移动，且单个驱动电机6通过驱动杆33和连接杆34驱动锁定摆臂32在锁定位置与释放位置之间摆动。在一些实施例中，车用踏杠设备100由同一个电机驱动伸缩装置2的伸缩运动和锁定摆臂32的摆动，提高了传动效率。
如图13-18所示，根据本发明另一些实施例的车辆1000包括车身200、踏杠支座22、踏杠1、臂组件23、接合轴41、锁定座31和锁定摆臂32。其中踏杠1安装在踏杠支座22上，臂组件23分别与车身200的底面201和踏杠支座22相连以驱动踏杠1在伸出位置和缩回位置之间移动。换言之，臂组件23的一端与车身200的底面201相连，臂组件23的另一端与踏杠支座22相连，以驱动踏杠1在伸出位置和缩回位置之间移动。
接合轴41设在踏杠1或踏杠支座22上。锁定座31具有第一卡槽313，锁定座31安装在车身200的底面201上。锁定摆臂32在锁定位置和释放位置之间可摆动，锁定摆臂32具有枢接端322和自由端323，其中锁定摆臂32的枢接端322可枢转地与锁定座31相连，锁定摆臂32的自由端323具有第二卡槽321，在锁定位置，接合轴41被夹持在第一卡槽313和第二卡槽321之间以将踏杠1锁定在缩回位置，在释放位置，接合轴41脱离第 一卡槽313和第二卡槽321以允许踏杠1从缩回位置朝向伸出位置移动。

在一些实施例中，第一支撑耳42和第二支撑耳43与踏杠1可拆卸式地相连或一体形成。换言之，第一支撑耳42与踏杠1相连且第一支撑耳42可拆卸，和第二支撑耳43与踏杠1相连且拆卸，或者，第一支撑耳42和第二支撑耳43与一体形成。
在一些实施例中，车用踏杠设备100还包括驱动杆33和连接杆34。连接杆34的第一端341与锁定摆臂32可枢转地相连，连接杆34的第二端342与驱动杆33的第一端331可枢转地相连，驱动杆33的第二端332与锁定座31可枢转地相连。在该实施例中，驱动杆33的驱动连接杆34转动，连接杆34带动锁定摆臂32在锁定位置和最小释放位置之间摆动，和/或在最小释放位置和最大释放位置之间摆动。

在一些实施例中，如图21-23所示，臂组件23和锁定摆臂32由单个驱动电机6驱动，单个驱动电机6与臂组件23相连，以驱动臂组件23带动踏杠1在伸出位置和缩回位置之间移动，且单个驱动电机6与锁定摆臂32相连以驱动锁定摆臂32在锁定位置和释放位置之间摆动。具体地，驱动电机6既与锁定摆臂32相连，又与臂组件23相连，即臂组件23和锁定摆臂32由单个驱动电机6驱动。
其中单个驱动电机6通过臂组件23驱动踏杠1在伸出位置和缩回位置之间移动，本领域技术人员可以理解的是，驱动电机6与臂组件23的第一臂231和第二臂232中的至少一个相连。换言之，驱动电机6可以仅与第一臂231相连，驱动电机6驱动第一臂231相对于安装支座21枢转，进而驱动踏杠支座22从而驱动踏杠1在伸出位置和缩回位置之间移动，驱动电机6也可以仅与第二臂232相连，驱动电机6驱动第二臂232相对于安装支座21枢转，进而驱动踏杠支座22从而驱动踏杠1在伸出位置和缩回位置之间移动，驱动电机6也可以同时与第一臂231和第二臂232相连，驱动电机6驱动第一臂231和第二臂232 枢转，进而驱动踏杠支座22从而驱动踏杠1在伸出位置和缩回位置之间移动。
而且单个驱动电机6通过驱动杆33和连接杆34驱动锁定摆臂32在锁定位置与释放位置之间摆动。在一些实施例中，车用踏杠设备100由同一个电机驱动伸缩装置2的伸缩运动和锁定摆臂32的摆动，提高了传动效率。
在一些实施例中，如图24-36说是，车用踏杠设备100还包括传动装置5，单个驱动电机6通过传动装置5可分别驱动驱动杆33和锁定摆臂32。传动装置5包括主动齿轮51、第一从动齿轮52和第二从动齿轮53，主动齿轮51具有有齿段511和无齿段512。

在一些可选的实施例中，如图24-31所示，主动齿轮51的有齿段511交替地与第一从动齿轮52和第二从动齿轮53啮合以交替地驱动第一从动齿轮52和第二从动齿轮53转动。换言之，主动齿轮51的有齿段511不同时与第一从动齿轮52和第二从动齿轮53啮合，只有在与一个从动齿轮脱离后才与另一个从动齿轮啮合。
在另一些可选的实施例中，如图24-26、32所示，主动齿轮51具有第一转动位置(如图24所示的主动齿轮51的位置和图32中所示的A位置)、第二转动位置(如图26所示的主动齿轮的位置和图32所示的B位置)以及位于第一转动位置和第二转动位置之间的第三转动位置(图32所示的C位置)，主动齿轮51在第一转动位置和第二转动位置之间可往复转动。
其中在第一转动位置，如图24所示，主动齿轮51的有齿段511与第二从动齿轮53啮合，且主动齿轮511的无齿段512与第一从动齿轮52相对；在第二转动位置，如图26所示，主动齿轮511的有齿段511与第一从动齿轮52啮合且主动齿轮511的无齿段512与第二从动齿轮53相对。
其中主动齿轮51从第一转动位置沿第一方向(图24和26所示的逆时针方向)转动到第三转动位置之前，主动齿轮51的有齿段511与第二从动齿轮53啮合且主动齿轮51的无齿段512与第一从动齿轮52相对，用以驱动锁紧摆臂32从锁定位置朝向释放位置移动。
其中主动齿轮51沿第一方向转动到第三转动位置时，主动齿轮51的有齿段511开始与第一从动齿轮52啮合，以开始驱动踏杠1从缩回位置朝向伸出位置移动。其中主动齿轮51从第三转动位置沿第一方向转动到第二转动位置的过程中，主动齿轮51的有齿段511 同时与第二从动齿轮53和第一从动齿轮52啮合，用于驱动锁紧摆臂32朝向释放位置移动的同时驱动踏杠1朝向伸出位置移动。
在再一些可选的实施例中，如图24-26、33所示，主动齿轮51具有第一转动位置(如图24所示的主动齿轮51的位置和图33中所示的A位置)、第二转动位置(如图26所示的主动齿轮的位置和图33所示的B位置)、位于第一转动位置和第二转动位置之间的第三转动位置(图33所示的C位置)以及位于第三转动位置和第二转动位置之间的第四转动位置(图33所示的D位置)，主动齿轮51在第一转动位置和第二转动位置之间可往复转动。
其中在第一转动位置，如图24所示，主动齿轮51的有齿段511与第二从动齿轮53啮合，且主动齿轮511的无齿段512与第一从动齿轮52相对；在第二转动位置，如图26所示，主动齿轮511的有齿段511与第一从动齿轮52啮合且主动齿轮511的无齿段512与第二从动齿轮53相对。
其中主动齿轮51从第一转动位置沿第一方向(图24和26所示的逆时针方向)转动到第三转动位置之前，主动齿轮51的有齿段511与第二从动齿轮53啮合且主动齿轮51的无齿段512与第一从动齿轮52相对，用以驱动锁定摆臂32从锁定位置朝向释放位置移动。
其中主动齿轮51沿第一方向转动到第三转动位置时，主动齿轮51的有齿段511开始与第一从动齿轮52啮合，以开始驱动踏杠1从缩回位置朝向伸出位置移动。其中主动齿轮51从第三转动位置沿第一方向转动到第四转动位置之前，主动齿轮51的有齿段511同时与第二从动齿轮53和第一从动齿轮52啮合，用于驱动锁紧摆臂32朝向释放位置移动的同时驱动踏杠1朝向伸出位置移动。
其中主动齿轮51沿第一方向转动到第四转动位置时，主动齿轮51的有齿段511开始与第二从动齿轮53脱离，锁紧摆臂32转动到释放位置。
其中主动齿轮51从第四转动位置沿第一方向转动到第二转动位置的过程中，主动齿轮51的有齿段511与第一从动齿轮52啮合且主动齿轮51的无齿段512与第二从动齿轮53相对，用以继续驱动踏杠1朝向伸出位置移动。
在一些具体地实施例中，如图34-36所示，车用踏杠设备100还包括主动凸轮54、从动凸轮55和止动摆杆56，主动凸轮54与主动齿轮51相连，主动凸轮54能够随着主动齿轮51一起转动。从动凸轮55与第一从动齿轮52相连，从动凸轮55能够随着第一从动齿轮52转动。止动摆杆56具有第一端561、第二端562和枢接部563，枢接部563位于止动摆杆56的第一端561和止动摆杆56的第二端562之间，止动摆杆56绕枢接部563可摆动。
其中主动齿轮51的有齿段511与第一从动齿轮52啮合时，主动凸轮54驱动止动摆杆56的第二端562与第二从动齿轮53接合以止挡第二从动齿轮53转动，且主动凸轮54释放从动凸轮55以允许第一从动齿轮52转动。
主动齿轮51的有齿段511与第二从动齿轮53啮合时，主动凸轮54驱动止动摆杆56的第二端562与第二从动齿轮53脱离以允许第二从动齿轮53转动，且主动凸轮54止挡从动凸轮55以止挡第一从动齿轮52转动。
进一步地，主动齿轮51与第一从动齿轮52啮合时，如图35-36所示，止动摆杆56的第一端561靠在主动凸轮54的远休止弧段542上以便止动摆杆56的第二端562与第二从动齿轮53接合以止挡第二从动齿轮53转动，且从动凸轮55的远休止弧段552与主动凸轮54的近休止弧段541相对。
换言之，主动齿轮51与第一从动齿轮52啮合时，主动齿轮51驱动第一从动齿轮52转动，且主动凸轮54随着主动齿轮51一起转动，主动凸轮54的近休止弧段541与从动凸轮55相对且彼此间隔开，即主动凸轮54不能约束从动凸轮55的运动，从动凸轮55能够随第一从动齿轮52一起转动。同时，主动凸轮54的远休止弧段542与止动摆杆56的第一端561相对，且止动摆杆56的第一端561抵靠在主动凸轮54的远休止弧段542上，由于止动摆杆56能够相对于枢接部563摆动，止动摆杆56的第二端562靠近第二从动齿轮53且止动摆杆56的第二端562能够接合在第二从动齿轮53上以止挡第二从动齿轮53转动。
主动齿轮51的有齿段511与第二从动齿轮53啮合时，如图34所示，从动凸轮55的远休止弧段552靠在主动凸轮54的远休止弧段542上，即主动凸轮54的远休止弧段542止挡住从动凸轮55的远休止弧段552，以止挡第一从动齿轮52转动，止动摆杆56的第一端561靠在主动凸轮54的近休止弧段541上以便止动摆杆56的第二端562与第二从动齿轮53脱离。
换言之，主动凸轮54具有近休止弧段541和远休止弧段542。从动凸轮55具有近休止弧段551和远休止弧段552。主动齿轮51与第二从动齿轮53啮合时，如图34所示，主动齿轮51驱动第二从动齿轮53转动，主动凸轮54随着主动齿轮51一起转动，主动凸轮54的远休止弧段542抵靠从动凸轮55以止挡从动凸轮55转动，从而止挡第一从动齿轮52转动。同时，主动凸轮54的近休止弧段541与止动摆杆56的第一端561相对，且止动摆杆56的第一端561抵靠在主动凸轮54的近休止弧段541上。由于止动摆杆56能够相对于枢接部563摆动，止动摆杆56的第二端562远离第二从动齿轮53以脱离第二从动齿轮53。
在一些实施例中，主动齿轮51与主动凸轮54一体形成，第一从动齿轮52与从动凸轮55一体形成。可以理解的是，主动齿轮51和主动凸轮54可以为彼此独立的两个部件，第一从动齿轮52与从动凸轮55可以为彼此独立的两个部件。
在一些具体地实施例中，传动装置5还包括主动齿轮轴57、第一从动齿轮轴35和第二从动齿轮轴36，其中主动齿轮轴57安装在锁定座31上且与驱动电机6相连，主动齿轮51安装在主动齿轮轴57上。
其中第一从动齿轮轴35为连接锁紧摆臂32和锁定座31的第一枢轴35，第一从动齿轮轴35的第一端与臂组件23相连，第一从动齿轮52安装在第一从动齿轮轴35的第二端，由此，第一从动齿轮轴35穿过锁定摆臂32和锁定座31与臂组件23的第一臂231和/或第二臂232相连，以在第一从动齿轮52的带动下驱动臂组件23伸展和收缩。
其中第二从动齿轮轴36为连接锁定座31和驱动杆33的第二枢轴36，第二从动齿轮轴36的第一端与驱动杆33相连，第二从动齿轮53安装在第二从动齿轮轴36的第二端，由此，第二从动齿轮53通过第二枢轴36与驱动杆33相连，以使第二从动齿轮53驱动驱动杆33转动以带动锁定摆臂32摆动。
可以理解的是，驱动臂组件23的伸缩运动和锁定摆臂32摆动的方式并不局限于采用单个驱动电机6驱动的形式，例如在另一些可选的实施例中，如图19-20所示，臂组件23由伸缩驱动电机61驱动，锁定摆臂32由摆动驱动电机62驱动，其中伸缩驱动电机61通过臂组件23驱动踏杠1在缩回位置和伸出位置之间移动，摆动驱动电机62通过驱动杆33和连接杆34驱动锁定摆臂32在锁定位置与释放位置之间摆动。
下面参考附图13-18和21-36描述根据本发明一些具体实施例的车用踏杠设备。
如图13-15和21-26所示，根据本发明实施例的车用踏杠设备100包括踏杠1、伸缩装置2、锁定座31、摆臂组件、传动装置5和单个驱动电机6，其中踏杠1在伸出位置和缩回位置之间可移动。
如图13-15所示，伸缩装置2包括安装支座21、踏杠支座22和臂组件23。踏杠1安装在踏杠支座22上，臂组件23分别与安装支座21和踏杠支座22可枢转地相连以驱动踏杠1在伸出位置和缩回位置之间移动。换言之，臂组件23的一端与安装支座21可枢转地相连，臂组件23的另一端与踏杠支座22可枢转地相连，臂组件23在驱动装置例如电机的驱动下带动踏杠1在伸出位置和缩回位置之间移动。具体地，安装支座21可以安装在车身200的底面201。
摆臂组件包括锁定摆臂32、连接杆34和驱动杆33，连接杆34的第一端341与锁定摆臂32可枢转地相连，连接杆34的第二端342与驱动杆33的第一端331可枢转地相连，驱动杆33的第二端332与锁定座31可枢转地相连，驱动杆33通过连接杆34驱动锁定摆臂32在锁定位置和释放位置之间摆动。其中在锁定位置，锁定摆臂32和锁定座31将踏杠1锁定在缩回位置；在释放位置，锁定摆臂32和锁定座31释放踏杠1，以便踏杠1能够从缩回位置朝向伸出位置移动。
如图24-26所示，传动装置5包括主动齿轮51、第一从动齿轮52和第二从动齿轮53，第一从动齿轮52可由主动齿轮51驱动且与臂组件23相连，以驱动臂组件23带动踏杠1在伸出位置和缩回位置之间移动，第二从动齿轮53可由主动齿轮51驱动且与驱动杆33相 连，以通过驱动杆33驱动锁定摆臂32在锁定位置和释放位置之间摆动。
如图21-23所示，驱动电机6与主动齿轮51相连，以通过主动齿轮51和第一从动齿轮52驱动臂组件23，且通过主动齿轮51和第二从动齿轮53驱动驱动杆33。换言之，驱动电机6通过传动装置5既可驱动臂组件23以使踏杠1在伸出位置和缩回位置之间移动，也可驱动驱动杆33以使锁定摆臂32在锁定位置和释放位置之间摆动。
在一些实施例中，在踏杠1离开缩回位置朝向伸出位置移动之前，锁定摆臂32从锁定位置转动到释放位置。换言之，当踏杠1需要从缩回位置朝向伸出位置移动之前，锁定摆臂32先从锁定位置转动到释放位置，以释放接合部件4，从而臂组件23带动踏杠1从图18所示的缩回位置移动到图16所示的伸出位置。
在一些实施例中，释放位置包括最大释放位置和最小释放位置，最小释放位置位于锁定位置与最大释放位置之间。具体地，如图18所示，踏杠1在缩回位置，锁定摆臂32在锁定位置，锁定摆臂32和锁定座31将接合部件4夹持在锁定摆臂32和锁定座31之间以锁定踏杠1。如图17所示，锁定摆臂32从锁定位置向右转动到最小释放位置，接合部件4脱离锁定摆臂32和锁定座31的夹持，即接合部件4被释放，且踏杠1移动到伸出位置和缩回位置之间的中间位置。随后，如图16所示，锁定摆臂32从最小释放位置向右继续转动到达最大释放位置，且踏杠1从中间位置移动到伸出位置。
其中对于锁定摆臂32的转动和臂组件23的伸缩运动之间的相互关系为：
在一些实施例中，在踏杠1离开缩回位置朝向伸出位置移动之前，锁定摆臂32从锁定位置转动到最小释放位置，且在锁定摆臂从最小释放位置转动到最大释放位置的同时，踏杠1从缩回位置移动到伸出位置。
在一些实施例中，踏杠1还具有位于缩回位置与伸出位置之间的中间位置，在踏杠1离开缩回位置朝向伸出位置移动之前，锁定摆臂32从锁定位置转动到最小释放位置，其中在锁定摆臂32从最小释放位置转动到最大释放位置的同时，踏杠1从缩回位置移动到中间位置，其中在踏杠1从中间位置移动到伸出位置的过程中，锁定摆臂32在最大释放位置静止不动。
可以理解的是，除了锁定摆臂32和踏杠1的运动之外，还可以是，首先锁定摆臂32从锁定位置转动到最小释放位置。
其次踏杠1从缩回位置移动到中间位置，即锁定摆臂32转动到最小释放位置后停留一段时间，且在该段时间内，踏杠1从缩回位置移动到中间位置，在该段时间结束的时刻，踏杠1处于伸出位置与缩回位置之间的中间位置，且锁定摆臂32处于最大释放位置与锁定位置之间的最小释放位置，例如图17所示。
再次，踏杠1从中间位置移动到伸出位置，锁定摆臂32从最小释放位置转动到最大释 放位置，该过程中踏杠1的移动和锁定摆臂32的转动可以同时进行，也可以踏杠1先移动，锁定摆臂32再转动，还可以锁定摆臂32先转动，踏杠1再移动。
如图13-15、21-26所示，根据本发明另一些实施例的车用踏杠设备100包括踏杠1、臂组件23、锁定座31、锁定摆臂32、连接杆34、驱动杆33、传动装置5和单个驱动电机6。其中臂组件23用于驱动踏杠1在伸出位置和缩回位置之间移动。
锁定摆臂32在锁定位置和释放位置之间可摆动，其中在锁定位置，锁定摆臂32和锁定座31将踏杠1锁定在缩回位置；在释放位置，锁定摆臂32和锁定座31释放踏杠1以允许踏杠1从缩回位置朝向伸出位置移动。
连接杆34的第一端341与锁定摆臂32可枢转地相连，驱动杆33的第一端331与连接杆34的第二端342可枢转地相连，驱动杆33的第二端332与锁定座31可枢转地相连，驱动杆33通过连接杆34驱动锁定摆臂32摆动。
如图24-26所示，传动装置5包括主动齿轮51、第一从动齿轮52和第二从动齿轮53，第一从动齿轮52可由主动齿轮51驱动且与臂组件23相连，以驱动臂组件23带动踏杠1在伸出位置和缩回位置之间移动，第二从动齿轮53可由主动齿轮51驱动且与驱动杆33相连，以通过驱动杆33驱动锁定摆臂32在锁定位置和释放位置之间摆动。
如图21-23所示，驱动电机6与主动齿轮51相连，以通过主动齿轮51和第一从动齿轮52驱动臂组件23，且通过主动齿轮51和第二从动齿轮53驱动驱动杆33。换言之，驱动电机6通过传动装置5既可驱动臂组件23以使踏杠1在伸出位置和缩回位置之间移动，也可驱动驱动杆33以使锁定摆臂32在锁定位置和释放位置之间摆动。
在一些具体的实施例中，如图23所示，传动装置5还包括主动齿轮轴57、第一从动齿轮轴35和第二从动齿轮轴36，其中主动齿轮轴57安装在锁定座31上且与驱动电机6相连，主动齿轮51安装在主动齿轮轴57上。
其中第一从动齿轮轴35为连接锁紧摆臂32和锁定座31的第一枢轴35，第一从动齿轮轴35的第一端与臂组件23相连，第一从动齿轮52安装在第一从动齿轮轴35的第二端，由此，第一从动齿轮轴35穿过锁定摆臂32和锁定座31与臂组件23的第一臂231和/或第二臂232相连，以在第一从动齿轮52的带动下驱动臂组件23伸展和收缩。
其中第二从动齿轮轴36为连接锁定座31和驱动杆33的第二枢轴36，第二从动齿轮轴36的第一端与驱动杆33相连，第二从动齿轮53安装在第二从动齿轮轴36的第二端，由此，第二从动齿轮53通过第二枢轴36与驱动杆33相连，以使第二从动齿轮53驱动驱动杆33转动以带动锁定摆臂32摆动。
在一些可选的实施例中，如图24-31所示，主动齿轮5包括有齿段511和无齿段512，主动齿轮51的有齿段511交替地与第一从动齿轮52和第二从动齿轮53啮合以交替地驱动 第一从动齿轮52和第二从动齿轮53转动。换言之，主动齿轮51的有齿段511不同时与第一从动齿轮52和第二从动齿轮53啮合，只有在与一个从动齿轮脱离后才与另一个从动齿轮啮合。
踏杠1在缩回位置时，如图24所示，第二从动齿轮53与主动齿轮51的有齿段511啮合，第一从动齿轮52与主动齿轮51的无齿段512相对；踏杠1在伸出位置，如图26所示，第一从动齿轮52与主动齿轮51的有齿段511啮合，且第二从动齿轮53与主动齿轮51的无齿段512相对。
换言之，通过具有无齿段512和有齿段511的主动齿轮51，能够驱动第一从动齿轮52和第二从动齿轮53。在踏杠1处于缩回位置时，主动齿轮51的有齿段511啮合第二从动齿轮53，由此通过第二从动齿轮53驱动锁定摆臂32摆动以将踏杠1锁定在缩回位置，以及驱动锁定摆臂32摆动以释放踏杠1，且主动齿轮51的无齿段512与第一从动齿轮52相对，由此主动齿轮51不驱动第一从动齿轮52转动。在踏杠1处于伸出位置时，主动齿轮51的有齿段511啮合第一从动齿轮52，以通过第一从动齿轮52驱动臂组件23伸缩以驱动踏杠1移动，且主动齿轮51的无齿段512与第二从动齿轮53相对，从而主动齿轮51不驱动第二从动齿轮53转动。
在一些具体地实施例中，主动齿轮51具有第一转动位置(如图24所示的主动齿轮51的位置和图30-31中所示的A位置)和第二转动位置(如图26所示的主动齿轮的位置和图30-31所示的B位置)，主动齿轮51在第一转动位置和第二转动位置之间可往复转动。其中在第一转动位置，如图24所示，主动齿轮51的有齿段511与第二从动齿轮53啮合，且主动齿轮511的无齿段512与第一从动齿轮52相对；在第二转动位置，如图26所示，主动齿轮511的有齿段511与第一从动齿轮52啮合且主动齿轮511的无齿段512与第二从动齿轮53相对。
其中在图24-26和图30所示的具体实施例中，主动齿轮51还包括具有位于第一转动位置和第二转动位置之间的第三转动位置(如图25所示的位置和图30中所示的C位置)，如图24-26和图30所示，主动齿轮51从第一转动位置沿第一方向(如图24-26所示的逆时针方向)转动到第三转动位置之前，如图24、30所示，主动齿轮51的有齿段511与第二从动齿轮53啮合，且主动齿轮51的无齿段512与第一从动齿轮52相对，以使主动齿轮51驱动锁定摆臂32从锁定位置朝向释放位置转动。
其中主动齿轮51沿第一方向转动到第三转动位置时，如图25、30所示，主动齿轮51的有齿段511开始与第二从动齿轮53脱离且开始与第一从动齿轮52啮合，其中锁定摆臂32转动到释放位置，且主动齿轮51开始驱动踏杠1从缩回位置朝向伸出位置移动。
其中主动齿轮51从第三转动位置沿第一方向转动到第二转动位置的过程中，如图26、 30所示，主动齿轮51的有齿段511与第一从动齿轮52啮合且主动齿轮51的无齿段512与第二从动齿轮53相对，以使主动齿轮51驱动踏杠1从缩回位置朝向伸出位置移动。
具体地，图30(A)-30(C)示出了主动齿轮51沿第一方向从第一转动位置转动到第二转动位置的过程中锁定摆臂32和第二臂232的关系示意图。其中如图30(A)所示，第二臂232和锁定摆臂32均处于竖直状态，且第二臂232在缩回位置且锁定摆臂32在锁定位置，首先主动齿轮51的有齿段511与第二从动齿轮53啮合，用于驱动锁定摆臂32向右转动，直至锁定摆臂32向右转动α角度，即锁定摆臂32转动到释放位置，如图30(B)所示，其中主动齿轮51的有齿段511与第二从动齿轮53脱离开且开始与第一从动齿轮52啮合，用以在锁定摆臂32在释放位置时主动齿轮51开始驱动第二臂232向左转动，以使第二臂232开始从缩回位置朝向伸出位置移动，且锁定摆臂32静止不动。直至第二臂232向左转动β角度，如图30(C)所示，第二臂232移动到伸出位置。
进一步地，如图27-29所示，主动齿轮51从第二转动位置沿与第一方向相反的第二方向(如图27-29所示的顺时针方向)转动到第三转动位置之前，如图27所示，主动齿轮51的有齿段511与第一从动齿轮52啮合，主动齿轮51的无齿段512与第二从动齿轮53相对，以使主动齿轮51驱动踏杠1从伸出位置朝向缩回位置移动。
其中主动齿轮51沿第二方向转动到第三转动位置时，如图28所示，主动齿轮51的有齿段511开始与第一从动齿轮52脱离且开始与第二从动齿轮53啮合，其中踏杠1移动到缩回位置，且主动齿轮51开始驱动锁定摆臂32从释放位置朝向锁定位置移动。
其中主动齿轮51从第三转动位置沿第二方向转动到第一转动位置的过程中，如图29所示，主动齿轮51的有齿段511与第二从动齿轮53啮合且主动齿轮51的无齿段512与第一从动齿轮52相对，以使主动齿轮51驱动锁定摆臂32从释放位置朝向锁定位置移动。
具体地，图30(D)-30(F)示出了主动齿轮51沿第二方向从第二转动位置转动到第一转动位置的过程中锁定摆臂32和第二臂232的关系示意图。其中，如图30(D)所示，第二臂232在伸出位置且锁定摆臂32在锁定位置，首先主动齿轮51的有齿段511与第一从动齿轮52啮合，用于驱动第二臂232向右转动，以使其从伸出位置朝向缩回位置移动，直至第二臂232向右转动β角度，即回复到原始竖直状态，如图30(E)所示，第二臂232移动到缩回位置，随后主动齿轮51的有齿段511与第一从动齿轮52脱离开且开始与第二从动齿轮53啮合，用以在第二臂232停留在缩回位置时主动齿轮51驱动锁定摆臂32向左转动，即驱动锁定摆臂32从释放位置向锁定位置转动，直至锁定摆臂32向左转动α角度，如图30(F)所示，锁定摆臂32转动到锁定位置。

可以理解的是，在图32和图33所示的实施例中，主动齿轮51的有齿段511与第一从动齿轮52和第二从动齿轮53的啮合有重叠部分，即存在一定的时间且在该时间内，主动齿轮51的有齿段511既与第一从动齿轮52啮合，也与第二从动齿轮53。
在一些实施例中，如图34-36所示，车用踏杠设备100还包括主动凸轮54、从动凸轮55和止动摆杆56，主动凸轮54与主动齿轮51相连，主动凸轮54能够随着主动齿轮51一起转动。从动凸轮55与第一从动齿轮52相连，从动凸轮55能够随着第一从动齿轮52转动。止动摆杆56具有第一端561、第二端562和枢接部563，枢接部563位于止动摆杆56的第一端561和止动摆杆56的第二端562之间，止动摆杆56绕枢接部563可摆动。
其中主动齿轮51的有齿段511与第一从动齿轮52啮合时，主动凸轮54驱动止动摆杆56的第二端562与第二从动齿轮53接合以止挡第二从动齿轮53转动，且主动凸轮54释放从动凸轮55以允许第一从动齿轮52转动。
主动齿轮51的有齿段511与第二从动齿轮53啮合时，主动凸轮54驱动止动摆杆56的第二端562与第二从动齿轮53脱离以允许第二从动齿轮53转动，且主动凸轮54止挡从 动凸轮55以止挡第一从动齿轮52转动。
进一步地，主动齿轮51与第一从动齿轮52啮合时，如图35-36所示，止动摆杆56的第一端561靠在主动凸轮54的远休止弧段542上以便止动摆杆56的第二端562与第二从动齿轮53接合以止挡第二从动齿轮53转动，且从动凸轮55的远休止弧段552与主动凸轮54的近休止弧段541相对。
换言之，主动齿轮51与第一从动齿轮52啮合时，主动齿轮51驱动第一从动齿轮52转动，且主动凸轮54随着主动齿轮51一起转动，主动凸轮54的近休止弧段541与从动凸轮55相对且彼此间隔开，即主动凸轮54不能约束从动凸轮55的运动，从动凸轮55能够随第一从动齿轮52一起转动。同时，主动凸轮54的远休止弧段542与止动摆杆56的第一端561相对，且止动摆杆56的第一端561抵靠在主动凸轮54的远休止弧段542上，由于止动摆杆56能够相对于枢接部563摆动，止动摆杆56的第二端562靠近第二从动齿轮53且止动摆杆56的第二端562能够接合在第二从动齿轮53上以止挡第二从动齿轮53转动。
主动齿轮51的有齿段511与第二从动齿轮53啮合时，如图34所示，从动凸轮55的远休止弧段552靠在主动凸轮54的远休止弧段542上，即主动凸轮54的远休止弧段542止挡住从动凸轮55的远休止弧段552，以止挡第一从动齿轮52转动，止动摆杆56的第一端561靠在主动凸轮54的近休止弧段541上以便止动摆杆56的第二端562与第二从动齿轮53脱离。
换言之，主动凸轮54具有近休止弧段541和远休止弧段542。从动凸轮55具有近休止弧段551和远休止弧段552。主动齿轮51与第二从动齿轮53啮合时，如图34所示，主动齿轮51驱动第二从动齿轮53转动，主动凸轮54随着主动齿轮51一起转动，主动凸轮54的远休止弧段542抵靠从动凸轮55以止挡从动凸轮55转动，从而止挡第一从动齿轮52转动。同时，主动凸轮54的近休止弧段541与止动摆杆56的第一端561相对，且止动摆杆56的第一端561抵靠在主动凸轮54的近休止弧段541上。由于止动摆杆56能够相对于枢接部563摆动，止动摆杆56的第二端562远离第二从动齿轮53以脱离第二从动齿轮53。

换言之，第一止动部件501和第二止动部件56能够实现第一从动齿轮52和第二从动齿轮53的转动不同时进行，主动齿轮51驱动第一从动齿轮52转动时，第二止动部件56能够止挡第二从动齿轮53转动，以避免由于惯性等因素引起的第二从动齿轮53的转动。主动齿轮51驱动第二从动齿轮53转动时，第一止动部件501能够止挡第一从动齿轮52转动，以避免由于惯性等因素引起的第一从动齿轮52的转动。

具体地，主动齿轮51与第一从动齿轮52啮合时，如图35-36所示，止动摆杆56的第一端561靠在主动凸轮54的远休止弧段542上以便止动摆杆56的第二端562与第二从动齿轮53接合以止挡第二从动齿轮53转动，且从动凸轮55的远休止弧段552与主动凸轮54的近休止弧段541相对。
换言之，主动齿轮51与第一从动齿轮52啮合时，主动齿轮51驱动第一从动齿轮52转动，且主动凸轮54随着主动齿轮51一起转动，主动凸轮54的近休止弧段541与从动凸轮55相对且彼此间隔开，即主动凸轮54不能约束从动凸轮55的运动，从动凸轮55能够随第一从动齿轮52一起转动。同时，主动凸轮54的远休止弧段542与止动摆杆56的第一端561相对，且止动摆杆56的第一端561抵靠在主动凸轮54的远休止弧段542上，由于止动摆杆56能够相对于枢接部563摆动，止动摆杆56的第二端562靠近第二从动齿轮53且止动摆杆56的第二端562能够接合在第二从动齿轮53上以止挡第二从动齿轮53转动。
可以理解的是，止动摆杆56作为第二止动部件56，能够在主动齿轮51的有齿段511与第一从动齿轮52啮合时止挡第二从动齿轮53转动，且在主动齿轮51的有齿段511与第一从动齿轮52脱离时释放第二从动齿轮53，以便后续在主动齿轮51的有齿段511与第二从动齿轮53啮合时，主动齿轮51能够带动第二从动齿轮53转动。

换言之，主动凸轮54具有近休止弧段541和远休止弧段542。从动凸轮55具有近休止弧段551和远休止弧段552。主动齿轮51与第二从动齿轮53啮合时，如图34所示，主动齿轮51驱动第二从动齿轮53转动，主动凸轮54随着主动齿轮51一起转动，主动凸轮54的远休止弧段542抵靠从动凸轮55以止挡从动凸轮55转动，从而止挡第一从动齿轮52转动。同时，主动凸轮54的近休止弧段541与止动摆杆56的第一端561相对，且止动摆杆56的第一端561抵靠在主动凸轮54的近休止弧段541上。由于止动摆杆56能够相对于枢接部563摆动，止动摆杆56的第二端562远离第二从动齿轮53以脱离第二从动齿轮53。
可以理解的是，主动凸轮54和从动凸轮55作为第一止动部件501，能够在主动齿轮51的有齿段511与第二从动齿轮53啮合时止挡第一从动齿轮52转动，而且在主动齿轮51的有齿段511与第二从动齿轮53脱离时释放第一从动齿轮52，以便后续在主动齿轮51的有齿段511与第一从动齿轮52啮合时，主动齿轮51能够带动第一从动齿轮52转动。
主动齿轮51从第一转动位置朝向第二转动位置转动时，如图34所示，主动齿轮51的有齿段511首先驱动第二从动齿轮53转动，主动凸轮54的远休止弧段542抵靠从动凸轮54的远休止弧段542以止挡第一从动齿轮52转动，且止动摆杆56的第一端561抵靠在主动凸轮54的近休止弧段541上以使止动摆杆56的第二端562脱离第二从动齿轮53。然后，如图35所示，主动齿轮51转动使得主动齿轮51的有齿段511与第二从动齿轮53脱离，并与第一从动齿轮52啮合，且主动凸轮54随主动齿轮51转动使得主动凸轮54的近休止弧段541与从动凸轮54彼此相对且间隔开，主动凸轮54的近休止弧段541对从动凸轮54不构成约束，止动摆杆56的第一端抵靠在主动凸轮54的远休止弧段542上以使止动摆杆56的第二端562接合在第二从动齿轮53上以止挡第二从动齿轮53转动。
在一些实施例中，主动齿轮51与主动凸轮54同轴设置，第一从动齿轮52与从动凸轮55同轴设置。
在一些实施例中，主动齿轮51与主动凸轮54一体形成，第一从动齿轮52与从动凸轮55一体形成。可以理解的是，主动齿轮51和主动凸轮54可以为彼此独立的两个部件，第一从动齿轮52与从动凸轮55可以为彼此独立的两个部件。

换言之，主动齿轮51与第一从动齿轮52啮合时，主动齿轮51驱动第一从动齿轮52转动，且主动凸轮54随着主动齿轮51一起转动，主动凸轮54的近休止弧段541与从动凸轮55相对且彼此间隔开，即主动凸轮54不能约束从动凸轮55的运动，从动凸轮55能够随第一从动齿轮52一起转动。同时，主动凸轮54的远休止弧段542与止动摆杆56的第一端561相对，且止动摆杆56的第一端561抵靠在主动凸轮54的远休止弧段542上，由于 止动摆杆56能够相对于枢接部563摆动，止动摆杆56的第二端562靠近第二从动齿轮53且止动摆杆56的第二端562能够接合在第二从动齿轮53上以止挡第二从动齿轮53转动。
可以理解的是，止动摆杆56作为第二止动部件56，能够在主动齿轮51的有齿段511与第一从动齿轮52啮合时止挡第二从动齿轮53转动，且在主动齿轮51的有齿段511与第一从动齿轮52脱离时释放第二从动齿轮53，以便后续在主动齿轮51的有齿段511与第二从动齿轮53啮合时，主动齿轮51能够带动第二从动齿轮53转动。
主动齿轮51的有齿段511与第二从动齿轮53啮合时，如图34所示，从动凸轮55的远休止弧段552靠在主动凸轮54的远休止弧段542上，即主动凸轮54的远休止弧段542止挡住从动凸轮55的远休止弧段552，以止挡第一从动齿轮52转动，止动摆杆56的第一端561靠在主动凸轮54的近休止弧段541上以便止动摆杆56的第二端562与第二从动齿轮53脱离。
换言之，主动凸轮54具有近休止弧段541和远休止弧段542。从动凸轮55具有近休止弧段551和远休止弧段552。主动齿轮51与第二从动齿轮53啮合时，如图34所示，主动齿轮51驱动第二从动齿轮53转动，主动凸轮54随着主动齿轮51一起转动，主动凸轮54的远休止弧段542抵靠从动凸轮55以止挡从动凸轮55转动，从而止挡第一从动齿轮52转动。同时，主动凸轮54的近休止弧段541与止动摆杆56的第一端561相对，且止动摆杆56的第一端561抵靠在主动凸轮54的近休止弧段541上。由于止动摆杆56能够相对于枢接部563摆动，止动摆杆56的第二端562远离第二从动齿轮53以脱离第二从动齿轮53。
可以理解的是，主动凸轮54和从动凸轮55作为第一止动部件501，能够在主动齿轮51的有齿段511与第二从动齿轮53啮合时止挡第一从动齿轮52转动，而且在主动齿轮51的有齿段511与第二从动齿轮53脱离时释放第一从动齿轮52，以便后续在主动齿轮51的有齿段511与第一从动齿轮52啮合时，主动齿轮51能够带动第一从动齿轮52转动。
主动齿轮51从第一转动位置朝向第二转动位置转动时，如图34所示，主动齿轮51的有齿段511首先驱动第二从动齿轮53转动，主动凸轮54的远休止弧段542抵靠从动凸轮54的远休止弧段542以止挡第一从动齿轮52转动，且止动摆杆56的第一端561抵靠在主动凸轮54的近休止弧段541上以使止动摆杆56的第二端562脱离第二从动齿轮53。然后，如图35所示，主动齿轮51转动使得主动齿轮51的有齿段511与第二从动齿轮53脱离，并与第一从动齿轮52啮合，且主动凸轮54随主动齿轮51转动使得主动凸轮54的近休止弧段541与从动凸轮54彼此相对且间隔开，主动凸轮54的近休止弧段541对从动凸轮54不构成约束，止动摆杆56的第一端抵靠在主动凸轮54的远休止弧段542上以使止动摆杆56的第二端562接合在第二从动齿轮53上以止挡第二从动齿轮53转动。
在一些实施例中，主动齿轮51与主动凸轮54同轴设置，第一从动齿轮52与从动凸轮 55同轴设置。
在一些实施例中，主动齿轮51与主动凸轮54一体形成，第一从动齿轮52与从动凸轮55一体形成。可以理解的是，主动齿轮51和主动凸轮54可以为彼此独立的两个部件，第一从动齿轮52与从动凸轮55可以为彼此独立的两个部件。
下面参考附图1-3和13-20描述根据本发明另一些实施例的车用踏杠设备和车辆。
如图1-3和13所示，根据本发明实施例的车辆1000包括车身200、踏杠1、伸缩装置2、锁定座31和锁定摆臂32。
伸缩装置2包括踏杠支座22和臂组件23，踏杠1安装在踏杠支座22上，臂组件23分别与车身200和踏杠支座22可枢转地相连以驱动踏杠1在伸出位置和缩回位置之间移动。换言之，臂组件23的一端与车身200的底面201可枢转地相连，臂组件23的另一端与踏杠支座22可枢转地相连，臂组件23在驱动装置例如电机的驱动下带动踏杠1在伸出位置和缩回位置之间移动。
可以理解的是，在该实施例中，车用踏杠设备100不包括安装支座21，臂组件23的一端直接可枢转地连接在车身200的底面201。
锁定摆臂32在锁定位置和释放位置之间可摆动，其中在锁定位置，锁定摆臂32和锁定座31将踏杠1锁定在缩回位置，在释放位置，锁定摆臂32和锁定座31释放踏杠1，以便踏杠1能够从缩回位置朝向伸出位置移动。
在一些实施例中，在踏杠1离开缩回位置朝向伸出位置移动之前，锁定摆臂32从锁定位置转动到释放位置。换言之，当踏杠1需要从缩回位置朝向伸出位置移动之前，锁定摆臂32先从锁定位置转动到释放位置，以释放接合部件4，从而臂组件23带动踏杠1从图18所示的缩回位置移动到图16所示的伸出位置。
在一些实施例中，释放位置包括最大释放位置和最小释放位置，最小释放位置位于锁定位置与最大释放位置之间。具体地，如图18所示，踏杠1在缩回位置，锁定摆臂32在锁定位置，锁定摆臂32和锁定座31将接合部件4夹持在锁定摆臂32和锁定座31之间以锁定踏杠1。如图17所示，锁定摆臂32从锁定位置向右转动到最小释放位置，接合部件4脱离锁定摆臂32和锁定座31的夹持，即接合部件4被释放，且踏杠1移动到伸出位置和缩回位置之间的中间位置。随后，如图16所示，锁定摆臂32从最小释放位置向右继续转动到达最大释放位置，且踏杠1从中间位置移动到伸出位置。
锁定摆臂32的转动和臂组件23的伸缩运动之间的相互关系为：
在一些实施例中，在踏杠1离开缩回位置朝向伸出位置移动之前，锁定摆臂32从锁定位置转动到最小释放位置，且在锁定摆臂从最小释放位置转动到最大释放位置的同时，踏杠1从缩回位置移动到伸出位置。
在一些实施例中，踏杠1还具有位于缩回位置与伸出位置之间的中间位置，在踏杠1离开缩回位置朝向伸出位置移动之前，锁定摆臂32从锁定位置转动到最小释放位置，其中在锁定摆臂32从最小释放位置转动到最大释放位置的同时，踏杠1从缩回位置移动到中间位置，其中在踏杠1从中间位置移动到伸出位置的过程中，锁定摆臂32在最大释放位置静止不动。
可以理解的是，除了锁定摆臂32和踏杠1的运动之外，还可以是，首先锁定摆臂32从锁定位置转动到最小释放位置。
其次踏杠1从缩回位置移动到中间位置，即锁定摆臂32转动到最小释放位置后停留一段时间，且在该段时间内，踏杠1从缩回位置移动到中间位置，在该段时间结束的时刻，踏杠1处于伸出位置与缩回位置之间的中间位置，且锁定摆臂32处于最大释放位置与锁定位置之间的最小释放位置，例如图17所示。
再次，踏杠1从中间位置移动到伸出位置，锁定摆臂32从最小释放位置转动到最大释放位置，该过程中踏杠1的移动和锁定摆臂32的转动可以同时进行，也可以踏杠1先移动，锁定摆臂32再转动，还可以锁定摆臂32先转动，踏杠1再移动。
在一些实施例中，踏杠1在缩回位置贴靠在车身200的侧面的下沿处，例如踏杠1沿竖直方向定向且贴靠在车身200的侧面的下沿处，由此踏杠1盖住车身200的下沿。在另一些实施例中，踏杠1倾斜地贴靠在车身的底面201与车身200的侧面的交界处，换言之，踏杠1相对于车身200的侧面倾斜设置，且贴靠在车身的底面201和车身200的侧面的交界处，由此踏杠1可以盖住车身的底面201的外沿和车身200的侧面的下沿。由此，通过锁定部件3在缩回位置锁定踏杠1，踏杠1可以用作车辆的保险杠而起到防护功能，以保护车身以防止车辆1被撞击或刮蹭。
在一些实施例中，踏杠1和踏杠支座22中的一个具有接合部件4，在缩回位置，锁定摆臂32和锁定座32将接合部件4夹持它们之间以锁定踏杠1。换言之，踏杠1具有接合部件4，或者踏杠支座22具有接合部件4，踏杠1移动到缩回位置时，接合部件4可被锁定摆臂32和锁定座31夹持住，从而实现踏杠1的锁定。
在一些实施例中，接合部件4与踏杠1或踏杠支座22的连接方式不受限制，例如，接合部件4可拆卸地连接在踏杠1或踏杠支座22上，或者接合部件4与踏杠1或踏杠支座22一体形成。例如图13所示，接合部件4设在踏杠1上，且接合部件4与踏杠1一体形成。其中，当接合部件4与踏杠1可拆卸地连接时，接合部件4与踏杠1可以看作彼此不同的独立部件，当接合部件4与踏杠1一体形成时，接合部件4与踏杠1可以看作一个整体。
在一些具体地实施例中，如图13-16所示，接合部件4包括接合轴41，在缩回位置， 锁定摆臂32和锁定座31将接合轴41夹持在它们之间以锁定踏杠1。
在一些实施例中，接合部件4还包括第一支撑耳42和第二支撑耳43，第一支撑耳42和第二支撑耳43彼此间隔开地设置，接合轴41的第一端与第一支撑耳42相连，接合轴41的第二端与第二支撑耳43相连，接合部件4设在踏杠1上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠1上，接合部件4设在踏杠支座22上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠支座22上。
在一些具体实施例中，如图13和图14所示，锁定座31具有第一卡槽313，锁定摆臂32具有第二卡槽321，在缩回位置，接合轴41被锁定在第一卡槽313和第二卡槽321之间，以将踏杠1锁定在缩回位置。换言之，第一卡槽313和第二卡槽321构成锁定槽，接合部件4可以接合在该锁定槽内或从该锁定槽内脱离。
如图18所示，当锁定摆臂32转动到锁定位置，接合部件4被夹持在锁定摆臂32的第二卡槽321和锁定座31的第一卡槽313之间，通过接合部件4被锁定在第一卡槽313和第二卡槽321之间，由此将踏杠1锁定在缩回位置。在一个具体示例中，接合部件4包括接合轴41，当锁定摆臂32转动到锁定位置，接合轴41被夹持在第二卡槽321和第一卡槽313之间，由此将踏杠1锁定在缩回位置。
在一些具体实施例中，锁定座31具有延伸臂部311，第一卡槽313设在延伸臂部311的自由端3111(如图14所示的延伸臂部311的下端)，锁定摆臂32具有枢接端322(图15所示的锁定摆臂32的上端)和自由端323(图15所示的锁定摆臂32的下端)，锁定摆臂32的枢接端322与锁定座32可枢转地相连，第二卡槽321设在锁定摆臂32的自由端323。
如图1-3、13-20所示，根据本发明另一些实施例的车辆1000包括车身200、踏杠1、臂组件23、锁定座31和锁定摆臂32。其中臂组件23分别与车身200的底面201和踏杠支座22相连以驱动踏杠1在伸出位置和缩回位置之间移动。换言之，臂组件23的一端与车身200的底面201相连，臂组件23的另一端与踏杠支座22相连，以驱动踏杠1在伸出位置和缩回位置之间移动。
锁定摆臂32在锁定位置和释放位置之间可摆动，用于与锁定座31协作以将踏杠1锁定在缩回位置。可以理解的是，在锁定位置，锁定摆臂32可与锁定座31协作以将踏杠1锁定在缩回位置，并且锁定摆臂32还可与锁定座31协作以释放踏杠1，从而便于踏杠1从缩回位置朝向伸出位置移动。
如图13-15所示，根据本发明实施例的车用踏杠设备100包括踏杠1、伸缩装置2、锁定座31和锁定摆臂32。其中踏杠1在伸出位置和缩回位置之间可移动。伸缩装置2包括踏杠支座22和臂组件23，踏杠1安装在踏杠支座22上，臂组件23与踏杠支座22可枢转 地相连且适于与车辆1000的车身200的底面201可枢转地相连，以驱动踏杠1在伸出位置和缩回位置之间移动。
锁定摆臂32在锁定位置和释放位置之间可移动，其中在锁定位置，锁定摆臂32和锁定座31将踏杠1锁定在缩回位置；在释放位置，锁定摆臂32和锁定座31释放踏杠1。从而便于踏杠1从缩回位置朝向伸出位置移动。
在一些实施例中，踏杠1和踏杠支座22中的一个具有接合部件4，在缩回位置，锁定摆臂32和锁定座32将接合部件4夹持它们之间以锁定踏杠1。换言之，踏杠1具有接合部件4，或者踏杠支座22具有接合部件4，踏杠1移动到缩回位置时，接合部件4可被锁定摆臂32和锁定座31夹持住，从而实现踏杠1的锁定。
在一些具体地实施例中，如图13-16所示，接合部件4包括接合轴41，在缩回位置，锁定摆臂32和锁定座31将接合轴41夹持在它们之间以锁定踏杠1。
在一些实施例中，接合部件4还包括第一支撑耳42和第二支撑耳43，第一支撑耳42和第二支撑耳43彼此间隔开地设置，接合轴41的第一端与第一支撑耳42相连，接合轴41的第二端与第二支撑耳43相连，接合部件4设在踏杠1上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠1上，接合部件4设在踏杠支座22上时，第一支撑耳42和第二支撑耳43彼此间隔开地设在踏杠支座22上。
在一些具体实施例中，如图13和图14所示，锁定座31具有第一卡槽313，锁定摆臂32具有第二卡槽321，在缩回位置，接合部件4被锁定在第一卡槽313和第二卡槽321之间，以将踏杠1锁定在缩回位置。
如图18所示，当锁定摆臂32转动到锁定位置，接合轴41被夹持在锁定摆臂32的第二卡槽321和锁定座31的第一卡槽313之间，通过接合轴41被锁定在第一卡槽313和第二卡槽321之间，由此将踏杠1锁定在缩回位置。
在一些具体实施例中，锁定座31具有延伸臂部311，第一卡槽313设在延伸臂部311的自由端3111(如图14所示的延伸臂部311的下端)，锁定摆臂32具有枢接端322(图15所示的锁定摆臂32的上端)和自由端323(图15所示的锁定摆臂32的下端)，锁定摆臂32的枢接端与锁定座32可枢转地相连，第二卡槽321设在锁定摆臂32的自由端323。
在一些实施例中，如图13-14所示，第一卡槽313和第二卡槽321均为大体V形，但第一卡槽313和第二卡槽321的形状并不限于此，只要接合部件4能够可靠地夹在第一卡槽313和第二卡槽321之间即可。在一个具体示例中，接合部件4包括接合轴41，接合轴41的外周轮廓的一部分与第二卡槽321的内周轮廓相适配，接合轴41的外周轮廓的另一部分与第一卡槽313的内周轮廓相适配，从而可以更好地将接合轴41夹持在第一卡槽313和第二卡槽321之间。
在一些实施例中，接合轴41的横截面为非圆形，例如四边形、六边形等的多边形，其中图13、16-18示出了接合轴41的横截面积正六边形。可以理解的是，接合轴41的横截面并不限于此。
