如图1-4所示，根据本申请实施例的车辆1000包括车身200和车用踏板设备100，车用踏板设备100安装在车身的底面210，即车底盘。
如图1-图4所示，车辆1000包括车门300，车用踏板设备100邻近车门300设置且位于车门300下方。在图1-4所示的示例中，车辆1000具有两个车门300，车门300为侧门。本申请并不限于此，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板设备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板设备100。
下面描述根据本申请实施例的车用踏板设备。
如图5、图6和图7所示，根据本申请实施例的车用踏板设备100包括踏板1、升降装置2和驱动器3。
升降装置2包括臂组件23，臂组件23包括多对臂，每一对臂包括第一臂231和第二臂232，且每一对臂的第二臂232的第二端(图5中第二臂232的下端)与踏板1可枢转地连接，且多对臂至少包括第一主动臂对和第二主动臂对。如图5-7所示，臂组件23中有两个主动臂对201，一个为第一主动臂对，另一个为第二主动臂对。
第一主动臂对的第一臂231的第二端(图中第一主动臂对的第一臂231的上端)与第二主动臂对的第一臂231的第二端(图中第二主动臂对的第一臂231的上端)通过齿轮传动连接，和/或，第一主动臂对的第二臂232的第二端(图中第一主动臂对的第二臂232的下端)与第二主动臂对的第二臂232的第二端(图中第二主动臂对的第二臂232的下端)通过齿轮传动连接。换言之，第一主动臂对和第二主动臂对可以仅第一臂231的第二端齿轮传动连接，还可以仅第二臂232的第二端齿轮传动连接，还可以第一臂231的第二端齿轮传动连接且第二臂232的第二端齿轮传动连接。
每一对臂中的第一臂231的第一端和第二臂232的第一端与驱动器3可枢转地连接，用于驱动臂组件23撑开和收拢以调节踏板1的水平高度。如图1、图5和图6所示，驱动器3为线性 驱动器，线性驱动器可伸长和可缩回以进行直线运动，线性驱动器缩回时，第一臂231和第二臂232中的至少一个臂朝向彼此收拢在一起的方向转动，从而踏板1朝向车身的底面210靠拢，以增大踏板1的高度。线性驱动器伸长时，第一臂231和第二臂232中的至少一个臂可从彼此收拢在一起朝向彼此撑开的方向转动，从而踏板1朝向背离车身的底面210的方向移动，以减小踏板1的高度。具体地，线性驱动器可以为液压缸、气缸或电动推杆等。

如图2所示，第一臂231和第二臂232处于完全收拢状态时，踏板1与在上下方向上与车身的底面210之间的距离最近以位于侧杠位置，踏板1位于车身200的侧面的下沿处，且踏板1在车身200的宽度方向(图1中前后方向)上超出车身200的宽度，从而踏板1可以用作车身200的保险杠而起到防护功能，以保护车身200防止车辆1000被撞击或刮蹭。
如图3所示，第一臂231和第二臂232从完全收拢状态开始撑开到第一撑开状态时，踏板1向下运动远离侧杠位置且高于地面，人们可以通过踏板1上车。
如图4所示，第一臂231和第二臂232从第一撑开状态继续撑开到第二撑开状态时，踏板1继续向下运动以与地面相抵靠，并顶起车身200，车辆1000的轮胎与地面脱离开，以便进行车辆修理，从而起到了千斤顶的作用。
