一种车厢及其底门
摘要：
本发明公开了一种车厢的底门，包括伸缩缸和至少两组门体，每组门体设有一组传动机构，传动机构包括转轴和传动杆，转轴通过传动杆连接门体，以便转轴转动时带动门体转动；各转轴均由伸缩缸驱动转动，且至少两个转轴能够先后受到伸缩缸的驱动而转动。各转轴能够先后受到伸缩缸的驱动而转动，使得与各转轴相对应的各组门体按一定顺序依次开启。伸缩缸只需始终提供开启一组门体所需的作用力，与现有技术相比，底门开启时所需的作用力较小，降低了对伸缩缸作用力的需求，比较容易实现，减小了伸缩缸的体积，节省空间，降低自重。另外，也减小了开启过程中的冲击力，提高了整个底门的可靠性。本发明还公开了一种具有上述底门的车厢。
摘要（英）：

A bottom door of a carriage includes a telescoping cylinder and at least two sets of door bodies, each set of the door body is provided with one set of driving mechanisms, each of the driving mechanisms includes a rotating shaft and a driving rod, and the rotating shaft is connected with the respective door body by the driving rod, to allow the door body to be driven to rotate when the rotating shaft rotates; each of the rotating shaft is driven to rotate by the telescoping cylinder, and at least two of the rotating shafts are configured to be driven to rotate successively by the telescoping cylinder.
