The invention relates to the technical field of expandable shelters, and provides a synchronizing mechanism for an expandable shelter. The synchronizing mechanism for the expandable shelter comprisesa rotatable gear, two driving rods and a driving element, wherein the two driving rods are used for respectively providing driving force for two ascending and descending mechanisms of the expandable shelter; the driving element is used for providing linear driving force; each of the two driving rods is provided with a rack engaged with the gear; teeth of the two racks are arranged in a way of being directly facing each other; one of the driving rods is connected with the output end of the driving element; and in addition, the direction of the driving force of the driving element is consistentwith the length direction of the driving rod. The expandable shelter is provided, comprises a shelter floorboard, and also comprises two ascending and descending mechanisms used for lifting the shelter floorboard and the synchronizing mechanism for the expandable shelter; and the two driving rods are respectively connected with the two ascending and descending mechanisms. Through the cooperation of the gear and the racks, the synchronous supply of driving force of the two ascending and descending mechanisms can be realized only through one driving element; the structure is simple; the realization is easy; and the cost is low, but the reliability is high.
本发明涉及扩展方舱技术领域,提供了一种用于扩展方舱的同步机构,包括可转动的齿轮、用于分别为扩展方舱的两个升降机构提供驱动力的两根驱动杆以及提供线性驱动力的驱动件,两根所述驱动杆均具有与所述齿轮捏合的齿条,两个所述齿条的齿正对设置,其中一根所述驱动杆与所述驱动件的输出端连接,且所述驱动件的驱动力的方向与该驱动杆的长度方向一致。提供一种扩展方舱,包括方舱地板,还包括用于举升所述方舱地板的两个升降机构以及上述的用于扩展方舱的同步机构,两根所述驱动杆分别与两个所述升降机构连接。本发明通过齿轮齿条的配合,只需要一个驱动件即可实现两个升降机构的驱动力同步供给,结构简单,易于实现,成本低但可靠性高。
