Bionic multistable deployable mechanism
The invention discloses a bionic multistable deployable mechanism which comprises a bottom plate, a quadrilateral frame, a trilateral frame and a movable rod, wherein the quadrilateral frame, the trilateral frame and the movable rod are arranged on the bottom plate. A connecting shaft is arranged on the bottom plate, a straight sliding groove is formed in the end of the connecting shaft, and a movable rod is installed in the straight sliding groove in a sliding mode. The quadrilateral frame is of a deformable frame structure formed by rotatably connecting four rod bodies and has the use states that the quadrilateral frame is folded to an isosceles triangle, the bottom edge of the isosceles triangle is concave inwards and the bottom edge of the isosceles triangle is convex outwards. Each trilateral frame is of a deformable frame structure formed by rotationally connecting two rod bodies and a movable rod, and the two trilateral frames both have the use state that the trilateral frames and the movable rod are coaxially arranged after being folded; the movable rod is installed on the bottom plate in a sliding mode, and the sliding check block is used for abutting against a baffle of the quadrilateral frame so as to maintain the deformation state. Through mutual combination of the structures, mutual switching of five forms can be achieved, and therefore the problem that an existing deployable mechanism is insufficient in convertible form is practically solved.
本发明公开了一种仿生多稳态可展机构，包括底板、以及设于底板上的四边形框架、三边形框架、以及活动杆；该底板上设有设有连接轴，连接轴的端部设有直滑槽，直滑槽内滑动安装有活动杆；该四边形框架为四杆体转动连接而成的可形变框架结构，具备折叠至等腰三角形、等腰三角形底边内凹、以及等腰三角形底边外凸的使用状态；该三边形框架为两根杆体与活动杆转动连接而成的可形变框架结构，且两三边形框架均具备折叠至与活动杆同轴线布置的使用状态；该活动杆滑动安装于底板上，且滑动挡块用于与四边形框架的挡板抵接以维持形变状态；通过上述结构的相互组合下，能够实现五种形态的相互切换，从而切实解决了现有可展机构可变换形态不足的问题。
