The invention discloses an expandable three-dimensional foldable truss bearing structure for space. The expandable three-dimensional foldable truss bearing structure comprises a vertical truss, a circumferential truss, a radial truss, a truss storage box and an electromechanical interface. The vertical truss, the radial truss, the central truss and the circumferential truss are used as main supports, the upper truss and the lower truss are connected with other structures through the flexible connecting mechanisms correspondingly, the track control electric thruster assemblies are arranged in the middle truss storage box, and electromechanical equipment mounting positions are reserved in other parts of the trusses. The large three-dimensional foldable truss bearing structure with the high storage ratio can be launched at a time and formed at a time after being unfolded in orbit, the modular assembly capacity of an ultra-large space system is greatly improved, the requirements for strength and light weight are met, and meanwhile the large three-dimensional foldable truss bearing structure has the advantages of being flexible in electromechanical connection, capable of maintaining a thruster structure through an omni-directional independent orbit, flexible in equipment installation and the like.

    本发明公开了一种空间用可扩展的三维可折展桁架承力结构,包括:垂直桁架、周向桁架、径向桁架、桁架储存盒、机电接口。本发明通过利用垂直桁架、径向桁架、中心桁架和周向桁架作为主要支撑,上下桁架通过柔性连接机构分别与其他结构连接,中间桁架储存盒布设轨控电推力器组件,在桁架其它部位预留机电设备安装位置。高收纳比大型三维可折展桁架承力结构可一次发射,在轨展开后一次成型,大大提高了超大型空间系统模块化装配能力,满足强度和轻量化要求,同时具备柔性机电连接、全向独立轨道维持推力器结构、设备安装灵活等特点。
