The invention provides a swing arm mechanism for pressing and releasing a satellite effective load. The swing arm mechanism comprises an unlocking assembly (1), a triangular frame (2), a turnover assembly (3) and other components. When a satellite is launched, the four sets of swing arm mechanisms are evenly distributed on the periphery of an effective load to form a four-point eight-rod supporting structure, a stable and closed structural system is formed, and the effective load is pressed to bear static and dynamic mechanical loads in all directions. After a satellite enters an orbit, under the control of a ground remote control instruction, the four sets of swing arm mechanisms are divided into two groups, the two sets of diagonal swing arm mechanisms are unlocked and unfolded at the same time, the microswitch is triggered after the swing arm mechanisms are unfolded in place, in-place locking telemetry signals are generated, and effective loads are released. The invention has the characteristics of large bearing capacity, high rigidity, low impact and light weight, and can be used in the field of long-distance compaction and release of large effective loads such as space cameras, microwave antennas, space telescopes, laser communication terminals and the like.
本发明提供了一种用于卫星有效载荷压紧释放的摆臂机构,包括解锁组件(1)、三角框架(2)、翻转组件(3)等构件;卫星发射时四套摆臂机构均布在有效载荷四周,形成四点八杆支承构型,成为稳定封闭的结构系统,实现有效载荷压紧,承受各个方向的静动态力学载荷;卫星入轨后在地面遥控指令控制下,四套摆臂机构分成两组,对角两套摆臂机构同时解锁展开,展开到位后触发微动开关,产生锁定到位遥测信号,释放有效载荷。本发明具有大承载、高刚度、低冲击和轻量化的特点,可用于空间相机、微波天线、空间望远镜、激光通信终端等大型有效载荷的远距离压紧释放领域。
