The invention discloses an asteroid landing robot separating and releasing mechanism with an adjustable separating speed, and belongs to the technical field of spacecraft mechanisms. The separating and releasing mechanism comprises a storage box body, a cabin door device, a sliding rail structure, a separating power assembly, a limiting clamping groove structure, a check block positioning structure and a motion unlocking mechanism. After the separating and releasing mechanism receives a separating and releasing instruction, the cabin door locking and releasing mechanism is electrified to work, the locking constraint on the cabin door is relieved, and the cabin door body is opened under the driving of the torsional spring and is kept locked after being opened to a preset angle; at the moment, the motion unlocking mechanism is powered on to work, motion limitation on a push plate in the separation power assembly is relieved, the landing robot slides out of an opened cabin door outlet along a sliding rail structure under the action of elastic restoring force of a spring, and then release is completed. The landing robot has the advantages that the separation speed of the landing robot can be adjusted, the cabin door cannot rebound or shake after being opened, and the landing robot cannot collide with the cabin door body during separation.

    本发明公开一种分离速度可调节的小行星着陆机器人分离释放机构,属于航天器机构技术领域。所述分离释放机构包括收纳箱体、舱门装置、滑轨结构、分离动力组件、限位卡槽结构、挡块定位结构以及运动解锁机构;当分离释放机构收到分离释放指令后,舱门锁紧与释放机构通电工作,解除对舱门的锁紧约束,舱门本体在扭簧驱动下打开,且打开到预定角度后保持锁定;此时运动解锁机构通电工作,解除对分离动力组件中推板的运动限制,着陆机器人在弹簧的弹性恢复力作用下沿滑轨结构从打开的舱门出口中滑出,进而完成释放。本发明具有着陆机器人分离速度可调节、舱门打开后不会反弹或晃动、分离时着陆机器人与舱门本体不会发生碰撞等优点。
