The invention discloses an on-orbit docking device and docking system for a spacecraft, relates to the technical field of spacecraft devices, and is used for improving docking tolerance and reducing power consumption. The docking device is installed on a main spacecraft used for docking a target spacecraft, the docking device is a rod-shaped mechanism, the docking device comprises a control section, a buffer section and a capture section, the capture section comprises a limiting module and a capture module capable of inclining in any direction, and the capture module is used for obtaining attitude information and position information of the target spacecraft. The capturing section is in butt joint with or separated from the target spacecraft through electromagnetic force, and the limiting module is used for limiting the capturing section; the control section comprises a control unit, and the control unit is used for controlling the main spacecraft to approach the target spacecraft according to the attitude information and the position information and sending an electromagnetic adjustment instruction to the capture module to control the capture module to adsorb or repel the target spacecraft; the buffer section is used for absorbing impact. Through the butt joint device, the butt joint precision requirement can be lowered, and large-tolerance butt joint is achieved.

    本发明公开了一种用于航天器的在轨对接装置和对接系统,涉及航天器装置技术领域,用于提高对接容差降低功耗。对接装置安装在用于对接目标航天器的主航天器上,对接装置为杆状机构,对接装置包括控制段、缓冲段以及捕获段,其中,捕获段包括限位模块和能够向任意方向倾斜的捕获模块,捕获模块用于获取目标航天器的姿态信息和位置信息,并通过电磁力与目标航天器对接或分离,限位模块用于对捕获段进行限位;控制段包括控制单元,控制单元用于依据姿态信息和位置信息控制主航天器靠近目标航天器,并向捕获模块发出电磁调节指令以控制捕获模块吸附或排斥目标航天器;缓冲段用于吸收冲击。通过对接装置能够降低对接的精度要求,实现大容差对接。
