技术领域technical field
本发明涉及一种锁紧装置,适用于空间可重复展开机构,可重复锁紧及解锁。The invention relates to a locking device, which is suitable for a space repeatable unfolding mechanism and can be repeatedly locked and unlocked.
背景技术Background technique
在进行月球、火星等深空探测时,漫游车上的很多可重复展开机构需要锁紧,例如,机械臂系统是漫游车上的主要装置,在漫游车发射、飞行、着陆、行走过程中,机械臂需要可靠的锁紧,在进行就位探测时,机械臂需要解锁、展开,以便携带有效载荷进行就位探测作业。锁紧装置是保障可重复展开机构安全的一个关键机构。在不同的状态下,锁紧装置需要具有不同的锁紧功能。在发射、着陆过程中,由于存在较大的加速度和冲击载荷,需要锁紧装置对需锁紧装置进行稳定的约束,采用过约束的形式保证锁紧的可靠性;而在星球表面的行走、作业过程中,锁紧装置通常对需锁紧装置进行不完全约束,需要一定的柔性和灵活性以保证需锁紧装置能够顺利的多次重复锁紧和展开。由于受发射能力、漫游车体积、负载能力的限制,锁紧装置需要结构简单、体积小、重量轻,才能更好的完成工作需要。When conducting deep space exploration on the moon and Mars, many repeatable deployable mechanisms on the rover need to be locked. For example, the robotic arm system is the main device on the rover. During the launch, flight, landing, and walking of the rover, The robotic arm needs to be locked reliably. When performing in-position detection, the robotic arm needs to be unlocked and unfolded so as to carry the payload for in-position detection. The locking device is a key mechanism to ensure the safety of the repeatable deployable mechanism. In different states, the locking device needs to have different locking functions. In the process of launch and landing, due to the large acceleration and impact load, the locking device is required to constrain the device to be locked stably, and the over-constrained form is used to ensure the reliability of locking; while walking on the surface of the planet, During operation, the locking device usually performs incomplete restraint on the device to be locked, and requires a certain degree of flexibility and flexibility to ensure that the device to be locked can be repeatedly locked and deployed smoothly. Due to the limitations of launch capability, rover volume, and load capacity, the locking device needs to be simple in structure, small in size, and light in weight in order to better complete the work.
