Abstract

The invention discloses an unfolding in-place locking device and a spacecraft, and relates to the technical field of solar wing accessories. The unfolding in-place locking device comprises a locking shell, a swing arm and a lock pin. The locking shell is provided with a shell inner cavity and a locking groove; the lock pin can reciprocate along the inner cavity of the shell, and the head end of the lock pin can stretch out of the inner cavity of the shell and stretch into the locking groove. A first elastic piece is arranged in an inner cavity of the shell, and a boss extending out of the inner cavity of the shell is arranged on the lock pin. The swing arm is provided with a swing arm stopping part used for stopping the boss, and the inner side of the swing arm stopping part and a swing arm body of the swing arm form a swing arm groove capable of containing the boss. The swing arm is hinged to the locking shell so that stopping of the swing arm stopping part on the boss can be relieved under the action of external force, and the boss can be disengaged from the swing arm groove. The spacecraft comprises the unfolding in-place locking device. According to the unfolding in-place locking device and the spacecraft, the technical problem that the locking reliability of an unfolding mechanism is improved to a certain degree is solved.

Description

technical field [0001] The invention relates to the technical field of solar wing accessories, in particular to a deployment-in-position locking device and a spacecraft. Background technique [0002] Solar wings, or solar panels, are devices that collect solar energy and are usually used to power satellites and spacecraft. [0003] With the continuous enhancement of satellite functions, the demand for energy has correspondingly increased, and the power consumption of the entire satellite cannot be satisfied by simply relying on the area of ​​the body-mounted windsurfing board, so the deployment of the windsurfing board has been widely used. The key component of unfolding the windsurfing board is the unfolding mechanism. When the unfolding windsurfing board is fully unfolded, the reliability of the locking mechanism of the unfolding windsurfing board directly affects the reliability of the unfolding windsurfing board. SUMMARY OF THE INVENTION [0004] The purpose of the pr...
