Embodiment Construction

[0040] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0041] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0042] Such as Figure 1-Figure 8 As shown, a radial locking capture lock for a spacecraft includes an active end 1 installed on the active aircraft and a passive end 2 installed on the passive aircraft. The passive end 2 has a tapered structure. The end 1 includes a housing assembly, a drive assembly, a transmission assembly and a locking assembly. The housing assembly is used to support and connect the drive assembly, the transmission assembly and the lock assembly. The drive assembly drives the transmission assembly so that the transmission assembly will The rotary motion is converted into linear motion. The transmission assembly controls the radial reciprocating movement ...

Abstract

A radial snap-on capture lock for a spacecraft and a working method thereof are provided, the capture lock includes an active end mounted on the active aircraft and a passive end mounted on the passive aircraft, the passive end is of a conical structure, the active end includes a housing assembly, Drive Assembly, Drive assembly and latch assembly, the housing assembly is used for supporting, connecting the drive assembly, Drive assembly and latch assembly, The drive assembly drives the drive assembly to convert the rotary motion into linear motion, the drive assembly controls the radial reciprocating motion of the latch assembly, the latch assembly clamps the passive end when the latch assembly radially extends out of the housing assembly, and the latch assembly releases the passive end when the latch assembly radially retracts the housing assembly. The invention solves the problems of complex system, large quality, poor universality and the like of the prior docking mechanism technology, and realizes the capture, locking and release of low disturbance in the docking process of the aircraft.

Description

Technical field [0001] The invention belongs to the technical field of spacecraft on-orbit docking, and in particular relates to a radial locking type capture lock for a spacecraft and a working method thereof. Background technique [0002] The process of spacecraft docking in orbit includes five stages: initial acquisition and initial docking, coaxial attitude adjustment of the docking plane of the aircraft, telecommunication interface connection, rigid common body flight, and unlocking separation. In the capture phase, a capture lock is usually used to complete the initial contact and lock between the two aircraft to establish a preliminary connection. At present, not only in the field of aircraft docking, but also in space missions such as my country’s space station construction, aircraft in-orbit services, future space station material storage and transportation, and space manipulator material transfer, the docking link of cooperative targets is required. Capture and lock are...
