Problems solved by technology

In the current technology, the guide mechanism is usually used to bear the external load borne by the docking mechanism assembly. When the external load is too large, the guide mechanism will be deformed, and in severe cases, it will be damaged and the electrical connection will be damaged under load, even if the electrical connector is not damaged. , during the separation process and the next docking process, the electrical connector cannot be reliably separated or mated again

Embodiment Construction

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] The three-stage fault-tolerant docking mechanism of the present invention has a three-stage fault tolerance of the rail impact, including the hand claw 1, the guide rod 2 and the pair block 3, such as figure 1 As shown; where the hand claw 1 is mounted at the active end 6, the active end 6 is mounted on the space tray. The pairing block 3 is mounted on the active end 6 and the passive end 7, the passive end 7 mounting the space tray, through the hand claw 1, the guide rod 2, the active end 6 and the passive end 7 docking process Capacity-based, realize the precision plugging of the active end pair and the passive electrical connector 10 on the surface of the electrical connector, and implements the impact resistance after the plug, the specific scheme is as follows:

[0022] The hand claws 1 circumferentially, and the end is mounted on the lifting stage 9 m...

Abstract

The invention discloses an on-orbit impact resistant three-stage fault-tolerant butt joint mechanism and realizes first-stage fault tolerance between a driving end and a driven end through matching ofa gripper grabbing end mounted at the driving end and a butt joint groove which is circumferentially designed at the driven end and matched with the grabbing end in shape. A guide rod installed on anend face of the driving end and a slot designed in an end face of the driven end are matched and connected in an inserted mode, secondary fault tolerance between the driving end and the driven end isachieved, three-stage fault-tolerant stage on-orbit impact resistance between the driving end and the driven end is achieved through matched insertion connection of tooth-shaped butt joint blocks installed at the driving end and the driven end in the circumferential direction. The mechanism is advantaged in that a guiding problem of correct plugging of an electric connector is solved through first two stages, through third-stage fault tolerance, an electric connector is not stressed after being plugged.

Description

Technical field [0001] The present invention belongs to the field of cargo transportation transportation, specifically a three-level fault-tolerant docking mechanism against rail impact. Background technique [0002] With the development of my country's aerospace technology, the establishment and development of space stations is an important integration and reflection of space technology. In the future, my country's space station is in the rail flight, and the supply of space goods resources is required. It is necessary to deliver ground materials to the space station, and the space cargo is docked in the space station. [0003] The space cargo will be delivered from the freight spacer to the space predetermined area, which pulls the pallet system and transferred the pallet system and transferred to the space station clip and unlocked. [0004] The main function of the docking mechanism completes the docking is to ensure the electrical passage and information path between the spa...
