Abstract

A large-bearing low-impact connecting and separating device based on memory alloy driving comprises a memory alloy driving assembly (1), a deblocking transmission assembly (2), a connecting and separating assembly (3) and a buffering capturing assembly (4), wherein the memory alloy driving assembly (1) can overcome pulling force of a tension spring (6) after being charged with electricity to drive a triggering shaft (10) to rotate, so as to relieve limitation on a primary swinging arm (9); the primary swinging arm (9) rotates to relieve limitation on a secondary swinging arm (8); the secondary swinging arm (8) rotates to relieve limitation on a main force transmission nut (17); the main force transmission nut (17) rotates to enable a bearing rod (22) to conduct linear motion along a center hole of a guide seat (23), so as to realize deblocking separation. The large-bearing low-impact connecting and separating device can realize firm connection and deblocking separation of star arrows as well as stars and load, and has the characteristics of being large in bearing, low in impact, high in reliability and reusable.

Description

technical field [0001] The invention relates to a connection and separation device, in particular to a connection and separation device driven by memory alloy. Background technique [0002] In aerospace missions, the mechanism that realizes the connection and separation functions between the spacecraft body and components, between the cabins, between the spacecraft and the launch vehicle, and between spacecraft is called the connection and separation device. A key component in a load separation system. At present, most of the connection and separation devices used in the aerospace field are based on the principle of pyrotechnic action, that is, cutting, punching or pushing out the connecting parts through the impact force of the explosion to achieve separation. However, this kind of device has insurmountable shortcomings such as strong separation impact, obvious additional pollution and non-reusable. [0003] At present, the separation device using memory alloy as the driv...
