Embodiment Construction
[0022] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0023] The invention provides a space airbag release device, comprising an airbag, a storage mechanism, an end cover locking and unlocking mechanism, an airbag locking and unlocking mechanism and an inflation device, a thrust spring is provided at the bottom of the storage mechanism, and an end cover is provided at the top; the airbag, the airbag lock Both the locking mechanism and the inflation device are placed in the receiving mechanism. Such as Figure 1 to Figure 5 As shown, the storage mechanism in this embodiment is realized by the cylinder cover 1, the cylinder body 2, the rotating shaft 3, the cylinder bottom 4, the push plate 9 and the thrust spring 10, and the locking and unlocking mechanism of the end cover is achieved by the torsion spring 5 and the electromagnet. Sheet 6, electromagnet 7 and electromagnet bracket 8 are realized, and the airb...

The invention discloses a release device for a space airbag. The device comprises the airbag, a containing mechanism, an end cover locking and unlocking mechanism, an airbag locking and unlocking mechanism and an air inflation device. A thrust spring is fixed to the bottom of the containing mechanism, and an end cover is arranged at the top of the containing mechanism; the airbag, the airbag locking and unlocking mechanism and the air inflation device are arranged in the containing mechanism, the airbag is folded and then placed on the thrust spring, an air inflation pipe of the airbag is connected with the air inflation device through a hose, the junction of the hose is locked through the airbag locking and unlocking mechanism, the end cover is closed and locked through the end cover locking and unlocking mechanism, and the thrust spring is in a compressed state; when the airbag needs to be released, the end cover is unlocked through the end cover locking and unlocking mechanism and opened, the airbag is ejected out of the containing mechanism by the thrust spring, and the air inflation device is started for inflating the airbag; the air inflation device is started for inflating the airbag, the airbag is ejected out of the containing mechanism by the thrust spring, after air inflation on the airbag is ended, the junction of the hose is unlocked through the airbag locking and unlocking mechanism, and the air inflation pipe of the airbag is separated from the air inflation device. According to the release device for the space airbag, the comprehensive demand for storage, protection, release and air inflation on the airbag in the space environment can be met.
Description
technical field [0001] The invention belongs to the technical field of space product structure and mechanism design, and in particular relates to a space airbag release device. Background technique [0002] Space exploration has important scientific value and engineering significance. At present, space products such as artificial satellites in space are mostly metal hard products, which have certain requirements for launch cost, volume and weight. The application of airbag soft space products has greatly expanded the application fields of space products. Foldable airbag products are characterized by small size and light weight when launched, and can maintain a certain shape after being deployed in space, and will not or rarely produce space junk. Therefore, space airbag products can be applied in space environment detection, construction of special-shaped structures, space junk capture, ground instrument observation, etc. [0003] Different application requirements determ...
