specific Embodiment approach 1

[0024] Specific implementation mode one: combine Figure 1~5 Describe this embodiment, a space flexible arm compression release mechanism for external force unlocking, which includes a base 1, a cover plate 2, a pull rod shaft 3, a first support seat 4, several second support seats 5, and several locking hooks 6 , several lower locking hooks 7 and some compression springs 8, the number of the second support base 5, upper locking hooks 6, lower locking hooks 7 and compression springs 8 is equal, and the base 1 is fixed on the satellite deck 101 One side of the cover plate 2 is rotatably connected with the base 1, the top of the base 1 is provided with a first through groove 1-1 along its length direction, and the cover plate 2 is provided with a second through groove 2-1 along its length direction , when the flexible arm 100 is compressed, the first through-slot 1-1 and the second through-slot 2-1 are set up and down, and the flexible arm 100 is placed in the first through-slot...

specific Embodiment approach 2

[0032] Specific implementation mode two: combination Figure 1~4 To illustrate this embodiment, the cover plate 2 and the base 1 are rotatably connected through several pin shafts 15, and the pin shafts 15 are arranged on the side of the base 1 away from the first support base 4, and the several pin shafts 15 are all parallel to the base The seat 1 is provided, and each bearing pin 15 is sleeved with a torsion spring 16. In such a design, the two ends of the torsion spring are fixedly connected to the cover plate 2 and the base 1 respectively, and the torsion spring 16 fitted on the pin shaft 15 exerts a torsion moment on the cover plate 2 . Other compositions and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0033] Specific implementation mode three: combination Figure 1~4 To describe this embodiment, the number of the pin shafts 15 is two. Such a design ensures a stable connection between the cover plate 2 and the base 1 and at the same time reduces production costs. Other compositions and connections are the same as in the second embodiment.

Abstract

The invention relates to an external force unlocked spatial flexible arm compressing and releasing mechanism and belongs to the field of spatial technical researches. The external force unlocked spatial flexible arm compressing and releasing mechanism solves the problem that an existing spatial flexible arm which is launched is easily damaged under the action of vibration and impact loads. One side of a cover plate is rotatably connected to a substrate; a first straight slot is formed in the top of the substrate along the length direction of the substrate; a second straight slot is formed in the cover plate along the length direction of the cover plate; a first supporting seat and a plurality of second supporting seats are fixedly connected to one side face of the substrate; the upper surface of the first supporting seat is fixedly connected to a first lug plate; the upper surface of each second supporting seat is parallelly and fixedly connected to a second lug plate and a third lug plate; a through hole is formed in each lug plate; pull rod shafts are successively arranged through the plurality of through holes; a lower lock hook is fixedly mounted on the pull rod shaft between the second lug plate and the third lug plate; and a compression spring sleeves the pull rod shaft between the lower lock hook and the third lug plate. According to the external force unlocked spatial flexible arm compressing and releasing mechanism provided by the invention, the spatial flexible arm is prevented from being damaged in the launching process.

Description

technical field [0001] The invention relates to a space flexible arm compression release mechanism unlocked by external force, which belongs to the field of space technology research. Background technique [0002] The world launches an average of 80-130 satellites per year, but 2-3 satellites fail to enter orbit correctly, and 5-10 satellites correctly enter orbit, and 5-10 fail at the beginning of their life (the first 30 days after entering orbit) , which resulted in huge economic losses. For example, after my country's Xinnuo-2 satellite was launched on October 29, 2006, although the satellite's orbit was successfully determined, and the satellite's measurement and control, attitude and orbit control subsystems were in good condition, however, due to the solar sail The second deployment of the board and the deployment of the antenna were not completed, and the satellite could not work normally. This satellite, which cost 2 billion yuan and had a design life of 15 years, i...
