Embodiment Construction

[0042] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] see Figure 1 ~ Figure 3 shown;

[0044] A small space camera support structure of the present invention, the support structure comprises:

[0045] a central support structure 1 with front and rear ends; and

[0046] An adjustment structure 2 connected to the front end of the middle support structure 1, the adjustment structure 2 is used to adjust the position of the main mirror and the secondary mirror of the camera;

[0047] The end of the adjustment structure 2 away from the middle support structure 1 is connected with a secondary mirror support structure 3, and the secondary mirror support structure 3 is used to connect with the secondary mirror and can support the camera secondary mirror;

[0048] The support structure also include...

Abstract

The invention discloses a small space camera supporting structure. The small space camera supporting structure comprises a middle supporting structure provided with a front end and a rear end, an adjusting structure connected to the front end of the middle supporting structure, a secondary mirror supporting structure connected to one end, away from the middle supporting structure, of the adjusting structure, and a main backboard connected to the rear end of the middle supporting structure, wherein the main backboard is used for connecting a primary mirror of a camera to supporting legs of the camera. Through the secondary mirror supporting structure and the middle supporting structure, the problems of large machining cutting amount and high casting cost caused by limitation of three secondary mirror supporting rods of an integrally-formed supporting structure are solved; an external connecting ring is additionally arranged on the secondary mirror supporting ring, so the rigidity of parts is improved, the problem that the three integrated secondary mirror supporting rods are insufficient in rigidity and prone to deformation is solved, and machining manufacturability is improved; and through the installation mode that the secondary mirror assembly is installed on the secondary mirror supporting ring firstly and then installed and adjusted, the hole site and form and location tolerance requirements of a secondary mirror interface are avoided, and an assembly process is improved.

Description

technical field [0001] The invention relates to the technical field of space optical remote sensing, in particular to a support structure for a small space camera. Background technique [0002] Space remote sensing (especially infrared remote sensing technology) has broad application prospects in resource surveys, environmental monitoring, atmospheric and ocean observations, earth radiation measurements, astronomical observations, and military affairs. important development trend. Small cameras are compact in structure and small in size, and the effect of light weight reduction is limited. Therefore, in the design process of the camera, the processing technology and assembly technology of the camera structure are taken into account at the same time, so as to better control the project cost and shorten the production cycle. [0003] Existing support structures for small and medium-sized cameras mainly include A-shaped truss structures and cylinder structures, which are furth...
