Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 As shown, a comprehensive main support backboard suitable for light-duty space cameras, the backboard includes: ribs 4, embedded parts 6, main reflector mounts 7, camera leg mounts 8 and panels 9; The panel 9 has a ring structure, with a ring rib II3 on ​​the circumference of the inner ring, and a ring rib I2 on the circumference of the outer ring; the panel 9, the ring rib I2 and the ring rib II3 form a silicon carbide substrate 1 . The embedded part 6 is arranged in the installation step hole 5 on the panel 9, and fits through gluing, wherein the installation step hole 5 is stepped, which can provide positioning constraints for the gluing of the embedded part 6, And it bears the axial tension of the embedded part 6, and there is a gap of 0.01mm-0.05mm between them for storing the adhesive. Such as figure 2 As sho...

Abstract

A comprehensive main support backplane for a light-weight space camera relates to the field of space optical remote sensing technology, and solves the problem that a light-weight space camera cannot meet the strict quality requirements, thermal stability requirements and mechanical performance requirements of the whole machine. The comprehensive main support backboard of the present invention mainly includes panels, reinforcing ribs, embedded parts and various installation interfaces. The panel is a circular rotationally symmetrical structure, which reduces the local deformation of the structure under the action of gravity and temperature; the reinforcement ribs are evenly distributed on the inner and outer ring circumferences; the distribution of the reinforcement ribs forms a triangular reinforcement hole, which improves the stability of the structure The embedded parts are distributed in the installation interface to improve the stability of the threaded connection; the present invention combines the functions of the main bearing plate of the camera and the supporting back plate of the main mirror, and greatly improves the mechanical and thermal performance of the camera. Improve the utilization rate and light weight of camera components.

Description

technical field [0001] The invention relates to a comprehensive main support backboard suitable for a light-duty space camera, which belongs to the technical field of space optical remote sensing. Background technique [0002] The main load-bearing plate of the space camera is used to support the space camera in the satellite platform. Its main function is to support the optical-mechanical structure of the entire camera, provide the mechanical interface of the camera legs, electrical box, main load-bearing frame and other components, and protect the space. The internal structure components of the camera ensure the performance of the space camera. The main reflector supporting back plate is used to support the main reflector to ensure the surface quality and spatial position of the reflector. [0003] In the field of space optical remote sensing, the main bearing backplane of the camera and the supporting backplane of the mirror are usually two different structures; the main...
