Embodiment Construction

[0034] see Figure 2 to Figure 4 , the preferred embodiment of the reflector provided by the present invention is integrally formed by metal materials, and its structure mainly includes a reflector panel 4, a support plate 5 and a back plate 6; the support plate 5 is located between the reflector panel 4 and the back plate 6 between. A central hole 10 for setting a correcting mirror is arranged in the center of the reflecting mirror along the axial direction.

[0035] see Figure 5 , the support plate 5 includes an outer frame 51, an inner frame 52 and a reticulated rib 53; Connected, it can ensure that the reflector has a high weight reduction rate and a high natural frequency. The correction mirror is connected with the inner frame 52 through a threaded hole. The outer frame 51 is provided with three sub-frame mounting plates 8 evenly distributed at 120° and three flexible brackets 7 evenly distributed at 120°, and the adjacent sub-frame mounting plates 8 and flexible br...

Abstract

The invention relates to a structural component of a space camera, and in particular to a support-integrated reflector. The support-integrated reflector comprises a reflector panel integrally formed by a metal material, a support plate and a back plate. One side of the support plate is the reflector panel, and the other side of the support plate is the back plate. The support plate comprises an outer frame, an inner frame and net-shaped ribs, the outer frame is positioned on the outer circumference of the support plate, the inner frame is positioned at the center of the support plate, and the net-shaped ribs are positioned between the outer frame and the inner frame. The outer frame is provided with a plurality of sub-frame installing plates and a plurality of flexible brackets. The support-integrated reflector is capable of solving the technical problem that the traditional reflector and the support structure thereof need to be machined, assembled and used alone. The reflector and the support are integrally designed, the traditional reflector support structure is eliminated, and one component is used as the reflector and the support. The weight of the whole device and the number of the parts can be reduced, the reflecting cost is decreased, and the rigidity of the integrated structure is improved.

Description

technical field [0001] The invention relates to a structural component of a space camera, in particular to a supporting integrated reflector. Background technique [0002] The mirror and its supporting structure occupy a very important position in the structural components of the space remote sensing camera. The surface shape accuracy of the mirror is directly related to the imaging performance of the space camera. Traditional reflectors and supporting structures are usually processed separately from different materials, and then assembled and formed by gluing, screwing and other connection methods. Traditional reflector structures such as figure 1 As shown, the mirror 1 is mounted on a conventional support plate 3 through a central axis 2 . The reflector 1, the central axis 2 and the traditional support plate 3 are assembled and used after separate processing. The three need to be glued and screwed. The stress generated during the assembly process will reduce the surface ...
