Abstract

A high-rigidity self-expanding sunshade belongs to the field of aerospace technology; the sunshade is designed to solve the technical problems of complex structure system, low positioning accuracy, and low rigidity; the upper mount and the lower mount of the sunshade are both equipped with light Holes, and a plurality of spring retracting grooves are evenly arranged in the circumferential direction, and the connecting block mounting holes are arranged in the spring retracting grooves. The retaining ring is arranged between the spring retracting grooves and the light hole, and the upper mounting seat is connected to the lower mounting seat through a strip spring group. , the driving spring and the shading cloth are arranged between the upper mounting base and the lower mounting base, the unlocker is fixed on the side wall of the lower mounting base by screws, the unlocker breaks the locking rope, and the driving spring drives the upper mounting base to separate from the lower mounting base, Drive the shading cloth to unfold, and the ribbon spring self-expands from the folded and bent state to the straight state, realizing the self-expanding of the shading cover with high stiffness; the shading cover has high reliability, self-expanding, self-locking, simple structure, light weight and high rigidity , The advantages of high expansion precision and large compression ratio.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a high-rigidity self-expanding sunshield. Background technique [0002] The hood is an important part of the satellite optical remote sensing system, which is mainly used to block the external stray light from entering the optical system to improve the imaging quality or detection performance. Conventional hoods are usually designed with a fixed size and made of metal or composite materials. In order to meet the requirements of the optical system, the hood is often large in size, resulting in wasted space and increased launch costs. For large-diameter hoods, the size is also Will be limited by the rocket fairing. The deployable hood that is folded during launch and unfolded after entering orbit is a key technology and an effective means to solve the space requirement of the hood. [0003] Existing expandable shades mainly include mechanism-expandable, inflatable-...
