A solar cell module fixing structure and fixing method of a string-type semi-rigid plate

Abstract

The invention, which belongs to the technical field of the spacecraft power supply, discloses a solar cell module fixation structure of a string-tightening type semi-rigid board and a fixation method thereof. The fixation structure comprises a string-tightening type semi-rigid substrate and a solar cell module; and a tightened string is arranged on the string-tightening type semi-rigid substrate. The solar cell module fixation structure is characterized in that the tightened string is formed by a horizontal tightened string and a longitudinal tightened string; fixed buckles are fixed at tightened string intersection points of the horizontal tightened string and the longitudinal tightened string; cross-shaped grooves are formed in the lower surfaces of the fixed buckles; the tightened string intersection points of the horizontal tightened string and the longitudinal tightened string are fixed in the cross-shaped grooves by adhesives; and the lower surfaces of the fixed buckles are fixed on the solar cell module by adhesives. On the basis of the technical scheme, the reliability is high; the tightened string intersection points can be fixed effectively in an omnibearing mode; and firm bonding of the solar cell module and the tightened string of the string-tightening type semi-rigid substrate is realized.

Description

technical field [0001] The invention belongs to the technical field of spacecraft power supplies, and in particular relates to a solar cell module fixing structure and a fixing method of a string-type semi-rigid plate. Background technique [0002] At present, solar panels for spacecraft are divided into two types: rigid panels and semi-rigid panels, and semi-rigid substrates are further divided into grid-type and string-type. The rigid plate structure is a carbon fiber layer pasted on both sides of the aluminum honeycomb core, and a layer of polyimide film is covered on the solar cell installation surface; the grid-type semi-rigid structure is a carbon fiber frame with a flexible glass fiber grid, and the grid is relatively dense. The hole area is generally 1cm 2 ;The string-type semi-rigid structure is a carbon fiber frame with flexible strings that cross vertically, horizontally and vertically. The strings are relatively sparse, and the area of ​​the string holes is gene...

AI Technical Summary

Problems solved by technology

Due to the difference in structure, the installation method of the solar cell module and the stringed semi-rigid board cannot use the traditional rigid board process method, that is, the back surface of the solar cell is pasted on the polyimide film surface of the rigid board with an adhesive; The installation method of multi-point hooking of grid-type semi-rigid boards is not suitable for sparse string structures
