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...
