Abstract

The invention provides an electric control box structure for a space vehicle and an assembly method thereof. The structure comprises a base and a steamer machine case, wherein the steamer machine casecomprises an upper layer steamer machine case and lower layer steamer machine case; the base comprises a bottom plate and a side plate; the side plate is arranged around the bottom plate so as to form a splicing structure; an electronic element and PCBs are arranged in the splicing structure; a horizontal framework structure is arranged inside the splicing structure; the horizontal framework structure is used for installing the electronic device and the PCBs; the lower layer steamer machine case is arranged on the splicing structure in the horizontal direction; the upper layer steamer machinecase is arranged on the lower layer steamer machine case in the horizontal direction; the PCBs are respectively arranged in the lower layer steamer machine case and the upper layer steamer machine case. By using the scheme, the space utilization rate of the existing electric control box installation and design structure can be improved, so that the problem of space waste inside the machine case is solved. By using the technical scheme provided by the invention, the structure is compact and reasonable; the assembly and the dismounting are convenient; the shielding performance is good; the costis relatively low.

Description

technical field [0001] The invention belongs to the technical field of structure and assembly of an electric control box for a spacecraft, and in particular relates to a structure and an assembly method for an electric control box for a spacecraft. Background technique [0002] The lightweight design requirements of the existing spacecraft electric control box for spacecraft are getting higher and higher, which makes the internal space design requirements high or the internal space utilization rate is low; and the spacecraft electric control box needs to undergo strict mechanical environment simulation tests. The structural rigidity design of the electrical control box for aircraft has high requirements, especially the rigidity of the PCB installation structure inside the electrical control box. If the structural stiffness design of the electrical control box for spacecraft is insufficient, it will seriously damage the use of electronic components. In severe cases, the compon...
