The application provides a hot riveting fixing structure for a cover plate of a low-thickness CCS assembly. A rivet hot fixed knot constructs for low thickness CCS subassembly apron includes support, apron, a plurality of busbar and a plurality of pencil, and the support has the wire end, and a plurality of busbars set gradually along the length direction of support, and each busbar is connected with at least one pencil, and the first end and the busbar of pencil are connected, and wherein, along the length direction of support, the second end of pencil extends to the wire end at least, and the apron covers at least and locates the wire end, apron and pencil butt to make a plurality of pencil tiling in the wire end. The hot riveting fixing structure for the cover plate of the low-thickness CCS component enables the wire harnesses to be kept in a flat state, prevents a plurality of wire harnesses from being stacked together, can effectively reduce the thickness or the height of the wire harnesses at the wire outlet end, further reduces the thickness at the wire outlet end of the bracket, and is beneficial to the lightweight design of the CCS component due to the fact that the overall thickness of the CCS component is reduced.
