[0002] The car headliner plays a number of key roles within the vehicle. Its primary function is to provide a top structure to the interior, enhancing the rigidity and stability of the vehicle body, especially in convertibles or sunroof models, where it helps maintain the shape and strength of the roof. In the event of a rollover, the headliner can provide some protection from injury to the occupants. The color and material of the headliner coordinate with the interior décor, enhance the visual effect of the interior, and sometimes there are lighting elements, such as reading lights or mood lights.

[0003] The processing technology of automobile roof generally includes molding process, cold foaming process, molding process, riveting fixation, and composite process (combining different materials, such as fabrics, non-woven fabrics, foams, etc., to achieve heat insulation, sound insulation and decorative effects). Among them, when the existing automobile roof is riveted, only the four corners of the automobile roof are positioned. During the riveting process, the automobile roof is prone to offset, which causes the rivets to be misplaced, resulting in the need for sheet metal reset or recycling of the automobile roof, which requires high material consumption and high cost.

[0044] In summary, this application has the following beneficial effects:

[0045] 1. Multiple groups of first positioning components are distributed around the circumference of the ceiling to position it and limit the slippage of the ceiling. The second positioning components are further inserted into the ceiling body without additional clamping. This can cope with the wear of the ceiling surface or the displacement of the ceiling during the clamping of the four corners of the ceiling by the clamping mechanism, thereby solving the problem of ceiling displacement and misalignment of rivets, which leads to the need for sheet metal reset or recycling of the car roof, high consumables and high costs.

[0046] 2. The first positioning body performs surrounding support and positioning for the ceiling, and the first positioning body is elastic, which can not only provide good support and positioning, but also buffer the impact force of riveting generated by a part of the riveting components when riveting the ceiling, and can also protect the surface of the ceiling, protect its surface integrity, and provide appearance quality.
