Embodiment Construction

[0028] Such as figure 1 As shown, a passenger car roof interior assembly structure includes a roof frame 1 for support and a soft cladding 4 for decoration on the exposed surface of the roof, and the roof frame 1 is connected by a plurality of self-tapping screws 2 There is one layer of five-plywood 3, and the soft cladding 4 is connected to the outer surface of the five-plywood 3 by adhesive glue 5.

[0029] Putty putty 6 is filled in the gap between two adjacent five-plyboards 3 , and the height of the exposed surface of the putty putty 6 is flush with the outer surface of the five-plywood board 3 . The self-tapping screw 2 adopts a cross countersunk head self-tapping screw. After the self-tapping screw 2 is connected in place, the countersunk hole on the five-ply plate 3 and the head of the self-tapping screw 2 are filled and smoothed by putty 6 to ensure adhesion. Flatness of the interface.

[0030] The adhesive glue 5 adopts SX-001 adhesive, and the SX-001 adhesive is s...

Abstract

The invention discloses a passenger car roof interior trim assembly structure. The structure comprises a top cover framework used for supporting and a soft wrapping layer used for decoration on an exposed face of a car roof, the top cover framework is connected with a layer of five-ply board through a plurality of self-tapping screws, and the soft wrapping layer is connected to the outer surface of the five-ply board through adhesive glue. An assembly technological process comprises the seven steps of: five-ply board assembly, putty coating and scraping, putty polishing, bottom plate cleaning, bonding glue spraying, soft wrapping layer bonding, and finishing. The structure is simple and reasonable and effectively guarantees the connecting strength and the appearance attractiveness, the assembly process is easy to achieve, the technology method universality is high, the input material cost is low, the operation skill requirement is low, the assembly line production mode can be met, the overall assembly quality is improved, the clout nails are not exposed, the appearance is better, and the problems of exposure and collapse of soft leather screws of luxury passenger cars are effectively solved.

Description

technical field [0001] The invention relates to the field of passenger car roof trim structures, in particular to a passenger car roof trim assembly structure and a process thereof. Background technique [0002] At present, soft leather is used as the roof decoration material of overseas passenger cars. The assembly process uses polyurethane adhesive to bond the diamond-shaped soft leather assembly to the top frame. The problem is that the top frame needs to be designed with too many bonding webs. Moreover, the installation process is complicated, and there will be risks of non-sticking and falling off of the leather in the long run. Contents of the invention [0003] The purpose of the present invention is to provide an assembly structure for the roof trim of a passenger car, which solves the problems of the prior art that the installation process is complicated, and the leather does not stick and fall off after long-term use. [0004] In order to solve the problems of t...
