[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model embodiment provides a car interior headliner module that can be quickly disassembled and replaced, such as... Figures 1-5 As shown: Includes an inner roof trim module 1 and a vehicle frame 3; the inner roof trim module 1 is installed at the bottom of the vehicle frame 3, an auxiliary structure 2 is provided at the middle position of the inner roof trim module 1 and the vehicle frame 3, and disassembly / reassembly structures 4 are provided on both sides and both ends inside the inner roof trim module 1.

[0023] The disassembly / assembly structure 4 includes a mounting hole 406, which is located inside the inner top decoration module 1. A bolt 401 is installed inside the mounting hole 406. Mounting grooves 402 are provided on both sides of the mounting hole 406. A spring 403 is installed inside the mounting grooves 402. A plug 404 is installed on one side of the spring 403. Slots 405 are provided on both sides of one end of the bolt 401. External threads are provided on the outer side of the bolt 401. Internal threads are provided inside the mounting hole 406. The bolt 401 and the mounting hole 406 form a threaded connection. The two ends of the spring 403 are fixed to one side of the mounting groove 402 and one side of the plug 404, respectively. The spring 403 and the plug 404 form a telescopic structure. Two sets of bolts 401 are provided, and the two sets of bolts 401 are symmetrically distributed on both sides and both ends inside the inner top decoration module 1.

[0024] In a further preferred embodiment of this utility model, such as Figures 2-5As shown: When installing the inner top decorative module 1, the bolt 401 is inserted through the interior of the inner top decorative module 1 into the mounting hole 406.
