Description

Technical Field

[0001] This utility model belongs to the field of automotive interior structure technology, and in particular relates to an anti-detachment structure for automotive interior roof. Background Technology

[0002] In the automotive technology field, the headliner is an important component of the overall vehicle interior. Its main function is to enhance the decorative appeal of the vehicle's interior. Simultaneously, the headliner improves heat insulation from the outside environment, reduces interior noise, enhances sound absorption, and improves passenger comfort and safety. However, after a certain period of use, the non-woven fabric layer of current headliners often tends to peel off, hindering their stable use. A search revealed patent application number 202320087129.5, which discloses an automotive headliner structure belonging to the field of automotive interior structure technology. The headliner body includes a polyurethane headliner substrate, a cotton layer, and a non-woven fabric layer. Two sets of symmetrical mounting seats are fixedly embedded on the front of the headliner body, each with internal threads on its inner wall. A set of pressure strips is located at the rear of the headliner body, with two T-shaped mounting holes on the back of each pressure strip.

[0003] However, in actual use, the applicant found that while the non-woven fabric layer is prevented from falling off by fixing the pressure strip, the pressure strip requires personnel to install multiple mounting screws using installation tools and to cover the screws with caps, which is not convenient. Therefore, we propose an anti-fall-off structure for automotive interior headliners. Utility Model Content

The cotton layer 12 is fixedly disposed at the bottom of the polyurethane headliner substrate 11, and the non-woven fabric layer 13 is fixedly disposed at the bottom of the cotton layer 12. A snap-button 6 is fixedly embedded at the bottom of the interior headliner body 1, and the snap-button 6 is fixedly connected to the polyurethane headliner substrate 11. Several snap-buttons 6 are provided at the bottom of the interior headliner body 1. The bottom of the headliner body 1 is fixedly connected to an anti-detachment clamping ring 4, and the top of the anti-detachment clamping ring 4 is fixedly provided with a male snap fastener 41. Several male snap fasteners 41 are provided on the top of the anti-detachment clamping ring 4, and the male snap fasteners 41 and female snap fasteners 6 are connected in cooperation. The male snap fasteners 41 and female snap fasteners 6 are existing technology and will not be described in detail here. The top of the anti-detachment clamping ring 4 abuts against the bottom of the headliner body 1. By snapping the male snap fasteners 41 on the top of the anti-detachment clamping ring 4 into the corresponding snap fasteners, the problem is solved. In the female snap 6, the anti-detachment clamping ring 4 can be fixed to the bottom of the interior headliner body 1, and the top of the anti-detachment clamping ring 4 abuts against the non-woven fabric layer 13 at the bottom of the interior headliner body 1, thereby preventing the non-woven fabric layer 13 at the bottom of the headliner from falling off. Furthermore, through the cooperation of the male snap 41 and the female snap 6, it is easy for personnel to install and fix the anti-detachment clamping ring 4 to the bottom of the interior headliner body 1. The bottom of the interior headliner body 1 is fixedly embedded with a sunroof frame 2 and a light fixture 3. The sunroof frame 2 is equipped with... The electric sunroof and the lighting installed on the lamp holder 3 are electrically connected to the vehicle power supply through connecting wires. When installing and fixing the anti-drop clamping ring 4, the male snap 41 on the top of the anti-drop clamping ring 4 can be aligned one by one and snapped into the female snap 6 at the corresponding position at the bottom of the interior headliner body 1.
