Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and in particular to an installation and removal structure for a decorative cover plate. Background Technology

[0002] Cars have become an indispensable means of transportation in daily life. With the continuous improvement of living standards, cars are no longer just simple means of transportation. When driving a car, people not only pay attention to its performance, but also increasingly pursue the quality and class of its interior. The level of refinement of the interior is one of the key factors for drivers and passengers to evaluate the quality of a car.

[0003] Automotive interior trim primarily provides mounting structures for other functional structural components while also serving a decorative and aesthetic purpose by covering internal parts. Most functional components require maintenance, necessitating that the trim covering these maintenance-dependent parts be removable, easy to disassemble, and capable of withstanding a certain number of disassemblies.

[0004] The car is equipped with a fragrance system, which requires regular fragrance replacement; therefore, the corresponding fragrance service cover needs to be removed. The existing fragrance service cover structure is as follows: Figure 1 and Figure 2 As shown. The existing fragrance repair cover structure includes a fragrance repair cover 10, an upper single-sided clip 110, a lower metal snap clip 120, a small opening 130 for disassembling the fragrance repair cover, a mounting frame 20, an upper snap-fit ​​edge 210 on the mounting frame, and a snap-fit ​​mounting hole 220 on the mounting frame. During installation, align the lower clip of the fragrance repair cover 110 with the lower snap-fit ​​edge 220 of the mounting frame, align the lower metal snap clip 120 with the snap-fit ​​mounting hole 220, and then forcefully snap the fragrance repair cover 10 onto the mounting frame 20. During disassembly, use a flathead screwdriver to forcefully remove the lower metal snap-fit ​​point from the mounting hole through the small opening 130.

[0005] As can be seen, current vehicle fragrance system service covers typically use a snap-fit ​​design with a small opening on the edge for removal. When changing the fragrance, a flathead screwdriver or pry bar is used to apply sufficient force through this opening to remove the cover. However, since fragrances in fragrance systems generally need to be replaced every three months, and with frequent use, they may need to be replaced as often as once a month. This results in a high frequency of cover removal. The existing snap-fit ​​design with the small opening means that after repeated removal and removal, the snaps may wear down, the clamping force may be insufficient, or the corresponding locking holes on the frame may be damaged, making it impossible to install the service cover. This necessitates replacing the entire service cover, or even the frame itself, increasing after-sales maintenance costs. Furthermore, the small opening on the service cover affects its overall aesthetics. Summary of the Invention
