Description

Clips for fixing car trim

The present disclosure relates to a clip for fixing a trim of a vehicle.

In general, a trim member as a decorative part for improving external beauty is attached to various parts of the interior of a vehicle.

For example, the side structure of an automobile includes a rear side structure, a center side structure, and a front side structure. The C-pillar or rear pillar constitutes the rear side structure. A B-pillar or central pillar is positioned between the rear door glass and the front door glass to form a central side structure. An A-pillar or front pillar is positioned between the front door glass and the windshield glass to form a front side structure. Inside the pillar portion, each pillar trim as a decorative portion is mounted.

In addition, a rear package tray is provided behind the rear seat of the vehicle. Two speakers are mounted on both sides of the rear package tray, respectively. The rear package trim is attached between the two speakers, providing space for air fresheners and other simple items.

In addition, the door of a vehicle is composed of an exterior panel, an interior panel, and a door trim. Attached to the door trim are an armrest on which an occupant can place his/her arm, and a pocket capable of accommodating objects such as books that are thin in volume. Further, above the armrest, a door unlocking device and an auxiliary handle formed of grooves are mounted.

This trim is coupled to and fixed to an interior panel of the vehicle body (eg, a crash panel or an instrument panel). To secure the trim to the inner panel, clips or fasteners are used.

In the conventional clip for fixing the trim, the clip is formed thick so that the fastening part inserted into the insertion hole of the trim maintains a shape protruding outward while being elastically deformed. In addition, the insertion hole of the trim should be formed to have an inner diameter through which the fastening part can be smoothly inserted into the insertion hole.

Therefore, in the conventional clip for fixing the trim, the size of the insertion hole of the trim is determined according to the thickness of the clip. Accordingly, the degree of freedom of design is reduced when designing and manufacturing automobiles.

In addition, in the conventional clip for fixing the trim, the fastening portion of the clip inserted into the insertion hole of the trim maintains the state in which the trim is fixed to the instrument panel only by its own elastic force. Accordingly, the trim may be easily separated from the instrument panel due to impact generated during driving of the vehicle, resulting in high maintenance costs.

One embodiment of the present disclosure provides a clip for fixing a trim of a vehicle in the form of a leaf spring, in which the trim is fixed and coupled to an instrument panel. In addition, one embodiment of the present disclosure provides a clip for fixing a trim of a vehicle that solves design restrictions due to the thickness of the clip.

It is moved and retracted to the engaging hole 310 of the boss 300 by deformation. That is, due to the contact between the mating object hooking part 230 and the insertion hole 110, each elastically deformable part is elastically deformed to bend to the hooking hole 310. For example, the object-catching portion 230 of the first elastically deformable portion 210 may be elastically deformed downward, and the object-catching portion 230 of the second elastically deformable portion 220 may be elastically deformed upward. there is. The trim 100 is continuously transferred toward the instrument panel 400 . After the trim 100 is moved toward the instrument panel 400 so that the other surface 122 of the trim 100 comes into contact with the rear surface of the stopper 260 (or, the mating part 230 of the trim 100 After the trim 100 is transported enough to deviate from the insertion hole 110), the mating object catching part 230 returns to its original state by the elastic force of the elastic deformation part, and the outer surface of the mating object catching part 230 (front The surface 231 may be in contact with or caught on the one surface 121 of the trim 100 . Accordingly, the trim 100 may be assembled to be fixed to the instrument panel 400 through the clip 200 .

Therefore, when the trim 100 is coupled to the instrument panel 400 using the clip 200, the insertion hole 110 of the trim 100 does not need to be expanded, and the degree of freedom in design when designing a vehicle is improved. In addition, the trim 100 is maintained coupled to the instrument panel 400 by the clip 200 . Therefore, even when an impact load is applied to the instrument panel 400 due to an impact generated during driving of the vehicle, the trim 100 is not separated from the instrument panel 400 .
