Description

Technical Field

[0001] This utility model relates to a fixing device for automotive exterior parts, belonging to the field of automotive exterior fixing tools. Background Technology

[0002] Currently, the window sealing strips of some car doors are not integrally formed. They are generally divided into window rubber strips and inner and outer water cutters. Near the corner of the door, at the junction of the window rubber strip and the outer water cutter, a triangular plate is usually installed for aesthetic purposes. This triangular plate is usually a plastic part, which is fixed to the door sheet metal by its own buckle or claw structure.

[0003] Typically, the sheet metal area / space of the car door where the outer triangle plate is installed is generally small. The commonly used "D-type clip" requires a large sheet metal installation space. Unless specially designed, most vehicles cannot meet this requirement. Moreover, the "D-type clip" will be damaged after being disassembled a maximum of three times, resulting in a decrease in clamping strength. Some models use metal "barbed clips" for fixing. These clips are very secure, but once disassembled, they will deform and are difficult to reuse.

[0004] Therefore, there is a need for an automotive exterior part fixing device that can facilitate the connection between the triangular plastic part and the door sheet metal, and can facilitate loading, unloading and recycling of the clips. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a fixing device for automotive exterior parts, which facilitates the connection between the triangular plastic part and the door sheet metal, and facilitates the installation, removal and recycling of the buckle; it can overcome the shortcomings of the prior art.

[0006] The objective of this utility model is achieved through the following technical solution: This utility model discloses an automotive exterior trim fixing device, which is used to install exterior trim onto the vehicle body sheet metal, and includes: Plastic buckle, the plastic buckle is columnar, with a groove at one end of the plastic buckle, and a mounting post on the outer trim piece that engages with the groove; A clamping spring is provided, which is located in the slot and between the mounting post and the inner wall of the slot; Mounting holes are located on the body sheet metal. The end of the plastic clip away from the slot engages with the mounting hole. The outer wall of the plastic clip has a claw that can deform and reset to clamp the body sheet metal.

[0007] The aforementioned card slot and mounting post are square structures.

[0008] The aforementioned locking spring has an outward-facing "U"-shaped structure.

[0009] As mentioned above, a limiting ring is provided on the outer wall of the plastic buckle end near the card slot.

[0010] As mentioned above, one end of the claw is connected to a plastic buckle, and the other end is tilted outward. There is a gap between the free end of the claw and the limiting ring for the body sheet metal.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model facilitates the connection between the plastic clip and the exterior trim by using a mounting post and a slot. The plastic clip is secured by an interference fit between a clamping spring and the exterior trim, making it easy to disassemble and ideal for applications requiring frequent disassembly. The other end of the plastic clip, furthest from the exterior trim installation end, is engaged with the vehicle body sheet metal, and the clips provide a limiting position, thus completing the installation of the exterior trim. The inward retraction of the clips also facilitates disassembly and recycling of the plastic clip.

[0012] 2. A limiting ring is provided on the outer wall of one end of the plastic buckle near the slot. One end of the claw is connected to the plastic buckle, and the other end is tilted outward. There is a gap for the body sheet metal between the free end of the claw and the limiting ring. The limiting ring and the free end of the claw can limit and position the body sheet metal after it is installed.

[0013] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0022] like Figures 1-6 As shown, this utility model discloses an automotive exterior trim fixing device for mounting an exterior trim 1 onto a vehicle body sheet metal 2. It includes a plastic clip 3, a clamping spring 6, and a mounting hole 7. Specifically, the plastic clip 3 is cylindrical, with a groove 4 at one end. The exterior trim 1 has a mounting post 5 that engages with the groove 4. The groove 4 and mounting post 5 are square structures. The clamping spring 6 is located within the groove 4 and between the mounting post 5 and the inner wall of the groove 4. The clamping spring 6 has an outward-opening "U"-shaped structure. The mounting hole 7 is located on the vehicle body sheet metal 2. The end of the plastic clip 3 away from the groove 4 engages with the mounting hole 7. A deformable, repositionable claw 8 for clamping the vehicle body sheet metal 2 is provided on the outer wall of the plastic clip 3. Two symmetrically arranged clips 8 have an outer diameter slightly larger than the mounting holes on the body sheet metal 2. When the plastic clip 3 is pushed in, it deforms due to compression and passes smoothly through the mounting holes 7. After being pushed in continuously, the clip 8 returns to its original shape on the body sheet metal 2. This structure, with the mounting post 5 engaging with the slot 4, facilitates the connection between the plastic clip 3 and the exterior trim 1. At the same time, the plastic clip 3 is secured by the clamping spring 6 and the exterior trim 1 through an interference fit, making it easy to disassemble the exterior trim 1. It is very suitable for occasions where frequent disassembly is required. The other end of the plastic clip 3, away from the mounting end of the exterior trim 1, is engaged with the body sheet metal 2, and the clip 8 completes the positioning, thus completing the installation of the exterior trim 1. This device also facilitates disassembly through the inward retraction of the clip 8, making it easy to recycle the plastic clip 3.

[0023] Furthermore, a limiting ring 9 is provided on the outer wall of one end of the plastic buckle 3 near the slot 4. One end of the claw 8 is connected to the plastic buckle 3, and the other end is tilted outward. A slot 10 for the body sheet metal 2 is provided between the free end of the claw 8 and the limiting ring 9. With this structure, the body sheet metal 2 can be limited and positioned after installation through the limiting ring 9 and the free end of the claw 8.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to restrict the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present utility model and based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
