Description

Technical Field

[0001] This application relates to the technical field of trim connection structures, and particularly to a metal buckle for an automotive trim pillar. Background Art

[0002] Automotive side pillars are usually formed by stamping metal materials, and there may be many grooves and through-hole structures for laying pipelines reserved on them. These irregular structures will affect the aesthetics of the vehicle body. Therefore, a trim structure is usually configured outside the automotive side pillar and directly fixed and connected using curing glue. Although it is stable, it is not convenient for later disassembly, assembly, and maintenance. Summary of the Invention

[0003] The purpose of this application is to provide a metal buckle for an automotive trim pillar that is firmly connected and convenient for disassembly and assembly.

[0004] To achieve the above purpose, this application provides a metal buckle for an automotive trim pillar: including a supporting part and a clamping part. The supporting part includes a fitting plate adapted to be embedded in the trim of the automotive side pillar. On the side of the fitting plate facing the trim of the automotive side pillar, a shaft body is fixedly connected. The clamping part includes a bridging block, and the bridging block is fixedly connected to the end of the shaft body. At the end of the bridging block facing away from the shaft body, there is an inner embedded cone, and the outer side surface of the inner embedded cone has a limiting plate adapted to be embedded into the automotive side pillar. A deformation groove is formed between the limiting plate and the inner embedded cone. On the side of the limiting plate facing the shaft body, there is a dial plate that can cause elastic deformation of the limiting plate.

[0005] As a preference, there is also a retaining handle between the shaft body and the bridging block. The cross-section of the retaining handle is larger than that of the bridging block, and the retaining handle is used to fit against the outer wall of the automotive side pillar.

[0006] As a preference, the top of the dial plate has a pressure-bearing handle, and a relief groove is provided on the side surface of the retaining handle, adapted to accommodate the pressure-bearing handle and reserve enough space for the movement of the pressure-bearing handle.

[0007] As a preference, there are two limiting plates, and the two limiting plates are located on the symmetric sides of the inner embedded cone. Symmetric arrangement is more convenient for bearing force.

[0008] As a preference, there are also two sets of combinations of the dial plate and the pressure-bearing handle, and there are also two corresponding relief grooves provided on the retaining handle for fitting with two symmetric pressure-bearing handles.

[0009] As a preference, friction strips are provided on the outer sides of the two pressure-bearing handles facing away from each other to enhance the contact friction between the fingers and the pressure-bearing handles.

[0010] As a preference, the fitting plate is arc-shaped, which has an inner arc surface and an outer arc surface. The shaft body is located on the outer arc surface of the fitting plate, thus pointing to the vehicle side pillar.

[0011] As a preference, the supporting part and the engaging part are connected together by secondary hot melting; the fitting plate has a load-reducing groove penetrating the inner and outer arc surfaces, and the embedded cone has a deformation channel penetrating both ends, making the embedded cone more likely to undergo adaptive deformation.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows:

[0013] (1) By designing the supporting part and the engaging part, which are respectively matched with the side pillar trim and the vehicle side pillar, the side pillar trim can be stably connected to the vehicle side pillar without using curing glue, and the metal buckle is convenient for disassembly and assembly, providing convenience for subsequent vehicle maintenance and repair;

[0014] (2) By designing the radian of the fitting plate, it can better fit with the side pillar trim, better restrain the side pillar trim, and keep good stability after the trim is installed on the vehicle side pillar. Description of the Drawings

[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence.

[0025] The terms "comprising" and "having" in the description and claims of the present application, as well as any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0026] As Figure 1-6 shown in the automotive trim pillar metal buckle, it includes a supporting portion 1 and an engaging portion 2 made of metal material. After the supporting portion 1 and the engaging portion 2 are respectively formed, the two are then connected together by a secondary hot melting method. Although this is cumbersome, it can reduce the manufacturing difficulty. The supporting portion 1 includes an arc-shaped fitting plate 101 for embedding into the trim panel of the automotive side pillar. On the side of the fitting plate 101 facing the automotive side pillar trim panel, a cylindrical shaft body 103 is fixedly connected. The fitting plate 101 has an arc-shaped inner side and an outer side. The shaft body 103 is located on the arc-shaped outer side of the fitting plate 101. The part of the fitting plate 101 outside the end of the shaft body 103 has a load-reducing groove 102 that penetrates the inner and outer arc-shaped sides, reducing consumables and self-weight while ensuring structural strength to pursue better lightweight.

[0027] The specific structure of the engaging part 2 includes a bridging block 201. The bridging block 201 is fixedly connected to the end of the shaft body 103. The end of the shaft body 103 facing away from the fitting plate 101 is located at the center of the bridging block 201. There is also a disc-shaped retaining handle 104 between the shaft body 103 and the bridging block 201. The cross-section of the retaining handle 104 is larger than that of the bridging block 201, and it can closely adhere to the surface of the vehicle side pillar.

[0028] One end of the bridging block 201 facing away from the shaft body 103 has an embedded cone 202, which will be completely embedded in the vehicle side pillar after installation. The embedded cone 202 has a deformation channel 207 running through both ends, that is to say, the embedded cone 202 is not solid and can undergo adaptive deformation during disassembly and assembly. The outer side surface of the embedded cone 202 has a limiting plate 203. There are two limiting plates 203, and the two limiting plates 203 are located on the symmetrical sides of the embedded cone 202 and are significantly wider than the embedded cone 202. Since the limiting plate 203 has elasticity, it can be embedded into the vehicle side pillar with a slightly smaller insertion diameter. A deformation groove 204 is formed between the limiting plate 203 and the embedded cone 202 to facilitate the warping deformation of the limiting plate 203. The side surface of the limiting plate 203 facing the shaft body 103 has a dial plate 205. Compared with the limiting plate 203, the deformation ability of the dial plate 205 is much worse. The dial plate 205 is used to drive the limiting plate 203 to deform. The top of the dial plate 205 has a pressure-bearing handle 206, which is the part that can be pressed by a finger. A relief groove 105 is formed on the side surface of the retaining handle 104 to accommodate the pressure-bearing handle 206, and the relief groove 105 is significantly larger than the thickness of the pressure-bearing handle 206, providing sufficient internal pressure space for the pressure-bearing handle 206. There are also two sets of combinations of the dial plate 205 and the pressure-bearing handle 206, corresponding to the two limiting plates 203. There are also two relief grooves 105 formed on the retaining handle 104, respectively accommodating the two pressure-bearing handles 206. Friction strips 208 are provided on the outer side surfaces of the two pressure-bearing handles 206 facing away from each other to increase the contact friction with the finger pulp.

[0029] Working principle: When using this metal buckle, it is necessary to open an insertion opening on the vehicle side pillar and a long hole slightly wider than the fitting plate 101 on the side pillar trim. The extending direction of the long hole is roughly the same as the length direction of the side pillar trim. During installation, first let the fitting plate 101 pass through the long hole of the side pillar trim, and then rotate it by 90°. The arc surface on the outer side of the fitting plate 101 just fits the inner wall of the side pillar trim. Then, press the pressure-bearing handle 206 with two fingers to make the two limiting plates 203 warp, and the side spacing between the two limiting plates 203 decreases, so that the embedded cone 202 can be pressed into the insertion opening opened on the vehicle side pillar. After releasing the pressure-bearing handle 206, the two limiting plates 203 can abut against the inner wall of the vehicle side pillar, the dial plate 205 fits the inner wall of the insertion opening, and the retaining handle 104 fits the outer arm of the vehicle side pillar. Thus, the side pillar trim can be stably connected to the vehicle side pillar, and can well wrap the pipeline structure arranged on the vehicle side pillar, making the vehicle side pillar more regular and beautiful.
