Description

Technical Field

[0001] This application relates to the field of automotive trim assembly technology, and in particular to a trim fixing claw and a bright trim assembly. Background Technology

[0002] Trim fixing clips are devices used to secure upper and lower trim strips and trim edging products for corner windows. Trim fixing clips typically use adhesive to attach an adhesive board to the trim strip's mounting surface, and then the clips secure the edging strip. Traditional flat adhesive boards have a pull-out force of only 60N to 150N, which is insufficient for process requirements. Therefore, protrusions are often added to the adhesive board surface to increase the bonding area. However, this structure leads to stress concentration at the bonding point between the trim strip and the protrusion, causing deformation of the trim strip's appearance and resulting in noticeable refraction. Furthermore, the protrusions can easily cause light leakage between the trim strip and the adhesive board. Utility Model Content

[0003] The technical problem to be solved by this application is to provide a trim fixing claw and a bright trim assembly that, while ensuring the pull-out force between the trim fixing claw and the trim, reduces damage to the appearance of the trim.

[0004] To solve the above-mentioned technical problems, the present application adopts a technical solution as follows: a decorative part fixing claw, including an adhesive plate for pasting on the trim assembly surface, wherein at least one glue groove is uniformly provided on the surface of the adhesive plate, and the total area of ​​the glue groove opening accounts for 10% to 35% of the total area of ​​the adhesive plate surface.

[0005] Furthermore, the adhesive groove is a long, narrow groove and / or a dotted pit.

[0006] Furthermore, the width of the opening of the glue tank is smaller than the width of the bottom of the glue tank.

[0007] Furthermore, the groove width of the glue tank is 0.5mm to 0.8mm.

[0008] Furthermore, the included angle between the sidewall of the glue tank and the bottom of the glue tank is 90° to 100°.

[0009] Furthermore, the distance between adjacent glue grooves is 1mm to 2mm.

[0010] Furthermore, the depth of the adhesive groove is 0.1 mm to 0.15 mm.

[0011] Furthermore, the adhesive plate is provided with claws, which are used to fix the edge strip to the trim strip.

[0012] Furthermore, the claw is H-shaped.

[0013] To solve the above-mentioned technical problems, another technical solution adopted in this application is: a bright trim assembly, including a trim, an edging strip, and a trim fixing claw for fixing the edging strip to the trim assembly surface, wherein the trim fixing claw is the trim fixing claw described in the above technical solution, and the adhesive plate is pasted on the trim assembly surface.

[0014] The beneficial effects of this application are as follows: Adhesive grooves are evenly distributed on the surface of the bonding board, allowing the adhesive to penetrate during the bonding process, thereby effectively increasing the contact area between the adhesive and the bonding board, and thus improving the pull-out force between the bonding board and the trim strip. Simultaneously, by controlling the area of ​​the adhesive grooves to 10% to 35% of the total surface area of ​​the bonding board, the processing amount of the bonding board is reduced while meeting the pull-out force requirements.

[0016] To explain the technical content, objectives, and effects of this application in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] During the bonding process between the decorative component fixing claw and the decorative strip 4, glue is applied to the bonding plate 1 of the decorative component fixing claw, and then bonded to the assembly surface of the decorative strip 4. However, the pull-out force of the traditional flat bonding plate is only 165N to 180N, which cannot meet the process requirements. In this embodiment, glue grooves 2 are evenly arranged on the surface of the bonding plate 1 so that the glue can penetrate into them during the bonding process, thereby effectively increasing the contact area between the glue and the bonding plate 1 and improving the pull-out force between the bonding plate 1 and the decorative strip 4.

[0018] Please refer to Figures 3 to 5 As shown, this application provides a trim fixing claw, which includes an adhesive plate 1 for attaching to the mounting surface of the trim strip 4. At least one glue groove 2 is uniformly provided on the surface of the adhesive plate 1, and the total area of ​​the opening of the glue groove 2 accounts for 10% to 35% of the total area of ​​the surface of the adhesive plate 1.

[0019] Working principle: Adhesive grooves 2 are evenly arranged on the surface of the bonding board 1, allowing the adhesive to penetrate into them during the bonding process. This effectively increases the contact area between the adhesive and the bonding board 1, thereby improving the pull-out force between the bonding board 1 and the trim 4. Simultaneously, since there is an upper limit to the pull-out force between the adhesive and the mating surface of the trim 4, the area of ​​the adhesive grooves 2 is controlled to be between 10% and 35% of the total surface area of ​​the bonding board 1. This reduces the amount of processing required for the bonding board 1 while still meeting the pull-out force requirements.

[0020] In one or more embodiments, the area of ​​the adhesive groove 2 as a percentage of the total area of ​​the adhesive board 1 can be in the range of 10%-15%, 15%-20%, 20%-25%, 25%-30%, 30%-35%, or in the range of 10%-12%, 12%-15%, 15%-18%, 18%-22%, 22%-25%, 25%-28%, 28%-32%, 32%-35%, or in the range of 10%-13%, 13%-17%, 17%-21%, 21%-25%, 25%-29%, 29%-33%, 33%-35%.

[0021] In some implementations, please refer to Figure 3 As shown, the adhesive groove 2 is a long, narrow groove. The adhesive groove 2 is positioned on the adhesive plate 1 along its length and / or width. Please refer to... Figure 7 As shown, the stress distribution of the adhesive plate 1 with the long groove and the trim 4 is more uniform and dispersed than that of the adhesive plate 1 with the protrusion 6, which can reduce the deformation of the trim surface.

[0022] In some implementations, please refer to Figure 4As shown, the glue groove 2 consists of dot-shaped pits. These dot-shaped pits can be rectangular, pyramidal, cylindrical, hemispherical, or frustum-shaped. Please refer to... Figure 8 As shown, the stress distribution of the adhesive plate 1 with dotted pits bonded to the trim 4 is more uniform and dispersed than that of the adhesive plate 1 with protrusions 6, which can reduce the deformation of the trim surface.

[0023] In some implementations, please refer to Figure 5 As shown, the adhesive groove 2 is divided into elongated grooves or dot-shaped pits. The elongated grooves are provided on the adhesive plate 1 along the length and / or width direction. The dot-shaped pits can be rectangular, pyramidal, cylindrical, hemispherical, or frustum-shaped.

[0024] In some implementations, please refer to Figure 6 As shown, the width of the groove opening of the glue tank 2 is smaller than the width of the bottom of the glue tank 2. After the glue solidifies and shrinks, it can pull the adhesive plate 1 diagonally and tighten it, and can increase the contact area of ​​the glue in the glue tank 2, so as to improve the pull-out force between the adhesive plate 1 and the trim 4.

[0025] In some implementations, please refer to Figure 6 As shown, the groove width of the glue tank 2 is A, which is 0.5mm to 0.8mm, including but not limited to 0.5mm, 0.6mm, 0.7mm and 0.8mm.

[0026] In some implementations, please refer to Figure 6 As shown, the included angle between the side wall of the glue tank 2 and the bottom of the glue tank 2 is B, which is 90° to 100°, including but not limited to 90°, 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99°, and 100°.

[0027] In some implementations, please refer to Figure 3 or Figure 4 As shown, the distance between adjacent glue tanks 2 is C, where C is 1mm to 2mm, and C includes, but is not limited to, 1mm, 1.5mm, and 2mm.

[0028] Regardless of the size of the adhesive board, once the appropriate spacing C is determined, the adhesive grooves are uniformly replicated and arranged based on this spacing C. Specifically, for small-sized adhesive boards, the adhesive groove array constructed based on the spacing C can form an adhesive groove distribution structure conforming to preset specifications on the limited surface of the board. For medium-sized or large-sized adhesive boards, simply using the same spacing C as a reference and continuously replicating the preset adhesive groove units can form a complete adhesive groove array covering the surface of the adhesive board with uniform spacing between adjacent grooves. Through the above-mentioned "fixed spacing + repeated replication" adhesive groove arrangement method, not only can the assembly requirements of adhesive boards of different sizes be effectively adapted, but the consistency and reliability of the adhesive groove distribution on the surface of all sizes of adhesive boards can also be ensured, thereby guaranteeing the stability and standardization of subsequent bonding operations.

[0029] In some implementations, please refer to Figure 6 As shown, the groove depth of the glue tank 2 is D, which is 0.1mm to 0.15mm, including but not limited to 0.1mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm, and 0.15mm.

[0030] In some implementations, please refer to Figure 9 and Figure 10 As shown, the adhesive plate 1 is provided with claws 3, which are used to fix the edging strip 5 to the trim strip 4. After the adhesive plate 1 and the trim strip 4 are fixedly connected, the claws 3 are bent so that the trim fixing claws can fix the edging strip 5 to the trim strip 4.

[0031] It is worth noting that the chuck 3 is I-shaped, which makes it easy to bend.

[0032] In some implementations, refer to Figure 3 The edge of the adhesive plate 1 has a notch, and the claw 3 is connected to the notch. In one embodiment, the claw 3 is connected to the long side of the notch. The claw 3 is assembled within the notch, and when force is applied, the adhesive around it generates a reaction force. Compared with the structure without a notch and where the claw is directly connected to the long side of the adhesive plate, this application changes the detachment method of the claw 3 from "tearing off the adhesive" to "pulling off the adhesive," requiring greater external force to detach the claw 3 from the adhesive plate 1, effectively optimizing the connection reliability of the claw 3.

[0033] Please refer to Figure 9 and Figure 10 As shown, a bright trim assembly of this application includes a trim 4, an edging strip 5, and trim fixing claws for fixing the edging strip 5 to the mounting surface of the trim 4. The trim fixing claws are the trim fixing claws in the above-mentioned technical solution, and the adhesive plate 1 is pasted on the mounting surface of the trim 4.

[0034] Working principle: During the bonding process between the fixing claw of the trim piece and the trim strip 4, glue is applied to the bonding plate 1 and then bonded to the assembly surface of the trim strip 4. Glue grooves 2 are evenly arranged on the surface of the bonding plate 1, allowing the glue to penetrate during bonding, thereby effectively increasing the contact area between the glue and the bonding plate 1 and improving the pull-out force between the bonding plate 1 and the trim strip 4.

[0035] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent modifications made based on the content of this application's specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this application.
