[0002] In the modern lighting industry, especially in the manufacturing of lights with complex structures such as automotive taillights, a design solution using an integrated decorative frame that runs through the taillight is often adopted to address cost issues. However, during the actual installation of the decorative frame and the thick-walled component, the decorative frame can scratch the thick-walled component, leading to a decrease in the overall yield of the light and preventing effective cost reduction.
[0003] Chinese Patent (Publication No.: 222911420U) discloses a novel luminous thick-walled component, including a dual-color component, a headlight decorative frame, and a circuit board module. The dual-color component comprises a first dual-color thick-walled component and a second dual-color thick-walled component. The headlight decorative frame is disposed on the outer side of the second dual-color thick-walled component, and the second dual-color thick-walled component is disposed on the first dual-color thick-walled component and located within the headlight decorative frame. The circuit board module transmits light to the dual-color component via a light guide, achieving a double-layer circuit. However, when installing the headlight decorative frame and the luminous thick-walled component, the headlight decorative frame is prone to scratching the luminous thick-walled component. Utility Model Content
[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a structure for preventing scratches on decorative frames and thick-walled components, thereby reducing the risk of scratches from the decorative frame to the thick-walled component. To achieve the above objective, the technical solution adopted by this utility model is as follows: a structure for preventing scratches on decorative frames and thick-walled components, comprising an upper decorative frame, a lower decorative frame, and a thick-walled component, wherein the thick-walled component is disposed between the upper and lower decorative frames, and the upper and lower decorative frames are provided with snap-fit structures, and the back of the thick-walled component is provided with a frosted inner lining.
[0005] The buckle structure includes a limiting groove and an elastic locking plate. Both ends of one side of the upper decorative frame are connected to a first extension plate, and the limiting groove is formed on the first extension plate. Both ends of one side of the lower decorative frame are connected to a second extension plate, and the elastic locking plate is disposed on the second extension plate. The elastic locking plate is engaged into the limiting groove.
[0006] The mist generator is equipped with a fixing plate, the fixing plate has a first through groove, and the upper decorative frame has a first buckle, which engages with the first through groove.
[0007] The first buckle includes a first limiting plate, a second through groove is provided on the first limiting plate, and an elastic limiting plate is provided in the second through groove, the elastic limiting plate abutting against the fixed plate.
[0008] The elastic limiting plate has a right-angled structure.
[0009] A second limiting plate is provided on one side of the upper decorative frame, and a third limiting plate is provided on one side of the lower decorative frame. The thick-walled member has a T-shaped structure, and one end of the thick-walled member abuts against the second and third limiting plates.

[0011] The surface of the thick-walled component is provided with optical patterns.
[0012] The technical advantages of this invention are as follows: An elastic plate passes through the limiting groove. Because the elastic plate has an L-shaped structure, its end abuts against the first elongated plate. The upper and lower decorative frames are connected together. Due to the presence of the first and second elongated plates, a cavity exists between the upper and lower decorative frames, and the thick-walled component is located within this cavity. The gap between the thick-walled component and the upper decorative frame is 1mm, and the gap between the thick-walled component and the lower decorative frame is also 1mm, reducing the probability of scratching the thick-walled component. The thick-walled component is fixed between the upper and lower decorative frames by a mat against its back. By separating the upper and lower decorative frames, the risk of the thick-walled component being scratched by the decorative frames is reduced. Attached Figure Description

[0022] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.
[0023] like Figures 1-7 As shown, a structure for installing a decorative frame and a thick-walled component to prevent scratches includes an upper decorative frame 1, a lower decorative frame 2, and a thick-walled component 3. The thick-walled component 3 is disposed between the upper decorative frame 1 and the lower decorative frame 2. The upper and lower decorative frames 1 and 2 are provided with snap-fit structures 4, and the back of the thick-walled component 3 is provided with a frosting inner fitting 5. After the upper and lower decorative frames 1 and 2 are connected together by the snap-fit structures 4, they form a cavity. The thick-walled component 3 is disposed within this cavity, with a 1mm gap between the thick-walled component 3 and the upper decorative frame 1, and a 1mm gap between the thick-walled component 3 and the lower decorative frame 2, reducing the probability of scratching the thick-walled component 3. The frosting inner fitting 5 abuts against the back of the thick-walled component 3, thus fixing the thick-walled component 3 between the upper and lower decorative frames 1 and 2.
[0024] The snap-fit structure 4 includes a limiting groove 401 and an elastic locking plate 402. Both ends of one side of the upper decorative frame 1 are connected to a first extension plate 403, and the limiting groove 401 is formed on the first extension plate 403. Both ends of one side of the lower decorative frame 2 are connected to a second extension plate 404, and the elastic locking plate 402 is disposed on the second extension plate 404. The elastic locking plate 402 engages with the limiting groove 401. The first extension plate 403 is connected to both ends of one side of the upper decorative frame 1, and the second extension plate 404 is connected to both ends of one side of the lower decorative frame 2. The elastic locking plate 402 on the second extension plate 404 engages with the limiting groove 401 on the first extension plate 403. There are two elastic locking plates 402, each with an L-shaped structure. After passing through the limiting groove 401, the end of the elastic locking plate 402 abuts against the first extension plate 403 due to its L-shaped structure. The upper decorative frame 1 and the lower decorative frame 2 are connected together. Due to the presence of the first extension plate 403 and the second extension plate 404, there is a cavity between the upper decorative frame 1 and the lower decorative frame 2, and the thick-walled member 3 is located in the cavity.
[0025] The inner misting device 5 is equipped with a fixing plate 501, which has a first through groove 502. The upper decorative frame 1 has a first buckle 6, with multiple buckles 6 evenly spaced on it. The first buckles 6 engage with the first through groove 502. The inner misting device 5 abuts against the thick-walled component 3, and is engaged in the first through groove 502 by the first buckles 6 on the upper decorative frame 1. The first buckles 6 also abut against the fixing plate 501, thus fixing the inner misting device 5. The inner misting device 5 abuts against the back of the thick-walled component 3, which is then fixed between the upper decorative frame 1 and the lower decorative frame 2.
[0026] The first buckle 6 includes a first limiting plate 601, on which a second through groove 602 is formed. An elastic limiting plate 603 is disposed within the second through groove 602, and the elastic limiting plate 603 abuts against the fixing plate 501. The second through groove 602 is a square groove used to provide a setting position for the elastic limiting plate 603. During the insertion of the first limiting plate 601 into the second through groove 602, the elastic limiting plate 603 is compressed. After the first limiting plate 601 is fully inserted into the second through groove 602, the elastic limiting plate 603 pops out and abuts against the fixing plate 501, thus fixing the first buckle 6.
[0027] The elastic limiting plate 603 has a right-angled structure. During the insertion of the first limiting plate 601 into the second through slot 602, the elastic limiting plate 603 is offset to one side. After the first limiting plate 601 is fully inserted into the second through slot 602, the elastic limiting plate 603 pops out, and the right-angled edge of the elastic limiting plate 603 abuts against the fixing plate 501, and the first buckle 6 is fixed.
[0028] A second limiting plate 101 is provided on one side of the upper decorative frame 1, and a third limiting plate 201 is provided on one side of the lower decorative frame 2. The thick-walled component 3 has a T-shaped structure, with one end abutting against the second limiting plate 101 and the third limiting plate 201. The thick-walled component 3 has a T-shaped structure, with one end located between the upper decorative frame 1 and the lower decorative frame 2, and the other end located between the second limiting plate 101 and the third limiting plate 201 within the frosting inner part 5 and 2, thus fixing the thick-walled component 3. The placement of the second limiting plate 101 and the third limiting plate 201 reduces the contact area between the thick-walled component 3 and the upper and lower decorative frames 1 and 2, reducing scratches on the thick-walled component 3.
[0029] One side of the thick-walled component 3 is coated. The coating on one side of the thick-walled component 3 can directly provide physical protection to the surface of the thick-walled component 3, isolate it from external objects that may cause scratches, and effectively reduce the risk of scratches.
[0030] The surface of the thick-walled component 3 is provided with optical patterns. The optical patterns on the surface of the thick-walled component 3 can enhance its aesthetics, and the presence of the optical patterns can also disperse external forces to a certain extent, reducing scratches caused by excessive local stress.
[0031] The role and effect of the embodiments
[0032] The elastic plate 402 passes through the limiting groove 401. Since the elastic plate 402 has an L-shaped structure, its end abuts against the first extension plate 403. The upper decorative frame 1 and lower decorative frame 2 are connected together. Due to the presence of the first extension plate 403 and the second extension plate 404, a cavity exists between the upper decorative frame 1 and the lower decorative frame 2, and the thick-walled component 3 is located within this cavity. The gap between the thick-walled component 3 and the upper decorative frame 1 is 1mm, and the gap between the thick-walled component 3 and the lower decorative frame 2 is also 1mm, reducing the probability of scratching the thick-walled component 3. The inner part 5 of the frosting device abuts against the back of the thick-walled component 3, thus fixing the thick-walled component 3 between the upper decorative frame 1 and the lower decorative frame 2. By separating the upper decorative frame 1 and the lower decorative frame 2, the risk of the thick-walled component 3 being scratched by the decorative frames is reduced.
[0033] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
