Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a taillight structure and a vehicle. Background Technology

[0002] With the development of the automotive industry, continuous taillights not only increase the overall vehicle's recognizability but also enhance its design aesthetics. As technology advances, the single-position light function of rear continuous taillights can no longer satisfy people's pursuit of technological beauty. Rear continuous taillights with light curtains can enhance warning signals in foggy, snowy, or rainy weather, making it easier for following vehicles to see the distance, increasing driving safety, improving the vehicle's intelligence, and enhancing its overall aesthetics.

[0003] Currently, the light curtain solutions used for vehicle rear through lights are mostly a combination of flexible and rigid boards. The rigid LED driver board is more often used in relatively flat areas, making it difficult to apply to through lights with greater curvature, resulting in larger gaps between adjacent LED mounting boards. Utility Model Content

[0004] This application provides a taillight structure and vehicle, which solves the technical problem of large gaps in the taillight structure and achieves the technical effect of reducing the large gaps in the taillight structure.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a taillight structure, including a first bracket, an LED chip plate, and a drive plate. The first bracket includes a first main positioning post and a second main positioning post, which are spaced apart along the left-right direction. The LED chip plate and the drive plate are arranged sequentially along the left-right direction, and the LED chip plate and the drive plate respectively have a first end and a second end close to each other. The first end is provided with a first main hole, and the second end is provided with a second main hole. The first main hole cooperates with the first main positioning post, and the second main hole cooperates with the second main positioning post.

[0007] This application proposes a taillight structure in which the LED chip plate and the driver plate are positioned on the side close to each other. The LED chip plate and the driver plate are positioned by the first main positioning post and the second main positioning post, respectively, which reduces the tilting or movement of the LED chip plate and the driver plate on the side close to each other, thereby improving the positioning accuracy of the LED chip plate and the driver plate, reducing the gap between the LED chip plate and the driver plate, and thus improving the aesthetics of the taillight. In addition, this structure is simple to set up, easy to install, and low in cost.

[0008] Optionally, the first bracket further includes a first auxiliary positioning post and a second auxiliary positioning post. The first auxiliary positioning post is located on the side of the first main positioning post away from the second main positioning post, and the second auxiliary positioning post is located on the side of the second main positioning post away from the first main positioning post. The lamp bead board has a first auxiliary hole, and the drive board has a second auxiliary hole. The first auxiliary hole cooperates with the first auxiliary positioning post, and the second auxiliary hole cooperates with the second auxiliary positioning post.

[0009] In the above embodiments, the first auxiliary positioning post is used in conjunction with the first main positioning post to position the LED bead board, which can further reduce the skewness or displacement of the LED bead board; the second auxiliary positioning post is used in conjunction with the second main positioning post to position the drive board, which can further reduce the skewness or displacement of the drive board, thereby reducing the joint gap between the LED bead board and the drive board.

[0010] Optionally, there are multiple first auxiliary positioning posts, which are spaced apart along the left-right direction; there are multiple second auxiliary positioning posts, which are spaced apart along the left-right direction; there are multiple first auxiliary holes, which are spaced apart along the left-right direction, and each of the multiple first auxiliary holes corresponds to one of the multiple first auxiliary positioning posts; there are multiple second auxiliary holes, which are spaced apart along the left-right direction, and each of the multiple second auxiliary holes corresponds to one of the multiple second auxiliary positioning posts.

[0011] In the above embodiments, multiple first auxiliary positioning posts and first main positioning posts are used together to position the LED bead board in the left and right directions, and multiple second auxiliary positioning posts and second main positioning posts are used together to position the drive board in the left and right directions, thereby reducing the splicing gap between the LED bead board and the drive board.

[0012] Optionally, both the first main hole and the second main hole are constructed as circular holes, and both the first auxiliary hole and the second auxiliary hole are constructed as oblong holes, wherein the length direction of the oblong hole is parallel to the left-right direction.

[0013] In the above embodiments, the first main hole is a circular hole, which can reduce the rotation or offset of the LED board near the driver board. The first auxiliary hole is an oblong hole, which facilitates the installation of the LED board and can compensate for the deformation of the LED board, thereby positioning the LED board. The second main hole is a circular hole, which can reduce the rotation or offset of the driver board near the LED board. The second auxiliary hole is an oblong hole, which facilitates the installation of the driver board and can compensate for the deformation of the driver board, thereby positioning the driver board.

[0014] Optionally, the taillight structure also includes a decorative ring connected to the first bracket. The decorative ring has a first protrusion on the side facing the first bracket, and a portion of the first protrusion abuts against the lamp bead plate and the drive plate.

[0015] In the above embodiment, the decorative ring is provided on the first bracket, and the first protrusion on the decorative ring abuts against the lamp bead plate and the driver plate, which can tightly attach the lamp bead plate and the driver plate to the first bracket, thereby reducing the light leakage and light scattering of the taillight.

[0016] Optionally, along the vertical direction, the first bracket has a third end and a fourth end disposed opposite to each other, the third end being closer to the first main positioning post and the second main positioning post than the fourth end, and the third end having a second protrusion extending toward the decorative ring; the first protrusion includes a first sub-protrusion, the first sub-protrusion being disposed on the side of the decorative ring near the first end, and along the vertical direction, the projection of the second protrusion at least partially overlaps with the projection of the first sub-protrusion.

[0017] In the above embodiment, the first sub-protrusion extends toward the first bracket, and the second protrusion extends toward the trim ring. The first sub-protrusion and the second protrusion are misaligned, thereby reducing the taillight's light leakage.

[0018] Optionally, the first protrusion includes two second sub-protrusions, which are disposed on both sides of the decorative ring in the left-right direction. The first bracket is provided with a third protrusion on both sides in the left-right direction. In the left-right direction, the projection of the second sub-protrusion at least partially overlaps with the projection of the corresponding third protrusion.

[0019] In the above embodiment, along the left-right direction, the projection of the second sub-protrusion on the left side at least partially overlaps with the projection of the third protrusion on the left side, which can reduce light leakage and light crosstalk on the left side of the taillight; the projection of the second sub-protrusion on the right side at least partially overlaps with the projection of the third protrusion on the right side, which can reduce light leakage and light crosstalk on the right side of the taillight.

[0020] Optionally, along the vertical direction, the first bracket has a third end and a fourth end that are disposed opposite to each other, the third end being closer to the first main positioning post and the second main positioning post than the fourth end; the taillight structure further includes a second bracket, the second bracket being disposed at the fourth end, and the second bracket and the first bracket clamping the lamp bead plate and the drive plate.

[0021] In the above embodiment, the second bracket is disposed at the fourth end of the first bracket to sandwich the lamp bead board and the driver board between the first bracket and the second bracket, thereby strengthening the fixation of the lamp bead board and the driver board while reducing light crosstalk and light leakage.

[0022] Optionally, the second bracket has a pin hole and a rib. Along the front-rear direction, the pin hole passes through the second bracket, and the rib is located on the side of the second bracket away from the lamp bead board and the drive board. The first bracket is provided with a pin, which includes a connecting part and an abutting part connected at an angle. The connecting part is connected to the first bracket, the connecting part passes through the pin hole, and the abutting part abuts against the rib.

[0023] In the above embodiment, after the pin passes through the pin hole, the abutment part presses against the protruding rib to press the second bracket toward the first bracket, and the second bracket presses the lamp bead board and the driver board onto the first bracket.

[0024] Secondly, this application also provides a vehicle including the taillight structure described in any of the above embodiments. The vehicle includes the taillight structure described in any of the above embodiments, where the LED chip plate and the drive plate are positioned on the side closest to each other by a first main positioning post and a second main positioning post, respectively. This reduces the likelihood of the LED chip plate and the drive plate tilting or moving on the side closest to each other, reduces the gap between the LED chip plate and the drive plate, thereby improving the aesthetics of the taillight. Furthermore, this structure is simple to set and has low cost. Attached Figure Description

[0046] Currently, the light curtain solutions used for vehicle rear through lights are mostly a combination of flexible and rigid boards, with low pixel counts and usually large gaps between LEDs. Compared to existing light curtains, an additional LED driver rigid board is added. However, LED driver rigid boards are more commonly used in relatively flat areas, making them difficult to apply to through lights with large curvatures, especially rigid board light curtains with large curvature and high pixel counts. The gaps between adjacent LED mounting plates are large, resulting in low assembly reliability, high production costs, and low assembly efficiency.

[0047] In view of this, this application provides a taillight structure that has precise positioning, simple assembly process, and can improve the assembly efficiency of the production line, meet the styling requirements, and reduce manufacturing costs.

[0048] In this application, the left-right direction X is the direction of action of the vehicle, the up-down direction Y is the up-down direction of the vehicle, and the front-back direction Z is the front-back direction of the vehicle. The front-back direction Z of the vehicle is parallel to the thickness direction of the first bracket 1, the left-right direction X of the vehicle is parallel to the length direction of the first bracket 1, and the up-down direction Y of the vehicle is parallel to the width direction of the first bracket 1.

[0049] Firstly, reference Figure 1 and Figure 2 This application provides a taillight structure, which includes a first bracket 1, an LED bead plate 2, and a drive plate 3. The first bracket 1 includes a first main positioning post 11 and a second main positioning post 12, which are spaced apart along the left-right direction X. The LED bead plate 2 and the drive plate 3 are arranged sequentially along the left-right direction X, and the LED bead plate 2 and the drive plate 3 respectively have a first end 21 and a second end 31 close to each other. The first end 21 is provided with a first main hole 22, and the second end 31 is provided with a second main hole 32. The first main hole 22 cooperates with the first main positioning post 11, and the second main hole 32 cooperates with the second main positioning post 12.

[0050] The first main hole 22 is located at the first end 21 and near the edge where the LED bead plate 2 and the drive plate 3 abut. The second main hole 32 is located at the second end 31 and near the edge where the drive plate 3 and the LED bead plate 2 abut. The first main hole 22 and the second main hole 32 are close to each other. When the drive plate 3 and the LED bead plate 2 are installed on the first bracket 1, the first main hole 22 is engaged with the first main positioning post 11, and the second main hole 32 is engaged with the second main positioning post 12. The first main positioning post 11 is located at the first end 21 of the LED bead plate 2, and the second main positioning post 12 is located at the second end 31 of the drive plate 3. The first main positioning post 11 and the second main positioning post 12 position the LED bead plate 2 and the drive plate 3 respectively on the side where the LED bead plate 2 and the drive plate 3 are close to each other, thereby reducing the tilting or movement of the LED bead plate 2 and the drive plate 3 on the side where they are close to each other, thereby reducing the increase in gap between the LED bead plate 2 and the drive plate 3 caused by the positional offset between the LED bead plate 2 and the drive plate 3.

[0051] In other words, the LED chip board 2 and the drive board 3 are positioned on the side close to each other by the first main positioning post 11 and the second main positioning post 12 respectively. This can improve the positioning accuracy of the LED chip board 2 and the drive board 3, reduce the gap between the LED chip board 2 and the drive board 3, thereby improving the aesthetics of the taillight. Moreover, this structure is simple to set up and has low cost.

[0052] It should be noted that in this application, the LED board 2 is a mounting board on which LEDs are installed, and the driver board 3 is a mounting board on which both LEDs and the driver are installed. In other words, by mounting the driver on the mounting board with LEDs, the additional mounting board used for mounting the driver can be reduced, thereby saving costs.

[0053] Optionally, refer to Figure 1 and Figure 2The first bracket 1 also includes a first auxiliary positioning post 13 and a second auxiliary positioning post 14. The first auxiliary positioning post 13 is located on the side of the first main positioning post 11 away from the second main positioning post 12, and the second auxiliary positioning post 14 is located on the side of the second main positioning post 12 away from the first main positioning post 11. The lamp bead plate 2 has a first auxiliary hole 23, and the drive plate 3 has a second auxiliary hole 33. The first auxiliary hole 23 cooperates with the first auxiliary positioning post 13, and the second auxiliary hole 33 cooperates with the second auxiliary positioning post 14.

[0054] Along the left-right direction X, the first auxiliary positioning post 13 and the first main positioning post 11 are used to cooperate with the first auxiliary hole 23 and the first main hole 22 of the lamp bead plate 2 respectively to position the lamp bead plate 2. The first auxiliary positioning post 13 and the first main positioning post 11 cooperate to position the lamp bead plate 2, which can further reduce the skewness or displacement of the lamp bead plate 2. Along the left-right direction X, the second auxiliary positioning post 14 and the second main positioning post 12 are used to cooperate with the second auxiliary hole 33 and the second main hole 32 of the drive plate 3 respectively to position the drive plate 3. The second auxiliary positioning post 14 and the second main positioning post 12 cooperate to position the drive plate 3, which can further reduce the skewness or displacement of the drive plate 3, thereby reducing the joint gap between the lamp bead plate 2 and the drive plate 3.

[0055] Optionally, refer to Figure 1 and Figure 2 There are multiple first auxiliary positioning posts 13, which are spaced apart along the left-right direction X; there are multiple second auxiliary positioning posts 14, which are spaced apart along the left-right direction X; there are multiple first auxiliary holes 23, which are spaced apart along the left-right direction X, and each first auxiliary hole 23 corresponds to one of the multiple first auxiliary positioning posts 13; there are multiple second auxiliary holes 33, which are spaced apart along the left-right direction X, and each second auxiliary hole 33 corresponds to one of the multiple second auxiliary positioning posts 14.

[0056] Multiple first auxiliary positioning posts 13 and first main positioning posts 11 work together to position the LED bead board 2 in the left-right direction X, thereby improving the positioning accuracy of the LED bead board 2; multiple second auxiliary positioning posts 14 and second main positioning posts 12 work together to position the drive board 3 in the left-right direction X, thereby improving the positioning accuracy of the drive board 3 and reducing the gap between the LED bead board 2 and the drive board 3.

[0057] Optionally, refer to Figure 1 and Figure 2 The first main hole 22 and the second main hole 32 are both constructed as circular holes, and the first auxiliary hole 23 and the second auxiliary hole 33 are both constructed as oblong holes, with the length direction of the oblong holes being parallel to the left-right direction X.

[0058] The first main hole 22 is a circular hole, which can reduce the rotation or offset of the LED chip board 2 near the drive board 3. The first auxiliary hole 23 is an oblong hole, which facilitates the installation of the LED chip board 2. Even if the LED chip board 2 is deformed, the larger size of the first auxiliary hole 23 can compensate for the deformation of the LED chip board 2, thereby positioning the LED chip board 2 and improving the positioning accuracy of the LED chip board 2. The second main hole 32 is a circular hole, which can reduce the rotation or offset of the drive board 3 near the LED chip board 2. The second auxiliary hole 33 is an oblong hole, which facilitates the installation of the drive board 3. Even if the drive board 3 is deformed, the larger size of the second auxiliary hole 33 can compensate for the deformation of the drive board 3, thereby positioning the drive board 3 and improving the positioning accuracy of the drive board 3.

[0059] In addition, the first main hole 22 and the second main hole 32 respectively provided on the side of the lamp bead board 2 and the driver board 3 that are close to each other are circular holes, and the first auxiliary hole 23 and the second auxiliary hole 33 respectively provided on the side of the lamp bead board 2 and the driver board 3 that are far from each other are elongated holes. This can compensate for the deformation of the lamp bead board 2 and the driver board 3 and facilitate installation. At the same time, it can also reduce the interference between the side of the lamp bead board 2 that is far from the driver board 3 and the first bracket 1, and reduce the interference between the side of the driver board 3 that is far from the lamp bead board 2 and the first bracket 1.

[0060] Optionally, refer to Figure 1 and Figure 3 The taillight structure also includes a decorative ring 4, which is connected to the first bracket 1. The decorative ring 4 has a first protrusion 41 on the side facing the first bracket 1, and part of the first protrusion 41 abuts against the lamp bead plate 2 and the drive plate 3.

[0061] The decorative ring 4 is located on the first bracket 1. Part of the first protrusion 41 on the decorative ring 4 abuts against the lamp bead plate 2 and the drive plate 3, which can tightly attach the lamp bead plate 2 and the drive plate 3 to the first bracket 1, thereby reducing the taillight's light leakage.

[0062] Optionally, refer to Figure 1 and Figure 3 Along the vertical direction Y, the first bracket 1 has a third end 15 and a fourth end 16 disposed opposite to each other. The third end 15 is closer to the first main positioning post 11 and the second main positioning post 12 than the fourth end 16. The third end 15 has a second protrusion 17 extending toward the decorative ring 4. The first protrusion 41 includes a first sub-protrusion 411, which is disposed on the side of the decorative ring 4 near the first end 21. Along the vertical direction Y, the projection of the second protrusion 17 at least partially overlaps with the projection of the first sub-protrusion 411.

[0063] The first sub-protrusion 411 extends toward the first bracket 1, and the second protrusion 17 extends toward the decorative ring 4. The first sub-protrusion 411 and the second protrusion 17 are misaligned, thereby reducing the taillight's light leakage.

[0064] Optionally, refer to Figure 4 The first protrusion 41 includes two second sub-protrusions 412, which are located on both sides of the decorative ring 4 along the left-right direction X. The first bracket 1 has a third protrusion 18 on both sides along the left-right direction X. Along the left-right direction X, the projection of the second sub-protrusion 412 and the projection of the corresponding third protrusion 18 at least partially overlap.

[0065] The decorative ring 4 has a second sub-protrusion 412 on both sides along the left-right direction X, and the first bracket 1 has a third protrusion 18 on both sides along the left-right direction X. Along the left-right direction X, the projection of the second sub-protrusion 412 on the left side and the projection of the third protrusion 18 on the left side at least partially overlap, so that the second sub-protrusion 412 on the left side and the third protrusion 18 on the left side are misaligned, which can reduce light leakage and light scattering on the left side of the taillight; along the left-right direction X, the projection of the second sub-protrusion 412 on the right side and the projection of the third protrusion 18 on the right side at least partially overlap, so that the second sub-protrusion 412 on the right side and the third protrusion 18 on the right side are misaligned, which can reduce light leakage and light scattering on the right side of the taillight.

[0066] Optionally, refer to Figure 1 and Figure 5 Along the vertical direction Y, the first bracket 1 has a third end 15 and a fourth end 16 that are arranged opposite to each other. The third end 15 is closer to the first main positioning post 11 and the second main positioning post 12 than the fourth end 16. The taillight structure also includes a second bracket 5, which is located at the fourth end 16. The second bracket 5 and the first bracket 1 sandwich the lamp bead plate 2 and the drive plate 3.

[0067] The second bracket 5 is located at the fourth end 16 of the first bracket 1 to clamp the lamp bead board 2 and the driver board 3 between the first bracket 1 and the second bracket 5, thereby strengthening the fixation of the lamp bead board 2 and the driver board 3 while reducing light leakage and cross-contamination.

[0068] Optionally, refer to Figure 3 The second bracket 5 has a fourth protrusion 51 extending toward the first bracket 1. The first protrusion 41 includes a third sub-protrusion 413 located below the trim ring 4. Along the vertical direction Y, the projection of the third sub-protrusion 413 at least partially overlaps with the projection of the fourth protrusion 51. The third sub-protrusion 413 and the fourth protrusion 51 are misaligned, which can reduce the light leakage and light scattering of the taillight.

[0069] The first protrusion 41 of the decorative ring 4 presses against the upper part of the LED bead plate 2 and the drive plate 3, while the second bracket 5 presses against the lower part of the LED bead plate 2 and the drive plate 3, thereby pressing the LED bead plate 2 and the drive plate 3 firmly onto the first bracket 1. Furthermore, the first sub-protrusion 411 and the second protrusion 17 are misaligned on the upper side of the taillight, the second sub-protrusion 412 and the third protrusion 18 are misaligned on the left and right sides of the taillight, and the fourth protrusion 51 and the fifth protrusion are misaligned on the lower side of the taillight, thereby reducing light leakage and cross-beaming of the taillight. The first sub-protrusion 411 and the second bracket 5 press against the upper and lower sides of the LED bead plate 2 and the drive plate 3 respectively, thereby firmly pressing the LED bead plate 2 and the drive plate 3 onto the first bracket 1.

[0070] Optionally, refer to Figure 6 The second bracket 5 has a pin hole 52 and a rib 53. Along the front-rear direction Z, the pin hole 52 passes through the second bracket 5, and the rib 53 is located on the side of the second bracket 5 away from the LED bead board 2 and the driver board 3. The first bracket 1 has a pin 19, which includes a connecting part 191 and an abutting part 192 connected at an angle. The connecting part 191 connects to the first bracket 1 and passes through the pin hole 52. The abutting part 192 abuts against the rib 53. After the pin 19 passes through the pin hole 52, the abutting part 192 presses against the rib 53 to press the second bracket 5 towards the first bracket 1. The second bracket 5 presses the LED bead board 2 and the driver board 3 against the first bracket 1. The rib 53 is located on the side of the second bracket 5 away from the first bracket 1. The position of the rib 53 can be determined according to specific circumstances, as long as the abutting part 192 presses against the rib 53, thereby pressing the second bracket 5 towards the first bracket 1.

[0071] Secondly, embodiments of this application also provide a vehicle including the taillight structure described in any of the above embodiments. This vehicle possesses the beneficial effects of the taillight structure described in any of the above embodiments.

[0072] In this application, the third end 15 and the fourth end 16 of the first bracket 1 are each provided with multiple positioning holes. The positioning holes of the third end 15 and the fourth end 16 may include a circular main positioning hole and multiple oblong auxiliary positioning holes. The fourth end 16 of the first bracket 1 is also provided with a snap-fit ​​interface for connecting with the snap-fit ​​member on the decorative ring 4. The decorative ring 4 is connected to the third end 15 of the first bracket 1 through a positioning post and a positioning hole, and the decorative ring 4 is connected to the fourth end 16 of the first bracket 1 through a snap-fit ​​connection.

[0073] The specific installation method of the taillight structure in this application is as follows: First, place the first bracket 1 on the fixture, attach the double-sided adhesive 6 to the corresponding position of the first bracket 1, then position the first end 21 of the LED bead board 2 through the first main positioning post 11 and the first auxiliary positioning post 13 on the third end 15 of the first bracket 1, and position the second end 31 of the driver board 3 through the second main positioning post 12 and the second auxiliary positioning post 14 on the third end 15. Then, place the LED bead board 2 and the driver board 3 with the LED side facing up on the first bracket 1 and install them into the first bracket 1. The LED side of the LED bead board 2 and the driver board 3 is supported by the fixture's sponge soft surface to ensure that the light curtain rigid plate is firmly adhered to the double-sided adhesive 6 and that the LED beads are not damaged. After the drive board 3 is installed on the first bracket 1, the tooling sponge is removed. Then, the second bracket 5 is positioned through the main positioning hole and auxiliary positioning hole on the fourth end 16 of the first bracket 1, and then tightened with 6 screws. The pin 19 fixes the second bracket 5 to the first bracket 1. Finally, the decorative ring 4 is positioned through the main positioning hole and auxiliary positioning hole on the third end 15 of the first bracket 1, and then the upper end of the decorative ring 4 is tightened to the first bracket 1 with 7 screws. The lower end of the decorative ring 4 is inserted into the first bracket 1 through 6 clips. Finally, the taillight light curtain sub-assembly is completed. After the lamp bead board 2 and the drive board 3 are fixed with double-sided tape, the lamp bead board 2 and the drive board 3 are clamped to the first bracket 1 by the second bracket 5 and the decorative ring 4 respectively.

[0074] The LED chip board 2 and driver board 3 are PCB boards. Due to tolerances in the PCB board manufacturing process and the relatively long length of the LED chip board 2 and driver board 3, each board requires one main positioning and two auxiliary positioning. To minimize the gap between the LED chip board 2 and the driver board 3, the main positioning is placed at the seam between them, and the auxiliary positioning is arranged at intervals in the left-right (X) direction. The tolerance for the main positioning is ±0.1mm, and the tolerance for the auxiliary positioning is ±0.1mm in the up-down (Y) direction. Additional allowance can be added in the left-right (X) direction to minimize the gap between the LED chip board 2 and driver board 3 and save assembly time. To ensure that the LED chip board 2 and driver board 3 can be bent according to the curvature of the shape, the board thickness can be 0.8mm. The taillight LEDs can be LEDs, with a size of 2×1.6mm and a gap of 0.9mm between them.

[0075] The first sub-protrusion 411 on the upper side of the decorative ring 4 is close to the LED bead plate 2 and the driver plate 3, which can not only clamp the LED bead plate 2 and the driver plate 3, but also effectively prevent light leakage and light spurs from the light curtain. The double-sided adhesive between the LED bead plate 2 and the driver plate 3 and the first bracket 1 interferes with the LED bead plate 2 and the driver plate 3 by 0.1mm. Since the double-sided adhesive has a compression amount, the interference of 0.1mm can absorb the assembly problems caused by the thickness tolerance of the LED bead plate 2 and the driver plate 3. On the lower side of the taillight, the fourth protrusion 51 on the second bracket 5 intersects with the third sub-protrusion 413 of the decorative ring 4. On the upper side of the taillight, the second protrusion 17 on the first bracket 1 intersects with the first sub-protrusion 411 of the decorative ring 4. On the left and right sides of the taillight, the third protrusion 18 on the first bracket 1 intersects with the second sub-protrusion 412 of the decorative ring 4, which plays a role in preventing light leakage and light spurs from the light curtain.
