Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a side taillight mounting structure, mounting method, automotive taillight, and automotive. Background Technology

[0002] With the rapid development of automobiles, the performance and quality of automotive taillights have been significantly improved. Novel and unique exterior designs will become a key focus for consumers. To make taillights look more technologically advanced and distinctive, maximizing the luminous area within a given size is an effective approach. Increasing the proportion of the luminous area while maintaining the same external shape results in a larger internal structure, requiring more internal structural space and a larger installation space. The taillight mounting plate, as a primary load-bearing component, provides positioning and mounting holes for the taillights. Its structure and precision are crucial for aesthetic matching and directly affect the fit between the taillights and surrounding components.

[0003] To maximize the luminous area of ​​the taillights, the non-luminous area needs to be minimized, and the luminous panel needs to be as close to the taillight boundary as possible. However, this increases the space required for the taillight housing. To provide sufficient installation space for the taillights, reducing the flange angle of the side panel is the only solution. However, reducing the flange angle of the side panel presents the following technical challenges:

[0004] 1) As the flange angle of the side panel decreases, the operating space of the welding gun also decreases, making it difficult to complete the welding between the side panel and the taillight mounting plate by spot welding.

[0005] 2) If advanced welding processes such as laser welding are used to replace spot welding, it requires high equipment investment and higher precision requirements for parts, and the production efficiency is low.

[0006] 3) The side panel outer edge angle is too small, which makes the taillight mounting plate have a negative angle in the stamping direction in the L1 area, making stamping difficult.

[0007] Therefore, there is a need to provide a taillight mounting structure that can accommodate taillights with high light emission ratios and is easy to form in order to solve the above-mentioned technical problems. Summary of the Invention

[0008] To address the aforementioned technical problems, this application provides a side taillight mounting structure. This solves the problem in the prior art where maximizing the taillight's luminous area results in a negative angle on the taillight mounting plate in the stamping direction, leading to difficulties in forming and a tendency to crack.

[0009] The technical effect of this application is achieved through the following:

[0010] A side panel taillight mounting structure includes a side panel outer plate and a taillight mounting plate assembly. The taillight mounting plate assembly includes a taillight mounting connecting plate, an upper taillight mounting plate, and a lower taillight mounting plate. The lower taillight mounting plate includes a first welding edge and a second welding edge, which are adjacent to each other. The taillight mounting connecting plate is welded to the first welding edge, and the upper taillight mounting plate is welded to the second welding edge. The taillight mounting connecting plate and the upper taillight mounting plate are respectively welded to the side panel outer plate. The taillight mounting plate assembly is formed by welding the taillight mounting connecting plate, the upper taillight mounting plate, and the lower taillight mounting plate together, which improves the precision of each part and solves the problem of negative angles in the stamping direction of the taillight mounting plate, which leads to difficult forming and easy cracking.

[0011] Furthermore, the outer side panel is provided with a flange, and the angle between the flange and the outer side panel is the flange angle. When the flange angle is less than or equal to a preset angle, the upper taillight mounting plate is welded to the outer side panel by cold arc welding; when the flange angle is greater than the preset angle, the upper taillight mounting plate is welded to the outer side panel by spot welding.

[0012] Furthermore, the upper taillight mounting plate is provided with a first overlapping edge, the first overlapping edge matches the taillight mounting connecting plate, and the taillight mounting connecting plate overlaps on the first overlapping edge.

[0013] Furthermore, the taillight mounting connecting plate and the first overlapping edge overlapping surface have a gap.

[0014] Furthermore, the lower taillight mounting plate is also provided with a second overlapping edge, which matches the taillight mounting connecting plate, and the taillight mounting connecting plate overlaps on the second overlapping edge.

[0015] Furthermore, a gap is provided between the taillight mounting connecting plate and the second overlapping edge. This gap between the taillight mounting connecting plate and the first and second overlapping edges allows for adjustment during the welding of the taillight mounting plate assembly, ensuring the accuracy of the mounting holes in the final welded assembly.

[0016] Furthermore, the outer side panel is provided with a welding surface, which is welded to the taillight mounting plate.

[0017] Furthermore, the welding surface is formed by folding the outer side panel. By using a folded edge structure on the outer side panel to create the welding surface for the taillight mounting connecting plate, it is beneficial to the forming of the outer side panel and avoids the problems of difficult forming of the outer side panel in this area, poor matching between the taillight and the vehicle body, and inconvenient installation.

[0018] Furthermore, it also includes a rear drainage channel, which is fixedly connected to the side panel.

[0019] Furthermore, the taillight mounting connecting plate is provided with a first taillight mounting hole, and the lower taillight mounting plate is also provided with a second taillight mounting hole and a third taillight mounting hole. These three taillight mounting holes are used to mount the vehicle taillights. The first taillight mounting hole serves as a positioning hole during welding of the taillight mounting connecting plate, and the second and third taillight mounting holes serve as positioning holes during welding of the lower taillight mounting plate. This ensures that the positioning holes for welding the taillight mounting plate assembly and the taillight mounting holes are consistent, maximizing the accuracy of the taillight mounting holes.

[0020] Furthermore, the lower taillight mounting plate also includes a first rear bumper mounting surface and a second rear bumper mounting surface, which are used to mount the vehicle's rear bumper.

[0021] Additionally, a method for installing side taillights is provided, the method being implemented based on the aforementioned installation structure, the method comprising:

[0022] The lower taillight mounting plate is welded to the upper taillight mounting plate through the second welding edge to form a complete taillight mounting plate.

[0023] Weld one end of the upper taillight mounting plate of the entire taillight mounting plate to the outer side panel.

[0024] Weld one end of the lower taillight mounting plate of the entire taillight mounting plate to the outer side panel.

[0025] The upper taillight mounting plate is provided with a first overlapping edge, the first overlapping edge matches the taillight mounting connecting plate, and the taillight mounting connecting plate overlaps on the first overlapping edge;

[0026] The lower taillight mounting plate is provided with a second overlapping edge, the second overlapping edge matches the taillight mounting connecting plate, and the taillight mounting connecting plate overlaps on the second overlapping edge;

[0027] Adjust the taillight mounting plate to overlap the first and second overlapping edges. Weld one end of the taillight mounting plate to the outer side panel and the other end to the first welding edge of the lower taillight mounting plate, thus completing the fixed connection between the taillight mounting plate assembly and the outer side panel.

[0028] In addition, a car taillight is also provided, including a taillight cover, a non-luminous area, a luminous panel, a taillight rear shell, and the aforementioned side taillight mounting structure. The taillight rear shell is mounted on the side taillight mounting structure, and the taillight cover is mounted on the taillight rear shell. The taillight cover has a non-luminous area and a luminous panel inside.

[0029] In addition, a car is provided, including the aforementioned taillights.

[0030] As described above, this application has the following beneficial effects:

[0031] 1) The taillight mounting plate assembly is welded together from three parts: the taillight mounting connecting plate, the upper taillight mounting plate, and the lower taillight mounting plate. This improves the precision of each part and solves the problem of the taillight mounting plate having a negative angle in the stamping direction, which leads to difficulties in forming and easy cracking.

[0032] 2) By using the taillight mounting connecting plate and the first and second overlapping edges in a non-fitted manner, the taillight mounting connecting plate can be adjusted during the welding of the taillight mounting plate assembly, thus ensuring the accuracy of the mounting holes in the final welded assembly.

[0033] 3) By adopting the side panel flange structure, the welding surface for welding the taillight mounting connection plate is realized, which is conducive to the forming of the side panel and avoids the problems of difficult forming of the side panel in this area, poor matching between the taillight and the body in this area, and inconvenient installation.

[0034] 4) In areas where spot welding is not feasible, cold arc welding was used to ensure a good match between the upper taillight mounting plate and the side panel.

[0035] 5) The first taillight mounting hole is used as the positioning hole for welding the taillight mounting plate, and the second and third taillight mounting holes are used as the positioning holes for welding the lower taillight mounting plate. This ensures that the positioning holes for welding the taillight mounting plate assembly are consistent with the taillight mounting holes, maximizing the accuracy of the taillight mounting holes.

Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0045] Example 1:

[0046] See Figure 1-4 This embodiment is a side panel taillight mounting structure, including a side panel outer plate 1 and a taillight mounting plate assembly 2. The side panel outer plate 1 and the taillight mounting plate assembly 2 are fixedly connected by welding. The taillight mounting plate assembly 2 includes a taillight mounting connecting plate 21, an upper taillight mounting plate 22, and a lower taillight mounting plate 23. The lower taillight mounting plate 23 includes a first welding edge 231 and a second welding edge 232, which are adjacent to each other. The taillight mounting connecting plate 21 is welded to the first welding edge 231, and the upper taillight mounting plate 22 is welded to the second welding edge 232. The taillight mounting connecting plate 21 and the upper taillight mounting plate 22 are respectively welded to the side panel outer plate 1. The taillight mounting plate assembly 2 is divided into three parts: the taillight mounting connecting plate 21, the upper taillight mounting plate 22, and the lower taillight mounting plate 23. This facilitates the forming of each part, improves the precision of each part, and solves the problem of the negative angle in the stamping direction of the taillight mounting plate, which leads to forming difficulties and easy cracking. The solution to the problem of cracked taillight mounting plate by splitting it into parts is not limited to the vertical splitting described in this application; other splitting methods, such as horizontal splitting, can also be used.

[0047] In this embodiment, the outer side panel 1 is further provided with a flange 12. The angle between the flange 12 and the outer side panel 1 is the flange angle, which is α. When the flange angle α is less than or equal to a preset angle, the upper taillight mounting plate 22 is welded to the outer side panel 1 by cold arc welding. When the flange angle α is greater than the preset angle, the upper taillight mounting plate 22 is welded to the outer side panel 1 by spot welding. The preset angle is 60-65 degrees. The flange angle α is 60≤α<90 degrees, preferably 60≤α<70 degrees, and more preferably 60 degrees. To provide the largest possible space for taillight installation, the flange angle α is reduced to its limit, approximately 60°. After reducing the flange angle α, the operating space of the welding gun cannot meet the requirements for welding gun operation. In this embodiment, cold arc welding is used instead of spot welding. The upper taillight mounting plate 22 is welded to the outer side panel 1 using cold arc welding. This solves the problem that ordinary spot welding cannot be implemented, avoids the high cost of equipment investment and low production efficiency associated with laser welding.

[0048] In this embodiment, the upper taillight mounting plate 22 has a first overlapping edge 221, which matches the taillight mounting connecting plate 21. The taillight mounting connecting plate 21 overlaps the first overlapping edge 221. The overlapping edges of the taillight mounting connecting plate 21 and the upper taillight mounting plate 22 match, and the corresponding two overlapping mating surfaces are not in a close-fitting state with a gap of approximately 1.5mm. The lower taillight mounting plate 23 also has a second overlapping edge 233, which matches the taillight mounting connecting plate 21. The taillight mounting connecting plate 21 overlaps the second overlapping edge 233. The overlapping edges of the taillight mounting connecting plate 21 and the lower taillight mounting plate 23 match, and the corresponding two overlapping mating surfaces are not in a close-fitting state with a gap of approximately 1.5mm. The purpose of the designed gap is to provide adjustment for the taillight mounting connecting plate 21 when welding the taillight mounting plate assembly 2, so as to ensure the accuracy of the mounting holes in the final welded assembly.

[0049] In this embodiment, the outer side panel 1 is provided with a welding surface 11, which is welded to the taillight mounting connecting plate 21. The welding surface 11 is formed by folding the outer side panel 1. In order to achieve... Figure 1The first weld point P1 is the weld point between the welding surface 11 and the taillight mounting connecting plate 21. In the prior art, the side panel outer plate is drawn into a pit-shaped structure to serve as the welding surface for welding with the taillight mounting connecting plate. However, the depth of the drawn side panel outer plate has certain requirements (usually greater than 8mm). Because the taillight's sharp corner has a shell structure, and this sharp corner is very unfavorable for formability, the forming accuracy of the side panel outer plate in this area is often poor, and the forming depth consistency is low, making it difficult to control the surface difference between the matching surfaces in this area when installing the taillight. This embodiment uses a flanged structure of the side panel outer plate to achieve the welding surface of the side panel outer plate in this area. This method is more advantageous for the forming of the side panel outer plate, solving the problem of difficult forming in this area, and the consistency of the side panel outer plate is higher, solving the problem of poor matching and poor installation consistency between the taillight and the vehicle body in this sharp corner area.

[0050] Furthermore, Figure 2 The sixth welding point P6 is the welding point between the upper taillight mounting plate 22 and the side outer panel 1. In order to ensure that the taillight mounting plate assembly 2 and the side outer panel 1 are well matched, the first welding point P1 and the sixth welding point P6 control the dimensional accuracy of the connection end between the taillight mounting plate assembly 2 and the side outer panel 1. At the same time, these two welding points should be as close as possible to the edge of the connection end of the side outer panel 1.

[0051] In this embodiment, a rear water channel 3 is also included, which is fixedly connected to the side outer panel 1. The taillight mounting connecting plate 21 is provided with a first taillight mounting hole 211, and the lower taillight mounting plate 23 is also provided with a second taillight mounting hole 234 and a third taillight mounting hole 235. The first taillight mounting hole 211, the second taillight mounting hole 234, and the third taillight mounting hole 235 are used to install the car taillights. The lower taillight mounting plate 23 also includes a first rear bumper mounting surface 236 and a second rear bumper mounting surface 237, which are used to install the car rear bumper. By using the first taillight mounting hole 211 as a positioning hole for welding the taillight mounting connecting plate 21, and by using the second taillight mounting hole 234 and the third taillight mounting hole 235 as positioning holes for welding the lower taillight mounting plate 23, the positioning holes for welding the taillight mounting plate assembly 2 and the taillight mounting holes are unified, ensuring the accuracy of the taillight mounting holes to the greatest extent.

[0052] Assembly process:

[0053] 1) The lower taillight mounting plate 23 is welded together with the upper taillight mounting plate 22 through the second welding edge 232 to form a complete taillight mounting plate. The second welding edge 232 and the upper taillight mounting plate 22 are spot welded together through the third welding point P3 to form a complete taillight mounting plate. There are two third welding points P3.

[0054] 2) The upper taillight mounting plate 22 of the entire taillight mounting plate is welded to the outer side panel 1 by cold arc welding at the seventh welding point P7 and spot welding at the sixth welding point P6. There are three seventh welding points P7 and two sixth welding points P6.

[0055] 3) One end of the lower taillight mounting plate 23 of the entire taillight mounting plate is spot welded to the outer side panel 1 through the fifth welding point P5. There are three fifth welding points P5.

[0056] 4) Adjust the taillight mounting connection plate 21 to overlap the first overlapping edge 221 and the second overlapping edge 233. Weld one end of the taillight mounting connection plate 21 to the outer side panel 1 through the first welding point P1 and the fourth welding point P4. Weld the other end of the taillight mounting connection plate 21 to the first welding edge 231 of the lower taillight mounting plate 23 through the second welding point P2. There is one first welding point P1, three fourth welding points P4, and two second welding points P2.

[0057] 5) To ensure the accuracy and consistency of the welding between the taillight mounting plate assembly 2 and the side panel 1, spot welding should be used for all welding points except for the seventh welding point P7. In areas where spot welding is not feasible, cold arc welding should be used to complete the fixed connection between the taillight mounting plate assembly 2 and the side panel 1.

[0058] Example 2:

[0059] See Figure 1-5This embodiment is a car taillight, including a taillight cover 4, a non-light-emitting area 5, a light-emitting plate 6, a taillight rear shell 7, and the side taillight mounting structure of Embodiment 1. The taillight rear shell 7 is mounted on the side taillight mounting structure, and the taillight cover 4 is mounted on the taillight rear shell 7. The taillight cover 4 has a non-light-emitting area 5 and a light-emitting plate 6 inside. To maximize the light-emitting area of ​​the taillight, the distance of the non-light-emitting area 5 is shortened, so that the light-emitting plate 6 is closer to the taillight boundary, increasing the space of the taillight rear shell 7. To provide a sufficiently large mounting space for the taillight, reducing the flange angle α of the side outer panel 1 is the only solution. However, as the flange angle α decreases, the welding gun operating space S1 using spot welding also decreases, making it difficult to achieve the seventh welding point P7. The welding gun operating space S1 is the distance from the seventh welding point P7 in the vertical direction to the flange 12 of the side outer panel 1. Typically, the minimum value of the welding gun operating space S1 is about 52mm. Reducing the flange angle α makes the value of the welding gun operating space S1 much smaller than 52mm, making ordinary spot welding impossible. Furthermore, the traditional taillight mounting plate has a negative angle in the stamping direction in the first area L1, making stamping difficult. This application reduces the flange angle α of the side outer panel 1 to its limit, about 60°, and uses cold arc welding to replace spot welding, solving the problem that ordinary spot welding cannot be implemented. The traditional taillight mounting plate is disassembled into multiple smaller parts, and then connected by spot welding to form the taillight mounting plate assembly, solving the problems of difficult negative angle forming and easy cracking of the traditional taillight mounting plate.

[0060] As described above, this application has the following beneficial effects:

[0061] 1) The taillight mounting plate assembly 2 is welded together from three parts: taillight mounting connecting plate 21, upper taillight mounting plate 22 and lower taillight mounting plate 23. This improves the precision of each part and solves the problem that the taillight mounting plate has a negative angle in the stamping direction, which makes it difficult to form and easy to crack.

[0062] 2) By non-fitting the taillight mounting connecting plate 21 with the first overlapping edge 221 and the second overlapping edge 233, the taillight mounting connecting plate 21 can be adjusted during the welding of the taillight mounting plate assembly 2, thus ensuring the accuracy of the mounting holes in the final welded assembly.

[0063] 3) By adopting the side panel flange structure, the welding surface for welding the taillight mounting connecting plate 21 is realized, which is conducive to the forming of the side panel 1 and avoids the problems of difficult forming of the side panel 1 in this area, poor matching between the taillight and the body in this area, and inconvenient installation.

[0064] 4) In areas where spot welding is not feasible, cold arc welding is used to ensure a good match between the upper taillight mounting plate 22 and the side panel 1.

[0065] 5) The first taillight mounting hole 211 is used as the positioning hole for welding the taillight mounting connecting plate 21, and the second taillight mounting hole 234 and the third taillight mounting hole 235 are used as the positioning holes for welding the lower taillight mounting plate 23. This makes the positioning holes for welding the taillight mounting plate assembly 2 and the taillight mounting holes consistent, thus maximizing the accuracy of the taillight mounting holes.
