Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to an A-light assembly structure, a rear body structure, and a vehicle. Background Technology

[0002] In related technologies, as basic automotive functions are met, consumers are increasingly demanding more refined car exteriors, especially the rear area, which directly impacts customer perception of the vehicle. The A-light, as a finishing touch to the rear design, is particularly sensitive to gaps, surface differences, and alignment in the exterior design. The A-light area involves complex component matching and numerous dimensional links, leading to accumulated tolerances. This has made the DTS (gap, surface difference, alignment) issues between the A-light and the side panels and B-light a persistent pain point for various car models. Utility Model Content

[0003] In view of this, the present invention provides an A-lamp assembly structure, which reduces the final installation position deviation of the A-lamp caused by the accumulated tolerance of intermediate parts, improves assembly consistency, and enhances the matching accuracy of DTS (gap, surface difference, alignment).

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] In a first aspect, this utility model provides an A-lamp assembly structure, comprising: an A-lamp having a first positioning part and a second positioning part; a mounting plate having a first mating positioning part formed thereon, the first positioning part cooperating with the first mating positioning part to limit the relative position of the A-lamp and the mounting plate in the X and Z directions; and a mounting supplement plate connected to the mounting plate, the mounting supplement plate having a second mating positioning part formed thereon, the second positioning part cooperating with the second mating positioning part to limit the relative position of the A-lamp and the mounting supplement plate in the Y and Z directions.

[0006] According to the A-lamp assembly structure of this utility model, by forming a second mating positioning part on the mounting plate that cooperates with the second positioning part, the final installation position deviation of the A-lamp caused by the cumulative tolerance of intermediate parts is reduced, the assembly consistency is improved, and the X, Y, and Z dimensional links of the A-lamp mounting point are shortened, that is, the influence of the dimensional tolerance of the mounting plate on the assembly of A-lamp is reduced. By setting two positioning points, the matching accuracy of DTS (gap, surface difference, alignment) is improved, thereby improving product quality.

[0007] In one possible implementation of this utility model, one of the first mating positioning part and the first positioning part is formed as a positioning hole, and the other of the first mating positioning part and the first positioning part is formed as a positioning pin. The positioning pin extends into the positioning hole to position the A lamp in the X and Z directions.

[0008] Thus, by setting the first mating positioning part and the first positioning part to cooperate, the positional restriction between the A lamp and the mounting plate is realized, the matching accuracy of DTS (gap, surface difference, alignment) is improved, the dimensional chain of the A lamp mounting point in the X and Z directions is shortened, and the cooperation between the positioning pin and the positioning hole can improve the assembly stress and improve the stability of the connection structure between the A lamp and the mounting plate.

[0009] In one possible implementation of this utility model, one of the second mating positioning part and the second positioning part is formed as a positioning hole, and the other of the second mating positioning part and the second positioning part is formed as a positioning pin. The positioning pin extends into the positioning hole to position the A lamp in the Y direction and the Z direction.

[0010] Thus, by setting up a second mating positioning part and cooperating with the second positioning part, the positional constraint between lamp A and the mounting plate is realized, the matching accuracy of DTS (gap, surface difference, alignment) is improved, the dimensional chain in the Y and Z directions of lamp A mounting point is shortened, and the cooperation between the positioning pin and the positioning hole can improve the assembly stress and improve the stability of the connection structure between lamp A and the mounting plate.

[0011] In one possible implementation of this utility model, the A-lamp assembly structure further includes: a side outer panel, on which a third mating positioning part is formed, the A-lamp having a third positioning part, the third positioning part cooperating with the third mating positioning part to limit the relative position of the A-lamp and the side outer panel in the X and Y directions.

[0012] Thus, by forming a third mating positioning part on the outer side panel that cooperates with the third positioning part, the final installation position deviation of the A lamp caused by the cumulative tolerance of intermediate parts is reduced, the assembly consistency is improved, the Y-axis and X-axis dimensional links of the A lamp installation point are shortened, that is, the dimensional tolerance of the mounting plate is reduced on the assembly of A lamps, and the matching accuracy of DTS (gap, surface difference, alignment) is improved by setting three positioning points, thereby further improving product quality.

[0013] In one possible implementation of this utility model, one of the third mating positioning part and the third positioning part is formed as a positioning hole, and the other of the third mating positioning part and the third positioning part is formed as a positioning pin. The positioning pin extends into the positioning hole to position the A lamp in the X and Y directions.

[0014] Thus, by setting up a third mating positioning part and a third positioning part to cooperate, the positional restriction between the A-lamp and the side panel is realized, the matching accuracy of DTS (gap, surface difference, alignment) is improved, the dimensional chain in the Y and X directions of the A-lamp mounting point is shortened, and the cooperation between the positioning pin and the positioning hole can improve the assembly stress and improve the structural stability of the connection between the A-lamp and the side panel.

[0015] In one possible implementation of this utility model, the side panel has a first mating surface, the A-lamp has a second mating surface, and the first mating surface is in contact with the second mating surface.

[0016] In this way, by setting the first mating surface and the second mating surface, gaps between the A-lamp and the outer side panel are avoided, tolerance compensation improves assembly tolerance, sealing performance and protection performance, and improves the appearance quality of the vehicle.

[0017] In one possible implementation of this utility model, a first mounting portion is formed on the mounting plate, and a second mounting portion is formed on the A-lamp. The mounting plate and the A-lamp are mounted together through the first mounting portion and the second mounting portion.

[0018] In this way, by setting up the first mounting part and the second mounting part to cooperate, the functions of positioning and connection are decoupled, the connection stability between the A-lamp and the mounting plate is improved, thereby ensuring the long-term stability of the appearance matching.

[0019] In one possible implementation of this utility model, a fourth mating positioning part is formed on the mounting plate, and a fourth positioning part is formed on the A lamp. The fourth positioning part and the fourth mating positioning part cooperate to limit the relative position of the A lamp and the mounting plate in the Y direction.

[0020] Thus, by setting up a fourth mating positioning part and a fourth positioning part to cooperate, the positional constraint between lamp A and the mounting plate is realized, the matching accuracy of DTS (gap, surface difference, alignment) is improved, the dimensional chain in the Y direction of lamp A mounting point is shortened, and the cooperation between the positioning pin and the positioning hole can improve the assembly stress and improve the stability of the connection structure between lamp A and the mounting plate.

[0021] Secondly, this utility model embodiment provides a rear vehicle structure, including the A-lamp assembly structure provided in any of the embodiments of the first aspect above.

[0022] The rear structure of the vehicle body provided in this embodiment of the utility model has the same technical effect as the A-light assembly structure provided in any of the embodiments of the first aspect. That is, by forming a second mating positioning part that cooperates with the second positioning part on the mounting plate, the deviation of the final installation position of the A-light caused by the accumulated tolerance of intermediate parts is reduced, the assembly consistency is improved, the Y-axis and Z-axis dimensional links of the A-light mounting point are shortened, that is, the influence of the dimensional tolerance of the mounting plate on the assembly of A-light is reduced, and the matching accuracy of DTS (gap, surface difference, alignment) is improved by setting two positioning points, thereby improving product quality.

[0023] Thirdly, this utility model provides a vehicle including the rear body structure provided in any of the embodiments of the second aspect above.

[0024] The vehicle provided in this utility model embodiment includes the rear body structure provided in any of the embodiments of the second aspect above, and therefore has the same technical effect.

[0041] In related technologies, as basic automotive functions are met, consumers are increasingly demanding more refined car exteriors, especially the rear area, which directly impacts customer perception of the vehicle. The A-light, as a finishing touch to the rear design, is particularly sensitive to gaps, surface differences, and alignment in the exterior design. The A-light area involves complex component matching and numerous dimensional links, leading to accumulated tolerances. This has made the DTS (gap, surface difference, alignment) issues between the A-light and the side panels and B-light a persistent pain point for various car models.

[0042] In view of this, the present invention provides an A-lamp assembly structure that reduces the final installation position deviation of the A-lamp caused by the accumulated tolerance of intermediate parts, improves assembly consistency, and enhances the matching accuracy of DTS (gap, surface difference, alignment).

[0043] It should be noted that the vehicles or automobiles mentioned in this utility model can refer to large automobiles, small automobiles, special-purpose vehicles, etc. For example, according to the vehicle type, the vehicles or automobiles in this utility model can be sedans, off-road vehicles, multi-purpose vehicles (MPVs), or other types of vehicles.

[0044] The following is for reference. Figures 1-4 A lamp assembly structure 100 according to an embodiment of the present utility model is described, including: lamp 1, mounting plate 2 and mounting supplement plate 3.

[0045] Specifically, lamp A1 has a first positioning part 11 and a second positioning part 12. A first mating positioning part 21 is formed on the mounting plate 2. The first positioning part 11 and the first mating positioning part 21 cooperate to limit the relative position of lamp A1 and mounting plate 2 in the X and Z directions. Mounting supplement plate 3 is connected to mounting plate 2. A second mating positioning part 31 is formed on mounting supplement plate 3. The second positioning part 12 and the second mating positioning part 31 cooperate to limit the relative position of lamp A1 and mounting supplement plate 3 in the Y and Z directions. Thus, by forming a second mating positioning part 31 on mounting supplement plate 3 that mates with the second positioning part 12, the final installation position deviation of lamp A1 caused by the accumulated tolerance of intermediate parts is reduced, the assembly consistency is improved, and the dimensional links of the mounting point of lamp A1 in the X, Y, and Z directions are shortened. That is, the dimensional tolerance of mounting plate 2 on lamp A1 is reduced, and the matching accuracy of DTS (gap, surface difference, alignment) is improved by setting two positioning points, thereby improving product quality.

[0046] Understandably, referring to Figure 1 and Figure 2 As shown, lamp A1 has a first positioning part 11 for engaging with a first mating positioning part 21 on the mounting plate 2. Lamp A1 also has a second positioning part 12 for engaging with a second mating positioning part 31 on the mounting supplement plate 3. The mounting plate 2 has a first mating positioning part 21, which forms constraints in the X and Z directions with the first positioning part 11 of lamp A1. The mounting supplement plate 3 is connected to the mounting plate 2 and has a second mating positioning part 31, which engages with the second positioning part 12 of lamp A1, thus achieving constraints in the Y and Z directions and improving the matching accuracy of DTS (gap, surface difference, alignment).

[0047] According to the A-lamp assembly structure 100 of this utility model embodiment, by forming a second mating positioning part 31 on the mounting supplement plate 3 that mates with the second positioning part 12, the final installation position deviation of A-lamp 1 caused by the accumulated tolerance of intermediate parts is reduced, the assembly consistency is improved, and the X, Y, and Z dimensional links of the A-lamp 1 mounting point are shortened, that is, the dimensional tolerance of the mounting plate 2 is reduced on the assembly of A-lamp 1, etc. By setting two positioning points, the matching accuracy of DTS (gap, surface difference, alignment) is improved, thereby improving product quality.

[0048] In some embodiments of this utility model, one of the first mating positioning part 21 and the first positioning part 11 is formed as a positioning hole, and the other of the first mating positioning part 21 and the first positioning part 11 is formed as a positioning pin. The positioning pin extends into the positioning hole to position lamp A1 in the X and Z directions. Thus, by setting the first mating positioning part 21 and the first positioning part 11 to cooperate, the positional constraint between lamp A1 and the mounting plate 2 is realized, the matching accuracy of DTS (gap, surface difference, alignment) is improved, the dimensional chain of the mounting point of lamp A1 in the X and Z directions is shortened, and the cooperation between the positioning pin and the positioning hole can increase the assembly stress and improve the structural stability of the connection between lamp A1 and the mounting plate 2.

[0049] Reference Figure 1 and Figure 2 As shown, the first positioning part 11 is formed as a positioning pin extending along the X direction, and the first mating positioning part 21 is formed as a circular positioning hole. The positioning pin extends into the positioning hole to restrict the assembly position in the X and Z directions. Specifically, when the positioning pin is fully inserted into the positioning hole, the end face of the positioning pin or the bottom of the positioning hole contacts each other, restricting the movement of lamp A 1 in the X direction (up and down). The radial fit between the positioning pin and the positioning hole (i.e., the hole wall of the positioning hole contacts the outer peripheral wall of the positioning pin) restricts the movement of lamp A 1 in the Z direction (left and right).

[0050] In other embodiments, the first positioning part 11 may be formed as a positioning hole, and the first mating positioning part 21 may be formed as a positioning pin.

[0051] In some embodiments of this utility model, one of the second mating positioning part 31 and the second positioning part 12 is formed as a positioning hole, and the other of the second mating positioning part 31 and the second positioning part 12 is formed as a positioning pin. The positioning pin extends into the positioning hole to position lamp A1 in the Y and Z directions. Thus, by setting the second mating positioning part 31 and the second positioning part 12 to cooperate, the positional constraint between lamp A1 and the mounting plate 3 is realized, the matching accuracy of DTS (gap, surface difference, alignment) is improved, the dimensional chain of the mounting point of lamp A1 in the Y and Z directions is shortened, and the cooperation between the positioning pin and the positioning hole can increase the assembly stress and improve the structural stability of the connection between lamp A1 and the mounting plate 3.

[0052] Reference Figure 1 and Figure 2As shown, the second positioning part 12 is formed as a positioning pin extending along the Z direction, and the second mating positioning part 31 is formed as a square positioning hole. The positioning pin extends into the positioning hole to restrict the assembly position in the Y and Z directions. Specifically, when the positioning pin is fully inserted into the positioning hole, the positioning pin forms a limiting groove 16. The periphery of the positioning hole of the mounting plate 2 is located in the limiting groove 16 to prevent the movement of lamp A 1 in the Z direction. The radial mating between the positioning pin and the positioning hole (i.e., the hole wall of the positioning hole contacts the outer peripheral wall of the positioning pin) restricts the movement of lamp A 1 in the Y direction.

[0053] In other embodiments, the second positioning part 12 may be formed as a positioning hole, and the second mating positioning part 31 may be formed as a positioning pin.

[0054] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the A-lamp assembly structure 100 also includes: a side outer plate 4, on which a third mating positioning part 41 is formed; the A-lamp 1 has a third positioning part 13, which mates with the third mating positioning part 41 to limit the relative position of the A-lamp 1 and the side outer plate 4 in the X and Y directions. Thus, by forming the third mating positioning part 41 on the side outer plate 4 that mates with the third positioning part 13, the final installation position deviation of the A-lamp 1 caused by the accumulated tolerances of intermediate parts is reduced, improving assembly consistency and shortening the Y and X dimensional links of the A-lamp 1 installation point. This reduces the impact of the dimensional tolerances of the mounting plate 2 on the assembly of the A-lamp, etc. Furthermore, by setting three positioning points, the matching accuracy of the DTS (gap, surface difference, alignment) is improved, further enhancing product quality.

[0055] In some embodiments of this utility model, one of the third mating positioning part 41 and the third positioning part 13 is formed as a positioning hole, and the other of the third mating positioning part 41 and the third positioning part 13 is formed as a positioning pin. The positioning pin extends into the positioning hole to position lamp A1 in the X and Y directions. Thus, by setting the third mating positioning part 41 and the third positioning part 13 to cooperate, the positional constraint between lamp A1 and the side outer panel 4 is realized, the matching accuracy of DTS (gap, surface difference, alignment) is improved, the dimensional chain of the mounting point of lamp A1 in the Y and X directions is shortened, and the cooperation between the positioning pin and the positioning hole can increase the assembly stress and improve the structural stability of the connection between lamp A1 and the side outer panel 4.

[0056] Reference Figure 1 and Figure 2As shown, the third positioning part 13 is formed as a positioning pin extending along the Y direction, and the third mating positioning part 41 is formed as a square positioning hole. The positioning pin extends into the positioning hole to restrict the assembly position in the X and Y directions. Specifically, when the positioning pin is fully inserted into the positioning hole, the end face of the positioning pin or the bottom of the positioning hole contacts each other, restricting the movement of lamp A 1 in the Y direction. The radial fit between the positioning pin and the positioning hole (i.e., the hole wall of the positioning hole contacts the outer peripheral wall of the positioning pin) restricts the movement of lamp A 1 in the X direction.

[0057] In other embodiments, the third positioning part 13 may be formed as a positioning hole, and the third mating positioning part 41 may be formed as a positioning pin.

[0058] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the outer side panel 4 has a first mating surface 42, and the A-lamp 1 has a second mating surface 14. The first mating surface 42 and the second mating surface 14 are in contact. Thus, by setting the first mating surface 42 and the second mating surface 14, a gap between the A-lamp 1 and the outer side panel 4 is avoided, tolerance compensation improves assembly tolerance, enhances sealing and protective performance, and improves the appearance quality of the vehicle.

[0059] In some embodiments of this utility model, a first mounting portion 22 is formed on the mounting plate 2, and a second mounting portion 15 is formed on the A lamp 1. The mounting plate 2 and the A lamp 1 are mounted together through the cooperation of the first mounting portion 22 and the second mounting portion 15. It can be understood that by setting the first mounting portion 22 and the second mounting portion 15 to cooperate, the functions of positioning and connection are decoupled, the connection stability between the A lamp 1 and the mounting plate 2 is improved, thereby ensuring the long-term stability of the appearance matching.

[0060] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the first mounting part 22 is formed as a first mounting hole, and the second mounting part 15 is formed as a second mounting hole. The first mounting hole and the second mounting hole are arranged in a one-to-one correspondence and connected by fasteners. Therefore, the connection and fixing method using fasteners is simple, and the connection strength and reliability are high, making it easy to disassemble, assemble, and maintain.

[0061] In some embodiments of this utility model, a fourth mating positioning part 23 is formed on the mounting plate 2, and a fourth positioning part 17 is formed on lamp A 1. The fourth positioning part 17 and the fourth mating positioning part 23 cooperate to limit the relative position of lamp A 1 and mounting plate 2 in the Y direction. Thus, by forming the fourth mating positioning part 23 on the mounting plate 2 that cooperates with the fourth positioning part 17, the final installation position deviation of lamp A 1 caused by the accumulated tolerance of intermediate parts is reduced, the assembly consistency is improved, the Y-direction dimensional chain of the mounting point of lamp A 1 is shortened, that is, the dimensional tolerance of the mounting plate 2 is reduced on the assembly of lamp A 1, etc., and the matching accuracy of DTS (gap, surface difference, alignment) is improved by setting four positioning points, further improving product quality.

[0062] In some embodiments of this utility model, one of the fourth mating positioning part 23 and the fourth positioning part 17 is formed as a positioning hole, and the other of the fourth mating positioning part 23 and the fourth positioning part 17 is formed as a positioning pin. The positioning pin extends into the positioning hole to position lamp A1 in the Y direction. Thus, by setting the fourth mating positioning part 23 and the fourth positioning part 17 to cooperate, the positional constraint between lamp A1 and the mounting plate 2 is realized, the matching accuracy of DTS (gap, surface difference, alignment) is improved, the dimensional chain in the Y direction of the mounting point of lamp A1 is shortened, and the cooperation between the positioning pin and the positioning hole can increase the assembly stress and improve the structural stability of the connection between lamp A1 and the mounting plate 2.

[0063] Reference Figure 1 and Figure 2 As shown, the fourth positioning part 17 is formed as a positioning pin extending in the X direction, and the fourth mating positioning part 23 is formed as a circular positioning hole. The positioning pin extends into the positioning hole to restrict the assembly position in the Y direction. Specifically, when the positioning pin is fully inserted into the positioning hole, the end face of the positioning pin or the bottom of the positioning hole contacts each other, restricting the movement of lamp A 1 in the Y direction. The radial fit between the positioning pin and the positioning hole (i.e., the hole wall of the positioning hole contacts the outer peripheral wall of the positioning pin) restricts the movement of lamp A 1 in the Y direction.

[0064] In other embodiments, the fourth positioning part 17 may be formed as a positioning hole, and the fourth mating positioning part 23 may be formed as a positioning pin.

[0065] The following reference Figures 1-4 The assembly structure 100 of lamp A according to a specific embodiment of the present invention will be described.

[0066] like Figure 1 and Figure 2 As shown, the A-lamp assembly structure 100 includes: A-lamp 1, mounting plate 2, mounting supplement plate 3, and side panel 4.

[0067] Lamp A1 has a first positioning part 11 for engaging with a first mating positioning part 21 on the mounting plate 2.

The Z-direction gap dimension tolerance between the side outer plate 4 and the positioning hole of lamp A1 satisfies the following: the Z-direction surface profile tolerance between the side outer plate 4 and lamp A1 is ±0.25mm, the Z-direction welding surface profile tolerance between the side outer plate 4 and the mounting patch plate 3 is ±0.25mm, the Z-direction welding surface profile tolerance between the mounting patch plate 3 and the side outer plate 4 is ±0.25mm, and the Z-direction main positioning surface profile tolerance between the mounting patch plate 3 and lamp A1 is ±0.25mm.
