[0002] With the development of the automotive industry, consumers have increasingly higher demands for the aesthetics and technological sophistication of vehicle exterior design. Traditional exposed taillights require separate sections in the overall vehicle design, affecting the integrated design of the entire vehicle. In recent years, concealed taillights, due to their high degree of integration with the overall vehicle design when not illuminated, have gradually become a design trend for high-end models. However, the current installation structure of concealed taillights needs optimization. Utility Model Content

[0003] This application provides a taillight mounting structure and a vehicle for optimizing the taillight mounting structure.

[0004] According to one aspect of this application, a taillight mounting structure is provided, including a mounting bracket, a lamp housing, and a positioning structure. The lamp housing is assembled with the mounting bracket, and the positioning structure restricts the relative movement of the lamp housing and the mounting bracket along a first direction, a second direction, and a third direction. The positioning structure includes a first positioning post and a first positioning groove. One of the first positioning post and the first positioning groove is disposed on the mounting bracket, and the other is disposed on the lamp housing. The first positioning post can enter the first positioning groove along a fourth direction and cooperates with the first positioning groove to restrict the movement of the lamp housing and the mounting bracket along the second direction. The first direction, the second direction, and the third direction intersect each other, and the fourth direction intersects with the third direction.

[0005] In some embodiments, the first positioning groove includes a first sub-positioning groove extending along the fourth direction and a second sub-positioning groove extending along the third direction, wherein the first positioning post can enter the second sub-positioning groove through the first sub-positioning groove and cooperate with the second sub-positioning groove to restrict the movement of the lamp housing and the mounting bracket along the second direction.

[0006] In some embodiments, the angle between the fourth direction and the third direction is not a right angle.

[0007] In some embodiments, the positioning structure includes a plurality of first positioning posts and a plurality of first positioning slots, each of the first positioning posts being positioned and engaged with a different first positioning slot.

[0008] In some embodiments, the first positioning post is disposed on the lamp housing, and a limiting rib is provided at the end of the first positioning post away from the lamp housing; when the first positioning post is positioned and engaged with the first positioning groove, the limiting rib engages with the lamp housing to restrict the movement of the lamp housing and the mounting bracket along the first direction.

[0009] In some embodiments, the positioning structure further includes a second positioning post and a second positioning hole, one of which is disposed on the mounting bracket and the other is disposed on the lamp housing; the second positioning post extends along the third direction, the dimension of the second positioning hole along the first direction is adapted to the dimension of the second positioning post along the first direction, and the dimension of the second positioning hole along the second direction is greater than the dimension of the second positioning post along the second direction.

[0010] In some embodiments, the positioning structure further includes a snap-fit ​​element having a plurality of snap-fit ​​slots arranged along the third direction, wherein the lamp housing and the mounting bracket are respectively snap-fitted and adapted to different snap-fit ​​slots.

[0011] In some embodiments, the taillight mounting structure further includes a fixing structure, the fixing structure including a first mounting hole and a first fixing member; both the lamp housing and the mounting bracket are provided with the first mounting hole, the first fixing member is inserted into the first mounting hole of the lamp housing and the first mounting hole of the mounting bracket along the first direction, and fixes the lamp housing and the mounting bracket.

[0012] In some embodiments, the taillight mounting structure further includes a fixing structure, which includes a second mounting hole and a second fixing member; both the lamp housing and the mounting bracket are provided with the second mounting hole, and the second fixing member is inserted into the second mounting hole of the lamp housing and the second mounting hole of the mounting bracket along the third direction, thereby fixing the lamp housing and the mounting bracket.

[0013] According to another aspect of this application, a vehicle is provided, including the taillight mounting structure as described above.

[0014] The taillight mounting structure of this application embodiment restricts the relative movement of the lamp housing and the mounting bracket in three intersecting directions by setting a positioning structure, making the positioning of the lamp housing in three-dimensional space more precise. Furthermore, the positioning structure includes a first positioning post and a first positioning groove, and the direction in which the first positioning post enters the first positioning groove intersects with the positioning direction of the lamp housing by the first positioning post; that is, the installation direction of the lamp housing intersects with the positioning direction. Thus, when the first positioning post and the first positioning groove are in positional engagement, the lamp housing needs to move a preset distance along two intersecting directions to detach from the mounting bracket, improving the accuracy and stability of the lamp housing installation and reducing the space required for lamp housing installation and removal in a single direction.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0028] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0029] In related technologies, taillights are usually mounted in the X direction or near the X direction, where the X direction is the front-to-back direction of the vehicle body. This mounting method limits the installation path and makes it impossible to mount the taillights on the underside of the sheet metal, thus failing to achieve a hidden effect.

[0030] Changing the installation direction of the taillights would lead to difficulties in installation and disassembly, thus affecting production cycle time and maintenance efficiency. If the goal is to facilitate installation and disassembly while changing the taillight installation direction, the relevant installation structure needs to be modified to reduce constraints, resulting in low installation accuracy and poor consistency in mass production.

[0031] To address the aforementioned issues, this application provides a taillight mounting structure that solves the installation problem of concealed taillights mounted on the underside of sheet metal. While ensuring installation feasibility, it also considers installation accuracy, ease of operation, and convenience of subsequent disassembly and maintenance.

[0032] See Figures 1-3In some embodiments, the taillight mounting structure 1 includes a mounting bracket 10, a lamp housing 20, and a positioning structure. The lamp housing 20 is assembled with the mounting bracket 10, and the positioning structure plays a positioning role between the lamp housing 20 and the mounting bracket 10. The mounting bracket 10 is, for example, a sheet metal part mounted on the vehicle body 2. The lamp housing 20 is provided with a receiving cavity for accommodating the light source. The material of the lamp housing 20 is, for example, at least one of polymethyl methacrylate (PMMA), ASA plastic (a synthetic resin made by graft copolymerization of styrene, acrylonitrile, and acrylate rubbers), polypropylene (PP), and engineering plastic alloy (PC+ABS).

[0033] The positioning structure restricts the relative movement of the lamp housing 20 and the mounting bracket 10 along the first direction D1, the second direction D2, and the third direction D3. The first direction D1, the second direction D2, and the third direction D3 intersect each other; for example, the first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other or form an acute angle. In this way, the lamp housing 20 can be accurately positioned in three-dimensional space.

[0034] Combined Figure 4 and Figure 5 The positioning structure includes a first positioning post 31 and a first positioning groove 32. One of the first positioning post 31 and the first positioning groove 32 is disposed on the mounting bracket 10, and the other is disposed on the lamp housing 20. For example, the first positioning post 31 is disposed on the lamp housing 20, and the first positioning groove 32 is disposed on the mounting bracket 10; or, the first positioning post 31 is disposed on the mounting bracket 10, and the first positioning groove 32 is disposed on the lamp housing 20. The first positioning post 31 can enter the first positioning groove 32 along the fourth direction D4, and cooperate with the first positioning groove 32 to restrict the movement of the lamp housing 20 and the mounting bracket 10 along the second direction D2. The fourth direction D4 intersects with the third direction D3, for example, the fourth direction D4 is perpendicular to the third direction D3 or the included angle is an acute angle. Based on this, the installation direction of the lamp housing 20 intersects with the positioning direction. Thus, when the first positioning post 31 and the first positioning groove 32 are positioned and engaged, the lamp housing 20 needs to move a preset distance along the two intersecting directions to detach from the mounting bracket 10. This improves the accuracy and stability of the lamp housing 20 installation and reduces the space required for the lamp housing 20 to be disassembled and installed in a single direction.

[0035] In some embodiments, the first positioning groove 32 includes a first sub-positioning groove 321 extending along the fourth direction D4 and a second sub-positioning groove 322 extending along the third direction D3. The first positioning post 31 can enter the second sub-positioning groove 322 through the first sub-positioning groove 321 and cooperate with the second sub-positioning groove 322 to restrict the movement of the lamp housing 20 and the mounting bracket 10 along the second direction D2. Thus, during the assembly of the lamp housing 20 and the mounting bracket 10, the first sub-positioning groove 321 and the second sub-positioning groove 322 provide assembly guidance for the first positioning post 31. The first positioning post 31 first passes through the first sub-positioning groove 321 and then enters the second sub-positioning groove 322. The two opposite groove walls of the second sub-positioning groove 322 along the second direction D2 play a positioning role for the first positioning post 31. When the second direction D2 is not parallel to the horizontal direction, for example, when the second direction D2 is perpendicular to the horizontal direction or inclined relative to the horizontal direction, the lower groove wall can also support the first positioning post 31, improving the accuracy and stability of the installation. Furthermore, since the positioning structure is relatively simple overall, it also improves the convenience of assembly operation and the ease of disassembly and maintenance in the later stage.

[0036] Optionally, a rounded corner is provided at the junction between the first sub-positioning groove 321 and the second sub-positioning groove 322, so that the first positioning post 31 can move more smoothly in the first sub-positioning groove 321 and the second sub-positioning groove 322, thereby making the disassembly and assembly of the lamp housing 20 smoother.

[0037] In some embodiments, the angle between the fourth direction D4 and the third direction D3 is not a right angle. For example, the angle between the fourth direction D4 and the third direction D3 is 120°, 135°, or 150°. Exemplarily, when the taillight mounting structure 1 is located on the vehicle body 2, the first direction D1 is parallel to the front-rear direction of the vehicle body 2, the second direction D2 is parallel to the height direction of the vehicle body 2, the third direction D3 is parallel to the left-right direction of the vehicle body 2, and the fourth direction D4 is inclined upwards. Based on this, during the installation process of the lamp housing 20 and the mounting bracket 10, the first sub-positioning groove 321 and the second sub-positioning groove 322 provide assembly guidance for the first positioning post 31, causing the first positioning post 31 to first move inclined upwards, and then move horizontally to the left or right, reducing the space required for the lamp housing 20 to be assembled in the left-right direction, thus reducing the loss of overall lamp space caused by left-right assembly.

[0038] In some embodiments, the positioning structure includes a plurality of first positioning posts 31 and a plurality of first positioning slots 32, with each first positioning post 31 engaging with a different first positioning slot 32. Optionally, the plurality of first positioning posts 31 correspond one-to-one with the plurality of first positioning slots 32, thereby saving space while maintaining positioning accuracy. Optionally, the plurality of first positioning posts 31 may be at the same or different positions along the second direction D2; for example, when the second direction D2 is parallel to the height direction of the vehicle body 2, the heights of the plurality of first positioning posts 31 may be the same or different. In an exemplary embodiment, the positioning structure includes two first positioning posts 31 and two first positioning slots 32, with the two first positioning posts 31 having the same height. Based on this, the multiple sets of first positioning posts 31 and first positioning slots 32 engage in positioning, which can further improve assembly accuracy and stability.

[0039] See Figures 4-6 In some embodiments, a first positioning post 31 is disposed on the lamp housing 20, and a limiting rib 311 is provided at the end of the first positioning post 31 away from the lamp housing 20. When the first positioning post 31 is positioned and engaged with the first positioning groove 32, the limiting rib 311 engages with the lamp housing 20 to restrict the movement of the lamp housing 20 relative to the mounting bracket 10 along the first direction D1. Thus, the positioning structure is simple and easy to form.

[0040] Optionally, the first positioning post 31 is cylindrical, and the limiting rib 311 is provided at one end of the first positioning post 31 along the axial direction. The limiting rib 311 is provided in a radial direction relative to the surface of the first positioning post 31. In this way, the recess formed by the combination of the lamp housing 20, the first positioning post 31, and the limiting rib 311 can be positioned and engaged with the corresponding part of the mounting bracket 10, so that the lamp housing 20 and the mounting bracket 10 are relatively fixed or have a small movable space in the first direction D1.

[0041] Optionally, the first positioning post 31 is constructed as a hollow columnar structure, thereby reducing material, lowering costs, and reducing the weight of the lamp housing 20.

[0042] Optionally, the shape of the limiting rib 311 can be semi-circular, triangular, quadrilateral, pentagonal, hexagonal, or a combination thereof, and the specific shape can be flexibly adjusted according to design requirements.

[0043] Optionally, the ratio of the dimension of the limiting rib 311 along the first direction D1 to the dimension of the first positioning post 31 along the first direction D1 is 1 / 3 to 2 / 3. For example, the ratio of the dimension of the limiting rib 311 along the first direction D1 to the dimension of the first positioning post 31 along the first direction D1 is 1 / 2. In this way, the dimension of the limiting rib 311 along the first direction D1 is larger, the structural strength is greater, and it is not easily damaged.

[0044] Continue reading Figures 4-6Optionally, the limiting rib 311 includes a first limiting portion 3111 and a second limiting portion 3112 arranged circumferentially along the first positioning post 31, and a connecting portion 3113 connecting the first limiting portion 3111 and the second limiting portion 3112. In this way, the first limiting portion 3111 and the second limiting portion 3112 cooperate to limit the position, increasing the area of ​​the limiting rib 311 relative to the mounting bracket 10, thereby improving the limiting stability.

[0045] Optionally, the limiting rib 311 is integrally formed with the first positioning post 31, thereby improving the structural strength.

[0046] See Figure 3 In some embodiments, the positioning structure further includes a second positioning post 33 and a second positioning hole 34, one of which is disposed on the mounting bracket 10 and the other on the lamp housing 20. Exemplarily, the second positioning post 33 is disposed on the lamp housing 20, and the second positioning hole 34 is disposed on the mounting bracket 10. The second positioning post 33 extends along a third direction D3, the size of the second positioning hole 34 along a first direction D1 is adapted to the size of the second positioning post 33 along the first direction D1, and the size of the second positioning hole 34 along a second direction D2 is larger than the size of the second positioning post 33 along the second direction D2. For example, the second positioning hole 34 is constructed as an oblong hole. Thus, the second positioning post 33 can more easily enter the second positioning hole 34, while simultaneously cooperating with the second positioning hole 34 to restrict the movement of the lamp housing 20 along the first direction D1.

[0047] It should be noted that the dimensions of the second positioning hole 34 and the second positioning post 33 along the first direction D1 can be equal or unequal. When the dimension of the second positioning hole 34 along the first direction D1 is less than or equal to the dimension of the second positioning post 33 along the first direction D1, for example, in the case of an interference fit, the assembly stability between the lamp housing 20 and the mounting bracket 10 can be improved. When the dimension of the second positioning hole 34 along the first direction D1 is greater than the dimension of the second positioning post 33 along the first direction D1, the assembly between the lamp housing 20 and the mounting bracket 10 can be made more convenient and faster.

[0048] It should also be noted that the dimension of the second positioning post 33 along the third direction D3 must be smaller than the dimension of the first positioning groove 32 along the third direction D3. In this way, the distance along the third direction D3 required for the first positioning post 31 to move from the entrance of the first positioning groove 32 to the end of the first positioning groove 32 is greater than the distance required for the second positioning post 33 to enter the second limiting groove, thereby avoiding interference between the first positioning post 31 and the positioning of the second positioning post 33.

[0049] Optionally, the second positioning post 33 is provided with multiple reinforcing ribs at circumferential intervals to improve structural strength.

[0050] Optionally, the second positioning post 33 is integrally formed with the lamp housing 20, thereby improving the structural strength.

[0051] See Figure 3 , Figure 7 and Figure 8 In some embodiments, the positioning structure further includes a snap-fit ​​element 35. The snap-fit ​​element 35 is made of, for example, plastic. On the one hand, the plastic snap-fit ​​element 35 can undergo elastic deformation and recover its shape during the snap-fit ​​process, which facilitates smooth snap-fit ​​completion and improves snap-fit ​​stability; on the other hand, plastic is relatively lightweight, thereby reducing the overall weight. The snap-fit ​​element 35 has multiple snap-fit ​​slots 351 arranged along a third direction D3, and the lamp housing 20 and the mounting bracket 10 are respectively snapped into and adapted to different snap-fit ​​slots 351. Thus, the lamp housing 20 and the mounting bracket 10 are positioned in the third direction D3 through the snap-fit ​​element 35.

[0052] Optionally, there are two snap-fit ​​slots 351, with the lamp housing 20 and mounting bracket 10 snapping into the two snap-fit ​​slots 351 respectively. In this way, the snap-fit ​​component 35 has a simple structure and low cost.

[0053] Optionally, the number of snap-fit ​​slots 351 is greater than two, and each snap-fit ​​slot 351 snaps into the lamp housing 20 or the mounting bracket 10, thereby improving the installation stability of the lamp housing 20 and the mounting bracket 10.

[0054] Further integration Figure 9 and Figure 10 Optionally, the mounting bracket 10 is provided with a first ear plate 11, and the lamp housing 20 is provided with a second ear plate 21. The shape of the first ear plate 11 is the same as or different from that of the second ear plate 21. The first ear plate 11 and the second ear plate 21 are respectively engaged with different engaging slots 351 on the engaging member 35 to achieve the limiting of the lamp housing 20 and the mounting bracket 10 in the third direction D3.

[0055] Optionally, both the first ear plate 11 and the second ear plate 21 extend along a first direction D1. The first ear plate 11 has a through hole 12, which penetrates the first ear plate 11 along a third direction D3. The second ear plate 21 has a groove 22, which penetrates the second ear plate 21 along a third direction D3, and the opening of the groove 22 faces the side away from the lamp housing 20. The snap-fit ​​component 35 includes a snap-fit ​​post 352, a first baffle 353, a second baffle 354, and a snap-fit ​​connector 355. The first baffle 353, the second baffle 354, and the snap-fit ​​connector 355 are arranged sequentially along the axial direction of the snap-fit ​​post 352. A snap-fit ​​groove 351 is formed between the first baffle 353 and the second baffle 354, and another snap-fit ​​groove 351 is formed between the second baffle 354 and the snap-fit ​​connector 355.

[0056] Based on this, the snap-fit ​​connector 355 is inserted into the groove 22 of the second ear plate 21 through the slot, so that the second ear plate 21 enters the snap-fit ​​groove 351 between the first baffle 353 and the second baffle 354, thereby achieving snap-fit ​​between the snap-fit ​​member 35 and the lamp housing 20. When the lamp housing 20 is snapped with the snap-fit ​​member 35, the snap-fit ​​post 352 passes through the groove 22 of the second ear plate 21, and the second ear plate 21 is located in the snap-fit ​​groove 351 formed by the first baffle 353 and the second baffle 354 and cannot move axially along the snap-fit ​​member 35. The snap-fit ​​connector 355 is inserted into the through hole 12 of the first ear plate 11 along the third direction D3, so that the first ear plate 11 enters the snap-fit ​​groove 351 between the snap-fit ​​connector 355 and the second baffle 354, thereby achieving snap-fit ​​between the snap-fit ​​member 35 and the mounting bracket 10. When the mounting bracket 10 is engaged with the snap-fit ​​connector 35, the snap-fit ​​post 352 passes through the through hole 12 of the first ear plate 11, and the first ear plate 11 is located within the snap-fit ​​groove 351 formed by the second baffle 354 and the snap-fit ​​connector 355, and cannot move axially along the snap-fit ​​connector 35. In this way, the snap-fit ​​connector 35 can limit the position of the lamp housing 20 and the mounting bracket 10 in the third direction D3, and also provide pre-installation snap-fit ​​force for the entire lamp.

[0057] It should be noted that the dimension of the snap-fit ​​connector 355 along the third direction D3 must be smaller than the dimension of the first positioning groove 32 along the third direction D3. In this way, the distance along the third direction D3 required for the first positioning post 31 to move from the entrance of the first positioning groove 32 to the end of the first positioning groove 32 is greater than the distance required for the snap-fit ​​connector 355 to be snapped into place, thereby avoiding interference of the first positioning post 31 with the snap-fit ​​connector 355.

[0058] Optionally, the end of the snap-fit ​​connector 355 away from the second baffle 354 is tapered, and the radial dimension of the end of the snap-fit ​​connector 355 away from the second baffle 354 is smaller than the radial dimension of the end of the snap-fit ​​connector 355 near the second baffle 354. This allows the snap-fit ​​connector 355 to be inserted more smoothly into the through hole 12 of the first ear plate 11.

[0059] Optionally, a reinforcing rib is provided between the second ear plate 21 and the lamp housing 20 to improve the structural strength of the second ear plate 21.

[0060] Optionally, a plurality of reinforcing ribs are provided between the second ear plate 21 and the lamp housing 20, and the plurality of reinforcing ribs are arranged at intervals along the second direction D2, thereby further improving the structural strength.

[0061] Optionally, a plurality of reinforcing ribs are provided between the second ear plate 21 and the lamp housing 20, some of which are located on one side of the second ear plate 21 along the third direction D3, and other of which are located on the other side of the second ear plate 21 along the third direction D3, thereby further improving the structural strength.

[0062] See Figure 3 , Figure 4 and Figure 8 In some embodiments, the taillight mounting structure 1 further includes a fixing structure, which includes a first mounting hole 41 and a first fixing member 42. The first fixing member 42 includes, for example, a bolt and a nut matching the bolt. The type of bolt and nut can be selected according to design requirements and is not limited here. Optionally, the number of first mounting holes 41 and the number of first fixing members 42 can be one or more, and the number of first mounting holes 41 is equal to the number of first fixing members 42. For example, the number of first mounting holes 41 and first fixing members 42 are both two, and the two first mounting holes 41 are arranged at intervals along a third direction D3.

[0063] Furthermore, both the lamp housing 20 and the mounting bracket 10 are provided with a first mounting hole 41. The first fixing member 42 is inserted into the first mounting hole 41 of the lamp housing 20 and the first mounting hole 41 of the mounting bracket 10 along the first direction D1, and fixes the lamp housing 20 and the mounting bracket 10. In this way, based on the precise positioning of the positioning structure, the lamp housing 20 and the mounting bracket 10 are fixed by the fixing structure, so that the lamp housing 20 remains stable.

[0064] Continue reading Figure 3 and Figure 4 In some embodiments, the taillight mounting structure 1 further includes a fixing structure, which includes a second mounting hole 43 and a second fixing member 44. The second fixing member 44 includes, for example, a bolt and a nut that matches the bolt. The type of bolt and nut can be selected according to design requirements and is not limited here. Both the lamp housing 20 and the mounting bracket 10 are provided with a second mounting hole 43. The second fixing member 44 is inserted into the second mounting hole 43 of the lamp housing 20 and the second mounting hole 43 of the mounting bracket 10 along the third direction D3, and fixes the lamp housing 20 and the mounting bracket 10. Based on this, by adjusting the nut, the mounting position of the lamp housing 20 in the third direction D3 can be finely adjusted, and then the bolt in the first direction D1 can be tightened to meet the gap surface difference requirements.

[0065] See Figures 1-10 In one exemplary embodiment, the taillight mounting structure 1 includes a mounting bracket 10, a lamp housing 20, a positioning structure, and a fixing structure. The mounting bracket 10 is a sheet metal that can be mounted on the vehicle body 2. The front-to-back direction of the vehicle body 2 is a first direction D1, the vertical direction of the vehicle body 2 is a second direction D2, and the left-to-right direction of the vehicle body 2 is a third direction D3.

[0066] The positioning structure includes a first positioning post 31, a first positioning groove 32, a second positioning post 33, a second positioning hole 34, and a snap-fit ​​component 35. The first positioning post 31 and the second positioning post 33 are located on the lamp housing 20; for example, the first positioning post 31 and the second positioning post 33 are integrally formed with the lamp housing 20. The first positioning groove 32 and the second positioning hole 34 are located on the mounting bracket 10. The snap-fit ​​component 35 is a separate structure from the lamp housing 20, and also a separate structure from the mounting bracket 10.

[0067] The number of first positioning posts 31 and the number of first positioning slots 32 are both two, with each first positioning post 31 corresponding to one of the two first positioning slots 32. Both first positioning posts 31 extend along a first direction D1 and are spaced apart along a third direction D3.
