[0028] Please also refer to Figures 1 to 7 The light-emitting unit positioning and mounting structure and vehicle provided by the present invention are now described. The light-emitting unit positioning and mounting structure comprises a light-transmitting skin 1, a positioning seat, a light-emitting unit 3, and a supporting frame 4, which are arranged in sequence. A plurality of positioning seats are provided, each connected to the rear side of the light-transmitting skin 1. The light-emitting unit 3 is provided with a positioning platform that plugs into and connects to the positioning seat in a one-to-one correspondence. The light-emitting unit 3 is connected to the front side of the supporting frame 4. The upper and lower edges of the light-transmitting skin 1 extend rearward and are connected to the supporting frame 4.

[0029] The light-emitting unit positioning and installation structure provided in the present embodiment is compared with the prior art. The light-emitting unit positioning and installation structure provided in the present embodiment utilizes the positioning seat on the translucent skin 1 and the positioning platform of the light-emitting unit 3 to perform precise positioning and connection. The light-emitting unit 3 and the translucent skin 1 are respectively connected to the load-bearing frame 4. The load-bearing frame 4 can effectively disperse the load formed by the light-emitting unit 3 and the translucent skin 1 to the vehicle body, thereby improving the structural stability of the installation of the light-emitting unit 3, avoiding loosening or displacement of the light-emitting unit 3 due to road bumps during vehicle driving, improving the reliability of the structural installation, and facilitating subsequent maintenance or replacement.

[0030] In this embodiment, the translucent skin 1, the positioning seat, the light-emitting unit 3, and the supporting frame 4 are arranged in sequence from the front side to the rear side of the vehicle body. The supporting frame 4 can be reliably connected to structures such as the front anti-collision beam, the upper crossbeam sheet metal, and the lower support plate, and can structurally support and install the light-emitting unit 3 and the translucent skin 1 on the front side of the supporting frame 4. The light-emitting unit 3 is mutually positioned with the translucent skin 1 through the positioning seat, so that the relative position of the translucent skin 1 and the light-emitting unit 3 is effectively defined. The supporting frame 4 is located on the rear side of the light-emitting unit 3 and is respectively connected to the skin assembly and the light-emitting unit 3, so that the translucent skin 1, the positioning seat, the light-emitting unit 3, and the supporting frame 4 form a unified whole, which is convenient for subsequent installation on the front side of the vehicle body and ensures the reliability of the installation structure.

[0031] Among them, the load-bearing frame 4 has a good structural load-bearing function, can reliably support the light-emitting unit 3 and the transparent skin 1, effectively disperse the load formed by the light-emitting unit 3 and the transparent skin 1 to the vehicle body, improve the overall stability of the structure, avoid the sagging problem of the vehicle front-end module, and meet the use requirements under vehicle collision or bumpy road conditions.

[0032] The positioning seat can be connected to the transparent skin 1 by welding or bonding. Through the positioning function of the positioning seat, the maximum offset of the light-emitting unit 3 can be optimized to ±1mm, ensuring the reliable installation of the light-emitting unit 3 and the accurate emission of light.

[0033] The locating seat and the supporting frame 4 are both made of PP (polypropylene). The locating seat is made of PP-TD20 material, which has 20% talc added to the polypropylene. PP-TD20 has the characteristics of low shrinkage, low warpage, and high modulus, ensuring the molding quality of the locating seat.

[0034] The load-bearing frame 4 is made of PP-GF30 material. PP-GF30 is polypropylene with 30% glass fiber added. It combines the advantages of polypropylene and glass fiber, and has high strength, high heat resistance, good processing performance and chemical stability. It makes the load-bearing frame 4 have better load-bearing capacity and improves its structural performance.

[0035] In some embodiments, the above-mentioned feature positioning seat and light emitting unit 3 can be used as follows Figure 4 、 Figures 6 and 7 The structure shown. Figure 4 、 Figures 6 and 7 The positioning seat is provided with a guide column 21 extending backward and a threaded sleeve 22, and the positioning platform is provided with a positioning hole 34 and a connecting hole 35 that pass through the front and back. The guide column 21 is plugged into the positioning seat in a one-to-one correspondence. The positioning seat and the positioning platform are connected by a threaded member 33 set through the connecting hole 35, and the threaded member 33 is threadedly engaged with the threaded sleeve 22.

[0036] In this embodiment, the guide column 21 provided on the positioning seat can be positioned and matched with the positioning hole 34 on the positioning platform, so that the upper and lower positions and the left and right positions of the positioning seat and the positioning platform are effectively limited. On this basis, the positioning seat and the positioning platform are reliably connected by the threaded cooperation of the threaded member 33 and the threaded sleeve, so that the relative position of the transparent skin 1 and the light-emitting unit 3 is limited, ensuring a reliable connection between the light-emitting unit 3 and the transparent skin 1, and avoiding the problem of structural looseness during driving.

[0037] Furthermore, axially extending reinforcement strips may be provided on the outer peripheries of the guide column 21 and the threaded sleeve 22 to improve the structural strength of the components and ensure good positioning and connection effects.

[0038] In some possible implementations, the feature positioning seat is used as follows Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 and Figure 7 The structure shown. Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 and Figure 7 The positioning seat includes an upper positioning seat 24 and a side positioning seat 25. The positioning platform includes an upper positioning platform 38 arranged in a one-to-one correspondence with the upper positioning seat 24 and a side positioning platform 39 arranged in a one-to-one correspondence with the side positioning seat 25. The upper positioning seat 24 is connected to the upper part of the transparent skin 1, and the side positioning seat 25 is connected to the side of the transparent skin 1.

[0039] In this embodiment, the positioning seat is used in combination with an upper positioning seat 24 and a side positioning seat 25. The upper positioning seat 24 can structurally position the upper area of ​​the light-emitting unit 3, and the side positioning seat 25 can position the side of the light-emitting unit 3, so that the light-emitting unit 3 can be accurately installed on the rear side of the light-transmitting skin 1.

[0040] Specifically, two upper positioning seats 24 and two side positioning seats 25 are provided. The two upper positioning seats 24 are symmetrically located on both sides of the central axis of the vehicle body, and the two side positioning seats 25 are symmetrically located on both sides of the central axis of the vehicle body and located outside the two upper positioning seats 24. The upper positioning seats 24 and the side positioning seats 25 are used in conjunction with each other to form a uniform distribution around the periphery of the light-emitting unit 3, ensuring that each position of the light-emitting unit 3 can be accurately positioned.

[0041] In some possible implementations, the above-mentioned characteristic light-transmitting skin 1 and the positioning seat are used as follows Figure 1 、 Figure 2 、 Figures 6 and 7 See also Figure 1 、 Figure 2 、 Figures 6 and 7A positioning plugboard 11 extending backward is provided on the transparent skin 1, and a plug-in hole 26 passing through from front to back is provided on the positioning seat. The plug-in hole 26 corresponds to the positioning plugboard 11 in a one-to-one plug-in fit.

[0042] In this embodiment, the positioning plate 11 provided on the light-transmitting skin 1 can be plugged into the insertion hole 26 on the positioning seat, achieving structural positioning of the light-transmitting skin 1 and the positioning seat in the left-right and up-down directions, ensuring the precise installation position of the positioning seat. The positioning plate 11 can be configured as a plate-like structure extending in the front-to-back direction, ensuring that it can be inserted backward into the insertion hole 26 of the positioning seat. The plate surface of the positioning plate 11 can be arranged in a horizontal direction, a vertical direction, or other directions, and can achieve structural positioning, effectively limiting the relative position of the light-transmitting skin 1 and the light-emitting unit 3, and achieving precise positioning between the two.

[0043] Specifically, a reinforcement platform 27 can be installed at the location where the insertion hole 26 is located on the positioning seat to compensate for the structural attenuation caused by the insertion hole 26 in this area. The reinforcement platforms 27 can be located on either side of the insertion hole 26, protruding toward the rear of the vehicle body. Furthermore, the positioning seat plate surface can also be configured as a boss structure 23 protruding toward the front of the vehicle body, with the insertion hole 26 extending through the boss structure 23, further enhancing the structural strength of this location.

[0044] Furthermore, two plug holes 26 can be set at intervals on the same positioning seat, and two positioning plug plates 11 are also provided on the transparent skin 1 corresponding to the same positioning seat to ensure reliable plugging and further improve the positioning accuracy.

[0045] In some possible implementations, the above-mentioned characteristic load-bearing frame 4 is adopted as follows Figure 5 The structure shown. Figure 5 The supporting frame 4 is provided with a plurality of weight-reducing holes 41 that pass through the supporting frame 4 , and the supporting frame 4 is connected to the light-emitting unit 3 via a plurality of connectors located on the periphery of the weight-reducing holes 41 .

[0046] In this embodiment, the load-bearing frame 4 is capable of effectively supporting the light-emitting unit 3 and the light-transmitting skin 1, and exhibits excellent structural strength and rigidity. While maintaining the required load-bearing capacity for these components, weight-reducing holes 41 can be provided on the load-bearing frame 4 to reduce the structural weight. This reduces material consumption, achieving both weight and cost reductions, and can reduce the overall weight of the front-end module by 30%-40%.

[0047] On this basis, since the rear side of the light-emitting unit 3 is provided with a driver chip 37 and a wiring harness port 36 protruding backward, avoidance holes 47 corresponding to the driver chip 37 and the wiring harness port 36 can be set through the supporting frame 4 to achieve structural avoidance and ensure effective installation of the structure.

[0048] In some embodiments, the above-mentioned characteristic light emitting unit 3 and the supporting frame 4 can be adopted as follows Figures 4 and 5 The structure shown. Figures 4 and 5 A connecting boss 31 protruding outward is provided on the rear side wall of the light-emitting unit 3, and a connecting recess 43 recessed backward to accommodate the connecting boss 31 is provided on the front side wall of the supporting frame 4. The connecting piece is arranged through the inner bottom wall of the connecting recess 43 and is connected to the connecting boss 31.

[0049] In this embodiment, when connecting the light-emitting unit 3 and the supporting frame 4, in order to improve the connection strength, a connecting boss 31 is provided on the rear side wall of the supporting frame 4, and a connecting groove is provided on the supporting frame 4. The connecting recess 43 corresponds to the connecting boss 31 in front and back. Thereafter, the connection with the connecting boss 31 is realized by passing through the inner bottom wall of the connecting recess 43 through a connecting member, thereby ensuring an effective connection between the supporting frame 4 and the light-emitting unit 3 and ensuring the reliability of the connection.

[0050] Specifically, the connecting member is a threaded connecting member such as a bolt or screw, and the connecting boss 31 is provided with a thread groove that can cooperate with the thread of the connecting member to ensure that the light-emitting unit 3 and the supporting frame 4 are effectively connected and fixed. At the same time, the above connection method is not only convenient for production and assembly, but also convenient for subsequent maintenance and replacement.

[0051] A plurality of connecting bosses 31 and connecting recesses 43 can be provided, and they can be arranged in one-to-one correspondence with each other, so that the light emitting unit 3 and the supporting frame 4 form a multi-point connection, thereby improving the reliability of the connection.

[0052] In some possible implementations, the above-mentioned characteristic light emitting unit 3 and the supporting frame 4 are as follows: Figures 4 and 5 The structure shown. Figures 4 and 5 The light emitting unit 3 is provided with an outer boss 32 extending backward, and the supporting frame 4 is provided with a lap platform 44 bent backward to support the lower part of the outer boss 32. There are a plurality of outer bosses 32 and lap platforms 44 corresponding to each other.

[0053] In this embodiment, the light-emitting unit 3 and the supporting frame 4 are connected by connectors, and a supporting and load-bearing structure that allows for overlapping is also provided between them. The overlapping platform 44 on the front side of the supporting frame 4 is supported below the outer boss 32 of the light-emitting unit 3, so that the weight of the light-emitting unit 3 is evenly distributed across multiple overlapping areas. This ensures that the supporting frame 4 stably supports the light-emitting unit 3, reduces the load on the connector, and can cope with vibration caused by road bumps during driving.

[0054] In order to avoid interference, part of the outer boss 32 provided on the upper edge of the light-emitting unit 3 can be integrally formed with the positioning platform, which not only meets the positioning requirements of the transparent skin 1 , but also meets the overlap requirements with the load-bearing frame 4 .

[0055] In some possible implementations, the above-mentioned characteristic load-bearing frame 4 is adopted as follows Figure 1 、 Figure 3 and Figure 5 The structure shown. Figure 1 、 Figure 3 and Figure 5 The upper edge of the transparent skin 1 is provided with a rear connecting portion 12 bent backward, and the top of the supporting frame 4 is provided with a front connecting seat 45 protruding forward and upward and located below the rear connecting portion 12. The rear connecting portion 12 is connected to the front connecting seat 45.

[0056] In this embodiment, the rear connecting portion 12 arranged on the upper edge of the translucent skin 1 can be reliably connected to the front connecting seat 45 on the top of the load-bearing frame 4, so that a connection is formed between the load-bearing component and the cover body. In addition, the connection between the light-emitting unit 3 and the load-bearing frame 4 makes the translucent skin 1, the positioning seat, the light-emitting unit 3 and the load-bearing frame 4 form a unified whole, which is convenient for subsequent reliable installation on the front side of the vehicle body, ensuring the integrity and connection stability of the entire installation structure, so as to meet different driving conditions of the vehicle.

[0057] On this basis, an upwardly extending positioning column 42 can be provided on the top of the supporting frame 4, and a positioning hole 34 is provided on the corresponding rear connecting part 12. Through the cooperation of the positioning column 42 and the positioning hole 34, the front and rear positions and left and right positions of the transparent skin 1 and the supporting frame 4 can be accurately positioned, thereby improving the convenience of connection.

[0058] In some possible implementations, the above-mentioned characteristic transparent skin 1 and the load-bearing frame 4 are as follows: Figure 1 、 Figure 3 and Figure 6 The structure shown. Figure 1 、 Figure 3 and Figure 6 The lower part of the transparent skin 1 is embedded with an active air intake grille 5 , and the lower edge of the supporting frame 4 has a lower connecting ear 46 extending downward, and the lower connecting ear 46 is connected to the active air intake grille 5 .

[0059] In this embodiment, the active air intake grille 5 is mounted beneath the translucent skin 1 and automatically adjusts the air intake volume based on the engine's real-time needs. Its operating mechanism collects information such as engine water temperature, oil temperature, air conditioning status, and intake air temperature, and then controls a motor to precisely adjust the grille's louver angles.

[0060] The lower connecting lug 46 at the lower edge of the supporting frame 4 is connected to the active air intake grille 5. This lug is attached to the frame of the active air intake grille 5, improving the reliability of the connection while preventing any interference with the operation of the grille. This ensures that the lower portion of the light-transmitting skin 1 is connected to the supporting frame 4, ensuring that the light-transmitting skin 1 is securely mounted on the front side of the supporting frame 4.

[0061] Based on the same inventive concept, embodiments of the present application further provide a vehicle including a light-emitting unit positioning and mounting structure. This vehicle allows for precise positioning and reliable installation of the light-emitting unit 3, effectively distributing the load using the load-bearing frame 4, improving the reliability of the structural connection and facilitating subsequent repair and replacement of the vehicle's front-end structure.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
