Description

Technical Field

[0001] This invention relates to the field of automotive manufacturing technology, and in particular to a headlight assembly mounting structure. Additionally, this invention also relates to a vehicle. Background Technology

[0002] The front combination lamp assembly is located at the front of the vehicle body, and its main function is to provide front lighting for the entire vehicle system. The mounting structure of the front combination lamp assembly is a key design structure for the overall matching of the front of the vehicle, and it has many design requirements, such as stable connection strength, compliance with safety performance standards, and guarantee of gap surface differences; therefore, it is a key research topic in the field of vehicle body structure matching research and development.

[0003] The front combination light assembly is usually located in the gap area between the fender and the front bumper. The installation area formed by this gap also covers the functional area requirements of pedestrian protection reduction, so there is a technical challenge in the design of the strong and weak combination of the installation structure area.

[0004] In existing technologies, front combination lights are mostly installed using mounting brackets on the frame of the front nacelle. However, the design and structure of these mounting brackets have many shortcomings, lacking consideration for the installation and fixation of surrounding components such as fenders and front bumpers. This results in numerous problems, including difficulty in assembling the front combination lights with the surrounding fenders and front bumpers when installed separately, unstable connection strength after installation, gaps between connected components exceeding the error requirements, and inadequate pedestrian protection at the front of the fenders. Summary of the Invention

[0005] In view of this, the present invention aims to propose a headlight assembly mounting structure to improve the problem that the gap difference between the headlight assembly and the fender is prone to exceed the error requirement range.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] A headlight assembly mounting structure includes a mounting opening between a fender and a front bumper, a mounting bracket on the front nacelle frame corresponding to the mounting opening, and a headlight assembly.

[0008] The headlight assembly includes a lamp holder and a lamp body. The lamp holder is fastened to the mounting bracket by a plurality of mounting feet, and the lamp body forms a seal against the mounting opening.

[0009] The fender has a horn region located between the front hood and the lamp body, and the mounting bracket includes a fender support frame supported below the horn region, with at least one mounting foot fastened to the fender support frame on the side of the lamp holder near the horn region.

[0010] Furthermore, the mounting leg includes a first mounting leg disposed on the top of the lamp holder, and the mounting bracket also includes a headlight mounting bracket one disposed on the side beam assembly of the engine compartment corresponding to the first mounting leg; the first mounting leg is fastened to the headlight mounting bracket one.

[0011] Furthermore, the fender support frame includes a fender support plate connected between the nacelle side beam assembly and the nacelle longitudinal beam assembly, and a support frame disposed on the fender support plate; the ram's horn region is disposed on the top of the support frame.

[0012] Furthermore, the fender support plate has a top side beam connecting section, a downward sloping section, and a front section connected in sequence; the end of the top side beam connecting section is fixed to the engine compartment side beam assembly behind the lamp holder; the top side beam connecting section extends towards the interior of the vehicle in the left-right direction; the downward sloping section extends downward from the top side beam connecting section towards the front of the vehicle; the front section extends forward from the bottom of the downward sloping section; and the front end of the engine compartment longitudinal beam assembly is provided with a front support frame for supporting the front section; the mounting bracket also includes a fender mounting bracket one provided on the top side beam connecting section and a headlight mounting bracket two provided on the downward sloping section; the mounting feet include a second mounting foot and a third mounting foot spaced apart on the side of the lamp holder near the horn area;

[0013] The fender is fastened to the first fender mounting bracket at the rear edge of the horn area; the second mounting leg is fastened to the second headlight mounting bracket; the third mounting leg is fastened to the front end; and the support frame is located on the front section.

[0014] Furthermore, the support frame includes an "L"-shaped fender connecting bracket two, and a fender mounting bracket two disposed on the fender connecting bracket two; the fender connecting bracket two has a fixed section stacked on the front section, and a supporting section extending upward from the rear end of the fixed section; the fender mounting bracket two is "U"-shaped, including a front support section and a rear support section whose bottom ends respectively overlap the ends of the fixed section and the supporting section, and a horn-shaped receiving section connecting the top ends of the front support section and the rear support section; the horn area is disposed on the horn-shaped receiving section, and the front end of the horn area is connected to the top of the front support section.

[0015] Furthermore, the bottom end of the front support section is bent to form a lower flange that overlaps the end of the fixed section, and the end of the front section is provided with a positioning hole; corresponding to the positioning hole, a clearance groove is provided on both the lower flange and the fixed section, and a positioning post is provided on the third mounting leg; the positioning post is inserted into the positioning hole through the clearance groove.

[0016] Furthermore, the mounting leg includes a fourth mounting leg located at the bottom of the lamp holder, and the mounting bracket also includes a front mounting bracket fixed to the front end of the engine compartment longitudinal beam assembly corresponding to the fourth mounting leg, with the fourth mounting leg fastened to the front mounting bracket.

[0017] Furthermore, the fender also has a side front end located below the outside of the lamp body and connected to the front bumper. The mounting feet include a fifth mounting foot located on the side of the lamp holder near the side front end. The mounting bracket also includes a fender mounting bracket three fixed to the outside of the cabin side beam assembly corresponding to the fifth mounting foot. The side front end and the fifth mounting foot are both fastened to the fender mounting bracket three.

[0018] Furthermore, among the plurality of mounting feet, at least one of the mounting feet is provided with a guide positioning structure between it and the fastening part on the mounting bracket for guiding the headlight assembly into place.

[0019] And / or, the fender mounting bracket three is adjustablely positioned on the engine compartment side beam assembly in the left-right direction of the vehicle.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] The headlight assembly mounting structure of the present invention provides a mounting bracket on the front nacelle frame located within the mounting opening, and a fender support bracket corresponding to the yoke area of ​​the fender. This provides a fixed support for the yoke area and a unified mounting base for the yoke area and the mounting feet inside the lamp holder. This allows for more precise control of the relative position between the lamp holder of the headlight assembly and the adjacent fender, resulting in better splicing effect and accuracy. This ensures the quality of gaps and surface differences at the splicing points, and helps to improve the problem that the gap and surface difference between the headlight assembly and the fender easily exceed the error requirement range.

[0022] Furthermore, by installing a fender support plate below the spur area, a good foundation for the arrangement of the support frame can be provided. Fender mounting bracket one, headlight mounting bracket two, and fender mounting bracket two are sequentially installed on the fender support plate, providing a very reasonable and uniform installation and fixing foundation for the spur area and the inner side of the headlight assembly. This facilitates the tight installation of the spur area and related mounting feet, and reliably ensures the accuracy of the mating surface difference between the headlight body and the spur area.

[0023] Meanwhile, by installing a second fender connecting bracket between the second fender support plate and the second fender mounting bracket, the two brackets together form a frame-like support structure. This not only supports the saddle-end section on the second fender mounting bracket to the required height for the saddle-end area, but the entire support frame also provides sufficient buffer space and crumple zone energy absorption. When the front of the vehicle suffers an offset collision, the headlight assembly and the saddle-end area of ​​the fender can crumple inwards to absorb energy. Especially when this area collides with a pedestrian, it can reduce the impact injury to the pedestrian, thus protecting them from severe injury. By incorporating multiple weakening structures on the front support section of the second fender mounting bracket, the buffering performance and crumple zone effect of the second fender mounting bracket can be further improved.

[0024] Furthermore, by setting a fifth mounting foot on the outer side of the headlight assembly (the side facing the outside of the vehicle), and correspondingly setting a fender mounting bracket three on the outer side of the engine compartment side beam assembly, a unified mounting base is provided for the installation and fixation of the headlight assembly and the front side of the fender, ensuring that the gap difference between the two is controlled within the required range. By setting a fender fixing bracket and a fender connecting bracket one between the fender mounting bracket three and the engine compartment side beam assembly, and utilizing the elongated hole on the fender connecting bracket one, the position of the fender connecting bracket one can be finely adjusted in the left and right directions of the vehicle. This overcomes the problem of excessive errors that may occur during the processing and assembly of various components, ensuring the accuracy of the mounting position of the headlight assembly and the front side of the fender.

[0025] Another object of the present invention is to provide a vehicle employing the headlight assembly mounting structure described herein. The vehicle of the present invention possesses the technical advantages of the aforementioned headlight assembly mounting structure. Attached Figure Description

[0062] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0063] Example 1

[0064] This embodiment relates to a headlight assembly mounting structure, which can improve the problem that the gap surface difference between the headlight assembly 2 and the fender 11 easily exceeds the error requirement range; an exemplary structure is as follows: Figures 1 to 5 As shown.

[0065] Overall, the headlight assembly mounting structure includes a mounting opening 10 located between the fender 11 and the front bumper 12, a mounting bracket on the front nacelle frame corresponding to the mounting opening 10, and a headlight assembly 2. The headlight assembly 2 includes a lamp holder 20 and a lamp body 27. The lamp holder 20 is secured to the mounting bracket by multiple mounting feet, and the lamp body 27 blocks the mounting opening 10. Meanwhile, the fender 11 has a yoke region 110 located between the hood 13 and the lamp body 27. The mounting bracket includes a fender support frame supported below the yoke region 110, and at least one mounting foot secured to the fender support frame is provided on the side of the lamp holder 20 near the yoke region 110.

[0066] It should be emphasized that the aforementioned "horn region 110" refers to the narrow, elongated portion of the fender 11 located between the hood 13 and the lamp body 27, i.e., the portion indicated by the dashed frame in the accompanying drawings (reference number 110). This portion extends forward of the vehicle and has a relatively small width, making it prone to deformation and displacement. By providing a fender support bracket for support and fixation, the accuracy and reliability of its assembly position can be improved. It should be noted that, based on the above overall design concept, the technical solution of this invention can adopt various different specific implementation structures, forms, or configuration sequences. For example, the aforementioned mounting bracket can be an integral unit or an assembly of multiple separate brackets; the specific arrangement sequence and device method between the fastening parts on the mounting bracket and the mounting feet of the lamp holder can also be flexibly adjusted. For parts required for the overall implementation but not covered in the above overall setup, reasonable and flexible designs can be made by referring to mature design methods in the field and the actual situation during implementation. The specific implementation schemes described below are only one of the many solutions that can be formed by the various combinations and variations mentioned above. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the various combinations and variations of the above-mentioned specific forms that can form numerous solutions, as well as the specific implementation scheme of this embodiment, are all within the protection scope of this invention.

[0067] Based on the above design concepts, such as Figures 1 to 5 As shown, the headlight assembly mounting structure of this embodiment mainly includes three parts: an assembly structure for fixing the upper part of the headlight assembly 2 (including the top of the lamp holder 20 and the inner side of the side near the horn region 110 of the fender 11), an assembly structure for fixing the lower part of the headlight assembly 2 (i.e., the bottom of the lamp holder 20), and an assembly structure for fixing the side part of the headlight assembly 2 (i.e., the outer side of the lamp holder 20 near the front end 111 of the side of the fender 11). The three assembly structures will be described in turn below.

[0068] In this embodiment, as Figure 6 , Figure 7 and combined Figure 20 , Figure 21 As shown, a first mounting leg 21 is provided on the top of the lamp holder 20, and the aforementioned mounting bracket includes a headlight mounting bracket 37 corresponding to the first mounting leg 21, which is mounted on the engine compartment side beam assembly 15. Based on the configuration of the headlight mounting bracket 37, a first screw hole 372 can be opened on the headlight mounting bracket 37, and the first mounting leg 21 is fastened to the headlight mounting bracket 37 through the first screw hole 372. The headlight mounting bracket 37 for mounting the headlight assembly 2 is provided on the engine compartment side beam assembly 15, and the form of fastening bolt 6 and screw hole can securely fix the top of the headlight assembly 2 to the vehicle body; it has the advantages of simple processing structure and convenient operation and assembly.

[0069] The specific structural form of the cabin side beam assembly 15 can be designed with reference to the existing side beam structure. In this embodiment, the cabin side beam assembly 15 includes an inner side beam plate 150 and an outer side beam plate 151 that are fastened together. The bottom of the aforementioned headlight mounting bracket 37 is stacked at the top edge of the inner side beam plate 150 and the outer side beam plate 151.

[0070] Furthermore, in this embodiment, a guide positioning structure for guiding the headlight assembly 2 into place can be selectively provided between each mounting leg of the lamp holder 20 and the corresponding fastening part on the mounting bracket; of course, a guide positioning structure can be provided between all mounting legs and their corresponding fastening parts, or a guide positioning structure can be provided only between individual mounting legs and their corresponding fastening parts.

[0071] In this embodiment, the guide positioning structure provided between the first mounting leg 21 and the headlight mounting bracket 37 is specifically configured as follows: the first mounting leg 21 is provided with a first guide groove 210 arranged along the front-rear direction of the vehicle, and the headlight mounting bracket 37 is provided with a first guide post 370 and a fitting flange 371; the first guide post 370 slides in the first guide groove 210, thereby guiding the headlight assembly 2 to be inserted along the front-rear direction; and when the headlight assembly 2 is inserted into place, the fitting flange 371 abuts against the lamp holder 20 to form a limit.

[0072] A guide structure consisting of a guide groove and a guide post is provided between the first mounting leg 21 and the headlight mounting bracket 37 to facilitate faster and more accurate insertion and positioning of the headlight assembly 2. The fitting flange 371 on the headlight mounting bracket 37 provides a good limiting effect for the inserted headlight assembly 2. The first guide post 370, the fitting flange 371, and the first screw hole 372, in conjunction with the fastening bolt 6 on the first mounting leg 21 and the first guide groove 210, can accurately position the headlight assembly 2 in the front-rear, left-right, and up-down directions of the vehicle, ensuring the accuracy of the installation position of the top of the headlight assembly 2. Of course, it should be noted that the positions of the guide groove and guide post involved in the above-mentioned guide structure can be interchanged. That is, the first guide post 370 can be set on the first mounting leg 21, and the first guide groove 210 can be set on the headlight mounting bracket 37 accordingly. Such a guide fit is also feasible.

[0073] Based on the above configuration, the orientation of the first guide post 370 and the first screw hole 372 on the headlight mounting bracket 37 can be flexibly configured. For example, their axes can be arranged along the vertical direction of the vehicle, or along the horizontal direction of the vehicle as shown in the attached figures of this embodiment. Preferably, the axes of the first guide post 370 and the first screw hole 372 in this embodiment are both arranged along the horizontal direction of the vehicle. The horizontal arrangement of this embodiment facilitates the screwing and installation of the bolt 6 from the side.

[0074] The specific configuration of the fender support frame can, of course, be flexibly adjusted. In this embodiment, for example... Figure 5 and combined Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the fender support frame includes a fender support plate 31 connected between the nacelle side beam assembly 15 and the nacelle longitudinal beam assembly 14, and a support frame mounted on the fender support plate 31; the aforementioned horn region 110 is located at the top of the support frame. The frame structure effectively meets the support height requirements of the horn region 110.

[0075] There are, of course, various designs for the specific structural form of the fender support plate 31. In this embodiment, the fender support plate 31 has a top side beam connecting section 310, a downward sloping section 311, and a front section 312 connected in sequence. The end of the top side beam connecting section 310 is fixed to the engine compartment side beam assembly 15 behind the lamp holder 20. The top side beam connecting section 310 extends towards the interior of the vehicle in the left-right direction. The downward sloping section 311 extends downward from the top side beam connecting section 310 towards the front of the vehicle. The front section 312 extends from the bottom of the downward sloping section 311 towards the front of the vehicle. The front end of the engine compartment longitudinal beam assembly 14 is provided with a front support frame 30 supported at the bottom of the front section 312. The front support frame 30 can be an integral structure. However, in this embodiment, the front support frame 30 includes a front support plate 300 fixed to the front end of the engine compartment longitudinal beam assembly 14 and a front upper extension plate 301 connected to the top of the front support plate 300 and extending upward. The front upper extension plate 301 is supported at the middle position of the front section 312.

[0076] By setting a fender support plate 31 below the horn region 110, a good arrangement foundation can be provided for the fixed installation of the fender lamp holders 2011 and 20. Obviously, the fender support plate 31 can be fixedly connected to the frame inside the cabin, for example, between the cabin longitudinal beam assembly 14 and the cabin side beam assembly 15. The fender mounting bracket 1 32, the headlight mounting bracket 2 38, and the fender mounting bracket 2 34 are sequentially arranged on the fender support plate 31, providing a unified installation foundation for the horn region 110 and the inner side of the headlight assembly 2, ensuring reliable accuracy of the mating surface difference between the lamp body 27 and the horn region 110.

[0077] Based on the fender support bracket configuration, structures for fastening the fender 11 and lamp holder 20 are provided on the fender support plate 31 and support frame. Specifically, the mounting bracket in this embodiment also includes a fender mounting bracket 32 ​​on the top side beam connecting section 310 and a headlight mounting bracket 38 on the downward sloping section 311; the mounting legs of the lamp holder 20 include a second mounting leg 22 and a third mounting leg 23, which are spaced apart and located on the side of the lamp holder 20 near the horn region 110. The edge of the fender 11 located behind the horn region 110 is fastened to the fender mounting bracket 32; the second mounting leg 22 is fastened to the headlight mounting bracket 38, and the third mounting leg 23 is fastened to the end of the front section 312; the support frame is fixedly mounted on the front section 312.

[0078] The support frame is preferably constructed by welding multiple plates. In this embodiment, the support frame includes an "L"-shaped fender connecting bracket 33 and a fender mounting bracket 34 disposed on the fender connecting bracket 33. Specifically, as... Figure 10 , Figure 11 and Figure 12 As shown, in this embodiment, the front section 312 of the fender support plate 31 is provided with an "L"-shaped fender connecting bracket 33. The fender connecting bracket 33 has a fixed section 330 stacked on the front section 312, and a supporting section 331 extending upward from the rear end of the fixed section 330. The fender mounting bracket 34 in this embodiment is "U"-shaped and includes a rear support section 340 and a front support section 342 whose bottom ends overlap the ends of the fixed section 330 and the supporting section 331, respectively, and a ram's horn receiving section 341 connecting the top ends of the rear support section 340 and the front support section 342.

[0079] Meanwhile, the second mounting bracket 38 is provided with a second screw hole 380, and the second mounting leg 22 is provided with a through hole. By inserting the fastening bolt 6 through the through hole and screwing it into the second screw hole 380, the second mounting leg 22 can be fixed on the second mounting bracket 38.

[0080] Based on the above structural configuration, in this embodiment, fender mounting bracket 1 32 is mounted on the top side beam connecting section 310, headlight mounting bracket 2 38 is mounted on the downward tilting section 311, and fender mounting bracket 2 34 is mounted on the front section 312. Clearly, this structure and arrangement are compatible with the downward tilting posture of the fender horn region 110 towards the front of the vehicle and also suitable for the fixed position of the second mounting foot 22 located in the middle of the inner side of the headlight assembly 2, which is beneficial for improving the overall installation effect and ease of operation of the mounting structure.

[0081] Based on the above structural form, in this embodiment, the saddle bumper region 110 is mounted on the saddle bumper support section 341, and the front end of the saddle bumper region 110 is connected to the top of the front support section 342. By setting a fender connecting bracket 33 between the fender support plate 31 and the fender mounting bracket 34, the fender mounting bracket 34 and the fender connecting bracket 33 are combined to form a frame-like orifice structure. This not only supports the saddle bumper support section 341 on the fender mounting bracket 34 to the height required for the saddle bumper region 110, but the entire frame structure also has sufficient buffer space and crumple zone energy absorption function. When the front of the vehicle suffers an offset collision, the headlight assembly 2 and the saddle bumper region 110 of the fender 11 can crumple towards the interior of the vehicle to absorb energy. In particular, when this part collides with a pedestrian, it can reduce the impact injury to the pedestrian and achieve the purpose of protecting the pedestrian from serious injury.

[0082] In addition, multiple weakening structures 343 can be provided on the front support section 342. By providing multiple weakening structures 343 on the front support section 342 of the fender mounting bracket 2 34, the buffering performance and crumple effect of the fender mounting bracket 2 34 can be further improved. There are, of course, several options for the specific form of the weakening structures 343; for example, multiple large or small weakening rib structures or crumple rib structures can be provided on the front support section 342; or a section of the front support section 342 can be designed as a curved structure.

[0083] Based on the assembly configuration of the fender support plate 31, the fender connecting bracket 33, and the fender mounting bracket 34 described above, preferably, as follows: Figure 10 , Figure 11 and Figure 13 , Figure 20 , Figure 22 , Figure 23As shown, in this embodiment, the bottom end of the front support section 342 is bent to form a lower flange 344 that overlaps the end of the fixed section 330. The front end of the front section 312 is provided with a positioning hole 313 and a third screw hole 314. Moreover, corresponding to the positioning hole 313, a clearance groove 35 is provided on the lower flange 344 and the fixed section 330; corresponding to the third screw hole 314, a through hole 36 is provided on the lower flange 344 and the fixed section 330. The mounting leg in this embodiment also includes a third mounting leg 23 provided on the side of the lamp holder 20. The third mounting leg 23 is provided with a positioning post 230 that is positioned and engaged with the positioning hole 313. The third mounting leg 23 is screwed into the third screw hole 314 by a fastening bolt 6.

[0084] A lower flange 344 is provided at the bottom end of the front support section 342, and the lower flange 344 overlaps the front end of the fixed section 330. In this way, from top to bottom, the lower flange 344, the fixed section 330, and the front section 312 overlap to form a three-layer plate structure. Preferably, the front ends of the three plates are aligned. At this time, a solid mounting base is formed at the overlapping part for the installation and fixing of the third mounting leg 23. Through the positioning hole 313 and its clearance groove 35, as well as the third screw hole 314 and through hole 36, the third mounting leg 23 can be accurately and conveniently positioned and fixed to the front end of the fender support plate 31, thereby providing a reliable mounting point for the installation and fixing of the headlight assembly 2 at the front position inside the headlight assembly 2 (the side facing the vehicle interior).

[0085] The above mainly describes the assembly structure of the upper part of the headlight assembly 2; for the assembly structure of the lower part and the side of the headlight assembly 2, the following scheme can be adopted.

[0086] like Figure 14 , Figure 15 and combined Figure 24 , Figure 25 As shown, the mounting feet of the lamp holder 20 in this embodiment also include a fourth mounting foot 24 disposed at the bottom of the lamp holder 20, and the aforementioned mounting bracket also includes a front mounting bracket 42 fixed to the front end of the nacelle longitudinal beam assembly 14 corresponding to the fourth mounting foot 24; the front mounting bracket 42 can of course be directly welded to the nacelle longitudinal beam assembly 14, however, in this embodiment, as Figure 14 As shown, based on the configuration of the front support plate 300, a front connecting plate 40 is fixedly connected to the outside of the front support plate 300. A bent front connecting bracket 41 is provided on the top of the front connecting plate 40. The aforementioned front mounting bracket 42 is provided on the front connecting bracket 41. The configuration of multiple connecting brackets allows the front mounting bracket 42 to support the fixed installation of the fourth mounting leg 24 in a suitable posture.

[0087] Based on the above configuration, a fourth screw hole 420 can be provided on the front mounting bracket 42, and the fourth mounting leg 24 can be fastened to the front mounting bracket 42 through the fourth screw hole 420.

[0088] A fourth mounting bracket 24 is provided at the middle position of the bottom of the lamp holder 20, and a front mounting bracket 42 is provided at the front end of the engine compartment longitudinal beam assembly 14, providing a reliable mounting point for the bottom of the headlight assembly 2. At the same time, since the front bumper 12 is also indirectly fixed to the front end of the engine compartment side beam assembly 15, the front bumper 12 and the headlight assembly 2 have a common mounting base. This provides a reliable guarantee for the quality control of the connection gap between the lamp body 27 and the front bumper 12, and helps to improve the problem that the gap surface difference between the headlight assembly 2 and the front bumper 12 is prone to exceed the error requirement range.

[0089] like Figures 16 to 19 As shown, the mounting feet of the lamp holder 20 in this embodiment also include a fifth mounting foot 25 located on the side of the lamp holder 20 near the front end 111. The mounting bracket in this embodiment also includes a fender mounting bracket three 52 fixed to the outside of the cabin side beam assembly 15 corresponding to the fifth mounting foot 25. Accordingly, a fifth screw hole 520 and a fender mounting hole 522 can be provided on the fender mounting bracket three 52. The fifth mounting foot 25 is fastened to the fender mounting bracket three 52 through the fifth screw hole 520, and the front end 111 is fastened to the fender mounting bracket three 52 through the fender mounting hole 522.

[0090] Specifically, in this embodiment, the fender mounting bracket 3 52 is bent, with a fender mounting hole 522 on one side of the plate and a fifth screw hole 520 and a connecting hole 523 on the other side of the plate. The front end of the side front end 111 of the fender 11 has a front flange 112, which overlaps the plate where the fender mounting hole 522 is located. A fastening bolt 6 passing through the front flange 112 is screwed into the fender mounting hole 522, thereby fixing the side front end 111 to the fender mounting bracket 3 52. The connecting hole 523 is used to fix the fender mounting bracket 3 52 to the fender connecting bracket 1 51, and the fifth screw hole 520 is used to install the fifth mounting leg 25.

[0091] By setting a fifth mounting foot 25 on the outer side of the headlight assembly 2 (the side facing the outside of the vehicle), and correspondingly setting a fender mounting bracket 3 52 on the outer side of the engine compartment side beam assembly 15, a unified mounting base is provided for the installation and fixing of the headlight assembly 2 and the side front end 111, which can ensure that the gap surface difference between the two is controlled within the required range.

[0092] In addition, such as Figure 19 and Figure 25As shown, in this embodiment, a guide positioning structure for guiding the headlight assembly 2 into place is also provided between the fifth mounting leg 25 and the fender mounting bracket 3 52. This guide positioning structure is specifically configured as follows: the fender mounting bracket 3 52 has a second guide groove 521 arranged along the longitudinal direction of the vehicle, and the fifth mounting leg 25 has a second guide post 250; the second guide post 250 slides within the second guide groove 521 to guide the headlight assembly 2 into place along the longitudinal direction. The above design is similar to the guide structure provided between the first mounting leg 21 and the headlight mounting bracket 37. The cooperation between the guide groove and the guide post between the fender mounting bracket 3 52 and the fifth mounting leg 25 provides excellent convenience for guiding and positioning the headlight assembly 2 during the insertion process, facilitating the rapid installation and positioning of the headlight assembly 2 in a predetermined position and its fixing on the corresponding bracket.

[0093] In actual implementation, the fender mounting bracket 352 can certainly be directly fixed to the nacelle side beam assembly 15; however, in this embodiment, as Figure 18 As shown, in this embodiment, a fender fixing bracket 50 is fixedly mounted on the outer side of the cabin side beam assembly 15. A third fender mounting bracket 52 is connected to the fender fixing bracket 50 via a first fender connecting bracket 51. Furthermore, the first fender connecting bracket 51 has multiple elongated holes 510 arranged along the left-right direction of the vehicle. The first fender connecting bracket 51 is screwed to the fender fixing bracket 50 by multiple fastening bolts 6 passing through each elongated hole 510. Given that the cabin side beam assembly 15 includes an inner side beam plate 150 and an outer side beam plate 151 that are fastened together, it is preferable that the fender fixing bracket 50 can be welded to the outer side beam plate 151.

[0094] By setting a fender fixing bracket 50 and a fender connecting bracket 51 between the fender mounting bracket 3 52 and the engine compartment side beam assembly 15, and utilizing the elongated hole 510 provided on the fender connecting bracket 51, the position of the fender connecting bracket 51 can be finely adjusted in the left and right directions of the vehicle. This overcomes the problem of excessive errors that may occur during the processing and assembly of various parts, and ensures the accuracy of the installation position of the headlight assembly 2 and the side front end 111 of the fender 11.

[0095] In addition, such as Figure 1 Combination Figure 24 As shown, for the connection and fit between the bottom edge of the front bumper 12 and the lamp body 27, a snap-fit ​​structure 26 for snapping the front bumper 12 can be set on the lamp holder 20 near the bottom edge of the lamp body 27, so as to achieve snap-fit ​​fixation of the edge position of the front bumper 12 and improve the quality of gap and surface difference control at the splicing position of the lamp body 27 and the front bumper 12.

[0096] In summary, the headlight assembly mounting structure of this embodiment, by setting a mounting bracket on the front nacelle frame located within the mounting opening 10 and setting a fender support frame corresponding to the horn area 110 of the fender 11, provides a unified mounting and fixing foundation for the horn area 110 and the mounting feet inside the lamp holder 20 while providing fixed support for the horn area 110. Furthermore, the fastening assembly structure between the upper, lower, and side parts of the headlight assembly 2 and the mounting bracket not only achieves three-point fixing of the headlight assembly 2, but also makes the relative position control of the lamp holder 20 of the headlight assembly 2 and the adjacent fender 11 more precise, resulting in better splicing effect and accuracy. This ensures the quality of the gaps and surface differences at the splicing parts, which helps to improve the problem that the gaps and surface differences between the headlight assembly 2 and the fender 11 are prone to exceeding the error requirement range.

The headlight assembly 2 is precisely mounted on the front of the vehicle to achieve precise connection and cooperation between the headlight assembly 2, the fender 11, and the front bumper 12.

[0099] Of course, the headlight assembly 2 can be a front combination lamp of various shapes, and the surface shapes of the fender 11 and the front bumper 12 can also be adjusted and changed accordingly. With reference to the structural design concept of the present invention, the headlight assembly 2 can be accurately installed and fixed at the mounting opening 10 formed between the fender 11 and the front bumper 12.

[0100] The installation structure of this invention adopts a combination of guiding, positioning, and fully constrained installation method to realize the assembly of the headlight assembly 2. It has many structural advantages such as convenient operation, stable connection strength, and easy guarantee of gap surface difference. At the same time, it solves the problems that the front horn area 110 of the fender 11 is prone to injuring people when it collides with pedestrians, the safety protection performance is substandard, and the safety collision injury value is high.
