Description

Technical Field

[0001] This invention belongs to the field of automotive headlight technology, and specifically relates to a headlight mounting and positioning structure. Background Technology

[0002] Dimensional engineering is a concept that covers the entire process of product design, tooling design, component manufacturing, and assembly. Through process quality control, it aims to reduce costs, accelerate pilot production, shorten the R&D cycle, and ultimately improve the overall quality of vehicle development. From early-stage pre-research to later-stage production matching, dimensional engineering is integral and its importance cannot be overstated.

[0003] As a crucial part of the overall vehicle exterior matching process, the installation quality of the headlights directly impacts the achievement of the Design-to-Survey (DTS) goals for the front fascia, thus affecting the overall aesthetics and engineering precision of the vehicle. It is both a key area of ​​focus for users and a critical and challenging aspect of the vehicle matching process. Automakers typically try to meet DTS requirements by developing fixtures, improving the precision of the components involved in the matching process, or setting up workstations for online adjustments and assembly. However, these methods are often ineffective, either increasing overall vehicle costs or impacting production efficiency, without fundamentally resolving the matching relationship between the fender and surrounding components.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] A headlight mounting and positioning structure, such as Figure 1 As shown, it includes fender 1, upper crossbeam 2, headlight 3, and lower bracket 4. Figure 1 (Not shown). The headlight 3 integrates multiple brackets, which are connected to the fender 1, upper crossbeam 2, and lower bracket 4 to achieve the positioning of the headlight 3 in the X / Y / Z directions of the vehicle body. Moreover, the upper crossbeam 2 is located at the upper end of the headlight 3, and the fender 1 and lower bracket 4 are located at both ends of the headlight 3 and connected to the upper crossbeam 2.

[0066] Furthermore, such as Figure 2 As shown, the headlight 3 uses three positioning points and is installed through four mounting points. Specifically, the headlight 3 is connected to the upper crossbeam 2 through the first and second mounting points, connected to the fender 1 through the first, third, and third positioning points, and connected to the lower bracket 4 through the second positioning point and the fourth mounting point.

[0067] It should be noted that, in Figure 2 In the middle, a fender front upper bracket 203 is welded to the outer side of the right end of the upper crossbeam 2. This fender front upper bracket 203 overlaps with the side of the fender 1 and is then connected by bolts. Therefore, the fender front upper bracket 203 and the upper crossbeam 2 of the headlight 3 need to be supplied as a whole. At the same time, the structural design ensures that the Z-direction height of the bracket is adjustable. The purpose is to ensure that the Z-direction dimensional deviation of the first positioning point and the second positioning point is controlled within ±0.5mm, so as to ensure that the appearance DTS of the headlight 3 and the surrounding parts is achieved.

[0068] Furthermore, the first positioning point includes a first positioning hole 101 and a first positioning pin 301. Wherein, for example... Figure 2 As shown, the first positioning hole 101 is formed on the surface of the fender 1; as Figure 3 As shown, the first positioning pin 301 is integrated into one end of the headlight 3. Moreover, the first positioning pin 301 passes through the first positioning hole 101 and the front upper bracket 203 of the fender that overlaps with the fender 1, and is used to position the headlight 3 along the X-axis and Y-axis of the vehicle body.

[0069] It should be noted that the size of the first positioning hole 101 is φ8.2mm, the size of the first positioning pin 301 on the headlight 3 is φ8.0mm, and the single-sided gap between the first positioning pin 301 and the first positioning hole 101 is 0.1mm.

[0070] It needs to be further explained that, such as Figure 5 The image shown is a partial view of the first positioning point, where a slot is formed at the end of the first positioning pin 301. Additionally... Figure 6 for Figure 5 A cross-sectional view of the AA side, wherein the end of the first locating pin 301 is chamfered so as to mate with the first locating hole 101.

[0071] Furthermore, the second positioning point includes a third positioning pin 304 and a third positioning hole 401. Specifically, in combination... Figure 2 and Figure 3 It can be seen that the third positioning hole 401 is formed on the surface of the lower bracket 4. The third positioning pin 304 is integrated into the headlight 3. The third positioning pin 304 cooperates with the third positioning hole 401 to position the headlight 3 along the Z-axis of the vehicle body.

[0072] It should be noted that in some embodiments, the third positioning hole 401 is a 9×11.0mm elongated hole along the X direction of vehicle travel, and the third positioning pin 304 is a φ8mm cross positioning pin. The adjustment amount of 0.5mm on each side is used to absorb the welding deviation of the vehicle body.

[0073] It needs to be further explained that, such as Figure 7 The image shown is a partial view of the second positioning point. Figure 8 for Figure 7 A cross-sectional view of the BB plane, through Figure 8 It can be seen that the third positioning pin 304 is an integral structure with the bracket on the headlight 3, and it passes through the lower bracket 4 to fix the headlight 3 in the Z-axis direction.

[0074] Furthermore, the third positioning point includes the second positioning hole 102 and the second positioning pin 303. For example... Figure 2 and Figure 3 As shown, the second positioning hole 102 is formed on the surface of the fender 1, and the second positioning pin 303 is integrated into the headlight 3; the second positioning pin 303 cooperates with the second positioning hole 102 to position the headlight 3 in the Z direction on the vehicle body.

[0075] It should be noted that in some embodiments, the second positioning hole 102 is a 9×14.5mm semi-circular notch opened along the X direction of the vehicle body, the second positioning pin 303 is a φ8mm positioning pin, and the lower part of the second positioning pin 303 fits with the hole, while the upper part leaves an adjustment amount of 1.0mm to absorb the deviation of the fender piece and assembly, thereby realizing the Z-direction positioning of the headlight 3 on the vehicle body.

[0076] It needs to be further explained that, Figure 9 This is a partial view of the third positioning point, and the structure of its CC section is as follows: Figure 10 As shown, a circular groove is formed at the end of the second locating pin 303.

[0077] Furthermore, the first mounting point includes a first nut 201 and a third mounting hole 306. For example... Figure 2 and Figure 4 As shown, the first nut 201 is projected onto the surface of the upper crossbeam 2; the third mounting hole 306 is opened on the headlight 3; the first nut 201 and the third mounting hole 306 are connected by bolts to control the position of the headlight 3 in the Z direction of the vehicle body.

[0078] It should be noted that in some embodiments, the first nut 201 is an M6 nut, and the third mounting hole 306 is a φ11mm mounting through hole. The two are fixed by M6 bolts to achieve the Z-axis positioning of the headlight 3 on the vehicle body.

[0079] Furthermore, the second mounting point includes a second nut 202 and a fourth mounting hole 307. For example... Figure 2 and Figure 4 As shown, the second nut 202 is projected onto the surface of the upper crossbeam 2; the fourth mounting hole 307 is opened on the headlight 3; and the second nut 202 and the fourth mounting hole 307 are connected by bolts to control the position of the headlight 3 in the Z direction of the vehicle body.

[0080] It should be noted that the second nut 202 is an M6 nut, and the fourth mounting hole 307 is a φ11mm mounting through hole. The two are fixed with M6 bolts to achieve the Z-axis positioning of the headlight 3 on the vehicle body.

[0081] Furthermore, the third mounting point includes the first mounting hole 103 and the third nut 302. For example... Figure 2 and Figure 3 As shown, the first mounting hole 103 is formed on the surface of the fender 1; the third nut 302 is welded to the headlight 3; the first mounting hole 103 and the third nut 302 are connected by bolts to fix the headlight 3 in the Y direction of the vehicle body.

[0082] It should be noted that in some embodiments, the first mounting hole 103 on the fender 1 is a φ11mm circular mounting through hole, and the third nut 302 installed on the headlight 3 is an M6 spring nut. The two are fixed by M6 bolts to achieve the Y-axis positioning of the headlight 3 on the vehicle body.

[0083] Furthermore, the fourth mounting point includes a second mounting hole 305 and a fourth nut 402. Specifically, the second mounting hole 305 is formed on the headlight 3; the fourth nut 402 is projected onto the surface of the lower bracket 4; the second mounting hole 305 and the fourth nut 402 are connected by bolts to fix the headlight 3 in the X-direction of the vehicle body.

[0084] It should be noted that in some embodiments, the fourth nut 402 welded on the lower bracket 4 is an M6 nut, and the second mounting hole 305 opened on the headlight 3 is a φ11mm circular mounting through hole. The two are fixed by the M6 ​​nut to achieve the X-axis positioning of the headlight 3 on the vehicle body.

[0085] Furthermore, the three positioning points and mounting points mentioned above are all set around the position of the headlight 3. The first positioning point is located at the end of the headlight 3 near the fender 1 and on the upper front bracket 203 of the fender; the second positioning point is located at the end of the headlight 3 away from the fender 1 and on the lower bracket 4; the third positioning point is located below the first positioning point and at the front end of the fender 1; the first mounting point is located at the upper left of the headlight 3; the second mounting point is located at the upper right of the headlight 3; the third mounting point is located at the right end of the headlight 3 and at the front end of the fender 1; and the fourth mounting point is located at the left end of the headlight 3 and on the lower bracket 4.
