Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting technology, and more specifically, it relates to a connection structure for automotive lighting parts. Background Technology

[0002] Automotive lighting fixtures have undergone continuous technological innovation, resulting in increasingly diverse shapes and complex internal structures. This increased styling necessitates the disassembly of numerous internal parts. These components require interconnecting fastening structures to meet installation requirements. Common fastening methods include screws, clips, welding, and riveting. Screw fastening offers the best stability. Screw fastening solutions can be categorized based on the number of parts being fastened: individual fastening and overlapping screw fastening. When two parts are individually fastened, the design involves using screws to attach one component to the other. This solution is suitable for products with few parts. However, if there are many parts, using individual fastening for all parts will result in a large number of screws. While stability remains unaffected, screw costs increase, installation time is prolonged, and labor costs rise. This method is not recommended for products with many components. Therefore, for connecting multiple parts, overlapping fastening can be used. This method uses a single screw to fasten multiple parts, reducing the number of screws required. However, this solution currently has significant limitations, mainly due to three issues. First, this stacking method can only support a maximum of two parts. If three or more parts are stacked, the effective engagement depth of the screws will be insufficient, requiring longer screws and resulting in insufficient tightening force, affecting installation stability. Second, product deformation and assembly errors are unavoidable. Currently, the stacked cross-section structure cannot correct deformation, nor does it have other positioning structures. When the first and second parts are placed, the three layers of parts stacked together cannot guarantee the coaxiality of the three screw holes. If the holes are misaligned, the screws will not be able to be tightened. Third, this stacking method is prone to mis-assembly issues, as there is no error-proofing. Because there is no difference in appearance and no error-proofing in the structure, employees may tighten the screws in the first or second process before all connecting parts are installed. Mis-assembly requires rework, and failing to detect mis-assembly poses a significant risk.

[0003] Existing technology includes a bolt for securing a vehicle headlight, with publication number CN211039333U. This technology discloses a bolt for securing a vehicle headlight, comprising a headlight positioning bolt segment, a fixing bolt segment, and an intermediate flange located between the headlight positioning bolt segment and the fixing bolt segment. The intermediate flange has a fastening structure on the side closest to the headlight positioning bolt segment for engaging with a tightening sleeve. The outer edge of the fastening structure is located outside the headlight positioning bolt segment. This headlight fastening bolt has a reasonable structural design; the tool sleeve is fitted onto the fastening structure outside the intermediate flange, preventing contact between the tool sleeve and the vehicle body during tightening. Tightening is simple and facilitates easy tightening of the intermediate flange to fit snugly against the vehicle body, ensuring stable and reliable fixation. However, this technology does not address the technical problem and solution of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is: to provide a simple structure for connecting automotive headlight parts that effectively solves the problem of insufficient screw fit size when multiple parts are stacked and connected, and can reliably achieve the fastening of three or more layers of stacked parts, ensure the concentricity of multi-layer stacked parts, and guarantee the reliability of multi-layer part connections.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model is a connecting structure for automotive headlight parts, including a main body, screws and multiple connecting parts. The main body is provided with screw posts with internal threaded holes inside. The connecting parts are provided with connecting through holes, and support ribs are provided at the positions of the through holes on the lower surface of the connecting parts.

[0007] The supporting rib is a ring-shaped supporting rib, which is arranged along the outer ring of the through hole.

[0008] The main body part has a positioning recess on its upper surface.

[0009] The screw post is welded to the upper surface of the main body part.

[0010] The screw post includes a screw post body and a screw post end. The screw post body passes under the main body part, and the screw post end rests against the lower surface of the main body part.

[0011] The lower end face of the supporting rib is provided with a positioning protrusion.

[0012] The connecting parts include a first layer of connecting parts, a second layer of connecting parts, and a third layer of connecting parts.

[0013] When the main body, the first connecting part, the second connecting part and the third connecting part are connected, the through holes of the first connecting part, the second connecting part and the third connecting part pass through the screw post.

[0014] The diameter of the screw tip is larger than the diameter of the through hole.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] The automotive headlight component connection structure of this utility model features screw posts protruding from the mounting surface of the main body component. For multiple connecting parts, through holes are provided. During connection, the connecting parts are fitted onto the outer ring of the screw posts. Multiple connecting parts are stacked, with the bottommost connecting part fitting against the main body component and the topmost connecting part fixed by screws. This achieves positioning of the connecting parts relative to the main body component, preventing movement of the connecting parts. The diameters of the through holes and screw posts are controlled to ensure concentricity. Support ribs are provided at the through hole positions on the lower surface of each connecting part, providing reliable support and abutment against the connecting parts below them. After multiple connecting parts are connected, screws are tightened into the internal threaded holes of the screw posts, with the screw ends abutting against the upper surface of the topmost connecting part, reliably fixing the multiple connecting parts. When multiple connecting parts are connected to the main body component, other screws can also be used to connect corresponding connecting parts to other components, effectively achieving multi-point connection and fixation of the connecting parts and ensuring connection reliability. In this way, even when multiple connecting parts are stacked together, it is not necessary to continuously increase the length of the screws; instead, the length of the screw post can be controlled, and short screws are sufficient. At the same time, by setting the length of the screw post according to the number and thickness of the connecting parts, if the corresponding number of connecting parts are not fully installed, even if the screws are tightened, multiple connecting parts cannot be reliably fixed. Only when the corresponding number of connecting parts are fully installed, and the screw tip applies force to the uppermost connecting part after tightening, can multiple connecting parts be reliably fixed, effectively eliminating the problem of misinstallation caused by missing connecting parts.

[0026] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0027] As attached Figure 1 - Appendix Figure 7As shown, this utility model is a connection structure for automotive headlight parts, including a main body part 1, screws 2, and multiple connecting parts. The main body part 1 has screw posts 3 with internal threaded holes 4. The connecting parts have connecting through holes 5, and support ribs 6 are provided at the positions of the through holes 5 on the lower surface of the connecting parts. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In this structure, screw posts 3 are arranged on the main body part 1, protruding from the mounting surface of the main body part 1. For the multiple connecting parts, through holes 5 are provided respectively. During connection, the connecting parts are fitted onto the outer ring of the screw posts 3. Multiple connecting parts are stacked, with the bottom connecting part fitting against the main body part 1, and the top connecting part fixed by screws 2. This achieves positioning of the connecting parts relative to the main body part 1, preventing the connecting parts from shifting relative to the main body part 1. Controlling the diameter of the through holes and screw posts ensures concentricity control. Support ribs 6 are provided at the positions of the through holes 5 on the lower surface of each connecting part, providing reliable support and abutment between the connecting part with the support ribs 6 and the connecting parts below it. After multiple connecting parts are connected, screws 2 are tightened into the internal threaded holes 4 of the screw post 3. The screw tip of screw 2 abuts against the upper surface of the uppermost connecting part, reliably fixing the multiple connecting parts. When multiple connecting parts are connected to the main body part 1, other screws can also be used to connect the corresponding connecting parts to other components, effectively achieving multi-point connection and fixing of the connecting parts and ensuring connection reliability. In this way, even if multiple connecting parts are stacked, it is not necessary to continuously increase the length of the screws; instead, the length of the screw post 3 can be controlled, and short screws 2 are sufficient. At the same time, by setting the length of the screw post according to the number and thickness of the connecting parts to be arranged, if the corresponding number of connecting parts are not all installed in place, even if the screws are tightened, multiple connecting parts cannot be reliably fixed. Only when the corresponding number of connecting parts are all installed in place, the screw tip applies force to the uppermost connecting part after tightening, thereby reliably fixing multiple connecting parts. This effectively eliminates the problem of misinstallation caused by missing connecting parts. The automotive headlight component connection structure described in this utility model has a simple structure and effectively solves the problem of insufficient screw fit dimensions when multiple components are stacked together. It can reliably achieve the fastening of three or more layers of stacked components, ensure the concentricity of multi-layered components, and guarantee the reliability of multi-layered component connections.

[0028] The supporting rib 6 is a ring-shaped supporting rib, which is arranged along the outer ring of the through hole 5. Due to the cedar wood structure, the supporting rib prevents the connecting parts from passing through the screw post, and the ring-shaped supporting rib 6 reliably abuts against the connecting part located below, achieving reliable positioning of the upper and lower parts.

[0029] The main body part 1 has a positioning recess on its upper surface. Each connecting part has a positioning recess on its upper surface. The lower end face of the support rib 6 has a positioning protrusion. With the above structure, after multiple connecting parts are connected in place and the screws are tightened, the positioning protrusion of each support rib is engaged in the positioning recess below, thereby achieving the positioning of the vertically arranged parts and preventing relative rotation of the parts.

[0030] The screw post 3 is welded to the upper surface of the main body part 1. As an embodiment 1, the above structure allows for a reliable connection between the screw post and the main body part through welding.

[0031] The screw post 3 includes a screw post body and a screw post end. The screw post body passes under the main body part 1, and the screw post end rests against the lower surface of the main body part 1. In embodiment 2, the screw post body passes through the main body part and extends above the main body part 1. Then, a connecting part is fitted onto the screw post 3 to ensure reliable connection.

[0032] The connecting parts include a first-layer connecting part 7, a second-layer connecting part 8, and a third-layer connecting part 9. When the main body part 1, the first-layer connecting part 7, the second-layer connecting part 8, and the third-layer connecting part 9 are connected, the through holes 5 of the first-layer connecting part 7, the second-layer connecting part 8, and the third-layer connecting part 9 respectively pass through the screw post 3. The diameter of the screw tip 10 of the screw 2 is larger than the diameter of the through hole 5. With the above structure, after multiple connecting parts are stacked and tightened, reliable fixation to the main body part is achieved. Alternatively, the screw post may not pass through the uppermost connecting part; instead, the screw 2 passes through the uppermost connecting part, and then the screw is screwed onto the connecting screw post, with the screw tip 10 of the screw 2 connecting to the upper fiber.

[0033] The automotive headlight component connection structure of this utility model features a screw post 3 protruding from the mounting surface of the main body part 1. For multiple connecting parts, through holes 5 are provided. During connection, the connecting parts are fitted onto the outer ring of the screw post 3. Multiple connecting parts are stacked, with the lowest connecting part fitting against the main body part 1 and the highest connecting part fixed by screws 2. This achieves positioning of the connecting parts relative to the positioning posts of the main body part 1, preventing the connecting parts from shifting. The diameters of the through holes and screw posts are controlled to ensure concentricity. Support ribs 6 are provided at the positions of the through holes 5 on the lower surface of each connecting part, providing reliable support and abutment between the connecting part with the support ribs 6 and the connecting part below it. After multiple connecting parts are connected, screws 2 are screwed into the internal threaded holes 4 of the screw post 3. The screw ends of the screws 2 abut against the upper surface of the highest connecting part, reliably fixing the multiple connecting parts. When multiple connecting parts are connected to the main body part 1, other screws can be used to connect the corresponding connecting parts to other components, effectively achieving multi-point connection and fixation of the connecting parts and ensuring connection reliability. Thus, even when multiple connecting parts are stacked, it is not necessary to continuously increase the length of the screws; instead, the length of the screw post 3 can be controlled, and short screws 2 are sufficient. Simultaneously, by setting the length of the screw post according to the required number and thickness of the connecting parts, if the corresponding number of connecting parts are not all installed, even with screw tightening, multiple connecting parts cannot be reliably fixed. Only when the corresponding number of connecting parts are all installed, the screw tip applies force to the uppermost connecting part after tightening, thus reliably fixing multiple connecting parts. This effectively eliminates the problem of mis-installation caused by insufficient connecting parts.

Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
