Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a novel automotive headlight housing. Background Technology
[0002] As the core lighting device for nighttime vehicle operation, the installation stability, sealing protection, and structural strength of automotive headlights directly affect lighting performance and safety. The headlight housing, as a key component supporting the light source assembly and connecting the vehicle body to the lamp cover, must withstand various conditions during long-term use, including driving vibrations, temperature changes, external impacts, and corrosion from rain, snow, and dust. Currently, traditional automotive headlight housings generally suffer from the following problems: First, unreasonable positioning structure design, often employing single or two-point positioning methods, leading to significant positioning deviations during installation and offsetting the light source's illumination angle, affecting lighting accuracy; Second, insufficient structural strength, with scattered and monotonous reinforcing rib layouts, making them prone to problems such as mounting plate breakage and housing deformation under long-term vibration, reducing service life; Third, poor sealing performance, often using a single-layer sealing structure, making it easy for rainwater and dust to seep into the lamp body, leading to short circuits and damage to the light source assembly. Utility Model Content
[0003] To address some of the problems existing in the prior art, this utility model provides a novel automotive headlight housing. This automotive headlight housing is suitable for the installation of headlights in automotive lighting systems, enabling precise positioning, stable assembly, and reliable protection of automotive headlights.
[0004] To achieve the above objectives, this utility model provides a novel automotive headlight housing, comprising a housing body, wherein the housing body is an integrally formed arc-shaped hollow cavity structure for accommodating the installation of the internal light source components of the headlight; the open end of the arc-shaped hollow cavity structure corresponds to the convex end of the housing body for adapting to the installation of the automotive headlight; the closed end of the arc-shaped hollow cavity structure corresponds to the concave end of the housing body for positioning and installation of the housing body with the vehicle body mounting base; a first positioning mounting plate and a second positioning mounting plate are provided on one side of the concave end of the housing body, and a third positioning mounting plate is provided on the other side corresponding to the second positioning mounting plate; the edge of the housing body extends outward and forms an annular sealing flange, and protrusions are provided at intervals on the sealing flange; headlight lens holders are provided on the protrusions for the detachable installation of the headlight lens; multiple first positioning mounting holes and second positioning mounting holes are also provided on the positioning connection end face, and a wiring groove is provided on the side end of the housing body.
[0005] During assembly and use, the bottom shell body is first positioned using the first, second, and third positioning mounting plates on its concave end. It is then fixed to the vehicle body mounting base using the positioning mounting holes on each mounting plate. Multiple first and second positioning locking holes on the concave end face of the bottom shell body assist in limiting its position. Furthermore, the annular reinforcing ribs outside the positioning mounting holes and the spaced reinforcing connecting ribs on the side ends of the mounting plates enhance the structural strength and stability of the mounting area. Simultaneously, the cross-shaped positioning protrusions within the range of the intersecting reinforcing ribs on the side ends of the bottom shell body further contribute to its stability. The positioning protrusions enable precise positioning and assembly. Next, the internal light source components of the headlight are placed on one side of the convex end face of the base body. The headlight wires are neatly stored using the wiring groove and pass through the circular wiring port in the wiring groove to complete the wiring connection inside the base body. Finally, the headlight cover is detachably snapped onto the protrusions and headlight cover clips spaced apart on the annular sealing flange of the base body edge. When the headlight cover is in contact with the sealing flange, the rubber seal in the annular sealing groove is compressed, achieving a stable installation and waterproof and dustproof seal for the headlight cover.
[0006] The beneficial effects of this utility model are as follows: The bottom shell body adopts an integrally molded hollow cavity structure, combined with the differentiated design of concave and convex end faces, to achieve precise adaptation with the vehicle body and headlight components; the first, second, and third positioning mounting plates are distributed in a distributed layout, combined with the annular reinforcing ribs on the outside of the positioning mounting holes and the reinforcing connecting ribs on the side ends, which not only improves the accuracy of positioning and installation, but also enhances the connection strength between the mounting plates and the bottom shell body, preventing breakage due to vibration; the cross reinforcing ribs on the side ends of the bottom shell body form a grid structure, combined with the cross positioning protrusions and the auxiliary positioning protrusions with positioning blocks, which not only significantly improves the overall bending resistance and impact resistance of the bottom shell. The performance also ensures precise installation of the base shell, indirectly guaranteeing the synchronous and accurate installation of the internal light source components of the headlight, thus improving the lighting effect. The annular sealing groove and embedded rubber seal on the inner side of the sealing flange form an effective seal after fitting and engaging with the headlight cover, preventing moisture and dust from entering the lamp body and improving the protection level. The design of the wiring groove and the circular wiring outlet allows for the orderly storage and safe installation of wires, avoiding damage to the wiring caused by long-term friction, while simplifying the internal assembly process. The headlight cover snap-fit structure on the protrusion facilitates the detachable installation and maintenance of the cover, balancing installation stability and ease of operation. In summary, this base shell structure is compact and rationally laid out, significantly improving positioning accuracy, structural strength, sealing protection, assembly convenience, and service life, and has broad application prospects and practical value.

The cross reinforcing rib group includes transverse reinforcing ribs and longitudinal reinforcing ribs. The transverse reinforcing ribs and longitudinal reinforcing ribs are vertically intersected to form a grid structure. Multiple cross positioning protrusions and auxiliary positioning protrusions are also provided within the range of the cross reinforcing rib group.
[0009] As a further improvement of this utility model, in order to improve the accuracy and reliability of positioning; the height of the cross positioning protrusion is 10mm to 15mm, and its cross-section is cross-shaped; the height of the auxiliary positioning protrusion is 8mm to 12mm, and its middle part is a cylindrical structure; the diameter of the cylindrical structure is 8mm to 10mm, and multiple positioning blocks are evenly spaced on its outer side wall.
[0010] As a further improvement of this utility model, in order to achieve orderly storage, safe installation and neat layout of the wires, ensure the smoothness of the internal electrical connection of the headlight, and at the same time provide a certain protection for the wires to prevent them from being worn during the use of the headlight; the cross-section of the wiring groove is U-shaped and the groove depth is 15mm to 18mm; a wiring conduction port is provided in the wiring groove, which is circular and communicates with the inside of the bottom shell body for orderly storage and installation of the wires.
[0011] As a further improvement of this utility model, in order to effectively prevent moisture, dust, etc. from entering the headlight, extend the service life of the headlight, and improve the working reliability of the headlight in various environments, an annular sealing groove is provided on the inner side of the sealing flange. The width of the sealing groove is 2-3mm and the depth is 3-5mm. A rubber sealing element is embedded in the sealing groove.
