Description

Technical Field

[0001] This application relates to the technical field of vehicle exterior lighting devices for lighting purposes, and more specifically to automotive front fog light assemblies with cornering light functions. Background Technology

[0002] As a key lighting device in low-visibility environments such as fog and rain, the core function of automotive fog lights is to illuminate the road ahead with highly penetrating light while avoiding glare to drivers of oncoming vehicles, thus ensuring driving safety.

[0003] Traditional front fog lights are designed primarily to illuminate the area directly in front of the vehicle, resulting in a narrower lateral illumination range. When a vehicle turns, this can create blind spots in the side and front areas, especially in low visibility conditions. Drivers may struggle to anticipate obstacles or pedestrians on the side and front, increasing safety hazards during turns. To compensate for this deficiency, some models require separate cornering lights. However, these separate cornering lights not only increase manufacturing costs but also require additional installation space within the vehicle body.

[0004] A few front fog lights that integrate cornering lights typically use a combination of main light source and side supplementary light source or a complex reflector structure to achieve side supplementary lighting. This not only increases the design and manufacturing difficulty of the lamp body, but also easily causes light efficiency loss during light transmission. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a front fog light assembly for automobiles with cornering light function, comprising: A lamp housing, wherein the lamp housing has a receiving cavity and the front side of the lamp housing is light-transmitting; The support assembly is disposed within the receiving cavity; An LED light substrate is mounted on the bracket assembly, and an LED light source is provided on the LED light substrate; A thick-walled lens is disposed on the front side of the LED lamp substrate. The rear side of the thick-walled lens is the light-incident surface, which is a convex arc surface. The front side of the thick-walled lens is the light-exit surface, which is an ellipsoidal surface with its major axis horizontally arranged in the left-right direction.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the bracket assembly includes a fixed bracket and a decorative frame. The front side of the fixed bracket is provided with a plurality of horizontally spaced mounting surfaces and a connecting surface connecting two adjacent mounting surfaces. The mounting surfaces are perpendicular to a first direction, and the angle between the first direction and the vehicle axis is an acute angle. The decorative frame is provided with a first decorative surface opposite to each mounting surface and a second decorative surface connecting two adjacent first decorative surfaces. The LED lamp substrate and the thick-walled lens are disposed between the mounting surfaces and the first decorative surfaces and connected to the fixed bracket or the decorative frame. The first decorative surface is provided with a through hole, and the light-emitting surface of the thick-walled lens passes through the through hole.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: it further includes a dimming component, the two sides of the bracket component are rotatably mounted on the lamp housing through positioning columns, the dimming component is mounted on the lamp housing and connected to the bracket component, and the dimming component is used to adjust the pitch angle of the bracket component and the LED lamp substrate and thick-walled lens mounted on it.

[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the dimming component includes a dimming screw and a dimming nut, the dimming nut is installed on the bracket assembly, and the dimming screw is rotatably installed on the lamp housing and screwed into the dimming nut.

[0009] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: it also includes a circuit board, which is installed on the rear side of the bracket assembly and electrically connected to the LED lamp substrate.

[0010] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the lamp housing includes a base, a sealing member and a lampshade. The base is provided with the receiving cavity, the receiving cavity has an opening at the front side, the lampshade is installed at the opening at the front side of the base and surrounds the base to form the receiving cavity, and the sealing member is disposed between the base and the lampshade and seals them together.

[0011] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the lamp housing is further provided with a vent that communicates with the receiving cavity.

[0012] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a desiccant is also provided in the accommodating cavity.

[0013] The beneficial effects of this utility model are as follows: the light-incident surface is a convex arc surface, which can initially converge the divergent light emitted by the LED. At the same time, the thick-walled structure can limit the angle of upward refraction of light, pressing most of the light towards the near-ground area in front of the vehicle, avoiding the decrease in penetration caused by high-altitude scattering of light, and meeting the "close-range, low-angle" illumination standard of fog lights. Furthermore, by designing the light-emitting surface of the thick-walled lens as an ellipsoid with its major axis horizontally aligned left and right, the optical refraction properties of the ellipsoid allow the light emitted by the LED light source to form a wide lateral light distribution coverage. This effectively broadens the lateral illumination range, creating continuous and uniform illumination coverage in front of and to the sides of the vehicle. This effectively eliminates blind spots in the side-front view when turning, eliminating the need for separate corner lights or multi-light source components, thus achieving lateral supplementary lighting during turns. This design integrates fog light and corner light functions into one unit, simplifying the internal structure of the lamp body and the vehicle's electrical layout, reducing manufacturing costs and assembly difficulty, while also saving vehicle body installation space.

[0019] Reference Figures 1 to 6 This application proposes an embodiment of an automotive front fog light assembly with cornering light function, comprising: The lamp housing 10 has a receiving cavity and a light-transmitting part on the front side; The support assembly 20 is disposed within the receiving cavity; LED lamp substrate 30 is mounted on the bracket assembly 20, and LED light source 31 is provided on the LED lamp substrate 30; A thick-walled lens 40 is disposed on the front side of the LED lamp substrate 30. The rear side of the thick-walled lens 40 is the light-incident surface 41, which is a convex arc surface. The front side of the thick-walled lens 40 is the light-exit surface 42, which is an ellipsoidal surface with its major axis horizontally arranged in the left-right direction.

[0020] The light-incident surface 41 is a convex arc surface. The light-incident surface 41 can initially converge the divergent light emitted by the LED. At the same time, the thick-walled structure can limit the angle of upward refraction of light and press most of the light towards the near-ground area in front of the vehicle, avoiding the decrease in penetration caused by high-altitude scattering of light, which meets the "close distance, low angle" illumination standard of fog lights. Furthermore, by designing the light-emitting surface 42 of the thick-walled lens 40 as an ellipsoid with its major axis horizontally aligned to the left and right, the optical refraction properties of the ellipsoid allow the light emitted by the LED light source to form a wide lateral light distribution coverage. This effectively broadens the lateral illumination range, creating continuous and uniform illumination coverage in front of and to the sides of the vehicle. This effectively eliminates blind spots in the side-front view during turns, eliminating the need for separate corner lights or multi-light source components, thus achieving lateral supplementary lighting during turns. This design integrates fog light and corner light functions into one unit, simplifying the internal structure of the lamp body and the vehicle's electrical layout, reducing manufacturing costs and assembly difficulty, while also saving vehicle body installation space.

[0021] In this embodiment, the bracket assembly 20 includes a fixed bracket 21 and a decorative frame 22. The fixed bracket 21 has several horizontally spaced mounting surfaces 211 and a connecting surface 212 connecting two adjacent mounting surfaces 211 on its front side. The mounting surfaces 211 are perpendicular to a first direction, and the angle between the first direction and the vehicle axis is an acute angle. The decorative frame 22 has a first decorative surface 221 opposite to each mounting surface 211 and a second decorative surface 222 connecting two adjacent first decorative surfaces 221. The LED lamp substrate 30 and the thick-walled lens 40 are disposed between the mounting surfaces 211 and the first decorative surfaces 221 and connected to the fixed bracket 21 or the decorative frame 22. The first decorative surface 221 has a through hole 223, and the light-emitting surface 42 of the thick-walled lens 40 passes through the through hole 223.

[0022] In the bracket assembly 20, the mounting surface 211 of the fixed bracket 21 is perpendicular to the first direction. This angle design ensures that the mounting posture of the LED lamp substrate 30 and the thick-walled lens 40 forms an optimal light distribution angle with the vehicle's driving direction, ensuring that the light does not directly hit the oncoming vehicle while covering the blind spot in front of the side. The through hole 223 on the first decorative surface 221 provides a clearance channel for the light-emitting surface 42 of the thick-walled lens 40, ensuring that the light is emitted without obstruction. The first decorative surface 221 of the decorative frame 22 is arranged opposite to the mounting surface 211 to form an installation space, allowing the LED lamp substrate 30 and the thick-walled lens 40 to be accommodated between them. At the same time, the second decorative surface 222 connects to the adjacent first decorative surface 221 to form a closed decorative structure, ensuring an aesthetically pleasing appearance. In this embodiment, the LED lamp substrate 30 and the thick-walled lens 40 are fixedly mounted on the fixed bracket by fasteners.

[0023] The angle matching design of the mounting surface 211 with the first direction standardizes the installation posture of the optical components and ensures consistent light distribution during mass production; the decorative frame 22 not only conceals the internal mounting structure but also enhances the aesthetics of the lamp body. When installing the automotive front fog light assembly, the LED lamp substrate and thick-walled lens 40 can be pre-fixed to the fixing bracket 21 and decorative frame 22 before being installed into the lamp housing 10, simplifying the assembly process and improving production efficiency.

[0024] Preferably, a dimming component 50 is also included. Positioning posts 23 are provided on both sides of the bracket assembly 20. In this embodiment, the receiving cavity is provided with positioning holes that match the positioning posts 23. The positioning posts 23 are inserted into the positioning holes to connect the bracket assembly 20 with the lamp housing 10. The dimming component 50 is mounted on the lamp housing 10 and connected to the bracket assembly 20. The dimming component 50 is used to adjust the pitch angle of the bracket assembly 20 and the LED lamp substrate 30 and the thick-walled lens 40 mounted on it.

[0025] The LED light substrate 30, the thick-walled lens 40, the fixed bracket 21, and the decorative frame 22 form an integral structure. When the dimming component 50 adjusts the pitch angle of the light emitted by the front fog light assembly, it can adjust the pitch angle within the bracket assembly.

[0026] The positioning posts 23 on both sides of the bracket assembly 20 are inserted into the positioning holes of the lamp housing 10 to form a rotatable hinge structure, providing a rotation reference for pitch angle adjustment; the dimming assembly 50 is installed on the lamp housing 10 and connected to the bracket assembly 20. By driving the bracket assembly 20 to rotate around the axis of the positioning post 23, the LED lamp substrate 30 and the thick-walled lens 40 on it are driven to deflect synchronously, thereby changing the pitch angle of the light and adapting to the lighting needs of different vehicle models and different road conditions.

[0027] Specifically, the dimming assembly 50 includes a dimming screw 51 and a dimming nut 52. The dimming nut 52 is mounted on the bracket assembly 20. The dimming screw 51 is rotatably mounted on the lamp housing 10 and screwed into the dimming nut 52. When it is necessary to adjust the pitch angle, the dimming screw 51 is rotated to cause the nut to move on the dimming screw 51, which drives the dimming nut 52 to move the bracket assembly 20 along the screw axis, thereby causing the bracket assembly 20 to rotate around the positioning post 23, thus realizing the fine adjustment of the pitch angle.

[0028] In this embodiment, a circuit board 60 is also provided inside the lamp housing 10. The circuit board 60 is installed on the rear side of the bracket assembly 20 and electrically connected to the LED lamp substrate 30. Utilizing the rear space of the receiving cavity, the circuit board 60 and the LED lamp substrate 30 are positioned by the bracket assembly 20. It can be directly assembled on the bracket assembly 20 and then simultaneously installed into the lamp housing 10 along with the LED lamp substrate 30 and the thick-walled lens 40, which facilitates assembly.

[0029] In this embodiment, the lamp housing 10 includes a base 11, a sealing member 12, and a light-transmitting lampshade 13. The base 11 has a receiving cavity with an opening at its front. The lampshade 13 is installed at the front opening of the base 11 and surrounds the base 11 to form the receiving cavity. The sealing member 12 is disposed between the base 11 and the lampshade 13 and seals them together. The base 11 of the lamp housing 10 provides installation space for the bracket assembly 20, the LED lamp substrate, and the thick-walled lens 40 through the receiving cavity. Its front opening mates with the lampshade 13 to form a closed receiving cavity. The sealing member 12 is disposed between the base 11 and the lampshade 13 and fills the gap between them through compression deformation, preventing external moisture, dust, sand, and other impurities from entering the receiving cavity.

[0030] Preferably, the lamp housing 10 is also provided with a vent 14.

[0031] The vent 14 on the lamp housing 10 connects the cavity to the outside atmosphere, achieving air pressure balance between the cavity and the outside, and preventing abnormal air pressure caused by temperature changes from damaging the sealing structure. Specifically, the lamp housing 10 is provided with a vent cap that communicates with the inside of the cavity, and the vent cap is provided with a vent 14. A waterproof and breathable membrane can be used at the vent 14 to prevent external liquid water from entering the cavity.

[0032] Furthermore, a desiccant 70 is also provided inside the cavity. The desiccant 70 inside the cavity adsorbs water vapor, reduces the humidity inside the cavity, prevents water vapor from condensing on the surface of optical components or electronic components, and protects the light transmittance of optical components and the insulation of electronic components.

[0033] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
