Background Technology

[0002] Adaptive Front-Lighting System (AFS) is a system that automatically adjusts the headlights based on the steering wheel angle, vehicle yaw rate, and speed. It adapts to the current steering angle, maintaining the light direction consistent with the vehicle's current direction of travel. In poorly lit or winding road conditions, it expands the driver's field of vision to ensure optimal illumination of the road ahead.

[0003] To achieve AFS (Adaptive Front-lighting) functionality and compensate for deviations in the cutoff line between light and dark areas caused by vehicle vibrations and component tolerances, a position adjustment system needs to be installed on the lighting module. Currently used adjustment systems are overly complex, employing a dual-system adjustment mechanism for both vertical and horizontal adjustments. This results in excessive costs, hindering widespread application and making maintenance extremely complicated. Furthermore, the overly complex adjustment system occupies too much space within the lamp, limiting the current mainstream narrow-aperture design of automotive lights. Utility Model Content

[0034] Light source assembly 7 Rotating arm shaft 05 Detailed Implementation

[0035] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0036] This utility model discloses a lighting module and vehicle light that can be adjusted horizontally and vertically. The vertical and horizontal rotation of the module is achieved through adjustable screws and bevel gears, thereby enabling adjustment of the horizontal and vertical position of a single module and improving the module's positional accuracy. Simultaneously, it achieves high-precision matching between modules. This not only facilitates more accurate fulfillment of specifications in terms of light pattern and optical performance but also compensates for errors caused by product size and assembly.

[0037] The lighting module that can be adjusted horizontally and vertically according to the present invention includes an optical lens assembly, a light source assembly 7, a bracket assembly 4, a support base 6, a linear drive mechanism, and a second bevel gear 5. The optical lens assembly is connected to the light source assembly 7 through the bracket assembly 4. The bracket assembly 4 includes a bracket body and a first bevel gear 401 and a ball socket 402 installed on the side of the bracket body. The gear surface of the first bevel gear 401 meshes with the second bevel gear 5, and the axis of the first bevel gear 401 coincides with the horizontal optical axis O1 of the module.

[0038] The second bevel gear 5 is fixed on the support base 6 and connected to an external rotary drive mechanism. The second bevel gear 5 is used to drive the lighting module to rotate around the horizontal optical axis 01 of the module. A rotating arm is provided on the side of the bracket body. The rotating arm is rotatably disposed in the support base 6. The drive end of the linear drive mechanism is connected to the ball socket 402 and is used to drive the lighting module to rotate around the rotating arm shaft 05. The rotating arm shaft 05 is perpendicular to the horizontal optical axis 01 of the module, and both the rotating arm shaft 05 and the horizontal optical axis 01 of the module are perpendicular to the light output direction of the optical lens assembly.

[0039] Two sets of rotary drive mechanisms enable the module to rotate around two vertical axes. Preferably, when the linear drive mechanism pushes out, the module rotates around the rotating arm shaft 05. At this time, the angle between the axes of the first bevel gear 401 and the second bevel gear 5 also rotates by the corresponding angle. Therefore, both the first bevel gear 401 and the second bevel gear 5 are set as spiral bevel gears to compensate for the angle and enable the first bevel gear 401 and the second bevel gear 5 to transmit smoothly.

[0040] The optical lens assembly includes a spring clip 2, an optical lens 1, and an optical lens housing 3. The optical lens housing 3 is a hollow structure with openings at both ends. The optical lens 1 is mounted on one end of the optical lens housing 3 via the spring clip 2 on the side, and the other end of the optical lens housing 3 is connected to the light source assembly 7 via a hollow bracket assembly 4.

[0041] The optical module also includes a bushing 10 and a slide groove. The bushing 10 is rotatably fitted onto the outside of the rotating arm and slidably disposed in the slide groove, which is vertically mounted on the top of the support base 6. The midpoint of the contact surface between the bushing 10 and the slide groove, and the meshing point between the first bevel gear 401 and the second bevel gear 5, are both located on the rotating arm shaft 05. The linear drive mechanism includes an adjusting screw 8, the end of which is hinged to a ball socket 402. The ball socket 402 and the first bevel gear 401 are respectively mounted on both sides of the bracket body. The slide groove and the bushing 10 are both located on the same side of the first bevel gear 401.

[0042] The light source assembly 7 includes a light source element and a light-blocking plate 701, the light-blocking plate 701 being installed between the light source element and the optical lens assembly. The second bevel gear shaft 03 is parallel to the linear drive shaft 04 of the linear drive device.

[0043] The working principle of this utility model is as follows:

[0044] like Figure 1-2 As shown, the spring clip 2 assembles the optical lens 1 and the optical lens housing 3 together. The bracket assembly 4 assembles the optical lens assembly and the light source assembly 7 together. The second bevel gear 5 is assembled with the support base 6 and together constitutes the horizontal drive device and the vertical support device. After the bushing 10 is assembled with the bracket assembly 4, it matches the slide groove of the support base, playing an auxiliary role and improving the stability of the module. After the adjusting screw 8 is assembled with the ball socket 402 of the bracket assembly 4, it together constitutes the vertical adjustment device and the horizontal support device.

[0045] During the module's horizontal adjustment process, the second bevel gear 5 rotates around the second bevel gear shaft 03. The rotation of the second bevel gear 5 drives the first bevel gear 401 to rotate the module horizontally to achieve a predetermined inner and outer horizontal angle. After the rotation stops, the first bevel gear 401 and the second bevel gear 5 mesh and lock together. During the adjustment process, the bushing 10 slides in the groove, providing support. After assembly, the bushing 10 structure matches the groove of the support base and forms a stable horizontal axis with the gear meshing point, namely the rotating arm shaft 05, which provides favorable support for stabilizing the module's horizontal state.

[0046] During the vertical adjustment process of the module, the adjusting screw 8 drives the ball socket 402 upwards or downwards along the linear drive shaft 04, causing the module to rotate along the rotating arm shaft 05 formed by the upper meshing point of the module and the bushing 10. The first bevel gear 401 and the second bevel gear 5 rotate along the vertical rotation arc 02 to adjust vertically up and down to achieve a predetermined horizontal angle. After adjustment, the first bevel gear 401 and the second bevel gear 5 engage and lock. During the adjustment process, the bushing 10 rotates at the end of the rotating arm, providing support. After assembly, the bushing 10 structure matches the slide groove of the support base and forms a stable horizontal axis with the gear meshing point, providing favorable support for stabilizing the vertical state of the module. The auxiliary bushing 10 assembly structure ensures the stability of the module during the adjustment movement. This ensures the positional accuracy of the module after adjustment, and even during vehicle operation, it can resist problems such as falling and displacement caused by vibration. Precise horizontal and vertical angle adjustment of the module achieves high matching between modules. This not only allows for more precise fulfillment of specifications in terms of light pattern and optical performance, but also compensates for errors caused by product size and assembly. The simplified assembly system saves on module development and design costs as well as module assembly costs.

[0047] Example 1

[0048] This embodiment provides an optical module capable of fine-tuning rotation around two vertical axes. The optical lens 1 includes an incident light structure, an exit light structure, and front and rear positioning and positioning structures for the incident light structure. The spring clip 2 is formed of a highly elastic metal structure and fixes the optical lens 1 and the optical lens housing 3. The optical lens housing 3 is formed of a high-strength plastic structure, supports the optical lens 1, and is reasonably matched with the bracket assembly 4, and is fixed by four self-tapping screws 9.

[0049] The support assembly 4 is formed of a high-strength plastic structure, including the support body, a first bevel gear 401, and a ball socket 402. The second bevel gear 5 is formed of a plastic structure with good toughness and wear resistance. It rotates around the shaft three via a rotating gear, perfectly meshing with the first bevel gear 401. The support base 6 is formed of a high-strength plastic structure, supporting the second bevel gear 5 and the bushing structure 10. The support base is separable from the module, allowing for precise angle adjustment of the first bevel gear 401 and the bushing assembly structure 10.

[0050] The light source assembly 7 includes a light source component and a light-blocking plate 701. The light source assembly is assembled with the bracket assembly 4 using self-tapping screws, providing the module with a light source that meets optical performance requirements. The adjusting screw 8 is formed of a high-strength metal structure and is assembled with the ball joint 402 of the bracket assembly. By driving the adjusting screw, rotating it around the vertical rotation axis O4, the module is moved back and forth along the light emission direction, achieving precise vertical adjustment of the module.

[0051] The self-tapping screws 9 are formed of a high-strength metal structure, fixing the optical lens housing 3 and the bracket assembly 4, and playing a fixing role in the assembly of the front and rear ends of the module. The bushing 10 is formed of a plastic structure with good toughness and wear resistance, and cooperates with the support base 6 to provide reliable support during the horizontal and vertical adjustment of the module. This ensures that the light-blocking plate 701 is stably formed with a complete and clear cutoff line shape.

[0052] This invention utilizes a perfect meshing of bevel gears and beveled arc gears to achieve large-angle adjustment of the module in both horizontal and vertical directions. Simultaneously, the assembled bushing structure, after matching the sliding groove of the support base, forms a stable horizontal axis with the gear meshing point. Together with the bevel gear meshing self-locking structure, this provides strong support for stabilizing the module's vertical and horizontal state. This ensures the module's stability during adjustment, thus guaranteeing strong positional accuracy after adjustment and resisting problems such as falling and shifting caused by vibration even during vehicle operation. Precise horizontal and vertical angle adjustment of the module achieves a high degree of matching between modules. This not only facilitates more accurate fulfillment of specifications for light patterns and optical performance but also compensates for errors caused by product size and assembly. The simplified assembly system saves on module development and design costs as well as the cost of the module assembly. It not only improves the stability of the product structure but also reduces system complexity.

[0053] This invention, on the one hand, satisfies the requirement for large-angle headlight adjustment and compensates for the deviation of the light cutoff line caused by vehicle vibration and the cumulative tolerance of components, thus ensuring that the driver has a sufficient field of vision directly ahead. On the other hand, it also meets the requirements of AFS (Adaptive Front-lighting System) for headlights, ensuring a sufficiently large field of vision for the driver's side.

[0054] In a preferred embodiment, the light source is a surface-mount LED, which is integrated on the PCBA or on a heat sink and connected to the PCB board via metal wires. In other embodiments, other types of light sources can be selected according to actual needs.

[0055] This invention can be configured to generate multiple light distributions, each of which is of a different type. The type of each light distribution is any one of the following: low beam lighting, high beam lighting, adaptive low beam lighting, ADB high beam lighting, corner fog light lighting, urban road mode lighting, rural road mode lighting, highway mode lighting, curve mode lighting, rain and fog mode lighting, position signal light, turn signal light, daytime running light, welcome light, ambient light, etc.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0057] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the substantive content of this utility model.
