[0036] Detailed Implementation
[0037] 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.
[0038] This utility model provides an adjustment mechanism for a vehicle headlight module, referring to... Figures 1-9 As shown, the adjustment mechanism mainly consists of a headlight module 1, a first adjustment bracket 4, and a second adjustment bracket 5. The headlight module 1 is rotatably connected to the first adjustment bracket 4 in the vertical direction, allowing for pitch adjustment on the first adjustment bracket 4. The first adjustment bracket 4 is rotatably connected to the second adjustment bracket 5 in the horizontal direction, and it moves vertically up and down on the second adjustment bracket 5. Through the first and second adjustment brackets 4 and 5, the headlight module 1 can not only rotate horizontally but also move vertically, compensating for the light-blocking problem caused by rotation adjustment within the headlight. This allows for smaller headlight mirrors that can be hidden inside the vehicle body, enabling more flexible design.
[0039] The headlight module 1 includes a module bracket 2 and a module heat sink 3. Two second ball joints 15 are mounted on the module bracket 2 and installed on two side walls along the X direction of the headlight module 1. Two first ball joints 8 are mounted on the module heat sink 3 and located on the same side along the Y direction of the headlight module 1. The first ball joints 8 and the second ball joints 15 are pre-installed on the headlight module 1 to form a module assembly 12.
[0040] A pair of ball-end contouring grooves 21 are provided on the first adjusting bracket 4. A pair of second ball-end seats 15 on the module assembly 12 are respectively installed in the two ball-end contouring grooves 21, and then covered by two ball-end brackets 9. Each side of the ball-end bracket 9 is locked with two screws 11. A screw base 7 is installed on one end of the first adjusting bracket 4 along the Y direction. A vertical adjusting screw 6 is provided on the screw base 7. The vertical adjusting screw 6 is rotated and adjusted along the Y direction. One end of the vertical adjusting screw 6 is embedded in a first ball-end seat 8 of the module assembly 12. By rotating the vertical adjusting screw 6, the module assembly 12 is rotated and adjusted along the X axis. At this time, the rotation axis of the module assembly 12 on the first adjusting bracket 4 is the vertical adjusting axis. A lens is installed at the front end of the module assembly 12 along the Y direction. The vertical adjusting axis is located close to the lens side, which can make the space occupied during front-end rotation adjustment smaller and reduce the impact on the modeling space.
[0041] A third ball joint 22 is installed at the top of the first adjusting bracket 4 along the Z direction, and spring pins 19 are provided at both ends of the bottom of the first adjusting bracket 4 along the Z direction. The third ball joint 22, the vertical adjusting screw 6, and the screw base 7 are pre-installed on the first adjusting bracket 4 to form the first adjusting bracket sub-assembly 13. The module sub-assembly 12 is installed into the first adjusting bracket sub-assembly 13 to form the module pre-assembly assembly 16.
[0042] A vertical translation adjustment screw 18 is installed on the inner side of the top of the second adjustment bracket 5 along the Z direction. The vertical translation adjustment screw 18 is adjusted by rotation along the Z direction. Two corresponding spring pin limiting grooves 20 are provided at the bottom of the second adjustment bracket 5 along the Z direction. During installation, a compression spring is installed on each of the two spring pins 19, pressing the third ball head seat 22 on the first adjustment bracket sub-assembly 13 into the vertical translation adjustment screw 18 on the second adjustment bracket 5. The two spring pins 19 are respectively installed in the two spring pin limiting grooves 20. By rotating the vertical translation adjustment screw 19, under the action of the compression spring, the module pre-assembly assembly 16 moves vertically along the Z direction within the second adjustment bracket 5.
[0043] A horizontal adjusting screw 17 is installed at one end of the second adjusting bracket 5 along the Y direction. The horizontal adjusting screw 17 and the vertical translation adjusting screw 18 are installed on the second adjusting bracket 5 to form the second adjusting bracket sub-assembly 14.
[0044] The module pre-assembly assembly 16 is installed in the second adjustment bracket sub-assembly 14. First, the compression spring 10 is inserted into the spring pin 19 in the module pre-assembly assembly 16. Then, the module pre-assembly assembly 16 is inserted into the spring pin limiting groove 20 on the second adjustment bracket sub-assembly 14 at an angle. After the compression spring 10 is pressed to the bottom, it is aligned with the upper vertical translation adjustment screw 18, and the third ball head seat 22 is aligned and pressed in. The other first ball head seat 8 of the module sub-assembly 12 is pressed into the horizontal adjustment screw 17. The horizontal adjustment screw 17 is offset on the second adjustment bracket 4. When the horizontal adjustment screw 17 is rotated, the module pre-assembly assembly 16 rotates horizontally with the upper vertical translation adjustment screw 18 as the pivot. Because the size of the spring pin limiting groove 20 is larger than the size of the spring pin 19, when the module pre-assembly assembly 16 rotates horizontally, both spring pins 19 simultaneously translate within the spring pin limiting groove 20, and the spring pin limiting groove 20 limits the rotation angle of the module pre-assembly assembly 16. At this time, the axis of the vertical translation adjustment screw 18 is the horizontal adjustment axis.
[0045] The installation methods of the horizontal adjusting screw 17 and the vertical translation adjusting screw 18 are the same as those of the vertical adjusting screw 6.
[0046] The vertical and horizontal adjustment axes are arranged close to their corresponding centers of symmetry, which reduces the space required for rotational adjustment. For headlight module 1, placing the vertical adjustment axis close to the module lens side further reduces the space required for front-end rotational adjustment.
[0047] By adjusting the vertical translation screw 18 and compressing the spring, the module's vertical translation within the lamp is achieved, optimizing the module's adjustment space compared to the original rotational adjustment. This compensates for the shading problem caused by rotational adjustment within the lamp. It also allows for smaller external mirrors to be concealed within the vehicle body, enabling more flexible styling designs.
[0048] The headlight module 1 achieves vertical rotation on the first adjustment bracket sub-assembly 13 via a vertical adjustment shaft. It also achieves vertical translation on the second adjustment bracket sub-assembly 14 via a vertical translation adjustment screw, and horizontal rotation on the second adjustment bracket sub-assembly 14 via a horizontal adjustment shaft. This is merely a preferred embodiment of the present invention and should not be construed as a limitation of the application. In another embodiment, vertical and horizontal rotation adjustments can be achieved between the first and second adjustment bracket sub-assemblies 13 and 14, while vertical translation adjustments can be achieved between the module and the first adjustment bracket sub-assembly 13.
[0049] In this embodiment, the light source is a surface-mount LED, which is integrated on the PCBA or on the heat sink and connected to the PCB board via metal wires. In other embodiments, other light source types can be selected according to actual needs.
[0050] 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.
