Abstract

This invention relates to the field of automotive lighting, and discloses an auxiliary low beam micro-adjustment structure for automotive lighting. The auxiliary low beam micro-adjustment structure includes a light source, an X-axis adjustment component, and a Y-axis adjustment component. The light source is mounted on the reflector of the automotive lighting headlight. The X-axis adjustment component adjusts the X-axis position of the light source on the reflector to adjust the X-axis offset of the light reflection path. The Y-axis adjustment component adjusts the Y-axis position of the light source on the reflector to adjust the Y-axis offset of the light reflection path. This invention achieves adjustment of the light source position through the X-axis and Y-axis adjustment components, which is more conducive to aligning the low beam cutoff line. The high and low beam reflectors and the auxiliary low beam reflector can be made into a single structure, with a relatively simple mold structure and virtually no core-pulling structure. This saves on reflector mold costs, avoids excessive gaps between the high and low beam reflectors and the auxiliary low beam reflector, and also avoids dimming interference.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0034] This embodiment provides a structure for adjusting the low beam of a vehicle headlight, such as... Figures 1-3 As shown, the headlight auxiliary low beam fine-tuning structure includes a light source, an X-axis adjustment component 1, and a Y-axis adjustment component 2.

[0035] The light source is mounted on the reflector bowl 100 of the vehicle headlight. The X-axis adjustment component 1 is used to adjust the X-axis position of the light source on the reflector bowl 100 to adjust the X-axis offset of the light reflection path of the light source. The Y-axis adjustment component 2 is used to adjust the Y-axis position of the light source on the reflector bowl 100 to adjust the Y-axis offset of the light reflection path of the light source.

[0036] The position of the light source can be adjusted by adjusting the X-axis adjustment component 1 and the Y-axis adjustment component 2, which is more conducive to aligning the position of the low beam cutoff line. The high beam and low beam reflectors and the auxiliary low beam reflector can be made into an integrated structure. The mold structure is relatively simple and there is basically no core pulling structure. While saving the cost of reflector molds, it can also avoid the gap between the high beam and low beam reflectors and the auxiliary low beam reflector being too large, and it can also avoid dimming interference. The structure is simple, the cost is low, and the space occupied is small.

[0037] To facilitate adjustment of the light source position, the auxiliary low beam micro-adjustment structure of the vehicle headlight may optionally include a circuit board 3 and a slide 4. The light source is set on the circuit board 3, the circuit board 3 is slidably set on the slide 4 along the X direction by the X-direction adjustment component 1, and the slide 4 is slidably set on the reflector bowl 100 along the Y direction by the Y-direction adjustment component 2.

[0038] To facilitate the sliding of the circuit board 3 along the X-direction on the slide block 4 via the X-direction adjustment component 1, optionally, the X-direction adjustment component 1 includes an X-direction guide rail 11, which is fixedly connected to the slide block 4, and the circuit board 3 is slidably disposed on the X-direction guide rail 11. In this embodiment, two X-direction guide rails 11 are spaced apart, and the circuit board 3 is disposed between the two X-direction guide rails 11, with both sides of the circuit board 3 extending into the two X-direction guide rails 11 respectively, which improves the smoothness of sliding.

[0039] To facilitate adjustment of the sliding distance of the circuit board 3 on the slide block 4, the X-axis adjustment assembly 1 may optionally include a first fixing bracket 12 and a first adjusting screw 23. The first fixing bracket 12 is fixedly connected to the reflector bowl 100, one end of the first adjusting screw 23 abuts against the circuit board 3, and the other end of the first adjusting screw 23 is threadedly connected to the first fixing bracket 12. To facilitate the reset of the circuit board 3, the X-axis adjustment assembly 1 may optionally include a first elastic element with the extension direction along the X direction. One end of the first elastic element is fixedly connected to the slide block 4, and the other end of the first elastic element is fixedly connected to the circuit board 3. In this embodiment, the first elastic element can be a spring, which is readily available and inexpensive.

[0040] To facilitate the sliding of the slide block 4 along the Y direction on the reflector bowl 100 via the Y-axis adjustment component 2, optionally, the Y-axis adjustment component 2 includes a Y-axis guide rail 21, which is fixedly connected to the reflector bowl 100, and the slide block 4 is slidably disposed on the Y-axis guide rail 21. In this embodiment, two Y-axis guide rails 21 are spaced apart, and the slide block 4 is disposed on two X-axis guide rails 11, resulting in uniform force distribution and improved sliding stability.

[0041] To facilitate adjustment of the sliding distance of the slide block 4 on the reflector bowl 100, the Y-axis adjustment assembly 2 may optionally include a second fixing bracket 22 and a second adjusting screw 23. The second fixing bracket 22 is fixedly connected to the reflector bowl 100, one end of the second adjusting screw 23 abuts against the slide block 4, and the other end of the second adjusting screw 23 is threadedly connected to the second fixing bracket 22. To facilitate the reset of the slide block 4, the Y-axis adjustment assembly 2 may optionally include a second elastic element with its extension direction along the Y direction. One end of the second elastic element is fixedly connected to the reflector bowl 100, and the other end of the second elastic element is fixedly connected to the slide block 4. In this embodiment, the second elastic element can be a spring, which is readily available and inexpensive.

[0042] To facilitate precise automatic control of the light source's position, motors can be installed on the first and second adjusting screws 23 for precise control. The corresponding motors can be remotely controlled via a remote control. Although this increases the cost, it also improves the operating speed and simplifies the operation.

[0043] To further improve the dimming accuracy, optionally, a main reflector 200 is provided inside the reflector bowl 100, and a reflective stripe plate 5 is adjustablely mounted on the main reflector 200. To facilitate adjustment of the position of the reflective stripe plate 5 relative to the main reflector 200, optionally, a fulcrum screw 51, an up / down dimming screw 52, ​​and a left / right dimming screw 53 are provided on the reflective stripe plate 5. One end of each of the fulcrum screw 51, the up / down dimming screw 52, ​​and the left / right dimming screw 53 is fixedly connected to the reflective stripe plate 5, and the other end is threaded to the reflector bowl 100.

[0044] The auxiliary low beam micro-adjustment structure for vehicle headlights provided in this embodiment has a light source mounted on the reflector bowl 100 of the headlight. An X-axis adjustment component 1 adjusts the X-axis position of the light source on the reflector bowl 100 to adjust the X-axis offset of the light reflection path. A Y-axis adjustment component 2 adjusts the Y-axis position of the light source on the reflector bowl 100 to adjust the Y-axis offset of the light reflection path. The adjustment of the light source position via the X-axis and Y-axis adjustment components 1 and 2 is more conducive to aligning the low beam cutoff line. The high and low beam reflectors and the auxiliary low beam reflector can be made into a single integrated structure, with a relatively simple mold structure and virtually no core-pulling structure. This saves on reflector mold costs, avoids excessive gaps between the high and low beam reflectors and the auxiliary low beam reflector, and prevents dimming interference. The structure is simple, low-cost, and occupies little space.
