Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a headlight sensor bracket for automobiles. Background Technology

[0002] The bracket incorporates a high-precision light sensor (photosensor) that can monitor ambient light intensity in real time. When it detects oncoming vehicle headlights or changes in ambient light, the sensor transmits a signal to a voltage regulator, which dynamically controls the light transmittance by adjusting the voltage of the glass dimming plate.

[0003] According to the patent titled "A Car Headlight Sensor Bracket" (Patent Publication No.: CN212654266U, Patent Publication Date: 2021-03-05), it includes a high beam bracket and a low beam bracket. The high beam bracket and low beam bracket each have a high beam slot and a low beam slot respectively in their middle portions. A light sensor is embedded in the upper end of the high beam bracket. The outer end of a fixing frame is fixedly connected to the high beam bracket by bolts. A mounting plate is fixedly connected to the lower part of the high beam bracket. A component box is mounted on the top of the mounting plate, and a base plate is provided at the bottom of the component box. A cooling fan, power supply, switch, and voltage regulator are mounted on the upper part of the base plate. By using a light sensor in conjunction with a voltage regulator and a glass dimming plate, the intensity of the car headlights can be automatically adjusted according to changes in ambient light. This solves the problem of component wear caused by repeated movement and adjustment of mechanically moving light shields. Adjustment is convenient, installation is convenient, and setting operation is simple and convenient.

[0004] Based on the aforementioned existing technology, the current automotive headlight sensor bracket still has the following problems: the existing light sensor is easily covered by contaminants such as dust, mud, and snow, which makes it impossible to accurately sense changes in ambient light. In rainy or muddy conditions, the sensor may misjudge the environment as dark and incorrectly turn on the headlights, or conversely, the lights may not be turned on in time due to dirt. Therefore, this utility model provides an automotive headlight sensor bracket. Utility Model Content

[0025] The lifting unit 21 is located inside the bracket 1 and is used to enable the sensor to be retracted into the bracket 1 for cleaning.

[0026] The cleaning unit 22 is located on the outside of the bracket 1 and includes a mounting rail 221 fixedly installed on one side of the bracket 1. The mounting rail 221 has a track groove 222 inside. A sliding plate 223 is slidably installed inside the track groove 222. A sponge block 224 is fixedly installed at the bottom of the sliding plate 223. A cleaning cloth 225 is wrapped around the surface of the sponge block 224. The sponge block 224 and the cleaning cloth 225 are inserted into the bracket 1 by the linear movement of the sliding plate 223 to clean the sensor.

[0027] In this embodiment, a linkage seat 226 is fixedly installed below one end of the sliding plate 223, and a linkage groove 227 is provided inside the linkage seat 226.

[0028] The second motor 228, model KV3SF-8521F-WR, is electrically connected to an external power supply and is operated by a human-controlled control panel. The second motor 228 drives the first motor 219 to rotate. The first motor 219 drives the drive column 2210 to slide inside the linkage groove 227, realizing the reciprocating movement of the linkage seat 226. The linkage seat 226 drives the sliding plate 223 to reciprocate synchronously. The sliding plate 223 drives the sponge block 224 and the cleaning cloth 225, so that the sponge block 224 and the cleaning cloth 225 enter the interior of the bracket 1 through the through groove on the bracket 1, so that the cleaning cloth 225 contacts the light sensor 214, thereby cleaning the light sensor 214.

[0029] In this embodiment, a mounting plate 2211 is fixedly installed on one side of the bracket 1, and a second motor 228 is fixedly installed at the bottom of the mounting plate 2211. A rotating rod 229 is fixedly installed through the mounting plate 2211 at the output end of the second motor 228. A drive column 2210 is fixedly installed above one end of the rotating rod 229, and the drive column 2210 slides inside the linkage groove 227.

[0030] The second motor 228 drives the rotation of the column 2210 via the rotating rod 229, forming a stable crank-slider mechanism with the linkage groove 227, ensuring the linear stroke accuracy of the sliding plate 223.

[0031] In this embodiment, the lifting unit 21 includes a limiting rod 211 fixedly installed on the bottom inner side of the bracket 1, and a sliding sleeve rod 212 slidably installed on the surface of the limiting rod 211. A fixing plate 213 is fixedly installed at the bottom end of the sliding sleeve rod 212, and a light sensor 214 is fixedly installed on the top of the fixing plate 213. The light sensor 214 is lifted and lowered by the sliding sleeve rod 212 on the surface of the limiting rod 211 so that the light sensor 214 can be retracted into the bracket 1 for cleaning. A first motor 219 is fixedly installed on one side of the bracket 1, and a connecting frame 218 is fixedly installed through the output end of the first motor 219 through the bracket 1. A turntable 216 is fixedly installed at one end of the connecting frame 218, and a vortex groove 217 is opened inside the turntable 216. A linkage column 215 is fixedly installed below one side of the sliding sleeve rod 212, and the linkage column 215 is located inside the vortex groove 217 to adapt to sliding, thereby realizing the lifting and lowering of the sliding sleeve rod 212.

It is electrically connected to an external power supply and can be opened and closed by a human-operated control panel. The first motor 219 drives the connecting frame 218 to rotate, and the connecting frame 218 drives the turntable 216 to rotate. The turntable 216 slides inside the vortex groove 217 through the linkage column 215, realizing the downward movement of the sliding sleeve rod 212. The light sensor 214 is moved into the interior of the bracket 1 through the fixing plate 213.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, the first motor 219 drives the connecting frame 218 to rotate, which in turn drives the turntable 216 to rotate. The turntable 216 slides inside the vortex groove 217 via the linkage column 215, causing the sliding sleeve rod 212 to move downward. The fixed plate 213 moves the light sensor 214 into the interior of the bracket 1. The second motor 228 drives the first motor 219 to rotate, which in turn drives the drive column 2210 to slide inside the linkage groove 227, causing the linkage seat 226 to reciprocate. The linkage seat 226 drives the sliding plate 223 to reciprocate synchronously. The sliding plate 223 drives the sponge block 224 and the cleaning cloth 225 to enter the interior of the bracket 1 through the through groove on the bracket 1, so that the cleaning cloth 225 comes into contact with the light sensor 214, thereby cleaning the light sensor 214.
