Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to an automobile headlight with adjustable angle. Background Art

[0002] As a key component for ensuring safety during nighttime driving and in adverse weather conditions, car headlights' performance directly affects the driver's observation and judgment of road conditions. With the continuous development of automotive technology and the increasing demand for driving safety and driving experience, car headlight technology is also undergoing continuous innovation.

[0003] Traditional automotive headlights are mostly fixed, with no adjustable angle after installation, or they offer only very limited adjustment capabilities, such as simple manual fine-tuning of the angle up and down, with low adjustment accuracy. In complex real-world driving scenarios, these fixed-angle headlights struggle to meet diverse lighting needs. For example, when a vehicle is driving on a curve, the fixed headlight angle prevents the light from following the vehicle's direction, resulting in insufficient illumination on the inside of the curve. This makes it difficult for the driver to clearly observe road conditions, pedestrians, or obstacles in that area, significantly increasing driving risks. On uphill and downhill roads, the vehicle's pitch changes, and fixed-angle headlights can cause the light to tilt upward or downward excessively. On uphill roads, the light may illuminate the sky, failing to effectively illuminate the road ahead. On downhill roads, the light may overbrighten the nearby road surface while limiting the illumination range in the distance, affecting the driver's ability to predict road conditions. Therefore, we propose an adjustable-angle automotive headlight to address these issues. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] like Figure 1-5 As shown:

[0031] An angle-adjustable automobile headlight comprises a lampshade 101;

[0032] The lamp body 102 is located at the center of the through hole of the lampshade 101 and is used to provide lighting for the road. The diameter of the through hole opened in the center line of the lampshade 101 is larger than the outer diameter of the lamp body 102.

[0033] There are two sets of L-shaped plates 103, which are fixedly mounted on the surface of the lampshade 101. The adaptive front lighting system controller is fixedly mounted on the surface of one set of L-shaped plates 103. The surface of the L-shaped plates 103 has multiple sets of mounting holes.

[0034] The annular disk 104 is provided between the two sets of L-shaped plates 103 and is mounted on the two sets of L-shaped plates 103 via a bearing sleeve;

[0035] The rotating mechanism 2 is mounted on a set of L-shaped plates 103 and is used to drive the annular disk 104 to rotate. The rotating mechanism 2 includes a motor 201 fixedly mounted on one set of L-shaped plates 103 via a mounting plate, and a spur gear 202 fixed to the output end of the motor 201. An annular gear plate 203 meshing with the spur gear 202 is fixedly mounted on the outer surface of the annular disk 104. A rectangular opening is opened near the spur gear 202 on one set of L-shaped plates 103, and the spur gear 202 can rotate within the rectangular opening of the L-shaped plate 103.

[0036] An adjustment mechanism 3 is provided between the annular disk 104 and the headlight body 102 and is used to adjust the angle of the headlight body 102. The adjustment mechanism 3 includes an adjustment shaft 301 fixed to both sides of the surface of the headlight body 102. The other end of the adjustment shaft 301 is rotatably connected to the annular disk 104 via a bearing. An adjustment frame 302 is fixedly mounted on the surface of the adjustment shaft 301. A support frame 303 is fixedly mounted on the surface of the annular disk 104 near the adjustment frame 302. A first electric telescopic push rod 304 is hingedly connected between the support frame 303 and the adjustment frame 302 via a hinge shaft.

[0037] A locking mechanism 4 for preventing the annular disk 104 from moving is installed on one set of L-shaped plates 103. The locking mechanism 4 includes a second electric telescopic push rod 401 fixed to one side of the L-shaped plate 103 by a square plate. An extrusion block 402 is fixedly installed on the output end of the second electric telescopic push rod 401. A movable block 404 slides on one side of the extrusion block 402. A spring 403 is fixedly installed between the movable block 404 and the extrusion block 402. A sliding groove adapted to the movable block 404 is provided on one side of the extrusion block 402. The movable block 404 can slide in the sliding groove provided in the extrusion block 402.

[0038] A conductive rotating disk 106 is provided on the rear side of the lamp body 102 . A symmetrically arranged connecting frame 105 is fixedly mounted on the rotating end of the conductive rotating disk 106 . The other end of the connecting frame 105 is fixedly connected to the annular disk 104 .

[0039] In this embodiment, when using adjustable headlights, a steering wheel angle sensor (not shown) detects the driver's steering operation, including steering direction, steering angle, and speed, while the vehicle is driving. These signals are transmitted to an adaptive front-lighting system controller (not shown). Simultaneously, a vehicle speed sensor provides feedback on the vehicle's driving speed.

[0040] The adaptive front-lighting system controller combines steering angle and vehicle speed information to calculate the target angle at which the lamp needs to be deflected left or right. This adjustment range is usually between ±5° and ±15°, and the specific value is set according to the calibration of different vehicle models.

[0041] The adaptive front-lighting system controller then sends a drive signal to the motor 201 of the rotating mechanism 2, starting the motor 201 and driving the spur gear 202 at the output end to rotate. The spur gear 202 engages with the annular gear plate 203 on the periphery of the annular plate 104, converting the rotational motion of the motor 201 into the circular motion of the annular plate 104. The rectangular opening on the L-shaped plate 103 provides rotation space for the spur gear 202 to prevent interference. The rotation of the annular plate 104 causes the lamp body 102 to rotate synchronously.

[0042] In addition, the adjustment shafts 301 on both sides of the lamp body 102 can be converted from horizontal to vertical adjustment;

[0043] At the same time, the adaptive front-lighting system controller also sends a signal to the first electric telescopic push rod 304. The extension and retraction of the first electric telescopic push rod 304 drives the adjustment frame 302, which drives the adjustment shaft 301 to rotate synchronously, thereby driving the lamp body 102 to rotate left and right. The rotation of the lamp body 102 around the adjustment shaft 301 can achieve the follow-up steering of the light toward the inside of the curve, ensuring that there is no blind spot in the curved area.

[0044] When the vehicle exits the curve and resumes straight driving, the steering wheel angle sensor will feedback a zero angle signal, and the adaptive front lighting system controller will then control the motor 201 to rotate in the reverse direction, so that the annular disk 104 and the first electric telescopic push rod 304 are reset to the initial position;

[0045] like Figure 3 As shown: If the vehicle travels in a straight line for a long time, the locking mechanism 4 will be activated: the second electric telescopic push rod 401 extends, driving the squeezing block 402 to move, and the squeezing block 402 squeezes and fixes one side of the annular disk 104, thereby locking the position of the annular disk 104 and ensuring its stability, thereby achieving the position locking of the lamp body 102;

[0046] While the extrusion block 402 is squeezing the annular disk 104, the movable block 404 is in contact with the annular disk 104 and compresses the spring 403. The spring 403 acts as a buffer when the extrusion block 402 and the annular disk 104 are squeezed. The buffering force achieves rigid locking to prevent angular deviation caused by vehicle bumps, thereby further improving the flexibility and practicality of the structure.

[0047] When the vehicle is traveling uphill or downhill, the pitch of the vehicle body changes, causing the direction of the light to shift. At this time, the vehicle's body attitude sensor (such as a gyroscope) will detect the pitch angle of the vehicle and transmit a signal to the adaptive front lighting system controller when the front of the vehicle is raised when going uphill or lowered when going downhill.

[0048] like Figure 4 As shown: the adaptive front-lamp system controller calculates the target angle that the lamp needs to be adjusted up and down according to the pitch angle to ensure that the light beam is always focused on the road ahead and avoids illuminating the sky or nearby areas too brightly. The adaptive front-lamp system controller sends a telescopic instruction to the first electric telescopic push rod 304 of the adjustment mechanism 3. The two ends of the first electric telescopic push rod 304 are respectively hinged to the support frame 303 and the adjustment frame 302. When the first electric telescopic push rod 304 is extended, the adjustment frame 302 is pushed to rotate upward around the adjustment shaft 301; when the push rod is shortened, the adjustment frame 302 is pulled to rotate downward around the adjustment shaft 301. The adjustment shaft 301 is connected to the annular disk 104 through a bearing to ensure smooth rotation. The adjustment frame 302 is fixedly connected to the adjustment shaft 301 and is connected to the headlight body 102. Its rotation directly drives the headlight body 102 to tilt up and down around the adjustment shaft 301, thereby realizing the pitch correction of the light illumination angle, thereby completing the adjustment of the up and down angles.

[0049] The conductive rotating disk 106 on the rear side of the headlight body 102 rotates with the annular disk 104. The sliding and telescopic contact conductive structure ensures that the circuit is continuously connected during the left and right and up and down adjustments of the headlight body 102, thereby preventing the problem of cable entanglement or breakage. The other end of the conductive rotating disk 106 is installed and connected to the designated component of the vehicle.

[0050] The diameter of the central through-hole of the lampshade 101 is larger than the outer diameter of the lamp body 102, which provides sufficient space for the left-right and up-and-down rotation of the lamp body 102, avoiding mechanical interference with the lampshade 101. The L-shaped plate 103 is fixed to the vehicle body through multiple sets of mounting holes, providing rigid support for the annular disk 104, lampshade 101, rotating mechanism 2, and adjustment mechanism 3, ensuring the stability of the overall structure and no shaking during adjustment.

[0051] This solution receives the vehicle's driving status signal through the adaptive headlight system controller, and links the rotating mechanism 2 and the adjusting mechanism 3, thereby solving the problem of insufficient lighting of traditional fixed or limited adjustment function car headlights in complex driving scenarios. When the vehicle is driving on a curve, the headlight body 102 follows the vehicle's turning to illuminate the area inside the curve, avoiding the blind spot of the curve lighting and reducing driving risks. On uphill and downhill sections, the up and down angle adjustment of the headlight body 102 is realized to prevent the light from being excessively raised or lowered, ensuring sufficient lighting of the road ahead, and facilitating the driver to predict road conditions.

[0052] It should be noted that the steering wheel angle sensor and the body posture sensor are both installed on the vehicle body;

[0053] It should be noted that the electrical equipment involved in this product is powered by the car's power supply. The power connection method of each electrical device is an existing mature technology and is well known to people in this field. It will not be described in detail here.

[0054] Meanwhile, the contents of the adaptive front lighting system controller not described in detail in this specification belong to the prior art known to those skilled in the art.

[0055] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
