Description

Technical Field

[0001] This utility model relates to the technical field of vehicle lighting sensing mechanisms, specifically a gyroscope-based sensor mechanism for vehicle lighting. Background Technology

[0002] With the rapid development of the automotive industry, automotive lighting systems play a crucial role in ensuring driving safety and enhancing the driving experience. Modern cars not only need to provide clear and appropriate lighting under various road conditions and environmental circumstances, but also require intelligent and adaptive functions to cope with complex and ever-changing driving scenarios. For example, when driving on highways, high beams are needed to provide a longer and brighter field of vision; when driving on curves, meeting oncoming traffic, or encountering pedestrians, the beam angle and brightness need to be adjusted promptly to avoid dazzling other road users while ensuring the driver's own safety. These diverse needs place increasingly higher demands on the control and adjustment technology of automotive headlights.

[0003] Early car headlights were mostly manually adjustable, requiring drivers to adjust the headlight beam angle based on vehicle load, road conditions, and other factors. This method was cumbersome and couldn't adapt to dynamic changes during vehicle movement. For example, when a heavy load in the trunk raised the front of the car, the driver might not notice and manually adjust the headlight angle in time, potentially leading to insufficient illumination or glare for other vehicles, increasing the risk of accidents. To overcome the shortcomings of manual adjustment, some vehicles were equipped with automatic headlight adjustment systems based on simple sensors (such as vehicle height sensors). However, these systems were relatively limited in function, only making coarse adjustments based on limited changes in vehicle posture. They couldn't accurately perceive the impact of various driving states, such as acceleration, deceleration, steering, and incline / descent, on headlight illumination requirements. For instance, when a vehicle was turning at high speed, relying solely on the vehicle height sensor couldn't accurately adjust the headlight beam direction, creating a blind spot on the inside of the curve and affecting the driver's observation of road conditions.

[0004] Therefore, a gyroscope-based sensor mechanism for vehicle lights is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a gyroscope-based sensor mechanism for vehicle lights to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gyroscope sensor mechanism for vehicle lights, comprising a lamp body, a mounting platform for controlling its rotation, a control module, and a gyroscope sensor located below the lamp body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, during vehicle operation, uses a control module and gyroscope sensor to sense the vehicle's driving conditions in real time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a gyroscope sensor mechanism for vehicle lights, including a lamp body 1. Below the lamp body 1 is a mounting platform 2 for controlling its rotation, a control module 3, and a gyroscope sensor 4. A fixing frame 5 is mounted on the outer wall of the mounting platform 2. A fixing shaft 6 is mounted inside the fixing frame 5. A rotating frame 7 is rotatably mounted at the lower end of the fixing shaft 6. A mounting frame 8 is mounted inside the rotating frame 7. A rotating seat 9 is mounted inside the mounting frame 8. A rotating wheel 10 is rotatably mounted inside the rotating seat 9. A fixing ring 11 is mounted on one side of the rotating wheel 10. The fixing ring 11 is mounted on the lamp body 1. A follower protrusion 12 is mounted on one side of the fixing ring 11. The bottom of the 12 has a limiting tooth groove 122. Below the follower protrusion 12, there is a drive component to control its swing. Below the mounting frame 8, there is a drive mechanism. By controlling the drive gear 13 in the drive component in real time, the follower protrusion 12 is driven to swing, thereby driving the lamp body 1 and the fixing ring 11 to follow the rotating wheel 10 to adjust the angle inside the rotating seat 9, so that the vehicle can adapt to the lighting needs of different steep road sections. By controlling the steering motor 17 in the drive mechanism to drive the coupling 16 to drive the rotating frame 7 and the mounting frame 8 to rotate, thereby driving the rotating seat 9, the rotating wheel 10 and the lamp body 1 below to adjust the angle left and right together, thereby controlling the headlight to automatically adjust the angle when turning.

[0024] like Figure 2 and 3 As shown, the drive assembly includes a drive gear 13. One side of the drive gear 13 meshes with one side of the inner wall of the limiting tooth groove 122. A connecting shaft 14 is installed inside the drive gear 13. One end of the connecting shaft 14 is rotatably mounted on the mounting frame 8, and the other end of the connecting shaft 14 is mounted on a drive motor 15. The drive motor 15 is mounted on the mounting frame 8. When the drive motor 15 rotates, it drives the drive gear 13 to rotate. The drive gear 13 drives the follower protrusion 12 to swing. The follower protrusion 12 is mounted on the fixed ring 11, and the fixed ring 11 is fixed on the lamp body 1. Therefore, the swing of the follower protrusion 12 will drive the lamp body 1 and the fixed ring 11 to move together. At the same time, the follower rotating wheel 10 on one side of the fixed ring 11 is rotatably mounted inside the rotating seat 9, thereby realizing the headlight angle adjustment control.

[0025] like Figure 2 and 3As shown, the drive mechanism includes a coupling 16. The upper end of the coupling 16 is mounted on the mounting frame 8, and the lower end of the coupling 16 is mounted on a steering motor 17. The outer wall of the coupling 16 is mounted inside the rotating frame 7. The control module 3 and the gyroscope sensor 4 are both mounted on the mounting platform 2. The coupling 16 is rotatably mounted inside the rotating frame 7, and the bottom of the steering motor 17 is mounted on the mounting platform 2. When the vehicle turns, the gyroscope sensor 4 detects the change in the vehicle's yaw rate and transmits the data to the control module 3. The control module 3 calculates the angle that the headlights need to be adjusted left and right based on this data. The control module 3 sends a command to the drive mechanism, and the steering motor 17 in the drive mechanism starts. The bottom of the steering motor 17 is mounted on the mounting platform 2, and its output shaft is connected to the rotating frame 7 through the coupling 16. The coupling 16 is rotatably mounted inside the rotating frame 7, and at the same time, the upper end of the coupling 16 is connected to the mounting frame 8, thereby realizing the adjustment of the headlight angle.

[0026] like Figure 2 As shown, the inner wall of the rotating seat 9 is matched in size with the outer wall of the rotating wheel 10. Both the rotating seat 9 and the rotating wheel 10 are made of stainless steel.

[0027] The working principle is as follows: In actual use, during the vehicle's driving process, the gyroscope sensor 4 senses various motion states of the vehicle in real time, such as yaw rate, pitch rate, roll rate, etc. These sensing data are transmitted to the control module 3. The control module 3 analyzes and processes the data transmitted from the gyroscope sensor 4 to determine the current driving condition of the vehicle, such as whether it is driving on a curve, going up or down a slope, accelerating or decelerating. Based on different driving conditions, the control module 3 determines the adjustment direction and magnitude of the headlights to achieve adaptive lighting and meet the lighting needs under different driving conditions.

[0028] When the vehicle travels on inclines or declines, the vehicle's pitch angle changes. The gyroscope sensor 4 detects this change and transmits the data to the control module 3. The control module 3 calculates the headlight adjustment angle based on a preset algorithm and sends a command to the drive assembly. The drive motor 15 in the drive assembly starts working. The drive motor 15 is mounted on the mounting frame 8, and its output shaft is connected to the drive gear 13 via a connecting shaft 14. The drive gear 13 meshes with the limiting groove 122 at the bottom of the follower protrusion 12. When the drive motor 15 rotates, it drives the drive gear 13 to rotate, which in turn drives the follower protrusion 12 to swing. 2. The lamp body 1 is fixed on the fixed ring 11. Therefore, the swing of the follower protrusion 12 will drive the lamp body 1 and the fixed ring 11 to move together. At the same time, the follower protrusion 12 on one side of the fixed ring 11 swings on the rotating wheel 10. The rotating wheel 10 is installed inside the rotating seat 9. Both the rotating seat 9 and the rotating wheel 10 are made of stainless steel. The two fit well and rotate smoothly. The swing of the follower protrusion 12 makes the lamp body 1 and the fixed ring 11 adjust their angles inside the rotating seat 9 with the rotating wheel 10. This allows the headlight's illumination angle to adapt to the changes in uphill and downhill road sections, ensuring that the road ahead is properly illuminated when the vehicle is going uphill or downhill.

[0029] When the vehicle turns, the gyroscope sensor 4 detects the change in the vehicle's yaw rate and transmits the data to the control module 3. The control module 3 calculates the required left and right adjustment angle for the headlights and sends a command to the drive mechanism. The steering motor 17 in the drive mechanism starts. The bottom of the steering motor 17 is mounted on the mounting platform 2, and its output shaft is connected to the rotating frame 7 via a coupling 16. The coupling 16 is rotatably mounted inside the rotating frame 7, and its upper end is connected to the mounting frame 8. When the steering motor 17 rotates, it drives the rotating frame 7 to rotate via the coupling 16. The headlight is equipped with a mounting frame 8, which contains a rotating seat 9, a rotating wheel 10, and a lamp body 1 below. Therefore, the rotation of the rotating frame 7 will cause the rotating seat 9, the rotating wheel 10, and the lamp body 1 to adjust their angles left and right together, thereby controlling the headlight to automatically adjust its angle to follow the vehicle's turn, preventing blind spots on the inside of curves and improving driving safety. The headlight uses a gyroscope sensor mechanism to monitor the vehicle's driving status in real time through a gyroscope sensor 4. The control module controls the drive components and drive mechanism based on the monitoring data, accurately adjusting the headlight angle to effectively improve the performance of the automotive lighting system and driving safety.

[0030] Example 2: Figure 2 and 5As shown, to further improve the stability of the headlights when turning, a guide seat 18 is installed on the top of the mounting platform 2. Two guide grooves 19 are formed on the top of the guide seat 18, and guide wheels 20 are slidably installed inside each guide groove 19. A connecting rod 21 is installed on one side of each guide wheel 20, and both connecting rods 21 are mounted on the rotating frame 7. When the headlights adjust their angle left and right as the vehicle turns, to improve their stability, the guide seat 18 is installed on the top of the mounting platform 2, and two guide grooves 19 are formed on the top of the guide seat 18. Two connecting rods 21 are installed on the rotating frame 7, and a guide wheel 20 is installed at one end of each connecting rod 21. The guide wheel 20 is slidably installed in the corresponding guide groove 19. When the rotating frame 7 drives the headlights to rotate left and right, the connecting rod 21 moves accordingly, and the guide wheel 20 rolls within the guide groove 19. The guide groove 19 guides and limits the guide wheel 20, making the rotation of the rotating frame 7 more stable, thereby ensuring the stability of the headlights during turning and preventing the headlights from shaking and affecting the lighting effect or causing damage to other components.
