Technical Field
[0001] This utility model relates to the field of automotive lenses, and in particular to a high-precision automotive lens for controlling light ripples. Background Technology
[0002] With the rapid development of automotive intelligence and autonomous driving technologies, vehicle-mounted cameras, as core components of environmental perception systems, undertake critical tasks such as road monitoring, obstacle recognition, and driver status detection. Their imaging quality directly affects the accuracy of algorithmic decisions and driving safety, especially under complex lighting conditions such as tunnel entrances and exits, strong backlighting, and nighttime oncoming traffic.
[0003] Existing automotive lenses are typically installed on vehicles for shooting and recording the driving environment. However, current automotive lenses usually rely on a fixed aperture to control the amount of light entering the camera. When faced with different lighting conditions, they often fail to provide optimal image quality. In strong light, too much light can easily lead to overexposure and loss of detail, while in low light, insufficient light can easily lead to increased image noise, decreased sharpness, and affect image quality.
[0004] Therefore, it is necessary to design a high-precision vehicle-mounted lens that can adjust the amount of light entering the camera by adjusting the position of the adjustment plate according to the light intensity, so as to facilitate the adjustment of the aperture size, improve the shooting clarity and image quality, adapt to the shooting needs under different lighting conditions, and use flexible and convenient light control. Utility Model Content

The fourth lens is installed on the inner side of the rear of the lens barrel, and the fourth lens is located behind the third lens. The fifth lens is installed at the rear of the lens barrel. A spacer is connected to the inner side of the lens barrel, and the spacer contacts the fourth lens. The rear cover is threadedly connected to the rear of the lens barrel.
[0008] In a preferred embodiment of this invention, the diameter of the front cover is larger than the diameter of the rear cover.
[0009] In a preferred embodiment of the present invention, the adjustment assembly includes a motor, a gear set, a rotating frame, an adjustment plate, and a slide plate. The motor is connected to the right side of the front cover, and the rotating frame is rotatably connected to the rear of the front cover. A gear set is provided between the output shaft of the motor and the rotating frame. Multiple adjustment plates are movably connected to the rotating frame, and a slide plate is connected to the inner side of the middle of the front cover.

[0010] In a preferred embodiment of this invention, the adjusting plates are evenly distributed along the rotating frame.
[0011] In a preferred embodiment of the present invention, the gear set includes a gear and a gear ring. The gear is connected to the output shaft of the motor, and the gear ring is connected to the outside of the rotating frame. The gear and the gear ring mesh with each other.
[0012] The beneficial effects of this utility model are as follows: 1. By rotating the frame, the adjustment plate moves and unfolds, allowing light to enter the lens barrel. The position of the adjustment plate can be adjusted to regulate the amount of light entering the lens. At the same time, by controlling the aperture, the camera can be adjusted to adjust the position of the adjustment plate according to the light intensity. This makes it easy to adjust the aperture size, improve the clarity and image quality of the shot, adapt to the shooting needs under different lighting conditions, and is flexible and convenient to use.
[0013] 2. This utility model uses a lens barrel and mounting ring to install a vehicle-mounted lens, and then lifts the shock absorber to contact the vehicle for installation and fixation.

[0022] A high-precision automotive lens for controlling light ripples, such as Figures 1-5As shown, the system includes a shock absorber 1, a mounting ring 2, a vehicle-mounted lens, and an adjustment assembly. The upper part of the shock absorber 1 is connected to the mounting ring 2, which houses the vehicle-mounted lens. The vehicle-mounted lens includes a lens barrel 3, a front cover 4, a first lens 5, a second lens 6, a light control unit 7, a third lens 8, a fourth lens 9, a fifth lens 10, a spacer 11, and a rear cover 12. The lens barrel 3 is snapped onto the mounting ring 2. The front part of the lens barrel 3 is threadedly connected to the front cover 4, and the front part of the front cover 4 is connected to the first lens 5. The second lens 6 is snapped onto the inner side of the front part of the lens barrel 3, and the light control unit 7 is connected to the middle of the lens barrel 3. The second lens 6 contacts the light control point 7. The third lens 8 is installed on the inner rear side of the lens barrel 3, and the third lens 8 contacts the light control point 7. The fourth lens 9 is installed on the inner rear side of the lens barrel 3, and the fourth lens 9 is located behind the third lens 8. The fifth lens 10 is installed at the rear of the lens barrel 3. The spacer 11 is connected to the inner side of the lens barrel 3, and the spacer 11 contacts the fourth lens 9. The rear cover 12 is connected to the rear side of the lens barrel 3 by threads. The diameter of the front cover 4 is larger than the diameter of the rear cover 12. The vehicle lens is provided with an adjustment component for adjusting the incoming light.
[0023] like Figure 2 , Figure 4 and Figure 5 As shown, the adjustment assembly includes a motor 13, a gear set 14, a rotating frame 15, adjustment plates 16, and a sliding plate 17. The motor 13 is connected to the right side of the front cover 4, and the rotating frame 15 is rotatably connected to the rear of the front cover 4. The gear set 14 is provided between the output shaft of the motor 13 and the rotating frame 15. The gear set 14 includes a gear and a gear ring. The gear is connected to the output shaft of the motor 13. The gear ring is connected to the outer side of the rotating frame 15. The gear and the gear ring mesh with each other. Six adjustment plates 16 are movably connected to the rotating frame 15. The adjustment plates 16 are evenly distributed along the rotating frame 15. The sliding plate 17 is connected to the inner side of the middle of the front cover 4. All adjustment plates 16 are slidably connected to the sliding plate 17.
[0024] When a high-precision automotive lens is required on a vehicle, this device can be used. The second lens 6 is snapped into the lens barrel 3 for installation. Next, the front cover 4 is brought into contact with the lens barrel 3, and then the front cover 4 is rotated to move it for installation. Then, the third lens 8, the fourth lens 9, and the fifth lens 10 are installed, with the fourth lens 9 contacting the spacer 11. Next, the rear cover 12 is brought into contact with the lens barrel 3, and then the rear cover 12 is rotated to move it for installation. Finally, the lens barrel 3 is snapped into the mounting ring 2, thereby installing the automotive lens. The diameter of the front cover 4 is larger than the diameter of the rear cover 12. The shock absorber 1 is then lifted and installed in contact with the vehicle for fixation. During vehicle operation, the shock absorber 1 dampens the vibration of the vehicle-mounted lens, thus enabling the device to be used in the vehicle while simultaneously damping the lens during travel, preventing wear or damage, extending the lens's lifespan, and improving ease of use. Subsequently, the light intake is adjusted according to the light intensity, and the motor 13 is started. The motor 13 drives the gear to rotate, and the gear meshes with the gear ring, causing the rotation... The rotating frame 15 rotates, causing the adjusting plate 16 to move and unfold along the sliding plate 17, allowing light to enter the lens barrel 3. The position of the adjusting plate 16 is then adjusted to regulate the amount of light entering the lens. After reaching a suitable position, the motor 13 is turned off. The adjusting plate 16 is then evenly distributed along the rotating frame 15 and adjusted via the control aperture 7. Subsequently, a vehicle-mounted lens is used for shooting and recording. This allows for adjusting the position of the adjusting plate 16 according to light intensity to regulate the amount of light entering the lens, facilitating adjustment of the aperture size, improving image clarity and quality, and making it suitable for various applications. To meet the imaging needs under different lighting conditions, it is flexible and convenient to use. The compact arrangement of the lenses before and after the aperture reduces the system size while meeting the requirement of a large field of view. Aspherical lenses are used near the aperture to correct edge aberrations, reducing the dependence on the mechanical precision of the aperture and reducing the number of lenses. After use, the motor 13 operates in reverse, causing the gear to rotate in the opposite direction. The gear and the gear ring mesh with each other, causing the rotating frame 15 to rotate in the opposite direction. This causes the adjusting plate 16 to move and close along the slide plate 17. Then, the motor 13 is turned off, and the vehicle-mounted lens is turned off.
