Description

Technical Field

[0001] This utility model relates to the field of resin lens technology, and in particular to a thin and light curved lens. Background Technology

[0002] In the consumer electronics field, devices such as smartphones and tablets are constantly pursuing higher imaging quality and thinner and lighter designs. Thin and light curved lenses can effectively reduce the size of optical modules while improving imaging resolution and optical performance, meeting consumers' dual needs for portability and functionality. In addition, in the automotive electronics field, sensors such as vehicle cameras and LiDAR have extremely high requirements for the precision and thinness of optical components. The application of thin and light curved lenses can significantly improve the performance of these devices and meet the high-precision sensing requirements of intelligent driving.

[0003] In existing technologies, traditional convex lenses are prone to dust contamination when idle, which can significantly affect the lens's optical performance and observation results. Dust particles adhere to the lens surface, forming tiny obstructions that cause light scattering and absorption, thereby reducing the lens's transmittance and image quality. In addition, the presence of dust may also cause light diffraction and interference phenomena, further affecting the image's clarity and contrast. This contamination not only reduces the performance of the optical system but may also shorten the lens's lifespan and increase maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a thin and light curved lens.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a thin and light curved lens, including a convex lens, a fixed plate fixed to the bottom of the convex lens, a limiting groove formed on the surface of the fixed plate, a round pin slidably connected inside the limiting groove, a sealing tooth fixed to the bottom of the round pin, a plurality of sealing teeth arranged in a ring array and slidably connected to each other, a sliding pin fixed to the bottom of the sealing tooth, a rotating disk rotatably connected to the circumference of the sealing tooth, a sliding groove formed inside the rotating disk, and the sliding groove slidably connected to the surface of the sliding pin.

[0006] Preferably, a protective ring is nested around the convex lens, a connecting ring is fixed to the inner wall of the protective ring, and a convex ring is fixed to the inner wall of the connecting ring. The height of the convex ring is higher than the height of the protective ring. In the prior art, the surface of traditional lenses is easily scratched or damaged. This damage not only affects the aesthetics of the lens but also seriously affects its optical performance. Scratches on the lens surface interfere with the normal propagation of light, leading to increased light scattering and reflection, thereby reducing the lens's transmittance and image quality. In some high-precision optical applications, such as microscopes, telescopes, or precision optical instruments, such scratches may even cause blurred images and reduced resolution, seriously affecting the equipment's performance and measurement accuracy. To address these issues, this invention uses a protective structure. The lens is protected by the protective ring, and the convex ring further elevates the convex lens to prevent it from being bumped or knocked, thus protecting the convex lens and avoiding damage to the lens that could affect the equipment's performance and measurement accuracy.

[0007] Preferably, the sealing tooth surface is covered with a shaped rubber sleeve, which has good flexibility and elasticity, and can fit tightly with adjacent parts or sealing surfaces to fill tiny gaps and irregular surfaces, thereby significantly improving the sealing effect.

[0008] Preferably, the inner wall of the slide groove is provided with a trapezoidal slide groove, and the two ends of the slide pin are fixed with step blocks. This structure can provide good self-locking performance. When the step blocks slide in the trapezoidal slide groove, due to the inclined surface design of the trapezoid, they will generate a large contact area and friction with the slide groove, thereby avoiding loosening or falling off during the sliding process. It can ensure that the slide remains stable and will not be displaced due to external force or vibration.

[0009] Preferably, the surface of the connecting ring is provided with honeycomb grooves. The structure of the honeycomb grooves can effectively disperse stress and avoid stress concentration. When subjected to external force, the geometry of the honeycomb grooves can evenly distribute the stress to the entire surface of the connecting ring, thereby significantly improving the fatigue resistance and fracture resistance of the connecting ring.

[0010] Preferably, the surface of the rotating disk is provided with anti-slip texture. The anti-slip structure design can significantly improve the user's experience, providing a more stable and reliable grip during use, thereby enhancing the user's experience.

[0011] Beneficial effects:

[0012] 1. In existing technologies, traditional convex lenses are prone to dust contamination when idle, which significantly affects their optical performance and observation results. Dust particles adhere to the lens surface, forming tiny obstructions that cause light scattering and absorption, thereby reducing the lens's transmittance and image quality. Furthermore, the presence of dust can also cause diffraction and interference, further affecting image sharpness and contrast. This contamination not only reduces the performance of the optical system but may also shorten the lens's lifespan and increase maintenance costs. To address these issues, this invention employs a novel sealing structure, ensuring that the convex lens is sealed when in use. The user can rotate the rotating disk, causing the limiting groove to rotate. Driven by the limiting groove, the round pin moves backward, causing the sliding pin to expand the sealing teeth backward. Under the limiting of the sliding groove, the sliding pin slides along the groove, causing the sealing teeth to continuously expand outward, thus opening the sealing teeth and allowing the convex lens to be used. After the convex lens is idle, the operator can rotate the rotating disk in the opposite direction, causing the sealing teeth to move in the opposite direction along the limiting groove, thereby retracting the sealing teeth and sealing the convex lens. This provides dust protection for the convex lens, reducing dust contamination and improving the user experience.

[0013] 2. In the prior art, the surface of traditional lenses is easily scratched or damaged. This damage not only detracts from the lens's aesthetics but also severely affects its optical performance. Scratches on the lens surface interfere with the normal propagation of light, leading to increased light scattering and reflection, which in turn reduces the lens's transmittance and image quality. In some high-precision optical applications, such as microscopes, telescopes, or precision optical instruments, these scratches may even cause blurred images and reduced resolution, seriously affecting the equipment's performance and measurement accuracy. To address these issues, this invention utilizes a protective structure. The lens is protected by a protective ring, and the convex ring further elevates the convex lens to prevent it from being bumped or knocked, thus protecting the convex lens and avoiding damage that could affect the equipment's performance and measurement accuracy.

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0024] Reference Figure 1-5A thin and light curved lens includes a convex lens 1, a fixed disk 2 fixed to the bottom of the convex lens 1, a limiting groove formed on the surface of the fixed disk 2, a circular pin slidably connected inside the limiting groove, a sealing tooth 201 fixed to the bottom of the circular pin, multiple sealing teeth 201 arranged in a circular array and slidably connected to each other, a sliding pin 204 fixed to the bottom of the sealing tooth 201, a rotating disk 202 rotatably connected to the circumference of the sealing tooth 201, a sliding groove 203 formed inside the rotating disk 202, and the sliding groove 203 slidably connected to the surface of the sliding pin 204. In the prior art, traditional convex lenses are easily contaminated by dust when idle, which can significantly affect the optical performance and observation effect of the lens. Dust particles adhere to the lens surface, forming tiny obstructions, causing light scattering and absorption, thereby reducing the lens's transmittance and image quality. In addition, the presence of dust may also cause light diffraction and interference phenomena, further affecting the image sharpness and contrast. Contamination not only reduces the performance of optical systems but may also shorten the lifespan of lenses and increase maintenance costs. To address these issues, this invention employs a novel sealing structure. When the convex lens 1 needs to be used, the user can rotate the rotating disk 202, causing the limiting groove to rotate. Driven by the limiting groove, the round pin moves backward, causing the sliding pin 204 to extend the sealing teeth 201 backward. Limited by the sliding groove 203, the sliding pin 204 slides along the sliding groove 203, causing the sealing teeth 201 to continuously expand outward, thus opening the sealing teeth 201 and allowing the convex lens 1 to be used. When the convex lens 1 is not in use, the operator can rotate the rotating disk 202 in the opposite direction, causing the sealing teeth 201 to move in the opposite direction along the limiting groove, thereby retracting the sealing teeth 201 and sealing the convex lens 1. This provides dust protection for the convex lens 1, reducing dust contamination and improving the user experience.

[0025] A protective ring 3 is nested around the convex lens 1. A connecting ring 301 is fixed to the inner wall of the protective ring 3. A convex ring 302 is fixed to the inner wall of the connecting ring 301. The height of the convex ring 302 is higher than that of the protective ring 3. A plastic sleeve is fitted on the surface of the sealing tooth 201. A trapezoidal groove 203 is opened on the inner wall of the slide 203. A step block is fixed at both ends of the sliding pin 204. A honeycomb groove is opened on the surface of the connecting ring 301. An anti-slip texture is opened on the surface of the rotating disk 202.

[0026] The working principle of this utility model is as follows: When the user needs to use the convex lens 1, the user can rotate the rotating disk 202, which causes the limiting groove to rotate. Therefore, the round pin moves backward under the drive of the limiting groove, which causes the sliding pin 204 to drive the sealing tooth 201 to expand backward. Under the limitation of the sliding groove 203, the sliding pin 204 slides along the sliding groove 203, which causes the sealing tooth 201 to continuously expand outward, thereby opening the sealing tooth 201 and allowing the convex lens 1 to be used. After the convex lens 1 is idle, the operator can rotate the rotating disk 202 in the opposite direction, which causes the sealing tooth 201 to move in the opposite direction along the limiting groove, thereby retracting the sealing tooth 201 and sealing the convex lens 1. This achieves dust protection for the convex lens 1, thereby reducing dust contamination of the convex lens 1 and improving the user experience.
