Description

Technical Field

[0001] This utility model relates to the field of lens technology, specifically to a lens structure that improves the whole-circle adhesive application. Background Technology

[0002] A camera lens is the core component that converts external scenes into optical images, and it is widely used in photography, security, industrial inspection, and other fields. It consists of optical lenses, mechanical structures, and electronic components. The optical lenses, such as aspherical lenses and achromatic cemented lenses, use complex curved surface designs and material combinations to correct aberrations and chromatic aberrations caused by light refraction, enabling precise light focusing and reproducing clear and realistic images. The lens barrel provides stable support for the lenses, and the internal precision focusing and zoom components can be adjusted by motors or manually to change the lens spacing, achieving focal length adjustment to meet different shooting distances and angles. However, existing lens structures have certain shortcomings.

[0003] A lens structure, such as one described in application number CN222545558U, includes: a lens barrel and a lens assembly housed within the lens barrel. The lens assembly has chamfered edges on both sides relative to the optical axis of the lens structure. The lens assembly includes at least two chamfered lenses, of which the lens closest to the object side of the lens structure is a first lens. The object side of the first lens has a first support portion. The lens assembly also includes a first structural ring that abuts against the first support portion. The first structural ring has a first non-chamfered portion and a first chamfered portion circumferentially connected. The shortest distance d from the inner ring surface of the first chamfered portion closest to the optical axis to the first lens along the direction parallel to the optical axis, and the shortest distance a between the chamfered portion of the first lens and the inner wall surface of the lens barrel along the direction perpendicular to the optical axis satisfy the following condition: 0.50 ≤ d / a ≤ 1.30. This invention solves the problem in the prior art of achieving both high image quality and small size in chamfered lenses. However, the lens combination and optical path design of this lens structure are unreasonable, which can easily produce aberrations and chromatic aberrations during light refraction, resulting in blurred images and edge distortion, which cannot meet the needs of high-resolution shooting. In addition, uneven glue distribution can cause the lens to be not firmly fixed, affecting the optical performance and stability of the lens, and even causing the lens to shift during use.

[0004] Therefore, in view of this, we studied and improved the existing structure to improve the lens structure by applying adhesive around the entire lens circumference. Utility Model Content

[0005] The purpose of this invention is to provide a lens structure with a complete lens ring adhesive application, in order to solve the problems mentioned in the background art, such as unreasonable lens combination and optical path design, which easily produce aberrations and chromatic aberrations during light refraction, resulting in blurred images and edge distortion, failing to meet the requirements of high-resolution shooting, and uneven adhesive distribution leading to unstable lens fixation, affecting the optical performance and stability of the lens, and even causing lens displacement during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lens structure for perfecting the full-circle adhesive application, comprising a mounting block and an auxiliary adhesive application mechanism. The auxiliary adhesive application mechanism is fixedly connected to the inner surface of the lens barrel, and the auxiliary adhesive application mechanism includes a magnetic block fixedly connected to the inner surface of the lens barrel. The magnetic block has an elastic cylinder inside, and a magnetic ring is adsorbed on the outer surface of the magnetic block. The inner surface of the magnetic ring has a slot, and a composite aspherical lens mechanism is fixedly connected to the inner surface of the magnetic ring.

[0007] Preferably, the composite aspherical lens mechanism includes a first aspherical lens fixedly connected to the inner surface of the magnetic ring, and a second aspherical lens fixedly connected to one side of the first aspherical lens, and an achromatic cemented lens fixedly connected to one side of the second aspherical lens.

[0008] Preferably, one end of the mounting block is fixedly connected to a lens barrel, and the inner wall of the lens barrel is fixedly connected to a hexagonal honeycomb skeleton.

[0009] Preferably, the hexagonal honeycomb skeleton is internally fixedly connected with reinforcing ribs, and the outer surface of the lens barrel is fixedly connected with an impact-resistant resin base layer.

[0010] Preferably, a buffer rubber layer is fixedly connected to the outer surface of the impact-resistant resin base layer, and a wear-resistant ceramic coating is fixedly connected to the outer surface of the buffer rubber layer.

[0011] Preferably, a thermally conductive silicone grease layer is fixedly connected to the outer surface of the wear-resistant ceramic coating, and a heat dissipation channel is fixedly connected to the outer surface of the thermally conductive silicone grease layer.

[0012] Preferably, the inner surface of the heat dissipation channel is provided with heat dissipation holes, and the outer surface of the heat dissipation channel is fixedly connected with heat dissipation fins.

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

[0014] 1. This utility model, through the setting of an auxiliary dispensing mechanism, adopts a dual structure of "magnetic pre-positioning + mechanical precision locking" to update the lens assembly installation process. The magnetic block and magnetic ring rely on the strong magnetic force generated by opposite magnetic poles to automatically attract and align upon approach, eliminating the need for complex manual calibration and achieving millisecond-level rapid positioning, which greatly improves assembly efficiency. This pre-positioning method allows operators to operate with one hand and easily fix the composite aspherical lens mechanism to the lens barrel, significantly reducing the installation difficulty. It not only ensures accurate dispensing trajectory but also greatly enhances the connection strength of the components, effectively resisting external vibration and impact. Even in a severely bumpy environment, it can ensure a stable connection between the lens and the lens barrel, extending the lens's service life.

[0015] 2. This utility model, through the setting of the composite aspherical lens mechanism 3, forms a unique curved surface design, breaking the optical limitations of traditional spherical lenses. Compared with traditional lenses, the three components work together to correct various aberrations and chromatic aberrations, enabling light to converge precisely on the imaging plane, improving the overall image clarity by 70%, effectively eliminating blurring and distortion at the edges, and achieving sharp image quality from the center to the edge. Whether it is distant details or wide-angle scenes, it can restore true colors and clear outlines.

[0016] 3. This utility model, through the setting of hexagonal honeycomb skeleton and reinforcing ribs, the two complement each other to ensure that the lens can maintain the precise positional relationship of the lens group under complex working conditions such as severe vibration and external impact, avoiding imaging shift and blurring caused by structural deformation, and providing a solid physical guarantee for high-quality imaging.

Detailed Implementation

[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] like Figures 1-2As shown, a lens structure for perfecting the entire lens circumference adhesive application includes a mounting block 1 and an auxiliary adhesive application mechanism 2. The auxiliary adhesive application mechanism 2 is fixedly connected to the inner surface of the mounting block 1. The auxiliary adhesive application mechanism 2 includes a magnetic block 201 fixedly connected to the inner surface of the mounting block 1. An elastic cylinder 202 is disposed inside the magnetic block 201, and a magnetic ring 203 is adsorbed onto the outer surface of the magnetic block 201. A slot 204 is formed on the inner surface of the magnetic ring 203, and a... In the composite aspherical lens mechanism 3, the magnetic block 201 and the magnetic ring 203 attract each other through the magnetic force generated by the opposite magnetic poles, completing the initial rapid positioning of the lens assembly. After attraction, the elastic cylinders 202 evenly distributed inside the magnetic block 201 are deformed by the magnetic force and are inserted into the corresponding slots 204 on the magnetic ring 203. After the elastic cylinders 202 are reset, a mechanical lock is formed, ensuring that the parts do not shift during dispensing. This not only improves the dispensing position accuracy but also enhances the connection strength of the components and avoids loosening caused by vibration.

[0024] like Figure 3 As shown, the composite aspherical lens mechanism 3 includes a first aspherical lens 301 fixedly connected to the inner surface of the magnetic ring 203, and a second aspherical lens 302 fixedly connected to one side of the first aspherical lens 301. An achromatic cemented lens 303 is fixedly connected to one side of the second aspherical lens 302. The first aspherical lens 301 and the second aspherical lens 302 effectively reduce aberrations through a special curved surface design, making the light focus more accurately. The achromatic cemented lens 303 can eliminate the chromatic aberration of light of different wavelengths. The combination of the three improves the image clarity of the lens by 70% compared with traditional lenses, and the edge imaging is also sharper and clearer.

[0025] Furthermore, a lens barrel 4 is fixedly connected to one end of the mounting block 1, and a hexagonal honeycomb skeleton 5 is fixedly connected to the inner wall of the lens barrel 4. A reinforcing rib 6 is fixedly connected inside the hexagonal honeycomb skeleton 5, and an impact-resistant resin base layer 7 is fixedly connected to the outer surface of the lens barrel 4. The hexagonal honeycomb skeleton 5 is embedded in the inner wall of the lens barrel 4 to form a mesh support structure. The reinforcing rib 6 is distributed at the key nodes of the hexagonal honeycomb skeleton 5, which helps to improve stability and evenly distribute external forces. When the lens is squeezed or collided, the reinforcing rib 6 further enhances the structural strength and effectively prevents the lens from deforming due to external forces, thus affecting imaging.

[0026] Furthermore, a buffer rubber layer 8 is fixedly connected to the outer surface of the impact-resistant resin base layer 7, and a wear-resistant ceramic coating 9 is fixedly connected to the outer surface of the buffer rubber layer 8. A thermally conductive silicone grease layer 10 is fixedly connected to the outer surface of the wear-resistant ceramic coating 9, and a heat dissipation channel 11 is fixedly connected to the outer surface of the thermally conductive silicone grease layer 10. The wear-resistant ceramic coating 9 has high hardness and can effectively resist scratches, improving wear resistance. The buffer rubber layer 8 has good elasticity and absorbs impact force when the lens is hit. The impact-resistant resin base layer 7 provides basic impact resistance. The three protective layers work together to greatly improve the lens's drop resistance and reduce the risk of lens breakage and lens barrel damage.

[0027] Furthermore, heat dissipation holes 12 are provided on the inner surface of the heat dissipation channel 11, and heat dissipation fins 13 are fixedly connected to the outer surface of the heat dissipation channel 11. The heat generated by the lens operation is conducted to the heat dissipation channel 11 through the thermally conductive silicone grease layer 10, and then dissipated into the air by the heat dissipation fins 13. The heat dissipation holes 12 in the heat dissipation channel 11 maintain airflow to accelerate heat exchange.

[0028] Working principle: When using this lens structure with full-circle adhesive application, the magnetic ring 203 containing the first aspherical lens 301, the second aspherical lens 302, and the achromatic cemented lens 303 is first attracted to the magnetic ring 203 inside the mounting block 1, completing the initial positioning of the composite aspherical lens mechanism 3 and the lens barrel 4. Then, the elastic cylinder 202 inside the magnetic block 201 of the auxiliary adhesive application mechanism 2 is deformed by magnetic force and gets stuck into the slot 204 of the magnetic ring 203 to form a mechanical lock. Then, the adhesive is evenly applied along the edge of the magnetic ring 203. The adhesive is applied, and the thermally conductive silicone grease layer 10 conducts the heat generated by the electronic components inside the lens barrel 4 to the heat dissipation channel 11, which is then quickly dissipated through the heat dissipation holes 12 and the heat dissipation fins 13. Finally, when the lens is subjected to external impact, the wear-resistant ceramic coating 9 protects the lens barrel surface from scratches, and the buffer rubber layer 8 further attenuates the impact energy. Combined with the mechanical dispersion design of the hexagonal honeycomb skeleton 5 and the reinforcing ribs 6, the stability of the composite aspherical lens mechanism 3 and the lens barrel 4 after installation is ensured. This is the working principle of the lens structure with full-circle adhesive application.
