Description

Technical Field

[0001] The utility model relates to the technical field of camera lens structures, in particular to a radiation-resistant camera lens structure. Background Art

[0002] The camera lens is a crucial component of any camera, directly impacting its image quality and performance. It primarily consists of a frame and lens. The lens acts as a light-modulating element in the optical path, and its material, shape, and coating determine its optical properties. Common lens types include spherical and aspherical lenses, with aspherical lenses offering advantages in reducing distortion and improving clarity. The frame primarily connects and supports the camera lens, securing it at the very front of the camera assembly.

[0003] Generally speaking, lenses use optical principles to focus light onto a camera's sensor, producing a clear image. Furthermore, high-quality lenses increase the amount of light entering, thereby improving image clarity and color reproduction. Different types of lenses can meet diverse shooting needs, from wide-angle to macro photography. Furthermore, coating and other processing technologies can enhance lens transmittance and wear resistance, thereby extending the lifespan of camera lenses or expanding their applicability.

[0004] Based on this, Chinese patent CN112291464B discloses a camera lens manufacturing method, camera lens, and electronic device. The method includes: making positioning marks on a sapphire sheet, the positioning marks being used to mark the preset positions and windows of multiple lenses; making a colored film from a PET film sheet, the colored film including multiple sub-films corresponding to the multiple lenses, and the colored film being a translucent film with a gradient color; pre-cutting the colored film according to the positioning marks; attaching the pre-cut colored film to a sapphire sheet to form a lens group, so that the multiple sub-films and the multiple lenses overlap one by one; and cutting the lens group to obtain multiple camera lenses. In other words, this method can avoid directly setting pattern effects on the camera lens body, thereby avoiding the problem of wasting the camera lens body if the pattern effect setting fails, thereby increasing the production cost of the camera module, and thus reducing the production cost of the camera module.

[0005] In addition, another Chinese patent CN115442508B also discloses an optical lens and a camera including the optical lens. The patent discloses an optical lens, which also includes a camera housing, a connecting sleeve configured on the camera housing, a drive ring rotatably mounted on one end of the connecting sleeve, a connecting column configured on the inner circumference of the connecting sleeve, and the connecting column passing through the drive ring and connected to an annular plate. When the body of this lens is installed on the camera, raindrops are not easy to adhere to the lens body, so that dust contained in raindrops is not easy to adhere to the lens body, thereby preventing the camera from imaging blur and improving the use effect of the camera. When the lens body needs to be disassembled or installed, it is only necessary to rotate the drive ring. During the rotation process, the drive ring uses the linkage assembly to connect or disengage multiple plug-in blocks from the corresponding plug-in holes, making it more convenient to disassemble and install without the need for tools.

[0006] However, the aforementioned camera lens structure still suffers from the technical issue of poor radiation resistance. Specifically, in some specialized applications, such as the nuclear field, many workplaces are inaccessible to workers due to high radiation levels. Therefore, to provide real-time visibility into the actual conditions within these locations, a convenient method is to add a detection lens. However, since conventional camera lenses are not treated for radiation resistance, they quickly age and fail when used in high-radiation environments. Utility Model Content

[0007] Based on this, it is necessary to provide a radiation-resistant camera lens structure to address the technical problem of how to improve the radiation resistance of the camera lens structure.

[0026] Please also refer to Figures 1 to 3 The utility model provides a radiation-resistant camera lens structure including: a radiation-resistant lens 1, an intermediate connecting ring 2, a threaded connecting ring 3, a support seat 4 and a camera module 5; the radiation-resistant lens 1 is connected to the intermediate connecting ring 2, and the intermediate connecting ring 2 is respectively connected to the radiation-resistant lens 1 and the threaded connecting ring 3; the threaded connecting ring 3 is connected to the support seat 4, and the camera module 5 is arranged between the radiation-resistant lens 1 and the support seat 4.

[0027] Specifically, in the radiation-resistant camera lens structure of the present invention, the camera module 5, whose service life is easily affected by high ambient radiation, is positioned between the radiation-resistant lens 1 and the support base 4. The radiation-resistant lens 1 is a hemispherical cover structure made of radiation-resistant glass. It isolates and protects the camera module 5, which captures and transmits images, from radiation, allowing it to operate for extended periods in various high-radiation environments. More specifically, the camera module 5 can be any commercially available product; of course, other camera devices can also be selected based on practical needs. The support base 4 can be an aluminum alloy or lead structure, with the camera modules 5 spaced apart thereon. Furthermore, the threaded connecting ring 3 can also be an aluminum alloy or lead ring-shaped structure, with threads formed on both its inner and outer sides. One thread connects it to the support base 4, and the other connects it to the intermediate connecting ring 2. Furthermore, the outer wall of the threaded connecting ring 3 can be evenly spaced with grooves to increase friction on its outer side, facilitating assembly and disassembly. The intermediate connecting ring 2 is used to connect the radiation-resistant lens 1 to the intermediate connecting ring 2. Preferably, the intermediate connecting ring 2 is made of a radiation-resistant rubber material. Firstly, the rubber material itself facilitates the secure attachment of the radiation-resistant lens 1 thereto via methods such as hot-melt welding. Secondly, the radiation-resistant rubber material also provides radiation protection, thereby reducing radiation penetration and harm to the human body and the environment. It also exhibits excellent flexibility. It can be seen from this that the radiation-resistant camera lens structure of the present invention can enhance the camera's ability to resist radiation through reasonable structural design, so that it can be used in a strong radiation environment for a long time.

[0028] Furthermore, the radiation-resistant lens 1 can be coated on ordinary glass to enhance the radiation resistance of the glass lens itself by coating its surface with a radiation-resistant film. The aforementioned radiation-resistant film, also known as anti-radiation film or anti-electromagnetic radiation film, is a thin film material with special functions, primarily used to reduce or block electromagnetic waves, ultraviolet radiation, and other radiation that can harm the human body or interfere with electronic devices.

[0029] More specifically, one of the main failure mechanisms of lenses made of ordinary glass is that they are gradually stained under the influence of various strong radioactive radiation situations. For example, after high-energy particles and high-energy radiation act on the glass, color centers are formed in the glass. It is generally believed that the oxygen ion vacancies in the glass combine with free electrons to form color centers and produce a series of absorption peaks in the ultraviolet, visible light and infrared regions, making the glass darker and stained. In order to prevent the glass from being stained by radiation, the formation of structural defects can be reduced and the glass structure network can be strengthened. That is, other anions are added to fill the oxygen ion vacancies and to prevent the excited electrons from falling into the structural vacancies and to capture free electrons. For optical glass with a wide range of composition changes, it is most appropriate to add certain variable valence metal ions to capture the released electrons to prevent jade and radiation staining. The most commonly used method is to add oxidizing agents, such as Ce to the glass. 4+ Ions can capture electrons released by radiation and become Ce 3+ , so that the glass does not form color centers. The change in spectral transmittance caused by the change in the valence state of cerium ions is only in the ultraviolet region and basically does not affect the transmittance in the visible light region.

[0030] Furthermore, the intermediate connecting ring 2 comprises a heat-sealable connection portion 201 and a seat connection portion 202. The heat-sealable connection portion 201 is disposed within the seat connection portion 202. The heat-sealable connection portion 201 is connected to the lower periphery of the radiation-resistant lens 1, while the seat connection portion 202 surrounds the heat-sealable connection portion 201 and is connected to the threaded connecting ring 3. Specifically, the heat-sealable connection portion 201 may be a structure with a certain degree of resilience, for example, made of radiation-resistant rubber with a U-shaped annular cross-section. This resilient structure has the advantage of accommodating manufacturing tolerances of the radiation-resistant lens 1. Generally, the inner diameter of the heat-sealable connection portion 201 is slightly smaller than the minimum manufacturing control diameter of the radiation-resistant lens 1. Thus, even if the peripheral dimensions of the radiation-resistant lens 1 are at the lower tolerance limit, it can still be reliably connected to the intermediate connecting ring 2 through heat-sealable connection or other means. Similarly, the seat body connecting portion 202 is used to connect it to the threaded connecting ring 3, and the two can be connected to each other as a whole through in-mold injection molding or the like.

[0031] Furthermore, the support base 4 comprises a base 401, an inner connecting portion 402, a guide connecting portion 403, and a raised support frame 404. The inner connecting portion 402 is disposed on the base 401 and is connected to the threaded connection ring 3. The guide connecting portion 403 is disposed on the other side of the base 401 relative to the inner connecting portion 402. The raised support frame 404 is disposed within the inner connecting portion 402, and the camera module 5 is disposed on the raised support frame 404. Specifically, the inner connecting portion 402 is provided with threads for connecting it to the threaded connection ring 3. The guide connecting portion 403 is a hollow structure, and its internal hollow cavity communicates with the cavity enclosed between the support base 4 and the radiation-resistant lens 1, thereby connecting external cables to the camera module 5 disposed therein. The raised support frame 404 may be a connecting frame structure made of brass or copper alloy, and is used to lift the bottom of the camera module 5 away from the inner connecting portion 402 , thereby reducing its interference with the imaging of the camera module 5 .

[0032] Furthermore, the camera module 5 comprises a main control module 501, a housing structure 502, a camera unit 503, and a plurality of fill lights 504. The main control module 501 is disposed within the housing structure 502, which is connected to the elevated support frame 404. The camera unit 503 is disposed on the housing structure 502, and a plurality of fill lights 504 are evenly distributed around the camera unit 503, each of which is connected to the housing structure 502. The camera unit 503 and each of the fill lights 504 are electrically connected to the main control module 501. Specifically, the main control module 501 is provided with the necessary components for controlling the camera unit 503 and is built into the housing structure 502. The camera unit 503 is used for processing such as translucent imaging. The fill lights 504 are used to provide fill light within the imaging range of the camera unit 503 to improve the clarity of the image.

[0033] In summary, the present invention provides a radiation-resistant camera lens structure that includes a radiation-resistant lens 1, an intermediate connecting ring 2, a threaded connecting ring 3, a support seat 4, and a camera module 5. The radiation-resistant lens 1 is connected to the intermediate connecting ring 2, which connects the radiation-resistant lens 1 and the threaded connecting ring 3. The threaded connecting ring 3 is connected to the support seat 4, and the camera module 5 is disposed between the radiation-resistant lens 1 and the support seat 4. The radiation-resistant lens 1 is a hemispherical cover structure with radiation-resistant properties, made of glass raw materials that have undergone radiation-resistant treatment. It isolates the camera module 5, which captures and transmits image content, from radiation to protect it, and allows the camera module 5 to be used for long periods of time in various environments with high radiation intensity. Therefore, the present invention provides a radiation-resistant camera lens structure that solves the technical problem of how to improve the radiation resistance of a camera lens structure.
