Description

Technical Field

[0001] The present invention relates to the technical field of optical lenses, and specifically to a heating de-icing and defogging structure for an optical lens and a usage method thereof. Background Art

[0002] In cold or humid environments, optical lenses are widely used, such as in security monitoring, vehicle-mounted cameras, outdoor shooting equipment, etc.; currently, the main de-icing and defogging methods for optical lenses are as follows: mechanical scraping method, where a simple mechanical structure similar to a windshield wiper scrapes on the lens surface to remove ice and fog; chemical reagent coating method, where anti-fog agents, de-icing agents and other chemical reagents are coated on the lens surface, and the properties of the chemical substances are used to prevent or eliminate ice and fog.

[0003] However, these existing de-icing and defogging methods have many drawbacks; mechanical scraping, due to direct contact with the lens surface, is extremely likely to produce scratches during repeated scraping, seriously damaging the optical performance of the lens; chemical reagent coating not only requires manual operation and is a cumbersome process, but also some chemical reagents are corrosive, and long-term use will erode the coating of the lens and even the lens material, so a heating de-icing and defogging structure for an optical lens and a usage method thereof are proposed.

[0006] (2) Technical Solutions

[0007] To achieve the above purposes of efficient de-icing and defogging and protecting the lens, the present invention provides the following technical solutions: a heating de-icing and defogging structure for an optical lens, including a lens frame, a lens is movably installed inside the lens frame, and a de-icing and defogging mechanism is arranged inside the lens frame;

[0008] The de-icing and defogging mechanism includes a limit bracket, a lens bracket, a temperature sensor, a humidity sensor, a transparent graphene heating film, electrodes, a ring heating element, a fastening bracket, a plug post, a limit gasket and a control module. A limit bracket is snap-fitted inside the spectacle frame. A lens bracket is fixedly installed inside the limit bracket. A temperature sensor and a humidity sensor are fixedly installed on the left side of the lens bracket. A transparent graphene heating film is installed on the outer surface of the lens. Electrodes are fixedly installed inside the transparent graphene heating film. A ring heating element is snap-fitted on the outer surface of the lens. A fastening bracket is movably installed on the left side of the spectacle frame. A plug post and a limit gasket are fixedly installed on the right side of the fastening bracket. A control module is fixedly installed on the outer surface of the spectacle frame.

[0009] Preferably, the left side of the lens bracket fits against the right side of the lens, and both the temperature sensor and the humidity sensor fit against the right side of the lens.

[0010] Preferably, the transparent graphene heating film is closely attached to the outer surface of the left side of the lens through a high-temperature and high-light-transmission adhesive, and the thickness of the transparent graphene heating film is 0.01 mm - 0.05 mm.

[0011] Preferably, two electrodes are fixedly installed inside the transparent graphene heating film, one of which is a positive electrode plate and the other is a negative electrode plate.

[0012] Preferably, a ring snap-fitting groove is formed on the outer side of the lens, the ring heating element is snap-fitted inside the ring snap-fitting groove, and two cable connection terminals are fixedly installed on the outside of the ring heating element.

[0013] Preferably, the fastening bracket is inserted into the left side of the spectacle frame through two plug posts fixedly installed on the right side, and the right side of the limit gasket fits against the outer surface of the left side of the lens.

[0014] Preferably, the temperature sensor, the humidity sensor, the electrodes and the ring heating element are all electrically connected to the control module.

[0015] A usage method of a heating de-icing and defogging structure for an optical lens, including the heating de-icing and defogging structure of the optical lens, further includes the following steps:

[0016] S1. Ambient parameter monitoring: The temperature sensor and the humidity sensor continuously monitor the temperature and humidity data of the environment around the lens, and transmit the data to the control module in real time;

[0017] S2. Determine whether to start heating: The control module analyzes and judges the received temperature and humidity data. If the humidity data reaches or exceeds the set humidity threshold and the temperature data is higher than 0°C, it is determined that the lens surface may fog up, and the control module sends an energization instruction to the electrodes of the transparent graphene heating film to make the transparent graphene heating film start working. If the temperature data is lower than or equal to 0°C, regardless of the humidity data, it is determined that the lens surface may freeze, and the control module sends energization instructions to the electrodes of the transparent graphene heating film and the ring heating element at the same time, and the two work together.

[0018] S3. De-ice and defog by heating: After the transparent graphene heating film is energized, it quickly generates heat by using its good electro-thermal conversion performance, and the generated heat is evenly transmitted to the lens surface, increasing the lens temperature, thereby dispelling fog or melting ice. Since its thickness is only 0.01mm - 0.05mm and it fits closely, it can transfer heat efficiently while minimizing the impact on the optical performance of the lens. When the ring heating element also receives the energization instruction, it surrounds the outside of the lens and assists in heating from the edge part, enhancing the overall heating effect and accelerating the de-icing speed.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a heating, de-icing and defogging structure and usage method for an optical lens, having the following beneficial effects:

[0021] 1. The heating, de-icing and defogging structure and usage method for this optical lens, by adopting a transparent graphene heating film and a ring heating element, avoid the direct contact and potential damage to the lens surface by the traditional mechanical scraping method. When the humidity data reaches or exceeds the set threshold and the temperature is higher than 0°C, the control module sends an energization instruction to the transparent graphene heating film, which quickly generates heat by using its good electro-thermal conversion performance and evenly transfers the heat to the lens surface to dispel fog without leaving scratches. This non-contact heating and defogging method not only effectively protects the optical performance of the lens, but also improves the reliability and service life of the device.

[0022] 2. The heating, de-icing and defogging structure and usage method for this optical lens, in a cold environment, when the temperature is lower than or equal to 0°C, the control module starts the transparent graphene heating film and the ring heating element at the same time. The ring heating element surrounds the outside of the lens and assists in heating from the edge part, enhancing the overall heating effect and accelerating the melting of ice. Compared with the traditional chemical reagent coating method, this method does not require manual operation, reducing the risk of erosion of the lens coating and material by corrosive chemical substances. In addition, the structure is compactly designed and stably installed, ensuring efficient operation and long-term stability in harsh environments. Brief description of the drawings

The ring heating element 307 is snap-fitted on the outer surface of the lens 2. The fastening bracket 308 is movably installed on the left side of the frame 1. The plug post 309 and the limit gasket 310 are fixedly installed on the right side of the fastening bracket 308. The control module 311 is fixedly installed on the outer surface of the frame 1.

[0033] A usage method of a heating de-icing and defogging structure of an optical lens, including the heating de-icing and defogging structure of the optical lens, further includes the following steps:

[0034] S1. Ambient parameter monitoring: The temperature sensor 303 and the humidity sensor 304 continuously monitor the temperature and humidity data of the environment around the lens 2, and transmit the data to the control module 311 in real time;

[0035] S2. Judging whether to start heating: The control module 311 analyzes and judges the received temperature and humidity data; if the humidity data reaches or exceeds the set humidity threshold and the temperature data is higher than 0°C, it is determined that fog may form on the lens surface, and the control module 311 sends an energization instruction to the electrode 306 of the transparent graphene heating film 305 to make the transparent graphene heating film 305 start to work; if the temperature data is lower than or equal to 0°C, regardless of the humidity data, it is determined that ice may form on the lens surface, and the control module 311 sends energization instructions to the electrode 306 of the transparent graphene heating film 305 and the ring heating element 307 at the same time, and the two work together;

[0036] S3. Heating de-icing and defogging: After the transparent graphene heating film 305 is energized, it quickly generates heat by virtue of its good electro-thermal conversion performance, and the generated heat is evenly transmitted to the surface of the lens 2, raising the temperature of the lens 2, thereby dispersing the fog or melting the ice layer; due to its thickness of only 0.01 mm - 0.05 mm and tight fitting, it can transfer heat efficiently while minimizing the impact on the optical performance of the lens; when the ring heating element 307 also receives the energization instruction, it surrounds the outside of the lens 2 and assists in heating from the edge part, enhancing the overall heating effect and accelerating the de-icing speed.

[0037] Embodiment 1:

[0038] In actual optical device application scenarios, such as in humid areas, the problem of lens fogging seriously affects the normal operation of the device; this embodiment focuses on deeply testing the anti-fogging performance of the transparent graphene heating film 305 in the ice and fog removal mechanism 3 of the present invention in a humid environment; in the ice and fog removal mechanism 3, the limit bracket 301 is tightly clamped inside the lens frame 1, providing a stable support structure for the entire mechanism, and its unique clamping design ensures stable installation in various environments; the lens bracket 302 is firmly installed inside the limit bracket 301 and is closely attached to the right side of the lens 2, not only playing an accurate positioning role for the lens 2, but also providing a stable installation position for the temperature sensor 303 and the humidity sensor 304, enabling the sensors to accurately sense the temperature and humidity changes around the lens 2.

[0039] Experimental preparation: Build an experimental chamber that can simulate a humid environment, fix the optical lens equipped with the ice and fog removal mechanism 3 of the present invention inside the experimental chamber, and ensure that the lens position is stable and does not affect the test results; connect the temperature sensor 303, the humidity sensor 304 and the control module 311 to ensure normal data transmission. At the same time, connect the power supply lines to the transparent graphene heating film 305 and the annular heating element 307, and the annular heating element 307 is not enabled for the time being.

[0040] Experimental process: Set the humidity inside the experimental chamber to 85% RH relative humidity and the temperature to 20 °C, which are typical humid environment conditions that are likely to cause lens fogging; turn on the environmental simulation system of the experimental chamber, and start the test after the environmental parameters are stable; the temperature sensor 303 and the humidity sensor 304 continuously monitor the environmental data around the lens and transmit it to the control module 311; after receiving the data, the control module 311 determines that the humidity reaches the set threshold and the temperature is higher than 0 °C, and sends a power-on instruction to the electrode 306 of the transparent graphene heating film 305; use a high-precision temperature measuring instrument to measure the surface temperature of the lens 2 every 5 seconds; use an optical clarity detection device to observe and record the clarity change of the lens in real time.

[0041] Experimental data:

[0045] Power-on time (seconds) Clarity score 5 3 10 5 15 8 20 10

[0046] As can be seen from the above data, in a humid environment, when the humidity is high and the temperature is above 0°C, the transparent graphene heating film 305 in the present invention can quickly respond to the instructions of the control module 311 and start working; it can increase the surface temperature of the lens 2 in a short time, effectively disperse the fog, and restore the clarity of the lens, demonstrating the high efficiency of the transparent graphene heating film 305 in the defogging function and the reliability of the control module 311 to accurately control the operation of the heating element according to the sensor data.

[0047] Embodiment 2:

[0048] In a cold outdoor environment, such as the polar regions or mountainous areas in winter, lens icing is a common problem that seriously hinders the normal use of optical devices; this embodiment focuses on exploring the performance of the transparent graphene heating film 305 and the annular heating element 307 in the ice and fog removal mechanism 3 to cooperate in deicing in a cold environment; the transparent graphene heating film 305 in the ice and fog removal mechanism 3 is closely attached to the outer surface of the left side of the lens 2 through a special high-temperature and high-transparency adhesive. Its ultra-thin design of 0.01 - 0.05 mm minimizes the impact on the optical performance of the lens while achieving efficient electro-thermal conversion; the annular heating element 307 is precisely clamped in the annular clamping groove outside the lens 2, and its two cable connection terminals on the outside ensure a stable connection to the power supply, providing auxiliary heating for the lens 2 from the edge part.

[0049] Experimental preparation: Prepare a low-temperature test chamber to simulate a cold environment; place the optical lens equipped with the structure of the present invention into the chamber to ensure that all components are properly connected; evenly spray an appropriate amount of water on the lens surface and wait for the water to freeze naturally to form an ice layer with a thickness of about 1 mm.

[0050] Experimental process: Set the temperature of the test chamber to -10°C and start the experiment; the temperature sensor 303 and the humidity sensor 304 transmit the monitored environmental data to the control module 311. After the control module 311 determines that the temperature is below 0°C, it simultaneously sends an energization instruction to the electrode 306 of the transparent graphene heating film 305 and the annular heating element 307; use an infrared thermal imager to observe the temperature distribution on the surface of the lens 2 and record it every 10 seconds; record the process of the ice layer melting through a high-speed camera.

[0051] Experimental data:

[0056] As can be seen from the above data, in a cold environment, when the temperature is below 0°C, the transparent graphene heating film 305 and the annular heating element 307 work together to quickly increase the temperature of the lens 2 and accelerate the melting of the ice layer. The annular heating element 307 surrounds the outside of the lens 2 and assists in heating from the edge part, complementing the transparent graphene heating film 305, enhancing the overall heating effect, effectively realizing the defrosting function of the lens, and further verifying the effectiveness of the present invention in defrosting.

[0057] Embodiment 3:

[0058] Today, with the diversification of optical devices, it is crucial to ensure the long-term stable operation of the heating defrosting and defogging structure on different devices. In this embodiment, the long-term stability and compatibility of the defrosting and defogging mechanism 3 on various optical devices are comprehensively tested. The control module 311 in the defrosting and defogging mechanism 3 is installed on the outer surface of the lens frame 1 and is stably electrically connected to the temperature sensor 303, humidity sensor 304, electrode 306, and annular heating element 307 through carefully arranged circuits. Its built-in intelligent algorithm can quickly and accurately process sensor data and precisely control the working state of the heating element according to preset conditions, ensuring the stable operation of the entire system in various complex environments. The fastening bracket 308 is movably connected to the left side of the lens frame 1 through the insertion column 309, and the limit gasket 310 closely fits the outer surface of the left side of the lens 2, which not only facilitates the installation and disassembly of the mechanism but also further enhances the protection and fixation of the lens 2.

[0059] Experimental preparation: Select multiple optical devices of different brands and models, including security monitoring cameras, vehicle-mounted cameras, and outdoor photography cameras, and install the heating defrosting and defogging structure of the present invention on the lenses of these devices respectively. Arrange the test site at the working site of the device or in a simulated actual use environment to ensure the long-term stable monitoring of the device operation status.

[0060] Experimental process: Put the installed devices into actual use or run in a simulated actual use scenario for a duration of 3 months. During the operation, use the remote data acquisition system to regularly collect the data of the temperature sensor 303 and humidity sensor 304, as well as the control instruction records of the control module 311 for the transparent graphene heating film 305 and the annular heating element 307. At the same time, regularly check the optical performance of the lens, including indicators such as clarity and color restoration, to observe whether it is affected by the heating defrosting and defogging structure.

[0066]

[0067] As can be seen from the above data, during the long-term use of the heating de-icing and defogging structure of the present invention, it can operate stably, and the compatibility between components is good; the temperature sensor 303 and the humidity sensor 304 can continuously and accurately monitor the environmental data, and the control module 311 can reliably control the heating element to work based on these data, and this structure will not have a negative impact on the optical performance of the lens, meeting the requirements of different optical devices for long-term stable use in complex environments, and demonstrating good stability and compatibility.

[0068] In summary, for the heating de-icing and defogging structure and usage method of this optical lens, by adopting the transparent graphene heating film 305 and the annular heating element 307, it avoids the direct contact and potential damage to the lens surface by the traditional mechanical scraping method; when the humidity data reaches or exceeds the set threshold and the temperature is higher than 0°C, the control module 311 sends an energization instruction to the transparent graphene heating film 305, and it quickly generates heat by virtue of its good electro-thermal conversion performance, and evenly transfers the heat to the surface of the lens 2 to disperse the fog without leaving scratches; this non-contact heating and defogging method not only effectively protects the optical performance of the lens, but also improves the reliability and service life of the device.

[0069] Moreover, for the heating de-icing and defogging structure and usage method of this optical lens, in a cold environment, when the temperature is lower than or equal to 0°C, the control module 311 simultaneously activates the transparent graphene heating film 305 and the annular heating element 307; the annular heating element 307 surrounds the outside of the lens 2 and assists in heating from the edge part to enhance the overall heating effect and accelerate the melting of the ice layer; compared with the traditional chemical reagent coating method, this method does not require manual operation and reduces the risk of erosion of the lens coating and material by corrosive chemical substances; in addition, this structure is compact in design and stable in installation, ensuring efficient operation and long-term stability in harsh environments, and solving the many drawbacks of existing de-icing and defogging methods; mechanical scraping, due to direct contact with the lens surface, is extremely prone to generating scratches during repeated scraping, seriously damaging the optical performance of the lens; chemical reagent coating not only requires manual operation and is a cumbersome process, but also some chemical reagents are corrosive, and long-term use will erode the lens coating and even the lens material.
