Description
Technical Field

[0002] In today's era of rapid technological development, infrared technology is widely used in military reconnaissance, civil security, industrial detection and other fields, and its importance is self-evident. Faced with diverse application scenarios and harsh environmental challenges, the performance requirements of infrared lenses continue to rise. Especially in military conflicts, industrial construction and harsh natural environments, lenses need to withstand tests such as explosion shocks, mechanical collisions and accidental falls. Therefore, modern infrared lenses not only need excellent optical performance, but also need to show strong impact resistance and stability to ensure stable operation under complex and changing conditions, fully unleash the ultimate performance of infrared detectors, protect safety, and gain insight into the future. The external lens of the existing technology has significant defects in complex environments: first, impact and vibration can easily cause tiny displacement of the optical elements inside the lens, directly affecting the focusing accuracy, making the captured image blurred, and greatly reducing the image quality and usability; second, in the face of strong impact and vibration, the optical elements may be deformed, broken or dislocated, seriously damaging the integrity of the optical system, and then causing a series of optical performance degradation problems such as sharp resolution reduction, color deviation, and contrast loss; third, the mechanical structure is also vulnerable to the damage, and the frequent failures such as lens barrel deformation, loose screws, and broken connectors seriously threaten the stability and reliability of the lens. In extreme cases, it is more likely to cause the lens to completely fail and unable to perform shooting tasks. Therefore, improving the impact and vibration resistance of the external lens has become a technical problem that needs to be solved urgently. Utility Model Content

Specific embodiments
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] As Figures 1 to 5 shown, the present utility model provides an impact-resistant electric focusing infrared lens, including the first gear 1. A bearing seat 2 is fixedly installed at the top of the first gear 1. A bearing 3 is movably installed on the outer surface of the bearing seat 2. A lens barrel 4 is fixedly installed on the outer surface of the bearing seat 2. A first lens 9 is fixedly installed inside the lens barrel 4, and a first retaining ring 8 is fixedly installed on the outer surface of the first lens 9. A second lens 11 is movably installed inside the lens barrel 4, and a second retaining ring 10 is fixedly installed on the outer surface of the second lens 11. A focusing frame 12 is fixedly installed inside the bearing 3. A third lens 14 is movably installed inside the focusing frame 12, and a third retaining ring 13 is fixedly installed on the outer surface of the third lens 14. A fourth lens 25 is fixedly installed on the back of the lens barrel 4, and a fifth retaining ring 24 is fixedly installed on the outer surface of the fourth lens 25.
[0021] When starting the focusing process, the staff turns on the drive motor 19, which starts rotating as the power core. The power is transmitted through the precision gear transmission system to gear two 5, and then drives the focusing cam 22 to rotate. The unique design of the focusing cam 22 ingeniously converts the rotational motion into a linear motion, pushing or pulling the third lens 14 in the focusing lens frame 12 to slide smoothly in the lens barrel 4, achieving fine adjustment of the focal length. During the focusing process, the contact between the cam groove and the guide post 7 serves as a mechanical limit to ensure that the third lens 14 can accurately reach the preset limit position. At the same time, the limit post 23 touches the tab of the limit switch 20, converting the mechanical signal into an electrical signal to immediately control the motor 19 to stop, ensuring that the focusing process is both accurate and safe. In addition, the potentiometer 18 integrated in the system is connected to the transmission system through gear one 1, real-time records the rotational position of the cam, converts it into a resistance change, provides immediate feedback on the focusing status to the operator, and lays a solid foundation for subsequent automated focusing or precise reset operations.
[0022] The drive motor 19 is turned on and starts rotating, driving gear two 5 and the focusing cam 22 to rotate through the precision gear transmission system. The unique design of the focusing cam 22 converts the rotational motion into a linear motion, pushing the third lens 14 to slide smoothly in the lens barrel to achieve fine adjustment of the focal length. The cam groove and the guide post 7 ensure that the lens can accurately reach the preset position. The limit post 23 touches the limit switch to stop the motor, ensuring accurate and safe focusing. At the same time, the potentiometer 18 is connected to the transmission system through gear one 1, real-time records the rotational position of the cam and converts it into a resistance change, providing immediate feedback to the operator. Compared with traditional infrared lenses, this infrared lens can effectively resist accidental impacts and vibrations, ensure the integrity and stability of the structure, significantly extend the lens life, and reduce the maintenance cost caused by external damage. Whether facing the complex and changeable industrial site or the harsh outdoor environment, this lens can operate stably, provide a solid guarantee for the infrared imaging system, and significantly improve its durability and reliability. And the retaining rings one 8, two 10, three 13, four 16 and five 24 are made of aluminum alloy material, and all the retaining rings are pasted inside the lens barrel 4 with silicone rubber.
[0023] One end of gear one 1 is fixedly installed with a motor base 6. The bottom of the motor base 6 is fixedly installed with a potentiometer 18. There is a switch base one 17 fixedly installed between the potentiometer 18 and the lens barrel 4, and the switch base one 17 presents an arc shape. The bottom of the motor base 6 is fixedly installed with a motor 19, and the top of the motor base 6 is fixedly installed with gear two 5.
[0024] Through the buffering technology of bearing 3 and the adjustment technology of potentiometer 18, the bearing seat 2 is firmly installed on the outer edge of the lens barrel. The built-in bearing serves as the core of impact buffering. The rotating rod of the potentiometer 18 is tightly fixed in the first gear 1 and the bearing 3 through silicone rubber to achieve precise transmission. External impacts are first received by the bearing seat 2, and the impact energy is effectively absorbed and dispersed through the rotation mechanism of the bearing 3, greatly reducing the impact force transmitted to the potentiometer and ensuring the stable operation of the potentiometer in a complex environment. The internal sliding element can smoothly slide to adjust the resistance, achieving precise output control and being protected from impact damage at the same time. Compared with traditional infrared lenses, this infrared lens in an impact-resistant motorized focusing lens ensures the stability of optical components without displacement, guarantees clear and precise imaging. Its motorized focusing function can flexibly meet various shooting requirements, accurately locate the focal length, and capture clear targets. In emergency situations such as earthquakes and fires, the lens still works stably, providing key images for rescue and monitoring. The motorized focusing is convenient and efficient, adapting to objects at different distances without manual operation, improving the operation efficiency and safety.
[0025] Among them, a limit switch 20 and a second switch seat 21 are fixedly installed on the outer surface of the lens barrel 4, and the second switch seat 21 is inside the limit switch 20. A limit post 23 is threadedly sleeved inside the limit switch 20 and the second switch seat 21.
[0026] Among them, a guide post 7 is fixedly and movably installed inside the lens barrel 4, a fourth retaining ring 16 is movably installed inside the lens barrel 4, a washer 15 is fixedly installed inside the fourth retaining ring 16, and the washer 15 is made of rubber material. A focusing cam 22 is fixedly installed inside the lens barrel 4.
[0027] Among them, a threaded hole 26 is formed inside the lens barrel 4, and the threaded holes 26 are arranged in a circumferential array.
[0028] Since the threaded holes 26 are arranged in a circumferential array and abut against the inside of the lens barrel 4, it is convenient to fix the lens barrel 4 inside the housing, improving the stability of the lens barrel 4 during use and enhancing the service efficiency of the lens barrel 4.
[0029] The working principle and usage process of the present utility model:
[0030] The staff activates the drive motor 19, which rotates as the power core. The power is transmitted to gear two 5 through the precision gear transmission system, driving the focusing cam 22 to rotate. Due to the ingenious design of the focusing cam 22, the rotational motion is converted into linear motion, pushing lens three 14 to slide smoothly within the lens barrel to achieve fine adjustment of the focal length. During the focusing process, the cam groove contacts the guide post 7 to ensure that the lens accurately reaches the preset position. The limit post 23 touches the limit switch 20, converting the mechanical signal into an electrical signal to immediately stop the motor, ensuring precise and safe focusing. Meanwhile, the potentiometer 18 is connected to the transmission system through gear one 1, recording the position of the cam in real time and converting it into a resistance change, providing immediate feedback to the operator and laying a solid foundation for subsequent automated focusing or precise reset operations, ensuring the stability and reliability of the entire focusing process.
