[0033] Such as Figures 1-9As shown in the figure, an intelligent zoom infrared monitoring and display device includes an infrared imager body 1. One side of the rear end of the infrared imager body 1 is fixedly installed with a connecting part 2. An imaging lens 3 is arranged at the rear end of the connecting part 2. The imaging lens 3 is composed of an upper housing 31 and a lower housing 32. A connecting sleeve 4 is commonly connected between the imaging lens 3 and the connecting part 2. An automatic focusing component 6 and an objective lens 7 are arranged inside the imaging lens 3. A manual focusing component 5 is arranged on the upper part of the outer surface of the upper housing 31.

[0034] Specifically, please refer to Figures 3-4 , a first fixing groove 311 is arranged at the rear part of the inner cavity of the upper housing 31. Upper fixing pieces 312 are symmetrically and fixedly installed at the edge of the outer surface of the upper housing 31. An upper sliding groove 313 is opened at the edge of the inner wall of the upper housing 31. A first upper wire passing hole 314 is opened in the middle of one side of the upper housing 31 close to the connecting part 2.

[0035] The lower housing 32 includes a lower fixing sleeve 321 and a connecting cylinder 322. A second fixing groove 324 is arranged at the position corresponding to the first fixing groove 311 at the rear part of the lower fixing sleeve 321. Lower fixing pieces 325 are symmetrically and fixedly installed at the edge of the outer surface of the lower fixing sleeve 321. Semi-circular grooves 328 are opened on the inner walls of the lower fixing sleeve 321 and the inner wall of the upper housing 31 on the side close to the connecting part 2. The connecting cylinder 322 and the lower fixing sleeve 321 are of an integrally formed structure, and two limiting grooves 323 are opened on the outer surface of the connecting cylinder 322. A second upper wire passing hole 326 is opened at the upper part of the connecting cylinder 322. A lower wire passing hole 329 communicating with the inner cavity of the lower fixing sleeve 321 is commonly opened between the connecting cylinder 322 and the lower part of the lower fixing sleeve 321. Lower sliding grooves 327 are symmetrically opened on the inner wall of the lower fixing sleeve 321 for facilitating wire passing.

[0036] It should be noted that the first fixing groove 311 and the second fixing groove 324 together form a complete installation groove, and the objective lens 7 is embedded in the installation groove. In addition, in this embodiment, by providing the upper fixing pieces 312 and the lower fixing pieces 325, the upper housing 31 and the lower housing 32 can be closed and installed by using screws, thereby forming a complete imaging lens 3.

[0037] Please refer to Figures 5-6, the autofocus assembly 6 includes a fixed ring 61, a ring rack 62 and a servo motor 63. On the left and right outer surfaces of the fixed ring 61, two limit plates 67 are symmetrically and fixedly installed. On the upper and lower outer surfaces of the fixed ring 61, two fixed plates 68 are symmetrically and fixedly installed. There are two servo motors 63, which are respectively symmetrically and fixedly installed on the inner walls of the upper housing 31 and the lower housing 32. The output ends of the two servo motors 63 are fixedly installed with rotating shafts 65 through couplings. On the outer surfaces of the rotating shafts 65 near the servo motors 63, second gears 64 are fixedly installed. On the inner and outer surfaces of the ring rack 62, engaging teeth are provided. The two second gears 64 are both located inside the ring rack 62 and mesh with the engaging teeth on the inner wall of the ring rack 62. On the outer surfaces of the rotating shafts 65 far from the servo motors 63, second external threads 66 are engraved. The ring rack 62 is threadedly connected to the two rotating shafts 65 through the second external threads 66 and the fixed plates 68.

[0038] It should be noted that a focusing lens is fixedly installed in the middle of the fixed ring 61, and the focusing lens is parallel to the objective lens 7 for easy focusing. During actual operation, taking clockwise rotation as an example, by starting the servo motor 63, the servo motor 63 can drive the rotating shaft 65 to rotate clockwise, and then drive the two second gears 64 to rotate clockwise. The four limit plates 67 are respectively slidably connected in the two upper sliding grooves 313 and the two lower sliding grooves 327 to slidably connect the fixed ring 61 with the upper housing 31 and the lower housing 32. The screw principle can be used to move the fixed ring 61 to achieve the purpose of adjusting the focal length. This is the autofocus process.

[0039] Please refer to Figures 3-7 , the manual focus assembly 5 includes a mounting box 51. The mounting box 51 is fixedly installed on the upper outer surface of the upper housing 31 and is in communication with the inner cavity of the upper housing 31. The inner wall of the mounting box 51 is rotatably connected with a central shaft rod 52 through a bearing. In the middle of the outer surface of the shaft rod 52, a first gear 53 is fixedly installed. The lower part of the first gear 53 extends into the inner cavity of the upper housing 31 and meshes with the engaging teeth on the outer surface of the ring rack 62. One end of the shaft rod 52 penetrates through the mounting box 51 and extends to its outside and is fixedly installed with a regulating valve 54.

[0040] It should be noted that during the manual focusing process, by rotating the regulating valve 54, the first gear 53 rotates. Taking clockwise rotation as an example, when the first gear 53 rotates clockwise, since the semi-circular grooves 328 on the inner wall of the lower fixing sleeve 321 and the inner wall of the upper housing 31 form a complete circular sliding groove, the annular rack 62 is slidably connected in the circular sliding groove, and the contact surfaces between the annular rack 62 and the circular sliding groove are filled with lubricating oil. Moreover, the lower part of the first gear 53 extends into the inner cavity of the upper housing 31 and meshes with the teeth on the outer surface of the annular rack 62, so that the annular rack 62 can be rotated counterclockwise. When the annular rack 62 rotates counterclockwise, since the two second gears 64 are both located inside the annular rack 62 and mesh with the teeth on the inner wall of the annular rack 62, the two second gears 64 can be rotated counterclockwise, and then the two rotating shafts 65 are rotated counterclockwise. And the four limiting plates 67 are respectively slidably connected in the two upper sliding grooves 313 and the two lower sliding grooves 327 to slidably connect the fixing ring 61 with the upper housing 31 and the lower housing 32 together. By using the screw principle, the fixing ring 61 can be moved to achieve the purpose of adjusting the focal length. This is the manual focusing process.

[0041] As can be seen from the above manual focusing process, during the manual focusing process, the two servo motors 63 need to be powered off to ensure that the rotation of the rotating shaft 65 has no impact on the servo motors 63. Through the cooperation of manual focusing and automatic focusing, the diversification of the focusing operation is improved. At the same time, after automatic focusing, manual focusing operation can be used again to ensure more accurate focusing.

[0042] Please refer to Figures 2-5 and Figures 7-9 , at one end of the connecting part 2 far away from the infrared imager body 1, two electrode plates 22 are symmetrically and fixedly installed. The two electrode plates 22 are respectively an anode plate and a cathode plate. At one end of the connecting cylinder 322 close to the connecting part 2, two rectangular grooves 9 are symmetrically opened, and the two rectangular grooves 9 correspond to the positions of the two electrode plates 22 one by one. A plurality of buffer springs 10 are fixedly installed on the inner walls of the two rectangular grooves 9. One ends of the plurality of buffer springs 10 far away from the inner walls of the rectangular grooves 9 are fixedly installed with metal plates 8; when the plurality of buffer springs 10 are all in the natural state, one end of the metal plate 8 far away from the buffer spring 10 extends outside the rectangular groove 9; the two rectangular grooves 9 are respectively communicated with the second upper wire hole 326 and the lower wire hole 329, and the second upper wire hole 326 is communicated with the inner cavity of the upper housing 31 through the first upper wire hole 314.

[0043] It can be seen that by providing two electrode plates 22, with the two electrode plates 22 being the anode plate and the cathode plate respectively, when the imaging lens 3 is docked with the connecting portion 2, since when a plurality of buffer springs 10 are all in the natural state, the end of the metal plate 8 away from the buffer spring 10 extends outside the rectangular groove 9, the two metal plates 8 can be made to closely adhere to the two electrode plates 22 respectively, so as to realize the power supply to the two servo motors 63. This is a wireless electrical contact method, which is conducive to the disassembly of the imaging lens 3. When the components in the imaging lens 3 are damaged, it is convenient to replace or repair them.

[0044] In addition, in the present invention, anti-slip ridges 41 are provided on the outer surface of the connecting sleeve 4. Two limiting rings 43 are fixedly installed at the rear part of the inner wall of the connecting sleeve 4, and the two limiting rings 43 and the connecting sleeve 4 are of an integrally formed structure. Internal threads 42 are engraved on the front part of the inner wall of the connecting sleeve 4. The two limiting rings 43 are respectively slidably connected in the two limiting grooves 323 to rotatably connect the connecting sleeve 4 with the lower housing 32. An external thread 21 is engraved on one side of the outer surface of the connecting portion 2 away from the infrared imager body 1. The connecting sleeve 4 is threadedly connected with the connecting portion 2 through the internal threads 42 and the external thread 21, thereby completing the connection of the imaging lens 3 and the connecting portion 2, and the operation is simple and convenient, and it is convenient to disassemble later.

[0045] It should be noted that in the present invention, the joints between the upper housing 31 and the lower housing 32 are sealed with sealing strips to prevent external light from entering the inner cavities of the upper housing 31 and the lower housing 32 through the joints between the upper housing 31 and the lower housing 32 and thus affecting the infrared imaging effect.

[0046] In summary, the present invention provides an automatic focusing component 6 and a manual focusing component 5, which improves the diversification of the focusing operation. At the same time, after automatic focusing, the manual focusing operation can be used again to ensure more accurate focusing. In the present invention, the imaging lens 3 is composed of an upper housing 31 and a lower housing 32, and it can be disassembled. When the components in the imaging lens 3 are damaged, it is convenient to replace or repair them.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
