Technical Field
[0001] This invention relates to the field of laser ranging equipment technology, and in particular to a variable-focus laser ranging countermeasure device. Background Technology
[0002] Laser ranging technology, with its core advantages such as strong directionality, high ranging accuracy, strong anti-interference capability, and long range, has been widely used in military fire control, battlefield reconnaissance, security and control, and industrial surveying, and is one of the core functional modules of modern optoelectronic equipment. Meanwhile, laser optoelectronic countermeasures technology, as a key means of battlefield optoelectronic defense, can actively suppress, deceive, or blind enemy laser rangefinders, optoelectronic guided weapons, and infrared detection equipment by emitting high-repetition-rate jamming pulses and blinding lasers, making it a core component of modern integrated offensive and defensive equipment. To this end, patent CN113466885B discloses a laser ranging sensor distance measurement device. The pre-mounted block has a screw on its end face, and the upper and lower ends of the pre-mounted block have embedding grooves that fit the embedding block. The base has slots on both sides, and the lower end of the slider has buckles on both sides. The buckles are inserted into the slots, and the screw is inserted into the threaded hole at the front end of the sensor housing. This invention, a laser ranging sensor distance measurement device, belongs to the field of laser ranging sensors. The screw is inserted into the threaded hole at the front end of the sensor housing to connect the pre-mounted block and the sensor housing. The pre-mounted block is embedded in the pre-mounted groove, and the upper and lower embedding grooves of the pre-mounted block fit into the upper and lower walls of the pre-mounted groove, allowing the pre-mounted block to be positioned. After the buckles are inserted into the slots, a fixed connection is achieved between the slider and the base, thus enabling rapid assembly of the pre-mounted block, slider, and base, thereby completing the rapid installation between the base and the sensor housing. The existing technical solutions mentioned above have the following drawbacks: when in use, the telescopic light shield cannot be quickly unfolded, resulting in a cumbersome preparation process and low operating efficiency before the equipment is used. Furthermore, stray light will directly enter the receiving optical path, causing a decrease in signal-to-noise ratio, ranging hop count, false distance, and shortened detection distance.

[0007] Preferably, a movable column is fixedly connected to the outer wall of the receiving frame, a sealing movable plug is fixedly connected to one end of the movable column, an air cylinder shell is movably connected to the outer wall of the sealing movable plug, an air supply pipe is installed at the output end of the air cylinder shell, a dust removal nozzle is fixedly connected to one end of the air supply pipe, an air inlet valve is fixedly connected to the outer wall of the air cylinder shell, and an air inlet pipe is installed on the outer wall of the air inlet valve.
[0008] Preferably, the movable column and the air cylinder shell form a sliding structure, and the sealing movable plug and the air cylinder shell form a sliding structure.
[0009] Preferably, the air cylinder shell is fixedly installed on the outer wall of the main body of the zoom laser rangefinder anti-counterfeiting integrated machine, the dust removal nozzle is symmetrically arranged with respect to the central axis of the telescopic light shield, and the dust removal nozzle is inclined.
[0010] Preferably, the bottom of the telescopic light shield is fixedly connected to a rack, the outer wall of the rack is movably connected to a transmission gear, the inner wall of the transmission gear is fixedly connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to a support plate, the outer wall of the support plate is fixedly connected to a protective cover plate, and the outer wall of the zoom laser ranging countermeasurement integrated machine body is fixedly connected to a support frame.
[0011] Preferably, the rack is meshed with the transmission gear, the transmission gear is connected to the support frame via a rotating shaft to form a rotating structure, the support plate is connected to the support frame via a rotating shaft to form a rotating structure, and the protective cover is adapted to the zoom lens and the rangefinder receiving lens respectively.
[0012] Preferably, an L-shaped assembly plate is fixedly connected to the bottom of the main body of the zoom laser ranging countermeasure integrated machine. The L-shaped assembly plate has a positioning hole inside. A fixed base plate is installed at the bottom of the L-shaped assembly plate. A docking plate is fixedly connected to the top of the fixed base plate. A docking groove is opened inside the docking plate. A U-shaped positioning frame is fixedly connected to the top of the docking plate. A limit rod is movably connected inside the U-shaped positioning frame. A spring reset plate is fixedly connected to the outer wall of the limit rod.
[0013] Preferably, the limiting rod and the U-shaped positioning frame form a sliding structure, the docking plate is engaged with the L-shaped assembly plate through the docking groove, the docking plate is symmetrically arranged about the central axis of the fixed base plate, and the limiting rod is engaged with the L-shaped assembly plate through the positioning hole.
[0014] The present invention provides a variable-focus laser ranging and countermeasure integrated device, the advantages of which are: Equipped with a zoom lens, a range-measuring receiving lens, and an adjustment mechanism, the drive motor can rotate the threaded rod, causing the movable block to slide and the receiving frame to slide along the guide groove. This allows the telescopic light shield to be stretched out, providing light protection for the zoom lens and the range-measuring receiving lens, preventing stray light from directly entering the receiving optical path, improving the accuracy of laser ranging, shortening the preparation time before ranging, and increasing ranging efficiency. Furthermore, the guiding action of the guide plate can improve the stability of the sliding of the movable block, further improve the stability of the stretchable sunshade, and improve the efficiency of the distance measurement operation. Furthermore, as the receiving frame moves, it drives the movable column to move, causing the sealing movable plug to slide along the outer shell of the air cylinder. Compressed air is then delivered to the dust removal nozzle through the air supply pipe. Simultaneously, the dust removal nozzle moves synchronously with the telescopic light shield while blowing air, thus achieving the effect of cleaning the zoom lens and range-measuring receiving lens by blowing dust while the telescopic light shield is unfolded. This avoids the need to clean the zoom lens and range-measuring receiving lens separately before use, further shortening the preparation time before ranging and improving ranging efficiency. Furthermore, as the telescopic lens hood moves, the rack moves synchronously, causing the transmission gear to rotate accordingly. This causes the two protective covers to flip open along the zoom lens and the rangefinder receiving lens, respectively. This achieves the effect of flipping open the protective covers while the telescopic lens hood extends and retracts, further improving the ranging efficiency. At the same time, when the telescopic lens hood retracts, it will cause the protective covers to automatically flip and close, thus protecting the zoom lens and the rangefinder receiving lens. The system includes a main body for a zoom laser ranging countermeasurement device, L-shaped assembly plates, positioning holes, docking plates, docking slots, a U-shaped positioning frame, limit rods, and a spring reset plate. By pulling the limit rod upwards, it slides along the U-shaped positioning frame, compressing the spring reset plate. At this time, the main body of the zoom laser ranging countermeasurement device is moved, allowing the two L-shaped assembly plates to slide into the docking slots inside the docking plate. Releasing the limit rod allows its end to be inserted into the positioning hole for positioning, facilitating quick assembly of the main body of the zoom laser ranging countermeasurement device.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-10 The present invention provides a variable-focus laser ranging countermeasure integrated device, including a variable-focus laser ranging countermeasure integrated machine body 1.
[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, a zoom lens 2 is installed on one side of the main body 1 of the zoom laser ranging countermeasure integrated machine, and a ranging receiving lens 3 is installed on the other side of the main body 1. An adjustment mechanism 4 is installed on the top of the main body 1. The adjustment mechanism 4 includes a control box 41 fixedly installed on the top of the main body 1. A guide groove 42 is opened inside the control box 41. A drive motor 43 is fixedly connected inside the control box 41. The output shaft of the drive motor 43 is fixedly connected to a threaded rod 44 through a coupling. A guide plate 45 is fixedly connected to the inner wall of the control box 41. The outer wall of the threaded rod 44 is movable. A movable block 46 is connected to the movable block 46. The movable block 46 has a threaded groove 47 inside. A receiving frame 48 is fixedly connected to the top of the movable block 46. A telescopic light shield 49 is fixedly connected to the outer wall of the receiving frame 48. The telescopic part of the telescopic light shield 49 is fixedly installed on one side of the telescopic part of the telescopic light shield 49 to the outer wall of the main body 1 of the zoom laser rangefinder anti-counterfeiting integrated machine. The threaded rod 44 and the control box 41 form a rotating structure. The threaded rod 44 is threadedly connected to the movable block 46 through the threaded groove 47. The movable block 46 has a slotted design. The movable block 46 and the control box 41 form a sliding structure through the guide plate 45. The receiving frame 48 and the control box 41 form a sliding structure through the guide groove 42.
[0020] By starting the drive motor 43, the threaded rod 44 can be rotated. Since the threaded rod 44 is threadedly connected to the movable block 46 through the threaded groove 47, the movable block 46 can slide along the guide plate 45, causing the receiving frame 48 to slide along the guide groove 42 opened inside the control box 41, so that the telescopic light shield 49 is stretched and unfolded, causing the telescopic light shield 49 to provide light protection for the zoom lens 2 and the ranging receiving lens 3. By starting the dual-wavelength laser in the main body 1 of the zoom laser ranging and anti-counterfeiting integrated machine, the zoom lens 2 emits laser, and the ranging receiving lens 3 receives the laser signal, thereby realizing zoom laser ranging.
[0021] Reference Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, a movable column 481 is fixedly connected to the outer wall of the receiving frame 48. A sealing movable plug 482 is fixedly connected to one end of the movable column 481. An air cylinder shell 483 is movably connected to the outer wall of the sealing movable plug 482. An air supply pipe 484 is installed at the output end of the air cylinder shell 483. A dust removal nozzle 485 is fixedly connected to one end of the air supply pipe 484. An air inlet valve 486 is fixedly connected to the outer wall of the air cylinder shell 483. An air inlet pipe 487 is installed on the outer wall of the air inlet valve 486. The movable column 481 and the air cylinder shell 483 form a sliding structure, as do the sealing movable plug 482 and the air cylinder shell 483. The air cylinder shell 483 is fixedly installed on the outer wall of the main body 1 of the zoom laser ranging and countermeasure integrated machine. The dust removal nozzles 485 are symmetrically arranged along the central axis of the telescopic light shield 49. 5 is inclined. The bottom of the telescopic light shield 49 is fixedly connected to a rack 491. The outer wall of the rack 491 is movably connected to a transmission gear 492. The inner wall of the transmission gear 492 is fixedly connected to a rotating shaft 493. The outer wall of the rotating shaft 493 is fixedly connected to a support plate 494. The outer wall of the support plate 494 is fixedly connected to a protective cover plate 495. The outer wall of the main body 1 of the zoom laser rangefinder countermeasure integrated machine is fixedly connected to a support frame 5. The rack 491 and the transmission gear 492 are meshed and connected. The transmission gear 492 and the support frame 5 form a rotating structure through the rotating shaft 493. The support plate 494 and the support frame 5 form a rotating structure through the rotating shaft 493. The protective cover plate 495 is adapted to the zoom lens 2 and the rangefinder receiving lens 3 respectively, and the protective cover plate 495 is symmetrically arranged with respect to the central axis of the support plate 494.
[0022] As the receiving frame 48 moves, it drives the movable column 481 to move, causing the sealing movable plug 482 to slide along the air cylinder shell 483, thus compressing the air inside the air cylinder shell 483. At this time, the air inlet valve 486 is closed, and the compressed air is delivered to the dust removal nozzle 485 through the air delivery pipe 484 for discharge. Simultaneously, the dust removal nozzle 485 moves synchronously with the telescopic light shield 49 while blowing air, thereby enabling the dust removal nozzle 485 to spray air onto the zoom lens 2 and the rangefinder receiving lens 3 while the telescopic light shield 49 is unfolding. When the telescopic sunshade 49 retracts and resets, the air inlet valve 486 opens, allowing outside air to enter the air cylinder housing 483 through the air inlet pipe 487. As the telescopic sunshade 49 moves, the rack 491 moves synchronously. Since the rack 491 is meshed with the transmission gear 492, the transmission gear 492 can rotate accordingly, causing the support plate 494 fixedly connected to the outer wall of the rotating shaft 493 to rotate along the support frame 5, so that the two protective covers 495 flip open along the zoom lens 2 and the rangefinder receiving lens 3 respectively.
[0023] Reference Figure 8 , Figure 9 and Figure 10 As shown, an L-shaped assembly plate 6 is fixedly connected to the bottom of the main body 1 of the zoom laser ranging countermeasure integrated machine. The L-shaped assembly plate 6 has a positioning hole 7 inside. A fixed base plate 8 is installed at the bottom of the L-shaped assembly plate 6. A docking plate 9 is fixedly connected to the top of the fixed base plate 8. A docking groove 10 is opened inside the docking plate 9. A U-shaped positioning frame 11 is fixedly connected to the top of the docking plate 9. A limit rod 12 is movably connected inside the U-shaped positioning frame 11. A spring reset plate 13 is fixedly connected to the outer wall of the limit rod 12. The limit rod 12 and the U-shaped positioning frame 11 form a sliding structure. The docking plate 9 is engaged with the L-shaped assembly plate 6 through the docking groove 10. The docking plate 9 is symmetrically arranged about the central axis of the fixed base plate 8. The limit rod 12 is engaged with the L-shaped assembly plate 6 through the positioning hole 7.
[0024] By pulling the limiting rod 12 upward, it slides along the U-shaped positioning frame 11, causing the spring reset plate 13 to be compressed. At this time, the main body 1 of the zoom laser ranging countermeasurement machine is moved, so that the two L-shaped assembly plates 6 slide into the docking grooves 10 opened inside the docking plate 9 respectively. When the L-shaped assembly plates 6 are fully inserted into the docking grooves 10, the limiting rod 12 is released. Under the action of the spring reset plate 13, the limiting rod 12 can slide back along the U-shaped positioning frame 11 and the end of the limiting rod 12 is inserted into the positioning hole 7 for limiting, so that the main body 1 of the zoom laser ranging countermeasurement machine can be quickly assembled.
