[0002] Night vision goggles are an observation device that can be used in dark environments. Night vision goggles usually include image processing components, eyepieces, objective lenses and power supply components. The image processing components include a main shell, a main control circuit board, an image sensor and an image display. Through multiple image components and in conjunction with a laser infrared lighting system, photoelectric conversion technology is used for night vision observation and aiming. At present, monocular night vision goggles have the dual functions of night vision and naked vision, and are lighter and smaller in size and lower in cost than binocular night vision goggles. Therefore, they are particularly suitable as head-mounted night vision goggles.

[0003] For example, Chinese patent publication number CN219997421U discloses a new type of low-power laser night vision device, which relates to the technical field of laser night vision device structure, including a night vision device, wherein a connecting plate is symmetrically installed on one side of the night vision device, an elastic belt is installed between the connecting plates, a connecting rod is fixedly installed on the outer wall of the night vision device, a fixing device is movably installed on one side of the connecting rod, a wearing device is installed on one side of the fixing device, and the wearing device includes a front plate, a first elastic strap, a second elastic strap, a groove and a sponge pad. The laser night vision device structure makes it convenient to connect the night vision device with the wearing device through the arrangement of the connecting rod, the fixing device and the wearing device.

At this time, the first permanent magnet block 201 is automatically inserted into the first card slot 104, so that the observation port 11 and the human eye are again pressed and touched, which is convenient for the left eye to observe and use the monocular night vision device 7. Correspondingly, the monocular night vision device 7 is pulled outward, and after the first permanent magnet block 201 is pulled out of the first card slot 104, the monocular night vision device 7 can be moved from the left eye to the right eye through the above structure. During the movement of the monocular night vision device 7, when the sliding rod 101 moves to the middle of the front plate 4, the inclined guide groove 305 on the sliding rod 101 contacts the push rod 306, and the push rod 306 is pushed upward by the inclined guide groove 305, so that the piston plate 308 moves upward in the second cavity 310, and then the air in the second cavity 310 is quickly compressed by the piston plate 308, so that the airflow in the second cavity 310 is transported to the inside of the blowing plate 301 through the air supply pipe 304, and is evenly blown out to the lens of the monocular night vision device 7 through the multiple blowing holes 302 for cleaning.

[0032] Further Figure 7 and Fig. 9 As shown, it is worth explaining in detail that a return spring 311 is arranged inside the second cavity 310 and is located on the side of the piston plate 308 away from the push rod 306. The two ends of the return spring 311 respectively abut against the piston plate 308 and the side surface of the second cavity 310, and the end of the push rod 306 located in the sliding groove 102 is set as an arc surface end 307; when the piston plate 308 moves upward in the second cavity 310, the return spring 311 is compressed. When the sliding rod 101 moves over the push rod 306, the piston plate 308 is pulled downward and reset by the set return spring 311, and the piston plate 308 resets and moves to the bottom of the second cavity 310.

[0033] Further Figure 3 As shown, it is worth explaining in detail that a fixing plate 10 is fixed on the side of the protrusion 309, and the air pipe 304 passes through the fixing plate 10 and is fixed to the fixing plate 10; the stability of the air pipe 304 is improved by setting the fixing plate 10.

[0034] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a ball bearing can be arranged on the side of the sliding rod 101, and the arranged ball bearing can reduce the friction resistance of the sliding rod 101 when sliding in the sliding groove 102, thereby improving the smoothness of the adjustment of the monocular night vision device 7.

[0035] In summary: the mode of switching the left and right eyes of the monocular night vision device 7 is realized by the adjustment component 1, which greatly reduces the coordinated movements of the head and neck. The left and right eyes can be switched by simply moving the monocular night vision device 7, making the adjustment operation more convenient and simple; in the process of the movement and switching of the monocular night vision device 7, a certain moving pushing force is applied to the monocular night vision device 7 through the set adjustment component 2, so that the monocular night vision device 7 can be quickly and automatically moved and switched into place, and the user does not need to manually move the monocular night vision device 7 throughout the whole process, which effectively improves the efficiency of the movement and switching of the monocular night vision device 7 and the labor-saving operation, and realizes the rapid switching of the monocular night vision device 7 between the left and right eyes, which greatly reduces the delay caused by the observation task when the monocular night vision device 7 is switched, and ensures continuous and uninterrupted monitoring of the environment. At the same time, the convenient and fast switching process of the monocular night vision device 7 enables the user to The user can focus more on observing the target, thereby improving the overall task execution efficiency; in the process of the monocular night vision goggles 7 moving to switch the left and right eyes, the movement of the monocular night vision goggles 7 is used to trigger the cleaning lens assembly 3 to work, so that when the monocular night vision goggles 7 moves to the position of the cleaning lens assembly 3, a certain amount of air is compressed and quickly blown out to the lens of the monocular night vision goggles 7 through the cleaning lens assembly 3, thereby automatically blowing and cleaning the lens of the monocular night vision goggles 7, effectively removing dust, water vapor and tiny impurities adhering to the surface of the lens, ensuring that the lens always remains clear, thereby improving the observation quality and accuracy. At the same time, the user does not need to frequently wipe the lens manually, which reduces the frequency of manual wiping and cleaning, and extends the service life of the night vision goggles. In bad weather or complex environments, the lens clarity can be quickly restored, ensuring that the user can continue to obtain high-quality observation vision.
