[0001] The present invention relates to the technical field of night vision devices, and more particularly to a monocular head-mounted night vision device. Background Art

[0002] A night vision device is an observation device that can be used in a dark environment. A night vision device generally includes an image processing component, an eyepiece, an objective lens, and a power supply component. The image processing component includes a main housing, a main control circuit board, an image sensor, and an image display. Through multiple image components and in cooperation with a laser infrared illumination system, using optoelectronic conversion technology, it is used for night vision observation and telescopic sight aiming; currently, a monocular night vision goggle has the dual functions of night vision and naked vision, and compared with a binocular night vision goggle, it has a smaller weight and volume and a lower cost. Therefore, it is particularly suitable as a head-mounted night vision goggle.

[0003] As disclosed in Chinese Patent Publication No. CN219997421U, a novel low-power laser night vision device is disclosed, which relates to the technical field of laser night vision device structures. It includes a night vision device. Elastic bands are installed between the connecting plates symmetrically installed on one side of the night vision device. 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. The wearing device includes a front plate, a first elastic strap, a second elastic strap, a groove, and a sponge pad. In this laser night vision device structure, through the settings of the connecting rod, the fixing device, and the wearing device, the night vision device is conveniently connected to the wearing device. At the same time, the setting of the wearing device enables the night vision device to be worn on the head, freeing the hands and enabling the hands to be useful, solving the drawbacks of existing night vision devices and greatly improving the practicality of the night vision device.

[0004] As disclosed in Chinese Patent Publication No. CN220511175U, a head-mounted monocular night vision device is disclosed, which relates to the technical field of monocular night vision devices.

[0021] 3. During the process of switching between the left and right eyes by moving a monocular night vision device, the movement of the monocular night vision device is utilized to trigger the lens cleaning component to operate.

At the same time, users do not need to frequently wipe the lens manually, reducing the frequency of manual wiping and cleaning, extending the service life of the night vision goggles.

[0037] The present invention will be further described below in conjunction with embodiments.

[0038] Please refer to Figure 1-12, the present invention provides a monocular head-mounted night vision device, which includes a connecting block 5. A headband assembly 6 is installed on the connecting block 5. The headband assembly 6 includes a first elastic bandage 601 and a second elastic bandage 602. The two ends of the first elastic bandage 601 are respectively fixed to the two opposite side surfaces of the connecting block 5. The two ends of the second elastic bandage 602 are respectively fixed to the side surface of the connecting block 5 and the first elastic bandage 601. A connecting frame 8 is fixed on the side surface of the connecting block 5. One end of the connecting frame 8 away from the connecting block 5 is fixed with a front plate 4 located below the connecting block 5. A monocular night vision device 7 is arranged below the front plate 4. A switching and adjusting component 1 for driving the monocular night vision device 7 to slide and move on the front plate 4 is arranged on the front plate 4. An additional adjusting component 2 for cooperating with the switching and adjusting component 1 to enable the monocular night vision device 7 to be quickly adjusted is arranged at the end of the front plate 4. A lens cleaning component 3 for cooperating with the switching and adjusting component 1 to clean the lens of the monocular night vision device 7 is arranged at the middle of the front plate 4; when in use, the user can wear the first elastic bandage 601 and the second elastic bandage 602 on the head, so as to wear the monocular night vision device 7 on the head for use, freeing both hands. By setting the switching and adjusting component 1, the monocular night vision device 7 can be moved, switched and adjusted to different ends of the front plate 4, thus realizing the conversion of the monocular night vision device 7 between the left and right eye positions. It allows the user to conveniently move the monocular night vision device 7 from one eye to the other after long-term monocular observation, effectively relieving the visual fatigue caused by long-term monocular use, helping to maintain the user's alertness and observation efficiency, enabling the user to easily switch the observation eye according to personal habits, greatly improving the flexibility of use. At the same time, the method of realizing the movement, switching between the left and right eyes of the monocular night vision device 7 through the switching and adjusting component 1 greatly reduces the coordinated movements of the head and neck. Only by simply moving the monocular night vision device 7 can the switching between the left and right eyes be realized, making the adjustment operation more convenient and simple;

[0039] During the process of the monocular night vision device 7 moving and switching, a certain moving pushing force is applied to the monocular night vision device 7 through the set increasing adjustment component 2, enabling the monocular night vision device 7 to quickly and automatically move and switch into place. The user does not need to manually move the monocular night vision device 7 throughout the process, effectively improving the efficiency and labor-saving nature of the movement and switching of the monocular night vision device 7, achieving a rapid switch of the monocular night vision device 7 between the left and right eyes, greatly reducing the delay caused to the observation task during the switching of the monocular night vision device 7, ensuring continuous and uninterrupted monitoring of the environment. At the same time, the convenient and rapid switching process of the monocular night vision device 7 enables the user to focus more on the observation target, improving the overall task execution efficiency; during the process of the monocular night vision device 7 moving and switching between the left and right eyes, the cleaning mirror component 3 is triggered to work by using the movement of the monocular night vision device 7. Thus, when the monocular night vision device 7 moves to the position of the cleaning mirror component 3, a certain amount of air is compressed and quickly blown onto the lens of the monocular night vision device 7 through the cleaning mirror component 3, thereby automatically blowing and cleaning the lens of the monocular night vision device 7, effectively removing dust, water vapor, and tiny impurities adhering to the lens surface, ensuring that the lens always remains clear, further improving the observation quality and accuracy. At the same time, the user does not need to frequently wipe the lens manually, reducing the frequency of manual wiping and cleaning, extending the service life of the night vision goggles, and being able to quickly restore the lens clarity in bad weather or complex environments, ensuring that the user can continuously obtain a high-quality observation field of view.

[0040] Furthermore, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, it is worth specifically explaining that the tone-changing component 1 includes a sliding groove 102 opened on the side surface of the front plate 4. The sliding groove 102 is arranged along the length direction of the front plate 4. A sliding rod 101 is slidably connected in the sliding groove 102. The cross-section of the sliding rod 101 is rectangular. The monocular night vision device 7 is fixed to one end of the sliding rod 101 away from the connecting block 5 and the monocular night vision device 7 is arranged below the front plate 4. A limiting plate 103 is fixed to one end of the sliding rod 101 close to the connecting block 5. The sliding rod 101 can slide in the sliding groove 102. By providing the limiting plate 103, the sliding rod 101 is prevented from sliding out of the sliding groove 102. The monocular night vision device 7 is driven by the sliding rod 101 to move synchronously. Thus, through the cooperation of the sliding rod 101 and the sliding groove 102, the monocular night vision device 7 can be moved and adjusted to different ends of the front plate 4, thereby realizing the conversion of the monocular night vision device 7 between the left and right eye positions. It allows the user to conveniently move the monocular night vision device 7 from one eye to the other after observing with one eye for a long time, effectively relieving the visual fatigue caused by long-term use of one eye, helping to maintain the user's alertness and observation efficiency, enabling the user to easily switch the observing eye according to personal habits, greatly improving the flexibility of use. At the same time, by using the tone-changing component 1 to realize the movement and switching of the monocular night vision device 7 between the left and right eyes, the coordinated movements of the head and neck are greatly reduced. Only by simply moving the monocular night vision device 7 can the left and right eyes be switched, making the adjustment operation more convenient and simple.

[0041] Further, as Figure 1 、 Figure 2 、 Figure 3 and Figure 10As shown, it is worth specifically explaining that the boosting component 2 includes two convex plates 204 fixed at both ends of the front plate 4. Electromagnet blocks 202 are fixed on the opposite side surfaces of the two convex plates 204. A first permanent magnet block 201 that cooperates with the electromagnet block 202 is fixed on the side surface of the sliding rod 101. A small current controller 203 electrically connected to the electromagnet block 202 is fixed on the outer side surface of the convex plate 204. A control button is installed on the small current controller 203. The specific model of the small current controller 203 can be MHVD0-6 type-1X08. A mobile battery is installed on the monocular night vision device 7. The small current controller 203 is electrically connected to the mobile battery on the monocular night vision device 7. An observation port 11 is provided at one end of the monocular night vision device 7 away from its lens. During use, the small current controller 203 inputs current into the electromagnet block 202, making the electromagnet block 202 magnetic. At this time, the poles of the electromagnet block 202 and the first permanent magnet block 201 at the end of the convex plate 204 close to the sliding rod 101 that are close to each other are opposite. Thus, the sliding rod 101 and the monocular night vision device 7 are fixed and positioned through the attraction of the first permanent magnet block 201 and the electromagnet block 202, enabling the monocular night vision device 7 to be stably used. When the monocular night vision device 7 needs to be moved to switch between the left and right eyes, by pressing the switches on the two small current controllers 203, the small current controller 203 controls the input of reverse current into the electromagnet block 202. At this time, the poles of the electromagnet block 202 and the first permanent magnet block 201 at the end of the convex plate 204 close to the sliding rod 101 that are close to each other are the same. Thus, a certain moving pushing force is applied to the monocular night vision device 7 through the repulsive force between the electromagnet block 202 and the first permanent magnet block 201, pushing the sliding rod 101 and the monocular night vision device 7 to move towards the other end of the front plate 4. At this time, the poles of the electromagnet block 202 and the first permanent magnet block 201 at the convex plate 204 at the other end of the front plate 4 that are close to each other are opposite, so they attract each other, and the first permanent magnet block 201 on the sliding rod 101 is adsorbed onto the electromagnet block 202 at the other end of the front plate 4, enabling the monocular night vision device 7 to quickly and automatically move and switch to the other end of the front plate 4, that is, quickly switch the monocular night vision device 7 to the other eye for observation. The user does not need to manually move the monocular night vision device 7 throughout the process, effectively improving the efficiency of moving and switching the monocular night vision device 7 and the labor-saving nature of the operation. Repeating the above operation can achieve the quick switching of the monocular night vision device 7 between the left and right eyes, greatly reducing the delay caused to the observation task during the switching of the monocular night vision device 7, ensuring 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 be more focused on observing the target, improving the overall task execution efficiency.

[0042] Further, as Figure 2 、 Figure 3 、 Figure 10 and Figure 11As shown in the figure, it is worth specifically explaining that a first card slot 104 and a second card slot 105 are provided on the side surface of the front panel 4. Both the first card slot 104 and the second card slot 105 are inserted and matched with the first permanent magnet block 201. The second card slot 105 is located at one of the electromagnet blocks 202, and the distance between the first card slot 104 and the other electromagnet block 202 is greater than or equal to the edge length of the sliding rod 101 along the length direction of the front panel 4. When the monocular night vision device 7 moves to switch between the left and right eyes, the monocular night vision device 7 is pulled outwards, so that the first permanent magnet block 201 is disengaged from the first card slot 104 or the second card slot 105, making the observation port 11 away from the eyes, avoiding the observation port 11 touching the face when the monocular night vision device 7 moves, and avoiding the face hindering the movement of the monocular night vision device 7. At this time, the limiting plate 103 and the first permanent magnet block 201 are in close contact with the two side surfaces of the front panel 4, so as to guide and limit the movement of the sliding rod 101 through the limiting plate 103 and the first permanent magnet block 201, ensuring the smooth movement of the sliding rod 101 and the monocular night vision device 7. When the monocular night vision device 7 moves to the other eye, at this time, the first permanent magnet block 201 is automatically snapped into the first card slot 104, so that the observation port 11 is re-fitted and pressed against the human eye, facilitating the human eye to use the monocular night vision device 7.

[0043] Further, as shown in Figure 3 , Figure 10 and Figure 11 it is worth specifically explaining that a second permanent magnet block 205 is fixed in both the first card slot 104 and the second card slot 105. The ends of the second permanent magnet block 205 and the first permanent magnet block 201 that are close to each other have opposite magnetic poles, and the second permanent magnet block 205 is magnetically attracted and matched with the first permanent magnet block 201. During specific operation, the magnetic attraction and cooperation between the provided second permanent magnet block 205 and the first permanent magnet block 201 are used to improve the stability of the first permanent magnet block 201 inserted in the first card slot 104 or the second card slot 105, ensuring the stability of the contact between the observation port 11 and the human eye. Further, the second permanent magnet block 205 can be replaceably set as an electromagnet block controlled by a small current controller 203, and the small current controller 203 is used to control whether to magnetically attract the first permanent magnet block 201, facilitating the disengagement of the first permanent magnet block 201 from the first card slot 104 or the second card slot 105.

[0044] Further, as shown in Figure 12 it is worth specifically explaining that a chamfer 207 is provided at the end of the first permanent magnet block 201 that is inserted and matched with the first card slot 104 and the second card slot 105. During specific operation, the provided chamfer 207 facilitates the insertion of the first permanent magnet block 201 into the first card slot 104 or the second card slot 105.

[0045] Further, as shown in Figure 2 and Figure 5As shown, it is worth specifically explaining that a through slot 206 is formed through the side surface of the sliding rod 101, and the through slot 206 is arranged in alignment with the first permanent magnet block 201; by providing the through slot 206, the attracting or repelling effect of the electromagnet block 202 at the end of the front plate 4 having the first card slot 104 on the first permanent magnet block 201 is improved.

[0046] Further, as shown in Figure 1 、 Figure 3 、 Figure 6 、 Figure 8 and Figure 10 As shown, it is worth specifically explaining that the lens cleaning assembly 3 includes a convex base 309 fixed to the middle of the front plate 4. A second cavity 310 is formed inside the convex base 309. A gas delivery pipe 304 communicating with the second cavity 310 is fixed to the top end of the convex base 309. One end of the gas delivery pipe 304 away from the second cavity 310 is fixed with a blowing and cleaning plate 301. A first cavity 303 communicating with the gas delivery pipe 304 is formed inside the blowing and cleaning plate 301. Blowing holes 302 communicating with the first cavity 303 are formed on the side surface of the blowing and cleaning plate 301 facing the front plate 4. There are multiple blowing holes 302, and the multiple blowing holes 302 are equidistantly distributed in the vertical direction. When the monocular night vision device 7 moves to the middle of the front plate 4, the air in the second cavity 310 is quickly compressed and delivered to the inside of the blowing and cleaning plate 301 through the gas delivery pipe 304, so that the air flow is quickly and evenly blown out to the lens of the monocular night vision device 7 through the first cavity 303 and the multiple blowing holes 302, thereby automatically blowing and cleaning the lens of the monocular night vision device 7, effectively removing dust, water vapor and tiny impurities adhering to the lens surface, ensuring that the lens always remains clear, thus improving the observation quality and accuracy. At the same time, the user does not need to frequently wipe the lens manually, reducing the frequency of manual wiping and cleaning, extending 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 continuously obtain a high-quality observation field of view.

[0047] Further, as shown in Figure 6 、 Figure 7 、 Figure 9 and Figure 10As shown, it is worth specifically explaining that a push rod 306 slidably penetrates through the bottom of the second cavity 310. One end of the push rod 306 located inside the second cavity 310 is fixed with a piston plate 308 that tightly fits against the inner wall of the second cavity 310. The other end of the push rod 306 located outside the second cavity 310 extends into the sliding groove 102. Two symmetrically distributed inclined guide grooves 305 are formed on the side surface of the sliding rod 101, and the inclined guide grooves 305 are in abutting cooperation with the push rod 306. 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 through the inclined guide groove 305, so that the piston plate 308 moves upward in the second cavity 310. Furthermore, the air in the second cavity 310 is rapidly compressed by the piston plate 308, so that the air flow in the second cavity 310 is conveyed to the inside of the cleaning plate 301 through the air delivery pipe 304 and is evenly blown out through a plurality of blowing holes 302 onto the lens of the monocular night vision device 7 for cleaning.

[0048] This solution has the following working process: When in use, the sliding rod 101 and the monocular night vision device 7 are fixed and positioned by the attraction between the first permanent magnet block 201 and the electromagnet block 202, so that the monocular night vision device 7 can be used stably; the sliding rod 101 can slide in the sliding groove 102, and the monocular night vision device 7 is driven to move synchronously by the sliding rod 101. Thus, the monocular night vision device 7 can be moved and adjusted to different ends of the front panel 4 through the cooperation of the sliding rod 101 and the sliding groove 102. After long-term observation with one eye, the monocular night vision device 7 can be conveniently transferred to the other eye for observation and use; when it is necessary to switch the monocular night vision device 7 from the right eye to the left eye, pull the monocular night vision device 7 outwards, so that the first permanent magnet block 201 is disengaged from the second card slot 105, and the observation port 11 is moved away from the eye. At this time, the opposite sides of the limiting plate 103 and the first permanent magnet block 201 are in contact with the two side surfaces of the front panel 4. Thus, the movement of the sliding rod 101 is guided and limited by the limiting plate 103 and the first permanent magnet block 201. A reverse current is input into the electromagnet block 202 close to the sliding rod 101 through the small current controller 203. At this time, the poles of the ends of the electromagnet block 202 close to the sliding rod 101 and the first permanent magnet block 201 that are close to each other are the same. Thus, a certain moving pushing force is applied to the monocular night vision device 7 through the repulsive force between the electromagnet block 202 and the first permanent magnet block 201, pushing the sliding rod 101 and the monocular night vision device 7 to move towards the other end of the front panel 4. At this time, a current is passed through the electromagnet block 202 on the convex plate 204 at the other end of the front panel 4, so that its magnetic pole is opposite to the magnetic pole of the end of the first permanent magnet block 201 that is close to it for attraction. Thus, the first permanent magnet block 201 on the sliding rod 101 is assisted to be adsorbed to the electromagnet block 202 at the other end of the front panel 4, so that the monocular night vision device 7 quickly and automatically moves and switches to the other end of the front panel 4, that is, the monocular night vision device 7 is quickly switched to the left eye position. At this time, the first permanent magnet block 201 is automatically snapped into the first card slot 104, so that the observation port 11 is reattached and pressed against the human eye, facilitating the left eye to observe and use the monocular night vision device 7. Correspondingly, when the monocular night vision device 7 is pulled outwards and the first permanent magnet block 201 is pulled out of the first card slot 104, the monocular night vision device 7 can be moved and switched from the left eye to the right eye through the above structure;

[0049] During the movement of the monocular night vision device 7, when the sliding rod 101 moves to the middle of the front panel 4, the inclined guide groove 305 on the sliding rod 101 contacts the ejector rod 306, and the ejector rod 306 is pushed upwards through the inclined guide groove 305. Thus, the piston plate 308 moves upwards in the second cavity 310, and then the air in the second cavity 310 is quickly compressed by the piston plate 308. The air flow in the second cavity 310 is delivered to the inside of the cleaning plate 301 through the air delivery pipe 304 and is evenly blown out through a plurality of blowing holes 302 onto the lens of the monocular night vision device 7 for cleaning.

[0050] Further, asFigure 7 and Figure 9 As shown, it is worth specifically stating that a return spring 311 is provided inside the second cavity 310 on the side of the piston plate 308 away from the ejector rod 306. The two ends of the return spring 311 are respectively in contact with the piston plate 308 and the end side surface of the second cavity 310. The end of the ejector rod 306 located in the sliding groove 102 is set as an arc 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 past the ejector rod 306, the piston plate 308 is pulled by the provided return spring 311 to move downward for reset, and the piston plate 308 is reset and moves to the bottom of the second cavity 310.

[0051] Furthermore, as Figure 3 shown, it is worth specifically stating that a fixing plate 10 is fixed on the side surface of the convex seat 309. The air delivery pipe 304 passes through the fixing plate 10 and the air delivery pipe 304 is fixed to the fixing plate 10. The stability of the air delivery pipe 304 is improved by the provided fixing plate 10.

[0052] Furthermore, as Figure 1 、 Figure 2 and Figure 3 shown, it is worth specifically stating that balls can be provided on the side surface of the sliding rod 101. The frictional resistance when the sliding rod 101 slides in the sliding groove 102 is reduced by the provided balls, and the smoothness of the adjustment of the monocular night vision device 7 is improved.

[0053] In summary: By means of the switching component 1, the monocular night vision device 7 can be moved to switch between the left and right eyes, greatly reducing the coordinated movements of the head and neck. Simply moving the monocular night vision device 7 can achieve the switching between the left and right eyes, making the adjustment operation more convenient and simple; during the process of the monocular night vision device 7 moving and switching, a certain moving pushing force is applied to the monocular night vision device 7 through the set increasing adjustment component 2, enabling the monocular night vision device 7 to quickly and automatically move and switch into place. The user does not need to manually move the monocular night vision device 7 throughout the process, effectively improving the efficiency and labor-saving nature of the movement and switching of the monocular night vision device 7, realizing the rapid switching of the monocular night vision device 7 between the left and right eyes, greatly reducing the delay caused to the observation task during the switching of the monocular night vision device 7, ensuring continuous and uninterrupted monitoring of the environment. At the same time, the convenient and rapid switching process of the monocular night vision device 7 enables the user to focus more on the observation target, improving the overall task execution efficiency; during the process of the monocular night vision device 7 moving and switching between the left and right eyes, the cleaning mirror component 3 is triggered to work by using the movement of the monocular night vision device 7. Thus, when the monocular night vision device 7 moves to the position of the cleaning mirror component 3, a certain amount of air is compressed and quickly blown onto the lens of the monocular night vision device 7 through the cleaning mirror component 3, thereby automatically blowing and cleaning the lens of the monocular night vision device 7, effectively removing the dust, water vapor and tiny impurities adhering to the lens surface, ensuring that the lens always remains clear, thereby improving the observation quality and accuracy. At the same time, the user does not need to manually wipe the lens frequently, reducing the frequency of manual wiping and cleaning, extending 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 continuously obtain a high-quality observation field of view.

[0054] The small current controller 203 can be purchased on the market. The small current controller 203 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed. Therefore, it will not be repeated in the specification.
