[0002] Night vision goggles are devices that can enhance visual ability in low-light or completely dark environments, helping users to observe and monitor at night, allowing users to observe and identify targets at night or in low-light conditions. According to the working principle, they are divided into active and passive types. The active type is that the night vision goggles actively emit infrared light, and form images by reflecting the infrared light back. The system is composed of infrared laser illuminators, zoom lenses, ultra-low-light infrared cameras and other equipment. The purpose of night lighting is achieved by optically diffusing laser point light sources, and the characteristics of the target can be displayed more clearly. Infrared night vision goggles in the prior art can generally be divided into head-mounted and handheld types. Conventional handheld night vision goggles are often used with a handheld mirror body, and a handle is generally provided at the bottom or one side of the night vision goggles for easy holding.

[0003] For example, Chinese patent publication number CN217238519U discloses a handheld low-light night vision device, which includes a night vision device body, an objective lens is arranged on the front face of the night vision device body, an eyepiece is arranged on the back face of the night vision device body, a lifting strap is arranged on the upper end of the night vision device body, a display screen and an anti-collision strip are arranged on the side face of the night vision device body, the display screen and the night vision device body are rotatably connected by a damping hinge, a storage slot is arranged on the lower end face of the night vision device body, a handle is arranged in the storage slot, a buckle is arranged on the side of the storage slot close to the objective lens, a pin hole is arranged on the side face of the night vision device body away from the display screen, a sliding pin is arranged in the pin hole, and a pin is slidably connected to the side face of the handle. The present invention cooperates with the lifting strap through the rotationally connected handle structure, and the handle is stored in the storage slot for easy carrying of the device, and the handle is convenient to hold after being rotated outward, thereby improving the stability of holding the device.

[0004] For example, Chinese patent publication number CN209731430U discloses a portable handheld thermal imaging night vision device, which includes a body, a connecting seat and a recording screen. The left side of the body is connected to a viewing lens, and the right side of the body is installed with a camera lens, and a connecting block is installed below the body, and a supporting block is connected below the connecting block, and a hand-held handle is connected below the supporting block, a slide rail is installed at the rear of the body, and a fixed seat is installed behind the slide rail, the connecting seat is located at the rear of the body, a fixed block is provided on the rear surface of the connecting seat, and a recording screen is installed behind the connecting seat. The hand-held handle of the portable handheld thermal imaging night vision device can be folded to save the space occupied by the device, and the height of the hand-held handle can be adjusted.

[0005] For example, Chinese patent publication number CN218041555U discloses a handheld thermal imaging night vision device, in which the objective lens group is arranged in the objective lens, the body of the device has a built-in thermal imaging component and is connected to the objective lens through a bayonet, and the eyepiece is connected to the rear end of the body of the device; the fixed block is fixed to the bottom or side of the body of the device, the connecting block is detachably fixed to the bottom of the fixed block, the top of the handle is hinged to the connecting block and has a battery compartment, the top of the handle is provided with a connecting part I electrically connected to the contacts in the battery compartment, the connecting block is provided with a connecting part II electrically connected to the connecting part I, and the connecting part II is electrically connected to the thermal imaging component.

The two unfolded semi-cylindrical handles 8 form an eight-shaped support for the night vision goggles body 5, so that the semi-cylindrical handles 8 provide auxiliary support for the night vision goggles body 5, and support the night vision goggles body 5 to a height suitable for the eyes of the user in a prone position, so that the user can use the night vision goggles body 5 in a prone position for night vision monitoring, which greatly reduces the support of the night vision goggles body 5 by hand, avoids hand fatigue caused by long-term support of the night vision goggles body 5 for observation, and is convenient to use. At the same time, the support of the semi-cylindrical handles 8 prevents the night vision goggles body 5 from contacting the ground and being contaminated with mud on the ground, effectively improving the protection of the night vision goggles body 5 when the night vision goggles body 5 is used in a prone position.

[0045] Further as Figure 5 As shown, it is worth explaining in detail that the sides of the two semi-cylindrical handle rods 8 that are close to each other are set as flat sides and the first permanent magnet blocks 305 are fixed on the flat sides, and the two first permanent magnet blocks 305 are arranged to be attracted to each other; when the two semi-cylindrical handle rods 8 are combined into a complete handle, the two semi-cylindrical handle rods 8 are attracted to each other through the two first permanent magnet blocks 305, thereby ensuring the stability of the two semi-cylindrical handle rods 8 when closed, making it convenient for people to hold and lift the semi-cylindrical handle rods 8.

[0046] Further as Figure 5 As shown, it is worth explaining in detail that a plurality of symmetrically distributed rubber top columns 306 are fixed on the flat side surface of one of the semi-cylindrical handle rods 8; during specific operation, the rubber top columns 306 are set to prevent the first permanent magnet blocks 305 on the two semi-cylindrical handle rods 8 from colliding and breaking, thereby improving the protection of the first permanent magnet block 305.

[0047] Further as Figure 4 , Figure 5 , Fig.10 and Fig.11As shown, it is worth specifically explaining that the cover assembly 4 includes a cover plate 405 for covering and protecting the objective lens 7, the area of ​​the cover plate 405 is larger than the port area of ​​the objective lens 7, a first support plate 407 and a second support plate 408 are fixed on the outer wall of the night vision device body 5, a rack 402 is slidably connected in the first support plate 407, a large gear 401 meshingly connected to the rack 402 is fixed on one end of the first shaft 103, and a third shaft 40 is rotatably connected in the second support plate 408. 4, a pinion 403 meshing with the rack 402 is fixed at one end of the third shaft 404, and a cover plate 405 is fixed on an end of the third shaft 404 away from the pinion 403; the cover plate 405 opens and closes the objective lens 7 by rotating 180 degrees around the third shaft 404 in both positive and negative directions, and when the semi-cylindrical handle 8 rotates and folds, the semi-cylindrical handle 8 rotates and adjusts 90 degrees, and the semi-cylindrical handle 8 drives the first shaft 103 to rotate 90 degrees, and the first shaft 103 The synchronous large gear 401 is driven to rotate ninety degrees. The size of the large gear 401 is set to be twice that of the small gear 403. Therefore, the large gear 401, the rack 402, the small gear 403 and the third shaft rod 404 cooperate to drive the cover plate 405 to rotate and adjust one hundred and eighty degrees, so that the cover plate 405 is completely covered on the port of the objective lens 7, and the objective lens 7 is automatically covered and protected by the cover plate 405, so that the rotation and folding of the semi-cylindrical handle rod 8 and the covering and protection operation of the objective lens 7 are combined into one, so that the user can automatically complete the covering of the objective lens 7 while folding the semi-cylindrical handle rod 8, eliminating the operation of manually covering the objective lens 7 for protection. Through the anti-fool design, the risk of missing the covering of the objective lens 7 and causing the objective lens 7 to be scratched or contaminated during carrying or storage is effectively avoided. When the night vision device body 5 needs to be used and the semi-cylindrical handle rod 8 is rotated to open, the objective lens 7 is automatically opened, eliminating the operation of manual opening, and facilitating the use of the night vision device body 5.

[0048] This solution has the following working process: when in mobile use, the end plate 202 is pulled by the spring 203, so that the inner end of the insertion rod 204 is firmly inserted into the insertion hole 206, thereby locking the first protrusion 102 and the first rotating seat 101 into one, and then the semi-cylindrical handle rod 8 and the night vision device body 5 are locked into one in the rotation and folding direction. The two semi-cylindrical handle rods 8 are combined to form a complete handle for the user to hold, so that it is convenient for the user to hold the night vision device body 5 for mobile use. When the handle needs to be folded, the end plate 202 is pulled outward to make the inner end of the insertion rod 204 disengage from the insertion hole 206, and the lock of the first shaft rod 103 is released, so that the two semi-cylindrical handle rods 8 can be folded. When the semi-cylindrical handle rod 8 is rotated and folded to the set position, the inner end of the insertion rod 204 is automatically inserted into the other insertion hole 206 under the action of the spring 203, so that the folded semi-cylindrical handle rod 8 is locked.
