[0035] See also Figures 1 to 3 In some embodiments, the device body 40 includes AR glasses, AR helmets, handheld brackets and other devices. The night vision device 10 can be connected to the device body 40 to provide the user with night vision images, which is convenient for the user to move at night.

[0036] In some embodiments, a snap-fitting slot 440 may be provided on the device body 40 . The snap-fitting slot 440 is used to match with the night vision device 10 so as to limit the night vision device 10 to the device body 40 .

[0041] See also Figures 1 to 5 The present application provides a night vision device 10, which can be detachably electrically connected in a snap-in slot 440 of a device body 40. The night vision device 10 may include: a night vision device body 100 and a support leg 200. The night vision device body 100 is used to collect external environment information. The support leg 200 may include at least one pair of elastic limit arms 210 and an electrical connector 230. The two elastic limit arms 210 can be movably connected to the night vision device body 100, so that the two elastic limit arms 210 can be relatively close to or away from each other. The electrical connector 230 is used to realize the electrical connection between the night vision device body 100 and the device body 40. The two elastic limit arms 210 can be relatively far away from each other so as to be able to abut against the snap-in slot 440 on the device body 40, so that the night vision device 10 can be detachably connected to the device body 40, and the night vision device body 100 is electrically connected to the device body 40 through the electrical connector 230. The two elastic limiting arms 210 can be relatively close to each other so that the support leg 200 can be disengaged from the engaging groove 440 of the device body 40, so that the night vision device can be separated from the device body 40.

[0042] When installing and using the night vision device 10, the user moves the two elastic limiting arms 210 relatively close to each other so that the two elastic limiting arms 210 can guide the support leg 200 to extend into the engaging groove 440 of the device body 40. After the support leg 200 extends into the engaging groove 440, the two elastic limiting arms 210 are relatively far apart so that the two elastic limiting arms 210 can abut against the engaging groove 440 on the device body 40, thereby detachably connecting the night vision device 10 to the device body 40, and the night vision device body 100 is electrically connected to the device body 40 through the electrical connector 230. The installation efficiency of the night vision device 10 is effectively improved, and the user is convenient to use the night vision device 10.

[0043] After the night vision device 10 is used, the user can move the two elastic limiting arms 210 relatively close to each other so that the two elastic limiting arms 210 can be separated from the engaging grooves 440, so that the support legs 200 can be quickly moved out of the engaging grooves 440. This facilitates the rapid separation of the night vision device 10 from the device body 40, and effectively improves the disassembly efficiency of the night vision device 10.

[0045] See also Figures 1 to 6 In this embodiment, the night vision device body 100 is used to collect external environment information.

[0046] In some embodiments, the night vision device body 100 can be used to collect external environment information and convert the external environment information into night vision images so that the user can clearly identify objects at night. The night vision device body 100 can be an active infrared night vision device 10, a low-light night vision device 10 or an infrared thermal imager.

[0047] In this embodiment, the night vision goggles body 100 may be a cylindrical structure. The night vision goggles body 100 may extend along its axial direction. In some embodiments, the night vision goggles body 100 may be a prismatic structure. In other embodiments, in the axial direction of the night vision goggles body 100, the shape of the night vision goggles body 100 may also be other irregular shapes.

Figure 8 It is a structural schematic diagram of the supporting foot and the first protective shell of the night vision device of the utility model. Fig. 9 yes Figure 8 A structural schematic diagram of another perspective of the structure shown in .

[0049] See also Figures 1 to 9In this embodiment, the night vision device 10 may include a support leg 200. The support leg 200 may be connected to the peripheral side wall of the night vision device body 100 so as to limit the night vision device body 100 to the device body 40.

[0050] The support leg 200 may include at least one pair of elastic limiting arms 210. The pair of elastic limiting arms 210 may include two elastic limiting arms 210 arranged opposite to each other. The two elastic limiting arms 210 may extend in the same direction. The two elastic limiting arms 210 may be relatively close to or relatively far away from each other, so as to facilitate the connection and disassembly of the night vision device 10 and the device body 40.

[0051] See also Figures 1 to 9 In some embodiments, the elastic limiting arm 210 can extend along the axial direction of the night vision goggles body 100 to facilitate the engagement and separation of the elastic limiting arm 210 and the engagement groove 440, thereby facilitating the installation and separation of the night vision goggles body 100 and the device body 40.

[0052] See also Figures 1 to 9 In this embodiment, one end of the two elastic limiting arms 210 can extend in an arc shape toward each other to form a guide portion 211. The guide portion 211 can guide the support leg 200 to extend into the engaging groove 440, thereby effectively improving the installation efficiency of the night vision device 10.

[0053] The user can apply force to the two guide parts 211 to make the two guide parts 211 relatively close to each other, so as to facilitate the foot 200 to enter and move out of the engaging groove 440. When the user stops applying force to the guide parts 211, the two guide parts 211 can be relatively separated by their own elastic force, so as to facilitate the mutual limitation of the elastic limiting arm 210 and the engaging groove 440.

[0054] See also Figures 1 to 9 In this embodiment, a limiting groove 212 can be provided on the opposite side of the two elastic limiting arms 210. The limiting groove 212 is used to match the side wall of the engaging groove 440. Thus, the support leg 200 can be stably and reliably limited in the engaging groove 440, effectively improving the connection strength between the night vision device 10 and the device body 40, and facilitating the use of the user.

[0055] In some embodiments, the limiting groove 212 can extend along the extension direction of the elastic limiting arm 210. When the limiting groove 212 and the engaging groove 440 are mutually engaged and limited, the two inner end walls of the limiting groove 212 can abut against the two end walls of the engaging wall 420. Thus, the night vision device body 100 can be limited to move along the axial direction of the night vision device body 100, the connection strength between the limiting groove 212 and the engaging groove 440 is improved, and the connection reliability between the night vision device 10 and the device body 40 is ensured.

[0056] In other embodiments, the limiting groove 212 may extend toward the night vision device body 100 to pass through a side wall of the elastic limiting arm 210 close to the night vision device body 100. The limiting groove 212 may extend away from the night vision device body 100 to pass through a side wall of the elastic limiting arm 210 away from the night vision device body 100.

[0057] On the one hand, it is convenient for the limiting groove 212 and the engaging groove 440 to engage with each other, thereby improving the installation efficiency of the night vision device 10. On the other hand, after the limiting groove 212 and the engaging groove 440 are mutually limited, part of the device body 40 can pass through the limiting groove 212 to be pressed on a side wall of the elastic limiting arm 210 close to the night vision device body 100, thereby pressing the support leg 200 in the engaging groove 440, thereby improving the connection strength and stability between the night vision device 10 and the device body 40.

[0058] When the night vision device 10 is mounted on the device body 40 , the two guide portions 211 are relatively close to each other, and the guide portion 211 extends between the two engaging walls 420 , so that the support leg 200 can move in the engaging groove 440 . The two engaging walls 420 squeeze the two guide portions 211 .

[0059] When the support leg 200 moves into the engaging groove 440, the limiting groove 212 engages with the engaging groove 440, and the guide portion 211 moves away from each other under the action of the elastic force, so that the two end walls of the limiting groove 212 respectively abut against the two end walls of the engaging wall 420, and the two engaging walls 420 are limited in the limiting groove 212, so that the device body 40 can limit the movement of the night vision device 10 along the axial direction of the night vision device body 100.

[0060] When the night vision device 10 is disassembled, the two guide parts 211 are relatively close to each other, so that the two guide parts 211 can be located between the two engaging walls 420, thereby facilitating the support leg 200 to move out of the engaging groove 440, thereby improving the separation efficiency of the night vision device 10 and the device body 40.

[0061] In some embodiments, the support leg 200 may include multiple pairs of elastic limiting arms 210. The device body 40 may be provided with multiple engaging grooves 440 relative to the multiple pairs of elastic limiting arms 210. The multiple pairs of elastic limiting arms 210 can be respectively engaged in the multiple engaging grooves 440 to improve the connection strength and reliability between the night vision device 10 and the device body 40.

[0062] In some embodiments, any two pairs of elastic limiting arms 210 may be arranged at intervals. In some embodiments, any two pairs of elastic limiting arms 210 may be arranged at intervals.

[0063] In other embodiments, multiple pairs of elastic limiting arms 210 may be arranged in sequence on the same side. In other embodiments, the lengths of the elastic limiting arms 210 on the same side may be different, so that multiple pairs of elastic limiting arms 210 can be engaged in sequence.

[0064] See also Figures 1 to 9 In this embodiment, a sliding surface 213 may be provided on the opposite side of the two elastic limiting arms 210. The sliding surface 213 may extend along the extension direction of the elastic limiting arms 210 so as to pass through both ends of the elastic limiting arms 210. The sliding surface 213 may be provided relative to the pressing wall 430 so that the pressing wall 430 can be pressed against the sliding surface 213, thereby pressing the support leg 200 on the base 410.

[0065] In some embodiments, on the surface of the elastic limiting arm 210 facing the night vision device body 100, the opposite sides of the two elastic limiting arms 210 can be recessed to form a sliding surface 213. This facilitates the alignment, movement and limiting of the pressing wall 430 and the sliding surface 213.

[0066] In other embodiments, the sliding surface 213 may form a guiding slope 214 at a portion of the guiding portion 211. In the direction from the center of the elastic limiting arm 210 to the end of the elastic limiting arm 210, the guiding slope 214 is arranged to be inclined in a direction away from the night vision device body 100. When the guiding portion 211 extends into the engaging groove 440, it is convenient for the holding wall 430 to be pressed on the sliding surface 213 through the guiding slope 214. Thus, the installation efficiency between the support leg 200 and the engaging groove 440 is improved.

[0067] See also Figures 1 to 9 In this embodiment, one end of the elastic limiting arm 210 away from the guide portion 211 may be protruded to form a supporting portion 215. The supporting portions 215 on the two elastic limiting arms 210 extend in opposite directions. The supporting portion 215 can form an end wall of the limiting groove 212 to support the end wall of the engaging wall 420. Thus, the support leg 200 can be limited in the engaging groove 440, ensuring the connection strength between the support leg 200 and the engaging groove 440.

[0068] In some embodiments, the guide portion 211 may be arranged at intervals with the abutting portion 215. The guide portion 211, the elastic limiting arm 210 and the abutting portion 215 are surrounded to form a limiting groove 212.

[0069] In some embodiments, the abutting portion 215 may extend to one end of the sliding surface 213 so as to abut against the end wall of the pressing wall 430 , thereby improving the connection strength, reliability and stability between the supporting leg 200 and the engaging groove 440 .

[0070] See also Figures 1 to 9In this embodiment, the support leg 200 may further include a support plate 220 . The support plate 220 is located between the pair of elastic limiting arms 210 so as to support the elastic limiting arms 210 against the inner wall of the engaging groove 440 .

[0071] When the support leg 200 is inserted into the engaging groove 440, the support plate 220 can support the two elastic limiting arms 210. The two elastic limiting arms 210 can abut against the inner wall of the engaging groove 440, thereby firmly and stably limiting the night vision device 10 on the device body 40, and ensuring the connection strength between the night vision device 10 and the device body 40.

[0072] In some embodiments, the support plate 220 may be connected to the end of the elastic limiting arm 210. In other embodiments, the support plate 220 is located at the end of the elastic limiting arm 210 away from the guide portion 211. On the one hand, it is convenient for the relative movement of the guide portion 211. On the other hand, it can improve the connection strength between the support leg 200 and the engaging groove 440.

[0073] In some embodiments, the support plate 220 may extend along the extension direction of the elastic limiting arm 210 to improve the structural strength and reliability of the support leg 200 and ensure the connection strength between the night vision device 10 and the device body 40.

[0074] In some embodiments, a side wall of the support plate 220 facing away from the night vision device body 100 may be flush with a side wall of the elastic limiting arm 210 facing away from the night vision device body 100, so that the support leg 200 can be attached to the bottom wall of the engaging groove 440, thereby preventing external dust and debris from penetrating between the support leg 200 and the device body 40.

[0075] See also Figures 4 to 9 In this embodiment, the support plate 220 can protrude between the two elastic limiting arms 210 to form a limiting portion 221. The limiting portion 221 can be spaced apart from the elastic limiting arms 210. The limiting portion 221 can stop the movement of the two elastic limiting arms 210 in a relatively close manner. This can prevent the two guide portions 211 from moving toward each other excessively, thereby preventing the guide portions 211 from breaking. The safety and reliability of the support leg 200 are ensured.

[0076] In some embodiments, the support plate 220 can be integrally formed with the elastic limiting arm 210 , thereby effectively improving the structural strength of the support leg 200 .

[0109] See also Figures 1 to 10 In the present invention, when the night vision device 10 needs to be installed on the device body 40, the user squeezes the guide parts 211 of the two elastic limiting arms 210 to bring the two guide parts 211 closer to each other. Then the support foot 200 is moved toward the engaging groove 440 so that the guide part 211 extends into the engaging groove 440.

[0110] When the support leg 200 moves into the engaging groove 440, the two guide parts 211 move away from each other under the action of their own elastic force. When the support leg 200 extends into the engaging groove 440 and the abutting part 215 abuts against the end wall of the engaging wall 420 and the pressing wall 430, the engaging wall 420 engages and is limited in the limiting groove 212, and the end wall of the engaging wall 420 close to the guide part 211 abuts against the end wall of the limiting groove 212 close to the guide part 211, thereby safely, stably and reliably limiting the support leg 200 on the device body 40.

[0111] When the night vision goggles body 100 is connected to the device body 40 via the legs 200 , the elastic pins on the legs 200 extend out of the support plate 220 and are electrically connected to the electrical connection slots 411 on the base 410 , so that energy and data can be exchanged between the night vision goggles body 100 and the device body 40 .

[0113] When the night vision device 10 needs to be disassembled, the user applies force to the two guide parts 211 to make the two guide parts 211 relatively close to each other, and the end wall of the limit groove 212 close to the guide part 211 moves toward each other and away from the engaging wall 420. Then, force is applied to the night vision device 10 to make the support foot 200 escape from the engaging groove 440, and the night vision device 10 is separated from the device body 40. Thus, the disassembly efficiency of the night vision device 10 can be effectively improved.

[0114] In the present application, when the user installs and uses the night vision device 10, the two elastic limiting arms 210 are relatively close to each other so that the elastic limiting arms 210 can be moved into the engaging groove 440. Afterwards, the two elastic limiting arms 210 are relatively far away from each other so that the two elastic limiting arms 210 can abut against the engaging groove 440 on the device body 40, and the night vision device 10 is connected to the device body 40. Thereby, the installation efficiency of the night vision device 10 is effectively improved. When the user disassembles the night vision device 10, the two elastic limiting arms 210 are relatively close to each other so that the support leg 200 can be quickly moved out of the engaging groove 440, thereby facilitating the rapid separation of the night vision device 10 from the device body 40, and effectively improving the disassembly efficiency of the night vision device 10.
