[0036] Please refer to Figures 1 to 6 , in an embodiment of the present utility model, the night vision device includes:
[0037] A housing 100, within which there is an installation cavity 11, an objective lens opening 12 communicating with the front end of the installation cavity 11, and a display opening 13 communicating with the front end and the rear end of the installation cavity 11;
[0038] A night vision imaging module 200, including an objective lens 21, a main control board, and a display screen 22. The objective lens 21 is disposed at the objective lens opening 12, the main control board includes an image processor and is disposed in the installation cavity 11, the display screen 22 is disposed at the display opening 13 and is electrically connected to the main control board; and
[0039] A first guiding module 300, configured as a mechanical compass 31 and exposed at the display opening 13, or configured as an electronic compass and disposed on the main control board, and the image 32 of the electronic compass can be displayed on the display screen 22.
[0040] In the technical solution of the present utility model, when the first guiding module 300 is a mechanical compass 31, the mechanical compass 31 is exposed from the display port 13 so that when the ambient light is weak, the light source at the display screen 22 can illuminate the dial of the mechanical compass 31. When the user holds the night vision device and observes the image on the display screen 22, the dial of the mechanical compass 31 can also be seen to clarify the user's own orientation. When the first guiding module 300 is an electronic compass, the display screen 22 can display the azimuth image measured by the electronic compass so that the user can observe the azimuth information from the display screen 22.
[0041] In the first embodiment, when the first guiding module 300 is configured as a mechanical compass 31, the display screen 22 is provided with an avoidance notch 221 corresponding to the mechanical compass 31, and the mechanical compass 31 is received in the avoidance notch 221. At this time, the inner walls of the avoidance notch 221 and the display port 13 jointly clamp the mechanical compass 31. Further, the flat cross-sectional shape of the casing of the mechanical compass 31 in the first guiding module 300 is configured as a square, and the shape of the avoidance notch 221 is also correspondingly configured as a square to reduce the production difficulty of the display screen 22 with a special shape. Moreover, the mechanical compass 31 with a square casing can cooperate with the square frames of the display screen 22 and the display port 13 to facilitate the correct placement of the dial of the mechanical compass 31 and can echo the shape of the display screen 22 in appearance, providing an aesthetic feeling. In other embodiments, it can also be that an avoidance port is provided at the display port 13, and the avoidance notch 221 and the avoidance port enclose a receiving space to receive the mechanical compass 31; or the avoidance notch 221 is provided at the display port 13. In another embodiment, it can also be that the flat cross-sectional shape of the casing of the mechanical compass 31 is circular, and the avoidance notch 221 is correspondingly set as an arc.
[0042] In the first embodiment, a sealing strip is clamped between the periphery of the mechanical compass 31 and the avoidance notch 221 and the display port 13 to prevent moisture from entering the installation cavity 11 during use.

In other embodiments, the control button may not be provided.
[0046] In the second embodiment, the control button includes a pressing cap and a triggering part. The top side surface of the housing 100 is provided with a second guide module 400 configured as a mechanical compass 31, and the pressing cap and the second guide module 400 are configured as the same structure. That is, by pressing the pressing cap, it is possible to control that the image 32 with the electronic compass is not displayed on the display screen 22. At the same time, the pressing cap can provide orientation information when the ambient light is sufficient. In other embodiments, the pressing cap and the second guide module 400 may not be configured as the same structure.

An inner concave arc surface is provided on the side of the light shield 500 away from the housing 100, and the inner concave arc surface can fit the head curve of the human body. The light shield 500 can block and gather the light emitted by the screen lock, so that when wearing the night vision device, the user is not affected by the ambient light around, and the user can observe the night vision image displayed on the display screen 22 more attentively. When the first guide module 300 is configured as a mechanical compass 31, the gathered light can better display the dial of the mechanical compass 31. In other embodiments, the light shield 500 may not be provided.
[0049] In one embodiment, the night vision device is configured as an active infrared night vision device. The night vision imaging module 200 further includes an infrared lamp 600 and a convex lens 700. The convex lens 700 is exposed on the front end face of the housing 100.
