The display module 500 is electrically connected to the image sensor module 220, and the display module 500 is fixedly mounted on the infrared mounting base 310. The optical axis of the infrared light source module 400 is arranged side by side with the optical axis of the lens assembly 210.
In the present embodiment, it should be noted that, the lens barrel 100 extends in the front-back direction, and the front and the back are both referred to as the orientation of the user when using the night vision device 10, and the end of the lens barrel 100 away from the user is the front and the end close to the user is the back. The lens barrel 100 is used to house and mount optical members such as the imaging module 200. The cross-sectional shape of the lens barrel 100 may be circular, polygonal, etc., and the length and the inner diameter of the lens barrel 100 may be selected and designed according to actual requirements, which is not specifically limited herein. The front end of the lens barrel 100 is provided with a mounting opening 120, that is, the front end of the lens barrel 100 is open to form the mounting opening 120, and the mounting opening 120 is arranged forward as a whole to ensure enough light to enter the lens barrel 100. For convenience of description, the end of the lens barrel 100 with the mounting opening 120 is defined as a light incident end. It can be understood that, when the lens barrel 100 is mounted on a white sighting telescope for use, the light incident end of the lens barrel 100 is sleeved on the eyepiece end of the white sighting telescope, and the light path entering the mounting opening 120 is the light path of the eyepiece of the white sighting telescope. The night vision device 10 can also be used directly as an eyepiece system for a white sighting telescope. Of course, when the night vision device 10 is used alone, the light path entering the light incident end is a natural light path of the target location. It should be noted that, when the usage scenario of the night vision apparatus 10 is different, the corresponding lens assemblies 210 in the lens barrel 100 may also be different, and the specific structure of the lens assemblies 210 is not limited herein.
The imaging module 200 is mounted in the inner cavity 110, and particularly, can be mounted at an end of the inner cavity 110 far away from the mounting opening 120. By disposing the imaging module 200 at an end of the lens barrel 100 away from the mounting opening 120, the imaging module 200 and the infrared light source module 400 are disposed at two ends of the lens barrel 100, so that the gravity distribution of the entire lens barrel 100 in the axial direction is more uniform. Of course, in some embodiments, the imaging module 200 may be mounted in the middle of the inner cavity 110 or at an end adjacent to the mounting opening 120. Generally, the lens assembly 210 is movably mounted in the lens barrel 100 along the axis of the lens barrel 100, and an adjusting window is disposed on the outer wall of the lens barrel 100 corresponding to the lens assembly 210, through which a user can rotate an adjusting handwheel to drive the lens assembly 210 to move along the axis of the lens barrel 100, so as to adjust the distance between the lens assembly 210 and the image sensor assembly 220, thereby achieving focusing. The adjustment window is disposed closer to the user by disposing the imaging module 200 at an end of the lens barrel 100 away from the light incident end, so as to facilitate the user's operation.
Specifically, the optical axis of the lens assembly 210 coincides with the axis of the lens barrel 100, and the image sensor assembly 220 is located at the rear side of the lens assembly 210. Thus, the light path entering the lens assembly 210 can directly enter the image sensor assembly 220 without turning, so that the requirement on the size of the installation space in the lens barrel 100 is smaller, the space in the axial direction of the lens barrel 100 can be fully utilized, and the installation structure in the whole lens barrel 100 is more compact and the volume is smaller.
The inner ring 320 is embedded inside the mounting opening 120, that is, the outer wall surface of the inner ring 320 is matched with the inner wall surface of the light incident end, so that the coaxiality of the inner ring 320 and the lens barrel 100 can be ensured. It should be noted that, the infrared mount 310 protrudes from the outer circumferential surface of the lens barrel 100 in the radial direction of the lens barrel 100, and the infrared mount 310 and the inner ring 320 may be arranged in a staggered manner on the axis of the lens barrel 100, or the infrared mount 310 is arranged opposite to the lens barrel 100 in the radial direction of the lens barrel 100. That is, the infrared mount 310 may be specifically located at upper, lower, left, right, front upper, front lower, etc. positions of the lens barrel 100.
