The top of the function shortcut keys and operation buttons of the button assembly 3 are marked with symbols or text, so that users can intuitively understand the operation function of each button.

[0041] The power switch assembly 5 has only one power button, and the rest of the structure is the same as that of the button assembly 3.

[0042] Furthermore, the battery assembly 9 also has an expansion function board that is electrically connected to the socket plate 4 in the middle; the expansion function board is used to connect and set other expansion function modules, such as setting an inertial navigation module on the expansion function board to realize the measurement of attitude, orientation and other information.

[0043] Furthermore, a wireless communication component (specifically a WIFI component 6) is provided on the lower side of the inner middle of the mirror body 1. The wireless communication component is electrically connected to the expansion function board. The bottom of the WIFI component 6 is encapsulated by a WIFI cover plate, which is made of ABS plastic to facilitate WIFI signal transmission.

[0044] Furthermore, a lens cover 14 is provided at the front end of the lens assembly 2; the lens cover 14 adopts a flip-top structure, and can be opened for observation and aiming when in use; a retaining ring is provided on the inside of the lens cover 14 for use when connected to the lens assembly 2 to prevent it from falling off.

[0045] Furthermore, the rear end of the eyepiece assembly 11 is provided with an eyecup 15, which allows the user to observe the target more comfortably, reducing or eliminating the effects of stray light, wind and sand, etc., and preventing light leakage from exposing the target at night; the eyecup 15 is designed with a connecting groove for fitting the connecting ring 23 to be connected to the scope. The groove opening is designed to be smaller than the outer diameter of the connecting ring 23, so that the eyecup 15 is securely connected and prevents it from falling off.

[0046] Furthermore, the lens assembly 2 includes a front lens tube 19, within which a focusing frame 21 is movably disposed. An objective lens assembly 16 is fixed within the focusing frame 21. The objective lens assembly 16 includes an objective lens frame and an objective lens group fixed within the objective lens frame by several spacers and retaining rings. An oval hole is provided on the side wall of the front lens tube 19, and a focusing screw 22 is disposed within the oval hole. The inner end of the focusing screw 22 is threadedly connected to the focusing frame 21, and the outer end of the focusing screw 22 passes through the front lens tube 19 and is connected to a screw ring 20 sleeved on the side wall of the front lens tube 19. A connecting ring 23 is threadedly connected to the rear end of the front lens tube 19, and the rear end of the connecting ring 23 is threadedly connected to the front end of the lens body 1. A focusing handwheel 18 is threadedly connected to the outer wall of the screw ring 20. The front end of the focusing handwheel 18 contacts the outer surface of the front lens tube 19, and the rear end of the focusing handwheel 18 contacts the outer surface of the connecting ring 23. The middle of the focusing handwheel 18... The scope is provided with an inwardly protruding boss. The boss of the focusing handwheel 18 is located in the groove formed between the outer rear end face of the front lens tube 19 and the outer front end face of the connecting ring 23. Washers 24 are provided between the outer rear end face of the front lens tube 19 and the boss of the focusing handwheel 18, and between the outer front end face of the connecting ring 23 and the boss of the focusing handwheel 18. (Optionally, the outer wall of the front lens tube 19 is provided with an outwardly protruding boss that contacts the front end of the focusing handwheel 18 in order to make the handwheel and the front lens tube fit together smoothly.) This makes the focusing handwheel 18 only able to rotate and not move axially. When the focusing handwheel 18 rotates, the screw ring 20 translates, which in turn drives the focusing screw 22 and the focusing frame 21 to translate together, thereby realizing the adjustment of the scope's focal length. The focusing frame 21 and the objective lens frame are designed to be connected with fine threads and have sufficient margin, which can easily, accurately and reliably correct the parallax of the scope.

[0047] A focusing spring 25 is provided on the outer periphery of the rear end of the objective lens assembly 16. The focusing spring 25 is located between the front lens tube 19 and the objective lens frame of the objective lens assembly 16, and is used to stabilize the focusing lens frame 21 and the objective lens assembly 16 to eliminate gaps. The front end of the focusing spring 25 contacts the focusing lens frame 21, and the rear end of the focusing spring 25 is limited by a spring retaining ring 26 that is threadedly fixed to the connecting ring 23.

[0048] An adjustment lens assembly 17 is fixedly connected to the front end of the front lens tube 19 by a threaded connection. The adjustment lens assembly 17 is equipped with a wedge-shaped glass. The adjustment lens assembly 17 is used to adjust the center deviation.

[0049] Lens sealing rings 27 are provided at the contact surfaces of the adjustment lens group 17 and the front lens tube 19, the front lens tube 19 and the focusing handwheel 18, the focusing lens frame 21 and the front lens tube 19, the focusing lens frame 21 and the objective lens frame, the connecting ring 23 and the focusing handwheel 18, and the connecting ring 23 and the lens body 1.

[0050] The objective lens group uses a photographic objective lens with F#=2. From front to back, the objective lens group consists of a first objective lens with positive optical power, a first cemented objective lens with positive optical power, a fourth objective lens with negative optical power, a fifth objective lens with positive optical power, and a second cemented objective lens with negative optical power. The fourth objective lens acts as a focusing lens; its slight forward and backward movement allows the objective lens to achieve clear imaging at both near and infinity. For the optical parameters of the objective lens group, please refer to [reference needed]. Figure 7 , Figure 8 .

[0051] Furthermore, the movement assembly 7 is fixed inside the mirror body by the movement retaining ring 8.

[0052] Furthermore, the rear end of the battery assembly 9 is connected and fixed to the inner wall of the mirror body 1 by three screws, and the front end of the battery assembly 9 is provided with a slot for placing the battery assembly baffle 10. The battery assembly baffle 10 is fixed to the mirror body 1 by screws.

[0053] Furthermore, the eyepiece assembly 11 includes an eyepiece frame 29, within which an eyepiece lens group 28 is fixedly mounted by several spacers (i.e., eyepiece spacers 30) and pressure rings (i.e., eyepiece pressure rings 31). Eyepiece sealing rings 32 are provided between the rearmost lens in the eyepiece lens group 28 and the rearmost pressure ring in the eyepiece frame 29, and at the contact surfaces between the eyepiece frame 29 and the lens body 1. Both the eyepiece spacers 30 and the eyepiece pressure rings 31 are dark-surface anodized. The eyepiece frame 29 and the lens body 1 are connected by multi-threaded connections, which increases the efficiency of diopter adjustment transmission. A reasonable adjustment distance is provided between the eyepiece frame 29 and the lens body 1 to ensure a sufficient diopter adjustment range.

[0054] A diopter adjustment ring 13 is fixedly connected to the outer rear end of the eyepiece frame 29; an eyepiece anti-reverse ring 12 is threadedly connected to the inner rear end of the lens body 1 to prevent the eyepiece assembly from unscrewing.

[0055] The eyepiece lens group 28 employs a Type I wide-angle eyepiece with a variable shape, enabling the optical system parameters to meet the structural requirements of a long exit pupil and a medium field of view of 35 degrees, with an exit pupil diameter of 6mm and an exit pupil distance of 56mm. The eyepiece back focal length is 7.2mm, and it offers ±5SD diopter adjustment. For the optical parameters of the eyepiece lens group, please refer to [link to relevant documentation]. Figure 9 , Figure 10 .

[0056] See the display interface of the scope. Figures 11-15 ;

[0057] The logical direction of each button in the button assembly corresponds to the button display direction on the display interface, so that control and display are consistent, forming an "integrated display and control" operation mode;

[0058] This scope features a rough rangefinding function. This function uses the silhouettes of deer, brown bears, wild boars, foxes, and rabbits as reference points, estimating distance by changing the overall size of the silhouettes. Following the interface prompts, the user changes the reference silhouette; the smallest silhouette indicates the farthest distance, and the largest silhouette indicates the closest distance. To ensure optimal performance, the design causes the silhouette to gradually shift to the left when magnified. Silhouettes exceeding the screen's size will move out of the center of the image, while smaller silhouettes will be moved to the center.

[0059] The scope of this invention has a simple and harmonious appearance, a stable and reliable structure, simple and efficient assembly, adjustable object distance, adjustable eyepiece diopter, good impact resistance and IP67 waterproof performance, and can be adapted to a variety of brackets to meet the needs of different users. It has an integrated display and control interface with four shortcut function keys and adopts a brand-new approximate ranging scheme, providing a good user experience.
