[0002] In order to reduce the risk of exposure of shooters, make the method of determining targets not only rely on people observing targets, improve the target's recognizability, and expand the application environment of red dot sights, people have applied thermal imaging technology to traditional red dot sights. This is mainly done by transmitting the images captured by thermal imaging technology to traditional red dot sights, and using the lens of the red dot sight to reflect them to the user to assist in aiming, while retaining the inherent aiming function of the red dot sight, so that the thermal imaging image is integrated with the red dot's inherent red dot aiming. At the same time, with the help of the electronic focusing function of thermal imaging technology, the accuracy of aiming is greatly improved, especially effectively avoiding the adverse effects of ambient light and shooting distance, such as a sight with thermal imaging function disclosed in the invention patent application with patent application number 202210970881.4.

[0033] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose, the specific implementation methods, structural features and effects of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0034] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "aligned", "overlap", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features; and in the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0037] Existing fusion sights (i.e., red dot sights with thermal imaging and low-light-level night vision aiming functions, where the thermal imaging and low-light-level night vision aiming parts are called the new part and the red dot sight is called the traditional part) are relatively large in size, regardless of whether the new part and the traditional part are integrated with a common shell or separated by a circuit interface. When in use, they all appear as a whole and cannot be separately installed on a firearm. Therefore, the current fusion sights are not suitable for compact pistols and still need to be fixedly connected to each other, making it inconvenient to disassemble and assemble the two parts. To overcome this drawback, the present embodiment provides a pistol fusion sight as shown in FIG1 , comprising a split fusion sight (i.e., a split fusion sight similar to the split fusion sight described in Chinese Utility Model Patent No. 202223132354.0) and an illumination module 1. The eyepiece assembly of the split fusion sight, i.e., the reflective sight 8 in this embodiment, is clamped to the top rear end of the pistol slide 6. The aiming assembly of the split fusion sight, i.e., the camera assembly 2 in this embodiment, is disposed at the front bottom of the pistol grip 30. As can be seen from FIG1 , the camera assembly 2 and the illumination module 1 are stacked and disposed above and below in a connecting shell 3, i.e., they share a common housing. The two modules are connected and assembled together for easy installation and portability. The illumination module, as shown in FIG3 , is substantially identical to existing illumination modules and primarily comprises a battery compartment 14 and a light source assembly 15. The light source here can be an LED lamp or a laser diode.

[0038] Combined with 2, it can be further known that a first rail 4 is provided on the top surface of the connecting shell 3, and a transverse protrusion 5 is provided in the rail groove of the first rail 4; wherein, the first rail 4 is used to be clamped on the axial rail 7 provided on the bottom surface of the front end of the handle 30, and the transverse protrusion 5 is used to be accommodated in the transverse groove provided on the axial rail 7, so as to realize axial limitation of the camera assembly 2.

[0039] A second rail 16 is provided at the bottom of the reflective sight 8 of the split fusion sight shown in FIG1 , so as to fix the reflective sight 8 on the rear end top surface of the slide 6 .

[0040] In order to transmit the target image to the user, this embodiment provides a first wireless communication module connected to the image sensor digital movement 12 (the front end of which is a thermal imaging or low-light night vision lens assembly 13) shown in Figure 3 in the existing camera assembly 2; similarly, a second wireless communication module connected to the display screen is provided in the reflective sight 8, which is used to transmit the image data from the image sensor digital movement 12 to the display screen 20 shown in Figure 6. The display screen 20 projects the image onto the reflective lens 21 of the traditional internal red dot sight and emits it from the protective glass at the eyepiece end for the user to view.

[0041] Since the aiming function is distributed between the camera assembly 2 and the reflective sight 8, the camera assembly 2 realizes the shooting of the target and wirelessly transmits the image information to the display screen 20 of the reflective sight 8. The image information is projected onto the reflective lens 21 through the display screen 20 and fused with the actual object image incident from the front of the reflective sight 8.

[0042] Because the camera assembly 2 and the imaging reflective sight 8 are separate components mounted on the upper and lower parts of the firearm, there is a certain degree of coaxiality deviation (up and down or left and right), which can cause the image and the actual object to be misaligned, resulting in misalignment and affecting observation and aiming. To overcome this drawback, this embodiment solves this problem through two solutions. First, an adjustment mechanism is added to the camera assembly 2 shown in Figure 5, allowing the camera optical axis to be fine-tuned to a certain pitch and horizontal angle. In addition, a display area outside the screen frame of the reflective sight 8 is reserved as an adjustment range for the fusion of the displayed image and the target object image. Through these two combined methods, even if the installation causes optical axis misalignment, the user can achieve image fusion through adjustment, achieving more accurate observation and aiming. The specific implementation diagram of this method is shown in Figure 5. A first adjustment screw 17 and a second adjustment screw 18 are respectively provided on both sides of the top front end of the connecting shell 3; and an adjustment spring 19 (helical return spring) is provided between the bottom of the cavity for mounting the camera assembly 2 of the connecting shell 3 and the bottom of the thermal imaging or low-light-level night vision lens assembly 13 of the camera assembly 2, to cooperate with the first adjustment screw 17 and the second adjustment screw 18 to adjust the camera optical axis of the thermal imaging or low-light-level night vision lens assembly 13, so that the projected image of the display screen 20 is fused with the actual image. When the projected image and the actual image are fused, the auxiliary display frame of the display screen shown in Figure 6 is used, specifically, a screen maximum display area frame 22, i.e., a rectangular frame, is provided. ABCD , the screen display area adjustment frame 23 is a rectangular frame abcd , and the screen actual display area frame 24 is a rectangular frame efgh , so that the position of the projected image can be adjusted to make it coincide with the actual image. When making a real object, the largest display area frame 22 of the screen is a rectangular frame ABCD The actual display area frame 24 of the screen is a rectangular frame. efgh In the initial state of the display screen, the rectangular frame 22 is located in the largest display area frame of the screen ABCD In the middle of the screen display area, the adjustment frame 23 is a rectangular frame abcd Indicates that after the display area is adjusted, the maximum display area of ​​the screen is within the rectangular frame 22 ABCD Therefore, the actual object image projected onto the reflective lens can be used as a reference to adjust the position of the projected image so that the projected image projected onto the reflective lens by the display coincides with the actual object image, that is, only one object image is finally seen on the screen, and it is in the actual display area frame 24 of the screen, that is, the rectangular frame efghThe actual display frame 24 of the display screen is a rectangular frame. efgh The maximum display frame on the screen is 22 rectangular frames ABCD Adjustable up, down, left and right.

[0043] As can be seen from Figures 1 and 4, a power switch 9 is provided on one side of the connecting shell 3, and a control button 10 and a charging port 11 are provided on the other side. Similarly, the reflective sight 8 has a dedicated power switch and control button.

[0044] It is not difficult to find that this embodiment is achieved by separately preparing the target acquisition component, namely the objective lens component (also called the aiming component), which is composed of the lens component and the movement component of the existing sight with thermal imaging and low-light-level night vision aiming functions (referred to as the fusion sight), and the eyepiece component containing the traditional LED graphic chip, the spectroscopic display component (mainly composed of a display screen and a spectroscope) and the lens, and realizing the transmission of image data through the added wireless communication module. At the same time, rails are provided outside their respective shells and are respectively connected to the rails provided on the pistol, so that the existing fusion sight can be conveniently applied to the pistol, which is not only convenient to use, but also flexible and simple to maintain and replace.

[0045] In the aforementioned system, namely the pistol fusion sight, the image from the camera assembly can be wirelessly transmitted to the AR glasses. Wearing the AR glasses, the user can observe the actual environment while also observing the image displayed by the camera assembly for aiming. Specifically, the pistol fusion sight also includes the AR glasses shown in Figure 8. A third wireless communication module connected to the AR display lens 26 is located within the mounting frame 25 of the AR glasses. This module transmits image data from the image sensor digital core to the AR display lens 26 for display within the display area 27 of the AR display lens 26. An aiming point 28 is located within the display area 27. By transmitting information captured by the camera assembly 2 in the pistol fusion sight to the AR glasses, the reduced field of view transmitted by the camera assembly 2 to the reflective sight 8, which results in a partial loss of visual field, can be effectively compensated. After the camera assembly 2 wirelessly transmits the image signal to the AR glasses, the display range of the AR glasses matches the field of view of the camera assembly 2, which is larger than the field of view of the reflective sight 8. This allows for a wider range of observation, facilitating target detection and identification. At the same time, an aiming cursor (i.e., aiming point 28 shown in FIG8 ) is added to the image displayed by the AR glasses. This aiming cursor can be moved within the image displayed by the AR glasses. Specifically, three buttons 29 located in the upper right corner of the AR glasses' mounting frame 25 are used to adjust the position of aiming point 28 within the display area frame 27. The position of this aiming cursor in the image captured by the camera assembly 2 mounted on the pistol can be calibrated with the pistol's aiming point, allowing aiming to be performed without the firearm's aiming baseline, using the positional relationship between the image transmitted by the camera assembly and the aiming cursor.

[0046] Finally, it should be noted that the image sensor digital core 12 involved in this embodiment can be any one of the current mainstream thermal imaging cores, night vision cores and visible light cores, or a fusion core of several cores. Common fusion cores currently include uncooled long-wave infrared (LWIR) OEM thermal imager modules. Model: Boson320, 4° (HFOV) 55mm or micro longwave infrared thermal imager module Model: Lepton 2.5, 80×60, 50°, radiometric function, with shutter.
