DETAILED DESCRIPTION

[0033] In order to further explain 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 in conjunction with the accompanying drawings and embodiments.

[0034] The following will be combined with the 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it is necessary to understand that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "aligned", "overlap", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships 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 referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not 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 understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0037] The existing fusion sight (i.e., an internal red dot sight 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 parts, and the internal red dot sight is called the traditional part) has a large volume regardless of whether the new parts and the traditional parts are integrated with a common shell or separated by a circuit interface. When in use, they are presented as a whole state, and cannot be installed on firearms separately when in use. Therefore, the current fusion sight is not suitable for small-sized pistols, and still needs to be fixedly connected to each other, so the disassembly and assembly of the two parts is inconvenient. To overcome this defect, the present embodiment provides a Figure 1 The pistol fusion sight shown in the figure includes a split fusion sight (i.e., a split fusion sight similar to the split fusion sight recorded in the Chinese invention patent No. 202223132354.0) and an illumination module 1; wherein, the eyepiece assembly of the split fusion sight, i.e., the reflective sighting member 8 in this embodiment, is clamped at the top rear end of the pistol slide 6, and the aiming assembly of the split fusion sight, i.e., the camera assembly 2 in this embodiment, is arranged at the front bottom of the pistol grip 30, by Figure 1 It can be seen that the camera assembly 2 and the lighting module 1 are stacked up and down in the connection shell 3, that is, the two modules have a common shell, and the two modules are connected and assembled together for easy installation and carrying. Figure 3 As shown, it is basically the same as the existing lighting module, and is mainly composed of 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 the axial limitation of the camera assembly 2.

[0039] Figure 1 A second rail 16 is provided at the bottom of the reflective sight 8 of the split fusion sight shown in the figure, so as to fix the reflective sight 8 on the rear end top surface of the sliding sleeve 6 .

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

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

[0042] Since the camera assembly 2 and the imaging reflective sight 8 are divided into two parts and installed in the upper and lower parts of the firearm, there is a certain deviation in the coaxiality (upper and lower or left and right), which will cause the image and the actual object image to be out of coaxiality, resulting in misalignment, affecting observation and aiming. To overcome this defect, this embodiment solves this problem through two solutions. One is to Figure 5 The camera assembly 2 shown in the figure is equipped with an adjustment mechanism, so that the camera optical axis can be fine-tuned to a certain pitch and horizontal angle. In addition, the outer frame display area of ​​the screen inside the reflective aiming member 8 is reserved as the adjustment range for the fusion of the displayed image and the target image. Through the combination of these two methods, even if the installation causes the optical axis to be out of axiality, the user can achieve image fusion through adjustment, and achieve more accurate observation and aiming. The specific implementation diagram of this method Figure 5 As shown, a first adjusting screw 17 and a second adjusting screw 18 are respectively arranged on both sides of the top of the front end of the connecting shell 3; and an adjusting spring 19 (helical return spring) is arranged between the bottom of the chamber of the connecting shell 3 for mounting the camera assembly 2 and the bottom of the thermal imaging or low-light-level night vision lens assembly 13 of the camera assembly 2, so as to cooperate with the first adjusting screw 17 and the second adjusting 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 is fused with the actual image, refer to Figure 6 The auxiliary display frame of the display screen shown in the figure is provided with a maximum display area frame 22 of the screen, i.e., a rectangular frame 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 In this way, the position of the projected image can be adjusted to make it coincide with the actual image. When making a real object, the screen's largest display area frame 22 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 maximum display area frame of the screen ABCD The middle position of the screen display area adjustment frame 23 rectangular frame abcd Indicates that the display area is adjusted to the maximum display area of ​​the screen 22 rectangular frame ABCDTherefore, 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 efgh The 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 Internal up / down / left / right adjustment.

[0043] Depend on Figure 1 , 4 It can be seen that a power switch 9 is arranged on one side of the connecting shell 3, and a control button 10 and a charging interface 11 are arranged 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 in this embodiment, 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 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 are separately prepared, and the image data is transmitted through the added wireless communication module. At the same time, rails are arranged outside their respective shells and are respectively connected to the rails arranged 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, i.e., the pistol fusion sight, the image of the camera assembly can be wirelessly transmitted to the AR glasses, and the user wearing the AR glasses can observe the display image of the camera assembly while observing the actual environment to aim. Figure 8 The AR glasses shown in the figure have a third wireless communication module connected to an AR display lens 26 disposed in the mounting frame 25 of the AR glasses, for transmitting image data from the image sensor digital movement to the AR display lens 26 for display in the display area frame 27 of the AR display lens 26; an aiming point 28 is disposed in the display area frame 27. By transmitting the information collected in the camera component 2 in the pistol fusion sight to the AR glasses, the defect of a reduced field of view transmitted by the camera component 2 to the reflective aiming piece 8, resulting in a partial loss of field of view, can be effectively compensated. After the camera component 2 wirelessly transmits the image signal to the AR glasses, the display range of the AR glasses is consistent with the field of view angle of the camera component 2, which is larger than the field of view angle of the reflective aiming piece 8, so that a larger range can be observed, which is beneficial to the discovery and identification of the target. At the same time, an aiming cursor (i.e. Figure 8The aiming cursor 28 shown in the figure can be moved in the display image of the AR glasses, specifically, the three buttons 29 set in the upper right corner of the mounting frame 25 of the AR glasses are used to adjust the position of the aiming point 28 in the display area frame 27. The position of the aiming cursor in the picture taken by the camera assembly 2 installed on the pistol can be calibrated with the aiming point of the pistol, so as to achieve the separation from the aiming baseline of the firearm, and aiming can be performed through the position relationship between the image transmitted by the camera assembly and the aiming cursor.

[0046] Finally, it should be noted that the image sensor digital movement 12 involved in this embodiment can be any one of the current mainstream thermal imaging movements, night vision movements and visible light movements, or a fusion movement of several movements. Currently common fusion movements include uncooled long-wave infrared (LWIR) OEM thermal imager modules.
