[0001] The invention relates to a reflective eyepiece and a digital sighting scope with the reflective eyepiece. Background Art

[0002] The eyepiece of an existing digital sight is usually a lens group, which magnifies the image on the screen through the lens to achieve the purpose of human vision.

[0003] The screen is typically an LED screen, which is inherently small and requires magnification through a lens assembly for the human eye to see. The lens assembly has a fixed exit pupil distance and a small exit pupil diameter. To ensure the image is visible, the user must place their eye at a certain distance from the eyepiece and within a certain range of the eyepiece axis. Beyond these two ranges, the image becomes difficult to see. Summary of the Invention

[0004] The purpose of the present invention is to overcome the problem of limited eyepiece field of view of digital sights in the prior art.

[0005] To achieve the above-mentioned object, the present invention provides a reflective eyepiece, comprising a base and an eyepiece mounting cover arranged at the rear end of the base;

[0006] An interface circuit board is provided at the front end of the base;

[0007] The eyepiece mounting cover is provided with a reflective lens located at the front end of the eyepiece mounting cover and a display screen located at the rear end bottom of the eyepiece mounting cover;

[0008] The display screen is electrically connected to a control button assembly provided on one side of the eyepiece mounting cover, and the control button assembly is electrically connected to the interface circuit board;

[0009] The rear end of the eyepiece mounting cover is provided with a protective glass.

[0010] A digital sight with a reflective eyepiece, comprising a digital movement assembly and an objective lens assembly mounted at the front end of the digital movement assembly, and also comprising the aforementioned reflective eyepiece;

[0011] The digital movement assembly is fixedly connected to the front top surface of the base;

[0012] The interface circuit board is connected to the circuit interface component at the bottom of the digital movement assembly;

[0013] The display screen projects the image collected by the objective lens assembly onto the reflective lens, and the image is projected out through the protective glass installed at the rear end of the eyepiece mounting cover.

[0014] As a further improvement, the digital movement assembly includes a shell and an image sensor digital movement arranged in the shell, and the image sensor digital movement is any one of a thermal imaging movement, a low-light movement and a white light movement.

[0015] As a further improvement, the digital sight further includes an infrared lighting module, a laser indication lighting module or a laser ranging module installed on the other side of the eyepiece mounting cover.

[0016] As a further improvement, the infrared lighting module, the laser indication lighting module or the laser ranging module is fixedly connected to the expansion slot cover plate arranged on the other side of the eyepiece mounting cover.

[0017] As a further improvement, a mouse tail wire switch is connected to the other side of the rear end of the base, and the control component of the mouse tail wire switch is provided with a magnification increase button and a magnification decrease button for respectively controlling the increase and decrease of the digital magnification of the digital movement component.

[0018] As a further improvement, a mouse tail wire switch is connected to the other side of the rear end of the base, and a magnification increase button and a magnification decrease button are provided on the control member of the mouse tail wire switch for respectively controlling the increase and decrease of the digital magnification of the digital movement assembly;

[0021] The bottom of the digital movement assembly is provided with a positioning groove corresponding to the positioning protrusion.

[0022] The advantages of the present invention are: using a reflective screen display method, the projected image is converted into parallel light. When the human eye observes, there is no exit pupil distance and exit pupil diameter, making observation faster and more convenient. And because the focus of the reflective display image is at infinity, the focus of the user's eyes is always at a distance when using it. There is no need to change the focal length when switching between viewing the screen and viewing the real scene. At a magnification of 1x, both eyes can observe the target at the same time, one eye observes through the sight eyepiece, and the other eye can directly observe the external surrounding environment at the same position as the camera image, making observation more comfortable. At the same time, the expansion can be connected to the infrared lighting module, laser indication lighting module or laser ranging module, further enriching the function of the sight and enhancing the practicality of the sight. The convenience of operation is also improved through the wire-controlled mouse tail switch. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] 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 examples.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] 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, rather than indicating or implying 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 limiting the present invention.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number 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 the present invention, unless otherwise specified, "plurality" means two or more.

[0038] In order to overcome the defects of existing digital sights, namely that the eyepiece is usually a lens group, the image on the screen is magnified by the lens to achieve the purpose of viewing by the human eye. The screen is usually an LED screen, which is relatively small in size. It needs to be magnified by the lens group so that the human eye can view it. The lens group has a fixed exit pupil distance and a small exit pupil diameter. When watching, the user needs to place the eyes at a certain distance from the eyepiece and within a certain range of the eyepiece axis to ensure that the image can be viewed. Outside these two ranges, the image is not easy to be viewed. This embodiment provides a digital sight with a reflective eyepiece as shown in Figure 1. On the basis of the existing digital movement assembly 1 and the objective lens assembly 2 installed at the front end of the digital movement assembly 1, a reflective eyepiece 3 as shown in Figure 1 is specially added. The reflective eyepiece 3 includes a base 4 shown in Figure 2 and an eyepiece arranged at the rear end of the base 4. Install the cover 5; the digital movement assembly 1 is fixedly connected to the front end top surface of the base 4; the specific connection method can be seen in Figure 7, where the front end top surface of the base 4 is provided with protrusions 17 respectively placed on the rear, left and right sides of the interface circuit board 6 (the right hand of the viewer is the front, the left hand is the rear, the upper side is the left, and the lower side is the right), and the bottom of the digital movement assembly 1 shown in Figure 7 is provided with a positioning groove 18 corresponding to the positioning protrusion 17. The assembly limit of the digital movement assembly 1 to the base 4 is achieved by the positioning protrusion 17 and the positioning groove 18, and then the fixation is completed by the screws at the four corners.

[0039] The interface circuit board 6 provided at the front end of the base 4 shown in Figure 2 is connected to the circuit interface part 7 at the bottom of the digital movement assembly 1 shown in Figure 4, thereby completing the connection between the reflective eyepiece 3 and the circuit and signal line of the digital movement assembly 1. The circuit and signal line are further electrically connected to the control button assembly 10 provided on one side of the eyepiece mounting cover 5 shown in Figure 1 or Figure 2. Specifically, the control button assembly 10 is electrically connected to the interface circuit board 6 to complete the connection between the circuit and the control line.

[0040] In order to overcome the aforementioned defects of the existing digital sights, the core of this embodiment is that a reflective lens 8 is provided at the front end of the eyepiece mounting cover 5 and a display screen 9 (i.e., a display) is provided at the bottom of the rear end of the eyepiece mounting cover 5. The display screen 9 is connected to a control button assembly 10 provided on one side of the eyepiece mounting cover 5. The control button assembly 10 can be used to adjust the size and resolution of the image - the same as the control buttons in the existing digital sights.

[0041] The display screen 9 projects the image captured by the objective lens assembly 2 onto the reflective lens 8, which then exits through the protective glass 11 mounted on the rear end of the eyepiece mounting cover 5. Since the emitted light is parallel, there is no pupil distance or diameter required for human observation, making observation faster and more convenient. Furthermore, since the focus of the reflective display image is at infinity, the user's eye remains focused at a distance during use. There is no need to switch focal lengths when switching between viewing the screen and the real scene. At a magnification of 1x, both eyes can simultaneously observe the target: one eye observes through the sight eyepiece, while the other eye directly observes the surrounding environment at the same location as the camera image, making observation more comfortable. This effectively overcomes the problem of limited eyepiece field of view present in existing digital sights.

[0042] Among them, the digital movement assembly 1 includes a shell as shown in Figure 3 and an image sensor digital movement 12 arranged in the shell, and the image sensor digital movement 12 is a fusion movement of any one or several of the thermal imaging movement, night vision movement and visible light movement (that is, ordinary camera movement, the corresponding product is "digital quick aiming"). A common fusion movement is Hikvision's RQ50L model, which uses 640x512 thermal + 2560x1440 cmos, and it can also use thermal imaging, low light or visible light separately, or it can simultaneously integrate and use thermal imaging, low light and visible light functions.

[0043] This embodiment, based on the previous embodiment, incorporates an infrared lighting module, a laser indicator lighting module 13, or a laser ranging module 14, as shown in FIG5 , on the other side of the eyepiece mounting cover 5, further enriching the functionality of the digital sight and enhancing its practicality. The infrared lighting module, laser indicator lighting module 13, or laser ranging module 14 is fixedly connected to the expansion slot cover 15, shown in FIG6 , located on the other side of the eyepiece mounting cover 5. It should be noted that the distance parameter information obtained by the laser ranging module 4 can be displayed on the display screen via a wired or wireless signal (Wi-Fi, Bluetooth). Specifically, the distance signal is transmitted to the image sensor digital core 12, which then transmits it to the display screen 9 for display.

[0044] This embodiment, building on the previous embodiment, features a mouse-tail wired switch 16 connected to the other side of the rear end of the base 4. The control element of this mouse-tail wired switch 16 is equipped with a magnification increase button and a magnification decrease button, respectively controlling the increase and decrease of the digital magnification of the digital movement assembly 1. The control element of this mouse-tail wired switch 16 also includes control buttons for the infrared lighting module, the laser indicator lighting module 13, or the laser rangefinder module 14. This mouse-tail wired switch effectively extends the operator's operating distance and greatly facilitates the convenience of key controls.
