Description

Technical Field

[0001] This invention relates to the field of aiming scope technology, and in particular to a holographic aiming scope. Background Technology

[0002] Existing holographic sights use a mil-position adjustment mechanism for the lens, which is typically mounted inside the sight housing via a base. The base has pitch and lateral adjustment mechanisms, and the base and sight housing are connected by a guide post and spring, with positioning via a lead screw and nut in the pitch adjustment mechanism. However, the lead screw and nut can shift during movement, affecting aiming accuracy. Furthermore, the floating connection between the base and the sight housing makes assembly difficult and inefficient. In order to project the virtual image to infinity, traditional holographic sights are usually designed with multiple mirrors to reflect the light source multiple times, extending the optical path and focal length. However, this method requires multiple mirrors to be installed in multiple locations within the sight housing to achieve this multiple reflections and extend the optical path, thus limiting the size of the sight housing, as shown in patent document CN215676674U. This invention integrates the lens onto a combined container with a ball-head connector. A corresponding ball-and-socket joint is provided in the mounting cavity of the sight housing to connect to the combined container, achieving automatic centering after assembly and reducing assembly difficulty. Furthermore, by setting up a prism, the prism, light source, and reflector are installed at the same height. Through multiple reflections within the prism, only one reflector is needed. The light is reflected by the reflector to the filter, and then reflected to the direction of human eye observation. Compared to the original two reflectors, which require three layers of light path (upper, middle, and lower) to finally reflect to the human eye, this invention only requires two layers of light path. Therefore, by using the optical module of this invention, the mirror housing can be designed to be shorter and the structure more compact. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this invention is to provide a holographic sight.

[0004] This invention employs the following method: A holographic sight includes a scope housing, a light source, a control circuit board, and a power supply. The power supply, control circuit board, and light source are electrically connected. The scope housing has a mounting cavity containing a combined container. A prism and the light source are mounted on the combined container. A ball-head connector is provided on the outer periphery of the combined container. A ball-and-socket joint adapted to the ball-and-socket connector is provided in the mounting cavity. The ball-and-socket connector and the ball-and-socket joint form a spherical kinematic pair after assembly. A mil-adjustment assembly is provided on the scope housing, avoiding the ball-and-socket joint, to drive the combined container to rotate around the spherical kinematic pair to adjust the mil. A reflector is mounted in the mounting cavity at the same height as the combined container. The light source is incident on the prism and reflected multiple times before exiting, and then incident on the reflector along the original emission direction of the light source. A filter is also mounted on the scope housing, with the filter's reflection direction opposite to that of the reflector. The light source is reflected by the reflector to the filter, and then reflected by the filter to the direction of human eye observation.

The ball head connector on the left side is adapted to the ball socket on the left side wall, and the ball head connector on the right side is adapted to the ball socket on the right side wall.

[0009] Preferably, the combined container has an annular frame for mounting the lens on the side near the reflector, the ball head connector is located on the side of the annular frame, and the light source is fixedly mounted on the side of the combined container away from the reflector.

[0010] Preferably, the position adjustment assembly includes a left-right adjustment mechanism and a pitch adjustment mechanism; the pitch adjustment mechanism is mounted on the mirror housing and abuts against the upper and lower surfaces of the combined container; the left-right adjustment mechanism is mounted on the mirror housing and abuts against the side of the combined container.

[0011] Preferably, the left-right adjustment mechanism includes a left-right adjustment screw and a first return spring, and the pitch adjustment mechanism includes a pitch adjustment screw and a second return spring. Both the first and second return springs are installed in the mounting cavity. The first return spring is located on one side of the combined container, and the left-right adjustment screw is installed on the side of the mirror housing and passes through the mounting cavity to abut against the other side of the combined container. The second return spring is located between the lower surface of the combined container and the bottom surface of the mounting cavity, and the pitch adjustment screw is installed on the upper surface of the mirror housing and passes through the mounting cavity to abut against the upper surface of the combined container.

[0012] Preferably, the left and right adjustment screw is provided with a left and right adjustment slider, which abuts against the left or right side of the combined container away from the reflector; the pitch adjustment screw is provided with a pitch adjustment slider, which abuts against the upper surface of the combined container away from the reflector.

[0013] Preferably, a left-right adjusting nut is fitted onto the left-right adjusting screw, and a pitch adjusting nut is fitted onto the pitch adjusting screw; the left-right adjusting nut and the pitch adjusting nut are exposed outside the mirror housing; the left-right adjusting screw and the pitch adjusting screw are provided with limiting grooves; a retaining spring is inserted into the mirror housing at a position opposite to the limiting grooves of the left-right adjusting screw and the pitch adjusting screw, so as to prevent the pitch adjusting screw and the left-right adjusting screw from detaching from the mirror housing.

[0014] Preferably, a third return spring is provided on the mirror housing at a position opposite to the screw heads of the pitch adjustment screw and the left and right adjustment screw. A ball is connected to the end of the third return spring facing the screw head, and an annular wave-shaped tooth is provided on the end face of the screw head facing the third return spring. A screw sealing ring is provided on both the pitch adjustment screw and the left and right adjustment screw, and a nut sealing ring is provided on both the left and right adjustment nut and the pitch adjustment nut.

[0015] Preferably, the lower side of the lens housing is provided with a bottom cover, and the bottom cover is provided with a quick-release mechanism for fixing the lens housing to the guide rail of the firearm; the control circuit board is fixed on the lower surface of the combined container.

[0016] The beneficial effects of this invention are as follows: This invention provides a holographic sight, which, compared with the prior art, has at least the following technical effects: 1. By setting a spherical motion pair formed by the ball joint and the ball socket, the traditional floating connection between the base and the scope housing is replaced, enabling automatic centering during assembly, greatly reducing assembly difficulty and improving assembly efficiency; at the same time, by using a single reflector in conjunction with multiple reflections of the prism, only two layers of optical path are needed to achieve a virtual image at infinity, which effectively reduces the size of the scope housing and makes the structure more compact compared to the traditional three-layer optical path design with multiple reflectors; the mil-position adjustment component drives the combined container to rotate around the spherical motion pair, making the mil-position adjustment more precise and improving aiming accuracy.

[0017] 2. If a triangular prism is used, the two prisms are separated by a gap, which can extend the light path and achieve a longer focal length in a limited space, thus improving the image quality of the lens. Triangular or pentagonal prisms can also be used, with the same goal of extending the light path in a limited space.

[0018] 3. Multiple lenses are installed side-by-side at intervals on the combined container. Light emitted from the prism passes through these lenses in sequence before entering the reflector. The lenses can refract and correct the light, which helps to optimize the optical path, improve image quality, and make the virtual image of the target clearer and more stable. The lenses, prisms, light source, and control circuit board are all installed on the combined container to form an independent optical imaging module, which is compatible with different aiming scope housings (only the same mounting cavity needs to be processed in the scope housing, and the rest of the shape can be changed arbitrarily, which helps to reduce production costs). It can realize the fusion of virtual and real AR scenes.

[0019] 4. The ball joint is symmetrically located on the left and right sides of the combined container, and the ball socket is symmetrically located on the left and right side walls of the mounting cavity. This symmetrical arrangement allows the combined container to be subjected to more balanced forces in the mounting cavity of the mirror housing. When adjusting the position, the combined container rotates more smoothly around the spherical kinematic pair, further ensuring the accuracy and stability of the adjustment.

[0020] 5. The left-right adjustment mechanism and the pitch adjustment mechanism act on the side and upper and lower surfaces of the combined container respectively, and can independently realize the mil adjustment in the left-right and pitch directions. Combined with the cooperation of the screw and spring, the adjustment is flexible and can adapt to the ballistic correction needs in different shooting scenarios, thereby improving the hit rate.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Please see Figures 1 to 13A holographic sight includes a scope housing 1, a light source 2, a control circuit board 3, and a power supply 4. The power supply 4 is electrically connected to the control circuit board 3 and the light source 2. The scope housing 1 has a mounting cavity 11, and a combined container 5 is provided in the mounting cavity 11. A prism 6 and the light source 2 are mounted on the combined container 5. A ball joint 51 is provided on the outer peripheral surface of the combined container 5. A ball socket 12 adapted to the ball joint 51 is provided in the mounting cavity 11. After the ball joint 51 and the ball socket 12 are assembled, a spherical kinematic pair is formed. The scope housing 1 avoids the ball socket 12. A positioning adjustment component 7 is provided to drive the combined container 5 to rotate around the spherical kinematic pair to adjust the positioning. A reflector 8 is installed in the mounting cavity 11. The reflector 8 and the combined container 5 are installed at the same height. The light source 2 is incident on the prism 6, and after multiple reflections in it, it is emitted and incident on the reflector 8 along the original emission direction of the light source 2. A filter 9 is also installed on the mirror housing 1. The reflection direction of the filter 9 is opposite to that of the reflector 8. The light source 2 is reflected by the reflector 8 to the filter 9, and then reflected by the filter 9 to the direction of human eye observation. By setting a spherical kinematic pair formed by the ball joint 51 and the ball socket 12, the traditional floating connection between the base and the mirror housing 1 is replaced. This allows for automatic centering during assembly, significantly reducing assembly difficulty and improving efficiency. Simultaneously, the use of a single reflector 8 in conjunction with multiple reflections by the prism 6 allows for a virtual image to be projected at infinity with only two optical paths. Compared to the traditional three-layer optical path design with multiple reflectors 8, this effectively reduces the volume of the mirror housing 1, making the structure more compact. The mil-position adjustment component 7 drives the combined container 5 to rotate around the spherical kinematic pair, making the mil-position adjustment more precise and improving aiming accuracy. Preferably, the light source 2 can be an ultra-high brightness LED screen, supporting monochrome or color display. The brightness and color can be dynamically adjusted via the control circuit board 3 to adapt to different lighting environments such as daytime and night vision. The filter 9 can be a holographic diffraction filter to enhance the fusion effect between the virtual image and the target.

[0041] Please see Figures 1 to 13 Preferably, the prism 6 is a pentaprism; or, the prism 6 is a triangular prism, with multiple triangular prisms installed side-by-side at intervals on the combined container 5, and a gap between adjacent triangular prisms (G in the attached figure indicates the gap). A preferred embodiment uses two triangular prisms, namely prism one 61 and prism two 62, separated by a gap. This allows for extending the optical path within a limited space, and a longer focal length improves the imaging quality of the lens 10. The prism 6 can also be a triangular prism or a pentagonal prism, with the same purpose of extending the optical path within a limited space. The optical path is extended through multiple reflections within the prism 6, and the focal length is extended, ensuring that the virtual image is presented at infinity without parallax.

[0042] Please see Figures 1 to 8Preferably, the combined container 5 is further equipped with multiple lenses 10, which are arranged side by side at intervals. Light emitted from the prism 6 passes through the multiple lenses 10 in sequence before entering the reflecting mirror 8. The multiple lenses 10 arranged side by side at intervals on the combined container 5 allow light emitted from the prism 6 to pass through these lenses 10 in sequence before entering the reflecting mirror 8. The lenses 10 can refract and correct the light, helping to optimize the optical path, improve imaging quality, and make the virtual image of the target clearer and more stable.

[0043] Please see Figures 1 to 8 Preferably, there are three lenses 10, each with a different refractive index: lens one 101, lens two 102, and lens three 103. The combination of lenses 10 with different refractive indices can specifically compensate for the refractive differences of different wavelengths of light, effectively eliminating chromatic aberration and ensuring that the aiming points of different colors of light are consistent. In practical applications, the number of lenses 10 can be two, three, four, five, etc., as needed, and is not limited to this. In practical applications, the refractive index parameters of the lenses 10 can be selected according to the dominant wavelength of the light source 2 (such as red light or green light) to achieve precise chromatic aberration compensation. Lens 10 can also be a cemented doublet lens 10, an aspherical surface, or a freeform surface.

[0044] Please see Figures 1 to 8 Preferably, the ball joint 51 is symmetrically arranged on the left and right sides of the combined container 5, and the ball socket 12 is symmetrically arranged on the left and right side walls of the mounting cavity 11. The ball joint 51 on the left side is adapted to the ball socket 12 on the left side wall, and the ball joint 51 on the right side is adapted to the ball socket 12 on the right side wall. The symmetrical spherical kinematic pair makes the combined container 5 rotate more smoothly, the force is evenly distributed during adjustment, mechanical wear is reduced, and service life is extended. The surfaces of the ball head and ball socket 12 can be smoothed or coated with lubricant to reduce rotational friction and make the tight-fitting adjustment smoother.

[0045] Please see Figures 1 to 8 Preferably, the combined container 5 has an annular frame 52 on the side near the reflector 8 for mounting the lens 10, and the ball joint 51 is located on the side of the annular frame 52. The light source 2 is fixedly mounted on the side of the combined container 5 away from the reflector 8. The annular frame 52 facilitates the positioning and installation of the lens 10, and the layout of the ball joint 51 and optical components is reasonable, saving space in the combined container 5 and achieving a compact structure. The annular frame 52 can be integrally formed with the combined container 5, improving structural strength and ensuring the coaxiality of the lens 10 and the optical path. The lens 10, prism 6, and light source 2 are all mounted on the combined container 5 to form an independent optical imaging module, compatible with different aiming scope housings 1 (only the same mounting cavity 11 needs to be machined in the scope housing 1, and the rest of the shape can be arbitrarily changed, which helps to reduce production costs), enabling the realization of virtual and real-world AR fusion scenes.

[0046] Please see Figure 1 , Figure 2 , Figures 9 to 11 Preferably, the mil adjustment component 7 includes a left-right adjustment mechanism 71 and a pitch adjustment mechanism 72; the pitch adjustment mechanism 72 is mounted on the mirror housing 1 and abuts against the upper and lower surfaces of the combined container 5; the left-right adjustment mechanism 71 is mounted on the mirror housing 1 and abuts against the side of the combined container 5. The mils in the left-right and pitch directions can be adjusted independently to meet ballistic correction requirements, and the operation is intuitive and convenient.

[0047] Please see Figure 1 , Figure 2 , Figures 9 to 11 Preferably, the left-right adjustment mechanism 71 includes a left-right adjustment screw 711 and a first return spring 712, and the pitch adjustment mechanism 72 includes a pitch adjustment screw 721 and a second return spring 722. Both the first return spring 712 and the second return spring 722 are installed in the mounting cavity 11. The first return spring 712 is located on one side of the combined container 5, and the left-right adjustment screw is installed on the side of the mirror housing 1 and passes through the mounting cavity 11 to abut against the other side of the combined container 5. The second return spring 722 is located between the lower surface of the combined container 5 and the bottom surface of the mounting cavity, and the pitch adjustment screw 721 is installed on the upper surface of the mirror housing 1 and passes through the mounting cavity 11 to abut against the upper surface of the combined container 5. The screw drive, combined with the spring return, achieves precise adjustment of the position while eliminating adjustment gaps, ensuring the stable position of the combined container 5 and preventing it from being affected by vibration. The spring constant can be selected according to the adjustment force requirements to ensure moderate feel and reliable return during adjustment.

[0048] Please see Figure 1 , Figure 2 , Figures 9 to 11 Preferably, a left-right adjusting slider 713 is threaded through the left-right adjusting screw 711, and the left-right adjusting slider 713 abuts against the left or right side of the combined container 5 away from the reflector 8; a pitch adjusting slider 723 is threaded through the pitch adjusting screw 721, and the pitch adjusting slider 723 abuts against the upper surface of the combined container 5 on the side away from the reflector 8. The contact surfaces of the left-right adjusting slider 713 and the pitch adjusting slider 723 with the combined container 5 are arc surfaces, which can reduce friction and extend service life. The left-right adjusting slider 713 and the pitch adjusting slider 723 abut against the tail of the combined container 5, that is, the side away from the reflector 8, and do not contact the prism 6, the light source 2, the control circuit board 3, etc.

[0049] Please see Figure 1 , Figure 2 , Figures 9 to 11 Preferably, a left-right adjusting nut 714 is fitted onto the left-right adjusting screw 711, and a pitch adjusting nut 724 is fitted onto the pitch adjusting screw 721. The left-right adjusting nut 714 and the pitch adjusting nut 724 are exposed outside the mirror housing 1. The left-right adjusting screw 711 and the pitch adjusting screw 721 are provided with limiting grooves. A retaining spring 73 is inserted into the mirror housing 1 at a position opposite to the limiting grooves of the left-right adjusting screw 711 and the pitch adjusting screw 721, thus preventing the pitch adjusting screw 721 and the left-right adjusting screw 711 from detaching from the mirror housing 1. The adjusting nuts facilitate user operation, and the retaining spring 73 cooperates with the limiting grooves to prevent the screws from falling off, ensuring the reliability and safety of the adjustment mechanism. The surface of the nuts can be provided with anti-slip textures for easy gripping and adjustment, and the retaining spring 73 is made of elastic metal material to ensure secure positioning.

[0050] Please see Figure 1 , Figure 2 , Figures 9 to 11 Preferably, a third return spring 74 is provided on the lens housing 1 at a position opposite to the screw heads of the pitch adjustment screw 721 and the left / right adjustment screw 711. A ball bearing 75 is connected to the end of the third return spring 74 facing the screw head, and the end face of the screw head facing the third return spring has annular wave-shaped teeth. Screw sealing rings 77 are provided on both the pitch adjustment screw 721 and the left / right adjustment screw 711, and nut sealing rings 76 are provided on both the left / right adjustment nut 714 and the pitch adjustment nut 724. The ball bearing 75, in conjunction with the wave-shaped teeth, generates an adjustment feel, facilitating precise control of the micrometer adjustment amount. The sealing rings enhance the sealing of the lens housing 1, preventing dust and moisture from entering and affecting optical performance and circuit operation. The spacing of the wave-shaped teeth can be designed according to the adjustment accuracy requirements, such as each setting corresponding to an adjustment amount of 0.1 micrometers.

[0051] Please see Figure 1 , Figure 2 , Figure 12 , Figure 13 Preferably, the lower side of the lens housing 1 is provided with a bottom cover 13, and the bottom cover 13 is provided with a quick-release mechanism 14 for fixing the lens housing 1 to the guide rail of the firearm; the lower surface of the combined container 5 is fixed with the control circuit board 3. The control circuit board 3 can integrate sensor interfaces such as gyroscopes and rangefinders to realize functions such as automatic ballistic correction. The control circuit board 3 is directly integrated into the combined container 5, which has high integration, is convenient for assembly, and also facilitates quick disassembly; the structure of the quick-release mechanism 14 can be found in the patent document with publication number CN214666371U, and will not be described in detail here.

[0052] The present invention has the following working principle:

[0053] Power supply 4 supplies power to light source 2, control circuit board 3, and integrated sensors (such as rangefinders and gyroscopes). Control circuit board 3 controls light source 2 to emit light. The reticle image and display information (such as target distance and ballistic correction parameters) emitted by light source 2 are incident on prism 6 on the combined container 5. Taking two triangular prisms 6 as an example: the LED display content is incident horizontally through prism two 62 in direction A, undergoes total internal reflection through path B and path C to prism one 61, then undergoes total internal reflection through path D and path E, and undergoes horizontal total internal reflection through path F to lens three 103, lens two 102, and lens one 101. After being formed into parallel light by the three sets of lenses 10, it is incident on reflector 8, then reflected by reflector 8 at approximately 45° to filter 9, and then reflected by filter 9 at approximately 45° to the direction of human eye observation. The human eye receives the image information and forms a virtual image at infinity in front of it (see...). Figure 5 , Figure 6 Prism 62 and prism 61 are combined to form a double prism 6, with an air gap between them. The gap between the two prisms 6 allows for a longer light path and focal length within a limited space, improving the imaging quality of lens 10. (The double prism 6, combined with three lenses 10 of different refractive indices, shortens the total light path length through the light deflection / folding function of the double prism 6. Simultaneously, the complementary dispersion characteristics of the three lenses achieve a balance between "compact structure" and "high-definition imaging.") 1. The light path compression effect of the double prism: It can fold the originally straight-propagating light path (such as the long light path in projection and telescopes) by 90° or 180°, reducing the equipment size like a "folded straw." A pentagonal prism can also be used for the double prism 6; the purpose is the same: to extend the light path within a limited space. The three sets of lenses 10 (lens 101, 102, and 103) are used to correct the magnification and image quality of the LED, as well as to compensate for chromatic aberration. Lenses 10 with different refractive indices have different refractive capabilities for different wavelengths of light. Therefore, by combining lenses 10 with different refractive indices, precise control of different wavelengths of light can be achieved, thereby achieving the purpose of chromatic aberration compensation. (Chromatic aberration correction and imaging optimization of the three sets of lenses: The three sets of lenses with different refractive indices (corresponding to different Abbe numbers) can, on the one hand, correct the additional chromatic aberration caused by the double prism, and on the other hand, can synergistically optimize the axial / lateral chromatic aberration of the main image. At the same time, by adjusting the focal length and magnification through lens combination, high-definition image quality is maintained even after compressing the optical path.)

[0054] When precise adjustment is required, the adjusting nut on the outside of the mirror housing 1 is operated: For left and right adjustment, rotating the left and right adjusting nut 714 rotates the left and right adjusting screw 711, which pushes the left and right adjusting slider 713 to move and push the combined container 5 (specifically, the left side), causing the combined container 5 to swing to the right around the spherical motion pair to adjust the angle of the light source 2 entering the reflector 8; when rotating the left and right adjusting screw 711 in the opposite direction, the left and right adjusting slider 713 no longer pushes the combined container 5, and the first return spring 712 provides a reverse force to push the combined container 5 to the left around the spherical motion pair. At the same time, the engagement of the ball bearing 75 and the wave-shaped teeth creates a sense of position, ensuring precise adjustment; the same applies to pitch adjustment. Rotating the pitch adjusting nut 724 drives the combined container 5 to pitch up and down through the pitch adjusting screw 721 and the slider, and the second return spring 722 pushes it back to its original position. During the adjustment process, the retaining ring 73 prevents the screw from disengaging from the mirror housing 1, and the sealing ring prevents external debris from entering.

[0055] Meanwhile, the control circuit board 3 processes sensor data in real time, dynamically adjusts the brightness and color of the reticle through the LED light source 2 (such as switching night vision mode), and overlays ballistic correction information onto the virtual image; if equipped with network functionality, the data can be synchronized to the command system to achieve AR-fused aiming scenarios. The quick-release mechanism 14 of the bottom cover 13 facilitates the quick fixing of the scope to the gun rail (such as a Picatinny rail) to meet the needs of actual combat.
