For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0058] The preferred embodiments of this application will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain this application, and are not used to limit this application.

[0059] As Figures 1 to 3 shown, according to an embodiment of this application, an off-axis optical sight is provided, including: a housing 11, an adjustment mechanism 13, a compensation frame 14, and a first reflector 15; an optical component 12 is provided on the housing 11; the adjustment mechanism 13 is provided inside the housing 11, and the adjustment mechanism 13 includes a ballistic adjustment mechanism 131 and a windage adjustment mechanism 132; the compensation frame 14 is rotatably provided inside the housing 11, and the ballistic adjustment mechanism 131 drives the compensation frame 14 to rotate relative to the optical component 12; the first reflector 15 is rotatably connected to the compensation frame 14, and the windage adjustment mechanism 132 drives the first reflector 15 to rotate relative to the compensation frame 14.

[0060] The off-axis optical sight provided by the embodiment of this application includes a housing 11, an adjustment mechanism 13, a compensation frame 14, and a first reflector 15; the compensation frame 14 is rotatably provided inside the housing 11, and the first reflector 15 is rotatably provided on the compensation frame 14. The ballistic adjustment mechanism 131 is used to adjust the compensation frame 14 to make the compensation frame 14 rotate relative to the optical component 12; the windage adjustment mechanism 132 is used to adjust the first reflector 15 to make the first reflector 15 rotate relative to the compensation frame 14. Furthermore, through the cooperation of the ballistic adjustment mechanism 131 and the windage adjustment mechanism 132, the first reflector 15 is adjusted at multiple angles, so that the position of the first reflector 15 changes. The optical sight forms an image through the cooperation of the first reflector 15 and the optical component 12. By adjusting the position of the first reflector 15 through the ballistic adjustment mechanism 131 and the windage adjustment mechanism 132, the position of the aiming point observed by the human eye 25 through the optical sight changes. Furthermore, through the change in the position of the aiming point, the functions of adjusting the ballistic position and the windage position are realized.

[0061] Furthermore, one end of the first reflector 15 is rotatably connected to the compensation frame 14 through a first pin shaft. The first pin shaft serves as the rotation axis of the first reflector 15, so that the first reflector 15 rotates relative to the compensation frame 14 under the drive of the windage adjustment mechanism 132.

[0062] It can be understood that the optical component 12 includes a light source 121. After the first light beam emitted by the light source 121 is shaped by the optical component 12, a collimated aiming reticle virtual image is formed. By making the aiming reticle virtual image coincide with the incident light from the target 24, that is, by aligning the reticle image with the target 24, the aiming function of the off-axis optical sight is realized.

[0063] In some examples, the ballistic adjustment mechanism 131 is used to adjust the vertical deviation between the aiming reticle virtual image and the incident light of the target 24, and the windage adjustment mechanism 132 is used to adjust the horizontal deviation between the aiming reticle virtual image and the incident light of the target 24, so as to realize the up, down, left and right adjustment of the aiming point position, that is, to adjust the ballistic position and the windage position. It should be noted that the vertical adjustment of the ballistic position is also called the ballistic position adjustment, and the horizontal adjustment of the ballistic position is also called the windage position adjustment.

[0064] Furthermore, the first reflector 15 includes a reflector base plate and a reflector body. The reflector base plate is rotatably connected to the compensation frame 14, and the reflector body is fixedly adhered to the reflector base plate to ensure that there is no obstruction on the surface of the reflector body and to ensure the imaging quality.

[0065] As Figures 1 to 5 shown, in a feasible implementation manner, the ballistic adjustment mechanism 131 includes: a ballistic adjustment lead screw 1311, a ballistic adjustment block 1312, a first clearance eliminating member 1313, and a guide groove 1314; the ballistic adjustment lead screw 1311 is rotatably connected to the housing 11, the first end of the ballistic adjustment lead screw 1311 protrudes outside the housing 11, and a first adjustment portion is provided on the first end of the ballistic adjustment lead screw 1311 to drive the ballistic adjustment lead screw 1311 to rotate relative to the housing 11 by adjusting the first adjustment portion; the ballistic adjustment block 1312 is sleeved outside the ballistic adjustment lead screw 1311, the ballistic adjustment block 1312 is in threaded cooperation with the ballistic adjustment lead screw 1311, the ballistic adjustment block 1312 is in contact with the compensation frame 14, and the compensation frame 14 is driven to rotate relative to the optical component 12 by the axial movement of the ballistic adjustment block 1312 along the ballistic adjustment lead screw 1311; the first clearance eliminating member 1313 is provided on the ballistic adjustment lead screw 1311, the first clearance eliminating member 1313 is located on both sides of the ballistic adjustment lead screw 1311, the first end of the first clearance eliminating member 1313 is in contact with the housing 11, and the second end of the first clearance eliminating member 1313 is in contact with the ballistic adjustment block 1312; the guide groove 1314 is provided on the inner wall of the housing 11, and the ballistic adjustment block 1312 moves in the guide groove 1314.

[0066] In this technical solution, the ballistic adjustment lead screw 1311 is rotatably connected within the housing 11. A first adjustment portion is provided at one end of the ballistic adjustment lead screw 1311 that protrudes from the housing 11. By manipulating the first adjustment portion, the ballistic adjustment lead screw 1311 rotates relative to the housing 11, causing the ballistic adjustment block 1312 threadedly connected to the ballistic adjustment lead screw 1311 to move axially along the ballistic adjustment lead screw 1311. Consequently, the ballistic adjustment block 1312 pushes the compensation spectacle frame 14 to rotate, changing the positions of the compensation spectacle frame 14 and the first reflector 15 relative to the optical assembly 12, causing the position of the aiming point to change, and thus achieving the adjustment of the ballistic position. By providing first clearance elimination members 1313 on both sides of the ballistic adjustment block 1312, a pressing force is provided for the ballistic adjustment block 1312 on both sides to eliminate the threaded transmission clearance between the ballistic adjustment lead screw 1311 and the ballistic adjustment block 1312, ensuring the accuracy of the movement of the ballistic adjustment block 1312, and thereby improving the accuracy of the adjustment of the ballistic adjustment block 1312 to the compensation spectacle frame 14. By providing a guide groove 1314 on the housing 11 to guide the movement of the ballistic adjustment block 1312 and restricting the degree of freedom of rotation of the ballistic adjustment block 1312, it is ensured that when the ballistic adjustment lead screw 1311 makes a rotational movement, the ballistic adjustment block 1312 only moves axially along the ballistic adjustment lead screw 1311, further improving the accuracy of the movement of the ballistic adjustment block 1312, and thereby further improving the accuracy of the adjustment of the ballistic adjustment block 1312 to the compensation spectacle frame 14 and improving the accuracy of ballistic adjustment.

[0067] In this technical solution, since the aiming position observed by the human eye 25 ultimately needs to be reflected by the first reflector 15 and enter the human eye 25, when the compensation spectacle frame 14 rotates and drives the first reflector 15 to rotate, the aiming position observed by the human eye 25 changes in the vertical direction, thereby achieving the adjustment of the vertical position of the ballistic.

[0068] It can be understood that for each full rotation of the ballistic adjustment lead screw 1311, the ballistic adjustment block 1312 moves a distance equal to one pitch.

[0069] Furthermore, as Figure 3 shown in, a first support portion is provided on the housing 11, a first sliding groove is provided on the first adjustment portion, the first support portion is connected to the housing 11 through an elastic member, and the first support portion is attached to and embedded in the first sliding groove to slidably or rollably support the first adjustment portion through the first support portion, ensuring the stability of the rotation of the first adjustment portion and the first lead screw. As a preferred solution, balls are provided on the first support portion, and the balls roll in the first sliding groove to rollably support the first adjustment portion through the balls, improving the flexibility of the rotation of the first adjustment portion and the first lead screw.

[0070] In some examples, the first adjustment part can adopt a knob structure, or a paddle structure, etc. As long as it is ensured that when the first adjustment part is manipulated, the ballistic adjustment lead screw 1311 can rotate synchronously with the first adjustment part in a timely manner.

[0071] As Figure 3 shown, in a feasible implementation, a first inclined surface 20 is provided on the bottom surface of the ballistic adjustment block 1312, and a second inclined surface 21 is provided on the compensation spectacle frame 14. The second inclined surface 21 fits with the first inclined surface 20 to drive the compensation spectacle frame 14 to rotate by moving the ballistic adjustment block 1312.

[0072] In this technical solution, when the ballistic adjustment block 1312 moves along the axial direction of the ballistic adjustment lead screw 1311, the contact position between the downwardly provided first inclined surface 20 on the ballistic adjustment block 1312 and the upwardly provided second inclined surface 21 on the compensation spectacle frame 14 changes, and the pressure of the first inclined surface 20 on the second inclined surface 21 changes. Thereby driving the compensation spectacle frame 14 to flip up or down around its own rotation axis, and at the same time the first reflector 15 flips up or down synchronously with the compensation spectacle frame 14 to adjust the height position of the first reflector 15.

[0073] Furthermore, the slopes of the first inclined surface 20 and the second inclined surface 21 match to ensure full contact when the first inclined surface 20 and the second inclined surface 21 slide relative to each other.

[0074] In some examples, as Figure 4 shown, when the ballistic adjustment lead screw 1311 drives the ballistic adjustment block 1312 to move away from the first adjustment part, the ballistic adjustment block 1312 climbs along the first inclined surface 20, increasing the contact pressure between the compensation spectacle frame 14 and the ballistic adjustment block 1312. Under the pressure of the ballistic adjustment block 1312, the compensation spectacle frame 14 rotates clockwise around its own rotation axis, and the position of the first reflector 15 is lowered.

[0075] As Figure 1 and Figure 3 shown, in a feasible implementation, the off-axis optical sight further includes: a first reset elastic member 16 and a positioning rod 17; the first reset elastic member 16 is vertically arranged below the compensation spectacle frame 14, the first end of the first reset elastic member 16 is arranged on the inner wall of the housing 11, and the second end of the first reset elastic member 16 is arranged on the compensation spectacle frame 14; the positioning rod 17 is vertically arranged on the inner wall of the housing 11, and the positioning rod 17 passes through the first reset elastic member 16.

[0076] In this technical solution, the first reset elastic member 16 is arranged between the compensation lens frame 14 and the housing 11. The first reset elastic member 16 elastically supports the first emission mirror frame below the compensation lens frame 14 to ensure that the first reflector 15 frame can always be in contact with the ballistic adjustment block 1312, guarantee the accuracy of the adjustment of the ballistic adjustment block 1312 to the first reflector 15 frame, and at the same time help the first reflector 15 frame to quickly reset. The positioning rod 17 is fixed on the inner wall of the housing 11, and the first reset elastic member 16 is sleeved on the positioning rod 17. The positioning rod 17 supports and guides the first reset elastic member 16.

[0077] Furthermore, the first reset elastic member 16 is arranged directly below the second inclined surface 21.

[0078] In some examples, such as Figure 4 As shown, when the ballistic adjustment lead screw 1311 drives the ballistic adjustment block 1312 to move in the direction close to the first adjustment part, the ballistic adjustment block 1312 climbs and descends along the first inclined surface 20, reducing the contact pressure between the compensation lens frame 14 and the ballistic adjustment block 1312. Under the elastic force of the first reset elastic member 16, the compensation lens frame 14 rotates counterclockwise around its own rotation axis, and the position of the first reflector 15 rises.

[0079] Specifically, the first reset elastic member 16 is a helical spring.

[0080] As Figure 4 and Figure 5 shown, in a feasible implementation, the windage adjustment mechanism 132 includes: a windage adjustment lead screw 1321, a windage adjustment block 1322, a second clearance elimination member 1323, and a guide shaft 1324. The windage adjustment lead screw 1321 is rotatably connected to the housing 11. The first end of the windage adjustment lead screw 1321 extends out of the housing 11, and a second adjustment part is arranged on the first end of the windage adjustment lead screw 1321 to drive the windage adjustment lead screw 1321 to rotate relative to the housing 11 by adjusting the second adjustment part. The windage adjustment block 1322 is sleeved outside the windage adjustment lead screw 1321. The windage adjustment block 1322 is in threaded cooperation with the windage adjustment lead screw 1321. The windage adjustment block 1322 is attached to the first reflector 15. By moving the windage adjustment block 1322 along the axial direction of the windage adjustment lead screw 1321, the first reflector 15 is driven to rotate relative to the compensation lens frame 14. The second clearance elimination member 1323 is arranged on the windage adjustment lead screw 1321. The second clearance elimination member 1323 is located on both sides of the windage adjustment lead screw 1321. The first end of the second clearance elimination member 1323 is attached to the housing 11, and the second end of the second clearance elimination member 1323 is attached to the windage adjustment block 1322. The guide shaft 1324 is arranged parallel to the windage adjustment lead screw 1321, and the windage adjustment block 1322 is slidably connected to the guide shaft 1324.

[0081] In this technical solution, the windage adjustment lead screw 1321 is rotatably connected inside the housing 11. A second adjustment part is provided at one end of the windage adjustment lead screw 1321 that protrudes from the housing 11. By manipulating the second adjustment part, the windage adjustment lead screw 1321 rotates relative to the housing 11, causing the windage adjustment block 1322 threadedly connected to the windage adjustment lead screw 1321 to move axially along the windage adjustment lead screw 1321. Furthermore, the windage adjustment block 1322 pushes the first reflector 15 to rotate, changing the position of the first reflector 15 relative to the optical component 12, causing the position of the aiming point to change, and thus realizing the adjustment of the windage position. By providing second backlash eliminators 1323 on both sides of the windage adjustment block 1322, pressing forces are provided for the trajectory adjustment blocks 1312 on both sides of the windage adjustment block 1322 to eliminate the threaded transmission clearance between the windage adjustment lead screw 1321 and the windage adjustment block 1322, ensuring the accuracy of the movement of the windage adjustment block 1322, and thereby improving the accuracy of the adjustment of the first reflector 15 by the windage adjustment block 1322. By slidingly connecting the windage adjustment block 1322 to the guide shaft 1324, the movement of the windage adjustment block 1322 is guided, restricting the degree of freedom of rotation of the windage adjustment block 1322, ensuring that when the windage adjustment lead screw 1321 makes a rotational movement, the windage adjustment block 1322 only moves axially along the windage adjustment lead screw 1321, further improving the accuracy of the movement of the windage adjustment block 1322, and thereby further improving the accuracy of the adjustment of the first reflector 15 by the windage adjustment block 1322 and improving the accuracy of windage adjustment.

[0082] In this technical solution, since the aiming position observed by the human eye 25 finally enters the human eye 25 after being reflected by the first reflector 15, when the first reflector 15 rotates to the left or to the right, the aiming position observed by the human eye 25 will change in the left - right direction, thereby realizing the adjustment of the windage position in the left - right direction.

[0083] It can be understood that when the windage adjustment lead screw 1321 rotates one full turn, the windage adjustment block 1322 moves a distance equal to one pitch.

[0084] Furthermore, a second support part is provided on the housing 11, and a second sliding groove is provided on the second adjustment part. The second support part is connected to the housing 11 through an elastic member. The second support part is in contact with and embedded in the second sliding groove to slidably or rollably support the second adjustment part through the second support part, ensuring the stability of the rotation of the second adjustment part and the windage adjustment lead screw 1321. As a preferred solution, balls are provided on the second support part, and the balls roll in the second sliding groove to rollably support the second adjustment part through the balls, improving the flexibility of the rotation of the second adjustment part and the windage adjustment lead screw 1321.

[0085] In some examples, the second adjusting part can adopt a knob structure, or a paddle structure, etc. As long as it is ensured that when the second adjusting part is manipulated, the windage adjusting lead screw 1321 can rotate synchronously with the second adjusting part in a timely manner.

[0086] As Figure 5 shown, in a feasible implementation, a third inclined surface 22 is provided on the side surface of the windage adjusting block 1322, and a fourth inclined surface 23 is provided on the first reflector 15. The fourth inclined surface 23 is attached to the third inclined surface 22 to drive the first reflector 15 to rotate by moving the windage adjusting block 1322.

[0087] In this technical solution, when the windage adjusting block 1322 moves along the axial direction of the windage adjusting lead screw 1321, the contact position between the third inclined surface 22 on the side wall of the windage adjusting block 1322 and the fourth inclined surface 23 on the side wall of the first reflector 15 changes, and the pressure of the third inclined surface 22 on the fourth inclined surface 23 changes, thereby driving the first reflector 15 to rotate to the left or right around its own rotation axis to adjust the left and right positions of the first reflector 15.

[0088] Furthermore, the slopes of the third inclined surface 22 and the fourth inclined surface 23 match to ensure full contact when the third inclined surface 22 and the fourth inclined surface 23 slide relative to each other.

[0089] It can be understood that the rotation axis of the first reflector 15 is the first pin shaft.

[0090] In some examples, as Figure 4 shown, when the windage adjusting lead screw 1321 drives the windage adjusting block 1322 to move in the direction close to the second adjusting part, the windage adjusting block 1322 climbs along the third inclined surface 22, increasing the contact pressure between the first reflector 15 and the windage adjusting block 1322. Under the pressure of the windage adjusting block 1322, the first reflector 15 rotates counterclockwise around its own rotation axis, and the position of the first reflector 15 changes to the right.

[0091] As Figure 4 and Figure 5 shown, in a feasible implementation, the off-axis optical sight further includes: a second reset elastic member 18 and a limiting groove 19; the first end of the second reset elastic member 18 is provided on the compensation frame 14, and the second end of the second reset elastic member 18 is provided on the first reflector 15; the limiting groove 19 is provided on the first reflector 15, and the second end of the second reset elastic member 18 is embedded in the limiting groove 19.

[0092] In this technical solution, the second reset elastic member 18 is disposed between the compensation lens frame 14 and the first reflector 15. The first reflector 15 is pulled back by the restoring force of the second reset elastic member 18 to ensure that the frame of the first reflector 15 can always be in contact with the wind deviation adjustment block 1322, guaranteeing the accuracy of the adjustment of the wind deviation adjustment block 1322 to the frame of the first reflector 15, and at the same time helping the frame of the first reflector 15 to quickly reset. The limiting groove 19 is disposed on the back surface of the first reflector 15, and the second reset elastic member 18 is embedded in the limiting groove 19 to limit the second reset elastic member 18 through the limiting groove 19, preventing the second reset elastic member 18 from shifting and ensuring the stable and reliable structure of the second reset elastic member 18.

[0093] Further, the second reset elastic member 18 is disposed near the first pin shaft.

[0094] In some examples, as Figure 4 shown, when the wind deviation adjustment lead screw 1321 drives the wind deviation adjustment block 1322 to move away from the second adjustment portion, the wind deviation adjustment block 1322 climbs up and down along the third inclined surface 22, reducing the contact pressure between the first reflector 15 and the wind deviation adjustment block 1322. Under the elastic force of the second reset elastic member 18, the first reflector 15 rotates clockwise around its own rotation axis, and the position of the first reflector 15 changes to the left.

[0095] Specifically, the second reset elastic member 18 is a torsion spring.

[0096] As Figure 4 and Figure 5 shown, in a feasible implementation manner, the wind deviation adjustment mechanism 132 is located on the side of the adjustment mechanism 13 close to the optical component 12, and the compensation lens frame 14 is rotatably connected to the wind deviation adjustment mechanism 132.

[0097] In this technical solution, the first reflector 15 is integrated with the wind deviation adjustment mechanism 132, and the compensation lens frame 14 rotates around the axis of the wind deviation adjustment lead screw 1321, with a compact structure, reducing the space occupied, reducing the overall volume of the off-axis optical sight, and being beneficial to the miniaturization of the off-axis optical sight.

[0098] Further, the compensation lens frame 14 is provided with mounting holes, and bearings are installed in the mounting holes. The compensation lens frame 14 is rotationally connected to the wind deviation adjustment lead screw 1321 through the bearings to prevent rotational interference between the wind deviation adjustment lead screw 1321 and the compensation lens frame 14, enabling the rotation of the compensation lens frame 14 around the wind deviation adjustment lead screw 1321 and the rotation of the wind deviation adjustment lead screw 1321 itself to not affect each other, ensuring the flexibility and accuracy of the rotation of the wind deviation adjustment lead screw 1321 and the compensation lens frame 14.

[0099] Further, the guiding shaft 1324 is arranged on the compensation spectacle frame 14, and a mating hole matching the guiding shaft 1324 is also arranged on the compensation spectacle frame 14. Through the auxiliary positioning of the mating structure, the ballistic adjustment mechanism 131 and the windage adjustment mechanism 132 are integrated with the compensation spectacle frame 14 into one body.

[0100] As Figure 6 shown, in a feasible implementation manner, the housing 11 includes a base 111 and a housing 112. The housing 112 is buckled on the base 111. The optical assembly 12 includes: a light source 121, a second reflector 122, a matching filter 123, and a holographic display window 124. The light source 121 is located below the compensation spectacle frame 14. The light source 121 is horizontally arranged on the base 111 so that the light source 121 emits a horizontal first light beam. The second reflector 122 is arranged on the base 111 at an angle. The second reflector 122 is opposite to the light source 121. The second reflector 122 reflects the light beam emitted by the light source 121 towards the first reflector 15. The matching filter 123 is vertically arranged on the housing 112. The matching filter 123 is opposite to the first reflector 15. The matching filter 123 receives the light beam reflected by the first reflector 15. The holographic display window 124 is arranged on the housing 112. The holographic display window 124 is located above the matching filter 123. The holographic display window 124 receives the light beam transmitted by the matching filter 123.

[0101] In this technical solution, the light source 121 horizontally emits a first light beam towards the direction where the second reflector 122 is located. The light beam is reflected by the second reflector 122 and then shoots towards the first reflector 15. The light beam reflected by the first reflector 15 shoots towards the matching filter 123. After being filtered and refracted by the matching filter 123, it reaches the holographic display window 124. By adjusting the vertical position and horizontal position of the first reflector 15, the propagation path of the light is changed, so that the image formed by the optical assembly 12 on the holographic display window 124 coincides with the incident light of the target 24, realizing the aiming function of the off-axis optical sight.

[0102] It can be understood that the off-axis optical sight adopts a transmissive optical system and utilizes a folded optical path. After the first light beam emitted by the light source 121 is shaped by the optical assembly 12, a required light beam waveform is formed, and then it enters the holographic optical element - the holographic display window 124. The diffraction wave of the holographic display window 124 forms a collimated aiming reticle virtual image. By making the aiming reticle virtual image coincide with the incident light from the target, that is, the reticle image is aligned with the target 24, the aiming function of the off-axis optical sight can be realized.

[0103] Specifically, the light source 121 is a laser.

[0104] Further, a sealing groove is provided at the bottom of the housing 112, and a sealing part is arranged in the sealing groove. After the housing 112 is connected to the base 111, it is sealed through the sealing part to realize the sealing of the internal structural parts of the aiming scope.

[0105] Further, a sealing ring is arranged on the ballistic adjustment lead screw 1311 to seal the ballistic adjustment lead screw 1311 and the housing 112; a sealing ring is arranged on the windage adjustment lead screw 1321 to seal the windage adjustment lead screw 1321 and the housing 112.

[0106] As Figure 6 and Figure 7 shown, in a feasible embodiment, the optical assembly 12 further includes: a front window glass 125 and a diaphragm 126; the front window glass 125 is arranged on the housing 112, and the optical centers of the front window glass 125 and the holographic display window 124 are located on a first straight line; the diaphragm 126 is arranged between the light source 121 and the second reflector 122; wherein, the first straight line is parallel to the straight line where the first light beam is located.

[0107] In this technical solution, the optical centers of the front window glass 125 and the holographic display window 124 are located on a straight line parallel to the first light beam, ensuring that the aiming reticle virtual image can be directly projected onto the image of the target 24, reducing parallax, so that the user can more accurately judge the position of the target 24; the first light beam emitted by the light source 121 is shaped by the diaphragm 126 and then projected onto the second reflector 122 to reduce the stray light and scattered light in the first light beam, improve the coherence and quality of the light beam, contribute to adjusting the imaging quality of the subsequent aiming reticle virtual image, and facilitate observation.
