[0049] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] The invention provides a sighting scope with a movable focal plane for focusing.

[0052] In the embodiment of the present invention, please refer to Figures 1 to 8 as well as Fig.10 The sight includes a main body 100 and a focusing assembly 20, wherein the main body 100 includes a housing 11 and an image sensor 15, the housing 11 extends in a long strip shape along the front-back direction, the image sensor 15 and the focusing assembly 20 are both arranged in the housing 11, and the focusing assembly 20 is located behind the image sensor 15;

[0053] The focusing assembly 20 includes an adjusting member 21 and a translation member 22 which is transmission-connected to the adjusting member 21, wherein the adjusting member 21 can rotate around a rotation axis, the rotation axis intersects with the front-rear direction, and the rotation axis and the axis of the outer peripheral surface of the adjusting member 21 are staggered with each other in the front-rear direction;

[0054] The translation member 22 is provided with an adjustment hole 241 corresponding to the adjustment member 21. The adjustment hole 241 is sleeved on the periphery of the adjustment member 21, and the inner circumference of the adjustment hole 241 is adapted to the maximum swept outer diameter of the adjustment member 21. The outer circumference of the adjustment member 21 abuts against the inner circumference of the adjustment hole 241 in the front-to-back direction and can be slidably matched around the rotation axis. The translation member 22 is fixedly connected to the image sensor 15.

[0055] In the present embodiment, it is understandable that the sight mainly includes a white light sight and a digital low light sight. The structure of the white light sight is relatively simple, mainly consisting of a lens barrel, an objective lens 300 and an eyepiece 400 arranged in the lens barrel. Therefore, the lens barrel of the traditional white light sight is mostly slender, and its mass is relatively dispersed. During installation, two supports 600 are often used to install the white light sight on the upper part of the gun. The two supports 600 are arranged at intervals along the axial direction of the lens barrel, so the stability of the white light sight after installation is relatively good. The adaptability of the digital low light sight at night has been recognized by the majority of users, but the digital low light sight on the market is usually short and thick, and its mass distribution is relatively concentrated, and the stability after being installed on the gun is not as good as that of the white light sight.

[0056] The sight of the present invention has both the appearance of a white light sight and the functional components of a digital sight, so that the sight has the advantages of good adaptability of a white light sight and the function of digital imaging of a digital sight. It is understandable that the digital sight can also increase the night vision function by providing a low-light imaging sensor, and an infrared fill light can be configured to enhance the night vision function. Furthermore, in order to increase the distance measurement function, a laser distance measurement device can also be configured.

[0057] It is understandable that the existing sights set the focusing ring of the objective lens 300 on the periphery of the objective lens 300. This will, on the one hand, cause the weight of the front end of the sight to be more concentrated, and the front end tends to sink more during use, increasing the difficulty of maintaining stability; on the other hand, the distance between the objective lens 300 and the eyepiece 400 is far, and the user needs to stretch the hand long enough when manually focusing, but it is difficult to maintain the stability of the hand while the hand is stretched, and the hand may shake slightly, which in turn affects the accuracy of focusing, resulting in a poor user experience.

[0058] On this basis, the mobile focal plane focusing sight of the present invention sets the focusing assembly 20 at the rear of the image sensor 15, so as to achieve focusing at the rear section of the sight. At the same time, the overall mass of the sight can be dispersed, and the stability can be better when installed on a gun, and the distance between the user and the focusing assembly 20 of the objective lens 300 can be retracted, so that when manual focusing is required, the user can retain the original focusing habit of using the white light sight, and at the same time, the hand does not need to be fully extended when focusing, and the core of the arm can be better tightened to maintain the stability of the arm to prevent shaking during focusing, thereby improving the user's experience.

[0059] The image sensor 15 and the focusing assembly 20 are both disposed in the housing 11, and the focusing assembly 20 is located behind the image sensor 15, so that the focusing assembly 20 is close to the user, which is convenient for the user to operate. At the same time, compared with the traditional focusing method by moving the lens assembly, the present adjustment method by moving the image sensor 15 can make the focusing range larger, and the present invention does not exclude the traditional focusing method by moving the lens assembly. The two methods can be used in combination to further increase the focusing range of the present sight. It can be understood that the focusing referred to in this article means adjusting the relative position relationship between the focal plane and the lens assembly.

[0060] It is understandable that the focusing structure of the present invention may be an automatic focusing structure, a manual focusing structure, or a combination of automatic focusing and manual focusing, which is not limited here and can be selected according to actual conditions.

[0061] In this embodiment, the focusing assembly 20 is a reciprocating cam mechanism, and the rotation axis of the adjusting member 21 and the axis of the outer peripheral surface of the adjusting member 21 are staggered in the front-to-back direction, so that the adjusting member 21 is equivalent to an eccentric wheel, and the outer peripheral surface of the adjusting member 21 abuts against the inner peripheral surface of the adjusting hole 241 in the front-to-back direction. Therefore, after the adjusting member 21 rotates around the rotation axis, the outer peripheral surface of the adjusting member 21 and the inner peripheral surface of the adjusting hole 241 can slide together around the rotation axis, so that the translation member 22 can move forward or backward, and then can drive the image sensor 15 to move forward or backward.

[0062] The shape of the translation member 22 can be plate-shaped or cylindrical, which is not limited here, as long as the translation member 22 is provided with an adjustment hole 241 that cooperates with the adjustment member 21 and can move forward and backward.

[0063] The housing 11 extends along the front-to-back direction, and the rotation axis intersects the front-to-back direction, that is, an angle is formed between the rotation axis and the front-to-back direction, and the angle is preferably about ninety degrees.

[0064] The present invention arranges the focusing assembly 20 on the rear side of the image sensor 15, and compared with arranging the focusing assembly 20 on the periphery of the objective lens 300, the distance between the focusing assembly 20 and the user is retracted. In the technical solution of manual focusing, it is convenient for the user to focus, that is, the hand does not need to be fully extended when focusing, and the core of the arm can be better tightened to maintain the stability of the arm to prevent shaking during focusing, and the user's experience is better. At the same time, it can also allow the user to retain the original focusing habit of the white light sight.

[0065] For further information, see Figure 2 A first opening 121 is provided on the side wall of the housing 11 corresponding to the adjusting member 21 ; the adjusting member 2 can be partially exposed from the housing 11 through the first opening 121 , and the image sensor 15 can move in the front-rear direction as the adjusting member 2 rotates.

[0066] In this embodiment, when the focusing assembly 20 is manually focused, in order to facilitate manual operation, a first opening 121 for exposing the adjusting member 2 is provided on the side wall of the housing 11. The user can twist the exposed portion of the adjusting member 2 to rotate the adjusting member 2, thereby allowing the translation member 22 to move in the front-to-back direction along with the rotation of the adjusting member 2. In this way, the image sensor 15 can move in the front-to-back direction along with the translation member 22 and focus.

[0067] It is understandable that in other embodiments, the exposed portion of the adjustment member 21 is fixedly connected to the focus knob 18, which can facilitate the user to turn the adjustment member 21, and can be sealed with the first opening 121 to prevent external water vapor from entering, and is also more beautiful in appearance. At the same time, the setting position of the focus knob 121 can be the same as the position of the focus knob of the original white light sight, so that the user can retain the focus habit of the original white light sight when focusing, thereby improving the user's experience.

[0068] For further information, see Figures 3 to 5 as well as Fig.10 The translation member 22 is provided with a through hole 242 opposite to and connected to the adjustment hole 241 in the direction of the rotation axis; the adjustment member 21 is cylindrical and the inner end is open; the focusing assembly 20 also includes a rotating shaft 26, which extends along the rotation axis in a long strip shape, and the rotating shaft 26 is fixed relative to the housing 11, and one end of the rotating shaft 26 passes through the through hole 242 and is embedded in the adjustment member 21; the axis of the inner circumference of the adjustment member 21 is coaxial with the rotation axis, and the inner circumference of the adjustment member 21 and the outer circumference of the rotating shaft 26 can be rotatably matched.

[0069] In this embodiment, if the translation member 22 is plate-shaped, the through hole 242 is the adjustment hole 241 ; if the translation member 22 is cylindrical, two through holes 242 are provided, and the one close to the adjustment member 21 is the adjustment hole 241 .

[0070] The inner end of the adjusting member 21 is open, so that the rotating shaft 26 is partially embedded in the adjusting member 21, so that the adjusting member 21 can rotate around the rotating shaft 26. The rotating shaft 26 is the rotation center of the adjusting member 21. The rotating shaft 26 is fixed to the housing 11, and one end of the rotating shaft 26 passes through the through hole 242 and extends into the adjusting member 21. It can be understood that the inner circumference of the adjusting member 21 and the outer circumference of the rotating shaft 26 can be just matched, or there can be a certain gap to facilitate the rotation of the adjusting member 21. As long as the axis of the inner circumference of the adjusting member 21 is coaxial with the rotation axis, it can be used.

[0071] For further information, see Figures 6 to 9 The translation member 22 is cylindrical and its axial direction is consistent with the front-to-back direction. The adjustment hole 241 and the through hole 242 are located on the opposite sides of the peripheral wall of the translation member 22 in the direction of the rotation axis; the outer peripheral surface of the translation member 22 and the inner peripheral surface of the shell 11 can be slidably matched along the front-to-back direction.

[0072] In this embodiment, the translation member 22 is cylindrical, which can make the sliding fit between the outer circumference of the translation member 22 and the inner circumference of the housing 11 in the front-to-back direction more stable, and can also make the image sensor 15 more stably installed on the translation member 22. A through hole 242 is provided on the peripheral wall of the translation member 22, and the through hole 242 can facilitate the rotation shaft 26 to pass through and be fixedly connected to the housing.

[0073] For further information, please refer to Figures 6 to 9 The translation member 22 includes a front section 23 and a rear section 24 connected to each other in the front-to-back direction. The wall thickness of the rear section 24 is greater than that of the front section 23. The adjustment hole 241 and the through hole 242 are both opened in the rear section 24. The front end of the front section 23 is fixedly connected to the image sensor 15.

[0074] In this embodiment, the wall thickness of the front section 23 and the rear section 24 of the translation member 22 is uneven, the wall thickness of the front section 23 is greater than that of the rear section 24, and the adjustment hole 241 and the through hole 242 are both provided in the rear section 24, so that the structural strength of the adjustment hole 241 and the through hole 242 can be enhanced. The rear section 24 makes the inner circumference of the adjustment hole 241 wider, and the adjustment hole 241 is not easily damaged when rotating with the adjustment member 21. The thinner setting of the front section 23 is conducive to increasing the internal space and facilitating the setting of the focusing assembly 20. At the same time, the weight of the translation member 22 can also be reduced, so that the overall weight of the device is smaller.

[0075] For further information, see Figure 8The outer circumference of the front section 23 is flush with the outer circumference of the rear section 24, and the inner circumference of the rear section 24 protrudes from the inner circumference of the front section 23. In this embodiment, the wall thickness of the translation member 22 increases toward the axis of the translation member 22, and such a setting will not affect the sliding fit between the outer circumference of the translation member 22 and the housing 11.

[0076] For further information, please refer to Figure 8 The outer circumferential surface of the front section 23 is provided with an annular groove 231, which extends in the middle and rear parts of the front section 23 along the front-to-back direction; the outer circumferential surface of the front end of the front section 23 and the outer circumferential surface of the rear section 24 are slidably matched with the inner circumferential surface of the shell 11 along the front-to-back direction.

[0077] In this embodiment, an annular groove 231 is provided in the front section 23 of the translation member 22, which can further form a larger wall thickness difference between the front section 23 and the rear section 24, and can also reduce the sliding fitting surface between the outer peripheral surface of the translation member 22 and the inner peripheral surface of the outer shell 11, thereby reducing the processing amount of the high-precision surfaces of the translation member 22 and the outer shell 11.

[0078] For further information, see Figure 2 A second opening 122 opposite to the first opening 121 is also provided on the side wall of the shell 11, and the end of the rotating shaft 26 away from the adjusting member 21 extends out of the shell 11 through the second opening 122, and the rotating shaft 26 is fixedly connected to the second opening 122; the rotating shaft 26 is provided with a cavity, and the end of the cavity away from the adjusting member 21 is open; the main body 100 also includes a cover body 16, which can detachably cover the opening.

[0079] In this embodiment, in order to facilitate processing and manufacturing, the second opening 122 and the first opening 121 are preferably set to be the same size. The rotating shaft 26 is a hollow structure and has a cavity. On the one hand, compared with a solid rotating shaft, the hollow rotating shaft 26 can reduce the weight of the sight; on the other hand, the hollow rotating shaft 26 can be placed with some parts that are easy to take and put, such as batteries 17. The rotating shaft 26 extends out of the housing 11 through the second opening 122, so that these parts can be easily taken and put. The cover body 16 can cover the opening of the rotating shaft 26. It can be understood that the cover body 16 can be detachably fixed to the housing 11 or the rotating shaft 26, which is not limited here, as long as it can cover the opening of the rotating shaft 26.

[0080] In a specific embodiment, the cover 16 is a knob of the sight, and the knob cover is arranged on the shaft 26, which can close the opening of the shaft 26 so that the parts in the inner cavity will not fall out. At the same time, using the knob as the cover 16 can make the appearance of the sight closer to the white light sight, and symmetrical with the focusing knob 18, which is more aesthetically pleasing.

[0081] Further, see Figures 3 to 5The main body 100 further includes a battery 17, which can be installed in the cavity through the opening. In this embodiment, compared with installing the battery 17 outside the housing 11, which makes the housing 11 appear bulky, installing the battery 17 in the inner cavity of the rotating shaft 26 will not affect the setting of the focusing assembly 20, and can facilitate the installation and replacement of the battery 17.

[0082] Further, see Fig.11 The rotating shaft 26 includes a peripheral side wall 28 and an end wall 27 connected to the peripheral side wall 28. The peripheral side wall 28 extends along the rotation axis. The end wall 27 and the peripheral side wall 28 enclose a cavity. The outer peripheral surface of the peripheral side wall 28 and the inner peripheral surface of the adjusting member 21 can be rotatably matched. The end wall 27 is provided at one end of the peripheral side wall 28 extending into the adjusting member 21.

[0083] The end wall 27 is provided with a first wire groove 271 communicating with the cavity; the peripheral side wall 28 is provided with a second wire groove 281 , which is communicated with the first wire groove 271 , and the second wire groove 281 extends on the peripheral side wall 28 to the outside of the coverage range of the adjustment member 21 .

[0084] In the present embodiment, it can be understood that, under the premise of not affecting the rotation of the adjusting member 21, in order to facilitate the wire passing of one end of the battery 17 located in the adjusting member 21, a first wire passing groove 271 is provided on the end wall 27, and the first wire passing groove 271 is communicated with the inner cavity so that the power cord can be extended into the cavity and electrically connected to the positive or negative pole of the battery 17, and the second wire passing groove 281 is for facilitating the power cord to extend from the inner cavity of the adjusting member 21 and be electrically connected to the control module 200 of the sight.

[0085] For further information, see Fig.10 , a third opening 123 is provided on the side wall of the housing 11, and the third opening 123 and the first opening 121 are staggered with each other in the circumferential direction of the housing 11;

[0086] The translation member 22 is cylindrical and its axial direction is consistent with the front-to-back direction. The rear end of the translation member 22 is open and adjacent to the rear edge of the third opening 123. The third opening 123 is connected to the inner cavity of the outer shell 11. The peripheral wall of the translation member 22 located on the front side of the adjusting member 21 is provided with a first wire hole 251. The first wire hole 251 is adjacent to the front edge of the third opening 123, and the first wire hole 251 connects the third opening 123 and the inner cavity of the translation member 22.

[0087] In this embodiment, in a specific embodiment, the control module 200 of the sight is arranged at the rear side of the housing 11, and the image sensor 15 needs to transmit the collected video signal to the control module 200 through the electrical connection line 151, and then transmit it to the display screen for display after being processed by the control module 200. Therefore, when the translation member 22 is cylindrical, the electrical connection line 151 needs to avoid the adjustment member 21 and then be electrically connected to the control module 200 and the image sensor 15. The housing 11 is provided with a third opening 123 for facilitating the passage of the electrical connection line 151, and the third opening 123 and the first opening 121 are staggered in the circumferential direction of the housing 11 so that the opening of the third opening 123 will not interfere with the first opening 121. The electrical connection line 151 can cross the adjustment member 21, one end can extend into the inner cavity of the translation member 22 through the third opening 123 and the first wire hole 251 to connect with the image sensor 15, and the other end can extend into the inner cavity of the housing 11 through the third opening 123 and connect with the control module 200.

[0088] Specifically, the main body 100 further includes a function knob 19 covering the third opening 123 , and the function knob 19 can be used as a control knob for the UI.

[0089] For further information, please refer to Fig.10 A second wire-passing hole 252 is provided on the peripheral wall of the translation member 22 located at the rear side of the adjustment member 21 . The second wire-passing hole 252 is adjacent to the rear edge of the third opening 123 , and the second wire-passing hole 252 communicates with the third opening 123 and the inner cavity of the housing 11 .

[0090] In this embodiment, in order to make the edge of the third opening 123 shorter in the front-to-back direction and ensure the structural strength of the side walls of the first opening 121 and the second opening 122 of the translating member 22, a second wire hole 252 is provided on the peripheral wall of the translating member 22 located at the rear side of the adjusting member 21, so that the other end of the electrical connection line 151 passes through the third opening 123, the second wire hole 252 and the rear opening of the translating member 22 to extend into the inner cavity of the housing and connect with the control module 200.

[0091] For further information, see Figure 7 as well as Fig. 9 The focusing assembly 20 further includes a reset member 29, which is elastically connected to the housing 11 and the translation member 22, so that the outer circumference of the adjustment member 21 and the inner circumference of the adjustment hole 241 are kept in contact in the front-to-back direction.

[0092] In this embodiment, the reset member 29 can make the translation member 22 quickly return to the initial position, so as to facilitate the next adjustment. It is understandable that the reset method of the reset member 29 can be a reset method such as a spring mechanism, a magnetic member, and a ratchet mechanism, which is not limited here and can be selected according to specific circumstances. The connection method and connection position of the reset member 29 on the housing 11 and the translation member 22 are not specifically limited here, and can be specifically selected according to actual conditions, as long as the reset member 29 can keep the outer circumference of the adjustment member 21 and the inner circumference of the adjustment hole 241 in contact in the front-to-back direction.

[0093] On the one hand, the reset member 29 can reduce the clearance between the housing 11 and the translation member 22 during the movement of the translation member 22 relative to the housing 11, that is, reduce the influence of the processing error on the sliding connection between the two when the two have a certain room for movement; on the other hand, the reset member 29 can eliminate the transmission error caused by the backlash to a certain extent, thereby solving the problem of the loose feel between the translation member 22 and the adjusting member 21 and facilitating the rotation of the adjusting member.

[0094] It is understandable that there is a gap between the translation member 22 and the housing 11. When the rotation direction of the adjustment member 21 changes, the translation member 22 cannot immediately produce reverse movement. The translation member 22 can only start to move in the opposite direction after the adjustment member 21 rotates to a certain angle. This phenomenon is called backlash, which will affect the transmission error.

[0095] For further information, please refer to Figure 1 , Figure 7 as well as Fig. 9 The housing 11 includes a barrel portion 12 and a head portion 13. The axial direction of the barrel portion 12 is consistent with the front-to-back direction. The first opening 121 is provided in the barrel portion 12. The head portion 13 is arranged to expand forward and radially outward from the front end of the barrel portion 12, and a forward step surface 14 is formed at the connection between the barrel portion 12 and the head portion 13.

[0096] The translation member 22 is cylindrical and its axial direction is consistent with the front-back direction. The outer peripheral surface of the front end of the translation member 22 is provided with an outer shoulder 232, and the outer shoulder 232 is located at the front side of the step surface 14;

[0097] The reset member 29 is a compression spring, which is sleeved on the outer peripheral surface of the translation member 22, and one end of the reset member 29 elastically abuts against the step surface 14, and the other end elastically abuts against the rearward side of the outer shoulder 232;

[0098] The image sensor 15 is located on the head 13 , and the image sensor 15 is fixedly connected to the front side of the outer shoulder 232 .

[0099] In this embodiment, the barrel 12 is connected to the rear side of the head 13, and the outer diameter of the barrel 12 is smaller than the outer diameter of the head 13, the objective lens 300 of the sight is installed in the head 13, and the infrared ranging module 500 of the sight is installed on the outer peripheral surface of the head 13. The first opening 121 is provided in the barrel 12, that is, the adjustment member 21 is provided in the barrel 12. The reset member 29 is sleeved on the outer peripheral surface of the translation member 22, one end of which elastically abuts against the forward step surface 14, and the other end of which elastically abuts against the outer convex shoulder 232. With such a configuration, the reset member 29 can elastically contact with the housing 11 and the translation member 22 in a relatively stable manner. The reset member 29 is specifically a compression spring. Compared with the reset method of other mechanisms, the reset mechanism structure using the compression spring is relatively simple and the cost is relatively low. At the same time, when the reset member 29 is a compression spring, the compression spring can be used to generate a unidirectional restoring force so that the working surfaces of the translation member 22 and the adjusting member 21 maintain single-sided contact, thereby eliminating the transmission error caused by the backlash to a certain extent, and then solving the problem of the loose feel between the translation member 22 and the adjusting member 21, facilitating the rotation of the adjusting member.

[0100] For further information, see Fig.10 The translation member 22 has a limiting surface 243 protruding from the inner circumference of the adjustment hole 241 . The limiting surface 243 is located on a side of the adjustment hole 241 away from the first opening 121 . The inner end surface of the adjustment member 21 is in limiting contact with the limiting surface 243 .

[0101] In this embodiment, the limit surface 243 can limit the insertion depth of the adjustment member 21 into the housing 11, so as to prevent the adjustment member 21 from being excessively inserted into the housing 11, thereby affecting the installation of other components. At the same time, it is also convenient for the adjustment member 21 to be quickly installed in place during installation. It can be understood that if the translation member 22 is cylindrical, two limit surfaces 243 are provided, and the two limit surfaces 243 are staggered in the circumferential direction of the adjustment hole 241. Specifically, the adjustment hole 241 only penetrates the side wall of one side of the translation member 22, so two limit surfaces 243 are formed at the deepest part of the adjustment hole 241.
