[0055] See also Figure 1 The sight linkage control device of one embodiment of the present application is applied to a sighting device in which a front end of a white light sight 10 is connected to an infrared sight 20, and comprises a first sensor 70, a second sensor 80 and a processor 90; the first sensor 70 is arranged on a sighting body ( Figure 1The second sensor 80 is arranged on the white light focusing ring 11 of the white light sight 10; the processor 90 is connected to the first sensor 70 and the second sensor 80 (wired or wireless) by signal to monitor the relative rotation angle of the white light focusing ring 11 relative to the sight body. The relative rotation angle obtained by the processor 90 is used to adjust the infrared image display magnification of the infrared sight 20, so as to realize the linkage adjustment of the infrared image display magnification of the infrared sight 20 based on the white light focusing ring 11.

[0056] Please refer to Figure 2 and Figure 3 The scope linkage control device of one embodiment of the present application is installed on a sighting device whose front end of a white light scope 10 is connected to an infrared scope 20 for use, wherein the infrared scope 20 is fixedly connected to the front end of the white light scope 10 through an adapter ring 30; a scope bracket 40 is connected to the bottom of the white light scope 10, which is used to install the white light scope 10 equipped with the scope linkage control device on a gun. After the infrared scope 20 is fixed to the white light scope 10 through the adapter ring 30, there will be no relative movement between the infrared scope 20 and the white light scope 10 as a whole. After the white light scope 10 is fixed to the gun through the scope bracket 40, the scope linkage control device and the white light scope 10 move together with the gun as a whole.

[0057] In order to realize the linkage control of the infrared sight 20 and the white light sight 10, the sight linkage control device further includes a sensing module 50, which can be connected to the white light focusing ring 11 of the white light sight 10 to sense the angle change of the white light focusing ring 11. In order to facilitate the installation and connection of the sensing module 50 and the white light focusing ring 11, the sight linkage control device is further provided with a sensing module fixing seat 60, and the sensing module 50 is installed on the sensing module fixing seat 60 and connected to the white light focusing ring 11 through the sensing module fixing seat 60.

[0058] See also Figure 4 The sensing module 50 includes a sensing circuit board 51, which is installed in a housing composed of an upper housing 52 and a lower housing 53. The sensing circuit board 51 has its own battery, which can drive the sensing circuit board 51 and the electronic components arranged on the sensing circuit board 51 to work.

[0059] The sensing module fixing seat 60 includes a connecting portion 61 and a sensing module slot 62, and the connecting portion 61 and the sensing module slot 62 form an integral body. The connecting portion 61 is used to connect with the white light focusing ring 11 of the white light sight 10, and the shape of the sensing module slot 62 matches the shape of the sensing module 50, so that the sensing module 50 can be fixed in the sensing module slot 62 by snapping. In the illustrated embodiment, the sensing module fixing seat 60 is attached to the bottom surface of the white light focusing ring 11 by means of, for example, double-sided tape, that is, the connecting portion 61 is in an arc shape that matches the white light focusing ring 11, and the inner side of the connecting portion 61 adheres to the outer side of the bottom of the white light focusing ring 11. It should be pointed out that the fixing method of the sensing module fixing seat 60 and the white light focusing ring 11 is not limited to the attachment method. For example, it can also be connected by a snap-fit ​​connection of a buckle claw structure, or locked and fixed by a threaded connection of a screw member.

[0060] Since the sizes of the white light sight 10 vary depending on the model, the size of the connecting portion 61 of the sensing module fixing seat 60 can be adjusted according to the diameter of the white light focusing ring 11. Alternatively, the connecting portion 61 can be a flexible structure, for example, the connecting portion 61 is an arc-shaped structure that can be flexibly deformed to match white light focusing rings 11 of different sizes.

[0061] In a specific embodiment, the first sensor 70 is disposed in the infrared sight 20; the processor 90 and the second sensor 80 are integrated in the sensing module 50, the sensing module 50 is disposed in the white light focusing ring 11, and the processor 90 is connected to the infrared sight 20 by signal. Figure 5 , the infrared sight 20 is provided with a first sensor 70, and the first sensor 70 is used to monitor the angle change of the infrared sight 20. The sensing module 50 is provided with a second sensor 80, which is used to monitor the angle change of the white light focusing ring 11. The sensing module 50 is also provided with a processor 90, and the processor 90 has a communication module 91. The infrared sight 20, the first sensor 70 and the processor 90 are interconnected by wireless signals through the communication module 91. For example, the communication module 91 can use wireless signal transmission protocols such as WiFi, Bluetooth, infrared, ZigBee, etc. for communication. The second sensor 80 and the processor 90 can be arranged on the sensing circuit board 51, and can be powered by the sensing circuit board 51. The angle change sensing results of the first sensor 70 and the second sensor 80 can also be transmitted to the processor 90 on the sensing circuit board 51 for data processing. The processor 90 can send the calculated relative rotation angle to the infrared sight 20 through the communication module 91, or it can directly send the calculated adjustment change relative to the current infrared image display magnification to the infrared sight 20.

[0062] In another specific embodiment, the first sensor 70 and the processor are both disposed in the infrared sight 20, the second sensor 80 is integrated in the sensing module 50, the sensing module 50 is disposed in the white light focusing ring 11, and the processor 90 is connected to the sensing module 50 by signal. Figure 6 In another embodiment, the processor 90 may be disposed in the infrared sight 20. The processor 90 and the first sensor 70 in the infrared sight 20 may be connected by wire for signal transmission, and the second sensor 80 and the processor 90 may be connected by wireless signals through a communication module 91. The processor 90 may calculate the relative rotation angle based on the angle change sensing result of the first sensor 70 and the second sensor 80, or directly calculate the adjustment change relative to the current infrared image display magnification, and the infrared sight 20 adjusts the infrared image display magnification according to the calculation result of the processor 90.

[0063] In some embodiments, the first sensor 70 and the second sensor 80 may be angle sensors respectively, and the processor 90 may obtain the relative rotation angle according to the difference between the angle change of the white light focus ring 11 sensed by the second sensor 80 and the angle change of the scope body sensed by the first sensor 70. More specifically, the first sensor 70 and the second sensor 80 may use a gyroscope to sense the angle change, and the gyroscope is an angular velocity detection device, and the current angle change can be obtained through the gyroscope.

[0064] The working process of the above-mentioned sight linkage control device is as follows: the first sensor 70 obtains the angle change of the infrared sight 20, and the second sensor 80 obtains the angle change of the white light focusing ring 11. When the gun installed with the sighting device moves as a whole and the white light focusing ring 11 is not adjusted, there is no relative movement between the first sensor 70 (infrared sight 20) and the second sensor 80 (white light focusing ring 11). At this time, the angle change of the infrared sight 20 obtained by the first sensor 70 is the same as the angle change of the white light focusing ring 11 obtained by the second sensor 80. When only the white light focusing ring 11 of the white light sight 10 is rotated for focusing, the white light focusing ring 11 and the infrared sight 20 will rotate relative to each other. At this time, the angle change of the infrared sight 20 obtained by the first sensor 70 is different from the angle change of the white light focusing ring 11 obtained by the second sensor 80, and the infrared image display magnification of the infrared sight 20 needs to be adaptively adjusted. That is, at this time, it is necessary to zoom in and out (adjust the display magnification of the infrared image on the UI) on the user interface (UI) of the infrared sight 20 to adapt to the focal length change of the white light sight 10.

[0065] After simultaneously receiving the angle change obtained by the first sensor 70 and the angle change obtained by the second sensor 80, the processor 90 can perform data processing to obtain the relative rotation angle, and based on this, determine whether the infrared image display magnification of the infrared sight 20 needs to be adjusted and the specific adjustment parameters, thereby realizing automatic sensing and linkage adjustment.

[0066] Please refer to Figure 7 and Figure 8 , a sight linkage control device of another embodiment of the present application is installed on the white light sight 10 of the sighting device for use. In order to realize the linkage control of the infrared sight 20 and the white light sight 10, the sight linkage control device also includes a sensing module 50. The sensing module 50 can be connected to the white light sight body 12 of the white light sight 10 to sense the relative angle change of the white light focusing ring 11. In order to facilitate the installation and connection between the sensing module 50 and the white light sight body 12, the sight linkage control device is also provided with a sensing module fixing seat 60. The sensing module 50 is installed on the sensing module fixing seat 60 and connected to the white light sight body 12 through the sensing module fixing seat 60.

[0067] See also Fig. 9 , the sensing module 50 includes a sensing circuit board 51, which is installed in a housing composed of an upper shell 52 and a lower shell 53. The sensing circuit board 51 has its own battery, which can drive the sensing circuit board 51 and the electronic components arranged on the sensing circuit board 51 to work. In the illustrated embodiment, the sensing module fixing seat 60 is attached to the bottom surface of the white light sight body 12 by means of, for example, double-sided adhesive tape. It should be pointed out that the fixing method of the sensing module fixing seat 60 and the white light sight body 12 is not limited to the attachment method. For example, it can also be connected by a snap-on structure, or locked and fixed by a threaded connection of a screw. Specifically, the sensing module fixing seat 60 includes a connecting portion at the upper end, which is used to connect with the white light sight body 12, and the connecting portion is in an arc shape matching the white light sight body 12, and the inner side of the connecting portion is adhered to the outer side of the bottom of the white light sight body 12; the sensing module 50 can be directly fixed to the lower end of the sensing module fixing seat 60 by means of thread, adhesion, and snap-on. Since the sizes of the day light sight 10 vary depending on the model, the size of the connecting portion may be adjusted according to the diameter of the day light sight body 12; alternatively, the connecting portion may adopt a flexible structure, such as an arc-shaped structure that can undergo flexible deformation to match white light sight bodies 12 of different sizes.

[0068] It should also be pointed out that in the illustrated example, the second sensor 80 is separately connected to the white light focusing ring 11, so the shape of the second sensor 80 matches the white light focusing ring 11, and the second sensor 80 can be installed on the white light focusing ring 11 by attachment or the like.

[0069] In a specific embodiment, the second sensor 80 is disposed on the white light focusing ring 11, the processor 90 and the first sensor 70 are integrated into the sensing module 50, the sensing module 50 is disposed on the white light sight body 12, and the processor 90 is connected to the infrared sight 20 by signal. Fig.10 , the processor 90 can be set in the sensing module 50. The processor 90 and the first sensing element 70 are integrated in the sensing module 50, and the processor 90 and the first sensing element 70 can be connected by wire for signal transmission, and the processor 90 and the infrared sight 20 are connected by wireless signals through the communication module 91. The processor 90 can send the relative rotation angle obtained by the first sensing element 70 and the second sensing element 80 or the calculated adjustment change relative to the current infrared image display magnification to the infrared sight 20 through the communication module 91.

[0070] In another specific embodiment, the first sensor 70 is disposed on the white light sight body 12, the processor 90 and the second sensor 80 are integrated in the sensing module 50, the sensing module 50 is disposed on the white light focusing ring 11, and the processor 90 is respectively connected to the first sensor 70 and the infrared sight 20 by signal. Fig.11 In another embodiment, the processor 90 and the second sensor 80 are integrated in the sensing module 50, and the processor 90 and the infrared sight 20 are connected by wireless signals through the communication module 91. The processor 90 can send the relative rotation angle obtained by the first sensor 70 and the second sensor 80 or the calculated adjustment change relative to the current infrared image display magnification to the infrared sight 20 through the communication module 91. In some embodiments, the first sensor 70 and the second sensor 80 can also use the Hall effect to sense the relative angle change of the white light focusing ring 11 relative to the sight body (white light sight body 12). Specifically, the first sensor 70 and the second sensor 80 form a Hall sensor, and one of them is a Hall element and the other is a magnetic element. The first sensor 70 is arranged on the white light sight body 12 and is adjacent to the white light focusing ring 11. The processor 90 converts the relative rotation angle according to the measured magnetic flux change between the first sensor 70 and the second sensor 80. That is, the first sensor 70 , the second sensor 80 and the processor 90 may form a Hall angle sensor, the working principle of which is based on the Hall effect and uses the influence of the magnetic field on the Hall element to measure the angle.

[0071] In some other embodiments, the first sensing element 70 and the second sensing element 80 may also use a sliding rheostat to sense the relative angle change of the white light focusing ring 11 relative to the sight body (white light sight body 12). Specifically, the first sensing element 70 and the second sensing element 80 form a sliding rheostat, one of the fixed end and the sliding end of the sliding rheostat is set on the white light sight body 12, and the other is set on the white light focusing ring 11. The processor 90 converts the measured resistance value change between the first sensing element 70 and the second sensing element 80 (the sliding end relative to the fixed end) to obtain the relative rotation angle.

[0072] The present application also provides a linkage control method for the linkage control device of the above-mentioned sight. Because there are many models of white light sights 10 on the market, and the change magnifications are different, it is necessary to calibrate them before the first use. Fig.12 and Fig.13 In the linkage control method of the sight linkage control device of the present application, the calibration of the sight linkage control device includes the following steps:

[0073] S1, rotate the white light focusing ring 11 to the minimum white light magnification position and record the rotation angle as the minimum magnification rotation angle X min , adjust the infrared image display magnification of the infrared sight 20 to match the current white light image magnification and record it as the minimum magnification infrared image display magnification Y min .

[0074] Adjust the white light focusing ring 11 to the minimum magnification, open the infrared sight 20 menu settings, adjust the infrared image display magnification to adapt to the white light magnification at this time, and record the infrared image display magnification as Y min , record this position as the initial position.

[0075] When the first sensing element 70 and the second sensing element 80 are angle sensors respectively, the angle change amount obtained by the first sensing element 70 is A min1 The angle change obtained by the second sensor 80 is A min2 , then the minimum rotation angle X min =A min2 -A min1 When the first sensing element 70 and the second sensing element 80 cooperate with each other to form an angle sensor, the minimum magnification rotation angle X can be directly measured based on the first sensing element 70 and the second sensing element 80. min .

[0076] S2, rotate the white light focusing ring 11 to the maximum white light magnification position and record the rotation angle as the maximum magnification rotation angle X max, adjust the infrared image display magnification of the infrared sight 20 to match the current white light magnification and record it as the maximum magnification infrared image display magnification Y max .

[0077] Adjust the white light focusing ring 11 to the maximum magnification, adjust the infrared image display magnification of the infrared sight 20 to adapt to the white light magnification at this time, and record the infrared image display magnification as Y max , record this position as the end position.

[0078] When the first sensing element 70 and the second sensing element 80 are angle sensors respectively, the angle change amount obtained by the first sensing element 70 is B max1 The angle change obtained by the second sensor 80 is B max2 , then the maximum rotation angle X max =B max2 -B max1 When the first sensing element 70 and the second sensing element 80 cooperate with each other to form an angle sensor, the maximum magnification rotation angle X can be directly measured based on the first sensing element 70 and the second sensing element 80. max .

[0079] S3, rotate angle X according to the minimum magnification min , Maximum rotation angle X max 、Minimum magnification of infrared image display magnification Y min 、Maximum magnification of infrared image display magnification Y max , set the corresponding relationship between the infrared image display magnification Y and the relative rotation angle X.

[0080] The adjustment variation ΔY of the infrared image display magnification Y between the initial position and the end position and the relative rotation angle X can be set to have a linear corresponding relationship.

[0081] That is, the relationship between the adjustment change ΔY and the relative rotation angle X is as follows: ΔY=kX, where k=(Y min -Y max ) / (X min -X max ). That is, the adjustment change ΔY of the infrared image display magnification Y is linearly linked with the relative rotation angle X, such as Fig.12 as shown in .

[0082] The calibration of the sight linkage control device is completed through the above steps. When working after the calibration is completed, the linkage control method of the sighting device of the present application also includes the following steps:

[0083] S4, obtaining a relative rotation angle X of the white light focusing ring 11 relative to the scope body based on the first sensing element 70 and the second sensing element 80.

[0084] When the first sensor 70 and the second sensor 80 are angle sensors, the first sensor 70 senses the current angle change A1, and the second sensor 80 senses the current angle change A2. Based on the angle change A1 and the angle change A2, the relative rotation angle X of the white light focusing ring 11 relative to the scope body is calculated, and the calculation formula of the relative rotation angle X is as follows: X=A2-A1.

[0085] When the first sensing element 70 and the second sensing element 80 cooperate with each other to form an angle sensor (such as a Hall effect sensing angle or a sliding rheostat measuring angle), the first sensing element 70 and the second sensing element 80 obtain the relative rotation angle X by direct measurement.

[0086] S5, determining whether the relative rotation angle X of the current position is zero.

[0087] If so, it is determined that the white light focus ring 11 is not adjusted, and there is no need to adjust the infrared image display magnification Y.

[0088] If not, the process proceeds to S6 to adjust the infrared image display magnification Y of the infrared sight 20 based on the relative rotation angle X.

[0089] Specifically, based on the corresponding relationship ΔY=kX between the relative rotation angle X, the adjustment change ΔY and the relative rotation angle X, the infrared image display magnification Y of the infrared sight 20 is adjusted.

[0090] In this way, the infrared image display magnification Y of the infrared sight 20 is adjusted in conjunction with the focusing rotation of the white light focusing ring 11 of the white light sight 10 .

[0091] Different from the prior art method of manually operating buttons or knobs to adjust the infrared image display magnification of the front infrared sight to match the white light sight, the sight linkage control device and linkage control method of the present application automatically adjusts the infrared image display magnification of the infrared sight by sensing the relative rotation angle of the white light focusing ring relative to the sight body, thereby realizing linkage adjustment between the focusing magnification of the white light sight and the infrared image display magnification of the front infrared sight, and synchronizing the white light magnification change caused by focusing of the white light sight to the infrared sight.

[0092] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0093] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
