Description

Technical Field

[0001] This invention relates to the field of photoelectric observation technology, and in particular to a glass slide switching assembly and a photoelectric observation device. Background Technology

[0002] Optoelectronic observation and aiming devices can acquire target information using photoelectromagnetic spectrum information (visible light, infrared light, laser, etc.), and achieve target observation and aiming through electronic signal processing and image analysis. They are widely used in military, security, aerospace and civilian fields.

[0003] In related technologies, optoelectronic aiming devices use a slide switching assembly to replace different filters. Specifically, the slide switching assembly includes a base and a slide holder. The base has a slide window, and the slide holder is used to hold multiple slides. By driving the slide holder to move relative to the base so that the target slide is in the window position, slide switching can be achieved. However, when the vehicle (UAV, military vehicle, etc.) is in firing mode, a strong recoil force will be generated, causing the slide holder to change position and resulting in accidental slide switching. That is, the imaging stability of existing optoelectronic aiming devices is poor. Summary of the Invention

[0004] The main objective of this invention is to provide a slide switching assembly and a photoelectric observation and aiming device, which aims to solve the technical problem of poor imaging stability in photoelectric observation and aiming devices.

[0005] To achieve the above objectives, a first aspect of the present invention provides a slide switching assembly, comprising: The base has a window; A slide holder is movably connected to the base. The slide holder includes a first mounting position and a second mounting position arranged along a first direction. The first mounting position is used to load a first slide, and the second mounting position is used to load a second slide. The slide holder has a first position and a second position relative to the base. In the first position, the first slide covers the window, and in the second position, the second slide covers the window. The linkage mechanism includes a first rod and a second rod, both of which are rotatably connected to the base. One end of the second rod is movably connected to the first rod, and the other end is movably connected to the slide holder. When the first rod is driven to rotate, it can drive the second rod to rotate, thereby driving the slide holder to switch from the first position to the second position along the first direction. A limiting structure is connected to the base. The limiting structure is used to limit the rotation angle of the first rod body in the second position. The limiting structure is configured to cooperate with the linkage mechanism to self-lock, so as to limit the slide holder from switching from the second position to the first position in the opposite direction of the first direction.

[0006] In some embodiments, the first rod being driven to rotate can drive the second rod to rotate, thereby driving the slide holder to switch from the second position to the first position in the opposite direction of the first direction; at the first position, the limiting structure is configured to cooperate with the linkage mechanism to self-lock, thereby restricting the slide holder from switching from the first position to the second position in the first direction.

[0007] In some embodiments, the limiting structure includes a first limiting hole, and the first rod body is provided with a first connecting portion on the side facing the limiting structure, the first connecting portion passing through the first limiting hole; in the second position, the arrangement direction of the first rod body is perpendicular to the arrangement direction of the second rod body, and the first connecting portion abuts against the inner wall of the first limiting hole to restrict the second rod body from driving the first rod body to rotate.

[0008] In some embodiments, the limiting structure includes a second limiting hole communicating with the first limiting hole, the base is provided with a first rotating shaft, the second rod is provided with a first connecting hole, and the first rotating shaft passes through the first connecting hole and is disposed in the second limiting hole.

[0009] In some embodiments, the second rod body is provided with a second connecting hole, and the first connecting part passes through the second connecting hole and is disposed in the first limiting hole. During the process of the first rod body being driven to rotate, the first connecting part can move along the extension direction of the second connecting hole to drive the second rod body to rotate.

[0010] In some embodiments, the slide holder is provided with a third connecting hole, and the second rod is provided with a second connecting part on the side facing the slide holder. The second connecting part passes through the third connecting hole. During the process of the first rod driving the second rod to rotate, the second connecting part can move along the extension direction of the third connecting hole to drive the slide holder to move relative to the base.

[0011] In some embodiments, along the first direction, the base is provided with a first groove on the side facing the linkage mechanism, and at the first position, the end of the second rod opposite to the first rod is accommodated in the first groove; And / or, Along the first direction, the base is provided with a second groove on the side facing the linkage mechanism, and at the second position, one end of the second rod facing the first rod is accommodated in the second groove.

[0012] In some embodiments, the second rod body has a first protrusion on the side opposite to the first rod body, the first protrusion extending in a direction toward the limiting structure, and the first protrusion being used to abut against the limiting structure.

[0013] In some embodiments, the first protrusion is provided with a magnetic part, the magnetic part including a first N pole and a first S pole, and a magnetic ring is sleeved on the outer periphery of the first connecting part, the magnetic ring including a second N pole and a second S pole; from the first position to the second position, the magnetic part is adapted to drive the magnetic ring to rotate. At the first position, the first N pole magnetically attracts the second S pole to restrict the second rod from driving the first rod to rotate; at the second position, the first N pole magnetically attracts the second S pole to restrict the second rod from driving the first rod to rotate.

[0014] A second aspect of the present invention provides an optoelectronic observation and aiming device, comprising: The slide switching assembly as described in the above embodiments; and... A drive unit is connected to a first rod body, and the drive unit is used to drive the first rod body to rotate.

[0015] Compared with the prior art, the beneficial effects of the present invention include: In the technical solution of this invention, the slide switching assembly includes a base, a slide holder, a linkage mechanism, and a limiting structure. The base has a window. The slide holder includes a first mounting position and a second mounting position arranged along a first direction. The first mounting position is used to load a first slide, and the second mounting position is used to load a second slide. The slide holder is movably connected to the base and has a first position and a second position relative to the base. In the first position, the first slide is located in the window, and in the second position, the second slide is located in the window. The first and second rods of the linkage mechanism are both rotatably connected to the base. One end of the second rod is movably connected to the first rod, and the other end is movably connected to the slide holder. When the first rod is driven to rotate, it can drive the second rod to rotate, thereby driving the slide holder to switch from the first position to the second position along the first direction to achieve slide switching. In the prior art, when the vehicle (drone, military vehicle, etc.) is in a firing state, a strong recoil force is generated, causing the slide holder to change position and resulting in accidental slide switching. The limiting structure of this solution restricts the rotational position of the first rod. Furthermore, when the slide holder is in the second position, the limiting structure, in conjunction with the linkage mechanism, achieves self-locking, preventing the slide holder from switching from the second position to the first position in the reverse direction. In other words, the slide switching component of this solution can only drive the second rod through the first rod, thereby driving the slide holder to switch positions. This avoids the slide holder being affected by recoil vibrations and causing it to drive the linkage mechanism in the opposite direction. Therefore, this solution ensures the target slide remains stably in the window position, effectively reducing the possibility of accidental slide replacement due to recoil affecting the slide holder's position switching, significantly improving imaging stability, and ensuring the reliability of the optoelectronic observation and aiming device in complex combat environments.

[0019] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] The first aspect of this invention provides a slide switching assembly 10, which can effectively reduce the situation where the slide holder 200 is switched due to recoil force, resulting in accidental slide replacement. See below for further details. Figures 1 to 12The slide switching assembly 10 of this application embodiment will be introduced. Specifically, the slide switching assembly 10 includes a base 100, a slide holder 200, a linkage mechanism 300 and a limiting structure 400.

[0022] Reference Figures 1 to 4 The base 100 is provided with a window 110 for accommodating a glass slide. It can be understood that when the target glass slide is located at and covers the window 110, non-target light rays can be filtered while target light rays pass through, thereby achieving the corresponding imaging effect. The shape of the window 110 can be rectangular, circular, elliptical, etc., depending on the actual situation. This embodiment uses a rectangular window 110 as an example for illustration.

[0023] Reference Figure 3 and Figure 5 The slide holder 200 is used to hold slides. Specifically, the slide holder 200 includes a first mounting position 210 and a second mounting position 220. The first mounting position 210 is used to hold a first slide 211, and the second mounting position 220 is used to hold a second slide 221. It is understood that in some embodiments, the first slide 211 can be a white slide (full-spectrum filter). The white slide can be used for thermal imaging or night vision mode, allowing infrared light (or full-spectrum light) to pass through. Combined with an infrared supplemental lighting device, it allows the device to image through thermal radiation at night or in low-light environments, thus presenting a black-and-white thermal image effect. The second slide 221 can be a red slide (infrared cut-off filter). The red slide can be used for visible light or filtering mode, filtering infrared light and allowing only visible light to pass through, allowing the device to present clear color or white light imaging in well-lit environments such as daytime. In other embodiments, the first slide 211 can be an AR slide (optical glass coated with an anti-reflection film), which can reduce specular reflection and increase the transmittance of light in specific wavelengths (such as infrared). The second glass slide 221 can be an IR glass slide (made of materials such as silicon, germanium, and zinc selenide), which is specifically designed for mid- and long-wave infrared thermal imagers and has high transmittance of infrared light in these wavelength bands. In other embodiments, the first glass slide 211 can be a dichroic mirror or a dichroic mirror (with a special optical coating), which is used for beam splitting or combining, allowing visible light to be reflected and infrared light to be transmitted, for use in multispectral fusion systems. In still some embodiments, the first glass slide 211 and the second glass slide 221 can be made of the same material, but with different thicknesses to achieve different optical imaging effects. This application uses a white glass slide 211 and a red glass slide 221 as an example for illustration.

[0024] To facilitate the description and understanding of the relative arrangement direction of the first slide 211 and the second slide 221, a first direction X is defined. The first mounting position 210 and the second mounting position 220 are arranged relative to each other along the first direction X, as shown in the reference. Figure 5The orientation, that is, the first mounting position 210 and the second mounting position 220 are arranged opposite each other in the left-right direction. The slide holder 200 is movably connected to the base 100 and has a first position and a second position relative to the base 100. (See reference...) Figure 5 and Figure 11 In the first position, the first glass slide 211 covers the window 110, meaning the first glass slide 211 can perform normal light filtering operations. (Refer to...) Figure 8 and Figure 12 In the second position, the second glass slide 221 covers the window 110, meaning that the second glass slide 221 can perform normal light filtering operations.

[0025] Reference Figure 5 , Figures 7 to 12 The linkage mechanism 300 is used to drive the slide holder 200 to move relative to the base 100. Specifically, the linkage mechanism 300 includes a first rod 310 and a second rod 320. The first rod 310 is rotatably connected to the base 100, and the second rod 320 is rotatably connected to the base 100. One end of the second rod 320 is movably connected to the first rod 310, and the other end is movably connected to the slide holder 200. During the rotation of the first rod 310, the second rod 320 can be driven to rotate. For example, refer to... Figure 5 In terms of orientation, when the first rod 310 rotates clockwise, the second rod 320 is driven by the first rod 310 to rotate counterclockwise. That is, the second rod 320 can drive the slide holder 200 to switch from the first position to the second position along the first direction X, so as to realize the normal slide switching operation from the first slide 211 to the second slide 221 and meet the slide usage needs in different scenarios.

[0026] Reference Figure 3 , Figures 8 to 12 The limiting structure 400 is used to limit the linkage mechanism 300. Specifically, the limiting structure 400 is connected to the base 100 and is used to limit the rotation angle of the first rod 310. When the slide holder 200 is in the second position, that is, when the second slide 221 covers the window 110, the limiting structure 400 can cooperate with the linkage mechanism 300 to achieve self-locking, thereby limiting the slide holder 200 from switching from the second position to the first position in the opposite direction of the first direction X. Figure 9 Orientation, that is, it can restrict the slide holder 200 to move in the direction from left to right, so that the slide holder 200 is stably maintained in the second position.

[0027] In the technical solution of this invention, the slide switching assembly 10 includes a base 100, a slide holder 200, a linkage mechanism 300, and a limiting structure 400. The base 100 is provided with a window 110. The slide holder 200 includes a first mounting position 210 and a second mounting position 220 arranged along a first direction X. The first mounting position 210 is used to load a first slide 211, and the second mounting position 220 is used to load a second slide 221. The slide holder 200 is movably connected to the base 100 and has a first position and a second position relative to the base 100. In the first position, the first slide 211 is located in the window 110, and in the second position, the second slide 221 is located in the window 110. The first rod 310 and the second rod 320 of the linkage mechanism 300 are both rotatably connected to the base 100. One end of the second rod 320 is movably connected to the first rod 310, and the other end is movably connected to the slide holder 200. When the first rod 310 is driven to rotate, it can drive the second rod 320 to rotate, thereby driving the slide holder 200 to switch from a first position to a second position along the first direction X to achieve slide switching. In the prior art, when the vehicle (drone, military vehicle, etc.) is in firing mode, a strong recoil force is generated, which drives the slide holder to change position and causes the slide to switch unexpectedly. The limiting structure 400 of this solution can limit the rotation position of the first rod 310, and when the slide holder 200 is in the second position, the limiting structure 400 can cooperate with the linkage mechanism 300 to achieve self-locking, so as to limit the slide holder 200 to switch from the second position to the first position in the opposite direction of the first direction X. That is, the slide switching component 10 of this solution can only drive the second rod 320 through the first rod 310, and then drive the slide holder 200 to switch positions, avoiding the situation where the slide holder 200 is affected by the recoil vibration and drives the linkage mechanism 300 in the opposite direction. Therefore, this solution can keep the target slide stably in the position of window 110, effectively reducing the situation where the slide holder 200 is switched due to recoil and the slide is accidentally replaced, greatly improving the stability of imaging and ensuring the reliability of the optoelectronic observation and aiming device 1 in complex combat environments.

[0028] In some embodiments, the rotation of the first rod 310 can drive the second rod 320 to rotate. For example, referring to… Figure 9 Orientation: When the first rod 310 rotates counterclockwise, the second rod 320, driven by the first rod 310, can rotate clockwise, that is, the second rod 320 can drive the slide holder 200 in the opposite direction of the first direction X (refer to...). Figure 9 The orientation (i.e., the direction from left to right) is switched from the second position to the first position, realizing the normal slide switching operation from the second slide 221 to the first slide 211.

[0029] Reference Figure 5 and Figure 11When the slide holder 200 is in the first position, i.e., the first slide 211 covers the window 110, the limiting structure 400 can cooperate with the linkage mechanism 300 to achieve self-locking, thereby restricting the slide holder 200 from switching from the first position to the second position along the first direction X, as shown in the reference. Figure 5 Orientation, that is, it can restrict the slide holder 200 from switching from the first position to the second position in the direction from left to right, so that the slide holder 200 is stably maintained in the first position.

[0030] The linkage mechanism 300 of this solution can drive the slide holder 200 to move in both directions, which can meet the slide switching needs in various scenarios. Moreover, regardless of whether the linkage mechanism 300 drives the slide holder 200 to the first position or the second position, the limiting structure 400 can cooperate with the linkage mechanism 300 to achieve self-locking, so that the target slide is kept in the window 110 position. This effectively reduces the situation where the slide holder 200 is affected by recoil and the slide is accidentally replaced, which greatly improves the stability of imaging and ensures the reliability of the optoelectronic observation and aiming device 1 in complex combat environments.

[0031] Reference Figure 3 and Figure 7 The following describes the specific limiting settings of the limiting structure 400 on the linkage mechanism 300. In some embodiments, the limiting structure 400 includes a first limiting hole 410, which can be an arc-shaped hole. A first connecting portion 311 is provided on the side of the first rod 310 facing the limiting structure 400. The first connecting portion 311 passes through the first limiting hole 410, meaning the first limiting hole 410 can limit the rotation angle or rotation range of the first rod 310. (Refer to...) Figure 8 and Figure 9 When the slide holder 200 is in the second position, i.e., when the second slide 221 covers the window 110, the arrangement direction of the first rod 310 is perpendicular to the arrangement direction of the second rod 320, and the first connecting portion 311 abuts against the inner wall 411 of the first limiting hole 410, i.e., the first limiting hole 410 can cooperate with the linkage mechanism 300 to achieve self-locking. In other embodiments, refer to Figure 5 When the slide holder 200 is in the first position, i.e., when the first slide 211 covers the window 110, the arrangement direction of the first rod 310 is perpendicular to the arrangement direction of the second rod 320, and the first connecting part 311 abuts against the inner wall 411 of the first limiting hole 410, i.e., the first limiting hole 410 can cooperate with the linkage mechanism 300 to achieve self-locking. Therefore, the slide switching assembly 10 of this solution can only drive the second rod 320 through the first rod 310, and thus drive the slide holder 200 to switch positions, and cannot drive the second rod 320 and the first rod 310 to rotate in the opposite direction through the slide holder 200. This can effectively avoid the slide holder 200 from accidentally switching positions due to recoil, ensuring the stability and reliability of imaging.

[0032] Reference Figures 3 to 6 The specific rotational arrangement of the linkage mechanism 300 and the base 100 is described below. In some embodiments, the limiting structure 400 includes a second limiting hole 420, which communicates with the first limiting hole 410, facilitating the machining of the limiting structure 400. The base 100 is provided with a first rotating shaft 120, and the second rod 320 is provided with a first connecting hole 321. The first rotating shaft 120 of the base 100 passes through the first connecting hole 321 of the second rod 320 and is also inserted into the second limiting hole 420 of the limiting structure 400. In this design, the first rotating shaft 120 simultaneously passes through both the second rod 320 and the limiting structure 400, thereby improving the stability and reliability of the rotational connection between the second rod 320 and the base 100. In other embodiments, the base 100 is provided with a second rotating shaft, which passes through the mounting hole of the first rod 310, allowing the first rod 310 to be rotatably connected to the base 100.

[0033] Reference Figure 3 and Figure 6 The following describes the specific arrangement of the second rod 320 movably connecting to the first rod 310. In some embodiments, the second rod 320 is provided with a second connecting hole 322, which can be an elongated hole. The first connecting part 311 passes through the second connecting hole 322 and is disposed within the first limiting hole 410, thereby enabling the limiting structure 400 to limit the rotation of the first rod 310 and ensuring the reliability of the movable connection between the first rod 310 and the second rod 320. During the process of the first rod 310 being driven to rotate, the first connecting part 311 can move along the extension direction of the second connecting hole 322 to drive the second rod 320 to rotate, thereby realizing the position switching of the slide holder 200. In other embodiments, the first rod 310 is provided with a connecting hole, and the second rod 320 is provided with a connecting part. The connecting part of the second rod 320 can be disposed within the connecting hole of the first rod 310, so that the second rod 320 is movably connected to the first rod 310. This application embodiment takes the example of the first connecting part 311 of the first rod 310 being movably connected to the second connecting hole 322 of the second rod 320 for illustration.

[0034] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8The following describes the specific arrangement of the second rod 320 movably connecting to the slide holder 200. In some embodiments, the slide holder 200 is provided with a third connecting hole 230, which can be an elongated hole. A second connecting portion 323 is provided on the side of the second rod 320 facing the slide holder 200, and the second connecting portion 323 extends toward the slide holder 200. The second connecting portion 323 passes through the third connecting hole 230. During the rotation of the second rod 320 driven by the first rod 310, the second connecting portion 323 can move along the extension direction of the third connecting hole 230 to drive the slide holder 200 to move relative to the base 100, thereby achieving position switching. In other embodiments, the slide holder 200 is provided with a connecting portion, and the second rod 320 is provided with a connecting hole, with the connecting portion of the slide holder 200 passing through the connecting hole of the second rod 320. During the rotation of the second rod 320 driven by the first rod 310, the connecting part of the slide holder 200 can move within the connecting hole of the second rod 320, thereby moving the slide holder 200 relative to the base 100 and achieving position switching. This embodiment of the application uses the example of the second connecting part 323 of the second rod 320 being movably connected to the third connecting hole 230 of the slide holder 200 for illustration.

[0035] The specific structural configuration of the base 100 is described below. In some embodiments, along the first direction X, the base 100 has a first groove 130 on the side facing the linkage mechanism 300, as shown in the figure. Figure 3 In terms of orientation, specifically along the left-right direction, a first groove 130 is provided on the right side of the base 100. The first groove 130 can accommodate the structure and rotation range arrangement of the second rod 320. When the slide holder 200 is in the first position, i.e., when the first slide 211 covers the window 110, the end of the second rod 320 facing away from the first rod 310 is accommodated in the first groove 130. The specific structural dimensions of the first groove 130 can be determined according to the actual situation. This solution, by partially accommodating the second rod 320 in the first groove 130, can fully utilize the space of the base 100 along the first direction X, optimize the spatial structure layout of the base 100, effectively reduce the overall space occupied by the slide switching assembly 10, save material costs of the base 100, and the first groove 130 can also limit the rotation range of the second rod 320, ensuring the reliability of the rotation of the second rod 320.

[0036] In other embodiments, a second groove 140 is provided on the side of the base 100 facing the linkage mechanism 300 along the first direction X, as shown in the figure. Figure 3In terms of orientation, i.e., along the left-right direction, a second groove 140 is provided on the right side of the base 100. The second groove 140 can be spaced apart from the first groove 130, and the second groove 140 can be adapted to the structure and rotation range arrangement of the second rod 320. When the slide holder 200 is in the second position, i.e., when the second slide 221 covers the window 110, the end of the second rod 320 facing the first rod 310 is accommodated in the second groove 140. The specific structural dimensions of the second groove 140 can be determined according to the actual situation. This solution, by accommodating part of the second rod 320 in the first groove 130, can fully utilize the space of the base 100 along the first direction X, optimize the spatial structure layout of the base 100, effectively reduce the overall space occupied by the slide switching assembly 10, save the material cost of the base 100, and the first groove 130 can also limit the rotation range of the second rod 320, ensuring the reliability of the rotation of the second rod 320.

[0037] Reference Figure 6 The contact arrangement between the second rod 320 and the limiting structure 400 is described below. In some embodiments, the second rod 320 is provided with a first protrusion 324, which abuts against the limiting structure 400. In other embodiments, a single first protrusion 324 may be provided. In other embodiments, multiple first protrusions 324 may also be provided; this application embodiment uses a single first protrusion 324 as an example for explanation. The first protrusion 324 is provided on the side of the second rod 320 opposite to the first rod 310, and the first protrusion 324 may extend in the direction toward the limiting structure 400, with its specific extension height depending on the actual situation. It is understood that the base 100 may be provided with a recessed platform to jointly support the limiting structure 400 with the first protrusion 324. The first protrusion 324 of this design can abut against the limiting structure 400, which can significantly reduce the contact area between the second rod 320 and the limiting structure 400, reduce the frictional resistance of the second rod 320 rotating relative to the limiting structure 400, and improve the smoothness of the position switching of the slide holder 200.

[0038] Reference Figures 3 to 5The specific connection arrangement between the limiting structure 400 and the base 100 is described below. In some embodiments, the base 100 is provided with a locking block 150 on its periphery. The locking block 150 can be single or multiple. This embodiment uses multiple locking blocks 150 as an example. The limiting structure 400 is provided with a locking groove 430, the structure and number of which can be adapted to the arrangement of the locking blocks 150 on the base 100. The locking blocks 150 of the base 100 can be engaged with the locking grooves 430 of the limiting structure 400. In other embodiments, the base 100 is provided with a locking groove 430 on its periphery, and the limiting structure 400 is provided with a locking block 150, which is engaged within the locking grooves 430 of the base 100. This embodiment uses the engagement of the locking blocks 150 of the base 100 with the locking grooves 430 of the limiting structure 400 as an example. The assembly operation of the base 100 and the limiting structure 400 in this solution is convenient and quick, and can ensure the stability and reliability of the snap-fit.

[0039] Reference Figures 3 to 8 The specific connection structure between the slide holder 200 and the base 100 is described below. In some embodiments, the base 100 is provided with a groove 180 extending along the first direction X, and the slide holder 200 passes through the groove 180. The linkage mechanism 300 can drive the slide holder 200 to slide relative to the base 100 to achieve position switching, making the overall switching operation convenient and quick. Specifically, the base 100 may be provided with two protruding ribs 160, each of which extends along the first direction X. It can be understood that the two protruding ribs 160 are arranged at intervals along the second direction Y, and the second direction Y is perpendicular to the first direction X, referring to... Figure 8 The orientation can be either left or right (X) or up or down (Y). The sidewall of the base 100 can be provided with multiple protrusions 170, which, together with multiple ribs 160, define a groove 180 for the slide holder 200 to pass through. This design effectively reduces the sliding resistance between the slide holder 200 and the base 100. In other embodiments, the sidewall of the base 100 can have a groove for the slide holder 200 to pass through. This embodiment uses the protrusions 170 and ribs 160 defining the groove 180 as an example for illustration.

[0040] Reference Figure 6 In some embodiments, a magnetic ring 312 is sleeved on the outer periphery of the first connecting part 311. Compared with the solution where the first connecting part 311 is slidably connected to the second connecting hole 322, this solution can achieve rolling connection of the first connecting part 311 within the second connecting hole 322 by setting the magnetic ring 312, which can effectively reduce wear and extend the service life of the linkage mechanism 300.

[0041] It should be noted that the first protrusion 324 is provided with a magnetic part 3241, which includes a first N pole 3242 and a first S pole 3243. The magnetic ring 312 includes a second N pole 3121 and a second S pole 3122. When the slide holder 200 is in the first position, that is, when the first slide 211 covers the window 110, the first N pole 3242 magnetically attracts the second S pole 3122. That is, the first protrusion 324 of the second rod 320 can magnetically attract the first connecting part 311 of the first rod 310, thus effectively suppressing the second rod 320 from driving the first rod 310 to rotate, and further avoiding the situation where the slide holder 200 is affected by the recoil vibration and drives the linkage mechanism 300 in the opposite direction. This solution can keep the first slide 211 stably in the position of the window 110, greatly improving the stability and reliability of imaging.

[0042] During the transition of the slide holder 200 from the first position to the second position, the magnetic part 3241 can drive the magnetic ring 312 to rotate, effectively preventing magnetic repulsion between the first N pole 3242 of the first rod 310 and the second N pole 3121 of the second rod 320 when in the second position. (Refer to...) Figure 10 When the slide holder 200 is in the second position, that is, when the second slide 221 covers the window 110, the first N pole 3242 magnetically attracts the second S pole 3122, so that the first protrusion 324 of the second rod 320 can magnetically attract the first connecting part 311 of the first rod 310, further avoiding the situation where the slide holder 200 is affected by the recoil vibration and reverse drives the linkage mechanism 300. This solution can keep the second slide 221 stably in the window 110 position, greatly improving the stability and reliability of imaging.

[0043] Reference Figures 1 to 3 A second aspect of this invention provides a photoelectric viewing device 1, which includes a slide switching assembly 10 and a driving unit 20 as described in the above embodiments. The driving unit 20 is connected to a first rod 310 and can drive the first rod 310 to rotate, thereby causing a second rod 320 to rotate and the slide holder 200 to move relative to the base 100 to achieve position switching. It should be noted that the driving unit 20 can electrically drive the first rod 310 to rotate or magnetically drive the first rod 310 to rotate. This embodiment of the application uses the example of the driving unit 20 electrically driving the first rod 310 to rotate.

[0044] The limiting structure 400 of this solution can restrict the rotational position of the first rod 310. When the slide holder 200 is in the second position, the limiting structure 400 can cooperate with the linkage mechanism 300 to achieve self-locking, thereby restricting the slide holder 200 from switching from the second position to the first position in the reverse direction X. That is, the slide switching component 10 of this solution can only drive the second rod 320 through the first rod 310, and then drive the slide holder 200 to switch positions, avoiding the situation where the slide holder 200 is affected by recoil vibration and drives the linkage mechanism 300 in the opposite direction. Therefore, this solution can keep the target slide stably in the window 110 position, effectively reducing the situation where the slide holder 200 is affected by recoil and switches positions, resulting in accidental slide replacement, greatly improving the stability of imaging, and ensuring the reliability of the optoelectronic observation and aiming device 1 in complex combat environments.

[0045] Reference Figures 1 to 3 In some embodiments, the slide switching assembly 10 includes a cover 500 for covering the slide holder 200. In other embodiments, the cover 500 can be snapped onto the base 100. In still other embodiments, the cover 500 can be threaded onto the base 100; this embodiment uses the snap-fit ​​connection of the cover 500 to the base 100 as an example. It is understood that the photoelectric viewing device 1 may include a wire assembly 30 for supplying power to the viewing device.

[0046] The following describes the specific operation process of the glass slide switching component 10 in an embodiment of the photoelectric observation and aiming device 1 of this application. (Refer to...) Figure 3 , Figure 5 and Figure 11 When the slide holder 200 is in the first position relative to the base 100, that is, when the first slide 211 covers the window 110 of the base 100, the arrangement direction of the first rod 310 in the linkage mechanism 300 is perpendicular to the arrangement direction of the second rod 320, and the first connecting part 311 of the first rod 310 abuts against the inner wall 411 of the first limiting hole 410 in the limiting structure 400. That is, the limiting structure 400 can cooperate with the linkage mechanism 300 to achieve self-locking, so as to avoid the slide holder 200 being affected by the recoil force and driving the linkage mechanism 300 in the opposite direction, so that the slide holder 200 can be stably maintained in the first position.

[0047] Reference Figures 5 to 9 When the slide holder 200 needs to switch from the first position to the second position, the drive unit 20 can break the self-locking state, that is, the drive unit 20 can normally drive the first rod 310 to rotate in the clockwise direction, the first rod 310 drives the second rod 320 to rotate in the counterclockwise direction, and the second rod 320 drives the slide holder 200 to switch from the first position to the second position in the first direction X.

[0048] Reference Figure 9 and Figure 12When the slide holder 200 is switched to the second position, the arrangement direction of the first rod 310 in the linkage mechanism 300 is perpendicular to the arrangement direction of the second rod 320, and the first connecting part 311 of the first rod 310 abuts against the inner wall 411 of the first limiting hole 410 in the limiting structure 400. That is, the limiting structure 400 can cooperate with the linkage mechanism 300 to achieve self-locking again, so as to avoid the slide holder 200 being affected by the recoil force and driving the linkage mechanism 300 in the opposite direction, so that the slide holder 200 can be stably maintained in the second position.

[0049] Reference Figures 5 to 9 When the slide holder 200 needs to switch from the second position to the first position, the drive unit 20 can break the self-locking state, that is, the drive unit 20 can normally drive the first rod 310 to rotate in the counterclockwise direction, the first rod 310 drives the second rod 320 to rotate in the clockwise direction, and the second rod 320 drives the slide holder 200 to switch from the second position to the first position in the opposite direction of the first direction X.

[0050] It should be noted that if directional indications (such as up, down, left, right, front, back, etc.) are involved in the embodiments of the present invention, these directional indications are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly. When a direction reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the direction reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.

[0051] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0052] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
