When the transmission switching component is switched to the first position, it is drivenly connected between the focusing operation component and the first transmission mechanism, allowing the focusing operation component to adjust the position of the first lens or the first camera movement via the first transmission mechanism. When the transmission switching component is switched to the second position, it is drivenly connected between the focusing operation component and the second transmission mechanism, allowing the focusing operation component to adjust the position of the second lens or the second camera movement via the second transmission mechanism. A detection component is used to detect the position of the transmission switching component; A display, communicatively connected to the detection component, is used to display an image captured by the first lens component when the detection component detects that the transmission switching component has switched to the first position, and to display an image captured by the second lens component when the detection component detects that the transmission switching component has switched to the second position.

Detailed Implementation

[0008] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0009] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0010] The binocular observation device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0011] refer to Figures 1-21 The binocular observation device provided in this application embodiment may include a first lens assembly 200, a second lens assembly 300, a focusing operation component 900, a first transmission mechanism 1700, a second transmission mechanism 1800, a transmission switching component 800, a detection component 1300, and a display (not shown in the figure).

[0012] The first lens assembly 200 and the second lens assembly 300 can be of different types. This allows the binocular observation device to achieve different imaging functions. For example, one of the first lens assembly 200 and the second lens assembly 300 can be a visible light lens assembly, and the other can be an infrared light lens assembly; or, their focusing parameters can be different. Figure 4As shown, the first lens assembly 200 may include a first lens 210 and a first mechanism 220. The first lens 210 and the first mechanism 220 may be arranged sequentially along the incident direction of light so that the light collected by the first lens 210 can be transmitted to the first mechanism 220. The second lens assembly 300 may include a second lens 310 and a second mechanism 320. The second lens 310 and the second mechanism 320 may be arranged sequentially along the incident direction of light so that the light collected by the second lens 310 can be transmitted to the second mechanism 320. In this embodiment, both the first mechanism 220 and the second mechanism 320 may include an image sensor. The image sensor can be used to convert the received light signal into an electrical signal and can transmit the electrical signal to the circuit board 1200 described below.

[0013] The first transmission mechanism 1700 can be connected to the first lens 210 or the first camera module 220. By driving the first transmission mechanism 1700 to move, the first lens 210 or the first camera module 220 can be moved to adjust the distance between the first lens 210 and the first camera module 220. The second transmission mechanism 1800 can be connected to the second lens 310 or the second camera module 320. By driving the second transmission mechanism 1800 to move, the second lens 310 or the second camera module 320 can be moved to adjust the distance between the second lens 310 and the second camera module 320.

[0014] The transmission switching assembly 800 can switch between a first position and a second position. Switching the transmission switching assembly 800 to the first position connects it to the focusing operation member 900 and the first transmission mechanism 1700. The focusing operation member 900 then adjusts the position of the first lens 210 or the first camera module 220 via the first transmission mechanism 1700, thereby adjusting the distance between the first lens 210 and the first camera module 220, and thus achieving focal length adjustment of the first lens assembly 200. Switching the transmission switching assembly 800 to the second position connects it to the focusing operation member 900 and the second transmission mechanism 1800. The focusing operation member 900 then adjusts the position of the second lens 310 or the second camera module 320 via the second transmission mechanism 1800, thereby adjusting the distance between the second lens 310 and the second camera module 320, and thus achieving focal length adjustment of the second lens assembly 300. With this configuration, by switching the position of the transmission switching component 800, the focusing operation component 900 can be connected to the first lens assembly 200 and the second lens assembly 300 independently, so that when the focusing operation component 900 performs a focusing operation, it can only adjust the focal length of the first lens assembly 200 or the second lens assembly 300 individually.

[0015] The detection component 1300 can be used to detect the position of the transmission switching component 800; the display can be communicatively connected to the detection component 1300, and the display can be used to display the image captured by the first lens component 200 when the detection component 1300 detects that the transmission switching component 800 has switched to the first position, and can be used to display the image captured by the second lens component 300 when the detection component 1300 detects that the transmission switching component 800 has switched to the second position.

[0016] This configuration allows the display to automatically show the image captured by the first lens assembly 200 when the detection component 1300 detects that the transmission switching component 800 has switched to the first position, and automatically show the image captured by the second lens assembly 300 when the detection component 1300 detects that the transmission switching component 800 has switched to the second position. This achieves automatic matching between the display output and the lens, effectively simplifying operation, improving the ease of use of the binocular observation equipment, and reducing the user's workload. Furthermore, the communication connection between the detection component 1300 and the display allows for rapid mode switching, facilitating the display of images at crucial moments and improving the working efficiency of the binocular observation equipment. In addition, because the display switches modes the instant the detection component 1300 detects that the transmission switching component 800 has switched to the first or second position, the user can observe the focusing process on the display when focusing the first lens assembly 200 or the second lens assembly 300 using the focusing operation component 900, making it easier to adjust the first lens assembly 200 or the second lens assembly 300 to the desired focal length.

[0017] In this embodiment, the display may include a first display screen (not shown) and a second display screen (not shown). The first display screen may be opposite to the first lens assembly 200, and the second display screen may be opposite to the second lens assembly 300. Both the first and second display screens are communicatively connected to the detection assembly 1300. When the detection assembly 1300 detects that the transmission switching assembly 800 has switched to a first position, both the first and second display screens display the image captured by the first lens assembly 200. When the detection assembly 1300 detects that the transmission switching assembly 800 has switched to a second position, both the first and second display screens display the image captured by the second lens assembly 300. For example, both the first and second display screens may be OLED screens.

[0018] Optionally, such as Figure 1As shown, the binocular observation device may further include a first eyepiece 400 and a second eyepiece 500. The first eyepiece 400 may be opposite to the first lens assembly 200, and the first display screen may be located between the first eyepiece 400 and the first lens assembly 200. The second eyepiece 500 may be opposite to the second lens assembly 300, and the second display screen may be located between the second eyepiece 500 and the second lens assembly 300. With this configuration, the first eyepiece 400 and the second eyepiece 500 can respectively magnify the images displayed on the first and second display screens for user viewing.

[0019] In an optional embodiment, the transmission switching assembly 800 may include a user operating component and a transmission switching component 820 transmissionally connected to the user operating component. The user operating component can be used to drive the transmission switching component 820 to switch between a first position and a second position. When the transmission switching component 820 is in the first position, the transmission switching component 820 is transmissionally connected between the focusing operating component 900 and the first transmission mechanism 1700 to achieve transmission connection between the focusing operating component 900 and the first transmission mechanism 1700. In this way, operating the focusing operating component 900 can drive the first lens 210 or the first camera movement 220 to move through the first transmission mechanism 1700 to adjust the distance between the first lens 210 and the first camera movement 220. When the transmission switching component 820 is in the second position, the transmission switching component 820 is transmissionally connected between the focusing operating component 900 and the second transmission mechanism 1800. In this way, operating the focusing operating component 900 can drive the second lens 310 or the second camera movement 320 to move through the second transmission mechanism 1800 to adjust the distance between the second lens 310 and the second camera movement 320.

[0020] The detection component 1300 can be used to detect the position of the user operation component or the transmission switching component 820.

[0021] In one embodiment, the detection component 1300 can be used to detect the angle or position of a user-operated component.

[0022] Optionally, the user operating component can be rotatably mounted on the housing 100 of the binocular observation device. Rotating the user operating component can drive the transmission switching component 820 to move. The user operating component can rotate between a first angle and a second angle. When the user operating component rotates to the first angle, it drives the transmission switching component 820 to move to a first position; when the user operating component rotates to the second angle, it drives the transmission switching component 820 to move to a second position. Of course, the user operating component can also be mounted on the housing 100 without rotation. For example, the user operating component can be movably mounted on the housing 100, and the transmission switching component 820 can be moved by moving the user operating component.

[0023] In one embodiment, the detection component 1300 may include an angle encoder, which may be coaxially arranged with and fixedly connected to the user operating component. The angle encoder may be used to detect the angle of the user operating component. When the angle encoder detects that the user operating component has rotated to a first angle, the display shows an image captured by the first lens component 200; when the angle encoder detects that the user operating component has rotated to a second angle, the display shows an image captured by the second lens component 300.

[0024] In another embodiment, the detection component 1300 may include a first magnetic element, a second magnetic element, and a Hall sensor. The first and second magnetic elements may be disposed on the housing 100 and spaced apart along the rotation direction of the user operating component. The Hall sensor is disposed on the user operating component. When the user operating component rotates to a first angle, the Hall sensor is opposite to the first magnetic element. At this time, the Hall sensor detects the first magnetic element and sends a signal to the display indicating that the user operating component has rotated to the first angle, causing the display to show the image captured by the first lens assembly 200. When the user operating component rotates to a second angle, the Hall sensor is opposite to the second magnetic element. At this time, the Hall sensor detects the second magnetic element and sends a signal to the display indicating that the user operating component has rotated to the second angle, causing the display to show the image captured by the second lens assembly 300.

[0025] In another embodiment, the detection component 1300 may also include a laser emitter, a first laser receiver, and a second laser receiver. The laser emitter is disposed on the user operating device, and the first and second laser receivers are disposed on the housing 100. When the user operating device is rotated to a first angle, the laser emitter and the first laser receiver are opposite each other. At this time, the first laser receiver receives the laser emitted by the laser emitter and sends a signal to the display that the user operating device has rotated to the first angle, so that the display shows the image captured by the first lens assembly 200. When the user operating device is rotated to a second angle, the laser emitter and the second laser receiver are opposite each other. At this time, the second laser receiver receives the laser emitted by the laser emitter and sends a signal to the display that the user operating device has rotated to the second angle, so that the display shows the image captured by the second lens assembly 300.

[0026] The detection component 1300 may also include a first micro switch and a second micro switch disposed on the housing 100. The user operating component may be provided with a trigger protrusion. When the user operating component is rotated to a first angle, the trigger protrusion triggers the first micro switch. At this time, the first micro switch sends a signal to the display that the user operating component has rotated to the first angle, so that the display shows the image captured by the first lens assembly 200. When the user operating component is rotated to a second angle, the trigger protrusion triggers the second micro switch. At this time, the second micro switch sends a signal to the display that the user operating component has rotated to the second angle, so that the display shows the image captured by the second lens assembly 300.

[0027] Of course, the detection component 1300 may also include other structures capable of detecting the rotation angle of the user's operating component, which can be set according to actual needs.

[0028] In all the above methods of detecting the angle of the user operating component, the detection component 1300 needs to be set close to or on the user operating component. However, since the circuit board 1200 is set inside the housing 100, these detection methods are prone to resulting in a long connecting wire between the circuit board 1200 and the detection component 1300, which occupies a lot of space and is prone to interference with other components.

[0029] In another embodiment, the detection component 1300 can be used to detect the position of the transmission switching component 820. Since the transmission switching component 820 is disposed within the housing 100, the detection component 1300 can be arranged within the internal space of the housing 100 without needing to be located close to the user operating components, thus facilitating the placement of the detection component 1300. Furthermore, since the circuit board 1200 is disposed within the housing 100, placing the detection component 1300 within the internal space of the housing 100 allows the detection component 1300 to be closer to the circuit board 1200, making the structure of the binocular observation device more compact and reducing the length of the connecting wires between the detection component 1300 and the circuit board 1200, thereby reducing the space occupied by the connecting wires.

[0030] In one embodiment, the detection component 1300 may include a position sensor, which may be disposed on the transmission switching member 820 and used to detect the position of the transmission switching member 820.

[0031] Alternatively, the detection component 1300 may include a distance sensor, which may be disposed on the transmission switch 820 and used to detect the distance between the transmission switch 820 and the user operation component.

[0032] In another embodiment, the detection component 1300 may include a first magnetic element, a second magnetic element, and a Hall sensor. The first and second magnetic elements may be disposed on the housing 100 and spaced apart along the moving direction of the transmission switching component 820. The Hall sensor is disposed on the transmission switching component 820. When the transmission switching component 820 moves to a first position, the Hall sensor is opposite to the first magnetic element. At this time, the Hall sensor detects the first magnetic element and sends a signal to the display that the transmission switching component 820 has moved to the first position, causing the display to show the image captured by the first lens assembly 200. When the transmission switching component 820 moves to a second position, the Hall sensor is opposite to the second magnetic element. At this time, the Hall sensor detects the second magnetic element and sends a signal to the display that the transmission switching component 820 has moved to the second position, causing the display to show the image captured by the second lens assembly 300.

[0033] In another embodiment, the detection component 1300 may also include a laser emitter, a first laser receiver, and a second laser receiver. The first and second laser receivers are disposed within the housing 100 and spaced apart along the moving direction of the transmission switching member 820. The laser emitter is disposed on the transmission switching member 820. When the transmission switching member 820 moves to the first position, the laser emitter is opposite to the first laser receiver. At this time, the first laser receiver receives the laser emitted by the laser emitter and sends a signal to the display that the transmission switching member 820 has moved to the first position, causing the display to show the image captured by the first lens assembly 200. When the transmission switching member 820 moves to the second position, the laser emitter is opposite to the second laser receiver. At this time, the second laser receiver receives the laser emitted by the laser emitter and sends a signal to the display that the transmission switching member 820 has moved to the second position, causing the display to show the image captured by the second lens assembly 300.

[0034] For example, the first laser receiver and the second laser receiver can be disposed on the circuit board 1200 described below, which can save or shorten the length of the connecting wires between the circuit board 1200 and the first laser receiver and the second laser receiver.

[0035] The detection component 1300 may also include a first micro switch and a second micro switch disposed within the housing 100. The first micro switch and the second micro switch are spaced apart along the moving direction of the transmission switching member 820. The transmission switching member 820 may be provided with a trigger protrusion. When the transmission switching member 820 moves to the first position, the trigger protrusion triggers the first micro switch. At this time, the first micro switch sends a signal to the display that the transmission switching member 820 has moved to the second position, causing the display to display the image captured by the first lens assembly 200. When the transmission switching member 820 moves to the second position, the trigger protrusion triggers the second micro switch. At this time, the second micro switch sends a signal to the display that the transmission switching member 820 has moved to the second position, causing the display to display the image captured by the second lens assembly 300.

[0036] For example, the first micro switch and the second micro switch can be disposed on the circuit board 1200 described below, which can save the connecting wires between the circuit board 1200 and the first micro switch or shorten the length of the connecting wires.

[0037] Of course, the detection component 1300 may also include other structures capable of detecting the position of the transmission switching component 820, which can be set according to actual needs.

[0038] In an optional embodiment, a sensing element 823 may be provided on the transmission switching assembly 800, such as... Figure 4 As shown, the detection component 1300 may include a first detection element 1310 and a second detection element 1320, both of which can be used to detect the sensor 823.

[0039] When the transmission switching assembly 800 switches to the first position, the first detection element 1310 detects the sensing element 823; when the transmission switching assembly 800 switches to the second position, the second detection element 1320 detects the sensing element 823. In this embodiment, when the transmission switching assembly 800 switches to the first position, the first detection element 1310 can accurately detect the sensing element 823, and when the transmission switching assembly 800 switches to the second position, the second detection element 1320 can accurately detect the sensing element 823. This makes the position detection of the transmission switching assembly 800 by the detection assembly 1300 more accurate, avoiding misjudgment of the state due to detection errors. Furthermore, since only two detection elements correspond to two definite positions, compared with the method of position sensor measurement, there is no fuzzy judgment of intermediate transition states, which can improve the accuracy of state detection of the transmission switching assembly 800.

[0040] In other embodiments, the transmission switching component 800 may not have the sensing plate 823, and the detection component 1300 may include a position sensor, which can be used to detect the position of the transmission switching component 800.

[0041] Optionally, the transmission switching assembly 800 may include a toggle member 821 and a sliding drive member 822 connected to the toggle member 821. The toggle member 821 may be connected to a user operating member. Operating the user operating member may drive the toggle member 821 to move between a first position and a second position, thereby causing the sliding drive member 822 to move between the first position and the second position, so that the sliding drive member 822 is connected to the first lens 210 or the first mechanism 220, or to the second lens 310 or the second mechanism 320.

[0042] For example, such as Figure 13 As shown, the sensing element 823 can be disposed on the actuating member 821. The first detection element 1310 and the second detection element 1320 can be distributed along the moving direction of the actuating member 821. When the actuating member 821 moves to the first position, the first detection element 1310 detects the sensing element 823; when the actuating member 821 moves to the second position, the second detection element 1320 detects the sensing element 823. Of course, the sensing element 823 can also be disposed on the sliding drive member 822.

[0043] Optionally, the first detection element 1310 can be a first optocoupler, and the second detection element 1320 can be a second optocoupler. The sensing sheet 823 can be a photosensitive sheet. When the toggle member 821 moves to the first position, the photosensitive sheet extends into the first optocoupler and blocks the light from the first optocoupler, thereby triggering the first optocoupler. At this time, the first optocoupler can send a signal to the display to display the image captured by the first lens assembly 200. When the toggle member 821 moves to the second position, the photosensitive sheet extends into the second optocoupler and blocks the light from the second optocoupler, thereby triggering the second optocoupler. At this time, the second optocoupler can send a signal to the display to display the image captured by the second lens assembly 300.

[0044] In optional embodiments, such as Figures 4-6 , Figures 11-14As shown, the binocular observation device may further include a circuit board 1200, which is electrically connected to the first sensor 220 and the second sensor 320, and is also electrically connected to a display and a detection component 1300. Images acquired by the first sensor 220 and the second sensor 320 can be transmitted to the circuit board 1200 and then to the display for display. Detection signals from the detection component 1300 can be transmitted to the circuit board 1200, which can control the display based on these signals.

[0045] The transmission switching component 820 and the circuit board 1200 can be positioned between the user operating component and the first mechanism 220. The detection component 1300 can be separated from the circuit board 1200, or the detection component 1300 can be mounted on the circuit board 1200. This configuration facilitates the connection between the circuit board 1200 and the first mechanism 220 and the second mechanism 320, effectively shortening the length of the connecting wires, reducing signal attenuation and interference during transmission, and improving the stability and quality of image data transmission from the first mechanism 220 and the second mechanism 320 to the circuit board 1200 and then to the display. Furthermore, since a transmission switching component 820 is provided between the user operating component and the first mechanism 220, the detection component 1300 used to detect the position of the transmission switching component 820 can be close to the circuit board 1200 or placed on the circuit board 1200. This makes the electrical connection between the detection component 1300 and the circuit board 1200 more convenient, and the electrical connection between the detection component 1300 and the circuit board 1200 can be achieved without long connecting wires. On the one hand, this can reduce the complexity of the connecting wire layout and the possible signal interference problems. On the other hand, it can make the internal structure of the binocular observation device more compact, which is conducive to improving the utilization rate of the internal space of the device.

[0046] In this embodiment, both the transmission switching component 820 and the circuit board 1200 can be located within the space between the user operating component and the first mechanism 220. Alternatively, a portion of the transmission switching component 820 and a portion of the circuit board 1200 can be located within the space between the user operating component and the first mechanism 220, while another portion of the transmission switching component 820 and another portion of the circuit board 1200 can be located outside the space between the user operating component and the first mechanism 220. For example, another portion of the transmission switching component 820 and another portion of the circuit board 1200 can extend above or below the first mechanism 220.

[0047] In other embodiments, the transmission switching component 820 and the circuit board 1200 may not be provided between the user operating component and the first mechanism 220, and the detection component 1300 may not be provided on the circuit board 1200. For example, the detection component 1300 may be an angle encoder, which is provided on the user operating component to detect the angle of the user operating component.

[0048] In an optional embodiment, the transmission switching assembly 800 may include a switching knob 810, and the binocular observation device further includes a housing 100. The first lens assembly 200 and the second lens assembly 300 are both connected to the housing 100. The switching knob 810 is rotatably mounted on the housing 100. Rotating the switching knob 810 to a first angle moves the transmission switching component 820 to a first position to adjust the position of the first lens 210 or the first mechanism 220. Rotating the switching knob 810 to a second angle moves the transmission switching component 820 to a second position to adjust the position of the second lens 310 or the second mechanism 320. With this configuration, the user can switch lenses with a simple rotation.

[0049] One of the housing 100 and the switching knob 810 may be provided with a first groove 812 and a second groove 813, and the other may be provided with a limiting part 104. The first groove 812 and the second groove 813 may be distributed at intervals along the circumference of the switching knob 810. When the switching knob 810 is rotated to a first angle, at least a portion of the limiting part 104 is embedded in the first groove 812. When the switching knob 810 is rotated to a second angle, at least a portion of the limiting part 104 is embedded in the second groove 813.

[0050] This design ensures that when the limiting part 104 is inserted into the first groove 812 or the second groove 813, a noticeable clicking sensation and change in resistance are generated, providing clear tactile feedback to the user and allowing them to perceive whether the lens switching is successful. Furthermore, when the limiting part 104 is inserted into the first groove 812 or the second groove 813, the limiting engagement between the limiting part 104 and the first groove 812 or the second groove 813 locks the switching knob 810 at its current angle for a first degree. This prevents the switching knob 810 from changing its angle due to slight impacts or vibrations, making it less prone to accidental triggering and ensuring the binocular observation device remains in the desired mode.

[0051] In other embodiments, the groove and the limiting part 104 may not be provided on the housing 100 and the switching knob 810.

[0052] In an optional embodiment, the limiting part 104 may include an elastic element 1042 and a ball bearing 1041 connected to the elastic element 1042. When the switching knob 810 is rotated to a first angle, the elastic element 1042 drives the ball bearing 1041 to embed into the first groove 812. When the switching knob 810 is rotated to a second angle, the elastic element 1042 drives the ball bearing 1041 to embed into the second groove 813. With this configuration, since the elastic element 1042 has a certain degree of elasticity, when rotating the switching knob 810, the user does not need to apply excessive force to disengage the ball bearing 1041 from the first groove 812 or the second groove 813, thereby facilitating the rotation of the switching knob 810. Furthermore, after the ball bearing 1041 is embedded in the first groove 812 or the second groove 813, due to the constraint effect of the first groove 812 or the second groove 813 on the ball bearing 1041 and the elastic force of the elastic element 1042, the switching knob 810 is effectively locked at the current angle. Unless the user applies sufficient force to overcome the elastic force of the elastic element 1042 and the friction between the ball bearing 1041 and the first groove 812 or the second groove 813, the switching knob 810 will not turn easily, thereby ensuring the stability of the binocular observation device.

[0053] In this embodiment, as Figure 21 As shown, the switching knob 810 may be provided with a first groove 812 and a second groove 813, and the housing 100 may be provided with a limiting part 104. Specifically, the ball 1041 may be connected to the housing 100 through an elastic member 1042.

[0054] In other embodiments, the limiting portion 104 may also include only the ball 1041, or the limiting portion 104 may be a spherical protrusion.

[0055] In an optional embodiment of this application, the first transmission mechanism 1700 may include a first focusing frame 1000 and a first transmission member 1400. The first focusing frame 1000 is connected to the first lens 210 or the first camera module 220. The first transmission member 1400 may be threadedly connected to the first focusing frame 1000. When the transmission switching component 800 is in the first position, the transmission switching component 800 is transmissionally connected between the focusing operation component 900 and the first transmission member 1400. The focusing operation component 900 may drive the first transmission member 1400 to rotate, thereby moving the first focusing frame 1000, which may adjust the position of the first lens 210 or the first camera module 220, thereby adjusting the focal length of the first lens assembly 200.

[0056] The second transmission mechanism 1800 may include a second focusing frame 1100 and a second transmission component 1500. The second focusing frame 1100 may be connected to the second lens 310 or the second camera movement 320. The second transmission component 1500 may be threadedly connected to the second focusing frame 1100. When the transmission switching component 800 is in the second position, the transmission switching component 800 is transmissionally connected between the focusing operation component 900 and the second transmission component 1500. The focusing operation component 900 may drive the second transmission component 1500 to rotate, thereby moving the second focusing frame 1100, which may adjust the position of the second lens 310 or the second camera movement 320, thereby adjusting the focal length of the second lens assembly 300.

[0057] The first focusing frame 1000 and the second focusing frame 1100 can be spaced apart. Specifically, the first focusing frame 1000 and the second focusing frame 1100 can be spaced apart along the moving direction of the sliding drive member 822, and, as shown... Figure 15 and Figure 16 As shown, the first focusing frame 1000 and the second focusing frame 1100 have the same structure.

[0058] In this embodiment, the first focusing frame 1000 and the second focusing frame 1100 have the same structure, which means that the same mold and process can be used in the design and manufacturing of the first focusing frame 1000 and the second focusing frame 1100, which can simplify the production process, improve production efficiency and reduce production costs.

[0059] In other embodiments, the structures of the first focusing frame 1000 and the second focusing frame 1100 may also be different.

[0060] In an optional embodiment, the first focusing frame 1000 may be connected to a first limiting member 1030, and the first limiting member 1030 and the first transmission member 1400 may be in a limiting engagement in the moving direction of the first focusing frame 1000; such as Figure 8 As shown, the second focusing frame 1100 can be connected to a second limiting member 1130. In the moving direction of the second focusing frame 1100, the second limiting member 1130 and the second transmission member 1500 can be limited and engaged.

[0061] In this embodiment, the movement of the first focusing frame 1000 can be limited by the limiting engagement between the first limiting member 1030 and the first transmission member 1400. When the first focusing frame 1000 moves to the position where the first limiting member 1030 and the first transmission member 1400 are engaged, the first transmission member 1400 will prevent the first focusing frame 1000 from moving further, thereby precisely limiting the movement of the first focusing frame 1000. Since the movement of the first focusing frame 1000 directly determines the focal length change of the first lens assembly 200, the focal length range of the first lens assembly 200 can be indirectly limited. Similarly, by limiting the movement of the second focusing frame 1100 through the limiting engagement of the second limiting member 1130 and the second transmission member 1500, the movement of the second focusing frame 1100 can be restricted. When the second focusing frame 1100 moves to the position where the second limiting member 1130 and the second transmission member 1500 are in limiting engagement, the second transmission member 1500 will prevent the second focusing frame 1100 from moving further, thereby precisely limiting the movement of the second focusing frame 1100. Since the movement of the second focusing frame 1100 directly determines the focal length change of the second lens assembly 300, the focal length range of the second lens assembly 300 can be indirectly limited.

[0062] In other embodiments, the first focusing frame 1000 may not be connected to the first limiting member 1030, and the second focusing frame 1100 may not be connected to the second limiting member 1130.

[0063] In optional embodiments, such as Figure 15 As shown, the first focusing frame 1000 may be provided with at least two first mounting holes 1003. The center of each first mounting hole 1003 may be spaced differently from the end face of the first focusing frame 1000 near the first transmission member 1400. The first limiting member 1030 may be selectively connected to one of the first mounting holes 1003. In this embodiment, the different distances between the different first mounting holes 1003 and the end face of the first focusing frame 1000 near the first transmission member 1400 mean that the travel distance of the first focusing frame 1000 is different when the first limiting member 1030 is connected to different first mounting holes 1003. Since the movement of the first focusing frame 1000 directly determines the focal length change of the first lens assembly 200, by selecting different first mounting holes 1003 to install the first limiting member 1030, the adjustment range of the focal length of the first lens assembly 200 can be expanded, so that the first lens assembly 200 can meet the needs of different focal lengths.

[0064] Of course, the first focusing frame 1000 can also have only one first mounting hole 1003.

[0065] like Figure 16As shown, the second focusing frame 1100 may be provided with at least two second mounting holes 1103. The center of each second mounting hole 1103 may have different distances from the end face of the second focusing frame 1100 near the second transmission member 1500. The second limiting member 1130 may be selectively connected to one of the second mounting holes 1103. In this embodiment, the different distances between the different second mounting holes 1103 and the end face of the second focusing frame 1100 near the second transmission member 1500 mean that when the second limiting member 1130 is connected to different second mounting holes 1103, the travel distance of the second focusing frame 1100 is different. Since the movement of the second focusing frame 1100 directly determines the focal length change of the second lens assembly 300, by selecting different second mounting holes 1103 to install the second limiting member 1130, the adjustment range of the focal length of the second lens assembly 300 can be expanded, so that the second lens assembly 300 can meet the needs of different focal lengths.

[0066] Of course, the second focusing frame 1100 may also have only one second mounting hole 1103.

[0067] In optional embodiments, such as Figure 15 As shown, the first focusing frame 1000 may include a first frame 1001 and a first connecting arm 1002 arranged radially along the first frame 1001. The first connecting arm 1002 can be connected to the first frame 1001, the first frame 1001 can be threadedly connected to the first transmission member 1400, and the first connecting arm 1002 can be connected to the first lens 210 or the first mechanism 220. Specifically, the first connecting arm 1002 can be connected to the first adapter 1010 described below. Figure 16 As shown, the second focusing frame 1100 may include a second frame 1101 and a second connecting arm 1102 arranged radially along the second frame 1101. The second connecting arm 1102 may be connected to the second frame 1101. The second frame 1101 may be threadedly connected to the second transmission member 1500. The second connecting arm 1102 may be connected to the second lens 310 or the second mechanism 320. Specifically, the second connecting arm 1102 may be connected to the second adapter 1110 described below.

[0068] Here, the first frame 1001 may be provided with a first mounting hole 1003, and the second frame 1101 may be provided with a second mounting hole 1103. The first connecting arm 1002 may be provided with a first guide hole 1004 as described below, and the second connecting arm 1102 may be provided with a second guide hole 1104 as described below.

[0069] The distance between the first frame 1001 and the first lens 210 of the first lens assembly 200 can be greater than the distance between the second frame 1101 and the second lens 310 of the second lens assembly 300, that is, the length of the first adapter 1010 is greater than the length of the second adapter 1110, so as to ensure that the ends of the first lens assembly 200 and the second lens assembly 300 can be aligned.

[0070] In optional embodiments, such as Figure 9 As shown, the first transmission component 1400 may include a first rotating component 1410 and a first focusing mount 1420. When the transmission switching component 800 is in the first position, the transmission switching component 800 is transmissionally connected between the focusing operation component 900 and the first rotating component 1410. The first focusing mount 1420 may be threadedly connected to the first focusing frame 1000, and the first rotating component 1410 may be fixedly connected to the first focusing mount 1420. This configuration can reduce the gap or error between the first rotating component 1410 and the first focusing mount 1420, enabling the first focusing mount 1420 to strictly follow the rotation angle and speed of the first rotating component 1410. This, in turn, allows the first focusing frame 1000, which is threadedly connected to the first focusing mount 1420, to achieve precise linear movement, ensuring more accurate focal length adjustment of the first lens assembly 200.

[0071] Of course, the first rotating member 1410 can also be movably connected to the first focusing base 1420.

[0072] like Figure 9 As shown, the second transmission component 1500 includes a second rotating component 1510 and a second focusing mount 1520. When the transmission switching component 800 is in the second position, the transmission switching component 800 is connected to the focusing operation component 900 and the second rotating component 1510. The second focusing mount 1520 is threadedly connected to the second focusing frame 1100, and the second rotating component 1510 is fixedly connected to the second focusing mount 1520. This configuration reduces the gap or error between the second rotating component 1510 and the second focusing mount 1520, allowing the second focusing mount 1520 to strictly follow the rotation angle and speed of the second rotating component 1510. This, in turn, enables the second focusing frame 1100, which is threadedly connected to the second focusing mount 1520, to achieve precise linear movement, ensuring more accurate focal length adjustment of the second lens assembly 300.

[0073] Of course, the second rotating member 1510 can also be movably connected to the second focusing base 1520.

[0074] In some embodiments, such as Figure 9As shown, the first rotating member 1410 and the first focusing seat 1420 can be connected by the first elastic member 1430, allowing the first rotating member 1410 to float axially relative to the first focusing seat 1420. With this configuration, when the sliding drive member 822 and the first rotating member 1410 are connected via gear meshing, when the first drive gear on the sliding drive member 822 and the first rotating gear 1411 on the first rotating member 1410 engage tooth-to-tooth contact, the first rotating gear 1411 on the first rotating member 1410 can float based on the first elastic member 1430, allowing it to retract relative to the first drive gear. This prevents hard wear on the tips of the first drive gear and the first rotating gear 1411, ensuring successful meshing of the first drive gear and the first rotating gear 1411, and extending the service life of the first drive gear and the first rotating gear 1411.

[0075] like Figure 9 As shown, the second rotating member 1510 and the second focusing seat 1520 can be connected by the second elastic member 1530, allowing the second rotating member 1510 to float axially relative to the second focusing seat 1520. With this configuration, when the sliding drive member 822 and the second rotating member 1510 are connected via gear meshing, when the second drive gear on the sliding drive member 822 and the second rotating gear 1511 on the second rotating member 1510 engage tooth-to-tooth contact, the second rotating gear 1511 on the second rotating member 1510 can float based on the second elastic member 1530, allowing it to retract relative to the second drive gear. This prevents hard wear on the tips of the teeth of the second drive gear and the second rotating gear 1511, ensuring successful meshing of the second drive gear and the second rotating gear 1511, and extending the service life of the second drive gear and the second rotating gear 1511.

[0076] Optionally, the first rotating member 1410 and the first focusing seat 1420 can also be engaged, for example, as shown in the example. Figure 9 As shown, one of the first rotating member 1410 and the first focusing base 1420 may be provided with a plurality of first hooks 1412 evenly distributed circumferentially, and the other may be provided with a plurality of first slots. Each first hook 1412 can engage with the corresponding first slot. In this way, the first rotating member 1410 and the first focusing base 1420 are circumferentially limited to prevent relative rotation between the first rotating member 1410 and the first focusing base 1420. Furthermore, while ensuring that the first rotating member 1410 can float relative to the first focusing base 1420, it can also ensure that the first rotating member 1410 can drive the first focusing base 1420 to rotate synchronously.

[0077] The second rotating member 1510 and the second focusing seat 1520 can also be engaged, for example, as shown in the example. Figure 9As shown, one of the second rotating member 1510 and the second focusing base 1520 can be provided with a plurality of second hooks 1512 evenly distributed circumferentially, and the other can be provided with a plurality of second slots. Each second hook 1512 can engage with the corresponding second slot. In this way, the second rotating member 1510 and the second focusing base 1520 can be circumferentially limited to prevent relative rotation between the second rotating member 1510 and the second focusing base 1520. Furthermore, while ensuring that the second rotating member 1510 can float relative to the second focusing base 1520, it can also ensure that the second rotating member 1510 can drive the second focusing base 1520 to rotate synchronously.

[0078] Further optional, such as Figure 9 As shown, the first focusing frame 1000 can be provided with a plurality of first guide posts 1421 evenly distributed circumferentially at one end facing the first rotating member 1410. The first rotating member 1410 can be provided with a plurality of first guide post holes. The first guide posts 1421 can be inserted into the corresponding first guide post holes and move relative to the first guide post holes. This not only guides the floating of the first rotating member 1410 but also ensures that the first rotating member 1410 and the first focusing seat 1420 are circumferentially fixed, allowing the first focusing seat 1420 to rotate synchronously with the first rotating member 1410. Here, the first elastic member 1430 can be sleeved on the outside of the first guide posts 1421.

[0079] like Figure 9 As shown, the second focusing frame 1100 can be provided with a plurality of second guide posts 1521 evenly distributed circumferentially at one end facing the second rotating member 1510. The second rotating member 1510 can be provided with a plurality of second guide post holes. The second guide posts 1521 can be inserted into the corresponding second guide post holes and move relative to them. This not only guides the floating of the second rotating member 1510 but also ensures that the second rotating member 1510 and the second focusing base 1520 are circumferentially fixed, allowing the second focusing base 1520 to rotate synchronously with the second rotating member 1510. Here, the second elastic member 1530 can be sleeved on the second guide posts 1521.

[0080] The number of the first elastic element 1430 mentioned above can be one or more, and this application does not limit this. Here, the number of the first elastic element 1430 is three, and the three first elastic elements 1430 can be evenly distributed along the circumference to ensure that the floating amount of each region of the first rotating element 1410 is the same. The first elastic element 1430 can be a spring.

[0081] The number of the second elastic element 1530 mentioned above can be one or more, and this application does not limit this. Here, the number of the second elastic element 1530 is three, and the three second elastic elements 1530 can be evenly distributed circumferentially to ensure that the floating amount of each region of the second rotating element 1510 is the same. The second elastic element 1530 can be a spring.

[0082] In some embodiments, the binocular observation device may further include a focusing axis assembly 1600, which is parallel to the optical axis direction of the first lens assembly 200 and the second lens assembly 300. A focusing operation member 900 is sleeved on the focusing axis assembly 1600 and fixedly connected to it. A sliding drive member 822 can be sleeved on the focusing axis assembly 1600 and can slide along the axial direction of the focusing axis assembly 1600. The sliding drive member 822 is circumferentially limited to the focusing axis assembly 1600. Rotating the focusing operation member 900 can drive the focusing axis assembly 1600 to rotate, thereby driving the sliding drive member 822 to rotate synchronously. For example, one of the focusing shaft assembly 1600 and the sliding drive member 822 may be provided with a sliding keyway, and the other may be provided with a sliding protrusion 1611. The sliding protrusion 1611 can be embedded in the sliding keyway and engage with the groove wall of the sliding keyway in a circumferential upper limit engagement with the focusing shaft assembly 1600, so that the focusing shaft assembly 1600 and the sliding drive member 822 are circumferentially limited to each other, ensuring that the sliding drive member 822 and the focusing shaft assembly 1600 rotate synchronously. Furthermore, the sliding protrusion 1611 can slide within the sliding keyway, allowing the sliding drive member 822 and the focusing shaft assembly 1600 to slide relative to each other. In this embodiment, the sliding drive member 822 is provided with a sliding keyway, and the focusing shaft assembly 1600 is provided with a sliding protrusion 1611. The sliding connection between the focusing shaft assembly 1600 and the sliding drive member 822 can be achieved without adding a new connecting structure, resulting in a simple structure and convenient assembly.

[0083] Here, since both the focusing operation component 900 and the sliding drive component 822 are mounted on the focusing shaft assembly 1600, the torque transmission between the focusing operation component 900 and the sliding drive component 822 is achieved through the focusing shaft assembly 1600. Compared with the method of transmitting torque through multiple components, this can reduce power loss and improve transmission efficiency.

[0084] When the switching knob 810 is rotated to the first angle, the switching knob 810 drives the sliding drive 822 to move to the first position through the toggle member 821, so that the sliding drive 822 is connected to the first rotating member 1410, thereby realizing the transmission connection between the focusing operation member 900 and the first lens 210 or the first camera movement 220. At this time, by rotating the focusing operation member 900, the sliding drive 822 can be driven to rotate synchronously through the focusing shaft assembly 1600, so that the first rotating member 1410 and the sliding drive 822 rotate synchronously. As the first rotating member 1410 rotates, the first focusing mount 1420 can drive the first focusing frame 1000 to move, thereby driving the first lens 210 or the first camera movement 220 to move, so as to realize the focal length adjustment of the first lens assembly 200. When the switching knob 810 is rotated to the second angle, the switching knob 810 drives the sliding drive 822 to move to the second position through the toggle member 821, so that the sliding drive 822 is connected to the second rotating member 1510 for transmission, so as to realize the transmission connection between the focusing operation member 900 and the second lens 310 or the second camera movement 320. At this time, by rotating the focusing operation member 900, the sliding drive 822 can be driven to rotate synchronously through the focusing shaft assembly 1600, so that the second rotating member 1510 and the sliding drive 822 rotate synchronously. As the second rotating member 1510 rotates, the second focusing mount 1520 can drive the second focusing frame 1100 to move, thereby driving the second lens 310 or the second camera movement 320 to move, so as to realize the focal length adjustment of the second lens assembly 300.

[0085] Optionally, such as Figure 9 As shown, the sliding drive member 822 may include a first drive part 8222 and a second drive part 8223. The first drive part 8222 and the second drive part 8223 may be arranged at intervals along the moving direction of the sliding drive member 822. When the sliding drive member 822 is in the first position, the first drive part 8222 is connected to the first rotating member 1410; when the sliding drive member 822 is in the second position, the second drive part 8223 is connected to the second rotating member 1510.

[0086] For example, the first drive unit 8222 can be snapped, engaged, or magnetically connected to the first rotating member 1410, and the second drive unit 8223 can be snapped, engaged, or magnetically connected to the second rotating member 1510.

[0087] In this embodiment, the first driving unit 8222 may include a first driving gear, and a first rotating gear 1411 may be provided at one end of the first rotating member 1410 facing the first driving unit 8222, and the first rotating gear 1411 meshes with the first driving gear. The second driving unit 8223 may include a second driving gear, and a second rotating gear 1511 may be provided at one end of the second rotating member 1510 facing the second driving unit 8223, and the second rotating gear 1511 meshes with the second driving gear.

[0088] The connection between the first drive unit 8222 and the first rotating member 1410, and the connection between the second drive unit 8223 and the second rotating member 1510, are achieved by meshing a rotating gear and a drive gear. The structure is simple and easy to process. Compared with the method of engaging with protrusions and grooves, the contact area between the first rotating member 1410 or the second rotating member 1510 and the sliding drive unit 822 is increased, resulting in smoother transmission, higher transmission accuracy, and more precise focusing.

[0089] Here, the first rotating gear 1411 can be connected to the first rotating member 1410 by a fastener such as a screw, or the first rotating gear 1411 can be threaded to the first rotating member 1410; the second rotating gear 1511 can be connected to the second rotating member 1510 by a fastener such as a screw, or the second rotating gear 1511 can be threaded to the second rotating member 1510.

[0090] In some embodiments, such as Figure 9 As shown, the sliding drive component 822 may further include a connecting cylinder 8221. The first drive part 8222 and the second drive part 8223 can be sleeved on the connecting cylinder 8221 and connected to it. A clamping space 8224 can be formed between the first drive part 8222 and the second drive part 8223. The clamping space 8224 can be used for partial embedding of the actuating member 821 to facilitate the connection between the actuating member 821 and the sliding drive component 822. Here, the connecting cylinder 8221 can be sleeved on the focusing shaft assembly 1600, and the connecting cylinder 8221 may be provided with the sliding keyway described above.

[0091] For example, the clamping space 8224 can be used for the insertion of the shift fork 8211 described below, and the shape of the shift fork 8211 can be adapted to the shape of the connecting cylinder 8221. In the moving direction of the sliding drive member 822, the shift fork 8211 is limited to the first drive part 8222 and the second drive part 8223, so that the shift fork 8211 can drive the sliding drive member 822 to move.

[0092] In an optional embodiment, the first focusing frame 1000 and the first lens 210 or the first camera module 220 can be rotatably connected via the first adapter 1010. During actual installation, due to factors such as equipment structural design, space limitations, or manufacturing errors, the installation positions of the first lens 210 or the first camera module 220 and the first focusing frame 1000 may not reach an ideal state, resulting in a certain angular deviation between the first lens 210 or the first camera module 220 and the first focusing frame 1000. The first adapter 1010 connects the first lens 210 or the first camera module 220 to the first focusing frame 1000. When the first focusing frame 1000 moves the first lens 210 or the first camera module 220 via the first adapter 1010, the first adapter 1010 can adapt to the position of the first lens 210 or the first camera module 220. This reduces the stress between the first adapter 1010, the first lens 210 or the first camera module 220, and the first focusing frame 1000, thereby preventing deformation of the first lens 210 or the first camera module 220, the first focusing frame 1000, and the first adapter 1010. This helps to extend the service life of the first lens assembly 200, the first focusing frame 1000, and the first adapter 1010.

[0093] Of course, the first focusing frame 1000 can also be fixedly connected to the first lens 210 or the first camera module 220 via the first adapter 1010.

[0094] The second focusing mount 1100 and the second lens 310 or the second camera module 320 can be rotatably connected via the second adapter 1110. During actual installation, due to factors such as equipment structural design, space limitations, or manufacturing errors, the installation positions of the second lens 310 or the second camera module 320 and the second focusing mount 1100 may not reach an ideal state, resulting in a certain angular deviation between the second lens 310 or the second camera module 320 and the second focusing mount 1100. The second adapter 1110 connects the second lens 310 or the second camera module 320 to the second focusing frame 1100. When the second focusing frame 1100 moves the second lens 310 or the second camera module 320 via the second adapter 1110, the second adapter 1110 can adapt to the position of the second lens 310 or the second camera module 320. This reduces the stress between the second adapter 1110 and the second lens 310 or the second camera module 320, and the second focusing frame 1100. Consequently, it prevents the second lens 310 or the second camera module 320, the second focusing frame 1100, and the second adapter 1110 from deforming under stress, thus extending the service life of the second lens assembly 300, the second focusing frame 1100, and the second adapter 1110.

[0095] Of course, the second focusing mount 1100 can also be fixedly connected to the second lens 310 or the second camera module 320 via the second adapter 1110.

[0096] In optional embodiments, such as Figure 4 and Figure 5 As shown, the first end of the first adapter 1010 can be connected to the first focusing frame 1000. Specifically, the first connecting arm 1002 of the first focusing frame 1000 is provided with a first connecting hole 1005, which is connected to the first adapter 1010. The first lens 210 or the first camera module 220 can be provided with one of a first ball head 1011 and a first ball groove 2113, and the second end of the first adapter 1010 can be provided with the other of the first ball head 1011 and the first ball groove 2113. The first ball head 1011 is rotatably disposed in the first ball groove 2113. With this configuration, the first adapter 1010 and the first lens 210 or the first camera module 220 can rotate freely relative to each other in multiple directions through the cooperation of the first ball head 1011 and the first ball groove 2113, so that the first adapter 1010 can adapt to the first lens 210 or the first camera module 220 in different positions.

[0097] Of course, the first ball head 1011 and the first ball groove 2113 may not be provided on the first adapter 1010 and the first lens 210 or the first mechanism 220.

[0098] like Figure 4 and Figure 5 As shown, the first end of the second adapter 1110 can be connected to the second focusing frame 1100. Specifically, the second connecting arm 1102 of the second focusing frame 1100 is provided with a second connecting hole 1105, which is connected to the second adapter 1110. The second lens 310 or the second camera module 320 can be provided with one of a second ball head 1111 and a second ball groove 3113, and the second end of the second adapter 1110 can be provided with the other of the second ball head 1111 and the second ball groove 3113. The second ball head 1111 is rotatably disposed within the second ball groove 3113. With this configuration, the cooperation between the second ball head 1111 and the second ball groove 3113 allows the second adapter 1110 and the second lens 310 or the second camera module 320 to rotate freely relative to each other in multiple directions, so that the second adapter 1110 can adapt to the second lens 310 or the second camera module 320 in different positions.

[0099] Of course, the second ball head 1111 and the second ball groove 3113 may not be provided on the second adapter 1110, the second lens 310 or the second mechanism 320.

[0100] Optionally, the first lens 210 is movably disposed within the housing 100, the first mechanism 220 is fixedly disposed within the housing 100, and the first adapter 1010 can be connected to the first lens 210. The first adapter 1010 can drive the first lens 210 to move, thereby adjusting the distance between the first lens 210 and the first mechanism 220, and thus adjusting the focal length of the first lens assembly 200 to change the position of the focal plane of the image, so that the observed object achieves a clear image in the field of view of the binocular observation device. For example, the first lens 210 can be connected to a first connector 211, and the first connector 211 can be provided with a first ball groove 2113 that connects to the first ball head 1011.

[0101] For example, such as Figure 5 As shown, the first connector 211 may include a first clamping plate 2111 and a second clamping plate 2112. The first clamping plate 2111 can be connected to the first lens 210, and the second clamping plate 2112 can be connected to the first clamping plate 2111. A first ball groove 2113 can be formed between the second clamping plate 2112 and the first clamping plate 2111. Here, the first clamping plate 2111 and the second clamping plate 2112 can clamp the first ball head 1011 to prevent the first ball head 1011 from separating from the first connector 211.

[0102] The second lens 310 is movably disposed within the housing 100, and the second mechanism 320 is fixedly disposed within the housing 100. The second adapter 1110 can be connected to the second lens 310, and the second adapter 1110 can drive the second lens 310 to move, thereby adjusting the distance between the second lens 310 and the second mechanism 320, and thus adjusting the focal length of the second lens assembly 300 to change the position of the focal plane of the image, so that the observed object achieves a clear image in the field of view of the binocular observation device. For example, the second lens 310 can be connected to a second connector 311, and the second connector 311 can be provided with a second ball groove 3113 that connects to the second ball head 1111.

[0103] For example, such as Figure 5 As shown, the second connector 311 may include a third clamping plate 3111 and a fourth clamping plate 3112. The third clamping plate 3111 can be connected to the second lens 310, and the fourth clamping plate 3112 can be connected to the third clamping plate 3111. A second ball groove 3113 can be formed between the fourth clamping plate 3112 and the third clamping plate 3111. Here, the third clamping plate 3111 and the fourth clamping plate 3112 can clamp the second ball head 1111 to prevent the second ball head 1111 from separating from the second connector 311.

[0104] In optional embodiments, such as Figures 3-6As shown, the binocular observation device may further include a housing 100, a first guide rod 1020, and a second guide rod 1120. A focusing operation component 900 may be rotatably connected to the housing 100. The first guide rod 1020 and the second guide rod 1120 may be disposed within the housing 100. The first guide rod 1020 may extend along the moving direction of the first focusing frame 1000, and the second guide rod 1120 may extend along the moving direction of the second focusing frame 1100. Here, the first guide rod 1020 may be located between the first lens assembly 200 and the focusing axis assembly 1600, and the second guide rod 1120 may be located between the second lens assembly 300 and the focusing axis assembly 1600.

[0105] The first focusing frame 1000 may be provided with a first guide hole 1004, and the first guide rod 1020 may be inserted into the first guide hole 1004; the second focusing frame 1100 may be provided with a second guide hole 1104, and the second guide rod 1120 may be inserted into the second guide hole 1104.

[0106] This configuration allows the first guide rod 1020 to guide the movement of the first focusing frame 1000, and the second guide rod 1120 to guide the movement of the second focusing frame 1100. This prevents the first and second focusing frames 1000 from shifting, wobbling, or rotating during movement, thus ensuring the accuracy and stability of focusing on the first lens assembly 200 and the second lens assembly 300. Simultaneously, the first guide rod 1020 and the second guide rod 1120 provide support for the first and second focusing frames 1000 and 1100 respectively, reducing deformation during focusing.

[0107] In other embodiments, the binocular observation device may also exclude the first guide rod 1020 and the second guide rod 1120.

[0108] In optional embodiments, such as Figure 18 As shown, the transmission switching component 820 may include a toggle member 821, which can be connected to a user operating component. The toggle member 821 may have a third guide hole 82131, through which a first guide rod 1020 or a second guide rod 1120 may pass. This configuration allows the first guide rod 1020 or the second guide rod 1120 to guide the toggle member 821, ensuring that the toggle member 821 can only move linearly along the extension direction of the first guide rod 1020 or the second guide rod 1120. This prevents the toggle member 821 from deviating, wobbling, or rotating, thereby ensuring that the toggle member 821 can accurately actuate the sliding drive component 822, enabling the sliding drive component 822 to accurately switch positions.

[0109] In other embodiments, the third guide hole 82131 may not be provided on the toggle member 821.

[0110] In some embodiments of this application, such as Figure 11 As shown, the transmission switching assembly 800 may further include a transmission assembly 830, which includes a base 831, a sliding bracket 832, a guide post 834, and a curved cylinder 833. The base 831 can be fixedly connected to the housing 100 and can be rotatably connected to the focusing shaft assembly 1600. A limiting slot 8311 can be provided on the base 831, the extending direction of which is parallel to the moving direction of the sliding drive member 822. The sliding bracket 832 can be sleeved on the base 831 and can move relative to the base 831. The sliding bracket 832 can be connected to the actuating member 821. The curved cylinder 833 can be fixedly connected to the switching knob 810. A curved groove 8331 can be provided on the cylinder wall of the curved cylinder 833. The curved groove 8331 can be spirally distributed around the axis of the curved cylinder 833. A through hole 8321 can be provided on the sliding bracket 832. The first end of the guide post 834 can be inserted into the curved groove 8331. The second end of the guide post 834 can pass through the through hole 8321 on the sliding bracket 832 and be inserted into the limiting strip hole 8311. The guide post 834 can move relative to the curved groove 8331 and the limiting strip hole 8311 so as to drive the sliding bracket 832 to move, thereby driving the toggle member 821 to move.

[0111] The assembly process of the transmission switching assembly 800 is as follows: the base 831 and the sliding bracket 832 are connected in sequence, the toggle 821 is connected to the sliding bracket 832, the curved cylinder 833 is then fitted over the sliding bracket 832, so that the limiting strip hole 8311, the through hole 8321 and the curved groove 8331 correspond one by one, then the guide post 834 is inserted, and finally the switching knob 810 is fitted over the curved cylinder 833, so that the switching knob 810 and the curved cylinder 833 are fixedly connected.

[0112] Here, the number of guide posts 834 corresponds to the number of through holes 8321, curved grooves 8331, and limiting slots 8311. There can be one or more guide posts to improve the stability of the internal transmission of the transmission switching assembly 800. The number of through holes 8321, limiting slots 8311, and curved grooves 8331 are all three, evenly distributed circumferentially, and correspond one-to-one, so that each guide post 834 can pass through the curved groove 8331, through hole 8321, and limiting slot 8311 in sequence. The base 831 has a through area for the actuating member 821 to pass through the base 831 and connect with the sliding drive member 822.

[0113] In this embodiment, when the user rotates the switching knob 810, the switching knob 810 will drive the curved cylinder 833 to rotate together. Since the curved groove 8331 on the curved cylinder 833 is distributed along the axial thread of the switching knob 810, as the curved cylinder 833 rotates, it will drive the guide post 834 to move along the axial direction of the curved cylinder 833. Since the base 831 is fixed on the housing 100, the limiting strip hole 8311 on the base 831 restricts the rotation of the guide post 834, so that the guide post 834 can only move along the extension direction of the limiting strip hole 8311, which can drive the sliding bracket 832 to move, thereby driving the toggle member 821 to move, so that the toggle member 821 drives the sliding drive member 822 to move, so that the sliding drive member 822 can be connected to the first lens 210 or the first mechanism 220 of the first lens assembly 200, or connected to the second lens 310 or the second mechanism 320 of the second lens assembly 300, realizing the switching of the first lens assembly 200 and the second lens assembly 300.

[0114] Optionally, the curved cylinder 833 and the switching knob 810 can be snapped together. For example, one of the switching knob 810 and the curved cylinder 833 can be provided with a limiting groove, and the other can be provided with a limiting protrusion. The limiting protrusion can be embedded in the limiting groove to achieve the snap-fit ​​between the curved cylinder 833 and the switching knob 810. Of course, the curved cylinder 833 and the switching knob 810 can also be connected by screws or other fasteners.

[0115] In optional embodiments, such as Figure 10 As shown, the actuating element 821 may include a shift fork 8211, a connecting rod 8212, and a limiting rod 8213. The shift fork 8211 can be connected to the sliding drive element 822, one end of the connecting rod 8212 can be connected to the shift fork 8211, and the other end of the connecting rod 8212 can be connected to the sliding bracket 832. The limiting rod 8213 can be connected to the connecting rod 8212. Figure 18 As shown, a third guide hole 82131 can be provided on the limiting rod 8213. The first guide rod 1020 or the second guide rod 1120 can pass through the third guide hole 82131. In this way, through the cooperation between the third guide hole 82131 and the first guide rod 1020 or the second guide rod 1120, the actuating member 821 can only move along the extension direction of the first guide rod 1020 or the second guide rod 1120, so as to avoid the actuating member 821 from shaking, deviating or rotating during the movement.

[0116] Optionally, the sensing element 823 described above can be disposed on the limiting rod 8213, and the first detection element 1310 and the second detection element 1320 can be disposed on the moving path of the limiting rod 8213 so that the first detection element 1310 and the second detection element 1320 can detect the sensing element 823.

[0117] In some embodiments, such as Figure 10 and Figure 18 As shown, the shift fork 8211 can be an arc-shaped structure. The shift fork 8211 can be arranged around the sliding drive member 822 to increase the connection area between the shift fork 8211 and the sliding drive member 822, thereby increasing the force-bearing area of ​​the sliding drive member 822, which is beneficial to extending the service life of the sliding drive member 822 and the shift fork 8211.

[0118] like Figure 10 and Figure 18 As shown, the shift fork 8211 may be provided with an arc-shaped protrusion 8214, and the outer wall of the connecting cylinder 8221 mentioned above may be provided with an arc-shaped groove. The arc-shaped groove is arranged around the axis of the connecting cylinder 8221, and the arc-shaped protrusion 8214 can be embedded in the arc-shaped groove. In this way, the connection stability between the shift fork 8211 and the sliding drive component 822 can be improved.

[0119] Optionally, the switching knob 810 and the focusing control 900 can be arranged adjacent to each other, allowing the user to switch lenses and adjust focus with one hand without having to move the lens. Here, the focusing control 900 can be a focusing knob.

[0120] Here, the adjacent arrangement of the switching knob 810 and the focusing operation component 900 can mean that the switching knob 810 and the focusing operation component 900 are coaxially arranged and attached to each other, and that they can rotate relatively independently without interfering with each other. For example, the switching knob 810 can be located on the side of the focusing operation component 900 closer to the first eyepiece 400 or the second eyepiece 500, or the switching knob 810 can be located on the side of the focusing operation component 900 away from the first eyepiece 400 or the second eyepiece 500.

[0121] The outer contours of the focusing operation component 900 and the switching knob 810 can be the same or different. In this embodiment, the outer wall of the focusing operation component 900 can be evenly spaced with multiple protrusions, and the switching knob 810 can be provided with a toggle protrusion 811 to facilitate toggling the switching knob 810 and to help the user distinguish between the focusing operation component 900 and the switching knob 810.

[0122] Optionally, the focusing operation component 900 may be provided with a receiving cavity, and a portion of the transmission component 830 may be located within the receiving cavity and clearance-fitted with the cavity wall. This arrangement improves space utilization, reduces the axial space occupied by the transmission switching component 800, and makes the structure of the binocular observation device more compact. Furthermore, placing the switching knob 810 closer to the focusing operation component 900 reduces the distance between them.

[0123] In some embodiments, along the direction from the first eyepiece 400 to the first lens assembly 200, the focusing operation member 900, the transmission assembly 830, the first focusing frame 1000, the first transmission member 1400, the sliding drive member 822, the second transmission member 1500, and the second focusing frame 1100 are sequentially distributed. The transmission assembly 830, the first focusing frame 1000, the first transmission member 1400, the second transmission member 1500, and the second focusing frame 1100 are all rotatably connected to the focusing shaft assembly 1600. Since all the above components are mounted on the same focusing shaft assembly 1600, vibration and offset of the components can be avoided when the focusing shaft assembly 1600 rotates, thereby ensuring adjustment accuracy and stability during focusing.

[0124] In this embodiment, as Figure 11 and Figure 13 As shown, the base 831 of the transmission assembly 830 can be rotatably connected to the focusing shaft assembly 1600 via the bearing 1621 to prevent the transmission assembly 830 and the switching knob 810 from rotating with the focusing shaft assembly 1600.

[0125] Optionally, the base 831 can be rotatably connected to the focusing shaft assembly 1600 via two bearings 1621. A bearing bracket 1622 can be provided between the two bearings 1621. The bearing bracket 1622 presses the bearing 1621 closer to the sliding drive member 822 against the first shoulder 1624 protruding on the focusing shaft assembly 1600. The focusing operation member 900 presses the bearing 1621 away from the sliding drive member 822 against the bearing bracket 1622, thus achieving axial positioning of the two bearings 1621. If the diameter of the end face connecting the focusing operation member 900 and the focusing shaft assembly 1600 is smaller than the diameter of the bearing 1621, a bearing pressure ring 1623 can be provided between the focusing operation member 900 and the bearing 1621 to press the bearing 1621 tightly.

[0126] In optional embodiments, such as Figure 13As shown, the focusing shaft assembly 1600 may include a first focusing shaft 1610 and a second focusing shaft 1620. The first focusing shaft 1610 and the second focusing shaft 1620 can be a single, integrally formed structure, meaning they form a single shaft. Alternatively, the first focusing shaft 1610 and the second focusing shaft 1620 can be manufactured separately, forming two independent shafts. When manufactured separately, their ends must be securely connected. For example, the end of the second focusing shaft 1620 is inserted into the first focusing shaft 1610 and connected to it via threaded fasteners. Using an integrally formed structure reduces the number of components in the focusing structure, reducing manufacturing processes and time. When manufactured separately, segmented installation is possible: first, the components on the first focusing shaft 1610 are installed, then the components on the second focusing shaft 1620 are installed, and finally, the two focusing shafts are connected to each other, making installation simpler and more flexible. The components on the first focusing shaft 1610 and the second focusing shaft 1620 can be installed in any order, and can be installed simultaneously to further improve installation efficiency.

[0127] When manufactured separately, although the first focusing shaft 1610 and the second focusing shaft 1620 are fixedly connected by threaded fasteners, they may loosen after long-term use, causing relative rotation between them. To solve this problem, limiting straight surfaces can be provided in the area where the first focusing shaft 1610 and the second focusing shaft 1620 are inserted. The contact of the two limiting straight surfaces prevents relative rotation between the first focusing shaft 1610 and the second focusing shaft 1620, ensuring synchronous rotation of the first focusing shaft 1610 and the second focusing shaft 1620, and guaranteeing the transmission efficiency and adjustment accuracy of the focusing operation component 900 and the sliding drive component 822.

[0128] It should be noted that whether the first focusing shaft 1610 and the second focusing shaft 1620 are integrally formed as one shaft or two independent shafts, their axes must coincide, that is, the focusing shaft assembly 1600 is a coaxial structure. This can prevent the components on the first focusing shaft 1610 and the second focusing shaft 1620 from being relatively offset when the focusing shaft assembly 1600 rotates, thereby ensuring the adjustment accuracy.

[0129] In this embodiment, the first focusing frame 1000, the first transmission component 1400, the sliding drive component 822, the second transmission component 1500, and the second focusing frame 1100 can all be sleeved on the first focusing shaft 1610. The first focusing shaft 1610 can be provided with a sliding protrusion 1611. The base 831 of the transmission switching component 800 and the focusing operation component 900 can be sleeved on the second focusing shaft 1620. The base 831 can be rotatably connected to the second focusing shaft 1620 through a bearing, and the focusing operation component 900 can be fixedly connected to the second focusing shaft 1620.
