Abstract
Description
Technical Field
[0001] This application relates to the field of optical imaging equipment technology, and in particular to a binocular observation device. Background Technology
[0002] In related technologies, binocular observation equipment typically uses a focusing mechanism to synchronously focus two sets of lens assemblies, causing the focusing lenses in the two sets of lens assemblies to move simultaneously along their optical axes. That is, the two focusing lenses always move the same distance.
[0003] If two lens components are of the same type and have the same focusing parameters, synchronous focusing can adjust both focusing lenses to the appropriate position, ensuring both lens components produce a clear image. However, if the two lens components are of different types or have different focusing parameters—for example, one is a visible light lens component and the other is an infrared lens component—synchronous focusing can only adjust the focusing lens of one lens component to the appropriate position, ensuring that one lens component produces a clear image, while the other lens component cannot. If you want the other lens component to produce a clear image, you need to focus on that other lens component separately. In other words, only one lens component can be guaranteed to produce a clear image at a time, resulting in poor image quality and inconvenience. Utility Model Content

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.
[0055] As mentioned in the background section, existing binocular observation equipment typically uses a focusing mechanism to synchronously focus two sets of lens assemblies, causing the focusing lenses in both sets of lens assemblies to move simultaneously along their optical axes. In other words, the two focusing lenses always move the same distance.
[0056] If two lens components are of the same type and have the same focusing parameters, synchronous focusing can adjust both focusing lenses to the appropriate position, ensuring both lens components produce a clear image. However, if the two lens components are of different types or have different focusing parameters—for example, one is a visible light lens component and the other is an infrared lens component—synchronous focusing can only adjust the focusing lens of one lens component to the appropriate position, ensuring that one lens component produces a clear image, while the other lens component cannot. If you want the other lens component to produce a clear image, you need to focus on that other lens component separately. In other words, only one lens component can be guaranteed to produce a clear image at a time, resulting in poor image quality and inconvenience.
[0057] Therefore, this application provides a binocular observation device that has better imaging effect and is more convenient to use.
[0058] See Figures 1 to 4 , Figure 1 One of the perspective views of a binocular observation device provided in the embodiments of this application; Figure 2 for Figure 1 A schematic diagram of the binocular observation device with the button panel hidden. Figure 3 for Figure 1 A schematic diagram of the binocular observation device after its housing has been concealed. Figure 4 for Figure 1 The image shows an exploded view of the binocular observation device near the first and second eyepieces. The binocular observation device according to an embodiment of this application includes:
[0059] A first lens assembly 100 and a second lens assembly 200, wherein the first lens assembly 100 includes a first lens 110, a first mechanism 120 and a first eyepiece 130 arranged sequentially along the incident direction of light, and the second lens assembly 200 includes a second lens 210, a second mechanism 220 and a second eyepiece 230 arranged sequentially along the incident direction of light.
[0060] The focusing operation component 300 is connected to the first lens 110 or the first camera mechanism 120 and can independently drive the first lens 110 or the first camera mechanism 120 to move along the optical axis; and the focusing operation component 300 is connected to the second lens 210 or the second camera mechanism 220 and can independently drive the second lens 210 or the second camera mechanism 220 to move along the optical axis.
[0061] A display 400 is disposed in front of the first eyepiece 130 and / or the second eyepiece 230, and the display 400 is used to display the images captured by the first lens assembly 100 or the second lens assembly 200.
[0062] The switching operation unit 500 is used to switch the display 400 to show the image captured by the first lens assembly 100 or the second lens assembly 200.
[0063] The focusing operation component 300 is disposed between the first lens assembly 100 and the second lens assembly 200, and is located at the end closer to the first eyepiece 130 or the second eyepiece 230.
[0064] The switching operation unit 500 is disposed on the housing 10 of the first lens assembly 100 or the second lens assembly 200 and is located in the gripping area of the housing 10.
[0065] Moving the first lens 110 can mean moving the first lens 110 as a whole, or moving the lens elements within the first lens 110. Moving the second lens 210 can mean moving the second lens 210 as a whole, or moving the lens elements within the second lens 210.
[0066] The binocular observation device provided in this application embodiment has a focusing operation component 300 that can independently move the lenses or mechanisms of each lens assembly along the optical axis. The focusing operation component 300 can adjust the lenses or mechanisms of both the first lens assembly 100 and the second lens assembly 200 to suitable positions with just two adjustments, making it convenient to use. The focusing operation component 300 can adjust both lens assemblies to achieve clear imaging, thereby improving the imaging effect of the binocular observation device.
[0067] The positioning of the focusing control unit 300 and the switching control unit 500 allows for convenient hand operation. When holding the binocular observation device, the user only needs to move one finger to operate the focusing control unit 300 or the switching control unit 500, making operation relatively simple.
[0068] This embodiment of the application allows the switching operation unit 500 to switch the image displayed on the display 400, so that the user can observe the image captured by the target lens assembly, making the binocular observation device more convenient to use. During focusing, the switching operation unit 500 can be used to switch the display 400 to display the image captured by the lens assembly currently being focused. The user can observe the focusing process on the display 400, making it easier to adjust the lens assembly to the desired focal length.
[0069] The lens types of the first lens assembly 100 and the second lens assembly 200 can be the same or different. For example, they can both be visible light lens assemblies, both be infrared light lens assemblies, or one can be a visible light lens assembly and the other can be an infrared light lens assembly.
[0070] like Figure 1 As shown, the first lens 110 and the second lens 210 are the objective lenses of the binocular observation device, located at the end of the housing 10 closer to the object being observed. The first eyepiece 130 and the second eyepiece 230 are located at the end of the housing 10 furthest from the object being observed.
[0071] The aforementioned display 400 is positioned in front of the first eyepiece 130 and / or the second eyepiece 230, meaning that the display 400 is located on the side of the first eyepiece 130 closer to the first lens 110 and / or on the side of the second eyepiece 230 closer to the second lens 210.
[0072] The number of displays 400 can be one or two. When there is one display 400, the display 400 is positioned in front of one of the eyepieces, and the image displayed on the display 400 is transmitted to the front of the other eyepiece through optical elements.
[0073] like Figure 4 As shown, the display 400 may include a first display 410 and a second display 420. The first display 410 is located in front of the first eyepiece 130, and the second display 420 is located in front of the second eyepiece 230. Both the first display 410 and the second display 420 display images captured by the first lens assembly 100, or both display images captured by the second lens assembly 200.
[0074] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the binocular observation device includes: circuit board 600;
[0075] The circuit board 600 is electrically connected to the first mechanism 120, the second mechanism 220, the display 400, and the switching operation unit 500;
[0076] The first mechanism 120 can send the image signal captured by the first lens 110 to the circuit board 600; the second mechanism 220 can send the image signal captured by the second lens 210 to the circuit board 600.
[0077] The circuit board 600 can switch the image signal sent to the display 400 after receiving the image switching signal triggered by the switching operation unit 500.
[0078] Both the first movement 120 and the second movement 220 include an image sensor. The light captured by the lens can be transmitted to the image sensor of the corresponding movement. The image sensor converts the received light signal into an electrical signal and transmits the electrical signal to the circuit board 600.
[0079] For example, after the circuit board 600 acquires the image signals captured by the first lens 110 and the second lens 210, it sends the image signal captured by the first lens 110 to the display 400, and the display 400 displays the image captured by the first lens 110. When the user operates the switching operation unit 500 to switch images, the circuit board 600 sends the image signal captured by the second lens 210 to the display 400, and the display 400 displays the image captured by the second lens 210.
[0080] The image displayed on the display 400 before the user operates the switching device 500 corresponds to the image displayed by the binocular observation device before it was powered off during the last use. Therefore, before the user operates the switching device 500, the display 400 can display either the image captured by the first lens 110 or the image captured by the second lens 210; this application does not limit the display to either.
[0081] By applying the embodiments of this application, signal transmission is achieved through electrical connection between the circuit board 600 and the above-mentioned components, which simplifies the electrical connection relationship and makes control more convenient.
[0082] Switching operation unit 500 can be like Figure 1 The image shown is displayed using a button. By pressing the image switching button 510, the image displayed on the display 400 is switched. In other embodiments of this application, the switching operation element 500 may also take the form of a lever or other means, and the image displayed on the display 400 is switched by moving the lever or other means.
[0083] like Figure 1 and Figure 2 As shown, when the switching operation unit 500 is in the form of a button, the switching operation unit 500 includes: an image switching button 510 and a button circuit board 520. The image switching button 510 is electrically connected to the button circuit board 520, and the button circuit board 520 is electrically connected to the circuit board 600. Pressing the image switching button 510 triggers the button circuit board 520 to send an image switching signal to the circuit board 600.
[0084] In some embodiments of this application, see Figure 5 , Figure 5 for Figure 1 A perspective view of the shell shown. Figure 2 and Figure 5 As shown, the binocular observation device includes a housing 10, and the holding area is the middle area of the housing 10 between the first lens 110 and the first eyepiece 130 and the middle area of the housing 10 between the second lens 210 and the second eyepiece 230; or, the holding area is the area of the housing 10 near the first eyepiece 130 and the area near the second eyepiece 230.
[0085] In this embodiment, the grip area is distributed symmetrically on the housing 10 of the first lens assembly 100 and the second lens assembly 200, making the device more stable for the user when holding it. The focusing control 300 is located in or near the grip area, and the switching control 500 is located in the grip area, allowing the user to move a finger to focus or switch images while holding the device, making operation more convenient.
[0086] like Figure 5 As shown, the housing 10 has a receiving cavity 11 inside. Wherein, as... Figure 2 As shown, the housing 10 may include a front housing 101, a middle housing 102, and a rear housing 103 arranged sequentially along the light incident direction. The first lens 110 and the first movement 120 of the first lens assembly 100, and the second lens 210 and the second movement 220 of the second lens assembly 200 are arranged side-by-side and spaced apart in the receiving cavity 11 of the front housing 101. The middle housing 102 is the gripping area, and the focusing operation member 300 is disposed in the middle housing 102, partially located in the receiving cavity 11 of the middle housing 102 and partially located outside the middle housing 102. The button circuit board 520 and the circuit board 600 of the switching operation member 500 are both disposed in the receiving cavity 11 of the middle housing 102, with the button circuit board 520 located at the top of the focusing operation member 300 and the circuit board 600 located at the bottom of the focusing operation member 300. The first eyepiece 130 and the second eyepiece 230 are located outside the receiving cavity 11 and are arranged side-by-side and spaced apart on the side of the rear housing 103 away from the front housing 101. The display 400, located in front of the first eyepiece 130 and / or the second eyepiece 230, can be electrically connected to the circuit board 600 in the receiving cavity 11 via a cable passing through a through hole on the rear housing 103.
[0087] like Figure 1 and Figure 2 As shown, the housing 10 includes a cover plate 12, which is located in the middle housing 102 region and covers the top of the receiving cavity 11. An image switching button 510 is disposed on the cover plate 12 and passes through the cover plate 12 to be electrically connected to the button circuit board 520. With this arrangement, the circuit board 600 is positioned close to the first mechanism 120, the second mechanism 220, the display 400, and the switching operation component 500, avoiding complex internal wiring and simplifying the internal structural layout of the binocular observation device.
[0088] The cover plate 12 may also be provided with at least one function button 121, such as a power button, menu button, menu page turning button, shooting button, etc. The function button 121 is electrically connected to the circuit board 600 so as to control the circuit board 600 as needed.
[0089] See Figure 6 , Figure 6This is a second perspective view of a binocular observation device provided in an embodiment of this application. The binocular observation device further includes: a supplementary lighting module 800 and a laser ranging module 900. The supplementary lighting module 800 and the laser ranging module 900 are fixed to the housing 10, located between the first lens assembly 100 and the second lens assembly 200, and located at the end of the focusing operation component 300 near the first lens assembly 100 and the second lens assembly 200. The supplementary lighting module 800 is used to provide auxiliary illumination in low light conditions to improve the imaging effect of the binocular observation device; the laser ranging module 900 is used to measure the distance between the binocular observation device and the observed object.
[0090] The middle shell 102 may be provided with a cable interface for electrical connection to external devices. A waterproof cover 14 may be provided at the cable interface to seal it. The middle shell 102 may also be provided with a bracket interface 15 to facilitate the mounting of the binocular observation equipment on a bracket, such as a tripod.
[0091] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the focusing operation component 300 includes:
[0092] The first transmission mechanism 310a is connected to the first lens 110 or the first mechanism 120.
[0093] The second transmission mechanism 310b is connected to the second lens 210 or the second mechanism 220.
[0094] The operating component is switchably connected to the first transmission mechanism 310a and the second transmission mechanism 310b. The operating component drives the first lens 110 or the first mechanism 120 to move along the optical axis direction through the first transmission mechanism 310a, and drives the second lens 210 or the second mechanism 220 to move along the optical axis direction through the second transmission mechanism 310b.
[0095] In the embodiments of this application, the two transmission mechanisms share a set of operating components, and the operating components can independently drive the two transmission mechanisms, making the structure of the focusing operating component 300 simple and easy to control. By pulling the lens or the camera movement through the transmission mechanism, the distance between the imaging surface of the lens and the camera movement is adjusted, thereby achieving focus adjustment and enabling the binocular observation device to present clear images in different scenarios.
[0096] Specifically, in Figure 3In the illustrated embodiment, the first transmission mechanism 310a is connected to the first lens 110, and the second transmission structure 310b is connected to the second lens 210. Both the first lens 110 and the second lens 210 include lens modules. The transmission mechanism can move the entire lens module, or it can move one or more lenses within the lens module; this application does not limit this. In other embodiments of this application, the first transmission mechanism 310a can be connected to the first movement 120, and the second transmission structure 310b can be connected to the second movement 220; or one transmission mechanism can be connected to the lens, and the other transmission mechanism can be connected to the movement; this application does not limit this.
[0097] The above-mentioned operating components can be as follows: Figure 3 The operation shown adopts an operation mode of one focusing knob 330 and one switching knob 340. By switching the switching knob 340, the focusing knob 330 is connected to the lens or movement in different lens assemblies to realize independent focusing of the first lens assembly 100 and the second lens assembly 200. The operation component can also adopt an operation mode of two focusing knobs, with the two focusing knobs respectively adjusting the focal length of a set of lens assemblies to realize independent focusing of the two lens assemblies.
[0098] The following section will first describe the binocular observation device when the operating components adopt the first operating mode.
[0099] In some embodiments of this application, see Figure 7 , Figure 7 for Figure 1 A cross-sectional view of the binocular observation device shown. Figure 3 and Figure 7 As shown, the operation components include:
[0100] The first focusing axis 320 is located between the first lens assembly 100 and the second lens assembly 200, and is arranged in a direction parallel to the optical axis;
[0101] The focusing knob 330 is fixedly sleeved on the first focusing shaft 320 and can rotate around the axial direction of the first focusing shaft 320.
[0102] The switching knob 340 is rotated and sleeved on the first focusing shaft 320, and can rotate around the axis of the first focusing shaft 320.
[0103] Drive mechanism 350, drive mechanism 350 and switching knob 340 are connected by transmission;
[0104] Rotate the switching knob 340 to the first position, which drives the drive mechanism 350 to be connected between the focusing knob 330 and the first transmission mechanism 310a, so that the focusing knob 330 drives the first lens 110 or the first mechanism 120 to move along the optical axis direction through the drive mechanism 350 and the first transmission mechanism 310a.
[0105] Rotate the switching knob 340 to the second position, which drives the drive mechanism 350 to be connected between the focusing knob 330 and the second transmission structure 310b, so that the focusing knob 330 drives the second lens 210 or the second mechanism 220 to move along the optical axis through the drive mechanism 350 and the second transmission mechanism 310b.
[0106] Using the embodiments of this application, focusing can be completed simply by rotating the switching knob 340 and the focusing knob 330, making the focusing process relatively simple. When the first lens assembly 100 and the second lens assembly 200 are of different types or have different focusing parameters, the lenses or mechanisms of the first lens assembly 100 and the second lens assembly 200 can be adjusted to appropriate positions through the above-described individual adjustment process, so that both lens assemblies can form clear images, thereby improving the imaging effect of the binocular observation device.
[0107] Specifically, the first position and the second position are different positions of the switching knob 340 when it rotates around the axial direction. For example, turning the switching knob 340 to the left to the first position will enable the drive mechanism 350 to drive the focusing knob 330 to the first transmission mechanism 310a, and turning the switching knob 340 to the right to the second position will enable the drive mechanism 350 to drive the focusing knob 330 to the second transmission structure 310b.
[0108] The focus knob 330 and the switching knob 340 can be used as follows: Figure 3 As shown, the focus knob 330 and the switching knob 340 are arranged adjacently on the first focusing axis 320, or they can be arranged at intervals; this application does not limit this arrangement. When arranged adjacently, the adjacent end faces of the focus knob 330 and the switching knob 340 are fitted together, and the focus knob 330 and the switching knob 340 can rotate relatively independently around the axis of the first focusing axis 320 without interfering with each other. The switching knob 340 can be located on the side of the focus knob 330 away from the first lens 110 and the second lens 210, or it can be arranged as shown... Figure 3 The focus knob 330 is located on the side near the first lens 110 and the second lens 210, as shown. This application will subsequently describe the application using the example of the switch knob 340 being located on the side of the focus knob 330 near the first lens 110 and the second lens 210.
[0109] The outer contours of the focus knob 330 and the switching knob 340 may be the same or different. Figure 3In the embodiment shown, the focusing knob 330 has multiple protrusions evenly spaced, while the switching knob 340 has only one toggle protrusion 3431, so that the user can easily distinguish between the two knobs and also easily toggle the switching knob 340 to different positions.
[0110] In some embodiments of this application, see Figure 8 , Figure 8 for Figure 7 One of the enlarged views of the binocular observation device shown. (See attached image.) Figure 7 and Figure 8 As shown, the drive mechanism 350 includes: a sliding drive member 351;
[0111] The sliding drive component 351 is slidably sleeved on the first focusing shaft 320 along the axial direction, and is connected to the focusing knob 330 through the first focusing shaft 320.
[0112] The first transmission mechanism 310a and the second transmission mechanism 310b are sleeved on the first focusing shaft 320 and are located on both sides of the sliding drive member 351, respectively.
[0113] When the switching knob 340 is rotated to the first position, the sliding drive 351 moves axially to be connected to the first transmission mechanism 310a, thus connecting the focusing knob 330 and the first transmission mechanism 310a.
[0114] When the switching knob 340 is rotated to the second position, the sliding drive 351 moves axially to be connected to the second transmission mechanism 310b, thereby connecting the focusing knob 330 and the second transmission mechanism 310b.
[0115] In the embodiments of this application, the focusing knob 330, the switching knob 340, the drive mechanism 350, the first transmission mechanism 310a, and the second transmission mechanism 310b are all mounted on the first focusing shaft 320, making the focusing operation component 300 easy to install and structurally stable. Due to the structural stability, the aforementioned components can rotate stably around or move axially along the first focusing shaft 320, thereby ensuring high focusing accuracy. Furthermore, torque transmission between the focusing knob 330 and the sliding drive component 351 is achieved through the first focusing shaft 320, allowing torque transmission without direct contact between the two components, making the arrangement of the sliding drive component 351 more flexible. Moreover, torque transmission through the first focusing shaft 320, compared to transmitting torque through multiple components, reduces power loss and improves the transmission efficiency between the focusing knob 330 and the sliding drive component 351.
[0116] exist Figure 7In the illustrated embodiment, the portion of the first transmission mechanism 310a sleeved on the first focusing shaft 320 is located on the side of the sliding drive member 351 closer to the switching knob 340, and the portion of the second transmission mechanism 310b sleeved on the first focusing shaft 320 is located on the side of the sliding drive member 351 away from the switching knob 340. In other embodiments of this application, the positions of the first transmission mechanism 310a and the second transmission mechanism 310b may be interchanged, and this application does not limit this.
[0117] The specific implementation of the aforementioned sliding drive component 351 being axially slidably sleeved on the first focusing shaft 320 is as follows: Figure 8 As shown, the first focusing shaft 320 is provided with a sliding keyway 321 extending axially, and the sliding drive member 351 is provided with a protrusion that cooperates with the sliding keyway 321, so that the sliding drive member 351 can slide along the axial direction of the first focusing shaft 320; the sliding drive member 351 is limited by the sliding keyway 321 in the circumferential direction of the first focusing shaft 320, and can rotate synchronously with the first focusing shaft 320, but cannot rotate relative to the first focusing shaft 320.
[0118] By applying the above structure, a sliding keyway 321 is provided on the first focusing shaft 320, and a protrusion is provided on the sliding drive component 351. This allows for a sliding connection between the first focusing shaft 320 and the sliding drive component 351 without the need for additional connecting structures, resulting in a simple, compact structure and easy assembly of the adjustment mechanism 100. The cooperation between the sliding keyway 321 and the protrusion ensures synchronous rotation between the sliding drive component 351 and the first focusing shaft 320, thereby guaranteeing high focusing accuracy.
[0119] like Figure 7 As shown, the first focusing shaft 320 includes a first shaft segment 320a and a second shaft segment 320b. The first shaft segment 320a and the second shaft segment 320b can be an integrally formed structure, meaning they are one shaft; alternatively, the first shaft segment 320a and the second shaft segment 320b can be manufactured separately, forming two independent shafts. When they are manufactured separately, their ends must be securely connected, for example, Figure 7 The end of the second shaft segment 320b shown is inserted into the first shaft segment 320a and connected to each other by threaded fasteners. Using a one-piece molded structure reduces the number of parts, manufacturing processes, and time. When manufactured separately, segmented installation is possible: first, the parts on the first shaft segment 320a are installed, then the parts on the second shaft segment 320b are installed, and finally the two shaft segments are connected, making installation simpler and more flexible. The installation of the parts on the first shaft segment 320a and the second shaft segment 320b does not have a specific order and can be performed simultaneously to further improve installation efficiency.
[0120] See Figure 9 , Figure 9 for Figure 7 A three-dimensional view of the second axis segment is shown. Figure 7 and Figure 9 As shown, in the area where the first shaft segment 320a and the second shaft segment 320b are inserted, both the first shaft segment 320a and the second shaft segment 320b have a limiting plane 322 (in Figure 9 Only the limiting plane 322 on the second shaft segment 320b is shown. The fit of the two limiting planes 322 prevents relative rotation between the first shaft segment 320a and the second shaft segment 320b, reduces the risk of loosening of the connection between the two shaft segments after long-term use, and ensures the synchronous rotation of the first shaft segment 320a and the second shaft segment 320b. This ensures the transmission efficiency from the focusing knob 330 to the sliding drive 351 and the focusing accuracy of the focusing knob 330.
[0121] Whether the first shaft segment 320a and the second shaft segment 320b are integrally formed as one shaft or two independent shafts, their axes must coincide, that is, the first focusing shaft 320 is a coaxial structure. This can prevent the components on the first shaft segment 320a and the second shaft segment 320b from being relatively offset when the first focusing shaft 320 rotates, thereby ensuring focusing accuracy.
[0122] The specific positional relationships of the components mounted on the first focusing shaft 320 are as follows: Figure 7 As shown, the focusing knob 330 and the switching knob 340 are mounted abutting each other on the first shaft segment 320a, and the first transmission mechanism 310a, the drive mechanism 350, and the second transmission mechanism 310b are spaced apart on the second shaft segment 320b. The focusing knob 330 is fixed to the end of the first shaft segment 320a furthest from the first lens 110 and the second lens 210, and is fixedly connected to the first shaft segment 320a by threaded fasteners. One axial end face of the switching knob 340 is abutting the focusing knob 330, and the other axial end face is spaced apart from the input end of the first transmission mechanism 310a to allow space for the housing 10 to rotate with the first focusing shaft 320. This positional arrangement of the components makes the focusing operation component 300 axially compact.
[0123] like Figure 9 As shown, at least one weight-reducing hole 328 is provided on the second shaft section 320b. When there are multiple weight-reducing holes 328, they can be arranged at intervals along the axial direction. Without affecting the transmission and structural strength of the second shaft section 320b, the weight of the first focusing shaft 320 is reduced, making the binocular observation equipment lighter.
[0124] In some embodiments of this application, see Figure 10 , Figure 10 for Figure 7 The second enlarged view of the binocular observation device shown. Figure 7 and Figure 10As shown, the switching knob 340 includes: an actuator 341 and a first curved cylinder 342;
[0125] The actuator 341 is sleeved on the first focusing shaft 320 and can move along the axial direction of the first focusing shaft 320; the first curved cylinder 342 is sleeved outside the actuator 341 and can rotate around the axial direction of the first focusing shaft 320.
[0126] The first curved cylinder 342 has a first curved groove 3421 on its cylinder wall. The first end of the actuator 341 is slidably connected to the first curved groove 3421, and the second end is connected to the sliding drive 351.
[0127] When the first curved cylinder 342 rotates, it can convert its own rotation into the axial movement of the actuator 341 through the first curved slide groove 3421, so that the actuator 341 drives the sliding drive 351 to move axially.
[0128] In this embodiment of the application, rotation is converted into axial movement through the transmission of the actuator 341 and the first curved cylinder 342, which simplifies the structure of the switching knob 340 and facilitates its processing and assembly. The nested arrangement of the actuator 341 and the first curved cylinder 342 shortens the axial length of the switching knob 340, making the focusing operation component 300 more compact in the axial direction.
[0129] In some embodiments of this application, such as Figure 7 As shown, the drive mechanism 350 includes a sliding drive member 351 and a lever 352. The sliding drive member 351 is connected to the actuator 341 via the lever 352. The first end of the lever 352 is connected to the actuator 341, and the second end passes through the transmission mechanism between the switching knob 340 and the sliding drive member 351, and is connected to the sliding drive member 351.
[0130] When the first curved cylinder 342 rotates and drives the actuator 341 to move axially, the actuator 341 drives the sliding drive 351 to move axially via the lever 352, so that the sliding drive 351 is connected to one of the transmission mechanisms.
[0131] By applying the embodiments of this application, the actuator 341 and the sliding drive 351 are connected by the lever 352 across the transmission mechanism, thereby realizing the transmission between the actuator 341 and the sliding drive 351. This simplifies the structure of the focusing mechanism 10 and makes the arrangement of the relative positions of the switching knob 340 and the sliding drive 351 more flexible.
[0132] This application does not limit the structure of the lever 352. Any structure that can connect one end to the actuator 341 and the other end to the sliding drive 351 can be used as the lever 352.
[0133] See Figure 11 , Figure 11 for Figure 7 A 3D view of the lever shown. (As shown) Figure 8 and Figure 11 As shown, the lever 352 includes a fork link 3521 and a fork 3522 fixedly connected together. The first end of the fork link 3521 is fixedly connected to the actuator 341, and the second end extends across the first transmission mechanism 310a to the radial side of the sliding drive member 351. A fork engagement groove 3511 is provided on the outer periphery of the sliding drive member 351. The opening of the fork engagement groove 3511 faces outwards to allow the fork 3522 to be inserted. The fork 3522 is fixed to the second end of the fork link 3521, and a protrusion on the fork 3522 engages with the fork engagement groove 3511 on the sliding drive member 351 to achieve a fixed connection between the lever 352 and the sliding drive member 351. The specific position of the fork engagement groove 3511 on the sliding drive member 351 is not limited in this application; the length of the lever 352 can be determined based on the position of the fork engagement groove 3511.
[0134] When the fork mating groove 3511 of the sliding drive component 351 is circular or arc-shaped, such as Figure 11 As shown, the outline of the shift fork 3522 can be set to arc shape, and the protrusion on it for engaging with the shift fork mating groove 3511 is also arc shape. By applying the above structure, the contact area between the shift fork 3522 and the sliding drive member 351 can be increased, thereby improving the stability of the shift lever 352 driving the sliding drive member 351 to move.
[0135] In some embodiments of this application, such as Figure 10 As shown, a knob housing 343 is fixedly fitted onto the outside of the first curved cylinder 342. Rotating the knob housing 343 can drive the first curved cylinder 342 to rotate. The knob housing 343 is in contact with the focusing knob 330.
[0136] The focusing knob 330 has an opening on the side facing the switching knob 340. The actuator 341 and the first curved cylinder 342 extend through the opening into a receiving cavity inside the focusing knob 330.
[0137] Using the embodiments of this application, the actuator 341 can move within the internal space enclosed by the knob housing 343, the focusing knob 330, the first focusing shaft 320, and the housing 10, so that the switching knob 340 is flat on the side end face near the first lens 110 and the second lens 210. Overall, while ensuring that the actuator 341 has sufficient axial movement space, the space utilization rate is improved, the axial space occupied by the switching knob 340 is shortened, and the axial length of the first focusing shaft 320 can be set to be shorter, making the structure of the focusing operation member 300 more compact.
[0138] Specifically, the fixed connection between the first curved cylinder 342 and the knob housing 343 can be a snap-fit connection, the specific implementation of which can be found in [reference needed]. Figure 12 , Figure 12 for Figure 3 The exploded view of the switching knob is shown. Figure 12 As shown, at least one limiting groove 3432 is provided on the end face of the knob housing 343, and the opening of the limiting groove 3432 faces the inside of the knob housing 343. The first curved cylinder 342 is provided with the same number of limiting protrusions 3422 on the corresponding end face. The limiting protrusions 3422 are inserted into the limiting grooves 3432 in the axial direction, so that the first curved cylinder 342 and the knob housing 343 are engaged, thereby realizing the synchronous rotation of the first curved cylinder 342 and the knob housing 343.
[0139] In some embodiments of this application, such as Figure 6 and Figure 10 As shown, the housing 10 has a fixing plate 13, which can be located in the middle housing 102 region. The fixing plate 13 is rotatably sleeved on the first focusing shaft 320, ensuring that the rotation of the first focusing shaft 320 is not restricted by the housing 10. The fixing plate 13 is in contact with the end face of the knob housing 343 away from the focusing knob 330, sealing off this end face, so that the actuator 341 can move within the internal space enclosed by the knob housing 343, the focusing knob 330, the first focusing shaft 320, and the fixing plate 13.
[0140] In this embodiment of the application, the end face of the knob housing 343 away from the focusing knob 330 is sealed by the fixing plate 13, making the binocular observation device compact in structure and simple in appearance. The first focusing shaft 320 extends through the first through hole 131 on the fixing plate 13 to install the transmission mechanism and the drive mechanism 350. The lever 352 passes through the second through hole 132 on the fixing plate 13, connecting the actuator 341 and the sliding drive 351 located on both sides of the fixing plate 13.
[0141] The first curved cylinder 342 rotates axially around the first focusing shaft 320, and its rotation axis passes through the center of the first through hole 131. Since there is a gap between the first through hole 131 and the second through hole 132, the fixing plate 13 can restrict the lever 352 and the actuator 341 to follow the first curved cylinder 342 to rotate axially around the first focusing shaft 320 through the second through hole 132, thereby causing the actuator 341 and the lever 352 to move axially.
[0142] See Figure 13 , Figure 13 for Figure 12 The figure shows a perspective view of the knob housing. The circumferential side wall of the knob housing 343 is provided with an outwardly protruding toggle protrusion 3431 for the user to toggle and switch positions.
[0143] One of the fixing plate 13 of the housing 10 and the knob housing 343 may be provided with at least one groove, and the other may be provided with a corresponding number of limiting parts. This application will describe the example where the knob housing 343 is provided with a groove 3433 and the fixing plate 13 of the housing 10 is provided with limiting parts 133.
[0144] In some embodiments of this application, such as Figure 13 As shown, two grooves 3433 are provided on the end face of the knob housing 343 near the fixing plate 13. The two grooves 3433 can be distributed circumferentially along the knob housing 343. When the switching knob 340 is rotated to the first position, at least a portion of the limiting part 133 is embedded in one groove 3433. When the switching knob 340 is rotated to the second position, at least a portion of the limiting part 133 is embedded in the other groove 3433.
[0145] This design allows for a noticeable click and change in resistance when the limiting part 133 is engaged in one of the grooves 3433, providing clear tactile feedback to the user and allowing them to perceive whether the switch has been successful. Furthermore, when at least a portion of the limiting part 133 is engaged in the groove 3433, the limiting engagement between the limiting part 133 and the groove 3433 locks the switching knob 340 in its current position to a certain extent. This prevents the switching knob 340 from rotating due to slight impacts or vibrations, making it less prone to accidental triggering and ensuring the binocular observation device remains in the desired mode.
[0146] The specific structure of the limiting part 133 can be as follows: Figure 10 As shown, the device includes an elastic element 1331 and a ball bearing 1332 connected to the elastic element 1331. When the switching knob 340 is rotated to the first position, the elastic element 1331 drives the ball bearing 1332 to engage in one groove 3433. When the switching knob 340 is rotated to the second position, the elastic element 1331 drives the ball bearing 1332 to engage in another groove 3433. This configuration, due to the elasticity of the elastic element 1331, allows the ball bearing 1332 to disengage from the groove 3433 without requiring excessive force when rotating the switching knob 340, thus facilitating the rotation of the switching knob 340. Furthermore, after the ball bearing 1332 is embedded in the groove 3433, the restraint of the groove 3433 on the ball bearing 1332 and the elastic force of the elastic element 1331 effectively lock the switching knob 340 in the current position. Unless the user applies sufficient force to overcome the elastic force of the elastic element 1331 and the friction between the ball bearing 1332 and the groove 3433, the switching knob 340 will not turn easily, thus ensuring the stability of the binocular observation device.
[0147] In other embodiments of this application, the limiting part 133 may only include the ball 1332, or the limiting part 133 may be a spherical protrusion.
[0148] In some embodiments of this application, see Figure 14 , Figure 14 for Figure 10 A perspective view of the first base shown. Figure 10 and Figure 14 As shown, a first base 344 is sleeved between the actuator 341 and the first focusing shaft 320.
[0149] The first base 344 is rotatably connected to the first focusing shaft 320. The end of the first base 344 is fixedly connected to the fixing plate 13 of the housing 10. A first limiting waist hole 3441 parallel to the first focusing shaft 320 is provided on the outer wall of the first base 344. The third end of the actuator 341 is slidably connected to the first limiting waist hole 3441.
[0150] Since the first base 344 is fixedly connected to the fixing plate 13 of the housing 10, when the knob housing 343 is rotated, the first base 344 remains stationary. The first limiting waist hole 3441 on the first base 344 restricts the rotation of the actuator 341 so that the actuator 341 can move along the axial direction of the first focusing shaft 320 when the first curved cylinder 342 rotates.
[0151] By applying the embodiments of this application, a first base 344 is provided, and a first limiting waist hole 3441 is opened on the first base 344 to limit and guide the actuator 341, restricting the rotation of the actuator 341, thereby converting the rotation of the first curved cylinder 342 into the axial movement of the actuator 341. The method of slotting the first base 344 and the first curved cylinder 342 to cooperate with the actuator 341 makes the switching knob 340 simple in structure and easy to manufacture. The first base 344, actuator 341, first curved cylinder 342, and knob housing 343 are nested layer by layer, making the switching knob 340 compact in structure and easy to assemble. This reduces the axial space occupied by the switching knob 340, allowing the axial length of the first focusing shaft 320 to be set shorter, resulting in a more compact structure of the focusing mechanism 10.
[0152] like Figure 10 and Figure 14 As shown, the end of the first base 344 that is connected to the fixing plate 13 protrudes outward in the radial direction to form a base connecting plate 3442. The base connecting plate 3442 is fitted to the fixing plate 13, so that the first base 344 and the fixing plate 13 have a large contact area, preventing the actuator 341 from rotating due to loosening of the first base 344, thereby ensuring high focusing accuracy.
[0153] The base connecting plate 3442 is used to cooperate with the fixed plate 13 to clamp the first curved cylinder 342 and the knob housing 343, preventing the first curved cylinder 342 from moving axially. The base connecting plate 3442 is provided with a through area so that the lever 352 can pass through the first base 344 and be fixedly connected to the actuator 341.
[0154] The specific implementation method of the rotatable connection between the first base 344 and the first focusing shaft 320 is as follows: Figure 10 As shown, a bearing 345 is sleeved between the first base 344 and the first focusing shaft 320. The inner ring of the bearing 345 is tightly fitted with the first focusing shaft 320, and the outer ring is tightly fitted with the first base 344 to achieve a rotatable connection and prevent the rotation of the first focusing shaft 320 from being restricted by the switching knob 340 when the focusing knob 330 is rotated.
[0155] The quantity of bearing 345 is not limited in this application. Figure 10 In the illustrated embodiment, there are two bearings 345, and a bearing bracket 346 is provided between the two bearings 345. The bearing bracket 346 presses the bearing 345 located near the sliding drive member 351 against the first shoulder 323 protruding on the first focusing shaft 320; the end face of the connection between the focusing knob 330 and the first focusing shaft 320 presses the bearing 345 located away from the sliding drive member 351 against the bearing bracket 346, thus achieving axial positioning of the two bearings 345. Figure 10 As shown, if the diameter of the end face of the connection between the focusing knob 330 and the first focusing shaft 320 is smaller than the diameter of the bearing 345, a bearing pressure ring 347 can be fitted on the connection end to press the entire bearing 345 tightly.
[0156] In some embodiments of this application, such as Figure 10 and Figure 12 As shown, the actuator 341 includes: a first movable bracket 3411 and a first guide post 3412.
[0157] The first movable bracket 3411 is sleeved between the first base 344 and the first curved cylinder 342, and is connected to the sliding drive component 351 of the drive mechanism 350. The first movable bracket 3411 is provided with a first mounting through hole 3413.
[0158] The first guide post 3412 is disposed in the first mounting through hole 3413. The first end of the first guide post 3412 is movably inserted into the first curved slide groove 3421, and the second end is movably inserted into the first limiting waist hole 3441.
[0159] When the first curved cylinder 342 rotates, the first end of the first guide post 3412 moves along the first curved slide groove 3421, and the second end moves along the first limiting waist hole 3441, so as to drive the first movable bracket 3411 and the sliding drive member 351 to move axially.
[0160] In the embodiments of this application, the actuator 341 includes a first movable bracket 3411 and a first guide post 3412. During installation, the first movable bracket 3411 can be first sleeved with the first base 344 and the first curved cylinder 342, and then the first guide post 3412 can be inserted, making the actuator 341 simple in structure and easy to process and assemble.
[0161] The specific assembly process of the switching knob 340 is as follows: The first base 344 is fitted inside the first curved cylinder 342, and the first movable bracket 3411 is fitted between the first base 344 and the first curved cylinder 342, so that the first limiting waist hole 3441, the first mounting through hole 3413 and the first curved slide groove 3421 correspond. Then, the first guide post 3412 is inserted, and the knob housing 343 is fitted outside the first curved cylinder 342, so that the knob housing 343 and the first curved cylinder 342 are engaged. Finally, the assembled whole is fitted onto the first focusing shaft 320, and the first base 344 is fixedly connected to the fixing plate 13. The lever 352 is inserted into the through area of the first base 344, and the first movable bracket 3411 and the lever 352 are threaded together from the other side.
[0162] Specifically, the number of first guide posts 3412 corresponds to the number of first mounting through holes 3413, first curved slide grooves 3421 and first limiting waist holes 3441. There can be one or more of them to improve the stability of the internal transmission of the switching knob 340. Figure 12 In the embodiment shown, the number of the first mounting through hole 3413, the first limiting waist hole 3441, and the first curved groove 3421 are all 3, and they are evenly distributed along the circumference and correspond one-to-one, so that each first guide post 3412 can pass through the first curved groove 3421, the first mounting through hole 3413, and the first limiting waist hole 3441 in sequence.
[0163] like Figure 12 As shown, the area on the first movable bracket 3411 without the first mounting through hole 3413 has a thickness in the axial direction that is less than the thickness of the area with the first mounting through hole 3413, so as to reduce the weight of the first movable bracket 3411 and thus reduce the overall weight of the focusing operation component 300.
[0164] In some embodiments of this application, such as Figure 7 and Figure 8 As shown, both the first transmission mechanism 310a and the second transmission mechanism 310b include: a rotating member 311 and an adjusting member 312;
[0165] Rotating component 311 is rotatably sleeved on the first focusing shaft 320 for transmission connection with sliding drive component 351; adjusting component 312 is sleeved on rotating component 311 and threadedly connected to rotating component 311; adjusting component 312 of the first transmission mechanism 310a is fixedly connected to the first lens 110 or the first mechanism 120; adjusting component 312 of the second transmission mechanism 310b is fixedly connected to the second lens 210 or the second mechanism 220.
[0166] The rotating component 311 can convert its own rotation into the axial movement of the adjusting component 312 through a threaded connection;
[0167] When the sliding drive 351 is connected to the rotating part 311 of the first transmission mechanism 310a, the focusing knob 330 is rotated, which drives the first focusing shaft 320, the sliding drive 351 and the rotating part 311 to rotate, so that the adjusting part 312 of the first transmission mechanism 310a drives the first lens 110 or the first mechanism 120 to move axially.
[0168] When the sliding drive 351 is connected to the rotating part 311 of the second transmission mechanism 310b, rotating the focusing knob 330 drives the first focusing shaft 320, the sliding drive 351 and the rotating part 311 to rotate, causing the adjusting part 312 of the second transmission mechanism 310b to drive the second lens 210 or the second movement 220 to move axially.
[0169] The distance between the rotating parts 311 of the first transmission mechanism 310a and the second transmission mechanism 310b is greater than the axial dimension of the sliding drive part 351, so that when the sliding drive part 351 is connected to one rotating part 311, it is completely disengaged from the other rotating part 311, preventing the sliding drive part 351 from driving the two rotating parts 311 to rotate at the same time.
[0170] In the embodiments of this application, the adjusting member 312 is fixedly connected to the lens or movement, enabling the adjusting member 312 to move the lens or movement while also restricting the adjusting member 312 from rotating with the rotating member 311. This eliminates the need for an additional limiting mechanism to restrict the rotation of the adjusting member 312, simplifying the transmission mechanism's structure. Furthermore, the rotating member 311 and the adjusting member 312 are connected by a thread, and the rotation of the adjusting member 312 is restricted in the aforementioned manner, converting the rotation of the rotating member 311 into axial movement of the adjusting member 312. This simplifies the transmission mechanism's structure and facilitates its manufacturing.
[0171] In some embodiments of this application, the rotating member 311 and the sliding drive member 351 are driven by meshing. Alternatively, one of the rotating member 311 and the sliding drive member 351 has a protrusion and the other has a groove; the rotating member 311 and the sliding drive member 351 are driven by engaging with the protrusion and the groove. By applying the embodiments of this application, the rotating member 311 and the sliding drive member 351 are connected by meshing or engaging, so that the sliding drive member 351 can drive the rotating member 311 to rotate, and the structure of the rotating member 311 and the sliding drive member 351 is simple and easy to manufacture.
[0172] The following describes an embodiment in which the rotating member 311 and the sliding drive member 351 are engaged.
[0173] In some embodiments of this application, see Figure 15 , Figure 15 for Figure 3 The exploded view shows the first and second transmission mechanisms. The sliding drive component 351 is a drive gear. The rotating component 311 includes a rotating gear 3111.
[0174] The drive gear has teeth on both sides along the axial direction, which are used to mesh with the rotating gear 3111 of the first transmission mechanism 310a or the second transmission mechanism 310b, so as to drive the rotating gear 3111 meshing with it to rotate.
[0175] In the embodiments of this application, the rotating gear 3111 and the driving gear are meshed and connected, which is simple in structure and easy to process. Compared with the snap-fit connection through protrusions and grooves, the contact area between the rotating part 311 and the sliding driving part 351 is increased, which makes the transmission smoother, the transmission accuracy higher, and enables more precise focusing.
[0176] Specifically, the rotating gear 3111 can be directly threaded to the adjusting member 312, that is, the part of the rotating gear 3111 that fits into the adjusting member 312 is provided with external or internal threads, and is threadedly connected to the adjusting member 312. The rotating gear 3111 can also be indirectly threaded to the adjusting member 312 through other components, as detailed in the following description.
[0177] In some embodiments of this application, such as Figure 8 and Figure 15 As shown, the rotating component 311 also includes a threaded bracket 3112 and a spring 3113.
[0178] The rotating gear 3111, spring 3113 and threaded bracket 3112 are arranged sequentially in a direction away from the sliding drive 351.
[0179] The threaded bracket 3112 is rotatably sleeved on the first focusing shaft 320, and the axial position of the threaded bracket 3112 is fixed. The threaded bracket 3112 is engaged with the rotating gear 3111, so that the threaded bracket 3112 can rotate with the rotating gear 3111. The adjusting element 312 is threadedly sleeved on the threaded bracket 3112.
[0180] Spring 3113 abuts against rotating gear 3111 and threaded bracket 3112, allowing rotating gear 3111 to float axially relative to threaded bracket 3112.
[0181] In the embodiments of this application, when the drive gear moves toward the rotating gear 3111, if the drive gear and the rotating gear 3111 have a tooth-to-tooth contact, the rotating gear 3111 can float based on the spring 3113 and move backward relative to the drive gear to prevent damage to the tooth tips and ensure successful meshing between the drive gear and the rotating gear 3111.
[0182] Specifically, in this embodiment, the rotating gear 3111 is indirectly connected to the adjusting member 312 via a threaded bracket 3112. The threaded bracket 3112 has an external thread, and the adjusting member 312 has an internal thread. The adjusting member 312 is sleeved on the outside of the threaded bracket 3112 and threadedly connected to it. The axial thickness of the adjusting member 312 is not limited in this application; the adjusting member 312 can be made relatively thin, exposing part of the rotating member 311, or it can be... Figure 8 As shown, the entire rotating component 311 is enclosed to protect the rotating gear 3111 and the spring 3113 from damage by impact; and the axial space occupied by the transmission mechanism on the first focusing shaft 320 is shortened, making the transmission mechanism structure more compact and the first focusing shaft 320 can be set shorter.
[0183] Both threaded brackets 3112 of the two rotating parts 311 can be rotatably connected to the first focusing shaft 320 via bearings, and axial positioning can be achieved by providing a protruding shoulder on the first focusing shaft 320. Specifically, as follows... Figure 8 and Figure 9 As shown, the diameter of the first shaft segment 320a of the first focusing shaft 320 is larger than that of the second shaft segment 320b, resulting in a second shoulder at the end face of the first shaft segment 320a. The second shaft segment 320b has a raised third shoulder 324, and the threaded bracket 3112 of the first transmission mechanism 310a is fixed in the gap between the second shoulder and the third shoulder 324 to achieve axial position fixation.
[0184] The second shaft segment 320b has a raised fourth shaft shoulder 325 and a threaded connection part 326 at one end near the first lens 110 and the second lens 210. A nut 327 is threaded on the threaded connection part 326. The nut 327 presses the threaded bracket 3112 of the second transmission mechanism 310b against the fourth shaft shoulder 325 to fix the axial position.
[0185] One specific implementation of the engagement between the aforementioned threaded bracket 3112 and the rotating gear 3111 is as follows: Figure 8 and Figure 15 As shown, the rotating gear 3111 is provided with a plurality of hooks 3114 evenly distributed along the circumference, and the threaded bracket 3112 is provided with a plurality of hook holes 3115 correspondingly. The hooks 3114 pass through the hook holes 3115 to achieve engagement, which can restrict the rotation of the threaded bracket 3112 relative to the rotating gear 3111, and can also restrict the rotating gear 3111 from moving away from the threaded bracket 3112 to cause disengagement.
[0186] The threaded bracket 3112 is provided with a plurality of guide posts 3116 evenly distributed along the circumference on the side facing the rotating gear 3111. The rotating gear 3111 is provided with a plurality of guide post holes (not shown in the figure). The guide posts 3116 are inserted into the guide post holes to guide the floating of the rotating gear 3111 and ensure that the threaded bracket 3112 and the rotating gear 3111 rotate synchronously.
[0187] The number of springs 3113 can be one or more; this application does not limit this. Figure 15 In the embodiment shown, there are 3 springs 3113, which are evenly distributed circumferentially to ensure that the floating amount of each region of the rotating gear 3111 is the same.
[0188] In some embodiments of this application, such as Figure 3 and Figure 8 As shown, the adjusting component 312 includes: a focusing bracket 3121 and a connecting rod 3122.
[0189] The focusing bracket 3121 is threaded onto the rotating part 311. One end of the connecting rod 3122 is fixedly connected to the focusing bracket 3121, and the other end is fixedly connected to the lens or movement of the corresponding lens assembly.
[0190] When the rotating component 311 rotates, the focusing bracket 3121 can drive the connecting rod 3122 to move axially, thereby driving the corresponding lens or movement to move axially.
[0191] In the embodiments of this application, the adjusting member 312 includes a focusing bracket 3121 and a connecting rod 3122. The position of the connecting rod 3122 can be flexibly set according to the internal structural layout of the housing 10. The focusing brackets 3121 of the two transmission mechanisms can be configured as follows: Figure 3 As shown, the two connecting rods 3122 extend to different sides of the first focusing shaft 320 and connect to the connecting rod 3122, so that the two connecting rods 3122 are respectively located on both sides of the first focusing shaft 320, avoiding interference between the connecting rods 3122 and other structures during focusing, and also making the weight distribution of the binocular observation device uniform.
[0192] like Figure 8 As shown, the focusing bracket 3121 is provided with a first limiting member 3126 and a second limiting member 3127. The first limiting member 3126 is located on the side of the threaded bracket 3112 near the sliding drive member 351, and can be limited and engaged with the end face of the threaded bracket 3112 near the sliding drive member 351; the second limiting member 3127 is located on the side of the threaded bracket 3112 away from the sliding drive member 351, and can be limited and engaged with the end face of the threaded bracket 3112 away from the sliding drive member 351.
[0193] The axial distance between the first limiting member 3126 and the second limiting member 3127 is the movable distance of the focusing bracket 3121, which is also the movable distance of the lens or movement connected to the focusing bracket 3121.
[0194] By applying the embodiments of this application, the axial movement range of the focusing bracket 3121 is limited by setting the first limiting member 3126 and the second limiting member 3127, and the structure is relatively simple.
[0195] exist Figure 8 In the illustrated embodiment, the first limiting member 3126 is a protrusion on the inner wall of the focusing bracket 3121. When the focusing bracket 3121 moves to its extreme position away from the sliding drive member 351, the protrusion abuts against the end face of the threaded bracket 3112 near the sliding drive member 351. Specifically, the protrusion can be a screw. After the focusing bracket 3121 is fitted onto the threaded bracket 3112, the screw is screwed in from the outer wall, so that it protrudes from the inner wall of the focusing bracket 3121.
[0196] The second limiting member 3127 is the end face of the focusing bracket 3121. When the focusing bracket 3121 moves to the limit position close to the sliding drive member 351, the end face of the focusing bracket 3121 abuts against the end face of the threaded bracket 3112 away from the sliding drive member 351.
[0197] In other embodiments of this application, the structural forms of the first limiting member 3126 and the second limiting member 3127 may be interchanged or the same structural form may be used. This application does not limit the scope of the invention.
[0198] In some embodiments of this application, such as Figure 3 As shown, the focusing operation component 300 also includes a first limiting guide rod 391.
[0199] The first limiting guide rod 391 is disposed in the receiving cavity 11 of the housing 10, arranged in a direction parallel to the optical axis, and fixedly connected to the housing 10, specifically it can be connected to the fixing plate 13. The focusing bracket 3121 is slidably sleeved on the first limiting guide rod 391.
[0200] In this embodiment, a first limiting guide rod 391 fixedly connected to the housing 10 is provided. This limits the rotation of the adjusting member 312 and guides its axial movement, ensuring that the adjusting member 312 always moves axially and guaranteeing focusing accuracy. Compared to the method where the focusing bracket 3121 is connected to the corresponding lens or camera movement via only one connecting rod 3122 to achieve rotation limiting, this embodiment avoids the connecting rod 3122 from wobbling due to the end of the connecting rod 3122 connected to the focusing bracket 3121 having a tendency to rotate while the end connected to the lens or camera movement remains stationary. This reduces the risk of the connecting rod 3122 wobbling affecting focusing accuracy and extends its lifespan.
[0201] The number of first limiting guide rods 391 is not limited in this application; there can be one, located on one side of the first focusing shaft 320, with both focusing brackets 3121 slidably connected to the first limiting guide rod 391; or... Figure 3 As shown, there are two first limiting guide rods 391 respectively located on both sides of the first focusing shaft 320, and each of the two focusing brackets 3121 is slidably connected to one of the first limiting guide rods 391.
[0202] Using one first limiting guide rod 391 can reduce the number of parts and make the structure of the focusing mechanism 10 more compact; using two first limiting guide rods 391 means that the two focusing brackets 3121 do not need to share one first limiting guide rod 391, making the layout more flexible.
[0203] like Figure 3 and Figure 11 As shown, the lever 352 can also be slidably connected to the first limiting guide rod 391. The lever connecting rod 3521 is provided with a lever through hole 3523 for the first limiting guide rod 391 to pass through, which improves the stability of the axial movement of the lever 352.
[0204] Since the distance between the focusing bracket 3121 of the first transmission mechanism 310a and the first lens 110 is greater than the distance between the focusing bracket 3121 of the second transmission mechanism 310b and the second lens 210, the lengths of the two connecting rods 3122 are different to ensure that the first lens 110 and the second lens 210 are aligned.
[0205] The structural shape of the connecting rod 3122 can be set according to the positions of the first lens 110, the second lens 210, and the focusing bracket 3121. The connecting rod 3122 can be a one-piece molded rod or assembled from at least two rods. This application does not limit the structural shape of the connecting rod 3122.
[0206] In some embodiments of this application, see Figure 16 and Figure 17 , Figure 16 for Figure 1 One of the exploded views of the binocular observation equipment shown; Figure 17 for Figure 1 The second exploded view of the binocular observation device shown. Figure 16 and Figure 17 As shown, each connecting rod 3122 includes: a ball-head connecting rod 3123, a fixing rod 3124, and a ball-head pressure plate 3125.
[0207] The first end of the ball joint connecting rod 3123 is fixedly connected to the focusing bracket 3121, and the first end of the fixing rod 3124 is fixedly connected to the camera mechanism or lens. The ball joint at the second end of the ball joint connecting rod 3123 is rotatably disposed in the ball groove at the second end of the fixing rod 3124. Through the cooperation between the ball joint and the ball groove, the ball joint connecting rod 3123 can rotate freely relative to the fixing rod 3124 when the transmission mechanism is installed, which can realize the adjustment of the posture of the connecting rod 3122 to adapt to the first lens 110 and the second lens 210 in different positions.
[0208] After adjusting the posture, the ball head of the ball head connecting rod 3123 is pressed into the ball groove of the fixing rod 3124 by the ball head pressure plate 3125, so as to fix the relative position of the ball head connecting rod 3123 and the fixing rod 3124, and avoid relative rotation between the ball head connecting rod 3123 and the fixing rod 3124 during focusing, which would affect the focusing accuracy.
[0209] The following describes the binocular observation device when the operating components adopt the second operating mode.
[0210] See Figures 18 to 20 , Figure 18 One of the perspective views of another binocular observation device provided in the embodiments of this application; Figure 19 A second perspective view of another binocular observation device provided in the embodiments of this application; Figure 20 for Figure 18The diagram shows the binocular observation device after the cover plate has been hidden. Except for the specific structure of the focusing operation component 300, the specific structures and positional connections of the other components of the binocular observation device in this embodiment are the same as those of the binocular observation device when the aforementioned operation components adopt the first operation mode, and will not be described again here.
[0211] See Figure 21 , Figure 21 for Figure 18 The diagram shows the binocular observation device after its housing has been concealed. Figure 20 and Figure 21 As shown, the focusing operation component 300 includes:
[0212] The first transmission mechanism 310a is connected to the first lens 110 or the first mechanism 120.
[0213] The second transmission mechanism 310b is connected to the second lens 210 or the second mechanism 220.
[0214] The operating components include: a first focusing knob 370, which is connected to a first transmission mechanism 310a; and a second focusing knob 380, which is connected to a second transmission mechanism 310b.
[0215] Rotating the first focusing knob 370 causes the first lens 110 or the first camera module 120 to move along the optical axis via the first transmission mechanism 310a; rotating the second focusing knob 380 causes the second lens 210 or the second camera module 220 to move along the optical axis via the second transmission mechanism 310b.
[0216] By applying the embodiments of this application, the first lens assembly 100 can be clearly imaged by rotating the first focusing knob 370, and the second lens assembly 200 can be clearly imaged by rotating the second focusing knob 380. This not only simplifies the focusing method, but also ensures that both the first lens assembly 100 and the second lens assembly 200 are clearly imaged, thereby improving the imaging effect of the binocular observation device.
[0217] In some embodiments of this application, such as Figure 20 and Figure 21 As shown, the operating components include: a second focusing axis 360; the second focusing axis 360 is located between the first lens assembly 100 and the second lens assembly 200, and is arranged in a direction parallel to the optical axis;
[0218] The first focusing knob 370 is fixedly sleeved on the second focusing shaft 360 and can rotate around the axial direction of the second focusing shaft 360; the second focusing knob 380 is rotatably sleeved on the second focusing shaft 360 and can rotate around the axial direction of the second focusing shaft 360.
[0219] In the embodiments of this application, the first focusing knob 370 and the second focusing knob 380 are both sleeved on the second focusing shaft 360, making the structure of the operating component simple and compact. The first focusing knob 370 is fixedly sleeved on the second focusing shaft 360, and the second focusing knob 380 is rotatably sleeved on the second focusing shaft 360, so that when the first focusing knob 370 is rotated, the rotation of the second focusing shaft 360 is not restricted by the second focusing knob 380, thereby realizing independent focusing of the first lens assembly 100 and the second lens assembly 200.
[0220] The first focus knob 370 and the second focus knob 380 can be used as follows: Figure 21 As shown, the first focusing knob 370 and the second focusing knob 380 are arranged adjacent to each other on the second focusing axis 360, or they can be arranged at intervals; this application does not limit this arrangement. When arranged adjacently, the adjacent end faces of the first focusing knob 370 and the second focusing knob 380 are fitted together, making the focusing operation component 300 compact in the axial direction, enabling focusing with one hand without moving the position, which is convenient for the user to focus; and the first focusing knob 370 and the second focusing knob 380 can rotate relatively independently around the axial direction of the second focusing axis 360 without interfering with each other. This application does not limit the relative positional relationship between the first focusing knob 370 and the second focusing knob 380. The second focusing knob 380 can be located on the side of the first focusing knob 370 away from the first lens 110 and the second lens 210, or it can be arranged as follows: Figure 21 The first focusing knob 370 is located on the side near the first lens 110 and the second lens 210, as shown. This application will subsequently describe the application using the example of the second focusing knob 380 being located on the side of the first focusing knob 370 near the first lens 110 and the second lens 210.
[0221] The outer contours of the first focusing knob 370 and the second focusing knob 380 can be the same or different. Figure 21 In the illustrated embodiment, the outer surface of the first focusing knob 370 has a plurality of first protrusions spaced circumferentially. The outer surface of the second focusing knob 380 has a plurality of second protrusions. The different numbers and shapes of the two types of protrusions facilitate user differentiation and memorization of the lens components corresponding to the two focusing knobs, thereby enabling faster and more accurate rotation of the focusing knob corresponding to the lens component to be focused. In addition, the first and second protrusions also serve as anti-slip features. In other embodiments of this application, the outer contour forms of the first focusing knob 370 and the second focusing knob 380 can be interchanged, or an outer contour form can be used.
[0222] In some embodiments of this application, see Figure 22 and Figure 23 , Figure 22 for Figure 18 One of the exploded views of the binocular observation equipment shown; Figure 23 for Figure 18 The second exploded view of the binocular observation device shown. Figures 21 to 23 As shown, the first transmission mechanism 310a includes: a first focusing bracket 313 and a first connecting rod 314;
[0223] The first focusing bracket 313 is sleeved on the second focusing shaft 360 and is connected to the first focusing knob 370 via the second focusing shaft 360.
[0224] The first focusing bracket 313 and the second focusing shaft 360 are provided, one of which is provided with a curved groove extending along the axial direction, and the other is provided with a protrusion movably installed in the curved groove; or, the first focusing bracket 313 and the second focusing shaft 360 are threadedly connected; the first focusing bracket 313 converts the rotation of the second focusing shaft 360 into its own axial movement by means of the cooperation of the curved groove and the protrusion, or by means of the threaded connection.
[0225] One end of the first connecting rod 314 is fixedly connected to the first focusing bracket 313, and the other end is fixedly connected to the first lens 110 or the first mechanism 120.
[0226] When the first focusing knob 370 is rotated, the second focusing shaft 360 rotates and drives the first focusing bracket 313 to move axially, which in turn drives the first lens 110 or the first movement 120 to move axially via the first connecting rod 314.
[0227] Using the embodiments of this application, the first connecting rod 314 can realize the transmission between the first focusing bracket 313 and the first lens 110 or the first mechanism 120 of the first lens assembly 100; and the first lens assembly 100 can restrict the rotation of the first connecting rod 314, thereby restricting the first focusing bracket 313 to rotate with the second focusing shaft 360, without the need to set an additional limiting mechanism to restrict the rotation of the first focusing bracket 313, making the structure of the first transmission mechanism 310a relatively simple.
[0228] In this embodiment, the first focusing bracket 313 converts the rotation of the second focusing shaft 360 into its own axial movement through one of the two connection methods described above. This results in fewer parts and a simpler structure for the first transmission mechanism 310a, making it easier to process and assemble. Using a threaded connection simplifies the installation of the first focusing bracket 313 and makes the connection more stable. It prevents relative wobbling during transmission between the second focusing shaft 360 and the first focusing bracket 313, improving the stability of the first transmission mechanism 310a and thus ensuring focusing accuracy and stability during focusing.
[0229] In this embodiment, torque transmission between the first focusing knob 370 and the first focusing bracket 313 is achieved through the second focusing shaft 360. Compared with transmitting torque through multiple components, this reduces power loss and improves the transmission efficiency between the first focusing knob 370 and the first focusing bracket 313. Furthermore, torque transmission between the first focusing knob 370 and the first focusing bracket 313 does not require direct contact, making the arrangement of the first focusing bracket 313 more flexible.
[0230] The specific location of the first focusing bracket 313 is not limited in this application; it can be located outside the first focusing knob 370 and the second focusing knob 380, for example... Figure 20 and Figure 21 As shown, the second focusing shaft 360 passes through the fixing plate 13 of the housing 10 and extends toward the first lens 110 and the second lens 210. The first focusing bracket 313 is sleeved on the part of the second focusing shaft 360 that extends out of the fixing plate 13, located on the side of the fixing plate 13 away from the first focusing knob 370; alternatively, it can be located in the internal space enclosed by the second focusing shaft 360, the first focusing knob 370, the second focusing knob 380, and the fixing plate 13, sharing the axial length space of the second focusing shaft 360 with the first focusing knob 370 and the second focusing knob 380, and connected to the first lens 110 or the first mechanism 120 through the fixing plate 13 via the first connecting rod 314. This application will subsequently describe the case where the first focusing bracket 313 is located outside the first focusing knob 370 and the second focusing knob 380.
[0231] In some embodiments of this application, see Figure 24 and Figure 25 , Figure 24 for Figure 18 One of the cross-sectional views of the binocular observation device shown; Figure 25 for Figure 18 The second cross-sectional view of the binocular observation device shown.
[0232] The first focusing knob 370 is fixed to the end of the second focusing shaft 360 away from the first lens 110 and the second lens 210. The second focusing knob 380 is in contact with the end face of the first focusing knob 370. The first focusing bracket 313 is disposed at the end of the second focusing shaft 360 near the first lens 110 and the second lens 210. There is a gap between the first focusing bracket 313 and the second focusing knob 380 to allow for the installation space of the fixing plate 13 and the axial movement space of the first focusing bracket 313. With the above arrangement, the focusing operation components 300 are arranged more compactly in axial length, and the axial length of the second focusing shaft 360 can be set to be shorter.
[0233] In some embodiments of this application, see Figure 26 , Figure 26 for Figure 25A partially enlarged view of the binocular observation device shown. The second focusing axis 360 has protruding fifth shoulder 361 and sixth shoulder 362. Both fifth shoulder 361 and sixth shoulder 362 are located on the side of the fixing plate 13 furthest from the first focusing knob 370. Fifth shoulder 361 is located between the fixing plate 13 and sixth shoulder 362.
[0234] The first focusing bracket 313 has a third limiting member 3131 and a fourth limiting member 3132. The third limiting member 3131 is located on the side of the fifth shoulder 361 near the fixing plate 13 and can be limited and engaged with the end face of the fifth shoulder 361; the fourth limiting member 3132 is located on the side of the sixth shoulder 362 away from the fixing plate 13 and can be limited and engaged with the end face of the sixth shoulder 362.
[0235] The axial distance between the third limiting member 3131 and the fourth limiting member 3132 is the movable distance of the first focusing bracket 313 on the second focusing axis 360, which is also the movable distance of the first lens 110 or the first mechanism 120 of the first lens assembly 100.
[0236] By applying the embodiments of this application, the axial movement range of the first focusing bracket 313 is limited by setting the third limiting member 3131 and the fourth limiting member 3132, and the structure is relatively simple.
[0237] exist Figure 26 In the embodiment shown, the third limiting member 3131 is the end face of the first focusing bracket 313. When the first focusing bracket 313 moves to the extreme position away from the first focusing knob 370, the end face of the first focusing bracket 313 abuts against the end face of the fifth shoulder 361.
[0238] The fourth limiting member 3132 is a protrusion on the inner wall of the first focusing bracket 313. When the first focusing bracket 313 moves to its extreme position near the first focusing knob 370, this protrusion abuts against the end face of the sixth shoulder 362. The sixth shoulder 362 may be the end face of the second focusing shaft 360. Specifically, this protrusion may be a screw. After the first focusing bracket 313 is fitted onto the second focusing shaft 360, the screw is screwed in from the outer wall, so that it protrudes from the inner wall of the first focusing bracket 313.
[0239] In other embodiments of this application, the structural forms of the third limiting member 3131 and the fourth limiting member 3132 may be interchanged or the same structural form may be used. This application does not limit this.
[0240] In some embodiments of this application, such as Figures 24 to 26 As shown, the second transmission mechanism 310b includes: a movable part 315 and a second curved cylinder 316;
[0241] The movable part 315 is sleeved on the second focusing shaft 360 and can move along the axial direction of the second focusing shaft 360; the second curved cylinder 316 is sleeved between the movable part 315 and the second focusing knob 380, and is fixedly connected to the second focusing knob 380, and can rotate around the axial direction of the second focusing shaft 360.
[0242] The second curved cylinder 316 has a second curved groove 3161 on its cylinder wall. The first end of the movable part 315 is slidably connected to the second curved groove 3161, and the second end is connected to the second lens 210 or the second mechanism 220.
[0243] When the second curved cylinder 316 rotates, it can convert its own rotation into the axial movement of the movable part 315 through the second curved slide groove 3161, so that the movable part 315 drives the second lens 210 or the second mechanism 220 to move axially.
[0244] In the embodiments of this application, rotation is converted into axial movement through the transmission of the movable member 315 and the second curved cylinder 316, making the structure of the second transmission mechanism 310b simple and easy to process and assemble. The nested arrangement of the movable member 315 and the second curved cylinder 316 can shorten the length occupied by the second transmission mechanism 310b on the second focusing shaft 360, making the structure more compact.
[0245] The first focusing knob 370, the second focusing knob 380, the first transmission mechanism 310a, and the second transmission mechanism 310b are all mounted on the second focusing shaft 360 and are coaxially arranged. This simplifies the installation and maintenance of the focusing operation component 300 and prevents vibration and displacement of the above components when the second focusing shaft 360 rotates. This makes the structure of the focusing operation component 300 stable, and ensures that the above components rotate or move stably around the second focusing shaft 360 axially, thereby guaranteeing focusing accuracy and stability during focusing.
[0246] The first end of the movable part 315 of the second transmission mechanism 310b is located inside the second focusing knob 380, and the second end passes through the fixing plate 13 and is connected to the second lens 210 or the second mechanism 220. That is, the first end of the movable part 315 and the second focusing knob 380 share the axial length space of the second focusing shaft 360, which can improve the space utilization rate and does not need to occupy the area of the second focusing shaft 360 that extends out of the second focusing knob 380, so that the axial length of the second focusing shaft 360 can be set shorter, and the structure of the focusing operation part 300 is more compact.
[0247] The first focusing knob 370 has an opening on the side facing the second focusing knob 380. The movable member 315 and the second curved cylinder 316 pass through the opening and extend into the receiving cavity inside the first focusing knob 370, leaving space for the axial movement of the movable member 315 and improving space utilization.
[0248] The fixed connection between the second curved cylinder 316 and the second focusing knob 380 can be a snap-fit connection, the specific implementation of which can be described in the following ways: Figure 12 The first curved cylinder 342 shown is connected to the knob housing 343 in the same way, which will not be described again here.
[0249] In some embodiments of this application, such as Figure 26 As shown, a second base 317 is fitted between the movable part 315 and the second focusing shaft 360. The second base 317 is rotatably connected to the second focusing shaft 360. The end of the second base 317 is fixedly connected to the fixing plate 13 of the housing 10.
[0250] The outer wall of the second base 317 is provided with a second limiting waist hole 3171 parallel to the second focusing shaft 360. The third end of the movable member 315 is slidably connected to the second limiting waist hole 3171 so that the movable member 315 can move axially along the second focusing shaft 360 when the second curved cylinder 316 rotates.
[0251] By applying the embodiments of this application, a second base 317 is provided, and a second limiting hole 3171 is opened on the second base 317 to restrict the rotation of the movable part 315, thereby converting the rotation of the second curved cylinder 316 into the axial movement of the movable part 315. The method of slotting the second base 317 and the second curved cylinder 316 to cooperate with the movable part 315 simplifies the structure of the second transmission mechanism 310b, making it easy to process and disassemble. The second base 317, the movable part 315, the second curved cylinder 316, and the second focusing knob 380 are nested layer by layer, making the second transmission mechanism 310b and the second focusing knob 380 compactly assembled. The axial length of the second focusing shaft 360 can be set shorter, resulting in a more compact structure for the focusing operation component 300.
[0252] The specific structure of the second base 317 mentioned above can be compared with... Figure 14 The first base 344 shown is the same; the specific implementation of the rotatable connection between the second base 317 and the second focusing shaft 360 can be the same as... Figure 10 The first base 344 shown is connected to the first focusing shaft 320 in the same way, which will not be described again here.
[0253] In some embodiments of this application, such as Figure 23 and Figure 26 As shown, the movable component 315 includes: a second movable bracket 3151 and a second guide post 3152.
[0254] The second movable bracket 3151 is sleeved between the second base 317 and the second curved cylinder 316, and is connected to the second lens 210 or the second mechanism 220 via a connector passing through the second base 317 and the fixing plate 13. The second movable bracket 3151 is provided with a second mounting through hole 3153. The second guide post 3152 is disposed in the second mounting through hole 3153, with its first end movably inserted into the second curved slide groove 3161 and its second end movably inserted into the second limiting waist hole 3171.
[0255] When the second curved cylinder 316 rotates, the first end of the second guide post 3152 moves along the second curved slide groove 3161, and the second end moves along the second limiting waist hole 3171, so as to drive the second movable bracket 3151 and the connector, as well as the second lens 210 or the second mechanism 220 to move axially.
[0256] By applying the embodiments of this application, when assembling the second transmission mechanism 310b, the second movable bracket 3151 can be first sleeved with the second base 317 and the second curved cylinder 316, and then the second guide post 3152 can be inserted, so that the movable part 315 has a simple structure and is easy to process and assemble.
[0257] Specifically, the specific structures of the second curved cylinder 316, the second movable support 3151, and the second guide post 3152 can be the same as those of the second curved cylinder 316, the second movable support 3151, and the second guide post 3152. Figure 12 The first curved cylinder 342, the first movable bracket 3411 and the first guide post 3412 shown are the same, and will not be described again here.
[0258] In some embodiments of this application, such as Figures 21 to 23 As shown, the connector on the second movable bracket 3151 for connecting to the second lens 210 or the second mechanism 220 includes: a second focusing bracket 3154 and a second connecting rod 3155.
[0259] The first end of the second focusing bracket 3154 passes through the fixed plate 13 and is connected to the second movable bracket 3151. The second end is connected to the first end of the second connecting rod 3155. The second end of the second connecting rod 3155 is connected to the second lens 210 or the second mechanism 220.
[0260] In the embodiments of this application, the first end of the second focusing bracket 3154 passes through the fixing plate 13, so that the fixing plate 13 can restrict the rotation of the second focusing bracket 3154 and the second movable bracket 3151 around the second focusing axis 360, thereby converting the rotation of the second curved cylinder 316 into the axial movement of the second movable bracket 3151, the second focusing bracket 3154 and the second connecting rod 3155, avoiding the shaking of the second connecting rod 3155 caused by restricting the rotation only by the lens or the movement, and thus avoiding affecting the focusing accuracy and the life of the second connecting rod 3155.
[0261] The first connecting rod 314 and the second connecting rod 3155 are respectively located on both sides of the second focusing shaft 360, and are spaced apart from the second focusing shaft 360, so that the first connecting rod 314 and the second connecting rod 3155 will not interfere with each other during the focusing process.
[0262] The specific structures of the first connecting rod 314 and the second connecting rod 3155 can be compared with those of the second connecting rod 3155. Figure 16 and Figure 17 The connecting rod 3122 shown is the same, and will not be described again here.
[0263] like Figure 21 As shown, the focusing operation component 300 also includes a second limit guide rod 392.
[0264] The second limiting guide rod 392 is disposed in the receiving cavity 11 of the housing 10, arranged in a direction parallel to the optical axis, and fixedly connected to the housing 10, specifically, it can be fixedly connected to the fixing plate 13. The first focusing bracket 313 and the second focusing bracket 3154 are both slidably sleeved on the second limiting guide rod 392.
[0265] In the embodiments of this application, a second limiting guide rod 392 is fixedly connected to the housing 10, which can restrict the rotation of the first focusing bracket 313 and the second focusing bracket 3154 and guide the axial movement of the first focusing bracket 313 and the second focusing bracket 3154, so that the first focusing bracket 313 and the second focusing bracket 3154 always move along the axial direction, thus ensuring high focusing accuracy.
[0266] The specific structure and arrangement of the second limiting guide rod 392 can be the same as the aforementioned first limiting rod 391, and will not be repeated here.
[0267] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
