Description

A binocular handheld device

[0001] This application claims priority to Chinese Patent Application No. 202411446028.8, filed on October 16, 2024, entitled "A Binocular Handheld Device", and Chinese Patent Application No. 202422503739.6, filed on October 16, 2024, entitled "A Binocular Handheld Device and Focusing Component", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of imaging equipment technology, and more specifically, to a binocular handheld device. Background Technology

[0003] Common binocular handheld devices offer two lens options: a focusing lens and a fixed-focus lens. The focusing lens contains a focusing element that can move back and forth along the optical axis. This focusing element can be electrically or manually driven to achieve either motorized or manual focusing. Motorized focusing involves a motor moving the focusing element back and forth, while manual focusing involves adjusting a flange to move the focusing element back and forth to achieve focus.

[0004] Electric focusing offers high automation and saves time and effort, but the need for a motor complicates the structure of handheld devices, resulting in excessive space occupation and heavy lenses. Manual focusing is simpler than electric focusing, primarily employing two layouts: a lens focusing ring and a separate focusing wheel. However, when using a lens focusing ring, it is usually located far from the handheld part, requiring the user to move their hand back and forth, leading to a poor user experience. A separate focusing wheel can be arranged according to the specific product requirements, but the separate focusing wheels for the two lenses in binocular handheld devices are not only detrimental to the overall product layout but also inconvenient for users operating with either hand.

[0005] In summary, how to effectively solve the problem of limited focusing structure layout in binocular handheld devices is a problem that needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0045] This invention discloses a binocular handheld device for conveniently adjusting the focal length of a first lens and a second lens.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In some embodiments, please refer to Figures 1-5. The binocular handheld device provided by the present invention includes a first lens barrel assembly 2 and a second lens barrel assembly 3 respectively disposed for each binocular, and a focusing assembly 1 disposed between the first lens barrel assembly 2 and the second lens barrel assembly 3.

[0048] The first lens barrel assembly 2 includes a first lens 21, a first lens barrel 22, and a first mechanism 23 disposed within the first lens barrel 22, and the first mechanism 23 is movable back and forth along the optical axis of the first lens 21. The second lens barrel assembly 3 includes a second lens 31, a second lens barrel 32, and a second mechanism 33 disposed within the second lens barrel 32, and the second mechanism 33 is movable back and forth along the optical axis of the second lens 31, wherein the optical axes of the first lens 21 and the second lens 31 are parallel. The first mechanism 23 and the second mechanism 33 are respectively used for image detection, specifically for processing light entering through the lens to generate image data and send it to the display for image display, so that the user can observe through the eyepiece of the handheld device. For the specific structure and working principle of the first mechanism 23 and the second mechanism 33, please refer to conventional handheld devices, which will not be repeated here. The first mechanism 23 is movable back and forth along the optical axis of the first lens 21, and the second mechanism 33 is movable back and forth along the optical axis of the second lens 31. For ease of explanation, in the following embodiments, the direction in which the mechanism moves closer to the corresponding lens is referred to as forward, and the opposite is referred to as backward. Unlike conventional camera mechanisms that are fixedly installed inside the housing of a handheld device, the camera mechanism in this application can move back and forth along the optical axis of the lens within the housing, thereby changing the distance between the lens and the corresponding camera mechanism to achieve focus adjustment and clear imaging.

[0049] Since the focus adjustment in this application no longer relies on the forward and backward movement of the focusing lenses in the first lens 21 and the second lens 31, both lenses of the first lens 21 and the second lens 31 can be fixedly mounted. The types of the first lens 21 and the second lens 31 are not specifically limited here; they can both be dual-beam lenses, such as those capable of dual-beam fusion, including but not limited to infrared lenses and low-light lenses, such as a combination of an infrared lens and a starlight night vision lens. Depending on the needs, they can also use the same type of lens, such as both being infrared lenses, in which case separate focus adjustment can be used to meet different usage requirements.

[0050] The focusing assembly 1 provided in this application includes a first focusing wheel 111 and a second focusing wheel 112 coaxially arranged and sequentially distributed along the axial direction. The first focusing wheel 111 can rotate around the axial direction and drive the first camera mechanism 23 to move back and forth, thereby changing the distance between the first camera mechanism 23 and the first lens 21. The second focusing wheel 112 can rotate around the axial direction and drive the second camera mechanism 33 to move back and forth, thereby changing the distance between the second camera mechanism 33 and the second lens 31. It is understood that the front-to-back positional relationship of the first focusing wheel 111 and the second focusing wheel 112 in the axial direction is not limited here. The first focusing wheel 111 being located behind the second focusing wheel 112 in Figure 1 is only an example of one layout. In other embodiments, the first focusing wheel 111 may also be located in front of the second focusing wheel 112. The first focusing wheel 111, the first lens 21, and the first camera mechanism 23 form a group, and the second focusing wheel 112, the second lens 31, and the second camera mechanism 33 form a group. The first focusing wheel 111 can rotate around its axis and drive the first camera mechanism 23 to move back and forth, thereby changing the distance between the first camera mechanism 23 and the first lens 21, and achieving independent focusing of the first lens 21. The second focusing wheel 112 can rotate around its axis and drive the second camera mechanism 33 to move back and forth, thereby changing the distance between the second camera mechanism 33 and the second lens 31, and achieving independent focusing of the second lens 31. That is, when the first focusing wheel 111 is rotated independently, the second focusing wheel 112 can remain stationary. Correspondingly, when the second focusing wheel 112 is rotated independently, the first focusing wheel 111 can remain stationary.

[0051] When using the binocular handheld device provided by this invention, to focus the first lens 21 and the second lens 31 separately, the first focusing wheel 111 and the second focusing wheel 112 are rotated accordingly. The first focusing wheel 111 drives the first mechanism 23 to move back and forth, and the second focusing wheel 112 drives the second mechanism 33 to move back and forth, changing the distance between the first mechanism 23 and the first lens 21, as well as the distance between the second mechanism 33 and the second lens 31, thus achieving individual focus adjustment of the first lens 21 and the second lens 31. In this binocular handheld device, the rotation axes of the first focusing wheel 111 and the second focusing wheel 112 are coaxial and sequentially distributed along the axial direction, resulting in a simple and compact structure that avoids motion interference and facilitates user operation. In addition, the first focusing wheel 111 and the second focusing wheel 112 drive the corresponding first movement 23 and the second movement 33 to move back and forth. Compared with the conventional method of driving the first lens 21 and the second lens 31, the positions of the first focusing wheel 111 and the second focusing wheel 112 can be closer to the hand part of the device. Therefore, when the user holds the device and adjusts the focus, the hand does not need to move back and forth, and the focus adjustment operation is more convenient.

[0052] Furthermore, the first focusing wheel 111 and the second focusing wheel 112 are located between the first lens barrel 22 and the second lens barrel 32, allowing for convenient operation with either the user's left or right hands. This arrangement also makes efficient use of the space between the first lens barrel 22 and the second lens barrel 32, facilitating the control of the overall size of the handheld device.

[0053] In some embodiments, referring to Figures 5-7, the focusing assembly 1 provided in this application includes a first rotating shaft 121 disposed on a first focusing wheel 111, the first rotating shaft 121 being coaxial with the first focusing wheel 111. The focusing assembly 1 also includes a second rotating shaft 122 disposed on a second focusing wheel 112, the second rotating shaft 122 being coaxial with the second focusing wheel 112, the second rotating shaft 122 being sleeved outside the first rotating shaft 121 and capable of relative rotation. The focusing assembly 1 also includes a first moving member 131 cooperating with the first rotating shaft 121, the rotation of the first rotating shaft 121 being convertible into the back-and-forth movement of the first moving member 131, and the first moving member 131 being connected to the first movement mechanism 23; the focusing assembly 1 also includes a second moving member 132 cooperating with the second rotating shaft 122, the rotation of the second rotating shaft 122 being convertible into the back-and-forth movement of the second moving member 132, and the second moving member 132 being connected to the second movement mechanism 33. It is understandable that the first rotating shaft 121 and the first focusing wheel 111 can be two separate components connected by a conventional fixing method, or they can be an integrated structure. The first moving part 131 is connected to the first movement 23, either directly or indirectly through other components. Correspondingly, the second rotating shaft 122 and the second focusing wheel 112 can be two separate components connected by a conventional fixing method, or they can be an integrated structure. The second moving part 132 is connected to the second movement 33, either directly or indirectly through other components. The first focusing wheel 111 is connected to the first movement 23 via the first rotating shaft 121 and the first moving part 131. When the first focusing wheel 111 rotates, the first rotating shaft 121 rotates synchronously, and the rotation of the first rotating shaft 121 is converted into linear movement of the first moving part 131, which in turn drives the first movement 23 to move back and forth. Through the cooperation of the first rotating shaft 121 and the first moving part 131, not only can the motion mode be converted from rotation to linear movement, but the force of the first focusing wheel 111 can also be transmitted. The length and shape of the first moving part 131 allow for a more flexible relative arrangement of the first focusing wheel 111 and the first mechanism 23, thus making the layout of the first focusing wheel 111 on the handheld device more flexible. The function of the second focusing wheel 112 is the same as that of the first focusing wheel 111, and will not be described further here.

[0054] When focusing the first lens 21 and the second lens 31 separately is required, rotating the first focusing wheel 111 causes the first rotating shaft 121 on the first focusing wheel 111 to rotate accordingly. The first rotating shaft 121 cooperates with the first moving component 131 to convert the rotation of the first rotating shaft 121 into the forward and backward movement of the first moving component 131. The first moving component 131 drives the first camera mechanism 23 to move forward and backward, thereby changing the distance between the first camera mechanism 23 and the first lens 21, thus achieving individual focus adjustment of the first lens 21. Similarly, rotating the second focusing wheel 112 causes the second rotating shaft 122 on the second focusing wheel 112 to rotate accordingly. The second rotating shaft 122 cooperates with the second moving component 132 to convert the rotation of the second rotating shaft 122 into the forward and backward movement of the second moving component 132. The second moving component 132 drives the second camera mechanism 33 to move forward and backward, thereby changing the distance between the second camera mechanism 33 and the second lens 31, thus achieving individual focus adjustment of the second lens 31.

[0055] The focusing assembly, through the length and shape of the first moving part 131 and the second moving part 132, makes the relative position of the first focusing wheel 111 and the first mechanism 23 and the phase position of the second focusing wheel 112 and the second mechanism 33 more flexible, thereby making the layout of the first focusing wheel 111 and the second focusing wheel 112 more flexible on the binocular handheld device.

[0056] In some embodiments, the first rotating shaft 121 and the first moving member 131 are threadedly engaged. The rotation of the first rotating shaft 121 is converted into linear movement of the first moving member 131 through this threaded engagement. It is understood that the first rotating shaft 121 can rotate about its axial direction, and its linear movement along the axial direction is limited, thereby enabling the conversion of the rotation of the first rotating shaft 121 into axial movement of the first moving member 131 through the threaded engagement. The threaded engagement provides high adjustment accuracy, convenient assembly, and a simple and compact structure. Specifically, the first rotating shaft 121 is a lead screw with external threads, and the first moving member 131 is a nut threadedly connected to the lead screw. When the lead screw rotates, the nut can move linearly along the lead screw.

[0057] In other embodiments, the first rotating shaft 121 is a rotating rod, and the first moving member 131 is a moving ring sleeved on the rotating rod. One of the inner wall of the moving ring and the outer wall of the rotating rod has a groove, and the other has a guide protrusion inserted into the groove. This embodiment differs from the threaded connection between the first rotating shaft 121 and the first moving member 131 described above in that, by providing a groove on one of the mating surfaces of the rotating rod and the moving ring, and a guide protrusion on the other, the path of the groove allows the rotating rod to rotate, causing the moving ring to move linearly via the guide protrusion, thereby causing the first mechanism 23 to move linearly. The use of a groove and guide protrusion results in a simple structure and ease of manufacturing.

[0058] In some embodiments, the second rotating shaft 122 and the second moving member 132 are threaded together. Alternatively, the second rotating shaft 122 and the second moving member 132 can also be engaged by a groove and a guide protrusion. Specific engagement methods can be found in the first rotating shaft 121 and the first moving member 131 in the above embodiments, and will not be repeated here.

[0059] In some embodiments, the focusing assembly 1 further includes a first connector 141, one end of which is disposed on the first moving member 131 and the other end on the first movement 23. That is, the first moving member 131 and the first movement 23 are connected via the first connector 141. The shape and size of the first connector 141 are configured according to the position of the first movement 23 within the first lens barrel 22 and the position of the first focusing wheel 111. The first connector 141 further enhances the flexibility of the layout of the first focusing wheel 111.

[0060] In some embodiments, the focusing assembly 1 further includes a second connector 142, one end of which is disposed on the second moving member 132 and the other end on the second movement 33. The second connector 142 also improves the flexibility of the layout of the second focusing wheel 112. Specifically, the structure of the second connector 142 can be the same as or different from that of the first connector 141, depending on the layout of the first movement 23 and the second movement 33 and the internal space of the first lens barrel 22 and the second lens barrel 32.

[0061] In some embodiments, the first connecting member 141 includes a first pull rod 1411 and a first support arm 1412. One end of the first pull rod 1411 is connected to the first moving member 131, and the other end is connected to one end of the first support arm 1412. The other end of the first support arm 1412 is connected to the first movement mechanism 23. The first pull rod 1411 is parallel to the axial direction of the first rotating shaft 121, and at least a portion of the first support arm 1412 is perpendicular to the axial direction of the first rotating shaft 121. It is understood that the first pull rod 1411 and the first support arm 1412 can be separate components connected by a conventional fixing method, or they can be an integral structure. With the first pull rod 1411 parallel to the axial direction of the first rotating shaft 121 and at least a portion of the first support arm 1412 perpendicular to the axial direction of the first rotating shaft 121, the first movement mechanism 23 and the first focusing wheel 111 can be offset in both the axial and perpendicular directions, making the spatial arrangement of the first focusing wheel 111 more flexible and less restricted. Specifically, the first focusing wheel 111 and the second focusing wheel 112 are positioned close to the first eyepiece 4 and the second eyepiece 5 of the binocular handheld device. The first lever 1411 and the first support arm 1412 facilitate the connection between the first focusing wheel 111 and the first camera module 23, while the second lever 1421 and the second support arm 1422 facilitate the connection between the second focusing wheel 112 and the second camera module 33. This configuration, with the first focusing wheel 111 and the second focusing wheel 112 positioned close to the grip of the handheld device, makes operation more convenient and reduces the weight of the lens end of the handheld device, providing a better user experience.

[0062] In some embodiments, the second connector 142 may also have the same configuration as the first connector 141. Specifically, the second connector 142 includes a second pull rod 1421 and a second support arm 1422. One end of the second pull rod 1421 is connected to the second moving member 132, and the other end is connected to one end of the second support arm 1422. The other end of the second support arm 1422 is connected to the second mechanism 33. The second pull rod 1421 is parallel to the axial direction of the second rotating shaft 122, and at least a portion of the second support arm 1422 is perpendicular to the axial direction of the second rotating shaft 122. Specifically, the length of the second pull rod 1421 and the length of the first pull rod 1411 may be the same or different, and the length of the second support arm 1422 and the length of the first support arm 1412 may be the same or different.

[0063] In some embodiments, referring to FIG8, the first support arm 1412 includes a main body 1412a and a cross plate 1412b extending axially perpendicularly from the main body 1412a. The main body 1412a is used to connect with the first mechanism 23. When the first mechanism 23 is mounted on the first bracket 91, the main body 1412a is connected to the first bracket 91. Specifically, one end of the main body 1412a contacts the end face of the first bracket 91 for positioning, and the main body 1412a is provided with screw holes and is locked to the first bracket 91 by screws. The main body 1412a is specifically in the shape of a right-angled triangle, and the screw holes are opened on the end face corresponding to the hypotenuse of the right-angled triangle. The end face corresponding to one right-angled side contacts the first bracket 91. As described above, a reliable connection is achieved while reducing the volume, thereby reducing space occupation. Furthermore, a connecting plate 1412c is provided between the cross plate 1412b and the main body 1412a. The connecting plate 1412c can play a reinforcing role to prevent the cross plate 1412b from deforming. It is understood that the first arm 1412 can be a one-piece structure, that is, the aforementioned horizontal plate 1412b, main body 1412a, and connecting plate 1412c can be integrally formed. The second arm 1422 can adopt the same configuration as the first arm 1412, which will not be described in detail here.

[0064] In some embodiments, please refer to FIG7, a first rotating shaft 121 passes through a first focusing wheel 111 and a second focusing wheel 112, and a second rotating shaft 122 is sleeved outside the first rotating shaft 121. The outer peripheral surface of the first rotating shaft 121 is provided with a flange 1211, and the front end of the second rotating shaft 122 faces the flange 1211. The tail end of the first rotating shaft 121 is connected to a first locking member 151 that abuts against the first focusing wheel 111, and the front end of the first rotating shaft 121 is connected to a second locking member 152. The second locking member 152 is provided with a locking platform 1521, which is opposite to the front end of the first rotating shaft 121 and is used to abut against the housing of the handheld device to limit the axial displacement of the first rotating shaft 121. Combined with the flange 1211 provided on the first rotating shaft 121, it can cooperate with the second rotating shaft 122 to limit the axial movement of the second rotating shaft 122, thereby limiting the axial movement of both the first rotating shaft 121 and the second rotating shaft 122. Consequently, the axial movement of the first focusing wheel 111 and the second focusing wheel 112 is also limited, and they can only rotate around the axial direction and cannot move linearly. During installation, the first rotating shaft 121 is inserted into the second rotating shaft 122. The first focusing wheel 111 and the second focusing wheel 112 are respectively sleeved on the first rotating shaft 121 and the second rotating shaft 122 and fixedly connected. Then, the first locking member 151 is connected to the tail end of the first rotating shaft 121 and abuts against the first focusing wheel 111 for axial limiting. The whole assembly is then placed in a suitable position within the housing. The second locking member 152 is connected to the front end of the first rotating shaft 121. The housing portion is then clamped between the locking platform 1521 and the front end of the first rotating shaft 121, with the second rotating shaft 122 abutting against the flange 1211. Thus, the axial directions of both the first rotating shaft 121 and the second rotating shaft 122 are reliably limited. This configuration achieves axial limiting of the first rotating shaft 121 and the second rotating shaft 122, thereby also achieving axial limiting of the first focusing wheel 111 and the second focusing wheel 112. Furthermore, the structure is simple and compact, and assembly is convenient.

[0065] Specifically, the first locking element 151 can be a nut, which is threadedly connected to the tail end of the first rotating shaft 121, with the end face of the nut pressing against the first focusing wheel 111. The end face of the first focusing wheel 111 can be provided with a countersunk hole, and the nut is placed inside the countersunk hole, with the end face of the nut not extending beyond the end face of the first focusing wheel 111, resulting in a cleaner and more aesthetically pleasing appearance for the binocular handheld device. The second locking element 152 can be threadedly connected to the first rotating shaft 121. Threaded connections facilitate disassembly and assembly, and the screw-in / screw-out length of the second locking element 152 is adjustable, allowing for better adaptation to the housing and ensuring reliable positioning.

[0066] In some embodiments, a thrust ball bearing 161 is provided between the front end of the second rotating shaft 122 and the flange 1211. By providing the thrust ball bearing 161, direct contact friction between the second rotating shaft 122 and the flange 1211 is avoided, reducing the frictional resistance when the first rotating shaft 121 rotates independently with the first focusing wheel 111 and when the second rotating shaft 122 rotates independently with the second focusing wheel 112, facilitating focus adjustment by the user and preventing frictional wear. In other embodiments, the thrust ball bearing 161 may not be provided; for example, by providing a smooth, wear-resistant coating on the surfaces of the second rotating shaft 122 that contact the flange 1211, the friction-reducing effect can also be achieved.

[0067] In some embodiments, the focusing assembly 1 provided in this application further includes a spacer 171, with the first focusing wheel 111 and the second focusing wheel 112 rotatably disposed at their respective front and rear ends. By providing the spacer 171 between the first focusing wheel 111 and the second focusing wheel 112, the two are separated, allowing the first focusing wheel 111 and the second focusing wheel 112 to rotate independently without affecting each other. Simultaneously, the spacer 171 can also integrate the first focusing wheel 111 and the second focusing wheel 112 into a single unit, facilitating the rotational installation of the first focusing wheel 111 and the second focusing wheel 112 within the housing. Specifically, the spacer 171 is provided with a fixing part 1714, such as a bolt hole, for fixed connection with the housing, thereby realizing the installation of the focusing assembly 1 and the housing. The spacer 171 specifically includes a protrusion extending from the outer peripheral surface of the first focusing wheel 111 and the second focusing wheel 112, with the fixing part 1714, such as a bolt hole, disposed on the protrusion.

[0068] In some embodiments, the isolation member 171 includes an intermediate plate 1711, one end face of which is provided with a first protrusion 1712 or a first annular groove, and the other end face of which is provided with a second protrusion 1713 or a second annular groove; the first focusing wheel 111 is provided with a first limiting groove 1111 that cooperates with the first protrusion 1712 or a first limiting protrusion that cooperates with the first annular groove; the second focusing wheel 112 is provided with a second limiting groove 1121 that cooperates with the second protrusion 1713 or a second limiting protrusion that cooperates with the second annular groove. The first focusing wheel 111 and the second focusing wheel 112 are distributed sequentially along the axial direction. When the first focusing wheel 111 is located after the second focusing wheel 112, the rear end face of the intermediate plate 1711 is provided with a first protrusion 1712 or a first annular groove, and the front end face of the intermediate plate 1711 is provided with a second protrusion 1713 or a second annular groove. When the positions of the first focusing wheel 111 and the second focusing wheel 112 are interchanged, the front end face of the corresponding intermediate plate 1711 is provided with a first protrusion 1712 or a first annular groove, and the rear end face of the intermediate plate 1711 is provided with a second protrusion 1713 or a second annular groove.

[0069] In one embodiment, a first protrusion 1712 is provided on one end face of the intermediate plate 1711, and a first limiting groove 1111 is provided on the first focusing wheel 111 to cooperate with the first protrusion 1712. The first protrusion 1712 is inserted into the first limiting groove 1111. Both the first protrusion 1712 and the first limiting groove 1111 are annular to limit and guide, which facilitates the installation of the first focusing wheel 111 and the isolation member 171, and guides the first focusing wheel 111 when it rotates.

[0070] In another embodiment, one end face of the intermediate plate 1711 is provided with a first annular groove, and the first focusing wheel 111 is provided with a first limiting protrusion that cooperates with the first annular groove. The first limiting protrusion is inserted into the first annular groove to play a limiting and guiding role, which facilitates the installation of the first focusing wheel 111 and the isolation member 171, and guides the first focusing wheel 111 when it rotates.

[0071] The engagement between the isolator 171 and the second focusing wheel 112 can be similar to that described above, and will not be repeated here. It is understood that both ends of the intermediate plate 1711 can be provided with protrusions (first protrusion 1712 and second protrusion 1713) or both can be provided with annular grooves (first annular groove and second annular groove), or one can be provided with a protrusion and the other with an annular groove (first protrusion 1712 and second annular groove, or first annular groove and second protrusion 1713).

[0072] Specifically, a first sealing ring 181 is provided between the first protrusion 1712 and the first limiting groove 1111, and a second sealing ring 182 is provided between the second protrusion 1713 and the second limiting groove 1121, so as to achieve sealing of the first focusing wheel 111 and the second focusing wheel 112.

[0073] In some embodiments, the binocular handheld device further includes a first bracket 91 and a first linear guide rail 92. The first mechanism 23 is mounted on the first bracket 91; the first linear guide rail 92 includes a guide rail and a slider slidably mounted on the guide rail. One of the guide rail and the slider is connected to the first bracket 91, and the other is used to connect to the housing of the binocular handheld device. It is understood that the other of the guide rail and the slider can be directly fixed to the housing or fixed to the first lens 21 connected to the housing, i.e., indirectly connected to the housing, depending on the internal layout of the housing. The first bracket 91 serves to install and protect the first mechanism 23; its specific structure can be configured as needed and is not specifically limited here. It is understood that the guide rail of the first linear guide rail 92 is parallel to the axial direction of the first mechanism 23. By setting the first linear guide rail 92, the linear movement of the first mechanism 23 can be limited and guided, ensuring its coaxiality with the first lens 21 and reducing the resistance to the movement of the first mechanism 23 relative to the first lens 21.

[0074] In some embodiments, the binocular handheld device further includes a second bracket 93 and a second linear guide rail 94. The second mechanism 33 is mounted on the second bracket 93; the second linear guide rail 94 includes a guide rail and a slider slidably mounted on the guide rail. One of the guide rail and the slider of the second linear guide rail 94 is connected to the second bracket 93, and the other is used to connect to the housing of the binocular handheld device. By providing the second linear guide rail 94, the linear movement of the second mechanism 33 can be limited and guided, ensuring its coaxiality with the second lens 31.

[0075] In some embodiments, as shown in Figures 1-4, the binocular handheld device has a first eyepiece 4 at one end of the first lens barrel 22 and a second eyepiece 5 at one end of the second lens barrel 32. A first focusing wheel 111 and a second focusing wheel 112 are located between the first lens barrel 22 and the second lens barrel 32, and are close to the first eyepiece 4 and the second eyepiece 5. The proximity of the first focusing wheel 111 and the second focusing wheel 112 to the grip position of the handheld device makes operation more convenient, reduces the weight of the lens end of the handheld device, and provides a better user experience when focusing the device.

[0076] In some embodiments, as shown in Figures 1-4, a supplementary light 6 is also provided between the first lens barrel assembly 2 and the second lens barrel assembly 3, and the supplementary light 6 is located in front of the focusing assembly 1. By providing the supplementary light 6, supplementary lighting can be provided when the binocular handheld device is in use to meet the needs of use in special environments. For example, the supplementary light 6 is coaxially arranged with the focusing assembly 1 to make reasonable use of space and make the overall shape of the binocular handheld device more neat.

[0077] In some embodiments, as shown in Figures 1-4, a battery compartment 7 for accommodating a battery is provided on the side of the first lens barrel 22 or the second lens barrel 32. The battery is used to power the binocular handheld device, such as the first mechanism 23 and the second mechanism 33. By placing the battery compartment 7 on the side of the first lens barrel 22 or the second lens barrel 32, space is efficiently utilized. This also allows for convenient battery replacement or maintenance as needed.

[0078] In some embodiments, as shown in Figures 1-4, the top surface of the first lens barrel 22 and / or the second lens barrel 32 is provided with function keys 8. The function keys 8 include at least one of a power button 81, a menu button 82, an up button 83, and a down button 84. By placing the function keys 8 for controlling the binocular handheld device on the top surface of the first lens barrel 22, or the top surface of the second lens barrel 32, or both on the top surfaces of the first lens barrel 22 and the second lens barrel 32, the user can easily operate them with either hand, such as by operating each function key 8 with either hand.

[0079] In some embodiments, one of the first lens 21 and the second lens 31 is a visible light lens and the other is an infrared lens.

[0080] The following is a specific embodiment illustrating the assembly method of the binocular handheld device provided in this application.

[0081] In this embodiment, the assembly can be performed according to the following steps:

[0082] Step 1: The first rotating shaft 121 and the first moving part 131, the second rotating shaft 122 and the second moving part 132 cooperate with each other and are coaxially assembled through the thrust ball bearing 161.

[0083] Step 2: The second pull rod 1421 is locked and fixed to the second moving part 132 by screws. Similarly, the first pull rod 1411 is locked and fixed to the first moving part 131 by screws to transmit the pulling (pushing) force.

[0084] Step 3: The second focusing wheel 112 is fitted into the above assembly and the second focusing wheel 112 is fixed to the second rotating shaft 122 by screws; then the isolation member 171 and the first focusing wheel 111 are fitted in sequence. The isolation member 171 is fixed to the housing by screws, and one end of the first focusing wheel 111 is locked and fixed to the first rotating shaft 121 by the first limiting member.

[0085] Step 4: The other end of the first rotating shaft 121 engages with the second limiting member through a thread, restricting the forward and backward movement of the assembled components.

[0086] Step 5: The first pull rod 1411 is fastened to the first support arm 1412 by screws, and the second pull rod 1421 is fastened to the second support arm 1422 by screws to transmit the pulling / pushing force.

[0087] Step 6: The first mechanism 23 and the first bracket 91 are fixed and locked with screws. At the same time, the first bracket 91 is fixed to one side of the first linear guide rail 92, and the other side of the first linear guide rail 92 is fixed with a linear guide rail bracket. The linear guide rail bracket is locked and fixed to the first lens 21 or the housing. The second mechanism 33, the second bracket 93, and the second linear guide rail 94 are fixed in the same way.

[0088] Step 7: The first bracket 91 and the first arm 1412 are fixedly connected by screws; the second bracket 93 and the second arm 1422 are fixedly connected by screws.

[0089] When focusing, when the user rotates the first focusing wheel 111, the first rotating shaft 121 rotates accordingly, which is converted into linear movement of the first moving component 131. This movement, via the first pull rod 1411, the first support arm 1412, and the first bracket 91, drives the first mechanism 23 to move back and forth, thereby achieving the function of focusing the first lens 21. When the user rotates the second focusing wheel 112, the second rotating shaft 122 rotates accordingly, which is converted into linear movement of the second moving component 132. The second moving component 132 drives the second pull rod 1421 to move back and forth. The second pull rod 1421, via the second support arm 1422 and the second bracket 93, drives the second mechanism 33 to move back and forth, thereby achieving the function of focusing the second lens 31.

[0090] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0091] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
