[0032] Currently, handheld observation equipment includes monocular handheld observation equipment and binocular handheld observation equipment. Monocular handheld observation equipment can only perform monocular observation and cannot perform binocular observation, making it inconvenient to use. Although binocular handheld observation equipment can perform binocular observation, it is usually an integrated whole structure, and its two tubes cannot be disassembled, so it cannot perform monocular observation and has low flexibility of use.

[0033] In view of this, the present disclosure provides a handheld observation device aimed at solving the technical problem of low flexibility in the use of existing handheld observation devices.

[0034] As shown in Figures 1 to 4, the handheld observation device includes a monocular observation component 10 and a connecting structure 20. Two monocular observation components 10 are arranged side-by-side along a first direction. Each monocular observation component 10 includes a body 11 and an eyepiece 12. The body 11 extends along a second direction, different from the first direction, and the eyepiece 12 is disposed on one end of the body 11 along the second direction. The connecting structure 20 is located between the two monocular observation components 10, detachably connecting them to form a binocular handheld observation device. At least one monocular observation component 10 can move relative to the connecting structure 20 along the first direction to adjust the distance between the two eyepieces 12. The distance between the two eyepieces 12 refers to the distance between the centers of the two eyepieces 12.

[0035] In one embodiment, the first direction is the left-right direction shown in Figure 1, and the second direction is the front-back direction shown in Figure 1. In the handheld observation device, two monocular observation components 10 are arranged side by side along the left-right direction so that the user can observe with both eyes, which conforms to ergonomic design. Each monocular observation component 10 includes a main body 11 and an eyepiece 12. The main body 11 extends along the front-back direction, and the eyepiece 12 is located at the front end of the main body 11.

[0036] In use, the handheld observation device of this embodiment can be used as a monocular handheld observation device by detaching the monocular observation component 10 from the connecting structure 20, thus separating the two monocular observation components 10. When the two monocular observation components 10 are assembled together via the connecting structure 20, they can also be used as a binocular handheld observation device. Therefore, this handheld observation device is flexible and convenient to use. Furthermore, when the two monocular observation components 10 are assembled together via the connecting structure 20, at least one monocular observation component 10 can move relative to the connecting structure 20 along the first direction to adjust the distance between the two eyepieces 12.

[0037] In one embodiment, both monocular observation components 10 are movable relative to the connecting structure 20 in the left-right direction, allowing them to move closer or further apart, thereby adjusting the distance between the two eyepieces 12 to accommodate different interpupillary distances. Therefore, this handheld observation device is flexible, convenient, and highly adaptable.

[0038] In another embodiment, one of the two monocular observation components 10 can move relative to the connecting structure 20 in the left-right direction, moving it closer to or further away from the other monocular observation component 10 in the left-right direction, thereby adjusting the distance between the two eyepieces 12 to adapt to different interpupillary distances. Therefore, this handheld observation device is flexible, convenient, and has good applicability.

[0039] In one embodiment, the connection structure 20 includes a rotating shaft 21 and two movable blocks 22. The rotating shaft 21 extends along a second direction, and the two movable blocks 22 are arranged opposite to each other along a first direction and are detachably connected to two monocular observation components 10 respectively. At least one movable block 22 is rotatably connected to the rotating shaft 21, so that the corresponding monocular observation component 10 can rotate around the rotating shaft 21 to adjust the distance between the two eyepieces 12.

[0040] As shown in Figures 1, 3, and 4, the rotating shaft 21 extends in the front-to-back direction, and the two movable blocks 22 are positioned opposite each other in the left-to-right direction. The movable block 22 on the left side and the monocular observation component 10 on the same side are detachably connected, as are the movable block 22 on the right side and the monocular observation component 10 on the same side, facilitating assembly and disassembly. To accommodate different users' interpupillary distances, at least one movable block 22 can be rotatably connected to the rotating shaft 21, allowing the corresponding monocular observation component 10 to rotate clockwise or counterclockwise around the rotating shaft 21, thereby adjusting the distance between the two eyepieces 12.

[0041] In one embodiment, the two sides of the movable block 22 along the first direction are a first connecting side 221 and a second connecting side 222, respectively. The first connecting side 221 of at least one movable block 22 is rotatably sleeved on the rotating shaft 21, and the second connecting side 222 is detachably connected to the corresponding monocular observation component 10, so as to realize the assembly and disassembly of the movable block 22 and the monocular observation component 10 arranged on the same side.

[0042] Two limiting members 211 are respectively provided at both ends of the rotating shaft 21 along the second direction, that is, at the front and rear ends of the rotating shaft 21. The movable block 22 is located between the two limiting members 211. The two limiting members 211 respectively abut the two ends of the movable block 22 along the second direction, thereby limiting the movable block 22 along the front and rear direction through the cooperation of the two limiting members 211, improving the assembly stability of the movable block 22 and the rotating shaft 21. During the process of the user rotating the monocular observation component 10 around the rotating shaft 21, due to the abutment between each limiting member 211 and the movable block 22, the limiting members 211 and the movable block 22 are in frictional engagement, so that the user needs to apply a certain torque to rotate the monocular observation component 10. This not only improves the user's feel, but also provides a certain locking force by the friction between the limiting members 211 and the movable block 22 after the monocular observation component 10 is rotated to a suitable angle, so that the monocular observation component 10 can stay at a suitable angle, ensuring that the distance between the two eyepieces 12 does not change arbitrarily after being adjusted.

[0043] Furthermore, a sleeve 223 is provided on the first connecting side 221 of one of the two movable blocks 22, and the sleeve 223 is rotatably sleeved on the rotating shaft 21; two collars 224 are respectively provided at both ends of the first connecting side 221 of the other movable block 22 along the second direction, the sleeve 223 is pressed against the two collars 224, both collars 224 are rotatably sleeved on the rotating shaft 21, and the two collars 224 are located between the two limiting members 211 and are pressed against the two limiting members 211 respectively.

[0044] Specifically, as shown in Figures 1 to 4, a sleeve 223 is provided on the first connecting side 221 of the movable block 22 on the left side. The sleeve 223 is rotatably fitted onto the rotating shaft 21 to allow the movable block 22 on the left side to rotate around the rotating shaft 21. Two collars 224 are provided at both ends of the first connecting side 221 of the movable block 22 on the right side, i.e., its front and rear ends, respectively. Both collars 224 are rotatably fitted onto the rotating shaft 21 to allow the movable block 22 on the right side to rotate around the rotating shaft 21. Thus, rotating either monocular observation component 10 or simultaneously rotating both monocular observation components 10 can adjust the distance between the two eyepieces 12, making it flexible and convenient to use. The front and rear ends of the sleeve 223 are respectively pressed against the two collars 224, allowing the front and rear ends of the sleeve 223 to engage with the two collars 224 through friction. This further increases the torque required for the user to rotate the monocular observation component 10, thereby improving the user experience and ensuring that the distance between the two eyepieces 12 remains stable after adjustment and does not change arbitrarily. In one embodiment, both the sleeve 223 and the rotating shaft 21 are provided with threading holes 212 for easy passage of wire harnesses, which is a reasonable design.

[0045] Furthermore, the two limiting components 211 are a limiting plate 211a and a limiting nut 211b, respectively. The two ends (i.e., the front end and the rear end) of the rotating shaft 21 along the second direction are the first end and the second end, respectively. The two collars 224 are the first collar 224a and the second collar 224b, respectively. The limiting plate 211a is fixed to the first end and abuts against the first collar 224a. The second end of the rotating shaft 21 is provided with a threaded section 213. The limiting nut 211b is sleeved on the second end and threadedly connected to the threaded section 213 and abuts against the second collar 224b.

[0046] The limiting plate 211a is fixed to the front end of the rotating shaft 21 and abuts against the front end face of the first sleeve ring 224a. The limiting nut 211b is threadedly connected to the threaded section 213 at the rear end of the rotating shaft 21, and the limiting nut 211b abuts against the rear end face of the second sleeve ring 224b. Thus, by screwing the limiting nut 211b, the two movable blocks 22 can be abutted against each other from the front and rear directions in conjunction with the limiting plate 211a. This not only makes the operation convenient and flexible, but also improves the assembly stability of the movable block 22 and the rotating shaft 21, while further increasing the torque that the user needs to apply when rotating the monocular observation component 10, thereby providing a better user feel and improving the reliability of the distance between the two eyepieces 12 after it is adjusted to the correct position.

[0047] In one embodiment, a first friction pad 225 is provided between the first collar 224a and the sleeve 223; a second friction pad 226 is provided between the second collar 224b and the sleeve 223; and a friction assembly is provided between the limiting nut 211b and the second collar 224b, the friction assembly including two springs 227 and a pad 228 placed between the two springs 227.

[0048] By setting the first friction pad 225 and the second friction pad 226, the friction between the front and rear ends of the sleeve 223 and the corresponding collar 224 is increased, further improving the user experience. Furthermore, by placing a friction assembly between the limiting nut 211b and the second collar 224b, and the friction assembly including two springs 227 and a pad 228 placed between the two springs 227, the springs 227 can use their elastic force to press the second collar 224b against the sleeve. The front and rear sides of the friction assembly press against the second collar 224b and the limiting nut 211b respectively, increasing the friction. By turning the limiting nut 211b, the deformation of the springs 227 is adjusted, thereby adjusting the elastic force of the springs 227. This change in elastic force adjusts the torque required for the user to rotate the monocular observation component 10, thus adjusting the user experience and the locking force on the movable block 22 after the monocular observation component 10 is rotated to its final position. In one embodiment, the reed 227 may be, but is not limited to, a disc spring.

[0049] In one embodiment, each monocular observation component 10 has a first connector on the side of its main body 11 facing the connecting structure 20; the connecting structure 20 has a second connector at the position corresponding to each first connector, and the first connector and the corresponding second connector are plugged in and engaged.

[0050] As shown in Figures 1 to 6, a first connector is provided on the inner side of the main body 11 of each monocular observation component 10, and a second connector is provided on the second connecting side 222 of each movable block 22. The movable block 22 and the corresponding monocular observation component 10 can be assembled and disassembled through the insertion and cooperation of the first connector and the second connector.

[0051] In one embodiment, the first connector is a slot 30 formed on the main body 11. The second connector is a plug 40 disposed on the connecting structure 20, specifically a plug 40 disposed on the second connecting side 222 of the movable block 22, and the plug 40 is used to engage with the slot 30. This arrangement makes the assembly and disassembly of the movable block 22 and the corresponding monocular observation component 10 simple and convenient, and easy to operate.

[0052] In one embodiment, the connection structure 20 has a contact surface 2221 that matches the shape of the outer wall of the body 11 and contacts the outer wall of the body 11, and the plug 40 is a protrusion 40a that protrudes from the contact surface 2221 in a direction away from the contact surface 2221.

[0053] In one embodiment, the main body 11 of each monocular observation component 10 is cylindrical, forming a monocular lens assembly. The second connecting side 222 of the movable block 22, i.e., the outer side of the movable block 22, has a contact surface 2221. The contact surface 2221 is an arc-shaped surface that matches the shape of the outer wall of the main body 11. This design is reasonable and facilitates assembly with the main body 11. The plug 40 is located on the contact surface 2221 and protrudes from the contact surface 2221 in a direction away from the contact surface 2221, i.e., outward, to form a protrusion 40a for insertion into the slot 30.

[0054] Furthermore, the protrusion 40a is provided with a buckle 41, and the groove wall of the slot 30 has a locking hole 31 for engaging with the buckle 41. The slot opening of the slot 30 faces outward, and the groove wall of the slot 30, specifically the inner groove wall opposite to the slot opening, has a locking hole 31. When the plug 40 is inserted into the slot 30, the buckle 41 engages with the locking hole 31, improving assembly stability.

[0055] The protrusion 40a is also provided with a positioning post 42, which is spaced apart from the latch 41. The groove wall of the slot 30 is also provided with a positioning hole 32 that engages with the positioning post 42. In other words, the protrusion 40a is also provided with a positioning post 42 that is staggered from the latch 41. The groove wall of the slot 30, specifically the inner groove wall, is provided with a positioning hole 32. The positioning hole 32 is staggered from the latch hole 31. The positioning post 42 engages with the positioning hole 32 to achieve positioning and improve the accuracy of the engagement between the plug 40 and the slot 30.

[0056] In one embodiment, the movable block 22 is provided with a slider 50 and an elastic reset member 60. The slider 50 can slide in the movable block 22 in a second direction, that is, in the front-back direction. The elastic reset member 60 can extend and retract in the second direction, that is, in the front-back direction. The two ends of the slider 50 in the second direction are a pressing end and a reset end, respectively. The pressing end is connected to a button 70 that extends out of the movable block 22. The reset end is connected to the inner wall of the movable block 22 through the elastic reset member 60. The movable block 22 is provided with a sliding hole 229 at the position corresponding to the buckle 41. One end of the buckle 41 passes through the sliding hole 229 to extend into the movable block 22 and connect with the slider 50. The other end of the buckle 41 has a hook 411 that bends toward the button 70. The hook 411 is used to hook onto the wall of the buckle hole 31 so that the buckle 41 is engaged with the buckle hole 31.

[0057] As shown in Figures 1 and 3 to 6, the following explanation will use the button 70 located at the front end of the right-side movable block 22 as an example. When it is necessary to detach the monocular observation component 10 from the right-side movable block 22, press the button 70 backward to push the slider 50 to slide backward relative to the movable block 22, thereby causing the latch 41 to slide backward, causing its hook 411 to disengage from the wall of the locking hole 31, thus releasing the latch 41 from the locking hole 31, thereby achieving the detachment of the monocular observation component 10 from the movable block 22. Furthermore, when the slider 50 slides backward relative to the movable block 22, the elastic reset member 60 is deformed under pressure. When the latch 41 disengages from the locking hole 31, the elastic reset member 60 pushes the slider 50 forward under the action of elastic restoring force, thereby causing the latch 41 to slide forward and reset. This structure is reasonably and ingeniously designed and easy to operate. In one embodiment, the elastic reset member 60 may be, but is not limited to, a compression spring.

[0058] To improve the assembly stability of the monocular observation component 10 and the connecting structure 20, each movable block 22 is provided with two latches 41 along the front-to-back direction, and a positioning post 42 is provided near each latch 41. Each latch 41 is also provided with a button 70, a slider 50, and an elastic reset member 60. The main body 11 of each monocular observation component 10 has a locking hole 31 at the position corresponding to the latch 41 and a positioning hole 32 at the position corresponding to the positioning post 42. The two buttons 70 on each movable block 22 are respectively located at the front and rear ends of the movable block 22. During use, by pushing the two buttons 70 with two fingers towards each other, the two latches 41 and the two locking holes 31 can be simultaneously released, which is easy to operate.

[0059] In another embodiment, the two monocular observation components 10 are communicatively connected via a connection structure 20. Understandably, the two monocular observation components 10 assembled together, communicatively connected via the connection structure 20, can achieve various functions, such as image fusion and picture-in-picture modes, or data transmission and data transfer functions, meeting diverse usage requirements.

[0060] Furthermore, each monocular observation component 10 has a first connector on the side of its main body 11 facing the corresponding connection structure 20; the connection structure 20 has a second connector at the position corresponding to each first connector, and the first connector and the corresponding second connector are plugged in and connected for communication.

[0061] As shown in Figures 1 to 6, each monocular observation component 10 has a first connector on its inner side of the main body 11, and each movable block 22 has a second connector on its second connecting side 222. The movable block 22 and the corresponding monocular observation component 10 can be assembled and disassembled through the insertion and engagement of the first and second connectors. Furthermore, both the first and second connectors are equipped with communication terminals 90, allowing for communication between two monocular observation components 10 through their insertion and engagement. This design is reasonable and ingenious.

[0062] In one embodiment, at least one monocular observation component 10 further includes an objective lens 13, with the eyepiece 12 and objective lens 13 respectively disposed at both ends of the main body 11 along a second direction. Specifically, at least one monocular observation component 10 includes a main body 11, an eyepiece 12, and an objective lens 13, with the main body 11 extending along a front-rear direction, and the eyepiece 12 and objective lens 13 respectively disposed at the front and rear ends of the main body 11. A connecting structure 20 is located between two monocular observation components 10, and the left and right sides of the connecting structure 20 are detachably connected to the two monocular observation components 10 respectively.

[0063] During use, when the two monocular observation components 10 are detached from the connecting structure 20, each monocular observation component 10, including a main body 11, an eyepiece 12, and an objective lens 13, can be used independently as a monocular handheld observation device. Therefore, this handheld observation device is flexible and convenient to use.

[0064] In the handheld observation device disclosed herein, one of the two monocular observation components 10 is one of a thermal imaging lens group, a visible light lens group, and a supplementary light lens group; the other monocular observation component 10 is the other of a thermal imaging lens group, a visible light lens group, and a supplementary light lens group.

[0065] In one embodiment, one of the two monocular observation components 10 is a thermal imaging lens group, and the other is a visible light lens group. The separation and combination of the two monocular observation components 10 can also achieve the separation and combination of the thermal imaging lens group and the visible light lens group. Both the thermal imaging lens group and the visible light lens group have objective lenses 13, allowing the separated thermal imaging lens group and the visible light lens group to be used individually as monocular handheld observation devices, while the combined thermal imaging lens group and the visible light lens group can be used as binocular handheld observation devices.

[0066] In another embodiment, one of the two monocular observation components 10 is a visible light lens group, and the other of the two monocular observation components 10 is a supplementary light lens group. In this combination, the visible light lens group has an objective lens 13, while the supplementary light lens group does not have an objective lens 13. Instead, an eyepiece 12 and a supplementary light lens are respectively provided at both ends of the main body 11 in the second direction (i.e., the front-back direction). The supplementary light lens group is not used as a monocular handheld observation device on its own, while the separated visible light lens group can be used as a monocular handheld observation device on its own.

[0067] Thus, by splitting and combining the two monocular observation components according to actual usage needs, it is possible to split and combine the thermal imaging lens group and the visible light lens group, as well as the visible light lens group and the supplementary lighting lens group. Therefore, this handheld observation device is flexible and versatile, thus meeting a variety of usage requirements.

[0068] Understandably, both eyepieces 12 have displays. Therefore, when the handheld observation device is used as a binocular handheld observation device, the observer observes one display screen through two displays. When the handheld observation device is used as a monocular handheld observation device, the observer observes one display screen through the corresponding display screen.

[0069] In one embodiment, an operation key assembly is provided on the side of the main body 11 facing a third direction. The operation key assembly includes a plurality of operation keys 80 spaced apart along a second direction, and the first, second, and third directions are perpendicular to each other. The third direction can be the up-down direction shown in Figure 1. An operation key assembly is provided on the upper side of each main body 11, and the operation key assembly avoids the connecting structure 20, resulting in a reasonable layout. The multiple operation keys 80 of the operation key assembly can realize different function adjustments, which will not be described in detail here.

[0070] The above descriptions are merely optional embodiments of this disclosure and are not intended to limit the scope of this disclosure. Any equivalent structural transformations made based on the technical concept of this disclosure and the contents of this specification and drawings, or direct / indirect applications in other related technical fields, are included within the protection scope of this disclosure.
