[0044] Currently, handheld observation devices include monocular and binocular devices. Monocular devices only allow for single-lens observation, not binocular observation, making them inconvenient to use. While binocular devices can achieve binocular observation, they typically come in an integrated design with the binoculars non-detachable, limiting their flexibility.

[0045] Moreover, binocular observation equipment usually has only one objective lens and a single image mode, which cannot meet various usage requirements.

[0046] The utility model provides a handheld observation device which solves the above problems.

[0047] like Figures 1 to 4 As shown, the handheld observation device includes a monocular observation component 10 and a connecting structure 20. There are two monocular observation components 10, which are arranged side by side along a first direction. Each monocular observation component 10 includes a main body 11 and an eyepiece 12. The main body 11 extends along a second direction, which is different from the first direction. The eyepiece 12 is located at one end of the main body 11 along the second direction. The connecting structure 20 is located between the two monocular observation components 10 and detachably connects the two monocular observation components 10, forming 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 interpupillary distance between the two eyepieces 12.

[0048] In one embodiment, the first direction is Figure 1 The left and right directions shown, the second direction is Figure 1 The handheld observation device features two monocular observation assemblies 10 arranged side by side in the left-right direction, facilitating binocular observation for the user, thus ergonomically designed. Each monocular observation assembly 10 includes a main body 11 extending in the front-to-back direction and an eyepiece 12 disposed at the front end of the main body 11.

[0049] During use of the handheld observation device of this embodiment, if the monocular observation assembly 10 is removed from the connecting structure 20, separating the two monocular observation assemblies 10, at least one of the monocular observation assemblies 10 can be used as a monocular handheld observation device. When the two monocular observation assemblies 10 are assembled together via the connecting structure 20, they can also be used as a binocular handheld observation device, providing flexibility and convenience. Furthermore, when the two monocular observation assemblies 10 are assembled together via the connecting structure 20, at least one of the monocular observation assemblies 10 can move relative to the connecting structure 20 in the first direction to adjust the interpupillary distance between the two eyepieces 12.

[0050] In an embodiment, the two monocular observation assemblies 10 are movable relative to the connecting structure 20 along the left-right direction, so that the two monocular observation assemblies 10 are closer to or farther away from each other along the left-right direction, thereby adjusting the interpupillary distance between the two eyepieces 12 to adapt to the use requirements of different interpupillary distances, flexible and convenient to use, and good in applicability.

[0051] In another embodiment, one of the monocular observation assemblies 10 is movable relative to the connecting structure 20 along the left-right direction, so that it is closer to or farther away from the other monocular observation assembly 10 along the left-right direction, thereby adjusting the interpupillary distance between the two eyepieces 12 to adapt to the use requirements of different interpupillary distances, flexible and convenient to use, and good in applicability.

[0052] In an embodiment, the connecting structure 20 comprises a rotating shaft 21 and two movable blocks 22, the rotating shaft 21 is arranged to extend along the second direction, and the two movable blocks 22 are arranged opposite to each other along the first direction and are respectively detachably connected with the two monocular observation assemblies 10; at least one of the movable blocks 22 is rotationally connected with the rotating shaft 21, so that the corresponding monocular observation assembly 10 can rotate around the rotating shaft 21 to adjust the interpupillary distance between the two eyepieces 12.

[0053] As shown in Figure 1 , Figure 3 and Figure 4 , the rotating shaft 21 is arranged to extend along the front-rear direction, and the two movable blocks 22 are arranged opposite to each other along the left-right direction, and the movable block 22 located on the left side is detachably connected with the monocular observation assembly 10 arranged on the same side thereof, and the movable block 22 located on the right side is detachably connected with the monocular observation assembly 10 arranged on the same side thereof, facilitating disassembly and assembly. In order to adapt to the interpupillary distances of different users, at least one of the movable blocks 22 is rotationally connected with the rotating shaft 21, so that the corresponding monocular observation assembly 10 can rotate clockwise or counterclockwise around the rotating shaft 21 to adjust the interpupillary distance between the two eyepieces 12.

[0054] In an embodiment, the movable block 22 has a first connecting side 221 and a second connecting side 222 on both sides along the first direction, the first connecting side 221 of at least one of the movable blocks 22 is rotationally sleeved on the rotating shaft 21, and the second connecting side 222 is detachably connected with the corresponding monocular observation assembly 10, thereby realizing the disassembly and assembly of the movable block 22 and the monocular observation assembly 10 arranged on the same side.

[0055] The two ends of the rotating shaft 21 in the second direction, i.e. the front and back ends of the rotating shaft 21, are respectively provided with two limiting members 211, and the movable block 22 is located between the two limiting members 211, and the two limiting members 211 abut against the two ends of the movable block 22 in the second direction, so that the movable block 22 is limited in the front-back direction through the cooperation of the two limiting members 211, thereby improving the assembly stability of the movable block 22 and the rotating shaft 21. Moreover, in the process of rotating the monocular observation assembly 10 around the rotating shaft 21 by the user, since each limiting member 211 abuts against the movable block 22 and the limiting member 211 and the movable block 22 are in frictional cooperation, the user needs to exert a certain torque to rotate the monocular observation assembly 10, which can improve the use feeling and provide a certain locking force by using the frictional force between the limiting member 211 and the movable block 22 after the monocular observation assembly 10 is rotated to a suitable angle, so that the monocular observation assembly 10 can be kept at a suitable angle, and the interpupillary distance between the two ocular lenses 12 will not change unintentionally after being adjusted to the right position.

[0056] Further, the first connecting side 221 of one movable block 22 is provided with a sleeve 223, and the sleeve 223 is rotatably sleeved on the rotating shaft 21; the first connecting side 221 of the other movable block 22 is provided with two sleeve rings 224 at the two ends in the second direction, the sleeve 223 abuts against the two sleeve rings 224, and the two sleeve rings 224 are rotatably sleeved on the rotating shaft 21, and the two sleeve rings 224 are located between the two limiting members 211 and abut against the two limiting members 211.

[0057] Specifically, as shown in Figures 1 to 4 the first connecting side 221 of the movable block 22 on the left side is provided with a sleeve 223, and the sleeve 223 is rotatably sleeved on the rotating shaft 21 to realize the rotation of the movable block 22 on the left side around the rotating shaft 21. The first connecting side 221 of the movable block 22 on the right side is provided with two sleeve rings 224 at the two ends in the second direction, i.e. the front end and the back end, and the two sleeve rings 224 are rotatably sleeved on the rotating shaft 21 to realize the rotation of the movable block 22 on the right side around the rotating shaft 21. In this way, the adjustment of the interpupillary distance between the two ocular lenses 12 can be realized by rotating any monocular observation assembly 10 or simultaneously rotating the two monocular observation assemblies 10, and the use is flexible and convenient. The front and back ends of the sleeve 223 abut against the two sleeve rings 224, so that the front and back ends of the sleeve 223 can be in frictional cooperation with the two sleeve rings 224, further increasing the torque required by the user to rotate the monocular observation assembly 10, thereby further improving the use feeling and ensuring that the interpupillary distance between the two ocular lenses 12 remains stable after being adjusted to the right position and does not change unintentionally. In an embodiment, the sleeve 223 and the rotating shaft 21 are both provided with a threading hole 212 for facilitating the threading of a wire harness, which is a reasonable design.

[0058] Further, the two limit members 211 are a limit plate 211a and a limit nut 211b, the two ends of the rotating shaft 21 along the second direction, i.e. the front end and the rear end, are a first end and a second end, and the two sleeves 224 are a first sleeve 224 and a second sleeve 224; the limit plate 211a is fixed to the first end and abuts against the first sleeve 224, and the second end of the rotating shaft 21 is provided with a threaded segment 213, the limit nut 211b is sleeved on the second end and is threadedly connected with the threaded segment 213 and abuts against the second sleeve 224.

[0059] The limit plate 211a is fixed to the front end of the rotating shaft 21 and abuts against the front end face of the first sleeve 224, and the limit nut 211b is threadedly connected with the threaded segment 213 of the rear end of the rotating shaft 21 and abuts against the rear end face of the second sleeve 224, so that the two movable blocks 22 can be abutted from the front-rear direction by screwing the limit nut 211b in cooperation with the limit plate 211a, which is not only convenient and flexible in operation, but also further increases the torque required to be applied by the user when rotating the monocular observation assembly 10, thereby providing a better use feeling and improving the reliability of the interpupillary distance between the two ocular lenses 12 after being adjusted in place.

[0060] In an embodiment, a first friction pad 225 is arranged between the first sleeve 224 and the sleeve 223; a second friction pad 226 is arranged between the second sleeve 224 and the sleeve 223; and a friction assembly is arranged between the limit nut 211b and the second sleeve 224, which includes two spring sheets 227 and a pad 228 arranged between the two spring sheets 227.

[0061] The first friction pad 225 and the second friction pad 226 are arranged to respectively increase the friction between the front and rear ends of the sleeve 223 and the corresponding sleeve 224, and further improve the use feeling. Moreover, the friction assembly is arranged between the limit nut 211b and the second sleeve 224, and the friction assembly includes two spring sheets 227 and a pad 228 arranged between the two spring sheets 227, the spring sheets 227 can abut against the second sleeve 224 by the elastic force thereof, and the front and rear sides of the spring sheets 227 are abutted against the second sleeve 224 and the limit nut 211b by the two pads 228, thereby increasing the friction. The deformation degree of the spring sheets 227 is adjusted by screwing the nut, so as to adjust the elastic force of the spring sheets 227, and further adjust the torque required to be applied by the user when rotating the monocular observation assembly 10 by the change of the elastic force, so as to adjust the use feeling and the locking force of the movable block 22 after being rotated in place. In an embodiment, the spring sheets 227 can be disc springs in the prior art.

[0062] In an embodiment, each main body 11 is provided with a first plug at one side of the connecting structure 20; the connecting structure 20 is provided with a second plug at a position corresponding to each first plug, and the first plug is plugged with the corresponding second plug.

[0065] In an embodiment, the connecting structure 20 has a contact surface 2221 which matches the shape of the outer wall of the main body 11 and is in contact with the outer wall of the main body 11, and the plug 40 is a protrusion 40a which protrudes from the contact surface 2221 in a direction away from the contact surface 2221.

[0066] Specifically, the main body 11 of each monocular observation assembly 10 is cylindrical, which is a single lens group. 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 which is an arc surface matching the shape of the outer wall of the main body 11, which is reasonably designed and convenient for assembling with the main body 11. The plug 40 is located on the contact surface 2221 and protrudes outward from the contact surface 2221 to form a protrusion 40a, so as to be plugged with the slot 30.

[0067] Further, the protrusion 40a is provided with a buckle 41, and the slot wall of the slot 30 is provided with a clamping hole 31 which clamps the buckle 41. The slot opening of the slot 30 is outward, and the slot wall of the slot 30, specifically the bottom slot wall opposite to the slot opening, is provided with the clamping hole 31. When the plug 40 is plugged with the slot 30, the buckle 41 is clamped with the clamping hole 31, which improves the assembly stability.

[0068] The protrusion 40a is also provided with a positioning column 42 which is spaced apart from the buckle 41, and the slot wall of the slot 30 is also provided with a positioning hole 32 which is plugged with the positioning column 42. The protrusion 40a is also provided with the positioning column 42 which is distributed away from the buckle 41, and the slot wall of the slot 30, specifically the bottom slot wall, is provided with the positioning hole 32. The positioning hole 32 is distributed away from the clamping hole 31, and the positioning column 42 is plugged with the positioning hole 32 to realize positioning and improve the accuracy of plugging of the plug 40 with the slot 30.

[0069] ​In an embodiment, the movable block 22 is provided with a sliding block 50 and an elastic reset member 60, the sliding block 50 is capable of sliding in the second direction, i.e. the front-back direction, in the movable block 22, the elastic reset member 60 is capable of stretching and contracting in the second direction, i.e. the elastic reset member 60 is capable of stretching and contracting in the front-back direction; the two ends of the sliding block 50 in the second direction are a pressing end and a reset end respectively, the pressing end is connected with a button 70 which is out of the movable block 22, the reset end is connected with 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 corresponding to the position of the buckle 41, one end of the buckle 41 passes through the sliding hole 229 to extend into the movable block 22 and is connected with the sliding block 50, the other end of the buckle 41 is provided with a bent hook 411 which is bent towards the button 70, the bent hook 411 is used for hooking on the hole wall of the clamping hole 31 to make the buckle 41 clamped with the clamping hole 31.

[0070] As shown in Figure 1 , Figures 3 to 6 Taking the button 70 provided at the front end of the right movable block 22 as an example, when it is needed to disassemble the monocular observation assembly 10 from the right movable block 22, the button 70 is pressed backward to push the sliding block 50 to slide backward relative to the movable block 22, and then drive the buckle 41 to slide backward, so that the bent hook 411 of the buckle 41 is separated from the hole wall of the clamping hole 31, thereby the buckle 41 is disengaged from the clamping hole 31, and then the monocular observation assembly 10 is disengaged from the movable block 22. When the sliding block 50 slides backward relative to the movable block 22, the elastic reset member 60 is deformed under pressure. When the buckle 41 is disengaged from the clamping hole 31, the elastic reset member 60 pushes the sliding block 50 forward under the action of elastic restoring force to drive the buckle 41 to slide forward to reset, which is reasonable and ingenious in structure design and convenient to operate.

[0072] In another embodiment, two monocular observation assemblies 10 are communicatively connected via a connection structure 20. It is understood that the two assembled monocular observation assemblies 10 are communicatively connected via the connection structure 20 to achieve multiple functions, such as realizing multiple image modes such as picture fusion and picture-in-picture, or realizing data transmission and data transfer, etc., to meet various usage requirements.

A connecting structure 20 is positioned between the two monocular observation assemblies 10, and the left and right sides of the connecting structure 20 are detachably connected to the two monocular observation assemblies 10.

[0076] During use of the handheld observation device, if the monocular observation component 10 is removed from the connecting structure 20, the two monocular observation components 10 are separated. Since each monocular observation component 10 includes a main body 11, an eyepiece 12 and an objective lens 13, the two separated monocular observation components 10 can be used separately as monocular handheld observation devices, which is flexible and convenient to use.

[0077] In the handheld observation device of the present invention, one monocular observation component 10 is one of a thermal imaging lens group, a visible light lens group, and a fill light lens group; the other monocular observation component 10 is the other one of the thermal imaging lens group, the visible light lens group, and the fill light lens group.

[0078] In an embodiment, one monocular observation assembly 10 is a thermal imaging lens group, and the other monocular observation assembly is a visible light lens group, and the splitting and combination between the thermal imaging lens group and the visible light lens group is realized by splitting and combination between the two monocular observation assemblies 10. The thermal imaging lens group and the visible light lens group both have objective lenses 13, so that the split thermal imaging lens group and the visible light lens group can be used as monocular handheld observation devices, and the combined thermal imaging lens group and the visible light lens group can be used as binocular handheld observation devices.

[0079] In another embodiment, one monocular observation assembly 10 is a visible light lens group, and the other monocular observation assembly is an auxiliary light lens group, and in this combination mode, the visible light lens group has an objective lens 13, and the auxiliary light lens group does not have an objective lens 13, but has an eyepiece 12 and an auxiliary light lens at the two ends of the main body 11 in the second direction, i.e. the front-back direction, and the split visible light lens group can be used as a monocular handheld observation device.

[0080] In this way, according to actual use requirements, the splitting and combination between the thermal imaging lens group and the visible light lens group, and the splitting and combination between the light lens group and the auxiliary light lens group are realized by splitting and combination between the two monocular observation assemblies, which is flexible and variable, and thus meets various use requirements.

[0081] It can be understood that the two eyepieces 12 both have displays, and when used as binocular handheld observation devices, the observer observes a display screen through the two displays. When used as monocular handheld observation devices, the observer observes a display screen through the corresponding display.

[0082] In an embodiment, the side of the main body 11 facing the third direction is provided with an operation key assembly, and the operation key assembly includes a plurality of operation keys 80 arranged at intervals along the first direction, and the first direction, the second direction and the third direction are perpendicular to each other. The third direction can be the upward-downward direction as shown in the drawings, and the upper side of each main body 11 is provided with an operation key assembly, and the operation key assembly avoids the connecting structure 20 and has a reasonable layout. The plurality of operation keys 80 of the operation key assembly can realize different function adjustments, and the plurality of operation keys 80 realizing different function adjustments adopt prior art, which will not be described here.
