Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical imaging devices, in particular to a binocular hand-held telescope. BACKGROUND

[0002] In the existing hand-held telescope, when a pair of lenses are the same optical lenses, a scheme of simultaneously adjusting the focus of the two lenses by a single focus wheel is mostly adopted. However, when a pair of lenses are optical lenses with different focus parameters, such as a multi-light binocular thermal imaging device including a visible light lens and an infrared light lens, the two lenses cannot be simultaneously adjusted in focus due to different focal lengths or different adjustment strokes of the focal lengths, and therefore a focus adjusting device is usually provided for only one lens, which results in poor imaging effect.

[0004] In an embodiment of the present application, a binocular hand-held telescope is provided, which comprises:

[0005] a first lens barrel and a second lens barrel, the first lens barrel and the second lens barrel are arranged side by side, a first optical imaging system is arranged in the first lens barrel, and a second optical imaging system is arranged in the second lens barrel, the first optical imaging system and the second optical imaging system have different focus parameters;

[0006] a hand-held assembly connected between the first lens barrel and the second lens barrel;

[0007] wherein the hand-held assembly comprises a focus adjusting assembly, the focus adjusting assembly independently adjusts the focal lengths of the first optical imaging system and the second optical imaging system.

[0011] In an embodiment, the focus adjusting assembly comprises a first focus adjusting roller, the first focus adjusting roller selectively connects one of the first transmission mechanism and the second transmission mechanism to respectively adjust the focal lengths of the first optical imaging system and the second optical imaging system.

[0012] In one embodiment, the first focusing roller is axially mounted on the focusing shaft, and the first focusing roller synchronously drives the focusing shaft to rotate axially.

[0013] The focusing shaft selectively connects one of the first transmission mechanism and the second transmission mechanism.

[0014] In one embodiment, the handheld assembly comprises:

[0015] A shift switch having a first gear connected between the focusing shaft and the first transmission mechanism, and a second gear connected between the focusing shaft and the second transmission mechanism.

[0016] In one embodiment, the handheld assembly comprises:

[0017] A first shift switch to establish or break the connection between the focusing shaft and the first transmission mechanism; and

[0018] A second shift switch to establish or break the connection between the focusing shaft and the second transmission mechanism.

[0019] In one embodiment, the focusing shaft comprises a first focusing shaft connected with the first transmission mechanism, and a second focusing shaft connected with the second transmission mechanism, the first focusing shaft and the second focusing shaft are coaxially spaced apart;

[0020] The first focusing roller is movable along the axial direction of the focusing shaft, the first focusing roller has a first focusing position engaged with the first focusing shaft to synchronously drive the first focusing shaft to rotate axially, and a second focusing position engaged with the second focusing shaft to synchronously drive the second focusing shaft to rotate axially.

[0040] Now each example embodiment will be described more completely with reference to the accompanying drawings.

[0041] First embodiment

[0042] As Figure 1 shown, one embodiment of the present application provides a binocular handheld telescope, comprising:

[0043] A first lens barrel 10 and a second lens barrel 20 are arranged side by side, wherein the first lens barrel 10 is provided with a first optical imaging system, the second lens barrel 20 is provided with a second optical imaging system, and the focusing parameters of the first optical imaging system and the second optical imaging system are different;

[0044] A handheld assembly 30 is connected between the first lens barrel 10 and the second lens barrel 20;

[0045] Wherein, the handheld assembly 30 comprises a focusing assembly 40, and the focusing assembly 40 adjusts the focal length of the first optical imaging system and the second optical imaging system independently.

[0046] As Figure 1The telescope of the present example adopts a common double-barrel structure, in which the first barrel 10 and the second barrel 20 are arranged side by side. The first optical imaging system can for example include a first objective lens assembly 11 arranged at the first end of the first barrel 10 and a first eyepiece assembly arranged at the second end of the first barrel 10, and the second optical imaging system can include a second objective lens assembly 21 arranged at the first end of the second barrel 20 and a second eyepiece assembly arranged at the second end of the second barrel 20. The objective lens assemblies are arranged at the distal ends (first ends) of the first barrel 10 and the second barrel 20, i.e. the side away from the operator, and the eyepiece assemblies are arranged at the proximal ends (second ends) of the first barrel 10 and the second barrel 20, i.e. the side through which the operator observes. The hand-held assembly 30 connects the first barrel 10 and the second barrel 20 into a whole and provides a part for the operator to hold. In addition to the functions of connection and holding, the hand-held assembly 30 is also used to arrange an operation panel, such as a button 32. The hand-held assembly 30 is adjacent to the side of the eyepiece assembly, which is convenient for the operator to operate.

[0047] The hand-held assembly 30 includes a focusing assembly 40 for adjusting the focal length of the objective lens assemblies. The focusing assembly 40 can be realized in the form of a focusing roller. The number of the focusing rollers can be one or two, which is less than or equal to the number of the objective lens assemblies. Whether the number of the focusing rollers corresponds to the number of the objective lens assemblies or not, the adjustment of the focal length of the objective lens assemblies by the focusing rollers is one-to-one. That is, one focusing roller adjusts the focal length of only one objective lens assembly at the same time.

[0048] When the number of the focusing rollers is one, the focusing roller can be used to independently adjust the focal length of the two objective lens assemblies. When the number of the focusing assembly 40 is two, the two focusing rollers are used to respectively adjust the focal length of the two objective lens assemblies. The present scheme can realize the focal length adjustment of the optical imaging systems with different focusing parameters by a single focusing assembly, or can realize the focusing of the two optical imaging systems by two rollers respectively, or can realize the focal length adjustment of the optical imaging systems with different focusing parameters by a number of focusing devices less than or equal to the number of the lenses, so that the optical systems in different barrels can be independently focused.

[0049] In the present example, the focusing parameters of the first optical imaging system and the second optical imaging system are different. The focusing parameters can include but are not limited to the photosensitive wavelength range of the objective lens assembly, the focal length position, the focal length adjustment stroke, etc. Specifically, for example, the first objective lens assembly 11 is an infrared lens, and the second objective lens assembly 21 is a visible light lens.

[0050] Obviously, for optical lenses with different photosensitive wavelength ranges, the focal length cannot be adjusted at the same time, so the focal length of the optical lenses needs to be adjusted respectively.

[0051] Specifically, the handheld telescope of the present embodiment comprises:

[0052] a first transmission mechanism 41 connected to the first objective lens assembly 11, the focusing assembly 40 adjusting the focal length of the first objective lens assembly 11 via the first transmission mechanism 41; and

[0053] a second transmission mechanism 42 connected to the second objective lens assembly 21, the focusing assembly 40 adjusting the focal length of the second objective lens assembly 21 via the second transmission mechanism 42.

[0054] The focusing assembly 40 is arranged at the handheld assembly 30, which is adjacent to the proximal ends of the first lens barrel 10 and the second lens barrel 20, while the objective lens assemblies are arranged at the distal ends of the first lens barrel 10 and the second lens barrel 20. Therefore, the handheld telescope of the present embodiment further comprises transmission mechanisms connected between the focusing assembly 40 and the objective lens assemblies. Based on the principle of focusing on the objective lens assemblies respectively, the number of transmission mechanisms in the present embodiment is one-to-one corresponding to the number of objective lens assemblies. Specifically, the transmission mechanisms comprise a first transmission mechanism 41 connected to the first objective lens assembly 11 and a second transmission mechanism 42 connected to the second objective lens assembly 21, the focusing assembly 40 adjusting the focal length of the first objective lens assembly 11 via the first transmission mechanism 41 and adjusting the focal length of the second objective lens assembly 21 via the second transmission mechanism 42.

[0055] In the present example, the focusing assembly 40 comprises a first focusing roller 401, which is selectively connected to one of the first transmission mechanism 41 and the second transmission mechanism 42 to adjust the focal length of the first objective lens assembly 11 and the second objective lens assembly 21 respectively.

[0056] That is, the first focusing roller 401 can only be connected to one of the first transmission mechanism 41 and the second transmission mechanism 42 at any time, so as to adjust one of the first objective lens assembly 11 and the second objective lens assembly 21 at any time.

[0057] Specifically, the first focusing roller 401 is axially arranged on the focusing shaft 44, and the first focusing roller 401 synchronously drives the focusing shaft 44 to rotate axially.

[0058] The focusing shaft 44 is selectively connected to one of the first transmission mechanism 41 and the second transmission mechanism 42.

[0059] In the present example, the first focusing roller 401 drives the first transmission mechanism 41 or the second transmission mechanism 42 through the focusing shaft 44, and the first focusing roller 401 rotates synchronously with the focusing shaft 44, rather than rotating around the focusing shaft 44. For example, the first focusing roller 401 is fixed on the focusing shaft 44, and the first focusing roller 401 is coaxially arranged with the focusing shaft 44.

[0060] In one specific example, the handheld assembly 30 comprises:

[0061] a shift switch 31 having a first gear connected between the focusing shaft 44 and the first transmission mechanism 42, and a second gear connected between the focusing shaft 44 and the second transmission mechanism 42.

[0062] The shift switch 31 serves as a connection bridge between the focusing shaft 44 and the two transmission mechanisms, and realizes the selective connection of the focusing shaft 44 with the first transmission mechanism 41 and the second transmission mechanism 42. Specifically, the shift switch 31 can have two gears. When the shift switch 31 is in the first gear, the focusing shaft 44 is connected to the first transmission mechanism 42 via the shift switch 31. When the first focusing roller 401 rotates in response to the external force of the operator, the focusing shaft 44 is driven to rotate synchronously to adjust the focal length of the first objective assembly 11 via the first transmission mechanism 42. When the shift switch 31 is in the second gear, the focusing shaft 44 is connected to the second transmission mechanism 42 via the shift switch 31. When the first focusing roller 401 rotates in response to the external force of the operator, the focusing shaft 44 is driven to rotate synchronously to adjust the focal length of the second objective assembly 21 via the second transmission mechanism 42.

[0063] Optionally, in one specific example, the handheld assembly 30 comprises:

[0064] a first shift switch for establishing or breaking the connection between the focusing shaft 44 and the first transmission mechanism 42; and

[0065] a second shift switch for establishing or breaking the connection between the focusing shaft 44 and the second transmission mechanism 42.

[0066] In the present example, two shift switches are included, each of which adjusts the connection relationship between the focusing shaft 44 and one of the transmission mechanisms. Specifically, the first shift switch is located between the focusing shaft 44 and the first transmission mechanism 42. The first shift switch has a first position for establishing the connection between the focusing shaft 44 and the first transmission mechanism 42, and a second position for breaking the connection between the focusing shaft 44 and the first transmission mechanism 42. Similarly, the second shift switch is located between the focusing shaft 44 and the second transmission mechanism 42. The second shift switch has a first position for establishing the connection between the focusing shaft 44 and the second transmission mechanism 42, and a second position for breaking the connection between the focusing shaft 44 and the second transmission mechanism 42.

[0067] The first shift switch and the second shift switch are located at opposite positions to realize the selective connection of the focusing shaft 44 with the first transmission mechanism 41 and the second transmission mechanism 42. For example, when the first shift switch is in the first position, the second shift switch is in the second position. Alternatively, when the first shift switch is in the second position, the second shift switch is in the first position.

[0068] The embodiment of the present application provides a binocular hand-held telescope, which can realize focal length adjustment of multiple optical imaging systems with different focusing parameters in different barrels through a focusing assembly. For the optical imaging systems with different focusing parameters, the focal lengths of the optical lenses are adjusted respectively. Based on the principle of adjusting the focusing actions of the objective lens assemblies respectively, the number of the transmission mechanisms in the embodiment is one-to-one corresponding to the number of the objective lens assemblies. Specifically, the first transmission mechanism 41 connected to the first objective lens assembly 11 and the second transmission mechanism 42 connected to the second objective lens assembly 21 are included, the first focusing roller 401 adjusts the focal length of the first objective lens assembly 11 through the first transmission mechanism 41 and adjusts the focal length of the second objective lens assembly 21 through the second transmission mechanism 42.

[0069] Second embodiment

[0070] As shown in Figure 2a and Figure 2b The embodiment of the present application provides a binocular hand-held telescope, which comprises:

[0071] The first barrel 10 and the second barrel 20 are arranged side by side, wherein the first barrel 10 is internally provided with a first optical imaging system, the second barrel 20 is internally provided with a second optical imaging system, and the focusing parameters of the first optical imaging system and the second optical imaging system are different.

[0072] The hand-held assembly 30 is connected between the first barrel 10 and the second barrel 20.

[0073] The hand-held assembly 30 comprises a focusing assembly 40, and the focusing assembly 40 independently adjusts the focal lengths of the first optical imaging system and the second optical imaging system.

[0074] The first optical imaging system can comprise, for example, a first objective lens assembly 11 arranged at the first end of the first barrel 10 and a first eyepiece assembly arranged at the second end of the first barrel 10, and the second optical imaging system can comprise a second objective lens assembly 21 arranged at the first end of the second barrel 20 and a second eyepiece assembly arranged at the second end of the second barrel 20. The objective lens assemblies are arranged at the far ends (the first ends) of the first barrel 10 and the second barrel 20, i.e. the sides far away from the observation of the operator, and the eyepiece assemblies are arranged at the near ends (the second ends) of the first barrel 10 and the second barrel 20, i.e. the sides through which the operator observes. The hand-held assembly 30 connects the first barrel 10 and the second barrel 20 into a whole and provides a hand-holding position for the operator. In addition to the functions of connection and hand-holding, the hand-held assembly 30 is also used for arranging an operation panel, such as a key 32. The hand-held assembly 30 is adjacent to the side of the eyepiece assembly, which is convenient for the operator.

[0075] In the present example, the focusing parameters of the first optical imaging system and the second optical imaging system are different. The focusing parameters can include, but are not limited to, the photosensitive wavelength range of the objective assembly, the focal length position, the focal length adjustment stroke, etc. Specifically, for example, the first objective assembly 11 is an infrared lens, and the second objective assembly 21 is a visible light lens.

[0076] Specifically, comprising:

[0077] The first transmission mechanism 41 is connected to the first objective assembly 11, and the focusing assembly 40 adjusts the focal length of the first objective assembly 11 through the first transmission mechanism 41; and

[0078] The second transmission mechanism 42 is connected to the second objective assembly 21, and the focusing assembly 40 adjusts the focal length of the second objective assembly 21 through the second transmission mechanism 42.

[0079] In the present example, the focusing assembly 40 includes a first focusing roller 401, which is selectively connected to one of the first transmission mechanism 41 and the second transmission mechanism 42 to adjust the focal length of the first objective assembly 11 and the second objective assembly 21, respectively.

[0080] Specifically, the first focusing roller 401 is axially arranged on the focusing shaft 44, and the first focusing roller 401 synchronously drives the focusing shaft 44 to rotate axially;

[0081] The focusing shaft 44 is selectively connected to one of the first transmission mechanism 41 and the second transmission mechanism 42.

[0082] The focusing shaft 44 includes a first focusing shaft 441 connected to the first transmission mechanism 41 and a second focusing shaft 442 connected to the second transmission mechanism 42, and the first focusing shaft 441 and the second focusing shaft 442 are coaxially and spaced apart;

[0083] The first focusing roller 401 is movable along the axial direction of the focusing shaft 44, and the first focusing roller 401 has a first focusing position as shown in Figure 2a engaged with the first focusing shaft 441 to synchronously drive the first focusing shaft 441 to rotate axially, and a second focusing position as shown in Figure 2b engaged with the second focusing shaft 442 to synchronously drive the second focusing shaft 442 to rotate axially.

[0084] The focusing shaft 44 includes a first focusing shaft 441 and a second focusing shaft 442 spaced apart. The first focusing shaft 441 and the second focusing shaft 442 are arranged along the same axial direction. The first focusing roller 401 is movable along the axial direction of the focusing shaft 44, but not along the physical focusing shaft 44. For example, the first focusing roller 401 can be confined within an adjustment frame. In the radial direction, the first focusing roller 401 is confined within the adjustment frame and has no degree of freedom of movement. However, in the axial direction, the first focusing roller 401 has a degree of freedom of movement. The first focusing shaft 441 and the second focusing shaft 442 are located at opposite ends in the axial direction. When the first focusing roller 401 moves along the axial direction of the focusing shaft 44, it can engage with the first focusing shaft 441 and the second focusing shaft 442 at opposite ends in the axial direction of the adjustment frame, respectively, to adjust the focal length of the first objective lens assembly 11 and the second objective lens assembly 21 via the first transmission mechanism 41 and the second transmission mechanism 42, respectively.

[0085] This application provides a binocular handheld telescope that allows for focal length adjustment of multiple optical imaging systems with different focusing parameters located within different lens barrels via a focusing assembly. For optical imaging systems with different focusing parameters, the focal length is adjusted separately for each optical lens. Based on the principle of focusing separately for each objective lens assembly, the transmission mechanism in this embodiment corresponds one-to-one with the number of objective lens assemblies. Specifically, it includes a first transmission mechanism 41 connected to the first objective lens assembly 11 and a second transmission mechanism 42 connected to the second objective lens assembly 21. The focusing assembly 40 adjusts the focal length of the first objective lens assembly 11 via the first transmission mechanism 41 and adjusts the focal length of the second objective lens assembly 21 via the second transmission mechanism 42.

[0086] The first focusing roller 401 is movable along the axial direction of the focusing shaft 44. The focusing shaft 44 includes a first focusing shaft 441 connected to the first transmission mechanism 41 and a second focusing shaft 442 connected to the second transmission mechanism 42. The first focusing shaft 441 and the second focusing shaft 442 are coaxially spaced apart. The first focusing roller 401 is movable along the axial direction of the focusing shaft 44 and has a first focusing position that engages with the first focusing shaft 441 to synchronously drive the first focusing shaft 441 to rotate axially, and a second focusing position that engages with the second focusing shaft 442 to synchronously drive the second focusing shaft 442 to rotate axially. The focal lengths of the first objective lens assembly 11 and the second objective lens assembly 21 are adjusted via the first transmission mechanism 41 and the second transmission mechanism 42, respectively.

[0087] Third Embodiment

[0088] like Figure 3 As shown, one embodiment of this application provides a binocular handheld telescope, comprising:

[0089] a first lens barrel 10 and a second lens barrel 20, the first lens barrel 10 and the second lens barrel 20 are arranged side by side, wherein the first lens barrel 10 is internally provided with a first optical imaging system, the second lens barrel 20 is internally provided with a second optical imaging system, and the focusing parameters of the first optical imaging system and the second optical imaging system are different;

[0090] a hand-held assembly 30 connected between the first lens barrel 10 and the second lens barrel 20;

[0091] wherein the hand-held assembly 30 comprises a focusing assembly 40, and the focusing assembly 40 independently adjusts the focal lengths of the first optical imaging system and the second optical imaging system.

[0092] In the present example, the first optical imaging system may, for example, comprise a first objective lens assembly 11 arranged at a first end of the first lens barrel 10 and a first eyepiece assembly arranged at a second end of the first lens barrel 10, and the second optical imaging system may, for example, comprise a second objective lens assembly 21 arranged at a first end of the second lens barrel 20 and a second eyepiece assembly arranged at a second end of the second lens barrel 20. The objective lens assembly is arranged at the distal end (first end) of the first lens barrel 10 and the second lens barrel 20, i.e. the side away from the operator's observation, and the eyepiece assembly is arranged at the proximal end (second end) of the first lens barrel 10 and the second lens barrel 20, i.e. the side through which the operator observes. The hand-held assembly 30 connects the first lens barrel 10 and the second lens barrel 20 into one body and provides a part for the operator to hold. In addition to providing the functions of connection and holding, the hand-held assembly 30 is also used to arrange an operation panel, such as a button 32, etc. The hand-held assembly 30 is adjacent to the side of the eyepiece assembly, which is convenient for the operator to operate.

[0093] In the present example, the focusing parameters of the first optical imaging system and the second optical imaging system are different. The focusing parameters may, for example, include but are not limited to the photosensitive wavelength range of the objective lens assembly, the focal length position, the focal length adjustment stroke, etc. Specifically, for example, the first objective lens assembly 11 is an infrared lens, and the second objective lens assembly 21 is a visible light lens.

[0094] Specifically, the present application comprises:

[0095] a first transmission mechanism 41 connected to the first objective lens assembly 11, and the focusing assembly 40 adjusts the focal length of the first objective lens assembly 11 through the first transmission mechanism 41; and

[0096] a second transmission mechanism 42 connected to the second objective lens assembly 21, and the focusing assembly 40 adjusts the focal length of the second objective lens assembly 21 through the second transmission mechanism 42.

[0097] In the present example, the focusing assembly 40 comprises a first focusing assembly 401 and a second focusing assembly 402;

[0098] The first focusing roller 401 adjusts the focal length of the first objective assembly 11 via the first transmission mechanism 41, and the second focusing roller 402 adjusts the focal length of the second objective assembly 21 via the second transmission mechanism 42.

[0099] Specifically, the focusing system comprises a first focusing shaft 441 connected to the first transmission mechanism 41 and a second focusing shaft 442 connected to the second transmission mechanism 42, and the first focusing shaft 441 and the second focusing shaft 442 are coaxially and spaced apart.

[0100] The first focusing roller 401 is engaged with the first focusing shaft 441 to drive the first focusing shaft 441 to rotate axially synchronously, and the second focusing roller 402 is engaged with the second focusing shaft 442 to drive the second focusing shaft 442 to rotate axially synchronously.

[0101] In the present example, the number of focusing rollers corresponds to the number of objective assemblies. The focal length adjustment of the first objective assembly 11 by the first focusing roller 401 and the focal length adjustment of the second objective assembly 21 by the second focusing roller 402 are independent of each other, the first focusing shaft and the second focusing shaft are spaced apart, and the first transmission mechanism and the second transmission mechanism are also independent of each other. Therefore, the focal length adjustment of the first objective assembly 11 and the second objective assembly 21 can be performed simultaneously, but the optical systems in different barrels are adjusted independently.

[0103] In one example, an embodiment of the present application provides a binocular handheld telescope, comprising:

[0104] A first barrel 10 and a second barrel 20, the first barrel 10 and the second barrel 20 are arranged side by side;

[0105] An objective assembly, the objective assembly comprises a first objective assembly 11 arranged at the first end of the first barrel 10 and a second objective assembly 21 arranged at the first end of the second barrel 20;

[0106] An eyepiece assembly, the eyepiece assembly comprises a first eyepiece assembly arranged at the second end of the first barrel 10 and a second eyepiece assembly arranged at the second end of the second barrel 20;

[0107] A light supplement assembly, the light supplement assembly supplements light for the first objective assembly 11 or the second objective assembly 21;

[0108] A handheld assembly 30, the handheld assembly 30 is connected between the first barrel 10 and the second barrel 20, and is adjacent to the first eyepiece assembly and the second eyepiece assembly;

[0110] In the present example, the light supplement assembly and the light supplement focusing roller are both arranged on the handheld assembly 30, and the light supplement focusing roller can directly adjust the light supplement assembly, and the target of the adjustment can be the brightness, focal point position, etc. of the light supplement assembly. Moreover, the number of light supplement focusing rollers is one-to-one corresponding to the number of light supplement assemblies, and the number of focusing rollers is less than or equal to the number of objective assemblies.
