DETAILED DESCRIPTION

[0037] To make the objectives, technical solutions, and advantages of the present application clearer, further detailed explanations are made below with reference to the drawings and embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0038] The technical solutions disclosed in the various embodiments of the present application are described in detail below with reference to the drawings.

[0039] To solve the problem of low flexibility and poor portability of the monocular handheld observation device in use in the related art, the present application provides a monocular handheld observation device.

[0040] The monocular handheld observation device provided by the present application comprises a columnar housing, a lens, an image sensor, and an adjusting mechanism. The first end of the columnar housing is an observation end. The lens is arranged at the second end of the columnar housing. The image sensor is arranged in the columnar housing and located between the first end of the columnar housing and the second end of the columnar housing. The lens and / or the image sensor are movably arranged in the columnar housing.

[0041] The adjusting mechanism comprises a transmission assembly and a control. The control is movably arranged at the observation end. At least part of the control is exposed outside the columnar housing. The control is connected with the lens and / or the image sensor through the transmission assembly and drives the lens and / or the image sensor to move through the transmission assembly to adjust the focal length between the lens and the image sensor.

[0042] The columnar housing has a grip. The grip is located between the lens and the control.

[0043] The monocular handheld observation device disclosed by the embodiments of the present application sets the control knob at the observation end of the columnar shell, so that when the user holds the monocular handheld observation device with one hand to view the image, the control knob and the user's thumb and index finger are located on one side of the observation end. Therefore, when the user needs to adjust the focal length between the lens and the image sensor to adjust the performance of viewing the image, the user can operate the control knob by the thumb or index finger of the hand holding the monocular handheld observation device, so that the function of single-handed holding and focusing is realized, and the operation is more convenient. Single-handed holding and focusing is conducive to quickly capturing the changing scene, thereby improving the flexibility of the user using the monocular handheld observation device. In addition, single-handed holding and focusing is conducive to the operation of the user in a narrow space or a crowded environment, thereby improving the portability of the monocular handheld observation device.

[0044] As described above, in the monocular handheld observation device disclosed by the present application, the control knob of the adjusting mechanism is connected with the lens and / or the image sensor through the transmission assembly. The following will be described in detail by examples.

[0045] Please refer to FIGS. 1a-6, the embodiments of the present application disclose a monocular handheld observation device, the disclosed monocular handheld observation device is a kind of observation instrument with single lens, it is easy to hand-held operation, for example, monocular handheld observation device can be monocular telescope, bird watching mirror, night vision instrument, handheld thermal imager, etc., the embodiments of the present application do not limit the type of monocular handheld observation device.

[0046] As shown in FIGS. 1a-1c, the monocular handheld observation device disclosed by the embodiments of the present application includes a columnar shell 100, a lens 200, an image sensor and an adjusting mechanism 300. The columnar shell 100 can provide a mounting base for other components of the monocular handheld observation device. The first end 110 of the columnar shell 100 can be an observation end, which faces the user when the user uses the monocular handheld observation device, and the user can view the image through the observation end. The observation end can be provided with a display module 500, and the user can view the image through the display module 500.

[0047] The second end 120 of the columnar shell 100 can be the light inlet end of the monocular handheld observation device when shooting, and the lens 200 is arranged at the second end 120 of the columnar shell 100. The first end 110 of the columnar shell 100 and the second end 120 of the columnar shell 100 can be arranged opposite to each other. The image sensor is arranged in the columnar shell 100 and located between the first end 110 of the columnar shell 100 and the second end 120 of the columnar shell 100. At least one of the lens 200 and the image sensor is movably arranged in the columnar shell 100.

[0048] As shown in FIGS. 2a-3, the adjusting mechanism 300 includes a transmission assembly 310 and a control 320, the control 320 is movably arranged at the observation end, at least part of the control 320 is exposed outside the cylindrical shell 100, so as to facilitate the user to operate the control 320.

[0049] It should be noted that when the user holds the monocular handheld observation device with one hand, the user's thumb and index finger are located on one side of the observation end of the monocular handheld observation device, and the user is usually used to operate the monocular handheld observation device (for example, adjusting the focal length, image enlargement or reduction, etc. by pressing the keys or rotating the knobs) by using the thumb and index finger. By movably arranging the control 320 at the observation end, it is convenient for the user to operate the control 320 by holding the monocular handheld observation device with one hand.

[0050] The control 320 is connected with at least one of the lens 200 and the image sensor through the transmission assembly 310, and the control 320 drives at least one of the lens 200 and the image sensor to move through the transmission assembly 310, so as to adjust the focal length between the lens 200 and the image sensor. The focal length between the lens 200 and the image sensor is adjusted by adjusting the distance between the lens 200 and the image sensor. The cylindrical shell 100 has a holding portion 130 located between the lens 200 and the control 320, and the user can hold the monocular handheld observation device through the holding portion 130. Wherein, the movement of the lens 200 refers to the movement of the lens assembly for focusing.

[0051] FIGS. 1a-6 show two implementation modes of the control 320 connected with the lens 200 through the transmission assembly 310. The control 320 can also be connected with the image sensor through the transmission assembly 310, or the control 320 can also be connected with both the image sensor and the lens 200, which will be described in detail later.

[0052] In a specific shooting process, light is projected onto the image sensor through the lens 200, so as to be captured by the image sensor to form the image described above. The distance between the lens 200 and the image sensor changes, so that zoom shooting can be realized.

[0053] The monocular handheld observation device disclosed by the embodiments of the present application sets the control 320 at the observation end of the columnar shell 100, so that when the user holds the monocular handheld observation device with one hand to view the image, the control 320 and the thumb and index finger of the user are located at one side of the observation end, so that when the user needs to adjust the focal length between the lens 200 and the image sensor to adjust the performance of viewing the image, the thumb or index finger of the hand holding the monocular handheld observation device can be used to operate the control 320, so that the function of single-handed holding and focusing of the user is realized. Single-handed holding and focusing are beneficial to the user to quickly capture the changing scene, so that the flexibility of the user using the monocular handheld observation device is improved, and single-handed holding and focusing are beneficial to the user to operate in a narrow space or crowded environment, so that the portability of the monocular handheld observation device is improved.

[0054] Optionally, in the first monocular handheld observation device as shown in FIGS. 1a-3, the control 320 can be a scroll key, and in the second monocular handheld observation device as shown in FIGS. 4a-6, the control 320 can be a ring-shaped structure.

[0055] As shown in FIGS. 4a-6, the second monocular handheld observation device can further include a button 400, and the control 320 and the button 400 can be located at the same side of the columnar shell 100.

[0056] It should be noted that the function of the control 320 is to adjust the focal length between the lens 200 and the image sensor, and the function of the button 400 can be to control other functions of the monocular handheld observation device, for example, selecting the resolution, switching the interface, adjusting the brightness, etc. The specific control structure and principle belong to the prior art, and will not be described here.

[0057] The monocular handheld observation device disclosed by the embodiments of the present application sets the button 400, so that the user can realize the corresponding function by operating the button 400, so that the function of the monocular handheld observation device is more powerful. By setting the control 320 and the button 400 at the same side of the columnar shell 100, so that when the user holds the monocular handheld observation device with one hand, the hand holding the monocular handheld observation device can operate the button 400, so that the user can operate the monocular handheld observation device with one hand.

[0058] Different users have different habits of operating the control 320, some users are used to operating the control 320 in a manner of pushing the control 320 to move, therefore, the control 320 can be movably arranged in the columnar shell 100, so that the user moves the control 320 along the columnar shell 100 by pushing the control 320, so that the control 320 drives one of the lens 200 and the image sensor to move, or the control 320 simultaneously drives the lens 200 and the image sensor to move together, thereby adjusting the focal length between the lens 200 and the image sensor.

[0059] Of course, some users are used to rotating the control 320 to operate the control 320, optionally, the control 320 can be rotatably arranged in the columnar shell 100 around the first axis a. The control 320 can be rotatably arranged in the columnar shell 100 through a bearing, or the control 320 can be directly rotatably connected with the columnar shell 100 in a rolling friction manner. In the case that the control 320 rotates around the first axis a in a first direction, the control 320 can drive the lens 200 and / or the image sensor to move closer to each other through the transmission assembly 310; in the case that the control 320 rotates around the first axis a in a second direction, the control 320 can drive the lens 200 and / or the image sensor to move away from each other through the transmission assembly 310, wherein the first direction can be opposite to the second direction.

[0060] For example, when the control 320 rotates clockwise, the lens 200 and / or the image sensor move closer to each other; when the control 320 rotates counterclockwise, the lens 200 and / or the image sensor move away from each other.

[0061] Of course, when the control 320 rotates clockwise, the lens 200 and / or the image sensor can move away from each other; when the control 320 rotates counterclockwise, the lens 200 and / or the image sensor move closer to each other; which is not limited here.

[0062] The monocular handheld observation device disclosed in the embodiments of the present application can adapt to the users who are used to rotating the control 320 by rotatably arranging the control 320 around the first axis a in the columnar shell 100, so that the user operates the control 320 by rotating the control 320, thereby improving the stability of adjusting the focal length between the lens 200 and the image sensor.

[0063] When the user holds the monocular handheld observation device with one hand, if the user rotates the control 320 by using the thumb, the control 320 can be arranged at a position of the columnar shell 100 corresponding to the thumb, and the first axis a can intersect or be skew with the central axis of the columnar shell 100, for example, the first axis a can be perpendicular to the central axis of the columnar shell 100.

[0064] The monocular handheld observation device disclosed by the embodiment of the application is convenient for a user to operate the control 320 by a thumb.

[0065] When the user holds the monocular handheld observation device, the thumb is also used to hold the monocular handheld observation device, thereby improving the stability of holding, and the index finger has higher freedom, and the index finger can not participate in the holding action when the user holds the monocular handheld observation device, and therefore, the index finger is more convenient for the user to operate the control 320. In order to facilitate the user to operate the control 320 by the index finger, optionally, as shown in FIG. 1a and FIG. 6, the first axis a can be parallel to or coincide with the central axis of the cylindrical shell 100, so that it is easier for the user to rotate the control 320 by the index finger.

[0066] It should be noted that the cylindrical shell 100 is a cylindrical member, and the central axis of the cylindrical shell 100 refers to the central axis in the through direction of the cylindrical member.

[0067] The transmission assembly 310 is a transmission component, and has many implementation manners. In the embodiment in which the control 320 moves along the cylindrical shell 100, the transmission assembly 310 can include a transmission rod, the control 320 is directly connected with the lens 200 or the image sensor through the transmission rod, the control 320 can directly drive the lens 200 or the image sensor to move along the cylindrical shell 100, thereby adjusting the focal length between the lens 200 and the image sensor.

[0068] In the embodiment in which the control 320 moves along the cylindrical shell 100, the transmission assembly 310 can also drive the lens 200 and the image sensor to move together. For example, the transmission assembly 310 can include a rotating rod and a moving rod, the center of the rotating rod can be rotationally connected with the cylindrical shell 100, the lens 200 and the image sensor can be respectively connected to two ends of the rotating rod, one end of the moving rod can be connected with the control 320, and the other end of the moving rod can be connected with any one end of the rotating rod. When the control 320 moves, the moving rod is driven to move, the moving rod can drive the rotating rod to rotate around the rotation center of the rotating rod, and the two ends of the rotating rod drive the lens 200 and the image sensor to move in opposite directions, so that the lens 200 and the image sensor located at the two ends of the rotating rod move in opposite directions, thereby adjusting the focal length between the lens 200 and the image sensor.

[0069] In the embodiment in which the control 320 rotates about the first axis a, the transmission component can include a first gear, a second gear, a chain, a first rack, and a second rack. The first gear and the second gear can be rotatably arranged in the columnar housing 100, and the first rack and the second rack can be movably arranged in the columnar housing 100 (the first rack and the second rack can be movably arranged in the columnar housing 100 along the extension direction of the central axis of the columnar housing 100). The control 320 can be connected with the first gear, and the rotation of the control 320 about the first axis a can drive the first gear to rotate. The first gear and the second gear can be connected by the chain, and the rotation of the first gear can drive the second gear to rotate through the chain. The first rack and the second rack are respectively engaged with the second gear, and the first rack and the second rack are located on the opposite sides of the second gear. The lens 200 can be connected with the first rack, and the image sensor can be connected with the second rack. In the case where the control 320 drives the second gear to rotate through the first gear and the chain, the second gear drives the first rack and the second rack to move in opposite directions, so as to make the lens 200 and the image sensor approach or move away from each other.

[0070] Of course, the transmission component can also only include one of the first rack and the second rack. In the case where the control 320 drives the second gear to rotate through the first gear and the chain, the second gear drives one of the lens 200 and the image sensor to move through the first rack or the second rack, so as to realize the approach or movement away of the lens 200 and the image sensor from each other.

[0071] The above embodiments illustrate an embodiment in which the lens 200 and the image sensor are moved to approach or move away from each other along the central axis of the cylindrical housing 100 when the control knob 320 rotates around the first axis a. In another embodiment, the transmission assembly can include an extension rod connected between the lens 200 and the control knob 320, or an extension rod connected between the image sensor and the control knob 320. After the lens 200 or the image sensor is connected to the control knob 320 through the extension rod, the lens 200 or the image sensor can only move relative to the control knob 320 in the extension direction of the extension rod (the extension direction of the control knob 320 can be parallel or coincident with the central axis of the cylindrical housing 100), and the lens 200 or the image sensor and the control knob 320 cannot rotate relative to each other around the extension direction of the extension rod (i.e., the lens 200 or the image sensor and the control knob 320 can rotate around the extension direction of the extension rod at the same time, or neither of them can rotate around the extension direction of the extension rod). The lens 200 or the image sensor can be threadedly connected to the cylindrical housing 100. When the control knob 320 rotates, the lens 200 or the image sensor is driven to rotate relative to the cylindrical housing 100 through the extension rod. Since the lens 200 or the image sensor is threadedly connected to the cylindrical housing 100, when the lens 200 or the image sensor rotates relative to the cylindrical housing 100, the lens 200 or the image sensor will displace relative to the cylindrical housing 100 along the extension direction of the rotation axis of the lens 200 or the image sensor. At this time, the extension rod will be extended or retracted, so as to adjust the focal length between the lens 200 and the image sensor.

[0072] Of course, the lens 200 and the image sensor can be connected to the control knob 320 through an extension rod respectively, and the lens 200 and the image sensor can be threadedly connected to the cylindrical housing 100, and the screwing direction of the lens 200 and the cylindrical housing 100 is opposite to the screwing direction of the image sensor and the cylindrical housing 100. Thus, when the control knob 320 rotates around the first axis a, the lens 200 and the image sensor can be driven to rotate, so as to move the lens 200 and the image sensor in opposite directions along the extension direction of the rotation axis of the lens 200 or the image sensor, thereby adjusting the focal length between the lens 200 and the image sensor.

[0073] As shown in FIGS. 2a-3 and 5a-6, to improve the transmission accuracy of the transmission assembly 310, the transmission assembly 310 can optionally include a transmission rod 311 and a nut 312. The first end of the transmission rod 311 can be connected to the lens 200 or the image sensor, and the second end of the transmission rod 311 can have external threads. The nut 312 can be rotatably disposed about the second axis b of the cylindrical housing 100, which can be parallel to or coincident with the central axis of the cylindrical housing 100. The nut 312 can be sleeved on the second end of the transmission rod 311 and threadedly engaged with the second end of the transmission rod 311. The control knob 320 can be connected to the nut 312. When the control knob 320 is rotated about the first axis a, the control knob 320 can drive the nut 312 to rotate about the second axis b.

[0074] It should be noted that the transmission assembly 310 can be disposed in the cylindrical housing 100, the nut 312 can be rotatably disposed about the second axis b of the cylindrical housing 100, and the nut 312 can not move in the direction of extension of the second axis b. The transmission rod 311 can be movably disposed along the central axis direction of the cylindrical housing 100, and the cylindrical housing 100 can limit the rotation of the transmission rod 311 about the central axis direction of the cylindrical housing 100. Alternatively, when the transmission rod 311 is connected to the lens 200 or the image sensor, the lens 200 or the image sensor can limit the rotation of the transmission rod 311 about the central axis direction of the cylindrical housing 100.

[0075] As shown in FIG. 2e, the nut 312 can have a relatively large length. One end of the nut 312 can be threadedly engaged with the second end of the transmission rod 311, and the second end of the nut 312 can be rotatably connected to the rotating pin 330, which can be disposed in the cylindrical housing 100. The nut 312 can be installed under the joint action of the rotating pin 330 and the second end of the transmission rod 311.

[0076] Specifically, as shown in FIGS. 2b and 5b, the monocular handheld observation device further includes a limiting plate 600 and a sensor mounting plate 700, and the image sensor is fixedly disposed on the sensor mounting plate 700. The limiting plate 600 is fixedly connected to the sensor mounting plate 700. As shown in FIG. 2c, one end of the sensor mounting plate 700 facing the control knob 320 is provided with a positioning column 720. As shown in FIG. 2d, one end of the limiting plate 600 facing the sensor mounting plate 700 is provided with a positioning hole 620. The positioning column 720 cooperates with the positioning hole 620, and the limiting plate 600 and the sensor mounting plate 700 are fixedly connected through the positioning column 720 and the positioning hole 620.

[0077] As shown in FIG. 2b and FIG. 5b, the limiting plate 600 is provided with a limiting post 610 at one end of the limiting plate 600 facing the control handle 320, and the transmission rod 311 is provided with a limiting groove at a position corresponding to the limiting post 610 at one end of the transmission rod 311 close to the control handle 320; the limiting post 610 is limited in the limiting groove, and the limiting post 610 is in sliding fit with the limiting groove along the length direction of the limiting post 610.

[0078] In the embodiment of the present application, one end of the limiting plate 600 is in sliding fit with the limiting groove along the length direction of the limiting post 610, so that the transmission rod 311 can move along the length direction of the limiting post 610.

[0079] Further, the sensor mounting plate 700 is fixedly connected with the first end 110 of the columnar shell 100, and the other end of the limiting plate 600 is fixedly connected with the sensor mounting plate 700, so that the limiting plate 600 is fixedly connected with the columnar shell 100 and cannot move relative to the columnar shell 100. Since the transmission rod 311 can move along the length direction of the limiting post 610, the transmission rod 311 can move along the length direction of the columnar shell 100 and cannot rotate around the central axis direction of the columnar shell 100.

[0080] The monocular handheld observation device disclosed in the embodiment of the present application sets the transmission assembly 310 to include the transmission rod 311 and the nut 312, so that the first end of the transmission rod 311 is connected with the lens 200 or the image sensor, and the second end of the transmission rod 311 is in threaded fit with the nut 312, so that when the control handle 320 drives the nut 312 to rotate around the second axis b, the transmission rod 311 can drive the lens 200 or the image sensor to move through the threaded fit between the nut 312 and the second end of the transmission rod 311. Since the threaded fit has relatively high precision, the transmission precision of the transmission assembly 310 is relatively high, and the moving precision of the lens 200 or the image sensor is relatively high.

[0081] As shown in FIG. 1b to FIG. 1d, the columnar shell 100 extends the first mounting plate 170 and the second mounting plate 180 towards the inside of the columnar shell 100, the first mounting plate 170 is provided with the first mounting hole 171, and one end of the transmission rod 311 close to the display module 500 passes through the first mounting hole 171; the second mounting plate 180 is provided with the second mounting hole 181, and one end of the rotating pin 330 close to the display module 500 passes through the second mounting hole 181; in this way, the control handle 320 is rotatably arranged on the columnar shell 100 around the first axis a.

[0082] The control handle 320 can be fixedly connected with the end surface of the nut 312, so that the control handle 320 can drive the nut 312 to rotate around the second axis b in the case of rotating around the first axis a, and at this time, the first axis a can coincide with the second axis b.

[0083] Of course, the control 320 can also be engaged with the nut 312 through external tooth structure to achieve transmission, and embodiments of the present application do not make specific limitations on the matching mode of the control 320 and the nut 312.

[0084] In order to reduce the space occupation of the components of the monocular handheld observation device, optionally, the control 320 can be sleeved on the nut 312, and the control 320 can be limited in cooperation with the nut 312 in the direction around the second axis b to limit the relative rotation of the control 320 and the nut 312 in the direction around the second axis b, so that the control 320 will drive the nut 312 to rotate synchronously when rotating. Since the control 320 is sleeved on the nut 312, it is beneficial to reduce the space occupation of the control 320 and the nut 312 of the monocular handheld observation device.

[0085] Specifically, the limited cooperation of the control 320 and the nut 312 in the direction around the second axis b can be limited by a limiting pin. Of course, in another embodiment, as shown in FIG. 2f, the inner wall contour shape of the control 320 can be matched with the contour shape of the outer periphery of the nut 312, and the contour shape of both can be prismatic. The limited cooperation of the control 320 and the nut 312 in the direction around the second axis b can be realized by the limited cooperation of the inner wall of the control 320 and the outer periphery of the nut 312.

By setting the control handle 320 as a ring structure and sleeving it on the columnar shell 100, the user can operate the control handle 320 at any angle when holding the monocular handheld observation device, so that the operation of the control handle 320 is more convenient.
