Description

Technical Field

[0001] The utility model relates to the technical field of imaging equipment, and more specifically to a supporting body and an objective lens assembly of a monocular handheld device. Background Art

[0002] In the field of outdoor sports and outdoor observation, infrared thermal imaging technology can help users quickly identify and find targets with its unique principle. However, since infrared thermal imaging relies on temperature difference imaging, in scenes where the temperature difference of the target is not large, the infrared thermal imaging has low contrast and poor ability to distinguish details. Starlight night vision technology can achieve clear imaging in a low-light environment with only starlight, which is conducive to the identification and investigation of detailed scenes and environments. At the same time, the large array of low-light detectors can make up for the problem of short infrared recognition distance. Under outdoor use conditions, the combination of infrared thermal imaging and starlight night vision will have obvious advantages in image quality, adaptability and field of view.

[0003] The lenses of the multi-light fusion monocular handheld devices on the market are mostly arranged in a triangle, the overall appearance is not coordinated, and the grip is poor. In addition, most handheld infrared lenses and visible light lenses need to extend out of the entire lens barrel structure. When focusing, you need to pinch the lens head with your fingers and turn it to focus, which is inconvenient to operate. If you wear gloves outdoors in winter, focusing is even more difficult. In addition, due to the limitation of the overall structure size, the two lenses are very close, so many monocular handheld devices usually only have one lens that can be focused, which greatly limits the user's usage scenarios.

[0004] In summary, how to effectively solve the problem that multi-light monocular handheld devices are difficult to meet the needs of adjusting the focal length of each lens individually is a problem that technical personnel in this field need to solve. Utility Model Content

DETAILED DESCRIPTION

[0039] The embodiment of the utility model discloses a supporting body and an objective lens assembly of a monocular handheld device, so as to facilitate the individual focal length adjustment of each lens.

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] In some embodiments, see Figure 1-Figure 6The monocular handheld device provided in this embodiment includes a body component 100, an eyepiece component 200 and an objective lens component 300. Among them, the body component 100 is the main holding part of the monocular handheld device, on which various function buttons can be set, and the circuit board and battery of the monocular handheld device can be arranged inside the body component 100. The eyepiece component 200 is arranged at the rear end of the body component 100, and its specific structure can refer to the conventional monocular handheld device, which will not be repeated here. It can be understood that the rear end here refers to the end of the monocular handheld device close to the user's eyes when it is in use, and the corresponding front end is the end away from the user's eyes. The objective lens assembly 300 is arranged at the front end of the fuselage assembly 100. The objective lens assembly 300 includes a supporting body 310, a first lens 320, a second lens 330, a first focusing component 340 and a second focusing component 350. The supporting body 310 is arranged at the fuselage assembly 100 for installing the first lens 320, the second lens 330, the first focusing component 340 and the second focusing component 350. The specific structure is set according to the installation needs. The first lens 320 and the second lens 330 are respectively slidably arranged on the supporting body 310 along their respective optical axis directions, so that the first lens 320 and the second lens 330 can move forward and backward along the corresponding optical axis respectively, change the distance from the mirror surface of the first lens 320 and the second lens 330 to the target surface of the detector, and realize focal length adjustment to achieve clear imaging. Specifically, the optical axes of the first lens 320 and the second lens 330 are parallel. The first lens 320 and the second lens 330 can realize multi-light fusion, which includes but is not limited to infrared lens and low-light lens, such as a combination of infrared lens and starlight night vision lens. The first focusing component 340 and the second focusing component 350 are rotatably arranged on the supporting body 310 and are restricted from axial movement by the supporting body 310, that is, the first focusing component 340 and the second focusing component 350 can both rotate relative to the supporting body 310, but cannot move axially. The first focusing component 340 is threadedly connected to the first lens 320, and the rotation of the first focusing component 340 is converted into the linear movement of the first lens 320 through threaded matching to achieve focal length adjustment. The second focusing component 350 is threadedly connected to the second lens 330, and the rotation of the second focusing component 350 is converted into the linear movement of the second lens 330 through threaded matching to achieve focal length adjustment. The first lens 320 and the second lens 330 can achieve separate focusing. Compared with the synchronous focusing of the two, for different situations of the first lens 320 and the second lens 330, due to the difference in the imaging principles of the two lenses, simultaneous focusing cannot achieve simultaneous clarity of the two lenses. Therefore, in the field of multi-light fusion, independent focusing is more widely applicable. In addition, the rotation axes of the first focusing member 340 and the second focusing member 350 are coaxial. It should be noted that the rotation axis of the first focusing member 340 refers to the rotation axis thereof rotating relative to the supporting body 310, and the rotation axis of the second focusing member 350 refers to the rotation axis thereof rotating relative to the supporting body 310.The rotation axes of the first focusing component 340 and the second focusing component 350 are coaxially arranged to facilitate the layout of the two.

[0042] In the monocular handheld device, the first lens 320 and the second lens 330 are respectively threadedly connected with the first focusing component 340 and the second focusing component 350, and the axial movement of the first focusing component 340 and the second focusing component 350 on the supporting body 310 is limited, then by screwing the first focusing component 340 and the second focusing component 350, the first lens 320 and the second lens 330 can be driven to move forward and backward, and the distance from the mirror surface of the first lens 320 and the second lens 330 to the target surface of the detector can be changed to achieve clear imaging, that is, the monocular handheld device can achieve the single focal length adjustment of a single lens. And the rotation axis of the first focusing component 340 and the second focusing component 350 are coaxial, the structure is simple and compact, and it is convenient for users to operate, so as to achieve rapid focusing of the first lens 320 and the second lens 330, enhance the discovery, focusing, and observation capabilities of the monocular handheld device, and improve the user experience. And the objective lens assembly 300 has a compact structure, high integrity, strong modularity, and is convenient for product upgrades in the later stage.

[0043] In some embodiments, see Figure 5 and Figure 6 The support body 310 provided by the utility model is used to rotatably install the first focusing component 340 and the second focusing component 350 of the monocular handheld device. The support body 310 includes a front flange 311, a middle piece 313 and a rear flange 312 arranged in sequence along the axial direction. The front and rear ends of the middle piece 313 are respectively used to rotatably connect the first focusing component 340 and the second focusing component 350, and the first focusing component 340 is clamped between the front flange 311 and the middle piece 313 to form an axial limit for the first focusing component 340, and the second focusing component 350 is clamped between the rear flange 312 and the middle piece 313 to form an axial limit for the second focusing component 350. It can be understood that the first focusing component 340 and the second focusing component 350 are respectively used to be rotatably connected to the front and rear ends of the middle piece 313, which means that the first focusing component 340 and the second focusing component 350 are respectively installed at the front and rear ends of the middle piece 313 and can rotate relative to the middle piece 313. The first focusing component 340 cannot move axially under the axial limitation of the front flange 311 and the middle piece 313, but can rotate around the axial direction. The second focusing component 350 cannot move axially under the axial limitation of the rear flange 312 and the middle piece 313, but can rotate around the axial direction.

[0044] Using the support body 310 of the monocular handheld device provided by the utility model, the first focusing component 340 and the second focusing component 350 can be rotatably installed on the support body 310, and the first focusing component 340 is clamped between the front flange 311 and the middle piece 313 to form an axial limit to prevent its axial movement. The second focusing component 350 is clamped between the rear flange 312 and the middle piece 313 to form an axial limit to prevent its axial movement. The front and rear ends of the middle piece 313 are respectively used to rotatably connect the first focusing component 340 and the second focusing component 350, which can separate the first focusing component 340 from the second focusing component 350, and the focusing processes do not interfere with each other. That is, by respectively rotating the first focusing component 340 and the second focusing component 350, the first lens 320 and the second lens 330 of the monocular handheld device are driven to move forward and backward accordingly, and the distance between the mirror surface of the first lens 320 and the second lens 330 and the target surface of the detector is changed to achieve clear imaging, that is, the monocular handheld device can realize the individual focal length adjustment of a single lens. The discovery, focusing, and observation capabilities of the monocular handheld device are enhanced, and the user experience is improved.

[0045] In some embodiments, the front flange 311 is connected to the middle piece 313 by fasteners such as screws to achieve axial limitation of the first focusing component 340, and the rear flange 312 is connected to the middle piece 313 by fasteners such as screws to achieve axial limitation of the second focusing component 350. The first focusing component 340 and the second focusing component 350 are rotatably disposed at the front and rear ends of the middle piece 313, respectively, and cannot move axially under the axial limitation of the middle piece 313 and the corresponding front flange 311 and rear flange 312. As set above, there is no need to set a rotating connection structure corresponding to the first focusing component 340 and the second focusing component 350, and assembly is convenient.

[0046] In other embodiments, the front flange 311 and the rear flange 312 are not directly connected to the middle piece 313, but are indirectly connected through the first focusing component 340 and the second focusing component 350. That is, the front and rear ends of the first focusing component 340 are rotatably connected to the front flange 311 and the middle piece 313, and are restricted from front and rear axial movement by the front flange 311 and the middle piece 313. The front and rear ends of the second focusing component 350 are rotatably connected to the middle piece 313 and the rear flange 312, and are restricted from front and rear axial movement by the middle piece 313 and the rear flange 312. As set above, the middle piece 313 does not need to be directly connected to the front flange 311 and the rear flange 312, which simplifies the internal structure. In other embodiments, the front flange 311 and the middle piece 313 can be connected by fasteners such as screws, the rear flange 312 and the middle piece 313 can be connected by fasteners such as screws, the first focusing component 340 can be directly rotatably connected to the front flange 311 or the middle piece 313, and the second focusing component 350 can be directly rotatably connected to the rear flange 312 or the middle piece 313.

[0047] In some embodiments, the end surface of the front flange 311 facing the middle piece 313 is directly opposite to one end of the edge of the first lens 320 and the second lens 330; the end surface of the rear flange 312 facing the middle piece 313 is directly opposite to the other end of the edge of the first lens 320 and the second lens 330. When the first lens 320 is driven to move axially by screwing the first focusing component 340, when it moves forward and backward to abut against the front flange 311 or the rear flange 312, further axial movement in the corresponding direction is restricted. Similarly, when the second lens 330 is driven to move axially by screwing the second focusing component 350, when it moves forward and backward to abut against the front flange 311 or the rear flange 312, further axial movement in the corresponding direction is restricted. As set above, the front flange 311 and the rear flange 312 can serve as the limit structure of the axial movement limit of the first lens 320 and the second lens 330, control the movement stroke of the first lens 320 and the second lens 330, and improve the safety of the device. The front flange 311 and the rear flange 312 integrate multiple functions, further simplifying the structure. Specifically, a step surface may be provided on the front flange 311 and / or the rear flange 312 to abut against the steps provided on the first lens 320 and the second lens 330 respectively to limit the position. In other embodiments, the movement stroke limit may also be achieved by the thread length of the first lens 320 and the second lens 330.

[0048] In some embodiments, the rear flange 312 is used to set the first lens 320 and the second lens 330 of the monocular handheld device. The first lens 320 and the second lens 330 are installed on the same structural member to avoid the non-parallel optical axis caused by installation and debugging, thereby improving the dual-light fusion effect of the product.

[0049] In some embodiments, the rear flange 312 is provided with a first mounting position and a second mounting position corresponding to the first lens 320 and the second lens 330, respectively, and a clearance portion is provided on the side wall of the first mounting position corresponding to the position of the first focusing component 340, so that the mounting position accuracy of the first lens 320 is ensured, and the first focusing component 340 is convenient for contact and cooperation with the first lens 320. Correspondingly, a clearance portion is also provided on the side wall of the second mounting position corresponding to the position of the second focusing component 350, so that the second focusing component 350 is convenient for contact and cooperation with the second lens 330.

[0050] In some embodiments, see Figure 7The first mounting position includes a first convex ring 3121 arranged on the end surface of the rear flange 312 facing the middle piece 313, and the first convex ring 3121 is used to install the first lens 320. The second mounting position includes a second convex ring 3122 arranged on the end surface of the rear flange 312 facing the middle piece 313, and the second convex ring 3122 is used to install the second lens 330. The side walls of the first convex ring 3121 and the second convex ring 3122 are respectively provided with openings to form a void avoidance portion, and the middle piece 313 and the front flange 311 are respectively provided with through holes corresponding to the first convex ring 3121 and the second convex ring 3122, and the first convex ring 3121 and the second convex ring 3122 are respectively penetrated through the corresponding through holes. By setting the first convex ring 3121 and the second convex ring 3122 on the rear flange 312, the first lens 320 can move forward and backward along the first convex ring 3121, and the second lens 330 can move forward and backward along the second convex ring 3122. The first convex ring 3121 and the second convex ring 3122 can respectively guide and limit the forward and backward movement of the first lens 320 and the second lens 330, so that the forward and backward movement of the first lens 320 and the second lens 330 is more stable and reliable.

[0051] In addition, a sealing ring may be provided between the first convex ring 3121 and the first lens 320 for sealing, and a sealing ring may be provided between the second convex ring 3122 and the second lens 330 for sealing.

[0052] In some embodiments, the front flange 311 and the rear flange 312 are detachably connected to the middle piece 313. The detachable connection facilitates assembly, and through the connection between the front flange 311 and the middle piece 313, and the connection between the rear flange 312 and the middle piece 313, an installation space for installing the first focusing component 340 and the second focusing component 350 is formed, and reliable axial limitation can be achieved.

[0053] In some embodiments, a first limiting column 314 is provided on the end surface of the middle piece 313 facing the front flange 311 and / or the end surface of the front flange 311 facing the middle piece 313. The first limiting column 314 limits the distance between the front flange 311 and the middle piece 313. When the middle piece 313 and the front flange 311 are fixed, under the axial limiting action of the first limiting column 314, the distance between the middle piece 313 and the front flange 311 is limited, thereby satisfying the installation of the first focusing component 340 and forming an effective axial limit on it. Specifically, the first limiting column 314 limits the distance between the front flange 311 and the middle piece 313 to meet the clearance fit with the first focusing component 340, thereby realizing the axial limit of the first focusing component 340 and facilitating the operation of rotating the first focusing component 340 during focusing.

[0054] In some embodiments, a second limiting column 315 is provided on the end surface of the middle piece 313 facing the rear flange 312 and / or the end surface of the rear flange 312 facing the middle piece 313. The second limiting column 315 limits the distance between the rear flange 312 and the middle piece 313. When the middle piece 313 and the rear flange 312 are fixed, under the axial limiting action of the second limiting column 315, the distance between the middle piece 313 and the rear flange 312 is limited, thereby meeting the installation of the second focusing component 350 and forming an effective axial limit on it. Specifically, the second limiting column 315 limits the distance between the rear flange 312 and the middle piece 313 to meet the clearance fit with the second focusing component 350, thereby achieving the axial limit of the second focusing component 350 and facilitating the operation of rotating the second focusing component 350 during focusing.

[0055] In some embodiments, the first limiting column 314 is provided with a screw hole and the middle piece 313 is connected to the front flange 311 by screws; the second limiting column 315 is provided with a screw hole and the middle piece 313 is connected to the rear flange 312 by screws. The first limiting column 314 is used to connect the middle piece 313 to the front flange 311 while playing the role of axial limiting. The integrated setting of different functions further simplifies the structure. Taking the first limiting column 314 being provided on the middle piece 313 as an example, a through hole is provided at a position corresponding to the first limiting column 314 on the front flange 311, and a screw passes through the through hole and is locked with the screw hole on the first limiting column 314. The head end of the screw is blocked at the front end of the front flange 311, thereby fixing the middle piece 313 to the front flange 311. The setting of the second limiting column 315 is similar to that of the first limiting column 314, and will not be repeated here. The number of the first limiting pillars 314 and the second limiting pillars 315 can be set according to the actual needs, and preferably at least two are set along the circumferential direction to achieve axial limiting and locking from different directions.

[0056] In some embodiments, the first limiting column 314 and the second limiting column 315 are symmetrically arranged on the two end surfaces of the middle piece 313. The first limiting column 314 and the second limiting column 315 are symmetrically arranged, the forces on both ends of the middle piece 313 are more balanced, and the overall structure is more stable and reliable.

[0057] Furthermore, the first limiting column 314 is connected to the screw hole on the second limiting column 315, and the front flange 311 and the rear flange 312 are connected by screws and the middle piece 313 is pressed. The screw passes through the screw hole, and the tail end of the screw is locked with one of the front flange 311 and the rear flange 312, and the head end of the screw is blocked outside the other, so that the screw fixes the front flange 311 and the rear flange 312, and presses the middle piece 313 between the front flange 311 and the rear flange 312, so that the three are fixed. As set above, the number of screws required for assembly is small, which simplifies the operation steps.

[0058] In some embodiments, the middle piece 313 includes a main body 3131 and a flange 3132 formed by radially outwardly protruding from the middle of the outer circumferential surface of the main body 3131, and the parts of the main body 3131 located on the front and rear sides of the flange 3132 are respectively used to rotatably cover the first focusing component 340 and the second focusing component 350, and the front and rear end surfaces of the flange 3132 and / or the front and rear end surfaces of the main body 3131 are used to respectively abut against the rear end surface of the first focusing component 340 and the front end surface of the second focusing component 350. By providing the flange 3132, the first focusing component 340 and the second focusing component 350 are completely separated, and the axial directions of the two can be limited respectively. The overall structure is simple and can be quickly positioned during assembly. Specifically, the parts of the main body 3131 located on the front and rear sides of the flange 3132 are respectively provided with sealing rings between the first focusing component 340 and the second focusing component 350.

[0059] Specifically, the inner wall of the first focusing component 340 is provided with a first focusing boss, which can be specifically annular, and the front end surface of the first focusing boss is used to abut against the limiting surface on the front flange 311 for axial limiting, and the rear end surface of the first focusing boss is used to abut against the front end surface of the main body 3131 for axial limiting. Correspondingly, the inner wall of the second focusing component 350 is provided with a second focusing boss, which can be specifically annular, and the front end surface of the second focusing boss is used to abut against the rear end surface of the main body 3131 for axial limiting, and the rear end surface of the second focusing boss is used to abut against the limiting surface on the rear flange 312 for axial limiting.

[0060] In some embodiments, the support body 310 provided by the utility model includes a front flange 311, a rear flange 312 and a middle piece 313 disposed between the front flange 311 and the rear flange 312, the first lens 320 and the second lens 330 are both disposed on the rear flange 312, the rear flange 312 can be disposed on the body assembly 100, the front flange 311 and the rear flange 312 are respectively connected to the two ends of the middle piece 313, and the first focusing component 340 is clamped between the front flange 311 and the middle piece 313, and the second focusing component 350 is clamped between the rear flange 312 and the middle piece 313. The rear flange 312 can be detachably connected to the body assembly 100, such as screw connection, which plays a supporting role and is convenient for disassembly and assembly. The front flange 311 and the rear flange 312 can also be detachably connected to the middle piece 313, such as screw connection. By connecting the front flange 311 and the middle piece 313, the first focusing component 340 is clamped between the front flange 311 and the middle piece 313 to form an axial limit to prevent its axial movement. Of course, the axial limit should not affect the rotation of the first focusing component 340. Similarly, by connecting the rear flange 312 and the middle piece 313, the second focusing component 350 is clamped between the rear flange 312 and the middle piece 313 to form an axial limit to prevent its axial movement. Of course, the axial limit should not affect the rotation of the second focusing component 350. In addition, the middle piece 313 can separate the first focusing component 340 from the second focusing component 350, and the focusing processes do not interfere with each other. In other embodiments, the support body 310 can also adopt a shell, and mounting grooves corresponding to the first focusing component 340 and the second focusing component 350 are set on the shell, and the first focusing component 340 and the second focusing component 350 are respectively rotatably installed in the mounting grooves.

[0061] Based on the support body provided in the above embodiments, the present invention further provides an objective lens assembly, which includes any one of the support bodies in the above embodiments. Since the objective lens assembly adopts the support body in the above embodiments, please refer to the above embodiments for the beneficial effects of the objective lens assembly.

[0062] Further, the objective lens assembly 300 includes a first lens 320, a second lens 330, a first focusing component 340 and a second focusing component 350, the optical axes of the first lens 320 and the second lens 330 are parallel, and the first lens 320 and the second lens 330 can move forward and backward along the corresponding optical axis respectively, change the distance from the mirror surface of the first lens 320 and the second lens 330 to the target surface of the detector, and realize focal length adjustment to achieve clear imaging. The first lens 320 and the second lens 330 can realize multi-light fusion, which includes but is not limited to infrared lens and low-light lens, such as a combination of infrared lens and starlight night vision lens. The first focusing component 340 and the second focusing component 350 are coaxial and sequentially sleeved outside the first lens 320 and the second lens 330 along the axial direction, and the first focusing component 340 and the second focusing component 350 can rotate around the axial direction respectively. It should be noted that the first focusing component 340 and the second focusing component 350 can be either in a closed annular shape or include a partial annular shape, that is, an unclosed structure. When the first focusing component 340 rotates around the axis, it can drive the first lens 320 to move forward and backward to change the distance from the mirror surface of the first lens 320 to the target surface of the detector, and realize the independent focusing of the first lens 320; when the second focusing component 350 rotates around the axis, it can drive the second lens 330 to move forward and backward to change the distance from the mirror surface of the second lens 330 to the target surface of the detector, and realize the independent focusing of the second lens 330. The first lens 320 and the second lens 330 of the objective lens assembly 300 can realize independent focusing. Compared with the synchronous focusing of the two, for different situations of the first lens 320 and the second lens 330, due to the difference in the imaging principles of the two lenses, simultaneous focusing cannot achieve simultaneous clarity of the two lenses. Therefore, in the field of multi-light fusion, independent focusing is more widely applicable. In addition, the rotation axis of the first focusing component 340 and the second focusing component 350 are coaxial. The coaxial arrangement of the rotation axis of the first focusing component 340 and the second focusing component 350 facilitates the layout of the two.

[0063] In some embodiments, the first focusing component 340 is threadedly connected to the first lens 320, and the rotation of the first focusing component 340 is converted into the linear movement of the first lens 320 through threaded matching to achieve focal length adjustment. The second focusing component 350 is threadedly connected to the second lens 330, and the rotation of the second focusing component 350 is converted into the linear movement of the second lens 330 through threaded matching to achieve focal length adjustment. It can be understood that the first lens 320 and the second lens 330 can move axially, and the rotation of the two around their respective axes is limited, so that the rotation of the first focusing component 340 and the second focusing component 350 can be converted into the axial movement of the first lens 320 and the second lens 330 through threaded matching. The use of threaded matching has high adjustment accuracy, convenient assembly, and a simple and compact structure.

[0064] In some embodiments, see Figure 8 and Fig. 9 , the first focusing component 340 is a first adjustment ring, which is sleeved on the outside of the first lens 320 and the second lens 330, and the outer wall of the first lens 320 is provided with a first external thread 321, and the inner wall of the first adjustment ring is provided with a first internal thread 341 that matches the first external thread 321. The first focusing component 340 adopts a ring structure, and the first lens 320 and the second lens 330 are arranged in the ring, which is convenient for operating the first focusing component 340. The first external thread 321 is arranged on the first lens 320, and the first internal thread 341 is arranged on the first focusing component 340, which has a simple structure, convenient assembly, and reliable transmission. And the size of the first adjustment ring set as above is obviously larger than the outer diameter of a single lens, the hand holding area is large, and the grip is more comfortable when focusing. It can be understood that the thread length of the first external thread 321 on the first lens 320 is set accordingly according to the pitch and the focusing range, that is, the stroke of the first lens 320, usually a small section is sufficient. In other embodiments, an annular groove may be provided on the first lens 320, and an external thread may be provided in the annular groove. At least a portion of the first focusing component 340 may be inserted into the annular groove and provided with an internal thread, so that threaded fitting can also be achieved.

[0065] In some embodiments, see Fig.10 The second focusing component 350 is a second adjustment ring, which is sleeved outside the first lens 320 and the second lens 330. The outer wall of the second lens 330 is provided with a second outer thread 331, and the inner wall of the second adjustment ring is provided with a second inner thread that matches the second outer thread 331. The cooperation between the second focusing component 350 and the second lens 330 can be the same as the cooperation between the first focusing component 340 and the first lens 320, which will not be repeated here.

[0066] In some embodiments, see Figure 11-13, the first focusing component 340 is a first adjustment ring, which is sleeved outside the first lens 320 and the second lens 330. One of the outer wall of the first lens 320 and the inner wall of the first adjustment ring is provided with a first slide groove 322, and the other is provided with a first protrusion 342 that cooperates with the first slide groove 322. This embodiment is different from the above-mentioned first adjustment ring and the first lens 320 threadedly matched in that in this embodiment, the first slide groove 322 is provided on one of the matching surfaces of the first adjustment ring and the first lens 320, and the first protrusion 342 is provided on the other. It can be understood that the first lens 320 can move in the axial direction, and its rotation around its own axis is limited, so that the rotation of the first adjustment ring can be converted into the axial movement of the first lens 320 through the cooperation of the first slide groove 322 and the first protrusion 342. When the first adjustment ring rotates, the first slide groove 322 cooperates with the first protrusion 342 to drive the first lens 320 to move axially. By using the cooperation between the first slide groove 322 and the first protrusion 342, the first adjustment ring and a small part of the outer shell structure of the first lens 320 can be improved, which is convenient for processing. Specifically, the outer peripheral surface of the first lens 320 is provided with a first slide groove 322, and the inner wall of the first adjustment ring is provided with a first protrusion 342, and the first slide groove 322 extends in a spiral. When the first adjustment ring rotates, since its axial displacement is limited, the first protrusion 342 moves on a specific plane perpendicular to the axial direction. When the first protrusion 342 moves in the first slide groove 322, it drives the first lens 320 to move forward and backward, thereby achieving focusing.

[0067] In some embodiments, the second focusing component 350 is a second adjustment ring, which is sleeved outside the first lens 320 and the second lens 330. One of the outer wall of the second lens 330 and the inner wall of the second adjustment ring is provided with a second slide groove, and the other is provided with a second protrusion that cooperates with the second slide groove. The cooperation between the second focusing component 350 and the second lens 330 can be the same as the cooperation between the first focusing component 340 and the first lens 320, which will not be repeated here.

[0068] In some implementations, the first focusing component 340 and the second focusing component 350 are sequentially sleeved on the outer periphery of the support body 310 along the axial direction, and the first focusing component 340 and the second focusing component 350 are both coaxially arranged with the eyepiece assembly 200. Such an arrangement facilitates the layout of the first focusing component 340 and the second focusing component 350 in the fuselage assembly 100, and the two are coaxial with the eyepiece assembly 200 and sequentially arranged along the axial direction, which is convenient for user operation, such as being able to screw the two from the same side of the monocular handheld device. Specifically, the interval between the first focusing component 340 and the second focusing component 350 is not greater than the preset spacing. The two are arranged close to each other, which is convenient for the user to quickly realize the screwing operation of the two, further improving the convenience of operation.

[0069] In some embodiments, the outer circumferences of the first focusing component 340 and the second focusing component 350 are both provided with non-slip soft rubber pads. By providing the non-slip soft rubber pads, the friction acting on the knob is increased, so that even wearing gloves, a clear focusing feel can be achieved, further improving the user experience. The non-slip soft rubber pads can be made of materials such as silicone pads and rubber pads.

[0070] In some embodiments, a gain fill light 360 is further provided on the support body 310. By providing the gain fill light 360, the user's usage scenarios are further expanded. When the support body 310 includes a front flange 311, a rear flange 312, and a middle piece 313, the gain fill light 360 is provided at one end of the rear flange 312 where the first lens 320 and the second lens 330 are provided.

[0071] In some embodiments, see Figure 5 and Figure 6 The end of the support body 310 away from the fuselage assembly 100 is provided with a flexible protection ring 390. That is, the front end of the objective lens assembly 300 is provided with a flexible protection ring 390 to provide protection when the entire device accidentally falls. The flexible protection ring 390 can be made of plastic, silicone and other materials.

[0072] In some embodiments, see Fig.14 The body assembly 100 includes a bracket 120 and a shell 110 that is covered outside the bracket 120. The bracket 120 is connected to the support body 310, and the circuit board of the monocular handheld device is arranged on the bracket 120. By setting the bracket 120, the circuit board is arranged on the bracket 120. During assembly, after the bracket 120 is connected to the support body 310, the shell 110 is sleeved outside the bracket 120. In the case where the support body 310 includes a front flange 311, a rear flange 312 and an intermediate piece 313, the bracket 120 is connected to the rear flange 312. Compared with the circuit board being arranged on the shell 110, by setting the bracket 120 that is separate from the shell 110 and arranging the circuit board on the bracket 120, the internal structure is simple and compact, and it is convenient for the device to perform software debugging, and the later maintenance is simple. Specifically, the bracket 120 and the support body 310, as well as the shell 110 and the bracket 120, can be detachably connected, such as bolted, which is convenient for disassembly and assembly, so as to facilitate later maintenance.

[0073] In some embodiments, see Figure 1 and Figure 2A battery compartment 140 and a heat dissipation component 130 are respectively provided on opposite sides of the outer peripheral surface of the body component 100. Specifically, the heat dissipation component 130 is provided on the left side of the body component 100. For most right-handed users, when holding the device with their right hand, they can avoid the heat dissipation area, reduce the strange feeling caused by the heating of the product to people, and increase the comfort of holding. The heat dissipation component 130 includes but is not limited to a heat dissipation plate for dissipating the main chip. Accordingly, a battery compartment 140 is provided on the right side of the body component 100, and specifically, the battery compartment 140 is used for detachably installing a battery, that is, the monocular handheld device supports battery replacement to increase the battery life.

[0074] Specifically, the heat dissipation component 130 is integrated with an external Type C interface for charging and data transmission. A universal 1 / 4 interface 150 can be set at the center of gravity of the bottom of the shell 110 to facilitate later expansion, such as supporting the use with a tripod and a grip. The upper part of the body assembly 100 can be specifically provided with a rotary encoder assembly 180, a power button 160 and a camera button 170, which are comfortable to operate and ergonomic. The overall structure has a regular appearance, which is convenient for long-term single-handed holding.

[0075] In some embodiments, at least the left side portion of the body assembly 100 is made of lightweight plastic material, and skin-friendly soft rubber material is provided in the holding area, specifically the upper and lower parts of the body assembly 100, to reduce the weight of the whole device.

[0076] In some embodiments, the first lens 320 is an infrared lens, and the second lens 330 is a low-light lens; or, the first lens 320 is a low-light lens, and the second lens 330 is an infrared lens. The low-light lens can be a starlight night vision lens. Figure 4 As shown, the support body 310 is provided with an infrared detection position 370 for installing an infrared detector, and / or a low illumination detection position 380 for installing a low illumination detector. The infrared detector and the low illumination detector can provide infrared detection and low illumination detection functions. In the case where the support body 310 includes a front flange 311, a rear flange 312 and a middle piece 313, the infrared detection position 370 and / or the low illumination detection position 380 can be arranged at the rear flange 312, specifically, the first lens 320 and the second lens 330 are arranged at one end of the rear flange 312, and the infrared detection position 370 and / or the low illumination detection position 380 are arranged at the other end of the rear flange 312.
