Description

Technical Field

[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.

DETAILED DESCRIPTION

[0043] The embodiment of the utility model discloses a monocular handheld device to expand the usage scenarios of multi-light device users.

[0044] 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.

[0045] In one embodiment, see Figure 1-Figure 6 The monocular handheld device provided by the utility model 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, and includes a supporting body 310, a first lens 320, a second lens 330 and a gain fill light 360. The supporting body 310 is arranged on the fuselage assembly 100, and the first lens 320, the second lens 330 and the gain fill light 360 are all arranged on the supporting body 310, and the optical axes of the first lens 320 and the second lens 330 are parallel; wherein the first lens 320 is an infrared lens, and the second lens 330 is a low illumination lens; or the first lens 320 is a low illumination lens, and the second lens 330 is an infrared lens. The first lens 320 and the second lens 330 can realize multi-light fusion.

[0046] Using the monocular handheld device provided by the utility model, the objective lens assembly 300 includes a first lens 320, a second lens 330 and a gain fill light 360, and all three are arranged on the supporting body 310. The optical axes of the first lens 320 and the second lens 330 are parallel, so that multi-light fusion of low illumination and infrared can be achieved. By setting the gain fill light 360, clear imaging can be achieved even in a purely dark environment, thereby expanding the user usage scenarios of the monocular handheld device.

[0047] In some embodiments, the low illumination lens is a starlight night vision lens or a low light level night vision lens, so as to better meet the imaging requirements in a dark environment.

[0048] In some embodiments, the first lens 320 and the second lens 330 are slidably disposed on the support body 310 along their respective optical axis directions. The first lens 320 and the second lens 330 are slidably disposed on the support body 310 along their respective optical axis directions, and the first lens 320 and the second lens 330 can move forward and backward along the corresponding optical axis, respectively, to 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 separate focal length adjustment for clear imaging.

[0049] In some embodiments, the monocular handheld device further includes a first adjustment ring and a second adjustment ring arranged in sequence along the axial direction, the first adjustment ring and the second adjustment ring are rotatably arranged on the outer periphery of the support body 310, the first adjustment ring is used to drive the first lens 320 to move along its optical axis, and the second adjustment ring is used to drive the second lens 330 to move along its optical axis. Specifically, the first adjustment ring and the second adjustment ring are coaxial and are sequentially sleeved outside the first lens 320 and the second lens 330 along the axial direction, and the first adjustment ring and the second adjustment ring can rotate around the axial direction respectively. It should be noted that the first adjustment ring and the second adjustment ring can be in the shape of a closed annular ring or a partial annular ring, that is, an unclosed structure. When the first adjustment ring rotates around the axial direction, the first lens 320 can be driven 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, so as to achieve the single focus of the first lens 320; when the second adjustment ring rotates around the axial direction, the second lens 330 can be driven 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, so as to achieve the single focus of the second lens 330.

[0050] In some embodiments, the first adjustment ring or the second adjustment ring located on the outside protrudes from the first lens 320, the second lens 330 and the gain fill light 360 in the axial direction. Taking the first adjustment ring located on the outside as an example, that is, the first adjustment ring is axially located on the outside of the monocular handheld device relative to the second adjustment ring, and the first lens 320, the second lens 330 and the gain fill light 360 are all sleeved in the first adjustment ring, rather than protruding from the lens barrel respectively. The three are all arranged in the same large lens barrel, the appearance is neater and more beautiful, and the structure is simple and compact. In other embodiments, the first lens 320, the second lens 330 and the gain fill light 360 can also protrude from the first adjustment ring or the second adjustment ring located on the outside in the axial direction or be flush with each other as needed.

[0051] In some embodiments, the gain fill light 360 includes an LED fill light or a laser fill light. Ordinary LED fill lights have low costs, and because their light-emitting principles are different from those of lasers, they can be used in areas or environments that have regulatory requirements for laser product safety standards. Laser fill lights are small in size and have a long range. Under the same power, laser fill lights can provide better fill light effects.

[0052] In some embodiments, the gain fill light 360 is a fixed-focus fill light or a zoom fill light. When the gain fill light 360 is a fixed-focus fill light, it can be fixedly connected to the support body 310, such as being threadedly connected to the rear flange 312. As set above, the installation is simple and the cost is low. The gain fill light 360 type is more suitable for LED lamp beads.

[0053] In some embodiments, the gain fill light 360 is a zoom fill light. Figure 7-10 The zoom fill light includes a fill light housing 361, a fill light adjustment member 362, a lamp body 363 and a lens 364. The fill light housing 361 is disposed on the supporting body 310, and can be specifically disposed on the rear flange 312. The lens 364 is disposed at one end of the fill light housing 361, the lamp body 363 is disposed on the fill light adjustment member 362, and the fill light adjustment member 362 is slidably disposed at the other end of the fill light housing 361 along the axial direction to adjust the focal length of the lamp body 363. When the zoom fill light needs to be adjusted, the fill light adjustment member 362 moves along the axial direction, thereby changing the distance between the lamp body 363 and the lens 364, and realizing zooming to better adapt to different usage environments. Specifically, the lamp body 363 is disposed on a substrate 365, and the substrate 365 is disposed on the fill light adjustment member 362.

[0054] In some embodiments, the first adjustment ring or the second adjustment ring that cooperates with the low-light lens cooperates with the fill light adjustment member 362, and is used to drive the low-light lens and the fill light adjustment member 362 to slide axially. Taking the second lens 330 as a low-light lens as an example, the second adjustment ring that cooperates with it cooperates with the fill light adjustment member 362, and is used to drive the low-light lens and the fill light adjustment member 362 to slide axially. Then the zoom fill light can adjust the distance between the lamp body 363 and the lens 364 by rotating the second adjustment ring, and the adjustment method is similar to the focus adjustment of the second lens 330. As set above, when using the low-light mode to look at nearby and distant targets, the effect of the fill light can be exerted at all times. This mode is particularly suitable for laser fill lights. Since the laser fill light has a long range and high brightness, when the focus of the fill light is set to long-distance observation, the focusing effect is good, and it is easy to produce overexposure when looking at nearby targets, affecting observation. Specifically, the fill light adjustment member 362 is provided with an external thread, which cooperates with the internal thread of the second adjustment ring. When the second adjustment ring is rotated, the fill light adjustment member 362 is driven to move along the axial direction, and the distance between the lamp body 363 and the lens 364 is changed to achieve zooming, and the low-light lens is focused at the same time. In order to make the focusing distance of the zoom fill light match the observation distance of the lens, it is necessary to control the fill light to illuminate the farthest and closest points of night vision when observing the farthest or closest point during installation.

[0055] In some implementations, a fill light position for installing the gain fill light 360 is provided on the support body 310. By setting the fill light position, the gain fill light is easily installed and its installation position is accurate. The specific position of the fill light position on the support body 310 can be set according to the internal space of the monocular handheld device, and is not specifically limited here.

[0056] In some embodiments, the monocular handheld device further includes a laser ranging module and / or a laser indication module, and the fill light position is used to detachably install one of the gain fill light 360, the laser ranging module and the laser indication module. Then, according to the use needs, the user can selectively install one of the gain fill light 360, the laser ranging module and the laser indication module in the fill light position. When the shooting requirements are different and need to be replaced, the gain fill light 360, the laser ranging module or the laser indication module installed on the fill light position can be removed and replaced accordingly. The above arrangement makes the use scenarios of the monocular handheld device more diverse. The specific structure of the laser ranging module and the laser indication module can refer to the conventional components that can realize laser ranging and the components that can emit laser to provide indication.

[0057] In some embodiments, see Figure 1-Figure 6The monocular handheld device provided by the utility model comprises a body assembly 100, an eyepiece assembly 200 and an objective lens assembly 300. Among them, the objective lens assembly 300 is arranged at the front end of the body assembly 100, and the objective lens assembly 300 comprises 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 on the body assembly 100, and is used to install the first lens 320, the second lens 330, the first focusing component 340 and the second focusing component 350, and its specific structure is set according to the installation needs. The first lens 320 and the second lens 330 are 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 detector target surface, 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 an infrared lens and a low-light lens, such as a combination of an infrared lens and a starlight night vision lens. The first focusing component 340 and the second focusing component 350 are respectively rotatably arranged on the support body 310 and are restricted from axial movement by the support body 310, that is, the first focusing component 340 and the second focusing component 350 can both rotate relative to the support 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 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 applicable. In addition, the rotation axis of the first focusing component 340 is coaxial with the rotation axis of the second focusing component 350. It should be noted that the rotation axis of the first focusing component 340 refers to the rotation axis of its rotation relative to the support body 310, and the corresponding rotation axis of the second focusing component 350 refers to the rotation axis of its rotation relative to the support 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.

[0058] In the monocular handheld device provided by the utility model, 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 the first lens 320 and the second lens 330 can be driven to move forward and backward by screwing the first focusing component 340 and the second focusing component 350, and the distance from the mirror surface of the first lens 320 and the second lens 330 to the target surface of the detector is changed to achieve clear imaging, that is, the monocular handheld device can achieve the single focal length adjustment of a single lens. And the rotating shafts 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.

[0059] In some embodiments, see Fig.11 and Fig.12 , 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.

[0060] In some embodiments, see Fig.13 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.

[0061] 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.

[0062] 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.

[0063] In some embodiments, see Figure 5 and Figure 6The support body 310 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 is 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 sandwiched between the front flange 311 and the middle piece 313, and the second focusing component 350 is sandwiched 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 by screw connection, so as to play a supporting role and facilitate disassembly and assembly. The front flange 311 and the rear flange 312 can also be detachably connected to the middle piece 313, such as by screw connection. Through the connection between 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, through the connection between 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 process does not interfere with each other. And 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, and improve the dual-light fusion effect of the product.
