Description

TECHNICAL FIELD

[0001] The utility model relates to night vision instrument technical field, concretely is the rotation side turn automatic on-off structure of night vision instrument. BACKGROUND

[0002] The night vision instrument relying on the night vision tube has the principle that the light source is received through the objective lens, the starlight is photoelectrically converted and avalanche effect amplification of the existing light source is generated to the micro light amplification effect, the product is widely used in the military police and outdoor field for observation operation in the night or micro light environment. In this subdivision field, binocular double objective lens night vision instrument (binocular night vision instrument) includes two independent objective lenses and two independent eyepieces, and two separate micro light image intensifiers are used, so that better visual effect and visual distance feeling and other comprehensive performance can be obtained, and the binocular night vision instrument is more widely used in special combat, high-speed driving, aircraft driving and other special fields.

[0003] The existing binocular night vision instrument mainly has two types, one is a binocular night vision instrument with two lens barrels that cannot be laterally turned over, and the other is a binocular night vision instrument that can laterally turn over the lens barrel and has a structure similar to a telescope. The binocular double objective lens micro light night vision instrument is limited in practicality due to the volume, and in actual use, the design of the binocular causes the user to be unable to observe the normal light environment with the other naked eye as in the use of the single objective lens night vision instrument. The binocular night vision instrument that can laterally turn over the lens barrel can solve this problem, but the existing binocular night vision instrument that can laterally turn over the lens barrel still continues to be powered after the user laterally turns over the lens barrel, because the general solution of the binocular night vision instrument assembly and design is to directly introduce the wire harness into the lens barrel through the rotating shaft and connect the image intensifier. The user cannot independently turn off the image intensifier on one side, and if the image intensifier is to be turned off, the two image intensifiers can only be turned off at the same time through the total power switch.

[0004] In actual use, especially when the binocular night vision instrument is used in special combat or dark light environment law enforcement, since it is not clear whether the indoor or outdoor environment is dim or bright, the combat personnel need to keep one side of the binocular night vision instrument that can laterally turn over the lens barrel at the eye, and the other side is turned over, so that one eye has the micro light vision of the night vision instrument, and the other eye has the vision of natural light. The existing structure and solution will cause the side of the lens barrel that is turned over to continue to be powered even if the single or double lens barrel can be laterally turned over independently or simultaneously; if the ambient light is too bright at this time, the image intensifier will be at risk of damage. If the total power supply is turned off, the significance of wearing the night vision instrument will be completely lost, that is, the micro light observation ability of both eyes is lost, and if the light is dim when entering the house at this time, the power is turned on again, which will delay the battle and even cause the personnel to be sacrificed.

[0005] In actual use, there are many other advantages in laterally turning the binocular night vision device away from the eyes instead of longitudinally folding the night vision device to the top of the helmet, such as more effective reduction of bumps and the like. However, the existing scheme causes the user to manually turn off the power after laterally turning the mirror barrel of the night vision device, and to manually turn on the power before laterally turning down the mirror barrel when the night vision device needs to be used, which causes a lot of time to be wasted and seriously delays the battle.

[0006] This means that the side mirror barrel can be laterally turned, and the image intensifier in the side mirror barrel is automatically powered off after the mirror barrel is turned away from the field of view of the eyes; the function of automatically powering on after the mirror barrel is turned down to the field of view of the eyes is very important.

[0007] One of the existing schemes is an automatic power-on and power-off rotating shaft structure (Patent Nos. ZL202020227194.X and ZL202010129207.4) of the present utility model through hard contact of a contact and a metal contact piece, which is very effective, but there is a possibility that the contact will break after long-term use, causing the rotating shaft power-on structure to fail. After long-term use, the convex contact and the non-metallic part in the rotating shaft structure will be rubbed many times, causing the non-metallic part to be worn out, which will cause the contact to automatically pop out at the worn-out part and be stuck on the metal conductive structure when it encounters the metal conductive structure. Utility model content

[0008] Therefore, the utility model provides a rotating lateral turning automatic power-on and power-off structure of a night vision device to solve the above problems in the prior art.

[0009] In order to achieve the above purpose, the utility model provides the following technical scheme: a rotating lateral turning automatic power-on and power-off structure of a night vision device, comprising a mirror frame, two rotating arms, two night vision mirrors, two magnets and two Hall sensors, the two rotating arms are connected on both sides of the mirror frame through a rotating shaft, the night vision mirrors are installed at the lower part of the rotating arms, the Hall sensors are arranged on the mirror frame, the magnets are installed at the top of the rotating arms, and the magnets and the Hall sensors form a non-hard contact structure to control the power-on and power-off of the night vision mirrors.

[0010] Further, the mirror frame comprises a mirror body, and the two Hall sensors are symmetrically installed inside the mirror body.

[0011] Further, the top of the rotating arm is reserved with a reserved groove, and the magnet is fixed inside the reserved groove.

[0012] Further, the detection range of the Hall sensor is a fan-shaped area, and the angle of the fan-shaped area is 30°.

[0013] Further, when the rotating arm drives the night vision mirror to rotate to the fan-shaped sensing range of the magnet entering the Hall sensor, the Hall sensor sends a signal to automatically power on the night vision mirror.

[0014] Further, when the rotating arm drives the night vision mirror to rotate to the sector sensing range where the magnet is away from the Hall sensor, the Hall sensor sends a signal to automatically power off the night vision mirror.

[0015] Further, the rotating shaft connecting the mirror frame and the rotating arm is a rotating shaft with adjustable damping size.

[0016] Further, the contact parts of the rotating shaft, the mirror frame and the rotating arm are all sleeved with sealing rings to ensure dust and water prevention at the rotating part.

[0017] Compared with the prior art, the following beneficial effects are achieved:

[0018] 1. The rotation and side turning automatic on-off power structure of the night vision device realizes the automatic on-off power function of the binocular night vision device barrel during the side turning process through the introduction of the non-hard contact structure of the Hall sensor and the magnet. This innovative design not only retains the advantages of the binocular night vision device in special operations, high-speed driving and other special fields, but also significantly improves the practicality and flexibility, enabling combat personnel or users to switch observation modes more freely in complex light environments;

[0019] 2. The rotation and side turning automatic on-off power structure of the night vision device allows the user to use the night vision device on one side while maintaining the natural light vision of the other eye, thereby improving combat efficiency and safety. In addition, the automatic on-off power function also avoids time delay due to manual operation, ensuring that combat personnel can respond quickly;

[0020] 3. The rotation and side turning automatic on-off power structure of the night vision device, compared with the method of folding the night vision device longitudinally to the top of the helmet, can effectively reduce the risk of accidental damage such as bumping;

[0021] 4. The rotation and side turning automatic on-off power structure of the night vision device, compared with the automatic on-off power structure realized by hard contact of the contact and the metal contact, adopts the non-hard contact mode of the Hall sensor and the magnet, avoiding the failure problem caused by contact fracture or wear after long-term use. This improvement not only improves the stability and reliability of the structure, but also reduces the maintenance difficulty and cost;

[0022] 5. The rotation and side turning automatic on-off power structure of the night vision device realizes the automatic on-off power function of the night vision device barrel, enabling the binocular night vision device to be applied in more scenarios. Whether in rainy, dusty and other harsh environments, or in scenarios where quick switching of observation modes is required, this technical solution can provide excellent performance and reliability.

DETAILED DESCRIPTION

[0041] The embodiments of the utility model will be described below by specific examples, and the person skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. Obviously, the described embodiments are part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0042] Embodiment 1

[0043] As Figures 1 to 6The utility model discloses a rotation side -turn automatic on -off electricity structure of night vision instrument, mainly by mirror frame 1, two rotating arms 2, two night vision mirrors 3, two magnets 22 and two hall inductors 111 are formed, wherein, two rotating arms 2 are connected in the both sides of mirror frame 1 through the pivot correspondingly, two night vision mirrors 3 are installed in the lower part of two rotating arms 2 correspondingly, two magnets 22 are inlayed in the top of corresponding rotating arm 2, mirror frame 1 includes mirror body 11, two hall inductors 111 are installed in the inside of mirror body 11 symmetrically, magnet 22 and hall inductor 111 form non -hard contact structure together, through non -hard contact structure, when any one rotating arm 2 drives corresponding night vision mirror 3 to deflect, can achieve the power -off and power -on of this night vision mirror 3,

[0044] The top of rotating arm 2 is reserved to set up reserved groove 21, and the magnet 22 is fixed in the inside of reserved groove 21, so that the magnet 22 is not conspicuous on the top of rotating arm 2, and then will not affect the deflection of rotating arm 2.

[0045] The pivot connecting mirror frame 1 and rotating arm 2 is the pivot of adjustable damping size, and the contact parts of the pivot and mirror frame 1 and rotating arm 2 are all sleeved with sealing rings, to ensure that the rotating parts of mirror frame 1, rotating arm 2 and pivot always keep dustproof and waterproof state, and the operation scene of the whole night vision instrument is enriched, for example, in rainy day and humid environment and in the environment with more dust.

[0046] In the use of this embodiment, in the feature that hall inductor 111 and magnet 22 form non -hard contact structure together, the detection range of hall inductor 111 is a sector area, and the angle of the sector area is about 30 °, and the specific process when realizing power -on and power -off is as follows:

[0047] When the whole of night vision mirror 3 and rotating arm 2 rotates to the eye, that is, rotates downward to a certain angle, the magnet 22 will enter the 30 ° sector sensing range of hall inductor 111, at this time, hall inductor 111 sends a signal to the circuit in mirror frame 1, so that the night vision mirror 3 on this side is automatically powered on, and for the same reason, when the whole of night vision mirror 3 and rotating arm 2 rotates away from the eye, that is, rotates upward, once the magnet 22 is not in the 30 ° sector sensing range of hall inductor 111, hall inductor 111 will not capture the magnetic field emitted by magnet 22, at this time, the signal will be automatically transmitted to the circuit, so that the night vision mirror 3 on this side is automatically powered off, thereby realizing the power -on or power -off function of night vision mirror 3 in use or non -use state.

[0048] Embodiment 2

[0049] As Figures 7 to 8As shown, the rotating and tilting automatic power-on / off structure of the night vision device of this utility model consists of a lens frame 1 mainly composed of a lens body 11, a front cover 12, and a rear cover 13. The front cover 12 and the rear cover 13 are installed on both sides of the lens body 11 by bolts. That is to say, the front cover 12 and the rear cover 13 can protect the lens body 11 when installed, and can be replaced when disassembled. In addition, the battery compartment 14 is fixedly installed inside the front cover 12. The installation direction of the battery compartment 14 is perpendicular to the front cover 12, and the tail end of the battery compartment 14 extends into the interior of the lens body 11. By rationally arranging the position of the battery compartment 14, the volume of the entire binocular night vision device is greatly reduced, and the space occupied by the battery compartment 14 itself is also reduced.

[0050] The mirror body 11 has a cavity inside, the end of the battery compartment 14 is located inside the cavity, the port of the battery compartment 14 is connected to the battery compartment cover 15 by threads, and the outside of the battery compartment cover 15 is rotatably connected to the handle 16.

[0051] The bolts are divided into two types: long screws 18 and short screws 17. The lens body 11 and the front cover 12 are connected and fixed by several short screws 17, and the lens body 11 and the rear cover 13 are connected and fixed by several long screws 18.

[0052] Example 3

[0053] like Figure 1 , Figures 9 to 10 As shown, the rotating and tilting automatic power-on / off structure of this utility model's night vision device mainly consists of a front cover 12, a supplementary light 123, a photosensor 124, and a cap 125. The supplementary light 123 and the photosensor 124 are both embedded in the bottom of the front cover 12. A cap 125, threadedly connected to the front cover 12, is provided outside the supplementary light 123. A lens 126 is installed inside the cap 125 at the end opposite to the front cover 12. The lens 126 can be a convex or concave lens, and can adjust its operation according to different light sources and scenes. Choosing caps 125 with different lenses for practical use improves the binocular night vision goggles' ability to adapt to the environment, thereby ensuring that the fill light can stably and continuously perform its lighting function. The outer end of the cap 125 protrudes from the handle 16, and the protrusion can effectively prevent the handle of the battery compartment cover from blocking the light emitted by the fill light 123 when moving. This protruding layout not only achieves clever planning in terms of space utilization, but also greatly improves the convenience and reliability of the fill light in actual operation.

[0054] In addition, the bottom of the front cover 12 has reserved holes 121 and 122 respectively. The fill light 123 and the photosensitive sensor 124 are installed inside the reserved holes 121 and 122 respectively. In other words, the fill light 123 and the photosensitive sensor 124 can be hidden in the front cover 12 to avoid damage to the fill light 123 and the photosensitive sensor 124 due to collisions or other external factors.

[0055] The front cover 12 also has a reserved battery compartment 14 inside. The port of the battery compartment 14 is threaded to the battery compartment cover 15, and the end of the battery compartment cover 15 is movably connected to the handle 16. At least one night vision goggle 3 is connected to the lower part of the front cover 12. One end of the night vision goggle 3 is set as the objective lens 31, and the other end is set as the eyepiece 32. It should be noted that the supplementary light 123, the photosensor 124, and the cap 125 are all set on the same side as the objective lens 31, so as to facilitate supplementary lighting of the external environment and perception of ambient light.

A multi-functional reserved hole 44 is reserved inside the main body 41. The multi-functional reserved hole 44 is connected to the weight reduction first groove 42. In addition to its weight reduction function, the multi-functional reserved hole 44 can also serve as a... The inflation clearance hole is set at the top of the binocular night vision goggle, which is a through hole for filling with nitrogen. The opening of the multi-functional reserved hole 44 allows the nitrogen through hole to be exposed, which is convenient for filling with nitrogen. This improves the practicality and flexibility of the connector and meets the needs of different application scenarios. Several bolt mounting positions are reserved inside the main body 41 and around the multi-functional reserved hole 44. The end of the main body 41 is symmetrically opened with a weight reduction first slope 48, and the bottom of both sides of the main body 41 is opened with a weight reduction second slope 49. The opening angle of the weight reduction first slope 48 and the weight reduction second slope 49 is set to 45°.

This not only reduces the burden on the wearer, but also improves the comfort of wearing for a long time and avoids neck and head fatigue caused by excessive weight.

[0059] The bolt mounting position is composed of a stepped groove 45 reserved and opened at the bottom end of the first weight-reducing groove 42, a protruding portion 46 integrally connected at the bottom of the main body portion 41, and a jack 47 jointly opened by the main body portion 41 and the stepped groove 45, wherein the stepped groove 45 and the jack 47 are communicated, the stepped groove 45 can hide the head of the bolt therein, and the installation of the connecting piece on the binocular night vision mirror can be completed by inserting the bolt into the bolt mounting position.
