In addition, the rotating shaft between the rotating arm and the mirror bracket can adjust the damping, and the contact part is provided with a sealing ring, so that the dustproof and waterproof performance of the structure is ensured, and the structure is suitable for various working environments.

Description

Technical Field

[0001] The invention relates to the technical field of night vision devices, in particular to a rotating and flipping automatic power on and off structure of a night vision device. Background Art

[0002] The principle of night vision devices that rely on low-light-level night vision tubes is to receive light through an objective lens, and rely on low-light-level night vision image intensifier tubes to perform photoelectric conversion on starlight and produce an avalanche effect to amplify the existing light source to achieve the effect of low-light amplification. This type of product is now widely used in the military, police and outdoor fields for observation operations at night or in low-light environments. In this sub-segment, binocular and dual-objective night vision devices (referred to as binocular night vision devices) include two independent objective lenses and two independent eyepieces, and use two separate low-light-level image intensifier tubes respectively, so that they can have better visual effects and comprehensive performance such as visual distance, and are more widely used in special fields such as special operations, high-speed driving, and aircraft driving.

[0003] There are two main types of existing binocular night vision devices. One is a binocular night vision device with two lens barrels that are completely fixed and cannot be flipped sideways, and the other is a binocular night vision device with a structure similar to a telescope and a lens barrel that can be flipped sideways. The practicality of binocular dual-objective low-light night vision devices is limited due to the size, and in actual use, the design of the binoculars prevents users from using the other naked eye to observe in a normal light environment like using a single-objective night vision device. Binocular night vision devices with a lens barrel that can be flipped sideways can solve this problem, but existing binocular night vision devices with a lens barrel that can be flipped sideways generally continue to be powered on after the user flips the lens barrel sideways, because the general solution for the assembly and design of binocular night vision devices is to directly introduce the wiring harness into the lens barrel through the rotating shaft and directly connect it to the image intensifier. Users cannot turn off the image intensifier on one side alone. If they want to turn off the image intensifier, they can only turn off both image intensifiers at the same time through the main power switch.

[0004] In actual use, especially when binocular night vision goggles are used for special operations or law enforcement in low-light environments, since it is unclear whether the indoor or outdoor environment is dim or bright, combatants need to keep one side of the binocular night vision goggles that can be flipped sideways on their eyes and flip the other side up, so that one eye has the low-light vision of the night vision goggles and the other eye has the vision of natural light. However, the existing structure and scheme will result in that even if the single-sided or double-sided lens barrel can be flipped sideways individually or simultaneously, the flipped-up side of the lens barrel will continue to be powered; if the ambient light is too bright at this time, there is a risk of damage to the image intensifier tube. If the main power is turned off, the meaning of wearing night vision goggles will be completely lost, that is, both eyes will lose the ability to observe in low light. If you rush into the house and find that the light is dim at this time, turning on the power will delay the fighter and even cause casualties.

[0005] In actual use, flipping the binocular night vision goggles sideways to outside the eyes instead of folding them vertically to the top of the helmet also has many other advantages, such as more effectively reducing bumps, etc. However, the existing solution requires users to flip the night vision goggles sideways and then manually turn off the power. When the night vision goggles are needed, they must first turn on the power and then flip the goggles sideways, which will cause a lot of delays and seriously delay the fighter.

[0006] This means that the lens barrel can be flipped sideways, and the image intensifier in the lens barrel on that side is automatically powered off after the lens barrel is flipped out of the eye's field of view; the function of automatically powering on after the lens barrel is flipped down to the eye's field of view is very important.

[0007] An existing solution is an automatic power-on and power-off shaft structure invented by me through hard contact between contacts and metal contacts (patent numbers: ZL202020227194.X and ZL202010129207.4). This technical solution is very effective, but there is a possibility that the contacts will break after long-term use, causing the shaft power-on structure to fail. After long-term and multiple uses, this technical solution will also cause the protruding contacts to rub against the non-metallic parts in the shaft structure multiple times, causing the non-metallic parts to wear out. This will cause the contacts to automatically pop out at the worn part, and get stuck on the metal conductive structure when encountering the metal conductive structure. Summary of the invention

[0008] To this end, the present invention provides a rotating and flipping automatic power on and off structure for a night vision device to solve the above-mentioned problems in the prior art.

[0009] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rotating and flipping automatic power-on and power-off structure of a night vision goggles, comprising a frame, two rotating arms, two night vision goggles, two magnets and two Hall sensors, the two rotating arms are connected to both sides of the frame through a rotating shaft, the night vision goggles are installed at the lower part of the rotating arm, the Hall sensor is provided on the frame, the magnet is installed on the top of the rotating arm, and the magnet and the Hall sensor form a non-rigid contact structure to control the power on and off of the night vision goggles.

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

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

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

[0013] Furthermore, when the rotating arm drives the night vision goggles to rotate until the magnet enters the sector-shaped sensing range of the Hall sensor, the Hall sensor sends a signal to automatically power on the night vision goggles.

[0014] Furthermore, when the rotating arm drives the night vision goggles to rotate until the magnet leaves the sector-shaped sensing range of the Hall sensor, the Hall sensor sends a signal to automatically power off the night vision goggles.

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

[0016] Furthermore, sealing rings are provided at the contact parts between the rotating shaft, the mirror frame and the rotating arm to ensure that the rotating parts are dustproof and waterproof.

[0017] Compared with the prior art, it has the following beneficial effects:

[0018] 1. The rotating and rolling automatic power-on and power-off structure of the night vision device realizes the automatic power-on and power-off function of the binocular night vision device barrel during the sideways rolling process by introducing the non-rigid contact structure of the Hall sensor and the magnet. This innovative design not only retains the advantages of binocular night vision devices in special fields such as special operations and high-speed driving, but also significantly improves its practicality and flexibility, allowing combatants or users to switch observation modes more freely in complex light environments;

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

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

[0021] 4. The rotating and rolling automatic power-on and power-off structure of the night vision device adopts the non-rigid contact method between the Hall sensor and the magnet, compared with the automatic power-on and power-off structure realized by the hard contact between the contact and the metal contact piece, which avoids the failure problem caused by the breakage or wear of the contact after long-term use. This improvement not only improves the stability and reliability of the structure, but also reduces the difficulty and cost of maintenance;

[0022] 5. The rotating and flipping automatic power-on and power-off structure of the night vision device can realize the automatic power-on and power-off function of the night vision device barrel, so that the binocular night vision device can be used in more scenarios. Whether in harsh environments such as rainy days and dust, or in scenarios where the observation mode needs to be switched quickly, this technical solution can provide excellent performance and reliability.

[0041] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1

[0043] like Figures 1 to 6As shown, the rotating and rolling automatic power-on and power-off structure of the night vision device of the present invention is mainly composed of a frame 1, two rotating arms 2, two night vision goggles 3, two magnets 22 and two Hall sensors 111, wherein the two rotating arms 2 are correspondingly connected to the two sides of the frame 1 through a rotating shaft, the two night vision goggles 3 are correspondingly installed at the lower parts of the two rotating arms 2, and the two magnets 22 are embeddedly installed at the tops of the corresponding rotating arms 2. The frame 1 includes a mirror body 11, and the two Hall sensors 111 are symmetrically installed inside the mirror body 11. The magnets 22 and the Hall sensors 111 jointly form a non-rigid contact structure. Through the non-rigid contact structure, when any rotating arm 2 drives the corresponding night vision goggles 3 to deflect, the night vision goggles 3 can be powered on and off;

[0044] A reserved groove 21 is reserved at the top of the rotating arm 2, and the magnet 22 is fixed inside the reserved groove 21, so that the magnet 22 does not protrude from the top of the rotating arm 2, thereby not affecting the deflection of the rotating arm 2;

[0045] The rotating shaft connecting the frame 1 and the rotating arm 2 is a rotating shaft with adjustable damping size, and sealing rings are provided at the contact parts of the rotating shaft, the frame 1 and the rotating arm 2 to ensure that the frame 1, the rotating arm 2 and the rotating part of the rotating shaft always remain dustproof and waterproof, enriching the operating scenarios of the entire night vision device, such as use in humid environments such as rainy days and environments with a lot of sand and dust.

[0046] When this embodiment is used, in the feature that the Hall sensor 111 and the magnet 22 form a non-rigid contact structure together, the detection range of the Hall sensor 111 is a sector-shaped area, and the angle of the sector-shaped area is about 30°. When the power is turned on and off, the specific process is as follows:

[0047] When the night vision goggles 3 and the rotating arm 2 are rotated toward the eyes, that is, downward to a certain angle, the magnet 22 will enter the 30° fan-shaped sensing range of the Hall sensor 111. At this time, the Hall sensor 111 sends a signal to the circuit in the frame 1, so that the night vision goggles 3 on this side are automatically powered on. Similarly, when the night vision goggles 3 and the rotating arm 2 are rotated away from the eyes, that is, upward, once the magnet 22 is not in the 30° fan-shaped sensing range of the Hall sensor 111, the Hall sensor 111 will not be able to capture the magnetic field emitted by the magnet 22. At this time, the signal will be automatically transmitted to the circuit, so that the night vision goggles 3 on this side are automatically powered off, thereby realizing the power-on or power-off function of the night vision goggles 3 when in use or not in use.

The cap 125 with different lenses is selected for practical use, which improves the ability of the binocular night vision goggles to adapt to the environment, thereby ensuring that the fill light can stably and continuously play its lighting function. The outer end of the cap 125 protrudes from the handle 16, and the protruding part 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 realizes ingenious planning in space utilization, but also greatly improves the convenience and reliability of the use of the fill light in actual operation.

[0054] In addition, a reserved hole 121 and a reserved hole 122 are respectively reserved at the bottom of the front cover 12, and the fill light 123 and the photosensitive sensor 124 are correspondingly installed inside the reserved hole 121 and the reserved hole 122, that is, 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 caused by external factors.

[0055] A battery compartment 14 is also reserved inside the front cover 12, and the port of the battery compartment 14 is threadedly connected to the battery compartment cover 15, and the end of the battery compartment cover 15 is movably connected to the handle 16.
