Description

Technical Field

[0001] The invention relates to the technical field of night vision goggles, in particular to a binocular night vision goggles light-filling structure. Background Art

[0002] Binocular night vision goggles have become an indispensable tool for observation and monitoring at night or in low-light conditions. Although traditional binocular night vision goggles can provide basic night vision functions, they still have many deficiencies in fill light and light perception. For example, traditional night vision goggles often lack efficient fill light structures, resulting in a significant reduction in observation effects in extremely low-light environments. At the same time, due to the unreasonable design and installation position of fill lights and photosensitive sensors, they are easily disturbed and damaged by external factors, thus affecting their stability and service life.

[0003] In order to solve the above problems, various binocular night vision goggles fill light structures have appeared in the prior art. However, these fill light structures still have some defects in design. For example, some fill light lamps do not have a suitable shielding structure on the outside, resulting in the handle of the battery compartment cover easily blocking the light emitted by the fill light during movement or use, thereby affecting the lighting effect;

[0004] In addition, in the actual use of night vision goggles, especially in some military missions that require the highest degree of concealment, in order to prevent the enemy who is also wearing night vision goggles from observing the invisible light fill light of our night vision goggles, the user is usually prohibited from turning on any visible or invisible light fill light. In the actual use of night vision goggles, it is inevitable that the fill light may be turned on by mistake, which may lead to mission failure or even casualties. Summary of the invention

[0005] To this end, the present invention provides a binocular night vision goggle fill light structure to solve the above-mentioned problems in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a binocular night vision goggle fill light structure, comprising a front cover, a fill light and a light-sensitive sensor are embedded in the bottom of the front cover, a cap is provided on the outside of the fill light and is threadedly connected to the front cover, and a lens is installed inside the end of the cap away from the front cover.

[0007] Furthermore, the lens is a convex lens or a concave lens, and a cap with different lenses can be selected according to different light sources and scenes.

[0008] Furthermore, the outer end of the cap protrudes from the handle to prevent the handle from blocking the light emitted by the fill light when moving.

[0009] Furthermore, a first reserved hole for installing a fill light and a second reserved hole for installing a photosensor are respectively reserved at the bottom of the front cover.

[0010] Furthermore, a battery compartment is reserved inside the front cover, a port of the battery compartment is threadedly connected to a battery compartment cover, and an end of the battery compartment cover is movably connected to a handle.

[0011] Furthermore, the exterior of the cap can latch onto a physical sunshade (the physical sunshade is not shown in the figure) to block the light emitted by the fill light.

[0012] Furthermore, the lower part of the front cover is connected to at least one night vision goggles, one end of the night vision goggles is set as an objective lens, the other end is set as an eyepiece, and the fill light, photosensor and cap are all set on the same side as the objective lens.

[0013] Compared with the prior art, it has the following beneficial effects:

[0014] The fill light structure of the binocular night vision goggles effectively prevents the battery compartment cover handle from blocking the fill light. At the same time, a replaceable lens is installed inside the cap, and different lenses are selected according to different light sources and scenes, further improving the binocular night vision goggles' ability to adapt to the environment. In addition, the fill light and photosensitive sensor are both embedded in the bottom of the frame, and suitable installation holes are reserved to avoid damage caused by external factors. These improvement measures not only improve the practicality and convenience of binocular night vision goggles, but also provide strong support for their application in complex environments;

[0015] In addition, the fill light structure can be installed with a physical hood with a tenon, which physically blocks the fill light components and completely solves and eliminates such problems. Once the user needs to use the fill light, he only needs to take off the physical hood on the structure to continue using the fill light, which is efficient and convenient.

[0034] 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.

[0035] Example 1

[0036] like Figures 1 to 6 As shown, a binocular night vision goggle fill light structure 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 off and powered on;

[0037] 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;

[0038] 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.

[0039] 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:

[0040] 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.
