TECHNICAL FIELD
[0001] The utility model relates to night vision instrument technical field, concretely is a binocular night vision mirror light supplementing structure. BACKGROUND
[0002] When observing and monitoring at night or under low light conditions, binocular night vision mirrors become indispensable tools. Although traditional binocular night vision mirrors can provide basic night vision functions, they still have many deficiencies in light supplementing and light perception. For example, traditional night vision mirrors often lack efficient light supplementing structures, resulting in a significant reduction in observation effectiveness in extremely low light environments. At the same time, due to the unreasonable design and installation position of the light supplementing lamp and the photosensitive sensor, they are easily disturbed and damaged by external factors, thereby affecting their stability and service life.
[0003] To solve the above problems, various binocular night vision mirror light supplementing structures have appeared in the prior art. However, these light supplementing structures still have some defects in design. For example, some light supplementing lamps do not have suitable shielding structures on the outside, which causes the handle of the battery compartment cover to easily block the light emitted by the light supplementing lamp during movement or use, thereby affecting the lighting effect.
[0004] In addition, during the actual use of night vision instruments, especially in some military tasks that require the highest concealment, in order to prevent the enemy who also wears night vision instruments from observing the invisible light supplementing lamp of our night vision instruments, the user is usually prohibited from turning on any visible or invisible light supplementing lamp. However, during the actual use of night vision instruments, it is inevitable that the light supplementing lamp may be accidentally turned on, which may lead to task failure or even personnel casualties. INVENTION CONTENTS
[0005] Therefore, the utility model provides a binocular night vision mirror light supplementing structure to solve the above problems in the prior art.

[0007] Further, the lens is a convex lens or a concave lens, and the cap with different lenses can be selected according to different light sources and scenes.
[0008] Further, the outer end of the cap protrudes from the handle to prevent the handle from blocking the light emitted by the light supplementing lamp when moving.
[0009] Further, the bottom of the front cover is respectively reserved with a reserved hole one for installing the light supplementing lamp and a reserved hole two for installing the photosensitive sensor.
[0010] Further, the inside of the front cover is also reserved to be provided with a battery compartment, and the port of the battery compartment is threadedly connected with a battery compartment cover, and the end of the battery compartment cover is movably connected with a handle.

[0012] Further, the lower part of the front cover is connected with at least one night vision mirror, one end of the night vision mirror is provided with an objective lens, and the other end is provided with an eyepiece, and the light supplement lamp, the photosensitive sensor and the cap are all arranged on the same side as the objective lens.
[0013] Compared with the prior art, the following beneficial effects are achieved:
[0014] The light supplement structure of the binocular night vision mirror effectively prevents the handle of the battery compartment cover from blocking the light of the light supplement lamp. Meanwhile, the replaceable lens is also installed in the cap, different lenses can be selected according to different light sources and scenes, and the environmental adaptability of the binocular night vision mirror is further improved. In addition, the light supplement lamp and the photosensitive sensor are both embeddedly installed at the bottom of the frame, and appropriate mounting hole positions are reserved, so that damage caused by external factors is avoided. These improvement measures not only improve the practicability and convenience of the binocular night vision mirror, but also provide strong support for the application of the binocular night vision mirror in complex environments.

[0034] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

The two rotating arms 2 are connected to the two sides of the frame 1 via rotating shafts. The two night vision goggles 3 are installed at the lower part of the two rotating arms 2. The two magnets 22 are embedded in the top of the corresponding rotating arms 2. The frame 1 includes a lens body 11. The two Hall sensors 111 are symmetrically installed inside the lens body 11. The magnets 22 and the Hall sensors 111 together form a non-rigid contact structure. Through the non-rigid contact structure, when any rotating arm 2 drives the corresponding night vision goggle 3 to deflect, the power supply to the night vision goggle 3 can be turned off and on.
[0037] A reserved slot 21 is provided at the top of the rotating arm 2, and the magnet 22 is fixed inside the reserved slot 21 so that the magnet 22 does not protrude from the top of the rotating arm 2, thus not affecting the deflection of the rotating arm 2.

[0039] In the embodiment, the detection range of the Hall inductor 111 is a sector area with an angle of about 30° when the Hall inductor 111 and the magnet 22 jointly form a non-hard contact structure.
[0040] When the whole night vision mirror 3 and the rotating arm 2 rotate towards the eyes, that is, rotate downwards to a certain angle, the magnet 22 enters the 30° sector sensing range of the Hall inductor 111, at this time, the Hall inductor 111 sends a signal to the circuit in the frame 1, so that the night vision mirror 3 on this side is automatically powered on. Similarly, when the whole night vision mirror 3 and the rotating arm 2 rotate away from the eyes, that is, rotate upwards, once the magnet 22 is not in the 30° sector sensing range of the Hall inductor 111, the Hall inductor 111 cannot capture the magnetic field emitted by the magnet 22, at this time, the signal is 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 the night vision mirror 3 in the use or non-use state.
