Abstract
Description
Technical Field
[0001] This utility model relates to the field of night vision technology, and in particular to a night vision device with integrated infrared illumination. Background Technology
[0002] Night vision devices are optoelectronic imaging devices used to observe targets at night or in low-light environments. They typically convert invisible light signals into visible images by amplifying weak light (such as starlight or moonlight) or by using infrared detection technology, helping users achieve clear observation in the dark. Night vision devices generally consist of an objective lens, an imaging module, and an eyepiece, and can be classified as low-light type, infrared thermal imaging type, or fusion type devices. They are an important tool for performing nighttime missions.
[0003] In existing technologies, lens caps for night vision devices mostly adopt magnetic or snap-on structures, which are fitted around the outer ring of the lens of the night vision device to cover and protect the lens when not in use. However, when the user removes the lens cap to prepare to use the night vision device, the lens is exposed. If the user accidentally drops the night vision device during operation due to a slip or a sudden situation and it collides with the ground, the lens is very likely to be damaged by impact, resulting in scratches, breakage, or misalignment. Summary of the Invention
[0004] The purpose of this invention is to address the problem that existing night vision device lens caps mostly use magnetic or snap-on structures, which are fitted around the outer ring of the lens to cover and protect the lens when not in use. However, when the user removes the lens cap to use the night vision device, the lens is exposed. If the user accidentally drops the night vision device during operation due to a slip or a sudden situation and it collides with the ground, the lens is easily damaged by impact, resulting in scratches, breakage, or misalignment. Therefore, this invention proposes a night vision device with integrated infrared illumination.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A night vision device with integrated infrared illumination includes a night vision device body and a lens cover. An LED red light ring is fixedly installed on the outer wall of the lens of the night vision device body to provide illumination for the lens. A protective box is fixedly installed on the side of the night vision device body near the lens. A mounting lever is fixedly installed on the side of the lens cover. Horizontal sliding grooves are opened on the sides of the two protective boxes, and the mounting lever extends into the horizontal sliding grooves. A common drive component is installed inside the protective box, which drives the two lens covers to synchronously open or close the lens.
[0007] Optionally, the common drive assembly includes a first push rod, a second push rod, and a common block. The common block has a mounting groove on its side. One side of the mounting groove is rotatably connected to one end of the second push rod, and the other end of the second push rod is rotatably connected to one of the mounting rod sides.
[0008] Optionally, the common block is rotatably connected to the side of the mounting groove with a first push rod, the other end of the first push rod is rotatably disposed on the side of another mounting folding rod, and a reset guide assembly is provided on the side of the common block.
[0009] Optionally, the reset guide assembly includes a U-shaped rod, a vertical column, a vertical spring, and a common rod. The common rod is fixedly installed on the inner wall of the protective box. The common rod is movably inserted into the vertical column in the vertical direction, and a U-shaped rod is fixedly installed on the top of the vertical column.
[0010] Optionally, one end of the U-shaped rod is fixedly disposed on the side of the common block, the bottom of the U-shaped rod is fixedly connected to one end of the vertical spring, and the other end of the vertical spring is fixedly disposed on the top of the common rod.
[0011] Optionally, the protective box has an extended edge fixedly provided on the top side away from the lens, and the common block has a pressing and folding rod fixedly provided on its top.
[0012] Optionally, the pressing and holding folding rod includes a horizontal section and a vertical section, and there is a gap between the horizontal section of the pressing and holding folding rod and the top of the extension edge.
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] 1. This night vision device has a protective case on the front side of its housing. The lens cap of the night vision device is inserted into the inner cavity of the protective case via a hinged rod. Inside the protective case is a common drive component. When the user holds and uses the night vision device, the gripping action will force the common drive component to open the lens. If the user accidentally releases the device, the common drive component will lose its force control and the reset elastic structure will quickly close the lens cap, effectively covering the lens and preventing it from directly contacting the ground, thus effectively protecting the lens.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5 A night vision device with integrated infrared illumination includes a night vision device body 3 and a lens cover 5. The specific structure of the night vision device body 3 is disclosed in patent publication number CN219285503U. The specific structure of the night vision device body 3 is prior art and therefore is not disclosed in this application.
[0023] To improve the imaging brightness and clarity of the night vision device and ensure target visibility, an LED red light ring 1 is fixedly installed on the outer wall of the lens of the night vision device body 3. The LED red light ring 1 can emit invisible or near-infrared light to supplement the observation area in low-light or no-light environments. The LED red light ring 1 is usually composed of multiple red or near-infrared LED beads arranged in a uniform ring. The multiple beads are set on a PCB substrate. The specific structure of the LED red light ring 1 is prior art and therefore is not disclosed in this application document.
[0024] To provide supplemental lighting for the lens of the night vision device 3, a protective box 2 is fixedly installed near the side of the lens of the night vision device 3, and a mounting lever 6 is fixedly installed on the side of the lens cover 5. The two protective boxes 2 have horizontal sliding grooves 21 on their sides, and the mounting lever 6 extends into the horizontal sliding grooves 21. The height of the horizontal sliding grooves 21 matches the height of the mounting lever 6. The horizontal sliding grooves 21 restrict the mounting lever 6 to move only in the horizontal direction. It should be noted that since the mounting lever 6 is directly fixed to the side of the lens cover 5 and cannot move along the lens axis of the night vision device 3, the entire structure of the lens cover 5 can only be used for night vision devices 3 with non-retractable objective lenses.
[0025] The protective box 2 is equipped with a common drive assembly. The common drive assembly drives the two lens caps 5 to open or close the lenses simultaneously. The common drive assembly includes a first push rod 12, a second push rod 121, and a common block 11. The common block 11 has a mounting groove 110 on its side. One side of the mounting groove 110 is rotatably connected to one end of the second push rod 121. The other end of the second push rod 121 is rotatably connected to the side of one of the mounting levers 6. The first push rod 12 is rotatably connected to the side of the common block 11 opposite to the mounting groove 110. The other end of the first push rod 12 is rotatably set on the side of the other mounting lever 6. The common block 11 has a reset guide assembly on its side.
[0026] The reset guide assembly includes a U-shaped rod 7, a vertical column 9, a vertical spring 8, and a common rod 4. The common rod 4 is fixedly installed on the inner wall of the protective box 2. The common rod 4 is movably inserted into the vertical column 9 in the vertical direction. The U-shaped rod 7 is fixedly installed on the top of the vertical column 9. One end of the U-shaped rod 7 is fixedly installed on the side of the common block 11. The bottom of the U-shaped rod 7 is fixedly connected to one end of the vertical spring 8. The other end of the vertical spring 8 is fixedly installed on the top of the common rod 4. Therefore, the U-shaped rod 7 can move in the vertical direction through the vertical column 9. In addition, in order to avoid affecting the rotation of the second push rod 121, a slot is provided on the top of the U-shaped rod 7.
[0027] The protective case 2 has an extension edge 22 fixedly installed on the top side away from the lens. The common block 11 has a pressing and folding rod 10 fixedly installed on the top. The pressing and folding rod 10 includes a horizontal section and a vertical section. There is a gap between the horizontal section of the pressing and folding rod 10 and the top of the extension edge 22. The horizontal section of the pressing and folding rod 10 extends into the lower part of the extension edge 22. The extension edge 22 is designed to prevent the lens cover 5 from being accidentally opened when the night vision device is accidentally dropped and the pressing and folding rod 10 is impacted.
[0028] For details, please refer to the following: Figure 4 The two mounting levers 6 of the two lens caps 5 are staggered. In order to make the two lens caps 5 move closer to each other when the common block 11 is pressed down, the bottom of the first push rod 12 is rotatably set to the mounting lever 6 on the left lens cap 5, and the bottom of the second push rod 121 is rotatably set to the mounting lever 6 on the right lens cap 5.
[0029] The specific implementation steps and principles of this utility model are as follows:
[0030] In the initial state, the two lens caps 5 are in the position where the night vision device lens is closed. At this time, the vertical spring 8 is in its original length state, and there is a gap between the horizontal section of the holding lever 10 and the top of the extension edge 22. The user inserts both hands into the top of the holding lever 10 to hold the night vision device body 3, which moves the holding lever 10 down and compresses the vertical spring 8. The common block 11 drives the two mounting levers 6 to move closer to each other through the first push rod 12 and the second push rod 121, thereby moving the two lens caps 5 laterally away from the lens.
[0031] When the user accidentally drops the night vision device, the holding lever 10 is reset by the vertical spring 8, which in turn resets the common block 11. The common block 11 then resets the two lens caps 5 via the first push rod 12 and the second push rod 121.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
