Description

Technical Field

[0001] This utility model relates to the field of night vision equipment technology, and in particular to a night vision display. Background Technology

[0002] Night vision displays are a type of night vision equipment and an important component of modern military equipment. Soldiers use them extensively in nighttime combat, patrol, and reconnaissance missions. For example, night vision displays installed on tanks, armored vehicles, and other equipment allow operators to clearly observe the battlefield environment at night, including enemy troop deployments and equipment positions, thereby enabling effective command and firepower engagement.

[0003] To maintain good heat dissipation, existing night vision displays typically have ventilation holes or slots on their casings. However, in rainy weather, rainwater can enter the night vision display through these holes or slots, potentially causing short circuits and affecting its normal operation. Therefore, a new heat dissipation structure is needed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a night vision display to solve the problem mentioned in the background art, where existing night vision displays usually have heat dissipation holes or heat dissipation slots on the outer shell to maintain good heat dissipation. However, in rainy weather, rainwater can enter the interior of the night vision display through the heat dissipation holes or heat dissipation slots, which can easily cause short circuits and affect the normal use of the night vision display.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a night vision display, comprising:

[0007] Night vision display body;

[0008] A safe heat dissipation component includes a receiving groove, a baffle, a strip-shaped drainage groove, and an external drainage groove. The receiving groove is opened at the bottom of the night vision display body, the baffle is movably connected in the receiving groove, the strip-shaped drainage groove is opened on the baffle, and the external drainage groove is opened through the night vision display body on both sides of the receiving groove.

[0009] Furthermore, the strip-shaped drainage channel and the external drainage channel are on the same horizontal line.

[0010] Furthermore, the baffles are installed at a 45-degree angle at the receiving groove, and there are gaps between the baffles.

[0011] Furthermore, it also includes a convenient replacement component, which includes a mounting slot, a plug rod, and an L-shaped slot. The mounting slots are opened on both sides of the baffle, and the plug rod is movably connected in the mounting slot. An L-shaped slot is opened at the receiving slot on the inner wall of the night vision display body, and the plug rod movably inserts into the long end of the L-shaped slot.

[0012] Furthermore, the convenient replacement component also includes a spring, with one end of the spring fixedly connected to the rear baffle of the mounting slot, and the other end of the spring fixedly connected to the insertion rod.

[0013] Furthermore, the convenient replacement component also includes a pull block, which is fixedly connected to the top of the insertion rod, and the pull block is movably connected to the short end of the L-shaped slot, with the pull block protruding from the surface of the night vision display body.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] In this invention, the four inclined baffles do not contact each other, allowing heat to dissipate through the gaps and achieving good heat dissipation. Furthermore, each baffle can cover the bottom gap between adjacent baffles, preventing rainwater from directly entering the night vision display body through the bottom gap, thus achieving a waterproof effect. In addition, the strip-shaped drainage channel and the external drainage channel can divert the water flowing through the baffles to the outside of the night vision display body, further improving the waterproof effect and effectively preventing water ingress and short circuits.

[0016] Based on the aforementioned beneficial effects, by pulling the lever, the spring can be compressed, causing the insert rod to disengage from the L-shaped slot, thus enabling the quick removal of the baffle. After aligning the insert rod with the L-shaped slot, the spring returns to its original state after compression, allowing the baffle to be installed. This facilitates the quick replacement of damaged baffles, thereby shortening downtime and ensuring the normal operation of the night vision display. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-5 As shown, this embodiment is a night vision display, including:

[0031] Night vision display body 101;

[0032] The safe heat dissipation component includes a receiving groove 201, a baffle 202, a strip-shaped drainage groove 203, and an external drainage groove 204. The receiving groove 201 is opened at the bottom of the night vision display body 101. The baffle 202 is movably connected in the receiving groove 201. The strip-shaped drainage groove 203 is opened on the baffle 202. The external drainage groove 204 is opened through the night vision display body 101 on both sides of the receiving groove 201.

[0033] The opening of the receiving groove 201 provides a guarantee for the connection of the baffle 202 to the night vision display body 101. The strip-shaped drainage groove 203 and the external drainage groove 204 are used to drain the water that falls on the baffle 202.

[0034] The strip-shaped drainage channel 203 and the external drainage channel 204 are on the same horizontal line;

[0035] The spatial arrangement of these components ensures the smooth flow of water.

[0036] The baffle 202 is installed at a 45-degree angle at the receiving groove 201, with gaps between the baffles 202;

[0037] The installation method and location of the baffle 202 provide guarantees for both water blocking and heat dissipation.

[0038] The easily replaceable components include a mounting slot 301, a plug rod 302, and an L-shaped slot 303. The mounting slots 301 are opened on both sides of the baffle 202. The plug rod 302 is movably connected in the mounting slots 301. An L-shaped slot 303 is opened at the receiving slot 201 on the inner wall of the night vision display body 101. The plug rod 302 is movably inserted into the long slot end of the L-shaped slot 303.

[0039] The opening of the mounting slot 301 ensures the movable connection of the insertion rod 302. The insertion rod 302 and the L-shaped slot 303 work together to ensure the disassembly and installation of the baffle 202.

[0040] The easy-to-replace components also include a spring 304. One end of the spring 304 is fixedly connected to the rear baffle 202 of the mounting slot 301, and the other end of the spring 304 is fixedly connected to the plug rod 302.

[0041] The spring 304 ensures that the baffle 202 is under stress, thereby ensuring that the insertion rod 302 is firmly inserted into the L-shaped slot 303.

[0042] The easy-to-replace components also include a pull block 305, with the top of the plug 302 fixedly connected to the pull block 305, and the pull block 305 movably connected to the short end of the L-shaped slot 303. The pull block 305 protrudes from the surface of the night vision display body 101.

[0043] The pull block 305 is designed to make it easier for the user to pull the plug 302.

[0044] Working principle: When an external water droplet falls onto the baffle 202, the baffle 202 intercepts the water droplet. The intercepted water flows along the baffle 202 to the strip-shaped drainage channel 203, then through the strip-shaped drainage channel 203 to the external drainage channel 204, and finally flows onto the night vision display body 101 until it falls to the ground. When the baffle 202 is damaged and needs to be replaced, the pull blocks 305 at both ends are pulled inward. At this time, the insertion rod 302 transmits external force to the spring 304, and the spring 304 is compressed. At this time, the insertion rod 302 is in the mounting slot 301 and the L-shaped slot 303. Move the slot end (baffle 202 moves at the short slot end of the L-shaped slot 303) until the insertion rod 302 moves to the outside of the L-shaped slot 303. Then pull the baffle 202 upward to remove it. Then take out the new baffle 202 and simultaneously engage the insertion rods 302 on both sides of the baffle 202 with the L-shaped slot 303. Then press the insertion rods 302 inward to engage them with the L-shaped slot 303, thereby installing the new baffle 202. This step can achieve both heat dissipation and waterproofing, and facilitates the quick replacement of the baffle 202.
