Description

Technical Field

[0001] This utility model relates to the technical field of infrared-enhanced night vision imaging devices, and in particular to an infrared-enhanced night vision imaging device. Background Technology

[0002] Infrared-enhanced night vision imaging devices, typically referring to infrared night vision devices or night vision goggles, emit an infrared beam to illuminate the target and convert the reflected infrared image into a visible light image. This allows for clear visibility of targets even in complete darkness, and is commonly used in military, public safety, and civilian applications.

[0003] According to the search, the Chinese patent "An Image Intensifier and Far-Infrared Image Fusion Technology Helmet Night Vision Device Integrated Machine" authorized announcement number "CN220438654U" uses a fixing method of springs, blocks and buckles. Once the night vision device has a problem and needs to be repaired or replaced, the problem can be solved directly by simple disassembly and replacement, without the need for large-scale repair of the entire helmet.

[0004] In the aforementioned application, when personnel are wearing helmets and performing tasks outdoors, the impact generated by their movement and various actions is transmitted to the connection between the helmet and the night vision device. This can easily cause the buckle to detach from the locking block, resulting in the night vision device becoming loose on the helmet and affecting its use.

[0005] Therefore, an infrared-enhanced night vision imaging device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an infrared-enhanced night vision imaging device to solve the above-mentioned problems, thereby improving the instability of night vision devices mounted on helmets.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: an infrared-enhanced night vision imaging device, comprising: a mounting frame, wherein a night vision device is mounted on the inner wall of the mounting frame, a spring is fixedly connected to the inner top wall of the mounting frame, a locking block is fixedly connected to the bottom end of the spring, and the surface of the locking block is engaged with the inner wall of the night vision device; and a reinforcement mechanism, comprising a rotating rod rotatably connected to the top of the locking block, a stop block fixedly connected to the upper surface of the rotating rod, a magnetic rod slidably connected to the upper surface of the rotating rod, and a magnetic ring fixedly connected to the upper inner wall of the rotating rod, wherein the magnetic ring and the magnetic rod attract each other with opposite poles, and the lower surface of the magnetic rod is engaged with the inner wall of the stop block. The stop block limits the upward movement of the rotating rod and the locking block, and the magnetic rod and the magnetic ring lock the stop block, ensuring that the night vision device is securely mounted on the helmet.

[0008] Preferably, a fixing ring is fixedly connected to the lower end of the surface of the magnetic rod, and a sliding hole is provided at the top of the mounting frame. The surface of the fixing ring is slidably connected to the inner wall of the sliding hole, and a movable block is slidably connected to the inner wall of the sliding hole. Through the fixing ring, the sliding hole, and the movable block, the resistance to the upward movement of the magnetic rod is increased, reducing the probability of the magnetic rod falling into the stop block.

[0009] Preferably, a compression pad is fixedly connected to one side of the movable block, and the other end of the compression pad is fixedly connected to the inner wall of the sliding hole.

[0010] Preferably, a limiting block is fixedly connected to the inner top wall of the mounting frame. The limiting block restricts the range of the block's circumferential movement, ensuring that the magnetic rod can be precisely engaged within the block.

[0011] Preferably, a sealing block is fixedly connected to the top of the card block.

[0012] Preferably, the top of the mounting frame has a detachment hole, and the surface of the sealing block engages with the inner wall of the detachment hole. The sealing block effectively seals the inner wall of the detachment hole, preventing external impurities from entering the mounting frame through the detachment hole and ensuring relative cleanliness inside the mounting frame.

[0013] Preferably, annularly distributed elastic blocks are fixedly connected to the upper end of the inner wall of the sliding hole. These elastic blocks effectively block the upper end of the inner wall of the sliding hole, reducing the entry of impurities into the hole.

[0014] The beneficial effects of this utility model are:

[0015] By using a stop block, the upward movement of the rotating rod and the locking block is limited. By using a magnetic rod and a magnetic ring, the stop block is locked, thereby preventing the locking block from falling out of the night vision device under external impact. Compared with existing methods where the buckle is easily dislodged from the locking block when users are performing tasks outdoors, this method ensures that the night vision device is securely installed on the helmet.

[0016] By using a fixed ring, sliding hole, and movable block, the resistance to the upward movement of the magnetic rod is increased, reducing the probability of the magnetic rod falling out of the stop block. By using a limiting block, the range of the circular movement of the stop block is limited, ensuring that the magnetic rod can be accurately engaged in the stop block. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, an infrared-enhanced night vision imaging device includes: a mounting frame 1, a night vision device 2 disposed on the inner wall of the mounting frame 1, a spring piece 3 fixedly connected to the inner top wall of the mounting frame 1, a locking block 4 fixedly connected to the bottom end of the spring piece 3, and the surface of the locking block 4 being engaged with the inner wall of the night vision device 2; and a reinforcement mechanism 5, which includes a rotating rod 51 rotatably connected to the top of the locking block 4, a stop block 55 fixedly connected to the upper surface of the rotating rod 51, a magnetic rod 52 slidably connected to the upper surface of the rotating rod 51, a magnetic ring 53 fixedly connected to the upper inner wall of the rotating rod 51, the magnetic ring 53 and the magnetic rod 52 attracting each other with opposite poles, and the lower surface of the magnetic rod 52 being engaged with the inner wall of the stop block 55.

[0024] A helmet is fixedly connected to the rear end of the mounting frame 1. The night vision device 2 consists of an infrared sensor, an image intensifier, a display system, and an optical system. The infrared sensor inside the night vision device 2 has high sensitivity and can efficiently capture infrared radiation. By sensing infrared radiation, it improves visibility in nighttime or low-light environments and provides clear visual information. Through image intensification technology, it improves the contrast and detail of the image, enhancing the observation effect. It is not limited by light conditions and is suitable for various nighttime or low-light environments. It can adapt to changes in different lighting conditions and provide stable imaging effects.

[0025] When the night vision device 2 needs to be installed on the helmet, snap the night vision device 2 into the mounting frame 1. At this time, loosen the rotating rod 51. The elastic force of the spring 3 pushes the rotating rod 51 and the locking block 4 to move down, so that the locking block 4 is snapped into the night vision device 2. Then rotate the rotating rod 51. The rotation of the rotating rod 51 drives the stop block 55 to move in a circular motion to a suitable position, pushing the magnetic rod 52 to move down, so that the magnetic rod 52 is snapped into the stop block 55 and attracted into the magnetic ring 53, thereby making the night vision device 2 securely installed on the helmet. At this time, when the user wears the helmet to perform outdoor tasks, the night vision device 2 will not loosen on the helmet when subjected to impact.

[0026] like Figure 3-4 As shown, a fixing ring 54 is fixedly connected to the lower end of the surface of the magnetic rod 52. A sliding hole 58 is provided on the top of the mounting frame 1. The surface of the fixing ring 54 is slidably connected to the inner wall of the sliding hole 58. A movable block 56 is slidably connected to the inner wall of the sliding hole 58. A compression pad 57 is fixedly connected to one side of the movable block 56. The other end of the compression pad 57 is fixedly connected to the inner wall of the sliding hole 58. An elastic block 512 distributed in a ring is fixedly connected to the upper end of the inner wall of the sliding hole 58.

[0027] The magnetic rod 52 is pushed down, causing the fixed ring 54 to move down within the sliding hole 58. The fixed ring 54 moves down and touches the surface of the movable block 56. It continues to move down and pushes the movable block 56 to move laterally, causing the compression pad 57 to be squeezed. After the fixed ring 54 moves down past the movable block 56, the elastic recovery of the compression pad 57 pushes the movable block 56 to move laterally, so that the bottom of the movable block 56 contacts the top of the fixed ring 54, increasing the resistance to the upward movement of the movable block 56.

[0028] like Figure 3-4 As shown, a limiting block 59 is fixedly connected to the inner top wall of the mounting frame 1, and a sealing block 511 is fixedly connected to the top of the locking block 4. A release hole 510 is opened at the top of the mounting frame 1, and the surface of the sealing block 511 is engaged with the inner wall of the release hole 510. The compression pad 57, the sealing block 511, and the elastic block 512 are all rubber components.

[0029] In use, the night vision device 2 is snapped into the mounting frame 1. Then, the rotating rod 51 is loosened, and the elastic force of the spring piece 3 pushes the rotating rod 51 and the locking block 4 downwards, causing the locking block 4 to engage with the night vision device 2. The rotating rod 51 is then rotated, causing the stop block 55 to move in a ring until it contacts the limiting block 59. The rotation of the rotating rod 51 is stopped, pushing the magnetic rod 52 downwards, causing it to engage with the stop block 55 and be attracted to the magnetic ring 53. The downward movement of the magnetic rod 52 causes the fixing ring 54 to move downwards, contacting the movable block 56 and moving laterally, thus compressing the compression pad 57. After the fixing ring 54 moves downwards past the movable block 56, the elastic recovery of the compression pad 57 pushes the movable block 56 laterally, causing the bottom of the movable block 56 to contact the top of the fixing ring 54, thereby securing the night vision device 2 firmly onto the helmet.

[0030] It should be noted that the mounting frame 1, night vision device 2, magnetic rod 52 and magnetic ring 53 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the night vision device 2 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
