Description

Technical Field

[0001] This invention belongs to the field of aiming system technology, and specifically relates to an aiming device with thermal imaging function. Background Technology

[0002] The light emitted from the LED chip installed on the existing firearm sight is reflected by the cemented lens to form the aiming spot. The LED chip emits light in the 560±80nm or other wavelength bands. The light emitted from the LED often contains multiple colors such as red, yellow, and green. These multiple colors of light are reflected by the narrow-band interference filter and long-wavelength cutoff filter coated on the cemented lens. Light with wavelengths of 545±15nm and greater than 600nm is reflected into the human eye. At the same time, the human eye observes the target and the surrounding environment through the cemented lens and shoots by aiming the aiming spot to coincide with the target.

[0003] Patent application No. 201920048750.4 discloses an optical system for a reflective red dot sight that improves monochromaticity and concealment. It includes an LED chip and a lens for reflecting the light emitted from the LED chip. A filter with a narrow-band interference filter film is placed near the LED chip and positioned between the LED chip and the lens. This filter filters out a wider band of light emitted by the LED chip, except for the center wavelength, thus improving the monochromaticity of the light entering the eye. The light energy of light other than the center wavelength emitted from the filter is weakened or cut off. The light energy of the center wavelength emitted from the filter illuminates the cemented reflective surface of the lens, which is coated with a cutoff film that cuts off the center wavelength. Therefore, when looking towards the lens from a distance, it is difficult to detect the light emitted from the lens, thereby improving the concealment of the sight. However, this method of directly observing the target with the human eye is inconvenient in shooting environments at long distances or in poor lighting conditions, making it difficult to accurately judge or identify the target.

[0004] Patent application No. 201922462324.8 discloses a dual-light, three-color optical system and its sight, including a green light chip module, a red light chip module, and a right-angle prism. The green and red light chip modules are arranged perpendicularly. The geometric center of the cubic prism is located at the intersection of the emitted light rays from the green and red light chip modules. A composite film is coated on the diagonal surface of the cubic prism extending from the angle bisector of the angle between the emitted light rays from the green and red light chip modules. This composite film is used for total internal reflection of the emitted red light from the red light chip module and transmission of the emitted green light from the green light chip module. By using two mutually perpendicular red and green light sources, and with the help of a prism and a total internal reflection or transmission film, the generation of green, red, or yellow light can be achieved through a control circuit, greatly reducing the number of light sources and the size and weight of the sight. However, this still relies on direct observation of the target by the human eye, which is inconvenient in shooting environments with long distances or poor lighting conditions, making it difficult to accurately judge or identify the target.

[0033] Example 1

[0034] To address the problems of existing sight optical systems, such as the significant influence of ambient light on target observation and identification, difficulty in target recognition, and easy exposure of the shooter when the human eye directly observes the target.

[0035] This invention provides a method such as Figures 1-4 The sight shown includes a body 1. Below the body 1 are a battery cover assembly 11, a thermal imaging lens assembly 12, a thermal imaging core assembly 13, a battery 14, an adjustment assembly 7, and a beam splitter display assembly 8. The battery cover assembly 11 and the thermal imaging lens assembly 12 are arranged side-by-side. The battery 14 is located behind the battery cover assembly 11 and primarily powers the battery cover assembly 11 and the thermal imaging lens assembly 12.

The adjustment assembly 7 also includes an adjustment screw 43, which is positioned behind the main body 17 of the adjustment assembly. By pulling or pushing the main body 17 of the adjustment assembly with the adjustment screw 43, the front-to-back position can be adjusted.

[0036] Furthermore, such as Figure 10 As shown, the battery cover assembly 11 is replaced by an infrared illumination assembly 28, and the thermal imaging lens assembly 12 is replaced by a low-light night vision camera module 48.

A solar charging panel 6 is provided in the upper middle part of the main body 1, and the solar charging panel 6 mainly provides power to the LED graphic chip 20.

[0038] Furthermore, a first main control board 15 and a second main control board 16 are provided on the right side of the main body 1, with the first main control board 15 located in front of the second main control board 16; the first main control board 15 corresponds to Figure 1 The three buttons on the front right side control the battery cover assembly 11, increasing or decreasing the brightness of the inner red dot; the second main control board 16 corresponds to...

[0039] Furthermore, the adjustment component 7 includes an adjustment component body 17, on which an LED base 18 is disposed, the LED base 18 being connected to a chip holder 19, and an LED graphic chip 20 being disposed on the chip holder 19; a slope 21 is disposed on the lower left side of the adjustment component body 17, the slope 21 being in contact with a sloping top block 22, and a first fine-tuning screw 23 is disposed on the left side of the sloping top block 22; a transverse top block 24 is disposed on the right side of the adjustment component body 17, and a second fine-tuning screw 25 is disposed on the right side of the transverse top block 24; a transverse top spring 26 is also disposed between the adjustment component body 17 and the transverse top block 24; and a compression spring 27 is disposed above the adjustment component body 17.

[0040] Furthermore, the beam-splitting display assembly 8 includes a beam splitter mount 29, a beam splitter 30 disposed within the beam splitter mount 29, a display screen 31 disposed on the right side of the beam splitter mount 29, and a beam splitter cover 32 disposed above the beam splitter mount 29. The display screen 31 and the light incident on the beam splitter 30 from the LED graphic chip 20 are positioned at a 90° angle. It should be noted that the aiming light spot emitted by the LED graphic chip 20 and the image played on the display screen 31 are respectively reflected by the beam splitter 30 and transmitted through the beam splitter 30.

[0041] Furthermore, the main function of the beam splitter 30 is to perform light fusion. Therefore, the beam splitter 30 can also be replaced by a semi-transparent and semi-reflective plane mirror.

[0042] Furthermore, a conductive cylinder 33 is provided around the battery 14, and a conductive plate 34, a buffer pad 35, a conductive spring 36, and a positive electrode plate 37 are sequentially arranged behind the battery 14. This is a conventional design for the battery 14.

[0043] Furthermore, the thermal imaging lens assembly 12 also includes a connecting sleeve 38, a lens gasket 39, a sealing gasket 40, and a mechanism pressure ring 41. The connecting sleeve 38, lens gasket 39, sealing gasket 40, and mechanism pressure ring 41 are sequentially fitted onto the thermal imaging lens to fix and protect the lens. A mechanism buffer pad 42 is provided between the thermal imaging lens assembly 12 and the thermal imaging mechanism assembly 13 to prevent direct contact and collision between the thermal imaging lens assembly 12 and the thermal imaging mechanism assembly 13.

[0044] Furthermore, a data charging port 45 is provided on the right side of the main body 1 and behind the battery 14, and a charging indicator light 46 is provided next to the data charging port 45.

[0045] Furthermore, a switch indicator light 47 is provided on the left side of the main body 1, next to the second main control board 16.

[0046] Furthermore, the light emitted by the LED graphic chip 20 and the display screen 31 passes through the beam splitter 30 and then enters the lens 3. Under the control of the main control board 1, the LED graphic chip 20 provides the aiming spot. The light emitted by the LED graphic chip 20 is reflected or transmitted through the beam splitter 30 and then enters the lens 3. After being reflected by the lens 3, it enters the eye of the shooter. At the same time, the shooter's eye can directly observe the target and the surrounding scene through the lens 3. In addition, the thermal imaging lens assembly 12 can collect video images of the target and the surrounding scene. The collected video images are played synchronously through the display screen 31. After being transmitted or refracted through the beam splitter 30, they enter the lens 3. After being reflected by the lens 3, they enter the eye of the shooter. The source of the shooter's observation of the target and the surrounding scene can be the target and the surrounding scene observed directly, or it can be the video recording projected by the thermal imaging lens assembly 12 on the display screen 31. This can overcome the problems of unclear observation and great influence from environmental factors caused by the existing sights where the shooter directly observes the target and the surrounding scene through the lens 3.

[0047] Furthermore, battery 14 can be a CR123A, 18650, 18350, or polymer lithium battery; LED graphics chip 20 can be an HK-882 LED chipset; display screen 31 can be Micro LED or OLED; thermal imaging lens assembly 12 can use Arrow's thermal imaging module; infrared illumination assembly 28 uses an 850nm wavelength LED or laser light source; and low-light night vision camera module 48 uses Sony's 482 low-light night vision module. The main control board is customized based on the product requirements of using LED graphics chip 20, display screen 31, thermal imaging lens assembly 12, infrared illumination assembly 28, and low-light night vision camera module 48. For example, a main control board model 21109 can be developed based on the HK-882 LED chipset, Micro LED, Arrow, Guide, or other thermal imaging modules, and a Sony low-light CMOS sensor.

[0048] Furthermore, depending on the application scenario, the thermal imaging lens assembly 12 can be set separately from the sight. For example, the images captured by the thermal imaging lens assembly 12 can be directly transmitted to the sight or AR glasses via wireless or wired means, thereby improving the recognition capability of the target and expanding the application environment of the red dot sight. Users can freely choose to use the thermal imaging lens assembly 12 or the infrared illumination assembly 28 and the low-light night vision camera module 48 in combination with the sight according to their own application scenario.

[0049] In summary, this sight with thermal imaging capability integrates infrared illumination, thermal imaging lens imaging, and human eye observation of the target. This allows for the assistance in observing or identifying the target, and then using the aiming dot to pinpoint the target for firing preparation. This sight with thermal imaging capability reduces the impact of environmental factors such as light and distance on firing accuracy, and also reduces the risk of exposure for the shooter. It allows target identification to go beyond just human observation, improving target identifiability and expanding the application environment of red dot sights.

[0050] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
