AI Technical Summary
In the traditional red dot aiming system, the red dot light source adopts a one-time reflection method, causing part of the emitted light to be exposed to the external environment, increasing the exposure risk of users.
By adopting the two reflections, the light beam of the red dot emitter passes through the first half-transmissive half-reflective lens, the visible lens group and the second half-transmissive half-reflective lens to form a red dot spot and reflect it onto the target object, effectively reducing light leakage.
Through the two reflections, the risk of red dot light leaking from the edges or surface of the mirror is significantly reduced, and the risk of exposure to the user is reduced.

Abstract
Description
Technical Field
[0002] This application belongs to the technical field of firearm sights, and particularly relates to an infrared red dot fusion sight.
Background Art
[0004] Traditional red dot sighting systems are widely used in various military and civilian fields, such as firearm aiming, archery, shooting training, etc. However, in traditional red dot sighting systems, the light source of the red dot uses a single reflection method, which may cause a part of the outgoing light to be exposed to the external environment, thereby increasing the exposure risk of the user. Specifically, traditional red dot sighting systems usually include a red dot emitter and a reflector. The red dot emitter generates a red dot light spot, and then reflects the red dot light spot to the target object through the reflector. However, since the surface of the reflector is not completely reflective, a part of the red dot light spot will leak out from the edge of the reflector or the tiny pores on the surface, and thus be detected by the external environment. This will expose the position of the user, especially in some usage scenarios that require covert operations.
Utility Model Content
[0006] To solve the problem in the prior art that the light source of the red dot in the traditional red dot sighting system uses a single reflection method, which easily causes a part of the outgoing light to be exposed to the external environment, this application provides an infrared red dot fusion sight.

Specific Embodiments
[0032] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer and more understandable, the following further details the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0033] Please refer to Figures 1 to 9, an infrared red dot fusion sight, comprising an upper housing 1, a lower housing 2 connected to the upper housing 1, an infrared component 3 disposed in the upper housing 1, and a red dot component 4 disposed in the lower housing 2. The red dot component 4 includes a red dot emitter 41, and a first semi-transmissive semi-reflective lens 42, a visible light lens group 43, a second semi-transmissive semi-reflective lens 44, and an imaging lens 45 through which the light beam of the red dot emitter 41 passes in sequence. The first semi-transmissive semi-reflective lens 42 and the second semi-transmissive semi-reflective lens 44 are arranged in parallel, and the light beam of the red dot emitter 41 vertically passes through the visible light lens group 43.
[0034] An infrared red dot fusion sight of the present application includes a red dot emitter, a first semi-transmissive semi-reflective lens, and a second semi-transmissive semi-reflective lens. The red dot emitter generates a red dot light spot, and then the red dot light spot is reflected by the first semi-transmissive semi-reflective lens and passes through the visible light lens group and then is reflected onto the second semi-transmissive semi-reflective lens. The second semi-transmissive semi-reflective lens then reflects the red dot light spot onto the target object. By this way of two reflections, the risk of the red dot light leaking from the edge or surface of the reflector can be effectively reduced, thereby reducing the exposure risk of the user.
[0035] Further, as a preferred implementation manner of this solution rather than a limitation, it further includes an infrared OLED component 31. The image emitted by the infrared OLED component 31 forms a first light beam after passing through the first semi-transmissive semi-reflective lens 42, the visible light lens group 43, and the second semi-transmissive semi-reflective lens 44 in sequence. The light beam of the red dot emitter 41 forms a second light beam after passing through the first semi-transmissive semi-reflective lens 42, the visible light lens group 43, and the second semi-transmissive semi-reflective lens 44 in sequence. The external scene image forms a third light beam after passing through the second semi-transmissive semi-reflective lens 44. The first light beam, the second light beam, and the third light beam coincide with each other.
[0036] In this embodiment, since most of the mainstream aiming devices on the market are single-optical-path visible light, low-light, or infrared aiming scopes, their observation scenarios are relatively limited and they cannot work in some extremely harsh environments, such as thick smoke and fog. The infrared aiming scope can just make up for this deficiency. The infrared aiming scope can be used both during the day and at night, but the infrared aiming scope cannot see the detailed features of the prey and cannot accurately distinguish what kind of animal it is. This embodiment realizes the fusion of infrared images, red dot light spots, and outdoor scene images. The infrared image emitted by the infrared OLED component forms a first light beam after passing through the first semi-transmissive semi-reflective lens, the visible light lens group, and the second semi-transmissive semi-reflective lens. The light beam of the red dot emitter forms a second light beam through the same optical path, and the outdoor scene image directly forms a third light beam through the second semi-transmissive semi-reflective lens. Through such a design, the first light beam, the second light beam, and the third light beam coincide in space, so that a fusion picture of infrared images, red dot light spots, and outdoor scene images is presented in the aiming scope. This fusion technology can improve the accuracy and efficiency of shooting. Especially in low-light environments, the infrared image can provide better target recognition and positioning capabilities. In addition, this embodiment also provides a possible implementation method, that is, by adjusting the positions and angles of the infrared OLED component, the red dot emitter, and the second semi-transmissive semi-reflective lens, the light beams emitted by the three can accurately coincide, so as to achieve a better fusion effect. Of course, there can also be other implementation methods, such as achieving the same fusion effect by using different optical elements or adjusting the optical path design.
[0037] Further, as a preferred implementation manner of this solution rather than a limitation, the exit pupil distance is 85 mm - 95 mm.
[0038] In this embodiment, when the exit pupil distance is set to 90 mm, compared with the traditional exit pupil distance of 50 mm, there is a larger distance between the human eye and the optical system, which can reduce the impact of the recoil of the firearm on the eye. When the firearm generates recoil, the long exit pupil distance can provide a buffer area to reduce the direct impact on the eye.
[0039] Further, as a preferred implementation manner of this solution rather than a limitation, the exit pupil diameter is 18 mm - 22 mm.
[0040] In this embodiment, when the exit pupil diameter is set to 20 mm, compared with the traditional exit pupil diameter of 5 - 10 mm, that is, the spot diameter formed when the light exits the optical system. The 20-mm exit pupil diameter means that more light can enter the human eye through the optical system, providing better brightness and field of view. When aiming, the user has an additional 15-mm eye offset range compared with the traditional 5-mm exit pupil diameter, that is, the adjustment range of the pupil up, down, left, and right within a radius of 7.5 mm can be increased, which can reduce the aiming difficulty caused by insufficient light or limited field of view.
[0041] Further, as a preferred implementation manner rather than a limitation of this solution, it further includes a first lens 5 disposed in the lower housing 2 and at the same horizontal height as the second semi-transmissive and semi-reflective lens 44. An opening 6 is formed in the lower housing 2 corresponding to the first lens 5, and a protective cover 7 hinged to the lower housing 2 and used to open or close the opening 6.
[0042] In this embodiment, the first lens can further focus or collimate the light beam passing through the second semi-transmissive and semi-reflective lens, improving the imaging quality; the setting of the protective cover can protect the opening and the first lens when the sight is not in use, preventing the entry of dust and dirt. In addition, there can be other implementation manners, such as setting a detachable filter or a focusing mechanism at the opening to further improve the imaging quality or meet different usage requirements.
[0043] Further, as a preferred implementation manner rather than a limitation of this solution, it further includes a polarizer 8 and a clamping mechanism 9 for holding the polarizer 8 or the protective cover 7 at the opening 6. The clamping mechanism 9 includes a clamping groove 91 formed on the lower housing 2, and a pinching piece 92 formed on the polarizer 8 and the protective cover 7. A clamping block 93 for being inserted into the clamping groove 91 is provided on the pinching piece 92.
[0044] In this embodiment, by adding a polarizer and a clamping mechanism for fixing the polarizer or the protective cover in the infrared red dot fusion sight, the function of polarization control of the light entering the sight is realized. Specifically, the clamping mechanism includes a clamping groove formed on the lower housing and a pinching piece formed on the polarizer or the protective cover. A clamping block is provided on the pinching piece. By inserting the clamping block into the clamping groove, the fixation of the polarizer or the protective cover can be achieved. Such a design can bring the following beneficial effects: First, the polarizer can eliminate or reduce the influence of reflected light and scattered light on the imaging quality, improving the clarity and contrast of the image; second, the setting of the clamping mechanism makes the installation and disassembly of the polarizer or the protective cover more convenient, facilitating the user to replace or adjust according to actual needs; finally, the design of the pinching piece and the clamping block makes the fixation more firm and reliable, not easy to loosen or fall off. After the protective cover is opened, the separable polarizer can be installed at the opening, and the clamping block on the polarizer is clamped with the clamping groove to complete the installation of the polarizer.
[0045] Further, as a preferred implementation manner rather than a limitation of this solution, the bottom of the protective cover 7 is hinged to the lower housing 2, and the hinge is located below the opening 6.
[0046] In this embodiment, the protective cover can effectively block the opening, preventing dust, water droplets or other foreign objects from entering the inside of the sight, which may affect the normal operation of the optical elements. Secondly, the hinge is arranged below the opening, so that the protective cover will not block the opening when it is opened, facilitating the user's observation and operation, and providing an installation position for the polarizing plate.
[0047] Furthermore, as a preferred embodiment of this solution rather than a limitation, it further includes a first power supply 10 electrically connected to the infrared OLED component 31, and a second power supply 11 electrically connected to the red dot component 4.
[0048] In this embodiment, the power supply systems of the infrared component and the red dot component are independently powered. Independent power supply can adjust the supply voltage or current of the two components respectively according to actual needs to meet different usage scenarios and requirements. The normal working duration of a general infrared system is generally 6 - 10 hours. When the two power supply systems are separated, when the infrared system runs out of power, the red dot system can be independently powered and can work for at least 50,000 hours.
[0049] Furthermore, as a preferred embodiment of this solution rather than a limitation, it further includes a shock-absorbing bracket 12 for connecting the lower housing 2 and the firearm.
[0050] In this embodiment, by adding a shock-absorbing bracket in the infrared red dot fusion sight for connecting the lower housing and the firearm, the shock-absorbing and protective function of the sight is realized. The shock-absorbing bracket can effectively reduce the damage to the infrared core detector caused by the instantaneous impact force generated when the firearm fires. It can buffer and absorb the vibration energy generated during shooting, reduce the impact on the infrared core detector, improve its service life and reliability, and improve shooting accuracy.
[0051] Furthermore, as a preferred embodiment of this solution rather than a limitation, the infrared component 3 further includes an infrared core component 32 and an infrared button component 33 provided on the upper housing 1.
[0052] In this embodiment, the enhancement of the infrared core component can improve the imaging quality and clarity of the sight in low-light environments, enhancing the user's observation and aiming capabilities. Secondly, the setting of the infrared button component enables the user to quickly adjust the infrared function without complex operations, improving the convenience and efficiency of use.
[0053] Furthermore, as a preferred embodiment of this solution rather than a limitation, the red dot component 4 further includes a red dot switch button 46, a red dot up-down adjustment knob 47, and a red dot left-right adjustment knob 48 provided on the lower housing.
[0054] In this embodiment, the red dot switch button enables the user to quickly turn on or off the red dot function as needed, improving the flexibility of use. Secondly, the settings of the red dot up / down adjustment knob and the red dot left / right adjustment knob allow the user to precisely adjust the position of the red dot light spot according to actual needs, enhancing the accuracy of aiming and shooting precision.
[0055] Further, as a preferred implementation manner of this solution rather than a limitation, it further includes a charging interface 100 electrically connected to the first power supply 10 and the second power supply 11.
[0056] Further, as a preferred implementation manner of this solution rather than a limitation, it further includes an infrared lens protection cover 200 detachably connected to the upper housing 1.
[0057] In this embodiment, the protection and convenient replacement of the infrared lens are realized. Specifically, the infrared lens protection cover can effectively block and protect the infrared lens, preventing dust, water droplets or other foreign objects from entering the lens interior and affecting its normal operation.
[0058] The working principle of this embodiment is as follows:
[0059] An infrared red dot fusion sight of the present application includes a red dot emitter, a first semi-transparent semi-reflective lens and a second semi-transparent semi-reflective lens. The red dot emitter generates a red dot light spot, which is then reflected by the first semi-transparent semi-reflective lens through the visible light lens group and then reflected onto the second semi-transparent semi-reflective lens. The second semi-transparent semi-reflective lens then reflects the red dot light spot onto the target object. By means of this two-time reflection method, the risk of red dot light leaking out from the edge or surface of the reflector can be effectively reduced, thereby reducing the exposure risk of the user.
[0060] The above are the implementation manners provided in combination with specific content, and it is not considered that the specific implementation of the present application is only limited to these descriptions. Any structure similar to the method of the present application, or several technical deductions or replacements made under the premise of the concept of the present application, should be regarded as the protection scope of the present application.
