Description
Technical Field
[0001] This invention relates to the field of firearm sights, specifically to a compact, day and night usable, high light transmittance, stable and reliable infrared and red dot fusion sight. Background Technology
[0002] A red dot sight, also known as a reflex sight or internal red dot sight, is a type of optical sight without magnification. Because the point of light incident on the eye in a red dot sight is always aligned with the red dot itself, accurate aiming is possible even if the eye is not on the central axis of the red dot sight. This improves shooting accuracy during high-speed movement or when the body is swaying, and therefore it is widely used in military firearms and even in the head-up displays of fighter jets.
[0003] Traditional red dot sights can only be used in bright daylight or nighttime environments. In low-light and nighttime conditions, targets are difficult to see, resulting in poor aiming performance and severely impacting tactical and technical effectiveness. To address this, red dot sights combining night vision and white light have emerged. However, because they require the simultaneous setup of red dot and night vision optical paths, which are then fused and collimated onto curved mirrors, existing fusion aiming systems are large and bulky, increasing exposure risk and weight. To address this, existing technologies employ a prism with a semi-transparent, semi-reflective coating placed between the curved mirror on the primary optical axis of the sight and the eyepoint. The red dot light source and the night vision imaging unit are positioned on opposite sides of the prism, fusing through reflection and transmission via the prism before being collimated onto the curved mirror and passing through the prism to the eye. This aforementioned technical solution, by using a prism to bend the optical path, shortens the size of the fusion aiming system, thereby reducing overall volume and weight. However, because the prism is located on the main optical axis of the scope, natural light, after passing through the curved reflector and the night vision image, after being reflected by the curved reflector, must pass through the prism again before entering the human eye. The prism's semi-transparent, semi-reflective coating significantly reduces light transmittance, thus affecting the clarity of targets viewed from a distance. Furthermore, the prism's large size and weight contribute to the still excessive size and weight of the fusion aiming system. While increasing the brightness of the night vision imaging unit can overcome the target clarity problem caused by the prism's low light transmittance, higher brightness leads to increased power consumption and affects battery life. In addition, existing technologies also involve placing a prism on one side of the main optical axis of the scope, setting an inclined beam splitter on the main optical axis of the scope, setting a red dot light source and a night vision imaging unit on both sides of the prism, and then setting a reflector and its lens group behind the prism. This allows the red dot and the night vision image to be fused by the prism and then enter the beam splitter through the reflector and lens group. After being reflected again by the beam splitter, the image enters the human eye. Although the light transmittance is improved compared to a prism with a semi-transparent and semi-reflective film, the additional beam splitter, reflector and lens group increase the complexity, weight and volume of the structure, and also weaken the improvement in light transmittance.
[0004] Furthermore, existing red dot sights generally employ a cylindrical or open (window-type) structure. The open structure is more common due to its simplicity. Open red dot sights typically have corresponding adjustment mechanisms to adjust for windage, ballistic compensation, and to eliminate the effects of manufacturing deviations in components. However, existing adjustment mechanisms often use a universal ball joint between the scope body and the base. While this achieves compensation adjustment, the universal ball joint can interfere with each other when adjusting for windage and ballistic compensation, leading to decreased adjustment accuracy. Moreover, the connection stability and rigidity of the universal ball joint are insufficient, making it prone to displacement or even cracking due to impacts during weapon transport, thus affecting accuracy.
[0005] In addition, the scope and the gun are mostly connected by a Picatinny rail. However, the scope is currently mounted on the Picatinny rail by two bolts and nuts or by two screws. This method is not only slow to mount and complicated to move and adjust, but the tightness of the nuts and bolts varies from person to person. Without special tools, it is difficult to achieve reliable tightening. Furthermore, this structure is generally locked with anti-slip washers, so the reliability after mounting is not high. There is also a technical solution that uses a wedge mechanism on the scope and a single screw to push the wedge block of the wedge mechanism to clamp the Picatinny rail. Although the clamping speed is significantly improved compared to the solution with two bolts and screws, and it can solve the problem of varying tightening degrees by different people, the tightening and loosening speed of bolts and screws is still relatively slow, and the self-locking function of the wedge mechanism makes it difficult to loosen, thus slowing down the overall clamping speed. Furthermore, since the locking and loosening of the wedge mechanism is more sensitive to changes in the self-locking angle, the wedge mechanism is less adaptable to firearms used in complex and demanding environments.

[0017] The beneficial effects of this invention are: 1. This invention places a beam splitter within the lower ventral cavity of the main mirror housing. A miniature display and a red dot light source are respectively positioned on either side of the beam splitter. An infrared night vision component is positioned parallel to the top or side of the mirror housing. Through the precise coordination of the beam splitter, miniature display, and red dot light source, the red dot and night vision images are optically fused. The fused beam is collimated by a collimating mirror on the object side of the principal optical axis and reflected into the eye, forming a virtual target and infrared image at infinity or a finite distance. The shooter can more quickly locate targets using the infrared image and can also aim and fire using the red dot target. Therefore, by controlling the switch of the infrared night vision component, turning on the red dot light source alone allows for rapid aiming during the day; while turning on and fusing the red dot light source and the infrared night vision component enables nighttime aiming and highlights heat sources, thus prominently displaying living targets with obvious infrared characteristics. This greatly improves the combat effectiveness of personnel, maximizes the advantages of each component, and allows for uninterrupted day and night use, enhancing the adaptability of the scope.
[0018] 2. This invention uses a beam splitter to achieve red dot and night vision fusion. Not only does the beam splitter not produce any aberrations, but it is only used for reflection and transmission, thus reducing image distortion compared to a prism. Moreover, the beam splitter effectively shortens the system volume by reversing the beam, and the beam splitter is smaller in size and weight than a prism, thus significantly reducing the size of the aiming scope. Furthermore, the main optical path in the main scope cavity contains only a collimating mirror, while the fusion optical path in the ventral scope cavity contains only a beam splitter, which significantly simplifies the overall optical path structure, and also significantly improves the light transmittance of the aiming scope and reduces the requirements for night vision image brightness, thereby improving the clarity of the image entering the human eye and the night vision endurance.
[0019] 3. This invention includes left-right adjustment components for the adjustable red dot light source and / or micro display, and a height adjustment component for the adjustable vertical position. Different screws are used to adjust the corresponding orientation and height, which not only avoids the mutual interference between orientation and height adjustments, but also allows for precise control of the adjustment amount, thus effectively improving adjustment accuracy. Furthermore, the guide blocks I and II of the left-right adjustment components are respectively attached to the beam splitter mount via inclined surfaces. Guide block I is threadedly connected to the left-right adjustment screws, and guide block II abuts against the elastic element I, ensuring a tight fit between guide blocks I and II and the beam splitter mount to eliminate gaps between components. This large-area surface contact improves the stability after adjustment.
[0020] 4. This invention uses a connecting seat as a base, and a through groove matching the structure of the rail is set at the bottom of the connecting seat. A wrench groove and an unlocking groove are set on one outer wall of the through groove of the connecting seat, and a locking groove is set on the other outer wall. A through hole I is set through the connecting seat to connect the wrench groove and the locking groove. Thus, by rotating the locking wrench with an eccentric wheel, the pull rod can be pulled to clamp or release the locking block in the locking groove, realizing quick clamping with the rail. Compared with the screw tightening or loosening structure, it can greatly improve the clamping efficiency. In addition, the locking block is provided with a side groove matching the structure of the rail, which can realize a large surface contact between the locking block and the rail for locking. It can also avoid stress concentration on the rail caused by surface or line contact during screw clamping, which can scratch the rail. The large surface contact can also improve the stability after locking, which is beneficial to improving the stability of the scope.
[0021] 5. The connecting seat of the present invention uses a locking wrench with an eccentric wheel structure to lock or release the locking block and the track by rotating the lever. Therefore, reliable clamping with the track can be achieved without special tools, avoiding the problem of varying tightening degrees from different people. Moreover, by setting a locking groove in the locking wrench and correspondingly setting an unlocking button that can be rotated into the locking groove, the reliability after clamping can be significantly improved. Furthermore, the locking wrench drives the eccentric wheel to rotate through the handle. Since the handle forms a lever effect with respect to the eccentric wheel, it can easily drive the eccentric wheel to rotate, thereby locking and releasing the locking block and the track. This avoids the problem of difficulty in releasing and sensitivity of the self-locking angle caused by the wedge structure, thus improving the adaptability of the application.
[0022] 6. The connecting seat of the present invention has a stepped hole on the locking block and an adjusting screw hole on the end face of the pull rod. At the same time, an adjusting nut with a through hole IV is provided in the stepped hole. An adjusting screw is passed through the through hole IV and the adjusting screw hole to connect the adjusting nut to the pull rod. A return spring II is provided between the locking block and the locking groove to abut. The return spring II can reliably abut the eccentric wheel of the locking wrench against the wrench groove. Moreover, when the rail is released, the locking block can be pushed to automatically disengage from the rail, thereby improving the reliability of clamping and the speed of release. Furthermore, by providing a guide block that slides into the guide hole of the connecting seat in the locking block, the stability of the side groove of the locking block and the rail can be effectively improved.
[0023] In summary, the present invention features a compact structure, usability day and night, high light transmittance, and stability and reliability. Attached Figure Description

[0043] The infrared night vision component 9 comprises a thermal imaging detector and / or a CMOS detector. The thermal imaging detector acquires far-infrared information in night vision mode, detecting the target's thermal radiation; while the CMOS detector acquires near-infrared information in night vision mode, detecting the near-infrared light reflected from the target. Selecting different detectors as needed can improve the system's environmental adaptability.
[0044] The infrared night vision component 9 is an existing night vision module for night vision goggles, which includes an objective lens group, an infrared photosensitive night vision element, and an image signal conversion function.
[0045] The microdisplay 5 is a Micro LED display or an OLED display.
[0046] Working principle and process of this invention: like Figures 1 to 3As shown, when working in an environment with sufficient natural light, the lens cover 13 is opened and the red dot light source 7 is activated. The light emitted by the red dot light source 7 is reflected by the beam splitter 4 and enters the collimating mirror 8. After being collimated by the collimating mirror 8 and fused with the transmitted external target, it enters the human eye, completing the fusion of visible light and red dot, and realizing rapid aiming during the day.
[0047] When working in environments with severely insufficient natural light, first close the lens cover 13, then activate the red dot light source 7, and simultaneously activate the infrared night vision component 9 to receive the far-infrared and / or near-infrared bands of the external environment and targets. After photoelectric conversion and image processing algorithms, the visible light image is displayed on the OLED display screen (i.e., the micro-display 5). The visible light image on the OLED display screen and the light emitted by the red dot light source 7 are fused together on the beam splitter 4. The fused light enters the collimating mirror 8 for collimation and reflection before entering the human eye, completing the fusion of infrared light and red dot, enabling nighttime aiming. Furthermore, the heat source prominence mode highlights living targets with obvious infrared characteristics, greatly improving the combat effectiveness of combat personnel.
[0048] Of course, when working in environments with insufficient natural light, such as dusk or bright moonlight, the lens cover 13 can be opened first, and then the red dot light source 7 and infrared night vision component 9 can be activated. The infrared image of the outdoor target is captured and photoelectrically converted by the infrared night vision component 9 and displayed as a visible light image on the OLED display (i.e., the micro display 5). The visible light image on the OLED display and the light emitted by the red dot light source 7 are fused together on the beam splitter 4. The fused light enters the collimating mirror 8 for collimation and reflection, and then is fused again with the visible light passing through the collimating mirror 8 before entering the human eye simultaneously. This completes the fusion of visible light, infrared light and red dot, thereby maximizing the advantages of each and improving aiming accuracy.
[0049] like Figures 3 to 7As shown, when adjusting the micro-display 5 and / or the red dot light source 7 left and right, insert a screwdriver or hex wrench into the groove of the left and right adjusting screw 113, and rotate the left and right adjusting screw 113 forcefully to overcome the resistance between the pin 119 and the toothed groove 117. The left and right adjusting screw 113 drives the guide block I 111 to move left and right in the mirror base groove. Since the guide block II 112 presses against the beam splitter base 3 under the elastic force of the elastic element I, the beam splitter base 3 presses against the guide block I 111. Therefore, the left and right movement of the guide block I 111 causes the beam splitter base 3 to move left and right as well, thereby realizing the left and right movement of the OLED display or the infrared light source 7. When the left and right adjusting screw 113 is rotated, the pin 119 continuously hits the toothed groove 117 and makes a sound, thereby obtaining positioning and circumferential indexing information. After adjustment, the head of pin 119 abuts against the toothed groove 117 to form a self-locking mechanism, preventing the left and right adjustment screw 113 from creeping due to vibration and affecting accuracy. Furthermore, the tight fit with the pressure ring 116 embedded in the outer hole of the stepped hole I on the mirror body 1 prevents the left and right adjustment screw 113 from dislodging due to large impacts. The principle and process of adjusting the up and down micro-display 5 and / or the red dot light source 7 are the same as the left and right adjustment.
[0050] like Figures 8 to 20 As shown, when the quick clamping mechanism of the rail is clamped with the rail, the connecting seat 2 of the present invention is slidably inserted into the rail through the through groove 202 (or the red dot sight is first installed on the top of the connecting seat 2). The connecting seat 2 is adjusted to a suitable position on the rail, and the middle part of the limiting protrusion 208 and the pull rod 220 are respectively inserted into the transverse groove of the rail. Then, the handle 232 of the locking wrench 230 is manually pressed down, which drives the eccentric wheel 231 to rotate and pull the pull rod 220. Thus, the locking block 210 is moved towards the rail by adjusting the nut 260 and adjusting screw 270, and finally the side groove 211 of the locking block 210 is clamped into the rail. As the eccentric wheel 231 rotates, the locking groove 234 gradually moves to the position of the locking claw 241. The unlocking button 240 rotates under the push of the return spring I 290, so that the locking claw 241 is inserted into the locking groove 234, completing the clamping and locking of the connecting seat 2 and the rail. When released, manually press down one end of the reset boss 242 of the unlock button 240 to disengage the locking claw 241 from the locking groove 234. At the same time, manually pull up the handle 232 to rotate the eccentric wheel 231. Under the push of the return spring II 280 on the side of the locking block 210, the locking block 210 moves away from the Picatinny rail. At this time, the sliding connecting seat 2 can be separated from the Picatinny rail, thereby realizing the clamping and disassembly of the Picatinny rail and the scope. The clamping force after clamping can be adjusted by rotating the adjusting screw 270 to adjust the distance between the end face of the optical rod 262 and the end face of the pull rod 220.
