Description

Technical Field

[0001] This utility model relates to the field of aiming scope technology, and in particular to a dual-light source red dot sight. Background Technology

[0002] Red dot sights, as optical devices that provide a rapid aiming point, have been widely used in various fields. To improve reliability, existing technologies have developed red dot sights with dual light source designs. By incorporating two independent light sources within the sight body, the user can switch to the other light source if one fails, thus maintaining aiming functionality.

[0003] However, existing dual-light source red dot sights typically arrange the two light sources parallel to each other along the optical axis of the sight. This layout directly leads to a significant increase in the overall length of the sight, making it bulky, inaccessible, and more susceptible to damage from impacts due to its excessive length. It also disrupts the overall balance when mounted on the weapon. Therefore, a new type of red dot sight is needed that can effectively reduce the size of the product and improve its structural compactness while maintaining the redundancy of the dual light sources. Utility Model Content

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0025] refer to Figure 1 , Figure 4 and Figure 5In a preferred embodiment, the dual-light source red dot sight 100 includes: a housing 1, one end of which has a first opening 11 and the other end has a second opening 12, and a through channel 13 extending from the first opening 11 to the second opening 12 is formed inside the housing 1; a first light source assembly 2 and a second light source assembly 3, which are installed in the through channel 13 and arranged vertically in a height direction perpendicular to the center line L of the through channel 13, wherein the first light source assembly 2 is used to emit a first light beam 21 and the second light source assembly 3 is used to emit a second light beam 31; and a light adjustment module 4, which is installed in the through channel 13 and is used to adjust the light emitted by the first light source assembly 2 and the second light source assembly 3. This embodiment arranges the two light sources vertically in a stacked manner, which occupies less lateral space and has a more compact structure compared to a dual-light source arrangement on the same horizontal line. The centerline L refers to the length direction of the sight. When the sight is horizontal to the ground, the two light sources are arranged one above the other, and only their vertical position is limited; their horizontal and vertical positions are not limited. That is, the first light source assembly 2 and the second light source assembly 3 can be located at any position on their respective horizontal planes. The through channel 13 constitutes the main cavity for light propagation and lens mounting. The first opening 11 is usually an exit window, and the second opening 12 is usually an entrance window, or the first opening 11 can be an entrance window and the second opening 12 can be an exit window. The shape of the outer shell 1 can be cylindrical, square, or other polygonal cylindrical structures that conform to aerodynamic and aesthetic design. By arranging the two light source assemblies vertically, the length of the sight is greatly shortened, achieving miniaturization and compactness of the overall structure. This not only improves portability and aesthetics but also enhances structural strength and stability, making it perform better when subjected to recoil or impact. At the same time, this layout provides new space for the integrated design of the internal optical path. Having two light source assemblies also allows the other light source assembly to be activated when one light source assembly fails, improving redundancy.

[0026] refer to Figure 4 and Figure 5In a preferred embodiment, the first light source assembly 2 and the second light source assembly 3 are arranged in a staggered manner in a direction perpendicular to the centerline L of the through channel 13. "Staggered arrangement" means that the first light source assembly 2 and the second light source assembly 3 differ not only in height but also in their front-to-back positions; that is, one light source assembly is located diagonally above or below the other. The angle and distance of the stagger can be optimized according to the layout of the internal optical elements to best utilize space and ensure unobstructed light path. The staggered arrangement in this embodiment provides greater design flexibility, better avoids structural interference between the two light source assemblies, facilitates installation and wiring, and provides ample space for complex optical path systems.

[0027] In other embodiments, the first light source assembly 2 and the second light source assembly 3 are arranged aligned in a direction perpendicular to the centerline L of the through channel 13. This vertical arrangement is another preferred embodiment. "Aligned arrangement" means that the two light source assemblies are approximately located at the same position in the horizontal direction (i.e., the front-to-back direction), but are strictly arranged one above the other in the vertical direction. In this layout, the two light source assemblies can share some mounting structures or circuit boards, further simplifying the internal structure and making the light source layout most compact. This minimizes the projected size of the sight in both length and width, achieving extreme miniaturization. This layout is particularly suitable for applications with strict requirements on lateral volume.

[0028] refer to Figure 4 and Figure 5The light adjustment module 4 includes: a first collimating lens 46, which is disposed on the path of the first beam 21 and is used to collimate the first beam 21; a second collimating lens 47, which is disposed on the path of the second beam 31 and is used to collimate the second beam 31; a first reflecting mirror 41, which is installed on the path of the first beam 21 after being collimated by the first collimating lens 46 and reflects the first beam 21; a filter 42, which is installed on the path of the first beam 21 after being reflected by the first reflecting mirror 41 and reflects the first beam 21, and allows the second beam 31 to pass through; a second reflecting mirror 43, which is installed on the path of the first beam 21 and the path of the second beam 31 after being reflected by the filter 42 and reflects both the first beam 21 and the second beam 31; and a beam splitter 44, which is installed on the path of the beam after being reflected by the second reflecting mirror 43 and reflects the beam to the human eye. In this embodiment, a series of lenses are used to gradually integrate and adjust the scattered light emitted from two light sources at different positions (top and bottom) into a parallel aiming beam. The first reflecting mirror 41 and the second reflecting mirror 43 can be single-sided or double-sided mirrors, and the filter 42 can be a dichroic filter or other beam splitter capable of this function; no limitation is made here. In this embodiment, the side of the filter 42 facing the second light source assembly 3 allows a specific beam to pass through, while the side facing away from the second light source assembly 3 reflects the same beam. This optical system optically fuses two spatially separated light sources into the same line of sight, ensuring that regardless of whether the light source comes from above or below, the final aiming point is clear, distortion-free, and parallax-free.

[0029] refer to Figure 4 In a preferred embodiment, the beam splitter 44 is tilted towards the second light source assembly 3, and the direction of the beam emitted after reflection by the beam splitter 44 is opposite to the direction of the emitted beams of the first light source assembly 2 and the second light source assembly 3. The figure schematically illustrates the light paths of the first beam 21 and the second beam 31 from emission through the light adjustment module 4 to exiting the aiming scope. It can be understood that since the filter 42 is a single-sided lens, one side can reflect the first beam 21, while the other side allows the second beam 31 to pass directly through. The coated surface of the beam splitter 44 is tilted towards the internal light source, reflecting the light from the light source out of the aiming scope.

[0030] refer to Figure 5In another preferred embodiment, the beam splitter 44 is tilted away from the first light source assembly 2, and the beam emitted after reflection by the beam splitter 44 has the same emission direction as the emitted beams of the first light source assembly 2 and the second light source assembly 3. The figure schematically illustrates the light paths of the first beam 21 and the second beam 31 from emission through the light adjustment module 4 to exiting the aiming scope. It can be understood that since the filter 42 is a single-sided lens, one side can reflect the first beam 21, while the other side allows the second beam 31 to pass directly through. The coated surface of the beam splitter 44 is tilted away from the internal light source, reflecting the light from the light source out of the aiming scope.

[0031] refer to Figure 2 In a preferred embodiment, the first light source component 2 further includes a first adjustment mechanism 22, and the second light source component 3 further includes a second adjustment mechanism 32. The first adjustment mechanism 22 and the second adjustment mechanism 32 are used to independently adjust the light emission characteristics and power on / off status of the first light source component 2 and the second light source component 3, respectively. Preferably, the first adjustment mechanism 22 and the second adjustment mechanism 32 are button adjustments or other adjustment methods. The light emission characteristics include, but are not limited to, brightness, color, and reticle patterns (such as dots, circles, or a combination of dots and circles). The two adjustment mechanisms can be physically independent or logically independent at the software level through a multi-functional controller, thus achieving independent and precise control of the two light sources. Users can set different parameters for each light source according to specific applications, greatly improving the applicability of the product and the user experience.

[0032] refer to Figure 2 In a preferred embodiment, the first adjustment mechanism 22 and the second adjustment mechanism 32 are physical buttons, touch switches, or adjustment screws. Physical buttons and adjustment screws are easy to operate while wearing gloves, while touch switches offer a more modern and technological feel.

[0033] refer to Figure 1 and Figure 3 In a preferred embodiment, the first light source assembly 2 further includes a first wind deflection adjustment port 23 and a first elevation angle adjustment port 24, which are used to adjust the wind deflection angle and elevation angle of the first beam 21, respectively; the second light source assembly 3 further includes a second wind deflection adjustment port 33 and a second elevation angle adjustment port 34, which are used to adjust the wind deflection angle and elevation angle of the second beam 31, respectively.

[0034] refer to Figure 1In a preferred embodiment, the dual-light source red dot sight 100 further includes a first power supply module 5 and a second power supply module 6 disposed within the housing 1. The first power supply module 5 supplies power to the first light source assembly 2, and the second power supply module 6 supplies power to the second light source assembly 3, thus forming two independent light source systems. One light source system consists of the first light source assembly 2 and the first power supply module 5, while the other light source system consists of the second light source assembly 3 and the second power supply module 6. When one light source system malfunctions, the other system can still operate independently without affecting the use of the sight. Both the first power supply module 5 and the second power supply module 6 include their own circuitry and batteries, and the batteries are detachably connected, allowing them to be removed from the outside for replacement and charging.

[0035] This application achieves a compact scope structure by arranging two light source assemblies vertically and integrating two light source systems into the scope body. Furthermore, it allows for immediate switching to the other light source in the event of a malfunction in either light source, further enhancing redundancy.
