Description

Technical Field

[0001] This invention belongs to the field of firearm shooting aids and aiming technology, specifically relating to a laser component and an inner red dot sight containing the laser component. Background Technology

[0002] Existing red dot sights and laser sights are generally two separate devices that need to be assembled together using a rail connector. This results in a bulky and inconvenient assembly, and the laser sight is prone to malfunction due to accidents (since the red dot sight is usually the primary aiming device, the laser sight is often mounted off-center). Furthermore, the two are not coaxial, leading to errors in the aiming baseline and increasing the difficulty of combining them. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies, such as inconsistency in use and errors in aiming baselines.

[0004] To achieve the above objectives, the present invention provides a laser assembly, including a base, wherein the base includes a laser module mounting portion on the front side, and a groove extending along its width direction is provided at the front end of the bottom of the laser module mounting portion; a screw hole is provided at the rear end of the base.

[0005] Furthermore, the two opposite outer surfaces of the base, the first and second outer surfaces, which extend along their length, are both arched surfaces.

[0006] Furthermore, the base also includes a cantilever section that extends backward and downward from the rear slope of the laser module mounting section, and the top surface of the cantilever section is coplanar with the top surface of the rear slope section to form a slope extending downward from front to back; the top surface of the slope is provided with multiple transverse grooves for eliminating stray light that are parallel and evenly distributed along its length; the adjustment reference is a screw hole opened at the rear end of the cantilever section.

[0007] Furthermore, a first laser module and a second laser module are installed side by side along the width direction within the laser module mounting section.

[0008] Furthermore, a laser module circuit board is fixed to the bottom surface of the laser module mounting part, located on the rear side of the groove.

[0009] A red dot sight containing the aforementioned laser component includes a cylindrical inner core with an objective lens assembly mounted at the front end. The key feature is that the adjustment reference is a screw hole; the laser component is disposed on the bottom surface of the inner core cavity, extending rearward from the inner side of the objective lens assembly along the length of the inner core; a protrusion that can be inserted into a groove is provided on the front side of the bottom surface of the inner core cavity; a through hole, coaxial with and directly opposite the screw hole, is provided on the rear side of the bottom surface of the inner core cavity, allowing a fixing screw to pass through the through hole from outside the bottom surface of the inner core and be threaded into the screw hole.

[0010] Furthermore, an LED light source assembly is fixed to the rear side of the bottom surface inside the cylindrical inner core; a first laser module and a second laser module are installed in the laser module mounting section, arranged side by side along its width direction. The parallel beams emitted from the LED light source assembly, the first laser module, and the second laser module are all projected onto the target through the objective lens assembly, and together with the LED light source assembly, they form a coaxial parallel beam after being reflected by the objective lens assembly.

[0011] Furthermore, a mounting hole is formed on the bottom surface of the inner cavity of the cylindrical inner core for placing the laser component into the cylindrical inner core.

[0012] Furthermore, a vertical adjustment screw and a horizontal adjustment screw are respectively provided on the top and side surfaces of the sight housing, which are used to abut against the top and side surfaces of the rear end of the cylindrical inner core; the outer surface of the front end of the cylindrical inner core is spherical, which can rotate relative to the spherical assembly of the corresponding cavity at the front end of the sight housing.

[0013] Furthermore, a laser module circuit board is fixed to the bottom surface of the laser module mounting part, located on the rear side of the groove.

[0014] The beneficial effects of this invention are: This invention integrates two functions (inner red dot and laser) into one, reducing the overall size. It also enables the laser module to move synchronously with the inner red dot, eliminating the need for an adjustment mechanism, making adjustment more convenient, and enhancing human-machine interface. The laser axis is very close to the red dot axis, reducing errors in multiple aiming baselines.

Detailed Implementation

[0026] The present invention will be further described below with reference to the embodiments. However, those skilled in the art will understand that the following embodiments are for illustrative purposes only and should not be considered as limiting the scope of the invention. Unless otherwise specified, specific conditions in the embodiments are performed under conventional conditions or conditions recommended by the manufacturer. Reagents or instruments used, unless otherwise specified, are all commercially available products. The specific embodiments described are only for explaining the principles of the invention and are not intended to limit the invention.

[0027] Figure 1 The image shows a laser assembly, including a base 1, which includes a front-side laser module mounting section 2. Figure 1 The inner part of the rectangular frame has two laser modules, the first laser module 3 and the second laser module 4, mounted side by side along its width (which can be combined). Figure 3(See attached image). It can achieve dual laser light sources, such as green laser and red laser, which can be selected according to actual needs. To facilitate installation and adjustment of the laser emission direction, this embodiment has a groove 5 extending along its width at the front end of the bottom of the laser module mounting part 2; an adjustment reference is provided at the rear end of the base 1. Figure 1 The screw hole 6 shown serves as a reference for subsequent left-right or up-down adjustment of the laser assembly. Furthermore, the two opposite outer surfaces 7 and 8 extending along their length on the base 1 are... Figure 3 The outer arch has an arc-shaped surface, which facilitates the adaptation of the arc shape of the mounting surface of the sight core during the adjustment of its laser emission direction.

[0028] Depend on Figure 1 It can also be seen that the base 1 further includes a cantilever portion 10, which extends backward and downward from the rear slope portion 9 of the laser module mounting portion 2 (i.e., the top surface of the rear end of the laser module mounting portion 2 is a slope), and the top surface of the cantilever portion 10 is coplanar with the top surface of the rear slope portion 9, forming a slope extending downward from front to back; and the top surface of the slope is provided with multiple horizontal grooves 11 that are parallel and evenly distributed along its length to eliminate stray light, which are mainly used to eliminate the interference of stray light from the surrounding environment, which is a common method; in order to achieve adjustment of the entire base 1, the adjustment reference provided in this embodiment is a screw hole 6 opened at the center of the rear end of the cantilever portion 10, which is then fixed by a screw 18 installed in the screw hole 6 (see Figure 6 Be prepared. And, by Figure 4 As can be seen, a laser module circuit board 13 is fixed on the bottom surface of the laser module mounting part 2 and is located on the rear side of the groove 5. It is electrically connected to the aforementioned first laser module 3 and second laser module 4. This is a conventional circuit design.

[0029] Based on the foregoing embodiments, this embodiment provides a Figure 5 The red dot sight shown, which includes the aforementioned laser assembly 17, includes a cylindrical inner core 15 with an objective lens assembly 14 mounted at the front end, and the laser assembly 17 is positioned... Figure 6 The bottom surface of the inner cavity of the cylindrical inner core 15 shown extends rearward from the inside of the objective lens assembly 14 along the length direction of the cylindrical inner core 15; and by means of Figure 7 As can be seen, a protrusion 16 that can be inserted into the groove 5 is provided on the front side of the bottom surface of the cylindrical inner core 15; and a through hole that is directly opposite to and coaxial with the screw hole 6 is provided on the rear side of the bottom surface of the cylindrical inner core 15, so as to allow for Figure 6 The fixing screw 18 shown passes through the hole from the bottom surface of the cylindrical inner core 15 and then engages with it. Figure 7 The screw hole 6 shown is threaded.

[0030] Depend on Figure 6As can be seen, the LED light source assembly 19 is fixed on the rear side of the bottom surface of the cylindrical inner core 15. The laser module mounting part 2 of the laser assembly 17 is equipped with a first laser module 3 and a second laser module 4 arranged side by side along its width direction. The emitted beams of the LED light source assembly 19, the first laser module 3 and the second laser module 4 are all projected onto the objective lens assembly 14 and reflected by the objective lens assembly 14 to form parallel reflected beams. In this way, the optical axes of the reflected beams of the LED light source assembly 19, the first laser module 3 and the second laser module 4 are parallel, achieving the effect of coaxial reflected light from the three light sources. It should also be noted that since the objective lens assembly 14 is existing technology, it has a semi-transparent and semi-reflective function, that is, the emitted beams of the LED light source assembly 19, the first laser module 3 and the second laser module 4 are partially projected onto the target through the objective lens assembly 14.

[0031] A mounting hole 20 is also provided on the bottom surface of the inner cavity of the cylindrical inner core 15 (for connection). Figure 7 As shown, the laser module circuit board 13 is used to place the laser assembly 17 into the cylindrical inner core 15 or to facilitate the assembly and disassembly of the laser module mounting part 2.

[0032] See you later Figure 5 As can be seen, a vertical adjustment screw 22 and a horizontal adjustment screw 23 are respectively provided on the top and side surfaces of the sight housing 21, which are used to abut against the rear end of the cylindrical inner core 15 (see...). Figure 10 The top and sides of the cylindrical inner core 15; and the outer surface 24 of the front end of the cylindrical inner core 15 is Figure 6 The spherical surface shown can rotate relative to the cavity at the front end of the corresponding sight housing 21. Specifically, by screwing in or out the vertical adjusting screw 22 and the horizontal adjusting screw 23, the vertical or horizontal angle of the cylindrical inner core 15 can be adjusted under the control of the outer surface 24 (spherical surface) at the front end of the cylindrical inner core 15, thereby adjusting the direction of the emitted light from the LED light source assembly 19 and the laser assembly 17.

[0033] Finally, it should be noted that the emitted light from the laser component 17 can also be adjusted by screwing in or out the fixing screw 18, and by adapting the groove 6 and the protrusion 16 (i.e., the protrusion 16 can swing left and right and up and down within the groove 5 under the guidance of the arc-shaped surface of its end face), thus achieving adjustment of the pitch angle and left and right angle of the laser component 17. This allows the optical axis of the dual laser emitted light from the laser component 17, namely the emitted light from the first laser module 3 and the second laser module 4, after reflection by the objective lens 14, to be aligned with... Figure 7 The light source of the LED light source assembly 19 shown is reflected by the objective lens 14 and the optical axis of the reflected light remains consistent, thus achieving the effect of a coaxial light source.
