Description

Technical Field

[0001] This utility model relates to the field of aiming scopes, specifically to an auxiliary display structure that can be used in aiming scopes and an aiming scope. Background Technology

[0002] Some existing sights, in order to display auxiliary information, place the display screen on one side of the second focal plane and use two prisms arranged in the optical path. These prisms are tilted towards the principal optical axis, with a reflective film placed between them. The reflective film reflects light of a specific wavelength while allowing other wavelengths to pass through. In other words, the reflective film reflects the light emitted from the display screen to the target and allows light from the objective lens to pass through and reach the target. While this sight can display auxiliary information, the displayed information is presented across the entire field of view, which may obstruct some light. Furthermore, the prism configuration not only increases the weight of the sight but also increases assembly difficulty and cost. Utility Model Content

[0003] The primary objective of this invention is to provide an auxiliary display structure for a scope that is simple in structure, easy to assemble, and low in cost.

[0004] The second objective of this invention is to provide a sight that includes the aforementioned auxiliary display structure that can be used in a sight.

[0005] To achieve the aforementioned first objective, this utility model provides a sight with auxiliary display, comprising an inverted mirror tube, a display screen, a display screen base, a reticle, and a reflector. The display screen base is disposed at the eye-viewing end of the inverted mirror tube, and the display screen is disposed on the display screen base with its display surface facing the axis of the display screen base. The reticle is disposed inside the display screen base, and the reticle surface of the reticle coincides with the second focal plane of the sight. Visible light from the objective end of the inverted mirror tube can pass through the reticle to form the main field of view. The reflector is disposed on the display screen base and is obliquely disposed between the reticle and the display screen. The reflector can reflect the light emitted by the display screen to the target, forming an auxiliary display area, which is disposed on one side of the main field of view.

[0006] As can be seen from the above solution, by setting an auxiliary display area on one side of the main field of view, auxiliary information can be displayed without obstructing the light from the main field of view. By setting a reflector to reflect the light from the display screen to the target, it is convenient for the user to view relevant auxiliary information while observing the main field of view, which is beneficial to improving aiming clarity and accuracy, and is beneficial to the user's aiming operation. By setting the reticle in the second focal plane, the processing requirements are lower, the cost is lower, the structure is simpler, and it is easier to assemble than setting the reticle in the first focal plane. This utility model achieves image coupling display between the display screen and the reticle by synergistically arranging the display screen, reflector, and reticle, replacing the large and bulky beam splitter prism. Without changing the basic structure of the traditional sight, it achieves the display of auxiliary information at a lower cost and with a simpler assembly method, and improves the user experience.

[0007] A further proposed solution is to position the auxiliary display area above the main field of view, with the lower edge of the auxiliary display area higher than the center line of the main field of view.

[0008] A further proposed solution is to have the display screen perpendicular to the second focal plane, and the reflector intersecting the second focal plane at a preset angle of 45°.

[0009] As can be seen from the above scheme, the above settings enable the reflector to clearly reflect the content of the display screen as a virtual image to the target.

[0010] A further option is to house the reticle within the display mount; the auxiliary display structure for the scope also includes a reticle frame connected to the display mount to secure the reticle within the mount.

[0011] As can be seen from the above solution, by fixing the reticle, reflector, and display screen together in the display screen base, it is convenient to assemble and to position the three components, ensuring that the virtual image of the display screen can be accurately and clearly reflected.

[0012] A further proposed solution is that the display stand is provided with a center hole, a first mounting slot, a second mounting slot, and a third mounting slot. The first mounting slot is located at the end of the center hole facing away from the target and is connected to the center hole. The second mounting slot is located on the outside of the center hole. The third mounting slot is obliquely located between the second mounting slot and the center hole, and the third mounting slot is connected to both the second mounting slot and the center hole.

[0013] A further proposed solution is to place the reticle in the first mounting groove, with a first straight section on one side of the reticle, and the first straight section being arranged close to the reflector.

[0014] As can be seen from the above scheme, the above settings can avoid interference between the reflector and the reticle, and make it easier to install the reflector; on the other hand, it can make the virtual image formed by the display screen fall on the position corresponding to the cut-off part of the reticle.

[0015] A further improvement is that the display base is also provided with a protrusion; the reticle frame includes a sleeve part and a flat part, the flat part is provided with a second straight part, and the protrusion can extend to the second straight part; the auxiliary display structure that can be used for the scope also includes an adjustment ring, one end of which is inserted into the end of the inverted mirror tube near the eye, the depth of the adjustment ring inserted into the inverted mirror tube is adjustable, and the other end of the adjustment ring is sleeved on the outside of the sleeve part and abuts against the protrusion.

[0016] As can be seen from the above scheme, the above settings facilitate the adjustment of the axial distance between the inverted lens tube and the reticle, ensuring that the second focal plane of the scope coincides with the reticle surface.

[0017] Another further solution is to connect the adjusting ring to the inverted mirror tube thread.

[0018] A further option is to use a reflector or a reflective film as the reflector.

[0019] To achieve the second objective mentioned above, the aiming scope provided by this utility model includes the aforementioned auxiliary display structure that can be used in the aiming scope. Attached Figure Description
