Description

Technical Field

[0001] The embodiments of the present application belong to the field of AR technology, and in particular, relate to AR glasses with vision correction function. Background Art

[0002] At present, the AR glasses market has broad prospects. Optical waveguide lenses are considered to be the mainstream technology of the future due to their advantages of light weight and high light transmittance. However, AR glasses are not friendly to people with refractive errors, and usually require additional configuration and design for vision correction. Optical waveguide AR glasses generally have three vision correction methods: the first is to watch directly with myopia glasses. This method will cause interference with structural parts, discomfort to wear, and it is difficult to adjust to the best viewing effect, making it impossible to wear for a long time or even all day; the second is to add an additional adsorption myopia lens. This method still separates the glasses from the lens, affecting the appearance; the third is to directly fit the optical waveguide lens with the plano-concave or plano-convex lens. This method requires the production of glasses with different degrees at the factory, and the difference in degrees between the left and right eyes must also be considered. If astigmatism is taken into account, more degree combinations are required, corresponding to a large number of glasses versions, which is not suitable for mass production. Summary of the invention

[0037] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application. Embodiment 1

[0038] like Figure 1 As shown, the embodiment of the present application provides an optical waveguide lens with a vision correction function. The optical waveguide lens is a lens with a planar structure, generally made of high-refractive index glass or resin material; because AR glasses need to view displayed content and the real world at the same time, therefore, when solving the vision correction problem of AR glasses, it is necessary to set the corrective lens 2 between the optical waveguide lens 1 and the human eye;

[0039] The embodiment of the present application uses electronic control to inject liquid into the microcavity.

[0040] The embodiment of the present application provides an optical waveguide lens with a vision correction function, including a correction lens 2, an optical waveguide lens 1, a power mechanism 5, a first liquid storage pipe 3, a second liquid storage pipe 4, a solenoid valve 7 and a diopter display device 6;

[0041] The corrective lens 2 is arranged between the optical waveguide lens 1 and the human eye;

[0042] The corrective lens 2 includes a microcavity, in which a liquid is arranged, and a plurality of liquids are isolated by an inert gas; the refractive power of the optical waveguide lens 1 is adjusted by adjusting the type of liquid arranged in the microcavity, and in addition, only gas may be arranged in the microcavity, and the focal length of the optical waveguide lens 1 is determined by the gas.

[0043] In the embodiment of the present application, the cross section of the microcavity is the same as the cross section of the corresponding optical waveguide lens 1 , and an air gap exists between the microcavity and the optical waveguide lens 1 .

[0044] The power mechanism 5 is connected to the first liquid storage pipe 3, and the first liquid storage pipe 3 and the second liquid storage pipe 4 are both connected to the microcavity; different liquids are arranged in the first liquid storage pipe 3, and the different liquids are separated by gas, and the gas in the first liquid storage pipe 3 can be the same or different, and the gas in the second liquid storage pipe 4 can be the same.

[0045] The power mechanism 5 drives the liquid in the first liquid storage pipe 3 to flow into the microcavity to replace the original liquid in the microcavity and discharge the original liquid in the microcavity to the second liquid storage pipe 4; or the power mechanism 5 sucks the liquid in the second liquid storage pipe 4 into the microcavity and discharges the original liquid in the microcavity to the first liquid storage pipe 3, and the solenoid valve 7 is connected to the second liquid storage pipe 4. The diopter display device 6 is connected to the power mechanism 5 and is used to display the diopter corresponding to the current output power of the power mechanism 5.

[0046] In the embodiment of the present application, the first liquid storage pipe 3 and the second liquid storage pipe 4 are arranged in a spiral or bow-shaped winding manner to increase the length and save space; the first liquid storage pipe 3 and the second liquid storage pipe 4 store liquids of various refractive indices in the form of liquid with a refractive index n1-inert gas (or nitrogen, etc.)-liquid with a refractive index n2-air (or nitrogen, etc.) in alternation; when the power mechanism 5 and the electronic valve are opened at the same time, the liquid in the first liquid storage pipe 3, the second liquid storage pipe 4 and the microcavity can be driven to flow, so that the liquid in the microcavity is replaced by controlling the voltage of the power mechanism 5; since the microcavity has a Fresnel-type microstructure surface, different liquids can be matched with the Fresnel structure to produce different optical focal lengths, that is, different diopter adjustments can be achieved; through calibration, the flow rate of the liquid and the opening time of the power mechanism 5 are matched with the type of liquid in the microcavity, and the type of liquid corresponds to the optical focal length, so it is displayed in the form of diopter on the diopter display device 6 through data conversion.

[0047] In the embodiment of the present application, the first liquid storage pipe 3 and the second liquid storage pipe 4 may be hoses made of Teflon, silicone and other materials, and the first liquid storage pipe 3 and the second liquid storage pipe 4 may be or other liquids that are not easy to react chemically with the first liquid storage pipe 3, the second liquid storage pipe 4, and the microcavity material. The inert gas in the embodiment of the present application is nitrogen or an inert gas of a group 0 element or a gas that is insoluble in water, wherein the group 0 element is an IUPAC group 18 element, including helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) and austenite (Og), which can emit light when powered on, and because the outermost electrons are fully arranged, the chemical properties are generally stable and not easy to react chemically.

[0048] In the embodiment of the present application, the power mechanism 5 and the solenoid valve 7 need to be triggered synchronously, and the power mechanism 5 can realize positive pressure and negative pressure, that is, the liquid in the first liquid storage pipe 3 can be pressed into the microcavity, and the original liquid in the microcavity can be discharged to the second liquid storage pipe 4; the liquid in the second liquid storage pipe 4 can also be sucked into the microcavity, and the original liquid in the microcavity can be discharged to the liquid storage pipe of the first liquid storage pipe 3.

[0049] like Figure 2 and Figure 3 As shown, in the embodiment of the present application, the micro-chamber includes a first shell 23, a spiral micro-channel 24, a first liquid inlet 21 and a first liquid outlet 22;

[0050] The spiral microchannel 24 is disposed in the first housing 23, and the first liquid inlet 21 and the first liquid outlet 22 are respectively connected to the spiral microchannel 24;

[0051] After the liquid in the microcavity flows into the spiral microchannel 24 through the first liquid inlet 21, the power mechanism 5 drives the multiple liquids to flow in the spiral microchannel 24 and flow out through the first liquid outlet 22. The liquid flows in the spiral microchannel 24 according to the flow path 25.

[0052] In the embodiments of the present application, the thickness of the liquid in the microcavity is several microns to several hundred microns; the interior of the front shell of the microcavity has a Fresnel surface, which can be designed to have different focal lengths, which can be positive focal lengths or negative focal lengths; taking the structure of the surface of the front shell of the microcavity as a positive focal length as an example, when the refractive index of the liquid is smaller than the refractive index of the surface of the front shell of the microcavity, the entire microcavity corresponds to a positive focal length. At this time, the smaller the refractive index of the liquid, the shorter the focal length; when the refractive index of the liquid is greater than the refractive index of the surface of the front shell of the microcavity, the entire microcavity corresponds to a negative focal length. At this time, the larger the refractive index of the liquid, the shorter the focal length; when the refractive index of the liquid is equal to the refractive index of the surface of the front shell of the microcavity, the entire microcavity is equivalent to a flat optical structure with an infinite focal length.

[0053] A spiral microchannel 24 is provided in the first shell 23, which can allow the liquid to flow from the first liquid inlet 21 to the first liquid outlet 22, and vice versa, to ensure that the liquid in the first liquid storage pipe 3 or the second liquid storage pipe 4 will not be interrupted when entering the microcavity, or even form bubbles in the end, and at the same time ensure that the gas between different liquids in the first liquid storage pipe 3 or the second liquid storage pipe 4 can smoothly flow out of the liquid that is already in the microcavity.

[0054] In the embodiment of the present application, the power mechanism 5 is a manual piston tube or other micro-fluidic pumps such as a piezoelectric pump. Embodiment 2

[0055] like Figure 4 As shown, the difference between the second embodiment and the first embodiment is that the AR glasses further include a power mechanism 5, a first liquid storage pipe 3 and a second liquid storage pipe 4; but there is no solenoid valve.

[0056] The power mechanism is in communication with the first liquid storage pipe 3, the first liquid storage pipe 3 and the second liquid storage pipe 4 are both in communication with the microcavity, the second liquid storage pipe 4 is also connected to the power mechanism 5, different liquids are arranged in the first liquid storage pipe 3, and the different liquids are separated by gas;

[0057] The power mechanism 5 is used to drive the liquid in the first liquid storage pipe 3 to flow into the microcavity to replace the original liquid in the microcavity, and discharge the original liquid in the microcavity to the second liquid storage pipe 4; or the power mechanism 5 is used to suck the liquid in the second liquid storage pipe 4 into the microcavity, and discharge the original liquid in the microcavity to the first liquid storage pipe 3.

[0058] In this embodiment, one end of the end of the second liquid storage pipe 4 (connected to the solenoid valve 7 in the first embodiment) is connected to one end of the power mechanism 5 to form a closed-loop structure, so that the flow of liquid in the microcavity and the liquid storage tube can be realized through the power mechanism 5, so as to achieve the effect of switching the liquid in the first liquid storage pipe 3 and the second liquid storage pipe 4 and changing the focal length. The power mechanism 5 in this embodiment can be a one-way pressure pump. Embodiment 3

[0059] It should be noted that the difference between the third embodiment and the first or second embodiment is that the microcavity structure is different and the method of injecting liquid is different.

[0060] In the embodiments of the present application, Figure 5 As shown, the microcavity includes a second shell 27, a first exhaust port 26 and a second liquid inlet 29; the first exhaust port 26 and the second liquid inlet 29 are respectively connected to the second shell 27. In this third embodiment, no isolation member is provided in the microcavity, so liquid 28 is stored in the microcavity.

[0061] In the embodiments of the present application, as long as liquids with different refractive indices can be injected into the microcavity, they all fall within the protection scope of the embodiments of the present application. That is to say, if a non-electronic control method is adopted, such as injecting liquid into the microcavity through manual adjustment, the AR glasses will provide users with a plurality of first liquid storage pipes 3 and second liquid storage pipes 4 corresponding to multiple refractive powers when leaving the factory. The user can inject the liquid corresponding to the user's own refractive power from the second liquid inlet 29. A detachable sealing plug is provided on the microcavity to ensure that the microcavity can be sealed after being filled with liquid; the user can also replace the liquid by himself to adjust the refractive power; in this case, the microcavity does not require an intra-cavity partition. When injecting liquid, it is recommended to slowly inject from the second liquid inlet 29 at the bottom to prevent bubbles, and also draw out from the second liquid inlet 29 at the bottom when discharging the liquid to prevent droplets from remaining. Embodiment 4

[0062] like Figure 6 As shown, the difference between the fourth embodiment and the third embodiment is that the microcavity structure is different.

[0063] The micro-chamber comprises a third shell 35, a second exhaust port 31, a third exhaust port 30, a third liquid inlet 36, a fourth liquid inlet 37 and an isolating member 33; the isolating member 33 is disposed in the third shell 35 to divide the third shell 35 into a first chamber 32 and a second chamber 34;

[0064] The second exhaust port 31 and the third liquid inlet 36 are respectively communicated with the first chamber 32 , and the third exhaust port 30 and the fourth liquid inlet 37 are respectively communicated with the second chamber 34 .

[0065] The surface of the isolation member 33 can be convex or concave. The concave surface mainly corresponds to a concave lens, and the convex surface corresponds to a convex lens. Similarly, only one cavity can be retained, but the ability to adjust the diopter is reduced. The specific method of including one cavity can be: not using one of the cavities, or making the hollow of one of the cavities solid, so that the other cavity cannot retain liquid.

[0066] The optical waveguide lens of the fourth embodiment has a better imaging effect than that of the third embodiment.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
