Description

Technical Field

[0001] This utility model relates to the field of eyeglasses, and in particular to a liquid-filled zoom lens assembly and eyeglasses. Background Technology

[0002] Early myopia is mostly pseudomyopia, which can be corrected by reducing screen time. When teenagers engage in activities such as reading and writing at close range for extended periods, the ciliary muscles of the eyes remain in a state of tension, leading to accommodative spasm, which can easily cause myopia to worsen.

[0003] To treat pseudomyopia or slow the progression of myopia, fogging therapy can be used. This therapy involves wearing convex lenses to relax the eye muscles and relieve accommodative spasm caused by ciliary muscle tension. However, fogging therapy currently requires two pairs of glasses, and the user needs to frequently switch between prescription and fogging glasses depending on the situation, which is very inconvenient. Utility Model Content

[0004] The purpose of this invention is to address the deficiencies in the aforementioned technology by providing a liquid-filled zoom lens assembly and glasses that eliminate the need for two pairs of glasses when using fogging therapy to alleviate myopia, thus making it more convenient to use.

[0005] The purpose of this utility model is achieved as follows:

[0006] A first aspect of this application provides a liquid-filled zoom lens assembly, including a lens group and a frame connected to the lens group; wherein...

[0007] The lens assembly has a cavity shaped like a convex lens inside;

[0008] It also includes a liquid filling device, which includes a liquid tank, a gas tank, and a driving mechanism. The liquid tank and the gas tank are respectively connected to the cavity of the lens assembly. The driving mechanism is used to drive the liquid in the liquid tank or the gas in the gas tank into the cavity.

[0009] In the above scheme, when using the eyes for close-range work, the driving mechanism allows liquid from the liquid tank to flow into the cavity. Once filled with liquid, the cavity acts like a convex lens, providing a certain positive power for near vision. This reduces the prescription of the myopia glasses by a corresponding amount, helping the eyes relax and reducing excessive tension in the ciliary muscle, achieving the effect of fogging therapy. When using the eyes for distance work, the driving mechanism allows gas from the gas tank to enter the cavity, restoring the lens to its original power, achieving the effect of ordinary myopia glasses. This eliminates the need for frequent changes of myopia glasses and fogging glasses. Vision training can also be performed. By controlling the gas and liquid through the liquid filling device to present different powers in the glasses, the process of vision progressing from blurry to clear is achieved. This repeatedly contracts the ciliary muscle, exercising the eye muscles, increasing their strength, relieving eye fatigue, and thus preventing myopia.

[0010] In one possible implementation, the lens assembly includes a first concave lens and a second concave lens, the first concave lens and the second concave lens being respectively sealed to the lens frame, and a cavity shaped like a convex lens being provided between the first concave lens and the second concave lens.

[0011] In one possible implementation, the bottom of the lens assembly on the side away from the bridge of the nose is provided with a liquid passage hole, one end of which is connected to the liquid tank and the other end of which is connected to the cavity;

[0012] The lens assembly has a vent at the top near the bridge of the nose, with one end of the vent connected to the gas tank and the other end connected to the cavity.

[0013] In one possible implementation, a pressure valve is provided at the connection between the vent hole and the liquid passage and the cavity.

[0014] In one possible implementation, the liquid inlet is connected to the liquid tank via a first conduit; the vent is connected to the gas tank via a second conduit.

[0015] In one possible implementation, the drive mechanism includes a first piston and a second piston, the first piston being placed inside the liquid tank and the second piston being placed inside the gas tank;

[0016] The second piston includes a base and a plug body; wherein,

[0017] The plug is slidably sealed to the gas tank, the base is clearance-fitted to the gas tank, and the base and the plug are connected by an elastic element.

[0018] In one possible implementation, the drive mechanism further includes a rack and a drive gear meshing with the rack; wherein,

[0019] The rack is connected to the first piston and the second piston at its two ends, respectively;

[0020] It also includes a motor, which is connected to the gear.

[0021] In one possible implementation, the output end of the motor is connected to a first bevel gear; a second bevel gear is connected to one side of the drive gear.

[0022] The first bevel gear meshes with the second bevel gear.

[0023] A second aspect of this application provides eyeglasses comprising the liquid-filled zoom lens assembly described above.

[0024] In one possible implementation, the mirror also includes a crossbeam and temples rotatably connected to both sides of the crossbeam.

[0025] The crossbeam is provided with a nose pad in the middle, and liquid-filled zoom lens assemblies are mirror-mounted on both sides of the nose pad;

[0026] The liquid filling device for the liquid-filled zoom lens assembly is located inside the crossbeam. Attached Figure Description

[0033] This application provides a liquid-filled zoom lens assembly and eyeglasses. A cavity shaped like a convex lens is provided inside the lens assembly, and a liquid tank and a gas tank are connected to the cavity. A drive mechanism controls the flow of liquid from the liquid tank or gas from the gas tank into the cavity of the lens assembly. The eyeglasses display different prescriptions depending on whether the cavity contains gas or liquid, thus adapting to the different prescription needs for near and far vision, eliminating the need to change eyeglasses.

[0034] To facilitate understanding of the technical solution of this application, its application scenarios are described below: The liquid-filled zoom lens assembly in this application is mainly suitable for situations in fogging therapy where the lens power needs to be changed for near and far vision. Traditional solutions require frequent changes between prescription glasses and fogging glasses to relax eye muscles, relieve accommodative spasm caused by ciliary muscle tension, and alleviate myopia, depending on the specific visual needs. However, in this application, the cavity within the lens assembly can be filled with liquid to change the power, eliminating the need to change glasses for different visual needs.

[0035] The following description, in conjunction with the accompanying drawings, further illustrates this implementation case:

[0036] Depend on Figure 1 — Figure 6 As can be seen, the first aspect of this application provides a liquid-filled zoom lens assembly, including a lens group 1 and a lens frame 2 connected to the lens group 1; wherein, the lens group 1 has a cavity 11 shaped like a convex lens inside. It should be noted that, in this embodiment, the lens group 1 can be a double lens, that is, by setting a gap between two lenses, the gap being shaped like a convex lens, in which case the two lenses can be sealed and connected to the lens frame 2 around their perimeter; or it can be a single lens, with a cavity 11 shaped like a convex lens set inside the lens through a manufacturing process.

[0037] To achieve the purpose of changing the prescription by filling the cavity 11 with liquid or gas, this application also includes a liquid filling device. The liquid filling device includes a liquid tank 3, a gas tank 4, and a driving mechanism 5. The liquid tank 3 is used to store liquid, while the gas tank 4 is used to store gas. As an example, the liquid in this embodiment can be glycerol solvent, and the gas is an inert gas, as glycerol solvent and inert gas have relatively stable physical properties. Further, the liquid tank 3 and the gas tank 4 are respectively connected to the cavity 11 of the lens assembly 1, and the driving mechanism 5 is used to drive the liquid in the liquid tank 3 or the gas in the gas tank 4 into the cavity 11.

[0038] It should be noted that the driving mechanism 5 in this application can adopt various driving forms. For example, the gas tank 4 and the liquid tank 3 are supported by elastic materials, and the driving mechanism 5 compresses the tank bodies of the gas tank 4 and the liquid tank 3, causing the tank bodies to deform under pressure, thereby forcing the liquid or gas into the cavity 11. Alternatively, the driving mechanism 5 can directly compress the gas and liquid inside the gas tank 4 and the liquid tank 3, causing them to fill the cavity 11. It should be understood that in this embodiment, the volumes of the liquid tank 3 and the gas tank 4 are both larger than the volume of the cavity 11, so that the liquid or gas can completely fill the cavity 11.

[0039] In the above scheme, when using the eyes for close-range work, the driving mechanism 5 causes the liquid in the liquid tank 3 to flow into the cavity 11. After the cavity 11 is filled with liquid, it acts like a convex lens, providing a certain positive power when looking at near objects. This reduces the fixed power of the myopia glasses, helping the eyes relax and reducing excessive tension of the ciliary muscle, achieving the effect of fogging therapy. When using the eyes for distance work, the driving mechanism 5 causes the gas in the gas tank 4 to enter the cavity 11, restoring the lens to its original power, achieving the effect of ordinary myopia glasses. This eliminates the need for frequent replacement of myopia glasses and fogging glasses.

[0040] In one optional implementation, for ease of manufacturing, the lens assembly 1 in this embodiment adopts a split structure, referring to... Figure 4The lens includes a first concave lens 12 and a second concave lens 13, which are respectively sealed to the frame 2. A cavity 11 in the shape of a convex lens is provided between the first concave lens 12 and the second concave lens 13. It should be understood that the size of the cavity 11 can be determined according to the actual prescription of the eyes.

[0041] In one alternative implementation, refer to Figure 3 The lens assembly 1 has a liquid inlet 14 at its bottom on the side away from the bridge of the nose. One end of the liquid inlet 14 is connected to the liquid tank 3, and the other end is connected to the cavity 11. The lens assembly 1 has a vent 15 at its top on the side near the bridge of the nose. One end of the vent 15 is connected to the gas tank 4, and the other end is connected to the cavity 11. In other words, this application places the liquid inlet 14 at the bottom of the cavity 11 and the vent 15 at the top of the cavity 11, so that the liquid enters from the bottom of the cavity 11. This ensures that the liquid can completely expel the gas during filling, preventing air bubbles from remaining in the cavity 11 after filling, which would affect the user experience.

[0042] In one alternative implementation, refer to Figure 3 A pressure valve 6 is provided at the connection between the vent 15 and the liquid inlet 14 and the cavity 11. The function of the pressure valve 6 is to prevent liquid or gas from flowing out when the device is inverted. The working pressure during liquid or gas filling will exceed the threshold of the pressure valve 6, but will not affect normal operation.

[0043] In order to enable the flow of liquid or gas between the liquid tank 3, the gas tank 4 and the cavity 11, the liquid passage 14 in this application is connected to the liquid tank 3 through the first conduit 16; the vent 15 is connected to the gas tank 4 through the second conduit 17.

[0044] It should be noted that, in this application, the first conduit 16 and the second conduit 17 can be placed outside the frame 2 or inside the frame 2.

[0045] In one alternative implementation, refer to Figure 3 The driving mechanism 5 includes a first piston 51 and a second piston 52. The first piston 51 is placed inside the liquid tank 3, and the second piston 52 is placed inside the gas tank 4. In this application, the first piston 51 squeezes the liquid inside the liquid tank 3, causing the liquid inside the liquid tank 3 to enter the cavity 11. The structure of the first piston 51 is the same as that of commercially available pistons, and it uses an elastic material such as rubber to slide and seal with the liquid tank 3.

[0046] It should be noted that the second piston 52 in this application includes a base 521 and a plug body 522; wherein, the plug body 522 is slidably and sealingly connected to the gas tank 4, and the plug body 522 may be made of materials such as rubber. The base 521 and the gas tank 4 are fitted with a clearance fit, and the base 521 and the plug body 522 are connected by an elastic element 523. Because the base 521 and the inner wall of the gas tank 4 are fitted with a clearance fit, the base 521 and the inner wall of the gas tank 4 are permeable. The base 521 and the plug body 522 are elastically connected. When there is a temperature change, and the gas expands or contracts, the position of the base 521 is mainly controlled by the drive mechanism 5, so the position of the base 521 remains stationary. At this time, the plug body 522 overcomes the elastic force of the elastic element 523 and can automatically displace relative to the base 521 to compensate for the expansion or contraction of the gas.

[0047] As an example, the elastic element 523 in the second piston 52 can be a wire spring, disc spring, etc.

[0048] In one alternative implementation, refer to Figures 1-3 The drive mechanism 5 also includes a rack 53 and a drive gear 54 meshing with the rack 53. In this embodiment, to ensure the synchronous flow of liquid and gas, the two ends of the rack 53 are respectively connected to the first piston 51 and the second piston 52. When the rack 53 moves toward the first piston 51, the first piston 51 compresses the liquid in the liquid tank 3, causing the liquid to enter the cavity 11. At the same time, the second piston 52 also moves toward the first piston 51, increasing the cavity between the second piston 52 and the gas tank 4, allowing liquid to enter the cavity 11 while gas in the cavity 11 enters the gas tank 4. When the rack 53 moves toward the second piston 52, the gas in the gas tank 4 is pressurized and enters the cavity 11, forcing the liquid in the cavity 11 into the liquid tank 3. While the second piston 52 compresses the gas in the gas tank 4, the cavity between the first piston 51 and the liquid tank 3 increases, facilitating the entry of liquid into the liquid tank 3.

[0049] To drive the movement of the rack 53, this application also includes a motor 55, which is connected to the gear. When the motor 55 rotates forward, it drives the rack 53 to move closer to or further away from the first piston 51. When the motor 55 rotates in reverse, it drives the rack 53 to move in the opposite direction to the forward rotation.

[0050] In one alternative implementation, refer to Figure 2To reduce the overall size of the drive mechanism 5, the output end of the motor 55 is connected to a first bevel gear 56, and one side of the drive gear 54 is connected to a second bevel gear 57. The first bevel gear 56 meshes with the second bevel gear 57. Through the cooperation of the first bevel gear 56 and the second bevel gear 57, the axis of the motor 55 is in the same direction as the axis of the liquid tank 3, and the two are in a similar folded state, which effectively reduces the size of the drive mechanism 5.

[0051] A second aspect of this application provides eyeglasses, as shown in [reference]. Figure 5 , Figure 6 The glasses include one liquid-filled zoom lens assembly as described above.

[0052] In one alternative implementation, refer to Figure 6 The application also includes a crossbeam 71 and temples 72 rotatably connected to both sides of the crossbeam 71. A nose pad 73 is provided in the middle of the crossbeam 71, and a liquid-filled zoom lens assembly is mirrored on both sides of the nose pad 73. The liquid filling device of the liquid-filled zoom lens assembly is located inside the crossbeam 71, ensuring the simplicity of the glasses' appearance.

[0053] It should be understood that the glasses described in this application also include components such as battery 83, control button 82, and circuit board 81. In order to ensure that the glasses have a simple and beautiful appearance, in this embodiment, battery 83 and circuit board 81 are also set inside the crossbeam 71, and control button 82 can be set in the middle or side of the crossbeam 71.
