Detailed Implementation

[0038] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] like Figure 1 As shown, this utility model provides eyeglasses with adjustable liquid lenses, capable of adjusting the focal length of the lenses according to the position of the observed object. The eyeglasses include: a frame assembly, two lens assemblies, and a drive assembly. The frame assembly provides support for easy wear, and the two lens assemblies are symmetrically arranged on the frame assembly. The drive assembly is fixed to the frame assembly. The lens assemblies and the drive assembly work together to adjust the power of the lens assemblies.

[0042] like Figure 1 and Figure 2 As shown, the frame assembly includes: a frame 5 and two temples 6. The frame 5 provides support for the drive assembly and the lens assembly. The two temples 6 are symmetrically connected to both ends of the frame 5 to facilitate the user wearing the glasses.

[0043] like Figure 2 and Figure 4 As shown, each lens assembly includes: two protective layer lenses 9, a main lens 8, a flexible lens 7, and a frame 4. Figure 3As shown, the frame 4 is fixed to the eyeglass frame 5, and four fixing grooves 11 are provided parallel to each other on its inner wall. The fixing grooves 11 are used to fix the protective layer lens 9, the main lens 8, and the flexible lens 7. Figure 4 As shown, the main lens 8 is a non-prescription lens, fixed in the middle of the frame 4, with its edge fixed in a fixing groove 11 in the middle of the inner wall of the frame 4, providing support for the frame 4. The flexible lens 7 is a double-layer structure (including a first layer and a second layer) made of a stretchable transparent material, with a liquid transparent medium filling the space between the two layers. The flexible lens 7 is disposed between the main lens 8 and a protective layer lens 9, fixed in another fixing groove 11 in the middle of the inner wall of the frame 4, and has several focal length adjustment components evenly distributed along its edge. The thickness of the edge of the flexible lens 7 is adjusted by these focal length adjustment components, thereby adjusting the focal length of the flexible lens 7. The other protective layer lens 9 is disposed on the other side of the main lens 8. Therefore, the two protective layer lenses 9 are respectively disposed on two sides of the frame 4, with their edges placed in two fixing grooves 11 on the outer side of the inner wall of the frame 4, sealing both sides of the frame 4 and protecting the flexible lens 7 and the main lens 8.

[0044] Specifically, such as Figure 5 As shown, each of the focal length adjustment components includes: a first fixed rod 12, a second fixed rod 13, a sliding rod 14, and a motor. See also... Figure 5 A focal length adjustment assembly is disposed on the left and right sides of the flexible lens 7. The sliding rod 14 is fixed in the fixing groove 11 for mounting the flexible lens 7, and its surface is provided with a sliding groove perpendicular to the surface of the flexible lens 7. A first fixing rod 12 and a second fixing rod 13 are symmetrically fixed at the surface edges of the first and second layers of the flexible lens 7; the first fixing rod 12 is fixed to one side of the sliding groove, and the second fixing rod 13 can slide within the sliding groove. A motor is mounted on the sliding rod 14, and its output end is connected to the second fixing rod 13, driving the second fixing rod 13 to move along the sliding groove, adjusting the distance between the second fixing rod 13 and the first fixing rod 12. Since the first and second fixing rods are respectively fixed to the double-layer structure of the flexible lens, when the distance between the first and second fixing rods changes, the distance between the first and second layers of the flexible lens changes, thereby changing the thickness of the flexible lens 7.

[0045] Furthermore, the motors in all the focus adjustment components installed on the flexible lens move synchronously, so that the thickness at the edge of the flexible lens 7 remains consistent.

[0046] In a preferred embodiment, such as Figure 3As shown, the inner wall of the lens frame 4 has several grooves 15 at the outer edge of the fixing groove 11 for fixing the flexible lens 7; and each groove 15 is perpendicular to the fixing groove 11 and communicates with the inside of the fixing groove 11. Its size matches the motor in the focal length adjustment assembly and is used to place the motor so that the motor is locked on the inner wall of the lens frame 4.

[0047] Furthermore, to reduce the number of focal length adjustment components used in the long side direction (i.e., the upper and lower sides of the flexible lens) of the flexible component 7, and thus reduce the number of motors controlling the thickness of the flexible lens 7, several first auxiliary fixing rods 19, several second auxiliary fixing rods 18, a first connecting rod 17, and a second connecting rod 16 are added to the focal length adjustment component in each long side direction of the flexible component 7. Specifically, as shown... Figure 5 As shown, each first auxiliary fixing rod 19 is arranged side by side with the first fixing rod 12; each second auxiliary fixing rod 18 is arranged side by side with the second fixing rod 13; and each first auxiliary fixing rod 19 and the corresponding second auxiliary fixing rod 18 are symmetrically fixed to the first layer structure surface and the second layer structure surface of the flexible lens. The first connecting rod 17 connects all the first auxiliary fixing rods 19 and the first fixing rod 12 along the long side of one side of the flexible component 7, and the first connecting rod 17 is fixed to one side of the sliding groove of the sliding rod 14; the second connecting rod 16 connects all the second auxiliary fixing rods 18 and the second fixing rod 13 along the long side of one side of the flexible component 7, and the second connecting rod 16 is disposed in the sliding groove and can move along the sliding groove; the second connecting rod 16 is connected to the output end of the motor, and the motor drives the second connecting rod 16 to slide along the sliding groove, so that the second connecting rod 16 moves relative to the first connecting rod 17, thereby driving the relative movement of the second fixing rod 13 and the first fixing rod 12, and the relative movement of the second auxiliary fixing rod 18 and the first auxiliary fixing rod 19, so that the distance between the first layer structure and the second layer structure of the flexible lens 7 changes, thereby changing the thickness of the flexible lens 7. At this time, when the focal length adjustment component is installed on one long side of the flexible lens 7, only one motor is needed to control the thickness of the flexible lens 7 on that side.

[0048] Specifically, both the protective layer lens 9 and the main lens 8 are made of transparent material.

[0049] Furthermore, such as Figure 2 As shown, the frame 5 is provided with a storage slot 3 for storing a transparent medium; as Figure 3 As shown, the fixing groove 11 on the frame 4 with the flexible lens 7 is provided with a connecting hole 10, which connects the transparent medium inside the flexible lens 7 with the internal space of the storage groove 3.

[0050] The driving component includes a liquid pump. The liquid pump is disposed on the connection hole 10 on the lens frame 4 and is used to control the content of the transparent medium inside the flexible lens 7, thereby adjusting the focal length of the flexible lens 7.

[0051] Regarding the transformation of the flexible lens 7 between a concave and convex lens, when the flexible lens 7 transforms from a convex lens to a concave lens, the distance between the first fixing rod 12 and the second fixing rod 13 is increased by controlling the operation of the motor in the focal length adjustment assembly. This increases the distance between the first and second layers of the flexible lens 7, thereby increasing the thickness at the edge of the flexible lens 7, making the thickness at the edge greater than the thickness in the middle of the flexible lens 7. Then, the content of the transparent medium inside the flexible lens 7 is adjusted by a liquid pump, changing the focal length of the concave lens of the flexible lens 7. When the flexible lens 7 transforms from a concave lens to a convex lens, the distance between the first fixing rod 12 and the second fixing rod 13 is decreased by controlling the operation of the motor in the focal length adjustment assembly. This decreases the distance between the first and second layers of the flexible lens 7, thereby reducing the thickness at the edge of the flexible lens 7, making the thickness at the edge less than the thickness in the middle of the flexible lens 7. Then, the content of the transparent medium inside the flexible lens 7 is adjusted by a liquid pump, changing the focal length of the convex lens of the flexible lens 7, thus changing the power of the flexible lens 7.

[0052] Example 1

[0053] To make it easier for users to wear the glasses, the glasses in this embodiment can intelligently adjust the focal length of the flexible lens 7.

[0054] like Figure 1 and Figure 2 As shown, the glasses also include a distance measuring component. The distance measuring component includes a laser rangefinder 1, which is mounted on the frame 5 and is capable of measuring the distance between the frame 5 and the target object, and using this distance as distance information.

[0055] like Figure 2 As shown, the driving component further includes a controller 2. The controller 2 is mounted on the frame 5 and can store lens parameters including the distance between the frame 5 and the target object, the corresponding thickness of the flexible lens 7, and the content of the transparent medium in the flexible lens 7. The controller 2 transmits signals with the motor, laser rangefinder 1, and liquid pump of the focus adjustment component. It can receive distance information sent by the laser rangefinder 1 and send the thickness of the flexible lens 7 and the content of the transparent medium matching the distance information to the motor and liquid pump of the focus adjustment component. This drives the motor of the focus adjustment component to change the thickness of the flexible lens 7 and simultaneously drives the liquid pump to change the content of the transparent medium in the flexible lens 7, thereby changing the focal length of the flexible lens 7.

[0056] In a preferred embodiment, the lens parameters stored in the controller 2 can be configured according to the user's needs.

[0057] When users with both myopia and presbyopia use the glasses of this invention, the laser rangefinder measures the distance between the frame 5 and the target object to generate distance information, which is then sent to the controller 2. The controller 2 sends the thickness of the flexible lens 7 and the content of the transparent medium, which match the distance information, to the motor and the pump of the focus adjustment assembly. This drives the motor in the focus adjustment assembly to adjust the distance between the first fixing rod 12 and the second fixing rod 13, thereby changing the thickness of the flexible lens 7. The pump also drives the liquid pump to change the content of the transparent medium inside the flexible lens 7, thereby changing the focal length of the flexible lens 7.

[0058] In summary, the glasses of this invention change the curvature of the flexible lens through a focal length adjustment component, allowing users with both myopia and presbyopia to easily change the prescription of the glasses according to the distance of the object being observed, thus enabling switching between myopia glasses and presbyopia glasses.

[0059] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above content. Therefore, the scope of protection of the present invention should be defined by the appended claims.
