Description

A flexible wire-guided hinge for eyeglasses and eyeglasses Technical Field

[0001] This utility model belongs to the field of eyeglasses technology, specifically relating to an elastic wire-passing hinge for eyeglasses and eyeglasses. Background Technology

[0002] Smart glasses, as wearable devices integrating multiple advanced technologies, are playing an increasingly important role in modern life. They not only enable real-time information display and interaction but also provide convenient support for users in various scenarios such as work, entertainment, and travel. The hinge, as a key component connecting the smart glasses frame and temples, has a crucial impact on the overall performance, appearance, and user experience of the smart glasses.

[0003] Most existing smart glasses are manufactured and sold with standardized specifications. However, head circumferences vary significantly among users, making it difficult for standardized smart glasses to meet the needs of all. For users with smaller head circumferences, the glasses may feel unstable and slip easily; while for users with larger head circumferences, the temples may excessively constrict the head, causing significant discomfort. This fit issue severely restricts the widespread adoption of smart glasses and hinders improvements in user experience.

[0004] Furthermore, in the current structural design of smart glasses, the frame typically integrates key components such as the display device, while the temples house electronic processing and control units, batteries, and other components. This necessitates a stable and reliable electrical connection between the frame and temples. Existing smart glasses hinges generally achieve this by running electrical connection wires through the hinge location. However, due to the frequent movement of the hinge during the opening and closing of the glasses, the electrical connection wires inevitably become exposed at this location. This not only makes the connection wires susceptible to interference from objects in the external environment, leading to unstable electrical connections, but also significantly reduces the lifespan of the smart glasses.

[0005] To address the aforementioned electrical connection issue, existing technologies primarily employ a retractable shell at the hinge location. This shell provides some protection for the electrical connections at the hinge when the smart glasses are opened and closed, preventing direct interference with the external environment. However, this approach undoubtedly increases the overall thickness of the hinge, undermining the original design philosophy of slimness and aesthetics in smart glasses, and consequently impacting the product's market competitiveness to some extent.

[0006] In summary, existing smart glasses hinges have many shortcomings in terms of electrical connection stability, durability, and wearability. There is an urgent need to develop a new smart glasses hinge technology to overcome these deficiencies and promote the further development of the smart glasses industry. Summary of the Invention

[0007] To address the issues of exposed electrical connection wires at the hinge position and insufficient wearability in existing smart glasses, this utility model provides a flexible wire-passing hinge for glasses and glasses.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0009] On one hand, this utility model provides an elastic through-wire hinge for eyeglasses, including an elastic element, a first connecting portion, a second connecting portion, and an electrical connecting wire. The first connecting portion and the second connecting portion are rotatably connected to form a hinge structure between the first connecting portion and the second connecting portion. The elastic element includes an arc-shaped elastic portion having a first end and a second end that can move closer to or further away from each other. The arc-shaped elastic portion surrounds the outer periphery of the hinge structure. The electrical connecting wire includes an arc-shaped line portion located between the arc-shaped elastic portion and the hinge structure. When the temple of the eyeglasses is extended to approximately 90°, the first connecting portion abuts against the first end, and the second connecting portion abuts against the second end. When the temple of the eyeglasses is further extended from approximately 90°, the distance between the first end and the second end gradually decreases, and the elastic element undergoes elastic deformation to provide elasticity that limits further extension of the temple of the eyeglasses.

[0010] Optionally, it may also include a damping element that abuts against the elastic element to provide damping when the temples of the glasses are extended or retracted.

[0011] Optionally, the damping element is a plastic part, the damping element is disposed on the second connecting part, and the damping element abuts against the outer wall of the arc-shaped elastic part.

[0012] Optionally, the first connecting part includes a buckle, a mounting part, and a hinge cylinder. The mounting part connects the buckle and the hinge cylinder respectively. The buckle is used to insert into the eyeglass post or temple. The second connecting part includes an outer shell and an inner shell. The outer shell is connected to the inner shell. A wire passage cavity is formed between the outer shell and the inner shell. The inner shell is provided with a first end cap and a second end cap that are parallel to each other and spaced apart. The first end cap and the second end cap are located on both sides of the hinge cylinder, and the first end cap, the second end cap, and the hinge cylinder are rotatably connected. The arc-shaped elastic part and the arc-shaped linear part are both located between the first end cap and the second end cap.

[0013] Optionally, the elastic element further includes a fixing seat, the first end is connected to the fixing seat, the fixing seat is detachably connected to the mounting portion, the first connecting portion further includes a protective cover, the protective cover is detachably connected to the mounting portion, and the fixing seat is located in the protective cover.

[0014] Optionally, the second end is provided with a hook that abuts against the inner housing when the temple of the glasses is extended to approximately 90°.

[0015] Optionally, a first gasket is provided between the hinge cylinder and the first end cap, and a second gasket is provided between the hinge cylinder and the second end cap.

[0016] Optionally, the electrical connection wire further includes a first segment and a second segment, the first segment and the second segment being respectively connected to the two ends of the arc-shaped part, the first segment passing through the first connection part, and the second segment passing through the second connection part.

[0017] Optionally, the elastic element is selected from metal springs or non-metal springs, and the metal spring is selected from one of zirconium-based amorphous alloy springs, copper-based amorphous alloy springs, iron-based amorphous alloy springs, magnesium-based amorphous alloy springs, or titanium-based amorphous alloy springs.

[0018] On another aspect, this utility model provides a pair of eyeglasses, including the eyeglasses elastic through-wire hinge, eyeglasses frame and eyeglasses temples as described above. The eyeglasses frame is provided with a post, one of the first connecting part and the second connecting part is connected to the post, and the other of the first connecting part and the second connecting part is connected to the eyeglasses temples.

[0019] The flexible hinge for eyeglasses provided by the present invention utilizes space fully by surrounding the hinge structure with an arc-shaped elastic part, and filling the internal space of the elastic element with the hinge structure. This reduces the volume of the flexible hinge for eyeglasses, avoiding aesthetic or wearing comfort issues caused by an excessively large flexible hinge. Furthermore, the arc-shaped part of the electrical connection wire is located between the arc-shaped elastic part and the hinge structure, effectively protecting the electrical connection wire and preventing it from being directly exposed and interfering with external objects. This improves the stability and durability of the electrical connection. Compared to existing methods that directly install a protective shell, the elastic element in this flexible hinge for eyeglasses not only serves as an elasticity-providing structure but also as a protective shell structure for the electrical connection wire, reducing the increase in hinge thickness and ensuring the slim and aesthetically pleasing design of the smart glasses. Meanwhile, when the temples of the glasses are extended to approximately 90° and then further outward, the elastic element undergoes elastic deformation to provide elasticity that limits the further outward expansion of the temples. This allows the glasses to adapt to the wearing needs of users with different head circumferences. When wearing glasses by users with larger head circumferences, the temples can be appropriately extended outward, and under the action of the elastic element, a suitable clamping force is maintained to avoid excessive clamping of the head. When wearing glasses by users with smaller head circumferences, the temples can also remain stable and are not easy to slip off, greatly improving the comfort and fit of wearing glasses.

[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] 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 or an electrical 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.

[0028] Referring to Figures 1-3, one embodiment of this utility model provides an elastic wire hinge for eyeglasses, including an elastic element 3, a first connecting portion 1, a second connecting portion 2, and an electrical connecting wire 4. The first connecting portion 1 and the second connecting portion 2 are rotatably connected to form a hinge structure between them. The elastic element 3 includes an arc-shaped elastic portion 31, which has a first end 311 and a second end 312 that can move closer to or further away from each other. The arc-shaped elastic portion 31 surrounds the outer periphery of the hinge structure. The electrical connecting wire 4 includes an arc-shaped wire portion 41, which is located between the arc-shaped elastic portion 31 and the hinge structure. When the temple of the eyeglasses is extended to approximately 90°, the first connecting portion 1 abuts against the first end 311, and the second connecting portion 2 abuts against the second end 312. When the temple of the eyeglasses is further extended from approximately 90°, the distance between the first end 311 and the second end 312 gradually decreases, and the elastic element 3 undergoes elastic deformation to provide elasticity that limits further extension of the temple of the eyeglasses.

[0029] In the aforementioned flexible hinge for eyeglasses, by surrounding the hinge structure with an arc-shaped elastic part 31, the internal space of the elastic element 3 is filled by the hinge structure, thus making full use of the space and reducing the volume of the flexible hinge for eyeglasses. This avoids aesthetic or wearing comfort issues caused by an excessively large flexible hinge for eyeglasses. Furthermore, the arc-shaped part 41 of the electrical connection line 4 is located between the arc-shaped elastic part 31 and the hinge structure, effectively protecting the electrical connection line 4 and preventing it from being directly exposed to the outside and interfering with external objects. This improves the stability and durability of the electrical connection. Compared to the existing method of directly setting a protective shell, in this flexible hinge for eyeglasses, the elastic element 3 not only serves as an elasticity-providing structure but also as a protective shell structure for the electrical connection line 4, reducing the increase in hinge thickness and ensuring the slim and aesthetically pleasing design of the smart glasses. Meanwhile, when the temples of the glasses are extended to approximately 90° and then further outward, the elastic element 3 undergoes elastic deformation to provide elasticity that limits the further outward expansion of the temples. This allows the glasses to adapt to the wearing needs of users with different head circumferences. When wearing glasses by users with larger head circumferences, the temples can be appropriately extended outward, and under the action of the elastic element 3, a suitable clamping force is maintained to avoid excessive clamping of the head. When wearing glasses by users with smaller head circumferences, the temples can also remain stable and are not easy to slip off, greatly improving the comfort and fit of wearing glasses.

[0030] In one embodiment, the eyeglasses elastic overwire hinge further includes a damping element 5 that abuts against the elastic element 3 to provide damping when the temples of the eyeglasses are extended or retracted.

[0031] By abutting between the damping member 5 and the elastic member 3, damping is formed by the frictional force generated by the damping member 5 during the relative rotation of the first connecting part 1 and the second connecting part 2, so as to enable the temple of the glasses to be suspended at any point during the unfolding and retraction process, and to maintain the stability of the temple of the glasses in the suspended position. Especially when the temple of the glasses is in the unfolded and retracted state, even if the glasses frame is picked up alone, it will not cause the temple of the glasses to wobble.

[0032] In one embodiment, the damping element 5 is a plastic part.

[0033] Compared to other materials, using plastic parts as damping components 5 provides stable damping. Specifically, plastics with wear-resistant properties can be selected, such as polyoxymethylene, nylon, polycarbonate, polyurethane, polytetrafluoroethylene, polyamide, polysulfone, polyetheretherketone, polybutylene terephthalate, polyphenylene sulfide, etc. Fillers or fibers can also be added to the plastic parts to provide reinforcement.

[0034] In one embodiment, the damping member 5 is disposed on the second connecting portion 2, and the damping member 5 abuts against the outer wall of the arc-shaped elastic portion 31.

[0035] The method of achieving damping by abutting the damping element 5 against the outer wall of the arc-shaped elastic part 31 has a longer service life, better stability, and a wider installation tolerance. Because the arc-shaped elastic part 31 itself is elastic, by abutting the damping element 5 against the outer wall of the arc-shaped elastic part 31, the elasticity of the elastic part 3 can be relied upon to keep the pressure between the elastic part 3 and the damping element 5 in a more moderate state, allowing for higher dimensional errors, reducing the requirements for machining accuracy, and avoiding the problems of excessive pressure leading to severe wear or excessive pressure leading to insufficient damping. At the same time, after the damping element 5 has undergone a certain amount of wear, it can also maintain a certain damping effect by relying on the adaptive deformation of the elastic part 3. Compared with other existing damping structures, its damping retention effect after wear is better, and it also has a higher dimensional error tolerance during installation.

[0036] In one embodiment, the first connecting part 1 includes a buckle 11, a mounting part 12, and a hinge cylinder 13. The mounting part 12 connects the buckle 11 and the hinge cylinder 13 respectively. The buckle 11 is used to insert into the eyeglass post or temple. The second connecting part 2 includes an outer shell 21 and an inner shell 22. The outer shell 21 is connected to the inner shell 22. A wire-passing cavity is formed between the outer shell 21 and the inner shell 22. The inner shell 22 is provided with parallel first ends spaced apart from each other. The first end cap 221 and the second end cap 222 are located on both sides of the hinge cylinder 13, and are rotatably connected to the hinge cylinder 13. The arc-shaped elastic part 31 is arranged around the hinge cylinder 13, and the inner diameter of the arc-shaped elastic part 31 is larger than the outer diameter of the hinge cylinder 13, so that there is a deformation space between the arc-shaped elastic part 31 and the hinge cylinder 13, which helps to ensure the elastic function of the arc-shaped elastic part 31. The arc-shaped elastic part 31 and the arc-shaped line part 41 are both located between the first end cap 221 and the second end cap 222. The first end cap 221 and the second end cap 222 provide a certain degree of protection for the side of the arc-shaped line part 41, avoiding interference between the electrical connection wire 4 and the outside.

[0037] The buckle 11 is a metal structure. During installation, the buckle 11 can be heated. After heating, the buckle 11 is inserted into the plastic eyeglass head or temple by applying pressure. After local melting due to high temperature, it is inserted and cooled to form a stable connection.

[0038] In one embodiment, the elastic element 3 further includes a fixing seat 32, the first end 311 is connected to the fixing seat 32, the fixing seat 32 is detachably connected to the mounting part 12, the first connecting part 1 further includes a protective cover 14, the protective cover 14 is detachably connected to the mounting part 12, and the fixing seat 32 is located in the protective cover 14, which can stably install and effectively protect the fixing end of the elastic element 3, prevent the fixing seat 32 from being affected by external force collision or wear during use, thus ensuring the stability and durability of the elastic function of the elastic element 3.

[0039] When the elastic element 3 is damaged during long-term use, since the elastic element 3 itself serves as the outer shell and is fixed by the fixing seat 32, when it is necessary to repair or replace the elastic element 3 of the eyeglasses elastic hinge, it is only necessary to open the protective cover 14 and remove the elastic element 3 from the fixing seat 32 and the mounting part 12. Therefore, this structure facilitates the subsequent repair and replacement of the elastic element 3.

[0040] In one embodiment, a first screw 8 is provided to pass through the fixing seat 32, the mounting part 12 and the protective cover 14 to fix the fixing seat 32, the mounting part 12 and the protective cover 14.

[0041] In one embodiment, the second end 312 is provided with a hook 313, which abuts against the inner housing 22 when the temple of the glasses is extended to approximately 90°.

[0042] The hook 313 abuts against the inner shell 22 when the temple is extended to approximately 90°, thus acting as a limit and accurately controlling the angle of the temple's extension. This ensures the temple remains stable at the commonly used extension angle and avoids unnecessary damage to the hinge structure and electrical connection line 4 due to over-extension. At this time, because the hook 313 abuts against the inner shell 22, when the temple extends further outward from approximately 90°, the hook 313 can drive the elastic element 3 to undergo elastic deformation, thus providing elasticity and allowing the temple to have a certain elastic extension margin.

[0043] In one embodiment, a first gasket 6 is provided between the hinge cylinder 13 and the first end cap 221, and a second gasket 7 is provided between the hinge cylinder 13 and the second end cap 222.

[0044] The first end cap 221, the second end cap 222, and the hinge cylinder 13 are all metal parts. If the first end cap 221, the second end cap 222, and the hinge cylinder 13 are in direct rigid contact, wear is likely to occur during long-term rotation, leading to a decrease in the friction between the first end cap 221, the second end cap 222, and the hinge cylinder 13, resulting in structural instability. The first gasket 6 and the second gasket 7, like the damping element 5, provide a certain damping effect. Furthermore, the first gasket 6 and the second gasket 7 reduce wear between the first end cap 221, the second end cap 222, and the hinge cylinder 13. Correspondingly, the first gasket 6 and the second gasket 7 are selected from self-lubricating copper gaskets or resin gaskets.

[0045] In one embodiment, a second screw 9 is provided to pass sequentially through the first end cap 221, the first washer 6, the hinge cylinder 13, the second washer 7, and the second end cap 222.

[0046] In one embodiment, the electrical connection wire 4 further includes a first segment 42 and a second segment 43, the first segment 42 and the second segment 43 being respectively connected to the two ends of the arc-shaped wire portion 41, the first segment 42 passing through the first connection portion 1, and the second segment 43 passing through the second connection portion 2.

[0047] In one embodiment, the elastic element 3 is selected from a metal spring or a non-metal spring, and the metal spring is selected from one of zirconium-based amorphous alloy spring, copper-based amorphous alloy spring, iron-based amorphous alloy spring, magnesium-based amorphous alloy spring or titanium-based amorphous alloy spring.

[0048] In a preferred embodiment, the elastic element 3 is selected from zirconium-based amorphous alloy springs.

[0049] Zirconium-based amorphous alloys boast high strength, with a tensile strength of 800-1500 MPa, 2.5 times that of 316 stainless steel and 1.5 times that of titanium alloys. This allows for thinner and lighter hinge designs, reducing component weight and improving wearer comfort. The high strength also ensures the glasses won't deform during long-term use, enhancing their overall quality. Furthermore, the Vickers hardness of zirconium-based amorphous alloys is 440-540 Hv, far exceeding that of stainless steel and titanium alloys, resulting in less wear during use. It also doesn't deform or lose elasticity over extended periods. The elastic deformation rate of zirconium-based amorphous alloys is 0.6-1.5%, six times higher than 316 stainless steel, offering better elasticity and improved wearing comfort.

[0050] Another embodiment of the present invention provides an eyeglass, including an eyeglass elastic through-wire hinge, an eyeglass frame and an eyeglass temple as described above. The eyeglass frame is provided with a post, one of the first connecting part 1 and the second connecting part 2 is connected to the post, and the other of the first connecting part 1 and the second connecting part 2 is connected to the eyeglass temple.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
