Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an elastic threaded hinge for eyeglasses and eyeglasses. Background Technology

[0002] Eyeglass hinges connect the temples to the frame. Typically, the temples in eyeglass frames are strip-shaped, connected to the frame via a hinge structure. When in use, the temples are fully extended, resting on the ears and clamping against the sides of the face, securing the eyeglasses. The opening range of the temples is often not perfectly suited to the wearer's head width. If the opening is too small, it will clamp the head, causing discomfort; if the opening is too large, it will result in insufficient stability and the frame may shift.

[0003] There is a type of flexible hinge for eyeglasses that improves fit and wearing comfort by incorporating an elastic structure to create a certain degree of elasticity between the temples and the frame. However, the elasticity of this type of hinge is mainly reflected in the elastic force generated when the temples are extended to a 90° angle. During the extension and retraction of the temples, the resistance is relatively small, resulting in insufficient stability during temple swing and suspension.

[0004] In particular, with the development of intelligent wearable devices, when this type of eyeglass hinge is applied to smart glasses, the weight of the eyeglass temples is usually relatively large because they are usually equipped with electronic devices such as speakers or other sensors. The insufficient stability of the eyeglass hinge in swinging and hovering is more obvious, and it is easy to shake and produce a large swing amplitude when not in use.

[0005] On the other hand, in smart glasses, electrical connection lines are inevitably set between the temples and the frame for signal transmission or power supply. However, existing flexible hinges for glasses place the flexible structure and the electrical connection lines in the same cavity. During the long-term unfolding and folding of the temples, the deformation of the flexible structure will interfere with the electrical connection lines, leading to wear of the electrical connection lines and affecting their electrical connection stability. Utility Model Content

[0006] To address the problem of interference between existing flexible hinges for eyeglasses and electrical connection wires when applied to smart glasses, this invention provides a flexible wire-passing hinge for eyeglasses and the eyeglasses themselves.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0008] On one hand, this utility model provides an elastic wire-passing hinge for eyeglasses, including a first connecting part, a second connecting part, and an elastic element. The first connecting part has a first wire-passing cavity inside, and the second connecting part has a second wire-passing cavity, an elastic mounting cavity, and a transfer cavity. The first connecting part is provided with a hinge plate, and the second connecting part is rotatably connected to the hinge plate. The elastic mounting cavity and the transfer cavity are separated from each other by the hinge plate. The first wire-passing cavity and the second wire-passing cavity are interconnected through the transfer cavity to form a wire-passing channel for electrical connection wires to pass through. The elastic element is located in the elastic mounting cavity. When the temple of the eyeglasses is extended to approximately 90°, the elastic element abuts against the hinge plate and the second connecting part respectively. When the temple of the eyeglasses is further extended from approximately 90°, the elastic element undergoes elastic deformation to provide elasticity that limits further extension of the temple of the eyeglasses.

[0009] Optionally, the second connecting part includes a first component and a second component. The first component includes a first connecting structure and a first fastener that are connected to each other. The second component includes a second connecting structure and a second fastener that are connected to each other. The first connecting structure is connected to the second connecting structure. The first fastener and the second fastener are respectively sleeved on both sides of the hinge plate. The elastic mounting cavity is located in the first fastener and is closed by the hinge plate. The transfer cavity is located in the second fastener and is closed by the hinge plate.

[0010] Optionally, the second cable passage cavity is located in the second connecting structure, and the second connecting structure has a first channel connecting the transfer cavity and the first cable passage cavity, and the hinge plate has a second channel connecting the transfer cavity and the first cable passage cavity.

[0011] Optionally, a damping element is also included. The elastic element is a ring-like structure with an opening. The elastic element is arranged around the rotation axis of the second connecting portion and the hinge plate. The elastic element has a first end and a second end that can move closer to or further away from each other at the opening position. The damping element abuts against the elastic element to provide damping when the temples of the glasses are extended or retracted. When the temples of the glasses are extended to approximately 90°, the hinge plate directly or indirectly abuts against the first end, and the first fastener directly or indirectly abuts against the second end. When the temples of the glasses are 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 temples of the glasses.

[0012] Optionally, the damping element includes a clamping portion and a first sealing ring. The clamping portion is connected to the first sealing ring, and the first sealing ring is located between the first fastener and the hinge plate to seal the elastic mounting cavity. The outer wall of the clamping portion abuts against the inner wall of the first fastener, and the inner wall of the clamping portion abuts against the outer wall of the elastic element to form a clamping prestress.

[0013] Optionally, the number of clamping parts is multiple, and the multiple clamping parts are arranged around the first sealing ring at intervals. The inner walls of the multiple clamping parts are located on the same preset circle, and in the non-installation state, the radius of the preset circle is smaller than the outer diameter of the elastic element, so that in the installation state, the multiple clamping parts form a clamping prestress on the elastic element.

[0014] Optionally, a first hinge cylinder and a second hinge cylinder are respectively provided on both sides of the hinge plate, the first fastener is rotatably sleeved on the first hinge cylinder, and the second fastener is rotatably sleeved on the second hinge cylinder.

[0015] Optionally, a second sealing ring is provided between the second fastener and the hinge plate to seal the transfer cavity.

[0016] 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, and titanium-based amorphous alloy springs.

[0017] On another aspect, this utility model provides an eyeglass, including the elastic wire hinge for eyeglasses, an eyeglass frame, and an eyeglass temple as described above. The eyeglass 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 eyeglass temple.

[0018] Compared to other existing flexible hinge wire-passing structures, the flexible wire-passing hinge for eyeglasses provided by this utility model has a first connecting part and a second connecting part that can rotate relative to each other. The second connecting part contains an elastic mounting cavity and a transfer cavity. When the first connecting part and the second connecting part are rotatably connected, the hinge plate separates the elastic mounting cavity and the transfer cavity. The elastic mounting cavity is used to accommodate the elastic element, and the transfer cavity, together with the first and second wire-passing cavities, forms a wire-passing channel, effectively separating the elastic element and the wire-passing channel. This ensures that during the unfolding and folding of the eyeglass temples, the deformation of the elastic element does not interfere with the electrical connection wires in the wire-passing channel, guaranteeing electrical connection stability and elastic function.

[0027] 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.

[0028] See Figures 1-6As shown, this utility model embodiment provides an elastic wire-passing hinge for eyeglasses, including a first connecting part 1, a second connecting part 2, and an elastic member 5. The first connecting part 1 has a first wire-passing cavity 15 inside, and the second connecting part 2 has a second wire-passing cavity 223, an elastic mounting cavity 213, and a transfer cavity 224. The first connecting part 1 has a hinge plate 11, and the second connecting part 2 is rotatably connected to the hinge plate 11. The elastic mounting cavity 213 and the transfer cavity 224 are separated from each other by the hinge plate 11. The first wire-passing cavity 15 and the second wire-passing cavity 223 are interconnected through the transfer cavity 224 to form a wire-passing channel for electrical connection wires to pass through. The elastic member 5 is located in the elastic mounting cavity 213. When the temple of the eyeglasses is extended to approximately 90°, the elastic member 5 abuts against the hinge plate 11 and the second connecting part 2 respectively. When the temple of the eyeglasses is further extended from approximately 90°, the elastic member 5 undergoes elastic deformation to provide elasticity that limits further extension of the temple of the eyeglasses.

[0029] Compared to other existing flexible hinge wire-passing structures, the flexible wire-passing hinge for eyeglasses provided by this utility model is provided with a first connecting part 1 and a second connecting part 2 that can rotate relative to each other. The second connecting part 2 is provided with an elastic mounting cavity 213 and a transfer cavity 224. When the first connecting part 1 and the second connecting part 2 are rotatably connected, the hinge plate 11 separates the elastic mounting cavity 213 and the transfer cavity 224 from each other. The elastic mounting cavity 213 is used to accommodate the elastic element 5, and the transfer cavity 224 is used to form a wire-passing channel together with the first wire-passing cavity 15 and the second wire-passing cavity 223, thereby effectively separating the elastic element 5 and the wire-passing channel from each other. This ensures that during the unfolding and folding of the eyeglass temple, the deformation of the elastic element 5 does not interfere with the electrical connection wires in the wire-passing channel, thus ensuring the stability of the electrical connection and the elastic function.

[0030] In one embodiment, the second connecting part 2 includes a first component 21 and a second component 22. The first component 21 includes a first connecting structure 211 and a first fastener 212 connected to each other. The second component 22 includes a second connecting structure 221 and a second fastener 222 connected to each other. The first connecting structure 211 is connected to the second connecting structure 221. The first fastener 212 and the second fastener 222 are respectively sleeved on both sides of the hinge plate 11. The elastic mounting cavity 213 is located in the first fastener 212 and is closed by the hinge plate 11. The transfer cavity 224 is located in the second fastener 222 and is closed by the hinge plate 11.

[0031] The second connecting part 2 is configured as an independent first component 21 and a second component 22. The first connecting structure 211 and the second connecting structure 221 can be connected to each other for fixed installation by screws or other means. At the same time, the elastic mounting cavity 213 is located in the first fastener 212 and closed by the hinge plate 11, and the transfer cavity 224 is located in the second fastener 222 and closed by the hinge plate 11. This facilitates the separation of the mounting structures of the elastic mounting cavity 213 and the transfer cavity 224. When repairing the eyeglasses elastic through-wire hinge, the first component 21 or the second component 22 can be separated to expose the elastic mounting cavity 213 and the transfer cavity 224. Then, the components inside the elastic mounting cavity 213 and the transfer cavity 224 can be repaired separately, thereby avoiding the impact of repair operations on other non-repairable functional components and disassembly operations, which helps to reduce the difficulty of repair.

[0032] like Figure 4 As shown, in one embodiment, the second cable passage cavity 223 is located in the second connecting structure 221, and the second connecting structure 221 has a first channel 225 connecting the transfer cavity 224 and the first cable passage cavity 15, as shown. Figure 5 As shown, the hinge plate 11 has a second channel 14 that connects the transfer cavity 224 and the first wire passage cavity 15.

[0033] By setting the second channel 14 on the hinge plate 11, specifically, the hinge plate 11 is a near-circular structure, and the second channel 14 is led out from the center of the hinge plate 11, it is beneficial to reduce the interference problem between the electrical connection line and the second connection structure 221 during the rotation of the elastic through-wire hinge for eyeglasses.

[0034] In one embodiment, the flexible through-wire hinge for eyeglasses further includes a damping element 3. The flexible element 5 is a ring-like structure with an opening. The flexible element 5 is arranged around the rotation axis of the second connecting portion 2 and the hinge plate 11. The flexible element 5 has a first end 51 and a second end 52 that can move closer to or further away from each other at the opening position. The damping element 3 abuts against the flexible element 5 to provide damping when the temple of the eyeglasses is extended or retracted. When the temple of the eyeglasses is extended to approximately 90°, the hinge plate 11 directly or indirectly abuts against the first end 51, and the first fastener 212 directly or indirectly abuts against the second end 52. When the temple of the eyeglasses is further extended from approximately 90°, the distance between the first end 51 and the second end 52 gradually decreases, and the flexible element 5 undergoes elastic deformation to provide elasticity that limits further extension of the temple of the eyeglasses.

[0035] Compared to other existing elastic hinge structures, the elastic hinge for eyeglasses uses an elastic element 5 with an opening-like ring structure, which can achieve a longer elastic stroke in a smaller space, reducing the volume of the elastic hinge for eyeglasses and avoiding aesthetic or wearing comfort issues caused by an excessively large elastic hinge for eyeglasses.

[0036] To ensure the stability of the temples during the unfolding and retraction process, a damping element 3 is provided. The damping element 3 abuts against the elastic element 5, thereby generating damping through the frictional force generated by the damping element 3 during the relative rotation of the first connecting part 1 and the second connecting part 2. This allows the temples to be suspended at any point during the unfolding and retraction process and maintain the stability of the temples at that suspended position. Especially when the temples are in the unfolded and retracted state, even if the eyeglass frame is picked up separately, the temples will not wobble.

[0037] In some embodiments, the damping element 3 is a metal part, a plastic part, or a composite material. Specifically, when the damping element 3 is a metal part, a metal with self-lubricating properties, such as brass, can be selected to avoid noise or excessive damping during friction. When the damping element 3 is a composite material, plastic material can be formed on the surface of the metal support, and the plastic part can contact the elastic element to provide a damping effect.

[0038] In a preferred embodiment, the damping element 3 is a plastic part.

[0039] Compared to other materials, using plastic parts as damping components 3 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.

[0040] In one embodiment, the damping member 3 includes a clamping portion 32 and a first sealing ring 31. The clamping portion 32 is connected to the first sealing ring 31, and the first sealing ring 31 is located between the first fastener 212 and the hinge plate 11 to seal the elastic mounting cavity 213. The outer wall of the clamping portion 32 abuts against the inner wall of the first fastener 212, and the inner wall of the clamping portion 32 abuts against the outer wall of the elastic member 5 to form a clamping prestress.

[0041] During the rotation of the temple of the glasses, the position of the damping member 3 is fixed to the position of the hinge plate 11.

[0042] The first sealing ring 31 is used to seal the elastic safety cavity, which can prevent external dust from entering the elastic safety cavity and ensure that the elastic element 5 is not interfered with by external structures.

[0043] The method of achieving damping by abutting the clamping part 32 against the outer wall of the elastic member 5 has a longer service life, better stability, and a wider installation tolerance. Because the elastic member 5 itself is elastic, by abutting the clamping part 32 with the elastic member 5, the clamping prestress between the elastic member 5 and the clamping part 32 can be kept in a more moderate state by relying on the elasticity of the elastic member 5. This avoids the problem of excessive pressure leading to severe wear or excessive pressure leading to insufficient damping. At the same time, after the clamping part 32 has undergone a certain amount of wear, it can also maintain a certain damping effect by relying on the adaptive deformation of the elastic member 5. Compared with the method of directly contacting the damping member 3 with the rigid structure, its damping retention effect after wear is better, and it also has a higher dimensional error tolerance during installation.

[0044] In one embodiment, there are multiple clamping portions 32, which are arranged around the first sealing ring 31 at intervals. The inner walls of the multiple clamping portions 32 are located on the same preset circle, and in the non-installed state, the radius of the preset circle is smaller than the outer diameter of the elastic member 5, so that in the installed state, the multiple clamping portions 32 form a clamping prestress on the elastic member 5.

[0045] By setting multiple clamping parts 32, the clamping prestress of the elastic element 5 in different directions can be kept in balance, thus avoiding the problem of eccentric displacement of the elastic element 5.

[0046] Specifically, in this embodiment, the number of clamping parts 32 is two.

[0047] like Figure 3 As shown, in one embodiment, the first fastener 212 is provided with a slot 214, and the first end 51 of the elastic member 5 is embedded in the slot 214. The slot 214 fixes the first end 51 of the elastic member 5, and the second end 52 of the elastic member 5 is a free end, such as... Figure 6As shown, the side wall of the hinge plate 11 is provided with a locking block 16. When the temple of the glasses is extended to approximately 90°, the second end 52 of the elastic member 5 abuts against the locking block 16 and is limited. During the process of the temple of the glasses being extended to approximately 90°, the damping member 3 and the hinge plate 11 are relatively fixed in position. At this time, since the first end 51 of the elastic member 5 is fixed relative to the first fastener 212, the first fastener 212 drives the elastic member 5 to rotate relative to the clamping part 32. Therefore, the clamping part 32 slides around the outer wall of the elastic member 5 and provides damping. When the temple of the glasses is further extended from approximately 90°, the locking block 16 drives the second end 52 of the elastic member 5 and the first fastener 212 drives the first end 51 of the elastic member 5, so that the first end 51 and the second end 52 of the elastic member 5 are relatively close to each other, generating elastic force, which plays the role of providing elasticity for the temple of the glasses to expand outward.

[0048] In one embodiment, a first hinge cylinder 12 and a second hinge cylinder 13 are respectively provided on both sides of the hinge plate 11. The first fastener 212 is rotatably sleeved on the first hinge cylinder 12, and the second fastener 222 is rotatably sleeved on the second hinge cylinder 13.

[0049] The first hinge cylinder 12 and the second hinge cylinder 13 are used to support the first fastener 212 and the second fastener 222. This structure can achieve the rotation function without setting a pivot in the center position, thus avoiding the influence of the pivot setting on the line passing function. Without affecting the function of the elastic element 5, a protruding wall 17 can be set on the first hinge cylinder 12 and / or the second hinge cylinder 13 to improve its support strength. Furthermore, the protruding wall 17 plays the role of restricting the rotation of the damping element 3 relative to the hinge plate 11.

[0050] In one embodiment, a second sealing ring 4 is provided between the second fastener 222 and the hinge plate 11 to seal the transfer cavity 224.

[0051] The second sealing ring 4 is used to seal the transfer cavity 224, which can prevent external dust from entering the transfer cavity 224 and ensure that the electrical connection wires therein are not interfered with by external structures.

[0052] On the other hand, since both the first connecting part 1 and the second connecting part 2 are metal parts, if the first connecting part 1 and the second connecting part 2 are in direct rigid contact, wear is likely to occur during long-term rotation, resulting in a decrease in the friction between the first connecting part 1 and the second connecting part 2, which leads to structural instability. The first sealing ring 31 and the second sealing ring 4 are provided to prevent wear between the first connecting part 1 and the second connecting part 2. Since the first sealing ring 31 and the second sealing ring 4 are plastic parts, their surfaces in contact with metal have deformation adaptability, which can reduce surface wear during long-term use. At the same time, even after wear occurs, replacing the damping part 3 and the second sealing ring 4 separately has a better cost advantage, because the first connecting part 1 and the second connecting part 2 are usually integrally formed with the eyeglass frame and the temple, respectively, resulting in a large replacement cost.

[0053] In some embodiments, the elastic element 5 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, and titanium-based amorphous alloy springs.

[0054] In a preferred embodiment, the elastic element 5 is selected from zirconium-based amorphous alloys.

[0055] 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.

[0056] Another embodiment of the present invention provides an eyeglass, including an elastic wire hinge for eyeglasses as described above, an eyeglass frame and an eyeglass temple, wherein a post is provided on the eyeglass frame, 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.

[0057] 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.
