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 connections are inevitably placed between the temples and the frame for signal transmission or power supply. However, existing flexible hinges, in order to avoid contact between the elastic element and the electrical connections, place the elastic structure and the electrical connections in separate cavities, resulting in a large hinge structure and low space utilization. Therefore, overcoming these technical problems and defects is a key issue that needs to be addressed. Utility Model Content

[0006] To address the issues of large size and low space utilization of existing hinges, this invention provides an elastic threaded hinge for eyeglasses and eyeglasses.

[0039] 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.

[0042] like Figures 1-2 and Figures 7-8 As shown, in one embodiment, the present invention provides an elastic threaded hinge for eyeglasses, including a first connecting part 1, a second connecting part 2, an elastic element 3, and an electrical connecting wire 4. The first connecting part 1 includes a first hinge part 11 and a first connecting structure 14. The second connecting part 2 includes a second hinge part 21 and a second connecting structure 22. The first hinge part 11 and the second hinge part 21 are rotatably connected. The first hinge part 11 is provided with an elastic mounting part 12 and a transfer cavity 13. The elastic element 3 is located in the elastic mounting part 12, and the transfer cavity 13 is located in... Between the inner walls of the elastic mounting part 12 and the first hinge part 11, the first connecting structure 14 is provided with a first threading cavity 15, and the second connecting structure 22 is provided with a second threading cavity 23. The first threading cavity 15 and the second threading cavity 23 are interconnected via the transfer cavity 13 to form a threading channel for the electrical connection wire 4 to pass through. When the temple of the glasses is extended to approximately 90°, the elastic member 3 abuts against the first hinge part 11. When the temple of the glasses is further extended from approximately 90°, the elastic member 3 undergoes elastic deformation to provide elasticity that limits the further extension of the temple of the glasses.

[0043] Compared to other existing flexible hinge threading structures, the flexible threading hinge for eyeglasses provided by this utility model has a first connecting part 1 and a second connecting part 2 that can rotate relative to each other. The first connecting part 1 includes a first hinge part 11 and a first connecting structure 14, and a flexible mounting part 12 and a transfer cavity 13 are provided in the first hinge part 11. The flexible mounting part 12 is used for mounting and accommodating the elastic element 3. The transfer cavity 13 is located between the flexible mounting part 12 and the inner wall of the first hinge part 11, and the transfer cavity 13 is used to connect with the first threading cavity 15 and the second connecting part 2. The two threading cavities 23 together form a threading channel. The transfer cavity 13 and the elastic mounting part 12 are simultaneously arranged in the first hinge part 11, which improves the utilization rate of the internal space of the first hinge part 11, simplifies the internal space of the first hinge part 11, and reduces costs. The electrical connection line 4 is arranged between the elastic mounting part 12 and the inner wall of the first hinge part 11, thereby ensuring that the deformation of the elastic element 3 and the electrical connection line 4 in the threading channel do not interfere with each other during the unfolding and folding of the temple of the glasses, thus ensuring the stability of the electrical connection and the elastic function.

[0044] like Figure 2-3 and Figures 8-10 As shown, in one embodiment, the first hinge portion 11 includes a first component 111 and a second component 112 that are sealed and connected to each other. The first component 111 includes a first base plate 1111, a first hinge plate 1112 and a second hinge plate 1113. One side of the first hinge plate 1112 and the second hinge plate 1113 is connected to the outer periphery of the first base plate 1111. The other side of the first hinge plate 1112 and the second hinge plate 1113 extends along a direction perpendicular to the plane where the first base plate 1111 is located. The first end of the first hinge plate 1112 and the first end of the second hinge plate 1113 are respectively connected to two opposite sidewalls of the first connecting structure 14. The second end of the second hinge plate 1113 is located inside the second end of the first hinge plate 1112. The second end of the first hinge plate 1112 and the second end of the second hinge plate 1113 are misaligned to form a first channel 1114. The power supply connection line 4 passes through the first channel 1114 and is embedded in the second wiring cavity 23.

[0045] Specifically, the second end of the second hinge plate 1113 is thinned and has a gap with the outer periphery of the first base plate 1111. When the first hinge part 11 and the second hinge part 21 rotate relative to each other, the second end of the second hinge plate 1113 does not contact the inner wall of the second hinge part 21, thereby reducing the frictional force when the first hinge part 11 and the second hinge part 21 rotate.

[0046] The second end of the second hinge plate 1113 is located inside the second end of the first hinge plate 1112. The second end of the first hinge plate 1112 and the second end of the second hinge plate 1113 are misaligned to form a first channel 1114, which facilitates the electrical connection wire 4 to be embedded into the second wire passage cavity 23 through the first channel 1114.

[0047] The first hinge portion 11 is configured as an independent first component 111 and a second component 112, which facilitates the fixing of the elastic element 3 to the elastic mounting portion 12 and the fixing of the electrical connection wire 4 in the transfer cavity 13. At the same time, the first connecting structure 14 and the second connecting structure 22 can be connected to each other by screws or other means for fixed installation. When repairing the elastic threaded hinge for eyeglasses, the first component 111 or the second component 112 can be separated to expose the elastic mounting portion 12 and the transfer cavity 13, so that the components inside the elastic mounting portion 12 and the transfer cavity 13 can be repaired separately. This avoids the impact of repair operations on other non-repairable functional components and disassembly operations, which helps to reduce the difficulty of repair.

[0048] like Figure 5 As shown, in one embodiment, the second component 112 includes a second base plate 1121, a second hinge plate 1113 is provided with a first slot 1115 at one end opposite to the first base plate 1111, and a first block 1125 is provided on the second base plate 1121 at the position corresponding to the first slot 1115. The first component 111 and the second component 112 are connected to the first slot 1115 through the first block 1125.

[0049] Specifically, the first component 111 and the second component 112 are connected to the first slot 1115 via the first locking block 1125, which facilitates quick assembly of the first component 111 and the second component 112. At the same time, when repairing the eyeglasses with the elastic threaded hinge, the first component 111 or the second component 112 can be disassembled by separating the first locking block 1125 from the first slot 1115 to expose the elastic mounting part 12 and the transfer cavity 13. Then, the components inside the elastic mounting part 12 and the transfer cavity 13 can be repaired separately, thereby avoiding the impact on other non-repairable functional components and disassembly operations during the repair operation, which helps to reduce the difficulty of repair.

[0050] like Figure 10 As shown, in one embodiment, the second component 112 includes a second base plate 1121, a third hinge plate 1122, and a fourth hinge plate 1123. One side of the third hinge plate 1122 and the fourth hinge plate 1123 is connected to the outer periphery of the second base plate 1121, and the other side of the third hinge plate 1122 and the fourth hinge plate 1123 extends along a direction perpendicular to the plane of the second base plate 1121. The first end of the third hinge plate 1122 and the first end of the fourth hinge plate 1123 are respectively connected to two opposite sidewalls of the first connecting structure 14. The second end of the fourth hinge plate 1123 is located inside the second end of the third hinge plate 1122. The second end of the third hinge plate 1122 and the second end of the fourth hinge plate 1123 are misaligned to form a second channel 1124. The first channel 1114 and the second channel 1124 form a sealed channel through which the power supply connection line 4 passes and is embedded in the second wiring cavity 23.

[0051] The second hinge plate 1113 has a first slot 1115 at one end away from the first base plate 1111, and the fourth hinge plate 1123 has a first block 1125 at one end away from the second base plate 1121. The first component 111 and the second component 112 are connected to the first slot 1115 through the first block 1125.

[0052] Specifically, the second end of the fourth hinge plate 1123 is thinned and has a gap with the outer periphery of the second base plate 1121. When the first hinge part 11 and the second hinge part 21 rotate relative to each other, the second end of the fourth hinge plate 1123 does not contact the inner wall of the second hinge part 21, thereby reducing the frictional force when the first hinge part 11 and the second hinge part 21 rotate.

[0053] The second end of the fourth hinge plate 1123 is located inside the second end of the third hinge plate 1122. The second end of the fourth hinge plate 1123 and the second end of the third hinge plate 1122 are misaligned to form a second channel 1124. The first channel 1114 and the second channel 1124 form a closed channel, which facilitates the electrical connection wire 4 to be embedded into the second wire passage cavity 23 through the first channel 1114 and the second channel 1124.

[0054] Specifically, the first component 111 and the second component 112 are connected to the first slot 1115 via the first locking block 1125, which facilitates quick assembly of the first component 111 and the second component 112. At the same time, when repairing the eyeglasses with the elastic threaded hinge, the first component 111 or the second component 112 can be disassembled by separating the first locking block 1125 from the first slot 1115 to expose the elastic mounting part 12 and the transfer cavity 13. Then, the components inside the elastic mounting part 12 and the transfer cavity 13 can be repaired separately, thereby avoiding the impact on other non-repairable functional components and disassembly operations during the repair operation, which helps to reduce the difficulty of repair.

[0055] like Figure 2 and Figure 8 As shown, in one embodiment, the electrical connection wire 4 includes an arc-shaped portion 41 and straight portions 42 disposed at both ends of the arc-shaped portion 41. The arc-shaped portion 41 is located inside the first hinge cylinder and abuts against the inner wall of the first hinge plate 1112, and / or...

[0056] The arc-shaped part 41 is located inside the first hinge cylinder and the second hinge cylinder, and abuts against the inner walls of the first hinge plate 1112 and the third hinge plate 1122.

[0057] The straight portion 42 passes through the first threading cavity 15 and the second threading cavity 23 respectively and connects to the first connecting structure 14 and the second connecting structure 22.

[0058] Specifically, the arc-shaped part 41 is located between the inner wall of the first hinge plate 1112 and the elastic mounting part 12, or the arc-shaped part 41 is located between the inner wall of the first hinge plate 1112, the inner wall of the third hinge plate 1122 and the elastic mounting part 12; thereby avoiding mutual interference between the deformation of the elastic element 3 and the electrical connection wire 4 in the wiring channel during the unfolding and folding of the eyeglass temple, ensuring the stability of the electrical connection and the elastic function.

[0059] The straight section 42 is designed to facilitate embedding into the corresponding first threading cavity 15 and second threading cavity 23.

[0060] like Figure 2 and Figure 8 As shown, in one embodiment, the elastic mounting portion 12 includes a first elastic mounting portion 121 and a second elastic mounting portion 122. A first base plate 1111 protrudes towards the second base plate 1121 to form the first elastic mounting portion 121, and a second base plate 1121 protrudes towards the first base plate 1111 to form the second elastic mounting portion 122. An elastic member 3 is located between the first elastic mounting portion 121 and the second elastic mounting portion 122. The first elastic mounting portion 121 is provided with a first moving hole 1211 and a first fixing hole 1212. The second elastic mounting portion 122 is provided with a second moving hole 1221 corresponding to the position of the first moving hole 1211, and a second fixing hole 1222 corresponding to the position of the first fixing hole 1212. The elastic member 3 is a ring-like structure with an opening, and the elastic member 3 surrounds the first elastic mounting portion 121 and the second elastic mounting portion 122. The rotation axis of the second elastic mounting part 122 is set, and the elastic member 3 has a first end 31 and a second end 32 that can move closer to or further away from each other at the opening position; the two ends of the first end 31 are respectively fixed in the first fixing hole 1212 and the second fixing hole 1222, and the two ends of the second end 32 are respectively embedded in the first moving hole 1211 and the second moving hole 1221 and move within the first moving hole 1211 and the second moving hole 1221; in the initial state, the two ends of the second end 32 abut against one end of the first moving hole 1211 and the second moving hole 1221, respectively; when the temple of the glasses is extended to approximately 90°, the two ends of the second end 32 abut against the other end of the first moving hole 1211 and the second moving hole 1221, respectively; when the temple of the glasses is further extended from approximately 90°, the elastic member 3 undergoes elastic deformation to provide elasticity that limits the further extension of the temple of the glasses.

[0061] The first base plate 1111 protrudes towards the second base plate 1121 to form a first elastic mounting portion 121, and the second base plate 1121 protrudes towards the first base plate 1111 to form a second elastic mounting portion 122. In one embodiment, a transfer cavity 13 is formed between the outer wall of the first elastic mounting portion 121, the outer wall of the second elastic mounting portion 122, and the inner wall of the first hinge plate 1112; or the first transfer cavity is formed between the outer wall of the first elastic mounting portion 121 and the inner wall of the first hinge plate 1112, and the second transfer cavity is formed between the outer wall of the second elastic mounting portion 122 and the inner wall of the second hinge plate 1113. The first transfer cavity and the second transfer cavity together form the transfer cavity 13. The arc-shaped portion 41 of the electrical connection wire 4 is embedded in the transfer cavity 13, effectively separating the elastic element 3 and the electrical connection wire 4 from each other, thereby ensuring that the deformation of the elastic element 3 and the electrical connection wire 4 in the wire channel do not interfere with each other during the unfolding and folding of the temple of the glasses, ensuring the stability of the electrical connection and the elastic function.

[0062] Compared to other existing elastic hinge structures, the elastic threaded hinge for eyeglasses uses an elastic element 3 with an opening-like ring structure, which can achieve a longer elastic stroke in a smaller space, reducing the volume of the elastic threaded hinge for eyeglasses and avoiding problems with aesthetics or wearing comfort caused by an excessively large elastic threaded hinge for eyeglasses.

[0063] The two ends of the first end 31 of the elastic element 3 are respectively fixed in the first fixing hole 1212 and the second fixing hole 1222, and the two ends of the second end 32 are respectively embedded in the first moving hole 1211 and the second moving hole 1221, and the second end 32 can move within the first moving hole 1211 and the second moving hole 1221; in the initial state, the two ends of the second end 32 abut against one end of the first moving hole 1211 and the second moving hole 1221, respectively. During the unfolding of the temples, the second end 32 of the elastic element 3 moves within the first moving hole 1211 and the second moving hole 1221. When the temple is extended to approximately 90°, the two ends of the second end 32 abut against the other ends of the first moving hole 1211 and the second moving hole 1221, respectively. When the temple expands further outward from approximately 90°, the elastic element 3 undergoes elastic deformation to provide elasticity that limits the further outward expansion of the temple. This allows for direct force transmission between the elastic element 3 and the first hinge portion 11 or between the elastic element 3 and the second connecting portion 2, preventing the elastic element 3 from breaking as a direct point of tension. The hinge structure reduces the external force on the elastic element 3 and improves its resistance to external force breakage.

[0064] In some embodiments, the elastic element 3 is selected from metal springs or non-metal springs, and the metal springs are selected from 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.

[0065] In a preferred embodiment, the elastic element 3 is selected from zirconium-based amorphous alloys.

[0066] 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.

[0067] like Figures 8-10 As shown, in one embodiment, the first connecting structure 14 includes a first connecting component 141 and a second connecting component 142. The first connecting component 141 is connected to the first hinge cylinder, and the second connecting component 142 is connected to the second hinge cylinder. A first groove 151 is provided on the side of the first connecting component 141 near the second connecting component 142, and a second groove 152 is provided on the side of the second connecting component 142 near the first connecting component 141. The first groove 151 and the second groove 152 form a first threading cavity 15.

[0068] A first groove 151 is directly formed on the first connecting component 141, and a second groove 152 is directly formed on the second connecting component 142. The first groove 151 and the second groove 152 form a first threading cavity 15, which facilitates rapid processing and forming.

[0069] like Figure 2 and Figure 8 As shown, in one embodiment, the second hinge portion 21 includes a third component 211 and a fourth component 212. The third component 211 includes a third base plate 2111 and a first hinge cylinder 2112. One end of the first hinge cylinder 2112 is connected to the outer periphery of the third base plate 2111. The outer wall of the first hinge cylinder 2112 is connected to the second connecting structure 22. The first hinge cylinder 2112 is provided with a first groove 2113 at the position corresponding to the second hinge plate 1113. The second hinge plate 1113 can rotate within the first groove 2113. The third base plate 2111 is provided with a first limiting block 2114 at the position corresponding to the first moving hole 1211. The first limiting block 2114 is embedded in the first moving hole 1211.

[0070] Specifically, the first groove 2113 facilitates the placement of the first hinge 11 inside the second hinge 21. Simultaneously, one end of the first connecting structure 14, connected to the first hinge 11, is also located within the first groove 2113. In the initial state, one side of the first connecting structure 14 abuts against one end of the first groove 2113. During the unfolding of the temples, the first connecting structure 14 drives the first hinge 11 to rotate within the second hinge 21. When the temples are unfolded to approximately 90°, the other side of the first connecting structure 14 abuts against the other end of the first groove 2113. The first groove 2113 restricts the elasticity of further outward expansion of the temples, thus preventing the elastic element 3 from breaking as a direct point of tension. This hinge structure reduces the external force on the elastic element 3, improving its resistance to breakage.

[0071] like Figure 2 and Figure 6 As shown, in one embodiment, the fourth component 212 includes a fourth base plate 2121, a second slot 2115 is provided at one end of the first hinge cylinder 2112 away from the third base plate 2111, and a second block 2125 is provided on the fourth base plate 2121 at the position corresponding to the second slot 2115. The third component 211 and the fourth component 212 are connected to the second slot 2115 through the second block 2125.

[0072] Specifically, the first hinge cylinder 2112 has multiple second slots 2115 at one end away from the third base plate 2111. The first hinge cylinder 2112 has two second slots 2115 parallel to the plane of the third base plate 2111, and the two second slots 2115 are symmetrically arranged on the first hinge cylinder 2112. The first hinge cylinder 2112 has one second slot 2115 perpendicular to the plane of the third base plate 2111. The fourth base plate 2121 has second blocks 2125 at positions corresponding to the second slots 2115. The third component 211 and the fourth component 212 are connected to the multiple second slots 2115 through the multiple second blocks 2125. This facilitates the quick assembly of the third component 211 and the fourth component 212. At the same time, when repairing the glasses using the elastic threaded hinge, the third component 211 and the fourth component 212 can be separated by separating the second blocks 2125 from the second slots 2115, thereby separating the first connecting part 1 from the second connecting part 2.

[0073] like Figure 8 and Figure 11As shown, in one embodiment, the fourth component 212 includes a fourth base plate 2121 and a second hinge cylinder 2122. The second hinge cylinder 2122 is connected to the outer periphery of the fourth base plate 2121. The sidewall of the second hinge cylinder 2122 is connected to the second connecting structure 22. The second hinge cylinder 2122 is provided with a second groove 2123 at the position corresponding to the fourth hinge plate 1123. The second groove 2123 is connected to the first groove 2113. The second hinge plate 1113 and the fourth hinge plate 1123 can rotate within the first groove 2113 and the second groove 2123. The fourth base plate 2121 is provided with a second limiting block 2124 at the position corresponding to the second moving hole 1221. The second limiting block 2124 is embedded in the second moving hole 1221.

[0074] Specifically, the second groove 2123 and the first groove 2113 are separately arranged, which facilitates the placement of the first hinge part 11 inside the second hinge part 21. At the same time, one end of the first connecting structure 14 connected to the first hinge part 11 is also located inside the first groove 2113 and the second groove 2123. In the initial state, one side of the first connecting structure 14 abuts against one end of the first groove 2113 and the second groove 2123. During the unfolding of the temple, the first connecting structure 14 drives the first hinge part 11 to rotate within the second hinge part 21. When the temple is unfolded to approximately 90°, the other side of the first connecting structure 14 abuts against the other end of the first groove 2113 and the second groove 2123. The arrangement of the first groove 2113 and the second groove 2123 can limit the elasticity of the temple to further expand outward, thereby preventing the elastic element 3 from breaking as a direct tensile stress point. The hinge structure can reduce the external force on the elastic element 3 and improve the resistance of the elastic element 3 to external force breakage.

[0075] like Figure 8 and Figure 11 As shown, in one embodiment, the second connecting structure 22 includes a third connecting component 221 and a fourth connecting component 222. The third connecting component 221 communicates with the first hinge cylinder 2112, and the fourth connecting component 222 communicates with the second hinge cylinder 2122. A third groove 231 is provided on the side of the third connecting component 221 near the fourth connecting component 222, and a fourth groove 232 is provided on the side of the fourth connecting component 222 near the third connecting component 221. The third groove 231 and the fourth groove 232 form a second threading cavity 23.

[0076] A third groove 231 is directly formed on the third connecting component 221, and a fourth groove 232 is directly formed on the fourth connecting component 222. The third groove 231 and the fourth groove 232 form a second threading cavity 23, which facilitates the rapid processing and forming of the second threading cavity 23.

[0077] like Figure 2 and Figure 8As shown, in one embodiment, a first sealing ring 51 and a second sealing ring 52 are also included. The first sealing ring 51 is disposed between the third component 211 and the first component 111, and the second sealing ring 52 is disposed between the fourth component 212 and the second component 112 to seal the elastic mounting portion 12.

[0078] The first sealing ring 51 and the second sealing ring 52 are used to seal the elastic mounting part 12, which can prevent external dust from entering the elastic mounting part 12 and ensure that the elastic element 3 is not interfered with by external structures.

[0079] In one embodiment, the present invention provides another aspect of eyeglasses, including an elastic threaded hinge for eyeglasses as described above, an eyeglass frame and an eyeglass temple, wherein a post is provided on the eyeglass frame, one of a first connecting part 1 and a 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.

[0080] In one embodiment, a left post and a right post are respectively provided on both sides of the eyeglass frame, and the eyeglasses include two eyeglass hinges with elastic thread, which are respectively provided at the left post and the right post of the eyeglasses.

[0081] Furthermore, one of the first connecting part 1 and the second connecting part 2 is connected to one end of the pile head, and the connection method can be selected from one of the following: heat fusion connection, riveting or screw connection.

[0082] In one embodiment, the other of the first connecting part 1 and the second connecting part 2 is used to connect to one end of the temple of the eyeglasses, and the connection method between the temple of the eyeglasses and the first connecting part 1 or the second connecting part 2 is selected from one of heat fusion connection, riveting or screw connection.
