Description

Technical Field

[0001] This application relates to the field of eyewear technology, and more particularly to an eyewear hinge and eyewear. Background Technology

[0002] Eyeglasses, as a widely used optical instrument and wearable device, are basically constructed by connecting the frame and temples via hinges. For a long time, most eyeglasses on the market, including the currently developing smart glasses, have used rigid or friction-based hinges between the temples and the frame. These traditional hinges can only fix the temples in two positions: open and folded. They lack adaptive adjustment capabilities, and the clamping force is fixed at the factory, making it difficult to adapt to differences in head shape and circumference. This results in a clamping force that is too loose for users with smaller heads, causing the glasses to slip easily, while a clamping force that is too tight for users with larger heads, creating a feeling of pressure and severely affecting wearing comfort.

[0003] Therefore, existing eyeglasses based on rigid hinges inherently lack wearing comfort. The industry urgently needs a new type of hinge or eyeglasses that can dynamically provide moderate clamping force. Summary of the Invention

[0004] This application provides an eyeglass hinge and eyeglasses, aiming to improve the problem of insufficient wearing comfort in existing rigid hinge eyeglasses.

[0005] On one hand, this utility model embodiment provides a method for connecting a mirror frame and a temple, including a first hinge component, a second hinge component, a pivot, and a reset assembly; The first hinge component is connected to the mirror frame, and the first hinge component is provided with a receiving cavity; The second hinge is connected to the temple of the mirror, and the second hinge is rotatably connected to the first hinge via the pivot. The reset assembly is disposed within the receiving cavity and includes an elastic element and a contact portion. The elastic element applies a spring force to the contact portion, causing the contact portion to tend to extend out of the receiving cavity. The second hinge is rotatable between a folded position and an open position; when the second hinge rotates from the folded position to the open position, the contact portion is pressed by the second hinge and moves into the receiving cavity and presses the elastic member; the elastic force of the elastic member is applied to the second hinge or the temple through the contact portion, so that the second hinge tends to rotate toward the folded position.

[0006] The reset assembly further includes a mounting portion, a guide portion, a first limiting portion, and a second limiting portion connected sequentially along a first direction; the mounting portion is fixedly connected to the cavity wall of the receiving cavity; the guide portion is connected to the mounting portion. The elastic element is sleeved on the guide portion and elastically expands and contracts between the first limiting portion and the second limiting portion; The contact portion is sleeved on the guide portion, and one end of the contact portion is provided with an inwardly protruding third limiting portion; One end of the elastic member abuts against the first limiting part, and the other end abuts against the third limiting part; The third limiting part cooperates with the second limiting part to prevent the contact part from disengaging from the guide part.

[0007] Optionally, the mounting portion includes a threaded section, which is connected to the cavity wall of the receiving cavity via threads, and the threaded section is connected to the first limiting portion.

[0008] Optionally, the mounting part, the guide part, the first limiting part, and the second limiting part are integrally formed.

[0009] Optionally, the contact portion is cylindrical and has a notch that extends radially and axially through the contact portion.

[0010] Optionally, the second limiting part is provided with a screw groove, which facilitates the insertion of a screwdriver.

[0011] Optionally, two reset components are provided, and the two reset components are spaced apart.

[0012] Optionally, the cross-section of the first limiting portion gradually decreases along the first direction from the second limiting portion to the fastening portion.

[0013] Optionally, the surface of the second limiting portion away from the first limiting portion is flush with the opening end face of the receiving cavity.

[0014] On the other hand, this utility model embodiment also provides a pair of glasses, including a frame, temples and the above-mentioned glasses hinge; The first hinge is connected to one of the frame or the temple, and the second hinge is connected to the other.

[0015] This embodiment achieves the automatic reset function of the eyeglass hinges through a reset component. Specifically, when a user wears the glasses, they need to rotate the temples with both hands to bring them close to their ears. At this time, when the temples rotate from a folded state to an open state, the second hinge component or the frame that rotates synchronously with the second hinge component will press the contact part, causing the elastic element to be compressed and store energy. When the temples are close to the ears and the hands are removed from the temples, the temples are no longer subject to external force. The elastic element releases its restoring force and applies this restoring force to the second hinge component through the contact part, creating a tendency for the temples to automatically return to their original position. This makes the temples fit the user's head more closely, ultimately achieving stable wearing of the glasses. It can provide a continuous and moderate clamping force when the user wears the glasses, effectively preventing them from slipping off. Attached Figure Description

Detailed Implementation

[0018] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Reference Figures 1 to 5An embodiment of this utility model provides an eyeglass hinge for connecting a frame 600 and a temple 700, including a first hinge member 100, a second hinge member 200, a pivot 300, and a reset assembly 500; the first hinge member 100 is fixedly connected to the frame 600 and has a receiving cavity 400; the second hinge member 200 is fixedly connected to the temple 700 and is rotatably connected to the first hinge member 100 via the pivot 300; the reset assembly 500 is disposed within the receiving cavity 400 and includes an elastic member 510 and a contact portion 5. 20. The elastic member 510 applies a spring force to the contact portion 520, so that the contact portion 520 tends to extend out of the receiving cavity 400; the second hinge member 200 is rotatable between the folded position and the open position; when the second hinge member 200 rotates from the folded position to the open position, the contact portion 520 is pressed by the second hinge member 200 and moves into the receiving cavity 400 and presses the elastic member 510; the spring force of the elastic member 510 is applied to the second hinge member 200 or the temple 700 through the contact portion 520, so that the second hinge member 200 tends to rotate toward the folded position.

[0020] Reference Figure 4 and Figure 5 In this embodiment, the automatic reset function of the eyeglass hinge is achieved through the reset component 500. Specifically, when the user wears the eyeglasses, they need to rotate the temples 700 with both hands to place them near their ears. At this time, when the temples 700 rotate from the folded state to the open state, the second hinge component 200 or the frame 600 that rotates synchronously with the second hinge component 200 will press the contact portion 520, causing the elastic component 510 to be compressed and store energy. When the temples 700 are placed near the ears and the hands are removed from the temples 700, the temples 700 are no longer subject to external force. The elastic component 510 releases its restoring force and applies this restoring force to the second hinge component 200 through the contact portion 520, creating a tendency for the temples 700 to automatically return to their original position. This makes the temples 700 fit the user's head more closely, ultimately achieving stable wearing of the eyeglasses. It can provide a continuous and moderate clamping force when the user wears the eyeglasses, effectively preventing them from slipping off.

[0021] Meanwhile, since the elastic element 510 is built into the receiving cavity 400, this embodiment greatly saves installation space compared to placing the elastic element 510 outside the frame 600.

[0022] In this embodiment, the elastic member 510 applies force to the temple via the contact portion 520, causing the temple to tend to rotate toward a folded state.

[0023] In other embodiments, the elastic member 510 applies force to the second hinge member 200 via the contact portion 520 to cause the temple to tend to rotate toward a folded state.

[0024] Reference Figures 3 to 5The reset assembly 500 further includes a mounting portion 530, a guide portion 540, a first limiting portion 550, and a second limiting portion 560 connected sequentially along a first direction. The mounting portion 530 is fixedly connected to the cavity wall of the receiving cavity 400. The guide portion 540 is connected to the mounting portion 530. An elastic member 510 is sleeved on the guide portion 540 and elastically expands and contracts between the first limiting portion 550 and the second limiting portion 560. A contact portion 520 is sleeved on the guide portion 540, and one end of the contact portion 520 is provided with an inwardly protruding third limiting portion 570. One end of the elastic member 510 abuts against the first limiting portion 550, and the other end abuts against the third limiting portion 570. The third limiting portion 570 and the second limiting portion 560 engage in a stop-fitting cooperation to prevent the contact portion 520 from disengaging from the guide portion 540.

[0025] In one embodiment, the mounting portion 530 includes a threaded section that is connected to the cavity wall of the receiving cavity 400 via threads, and the threaded section is connected to the first limiting portion 550. Using a threaded connection to fix the mounting portion 530 to the receiving cavity 400 offers advantages such as simple assembly, reliable connection, and easy disassembly and maintenance. The threaded connection provides sufficient preload to ensure that the reset assembly 500 will not loosen due to vibration or frequent use during operation. Simultaneously, the standardized threading process reduces manufacturing costs and improves the product's maintainability and replaceability.

[0026] In one embodiment, the mounting portion 530, the guide portion 540, the first limiting portion 550, and the second limiting portion 560 are integrally formed. This integral forming process significantly reduces the number of parts, simplifies the assembly process, improves production efficiency and product consistency, enhances the overall structural strength and stability, and reduces the risk of failure due to loose parts, making the product more durable and reliable.

[0027] In one embodiment, the contact portion 520 is cylindrical and has a notch 521 that extends radially and axially through the contact portion 520. In this embodiment, the receiving cavity 400 is a circular blind hole structure; therefore, the contact portion 520 is also correspondingly cylindrical. A gap exists between the outer wall of the contact portion 520 and the outer wall of the receiving cavity 400 to facilitate reciprocating sliding of the contact portion 520. The cross-sectional shape of the inner hole of the contact portion 520 is the same as that of the guide portion 540, allowing the contact portion 520 to be fitted onto the guide portion 540 and slide along the length of the guide portion 540. In this embodiment, the guide portion 540 is a round rod, and the inner hole of the contact portion 520 is a round hole. In other embodiments, the guide portion 540 can be a square rod, and the inner hole of the contact portion 520 can also be a square hole.

[0028] This embodiment also endows the contact portion 520 with a certain elastic deformation capacity through the notch 521, enabling it to better adapt to the movement trajectory and contact state of the second hinge component 200, effectively reducing contact impact and friction noise. At the same time, this design also facilitates installation and positioning during the assembly process, improving the convenience of production assembly. In other embodiments, the receiving cavity 400 is a square blind hole structure, so the contact portion 520 is also correspondingly cylindrical, and there is a gap between the outer wall of the contact portion 520 and the outer wall of the receiving cavity 400 so that the contact portion 520 can slide back and forth.

[0029] In one embodiment, the second limiting part 560 is provided with a screw groove 561, which facilitates the insertion of a screwdriver. The screw groove 561 greatly simplifies the installation and disassembly process, allowing the operation to be completed using standard tools, reducing maintenance difficulty and cost, and providing convenience for rapid assembly.

[0030] In one embodiment, two reset components 500 are provided, spaced apart. Using two reset components 500 provides a more balanced and stable clamping force distribution, effectively reducing the deflection and imbalance problems that may occur due to single-point force application. This makes the opening and closing action of the temple 700 smoother and more uniform, significantly improving the comfort and reliability of the product.

[0031] In one embodiment, the cross-section of the first limiting portion 550 gradually decreases along the first direction from the second limiting portion 560 to the fastening portion. In this embodiment, the integral formed by the mounting portion 530 and the first limiting member is the same as the existing screw structure, and therefore it has the advantages of a screw structure, and can be stably fixed in the receiving cavity 400.

[0032] In one embodiment, the surface of the second limiting portion 560 that is away from the first limiting portion 550 is flush with the open end face of the receiving cavity 400. By precisely controlling the flushing of the surface of the second limiting portion 560 that is away from the first limiting portion 550 with the open end face of the receiving cavity 400, the neatness and aesthetics of the reset assembly 500 after installation are ensured, and structural problems such as protrusions or depressions are avoided.

[0033] On the other hand, this utility model embodiment also provides a pair of glasses, including a frame 600, temples 700 and the above-mentioned glasses hinges; a first hinge member 100 is connected to the frame 600, and a second hinge member 200 is connected to the temples 700.

[0034] In summary, this invention provides eyeglasses with a hinge that offers excellent wearing comfort and ease of use. The innovative flexible hinge design automatically adapts to different head shapes, providing just the right clamping force. This ensures stability while avoiding the pressure or looseness caused by the fixed clamping force of traditional eyeglasses.
