Description

Technical Field

[0001] This disclosure relates to eyeglasses, and more particularly to a rotating mechanism for inward and outward folding temples. Background Technology

[0002] Eyeglasses are primarily used to improve vision, protect the eyes, or for decorative purposes. Examples include prescription glasses, farsighted glasses, reading glasses, astigmatism glasses, plano glasses, goggles, swimming goggles, night vision goggles, gaming glasses, windproof goggles, sunglasses, toy glasses, and AR smart glasses. More and more fields require various types of eyeglasses, making them an indispensable tool for many people's work and daily lives. However, most existing eyeglasses have non-adjustable temples relative to the frame. The temples cannot be adjusted outwards or inwards relative to the frame; they can only be forcibly bent outwards or inwards. This can easily lead to problems such as the glasses being too loose, too tight, unstable, wobbling, or slipping during wear. The fit, performance, and comfort are poor, and the safety, stability, and reliability are low, failing to meet the diverse needs of different users and hindering the product's application and development.

[0027] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only some, not all, of the embodiments of this disclosure, and are used merely to explain this disclosure and are not intended to limit it. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0029] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] See Figures 1-10The diagram schematically illustrates a gripping and rotating mechanism for an inwardly and outwardly foldable temple according to the present disclosure, comprising a first connecting shell 1, a first rotating plate 3, a first rotating shaft 4, and a first friction element 5. The first rotating plate 3 is used to connect with the corresponding temple. The first connecting shell 1 can cooperate with the corresponding frame, for example, the first connecting shell 1 is fixed relative to or fixedly connected to the frame. The first connecting shell 1 is hinged to the first rotating shaft 4, that is, the first rotating shaft 4 can rotate relative to the first connecting shell 1. The first rotating plate 3 is connected to the first rotating shaft 4, and the first rotating plate 3 and the first rotating shaft 4 are fixed in the circumferential direction, so that the first rotating plate 3 and the first rotating shaft 4 can rotate synchronously together. The first rotating shaft 4 and the first rotating plate 3 can rotate outward relative to the first connecting shell 1 through the first rotating shaft 4. The first rotating shaft 4 and the first rotating plate 3 can also rotate inward relative to the first connecting shell 1 through the first rotating shaft 4. The first friction element 5 cooperates with the first rotating shaft 4. During the rotation of the first rotating shaft 4, the first friction element 5 can provide frictional damping force for the rotation of the first rotating shaft 4, so that the first rotating shaft 4 can stop at will and self-lock.

[0031] During use, the first rotating plate 3 is connected to the corresponding temple, and the first connecting shell 1 is fixed relative to the frame. When it is necessary to fold the temple inward, such as... Figure 5 As shown, the first rotating plate 3 and the temple are rotated inward as a whole. The first rotating plate 3 and the first rotating shaft 4 rotate synchronously together. The first friction element 5 provides frictional damping force for the rotation of the first rotating shaft 4, so that the outward rotation of the first rotating plate 3 and the temple can be stopped at will and self-locked. Similarly, when it is necessary to fold the temple outward, as shown... Figure 7 As shown, the first rotating plate 3 and the temple are rotated outwards as a whole. The first rotating plate 3 rotates synchronously with the first rotating shaft 4. The first friction element 5 provides frictional damping force for the rotation of the first rotating shaft 4, allowing the outward rotation of the first rotating plate 3 and the temple to stop at will and self-lock. This enables the temple to fold outwards and backwards, making operation convenient and quick. The structure is simple, compact, and stable, with high stability and reliability. It can be adjusted according to different users, such as according to the size of the face, specific face shape, and nose bridge height. Users are less likely to experience problems such as being too loose, too tight, not secure, shaking, or sliding during wearing. It has a better fit, performance, and comfort, and can better meet the needs of different users, with a wide range of applications. The angle at which the first rotating plate 3 and the temple fold outwards relative to the frame can be 10°, 15°, or any other suitable angle. The angle at which the first rotating plate 3 and the temple rotate inwards relative to the frame can be 80°, 90°, or any other suitable angle.

[0032] A first limiting rotating seat 2 is provided on the first connecting shell 1. The first limiting rotating seat 2 is hinged to the first rotating shaft 4, meaning that the first limiting rotating seat 2 and the first rotating shaft 4 can rotate relative to each other in the circumferential direction. A first elastic element 11 is provided on the first connecting shell 1, which cooperates with one end of the first limiting rotating seat 2. The other end of the first limiting rotating seat 2 cooperates with the first connecting shell 1. A first pushing part 41 is provided on the first rotating shaft 4, and a first stop block 21 corresponding to the first pushing part 41 is provided on the first limiting rotating seat 2. In the initial state, such as Figures 3-4 As shown, the first connecting shell 1 is relatively fixed. Under the action of the first elastic element 11, one end of the first limiting rotating seat 2 cooperates with the first elastic element 11, and the other end of the first limiting rotating seat 2 presses against the first connecting shell 1, so that the first limiting rotating seat 2 can only rotate outward and cannot rotate outward. At the same time, the first pushing part 41 of the first rotating shaft 4 cooperates with the first stop 21 of the first limiting rotating seat 2. When the first rotating plate 3 is rotated outward relative to the first connecting shell 1 from the initial state, as Figures 7-8 As shown, the first rotating plate 3 rotates synchronously with the first rotating shaft 4. The first rotating shaft 4 pushes the first stop 21 through the first pushing part 41, causing the first limiting rotating seat 2 to rotate outward synchronously with the first rotating shaft 4. At the same time, the outward rotation of the first limiting rotating seat 2 causes the first elastic element 11 to elastically deform. When the first rotating plate 3 is released, the elastic restoring force of the first elastic element 11 also facilitates the reset of the first limiting rotating seat 2 and the first rotating plate 3. When the first rotating plate 3 is rotated inward relative to the first connecting shell 1 from its initial state, as... Figures 5-6 As shown, the first limiting rotating seat 2 cannot rotate inward. The first limiting rotating seat 2 remains stationary, and the first rotating plate 3 and the first rotating shaft 4 rotate synchronously together. At this time, the first pushing part 41 and the first stop block 21 are separated and do not contact each other.

[0033] A first stop 42 is provided on the first rotating shaft 4, and a second stop 22 corresponding to the first stop 42 is provided on the first limiting rotating seat 2. During the process of the first rotating plate 3 rotating outward relative to the first connecting shell 1 from the initial state, the first stop 42 and the second stop 22 are separated and do not contact each other; when the first rotating plate 3 is rotated inward relative to the first connecting shell 1 from the initial state, the first pushing part 41 and the first stop 21 are separated and do not contact each other. When the first stop 42 and the second stop 22 cooperate, the first rotating shaft cannot continue to rotate, that is, the first rotating plate 3 cannot continue to rotate inward, thereby limiting the maximum angle of inward rotation of the first rotating plate 3 and the temple, making it safer and more reliable.

[0034] The number and arrangement of the first stop 42 and the second stop 22, as well as the number and arrangement of the first stop 42 and the second stop 22, are determined according to the specific situation. There can be one, two or more first stop 42 and second stop 22. For example, the first stop 42 and the second stop 22 can be arranged in two symmetrical pairs. The force is more even, more stable and reliable.

[0035] The first limiting rotary seat 2 is provided with a first through hole 23 connected to the first rotating shaft 4. The first stop 21 and the second stop 22 are protrusions provided in the first through hole 23. The first stop 21 and the second stop 22 are arranged along the axial direction of the first through hole 23. The first stop part 42 and the first push part 41 are planes provided on the first rotating shaft 4. The first stop 21 and the second stop 22 are arranged along the axial direction of the first rotating shaft 4. The structure is simple and stable, and the operation is more convenient. The first stop 21 and the second stop 22 can also be integrally formed with the first limiting rotary seat 2, making the structure more stable and reliable.

[0036] The first elastic element 11 is a spring sheet. One end of the first elastic element 11 is fixed to the first connecting shell 1, for example, by welding or by fasteners such as screws. The other end of the first elastic element 11 is suspended and cooperates with the first limiting rotating seat 2. The structure is simple and easy to operate. One end of the first limiting rotating seat 2 is provided with a first pressing part 24 that cooperates with the first elastic element 11, and the other end of the first limiting rotating seat 2 is provided with a second pressing part 25 that cooperates with the first connecting shell 1. The first connecting shell 1 is provided with a third stop 12 that cooperates with the second pressing part 25. In the initial state, one end of the first elastic element 11 acts on the first pressing part 24, and the second pressing part 25 presses against the third stop 12, so that the first limiting rotating seat 2 can only rotate outward and cannot rotate inward. The first pressing part 24 and the second pressing part 2 can be a plane provided on the first limiting rotating seat 2, and the third stop 12 can also be integrally formed with the first connecting shell 1, making the structure simpler, more stable and reliable.

[0037] The first friction element 5 is a friction plate, and it has a second through hole 51 connected to the first rotating shaft 4. The first rotating shaft 4 rotates along the circumference of the second through hole 51, generating frictional damping force, which allows the rotation of the first rotating shaft 4 to stop at will and self-lock. The first rotating shaft 4 and the second through hole 51 are interference-fitted, which ensures more stable frictional damping force. The structure is simple, stable, and easy to operate. The first friction element 5 can be one or more, stacked and pressed together. It can be appropriately increased or decreased according to actual needs, making assembly and adjustment more convenient.

[0038] The first friction element 5 can be fixed to the first connecting shell 1, or it can rotate synchronously with the first limiting rotating seat 2, for example, the first friction element 5 can be fixedly connected to the first limiting rotating seat 2. The synchronous rotation of the first limiting rotating seat 2 and the first friction element 5 facilitates better repositioning of the first limiting rotating seat 2, the first rotating shaft 4, and the first rotating plate 3. The first limiting rotating seat 2 is provided with a first connecting rod 26 connected to the first friction element 5, and the first friction element 5 is provided with a through hole connected to the first connecting rod 26. Under the constraint of the first connecting rod 26 and the first rotating shaft 4, the first limiting rotating seat 2 and the first friction element 5 will not rotate relative to each other, resulting in a simpler and more compact structure. The first connecting rod 26 can be integrally formed with the first limiting rotating seat 2, making the structure more stable and reliable. A set of first friction elements 5 is provided on each side of the first limiting rotating seat 2. Each set of first friction elements 5 can be multiple, stacked sequentially. Each set of first friction elements 5 presses against the side of the first limiting rotating seat 2. Each set of first friction elements 5 corresponds to a first rotating shaft 4. The two first rotating shafts 4 are symmetrically arranged on both sides of the first limiting rotating seat 2, resulting in more uniform force distribution and higher stability and reliability. The first connecting shell 1 is provided with a first groove 14 that cooperates with the first limiting rotating seat 2, the first elastic element 11, and the first friction elements 5, making the structure more compact and stable. The first limiting rotating seat 2 and the first elastic element 11 are located in the first groove 14, which can also prevent the first limiting rotating seat 2 and the first elastic element 11 from shaking or moving axially. The frictional damping force between the first elastic element 11 and the first rotating shaft 4 can also limit the axial movement of the first rotating shaft 4.

[0039] The second through hole 51 is provided with a first notch 52, which extends axially through the second through hole 51. The first notch 52 facilitates better connection between the first rotating shaft 4 and the second through hole 51, making operation more convenient. The second through hole 51 is also provided with a first friction structure 53, which can be a protrusion, an arc surface, a groove, etc., to better provide frictional damping force.

[0040] A fourth stop 13 is provided on the first connecting shell 1, and a first impact block 31 corresponding to the fourth stop 13 is provided on the first rotating plate 3. When the first rotating plate 3 is rotated outward, the first impact block 31 will hit the fourth stop 13, preventing the first rotating plate 3 from rotating outward. This limits the maximum outward rotation angle of the first rotating plate 3 relative to the first connecting shell 1. The structure is simple, stable, and safer and more reliable. The fourth stop 13 can be integrally formed with the first connecting shell 1, and the first impact block 31 can be integrally formed with the first rotating plate 3, making the structure more stable and reliable.

[0041] The first rotating plate 3 and the first rotating shaft 4 are fixed circumferentially. The first connecting shell 1 has a fourth through hole that is hinged to the first rotating shaft 4. The first rotating shaft 4 can have a first flat section along its axial direction. A second flat section that mates with the first flat section can be located within the fourth through hole. This flat section structure fixes the first rotating plate 3 and the first rotating shaft 4 circumferentially, resulting in a simple structure and convenient operation. One end of the first rotating shaft 4 can also have a first flange, and the first flat section can be located on the first flange, making the structure more compact and stable. Alternatively, the first rotating plate 3 and the first rotating shaft 4 can also be fixed circumferentially using pins, keys, or other methods.

[0042] Compared with the prior art, the advantages of this disclosure are: it can realize the outward and inward folding of the temples; the first friction member 5 provides frictional damping force for the rotation of the first rotating shaft 4, so that the outward rotation of the first rotating plate 3 and the temples can be stopped at will and self-locked; the first friction member 5 also facilitates assembly, adjustment, and restriction of the axial movement of the first rotating shaft 4; the first stop part 42 cooperates with the second stop block 22 to limit the maximum angle of inward rotation of the temples; the fourth stop block 13 cooperates with the first impact block 31 to limit the maximum angle of outward rotation of the temples; the first elastic member 11 facilitates the reset of the temples after outward folding; the operation is convenient and quick; the structure is simple, compact, and stable; and the safety, stability, and reliability are high. It can be adjusted according to different users, such as face size, face shape, and nose bridge height. Users are less likely to experience problems such as being too loose, too tight, not secure, shaking, or slipping during wear. It has a better fit, performance, and comfort, and can better meet the needs of different users. It is easy to apply to various types of glasses such as myopia glasses, hyperopia glasses, reading glasses, astigmatism glasses, plano glasses, goggles, swimming goggles, night vision glasses, gaming glasses, windproof glasses, sunglasses, toy glasses, sunglasses, AR smart glasses, etc., with a wide range of applications, which enhances the product's competitiveness and expands its application and development.

[0043] The above descriptions are merely some embodiments of this disclosure, used only to illustrate the technical solutions of this disclosure, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above descriptions without departing from the inventive concept of this disclosure, and all such improvements and substitutions should fall within the protection scope of the appended claims. In such cases, all details can be replaced with equivalent elements, and materials, shapes, and sizes can also be arbitrary.
