The mechanism includes a first bracket, on which are mounted a first cam, a second cam, a first elastic element, a first rotating shaft, and a first support member. The first bracket connects to the corresponding eyeglass frame. The first rotating shaft is fixedly connected to the first cam and hinged to the corresponding first temple. Under the action of the first elastic element, the first cam engages with the second cam. Rotation of the first cam relative to the second cam allows the first temple to rotate up and down relative to the frame. The first temple can rest against the first support member as a fulcrum and rotate outward around the first rotating shaft. Simultaneously, axial movement of the first cam causes elastic deformation of the first elastic element. This disclosure enables outward folding of the first temple and rotation of the frame, offering convenient and quick operation, better fit and comfort for the user, and better meeting the needs of different users.

Description

Technical Field

[0001] This disclosure relates to eyeglasses, and more particularly to a rotating mechanism for foldable temples and a rotatable frame. 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 relative to the frame; they can only be forcibly bent outwards. Furthermore, the temples cannot rotate relative to the frame. This can 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.

The first temple can cooperate with the first support element. The first cam can slide axially and rotate circumferentially. The second cam is fixed circumferentially. Under the action of the first elastic element, the first cam and the second cam cooperate. The rotation of the first cam relative to the second cam allows the first temple to rotate up and down relative to the frame, i.e., the frame can rotate. The first temple can rest against the first support element as a fulcrum and rotate outward around the first rotating shaft.

The first cam can rotate relative to the first connecting shaft in the circumferential direction, and the second cam is fixed in the circumferential direction of the first connecting shaft. The first cam and the second cam can slide along the first connecting shaft in the axial direction, and the axial sliding of the first cam and the second cam can cause the first elastic element to elastically deform.

Detailed Implementation

[0023] 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.

[0024] In the description of this disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," "outer," "both ends," "both sides," "bottom," and "top," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the elements referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. Furthermore, the terms "first," "second," "upper-level," "lower-level," "primary," and "secondary," etc., are used for descriptive purposes only and can be simply used to more clearly distinguish different components, and should not be construed as indicating or implying relative importance.

[0025] 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.

[0026] See Figures 1-6 The diagram schematically illustrates a rotating mechanism for a foldable temple and rotatable frame according to the present disclosure, comprising a first bracket 1. The first bracket 1 is provided with a first cam 2, a second cam 3, a first elastic element 4, a first pivot 5, and a first support element 11. The first bracket 1 is used to connect to the corresponding frame, for example, by means of snap-fit ​​connection, welding connection, or fastener connection. The first pivot 5 is fixedly connected to the first cam 2, for example, by means of welding connection, fastener connection, or integral molding. The first pivot 5 is used to hinge to the corresponding first temple. The first temple is not shown in the diagram. The first temple can cooperate with the first support element 11. The first cam 2 cooperates with the second cam 3. The first elastic element 4 cooperates with the first cam 2 and / or the second cam 3. The first cam 2 can slide axially and can rotate circumferentially. The second cam 3 is fixed circumferentially and can be axially fixed and can also slide axially. Under the action of the first elastic element 4, the first cam 2 and the second cam 3 are matched. The cam surfaces of the first cam 2 and the second cam 3 interact with each other. The axial movement of the first cam 2 causes the first elastic element 4 to elastically deform. The axial sliding of the first cam 2 requires at least overcoming the axial force of the first elastic element 4 on the first cam 2, while the rotation of the first cam 2 requires at least overcoming the frictional damping force of the second cam 3 on the first cam 2.

[0027] During use, the first bracket 1 is connected to the corresponding frame, and the first rotating shaft 5 is hinged to the corresponding first temple. When the first temple is opened relative to the frame, the first elastic element 4, the first cam 2, and the second cam 3 ensure that the first temple is stable relative to the frame and will not wobble outward or up and down. When the first temple needs to be folded outward, it is rotated outward, with the first temple resting against the first support 11 as a fulcrum. The first temple rotates outward around the first rotating shaft 5, and at the same time, the first temple drives the first cam 2 to move axially through the first rotating shaft 5. The axial movement of the first cam 2 causes the first elastic element 4 to elastically deform. After the first temple is released, the first elastic element 4 can drive the first cam 2 and the first temple to return to their original positions. When the first temple needs to be moved up and down relative to the frame... When rotating (i.e., rotating the frame), the first temple rotates up and down relative to the frame. The first temple drives the first cam 2 to rotate via the first pivot 5. The first elastic element 4 and the second cam 3 generate frictional damping force for the rotation of the first cam 2, allowing the first temple to stop rotating up and down at will and to self-lock. This enables the outward folding of the first temple and the rotation of the frame. The operation is convenient and quick, the structure is compact and stable, and the stability and reliability are high. 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 slipping during wear. It has a better fit, performance, and comfort, and can better meet the needs of different users, with a wide range of applications. The outward folding angle of the first temple can be 10°, 15°, 20°, or any other suitable angle, and the angle of the first temple rotating up and down relative to the frame can be 3°, 5°, 7°, or any other suitable angle.

[0028] A first connecting shaft 6 is provided on the first bracket 1. A first cam 2 and a second cam 3 are sequentially arranged on the first connecting shaft 6. The first cam 2 can rotate relative to the first connecting shaft 6 in the circumferential direction, while the second cam 3 is fixed in the circumferential direction to the first connecting shaft 6. The first cam 2 and the second cam 3 can slide axially along the first connecting shaft 6. The axial sliding of the first cam 2 and the second cam 3 can cause the first elastic element 4 to elastically deform. The first connecting shaft 6 and the second cam 3 can be fixed in the circumferential direction by means of a flat structure, a key structure, a slider and a groove structure, etc. When the first temple rotates outward, the first temple abuts against the first support member 11 as a fulcrum, and the first temple rotates outward around the first rotating shaft 5. At the same time, the first temple drives the first cam 2 and the second cam 3 to move axially together through the first rotating shaft 5. The axial sliding of the first cam 2 and the second cam 3 causes the first elastic element 4 to elastically deform. After the first temple is released, the first elastic element 4 drives the first cam 2, the second gear 3, the first temple, etc. to return to their original positions. The structure is simple and compact, easy to operate, and more stable and reliable.

[0029] The first bracket 1 is provided with a third limiting member 13 for limiting the axial sliding distance of the second cam 3. When the first temple rotates outward, the first temple abuts against the first support member 11 as a fulcrum, and the first temple rotates outward around the first rotating shaft 5. At the same time, the first temple drives the first cam 2 and the second cam 3 to move axially together through the first rotating shaft 5. The axial sliding of the first cam 2 and the second cam 3 causes the first elastic member 4 to elastically deform. When the second cam 3 cooperates with the third limiting member 13, the second cam 3 cannot continue to slide axially, thereby preventing the first temple from folding outward, thus limiting the maximum angle of the first temple folding outward, making it safer and more reliable. The third limiting member 13 can be a separate part installed on the first bracket 1, or the third limiting member 13 can be a limiting plane integrally formed on the first bracket 1, with the shaft end plane of the second cam 2 pressing against the third limiting member 13 for limiting.

[0030] A first limiting member 61 is provided at one end of the first connecting shaft 6, and a second limiting member 62 is provided at the other end of the first connecting shaft 6. A through hole is provided on the first bracket 1 to connect with the first connecting shaft 6. Both ends of the first connecting shaft 6 pass through the corresponding through hole, and then the first limiting member 61 and the second limiting member 62 are used to lock the two ends of the first connecting shaft 6 respectively, thereby axially fixing the first connecting shaft 6. The first limiting member 61 can be a shaft elastic retaining ring, a lock nut, etc., and the second limiting member 62 can be an elastic retaining ring, a lock nut, a shaft shoulder, or a flange, etc. The structure is more stable and reliable, and the operation is more convenient. The first limiting member 61 is a flange integrally formed on the first connecting shaft 6, and the second limiting member 62 is a first elastic retaining ring. A first groove that mates with the first elastic retaining ring is provided on the first connecting shaft 6, making the structure more compact and stable, and the operation more convenient. The first bracket 1 may also be provided with a groove that cooperates with the first limiting member 61. The first bracket 1 and the first connecting shaft 6 may also adopt a flat structure, so that the first connecting shaft 6 will not rotate, making the structure more stable and reliable.

[0031] The first elastic element 4 is a compression spring sleeved on the first connecting shaft 6. The second cam 3 is located between the first elastic element 4 and the first cam 2. One end of the first elastic element 4 presses against the second cam 3, and the other end of the first elastic element 4 presses against the first bracket 1, making operation more convenient. The first bracket 1 is provided with a first groove 12, in which the first cam 2, the second cam 3, and the first elastic element 4 are located, facilitating assembly, disassembly, and other operations, and reducing weight.

[0032] The first rotating shaft 5 is connected to the first temple via the first connecting arm 7. The first rotating shaft 5 and the first connecting arm 7 are hinged together. The first connecting arm 7 and the first temple are fixedly connected. The first connecting arm 7 and the first temple can be connected by fasteners such as screws, snap-fit ​​connections, or other suitable connection methods in the prior art. The first connecting arm 7 is provided with a first protrusion 71 that cooperates with the first support member 11. The first protrusion 71 abuts against the first support member 11 as a fulcrum, and the first connecting arm 7 rotates outward around the first rotating shaft 5. At the same time, the first cam 2 moves axially, and the axial movement of the first cam 2 causes the first elastic member 4 to elastically deform. When the first temple rotates outward, as... Figure 3 , Figure 5 As shown, the first protrusion 71 of the first connecting arm 7 abuts against the first support member 11 as a fulcrum, and the first connecting arm 7 rotates outward around the first rotating shaft 5. At the same time, the first connecting arm 7 drives the first cam 2 and the second cam 3 to move axially together through the first rotating shaft 5, and the first cam 2 and the second cam 3 slide axially to cause the first elastic member 4 to elastically deform, thereby realizing the outward folding of the first temple. The first connecting arm 7 can be part of the rotating mechanism of this application, or the first connecting arm 7 can be part of the first temple.

[0033] The first connecting arm 7 is provided with two fourth limiting members 72, which are arranged vertically. The first bracket 1 is provided with two fifth limiting members 14, which are arranged vertically and correspond one-to-one with the two fourth limiting members 72. When the first temple rotates upward relative to the frame, as... Figure 4 , Figure 6 As shown, when the first temple rotates up and down relative to the frame, the first connecting arm 7 drives the first cam 2 to rotate via the first rotating shaft 5. The first elastic element 4 and the second cam 3 generate frictional damping force for the rotation of the first cam 2, allowing the first temple to stop rotating up and down at will and to self-lock. When the upper fourth limiting element 72 engages with the upper fifth limiting element 14, the first temple cannot continue to rotate upward (i.e., the frame cannot continue to rotate upward). The same applies when the first temple rotates downward relative to the frame, thus limiting the maximum angle of the first temple's up and down rotation relative to the frame, making it safer and more reliable. The two fifth limiting elements 14 are located between the two fourth limiting elements 72, making operation more convenient. The fourth limiting element 72 can be integrally formed with the first connecting arm 7, and the fifth limiting element 14 can be integrally formed with the first bracket 1. The fifth limiting element 14 and the fourth limiting element 72 can adopt a planar structure.

[0034] The first rotating shaft 5 is welded to the first cam 2. The end of the first cam 2 away from the second cam 3 is provided with a connecting part. The connecting part is provided with a hole that connects to the first rotating shaft 5. The first rotating shaft 5 is inserted into the hole and welded, making the structure more stable and reliable.

[0035] The first connecting arm 7 is provided with a first ear plate 73 that is hinged to the first rotating shaft 5. One end of the first rotating shaft 5 is fixedly connected to the first cam 2, and the other end of the first rotating shaft 5 can be locked by an elastic retaining ring, etc., making operation more convenient. There are two symmetrically arranged first ear plates 73, and there are also two symmetrically arranged first rotating shafts 5. The first ear plates 73 and the first rotating shafts 5 correspond one-to-one. The first cam 2 is located between the two first rotating shafts 5, and the two first rotating shafts 5 are located between the two first ear plates 73. The two first rotating shafts 5 are coaxial, resulting in more even force distribution and a more stable and reliable structure.

[0036] Compared with the prior art, the advantages of this disclosure are as follows: When it is necessary to fold the first temple outward, the first temple is rotated outward, the first protrusion 71 of the first connecting arm 7 abuts against the first support member 11 as a fulcrum, and the first connecting arm 7 rotates outward around the first rotating shaft 5. At the same time, the first connecting arm 7 drives the first cam 2 and the second cam 3 to move axially together through the first rotating shaft 5, and the axial movement of the first cam 2 and the second cam 3 causes the first elastic member 4 to elastically deform. After the first temple is released, the first elastic member 4 can drive the first cam 2, the second cam 3, the first temple, etc. to return to their original positions. The third limiting member 13 can also limit the maximum angle of the first connecting arm 7 folding outward. When it is necessary to rotate the first temple up and down relative to the frame (i.e., rotate the frame), the first temple is rotated up and down relative to the frame. The first connecting arm 7 drives the first cam 2 to rotate through the first rotating shaft 5. The first elastic member 4 and the second cam 3 can generate frictional damping force for the rotation of the first cam 2, so that the first temple can rotate up and down. It can stop and lock at will. The fourth limiter 72 and the fifth limiter 14 work together to limit the maximum angle of the first temple's vertical rotation. The structure is simple, compact, and stable, and the operation is convenient and quick. It can realize the outward folding of the first temple and the rotation of the frame. It has high safety, stability and reliability. It can be adjusted according to different users, such as according to the size of the user's face, specific face shape, nose bridge height, etc. During the wearing process, the user is not likely to experience problems such as being too loose, too tight, not secure, shaking or sliding. It has better fit, performance and comfort, and can better meet the needs of different users. It is easy to apply to various kinds 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 and so on. The wide range of applications enhances the product's competitiveness and expands the application and development of the product.

[0037] 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.
