DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are part of the embodiments of the present disclosure, rather than all of the embodiments, and are only used to explain the present disclosure, and are not used to limit the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0028] In the description of the present disclosure, it should be noted that the terms "center", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside", "two ends", "both sides", "bottom", "top" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present 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, and therefore cannot be understood as limitations on the present disclosure. In addition, the terms "first", "second", "superior", "inferior", "primary", "secondary" and the like are used for descriptive purposes only, and can simply be used to more clearly distinguish different components, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0030] See also Figures 1 to 9 As shown, a semi-automatic eyeglass leg mechanism according to the present disclosure is schematically shown, comprising an eyeglass leg body 1, a rotating mechanism 2, a cam assembly 3 and a base 4. The rotating mechanism 2 is arranged at one end of the eyeglass leg body 1, the rotating mechanism 2 is hinged to the base 4, the base 4 is used to be connected to the corresponding eyeglass frame, the cam assembly 3 cooperates with the rotating mechanism 2, and a first elastic member 7 cooperating with the cam assembly 3 is arranged on the rotating mechanism 2. The cam assembly 3 can rotate synchronously with the rotating mechanism 2, and the first elastic member 7 can interact with the cam assembly 3.

[0031] The two eyeglass leg mechanisms are symmetrically mounted on both sides of the frame through the base 4. Figures 3 to 5As shown, when the temple body 1 is opened relative to the frame, an outward force is first applied to the temple body 1, and the temple body 1 rotates relative to the base 4 through the rotating mechanism 2, and the cam assembly 3 rotates synchronously with the rotating mechanism 2. At the same time, the first elastic member 7 interacts with the cam assembly 3, and the first elastic member 7 is compressed. As the cam assembly 3 rotates to a specified position, such as after the temple body 1 rotates 30°, 45° or 60° relative to the frame or the base 4, at this time, there is no need to apply a force to the temple body 1, but the first elastic member 7 elastically recovers to drive the cam assembly 3 to rotate, and the cam assembly 3 drives the rotating mechanism 2 to move synchronously, so that the temple body 1 is eventually automatically opened. When the temple body 1 is closed relative to the frame, similarly, an inward force is first applied to the temple body 1, and as the cam assembly 3 rotates to a specified position, the first elastic member 7 elastically recovers to drive the cam assembly 3 to rotate, so that the temple body 1 is eventually automatically closed, thereby realizing the temple main body 1 The temple body 1 can be semi-automatically opened and closed, and after the two temple mechanisms are opened relative to the frame, the user can also apply an outward force to the two temple bodies 1, and the temple bodies 1 are rotated outward relative to the frame through the rotating mechanism 2. The principle is the same as above, and the cam assembly 3 rotates synchronously with the rotating mechanism 2. At the same time, the first elastic member 7 interacts with the cam assembly 3, and the first elastic member 7 is compressed, so that the first elastic member 7 elastically exerts a reverse force on the temple body 1, so that the temple body 1 is elastically expanded outward relative to the base 4 and can automatically rebound and reset, such as elastically expanding outward by 5°, 10°, 15°, etc., which is convenient for different users to make different adjustments, such as adjusting according to the size of the face, specific face shape, etc., to meet the use needs of different users, and is suitable for various glasses such as myopia glasses, goggles, swimming goggles, night vision goggles, e-sports glasses, sunglasses, sunglasses, smart glasses, AR glasses, etc.

[0032] The cam assembly 3 includes a first cam 31 and a second cam 32 that match each other. The first elastic member 7, the first cam 31 and the second cam 32 are sequentially arranged along the axial direction of the rotating mechanism 2. The first cam 31 and the second cam 32 are coaxial with the rotating mechanism 2 respectively. One end of the first elastic member 7 presses against the first cam 31, and the other end of the first elastic member 7 can press against the rotating mechanism 2, the base 4 or other corresponding end faces. The second cam 32 is fixed, and the first cam 31 rotates synchronously with the rotating mechanism 2. The rotating first cam 31 interacts with the second cam 32 and the first elastic member 7. The first elastic member 7 can provide elastic pressure for the first cam 31 to ensure that the first cam 31 and the second cam 32 match each other. Figures 3 to 5As shown, when the temple body 1 is opened relative to the frame, referring to the above, an outward force is first applied to the temple body 1, and the first cam 31 rotates synchronously with the rotating mechanism 2, and the cam portion of the first cam 31 interacts with the cam portion of the second cam 32. At this time, the first cam 31 moves axially in a direction away from the second cam 32, and the first elastic member 7 is further compressed. As the first cam 31 rotates to a specified position, such as after the temple body 1 rotates 30°, 45° or 60° relative to the frame or the base 4, the cam portion of the first cam 31 interacts with the cam portion of the second cam 32, and the first cam 31 moves axially in a direction close to the second cam 32. At this time, there is no need to apply a force to the temple body 1, but the first elastic member 7 elastically recovers to drive the first cam 31 to move axially. At the same time, under the action of the second cam 32, the first cam 31 rotates until the temple body 1 is finally opened. When the temple body 1 is closed relative to the frame or when the temple body 1 elastically expands outward relative to the base 4, the same reason applies and is not described in detail.

[0033] The rotating mechanism 2 includes a first rotating shaft 21, a first mounting groove 41 matching with the first rotating shaft 21 is provided on the base 4, a first connecting plate 22 connected with the temple body 1 is provided on one side of the first rotating shaft 21, the first connecting plate 22 and the temple body 1 can be connected by fasteners such as screws, or can be connected by welding, etc., a first hole body 211 is provided on the first rotating shaft 21 along its axial direction, the first cam 31 and the first elastic member 7 are located in the first hole body 211, the second cam 32 is fixed in the first mounting groove 41, and the first cam 31 and the first elastic member 7 are located in the first hole body 211. The second cam 32 is located at one end of the first rotating shaft 21. A first slider 212 is provided in the first hole 211 to match the first slide groove 311 on the first cam 31. The first slide groove 311 is provided along the axial direction of the first cam 31. The first slider 212 and the first slide groove 311 usually correspond to each other one by one. The number and arrangement of the first slider 212 and the first slide groove 311 are determined according to the specific situation. The first slider 212 and the first slide groove 311 can be one, two or more, such as more than two uniformly distributed along the circumferential direction. The first slider 212 matches the first slide groove 311, so that the first rotating shaft 21 and the first cam 31 are fixed in the circumferential direction, and the operation is more convenient. When the first cam 31 rotates and moves along the axial direction, the first slider 212 slides relatively along the first slide groove 311, so that the axial movement of the first cam 31 is more stable. At this time, the cam part of the first cam 31 interacts with the cam part of the second cam 32. It is necessary to apply an external force to the temple body 1 to make the first cam 31 rotate, which is more stable and reliable.

[0034] The first hole 211 passes through the first rotating shaft 21. The end of the first rotating shaft 21 away from the second cam 32 is also provided with a gap eliminating mechanism 5 that cooperates with the cam assembly 3. The cam assembly 3, the first rotating shaft 21 and the gap eliminating mechanism 5 are all located in the first mounting groove 41. Since there is a certain gap between the first slider 212 and the first slide groove 311, the gap eliminating mechanism 5 can eliminate the gap between the first slider 212 and the first slide groove 311, especially after the temple body 1 is opened relative to the frame, the first rotating shaft 21 and the first cam 31 are prevented from shaking relative to each other in the circumferential direction. The gap eliminating mechanism 5 can also ensure that the force is more uniform, and the movement is more stable and reliable. The clearance elimination mechanism 5 includes a third cam 51 and a fourth cam 52 that match each other. The third cam 51 and the fourth cam 52 are sequentially arranged along the axial direction of the rotating mechanism 2. The structures of the third cam 51 and the fourth cam 52 are substantially the same as those of the first cam 31 and the second cam 32. The third cam 51 is fixed in the first mounting groove 41, and the fourth cam 52 is located at an end of the first rotating shaft 21 away from the second cam 32. The third cam 51 is located in the first hole body 211, and a third cam that matches the second slide groove 511 on the third cam 51 is provided in the first hole body 211. The second slider 213 and the second slide groove 511 are arranged along the axial direction of the third cam 51. One end of the first elastic member 7 is pressed against the third cam 51 and the other end is pressed against the first cam 31. The second slider 213 and the second slide groove 511 usually correspond to each other one by one. The number and arrangement of the second slider 213 and the second slide groove 511 are determined according to the specific situation. The second slider 213 and the second slide groove 511 can be one, two or more, such as more than two uniformly distributed along the circumferential direction. The second slider 213 cooperates with the second slide groove 511 to fix the first shaft 21 and the third cam 51 in the circumferential direction, which is more convenient to operate. Figure 4 As shown, when the temple body 1 is opened relative to the frame, the first elastic member 7 interacts with the first cam 31 and the third cam 51 respectively, the first slide groove 311 on the first cam 31 cooperates with the first slider 212, and the second slider 213 cooperates with the second slide groove 511. At this time, the cam portion of the third cam 51 interacts with the cam portion of the fourth cam 52, so that the third cam 51 has a certain torque effect on the first shaft 21, and then can have a certain torque effect on the first cam 31, and the third cam 51 is also subjected to a corresponding reaction force, so that the gap between the first slider 212 and the first slide groove 311 and the gap between the second slider 213 and the second slide groove 511 can be eliminated, so as to prevent the first shaft 21 and the first cam 31 from shaking relative to each other in the circumferential direction and the first shaft 21 and the third cam 51 from shaking relative to each other in the circumferential direction, and the movement is more stable and reliable.

[0035] The second cam 32 is provided with a first stopper 321 matched with the first cam 31, and the first cam 31 is provided with a first limiting slide groove 313 matched with the first stopper 321 along its circumferential direction. The first stopper 321 matches with the first limiting slide groove 313, and the rotation of the first cam 31 can be limited and guided, which is more stable and reliable. Similarly, the fourth cam 52 is provided with a second stopper 521 matched with the third cam 51, and the third cam 51 is provided with a second limiting slide groove 513 matched with the second stopper 521 along its circumferential direction.

[0036] The cam portion of the fourth cam 52 is inserted into the first hole 211, and the cam portion of the second cam 32 is inserted into the first hole 211, so the structure is more compact and stable. The second cam 32 generally includes a chassis, and the cam portion of the second cam 32 is arranged on the chassis. The chassis can be against the end face of the first rotating shaft 21. A connecting plate connected to the base 4 can also be arranged on the chassis. The connecting plate and the base 4 can be connected by fasteners such as screws, or by welding, etc. The structure of the fourth cam 52 is basically the same as that of the second cam 32. The base 4 generally includes a detachably connected shell and a cover plate, and the shell and the cover plate can be connected by snap-fit ​​connection, etc. The shell and the cover plate are connected to form a first mounting groove 41, so that the base 4 is connected to the cam assembly 3, the first rotating shaft 21 and the gap elimination mechanism 5.

[0037] The first cam 31 is provided with a first groove 312 matched with one end of the first elastic member 7, and the third cam 51 is provided with a second groove 512 matched with the other end of the first elastic member 7, so that the structure is more compact and stable. The first elastic member 7 is usually a spring, which has a simple structure and is easy to operate. The first elastic member 7 can also be other suitable elastic blocks in the prior art.

[0038] The semi-automatic eyeglass leg mechanism also includes an FPC board 6, which is a flexible printed circuit board (Flexible Printed Circuit). It is a printed circuit board made of polyimide or polyester film as a substrate with high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, thin thickness, and good bendability. It can be connected to a corresponding power source through the FPC board 6, which is convenient for application in smart glasses, AR glasses, etc. Figure 6 , Figure 7 , Fig. 9As shown, the first rotating shaft 21 is provided with a first through hole 214 and a second through hole 215 for the FPC board 6 to pass through, and the first through hole 214 and the second through hole 215 are respectively connected with the first hole body 211, and the first connecting plate 22 is provided with a third groove body 221 for the FPC board 6 to pass through, and the first through hole 214 is close to the first connecting plate 22 and is connected with the third groove body 221, and the temple body 1 is provided with a second hole body 11 matched with the first connecting plate 22, and one end of the FPC board 6 is also located in the second hole body 11, and an avoidance interval matched with the FPC board 6 is also provided in the base 4, and the FPC board 6 is arranged through the second through hole 215, the first through hole 214, the third groove body 221 and the second hole body 11, so that the FPC board 6 is hidden inside the temple mechanism, and the safety, stability and reliability are higher.

[0039] Compared with the prior art, the advantages of the present invention are as follows: the two temple mechanisms are symmetrically mounted on both sides of the frame through the base 4, and when the temple body 1 is opened relative to the frame, an outward force is first applied to the temple body 1, and the temple body 1 rotates relative to the base 4 through the rotating mechanism 2, and the cam assembly 3 rotates synchronously with the rotating mechanism 2, and at the same time, the first elastic member 7 interacts with the cam assembly 3, so that the first elastic member 7 is compressed, and as the cam assembly 3 rotates to a specified position, such as when the temple body 1 rotates 30°, 45° or 60° relative to the base 4, at this time, there is no need to apply a force to the temple body 1 , but the first elastic member 7 elastically recovers and drives the cam assembly 3 to rotate, and the cam assembly 3 drives the rotating mechanism 2 to move synchronously, so that the temple body 1 is finally automatically opened. When the temple body 1 is closed relative to the frame, similarly, an inward force is first applied to the temple body 1. As the cam assembly 3 rotates to a specified position, the first elastic member 7 elastically recovers and drives the cam assembly 3 to rotate, so that the temple body 1 is finally automatically closed, thereby realizing semi-automatic opening and closing of the temple body 1, and after the two temple mechanisms are opened relative to the frame, the gap between the first slider 212 and the first slide groove 311 can be eliminated through the gap eliminating mechanism 5. The gap is formed to prevent the first rotating shaft 21 and the first cam 31 from shaking relative to each other in the circumferential direction, ensure that the force is more uniform, etc. The user can also apply an outward force to the two temple bodies 1, and the temple bodies 1 rotate outward through the rotating mechanism 2, and the cam assembly 3 rotates synchronously with the rotating mechanism 2. At the same time, the first elastic member 7 interacts with the cam assembly 3, so that the first elastic member 7 elastically exerts a reverse force on the temple body 1, so that the temple body 1 is elastically expanded outward relative to the base 4 and can automatically rebound and reset, such as elastically expanding outward by 5°, 10°, 15°, etc., which is convenient for different users to perform different adjustments. The spectacles can be adjusted according to the size of the face, the specific face shape, etc., and have a simple and compact structure, and are easy to operate and adjust. They are not prone to problems such as being too loose or too tight, unreliable, shaking, or sliding. They have high stability and reliability, and have better performance, comfort, and fit with the user, and can meet the needs of different users. They can also be connected to a corresponding power source through the FPC board 6, so that they are suitable for various glasses such as myopia glasses, goggles, swimming goggles, night vision goggles, e-sports glasses, sunglasses, smart glasses, AR glasses, etc., and have a wide range of applications, thereby expanding the application and development of the product.

It should be understood that, for those skilled in the art, without departing from the creative concept of the present disclosure, it is possible to make improvements or substitutions according to the above description, and all these improvements and substitutions should fall within the scope of protection of the claims attached to the present disclosure.
