[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0042] See also Figure 1 to Figure 11 As an embodiment of the utility model, it comprises two symmetrically arranged eyeglass frames 1, and the two symmetrical eyeglass frames 1 are foldably connected, the eyeglass frames 1 are provided with main eyeglass legs 2, and the eyeglass frames 1 and the main eyeglass legs 2 are foldably connected via an elastic rotating mechanism;

[0043] When the main temple 2 is folded toward the frame 1 along the rotation axis of the elastic rotation mechanism and passes the equilibrium position, the elastic rotation mechanism can automatically assist the main temple 2 to be folded toward the frame 1 until the two are parallel and attached;

[0044] When the main temple 2 is unfolded outwardly along the rotation axis of the elastic rotation mechanism from being parallel to the frame 1 and passing the equilibrium position, the elastic rotation mechanism can automatically assist the main temple 2 to unfold until the main temple 2 is perpendicular to the frame 1.

[0045] In this embodiment, when the main mirror leg 2 is folded with the frame 1 and unfolded outward to be perpendicular, it can be divided into three stages: in the first stage, an external force is applied to the main mirror leg 2 to make it unfold to a balanced position along the rotation center of the elastic rotating mechanism (the external force is greater than the resistance of the elastic rotating mechanism to the unfolding of the main mirror leg 2); in the second stage, the main mirror leg 2 is unfolded to a balanced position between the frame 1 (at this time, the main mirror leg 2 is in a balanced state without being subjected to external force); in the third stage, the main mirror leg 2 is unfolded beyond the balanced position to be perpendicular to the frame 1 (this process does not require external force, and the force applied to the main mirror leg 2 by the elastic rotating mechanism is sufficient to drive the main mirror leg 2 to unfold). Then, the two frames 1 are unfolded from the folded and fitted state (the angle is 0°) to the parallel state (the angle is 180°).

[0046] When the main mirror leg 2 is folded inward from a perpendicular state to the frame 1 to a completely parallel and fitted state, the process is still divided into three stages: the first stage is to fold the main mirror leg 2 to a balanced position by applying an external force (the external force is greater than the resistance of the elastic rotating mechanism to the main mirror leg 2); the second stage is when the main mirror leg 2 and the frame 1 are in a balanced position (at this time, the main mirror leg 2 is in a balanced state without being subjected to external force); the third stage is when the main mirror leg 2 is folded past the balanced position to parallel and fit with the frame 1 (this process does not require external force, and the force applied to the main mirror leg 2 by the elastic rotating mechanism is sufficient to drive the main mirror leg 2 to fold). Then, the two frames 1 are folded from a parallel state (angle of 180°) to a folded and fitted state (angle of 0°).

[0047] Since the elastic rotating mechanism will not rotate autonomously without external interference, it will always limit the folding or unfolding state of the glasses after folding or unfolding, thereby increasing the stability of the folding and unfolding of the temples.

[0048] As a further solution of the utility model, the two frames 1 are foldably connected to each other via a first hinge 9, wherein the first hinge 9 comprises two hinged arc rods 901, and the two hinged arc rods 901 are hinged to each other and fixedly mounted on the two frames 1 respectively.

[0049] In this embodiment, the hinge point of the two hinged arc rods 901 is the folding center of the first hinge 9, that is, the folding center of the two mirror frames 1. The mirror frames 1 are folded or unfolded along this rotation center under the push of external force.

[0050] As a further solution of the utility model, the elastic rotation mechanism includes a first connecting groove 101 provided on the lens frame 1, a first connecting plate 3 is fixedly mounted on the first connecting groove 101, and a first spring column 301 is fixedly mounted on the first connecting plate 3;

[0051] The main temple 2 is provided with a second connection groove 201, in which a second connection plate 4 is fixedly installed; the second connection plate 4 is fixedly installed with a second spring column 401; the first spring column 301 and the second spring column 401 are connected via a spring 6;

[0052] One end of the connecting rod 5 is fixedly mounted on the second connecting plate 4 , and one end thereof away from the second connecting plate 4 is rotatably mounted on the first connecting plate 3 , and the rotation connection point is located between the first spring column 301 and the second spring column 401 .

[0053] In this embodiment, the tension of the spring 6 is transmitted to the first connecting plate 3 and the second connecting plate 4 through the first spring column 301 and the second spring column 401, and the line connecting the first spring column 301 and the second spring column 401 is the direction of the elastic force of the spring 6. The connecting rod 5 and the first connecting plate 3 are rotationally connected, and this connection position is the rotation center of the first connecting plate 3 and the second connecting plate 4, that is, the rotation center of the elastic rotation mechanism.

[0054] During the process of the main mirror leg 2 and the mirror frame 1 being completely folded or fully unfolded, the direction of the elastic force of the spring 6 changes with the position of the first spring column 301. When the rotation center of the elastic rotating mechanism is on the same straight line as the first spring column 301 and the second spring column 401, the elastic force of the spring 6 is the largest, and the direction passes through the rotation center of the elastic rotating mechanism along this straight line. The main mirror leg 2 is in a force balance state, so the spring 6 cannot drive the elastic rotating mechanism to rotate, and this position is the equilibrium position. When the first spring column 301 passes the equilibrium position, the elastic force of the spring 6 does not pass through the rotation center. At this time, the elastic force of the spring 6 acting on the first spring column 301 will be divided into a tangential force that drives the first spring column 301 to rotate around the rotation center, so that the first spring column 301 rotates to make the main mirror leg 2 and the mirror frame 1 rotate relative to each other.

[0055] When the glasses are in a completely folded and fitted state, the direction of the elastic force of the spring 6 does not pass through the rotation center, and the spring 6 is in a stretched state. Under the action of the elastic force, the glasses will always be in this state. When the glasses need to be used, an external force is required to overcome the elastic force of the spring 6, so that the first spring column 301 rotates to a balanced position. When the first spring column 301 passes the balanced position, the first spring column 301 will rotate under the elastic force of the spring 6 (no external force is required at this time) until the main temple 2 and the frame 1 are fully unfolded.

[0056] On the contrary, when the glasses need to be folded, the first spring column 301 needs to pass the equilibrium position with the help of external force, and then the first spring column 301 will rotate under the elastic force of the spring 6 to make the main temple 2 fold and fit parallel to the frame 1.

[0057] As a further solution of the utility model, a secondary temple 7 is provided at one end of the main temple 2 away from the mirror frame 1, and the main temple 2 and the secondary temple 7 are connected by a folding mechanism;

[0058] The folding mechanism includes a third connecting groove 202 opened on the end of the main temple 2 away from the second connecting groove 201 and a fourth connecting groove 701 opened on the auxiliary temple 7, and hinge plates 8 are respectively fixedly installed on the third connecting groove 202 and the fourth connecting groove 701, and the two hinge plates 8 are hingedly installed in the third connecting groove 202 and the fourth connecting groove 701.

[0059] In this embodiment, the main temple 2 and the auxiliary temple 7 can be folded or unfolded by folding or unfolding the two hinge plates 8. The hinge point of the two hinge plates 8 is the folding center of the two hinge plates 8, that is, the folding center of the main temple 2 and the auxiliary temple 7.

[0060] When using the glasses, the main temple 2 and the auxiliary temple 7 are unfolded to form a temple with complete functions; when storing, they are folded up, which reduces the storage space and avoids the exposed temple from being bent and damaged during storage.

[0061] As a further solution of the present invention, a step is provided on a surface of the hinged portion of the hinged arc rod 901 close to the arc center, and the two steps conflict with each other when the angle between the two frames 1 is 180°.

[0062] In this embodiment, the hinged arc rod 901 has a step feature, which limits the maximum angle (180°) between the frames 1. When in use, the two relatively parallel frames 1 are more in line with the physiological characteristics of human eyes.

[0063] As a further solution of the utility model, a nose pad 10 is fixedly mounted on the frame 1; the side of the nose pad 10 away from the frame 1 is arc-shaped; the end of the secondary temple 7 away from the main temple 2 is semi-arc-shaped and bent downward.

[0064] In this embodiment, when wearing glasses, the nose pad 10 contacts the bridge of the nose to provide support for the glasses. The arc-shaped design fits the appearance of the human nose better, making it difficult for the nose pad 10 to separate from the bridge of the nose, providing better support conditions.

[0065] When the glasses are worn, the auxiliary temple 7 is in direct contact with the human ear. The semi-arc shape of the auxiliary temple 7 makes it difficult for the auxiliary temple 7 to separate from the human ear, thereby increasing the stability of wearing the glasses.

[0066] As a further solution of the present invention, the frame 1 is in a curved shape with an arc, and the frame 1 is made of a rigid material.

[0067] In this embodiment, the frame 1 is designed in a curved surface to provide space for the installation of lenses. The different curvatures of each surface allow the frame 1 to better fit the physiological appearance of the human eye, and the human visual angle is not restricted without increasing the area of ​​the frame 1.

[0068] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
