Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1 to 11, as an embodiment of the present utility model, the present utility model includes two symmetrical mirror frames 1, wherein the two symmetrical mirror frames 1 are connected in a folding manner, a main mirror leg 2 is disposed on the mirror frame 1, and the mirror frame 1 is connected with the main mirror leg 2 in a folding manner through an elastic rotation mechanism;
When the main glasses leg 2 is folded to be close to the glasses frame 1 along the rotation axis of the elastic rotation mechanism and passes over the balance position, the elastic rotation mechanism can automatically assist the main glasses leg 2 to be folded to be close to the glasses frame 1 until the main glasses leg and the glasses frame 1 are attached in parallel;
When the main glasses leg 2 is unfolded outwards from being parallel to the glasses frame 1 along the rotating axis of the elastic rotating mechanism and passes over the balance position, the elastic rotating mechanism can automatically assist the main glasses leg 2 to be unfolded until the main glasses leg 2 is perpendicular to the glasses frame 1.
In this embodiment, when the main temple 2 is folded from the frame 1 to be unfolded outwards to be perpendicular, the method can be divided into three stages, wherein the first stage firstly makes the main temple 2 unfolded to the equilibrium position along the rotation center of the elastic rotation mechanism by giving an external force to the main temple 2 (the external force is larger than the resistance of the elastic rotation mechanism to the unfolding of the main temple 2), the second stage makes the main temple 2 unfolded to be at the equilibrium position with the frame 1 (the main temple 2 is in the equilibrium state under the condition of not receiving the external force), and the third stage makes the main temple 2 unfolded to be perpendicular to the frame 1 when the main temple 2 is unfolded beyond the equilibrium position (the external force is not needed in the process, the force given to the main temple 2 by the elastic rotation mechanism is enough to drive the main temple 2 to be unfolded). Then, the two eyeglass frames 1 are unfolded from the folded and attached state (the included angle is 0 °) to the parallel state (the included angle is 180 °).
When the main temple 2 is folded inwards from a state perpendicular to the frame 1 to a state of being fully parallel to the frame 1, the process still comprises three stages, namely, the first stage firstly folds the main temple 2 to a balance position by giving an external force to the main temple 2 (the external force is larger than the resistance of the elastic rotating mechanism for unfolding the main temple 2), the second stage of the main temple 2 and the frame 1 are at the balance position (the main temple 2 is in the balance state under the condition of not being subjected to the external force at the moment), and the third stage of folding the main temple 2 beyond the balance position to be parallel to the frame 1 (the process does not need the external force, and the force given to the main temple 2 by the elastic rotating mechanism is enough to drive the main temple 2 to fold). Then, the two lens frames 1 are folded from a parallel state (the included angle is 180 degrees) to a folded and attached state (the included angle is 0 degrees).
Because the elastic rotating mechanism can not rotate independently under the condition of no external interference, the folding or unfolding state of the glasses can be always limited after folding or unfolding, and the folding and unfolding stability of the glasses legs is improved.
As a further scheme of the utility model, the two mirror frames 1 are mutually connected in a folding way through a first hinge 9, the first hinge 9 comprises two hinged arc rods 901, and the two hinged arc rods 901 are mutually hinged and respectively and fixedly arranged on the two mirror frames 1.
In this embodiment, the hinge point of the two hinge arc rods 901 is the folding center of the first hinge 9, that is, the folding center of the two frames 1 when folded or unfolded. The mirror frame 1 is folded or unfolded along the rotation center under the pushing of external force.
As a further scheme of the utility model, the elastic rotation mechanism comprises a first connecting groove 101 arranged on the mirror frame 1, a first connecting plate 3 is fixedly arranged on the first connecting groove 101, and a first spring column 301 is fixedly arranged on the first connecting plate 3;
The main glasses leg 2 is provided with a second connecting groove 201, a second connecting plate 4 is fixedly arranged in the second connecting groove 201, a second spring column 401 is fixedly arranged on the second connecting plate 4, and the first spring column 301 and the second spring column 401 are connected through a spring 6;
One end of the connecting rod 5 is fixedly mounted on the second connecting plate 4, one end of the connecting rod, which is far away from the second connecting plate 4, is rotatably mounted on the first connecting plate 3, and a rotation connecting point is located between the first spring post 301 and the second spring post 401.
In this embodiment, the tension of the spring 6 is transferred to the first connecting plate 3 and the second connecting plate 4 through the first spring post 301 and the second spring post 401, and the connection line between the first spring post 301 and the second spring post 401 is the direction of the elastic force of the spring 6. The connecting rod 5 is rotationally connected with the first connecting plate 3, and the connection part is the rotation center of the first connecting plate 3 and the second connecting plate 4, namely the rotation center of the elastic rotation mechanism.
The direction of the elastic force of the spring 6 is changed with the position of the first spring post 301 during the complete folding or complete unfolding between the main temple 2 and the frame 1. When the rotation center of the elastic rotation mechanism is on the same line with the first spring post 301 and the second spring post 401, the elastic force of the spring 6 is maximum, the direction passes through the rotation center of the elastic rotation mechanism along the line, and the main glasses leg 2 is in a stress balance state, so that the spring 6 cannot drive the elastic rotation mechanism to rotate, and the position is the balance position. When the first spring post 301 passes over the balance position, the elastic force of the spring 6 does not pass through the rotation center, and at this time, the elastic force of the spring 6 acts on the first spring post 301 and is divided into a tangential force driving the first spring post 301 to rotate around the rotation center, so that the first spring post 301 rotates to enable the main temple 2 and the glasses frame 1 to rotate relatively.
When the glasses are in a fully folded and attached state, the elastic direction of the springs 6 does not pass through the rotation center, the springs 6 are in a stretched state, and under the action of elastic force, the glasses are always in the state. When the glasses are required to be used, an external force is required to be provided to the glasses against the elastic force of the springs 6 to rotate the first spring post 301 to the equilibrium position. When the first spring post 301 passes over the equilibrium position, the first spring post 301 will rotate under the force of the spring 6 (no external force is required to assist in this process) until the main temple 2 and the frame 1 are fully extended.
On the contrary, when the glasses need to be folded, the first spring post 301 needs to be made to pass through the balance position with the help of external force, and then the first spring post 301 rotates under the action of the elastic force of the spring 6, so that the main glasses leg 2 and the glasses frame 1 are folded and attached in parallel.
As a still further scheme of the utility model, one end of the main glasses leg 2 far away from the glasses frame 1 is provided with a secondary glasses leg 7, and the main glasses leg 2 and the secondary glasses leg 7 are connected through a folding mechanism;
The folding mechanism comprises a third connecting groove 202 formed in one end, far away from the second connecting groove 201, of the main glasses leg 2 and a fourth connecting groove 701 formed in the auxiliary glasses leg 7, hinge plates 8 are fixedly arranged on the third connecting groove 202 and the fourth connecting groove 701 respectively, and the two hinge plates 8 are hinged to each other and arranged in the third connecting groove 202 and the fourth connecting groove 701.
In this embodiment, folding or unfolding between the primary temple 2 and the secondary temple 7 can be achieved by folding or unfolding two hinge plates 8. The hinge joint of the two hinge plates 8 is the folding center of the two hinge plates 8, namely the folding center of the main glasses leg 2 and the auxiliary glasses leg 7.
When the glasses are used, the main glasses leg 2 and the auxiliary glasses leg 7 are unfolded to form a glasses leg with complete functions, and the glasses leg is folded during storage, so that the storage space is reduced, and the exposed glasses leg is prevented from being bent and damaged during storage.
As a still further scheme of the present utility model, a step is disposed on a surface of the hinge portion of the hinge arc rod 901, which is close to the arc center, and the two steps are mutually abutted when an included angle between the two mirror frames 1 is 180 °.
In this embodiment, the articulated arc bars 901 feature steps that limit the maximum included angle (180 °) between the frames 1. In use, the two relatively parallel frames 1 more closely conform to the physiological characteristics of the human eye.
As a still further proposal of the utility model, a nose pad 10 is fixedly arranged on the mirror frame 1, one side of the nose pad 10 far away from the mirror frame 1 is arc-shaped, and one end of the auxiliary mirror leg 7 far away from the main mirror leg 2 is half arc-shaped which is bent downwards.
In this embodiment, when wearing glasses, the nose pad 10 contacts with the bridge of the nose of the person, provides supporting force for the glasses, and the arc design more fits the appearance characteristic of the nose of the person, makes the nose pad 10 and the bridge of the nose difficult to separate, has more supporting conditions.
When wearing glasses, auxiliary glasses leg 7 and human ear direct contact, auxiliary glasses leg 7 have half arc form characteristic and make auxiliary glasses leg 7 and human ear be difficult to separate, increase the stability of wearing glasses.
As still another aspect of the present utility model, the frame 1 is curved with an arc, and the frame 1 is made of a rigid material.
In this embodiment, the frame 1 provides room for the mounting of lenses for a curved design. The radian of each face is different, so that the mirror frame 1 is more fit with the physiological appearance of the human eyes, and the visual angle of a person is not limited under the condition of not increasing the area of the mirror frame 1.
The above-described embodiments are illustrative, not restrictive, and the technical solutions that can be implemented in other specific forms without departing from the spirit or essential characteristics of the present utility model are included in the present utility model.
