[0034] In order to make the specific embodiment of the utility model or the technical scheme in the prior art more clearly, the drawings needed to be used in the specific embodiment or the prior art description will be simply introduced as follows. Obviously, the drawings in the following description are some embodiments of the utility model, and other drawings can be obtained by those skilled in the art without creative labor on the basis of these drawings.

[0035] The embodiments of the utility model will be described below in combination with Figs. 1 to 4 .

[0036] According to the embodiment of the utility model, on the one hand, a hinging structure is provided, comprising:

[0037] The first connecting piece 1 is connected with the second connecting piece 2 through the rotating piece 3.

[0038] The second connecting piece 2 is connected with the first connecting piece 1 through the rotating piece 3.

[0039] The rotating piece 3 is rotatably connected with the first connecting piece 1 and the second connecting piece 2 respectively.

[0040] The elastic limiting piece 4 is fixedly connected with the first connecting piece 1 at one end and extends to form an action part in a direction away from the first connecting piece 1 at the other end.

[0041] The limiting groove 5 is arranged on the second connecting piece 2 and is suitable for exerting an action force on the action part of the elastic limiting piece 4 in a direction opposite to the elastic deformation direction of the elastic limiting piece 4 when the first connecting piece 1 is rotated to a predetermined position relative to the second connecting piece 2.

[0042] It is easily understood that the spectacle frame and the temple are rotatably connected through the hinging structure. When folded, the temple is in contact with the frame and forms an angle of about 90°, so that the temple is relatively parallel to the frame and is in contact, which is convenient for storage and carrying. When in normal position, the first connecting piece 1 and the second connecting piece 2 form an angle of about 180°, so that the temple is relatively perpendicular to the frame and can be normally and comfortably worn. When in the predetermined position, the temple is extended relative to the normal position to form an angle greater than 180°, which relieves the pressure of the temple on the temple for users with large head circumference.

[0043] The hinging structure provided by the embodiment of the utility model realizes the rotatable connection between the first connecting piece 1 and the second connecting piece 2 through the rotating piece 3, so that the first connecting piece 1 and the second connecting piece 2 can rotate relative to each other. The elastic limiting piece 4 is fixedly connected with the first connecting piece 1 at one end and extends to form an action part. When the first connecting piece 1 is rotated relative to the second connecting piece 2, the elastic limiting piece 4 can be elastically deformed. The limiting groove 5 arranged on the second connecting piece 2 can exert an action force on the action part of the elastic limiting piece 4 in a direction opposite to the elastic deformation direction of the elastic limiting piece 4 when the first connecting piece 1 is rotated to a predetermined position. The problem of excessive stress on the components caused by excessive rotation angle is effectively avoided, and the situations such as weakening of the rebound effect of similar metal springs or breakage are prevented, thereby prolonging the service life of products such as glasses using the hinging structure, ensuring the stability and reliability of the structure during rotation, improving the user experience and reducing the maintenance cost.

[0044] Further, the predetermined position is a position where the first connecting piece 1 is rotated beyond the position in line with the second connecting piece 2.

[0045] It should be noted that the rotation of the first connecting piece 1 to a position beyond the co-line of the second connecting piece 2 is the predetermined position. At this position, the limiting groove 5 interacts with the action part of the elastic limiting piece 4, so that the elastic deformation of the elastic limiting piece 4 due to the rotation of the first connecting piece 1 is constrained by the reverse force. This constraint can effectively control the further rotation amplitude of the first connecting piece 1, prevent it from bearing excessive stress due to excessive rotation of the rotating piece 3 or other related components. In the application scenario of glasses, it can avoid excessive opening of the glasses legs, prevent the metal spring from failing due to excessive force on the glasses leg and frame connection structure, ensure the stability and durability of the overall structure of the glasses, keep the glasses in good performance for a long time, and reduce the inconvenience and maintenance cost caused by structural damage.

[0046] Further, the elastic limiting piece 4 is arranged on the side surface tangent to the circumferential surface of the rotating piece 3, and the limiting groove 5 is arranged on the side surface tangent to the circumferential surface of the rotating piece 3 and is an inwardly recessed strip-shaped groove.

[0047] It is easy to understand that the arrangement of the elastic limiting piece 4 and the limiting groove 5 on the side surface tangent to the circumferential surface of the rotating piece 3 makes the structure compact and reasonable. During rotation, the elastic limiting piece 4 can deform in time, and when it reaches the predetermined position, the strip-shaped limiting groove 5 limits the rotation by force, effectively preventing component damage due to excessive rotation, improving the stability and durability of the hinge structure, ensuring the reliable operation of the glasses during long-term use, reducing the maintenance frequency, and prolonging the service life.

[0048] In an alternative embodiment, the limiting groove 5 can be an arc-shaped groove, which can form a smoother transition contact with the action part of the elastic limiting piece 4, optimizing the stress distribution.

[0049] Further, it further comprises:

[0050] The positioning piece 6 is arranged at the end of the action part away from the first connecting piece 1 and is arranged towards the limiting groove 5. The positioning piece 6 is adapted to be clamped in the limiting groove 5 when the first connecting piece 1 rotates to the predetermined position relative to the second connecting piece 2.

[0051] It should be noted that the added positioning piece 6 further improves the rotation control mechanism in structure. When the first connecting piece 1 rotates to the predetermined position, the positioning piece 6 arranged at the action part can be accurately clamped in the limiting groove 5, enhancing the accuracy and reliability of the rotation angle limitation, effectively avoiding the rotation beyond the position caused by external factors, so that the entire hinge structure can maintain high stability, thereby ensuring the safety and durability of the product using the structure during operation, and reducing the risk of failure caused by structural instability. Since the groove body of the limiting groove 5 is lower than the circumferential surface of the rotating piece 3, in order to ensure the accurate application of the reverse force, an outwardly protruding positioning piece is arranged at the end of the elastic limiting piece 4.

[0052] In an optional embodiment, the positioning member 6 can adopt a magnetic attraction structure, and the magnetic attraction force is used to realize the clamping with the limiting groove 5. In this way, the stability of the positioning can be ensured, and mechanical wear can be reduced. Or the positioning member 6 is designed in the form of an elastic clamping hook, and the positioning member 6 is clamped into the limiting groove 5 through elastic deformation. In this way, the clamping effect can be ensured, the processing difficulty and cost can be reduced, and the service life of the hinge structure can be prolonged.

[0053] Further, a buffer pad can be arranged in the limiting groove 5, and the material of the buffer pad is silica gel. When the positioning member 6 is clamped, the buffer pad can play a buffering role, reduce the damage caused by the collision impact to the structure, and prolong the service life of the hinge structure.

[0054] Further, the positioning member 6 is a spherical protrusion.

[0055] As can be easily understood, the positioning member 6 is a spherical protrusion. When the positioning member 6 is clamped with the limiting groove 5, the contact area is small and the stress distribution is uniform, the wear and jamming are reduced, the clamping is smooth and accurate when rotating to the predetermined position, the stability and reliability of the hinge structure are improved, the rotation angle is accurately controlled, the service life of the device is prolonged, the maintenance cost and use risk caused by the failure of the positioning member are reduced.

[0056] In an optional embodiment, the positioning member 6 can be replaced by a conical protrusion, the tip of the conical protrusion faces the limiting groove 5, and the positioning member 6 can be accurately guided into the limiting groove 5 when clamped, thereby reducing the processing precision requirement of the limiting groove 5. Or the positioning member 6 adopts a hemispherical structure made of elastic rubber material. The rubber has elastic buffering characteristics. When clamped, the impact is reduced, the clamping effect is good even if there is a slight misalignment, the adaptability of the structure to complex working conditions is improved, and the stable operation of the hinge structure is ensured.

[0057] Further, the elastic limiting member 4 is a metal alloy elastic limiting member.

[0058] As can be easily understood, the elastic limiting member 4 is made of metal alloy material. When the first connecting member 1 and the second connecting member 2 are repeatedly rotated, the elastic limiting member 4 can stably deform and recover, effectively limit and adjust the rotation angle. The higher strength can withstand greater stress and is not easy to permanently deform or be damaged, thereby ensuring the reliability and durability of the hinge structure in long-term and complex stress environments.

[0059] Further, the metal alloy elastic limiting member is a titanium alloy elastic limiting member.

[0060] It should be noted that the titanium alloy material is used as the elastic limiting member 4. The titanium alloy has a lighter quality, which can reduce the overall weight while ensuring the structural strength, thereby facilitating the lightweight design of the product. In addition, the titanium alloy has good corrosion resistance, so that the elastic limiting member 4 can stably work in various harsh environments, effectively resist the erosion of factors such as oxidation and humidity, and prolong the service life.

[0061] Further, the elastic limiting member 4 and the first connecting member 1 are integrally formed.

[0062] It is easy to understand that the elastic limiting member 4 and the first connecting member 1 are integrally formed to enhance the overall integrity and stability. Under the action of external force, the stress is uniformly distributed, reducing the risk of local stress concentration and component damage. Avoiding the loosening and separation of the connecting components, ensuring the stable function of the elastic limiting member 4, protecting the long-term reliable operation of the hinged structure, improving the durability and safety. Reduce the number of parts and assembly processes during production and manufacturing, improve production efficiency and reduce cost.

[0063] In other optional embodiments, the elastic limiting member 4 and the first connecting member 1 can also be firmly connected by welding, but the appropriate welding process needs to be selected to ensure the welding strength and precision, meet the structural performance requirements. Or use riveting process, use high-strength rivets to connect, ensure the reliability of connection while facilitating later maintenance and repair.

[0064] Further, the rotating member 3 is a rotating shaft.

[0065] It is easy to understand that the rotating member 3 is a rotating shaft, which makes the first connecting member 1 and the second connecting member 2 rotate smoothly and stably. The rotating shaft cooperates with the elastic limiting member 4 and the limiting groove 5 to flexibly adjust the angle according to the elastic deformation, and the limiting amplitude is precisely limited by the limiting groove 5, which ensures the reliable and safe operation. Good durability, low wear rate during long-term use, prolong the service life of the hinged structure.

[0066] In an optional embodiment, a ball bearing structure can also be used as the rotating member 3, which uses balls to reduce frictional resistance and improve rotating flexibility and efficiency, which is obvious in scenarios with high requirements for rotating speed and smoothness.

[0067] According to the embodiments of the utility model, on the other hand, an eyeglasses is also provided, which comprises:

[0068] The frame;

[0069] Two temples;

[0070] Two above-mentioned hinged structures, two temples are connected with the frame through a hinged structure respectively, and the frame is connected with the second connecting member 2, and the temple is connected with the first connecting member 1.

[0071] Need to explain, the hinge structure plays a key role in the connection and adjustment in glasses. Through the connection of the glasses legs and the first connecting piece 1, the connection of the glasses frame and the second connecting piece 2, the flexible rotation of the glasses legs relative to the glasses frame is realized. In the wearing process, the user can easily adjust the opening angle of the glasses legs according to the head shape and comfort requirements, and the cooperation of the elastic limiting piece 4 and the limiting groove 5 effectively prevents the glasses legs from being excessively opened, ensures the stability and reliability of the glasses in use, avoids the glasses from falling off or wearing uncomfortable due to the abnormal angle of the glasses legs. In the face of the needs of users with different head circumferences, the existence of the elastic limiting piece 4 and the limiting groove 5 makes the glasses legs be able to adaptively adjust the angle within a certain range. For users with larger head circumference, the glasses legs can be appropriately opened outward to reduce the pressure on the temple; for users with smaller head circumference, the glasses legs can also closely fit the head contour, ensure the comfort and stability of the glasses wearing, and improve the universality and user satisfaction of the glasses products.
