Description

Amorphous metal elastic hinge component for glasses and glasses

[0001] This application is based on the Chinese utility model application with application number 202420341755.7 filed on February 23, 2024, entitled “A kind of amorphous metal elastic hinge component for glasses and glasses”, and claims its priority. Technical Field

[0002] The present application relates to the technical field of glasses, and in particular to an amorphous metal elastic hinge component for glasses and glasses. Background Art

[0003] The hinge of glasses is used to connect the legs of the glasses to the frames. The legs of the glasses frames that people usually use are strip-shaped, and the legs and frames are connected by a hinge structure. When the glasses are used, the legs are fully opened, placed on the ears, and clamped on both sides of the face to fix the glasses rims. Long-term opening and closing operations will cause the hinge position or the legs of the glasses to deform, causing the frames to be unbalanced and affecting the user's vision.

[0004] Existing improvements to the hinge structure, as shown in Chinese patent 202221615601.X, are made by arranging a spring sheet at the hinge structure position to enable it to adaptively deform, thereby improving the comfort and deformation resistance of glasses. However, in order to ensure that the spring sheet has good elasticity, it needs to be set to a lower thickness. However, this setting brings another problem, that is, when an external force bends the temple of the glasses, the spring sheet is in the direct tensile force position, and the thinner thickness of the spring sheet will cause the bending resistance of the hinge structure to decrease. When the external force reaches a certain level, it will cause irreversible deformation or breakage of the hinge structure. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved.

[0026] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0028] In the description of this application, it should be noted that, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood by those skilled in the art in specific circumstances.

[0029] As shown in Figures 1-6, in one embodiment, the present application provides, on the one hand, an amorphous metal elastic hinge component for glasses, which is used to connect the legs of glasses and the frames of glasses, including an amorphous metal spring 1, a first connecting part 2 and a second connecting part 3, one of the first connecting part 2 and the second connecting part 3 is used to connect to the frames of glasses, and the other of the first connecting part 2 and the second connecting part 3 is used to connect to the legs of glasses; the first connecting part 2 and the second connecting part 3 are hinged to form a hinge structure 4; the amorphous metal spring 1 is arranged around the hinge structure 4, one end of the amorphous metal spring 1 is connected to the first connecting part 2, and the other end of the amorphous metal spring 1 is a free end and a gap is left between the hinge structure; when the legs of glasses are unfolded to approximately 90°, the other end of the amorphous metal spring 1 abuts the second connecting part 3 to provide elasticity for the legs of glasses to further expand outward; when the legs of glasses are further expanded outward from approximately 90°, the gap between the other end of the amorphous metal spring 1 and the hinge structure gradually shrinks until the other end of the amorphous metal spring 1 abuts the hinge structure, or until the first connecting part 2 abuts the second connecting part 3.

[0030] According to the amorphous metal elastic hinge component for glasses provided by the present application, an amorphous metal spring 1 is used for the elastic hinge component for glasses, which is used as a connecting structure between the glasses frame and the glasses legs. The amorphous metal elastic hinge component for glasses of the present application is set. On the one hand, compared with other existing elastic hinge structures 4, the design of the amorphous metal spring 1 surrounding the hinge structure 4 is adopted, so that the hinge structure 4 and the amorphous metal spring 1 form an integrated structure, ensuring that the amorphous metal spring 1 has a sufficiently long elastic section, which can improve the wearer's comfort and avoid the clamping effect of the glasses legs. At the same time, the internal space of the amorphous metal spring 1 is also filled by the hinge structure 4, so that the space is fully utilized, the volume of the elastic hinge component is reduced, and the elastic hinge is avoided. The excessive size of the component causes problems with aesthetics or wearing comfort. When the glasses leg is impacted or used improperly (such as violently bent) and expands further outward from approximately 90°, the gap between the other end of the amorphous metal shrapnel 1 and the hinge structure gradually shrinks until the other end of the amorphous metal shrapnel 1 abuts against the hinge structure, or until the first connection part 2 abuts against the second connection part 3, thereby realizing direct force conduction between the hinge structure and the second connection part 3 or realizing direct force conduction between the first connection part 2 and the second connection part 3, avoiding the amorphous metal shrapnel 1 from breaking as a direct tensile force point; the setting of the hinge structure 4 can reduce the external force on the amorphous metal shrapnel 1, and improve the resistance of the amorphous metal shrapnel 1 to external force breakage.

[0031] In one embodiment, the amorphous metal shrapnel 1 is selected from one of a zirconium-based amorphous alloy shrapnel, a copper-based amorphous alloy shrapnel, an iron-based amorphous alloy shrapnel, a magnesium-based amorphous alloy shrapnel, and a titanium-based amorphous alloy shrapnel.

[0032] In a preferred embodiment, the amorphous metal spring 1 is selected from zirconium-based amorphous alloys.

[0033] Zirconium-based amorphous alloys have high material strength, with a tensile strength of 800 to 1500 MPa, which is 2.5 times that of 316 stainless steel and 1.5 times that of titanium alloy. The hinge structure 4 can be designed to be lighter and thinner, reducing the weight of the accessory and improving the wearer's comfort. At the same time, the high strength of the material ensures that the glasses will not deform during long-term use, thereby improving the quality of the glasses. The Vickers hardness of zirconium-based amorphous alloys is 440 to 540 Hv, far exceeding that of stainless steel and titanium alloys, and it has less wear during use. It will not deform or lose elasticity even in long-term use. The elastic deformation rate of zirconium-based amorphous alloy materials is 0.6 to 1.5%, which is 6 times higher than that of 316 stainless steel, with better elasticity and better wearing comfort.

[0034] As shown in Figures 1-6, in one embodiment, the hinge structure 4 includes a first hinge portion 41 and a second hinge portion 42, the first hinge portion 41 is connected to one of the first connection portion 2 and the second connection portion 3, and the second hinge portion 42 is connected to the other of the first connection portion 2 and the second connection portion 3.

[0035] The first hinge portion 41 and the second hinge portion 42 are hinged to form a hinge structure 4. On the one hand, compared with other existing elastic hinge structures 4, the hinge structure 4 is arranged inside the amorphous metal dome 1, so that the hinge structure 4 and the amorphous metal dome 1 form an integrated structure, ensuring that the amorphous metal dome 1 has a sufficiently long elastic section, which can improve the wearer's comfort and avoid the clamping effect of the glasses leg. At the same time, the internal space of the amorphous metal dome 1 is also filled by the hinge structure 4, realizing full utilization of the space, reducing the volume of the elastic hinge component, and avoiding the problem of aesthetics or wearing comfort caused by the excessive volume of the elastic hinge component;

[0036] Furthermore, when the legs of the glasses are impacted or used improperly (such as being violently bent) and further expand outward from approximately 90°, the gap between the other end of the amorphous metal shrapnel 1 and the hinge structure gradually shrinks until the other end of the amorphous metal shrapnel 1 abuts against the hinge structure, thereby realizing direct force transmission between the hinge structure and the second connecting part 3, thereby preventing the amorphous metal shrapnel 1 from breaking as a direct tensile force point; the setting of the hinge structure 4 can reduce the external force on the amorphous metal shrapnel 1, and improve the resistance of the amorphous metal shrapnel 1 to external force breakage.

[0037] As shown in FIG. 1-6 , in one embodiment, there are two second hinged portions 42 and one first hinged portion 41 , and the two second hinged portions 42 are disposed on both sides of the first hinged portion 41 .

[0038] Through the above-mentioned structural setting, the first hinge part 41 and the second hinge part 42 are arranged to rotate relative to each other, so that the first hinge part 41 is the actual friction part in the hinge structure 4. In the process of the expansion angle of the glasses leg further expanding from approximately 90°, the gap between the other end of the amorphous metal spring 1 and the hinge structure gradually decreases until the other end of the amorphous metal spring 1 abuts against the hinge structure, so that direct force transmission is achieved between the hinge structure and the second connection part 3, avoiding the amorphous metal spring 1 from breaking as a direct tensile force point; the setting of the hinge structure 4 can reduce the external force on the amorphous metal spring 1, improve the resistance of the amorphous metal spring 1 to external force breakage, and ensure the long-term use of the amorphous metal elastic hinge component for glasses.

[0039] As shown in Figures 1-6, in one embodiment, the first hinge part 41 and the second hinge part 42 are both annular, and the first hinge part 41 and the second hinge part 42 are coaxially arranged. A hinge screw 43 is arranged to pass through the first hinge part 41 and the second hinge parts 42 located on both sides of the first hinge part 41 to form a hinge structure 4, and the hinge screw 43 is fixed on the two second hinge parts 42, and the first hinge part 41 and the hinge screw 43 rotate relative to each other.

[0040] The second hinge part 42 is arranged at the end of the second connecting part 3, and the first end of the first connecting part 2 extends to the position of the second hinge part 42 and is connected to the first hinge part 41. A hinge screw 43 is arranged to pass through the first hinge part 41 and the second hinge part 42 located on both sides of the first hinge part 41 to form a hinge structure 4, so that the first hinge part 41, the second hinge part 42 and the hinge screw 43 are arranged to rotate relative to each other. Since the first hinge part 41 and the second hinge part 42 are both located at the center of the circle, the support part and the amorphous metal spring 1 are subjected to balanced force, thereby extending the service life of the elastic hinge parts.

[0041] As shown in FIG. 3-6 , in one embodiment, the amorphous metal spring 1 is arc-shaped, and a first hinge portion 41 is provided at one end of the amorphous metal spring 1 .

[0042] Specifically, the amorphous metal spring 1 is arc-shaped, and its arc angle is greater than or equal to 90°.

[0043] Amorphous metal itself has high elasticity. The arc-shaped structure is conducive to further improving the elasticity of the amorphous metal spring 1, so that it can withstand greater forces without plastic deformation.

[0044] In a preferred embodiment, the curvature of the amorphous metal dome 1 is 180°-360°. Specifically, the curvature of the amorphous metal dome 1 is any point value among 90°, 180°, 270° or 360° or a range consisting of any two point values.

[0045] Setting the amorphous metal spring 1 as an arc-shaped sheet structure is beneficial to the transmission of the torque it is subjected to and improves its elastic performance.

[0046] Specifically, the amorphous metal shrapnel 1 of the present application is arranged around the hinge structure 4 to form an integrated structure. On the one hand, it reduces the volume of the elastic hinge component and can effectively reduce material costs, thereby improving the comfort of the wearer and avoiding the clamping effect of the glasses leg. At the same time, compared with other existing elastic hinge structures 4, the design of the amorphous metal shrapnel 1 surrounding the hinge structure 4 can form a spring-like structure around the hinge, thereby greatly improving the performance of the glasses leg in resisting external force breakage; on the other hand, the amorphous metal shrapnel 1 has good elastic recovery ability and wear resistance, and will not produce deformation or elasticity reduction during long-term use.

[0047] As shown in Figures 1-6, in one embodiment, a limiting component 5 is further included, and the limiting component 5 includes a limiting portion 51 and a positioning member. The other end of the amorphous metal spring 1 is connected to the limiting portion 51, and a positioning member is provided on the second hinge portion 42; when the amorphous metal elastic member is in the initial state, the limiting portion 51 and the positioning member do not contact each other; when the glasses leg is unfolded to approximately 90° and further expanded outward by external force, the distance between the limiting portion 51 and the positioning member gradually shrinks until they abut against each other to limit the unfolding angle of the glasses leg.

[0048] Specifically, during the unfolding of the glasses leg, the amorphous metal spring 1 rotates with the limiting portion 51, and the distance between the limiting portion 51 and the positioning member gradually decreases; when the glasses leg is unfolded to approximately 90° and further expanded outward by external force, the limiting portion 51 and the positioning member abut against each other to limit the unfolding angle of the glasses leg; thereby avoiding the amorphous metal spring 1 from undergoing large deformation when subjected to a large external force, further improving the amorphous metal spring 1's resistance to external force breakage, and during long-term use, the amorphous metal spring 1 will not deform or lose its elasticity.

[0049] As shown in FIG. 1-6 , in one embodiment, the limiting portion 51 is strip-shaped, and the length of the limiting portion 51 is greater than the distance between the inner walls of the two second hinged portions 42 and less than the distance between the outer walls of the two second hinged portions 42 .

[0050] Specifically, a positioning piece is provided on the second hinge part 42; in the process of gradually unfolding the glasses leg, the amorphous metal spring 1 rotates with the limiting part 51, and the distance between the limiting part 51 and the positioning piece gradually decreases; when the glasses leg is unfolded to approximately 90° and further expanded outward by external force, the limiting part 51 and the positioning piece abut against each other to limit the unfolding angle of the glasses leg; if the length of the limiting part 51 is less than the distance between the inner walls of the two second hinge parts 42, the limiting part 51 cannot abut against the positioning piece; if the length of the limiting part 51 is greater than the distance between the outer walls of the two second hinge parts 42, the volume of the amorphous metal elastic hinge component will be increased, which is easy to contact with the user's skin and reduce the wearer's comfort.

[0051] As shown in Figures 1-4, in one embodiment, the positioning member includes a first positioning member 52, and the side surface of the second connecting portion 3 close to the limiting portion 51 is the first positioning member 52. When the limiting portion 51 rotates with the amorphous metal spring 1, the limiting portion 51 gradually approaches the first positioning member 52 until they abut against each other to limit the unfolding angle of the glasses leg.

[0052] Specifically, when the temples of the glasses are in a folded state, the limiting portion 51 is away from the first positioning member 52; when the amorphous metal spring 1 rotates, it drives the limiting portion 51 to rotate, and as the unfolding angle of the temples increases, the limiting portion 51 gradually approaches the first positioning member 52 until they abut against each other to limit the unfolding angle of the temples; when the temples of the glasses are in an unfolded state, the limiting portion 51 abuts against the first positioning member 52 to limit the unfolding angle of the temples, reduce the stress on the amorphous metal spring 1 when bending at a large angle and improve the bending resistance of the hinge structure 4, thereby extending the service life of the amorphous metal spring 1 and the hinge structure 4.

[0053] As shown in Figures 5-6, in one embodiment, the positioning member includes a second positioning member 53, and an arc segment is formed on the second hinge portion 42 with the rotation axis of the hinge structure 4 as the center of the circle, and a movable groove 54 is formed on the arc segment. The amorphous metal spring 1 is located between the overlapping areas of the projections of the two second hinge portions 42, and the two ends of the limiting portion 51 rotate in the movable groove 54. The second positioning member 53 is arranged at the end of the movable groove 54; when the limiting portion 51 rotates in the movable groove 54 with the amorphous metal spring 1, as the expansion angle of the glasses leg increases, the limiting portion 51 gradually approaches the second positioning member 53 until they abut against each other to limit the expansion angle of the glasses leg.

[0054] Specifically, when the temples of the glasses are in a folded state, the end of the limiting portion 51 is embedded in the movable groove 54 and away from one end of the second positioning member 53; when the amorphous metal spring 1 rotates, it drives the limiting portion 51 to rotate, and as the unfolding angle of the temples increases, the limiting portion 51 gradually approaches the second positioning member 53 until they abut against each other to limit the unfolding angle of the temples; when the temples of the glasses are in an unfolded state, the limiting portion 51 abuts against the second positioning member 53 to limit the unfolding angle of the temples, reduce the stress on the amorphous metal spring 1 when bending at a large angle and improve the bending resistance of the hinge structure 4, thereby extending the service life of the amorphous metal spring 1 and the hinge structure 4.

[0055] On the other hand, the present application provides a pair of glasses, comprising the above-mentioned elastic hinge component, a glasses frame and glasses legs, wherein one end of the amorphous metal elastic hinge component for glasses is used to connect to the glasses frame, and the other end of the amorphous metal elastic hinge component for glasses is used to connect to the glasses legs.

[0056] In one embodiment, a left stud and a right stud are respectively provided on both sides of the glasses frame, and the glasses include two elastic hinge components, which are respectively provided at the left stud and the right stud of the glasses.

[0057] Furthermore, the connection method between one of the first connection part 2 and the second connection part 3 and the pile head can also be selected from one of hot melt connection, riveting or screw connection.

[0058] In one embodiment, the other of the first connecting part 2 and the second connecting part 3 is used to connect to one end of the glasses leg, and the connection method between the glasses leg and the first connecting part 2 or the second connecting part 3 is selected from one of hot melt connection, riveting or screw connection.
