Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to an amorphous metal elastic hinge for glasses and the glasses. Background Art

[0002] The hinge of glasses is used to connect the legs of glasses and the frames of glasses. The legs of glasses in the frames of glasses that people usually use are all strip-shaped. The legs of glasses and the frames of glasses are connected by a hinge structure. When the glasses are used, the legs of glasses are fully opened, placed on the ears, and clamped on both sides of the face to fix the rims of the glasses. Long-term opening and closing operations will cause deformation of the hinge position or the legs of glasses, which will cause imbalance of the frames of glasses and affect the user's vision.

[0003] Existing improvements to the hinge structure, as shown in Chinese patent 202221615601.X, on the one hand, by arranging a spring sheet at the position of the hinge structure so that it can be adaptively deformed, thereby improving the comfort and deformation resistance of the glasses. However, in order to ensure that the spring sheet has good elasticity, it needs to be set to a lower thickness, but this setting brings another problem, that is, when the external force bends the glasses leg, the spring sheet is the direct tensile force-bearing 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; on the other hand, by adding a spring sheet at the position of the hinge structure so that it can be adaptively deformed, thereby improving the comfort and deformation resistance of the glasses, however, it will cause the hinge structure to be too large, thereby affecting the wearing comfort of the wearer; therefore, how to overcome the above-mentioned technical problems and defects has become a key problem that needs to be solved.

DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] In the description of the present invention, it should be understood that the terms "side", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

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

[0030] like Figure 1-6 As shown, in one embodiment, the present invention provides an amorphous metal elastic hinge for glasses, including an amorphous metal spring 1, a first connecting part 2 and a second connecting part 3, one end of the first connecting part 2 is provided with a first hinge part 41, and one end of the second connecting part 3 is provided with a second hinge part 42; the first hinge part 41 and the second hinge part 42 are hinged to form a hinge structure 4; one end of the amorphous metal spring 1 is connected to the first hinge part 41, and the other end of the amorphous metal spring 1 is a free end and a gap is left between the hinge structure 4; when the temple 6 of the glasses is unfolded to approximately 90°, the other end of the amorphous metal spring 1 abuts against the second connecting part 3 to provide elasticity for the temple 6 to further expand outward; when the temple 6 of the glasses is further expanded outward from approximately 90°, the gap between the other end of the amorphous metal spring 1 and the hinge structure gradually decreases until the amorphous metal spring 1 abuts against the hinge structure.

[0031] Specifically, the first hinge part 41 and the second hinge part 42 are hinged to form a hinge structure 4. Compared with other existing elastic hinge structures 4, the amorphous metal spring 1 is directly led out from the first hinge part 41, so as to make full use of the space, reduce the volume of the elastic hinge, and avoid the problem of aesthetics or wearing comfort caused by the excessive volume of the elastic hinge. When the temple 6 of the glasses is further expanded from approximately 90° due to impact or improper use (such as violent bending), 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, thereby realizing direct force conduction between the hinge structure and the second connecting part 3, and avoiding the amorphous metal spring 1 from breaking as a direct tensile stress point; the setting of the hinge structure 4 can reduce the external force on the amorphous metal spring 1 and improve the resistance of the amorphous metal spring 1 to external force breakage.

[0032] In one embodiment, the amorphous metal spring 1 is selected from one of a zirconium-based amorphous alloy spring, a copper-based amorphous alloy spring, an iron-based amorphous alloy spring, a magnesium-based amorphous alloy spring and a titanium-based amorphous alloy spring.

[0033] In a preferred embodiment, the amorphous metal spring 1 is selected from zirconium-based amorphous alloy.

[0034] The material strength of zirconium-based amorphous alloy is high, with a tensile strength of 800-1500MPa, 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 accessories and improving the comfort of the wearer. 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 alloy is 440-540Hv, far exceeding that of stainless steel and titanium alloy, and 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 material is 0.6-1.5%, which is 6 times higher than that of 316 stainless steel, with better elasticity and better wearing comfort.

[0035] like Figure 1-6 As shown, in one embodiment, the number of the second hinged parts 42 is two, the number of the first hinged parts 41 is one, and the two second hinged parts 42 are arranged on both sides of the first hinged part 41; the second hinged part 42 is annular, the first hinged part 41 and the second hinged part 42 are coaxially arranged, and a hinge screw 43 is arranged to pass through the first hinged part 41 and the second hinged parts 42 located on both sides of the first hinged part 41 to form a hinge structure 4, and the hinge screw 43 is fixed on the two second hinged parts 42, and the first hinged part 41 and the hinge screw 43 rotate relative to each other.

[0036] Through the above-mentioned structural arrangement, 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 unfolding angle of the glasses leg 6 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. It can be seen that direct force conduction is achieved between the hinge structure and the second connecting part 3, avoiding the amorphous metal spring 1 from breaking as a direct tensile stress point; the arrangement 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 for glasses.

[0037] The second hinged part 42 is arranged at one end of the second connecting part 3, and the first hinged part 41 is arranged at one end of the first connecting part 2. A hinge screw 43 is arranged to pass through the first hinged part 41 and the second hinged part 42 located on both sides of the first hinged part 41 to form a hinge structure 4, so that the first hinged part 41, the second hinged part 42 and the hinge screw 43 are relatively rotatable. Since the first hinged part 41 and the second hinged part 42 are both located at the center of the circle, the support part and the amorphous metal spring sheet 1 are subjected to balanced force, thereby extending the service life of the elastic hinge parts.

[0038] like Figure 1-6As shown, in one embodiment, the amorphous metal spring 1 is disposed around the hinge structure 4 .

[0039] Specifically, 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 comfort of the wearer and avoid the clamping effect of the glasses leg 6. 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 is reduced, and the problem of aesthetics or wearing comfort caused by the excessive volume of the elastic hinge is avoided. When the glasses leg 6 is further expanded from approximately 90° due to impact or improper use (such as violent bending), 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, thereby realizing direct force conduction between the hinge structure and the second connecting part 3, avoiding the amorphous metal spring 1 from being broken as a direct tensile stress point; the setting of the hinge structure 4 can reduce the external force on the amorphous metal spring 1 and improve the resistance of the amorphous metal spring 1 to external force fracture.

[0040] like Figure 1-2 As shown, in one embodiment, the first hinge portion 41 is annular, and the amorphous metal spring 1 is led out from the outer wall of the first hinge portion 41 along the circumference of the first hinge portion 41 .

[0041] Specifically, the amorphous metal spring 1 of the present application is led out from the outer wall of the first hinge part 41 along the circumference of the first hinge part 41 to form a structure in which the amorphous metal spring 1 is arranged around the hinge structure 4. The internal space of the amorphous metal spring 1 is filled by the hinge structure 4 to achieve full utilization of the space, reduce the volume of the elastic hinge, and avoid the problem of aesthetics or wearing comfort caused by the excessive volume of the elastic hinge. When the temple 6 of the glasses is further expanded from approximately 90° due to impact or improper use (such as violent bending), 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, thereby realizing direct force conduction between the hinge structure and the second connecting part 3, avoiding the amorphous metal spring 1 from breaking as a direct tensile stress point; the setting of the hinge structure 4 can reduce the external force on the amorphous metal spring 1 and improve the resistance of the amorphous metal spring 1 to external force breakage.

[0042] Specifically, the amorphous metal spring 1 is arc-shaped, and its arc is greater than or equal to 45°.

[0043] Amorphous metal itself has high elasticity, and 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 shrapnel 1 is 90°-180°. Specifically, the curvature of the amorphous metal shrapnel 1 is any point value among 45°, 60°, 75°, 90°, 105°, 120°, 135°, 150°, 165° or 180°, or a range value consisting of any two point values.

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

[0046] like Figure 3-4 As shown, in a preferred embodiment, the first hinge part 41 is arc-shaped, and a gap 411 is provided between the two ends of the first hinge part 41. One end of the amorphous metal spring 1 is connected to the outer wall of the first hinge part 41. When the temple 6 is further expanded outward from approximately 90°, the gap 411 at the two ends of the first hinge part 41 gradually shrinks.

[0047] Specifically, by setting the first hinge part 41 to be an arc shape, compared with other existing elastic hinge structures 4, one end of the amorphous metal spring 1 is connected to the outer wall of the first hinge part 41, 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 comfort of the wearer and avoid the clamping effect of the glasses leg 6. At the same time, the internal space of the amorphous metal spring 1 is also filled by the hinge structure 4, realizing full utilization of the space, reducing the volume of the elastic hinge, and avoiding the problem of aesthetics or wearing comfort caused by the elastic hinge being too large.

[0048] When the temple 6 of the glasses is further expanded outward from approximately 90° due to impact or improper use (such as violent bending), 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; at the same time, the gap 411 at both ends of the first hinge part 41 gradually decreases; thereby, direct force conduction between the first hinge part 41 and the amorphous metal spring 1 can be achieved, thereby preventing the amorphous metal spring 1 from breaking as a direct tensile stress point; the setting of the hinge structure 4 can reduce the external force on the amorphous metal spring 1, and improve the resistance of the amorphous metal spring 1 to external force breakage.

[0049] like Figure 5-6 As shown, in another preferred embodiment, the first hinge part 41 is arc-shaped, and a gap 411 is provided between the two ends of the first hinge part 41, and one end of the amorphous metal spring 1 is connected to one end of the first hinge part 41, so that the amorphous metal spring 1 and the first hinge part 41 form a continuous spiral structure.

[0050] Specifically, by setting the first hinge part 41 to be an arc shape, compared with other existing elastic hinge structures 4, one end of the amorphous metal spring 1 is connected to one end of the first hinge part 41, so that the amorphous metal spring 1 serves as an extension of the first hinge part 41 and forms an integrated structure, ensuring that the amorphous metal spring 1 has a sufficiently long elastic section, which can improve the comfort of the wearer and avoid the clamping effect of the glasses leg 6. At the same time, one end of the amorphous metal spring 1 is connected to one end of the first hinge part 41, so that the volume of the first hinge part 41 is reduced, thereby reducing the volume of the elastic hinge and avoiding the problem of aesthetics or wearing comfort caused by the excessive volume of the elastic hinge.

[0051] When the temple 6 of the glasses is further expanded outward from approximately 90° due to impact or improper use (such as violent bending), the gap between the other end of the amorphous metal spring 1 and the hinge structure gradually decreases, providing an elastic effect; at the same time, the gap 411 between the other end of the first hinge part 41 and the amorphous metal spring 1 gradually decreases until the other end of the first hinge part 41 abuts against the amorphous metal spring 1; thereby, direct force conduction between the first hinge part 41 and the amorphous metal spring 1 can be achieved, avoiding the amorphous metal spring 1 from breaking as a direct tensile stress point; the setting of the hinge structure 4 can reduce the external force on the amorphous metal spring 1 and improve the resistance of the amorphous metal spring 1 to external force breakage.

[0052] like Figure 7-8 As shown, in one embodiment, a gasket 412 is further included. Two gaskets 412 are provided. The two gaskets 412 are respectively located on both sides of the first hinge part 41 and embedded in the first hinge part 41 .

[0053] Specifically, the gasket 412 includes an annular piece 4121 and a cylinder 4122, the annular piece 4121 is provided with a through hole at a position corresponding to the first hinge part 41, the cylinder 4122 is connected to the through hole of the annular piece 4121 and extends in a direction perpendicular to the plane where the annular piece 4121 is located, the cylinder 4122 is embedded in the first hinge part 41, the outer wall of the cylinder 4122 is in contact with the inner wall of the first hinge part 41, and the annular piece 4121 is arranged on the outer side of the first hinge part 41.

[0054] Furthermore, two gaskets 412 are provided, respectively located on both sides of the first hinge part 41. The material of the gasket 412 is copper. The gasket 412 has a self-lubricating effect, which can reduce the friction between the structures 4, thereby improving the wear resistance of the hinge structure 4 and extending the service life of the hinge structure 4.

[0055] like Figure 1-6 As shown, in one embodiment, the first hinge portion 41 and the non-metal spring sheet 2 are an integrally formed structure.

[0056] Specifically, the first hinge part 41 and the non-metal spring sheet 2 are an integrally formed structure, which, on the one hand, reduces the volume of the elastic hinge and can effectively reduce material costs, thereby improving the comfort of the wearer and avoiding the clamping effect of the temple 6 of the glasses. At the same time, compared with other existing elastic hinge structures 4, the design of the amorphous metal spring sheet 1 surrounding the hinge structure 4 can form a spring-like structure surrounding the hinge, thereby greatly improving the performance of the temple 6 in resisting external force breakage; on the other hand, the amorphous metal spring sheet 1 has good elastic recovery ability and wear resistance, and does not produce deformation and elasticity reduction during long-term use.

[0057] like Figure 1-6 As shown, in one embodiment, it also includes a limit component 5, which includes a limit portion 51 and a positioning member 52. The other end of the amorphous metal spring 1 is connected to the limit portion 51, and the positioning member 52 is provided on the second hinge portion 42; when the temple 6 is in a folded state, the limit portion 51 and the positioning member 52 do not contact each other; when the temple 6 is unfolded to approximately 90°, the limit portion 51 and the positioning member 52 abut against each other to limit the unfolding angle of the temple 6.

[0058] Specifically, during the unfolding of the temple 6, the amorphous metal spring 1 rotates with the limiting portion 51, and the distance between the limiting portion 51 and the positioning member 52 gradually decreases; when the temple 6 is unfolded to approximately 90° and further expanded outward by external force, the limiting portion 51 and the positioning member 52 abut against each other to limit the unfolding angle of the temple 6; thereby preventing the amorphous metal spring 1 from undergoing a 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 does not deform or lose its elasticity.

[0059] like Figure 1-6 As shown, 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; the side surface of the second connecting portion 3 close to the limiting portion 51 is the positioning member 52, and when the limiting portion 51 rotates with the amorphous metal spring 1, the limiting portion 51 gradually approaches the positioning member 52 until they abut against each other to limit the unfolding angle of the eyeglass leg 6.

[0060] Specifically, a positioning piece 52 is provided on the second hinge part 42; in the process of gradually unfolding the temple 6, the amorphous metal spring sheet 1 rotates with the limiting part 51, and the distance between the limiting part 51 and the positioning piece 52 gradually decreases; when the temple 6 is unfolded to approximately 90° and then further expanded outward by external force, the limiting part 51 and the positioning piece 52 abut against each other to limit the unfolding angle of the temple 6; 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 52; 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 will be increased, which is easy to contact with the user's skin and reduce the wearer's comfort.

[0061] Specifically, when the temple 6 of the glasses is in a folded state, the limiting portion 51 is away from the positioning piece 52; when the amorphous metal spring 1 rotates, it drives the limiting portion 51 to rotate, and as the unfolding angle of the temple 6 increases, the limiting portion 51 gradually approaches the positioning piece 52 until they abut against each other to limit the unfolding angle of the temple 6; when the temple 6 of the glasses is in an unfolded state, the limiting portion 51 abuts against the positioning piece 52 to limit the unfolding angle of the temple 6, reducing the stress on the amorphous metal spring 1 under large-angle bending and improving the bending resistance of the hinge structure 4, thereby extending the service life of the amorphous metal spring 1 and the hinge structure 4.

[0062] like Figure 1-6 As shown, another aspect of the present invention provides a pair of glasses, comprising the above-mentioned amorphous metal elastic hinge for glasses, a glasses frame and glasses legs 6, wherein the first connecting portion 2 and the second connecting portion 3 can be connected to the glasses frame and the glasses legs 6 respectively in an interchangeable manner.

[0063] In one embodiment, a left stud and a right stud are respectively arranged on both sides of the glasses frame, and the glasses include two amorphous metal elastic hinges for glasses, which are respectively arranged at the left stud and the right stud of the glasses.

[0064] Furthermore, one of the first connection part 2 and the second connection part 3 is connected to the pile head, and the connection method can also be selected from one of hot melt connection, riveting or screw connection.

[0065] In one embodiment, the other one of the first connecting part 2 and the second connecting part 3 is used to connect to the temple 6, and the connection method between the temple 6 and the first connecting part 2 or the second connecting part 3 is selected from one of hot melt connection, riveting or screw connection.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
