Technical Field
[0001] This utility model relates to the field of eyeglasses technology, specifically to an eyeglasses hinge structure that allows for free movement at multiple angles. Background Technology
[0002] Traditional eyeglasses hinges only allow the temples to rotate in the direction of opening and closing. The temples and lenses can only rotate on the same horizontal plane. However, each wearer's facial contours are different. When the frame is stable on the wearer's nose, the differences in facial contours will lead to different opening angles of the temples. Furthermore, due to differences in ear height, the temples may also need to rotate vertically relative to the frame to fit the wearer's face.
[0003] Therefore, if the structure of traditional eyeglass hinges can be changed to give the temples a greater range of freedom, then the temples can more flexibly adapt to the wearer's facial contours and extend into more variations. Utility Model Content
[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a multi-angle freely movable eyeglass hinge structure. The technical solution of this utility model is as follows: A multi-angle freely movable eyeglass hinge structure includes a frame, temples, a first connector, a second connector, a hook connector, and a spring mechanism. The first connector includes a fixed end connected to the frame, a first contact plane, and a hinge end, the hinge end having a first hinge hole arranged horizontally. The second connector has a vertical groove extending through one end in a vertical direction to engage with the hinge end, and a horizontal groove extending through the other end in a horizontal direction, the horizontal groove and the vertical groove communicating to form an inner cavity.
[0005] The slingshot mechanism includes a sliding seat, a telescopic rod, and an elastic reset component. The sliding seat is fixed to the temple and has a second contact plane and a telescopic hole at one end facing the frame. The telescopic rod slides axially with the telescopic hole. The elastic reset component is located in the telescopic hole and is connected to the telescopic rod to drive it to retract into the telescopic hole. The hook component includes a connecting part and a hook part. The connecting part is connected to the telescopic rod, and the hook part is inserted into a horizontal sliding groove and hooked with a first hinge hole.
[0006] The above technical solution is adopted, as shown in the appendix to the instruction manual. Figure 1 , 5As shown, the hook part of the hook connector is connected to the first hinge hole, and the connecting part is elastically telescopically connected to the slingshot mechanism. When the temple rotates vertically and horizontally, the vertical slide and the hinge end form a vertical degree of freedom. The hook connector carries the temple and the slingshot mechanism as a whole. The horizontal degree of freedom is formed by the cooperation between the hook part and the horizontal slide. The connection between the hook part and the first hinge hole is formed with the first connecting part. In this way, the vertical and horizontal synchronous linkage is formed, and the temple can be rotated in a wide range to meet the needs of different wearers.
[0007] A further feature of this invention is that the hinge structure also includes a second connector B. On the end face of the second connector B that abuts against the first contact plane, there are transition arcs at both the upper and lower ends in the vertical direction. On the end face of the second connector B that abuts against the second contact plane, there are transition arcs at both the left and right ends in the horizontal direction. The thickness of the hook portion in the vertical direction is adapted to the height of the horizontal groove and makes a sliding fit.
[0008] The above technical solution is adopted as a specific embodiment of this application, as shown in the appendix to the specification. Figure 1-4 As shown, the second connector is further optimized and set as the structure of the second connector B. By utilizing the cooperation of the transition arc with the first contact plane and the second contact plane, the large-angle twisting process of the temple is made smoother.
[0009] A further feature of this invention is that the hinge structure also includes a hook member B, which includes a disc portion and a hook portion. The disc portion is disposed in a vertical groove and is coaxially hinged with the first hinge hole. The hook portion of the hook member B extends out from the disc portion and extends into the horizontal groove.
[0010] The telescopic rod extends into a horizontal groove at its end near the frame, and an elongated hole is provided at this end along the axial direction. The hook portion is hooked to the elongated hole in the horizontal groove.
[0011] The above technical solution is adopted as a specific embodiment of this application, as shown in the appendix to the specification. Figure 5-7 As shown, the hook and connector mechanism is further optimized and configured as hook and connector B. It is coaxially hinged to the first hinge hole via a disc portion, and a pin is provided to pass through the first hinge hole, the disc portion, and the vertical slide groove to form a hinge connection, thus completing the connection with the first connector. The hook portion of the hook and connector extends into the horizontal slide groove and hooks with the further optimized elongated hole on the telescopic rod.
[0012] This second embodiment fulfills the requirement for temple freedom in this application with another connection design.
[0013] A further feature of this invention is that the hinge structure also includes a first connector B and a second connector C. The first connector B has two hinge ends spaced apart, and the disc portion is inserted between the two hinge ends to form a coaxial hinge connection.
[0014] The second contact plane of the sliding seat is provided with a groove that runs through it in the vertical direction;
[0015] The width of the vertical groove of the second connector C is adapted to the sum of the widths of the two hinge ends and the disc portion. The second connector C is provided with protrusions that extend into the groove and match each other in shape.
[0016] A further feature of this invention is that the cross-sectional shape of the groove and the protrusion is triangular.
[0017] In the second embodiment, the above technical solution is further improved by providing interlocking triangles, semicircles, etc., at the second contact plane, as shown in the appendix to the specification. Figure 5 The groove and protrusion structure shown facilitates the deflection of the second connector relative to the sliding seat, thereby guiding the horizontal rotation of the temple.
[0018] A further feature of this invention is that the slingshot mechanism also includes an axial limiting ring. The outer diameter of the axial limiting ring is adapted to the diameter of the telescopic hole, and the inner diameter is adapted to the diameter of the telescopic rod for axial sliding fit. The axial limiting ring is located at the opening of the telescopic hole and is coaxially connected to the opening for axial fixation. A limiting flange is provided at one end of the telescopic rod near the bottom of the telescopic hole. The elastic reset element is a spring, which is sleeved on the telescopic rod and located between the axial limiting ring and the limiting flange.
[0019] Using the above technical solution, the slingshot mechanism utilizes an axial limiting ring, a limiting flange, and a spring to form an axial elastic sliding mechanism for the telescopic rod. When the temple needs to be twisted, the hook-connector pulls the telescopic rod to extend elastically out of the telescopic hole. When the temple is retracted, the spring drives the telescopic rod to retract into the telescopic hole, causing all components to return to their original position. At the same time, the damping of the spring makes the temple twisting smoother.
[0020] A further feature of this invention is that the fixed end of the first connector is inserted and fixed to the head of the frame post, and the fixed end is provided with a positioning pin hole.
[0021] The above technical solution makes the connection between the first connector and the head of the mirror frame post more stable.
[0022] The beneficial effects of this utility model are as follows: Through the coordinated design of the first connector, the second connector, the hook, and the slingshot mechanism, the temples can simultaneously twist and turn in the horizontal and vertical directions, thereby creating a wide range of freedom in the posture changes of the temples to adapt to the needs of various wearers' facial contours. The elastic damping formed by the slingshot mechanism makes the twisting of the temples smoother and can guide the components back to their original position when not worn.
[0023] The first connector B, the second connector B, the hook connector B, and the second connector C have been further optimized in design. With different structural designs, they have achieved the purpose of temple torsion in this application, providing personalized options. Attached Figure Description

[0034] like Figure 1-7 As shown, a multi-angle freely movable eyeglass hinge structure includes a frame 1, temples 2, a first connector 4, a second connector, a hook 3, and a slingshot mechanism. The first connector 4 includes a fixed end 41 connected to the frame 1, a first contact plane 42, and a hinge end 43. The hinge end 43 has a first hinge hole 44 in the horizontal direction.

The horizontal groove 52 and the vertical groove 51 communicate to form an inner cavity.
[0035] The slingshot mechanism includes a sliding seat 61, a telescopic rod 62, and an elastic reset member 63. The sliding seat 61 is fixed to the temple 2, and a second contact surface 64 and a telescopic hole 65 are provided at one end facing the frame 1. The telescopic rod 62 and the telescopic hole 65 are axially slidingly engaged. The elastic reset member 63 is disposed in the telescopic hole 65 and is connected to the telescopic rod 62 to drive it to retract into the telescopic hole 65. The hook member 3 includes a connecting part 31 and a hook part 32. The connecting part 31 is connected to the telescopic rod 62, and the hook part 32 is inserted into the horizontal sliding groove 52 and hooked with the first hinge hole 44.
[0036] As per the instruction manual Figure 1 , 5As shown, the hook part 32 of the hook member 3 is hooked to the first hinge hole 44, and the connecting part 31 is elastically telescopically connected to the slingshot mechanism. When the temple 2 rotates in a vertical and horizontal direction, the vertical slide 51 and the hinge end 43 form a vertical degree of freedom. The hook member 3 carries the temple 2 and the slingshot mechanism as a whole. The horizontal degree of freedom is formed by the cooperation between the hook part 32 and the horizontal slide 52. The connection between the hook part 32 and the first hinge hole 44 is formed with the first connecting member 4. In this way, the vertical and horizontal synchronous linkage is formed, and the temple 2 can be rotated in a wide range to meet the needs of different wearers.
[0037] The hinge structure also includes a second connector B72. On the end face of the second connector B72 that abuts against the first contact plane 42, there are transition arcs 71 at both the upper and lower ends in the vertical direction. On the end face of the second connector B72 that abuts against the second contact plane 64, there are transition arcs 71 at both the left and right ends in the horizontal direction. The thickness of the hook portion 32 in the vertical direction is adapted to the height of the horizontal slide groove 52 and makes a sliding fit.
[0038] As a specific embodiment of this application, as shown in the appendix to the specification. Figure 1-4 As shown, the second connector is further optimized and set as the structure of the second connector B72. By utilizing the cooperation between the transition arc 71 and the first contact plane 42 and the second contact plane, the large-angle torsion process of the temple 2 is made smoother.
[0039] The hinge structure also includes a hook member B73, which includes a disc portion 731 and a hook portion 32. The disc portion 731 is disposed in the vertical slide groove 51 and is coaxially hinged to the first hinge hole 44. The hook portion 32 of the hook member B73 extends out from the disc portion 731 and extends into the horizontal slide groove 52.
[0040] The end of the telescopic rod 62 near the frame 1 extends into the horizontal slide groove 52, and the end is provided with an elongated hole 621 along the axial direction. The hook part 32 is hooked to the elongated hole 621 in the horizontal slide groove 52.
[0041] As a specific embodiment of this application, see the appendix to the specification. Figure 5-7 As shown, the hook member 3 is further optimized into a hook member B73 mechanism. It is coaxially hinged to the first hinge hole 44 via the disc portion 731, and a pin is provided to pass through the first hinge hole 44, the disc portion 731, and the vertical slide groove 51 for hinge connection, thus completing the connection with the first connecting member 4. The hook portion 32 of the hook member 3 extends into the horizontal slide groove 52 and hooks with the further optimized elongated hole 621 on the telescopic rod 62.
[0042] This second embodiment fulfills the requirement of 2 degrees of freedom for the temple of this application with another connection design.
[0043] The hinge structure also includes a first connector B74 and a second connector C75. The first connector B74 has two hinge ends 43 spaced apart, and the disc portion 731 is inserted between the two hinge ends 43 to form a coaxial hinge connection.
[0044] The second contact plane 64 of the sliding seat 61 is provided with a groove 611 extending through it in the vertical direction;
[0045] The width of the vertical groove 51 of the second connector C75 is adapted to the sum of the widths of the two hinge ends 43 and the disc portion 731. The second connector C75 is provided with a protrusion 751 that extends into the groove 611 and matches each other in shape.
[0046] The cross-sectional shape of both the groove 611 and the protrusion 751 is triangular.
[0047] In the second embodiment, a triangle, a semi-circle, or similar shape that fits together is further provided at the second contact plane 64, as shown in the appendix to the specification. Figure 5 The groove 611 and protrusion 751 structure shown facilitates the deflection of the second connector relative to the sliding seat 61, thereby guiding the horizontal rotation of the temple 2.
[0048] The slingshot mechanism also includes an axial limiting ring 66. The outer diameter of the axial limiting ring 66 is adapted to the diameter of the telescopic hole 65, and the inner diameter is adapted to the diameter of the telescopic rod 62 for axial sliding fit. The axial limiting ring 66 is disposed at the opening of the telescopic hole 65 and is coaxially connected to the opening for axial fixation. A limiting flange 622 is provided at one end of the telescopic rod 62 near the bottom of the telescopic hole 65. The elastic reset member 63 is a spring, which is sleeved on the telescopic rod 62 and located between the axial limiting ring 66 and the limiting flange 622.
[0049] The slingshot mechanism utilizes the axial limiting ring 66, the limiting flange 622, and the spring to form the axial elastic sliding of the telescopic rod 62. When the temple 2 needs to be twisted, the hook 3 pulls the telescopic rod 62 to extend elastically out of the telescopic hole 65. When the temple 2 is retracted, the spring drives the telescopic rod 62 to retract into the telescopic hole 65, causing all components to return to their original position. At the same time, the damping of the spring makes the twisting of the temple 2 smoother.
[0050] The fixed end 41 of the first connector 4 is inserted and fixed to the head of the frame 1. The fixed end 41 is provided with a positioning pin hole 411.
[0051] This makes the connection between the first connector 4 and the head of the frame 1 more stable.
[0052] This application utilizes the coordinated design of the first connector 4, the second connector, the hook 3, and the slingshot mechanism to allow the temple 2 to rotate synchronously in both horizontal and vertical directions. This enables the temple 2 to achieve a wide range of freedom in its posture changes, adapting to the needs of various wearers' facial contours. The elastic damping provided by the slingshot mechanism makes the rotation of the temple 2 smoother and guides the components back to their original position when not in use.
[0053] The first connector B74, the second connector B72, the hook connector B73, and the second connector C75, which are further optimized in design, achieve the purpose of torsion of the temple 2 in this application with different structural designs, providing personalized options.
