Description

Technical Field

[0001] This invention relates to the field of eyewear technology, and in particular to a hinge module and eyewear using the hinge module. Background Technology

[0002] Currently, eyeglasses typically use single-axis rotation to fold the temples for easy storage. However, due to differences in head size, single-axis glasses can cause discomfort and affect user experience. This is especially true for virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR) glasses, where wearing them can even affect the clarity of binocular images.

[0003] In some related technologies, the hinge of certain eyeglasses allows for both temple folding and outward rotation, catering to users with different head widths and improving comfort. However, for users with different head lengths, head shapes, and nose-to-ear distances, these single-axis outward-rotating glasses can still cause discomfort. Summary of the Invention

[0038] In one embodiment, the first rotating hole includes two holes, which are coaxially arranged and located on opposite sides of the receiving groove;

[0039] The first connector includes a first connecting part and two rotating arms disposed at both ends of the first connecting part. The two rotating arms and the first connecting part form a clearance groove. Each rotating arm has a mounting hole at the end away from the first connecting part.

[0040] The first rotating shaft is sequentially inserted into the mounting hole, the first rotating hole, and the damping groove, and both ends of the first rotating shaft are fixed in the two mounting holes so that part of the rotating base is accommodated in the clearance groove. The end of the first elastic member away from the second rotating hole elastically abuts against the first connecting part.

[0041] In one embodiment, the first rotating shaft includes a rotating shaft portion and mounting portions connected to both ends of the rotating shaft portion.

[0046] The present invention also proposes a pair of eyeglasses, the eyeglasses comprising:

[0047] Picture frames;

[0048] Temples; and

[0049] The hinge module described above has a second connector connected to the frame and a first connector connected to the temple.

[0050] The hinge module of this invention features a rotating base with a receiving groove and a first rotating hole, a second rotating hole, and a sliding hole connecting the receiving groove. A first connecting member is rotatably connected to the rotating base via a first rotating shaft engaging with the hole shaft of the first rotating hole. A second connecting member's second rotating shaft rotatably passes through the second rotating hole, and a sliding shaft movably passes through the sliding hole. This allows the second connecting member to rotatably connect to the rotating base, with the axial directions of the first and second rotating shafts forming an angle. This enables the hinge module to achieve multi-axis rotation; that is, the hinge module can rotate relative to the rotating base via the first connecting member around the first rotating shaft, and simultaneously rotate relative to the second connecting member via the rotating base around the second rotating shaft, achieving multi-degree-of-freedom rotation. When applied to eyeglasses, the temples of the eyeglasses are connected to the frame via the hinge module, allowing the temples to rotate relative to the rotating base and the frame via the first connecting member around the first rotating shaft. Meanwhile, the temples can also rotate relative to the frame via the rotating base around the second axis. This means the temples and frame can achieve multi-degree-of-freedom rotational hinges through a multi-axis hinge structure, making the glasses suitable for different head shapes, such as different head lengths, head shapes, and nose-ear distances, thus improving user comfort and versatility. Simultaneously, by placing one end of the first elastic element within a receiving groove and providing a damping groove on the first elastic element that abuts against the first axis, the other end of the first elastic element elastically abuts against the first connecting member. Thus, when the first connecting member of the hinge module rotates relative to the rotating base around the first axis, the first elastic element provides damping for the rotation of the first connecting member. Furthermore, the second elastic element is placed within the receiving groove and elastically abuts against the sliding shaft, providing elastic limiting and damping functions for the rotation of the rotating base relative to the second connecting member, thereby offering different rotation angles.

[0073] Currently, eyeglasses typically use single-axis rotation to fold the temples for easy storage. However, due to differences in head size, single-axis glasses can cause discomfort and affect user experience. This is especially true for virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR) glasses, where wearing them can even affect the clarity of binocular images.

[0074] In some related technologies, the hinge of certain eyeglasses allows for both temple folding and outward rotation, catering to users with different head widths and improving comfort. However, for users with different head lengths, head shapes, and nose-to-ear distances, these single-axis outward-rotating glasses can still cause discomfort.

[0075] Meanwhile, to achieve multi-axis rotation, the temples and frames of eyeglasses usually employ multiple single-axis structures to achieve rotation on different axes. This results in a complex and dispersed hinge structure, a large structural volume, and a bulky overall structure, making disassembly quite complicated.

[0076] Based on the above concepts and problems, this invention proposes a hinge module 100, which can be applied to eyeglasses 800. Eyeglasses 800 can be eyeglasses worn by people for nearsightedness, presbyopia, astigmatism, sun protection, or decorative purposes. Eyeglasses 800 can also be smart glasses, such as virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR) glasses, etc., without limitation.

[0077] In this embodiment, the glasses 800 includes a frame 810 and temples 820, with the temples 820 connected to the frame 810 via a hinge module 100. The hinge module 100 is an integrated hinge structure that enables the hinged connection between the frame 810 and the temples 820, while also facilitating overall assembly and disassembly. It is understood that the connection between the temples 820 and the frame 810 via the hinge module 100 allows the glasses 800 to not only fold and store, be worn normally, and flip outwards relative to the frame 810, but also to rotate and adjust the temples 820 relative to the frame 810 in another direction. This makes the glasses 800 suitable for users with different head lengths, head shapes, and nose-ear distances, improving user comfort and versatility.

[0078] Please refer to the reference. Figures 1 to 7 As shown, in this embodiment of the invention, the hinge module 100 includes a rotating base 1, a first connector 2, a first elastic member 3, a second connector 4, and a second elastic member 5. The rotating base 1 is provided with a receiving groove 11 and a first rotating hole 131, a second rotating hole 121, and a sliding hole 122 communicating with the receiving groove 11. The first connector 2 is rotatably connected to the rotating base 1 through a first rotating shaft 24 cooperating with the hole shaft of the first rotating hole 131. One end of the first elastic member 3 is received in the receiving groove 11 and is provided to rotatably abut against the first rotating shaft 24. The damping groove 321, the other end of the first elastic member 3 elastically abuts against the first connecting member 2, the second connecting member 4 is provided with a second rotating shaft 41 and a sliding shaft 42 spaced apart, the second rotating shaft 41 rotatably passes through the second rotating hole 121 so that the second connecting member 4 is rotatably connected to the rotating base 1, and the sliding shaft 42 movably passes through the sliding hole 122, the second elastic member 5 is accommodated in the receiving groove 11 and elastically abuts against the sliding shaft 42; wherein, the axial direction of the first rotating shaft 24 is set at an angle to the axial direction of the second rotating shaft 41.

[0079] In this embodiment, the hinge module 100 is configured as a rotating base 1, a first connector 2, and a second connector 4. The rotating base 1 is provided with a receiving groove 11 and a first rotating hole 131, a second rotating hole 121, and a sliding hole 122 that connect to the receiving groove 11. One end of the first connector 2 is rotatably connected to the rotating base 1 through a first rotating shaft 24 that engages with the hole shaft of the first rotating hole 131. The other end of the first connector 2 can be used to connect to the temple 820. That is, the temple 820 is rotatably connected to the rotating base 1 through the first connector 2 and the first rotating shaft 24. The second rotating shaft 41 of the second connector 4 is rotatably inserted through the second rotating hole 121, and the sliding shaft 42 is movably inserted through the sliding hole 122, so that the rotating base 1 and the second connector 4 are rotatably connected. The second connector 4 is used to connect to the frame 810. In this way, the temple 820 is rotatably connected to the frame 810 through the hinge module 100.

[0080] It should be noted that, since the axial direction of the first rotating shaft 24 is set at an angle to the axial direction of the second rotating shaft 41, that is, the first connecting member 2 of the hinge module 100 rotates relative to the rotating base 1 around the axial direction of the first rotating shaft 24, and the rotating base 1 rotates relative to the second connecting member 4 around the axial direction of the second rotating shaft 41, thereby enabling the hinge module 100 to rotate with multiple degrees of freedom in multiple axial directions. In this way, the hinge module 100 is applied to the glasses 800, so that the glasses 800 can be worn by users with different head lengths, different head shapes, and different nose-ear distances, improving the user's wearing comfort and versatility. That is, the temple 820 rotates relative to the rotating base 1 and the frame 810 through the first connecting member 2 around the axial direction of the first rotating shaft 24, and the temple 820 rotates relative to the frame 810 through the rotating base 1 around the axial direction of the second rotating shaft 41, thereby enabling the temple 820 to rotate with multiple degrees of freedom relative to the frame 810 in multiple axial directions.

[0081] In this embodiment, by placing one end of the first elastic member 3 within the receiving groove 11 and providing a damping groove 321 on the first elastic member 3 that rotatably abuts against the first rotating shaft 24, and by elastically abutting the other end of the first elastic member 3 against the first connecting member 2, the hinge module 100 utilizes the frictional damping generated by the first elastic member 3 during the rotation of the first connecting member 2 around the axial direction of the first rotating shaft 24 relative to the rotating base 1. This results in a hinge movement with a damped folding feel during the movement of the first connecting member 2, thereby achieving the folding of the temple 820 and providing a damped folding feel and an outward clamping force effect. Simultaneously, by placing the second elastic member 5 within the receiving groove 11 and elastically abutting against the sliding shaft 42, the second elastic member 5 provides resistance to deformation and prevents over-bending failure during the rotation of the hinge module 100 relative to the second connecting member 4 via the axial direction of the second rotating shaft 41 of the rotating base 1.

[0082] The hinge module 100 of the present invention has a receiving groove 11 on a rotating base 1 and a first rotating hole 131, a second rotating hole 121 and a sliding hole 122 communicating with the receiving groove 11. The first connecting member 2 is rotatably connected to the rotating base 1 via a first rotating shaft 24 engaging with the hole shaft of the first rotating hole 131. The second connecting member 4 has a second rotating shaft 41 rotatably passing through the second rotating hole 121, and a sliding shaft 42 movably passing through the sliding hole 122. This allows the second connecting member 4 to be rotatably connected to the rotating base 1, and the axial direction of the first rotating shaft 24 is parallel to that of the second rotating shaft 122. The axial direction of hinge 41 is set at an angle, thereby enabling the hinge module 100 to achieve multi-axis rotation. That is, the hinge module 100 can rotate relative to the rotating base 1 around the first pivot 24 via the first connector 2, and can also rotate relative to the second connector 4 around the second pivot 41 via the rotating base 1, thus achieving multi-degree-of-freedom rotation. When the hinge module 100 is applied to the eyeglasses 800, the temples 820 of the eyeglasses 800 are connected to the frame 810 via the hinge module 100, thereby enabling the temples 820 to rotate around the first pivot 24 via the first connector 2. The rotating base 1 and the frame 810 rotate, and the temple 820 can also rotate relative to the frame 810 via the rotating base 1 around the second axis 41. That is, the temple 820 and the frame 810 can achieve multi-degree-of-freedom rotational hinges through the multi-axis rotation of the hinge module 100, making the glasses 800 suitable for different head shapes of different users, such as users with different head lengths, head shapes, and nose-ear distances, thereby improving the user's wearing comfort and versatility. Simultaneously, by placing one end of the first elastic member 3 within the receiving groove 11, and by providing a [missing information] on the first elastic member 3... The damping groove 321, which rotates and abuts against the first rotating shaft 24, allows the other end of the first elastic member 3 to elastically abut against the first connecting member 2. Thus, when the first connecting member 2 of the hinge module 100 rotates relative to the rotating base 1 around the first rotating shaft 24, the first elastic member 3 provides damping performance for the rotation of the first connecting member 2. The second elastic member 5 is placed in the receiving groove 11 and elastically abuts against the sliding shaft 42. Thus, the second elastic member 5 provides elastic limiting and damping functions for the rotation of the rotating base 1 relative to the second connecting member 4, thereby providing different rotation angles.

[0083] In this embodiment, the axial direction of the first rotating shaft 24 and the axial direction of the second rotating shaft 41 are optionally perpendicular. It can be understood that, with the user wearing glasses 800 and the user's eyes as the light emission direction as a reference, the light emission direction, the axial direction of the first rotating shaft 24, and the axial direction of the second rotating shaft 41 are approximately perpendicular to each other in a three-dimensional coordinate structure. That is, the axial direction of the first rotating shaft 24 and the axial direction of the second rotating shaft 41 are both approximately perpendicular to the light emission direction.

[0084] It should be noted that when the hinge module 100 is used in the glasses 800, such as Figure 14 As shown, the glasses 800 has three states: a folded state, an open state, and an outward-folding state, where the temples 820 rotate relative to the rotating base 1 and the frame 810 via the first connecting member 2 and the first rotating axis 24. Understandably, in the folded state, the temples 820 are close to the frame 810, meaning they are roughly parallel to the frame 810, making the glasses 800 easy to store. In the open state, the two temples 820 are roughly perpendicular to the frame 810, forming a U-shaped wearing cavity with the frame 810. This facilitates the contact between the temples 820 and the user's ears, and the nose pads of the frame 810 contact the user's nose bridge, thus enabling wearing. When the glasses 800 are in the outward-folded position, the two temples 820 are set at approximately an obtuse angle to the frame 810. At this time, the two temples 820 and the frame 810 roughly enclose to form a wide-mouthed U-shaped wearing cavity. The two temples 820 abut against the user's ears and abut against the user's nose bridge through the nose pads of the frame 810, thus achieving wearing. That is, the outward-folded position is suitable for users with wider heads, while the open position is suitable for users with narrower heads.

[0085] At the same time, such as Figure 13 As shown, the glasses 800 has an initial position, a first position, and a second position for the temples 820 to rotate relative to the frame 810 via a rotating base 1 about a second axis 41. In this embodiment, the rotation of the temples 820 relative to the frame 810 about the second axis 41 can optionally be performed when the glasses 800 is in the open state and the everted state. That is, when the glasses 800 is in the open state and the everted state, the temples 820 can rotate relative to the frame 810 about the second axis 41 in the initial position, the first position, and the second position, thus making them suitable for users with different head lengths and different nose-ear distances.

[0086] It should be noted that when the glasses 800 is in the open state, and the temples 820 are in their initial position, the extension direction of the temples 820 is consistent with the extension direction of the connecting or mounting portion of the frame 810; when the temples 820 are in the first or second position, the extension direction of the temples 820 forms a certain angle with the extension direction of the connecting or mounting portion of the frame 810. Optionally, the angle formed by the extension direction of the temples 820 and the extension direction of the connecting or mounting portion of the frame 810 is an acute angle.

[0087] Understandably, taking the plane where the light emanating from the user's two eyes is located when the user wears glasses 800 as the horizontal plane, with glasses 800 in the open and outward-folded states, when the temple 820 is in the first position, the end of the temple 820 away from the frame 810 is above this horizontal plane, and the angle formed by the extension direction of the temple 820 and the horizontal plane is an acute angle; when the temple 820 is in the second position, the end of the temple 820 away from the frame 810 is below this horizontal plane, and the angle formed by the extension direction of the temple 820 and the horizontal plane is an acute angle.

[0088] In one embodiment, the rotating base 1 includes a base plate 12 and a side plate 13. The side plate 13 is disposed around the periphery of the base plate 12 and forms a receiving groove 11 with the base plate 12. The side plate 13 is provided with a first rotating hole 131, and the base plate 12 is provided with a second rotating hole 121 and a sliding hole 122. A clearance notch 132 communicating with the receiving groove 11 is provided on the side of the side plate 13 away from the second rotating hole 121. The end of the first elastic member 3 away from the second rotating hole 121 passes through the clearance notch 132 and elastically abuts against the first connecting member 2.

[0089] In this embodiment, as Figures 1 to 3 , Figures 10 to 12 As shown, the side plate 13 of the rotating base 1 surrounds the periphery of the base plate 12. The side plate 13 is optionally perpendicular to the base plate 12, so that the side plate 13 and the base plate 12 enclose and form a receiving groove 11. Optionally, the base plate 12 is rectangular or elongated. By providing a clearance notch 132 at one end of the side plate 13 adjacent to the base plate 12, the clearance notch 132 is conveniently used to provide clearance and limiting space for the first elastic member 3, so that one end of the first elastic member 3 passes through the clearance notch 132 and elastically abuts against the first connecting member 2.

[0090] Understandably, the side plate 13 is also provided with a first rotating hole 131, which is located at one end of the side plate 13 adjacent to the clearance notch 132. Optionally, the axial direction of the second rotating hole 121 is perpendicular to the axial direction of the first rotating hole 131. This makes the axial direction of the second rotating hole 121 perpendicular to the axial direction of the first rotating hole 131.

[0091] In this embodiment, to prevent the second rotating shaft 41 from affecting the first connecting member 2 in driving the temple 820 to rotate around the first rotating shaft 24, the base plate 12 is provided with a second rotating hole 121 and a sliding hole 122 spaced apart. The second rotating hole 121 is located at the end of the base plate 12 away from the avoidance notch 132. It can be understood that one end of the rotating base 1 is rotatably connected to the second connecting member 4, and the other end of the rotating base 1 is rotatably connected to the first connecting member 2.

[0092] In order to ensure that the rotating base 1 can rotate relative to the second connecting member 4 about the second rotating shaft 41, in one embodiment, the base plate 12 is provided with a rotating cylinder 125 protruding around the second rotating hole 121. The second rotating shaft 41 rotates through the second rotating hole 121 and rotates against the inner wall of the rotating cylinder 125. The second elastic member 5 is elastically limited between the rotating cylinder 125 and the sliding shaft 42.

[0093] Understandable, such as Figure 2 and Figure 3 As shown, by protruding a rotating cylinder 125 on the base plate 12 of the rotating base 1, the rotating cylinder 125 is arranged around the second rotating hole 121. In this way, the second rotating shaft 41 rotates through the second rotating hole 121 and rotates against the inner wall of the rotating cylinder 125, thereby providing the second rotating shaft 41 with rotation and limiting space by the rotating cylinder 125.

[0094] In one embodiment, the sliding hole 122 includes a plurality of sliding holes 122, which are spaced apart around the second rotating hole 121; the second connecting member 4 is provided with a plurality of sliding shafts 42, which are spaced apart around the second rotating shaft 41, and each sliding shaft 42 is movably inserted into a sliding hole 122 and elastically abuts against the second elastic member 5.

[0095] In this embodiment, as Figure 2 , Figure 3 , Figure 6 , Figure 11 and Figure 12 As shown, the number of sliding shafts 42 is the same as the number of sliding holes 122 and the number of second through holes 14, and they are arranged in a one-to-one correspondence. Optionally, the axial direction of the second rotating hole 121 is parallel to the axial direction of the sliding hole 122.

[0096] To facilitate the movement of the sliding shaft 42 along the sliding hole 122 when the rotating base 1 rotates around the second rotating shaft 41, optionally, the sliding hole 122 is arranged in an arc shape with the center of the second rotating hole 121 as the center. In this embodiment, as shown... Figure 2 , Figure 3 , Figure 6 , Figure 11 and Figure 12 As shown, there are three sliding holes 122 and three sliding shafts 42, with the three sliding holes 122 spaced apart around the second rotating hole 121. Optionally, the line connecting the three sliding holes 122 is arranged in a semi-circular arc.

[0097] In one embodiment, the second elastic member 5 includes an arc-shaped portion 51 and a first elastic portion 52 and a second elastic portion 53 connected to both ends of the arc-shaped portion 51. The end of the first elastic portion 52 away from the arc-shaped portion 51 is bent to form a first bent portion 521, and the end of the second elastic portion 53 away from the arc-shaped portion 51 is bent to form a second bent portion 531. The plurality of sliding shafts 42 include a first sliding shaft 421 corresponding to the arc-shaped portion 51, a second sliding shaft 422 corresponding to the first bent portion 521, and a third sliding shaft 423 corresponding to the second bent portion 531. The arc-shaped portion 51 slides against the outer wall of the first sliding shaft 421 and elastically abuts against the outer wall of the rotating cylinder 125. The second sliding shaft 422 movably abuts against the first bent portion 521, and the third sliding shaft 423 movably abuts against the second bent portion 531.

[0098] In this embodiment, as Figure 2 , Figure 7 , Figure 11 and Figure 12 As shown, by setting the second elastic member 5 as an arc-shaped portion 51 and connecting the first elastic portion 52 and the second elastic portion 53 at both ends of the arc-shaped portion 51, the arc-shaped portion 51 of the second elastic member 5 is elastically limited between the outer wall of the first sliding shaft 421 and the outer wall of the rotating cylinder 125. The first bending portion 521 of the first elastic portion 52 elastically abuts against the second sliding shaft 422, and the second bending portion 531 of the second elastic portion 53 elastically abuts against the third sliding shaft 423. In this way, the second elastic member 5, with the cooperation of the arc-shaped portion 51, the first bending portion 521 of the first elastic portion 52 and the second bending portion 531 of the second elastic portion 53, enables the rotating base 1 of the hinge module 100 to drive the first connecting member 2 to rotate around the second rotating shaft 41 at different angles.

[0099] Understandably, the first elastic part 52 and the second elastic part 53 are connected to both ends of the arc-shaped part 51. Optionally, the material of the second elastic member 5 can be a metal material, such as stainless steel, which includes materials such as titanium alloy, nickel-titanium alloy, and beryllium copper; or, the material of the second elastic member 5 can also be a non-metallic material, such as elastic plastic or carbon fiber, etc., which is not limited here.

[0100] In this embodiment, the first elastic portion 52, the arc-shaped portion 51, and the second elastic portion 53 of the second elastic member 5 are integrally formed. The first elastic portion 52, the arc-shaped portion 51, and the second elastic portion 53 of the second elastic member 5 generally enclose and form a V-shaped structure.

[0101] To further limit the first elastic portion 52 and the second elastic portion 53 of the second elastic member 5, and to prevent the second elastic member 5 from shifting due to deformation during the rotation of the first connecting member 2 around the second rotating shaft 41 driven by the rotating base 1, in one embodiment, the outer wall of the rotating cylinder 125 is provided with a limiting protrusion 126 located between two adjacent sliding holes 122, and the bottom plate 12 is provided with a fixing protrusion 127 corresponding to the limiting protrusion 126. The limiting protrusion 126 and the fixing protrusion 127 abut against each other and cooperate with the bottom plate 12 to form a limiting space 128, in which the first elastic portion 52 and the second elastic portion 53 are respectively limited in the limiting space 128.

[0102] In this embodiment, as Figure 2 , Figure 3 , Figure 11 and Figure 12 As shown, by providing a limiting protrusion 126 and a fixing protrusion 127 on the outer wall of the rotating cylinder 125 and the bottom plate 12 of the rotating base 1 respectively, the limiting protrusion 126 and the fixing protrusion 127 abut against each other and cooperate with the bottom plate 12 to form a limiting space 128. The limiting space 128 is located between two adjacent sliding holes 122, thereby facilitating the use of the limiting space 128 to limit the first elastic part 52 and the second elastic part 53.

[0103] In one embodiment, the arcuate portion 51 forms an arcuate groove 511 on the side facing away from the rotating cylinder 125, the first bend portion 521 forms a first limiting groove 522 and a first limiting opening 523 that are connected, and the second bend portion 531 forms a second limiting groove 532 and a second limiting opening 533 that are connected; wherein, the hinge module 100 has an initial position, a first position and a second position in which the rotating base 1 drives the first connecting member 2 to rotate relative to the second connecting member 4 around the second rotating shaft 41; in the initial position, the first sliding shaft 421 is located in the arcuate groove 511 and the second sliding shaft 422 is located in the first limiting groove. At the junction of 522 and the first limiting port 523, the third sliding shaft 423 is located at the junction of the second limiting groove 532 and the second limiting port 533; in the first position, the first sliding shaft 421 slides to the junction of the arc-shaped part 51 and the first elastic part 52, and the second sliding shaft 422 is located in the first limiting groove 522, and the third sliding shaft 423 is located at the second limiting port 533; in the second position, the first sliding shaft 421 slides to the junction of the arc-shaped part 51 and the second elastic part 53, and the second sliding shaft 422 is located at the first limiting port 523, and the third sliding shaft 423 is located in the second limiting groove 532.

[0104] In this embodiment, as Figure 2 , Figure 7 , Figure 11 and Figure 12As shown, by providing an arc-shaped groove 511 on the arc-shaped portion 51, and providing a first limiting groove 522 and a first limiting opening 523 on the first bending portion 521, and providing a second limiting groove 532 and a second limiting opening 533 on the second bending portion 531, the limiting structure at the connection between the first limiting groove 522 and the first limiting opening 523 is used to achieve adjustment of different gears.

[0105] Understandably, the first limiting opening 523 formed by the first bending portion 521 gradually increases in size from the connection point between the first limiting groove 522 and the first limiting opening 523 to a point away from the connection point, that is, the first limiting opening 523 is flared. This facilitates the cooperation between the first limiting opening 523 and the second sliding shaft 422, and compresses the second sliding shaft 422 into the first limiting groove 522 from the connection point between the first limiting groove 522 and the first limiting opening 523. Similarly, the second limiting opening 533 formed by the second bending portion 531 gradually increases in size from the connection point between the second limiting groove 532 and the second limiting opening 533 to a point away from the connection point, that is, the second limiting opening 533 is flared. This facilitates the cooperation between the second limiting opening 533 and the third sliding shaft 423, and compresses the third sliding shaft 423 into the second limiting groove 532 from the connection point between the second limiting groove 532 and the second limiting opening 533.

[0106] Optionally, the shape and contour of the first limiting groove 522 are similar to those of the second sliding shaft 422. The shape and contour of the second limiting groove 532 are similar to those of the third sliding shaft 423.

[0107] Understandably, the rotating base 1 drives the first connecting member 2 to rotate relative to the second connecting member 4 around the second rotating shaft 41, so that the first connecting member 2 and the rotating base 1 have an initial position, a first position, and a second position. In this embodiment, in the initial position, the first sliding shaft 421 is located in the arc-shaped groove 511, and the second sliding shaft 422 is located at the connection between the first limiting groove 522 and the first limiting opening 523, and the third sliding shaft 423 is located at the connection between the second limiting groove 532 and the second limiting opening 533; in the first position, the first sliding shaft 421 slides to the connection between the arc-shaped part 51 and the first elastic part 52, and the second sliding shaft 422 is located in the first limiting groove 522, and the third sliding shaft 423 is located at the second limiting opening 533; in the second position, the first sliding shaft 421 slides to the connection between the arc-shaped part 51 and the second elastic part 53, and the second sliding shaft 422 is located at the first limiting opening 523, and the third sliding shaft 423 is located in the second limiting groove 532.

[0108] Optionally, the arc-shaped groove 511 has a semi-circular groove structure. The connection between the arc-shaped portion 51 and the first elastic portion 52 and the second elastic portion 53 forms two limiting points on both sides of the arc-shaped groove 511. The first limiting groove 522 formed by the first bending portion 521 and the first limiting opening 523 communicate at the first limiting point, and the second limiting groove 532 formed by the second bending portion 531 and the second limiting opening 533 communicate at the second limiting point. Understandably, when the first connector 2 and the rotating base 1 of the hinge module 100 are in their initial positions, the first sliding shaft 421 is located within the arc-shaped groove 511, the second sliding shaft 422 is located at the first limit position, and the third sliding shaft 423 is located at the second limit position. When the rotating base 1 drives the first connector 2 to rotate relative to the second connector 4 around the second rotating shaft 41, causing the first connector 2 and the rotating base 1 of the hinge module 100 to move from their initial positions to the first position, the first sliding shaft 421 located within the arc-shaped groove 511 moves to the limit position of the arc-shaped groove 511 near the second elastic part 53. At this time, the second sliding shaft 422 is located in the first limiting groove 522, and the third sliding shaft 423 is located at the second limiting opening 533. When the rotating base 1 drives the first connecting member 2 to rotate around the second rotating shaft 41 relative to the second connecting member 4, causing the first connecting member 2 and the rotating base 1 of the hinge module 100 to move from the initial position to the second position, the first sliding shaft 421 located in the arc-shaped groove 511 moves to the limiting point of the arc-shaped groove 511 near the first elastic part 52. At this time, the second sliding shaft 422 is located at the first limiting opening 523, and the third sliding shaft 423 is located in the second limiting groove 532.

[0109] It should be noted that when the hinge module 100 is in the open or outward-folded state, the first connecting member 2 of the hinge module 100 has an initial position, a first position, and a second position where the rotating base 1 drives the first connecting member 2 to rotate relative to the second connecting member 4 around the second rotating axis 41. When the hinge module 100 is applied to the eyeglasses 800, when the eyeglasses 800 is in the open or outward-folded state, the temples 820 of the eyeglasses 800 have an initial position, a first position, and a second position where the rotating base 1 drives the first connecting member 2 and the temples 820 to rotate relative to the frame 810 around the second rotating axis 41. When the temples 820 are in the initial position, the first sliding axis 421 is located within the arc-shaped groove 511, the second sliding axis 422 is located at the first limit position, and the third sliding axis 423 is located at the second limit position. When the temple 820 rotates relative to the frame 810 around the second pivot 41 from the initial position to the first position, the first sliding shaft 421 located in the arc-shaped groove 511 moves to the limiting point of the arc-shaped groove 511 near the second elastic part 53. At this time, the second sliding shaft 422 is located in the first limiting groove 522, and the third sliding shaft 423 is located at the second limiting opening 533. When the temple 820 rotates relative to the frame 810 around the second pivot 41 from the initial position to the second position, the first sliding shaft 421 located in the arc-shaped groove 511 moves to the limiting point of the arc-shaped groove 511 near the first elastic part 52. At this time, the second sliding shaft 422 is located at the first limiting opening 523, and the third sliding shaft 423 is located in the second limiting groove 532.

[0110] Understandable, such as Figure 13 As shown, in the first position, the temple 820 is above the initial position, and in the second position, the temple 820 is below the initial position.

[0111] In one embodiment, the second connecting member 4 includes a connecting plate 43 and a second rotating shaft 41 and a sliding shaft 42 protruding from the connecting plate 43. The second rotating shaft 41 is also provided with a fixing hole 411. The second connecting member 4 also includes a fixing member 44. One end of the fixing member 44 forms a limiting platform 441. The second rotating shaft 41 is rotatably inserted into the second rotating hole 121 and the rotating cylinder 125 so that the connecting plate 43 abuts against the side of the bottom plate 12 facing away from the side plate 13, and one end of the fixing member 44 is provided in the fixing hole 411 so that the limiting platform 441 and the rotating cylinder 125 are movably abutted.

[0112] In this embodiment, as Figure 2 , Figure 6 , Figures 10 to 12As shown, the connecting plate 43 of the second connector 4 is used to set the second rotating shaft 41 and the sliding shaft 42. By providing a fixing hole 411 in the second rotating shaft 41, when the second rotating shaft 41 rotates through the second rotating hole 121 and the sliding shaft 42 passes through the sliding hole 122, the connecting plate 43 and the bottom plate 12 of the rotating base 1 are limited and abutted. By providing one end of the fixing member 44 in the fixing hole 411, the limiting platform 441 is movable and abutted against the rotating cylinder 125 of the rotating base 1. In this way, the installation and rotational connection of the second connector 4 and the rotating base 1 can be realized.

[0113] Understandably, in order to connect the second connector 4 of the hinge module 100 to the frame 810, the second connector 4 is also provided with a fastening hole 431, through which a fastener 830 passes and is connected to the frame 810.

[0114] In this embodiment, as Figure 2 , Figure 6 , Figures 10 to 12 As shown, the connecting plate 43 of the second connector 4 is also provided with a fastening hole 431. The connecting plate 43 is inserted into the fastening hole 431 by a fastener 830 and connected to the frame 810. It is understood that the fastener 830 can be a screw or a pin.

[0115] To facilitate the installation, fixing and concealment of the hinge module 100, the frame 810 is also provided with a groove corresponding to the connecting plate 43 of the second connector 4. Thus, when the second connector 4 is connected to the frame 810, the connecting plate 43 is accommodated and limited within the groove, which is not limited here.

[0116] In one embodiment, the first elastic member 3 includes a main body 31 and a damping arm 32. One end of the main body 31 is housed in the receiving groove 11, and the other end of the main body 31 forms an outwardly folded elastic piece 311. The outwardly folded elastic piece 311 elastically abuts against the first connecting member 2. The main body 31 is also provided with an elastic through hole 312. One end of the damping arm 32 is connected to the inner wall of the elastic through hole 312, and the other end of the damping arm 32 extends along the elastic through hole 312 and bends to form a damping groove 321.

[0117] In this embodiment, the first elastic element 3 can be selected as a spring sheet or an elastic plate structure. The material of the first elastic element 3 can be stainless steel or carbon fiber. Optionally, when the material of the first elastic element 3 is stainless steel, the stainless steel material includes one of titanium alloy, nickel-titanium alloy, and beryllium copper. It can be understood that by providing an elastic through hole 312 in the main body 31 of the first elastic element 3, one end of the damping arm 32 is connected to the inner wall of the elastic through hole 312, and the other end of the damping arm 32 extends along the elastic through hole 312 and bends to form a damping groove 321, thereby improving the elastic performance of the damping arm 32.

[0118] Understandably, the main body 31 of the first elastic element 3 and the damping arm 32 are integrally formed, which improves the connection stability and structural strength between the damping arm 32 and the main body 31. In this embodiment, the inner wall of the damping groove 321 abuts against the outer wall of the first rotating shaft 24, so that frictional damping is formed when the first rotating shaft 24 rotates relative to the damping groove 321, so that the movement of the first rotating shaft 24 has a damped folding feel of the hinge movement, thereby realizing the folding of the temple 820 and making the folding have a damped feel.

[0119] Optionally, the distance from the end of the damping support arm 32 bent to form the damping groove 321 to the damping support arm 32 is defined as the opening width of the damping groove 321, and the opening width is less than or equal to 1 / 3 of the circumference of the first rotating shaft 24. It is understandable that by setting the damping groove 321 of the damping support arm 32 to a semi-open structure, that is, the damping groove 321 partially wraps around the outer wall of the first rotating shaft 24, it is convenient to install the first rotating shaft 24, and it also ensures that the damping groove 321 has good damping effect and damping feel.

[0120] Understandably, the cross section of the first rotating shaft 24 in the direction perpendicular to the axial direction of the first rotating shaft 24 may be circular, and the cross section of the damping groove 321 in the direction perpendicular to the axial direction of the first rotating shaft 24 may be arc-shaped, and the circumference of the arc-shaped inner wall of the damping groove is greater than or equal to 2 / 3 of the circumference of the first rotating shaft 24.

[0121] In this embodiment, an outward-folding spring 311 is formed at one end of the main body 31. The outward-folding spring 311 elastically abuts against the first connecting member 2. Thus, when the glasses 800 is in the outward-folding state, and the temple 820 drives the first connecting member 2 to rotate outward relative to the frame 810 around the first pivot 24, the first connecting member 2 drives the outward-folding spring 311 of the first elastic member 3 to elastically deform, thereby generating a torque for the first connecting member 2 to rotate inward, thus providing a holding force. When the outward-folding force is removed, the elastically deformed outward-folding spring 311 will push the first connecting member 2 to drive the temple 820 back to the original state of the outward-folding spring 311, thereby realizing that after the outward-folding force is removed, the temple 820 can automatically spring back to the original position.

[0122] Understandably, the first elastic element 3 can be selected as a spring sheet structure, which has good elasticity. Optionally, the elastic modulus of the first elastic element 3 is 50Gpa to 400Gpa, that is, the elastic modulus of the first elastic element 3 is 50Gpa, 100Gpa, 150Gpa, 200Gpa, 250Gpa, 300Gpa, 350Gpa, 400Gpa, etc., which are not limited here.

[0123] To facilitate the clamping force provided by the outward-folding spring 311 when it folds the first connecting member 2 outward, and to ensure automatic rebound after the outward-folding force is removed, the length of the outward-folding spring 311 in this embodiment can be selected from 5mm to 30mm. Optionally, the length of the outward-folding spring 311 can be 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, etc., and is not limited here. Optionally, the thickness of the outward-folding spring 311 can be 0.3mm to 1.5mm, that is, the thickness of the outward-folding spring 311 can be 0.3mm, 0.5mm, 0.8mm, 1mm, 1.3mm, 1.5mm, etc., and is not limited here. It can be understood that this setting can ensure that the first elastic member 3 has good elasticity.

[0124] In one embodiment, a fixing post 123 protrudes from the bottom wall of the receiving groove 11. The fixing post 123 is located between the first rotating hole 131 and the second rotating hole 121, and the main body 31 is fixed to the fixing post 123 by fasteners.

[0125] In this embodiment, as Figure 2 , Figure 3 , Figures 10 to 12 As shown, a fixing post 123 is provided in the receiving groove 11 of the rotating base 1, and a through hole is provided on the first elastic member 3 corresponding to the fixing post 123. Fasteners are then screwed or inserted through the through hole to the fixing post 123, thus fixing the first elastic member 3 to the rotating base 1. Simultaneously, the fixing post 123 provides support for the first elastic member 3. Optionally, the fixing post 123 is located between the first rotating hole 131 and the second rotating hole 121.

[0126] Understandably, the fixing post 123 may optionally be a threaded post, and the fastener may be a screw or pin, etc.

[0127] In one embodiment, one of the groove wall of the receiving groove 11 and the main body 31 is provided with a latching protrusion 313 and the other of the receiving groove 124, and the latching protrusion 313 is limited to the latching groove 124.

[0128] In this embodiment, as Figure 2 , Figure 3 , Figure 5 , Figure 11 and Figure 12 As shown, by providing a locking protrusion 313 in one of the rotating base 1 and the first elastic member 3, and a locking groove 124 in the other, with the locking protrusion 313 confined within the locking groove 124, the positioning, installation, and locking of the first elastic member 3 are further achieved. It can be understood that the locking protrusion 313 is located on the first elastic member 3, and the locking groove 124 is located on the rotating base 1. Thus, with the locking protrusion 313 confined within the locking groove 124, both positioning and locking can be achieved, and the main body 31 of the first elastic member 3 can be supported by the locking protrusion 313 to ensure the deformation capability of the first elastic member 3.

[0129] In one embodiment, there are two first rotating holes 131, which are coaxially arranged and located on opposite sides of the receiving groove 11; the first connecting member 2 includes a first connecting part 21 and two rotating arms 22 disposed at both ends of the first connecting part 21, the two rotating arms 22 and the first connecting part 21 enclose to form a relief groove 23, and each rotating arm 22 has a mounting hole 221 at one end away from the first connecting part 21; wherein, the first rotating shaft 24 is sequentially inserted into the mounting hole 221, the first rotating hole 131 and the damping groove 321, and both ends of the first rotating shaft 24 are fixed in the two mounting holes 221 so that part of the rotating base 1 is accommodated in the relief groove 23, and the end of the first elastic member 3 away from the second rotating hole 121 elastically abuts against the first connecting part 21.

[0130] In this embodiment, as Figures 1 to 3 , Figures 11 to 12 As shown, the base plate 12 of the rotating base 1 may optionally be rectangular, and the portions of the side plates 13 of the rotating base 1 located on the two long axis sides of the base plate 12 are parallel and opposite to each other. That is, each side plate 13 located on the two long axis sides of the base plate 12 is provided with a first rotating hole 131, and the two first rotating holes 131 are coaxially arranged. Optionally, the line connecting the two first rotating holes 131 is perpendicular to the axis of the second rotating shaft 41.

[0131] Understandable, such as Figure 1 , Figure 2 and Figure 4 As shown, by configuring the first connector 2 as a first connecting portion 21 and two rotating arms 22 at both ends of the first connecting portion 21, the two rotating arms 22 and the first connecting portion 21 enclose a U-shaped clearance groove 23. A mounting hole 221 is provided at the end of the rotating arm 22 away from the first connecting portion 21. Thus, the first connecting portion 21 of the first connector 2 is connected to the temple 820. A first rotating shaft 44 is sequentially inserted into the mounting hole 221, the first rotating hole 131, and the damping groove 321, with both ends of the first rotating shaft 24 fixed within the two mounting holes 221, allowing part of the rotating base 1 to be accommodated within the clearance groove 23, thereby achieving a rotatable connection between the first connector 2 and the rotating base 1. Optionally, the first connector 2 and the temple 820 can be connected and fixed by welding, bonding, or using screws, pins, etc.

[0132] In one embodiment, the first rotating shaft 24 includes a rotating shaft portion 241 and mounting portions 242 connected to both ends of the rotating shaft portion 241. The rotating shaft portion 241 passes through the first rotating hole 131 and the damping groove 321 in sequence. Each mounting portion 242 is confined within a mounting hole 221. The mounting hole 221 has at least one mounting surface 222. The mounting portion 242 has a limiting surface 243 that cooperates with the mounting surface 222.

[0133] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, by providing limiting planes 243 at both ends of the first rotating shaft 24 and providing a mounting plane 222 in the mounting hole 221, when the mounting part 242 of the first rotating shaft 24 is limited within the mounting hole 221, the limiting planes 243 and the mounting plane 222 are used to limit and cooperate, thereby ensuring that the first connecting member 2 rotates synchronously with the first rotating shaft 24, that is, the first connecting member 2 drives the first rotating shaft 24 to rotate relative to the first rotating hole 131 and the damping groove 321.

[0134] Understandably, the cross-section of the rotating shaft portion 241 of the first rotating shaft 24 may optionally be circular. Optionally, the mounting hole 221 is a polygonal hole, and the first rotating hole 131 is a circular hole. In this embodiment, the first rotating shaft 24 is a pin with a different cross-section, and both ends of the first rotating shaft 24 are flat shafts, used to fix together with the mounting hole 221 of the first connector 2, for example, by interference fit, spot welding, bonding, etc. The first rotating shaft 24 and the first rotating hole 131 of the rotating base 1 are fitted with a rotatable circular hole cylinder to form a rotation center for mutual rotation between the two.

[0135] In one implementation, such as Figure 2 , Figure 4 As shown, the first connecting part 21 is recessed to form a relief groove 211 that connects to the relief groove 23. A support platform 212 is provided on the side of the relief groove 211 adjacent to the relief groove 23. The end of the first elastic member 3 away from the second rotating hole 121 extends into the relief groove 211 and is elastically supported on the support platform 212.

[0136] Understandably, by providing a clearance groove 211 in the first connecting part 21 of the first connector 2, on the one hand, the clearance groove 211 provides clearance space for the outward-turning spring piece 311 of the first elastic member 3, and on the other hand, the clearance groove 211 can also provide a limiting space for the outward-turning spring piece 311.

[0137] In one embodiment, the first connecting member 2 further includes a limiting part 25, the two ends of which are respectively connected to the ends of the two rotating arms 22 away from the first connecting part 21, and the limiting part 25 is located on the side of the first elastic member 3 facing away from the receiving groove 11.

[0138] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, by providing a limiting part 25 on the first connecting member 2, the two ends of the limiting part 25 are respectively connected to the ends of the two rotating arms 22 away from the first connecting part 21, so that the limiting part 25 can achieve the limiting function when the first connecting member 2 rotates around the first rotating shaft 24 relative to the rotating base 1.

[0139] Understandably, the hinge module 100 has a folded state, an open state, and an outward-folding state in which the first connecting member 2 rotates relative to the rotating base 1 around the first pivot 24. In the folded state, the rotating arm 22 is perpendicular to the base plate 12, the first connecting part 21 is away from the outward-folding spring 311, and the limiting part 25 is close to the outward-folding spring 311. In the open state, the rotating arm 22 is parallel to the base plate 12, and the outward-folding spring 311 abuts against the support platform 212, and the limiting part 25 is located on the side of the side plate 13 away from the base plate 12. In the outward-folding state, the rotating arm 22 is at an angle to the base plate 12, and the first connecting part 21 causes the outward-folding spring 311 to deform, and the limiting part 25 moves towards the side plate 13 in a direction away from the outward-folding spring 311.

[0140] It should be noted that when the hinge module 100 is applied to the glasses 800, the glasses 800 has a folded state, an open state, and an outward-folding state in which the first connecting member 2 drives the temple 820 to rotate around the first pivot 24 relative to the rotating base 1 and the frame 810. In the folded state, the temple 820 is close to the frame 810, and the first connecting part 21 is away from the first elastic member 3, while the limiting part 25 is close to the outward-folding spring 311. In the open state, the temple 820 is away from the frame 810 and is perpendicular to the frame 810. The first connecting part 21 abuts against the outward-folding spring 311, and the limiting part 25 is away from the outward-folding spring 311. In the outward-folding state, the temple 820 is set at an obtuse angle to the frame 810, and the first connecting part 21 causes the outward-folding spring 311 to deform.

[0141] Understandably, when the glasses 800 are in the folded state, the rotating arm 22 of the first connector 2 is approximately perpendicular to the base plate 12 of the rotating base 1, and the limiting part 25 is close to the outward-folding spring 311. When the glasses 800 are in the open state, the limiting part 25 is located on the side of the side plate 13 of the rotating base 1 away from the base plate 12. When the glasses 800 are in the outward-folding state, when the first connecting part 21 of the first connector 2 causes the outward-folding spring 311 to deform to its maximum deformation, the limiting part 25 abuts against the side plate 13 of the rotating base 1 to prevent the temples 820 from excessively folding outward.

[0142] In one embodiment, the hinge module 100 further includes a protective plate 6 and a housing 7. The protective plate 6 is housed in the receiving groove 11 and connected to the side of the first elastic member 3 facing away from the bottom wall of the receiving groove 11. The protective plate 6 is provided with a wire passage groove 61 on the side facing away from the first elastic member 3. The housing 7 covers the opening of the receiving groove 11 and cooperates with the wire passage groove 61 to form a wiring channel 71.

[0143] In this embodiment, as Figure 1 , Figure 2 , Figure 9 and Figure 10As shown, by setting up a protective plate 6 and a housing 7, the protective plate 6 provides wiring or mounting space for the flexible circuit board of the optical system connecting the glasses 800. It can be understood that the protective plate 6 is housed in the receiving groove 11, and the protective plate 6 and the first elastic member 3 are fixed to the fixing post 123 of the rotating base 1 in sequence by fasteners, thereby realizing the installation and fixation of the protective plate 6.

[0144] Understandably, by providing a wire routing groove 61 on the side of the protective plate 6 facing away from the first elastic member 3, it is convenient to use the wire routing groove 61 to realize the installation of wires or flexible circuit boards. In this embodiment, by providing a housing 7, on the one hand, it is to protect the cables or flexible circuit boards in the wire routing groove 61, and on the other hand, it is to improve the appearance.

[0145] Optionally, the housing 7 is detachably mounted on the opening of the receiving groove 11 and cooperates with the wire guide 61 to form a wiring channel 71. It is understood that by adopting a detachable connection between the housing 7 and the rotating base 1, the housing 7 can be easily removed at any time, making it convenient to install cables or flexible circuit boards in the wire guide 61.

[0146] The hinge module 100 of this invention mainly relates to a rotation axis with two degrees of freedom. When the hinge module 100 is applied to eyeglasses 100, for example... Figure 10 The first rotating shaft 24 (shaft A) shown and as... Figure 11 and Figure 12 The second pivot 41 (axis B) shown is used to realize the folding, unfolding, and outward-folding functions of the temples 820. Understandably, the folding function allows for the folding and storage of the temples 820, while the outward-folding function allows for comfort adjustment for users with different head widths. Axis B is used to realize the lateral adjustment function of the temples 820, and axis B has three adjustment levels to meet the comfort needs of users with different head shapes and nose-ear ratios.

[0147] Understandable, such as Figure 1 and Figure 2 The diagram shows the composition of the hinge module 100. The first connector 2, the rotating base 1, and the first elastic element 3 can be pre-assembled together as a single module via the first rotating shaft 24. Then, the second connector 4, the second elastic element 5, the protective plate 6, and the outer shell 7 are assembled sequentially.

[0148] In this embodiment, the first connecting member 2, the rotating base 1, and the first elastic member 3 are assembled into a modular structure via the first rotating shaft 24. The hinge module 100 passes through the second rotating hole 121 of the rotating base 1 via the second rotating shaft 41 of the second connecting member 4, and is connected and fixed to the fixing member 44. The second elastic member 5 is elastically limited between the rotating cylinder 125 and the sliding shaft 42 of the rotating base 1. The first connecting member 2 is rigidly connected to the temple 820 via screws, adhesives, or other fixing methods. The second connecting member 4 is connected to the frame 810. The hinge module 100 is used to realize the axis A movement of the temple 820 and provide the outward rotation force. After the hinge module 100 is assembled with the frame 810 through the cooperation of the second connecting member 4 and the second elastic member 5, it is used to realize the lateral movement of the temple 820 and provide the force (i.e., axis B). Figure 10 and Figure 14 As shown, axis A is used to achieve folding and outward rotational movements; as Figure 11 , Figure 12 and Figure 13 As shown, axis B is used to realize the side axis adjustment function of temple 820.

[0149] Understandably, the temple 820 of the eyeglasses 800 and the frame 810 are hinged together to achieve outward folding and damping. When the temple 820 is rotated, it will drive the first connecting piece 2 to rotate. The rotating base 1 is fixed to the frame 810 through the second connecting piece 4. The first elastic member 3 is a metal plate with good elasticity. The outward folding spring 311 on the first elastic member 3 is used to provide clamping force when folding outward and automatic rebound after the outward folding force is removed. The damping groove 321 of the damping support arm 32 of the first elastic member 3 is used to provide damping force during the rotation of the temple 820, so that there is a certain damping feeling during the movement. The first rotating shaft 24 is a pin with different cross sections, of which both ends are flat shafts, used to rigidly fix it together with the first connecting piece 2, for example, by interference fit, spot welding, bonding, etc. The fixation of the first rotating shaft 24 and the rotating base 1 is a rotatable round hole cylindrical fit to form a rotating central shaft A for mutual rotation between the two. Therefore, when the temple 820 is folded, the temple 820 will drive the first connecting piece 2 inward, and form a folding motion with the rotating base 1 through the first rotating shaft 24. The first rotating shaft 24 and the first connecting piece 2 rotate together. The rotation of the first rotating shaft 24 will form frictional damping with the damping groove 321 of the first elastic member 3, so that the hinge movement has a damped folding feel during the movement, thereby realizing the folding of the temple 820 and making the folding have a damped feel.

[0150] When the temple 820 is turned outwards, it accommodates users with different head widths. The temple 820 will cause the first connecting piece 2 to rotate outwards. The rotating first connecting piece 2 will cause the outward-turning spring piece 311 on the first elastic member 3 to deform elastically, thereby generating a torque that pushes the first connecting piece 2 to rotate inwards, thus providing a supporting force. When the outward-turning force is removed, the elastically deformed outward-turning spring piece 311 will push the first connecting piece 2 to drive the temple 820 back to the original state of the spring piece, thereby realizing that after the outward-turning force is removed, the temple 820 can automatically spring back to the original position.

[0151] Understandably, the temples 820 and frame 810 of the glasses 800 can also achieve a lateral axis adjustment structure to adjust the angle between the temples 820 and frame 810, accommodating users with different head shapes. The hinge module 100 first passes through the positioning groove of the frame 810, and then the fastener 830 positions and restricts the second connector 4 to the corresponding groove of the frame 810, fixing it in place. Since the second pivot 41 of the second connector 4 in the hinge module 100 and the second pivot hole 121 in the rotating base 1 cooperate to form a rotating axis, constituting a lateral rotation center axis B, when the temples 820 are rotated vertically, the temples 820 drive the hinge module 100 to rotate along the rotation center axis B. When the first sliding shaft 421 engages with the arc-shaped groove 511, the cylinder of the first sliding shaft 421 makes interference contact with the elastic groove of the arc-shaped groove 511, maintaining the temples 820 in their initial position. Position; When the temple 820 is rotated downwards, the cylinder of the first sliding shaft 421 disengages from the arc-shaped groove 511. When it continues to rotate to a predetermined angle, such as 10 degrees, the cylinder of the third sliding shaft 423 will elastically press into the groove of the second limiting groove 532. The second limiting groove 532 restricts the third sliding shaft 423, and the temple 820 remains in the second position state of rotating downwards by 10 degrees, thus completing the lateral downward posture adjustment of the temple 820. Similarly, the second sliding shaft 422 and the first limiting groove 522 complete the upward angle adjustment, so that the temple 820 remains in the first position state of upward rotation, completing the angle adjustment between the temple 820 and the frame 810. The schematic diagram after rotation is shown below. Figure 12 and Figure 13 As shown.

[0152] The sliding shaft 42 can slide within the corresponding sliding hole 122 on the rotating base 1, simultaneously enhancing the resistance to deformation when the temple 820 is twisted, and preventing over-bending failure. The second elastic element 5 can be made of stainless steel, including materials such as titanium alloy, nickel-titanium alloy, and beryllium copper; or, it can be made of composite materials such as carbon fiber. Optionally, the elastic modulus of the second elastic element 5 is between 50 GPa and 400 GPa. Understandably, the shape of the second elastic element 5 can be as follows... Figure 7The fastener 830 can be one or more, and there is no limitation on the number of fasteners 830.

[0153] like Figures 8 to 14 As shown, the present invention also proposes a pair of eyeglasses 800, which includes a frame 810, temples 820, and the aforementioned hinge module 100. The specific structure of the hinge module 100 is as described in the foregoing embodiments. Since the eyeglasses 800 adopts all the technical solutions of all the foregoing embodiments, it has at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be described in detail here.

[0154] Understandably, the second connector 4 of the hinge module 100 is connected to the frame 810, and the first connector 2 of the hinge module 100 is connected to the temple 820. In this embodiment, the glasses 800 can be ordinary glasses such as myopia glasses, presbyopia glasses, astigmatism glasses, sun protection glasses, and decorative glasses. The glasses 800 can also be smart glasses, such as virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR) glasses, etc., without limitation.

[0155] It should be noted that the frame 810 of the glasses 800 has mounting holes corresponding to the user's two eyes. These two mounting holes can be used to mount different lenses or intelligent optical systems, etc., which are not limited here. For the convenience of the user, the frame 810 also has a nose pad structure between the two mounting holes for abutting against the user's nose bridge, etc., which are not limited here.

[0156] To facilitate wearing the glasses 800, the frame 810 is typically rotatably connected to two symmetrically arranged temples 820, allowing the user to wear the glasses via the nose pads and temples 820. Of course, in other embodiments, the frame 810 can also be connected to a headband structure, forming a ring-shaped wearing space with the frame 810. This is particularly relevant for smart glasses devices, where the frame 810 is relatively heavy due to the optical system mounted on it. Therefore, a headband or headband structure is designed to facilitate wearing and prevent the frame 810 from falling off due to its weight; this is not a limitation here.

[0157] In this embodiment, the eyeglasses 800 are described using the structure of a frame 810 and two temples 820 as an example. To facilitate the connection between the frame 810 and the two temples 820, connecting portions or mounting portions are provided at both ends of the frame 810. It can be understood that the two connecting portions or mounting portions at both ends of the frame 810 are set at a certain angle to the plane containing the two mounting holes of the frame 810, that is, the two connecting portions or mounting portions are generally formed by extending from both ends of the frame 810 toward the user's ears.

[0158] It should be noted that, in order to avoid the two connecting parts or mounting parts at both ends of the frame 810 affecting the user's wearing experience, the extension length of the two connecting parts or mounting parts is relatively short. The extension length of the two connecting parts or mounting parts can refer to existing technology and is not limited here.

[0159] In this embodiment, as Figure 8 and Figure 9 As shown, the two connecting or mounting parts at both ends of the frame 810 are respectively provided with mounting grooves. The mounting grooves are used to accommodate and mount at least part of the hinge module 100, and the hinge module 100 is used to connect with the temple 820, so that the temple 820 is rotatably connected to the connecting or mounting parts at both ends of the frame 810 through the hinge module 100.

[0160] In this embodiment, the glasses 800 can also be an AR device. The glasses 800 also includes an optical system connected to the frame 810 of the glasses 800. It is understood that the glasses 800 includes a flexible circuit board, one end of which passes through the wiring channel 71 and is electrically connected to the optical system. The temple 820 of the glasses 800 has a mounting cavity or other structure for installing a power supply. The other end of the flexible circuit board is guided through the wiring channel 71 to the mounting cavity of the temple 820 and electrically connected to the power supply or other components; this is not limited here.

[0161] It is understandable that glasses 800 can be virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR) glasses, and no specific limitation is made here.

[0162] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
