[0002] This application relates to the field of eyewear technology, and in particular to an eyeglass and an AR device using the eyeglass. Background Technology

[0003] 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.

[0004] 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

[0031] And / or, the second connecting member includes a connecting plate and a second rotating shaft and a sliding shaft protruding from the connecting plate. The second rotating shaft is provided with a fixing hole. The second connecting member also includes a fixing member. One end of the fixing member forms a limiting platform. The second rotating shaft is sequentially rotated through the first through hole and the second rotating hole, so that the frame is clamped between the connecting plate and the rotating base. One end of the fixing member is provided in the fixing hole, so that the limiting platform and the rotating base can movably abut against each other.

[0032] In one embodiment, the first rotating hole includes two holes, which are coaxially arranged and located on opposite sides of the receiving groove;

[0033] 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. The first connecting part is connected to the temple.

[0034] 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.

[0035] In one embodiment, the first rotating shaft includes a rotating shaft portion and mounting portions connected to both ends of the rotating shaft portion. The rotating shaft portion passes through the first rotating hole and the damping groove in sequence. Each mounting portion is confined within a mounting hole. The mounting hole has at least one mounting plane, and the mounting portion has a limiting plane that mates with the mounting plane.

[0036] And / or, the mounting hole is a polygonal hole, and the first rotating hole is a circular hole;

[0037] And / or, the first connecting portion is recessed to form a relief groove that communicates with the relief groove, and a support platform is provided on one side of the relief groove adjacent to the relief groove. The end of the first elastic member away from the second rotating hole extends into the relief groove and is elastically supported on the support platform.

[0038] In one embodiment, the first connector further includes a limiting portion, the two ends of which are respectively connected to the ends of the two rotating arms away from the first connector, and the limiting portion is located on the side of the first elastic member facing away from the receiving groove. The first elastic member has an outwardly folded spring sheet that elastically abuts against the first connector.

[0039] The glasses have a folded state, an open state, and an outward-folding state in which the first connector drives the temples to rotate around the first pivot relative to the rotating base and the frame.

[0040] In the folded state, the temple is close to the frame, the first connecting portion is away from the first elastic member, and the limiting portion is close to the outward-folding spring.

[0041] In the open state, the temples are away from the frame and perpendicular to the frame, the first connecting part abuts against the outward-folding spring, and the limiting part is away from the outward-folding spring;

[0042] In the outward-folding state, the temple and the frame are set at an obtuse angle, and the first connecting part causes the outward-folding spring to deform.

[0043] In one embodiment, the glasses further include a protective plate and a housing. The protective plate is housed in the receiving groove and connected to the side of the first elastic member facing away from the bottom wall of the receiving groove. The side of the protective plate facing away from the first elastic member is provided with a wire passage groove. The housing covers the opening of the receiving groove and cooperates with the wire passage groove to form a wire routing channel.

[0044] This application also proposes an AR device, which includes an optical system and the glasses described above, wherein the optical system is connected to the frame of the glasses.

[0045] The eyeglasses of this application feature a mounting groove on the frame, along with a first through hole and a second through hole connecting the mounting groove. This allows for convenient housing and positioning of a rotating base with a hinge structure via the mounting groove. The rotating base has a receiving groove, a first rotating hole, a second rotating hole, and a sliding hole connecting the receiving groove. The second rotating hole corresponds to the first through hole, and the sliding hole corresponds to the second through hole. One end of the first connector of the hinge structure is rotatably connected to the rotating base via a first rotating shaft engaging with the hole shaft of the first rotating hole. The other end of the first connector is connected to the temple. The second rotating shaft of the second connector of the hinge structure rotatably passes through the first through hole and the second rotating hole, while the sliding shaft movably passes through the second through hole and the sliding hole. This allows the temples and frame of the eyeglasses to be rotatably connected via the first connector, the rotating base, and the second connector of the hinge structure. The axial direction of the first rotating shaft is angled to the axial direction of the second rotating shaft, allowing the temples to rotate around the first connector. A pivot axis rotates relative to the rotating base and the frame, while the temples can also rotate relative to the frame via the rotating base around a second pivot 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 pivot axis, the other end of the first elastic element elastically abuts against the first connecting member. Thus, when the temples rotate relative to the rotating base and frame via the first connecting member around the first pivot axis, the first elastic element provides damping for the temples' rotation. A second elastic element is placed within the frame and elastically abuts against the rotating base, providing elastic limiting and damping functions for the rotation of the rotating base relative to the frame, thereby offering different rotation angles.

[0067] 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.

[0068] 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.

[0069] Based on the above concept and problems, this application proposes a pair of glasses 100. The glasses 100 can not only realize the functions of folding and storing the temples 2 relative to the frame 1, normal wearing, and outward turning, but also enable the temples 2 to rotate and adjust relative to the frame 1 in another direction, so that the glasses 100 can be worn by users with different head lengths, different head shapes, and different nose-ear distances, thereby improving the user's wearing comfort and versatility.

[0070] Referring to Figures 1 to 14, in this embodiment of the application, the eyeglasses 100 includes a frame 1, temples 2, and a hinge structure. The frame 1 has a mounting groove 11 and a first through hole 13 and a second through hole 14 communicating with the mounting groove 11. The hinge structure includes a rotating base 3, a first connector 4, a first elastic member 5, a second connector 6, and a second elastic member 7. One end of the rotating base 3 is movably accommodated in the mounting groove 11, and the rotating base 3 has a receiving groove 31 and a first rotating hole 331, a second rotating hole 321, and a sliding hole 322 communicating with the receiving groove 31. The second rotating hole 321 corresponds to the first through hole 13, and the sliding hole 322 corresponds to the second through hole 14. One end of the first connector 4 is connected to the hole shaft of the first rotating hole 331 via a first rotating shaft 44. The first connecting member 4 is rotatably connected to the rotating base 3. The other end of the first connecting member 4 is connected to the temple 2. One end of the first elastic member 5 is housed in the receiving groove 31 and is provided with a damping groove 521 that rotatably abuts against the first rotating shaft 44. The other end of the first elastic member 5 is elastically abutting against the first connecting member 4. The second connecting member 6 is provided with a second rotating shaft 61 and a sliding shaft 62 spaced apart. The second rotating shaft 61 is rotatably passed through the first through hole 13 and the second rotating hole 321 in sequence, so that the rotating base 3 is rotatably connected to the frame 1. The sliding shaft 62 is movably passed through the second through hole 14 and the sliding hole 322. The second elastic member 7 is provided in the frame 1 and elastically abuts against the rotating base 3. The axial direction of the first rotating shaft 44 is set at an angle to the axial direction of the second rotating shaft 61.

[0071] In this embodiment, the glasses 100 can be ordinary glasses such as myopia glasses, reading glasses, astigmatism glasses, sun protection glasses, and decorative glasses. The glasses 100 can also be smart glasses, such as virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR) glasses, etc., which are not limited here.

[0072] Understandably, the frame 1 of the glasses 100 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 is not limited here. For the convenience of the user, the frame 1 also has a nose pad structure between the two mounting holes for abutting against the user's nose bridge, etc., which is not limited here.

[0073] It should be noted that, to facilitate the user's wearing of the glasses 100, the frame 1 of the glasses 100 is typically rotatably connected to two symmetrically arranged temples 2, allowing the user to wear the glasses via the nose pads of the frame 1 and the two temples 2. Of course, in other embodiments, the frame 1 can also be connected to a headband structure, so that the headband structure and the frame 1 enclose a ring-shaped wearing space, etc. Especially for smart glasses devices, because the optical system is installed on the frame 1, the frame 1 is relatively heavy. To facilitate wearing and prevent the frame 1 from falling due to its weight, a headband structure or headband structure is designed, etc., which is not limited here.

[0074] In this embodiment, the eyeglasses 100 are described using the structure of the frame 1 and two temples 2 as an example. To facilitate the connection between the frame 1 and the two temples 2, connecting portions or mounting portions are provided at both ends of the frame 1. It can be understood that the two connecting portions or mounting portions at both ends of the frame 1 are set at a certain angle to the plane where the two mounting holes of the frame 1 are located, that is, the two connecting portions or mounting portions are generally formed by extending from both ends of the frame 1 toward the user's ears.

[0075] It should be noted that, in order to avoid the two connecting parts or mounting parts at both ends of the frame 1 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 the existing technology and is not limited here.

[0076] In this embodiment, as shown in Figures 2 and 3, the two connecting parts or mounting parts at both ends of the frame 1 are respectively provided with mounting grooves 11 and a first through hole 13 and a second through hole 14 communicating with the mounting grooves 11. The mounting grooves 11 are used to accommodate and install at least part of the hinge structure, and are connected to the temple 2 by means of the hinge structure, so that the temple 2 is rotatably connected to the connecting parts or mounting parts at both ends of the frame 1 through the hinge structure.

[0077] Understandably, by setting the hinge structure as a rotating base 3, a first connecting member 4, and a second connecting member 6, and by providing a receiving groove 31 and a first rotating hole 331, a second rotating hole 321, and a sliding hole 322 communicating with the receiving groove 31, one end of the first connecting member 4 is rotatably connected to the rotating base 3 via a first rotating shaft 44 that engages with the hole shaft of the first rotating hole 331, and the other end of the first connecting member 4 is connected to the temple 2. That is, the temple 2 is connected to the rotating base 3 via the first connecting member 4 and the first rotating shaft 44. The base 3 is fitted to achieve a rotatable connection, and one end of the rotating base 3 is movably accommodated in the mounting groove 11, so that the second rotating hole 321 corresponds to the first through hole 13 and the sliding hole 322 corresponds to the second through hole 14. In this way, the second rotating shaft 61 of the second connector 6 is rotatably inserted through the first through hole 13 and the second rotating hole 321 in sequence, and the sliding shaft 62 is movably inserted through the second through hole 14 and the sliding hole 322, so that the rotating base 3 is rotatably connected to the frame 1, thereby realizing the rotatable connection of the temple 2 to the frame 1 through the hinge structure.

[0078] It should be noted that, since the axial direction of the first rotating shaft 44 is set at an angle to the axial direction of the second rotating shaft 61, that is, the temple 2 rotates relative to the rotating base 3 and the frame 1 via the first connecting piece 4 about the axial direction of the first rotating shaft 44, and the temple 2 rotates relative to the frame 1 via the rotating base 3 about the axial direction of the second rotating shaft 61, the temple 2 can rotate with multiple degrees of freedom relative to the frame 1 in multiple axial directions. This makes the glasses 100 suitable for users with different head lengths, head shapes, and nose-ear distances, improving the user's wearing comfort and versatility.

[0079] In this embodiment, by housing one end of the first elastic member 5 within the receiving groove 31 and providing a damping groove 521 on the first elastic member 5 that rotatably abuts against the first rotating shaft 44, and by elastically abutting the other end of the first elastic member 5 against the first connecting member 4, the temple 2 rotates relative to the rotating base 3 and the frame 1 via the first connecting member 4 about the axial direction of the first rotating shaft 44. This allows the temple 2 to utilize the frictional damping generated by the first elastic member 5 during rotation, resulting in a damped folding feel during the movement of the temple 2, thus achieving the folding of the temple 2 and providing a damped folding feel and an outward clamping force. Simultaneously, by placing the second elastic member 7 within the frame 1 and elastically abutting against the rotating base 3, the second elastic member 7 provides resistance to deformation and prevents over-bending failure during the rotation of the temple 2 relative to the frame 1 via the rotating base 3 about the axial direction of the second rotating shaft 61.

[0080] The eyeglasses 100 of this application, by providing a mounting groove 11 and a first through hole 13 and a second through hole 14 communicating with the mounting groove 11, facilitates the use of the mounting groove 11 to conveniently accommodate and limit the rotating base 3 of the hinge structure. The rotating base 3 is provided with a receiving groove 31 and a first rotating hole 331, a second rotating hole 321 and a sliding hole 322 communicating with the receiving groove 31, such that the second rotating hole 321 corresponds to the first through hole 13 and the sliding hole 322 corresponds to the second through hole 14. In this way, one end of the first connecting member 4 of the hinge structure is connected to the first hinge through the first rotating shaft 44. The pivot hole 331 is rotatably connected to the rotating base 3, and the other end of the first connecting member 4 is connected to the temple 2. The second pivot 62 of the second connecting member 6, using a hinge structure, is rotatably inserted through the first through hole 23 and the second pivot hole 321. The sliding shaft 62 is movably inserted through the second through hole 24 and the sliding hole 322. Thus, the temple 2 and frame 1 of the eyeglasses 100 are rotatably connected through the first connecting member 4, the rotating base 3, and the second connecting member 6 of the hinge structure. The axial direction of the first pivot 44 is set at an angle to the axial direction of the second pivot 61. This allows the temple 2 to rotate relative to the rotating base 3 and the frame 1 via the first connecting member 4 about the first rotating axis 44. Simultaneously, the temple 2 can also rotate relative to the frame 1 via the rotating base 3 about the second rotating axis 61. That is, the temple 2 and the frame 1 can achieve multi-degree-of-freedom rotational hinge through the multi-axis rotation of the hinge structure, making the glasses 100 suitable for different head shapes of different users, such as users with different head lengths, different head shapes, and different nose-ear distances, thereby improving the user's wearing comfort and versatility. Furthermore, by placing one end of the first elastic member 5 within the receiving groove 31, and in the first... The elastic element 5 is provided with a damping groove 521 that rotates and abuts against the first rotating shaft 44, so that the other end of the first elastic element 5 elastically abuts against the first connecting member 4. Thus, when the temple 1 rotates relative to the rotating base 3 and the frame 1 via the first connecting member 4 around the first rotating shaft 44, the first elastic element 5 provides damping performance for the rotation of the temple 2. The second elastic element 7 is provided inside the frame 1 and elastically abuts against the rotating base 3. Thus, the second elastic element 7 provides elastic limiting function and damping function for the rotation of the rotating base 3 relative to the frame 1, thereby providing different rotation angles.

[0081] In this embodiment, the axial direction of the first rotating shaft 44 and the axial direction of the second rotating shaft 61 are optionally perpendicular. It can be understood that, with the user wearing glasses 100 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 44, and the axial direction of the second rotating shaft 61 are approximately perpendicular to each other in a three-dimensional coordinate structure. That is, the axial direction of the first rotating shaft 44 is approximately perpendicular to the light emission direction, and the axial direction of the second rotating shaft 61 is approximately perpendicular to the light emission direction.

[0082] It should be noted that, as shown in Figure 8, the glasses 100 has three states: a folded state, an open state, and an outward-folding state, in which the temples 2 rotate relative to the rotating base 3 and the frame 1 via the first connecting member 4 around the first rotating axis 44. Understandably, in the folded state, the temples 2 are close to the frame 1, meaning they are roughly parallel to the frame 1, making the glasses 100 easy to store. In the open state, the two temples 2 are roughly perpendicular to the frame 1, forming a U-shaped wearing cavity with the frame 1. This facilitates the contact between the temples 2 and the user's ears, and the nose pads of the frame 1 contact the user's nose bridge, thus enabling wearing. When the glasses 100 are in the outward-folded position, the two temples 2 are set at approximately an obtuse angle to the frame 1. At this time, the two temples 2 and the frame 1 roughly enclose to form a wide-mouthed U-shaped wearing cavity. The two temples 2 abut against the user's ears and abut against the user's nose bridge through the nose pads of the frame 1, 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.

[0083] Meanwhile, as shown in Figure 7, the glasses 100 has an initial position, a first position, and a second position for the temples 2 to rotate relative to the frame 1 via the rotating base 3 about the second axis 61. In this embodiment, the rotation of the temples 2 relative to the frame 1 about the second axis 61 can optionally be performed when the glasses 100 is in the open state and the outward-facing state. That is, when the glasses 100 is in the open state and the outward-facing state, the rotation of the temples 2 about the second axis 61 relative to the frame 1 can be in the initial position, the first position, and the second position, thus making it suitable for users with different head lengths and different nose-ear distances.

[0084] It should be noted that when the glasses 100 is in the open state, and the temple 2 is in its initial position, the extension direction of the temple 2 is consistent with the extension direction of the connecting part or mounting part of the frame 1; when the temple 2 is in the first or second position, the extension direction of the temple 2 forms a certain angle with the extension direction of the connecting part or mounting part of the frame 1. Optionally, the angle formed by the extension direction of the temple 2 and the extension direction of the connecting part or mounting part of the frame 1 is an acute angle.

[0085] Understandably, taking the plane where the light emanating from the user's two eyes is located when the user wears glasses 100 as the horizontal plane, with glasses 100 in the open and outward-folded states, when the temple 2 is in the first position, the end of the temple 2 away from the frame 1 is above the horizontal plane, and the angle formed by the extension direction of the temple 2 and the horizontal plane is an acute angle; when the temple 2 is in the second position, the end of the temple 2 away from the frame 1 is below the horizontal plane, and the angle formed by the extension direction of the temple 2 and the horizontal plane is an acute angle.

[0086] In one embodiment, the second elastic member 7 is provided with a plurality of gear slots 711, and the outer wall of the rotating base 3 is provided with a gear protrusion 332 corresponding to the gear slot 711, and the gear protrusion 332 is movably limited within a gear slot 711.

[0087] In this embodiment, as shown in Figures 5, 6, 9, and 14, a stop groove 711 is provided on the second elastic member 7, and a stop protrusion 332 is provided on the rotating base 3, so that the stop protrusion 332 is movably limited within a stop groove 711. Thus, during the rotation of the temple 2 relative to the frame 1 via the rotating base 3 around the second rotating axis 61, the stop protrusion 332 of the rotating base 3 can be transferred from one stop groove 711 to another stop groove 711, thereby limiting the stop of the temple 2's rotation around the second rotating axis 61 and preventing the problem of over-bending failure.

[0088] It is understood that the number of position slots 711 may include two, three, four, five, or more, and no limitation is made here. Multiple position slots 711 are arranged adjacent to each other. In this embodiment, each position slot 711 of the second elastic member 7 can correspond to different angles of rotation of the temple 2 around the second rotating axis 61.

[0089] Optionally, the plurality of gear slots 711 include a first gear slot 712, a second gear slot 713 and a third gear slot 714 arranged sequentially adjacent to each other.

[0090] In this embodiment, as shown in Figures 5, 6, and 14, the first gear slot 712, the second gear slot 713, and the third gear slot 714 are optionally arranged sequentially along the vertical direction. The planes on which the openings of the first gear slot 712, the second gear slot 713, and the third gear slot 714 are located can be located on the same vertical plane. Of course, in other embodiments, the first gear slot 712, the second gear slot 713, and the third gear slot 714 may also be located on an arc-shaped surface, which is not limited here.

[0091] Understandably, the eyeglasses 100 have an initial position, a first position, and a second position in which the rotating base 3 drives the first connector 4 and the temple 2 to rotate relative to the frame 1 around the second rotating axis 61; in the initial position, the stop protrusion 332 passes through the mounting port 12 and is limited to the second stop groove 713; in the first position, the stop protrusion 332 passes through the mounting port 12 and is limited to the first stop groove 712; in the second position, the stop protrusion 332 passes through the mounting port 12 and is limited to the third stop groove 714.

[0092] It should be noted that when the glasses 100 is in the open or outward-folded state, the temple 2 of the glasses 100 has an initial position, a first position, and a second position, in which the rotating base 3 drives the first connecting member 4 and the temple 2 to rotate relative to the frame 1 around the second rotating axis 61. When the temple 2 is in the initial position, the stop protrusion 332 of the rotating base 3 is confined within the second stop groove 713. When the temple 2 rotates relative to the frame 1 around the second rotating axis 61 from the initial position to the first position, the stop protrusion 332 of the rotating base 3 moves from the second stop groove 713 to the first stop groove 712, that is, when the temple 2 is in the first position, the stop protrusion 332 is confined within the first stop groove 712. When the temple 2 rotates relative to the frame 1 from the initial position to the second position around the second pivot 61, the stop protrusion 332 of the rotating base 3 moves from the second stop groove 713 to the third stop groove 714. That is, when the temple 2 is in the second position, the stop protrusion 332 is confined to the third stop groove 714.

[0093] As can be understood, as shown in Figure 7, temple 2 is located above temple 2 in the initial position in the first position, and temple 2 is located below temple 2 in the initial position in the second position.

[0094] In one embodiment, the second elastic member 7 includes a gear position 71 and two fixing parts 72 connected to both ends of the gear position 71. The gear position 71 is provided with a plurality of gear position grooves 711. The side wall of the mounting groove 11 is provided with a mounting opening 12. The two fixing parts 72 are connected to the outer side wall of the mounting groove 11 so that the gear position 71 corresponds to the mounting opening 12, and the gear position protrusion 332 passes through the mounting opening 12 and is movably limited within a gear position groove 711.

[0095] In this embodiment, as shown in Figures 2, 5, 6, 9, and 14, the second elastic member 7 is configured as a gear position 71 and two fixing parts 72 connected to both ends of the gear position 71. This facilitates the connection of the two fixing parts 72 of the second elastic member 7 to the outer wall of the mounting groove 11, thereby achieving the installation and fixation of the second elastic member 7. The gear position 71 is provided with multiple gear position grooves 711, and a mounting opening 12 is provided on the side wall of the mounting groove 11, so that the gear position 71 corresponds to the mounting opening 12. This allows the gear position protrusion 332 to easily pass through the mounting opening 12 and move within a gear position groove 711.

[0096] It is understood that the material of the second elastic element 7 can be a metal, such as stainless steel, which includes materials such as titanium alloy, nickel-titanium alloy, and beryllium copper; or, the material of the second elastic element 7 can also be a non-metallic material, such as elastic plastic or carbon fiber, etc., without limitation. In this embodiment, when the gear shift protrusion 332 moves from one gear shift groove 711 to another gear shift groove 711 of the second elastic element 7, the gear shift portion 71 of the second elastic element 7 undergoes elastic deformation under the pressure of the gear shift protrusion 332.

[0097] Optionally, the two fixing parts 72 extend in opposite directions. In this embodiment, as shown in Figures 5, 6, 9, and 14, the two fixing parts 72 may be located in the same plane. Of course, in other embodiments, the two fixing parts 72 may also be arranged in parallel, but not in the same plane, which is not limited here.

[0098] Optionally, the two fixing parts 72 extend toward the same side of the gear position part 71. It is understood that the two fixing parts 72 and the gear position part 71 enclose a U-shaped structure, which is not limited here.

[0099] Understandably, the gear shift portion 71 is located between the two fixing portions 72, and a groove structure is formed corresponding to the gear shift protrusion 332. Optionally, the gear shift groove 711 is provided on the bottom wall of the groove formed by the gear shift portion 71. In this embodiment, each fixing portion 72 is connected to the outer wall of the mounting groove 11 by a fastener, which can improve the connection stability of the second elastic member 7. The fixing portion 72 is provided with a screw hole, and the frame 1 is provided with a threaded hole, through which a screw or pin passes and is placed in the threaded hole, which is not limited here.

[0100] In one embodiment, the first elastic member 5 includes a main body 51 and a damping arm 52. One end of the main body 51 is housed in the receiving groove 31, and the other end of the main body 51 forms an outwardly folded elastic piece 511. The outwardly folded elastic piece 511 elastically abuts against the first connecting member 4. The main body 51 is also provided with an elastic through hole 512. One end of the damping arm 52 is connected to the inner wall of the elastic through hole 512, and the other end of the damping arm 52 extends along the elastic through hole 512 and bends to form a damping groove 521.

[0101] In this embodiment, the first elastic element 5 can be selected as a sheet or an elastic plate structure. The material of the first elastic element 5 can be stainless steel or carbon fiber. Optionally, when the material of the first elastic element 5 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 512 in the main body 51 of the first elastic element 5, one end of the damping arm 52 is connected to the inner wall of the elastic through hole 512, and the other end of the damping arm 52 extends along the elastic through hole 512 and bends to form a damping groove 521, thereby improving the elastic performance of the damping arm 52.

[0102] Understandably, the main body 51 of the first elastic element 5 and the damping arm 52 are integrally formed, which improves the connection stability and structural strength between the damping arm 52 and the main body 51. In this embodiment, the inner wall of the damping groove 521 abuts against the outer wall of the first rotating shaft 44, so that frictional damping is formed when the first rotating shaft 44 rotates relative to the damping groove 521, so that the movement of the first rotating shaft 44 has a damped folding feel of the hinge movement, thereby realizing the folding of the temple 2 and making the folding have a damped feel.

[0103] Optionally, the distance from the end of the damping support arm 52 bent to form the damping groove 521 to the damping support arm 52 is defined as the opening width of the damping groove 521, and the opening width is less than or equal to 1 / 3 of the circumference of the first rotating shaft 44. It is understandable that by setting the damping groove 521 of the damping support arm 52 to a semi-open structure, that is, the damping groove 521 partially wraps around the outer wall of the first rotating shaft 44, it is convenient to install the first rotating shaft 44, and it also ensures that the damping groove 521 has good damping effect and damping feel.

[0104] Understandably, the cross-section of the first rotating shaft 44 in the direction perpendicular to the axial direction of the first rotating shaft 44 may be circular, and the cross-section of the damping groove 521 in the direction perpendicular to the axial direction of the first rotating shaft 44 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 44.

[0105] In this embodiment, an outward-folding spring 511 is formed at one end of the main body 51. The outward-folding spring 511 elastically abuts against the first connecting member 4. Thus, when the glasses 100 is in the outward-folding state, when the temple 2 drives the first connecting member 4 to rotate outward relative to the frame 1 around the first pivot 44, the first connecting member 4 drives the outward-folding spring 511 of the first elastic member 5 to elastically deform, thereby generating a torque for the first connecting member 4 to rotate inward, thereby providing a holding force. When the outward-folding force is removed, the elastically deformed outward-folding spring 511 will push the first connecting member 4 to drive the temple 2 back to the original state of the outward-folding spring 511, thereby realizing that the temple 2 can automatically spring back to the original position after the outward-folding force is removed.

[0106] Understandably, the first elastic element 5 can be selected as a spring sheet structure, which has good elasticity. Optionally, the elastic modulus of the first elastic element 5 is 50 GPa to 400 GPa, that is, the elastic modulus of the first elastic element 5 is 50 GPa, 100 GPa, 150 GPa, 200 GPa, 250 GPa, 300 GPa, 350 GPa, 400 GPa, etc., which are not limited here.

[0107] To facilitate the clamping force provided by the outward-folding spring 511 when it folds the first connecting member 4 outward, and to ensure automatic rebound after the outward-folding force is removed, the length of the outward-folding spring 511 in this embodiment is optionally between 5mm and 30mm. Optionally, the length of the outward-folding spring 511 can be 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, etc., and is not limited here. Optionally, the thickness of the outward-folding spring 511 is 0.3mm to 1.5mm, that is, the thickness of the outward-folding spring 511 can be 0.3mm, 0.5mm, 0.8mm, 1mm, 1.3mm, 1.5mm, etc., and is not limited here. It is understood that this setting ensures that the first elastic member 5 has good elasticity.

[0108] In one embodiment, a fixing post 323 protrudes from the bottom wall of the receiving groove 31. The fixing post 323 is located between the first rotating hole 331 and the second rotating hole 321. The main body 51 is fixed to the fixing post 323 by fasteners.

[0109] In this embodiment, as shown in Figures 4 to 6, 9, and 11, a fixing post 323 is provided in the receiving groove 31 of the rotating base 3, and a through hole is provided on the first elastic member 5 corresponding to the fixing post 323. Fasteners are then threaded or inserted through the through hole to the fixing post 323, thus fixing the first elastic member 5 to the rotating base 3. Simultaneously, the fixing post 323 provides support for the first elastic member 5. Optionally, the fixing post 323 is located between the first rotating hole 331 and the second rotating hole 321.

[0110] Understandably, the fixing post 323 may optionally be a threaded post, and the fastener may be a screw or pin.

[0111] In one embodiment, one of the groove wall of the receiving groove 31 and the main body 51 is provided with a latching protrusion 513 and the other of the receiving groove is provided with a latching groove 324, and the latching protrusion 513 is limited to the latching groove 324.

[0112] In this embodiment, as shown in Figures 5, 6, 9, 11, and 13, a locking protrusion 513 and a locking groove 324 are provided in one of the rotating base 3 and the first elastic member 5, respectively. The locking protrusion 513 is confined within the locking groove 324, thereby further realizing the positioning, installation, and locking of the first elastic member 5. It can be understood that the locking protrusion 513 is provided in the first elastic member 5, and the locking groove 324 is provided in the rotating base 3. Thus, with the locking protrusion 513 confined within the locking groove 324, both positioning and locking can be achieved, and the main body 51 of the first elastic member 5 can be supported by the locking protrusion 513 to ensure the deformation capability of the first elastic member 5.

[0113] In one embodiment, the rotating base 3 includes a base plate 32 and a side plate 33. The side plate 33 is disposed around the periphery of the base plate 32 and forms a receiving groove 31 with the base plate 32. The side plate 33 is provided with a first rotating hole 331, and the base plate 32 is provided with a second rotating hole 321 and a sliding hole 322. The side plate 33 is provided with a clearance notch 333 that communicates with the receiving groove 31 near the first rotating hole 331. The end of the first elastic member 5 away from the second rotating hole 321 passes through the clearance notch 333 and elastically abuts against the first connecting member 4. The side plate 33 facing away from the receiving groove 31 is also provided with a stop protrusion 332. The stop protrusion 332 is located at the end of the side plate 33 away from the clearance notch 333 and elastically abuts against the second elastic member 7.

[0114] In this embodiment, as shown in Figures 4 to 6 and Figures 9 to 11, the side plate 33 of the rotating base 3 surrounds the periphery of the base plate 32. The side plate 33 is optionally perpendicular to the base plate 32, so that the side plate 33 and the base plate 32 enclose and form a receiving groove 31. Optionally, the base plate 32 is rectangular or elongated. By providing a clearance notch 333 at one end of the side plate 33 adjacent to the base plate 32, the clearance notch 333 can be used to provide clearance and limiting space for the first elastic member 5, so that one end of the first elastic member 5 passes through the clearance notch 333 and elastically abuts against the first connecting member 4. The other end of the side plate 33 adjacent to the base plate 32 also has a stop protrusion 332 protruding on the side facing away from the receiving groove 31, so that the stop protrusion 332 and the clearance notch 333 are optionally located at both ends of the base plate 32.

[0115] Understandably, the side plate 33 is also provided with a first rotating hole 331, which is located at one end of the side plate 33 adjacent to the clearance notch 333. Optionally, the axial direction of the second rotating hole 321 is perpendicular to the axial direction of the first rotating hole 331. This makes the axial direction of the first rotating shaft 44 perpendicular to the axial direction of the second rotating shaft 61.

[0116] In this embodiment, to prevent the second rotating shaft 61 from affecting the first connecting member 4 and causing the temple 2 to rotate around the first rotating shaft 44, the base plate 32 is provided with a second rotating hole 321 and a sliding hole 322 spaced apart. The second rotating hole 321 is located at the end of the base plate 32 away from the avoidance notch 333. It can be understood that one end of the rotating base 3 is accommodated in the mounting groove 11 of the frame 1, and the other end of the rotating base 3 is rotatably connected to the first connecting member 4.

[0117] In order to ensure that the rotating base 3 can rotate relative to the frame 1 around the second rotating shaft 61, in one embodiment, the bottom wall of the receiving groove 31 is provided with a rotating cylinder 325 protruding around the second rotating hole 321. The second rotating shaft 61 is rotatably inserted through the first through hole 13 and the second rotating hole 321 in sequence, and rotates and abuts against the inner wall of the rotating cylinder 325.

[0118] As can be understood, as shown in Figures 9 and 11, by protruding a rotating cylinder 325 on the base plate 32 of the rotating base 3, the rotating cylinder 325 is arranged around the second rotating hole 321. In this way, the second rotating shaft 61 is rotated and passes through the first through hole 13 and the second rotating hole 321 in sequence, and rotates and abuts against the inner wall of the rotating cylinder 325, thereby using the rotating cylinder 325 to provide rotation and limiting space for the second rotating shaft 61.

[0119] In one embodiment, the sliding holes 322 include a plurality of sliding holes 322, which are spaced apart around the second rotating hole 321. The second through holes 14 include a plurality of second through holes 14, which are spaced apart around the first through hole 13. The sliding holes 322 and the second through holes 14 are arranged in a one-to-one correspondence. The second connector 6 is provided with a plurality of sliding shafts 62, which are spaced apart around the second rotating shaft 61. Each sliding shaft 62 is movably inserted into a second through hole 14 and a sliding hole 322.

[0120] In this embodiment, as shown in Figures 5, 6, and 9, the number of sliding holes 322 is the same as the number of second through holes 14, and they are arranged in a one-to-one correspondence. The number of sliding shafts 62 is the same as the number of sliding holes 322 and second through holes 14, and they are arranged in a one-to-one correspondence. Optionally, the axial direction of the second rotating hole 321 is parallel to the axial direction of the sliding hole 322.

[0121] To facilitate the movement of the sliding shaft 62 along the sliding hole 322 when the rotating base 3 rotates around the second rotating shaft 61, optionally, the sliding hole 322 is arranged in an arc shape with the center of the second rotating hole 321 as the center. In this embodiment, as shown in Figures 5, 6, and 9, there are three sliding holes 322, three through holes 14, and three sliding shafts 62, and the three sliding holes 322 are arranged at intervals around the second rotating hole 321. Optionally, the line connecting the three sliding holes 322 is arranged in a semi-circular arc shape.

[0122] Understandably, in order to facilitate the connection and fixation of the second connector 6 between the frame 1 and the rotating base 3, and to ensure that the rotating base 3 rotates around the second axis 61 within the mounting groove 11, the first through hole 13 and the second through hole 14 provided on the bottom wall of the mounting groove 11 of the frame 1 are both circular.

[0123] In one embodiment, the second connecting member 6 includes a connecting plate 63 and a second rotating shaft 61 and a sliding shaft 62 protruding from the connecting plate 63. The second rotating shaft 61 is provided with a fixing hole 611. The second connecting member 6 also includes a fixing member 64. One end of the fixing member 64 forms a limiting platform 641. The second rotating shaft 61 is rotatably inserted into the first through hole 13 and the second rotating hole 321 in sequence, so that the frame 1 is clamped between the connecting plate 63 and the rotating base 3. One end of the fixing member 64 is provided in the fixing hole 611 so that the limiting platform 641 and the rotating base 3 can be movably abutted.

[0124] In this embodiment, as shown in Figures 2 to 4 and Figure 9, the connecting plate 63 of the second connector 6 is used to set the second rotating shaft 61 and the sliding shaft 62. By providing a fixing hole 611 in the second rotating shaft 61, the second rotating shaft 61 is rotated and passes through the first through hole 13 and the second rotating hole 321 in sequence, and the sliding shaft 62 is passed through the second through hole 14 and the sliding hole 322 in sequence. The frame 1 is sandwiched between the connecting plate 63 and the rotating base 3. One end of the fixing member 64 is provided in the fixing hole 611 so that the limiting platform 641 and the rotating base 3 can be movably abutted. In this way, the installation and rotational connection of the second connector 6, the frame 1 and the rotating base 3 can be realized.

[0125] Understandably, in order to hide the connecting plate 63 of the second connector 6, a groove is provided on the frame 1 corresponding to the connecting plate 63 of the second connector 6. Thus, when the second connector 6 is connected to the frame 1, the connecting plate 63 is accommodated and limited within the groove, which is not limited here.

[0126] In one embodiment, there are two first rotating holes 331, which are coaxially arranged and located on opposite sides of the receiving groove 31; the first connecting member 4 includes a first connecting part 41 and two rotating arms 42 provided at both ends of the first connecting part 41. The two rotating arms 42 and the first connecting part 41 surround each other to form a relief groove 43. Each rotating arm 42 has a mounting hole 421 at one end away from the first connecting part 41. The first connecting part 41 is connected to the temple 2; wherein, the first rotating shaft 44 is sequentially inserted into the mounting hole 421, the first rotating hole 331 and the damping groove 521, and both ends of the first rotating shaft 44 are fixed in the two mounting holes 421 so that part of the rotating base 3 is accommodated in the relief groove 43. The end of the first elastic member 5 away from the second rotating hole 321 elastically abuts against the first connecting part 41.

[0127] In this embodiment, as shown in Figures 5, 6, and 9 to 11, the base plate 32 of the rotating base 3 is optionally rectangular. The side plates 33 of the rotating base 3 are parallel and opposite to each other on the two long axis sides of the base plate 32. That is, each side plate 33 on the two long axis sides of the base plate 32 is provided with a first rotating hole 331, and the two first rotating holes 331 are coaxially arranged. Optionally, the line connecting the two first rotating holes 331 is perpendicular to the axial direction of the second rotating shaft 61.

[0128] As can be understood, as shown in Figures 9, 10, and 12, by configuring the first connector 4 as a first connecting portion 41 and two rotating arms 42 located at both ends of the first connecting portion 41, the two rotating arms 42 and the first connecting portion 41 enclose a U-shaped clearance groove 43. A mounting hole 421 is provided at the end of the rotating arm 42 away from the first connecting portion 41. Thus, the first connecting portion 41 of the first connector 4 is connected to the temple 2. A rotating shaft 44 is sequentially inserted into the mounting hole 421, the first rotating hole 331, and the damping groove 521, with both ends of the first rotating shaft 44 fixed within the two mounting holes 421, allowing part of the rotating base 3 to be accommodated within the clearance groove 43, thereby achieving a rotational connection between the first connector 4 and the rotating base 3. Optionally, the first connector 4 and the temple 2 can be connected and fixed by welding, bonding, or using screws, pins, etc.

[0129] In one embodiment, the first rotating shaft 44 includes a rotating shaft portion 441 and mounting portions 442 connected to both ends of the rotating shaft portion 441. The rotating shaft portion 441 passes through the first rotating hole 331 and the damping groove 521 in sequence. Each mounting portion 442 is confined within a mounting hole 421. The mounting hole 421 has at least one mounting surface 422, and the mounting portion 442 has a limiting surface 443 that cooperates with the mounting surface 422.

[0130] In this embodiment, as shown in Figures 9 to 12, by providing limiting planes 443 at both ends of the first rotating shaft 44 and providing a mounting plane 422 in the mounting hole 421, when the mounting part 442 of the first rotating shaft 44 is limited within the mounting hole 421, the limiting planes 443 and the mounting plane 422 are used for limiting cooperation, thereby ensuring that the first connecting member 4 rotates synchronously with the first rotating shaft 44, that is, the first connecting member 4 drives the first rotating shaft 44 to rotate relative to the first rotating hole 331 and the damping groove 521.

[0131] Understandably, the cross-section of the shaft portion 441 of the first rotating shaft 44 may optionally be circular. Optionally, the mounting hole 421 is a polygonal hole, and the first rotating hole 331 is a circular hole. In this embodiment, the first rotating shaft 44 is a pin with a different cross-section, and both ends of the first rotating shaft 44 are flat shafts, used to fix it together with the mounting hole 421 of the first connector 4, for example, by interference fit, spot welding, bonding, etc. The first rotating shaft 44 and the first rotating hole 331 of the rotating base 3 are fitted with a rotatable cylindrical hole to form a rotation center for mutual rotation between the two.

[0132] In one embodiment, as shown in Figures 9 to 11, the first connecting portion 41 is recessed to form a relief groove 411 that communicates with the relief groove 43. A support platform 412 is provided on the side of the relief groove 411 adjacent to the relief groove 43. The end of the first elastic member 5 away from the second rotating hole 321 extends into the relief groove 411 and is elastically supported on the support platform 412.

[0133] Understandably, by providing a clearance groove 411 in the first connecting part 41 of the first connector 4, on the one hand, the clearance groove 411 provides clearance space for the outward-turning spring piece 511 of the first elastic member 5, and on the other hand, the clearance groove 411 can also provide limiting space for the outward-turning spring piece 511.

[0134] In one embodiment, the first connecting member 4 further includes a limiting part 45, the two ends of the limiting part 45 being connected to the ends of the two rotating arms 42 away from the first connecting part 41, and the limiting part 45 being located on the side of the first elastic member 5 facing away from the receiving groove 31. The first elastic member 5 has an outwardly folded spring piece 511 that elastically abuts against the first connecting part 41.

[0135] In this embodiment, as shown in Figures 9 to 11, by providing a limiting part 45 on the first connecting member 4, the two ends of the limiting part 45 are respectively connected to the ends of the two rotating arms 42 away from the first connecting part 41, so that the limiting part 45 can achieve the limiting function when the temple 2 rotates relative to the rotating base 3 around the first rotating axis 44 through the first connecting member 4.

[0136] Understandably, the eyeglasses 100 have a folded state, an open state, and an outward-folding state, in which the first connecting member 4 drives the temple 2 to rotate around the first pivot 44 relative to the rotating base 3 and the frame 1. In the folded state, the temple 2 is close to the frame 1, and the first connecting part 41 is away from the first elastic member 5, while the limiting part 45 is close to the outward-folding spring 511. In the open state, the temple 2 is away from the frame 1 and is perpendicular to the frame 1, the first connecting part 41 abuts against the outward-folding spring 511, and the limiting part 45 is away from the outward-folding spring 511. In the outward-folding state, the temple 2 is set at an obtuse angle to the frame 1, and the first connecting part 41 causes the outward-folding spring 511 to deform.

[0137] It should be noted that when the glasses 100 is in the folded state, the rotating arm 42 of the first connector 4 is approximately perpendicular to the base plate 32 of the rotating base 3, and the limiting part 45 is close to the outward-folding spring 511. When the glasses 100 is in the open state, the limiting part 45 is located on the side of the side plate 33 of the rotating base 3 away from the base plate 32. When the glasses 100 is in the outward-folding state, when the first connecting part 41 of the first connector 4 causes the outward-folding spring 511 to deform to its maximum deformation, the limiting part 45 abuts against the side plate 33 of the rotating base 3 to prevent the temples 2 from excessively folding outward.

[0138] In one embodiment, the glasses 100 further includes a protective plate 8 and a housing 9. The protective plate 8 is housed in the receiving groove 31 and connected to the side of the first elastic member 5 facing away from the bottom wall of the receiving groove 31. The protective plate 8 is provided with a wire passage groove 81 on the side facing away from the first elastic member 5. The housing 9 covers the opening of the receiving groove 31 and cooperates with the wire passage groove 81 to form a wire routing channel 91.

[0139] In this embodiment, as shown in Figures 2, 4, and 9, by providing a protective plate 8 and a housing 9, the protective plate 8 provides wiring or mounting space for the flexible circuit board of the optical system connecting the glasses 100. It is understood that the protective plate 8 is housed within the receiving groove 31, and the protective plate 8 and the first elastic element 5 are sequentially fixed to the fixing post 323 of the rotating base 3 using fasteners, thereby achieving the installation and fixation of the protective plate 8.

[0140] Understandably, by providing a wire routing groove 81 on the side of the protective plate 8 facing away from the first elastic member 5, it is convenient to use the wire routing groove 81 to realize the installation of wires or flexible circuit boards. In this embodiment, by providing a housing 9, on the one hand, it is to protect the cables or flexible circuit boards in the wire routing groove 81, and on the other hand, it is to improve the appearance.

[0141] Optionally, the housing 9 is detachably mounted on the opening of the receiving groove 31 and cooperates with the wire guide groove 81 to form a wiring channel 91. It is understood that by adopting a detachable connection between the housing 9 and the rotating base 3, the housing 9 can be easily removed at any time, making it convenient to install cables or flexible circuit boards in the wire guide groove 81.

[0142] The eyeglasses 100 of this application mainly involve two degrees of freedom of rotation axes: a first rotation axis 44 (axis A) as shown in Figure 4 and a second rotation axis 61 (axis B) as shown in Figures 5 and 6. Axis A is used to realize the folding, unfolding, and outward-folding functions of the temples 2. Understandably, the folding function is used to fold and store the temples 2, and the outward-folding function is used to adjust the comfort for users with different head widths. Axis B is used to realize the lateral adjustment function of the temples 2, and axis B has three adjustment levels to meet the comfort adjustment needs of users with different head shapes and different nose-ear ratios.

[0143] As can be understood, Figure 10 shows a schematic diagram of the hinge structure. The first connector 4, the rotating base 3, and the first elastic element 5 can be pre-assembled together as a single module via the first rotating shaft 44. Then, the second connector 6, the second elastic element 7, the protective plate 8, and the outer shell 9 are assembled sequentially.

[0144] In this embodiment, the first connector 4, the rotating base 3, and the first elastic element 5 are assembled into a hinge module via the first rotating shaft 44. The first connector 4 is rigidly connected to the temple 2 via screws, adhesive, or other fixing methods. This hinge module is connected and fixed to the rotating base 3 of the hinge module via the second rotating shaft 61 of the second connector 6, which passes through the first through hole 13 on the frame 1. The second elastic element 7 is also fixed to the frame 1, so that the stop protrusion 332 of the rotating base 3 and the stop groove 711 of the second elastic element 7 cooperate to connect the hinge module to the frame 1. The hinge module is used to realize the axis A movement of the temple 2 and provide the outward rotation force. After the hinge module is assembled with the frame 1 via the cooperation of the second connector 6 and the second elastic element 7, it is used to realize the lateral movement of the temple 2 and provide the force (i.e., axis B). As shown in Figures 4 and 8, axis A is used to realize folding and outward rotation; as shown in Figures 5, 6 and 7, axis B is used to realize the side axis adjustment function of temple 2.

[0145] Understandably, the temple 2 of the eyeglasses 100 and the frame 1 are hinged together to achieve outward folding and folding damping. When the temple 2 is rotated, the first connecting piece 4 will rotate. The rotating base 3 is fixed to the frame 1. The first elastic member 5 is a metal plate with good elasticity. The outward folding spring 511 on the first elastic member 5 is used to provide clamping force when folding outward and automatic rebound after the outward folding force is removed. The damping groove 521 of the damping arm 52 of the first elastic member 5 is used to provide damping force during the rotation of the temple 2, so that there is a certain damping feeling during the movement. The first rotating shaft 44 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 4, for example, by interference fit, spot welding, bonding, etc. The fixation of the first rotating shaft 44 and the rotating base 3 is a rotatable round hole cylindrical fit to form a rotating central shaft A for mutual rotation between the two. Therefore, when the temple 2 is folded, the temple 2 will drive the first connecting piece 4 inward, and form a folding motion with the rotating base 3 through the first rotating shaft 44. The first rotating shaft 44 and the first connecting piece 4 rotate together. The rotation of the first rotating shaft 44 will form frictional damping with the damping groove 521 of the first elastic member 5, so that the hinge movement has a damped folding feel during the movement, thereby realizing the folding of the temple 2 and making the folding have a damped feel.

[0146] When the temple 2 is turned outwards to accommodate users with different head widths, the temple 2 will cause the first connecting piece 4 to rotate outwards. The rotating first connecting piece 4 will cause the outward-turning spring piece 511 on the first elastic member 5 to deform elastically, thereby generating a torque that pushes the first connecting piece 4 to rotate inwards, thus providing a supporting force. When the outward-turning force is removed, the elastically deformed outward-turning spring piece 511 will push the first connecting piece 4 to drive the temple 2 back to the original state of the spring piece, thereby realizing that after the outward-turning force is removed, the temple 2 can automatically spring back to the original position.

[0147] Understandably, the temples 2 and frame 1 of the glasses 100 can also be adjusted along the side axis to allow for angle adjustment between the temples 2 and frame 1, accommodating users with different head shapes. The second connector 6 extends from the inside of the frame 1, allowing the second rotating shaft 61 to pass through the corresponding first through hole 13 on the frame 1, then through the corresponding second rotating hole 321 on the rotating base 3, and finally be fixed by the fixing member 64. Since the three sliding shafts 62 of the second connector 6 are positioned with the corresponding second through holes 14 on the frame 1, and then fixed by the fixing member 64, the second connector 6 is completely fixed to the frame 1. The rotating base 3 and the second connector 6 are connected by a cylinder (second rotating shaft 61) and a hole (second rotating hole 321). The second rotating hole 321 and the rotating cylinder 325 of the rotating base 3, together with the second rotating shaft 61 of the second connector 6, form a rotation center axis B. This allows the hinge module to drive the temples 2 to rotate relative to the frame 1 and the second connector 6 along the rotation center axis B. Since the stop protrusion 332 of the rotating base 3 and the stop groove 711 on the second elastic member 7 have corresponding position limiting protrusions and grooves, the temple 2 can stay in any groove (i.e., stop groove 711). When the temple 2 is rotated laterally, the stop protrusion 332 presses the stop groove 711 of the second elastic member 7 to undergo elastic deformation. When the stop protrusion 332 rotates to the decomposition line of the adjacent stop groove 711, the elastic deformation of the second elastic member 7 returns to normal and pushes the stop protrusion 332 to rotate into the adjacent stop groove 711, thus completing the angle adjustment between the temple 2 and the frame 1. The schematic diagram after rotation is shown in Figures 5 and 6.

[0148] The sliding shaft 62 can slide within the corresponding sliding hole 322 on the rotating base 3, which enhances the resistance to deformation when the temple 2 is twisted, and prevents failure due to over-bending. The second elastic element 7 can be flat, U-shaped, or other shapes. The material of the second elastic element 7 can be stainless steel, including materials such as titanium alloy, nickel-titanium alloy, and beryllium copper; or, the material of the second elastic element 7 can be composite materials such as carbon fiber. Optionally, the elastic modulus of the second elastic element 7 can be 50 GPa to 400 GPa. By adjusting the spacing and angle of the stop groove 711 on the second elastic element 7, the adjustment angle of the temple 2 can be changed within the range of 1 degree ± 30 degrees.

[0149] This application also proposes an AR device, which includes an optical system and the aforementioned glasses 100, with the optical system connected to the frame 1 of the glasses 100. The specific structure of the glasses 100 is as described in the foregoing embodiments. Since this AR device 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 elaborated here.

[0150] In this embodiment, the AR device includes a flexible circuit board, one end of which passes through the wiring channel 91 and is electrically connected to the optical system. It is understood that the temple 2 of the glasses 100 has a mounting cavity or other structure for installing a power supply, and the other end of the flexible circuit board is guided through the wiring channel 91 to the mounting cavity of the temple 2 and electrically connected to the power supply or other components; this is not limited here.

[0151] It is understandable that AR devices can be virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR) glasses, and no specific limitation is made here.
