Description

Smart glasses

[0001] This disclosure claims priority to Chinese patent application number CN202311865772.7 filed with the State Intellectual Property Office on December 29, 2023, with the invention name “Smart Glasses,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the technical field of wearable devices, and in particular to smart glasses. Background Art

[0003] In related art, the frame of smart glasses typically consists of a front frame, a bracket, and a back shell. The bracket is fixed between the front frame and the back shell, connecting the front frame to the back shell, and the temples to the back shell. The camera is usually fixed to the bracket and extends from the front frame. Under the action of external forces, the deformation path caused by the temples expanding outward is the back shell-front frame-bracket-camera, affecting the position and angle accuracy of the camera. The transmission of deformation can be reduced by designing the fixing method of the back shell to the front frame, the back shell to the bracket, or the front frame to the bracket. Summary of the Invention

[0004] An embodiment of the present disclosure provides smart glasses.

[0005] The smart glasses include: a frame and temples. The frame includes a front frame and a crossbeam. The front frame is connected to the crossbeam. There is a deformation gap between the crossbeam and the front frame. The temples are rotatably connected to the crossbeam, which can cause the crossbeam to deform and move closer to the front frame.

[0025] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] Some embodiments of the present disclosure provide glasses comprising a frame and temples. The temples are connected to the frame and are rotatable relative to the frame. Optionally, the temples can be extended outward relative to the frame to adapt the glasses to wearers with different head circumferences.

[0030] In some optional embodiments, the glasses are smart glasses, and the smart glasses are further provided with a sensor 6. Optionally, the sensor 6 includes a sensor 6 capable of capturing at least one of position or posture. For example, it can be a camera or an inertial measurement unit (IMU). The camera can capture images required for SLAM (simultaneous localization and mapping) to provide vision-based tracking and positioning, which can be used for positioning the smart glasses and recognizing interactive gestures. The inertial measurement unit can be used to provide motion data. Optionally, the sensor 6 can be provided on the frame.

[0031] FIG1 shows an exploded view of the local structure of the glasses provided in some embodiments of the present disclosure. As shown in FIG1 , the glasses 100 include a frame 3 and temples 2, and the temples 2 are connected to both sides of the frame 3. The frame 3 includes a front frame 31 and a crossbeam 32. The crossbeam 32 is connected to the front frame 31, and there is a deformation gap between the crossbeam 32 and the front frame 31. The front frame 31 is the appearance part of the glasses 100 and can carry goggles. The front frame 31 is usually a plastic part and is prone to deformation. The temples 2 are rotatably connected to the crossbeam 32. When the temples 2 are spread outward, the crossbeam 32 will be slightly deformed, causing the crossbeam 32 to move closer to the front frame 31.

[0032] If the front frame 31 is fixedly connected to the crossbeam 32 along its entire length, deformation of the crossbeam 32 will also cause the front frame 31 to deform synchronously, affecting the appearance of the glasses 100 and easily causing the front frame 31 to crack. By forming a deformation gap between the crossbeam 32 and the front frame 31 and connecting the temples 2 only to the crossbeam 32 and not to the front frame 31, the front frame 31 does not deform with the deformation of the crossbeam 32, thus reducing the impact of deformation of the crossbeam 32 on the front frame 31.

[0033] In some optional embodiments, the smart glasses include a frame 3 and temples 2. The frame 3 includes a front frame 31 and a crossbeam 32 connected to the front frame 31. The temples 2 are rotatably connected to the crossbeam 32. As the rotation angle of the temples 2 increases, the crossbeam 32 deforms, and the two ends of the crossbeam 32 gradually approach the front frame 31, and the distance between the ends of the front frame 31 and the adjacent surfaces of the crossbeam 32 gradually decreases. The minimum distance between the ends of the front frame 31 and the surfaces adjacent to the crossbeam 32 is greater than 0. Therefore, the force exerted on the ends of the front frame 31 by the crossbeam 32 is much smaller than the force exerted on the crossbeam 32 by the temples 2. For example, the force exerted on the ends of the front frame 31 by the crossbeam 32 can always be 0.

[0034] In some optional embodiments, the smart glasses include a frame 3 and temples 2. The frame 3 includes a front frame 31 and a crossbar 32 connected to the front frame 31. The temples 2 are rotatably connected to the crossbar 32. When the temples 2 rotate, the deformation at the ends of the front frame 31 is much smaller than the deformation at the ends of the crossbar 32. Furthermore, the deformation at the ends of the front frame 31 is less than a preset deformation threshold. For example, the deformation at the ends of the front frame 31 can be zero.

[0035] Optionally, the frame 3 of the glasses 100 also includes a rear frame. The front frame 31 and the rear frame are connected, forming a storage space between them, and the crossbeam 32 is disposed within the storage space. It should be understood that the terms "front frame" and "rear frame" are not meant to limit the positions of the two components; they are simply used to facilitate distinction. Those skilled in the art can configure the components and their positions to implement the embodiments of the present disclosure based on the operating principles.

[0036] In some optional embodiments, the glasses 100 are smart glasses and include a sensor 6. The sensor 6 comprises a sensor capable of capturing at least one of position or posture. For example, it may be a camera or an inertial measurement unit. The sensor 6 may be located on the front frame 31 near the deformation gap. When the crossbeam 32 deforms, the area on the front frame 31 where the sensor 6 is located will not substantially deform. This ensures that the position and posture of the sensor 6 remain unchanged, thus maintaining the data collected by the sensor 6.

[0037] In some possible implementations, the sensor 6 may include cameras, positioned at both ends of the front frame 31. A deformation gap may be provided between the ends of the crossbeam 32 and the front frame 31, so that deformation of the ends of the crossbeam 32 has minimal impact on the ends of the front frame 31. The sensors 6 may be positioned at both ends of the front frame 31. When the temples 2 are extended, the ends of the crossbeam 32 experience significant deformation. Because the crossbeam 32 and the ends of the front frame 31 are not in direct contact, deformation of the ends of the crossbeam 32 does not interfere with contact with the ends of the front frame 31. Consequently, deformation of the front frame 31 does not affect the position and posture accuracy of the cameras.

[0038] In some possible implementations, a camera hole 311 may be provided on the front frame, and the camera 6 is located inside the front frame, covering the camera hole 311. The front frame can protect the camera 6. The front frame and the camera 6 can be connected and fixed using any of an adhesive structure, a snap-on structure, and a fastener connection structure.

[0039] In some possible embodiments, the middle part of the front frame 31 is fixedly connected to the cross beam 32, and the sensor 6 is arranged at the end of the front frame 31; the smart glasses 100 also include a cable, the cable is connected to the sensor 6, and the cable extends along the inner wall of the front frame 31 from the end of the front frame 31 to the middle part of the front frame 31 and extends to the cross beam 32.

[0040] The cable section located between the end of the front frame 31 and the middle of the front frame 31 extends along the inner wall of the front frame 31. The cable can be connected to the inner wall of the front frame 31 and to the middle of the crossbeam 32 to prevent the crossbeam 32 from deforming and causing the cable to move, thereby affecting the camera 6.

[0041] In some possible implementations, the mirror frame 3 includes a deformable element 352 . The deformable element 352 is located in the deformation gap. The deformable element 352 is positionally engaged with at least one of the front frame 31 and the crossbeam 32 .

[0042] The deformable element 352 can be an elastic element that can buffer external forces when applied and restore its deformation after the external force is removed. For example, the elastic element can be a spring. Alternatively, the deformable element 352 can be a flexible element that deforms when subjected to external forces and restores its deformation after the external force is removed. For example, the flexible element can be a flexible gasket or foam to cushion the impact of deformation of the crossbeam 32 on the front frame 31. By placing the deformable element 352 within the deformation gap, the impact of deformation of the crossbeam 32 on the front frame 31 can be absorbed, reducing deformation of the front frame 31 and allowing the sensor 6 to maintain a precise angle, improving the user experience.

[0043] It should be noted that the above-mentioned deformable element 352 can only cooperate with the crossbeam 32 for position limiting. Alternatively, the above-mentioned deformable element 352 can also only cooperate with the front frame 31 for position limiting. Alternatively, the above-mentioned deformable element 352 can also cooperate with both the crossbeam 32 and the front frame 31 for position limiting. Regarding "position limiting", it can be understood that the deformable element 352 elastically presses against at least one of the crossbeam 32 and the front frame 31 to achieve position limiting through elastic force. It can also be understood that a specific position limiting structure is provided in the crossbeam 32 and the front frame 31, and the deformable element 352 can be connected to the position limiting structure. The position limiting portion limits the deformable element 352 to prevent the deformable element 352 from falling off. The position limiting structure can be any one of a protrusion (such as a position limiting column) and a groove. Of course, the position limiting structure can also be other structures, and is not limited to the only one in this disclosure.

[0044] In some possible embodiments, the frame 3 includes a deformable element 352 and a side connector 351. The side connector 351 is provided at the end of the crossbeam 32 along the length direction, and the side connector 351 connects the crossbeam 32 and the front frame 31. The deformable element 352 is provided on the side connector 351.

[0045] Illustratively, the side connecting member 351 is at least partially located between the cross beam 32 and the front frame 31 , and the side connecting member 351 can be fixedly connected to the cross beam 32 and the front frame 31 respectively by bonding, snapping or fastener connection.

[0046] Exemplarily, the side connector 351 can be made of a rigid material. For example, the side connector 351 can be a rigid connector, and the deformable element 352 can be disposed within the gap formed between the crossbeam 32 and the front frame 31 and mounted on the rigid connector. Alternatively, the deformable element 352 can be passed through the rigid connector and positioned within the gap formed between the crossbeam 32 and the front frame 31. Alternatively, the deformable element 352 can be, for example, a flexible washer or foam. The rigid connector can be, for example, a screw.

[0047] Exemplarily, at least two deformable elements 352 are provided at each end of the front frame 31. The deformable elements 352 at each end of the front frame 31 are arranged sequentially along the height direction of the front frame. The deformable elements 352 have a central hole. Each rigid connector sequentially passes through the crossbeam 32 and the central hole of the corresponding deformable element 352 to be connected to the front frame.

[0048] In some possible implementations, as shown in FIG1 and FIG4 , the mirror frame 3 includes a middle connector 34 , which is disposed in the middle of the crossbeam 32 along the length direction, and connects the crossbeam 32 and the front frame 31 .

[0049] Optionally, the middle connecting member 34 can be made of a rigid material. The middle portion of the crossbeam 32 is farthest from the temples 2 at both ends, so the rotation of the temples 2 has little effect on the middle portion of the crossbeam 32. Therefore, the middle portion of the crossbeam 32 and the front frame 31 can be connected and fixed by the middle connecting member 34 made of a rigid material. By rigidly connecting the middle portion of the front frame 31 and the crossbeam 32, significant relative vibration between the front frame 31 and the crossbeam 32 can be avoided, ensuring better integration of the front frame 31 and the crossbeam 32. The middle connecting member 34 made of a rigid material can be a screw.

[0050] Optionally, the central connector 34 can also be made of a deformable material. Although the temples 2 are connected to the ends of the crossbar 32, when both temples 2 are folded inward simultaneously, the central portion of the crossbar 32 inevitably deforms to a certain extent, causing the crossbar 32 to cause a certain degree of deformation of the front frame 31. The central connector 34 is at least partially located between the front frame 31 and the crossbar 32, buffering and absorbing the deformation of the crossbar 32 and reducing the impact of the deformation of the crossbar 32 on the front frame 31. The central connector 34 can be fixedly connected to the crossbar 32 and the front frame 31 respectively by bonding, clamping, or fasteners.

[0051] Alternatively, the middle connector 34 may be formed from a combination of rigid and deformable materials. For example, the middle connector 34 may include a deformable element and a rigid connector. The deformable element may be positioned between the crossbeam and the front frame and attached to the rigid connector. For example, the rigid connector may be inserted through the deformable element, the crossbeam, and the front frame to securely connect the three. The deformable element may be a flexible washer or foam, and the rigid connector may be a screw.

[0052] FIG5 shows a schematic diagram of a connection mechanism 1 connecting a frame 3 and a temple 2 of glasses 100 provided in some embodiments of the present disclosure, and FIG6 shows an exploded view of a partial structure of glasses 100 provided in some embodiments of the present disclosure. As shown in FIG5 and FIG6, the smart glasses 100 include a frame 3, temples 2, and a connection mechanism 1, wherein the temples 2 are connected to the frame 3 via the connection mechanism 1. The connection mechanism 1 enables relative rotation between the temples 2 and the frame 3 to adjust the angle of the temples 2 relative to the frame 3.

[0053] In some optional embodiments, as shown in Figures 5 and 6, the connecting mechanism 1 includes a support 11 and a connecting bracket 12. The support 11 is connected to the temple 2. The connecting bracket 12 is connected to the end of the crossbeam 32 along the length of the crossbeam 32. The support 11 and the connecting bracket 12 are rotatably connected to enable the temple 2 to rotate relative to the frame 3 about a first axis. The first axis can be the rotational axis along which the temple 2 is extended outward about the frame 3. During the rotation of the temple 2 about the first axis, the temple 2 is extended.

[0054] In the disclosed embodiment, the support 11 is used to connect the temple 2, and the connecting bracket 12 is used to connect the frame 3, thereby connecting the temple and frame 3. When the support 11 and the connecting bracket 12 rotate relative to each other, the temple 2 rotates relative to the frame 3, allowing the angle between the temple 2 and the frame 3 to be adjusted, making the glasses 100 suitable for wearers with different head circumferences. In some possible embodiments, the sensor 6 and the connecting bracket 12 are positioned opposite each other along the thickness of the frame 3, and a deformation gap is formed between the sensor 6 and the connecting bracket 12.

[0055] It can be understood that the thickness direction of the frame 3 refers to the direction perpendicular to the plane where the front frame 31 is located.

[0056] Optionally, the ends of the connecting bracket 12 and the crossbeam 32 can be fixedly connected using fasteners. A deformation gap is provided between the sensor 6 disposed on the front frame 31 and the connecting bracket 12. When the temples 2 are opened, the connecting bracket 12 approaches the front frame 31 but does not contact the sensor 6.

[0057] In some possible embodiments, as shown in conjunction with Figures 6 and 10 , support 11 includes a first extension portion 111 and a second extension portion 114, which are connected. Optionally, first extension portion 111 and second extension portion 114 may extend in different directions, i.e., an angle may be formed between first extension portion 111 and second extension portion 114. Alternatively, first extension portion 111 and second extension portion 114 may extend along a curve, for example, along an arc.

[0058] In some embodiments of the present disclosure, as shown in FIG6 , the connecting bracket 12 includes opposing limiting portions 121. The opposing limiting portions 121 can accommodate the second extension portion 114 and provide space for movement of the second extension portion 114. Optionally, two spaced and opposing limiting portions 121 can be provided.

[0059] Optionally, the support 11 and the connecting bracket 12 are rotatably connected, and the second extension portion 114 of the support 11 is located between the oppositely disposed limiting portions 121. The second extension portion 114 can rotate about the first axial direction, thereby reaching the limit position of the relative rotation of the temple 114, that is, defining the relative rotation range of the second extension portion 114. In this way, the relative rotation range of the temple and the frame can be limited.

[0060] In some embodiments of the present disclosure, the first axis can be the rotation axis of the temple 2 extending outward about the frame 3. When the second extension portion 114 of the connecting bracket 12 is restrained by the stop portion 121 on one side, a first angle is formed between the temple 2 and the frame 3. When the second extension portion 114 is restrained by the stop portion 121 on the other side, a second angle is formed between the temple 2 and the frame 3. In this way, the temple 2 and the frame 3 can rotate between the first angle and the second angle.

[0061] In some possible implementations, the extension direction of the first extension portion 111 is substantially parallel to the length direction of the temple 2, and the second extension portion 114 is substantially parallel to the length direction of the crossbeam 32 when it abuts against one of the limiting portions 121. The first extension portion 111 and the second extension portion 114 are substantially perpendicular to each other, and the first extension portion 111 and the second extension portion 114 may also form an obtuse angle slightly greater than 90 degrees. The angle of the first extension portion 111 and the second extension portion 114 can be adapted to the angle required between the frame 3 and the temple 2 when the temple 2 is in the open state. When the temple 2 drives the first extension portion to rotate, the second extension portion 114 swings along the thickness direction of the frame 3, and the two limiting portions 121 limit the swing range of the second extension portion 114.

[0062] In some possible embodiments, the second extension 114 deforms the crossbeam 32 when it abuts one of the stoppers 121. The two stoppers 121 are positioned sequentially along the thickness of the frame 3, one closer to the wearer and one further away from the wearer. When the temples 2 are unfolded, the second extension 114 abuts the stopper 121 closer to the wearer, causing the crossbeam 32 to deform toward the wearer's face. When the temples 2 are folded to their limit position, the second extension 114 abuts the stopper 121 farther from the wearer, causing the crossbeam 32 to deform toward the wearer's front.

[0063] In some possible implementations, as shown in conjunction with Figures 6 and 7 , in some embodiments of the present disclosure, an elastic component 13 may be further disposed within the connecting mechanism 1. The elastic force of the elastic component 13 may serve as a restoring force for the movement of the support 11 relative to the connecting bracket 12, that is, a damping force for the relative movement between the temple and the frame.

[0064] Optionally, the elastic component 13 is used to provide a damping force that prevents the temples 2 from expanding outward relative to the frame 3. When the glasses are worn on the wearer's head, the temples expand outward. The damping force provided by the elastic component 13 enables the temples 2 to clamp onto the wearer's head, thereby allowing the temples 2 to share the pressure from the nose pads and ensuring that the glasses are stably worn on the wearer's head.

[0065] In some embodiments of the present disclosure, as shown in FIG6 , the elastic component 13 is located between the support 11 and the connecting bracket 12, and is used to provide a restoring force for the first extension portion 111 to rotate closer to the connecting bracket 12. Under the action of an external force, when the temple 2 is opened relative to the frame 3, the elastic component 13 located between the support 11 and the connecting bracket 12 is deformed by the force. After the external force is removed, the elastic component 13 recovers its deformation, causing the temple 2 to retract inward relative to the frame 3. The provision of the elastic component 13 provides a damping force for the outward extension of the temple 2 relative to the frame 3, so that the temple 2 can share the pressure of the nose pad of the glasses, and makes the glasses 100 not easy to fall off when worn on the human body, thereby improving the wearing comfort.

[0066] In some embodiments of the present disclosure, the damping force provided by the elastic component 13 is related to the change in the rotation angle of the temple 2. Optionally, the damping force provided by the elastic component 13 may also be related to the change in the length of the elastic component 13. When the temple 2 rotates, the length of the elastic component 13 changes, thereby providing a restoring force for the temple 2 to rotate in the opposite direction. Optionally, the elastic component 13 has a variable opening angle, and the damping force provided by the elastic component 13 may also be related to the change in the opening angle of the elastic component 13. When the temple 2 rotates, the opening angle of the elastic component 13 changes, thereby providing a restoring force for the temple 2 to rotate in the opposite direction. Compared with an elastic component with a variable length, an elastic component with a variable opening angle can provide a greater damping force, thereby providing a greater clamping force to the temple 2 of the glasses 100.

[0067] In some embodiments of the present disclosure, the elastic component 13 is positioned between the second extension 114 and any of the stoppers 121 of the connecting bracket 12. This allows the second extension 114 to act on the elastic component, causing deformation of the elastic component 13, as the first extension 111 rotates away from the connecting bracket 12. For example, the second extension 114 can compress or stretch the elastic component 13, causing deformation or increasing the deformation of the elastic component 13. Thus, the elastic component 13 provides a restoring force that forces the first extension 111 to rotate toward the connecting bracket 12.

[0068] Exemplarily, the two limiting portions 121 of the connecting bracket 12 are arranged sequentially along the thickness direction of the frame 3 of the glasses 100. The two limiting portions 121 are respectively provided on the inner and outer sides. Optionally, when the temple 2 is extended, the second extension portion 114 can be used to compress the elastic component 13, so that the elastic component 13 provides a reverse return force. This can be achieved by positioning the elastic component 13 between the second extension portion 114 and the inner limiting portion 121. Alternatively, when the temple 2 is extended, the second extension portion 114 can be used to stretch the elastic component 13, so that the elastic component 13 provides a reverse return force. This can be achieved by positioning the elastic component 13 between the second extension portion 114 and the outer limiting portion 121.

[0069] It is understood that the "inner limit portion" mentioned above can be understood as the limit portion closer to the face when the glasses are worn, and the "outer limit portion" can be understood as the limit portion farther from the face when the glasses are worn.

[0070] Figures 11 to 13 show three different perspective views of the connection mechanism. The connection bracket 12 may include two connection arms 122. The two connection arms 122 and the limiting portion 121 form an accommodating space, and the second extension portion 114 is accommodated in the accommodating space.

[0071] In an optional embodiment, each connecting arm 122 is connected to two limiting portions 121. Optionally, the plane on which the connecting arms 122 lie is substantially perpendicular to the limiting portions 121. The two connecting arms 122 can be used to define the position of the second extension portion 114. The distance between the two connecting arms 122 is slightly greater than the width of the second extension portion 114, thereby cooperating with the two limiting portions 121 to limit the second extension portion 114 to swing only within the accommodation space.

[0072] In some embodiments of the present disclosure, the support 11 further includes a first rotating connection portion 113, which is connected to at least one of the two connecting arms 122. The connecting arms 122 also provide a physical structure for mounting the first rotating connection portion 113, thereby facilitating the connection between the connecting bracket 12 and the support 11.

[0073] In some optional embodiments, as shown in conjunction with Figures 6 and 10, the first rotating connection portion 113 may include a connecting shaft 1132, which is used to connect the support 11 and the connecting bracket 12, so that the temple can rotate relative to the frame about the connecting shaft 1132. The axial direction of the connecting shaft 1132 is the first axial direction. Optionally, the connecting shaft 1132 and the support 11 may be detachable separate parts; or the connecting shaft 1132 and the support 11 may be integrally formed.

[0074] In some optional embodiments, as shown in Figures 6 and 7, the first rotating connection portion 113 may include a connecting post 1131, which is disposed at the corner between the first extension portion 111 and the second extension portion 114. The connecting post 1131 has a post hole 1131a. A connecting shaft 1132 may be fixedly or rotatably connected to the post hole 1131a. The connecting arm 122 of the connecting bracket 12 may be provided with a first connecting hole 1221, and the connecting shaft 1132 plugs into the post hole 1131a and the first connecting hole 1221. This allows the connecting bracket 12 to be rotatably connected to the connecting shaft 1132.

[0075] Optionally, the connecting shaft 1132 may include a column and a cap disposed at one end of the column. The end of the column facing away from the cap sequentially passes through the first connecting hole 1221 on the upper connecting arm 122 and the post hole 1131a of the connecting column 1131, and then connects to the first connecting hole 1221 on the lower connecting arm 122. At least one of the first connecting hole 1221 and the post hole 1131a may be internally threaded, and the connecting shaft 1132 may be externally threaded. The column is threadedly connected to at least one of the first connecting hole 1221 and the post hole 1131a. The cap is positioned on the upper connecting arm 122. Positioning the connecting column 1131 at the angle between the first extension portion 111 and the second extension portion 114 reduces the space between the first extension portion 111 and the second extension portion 114, thereby not affecting the connection between the first extension portion 111 and the temple, nor interfering with the mating of the second extension portion 114 with the connecting bracket 12.

[0076] In some embodiments of the present disclosure, the support 11 may include a mounting plate connected to the first extension portion 111 and the second extension portion 114, with the mounting plate extending from the first extension portion 111 toward the second extension portion 114. A connecting post 1131 may be provided on the mounting plate. A post hole 1131a extends through both the connecting post 1131 and the mounting plate, allowing the connecting shaft 1132 of the first rotating connection portion 113 to pass through both the connecting post 1131 and the mounting plate. Optionally, the plane on which the mounting plate is located is substantially perpendicular to at least one of the planes on which the first extension portion 111 and the second extension portion 114 are located, and the mounting plate is connected to the ends of the first extension portion 111 and the second extension portion 114 on the same side.

[0077] In some embodiments of the present disclosure, two connecting arms 122 are disposed at an end of the connecting bracket 12 away from the frame. The plane on which the two connecting arms 122 lie is substantially perpendicular to the plane on which the second extension portion 114 lies, and the plane on which the two limiting portions 121 lie is substantially parallel to the plane on which the second extension portion 114 lies. A space for accommodating the second extension portion 114 is formed between the two connecting arms 122 and the two limiting portions 121.

[0078] Figure 8 shows a schematic diagram of the structure of a connection mechanism 1 using a spring sheet provided in some embodiments of the present disclosure. Figure 9 shows a schematic diagram of the structure of a spring sheet in a connection mechanism provided in some embodiments of the present disclosure. As shown in Figures 8 and 9, the elastic component 13 may include a bent spring sheet, and the bent portion of the spring sheet is sleeved on the connecting column 1131. Exemplarily, the bent spring sheet may be roughly U-shaped, having an outer convex arc sheet and two straight sheets located on both sides of the outer convex arc sheet. The connecting column 1131 may be located in the inner groove of the outer convex arc sheet, and the two straight sheets may respectively abut against the limiting portion 121 and the second extension portion 114.

[0079] Figure 7 shows a schematic diagram of a connection mechanism 1 employing a torsion spring, provided in some embodiments of the present disclosure. As shown in Figures 1 and 7, the elastic component 13 may include a torsion spring, which is sleeved around a connecting post 1131. The torsion spring comprises a helical barrel section and torsion arms located at either end of the helical barrel section. The helical barrel section sleeves around the connecting post 1131, with the two torsion arms located within the accommodation space and respectively abutting against the second extension 114 and the stopper 121.

[0080] In some optional embodiments, as shown in Figures 10 to 12, the second extension portion 114 includes a wide section 1141 and a narrow section 1142. The wide section 1141 is connected to the first extension portion 111, and the narrow section 1142 is connected to the end of the wide section 1141 facing away from the first extension portion 111. The width of the wide section 1141 is less than the distance between the two connecting arms 122. The width of the narrow section 1142 is less than the width of the wide section 1141. When the support 11 is rotated to the extreme position around the first axial direction, the narrow section 1142 stops at the limiting portion 121. The second extension portion 114 has a larger width on the side close to the first extension portion 111 and a smaller width on the end away from the first extension portion 111. The overall structural strength is good and it is not easy to produce large deformation. The free end of the second extension 114 has the greatest range of motion. By providing a narrow section 1142 on one side of the free end of the second extension 114, it facilitates the limited engagement with the stopper 121 and reduces frictional interference with other structures on the connecting bracket 12, such as the connecting arm 122, thereby improving reliability. The connecting bracket 12 can be made of a wear-resistant material, such as stainless steel.

[0081] In some optional embodiments, as shown in FIG. 10 to FIG. 12 , any one of the limiting portions 121 of the connecting bracket 12 is formed by a limiting member 121 a , and the limiting member 121 a is detachably connected to the connecting bracket 12 .

[0082] When assembling the support 11 and the connecting bracket 12, the second extension 114 can be placed in the accommodating space first, and then the limiting member 121a can be connected to the connecting bracket 12, with the free end of the second extension 114 limited in the accommodating space. Optionally, a connecting hole can be opened on the connecting bracket 12, a through hole can be opened in the limiting member 121a, and a fastener can be used to fix the limiting member 121a to the connecting hole of the connecting bracket 12. Optionally, there can be multiple connecting holes, and the multiple connecting holes extend along the arrangement direction of the two connecting arms 122. By making the limiting member 121a detachable, the assembly of the support 11 and the connecting bracket 12 can be facilitated. During long-term use, when the limiting member 121a is deformed or damaged, the limiting member 121a can be easily disassembled and replaced, thereby extending the service life of the entire connecting mechanism 1.

[0083] In some optional embodiments, in combination with Figures 6 and 14, the connecting mechanism 1 also includes a second rotating connecting portion 112 arranged on the first extension portion 111, and the second rotating connecting portion 112 is used to connect the temple and the first extension portion 111, so that the temple rotates around the second axis through the second rotating connecting portion 112, so that the temple can rotate around the second axis relative to the frame, and there is an angle between the second axis and the first axis.

[0084] In some possible implementations, as shown in FIG. 6 , an assembly portion 320 is provided at an end portion of the crossbeam 32 along the length direction. The assembly portion 320 is connected to the connecting bracket 12 and to the front frame 31 .

[0085] The mounting portion 320, at the end of the crossbeam 32, serves a dual purpose: it is used for both securing the temple 2 and attaching the front frame 31. A deformable gap is defined between the mounting portion 320 and the front frame 31, within which a deformable element 352 can be positioned. Optionally, two deformable elements 352 can be positioned between the mounting portion 320 and the front frame 31 at each end of the crossbeam 32. Each deformable element 352 is positioned sequentially along the height of the front frame and has a central hole. Each rigid connector passes through the mounting portion 320 and the corresponding central hole of the deformable element 352 to connect to the front frame.

[0086] Optionally, a through-hole can be provided in the assembly portion 320, extending along the thickness of the frame 3. A connecting post with a threaded groove is provided on the inner surface of the front frame 31. The rigid connector comprises a screw and a cap. The screw passes through the through-hole in the assembly portion 320 and is threadedly connected to the threaded groove of the connecting post on the front frame 31. The cap is retained on the assembly portion 320.

[0087] As shown in Figures 1 to 4 , the smart glasses 100 provided in the embodiments of the present disclosure include an optical imaging system 5. A crossbeam 32 supports the optical imaging system 5. The crossbeam 32 has a certain structural strength to ensure the positional accuracy of the optical imaging system 5. A communication hole is defined in the crossbeam 32, extending through the crossbeam 32 along the height of the frame 3. The optical imaging system 5 is located at the bottom of the crossbeam 32. One end of a fastener a passes through the communication hole in the crossbeam 32 and connects to the optical imaging system 5. Optionally, the smart glasses 100 may be augmented reality glasses.

[0088] In some possible embodiments, as shown in Figures 6 and 11, the assembly portion 320 includes a first connecting plate 321, which is provided with a notch 3211. The connecting bracket 12 has a second connecting plate 123, which is provided with a raised portion 1232. The notch 3211 cooperates with the raised portion 1232 to limit the position of the first and second connecting plates 123. The first and second connecting plates 321 and 123 can fit together along the thickness direction, and the raised portion 1232 can be inserted into the notch 3211. The notch 3211 and the raised portion 1232 cooperate to limit the position, so that the crossbeam 32 and the connecting bracket 12 are connected as a whole.

[0089] The second connecting plate 123 is detachably connected to the first connecting plate 321. For example, the first connecting plate 321 and the second connecting plate 123 can be connected and fixed by fasteners. The first connecting plate 321 can be provided with a notch 3211 and a plurality of first fixing holes 3212. Each of the first fixing holes 3212 is located on either side of the notch 3211. The second connecting plate 123 is provided with a plurality of second fixing holes 1231. Each fastener passes through the second fixing hole 1231 and connects to a corresponding first fixing hole 3212.

[0090] In some possible implementations, the assembly portion 320 of the smart glasses 100 further includes baffles 322. The baffles 322 are formed on both sides of the first connecting plate 321 along the thickness direction of the front frame 31. A retaining groove is formed between the baffles 322 and the first connecting plate 321, and the second connecting plate 123 is retained within the retaining groove. The baffles 322 are connected to the front frame 31.

[0091] Optionally, the thickness end surface of the second connecting plate 123 is in contact with the inner wall of the limiting groove, and the limiting groove defines the position of the second connecting plate 123 to prevent the second connecting plate 123 from shifting relative to the assembly portion 320. In addition to limiting the position of the connecting plate, the baffle 322 is also used to connect to the front frame 31.

[0092] In some possible embodiments, there is a deformation gap between the baffle 322 and the front frame 31, and the deformable element 352 can be arranged in the deformation gap. A through hole is opened on the baffle 322 along the thickness direction. The deformable element 352 can be set between the baffle 322 and the frame 3, and one end of the side connecting member 351 passes through the through hole and is connected to the front frame 31.

[0093] 1 and 4 , two deformable elements 352 may be provided between each assembly portion 320 and the front frame 31 . The deformable elements 352 are sequentially arranged along the height direction of the front frame. The deformable elements 352 have a center hole. The rigid connector sequentially passes through the baffle 322 and the center hole of the deformable element 352 to be connected to the front frame.

[0094] Figure 14 shows an exploded view of the connection structure of the temples and connecting mechanism in the glasses provided by an embodiment of the present disclosure; Figure 15 shows a partial structural diagram of the temples in the glasses provided by an embodiment of the present disclosure. As shown in Figures 14 and 15, in conjunction with Figure 2, the temples 2 of the glasses 100 can also swing up and down about a second axis relative to the frame 3. The free end of the temple 2 can swing up and down relative to the frame 3, which can accommodate wearers with different relative ear-eye heights, allowing the wearer's eyes to be located within the designed eye box, thereby allowing the wearer to see a complete and clear display image.

[0095] In some optional embodiments, the temples 2 of the glasses 100 can both expand outwards about a first axis relative to the frame 3 and swing up and down about a second axis relative to the frame 3. Optionally, the second axis is substantially perpendicular to the first axis.

[0096] In some optional embodiments, in combination with Figures 5, 6, 14 and 15, the connecting mechanism 1 also includes a second rotating connecting portion 112 arranged on the first extension portion 111, and the second rotating connecting portion 112 is used to rotatably connect the temple 2 and the first extension portion 111, so that the temple rotates around the second axis through the second rotating connecting portion 112, so that the temple can rotate around the second axis relative to the frame.

[0097] As shown in FIG1 , the first extension 111 is rotatably connected to the temple 2 via the second rotatable connection 112, allowing the temple 2 to swing up and down relative to the frame 3. As shown in FIG14 and FIG15 , the temple 2 is provided with a first toothed portion 21, with the protruding teeth of the first toothed portion 21 arranged sequentially along the width of the temple 2. The first extension 111 is provided with a second toothed portion 1111 that mates with the first toothed portion 21. When the temple 2 rotates relative to the first extension 111, the first toothed portion 21 is driven to move relative to the second toothed portion 1111, changing the position at which it meshes with the second toothed portion 1111.

[0098] In the embodiment of the present disclosure, the temples 2 can be moved in two different directions, that is, the two temples 2 of the glasses 100 can be stretched outward (bent outward) to adapt to the head circumference of different wearers and improve adaptability. Moreover, the two temples 2 of the glasses 100 can also swing up and down to achieve up and down adjustment to adapt to the relative height of the ears and eyes of different wearers, so that the eyes of different wearers can all be located within the designed eye box. The first tooth portion 21 and the second tooth portion 1111 each include a plurality of convex teeth. By adjusting the temple 2 up and down, the first tooth portion 21 and the second tooth portion 1111 can be engaged at different positions, thereby adjusting the up and down swinging gear of the temple 2. The second rotating connecting portion 112 may include a fastener 1121, a disc spring 1124, a friction plate 1123 and a second connecting hole 1122 provided on the first extension portion 111. One end of the fastener 1121 can pass through the disc spring 1124, the friction plate 1123, and the second connecting hole 1122 on the first extension part 111 in sequence and then be connected to the rotating column 22 on the temple 2. The arrangement of the disc spring 1124 and the friction plate 1123 provides damping for the up and down swinging of the temple 2.
