Description

Technical Field

[0001] This disclosure relates to the field of wearable device technology, and in particular to a smart pair of glasses. Background Technology

[0002] In related technologies, the frame of smart glasses typically includes a front frame, a support, and a back shell. The support is fixed between the front frame and the back shell, the front frame is connected to the back shell, the temples are connected to the back shell, and the camera is usually fixed to the support and extends from the front frame. Under external force, the deformation path caused by the temples expanding outward is back shell-front frame-support-camera, affecting the position and angular accuracy of the camera. The transmission of deformation can be reduced by designing the fixing methods of the back shell and front frame, back shell and support, or front frame and support. Summary of the Invention

[0004] 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, and there is a deformation gap between the crossbeam and the front frame. The temples are rotatably connected to the crossbeam, which can deform the crossbeam and move closer to the front frame.

[0009] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0010] To make the objectives, 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 with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0011] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0012] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0013] This disclosure provides some embodiments of eyeglasses, including a frame and temples. The temples are attached to the frame and are rotatable relative to the frame. Optionally, the temples can extend outward relative to the frame to make the eyeglasses suitable for wearers with different head circumferences.

[0014] In some optional embodiments, the glasses are smart glasses, and the smart glasses also include sensors 6. Optionally, the sensors 6 include sensors 6 capable of capturing at least one of position or attitude. For example, it could be a camera or an inertial measurement unit (IMU). The camera can acquire images required for SLAM (simultaneous localization and mapping) to provide vision-based tracking and localization, which can be used for localization of the smart glasses and recognition of interactive gestures. The inertial measurement unit can be used to provide motion data. Optionally, the sensors 6 can be mounted on the frame.

[0015] Figure 1 An exploded view of a partial structure of eyeglasses provided in some embodiments of this disclosure is shown. For example... Figure 1As shown, the eyeglasses 100 includes a frame 3 and temples 2, with the temples 2 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 exterior component of the eyeglasses 100 and can support the goggles; the front frame 31 is usually made of plastic and is prone to deformation. The temples 2 are rotatably connected to the crossbeam 32. When the temples 2 are extended outward, they cause a slight deformation of the crossbeam 32, causing the crossbeam 32 to move closer to the front frame 31.

[0016] If the front frame 31 is fixedly connected to the crossbeam 32 along its 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 leading to cracking of the front frame 31. By forming a deformation gap between the crossbeam 32 and the front frame 31, and by connecting the temples 2 only to the crossbeam 32 and not to the front frame, the front frame 31 will not deform when the crossbeam 32 deforms, reducing the impact of the deformation of the crossbeam 32 on the front frame 31.

[0017] Optionally, the frame 3 of the eyeglasses 100 also includes a rear frame. The front frame 31 and the rear frame are connected, and a receiving space is formed between them, with the crossbeam 32 disposed within the receiving space. It is understood that the terms "front frame" and "rear frame" do not imply a limitation on the positions of the two components, but are merely for the purpose of distinction. Those skilled in the art can set the components and their positions to implement the embodiments of this disclosure based on the working principle.

[0018] In some optional embodiments, the glasses 100 are smart glasses, including a sensor 6. The sensor 6 includes a sensor capable of capturing at least one of position or orientation. For example, it could be a camera or an inertial measurement unit. The sensor 6 can be positioned on the front frame 31 near the deformation gap. When the crossbeam 32 deforms, it does not substantially cause deformation at the location of the sensor 6 on the front frame 31, thereby ensuring that the position and orientation of the sensor 6 remain unchanged and do not affect the data collected by the sensor 6.

[0019] In some possible implementations, sensor 6 may include a camera positioned at both ends of the front frame 31. The ends of the crossbeam 32 may have deformation gaps with the front frame 31, minimizing the impact on the ends of the front frame 31 when the crossbeam 32 deforms. Sensor 6 can be positioned at both ends of the front frame 31. When the temple 2 extends outwards, the deformation at both ends of the crossbeam 32 is larger. Because the crossbeam 32 and the ends of the front frame 31 are not in direct contact, deformation at the ends of the crossbeam 32 will not cause contact interference with the ends of the front frame 31, preventing deformation of the front frame 31 and thus not affecting the position and attitude accuracy of the camera.

[0020] In some possible implementations, a camera hole 311 can be provided on the front frame, with the camera 6 located inside the front frame and covering the camera hole 311. The front frame serves to protect the camera 6. The front frame and the camera 6 can be connected and fixed using any of the following methods: adhesive structure, snap-fit ​​structure, and fastener connection structure.

[0021] In some possible implementations, the middle part of the front frame 31 and the crossbeam 32 are fixedly connected, and the sensor 6 is arranged at the end of the front frame 31; the smart glasses 100 also includes a cable that connects to the sensor 6, the cable extending along the inner wall of the front frame 31 from the end of the front frame 31 to the middle of the front frame 31, and extending to the crossbeam 32.

[0022] The cable segment located between the end 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 cable from moving when the crossbeam 32 deforms, thus affecting the camera 6.

[0023] In some possible implementations, the frame 3 includes a deformable element 352 located within a deformation gap, the deformable element 352 being positioned in a limiting engagement with at least one of the front frame 31 and the crossbeam 32.

[0024] The deformable element 352 can be an elastic element that can buffer external force when subjected to force and recover its deformation after the external force is removed. An elastic element can be, for example, a spring. The deformable element 352 can also be a flexible element that deforms when subjected to external force and recovers its deformation after the external force is removed. A flexible element can be, for example, a flexible washer or foam, which can buffer the impact of the deformation of the crossbeam 32 on the front frame 31. By placing the deformable element 352 within the deformation gap, the impact of the deformation of the crossbeam 32 on the deformation of the front frame 31 can be absorbed, reducing the deformation of the front frame 31 and allowing the sensor 6 to maintain a precise angle, thus improving the user experience.

[0025] It should be noted that the aforementioned deformable element 352 may only engage with the crossbeam 32 for limiting. Alternatively, the aforementioned deformable element 352 may only engage with the front frame 31 for limiting. Alternatively, the aforementioned deformable element 352 may engage with both the crossbeam 32 and the front frame 31 for limiting. Regarding "limiting," it can be understood as the deformable element 352 elastically abutting against at least one of the crossbeam 32 and the front frame 31 to achieve limiting through elastic abutment. It can also be understood as a specific limiting engagement structure being provided in the crossbeam 32 and the front frame 31, and the deformable element 352 being connected to this limiting engagement structure. The limiting engagement part limits the deformable element 352 to prevent it from falling off. The limiting engagement structure can be any of the following: a protrusion (e.g., a limiting post) and a groove. Of course, the limiting engagement structure can also be other structures, and this disclosure does not make a unique limitation.

[0026] In some possible embodiments, the frame 3 includes a deformable element 352 and a side connector 351. The side connector 351 is located at the end of the crossbeam 32 along its length and connects the crossbeam 32 and the front frame 31. The deformable element 352 is located on the side connector 351.

[0027] For example, the side connector 351 is at least partially located between the crossbeam 32 and the front frame 31, and the side connector 351 can be fixedly connected to the crossbeam 32 and the front frame 31 respectively by means of adhesive, snap-fit ​​or fastener connection.

[0028] For example, the side connector 351 can be made of a rigid material. For instance, 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 on the rigid connector. Optionally, the rigid connector can pass through the deformable element 352 and position it within the gap formed between the crossbeam 32 and the front frame 31. Optionally, the deformable element 352 can be, for example, a flexible washer or foam. The rigid connector can be, for example, a screw.

[0029] For example, at least two deformable elements 352 are provided at each end of the front frame 31. Each deformable element 352 at each end of the front frame 31 is arranged sequentially along the height direction of the front frame. Each deformable element 352 has a central hole. Each rigid connector passes through the crossbeam 32 and the central hole of the corresponding deformable element 352 in sequence and is connected to the front frame.

[0030] In some possible implementation schemes, combined Figure 1 and Figure 4 As shown, the frame 3 includes a central connector 34, which is located at the middle of the crossbeam 32 along its length and connects the crossbeam 32 and the front frame 31.

[0031] Optionally, the central connector 34 can be made of a rigid material. The center of the crossbeam 32 is furthest from the temples 2 at both ends, so rotation of the temples 2 has minimal impact on the center of the crossbeam 32. Therefore, the center of the crossbeam 32 and the front frame 31 can be connected and fixed using the central connector 34 made of a rigid material. By rigidly connecting the center of the front frame 31 and the crossbeam 32, significant relative vibration between the front frame 31 and the crossbeam 32 can be avoided, resulting in better integration between the front frame 31 and the crossbeam 32. The central connector 34 made of a rigid material can be a screw.

[0032] Optionally, the central connector 34 can also be made of a deformable material. Although the temples 2 are connected to the ends of the beam 32, when both temples 2 are folded inwards simultaneously, the middle of the beam 32 will inevitably deform to a certain extent, causing the beam 32 to cause the front frame 31 to deform to a certain degree. The central connector 34 is at least partially located between the front frame 31 and the beam 32, which can buffer and absorb the deformation of the beam 32 and reduce the impact of the beam 32 deformation on the front frame 31. The central connector 34 can be fixedly connected to the beam 32 and the front frame 31 by means of adhesive, snap-fit, or fastener connection.

[0033] Optionally, the central connector 34 can also be formed from a combination of rigid and deformable materials. For example, the central connector 34 may include a deformable element and a rigid connector. The deformable element may be disposed between the crossbeam and the front frame and on the rigid connector. For instance, the rigid connector may pass through the deformable element, the crossbeam, and the front frame to connect and fix the three together. The deformable element may be a flexible washer or foam. The rigid connector may be a screw.

[0034] Figure 5 This diagram illustrates the connection mechanism 1 of the eyeglasses 100 provided in some embodiments of the present disclosure, which connects the frame 3 and the temple 2. Figure 6 The following are exploded views of partial structures of the eyeglasses 100 provided in some embodiments of this disclosure, such as... Figure 5 , 6 As shown, the smart glasses 100 includes a frame 3, temples 2, and a connecting mechanism 1. The temples 2 are connected to the frame 3 via the connecting mechanism 1. The connecting 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.

[0035] In some alternative embodiments, such as Figure 5 , 6 As shown, 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 its length. The support 11 and the connecting bracket 12 are rotatably connected so that the temple 2 can rotate relative to the frame 3 about a first axis. The first axis can be the rotational axis of the temple 2 about the frame 3 as it unfolds outward. During the rotation of the temple 2 about the first axis, the temple 2 is opened.

[0036] In this embodiment, the support 11 is used to connect the temple 2, and the connecting bracket 12 is used to connect the frame 3, thereby achieving the connection between the temple and the 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, enabling adjustment of the angle between the temple 2 and the frame 3, allowing the glasses 100 to be suitable for wearers with different head circumferences. In some possible implementations, the sensor 6 and the connecting bracket 12 are positioned opposite each other along the thickness direction of the frame 3, and there is a deformation gap between the sensor 6 and the connecting bracket 12.

[0037] It is understandable that the thickness direction of the frame 3 refers to the direction perpendicular to the plane where the front frame 31 is located.

[0038] Optionally, the ends of the connecting bracket 12 and the crossbeam 32 can be fixedly connected using fasteners. There is a deformation gap between the sensor 6 located on the front frame 31 and the connecting bracket 12. During the opening of the temple 2, the connecting bracket 12 moves closer to the front frame 31 but does not contact the sensor 6.

[0039] In some possible implementation schemes, combined Figure 6 and Figure 10 As shown, the support 11 includes a first extension 111 and a second extension 114, which are connected to each other. Optionally, the first extension 111 and the second extension 114 may extend in different directions, that is, the first extension 111 and the second extension 114 may have an included angle. Alternatively, the first extension 111 and the second extension 114 may also extend along a curve, for example, the first extension 111 and the second extension 114 may extend along an arc.

[0040] In some embodiments of this disclosure, such as Figure 6 As shown, the connecting bracket 12 includes opposing limiting portions 121. The opposing limiting portions 121 can accommodate the second extension 114 and provide space for the second extension 114 to move. Optionally, two spaced-apart and opposing limiting portions 121 can be provided.

[0041] Optionally, the support 11 and the connecting bracket 12 are rotatably connected, and the second extension 114 of the support 11 is located between the opposing limiting portions 121. The second extension 114 can rotate about the first axis, and the opposing limiting portions 121 limit the range of relative rotation of the second extension 114. Thus, the range of relative rotation between the temple and the frame can be limited.

[0042] In some embodiments of this disclosure, the first axis can be the rotational axis of the temple 2 as it extends outward about the frame 3. When the second extension 114 of the connecting bracket 12 is confined to the limiting portion 121 on one side, there is a first angle between the temple 2 and the frame 3; when the second extension 114 is confined to the limiting portion 121 on the other side, there is a second angle between the temple 2 and the frame 3. Thus, the temple 2 and the frame 3 can rotate between the first angle and the second angle.

[0043] In some possible implementations, the extension direction of the first extension 111 is substantially parallel to the length direction of the temple 2, and the second extension 114, when abutting against one of the limiting portions 121, is substantially parallel to the length direction of the crossbeam 32. The first extension 111 and the second extension 114 are approximately perpendicular, and may also form an obtuse angle slightly greater than 90 degrees between them. The angle between the first extension 111 and the second extension 114 can be adapted to the required angle between the frame 3 and the temple 2 when the temple 2 is open. During the rotation of the first extension by the temple 2, the second extension 114 swings along the thickness direction of the frame 3, and the two limiting portions 121 limit the swing range of the second extension 114.

[0044] In some possible implementations, the second extension 114 deforms the beam 32 when it abuts against one of the limiting portions 121. The two limiting portions 121 are arranged sequentially along the thickness direction of the frame 3, one closer to the wearer and the other further away. When the temple 2 is opened, the second extension 114 abuts against the limiting portion 121 closer to the wearer, causing the beam 32 to deform towards the wearer's face. When the temple 2 is folded to its limit position, the second extension 114 abuts against the limiting portion 121 further away from the wearer, causing the beam 32 to deform towards the front of the wearer.

[0045] In some possible implementation schemes, combined Figure 6 and Figure 7 As shown, in some embodiments of this disclosure, an elastic member 13 may also be provided inside the connecting mechanism 1. The elastic force of the elastic member 13 can be used 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.

[0046] Optionally, the elastic member 13 provides a damping force to prevent the temples 2 from spreading outward relative to the frame 3. When the glasses are worn on the user's head, the two temples spread outward. The damping force provided by the elastic member 13 allows the two temples 2 to hold the user's head, thereby distributing the pressure of the nose pads and ensuring that the glasses are stably worn on the wearer's head.

[0047] In some embodiments of this disclosure, such as Figure 6As shown, the elastic member 13 is located between the support 11 and the connecting bracket 12, providing a restoring force for the first extension 111 to rotate closer to the connecting bracket 12. Under external force, as the temple 2 opens relative to the frame 3, the elastic member 13 located between the support 11 and the connecting bracket 12 deforms. After the external force is removed, the elastic member 13 returns to its original shape, causing the temple 2 to retract inwards towards the relative frame 3. The elastic member 13 provides damping force against the outward expansion of the temple 2 relative to the frame 3, allowing the temple 2 to share the pressure of the nose pads and making the glasses 100 less likely to fall off, thus improving wearing comfort.

[0048] In some embodiments of this disclosure, the damping force provided by the elastic member 13 is related to the change in the rotation angle of the temple 2. Optionally, the damping force provided by the elastic member 13 may also be related to the amount of change in the length of the elastic member 13. When the temple 2 rotates, the length of the elastic member 13 changes, thereby providing a restoring force to the temple 2 in the opposite direction. Optionally, the elastic member 13 has a variable angle, and the damping force provided by the elastic member 13 may also be related to the amount of change in the angle of the elastic member 13. When the temple 2 rotates, the angle of the elastic member 13 changes, thereby providing a restoring force to the temple 2 in the opposite direction. Compared to an elastic member with a variable length, an elastic member with a variable angle can provide a greater damping force, thereby providing a greater clamping force to the temple 2 of the eyeglasses 100.

[0049] In some embodiments of this disclosure, the elastic member 13 is located between the second extension 114 and any limiting portion 121 of the connecting bracket 12, such that when the first extension 111 rotates away from the connecting bracket 12, the second extension 114 acts on the elastic member to deform the elastic member 13. For example, the second extension 114 can compress or stretch the elastic member 13, causing deformation of the elastic member 13 or increasing the deformation of the elastic member 13. Thus, the elastic member 13 provides a restoring force to the first extension 111 as it rotates closer to the connecting bracket 12.

[0050] For example, the two limiting portions 121 of the connecting bracket 12 are arranged sequentially along the thickness direction of the frame 3 of the eyeglasses 100. The two limiting portions 121 are respectively provided on the inner side and the outer side. Optionally, when the temple 2 is extended outward, the elastic member 13 can be compressed by the second extension 114 so that the elastic member 13 provides a reverse restoring force. This can be achieved by placing the elastic member 13 between the second extension 114 and the inner limiting portion 121. Alternatively, when the temple 2 is extended outward, the elastic member 13 can be stretched by the second extension 114 so that the elastic member 13 provides a reverse restoring force. This can be achieved by placing the elastic member 13 between the second extension 114 and the outer limiting portion 121.

[0051] It is understandable that the "inner limiting part" mentioned above can be interpreted as the limiting part that is close to the face when the glasses are being worn, and the "outer limiting part" can be interpreted as the limiting part that is away from the face when the glasses are being worn.

[0052] Figures 11 to 13 Three different perspective views of the connecting mechanism are shown. The connecting bracket 12 may include two connecting arms 122, which and the limiting part 121 form a receiving space, and the second extension 114 is received within the receiving space.

[0053] In an optional embodiment, each connecting arm 122 is connected to two limiting portions 121. Optionally, the plane of the connecting arm 122 is substantially perpendicular to the limiting portions 121. The two connecting arms 122 can be used to define the position of the second extension 114, and the distance between the two connecting arms 122 is slightly greater than the width of the second extension 114, so that it can work with the two limiting portions 121 to limit the second extension 114 to swing only within the receiving space.

[0054] In some embodiments of this disclosure, the support 11 further includes a first rotary connection 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 rotary connection 113, facilitating the connection between the connecting bracket 12 and the support 11.

[0055] In some alternative embodiments, combined with Figure 6 and Figure 10 As shown, the first rotating connection 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 can be detachable separate parts; or, the connecting shaft 1132 and the support 11 can be integrally formed.

[0056] In some alternative embodiments, such as Figure 6 and Figure 7 As shown, the first rotary connecting portion 113 may include a connecting post 1131, which is disposed at the corner between the first extension 111 and the second extension 114, and has a post hole 1131a. A connecting shaft 1132 may be fixedly or rotatably connected to the post hole 1131a. A first connecting hole 1221 may be provided on the connecting arm 122 of the connecting bracket 12, and the connecting shaft 1132 is inserted into both the post hole 1131a and the first connecting hole 1221. Thus, the connecting bracket 12 can be rotatably connected to the connecting shaft 1132.

[0057] 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 passes sequentially through the first connecting hole 1221 on the upper connecting arm 122 and the post hole 1131a of the connecting shaft 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 provided with an internal thread, and the connecting shaft 1132 may be provided with an external thread. The column is threadedly connected to at least one of the first connecting hole 1221 and the post hole 1131a. The cap is confined to the upper connecting arm 122. Positioning the connecting shaft 1131 at the included angle of the first extension 111 and the second extension 114 occupies less space in the first extension 111 and the second extension 114, does not affect the connection between the first extension 111 and the first temple, and does not affect the cooperation between the second extension 114 and the connecting bracket 12.

[0058] In some embodiments of this disclosure, the support 11 may include a mounting plate connected to the first extension 111 and the second extension 114, the mounting plate extending from the first extension 111 to the second extension 114. A connecting post 1131 may be disposed on the mounting plate. A post hole 1131a passes through both the connecting post 1131 and the mounting plate, such that the connecting shaft 1132 of the first rotating connecting portion 113 passes through both the connecting post 1131 and the mounting plate. Optionally, the plane of the mounting plate is substantially perpendicular to at least one of the planes of the first extension 111 and the second extension 114, and the mounting plate is connected to the ends of the first extension 111 and the second extension 114 on the same side.

[0059] In some embodiments of this disclosure, two connecting arms 122 are disposed at the end of the connecting bracket 12 away from the frame. The planes on which the two connecting arms 122 are located are substantially perpendicular to the plane on which the second extension 114 is located, and the planes on which the two limiting portions 121 are located are substantially parallel to the plane on which the second extension 114 is located. A receiving space for accommodating the second extension 114 can be formed between the two connecting arms 122 and the two limiting portions 121.

[0060] Figure 8A schematic diagram of the structure of a connecting mechanism 1 employing a spring sheet is shown, according to some embodiments of the present disclosure. Figure 9 A schematic diagram of the structure of a spring in a connecting mechanism provided in some embodiments of this disclosure is shown. For example... Figure 8 and Figure 9 As shown, the elastic member 13 may include a bent spring sheet, the bent portion of which is sleeved on the connecting post 1131. Exemplarily, the bent spring sheet may be generally U-shaped, having an outwardly convex arc sheet and two straight pieces located on either side of the outwardly convex arc sheet. The connecting post 1131 may be located in the inner groove of the outwardly convex arc sheet, and the two straight pieces abut against the limiting portion 121 and the second extension 114, respectively.

[0061] Figure 7 A schematic diagram of the structure of a connection mechanism 1 employing a torsion spring, provided in some embodiments of this disclosure, is shown. For example... Figure 1 and Figure 7 As shown, the elastic member 13 may include a torsion spring, which is sleeved on the connecting post 1131. The torsion spring has a helical cylinder section and torsion arms located at both ends of the helical cylinder section. The helical cylinder section is sleeved on the connecting post 1131, and the two torsion arms are located within the receiving space and respectively abut against the second extension 114 and the limiting part 121.

[0062] In some alternative embodiments, combined with Figures 10 to 12 As shown, the second extension 114 includes a wide section 1141 and a narrow section 1142. The wide section 1141 is connected to the first extension 111, and the narrow section 1142 is connected to the end of the wide section 1141 that faces away from the first extension 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 its limit position around the first axis, the narrow section 1142 abuts against the limiting part 121. The second extension 114 has a larger width on the side closer to the first extension 111 and a smaller width on the side farther from the first extension 111, resulting in good overall structural strength and making it less prone to large deformation. The free end of the second extension 114 has the largest range of motion. By providing a narrow section 1142 on one side of the free end of the second extension 114, it facilitates the limiting cooperation with the limiting part 121, reduces frictional interference with other structures on the connecting bracket 12 such as the connecting arm 122, and improves reliability. The connecting bracket 12 can be made of a wear-resistant material, for example, stainless steel.

[0063] In some alternative embodiments, combined with Figures 10 to 12 As shown, any one of the limiting portions 121 of the connecting bracket 12 is formed by a limiting member 121a, and the limiting member 121a is detachably connected to the connecting bracket 12.

[0064] When assembling the support 11 and the connecting bracket 12, the second extension 114 can be placed in the receiving 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 confined within the receiving space. Optionally, a connecting hole can be opened on the connecting bracket 12, and a through hole can be opened on the limiting member 121a, and the limiting member 121a can be fixedly connected to the connecting hole of the connecting bracket 12 using fasteners. Optionally, there can be multiple connecting holes, which 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 becomes deformed or damaged, it can be easily disassembled and replaced, thereby extending the service life of the entire connecting mechanism 1.

[0065] In some alternative embodiments, combined with Figure 6 and Figure 14 As shown, the connecting mechanism 1 further includes a second rotating connecting part 112 disposed on the first extension 111. The second rotating connecting part 112 is used to connect the temple and the first extension 111, so that the temple can rotate about the second axis through the second rotating connecting part 112, so that the temple can rotate about the second axis relative to the frame. The second axis has an angle with the first axis.

[0066] See some possible implementations. Figure 6 As shown, the end of the crossbeam 32 along the length direction is provided with an assembly part 320, which is connected to the connecting bracket 12 and to the front frame 31.

[0067] The assembly part 320 is the end of the crossbeam 32 and has a dual function: it can be used to connect and fix to the temple 2, and also to connect and assemble with the front frame 31. A deformation gap exists between the assembly part 320 and the front frame 31, and deformable elements 352 can be disposed within this gap. Optionally, two deformable elements 352 can be disposed between the assembly part 320 and the front frame 31 at each end of the crossbeam 32. Each deformable element 352 is arranged sequentially along the height direction of the front frame, and each deformable element 352 has a central hole. Each rigid connector passes sequentially through the assembly part 320 and the central hole of the corresponding deformable element 352 to connect to the front frame.

[0068] Optionally, a through hole may be provided in the mounting part 320, extending along the thickness direction 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 has a screw and a cap. The screw passes through the through hole of the mounting part 320 and is threaded into the threaded groove of the connecting post on the front frame 31, while the cap is confined to the mounting part 320.

[0069] Combination Figures 1 to 4As shown, the smart glasses 100 provided in this embodiment of the present disclosure has an optical imaging system 5. A crossbeam 32 supports the optical imaging system 5 and has sufficient structural strength to ensure the positional accuracy of the optical imaging system 5. A connecting hole is provided on the crossbeam 32, extending through the crossbeam 32 along the height direction of the frame 3. The optical imaging system 5 is located at the bottom of the crossbeam 32, and one end of a fastener a passes through the connecting hole on the crossbeam 32 and is connected to the optical imaging system 5. Optionally, the smart glasses 100 can be augmented reality glasses.

[0070] See some possible implementations. Figure 6 and Figure 11 As shown, the assembly part 320 includes a first connecting plate 321 with a notch 3211. The connecting bracket 12 has a second connecting plate 123 with a protrusion 1232. The notch 3211 and the protrusion 1232 cooperate to limit the first and second connecting plates 123. The first and second connecting plates 321 and 123 can fit together along their thickness direction, and the protrusion 1232 can be inserted into the notch 3211. The limiting cooperation between the notch 3211 and the protrusion 1232 makes the crossbeam 32 and the connecting bracket 12 connected as a single unit.

[0071] 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 may have a notch 3211 and a plurality of first fixing holes 3212. Each of the first fixing holes 3212 is located on both sides of the notch 3211. The second connecting plate 123 has a plurality of second fixing holes 1231. Each fastener passes through a second fixing hole 1231 and is connected to a corresponding first fixing hole 3212.

[0072] In some possible implementations, the assembly portion 320 of the smart glasses 100 further includes a baffle 322. The baffle 322 is formed on both sides of the first connecting plate 321 along the thickness direction of the front frame 31, and a limiting groove is formed between the baffle 322 and the first connecting plate 321, with the second connecting plate 123 confined within the limiting groove. The baffle 322 is connected to the front frame 31.

[0073] Optionally, the thick end face of the second connecting plate 123 fits into the inner wall of the limiting groove, which limits the position of the second connecting plate 123 and prevents it from shifting relative to the assembly part 320. In addition to limiting the position of the connecting plate, the baffle 322 is also used to connect with the front frame 31.

[0074] In some possible implementations, there is a deformation gap between the baffle 322 and the front frame 31, and the deformable element 352 can be disposed in the deformation gap. A through hole is provided on the baffle 322 along the thickness direction. The deformable element 352 can be disposed between the baffle 322 and the mirror frame 3. One end of the side connector 351 passes through the through hole and is connected to the front frame 31.

[0075] See Figure 1 and Figure 4 As shown, two deformable elements 352 can be provided between each assembly part 320 and the front frame 31. Each deformable element 352 is arranged sequentially along the height direction of the front frame. Each deformable element 352 has a central hole. The rigid connector passes through the baffle 322 and the central hole of the deformable element 352 in sequence and is connected to the front frame.

[0076] Figure 14 An exploded view of the connection structure between the temple and the connecting mechanism in the eyeglasses provided in an embodiment of this disclosure is shown. Figure 15 A partial structural diagram of the temples of eyeglasses provided in an embodiment of this disclosure is shown. For example... Figure 14 , Figure 15 As shown, combined with Figure 2 The temples 2 of the eyeglasses 100 can also swing up and down relative to the frame 3 around a second axis. The free end of the temple 2 can swing up and down relative to the frame 3, accommodating wearers with different relative ear-eye heights, allowing the wearer's eyes to be positioned within the designed eye box, thus enabling the wearer to see a complete and clear display image.

[0077] In some optional embodiments, the temples 2 of the eyeglasses 100 can both extend outward relative to the frame 3 about a first axis and swing up and down relative to the frame about a second axis. Optionally, the second axis is substantially perpendicular to the first axis.

[0078] In some alternative embodiments, combined with Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, the connecting mechanism 1 further includes a second rotating connecting part 112 disposed on the first extension 111. The second rotating connecting part 112 is used to rotatably connect the temple 2 and the first extension 111, so that the temple can rotate about the second axis through the second rotating connecting part 112, so that the temple can rotate about the second axis relative to the frame.

[0079] See Figure 1 As shown, the first extension 111 is rotatably connected to the temple 2 via the second rotating connection 112, allowing the temple 2 to swing up and down relative to the frame 3. Figure 14 , 15As shown, the temple 2 is provided with a first tooth 21, and each tooth of the first tooth 21 is arranged sequentially along the width direction of the temple 2. The first extension 111 is provided with a second tooth 1111 that is adapted to the first tooth 21. When the temple 2 rotates relative to the first extension 111, it can drive the first tooth 21 to move relative to the second tooth 1111, changing the position of meshing with the second tooth 1111.

[0080] In this embodiment, the temples 2 can move in two different directions, that is, the two temples 2 of the glasses 100 can be opened outward (bent outward) to adapt to different head circumferences of wearers and improve fit. Furthermore, the two temples 2 of the glasses 100 can also swing up and down to adjust to accommodate the relative height of the ears and eyes of different wearers, ensuring that the eyes of different wearers are within the designed eye box range. The first tooth 21 and the second tooth 1111 both include multiple protruding teeth. By adjusting the temples 2 up and down, the first tooth 21 and the second tooth 1111 can engage at different positions to adjust the up and down swing position of the temples 2. The second rotating connection part 112 may include a fastener 1121, a disc spring 1124, a friction plate 1123, and a second connecting hole 1122 disposed on the first extension part 111. The fastener 1121 can pass through the disc spring 1124, the friction plate 1123, and the second connecting hole 1122 on the first extension 111 in sequence and then connect to the rotating column 22 on the temple 2. The disc spring 1124 and the friction plate 1123 provide damping for the temple 2 to swing up and down.
