Hinge mechanism, frame, eyewear and smartglasses

Abstract

This application provides a pivot mechanism, including a first bracket for connecting to a frame, a second bracket for connecting to the temples, a pivot, and a damping element. The first bracket includes a first connecting portion with a slot, and the second bracket has a second connecting portion. The pivot passes through the first and second connecting portions, allowing the second bracket to rotate relative to the first bracket. The damping element is disposed within the slot; when the second bracket rotates relative to the first bracket, it slides within the slot. When the second bracket rotates relative to the first bracket, it rotates the damping element. Due to friction between the damping element and the inner wall of the slot, a damping effect is created, allowing the second bracket connected to the damping element to maintain a suspended posture and maintain good suspension performance at any angle, adapting to different users' wearing styles. Furthermore, this application also provides frames, eyeglasses, and smart glasses.

Description

Technical Field

[0001] This application relates to the field of consumer electronics, specifically to a hinge mechanism, a frame, eyeglasses, and smart glasses. Background Technology

[0002] Currently, eyeglasses have become an essential item for some people, especially those with nearsightedness. With advancements in technology, smart glasses have emerged beyond traditional eyeglasses. These smart glasses utilize an optical engine to project image information onto the lenses or a dedicated display screen, thus achieving intelligent functionality.

[0003] In order to facilitate storage, eyeglasses in related technologies usually have a hinge mechanism on the frame, which allows the temples of the glasses to be folded up for storage and rotated to the angle required by the user. Since different users have different head shapes, head circumferences, pupillary distances, etc., the rotation angle when wearing them will be different. The hinge mechanism needs to be able to remain suspended at any rotation angle to adapt to the wearing needs of different users. Summary of the Invention

[0004] This application provides a pivot mechanism, a frame, eyeglasses, and smart glasses, which can improve the above-mentioned technical problems and adapt to different users.

[0005] In a first aspect, embodiments of this application provide a pivot mechanism suitable for use in eyeglasses. The eyeglasses include a frame and temples. The pivot mechanism includes a first bracket for connecting to the frame, a second bracket for connecting to the temples, a pivot, and a damping member. The first bracket includes a first connecting portion with a slot, and the second bracket has a second connecting portion. The pivot passes through the first and second connecting portions to allow the second bracket to rotate relative to the first bracket. The damping member is slidably disposed within the slot and is connected to the second bracket. When the second bracket rotates relative to the first bracket, it causes the damping member to slide within the slot.

[0006] Secondly, embodiments of this application also provide a glasses frame, including a frame, temples, and the aforementioned pivot mechanism, with a first connecting part connected to the frame and a third connecting part connected to the temples.

[0007] Thirdly, embodiments of this application also provide eyeglasses, including the aforementioned frame and lenses, with the lenses mounted on the frame.

[0008] Fourthly, this application also provides a smart glasses, including the aforementioned frame, display unit, optical engine, and flexible circuit board. The display unit is disposed on the frame, the optical engine is disposed on the temple, one end of the flexible circuit board is electrically connected to the optical engine, and the other end runs along the temple and the pivot mechanism, and extends to the frame and is electrically connected to the display unit.

[0009] The rotating mechanism provided in this application embodiment can be applied to eyeglass frames, eyeglasses, or smart glasses. By setting a slot on the first bracket, a damping element is placed in the slot and connected to the second bracket. When the second bracket rotates relative to the first bracket, it will drive the damping element to rotate. Due to the friction between the damping element and the inner wall of the slot, a damping effect is formed on the damping element, so that the second bracket connected to the damping element can maintain a suspended posture and maintain a good suspension effect at any angle, adapting to the wearing of different users.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] In related technologies, eyeglasses typically incorporate a hinge mechanism in the frame for easy storage. This allows the temples to fold down for storage and rotate to the desired angle for the user. However, due to differences in head shape, head circumference, and interpupillary distance among users, the rotation angle will vary. Therefore, the hinge mechanism needs to remain suspended at any rotation angle to accommodate different users' wearing needs. Based on this, the inventors of this application have proposed hinge mechanisms, eyeglass frames, eyeglasses, and smart glasses according to various embodiments of this application, aiming to improve the aforementioned deficiencies and enhance the applicability of eyeglass frames. The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] See Figure 1 This embodiment provides a pair of eyeglasses 10, which includes a frame 30 and lenses 20. The lenses 20 can be mounted on the frame 30. The lenses 20 can be various types of lenses, such as plano lenses, myopia lenses, presbyopia lenses, filter lenses, and colored lenses, and are not limited here. The lenses 20 can be made of materials such as glass and resin, and are not limited here. In some other embodiments, the lenses 20 may not be provided, in which case the eyeglasses 10 can simply serve as a decorative accessory for the user.

[0027] The frame 30 includes temples 50, a frame 40, and a hinge mechanism 100. The frame 40 is used to mount the lenses 20, and the temples 50 are connected to the frame 40 and used for wearing by the user. It should be noted that the frame 40 and temples 50 can be made of various materials such as metal, plastic, and ceramic; no limitation is made here. The frame 40 may include two independent frame structures for mounting two separate lenses 20, corresponding to the user's left and right eyes respectively.

[0028] There can be two temples 50, which are respectively located on opposite sides of the frame 40 and connected to the frame 40. The two temples 50 are arranged in a roughly symmetrical structure and are hinged to the frame 40 by a pivot mechanism 100 for easy storage of the temples 50. Specifically, the frame 40 is provided with an extension 41, which is bent relative to the frame 40. The pivot mechanism 100 is located at the end of the extension 41 away from the frame 40. The temple 50 is connected to the pivot mechanism 100, and the end of the temple 50 away from the pivot mechanism 100 is bent to form an ear hook 55, which is suitable for hanging on the user's ear.

[0029] Specifically, in this embodiment, please refer to the following: Figure 2 and Figure 3 The extension 41 forms a first internal cavity 42, and the temple 50 forms a second internal cavity 51. The second internal cavity 51 is located at the end of the temple 50 near the extension 41. The first internal cavity 42 and the second internal cavity 51 are used to assemble the rotating shaft mechanism 100, thereby covering the rotating shaft mechanism 100 and improving the aesthetics of the frame 30.

[0030] See Figure 4 The rotating mechanism 100 includes a first bracket 110, a second bracket 150, a rotating shaft 190, and a damping element 170. The first bracket 110 is used to connect the frame 40, and the second bracket 150 is used to connect the temple 50. The first bracket 110 and the second bracket 150 are rotatably connected via the rotating shaft 190, allowing the second bracket 150 to rotate relative to the first bracket 110. Specifically, the first bracket 110 can at least partially extend into the first internal cavity 42 and is fixed to the frame 40 by means of adhesive, screws, or other methods. The second bracket 150 can at least partially extend into the second internal cavity 51 and is fixed to the temple 50 by means of adhesive, screws, or other methods. The damping element 170 is disposed within the first bracket 110 and connected to the second bracket 150, providing damping during the rotation of the second bracket 150 relative to the first bracket 110, allowing the second bracket 150 to remain suspended during rotation relative to the first bracket 110.

[0031] For details in this embodiment, please refer to the following: Figure 4 and Figure 5The first support 110 includes a guide plate 111 and two first connecting portions 112 disposed at both ends of the guide plate 111. Each first connecting portion 112 has a first shaft hole 113 extending through the first connecting portion 112, and the first shaft holes 113 of the two first connecting portions 112 are coaxially arranged. The first connecting portion 112 is used to mount a rotating shaft 190. The two first connecting portions 112 are symmetrically distributed relative to the guide plate 111. The guide plate 111 is used to cooperate with the second support 150 to form a guide, so that the second support 150 maintains a predetermined trajectory during rotation relative to the first support 110. In this embodiment, the guide plate 111 is configured as an arc, and the two first connecting portions 112 are located on the inner side of the guide plate 111.

[0032] In one embodiment, the two first connecting portions 112 can be configured to extend into the first internal cavity 42, so that when installed on the frame 40, the two first connecting portions 112 can be embedded in the first internal cavity 42, thereby shielding the first support 110 and improving the aesthetic appearance of the frame. The two first connecting portions 112 are spaced 165 apart, thus forming an installation space between them.

[0033] Please refer to it again. Figure 5Each first connecting portion 112 is provided with a slot 114 for mounting a damping element 170. In this embodiment, the slot 114 has an opening 115, the opening direction of which faces the extension direction of the guide plate 111, that is, the opening direction of the slot 114 faces the direction of the second bracket 150. Specifically, in this embodiment, the first connecting portion 112 includes a bottom wall 1141, a first side wall 1142, and a second side wall 1143 forming the slot 114. The first side wall 1142 and the second side wall 1143 are arranged opposite to each other and connected to opposite sides of the bottom wall 1141. The first side wall 1142 and the second side wall 1143 are both approximately perpendicular to the bottom wall 1141. An opening 115 is formed between one end of the first sidewall 1142 away from the bottom wall 1141 and one end of the second sidewall 1143 away from the bottom wall 1141. A first shaft hole 113 penetrates the first sidewall 1142 and the second sidewall 1143, and the axial direction of the first shaft hole 113 is approximately perpendicular to the first sidewall 1142 and the second sidewall 1143. A mounting opening 116 is provided at one end of the slot 114, which allows the damping element 170 to be embedded in the slot 114. In this embodiment, the mounting opening 116 is located at the end of the slot 114 near the first shaft hole 113. In order to limit the movement of the damping member 170, the first connecting part 112 may also include a third side wall 1144 forming a slot 114. The third side wall 1144 is connected to the bottom wall 1141, the first side wall 1142 and the second side wall 1143, and the third side wall 1144 is generally perpendicular to the first side wall 1142 and the second side wall 1143. The third side wall 1144 is opposite to the assembly opening 116.

[0034] To facilitate the subsequent installation of the damping element 170, a first protrusion 117 is provided on the side of the first sidewall 1142 facing the second sidewall 1143. The first protrusion 117 is located at the end of the first sidewall 1142 away from the bottom wall 1141. A second protrusion 118 is provided on the side of the second sidewall 1143 facing the first sidewall 1142. The second protrusion 118 is located at the end of the second sidewall 1143 away from the bottom wall 1141. That is, both the first protrusion 117 and the second protrusion 118 are provided at the opening 115, and the first protrusion 117 and the second protrusion 118 are arranged opposite each other and spaced 165 degrees apart. By providing the first protrusion 117 and the second protrusion 118, the inner diameter of the opening 115 is reduced, which can prevent the damping element 170 embedded in the slot 114 from falling out of the opening 115.

[0035] It is understood that the two first connecting parts 112 can have the same structure. Providing two first connecting parts 112 can enhance the stability of the first support 110 and the second support 150 during the connection process. In some other embodiments, only one first connecting part 112 may be provided; this embodiment does not limit this.

[0036] Please refer to the following: Figure 4 and Figure 6 The second bracket 150 is used to connect with the temple 50 and can rotate relative to the first bracket 110. The second bracket 150 is provided with a second connecting part 155, which can be embedded between two first connecting parts 112. The second connecting part 155 has a second shaft hole 156, which can be coaxially arranged with the first shaft holes 113 of the first connecting parts 112 on both sides of the second connecting part 155. The rotating shaft 190 passes through the first shaft hole 113 and the second shaft hole 156, so that the second bracket 150 can rotate relative to the first bracket 110.

[0037] For details, please continue reading Figure 6 In this embodiment, the second bracket 150 includes an arc-shaped plate 151, a first cover plate 152, a second cover plate 153, a second connecting portion 155, and a third connecting portion 160. The first cover plate 152 and the second cover plate 153 are disposed opposite to each other and connected to the edge of the arc-shaped plate 151. In one embodiment, the second connecting portion 155 can be directly connected to the inner side of the arc-shaped plate 151 and located between the first cover plate 152 and the second cover plate 153. During assembly, the first bracket 110 is disposed between the first cover plate 152 and the second cover plate 153, and the two first connecting portions 112 are respectively adjacent to the first cover plate 152 and the second cover plate 153. The first cover plate 152 and the second cover plate 153 can shield the first connecting portions 112, thereby improving the appearance of the rotating shaft mechanism 100.

[0038] The spacing between the second connecting portion 155 and the first cover plate 152, and the spacing between the second connecting portion 155 and the second cover plate 153, are approximately equal to the thickness of the first connecting portion 112. This allows the first connecting portion 112 to be easily inserted between the second connecting portion 155 and the first cover plate 152 / second cover plate 153, while maintaining structural compactness. Simultaneously, the spacing between the two first connecting portions 112 is approximately equal to the spacing between the second connecting portions 155, allowing the second connecting portion 155 to be easily inserted between the two first connecting portions 112, while maintaining structural compactness.

[0039] In a more specific embodiment, both the first cover plate 152 and the second cover plate 153 can be approximately arc-shaped, and their curvature is consistent with that of the arc-shaped plate 151. The first cover plate 152 and the second cover plate 153 can be completely opposite each other and symmetrically distributed on opposite sides of the arc-shaped plate 151. The guide plate 111 can fit against the arc-shaped plate 151, and during the rotation of the second support 150 relative to the first support 110, it always slides against the inner side of the arc-shaped plate 151, thereby playing a guiding role. The curvature of the guide plate 111 can be configured to match the curvature of the arc-shaped plate 151. Furthermore, the first connecting portion 112 can also be provided with a step, and the first cover plate 152 and the second cover plate 153 can be respectively embedded in the step of the two first connecting portions 112. By providing the step, the second support 150 can be guided, improving the stability of the second support 150 when rotating relative to the first support 110.

[0040] The third connecting part 160 is connected to the arc-shaped plate 151 and is used to connect with the damping member 170. During the rotation of the second bracket 150 relative to the first bracket 110, the damping member 170 is driven to slide within the slot 114. In this embodiment, the second connecting part 155 is connected to the third connecting part 160, thereby forming a fixed connection relative to the arc-shaped plate 151.

[0041] In this embodiment, the damping member 170 is slidably disposed in the slot 114 and is connected to the third connecting part 160. When the damping member 170 slides in the slot 114, it will slide and rub against the wall surrounding the slot 114 (i.e., at least one of the aforementioned bottom wall 1141, first side wall 1142, and second side wall 1143), thereby generating a damping force. This prevents the second bracket 150 from rotating relative to the first bracket 110 on its own. Only when driven by an external force and overcoming the frictional resistance between the damping member 170 and the wall surrounding the slot 114 can the damping member 170 slide relative to the slot 114, and then the second bracket 150 can rotate relative to the first bracket 110. In this way, the second bracket 150 can be suspended at any angle relative to the first bracket 110 during the rotation process.

[0042] The damping element 170 can extend directly from the opening 115 into the slot 114 and connect to the third connecting part 160. Please refer to the following in this embodiment: Figure 4 and Figure 7The rotating shaft mechanism 100 may further include a crank 180 and a pivot 185. One end of the crank 180 is rotatably connected to a damping element 170, and the other end is rotatably connected to a third connecting portion 160 of the second bracket 150. By configuring the crank 180, when the second bracket 150 rotates relative to the first bracket 110, the crank 180 is driven to move, causing the damping element 170 to slide along the extending direction of the slot 114. Since the crank 180, the damping element 170, and the third connecting portion 160 are all rotatably connected, interference is less likely to occur during the rotation of the second bracket 150 relative to the first bracket 110, resulting in a smoother rotation process.

[0043] Specifically, such as Figure 7 As shown, the crank 180 has a first through hole 181 and a second through hole 182. Both the first through hole 181 and the second through hole 182 pass through the crank 180. The first through hole 181 and the second through hole 182 are located at both ends of the crank 180 along its length, and the axial direction of the first through hole 181 and the axial direction of the second through hole 182 are approximately parallel to each other. The damping element 170 includes a connecting post 171 and opposing first damping blocks 172 and second damping blocks 173. The connecting post 171 is connected between the first damping blocks 172 and the second damping blocks 173, and the cross-sectional area of ​​the first damping blocks 172 and the second damping blocks 173 is larger than the cross-sectional area of ​​the connecting post 171. At the same time, the cross-sectional area of ​​the first damping blocks 172 and the second damping blocks 173 is larger than the cross-sectional area of ​​the first through hole 181. The connecting post 171 is sleeved in the first through hole 181 of the crank 180 and can rotate relative to the crank 180. The first damping blocks 172 and the second damping blocks 173 are located outside the crank 180 and on opposite sides of the crank 180, so that the damping element 170 cannot come off the crank 180.

[0044] Pivot 185 can be inserted into the second through hole 182 and rotatably connected to the third connecting part 160, so that crank 180 can also rotate relative to the second bracket 150. During the rotation of the second bracket 150 relative to the first bracket 110, the second bracket 150 can rotate relative to the crank 180, and the crank 180 is subjected to the traction force of the second bracket 150, which will drive the damping element 170 to slide in the slot 114.

[0045] The first damping block 172 and the second damping block 173 are fitted against the wall forming the slot 114. Specifically, the first damping block 172 is fitted against the first side wall 1142, and the second damping block 173 is fitted against the second side wall 1143. The first damping block 172 is limited by the first protrusion 117, and the second damping block 173 is limited by the second damping block 173, so the damping member 170 will not come out of the opening 115. In the assembled state, since the rotating shaft 190 passes through the first shaft hole 113, the rotating shaft 190 is adjacent to the assembly opening 116. Due to the obstruction of the rotating shaft 190, the damping member 170 will not come out of the assembly opening 116, thereby limiting the damping member 170.

[0046] It should be noted that the first damping block 172 and the first sidewall 1142 are in hard contact with each other when they are fitted together, that is, the first damping block 172 exerts pressure on the first sidewall 1142, so that friction can be generated between the two when the first damping block 172 slides relative to the first sidewall 1142. Similarly, the second damping block 173 and the second sidewall 1143 are in hard contact with each other when they are fitted together, that is, the second damping block 173 exerts pressure on the second sidewall 1143, so that friction can be generated between the two when the second damping block 173 slides relative to the second sidewall 1143. The first damping block 172 and the second damping block 173 can be made of materials such as metal and plastic, and this embodiment is not limited to this. In some other embodiments, only the first damping block 172 or the second damping block 173 may be provided, and the damping member 170 may also take other forms, as long as it is ensured that the damping member 170 can generate sliding friction with the wall forming the slot 114.

[0047] To increase the friction between the damping element 170 and the wall forming the groove 114, the first sidewall 1142 and the second sidewall 1143 can be made into rough planes to enhance friction. In one embodiment, the surfaces of the first damping block 172 and / or the second damping block 173 that contact the first sidewall 1142 or the second sidewall 1143 can be provided with matching interlocking patterns. These interlocking patterns can be, for example, wavy and extend along the extension direction of the groove 114. By providing these interlocking patterns, the contact area between the damping element 170 and the wall forming the groove 114 can be increased, improving friction. Simultaneously, these patterns can also guide the sliding of the damping element 170.

[0048] In this embodiment, there are two damping elements 170, which are respectively disposed in the slots 114 of the two first connecting parts 112. Similarly, there are two cranks 180, which are respectively connected to one damping element 170 and extend out of the opening 115 of the slot 114 to be rotatably connected to the third connecting part 160 of the second bracket 150.

[0049] In this embodiment, please refer again. Figure 6 To facilitate the assembly of the crank 180, the third connecting portion 160 includes a body 161 and a first end 162 and a second end 163 connected to both ends of the body 161. The first end 162 and the second end 163 are connected to the arc-shaped plate 151, and the second connecting portion 155 is connected to the body 161. The first end 162 and the second end 163 have mounting grooves 164 facing the first bracket 110. Simultaneously, the second end 162 and the third end 163 also have mounting holes 166. The axial direction of the mounting holes 166 is consistent with the axial direction of the pivot 185 and is approximately parallel to the axial direction of the first shaft hole 113 and the second shaft hole 156. Furthermore, the mounting hole 166 in the first end 162 can penetrate the first end 162, and the mounting hole 166 in the third end 163 can penetrate the second end 163. One end of the crank 180 with the second through hole 182 is embedded in the mounting groove 164. The pivot 185 passes through the mounting hole 166 of the first end 162 or the second end 163 and is inserted into the second through hole 183 to form a connection, so that the crank 180 can rotate relative to the second bracket 150 and can be driven by the second bracket 150 to move, thereby driving the damping element 170 to move.

[0050] During the rotation of the second support 150 relative to the first support 110, there are two states: one is the unfolded state of the frame relative to the lens frame 40 (e.g., Figure 8 As shown), one is the frame folded relative to the frame at a 40° angle (inward folding state, as shown). Figure 9 (As shown). In this embodiment, refer to... Figure 10 When the temple 50 is in the unfolded state relative to the frame, the damping element 170 is located at the end near the third side wall 1144. Referring to Figure 11, when the temple 50 is folded relative to the frame 40, the second bracket 150 rotates relative to the first bracket 110. At this time, the damping element 170 slides along the slot 114 under the action of the crank 180 and the second bracket 150, and slides towards the mounting opening 116, and finally approaches the mounting opening 116.

[0051] When the temple 50 is in the extended state relative to the frame, different users may experience different head shapes. For people with large heads, the temple 50 may be stretched open and folded outward relative to the frame. If the second support 150 is left with a large outward folding angle during this process, people with small heads may find that the temple 50 cannot properly hold their head, causing the frame to easily fall off. Therefore, in this embodiment, please refer to... Figure 10 and Figure 11The rotating mechanism 100 may also include an elastic element 195, which is disposed in the slot 114 and located at the end of the slot 114 away from the rotating shaft 190. That is, the elastic element 195 is disposed in the slot 114 and abuts against the third side wall 1144. When the damping element 170 rotates to the position of contacting the elastic element 195, the temple 50 and the frame 40 are in an unfolded state. When the temple 50 continues to rotate until the second bracket 150 is in an outward folded state, the damping element 170 will press against the elastic element 195. At this time, the elastic element 195 applies an elastic force to the damping element 170, which will drive the damping element 170 to move towards the rotating shaft 190, thus clamping the temple 50 to the user's head. This can accommodate users with different head shapes and improve the adaptability of the frame. The elastic element 195 can be fixed to the third side wall 1144 in the slot 114 by means of adhesive or other means to prevent the elastic element 195 from shaking in the slot 114.

[0052] The elastic element 195 can be made of springs, elastic rubber, etc., and this embodiment is not limited to this. In one embodiment, the elastic element 195 is a silicone block. The advantage of using a silicone block is that it is easy to process the elastic element 195 into the form of a fitting slot 114, so that the elastic element 195 can be stably assembled in the slot 114 and is not easy to fall out or deform. At the same time, silicone has a strong elastic deformation capability, but the elastic force is relatively soft. When the user folds the temple 50 outward, the elastic force applied by the silicone block to the damping element 170 will not be too large, so it is not easy to cause the user to have a strong clamping feeling when wearing it, resulting in a better user experience. At the same time, silicone does not generate noise during the process of being compressed or deformed, and can also form a larger contact area with the damping element 170, providing a better cushioning effect.

[0053] It is understood that in other embodiments, the elastic element 195 may also be in other forms, such as a tension spring. This embodiment does not limit this.

[0054] The rotating shaft mechanism 100 provided in this application embodiment has a slot 114 provided on the first bracket 110, in which a damping element 170 is disposed and connected to the second bracket 150. When the second bracket 150 rotates relative to the first bracket 110, it will drive the damping element 170 to rotate. Since the damping element 170 rubs against the inner wall of the slot 114, a damping effect is formed on the damping element 170, so that the second bracket 150 connected to the damping element 170 can maintain a suspended posture and maintain a good suspension effect at any angle, which can adapt to the wearing of different users.

[0055] Specifically, when the user needs to unfold the folded frame, the temple 50 is driven to rotate relative to the frame 40. At this time, the temple 50 drives the second bracket 150 to rotate. The second bracket 150 drives the damping element 170 to slide relative to the slot 114 via the crank 180, thereby generating a damping force. When the user cancels the external force at any angle, the temple 50 will not continue to rotate due to the resistance of the damping element 170 and will remain in a suspended state. When the temple 50 is fully unfolded and worn on the user's head, the damping element 170 presses against the elastic element 195. The elastic element 195 provides elastic force to the damping element 170, and makes the temple 50 tend to move towards the folded state, thereby generating a clamping force to clamp the user's head. Similarly, when the user needs to fold the frame in the unfolded state, the temple 50 is driven to rotate relative to the frame 40. At this time, the temple 50 drives the second bracket 150 to rotate. The second bracket 150 drives the damping element 170 to slide relative to the slot 114 through the crank 180, thereby generating a damping force. When the user cancels the external force at any angle, the temple 50 will not continue to rotate due to the resistance of the damping element 170 and will remain in a suspended state.

[0056] In another embodiment, such as Figure 12 As shown, the glasses 10 can also be smart glasses. The smart glasses can include a frame 30, a display unit 70, an optical engine 60, and a flexible circuit board (not shown in the figure). The structure of the frame 30 can be referred to the above content, and will not be repeated here.

[0057] An optical engine 60 is disposed on the temple 50 and is used to modulate image light to project an image onto the display unit 70. The optical engine 60 can be any type of optical engine system, and no specific limitation is made here. There can be one, two, or multiple optical engines 60. In this embodiment, there is one optical engine 60, which is disposed on one temple 50 and mounted on the top of the temple 50. The display unit 70 is disposed on the frame 40. The display unit 70 can be a semi-transparent mirror 20. For example, the display unit 70 can transmit visible light except for red light and can reflect red light. The image light modulated by the optical engine 60 can use red light. When the image light is projected onto the display unit 70, it is reflected into the human eye, and the user can view the content projected by the optical engine 60. At the same time, non-red visible light in the ambient light can pass through the display unit 70 and enter the human eye, so the user can see objects in the environment while viewing the content projected by the optical engine 60. In another embodiment, a regular lens 20 may be disposed on the frame 40, and a display unit 70 may be disposed on the frame 40 and located in front of the lens 20, forming a display interface independent of the lens 20. No specific limitations are made here.

[0058] One end of the flexible printed circuit (FPC) is electrically connected to the optical engine 60, and the other end is electrically connected to the display unit 70, so as to form a signal transmission path between the optical engine 60 and the display unit 70. The flexible printed circuit can be routed along the temple 50 and pass through the pivot mechanism 100.

[0059] To facilitate the concealment of the flexible circuit board while simultaneously protecting it, please refer again to this embodiment. Figure 6 The arc plate 151 is provided with a notch 158, which corresponds to the second connecting part 155. When the second bracket 150 is in the unfolded state relative to the frame 40, a part of the second bracket 150 extends into the first content cavity 42. At this time, the part of the arc plate 151 with the notch 158 is located in the first content cavity 42 and communicates with the first content cavity 42.

[0060] Simultaneously, a gap 165 is formed between the body 161 and the arc-shaped plate 151. A notch 158 corresponds to and connects with the gap 165, forming a channel for the wire harness to pass through. The wire harness may include, for example, the aforementioned flexible circuit board; alternatively, it may be other cables, optical fibers, etc., which are not limited in this embodiment. The gap 165 can connect to the second internal cavity 51 of the temple 50. During wiring, such as... Figure 8 and Figure 9 As indicated by the dashed arrow S, the flexible circuit board passes through the second internal cavity 51, then through the gap 165 and the notch 158 into the first internal cavity 42. Since both the notch 158 and the gap 165 can be configured to a large size, the channel for the wire harness is relatively wide, allowing for the installation of more wire harnesses. Furthermore, this channel does not interfere with the first connecting part 112, the second connecting part 155, or the third connecting part 160, preventing damage to the wire harness during the folding or unfolding of the temple 50. Simultaneously, the third connecting part 160 also provides some restraint to the wire harness, preventing twisting or other phenomena within the channel.

[0061] It should be noted that the smart glasses 10 provided in this embodiment can be smart glasses 10 based on Virtual Reality (VR) technology. VR is a computer simulation system that can create and allow users to experience virtual worlds. It uses a computer to generate a simulated environment, immersing the user in that environment. Virtual reality technology utilizes real-life data, generates electronic signals through computer technology, and combines these signals with various output devices to transform them into phenomena that people can perceive. These phenomena can be real objects or substances invisible to the naked eye, represented through three-dimensional models.

[0062] It could also be smart glasses 10 based on Augmented Reality (AR) technology, a technology that cleverly integrates virtual information with the real world, overlaying virtual content onto real-world scenes. It uses computer technology to generate virtual information, such as visual images and sounds, and then applies this virtual information to the real world. Virtual reality technology not only displays information from the real world but can also simultaneously display virtual information, with the two types of information complementing and overlaying each other.

[0063] It can also be a smart glasses 10 based on Mixed Reality (MR) technology, which introduces real-world scene information into the virtual environment, and builds an interactive feedback loop between the virtual world, the real world and the user to enhance the realism of the user experience.

[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
