[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] In order to facilitate storage, glasses in the related art usually have a rotating shaft mechanism on the frame, so that the temples of the glasses can be folded and stored, and can also be rotated to the angle required by the user for wearing. Due to the differences in head shape, head circumference, pupil distance, etc. of different users, the rotation angle when wearing will be different. It is necessary for the rotating shaft mechanism to be able to maintain a hovering state at any rotation angle to meet the wearing needs of different users. Based on this, the inventors of the present application have proposed the rotating shaft mechanism, frame, glasses and smart glasses of each embodiment of the present application, in order to improve the above-mentioned defects and provide the applicability of the frame of the glasses. The following is a detailed description of each embodiment of the present application in conjunction with the accompanying drawings.

[0025] See also Figure 1 The present embodiment provides a pair of glasses 10, wherein the glasses 10 include a frame 30 and a lens 20, and the lens 20 can be mounted on the frame 30. The lens 20 can be a plain lens, a myopia lens, a presbyopic lens, a filter lens, a color lens, and other types of lenses, which are not limited here. The lens 20 can be made of glass, resin, and other materials, which are not limited here. In some other embodiments, the lens 20 may not be provided, and the glasses 10 can only be used as a decorative tool for the user.

[0026] The frame 30 includes temples 50, a frame 40, and a rotating shaft mechanism 100, wherein the frame 40 is used to mount the lens 20, and the temples 50 are connected to the frame 40 and are used for the user to wear. It should be noted that the frame 40 and the temples 50 can be made of various materials such as metal, plastic, ceramic, etc., which are not limited here. The frame 40 can include two independent frame structures for mounting two separate lenses 20, which correspond to the left eye and the right eye of the user respectively.

[0027] There may be two temples 50, which are respectively disposed on opposite sides of the frame 40 and connected to the frame 40. The two temples 50 are arranged in a substantially symmetrical structure, and the temples 50 are hinged to the frame 40 through a rotating shaft mechanism 100, so as to store the temples 50. Specifically, the frame 40 is provided with an extension portion 41, which is bent relative to the frame 40, and the rotating shaft mechanism 100 is disposed at one end of the extension portion 41 away from the frame 40, and the temple 50 is connected to the rotating shaft mechanism 100, and one end of the temple 50 away from the rotating shaft mechanism 100 is bent to form an ear hook 55, and the ear hook 55 is suitable for hanging on the ear of the user.

[0028] Specifically, in this embodiment, please refer to Figure 2 and Figure 3 The extension portion 41 forms a first content cavity 42, and a second content cavity 51 is formed in the temple 50. The second content cavity 51 is located at one end of the temple 50 close to the extension portion 41. The first content cavity 42 and the second content 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.

[0029] See also Figure 4 The shaft mechanism 100 includes a first bracket 110, a second bracket 150, a shaft 190, a first damping portion 171, and a second damping portion 176. In one embodiment, the first bracket 110 can be used to connect the frame 40, the second bracket 150 can be used to connect the temple 50, the first bracket 110 can also be used to connect the temple 50, the second bracket 150 can be used to connect the frame 40, the first bracket 110 and the second bracket 150 are rotatably connected through the shaft 190, so that the second bracket 150 can rotate relative to the first bracket 110. Specifically, the first bracket 110 can at least partially extend into the first inner cavity 42, and be fixed to the frame 40 by means of adhesive, screw connection, etc., the second bracket 150 can at least partially extend into the second inner cavity 51, and be fixed to the temple 50 by means of adhesive, screw connection, etc. The first damping portion 171 is disposed in the first bracket 110, and the second damping portion 176 is disposed in the second bracket 150. The first damping portion 171 and the second damping portion 176 are used to provide damping during the rotation of the second bracket 150 relative to the first bracket 110, so that the second bracket 150 can remain suspended during the rotation relative to the first bracket 110.

[0030] Please continue reading Figure 4 In this embodiment, the first damping part 171 is disposed on the first bracket 110, and the second damping part 176 is disposed on the second bracket 150. It is understandable that in some other embodiments, the first damping part 171 may also be disposed on the second bracket 150, and correspondingly, the second damping part 176 may also be disposed on the first bracket 110.

[0031] For details about this embodiment, please refer to Figure 4 and Figure 5 The first bracket 110 includes a guide plate 111 and two first connecting parts 112 disposed at both ends of the guide plate 111. Each first connecting part 112 is provided with a first axial hole 113. The first axial hole 113 passes through the first connecting part 112, and the first axial holes 113 of the two first connecting parts 112 are coaxially arranged. The first connecting part 112 is used to install the rotating shaft 190. The two first connecting parts 112 are symmetrically distributed relative to the guide plate 111. The guide plate 111 is used to cooperate with the second bracket 150 to form a guide, so that the second bracket 150 maintains a predetermined track during the rotation process relative to the first bracket 110. In this embodiment, the guide plate 111 is configured to be arc-shaped, and the two first connecting parts 112 are located on the inner side of the guide plate 111.

[0032] In one embodiment, the two first connection parts 112 can be configured to be suitable for extending into the first inner cavity 42, so that when installed in the frame 40, the two first connection parts 112 can be embedded in the first inner cavity 42, so that the first bracket 110 can be shielded and the appearance of the frame can be improved. The two first connection parts 112 are arranged with a gap 165 between them, so that an installation space is formed between the two first connection parts 112.

[0033] Please refer again Figure 5 Each first connection portion 112 is provided with a card slot 114. In this embodiment, the card slot 114 has an opening, and the opening direction of the opening is toward the extension direction of the guide plate 111, that is, the opening direction of the card slot 114 is toward the second bracket 150. The first connection portion 112 is also provided with a mounting slot 116, and the mounting slot 116 is used to set the first damping portion 171. The mounting slot 116 is connected to the card slot 114 and is located at an end of the card slot 114 away from the guide plate 111. In this embodiment, the first shaft hole 113 is connected to the mounting slot 116. A step is formed between the mounting slot 116 and the card slot 114, so that the first damping portion 171 set in the mounting slot 116 cannot enter the card slot 114.

[0034] It is understandable that the structures of the two first connecting parts 112 may be the same. Providing two first connecting parts 112 can enhance the stability of the first bracket 110 and the second bracket 150 during the connection process. In some other embodiments, only one first connecting part 112 may be provided, which is not limited in this embodiment.

[0035] Please also read Figure 4 and Figure 6The 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 portion 155, and the second connecting portion 155 can be embedded between the two first connecting portions 112. The second connecting portion 155 is provided with a second axial hole 156, and the second axial hole 156 can be coaxially arranged with the first axial holes 113 of the first connecting portions 112 on both sides of the second connecting portion 155. The rotating shaft 190 is penetrated through the first axial hole 113 and the second axial hole 156, so that the second bracket 150 can rotate relative to the first bracket 110.

[0036] For more details, please refer to Figure 6 In this embodiment, the second bracket 150 includes an arc plate 151, a first cover plate 152, a second cover plate 153, a second connection portion 155 and a third connection portion 160. The first cover plate 152 and the second cover plate 153 are arranged opposite to each other and connected to the edge of the arc plate 151. In one embodiment, the second connection portion 155 is located between the first cover plate 152 and the second cover plate 153. When assembled, the first bracket 110 is arranged between the first cover plate 152 and the second cover plate 153, and the two first connection portions 112 are adjacent to the first cover plate 152 and the second cover plate 153 respectively. The first cover plate 152 and the second cover plate 153 can block the first connection portion 112, thereby improving the appearance of the hinge mechanism 100.

[0037] The spacing between the second connection part 155 and the first cover plate 152 and the spacing between the second connection part 155 and the second cover plate 153 are roughly equivalent to the thickness of the first connection part 112, so that the first connection part 112 can be conveniently embedded between the second connection part 155 and the first cover plate 152 / the second cover plate 153, and the compactness of the structure can be maintained. At the same time, the spacing between the two first connection parts 112 is roughly equal to the spacing between the second connection parts 155, so that the second connection part 155 can be conveniently embedded between the two first connection parts 112, and the compactness of the structure can be maintained.

[0038] In a more specific embodiment, the first cover plate 152 and the second cover plate 153 can both be roughly arc-shaped structures and be consistent with the curvature of the arc plate 151. The first cover plate 152 and the second cover plate 153 can be completely opposite to each other and symmetrically distributed on the opposite side edges of the arc plate 151. The guide plate 111 can fit with the arc plate 151, and in the process of the second bracket 150 rotating relative to the first bracket 110, it always slides and fits with the inner side of the arc plate 151, thereby playing a guiding role. The curvature of the guide plate 111 can be configured to be consistent with the curvature of the arc plate 151. Further, 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 steps of the two first connecting portions 112. By providing the step, a guiding effect can be formed on the second bracket 150, thereby improving the stability of the second bracket 150 when rotating relative to the first bracket 110.

[0039] The third connection part 160 is connected to the arc plate 151 and is used to set the second damping part. In this embodiment, the second connection part 155 is connected to the third connection part 160, and is fixed relative to the arc plate 151.

[0040] In this embodiment, the first damping portion 171 can be slidably disposed in the slot 114, and the first damping portion 171 is connected to the third connecting portion 160. When the first damping portion 171 slides in the slot 114, sliding friction will occur with the walls that surround the slot 114 (i.e., at least one of the aforementioned bottom wall 1141, the first side wall 1142, and the second side wall 1143), thereby generating a damping force, so that the second bracket 150 cannot rotate independently relative to the first bracket 110. Only when driven by an external force and overcoming the friction resistance between the first damping portion 171 and the walls that surround the slot 114, can the first damping portion 171 slide relative to the slot 114, and then the second bracket 150 can rotate relative to the first bracket 110, so that the second bracket 150 can hover at any angle relative to the first bracket 110 during the rotation process.

[0041] In one embodiment, please refer to Figure 7 and Figure 8The first damping part 171 includes a block 172 and a damping block 173. The block 172 is shaped to cooperate with the mounting groove 116. The block 172 is embedded in the mounting groove 116. The damping block 173 is connected to the block 172 and is retractable relative to the block 172, so that the damping block 173 can cooperate with the second damping part 176 during the retraction process. Specifically in this embodiment, the block 172 is provided with an assembly hole 1721, which can be a stepped hole. The damping block 173 is configured as a substantially rod-shaped structure. The damping block 173 is slidably assembled in the assembly hole 1721 and can extend out of the assembly hole 1721. When the damping block 173 extends out of the assembly hole 1721, it cooperates with the second damping part 176. When the damping block 173 is separated from the second damping part 176, the damping block 173 and the second damping part 176 do not interfere with each other. In particular, the depth of the assembly hole 1721 may be greater than the length of the damping block 173 , so that the damping block 173 may be completely retracted into the assembly hole 1721 .

[0042] The first damping part 171 further includes an elastic member 174, which is assembled in the assembly hole 1721 and is used to provide a restoring force to the damping block 173 to drive the damping block 173 to extend out of the assembly hole 1721. In this embodiment, an end cap 175 is provided at one end of the damping block 173 close to the second damping part 176, and the outer diameter of the end cap 175 is larger than the outer diameter of the damping block 173. The end cap 175 can extend out of the assembly hole 1721 and cooperate with the second damping part 176 during the extension and contraction process of the damping block 173. The elastic member 174 is a spring, which is sleeved outside the damping block 173, and one end of the elastic member 174 can abut against the end cap 175, and the other end can abut against the step in the assembly hole 1721. When the end cap 175 is driven by an external force to move toward the assembly hole 1721, the end cap 175 can compress the elastic member 174, causing the elastic member 174 to deform elastically. When the external force disappears, the elastic member 174 restores the elastic deformation to drive the damping block 173 to move out of the assembly hole 1721. In order to facilitate the damping block 173 to be quickly retracted into the assembly hole 1721 when subjected to external pressure, the surface of the end cap 175 can be configured as a spherical surface. The advantage of this arrangement is that when the spherical end cap 175 is subjected to lateral or tangential force, the torque can be better converted into the force in the sliding direction of the damping block 173, making the sliding process of the damping block 173 smoother and avoiding the occurrence of jamming.

[0043] In some other embodiments, the damping block 173 may also be configured to be retractable in other ways, such as by configuring a miniature cylinder to drive the damping block 173 to move and retract.

[0044] In this embodiment, please combine Figure 4 , Figure 7 as well as Figure 8, there are two first damping parts 171, and they are assembled correspondingly with the two first connecting parts 112. The rotating shaft 190 includes a first rotating shaft 191 and a second rotating shaft 192 which are arranged coaxially. The first rotating shaft 191 is connected to the block 172 of one first damping part 171, and is embedded in the first shaft hole 113 of one first connecting part 112 and the second shaft hole 156 of the second connecting part 155. The second rotating shaft 192 is connected to the block 172 of another first damping part 171, and is embedded in the first shaft hole 113 of another first connecting part 112 and the second shaft hole 156 of the second connecting part 155. It can be understood that in some other embodiments, the rotating shaft 190 can also be set as one, and is assembled in the first shaft hole 113 of the two first connecting parts 112 and the second shaft hole 156 of the second connecting part 155 at the same time.

[0045] In this embodiment, the second damping portion 176 is connected to the third connecting portion 160 and is arranged toward the first damping portion 171. The second damping portion 176 is provided with a plurality of fixed positions 177. Each fixed position 177 can cooperate with the damping block 173 to realize the positioning of the damping block 173. When the damping block 173 cooperates with a fixed position 177, the rotational freedom between the second bracket 150 and the first bracket 110 is restricted, and relative rotation cannot occur between the second bracket 150 and the first bracket 110, thereby realizing damped suspension between the first bracket 110 and the second bracket 150.

[0046] In this embodiment, the second damping portion 176 has an arc surface 179 facing the first bracket 110, and a plurality of fixing positions 177 are arranged on the arc surface 179, and the curvature of the arc surface 179 matches the rotation path of the second bracket 150 when it rotates relative to the first bracket 110. During the rotation of the second bracket 150 relative to the first bracket 110, the plurality of fixing positions 177 are located on the telescopic path of the damping block 173, so that the damping block 173 can cooperate with any of the fixing positions 177 during the telescopic process. In one embodiment, the fixing position 177 is a fixing groove 178 arranged on the arc surface 179, and the damping block 173 can at least partially extend into the fixing groove 178 to limit the rotational freedom of the second bracket 150. In some other embodiments, the fixing position 177 can also be arranged in other forms, for example, the fixing position 177 is arranged in the form of a protrusion, and the end cap 175 of the damping block 173 is provided with a clamping hole structure corresponding to the protrusion, which can also achieve the cooperation between the damping block 173 and the fixing position 177.

[0047] The inner wall of the fixing groove 178 can be configured to match the end cap 175 of the damping block 173, for example, the inner wall of the fixing groove 178 can be configured to be a spherical surface. In this configuration, when the end cap 175 of the damping block 173 is inserted into the fixing groove 178, the outer surface of the end cap 175 and the inner wall of the fixing groove 178 can be better matched. At the same time, when the second bracket 150 continues to rotate, the rotation torque is transmitted to the end cap 175 through the second damping part 176, and the torque transmission process is smoother. The end cap 175 can be quickly squeezed out of the fixing groove 178 and pressed back into the assembly hole 1721, so that when the user rotates the first bracket 110 and the second bracket 150, the movement of the rotating shaft 190 mechanism is smoother and will not get stuck.

[0048] The number of the fixing positions 177 determines the angle range in which the second bracket 150 can hover during the rotation relative to the first bracket 110. For example, when there are three fixing positions 177, the second bracket 150 can hover at three angle positions during the rotation relative to the first bracket 110. Therefore, the more the number of the fixing positions 177, the more angle positions that can be hovered. However, if there are too many fixing positions 177, for the user, there may be a problem of excessive damping and inconvenience during the folding of the temples 50. In one embodiment, the number of the fixing positions 177 may be 3-4. The arc between two adjacent fixing positions 177 is π / 4-π / 8, and in particular, in one embodiment, the arc between two adjacent fixing positions 177 may be π / 6.

[0049] In this embodiment, there are two second damping parts 176 , and the two second damping parts 176 are both disposed on the third connecting part 160 of the second bracket 150 , and are respectively disposed corresponding to the two first damping parts 170 .

[0050] By providing the first damping portion 171 and the second damping portion 176, the user can realize the hovering of the first bracket 110 and the second bracket 150 at different positions when folding and storing the temple 50, so that the user can choose different hovering angles for wearing and adapt to users with different head shapes.

[0051] When the temple 50 is in the unfolded state relative to the frame, for different users, due to different head shapes, for people with large heads, the temple 50 may be stretched out and then "folded outward" relative to the frame. In this process, if a large outward folding angle is reserved for the second bracket 150, the temple 50 will not be able to clamp the head well when people with small heads use it, causing the frame to fall off easily. Therefore, in this embodiment, please continue to refer to Fig.10 and Fig.11The rotating shaft mechanism 100 may further include an elastic member 195, which is disposed in the card slot 114 and located at an end of the card slot 114 away from the rotating shaft 190. When the temple 50 rotates to the second bracket 150 in the outward folded state, as shown in FIG. Fig. 9 As shown, the second damping part 176 can extend into the card slot 116 and abut against the elastic member 195. At this time, the elastic member 195 applies an elastic force to the second damping part 176, which drives the second bracket 150 to move inward relative to the first bracket 110, so that the temple 50 clamps the user's head, so that it can adapt to users with different head shapes and improve the adaptability of the frame. The elastic member 195 can be fixed in the card slot 114 by means of adhesive or the like to prevent the elastic member 195 from shaking in the card slot 114. Fig.10 As shown, when the temple 50 rotates to be folded with the frame 40 , the second bracket 150 rotates to be folded with the first bracket 110 , at which time the elastic member 195 is disengaged from the second damping portion 176 , and the second damping portion 176 is located outside the slot 114 .

[0052] The elastic member 195 may be a spring, elastic rubber, etc., which is not limited in this embodiment. In one embodiment, the elastic member 195 is a silicone block. The advantage of using a silicone block is that it is easy to process the elastic member 195 into a form that fits the card slot 114, so that the elastic member 195 can be stably assembled in the card slot 114 and is not easy to fall out or deform. At the same time, the elastic deformation ability of silicone is relatively strong, but the elastic force is relatively gentle. When the user folds the temple 50 outward, the elastic force applied by the silicone block to the second damping part 176 will not be too large, so it is not easy to cause the user to have a strong clamping feeling when wearing it, and the user experience is better. At the same time, silicone is not easy to generate noise during pressure or deformation, and can also form a larger contact area with the second damping part 176, providing a better buffering effect.

[0053] It is understandable that in some other implementations, the elastic member 195 may also be in other forms. For example, the elastic member 195 may be configured as a tension spring, which is not limited in this embodiment.

[0054] The hinge mechanism 100 provided in the embodiment of the present application is configured such that a first damping portion 171 is disposed on the first bracket 110 and a second damping portion 176 is disposed on the second bracket 150. When the second bracket 150 rotates relative to the first bracket 110, the damping block 173 of the first damping portion 171 can be embedded in a fixed position 177 of the second damping portion 176, so that the first bracket 110 and the second bracket 150 can maintain a hovering posture to adapt to wearing by 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, and the temple 50 drives the second bracket 150 to rotate. When the temple 50 rotates to the point where the damping block 173 corresponds to a fixed position 177, the damping block 173 extends out of the assembly hole 1721 under the action of the elastic member 174 and engages in a fixed position 177, so that the first bracket 110 and the second bracket 150 remain in a suspended state. When the rotational torque continues to be applied to the temple 50, the second damping portion 176 presses the damping block 173 back into the assembly hole 1721, and the first bracket 110 and the second bracket 150 can rotate relative to each other. When the temple 50 is fully unfolded and worn on the user's head, the second damping portion 176 presses against the elastic member 195, and the elastic member 195 provides elastic force to the second damping portion 176, and makes the temple 50 have a tendency to move toward the folded state, thereby generating a clamping force to clamp the user's head. Similarly, when the user needs to fold the unfolded 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. When the temple 50 rotates until the damping block 173 corresponds to a fixed position 177, the damping block 173 extends out of the assembly hole 1721 under the action of the elastic member 174 and engages in a fixed position 177, so that the first bracket 110 and the second bracket 150 remain in a suspended state. When the rotational torque continues to be applied to the temple 50, the second damping part 176 presses the damping block 173 back into the assembly hole 1721. At this time, the first bracket 110 and the second bracket 150 can rotate relative to each other.

[0056] In another embodiment, Fig.11 As shown, the glasses 10 can also be smart glasses, which may include a frame 30, a display unit 70, an optical engine 60, and a flexible circuit board (not shown). The structure of the frame 30 can be found in the aforementioned content and will not be repeated here.

[0057] The optical machine 60 is arranged on the temple 50 and is used to modulate the image light to project the image on the display unit 70. The optical machine 60 can be various types of optical machine 60 systems, which are not specifically limited here. The optical machine 60 can be one, two, or multiple. In this embodiment, there is one optical machine 60, which is arranged on one temple 50 and loaded on the top of the temple 50. The display unit 70 is arranged on the frame 40, wherein the display unit 70 can be a semi-transparent and semi-reflective lens 20. For example, the display unit 70 can transmit visible light except red light and can reflect red light. The image light modulated by the optical machine 60 can use red light. When the image light is projected onto the display unit 70, it is reflected into the human eye. The user can see the content projected by the optical machine 60. At the same time, the visible light other than red light in the ambient light can enter the human eye through the display unit 70. The user can see the objects in the environment while watching the content projected by the optical machine 60. In another embodiment, a common lens 20 may be disposed on the frame 40, and the display unit 70 is disposed on the frame 40 and located in front of the lens 20, forming a display interface independent of the lens 20. No specific limitation is made herein.

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

[0059] In order to hide the flexible circuit board and protect the flexible circuit board, in this embodiment, please refer to Figure 6 The arc plate 151 is provided with a notch 158, and the notch 158 corresponds to the second connecting portion 155. When the second bracket 150 is in an unfolded state relative to the mirror frame 40, a portion of the second bracket 150 extends into the first content cavity 42. At this time, the portion of the arc plate 151 where the notch 158 is provided is located in the first content cavity 42 and is connected to the first content cavity 42.

[0060] At the same time, a gap 165 is formed between the third connecting portion 160 and the curved plate 151, and the gap 158 corresponds to the gap 165 and is connected to form a channel for the wire harness to pass through. The wire harness can include, for example, the aforementioned flexible circuit board. In addition, the wire harness can also be other cables, optical cables, etc., which are not limited in this embodiment. The gap 165 can be connected to the second content cavity 51 of the temple 50. When routing, the flexible circuit board passes through the second content cavity 51 and passes through the gap 165 and the gap 158 to enter the first content cavity 42. Since the gap 158 and the gap 165 can be configured to be larger in size, the channel for the wire harness to pass through is relatively spacious, and more wire harnesses can be set. And the channel will not interfere with the first connecting portion 112, the second connecting portion 155 and the third connecting portion 160, and will not damage the wire harness during the folding or unfolding of the temple 50. At the same time, the third connecting portion 160 can also have a certain limiting effect on the wire harness to avoid the phenomenon of the wire harness twisting in 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 technology (VR), which is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment to immerse the user in the environment. Virtual reality technology uses real-life data, electronic signals generated by computer technology, and combines them with various output devices to transform them into phenomena that people can feel. These phenomena can be real objects in reality or substances that are invisible to our naked eyes, which are expressed through three-dimensional models.

[0062] It can also be a smart glasses 10 based on augmented reality (AR) technology, which is a technology that cleverly integrates virtual information with the real world and superimposes virtual display content on the real scene. It generates virtual information such as visual images, sounds, etc. through computer technology; then applies the virtual information to the real world. Virtual reality technology not only displays real-world information, but also can display virtual information at the same time, and the two types of information complement and overlap each other.

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

[0064] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
