Description

Technical Field

[0001] This application relates to the field of eyeglasses technology, and more particularly to a rotating mechanism, a frame, and eyeglasses. Background Technology

[0002] Currently, eyeglasses have become a common accessory for some people, especially those with nearsightedness. With the development of technologies such as Virtual Reality (VR) and Augmented Reality (AR), smart glasses have emerged on top of traditional eyeglasses. Smart glasses use an optical engine to project image information onto the lenses of the glasses or a dedicated display screen, thus achieving intelligent functionality.

[0003] In related technologies, eyeglasses typically incorporate a rotating mechanism in the frame for easy storage, allowing the temples to fold inwards for storage and unfold for wearing. However, due to differences in head shape and circumference, the same pair of glasses may not fit properly on different users, especially those with larger head circumferences, who may experience discomfort from glasses that are too tight. This results in poor adaptability of eyeglasses to different users. Summary of the Invention

[0004] This application provides a rotating mechanism, a frame, and eyeglasses that can improve the adaptability of eyeglasses to different users.

[0005] The rotating mechanism provided in this application includes a first bracket, a rotating shaft, a guide rod, an elastic element, and a second bracket. The first bracket includes a retaining portion. The rotating shaft passes through the first bracket. The guide rod is sleeved on the rotating shaft. The elastic element is connected to the guide rod and can slide along the guide rod. The second bracket includes a first connecting section and a second connecting section connected to the first connecting section. A groove is formed on the second bracket, located between the first and second connecting sections. The guide rod is slidably disposed on the second connecting section. The second bracket has a first state during rotation relative to the first bracket. The groove has a first sidewall and a second sidewall connected to each other. When the second bracket is in the first state, the retaining portion can slide along the first sidewall and stop against the second sidewall. During the sliding of the retaining portion along the first sidewall, the compression of the elastic element remains unchanged.

[0006] The eyeglass frame provided in this application includes a frame, temples, and the rotating mechanism described in the above embodiments. The rotating mechanism connects the frame and the temples.

[0007] The eyeglasses provided in this application include the frame and lenses described in the above embodiments. The lenses are mounted on the frame.

[0008] In the rotating mechanism, frame, and glasses provided in this application embodiment, when the user wears the glasses, the clamping force remains unchanged when the second bracket is in the first state and the glasses continue to be folded outward, so that the clamping force of the temples is consistent for users with large head shapes and small head shapes, avoiding discomfort caused by the temples squeezing the head of users with large head circumferences, and improving the adaptability of the glasses to different users.

[0029] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between the components; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0031] Please see Figure 1 The eyeglass frame 200 provided in this embodiment is used for eyeglasses 1000, and the eyeglasses 1000 includes the eyeglass frame 200 and lenses 300, with the lenses 300 mounted on the frame 210. The rotating mechanism 100 provided in this embodiment is used for the eyeglass frame 200, which includes the frame 210 and temples 220, and the rotating mechanism 100 connects the frame 210 and the temples 220.

[0032] Please see Figures 2-4 The rotating mechanism 100 provided in this application includes a first bracket 10, a guide rod 20, an elastic element 30, a second bracket 40, and a rotating shaft 50. The first bracket 10 includes a holding portion 11. The rotating shaft 50 passes through the first bracket 10. The guide rod 20 is sleeved on the rotating shaft 50. The elastic element 30 is connected to the guide rod 20 and can slide along the guide rod. The second bracket 40 includes a first connecting section 41 and a second connecting section 42, the second connecting section 42 being connected to the first connecting section 41. A groove 401 is formed on the second bracket 40, located between the first connecting section 41 and the second connecting section 42, and the guide rod 20 is slidably disposed on the second connecting section 42. The second bracket 40 has a first state during rotation relative to the first bracket 10. The groove 401 has a first sidewall 4011 and a second sidewall 4012 connected to each other. When the second bracket 40 is in the first state, the holding part 11 can slide along the first side wall 4011 and stop at the second side wall 4012. During the process of the holding part 11 sliding along the first side wall 4011, the compression of the elastic member 30 remains unchanged.

[0033] Thus, when the second bracket 40 is in the first state and the outward-folding glasses 1000 are in the first state, the clamping force remains unchanged, so that the clamping force of the temple 220 is consistent for users with large head size and small head size, avoiding discomfort caused by the temple 220 squeezing the head of users with large head circumference, and improving the adaptability of the glasses to different users.

[0034] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0035] Specifically, in the eyeglasses 1000 of this embodiment, the lens 300 can be any type of lens, such as a plano lens, myopia lens, presbyopia lens, sunglasses lens, or colored lens, and is not limited here. The material of the lens 300 can be glass, resin, nylon, or crystal, and is not limited here. In some other embodiments, the lens 300 may not be provided, in which case the eyeglasses 1000 can be used as a decorative item for the user. The frame 210 of the frame 200 is used to mount the lens 300, and the temples 220 are connected to the frame 210 via a rotating mechanism 100 for the user to wear. It should be noted that the frame 210 and the temples 220 can be made of various materials such as metal, plastic, or ceramic, and are not limited here.

[0036] The frame includes two temples 220, each positioned on opposite sides of the frame 210 and connected to it. The two temples are arranged in a roughly symmetrical structure and are hinged to the sides of the frame 210 via two rotating mechanisms 100, facilitating their retraction and unfolding. Furthermore, the frame 210 has an extension that is bent relative to the frame 210. The rotating mechanism 100 is located at the end of the extension away from the frame 210. The temple 220 is connected to the rotating mechanism 100, and the end of the temple away from the rotating mechanism 100 is bent to form an ear hook, which can be suspended from the user's ear. The first bracket 10 of the rotating mechanism 100 is connected to the frame 210, and the second bracket 40 is connected to the temple 220.

[0037] In the rotating mechanism 100 provided in this embodiment, the guide rod 20 is rotatably connected to the first support 10 via a rotating shaft 50, and part of the guide rod 20 is connected to the second connecting section 42 of the second support 40. An elastic element 30 is sleeved on the guide rod 20, with one end of the elastic element 30 contacting the side of the second connecting section 42 opposite to the rotating shaft 50, and the other end of the elastic element 30 contacting the second support 40. When the guide rod 20 is subjected to an external force, the guide rod 20 can move relative to the first support 10 along its own axial direction, thereby causing the elastic element 30 to deform or recover its deformation. The guide rod 20 can be a square rod or a round rod, without limitation. The elastic element 30 can be a spring.

[0038] Specifically, a second through hole 421 may be provided on the second connecting section 42, and the guide rod 20 passes through the second through hole 421, such as... Figure 3 As shown. During the rotation of the second bracket 40 relative to the first bracket 10, the guide rod 20 can slide relative to the second bracket 40 along the axial direction of the second through hole 421. It can be understood that one end of the guide rod 20 is rotatably connected to the first bracket 10 through the rotating shaft 50, thereby ensuring that the guide rod 20 will not detach from the second bracket 40 due to excessive sliding distance when sliding relative to the second bracket 40.

[0039] Please see Figure 3 In some embodiments, a mounting groove 101 is formed on the first bracket 10, and one end of the guide rod 20 can be partially accommodated in the mounting groove 101 and rotatably connected to the first bracket 10. Specifically, a first mounting hole 102 is formed on the first bracket 10, and the first mounting hole 102 communicates with the mounting groove 101. A second mounting hole 221 is formed on the guide rod 20. The first mounting hole 102 and the second mounting hole 221 are coaxially arranged, and the rotating shaft 50 passes through the first mounting hole 102 and the second mounting hole 221 to realize the rotatable connection between the first bracket 10 and the guide rod 20.

[0040] In the rotating mechanism 100, the number of guide rods 20 can be one, two, or three, and the number of elastic elements 30 is the same as the number of guide rods 20. In one embodiment, there are two guide rods 20, which are spaced apart on the second connecting section 42 of the second bracket 40. The two guide rods 20 are rotatably connected to the first bracket 10 via two rotating shafts 50. The rotating shafts 50 can be screws or rivets, and there is no limitation on this.

[0041] Please see Figure 4 and Figure 5 It should be noted that when the second support 40 is in the first state, the glasses 1000 is in the outward expansion state. The outward expansion state refers to the state in which the temples 220 are expanded outward by an external force. Among them, if the glasses 1000 is in the outward expansion state, the angle between a temple 220 and the frame 210 can be less than or equal to 180 degrees or greater than 180 degrees, which is not limited here.

[0042] Specifically, the first sidewall 4011 is connected to the first connecting section 41, and the second sidewall 4012 is connected to the second connecting section 42. When the second bracket 40 is in the first state, when the holding part 11 moves on the first sidewall 4011 toward the first connecting section 41, the angle between the temple 220 and the frame 210 gradually decreases; when the holding part 11 moves on the first sidewall 4011 toward the second connecting section 42, the angle between the temple 220 and the frame 210 gradually increases.

[0043] It is understandable that when the second bracket 40 is in the first state, the holding part 11 is always in contact with the first sidewall 4011. When the second bracket 40 is in the first state, as the second bracket 40 gradually rotates away from the frame 210, the holding part 11 gradually moves towards the second sidewall 4012 on the first sidewall 4011. The angle between the frame 210 and the temple 220 gradually increases. Since the holding part 11 is in contact with the first sidewall 4011, the first sidewall 4011 can prevent the guide rod 20 from moving relative to the second bracket 40, so that the position of the second bracket 40 relative to the guide rod 20 remains unchanged, and the compression of the elastic element 30 remains unchanged, so that the clamping force is constant. Thus, the glasses 1000 using the embodiment of this application can avoid excessive clamping force causing discomfort to users with large head circumferences.

[0044] When the second bracket 40 is in the first state, the first side wall 4011 can fit against the outer wall of the holding part 11. The first side wall 4011 can provide a fulcrum position for the second bracket 40 to rotate relative to the first bracket 10. The first side wall 4011 can prevent the guide rod 20 from moving relative to the second bracket 40, thereby ensuring that the compression of the elastic element 30 remains constant, so that the clamping force of the temple 220 is constant, and the clamping force is prevented from continuously increasing and affecting the user experience of large-head-circle users wearing glasses 1000.

[0045] It is understandable that, since the second bracket 40 rotates relative to the first bracket 10 around the pivot 50, the first sidewall 4011 can be made into a curved surface, so that the holding part 11 can better fit against the first sidewall 4011 when sliding along the first sidewall 4011. In some embodiments, the second sidewall 4012 can also be an inclined surface, which is not limited here.

[0046] The maximum angle that the temples 220 and the frame 210 can open, or the maximum distance between the two temples 220, is related to the angle between the first sidewall 4011 and the first connecting segment 41. The angle between the first sidewall 4011 and the first connecting segment 41 can be controlled according to the head circumference of different user groups, and is not limited here.

[0047] Please see Figure 6 and Figure 7 In some embodiments, the second bracket 40 has a third state during rotation relative to the first bracket 10. When the second bracket is in the third state, the holding part 11 slides along the first connecting section 41 and stops at the connection point between the first connecting section 41 and the first sidewall 4011, and the elastic member 30 is compressed. As the holding part 11 slides on the first connecting section 41 and along the direction close to the first sidewall 4011, the compression of the elastic member 30 gradually increases, and the compression of the elastic member 30 when the second bracket 40 is in the first state is equal to the maximum value of the compression of the elastic member 30 when the second bracket 40 is in the third state.

[0048] Specifically, when the second bracket 40 is in the third state, as the second bracket 40 rotates in a direction away from the frame 210, the retaining part 11 gradually moves towards the groove 401 on the first connecting section 41, increasing the angle between the frame 210 and the temple 220, further compressing the elastic member 30, and gradually increasing the clamping force. Conversely, when the second bracket 40 is in the third state, as the second bracket 40 rotates in a direction closer to the frame 210, the retaining part 11 gradually moves away from the groove 401 on the first connecting section 41, decreasing the angle between the frame 210 and the temple 220, and gradually decreasing the clamping force.

[0049] Please see Figure 5 and Figure 7 The second support 40 can be rotated from a third state to a first state by rotating in a direction away from the frame 210, and the second support 40 can also be rotated from a first state to a third state by rotating in a direction closer to the frame 210. When the second support 40 is in the first and third states, the glasses 1000 are in an outward-expanding state. It should be noted that when the second support 40 is in the first state, the angle between the temple 220 and the frame 210 is greater than the angle between the temple 220 and the frame 210 when the second support 40 is in the third state.

[0050] When the second support 40 is in the third state, as the clamping force continues to increase to its maximum, the maximum width between the bent points of the two temples 220 is the first width. At this time, the clamping force is set to the preset clamping force, where the first width is less than the head width of a user with a small head size wearing the glasses 1000 provided in this embodiment. The second support 40 continues to bend outward to be in the first state. As the angle between the temples 220 and the frame 210 increases, the clamping force remains constant, that is, it is always equal to the preset clamping force, thus ensuring that the clamping force of the glasses 1000 is consistent for users with large head circumferences and users with small head circumferences when wearing the glasses 1000.

[0051] The preset clamping force ensures that the temples 220 will not suddenly expand outward while the user is wearing glasses 1000, and at the same time, the clamping force will not excessively compress the user's head, so as to ensure the user's experience when wearing glasses 1000.

[0052] Please see Figure 3 and Figure 5 In some embodiments, the first bracket 10 is provided with a relief groove 103, which forms a retaining part 11 with the outer wall of the first bracket 10. The relief groove 103 is used to avoid the groove 401 and the second connecting section 12.

[0053] Thus, when the second bracket 40 is in the first state, the clearance groove 103 can prevent the second bracket 40 from interfering with the second connecting section 42 and the second side wall 4012, thereby affecting the rotation of the second bracket 40. The outer side of the clamping part 11 abuts against the first side wall 4011, which ensures that the position of the second bracket 40 relative to the guide rod 20 remains unchanged, the compression of the elastic element 30 remains unchanged, and the clamping force remains constant.

[0054] Please see Figure 1 and Figure 8 In some embodiments, the first support 10 may include an abutment portion 12. The second support 40 has a second state during rotation relative to the first support 10. When the second support 40 is in the second state, the abutment portion 12 can slide along the second connecting segment 42, and the elastic element 30 is compressed. Thus, when the glasses 1000 folds inward, the pivot 50 and the abutment portion 12 rotate in coordination, the elastic element 30 is further compressed, and the inward folding is pried off using the connection point of the abutment portion 12 and the second connecting segment 42 as a lever fulcrum, forming an inward folding force. This ensures that the temples 220 of the glasses 1000 do not wobble when folded inward.

[0055] When the glasses 1000 is in the inward-folded state, the angle between the temples 220 and the frame 210 can be less than or equal to 90 degrees, or greater than 90 degrees but less than 180 degrees. No limitation is imposed here. For example, when the glasses 1000 is in the inward-folded state, the angle between the temples 220 and the frame 210 is 85 degrees. An angle less than 90 degrees between the temples 220 and the frame 210 allows the folded glasses 1000 to be relatively compact and easy to store.

[0056] The inward folding state refers to the state in which the temple 220 is folded inward by an external force. During the inward folding process, the maximum degree to which the frame 200 can be folded inward is when the two temples 220 are in contact and one of the temples 220 is in contact with the frame 210.

[0057] In one embodiment, when the second support 40 is in the second state, the temples 220 will not unfold under the action of gravity even if they face the ground while the user picks up the glasses 1000.

[0058] More specifically, the abutment portion 12 and the retaining portion 11 are spaced apart. The abutment portion 12 can be configured with a rounded chamfer, so that when the second bracket 40 is in the third state, the second connecting segment 42 can better maintain contact with the abutment portion 12, reducing the sudden change in the compression of the elastic member 30, making the temple 220 more smooth during inward folding and rotation. At the same time, the chamfered abutment portion 12 can also reduce wear on the second connecting segment 42 and improve the service life of the glasses 1000.

[0059] It should be noted that when the second support 40 gradually rotates from the second state to the first state or the third state, the glasses 1000 gradually changes from an inward folding state to an outward folding state; when the second support 40 gradually rotates from the first state or the third state to the second state, the glasses 1000 gradually changes from an outward folding state to an inward folding state.

[0060] Please see Figure 4 and Figure 5 In some embodiments, the second support 40 may include a cover 43 connected to the first connecting segment 41. The cover 43 extends from the first connecting segment 41 in a direction away from the first connecting segment 41 and is bent toward the pivot 50.

[0061] Thus, when the glasses 1000 are folded inward, the connection between the first support 10 and the second support 40 is exposed outside the frame 210 and the eyeglass frame 200, as... Figure 1 As shown. The cover 43 can protect the connection between the first bracket 10 and the second bracket 40, preventing foreign objects from entering the connection or damage from external forces, thereby extending the service life of the glasses 1000.

[0062] Please see Figure 1 , Figure 3 and Figure 4 In some embodiments, the first bracket 10 may further include a first mounting portion 13 and a second mounting portion 14, with the second mounting portion 14 connected to the first mounting portion 13. The first mounting portion 13 is used to connect to the frame 210, and the second mounting portion 14 is used to connect to the second bracket 40. A gap 104 is formed between the first mounting portion 13 and the second mounting portion 14 to avoid the second bracket 40 from colliding and interfering with the cover 43 during rotation of the second bracket 40. More specifically, the cover 43 is bent towards the second mounting portion 14, thereby protecting the connection between the first bracket 10 and the second bracket 40.

[0063] Please see Figure 1 and Figure 3 In some embodiments, the first mounting portion 13 of the second bracket 10 has at least one first mounting hole 131, and the mirror frame 210 is connected to a first connector (not shown) passing through the first mounting hole 131. In this way, the first connector can be used to achieve a stable connection between the first bracket 10 and the mirror frame 210, preventing the rotating mechanism 100 from falling off the mirror frame 210.

[0064] Specifically, the number of first mounting holes 131 can be one, two, three, or five, etc., and is not limited here. The number of first connectors is the same as the number of first mounting holes 131. In one embodiment, a first mounting hole 131 is provided on the first mounting part 13, and a first connector is selected and inserted into the first mounting hole 131, and the first connector is connected to the frame 210. The first connector can be a screw. The first mounting part 13 and the second mounting part 14 can be connected by welding or bonding. Preferably, the first mounting part 13 and the second mounting part 14 are integrally formed. There are no limitations here.

[0065] Please see Figure 3 In some embodiments, a protrusion 141 is formed on the second mounting portion 14 of the first bracket 10 at one end opposite to the second bracket 40. A recess (not shown) is formed on the frame 210 that matches the protrusion 141. The protrusion 141 can be held in the recess, thereby further strengthening the connection between the first bracket 10 and the frame 210 and preventing the rotating mechanism 100 from falling off the frame 210.

[0066] Please see Figure 3 and Figure 4 In some embodiments, the second bracket 40 may include a boss 44, on which a first through hole 441 is formed, the guide rod 20 passes through the first through hole 441, and the end of the elastic member 30 facing away from the first bracket 10 abuts against the boss 44.

[0067] Thus, the boss 44 can be used to install the guide rod 20, and the elastic element 30 can deform between the boss 44 and the second connecting section 42 during the rotation of the second bracket 40. When the guide rod 20 moves axially and causes the elastic element 30 to deform, the boss 44 can prevent the elastic element 30 from falling off the second bracket 40.

[0068] Specifically, the boss 44 is spaced apart from the second connecting section 42 and located on the side of the second connecting section 42 opposite to the rotating shaft 50. The number of bosses 44 can be one, two, or three, etc., and the number of bosses 44 corresponds to the number of guide rods 20, which is not limited here.

[0069] Please see Figure 3 and Figure 4 In some embodiments, the guide rod 20 may include a rod body 21 and a limiting block 22. The limiting block 22 is connected to the rod body 21, which passes through the first through hole 441, and the limiting block 22 is sleeved on the rotating shaft 50. In this way, the limiting block 22 can prevent the rod body 21 from slipping out of the second connecting section 42 during rotation, thereby affecting the normal operation of the rotating mechanism 100.

[0070] The rod 21 and the limiting block 22 can be connected by welding or bonding, or the rod 21 and the limiting block 22 can be integrally formed, which is not limited here.

[0071] In some embodiments, a first mounting hole 102 is formed on the first bracket 10, and a second mounting hole 221 is formed on the limiting block 22. The first mounting hole 102 and the second mounting hole 221 are coaxially arranged, and the rotating shaft 50 passes through the first mounting hole 102 and the second mounting hole 221 to realize the rotational connection between the first bracket 10 and the guide rod 20.

[0072] In some embodiments, at least one set of ear plates (not shown) is provided on the first bracket 10 near the second bracket 40. Each set of ear plates includes a first ear plate and a second ear plate that are arranged opposite to each other and spaced apart. The limiting block 22 is connected to the first ear plate and the second ear plate. The number of ear plates can also be two or three sets, etc., and the number of ear plates corresponds to the number of guide rods 20. There is no limitation on this.

[0073] Specifically, a first mounting hole 102 may be formed on the first ear plate and the second ear plate, and a second mounting hole 221 may be formed on the limiting block 22. The second mounting hole 221 is coaxially arranged with the two first mounting holes 102. The limiting block 22 is rotatably connected with the first ear plate and the second ear plate by a rotating shaft 50 passing through the first mounting hole 102 and the second mounting hole 221.

[0074] Please see Figure 3 and Figure 4 In some embodiments, the rotating mechanism 100 may further include a latch 60, and a slot 201 is provided on the side of the rod 21 opposite to the limiting block 22. The latch 60 engages with the slot 201 to limit the elastic member 30. Thus, when the temple 220 expands outward or folds inward, when the guide rod 20 moves axially and causes the elastic member 30 to deform, the latch 60 abuts against the end of the elastic member 30 opposite to the limiting block 22, and the elastic member 30 is compressed between the latch 60 and the second connecting section 42, providing the required outward and inward folding force. The latch 60 may be an E-shaped latch.

[0075] In some embodiments, the rotating mechanism 100 may further include a shim 70, which is disposed on the side of the buckle 60 near the limiting block 22, and abuts against the end of the elastic member 30 away from the limiting block 22. Thus, the shim 70 can reduce wear between the elastic member 30 and the buckle 60. The shim 70 can be a wear-resistant shim, and its material can be elastic or flexible materials such as rubber. When the temple 220 is folded outwards or inwards, when the guide rod 20 moves axially, causing the elastic member 30 to deform, the elastic member 30 is compressed between the buckle 60, the shim 70, and the second connecting section 42, providing the required outward and inward folding force.

[0076] Please seeFigure 3 In some embodiments, the second bracket 40 may include a plate 45 connected to the temple 220. The plate 45 has at least one second mounting hole 451, and the temple 220 is connected to a second connector (not shown) passing through the second mounting hole 451. Thus, the second connector passing through the second mounting hole 451 enables a stable connection between the second bracket 40 and the temple 220, preventing the rotating mechanism 100 from detaching from the temple 220.

[0077] Specifically, the number of second mounting holes 451 can be one, two, three, or five, etc., and there is no limitation here. The number of second connectors is the same as the number of second mounting holes 451. In one embodiment, two spaced second mounting holes 451 are provided on the plate 45, so that two second connectors can be respectively inserted into the second mounting holes 451, and both second connectors are connected to the temple 220.

[0078] In some embodiments, the temple 220 may be formed with a receiving cavity, so that part of the second support 40 can be accommodated in the receiving cavity, which not only improves the aesthetics of the frame 200, but also protects part of the second support 40.

[0079] Please see Figure 9 In some embodiments, the eyeglasses 1000 may further include an optical engine 400 and a flexible circuit board 500. The optical engine 400 is disposed on the temple 220. One end of the flexible circuit board 500 is electrically connected to the optical engine 400, and the other end is electrically connected to the lens 300. Thus, under the action of the flexible circuit board 500, the optical engine 400 can modulate image light to project an image onto the lens 300.

[0080] Understandably, when the glasses 1000 are smart glasses, they can also include an optical engine 400 and a flexible circuit board 500. The smart glasses can be head-mounted display devices such as AR glasses, VR glasses, or MR glasses. The optical engine 400 is used to modulate image light to project an image onto the lens 300. The optical engine 400 can be detachably connected to the temple 220 via any one or a combination of magnetic, threaded, or snap-fit ​​methods.

[0081] There can be one, two, or multiple optical engines 400. Lenses 300 are set in the frame 210. Lenses 300 can be semi-transparent and semi-reflective lenses. For example, lenses 300 can transmit visible light except for red light and can reflect red light. The image light modulated by the optical engine 400 can use red light. When the image light is projected onto the lens 300, it is reflected into the human eye, and the user can view the content projected by the optical engine 400. At the same time, non-red visible light in the ambient light can pass through the lens 300 and enter the human eye, so the user can see objects in the environment while viewing the content projected by the optical engine 400.

[0082] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0083] One end of the flexible circuit board 500 is electrically connected to the optical engine 400, and the other end can run along the temple 220 and extend to the frame 210, where it is electrically connected to the lens 300 to form a signal transmission path between the optical engine 400 and the lens 300. The flexible circuit board 500 can run along the temple 220 and pass through the rotating mechanism 100. It is understood that in some embodiments, the first support 10 and / or the second support 40 have holes to allow the flexible circuit board 500 to pass through.
