Description

Technical Field

[0002] AR glasses usually include a frame, an optical module and a control module, wherein the frame includes a frame and temples, and the optical module includes an optical engine and a waveguide, wherein the optical engine is mounted on the temples and the waveguide is mounted on the frame. When the AR glasses are in use, the optical engine inputs image data to the waveguide as an image source, and the image enters the human eye after total reflection by the waveguide to form an image. When users with different head widths wear AR glasses, the frame and temples will be deformed, causing the angle of the incident light from the optical engine to rotate, causing the angle of the emitted light from the waveguide to rotate and not be parallel to the user's line of sight, so that the user's eyes cannot normally fuse the image reflected by the waveguide into a complete image, affecting the use effect.

[0074] AR glasses are a new type of glasses for augmented reality applications. Most AR glasses have various functions such as display, photography, video calls, text message processing, email, games and entertainment, etc. AR glasses can display virtual scenes while displaying real scenes. Users can even interact with virtual scenes. It is a new form of future smart hardware products.

[0075] AR glasses mainly include three modules, namely control module, optical module and bracket. Among them, the CPU processing center is mainly responsible for the input, virtual and real combination and output of AR glasses, and the optical module is mainly responsible for the imaging of AR glasses. The optical module usually includes an optical machine and a waveguide. The optical machine is used as an image source to input image data to the coupling structure of the waveguide, and after total reflection from the base of the waveguide, it is coupled into the human eye through the coupling structure of the waveguide to form an image.

[0076] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of the AR glasses provided in this application in a specific embodiment. The AR glasses 1 include a frame 11 and temples 12 connected to each other, an optical machine is installed on the temples 12, the frame 11 is provided with lenses, and waveguides are installed on the lenses. When the AR glasses 1 are used, the two optical machines on the temples 12 serve as image sources, which can generate images and input image data to the two waveguides located on the frame 11, and then enter the human eye after reflection by the waveguide to form an image, wherein the emission angles of the two waveguides need to be parallel to the user's binocular line of sight, so that the user's eyes can fuse the images reflected by the two waveguides into a complete image.

[0077] like Figure 1 As shown, the frame 11 includes a first frame 111 and a second frame 112 symmetrically arranged along a first direction X, and the temples 12 include a first temple 121 and a second temple 122 symmetrically arranged along the first direction X, the first frame 111 is connected to the first temple 121, and the second frame 112 is connected to the second temple 122. A first optical machine is mounted on the first temple 121, and a second optical machine is mounted on the second temple 122. A first waveguide corresponding to the first optical machine is mounted on the first frame 111, and a second waveguide corresponding to the second optical machine is mounted on the second frame 112. When a user uses the AR glasses 1, the emission angle of the first waveguide is parallel to the user's left eye line of sight, and the emission angle of the second waveguide is parallel to the user's right eye line of sight.

[0078] When users with different head circumferences wear the AR glasses 1, the temples 12 will be deformed to different degrees along the first direction X, thereby causing the frame 11 to be deformed along the second direction Y. In this embodiment, the first direction X is the length direction of the AR glasses 1, and the second direction Y is the width direction of the AR glasses 1.

[0079] Specifically, Figure 2 As shown, Figure 2 for Figure 1 In the structural schematic diagram of the AR glasses 1 in another usage state, when a user with a larger head circumference uses the AR glasses 1, the user's head spreads the two temples 12, causing the first temple 121 to rotate leftward along the first direction X, and driving the first optical machine connected to the first temple 121 to rotate leftward along the first direction X. At this time, the angle of the incident light emitted by the first optical machine and irradiated to the first waveguide is rotated to the right relative to the first waveguide along the first direction X, thereby causing the outgoing light emitted by the first waveguide to rotate leftward along the first direction X, resulting in the outgoing light emitted by the first waveguide being not parallel to the user's left eye line of sight. At the same time, the second temple 122 of the AR glasses 1 will rotate to the right along the first direction X, and drive the second optical machine connected to the second temple 122 to rotate to the right along the first direction X. At this time, the angle of the incident light emitted by the second optical machine and irradiated to the second waveguide will be rotated to the left relative to the second waveguide along the first direction X, so that the outgoing light emitted by the second waveguide will rotate to the right along the first direction, causing the outgoing light emitted by the second waveguide to be not parallel to the user's right eye line of sight, and then causing the reflected light emitted by the first waveguide and the second waveguide to be not parallel to the human eye line of sight, causing the user's eyes to be unable to normally fuse the images reflected by the two waveguides into a complete image, affecting the effect of the AR glasses 1.

[0080] To solve this technical problem, the present application embodiment provides an AR glasses 1, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of the AR glasses 1 provided in the present application in another specific embodiment, wherein the AR glasses 1 include temples 12, a frame 11, an optical engine 13, and a waveguide. Along the first direction X, the frame 11 includes a first temple 111 and a second temple 112 that are symmetrically arranged, the temples 12 include a first temple 121 and a second temple 122 that are symmetrically arranged, the first temple 121 is provided with a first optical engine 131, the second temple 122 is provided with a second optical engine 132, the first frame 111 is provided with a first waveguide corresponding to the first optical engine 131, and the second frame 112 is provided with a second waveguide corresponding to the second optical engine 132.

[0081] The AR glasses 1 further include a transmission assembly 14, which connects the frame 11 and the optical engine 13, and is used to drive the optical engine 13 to rotate to an initial position through the transmission assembly 14 when the two frames 11 rotate relative to each other. The initial position of the optical engine 13 is the position when the frame 11 does not rotate relative to each other.

[0082] Specifically, the transmission assembly 14 is configured such that when the two lens frames 11 rotate relative to each other, the transmission assembly 14 can drive the optical engine 13 to rotate in a direction opposite to the rotation direction of the lens frames 11 .

[0083] In a specific embodiment, Figure 3 As shown, the first lens frame 111 and the second lens frame 112 both include a first connection end 115 and a second connection end 116 that are arranged opposite to each other along the first direction X, and the first connection end 115 of the first lens frame 111 and the first connection end 115 of the second lens frame 112 are close to each other, and the second connection end 116 of the first lens frame 111 and the second connection end 116 of the second lens frame 112 are far away from each other. The transmission assembly 14 includes a driving wheel 141, a first driven wheel 142 and a second driven wheel 143, the first connection end 115 of the first lens frame 111 and the first connection end 115 of the second lens frame 112 are both provided with the driving wheel 141, and the driving wheels 141 of the two are meshed with each other, the second connection end 116 of the first lens frame 111 and the second connection end 116 of the second lens frame 112 are both provided with the first driven wheel 142, the first optical machine 131 and the second optical machine 132 are both fixedly connected with the second driven wheel 144, and the two first driven wheels 142 and the two second driven wheels 143 are respectively meshed. At the same time, the transmission assembly 14 also includes a transmission member 144, which connects the driving wheel 141 and the first driven wheel 142 of the same transmission assembly 14. When the driving wheel 141 rotates, the transmission member 144 can drive the first driven wheel 142 to rotate, thereby driving the second driven wheel 143 engaged therewith to rotate, and then driving the optical machine 13 connected to the second driven wheel 143 to rotate, and the rotation directions of the driving wheel 141 and the second driven wheel 143 are opposite.

[0084] In this embodiment, the driving wheel 141 , the first driven wheel 142 , and the second driven wheel 143 have the same number of teeth, and the driving wheel 141 , the first driven wheel 142 , and the second driven wheel 143 have the same module.

[0085] Please also refer to Figure 4 , Figure 4 for Figure 3In the structural diagram of the AR glasses 1 in another use state, when a user with a larger head circumference uses the AR glasses 1, the user's head spreads the two temples 12, causing the first temple 121 to rotate to the left along the first direction X, and the second temple 122 to rotate to the right along the first direction X, thereby causing the outgoing light emitted by the first waveguide to rotate to the left along the first direction X, and the outgoing light emitted by the second waveguide to rotate to the right along the first direction X. At this time, the first connecting end 115 on the first frame 111 rotates downward along the second direction Y driven by the first temple 121, and the first connecting end 115 on the second frame 112 rotates downward along the second direction Y driven by the second temple 122, so that the driving wheels 141 meshing with each other at the two first connecting ends 115 both rotate. The driving wheel 141 at the first connecting end 115 of the first lens frame 111 rotates clockwise, and the first driven wheel 142 at the second connecting end 116 of the first lens frame 111 rotates clockwise through the transmission member 144, thereby driving the second driven wheel 143 meshing therewith to rotate counterclockwise, so that the first optical machine 131 rotates leftward along the first direction X. Due to the total reflection characteristic of the waveguide, the angle of the incident light of the first optical machine 131 and the angle of the outgoing light from the first waveguide rotate in opposite directions, and the rotation angles are the same, thereby causing the outgoing light emitted by the first waveguide to rotate rightward along the first direction X to be parallel to the line of sight of the left eye. At the same time, the driving wheel 141 at the first connecting end 115 of the second frame 112 rotates counterclockwise, and the first driven wheel 142 at the second connecting end 116 of the second frame 112 rotates counterclockwise through the transmission member 144, thereby driving the second driven wheel 143 meshing therewith to rotate clockwise, so that the second optical machine 132 rotates rightward along the first direction X. Due to the total reflection characteristics of the waveguide, the angle of the incident light of the second optical machine 132 and the angle of the outgoing light from the second waveguide rotate in opposite directions, and the rotation angles are the same, thereby causing the outgoing light emitted by the second waveguide to rotate leftward along the first direction X to be parallel to the line of sight of the right eye.

[0086] In this embodiment, by setting the transmission component 14, when users with different head widths use the AR glasses 1, after the two frames rotate relative to each other, the transmission component 14 can drive the optical machine 13 to rotate in the direction opposite to the rotation direction of the frame 11, so that when different users use it, the angle of the waveguide emitted light can be adjusted to be roughly parallel to the user's binocular line of sight, so that the user's eyes can fuse the images reflected by the two waveguides into a complete image, thereby improving the applicability of the AR glasses 1. In addition, the transmission component 14 can automatically adjust the angle of the optical machine 13 without manual adjustment, which simplifies the operation steps and further improves the convenience of the AR glasses 1.

Therefore, when the driving wheel 141 rotates, the second gear 1446 connected thereto can be driven to rotate, and when the first gear 1443 rotates, the first driven wheel 142 connected thereto can be driven to rotate.

[0089] Meanwhile, the connecting rod 1441 is provided with a first rack 1442 and a second rack 1447. The first rack 1442 is meshed with the first gear 1443, and the second rack 1447 is meshed with the second gear 1446. When the driving wheel 141 rotates by a first angle, it can drive the second gear 1444 connected thereto to rotate by a first angle, and make the connecting rod 1441 meshed therewith move along the first direction X, so that the first gear 1443 meshed therewith rotates by a first angle, the first gear 1443 drives the first driven wheel 142 connected thereto to rotate by a first angle, and the first driven wheel 142 drives the second driven wheel 143 meshed therewith to rotate by a first angle, and then the driving wheel 141 and the first driven wheel 142 are synchronously rotated by a first angle, so that the frame and the optical machine rotate by a first angle in opposite directions, and the optical machine rotates toward the direction of the initial position.

[0092] In a specific embodiment, Figure 5 As shown, the diameter of the first gear 1443 is smaller than the diameter of the first driven wheel 142. Figure 6As shown, the diameter of the second gear 1446 is smaller than the diameter of the driving wheel 141, thereby providing a placement space for the connecting rod 1441, so that after the first rack 1442 of the connecting rod 1441 is engaged with the first gear 1443 and the second rack 1447 is engaged with the second gear 1446, the connecting part of the connecting rod 1441 and the first gear 1443 and the second gear 1446 does not protrude from the driving wheel 141 and the first driven wheel 142, avoiding interference with other components that affect the mutual rotation between the linkage components 14.

[0093] In a specific embodiment, Figure 6 As shown, a connecting portion 114 is provided at the connection between the first lens frame 111 and the second lens frame 112 . The connecting portion 114 has a receiving space, and a part of the structure of the driving wheel 141 is received in the receiving space of the connecting portion 114 .

[0094] In this embodiment, the connecting portion 114 connects the first frame 111 and the second frame 112, and the connecting portion 114 has a accommodating space, which can provide a placement space for the two meshing driving wheels 141 at the connection between the first frame 111 and the second frame 112, and can provide protection for the two driving wheels 141 to avoid direct contact between the two driving wheels 141 and the outside world, thereby extending their service life.

[0095] In a specific embodiment, Figure 7 As shown, Figure 6 This is a schematic diagram of the structure of the AR glasses 1 provided in the present application in another specific embodiment, wherein the transmission member 144 includes at least two connecting rods, both ends of which are respectively connected to the driving wheel 141 and the first driven wheel 142, and at least two connecting rods are respectively located on both sides of the rotation center of the driving wheel 141 and the rotation center of the first driven wheel 142, so that when the driving wheel 141 rotates clockwise, the first driven wheel 142 can be driven to rotate counterclockwise through each connecting rod, and when the driving wheel 141 rotates counterclockwise, the first driven wheel 142 can also be driven to rotate clockwise through each connecting rod.

[0096] In such Figure 7 In the illustrated embodiment, the transmission member may include a first connecting rod 1444 and a second connecting rod 1445, which are located on both sides of a line connecting the rotation center of the first driven wheel 142 and the rotation center of the driving wheel 141. The first connecting rod 1444 and the second connecting rod 1445 are flexible connecting rods.

[0097] In this embodiment, the driving wheel 141 and the first driven wheel 142 of the first frame 111 can be connected by the first connecting rod 1444 and the second connecting rod 1445, and the driving wheel 141 and the first driven wheel 142 of the second frame 112 can be connected by the first connecting rod 1444 and the second connecting rod 1445. The first connecting rod 1444 and the second connecting rod 1445 are distributed along the second direction Y. When the driving wheel 141 on the first frame 111 rotates clockwise, the first connecting rod 1444 can pull the first driven wheel 142 on the first frame 111 to rotate clockwise, and when the driving wheel 141 on the first frame 111 rotates counterclockwise, the second connecting rod 1445 can pull the first driven wheel 142 on the first frame 111 to rotate counterclockwise. When the driving wheel 141 on the second frame 112 rotates clockwise, the second connecting rod 1445 can pull the first driven wheel 142 on the second frame 112 to rotate clockwise, and when the driving wheel 141 on the second frame 112 rotates counterclockwise, the first connecting rod 1444 can pull the first driven wheel 142 on the second frame 112 to rotate counterclockwise. In this embodiment, the flexible first connecting rod 1444 and the second connecting rod 1445 are provided as the transmission member 144, which can simplify the structure of the AR glasses 1, improve portability, and reduce the production and assembly costs of the AR glasses 1.

[0098] In a specific embodiment, the first connecting rod 1444 and the second connecting rod 1445 can be metal wires or elastic ropes, and the first connecting rod 1444 and the second connecting rod 1445 can provide tension, so that the driving wheel 141 can drive the first driven wheel 142 to rotate through the first connecting rod 1444 and the second connecting rod 1445. Both the metal wire and the elastic rope have good strength, which reduces the possibility of breakage during use and improves the safety and service life of the AR glasses 1. At the same time, the metal wire and the elastic rope are light in weight and small in size, which can reduce the overall size of the AR glasses 1, reduce costs, and improve the portability of the AR glasses 1.

The first distance is different from the second distance, and the third distance is different from the fourth distance. That is, the connection positions of the first connecting rod 1444 and the second connecting rod 1445 with the driving wheel 141 are staggered along the first direction X, and the connection positions of the first connecting rod 1444 and the second connecting rod 1445 with the first driven wheel 142 are staggered along the first direction X, so that one of the first connecting rod 1444 and the second connecting rod 1445 drives the first driven wheel 142 to rotate clockwise, and the other drives the first driven wheel 142 to rotate counterclockwise.

[0100] In a specific embodiment, Figure 8 As shown, Figure 8 for Figure 3 In the side cross-sectional view, the AR glasses also include a lens 17, which is connected to the frame 11.

The first accommodating cavity 123 can provide support and protection for the optical engine 13, reduce the damage caused by direct contact between the optical engine 13 and the outside during use, and extend the service life of the optical engine 13. At the same time, the optical engine 13 is rotatably connected to the first accommodating cavity 123, so that when users with different head widths use the AR glasses, the optical engine 13 can be driven by the second driven wheel 143 to rotate relative to the temple 12 to adjust the angle of the outgoing light of the waveguide, thereby improving the applicability of the AR glasses.

[0105] In a specific embodiment, Fig. 9 As shown, the AR glasses may further include a second rotating shaft 16, on which the optical engine 13 and the second driven wheel 143 are sleeved, and are rotationally connected to the first accommodating cavity 123 via the second rotating shaft 16, so that the optical engine 13 can rotate relative to the temple 12 driven by the second driven wheel 143.

[0106] In a specific embodiment, Fig. 9 As shown, the AR glasses may further include a first rotating shaft 15 .

[0107] In this embodiment, when the transmission member includes a first gear 1443, a second gear and a connecting rod 1441, the driving wheel and the second gear 1444 at the first connecting end are sleeved on the first rotating shaft 15, and the first driven wheel 142 and the first gear 1443 at the second connecting end are sleeved on the first rotating shaft 15, and the driving wheel, the first driven wheel 142 and the gear 1443 at the first connecting end and the second connecting end are rotatably connected to the bottom wall of the second accommodating cavity 113 through the first rotating shaft 15, so that they can rotate relative to the frame 11.

[0108] In another specific embodiment, when the transmission member includes at least a first connecting rod and a second connecting rod (not shown in the figure), the driving wheel and the first driven wheel are sleeved on the first rotating shaft and are rotatably connected to the bottom wall of the second accommodating cavity through the first rotating shaft, so that they can rotate relative to the frame.

At the same time, it can prevent the user from directly contacting the transmission assembly during use, thereby improving the safety of use.

[0110] Specifically, the first driven wheel 142 , the transmission member, a partial structure of the driving wheel, and a partial structure of the second transmission wheel 143 of the transmission assembly are accommodated in the second accommodating cavity 113 .
