The mounting frame 11 is formed at an edge of the first optical waveguide 12. In an embodiment, the mounting frame 11 may also be a semi-ring structure formed on an edge of the first optical waveguide 12, such as an upper edge of the first optical waveguide 12.

The camera mounting portion 113 may be located between the connecting member 30 and the first pivoting portion 111. The position of the camera mounting portion 113 can be adjusted according to actual conditions.

Referring to fig. 1, 2 and 3, the first optical waveguide 12 may be a planar grating waveguide such as a diffraction grating waveguide. The first optical waveguide 12 may include a light coupling inlet portion 121 and a light coupling outlet portion 122.

The light coupling outlet 122 is provided inside the mounting frame 11 and may be directed toward the eye of the wearer, for example, the left eye, when the head-mounted device 100 is worn by the user.

Referring to fig. 2, fig. 3, fig. 4 and fig. 5, fig. 4 is a schematic view similar to fig. 1, which discloses a structural diagram of another view of the head-mounted device 100 according to an embodiment of the present application. Fig. 5 discloses a schematic structural diagram of the first light redirecting element 13 in an embodiment of the present application. The first light redirecting member 13 may be fixed at the mounting portion 112 and correspond to the light coupling inlet portion 121 of the first optical waveguide 12 for receiving incident light to redirect and redirect the incident light to the light coupling inlet portion 121 for light to enter the first optical waveguide 12. Specifically, the first light redirecting element 13 may be fixed to the mounting portion 112 by means of glue bonding or the like. The first light turning member 13 and the first pivot portion 111 are located on the same side of the mounting frame 11. The first light turning member 13 may be a plane mirror (also referred to as a mirror), a prism (such as a reflecting prism), or the like capable of changing the propagation direction of light rays by reflection.

Referring to fig. 4, 5 and 6, fig. 6 discloses a schematic structural diagram of a first light diverting member 13 according to another embodiment of the present application. Taking the first light redirecting element 13 as a reflective prism as an example, the first light redirecting element 13 may be a triangular prism, which may also be referred to as a primary reflective prism, and may include an incident surface 131, a reflective surface 132, and an exit surface 133. Specifically, the exit surface 133 faces the optical coupling inlet portion 121, and is connected to the reflection surface 132 and the incident surface 131 in this order. The cross sections of the incident surface 131, the reflecting surface 132, and the exit surface 133 may be isosceles right triangles (may also be referred to as total reflection prisms). Specifically, the reflecting surface 132 is disposed to be inclined at 45 degrees with respect to the incident surface 131 and the exit surface 133, i.e., an angle α therebetween is 45 degrees. Further, the incident surface 131 and the exit surface 133 are perpendicular to each other. The incident light enters from the incident surface 131, is reflected by the reflecting surface 132 to change the propagation direction of the light, and then further exits from the exit surface 133 and enters the light coupling inlet 121.

Referring to fig. 5, 6 and 7, fig. 7 discloses a schematic structural diagram of a first light diverting member 13 according to another embodiment of the present application. In practical applications, due to the requirement of the incident light, the reflection surface 132 is inclined with respect to the horizontal direction, and the first light diverting member 13 is in an asymmetric structure in the reflection direction of the light via the reflection surface 132, so that the actual optical area of the side of the reflection surface 132 away from the incidence surface 131 is smaller than that of the side close to the incidence surface 131, so that the part of the reflection surface 132 away from the incidence surface 131 can reflect the light only a little or even not, that is, the contribution of the part to the reflection of the light is very small or even not. The edge angle of the first light redirecting element 13 far away from the incident surface 131 is cut away to form the first light redirecting element 13 as shown in fig. 7, so that the thickness of the first light redirecting element 13 in the direction perpendicular to the incident surface 131 can be reduced while the redirecting effect of the first light redirecting element 13 on incident light is not affected, and the light, the weight and the size of the head-mounted device 100 are facilitated;

referring to fig. 7, the first light turning member 13 is a rectangular prism, which includes an incident surface 131, a reflecting surface 132 and an exit surface 133 of the triangular prism, and further includes a backlight surface 134 disposed between the reflecting surface 132 and the exit surface 133 and parallel to and opposite to the incident surface 131. The distance between the backlight surface 134 and the incident surface 131 may be in a range of 4.8-5.0mm, specifically, 4.8mm, 4.85mm, 4.9mm, 4.95mm, 5.0mm, and the like. The first light diverter 13 formed by the incident surface 131 and the backlight surface 134 arranged according to the distance range has a moderate volume, so that the head-mounted device 100 with a more compact and miniaturized structure can be formed, and more requirements of consumers can be met.

It should be noted that the above description is not intended to limit the structure of the first light diverting member 13, for example, the reflecting surface 132 may be inclined with respect to the incident surface 131 by other degrees, such as 30 degrees, 60 degrees, etc.; the incident surface 131 and the exit surface 133 may not be perpendicular, such as being inclined at 80 degrees or 90 degrees; the backlight surface 134 may not be parallel to the entrance surface 131, etc., as long as it is sufficient that the light rays diverted by the first light diverting member 13 can be received by the light coupling inlet portion 121; meanwhile, the first light diverting member 13 may also be other reflecting prisms, such as a double reflecting prism, a triple reflecting prism, a quadruple reflecting prism, and the like.

Further, the reflecting prism may be made of a material having relatively good light transmittance such as glass or plastic, and a light reflecting material such as silver may be coated on the surface of the reflecting surface 132 of the reflecting prism to enhance reflection of incident light. Further, when the reflecting prism is made of a brittle material such as glass, a hardened layer can be formed on the surfaces of the incident surface 131, the reflecting surface 132, the exit surface 133, the backlight surface 134, and the like by hardening the reflecting prism, thereby improving the strength of the first light redirecting member 13. The hardening treatment may be performed by penetrating lithium ions, or by attaching a film to each surface of the reflecting prism without affecting the light conversion of the first light redirecting part 13.

It should be further noted that the number of the first light diverting members 13 can be specifically set according to actual requirements, and is not specifically limited herein.

In an embodiment, a housing may be disposed outside the first light diverting member 13 to enclose the first light diverting member 13, so as to protect the first light diverting member 13 and prevent external light from affecting the light inside the first light diverting member 13.

Fig. 9 discloses a schematic structural diagram of the second light diverting member 23 in an embodiment of the present application. The second light redirecting member 23 may be fixed at the mounting portion 212 and correspond to the light coupling inlet portion 221 of the second optical waveguide 22 for receiving incident light to redirect and redirect the incident light to the light coupling inlet portion 221 for light to enter the second optical waveguide 22.

Referring to fig. 8, 9 and 10, fig. 10 discloses a schematic structural diagram of a second light redirecting element 23 in another embodiment of the present application. The second light diverting member 23 may be a triangular prism, and the second light diverting member 23 may include an incident surface 231, a reflecting surface 232, and an exit surface 233.

The second light turning member 23 may be a quadrangular prism, which further includes a backlight surface 234 disposed between the reflection surface 232 and the exit surface 233 and disposed parallel to and opposite to the incidence surface 231, in addition to the incidence surface 231, the reflection surface 232 and the exit surface 233 of the aforementioned triangular prism.

In an embodiment, a housing may be disposed outside the second light diverting member 23 to enclose the second light diverting member 23, protect the second light diverting member 23, and prevent external light from affecting the light in the second light diverting member 23.

The cameras 24 may include one or more of a Time of flight (TOF) camera, an RGB camera, and two fisheye cameras. Of course, the camera 24 may be other types of cameras, and may be specifically adjusted according to actual needs.

In one embodiment, the head-mounted device 100 may omit the first optical display 10 or the second optical display 20, or may replace the first optical display 10 or the second optical display 20 with other structures.

Referring to fig. 2, a connecting member 30 is disposed between the first optical display 10 and the second optical display 20 for connecting the first optical display 10 and the second optical display 20, so that the first optical display 10 and the second optical display 20 are integrated. It may be made of the same material as the mounting frames 11, 21, or may be made of other rigid materials. In one embodiment, the connector 30 may include a connector body 31 and a camera 32. The connector body 31 may be used to contact the bridge of the wearer's nose to support the wearing body 300 when worn, and thus the connector body 31 may be provided with a nose pad structure at a side facing the bridge of the nose to contact the bridge of the nose. In one embodiment, a camera mounting portion 311 may be provided on the connector body 31 to mount the camera 32.

The cameras 32 may include one or more of a Time of flight (TOF) camera, an RGB camera, and two fisheye cameras. Of course, the camera 32 may also be other types of cameras, and may be specifically adjusted according to actual needs.

In an embodiment, the cameras mounted on the wearing body 300 may include a TOF (Time of flight, TOF) camera, an RGB camera, and two fisheye cameras. The TOF camera may include a light emitting module and a light sensing receiving module. The TOF camera may be mounted at the camera mounting portion 311. When the TOF camera works, the light emitting module is used for emitting modulated light beams, the light beams are reflected by a target object and then received by the photosensitive receiving module, and the photosensitive receiving module can obtain the flight time of the light beams in the space through demodulation, so that the distance of the corresponding target object is calculated. Thus, with a TOF camera, the shape and model of a room can be modeled when a user wears the head-mounted device 100 around, for example, the environment of the room; that is, the shape and model of the room in which the user is located can be determined by measuring the distance from each point to the head-mounted device 100 worn by the user, thereby constructing a scene. The RGB camera may be used to collect two-dimensional color images, to take color differences of images, etc., may be connected to the TOF camera and may be mounted at the camera mounting portion 311. The two fisheye cameras may be fixed to the

camera mounting portions

113, 213, respectively.

The two fisheye cameras can be mainly used for matching images. Of course, the position arrangement of the cameras is not limited to this, and can be adjusted according to actual needs. In addition, the types of the cameras are not limited to the above, and different types of cameras can be selected according to actual needs.

Adopt different cameras, different arrangement positions for the formation of image principle and effect all can be different. For example, four cameras, a TOF camera, an RGB camera, and two fisheye cameras, may complement each other; the shooting angle of the fisheye camera is large, the fisheye camera can be a wide-angle camera, and the resolution ratio of the fisheye camera can be low. The resolution ratio of the RGB camera can be higher, but the shooting angle can be smaller, and by combining the RGB camera and the fisheye camera, an image which is larger in shooting angle and clearer can be formed.

In an embodiment, the head mounted device 100 may omit some or all of the

cameras

14, 24, 32.

In particular, the processor 44 controls the operation of the head mounted device 100, for example, the processor 44 may be used to control the first optical machine 43 to project an image, and may be used to process the image captured by the

cameras

14, 24, 32, such as to perform image processing, for example, adjusting the picture quality, rendering, special effects, etc., on the image to form an image required by the processor.

Therefore, the second leg 50 will not be described in detail herein, and only the structural configuration of the second leg 50 is illustrated, and specific reference may be made to the first leg 40 for the specific structural configuration and functional matching relationship of the second leg 50. The second leg 50 may include a leg body 51, a second pivot 52, and a second optical machine 53. The second pivot portion 52 is formed at an end of the leg body 51 facing the mounting frame 21 for connecting with the first pivot portion 211, so that the leg body 51 rotates around the second pivot portion 52 and is folded toward the mounting frame 11. The second optical machine 53 is used for projecting an image in the augmented reality or virtual reality device, and may be installed at a position of the leg main body 51 near the second pivot portion 52, and may be folded and stored along with the leg main body 51. When the leg body 51 is unfolded, the projection port faces the incident surface 231 of the second light turning member 23, so that the second optical device 53 and the second light turning member 23 form a light path for transmitting light. The second optical device 53 can be connected with the battery 45 and the processor 44.

It is understood that, for the names "first optical machine", "second optical machine" and "optical machine", the present application is not limited to the above-mentioned names, and the names of the similar structures may be interchanged according to the actual situation; for example, the "first light engine" may also be referred to as a "second light engine".

In one embodiment, the inside of the leg body 51 may also be provided with electronic devices such as a battery 45 and a processor 44.

In one embodiment, the second leg 50 may omit the second light engine 53.

Referring to fig. 1, the first leg 40 and the second leg 50 are in the unfolded state, and can be mounted on the ear of the wearer through the first leg 40 and the second leg 50, and the wearing body 300 is mounted in front of the eye of the user, so that the first optical display 10 faces the left eye of the wearer, and the second optical display 20 faces the right eye of the wearer, so that the user can use the electronic device:

referring to fig. 1 and fig. 2, the first optical machine 43 projects light to the first light diverting member 13, the light is diverted by the first light diverting member 13, coupled into the first optical waveguide 12 from the optical coupling inlet part 121, guided out of the first optical waveguide 12 from the optical coupling outlet part 122, and injected into the eye of the wearer to form an image on the retina.

Referring to fig. 1 and 2, the second optical machine 53 projects light to the second light diverting member 23, the light is diverted by the second light diverting member 23, coupled into the second optical waveguide 22 from the optical coupling inlet part 221, guided out of the second optical waveguide 22 from the optical coupling outlet part 222, and injected into the eye of the wearer and imaged on the retina.

The folding portion 500 can be folded when being stored.

Referring to fig. 12, the first leg 40 can rotate around the first pivot portion 111 and the second pivot portion 42 toward the second leg 50, so that the leg body 41 can be close to the mounting frame 11, at this time, the first optical machine 43 can also move along with the first leg 40, and since the projection port of the first optical machine 43 faces the first light turning member 13, the thickness and the width of the first optical machine 43 on the surface where the first leg 40 rotates are small, and the length of the first optical machine 43 in the light projection direction is not on the surface where the first leg 40 rotates, so that the first optical machine 43 does not affect the first leg 40 to rotate and close to the mounting frame 11, and thus the folding and the storage of the first leg 40 can be completed.

Similarly, the second leg 50 can also rotate around the first pivot part 211 and the second pivot part 52 to the side of the first leg 40, so that the leg main body 51 can be close to the first leg 40, at this time, the second optical machine 53 can also move along with the second leg 50, and since the projection port of the second optical machine 53 is over against the second light turning member 23, the thickness and the width of the second optical machine 53 on the surface where the second leg 50 rotates are both small, and the length of the second optical machine 53 in the light projection direction is not on the surface where the second leg 50 rotates, so that the second optical machine 53 does not influence the rotation of the second leg 50 and close to the first leg 40, and thus the folding and the storage of the second leg 50 can be completed.

It will be appreciated that the folding order of the first leg 40 and the second leg 50 is not sequential.

When the folded and stored head-mounted device 100 is removed for wearing, the above procedure reverse operation can be directly installed, and the first support leg 40 and the second support leg 50 can be unfolded to wear the head-mounted device 100 for use.
