Binocular display AR glasses need to be imaged to ensure the normal use of AR glasses. At present, the image distance of AR glasses is fixed and cannot be adjusted according to needs, and cannot adapt to different application scenarios. Summary of the invention

[0003] In view of this, the present application provides a frame assembly and an augmented reality device, which can adjust the image distance of the augmented reality device to match different application scenarios.

[0004] In a first aspect, the present application provides a frame assembly for use in an augmented reality device, comprising a first frame, a second frame, and a connecting piece connecting the first frame and the second frame, wherein a plane where the first frame is located is a first plane, a plane where the second frame is located is a second plane, and at least one of the first frame and the second frame can rotate around the connecting piece to adjust the angle between the first plane and the second plane.

[0005] In a second aspect, the present application provides an augmented reality device, comprising:

[0006] The mirror frame assembly of the first aspect;

[0007] a first optical waveguide, the first optical waveguide being carried by the first lens frame, and the first optical waveguide being used for transmitting a first optical signal incident into the first optical waveguide and coupling out to form first image information;

[0008] a second optical waveguide, the second optical waveguide being carried by the second lens frame, and the second optical waveguide being used for transmitting a second optical signal incident into the second optical waveguide and coupling out to form second image information;

[0036] The optical waveguide component 300 can transmit the optical signal incident therein, and couple out to form image information; because the two eyes receive the image information respectively, they can overlap in front of the two eyes to form a virtual image, thereby achieving the effect of augmented reality. In one embodiment of the present application, the optical waveguide component 300 includes a first optical waveguide 310 and a second optical waveguide 320.

Please refer to Figure 6, is an exploded schematic diagram of a bearing mechanism provided by another embodiment of the present application, wherein the bearing mechanism 200 includes a frame assembly 100 and a wearing assembly 201, and the wearing assembly 201 is connected to the frame assembly 100. By providing a wearing piece, the augmented reality device 500 can clamp a target object. In one embodiment of the present application, the wearing assembly 201 can be a temple assembly. Of course, the wearing assembly 201 can also be other structures that enable the augmented reality device 500 to clamp a target object.

[0039] In one embodiment of the present application, the augmented reality device 500 further includes a projection optical machine 400. The projection optical machine 400 projects an optical signal toward the optical waveguide component 300. The optical waveguide component 300 is used to transmit the optical signal injected into the optical waveguide, and couple out the optical signal to form image information, so that a virtual image appears in front of both eyes.

[0041] See also Figure 7 , is a cross-sectional schematic diagram of an augmented reality device provided in one embodiment of the present application, wherein the first optical machine 410 projects a first optical signal toward the first optical waveguide 310, the first optical waveguide 310 transmits the first optical signal, and couples out to form first image information; the second optical machine 420 projects a second optical signal toward the second optical waveguide 320, the second optical waveguide 320 transmits the second optical signal, and couples out to form second image information, the first image information and the second image information need to be combined to form a virtual image in front of both eyes to avoid the appearance of double images, and the combined image distance at this time is d. The inventor has found that in different application scenarios, such as when using existing augmented reality devices indoors or outdoors, the combined image distance is fixed and cannot be adjusted. However, when the augmented reality device is used indoors, the fixed combined image distance of the augmented reality device is too large (such as 6m-10m), or when the augmented reality device is used outdoors, the fixed combined image distance of the augmented reality device is too small (such as 1.5m-3m), which can easily cause visual fatigue and affect the comfort of using the augmented reality device.

[0042] Therefore, the present application provides a frame assembly 100 for use in an augmented reality device 500. Figure 8 , is an exploded schematic diagram of a frame assembly provided in one embodiment of the present application, the frame assembly 100 includes a first frame 110, a second frame 120 and a connecting member 130 connecting the first frame 110 and the second frame 120, the plane where the first frame 110 is located is the first plane, the plane where the second frame 120 is located is the second plane, at least one of the first frame 110 and the second frame 120 can rotate around the connecting member 130 to adjust the angle between the first plane and the second plane.

[0043] Combine the following Figure 7The principle of adjusting the combined image distance of the augmented reality device 500 by the frame assembly 100 provided in the present application is described. The angle between the light projected by the first optical machine 410 toward the first optical waveguide 310 and the first optical waveguide 310 is α, that is, the angle between the first optical waveguide 310 and the first optical machine 410 is α, the extension direction of the first optical machine 410 is the same as the direction of the light projected by it, that is, the angle between the first optical machine 410 and the direction perpendicular to the first optical waveguide 310 is 90°-α, the angle between the first optical waveguide 310 and the plane where the eyes are located is β, and the exit angle of the optical signal in the first optical waveguide 310 is 90°-β-γ, that is, the angle between the extension direction of the light coupled out of the optical waveguide and the optical waveguide is 90°-β-γ; according to the principle of light propagation in the optical waveguide, 90°-α=2β+γ. Therefore, according to the relationship 90°-α=2β+γ, when α does not change, γ can be changed by changing β. Since the distance between the eyes (i.e., the pupil distance) is fixed, changing γ can adjust the combined image distance d; similarly, changing the angle between the second optical waveguide 320 and the plane where the eyes are located can adjust the combined image distance d. Further, the change of the angle between the first optical waveguide 310 and the plane where the eyes are located and / or the change of the angle between the second optical waveguide 320 and the plane where the eyes are located will affect the combined image distance d, that is, the change of the angle between the first optical waveguide 310 and the second optical waveguide 320 will affect the combined image distance. Further, the first optical waveguide 310 is carried by the first lens frame 110, and the second optical waveguide 320 is carried by the second lens frame 120. When at least one of the first lens frame 110 and the second lens frame 120 moves relative to each other around the connecting member 130, the angle between the first optical waveguide 310 and the second optical waveguide 320 changes, thereby adjusting the combined image distance between the first image information and the second image information. Therefore, the augmented reality device 500 provided in the present application can adjust the image distance according to the needs of its application scenario, thereby enhancing the variability of the augmented reality device 500, effectively preventing repeated adjustment of the focal length during use, avoiding visual fatigue, improving the user's sense of use, and facilitating the widespread use of the augmented reality device 500; when the angle between the first plane and the second plane decreases, the image distance decreases; when the angle between the first plane and the second plane increases, the image distance increases.

[0044] In the present application, the first plane and the second plane can be horizontal planes or curved planes, and the angle between the first plane and the second plane is the angle at the connection between the first plane and the second plane. It can be understood that at least one of the first frame 110 and the second frame 120 can rotate around the connecting member 130 to adjust the angle between the first plane and the second plane, that is, at least one of the first frame 110 and the second frame 120 rotates toward the side close to the eyes, in other words, at least one of the first frame 110 and the second frame 120 rotates toward the direction inside the frame assembly 100.

In other words, the first connecting portion 131 can rotate relative to the second connecting portion 132, and the second connecting portion 132 can rotate relative to the first connecting portion 131. The specific connection method between the first connecting portion 131 and the second connecting portion 132 can be selected as needed, for example, the second connecting portion 132 can be engaged with the first connecting portion 131 to achieve a rotatable connection. Please refer to Fig.11 , which is another embodiment of the present application. Fig. 9 1 is an exploded schematic diagram of a connecting member, the connecting member 130 includes a first connecting portion 131, a second connecting portion 132 and a main body 133, the first connecting portion 131 is connected to the main body 133, the second connecting portion 132 is connected to the main body 133, at least one of the first connecting portion 131 and the second connecting portion 132 is rotatably connected to the main body 133, the first lens frame 110 is connected to the first connecting portion 131, and the second lens frame 120 is connected to the second connecting portion 132. In other words, the first connecting portion 131 and / or the second connecting portion 132 can rotate relative to the main body 133. The specific connection mode of the first connecting portion 131, the second connecting portion 132 and the main body 133 can be selected as needed, for example, the first connecting portion 131 can be engaged with the main body 133 to achieve a rotatable connection; the second connecting portion 132 can be engaged with the main body 133 to achieve a rotatable connection. In one embodiment of the present application, the first connecting portion 131 and the second connecting portion 132 are rotatably connected to the main body 133 respectively. In the present application, at least one of the first connection portion 131 and the second connection portion 132 is rotatably connected to the main body 133, that is, the first connection portion 131 and the second connection portion 132 can rotate relative to each other. When the first connection portion 131 rotates, it drives the first lens frame 110 to move, so that the first lens frame 110 rotates around the main body 133; when the second connection portion 132 rotates, it drives the second lens frame 120 to move, so that the second lens frame 120 rotates around the main body 133, thereby adjusting the angle between the first plane and the second plane, changing the angle between the first optical waveguide 310 and the second optical waveguide 320, and adjusting the combined image distance.

[0046] In one embodiment of the present application, the connecting member 130 also includes a limiting portion 134, which is used to abut against the first connecting portion 131 and the second connecting portion 132 when the angle between the first plane and the second plane is a preset angle to prevent relative rotation between the first frame 110 and the second frame 120. When the angle between the first plane and the second plane is a preset angle, that is, the angle between the first frame 110 and the second frame 120 is a preset angle, the angle between the first frame 110 and the first optical waveguide 310 and the angle between the second frame 120 and the second optical waveguide 320 reach the preset angle, so that the combined image distance reaches the preset distance, and the combined image distance is adjusted; at this time, the limiting portion 134 abuts against the first connecting portion 131 and the second connecting portion 132, and under the action of the force (such as friction, etc.) between the limiting portion 134 and the first connecting portion 131 and the second connecting portion 132, the positions of the first connecting portion 131 and the second connecting portion 132 are relatively fixed, so that the positions of the first frame 110 and the second frame 120 are relatively fixed, and relative rotation does not occur, so that the combined image distance of the augmented reality device 500 maintains the preset distance, ensuring the use of the augmented reality device 500.

[0047] See also Fig.12 , which is another embodiment of the present application. Fig. 9 The exploded schematic diagram of the connecting member in FIG. 1 shows a connecting member 130, wherein the connecting member 130 comprises a first connecting portion 131, a second connecting portion 132 and a limiting portion 134. The limiting portion 134 is carried by the first connecting portion 131, and when the angle between the first plane and the second plane is a preset angle, the limiting portion 134 abuts against the second connecting portion 132. It can be understood that when the limiting portion 134 abuts against the second connecting portion 132, it is still connected to the first connecting portion 131, that is, the limiting portion 134 abuts against the first connecting portion 131 and the second connecting portion 132 at the same time. Under the action of the connecting force between the limiting portion 134 and the first connecting portion 131 and the friction force between the limiting portion 134 and the second connecting portion 132, the positions of the first connecting portion 131 and the second connecting portion 132 are relatively fixed. Specifically, the limiting portion 134 can be embedded in the first connection portion 131 and connected to the first connection portion 131, or the limiting portion 134 can be arranged on the surface of the first connection portion 131 and connected to the first connection portion 131; the position and number of the limiting portion 134 in the first connection portion 131 are not limited, as long as it can abut against the second connection portion 132 and fix the first connection portion 131 and the second connection portion 132 when abutting against the second connection portion 132. The above description is based on the example that the limiting portion 134 is arranged on the first connection portion 131, the limiting portion 134 can also be arranged on the second connection portion 132, or the limiting portion 134 can be arranged on both the first connection portion 131 and the second connection portion 132, that is, the limiting portion 134 can be connected to at least one of the first connection portion 131 and the second connection portion 132.

[0048] See also Fig.13 , which is another embodiment of the present application. Fig. 9 The exploded schematic diagram of the connecting member in FIG. 1 shows a connecting member 130, wherein the connecting member 130 comprises a first connecting portion 131, a second connecting portion 132, a main body 133 and a limiting portion 134. The limiting portion 134 is carried by the main body 133. The limiting portion 134 is used to abut the first connecting portion 131 and the second connecting portion 132 when the angle between the first plane and the second plane is a preset angle, so as to prevent the first lens frame 110 and the second lens frame 120 from rotating relative to each other. When the limiting portion 134 abuts the first connecting portion 131 and the second connecting portion 132, the positions of the first connecting portion 131 and the second connecting portion 132 are relatively fixed under the action of the friction force between the limiting portion 134 and the first connecting portion 131 and the friction force between the limiting portion 134 and the second connecting portion 132. Specifically, the limiting portion 134 can be embedded in the main body 133 and connected to the main body 133, or the limiting portion 134 can be arranged on the surface of the main body 133 and connected to the main body 133; the position and number of the limiting portion 134 in the main body 133 are not limited, as long as it can abut against the first connection portion 131 and the second connection portion 132 and fix the first connection portion 131 and the second connection portion 132 when abutting against the first connection portion 131 and the second connection portion 132. The above description is based on the example that the limiting portion 134 is arranged on the main body 133. The limiting portion 134 can also be arranged on the first connection portion 131 and the second connection portion 132. When the angle between the first plane and the second plane is a preset angle, it abuts against the main body 133 to achieve the purpose of fixing the first connection portion 131 and the second connection portion 132.

[0049] In one embodiment of the present application, the lens frame assembly 100 further includes a driving unit connected to the limiting portion 134, and the driving unit is used to drive the limiting portion 134 to move so that the limiting portion 134 abuts against the first connection portion 131 and the second connection portion 132. In one embodiment of the present application, the limiting portion 134 is carried on the first connection portion 131, and the driving unit is used to drive the limiting portion 134 to move in a direction close to or away from the second connection portion 132. When the limiting portion 134 moves in a direction close to the second connection portion 132 until the limiting portion 134 abuts against the second connection portion 132, the first lens frame 110 and the second lens frame 120 are locked with each other. When the limiting portion 134 moves in a direction away from the second connection portion 132, the limiting portion 134 separates from the second connection portion 132, so that the first lens frame 110 and the second lens frame 120 can rotate relatively.
