[0003] At present, binocular waveguide AR glasses based on binocular vision involve binocular fusion technology in practical applications.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] The disclosure below provides many different embodiments or examples to realize the different structures of the embodiments of the present application. In order to simplify the disclosure of the embodiments of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present application. In addition, the embodiments of the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0033] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0034] In order to solve the problems in the prior art, the present application provides a binocular fusion adjustment mechanism and AR glasses. The binocular fusion adjustment mechanism can meet the needs of users in different fusion distance scenarios and improve the user experience.

[0035] like Figure 1-5 As shown, an embodiment of the present application provides a binocular fusion adjustment mechanism, which is applied to AR glasses. The AR glasses include a glasses body 1 and a projector 2 and an optical waveguide coupling area 3 arranged on the glasses body 1. The binocular fusion adjustment mechanism includes a reflection component 4, which is movably arranged on the glasses body 1. The reflection component 4 reflects the image output by the projector 2 and forms incident light. The incident light is coupled into the optical waveguide coupling area 3. The reflection component 4 can change the coupling angle of the incident light coupled into the optical waveguide coupling area 3 by changing its own angle. The coupling angle is used to indicate the degree of change of the virtual image distance corresponding to the virtual image generated by the projection image.

[0036] In the present application, the image output by the projector 2 is reflected by the reflective component 4 to form incident light. By changing the angle of the reflective component 4, the incident angle of the incident light coupled into the optical waveguide coupling zone 3 is changed, thereby changing the fusion distance, which can satisfy the user's use in different fusion distance scenes and improve the user experience. For example, in a cycling scene, a relatively far field of view is required, which also requires a relatively far fusion distance. By adjusting the angle of the reflective component 4, the fusion distance can be adjusted to a distance that matches the cycling scene to obtain a clearer and more realistic image. In a speech scene, a relatively close field of view is required, which also requires a relatively close fusion distance. By adjusting the angle of the reflective component 4, the fusion distance can be adjusted to a distance that matches the speech scene to obtain a clearer and more realistic image. Different application scenarios are not listed here one by one.

[0037] In the related technology, the actual application of binocular waveguide AR glasses currently involves binocular fusion technology. Figure 6 The figure is a schematic diagram of binocular fusion, where 3 is the left and right eye waveguide coupling area, 2 is the left and right eye projector, L is the target fusion distance, θ is the optical machine deflection angle, and W is the binocular pupil distance of the human eye. In this way, a virtual image at a distance L from the human eye appears within the binocular field of view of the observer, realizing a fused virtual image at a specific virtual image distance for observation. However, at present, an AR eye can only achieve a single fusion distance, which is suitable for a single application scenario, and cannot meet the needs of users in different fusion distance scenarios, affecting the user experience.

[0038] In the embodiment of the present application, the image output by the projector 2 is reflected by the reflective component 4 to form the incident light. By adjusting the angle of the reflective component 4, the incident angle between the incident light and the optical waveguide coupling area 3 is changed. Different incident angles will lead to different optical path differences, thereby achieving different virtual image distances. By adjusting the angle of the reflective component 4, the incident light coupling angle can be changed, so that the imaging distance of the virtual image can be adjusted; the AR glasses can adapt to the virtual image distance requirements in different scenarios, such as close-range office and long-distance viewing; compared with the solution of fixed fusion distance in the prior art, it has better flexibility and user experience. Figure 1 As shown, the angle between the reflective component 4 and the optical waveguide coupling region 3 is small, so that the fusion distance is far; Figure 2 As shown, the angle between the reflective component 4 and the optical waveguide coupling region 3 becomes smaller, so that the fusion distance becomes shorter; Figure 3As shown, the angle between the reflective component 4 and the optical waveguide coupling zone 3 is further reduced, so that the fusion distance is further shortened. Specifically, the angle between the reflective component 4 and the optical waveguide coupling zone 3 can be continuously adjusted, so that the fusion distance can be continuously adjusted, further broadening the application scenarios; the angle between the reflective component 4 and the optical waveguide coupling zone 3 can also be set to multi-level adjustment, each level corresponds to a fusion distance, so that one AR glasses can be suitable for multiple application scenarios, and the angle between the reflective component 4 and the optical waveguide coupling zone 3 can be quickly and accurately adjusted according to the fusion distance requirements of the scene, which is easy to operate and ensures accuracy.

[0039] In the present application, the AR glasses have two reflective components, one of which is matched with the left-target projector 2 and the optical waveguide coupling area 3, and the other is matched with the right-target projector 2 and the optical waveguide coupling area 3. The adjustment angles of a pair of reflective components are the same, and the reflection angles need to be complementary. Specifically, when rotating, one of the pair of reflective components rotates counterclockwise and the other rotates clockwise, but the rotation angles are the same, so that the position of the virtual image and the center position of the two lenses form an isosceles triangle.

[0040] Specifically, the movable setting includes various implementation modes such as rotatable and movable; the reflective component 4 can be an optical element capable of reflecting light, such as a plane mirror and a curved mirror; coupling refers to the process of light entering the optical waveguide, including incident modes at different angles.

[0041] Optionally, the reflective component 4 may also include a plurality of reflectors, and angle adjustment may be achieved by switching different reflective surfaces.

[0042] Optionally, the reflective component 4 may also adopt a liquid crystal adjustable light reflective surface to change the reflection angle by electrical control.

[0043] In some embodiments, the reflective component 4 can be rotatably disposed on the eyeglass body 1, and the reflective component 4 changes its own angle by rotating.

[0044] In the present application, a rotating shaft connection is set between the reflective component 4 and the eyeglass body 1. The rotating shaft can be supported by bearings to reduce friction, and an angle limit structure can be set to prevent excessive rotation. The continuous adjustment of the reflection angle can be achieved through the rotating mechanism. The adjustment accuracy is high, the operation is simple and intuitive, and it is convenient for users to precisely control. The structure is simple and reliable, the cost is low, and the service life is long.

[0045] Optionally, a ball hinge connection can be used to achieve multi-degree-of-freedom adjustment, and an elastic hinge can be used to achieve precise adjustment of small angles.

[0046] In some embodiments, the binocular fusion adjustment mechanism further includes an adjustment component 5 disposed on the eyeglass body 1 , and the adjustment component 5 is used to drive the reflection component 4 to rotate.

[0047] In the present application, the adjustment component 5 and the reflection component 4 form a transmission mechanism, and the movement of the adjustment component 5 drives the reflection component 4 to rotate. An adjustment scale can be set to facilitate precise control, thereby achieving precise control of the reflection component 4, providing a stable angle adjustment mechanism, and facilitating user operation.

[0048] Optionally, the adjustment component 5 may also adopt an electric adjustment method by adding a motor drive; or may adopt a memory alloy drive to achieve temperature control adjustment.

[0049] Optionally, the adjustment component 5 may not be provided, and the angle of the reflection component 4 may be adjusted manually.

[0050] In some embodiments, the adjustment component 5 includes: a nut 51 rotatably disposed on the eyeglass body 1 ; and a screw rod 52 , one end of the screw rod 52 is threadedly connected to the nut 51 , and the other end is connected to the reflection component 4 .

[0051] In the present application, the nut 51 is fixed on the eyeglass body 1 and can rotate around the axis. The connection between the screw rod 52 and the reflective component 4 can be hinged. The selection of the pitch of the thread pair needs to consider the adjustment accuracy requirements. The precise adjustment of small angles can be achieved through thread transmission. It has a self-locking function, stable position after adjustment, compact structure, suitable for miniaturized design of glasses, large transmission ratio, and easy precise control.

[0052] Optionally, the adjustment component 5 may also adopt a worm gear transmission mode; the adjustment component 5 may also use a differential thread mechanism to achieve higher precision adjustment.

[0053] like Figure 4 As shown, in some embodiments, the interior of the nut 51 is provided with a first internal thread structure and a second internal thread structure with the same pitch and opposite rotation direction, and the adjustment component 5 includes two screw rods 52, one end of the two screw rods 52 is threadedly connected to the first internal thread structure and the second internal thread structure respectively, and the other ends of the two screw rods 52 are respectively connected to the two reflection components 4.

[0054] In the present application, a bidirectional thread structure is adopted, and a nut 51 controls two screw rods 52 at the same time, and symmetrical movement is achieved through reverse threads to realize synchronous adjustment of the left and right eyes, ensure the synchronization and symmetry of the binocular images, simplify the operation, complete the binocular adjustment in one action, and have a compact structure and a small number of parts.

[0055] Specifically, the same pitch ensures that the adjustment amount of the left and right eyes is consistent; the opposite rotation direction achieves synchronous reverse movement.

[0056] Optionally, a differential screw mechanism is adopted, and a gear differential mechanism is used to achieve synchronous adjustment.

[0057] like Figure 5As shown, in some embodiments, the adjustment component 5 includes: a rotating member 53 rotatably disposed on the eyeglass body 1; and a connecting rod 54, one end of the connecting rod 54 is hinged to the eccentric position of the rotating member 53, and the other end is hinged to the reflection component 4.

[0058] In the present application, the rotating part 53 serves as a crank and the connecting rod 54 serves as a transmission rod. The eccentricity determines the adjustment range. The arrangement of the hinge point 531 affects the transmission effect. The crank-connecting rod 54 mechanism has a simple and reliable structure, easy operation of the rotation input, continuous and smooth movement, the articulated structure makes the movement more flexible, and the eccentric design provides the necessary movement stroke.

[0059] Specifically, a damping member may be provided at the connection between the rotating member 53 and the eyeglass body 1 so that the rotating member 53 can be stably maintained at a desired angle.

[0060] Optionally, a cam mechanism is used instead of the eccentric structure; a flexible connection is used instead of the rigid connecting rod 54 .

[0061] In some embodiments, two hinge points 531 are radially arranged on the rotating member 53, and the distance between the two hinge points 531 and the rotation center of the rotating member 53 is equal. The adjustment component 5 includes two connecting rods 54, one end of the two connecting rods 54 is respectively connected to the two hinge points 531, and the other end of the two connecting rods 54 is respectively connected to the two reflection components 4.

[0062] In the present application, the symmetrical arrangement of the double hinge points 531 and the equidistant design ensure synchronization, the parallel transmission of the double connecting rods 54 realizes the synchronous adjustment of the left and right eyes and ensures the symmetry of the movement. The single rotation input controls the binocular adjustment, the mechanism is compact, and the transmission is stable.

[0063] In some embodiments, a plurality of mounting portions for mounting the reflective component 4 are provided on the eyeglass body 1 , and the reflective component 4 is detachably provided on the mounting portion. The reflective component 4 changes its own angle by being installed on different mounting portions.

[0064] In the present application, a plurality of fixed-angle mounting positions are preset on the eyeglass body 1, and a quick disassembly and assembly structure is adopted for easy adjustment. Each mounting portion corresponds to a specific reflection angle, and a multi-level angle adjustment scheme is provided. The structure is simple, the cost is low, the adjustment is stable and reliable, and it is not easy to deviate, so it is easy to maintain and replace the reflection component 4.

[0065] Specifically, the mounting position on the eyeglass body 1 may be a slot, and the reflective component 4 is inserted into the slot. The angles of the multiple slots are different, so that when the reflective component 4 is inserted into different slots, its own angle changes.

[0066] Optionally, a magnetically fixed detachable structure may be used, using a snap-on quick installation structure.

[0067] In some embodiments, the reflective component 4 is a plane mirror or a concave mirror.

[0068] In this application, the plane mirror is suitable for simple reflection occasions, and the concave mirror can be used for beam shaping. The mirror surface needs to be treated with a high-reflectivity coating. The plane mirror provides a distortion-free reflection effect, and the concave mirror can achieve a certain beam convergence function. The two solutions are suitable for different optical design requirements, the manufacturing process is mature, and the cost is controllable.

[0069] Specifically, a plane mirror is a reflector with a flat surface; a concave mirror is a reflector with a concave curved surface.

[0070] Optionally, the reflective component 4 may also adopt an aspherical reflector, or a composite curved reflector.

[0071] The binocular fusion adjustment mechanism reflects the image output by the projector 2 through the reflection component 4 to form incident light. By changing the angle of the reflection component 4, the incident angle of the incident light coupled into the optical waveguide coupling area 3 is changed, thereby changing the fusion distance, which can meet the needs of users in different fusion distance scenarios and improve the user experience.

[0072] An embodiment of the present application provides an AR glasses, including: a glasses body 1, a projector 2 and an optical waveguide coupling area 3 arranged on the glasses body 1; and the above-mentioned binocular fusion adjustment mechanism.

[0073] In this application, the adjustment mechanism is integrated into the AR glasses to ensure the compactness of the overall structure and take into account the ease of use, thereby realizing AR glasses with adjustable fusion distance, improving the practicality and adaptability of the product and improving the user experience.
