[0056] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0057] As described in the background technology, in a near-eye display device that applies augmented reality technology, the near-eye display device includes an optical machine, a frame, and a display lens, and the optical machine and the display lens are arranged in the frame. The display lens has a user side facing the user and an environment side facing the external environment. The near-eye display device can have a set optical path, and the optical machine can emit light toward the display lens along the set optical path, and the display lens can receive light from the optical machine and emit light toward the user side along the set optical path.

[0058] When a user wears a near-eye display device, the optical machine can emit light toward the display lens. The light from the optical machine can be coupled into the display lens through elements such as a coupling-in layer, so that the light can be totally reflected at the display lens and can be coupled out through elements such as a coupling-out layer, thereby forming an image on the user's retina, allowing the user to obtain the image of the near-eye display device through the display lens.

[0059] Since the display lens is usually made of transparent material, the user can also obtain the scene on the environment side of the display lens through the display lens. That is to say, the light from the scene on the environment side of the display lens can be transmitted to the user's eyes through the display lens, so that the near-eye display device usually does not affect the user's normal work and life.

[0060] However, since the display lenses of near-eye display devices usually cannot be adjusted according to the actual needs of the user, when the user is visually impaired, when the light is totally reflected by the display lenses and propagates from the display lenses toward the user's eyes, the image formed on the user's retina has poor clarity, making the image obtained by the user from the near-eye display device unclear.

[0061] Furthermore, when users wear near-eye display devices, they often cannot wear ordinary corrective glasses, so when users obtain scenes on the display lens environment side through the near-eye display device, they will be affected by their own vision defects, and the clarity of the scene images obtained by the users on the display lens environment side will also be mixed, making near-eye display devices generally difficult to use for people with visual impairments, resulting in poor effects for some users wearing near-eye display devices.

[0062] In order to solve the above technical problems, an embodiment of the present application provides a near-eye display device, including a frame, an imaging component and a correction structure, wherein the imaging component includes an optical machine and a display lens arranged in the frame, the optical machine can emit light along a set optical path toward the display lens, the display lens can obtain the light from the optical machine and can emit light toward the user side along the set optical path, thereby forming an image on the user's retina.

[0063] When a user with visual impairment wears a near-eye display device, the mounting frame of the correction structure can be fixed to the frame so that the corrective lens of the correction structure can be set on the user side of the display lens. When the user watches the display image formed by the display lens, the corrective lens can play a certain corrective role on the user's vision, thereby making the image formed by the near-eye display device on the user's retina clearer, thereby improving the viewing effect of the user wearing the near-eye display device.

[0064] Furthermore, when the user views the scene on the environment side of the display lens through the correction structure and the display lens, the display lens will not affect the user's viewing process, and the correction structure can correct the user's vision, making the scene image on the environment side of the display lens clearer for the user.

[0065] It is easy to understand that, compared with the near-eye display device in the related art that cannot be adjusted, the near-eye display device of the embodiment of the present application can replace the correction structure, and the correction structure is arranged on the user side of the display lens, so that the display lens emits light along the set light path and forms an image on the user's retina from the user side. During this process, the correction structure can adjust the light from the display lens, so that it can be suitable for different user groups through different correction structures, and the applicability of the near-eye display device is further improved.

[0066] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0067] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0068] Reference Figure 1 The near-eye display device provided in the embodiment of the present application includes a lens frame 100 and an imaging assembly. The lens frame 100 can provide certain support for the imaging assembly, so that each component in the imaging assembly can be installed on the lens frame 100, so that each component in the imaging assembly can maintain a relatively stable position relationship.

[0069] The imaging assembly may include an optical engine 300 and a display lens 200 disposed in the frame 100. The near-eye display device may have a set optical path, and the optical engine 300 may emit light along the set optical path toward the display lens 200. The display lens 200 has a user side facing the user and an environment side facing the external environment, and the display lens 200 may receive light from the optical engine 300 and emit light along the set optical path toward the user side.

[0070] Exemplarily, the imaging assembly may further include structures such as an in-coupling layer (not shown in the figure) and an out-coupling layer (not shown in the figure) disposed on the display lens 200. The display lens 200 can serve as a mounting base for structures such as the in-coupling layer and the out-coupling layer, so that the in-coupling layer and the out-coupling layer do not need to be assembled by separately setting a structure.

[0071] The display lens 200 can be configured as a waveguide structure. The waveguide structure can receive light from the coupling-in layer and make the light reflect multiple times in the waveguide structure, so that the light is coupled out through the coupling-out layer and can propagate from the user side toward the user's eyes along a set optical path.

[0072] When a user wears a near-eye display device, the optical engine 300 can emit light toward the display lens 200. The light from the optical engine 300 can be coupled into the display lens 200 through elements such as a coupling-in layer, so that the light can be totally reflected at the display lens 200 and can be coupled out through elements such as a coupling-out layer, thereby forming an image on the user's retina, allowing the user to obtain an image of the near-eye display device through the display lens 200.

[0073] Reference Figure 2 and Figure 3 In some possible implementations, the correction structure 400 may include a mounting frame 410 and a correction lens 420, wherein the correction lens 420 is disposed on the mounting frame 410. The mounting frame 410 may be detachably connected to the frame 100, so that the mounting frame 410 can be fixed to the frame 100 or removed from the frame 100, so that the correction structure 400 can be disassembled and replaced through the mounting frame 410.

[0074] When the mounting frame 410 is fixed to the frame 100, the corrective lens 420 can be located on the user side of the display lens 200. When light travels from the user side of the display lens 200 toward the user's eyes along a set optical path, the light can first pass through the corrective lens 420, so that the light can enter the user's eyes after being adjusted by the corrective lens 420.

[0075] When a user with visual impairment wears a near-eye display device, the mounting frame 410 of the correction structure 400 can be fixed to the frame 100, so that the correction lens 420 of the correction structure 400 can be set on the user side of the display lens 200. When the user watches the display image formed by the display lens 200, the correction lens 420 can play a certain corrective role on the user's vision, thereby making the image formed by the near-eye display device on the user's retina clearer, thereby improving the viewing effect of the user wearing the near-eye display device.

[0076] Furthermore, when the user views the scene on the environment side of the display lens 200 through the correction structure 400 and the display lens 200, the display lens 200 will not affect the user's viewing process, and the correction structure 400 can correct the user's vision, allowing the user to view the scene image on the environment side of the display lens 200 more clearly.

[0077] Exemplarily, the corrective lens 420 can be set as a refractive lens, such as a myopia lens, a hyperopia lens, and an astigmatism lens. The type of the corrective lens 420 can be adjusted according to the actual needs of the user, and the correction structure 400 can be detachably arranged on the frame 100, which also makes it more convenient to replace the corrective lens 420.

[0078] It should be noted that due to the limitations of the material of the display lens 200 and the principle of light propagation, the light from the display lens 200 usually needs to be emitted from the user side of the display lens 200. The corrective structure 400 in the embodiment of the present application is arranged on the user side of the display lens 200, so that the light from the display lens 200 can pass through the corrective lens 420 into the user's eyes, so that the corrective lens 420 can adjust the light from the display lens 200.

[0079] Alternatively, when the correction structure 400 is disposed on the environment side of the display lens 200, when the user views the scene on the environment side of the display lens 200 through the correction structure 400 and the display lens 200, the correction lens 420 can correct the user's vision. However, when the user needs to obtain an image from the near-eye display device, the light from the display lens 200 is incident on the user's eye along the set optical path from the user side, so that the light does not pass through the correction lens 420, and the correction lens 420 cannot regulate the light, so that the user sees the image of the near-eye display device with poor clarity.

[0080] Reference Figure 2-Figure 5 In some possible implementations, the frame 100 may be arranged around the periphery of the display lens 200, so that the frame 100 can play a certain role in limiting and fixing the display lens 200, making the structure of the display lens 200 more stable.

[0081] Exemplarily, the spectacles frame 100 may be provided with at least one connecting portion 130. The mounting frame 410 may be provided with at least one matching portion 411, the matching portion 411 is provided corresponding to the connecting portion 130, and the matching portion 411 is detachably connected to the corresponding connecting portion 130.

[0082] It should be noted that the number of the connecting parts 130 can be the same as the number of the matching parts 411 , the connecting parts 130 can be arranged in a one-to-one correspondence with the matching parts 411 , and each matching part 411 can be connected to the corresponding connecting part 130 , or removed from the corresponding connecting part 130 .

[0083] When the connecting portion 130 and the corresponding matching portion 411 are connected, the connecting portion 130 and the matching portion 411 are fixed, so that the mounting frame 410 can be fixed to the frame 100; when the connecting portion 130 and the corresponding matching portion 411 are offset, the connecting portion 130 and the matching portion 411 are separated, so that the mounting frame 410 can be removed from the frame 100.

[0084] Alternatively, the number of the connecting parts 130 may be different from the number of the matching parts 411. For example, one connecting part 130 may be arranged correspondingly to one or more matching parts 411, or one matching part 411 may be arranged correspondingly to one or more matching parts 411, as long as the stability of the connection between the frame 100 and the mounting frame 410 can be ensured.

[0085] For example, the number of mating parts 411 can be greater than the number of connecting parts 130, or the number of mating parts 411 can be less than the number of connecting parts 130, so that the correspondence between the connecting parts 130 and the mating parts 411 is more flexible, and the molding process of the connecting parts 130 and the mating parts 411 can be adjusted according to the corresponding frame 100 and mounting frame 410, which also makes the preparation process of the frame 100 and the mounting frame 410 more convenient.

[0086] Exemplarily, there may be multiple connecting parts 130 and multiple matching parts 411 . Multiple connecting parts 130 may be arranged in one-to-one correspondence with multiple matching parts 411 . Each connecting part 130 may be connected to a corresponding connecting part 130 or removed from a corresponding connecting part 130 .

[0087] A plurality of connecting parts 130 may be arranged around the periphery of the display lens 200, and the plurality of connecting parts 130 may be arranged in sequence and spaced apart. When the connecting parts 130 are connected to the corresponding matching parts 411, the mounting frame 410 can be fixed to the frame 100, and when the connecting parts 130 are not connected to the corresponding matching parts 411, the mounting frame 410 can be separated from the frame 100.

[0088] It should be noted that the shape of the frame 100 can be non-circular, that is, when there are multiple connecting parts 130 and matching parts 411, the multiple matching parts 411 usually need to accurately correspond to the multiple connecting parts 130 so that the mounting frame 410 can be fixed to the frame 100. When the matching part 411 does not correspond to the connecting part 130, the mounting frame 410 will not be fixed to the frame 100.

[0089] The plurality of connection parts 130 are arranged around the periphery of the frame 100 , and the corresponding arrangement of the plurality of matching parts 411 and the plurality of connection parts 130 can play a certain positioning and guiding role, making the connection between the mounting frame 410 and the frame 100 more convenient.

[0090] In some possible implementations, the matching mode between the matching portion 411 and the connecting portion 130 can be adjusted according to the use requirements. For example, the matching portion 411 can be fixed to the connecting portion 130 by means of snap connection, etc., so that the connection between the matching portion 411 and the connecting portion 130 is more convenient, or the matching portion 411 can be fixed to the connecting portion 130 by screws, so that the connection between the matching portion 411 and the connecting portion 130 is more stable.

[0091] Alternatively, one of the matching portion 411 and the connecting portion 130 may be configured as a magnetic member, and the other of the matching portion 411 and the connecting portion 130 may be configured as a magnetic member or a magnetic metal, and the matching portion 411 may be used in conjunction with the corresponding connecting portion 130. When the matching portion 411 and the connecting portion 130 are fixed, the matching portion 411 and the connecting portion 130 may attract each other, so that the mounting frame 410 can be relatively fixed to the frame 100.

[0092] It is easy to understand that by setting the matching part 411 and the connecting part 130 to be fixed to each other by magnetic attraction, the disassembly process of the matching part 411 and the connecting part 130 is more convenient. The matching part 411 and the corresponding connecting part 130 are fixed by magnetic attraction, so that the matching part 411 can be more conveniently connected to the corresponding connecting part 130.

[0093] For example, when fixing the mounting frame 410 to the frame 100, the mounting frame 410 can be brought close to the frame 100 so that the multiple matching parts 411 are close to the corresponding multiple connecting parts 130. The matching parts 411 and the connecting parts 130 attract each other, and the matching parts 411 can achieve a certain correction effect with the connecting parts 130, so that the matching parts 411 can fit with the corresponding connecting parts 130, thereby realizing the connection between the mounting frame 410 and the frame 100 without carefully aligning the matching parts 411 and the connecting parts 130.

[0094] When removing the mounting frame 410 from the frame 100, the mounting frame 410 can be rotated so that the mounting frame 410 drives the multiple matching parts 411 to rotate relative to the frame 100. The multiple matching parts 411 can be offset from the corresponding connecting parts 130, so that the multiple matching parts 411 can be separated from the multiple connecting parts 130, thereby realizing the disassembly process of the mounting frame 410. By arranging the matching parts 411 and the connecting parts 130 to be fixed to each other by magnetic attraction, the disassembly process of the mounting frame 410 and the frame 100 is also made more convenient.

[0095] It should be noted that, compared with the implementation embodiment in which the matching portion 411 and the connecting portion 130 are fixed by snapping, the matching portion 411 and the connecting portion 130 are fixed to each other by magnetic attraction, and there is no need to ensure the precise alignment of the matching portion 411 and the connecting portion 130, so that the connection between the mounting frame 410 and the frame 100 is more convenient. Moreover, in the implementation embodiment in which the matching portion 411 and the connecting portion 130 are fixed by snapping, when the mounting frame 410 is removed from the frame 100, the connecting portion 130 located on the frame 100 usually needs to be protruding or recessed on the inner surface of the frame 100, thereby affecting the aesthetics of the frame 100.

[0096] Compared with the implementation method in which the matching portion 411 and the connecting portion 130 are fixed by screws, the method in which the matching portion 411 and the connecting portion 130 are fixed by magnetic attraction to each other does not need to ensure the precise alignment of the matching portion 411 and the connecting portion 130, making the connection between the mounting frame 410 and the frame 100 more convenient. In addition, the method in which the matching portion 411 and the connecting portion 130 are fixed by magnetic attraction to each other does not require additional locking parts for fastening, which also makes the structure of the mounting frame 410 and the frame 100 simpler.

[0097] Reference Figure 2 and Figure 3In some possible implementations, the frame 100 may be provided with a first embedding groove 131, and at least a portion of the connecting portion 130 may be disposed in the first embedding groove 131, so that the first embedding groove 131 can play a certain role in accommodating and fixing the connecting portion 130, and can reduce the possibility of the connecting portion 130 protruding from the frame 100.

[0098] The mounting frame 410 may be provided with a second embedding groove 412 , and at least a portion of the matching portion 411 may be provided in the second embedding groove 412 , so that the second embedding groove 412 can play a certain role in accommodating and fixing the matching portion 411 and can reduce the possibility of the matching portion 411 protruding from the mounting frame 410 .

[0099] Exemplarily, the connection portion 130 may not extend out of the notch of the first embedding groove 131. For example, one end of the connection portion 130 away from the bottom surface of the first embedding groove 131 may be flush with the surface of the frame 100, or one end of the connection portion 130 away from the bottom surface of the first embedding groove 131 may be located inside the first embedding groove 131.

[0100] The matching portion 411 may not extend out of the slot of the second embedding slot 412. For example, one end of the matching portion 411 away from the bottom surface of the second embedding slot 412 may be flush with the surface of the mounting frame 410, or one end of the matching portion 411 away from the bottom surface of the second embedding slot 412 may be located inside the second embedding slot 412.

[0101] When the mating portion 411 is fixed to the connecting portion 130, the first embedding groove 131 and the second embedding groove 412 are arranged opposite to each other, and the mounting frame 410 fits with the frame 100, thereby reducing the distance between the corrective lens 420 and the display lens 200, thereby reducing the overall thickness of the corrective structure 400 and the frame 100, making the near-eye display device lighter.

[0102] In some possible embodiments, the connecting portion 130 can be plugged into and matched with the matching portion 411 , and the connecting portion 130 and the matching portion 411 can be close to or far away from each other, so that the matching portion 411 can be plugged and fixed with the corresponding connecting portion 130 , or separated from the corresponding connecting portion 130 .

[0103] Exemplarily, the connection portion 130 may be provided with a mounting hole. The matching portion 411 is provided on a side of the mounting frame 410 facing the lens frame 100 , and when the matching portion 411 is fixed to the connection portion 130 , the connection portion 130 is inserted into the corresponding mounting hole.

[0104] Alternatively, the matching portion 411 may be provided with a mounting hole. The connecting portion 130 is provided on a side of the lens frame 100 facing the mounting frame 410 , and when the matching portion 411 is fixed to the connecting portion 130 , the matching portion 411 is inserted into the corresponding mounting hole.

[0105] It is easy to understand that by plugging the connecting part 130 into the corresponding matching part 411, the connecting part 130 and the matching part 411 can be close to or away from each other, so that multiple matching parts 411 can be synchronously close to the corresponding connecting part 130, so that multiple matching parts 411 can be synchronously plugged and matched with the corresponding connecting part 130, making the connection process between the mounting frame 410 and the frame 100 more convenient.

[0106] In some possible implementations, the distance between the corrective lens 420 and the display lens 200 is adjustable, so that the near-eye display device can be suitable for providing corrective lenses 420 of different specifications, which can further improve the display effect of the near-eye display device.

[0107] Exemplarily, a gasket may be provided on the side of the mounting frame 410 facing the frame 100, so that a gap may exist between the mounting frame 410 and the frame 100, and the width of the gap is equal to the thickness of the gasket, so that the gap between the mounting frame 410 and the frame 100 can be adjusted by replacing gaskets of different thicknesses.

[0108] It is easy to understand that the corrective structure 400 with corrective lenses 420 of different specifications and types can be provided with gaskets of different thicknesses. When the corrective structure 400 is replaced, not only the specifications and types of the corrective lens 420 can be adjusted, but also the gap between the corrective lens 420 and the frame 100 can be changed through the gasket, so that the distance between the corrective lens 420 and the display lens 200 is more appropriate, further improving the display effect of the near-eye display device.

[0109] The gasket can be fixedly arranged on the surface of the mounting frame 410 facing the frame 100, so that the structure of the gasket and the mounting frame 410 is more stable, and the molding process of the gasket and the mounting frame 410 is more convenient. Alternatively, the gasket can be detachably connected to the mounting frame 410, so that the replacement of the gasket can be more convenient.

[0110] Reference Figure 1 and Figure 6 In some possible implementations, one of the mounting frame 410 and the corrective lens 420 may be provided with a groove 413. The other of the mounting frame 410 and the corrective lens 420 may be provided with a protrusion 421, which may be detachably disposed in the groove 413.

[0111] Exemplarily, a groove 413 is provided on the inner side of the mounting frame 410, and a protrusion 421 is provided on the outer side of the corrective lens 420. The protrusion 421 can be inserted into the groove 413, so that the corrective lens 420 can be connected to the mounting frame 410 through the matching protrusion 421 and groove 413.

[0112] It is easy to understand that the position of the protrusion 421 and the corrective lens 420 can be adjusted according to actual conditions. For example, the setting position of the protrusion 421 in the thickness direction of the corrective lens 420 is adjustable.

[0113] When the distance between the corrective lens 420 and the display lens 200 needs to be adjusted, the corrective lens 420 can be removed from the mounting frame 410, and then the corrective lens 420 with protrusions 421 set at different positions can be fixed to the mounting frame 410, so that the position of the corrective lens 420 relative to 413 on the mounting frame 410 can be changed, thereby achieving the adjustment of the distance between the corrective lens 420 and the display lens 200.

[0114] In some possible implementations, the frame 100 may be provided in one piece, so that the structure of the frame 100 is more stable.

[0115] Or, refer to Figure 2 and Figure 7 The frame 100 may include an inner frame 110 and an outer frame 120 that match each other. The outer frame 120 may be arranged on the outside of the inner frame 110. For example, the outer frame 120 may face the environment side of the display lens 200, and the inner frame 110 may face the user side of the display lens 200.

[0116] The connection part 130 may be disposed on the inner frame 110 . Alternatively, the connection part 130 may be disposed on the outer frame 120 , and the connection part 130 located on the outer frame 120 may be exposed through the outer side of the inner frame 110 to reduce the influence of the inner frame 110 on the location of the connection part 130 .

[0117] Exemplarily, the inner frame 110 can be located on the user side of the display lens 200, and the inner frame 110 is provided with a first receiving groove 113, which accommodates part of the display lens 200, so that the first receiving groove 113 can play a certain supporting and fixing role on the display lens 200, so that the display lens 200 can be relatively fixed to the inner frame 110.

[0118] And / or, the outer frame 120 is located on the environment side of the display lens 200, and the outer frame 120 is provided with a second accommodating groove 121, which accommodates part of the display lens 200, so that the second accommodating groove 121 plays a certain supporting and fixing role on the display lens 200, so that the display lens 200 can be relatively fixed to the outer frame 120.

[0119] The second receiving groove 121 may be disposed opposite to the first receiving groove 113 , so that the first receiving groove 113 and the second receiving groove 121 can respectively accommodate a portion of the display lens 200 , thereby making the installation of the display lens 200 more stable.

[0120] Reference Figure 4 and Figure 7For example, the inner frame 110 may be provided with an installation opening 111, and the installation opening 111 may be connected to the first receiving groove 113. At least part of the optical engine 300 is inserted into the installation opening 111, and the light-emitting side of the optical engine 300 is directed toward the display lens 200 through the installation opening 111, so that the inner frame 110 can play a certain role in limiting the optical engine 300, so that the optical engine 300 can emit light toward the display lens 200 along the set light path.

[0121] Exemplarily, the inner frame 110 may be provided with a fixing frame 112 which forms an installation cavity for accommodating the optical engine 300 , so as to provide a certain support and fixation effect on the optical engine 300 through the fixing frame 112 , thereby reducing the possibility of separation between the optical engine 300 and the inner frame 110 .

[0122] Reference Figure 4 , Figure 7-Figure 9 The outer frame 120 may be provided with a limiting frame 122, and the fixing frame 112 may be provided in the limiting frame 122. At least a portion of the fixing frame 112 abuts against the limiting frame 122, so that the limiting frame 122 can provide a certain support and fixation effect on the fixing frame 112, thereby reducing the possibility of the fixing frame 112 moving relative to the outer frame 120.

[0123] In some possible implementations, the near-eye display device may further include a temple 500. A first end of the temple 500 is rotatably disposed on the frame 100, and a connector is disposed on a second end of the temple 500.

[0124] The optical machine 300 has a conducting wire, which passes through the first end of the temple 500 and is arranged on the inner side of the temple 500. The end of the conducting wire away from the optical machine 300 can be electrically connected to an external circuit through a connector, so that the conducting wire of the optical machine 300 can be accommodated by the temple 500, so that the conducting wire can be hidden on the inner side of the temple 500, reducing the possibility of the conducting wire being exposed, thereby reducing the possibility of the conducting wire being damaged.
