[0040] The following will be combined with Figures 1 to 7 to describe the near-eye display device of the present application.

[0041] The near-eye display device provided by the embodiment of the present application includes a frame 100, a housing 300, and a near-eye display device 200. The frame 100 includes a first mounting portion 110 and a second mounting portion 120, and the first mounting portion 110 and the second mounting portion 120 are spaced apart to form a receiving space. The housing 300 is provided with a light-transmitting area 330. The near-eye display device 200 is disposed inside the housing. The near-eye display device 200 includes a display module 220 and an optical module 210 disposed on the light-emitting side of the display module 220. The optical module 210 is disposed corresponding to the light-transmitting area 330. The light-emitting side of the optical module 210 faces the near-eye side of the frame 100 through the light-transmitting area 330. The optical module 210 is configured to receive light from the display module 220 and project it onto the human eye; the housing 300 is disposed inside the receiving space 101, and both ends of the housing are rotatably connected to the first mounting portion 110 and the second mounting portion 120 respectively to adjust the light-emitting direction of the optical module 210. This light-emitting direction can be understood as the direction of the relative pitch angle towards the human eye side.

[0042] The near-eye display device can be ear-hung type or head-mounted type. For example, the whole can be in the shape of a helmet, glasses or other shapes. It should be noted that the near-eye side refers to the side of the frame 100 facing the human eye when the near-eye display device is in a worn state. In contrast, when the near-eye display device is in a worn state, the side of the frame facing away from the human eye is the environmental side of the frame 100.

[0043] As Figure 2 and Figure 3 As shown, the frame 100 is provided with a notch, and the first mounting portion 110 and the second mounting portion 120 are provided at the notch. The first mounting portion 110 and the second mounting portion 120 are spaced apart to form a receiving space 101. The housing 300 is installed inside the receiving space 101, that is, the housing 300, the first mounting portion 110, and the second mounting portion 120 enclose a receiving space 101 for installing lenses, that is, an installation space.

[0044] In some embodiments, in combination with Figure 1 、 2As shown in FIGS. 5, the region of the frame 100 corresponding to the accommodation space 101 is completely hollowed out in the second direction Y, and the second direction Y can be a direction perpendicular to the first direction X. It can be understood that the region of the frame 100 corresponding to this accommodation space 101 is a complete notch and there is no frame 100, while the housing 300 is exactly located in this accommodation space 101. The side of the housing 300 facing away from the lens (the environment side) is always exposed and configured to allow receiving the rotation operation of the user. The user's finger can touch the circumference of the entire housing 300 for rotation. It can be understood that the housing 300 is integrated into the accommodation space completely hollowed out by the frame 100, which can effectively increase the area of the housing 300 that can be touched and rotated, facilitating rotation, and the housing 300 is fully integrated into the frame 100 without interfering with the lens. The housing 300 and the frame 100 form an integral body in terms of visual appearance, reducing the obtrusiveness of the housing 300.

[0045] The housing 300 has an accommodation cavity, and the near-eye display device 200 is installed in the accommodation cavity. In one embodiment, the housing includes a first housing 310 and a second housing 320, and the first housing 310 and the second housing 320 enclose to form the accommodation cavity, which is convenient for installing the near-eye display device 200.

[0046] The near-eye display device 200 includes a display module 220 and an optical module 210. The display module 220 generates light to form an image source. The optical module 210 is installed on the light-emitting side of the display module 220 through a fixing base 240, receives the light from the display module 220 and projects it to the human eye. Among them, the fixing base 240 can provide support for the optical module 210 and provide protection for the display module 220.

[0047] As Figure 4 shown, the housing is provided with a light-transmitting area 330. The light-transmitting area 330 can be a through hole on the housing 300, or a transparent or light-transmitting solid area on the housing 300. For example, a part of the housing 300 corresponding to the near-eye side or the whole housing is made of a transparent or light-transmitting material. The optical module 210 is arranged corresponding to the light-transmitting area 330. The light-emitting side of the optical module 210 faces the near-eye side of the frame 100 through the light-transmitting area 330, as Figure 1 shown. The shape of the light-transmitting area 330 can be adapted to the shape of the outer contour of the optical module 210, for example, they are similar. In other embodiments, the shape of the light-transmitting area 330 can be longer than the optical module 210.

[0048] Both ends of the housing 300 are rotatably connected to the first mounting portion 110 and the second mounting portion 120 respectively, such as by threaded connection; under the action of an external force, rotating the housing 300 can drive the optical module 210 inside the housing 300 to rotate around its own axis, adjusting the light-emitting direction of the optical module 210, so that the light projected by the near-eye display device 200 can better align with the human eye in the pitch angle, thereby facilitating the precise adjustment of the pitch angle suitable for different human eye visual fields.

[0049] In the embodiment of the present application, the housing 300 is a part of the spectacle frame 100, and the near-eye display device 200 is installed inside the housing 300, without changing the volume of the existing spectacle frame 100. The user can directly contact the housing 300 to adjust the internal near-eye display device 300, with simple operation and smooth feel.

[0050] The near-eye display device provided by the embodiment of the present application installs the housing 300 on the spectacle frame 100 through the first mounting portion 110 and the second mounting portion 120, and the housing is adapted to the spectacle frame 100; the near-eye display device 200 is installed inside the housing 300, and the light-emitting direction of the optical module 210 inside it is adjusted by rotating the housing 300, so that the light projected by the near-eye display device 200 can better align with the human eye, improving the display effect of the near-eye display device 200.

[0051] The near-eye display device provided by the embodiment of the present application further includes a first rotating member 350 and a second rotating member 360. The first rotating member 350 and the second rotating member 360 are respectively arranged at both ends in the length direction of the housing 300. The first rotating member 350 is rotatably connected to the first mounting portion 110, and the second rotating member 360 is rotatably connected to the second mounting portion 120.

[0052] In one embodiment, the first rotating member 350 is a first gear, and the second gear is provided on the first mounting portion 110. The first gear meshes with the second gear (internally or externally); similarly, the second rotating member 360 is also rotatably connected to the second mounting portion 120 through gear meshing. Rotating the housing 300 drives the optical module 210 to rotate, and further adjusts the light-emitting direction of the optical module 210. It can be understood that when the rotation stops, the housing 300 is fixed relative to the spectacle frame 100.

[0053] As Figure 4 shown, both the first rotating member 350 and the second rotating member 360 include a first rotating ring body 361 and a second rotating ring body 362. Both sides of the first rotating ring body 361 are respectively connected to the end of the housing 300 and the second rotating ring body 362. The diameter of the first rotating ring body 361 is smaller than that of the second rotating ring body 362; both the first mounting portion 110 and the second mounting portion 120 include a first rotating groove 121 matching the first rotating ring body 361 and a second rotating groove 122 matching the second rotating ring body 362, asFigure 6 As shown, the first rotating ring body 361 is embedded in the first rotating groove 121, and the second rotating ring body 362 is embedded in the second rotating groove 122.

[0054] The first rotating ring body 361 is disposed between the second rotating ring body 362 and the housing 300. The diameter of the first rotating ring body 361 is smaller than that of the second rotating ring body 362, and a limiting groove is formed between the first rotating ring body 361 and the second rotating ring body 362. The inner walls of the first mounting portion 110 and the second mounting portion 120 are provided with the first rotating groove 121 and the second rotating groove 122. The first rotating groove 121 matches the first rotating ring body 361, and the second rotating groove 122 matches the second rotating ring body 362. The first rotating groove 121 and the second rotating groove 122 extend along the circumferential direction of the first rotating portion or the second rotating portion. A limiting protrusion is formed between the first rotating groove 121 and the second limiting groove. The first rotating ring body 361 is embedded in the first rotating groove 121, the outer wall surface of the first rotating ring body 361 is attached to the inner wall surface of the first rotating groove 121, the second rotating ring body 362 is embedded in the second rotating groove 12, the outer wall surface of the second rotating ring body 362 is attached to the inner wall surface of the second rotating groove 122, and the limiting groove is embedded at the limiting protrusion, thereby restricting the positions of the first rotating ring body 361 and the second rotating ring body 362 and fixing them at a specific angle.

[0055] Furthermore, both the first mounting portion 110 and the second mounting portion 120 include a first cover plate 123 and a second cover plate 124. As Figure 3 、 Figure 5 and Figure 6 shown, the first cover plate 123 is provided with a first rotor groove and a second rotor groove, and the second cover plate 124 is provided with a third rotor groove and a fourth rotor groove. The first rotor groove and the third rotor groove enclose to form the first rotating groove 121, and the second rotor groove and the fourth rotor groove enclose to form the second rotating groove 122.

[0056] The first mounting portion 110 and the second mounting portion 120 provided by the embodiments of the present application are both formed by enclosing the first cover plate 123 and the second cover plate 124, which is convenient for installing the first rotating ring body 361 and the second rotating ring body 362, that is, during the installation process, the first cover plate 123 or the second cover plate 124 can be detached for installation.

[0057] In addition, one of the first cover plate 123 and the second cover plate 124 is provided with a limiting portion, and the other is provided with a matching portion, and the limiting portion is snap-connected to the matching portion. In one embodiment, the first cover plate 123 is provided with a limiting protrusion, and the second cover plate 124 is provided with a clamping groove, and the limiting protrusion is snapped into the clamping groove to achieve limiting. Further, the first cover plate 123 and the second cover plate 124 are fixed by fasteners to prevent the two from shifting and ensure the installation accuracy of the housing 300. In the embodiment of the present application, the first cover plate 123 and the second cover plate 124 can also be fixed by bonding.

[0058] It should be noted that the first mounting portion 110 and the second mounting portion 120 are provided with wire passing holes, and the cable passes through the wire passing holes to electrically connect the near-eye display device 200 to electrical components (such as batteries, etc.) in the temple 400.

[0059] In another embodiment, the first rotating member 350 is threadedly connected to the first mounting portion 110, and the second rotating member 360 is threadedly connected to the second mounting portion 120. At this time, the first mounting portion 110 and the second mounting portion 120 can be an integral part or a split part.

[0060] The near-eye display device 200 provided by the embodiment of the present application further includes a back plate 230, and both the display module 220 and the optical module 210 are connected to the back plate 230; the internal space of the housing 300 is larger than the volumes of the display module 220 and the optical module 210, and the back plate 230 is slidably connected to the inner wall of the housing; the optical module 210 is configured to allow movement back and forth in the first direction X of the light-transmitting area 330, where the first direction X is as Figure 1 shown, and can also be referred to as the length direction, and the second direction Y can be a direction that forms an angle or is perpendicular to the first direction X, for example, the second direction can be the height direction.

[0061] As Figure 7 shown, the back plate 230 includes a first end face and a second end face arranged oppositely, wherein the first end face is attached and connected to the display module 220, the second end face is on the side away from the display module 220, and a plurality of heat dissipation structures 250 are provided on the second end face. By providing the heat dissipation structures 250 on the second end face, the contact area between the back plate 230 and the air can be increased, thereby improving the heat dissipation efficiency of the back plate 230.

[0062] A fixing seat 240 is provided on the side of the display module 220 away from the back plate 230, a threaded hole 241 is provided on the fixing seat 240, and the optical module 210 is threadedly connected to the threaded hole 241 through a sleeve 212 thread.

[0063] Further, a slide rail 340 is provided on the inner wall surface of the housing 300. The slide rail 340 extends along the length direction of the housing 300, and the length direction of the housing 300 is the same as the length direction of the light-transmitting hole, that is, parallel to the first direction X. The back plate 230 is slidably connected to the slide rail 340. By driving the back plate 230 to move along the extending direction of the slide rail, the position of the optical module 210 in the horizontal direction can be adjusted, so as to achieve left and right adjustment. The horizontal direction is as Figure 1 shown.

[0064] The optical module 210 provided by the embodiment of the present application has a clamping portion 211. As Figure 7 shown, the clamping portion 211 is arranged corresponding to the light-transmitting area 330. The clamping portion 211 is configured to allow being clamped by an external clamping member and drive the optical module 210 to move. For example, a clamping member such as tweezers is used to clamp the clamping portion 211 to drive the optical module 210 to move. For example, a notch is provided on the optical module 210. A user can use a clamping member (such as tweezers) to clamp the optical module 210, apply an external force to drive the optical module 210 to move along the extending direction of the slide rail, and then adjust the position of the optical module 210 in the light-transmitting area 330 along the first direction X to adapt to different human eye fields of view.

[0065] In another embodiment, at least a part of the back plate 230 protrudes outside the housing. The back plate 230 is configured to allow being clamped by an external clamping member and drive the optical module 210 to move. For example, a clamping member clamps the back plate 230 to drive the optical module 210 to move. For example, a protrusion is provided on the back plate 230, and a through hole is correspondingly provided on the housing 300. The protrusion passes through the through hole and is exposed outside the housing 300, which is convenient for a clamping member to clamp or a user to hold, and then drives the optical module 210 to move along the slide rail. In one embodiment, a protrusion is provided on the side of the back plate 230 away from the optical module 210.

[0066] The near-eye display device provided by the embodiment of the present application adjusts the up and down position of the internal near-eye display device by rotating the housing, so as to adjust the light-emitting direction of the optical module 210. By driving the optical module 210 to move along the extending direction of the slide rail, the position of the optical module 210 in the horizontal direction of the spectacle frame 100 is adjusted. The present application can adapt to human eyes with different pupil distances, so that a virtual object or scene can be effectively projected onto the human eyes, improving the use effect of the near-eye display device.

[0067] The area of the light-transmitting area 330 of the near-eye display device 200 according to the embodiment of the present application along the housing 300 in the first direction X is greater than or equal to the area of the optical module 210. The first direction X is as Figure 1As shown, it can also be referred to as the length direction. Therefore, it can be ensured that the movement of the optical module 210 within the range in the first direction X of the light-transmitting area 330 still does not affect the light output of the optical module 210. In some embodiments, the light-transmitting area 330 includes a through hole provided in the housing 300, and the near-eye display device 200 further includes a transparent cover plate, and the transparent cover plate is covered at the through hole. In some embodiments, the transparent cover plate is detachably mounted at the through hole.
