[0057] Referring to Figures 1 to 10, in this embodiment, a near-eye display device 30 is proposed, including a shell assembly 110, which is provided with a receiving groove 1121; a display module 300, which is at least partially located in the receiving groove 1121; the display module 300 can generate image content to enter the light module 100. The optical module 32 is located in the receiving groove 1121 and on the light-emitting side of the display module 300; the optical module 32 receives the display content from the display module 300. The optical module 32 can be made of materials such as epoxy resin, glass, etc. The back panel 400 is located on the side of the shell assembly 110 away from the optical module 32; in other embodiments, the shell assembly 110 can also be understood as a component such as a bracket. In which, the shell assembly 100 includes a first shell 111 and a second shell 112, and the second shell 112 is connected to the back plate 400 to cover the accommodating groove 1121 and seal at least part of the display module 300. It can be understood that the display module 300 may include a microdisplay 311, an electrical wire 212 and a circuit board 301, etc. The electrical wire 212 may also include a first flexible electrical circuit board 33 and a second flexible circuit board 34 such as those appearing in other embodiments; wherein the microdisplay 311 is located in the accommodating groove 1121, and the electrical wire 212 can be partially exposed relative to the accommodating groove 1121, and the circuit board 301 can be located outside the accommodating groove 1121; in other embodiments, the circuit board 301 may also be located or partially located in the accommodating groove 1121, and the electrical wire 212 is at least partially exposed, and the electrical wire 212 can be electrically connected to electrical components such as a power supply and a main control board. The optical module 32 is connected to the first housing 111. A first connecting portion 1123 is provided on the exterior of the first housing 111, and a second connecting portion 1125 is provided on the interior of the second housing 112. The first connecting portion 1123 is configured to allow for connection with the second connecting portion 1125 to adjust the distance between the optical module 32 and the display module 300. The first connecting portion 1123 and the second connecting portion 1125 can be formed by threads, screws, gear racks, slides, sliders, etc. The first housing 111 and the second housing 112 can be two independent components, movably connected by the first connecting portion 1123 and the second connecting portion 1125.

[0058] It is understood that the light generated by the display module 300 passes through the optical module 32 and then enters the user's eyes. The optical module 32 is disposed in the first housing 111 and is fixed thereto, for example, using optical glue or a fastener. The display module 300 is disposed in a receiving groove between the back panel and the second housing. A first connecting portion 1123 is disposed on the outer periphery of the first housing 111, and a second connecting portion 1125 is disposed within the second housing. A movable connection is configured between the first connecting portion 1123 and the second connecting portion 1125 to adjust the distance between the optical module and the display module.

[0059] In some existing technologies, most of them directly move the optical module 32, which is likely to cause damage to the optical module 32. Instead, the optical module 32 is fixedly connected to the first shell 111, and then the relative distance between the first shell 111 and the second shell 112 is driven to indirectly drive the optical module 32 to move relative to the shell assembly 110, thereby adjusting the distance between the optical module 32 and the display module 300, effectively reducing the wear and tear on the optical module 32, thereby adjusting the imaging distance, and adapting to users with different vision, so that different users can clearly see the image content of the display module 300.

[0060] The optical module 32 also includes a light-incoming surface, a first reflecting surface, a second reflecting surface, and a light-emitting surface; the light-incoming surface is located at the first end; the first reflecting surface is located at the second end opposite to the first end; the second reflecting surface is located at the first end, and the second reflecting surface surrounds the light-incoming surface. The light-emitting surface is located at the second end, and the light-emitting surface surrounds the first reflecting surface, and the micro-display assembly faces the light-incoming surface; wherein, the optical module 32 can be a solid base structure made of a transparent or light-transmitting material, the light-incoming surface and the second reflecting surface are located at the first end of the solid base, and the first reflecting surface and the light-emitting surface are located at the second end of the solid base. In some embodiments, the optical module 32 can be a hollow structure, for example, there is a hollow structure between the first end and the second end. It can be understood that the first reflecting surface and the second reflecting surface are coated with a reflective film, such as a metal or metal alloy reflective film such as silver or aluminum. The microdisplay 311 faces the light incident surface, and the light generated by the microdisplay 311 enters from the light incident surface and is projected onto the first reflective surface, then reflected by the first reflective surface to the second reflective surface, and finally emitted from the light emitting surface, wherein the first reflective surface and the second reflective surface may include one or a combination of inclined planes, curved surfaces, spherical surfaces, aspherical surfaces or free-form surfaces, and the incident surface and the exit surface may be one or a combination of planes, curved surfaces, spherical surfaces, aspherical surfaces or free-form surfaces.

[0061] In some embodiments, the first reflective surface and the light-emitting surface can be continuous surfaces, and the light-input surface and the second reflective surface can be continuous surfaces. The continuous surfaces can be understood as being constructed by the same function. For example, they are all free-form surfaces constructed using the same Zernike polynomial function. In some embodiments, the surface formed by the first reflective surface and the light-emitting surface, and the surface formed by the light-input surface and the second reflective surface are constructed by the same function, and the two can be parallel to each other. In some embodiments, the surface formed by the first reflective surface and the light-emitting surface, and the surface formed by the light-input surface and the second reflective surface 44 are all free-form surfaces.

[0062] In some embodiments, the light-incoming surface and the first reflecting surface can both be circular, elliptical, or polygonal, etc., and the shapes of the second reflecting surface and the light-emitting surface can be polygonal, circular, elliptical, a closed shape formed by an arc + a straight edge, etc. In some embodiments, the light-incoming surface and the first reflecting surface are the same or similar. In some embodiments, the area of ​​the first reflecting surface is greater than or equal to the light-incoming surface, and the area of ​​the light-incoming surface is greater than or equal to the area of ​​the region of the microdisplay used to generate light, thereby ensuring that the light from the microdisplay can fully enter and be fully reflected and then emitted from the light-emitting surface. For other designs or structures of the optical module 32, reference can also be made to the descriptions of the relevant embodiments in the prior Chinese application numbers 2023111912240, 2024205421010, 2023115809662, or 2023115822046.

[0063] 1-9 , the second housing 112 includes a second through hole 1120, and the first housing 111 is movably disposed in the second through hole 1120. The display module 300 is mounted on the second housing 112. In this embodiment, the second housing 112 is a tubular structure.

[0064] The central axes of the first through hole 1110 and the second through hole 1120 are oriented in the same direction. Specifically, the first through hole 1110 and the second through hole 1120 can be coaxially arranged. The optical module 32 is located within the first through hole 1110 and the second through hole 1120, directly opposite the microdisplay 311 of the display module 300. The display module 300 is mounted on the second housing 112, and at least partially abuts against the back panel 400. The optical module 32 is at least partially raised above the first through hole 1110. This raised portion is opaque, facilitating subsequent user distance adjustment. This opaque portion reduces light loss and improves light extraction efficiency. In some embodiments, the maximum dimension of the optical module 32 is less than or equal to 20 mm, such as 20 mm, 18 mm, 15 mm, etc. This maximum dimension can be the maximum lateral dimension of the optical module 32, such as the end face dimension of the optical module 32, thereby facilitating the assembly of the optical module into a smaller space.

[0065] In some embodiments, the first connection portion 1123 of the first housing 111 and the second connection portion 1125 in the second through hole 1120 can be threadedly connected. Specifically, the first connection portion 1123 of the first housing 111 is located on the outer wall of the first housing 111 and is provided with external threads. The second connection portion 1125 is located on the inner wall of the second through hole 1120 and is correspondingly provided with internal threads, wherein the external threads and the internal threads are threadedly connected. When an external force drives the first housing 111 to rotate relative to the second housing 112, the threads cause the first housing 111 to move along the central axis of the second through hole 1120, thereby moving closer to or farther from the display module 300.

[0066] In other embodiments, the first connecting portion and the second connecting portion are connected by sliding. Specifically, the sliding direction of the first shell 111 relative to the second shell 112 is parallel to the center axis of the second through hole 1120, wherein a tight fit can be adopted between the first shell 111 and the second through hole 1120, and the first shell 111 slides relative to the second through hole 1120 only when sufficient external force acts directly on the first shell 111.

[0067] As shown in Figures 7 and 8, the optical module 32 includes a plug-in portion 321 and a flange 323. The plug-in portion 321 is used to be inserted into the first through-hole 1110 and is fixedly connected to the first housing 111. The flange 323 is located at one end of the plug-in portion 321. The cross-sectional area of ​​the flange 323 is larger than the cross-sectional area of ​​the first through-hole 1110. The flange 323 is raised relative to the first through-hole 1110, thereby preventing the flange 323 from being inserted into the interior of the first through-hole 1110. The flange 323 is used to achieve the installation and positioning between the plug-in portion 321 and the first housing 111. When the plug-in portion 321 is inserted into the first through-hole 1110 and the flange 323 contacts the first housing 111, the plug-in portion 321 cannot move further relative to the first housing 111, indicating that the plug-in portion 321 is properly installed.

[0068] As shown in Figures 7 and 8, an adjustment portion 3220 is provided on the outer circumference of the flange 323. The adjustment portion 3220 may be tangential to the flange 323 and is configured to drive the movement of the optical module 32. By applying a tool or finger to the adjustment portion 3220 and applying a corresponding force, the optical module 32 can be driven to move relative to the second housing 112, thereby adjusting the distance between the optical module 32 and the display module 300.

[0069] In other embodiments, the first shell 111 may further include a flange 323 and an adjustment portion 3220 provided on the flange 323. It can be understood that the optical module 32 is surrounded by the first shell 111 except for the light-emitting end face. At this time, the flange 323 of the first shell 111 is higher than the first through hole 1110, so that the first shell 111 can be directly adjusted to reduce the wear on the optical module 32. The adjustment portion 3220 is a planar structure, a convex structure or a concave structure, wherein the number of the adjustment portions 3220 is one or more. The number of the adjustment portions 3220 may include a plurality of adjustment portions spaced apart along the flange 323, for example, the adjustment portion 3220 may be a planar structure, and there are two adjustment portions 3220 arranged in parallel. For example, the user or during production can use tweezers or a clamp to adjust the adjustment portion 3220 for rotation.

[0070] As shown in Figures 4 and 8, a positioning notch 1111 is provided on the first housing 111, which is connected to the first through hole 1110. For ease of understanding, the first connecting portion 1123 is intentionally omitted in Figure 4. A positioning protrusion 3210 is provided on the outer wall of the plug-in portion 321. The positioning protrusion 3210 is used to insert into the positioning notch 1111. When assembling the optical module 32 with the first housing 111, the positioning protrusion 3210 on the plug-in portion 321 can be first aligned with the positioning notch 1111 on the first housing 111, and then the plug-in portion 321 can be inserted into the first through hole 1110. Through the action of external force, the plug-in portion 321 is continuously inserted into the first through hole 1110. When the positioning protrusion 3210 is fully inserted into the positioning notch 1111, it is indicated that the plug-in portion 321 is properly installed.

[0071] As shown in Figures 1-9, in this embodiment, a glue injection hole 1112 is provided on the first shell 111, and the glue injection hole 1112 is connected to the first through hole 1110. The glue injection hole 1112 is used to inject fixing glue to fix the first shell 111 to the optical module 32. After the optical module 32 and the first shell 111 are assembled, fixing glue is injected into the glue injection hole 1112. Since there is a certain gap between the plug-in portion 321 and the inner wall of the first through hole 1110, the injected fixing glue will flow into the gap. After the fixing glue solidifies, the first shell 111 and the optical module 32 are fixed. In some embodiments, the light of the optical module 32 is configured to not leak from the side wall of the first shell 111, and the side wall of the first shell 111 includes an opaque material. In other embodiments, the plug-in portion 321 of the optical module 32 and the first through hole 1110 of the first shell 111 can be fixedly connected by interference fit or other methods.

[0072] As shown in Figures 1-9, the display module 300 includes a microdisplay 311, electrical conductors 212, and a circuit board 301. The microdisplay 311 is mounted within a receiving slot 1121 and thermally coupled to the backplate 400. The circuit board 301 is located outside the receiving slot 1121. One side of the receiving slot 1121 is connected to a mounting notch 1122. The microdisplay 311 passes through the mounting notch 1122 via the electrical conductors 212 and is electrically connected to the circuit board 301. The microdisplay 311 is mounted within the receiving slot 1121. The receiving slot 1121 is provided on the second housing 112. The side of the microdisplay 311 facing away from the optical module 32 can be in contact with the backplate 400, thereby transferring heat from the microdisplay 311 to the backplate 400.

[0073] The microdisplay 311 may include Micro-LED (Micro Light-Emitting Diode), uLED (Micro Light Emitting Diode), Micro-oled (Micro Organic Light-Emitting Diode), LCoS (Liquid Crystal On Silicon), LCD (Liquid Crystal Display), DMD (Digital Micromirror Device) / DLP (Digital Light Processing) or LBS (Laser Beam Scanning), etc., or any combination of the above products.

[0074] In this embodiment, the microdisplay 311 is electrically connected to an electrical conductor 212. One side of the receiving slot 1121 is connected to a mounting notch 1122, which is used to accommodate the electrical conductor 212. The electrical conductor 212 can be made of a flexible material. The electrical conductor 212 is electrically connected to the circuit board 301, transmitting power from the circuit board 301 to the microdisplay 311, thereby enabling the normal operation of the microdisplay 311. The circuit board 301 includes a power supply circuit board and a power module, wherein the electrical conductor 212, the power supply circuit board, and the power module are electrically connected in sequence.

[0075] As shown in Figures 1 to 9, a back plate 400 is provided on the side of the display module 300 facing away from the optical module 32, wherein the back plate 400 covers the receiving groove 1121 and is fixedly connected to the housing assembly 110. The back plate 400 can protect the micro display 311. The housing assembly 110 also includes a fixing member 120, and the first housing 111 and the back plate 400 are respectively provided with fastening holes 4001. The fasteners 440 penetrate the fastening holes to fix the back plate 400 and the second housing 112. The back plate 400 and the second housing 112 of the housing assembly 110 can be fixedly connected by fixing members such as screws. It is convenient to assemble the micro display 311 into the receiving groove 1121. The back plate 400 can be made of a material with excellent thermal conductivity such as metal, such as copper, aluminum, etc.

[0076] As shown in Figures 10 and 11, the back panel 400 includes a first end face 410 and a second end face 420 that are arranged opposite to each other. The first end face 410 is the surface of the back panel 400 on the side close to the display module 300, wherein the first end face 410 is in contact with the micro display 311 of the display module 300, thereby dissipating heat from the micro display 311. The second end face 420 is the surface of the back panel 400 on the side away from the display module 300. A plurality of heat dissipation structures 430 are provided on the second end face 420, and may be distributed in an array. In this embodiment, the heat dissipation structure 430 protrudes from the second end face 420. In other embodiments, the heat dissipation structure 430 may be recessed into the second end face 420.

[0077] By providing the heat dissipation structure 430 on the second end surface 420, the contact area between the back plate 400 and the air can be increased, thereby improving the heat dissipation efficiency of the back plate 400. The array distribution of the heat dissipation structure 430 can make the heat dissipation of the back plate 400 more uniform, effectively reducing the occurrence of local heat accumulation.

[0078] In some embodiments, referring to Figures 1-9 , a snap-fit ​​member 1127 is further provided on the first housing 111 and / or the second housing 112. The snap-fit ​​member 1127 is configured to cooperate with another external snap-fit ​​member to drive the movement of the housing assembly 100. The snap-fit ​​member 1127 can be a long slot or rail, and the other snap-fit ​​member can be a corresponding protrusion, etc., and the two cooperate to achieve the overall movement of the housing assembly 110. This facilitates adjusting the position of the housing assembly 110 on wearable devices such as glasses.

[0079] In some embodiments, the near-eye display device 30 may also include batteries, power supplies, control panels, sensors, communication units, camera modules, etc. The above units can work together in conjunction with the display module. This application will not describe the above connection and structural relationships in detail.

[0080] As shown in Figure 10, a wearable device is also proposed in this embodiment, including a frame 10 and the near-eye display device 30 mentioned above. The near-eye display device 30 is arranged on the frame 10. The frame 10 can be, for example, the main shell of a device such as ordinary glasses, smart glasses, and a helmet, such as the part that fixes the lens. Of course, the frame can also be the lens, or it can be the shell part directly used to be worn on the user's head. The frame 10 in this embodiment is a glasses frame. In other embodiments, the frame 10 can be a helmet, etc. Other components of the wearable device, such as communication units and other shell units, will not be described in detail in this application.

[0081] In some application scenarios, users of different ages and genders may have significantly different head circumferences and interpupillary distances, which presents challenges in device design and production. Existing technologies that use threads or lead screws to adjust interpupillary distances, while capable of meeting the needs of different users, are expensive and hinder design and development cost management.

[0082] The wearable device of the present application is described with reference to FIG. 11 to FIG. 19 .

[0083] An embodiment of the present application provides a wearable device, as shown in Figures 11 to 13, which includes a left frame 10, a right frame 20, a first nose bridge assembly 40, a cover plate 90, and a near-eye display device 30. The left frame 10 and the right frame 20 are both used to mount a lens 80, and the near-eye side 101 of the left frame 10 and / or the right frame 20 is provided with a receiving groove 540; the cover plate 90 covers the receiving groove 540 to form a receiving cavity, and the cover plate 90 has a light-transmitting portion. The near-eye display device 30 is installed in the receiving cavity. As shown in Figure 19, the near-eye display device 30 includes a display module 31 and an optical module 32 provided on one side of the display module 31. The light-emitting side of the optical module 32 faces the near-eye side 101 of the left frame 10 or the right frame 20 and is provided corresponding to the light-transmitting portion. The optical module 32 is configured to receive light from the display module 31 and project it to the human eye. As shown in Figure 13, the two ends of the first nose bridge component 40 are connected to the left frame 10 and the right frame 20 respectively. The first nose bridge component 40 is configured to releasably connect the left frame 10 and the right frame 20 to adjust the position of the near-eye display device 30 relative to the pupil of the human eye.

[0084] The wearable device can be ear-hook or head-mounted, for example, in the shape of a helmet, glasses, or other shapes. The near-eye side 101 of the left and right frames 10, 20 refers to the side of the left and right frames 10, 20 facing the human eye when the wearable device is worn. Conversely, the side of the left and right frames 10, 20 facing away from the human eye when the wearable device is worn is referred to as the ambient side 102 of the left and right frames 10, 20.

[0085] At least one of the left and right frames 10 and 20 is provided with a receiving slot 540. Specifically, the proximal side 101 of the left and / or right frames 10 and 20 is provided with the receiving slot 540. The cover plate 90 is assembled into the notch of the receiving slot 540 or installed within the left and / or right frames 10 and 20, and can block the notch of the receiving slot 540. The cover plate 90 can be sealed by snapping, screwing, or bonding. The proximal side 101 of the cover plate 90 can smoothly transition to the end surface of the proximal side 101 of the left and / or right frames 20. The end surface of the proximal side 101 of the left and / or right frames 20 can be the flattest plane or the lowest end surface of the left and / or right frames 10 and 20 facing the proximal side 101, such as the lowest end surface located near the nose pad.

[0086] The near-eye display device 30 is fixedly mounted in the receiving cavity of the cover plate 90, which blocks the notch of the receiving groove 540. Thus, the near-eye display device 30 is hidden inside the left frame 10 or the right frame 20. The near-eye display device 30 is located on the near-eye side 101, and the light it projects can directly enter the human eye. The cover plate 90 can also improve the installation aesthetics of the near-eye display device 30 and prevent external impurities from entering the interior and interfering with the normal operation of the near-eye display device 30.

[0087] Wherein, the near-eye display device 30 includes an optical module 32, a cover plate 90 having a light-transmitting portion, or the entire cover plate 90 is a transparent cover plate (a cover plate 90 made of a transparent material), and the optical module 32 is arranged corresponding to the light-transmitting portion. In the case where the cover plate 90 is a transparent cover plate 90, the embodiment of the present application does not specifically limit the position of the optical module 32. The optical module 32 faces the human eye, and its optical axis is tilted downward. The projection area of ​​the projection optical module 32 on the left frame 10 and / or the right frame 20 does not overlap with the lens 80, which can ensure that the optical module 32 is only located on the left frame 10 and / or the right frame 20, and does not affect the field of view of the lens 80. Wherein, the projection of the optical module 32 on the left frame 10 and / or the right frame 20 refers to the projection of the optical module 32 on the end face of the near-eye side 101 of the left frame 10 and / or the right frame 20.

[0088] It is understood that the end surface of the optical module 32 is slightly lower than the end surface (or surface) of the near-eye side 101 of the cover plate 90. The end surface of the near-eye side 101 of the cover plate 90 may include an arc-shaped protrusion or depression along the horizontal direction of the left frame 10 and / or the right frame 20. The arc-shaped protrusion or depression may be continuous or discontinuous. This may be for aesthetic design or to ensure high compatibility with the internal components of the display module 31.

[0089] The near-eye display device 30 also includes a display module 31 disposed on one side of the optical module 32. The display module 31 generates light to form an image source. The optical module 32 is mounted on the light-emitting side of the display module 31 via a bracket 35, receiving light from the display module 31 and projecting it into the human eye. The bracket 35 can provide support for the optical module 32 and protection for the display module 31. As shown in FIG19 , the display module 31 may include a microdisplay 311 and an adapter plate 312. The microdisplay 311 is located on the environmental side 102 of the optical module 32. One side of the adapter plate 312 is electrically connected to the microdisplay 311 via a first flexible circuit board 33, and the other side is connected to the electrical device via a second flexible circuit board 34.

[0090] In one embodiment, both ends of the first nose bridge assembly 40 are detachably connected to the left frame 10, such as by fasteners 42, or by snap-fitting. The first nose bridge assembly 40 can be configured with different lengths according to the pupil distance or head distance of different users, and the position of the near-eye display device relative to the human eye pupil can be adjusted, with low replacement cost.

[0091] The position of the near-eye display device 30 relative to the pupil of the human eye includes the relative position and orientation of the near-eye display device 30 and the pupil of the human eye, wherein orientation refers to the orientation or directional characteristics of an object, structure or system relative to a certain reference standard or direction. The orientation or directional characteristics may involve rotation, tilt, alignment, etc. of an object. In the embodiment of the present application, the orientation relationship between the near-eye display device and the pupil of the human eye can be determined by coordinates. Compared with the prior art that uses a screw or a slide to adjust the pupil distance or head distance, the embodiment of the present application can effectively reduce development costs and can adapt to the pupil distance and head distance of different users.

[0092] In another embodiment, both ends of the first nose bridge component 40 are connected to the left frame 10 and the right frame 20. The length of the first nose bridge component 40 is adjustable. The user does not need to disassemble the first nose bridge component 40. By adjusting the length of the first nose bridge component 40, the position and orientation of the near-eye display device 30 and the human eye pupil can be adjusted to adapt to the pupil distance and head distance of different users.

[0093] The wearable device provided in the embodiment of the present application configures the first nose bridge component 40 to be releasably connected to the left frame 10 and the right frame 20 respectively. Therefore, the first nose bridge component 40 can be configured with different lengths according to the user's pupil distance or head distance, or the length of the first nose bridge component 40 can be adjusted, thereby adapting to users with different pupil distances. The device is easy to disassemble and has low cost.

[0094] The left frame 10 and the right frame 20 of the embodiment of the present application are provided with a fixing hole 510 on one side close to the first nose bridge component 40. The fixing hole 510 is spaced apart from the near-eye display device 30. The fastener 42 passes through the fixing hole 510 to connect the two ends of the first nose bridge component 40 to the left frame 10 and the right frame 20 respectively.

[0095] Specifically, the first nose bridge assembly 40 includes a nose bridge housing 41, with mounting holes provided at both ends of the nose bridge housing 41. A fixing hole 510 is provided on the side of the left and right frames 10 and 20 near the nose bridge housing 41. The fixing holes 510 are spaced apart from the near-eye display device 30 to avoid interfering with the normal operation of the near-eye display device 30. Fasteners 42 are sequentially passed through the mounting holes and the fixing holes 510 to secure the ends of the nose bridge housing 41 to the left and right frames 10 and 20, respectively. The fasteners 42 can be bolts.

[0096] Alternatively, a clamping portion 520 is provided on one side of the left frame 10 and the right frame 20 close to the first nose bridge component 40 , and both ends of the first nose bridge component 40 are clamped in the clamping portion 520 .

[0097] In one embodiment, the left and right frames 10 and 20 are provided with engaging grooves on one side near the first nose bridge component 40, and the two sides of the first nose bridge component 40 are engaged with the corresponding engaging grooves. In another embodiment, the left and right frames 10 and 20 are provided with raised portions on one side near the first nose bridge component 40, and the two sides of the first nose bridge component 40 are provided with engaging grooves, and the two raised portions engage with the two engaging grooves in a one-to-one correspondence.

[0098] The first nose bridge assembly 40 provided in the embodiment of the present application is a telescopic structure with adjustable length. Specifically, the first nose bridge assembly 40 includes a first nose bridge segment and a second nose bridge segment. The length of the first nose bridge segment and the second nose bridge segment are adjustable. The user does not need to disassemble the first nose bridge assembly 40. By controlling the first nose bridge segment to slide along the extension direction of the second nose bridge segment, the length of the first nose bridge assembly can be adjusted to adapt to the pupil distance or head distance of different users, which is convenient to operate. It should be noted that the first nose bridge assembly 40 has a fixed structure to ensure that the first and second nose bridge segments remain stable after the length is adjusted, preventing accidental extension and retraction during use.

[0099] The first nose bridge assembly 40 provided in the embodiment of the present application includes a first nose bridge segment, a second nose bridge segment and a rotating member, and the first nose bridge segment is foldably connected to the second nose bridge segment through the rotating member.

[0100] In one embodiment, the rotating member includes a rotating shaft, and the first and second nose bridge segments are rotatably connected to the rotating member. The rotating shaft is perpendicular to the extension direction of the first and second nose bridge segments. The first nose bridge segment rotates toward or away from the second nose bridge segment relative to the rotating shaft to achieve folding and unfolding; alternatively, the second nose bridge segment rotates toward or away from the first nose bridge segment relative to the rotating shaft to achieve folding and unfolding. It will be appreciated that the rotating member includes a locking structure to ensure that the first and second nose bridge segments remain fixed when unfolded, preventing accidental folding during use.

[0101] In another embodiment, the rotating member is a flexible member, which can be made of an elastic material or a bendable metal material. The first nose bridge segment and the second nose bridge segment can be folded and unfolded by the flexible member. In addition, the flexible member can be adjusted according to the nose bridge shape and wearing habits of different users.

[0102] In the embodiment of the present application, the first nose bridge component 40 is a foldable structure. The first nose bridge component 40 can be folded along the length direction, as shown in Figure 18. This not only facilitates the storage of the first nose bridge component 40, but also helps to store wearable devices such as glasses. It should be noted that when the first nose bridge component 40 is a telescopic structure, it can also be folded. It is understandable that when the first nose bridge component 40 is folded, the user does not need to use it at this time and only needs to store it. Therefore, the first nose bridge component 40 can be folded in a retracted state or in an extended state without affecting subsequent use.

[0103] Based on any of the above embodiments, the wearable device provided in the embodiment of the present application also includes a second nose bridge component 50. As shown in Figures 15 to 17, the second nose bridge component 50 is spaced apart from the first nose bridge component 40, and the two ends of the second nose bridge component 50 are respectively detachably connected to the left frame 10 and the right frame 20, making the entire structure more stable.

[0104] In the embodiment of the present application, the two ends of the second nose bridge component 50 can be connected to the left frame 10 and the right frame 20 respectively via fasteners 42, or can be detachably connected by snapping. In the embodiment of the present application, the connection method between the two ends of the first nose bridge component 40 and the left frame 10 and the right frame 20 respectively can be the same as or different from the connection method between the two ends of the second nose bridge component 50 and the left frame 10 and the right frame 20 respectively.

[0105] It should be noted that if the first nose bridge assembly 40 is a retractable structure, the user can adjust the interpupillary distance or head distance by retracting the first nose bridge assembly 40. It is understood that the second nose bridge assembly 50 also needs to be retracted to achieve the corresponding adjustment, or the second nose bridge assembly 50 can be removed and replaced after the first nose bridge assembly 40 is adjusted to the target position. When the user folds the first nose bridge assembly 40 for storage, the second nose bridge assembly 50 is also a foldable structure, or the user can remove the second nose bridge assembly 50 and then fold it for storage.

[0106] Similarly, when the second nose bridge component 50 is a telescopic structure, it can also be folded. The nose pads in the embodiment of the present application can be installed on the second nose bridge component 50, or can be installed separately on the left frame 10 and the right frame 20. In the embodiment of the present application, the first nose bridge component 40 is longer than the second nose bridge component 50. The second nose bridge component 50 is arranged below the first nose bridge component 40 and can be arranged parallel to the first nose bridge component 40, which makes the appearance more coordinated and beautiful.

[0107] The wearable device provided in an embodiment of the present application further includes two temples 60 and a first flexible cable. The two temples 60 are respectively mounted on the left frame 10 and the right frame 20. The two temples 60 are rotatably mounted on the left frame 10 and the right frame 20 for convenient folding and storage. In another embodiment, the wearable device is shaped like a helmet or a headband, and the two temples 60 are fixedly connected to the left frame 10 and the right frame 20.

[0108] The first nose bridge assembly 40 is provided with a matching slot 44, and the first flexible cable is provided in the matching slot (44) for transmitting data information and / or power to the temple 60. For example, a battery and a circuit board are provided in the temple 60, and the first flexible cable is connected to the battery in the temple 60 to provide power supply; the first flexible cable is connected to the circuit board to provide signal support.

[0109] In one embodiment, the wearable device includes an electrical component 70 and a near-eye display device 30. The near-eye display device 30 is located on the near-eye side of the left frame 10 or the right frame 20. The electrical component is separately arranged in the two temples 60 to maintain the gravity balance of the two temples 60 and avoid the uneven weight distribution on the left and right sides when worn, which affects the wearing comfort. For example, the electrical component 70 includes at least a battery 71 and a circuit board 72, and the battery 71 and the circuit board 72 are separately arranged in the two temples 60. The battery 71 and the circuit board 72 are respectively connected to the near-eye display device 30. The battery 71 and the circuit board 72 are electrically connected via a first flexible cable, thereby achieving electrical connection between the electrical component 70, the first flexible cable, and the near-eye display device 30. It should be noted that the groove wall of the accommodating groove 540 is provided with a wire hole 530, and the connecting wire between the electrical component 70 and the adjacent near-eye display device 30 is passed through the wire hole 530.

[0110] In another embodiment, both the left and right frames 10 and 20 are equipped with a near-eye display device 30, and each temple 60 is equipped with an electrical component 70. As shown in FIG14 , the two temples 60 have the same weight, which improves wearing comfort. The temples 60 include temple bases 61 and temple covers 62. The temple bases 61 have mounting slots 611, and the electrical components 70 are mounted in the corresponding mounting slots 611. The temple covers 62 cover the mounting slots 611.

[0111] Specifically, a mounting slot 611 is provided on one end of the temple 60, near the frame, and the electrical component 70 is fixed within the mounting slot 611. Optionally, the open end of the mounting slot 611 faces the inner side of the temple 60, and the temple cover 62 covers the open end of the mounting slot 611, thereby hiding the installation gap of the temple cover 62 inside the temple 60, making the appearance of the entire wearable device more coordinated. The inner side of the temple 60 refers to the side of the temple 60 facing the human body when worn. The temple 60 is also provided with a key slot, and a control key 612 is embedded in the key slot. The control key is electrically connected to the near-eye display device 30, and the user can control the near-eye display device 30 through the control key 612. The groove wall of the accommodating groove 540 is provided with a wire hole 530. The connecting wire between the electrical component 70 and the adjacent near-eye display device 30 is passed through the wire hole 530 to provide power and signal support for the adjacent near-eye display device 30. The two near-eye display devices 30 are connected via a first flexible cable.

[0112] The connecting wire in the present application can be a structure such as a flexible circuit board or a communication cable that can realize the electrical connection between the display module 31 and the electrical device 70. In the case where the display module 31 includes a micro display 311 and an adapter board 312, the connecting wire is connected to the flexible circuit board on the right side of the adapter board 312. Furthermore, a first interactive component 43 is integrated on the first flexible cable, and the first interactive component 43 is electrically connected to the near-eye display device 30. The first interactive component 43 includes a capacitive sensor, and the user can interact with the near-eye display device 30 through the capacitive sensor. The two ends of the first interactive component 43 are respectively electrically connected to the near-eye display devices 30 on both sides; or, the two ends of the first interactive component 43 are respectively electrically connected to the electrical device 70 and the near-eye display device 30.

[0113] In one embodiment, a receiving slot 540 is provided in one of the left or right frames 10, 20, to which a near-eye display device 30 is mounted. One end of the first interactive component 43 is electrically connected to the electrical device 70 disposed within the temple 60, and the other end of the first interactive component 43 is electrically connected to the near-eye display device 30. The user can control the on / off and operation of the near-eye display device 30 via the first interactive component 43.

[0114] In another embodiment, both the left and right frames 10 and 20 are provided with receiving slots 540, each of which houses a near-eye display device 30. The first interactive component 43 has two ends connected to the two near-eye display devices 30, which are each electrically connected to the electrical device 70. The user can simultaneously control the switching and operation of the two near-eye display devices 30 through the first interactive component 43.

[0115] The wearable device provided in the embodiment of the present application includes a second nose bridge component 50, and the left frame 10 and the right frame 20 are both equipped with a near-eye display device 30. The wearable device also includes a second flexible cable, which is arranged in the second nose bridge component 50 and is used to transmit data information and / or power to the temple 60. For example, a battery and a circuit board are provided in the temple 60, and the second flexible cable is connected to the battery in the temple 60 to provide power supply; the second flexible cable is connected to the circuit board to provide signal support. It should be noted that a corresponding matching groove can also be provided on the second nose bridge component 50, and the second flexible cable is arranged in the matching groove. In the embodiment of the present application, the second flexible cable is integrated with a second interactive component, and the two near-eye display devices 30 are electrically connected to the first interactive component 43 and the second interactive component respectively.

[0116] Specifically, the near-eye side 101 of the left frame 10 is provided with a first receiving slot, which houses a first near-eye display device. The near-eye side 101 of the right frame 20 is provided with a second receiving slot, which houses a second near-eye display device. The first nose bridge assembly 40 is positioned above the second nose bridge assembly 50. The first interactive component 43 is integrated into the first flexible cable, and the second interactive component is integrated into the second flexible cable. Electrical components 70 are installed in both temples 60 to prevent interlacing of connecting wires.

[0117] The two ends of the first interactive component 43 are respectively connected to the first near-eye display device and the electrical device 70 in the adjacent temple 60, and the two ends of the second interactive component are respectively connected to the second near-eye display device and the electrical device 70 in the adjacent temple 60; the user can control the switching and operation of the first near-eye display device 30 through the first interactive component 43, and control the switching and operation of the second near-eye display device 30 through the second interactive component. The embodiment of the present application controls the two near-eye display devices 30 through two paths to achieve separate control and reduce interference. It should be noted that when the first nose bridge component 40 is a telescopic structure or a foldable structure, the extension or folding of the first nose bridge component 40 does not interfere with the first interactive component 43, nor does it affect the arrangement of the corresponding connecting wires.

[0118] Similarly, the second nose bridge component 50 is a telescopic structure or a foldable structure. The extension or folding of the second nose bridge component 50 does not interfere with the second interactive component, nor does it affect the arrangement of the corresponding connecting wires. The first interactive component 43 and the second interactive component in the embodiment of the present application both include at least one of a capacitive sensor, an inertial unit, an accelerometer, a gyroscope, and a camera. The user can control the first interactive component 43 and / or the second interactive component by single-clicking, double-clicking, gestures, sliding, etc. to achieve interaction, adjust the brightness of the display module 31, pause or play the content displayed by the display module 31, adjust the volume, and other operations. The wearable device provided in the embodiment of the present application also includes a third interactive component, which is installed on the temple 60 and is electrically connected to the electrical device 70. The third interactive component has a different interactive function from the first interactive component. The third interactive component includes sensors for environmental monitoring and human biological sign monitoring, and capacitive sensors. When the third interactive component is used for human biological sign detection, the third interactive sensor is connected to the battery in the electrical device 70. When the third interactive component is used to control the near-eye display device 30, for example, the circuit board is provided with a power button, a control button, etc. to control the switching and operation of the near-eye display device 30. At this time, the third interactive component is connected to the circuit board 72 in the electrical device 70.

[0119] In some application scenarios, display solutions using technologies such as optical waveguides are often large in size and volume. In other technical solutions, the near-eye display device is too protruding after installation and fixation, which can easily cause physiological discomfort to the user and interfere with the user's vision, resulting in a poor user experience. The wearable device of the present application is described below in conjunction with Figures 20 to 27. The embodiment of the present application provides a wearable device, as shown in Figures 20 to 23, which includes a frame 10, a cover plate 90 and a near-eye display device 30. As shown in Figure 23, the frame 10 is used to mount the lens 80. A receiving groove 11 is provided on the frame 10. The cover plate 90 covers the receiving groove 11 to form a receiving cavity, and the near-eye display device 30 is installed in the receiving cavity. A light-transmitting hole 91 is provided on the near-eye side 101 of the receiving cavity. As shown in Figure 21, the near-eye display device 30 includes a display module 31 and an optical module 32 provided on one side of the display module 31. The optical module 32 can be located on the light-emitting side of the display module 31. As shown in FIG20 , the light-emitting side of the optical module 32 faces the near-eye side 101 of the frame 10 and is provided corresponding to the light-transmitting hole 91. The shape of the light-transmitting hole 91 can be adapted to the shape of the outer contour of the optical module 32, for example, the two are similar. In other embodiments, the shape of the light-transmitting hole 91 can be longer than the optical module 32. In some embodiments, the end face of the optical module 32 exceeds the near-eye side end face of the frame 10 by no more than 5 mm, for example, 1 mm, 2 mm, etc., or the two are flush with each other, wherein the end face of the optical module 32 can be the end face from which the light is finally emitted, and the near-eye side end face of the frame 10 can be the flattest plane or the lowest end face of the frame 10 facing the near-eye side, for example, the lowest end face located near the nose pad.

[0120] The wearable device can be ear-hanging or head-mounted, for example, the whole can be in the shape of a helmet, glasses or other shapes. For example, the frame 10 is only equipped with one lens 80, and when worn, the lens 80 spans the left eye and the right eye of the user. Of course, the frame 10 can also be equipped with only one lens 80, and the lens 80 only corresponds to the left eye or the right eye of the user, and is used as a monocular. For another example, two lenses 80 are installed on the frame 10, and the two lenses 80 correspond one-to-one to the left eye and the right eye of the user. Among them, the near-eye side 101 of the frame 10 refers to the side of the frame 10 facing the human eye when the wearable device is in the wearing state. Conversely, when the wearable device is in the wearing state, the side of the frame 10 facing away from the human eye is the environmental side 102 of the frame 10.

[0121] The upper part of the frame 10 is provided with a receiving groove 11, and the cover plate 90 is assembled in the notch of the receiving groove 11 or installed in the frame 10, as long as the notch of the receiving groove 11 can be blocked. The near-eye display device 30 is fixedly installed in the receiving cavity formed after the cover plate 90 blocks the notch of the receiving groove 11. As a result, the near-eye display device 30 is hidden inside the frame 10, and the near-eye display device 30 is located on the near-eye side 101. The light it projects can directly enter the human eye, making it difficult for the near-eye display device 30 as a whole to protrude too much from the frame 10, for example, 5 mm or more above the surface of the near-eye side 101 of the frame 10, etc., so that the cover plate 90 can be used to improve the installation aesthetics of the near-eye display device 30, and can also prevent external impurities from entering the interior and interfering with the normal operation of the near-eye display device 30.

[0122] As shown in Figure 21, the near-eye display device 30 includes a display module 31 and an optical module 32. The display module 31 generates light to form an image source. The optical module 32 is mounted on the light-emitting side of the display module 31 via a bracket 35. It receives light from the display module 31 and projects it into the human eye. The bracket 35 provides support for the optical module 32 and protection for the display module 31.

[0123] The wearable device provided in the embodiment of the present application is provided with a receiving groove 11 on the frame 10, and the sealing groove is sealed with a cover plate 90 to form a receiving cavity, so that the near-eye display device 30 is located inside the frame 10, thereby preventing the near-eye display device 30 from protruding from the frame 10 and interfering with the user's vision.

[0124] In one embodiment, the notch of the receiving groove 11 faces the ambient side 102 of the frame 10, and the light-transmitting hole 91 is located at the bottom of the receiving groove 11. That is, the light-transmitting hole 91 can be provided on the main body of the frame 10, and the cover plate 90 covers the notch on the ambient side 102 to form a receiving cavity. In another embodiment, as shown in FIG23 , the notch of the receiving groove 11 faces the near-eye side of the frame 10, and the light-transmitting hole 91 is provided on the cover plate 90. The notch of the receiving groove 11 facing the near-eye side 101 of the frame 10 can conceal the connection traces formed by the cover plate 90 covering the receiving groove 11, thereby improving the overall coordination of the wearable device's appearance.

[0125] The optical module 32 faces the eye, with its optical axis tilted downward. The projection area of ​​the optical module 32 on the frame 10 does not overlap with the lens 80, ensuring that the optical module 32 is located only on the frame 10 and does not affect the field of view of the lens 80. The projection of the optical module 32 on the frame 10 refers to the projection of the optical module 32 on the end face of the frame 10 near the eye 101.

[0126] To reduce the shaking of the optical module 32 in the accommodating cavity, the optical module 32 is at least partially inserted into the light-transmitting hole 91 , and the optical module 32 is positioned with the help of the light-transmitting hole 91 , while also reducing the thickness of the frame 10 at the optical module 32 .

[0127] It is understandable that, when the near-eye side 101 of the cover plate 90 is flush with the near-eye side 101 of the frame 10, the end face of the optical module 32 can be flush with the near-eye side end face (or surface) of the cover plate 90 or slightly lower than the near-eye side end face (or surface) of the cover plate 90. In some embodiments, the end face of the near-eye side 101 of the cover plate 90 can include an arc-shaped protrusion or depression along the transverse direction of the frame 10, which can be a continuous or discontinuous arc-shaped protrusion or depression. It can be used as an aesthetic design, or it can be used to show the compatibility and adaptation of the internal components of the module 31. When the end face (surface) of the near-eye side 101 of the cover plate 90 is lower than the end face of the near-eye side 101 of the frame 10, for example, when the cover plate 90 forms a depression on the surface of the frame 10, the end face of the optical module 32 can be flush with the near-eye side 101 of the cover plate 90 or higher or lower than the near-eye side 101 of the cover plate 90.

[0128] 23-24 , the light hole 91 extends along the length of the lens frame 10 and is longer than the optical module 32 , that is, the light hole 91 is in an elongated strip shape.

[0129] The optical module 32 has an optical axis, and the human eye has a visual axis. Under normal circumstances, the visual axis of the human eye is related to factors such as the human pupil distance. Therefore, the positions of the visual axes of different people are different. When the optical axis of the optical module 32 is aligned with the visual axis of the human eye, the human eye can better receive the light projected by the optical module 32, forming a better display effect. Compared with the way the near-eye display device 30 is fixed in the accommodating cavity, the elongated light-transmitting hole 91 allows the optical module 32 to be slidably installed in the frame 10, and the position of the optical module 32 can be adjusted according to the pupil distance of different users. Since the optical module 32 can move in the elongated light-transmitting hole 91, the position of the optical module 32 relative to the frame 10 is adjusted accordingly, so that the optical axis of the optical module 32 moves accordingly, thereby adapting to the user's eye pupil distance. For more descriptions of the optical module, please refer to the description of the above-mentioned related embodiments.

[0130] It is understood that the optical module 32 and the sidewalls of the elongated light-transmitting hole 91 are in a tight fit, and the optical module 32 can only move under the action of an external force. After moving into position, the external force is removed, and the position of the optical module 32 relative to the elongated light-transmitting hole 91 will no longer move. In some embodiments, as shown in Figure 24, a sub-cover 107 can also be provided corresponding to the elongated light-transmitting hole 91. The sub-cover 107 slides within the frame 10 as the optical module 32 moves. The sub-cover 107 can shield the components inside the receiving slot 11 to prevent foreign matter from entering.

[0131] In some embodiments, the cover plate 90 can also be slidably installed inside the frame 10 or can be slidably embedded in the frame 10. During the movement, the cover plate 90 can ensure that the receiving groove 11 is always in a sealed state to prevent the near-eye display device 30 installed inside from being exposed.

[0132] As shown in FIG. 20 , the end surface of the near-eye side 101 of the cover plate 90 and the end surface of the near-eye side 101 of the lens frame 10 can be smoothly transitioned.

[0133] In one embodiment, the cover plate 90 can be attached to the receiving slot 11 by bonding or snapping. As shown in Figure 3, the circumferential side surfaces of the cover plate 90 fit against the walls of the receiving slot 11, providing a secure and positioning mechanism. In another embodiment, the cover plate 90 is fixed to the frame 10 using screws or other fastening structures. This is sufficient as long as the proximal end surface 101 of the cover plate 90 does not protrude excessively from the proximal end surface 101 of the frame 10, for example, providing a smooth transition.

[0134] In one embodiment, as shown in Figure 21 , the display module 31 may include a microdisplay 311 and an adapter plate 312. The microdisplay 311 is located on the ambient side 102 of the optical module 32. One side of the adapter plate 312 is electrically connected to the microdisplay 311 via the first flexible printed circuit board 33, and the other side is connected to the electrical device 70 via the second flexible printed circuit board 34. As shown in Figure 25 , the cover plate 90 has a first abutting section 92 and a second abutting section 93 of different heights. The first flexible printed circuit board 33 is bonded to the first abutting section 92, and the second flexible printed circuit board 34 is bonded to the second abutting section 93. The abutting sections provide support for the flexible printed circuit boards, enhancing their strength. The adapter plate 312 is located between the first abutting section 92 and the second abutting section 93. It is understood that the middle position between the first abutting section 92 and the second abutting section 93 can be a groove with a lower height than the first abutting section 92 and the second abutting section 93. The adapter plate 312 is located in the groove, and the side walls of the adapter plate 312 can adapt to the side walls of the groove, thereby more firmly fixing the adapter plate 312 and reducing the chance of the entire display module 31 shaking when assembled in the receiving groove 11. For the relevant description of the micro display 311, please refer to the above-mentioned relevant embodiments.

[0135] As shown in Figure 21, the micro display 311 and the adapter plate 312 are arranged in a straight line, and the two are connected by a first flexible circuit board 33. That is, the micro display 311 and the adapter plate 312 are arranged along the lateral spacing of the frame 10, so as to make full use of the lateral space of the frame 10, avoid the display module 31 being too thick, which leads to an increase in the thickness of the frame 10, reduce the visual intrusion of the near-eye display device 30 to the human eye, and thus help improve the comfort of the wearable device. It can be understood that in order to ensure that the optical module 32 can move along with the cover plate 90 during the sliding process, the first flexible circuit board 33 has a certain amount of redundancy or a certain degree of elasticity to ensure that when the optical module 32 moves, the micro display 311 and the adapter plate 312 are always in a connected state.

[0136] In order to improve the assembly stability of the cover 90 and the frame 10, a first supporting structure is protruded in the accommodating groove 11, and the first supporting structure is against the inner side surface of the cover 90; and / or, the cover 90 has a second supporting structure, and the second supporting structure is against the wall of the accommodating groove 11.

[0137] The first and second support structures can be ribs or raised blocks. For example, the first support structure can be protruding from the bottom of the receiving groove 11, and the first support structure can abut against the inner side of the cover plate 90 to prevent the cover plate 90 from shaking within the receiving groove 11. Alternatively, a second support structure can be constructed on the inner side of the cover plate 90, and the second support structure can abut against the bottom of the receiving groove 11. Alternatively, the first support structure can be protruding from the receiving groove 11, and the cover plate 90 can be provided with a second support structure.

[0138] The notch of the receiving groove 11 faces the near-eye side 101 of the frame 10. Optionally, a third supporting structure is provided at the bottom of the receiving groove 11. The third supporting structure is abutted against the display module 31 to prevent the display module 31 from shaking in the receiving groove 11 due to excessive installation clearance. The third supporting structure can be a support bar or a support block, which provides support from the bottom of the display module 31 and cooperates with the cover plate 90 to fix the display module 31. Specifically, some of the third supporting structures are abutted against the side of the micro display 311 away from the near-eye side 101 of the frame 10, and other third supporting structures are abutted against the adapter plate 312. Alternatively, the third supporting structure is only abutted against the micro display 311 or the adapter plate 312.

[0139] As shown in Figure 26, the frame 10 includes a crossbeam 12 and a lens frame 13, and the crossbeam 12 and the lens frame 13 are detachably connected. For example, the crossbeam 12 is magnetically or snap-connected to the lens 80. The lens 80 is mounted on the lens frame 13, and the receiving groove 11 is provided on the crossbeam 12. The crossbeam 12 and the lens frame 13 are correspondingly provided with fixing holes 15, and the fixing parts are passed through the relatively arranged fixing holes 15 to connect the crossbeam 12 and the lens frame 13. Among them, the lens 80 can be a goggle lens, a touch screen lens, a myopia lens, a hyperopia lens, a sun protection lens, etc. The crossbeam 12 is used to install the near-eye display device 30, and there is no need to install the lens 80, so that the thickness of the crossbeam 12 is not affected by other components.

[0140] The thickness of the crossbeam 12 is greater than that of the lens frame 13. When the near-eye display device 30 is not in use, the lens frame 13 can be removed from the crossbeam 12 and used as ordinary glasses, reducing the weight of the glasses. When the near-eye display device 30 is needed, the lens frame 13 is connected to the crossbeam 12. In addition, the detachable connection between the crossbeam 12 and the lens frame 13 facilitates the combination of the near-eye display device 30 with different types of lens frames 13, enriching usage scenarios. It also allows for easy disassembly and repair if only the lens 80 or the near-eye display device 30 is damaged.

[0141] 26 , the crossbeam 12 is provided with an adapting groove 14, and the lens frame 13 is provided with a clamping block 16, which is plugged into the adapting groove 14. There are multiple adapting grooves 14, which are spaced apart along the length of the crossbeam 12.

[0142] As shown in Figure 26, fitting grooves 14 are provided in the middle and at opposite ends of the crossbeam 12. Correspondingly, retaining blocks 16 are provided in the nose bridge area and on opposite sides of the lens frame 13. These retaining blocks 16 fit within the fitting grooves 14, ensuring a tight fit between the bottom wall of the crossbeam 12 and the top wall of the lens frame 13, preventing excessive installation gaps. The stepped surfaces formed by retaining blocks 16 provide positioning during installation, preventing deformation of the lens frame 13 and crossbeam 12 due to improper operation.

[0143] Fixing holes 15 are correspondingly provided on the groove wall and the block 16 of the adapter groove 14. After the block 16 is clamped in the adapter groove 14, fasteners such as screws or bolts pass through the fixing holes 15 to fix the crossbeam 12 and the lens frame 13. As shown in Figure 26, fixing holes 15 are provided at both ends of the adapter groove 14 located in the middle of the crossbeam 12. With the help of two screws, the lens frame 13 can be fastened to the crossbeam 12 so that the force on the left and right sides of the lens frame 13 is balanced. In order to effectively avoid the screws from being exposed, the fixing holes 15 are provided on the groove wall of the near-eye side 101 of the adapter groove 14. In order to reduce the installation gap between the bottom of the crossbeam 12 and the top of the lens frame 13, fixing holes 15 are also provided on the groove wall of the adapter groove 14 on the left and / or right side of the crossbeam 12. Among them, the length of the adaptation groove 14 located in the middle position of the beam 12 is greater than the length of the adaptation groove 14 located at the two side ends of the beam 12. It can be understood that taking the left and right directions in Figure 26 as an example of the length direction of the beam 12, the adaptation groove 14 in the middle position of the beam 12 is greater than the length of the adaptation groove 14 on the left and right sides. The middle position corresponds to the position of the nose pad or roughly the position of the nose pad (that is, the middle position of the two eyes), which can effectively reduce the space at both ends and make full use of the position of the middle beam 12, so that the fixation of the beam 12 and the lens frame 13 is more stable.

[0144] In one embodiment, the wearable device includes temples 60, which are mounted on the frame 10. As shown in FIG27 , an electrical component 70 is disposed within the temples 60. The electrical component 70 includes a battery 71 and / or a circuit board 72. For example, the circuit board 72 may include a power button, control buttons, etc. to control the power on and off of the near-eye display device 30. The electrical component 70 is connected to the display module 31. As shown in FIG22 , the wall of the receiving slot 11 is provided with a wire hole 17, through which the connecting wires between the display module 31 and the electrical component 70 are passed.

[0145] It is understood that the temples 60 can be rotatably mounted on the frame 10 or fixed to the frame 10. For example, the temples 60 can be rotatably mounted on the crossbar 12 for easy folding and storage. In another example, the wearable device is in the shape of a helmet or headband, and the temples 60 are fixedly connected to the frame 10.

[0146] Among them, each temple 60 is equipped with an electrical component 70 to balance the weight of the temples 60 on both sides, avoiding inconsistent weight distribution on the left and right sides when worn, which affects the wearing comfort. It should be noted that the electrical components 70 in the two temples 60 can be exactly the same, or the electrical components 70 can be dispersed in the two temples 60 to balance the weight of the two temples 60. Specifically, the temple 60 is provided with a mounting cavity or mounting groove 611 at one end close to the frame 10, and the electrical component 70 is fixed in the mounting cavity 611. Optionally, the open end of the mounting cavity (mounting groove) 611 faces the inner side of the temple 60, and the cover body or temple cover 62 covers the open end of the mounting cavity 611, thereby hiding the installation gap of the cover body 62 on the inner side of the temple 60, making the appearance of the entire wearable device more coordinated. The inner side of the temple 60 refers to the side of the temple 60 facing the human body when worn.

[0147] The connecting wire can be a flexible circuit board or a communication cable, etc., which can realize the electrical connection between the display module 31 and the electrical device 70. In the case where the display module 31 includes a micro display 311 and an adapter board 312, the connecting wire is connected to the flexible circuit board on the right side of the adapter board 312.

[0148] In a specific embodiment, as shown in Figure 27, connecting parts 18 are respectively protruded from the opposite ends of the frame 10, and the two temples 60 are rotatably connected to the connecting parts 18 in a one-to-one correspondence. The connecting part 18 is provided with a channel connected to the wire hole 17, and the channel is connected to the installation cavity 611.

[0149] As shown in Figure 27, the connecting portion 18 is located on the near-eye side 101 of the frame 10. The connecting portion 18 has a rotating shaft and a limiting end surface, with the rotating shaft protruding from the limiting end surface. The opposite sidewalls of the mounting cavity 611 are provided with an adapter hole, into which the rotating shaft is inserted. Alternatively, a connecting shaft is provided through the adapter hole and the connecting portion 18 to achieve a rotational connection between the connecting portion 18 and the temple 60. When the temple 60 is rotated relative to the connecting portion 18 to the extended position, the end of the temple 60 abuts against the limiting end surface.

[0150] In one embodiment, only one near-eye display device 30 is provided on the frame 10, and the near-eye display device 30 is provided corresponding to the user's left eye or right eye. In another embodiment, as shown in Figures 20 and 23, the frame 10 includes a left eye frame and a right eye frame, each of which is provided with a receiving slot 11. The near-eye display device 30 corresponds to the receiving slot 11 one-to-one, thereby balancing the weight on the left and right sides of the frame 10 and improving wearing comfort.

[0151] The near-eye display module can be installed on near-eye display devices such as glasses and helmets for users to use. Due to factors such as the position of the eyes, the visual axes of different people are different. When the light emitted by the near-eye display module is aligned with the visual axis of the human eye, the human eye can better receive the light emitted by the near-eye display module and form a better display effect. For this reason, manufacturers need to manufacture multiple different models of the same near-eye display device. Among them, the difference between different models of equipment is that the installation position of the near-eye display module is different, thereby satisfying users with different visual axis positions. This brings about the problem of high production and manufacturing costs.

[0152] Referring to Figures 28-38, in this embodiment, a near-eye display device is proposed, including a frame 10, a first sliding portion 2201, a near-eye display module 300, and a second sliding portion 320. In this embodiment, the frame 10 is described using glasses as an example. In other embodiments, the frame 10 can also be a helmet, etc. The frame 10 is provided with a cavity 103 and a light-transmitting window 104 connected to the cavity 103, with the light-transmitting window 104 facing the eye side 101 of the frame 10. When the frame 10 is worn on the user's head, the light-transmitting window 104 faces the eye side of the frame 10, and the light-transmitting window 104 faces away from the ambient side 102 of the frame 10. In addition, the frame 10 has a first direction X and a second direction Y, which are perpendicular to each other. The first sliding portion 2201 is located at a position on the housing 100 corresponding to the light-transmitting window 104. The near-eye display module 300 is disposed within the cavity or accommodating groove 103. At least a portion of the near-eye display module 300 is exposed relative to the light-transmitting window 104 and is configured to allow light to be emitted through the light-transmitting window 104. When a user wears the frame 10, light emitted by the near-eye display module 300 is irradiated into the user's eyes through the light-transmitting window 104, allowing the user to view the image source displayed by the near-eye display module 300. A second sliding portion 320 is disposed on the periphery of the near-eye display module 300; the first sliding portion 2201 and the second sliding portion 320 are configured to allow the near-eye display module 300 to move within the cavity 103.

[0153] In the embodiment of the present application, since the near-eye display module 300 is arranged in the cavity (or accommodating groove) 103 of the frame 10, and is configured to allow the near-eye display module 300 to move in the cavity 103 through the first sliding portion 2201 and the second sliding portion 320, the near-eye display module 300 can be adjusted to different positions in the cavity 103 according to the pupil distance of different users, thereby adapting to the pupil distance of different users. There is no need to produce different shells for the pupil distance of different users, thereby reducing manufacturing costs.

[0154] In some embodiments, as shown in Figures 29 and 30, the near-eye display module 300 includes a microdisplay 210, an optical module 220, and a fixing base 230. The microdisplay 210 and the optical module 220 are located within the fixing base 230. The light-transmitting window 104 extends along the first direction X of the frame 10. The length of the light-transmitting window 104 is greater than the length of the fixing base 230. The second sliding portion 320 is disposed on the fixing base 230. The first sliding portion 2201 extends along the first direction X. The microdisplay 210, the optical module 220, and the fixing base 230 are configured to allow movement within the cavity 103 along the first direction X. The microdisplay 210 is used to project light and can provide an image source, such as text, video, information prompts, etc. For a description of the microdisplay 210, reference can be made to the above-mentioned related embodiments. The optical module 220 is spaced apart from the microdisplay 210, wherein the optical module 220 can be made of transparent or light-transmitting materials, such as PMMA polymethyl methacrylate, polymethyl methacrylate, PC polycarbonate, polycarbonate plastic, resin, glass, etc. The optical module 220 as a whole can be cylindrical, such as cylindrical, prism-shaped, or truncated cone-shaped, etc., and of course, it can also be an irregular shape, etc. For more descriptions of the optical module, please refer to the descriptions of the above-mentioned related embodiments. The fixing seat 230 realizes the connection between the optical module 220 and the microdisplay 210, so that when the fixing seat 230 moves in the cavity 103, it drives the optical module 220 and the microdisplay 210 to move in the cavity 103, and the fixing seat 230, the optical module 220, and the microdisplay 210 are relatively stationary.

[0155] Because the length of the light-transmitting window 104 is greater than that of the fixing base 230, and the second sliding portion 320 is disposed on the fixing base 230, the fixing base 230 can drive the microdisplay 210 and the optical module 220 to move within the cavity 103 along the first direction X to achieve a position that accommodates the user's interpupillary distance. When the user wears the frame 10, light emitted by the microdisplay 210 passes through the optical module 220 and the light-transmitting window 104 and enters the user's eyes, allowing the user to view the image source displayed by the microdisplay 210.

[0156] In some embodiments, as shown in Figures 29 and 31, the near-eye display device further includes a bracket 301, which is disposed on the light-transmitting window 104. The bracket 301 is provided with a mounting through hole 310 along the first direction X, wherein the first sliding portion 2201 is disposed on the bracket 301.

[0157] Because the first sliding portion 2201 is located on the bracket 301, which is mounted on the light-transmitting window 104, and the second sliding portion 320 is mounted on the fixing base 230 of the near-eye display module 300, the first sliding portion 2201 and the second sliding portion 320 are slidably connected. The interaction between the first sliding portion 2201 and the second sliding portion 320 ensures the stability of the near-eye display module 300 when it slides relative to the mounting hole 310.

[0158] The mounting hole 310 can be a waist-shaped hole, a square hole, a rectangular hole, or any other shape. Any simple variation or transformation of the shape of the hole that allows the near-eye display module 300 to slide relative to the mounting hole 310 falls within the scope of protection of this application. The sliding direction of the optical module 220 relative to the mounting hole 310 is parallel to the first direction X. When the user wears the frame 10, the first direction X of the frame 10 is approximately parallel to the line connecting the centers of the user's two eyes.

[0159] In some embodiments, as shown in Figures 30-33, the first sliding portion 2201 and the second sliding portion 320 each include two strips, and the two second sliding portions 320 are respectively arranged on opposite sides of the bracket 301 along the second direction Y; the two first sliding portions 2201 are respectively arranged on opposite sides of the fixing seat 230 along the second direction Y, and the second sliding portions 320 are not located in the mounting through hole 310.

[0160] After the near-eye display module 300 and the bracket 301 are assembled, because the second sliding portion 320 is not located within the mounting through-hole 310, the near-eye display module 300 does not extend from the mounting through-hole 310 toward the eye side, but is instead spaced apart from the plane of the mounting through-hole 310 along the first direction X. It will be appreciated that the number of first sliding portions 2201 and second sliding portions 320 is not limited to two, and any other number is acceptable, as long as the first sliding portion 2201 can be tightly fitted with the second sliding portion 320.

[0161] In some embodiments, the length of the mounting hole 310 can be 6 mm to 12 mm. In some embodiments, the maximum dimension of the optical module 220 is less than or equal to 20 mm, such as 20 mm, 18 mm, 15 mm, etc., to facilitate fitting the optical module 220 into a smaller space. The length of the mounting hole 310 refers to the length between the two top ends along the first direction X.

[0162] Therefore, the range of movement of the near-eye display module 300 in the first direction X within the mounting hole 310, as shown in FIG34 and FIG35 , from the first position to the second position, the movement distance of the optical module 220 is 0 mm to 12 mm, that is, the maximum distance that the optical module 220 can move within the mounting hole 310 can be 0 mm to 12 mm. For example, in some embodiments, the maximum distance that the near-eye display module 300 can move within the mounting hole 310 is 0 mm, 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, or 12 mm, etc.

[0163] The first position and the second position are merely two extreme positions of the optical module 220 relative to the mounting hole 310, that is, the near-eye display module 300 can be adjusted within the mounting hole 310 along the first direction X in a range of 0mm-12mm, wherein the optical module 220 can be moved to any position between the first position and the second position.

[0164] The near-eye display module 300 has an optical axis, and the human eye has a visual axis. Generally, the visual axis of the human eye is related to factors such as the distance between the pupils of the human eye. Therefore, the visual axis positions of different people are different. When the optical axis of the optical module 220 in the near-eye display module 300 is aligned with the visual axis of the human eye, the human eye can better receive the light projected by the near-eye display module 300, forming a better display effect. When the user wears the frame 10, the frame 10 and the user's head can be regarded as being in a relatively fixed state. Since the optical module 220 in the near-eye display module 300 is fixedly connected to the micro display 210, and the optical module 220 can be slidably arranged in the mounting through hole 310, by adjusting the position of the near-eye display module 300, the position of the near-eye display module 300 relative to the frame 10 is changed, thereby realizing the movement of the optical axis of the optical module 220 to adapt to the visual axis position of different users and adapt to the distance between the pupils of different users.

[0165] In some embodiments, as shown in Figures 31-33, one of the first sliding portion 2201 and the second sliding portion 320 is a slider and the other is a slot; the slider is slidably disposed in the slot, and the slider and the slot are tightly fitted. Since there are two first sliding portions 2201 and two second sliding portions 320, the connection between the fixing base 230 of the near-eye display module 300 and the bracket 301 is more reliable when they are assembled. When the fixing base 230 drives the micro display 210 and the optical module 220 to adjust their positions relative to the bracket 301, the sliding process is smoother.

[0166] The first sliding connection 2201 and the second sliding connection 320 are each formed as a slider and a slot. The slider is slidably disposed within the slot, and the slider and slot are tightly fitted. Because the slider and slot are tightly fitted, the optical module 220 can only slide relative to the bracket 301 when subjected to sufficient external force. This ensures the stability of the relative position of the near-eye display module 300 and the bracket 301, preventing the near-eye display module 300 from shifting within the mounting hole 310 due to collisions or shaking of the frame 10.

[0167] In this embodiment, the first sliding connection 2201 is a slider, and the second sliding connection 320 is a slot. In other embodiments, the first sliding connection 2201 is a slot, and the second sliding connection 320 is a slider. It is understood that the first sliding connection 2201 and the second sliding connection 320 are not limited to sliders and slots, and can also be screw rod structures or gear meshing structures, which are not limited here.

[0168] In some embodiments, in this embodiment, the bracket 301 is provided with a first connecting portion 330. In other embodiments, as shown in FIG36-FIG37 , the frame 10 is provided with a second connecting portion 120, wherein the first connecting portion 330 is connected to the second connecting portion 120. Thus, the connection between the bracket 301 and the frame 10 is achieved.

[0169] The bracket 301 is provided with a first connecting portion 330 at both ends in the second direction Y, wherein the second connecting portion 120 corresponds one-to-one with the first connecting portion 330. Since there are two first connecting portions 330 and two second connecting portions 120, when the bracket 301 and the frame 10 are assembled, the reliability and stability of the connection between the two can be ensured to be higher.

[0170] One of the first connecting portion 330 and the second connecting portion 120 is a plug-in protrusion, and the other is a slot. The plug-in protrusion plugs into the slot. In some embodiments, the first connecting portion 330 is a plug-in protrusion and the second connecting portion 120 is a slot. In other embodiments, the first connecting portion 330 is a slot and the second connecting portion 120 is a plug-in protrusion.

[0171] It can be understood that the connection between the first connecting part 330 and the second connecting part 120 is not limited to the method of plug-in protrusions and slots, but can also be a connection method such as screw connection, magnetic attraction, bonding or snap connection. As long as the connection method can ensure the reliability and stability when the bracket 301 is assembled with the frame 10, it is a simple deformation and transformation of the present application and falls within the scope of protection of the present application.

[0172] In some embodiments, as shown in FIG32 , an inner recess 3102 is further provided on the mounting hole 310 , and the recessed direction of the inner recess 3102 is away from the center of the mounting hole 310 , and the inner recess 3102 includes two inner recesses 3102 that are arranged opposite to each other in the second direction Y.

[0173] Specifically, by providing the recessed portion 3102, the position of the near-eye display module 300 within the mounting hole 310 can be easily adjusted. In other embodiments, if the mounting hole 310 is sufficiently large, the recessed portion 3102 is not required. In some embodiments, as shown in FIG32 , the inner wall of the mounting hole 310 is provided with a first step 3101, which protrudes toward the center of the mounting hole 310, and the recessed portion 3102 is located on the first step 3101.

[0174] In some embodiments, as shown in Figures 28 and 29, the near-eye display device also includes a cover plate 340, and the bracket 301 is provided with a second step 350 away from the second sliding portion 320, and the second step 350 is higher than the first step 3101. The cover plate 340 is covered on the second step 350, for example, by bonding, clamping or fasteners; the end face of the optical module 220 is less than or equal to the end face of the second step 350, and the optical module 220 is spaced apart from the cover plate 340.

[0175] The end face of the optical module 220 is smaller than or equal to the end face of the second step 350, so that the optical module 220 can correspond to the light-transmitting window 104, so that the light of the near-eye display module 300 can be emitted through the mounting hole 310 and the light-transmitting window 104 in sequence. The first step 3101 is used to form the inner recess 3102, and the second step 350 prevents the optical module 220 from contacting the cover plate 340. In some embodiments, as shown in Figure 33, the plane A where the two second sliding parts 320 are located is not parallel to the plane B where the mounting hole 310 is located, and the optical axis of the optical module 220 is not perpendicular to the plane B where the mounting hole 310 is located. That is, the extension line of the plane A where the two second sliding parts 320 are located and the extension line of the plane B where the mounting hole 310 is located will form an angle, and the optical axis of the optical module 220 will not be perpendicular to the plane B where the mounting hole 310 is located.

[0176] Since the optical axis of the optical module 220 is not perpendicular to the plane B where the mounting hole 310 is located, the optical module 220 is tilted toward the side of the glasses. This arrangement allows the light emitted by the microdisplay 210 to pass through the optical module 220 and enter the user's eyes. The user can comfortably watch the image source played by the microdisplay 210 without excessively rotating the eyeballs.

[0177] In some embodiments, as shown in Figures 28 to 38, a groove 140 with the cavity 103 is provided on the side of the frame 10 facing away from the bracket 301, and the near-eye display device also includes a cover shell 150 and temples 60, and the cover shell 150 is covered in the groove 140; the near-eye display module 300 also includes an electrical wire 212 and a circuit board (adapter board) 410, the circuit board or adapter board 410 is located outside the fixing seat 230, the fixing seat 230 is provided with a first through hole 231, the electrical wire 212 is passed through the first through hole 231 to electrically connect the micro display 210 and the circuit board 410, the temples 60 are provided with electrical devices, and the circuit board 410 is electrically connected to the electrical devices.

[0178] The first through-hole 231 accommodates the electrical conductor 212, thereby facilitating electrical connection with electrical components located within the temple 60, such as a power supply and a control board. The near-eye display device also includes a power module and a circuit board 410. The power module is electrically connected to the circuit board 410. The power module can be a button battery, etc. (not shown in the accompanying drawings). The power module can be fixed to the circuit board 410.

[0179] The electric energy of the power module is transmitted to the microdisplay 210 through the circuit board 410 and the electrical conductor 212. The microdisplay 210 is opposite to the light-transmitting through hole 2211 on the fixing base 230. The microdisplay 210 is fixedly connected to the optical module 220. When the optical module 220 moves relative to the bracket 301, the microdisplay 210 moves synchronously with the optical module 220. The microdisplay 210 and the optical module 220 can be fixedly connected by means of snap connection, screw connection, etc. The power module and the circuit board 410 are fixed to the frame 10, wherein the microdisplay 210 is electrically connected to the circuit board 410 via the electrical conductor 212. When the microdisplay 210 moves relative to the bracket 301 along with the optical module 220, the electrical conductor 212 will deform due to the change in the position of the microdisplay 210, thereby adapting to the change in the position of the microdisplay 210. For example, the power module and the circuit board 410 may be disposed near the second position: when the optical module 220 is in the first position, the electrical wire 212 is in an extended state; when the optical module 220 moves toward the second position, the electrical wire 212 bends.

[0180] The positional relationship between the microdisplay 210, the electrical conductors 212, and the circuit board 410 can be adjusted as needed. As shown in FIG30 , in this embodiment, the microdisplay 210, the electrical conductors 212, and the circuit board 410 are arranged in a straight line. In other embodiments, the microdisplay 210, the electrical conductors 212, and the circuit board 410 are stacked in sequence.

[0181] As shown in FIG30 , a transparent cover plate 340 is detachably provided on the bracket 301 , wherein the optical module 220 is located between the micro display 210 and the cover plate 340 . The cover plate 340 can protect the optical module 220 .

[0182] The above description is only an implementation method of the embodiment of the present application, and does not limit the patent scope of the embodiment of the present application. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can make equivalent structural or equivalent process changes using the description and drawings of the embodiment of the present application, or directly or indirectly apply them in other related technical fields. Without departing from the scope of protection of the purpose of this application and the claims, many forms can be made, which are also included in the patent protection scope of the embodiment of the present application.
