Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0033] The near-eye display device may include VR, AR, MR or XR, etc. The near-eye display device may be a display device with a near-eye display function installed on an ordinary optical lens, or a display device with a near-eye display function set on a processed optical lens. The near-eye display device may also be other devices with a near-eye display device set on a head-mounted device. In the example of the present application, a near-eye display device with an optical lens is used as an example for explanation. The processed optical lens described in the example of the present application may be a lens with functions such as an optical waveguide and a holographic waveguide. It is understandable that the near-eye display device in the example of the present application may also include other functional components. For example, the near-eye display device may be a head-mounted display device, and the near-eye display device may also include temples for connecting optical lenses or other support structures that can support the optical lenses on the head so that the optical lenses can be maintained in a preset position.

[0034] See also Figures 1 to 6The present application proposes an example of a near-eye display device 100, including a main body 10, a near-eye display module 200, a camera module 300, a first power module 140, a first coil 130 and a second coil 350; the near-eye display module 200 is connected to the main body 10; the camera module 300 is connected to the near-eye display module 200 or the main body 10; the first power module 140 is connected to the near-eye display module 200 or the main body 10; the first coil 130 is arranged on the main body 10, and the first coil 130 is electrically connected to the first power module 140; the second coil 350 is electrically connected to the camera module 300, and the second coil 350 is used for mutual induction with the first coil 130, so as to enable wireless power supply between the camera module 300 and the first power module 140.

[0035] like Figure 1 and Figure 2 As shown, the main body 10 can serve as a supporting structure of the near-eye display device. The main body 10 in this example may include a frame 110 , temples 120 connected to the frame 110 , and optical lenses 160 mounted on the frame 110 .

[0036] Please refer to Figure 3 , Figure 4 and Figure 5 The near-eye display module 200 is installed on the main body 10. The near-eye display module 200 in this example can be installed on the optical lens 160 or on the frame 110. The following is an example in which the near-eye display module 200 is installed on the optical lens 160. The near-eye display module 200 may include an optical machine, which may include a micro display, such as 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 these technologies. It is understood that the optical machine may also include a micro-optical module, etc. The micro-optical module is arranged in front of the micro display, and the light of the display is emitted after passing through the micro-optical module. Please refer to Figure 6In this example, the near-eye display module 200 can be installed on the human eye side 111 of the optical lens 160, and the light can be projected directly to the human eye; optionally, the near-eye display module 200 can be installed on the environment side 112 of the optical lens 160, and the light can pass through the optical lens 160 and be projected to the human eye.

[0037] Please continue reading Figure 6 , the camera module 300 is connected to one of the near-eye display module 200 or the main body 10, so that the camera module 300 can be installed at a preset position on the main body 10. When the camera module 300 is installed on the near-eye display module 200, after the near-eye display module 200 is installed at the preset position on the main body 10, the position of the camera module 300 relative to the main body 10 is relatively determined, and the camera module 300 can obtain information on the environment side 112 or the human eye side 111 of the optical lens 160. By obtaining information on the environment side 112 or the human eye side 111 of the optical lens 160 through the camera module 300, the display scene of the near-eye display device 100 can be expanded. The camera module 300 in this example can also be installed on the main body 10. Optionally, the near-eye display module 200 can be used to display the image obtained by the camera module 300, and the near-eye display module 200 can also be used to display the image transmitted by the main body 10.

[0038] The first power module 140 is connected to the near-eye display module 200 or the main body 10, and the first power module 140 can be used as a functional module for supplying power to the camera module 300. Optionally, in this example, the first power module 140 can be a battery, and the first power module 140 can be installed on the near-eye display module 200, and the first power module 140 can also be installed on the main body 10. The battery described in the example of the present application can be a primary battery or a secondary battery, wherein the secondary battery is a rechargeable battery.

[0039] The first coil 130 is disposed on the main body 10, which means that the first coil 130 is a coil structure installed on the main body 10. The first coil 130 is electrically connected to the first power module 140 so that the first coil 130 can form a loop with the first power module 140. Optionally, the first coil 130 can be disposed on the optical lens 160 of the main body 10, and the first coil 130 can be disposed around the optical lens 160. When the main body 10 has multiple optical lenses 160, the first coil 130 can be a coil structure surrounding one of the optical lenses 160, and the first coil 130 can also surround multiple optical lenses 160 at the same time; optionally, at least one first coil 130 can be disposed on each optical lens 160.

[0040] The second coil 350 is electrically connected to the camera module 300 so that the second coil 350 can form a loop with the camera module 300, and the second coil 350 and the first coil 130 can be mutually inductive, so that the first power module 140 can power the camera module 300 by wireless induction. The second coil 350 in this example can be a coil surrounding the outside of the camera module 300, and the second coil 350 can also be integrated inside the camera module 300. The number of turns of the second coil 350 in this example can be the same as the number of turns of the first coil 130, and the number of turns of the second coil 350 can also be different from the number of turns of the first coil 130.

[0041] In this example, the first coil 130 and the second coil 350 are inductively coupled to each other. The cooperation between the camera module 300 and the first power module 140 allows the first power module 140 to power the camera module 300, and also allows the first power module 140 to be charged through the camera module 300. When the first power module 140 is installed on the near-eye display module 200 and a power supply device such as a battery is connected to the camera module 300, the second coil 350 on the camera module 300 and the first coil 130 are inductively coupled to each other, so as to wirelessly charge the first power module 140.

[0042] In this example, by using the inductive charging method of the first coil 130 and the second coil 350, the camera module 300 can be wirelessly powered, so that the assembly and wiring of the camera module 300 can be relatively simple, which helps to simplify the structure of the camera module 300 and improve the convenience of installing the camera module 300. Since the camera module 300 can be wirelessly powered, when the position of the camera module 300 is adjusted, the first coil 130 can cooperate with the second coil 350, so that the installation position of the camera module 300 can be more variable, so that the camera module 300 can be normally powered at different positions, so as to reduce the impact of the power supply method on the camera module 300 and improve the flexibility of the installation position of the camera module 300.

[0043] Please refer to Figure 6 and Figure 7 In some examples, the camera module 300 includes a first shell 320 and a camera assembly 340, the first shell 320 forms a first accommodating cavity 330; the second coil 350 is disposed in the first accommodating cavity 330; the camera assembly 340 is disposed in the first accommodating cavity 330 and is electrically connected to the second coil 350.

[0044] The first housing 320 can be used as the external structure of the camera module 300. The interior of the first housing 320 is at least partially hollow, so that the first housing 320 forms a first accommodating chamber 330. The first accommodating chamber 330 is used to accommodate the camera assembly 340. The camera assembly 340 in this example is a component used to obtain images in the camera module 300. The camera assembly 340 may include functional components such as a lens, a sensor, and an image processing chip. In this example, the second coil 350 is arranged in the first accommodating chamber 330. The second coil 350 can be arranged close to the camera assembly 340, or the second coil 350 can be arranged spaced apart from the camera assembly 340. The second coil 350 is electrically connected to the camera assembly 340 so that the coil 350 can be used to power the camera assembly 340.

[0045] In some examples, the second coil 350 is disposed around the periphery of the camera assembly 340. The second coil 350 is formed with an annular region, and the camera assembly 340 can be disposed within the annular region of the second coil 350.

[0046] In some examples, the second coil 350 is arranged in parallel with the camera assembly 340, the camera module 300 has an axis direction, and the axis of the second coil 350 can be parallel to or coincide with the axis of the camera module 300. Since the second coil 350 can be arranged around the camera assembly 340, the gap between the first housing 320 and the camera assembly 340 can be fully utilized, the space utilization rate in the camera module 300 is improved, and the volume of the camera module 300 is reduced.

[0047] Please refer to Figure 7 In some examples, the first power module 140 is connected to the main body 10; the near-eye display device 100 also includes a second power module 500, the second power module 500 is connected to the near-eye display module 200, and the second coil 350 is electrically connected to the second power module 500.

[0048] The first power module 140 is connected to the main body 10 so that the first power module 140 can be integrated at a preset position on the main body 10, so as to facilitate the miniaturization design of the near-eye display module 200. In this example, taking smart glasses as an example, the first power module 140 can be integrated on the frame 110, and the first power module 140 can also be integrated on the temple 120. Taking the first power module 140 being set on the temple 120 as an example, since the space on the temple 120 of the smart glasses is relatively sufficient, the space on the temple 120 can be fully utilized in this example; the first coil 130 can be arranged around the optical lens 160, and the first power module 140 can be electrically connected to the first coil 130 through a flexible circuit board or a wire. In some examples, a plurality of first coils 130 can be arranged on the main body 10, and a first coil 130 can be respectively arranged on the periphery of each optical lens 160, and a first power module 140 can also be respectively arranged on each temple 120.

[0049] The second power module 500 is connected to the near-eye display module 200. The second power module 500 can be used as a self-contained power supply for the near-eye display module 200, and the second power module 500 can be a battery. In this example, the second power module 500 is electrically connected to the second coil 350 so that the first power module 140 can charge the second power module 500 by wireless charging. In this example, the camera module 300 can be installed on the near-eye display module 200 so that the camera module 300 and the near-eye display module 200 form a whole. When adjusting the relative position of one of the near-eye display module 200 or the camera module 300 on the main body 10, the other can move synchronously. Optionally, the second power module 500 can also be electrically connected to the camera module 300 so that when the first power module 140 stops wireless power supply, the camera module 300 is powered by the second power module 500.

[0050] In some examples, the camera module 300 is movably connected to the near-eye display module 200 or the main body 10. The main body 10 includes a frame 110 and a temple 120, the first coil 130 is disposed on the frame 110; the temple 120 is connected to the frame 110, the first power module 140 is disposed on the temple 120, and the first power module 140 includes a rechargeable power source; the temple 120 is provided with a first electrical interface 150, the first electrical interface 150 is electrically connected to the first coil 130, and / or the first electrical interface 150 is electrically connected to the first power module 140.

[0051] The camera module 300 can be moved relative to the near-eye display module 200 or the main body 10, which means that the camera module 300 can be adjusted relative to the near-eye display module 200 or the main body 10, and the adjustment includes position adjustment and angle adjustment. In this example, by adopting a camera module 300 that can be moved relative to the near-eye display module 200 or the main body 10, the field of view of the camera module 300 can be changed by adjusting the relative position or angle of the camera module 300, and then images at different positions can be obtained to expand the use scenario of the near-eye display device 100. The movable connection in this example may include a slidable connection, a rotatable connection, or a connection method that cooperates sliding and rotating, and may also include other connection methods that allow the camera module 300 to move relative to the near-eye display module 200 or the main body 10. Optionally, the camera module 300 can be movably connected to the near-eye display module 200, and the near-eye display module 200 can be used as an intermediate connection between the camera module 300 and the main body 10. When the position of the near-eye display module 200 on the main body 10 is adjusted, the position of the camera module 300 can also be adjusted synchronously. Optionally, the camera module 300 can be movably connected to the main body 10, and the camera module 300 can move relative to the main body 10.

[0052] Please refer to Fig.10 , Fig.11 and Fig.12 In this example, the frame 110 and the temples 120 can remain in a relatively fixed state, and the temples 120 can also be movable relative to the frame 110, and the frame 110 can be used to install optical lenses. The first electrical interface 150 is electrically connected to at least one of the first coil 130 and the first power module 140. The first electrical interface 150 can be used to connect an external power source to power the first power module 140, or the first coil 130 can be directly connected to an external power source to wirelessly power the camera module 300 or the near-eye display module 200. The first electrical interface 150 in this example can be a USB interface or other interface forms. In this example, one or more first coils 130 can be set on the frame 110, and the number of the first power module 140 can be one or more.

[0053] In some examples, the main body 10 has a human eye side 111 and an environmental side 112, the camera module 300 has a first position facing the human eye side 111 of the main body 10 and a second position facing the environmental side 112 of the main body 10, and the camera module 300 is rotatably connected to the near-eye display module 200 or the main body 10 between the first position and the second position; the camera module 300 is used to obtain human eye signals at the first position and to obtain environmental signals at the second position; the near-eye display device 100 also includes an electric control board 400, and the near-eye display module 200 and the camera module 300 are respectively electrically connected to the electric control board 400, and the electric control board 400 is used to control the operation of the near-eye display module 200 according to the human eye signal or the environmental signal.

[0054] The camera module 300 has a first position and a second position, wherein when the camera module 300 is in the first position, the camera module 300 faces the human eye side 111 of the optical lens 160, so that the camera module 300 can obtain the image of the human eye side 111 of the optical lens 160; when the camera module 300 is in the second position, the camera module 300 faces the environment side 112 of the optical lens 160, and the camera module 300 can obtain the environment signal of the environment side 112. The camera module 300 is rotatably connected to the near-eye display module 200 between the first position and the second position, which means that the camera module 300 is rotatably connected to the near-eye display module 200, and the camera module 300 can rotate between the first position and the second position. In some examples, the camera module 300 is rotatably connected to the near-eye display module 200 through the rotating connection member 310, wherein the rotating connection member 310 can be a rotating shaft, or other functional structures that can be used to rotatably connect the camera module 300 and the near-eye display module 200 to each other. Optionally, when the camera module 300 in this example is in the first position or the second position, the camera module 300 may be in an opposite state, and the opposite state means that the position of the camera is completely opposite. Optionally, the first position and the second position in this example may be fixed positions, and the first position and the second position may also be the position range of the camera module 300 in the corresponding direction. In this example, the image information of the human eye side 111 obtained by the camera module 300 at the first position is a human eye signal, and the human eye signal may include at least one of the pupil size, pupil position and blinking frequency of the human eye. When one of the pupil size, pupil position and blinking frequency is different from the preset value, it means that the current user may be in a fatigue state, or the user may not use the near-eye display module normally. In the example of this application, when the pupil of the human eye is blocked, such as in a fatigue state, the pupil may be blocked, and in the human eye signal obtained by the camera module 300, the pupil size will be different from the pupil size in the normal state. When the visual axis of the human eye is not aligned with the near-eye display module, the pupil position is also different from the position in the normal use state. When the blinking frequency of the human eye is greater than the frequency in the normal state, it means that the human eye may be in a fatigued state. In this example, the pupil size, blinking frequency and pupil position of the human eye in the normal state can be preset values ​​pre-saved according to the normal state, or can be an average value according to the normal state of the user. The environmental signal in this example is the information of the environment side 112, and the environmental signal obtained by the camera module 300 can be an image of the environment.

[0055] The electric control board 400 may be a circuit board. The electric control board 400 in the example of the present application may be composed of an integrated circuit arranged on a single circuit board. The electric control board 400 may also be formed by a combination of multiple circuit boards each having a circuit structure integrated therein. The camera module 300 and the near-eye display module 200 are respectively connected to the electric control board 400 by electrical signals, which means that the camera module 300 and the near-eye display module 200 are respectively connected to the electric control board 400 by wire or wireless means, so that the camera module 300 and the near-eye display module 200 transmit electrical signals to the electric control board 400, and the camera module 300 and the near-eye display module 200 may also perform charging operations with the electric control board 400. The electric control board 400 can control the operation of the near-eye display module 200 according to the human eye signal or the environmental signal, which means that the electric control board 400 can control the current operation mode of the near-eye display module 200 according to the human eye signal or the environmental signal obtained by the camera module 300. For example, the camera module 300 obtains the blinking frequency information in the human eye signal. When the blinking frequency is greater than the first preset signal threshold, it means that the user may be in a fatigue state. The electric control board 400 can control the near-eye display module 200 to enter a power saving mode or a sleep mode; when the blinking frequency is within the first preset signal threshold, it means that the user may be in a normal use state. The electric control board 400 can control the near-eye display module 200 to maintain a normal display state. The camera module 300 obtains the environmental signal, and the electric control board 400 can also control the near-eye display module 200 to project the environmental signal to the human eye.

[0056] Please refer to Figure 7 In some examples, the near-eye display device 100 also includes a third coil 230, which is electrically connected to the near-eye display module 200, and the third coil 230 is used for mutual induction with the first coil 130 to enable wireless power supply between the near-eye display module 200 and the first power module 140.

[0057] The third coil 230 serves as an induction coil between the first power module 140 and the near-eye display module 200. The third coil 230 is electrically connected to the near-eye display module 200 so that the third coil 230 and the first coil 130 are mutually inductive, and the first power module 140 can be used to power the near-eye display module 200. The third coil 230 in this example can be arranged around the periphery of the near-eye display module 200, and the third coil 230 can also be installed on the inner side of the near-eye display module 200. By using the third coil 230 to cooperate with the first coil 130, wireless power can be provided between the near-eye display module 200 and the first power module 140. The number of coil turns of the third coil 230 in this example can be the same as the number of coil turns of the first coil 130, and the number of coil turns of the third coil 230 can also be different from the number of coil turns of the first coil 130. When the first power module 140 is installed on the near-eye display module 200 , the first coil 130 may be installed on the main body 10 and electrically connected to the first power module 140 .

[0058] In this example, the first coil 130 and the third coil 230 are inductively coupled to each other. The cooperation between the near-eye display module 200 and the first power module 140 can provide power to the near-eye display module 200 for the first power module 140, and can also charge the first power module 140 through the near-eye display module 200. When the first power module 140 is installed on the near-eye display module 200 and a power supply device such as a battery is connected to the near-eye display module 200, the third coil 230 on the near-eye display module 200 can be inductively coupled to the first coil 130, so as to be used for wirelessly charging the first power module 140.

[0059] In this example, by adopting the inductive charging method of the first coil 130 and the third coil 230, the near-eye display module 200 can be wirelessly powered, so that the assembly and wiring of the near-eye display module 200 can be relatively simpler, which helps to simplify the structure of the near-eye display module 200 and improve the convenience of installation of the near-eye display module 200. Since the near-eye display module 200 can be wirelessly powered, when the position of the near-eye display module 200 is adjusted, the first coil 130 can cooperate with the third coil 230, so that the installation position of the near-eye display module 200 can be more variable, so that the near-eye display module 200 can also be normally powered when it is in different positions, so as to reduce the impact of the power supply method on the near-eye display module 200.

[0060] Please refer to Figure 8 and Fig. 9In some examples, the near-eye display module 200 includes a second shell 210 and a display component 220, the second shell 210 is formed with a second accommodating cavity 211 and a light outlet 212 connected to the second accommodating cavity 211, the third coil 230 is disposed in the second accommodating cavity 211, and the first power module 140 is connected to the second shell 210; the display component 220 is at least partially disposed in the second accommodating cavity 211, and a light outlet surface is formed at a position of the display component 220 corresponding to the light outlet 212.

[0061] The second shell 210 can be used as the outer shell structure of the near-eye display module 200, and the second shell 210 is at least partially hollow to form a second accommodating chamber 211. The second accommodating chamber 211 can be used to accommodate at least part of the display assembly 220. The second accommodating chamber 211 has a light outlet 212, and the light outlet 212 is a through hole connecting the second accommodating chamber 211 and the outside of the second shell 210. The camera module 300 can be rotatably connected to the second shell 210 so that the camera module 300 can be rotated and switched between a first position and a second position relative to the second shell 210. The second shell 210 in this example can be an integrally formed second shell 210 structure, and the second shell 210 can also be composed of a plurality of shell components.

[0062] The display assembly 220 may include the optical machine described above, and the display assembly 220 is used to project a light beam to the human eye. The display assembly 220 has a light emitting surface. In this example, the light emitting surface of the display assembly 220 is arranged on the same side as the light outlet 212 of the second shell 210, so that the light emitting surface of the display assembly 220 can be arranged corresponding to the position of the light outlet 212, and the light projected by the display assembly 220 can be output to the human eye through the light outlet 212. The display assembly 220 is connected to the second shell 210, which means that the display assembly 220 is connected to the second shell 210. The display assembly 220 can be directly connected to the second shell 210, and the display assembly 220 can also be connected to the second shell 210 through an intermediate connecting member, so that the display assembly 220 can form an integral structure with the second shell 210. In this example, the display assembly 220 can be rotatably connected to the camera module 300, so that the camera module 300 can be rotated and switched between the first position and the second position relative to the display assembly 220. The display assembly 220 in this example is at least partially located in the second accommodation cavity 211, so as to limit and fix the display assembly 220. The light emitting surface in this example is the surface when the light beam of the display assembly 220 is output when the display assembly 220 is in operation. The display assembly 220 in this example is electrically connected to the electric control board 400, so that the electric control board 400 and the display assembly 220 can communicate and / or charge each other.

[0063] In some examples, an annular area is formed inside the third coil 230 , and at least part of the display component 220 is located within the annular area of ​​the third coil 230 .

[0064] The display assembly 220 in this example can be partially located in the annular area inside the third coil 230, so that the third coil 230 can be located in the gap between the display assembly 220 and the second housing 210, which can make full use of the internal space of the second housing 210 on the one hand; on the other hand, it can help reduce the volume of the near-eye display module 200 to reduce the foreign body sensation of the near-eye display module 200 on the optical lens 160. The display assembly 220 in this example can also be completely located in the annular area inside the third coil 230. In some examples, along the axial direction of the third coil 230, the thickness of the display assembly 220 can be less than or equal to the total height of the third coil 230, and then in the internal space of the second accommodating cavity 211, the space of the second accommodating cavity 211 is fully utilized.

[0065] In some examples, the display component 220 includes a display unit 221 and an optical unit 224 , the display unit 221 is at least partially disposed in the second accommodating cavity 211 ; the optical unit 224 is at least partially disposed in the second accommodating cavity 211 , and the optical unit 224 is at least partially located in the annular area of ​​the third coil 230 .

[0066] The display unit 221 is used to output a light beam. The display unit 221 in this example may include at least one of the Micro-LED, uLED, Micro-oled, LCoS, LCD, DMD / DLP or LBS described above, or may be other functional modules that can be used to output a light beam in the near-eye display module 200. The display unit 221 in this example may be rotatably connected to the camera module 300. The display unit 221 is electrically connected to the electric control board 400 so that the display unit 221 can communicate with the electric control board 400 or charge each other.

[0067] The optical unit 224 may be composed of a lens or a lens group. The optical unit 224 forms the light emitting surface described in the above example. In this example, the optical unit 224 may be arranged corresponding to the position of the display unit 221, so that the light beam output by the display unit 221 may be processed by the optical unit 224 and projected to the direction of the human eye. Optionally, the optical unit 224 may also be a lens group composed of a plurality of lenses, wherein the plurality of lenses in the lens group form an integral structure, and the combination mode and position of the plurality of lenses in the lens group may be selected as required. The optical unit 224 is located in the annular area of ​​the third coil 230, and the third coil 230 may be arranged around the periphery of the optical unit 224. Optionally in this example, along the axial direction of the third coil 230, the optical unit 224 may be completely located inside the annular structure of the third coil 230.

[0068] In some examples, the display unit 221 includes a microdisplay 222 and an electrical adapter plate 223 ; the microdisplay 222 is disposed on a side of the optical unit 224 away from the light outlet 212 ; and the first power module 140 is electrically connected to the microdisplay 222 via the electrical adapter plate 223 .

[0069] The micro display 222 can be at least one of the Micro-LED, uLED, Micro-oled, LCoS, LCD, DMD / DLP or LBS mentioned above, or can be other functional modules that can be used to output light beams in the near-eye display module 200. The micro display 222 is arranged on the side of the optical unit 224 away from the light outlet 212, and the micro display 222 is used to project a light beam to the optical unit 224, and the light beam is processed by the optical unit 224 and projected to the human eye. The near-eye display device 100 also includes an electric control board 400, which is arranged in the second accommodating cavity 211, and the electric control board 400 is electrically connected to the micro display 222 through the electrical adapter board 223.

[0070] The electrical adapter board 223 can be used to connect the micro display 222 with the electronic control board 400 by electrical signals. The electrical adapter board 223 can be connected to the micro display 222 by electrical signals through structures such as wires or flexible circuit boards. The electrical adapter board 223 in this example can serve as an intermediate connector between the micro display 222 and the electronic control board 400. The electronic control board 400 in this example can serve as a main control circuit board of the near-eye display device 100.

[0071] In some examples, the direction from the environment side 112 to the human eye side 111 is the first direction 3 a , and the display unit 221 and the optical unit 224 are located on the same side of the electric control board 400 along the first direction 3 a .

[0072] The direction from the environment side 112 to the human eye side 111 is the first direction 3a. In this example, the environment side 112 and the human eye side 111 can be the outer sides of the two opposite walls of the optical lens 160. It can be understood that the first direction 3a in the example of the present application can be bidirectional, and the direction from the human eye side 111 to the environment side 112 can also be the first direction 3a.

[0073] In this example, the display unit 221 and the optical unit 224 are located on the same side of the electric control board 400 along the first direction 3 a to fully utilize the space in the second accommodating cavity 211 and reduce the installation space required between the display unit 221 and the optical unit 224 .

[0074] In some examples, the micro display 222 and the electrical adapter plate 223 are arranged along the second direction 3 b , and the second direction 3 b is arranged at an angle to the first direction 3 a .

[0075] The electrical adapter plate 223 and the micro display 222 are arranged along the second direction 3b so that the electrical adapter plate 223 and the micro display 222 can utilize the space in the second accommodating cavity 211 along the second direction 3b, so as to reduce the width of the shell along the first direction 3a. When the near-eye display module is on the optical lens 160, the protrusion and foreign body sensation of the near-eye display module in the first direction 3a can be reduced. When the near-eye display module 200 is located on the human eye side 111 of the optical lens 160, the intrusion of the near-eye display module to the human eye can be reduced.

[0076] In some examples, the second housing 210 is movably connected to the main body 10 .

[0077] The second shell 210 is movably connected to the main body 10, which means that the second shell 210 is connected to the main body 10 and can move relative to the main body 10. The movable connection in this example may include a slidable connection, a rotatable connection, or a connection method that cooperates sliding and rotating, and may also include other connection methods that allow the near-eye display module 200 to move relative to the main body 10. In this example, by adopting a movable second shell 210, when the second shell 210 moves relative to the main body 10, the position of the light beam output by the near-eye display module 200 can produce synchronous movement, and then the light output position of the near-eye display module 200 can be adjusted as needed to better adapt the position of the projected light beam of the near-eye display module 200 to the visual axis of the human eye.

[0078] In some examples, the near-eye display device 100 also includes a first connection portion 600 and a second connection portion 700; the first connection portion 600 is connected to the second shell 210, and the first connection portion 600 is used to connect to one of the environmental side 112 or the human eye side 111 of the main body 10; the second connection portion 700 is arranged on one side of the first connection portion 600 along the first direction 3a, and is arranged opposite to the first connection portion 600, and the second connection portion 700 is used to connect to the other of the environmental side 112 or the human eye side 111 of the main body 10; wherein the first connection portion 600 and the second connection portion 700 are used to clamp the main body 10 and allow the second shell 210 to move on the main body 10.

[0079] The first connection part 600 is connected to the housing, which means that the first connection part 600 is directly or indirectly connected to the housing. The first connection part 600 is used to connect to one of the environmental side 112 or the human eye side 111 of the optical lens 160, and the second connection part 700 is used to connect to the other of the environmental side 112 or the human eye side 111 of the optical lens 160, so that the first connection part 600 and the second connection part 700 can be located on the environmental side 112 and the human eye side 111 of the optical lens 160 respectively, and the first connection part 600 and the second connection part 700 can form a clamping structure on the environmental side 112 and the human eye side 111 of the optical lens 160 to clamp the near-eye display module on the optical lens 160. When the first connection part 600 and the second connection part 700 are relatively moved, the housing can move synchronously to adjust the light emitting position of the near-eye display module so that the light emitting position of the near-eye display module is better adapted to the optical axis of the human eye.

[0080] In some examples, the near-eye display device 100 includes the second power module 500 described in any of the above examples, the second power module 500 is disposed in the near-eye display module 200, the second power module 500 is at least partially disposed in the second accommodating cavity 211, and the first connecting portion 600 and the light outlet 212 are disposed on the same side of the second power module 500 along the first direction 3a. In this example, by making the second power module 500 at least partially located in the second accommodating cavity 211, the internal space of the second accommodating cavity 211 can be fully utilized, and the second power module 500 can be used as the internal power supply of the near-eye display module 200. In this example, the first connecting portion 600 and the light outlet 212 are disposed on the same side of the second power module 500 along the first direction 3a to fully utilize the internal space of the second accommodating cavity 211.

[0081] In some examples, the first connection portion 600 is at least partially disposed in the second accommodating cavity 211, and the first connection portion 600 can be mutually connected with the housing by snapping, embedding, bonding or other methods, and the first connection portion 600 is at least partially disposed in the second accommodating cavity 211, so as to make full use of the internal space of the second accommodating cavity 211 and reduce the volume of the near-eye display module 200. In this example, the first connection portion 600 and the optical unit 224 can be arranged on the housing along the second direction 3b, so as to limit the first connection portion 600 and the optical unit 224.

[0082] In some examples, one of the first connection part 600 and the second connection part 700 is a magnetic material, and the other is a magnetically absorbable material. One of the first connection part 600 and the second connection part 700 is a magnetic material, which means that one of the first connection part 600 and the second connection part 700 contains a magnetic material. Taking the first connection part 600 as an example, the first connection part 600 can be a magnetic structure as a whole, and the first connection part 600 can also be a structure containing a magnetic material and having a magnetic absorption performance. The magnetically absorbable material means that the structure can be adsorbed by a magnetic material. The magnetically absorbable material can be a material containing a magnetic material, and the magnetically absorbable material can also be a material that can be magnetically absorbed and contains an iron-based alloy, Mn-Zn ferrite, Ni-Zn ferrite and a composite material. In this example, one of the first connection part 600 and the second connection part 700 is a magnetic material so that it can generate a magnetic adsorption force, and the other is a magnetically absorbable material so that it can be magnetically absorbed. In this example, by using a combination of magnetic material and magnetically absorbable material, the first connecting part 600 and the second connecting part 700 can be respectively adsorbed on the human eye side 111 and the environmental side 112 of the optical lens 160. Since magnetic adsorption is used, no additional connecting parts are required between the first connecting part 600 and the second connecting part 700, and the positions of the first connecting part 600 and the second connecting part 700 on the optical lens 160 can be easily adjusted.

[0083] In some examples, the second shell 210 has a first surface 213 on one side in the first direction 3a, and the light outlet 212 is a through hole penetrating the first surface 213; a positioning portion 215 is provided on the first surface 213, and the positioning portion 215 is arranged around the outer periphery of the light outlet 212, and the optical unit 224 is at least partially arranged in the positioning portion 215.

[0084] The first surface 213 is one of the surfaces of the housing, and the first surface 213 is disposed on one side of the housing in the first direction 3a. In this example, the first surface 213 can be used as a surface of the housing facing the human eye. The light outlet 212 is a through hole penetrating the first surface 213, so that the light outlet 212 is connected to the second accommodating cavity 211.

[0085] A positioning portion 215 is provided on the first surface 213, and the positioning portion 215 may be an annular structure protruding from the first surface 213. The positioning portion 215 is arranged around the outer periphery of the light outlet 212, so that the positioning portion 215 forms an annular protruding structure at the position of the light outlet 212 on the first surface 213. The optical unit 224 is at least partially arranged in the positioning portion 215, so that the optical unit 224 can cooperate with the positioning portion 215 to limit the movement of the optical unit 224 relative to the housing. The positioning portion 215 in this example can form a space to limit the movement of the optical unit 224 along the second direction 3b. The positioning portion 215 surrounds the outer periphery of the optical unit 224, and can also play a role in reducing light leakage of the optical unit 224.

[0086] In some examples, the second shell 210 has a second surface 214 arranged opposite to the first surface 213 along the first direction 3a, and the first connecting portion 600 is connected to the first surface 213; a section perpendicular to the first surface 213 is defined as a first section; in the first section, along the first direction 3a, the distance between an end of the first connecting portion 600 away from the second surface 214 and the second surface 214 is a first distance 8a; along the first direction 3a, the distance between the light emitting surface and the second surface 214 is a second distance 8b, and the first distance 8a is not less than the second distance 8b.

[0087] The second surface 214 is a surface on the shell, and the second surface 214 is arranged opposite to the first surface 213. In this example, the second surface 214 can be the surface of the shell facing the environment side 112. The first cross section is a cross section perpendicular to the first surface 213. In this example, the first cross section can be a plane parallel to the second direction 3b as shown in the figure. Taking the figure as an example, along the first direction 3a, the distance between the end of the first connecting portion 600 away from the second surface 214 and the second surface 214 is the first distance 8a, the light-emitting surface can be on the same plane as the end of the positioning portion 215 away from the second surface 214, and the distance between the light-emitting surface and the second surface 214 is the second distance 8b, and the first distance 8a is not less than the second distance 8b, that is, the first connecting portion 600 can be more protruding from the first surface 213 of the shell relative to the positioning portion 215. When the first connecting portion 600 is installed on the optical lens 160, the positioning portion 215 can be relatively suspended on the surface of the optical lens 160 to reduce the wear of the positioning portion 215 on the optical lens 160.

[0088] In some examples, the difference from the previous example is that the distance between the end of the camera module 300 away from the second surface 214 and the second surface 214 is a third distance 8c, and the third distance 8c is less than the first distance 8a. The third distance 8c between the end of the camera module 300 away from the second surface 214 and the second surface 214 is less than the first distance 8a, so that the first connecting portion 600 is relatively protruding from the first surface 213 in the first direction 3a. When the near-eye display module is installed on the optical lens 160, the camera module 300 does not contact the surface of the optical lens 160, which can reduce the wear on the optical lens 160 on the one hand; on the other hand, when the camera module 300 rotates and switches between the first position and the second position, the interference between the optical lens 160 and the camera module 300 can be reduced.

[0089] In some examples, the difference from the previous example is that the height of the camera module 300 along the first direction 3a is less than the distance from the first surface 213 to the second surface 214. The height of the camera module 300 along the first direction 3a is 8d. In this example, the height of the camera module 300 along the first direction 3a is limited so that the height of the camera module 300 in the first direction 3a is less than the height of the housing in the first direction 3a. When the camera module 300 is installed on the near-eye display module 200, the camera module 300 can have a larger activity space between the first position and the second position. On the one hand, the mutual interference between the camera module 300 and the optical lens 160 can be reduced, and on the other hand, the position adjustment of the camera module 300 is facilitated.

[0090] In some examples, the first power module 140 is connected to the main body 10; the near-eye display device 100 also includes a second power module 500 and a third coil 230; the second power module 500 is connected to the near-eye display module 200; the second coil 350 is electrically connected to the second power module 500 to enable wireless power supply between the camera module 300 and the second power module 500; the third coil 230 is electrically connected to the near-eye display module 200 and the second power module 500, respectively; the third coil 230 is used for mutual induction with the first coil 130 to enable wireless power supply between the near-eye display module 200 and the first power module 140, or to enable wireless power supply between the near-eye display module 200 and the second power module 500. In this example, the first power module 140 can be a battery connected to the main body 10. Taking smart glasses as an example, the first power module 140 can be a battery structure arranged on the temple 120 of the smart glasses, and the first coil 130 can be a coil structure at a preset position around the frame 110; the first power module 140 can be electrically connected to the first coil 130 through a wire or a flexible row. The second power module 500 can be used as a built-in battery of the near-eye display module 200. The second power module 500 is electrically connected to the second coil 350 and the third coil 230 respectively, so that the second power module 500 can form a loop with the second coil 350 or the third coil 230. The first coil 130 can be mutually inductive with the second coil 350, and the first coil 130 can also be mutually inductive with the third coil 230. When the first coil 130 and the second coil 350 are mutually inductive, the first coil 130 and the second coil 350 can be used to enable the first power module 140 to wirelessly charge the camera module 300. When the first coil 130 and the third coil 230 are inductively coupled to each other, the first coil 130 and the third coil 230 can be used to enable the first power module 140 to wirelessly power the near-eye display module 200, or the first power module 140 can wirelessly charge the second power module 500 through the cooperation of the first coil 130 and the third coil 230. When the camera module 300 is connected to the near-eye display module 200, the second coil 350 can also be electrically connected to the second power module 500, so that the first power module 140 can wirelessly charge the second power module 500 through the cooperation of the first coil 130 and the second coil 350.

[0091] See also Fig.13The present application also proposes an example of a charging box 800, which is used to charge the first power module 140 of the near-eye display device 100 described in any of the above examples. The charging box 800 includes a box body 840, and the box body 840 is provided with a fourth coil 810 and a second electrical interface 820. The second electrical interface 820 and the fourth coil 810 are electrically connected. The fourth coil 810 is used for mutual induction with the first coil 130 to charge the first power module 140 through the second electrical interface 820.

[0092] The box body 840 of the charging box 800 in this example may be in the shape of a rectangular parallelepiped, or may be in other shapes. In this example, the box body 840 has a fourth coil 810, which may be mutually inductive with the first coil 130, so that when the near-eye display device 100 is installed in a preset position of the charging box 800, the first power module 140 may be wirelessly charged through the second electrical interface 820.
