Description

Technical Field

[0001] The present application relates to the field of near-eye display technology, and in particular to a near-eye display device and a head-mounted device. Background Art

[0002] Near-eye display (NED) uses a display device placed within the human eye's non-photopic distance to render light field information to the human eye, thereby reconstructing a virtual scene directly in front of the human eye. NEDs can create virtual images in the field of view of one or both eyes. NEDs are typically used in conjunction with head-mounted devices such as glasses.

[0003] Taking glasses as an example, to mount a near-eye display, a large-diameter mounting hole is typically created in the frame. The near-eye display is then embedded within the frame and secured with glue. Due to the large number of components, near-eye displays are typically larger. Therefore, the frame must be larger to accommodate the mounting hole. This increased frame size also increases manufacturing cost and weight. Utility Model Content

[0004] The purpose of this application is to overcome the defects of the prior art and provide a near-eye display device to solve the problems in the prior art.

[0005] To solve the above problems, a first aspect of an embodiment of the present application provides a near-eye display device, which is applied to a head-mounted device, comprising:

[0013] A second aspect of the present application provides a head-mounted device, comprising a main body, the main body having a proximal end surface and a distal end surface, the proximal end surface and the distal end surface being disposed on either side of the main body, the proximal end surface facing the human eye side of the main body;

[0014] An electrical module is provided on the main body, and

[0015] The near-eye display device as described above includes a near-eye display module, a first electrical connection socket, and a second electrical connection socket, wherein the near-eye display module and the first electrical connection socket are configured to be releasably connected to a first position of the main body through a gap, the near-eye display module is further configured to be movably disposed on the near-eye end surface, and the first electrical connection socket is further configured to be movably disposed on the far-eye end surface;

The second electrical connector is connected to a battery module of the head-mounted device.

[0019] The near-eye display device is modularized, wherein different components of the near-eye display device can be releasably mounted at different locations on the head-mounted device, thereby rationally utilizing the space on the head-mounted device and enabling the near-eye display module to be detached from the head-mounted device. This eliminates the need to provide mounting holes (or mounting holes with large apertures) on the head-mounted device and increase the size of the head-mounted device, thereby enabling the near-eye display module to be detachably mounted on the head-mounted device.

[0038] Example

[0039] In this embodiment, a near-eye display device is proposed, which is applied to a head-mounted device, wherein the head-mounted device includes glasses, helmets, etc. Figure 1 , a near-eye display device includes:

[0040] Near-eye display module 200;

[0041] The first electrical connection base 310 is spaced apart from the near-eye display module 200 in a first direction to form a gap 201;

[0042] The second circuit board 320 extends in a first direction away from the near-eye display module 200 and is electrically connected to the near-eye display module 200 and the first electrical connection base 310 ;

[0043] The first circuit board 300 is electrically connected to the first electrical connection base 310. The first circuit board 300 extends in a second direction away from the first electrical connection base 310. The first direction and the second direction form an angle.

[0044] The second electrical connection socket 330 is located at an end of the first circuit board 300 and is electrically connected to the first circuit board 300 .

[0045] Reference Figure 1 , the first direction is parallel to the direction indicated by the arrow x, and the second direction is parallel to the direction indicated by the arrow y.

[0046] like Figure 2 and Figure 3 As shown, the near-eye display module 200 and the first electrical connection socket 310 are configured to be releasably connected to a first position of the head-mounted device through a gap 201; the second electrical connection socket 330 is configured to be releasably connected to a second position of the head-mounted device away from the first position. The second electrical connection socket 330 is electrically connected to the electrical module of the head-mounted device to electrically connect the electrical module and the near-eye display module 200. The structure of the near-eye display device is modularized, wherein different components of the near-eye display device are releasably mounted at different positions of the head-mounted device, thereby rationally utilizing the space on the head-mounted device and enabling the near-eye display module to be detached from the head-mounted device. Figure 2 , P1 represents the first position and P2 represents the second position.

[0047] In this embodiment, both the first circuit board 300 and the second circuit board 320 are flexible circuit boards, and both the first circuit board 300 and the second circuit board 320 can be strip-shaped structures. Specifically, the first circuit board 300 and the second circuit board 320 can be electrical conductors, such as flexible conductors. In other embodiments, the first circuit board 300 and the second circuit board 320 can also be flexible circuit boards including electrical components, with integrated electrical traces for electrically connecting the components.

[0048] The extension length of the second circuit board 320 in the first direction away from the near-eye display module 200 is less than the extension length of the first circuit board 300 in the second direction away from the first electrical connection seat 310, and the angle between the first direction and the second direction is less than or equal to 90°.

[0049] The first circuit board 300 is longer than the second circuit board 320, allowing the second electrical connector 330 to be installed on the head-mounted device away from the near-eye display module 200 and electrically connected to the head-mounted device's electrical module. The angle between the first and second directions is less than or equal to 90°, making it easier to adapt to square or curved frames. The extension direction of the second circuit board 320 also allows it to hang on the frame, thereby reducing the risk of the near-eye display module 200 and the first electrical connector 310 falling.

[0050] The first circuit board 300 and the second circuit board 320 include a housing and wires, wherein the wires are wrapped by the housing, wherein the housing and the wires are both flexible structures. The flexible structure facilitates the first circuit board 300 and the second circuit board 320 to adhere to the surface of the frame.

[0051] The first electrical connection socket 310 and the second electrical connection socket 330 are configured to bend relative to the first circuit board 300. According to the shape of the head mounted device, the first electrical connection socket 310 and the second electrical connection socket 330 are bent at corresponding angles relative to the first circuit board 300 to complete the assembly.

[0052] like Figure 4 and Figure 5 As shown, the near-eye display module 200 includes a first housing 230, a micro display module 210 and an optical module 220, which are located inside the first housing 230. When in use, the image played by the micro display module 210 is illuminated into the human eye through the optical module 220.

[0053] The micro-display module 210 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; the optical module 220 includes a lens, etc. In some embodiments, the optical module can adopt the technical solution of the Chinese patent application number 2023224964840. Of course, other optical modules that can realize near-eye display technology are also feasible.

[0054] like Figure 6 As shown, the first electrical connection seat 310 includes a second shell 311 and a connecting circuit board 312 located in the second shell 311, the micro display module 210 and the connecting circuit board 312 are electrically connected by the second circuit board 320, and the optical module 220 is located on the light-emitting side of the micro display module 210 and away from the gap 201.

[0055] The second housing 311 may include a storage space, and the first circuit board 300 is configured to allow at least partial retraction and storage within the storage space of the second housing 311. The first circuit board 300 is relatively long to accommodate different head-mounted devices. Because the distance between the first and second positions may vary on different head-mounted devices, during assembly, the exposed length of the first circuit board 300 can be adjusted by adjusting the distance between the first and second positions. The excess portion of the first circuit board 300 is stored in the storage space, maintaining a straight, flat position and enhancing the overall aesthetics. In some embodiments, the first circuit board 300 is provided with an adsorption layer. The adsorption layer may include an adhesive layer, such as Velcro, adhesive, or a magnetic sheet. In this case, the main body 100 may be made of metal, and the adsorption layer is configured to conform to the surface of the main body 100. For example, the main body 100 may have a flat or curved surface. The adsorption layer ensures that the extended surface of the first circuit board 300 conforms to the surface of the main body 100, effectively preventing the first circuit board 300 from being too obtrusive.

[0056] The near-eye display module 200 and / or the first electrical connection socket 310 further includes a magnet, which is located on a side of the corresponding shell facing the gap 201 , and is configured to be magnetically attracted to be fixed on the head-mounted device.

[0057] In this embodiment, both the near-eye display module 200 and the first electrical connection base 310 include magnets. Specifically, a magnet is provided on the side of the first housing 230 facing the gap 201 , and a magnet is provided on the side of the second housing 311 facing the gap 201 .

[0058] In some embodiments, the first electrical connection socket 310 of the near-eye display device also includes a camera module, which is located in the second shell 311. The camera module is electrically connected to the first circuit board 300. The camera module faces away from the near-eye display module 200 and is configured to obtain external environmental information.

[0059] like Figure 1 As shown, the second electrical connection base 330 is bent relative to the first circuit board 300 in the first direction.

[0060] like Figure 7 As shown, the second electrical connection seat 330 includes a third shell 331 and an electrical contact 332 provided on the third shell 331, the electrical contact is electrically connected to the first circuit board 300, and the third shell 331 is configured to be releasably connected to the second position of the head-mounted device.

[0061] In this embodiment, the first position and the second position are located on different sides of the head mounted device.

[0062] In other embodiments, the first position and the second position may be located on the same side of the head mounted device.

[0063] In this embodiment, a head-mounted device is also proposed.

[0064] Reference Figure 2 and Figure 3 ,as well as Figures 8-12 , the structure of the head-mounted device is described accordingly. For the convenience of description, in this embodiment, the head-mounted device is taken as an example of glasses. It should be noted that in other embodiments, the head-mounted device can also be a helmet, etc.

[0065] Two near-eye display devices can be installed on the head-mounted device, corresponding to the user's left eye and right eye respectively.

[0066] The head-mounted device includes a main body 100, an electrical module and the near-eye display device mentioned above.

[0067] The main body 100 has a near-eye end surface 101 and a far-eye end surface 102, which are located on either side of the main body 100. The near-eye end surface 101 faces the human eye side 1011 of the main body 100. When the head-mounted device is in the worn state, the near-eye end surface 101 faces the human eye side 1011 of the main body 100, and the far-eye end surface 102 faces the environment side 1021. The human eye side 1011 is the side where the user's eyes are located.

[0068] The electrical module is disposed in the main body 100 .

[0069] The near-eye display device includes a near-eye display module 200, a first electrical connection socket 310, and a second electrical connection socket 330. The near-eye display module 200 and the first electrical connection socket 310 are configured to be releasably connected to a first position of the main body 100 through a gap 201. The near-eye display module 200 is further configured to be movably disposed on the near-eye end surface 101, and the first electrical connection socket 310 is further configured to be movably disposed on the far-eye end surface 102. Because the near-eye display module 200 and the first electrical connection socket 310 are movable relative to the main body 100, the user can adjust the position of the near-eye display module 200 and the first electrical connection socket 310 on the main body 100 according to the position of their own eyeballs.

[0070] The second electrical connection socket 330 is configured to be releasably connected to a second position of the main body 100 away from the first position. The second position is relatively fixed, and the second electrical connection socket 330 is electrically connected to the electrical module of the head-mounted device.

[0071] In this embodiment, the head-mounted device also includes a magnetic component, which is located on the main body 100 facing the near-eye end face 101, and / or the magnetic component is located on the main body 100 facing the far-eye end face 102, wherein the magnetic component is configured to attract each other with the near-eye display module 200 and / or the first electrical connection seat 310.

[0072] The magnetic element extends along the length of the main body 100 , thereby allowing the near-eye display module 200 and the first electrical connection socket 310 to move along the length of the main body 100 . Figures 8-11 , the direction indicated by arrow a is parallel to the length direction of the main body 100.

[0073] The near-eye display module 200 and the first electrical connection socket 310 are configured to be movable along the length direction of the near-eye end surface 101, and the length direction is parallel to the second direction. The head-mounted device further includes a lens 111, which is arranged on the main body 100. Figure 10 The first circuit board 300 of the near-eye display device does not overlap with the lens 111 in the first direction, thereby preventing the first circuit board 300 from blocking the lens 111. The length of the near-eye end surface 101 is consistent with the length direction of the main body 100.

[0074] like Figure 2 and Figure 3 As shown, the head-mounted device further includes temples 131 , and a bracket 130 is provided at the end of the main body 100 in the length direction, and the temples 131 are connected to the bracket 130 .

[0075] The electrical module includes a battery and an electrical connection portion 132, and the battery and the electrical connection portion 132 are electrically connected. Figure 12 As shown, the electrical connection portion 132 is provided at a second position on the bracket 130. Since the battery is installed inside the head mounted device, the battery is not shown in the drawings.

[0076] The second electrical connection base 330 is electrically connected to the electrical connection portion 132. The electrical connection portion 132 may include electrical contacts or contact pins, and may also include an interface such as USB, TYPE-C, etc.

[0077] The temple 131 is rotatably connected to the bracket 130 , and the second position is located on a side surface of the main body 100 that is different from the distal end surface 102 .

[0078] The electrical connection portion 132 includes a first electrical contact that is adapted to the second electrical connection socket 330 , so that the electrical connection portion 132 and the second electrical connection socket 330 are electrically connected via the first electrical contact.

[0079] In some embodiments, the battery is located on the bracket 130 .

[0080] In some other embodiments, the battery is located in the temple 131, and the end surfaces of the temple 131 and the bracket 130 that rotate with each other are respectively provided with second electrical contacts, thereby making the electrical connection portion 132 electrically connected to the battery through the second electrical contacts.
