[0045] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be specifically noted that the following embodiments are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only partial embodiments of the present application rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0046] The mention of "embodiment" in the present application means that the specific features, structures, or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0047] The present application describes a near-eye display device. The near-eye display device may be an augmented reality or virtual reality device, such as augmented reality or virtual reality glasses. Of course, the near-eye display device may also be other devices that need to be worn on the head, such as glasses, such as devices with other functions such as lighting and wearable on the head, which will not be elaborated here. The following will be described in detail by taking augmented reality or virtual reality glasses as an example.

[0048] In an example of augmented reality or virtual reality glasses, a near-eye display device can be configured to transfer data to and receive data from an external processing device via a signal connection, which can be a wired connection, a wireless connection, or a combination thereof. However, in other scenarios, the near-eye display device can be used as a stand-alone device, i.e., data processing is performed within the near-eye display device itself. The signal connection can be configured to carry any kind of data, such as image data (e.g., still images and / or full-motion video, including 2D and 3D images), audio, multimedia, voice, and / or any other type of data. The external processing device can be, for example, a game console, a personal computer, a tablet computer, a smart phone, or other types of processing devices. The signal connection can be, for example, a Universal Serial Bus (USB) connection, a Wi-Fi connection, a Bluetooth or Bluetooth Low Energy (BLE) connection, an Ethernet connection, a cable connection, a DSL connection, a cellular connection (e.g., 3G, LTE / 4G, or 5G), etc., or a combination thereof. Additionally, the external processing device can communicate with one or more other external processing devices via a network, which can be or include, for example, a Local Area Network (LAN), a Wide Area Network (WAN), an intranet, a Metropolitan Area Network (MAN), the global Internet, or a combination thereof.

[0049] A display component, optics, sensors, a processor, etc. can be installed in the near-eye display device. In an example of augmented reality or virtual reality glasses, the display component is designed to, for example, implement the function of virtual reality glasses by projecting light into the user's eyes, or implement the function of augmented reality glasses by projecting light into the user's eyes and overlaying an image on the user's view of their real-world environment. The near-eye display device can also include an ambient light sensor and can also include an electronic circuitry system to control at least some of the above components and perform associated data processing functions. The electronic circuitry system can include, for example, one or more processors and one or more memories.

[0050] Please refer to Figures 1 to 3 , Figure 1 is a schematic structural diagram of the near-eye display device 10 provided by an embodiment of the present application. Figure 2 is Figure 1 a schematic connection structure diagram of the display module 100, the device body 200, and the strap 300 in Figure 3 is Figure 2 another schematic connection structure diagram of the display module 100, the device body 200, and the strap 300 in

[0051] The near-eye display device 10 can implement the function of a virtual reality or augmented reality environment in front of the user's eyes. As Figures 1 to 3As shown in the figure, the near-eye display device 10 may include: a display module 100, a device body 200, a strap 300, and a wearing bracket 400. The display module 100 may be connected to one end of the device body 200 and may present a virtual reality or augmented reality environment under the control of the device body 200. The device body 200 may be detachably connected to the wearing bracket 400, so that the user can wear the display module 100 in front of the user's eyes through the wearing bracket 400 for use. At the same time, when the device body 200 is detached from the wearing bracket 400, the device body 200 can also be bent in the direction close to the display module 100. The strap 300 may be connected to the other end of the device body 200, and it can be used to detachably connect to the display module 100 after the device body 200 is bent, so that the display module 100, the device body 200, and the strap 300 can form a ring structure, thereby enclosing and forming a wearing space A.

[0052] In this way, the user can wear the display module 100 and the device body 200 on the wrist like a watch through the wearing space A for carrying, while the wearing bracket 400 can be worn on the user's head like glasses for carrying, so as to improve the portability of the near-eye display device 10. Of course, when the display module 100 and the device body 200 are worn on the user's wrist, they can also implement all functions or part of the functions, so that the display module 100 and the device body 200 can also be used like a smart watch. Compared with the solution that can only be worn on the user's head for use, the near-eye display device 10 provided in this embodiment can not only improve the portability of the near-eye display device 10, but also expand the usage methods and usage scenarios of the near-eye display device 10.

[0053] Refer to Figures 4 to 6 , Figure 4 is Figure 2 the schematic diagram of the connection structure of the display module 100 with the device body 200 and the wearing bracket 400 when the display module 100 is in the first position in Figure 5 is Figure 2 the schematic diagram of the connection structure of the display module 100 with the device body 200 and the wearing bracket 400 when the display module 100 is in the second position in Figure 6 is Figure 2 the schematic diagram of the structure of the display module 100 in

[0054] The display module 100 can be fixed in front of the user's eyes through the wearing bracket 400, and the display module 100 can also be rotatably connected to the device body 200, so that when the display module 100 rotates to the first position, it can be used to implement the functions of a virtual reality or augmented reality environment, and when it rotates to the second position, it can be used to jointly enclose and form the wearing space A with the device body 200 and the strap 300. As Figures 4 to 5As shown, when the display module 100 and the device body 200 are worn on the user's head through the wearing bracket 400, the display module 100 located at the first position can be disposed opposite to the user's eyes, and the display module 100 located at the second position can be symmetrically disposed with respect to the device body 200 with the display module 100 located at the first position.

[0055] In this way, when the user rotates the display module 100 to the second position to jointly enclose a wearing space A with the device body 200 and the strap 300, the device body 200 can be bent in a direction away from the wearing bracket 400 and towards the display module 100. After the device body 200 is bent to jointly enclose the wearing space A with the strap 300 and the display module 100, the side of the device body 200 connected to the wearing bracket 400 can be disposed away from the wearing space A, so as to expose the detachable components, electrical connectors, speaker holes, etc. provided on the side of the device body 200 connected to the wearing bracket 400 on the side away from the wearing space A, that is, the side of the user's wrist, reducing the probability that the sweat generated by the user during long-term wearing affects the near-eye display device 10 through the foregoing components or holes. Among them, the display module 100 is specifically rotated about the first direction X as the axis direction, and the first direction X can be parallel to the length direction of the device body 200 in the flattened state.

[0056] In addition, the foregoing descriptions of the first position and the second position are only one of the solutions that can be adopted in this embodiment, and the first position and the second position are not limited thereto. For example, the display module 100 at the second position can also be reached after the display module 100 at the first position is rotated by 90°, and it will not be symmetrically disposed with respect to the device body 200 with the display module 100 at the first position. Of course, with the change of the second position, the bending direction of the device body 200 will also change accordingly, as long as the device body 200 can be bent to jointly enclose a wearing space A with the display module 100 and the strap 300.

[0057] As Figure 6 shown, the display module 100 may include: an optical lens 110 and a frame 120. The optical lens 110 can be disposed on the frame 120, and it can present the function of a virtual reality or augmented reality environment under the control of the device body 200. The frame 120 can be connected to the device body 200, so that the optical lens 110 can be fixed on the wearing bracket 400 through the device body 200 for use. At the same time, the frame 120 can also rotate relative to the device body 200, so that the display module 100 can realize the function of a virtual reality or augmented reality environment when rotated to the first position, and jointly enclose a wearing space A with the device body 200 when rotated to the second position.

[0058] The optical lens 110 can be disposed on one side of the frame 120 facing away from the device body 200 and is disposed opposite to the device body 200, and it can function in a virtual reality or augmented reality environment under the control of the device body 200. For example, the optical lens 110 can be a waveguide sheet, specifically a planar grating waveguide such as a diffraction grating waveguide, so that the near-eye display device 10 can present a virtual reality / augmented reality environment through the optical lens 110. Among them, the optical lens 110 can be provided with a light coupling inlet portion and a light coupling outlet portion. The light coupling inlet portion can be disposed opposite to the device body 200, the light coupling outlet portion can be connected to the light coupling inlet portion, and the two can jointly form an optical path of the optical lens 110. At the same time, when the user wears the near-eye display device 10 on the head, the light coupling outlet portion can also be disposed opposite to the user's eyes. In this way, the light emitted by the device body 200 can be coupled into the optical lens 110 from the light coupling inlet portion, transmitted in the optical path, and finally the light will be coupled out of the optical lens 110 at the light coupling outlet portion, enter the wearer's eyes and form an image on the retina, thereby realizing the virtual reality or augmented reality function of the near-eye display device 10. The above is only a simple description of the basic functions of the waveguide sheet. The specific optical principles and structures of the waveguide sheet can refer to the prior art, and will not be elaborated in this embodiment.

[0059] Please refer to Figures 7 to 10 , Figure 7 is Figure 4 a schematic structural diagram of the frame 120 in Figure 8 is Figure 7 a partial enlarged view of the K position in Figure 9 is Figure 7 a partial cross-sectional structural diagram of the frame 120 along VI-VI in Figure 10 is Figure 2 a partial cross-sectional structural diagram of the display module 100 and the device body 200 along V-V in

[0060] The frame 120 can be used to mount the optical lens 110, so that the optical lens 110 can be rotatably connected to the device body 200 through the frame 120. As Figure 7 shown, the frame 120 can be provided with a frame portion 121 and a bearing portion 122. The frame portion 121 can be square in shape, and the frame portion 121 can also enclose an installation space B for mounting the optical lens 110. The bearing portion 122 can be disposed in the installation space B, and the bearing portion 122 can not only be used to bear the optical lens 110 to improve the assembly convenience of the optical lens 110 and the frame 120, but also be used to rotatably connect to the device body 200, so that the frame 120 can be rotated to the first position or the second position.

[0061] On the side of the frame part 121 facing away from the installation space B, there is also a positioning post 1211, and the positioning post 1211 can be arranged away from the device main body 200, and it can be used for detachably connecting with the strap 300, so as to facilitate the frame 120, the device main body 200 and the strap 300 to jointly enclose a wearing space A. As Figure 8 shown, on the side of the frame part 121 facing away from the installation space B, there may be an avoidance groove 1201, the positioning post 1211 may be arranged in the avoidance groove 1201, and the positioning post 1211 may be T-shaped in appearance. Among them, when the strap 300 is connected to the frame 120, the positioning post 1211 can be inserted into the strap 300 and engaged with the strap 300. When the strap 300 is detached from the frame 120, the strap 300 can undergo elastic deformation to provide an avoidance space for the positioning post 1211 to withdraw from the strap 300. In this way, when the user needs to carry the display module 100 and the device main body 200, the positioning post 1211 can be connected to the strap 300 after the device main body 200 is bent, so that the display module 100, the device main body 200 and the strap 300 jointly enclose a wearing space A. When the user needs to assemble the display module 100 and the device main body 200 onto the wearing bracket 400, the positioning post 1211 and the strap 300 can be detached, so that the device main body 200 can be restored to the flattened state before bending, so as to facilitate the assembly of the device main body 200 and the wearing bracket 400.

[0062] In some embodiments, the frame 120 and the strap 300 can also be assembled by other detachable connection methods, as long as the detachable connection between the frame 120 and the strap 300 can be realized. For example, the frame 120 and the strap 300 can also be assembled by some common detachable connection methods between the watchband and the watch head in watches, such as spring bars, watchband buckles and metal buckles, etc. Or, the frame 120 can be provided with threaded holes, and the strap 300 can be provided with screws, and the strap 300 can be detachably connected to the frame 120 by screwing the screws into the threaded holes. Of course, in addition to realizing detachable connection through mechanical structures, detachable connection between the strap 300 and the frame 120 can also be realized by means such as magnetic attraction, and this embodiment does not limit this.

[0063] The side of the bearing part 122 facing away from the device main body 200 can be used to place the optical lens 110, so that the optical lens 110 can be fixed in the installation space B through the bearing part 122. For example, glue can be provided on one side of the bearing part 122 to bond the optical lens 110 and the bearing part 122. Of course, in order to improve the assembly firmness of the optical lens 110 and the frame 120, the optical lens 110 and the frame part 121 can also be dot-glued and cured to bond the optical lens 110 and the frame part 121. As Figure 7 and Figure 9As shown, the bearing portion 122 may also be provided with a light-transmitting hole 1221, and the light-transmitting hole 1221 may communicate the optical lens 110 and the device main body 200, so that the light emitted by the device main body 200 can be irradiated onto the optical lens 110 through the light-transmitting hole 1221. In some embodiments, in addition to the way of opening the light-transmitting hole 1221, the bearing portion 122 may also be designed with partial transparency or full transparency, so that the light emitted by the device main body 200 can be irradiated onto the optical lens 110, and only the light transmittance required for the near-eye display device 10 to achieve virtual reality or augmented reality needs to be satisfied.

[0064] On one side of the bearing portion 122 close to the device main body 200, an annular flange 1222 may be provided, and the annular flange 1222 may protrude outside the installation space B, and it may be used for rotatably connecting with the device main body 200. As Figures 9 to 10 shown, the annular flange 1222 may be arranged around the light-transmitting hole 1221, and the annular flange 1222 may also enclose a connection space C communicating with the light-transmitting hole 1221. The connection space C may be used to accommodate the corresponding mating parts on the device main body 200, so as to facilitate the rotational connection between the annular flange 1222 and the device main body 200. Among them, an annular card slot 12221 may be provided on one side of the annular flange 1222 located in the connection space C. The mating parts on the device main body 200 may be arranged in the annular card slot 12221 and may be clamped with the inner side wall of the annular card slot 12221 in the first direction X to prevent the device main body 200 from disengaging from the connection space C and improve the reliability of the rotational connection between the frame 120 and the device main body 200. At the same time, a part of the annular card slot 12221 may also communicate with the installation space B to provide an avoidance space for the rotation of the mating parts of the device main body 200 and prevent the mating parts of the device main body 200 from interfering with the frame 120 during rotation. Of course, if the annular card slot 12221 has enough space, the annular card slot 12221 may not communicate with the installation space B.

[0065] Please refer to Figure 3 for reference Figures 11 to 12 , Figure 11 which is Figure 2 the schematic structural diagram of the device main body 200 in Figure 12 and Figure 11 is the exploded structural diagram of the device main body 200 in

[0066] One end of the device main body 200 may be connected to the frame 120, and the device main body 200 may also be bent in a direction close to the frame 120 in the flattened state, so that the device main body 200, the display module 100 and the strap 300 can jointly enclose a wearing space A. As Figures 11 to 12As shown, the device main body 200 may be provided with a plurality of housings 210, a flattening assembly 220, and electronic devices 230. The plurality of housings 210 may be connected in sequence, and one of two adjacent housings 210 may rotate in a direction close to or away from the other, so that the device main body 200 can be bent in a direction close to the display module 100. The flattening assembly 220 may be disposed on the housing 210, and may be used to provide a force to limit the rotation between two adjacent housings 210, that is, to limit the bending of the device main body 200 to maintain the flattened state of the device main body 200. The electronic devices 230 may be disposed in the housing 210, and may be used to implement the functions required by the near-eye display device 10.

[0067] The flattened state of the foregoing device main body 200 may be a state in which the sides of the plurality of housings 210 facing away from the wearing bracket 400 are flush in the first direction X, that is, the plurality of housings 210 are arranged in a "one" shape in the first direction X. In some embodiments, the flattened state of the device main body 200 may also be designed according to requirements. Not only do the plurality of housings 210 need to be completely flush, but the plurality of housings 210 may also be arranged and connected in an arc shape. It is only necessary that after the device main body 200 is detached from the wearing bracket 400, it can be bent and jointly enclose a wearing space A with the display module 100 and the strap 300.

[0068] The number of the housings 210 may be four, and the four housings 210 may be a first housing 211, a second housing 212, a third housing 213, and a fourth housing 214 respectively. As Figure 3 and Figure 11 shown, the first housing 211, the second housing 212, the third housing 213, and the fourth housing 214 may be connected in sequence. Among them, the first housing 211 may be located at one end of the device main body 200, and may be used to rotatably connect to the frame 120. The fourth housing 214 may be located at the other end of the device main body 200, and may be used to connect to the strap 300. At the same time, one of two adjacent housings 210 among the four housings 210 may rotate in a direction close to or away from the other, that is, the second housing 212 may rotate in a direction close to or away from the first housing 211, the third housing 213 may rotate in a direction close to or away from the second housing 212, and the fourth housing 214 may rotate in a direction close to or away from the third housing 213.

[0069] In this way, by rotating between the four housings 210, the device body 200 can be bent in the direction close to the display module 100. The strap 300 can then be displaced in the direction close to the frame 120 after the device body 200 is bent, and then detachably connected to the frame 120, so that the display module 100, the device body 200, and the strap 300 jointly enclose to form a wearing space A. Of course, in some embodiments, the number of the housings 210 may not be limited to four, and the number can be selected according to the electronic devices 230 to be installed and the designed length of the device body 200, such as two, three, five or more. This embodiment does not limit this. It should be noted that the above-mentioned "housing", "first housing", "second housing", "third housing" and "fourth housing" can be converted into each other. For example, the "first housing" can also be referred to as the "second housing" or the "housing".

[0070] Please refer to Figures 9 to 10 for reference Figures 13 to 14 , Figure 13 which Figure 11 is the assembly schematic diagram of the first housing 211 in Figure 14 and Figure 13 is the partial enlarged view of the L position in Figure 15 and Figure 10 is the partial cross-sectional structure schematic diagram of the frame 120 and the first housing 211 in another embodiment in Figure 16 and Figure 10 is the partial cross-sectional structure schematic diagram of the frame 120 and the first housing 211 in yet another embodiment in

[0071] The first housing 211 can be located at one end of the device body 200. One side of it can be used for rotatably connecting with the frame 120, and the other opposite side can be used for rotatably connecting with the second housing 212. As Figure 13 shown, the first housing 211 can be provided with a first cover body 2111 and a first box body 2112. The first cover body 2111 can cover the first box body 2112 and jointly enclose to form an accommodation space D to install the electronic device 230 by using the accommodation space D. Among them, the first cover body 2111 can be used for rotatably connecting with the frame 120 so that the frame 120 can rotate relative to the first housing 211. The first box body 2112 can be used for rotatably connecting with the second housing 212 so that the second housing 212 can rotate in the direction close to or away from the first housing 211.

[0072] One side of the first cover body 2111 can be provided with a connected annular retaining wall 2113 and a buckle 2114. As Figure 9 , Figure 10 and Figure 14As shown, the annular retaining wall 2113 can be disposed within the connection space C, that is, the annular flange 1222 can be sleeved on the annular retaining wall 2113, and the annular flange 1222 and the annular retaining wall 2113 can rotate relative to each other about the axial direction of the first direction X to achieve the rotation of the frame 120 relative to the first housing 211. At the same time, in order to reduce the friction between the annular retaining wall 2113 and the annular flange 1222, the first housing 211 can also be provided with a rotating ring 2115, and the rotating ring 2115 can be disposed between the annular retaining wall 2113 and the annular flange 1222 and sleeved on the annular retaining wall 2113. Among them, the rotating ring 2115 can separate the annular retaining wall 2113 and the annular flange 1222 to reduce the contact area between the annular retaining wall 2113 and the annular flange 1222. When the frame 120 rotates between the first position and the second position, the annular flange 1222 can rotate relative to the annular retaining wall 2113 through the rotating ring 2115.

[0073] In order to prevent the rotating ring 2115 from being displaced in the first direction X due to the rotation of the frame 120, the annular retaining wall 2113 can also be provided with a first limiting groove 21131, and the annular flange 1222 can be disposed in the second limiting groove 12222. The inner side of the rotating ring 2115 can be disposed within the first limiting groove 21131 and in contact with the inner wall of the first limiting groove 21131, while the outer side can be disposed within the second limiting groove 12222 and in contact with the inner wall of the second limiting groove 12222. In this way, the first limiting groove 21131 and the second limiting groove 12222 can limit the displacement of the rotating ring 2115 in the first direction X. Among them, the material of the rotating ring 2115 can be metal, and the rotating ring 2115 can also be provided with a notch to disconnect a part of the rotating ring 2115, and its shape can be similar to a "C" - shaped structure in appearance. Compared with a complete circular structure, when the rotating ring 2115 is assembled with the annular retaining wall 2113 and the annular flange 1222, the deformed amount of the disconnected rotating ring 2115 is higher, which can provide sufficient avoidance space for the assembly of the three, so as to facilitate the assembly of the three.

[0074] The buckle 2114 can be located on the side of the annular retaining wall 2113 away from the first cover body 2111, and the buckle 2114 can also be arranged in the annular slot 12221 and can be engaged with the inner side wall of the annular slot 12221 in the first direction X. Among them, the buckle 2114 can have a certain elastic deformation ability, so that when the buckle 2114 is inserted into the connection space C along with the annular retaining wall 2113, it can abut against the side of the annular flange 1222 located in the connection space C and undergo elastic deformation to provide a clearance space for the insertion of the annular retaining wall 2113. When the annular retaining wall 2113 is inserted in place, the buckle 2114 can be reset into the annular slot 12221 under the action of elastic force and engaged with the inner side wall of the annular slot 12221 to prevent the annular retaining wall 2113 from disengaging from the connection space C. In this embodiment, the number of buckles 2114 can be two, and the two buckles 2114 can be symmetrically arranged with respect to the first direction X. In some embodiments, the number of buckles 2114 can also be set according to requirements, and this embodiment does not limit this.

[0075] In order to enable the light emitted by the device body 200 to be transmitted to the optical lens 110 through the first housing 211, the first cover body 2111 can also be provided with a first notch 21111, and the first box body 2112 can be provided with a second notch 21121. As Figure 13 shown, when the first cover body 2111 and the first box body 2112 are assembled, the first notch 21111 and the second notch 21121 can jointly form a complete circular hole, and the annular retaining wall 2113 can also be arranged around the circular hole, so that the light emitted by the electronic device 230 in the accommodation space D can be irradiated onto the optical lens 110 through the circular hole and the light-transmitting hole 1221 on the frame 120. In some embodiments, only a part of the annular retaining wall 2113 can be arranged on the first cover body 2111, and the other part can be arranged on the first box body 2112, as long as the two parts can jointly form a complete annular retaining wall 2113 when the first cover body 2111 and the first box body 2112 are assembled. Or, the annular retaining wall 2113 can also be directly arranged on the first box body 2112.

[0076] In some embodiments, the positions of the annular ridge 1222 and the annular retaining wall 2113 can also be interchanged. That is, the annular ridge 1222 can be set on the first cover body 2111, and the annular retaining wall 2113 can be set on the frame 120. Correspondingly, the positions of the buckle 2114 and the annular groove 12221 can also be changed accordingly. In this way, the rotation connection between the frame 120 and the first shell 211 can still be achieved. In some embodiments, the positions of the buckle 2114 and the annular groove 12221 can also be interchanged. That is, the side of the annular ridge 1222 away from the bearing portion 122 can be provided with the buckle 2114, and the side of the annular retaining wall 2113 close to the annular ridge 1222 can be provided with the annular groove 12221. In this way, when the annular protrusion 1222 is sleeved on the annular retaining wall 2113 , the buckle 2114 can still be disposed in the annular groove 12221 , thereby realizing the rotational connection between the frame 120 and the first shell 211 .

[0077] Please combine Figure 10 See also Figures 15 to 16 , Figure 15 yes Figure 7 A schematic diagram of a partial cross-sectional structure of the middle frame 120 along VI-VI in another embodiment, Figure 16 yes Figure 10 Schematic diagram of the cooperation between the middle annular protrusion 1222 and the annular retaining wall 2113 in another embodiment.

[0078] In order to achieve the stationing of the frame 120 at the first position or the second position, the frame 120 is prevented from rotating relative to the first housing 211 due to the influence of gravity. The inner side wall of the annular groove 12221 may also have an inclined surface 12223. Figure 10 and Figure 15As shown, the inclined surface 12223 can be arranged on the inner side wall where the annular groove 12221 and the buckle 2114 are engaged. When the frame 120 rotates relative to the device body 200, the buckle 2114 will also slide along the inner side wall in the annular groove 12221, and will move along the inclined surface 12223 in the direction close to the optical lens 110 during the sliding process. At the same time, since the amount of movement between the frame 120 and the device body 200 is limited, the buckle 2114 will abut against the inclined surface 12223, that is, the inner side wall of the annular groove 12221 in the first direction X during the rotation process, so as to increase the friction between the frame 120 and the device body 200, thereby limiting the rotation of the frame 120. Of course, in order to realize the rotation of the frame 120 between the first position and the second position, the abutment force generated by the buckle 2114 and the inclined surface 12223 can be overcome. That is, the frame 120 and the device body 200 can be pre-designed with a certain amount of activity or deformation, so that the frame 120 and the device body 200 can be displaced to a certain extent in the first direction X after assembly, so as to avoid the problem of excessive abutment force between the frame 120 and the device body 200 causing them to be stuck and unable to rotate.

[0079] Specifically, the abutment force value between the frame 120 and the buckle 2114 can change in a hump curve. When the frame 120 is in the first position or the second position, the abutment force value between the frame 120 and the buckle 2114 can be at the trough position. As the frame 120 rotates, the abutment force value between the frame 120 and the buckle 2114 will gradually increase until it reaches the crest position, and finally falls back from the crest to the trough. For example, if the frame 120 needs to rotate 180° from the first position to the second position, then in the process of the frame 120 rotating from 0° to 90°, the abutment force between it and the buckle 2114 will gradually increase, and reach the maximum when it rotates to 90°, thereby limiting the rotation of the frame 120 and achieving the retention of the frame 120 in the first position. During the process of rotating the frame 120 from 90° to 180°, the contact force between the frame 120 and the buckle 2114 will gradually decrease and reach the minimum when rotating to 180°, so that the frame 120 can rotate to the second position for residence. In this way, the frame 120 and the buckle 2114 can cycle by rotating 180° each time to achieve the residence of the frame 120 in the first position and the second position, thereby reducing the probability of the frame 120 rotating due to other forces other than the user's manipulation.

[0080] It should be noted that the aforementioned situation that when the frame 120 is in the first position or the second position, the abutment force value between the frame 120 and the buckle 2114 can be at the position of the trough is only one of the schemes that can be adopted. For example, when the frame 120 is in the first position or the second position, the abutment force value between the frame 120 and the buckle 2114 can also be at the position of the crest, but not limited to the trough. The specific setting method can be adjusted according to the design requirements, and the present embodiment does not limit this. At the same time, the numerical limit of the aforementioned rotation angle is also only one of the schemes that can be adopted. For example, the frame 120 can also rotate from the first position to the second position by only 90°, 100° or 120°, but not limited to 180°. The specific rotation angle can also be set according to the requirements, and the present embodiment does not limit this.

[0081] In some embodiments, in addition to limiting the rotation of the frame 120 by setting the inclined surface 12223, the rotation of the frame 120 can also be limited by setting a damping member to achieve the retention of the frame 120 in the first position and the second position. Figure 16 As shown, a first damping member 1222a may be provided on one side of the annular ridge 1222 close to the annular retaining wall 2113, and a second damping member 2113a may be provided on one side of the annular retaining wall 2113 close to the annular ridge 1222, and the first damping member 1222a and the second damping member 2113a may be meshed with each other. The first damping member 1222a and the second damping member 2113a may be made of a material with a certain deformation ability such as rubber, foam, and silica gel. In this way, when the frame 120 is in the first position or the second position, the first damping member 1222a and the second damping member 2113a may be in a meshing state. When the frame 120 rotates relative to the first shell 211, the first damping member 1222a and the second damping member 2113a may abut against each other to limit the rotation of the frame 120. Of course, the abutment force generated between the first damping member 1222a and the second damping member 2113a can also be overcome, that is, the first damping member 1222a and the second damping member 2113a can be elastically deformed to provide the avoidance space required for the frame 120 to rotate.

[0082] In some embodiments, the rotation of the frame 120 may also be limited by providing a convex bump, a silicone sleeve, or a stopper in the annular groove 12221. For example, the annular groove 12221 may be provided with a stopper, and when the frame 120 rotates 180°, the buckle 2114 may be engaged with the stopper, so that the frame 120 can only rotate 180° in the same direction, thereby staying at the first position or the second position.

[0083] See also Figure 17 , Figure 17 yes Figure 2Another schematic diagram of the connection structure between the frame 120 and the device body 200.

[0084] In some embodiments, in addition to being able to rotate relative to the device body 200 with the first direction X as the axis direction, the display module 100 can also rotate relative to the device body 200 with the second direction Y as the axis direction. As Figure 17 shown, the first cover 2111 can be provided with a shaft body 2111a, and the frame 120 can be sleeved on the shaft body 2111a, so that the frame 120 can rotate relative to the first housing 211 through the shaft body 2111a, thereby switching between the first position and the second position. At the same time, the frame 120 and the shaft body 2111a can also adopt the method of the damping member as described above to realize the residence of the frame 120 at the first position and the second position. Among them, the second direction Y can be perpendicular to the length direction of the device body 200 in the unfolded state, so that the display module 100 can have a flipping motion similar to that of a flip phone when rotating, so as to flip the display module 100 from the first position to the second position, or from the second position to the first position.

[0085] Please refer to Figure 13 for reference Figures 18 to 22 , Figure 18 which is Figure 13 the assembly schematic diagram of the first housing 211 from another perspective in Figure 19 which is Figure 18 the partial enlarged view at M in Figure 20 which is Figure 11 the assembly schematic diagram of the second housing 212 in Figure 21 which is Figure 20 the partial enlarged view at N in Figure 22 which is Figure 2 the partial cross-sectional structure schematic diagram of the device body 200 along V-V in

[0086] As Figure 13 and Figures 18 to 19 shown, a connecting portion 21122 can be provided on the side of the first box body 2112 facing away from the annular retaining wall 2113, and the connecting portion 21122 can be used for rotatably connecting with the second housing 212. At the same time, a first installation groove 21123 can also be provided on the side of the first box body 2112 facing away from the annular retaining wall 2113, and the first installation groove 21123 can be used for installing a part of the structure of the flattening assembly 220, so as to cooperate with another part of the structure of the flattening assembly 220 on the second housing 212 to limit the rotation between the first housing 211 and the second housing 212.

[0087] The second housing 212 can be rotatably connected to the first box body 2112 through the connecting portion 21122. As Figures 20 to 21As shown, the second housing 212 may also be provided with a second cover 2121 and a second box body 2122, and the second cover 2121 may also be covered on the second box body 2122 and jointly enclose another accommodation space D with the second box body 2122 to install the electronic device 230. Wherein, one side of the second box body 2122 may be provided with an accommodation groove 21221, and the accommodation groove 21221 may be used to accommodate the connecting portion 21122. At the same time, the second box body 2122 may also be provided with a rotating shaft 21222, and the rotating shaft 21222 may be arranged in the accommodation groove 21221 and connected to the inner side wall of the accommodation groove 21221. The rotating shaft 21222 may be used for rotatably connecting with the connecting portion 21122 to realize the rotation between the first housing 211 and the second housing 212.

[0088] As Figure 22 shown, after the connecting portion 21122 is assembled into the accommodation groove 21221, the rotating shaft 21222 may pass through the second box body 2122 and the connecting portion 21122, so that the connecting portion 21122 can rotate relative to the second box body 2122 through the rotating shaft 21222. Wherein, the rotating shaft 21222 may specifically be a screw, and the area where the rotating shaft 21222 contacts the second box body 2122 has a thread, so that the rotating shaft 21222 can be tightened on the second housing 212 through the thread. At the same time, the area where the rotating shaft 21222 contacts the connecting portion 21122 may have a smooth surface to facilitate the rotation of the connecting portion 21122 through the rotating shaft 21222. In some embodiments, the rotation mode between the first housing 211 and the second housing 212 may not be limited to using the rotating shaft 21222, and the specific rotation connection mode may also be selected according to actual needs, as long as the first housing 211 and the second housing 212 can rotate.

[0089] As Figure 21 shown, in order to cooperate with a part of the flattening assembly 220 on the first housing 211, the side of the second box body 2122 provided with the accommodation groove 21221 may also be provided with a second installation groove 21223, and the second installation groove 21223 may be used to install a part of the structure of the flattening assembly 220. Wherein, when the first housing 211 and the second housing 212 are in a flattened state, the second installation groove 21223 may be arranged opposite to the first installation groove 21123, so that a part of the flattening assembly 220 in the first installation groove 21123 and a part of the flattening assembly 220 in the second installation groove 21223 can cooperate to provide a force to maintain the flattened state of the first housing 211 and the second housing 212. When the first housing 211 and the second housing 212 need to rotate, the force of the flattening assembly 220 can be overcome to push the first housing 211 or the second housing 212 to rotate to realize the bending of the device main body 200.

[0090] Please combineFigure 19 and Figure 21 See also Figures 23 to 25 , Figure 23 yes Figure 11 A schematic diagram of a partial cross-sectional structure of the device body 200 along IV-IV, Figure 24 yes Figure 3 A partial enlarged view of the O in the middle. Figure 25 yes Figure 23 A schematic diagram of the cross-sectional structure of the flattening assembly 220 in another embodiment.

[0091] like Figure 19 , Figure 21 as well as Figures 23 to 24 As shown, the flattening assembly 220 may be provided with a first connecting member 221 and a second connecting member 222. The first connecting member 221 may be provided in the first mounting groove 21123, the second connecting member 222 may be provided in the second mounting groove 21223, and the first connecting member 221 and the second connecting member 222 may be magnetically connected to provide a magnetic force to limit the rotation between the first shell 211 and the second shell 212, thereby maintaining the flattened state of the two adjacent shells 210. When the device body 200 needs to be bent, the user may bend the first shell 211 or the second shell 212 to overcome the magnetic force generated by the first connecting member 221 and the second connecting member 222 to push the first shell 211 or the second shell 212 to rotate, thereby achieving the bending of the device body 200. When the strap 300 is disassembled from the frame 120, the first shell 211 and the second shell 212 can rotate under the magnetic force generated by the first connector 221 and the second connector 222, so that the first shell 211 and the second shell 212 can be flattened by magnetic force, thereby maintaining the flattened state of the two adjacent shells 210. Among them, both the first connector 221 and the second connector 222 can be magnets to increase the strength of the magnetic connection between the two. Of course, only one of the first connector 221 and the second connector 222 can be a magnet, and the other can be an object that can be attracted by magnetic force, such as metal.

[0092] In some embodiments, in addition to maintaining the flattened state of the first shell 211 and the second shell 212 by magnetic connection, the flattened state of the first shell 211 and the second shell 212 can also be maintained by deformation force. Figure 25As shown, the flattening assembly 220 can be provided with a guide member 223, a sliding member 224, and an elastic member 225. One end of the guide member 223 can be used to connect with the first box body 2112, and the guide member 223 can be arranged in an arc shape, and a guide space 2231 can be arranged therein. One end of the sliding member 224 can be used to connect with the second box body 2122, and the other end of the sliding member 224 can be arranged in the guide space 2231 and can slide along the guide member 223 in the guide space 2231. The elastic member 225 can be arranged in the guide space 2231, and the elastic member 225 can be respectively connected with the guide member 223 and the sliding member 224. When the sliding member 224 slides relative to the guide member 223, the elastic member 225 can be compressed or stretched under the drive of the sliding member 224, so as to generate a deformation acting force, so that the sliding member 224 can be reset by the deformation acting force after sliding.

[0093] In this way, when the first housing 211 and the second housing 212 are in a flattened state, the elastic member 225 can be in a state without deformation. When the first housing 211 and the second housing 212 are bent under force, so that the sliding member 224 slides along the guide member 223 in the guide space 2231, the elastic member 225 can undergo elastic deformation to provide a deformation acting force for maintaining the flattened state of the first housing 211 and the second housing 212. Of course, the deformation acting force generated by the elastic member 225 can also be overcome, so that the user can bend the first housing 211 and the second housing 212, and can use the strap 300 to connect with the frame 120 after the first housing 211 and the second housing 212 are bent, so as to maintain the bent state of the first housing 211 and the second housing 212. When the strap 300 is disassembled from the frame 120, the first housing 211 and the second housing 212 can be reset to the flattened state under the drive of the deformation acting force.

[0094] In addition, in order to prevent the sliding member 224 from disengaging from the guide space 2231, the flattening assembly 220 can also be provided with a corresponding limiting structure. For example, the flattening assembly 220 can also be provided with a pin, and the pin can be fixed on the guide member 223. Correspondingly, the sliding member 224 located in the guide space 2231 can be provided with a groove. In this way, the sliding of the sliding member 224 can be restricted by inserting the pin into the groove, so as to prevent the sliding member 224 from disengaging from the guide space 2231. The length of the groove is the sliding stroke of the sliding member 224.

[0095] The structures of the third housing 213 and the fourth housing 214 may be the same as that of the second housing 212. Also, the way the third housing 213 is rotatably connected to the second housing 212 and the way the fourth housing 214 is rotatably connected to the third housing 213 may be the same as the way the first housing 211 is rotatably connected to the second housing 212. Meanwhile, corresponding flattening assemblies 220 may be provided between the third housing 213 and the second housing 212, and between the fourth housing 214 and the third housing 213, for maintaining the flattened states of the second housing 212, the third housing 213, and the fourth housing 214. Specifically, for the structures and the rotational connection manners of the second housing 212 and the third housing 213, and the third housing 213 and the fourth housing 214, reference may be made to the first housing 211 and the second housing 212 in the foregoing embodiments, which will not be elaborated herein.

[0096] The electronic device 230 may be disposed within the housing 210 and may be used to implement the functions of the near-eye display device 10. As Figure 12 shown, the electronic device 230 may include: an optical engine 231, a main board 232, a battery 233, and a speaker 234. Among them, the optical engine 231 may be disposed within the accommodation space D of the first housing 211, and the light emitted therefrom may irradiate onto the optical lens 110 for imaging. The main board 232 may be disposed within the accommodation space D of the second housing 212. The battery 233 may be disposed within the accommodation space D of the third housing 213. The speaker 234 may be disposed within the accommodation space D of the fourth housing 214. Meanwhile, the optical engine 231, the main board 232, the battery 233, and the speaker 234 may also be electrically connected through a flexible circuit board. Of course, the electronic device 230 is not limited to including the foregoing devices. It may also include more devices that can be loaded in the near-eye display device 10, and the arrangement of each device is not limited to the foregoing manner. The specific layout manner may be adjusted according to design requirements, and this embodiment does not make any limitations thereto.

[0097] Please refer to Figure 2 and Figure 8 for reference. Figures 26 to 28 , Figure 26 which Figure 3 is a schematic structural view of the strap 300 in Figure 27 , Figure 11 and Figure 28 which Figure 2 is a partial enlarged view of the P position in

[0098] One end of the strap 300 may be connected to the fourth housing 214, and the other end of the strap 300 may also be detachably connected to the frame 120 after the device body 200 is bent, so that the display module 100, the device body 200, and the strap 300 jointly enclose to form a wearing space A. As Figures 26 to 27As shown, one end of the strap 300 can be rotatably connected to the fourth housing 214, enabling the strap 300 to rotate relative to the fourth housing 214 for facilitating the detachable connection between the strap 300 and the frame 120. For example, a spring pin 310 can be provided at one end of the strap 300, and the fourth housing 214 can be provided with a corresponding first assembly groove 2141, and the spring pin 310 can be disposed in the first assembly groove 2141, such that the strap 300 can not only be rotatably connected to the fourth housing 214 but also be detachably connected to the fourth housing 214. Thus, when the user wears the device body 200 on the head for use, the strap 300 can be detached for storage. Among them, the specific structure of the spring pin 310 can refer to the spring lug in the prior art and will not be elaborated here.

[0099] The other end of the strap 300 can be provided with positioning holes 320, and the number of the positioning holes 320 can be multiple. As Figure 8 and Figure 26 shown, the multiple positioning holes 320 can be arranged in sequence in the length direction of the strap 300, and they can be used for detachably connecting to the positioning posts 1211 on the frame 120. When the strap 300 is connected to the frame 120, the positioning posts 1211 can be inserted into the positioning holes 320 and snap-connected to the strap 300. Meanwhile, the user can select the corresponding positioning hole 320 for connection according to their own wrist size. When the strap 300 and the frame 120 are detached, the strap 300 can undergo elastic deformation to provide a clearance space for the positioning posts 1211 to withdraw from the positioning holes 320.

[0100] In addition, in order to accommodate the strap 300, after the strap 300 is detached from the frame 120, the other end of the strap 300 can also be detachably connected to the first housing 211, enabling the entire strap 300 to be attached to the device body 200. As Figure 2 、 Figure 26 and Figure 28 shown, a limiting post 21124 can be provided on the side of the first box body 2112 away from the first cover body 2111, and the limiting post 21124 can be inserted into the positioning hole 320 of the strap 300 and snap-connected to the strap 300. Correspondingly, the strap 300 can also undergo elastic deformation to provide a clearance space for the limiting post 21124 to withdraw from the positioning hole 320 to achieve the detachable connection between the first housing 211 and the other end of the strap 300. Thus, the device body 200 can be used to accommodate the strap 300, enabling the strap 300 to be attached to multiple housings 210. In this embodiment, the material of the strap 300 can be a flexible and skin-friendly material, such as soft glue, rubber, silica gel, hemp rope or corresponding composite materials, etc., to improve the wearing comfort of the user.

[0101] In some embodiments, when the number of the housings 210 is large enough such that the housing 210 at the end after the device body 200 is bent can be connected to the frame 120, the design of the strap 300 can also be cancelled. Meanwhile, the display module 100 and the device body 200 can also enclose to form a "C" - shaped structure, not limited to enclosing to form a complete annular structure. If the display module 100 and the device body 200 enclose to form a "C" - shaped structure, then the device body 200 can also be provided with components for restricting the rotation of two adjacent housings 210, so that the housings 210 can stay after rotation. Among them, the components for staying can refer to the designs of the first damping member 1222a and the second damping member 2113a in the foregoing embodiments, that is, one of the rotating shafts 21222 and the connecting portions 21122 is provided with the first damping member 1222a, and the other is provided with the second damping member 2113a, so that after the connecting portion 21122 rotates relative to the rotating shaft 21222, the damping force between the first damping member 1222a and the second damping member 2113a can be used to realize the staying of two adjacent housings 210 at different positions.

[0102] Please refer to Figures 29 to 31 , Figure 29 is Figure 2 a schematic connection structure diagram of the display module 100, the device body 200, and the strap 300 in another embodiment, Figure 30 is Figure 29 another schematic connection structure diagram of the display module 100, the device body 200, and the strap 300, Figure 31 is Figure 30 yet another schematic connection structure diagram of the display module 100, the device body 200, and the strap 300.

[0103] Since the length of the device body 200 is limited, the strap 300 is designed to connect the device body 200 and the display module 100. However, the longer strap 300 is not convenient for storage after being disassembled from the frame 120. And if the strap 300 is attached to the device body 200 for storage as in the foregoing embodiments, it will affect the functional design of the device body 200. For example, the side of the second box body 2122 facing away from the second cover body 2121 can be used to design a touch panel, so that the user can perform touch operations. And attaching the strap 300 to the device body 200 for storage will block the area for designing the touch panel, resulting in limited functional design of the device body 200.

[0104] To this end, in some embodiments, the device main body 200 can also be telescopic, and after being extended, it can be bent to form a wearing space A together with the display module 100 and the strap 300, so as to reduce the designed length of the strap 300 by extending the length of the device main body 200 and avoid the influence of the long strap 300 on the functional design of the device main body 200. As Figures 29 to 31 shown, in addition to the first housing 211, the second housing 212, the third housing 213, and the fourth housing 214 that are sequentially connected, the device main body 200 can also be provided with a bending member 250 and a limiting component 260. Among them, the bending member 250 can be used to realize the sliding of the first housing 211 and the second housing 212, so that the distance between the first housing 211 and the second housing 212 increases or decreases, thereby realizing the telescoping of the device main body 200. At the same time, the bending member 250 can also be used to bend when the distance between the first housing 211 and the housing 212 increases, that is, after the device main body 200 is extended, so as to realize the bending of the device main body 200. The limiting component 260 can be used to provide a force to limit the sliding of the first housing 211 and the second housing 212, that is, to limit the telescoping of the device main body 200, so as to maintain the flattened state of the device main body 200. In addition, the structures of the first housing 211, the second housing 212, the third housing 213, and the fourth housing 214 are the same as or similar to those in the foregoing embodiments, and the second housing 212, the third housing 213, and the fourth housing 214 can still be rotatably connected as in the foregoing embodiments and can maintain the flattened state under the action of the flattening component 220, which will not be elaborated here.

[0105] Please refer to Figures 32 to 35 , Figure 32 is Figure 30 the schematic structural diagram of the first box body 2112 in Figure 33 is Figure 30 the partial structural diagram of the bending member 350 in Figure 34 is Figure 30 the schematic connection structure diagram of the first box body 2112 and the partial bending member 350 in Figure 35 is Figure 30 the partial connection structure diagram of the first box body 2112, the second box body 2122, the bending member 250, and the limiting component 260 in

[0106] As Figures 32 to 34As shown in the figure, on opposite sides of the first box body 2112 located within the accommodation space D, a second assembly groove 21125 and a sliding groove 21126 that are connected and communicate with each other can be provided. Moreover, the extending directions of the second assembly groove 21125 and the sliding groove 21126 can be perpendicular to each other, such that the two can be arranged in an "L" shape. Among them, the second assembly groove 21125 can be used to provide an avoidance space for the installation of the bending member 250, so that one end of the bending member 250 can be installed into the sliding groove 21126 through the second assembly groove 21125. At the same time, in order to facilitate the connection between the bending member 250 and the second housing 212, an opening 21127 can also be provided on one side of the first box body 2112 close to the second housing 212, such that the other end of the bending member 250 can extend outside the accommodation space D through the opening 21127 and be slidably connected to the second housing 212. In addition, on opposite sides of the first box body 2112 where the second assembly groove 21125 and the sliding groove 21126 are provided, a fixing groove 21128 can also be provided, and this fixing groove 21128 can be used to install a part of the structure of the limiting component 260.

[0107] On opposite sides of the end part of the bending member 250, protrusions 251 can be provided, and these protrusions 251 can be installed into the sliding groove 21126 through the second assembly groove 21125 and can slide along the sliding groove 21126. Among them, after the protrusions 251 slide, they can also be engaged with the inner side wall of the sliding groove 21126 to prevent the bending member 250 from slipping out of the accommodation space D. At the same time, in order to prevent the protrusions 251 from sliding out of the second assembly groove 21125, after the bending member 250 is assembled with the first box body 2112, the second assembly groove 21125 can also be blocked. Correspondingly, the second box body 2122 of the second housing 212 can also be provided with the same structure as the first box body 2112, such that the other end of the bending member 250 can be slidably connected to the second box body 2122, which will not be elaborated here.

[0108] In this way, before the device main body 200 is bent, the bending member 250 can be accommodated within the accommodation space D of the first housing 211 and the second housing 212. When the device main body 200 needs to be bent, the first housing 211 or the second housing 212 can be pulled, such that the bending member 250 can slide out of the accommodation space D for bending, thereby achieving the purpose of bending the device main body 200 after it is extended. Among them, the material of the bending member 250 can be soft rubber, so that the bending member 250 can have a bending property. At the same time, a conductive circuit can also be embedded within the bending member 250, such that the bending member 250 can also be used to realize the electrical connection of the electronic devices 230 within the first housing 211 and the second housing 212.

[0109] In some embodiments, the bending member 250 is not limited to soft rubber. It can also be composed of a plurality of rotatably connected housings 210 as in the foregoing embodiments, so that it can have the ability to bend. In addition, in some embodiments, only one of the first housing 211 and the second housing 212 may be slidably connected to the bending member 250, rather than both adjacent housings 210 being slidably connected to the bending member 250. As long as one of the adjacent two housings 210 can slide in a direction closer to or farther from the other, the device body 200 can be telescoped. At the same time, the bending member 250 can also be slidably connected to the outer surface of the first box body 2112 and / or the second box body 2122, rather than being limited to being received in the accommodation space D.

[0110] The limiting component 260 can be used to provide a force to limit the sliding of the first housing 211 and the second housing 212 and maintain the flattened state of the first housing 211 and the second housing 212. As Figure 35 shown, the limiting component 360 can be provided with a first limiting member 361 and a second limiting member 362. The first limiting member 261 can be disposed in the fixing groove 21128 of the first box body 2112, and the second limiting member 262 can be disposed in the fixing groove 21128 of the second box body 2122. And the first limiting member 261 and the second limiting member 262 can be magnetically connected to provide a magnetic force to limit the sliding of the first housing 211 and the second housing 212 and maintain the flattened state of the first housing 211 and the second housing 212. When the device body 200 needs to be extended, the user can overcome the magnetic force generated by the first limiting member 261 and the second limiting member 262 to pull the first housing 211 or the second housing 212, so that the device body 200 can be extended, and then the bending of the device body 200 after extension can be realized. Among them, both the first limiting member 261 and the second limiting member 262 can be magnets to improve the strength of the magnetic connection between the two. Of course, only one of the first limiting member 261 and the second limiting member 262 can be a magnet, and the other can be an object attracted by magnetic force, such as metal.

[0111] In some embodiments, in order to prevent the first housing 211 and the second housing 212 from being misaligned under the influence of external forces, one of the first housing 211 and the second housing 212 can be provided with a convex block, and the other can be provided with a matching concave pit. When the first limiting member 261 and the second limiting member 262 are magnetically connected, the convex block can be disposed in the concave pit, so that the first housing 211 and the second housing 212 can be positioned and connected through the convex block and the concave pit.

[0112] Please refer to Figure 36 , Figure 36 is Figure 35 a partial structural schematic diagram of the first box body 2112, the second box body 2122, the bending member 250 and the limiting component 260 in another embodiment in

[0113] In some embodiments, in addition to maintaining the flattened state of the first shell 211 and the second shell 212 by means of magnetic force, the flattened state of the first shell 211 and the second shell 212 can also be maintained by means of deformation force. For example, the limit assembly 260 can also be provided with a plug-in component 263, a spring 264 and a pusher 265. Figure 36 As shown, the connector 263 can be arranged on the first box body 2112, and the connector 263 can be provided with a slot 2631. The second box body 2122 can be provided with a slot 21224 corresponding to the connector 263, and the spring 264 can be arranged in the slot 21224. The pusher 265 can be arranged on the second box body 2122, and the pusher 265 can be connected with the spring 264, and can push the spring 264 to undergo elastic deformation. In this way, when the first box body 2112 and the second box body 2122 are connected, the connector 263 can be inserted into the slot 21224 and abut against the spring 264, so that the spring 264 undergoes elastic deformation, providing a space for the insertion of the connector 263. When the connector 263 is inserted into place, the spring 264 can be in the slot 2631 that is inserted into the connector 263, and is engaged with the connector 263. When the first box body 2112 and the second box body 2122 need to slide, the spring 264 can be elastically deformed by pressing the pusher 265, providing a space for the connector 263 to exit the slot 21224, so that the connector 263 can exit the slot 21224, thereby achieving the sliding between the first box body 2112 and the second box body 2122. Compared with the magnetic connection method, the reliability and stability of the connection between the first box body 2112 and the second box body 2122 in the flat state can be improved.

[0114] In some embodiments, the bending member 250 may not be limited to being arranged between the first shell 211 and the second shell 212, but may be arranged between any two adjacent shells 210 and slidably connected with the two shells 210 to achieve the telescopic movement of the device body 200. At the same time, the bending member 350 may not be limited to one, for example, the first shell 211 and the second shell 212 may be telescopically bent through the bending member 350, and the second shell 212 and the third shell 213 may also be telescopically bent through the bending member 350. Similarly, the fourth shell 214 may be rotatably connected with the third shell 213 as in the aforementioned embodiment, or may be telescopically bent with the third shell 213 through the bending member 350. That is, the bending member 350 may be used for telescopic bending between multiple adjacent shells 210, or the rotating shaft 21222 may be used for rotational bending as in the aforementioned embodiment, or both bending methods may be used at the same time, and the specific connection method may be adjusted according to design requirements, which is not limited in this embodiment.

[0115] In addition, it should be noted that the multiple housings 210 of the device main body 200 in this embodiment can also be divided into multiple main bodies, and two adjacent main bodies can be slidably connected through a bending member 250. For example, the first housing 211 can form one main body of the device main body 200, and the second housing 212, the third housing 213, and the fourth housing 214 can form another main body of the device main body 200, so that two adjacent main bodies can be telescoped and bent after being extended. Or, the first housing 211 and the second housing 212 can form one main body of the device main body 200, and the third housing 213 and the fourth housing 214 can form another main body of the device main body 200, and the second housing 212 and the third housing 213 can be telescopically bent through the bending member 250, so that two adjacent main bodies can be telescoped and bent after being extended. Among them, with the different numbers of the housings 210, the division of the main bodies is also different, and it only needs to ensure that two adjacent main bodies can be telescopically bent through the bending member 250.

[0116] Please refer to Figure 37 , Figure 37 is Figure 31 the partial enlarged view of the S position in

[0117] Since the device main body 200 can be telescoped, the designed length of the strap 300 can be reduced. When the other end of the strap 300 is detached from the frame 120, the other end can be connected to the fourth housing 214, so that the shorter strap 300 can be fixed on the fourth housing 214 without occupying the areas on the first housing 211, the second housing 212, and the third housing 213. As Figure 37 shown, the fourth housing 214 can also be provided with the same limiting posts 21124 as those on the first housing 211, so that the fourth housing 214 can cooperate with the positioning holes 320 of the strap 300 through the limiting posts 21124 to achieve the detachable connection between the fourth housing 214 and the strap 300.

[0118] The wearing bracket 400 can be used to carry the display module 100 and the device main body 200, so that the user can wear the display module 100 and the device main body 200 on the head through the wearing bracket 400 to present a virtual reality or augmented reality environment in front of the user's eyes. As Figure 1As shown, the wearing bracket 400 may be provided with a lens frame 410 and temple arms 420. The lens frame 410 may be worn above the user's nose, that is, in front of the user's eyes. The temple arms 420 may be provided on opposite sides of the lens frame 410, and the temple arms 420 may be worn on the user's ears. In this way, the cooperation between the lens frame 410 and the temple arms 420 can realize the wearing function of the wearing bracket 400, so that the user can wear the display module 100 and the device body 200 on the head through the wearing bracket 400 for use. In some embodiments, the near-eye display device 10 may also be provided only with the display module 100 and the device body 200, and the wearing bracket 400 may be an independent component, and the specific structure of the wearing bracket 400 may refer to the existing glasses structure.

[0119] Furthermore, the lens frame 410 may also be used to install corresponding functional lenses, and the temple arms 420 may also be used to detachably connect to the device body 200. Among them, the lens frame 410 may be used to install functional lenses such as plain glasses, anti-glare glasses, colored glasses, myopia glasses, etc., so that the wearing bracket 400 can still be worn on the user's head as common glasses after being detached from the device body 200. When the display module 100 is worn on the user's head, it may be disposed opposite to the functional lens on the lens frame 410. The temple arms 420 and the display module 100 may be detachably connected by means such as magnetic attraction and buckles, so that the user can replace the wearing bracket 400 or the display module 100 and the device body 200 with different functions or styles according to needs. For example, magnets may be provided on the temple arms 420, and magnets may also be provided on the second cover 2121 of the second housing 212 of the device body 200, so that the temple arms 420 can be magnetically connected to the device body 200.

[0120] The near-eye display device 10 provided by the embodiments of the present application can not only utilize the display module 100 and the device body 200 to realize the functions of the virtual reality or augmented reality environment of the near-eye display device 10, but also bend the device body 200 in the flattened state in the direction close to the display module 100, and jointly enclose a wearing space A with the display module 100. In this way, the user can wear the bent device body 200 and the display module 100 on the wrist through the wearing space A for carrying, improving the portability of the near-eye display device 10.

[0121] The above are only some embodiments of the present application, and thus do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
