[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0017] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] This application describes a near-eye display device. This near-eye display device can be an augmented reality (AR) or virtual reality (VR) device, such as AR or VR glasses. Of course, this near-eye display device can also be other devices that need to be worn on the head, such as glasses, or devices with other functions such as lighting that can be worn on the head, which will not be elaborated further. The following detailed description uses AR or VR glasses as an example.

[0019] In examples of augmented reality or virtual reality glasses, the near-eye display device can be configured to transmit and receive data from an external processing device via a signaling connection, which can be wired, wireless, or a combination thereof. However, in other cases, the near-eye display device can be used as a standalone device, i.e., data processing occurs within the near-eye display device itself. The signaling connection can be configured to carry any type of data, such as image data (e.g., still images and / or fully moving 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, personal computer, tablet computer, smartphone, or other type of processing device. The signaling 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), or a combination thereof. Additionally, the external processing device can communicate with one or more other external processing devices via a network, which may be, for example, a local area network (LAN), a wide area network (WAN), an intranet, a metropolitan area network (MAN), the Internet, or a combination thereof.

[0020] Near-eye display devices may include display components, optics, sensors, and processors. In examples of augmented reality or virtual reality glasses, the display components are designed to, for example, function as virtual reality glasses by projecting light into the user's eyes, or as augmented reality glasses by projecting light into the user's eyes to overlay an image onto the user's view of their real-world environment. Near-eye display devices may also include an ambient light sensor and an electronic circuitry system to control at least some of the aforementioned components and perform associated data processing functions. The electronic circuitry system may include, for example, one or more processors and one or more memories.

[0021] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the charging system 5 provided in the embodiments of this application. Figure 2 yes Figure 1 A schematic diagram of the charging system 5 from another perspective. Figure 3 yes Figure 1 A schematic diagram of the structure of the near-eye display device 10.

[0022] like Figures 1 to 2 As shown, the charging system 5 provided in this embodiment may include a near-eye display device 10 and a charging device 20. The near-eye display device 10 can be placed on the charging device 20 and electrically connected to it, allowing the charging device 20 to charge the near-eye display device 10. In this embodiment, the charging device 20 not only improves the charging convenience of the near-eye display device 10, but also provides containment and protection for the near-eye display device 10 during the charging process.

[0023] The near-eye display device 10 can realize virtual reality or augmented reality functions in front of the user's eyes. For example... Figure 3 As shown, the near-eye display device 10 can be provided with two functional modules, namely a first module 110 and a second module 120. The first module 110 and the second module 120 can be simultaneously placed on the charging device 20 for charging. Alternatively, they can be placed separately on the charging device 20 for charging. In this embodiment, the first module 110 can be used to realize virtual reality or augmented reality functions in front of the user's eyes, and the second module 120 can be used to enhance the functions of the first module 110 or to assist the first module 110 in realizing other functions. The terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," or "third" may explicitly or implicitly include at least one of that feature.

[0024] The first module 110 may include a module body 111 and a functional lens 112. For example... Figure 3As shown, the module body 111 can be connected to the functional lens 112, and the two can form an angle, allowing the first module 110 to be shaped like a spoon to facilitate its fit with the user's head. The functional lens 112 can present a virtual reality or augmented reality environment in front of the user's eyes under the control of the module body 111. For example, the module body 111 can be equipped with an optical engine, while the functional lens 112 can be an optical waveguide, specifically a planar grating waveguide such as a diffraction grating waveguide. Thus, the near-eye display device 10 can utilize the module body 111 and the functional lens 112 to achieve virtual reality or augmented reality functions. In this embodiment, the angle formed between the module body 111 and the functional lens 112 can be adjusted according to the user's head size; this embodiment does not limit this. Furthermore, the specific imaging principles and structures of the module body 111 and the functional lens 112 can be found in existing technologies and will not be elaborated here. In some embodiments, the first module 110 can also be used to implement functions other than virtual reality or augmented reality.

[0025] In some embodiments, the module body 111 can be rotatably connected to the functional lens 112, allowing the functional lens 112 to be folded to improve the portability of the first module 110. In some embodiments, the module body 111 can also be detachably connected to the functional lens 112, allowing the module body 111 to be used as an independent module after being detached from the functional lens 112 to achieve other functions and enhance the functional versatility of the near-eye display device 10.

[0026] In some embodiments, when the first module 110 can be used to realize functions other than virtual reality or augmented reality, the functional lens 112 can be a vision correction lens made of one or more lenses such as convex lenses and concave lenses, and other types of lenses or functional lenses (such as plano lenses, anti-glare lenses, tinted lenses and myopia lenses) or functional films (such as anti-reflective films, polarizing films, filter films, etc.) can also be provided in the vision correction lens.

[0027] In some embodiments, the functional lens 112 may also be a photochromic device. For example, the photochromic device may be made of a photochromic material, so that the photochromic device can change color after being excited by light of a certain wavelength. The photochromic material can be manufactured using existing technical solutions within the scope understood by those skilled in the art, and will not be elaborated further. Alternatively, the functional lens 112 may also be an electrochromic device. For example, the electrochromic device may be made of an electrochromic material. The electrochromic material may be one of inorganic electrochromic materials and organic electrochromic materials. The inorganic electrochromic material may be tungsten trioxide. The organic electrochromic material may be one of polythiophene compounds and their derivatives, violetin compounds, tetrathiofulvalene compounds, metal phthalocyanine compounds, etc. Of course, the electrochromic material can be manufactured using existing technical solutions within the scope understood by those skilled in the art, and will not be elaborated further.

[0028] The second module 120 can be similar to the module body 111 of the first module 110, and can be used to enhance or assist the first module 110 in achieving corresponding functions. In some embodiments, the second module 120 can also be a module independent of the first module 110, which can independently realize virtual reality or augmented reality functions or other functions, such as shooting, lighting, and audio playback, to enhance the functional diversity of the near-eye display device 10. Meanwhile, the first module 110 and the second module 120 can be connected wirelessly or wiredly, allowing them to work together to realize the functions of the near-eye display device 10. Furthermore, in some embodiments, the near-eye display device 10 may only have the first module 110 or the second module 120, that is, the near-eye display device 10 may only have one functional module. Of course, the near-eye display device 10 can also have multiple functional modules as needed, such as three, four, or five, etc., and this embodiment does not limit this.

[0029] In some embodiments, the first module 110 and the second module 120 can be directly worn on the user's head. In other embodiments, the near-eye display device 10 may also be provided with a wearing bracket that cooperates with the first module 110 and the second module 120. This wearing bracket can support the first module 110 and the second module 120, allowing the user to wear the first module 110 and the second module 120 on their head to present a virtual reality or augmented reality environment in front of the user's eyes. Simultaneously, to facilitate charging of the first module 110 and the second module 120, the wearing bracket can also be detachably connected to the first module 110 and the second module 120 respectively. For example, the first module 110 and the second module 120 can be magnetically connected to the wearing bracket respectively. Thus, the user can remove the first module 110 and the second module 120 from the wearing bracket and place them on the charging device 20 for charging.

[0030] All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0031] Please combine Figures 1 to 2 See Figures 4 to 5 , Figure 4 yes Figure 1 A schematic diagram of the structure of the charging device 20. Figure 5 yes Figure 4 A schematic diagram of the charging device 20 from another perspective.

[0032] The charging device 20 can be used to charge the functional modules, thereby improving the charging convenience of the near-eye display device 10. For example... Figures 4 to 5 As shown, the charging device 20 may include: a housing 200, an electrical connection terminal 300, a connector 400, and a charging interface 500. The housing 200 can be used to house the functional module and also to install the electronic components required by the charging device 20. The electrical connection terminal 300 can be disposed on the housing 200 and can be used to electrically connect with the functional module to transmit electrical energy and realize the charging function of the charging device 20. The connector 400 can also be disposed on the housing 200 and can provide guidance for the functional module when it is placed on the housing 200, thereby improving the accuracy of the connection between the functional module and the electrical connection terminal 300. The charging interface 500 can also be disposed on the housing 200 and can be used to connect to an external power source to power the charging device 20. In this embodiment, the charging device 20 not only improves the charging convenience of the functional module but also accommodates and protects the functional lens 112 of the functional module during the charging process.

[0033] The housing 200 can be used to house the functional modules and the electronic components required for mounting the charging device 20. For example... Figure 1 and Figure 4As shown, the housing 200 can be shaped like a spoon to match the shape of the first module 110. The opposite sides of a portion of the housing 200 at the handle can respectively accommodate the first module 110 and the second module 120, while a portion of the housing 200 at the head can have a receiving groove 201 that extends through the head, connecting the opposite sides of the housing 200. Thus, when the first module 110 is placed on the housing 200, the module body 111 can be placed at the handle, and the functional lens 112 can be placed in the receiving groove 201 at the head, allowing the housing 200 to contain and protect the functional lens 112. Furthermore, the housing 200 can also have a receiving space for installing electronic components required by the charging device 20, such as circuit boards, batteries, and sensors, to enable the charging function of the charging device 20.

[0034] The housing 200 may also include a front shell 210 and a rear shell 220. The front shell 210 can be connected to the rear shell 220, and the two can be positioned opposite each other. The front shell 210 can house the first module 110, and the rear shell 220 can house the second module 120, allowing both modules to be simultaneously placed on the housing 200 for charging. A receiving slot 201 extends through the front shell 210 and the rear shell 220, connecting opposite sides of the housing 200, allowing the functional lens 112 of the first module 110 to be housed and protected within the receiving slot 201. Simultaneously, the front shell 210 and the rear shell 220 can jointly enclose the aforementioned receiving space for installing the electronic components required by the charging device 10. In this embodiment, the front shell 210 and the rear shell 220 can be made of plastic, giving the housing 200 a certain rigidity and light weight for easy carrying by the user. Of course, the housing 200 can also be made of other materials, and this embodiment does not limit this.

[0035] The front housing 210 can be disposed on one side of the rear housing 220, and the front housing 210 can be used to house the first module 110. For example... Figure 1 and Figure 4As shown, a first groove 211 can be provided on the side of the front shell 210 opposite to the rear shell 220, and the first groove 211 can communicate with the receiving groove 201, which can be used to place the module body 111 of the first module 110. Thus, when the first module 110 is placed on the front shell 210, the module body 111 can be placed in the first groove 211 and electrically connected to the electrical connection terminal 300 for charging, while the functional lens 112 can be placed in the receiving groove 201 for containment and protection. The front shell 210 can also be spoon-shaped to match the shape of the first module 110. The first groove 211 can connect the handle and the head of the front shell 210, and the receiving groove 201 can penetrate the head of the front shell 210, allowing the first groove 211 to communicate with the receiving groove 201. In this embodiment, the inner wall of the first groove 211 can also be designed as an arc surface, which not only makes it easier for the user to grip the first module 110, but also gives the front shell 210 a smooth surface, thereby improving the appearance and refinement of the shell 200. In some embodiments, the shape of the front shell 210 can also be adjusted according to the shape or design requirements of the functional module.

[0036] Furthermore, the front shell 210 may also be provided with a first limiting part 212, which may be located within the first groove 211. This first limiting part 212 can be used to limit the displacement of the module body 111 within the first groove 211, thereby ensuring the reliability of the electrical connection between the module body 111 and the electrical connection terminal 300. For example, the first limiting part 212 may be provided with a first boss 2121, which may protrude from within the first groove 211. Correspondingly, the module body 111 may be provided with a recess that matches the first boss 2121. When the module body 111 is placed into the first groove 211, the first boss 2121 can be inserted into the corresponding recess on the module body 111, allowing the two to engage and thus limiting the displacement of the module body 111 within the first groove 211. In this embodiment, the first limiting portion 212 may be a part of the inner wall of the first groove 211, and the first boss 2121 may be formed by a portion of the first limiting portion 212 protruding outwards. In some embodiments, the first limiting portion 212 may also be directly the first boss 2121.

[0037] In some embodiments, the first limiting part 212 may also be provided with a recess, while the module body 111 may be provided with a matching boss. Thus, when the module body 111 is placed in the first recess 211, the boss of the module body 111 can be inserted into the recess of the first limiting part 212, so that the module body 111 can be engaged with the first limiting part 212, that is, the front shell 210, thereby ensuring the reliability of the electrical connection between the module body 111 and the electrical connection terminal 300.

[0038] In some embodiments, one side of the front shell 210 can also be directly used to place the first module 110 without providing the first groove 211. That is, the side of the front shell 210 used to place the first module 110 can be a plane, as long as the first limiting part 212 can restrict the displacement of the module body 111 and prevent the module body 111 from sliding relative to the front shell 210. Of course, the side of the front shell 210 used to place the first module 110 is not limited to a plane, and its specific shape can be adaptively adjusted according to the actual structure of the first module 110. This embodiment does not limit this.

[0039] The rear cover 220 can be used to house the second module 120, allowing the charging device 10 to simultaneously house two functional modules for charging. For example... Figure 2 and Figures 4 to 5 As shown, a second groove 221 can be provided on the side of the rear shell 220 opposite to the front shell 210, and the second groove 221 can communicate with the receiving groove 201, which can be used to place the second module 120. In this way, the first module 110 and the second module 120 can be placed on the shell 200 for charging at the same time, so as to improve the charging convenience of the functional modules. In this embodiment, the inner wall surface of the second groove 221 can also be designed with a curved surface to fit the first groove 211, thereby improving the appearance and refinement of the shell 200.

[0040] The rear shell 220 may be provided with a connected support portion 222 and an extension portion 223, and the support portion 222 and the extension portion 223 may also form an angle, so that the rear shell 220 may also be shaped like a spoon to connect with the front shell 210 to form a spoon-shaped shell 200. For example, the support portion 222 may be connected to the handle of the front shell 210, and the extension portion 223 may be connected to the head of the front shell 210. The second groove 221 may be provided on the side of the support portion 222 away from the front shell 210 and communicate with the extension portion 223. The receiving groove 201 may penetrate through the extension portion 223 to connect the first groove 211 and the second groove 221, avoiding the problem of dust accumulation in the receiving groove 201 during long-term use of the charging device 20. The end of the support portion 222 away from the extension portion 223, that is, the end of the rear shell 220 at the handle, can be used to support the entire charging device 20. The end of the extension 223 away from the support 222, that is, the end of the rear shell 220 at the spoon-shaped end, can also be used to support the entire charging device 20. In this way, the shell 200 can be placed on a table in the shape of an inverted spoon, improving the stability of the charging device 20 on the table. Simultaneously, the shell 200 can also arch away from the table, allowing for a gap between the support 222 and the extension 223 and the table, thereby utilizing this gap, together with the second recess 221, to accommodate the second module 120.

[0041] The rear cover 220 may also be provided with a second limiting part 224, which may be disposed within the second groove 221. This second limiting part 224 can be used to limit the displacement of the second module 120 within the second groove 221, thereby ensuring the reliability of the electrical connection between the second module 120 and the electrical connection terminal 300. For example, the second limiting part 224 may be provided with a second boss 2241, which protrudes from within the second groove 221. Correspondingly, the second module 120 may be provided with a recess that matches the second boss 2241. When the second module 120 is placed into the second groove 221, the second boss 2241 can be inserted into the corresponding recess on the second module 120, allowing them to engage and thus limiting the displacement of the second module 120 within the second groove 221. In this embodiment, the second limiting portion 224 may be a part of the inner wall of the second groove 221, and the second boss 2241 may be formed by a portion of the second limiting portion 224 protruding outwards. In some embodiments, the second limiting portion 224 may also be directly the second boss 2241.

[0042] In some embodiments, the second limiting portion 224 may also be provided with a recess, while the second module 120 may be provided with a matching boss. Thus, when the second module 120 is placed in the second groove 221, the boss of the second module 120 can be inserted into the recess of the second limiting portion 224, so that the second module 120 can be engaged with the second limiting portion 224, that is, the rear shell 220, thereby ensuring the reliability of the electrical connection between the second module 120 and the electrical connection terminal 300.

[0043] In some embodiments, one side of the rear shell 220 can also be directly used to place the second module 120 without providing the second groove 221. That is, the side of the rear shell 220 used to place the second module 120 can be a plane, as long as the second limiting part 224 can restrict the displacement of the second module 120 and prevent the second module 120 from sliding relative to the rear shell 220. Of course, the side of the rear shell 220 used to place the second module 120 is not limited to a plane, and its specific shape can be adaptively adjusted according to the actual structure of the second module 120. This embodiment does not limit this.

[0044] The receiving groove 201 can be connected to the first recess 211 and the second recess 221 respectively. Thus, when the first module 110 is placed on the front housing 210, the functional lens 112 of the first module 110 can be placed in the receiving groove 201 for containment and protection during charging. Correspondingly, when the second module 120 also has a functional lens 112, the functional lens 112 of the second module 120 can also be placed in the receiving groove 201 for containment and protection. Furthermore, when both the first module 110 and the second module 120 are placed on the housing 200 for charging, and both have functional lenses 112, the placement positions of the first module 110 and the second module 120 can be differentiated. For example, the first module 110 can be placed slightly to the right, and the second module 120 can be placed slightly to the left, allowing the functional lenses 112 of both modules to overlap within the receiving groove 201. Of course, the size and shape of the receiving groove 201 can also be adjusted, such as increasing the width or depth of the receiving groove 201, to accommodate two functional lenses 112.

[0045] In this way, not only can the first module 110 and the second module 120 be placed in the first groove 211 and the second groove 221 on the housing 200 for simultaneous or separate charging, thus improving the charging convenience of the functional modules, but the receiving slot 201 can also be used to accommodate and protect the functional lens 112 of the first module 110. Furthermore, since the first groove 211 and the second groove 221 are both located on the outer wall of the housing 200, the first module 110 and the second module 120 can be displayed during charging, allowing users to easily grasp or observe them. In addition, since the receiving slot 201 extends through the front housing 210 and the rear housing 220, there is no need to worry about dust accumulation inside the receiving slot 201 during long-term use of the charging device 20, reducing the difficulty of cleaning the charging device 20.

[0046] In some embodiments, the receiving slot 201 may penetrate only the front shell 210 and not the rear shell 220, provided that the functional lens 112 of the first module 110 can be placed within the receiving slot 201. In some embodiments, the housing 200 may also be provided with two receiving slots 201. One receiving slot 201 may communicate with the front shell 210 to receive the functional lens 112 of the first module 110. The other receiving slot 201 may communicate with the rear shell 220 to receive the functional lens 112 of the second module 120.

[0048] An electrical connection terminal 300 can be disposed on the housing 200, which can be used for electrical connection with the functional module to transmit electrical energy and realize the charging function of the charging device 20. For example... Figures 4 to 6 As shown, the electrical connection terminal 300 may be provided with a first electrical connection terminal 310 and a second electrical connection terminal 320. The first electrical connection terminal 310 may be disposed within a first groove 211, and the second electrical connection terminal 320 may be disposed within a second groove 221, allowing the first module 110 to be electrically connected to the first electrical connection terminal 310 for charging, and the second module 120 to be electrically connected to the second electrical connection terminal 320 for charging. In this embodiment, the electrical connection terminal 300 may be a metal contact, a spring, or a pogo pin, etc., and the functional module may be provided with mating components corresponding to the aforementioned electrical connection components to facilitate electrical connection between the electrical connection terminal 300 and the functional module. In some embodiments, the electrical connection terminal 300 may also be a charging coil, and the functional module may be provided with a corresponding charging coil, allowing the charging device 20 to wirelessly charge the functional module.

[0049] The first electrical connection terminal 310 can also be disposed on the first protrusion 2121, and the first electrical connection terminal 310 can also be exposed outside the first protrusion 2121. The second electrical connection terminal 320 can also be disposed on the second protrusion 2241, and the second electrical connection terminal 320 can also be exposed outside the second protrusion 2241. In this way, when the first module 110 and the second module 120 are respectively placed in the first groove 211 and the second groove 221, the first protrusion 2121 and the second protrusion 2241 can be used for positioning, thereby improving the accuracy of docking between the first electrical connection terminal 310 and the first module 110, and between the second electrical connection terminal 320 and the second module 120, and avoiding the problem of low charging efficiency caused by improper docking between the functional module and the electrical connection terminal 300.

[0050] In some embodiments, the first electrical connection terminal 310 may also be disposed in other areas within the first groove 211, provided that the first electrical connection terminal 310 can be electrically connected to the first module 110 when the first module 110 is placed in the first groove 211. Correspondingly, the second electrical connection terminal 320 may also be disposed in other areas within the second groove 221, provided that the second electrical connection terminal 320 can be electrically connected to the second module 120 when the second module 120 is placed in the second groove 221.

[0051] The connector 400 can be disposed on the housing 200, and can be used to guide the functional module when it is placed on the housing 200, thereby improving the accuracy of the mating between the functional module and the electrical connection terminal 300. For example... Figures 4 to 6As shown, the connector 400 may be provided with a first connector 410 and a second connector 420. The first connector 410 may be disposed within a first groove 211, and the second connector 420 may be disposed within a second groove 221. The first connector 410 can be magnetically connected to the first module 110, and the second connector 420 can be magnetically connected to the second module 120. When the first module 110 is placed in the first groove 211, the first connector 410 can attract the first module 110, providing a guiding function. Correspondingly, when the second module 120 is placed in the second groove 221, the second connector 420 can attract the second module 120, providing a guiding function. In this embodiment, the first connector 410 and the second connector 420 may be permanent magnets, and the first module 110 and the second module 120 may be respectively provided with components that can be attracted by magnetic force, such as metal or magnets. Preferably, the corresponding components on the first module 110 and the second module 120 are also permanent magnets to increase the attraction between the connector 400 and the functional module.

[0052] In some embodiments, the first connector 410 and the second connector 420 may also be made of metal, and the corresponding components on the first module 110 and the second module 120 may be permanent magnets, as long as the connector 400 can be magnetically connected to the functional module. In other embodiments, the connector 400 may also be configured as a guide rod or guide groove or other guiding structure, as long as the connector 400 can provide a guiding function for the functional module.

[0053] The first connector 410 can also be disposed on the first boss 2121, and the second connector 420 can also be disposed on the second boss 2241. Thus, when the first module 110 and the second module 120 are respectively placed in the first groove 211 and the second groove 221, the first connector 410 and the first boss 2121 can cooperate to guide and limit the placement position of the first module 110, thereby further improving the docking accuracy between the first module 110 and the first electrical connection terminal 310. Correspondingly, the second connector 420 and the second boss 2241 can also cooperate to guide and limit the placement position of the second module 120, thereby further improving the docking accuracy between the second module 120 and the second electrical connection terminal 320. In this embodiment, the first connector 410 can be embedded in the first boss 2121, and the second connector 420 can also be embedded in the second boss 2241 to improve the bonding strength between the two. Meanwhile, the number of the first connector 410 and the second connector 420 can be multiple, such as two, three or four, to improve the magnetic attraction between the connector 400 and the functional module. It is only necessary that the first module 110 and the second module 120 can be provided with a corresponding number of magnetic components.

[0054] In some embodiments, one side of the first connector 410 and the second connector 420 may also be exposed outside the first boss 2121 and the second boss 2241 to facilitate magnetic connection between the connector 400 and the functional module. In some embodiments, the first connector 410 may also be a part of the first boss 2121, and the second connector 420 may also be a part of the second boss 2241. That is, the material of the first boss 2121 and the second boss 2241 may be doped with magnetic material, so that the first boss 2121 and the second boss 2241 can have magnetic force to magnetically connect with the first module 110 and the second module 120.

[0055] A charging port 500 can be located on the housing 200, which can be used to connect an external power source to power the charging device 20. For example... Figure 4 and Figure 7 As shown, the charging interface 500 can be disposed on the front shell 210, and the charging interface 500 can be located at the end of the spoon handle of the front shell 210. The charging interface 500 can also be electrically connected to the circuit board and battery in the accommodating space, so that an external power source can charge the charging device 20, allowing the user to carry the charging device 20 as a portable power source. In this embodiment, the charging interface 500 can be any one of a micro-USB interface, a Type-C interface, and a Lightning interface, so that the charging interface 500 can be connected to an external power source through the corresponding adapter cable. At the same time, the charging interface 500 can also be a combination of multiple micro-USB interfaces, Type-C interfaces, and Lightning interfaces to increase the types of adapter cables that the charging device 20 can be adapted to, as long as the charging device 20 can be provided with multiple charging interfaces 500.

[0056] In some embodiments, the charging interface 500 can also be a charging plug, which connects directly to the socket, allowing the charging device 20 to connect to an external power source without the need for an adapter cable. For portability, the charging plug can also be screwed into or out of the housing 200, enabling a foldable design. In some embodiments, the housing 200 can also simultaneously provide the aforementioned charging plug and various types of interfaces, allowing the charging device 20 to be charged via different types of adapter cables connected to an external power source, or directly connected to a socket via the charging plug, thus expanding the applicability of the charging device 20. Furthermore, it should be noted that the installation position of the charging interface 500 can be adjusted according to design requirements; it can be located at any position on the housing 200, not limited to the end of the spoon handle on the front housing 210. This embodiment does not impose such limitations.

[0057] Please see Figures 8 to 9 , Figure 8 yes Figure 1A schematic diagram showing the connection between the near-eye display device 10 and the charging device 20. Figure 9 yes Figure 8 A schematic diagram of the connection between the near-eye display device 10 and the charging device 20 in another state.

[0058] The charging device 20 may also be equipped with a protective cover 600, which can cover the housing 200 and fix the functional modules to the housing 200, thereby facilitating user portability. Figures 8 to 9 As shown, the protective sleeve 600 may have an integral main body 610 and a fastening part 620. When the first module 110 and / or the second module 120 are placed on the housing 200, the main body 610 can wrap around the spoon handle area of ​​the housing 200, thereby securing the first module 110 and the second module 120 to the housing 200 and preventing them from falling off during transport due to external forces. The fastening part 620 can wrap around the spoon head area of ​​the housing 200 and fasten with the main body 610. For example, the fastening part 620 may have a metal buckle, and the main body 610 may have a corresponding fastening position, allowing the fastening part 620 to be fastened to the main body 610, thereby confining the housing 200 within the space formed by the main body 610. Thus, when the functional module is charging and the user needs to carry it, the protective case 600 can completely wrap around the functional module and the housing 200, allowing the functional module to form an integral part with the charging device 20 for easy carrying. In this embodiment, the protective case 600 can be made of soft, skin-friendly materials such as leather, rubber, or silicone. When the protective case 600 wraps around the housing 200, the charging device 20 can resemble the shape of a zongzi (sticky rice dumpling). When the protective case 600 is removed from the housing 200, it can be laid flat, folded, or rolled up. Of course, the protective case 600 can also have a fixed shape, as long as the fastening part 620 can move relative to the main body 610 to fasten or open.

[0059] Furthermore, the protective sleeve 600 can also be embedded with magnetic material, and the housing 200 can also be provided with corresponding magnetic material. For example, a first magnet 611 can be embedded in the main body 610, and a second magnet 203 can be provided in the corresponding area of ​​the housing 200. When the protective sleeve 600 is placed around the housing 200, the two can be magnetically connected to further improve the firmness of the protective sleeve 600 around the housing 200. In this way, when the fastening part 620 fails to fasten with the main body 610, the magnetic attraction of the first magnet 611 and the second magnet 203 can reduce the probability of the functional module and the housing 200 falling out of the protective sleeve 600. There can be multiple first magnets 611 and second magnets 203. Thus, when the protective sleeve 600 is placed around the housing 200, multiple first magnets 611 and multiple second magnets 203 can be magnetically connected to further improve the firmness of the protective sleeve 600 around the housing 200. The number and layout of the first magnet 611 and the second magnet 203 can be set according to requirements, and this embodiment does not limit this. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0060] In some embodiments, the main body 610 and the fastening part 620 may also be provided with cooperating magnets, so that the fastening part 620 can be magnetically connected to the main body 610 to enclose the housing 200. In some embodiments, the material of the protective sleeve 600 may also be doped with magnetic materials, so that the protective sleeve 600 has magnetic force to attract the magnets on the housing 200. Of course, in order to avoid the magnetic force of the entire protective sleeve 600 affecting the magnetic devices of the functional module, the protective sleeve 600 may only have magnetic force in a portion of its area, and the specific magnetic force distribution can be set according to requirements. This embodiment does not limit this.

[0061] In some embodiments, the charging device 20 may also be provided with a charging indicator light 700 and a button 800. For example... Figure 8As shown, the charging indicator light 700 can be mounted on the back cover 220, and the charging indicator light 700 can be located in the spoon-shaped area of ​​the back cover 220. It can be used to display the charging status of the functional module and the electrical connection status between the charging device 20 and the functional module. For example, when the functional module is placed on the charging device 20 for charging, the charging indicator light 700 can be red. When the functional module is fully charged, the charging indicator light 700 can be green. When the functional module is not properly connected to the charging device 20, the charging indicator light 700 can be red and flash continuously. The button 800 can also be mounted on the back cover 220, which can be used to control the power on / off of the charging device 20 and connection debugging functions. It should be noted that the installation positions of the charging indicator light 700 and the button 800 are only illustrative. The installation positions of the charging indicator light 700 and the button 800 can be selected according to design requirements, and this embodiment does not limit them.

[0062] The charging device 20 provided in this embodiment has one side of the housing 200 configured to house the first module 110 of the near-eye display device 10, and an electrical connection terminal 300 is provided on the housing 200, so that the first module 110 can be electrically connected to the electrical connection terminal 300 for charging after being placed on one side of the housing 200. Simultaneously, by providing a receiving groove 201 on the housing 200, the functional lens 112 of the first module 110 can be placed in the receiving groove 201 after being placed on one side of the housing 200. Thus, compared to a charging cable, the charging device 20 provided in this embodiment not only improves the charging convenience of the first module 110, but also utilizes the receiving groove 201 to accommodate and protect the functional lens 112 of the first module 110 during the charging process.

[0063] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
