In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0038] In the present application, the term "exemplary" is used to mean "serving as an example, illustration, or explanation". Any embodiment described as "exemplary" in the present application is not necessarily to be construed as more preferred or more advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the present application. Details are set forth for the purpose of explanation in the following description. It should be understood that those of ordinary skill in the art can recognize that the present application can be implemented without these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present application.

[0039] In the examples of the present application, "a plurality" means at least two (including two).

[0040] Near-eye display devices, also known as head-mounted displays or wearable displays, are applied to optical lenses. In some cases, at the technical level, augmented reality (AR), virtual reality (VR), mixed reality (MR), and extended reality (XR) can all be referred to as near-eye displays. The optical lenses in the examples of this application can be goggles, smart glasses, myopia glasses, hyperopia glasses, sports glasses, or other near-eye or head-mounted optical lenses, etc. The user's optical lenses can face the human eyes. The near-eye display device has an optical engine, which can include a microdisplay, such as Micro-LED (Micro Light-Emitting Diode), uLED (micro light-emitting diode), Micro-oled (Micro Organic Light-Emitting Diode), LCoS (Liquid Crystal On Silicon), LCD (Liquid Crystal Display), DMD (Digital Micromirror Device) / DLP (Digital Light Processing), or LBS (Laser Beam Scanning), etc., or any combination of these technologies. It can be understood that the optical engine can also include a micro-optical module, etc. The micro-optical module is arranged in front of the microdisplay, and the light of the display is emitted after passing through the micro-optical module.

[0041] The near-eye display device can also include a circuit board, a battery for supplying power to the optical engine and the circuit board, and electrical components for realizing the electrical connection between each component and the battery. Taking AR glasses as an example, in general, electrical components such as the circuit board and the battery are installed on the temple of the AR glasses, and the optical engine is installed on the optical lens. A channel for wiring is provided outside the optical engine to facilitate power supply to the optical engine. Since in some cases, the temple of the AR glasses needs to rotate relative to the frame, the connection between the optical engine and electrical components such as the battery is affected by the relative movement of the temple, resulting in relative misalignment and short circuits in the wiring between the optical engine and electrical components such as the battery; with the relative movement of the temple, problems such as water ingress are also likely to occur in the wiring parts of the optical engine and electrical components such as the battery, affecting the use of the AR glasses.

[0042] In view of the above problems, the present application provides a near-eye display component for an optical lens, which can be directly mounted on a spectacle frame or an optical lens. The near-eye display component includes a first connecting portion for connecting to the optical lens and a mounting seat for mounting an optical engine; a first electrical component bin for mounting electrical components is provided on the first connecting portion, and a mounting groove for mounting the optical engine is formed in the mounting seat. The mounting seat is located on one side of the first connecting portion along a first direction, and the first direction is arranged at an angle with the axial direction of the mounting groove. In the example of the present application, the first electrical component bin is arranged inside the first connecting portion, which facilitates the installation of electrical components such as batteries on the first connecting portion, reduces the need to separately provide a wiring structure for connecting the battery and the optical engine outside the optical lens, and further reduces problems such as water ingress at the electrical connection parts caused by the relative movement of the temple with respect to the spectacle frame; since the axial direction of the mounting groove is arranged at an angle with the first direction, the mounting seat and the first electrical component bin are arranged along the first direction, which facilitates reducing the thickness of the near-eye display device. After being mounted on the optical lens, it can reduce the visual pressure on the human eye and improve the comfort of the product.

[0043] Please refer to Figure 1 , for ease of description, the following takes the near-eye display component 1 in the example of the present application for an AR glasses as an example for elaboration. The AR glasses may include a spectacle frame 7, an optical lens 2 and temples. The optical lens 2 can be mounted on the spectacle frame 7, and the temples are connected to the spectacle frame 7. The near-eye display component 1 can be mounted on the spectacle frame 7 and / or the optical lens 2, which can reduce the setting of a large battery and other power supply modules on the temples, or reduce the wiring part for connecting the battery and other power supply modules and the near-eye display component 1 between the temples and the optical lens 2, and can reduce problems such as water ingress, open circuit, and short circuit at the wiring part caused by the relative movement of the temples and the lens. The display component 1 can be combined with existing ordinary glasses such as myopia, hyperopia, eye protection, and sports glasses to achieve the function of enhanced display, enabling ordinary glasses to have the augmented reality function of smart glasses.

[0044] Please refer to Figure 2 , Figure 3 and Figure 4 , the present application discloses an example of a near-eye display component 1. The following will be described in detail respectively.

[0045] The near-eye display component 1 includes a first connecting portion 10 and a mounting seat 14. The first connecting portion 10 is used for connecting to the optical lens 2 and / or the spectacle frame. A first electrical component bin 111 for mounting electrical components is provided on the first connecting portion 10; the mounting seat 14 is connected to one side of the first connecting portion 10 along a first direction 2a. The mounting seat 14 forms a mounting groove 141 for mounting the optical engine 4, and the first direction 2a is arranged at an angle with the axial direction of the mounting groove 141.

[0046] Please refer to Figure 3 and Figure 4, the first connecting portion 10 can serve as the main structure of the near-eye display component 1 and is used to connect to the optical lens 2. In this example, a fixing surface 123 can be provided on the first connecting portion 10. The fixing surface 123 can be made of materials such as plastic. The fixing surface 123 is used to connect to the optical lens 2 or to the spectacle frame. In this example, the first connecting portion 10 can be directly connected to the optical lens 2, or can be connected to the optical lens 2 through other intermediate connectors such as magnetic attraction or snap fasteners. In this example, the first connecting portion 10 can be fixedly connected to the optical lens 2. For example, the first connecting portion 10 can be adhered to the optical lens 2 so that the first connecting portion 10 maintains a relatively fixed position on the optical lens 2. In this example, the first connecting portion 10 can be movably mounted on the optical lens 2. For example, the first connecting portion 10 can be slidably connected or rotatably connected relative to the optical lens 2. In this example, the first connecting portion 10 can also be detachably mounted on the optical lens 2. For example, the first connecting portion 10 can be snap-connected or adsorbed on the optical lens 2. A buffer layer can also be provided on the fixing surface 123 to reduce the wear on the optical lens 2.

[0047] Please refer to Figure 3 , Figure 5 and Figure 6 , at least a part of the first connecting portion 10 is a hollow structure, and the first electrical compartment 111 is a hollow cavity opened in the first connecting portion 10. The first electrical compartment 111 is used to install electrical components. The electrical components in the examples of this application include but are not limited to the battery 3, circuit board, etc. For the convenience of description, the following will be described with the battery 3 installed in the first electrical compartment 111.

[0048] The mounting seat 14 is used to mount the optical engine 4. An installation groove 141 is opened on the mounting seat 14. The installation groove 141 can be a through groove penetrating the mounting seat 14 or a counterbore opened on the mounting seat 14.

[0049] The installation groove 141 has an axis. The optical engine 4 has a light-emitting surface and an optical axis perpendicular to the light-emitting surface. In some examples, the light-emitting surface of the optical engine 4 is located on one side of the axis of the installation groove 141. In this example, the light-emitting surface of the optical engine 4 can be perpendicular to the axis direction of the installation groove 141, and the corresponding optical axis of the optical engine 4 can be parallel to the axis of the installation groove 141; or, the light-emitting surface of the optical engine 4 is not perpendicular to the axis of the installation groove 141, and the optical axis of the optical engine 4 is arranged at an angle with the first direction, and the optical axis of the optical engine 4 can be neither parallel nor coincident with the first direction. As Figure 2 shown, the 2b direction can be the axis of the installation groove 141, and the optical axis of the optical engine 4 can be arranged along the 2b direction. In this example, the mounting seat 14 can be separately provided and connected to the first connecting portion 10, or the mounting seat 14 can be integrally provided with the first connecting portion 10.

[0050] The mounting seat 14 is connected to one side of the first connecting portion 10 along the first direction 2a, so that the mounting seat 14 and the first connecting portion 10 are arranged along the first direction 2a. The first direction 2a is set at an angle with the axial direction of the mounting groove 141, which means that the first direction 2a is not parallel to the axial direction of the mounting groove 141 and does not overlap. Figure 2 and Figure 6 As shown in , the axial direction of the mounting groove 141 can be perpendicular to the first direction 2a. In this example, since the first connecting portion 10 is provided with the first electrical compartment 111 and the mounting seat 14 is provided with the mounting groove 141, when the mounting seat 14 and the first connecting portion 10 are arranged along the first direction 2a, the first electrical compartment 111 and the mounting groove 141 can be arranged substantially along the first direction 2a, so that the first electrical compartment 111 and the mounting groove 141 can be staggered along the first direction 2a. It can be understood that the axial direction of the mounting groove 141 may not be perpendicular to the first direction 2a. When the mounting groove 141 and the first electrical compartment 111 are arranged along the first direction 2a, the thickness of the near-eye display assembly 1 in the axial direction of the mounting groove 141 can also be reduced to a certain extent. After the optical machine 4 is installed in the installation groove 141 and the battery 3 is installed in the first electrical compartment 111, since the battery 3 and the optical machine 4 can be roughly distributed along the first direction 2a, the axial side of the installation groove 141 can be used as the light output side of the optical machine 4. When the near-eye display component 1 is installed on the outer side of the optical lens 2 and the light passes through the optical lens 2 to enter the human eye, the overall thickness of the near-eye display component 1 on the optical lens 2 is relatively small, and the optical machine 4 can be powered without increasing the overall thickness of the AR device; when the near-eye display component 1 is installed on the inner side of the optical lens 2, the light does not pass through the lens, and the light can directly enter the human eye. Since the overall thickness of the near-eye display component 1 does not need to be increased, the intrusion of the near-eye display component 1 on the human eyeball can be reduced, thereby reducing the sense of oppression brought to the user by the near-eye display component 1, thereby improving the comfort of the product. In the example of the present application, the first electrical compartment 111 and the mounting groove 141 are arranged along the first direction 2a, so that the electrical structures such as the battery 3 in the first electrical compartment 111 and the optical machine 4 in the mounting groove 141 can maintain relative balance on the near-eye display component 1 to balance the weight of the near-eye display component 1, which helps to improve the stability of the near-eye display component 1 on the optical lens 2.

[0051] In this example, since the battery 3 or the relevant circuit board can be directly installed in the first electrical compartment 3, it is possible to reduce the electrical components for connecting the optical engine 4 and the battery 3 that are additionally provided at the connection between the temple and the frame 7 of the AR device. On the one hand, it is possible to reduce the problems of water ingress or wear at the electrical component part caused by the relative movement between the temple and the frame 7. On the other hand, it is possible to reduce the complexity of the connection part between the temple and the frame 7 and simplify the structure of the AR device. In some application scenarios, the near-eye display component 1 can work independently without connecting the electrical components of the temple (such as displaying image content, etc.), greatly improving the portability and mobility of the display component 1, and can be compatible with other traditional head-mounted devices such as near / far vision, eye protection, helmets, etc., and the application scenarios are more diverse.

[0052] In this example, a first wire passing hole 15 directly communicating with the inside of the first electrical compartment 111 and the mounting groove 141 can be opened on the first connection part 10, so as to connect the battery 3 and the optical engine 4 from the inside of the near-eye display component 1 through electrical components. By installing the battery 3 inside the first connection part 10, it is possible to reduce the opening of wiring structures outside the first connection part 10 or the mounting seat 14. When encapsulating the near-eye display component 1, the encapsulation steps can be simplified and the production efficiency of the product can be improved. In this example, a first wire passing hole 15 communicating with the first electrical compartment 111 and the outer wall of the first connection part 10 can also be opened on the first connection part 10, and the electrical structure passing through the first wire passing hole 15 is connected to the battery 3 and the optical engine 4 inside the first electrical compartment 111.

[0053] The optical engine 4 in the example of this application may include an optical module 42 and a microdisplay 41. The optical module 42 and the microdisplay 41 can be connected and fixed to each other, or the optical module 42 and the microdisplay 41 can be respectively connected and fixed to the mounting seat 14.

[0054] Please refer to Figure 2 、 Figure 3 and Figures 7 to 10 , in some examples, the first connection part 10 includes a first cover body 11 and a second cover body 12; the first cover body 11 is provided with a first electrical compartment 111; the second cover body 12 is covered on the first cover body 11, and the second cover body 12 is used to close the first electrical compartment 111; at least one of the first cover body 11 and the second cover body 12 is connected to the mounting seat 14.

[0055] The first electrical compartment 111 can be a groove opened on the first cover body 11. The first electrical compartment 111 can have an opening, and the battery 3 can be put into the first electrical compartment 111 through the opening.

[0056] The second cover body 12 is connected to the first cover body 11 and can be used to close the opening of the first electrical compartment 111.

[0057] Please refer to Figure 2 、Figure 3 and Figure 7 and Figure 8 In this example, the opening of the first electrical appliance compartment 111 can be formed on one side of the first cover 11 along the second direction 2b. The second cover 12 can be closed on the first cover 11 along the second direction 2b, and the second direction 2b can be parallel to the axial direction of the mounting groove 141. In this example, the end face of the first cover 11 facing away from the second cover 12 can be used as the fixing surface 123 of the first connecting portion 10, or the end face of the second cover 12 facing away from the first cover 11 can be used as the fixing surface 123 of the first connecting portion 10.

[0058] Please refer to Figure 9 and Figure 10 In this example, the opening of the first electrical appliance compartment 111 can be formed on one side of the first cover 11 along the first direction 2a, and the opening of the first electrical appliance compartment 111 can be arranged away from the mounting base. The second cover 12 can be closed on the first connecting portion 10 along the first direction 2a.

[0059] In this example, by using the combination of the first cover 11 and the second cover to form the first connecting portion 10, it is convenient to form the first electrical appliance compartment 111 on the first cover 11, and during the processing of the first cover 11, it is convenient for forming and mold opening. In this example, the first cover 11 and the second cover 12 can be fixedly connected to each other. For example, the first cover 11 and the second cover 12 can be adhesively fixed to each other. In this example, the first cover 11 and the second cover 12 can also be detachably connected. For example, the first cover 11 and the second cover 12 can be snap-connected or thread-connected to each other. In some examples, a positioning post 124 is protruded on one of the first cover 11 and the second cover 12, and a positioning hole 117 is formed on the other one. The positioning post 124 can be embedded in the positioning hole 117 to facilitate the mutual positioning and installation of the first cover 11 and the second cover 12.

[0060] At least one of the first cover 11 and the second cover 12 in this example is connected to the mounting base 14, which means that the mounting base 14 is connected to one of the first cover 11 and the second cover 12, or the mounting base 14 is simultaneously connected to the first cover 11 and the second cover 12. Taking the example that the mounting base 14 and the first connecting portion 10 are snap-connected to each other in this example, the mounting base 14 can be snap-connected to one of the first cover 11 and the second cover 12, or the mounting base 14 can be simultaneously snap-connected to the first cover 11 and the second cover 12.

[0061] Please refer to Figure 4 、 Figure 6 and Figure 7, in some examples, a first wiring groove 113 communicating with the installation groove 141 and the first electrical component bin 111 is formed in the first cover body 11. The first wiring groove 113 is used for allowing the conductive module of the optical machine 4 to pass through and be connected to the electrical component.

[0062] For the convenience of description, in this example, the electrical component is taken as the battery 3. The conductive module can be connected to the corresponding electrode of the battery 3. The first wiring groove 113 communicates with the installation groove 141 and the first electrical component bin 111, so that the conductive module of the optical machine 4 can enter the first electrical component bin 111 through the first wiring groove 113. The conductive module of the optical machine 4 in the example of this application can be a wire, a metal sheet, a flexible circuit board or a copper plating layer, etc. By providing the first wiring groove 113 for arranging the conductive module on the first cover body 11, it is convenient to arrange the conductive module inside the first connection part 10, and the conductive module of the optical machine 4 is not exposed outside the first connection part 10, so as to reduce the problem of water ingress and short circuit at the wiring part. The wiring groove in this example can be a through groove penetrating one end of the first cover body 11 close to the mounting base 14. The first wiring groove 113 in this example can be used for allowing the conductive module of the optical machine 4 to pass through and be connected to the positive electrode of the battery 3, the first wiring groove 113 can also be used for allowing the conductive module of the optical machine 4 to pass through and be connected to the negative electrode of the battery 3, and the first wiring groove 113 can also be used for allowing the conductive module of the optical machine 4 to pass through and be respectively connected to the positive electrode and the negative electrode of the battery 3. In some examples, the second cover body 12 is covered on the first cover body 11 along the second direction 2b described in the above example. The first wiring groove 113 can have an opening facing the second cover body 12, and the second cover body 12 can be covered on the opening of the first wiring groove 113, so that one end of the first wiring groove 113 communicates with the installation groove 141 and the other end communicates with the first electrical component bin 111.

[0063] In some examples, a first wire passing hole 15 is formed in the first cover body 11. One end of the first wire passing hole 15 communicates with the first wiring groove 113, and the other end communicates with the installation groove 141. The first wire passing hole 15 is used for accommodating the conductive module of the optical machine 4, and the conductive module of the optical machine 4 passes through the first wire passing hole 15 and is connected to the electrical component through the first wiring groove 113.

[0064] Please refer to Figure 7 , in some examples, a first sunk groove 112 for accommodating the pole piece is formed in the first cover body 11. The first sunk groove 112 communicates with the first wiring groove 113 and the first electrical component bin 111. The pole piece can be used for connecting the conductive module and the electrical component. For example, the pole piece can be used for connecting the corresponding electrode of the battery 3.

[0065] The first sunken groove 112 communicates with the first wiring groove 113 and the first electrical component bin 111, which means that the first sunken groove 112 has at least openings respectively communicating with the first wiring groove 113 and the first electrical component bin 111, so that the pole piece in the first sunken groove 112 can be used to connect electrical components and the conductive module in the first wiring groove 113. The pole piece described in this example can be a metal sheet or other structures capable of conducting electricity. The first sunken groove 112 in this example can be used as an intermediate connecting piece between electrical components and the conductive module to facilitate the connection between the conductive module and the electrical components. Taking the electrical component as the battery 3 as an example, since the pole piece can be installed in the first wiring groove 113, the pole piece does not occupy the space of the first electrical component bin 111, which can reduce the interference of the pole piece on the battery 3 and improve the convenience of installing the battery 3, and also helps to improve the stability of the battery 3.

[0066] Please refer to Figure 3 、 Figure 4 and Figure 7 , in some examples, taking the electrical component as the battery 3 as an example, the first electrical component bin 111 has an opening facing the second cover 12 and a bottom wall disposed opposite to the opening, and the first sunken groove 112 is opened on the bottom wall of the first electrical component bin 111. The opening of the first electrical component bin 111 is used for the battery 3 to enter the first electrical component bin 111. The bottom wall of the first electrical component bin 111 is disposed opposite to the opening of the first electrical component bin 111. The position of the bottom wall of the first electrical component bin 111 can be the deepest installation position of the battery 3 in the first electrical component bin 111. The first sunken groove 112 is opened on the bottom wall of the first electrical component bin 111 so that after the electrode is installed in the first sunken groove 112, the electrode does not occupy the internal space of the first electrical component bin 111. In some examples, the opening of the first electrical component bin 111 can be located on the side of the first cover 11 away from the mounting seat 14 along the first direction 2a, the second cover 12 can cover the opening of the first electrical component bin 111 along the first direction 2a, the bottom wall of the first electrical component bin 111 can be located on the side of the first electrical component bin 11 close to the mounting seat 14 along the first direction 2a, and the first wiring groove 113 can be connected to the mounting groove 141 and the first sunken groove 112 nearby.

The second wiring groove 116 is used for the conductive module of the light engine 4 to pass through and connect to the electrical component. Taking the electrical component in this example as a battery, the second wiring groove 116 in this example cooperates with the first wiring groove 113 so that the conductive module of the light engine 4 can be respectively connected to the positive and negative electrodes of the battery 3. Taking the conductive module of the light engine 4 passing through the first wiring groove 113 and connecting to the positive electrode of the battery 3 as an example, the second wiring groove 116 is used for the conductive module of the light engine 4 to pass through and connect to the negative electrode of the battery 3. The electrical component in this example can also be a combination of the battery 3 and the circuit board. The second wiring groove 116 can be used for the conductive module of the light engine to pass through and connect the circuit board and the light engine 4. The first wiring groove 113 in this example can communicate with the second wiring groove 116, or the first wiring groove 113 can be independently arranged with respect to the second wiring groove 116. In some examples, at one end of the first cover 11 close to the installation groove 141, the first wire passing hole 15 described in any of the above examples is provided, and the first wiring groove 113 and the second wiring groove 116 can respectively communicate with the first wire passing hole 15.

[0068] Please refer to Figure 6 and Figure 8 , in some examples, on the side of the second cover 12 facing the first cover 11, a second sunk groove 121 is provided. The second sunk groove 121 is used for accommodating at least one of the battery 3, the circuit board, the magnet 53, and the counterweight. After the first cover 11 and the second cover 12 are mutually covered, the first cover 11 can enclose the second sunk groove 121 of the second cover 12, so that the battery 3, the circuit board, the magnet 53, or the counterweight in the second sunk groove 121 is not exposed outside the first connection portion 10. In this example, by providing the second sunk groove 121, it is convenient to add structures such as the battery 3 inside the first connection portion 10 to extend the battery life of the near-eye display assembly 1. The circuit board structure of the near-eye display assembly 1 can be installed in the second sunk groove 121. While balancing the counterweight of the near-eye display assembly 1 through the circuit board, the circuit board and other structures are accommodated inside the first connection portion 10, reducing the laying of the circuit board outside the near-eye display assembly 1, which helps to simplify the structure of the near-eye display assembly 1 and improve its assembly performance. The second sunk groove 121 can also be used for installing the magnet 53 and / or the counterweight. The near-eye display assembly 1 can be adsorbed on a preset position on the optical lens 2 through the magnet 53, so as to adjust the position of the near-eye display assembly 1 on the optical lens 2 as needed to adapt to users with different pupil distances. The second sunk groove 121 in this example can also be used for installing other functional modules.

[0069] Please continue to refer to Figure 6 and Figure 8, in some examples, the second cover body 12 is covered on the first cover body 11 along the second direction 2b, the second direction 2b is arranged at an angle with the first direction 2a, a third wiring groove 122 is formed in the second cover body 12, and the third wiring groove 122 communicates with the installation groove 141 and the second sinking groove 121. The third wiring groove 122 in this example has at least an opening communicating with the installation groove 141 and the second sinking groove 121, so as to electrically connect the electrical components in the second sinking groove 121 with the optical engine 4. In this example, the second cover body 12 is covered on the first cover body 11 along the second direction 2b, and the second direction 2b may be parallel to the axial direction of the installation groove 141. The depth of the second sinking groove 121 in this example can be determined according to the quantity, shape and volume of the battery 3 and / or circuit board and / or magnet 53 and / or counterweight block to be installed. Optionally, the second sinking groove 121 and the first sinking groove 112 are arranged oppositely to save the internal space of the first connecting part 10. The second sinking groove 121 in this example can facilitate providing sufficient space inside the near-eye display assembly 1, so as to facilitate the expansion of functional components of the near-eye display assembly 1 when needed. In some application scenarios, for example, the adsorption force of a single magnetic attraction on the battery may not be sufficient to support the near-eye display assembly 1 on the optical lens 2. In order to achieve a greater suction clamping force, a metal block or a magnet can be added in the second sinking groove 121 to make the mutual magnetic attraction clamping between the first connecting part 10 and an external magnet more stable.

[0070] Please refer to Figure 2 , Figure 3 and Figure 7In some examples, a through hole 114 is provided on the first connection part 10, one end of the through hole 114 is connected to the first electrical compartment 111, and the other end is passed through the outer wall of the first connection part 10. The through hole 114 is used to allow the power supply device to move inside and outside the first connection part 10; the near-eye display assembly 1 also includes a sealed compartment cover 115, which is used to close the through hole 114. The through hole 114 in this example passes through the side wall of the first connection part 10 and is connected to the first electrical compartment 111, so that the electrical device in the first electrical compartment 111 can move to the outside of the first connection part 10 through the through hole 114. Taking the battery 3 as an example, the battery 3 can enter the first electrical compartment 111 through the through hole 114 to facilitate the installation of the battery 3. The sealed compartment cover 115 is used to be installed on the first connection part 10 so as to close the through hole 114 when necessary. The sealed compartment cover 115 may be annular or have a mounting groove, and the battery 3 may be installed in the sealed compartment cover 115. Since the sealed compartment cover 115 surrounds the battery 3 in the entire circumference, the battery 3 can be put in and taken out. The sealed compartment cover 115 may also be provided with a gripping position so that it can be leaked relative to the first cover body 11, which is convenient for the user to operate. When the battery 3 is installed in the first electrical compartment 111, the battery 3 can be embedded in the first electrical compartment 111 through the through hole 114, and the through hole 114 can be closed with the sealed compartment cover. The sealed compartment cover in this example may be consistent with the shape and size of the through hole 114, so that the sealed compartment cover can completely close the through hole 114; the sealed compartment cover in this example may also cover the outer surface of the first connecting portion 10 to cover the through hole 114 from the outer surface of the first connecting portion 10; the sealed compartment cover in this example may also be partially embedded in the through hole 114 and partially covered on the outer surface of the first connecting portion 10, so as to facilitate the fixing of the sealed compartment cover. Optionally, the first connecting portion 10 includes the first cover body 11 and the second cover body 12 described in any of the above examples, and the through hole 114 can be provided on the first cover body 11 or the second cover body 12. For the convenience of description, the following description is made by taking the through hole 114 provided on the first cover body 11 as an example. In some examples, the first sinking groove 112 described in any of the above examples is provided on the first cover body 11, and the first sinking groove 112 is used to install the pole piece, and the first sinking groove 112 and the through hole 114 can be staggered.

[0071] See also Figure 3 and Figure 6, in some examples, the near-eye display component 1 further includes an annular fixing portion 1151 connected to the sealing chamber cover 115. The annular fixing portion 1151 is used to be sleeved around the periphery of the electrical component, and the through hole 114 is further used to allow the annular fixing portion 1151 to move to the outside of the first connecting portion 10. The annular fixing portion 1151 in this example is used to be sleeved around the periphery of the electrical component. When the sealing chamber cover 115 moves to the outside of the first connecting portion 10 through the through hole 114, the annular fixing portion 1151 can drive the electrical component to move synchronously, thereby facilitating the disassembly and assembly of the electrical component. The annular fixing portion 1151 in this example can be integrally provided with the sealing chamber cover 115, or can be separately provided and connected to the sealing chamber cover 115. The annular fixing portion 1151 in this example can be a complete annular structure or a partially disconnected annular structure.

[0072] Please refer to Figure 2 and Figure 3 , in some examples, the through hole 114 is provided at one end of the first connecting portion 10 away from the mounting seat 14. The through hole 114 is used to allow the electrical component to move along the first direction 2a. In this example, since the mounting seat 14 is provided on one side of the first connecting portion 10 along the first direction 2a, by allowing the electrical component to move along the first direction 2a through the through hole 114, the interference of the mounting seat 14 on the electrical component during the disassembly and assembly of the electrical component can be reduced.

[0073] Please refer to Figure 9 and Figure 10In some examples, the first connection part 10 includes a first cover 11 and a second cover 12. The first cover 11 is connected to the mounting seat 14. The first cover 11 is provided with a first electrical compartment 111. The first cover 11 has an opening connected to the first electrical compartment 111 on one side away from the mounting seat 14. The second cover 12 covers the first cover 11. The second cover 12 covers the opening of the first cover 11 along the first direction 2a. The second cover 12 covers the side of the first cover 11 away from the mounting seat 14 to close the first electrical compartment 111. The opening is used for electrical devices such as the battery 3 to enter the first electrical compartment 111. In this example, by covering the second cover 12 with the first cover 11 along the first direction 2a, the interference of the mounting seat 14 on the second cover 12 can be reduced, and the installation performance of the first cover 11 and the second cover 12 can be improved. In some examples, a second sink groove 121 may be provided on the second cover 12 at a position corresponding to the first electrical compartment 111. When the first cover 11 and the second cover 12 are overlapped to form the first connecting portion 10, the electrical device may be partially located in the second sink groove 121. Optionally, the second sink groove 121 may also be used to install other functional modules such as circuit boards and magnets. In some examples, the first wiring groove 113 described in any of the above examples is provided on the first cover 11 to facilitate the connection between the conductive module of the optical machine 4 and the electrical device; the first wiring groove 113 may be located on the side of the first cover 11 away from the second cover 12.

[0074] See also Figure 4 and Figure 10, in some examples, a convex portion 13 is provided on a side of the first connecting portion 10 close to the mounting base 14. The number of the convex portions 13 is two, and the two convex portions 13 are arranged at intervals. The mounting base 14 is respectively connected to the two convex portions 13, and the two convex portions 13 and the mounting base 14 enclose to form a mounting groove 141. In this example, the two convex portions 13 are arranged at intervals so that the optical engine 4 can be partially located between the two convex portions 13. The mounting base 14 is respectively connected to the two convex portions 13 and encloses with the two convex portions 13 to form a mounting groove 141. In some examples, a groove is recessed on a side of the mounting base 14 facing the first connecting portion 10, and the groove of the mounting base 14 and the gap between the two convex portions 13 enclose to form a mounting groove 141. The convex portion 13 in this example can be used as a connecting part between the first connecting portion 10 and the mounting base 14 to enhance the firmness of the connecting part between the first connecting portion 10 and the mounting base 14. When wiring the optical engine 4, optionally, a first wire passing hole 15 communicating with the mounting groove 141 and the first electrical bin 111 is formed on the first connecting portion 10. The first wire passing hole 15 is used to accommodate the conductive module of the optical engine 4; one end of the first wire passing hole 15 far from the first electrical bin 111 is located between the two convex portions 13. Since the two convex portions 13 are arranged at intervals, the first wire passing hole 15 can be hidden between the two convex portions 13 to reduce the exposure of the conductive module of the optical engine 4 assembly, thereby reducing the problem of water ingress into the near-eye display assembly 1.

[0075] In some examples, one of the mounting base 14 and the convex portion 13 is provided with a clamping member 142, and the other is provided with a clamping groove 131, and the clamping member 142 is clamped in the clamping groove 131. The clamping member 142 and the clamping groove 131 in this example are mutually adapted to mount the mounting base 14 on the convex portion 13. For the convenience of description, the following takes the example that the convex portion 13 is provided with a clamping groove 131 and the mounting base 14 is provided with a clamping member 142 for elaboration. Optionally, the clamping groove 131 in this example can be a straight groove, a T-shaped groove or other groove structures. Optionally, the clamping member 142 in this example can be integrally provided with the mounting base 14 or can be separately provided from the mounting base 14 and connected to the mounting base 14.

[0076] Please refer to Figure 9 and Figure 10 , in some examples, the first connecting portion 10 includes the first cover body 11 and the second cover body 12 described in any of the above examples, and the second cover body 12 covers the first cover body 11 along the first direction 2a. The convex portion 13 described above is provided on a side of the first cover body 11 away from the second cover body 12.

[0077] Please refer to Figures 2 to 8, in some examples, the first connecting portion 10 includes the first cover 11 and the second cover 12 described in any of the above examples, and the second cover 12 covers the first cover 11 along the second direction 2b. The protruding portion 13 described above is provided at one end of the first cover 11 or the second cover 12 close to the mounting seat 14.

[0078] Please refer to Figures 2 to 8 , in some examples, the first connecting portion 10 includes the first cover 11 and the second cover 12 described in any of the above examples, and the second cover 12 covers the first cover 11 along the second direction 2b. The protruding portions 13 are respectively provided at one ends of the first cover 11 and the second cover 12 close to the mounting seat 14, and the engaging member 142 on the mounting seat 14 is simultaneously engaged with the protruding portions 13 of the first cover 11 and the second cover 12. Optionally, the engaging member 142 may have a T-shaped structure, and the engaging grooves 131 are respectively provided on the protruding portions 13 of the first cover 11 and the second cover 12. When the second cover 12 covers the first cover 11, the engaging grooves 131 on the first cover 11 and the second cover 12 enclose to form a T-shaped groove, and the engaging member 142 is engaged with the T-shaped groove to prevent the mounting seat from moving relative to the first connecting portion 10 along the first direction 2a.

[0079] Please refer to Figures 2 to 6 , in some examples, the near-eye display component 1 further includes a fixing seat 6, the fixing seat 6 is installed in the installation groove 141, and a fixing groove 61 for installing the optical engine 4 is provided on the fixing seat 6; a second wire passing hole 62 is provided on the fixing seat 6, and the second wire passing hole 62 is used for accommodating the conductive module of the optical engine 4; one end of the second wire passing hole 62 communicates with the fixing groove 61, and the other end penetrates through to the outer wall of the fixing seat 6.

[0080] The fixing seat 6 is used to install the optical engine 4 on the mounting seat 14, and at the same time, the fixing seat 6 can play a role in protecting the optical engine 4. The fixing groove 61 may be a through groove or a counterbore provided on the fixing seat 6. In this example, the fixing seat 6 may be fixedly connected to the mounting seat 14, or the fixing seat 6 may be movably installed on the mounting seat 14. The second wire passing hole 62 serves as a channel for accommodating the conductive module of the optical engine 4 to facilitate the wiring of the optical engine 4.

[0081] In some examples, a first wire passing hole 15 as described in any of the above examples is provided on the first connecting portion 10, and the second wire passing hole 62 may communicate with the first wire passing hole 15.

[0082] In some examples, the axis of the second wire passing hole 62 is arranged at an angle with the axis of the fixing groove 61. The second wire passing hole 62 in this example is used for the conductive module of the optical engine 4 to pass through, so as to facilitate the connection between the conductive module of the optical engine 4 and the electrical components in the first electrical compartment 111. The shape of the fixing groove 61 in this example can be adapted to the shape of the optical engine 4. The fixing groove 61 has an opening, and the opening of the fixing groove 61 can be arranged on the same side as the light-emitting side of the optical engine 4. The axis of the fixing groove 61 is arranged at an angle with the first direction 2a. Optionally, the axis of the fixing groove 61 can be perpendicular to the plane where the opening of the fixing groove 61 is located. The fact that the axis of the second wire passing hole 62 is arranged at an angle with the axis of the fixing groove 61 means that the axis of the second wire passing hole 62 is neither parallel nor coincident with the axis of the fixing groove 61. In this example, by adopting the above settings, the conductive module of the optical engine 4 can be led out from the side of the fixing base 6, so as to shorten the distance between the conductive module of the optical engine 4 and the first electrical compartment 111. Since the conductive module can be led out from the side of the fixing base 6, the fixing groove 61 can be set as a sunk groove structure in this example, so as to facilitate the sealing between the optical engine 4 and the inner wall surface of the fixing groove 61.

[0083] In some examples, the fixing base 6 is provided with a second electrical compartment 63, and the second wire passing hole 62 communicates with the fixing groove 61 through the second electrical compartment 63. The second electrical compartment 63 in this example can be used to accommodate structures such as an optical engine and a circuit board, so as to place the circuit module of the optical engine 4 inside the fixing base 6, thereby simplifying the structure of the near-eye display component 1, improving the compactness of the product, facilitating the packaging of the product, and at the same time facilitating the functional expansion of the near-eye display component 1. The second electrical compartment 63 communicating with the second wire passing hole 62 can facilitate the lead-out of the conductive module of the optical engine 4 and structures such as a circuit board through the second wire passing hole 62, so as to facilitate wiring.

[0084] Please refer to Figure 4 and Figure 6 , in some examples, one of the outer wall surface of the fixing base 6 and the inner wall surface of the mounting groove 141 is a convex arc surface, and the other is a concave arc surface adapted to the convex arc surface. The mounting groove 141 is used to allow the fixing base 6 to rotate inside to adjust the light-emitting angle of the optical engine 4. The fact that the convex arc surface and the concave arc surface in this example are mutually adapted means that the convex arc surface can be mutually attached to the concave arc surface, so that the fixing base 6 can rotate relative to the mounting groove 141. When the fixing base 6 rotates relative to the mounting base 14, the optical engine 4 on the fixing base 6 can also rotate synchronously, and thus the light-emitting angle of the optical engine 4 can change synchronously. In this example, by adjusting the position of the optical engine 4 relative to the human eye field of view, the position of the optical engine 4 can be accurately adjusted, so as to meet different people with different pupil distances or field of view ranges, and can meet the viewing needs and preferences of different users. On the other hand, it can also provide flexible position testing in the early stage of research and development to achieve the expected design effect.

[0085] The outer surface of the fixed seat 6 in this example can be at least partially spherical, and the inner wall surface of the mounting groove 141 is a concave arc surface, so that the fixed seat 6 can rotate relative to the mounting seat 14 within the mounting groove 141. Optionally, the outer surface of the fixed seat 6 in this example can also be a concave arc surface, and the inner wall surface of the mounting groove 141 can be a convex arc surface, so that the fixed seat 6 can rotate relative to the mounting seat 14 within the mounting groove 141.

The second connecting portion 5 is disposed opposite to the first connecting portion 10 and is used for connecting to the second side of the optical lens 2. The first side and the second side of the optical lens 2 are two opposite sides; the first connecting portion 10 and the second connecting portion 5 are used for clamping the lens with each other and allowing the mounting seat 14 to move on the lens to adjust the position of the light engine 4 relative to the lens.

[0089] In some examples, the second connecting portion 5 can be a component fixedly connected to the first connecting portion. For example, the first connecting portion 10 can be fixed to the second connecting portion 5 by means of bonding, clamping, screw connection, etc. The first connecting portion 10 can also be connected to the second connecting portion 5 through an intermediate connecting member. In some examples, the first connecting portion 10 and the second connecting portion 5 can be independent components, and the first connecting portion 10 and the second connecting portion 5 can cooperate with each other to act as elements for clamping or adsorbing.

[0090] Please refer to Figure 11 , in some examples, at least a part of the second connecting portion 5 is made of a magnetic material. The second connecting portion 5 in this example can be entirely made of a magnetic material or partially made of a magnetic material. As Figure 11As shown in , the second connection part 5 includes a sleeve 51 and a magnet 53 embedded in the sleeve 51. Since the battery 3 and other structures can be adsorbed by the magnet 53, when the first connection part 10 and the second connection part 5 are respectively arranged on both sides of the optical lens 2, the second connection part 5 can adsorb the first connection part 10 to a preset position on the optical lens 2. In some examples, the first connection part 10 includes a first cover body and a second cover body in any of the above examples, and a second sink groove is provided on the second cover body, and the second sink groove can be used to install a magnet to improve the adsorption performance of the first connection part and the second connection part.

[0091] In some examples, a protective member 52 is provided on the second connection portion 5, and the protective member 52 may be a protective film or a protective cover, and the protective member 52 is used to block between the magnet 53 and the optical lens 2 to reduce the wear on the optical lens 2. Optionally, an opening is provided at one end of the sleeve 51 for the magnet 53 to pass through and be embedded in the sleeve 51, and the protective member 52 includes a protective layer 521 and a fixing layer 522 connected to the protective layer 521, and the protective layer 521 covers the opening of the sleeve 51 to block between the magnet 53 and the optical lens 2, and the fixing layer 522 is disposed inside and outside the sleeve 51 to improve the sealing performance of the second connection portion 5.

[0092] See also Figure 1 In some examples, the first connection part 10 has a fixing surface 123, and the fixing surface 123 is arranged opposite to the second connection part 5; the fixing surface 123 is arranged on the same side as the light-emitting side of the optical machine 4; the fixing surface 123 in this example can be a surface on the first connection part 10. The fixing surface 123 is arranged on the same side as the light-emitting side of the optical machine 4. When the near-eye display device is installed, the near-eye display assembly 1 is located on the outside of the optical lens 2, and the second connection part 5 can be located on the inside of the optical lens 2 to reduce the visual intrusion of the near-eye display device to the user and improve the comfort of the product.

[0093] In some examples, the difference from the previous example is that the fixing surface 123 is arranged away from the light exit side of the optical engine 4. The fixing surface 123 in this example can be a surface on the first connecting portion 10. The fixing surface 123 is arranged on the opposite side of the light exit side of the optical engine 4. When the near-eye display device is installed, the near-eye display assembly 1 is located on the inner side of the optical lens 2, and the second connecting portion 5 can be located on the outer side of the optical lens 2.
