Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

In addition, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0053] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be 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 consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0054] The multiple terms in the examples of this application refer to at least two (including two).

[0055] Head-mounted devices are common wearable devices. In some cases, head-mounted devices can have independent operating systems like smartphones. Users can install software, games and other programs provided by software service providers on head-mounted devices. Head-mounted devices can be controlled by voice or motion to complete functions such as adding schedules, map navigation, interacting with friends, taking photos and videos, and making video calls with friends. They can also access wireless networks through mobile communication networks.

[0056] AR glasses are common wearable head-mounted devices. AR glasses generally have frames and temples. The frames can be used to install optical lenses, and the temples can only be used for fixing and supporting. The temples can also be used to install batteries, Bluetooth and other electrical structures.

[0057] Near-eye display devices can create virtual images in the field of view of a single eye or binocular eye. Near-eye display is a technology that renders light field information to the human eye through a display device placed within the non-clear vision distance of the human eye, thereby reconstructing a virtual scene in front of the human eye. Near-eye display devices generally have an optical machine, which includes an optical component and a display component, wherein the optical component can be an optical lens or a combination of optical lenses; the display component can be a microdisplay, which is used to provide display content for the device. It can be a self-luminous active device, such as a light-emitting diode panel micro-OLED (uOLED) and micro-LED (uLED), or a liquid crystal display that requires external light source illumination (including transmissive Liquid crystal display (LCD) and reflective Liquid crystal on silicon (LCOS)), as well as a digital micromirror array (DMD, the core of Digital light processing (DLP)) based on microelectromechanical system (MEMS) technology and a linear beam scanner (LBS).

[0058] Normally, near-eye display devices are generally fixed on head-mounted devices or head-mounted devices, and the optical axis of the near-eye display device can be aligned with the visual axis of the human eye to project the image to the human eye. In order to maintain the stability of the structure, the near-eye display devices on common head-mounted devices or smart glasses are usually fixed. Taking AR glasses as an example, since AR products require perspective (see-through), both the real external world and virtual information must be seen, so one or more optical combiners are needed. Through the form of "stacked", the virtual information and the real scene displayed by the display screen enter the human eye at the same time, blend into one, complement each other, and "enhance" each other. Due to the difference in the distance between the human eyes, when the optical axis of the near-eye display device cannot be aligned with the human eye, its display effect will be greatly affected.

[0059] In order to solve the problem that the near-eye display module on the existing head-mounted device may not be able to align with the human eye, the example of the present application proposes a near-eye display module, in which the assembly shell of the near-eye display module can be moved relative to the head-mounted device to facilitate adjustment of the relative position of the near-eye display module so that the near-eye display module can correspond to the visual axis of the human eye.

[0060] See also Figures 1 to 4The head mounted device 100 in the example of the present application may include a frame 10 and temples 20, wherein the frame 10 has an environment side 101 and an eye side 102, and the light emitting side of the near-eye display module 30 may be oriented toward the human eye side of the frame 10, so that the light output by the near-eye display module 30 may be projected toward the human eye. Optionally, the head mounted device 100 may also have a nose pad 40, and the head mounted device 100 in the example of the present application may be provided with one or two near-eye display modules 30. When two near-eye display modules 30 are provided, the two near-eye display modules 30 may be respectively provided on both sides of the nose pad 40, and the two near-eye display modules 30 may be respectively provided toward the eye side 102. The two near-eye display modules 30 in the example of the present application may both be relatively movably connected to the frame 10, so that the two near-eye display modules 30 may be respectively moved relative to the frame 10, so as to respectively adjust the positions of the optical axes of the two near-eye display modules 30.

[0061] Please refer to Figure 5 and Figure 6 The present application proposes an example of a near-eye display module 30 for a head-mounted device 100, wherein the near-eye display module 30 includes an assembly shell 31 and an optical machine 35; the assembly shell 31 is used to be plugged into the head-mounted device 100, and the assembly shell 31 is configured to be movable relative to the head-mounted device 100; the optical machine 35 is installed on the assembly shell 31.

[0062] The assembly shell 31 is the outer shell of the near-eye display module 30, and the assembly shell 31 can be used to connect to the head-mounted device 100. In the example of the present application, the assembly shell 31 is plugged with the head-mounted device 100, and the assembly shell 31 is configured to be movable relative to the head-mounted device 100. In this example, the assembly shell 31 is plugged with the head-mounted device 100, and the head-mounted device 100 may be provided with a mounting cavity 151, and the assembly shell 31 may be plugged into the mounting cavity 151; or the head-mounted device 100 may be provided with a protruding structure, and the assembly shell 31 may be plugged with the protruding structure on the head-mounted device 100. The assembly shell 31 may include a first outer surface extending in a first direction, the first outer surface being configured to make a first relative movement relative to the head-mounted device 100, and the assembly shell 31 may also include a second outer surface extending in a second direction, the second outer surface being configured to make a second relative movement relative to the head-mounted device 100; the first relative movement is different from the second relative movement, for example, the first relative movement and the second relative movement are the movement or rotation of the assembly shell 31 relative to the head-mounted device 100, for example, the first relative movement may refer to the assembly shell 31 being able to translate or move laterally along a preset direction relative to the head-mounted device 100, and the first relative movement may refer to the assembly shell 31 being able to rotate along a preset direction relative to the head-mounted device 100. Optionally, in the example of the present application, the assembly shell 31 may be able to translate or move laterally along a preset direction relative to the head-mounted device 100. Figure 2The assembly shell 31 can move laterally (translationally) in the first direction 2a, and the assembly shell 31 can also rotate around its axis; optionally, the assembly shell 31 can rotate along a preset direction and at the same time rotate along a preset rotation axis.

[0063] The optical engine 35 is used to project light in a preset direction. The optical engine 35 is mounted on the assembly shell 31, and the optical engine 35 has a light-emitting surface, and the light-emitting surface of the optical engine 35 can be perpendicular to its optical axis. The optical engine 35 can be at least partially installed inside the assembly shell 31, and a display window 3113 can be provided on the assembly shell 31, and the light-emitting surface of the optical engine 35 corresponds to the display window 3113, so that the light of the optical engine 35 can be projected in a preset direction through the display window 3113. The assembly shell 31 in this example can be an integrated structure, and the optical engine 35 can be installed inside the assembly shell 31, and the display window 3113 is formed by a through hole connected to the inside of the assembly shell 31; the optical engine 35 in this example can also be installed at any position outside the assembly shell 31. The assembly shell 31 in this example can also be a split structure, and the assembly shell 31 can be a combination of a first shell 311 and a second shell 312. The optical machine 35 can be installed in the first shell 311 or the second shell 312. Correspondingly, a display window 3113 can be opened on the first shell 311 or the second shell 312 so that the light of the optical machine 35 can be projected to a preset direction. The optical machine 35 in this example can be fixedly connected to the assembly shell 31, and optionally, the optical machine 35 can be detachably connected to the assembly shell 31. The assembly shell 31 in this example can move relative to the head-mounted device 100. When the assembly shell 31 moves, the optical axis of the optical machine 35 also moves synchronously, so that the light projected by the optical machine 35 can be better aligned with the visual axis of the human eye, that is, the light emitting surface of the optical machine 35 and the position of the display window 3113 always remain corresponding in the first relative movement and the second relative movement, thereby ensuring that the light emitting content of the optical machine 35 during the adjustment process can still be accurately emitted from the display window 3113.

[0064] In some examples, a mounting seat 15 is provided on the lens frame 10, and a mounting cavity 151 is provided on the mounting seat 15, and the assembly shell 31 is at least partially embedded in the mounting cavity 151 of the mounting seat 15. In this example, the assembly shell 31 can be generally in a columnar structure, one end of the assembly shell 31 is the first end, and the end opposite to the first end is the second end. The optical machine 35 is arranged near the first end of the assembly shell 31, so that when the assembly shell 31 is installed, the second end of the assembly shell 31 can be inserted into the mounting cavity 151, and the first end where the optical machine 35 is located is located outside the mounting cavity 151.

[0065] In some examples, the assembly shell 31 is provided with a first accommodating groove 3112 and a display window 3113 connected to the first accommodating groove 3112, the optical machine 35 is at least partially disposed in the first accommodating groove 3112, the display window 3113 is used for light emission from the optical machine 35, and the light emission surface of the optical machine 35 corresponds to the position of the display window 3113. The assembly shell 31 in this example is at least partially a hollow structure, wherein the first accommodating groove 3112 can be used to accommodate the optical machine 35, so that the optical machine 35 can be at least partially located inside the assembly shell 31 to improve the safety and stability of the optical machine 35. The display window 3113 is a through hole connected to the first accommodating groove 3112, and is used for light emission from the optical machine 35. The light emission surface of the optical machine 35 is arranged on the same side as the display window 3113, so that the light projected by the optical machine 35 can be emitted through the display window 3113. Optionally, in this example, the optical machine 35 can be partially located inside the display window 3113. In this example, the optical engine 35 can be completely located in the first accommodating groove 3112 to simplify the structure of the assembly shell 31; the optical engine 35 in this example can also be partially located in the first accommodating groove 3112, for example, the optical component 351 and the micro display 3531 of the optical engine 35 are arranged in the first accommodating groove 3112, so as to reduce the thickness of the assembly shell 31. Optionally in this example, the first accommodating groove 3112 can be a groove opened on one of the end faces of the assembly shell 31, and a cover body for closing the groove can be provided on the assembly shell 31, so that the optical engine 35 is limited to a preset position in the assembly shell 31.

[0066] See also Figure 5 and Figure 6 In some examples, the assembly shell 31 includes a first shell 311 and a second shell 312, the first outer surface is located on the first shell 311 and / or the second shell 312, and the second outer surface is located on the first shell 311 and / or the second shell 312. It can be understood that the first outer surface can be located on one of the first shell 311 or the second shell 312, or on both shells at the same time, and the second outer surface can be located on one of the first shell 311 or the second shell 312, or on both shells at the same time; in some embodiments, the first outer surface and the second outer surface can be the outer surface of the assembly shell 31, and corresponding protrusions or grooves can be provided thereon. The first shell 311 has a fixing surface 3111, and a first receiving groove 3112 is provided on the fixing surface 3111, and a display window 3113 is provided on the first shell 311; the second shell 312 is covered on the first shell 311 to close the first receiving groove 3112. In this example, the assembly shell 31 is divided into a first shell 311 and a second shell 312 , wherein the first shell 311 is used to accommodate the optical engine 35 , and the second shell 312 can serve as a cover of the first shell 311 to close the first accommodating groove 3112 of the first shell 311 .

[0067] The fixing surface 3111 is a surface on the first shell 311 facing the second shell 312. The fixing surface 3111 in this example can be a plane or a curved surface, or a combination of a plane and a curved surface. The first receiving groove 3112 is a groove opened on the fixing surface 3111. The display window 3113 is opened on the first shell 311. One end of the display window 3113 is connected to the first receiving groove 3112, and the other end passes through the side surface of the first shell 311 facing away from the second shell 312, so that when the optical machine 35 is installed in the first receiving groove 3112, the light emitting surface of the optical machine 35 can face the outside of the first shell 311.

[0068] In some examples, the display window 3113 may also be opened on the second housing 312, the display window 3113 corresponds to the position of the first accommodating groove 3112, when the second housing 312 is covered on the first housing 311, the display window 3113 may be connected to the first accommodating groove 3112, the light emitting surface of the optical engine 35 is arranged toward the display window 3113, and the light projected by the optical engine 35 may be output through the display window 3113. In this example, the optical engine 35 may be partially embedded in the display window 3113.

[0069] After the second housing 312 is installed on the first housing 311, the second housing 312 closes the first accommodating groove 3112 so that the optical engine 35 is confined in the first housing 311. The first housing 311 and the second housing 312 in this example can be threaded, snap-fitted, or connected in other ways. In some examples, one of the first housing 311 and the second housing 312 is provided with a positioning column 3121, and the other is provided with a positioning hole 3117, and the positioning column 3121 is inserted into the positioning hole 3117 to position the first housing 311 and the second housing 312 relative to each other.

[0070] See also Figure 6 In some examples, the optical machine 35 includes an optical component 351 and a display component 353, the optical component 351 is at least partially embedded in the display window 3113; the display component 353 is at least partially disposed in the first accommodating groove 3112, and is at least partially located on the side of the optical component 351 facing away from the display window 3113; the second shell 312 abuts against the side of the display component 353 facing away from the optical component 351.

[0071] The display component 353 described in this example can be the micro display 3531 described above, and the display component 353 can also include other circuit components. The display component 353 can be used to project light to the optical component 351. The optical component 351 is at least partially embedded in the display window 3113 to facilitate fixing the optical component 351. The display window 3113 can limit the movement of the optical component 351 along the radial direction of the display window 3113, and can also reduce the light leakage of the optical machine 35.

[0072] In this example, the display assembly 353 is at least partially located in the first accommodating groove 3112, so that the display assembly 353 is at least partially confined in the first accommodating groove 3112 to improve the stability of the display assembly 353. The second housing 312 abuts against the side of the display assembly 353 facing away from the optical assembly 351, so as to block the display assembly 353 through the second housing 312, thereby reducing unnecessary displacement of the display assembly 353 and the optical assembly 351. In some examples, a bracket 352 is provided in the first accommodating groove 3112, and the optical assembly 351 can be installed on the bracket 352 to achieve the fixation and position limiting of the optical assembly 351. The bracket 352 in this example can be provided with a through hole coaxial with the display window 3113, and the optical assembly 351 can be plugged into the through hole on the bracket 352 to limit the optical assembly 351 while reducing the light leakage of the optical machine 35.

[0073] In some examples, the display component 353 includes a microdisplay 3531 and an adapter plate 3532, the microdisplay 3531 is disposed in the first accommodating groove 3112 and is located on the side of the optical component 351 facing away from the display window 3113; the second shell 312 abuts against the side of the microdisplay 3531 facing away from the optical component 351; the adapter plate 3532 is connected to the microdisplay 3531 via the first connecting member 3533.

[0074] The micro display 3531 in this example is used to project light to the optical assembly 351. The micro display 3531 may be a light emitting diode panel or a liquid crystal display screen as described above, or may be other micro display 3531 structures. The second housing 312 in this example may abut against the side of the micro display 3531 facing away from the optical assembly 351, so that the micro display 3531 and the optical assembly 351 are kept in a preset position, so as to reduce the vibration and displacement of the micro display 3531 and the optical assembly 351 in the assembly shell 31.

[0075] The adapter plate 3532 in this example can be used to connect the micro display 3531 and the external structure, and the adapter plate 3532 can be a circuit board or other electrical structure. The first connector 3533 is used to connect the adapter plate 3532 and the micro display 3531. The first connector 3533 in this example can be a wire, a flexible circuit board, a metal plating or other structure that can realize the electrical connection between the adapter plate 3532 and the micro display 3531. In some examples, the number of adapter plates 3532 is multiple, and the multiple adapter plates 3532 can be connected to the micro display 3531 respectively. The multiple adapter plates 3532 can be arranged in series or in parallel, and the multiple adapter plates 3532 can also be arranged in series and parallel. The series and parallel mixed arrangement means that some adapter plates 3532 are arranged in series and some adapter plates 3532 are arranged in parallel. When multiple adapter plates 3532 are provided, the multiple adapter plates 3532 can be used to connect the microdisplay 3531 to different electrical devices respectively. For example, some adapter plates 3532 can be used to connect batteries, and some adapter plates 3532 can be used to connect external controllers.

[0076] In this example, by using the adapter plate 3532 to transfer the micro display 3531, it is convenient to set the battery and other electrical appliances required by the optical machine 35 outside the assembly shell 31 to reduce the volume of the near-eye display module 30. The adapter plate 3532 in this example can be fixed in the first accommodating groove 3112, the adapter plate 3532 can also be set at other positions in the assembly shell 31, and the adapter plate 3532 can also be installed on the outside of the assembly shell 31. The first connector 3533 in this example can be inserted into the interior of the assembly shell 31, and the first connector 3533 can also be partially exposed from the assembly shell 31.

[0077] In some examples, a second receiving groove 3114 is further provided on the fixing surface 3111, and the adapter plate 3532 is provided in the second receiving groove 3114. The second receiving groove 3114 can be used to accommodate the adapter plate 3532 so as to embed the adapter plate 3532 in the assembly shell 31. The second receiving groove 3114 in this example can be spaced apart from the first receiving groove 3112, the second receiving groove 3114 can be a groove of the same depth as the first receiving groove 3112, or the second receiving groove 3114 can have a different depth from the first receiving groove 3112. The second receiving groove 3114 and the first receiving groove 3112 in this example can be spaced apart along the length direction of the assembly shell 31. Figure 2The direction 2a shown in the figure is the first direction 2a, and the first accommodating groove 3112 and the second accommodating groove 3114 can be arranged at intervals along the first direction 2a. Since the assembly shell 31 is inserted into the installation cavity 151, the assembly shell 31 itself needs to have a certain length. In this example, the first accommodating groove 3112 and the second accommodating groove 3114 are arranged at intervals along the first direction 2a, which can make full use of the space of the assembly shell 31 in the length direction. In this example, the display window 3113 can be set at the first end of the assembly shell 31 along the first direction 2a, and the first accommodating groove 3112 is arranged corresponding to the position of the display window 3113. Compared with the first accommodating groove 3112, the second accommodating groove 3114 can be arranged closer to the second end of the assembly shell 31 along the first direction 2a, so as to facilitate the lead wire connected to the adapter plate 3532 to be led out from the second end of the assembly shell 31. In this example, the first connector 3533 can be arranged inside the assembly shell 31, and the first connector 3533 can also be led out from the assembly shell 31 and connected to the adapter plate 3532. Optionally in this example, the second accommodating groove 3114 has an opening toward the second shell 312. When the second shell 312 is assembled on the first shell 311, the second shell 312 closes the opening of the second accommodating groove 3114. The second shell 312 can abut against the adapter plate 3532 to limit the displacement of the adapter plate 3532, improve the stability of the adapter plate 3532, and thereby improve the reliability of the connection between the adapter plate 3532 and the micro display 3531.

[0078] In some examples, a third accommodating groove 3115 is further provided on the fixing surface 3111, the first accommodating groove 3112 is connected to the second accommodating groove 3114 through the third accommodating groove 3115, and the first connecting member 3533 is at least partially disposed in the third accommodating groove 3115. The third accommodating groove 3115 in this example is located between the first accommodating groove 3112 and the second accommodating groove 3114, and is used to accommodate the first connecting member 3533, so that the first connecting member 3533 is arranged inside the assembly shell 31. The third accommodating groove 3115 in this example is connected to the first accommodating groove 3112 and the second accommodating groove 3114, so that the first connecting member 3533 can be located inside the assembly shell 31, reducing the exposure of the circuit, which helps to improve the safety of the near-eye display module 30. In some examples, the third receiving groove 3115 has an opening toward the second housing 312. When the second housing 312 is assembled on the first housing 311, the second housing 312 closes the opening of the third receiving groove 3115. Optionally, the second housing 312 abuts against the first connecting member 3533 so that the second housing 312 limits the displacement of the first connecting member 3533, thereby improving the reliability of the connection between the adapter plate 3532 and the micro display 3531.

[0079] See also Figure 7 and Figure 8In some examples, the depth of the third accommodating groove 3115 is not greater than the depth of the first accommodating groove 3112. In this example, the depth of the third accommodating groove 3115 at one end close to the first accommodating groove 3112 can be relatively small, thereby limiting the displacement of the first connecting member 3533 in the depth direction of the third accommodating groove 3115, and facilitating the matching of the height of the first connecting member 3533 with the micro display 3531. When the second housing 312 is assembled on the first housing 311, the second housing 312 is more likely to abut against the first connecting member 3533, thereby limiting the displacement of the first connecting member 3533, and helping to improve the stability of the first connecting member 3533. In this example, along the first direction 2a, the depths of the third accommodating grooves 3115 can be equal or unequal.

[0080] See also Figure 8 In some examples, the depth of the third receiving groove 3115 is not greater than the depth of the second receiving groove 3114. In this example, the depth of the third receiving groove 3115 at one end close to the second receiving groove 3114 can be relatively small, thereby limiting the displacement of the first connecting member 3533 in the depth direction of the third receiving groove 3115, and facilitating the matching of the height of the first connecting member 3533 with the adapter plate 3532. When the second housing 312 is assembled on the first housing 311, the second housing 312 is more likely to abut against the first connecting member 3533, thereby limiting the displacement of the first connecting member 3533 and helping to improve the stability of the first connecting member 3533. In this example, along the first direction 2a, the depths of the third receiving grooves 3115 can be equal or unequal.

[0081] In some examples, the depth of the third accommodating groove 3115 is not greater than the depth of the first accommodating groove 3112 and the second accommodating groove 3114. In this example, the first accommodating groove 3112, the second accommodating groove 3114 and the third accommodating groove 3115 form a stepped structure to limit the position of the corresponding device as needed, so that the corresponding groove matches the thickness of the device, so as to improve the stability of the display component 353 and the optical component 351.

[0082] In some examples, the adapter plate 3532 is disposed in the first receiving groove 3112 and is located on the side of the microdisplay 3531 facing away from the display window 3113, and the second housing 312 abuts against the side of the adapter plate 3532 facing away from the microdisplay 3531. The adapter plate 3532 and the microdisplay 3531 in this example are disposed in the first receiving groove 3112, so that only one groove structure needs to be opened on the first housing 311, which helps to simplify the structure of the first housing 311. In this example, the adapter plate 3532 can be disposed close to the microdisplay 3531, so that the optical component 351, the microdisplay 3531 and the adapter plate 3532 are stacked, and the second housing 312 abuts against the side of the adapter plate 3532 facing away from the microdisplay 3531 to limit the movement of the optical engine 35, thereby reducing the problem of displacement or shaking of the optical engine 35 in the assembly shell 31.

[0083] In some examples, the near-eye display module 30 also includes a second connecting member 3534, which is connected to the adapter plate 3532, for example, electrically connected; a fourth accommodating groove 3116 is also provided on the fixed surface 3111, and one end of the fourth accommodating groove 3116 extends to the adapter plate 3532, and the other end extends to the outer wall of the first shell 311, and the second connecting member 3534 is at least partially embedded in the fourth accommodating groove 3116.

[0084] The second connector 3534 in this example can be a wire, a flexible circuit board, a metal coating or other structure that can electrically connect the adapter board 3532 to other electrical devices. One end of the second connector 3534 is connected to the adapter board 3532, and the other end is exposed to the outside of the assembly shell 31, so as to connect the near-eye display module 30 to the external electrical device. The external electrical device in this example can be a battery, a controller or other electrical structures.

[0085] The fourth receiving groove 3116 in this example is a groove provided on the first housing 311, and the first receiving groove 3112 is used to accommodate the second connecting member 3534. In some examples, the second receiving groove 3114 described in the above example is provided on the first housing 311, one end of the fourth receiving groove 3116 is connected to the second receiving groove 3114, and the other end extends to the outer wall of the first housing 311, so that the adapter plate 3532 in the second receiving groove 3114 can be connected to the second connecting member 3534, for example, electrically connected. In some examples, the adapter plate 3532 is provided in the first receiving groove 3112, one end of the fourth receiving groove 3116 is connected to the first receiving groove 3112, and the other end extends to the outer wall of the first housing 311. In this example, the fourth receiving groove 3116 is optionally open toward the second housing 312. When the second housing 312 is assembled on the first housing 311, the second housing 312 can close the opening of the fourth receiving groove 3116 to improve the sealing of the assembly shell 31. In this example, the second housing 312 can abut against the second connecting member 3534 to reduce the shaking of the second connecting member 3534 and improve the stability of the connection between the second connecting member 3534 and the adapter plate 3532.

[0086] See also Figure 6 In some examples, a protrusion 3122 is provided on the side of the second housing 312 facing the first housing 311, and the protrusion 3122 abuts against the side of the display component 353 facing away from the optical component 351. The protrusion 3122 in this example is provided protrudingly on the surface of the second housing 312, and the protrusion 3122 is used to abut against the side of the display component 353 facing away from the optical component 351, which means that the end surface of the protrusion 3122 facing the first housing 311 can abut against at least one of the micro display 3531 and the adapter plate 3532 to limit the movement of the display component 353, thereby improving the stability of the display component 353.
