Description

Technical Field

[0001] This application relates to the technical field of head-mounted devices, specifically to a head-mounted display mechanism and a head-mounted device. Background Technology

[0002] With the continuous maturation of VR (Virtual Reality) and MR (Mixed Reality) technologies, more and more people are using VR or MR-enabled head-mounted devices for work, entertainment, or social interaction, and people's demands for these devices are also increasing. Currently, most head-mounted devices display images through onboard display modules, and considering the differences in interpupillary distance among different users, the display modules are generally movable to allow users to adjust their position. However, the sliding mechanism of existing head-mounted device display modules typically uses a gear and rack transmission structure, which is highly homogenized and lacks innovation. Therefore, providing a new adjustment mechanism has become a major research direction for industry professionals. Summary of the Invention

The pushing block is slidably connected to the movable block, and its sliding direction is perpendicular to both the reference direction and the sliding direction of the movable block, and is located between the two display components. The first connecting rod is hinged to the pushing block and one display component, and the... The rotation axis of the first link is perpendicular to the sliding direction of the display component hinged to the first link; the second link is hinged to the push block and another display component, and the rotation axis of the second link is perpendicular to the sliding direction of the display component hinged to the second link; wherein, when the movable block drives the push block to slide, the push block can push the first link and the second link to swing, and slide relative to the movable block under the action of the first link and the second link, and the first link and the second link can push the two display components to slide away from the push block.

[0004] In another aspect, this application provides a head-mounted device, which includes a head circumference mechanism and the aforementioned head-mounted display mechanism, wherein the head circumference mechanism is connected to the head-mounted display mechanism and forms a head-mounted space.

Under the action of the first and second links, the push block can slide relative to the movable block, allowing the two display components hinged to the first and second links to slide under their push. With this configuration, the movable block can be electrically or manually driven to slide the two display components, thereby adjusting their relative positions. Attached Figure Description

The head-mounted device can be configured to transmit data to and receive data from an external processing device via a signal connection, which can be a wired connection, a wireless connection, or a combination thereof. However, in other cases, the head-mounted device can be used as a standalone device, i.e., data processing can be performed within the head-mounted device itself. The signal 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, a personal computer, a tablet computer, a smartphone, or other types of processing devices. The signal connection can be, for example, a Universal Serial Bus (USB) connection, a Wi-Fi connection, a Bluetooth or Bluetooth Low Energy (BLE) connection, an Ethernet connection, a cable connection, a DSL connection, a cellular connection (e.g., 3G, LTE / 4G, or 5G), 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.

[0025] 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.

[0026] 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.

[0027] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the head-mounted device 10 provided in the embodiments of this application. Figure 2 yes Figure 1 A schematic diagram of the structure of the head-mounted display mechanism 100. Figure 3 yes Figure 2 A schematic diagram of the connection structure between the rear shell 112 and the display component 120. Figure 4 yes Figure 3 Another schematic diagram of the connection structure between the middle rear shell 112 and the display component 120.

[0028] The head-mounted device 10 provided in this application embodiment can be worn on a user's head and has the function of displaying images in front of the user's eyes, such as virtual reality or mixed reality. Figure 1 As shown, the head-mounted device 10 includes a head-mounted display mechanism 100 and a head circumference mechanism 200. The head-mounted display mechanism 100 is connected to the head circumference mechanism 200, which also encloses a head-mounted space 300 for the user to wear. The user can place the head-mounted display mechanism 100 in front of their eyes through the head circumference mechanism 200, allowing the head-mounted display mechanism 100 to project an image in front of the user's eyes, thus enabling virtual reality or augmented reality functions. Furthermore, the head-mounted display mechanism 100 can adjust the imaging position according to the user's interpupillary distance, allowing users with different interpupillary distances to use the head-mounted display mechanism 10, thereby improving the versatility of the head-mounted device 10.

[0029] The head-mounted display 100 can be worn in front of the user's eyes and used for imaging to achieve virtual reality functionality. For example... Figures 1 to 2 As shown, the head-mounted display mechanism 100 includes a housing assembly 110, a display assembly 120, a blocking assembly 130, and an adjustment assembly 140. The housing assembly 110 can be used to mount various functional components required for the head-mounted device 10 and can be connected to a head circumference mechanism 200, allowing the user to wear the head-mounted display mechanism 100 in front of their eyes via the head circumference mechanism 200. The display assembly 120 is slidably disposed on the housing assembly 110 and can be used for imaging, enabling adjustable imaging position of the head-mounted display mechanism 100. The blocking assembly 130 is disposed on the housing assembly 110 and can be displaced as the display assembly 120 slides. The blocking assembly 130 also blocks the gap between the display assembly 120 and the housing assembly 110 to prevent the structure installed within the housing assembly 110 from being exposed, thereby improving the appearance of the head-mounted display mechanism 100. The adjustment component 140 is disposed inside the housing component 110 and is slidably connected to the display component 120, so that the display component 120 can be slidably disposed on the housing component 110. The adjustment component 140 can also control the sliding of the display component 120 to adjust the position of the display component 120 on the housing component 110.

[0030] For example, the housing assembly 110 is connected to the head circumference mechanism 200 and can be worn in front of the user's eyes through the head circumference mechanism 200. The housing assembly 110 also has a receiving space to accommodate various functional components required for the head-mounted device 10, such as cameras, circuit boards, laser emitters, inertial sensors, and antennas, etc. Figure 2As shown, the housing assembly 110 may include a front housing 111 and a rear housing 112. The front housing 111 may cover the rear housing 112 and be located on the side of the rear housing 112 away from the user's head. The front housing 111 and the rear housing 112 may also jointly form the aforementioned receiving space to accommodate the aforementioned various functional devices.

[0031] The housing assembly 110 may also have a mounting hole 1101 communicating with the receiving space and the outside of the housing assembly 110. This mounting hole 1101 can be used to mount a display assembly 120, allowing the display assembly 120 to not only be electrically connected to functional devices within the receiving space through the mounting hole 1101, but also to be exposed outside the housing assembly 110 through the mounting hole 1101, so that the user can view the image displayed by the display assembly 120. For example, a mounting hole 1101 communicating with the receiving space may be provided on the side of the rear housing 112 opposite to the front housing 111. The mounting hole 1101 may be larger than the size of the display assembly 120 only in the sliding direction, while its size in other directions matches the size of the display assembly 120, thus limiting the sliding of the display assembly 120 in directions other than the sliding direction. Furthermore, there may be two mounting holes 1101, and two display assemblies 120 may be mounted in each of the two mounting holes 1101. In this embodiment, the two display components 120 can slide in the two mounting holes 1101 respectively in a direction that is close to or far from each other, so that the two display components 120 can adjust the imaging position according to the interpupillary distance between the user's left and right eyes, so that different users can use the head-mounted display mechanism 100.

[0032] Optionally, the housing assembly 110 may further include a flexible pad 113. The flexible pad 113 is connected to the side of the rear housing 112 opposite to the front housing 111, and when the user wears the head-mounted device 10, the flexible pad 113 can contact the user's face to cushion the pressure on the user's face, thereby improving the user's wearing comfort. Simultaneously, the flexible pad 113 can also form a light-shielding channel between the rear housing 112 and the user's face to reduce interference from external light on the image light emitted by the display assembly 120, thereby improving the display effect of the display assembly 120. Of course, in some embodiments, the design of the flexible pad 113 may be omitted.

[0033] Optionally, the housing assembly 110 can also be rotatably connected to the head circumference mechanism 200 and can be flipped from the user's face toward the top of the user's head, allowing the user to view the real-world environment without removing the head-mounted display mechanism 10, thereby improving the user's convenience in using the head-mounted device 10. For example, a connecting shell 114 can be provided on the side of the rear shell 112 near the top of the user's head. Figure 1(As shown), the connecting shell 114 can be fitted onto the head circumference mechanism 200 and can rotate relative to the head circumference mechanism 200 to achieve a rotatable connection between the shell assembly 110 and the head circumference mechanism 200. Simultaneously, considering the requirement for the shell assembly 110 to rotate and hover, a damping element can also be provided inside the connecting shell 114. This damping element can abut against both the connecting shell 114 and the head circumference mechanism 200, and can generate a damping force when the connecting shell 114 rotates, thereby utilizing the damping force to achieve the rotation and hovering of the shell assembly 110. Of course, the shell assembly 110 can also be fixedly connected to the head circumference mechanism 200; this embodiment does not limit this.

[0034] It is understood that the foregoing embodiments regarding the housing assembly 110 are merely illustrative examples, and the specific shape and structure of the housing assembly 110 can be adaptively adjusted according to the design requirements of the head-mounted device 10. This embodiment does not limit this. Furthermore, 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 relationships and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, 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.

[0035] The display component 120 is disposed on the housing component 110 and can be used for imaging to realize virtual reality or mixed reality functions. The display component 120 is also slidably connected to the adjustment component 140, allowing the display component 120 to adjust its imaging position according to the user's interpupillary distance. Figures 2 to 4 As shown, there can be two display components 120, which can be a first display component 121 and a second display component 122, respectively, to match the user's left and right eyes. The first display component 121 and the second display component 122 can be respectively disposed within two mounting holes 1101 and can slide towards or away from each other, allowing the first display component 121 and the second display component 122 to adjust their imaging positions according to the user's interpupillary distance, facilitating use of the head-mounted display mechanism 100 by different users. In this embodiment, the first display component 121 and the second display component 122 can slide synchronously towards or away from each other.

[0036] Optionally, the display component 120 may include an optical engine and a display lens (such as a waveguide), and the light emitted by the optical engine can be transmitted to the display lens for imaging, thereby realizing virtual reality or mixed reality functions in front of the user's eyes. Of course, in addition to the optical engine and display lens, the display component 120 may also include other necessary structural components, such as a housing, flexible circuit board, and light-shielding foam, etc., which are not limited in this embodiment. Of course, in addition to using an optical engine and display lens for imaging, the display component 120 may also be other devices with imaging functions (such as a monitor, etc.), as long as the display component 120 can form an image in front of the user's eyes, which is not limited in this embodiment.

[0037] Because the size of the mounting hole 1101 in the sliding direction of the display component 120 is larger than the size of the display component 120, a cavity 400 (equivalent to the aforementioned gap) is formed between the display component 120 and the rear shell 112, connecting the interior of the shell component 110 and the accommodating space. This allows the user to directly see the internal structure of the shell component 110 through the cavity 400, greatly affecting the appearance of the head-mounted display mechanism 100. Furthermore, the presence of the cavity 400 makes it easier for foreign objects such as dust, water stains, and sweat to enter the shell component 110, increasing the probability of malfunction and reducing the reliability of the head-mounted display mechanism 100.

[0038] Based on this, some solutions involve providing a skirt structure 123 overlapping the rear shell 112 on the periphery of the outer casing of the display component 120, so as to use the skirt structure 123 to cover the aforementioned opening 400. Specifically, to ensure that the skirt structure 123 is positioned at the minimum interpupillary distance between the first display component 121 and the second display component 122 (… Figure 3 (shown) and maximum interpupillary distance ( Figure 4 As shown, the skirt structure 123 can cover the hole 400. The skirt structure 123 often needs to be designed with a large area to ensure that the skirt structure 123 can completely cover the hole 400, thereby avoiding the exposure of the internal structure of the housing assembly 110.

[0039] However, since the skirt structure 123 slides along with the display component 120, the housing component 110 needs not only to design an installation space to accommodate the skirt structure 123, but also to design sufficient sliding space to avoid the sliding of the skirt structure 123. This undoubtedly results in the skirt structure 123 occupying a significant portion of the internal space of the housing component 110, thus limiting the spatial layout of the housing component 110. Simultaneously, to avoid interference between the skirt structures 123 of the first display component 121 and the second display component 122, a larger spacing needs to be designed between the first display component 121 and the second display component 122. Consequently, the interpupillary distance adjustment range of the first display component 121 and the second display component 122 cannot cover people with smaller interpupillary distances, reducing the versatility of the head-mounted device 10.

[0040] To address the aforementioned technical problems, this embodiment of the application provides a shielding component 130 on the housing assembly 110. This shielding component 130 effectively blocks the gap between the display assembly 120 and the rear shell 112, thereby improving both the airtightness and aesthetics of the head-mounted display mechanism 100. Furthermore, compared to the aforementioned skirt structure 123, the shielding component 130 of this embodiment offers advantages such as simple structure, small size, light weight, and high layout flexibility. This not only reduces the spatial limitations imposed by the shielding component 130 on the housing assembly 110, thus expanding the minimum interpupillary distance adjustment range of the display assembly 120, but also reduces the overall weight of the head-mounted display mechanism 100.

[0041] It is understood that the aforementioned minimum interpupillary distance position refers to the limit position that the first display component 121 and the second display component 122 can slide to in the direction of approaching each other, at which point the distance between the first display component 121 and the second display component 122 is the smallest. The maximum interpupillary distance position refers to the limit position that the first display component 121 and the second display component 122 can slide to in the direction of away from each other, at which point the distance between the first display component 121 and the second display component 122 is the largest.

[0042] Please see Figures 5 to 7 , Figure 5 yes Figure 2 A structural schematic diagram of the central head-mounted display mechanism 100. Figure 6 yes Figure 5 An exploded view of the central head-mounted display mechanism 100. Figure 7 yes Figure 5 A schematic diagram of the cross-sectional structure of the central head-mounted display mechanism 100 along section V-V.

[0043] The shielding component 130 is disposed within the housing component 110 and connected to the display component 120. It can slide under the influence of the display component 120 to shield the gap between the display component 120 and the housing component 110. Figures 5 to 8As shown, the shielding assembly 130 may include a fixed bracket 131, a rigid member 132, and a flexible member 133. Both the fixed bracket 131 and the rigid member 132 are disposed within the housing assembly 110, with the rigid member 132 located on one side of the fixed bracket 131 and covering the mounting hole 1101. The rigid member 132 also supports the display assembly 120 and is capable of moving with the display assembly 120 in directions away from or towards the fixed bracket 131. The flexible member 133 is connected to the rigid member 132 and housed within the space on the fixed bracket 131. When the rigid member 132 moves away from the fixed bracket 131, the flexible member 133 can extend from the fixed bracket 131 under the influence of the rigid member 132 to shield the gap between the rigid member 132 and the fixed bracket 131.

[0044] For example, when the display component 120 is in the minimum interpupillary distance position, the gap between the display component 120 and the rear housing 112, that is, between the display component 120 and the inner wall of the mounting hole 1101, is mainly distributed on the opposite sides of the display component 120 near and away from the fixing bracket 131. At this time, since the rigid member 132 is covered on the mounting hole 1101, the rigid member 132 can block the gaps on the opposite sides of the display component 120. When the display component 120 is in the maximum interpupillary distance position, since the display component 120 causes the rigid member 132 to be displaced in the direction away from the fixing bracket 131, the gap on the side of the display component 120 near the fixing bracket 131 will increase, causing the rigid member 132 to be unable to block the gap on the side of the display component 120 near the fixing bracket 131. At this time, in order to block the gap on the side of the display component 120 near the fixed bracket 131, the flexible member 133 housed on the fixed bracket 131 can extend from the fixed bracket 131 under the action of the rigid member 132 to block the gap formed by the displacement of the rigid member 132 and the spaced arrangement with the fixed bracket 131. At the same time, since the display component 120 is supported on the rigid member 132 and the fixed bracket 131 is located inside the housing assembly 110, when the flexible member 133 blocks the gap between the rigid member 132 and the fixed bracket 131, the flexible member 133 can also block the gap on the side of the display component 120 near the fixed bracket 131.

[0045] Optionally, when the display component 120 is in the minimum interpupillary distance position, the rigid member 132 may only block the gap on the side of the display component 120 away from the fixed bracket 131, while the gap on the side of the display component 120 close to the fixed bracket 131 may be blocked by the flexible member 133 connecting a portion of the rigid member 132.

[0046] With the above configuration, regardless of the position of the display component 120, the rigid component 132 and the flexible component 133 can cooperate to cover the gap between the display component 120 and the rear shell 112, thereby preventing the structure installed inside the shell assembly 110 from being exposed and improving the appearance of the head-mounted display mechanism 100. At the same time, since the flexible component 133 is housed on the fixed bracket 131, compared with the aforementioned skirt structure 123 (rigid structure), the flexible component 133 has the advantages of small size and light weight. Moreover, due to its flexibility, its arrangement on the fixed bracket 131 is more flexible. It can not only reduce the space occupied by the covering component 130 on the shell assembly 110, but also expand the coverage range of the minimum interpupillary distance of the display component 120, thereby reducing the impact of the covering component 130 on the spatial layout of the shell assembly 110 and improving the versatility of the head-mounted display mechanism 100.

[0047] Please combine Figure 7 See Figures 8 to 11 , Figure 8 yes Figure 6 A schematic diagram of the connection structure between the rigid component 132 and the flexible component 133. Figure 9 yes Figure 7 A magnified view of a portion of point A in the diagram. Figure 10 yes Figure 5 A magnified view of a portion of point B in the diagram. Figure 11 yes Figure 7 Another enlarged view of point A in the middle.

[0048] For example, the rigid member 132 is slidably disposed within the housing assembly 110 and carries the display assembly 120, and is capable of sliding with the display assembly 120 in directions toward or away from the fixed bracket 131. Figures 7 to 8 As shown, the rigid member 132 is located inside the housing assembly 110 and covers the mounting hole 1101. The size of the rigid member 132 is equal to or slightly larger than the size of the mounting hole 1101, so that the rigid member 132 can block the gap between the display assembly 120 and the inner wall of the mounting hole 1101. Simultaneously, the rigid member 132 can also be arranged around the periphery of the display assembly 120 to form a clearance hole 1301 to avoid the display assembly 120. Figure 6 (as shown), so that the display component 120 can pass through the clearance hole 1301 through the rigid member 132, so that the display component 120 can pass through the rigid member 132 to make electrical connection with other devices in the housing assembly 110.

[0049] Optionally, in addition to being slidably disposed within the housing assembly 110 via the display component 120, the rigid member 132 can also be slidably connected to the housing assembly 110 independently. That is, the rigid member 132 can also be slidably connected to the rear housing 112 or the front housing 111 via structural components such as sliding shafts, sliding rails, or sliding tracks. It is only necessary for the rigid member 132 to be able to slide with the display component 120 in the direction of approaching or moving away from the fixed bracket 131. This embodiment does not limit this.

[0050] Optionally, the rigid member 132 can be made of rigid plastic to further reduce the weight of the shielding assembly 130 while ensuring that the rigid member 132 has a certain structural strength. Of course, the material of the rigid member 132 is not limited to this, and the specific material of the rigid member 132 can also be adapted according to design requirements (such as appearance requirements or strength requirements). This embodiment does not limit this.

[0051] Furthermore, the number of rigid members 132 can also be two, and the two rigid members 132 can be a first rigid member 1321 and a second rigid member 1322, respectively, to support the connection of the first display component 121 and the second display component 122. The first rigid member 1321 and the second rigid member 1322 are located on opposite sides of the fixing bracket 131, and the first rigid member 1321 and the second rigid member 1322 can respectively cover the two mounting holes 1101 to block the gaps between the first display component 121 and the rear shell 112, and between the second display component 122 and the rear shell 112, at the minimum interpupillary distance position. In this embodiment, the first rigid member 1321 and the second rigid member 1322 can be symmetrically arranged, and the first rigid member 1321 and the second rigid member 1322 can simultaneously move towards or away from the fixing bracket 131.

[0052] With the above configuration, since the rigid member 132 does not need to block the gap on the side of the display component 120 near the fixed bracket 131 after displacing away from the fixed bracket 131, the area of ​​the rigid member 132 between the display component 120 and the fixed bracket 131 can be designed to be smaller. It only needs to ensure that it can block the gap on the side of the display component 120 near the fixed bracket 131 at the minimum interpupillary distance position, thereby reducing the space occupied by the rigid member 132 on the housing component 110. At the same time, the smaller rigid member 132 can also have a larger sliding stroke under the same sliding space, so that the distance that the display component 120 slides toward the fixed bracket 131 can be increased, thereby expanding the coverage area of ​​the display component 120 at the minimum interpupillary distance position and improving the versatility of the head-mounted display mechanism 100. In addition, the smaller rigid member 132 can also reduce the weight of the blocking component 130, which is beneficial to improving the comfort of the user wearing the head-mounted device 10.

[0053] like Figure 7 and Figures 9 to 10 As shown, the flexible member 133 is connected to the rigid member 132 and housed on the fixed bracket 131. When the rigid member 132 moves away from the fixed bracket 131, the flexible member 133 can extend from the fixed bracket 131 under the pull of the rigid member 132 to block the gap between the display component 120 and the fixed bracket 131. For example, the flexible member 133 can be housed in the space on the fixed bracket 131 in a preset manner (folding or rolling, etc.). When the rigid member 132 moves away from the fixed bracket 131, the flexible member 133 can extend from the fixed bracket 131 under the pull of the rigid member 132 to block the gap on the side of the display component 120 near the fixed bracket 131. Alternatively, the flexible member 133 can be fixedly connected to the fixed bracket 131. When the rigid member 132 moves away from the fixed bracket 131, the flexible member 133 can undergo elastic deformation and stretch under the pull of the rigid member 132, allowing the flexible member 133 to still extend from the fixed bracket 131 to block the gap on the side of the display component 120 near the fixed bracket 131. In this embodiment, the flexible member 133 can be made of easily deformable materials with a certain tensile strength, such as PET, fabric, silicone, PI, and Teflon.

[0054] Optionally, when the rigid member 132 displaces towards the fixed support 131, the flexible member 133 can also retract onto the fixed support 131 simultaneously to maintain the flatness of the flexible member 133 during the expansion and contraction process, thereby reducing the probability of wrinkles appearing on the flexible member 133. That is, when the rigid member 132 displaces towards the fixed support 131, the flexible member 133 can also retract onto the fixed support 131 simultaneously with the displacement of the rigid member 132, rather than retracting onto the fixed support 131 under the pushing force of the rigid member 132. For example, the flexible member 133 can retract onto the fixed support 131 under the action of the force generated by the corresponding driving structure. Alternatively, the flexible member 133 can retract onto the fixed support 131 under its own elastic force. Of course, in some embodiments, if the problem of wrinkles is not considered, the flexible member 133 can also retract onto the fixed support 131 under the pushing force of the rigid member 132.

[0055] Furthermore, the number of flexible members 133 can also be two, and the two flexible members 133 are respectively the first flexible member 1331 and the second flexible member 1332. The first flexible member 1331 can be connected to the first rigid member 1321, and the second flexible member 1332 can be connected to the second rigid member 1322. Both the first flexible member 1331 and the second flexible member 1332 can be housed on the fixed bracket 131. Simultaneously, when the first rigid member 1321 and the second rigid member 1322 both move away from the fixed bracket 131, the first flexible member 1331 and the second flexible member 1332 can extend out of the fixed bracket 131 under the pull of the first rigid member 1321 and the second rigid member 1322, respectively, to block the gaps on the side of the first display component 121 near the fixed bracket 131 and the gaps on the side of the second display component 122 near the fixed bracket 131, respectively. Furthermore, when both the first rigid member 1321 and the second rigid member 1322 displace toward the fixed bracket 131, the first flexible member 1331 can retract onto the fixed bracket 131 synchronously with the first rigid member 1321, and the second flexible member 1332 can retract onto the fixed bracket 131 synchronously with the second rigid member 1322, thereby maintaining the flatness of the first flexible member 1331 and the second flexible member 1332 during the extension and retraction process. In this embodiment, the first flexible member 1331 and the second flexible member 1332 can extend or retract onto the fixed bracket 131 synchronously.

[0056] Optionally, the flexible part 133 can also have an appearance design such as texture, color and pattern in a portion of the gap near the fixed bracket 131 of the display component 120, so as to further enhance the appearance of the head-mounted display mechanism 100 while covering the gap.

[0057] With the above configuration, when the display component 120 slides from the minimum interpupillary distance position to the maximum interpupillary distance position, the flexible component 133 can extend out of the fixed bracket 131 to cover the gap on the side of the display component 120 near the fixed bracket 131, thereby preventing the internal structure of the housing component 110 from being exposed. At the same time, compared with the aforementioned skirt structure 123, the flexible component 133 has the advantages of small size and light weight, and its flexible layout on the fixed bracket 131 is also more flexible. This not only helps to reduce the space occupied by the covering component 130 on the housing component 110, but also expands the coverage range of the minimum interpupillary distance of the display component 120, thereby improving the versatility of the head-mounted display mechanism 100.

[0058] The following describes in detail the arrangement of the flexible component 133 on the fixed bracket 131. It is understood that, in addition to the following embodiments, there are many other ways in which the flexible component 133 can be arranged on the fixed bracket 131, which will not be listed here.

[0059] Exemplarily, the first flexible member 1331 can pass through the fixed bracket 131 in a direction perpendicular to the displacement direction of the first rigid member 1321. After passing through the fixed bracket 131, the first flexible member 1331 is bent away from the fixed bracket 131 towards the first rigid member 1321, and then connected to the second display component 122. Simultaneously, the second flexible member 1332 can pass through the fixed bracket 131 in a direction perpendicular to the displacement direction of the second rigid member 1322. After passing through the fixed bracket 131, the second flexible member 1332 is bent away from the fixed bracket 131 towards the second rigid member 1322, and then connected to the first display component 121. In this embodiment, the fixed bracket 131 has a receiving groove 1311 for the first flexible member 1331 and the second flexible member 1332 to pass through, and this receiving groove 1311 can penetrate both sides of the fixed bracket 131 parallel to the displacement direction of the first rigid member 1321.

[0060] Furthermore, in order to connect to the first flexible member 1331 and the second flexible member 1332 respectively, the first display assembly 121 and the second display assembly 122 are also provided with a first connecting block 1211 and a second connecting block 1221 extending toward each other. Figure 10 As shown, the first connecting block 1211 can extend to the side where the second display component 122 is located, and the end of the first connecting block 1211 away from the first display component 121 can be connected to the bent second flexible member 1332 (such as by bonding, snap-fit ​​connection, or welding). Simultaneously, the second connecting block 1221 can extend to the side where the first display component 121 is located, and the end of the second connecting block 1221 away from the second display component 122 can be connected to the bent first flexible member 1331.

[0061] Specifically, the first flexible member 1331 may include a first connecting portion 1331a, a first blocking portion 1331b, and a first extension portion 1331c. The first connecting portion 1331a can be connected to the first rigid member 1321 and is located on the side of the fixed bracket 131 parallel to the displacement direction of the first rigid member 1321. The first blocking portion 1331b is connected to the first connecting portion 1331a and passes through the fixed bracket 131 along the receiving groove 1311. When the first rigid member 1321 moves away from the fixed bracket 131, the first blocking portion 1331b can extend out of the receiving groove 1311 under the pull of the first rigid member 1321 to block the gap of the first display assembly 121 near the fixed bracket 131. The first extension portion 1331c is located on the side of the fixed bracket 131 opposite to the first connecting portion 1331a and is connected to the first blocking portion 1331b. Meanwhile, the first extension 1331c extends toward the first rigid member 1321 away from the fixed bracket 131, and is connected to the end of the second connecting block 1221 after extension.

[0062] The second flexible member 1332 may include a second connecting portion 1332a, a second blocking portion 1332b, and a second extension portion 1332c. The second connecting portion 1332a can be connected to the second rigid member 1322 and is located on the same side of the fixed bracket 131 as the first connecting portion 1331a. The second blocking portion 1332b is connected to the second connecting portion 1332a and passes through the fixed bracket 131 along the receiving groove 1311. When the second rigid member 1322 moves away from the fixed bracket 131, the second blocking portion 1332b can extend out of the fixed bracket 131 under the pull of the second rigid member 1322 to block the gap of the second display assembly 122 near the fixed bracket 131. The second extension portion 1332c is located on the side of the fixed bracket 131 opposite to the second connecting portion 1332a and is connected to the second blocking portion 1332b. Meanwhile, the second extension 1332c extends toward the second rigid member 1322 away from the fixed bracket 131, and is connected to the end of the first connecting block 1211 after extension.

[0063] With the above configuration, when the first rigid member 1321 moves away from the fixed bracket 131 along with the first display assembly 121, the first rigid member 1321 can pull the first connecting part 1331a away from the fixed bracket 131, and the first blocking part 1331b can extend out from the receiving groove 1311 under the pull of the first connecting part 1331a to block the gap on the side of the first display assembly 121 near the fixed bracket 131. At the same time, the first extension part 1331c can be driven by the first blocking part 1331b to pull the second display assembly 122 away from the fixed bracket 131 through the second connecting block 1221, so that the second rigid member 1322 can also move away from the fixed bracket 131 along with the second display assembly 122. Similarly, the second rigid member 1322 will also pull the second flexible member 1332 to slide off the fixed bracket 131, and the second flexible member 1332 can also pull the first display component 121 to slide away from the fixed bracket 131 through the first connecting block 1211, so as to achieve synchronous displacement of the first rigid member 1321 and the second rigid member 1322 away from the fixed bracket 131.

[0064] When the first rigid member 1321 moves toward the fixed bracket 131 along with the first display assembly 121, the first display assembly 121 can pull the second extension 1332c away from the fixed bracket 131 via the first connecting block 1211. The second blocking part 1332b can then retract into the receiving groove 1311 under the pull of the second extension 1332c, and pull the second rigid member 1322 toward the fixed bracket 131 via the second connecting part 1332a. Similarly, when the second rigid member 1322 moves toward the fixed bracket 131, the second display assembly 122 can also pull the first flexible member 1331 away from the fixed bracket 131 via the second connecting block 1221, and the first flexible member 1331 will also pull the first rigid member 1321 toward the fixed bracket 131, so as to achieve synchronous displacement of the first rigid member 1321 and the second rigid member 1322 toward the fixed bracket 131.

[0065] Based on this, not only can the first rigid member 1321 and the second rigid member 1322 be synchronously displaced in the direction away from or near the fixed bracket 131, but also when the first rigid member 1321 and the second rigid member 1322 are displaced in the direction near the fixed bracket 131, the first display component 121 and the second display component 122 can respectively pull the second flexible member 1332 and the first flexible member 1331, so that the first flexible member 1331 and the second flexible member 1332 can be synchronously retracted to the fixed bracket 131 along with the displacement of the first rigid member 1321 and the second rigid member 1322, so as to maintain the flatness of the first flexible member 1331 and the second flexible member 1332 during the extension and retraction process and reduce the probability of wrinkles appearing in the first flexible member 1331 and the second flexible member 1332.

[0066] Optionally, the first connecting portion 1331a can be fitted to the first rigid member 1321 in the thickness direction (e.g., by adhesive bonding), and the thickness direction of the first rigid member 1321 can be perpendicular to the displacement direction of the first rigid member 1321. Simultaneously, the shape of the orthographic projection of the first connecting portion 1331a onto the first rigid member 1321 can match that of the first rigid member 1321 to increase the contact area between the first connecting portion 1331a and the first rigid member 1321, thereby improving the bonding stability between the two. Furthermore, the connection method of the second connecting portion 1332a and the second rigid member 1322 can be the same as or similar to the connection method of the first connecting portion 1331a and the first rigid member 1321, which will not be elaborated upon in this embodiment.

[0067] Optionally, the first display component 121 and the second rigid member 1322 can also jointly tighten the second flexible member 1332, and the second display component 122 and the first rigid member 1321 can also jointly tighten the first flexible member 1331, so that the first flexible member 1331 and the second flexible member 1332 can be tightly attached to the fixed bracket 131, so as to further maintain the flatness of the first flexible member 1331 and the second flexible member 1332 during the extension and contraction process, thereby reducing the probability of wrinkles appearing in the first flexible member 1331 and the second flexible member 1332.

[0068] In addition to the embodiments described above, the flexible element 133 can also be arranged on the fixed bracket 131 by winding. For example... Figure 11As shown, the shielding assembly 130 may further include: a rotating shaft 134 disposed on the fixed bracket 131, and a driving member 135 connected to the rotating shaft 134. The flexible member 133 can be wound around the rotating shaft 134, allowing it to be housed on the fixed bracket 131. Simultaneously, when the rigid member 132 displaces away from the fixed bracket 131, the rigid member 132 can pull the flexible member 133 to extend from the fixed bracket 131, and the flexible member 133 can pull the rotating shaft 134 to rotate. When the rigid member 132 displaces towards the fixed bracket 131, the driving member 135 can generate a force to drive the rotating shaft 134 to rotate in the opposite direction, pulling the flexible member 133 back onto the rotating shaft 134, so that the flexible member 133 can retract synchronously to the fixed bracket 131 along with the displacement of the rigid member 132, thereby maintaining the flatness of the flexible member 133 during the extension and retraction process. In this embodiment, the driving component 135 can be a torsion spring sleeved on the rotating shaft 134, or a drive motor connected to the rotating shaft 134. In this embodiment, when there are two flexible components 133, the fixed bracket 131 can also be provided with two rotating shafts 134, and the first flexible component 1331 and the second flexible component 1332 can be wound around the two rotating shafts 134 respectively.

[0069] Please see Figures 12 to 14 , Figure 12 yes Figure 1 A schematic diagram of the connection structure between the two display components 120 and the adjustment component 140. Figure 13 yes Figure 12 A schematic diagram of the connection structure between the two display components 120 and the slider 147. Figure 14 yes Figure 12 A schematic diagram of the connection structure between the moving block 142 and the pushing block 143.

[0070] The adjustment component 140 is disposed within the housing assembly 110 and slidably connected to the display component 120. The adjustment component 140 can control the sliding of the display component 120 to adjust its position on the housing assembly 110. Figure 12As shown, the adjustment assembly 140 may include: a mounting bracket 141, a movable block 142, a pushing block 143, a swing rod 144, a first connecting rod 145, and a second connecting rod 146. The mounting bracket 141 is disposed within the housing assembly 110 and is slidably connected to the two display assemblies 120, with the sliding directions of the two display assemblies 120 on the mounting bracket 141 being parallel. The movable block 142 is slidably connected to the mounting bracket 141, and the sliding direction of the movable block 142 is perpendicular to the sliding direction of the display assemblies 120. The pushing block 143 is slidably connected to the movable block 142 and hinged to the swing rod 144, with the sliding direction of the pushing block 143 being parallel to the sliding direction of the display assemblies 120. The swing arm 144 is rotatably connected to the mounting bracket 141, and the two ends of the swing arm 144 can rotate relative to the mounting bracket 141 and are respectively hinged to the first link 145 and the second link 146. The first link 145 and the second link 146 are also respectively hinged to the two display components 120 (that is, the aforementioned first display component 121 and the second display component 122).

[0071] Furthermore, when the movable block 142 drives the push block 143 to slide closer to the swing rod 144, the push block 143 can push the opposite ends of the swing rod 144 to rotate relative to the mounting bracket 141. In order not to affect the rotation of the swing rod 144, the push block 143 can also slide relative to the movable block 142 as the swing rod 144 rotates. At the same time, the opposite ends of the swing rod 144 can respectively drive the first link 145 and the second link 146 to swing, and the first link 145 and the second link 146 can also respectively push the first display component 121 and the second display component 122 to slide away from the swing rod 144, that is, away from each other, so that the distance between the first display component 121 and the second display component 122 increases, thereby adjusting the first display component 121 and the second display component 122 from the minimum interpupillary distance position to the maximum interpupillary distance position.

[0072] Similarly, when the movable block 142 drives the push block 143 to slide away from the swing rod 144, the push block 143 can drive the opposite ends of the swing rod 144 to rotate in opposite directions, and can slide in opposite directions relative to the movable block 142 under the action of the swing rod 144. At the same time, the opposite ends of the swing rod 144 can respectively drive the first link 145 and the second link 146 to swing in opposite directions, and the first link 145 and the second link 146 can also respectively drive the first display component 121 and the second display component 122 to slide closer to the swing rod 144, that is, closer to each other, so that the distance between the first display component 121 and the second display component 122 is reduced, so as to adjust the first display component 121 and the second display component 122 from the maximum interpupillary distance position to the minimum interpupillary distance position. With the above settings, the first display component 121 and the second display component 122 can be driven to slide in a direction closer to or further away from each other by the movable block 142, so as to adjust the relative position of the first display component 121 and the second display component 122, so that the head-mounted display mechanism 100 can match the interpupillary distance between the left and right eyes of different users, thereby improving the versatility of the head-mounted display mechanism 100.

[0073] For example, the mounting bracket 141 is disposed within the housing assembly 110, that is, within the receiving space, and the mounting bracket 141 can be fixed to the front housing 111 or the rear housing 112 by means of screw connection, snap-fit, or adhesive. Figure 12 As shown, the mounting bracket 141 can be rectangular in shape and includes two opposing and spaced-apart long sides 1411 and two opposing and spaced-apart short sides 1412, which are perpendicularly connected to the two long sides 1411 respectively. The two long sides 1411 and the two short sides 1412 can jointly form a sliding space 1401. The sliding space 1411 can accommodate the first display component 121 and the second display component 122, and the first display component 121 and the second display component 122 can slide within the sliding space 1401. In this embodiment, the sliding direction of the first display component 121 and the second display component 122 can be perpendicular to the short side 1412, and the sliding direction of the movable block 142 can be perpendicular to the long side 1411, so that the sliding direction of the display component 120 can be perpendicular to the sliding direction of the movable block 142. Furthermore, for ease of explanation, the following explanation will use the reference direction X to represent the sliding direction of the first display component 121 and the second display component 122, and the first direction Y to represent the sliding direction of the movable block 142.

[0074] Optionally, the structure of the mounting bracket 141 is not limited to a rectangle, and the shape of the mounting bracket 141 can be adapted to meet design requirements. That is, in addition to being arranged in a matrix, the mounting bracket 141 can also be arranged in other regular or irregular shapes, as long as the first display component 121 and the second display component 122 can be slidably connected to the mounting bracket 141. This embodiment does not limit this.

[0075] Optionally, the mounting bracket 141 is perpendicular to the first direction Y and located on one side within the sliding space 1401, and a connecting post 1413 is also provided. That is, one end of the connecting post 1413 can be connected to one long side 1411, and the other opposite end extends towards the other long side 1411, and the extension direction of the connecting post 1413 can pass through the midpoint of the two long sides 1411 respectively. Of course, the extension direction of the connecting post 1413 is not limited to passing through the midpoint of the two long sides 1411. At the same time, the first display component 121 and the second display component 122 can be located on opposite sides of the connecting post 1413 parallel to the first direction Y, and can slide back and forth between the connecting post 1413 and the short side 1412 along the reference direction X. In addition, the connecting post 1413 can also be hinged to the swing rod 144, and the opposite ends of the swing rod 144 can rotate relative to the connecting post 1413. In this embodiment, a connecting shaft 1402 may be provided on the connecting column 1413, and the connecting shaft 1402 may pass through the central area between the two opposite ends of the swing rod 144, so that the two opposite ends of the swing rod 144 can rotate relative to the connecting column 1413 through the connecting shaft 1402.

[0076] Optionally, the adjusting assembly 140 may further include a slide bar 147. For example... Figure 12 As shown, the slide rod 147 can pass through the connecting post 1413 along the reference direction Y, and the opposite ends of the slide rod 147 can be respectively inserted into the opposite sides of the mounting bracket 141 located in the sliding space 1401, that is, respectively inserted into the short sides 1412 at both ends. The first display component 121 and the second display component 122 can both be sleeved on the slide rod 147 and can slide along the reference direction Y on the slide rod 147 to achieve a sliding connection between the mounting bracket 141 and the first display component 121 and the second display component 122. In this embodiment, the slide rod 147 can be cylindrical to improve the smoothness of the sliding of the first display component 121 and the second display component 122 on the slide rod 147. Of course, the cross-section of the slide rod 147 can also be other shapes such as triangle, rectangle, or ellipse, as long as the first display component 121 and the second display component 122 can slide on the slide rod 147.

[0077] Optionally, when the slide bar 147 is cylindrical, to prevent the first display component 121 and the second display component 122 from rotating relative to the slide bar 147, the mounting bracket 141 may also be provided with a limiting groove 1414, and both the first display component 121 and the second display component 122 may be provided with limiting blocks 1201. The limiting groove 1414 may be formed on the long side 1411 that is not connected to the connecting post 1413, and communicate with the sliding space 1401. The limiting block 1201 is disposed within the limiting groove 1414 and can slide within the limiting groove 1414 along the reference direction X. The limiting block 1201 can also engage with the sidewall of the limiting groove 1414 in the second direction Z (perpendicular to both the reference direction X and the first direction Y), so that the engagement of the limiting block 1201 and the sidewall of the limiting groove 1414 restricts the rotation of the first display component 121 and the second display component 122, preventing rotation of the first display component 121 and the second display component 122 relative to the slide rod 147. In this embodiment, there can be two limiting grooves 1414, and the two limiting grooves 1414 can be spaced apart on the long side 1411 not connected to the connecting post 1413, to engage with the limiting blocks 1201 of the first display component 121 and the second display component 122 respectively. Of course, in some embodiments, the two limiting grooves 1414 can also be connected to form a single limiting groove 1414.

[0078] Optionally, the positions of the limiting groove 1414 and the limiting block 1201 can be interchanged. That is, two limiting blocks 1201 can be respectively provided on the long side 1411 that is not connected to the connecting post 1413, and corresponding limiting grooves 1414 can be opened on both the first display component 121 and the second display component 122, and the two limiting blocks 1201 can be respectively provided in the two limiting grooves 1414. With this configuration, the limiting block 1201 and the limiting groove 1414 can still restrict the rotation of the first display component 121 and the second display component 122 by cooperating.

[0079] Optionally, in addition to sliding connection with the mounting bracket 141 via the slide bar 147, the first display component 121 and the second display component 122 can also be slidably connected to the mounting bracket 141 via limiting blocks 1201 and limiting grooves 1414. Taking the first display component 121 as an example, limiting grooves 1414 can be formed on the sides of the two long sides 1411 that are close to each other, and limiting blocks 1201 can be provided on opposite sides of the first display component 121 that are close to the two long sides 1411. The limiting blocks 1201 can still be set in the limiting grooves 1414 and can slide in the limiting grooves 1414 along the reference direction Y to realize the sliding connection between the first display component 121 and the mounting bracket 141. Of course, the positions of the limiting grooves 1414 and the limiting blocks 1201 can still be interchanged, and the specific method is the same as or similar to the aforementioned embodiments, which will not be described in detail here. In addition, considering assembly issues, the mounting bracket 141 can also be designed to be disassembled to facilitate the assembly of the mounting bracket 141 and the display component 120.

[0080] Optionally, since the user's face has a certain curvature, in order to better match the position of the user's eyes with the first display component 121 and the second display component 122, the display surface 1202, that is, the light-emitting surface, can also intersect with the reference direction X. This allows the display surface 1202 of the first display component 121 and the second display component 122 to be tilted relative to the reference direction X, thereby matching the position of the user's left and right eyes on the face, to achieve the effect of expanding the field of view and improving the viewing immersion. Figure 13 As shown, the angle α formed by the intersection of the two display surfaces 1202 and the reference direction X can be the same, and the two display surfaces 1202 can be symmetrically arranged about the first direction Y. Simultaneously, the angle formed by the intersection of the two display surfaces 1202 and the reference direction X can be 5-10°, specifically 5°, 7°, 9°, or 10°. This arrangement not only allows for distance adjustment between the first display component 121 and the second display component 122, but also further improves the matching degree between the first display component 121 and the second display component 122 and the user's left and right eyes by utilizing the tilted display surfaces 1202.

[0081] The movable block 142 is slidably connected to the mounting bracket 141 and is located within the sliding space 1401. For example... Figure 12As shown, the movable block 142 can be positioned opposite and spaced apart from the connecting post 1413 in the first direction Y, and can slide between the connecting post 1413 and the long side 1411 along the first direction Y. For example, the adjustment assembly 140 may also include a push rod 148. One end of the push rod 148 can be connected to the movable block 142, and the other opposite end can pass through the mounting bracket 141 and protrude from the side of the mounting bracket 141 away from the sliding space 1401. That is, the push rod 148 can pass through the long side 1411 that is not connected to the connecting post 1413, and the end of the push rod 148 located in the sliding space 1401 can be connected to the movable block 142, while the other opposite end located outside the sliding space 1401 can be connected to the corresponding drive structure. At the same time, the push rod 148 can be slidably connected to the mounting bracket 141, and can slide along the first direction Y under the drive of the external force applied by the drive structure, so as to push the movable block 142 to slide along the first direction Y in the sliding space 1401. In this embodiment, the driving method of the drive structure can be electric, such as a combination of motor (electric drive) + lead screw / cam, or manual, such as manual + gear / cam / rack, etc.

[0082] Optionally, the push rod 148 can be slidably connected to the mounting bracket 141, or rotatably connected to the mounting bracket 141, and the push rod 148 can rotate relative to the mounting bracket 141 under the drive of the drive structure. Simultaneously, the push rod 148 can also be threaded, and the movable block 142 can also be threaded to match the push rod 148, allowing the movable block 142 to be threadedly connected to the push rod 148. With this configuration, when the push rod 148 rotates under the drive of the drive structure, the movable block 142 can slide relative to the push rod 148 along the first direction Y under the action of the thread, thereby driving the push block 143 to slide in the first direction Y.

[0083] The pushing block 143 is slidably connected to the movable block 142, and the pushing block 143 is also hinged to the swing rod 144, enabling it to push the opposite ends of the swing rod 144 to rotate. Figure 12 and Figure 14As shown, the pushing block 143 may include a sliding part 1431, a first engaging part 1432, and a second engaging part 1433. The sliding part 1431 is slidably connected to the movable block 142 and can slide along the reference direction X. For example, a groove 1421 may be formed on the side of the movable block 142 perpendicular to the reference direction Z, and this groove 1421 may also extend through opposite sides of the movable block 142 in the second direction Z. The sliding part 1431 is disposed within the groove 1421 and can slide within the groove 1421 along the reference direction X. The sliding part 1431 can also engage with the sidewall of the groove 1421 in the first direction Y to limit the displacement of the sliding part 1431 in the first direction Y. Simultaneously, the first mating part 1432 and the second mating part 1433 can be disposed opposite to and spaced apart on opposite sides of the sliding part 1431, and connected to the opposite sides of the sliding part 1431, so as to form a connection space 1434 between the first mating part 1432 and the second mating part 1433 for hinged connection with the swing rod 144. Furthermore, the first mating part 1432 and the second mating part 1433 can also be located on opposite sides of the movable block 142 through which the slide groove 1421 passes, and can engage with the movable block 142 to limit the direction in which the sliding part 1431 approaches or moves away from the second mating part 1433, that is, the displacement in the second direction Z. Through the above arrangement, not only can the sliding connection between the pushing block 143 and the movable block 142 be realized, but the movable block 142 can also limit the displacement of the pushing block 143 in directions other than the reference direction X.

[0084] It is understood that the specific structure of the aforementioned push block 143 is only an illustrative example. In some embodiments, there are multiple ways in which the push block 143 and the movable block 142 can be slidably connected. These will not be described in detail here.

[0085] The swing arm 144 is rotatably connected to the mounting bracket 141, and the two opposite ends of the swing arm 144 can rotate under the push of the push block 143, so as to drive the first connecting rod 145 and the second connecting rod 146 to push the first display component 121 and the second display component 122 to slide. Figure 12As shown, the central regions of the opposite ends of the swing rod 144 can be sleeved on the connecting shaft 1402 of the connecting column 1413, allowing the opposite ends of the swing rod 144 to rotate relative to the connecting column 1413. The opposite ends of the swing rod 144 can also be respectively provided with a first pin 1441 and a second pin 1442. One end of the first connecting rod 145 can be sleeved on the first pin 1441, and one end of the second connecting rod 146 can be sleeved on the second pin 1442, respectively achieving hinged connections between the first connecting rod 145 and the second connecting rod 146 and the swing rod 144. Simultaneously, the pushing block 143 can also be sleeved on the first pin 1441, achieving a hinged connection between the pushing block 143 and the swing rod 144. For example, one end of the swing arm 144 with a first pin 1441 can be located in the connecting space 1434, and the opposite ends of the first pin 1441 can be respectively inserted into the first mating part 1432 and the second mating part 1433, so that the first mating part 1432 and the second mating part 1433 can rotate relative to the swing arm 144 via the first pin 1441. Furthermore, one end of the first connecting rod 145 sleeved on the first pin 1441 can also be located within the connecting space 1434. In this embodiment, the first pin 1441 and the second pin 1442 can be the same as or similar to the connecting shaft 1402.

[0086] With the above configuration, the first connecting rod 145 and the push block 143 can share the first pin 1441 and be hinged to the swing rod 144, thereby simplifying the structural components required for the adjustment assembly 140. Of course, in some embodiments, the push block 143 can also share the second pin 1442 with the second connecting rod 146, or be hinged to the swing rod 144 through a separate pin, as long as the push block 143 can push the opposite ends of the swing rod 144 to rotate. This embodiment does not limit this.

[0087] The first link 145 is hinged to the swing arm 144 and the first display component 121, respectively. The second link 146 is hinged to the swing arm 144 and the second display component 122, respectively. Both the first link 145 and the second link 146 can swing under the action of the swing arm 144, and can respectively push the first display component 121 and the second display component 122 to slide in the reference direction X. Figure 12As shown, one end of the first connecting rod 145 can be sleeved on the first pin 1441, and the other opposite end of the first connecting rod 145 can also be hinged to the first display component 121 through a structure similar to the first pin 1441. One end of the second connecting rod 146 can be sleeved on the second pin 1442, and the other opposite end of the second connecting rod 146 can also be hinged to the second display component 122 through a structure similar to the second pin 1442. With this configuration, when the opposite ends of the swing rod 144 rotate, the first connecting rod 145 and the second connecting rod 146 can swing under the drive of the swing rod 144, and respectively push the first display component 121 and the second display component 122 to slide in opposite directions on the slide rod 147.

[0088] The head-mounted display mechanism 100 provided in this application, by setting a push block 143 slidably connected to the movable block 142, can push the swing rod 144 to rotate when the movable block 142 slides, and slide relative to the movable block 142 under the drive of the swing rod 144. The swing rod 144 can also drive the hinged first link 145 and second link 146 to swing, so that the two display components 120, which are respectively hinged to the first link 145 and the second link 146, can slide under the push of the first link 145 and the second link 146. With this configuration, the movable block 142 can drive the two display components 120 to slide electrically or manually to adjust the relative position of the two display components 120.

[0089] Please see Figures 15 to 17 , Figure 15 yes Figure 1 Another schematic diagram of the connection structure between the two display components 120 and the adjustment component 140. Figure 16 yes Figure 15 A schematic diagram of the connection structure between the two display components 120 and the slider 147. Figure 17 yes Figure 15 A schematic diagram of the connection structure of the moving block 142, the pushing block 143, the first connecting rod 145, and the second connecting rod 146.

[0090] Besides setting the display surfaces 1202 of both the first display component 121 and the second display component 122 to intersect with the reference direction X, thus allowing the display surfaces 1202 of the first display component 121 and the second display component 122 to be tilted relative to the reference direction X to achieve angular sliding of the first display component 121 and the second display component 122, angular sliding of the first display component 121 and the second display component 122 can also be achieved by changing the sliding direction of the first display component 121 and the second display component 122. For example, the sliding direction of the first display component 121 and the sliding direction of the second display component 122 can intersect, and both sliding directions can also intersect with the reference direction X. Figure 16 (As shown), the first display component 121 and the second display component 122 can be tilted relative to the reference direction X, thereby matching the position of the user's left and right eyes on the face, to achieve the effect of expanding the field of view and improving the viewing immersion. With this configuration, the tilting angle of the first display component 121 and the second display component 122 can be achieved by assembling them using conventional first display components 121 and second display components 122, without the need for independent design of the structure of the first display components 121 and the second display component 122 as in the previous embodiment, which helps to reduce the cost required to develop new molds.

[0091] like Figure 15 As shown, in order to adjust the positions of the first display component 121 and the second display component 122 whose sliding directions intersect, the adjustment component 140 in this embodiment may include: a mounting bracket 141, a movable block 142, a pushing block 143, a first connecting rod 145, and a second connecting rod 146. The mounting bracket 141 is disposed within the housing assembly 110 and is slidably connected to the first display component 121 and the second display component 122. The sliding directions of the first display component 121 and the second display component 122 on the mounting bracket 141 intersect, both intersecting at a reference direction X. The movable block 142 is slidably connected to the mounting bracket 141, and the sliding direction of the movable block 142 (i.e., the first direction Y) is perpendicular to the reference direction X. The pushing block 143 is slidably connected to the movable block 142, and the sliding direction of the pushing block 143 is parallel to the second direction Z, and is located between the first display component 121 and the second display component 122. The first link 145 is hinged to the push block 143 and the first display component 121, respectively, and the rotation axis of the first link 145 is perpendicular to the sliding direction of the first display component 121. The second link 146 is hinged to the push block 143 and the second display component 122, respectively, and the rotation axis of the second link 146 is perpendicular to the sliding direction of the second display component 122. For ease of explanation, only the third direction X1 ( Figure 16 (shown) and fourth direction X2 ( Figure 16 (As shown) These refer to the sliding directions of the first display component 121 and the second display component 122, respectively.

[0092] Furthermore, when the movable block 142 drives the push block 143 to slide, the push block 143 can push the first link 145 and the second link 146 to swing, and the first link 145 can simultaneously displace in the second direction Z and the third direction X1, and the second link 146 can simultaneously displace in the second direction Z and the fourth direction X2. Simultaneously, in order not to affect the displacement of the first link 145 and the second link 146 in the second direction Z, the push block 143 can also slide relative to the movable block 142 along the second direction Z along with the first link 145 and the second link 146. In addition, the first link 145 and the second link 146 can also push the first display component 121 and the second display component 122 to slide away from the push block 143, that is, away from each other, thereby increasing the distance between the first display component 121 and the second display component 122, adjusting the first display component 121 and the second display component 122 from the minimum interpupillary distance position to the maximum interpupillary distance position.

[0093] Similarly, when the movable block 142 drives the push block 143 to slide in the opposite direction, the push block 143 can drive the first link 145 and the second link 146 to swing in the opposite direction, and can slide in the opposite direction relative to the movable block 142 under the action of the first link 145 and the second link 146. At the same time, the first link 145 and the second link 146 can respectively drive the first display component 121 and the second display component 122 to slide closer to the push block 143, that is, closer to each other, so as to reduce the distance between the first display component 121 and the second display component 122, thereby adjusting the first display component 121 and the second display component 122 from the maximum interpupillary distance position to the minimum interpupillary distance position. Through the above settings, the movable block 142 can drive the first display component 121 and the second display component 122 to slide at an angle in the direction closer to or farther from each other, so as to adjust the relative position of the first display component 121 and the second display component 122, so that the head-mounted display mechanism 100 can match the interpupillary distance between the left and right eyes of different users, thereby improving the versatility of the head-mounted display mechanism 100.

[0094] For example, unlike the embodiments described above, the adjustment component 140 in this embodiment may include two slide rods 147. Figures 15 to 16As shown, both slide rods 147 are located within the sliding space 1401, and are positioned opposite each other on the connecting post 1413, parallel to the first direction Y. The opposite ends of the two slide rods 147 are respectively inserted into the connecting post 1413 and the mounting bracket 141 (short side 1412). Simultaneously, the extension directions of the two slide rods 147 intersect, and both intersect with the reference direction X, namely the third direction X1 and the fourth direction X2, respectively. The two slide rods 147 can also be symmetrically arranged about the first direction Y. Furthermore, the first display component 121 and the second display component 122 can be respectively fitted onto the two slide rods 147, and can slide along the two slide rods 147 in the third direction X1 and the fourth direction X2, respectively, to achieve a sliding connection between the first display component 121 and the second display component 122 and the mounting bracket 141. In this embodiment, the slider 147 can be cylindrical to improve the smoothness of sliding the first display component 121 and the second display component 122 on the slider 147. Of course, the cross-section of the slider 147 can also be other shapes such as triangle, rectangle or ellipse, as long as the first display component 121 and the second display component 122 can slide on the slider 147.

[0095] Optionally, when the slide bar 147 is cylindrical, to prevent the first display component 121 and the second display component 122 from rotating relative to the two slide bars 147, the mounting bracket 141 may also be provided with a limiting groove 1414, and both the first display component 121 and the second display component 122 are provided with limiting blocks 1201. The specific arrangement and matching method of the limiting groove 1414 and the limiting block 1201 are the same as or similar to those in the aforementioned embodiments, except that the sliding direction of the limiting block 1201 within the limiting groove 1414 is changed from the reference direction X in the aforementioned embodiments to a third direction X1 and a fourth direction X2, to match the sliding directions of the first display component 121 and the second display component 122. This will not be elaborated further here.

[0096] Optionally, similar to the above embodiments, in this embodiment, in addition to the sliding connection between the first display component 121 and the mounting bracket 141 via the slide rod 147, the second display component 122 can also be slidably connected to the mounting bracket 141 via the limiting block 1201 and the limiting groove 1414. Taking the first display component 121 as an example, limiting grooves 1414 can be formed on the side of each of the two long sides 1411 that are close to each other, and limiting blocks 1201 can be provided on the opposite sides of the first display component 121 that are close to the two long sides 1411. The limiting blocks 1201 can still be set in the limiting grooves 1414 and can slide in the limiting grooves 1414 along the reference direction Y to realize the sliding connection between the first display component 121 and the mounting bracket 141. Of course, the positions of the limiting grooves 1414 and the limiting blocks 1201 can still be interchanged, and the specific method is the same as or similar to the above embodiments, which will not be described in detail here. In addition, considering assembly issues, the mounting bracket 141 can also be designed to be disassembled to facilitate the assembly of the mounting bracket 141 and the display component 120.

[0097] like Figure 16 As shown, in this embodiment, the sliding direction of the first display component 121 (third direction X1) and the sliding direction of the second display component 122 (fourth direction X2) both intersect with the reference direction X, and the third direction X1 intersects with the fourth direction X2, thus achieving the angular sliding of the first display component 121 and the second display component 122. Therefore, the display surface 1202 of the first display component 121 can be parallel to the third direction X1, and the display surface 1202 of the second display component 122 can be parallel to the fourth direction X2. Simultaneously, the display surfaces 1202 of the first display component 121 and the second display component 122 can also be symmetrically arranged about the first direction Y to improve the matching degree of the imaging positions of the first display component 121 and the second display component 122. In this embodiment, the included angle α formed by the intersection of the two display surfaces 1202 and the reference direction X can be the same, and the included angle formed by the intersection of the two display surfaces 1202 and the reference direction X can be 5-10°, specifically 5°, 7°, 9°, or 10°. This configuration not only enables the adjustment of the distance between the first display component 121 and the second display component 122, but also allows for further improvement of the matching degree between the first display component 121 and the second display component 122 and the user's left and right eyes by utilizing the tilted display surface 1202.

[0098] The movable block 142 is slidably connected to the mounting bracket 141 and is located within the sliding space 1401. For example... Figure 15As shown, the movable block 142 can be positioned opposite and spaced apart from the connecting post 1413 in the first direction Y, and can slide between the connecting post 1413 and the long side 1411 along the first direction Y. For example, the adjustment assembly 140 may also include a push rod 148. One end of the push rod 148 can be connected to the movable block 142, and the other opposite end can pass through the mounting bracket 141 and protrude from the side of the mounting bracket 141 away from the sliding space 1401. That is, the push rod 148 can pass through the long side 1411 that is not connected to the connecting post 1413, and the end of the push rod 148 located in the sliding space 1401 can be connected to the movable block 142, while the other opposite end located outside the sliding space 1401 can be connected to the corresponding drive structure. At the same time, the push rod 148 can be slidably connected to the mounting bracket 141, and can slide along the first direction Y under the drive of the external force applied by the drive structure, so as to push the movable block 142 to slide along the first direction Y in the sliding space 1401. In this embodiment, the driving method of the drive structure can be electric, such as a combination of motor (electric drive) + lead screw / cam, or manual, such as manual + gear / cam / rack, etc.

[0099] Optionally, the push rod 148 can be slidably connected to the mounting bracket 141, or rotatably connected to the mounting bracket 141, and the push rod 148 can rotate relative to the mounting bracket 141 under the drive of the drive structure. Simultaneously, the push rod 148 can also be threaded, and the movable block 142 can also be threaded to match the push rod 148, allowing the movable block 142 to be threadedly connected to the push rod 148. With this configuration, when the push rod 148 rotates under the drive of the drive structure, the movable block 142 can slide relative to the push rod 148 along the first direction Y under the action of the thread, thereby driving the push block 143 to slide in the first direction Y.

[0100] The pushing block 143 is slidably connected to the movable block 142, and the pushing block 143 is also hinged to the first link 145 and the second link 146 respectively, and can push the first link 145 and the second link 146 to swing. Figure 15 and Figure 17As shown, the pushing block 143 may include a sliding portion 1431 and a hinge portion 1435. The sliding portion 1431 is slidably connected to the movable block 142 and can slide along the second direction Z. For example, a groove 1421 may be formed on the side of the movable block 142 perpendicular to the first direction Y, and this groove 1421 may also extend through opposite sides of the movable block 142 in the second direction Z. The sliding portion 1431 is disposed within the groove 1421 and can slide within the groove 1421 along the second direction Z. The sliding portion 1431 can also engage with the sidewall of the groove 1421 in the first direction Y and the reference direction X to limit the displacement of the sliding portion 1431 in the first direction Y and the reference direction X. Meanwhile, the hinge portion 1435 can be connected to the sliding portion 1431 in the first direction Y, and a first pin 1441 and a second pin 1442 can be respectively provided on opposite ends of the hinge portion 1435, so that the first pin 1441 and the second pin 1442 can be hinged to the first connecting rod 145 and the second connecting rod 146 respectively. In this embodiment, the axial direction of the first pin 1441 can be perpendicular to the sliding direction of the first display component 121 (third direction X1), while the axial direction of the second pin 1442 can be perpendicular to the sliding direction of the second display component 122 (fourth direction X2).

[0101] It is understood that the specific structure of the aforementioned push block 143 is only an illustrative example. In some embodiments, there are multiple ways in which the push block 143 and the movable block 142 can be slidably connected. These will not be described in detail here.

[0102] The first link 145 is hinged to the push block 143 and the first display component 121, respectively, and the second link 146 is hinged to the push block 143 and the second display component 122, respectively. Both the first link 145 and the second link 146 can swing under the influence of the push block 143, and can respectively push the first display component 121 and the second display component 122 to slide. Figure 15 and Figure 17 As shown, one end of the first connecting rod 145 can be sleeved on the first pin 1441, and the other opposite end of the first connecting rod 145 can also be hinged to the first display component 121 through a structure similar to the first pin 1441. One end of the second connecting rod 146 can be sleeved on the second pin 1442, and the other opposite end of the second connecting rod 146 can also be hinged to the second display component 122 through a structure similar to the second pin 1442. With this configuration, when the push block 143 slides along the first direction Y, the first connecting rod 145 and the second connecting rod 146 can swing under the drive of the push block 143, and respectively push the first display component 121 and the second display component 122 to slide.

[0103] The head-mounted display mechanism 100 provided in this application, by setting a push block 143 slidably connected to the movable block 142, can push the first link 145 and the second link 146 hinged to it to rotate when the movable block 142 slides. Under the action of the first link 145 and the second link 146, the movable block 100 can slide relative to the movable block 142, allowing the two display components 120, which are hinged to the first link 145 and the second link 146 respectively, to slide under the push of the first link 145 and the second link 146. With this configuration, the movable block 142 can be electrically or manually driven to slide the two display components 120, thereby adjusting the relative position of the two display components 120.

[0104] 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.
