Technical Field

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

[0002] With the maturity of VR technology, VR devices are no longer limited to commercial applications; more and more individual users are using VR devices for work, entertainment, or social interaction. Currently, common VR devices generally consist of a headrest and a headset, with the headset able to slide relative to the headrest, making the distance between the two adjustable. However, most VR devices lack a structure to guide the headset, causing it to lose consistency when sliding relative to the headrest and making it prone to stuttering during the movement. Summary of the Invention

[0003] One embodiment of this application provides a head-mounted device, which includes a headrest mechanism and a head-mounted display mechanism. The headrest mechanism includes a housing assembly and a guide assembly disposed on the housing assembly. The head-mounted display mechanism is inserted into the guide assembly and slidably connected to the guide assembly.

[0004] The head-mounted device provided in this application embodiment features a guide component on the housing assembly, with the head-mounted display mechanism inserted into and slidably connected to the guide component. This allows for adjustable distance between the head-mounted display mechanism and the housing assembly, facilitating use by users with different needs. Simultaneously, the guide component provides guidance for the sliding of the head-mounted display mechanism, helping to maintain consistent sliding and reducing the probability of jamming during sliding.

[0022] 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.

[0023] 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.

[0024] This application describes a head-mounted device. This head-mounted device can be an augmented reality (AR) or virtual reality (VR) device, such as AR or VR glasses. Of course, the head-mounted device can also be other devices that need to be worn on the head, such as glasses, or devices with other functions such as lighting that can be worn on the head, which will not be elaborated further. The following detailed description uses AR or VR glasses as an example.

[0025] In examples of augmented reality or virtual reality, the head-mounted device can be configured to transmit and receive data from an external processing device via a signaling connection, which can be wired, wireless, or a combination thereof. However, in other cases, the head-mounted device can be used as a standalone device, i.e., data processing occurs within the head-mounted device itself. The signaling connection can be configured to carry any kind of data, such as image data (e.g., still images and / or fully moving video, including 2D and 3D images), audio, multimedia, voice, and / or any other type of data. The external processing device can be, for example, a game console, personal computer, tablet computer, smartphone, or other type of processing device. The signaling connection can be, for example, a Universal Serial Bus (USB) connection, a Wi-Fi connection, a Bluetooth or Bluetooth Low Energy (BLE) connection, an Ethernet connection, a cable connection, a DSL connection, a cellular connection (e.g., 3G, LTE / 4G, or 5G), or a combination thereof. Additionally, the external processing device can communicate with one or more other external processing devices via a network, which may be, for example, a local area network (LAN), a wide area network (WAN), an intranet, a metropolitan area network (MAN), the Internet, or a combination thereof.

[0026] A head-mounted device may house display components, optics, sensors, and processors. In examples of augmented reality or virtual reality glasses, the display components are designed to function as virtual reality glasses, for example, by projecting light onto the user's eyes, or as augmented reality glasses, by projecting light onto the user's eyes to overlay an image onto the user's view of their real-world environment. The head-mounted device may also include an ambient light sensor and an electronic circuitry system to control at least some of the aforementioned components and perform associated data processing functions. The electronic circuitry system may include, for example, one or more processors and one or more memories.

[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 An exploded view of the head-mounted device 10. Figure 3 yes Figure 2 A schematic diagram of the structure of the head-mounted display mechanism 100. Figure 4 yes Figure 3 A schematic diagram of the connection structure of the central display component 110, the flip component 120 and the support component 130.

[0028] The head-mounted device 10 provided in this application embodiment can be worn on a user's head and can realize virtual reality or augmented reality functions in front of the user's eyes. Figures 1 to 2 As shown, the head-mounted device 10 may include a head-mounted display mechanism 100, a headrest mechanism 200, and an adjustment mechanism 300. The head-mounted display mechanism 100 can be connected to the headrest mechanism 200, and the two together can form a wearing space 101, through which the user wears the head-mounted device 10 on their head. When the user wears the head-mounted device 10, the head-mounted display mechanism 100 can be positioned in front of the user's eyes, enabling virtual reality or augmented reality functions. The headrest mechanism 200 can be positioned behind the user's eyes, providing support for the user's head and housing the functional components required by the head-mounted device 10. The adjustment mechanism 300 can be mounted on the headrest mechanism 200 and connected to the head-mounted display mechanism 100. It can adjust the distance between the head-mounted display mechanism 100 and the headrest mechanism 200 to change the size of the wearing space 101, allowing the head-mounted device 10 to adapt to the user's head size and improving the fit between the head-mounted device 10 and the user.

[0029] The head-mounted display 100 can be worn in front of the user's eyes and can be used to achieve virtual reality or augmented reality functions. For example... Figure 3As shown, the head-mounted display mechanism 100 may include a display component 110, a flip component 120, and a support component 130. When a user wears the head-mounted device 10 on their head, the display component 110 can be positioned in front of the user's eyes, enabling virtual reality or augmented reality functionality. The flip component 120 can connect the display component 110 and the support component 130, allowing the display component 110 to flip relative to the support component 130, enabling the user to flip the display component 110 away from their eyes for better observation of the external environment. The support component 130 can connect the flip component 120 and the headrest mechanism 200, supporting the flip component 120 to flip the display component 110 and also allowing the display component 110 to slide relative to the headrest mechanism 200, changing the distance between them and thus altering the size of the wearing space 101. In this embodiment, the flip component 120, the support component 130, and the headrest mechanism 200 together form the aforementioned wearing space 101.

[0030] Alternatively, the design of the flip component 120 can be omitted, and the display component 110 can be directly fixedly connected to the support component 130. In this case, the wearing space 101 can be formed by the display component 110, the support component 130, and the headrest mechanism 200.

[0031] The display component 110 may include functional components such as an optical engine, display lenses (waveguides), a camera, a speaker, and various sensors, enabling virtual reality or augmented reality functions to be displayed in front of the user's eyes. Figures 3 to 4 As shown, the display component 110 may be provided with a support bracket 111. This support bracket 111 can not only be used to mount the aforementioned functional components, but also to connect with the flip component 120, allowing the display component 110 to flip relative to the support component 130 under the influence of the flip component 120. In addition to the support bracket 111, the display component 110 may also be provided with a housing to accommodate the support bracket 111 and the aforementioned functional components, protecting the functional components mounted on the support bracket 111. In this embodiment, to ensure the connection strength between the support bracket 111 and the flip component 120, the support bracket 111 can be locked to the flip component 120 with screws. Of course, there are other connection methods such as bonding, welding, and snap-fitting, which will not be elaborated upon in this embodiment.

[0032] Optionally, the head-mounted device 10 can also be used to implement functions other than virtual reality or augmented reality, such as camera, lighting, and environmental detection. In this case, the display component 110 can also be replaced by corresponding functional components such as camera components, lighting components, and detection components. That is, using the display component 110 to implement virtual reality or augmented reality functions is only one of the optional embodiments of the head-mounted device 10 provided in this application. In some embodiments, the display component 110 can also be replaced by other functional components to implement functions other than virtual reality or augmented reality.

[0033] Please combine Figure 4 See Figures 5 to 8 , Figure 5 yes Figure 4 Assembly diagram of the central flipping component 120 and the support component 130. Figure 6 yes Figure 5 A magnified view of a portion of point A in the diagram. Figure 7 yes Figure 5 A schematic diagram of the structure of the connecting bracket 121. Figure 8 yes Figure 5 A schematic diagram of the structure of the middle support component 130.

[0034] The flip component 120 can be rotatably connected to the support component 130, and can cause the display component 110 to flip relative to the support component 130. Figures 4 to 6 As shown, the flipping assembly 120 may include a connecting bracket 121 and a limiting member 122. The connecting bracket 121 can connect the carrying bracket 111 and the support assembly 130 respectively, and can rotate relative to the support assembly 130 to cause the carrying bracket 111 to flip relative to the support assembly 130. The limiting member 122 can be disposed on the connecting bracket 121, and the limiting member 122 can engage with the support assembly 130 in the rotation direction of the connecting bracket 121, thereby limiting the rotation of the connecting bracket 121.

[0035] The connecting bracket 121 can be sleeved on the support assembly 130 and can rotate relative to the support assembly 130. The connecting bracket 121 can also be used to enclose and form the aforementioned wearing space 101. Figures 5 to 7As shown, the connecting bracket 121 may have a rotation space 1201, and the support component 130 may be inserted into the rotation space 1201, allowing the connecting bracket 121 to rotate relative to the support component 130. Simultaneously, the rotation space 1201 may also connect to the bearing bracket 111, and it may also be used to lay cables located on the support component 130, so that the cables can be connected to functional components located on the bearing bracket 111, i.e., to the display component 110, via the rotation space 1201. With this configuration, the connecting bracket 121 can not only drive the display component 110 to rotate relative to the support component 130, but it can also be used to lay the cables of the head-mounted device 10 and to shield and protect the cables.

[0036] Furthermore, the connecting bracket 121 may include an upper cover 1211 and a lower cover 1212 connected to each other. The upper cover 1211 and the lower cover 1212 may together enclose the aforementioned rotation space 1201, and the upper cover 1211 and the lower cover 1212 may jointly clamp the support component 130, that is, the support component 130 may be located between the upper cover 1211 and the lower cover 1212 and clamped by the upper cover 1211 and the lower cover 1212. Simultaneously, the upper cover 1211 and the lower cover 1212 may be locked together with screws to improve the connection's firmness. In addition, the supporting bracket 111 may be connected to the side of the lower cover 1212 opposite to the upper cover 1211, and may be locked to the lower cover 1212 with screws to achieve the connection between the display component 110 and the connecting bracket 121. In this embodiment, by setting the connecting bracket 121 into separate parts that jointly clamp the upper cover 1211 and the lower cover 1212 of the support assembly 130, it is beneficial to improve the assembly convenience of the flipping assembly 120 and the support assembly 130.

[0037] Optionally, the upper cover 1211 and the lower cover 1212 may not be connected by screws; they may also be connected by methods such as welding, bonding, or snap-fitting. Optionally, the connecting bracket 121 may not be limited to the disassembled components of the upper cover 1211 and the lower cover 1212 in the aforementioned embodiment. The specific disassembly method can also be adapted to meet design and assembly requirements, as long as the connecting bracket 121 has the aforementioned rotation space 1201. This embodiment does not limit this aspect.

[0038] The limiting member 122 can be disposed within the rotation space 1201, and the limiting member 122 can be locked onto the lower cover 1212 with screws, allowing the limiting member 122 to rotate relative to the support assembly 130 under the drive of the connecting bracket 121. Specifically, when the connecting bracket 121 rotates relative to the support assembly 130, the limiting member 122 can engage with the support assembly 130 in the rotation direction of the connecting bracket 121, thereby restricting the rotation of the connecting bracket 121. This design avoids the problem of excessive twisting of the cable within the rotation space 1201, leading to breakage or failure, due to unrestricted rotation of the connecting bracket 121.

[0039] The support component 130 can be inserted into the connecting bracket 121 and connected to the headrest mechanism 200. It not only drives the display component 110 to slide relative to the headrest mechanism 200, but also supports the connecting bracket 121 to rotate. Figures 6 to 8 As shown, the support assembly 130 may include a support member 131 and a mating member 132. The support member 131 can be connected to the headrest mechanism 200 and can slide relative to the headrest mechanism 200. The support member 131 can also be inserted into the rotation space 1201, meaning that the connecting bracket 121 can be sleeved on the support member 131. The mating member 132 can be disposed on the support member 131 and located within the rotation space 1201. The mating member 132 can engage with the limiting member 122 after the connecting bracket 121 rotates, thereby restricting the rotation of the connecting bracket 121. In this embodiment, the support member 131 can drive the bearing bracket 111 to slide in a direction away from or towards the headrest mechanism 200, thereby expanding or shrinking the wearing space 101.

[0040] The support member 131 may include a first support member 1311 and a second support member 1312, which are separately configured. One end of the first support member 1311 can be inserted into the rotation space 1201 from one side of the connecting bracket 121, and the other end can be connected to the headrest mechanism 200. The first support member 131 can slide relative to the headrest mechanism 200. One end of the second support member 1312 can be inserted into the rotation space 1201 from the opposite side of the connecting bracket 121, and the other end can also be connected to the headrest mechanism 200. The second support member 1312 can also slide relative to the headrest mechanism 200. Furthermore, the first support member 1311 and the second support member 1312 can be symmetrically arranged about the connecting bracket 121 to improve the consistency of their sliding relative to the headrest mechanism 200. With this configuration, the connecting bracket 121 can not only rotate relative to the first support member 1311 and the second support member 1312, but also slide relative to the headrest mechanism 200 under the influence of the first support member 1311 and the second support member 1312.

[0041] With the above configuration, in addition to driving the connecting bracket 121 to slide, the first support member 1311 and the second support member 1312 can also support the connecting bracket 121, allowing the connecting bracket 121 to rotate directly relative to the first support member 1311 and the second support member 1312, thereby driving the load-bearing bracket 111 (i.e., the display component 110) to flip. This allows for the reuse of the first support member 1311 and the second support member 1312 without the need for an additional independent rotating shaft structure to connect to the connecting bracket 121, simplifying the structure of the head-mounted display mechanism 100 and reducing its weight.

[0042] Furthermore, the first support member 1311 and the second support member 1312 can also be made of rigid materials to improve their structural strength. For example, the first support member 1311 and the second support member 1312 can be made of stainless steel. With this configuration, when facing the heavy display component 110, the first support member 1311 and the second support member 1312 can provide rigid support for the connecting bracket 121 carrying the display component 110, and allow the connecting bracket 121 to rotate relative to the first support member 1311 and the second support member 1312, thereby reducing the risk of breakage or failure of the first support member 1311 and the second support member 1312 due to insufficient structural strength.

[0043] Alternatively, in addition to stainless steel, the first support member 1311 and the second support member 1312 may also be made of other rigid materials, as long as they can meet the structural strength requirements of the first support member 1311 and the second support member 1312. This embodiment does not limit this.

[0044] Furthermore, the first support member 1311 and the second support member 1312 can also be used to enclose and form the aforementioned wearing space 101, and both can also have an arc-shaped structure to improve the fit between the enclosed wearing space 101 and the user's head. With this configuration, when the user wears the head-mounted device 10 on their head, the first support member 1311 and the second support member 1312 can also provide rigid support for the user's head to improve the wearing stability of the head-mounted device 10.

[0045] Furthermore, both the first support member 1311 and the second support member 1312 can be provided with a wiring space 1301, and this wiring space 1301 can be used to lay cables connected to the headrest mechanism 200. The following explanation uses only the wiring space 1301 of the first support member 1311 as an example. Figures 6 to 8As shown, the wiring space 1301 can pass through one end of the first support member 1311 inserted into the rotation space 1201 and the other end of the first support member 1311 connected to the headrest mechanism 200, so as to connect the rotation space 1201 and the headrest mechanism 200, so that the cable connected to the headrest mechanism 200 can be connected to the display component 110 through the wiring space 1301 and the rotation space 1201.

[0046] Furthermore, the ends of the first support member 1311 and the second support member 1312 located within the receiving space 1201 can be arranged opposite each other and spaced apart, and the cables in the wiring space 1301 can be led out from between the first support member 1311 and the second support member 1312 into the rotation space 1201. With this arrangement, when the connecting bracket 121 rotates and causes the cables in the rotation space 1201 to move, these cables can move in the area between the first support member 1311 and the second support member 1312 without interfering with the first support member 1311 and the second support member 1312.

[0047] Optionally, the cables within the wiring space 1301 can also be led out to the rotation space 1201 through through holes or slots in other areas of the first support member 1311 and the second support member 1312. Since the cables will move with the rotation of the connecting bracket 121, the dimensions of the through holes or slots on the first support member 1311 can be designed with a certain degree of redundancy to provide clearance for the cables and reduce the probability of interference between the cables and the first support member 1311 during movement.

[0048] Optionally, the support member 131 can also be configured as a first support member 1311 and a second support member 1312 without being separate. That is, the ends of the first support member 1311 and the second support member 1312 located within the rotation space 1201 can also be connected, and the two can be an integral structure, manufactured integrally by processes such as stamping or CNC machining. In this case, the connected first support member 1311 and the second support member 1312 can be directly referred to as support member 131. Correspondingly, the cable located within the wiring space 1301 can also be led out from the area of ​​the support member 131 located within the rotation space 1201 by opening through holes or through slots, as in the aforementioned embodiment.

[0049] The mating component 132 can be disposed on the support component 131 and located within the rotation space 1201. The mating component 132 can engage with the limiting component 122 after the connecting bracket 121 rotates, thereby limiting the rotation of the connecting bracket 121 and preventing excessive twisting of the cable due to unrestricted rotation caused by the connecting bracket 121, which could lead to breakage or failure. Figures 6 to 8As shown, the first support member 1311 and the second support member 1312 are each provided with a mating part 132 at one end of the rotating space 1201. The mating part 132 can be inserted into the wiring space 1301 through the opening that connects the wiring space 1301 and the rotating space 1201. It can be integrally manufactured with the first support member 1311 and the second support member 1312 by in-mold injection molding process.

[0050] Meanwhile, to facilitate cable laying, the cable routing space 1301 can also pass through the mating member 132, allowing the cable to pass through the mating member 132 and be laid within the rotation space 1201. The mating members 132 located on the first support member 1311 and the second support member 1312 can also be arranged opposite each other and spaced apart, allowing the cable to be led out from between the two mating members 132 into the rotation space 1201, thus avoiding interference between the cable and the mating member 132 when the connecting bracket 121 moves.

[0051] Furthermore, the limiting member 122 can be sleeved on the mating member 132, and the limiting member 122 can rotate relative to the mating member 132 under the drive of the connecting bracket 121. After rotation, it can engage with the mating member 132 in the rotation direction of the connecting bracket 121 to limit the rotation stroke of the connecting bracket 121. The limiting member 122 may have a slider 1221, and the mating member 132 may have a groove 1321, with the slider 1221 disposed within the groove 1321. When the connecting bracket 121 drives the limiting member 122 to rotate relative to the mating member 132, the slider 1221 can slide within the groove 1321 and engage with the inner wall of the groove 1321 to limit the rotation of the connecting bracket 121. In this embodiment, since both the first support member 1311 and the second support member 1312 are provided with mating members 132, the number of limiting members 122 can also be two, and the two limiting members 122 can be respectively sleeved on the two mating members 132 to cooperate with the two mating members 132 to achieve snap-fit.

[0052] Specifically, when the display component 110 is positioned in front of the user's eyes, the slider 1221 can engage with one inner wall of the groove 1321. When the user flips the display component 110 to another position, the slider 1221 can slide within the groove 1321 and engage with the other inner wall of the groove 1321, thereby limiting the rotation of the connecting bracket 121. With this configuration, the sliding stroke of the slider 1221 within the groove 1321 corresponds to the rotation stroke of the connecting bracket 121. By limiting the sliding stroke of the slider 1221 within the groove 1321, the rotation stroke of the connecting bracket 121 can be limited, preventing unrestricted rotation of the connecting bracket 121. In this embodiment, when the display component 110 is flipped from in front of the user's eyes to another position, and the slider 1221 engages with the other inner wall of the groove 1321, the user's eyes are not obstructed by the display component 110, allowing the user to observe the external environment. Of course, the specific rotation stroke of the connecting bracket 121 can also be adjusted according to design requirements, and this embodiment does not limit it.

[0053] Optionally, the positions of slider 1221 and groove 1321 can be interchanged. That is, the limiting member 122 can be provided with groove 1321, and the mating member 132 can be provided with slider 1221. Furthermore, besides the limiting member 122 being fitted onto the mating member 132, the mating member 132 can also be fitted onto the limiting member 122, as long as the limiting member 122 and the mating member 132 can rotate relative to each other. Moreover, the limiting member 122 and the mating member 132 are not limited to the fitting method; various fitting methods can be used, as long as they can engage in the rotational direction of the connecting bracket 121. This embodiment does not impose any limitations on this.

[0054] Optionally, the limiting member 122 and the mating member 132 can also be interference-fitted, allowing them to interfere and generate friction when rotating relative to each other, thereby using friction to achieve rotational hovering of the connecting bracket 121. A friction pad can also be provided between the limiting member 122 and the mating member 132 to increase the friction generated by their relative rotation. Optionally, in addition to the interference fit between the limiting member 122 and the mating member 132, the connecting bracket 121 can also be assembled with the first support member 1311 and the second support member 1312 using an interference fit, so that the connecting bracket 121 can also generate friction when rotating relative to the first support member 1311 and the second support member 1312, thereby increasing the friction available for the connecting bracket 121 to achieve rotational hovering.

[0055] Optionally, only one of the first support member 1311 and the second support member 1312 may be provided with a mating member 132, and the number of limiting members 122 may also be one, to match the number of mating members 132. Optionally, when there is only one mating member 132, the mating member 132 can connect the first support member 1311 and the second support member 1312 respectively, and connect the wiring space 1301 of the first support member 1311 and the second support member 1312. In this case, the cable in the wiring space 1301 can be led out by opening a through hole or through groove in the mating member 132, as long as the area where the mating member 132 contacts the limiting member 122 is avoided.

[0056] The head-mounted display mechanism 100 provided in this application embodiment includes a support component 130 connected to and slidable relative to a headrest mechanism 200, and a flip component 120 connected to and rotatable relative to the support component 130. This allows the display component 110 connected to the flip component 120 to not only flip relative to the support component 130 but also slide under the influence of the support component 130. This configuration allows for the reuse of the support component 130, eliminating the need for the pivot structure used to connect the flip component 120 and the support component 130 in some technical solutions, thereby simplifying the structure of the head-mounted display mechanism 100 and reducing its weight.

[0057] See Figures 9 to 12 , Figure 9 yes Figure 2 A schematic diagram of the connection structure between the central support component 130 and the headrest mechanism 200. Figure 10 yes Figure 9 Exploded view of the central headrest mechanism 200. Figure 11 yes Figure 10 A schematic diagram of the connection structure between the middle mounting shell 211 and the guide assembly 220. Figure 12 yes Figure 11 A magnified view of a portion of point B in the middle.

[0058] The headrest mechanism 200 can be connected to the first support member 1311 and the second support member 1312, and can also be used to enclose and form the aforementioned wearing space 101. Figures 9 to 10As shown, the headrest mechanism 200 may include a housing assembly 210 and a guide assembly 220. The housing assembly 210 is positioned opposite and spaced from the display assembly 110, and can be used to mount the adjustment mechanism 300 and the necessary functional components of the head-mounted device 10. The guide assembly 220 can be connected to the housing assembly 210, and can also be connected to the first support member 1311 and the second support member 1312, providing guidance for the sliding of the first support member 1311 and the second support member 1312. In this embodiment, the first support member 1311 and the second support member 1312 can slide relative to the guide assembly 220, causing the display assembly 110 to slide in a direction away from or towards the housing assembly 210, thereby changing the size of the wearing space 101 and improving the fit between the head-mounted device 10 and the user.

[0059] In addition to housing the adjustment mechanism 300, the housing assembly 210 can also be used to house functional components of the head-mounted device 10, such as batteries. Figures 9 to 11 As shown, the housing assembly 210 may include a mounting housing 211 and a fixing bracket 212. The mounting housing 211 may be positioned opposite and spaced apart from the display assembly 110, and may also be connected to the guide assembly 220. It can be used to mount the adjustment mechanism 300 and other functional components required for the head-mounted device 10. The fixing bracket 212 may be disposed within the mounting housing 211, and can be used to fix the guide assembly 220 to the mounting housing 211 to improve the connection strength between the guide assembly 220 and the mounting housing 211.

[0060] The mounting housing 211 can be used to enclose and form the aforementioned wearing space 101, and the mounting housing 211 can be provided with a receiving space 2101. The adjustment mechanism 300 and the functional components (such as batteries) required for the head-mounted device 10 can all be located in the receiving space 2101. At the same time, the guide assembly 220 can also be inserted into the receiving space 2101, so that the cables connected to the functional components in the receiving space 2101 can be laid on the guide assembly 220, and then laid through the guide assembly 220 into the wiring space 1301 of the first support member 1311 and the second support member 1312, so as to realize the electrical connection between the display component 110 and the functional components located in the receiving space 2101.

[0061] like Figures 10 to 11As shown, the mounting housing 211 may include a bottom shell 2111 and a top cover 2112. The bottom shell 2111 may be an open structure, and the top cover 2112 may be placed on top of the bottom shell 2111, forming the aforementioned receiving space 2101 together with the bottom shell 2111. In this embodiment, the bottom shell 2111 and the top cover 2112 may be made of rigid plastic, and they may be assembled using methods such as snap-fit, welding, bonding, and screw connection. Optionally, the mounting housing 211 may not be limited to being disassembled into a bottom shell 2111 and a top cover 2112; it may also be disassembled according to assembly requirements, as long as the mounting housing 211 has the receiving space 2101. This embodiment does not limit this aspect.

[0062] The fixing bracket 212 can be located within the receiving space 2101, and it can also be locked to the base shell 2111 by screws. For example... Figures 10 to 11 As shown, there can be two fixing brackets 212, namely a first fixing bracket 2121 and a second fixing bracket 2122. The first fixing bracket 2121 can be located on one side of the bottom shell 2111, and the second fixing bracket 2122 can be located on the opposite side of the bottom shell 2111. Both the first fixing bracket 2121 and the second fixing bracket 2122 can be connected to the guide assembly 220, and both can be used to fix the guide assembly 220 and the mounting shell 211 to prevent the guide assembly 220 from shaking relative to the mounting shell 211. Optionally, the fixing bracket 212 and the mounting shell 211 can also be an integral structure. That is, when the mounting shell 211 is formed by injection molding, the injection mold can include the structure of the fixing bracket 212, so that the fixing bracket 212 and the mounting shell 211 can be integrally formed by in-mold injection molding.

[0063] It is understood that the aforementioned names "fixed bracket", "first fixed bracket" and "second fixed bracket" can be used interchangeably. That is, in some embodiments, "fixed bracket" can also be referred to as "first fixed bracket" or "second fixed bracket", and "first fixed bracket" can also be referred to as "second fixed bracket".

[0064] Furthermore, the fixed bracket 212 may also be provided with a positioning groove 2123. One end of the guide component 220 inserted into the receiving space 2101 may be located in the positioning groove 2123, so that the side wall of the positioning groove 2123 can be used to restrict the guide component 220 to prevent the guide component 220 from shaking relative to the mounting housing 211. At the same time, in order to facilitate the laying of cables connecting the display component 110 and the battery (the aforementioned functional components located in the receiving space 2101), the bottom wall of the positioning groove 2123 may also be provided with a clearance hole 2124 (e.g., ...) connecting the guide component 220 and the receiving space 2101. Figure 12 As shown), this allows the cables within the accommodating space 2101 to be routed to the guide assembly 220 via the clearance hole 2124.

[0065] To provide support for the user's head and improve wearing comfort, the shell assembly 210 may also include an elastic pad 213. For example... Figure 9 As shown, the elastic pad 213 can be located on the side of the bottom shell 2111 opposite to the top cover 2112. It can be made of flexible materials such as foam, silicone, rubber, and soft plastic. It can provide elastic support for the user's head when the user wears the head-mounted device 10, thereby improving the user's wearing comfort. Optionally, the design of the elastic pad 213 can also be omitted.

[0066] To facilitate the installation of the adjustment mechanism 300, the housing assembly 210 may further include a mounting bracket 214. For example... Figure 10 As shown, the mounting bracket 214 can be disposed within the receiving space 2101, and the mounting bracket 214 can be locked to the bottom shell 2111 by screws. The mounting bracket 214 can be used to separate the functional components and the adjustment mechanism 300 located within the receiving space 2101, and can also be used to mount the adjustment mechanism 300. For example, the space between the mounting bracket 214 and the bottom shell 2111 can be used to mount the functional components required for the head-mounted device 10, while the space between the mounting bracket 214 and the top cover 2112 can be used to mount the adjustment mechanism 300. This arrangement maintains the independence of the adjustment mechanism 300 from the functional components within the receiving space 2101, preventing the adjustment mechanism 300 from interfering with the functional components during movement. Optionally, the design of the mounting bracket 214 can be omitted, and the adjustment mechanism 300 can be directly mounted on the bottom shell 2111 or the top cover 2112.

[0067] The guide component 220 can be connected to the mounting shell 211, and can also connect to the first support member 1311 and the second support member 1312. It can provide guidance for the first support member 1311 and the second support member 1312, enabling them to drive the display component 110 to slide in a direction away from or towards the mounting shell 211. In this embodiment, the guide component 220 can also be used to enclose and form the aforementioned wearing space 101, and can be separately configured from the mounting shell 211. Compared to a scheme where the guide component 220 and the mounting shell 211 are integrally configured, separating the guide component 220 and the mounting shell 211 before assembly allows for separate fabrication of the guide component 220 and the mounting shell 211, simplifying the complexity of the molds required for manufacturing the guide component 220 and the mounting shell 211, thereby reducing the manufacturing difficulty of the guide component 220 and the mounting shell 211.

[0068] like Figures 9 to 11As shown, the guide assembly 220 may include a first guide member 221 and a second guide member 222. One end of the first guide member 221 can be connected to the first support member 1311, and the other end is located on one side of the mounting shell 211 and inserted into the receiving space 2101. The other end of the first guide member 221 may also be located in the positioning groove 2123 of the first fixed bracket 2121. One end of the second guide member 222 can be connected to the second support member 1312, and the other end is located on the opposite side of the bottom shell 2111 and inserted into the receiving space 2101. The other end of the second guide member 222 may also be located in the positioning groove 2123 of the second fixed bracket 2122. Furthermore, the first guide member 221 and the second guide member 222 may be symmetrically arranged about the mounting shell 211 to improve the sliding consistency of the first support member 1311 and the second support member 1312. With this configuration, the first support member 1311 and the second support member 1312 can respectively drive the display component 110 to slide in a direction away from or towards the housing component 210 along the first guide member 221 and the second guide member 222. In this embodiment, the first guide member 221 and the second guide member 222 can both be separately configured from the mounting housing 211 to reduce the difficulty of manufacturing the first guide member 221, the second guide member 222, and the mounting housing 211 in the early stages.

[0069] Furthermore, to prevent the first guide member 221 and the second guide member 222 from detaching from the positioning groove 2123, which is also the receiving space 2101, the housing assembly 210 may also be provided with fixing members 215 for fixing the positions of the first guide member 221 and the second guide member 222. The number of fixing members 215 can be two, to respectively fix the first guide member 221 and the first fixing bracket 2121, and the second guide member 222 and the second fixing bracket 2122. The following explanation only uses the first guide member 221 and the first fixing bracket 2121 as examples. Figure 12 As shown, the fixing member 215 can pass through one end of the first fixing bracket 2121 and the first guide member 221 located in the positioning groove 2123, so that the first guide member 221 can be engaged with the first fixing bracket 2121 in the direction of exiting the positioning groove 2123, that is, in the direction of receiving space 2101, to prevent the first guide member 221 from coming out of the receiving space 2101. In this embodiment, the fixing member 215 can specifically be a pin. Of course, the fixing member 215 can also be other fasteners (such as screws). Optionally, in addition to the fixing member 215, the first guide member 221 can also be fixed in the positioning groove 2123 by means of bonding, welding or snap-fitting.

[0070] Furthermore, the first guide member 221 and the second guide member 222 can also be used to enclose and form the aforementioned wearing space 101, and both can have an arc-shaped structure to improve the fit between the enclosed wearing space 101 and the user's head. Simultaneously, the first guide member 221 and the second guide member 222 can also be rigid, enabling them to guide the first support member 1311 and the second support member 1312. For example, the first guide member 221 and the second guide member 222 can be made of rigid plastic to ensure sufficient structural strength while reducing their weight. Optionally, besides rigid plastic, the first guide member 221 and the second guide member 222 can also be made of other rigid materials, as long as they can guide the sliding of the first support member 1311 and the second support member 1312.

[0071] With the above configuration, the first support member 1311 and the second support member 1312 can slide the display component 110 in a direction away from or near the housing component 210 along the first guide member 221 and the second guide member 222, thereby changing the distance between the display component 110 and the housing component 210, and thus changing the size of the wearing space 101. Compared with a solution without the first guide member 221 and the second guide member 222, the first guide member 221 and the second guide member 222 can improve the sliding consistency of the first support member 1311 and the second support member 1312, and reduce the probability of the first support member 1311 and the second support member 1312 getting stuck. At the same time, the first guide member 221 and the second guide member 222 can also provide rigid support for the user's head, thereby improving the wearing stability of the head-mounted device 10.

[0072] Furthermore, both the first guide member 221 and the second guide member 222 can be provided with a sliding space 2201. This sliding space 2201 not only provides space for the sliding of the first support member 1311 and the second support member 1312, but also allows for the laying of cables extending from the receiving space 2101. The following explanation uses only the sliding space 2201 of the first guide member 221 as an example. Figures 11 to 12As shown, the sliding space 2201 can pass through one end of the first guide member 221 connected to the first support member 1311, and the other end of the first guide member 221 located in the positioning groove 2123, to connect the first support member 1311 and the receiving space 2101. The first support member 1311 can be inserted into the sliding space 2201 and slide within it, and the wiring space 1301 of the first support member 1311 can also be connected to the sliding space 2201. With this configuration, cables located in the receiving space 2101 can be routed through the sliding space 2201 and the wiring space 1301 to achieve electrical connection between the display component 110 and the functional components located in the receiving space 2101.

[0073] Please combine Figure 9 See Figures 13 to 15 , Figure 13 yes Figure 2 A schematic diagram of the connection structure between the central adjustment mechanism 300 and part of the headrest mechanism 200. Figure 14 yes Figure 13 An exploded view of the mounting bracket 214 and the rotating assembly 310. Figure 15 yes Figure 14 A schematic diagram of the connection structure between the turntable 311 and the drive unit 312.

[0074] The adjustment mechanism 300 can be disposed within the accommodating space 2101 and can be connected to the first support member 1311 and the second support member 1312 via the sliding space 2201. It can be used to pull the first support member 1311 and the second support member 1312 to slide relative to the guide assembly 220, thereby changing the distance between the display assembly 110 and the housing assembly 210, and thus adjusting the size of the wearing space 101. Figure 9 and Figure 13 As shown, the adjusting mechanism 300 may include a rotating component 310 and a connecting component 320. The rotating component 310 may be disposed within the receiving space 2101 and located on the mounting bracket 214, and may rotate relative to the mounting bracket 214. The connecting component 320 may be wound around the rotating component 310 and disposed within the sliding space 2201, connected to the first support member 1311 and the second support member 1312. It may pull the rotating component 310 to rotate relative to the mounting bracket 214 under the influence of the first support member 1311 and the second support member 1312. Simultaneously, the rotating component 310 may generate a driving force after being pulled by the connecting component 320, and may rotate in the opposite direction under the action of the driving force, thereby driving the connecting component 320 to pull the first support member 1311 and the second support member 1312.

[0075] Specifically, when the first support member 1311 and the second support member 1312 slide relative to the first guide member 221 and the second guide member 222 in a direction away from the mounting shell 211, the first support member 1311 and the second support member 1312 can drive the connecting assembly 320 to pull the rotating assembly 310 to rotate relative to the mounting bracket 214. The rotating assembly 310 can also generate a driving force after rotation and can rotate in the opposite direction under the action of the driving force, so as to pull the first support member 1311 and the second support member 1312 relative to the first guide member 221 and the second guide member 222 in a direction close to the mounting shell 211 through the connecting assembly 320.

[0076] With this configuration, when a user needs to wear the head-mounted device 10, they can pull the first support member 1311 and the second support member 1312 to slide away from the mounting shell 211, thereby expanding the wearing space 101 to a size larger than the user's head size, making it easier for the user to wear the head-mounted device 10. After the user wears the head-mounted device 10 in the corresponding position, they can release the first support member 1311 and the second support member 1312, allowing the first support member 1311 and the second support member 1312 to slide towards the mounting shell 211 under the drive of the rotating component 310, thereby reducing the wearing space 101 to a size that fits the user's head size. Compared to a fixed wearing space 101 for the head-mounted device 10, the head-mounted device 10 provided in this embodiment allows the user to adapt the size of the wearing space 101 according to their own needs, thereby improving the fit of the head-mounted device 10 to their head.

[0077] like Figures 13 to 15 As shown, the rotating assembly 310 may include a turntable 311 and a driving member 312. The turntable 311 may be mounted on the mounting bracket 214, and a connecting assembly 320 may be arranged around the turntable 311, allowing it to rotate relative to the mounting bracket 214 under the pull of the connecting assembly 320. For example, the turntable 311 may be rotatably connected to the mounting bracket 214 via a rotating shaft mounted on the mounting bracket 214. The driving member 312 may be connected to both the turntable 311 and the mounting bracket 214, and the driving member 312 generates a driving force after the turntable 311 rotates due to the pull of the connecting assembly 320, thereby causing the turntable 311 to rotate in the opposite direction. In this embodiment, when the first support member 1311 and the second support member 1312 slide away from the mounting housing 211, the connecting assembly 320 can cause the turntable 311 to rotate, and the driving member 312 can generate a driving force to cause the first support member 1311 and the second support member 1312 to slide closer to the mounting housing 211.

[0078] Furthermore, the turntable 311 may have a mounting groove 3001 on the side facing the mounting bracket 214, and a receiving groove 3002 may also be formed on the periphery of the turntable 311. The mounting groove 3001 may be annular, used to mount the drive component 312, facilitating its connection to both the mounting bracket 214 and the turntable 311. The receiving groove 3002 may also be annular, used to accommodate the connecting component 320 wound around the first turntable 311 and to limit its movement, reducing the probability of the connecting component 320 detaching from the turntable 311. Optionally, the mounting groove 3001 and the receiving groove 3002 may be omitted.

[0079] To cooperate with the first support member 1311 and the second support member 1312, there can be two turntables 311, namely the first turntable 3111 and the second turntable 3112. Both the first turntable 3111 and the second turntable 3112 can be mounted on the mounting bracket 214 and can rotate relative to the mounting bracket 214. Simultaneously, the first turntable 3111 can be linked to the first support member 1311 via a connecting component 320 wound around it, and the second turntable 3112 can be linked to the second support member 1312 via the connecting component 320 wound around it. With this configuration, when the first support member 1311 and the second support member 1312 slide away from the mounting housing 211, the first turntable 3111 and the second turntable 3112 can rotate relative to the mounting bracket 214 under the pull of the connecting component 320, and the driving member 312 can generate driving force to drive the first turntable 3111 and the second turntable 3112 to rotate in opposite directions.

[0080] It is understood that the aforementioned names "turntable", "first turntable" and "second turntable" can be used interchangeably. That is, in some embodiments, "turntable" can also be called "first turntable" or "second turntable", and "first turntable" can also be called "second turntable".

[0081] The driving component 312 can be connected to the turntable 311. It generates driving force after the turntable 311 rotates due to being pulled by the connecting assembly 320, thereby causing the turntable 311 to rotate in the opposite direction. For example... Figures 14 to 15 As shown, the driving component 312 can be disposed within the mounting groove 3001, with one end of the driving component 312 connected to the bottom wall of the mounting groove 3001 and the other end connected to the mounting bracket 214. The driving component 312 can be a coil spring with elastic deformation capability. When the turntable 311 rotates due to the pull of the connecting assembly 320, since the other end of the driving component 312 is fixed to the mounting bracket 214, the driving component 312 will be subjected to pressure or tension from the turntable 311, resulting in elastic deformation. This allows the driving component 312 to provide elastic force (the aforementioned driving force) to drive the turntable 311 to rotate in the opposite direction.

[0082] Alternatively, in addition to the coil spring, the drive component 312 can also be other structural components with elastic deformation capabilities, as long as the drive component 312 can generate elastic force to drive the turntable 311 to rotate in the opposite direction. Of course, the drive component 312 can also use a motor to generate driving force to drive the turntable 311 to rotate in the opposite direction.

[0083] To cooperate with the first turntable 3111 and the second turntable 3112, the number of driving components 312 can also be two, namely the first driving component 3121 and the second driving component 3122. For example... Figures 14 to 15 As shown, the first driving member 3121 can be disposed in the mounting groove 3001 of the first turntable 3111 and connected to the first turntable 3111 and the mounting bracket 214 respectively. The second driving member 3122 can be disposed in the mounting groove 3001 of the second turntable 3112 and connected to the second turntable 3112 and the mounting bracket 214 respectively. With this configuration, when the first turntable 3111 and the second turntable 3112 are pulled and rotated by the connecting assembly 320, both the first driving member 3121 and the second driving member 3122 can generate elastic force to drive the first turntable 3111 and the second turntable 3112 to rotate in opposite directions respectively.

[0084] It is understood that the aforementioned names "driving component", "first driving component" and "second driving component" can be used interchangeably. That is, in some embodiments, "driving component" can also be referred to as "first driving component" or "second driving component", and "first driving component" can also be referred to as "second driving component".

[0085] Optionally, when the turntable 311 rotates without being pulled by the connecting assembly 320, the drive member 312 can also be in an elastic deformation state to provide elastic force on the turntable 311, so that the turntable 311 has a tendency to pull the connecting assembly 320. With this configuration, the first support member 1311 and the second support member 1312 can maintain a tight fit with the first guide member 221 and the second guide member 222 under the pull of the connecting assembly 320, reducing the probability of the first support member 1311 and the second support member 1312 sliding under the action of external forces (forces other than those applied by the user).

[0086] To enable the first support member 1311 and the second support member 1312 to slide synchronously, the rotating assembly 310 may further include a synchronous pulley 313. For example... Figure 13As shown, the synchronous pulley 313 can also be mounted on the mounting bracket 214 and can rotate relative to the mounting bracket 214. Simultaneously, the synchronous pulley 313 can mesh with the first turntable 3111 and the second turntable 3112 respectively, allowing the first turntable 3111 and the second turntable 3112 to move in tandem, simultaneously pulling the first support member 1311 and the second support member 1312 through the connecting component 320, thereby achieving synchronous sliding of the first support member 1311 and the second support member 1312. In this embodiment, since both the first turntable 3111 and the second turntable 3112 mesh with the synchronous pulley 313, the first turntable 3111 and the second turntable 3112 can rotate in the same direction when pulled by the connecting component 320 or driven by the driving component 312.

[0087] Optionally, the synchronous pulley 313 can be omitted. When the synchronous pulley 313 is omitted, the rotation of the first turntable 3111 and the second turntable 3112 can remain independent, and the directions in which the first turntable 3111 and the second turntable 3112 rotate under the pull of the connecting component 320 or the drive of the drive member 312 can be the same or opposite. In this case, the specific rotation direction of the first turntable 3111 and the second turntable 3112 can be adjusted according to the winding direction of the connecting component 320 and the direction of the elastic force generated by the drive member 312. It is only necessary that the first turntable 3111 and the second turntable 3112 can be linked with the first support member 1311 and the second support member 1312 respectively. This embodiment does not limit this.

[0088] Optionally, since the first turntable 3111 and the second turntable 3112 can be linked together by the synchronous wheel 313, the rotating assembly 310 can also be provided with only one driving member 312, that is, either the first driving member 3121 or the second driving member 3122, so as to drive the first turntable 3111 and the second turntable 3112 to rotate in opposite directions by the first driving member 3121 or the second driving member 3122.

[0089] Optionally, the synchronous pulley 313 can also be equipped with a drive component 312, just like the turntable 311, so that after the synchronous pulley 313 rotates, it can also rotate in the opposite direction through the elastic force generated by the drive component 312, thereby driving the first turntable 3111 and the second turntable 3112 to rotate in the opposite direction, thereby enhancing the elastic force that drives the first turntable 3111 and the second turntable 3112 to rotate in the opposite direction.

[0090] Optionally, when the synchronous pulley 313 is equipped with a drive member 312, at least one of the drive members 312 on the first turntable 3111 and the second turntable 3112, i.e., the first drive member 3121 and the second drive member 3122, can be omitted. In this way, the first turntable 3111 and the second turntable 3112 can rotate in opposite directions solely through the drive member 312 on the synchronous pulley 313, or through either the drive member 312 of the synchronous pulley 313, or any one of the first drive member 3121 and the second drive member 3122.

[0091] The connecting component 320 can be mounted around the turntable 311, and can also be connected to the first support member 1311 and the second support member 1312, and can pull the turntable 311 to rotate under the drive of the first support member 1311 and the second support member 1312. Figure 13 As shown, the connecting assembly 320 may include: a first connector 321 and a second connector 322. One end of the first connector 321 may be wound around the first turntable 3111, and its other end may pass through the clearance hole 2124. Figure 12 (As shown) It is disposed within the sliding space 2201 of the first guide member 221 and connected to the first support member 1311. One end of the second connector 322 may also be wound around the second turntable 3112, and the other end may also be disposed within the sliding space 2201 of the second guide member 222 through the clearance hole 2124 and connected to the second support member 1312.

[0092] Furthermore, since the first guide member 221 and the second guide member 222 are located on opposite sides of the mounting housing 211, the pulling directions of the first connector 321 and the second connector 322 can be opposite. That is, the pulling direction of the first connector 321 pulling the first turntable 3111 to rotate is opposite to the pulling direction of the second connector 322 pulling the second turntable 3112 to rotate. In this embodiment, the first connector 321 and the second connector 322 can specifically be elastic ropes, so that the first connector 321 and the second connector 322 can also have a certain elasticity to reduce the probability of breakage. Optionally, in addition to elastic ropes, the first connector 321 and the second connector 322 can also be other flexible structural components, as long as they can connect the first support member 1311 and the first turntable 3111, and the second support member 1312 and the second turntable 3112. This embodiment does not limit this.

[0093] With this configuration, when the first support member 1311 and the second support member 1312 slide away from the mounting housing 211, the first connector 321 and the second connector 322 can pull the first turntable 3111 and the second turntable 3112 to rotate under the action of the first support member 1311 and the second support member 1312. Similarly, when the first turntable 3111 and the second turntable 3112 rotate in opposite directions under the action of elastic force, the first connector 321 and the second connector 322 can pull the first support member 1311 and the second support member 1312 to slide closer to the mounting housing 211 under the action of the first turntable 3111 and the second turntable 3112.

[0094] Please see Figure 16 , Figure 16 yes Figure 2 A schematic diagram of another connection structure between the central adjustment mechanism 300 and part of the headrest mechanism 200.

[0095] Optionally, the rotating assembly 310 may also consist of only one turntable 311 that is linked to the first support member 1311 and the second support member 1312. For example... Figure 16 As shown, since there is only one turntable 311, both the first connecting member 321 and the second connecting member 322 can be wound around the turntable 311. The pulling directions of the first connecting member 321 and the second connecting member 322 can be opposite, and the first connecting member 321 and the second connecting member 322 can simultaneously pull the turntable 311 to rotate. That is, one end of the first connecting member 321 and the second connecting member 322 can be wound around the turntable 311 in the same direction (clockwise or counterclockwise), and the other ends of the first connecting member 321 and the second connecting member 322 can be led out in opposite directions to the first guide member 221 and the second guide member 222, respectively.

[0096] With this configuration, when the first support member 1311 and the second support member 1312 slide away from the mounting housing 211, the first connector 321 and the second connector 322 can jointly pull the turntable 311 to rotate. Similarly, the turntable 311, under the action of elasticity, can drive the first connector 321 and the second connector 322 to pull the first support member 1311 and the second support member 1312 to slide closer to the mounting housing 211. Compared to a solution with two turntables 311, a single turntable 311 can reduce the number of structural components in the adjustment mechanism 300.

[0097] Optionally, when the first connector 321 and the second connector 322 are simultaneously arranged on the turntable 311, in order to avoid interference between the first connector 321 and the second connector 322, two aforementioned receiving grooves 3002 can be opened on the periphery of the turntable 311 to respectively accommodate the first connector 321 and the second connector 322.

[0098] In this manner, when a user needs to wear the head-mounted device 10, they can pull the first support member 1311 and the second support member 1312 to slide away from the mounting shell 211, thereby causing the first connector 321 and the second connector 322 to pull the first turntable 3111 and the second turntable 3112 to rotate. This expands the wearing space 101 to a size larger than the user's head, making it easier for the user to wear the head-mounted device 10. After the user wears the head-mounted device 10 in the corresponding position, they can release the first support member 1311 and the second support member 1312, allowing the first turntable 3111 and the second turntable 3112 to rotate in opposite directions under the action of elasticity. This causes the first connector 321 and the second connector 322 to pull the first support member 1311 and the second support member 1312 to slide closer to the mounting shell 211, thereby reducing the wearing space 101 to a size that fits the user's head. Compared to a head-mounted device 10 with a fixed wearing space 101, the head-mounted device 10 provided in this application embodiment allows users to adaptively adjust the size of the wearing space 101 according to their own needs, thereby improving the fit of the head-mounted device 10 with themselves after it is worn on the head.

[0099] Because the drive component 312 provides elastic force to drive the turntable 311 to rotate in the opposite direction, when the user puts the head-mounted device 10 on their head, there may be a problem of reduced wearing comfort due to the elastic force constricting the head. Simultaneously, when the first support component 1311 and the second support component 1312 are subjected to an external force capable of overcoming the elastic force generated by the drive component 312, the head-mounted device 10 may also loosen from the user's head. To solve the aforementioned problems, the adjustment mechanism 300 provided in this embodiment may further include a locking component 330, which can lock the user-adjusted wearing space 101 to maintain the size of the user-adjusted wearing space 101 unchanged, thereby solving the aforementioned problems of the head-mounted device 10 constricting the head due to elastic force and easily loosening under external force.

[0100] Correspondingly, the rotating assembly 310 may be provided with a locking wheel 314 that cooperates with the locking assembly 330, and the locking wheel 314 may engage with the turntable 311 to be linked with the first connecting member 321 and the second connecting member 322. Figures 13 to 14As shown, the locking wheel 314 can be mounted on the mounting bracket 214 and can rotate relative to the mounting bracket 214. The locking wheel 314 has a first tooth 3141 and a second tooth 3142 coaxially arranged. The first tooth 3141 is connected to the locking assembly 330 and can engage with the locking assembly 330 in its rotational direction. The second tooth 3142 can mesh with the first turntable 3111, so that the locking wheel 314 can be linked with the first turntable 3111. With this configuration, the locking assembly 330 can restrict the rotation of the first turntable 3111 by limiting the first tooth 3141, thereby locking the sliding of the first support member 1311 and the second support member 1312, so as to maintain the size of the wearing space 101 unchanged.

[0101] Optionally, in addition to meshing with the first turntable 3111, the second tooth 3142 can also mesh with the second turntable 3112 or the synchronous pulley 313. It is only necessary that the second tooth 3142 can be linked with the first turntable 3111 and the second turntable 3112. This embodiment does not limit this.

[0102] The locking component 330 can be disposed on the mounting shell 211, and the locking component 330 can engage with the turntable 311 to lock the sliding of the first support member 1311 and the second support member 1312, thereby achieving the purpose of keeping the size of the wearing space 101 unchanged. Figure 13 As shown, the locking assembly 330 may include a stop member 331 and an elastic member 332. The stop member 331 may be disposed on the bottom shell 2111 and may engage with the first toothed portion 3141. The engagement with the first toothed portion 3141 can be released after sliding relative to the bottom shell 2111. The elastic member 332 may be disposed within the receiving space 2101 and may be connected to both the bottom shell 2111 and the stop member 331. It may undergo elastic deformation after the stop member 331 separates from the first toothed portion 3141, providing elastic force to reset the stop member 331 and engage with the first toothed portion 3141. With this configuration, the stop member 331 can restrict the rotation of the turntable 311 via the first toothed portion 3141, thereby locking the sliding of the first support member 1311 and the second support member 1312 through the turntable 311, thus maintaining the size of the wearing space 101 unchanged.

[0103] The stop member 331 can be inserted into the bottom shell 2111 and can slide relative to the bottom shell 2111 for displacement. The end of the stop member 331 located within the receiving space 2101 has a slot 3311. A first tooth 3141 can be disposed within the slot 3311 and can engage with the inner wall of the slot 3311, allowing the stop member 331 to engage with the first tooth 3141 in the rotational direction. For example, the inner wall of the slot 3311 can be provided with a rack that engages with the first tooth 3141, and the extension direction of the rack can be perpendicular to the sliding direction of the stop member 331. Thus, when the first tooth 3141 starts to rotate, the rack can be driven by the first tooth 3141 to move in its extension direction. Since the sliding direction of the stop 331 is perpendicular to the extension direction, the first tooth 3141 cannot drive the rack, that is, the stop 331 moves, thereby realizing the engagement between the first tooth 3141 and the stop 331.

[0104] Optionally, the design of the slot 3311 can be omitted, and the end of the stop member 331 located in the receiving space 2101 can also be directly provided with a rack that meshes with the first tooth 3141 to cooperate with the first tooth 3141. In addition, the engagement method between the stop member 331 and the first tooth 3141 is not limited to engagement through meshing. The specific engagement method can also be adjusted according to design requirements, and this embodiment does not limit this. Optionally, the stop member 331 is not limited to being provided on the bottom shell 2111. It can also be provided on the top cover 2112, as long as the stop member 331 can mesh with the first tooth 3141 for engagement. This embodiment does not limit this.

[0105] Furthermore, after the stop member 331 slides relative to the bottom shell 2111, the first tooth 3141 can be spaced apart from the inner wall of the slot 3311, that is, separated from the rack. At this time, the rotation of the first tooth 3141 is not restricted by the stop member 331, so as to release the locking state of the first support member 1311 and the second support member 1312, and the user can adjust the size of the wearing space 101 by pulling or releasing the sliding of the first support member 1311 and the second support member 1312. When the wearing space 101 is adjusted to a suitable size, the stop member 331 can be reset under the elastic force generated by the elastic member 332, so that the rack and the first tooth 3141 are engaged again to restrict the rotation of the first tooth 3141 and lock the first support member 1311 and the second support member 1312, thereby keeping the adjusted size of the wearing space 101 unchanged. In this embodiment, the stop member 331 can slide relative to the bottom shell 2111 by being pressed or pulled by the user, and the elastic member 332 can be pressed or stretched by the stop member 331 during the sliding process, thereby generating elastic force through elastic deformation.

[0106] Optionally, the locking wheel 314 can be omitted, and the stop member 331 can directly engage with any one of the first turntable 3111, the second turntable 3112, and the synchronous wheel 313 to restrict the rotation of the first turntable 3111 and the second turntable 3112. Only a rack that cooperates with the first turntable 3111, the second turntable 3112, and the synchronous wheel 313 is required for the stop member 331. Optionally, when the synchronous wheel 313 is omitted, the adjusting mechanism 300 can have two sets of locking components 330 to lock the first turntable 3111 and the second turntable 3112 respectively. The specific locking structure is the same as or similar to the aforementioned embodiments and will not be described in detail here.

[0107] In this way, when a user needs to wear the head-mounted device 10, they can press the stop member 331 to make it slide relative to the bottom shell 2111, thereby releasing the restriction of the stop member 331 on the rotation of the first turntable 3111 and the second turntable 3112. At this time, the user can overcome the elastic force generated by the drive member 312 and pull the first support member 1311 and the second support member 1312 to slide away from the mounting shell 211, thereby expanding the wearing space 101 to be larger than the area under the user's head, thus facilitating the wearing of the head-mounted device 10.

[0108] Furthermore, after the user puts the head-mounted device 10 on their head, they can release the first support member 1311 and the second support member 1312, allowing the first turntable 3111 and the second turntable 3112 to rotate in opposite directions and pull the first support member 1311 and the second support member 1312 towards the mounting shell 211, thereby reducing the wearing space 101. At this time, when the user feels that the wearing space 101 has been reduced sufficiently to match their head size, they can release the stop member 331, allowing the stop member 331 to reset under the elastic force generated by the elastic member 332 and engage with the first turntable 3111, thereby locking the size of the wearing space 101 to remain unchanged. With this setting, the user can adaptively adjust the head-mounted device 10 according to their own needs, improving the fit of the head-mounted device 10 to the user's head when worn.

[0109] The headrest mechanism 200 provided in this embodiment of the application includes a guide component 220 connected to the head-mounted display mechanism 100, which is also inserted into and slidably connected to the guide component 220 on the housing assembly 210. This allows the distance between the head-mounted display mechanism 100 and the housing assembly 210 to be adjustable, facilitating use by users with different needs. Simultaneously, the guide component 220 provides guidance for the sliding of the head-mounted display mechanism 100, helping to maintain the consistency of the sliding and reducing the probability of the head-mounted display mechanism 100 getting stuck during sliding.
