[0039] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0042] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0044] Based on the existing technology where the vision adjustment device is located inside the head-mounted display module, this application proposes a head-mounted display device that simplifies the structure and facilitates adjustment by allowing the relative movement of the face-fitting module and the head-mounted display module.

[0045] Please refer to Figures 1 to 3 In an optional embodiment of the present invention, the head-mounted display device 100 includes a head-mounted display module 10 and a face-fitting module 30. The head-mounted display module 10 forms a mounting cavity 10a with an opening. The face-fitting module 30 is mounted at the opening of the mounting cavity 10a and partially protrudes from the opening. The face-fitting module 30 is movable in the depth direction of the mounting cavity 10a to adjust the distance between the human eye and the head-mounted display module 10.

[0046] In this embodiment, the head-mounted display module 10 can be AR glasses, VR glasses, or MR glasses, etc., and is not limited thereto. For example, the optical display module is a VR glasses, a virtual reality display device, which includes a housing and an optical engine and an optical structure for transmitting optical engine images to the human eye within the housing, thereby fulfilling visual functions. The head-mounted display module 10 corresponds to the position of the wearer's two eyes, so its shape can be a cuboid or an ellipse, etc. The mounting cavity 10a formed inside facilitates the assembly of the optical structure and optical engine, thereby realizing the display function.

[0047] The face-fitting module 30 is located at the opening of the mounting cavity 10a, meaning it is installed on the side of the head-mounted display module 10 facing the wearer. At least a portion of its structure is made of flexible or elastic material, allowing for easy contact with the face and improved comfort. Furthermore, the flexible and elastic materials can deform appropriately, ensuring a high degree of facial fit and preventing light leakage from the optical engine. When the face-fitting module 30 is applied to the face, the distance between the user's eyes and the optical structure in the head-mounted display module 10 is fixed. By moving the face-fitting module 30 along the depth of the mounting cavity 10a, the distance between the user's eyes and the optical structure can be adjusted, enabling visual acuity adjustment. The specific movement method is not limited; for example, the face-fitting module 30 can be slidably positioned within the mounting cavity 10a using a damped sliding mechanism, allowing for easy sliding of the face-fitting module 30 when visual acuity adjustment is needed. Alternatively, the face-fitting module 30 can be snapped onto the head-mounted display module 10, and the face-fitting module 30 can be provided with multiple snap holes, so that when the snap is located in different snap holes, the face-fitting module 30 can be located at different depths.

[0048] Please refer to Figures 2 to 5 The mounting cavity 10a has at least two stops 1113 formed on the cavity wall near the opening, and the at least two stops 1113 are arranged at intervals along the depth direction of the mounting cavity 10a.

[0049] The head-mounted display device 100 further includes a vision adjustment component 50, which is movably connected to the inner side of the face-fitting module 30. One end of the vision adjustment component 50 passes through the face-fitting module 30. The vision adjustment component 50 has a locking state in which one end engages with one of the at least two settings 1113, and an adjustment state in which one end is disengaged from the settings 1113, so as to adjust the position of the face-fitting module 30 in the depth direction of the head-mounted display module 10.

[0050] To improve the smoothness of adjustment, at least two stops 1113 are provided on the cavity wall of the mounting cavity 10a. These stops 1113 can be groove structures, protruding structures, or other structures formed and installed on the cavity wall of the mounting cavity 10a; no limitation is made here. A vision adjustment component 50 is movably connected to the face-fitting module 30. This movement can be a flexible insertion or a rotatable connection. By driving the vision adjustment component 50 to switch between a locked state and an adjusted state, the fit between the face-fitting module 30 and the head-mounted display module 10 can be relaxed, facilitating the movement of the face-fitting module 30. In other examples, the end of the vision adjustment component 50 can also be inserted into the stop 1113 or other detachable connection methods.

[0051] In the technical solution of the present invention, the head-mounted display module includes a head-mounted display module 10 and a face-fitting module 30 installed on the head-mounted display module 10. The face-fitting module 30 protrudes from the head-mounted display module 10 and is used to fit against the wearer's face, thereby improving comfort and preventing light leakage from the head-mounted display module 10. The cavity wall near the opening of the mounting cavity 10a has at least two positions 1113. The vision adjustment member 50 has a locking state in which one end is engaged with one of the at least two positions 1113, and an adjustment state in which one end is disengaged from the position 1113. In the adjustment state, the face-fitting module 30 moves in the depth direction of the mounting cavity 10a, that is, the distance between the protruding part of the face-fitting module 30 and the lens part inside the head-mounted display module 10 is adjusted, so that when the wearer wears and uses it, the distance between the human eye and the lens part can be adjusted. That is, the head-mounted display device 100 can be adjusted according to the corresponding vision without changing the internal structure of the head-mounted display module 10. The vision adjustment structure of the head-mounted display device 100 of the present invention is simple and easy to adjust, and can adapt to users with different vision needs, thereby improving the user experience.

[0052] Please refer to Figure 4 , Figure 5 and Figure 7 In an optional embodiment, the face-fitting module 30 has a clearance hole 311 on its periphery. The vision adjustment component 50 includes a pressing part 51, a rotating part 53, and a locking part 55. The rotating part 53 and the locking part 55 are spaced apart on one side of the pressing part 51. The rotating part 53 is rotatably connected to the inner side of the face-fitting module 30. The end of the locking part 55 away from the pressing part 51 passes through the clearance hole 311 and extends toward the position 1113. An elastic element 57 is provided between the locking part 55 and the hole wall of the clearance hole 311. In the locked state, the end of the locking part 55 away from the pressing part 51 is locked in a position 1113, and the elastic element 57 is in a natural state.

[0053] In this embodiment, the vision adjustment component 50 is rotatably connected to the inner side of the face-fitting module 30. Specifically, the pressing part 51 is plate-shaped, and the rotating part 53 is connected to one surface of the pressing part 51 and has two shaft ends. The inner sidewall of the face-fitting module 30 has two opposing shaft holes. One shaft end rotates in one shaft hole, so that the pressing part 51 swings at both ends around the shaft end. The engaging part 55 is connected to the surface of the pressing part 51 where the rotating part 53 is located and is close to one end of the pressing part 51. The other end of the engaging part 55 can extend to the position 1113 through the clearance hole 311. When the pressing part 51 is driven away from the end of the engaging part 55, the end of the engaging part 55 can move away from the position 1113, thus being in an adjustment state. At this time, the face-fitting module 30 can be moved to adjust the viewing distance. Correspondingly, the elastic component 57 is in a stretched state. When the pressing part 51 is released, the engaging part 55 is pulled back to the position 1113 under the drive of the elastic member 57 and engages within the position 1113, thus locking the face-fitting module 30 to its position. This structure effectively avoids jamming during use, saving time and effort, and facilitating the movement and adjustment of the face-fitting module 30.

[0054] Optionally, one end of the pressing part 51 may have an anti-slip portion to increase friction and facilitate finger pressing, while also providing a marking for the user to easily operate. The engaging part 55 may be plate-shaped, cylindrical, or other shapes, without limitation, as long as it matches the shape of the corresponding locking position.

[0055] Please combine Figure 6 and Figure 7 In an optional embodiment, the inner side of the face-fitting module 30 is provided with a rotating groove 313, the bottom wall of the rotating groove 313 is provided with the clearance hole 311, the rotating part 53 is rotatably disposed in the middle of the bottom wall of the rotating groove 313, and the bottom wall of the rotating groove 313 is gradually inclined towards the gear position 1113 from the middle to the edge.

[0056] In this embodiment, the rotating groove 313 is provided so that when the pressing part 51 is installed on the face-fitting module 30, it is at least partially embedded in the rotating groove 313, protecting the pressing part 51 and reducing the structure protruding from the inner wall of the face-fitting module 30, resulting in a cleaner appearance and less interference with other structures. A clearance hole 311 is provided at the bottom of the rotating groove 313 to facilitate the passage of the engaging part 55. A clearance space is also formed in the middle of the bottom wall of the rotating groove 313, within which the rotating part 53 is located. Two shaft holes are formed on opposite walls of the clearance space, and these shaft holes also have openings facing the pressing part 51, facilitating the pressing installation of the two shaft ends of the rotating part 53. Furthermore, the bottom of the rotating groove 313 gradually slopes towards the stop 1113 from the center towards the edge, providing more space for the end pressing of the pressing part 51, reducing the height of the rotating part 53, and making the structure of the vision adjustment component 50 more stable and compact.

[0057] Optionally, the bottom of the rotating groove 313 can be an integral structure with the face-fitting module 30, that is, the rotating groove 313 is formed on the inner sidewall of the face-fitting module 30. Alternatively, the bottom of the rotating groove 313 can be a separate structure, with a hole in the inner sidewall of the face-fitting module 30, and the separate structure is installed in the hole, thereby forming the rotating groove 313 by surrounding the hole wall.

[0058] Please refer to Figure 7 and Figure 8 In an optional embodiment, the engaging portion 55 includes two connecting segments 551 arranged at an angle, with the connection point of the two connecting segments 551 facing the rotating portion 53, and the elastic member 57 is connected to the wall of the clearance hole 311 and a connecting segment 551 near the stop 1113.

[0059] In this embodiment, the engaging part 55 is in a bent state, that is, it includes two connecting segments 551 arranged at an angle, and the connecting position of the connecting segments 551 is close to the rotating part 53, that is, the free end of the engaging part 55 is far away from the rotating part 53. In this way, when the pressing part 51 is driven to rotate, only a small distance needs to be pressed to move the free end of the engaging part 55 out of the position 1113, reducing the space occupied by the vision adjustment component 50, thereby saving structure and effort, and improving the convenience of adjustment.

[0060] Please combine Figure 4 and Figure 5 In an optional embodiment, the head-mounted display device 100 further includes a bar gear 11, which is mounted on the cavity wall of the mounting cavity 10a, and a stop 1113 is formed between two adjacent teeth 1111 in the bar gear 11.

[0061] In this embodiment, the structure forming the gear positions 1113 is an independently set structure, namely a bar gear 11. The number of gear positions 1113 can be set according to the number of teeth 1111 in the bar gear 11. The bar gear 11 can be machined separately and then assembled into the head-mounted display module 10. This reduces the machining difficulty of the head-mounted display module 10 housing, facilitates the machining of the gear positions 1113, saves costs, and ensures the machining accuracy of the bar gear 11. Here, the connection method between the bar gear 11 and the head-mounted display module 10 is not limited to bonding or snap-fit ​​connection.

[0062] Please continue to refer to Figure 4 and Figure 5 In an optional embodiment, the bar gear 11 includes two rows of tooth sets 111, which are spaced apart in the circumferential direction of the cavity wall of the mounting cavity 10a. Each tooth set 111 includes a plurality of teeth 1111 spaced apart along the depth direction of the mounting cavity 10a. One end of the vision adjustment member 50 is engaged in two positions 1113 at the same depth of the two tooth sets 111.

[0063] In this embodiment, to further improve stability, the rack gear 11 is configured with two rows of teeth 111. Thus, the two tooth sets 111 can form two positions 1113 at the same depth. During locking, the engaging portion 55 can simultaneously be located within both positions 1113, increasing the connection area with the engaging portion 55 and improving the limiting stability of the vision adjustment member 50. Optionally, the engaging portion 55 includes a connected vertical rod and a horizontal rod. The vertical rod is bent and connected to the elastic member 57, and the horizontal rod is perpendicular to the vertical rod and engages within the two positions 1113. This structure can reduce the size of the clearance hole 311 and form a stable connection structure.

[0064] Please refer to Figure 4 and Figure 5 In an optional embodiment, the bar gear 11 is a ratchet, and each tooth 1111 in the ratchet has a connected arcuate surface 1111a and a stop plane 1111b. In the locked state, one end of the vision adjustment member 50 is engaged with the stop plane 1111b.

[0065] And / or, the cavity wall of the mounting cavity 10a is provided with a fusion column 15, the bar gear 11 is provided with a connecting hole 113, and the fusion column 15 is thermally fused to the wall of the connecting hole 113.

[0066] In this embodiment, a ratchet is selected to cooperate with the vision adjustment component 50. The smooth arc surface 1111a makes it easier for the engaging part 55 to move in one direction, and the stop plane 1111b makes it more difficult for the engaging part 55 to move out of the position 1113 in the opposite direction. This allows the vision adjustment component 50 to slide in one direction during adjustment. Furthermore, the arc surface 1111a bends inward from the opening of the mounting cavity 10a, allowing the user to adjust from the initial end near the opening inwards, avoiding reverse sliding and skipping, thus facilitating the adjustment to a suitable vision value and improving the convenience of adjustment. When different users use the device, they can forcefully drive the pressing part 51 to slide the engaging part 55 to the initial end before adjusting their vision.

[0067] When the shape of the bar gear 11 is limited or not limited, the bar gear 11 is connected to the head-mounted display module 10 by heat fusion. Simply place the bar gear 11 on the cavity wall of the mounting cavity 10a, so that the fusion column 15 passes through the connection hole 113, and then heat the position. This connection method is simple and convenient, and the connection stability is good.

[0068] Please combine Figure 4 and Figure 6 In an optional embodiment, the face-fitting module 30 has a display hole 315 on its periphery, and the head-mounted display module 10 has at least two spaced markers 13 on its inner periphery, with one marker 13 corresponding to one gear position 1113. One end of the vision adjustment component 50 is engaged with one gear position 1113, and the corresponding marker 13 is exposed in the display hole 315.

[0069] And / or, there are two vision adjustment components 50, and at least two positions 1113 are respectively provided on the opposite side walls of the mounting cavity 10a, and one vision adjustment component 50 is correspondingly engaged with one position 1113 of the side wall.

[0070] In this embodiment, a display hole 315 is provided on the periphery of the face-fitting module 30, which can display the corresponding level 1113 indicator 13, thereby visually indicating the adjustment position of the vision adjustment component 50. This allows the user to directly adjust to the corresponding level 1113 during repeated use, avoiding the need for multiple adjustments each time and further improving convenience. The indicator 13 can be truncated cone-shaped, and the display hole 315 is a circular hole, thus fitting the indicator 13 and facilitating its movement. At least two indicators 13 can be numbered or labeled with letters, which is not limited here.

[0071] Based on the limitation or non-limitation of the display hole 315, two vision adjustment components 50 are provided, that is, the opposite ends of the face-mounted module 30 can be adjusted simultaneously, so that the human eye can be directly facing the head-mounted display module 10, improving the viewing experience. Optionally, when the display hole 315 is provided, the adjustment position of the two ends can be seen intuitively, making it easier to adjust the position of the two ends and avoiding inconsistent adjustment of the two ends, further improving the experience.

[0072] Please refer to Figure 6 In an optional embodiment, the face-fitting module 30 includes a face-fitting component 33 and an adjustment bracket 31. The adjustment bracket 31 is movably connected to the cavity wall of the mounting cavity 10a. The face-fitting component 33 is disposed on the side of the adjustment bracket 31 away from the head-mounted display module 10. The vision adjustment component 50 is movably connected to the adjustment bracket 31 and engages with the gear position 1113 to limit the position of the adjustment bracket 31.

[0073] In this embodiment, to improve comfort, the face-fitting component 33 is typically a flexible component, such as foam or silicone. The adjustment bracket 31 is made of a rigid material, facilitating connection and adjustment with the head-mounted display module 10, improving connection stability and smoothness of adjustment. The connection method between the face-fitting component 33 and the adjustment bracket 31 is not limited; it can be adhesive bonding or interference fit. The adjustment bracket 31 is located within the mounting cavity 10a, with the face-fitting component 33 protruding from the opening of the mounting cavity 10a, facilitating a close fit to the wearer's face. The adjustment bracket 31 can move relative to the depth of the mounting cavity 10a. The vision adjustment component 50 is movably connected to the adjustment bracket 31, for example, by rotation or sliding, allowing it to engage in a position 1113, restricting the position of the adjustment bracket 31. By engaging the vision adjustment component 50 in different positions 1113, the adjustment bracket 31 can be positioned at different locations on the head-mounted display module 10.

[0074] Please combine Figure 3 and Figure 6 In an optional embodiment, one of the cavity wall of the mounting cavity 10a and the outer peripheral side of the adjustment bracket 31 is provided with a sliding groove 17, and the other is provided with a limiting buckle 317. The sliding groove 17 extends along the depth direction of the mounting cavity 10a, and the limiting buckle 317 is limited to slide within the sliding groove 17, so that the face-fitting component can be detachably connected to the head-mounted display module 10.

[0075] In this embodiment, to improve the smoothness of adjustment, a limiting buckle 317 is formed on the outer periphery of the adjusting bracket 31, and a sliding groove 17 is formed on the cavity wall of the mounting cavity 10a. The limiting buckle 317 can slide along the extension direction of the sliding groove 17, thereby providing guidance for the movement of the adjusting bracket 31 and improving the ease of movement. To improve the connection stability, the limiting buckle 317 includes a first part and a second part arranged vertically. The cross-section of the second part is larger than that of the first part. The groove space of the sliding groove 17 increases in size from the opening to the bottom of the groove. During assembly, one end of the second part is first inserted into the bottom of the groove from the opening, and then the other end of the second part is inserted into the bottom of the groove, thereby forming a stable connection structure that can slide within the sliding groove 17 without detaching from it, ensuring the assembly stability of the adjusting bracket 31.

[0076] In an optional embodiment, multiple limit buckles 317 are provided, and the multiple limit buckles 317 are arranged at intervals along the circumference of the adjusting bracket 31. Multiple sliding grooves 17 are provided, and one limit buckle 317 is slidably disposed in one sliding groove 17.

[0077] In this embodiment, multiple limiting buckles 317 are provided. The cooperation of multiple limiting buckles 317 and multiple sliding grooves 17 can make the connection between the adjustment bracket 31 and the head-mounted display module 10 more stable, and the movement of the adjustment bracket 31 in the depth direction of the head-mounted display module 10 more stable, avoiding deviation and improving the balance of vision adjustment. Optionally, four limiting buckles 317 are provided, respectively located at the four corners of the adjustment bracket 31, and the positions of the sliding grooves 17 correspond to them, thereby improving the uniformity of the connection structure.

[0078] Please combine Figure 9 and Figure 10 In an optional embodiment, the head-mounted display device 100 further includes an acoustic module 70, which includes two acoustic components 71 and a head-mounted component 73 connecting the two acoustic components 71. Each acoustic component 71 is connected to one end of the head-mounted display module 10 via a connecting arm 75.

[0079] In this embodiment, the acoustic module 70 includes an acoustic component 71 and a headband component 73. The acoustic component 71 is a component with acoustic playback function, which can satisfy acoustic functions and thus enrich the experience of the head-mounted display device 100. There are two acoustic components 71, corresponding to the wearer's two ears respectively. Here, the acoustic component 71 can refer to the two ear-wrap structure in headphones, at least satisfying the audio transmission function, and can also be made of flexible material to make wearing comfortable, which will not be elaborated here. The headband component 73 is a structure connecting the two acoustic components 71. It can be set opposite to the head-mounted display module 10, that is, located at the back of the wearer's head, or located at the top of the wearer's head, which is not limited here. When the head-mounted display module 10 is connected to a wearing structure, the headband component 73 can be connected to the wearing structure to further improve wearing stability. In other examples, the connection between the headband component 73 and the acoustic component 71 is rotatable, so that the wearing position of the headband component 73 can be adjusted. The headband component 73 can be made of either a rigid or flexible material, and there is no limitation on this. In addition, the headband component 73 can also be telescopic in its extension direction, thereby adjusting the distance between the two acoustic components 71 to facilitate wearing by different users and improve applicability.

[0080] The acoustic component 71 is connected to the head-mounted display module 10 via a connecting arm 75. The connecting arm 75 can be a wearing leg of the head-mounted display module 10, a microphone leg of the acoustic component 71, or an independent connecting structure; no limitation is made here. The connection method between the connecting arm 75 and the head-mounted display module 10 can be a fixed connection or a detachable connection; no limitation is made here.

[0081] Please refer to Figures 9 to 11 In an optional embodiment, the connecting arm 75 is magnetically connected to the end of the head-mounted display module 10;

[0082] And / or, the head-mounted module includes a top fixing member 731 and a rear fixing member 733, with the two ends of the top fixing member 731 respectively connected to the two acoustic components 71, and the two ends of the rear fixing member 733 respectively connected to the two acoustic components 71, or, the two ends of the rear fixing member 733 respectively connected to the two ends of the top fixing member 731.

[0083] In this embodiment, the connection between the connecting arm 75 and the head-mounted display module 10 is a magnetic connection, which is detachable. This magnetic connection not only facilitates the assembly and disassembly of the acoustic module 70 but also reduces the risk of breakage due to repeated twisting during use. Furthermore, when the user does not require the display function, the acoustic module 70 can be detached and used independently as a headset, improving its versatility. Optionally, a connecting post is formed at one end of the connecting arm 75, and a connecting groove 10b is formed at the end of the head-mounted display module 10. The connecting post is inserted into the connecting groove 10b, and the connecting post is magnetically connected to the magnetic component within the connecting groove 10b. This structure improves the stability of the magnetic connection and prevents the connecting arm 75 from accidentally detaching. The connecting post can be an electromagnet, generating magnetism when energized and attracting the user, and facilitating detachment when de-energized. Alternatively, the connecting post can be a magnet. In other examples, the connection between the connecting arm 75 and the head-mounted display module 10 can also be a snap-fit ​​connection, etc.

[0084] Based on the connection method between the head-mounted display module 10 and the connecting arm 75, which may or may not be limited, the head-mounted assembly 73 includes a top fixing member 731 and a rear fixing member 733. The top fixing member 731 connects to two acoustic components 71 at both ends and is positioned on the top of the wearer's head during wear. This structure allows it to function as a headphone-like wearing structure for the acoustic components 71 after the connecting arm 75 is detached from the head-mounted display module 10. The rear fixing member 733 is positioned at the back of the wearer's head during wear, providing some weight and fixation for the head-mounted display module 10, thereby further improving the wearing stability of the acoustic components 71 and the head-mounted display module 10. Optionally, the two ends of the rear fixing member 733 can be connected to the two acoustic components 71 or to the two ends of the top fixing member 731; this is not limited. When the acoustic module 70 is not provided, the rear fixing member 733 can also be positioned at both ends of the head-mounted display module 10 for its wearing structure.

[0085] In one example, to further improve the connection stability between the head-mounted display module 10 and the acoustic module 70, a reinforcing member is also connected between the head-mounted assembly 73 and the head-mounted display module 10. This reinforcing member, along with the head-mounted assembly 73, is designed to contact the wearer's head, thereby improving wearing stability. Furthermore, the reinforcing member is detachably connected to the head-mounted display module 10, allowing it to be removed for easy storage when not in use. Optionally, the reinforcing member can be a telescopic component 77, such as a cord and a rotary spring. The rotary spring's rotational deformation allows the cord to be pulled out or retracted, enabling connection or detachment from the head-mounted display module 10.
