[0059] In related technologies, with the increasing diversification of electronic products, head-mounted displays, as an important medium for human-computer interaction, are gaining popularity. Head-mounted displays, also known as XR glasses, include VR glasses, AR glasses, and MR glasses. They are a new type of head-mounted display device that integrates simulation technology, computer graphics human-computer interface technology, multimedia technology, sensing technology, and network technology. They are high-tech products that utilize computers and the latest sensor technologies to create a novel means of human-computer interaction. When users wear these displays, in addition to seeing stereoscopic images, the images also change as the user's head moves, providing a more immersive experience.

[0060] Head-mounted displays (HMDs) mainly consist of a frame, temples, and hinges connecting the temples and frame. Hinges typically only allow for horizontal movement to accommodate different head sizes. Current display devices often suffer from a limited field of view (FOV). The relatively small and non-adjustable FOV of these devices prevents optimal visualization and makes it difficult to ensure the user's eyes are always in the ideal optical viewing position of the lenses, significantly impacting user experience and display quality.

[0061] To address the problems in the aforementioned related technologies, this application provides a head-mounted display device with a simple structure. The head-mounted display device uses a dual-rotation mechanism to drive the temples to rotate relative to the frame in two directions. This allows the temples to rotate horizontally to accommodate different head sizes of users, and also to rotate vertically to adjust the field of view (FOV), thereby obtaining the best visualization effect and ensuring that the user's eyes are always in the ideal observation position of the lens optics, thus improving the user experience and display effect.

[0062] like Figures 1 to 6 As shown, the head-mounted display device provided in this application includes a frame 11, temples 12, a dual rotation mechanism 13, and an elastic element 14.

[0063] A double-rotation mechanism 13 connects the frame 11 and the temple 12, allowing the temple 12 to rotate relative to the frame 11 around a first axis and a second axis. The first and second axes are perpendicular to each other and form an angle, greater than 0 degrees, enabling the temple 12 to rotate relative to the frame 11 in two directions. The temple 12 is connected to the frame 11 via the double-rotation mechanism 13. The temple 12 can rotate relative to the frame 11 around the first axis or around the second axis. These rotations can be performed independently without affecting each other. In this specification and accompanying drawings, unless otherwise stated, the example is that the first and second axes are perpendicular. The first axis is horizontally arranged from left to right, allowing the temple 12 to rotate relative to the frame 11 in a vertical direction. Figure 2 The Z-direction. The second axis is set vertically, allowing the temple 12 to rotate relative to the frame 11 in the left-right horizontal direction, i.e. Figure 2 The X direction. In other embodiments, the angle between the first axis and the second axis can also be 89 degrees, 80 degrees, 75 degrees, etc.

[0064] An elastic element 14 is disposed between the frame 11 and the temple 12, and is directly or indirectly connected to the frame 11 and the temple 12. A double-rotating mechanism 13 connects to the temple 12; the connection between the double-rotating mechanism 13, the temple 12, and the elastic element 14 can be a fixed connection or an abutment. The elastic element 14 applies a spring force to the temple 12, causing the two temples 12 to tend to move closer to each other along a first axis. The elastic element 14 has a certain elasticity; when the temple 12 swings horizontally relative to the frame 11, the temple 12 will abut against the elastic element 14, thus improving the clamping capacity of the two temples 12 in the horizontal direction. The elastic element 14 is compressible, allowing the temple 12 a certain amount of swing space in the horizontal direction.

[0065] There are two temples 12 and two corresponding double-rotation mechanisms 13. The two temples 12 are spaced apart along the first axis. During the rotation of one temple 12 around the second axis in a direction away from the other temple 12, the elastic element 14 is compressed or pulled by the temple 12, causing deformation. The elastic element 14 applies a spring force to the temple 12 that is indirectly or directly connected to it, so that the temple 12 tends to move closer to the other temple 12 along the first axis. The two elastic elements 14 on the two temples 12 are respectively arranged on the opposite sides of the two temples 12, and the two elastic elements 14 apply a spring force to the two temples 12 respectively, so that the two temples 12 tend to move closer to each other along the first axis.

[0066] When wearing the head-mounted display, the two temples 12 can be rotated around a second axis to adjust the distance between them. The elastic element 14 holds the temples 12 against the user's head, allowing the head-mounted display to be worn comfortably. When field of view (FOV) adjustment is needed, the temples 12 are rotated around a first axis to achieve FOV adjustment, thereby obtaining optimal visualization and ensuring the user's eyes are always in the ideal optical viewing position of the lenses, improving user experience and display quality. After FOV adjustment, the vertical positioning of the temples 12 and the frame 11 can be achieved through a snap-fit ​​mechanism or by the damping force generated by an interference fit.

[0067] It is understood that in the accompanying drawings of this application, the first axis is horizontally arranged and the second axis is vertically arranged, so that the end of the double rotating mechanism 13 near the frame 11 rotates up and down, and the end of the double rotating mechanism 13 near the temple 12 rotates left and right. In other embodiments, the double rotating mechanism 13 can also be configured such that the end of the double rotating mechanism 13 near the frame 11 rotates left and right, and the end of the double rotating mechanism 13 near the temple 12 rotates up and down.

[0068] Optionally, the dual-rotation mechanism 13 includes a first rotating member 131 and a second rotating member 132. The second rotating member 132 is rotatably mounted on the first rotating member 131 about a second axis, or the first rotating member 131 is rotatably mounted on the second rotating member 132 about a first axis.

[0069] When the second rotating member 132 is rotatably mounted on the first rotating member 131 about the second axis, the first rotating member 131 is rotatably mounted on the frame 11 about the first axis and the temple 12 is connected to the second rotating member 132. Alternatively, the first rotating member 131 is rotatably mounted on the temple 12 about the first axis and the frame 11 is connected to the second rotating member 132.

[0070] When the first rotating member 131 is rotatably mounted on the second rotating member 132 around the first axis, the second rotating member 132 is rotatably mounted on the frame 11 around the second axis and the temple 12 is connected to the first rotating member 131. Alternatively, the second rotating member 132 is rotatably mounted on the temple 12 around the second axis and the frame 11 is connected to the first rotating member 131.

[0071] In the accompanying drawings of this specification, the first rotating member 131 is rotatably mounted on the frame 11 about a first axis, the second rotating member 132 is rotatably mounted on the frame 11 about a second axis, and the temple 12 is connected to the second rotating member 132. The temple 12 and the second rotating member 132 can be connected by snap-fit, threaded connection, or other methods. In this way, by hinged sequentially to the frame 11, the first rotating member 131, and the second rotating member 132, the second rotating member 132 drives the temple 12 to rotate relative to the frame 11 in the vertical and horizontal directions.

[0072] Optionally, in one embodiment of this application, the positioning of the temple 12 and the frame 11 in the vertical direction is achieved by a snap-fit ​​mechanism. The double rotation mechanism 13 further includes a positioning snap-fit ​​part 111. The positioning snap-fit ​​part 111 is disposed on the frame 11 or on the second rotating member 132. The first rotating member 131 is provided with a rotating snap-fit ​​part 1312 for engaging with the positioning snap-fit ​​part 111. There are multiple positioning snap-fit ​​parts 111 arranged circumferentially along the first axis and / or multiple rotating snap-fit ​​parts 1312 arranged circumferentially along the first axis.

[0073] Taking the positioning engagement part 111 located on the frame 11 as an example, there are three ways in which the first rotating member 131 and the frame 11 cooperate. The first way is that the frame 11 has multiple positioning engagement parts 111 and the first rotating member 131 has one rotating engagement part 1312, achieving positioning by engaging the rotating engagement part 1312 with one of the positioning engagement parts 111. The second way is that the frame 11 has one positioning engagement part 111 and the first rotating member 131 has multiple rotating engagement parts 1312, achieving positioning by engaging the positioning engagement part 111 with one of the rotating engagement parts 1312. The third way is the same as the first way, where the frame 11 has multiple positioning engagement parts 111 and the first rotating member 131 has multiple rotating engagement parts 1312. By rotating the first rotating member 131, different rotating engagement parts 1312 engage with different positioning engagement parts 111 to achieve positioning when the head-mounted display is adjusted to different field of view angles. The embodiments of this application are described in a third manner, in which the combination of multiple positioning engagement parts 111 and multiple rotating engagement parts 1312 can improve the stability of positioning.

[0074] Furthermore, one end of the first rotating member 131 is fan-shaped and has multiple rotating engagement portions 1312, making the structure of the first rotating member 131 more compact. Both the rotating engagement portion 1312 and the positioning engagement portion 111 include multiple spaced protrusions and grooves formed between two adjacent protrusions. Through the engagement of the protrusions and grooves, the positioning of the first rotating member 131 after swinging adjustment in the vertical direction is achieved.

[0075] In one embodiment, the frame 11 or the second rotating member 132 is provided with a mounting groove 112, and the frame 11 is provided with a positioning plate 113 located in the mounting groove 112, with a positioning engagement part 111 disposed on the positioning plate 113. Since the rotating engagement part 1312 and the positioning engagement part 111 can not only rotate relative to each other, but also engage with each other after rotation, the rotating engagement part 1312 and the positioning engagement part 111 are prone to wear. The positioning engagement part 111 is disposed on the positioning plate 113 and then mounted on the frame 11 or the second rotating member 132, and the rotating engagement part 1312 is disposed on the first rotating member 131, which can improve the replaceability of the head-mounted display device. When the rotating engagement part 1312 and the positioning engagement part 111 are worn, the positioning plate 113 and the first rotating member 131 can be replaced without replacing the frame 11 and the temple 12, avoiding waste and saving costs.

[0076] Optionally, the frame 11 or the second rotating member 132 is provided with a first shaft 114 located within the mounting groove 112. The first axis coincides with the axis of the first shaft 114. The first rotating member 131 is provided with a shaft hole 1314, and the positioning plate 113 is provided with a sleeve hole 115. The positioning plate 113 is sleeved on the first shaft 114 through the sleeve hole 115 and is threadedly connected to the frame 11 or the second rotating member 132 through a threaded fastener C1. Taking the mounting groove 112 and the first shaft 114 both located on the frame 11 as an example, the first shaft 114 is integrally formed with the frame 11, which improves the structural strength.

[0077] The first rotating component 131 is sleeved on the first shaft body 114 through the shaft hole 1314 and rotatably mounted on the first shaft body 114 through the threaded fastener C2. The head of the threaded fastener C2 restricts the first rotating component 131 from detaching from the first shaft body 114. Both the threaded fasteners C1 and C2 are screws, nuts, or similar components. The threaded fastener C1 enables the detachable installation of the positioning plate 113, and the threaded fastener C2 enables the rotatable installation of the first rotating component 131, thus achieving the installation and mating of the positioning plate 113 and the first rotating component 131.

[0078] Optionally, the dual-rotation mechanism 13 further includes a second shaft 133. The second rotating member 132 is rotatably connected to the first rotating member 131 via the second shaft 133. The first rotating member 131 has a first friction surface 1311, and the second rotating member 132 has a second friction surface 1326. The first friction surface 1311 and the second friction surface 1326 abut against each other. Through the mutual abutment of the first friction surface 1311 and the second friction surface 1326, an interference fit is achieved between the first rotating member 131 and the second rotating member 132. When the first rotating member 131 and the second rotating member 132 rotate relative to each other, the frictional force between the first friction surface 1311 and the second friction surface 1326 provides a damping force for the left and right rotation of the temple 12.

[0079] It is understood that in other embodiments, the damping force for the left and right rotation of the temple 12 can also be achieved through the interference fit between the second shaft 133 and the shaft hole 1314.

[0080] like Figures 6 to 9 As shown, in one embodiment, the double rotation mechanism 13 further includes a retaining ring 134. The retaining ring 134 is sleeved on the second shaft 133. The second shaft 133 is a pin, and the retaining ring 134 is disposed at the end of the pin. The retaining ring 134 restricts the axial movement of the pin, thereby preventing the pin from disengaging from the first rotating member 131 and the second rotating member 132, which would cause the first rotating member 131 and the second rotating member 132 to separate.

[0081] Optionally, the elastic element 14 can be an elastic rubber, a spring, a thermoplastic polyurethane elastomer (TPU), a torsion spring, etc. For example, when the elastic element 14 is a torsion spring and is sleeved on the second shaft 133, the two torsion shafts of the torsion spring are respectively connected to the first rotating element 131 and the second rotating element 132.

[0082] Furthermore, the second rotating member 132 has a receiving groove, and the elastic member 14 is disposed in the receiving groove. One side surface of the elastic member 14 abuts against the first rotating member 131, and the other side of the elastic member 14 abuts against the second rotating member 132. The installation of the elastic member 14 in the receiving groove can achieve dust and water protection and ensure the clamping ability of the temple in the horizontal direction.

[0083] In one embodiment, the first rotating member 131 has a limiting portion 1313, and the second rotating member 132 has an abutting portion 1323. The limiting portion 1313 is located on the rotation path of the abutting portion 1323. Specifically, one end of the second rotating member 132 is provided with the abutting portion 1323 and is fitted onto the first rotating member 131. The limiting portion 1313 is located on the rotation path of the abutting portion 1323. When the second rotating member 132 rotates clockwise and counterclockwise relative to the first rotating member 131 to a certain angle, the abutting portion 1323 will abut against the limiting portion 1313, thereby limiting the rotation angle between the second rotating member 132 and the temple 12. Alternatively, the limiting portion 1313 may only limit the rotation range of the temple 12 in one direction. For example, the limiting portion 1313 may only limit the range when the two temples 12 rotate in mutually distancing directions. By setting the limiting part 1313 and the abutting part 1323 in cooperation, the second rotating member 132 can rotate within a certain range, which can adapt to users with different head circumferences. This avoids the second rotating member 132 causing the temple 12 to rotate at an angle that greatly exceeds the user's head circumference, thus preventing adjustment difficulties. It also ensures that both the first rotating member 131 and the second rotating member 132 maintain contact with the elastic member 14. Optionally, the double rotation mechanism 13 also includes a limiting member 135, which is disposed at the opening of the receiving groove. The limiting member 135 and the inner wall of the receiving groove together form a slot 136, in which the elastic member 14 is engaged, thus realizing the installation of the elastic member 14.

[0084] Furthermore, the elastic element 14 is made of thermoplastic polyurethane elastomer (TPU). Compared to springs, torsion springs, and other elastic elements, TPU has the characteristics of high tensile strength, high tensile force, and high wear resistance, and can withstand greater loads and impacts. One end of the thermoplastic polyurethane elastomer abuts against the first rotating element 131, and the other end of the thermoplastic polyurethane elastomer is engaged in the slot 136 and applies elastic force to the second rotating element 132. When the temple 12 swings left and right under the drive of the second rotating element 132, it will press against the thermoplastic polyurethane elastomer. The thermoplastic polyurethane elastomer has a certain elasticity, which improves the clamping ability of the temple 12 in the horizontal direction. At the same time, the thermoplastic polyurethane elastomer is compressible, which allows the temple 12 to have a certain swing space in the horizontal direction.

[0085] Optionally, the second rotating member 132 includes a housing 1321 and a cover plate 1322. The cover plate 1322 is engaged with the housing 1321 and together they enclose a receiving groove. The cover plate 1322 is engaged with the hook groove of the housing 1321 by a barb. A wearing space 15 is formed between the two temples 12. The cover plate 1322, the limiting member 135, the elastic member 14, and the housing 1321 are arranged sequentially in a direction away from the wearing space 15. The cover plate 1322 is closer to the wearing space 15, and the housing 1321 is farther away from the wearing space 15. The elastic member 14 is close to the inner side of the second rotating member 132 to facilitate wiring within the receiving groove of the second rotating member 132. When the head-mounted display is worn, the user's head is located within the wearing space 15.

[0086] In one embodiment, the limiting member 135 is made of metal, one end of the temple 12 is snapped into the housing 1321, at least a portion of the limiting member 135 is connected to the temple 12, and at least a portion of the limiting member 135 is installed in the housing 1321 by threaded fasteners C3, thereby improving the installation strength of the limiting member 135. The threaded fasteners C3 are fasteners such as screws and nuts. The limiting member 135 can be fixed to the temple 12 and located on the outer side of the temple 12, that is, the thermoplastic polyurethane elastomer is located on the outer side of the first rotating member 131 and the second rotating member 132, saving space in the second rotating member 132 and the temple 12, and facilitating wiring.

[0087] Furthermore, the frame 11 has a first wiring channel, the first rotating member 131 has a second wiring channel 1315, the limiting member 135 and the cover plate 1322 form a third wiring channel 1325, and the temple 12 has a fourth wiring channel. The first wiring channel, the mounting groove 112, the second wiring channel 1315, the third wiring channel 1325, and the fourth wiring channel are connected to form a wiring space, which is used to accommodate the wiring structure of the head-mounted display device. The wiring is laid through the first wiring channel, the mounting groove 112, the second wiring channel 1315, the third wiring channel 1325, and the fourth wiring channel, avoiding the exposure of cables.

[0088] Compared to the connection method where the elastic element 14 is located in the middle of the second wiring channel 1315 and the receiving groove and connects the first rotating element 131 and the second rotating element 132, the elastic element 14 of this application uses thermoplastic polyurethane elastomer and is attached to the inner wall of the second wiring channel 1315 and the receiving groove. This results in a larger space at the second shaft 133, making it easier to lay out the flexible circuit board (FPC) and other circuits of the head-mounted display device. When the temple 12 is folded, the flexible circuit board will not be damaged due to hard bending, increasing the bending life of the flexible circuit board.

[0089] In one embodiment, the head-mounted display device further includes a button assembly 16, a flexible printed circuit board (FPC), and a camera and a control module, both disposed on the frame 11. The flexible printed circuit board passes through a first wiring channel, a mounting slot 112, a second wiring channel 1315, a third wiring channel 1325, and a fourth wiring channel. The button assembly 16 is disposed on the temple 12. The camera and the control module are electrically connected, and the control module is electrically connected to the button assembly 16 via the flexible printed circuit board. This application reduces the area occupied by the vertical and horizontal swing structure by integrating a dual rotation mechanism 13, increasing the space that can be accommodated within the frame 11, thereby facilitating the integration of multifunctional modules such as cameras and control modules within the frame 11.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
