Description

Technical Field

[0001] This invention relates to a display device, and more particularly to a head-mounted display device and wearable components. Background Technology

[0002] With the rapid development of the technology industry, display devices are becoming increasingly diverse in form, function, and usage, leading to the emergence of head-mounted display devices that can be directly worn on the user's body. There are many types of head-mounted display devices. Taking eye mask-type head-mounted display devices as an example, after wearing such devices, users can not only see stereoscopic images, but the images will also change as the user's head moves, providing a more immersive experience.

[0003] The front assembly of a head-mounted display device is worn onto the user's face via a wearable component, allowing the display module of the front assembly to project an image towards the user's eyes. Since each user's head size is different, the wearable component needs to be adjusted when wearing the head-mounted display device. Therefore, how to quickly and easily adjust the wearable component is an important area of ​​current development. Summary of the Invention

[0004] The present invention provides a head-mounted display device that allows for quick and convenient adjustment of its wear size.

[0005] This invention provides a wearable component that allows for quick and convenient adjustment of the wear size of a head-mounted display device.

[0006] The head-mounted display device of the present invention includes a front-end assembly and a wearable assembly. The wearable assembly is connected to the front-end assembly and is adapted to be worn on a user's face. The wearable assembly includes a bracket, a coupling mechanism, a plurality of side headbands, a button, and a reset member. The coupling mechanism is disposed within the bracket. The side headbands are individually connected to the front-end assembly and pass through the bracket. The button is movably connected to the bracket and coupled to the coupling mechanism. The reset member is disposed between the bracket and the coupling mechanism. When the button is pressed relative to the bracket, the button causes the coupling mechanism to decouple the side headbands, allowing the side headbands to move freely relative to the bracket to adjust the distance between the bracket and the front-end assembly. When the button is released relative to the bracket, the reset member causes the coupling mechanism to couple the side headbands, and the coupling mechanism tightens the side headbands relative to the bracket.

The wearable assembly includes a bracket, a coupling mechanism, a plurality of side headbands, a button, and a reset member. The coupling mechanism is disposed within the bracket. The side headbands are individually connected to the front-end assembly and pass through the bracket. The button is movably connected to the bracket and coupled to the coupling mechanism. The reset member is disposed between the bracket and the coupling mechanism. When the button is pressed relative to the bracket, the button causes the coupling mechanism to decouple the side headbands, allowing the side headbands to move freely relative to the bracket to adjust the distance between the bracket and the front-end assembly. When the button is released relative to the bracket, the reset member causes the coupling mechanism to couple the side headbands, and the coupling mechanism tightens the side headbands relative to the bracket.

[0008] Based on the above, in this invention, the head-mounted display device uses a button to activate a coupling mechanism, giving the side headbands freedom of movement relative to the bracket, thereby adjusting the distance between the bracket and the front-end component. This allows the user to quickly and conveniently adjust the size of the head-mounted display device. Furthermore, when the button is released, a reset member can tighten the side headbands via the coupling mechanism, continuously and subtly reducing the distance between the bracket and the front-end component, allowing the head-mounted display device to remain more closely fitted to the user's head.

[0047] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0048] Please refer to Figure 1A and Figure 1B In this embodiment, the head-mounted display device 10 includes a front-end assembly 11 and a wearable assembly 100. The wearable assembly 100 includes a bracket 110, a coupling mechanism 120, a plurality of side headbands 130, a button 140, and a reset member 150. The coupling mechanism 120 is disposed within the bracket 110. The wearable assembly 100 is connected to the front-end assembly 11 via the side headbands 130, and the side headbands 130 pass through the bracket 110. The button 140 is movably connected to the bracket 110 and coupled to the coupling mechanism 120. The reset member 150 is disposed between the bracket 110 and the coupling mechanism 120. When the button 140 is pressed relative to the bracket 110, the button 140 causes the coupling mechanism 120 to decouple the side headbands 130, allowing the side headbands 130 to move freely relative to the bracket 110 to adjust the distance between the bracket 110 and the front-end assembly 11. When the button 140 is released relative to the bracket 110, the reset member 150 drives the coupling mechanism 120 to couple the side headbands 130, and tightens the side headbands 130 relative to the bracket 110 via the coupling mechanism 120.

[0049] In this embodiment, the front-end component 11 may include an optical system (not shown) and a protective housing, and may be equipped with or adapted to house a display. The aforementioned display may be a built-in display or an external portable display (e.g., a smartphone), but the invention is not limited thereto. The type of display may vary depending on whether the head-mounted display device 10 is used in a virtual reality system, an augmented reality system, or a mixed reality system. The optical system includes optical elements for changing the light path of the display, such as lenses, light guides, or prisms.

[0050] On the other hand, in this embodiment, the headband display device 10 may also include an auxiliary headband 12. The auxiliary headband 12 connects the front-end component 11 and the wearable component 100, and the side headbands 130 and the auxiliary headband 12 are adapted to wear the front-end component 11 onto the user's head.

[0051] Please refer to Figure 2A and Figure 2B The coupling mechanism 120 may include a first rotating member 121, a second rotating member 122, and a movable member 123. The first rotating member 121 is rotatably connected to the bracket 110 and coupled to the movable member 123 and the button 140. The second rotating member 122 is rotatably connected to the bracket 110 and coupled to the movable member 123 and the side straps 130. The movable member 123 is movably connected to the bracket 110. Specifically, when the button 140 is pressed relative to the bracket 110 to rotate the first rotating member 121, the first rotating member 121 causes the movable member 123 to move and disengage from the second rotating member 122, allowing the side straps 130 to move freely relative to the bracket 110 to adjust the length of each side strap 130 protruding from the bracket 110.

[0052] In this embodiment, the bracket 110 may include a front cover 111, a rear cover 112, and a frame 113. The frame 113 is disposed between the front cover 111 and the rear cover 112, and the rear cover 112 may have an opening 112a. A button 140 is movably disposed within the bracket 110 and protrudes from the opening 112a. The button 140 may include a pressing portion 141 and a coupling portion 142. The pressing portion 141 extends beyond the opening 112a. The coupling portion 142 extends from the pressing portion 141 into the bracket 110 and couples to a first rotating member 121. The first rotating member 121 passes through the frame 113 and is pivotally connected to the front cover 111, allowing the first rotating member 121 to rotate relative to the frame 113. A second rotating member 122 is disposed between the rear cover 112 and the frame 113 and is pivotally connected to the rear cover 112, allowing the second rotating member 122 to rotate relative to the frame 113. The second rotating member 122 is also coupled to these side head straps 130. When the second rotating member 122 rotates relative to the frame 113, it will cause these side head straps 130 to move relative to the bracket 110, thereby changing the length of each side head strap 130 exposed from the bracket 110.

[0053] In this embodiment, the first rotating member 121 and the second rotating member 122 are gears, and the moving member 123 may include a moving rack portion 123a. The first rotating member 121 and the second rotating member 122 each mesh with the moving rack portion 123a. The coupling portion 142 of the button 140 may have a button rack portion 142a, and the button rack portion 142a meshes with the first rotating member 121. The moving member 123 may also have a moving hook portion 123b, which is disposed on the side near the second rotating member 122. The frame 113 of the bracket 110 may also have a bracket hook portion 113a and a bracket slot 113b. The moving member 123 is disposed on one side of the bracket slot 113b. The moving hook portion 123b protrudes from the bracket slot 113b and can move within the bracket slot 113b. The two ends of the reset member 150 are hooked by the movable hook portion 123b and the bracket hook portion 113a, respectively, and the reset member 150 provides a restoring force to the movable member 123, causing the movable hook portion 123b to move in the direction of the bracket hook portion 113a. In this embodiment, the reset member 150 may be an elastic spring ring or a magnetic magnet assembly to provide a restoring force to the movable member 123, causing the movable member 123 to move in the direction of the bracket hook portion 113a, but is not limited thereto.

[0054] In this embodiment, the bracket slot 113b may have a first end E1 and a second end E2. The first end E1 is close to the second rotating member 122 and the bracket hook 113a, while the second end E2 is close to the first rotating member 121. When the reset member 150 connects the movable hook 123b and the bracket hook 113a, the reset member 150 applies a restoring force to the movable member 123, causing the movable member 123 to abut against the position of the first end E1. When the movable member 123 is subjected to an external force that is opposite in direction to the restoring force and greater than the restoring force, the movable member 123 will move towards the position of the second end E2.

[0055] In this embodiment, each of the side headbands 130 may have a headband slot 131 and a headband rack portion 132. The second rotating member 122 passes through these headband slots 131 and engages with these headband rack portions 132. When the side headbands 130 move closer to each other, the length of the side headbands 130 protruding from the bracket 110 becomes shorter, thus shortening the distance between the front end assembly 11 and the bracket 110. When the side headbands 130 move away from each other, the length of the side headbands 130 protruding from the bracket 110 becomes longer, thus lengthening the distance between the front end assembly 11 and the bracket 110.

[0056] Please refer to Figure 3A and Figure 4AWhen button 140 is not pressed, reset member 150 applies a restoring force to moving member 123, causing moving hook 123b to abut against first end E1. In this state, moving member 123 is fixed and cannot move relative to bracket 110, so that first rotating member 121 and second rotating member 122, which are simultaneously engaged with moving member 123, cannot rotate relative to bracket 110. When second rotating member 122 is fixed, the side straps 130, which are simultaneously engaged with second rotating member 122, also cannot move relative to bracket 110.

[0057] Please refer to Figure 3B , Figure 3C , Figure 4B and Figure 4C When the user presses the pressing part 141 of the button 140, the pressing part 141 is subjected to an external force F and moves relative to the bracket 110, causing the coupling part 142 to move towards the first rotating member 121 along with the movement of the pressing part 141, and driving the first rotating member 121 to rotate. When the pressing part 141 abuts against the frame 113 of the bracket 110 and stops moving, the coupling part 142 also stops moving along with the pressing part 141, and the first rotating member 121 stops rotating.

[0058] On the other hand, when the first rotating member 121 is rotated, it will drive the moving member 123 to move away from the second rotating member 122. Specifically, when the pushing force exerted on the moving member 123 by the first rotating member 121 is greater than the restoring force exerted on the moving member 123 by the reset member 150, the first rotating member 121 will drive the moving member 123 to move relative to the bracket 110. At this time, the moving hook 123b moves from the first end E1 to the second end E2 along with the moving member 123 in the bracket slot 113b. When the moving hook 123b moves to the second end E2, the moving member 123 will disengage from the second rotating member 122. At this time, the second rotating member 122 is not engaged with the moving member 123, allowing the second rotating member 122 to rotate freely relative to the bracket 110.

[0059] As described above, when the second rotating member 122 can rotate freely relative to the bracket 110, the side straps 130 have the freedom to move relative to the bracket 110. At this time, the user can adjust the distance between the front end assembly 11 and the bracket 110 by adjusting the length of each side strap 130 protruding from the bracket 110. It is worth noting that in this state, because the pressing part 141 is continuously subjected to an external force F, preventing the coupling part 142 from moving, the first rotating member 121, which meshes with the button rack part 142a, cannot rotate relative to the bracket 110. This fixes the moving member 123, which meshes with the first rotating member 121, preventing it from moving towards the bracket hook part 113a.

[0060] Please refer to Figure 3D , Figure 3E , Figure 4D and Figure 4E When the user releases button 140, the external force F applied to the pressing part 141 is released, allowing the first rotating member 121 to rotate freely relative to the bracket 110. At this time, the moving member 123 is only subjected to the restoring force applied by the reset member 150, causing the moving hook part 123b to move from the second end E2 to the first end E1 and abut against the first end E1.

[0061] As described above, during the movement of the movable member 123 from the second end E2 to the first end E1, the movable member 123 engages with the second rotating member 122 again. At this time, the movable member 123 is driven by the restoring force of the reset member 150 to rotate the second rotating member 122 relative to the bracket 110. When the second rotating member 122 rotates, the headband rack portions 132 engaged with the second rotating member 122 move closer to each other as the second rotating member 122 rotates, and drive the side headbands 130 to move in each other's direction, thereby slightly shortening the distance between the front end assembly 11 and the bracket 110, so that the headband display device 10 can be more continuously close to the user's head.

[0062] On the other hand, as the moving member 123 moves from the second end E2 towards the first end E1, the moving member 123 drives the first rotating member 121, causing the first rotating member 121 to drive the coupling part 142 to move toward the opening 112a of the bracket 110. At this time, the pressing part 141 moves with the coupling part 142 and returns to its initial position.

[0063] Specifically, the reset member 150 provides a restoring force to the movable member 123, causing the movable member 123 to move towards the first end E1. When no external force is applied to the wearable assembly 100, the restoring force applied to the movable member 123 by the reset member 150 causes the movable member 123 to abut against the first end E1. At this time, the first rotating member 121 and the second rotating member 122, which are engaged with the movable member 123, cannot rotate relative to the bracket 110, thereby preventing the side headbands 130 from moving relative to each other. When an external force F is applied to move the movable member 123 towards the second end E2, the movable member 123 disengages from the second rotating member 122, allowing the second rotating member 122 to rotate freely relative to the bracket 110, thereby giving the side headbands 130 a degree of freedom to move relative to the bracket 110.

[0064] When the external force F is released, the restoring force of the reset member 150 causes the moving member 123 to move towards the bracket hook 113a. The moving member 123 re-engages with the second rotating member 122, causing the second rotating member 122 to rotate, thereby driving the side headbands 130 to move towards each other, further reducing the distance between the front end assembly 11 and the bracket 110. In other words, after pressing the button 140, the user can adjust the length of each of the side headbands 130 exposed from the bracket 110, adjusting the head-mounted display device 10 to fit the user's head size. After the user has adjusted the side headbands 130 and released the button 140, the restoring force of the reset member 150 can be used to tighten the side headbands 130 via the coupling mechanism 120, continuously and slightly reducing the distance between the front end assembly 11 and the bracket 110, so that the head-mounted display device 10 is closer to the user's head.

[0065] Please refer to Figure 5 Another embodiment illustrated therein is similar to Figure 1A The embodiments are largely the same. The differences between the two are as follows. Figure 1A In this embodiment, the side headbands 130 are directly connected to the front-end component 11. In this embodiment, the head-mounted display device 10 may also include a front headband 13. The front headband 13 connects the wearable component 100 to the front-end component 11, and the front headband 13 is pivotally connected to the front-end component 11. Specifically, the front headband 13 may connect to the side headbands 130. The front headband 13 may be integrally formed with the side headbands 130. When the side headbands 130 move relative to the bracket 110, the distance between the bracket 110 and the front headband 13 can be adjusted, thereby adjusting the distance between the bracket 110 and the front-end component 11. Figure 5 In some embodiments, the head-mounted display device 10 may also have, for example, Figure 1A The auxiliary headband 12 shown is connected to the bracket 110 and the front headband 13 to increase the stability of the head-mounted display device 10 worn on the user's head.

[0066] In summary, in this invention, the head-mounted display device uses a button to activate a coupling mechanism, giving the side headbands freedom of movement relative to the bracket, thereby adjusting the distance between the bracket and the front-end component. This allows the user to quickly and conveniently adjust the size of the head-mounted display device. Furthermore, when the button is released, a reset component tightens the side headbands via the coupling mechanism, continuously and subtly reducing the distance between the bracket and the front-end component, allowing the head-mounted display device to maintain a closer fit to the user's head. Moreover, the wearable components can be detachably assembled to the front-end component, enabling the wearable components to be assembled to different types of front-end components, ensuring that all types fit snugly against the user's face. In other words, a head-mounted display device with this type of wearable component not only allows for quick adjustment of the side headbands to fit different head shapes but also allows for easy fixation of the side headbands simply by releasing the button. Therefore, a head-mounted display device with this type of wearable component not only offers the advantages of quick on and off but also provides a stable fit on the user's head.
