[0021] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0022] Figure 1 It is a schematic diagram of the head outlines of various different users. Figure 1 The head contours of different users at the forehead position are presented simultaneously. Figure 1It can be seen that although the contour lines of the heads of different users vary to varying degrees, it is still possible to find a position on both sides of the forehead where these contour lines almost pass, such as the circled area A in the figure.

[0023] Figure 2A Schematic diagram of the head mounted display device in use according to an embodiment of the present invention. Figure 2A The head-mounted display device 50 of this embodiment includes a display portion 52 and a support frame 100. The support frame 100 of this embodiment includes a fixing portion 110, a platform portion 115, two cantilevers 120, and two fitting pads 130. The fixing portion 110 is used to be mounted on the display portion 52 of the head-mounted display device 50. The platform portion 115 rests on the top of the display portion 52 of the head-mounted display device 50. A first end 122 of each cantilever 120 is fixed to the fixing portion 110. Each fitting pad 130 is pivotally connected to a second end 124 of the corresponding cantilever 120.

[0024] In the head mounted display device 50 of this embodiment, the positions of the two pivot points P10 correspond exactly to Figure 1 The circled area A in the figure is where the contour of most users' heads passes. Furthermore, because the fitting pad 130 for fitting the user's forehead is pivotally connected to the cantilever 120, the fitting pad 130 can rotate to adapt to the contours of different users' heads, providing better contact with the user's head, helping to improve the user's comfort while wearing the head-mounted display device and further increasing its stability when worn on the user's head.

[0025] Figure 2B yes Figure 2A A schematic side view of a head mounted display device. The display unit 52 is represented by a dotted frame only. Figure 2A and Figure 2B Because the platform portion 115 rests against the top of the display portion 52, the support frame 100 can be prevented from flipping relative to the display portion 52 of the head-mounted display device 50, further enhancing its stability when worn on the user's head. Furthermore, the support frame 100 of this embodiment may include a fixing pin 150 for insertion into the display portion 52 of the head-mounted display device 50, further enhancing the stability of the entire device.

[0026] In this embodiment, the distance between the two fitting pads 130 and the two pivoting points P10 of the two cantilevers 120 is between 6 cm and 11 cm. The distance D10 between the two pivoting points P10 is between 6 cm and 11 cm.

[0027] In this embodiment, when the head-mounted display device 50 is worn on the user's head, the two pivot points P10 are located on a vertical plane S10 where the user's eyes are located. In other words, the two pivot points P10 and the user's eyes are located on the same plane, and this plane is a vertical plane, namely, the vertical plane S10.

[0028] In other embodiments of the present invention, when the head-mounted display device 50 is worn on a user's body, the distance between the pivot point P10 and the vertical plane S10 where the user's eyes are located is between -1.1 cm and 1.1 cm. In other words, the two pivot points P10 can be located in front of or behind the vertical plane S10, and the distance between the pivot points P10 and the vertical plane S10 is between -1.1 cm and 1.1 cm.

[0029] Figures 3A to 3D yes Figure 2A Schematic diagram of the state of the head-mounted display device support frame and the heads of four different users. Please refer to Figures 3A to 3D Although the head shapes of the users in these figures are different, because the fitting pad 130 can rotate, it can better contact the user's head, which helps to improve the comfort of the user wearing the head-mounted display device and further increase its stability when worn on the user's head.

[0030] Figure 4 is a schematic diagram of a head mounted display device according to another embodiment of the present invention. Figure 4 In another embodiment of the present invention, the head-mounted display device 60 further includes a light shield 64 assembled to the fixing portion 110 of the support frame 100. The light shield 64 is used to surround the space between the display portion 52 of the head-mounted display device 60 and the user's eyes to reduce the influence of external light and enhance the immersive feeling when viewing images. The light shield 64 is flexible to cover the user's eyes. In this embodiment, the material of the light shield 64 is, for example, sponge, foam material, or other flexible materials, but the present invention is not limited thereto. In addition to providing a light shielding effect, the flexible light shield 64 also provides the effect of supporting the display portion 52 of the head-mounted display device 60. Specifically, the upper side of the light shield 64 can be placed against the upper side of the user's eyes, such as the user's forehead bone. The lower side of the light shield 64 can be placed against the lower side of the user's eyes, such as the user's cheekbone. More specifically, because the lower side of the visor 64 can rest against the lower sides of the user's eyes, the pressure exerted on the user's nose by the head-mounted display device 60 can be reduced, thereby improving the user's wearing comfort. Opposite sides of the visor 64 can rest against opposite sides of the user's eyes, such as the outer corners of the user's eyes.

[0031] Figure 5AFIG. 1 is a schematic diagram of a support frame in an exploded state according to another embodiment of the present invention. Figure 5B yes Figure 5A Schematic diagram of the support frame assembly state. Please refer to Figure 5A and Figure 5B , the support frame 200 of another embodiment of the present invention also includes a soft pad 140 for contacting the user's head. The soft pad 140 has a slide groove G10. The fitting pad 130 of the support frame 200 is detachably slidable in the slide groove G10. The fitting pad 130 and the cantilever 120 are pivotally connected to each other through an opening OP10 of the slide groove G10. Because the soft pad 140 is flexible, it can be deformed according to the user's head shape and provide a comfortable contact feeling. During the deformation of the soft pad 140, the fitting pad 130 can slide in the slide groove G10, so it will not limit the deformation of the soft pad 140. In addition, the fitting pad 130 can also be taken out of the slide groove G10, so the user can clean the soft pad 140 and maintain hygiene. For example, the soft pad 140 may include a fixing pad 142 and a contact pad 144. The fixing pad 142 has a sliding groove G10 , and the contact pad 144 is attached to a side of the fixing pad 142 that does not have the opening OP10 .

[0032] Figure 6 FIG is a schematic diagram of a head mounted display device according to another embodiment of the present invention. Figure 6 The head mounted display device 70 of this embodiment is roughly the same as Figure 2A The head-mounted display device 70 of this embodiment is similar to the head-mounted display device 50, and only the differences are described here. The head-mounted display device 70 of this embodiment also includes a headband module 72, which is detachably assembled to the display unit 52 on opposite sides. When the display unit 52 and headband module 72 are assembled together, the head-mounted display device 70 can be stably fixed to the user's head even when the user makes more intense movements, without the risk of it falling or even being damaged.

[0033] In this embodiment, the distance between the two opposite sides of the headband module 72 is adjustable. That is, after the display portion 52 and the headband module 72 are assembled, the distance between the two opposite sides of the headband module 72 can be adjusted so that users with different head circumferences can wear the head-mounted display device 70 comfortably and securely.

[0034] In this embodiment, the headband module 72 is detachably connected to the two brackets 52A of the display unit 52. In other usage scenarios, the headband module 72 can be removed. For example, when watching a video or engaging in other static activities, the user can enjoy a more comfortable and convenient experience by removing the headband module 72, as strong fixing force is not required. In other embodiments, the brackets 52A can also be connected to other expanded functional components, thereby making the head-mounted display device 70 even more convenient to use.

[0035] In summary, in the support frame and head-mounted display device of the present invention, because the support frame contacts the user's head with two rotatable fitting pads, it can be rotated to accommodate different head shapes, helping to improve the user's comfort when wearing the head-mounted display device and thereby increase its stability when worn on the user's head. Furthermore, the platform portion rests against the top of the display portion, preventing the support frame from flipping relative to the display portion of the head-mounted display device, further increasing its stability when worn on the user's head.
