[0068] Please refer to Figure 1A and Figure 1B In this embodiment, the head mounted display device 10 includes a front assembly 12 and a wearable assembly 14. The wearable assembly 14 is connected to the front assembly 12 and is suitable for wearing the front assembly 12 on the user's face.

[0069] In this embodiment, the front-end component 12 may include an optical system (not shown) and components such as a protective housing, and may be provided with a display or be suitable for placing a display. The aforementioned display may be a built-in display or an external portable display (such as a smart phone, etc.), but the present invention is not limited to this. The type of the aforementioned display may be adjusted according to 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. In addition, the wearable component 14 may include any form of headband, and may also include any component or module for adjusting the length of the headband.

[0070] To cushion the pressure exerted by the wearable assembly 14 on the user's head, the head-mounted display device 10 includes at least one of a first padding module 100, a second padding module 200, and a third padding module 300. In this embodiment, the first padding module 100 is configured to abut the user's frontal bone. The second padding module 200 is configured to abut the user's occipital bone. The third padding module 300 is configured to abut the user's face, particularly around the user's eye sockets.

[0071] Please refer to Figure 2A 、 Figure 2B 、 Figure 3A and Figure 3B The first pad module 100 may include a first hard component 110, a first soft component 120 and a first fan 130. The first hard component 110 is connected to the wearable component 14 (eg Figure 1A and Figure 1B ). The first soft component 120 is connected to the first hard component 110 for contacting the user's skin and has a first rear flow channel 121. The first fan 130 is connected to the first rear flow channel 121 for introducing external air into the first rear flow channel 121. The first fan 130 is, for example, an axial flow fan, but is not limited thereto.

[0072] In this embodiment, the first rigid element 110 is made of, for example, plastic or other less compressible materials to provide support. The first rigid element 110 and a portion of the wearable component 14 may be integrally formed.

[0073] In the present embodiment, the material of the first soft element 120 is, for example, rubber, silicone, foam or other easily compressible materials to provide cushioning. The first soft element 120 may have a plurality of first cylinders 122. These first cylinders 122 can support the user's head. The first rear flow channel 121 extends between these first cylinders 122. The first soft element 120 has one or more first rear flow channel outlets 121a. These first rear flow channel outlets 121a are connected to the first rear flow channel 121 and are located on the surface of the first soft element 120 that does not contact the user's skin. Since the airflow from the first fan 130 will flow out from these first rear flow channel outlets 121a via the first rear flow channel 121 (i.e., through these first cylinders 122), the user will not feel stuffy in the area where the first soft element 120 contacts the skin.

[0074] In this embodiment, the first cushion module 100 further includes a first fabric layer 140. The first fabric layer 140 covers the first soft element 120. The first fabric layer 140 can be made of a breathable and cooling fabric. The first fabric layer 140 can be removably covered over the first soft element 120, allowing it to be removed for cleaning. More specifically, the airflow within the first rear flow channel 121 causes sweat absorbed by the first fabric layer 140 to evaporate, lowering the user's temperature. Therefore, the area where the first fabric layer 140 contacts the skin is less likely to feel stuffy.

[0075] Please refer to Figure 4A 、 Figure 4B 、 Figure 5A and Figure 5B The second pad module 200 may include a second hard component 210, a second soft component 220 and a second fan 230. The second hard component 210 is connected to the wearable component 14 (eg Figure 1A and Figure 1B ). The second soft component 220 is connected to the second hard component 210 for contacting the user's skin and has a second rear flow channel 221. The second fan 230 is connected to the second rear flow channel 221 for introducing external air into the second rear flow channel 221. The second fan 230 is, for example, an axial flow fan, but is not limited thereto.

[0076] In this embodiment, the second rigid element 210 is made of, for example, plastic or other less compressible materials to provide support. The second rigid element 210 and a portion of the wearable component 14 may be integrally formed.

[0077] In this embodiment, the material of the second soft element 220 is, for example, rubber, silicone, foam or other easily compressible materials to provide cushioning. The second soft element 220 may have a plurality of second cylinders 222. These second cylinders 222 can support the user's head. The second rear flow channel 221 extends between these second cylinders 222. The second soft element 220 has one or more second rear flow channel outlets 221a. These second rear flow channel outlets 221a are connected to the second rear flow channel 221 and are located on the surface of the second soft element 220 that does not contact the user's skin. Therefore, since the airflow of the second fan 230 will flow out from these second rear flow channel outlets 221a via the second rear flow channel 221 (i.e., through these second cylinders 222), the user will not feel stuffy in the area where the second soft element 220 contacts the skin.

[0078] In this embodiment, the second cushion module 200 further includes a second fabric layer 240. The second fabric layer 240 covers the second soft element 220. The second fabric layer 240 can be made of a breathable, cooling fabric. The second fabric layer 240 can be removably covered over the second soft element 220, allowing for easy cleaning. Specifically, the airflow within the second rear flow channel 221 causes sweat absorbed by the second fabric layer 240 to evaporate, lowering the user's skin temperature. Therefore, the area where the second fabric layer 240 contacts the skin feels less stuffy.

[0079] Please refer to Figure 6A 、 Figure 6B 、 Figure 7A 、 Figure 7B 、 Figure 8 and Figure 9 In this embodiment, the third pad module 300 may include a third hard component 310, a third soft component 320 and a plurality of third fans 330. The third hard component 310 is connected to the wearable component 14 (eg Figure 1A and Figure 1B The third soft component 320 is connected to the third hard component 310 to contact the user's skin 20 (as shown). Figure 8 ), and has a third rear flow channel 321. These third fans 330 are connected to the third rear flow channel 321 to introduce external air into the third rear flow channel 321.

[0080] In this embodiment, the third rigid component 310 has a front flow channel 311, and the third fans 330 are connected to the third rear flow channel 321 via the front flow channel 311. The third rigid component 310 may include a front cover 310a and a rear cover 310b, and the front cover 310a and the rear cover 310b are connected to each other to form the front flow channel 311, and the third rigid component 310 has a plurality of front flow channel outlets 311a to connect the front flow channel 311 with the third rear flow channel 321. The third fans 330 can be inserted into the front assembly 12 (such as Figure 1A and Figure 1B As shown in FIG, the third fan 330 is used to inject the external air or the internal air of the front assembly 12 into the third rear flow channel 321 via the front flow channel 311. When the internal air of the front assembly 12 is drawn out by the third fan 330, the temperature inside the front assembly 12 can also be reduced.

[0081] In this embodiment, the third soft element 320 has one or more third rear flow channel outlets 321a, which are connected to the third rear flow channel 321 and located on the surface of the third soft element 320 that contacts the user's skin. The third soft element 320 has one or more grooves 321c on its surface, with one or more of these third rear flow channel outlets 321a located within corresponding grooves 321c, allowing airflow to flow out of the third rear flow channel outlets 321a through the grooves 321c. These grooves 321c can be considered secondary flow channels. The third soft element 320 can extend from between the user's eyebrows around the user's eyes and to the user's cheeks, abutting the user's eye sockets. More specifically, because airflow flows through the grooves 321c, the user is less likely to feel stuffy in the area where the third soft element 320 contacts the skin.

[0082] In this embodiment, the third fans 330 have a plurality of air inlets 330a and air outlets 330b. The air inlets 330a are connected to the front-end components 12 (such as Figure 1A and Figure 1B As shown in FIG) and the space enclosed by the user's face and the external environment, and the air outlet 330b is connected to the third rear flow channel 321. Therefore, these third fans 330 can move the front end assembly 12 (as shown in FIG) Figure 1A and Figure 1B The air in the space enclosed by the front assembly 12 and the user's face is extracted and mixed with air drawn in from the outside environment. The air is then injected into the third rear flow channel 321 and discharged to the outside world through the third rear flow channel outlet 321a. As a result, the humidity and temperature in the space enclosed by the front assembly 12 and the user's face can be further reduced, making the user less likely to feel stuffy. Furthermore, because the air flows out through the groove 321c, the user is less likely to feel stuffy in the area where the third soft element 320 contacts the skin.

[0083] In another embodiment, the air inlet 330a can simultaneously draw in high-temperature air from the front assembly 12 and air from the outside environment, and inject them into the third rear flow channel 321. This can lower the temperature inside the front assembly 12. Furthermore, because the air flows out through the groove 321c, the user will feel less stuffy in the area where the third soft component 320 contacts the skin.

[0084] In this embodiment, the third padding module 300 may further include a third fabric layer 340 (eg Figure 9 (as shown). The third fabric layer 340 covers the third soft element 320. The third fabric layer 340 can be made of a breathable and cooling fabric. The third fabric layer 340 can be removably covered over the third soft element 320, allowing it to be removed for cleaning. More specifically, the air flowing out through the grooves 321c causes sweat absorbed by the third fabric layer 340 to evaporate, lowering the user's temperature. This reduces the feeling of stuffiness in the area where the third fabric layer 340 contacts the skin.

[0085] Please refer to Figure 10 , compared to Figure 8 In another embodiment, the third rigid component 310 (e.g., the front cover 310a of the third rigid component 310) may have one or more lateral airflow outlets 311d, and these lateral airflow outlets 311d are connected to the front flow channel 311. In addition, the third soft component 320 may have one or more lateral rear flow channel outlets 321d, and these lateral rear flow channel outlets 321d are connected to the third rear flow channel 321. The airflow blown out by these lateral airflow outlets 311d and the lateral rear flow channel outlets 321d can flow through the areas of the user's face not covered by the third soft component 320, such as the forehead, so that the user can feel a little cooler.

[0086] Please refer to Figure 11A 、 Figure 11B 、 Figure 12A 、 Figure 12B and Figure 13 , which illustrates another embodiment and Figure 6A The embodiments of are roughly the same, but the differences between the two are as follows. First, in Figure 6A In the embodiment described above, the third fans 330 are located above the user's eyes. However, in this embodiment, the third fans 330 are located on both cheeks of the user, and the third rigid component 310 has a plurality of fan covers 310c fixed to the front cover 310a to secure the third fans 330. In another embodiment, the fan covers 310c may also be integrated into a single component.

[0087] Furthermore, in this embodiment, the third soft element 320 has a thickened portion 323, and the thickened portion 323 is distributed along the third rear flow channel 321. Therefore, when the third soft element 320 is squeezed or worn, the thickened portion 323 will ensure that the third rear flow channel 321 is not interrupted and remains unobstructed.

[0088] In addition, in this embodiment, there are two third rear flow channels 321 and two thickened portions 323. Each third rear flow channel 321 extends from the user's forehead to the user's cheek, and each thickened portion 323 is located outside the corresponding third rear flow channel 321. There are two third fans 330, and each of these third fans 330 is connected to each of these third rear flow channels 321.

[0089] The third fans 330 have a plurality of air inlets 330a and air outlets 330b. The air inlets 330a are connected to the front-end components 12 (such as Figure 1A and Figure 1B As shown in FIG) and the space enclosed by the user's face and the external environment, and the air outlet 330b is connected to the third rear flow channel 321. Therefore, these third fans 330 can move the front end assembly 12 (as shown in FIG) Figure 1A and Figure 1B The air in the space enclosed by the front assembly 12 and the user's face is extracted and mixed with air drawn in from the outside environment. The air is then injected into the third rear flow channel 321 and discharged to the outside world through the third rear flow channel outlet 321a. As a result, the humidity and temperature in the space enclosed by the front assembly 12 and the user's face can be further reduced, making the user less likely to feel stuffy. Furthermore, because the air flows out through the groove 321c, the user is less likely to feel stuffy in the area where the third soft element 320 contacts the skin.

[0090] In this embodiment, the third lining module 300 may also include a third fabric layer (not shown).

[0091] The third fabric layer covers the third soft element 320. The third fabric layer can be made of breathable and cool fabric.

[0092] The third fabric layer can be detachably covered with the third soft element 320 so that it can be removed for cleaning. More specifically, the air flowing out through the grooves 321c causes the sweat absorbed by the third fabric layer to evaporate, thereby reducing the temperature. Therefore, the user will feel less stuffy in the area where the third fabric layer contacts the skin.

[0093] In summary, the soft component of the pad module of the head mounted display device is connected to the hard component and is used to contact the user's skin, and the fan drives the airflow through the rear flow channel of the soft component to provide a heat dissipation effect.
