Description

head mounted display

The present invention relates to a display device, and more particularly, to a head-mounted display device.

With the increasing development of the technology industry, the types, functions and ways of use of display devices are becoming more and more diverse, and head-mounted display devices that can be directly worn on the user's body are also born accordingly. There are quite a lot of types of head-mounted display devices. Taking head-mounted display devices such as eye mask type as an example, after wearing such a display device, in addition to seeing stereoscopic images, the images will follow the user's head. The parts are rotated and changed, which can provide users with a more immersive experience.

The front assembly of the head-mounted display device is worn on the face of the user through the wearing assembly, so that the display module of the front assembly can project a display image toward the eyes of the user. In order to cushion the pressure exerted by the wearing assembly on the user's head, a pad may be provided between the wearing assembly and the user's head. However, the pad tends to make the user feel stuffy after prolonged use.

The present invention provides a head-mounted display device, the pad of which has the function of active heat dissipation.

The head-mounted display device of the present invention includes a front-end component, a wearing component and a pad module. The wearing component is connected to the front end component and is suitable for wearing the front end component to the user's face. The gasket module includes a hard element, a soft element and a fan. The hard element is attached to the wearable assembly. The soft element is connected to the hard element to contact the user's skin and has a rear flow channel. The fan communicates with the rear runner.

Based on the above, the soft element is connected to the hard element to contact the user's skin, and the fan drives the airflow to flow through the rear channel of the soft element to provide heat dissipation.

Please refer to FIGS. 11A , 11B, 12A, 12B and 13 , another embodiment shown there is substantially the same as the embodiment of FIG. 6A , and the differences are as follows. First, in the embodiment of FIG. 6A , the third fans 330 are located above the eyes of the user, but in this embodiment, the third fans 330 are respectively located on the two cheeks of the user, and the third hard element 310 has a plurality of fan covers 310c fixed to the front cover 310a to fix the third fans 330 . In another embodiment, the fan covers 310c can also be integrated into a single component.

In addition, 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 will not be interrupted and remain unobstructed as much as possible.

In addition, in the present embodiment, the number of the third rear flow channels 321 is two, the number of the thickened portions 323 is two, and each third rear flow channel 321 extends from the user's forehead to the user's cheek, And each thickened portion 323 is distributed outside the corresponding third rear runner 321 . The number of the third fans 330 is two, and the third fans 330 are respectively connected to the third rear flow channels 321 .

The third fans 330 have a plurality of air inlets 330a and an air outlet 330b. The air inlets 330a are respectively connected with the space enclosed by the front end assembly 12 (as shown in FIG. 1A and FIG. 1B ) and the user's face and with the outside world. The environment is communicated, and the air outlet 330b is communicated with the third rear flow channel 321 . Therefore, the third fans 330 can extract the air in the space surrounded by the front end assembly 12 (as shown in FIG. 1A and FIG. 1B ) and the user's face, mix the air inhaled by the external environment, and then inject the air into the third fan 330 . The three rear runners 321 are then discharged to the outside from these third rear runner outlets 321a. Therefore, the humidity and temperature in the space surrounded by the front end assembly 12 and the user's face can be further reduced, so that the user does not feel stuffy. At the same time, since the air flows out through the groove 321c, the user will not feel stuffy in the area where the third soft element 320 is in contact with the skin.

In this embodiment, the third pad module 300 may also include a third fabric layer (not shown). The third fabric layer covers the third soft element 320 . The third fabric layer can be a breathable and cool fabric. The third fabric layer can cover the third soft element 320 in a removable manner so as to be removed for cleaning. In more detail, the gas flowing out through the grooves 321c promotes the evaporation of the sweat absorbed by the third fabric layer to reduce the temperature, so the user will not feel stuffy in the area where the third fabric layer contacts the skin.

To sum up, the soft element of the cushion module of the head-mounted display device is connected to the hard element for contacting the user's skin, and the fan drives the airflow to flow through the rear channel of the soft element to provide heat dissipation.
