The supporting member 2 is connected to the display member 1 to form an accommodating space C for the user to wear, and supports and positions the display member 1 on the eyes of the user. The invention does not limit the shape of the supporting member 2, the supporting member 2 and the display member 1 can form a glasses shape as shown in the figure, or a full-cover or half-cover type helmet shape, or various shapes such as glasses and a head fixing belt; for example, but not limited to, the supporting member 2 of the present embodiment may be two long rod-shaped members pivotally connected to the left and right ends of the display member 1, respectively, so that the two members can rest on the left and right ears of the user; the inner surface 11 of the display element 1 faces the accommodating space C, and the surface of the supporting element 2 facing the accommodating space C is close to or even can partially contact the head of the user.
Referring to fig. 1 and 3, the support 2 is provided with an exhaust port 21 at a position far away from the display 1, the fan 3 is disposed in the support 2, the shape of the fan 3 is not limited, the fan 3 has an air outlet 31 and an air inlet 32, the air outlet 31 faces the exhaust port 21 of the support 2, and the air inlet 32 can be communicated with the accommodating chamber 13 of the display 1.
Referring to fig. 1 and 2, in the present embodiment, at least a portion of the supporting member 2 extends along the X direction, and the exhaust port 21 is disposed at a position of the supporting member 2 away from the display member 1 in the X direction; that is, the exhaust port 21 may be disposed on an end surface of the supporting member 2 away from the display member 1 in the X direction, or on an upper end surface or a lower end surface of the supporting member 2 in the Z direction, or on a surface of the supporting member 2 facing away from the accommodating space C, which is not limited in the disclosure. In addition, since the heat source H of the present embodiment is selectively disposed in the chamber 13 of the display 1, the supporting member 2 may be provided with an air inlet 22 adjacent to the display 1, and the air inlet 22 faces the opening 14 of the display 1, so as to guide out the high-temperature air around the heat source H.
Referring to fig. 1 and 3, according to the above structure, the head-mounted display apparatus of the present invention can operate by actuating the fan 3, so that the high-temperature air accumulated at the heat source H can flow to the air inlet 32 of the fan 3 through the opening 14 of the display 1 and the air inlet 22 of the support 2, and then is guided to the air outlet 21 of the support 2 from the air outlet 31 of the fan 3 to be exhausted to the outside, thereby ensuring that the head-mounted display apparatus can operate at a proper working temperature without being heated to a degree that causes discomfort to a user, and avoiding an overheat crash.
In addition, referring to fig. 4, the head-mounted display apparatus of the embodiment may further include a heat conducting member 8, where the heat conducting member 8 may be, for example, a heat pipe or a vapor chamber, one end of the heat conducting member 8 extends into the accommodating chamber 13 of the display member 1 to be connected to the heat source H, and the other end of the heat conducting member 8 extends into the supporting member 2 through the opening 14 of the display member 1 and the air inlet 22 of the supporting member 2. Accordingly, the heat conducting member 8 can rapidly guide the heat generated by the heat source H out of the accommodating chamber 13 and transmit the heat to the position closer to the fan 3, so that the temperature rise of the display member 1 can be more effectively reduced.
Referring to fig. 5, a head-mounted display apparatus according to a second embodiment of the present invention is shown, which is substantially the same as the first embodiment, and mainly differs therefrom in that: the second embodiment of the present invention provides the heat source H of the head-mounted display apparatus in one support 4.
In detail, the support 4 is provided with an exhaust port 41 at a position away from the display 1; the air outlet 41 may be disposed on an end surface of the supporting member 4 away from the display element 1 in the X direction, or on an upper end surface or a lower end surface of the supporting member 4 in the Z direction, or on a surface of the supporting member 4 facing away from the accommodating space C, which is not limited in the present invention. The support 4 is additionally provided with an air inlet 42 between the display 1 and the air outlet 41; the air inlet 42 can also be selectively disposed on the upper end surface or the lower end surface of the supporting member 4 in the Z direction, or preferably disposed on the surface of the supporting member 4 facing away from the accommodating space C, so as to prevent the air inlet 42 from being shielded by the head of the user. In the X direction, the heat source H is preferably disposed between the air inlet 42 and the air outlet 41 of the support 4. Accordingly, when the fan 3 is operated, the external air with relatively low temperature can flow into the supporting member 4 through the air inlet 42 and flow through the heat source H to lower the operating temperature thereof, and the air with relatively high temperature is guided by the fan 3 to be discharged to the outside through the air outlet 41.
In the X direction, the fan 3 may be disposed between the heat source H and the exhaust port 41 of the support 4 as shown in fig. 5; alternatively, as shown in fig. 6 and 7, the heat source H may be disposed between the fan 3 and the exhaust port 41 of the support 4, and particularly, the air inlet 32 of the fan 3 may be opposite to the air inlet 42 of the support 4, so as to improve the smoothness of flow guiding and the heat dissipation efficiency of the heat source H.
Referring to fig. 8, a heat source H of the head-mounted display apparatus is disposed in the display 1 or in the support 5, the support 5 is provided with an air outlet 51 away from the display 1, and the support 5 is further provided with an air inlet 52 on a surface facing away from the accommodating space C. One end of a heat-conducting member 8 is connected to the heat source H, and the other end of the heat-conducting member 8 is opposite to the air inlet 52 of the support member 5.
Accordingly, the heat conducting member 8 can rapidly conduct the heat generated by the heat source H to the other end of the heat conducting member 8, so that when the fan 3 is in operation, the external relatively low-temperature air can pass through the air inlet 52 and directly blow toward the other end of the heat conducting member 8 to rapidly reduce the temperature of the heat conducting member 8, and the relatively high-temperature air is guided by the fan 3 to be exhausted from the air outlet 51 of the supporting member 5 to the outside. Alternatively, the other end of the heat conducting member 8 may also extend into the fan 3, or preferably extend between the fan 3 and the air outlet 51 of the supporting member 5, so that the fan 3 can directly and rapidly cool the other end of the heat conducting member 8, thereby achieving good heat dissipation efficiency.
Referring to fig. 9 and 10, a head mounted display device according to a fourth embodiment of the present invention is shown, which is substantially the same as the first embodiment, and mainly differs therefrom in that: the fourth embodiment of the present invention makes the supporting member 6 include one extending portion 6a and one adjusting portion 6b that are relatively pivotable.
In detail, the extending portion 6a of the supporting member 6 extends from the display member 1 along the aforementioned X direction, one end of the extending portion 6a is connected to the display member 1, the adjusting portion 6b is pivotally connected to the other end of the extending portion 6a, and the supporting member 6 is provided with an air outlet 61 at one end of the adjusting portion 6b away from the extending portion 6 a; the air outlet 61 may be disposed on an end surface of the adjusting portion 6b at an end far from the extending portion 6a, or on a surface of the adjusting portion 6b facing away from the accommodating space C, or on any end surface of the adjusting portion 6b in the X direction in fig. 9, which is not limited in the present invention.
In the present embodiment, the extension portion 6a has a first flow passage 62 therein, the adjustment portion 6b has a second flow passage 63 therein, and the exhaust port 61 communicates with the second flow passage 63. A fan 3 can be disposed in the first flow channel 62 or the second flow channel 63, and the air outlet 31 of the fan 3 faces the air outlet 61. The extending portion 6a is provided with an air inlet 64, the air inlet 64 is communicated with the first flow channel 62, and the position of the air inlet 64 can be determined according to the position of the heat source H of the head-mounted display device; for example, in the present embodiment, the heat source H is selectively disposed in the accommodating chamber 13 of the display 1, so the air inlet 64 can be disposed at one end of the extending portion 6a connected to the display 1, and the air inlet 64 faces the opening 14 of the display 1, so that the first flow channel 62 can communicate with the accommodating chamber 13. In other embodiments, the heat source H is optionally disposed inside the supporting member 6, and the air inlet 64 is optionally disposed on a surface of the extending portion 6a facing away from the accommodating space C. Alternatively, the number of the air outlets 61 or air inlets 64 of the supporting member 6 may be multiple, for example, one of the air inlets 64 is communicated with the accommodating chamber 13, and the other air inlet 64 is disposed on a surface of the extending portion 6a facing away from the accommodating space C, or disposed on any end surface of the extending portion 6a in the Z direction in fig. 9, so as to enhance the smoothness of the air flow flowing through the first flow channel 62 and the second flow channel 63.
The other end of the extending portion 6a is provided with a first airflow port 65, the first airflow port 65 is communicated with the first flow channel 62, and the first airflow port 65 can be arranged on the surface of the extending portion 6a facing away from the accommodating space C; the adjusting portion 6b is provided with a second airflow port 66, the second airflow port 66 is communicated with the second flow channel 63, and the second airflow port 66 can be disposed on a surface of the adjusting portion 6b facing the accommodating space C. Accordingly, the adjusting portion 6b is pivotally connected to the extending portion 6a, and maintains the second airflow opening 66 facing the first airflow opening 65.
Referring to fig. 9 and 11, according to the above structure, the head-mounted display apparatus of the present invention can operate by actuating the fan 3, such that the high-temperature air accumulated at the heat source H can flow into the first flow channel 62 through the opening 14 of the display element 1 and the air inlet 64 of the extension portion 6a, and flow into the second flow channel 63 from the first air flow port 65 of the extension portion 6a through the second air flow port 66 of the adjustment portion 6b, and then be guided to the air outlet 61 of the adjustment portion 6b to be discharged to the outside. Therefore, the head-mounted display device of the embodiment can not only operate at a proper working temperature to avoid discomfort or overheating and death of the user, but also mount the extension portion 6a of the support member 6 on the ear of the user and discharge the hot air at a position far away from the ear of the user by the adjustment portion 6b of the support member 6, so that the ear of the user has no thermal sensation and the use comfort can be further improved.
Moreover, the fan 3 is preferably disposed in the second flow channel 63, and more preferably, the fan 3 is disposed at the exhaust port 61 closer to the adjusting portion 6b, so as to reduce the operating volume of the fan 3 heard by the user.
