The utility model provides a VR head-mounted display device with multiple air bags and self-adaptive pressure regulation, as shown in Figure 1 and Figure 2 The utility model discloses a VR head-mounted display device with multiple air bags and self-adaptive pressure regulation, which comprises a display device 1, two symmetrical wearing frames 2 fixedly connected to one end of the display device 1, and at least three mounting plates 21 rotatably connected to each other, wherein one side of the mounting plate 21 is provided with two fixed assemblies 3, and the fixed assembly 3 comprises a fixed air bag 32 arranged on one side of the mounting plate 21.

[0033] During wearing, the three mounting plates 21 are arranged around the head of the user after being rotated, and the three mounting plates 21 are respectively arranged on the front and rear sides of the temples of the user and the back of the head of the user. Six fixed assemblies 3 are arranged in one group for every three fixed assemblies 3. During wearing, the fixed air bags 32 in the two groups of fixed assemblies 3 are alternately inflated and deflated. Only one group of fixed air bags 32 is in contact with the head of the user in each working cycle, thereby reducing the contact points between the wearing frame 2 and the head of the user in the working cycle.

The first air pump 33 is used for inflating and deflating the inside of the fixed air bag 32.

[0035] In order to accurately control the air flow of the fixed air bag 32, in order to avoid excessive inflation of the fixed air bag 32 to extrude the user's head, the inside of the mounting cylinder 31 is fixedly connected with an air pressure sensor 34, the air pressure sensor 34 is used to detect the internal air pressure of the fixed air bag 32, and the air pressure sensor 34 can also be electrically connected with the controller in the display device 1.

[0036] In addition, the inside of the mounting plate 21 is also provided with two heat dissipation assemblies 4, the heat dissipation assembly 4 is paired with the fixed assembly 3, when one fixed assembly 3 works, the heat dissipation assembly 4 paired with it is used to dissipate heat at the contact part of the fixed air bag 32 and the user's head;

[0037] In implementation, referring to Figure 4 , the heat dissipation assembly 4 includes a No. 2 air pump 41 fixedly connected inside the mounting plate 21, the No. 1 air pump 33 and the No. 2 air pump 41 are electrically connected with the air pressure sensor 34, the air outlet end of the No. 2 air pump 41 is communicated in the inside of the mounting cylinder 31, one side of the mounting cylinder 31 is provided with two air outlets 311, the two air outlets 311 are respectively and symmetrically arranged on both sides of the fixed air bag 32, when the air pressure sensor 34 controls the No. 1 air pump 33 to inflate the fixed air bag 32, it can also control the No. 2 air pump 41 to start synchronously to blow air to both sides of the fixed air bag 32 for heat dissipation, on the contrary, when the fixed air bag 32 deflates, the No. 2 air pump 41 is closed synchronously;

[0038] In order to avoid foreign matters from the outside entering the inside of the mounting cylinder 31 from the air outlet 311, referring to Figure 4 and Figure 5 , the inside of the mounting cylinder 31 is fixedly connected with two fixed pipes 44, the inside of the fixed pipe 44 is slidably connected with a piston plate 45, the bottom of the piston plate 45 and the fixed pipe 44 are fixedly connected with a reset spring 46, the top of the piston plate 45 is fixedly connected with a support rod 47, the top of the support rod 47 is rotatably connected with a sealing plate 48, the sealing plate 48 is rotatably connected on the inside of the air outlet 311, the sealing plate 48 can block the air outlet 311 when the fixed assembly 3 does not work, so as to realize the effect of preventing foreign matters from entering the inside of the mounting cylinder 31, the reset spring 46 can only support the piston plate 45, the support rod 47 and the sealing plate 48;

[0039] In addition, the inside of the fixed pipe 44 is provided with a pressure adjusting cavity 441, referring to Figure 5 , the connecting position of the bottom of the reset spring 46 and the fixed pipe 44 is provided with a communication hole, so as to ensure that the air pressure in the fixed pipe 44 is always synchronized with the outside air pressure;

[0040] When implemented in the above manner, referring to Figure 6At this time, the second air pump 41 no longer continuously blows air from the air outlet 311, but first fills the inside of the mounting cylinder 31 with gas. When the air pressure in the mounting cylinder 31 exceeds the elastic force of the return spring 46, the return spring 46 is compressed, the support rod 47 is lowered to rotate the sealing plate 48, thereby opening the air outlet 311. The air flow is obliquely directed to the surface of the user's head by the guiding effect of the sealing plate 48, thereby improving the heat dissipation range and achieving the effect of periodic air blowing for heat dissipation, thereby avoiding long-term direct blowing of air to the user's head.

[0041] Further, in order to further improve the heat dissipation effect in a hot environment, referring to Figure 4 As shown, a plurality of refrigeration fins 42 are fixedly connected inside the mounting cylinder 31, and a plurality of heat dissipation fins 43 are fixedly connected inside the mounting plate 21. The refrigeration fins 42 can be semiconductor refrigeration fins 42, with the cold end located inside the mounting cylinder 31 and the hot end penetrating the inner wall of the mounting cylinder 31 and fixedly connected with one side of the heat dissipation fin 43 to achieve heat exchange. At the same time, cooperating with the periodically opened sealing plate 48, the refrigeration time of the gas blown by the second air pump 41 in the mounting cylinder 31 is increased, thereby further improving the cooling effect of the air flow and improving the heat dissipation effect of the device.

[0042] Referring to Figure 3 As shown, the mounting cylinder 31 is rotationally connected with a sealing cover 35. When the sealing cover 35 is closed, it is sealed with the mounting cylinder 31. When opened, it is convenient for the user to regularly clean the inside of the mounting cylinder 31.

[0043] The working principle of the device is as follows:

[0044] After the user holds the device as a whole, the device is placed in a suitable position on the head, so that the display device 1 can block the user's eyes. Then the user pulls the deformed plate 22 with his hand to make the three mounting plates 21 surround his head. Then the controller in the display device 1 controls a group of air pressure sensors 34. After the group of air pressure sensors 34 are controlled to start, the corresponding first air pump 33 and second air pump 41 respectively inflate the fixed air bag 32 and the mounting cylinder 31. After the air pressure sensor 34 senses that the fixed air bag 32 is inflated to an appropriate amount, it controls the first air pump 33 to close, and the second air pump 41 continues to inflate the mounting cylinder 31.

[0045] During the continuous inflation of the second air pump 41, the gas will first accumulate in the mounting cylinder 31. The gas is cooled by the refrigeration fins 42. Whenever the pressure of the air pressure in the mounting cylinder 31 exceeds the elastic force of the return spring 46, the piston plate 45 will compress the return spring 46, and drive the support rod 47 and the sealing plate 48 to move, thereby opening the air outlet 311. At this time, the refrigerated gas in the mounting cylinder 31 is obliquely blown out from the air outlet 311 to the surface of the user's head, thereby achieving the effect of heat dissipation.

[0046] Whenever wearing a working cycle, the controller in the display device 1 will control two sets of fixed components 3 and heat dissipation components 4 alternately, in the stability of the device wearing, also avoid the device and the user head contact point too much in the wearing process and lead to the user feels hot situation appears, improve the wearing comfort of the device.
