The head-mounted display includes a face-sticking bracket 10, a shell 20 and a mainboard assembly, wherein shell connecting arms 21a and shell connecting arms 21b rotatably connected to the face-sticking bracket 10 are respectively provided on both sides of the shell 20, a lens is installed on the side of the shell 20 close to the face-sticking bracket 10, a display assembly is provided in the cavity surrounded by the shell 20, a visual window 12 is provided at the position of the lens corresponding to the face-sticking bracket 10, and a visual sensor for detecting the state of the user's eyes is provided on the face-sticking bracket 10. Usually, the visual sensor is arranged on the side wall of the visual window 12; it also includes a power device for driving the shell 20 to rotate relative to the face-sticking bracket 10, and the power device and the visual sensor are electrically connected to the mainboard assembly; specifically, the mainboard assembly is installed in the cavity surrounded by the shell 20, and of course, the mainboard assembly can also be installed on the face-sticking bracket 10.

[0021] The display component may include a display screen and / or a component for accommodating a display screen; for a PC-based head-mounted display and an all-in-one head-mounted display, the display component may include a display screen; for a mobile head-mounted display similar to a VR box, the display component may only include a component (or a cavity) for accommodating a display screen.

[0022] When wearing the head-mounted display, the face bracket 10 is tightly attached to the user's face, and the user's eyes are facing the visual window 12 of the face bracket 10. A visual sensor for detecting the state of the user's eyes is provided on the face bracket 10. When visual fatigue occurs or there are things to be dealt with in the real world, the user closes his eyes and maintains the time interval longer than a set time. When the visual sensor detects that the time interval of closing the eyes is longer than the set time, it will send an electrical signal to the mainboard component, and then the mainboard component will send a control signal to the power device to start working. The power device drives the shell 20 to rotate relative to the face bracket 10 until the visual window 12 is exposed. The eyes can look into the distance through the visual window 12 to relieve vision or deal with things; when you want to continue using the head-mounted display to enter the virtual world, similarly, close your eyes and maintain When the time interval of closing the eyes is greater than the set time, the visual sensor detects that the time interval of closing the eyes is greater than the set time, and another electrical signal is sent to the mainboard assembly again, and the mainboard assembly sends a start signal to the power device, and the power device drives the shell 20 to rotate in the opposite direction relative to the face-stick bracket 10 and rotate to the front of the visual window 12. In this way, whether it is to relieve visual fatigue or deal with things in the real world, there is no need to take off the head-mounted display. The head-mounted display of the present invention can detect the time interval of closing the eyes through the visual sensor, thereby sending an electrical signal to the mainboard assembly, and then the mainboard assembly sends a control signal to start working to the power device, and the power device drives the shell to rotate relative to the face-stick bracket 10 to realize the opening and closing of the head-mounted display, so there is no need to frequently wear and take off the head-mounted display.
