The present disclosure relates to a field of a head-mounted device, and especially to an air eye cover and a head-mounted device adopting the air eye cover.
Virtual Reality (VR) refers to producing a virtual world of a three-dimensional space through a computer simulation, providing sensorial simulations such as visual simulation, auditory simulation or tactile simulation for a user, and hence allowing the user to observe objects in the three-dimensional space just like being personally on the scene. In recent years, along with continuous developments of VR technology, distinctive head-mounted display devices are progressively rolled out by a plurality of VR related companies. In order to improve realness of the sensorial simulation, the head-mounted display devices configured to present the virtual reality scene is required to have a great light-blocking effect. Meanwhile, as the user needs to wear the head-mounted display device for a long time when experiencing VR films or games by the head-mounted display devices, a great comfort in the wearing process should be taken in consideration, so as to improve the user experience further. At present, among the current head-mounted display devices, an eye cover contacting face is mostly made of rubber or cloth filled with elastic materials such as sponge. However, as facial features of the users are not totally same, a surface of the eye cover part of the current head-mounted display device cannot be changed flexibly in shape according to a change of the facial feature of the user, thus causing a bad light-blocking effect of the head-mounted display device, and hence influencing a presentation effect of VR films or games. Meanwhile, as the user needs to wear the head-mounted display device all along in the processes of experiencing VR films or games, how to improve the comfort of the head-mounted display device is also a problem to be solved.
In consideration of the above-mentioned problems existing in the related art, embodiments of the present disclosure provide an air eye cover, so as to improve a light-blocking effect and a wearing comfort and hence to promote a user experience.
In addition, embodiments of the present disclosure further provide a head-mounted device adopting the above air eye cover.
The air eye cover includes a fixed gasbag, an air-filling control device and an air-exhausting control device. The air-filling control device and the air-exhausting control device both electrically connect to the control device. The fixed gasbag includes a first air inlet and a first air outlet.

The first massage portion 121 is provided with a first via hole 1211, the second massage portion 123 is provided with a second via hole 1231. A second reversed V-shaped structure 125 is formed at a position where the first massage portion 121 and the second massage portion 123 connect to each other. When the massage gasbag 12 is embedded in the fixed gasbag 11, the first via hole 1211 aligns with the first through hole 1111, the second via hole 1231 aligns with the second through hole 1131, and the second reversed V-shaped structure 125 perches on the first reversed V-shaped structure 115. It could be understood that, the massage gasbag 12 may be embedded in the fixed gasbag 11 completely and penetrate the fixed gasbag 11, or partially embedded in the fixed gasbag 11 at a side of the fixed gasbag 11 facing the human face. When the massage gasbag 12 is completely embedded in the fixed gasbag 11 and penetrates the fixed gasbag 11, a through hole (not illustrated in the drawings) corresponding to an outline of the massage gasbag 12 needs to be reserved in the fixed gasbag 11.

It could be understood that, the air pump 132, the air-filling solenoid valve 134 and the air-filling switch valve 135 all electrically connect to the control device 16. When the control device 16 controls the air pump 132 to switch on so as to suck in air and the air-filling solenoid valve 134 is opened, the air enters the fixed gasbag 11 or the massage gasbag 12. When the control device 16 controls the air-filling switch valve 135 to switch to the first output end 1353 so as to output air thereat, the air enters the fixed gasbag 11 from the first output end 1353 through the first air-filling check valve 136 and the first air inlet 1101. When the control device 16 controls the air-filling switch valve 135 to switch to the second output end 1355 so as to output air thereat, the air enters the massage gasbag 12 from the second output end 1355 through the second air-filling check valve 137 and the second air inlet 1201.
Specifically, the air-filling control device 13 may further include the air release valve 133 provided between the air pump 132 and the air-filling solenoid valve 134 and configured to release air when an air input volume is too large. The air release valve 133 may be a mechanical valve or an electronic control valve. When the air release valve 133 is a mechanical valve, if a pressure in a pipe is larger than an opening pressure value of the mechanical valve, the air release valve 133 is opened to release the air. When the air is released such that the pressure value recovers to a standard value, that is the pressure value is less than the opening pressure value, the air release valve 133 comes into a closed state. The air release valve 133 is used as a protection measure when a too large amount of air exists between the air pump 132 and the air-filling solenoid valve 134.
The air-exhausting control device 15 includes a first air-exhausting check valve 151, a second air-exhausting check valve 152, an air-exhausting switch valve 153, an air-exhausting solenoid valve 154 and a main air outlet 155. The air-exhausting switch valve 153 includes a first input end 1531, a second input end 1533 and an output end 1535. The first input end 1531 hermetically connects to the first air outlet 1103 via the first air-exhausting check valve 151. The second input end 1533 hermetically connects to the second air outlet 1203 via the second air-exhausting check valve 152. The output end 1535 hermetically connects to the main air outlet 155 via the air-exhausting solenoid valve 154.
It could be understood that the air-exhausting switch valve 153 and the air-exhausting solenoid valve 154 both electrically connect to the control device 16. When the control device 16 controls the air-exhausting solenoid valve 154 to open, the air in the fixed gasbag 11 or the massage gasbag 12 can be exhausted through the main air outlet 155. When the control device 16 controls the air-exhausting switch valve 153 to switch to the first input end 1531 so as to input air thereat, the air in the fixed gasbag 11 is exhausted out of the main air outlet 155 through the first air-exhausting check valve 151, the first input end 1531, the output end 1535 and the air-exhausting solenoid valve 154. When the control device 16 controls the air-exhausting switch valve 153 to switch to the second input end 1533 so as to input air thereat, the air in the massage gasbag 12 is exhausted out of the main air outlet 155 through the second air-exhausting check valve 152, the second input end 1533, the output end 1535 and the air-exhausting solenoid valve 154. In the present embodiment, the air release valve 133, the air-filling solenoid valve 134 and the air-exhausting solenoid valve 154 are normally-open elements when de-energized, that is, the de-energization of the valve corresponds to the open of the valve, and the energization of the valve corresponds to the close of the valve.
The air-filling control device 13 further includes a first flowmeter 138. The first flowmeter 138 is disposed between the second air-filling check valve 137 and the second air inlet 1201 and configured to detect an air-intake flow rate of the massage gasbag 12. The air-exhausting control device 15 further includes a second flowmeter 158. The second flowmeter 158 is disposed between the second air-exhausting check valve 152 and the second air outlet 1203 and configured to detect an air-exhaust flow rate of the massage gasbag 12. In the present embodiment, the air-intake flow rate and the air-exhaust flow rate are controlled by a conjugate square wave control signal produced by the control device 16, a massage frequency of the massage gasbag 12 is decided by a duty ratio of the conjugate square wave control signal, and a massage strength of the massage gasbag 12 is decided by the air-intake flow rate and the air-exhausting flow rate.

Specifically, in a using process of the air eye cover 10, the thin film pressure sensor 18 detects the air pressure in the fixed gasbag 11 and transmits the detected air pressure to the control device 16. The control device 16 judges whether the air pressure arrives at a preset pressure value. When the air pressure is less than the preset pressure value, the control device 16 controls the air pump 132 to switch on, the air release valve 133 to close, the air-filling solenoid valve 134 to open, and the air-filling switch valve 135 to switch to the first output end 1353 to output air thereat, so as to fill air into the fixed gasbag 11. When the air pressure falls into a certain range of the preset pressure value, the fixed gasbag 11 is stopped from being filled with air. Moreover, when the air pressure in the fixed gasbag 11 is detected to be larger than the preset pressure value, the control device 16 controls the air-exhausting solenoid valve 154 to open and controls the air-exhausting switch valve 153 to switch to the first input end 1531 to input air thereat, so that the air in the fixed gasbag 11 can be exhausted appropriately until the air pressure in the fixed gasbag 11 falls into the certain range of the preset pressure value.
It could be understood that the preset pressure value may be predetermined according to requirements of a degree of tightness when the user herself/himself wears the air eye cover. Specifically, the air-filling control device 13 may include an air-filling mechanical switch, and the air-exhausting control device 15 may include an air-exhausting mechanical switch. When the user uses the air eye cover 10 for the first time, the air filling and the air exhaust of the fixed gasbag 11 may be controlled by means of the air-filling mechanical switch and the air-exhausting mechanical switch, and the air-filling and air-exhausting processes are stopped until the air pressure in the fixed gasbag 11 arrives at an optimum pressure perceived by the user. The control device 16 detects a pressure value of the optimum pressure by means of the thin film pressure sensor 18 and records the pressure value of the optimum pressure as the preset pressure value.
The air eye cover 10 further includes an electric heating device 19. The electric heating device 19 includes a heating film 191 and a thin film temperature sensor 193. The heating film 191 is disposed at a side of the massage gasbag 11 facing the human face, electrically connects to the control device 16 and is configured to transform electric energy provided by the control device 16 into thermal energy. The thin film temperature sensor 193 is disposed at a side of the heating film 191 away from the human face, electrically connects to the control device 16 and is configured to detect a temperature of the heating film. It could be understood that a temperature of the electric heating device 19 can be set by the control device 16. It could be understood that in the air eye cover 10 according to embodiments of the present disclosure, various components where the air flows hermetically connect to one another via flexible guiding pipes.
In addition, embodiments of the present disclosure further provide a head-mounted device including a head-mounted display device 20 and an air eye cover 10, as illustrated in
In the air eye cover, the fixed gasbag is provided, and air is filled into the fixed gasbag by the air-filling control device when it is needed to wear the air eye cover, so as to fix the air eye cover and fit the air eye cover with the human face via the fixed gasbag. Moreover, the air in the fixed gasbag may be exhausted by the air-exhausting control device in the using process, so as to adjust the air pressure in the fixed gasbag, thus realizing suitability and fit for faces of different users. Therefore, a great light-blocking effect and a wearing comfort are provided, thus facilitating improvements of the user experience of the head-mounted device. Also, the air eye cover may directly adopt atmosphere as an air source and hence have characteristics of environmental friend and light weight.
