The present invention provides a head mounted display device, in some embodiments, referring to fig. 1-10, comprising a main body 1, a control assembly (not shown), and a head mounted assembly 2 coupled to the main body 1.

The main body 1 includes a screen and a detection sensor. One side of the body 1 is fitted to the face of the user, facing the head set 2. The detection sensor is used to detect external information of the main body 1. Taking the detection sensor as the distance sensor 11 as an example, the detection direction of the distance sensor 11 faces the head-mounted assembly 2 for detecting the distance between the main body 1 and the external object. Based on the detected information, the distance sensor 11 emits a first signal. The distance sensor 11 is electrically connected to a control assembly, which receives the first signal.

The control component can be a control main board in the head-mounted display equipment in the prior art, and the like, and can process electronic signals and send control instructions; in various embodiments, the core processor may also be a host computer connected to the head-mounted display device, which is not limited in this disclosure, and may be capable of processing signals and transmitting instructions.

The headgear assembly 2 includes a wear portion 3 and a main strap 4. The main band 4 connects the main body 1 and the wearing part 3. The wearing part 3 is opposite to the main body 1 when the head-mounted display device is in use, the wearing part 3 is positioned on the back surface of the head of a user when the head-mounted display device is in use, and the wearing part is clamped with the main body 1 to fix the head-mounted display device on the head of the user.

The wearing part 3 is rotatably connected with the main body 1 through a main belt 4. At least one rotation joint is provided between the wearing part 3 and the main body 1. It is possible that the main belt 4 is rotatably connected to the main body 1, or/and that the main belt 4 is rotatably connected to the wearing part 3, or/and that the main belt 4 includes at least a front belt 41 and a rear belt 42 rotatably connected, which is not limited by the present disclosure. Referring to fig. 3, there may be a main body 1, a front belt 41, a rear belt 42, and a wearing part 3 which are rotatably connected in order; in some other embodiments, the main belt 4 may include at least a front belt 41 and a rear belt 42 rotatably connected, and the connection between the main belt 4 and the main body 1 or/and between the main belt 4 and the wearing part 3 may be elastically bendable and foldable, so long as there is at least one rotation connection.

At least one of the rotational joints is a switch section provided with a switch sensor 21. The front belt 41 and the rear belt 42 are exemplified as the switch portion rotatably connected. Referring to fig. 1, the relative position between the front belt 41 and the rear belt 42 can be rotated to a relatively open position, forming a wearing state; referring to fig. 5, the folding device can be rotated to the folded position to form the storage state. By the front and rear bands 41 and 42 being unfolded or folded, the wearing part 3 can be moved away from and toward the main body 1 so that the head-mounted display device has different spatial volume forms. When in use, the front belt 41 and the rear belt 42 are opened to enable the wearing part 3 to be far away from the main body, and the head-mounted display device can be worn and used by a user; when not in use, the front belt 41 and the rear belt 42 are folded, so that the wearing part 3 is close to the main body 1, and the space volume of the head-mounted display device is reduced, thereby being convenient for storage and carrying.

In some other embodiments, the main belt 4 may further comprise a plurality of parts connected in turn in rotation, so as to enable the wearing part 3 to be far from and near to the main body 1; or the wearing part 3 can be brought to a specific position, i.e. the present disclosure is not limited to the number of rotational connections on the main belt 4.

The rotational connection of the front belt 41 and the rear belt 42 is provided with a switch sensor 21. The switch sensor 21 is electrically connected to the control assembly. When the front belt 41 and the rear belt 42 are in the wearing state, the switch sensor 21 sends out a second signal, and the control assembly receives the second signal.

The control assembly is also electrically connected to the screen. And when the first signal received by the control component reaches the wake-up condition of the screen, the second signal is also received, and the screen is waken up. When the first signal cannot reach the wake-up condition of the screen or/and the second signal cannot be received, the screen is extinguished. Taking the detection sensor as the distance sensor 11 as an example, the wake-up condition of the first signal may include that a distance between the main body 1 and an external object outside the main body 1 is smaller than a preset threshold value.

The method and the device can automatically control the screen to be awakened and light when the user wears the head-mounted display device, and manual control is not needed.

The head-mounted display device disclosed by the disclosure can control the volume of the head-mounted display device by rotating and connecting the wearing part 3 and the main body 1, and is opened when in use and is convenient to store and carry by folding when not in use.

The head-mounted display device can prevent the first signal from reaching the awakening condition of the screen when being stored or the main belt 4 is folded to the storage state, so that the screen is awakened to waste electric energy. Only when the switch part is opened to the wearing state, the switch sensor 21 sends out a second signal, and when the user possibly uses the head-mounted display device, the first signal reaches the awakening condition of the screen, so that the screen can be awakened, and the probability of awakening the screen by misoperation is reduced. The working time of the screen can be reduced, unnecessary power consumption is reduced, and the service life of the head-mounted display device is prolonged. The screen is prevented from being awakened by folding the wearing part 3 and the main body 1 when not in use and is convenient to store and carry.

In some embodiments, the state of wear of the switch portion may be a fixed relative position; or may have a range of relative positions, for example, capable of being rotated 5 ° clockwise or counterclockwise in the relative position shown in fig. 2, to accommodate different user head sizes.

In some embodiments, the main belt 4 is further provided with a limiting mechanism, so that the switch part is limited to rotate only in the wearing state and the storage state, and the stability of the disclosed head-mounted display device when worn is ensured. Further, the limiting assembly may be provided in a conventional manner in the art, such as a limiting baffle, and the disclosure is not limited thereto.

In some embodiments, referring to fig. 1 and 5, the front surface of the head-wearing part 3 can be opposite to and away from the side of the main body 1 that is fitted to the face of the user when the switch part is in the wearing state. When the switch unit is in the wearing state, the back surface of the head-wearing unit 3 can be placed in opposition to and close to the side of the main body 1 to which the user's face is attached. Further, the main belt 1 has a cavity for accommodating the face on the side where the face of the user is attached, and when not in use, the back surface of the head-wearing part 3 can be as close to or extend into the cavity as possible, and referring to fig. 4, the back surface can extend to contact with the attaching surface 15 of the main belt 1, thereby reducing the volume of the head-wearing display device when in storage as much as possible and increasing portability. In some other embodiments, the head 3 may also be proximate to other sides of the body, as this disclosure is not limiting.

In some embodiments, the switch sensor 21 comprises a micro switch or a tact switch. Taking the front belt 41 and the rear belt 42 which are rotatably connected by the switch portion as an example, referring to fig. 1 and 5, when the front belt 41 and the rear belt 42 rotate, the relative position therebetween changes, and the micro switch or the tact switch can be physically turned on or off by the positional relationship therebetween, so that the result of determining the relative position therebetween is more accurate. Further, when the front belt 41 and the rear belt 42 are in the wearing state, the micro switch or the tact switch is turned off to send a second signal, and when the front belt 41 and the rear belt 42 are in the storage state, the micro switch or the tact switch is turned on to close the circuit and the second signal is not sent; the micro switch is turned on or the touch switch is turned on to send a second signal when the portable electronic device is in a wearing state, an extra circuit is not needed, the structure is simpler, and electricity is saved when the portable electronic device is stored. Of course, the present disclosure does not exclude the manner of closing in the wearing state described above.

Further, the switch portion has a proximal end and a distal end rotatably coupled thereto. Referring to fig. 2 to 4, one end of the front belt 41 is a proximal end, one end of the rear belt 42 is a distal end, for example, the switch sensor 21 is provided on the front belt 41, and when the front belt 41 and the rear belt 42 are in a wearing state, the switch sensor 21 is abutted and opened by the rear belt 42. Those skilled in the art will appreciate that the front and rear straps 41, 42, proximal and distal ends are merely relative relationships and are not absolute positions in a head mounted display device.

Further, referring to fig. 2-4, one end (proximal end) of the front belt 41 and one end (distal end) of the rear belt 42 are provided with mutually mating concave portions 43 and convex portions 44, respectively. The projections 44 extend into the recesses 43 and are connected by a rotational shaft 45 to form a rotational connection. The switch sensor 21 is disposed on the bottom surface of the concave portion 43 opposite to the convex portion 44. When the switch part is in the storage state, the bottom surface of the concave part 43 can be protected by the side wall with higher periphery, so that the screen is prevented from being started by misoperation caused by triggering by other objects other than the convex part 44.

In some embodiments, referring to fig. 7 and 8, the detection sensor includes at least one of a distance sensor 11 or a pressure sensor 12. Further, referring to fig. 9 and 10, at least one of the temperature sensor 13 or the carbon dioxide concentration sensor 14 may be further included. One or more first signals are also corresponding to the first signals, so that the probability of misoperation is reduced.

Further, referring to fig. 7, the detection end of the distance sensor 11 faces the head mount assembly 2, and detects the distance to an object outside the main body 1 between the main body 1 and the head mount assembly 2. The wake-up condition may include that a distance between the main body 1 and an external object outside the main body 1 detected by the distance sensor 11 is less than a preset threshold value.

Further, the distance sensor 11 includes a sensor capable of measuring a distance, such as an infrared distance sensor or an ultrasonic distance sensor.

Further, referring to fig. 8, the pressure sensor 12 is provided on the abutment surface 15 of the main body 1 for making contact with the face of the user, and detects the pressure on the abutment surface 15. The wake-up condition may include the pressure on the abutment surface 15 detected by the pressure sensor 12 being greater than a preset threshold.

Further, referring to fig. 9, the temperature sensor 13 is provided on the contact surface 15 of the main body 1 for contact with the face of the user, and detects the temperature on the contact surface 15. The wake-up condition may include the temperature on the faying surface 15 detected by the temperature sensor 13 being greater than a preset threshold.

Further, referring to fig. 10, the bottom of the main body has a relief portion 16 that is configured to clear the nose of the user. The carbon dioxide concentration sensor 14 is disposed on the bottom adjacent to the avoidance portion 16. The carbon dioxide concentration around the avoidance portion 16 is detected. The wake-up condition may include the carbon dioxide concentration around the let-down portion 16 detected by the carbon dioxide concentration sensor 14 being greater than a preset threshold.

In some embodiments, the main belt 4 may be made of plastic, rubber, or the like, or a composite of materials.

In some embodiments, referring to fig. 1, the cross section of the main band 4 is arc-shaped, and two ends of the arc are respectively connected to the top of the main body 1 and the wearing part 3, and when the wearing part is worn, the main band 4 is above the head of a user and can be matched with the shape of the head.
