Abstract

A head-mounted display apparatus may include: a main frame, one surface of which faces a user'"'"'s face; and a support part coupled to at least part of the main frame to fix the main frame to the user'"'"'s face, wherein the main frame has a cavity structure such that an electronic device is mounted on an opposite surface thereof and includes a position adjustment part for adjusting the position of an electronic device, and a structure for preventing the electronic device from being tilted during the position adjustment is included in the interior of the main frame.

Claims

1. A head-mounted display apparatus comprising:

a main frame, one surface of which is adapted to face a user'"'"'s face; and

a support part coupled to at least part of the main frame to fix the main frame to the user'"'"'s face,

wherein the main frame comprises a cavity structure such that an electronic device is mounted on an opposite surface thereof and a position adjustment part for adjusting the position of the electronic device, and wherein the main frame includes a structure on an interior surface thereof that is configured to inhibit the electronic device from being tilted during position adjustment.

2. The head-mounted display apparatus of claim 1, wherein the one surface of the main frame has a curved-surface structure of a facial shape such that the user is able to wear the head-mounted display apparatus, and the opposite surface thereof has a structure in which the electronic device is mounted thereon.

3. The head-mounted display apparatus of claim 1, wherein the main frame comprises:

a front case that has a space or structure therein where the electronic device is coupled, and moves together with the electronic device;

a rear case, one surface of which has a curved-surface structure of a facial shape such that the user is able to wear the head-mounted display apparatus; and

a lens fixing part disposed between the front case and the rear case to support a lens and a structure for preventing tilting of the electronic device.

4. The head-mounted display apparatus of claim 3, wherein the main frame further comprises a cover coupled to the front case to support the electronic device.

5. The head-mounted display apparatus of claim 3, wherein the structure for preventing the tilting of the electronic device comprises one or more lens moving rails and one or more fixing members, and the one or more fixing members are provided integrally with or separately from the lens fixing part.

6. The head-mounted display apparatus of claim 5, wherein the structure for preventing the tilting of the electronic device further comprises one or more resilient members.

7. The head-mounted display apparatus of claim 6, wherein the resilient members are at least one of coil springs, plate springs, hydraulic springs, rubbers, and sponges.

8. The head-mounted display apparatus of claim 6, wherein the one or more fixing members include hooks that support the one or more resilient members, wherein the one or more fixing members include recesses that support the one or more lens moving rails.

9. The head-mounted display apparatus of claim 8, wherein the one or more lens moving rails are located in an interior of respective ones of the one or more resilient members.

10. The head-mounted display apparatus of claim 3, wherein the front case comprises one or more coupling cylinders coupled with the one or more lens moving rails, and wherein the one or more lens moving rails are located in the interior of the one or more coupling cylinders, and the one or more resilient members are located on an exterior of the one or more coupling cylinders.

11. The head-mounted display apparatus of claim 10, wherein bushes are located in an interior of the one or more coupling cylinders.

12. The head-mounted display apparatus of claim 8, wherein the one or more lens moving rails have a thread formed on one end thereof and are fixedly coupled to one or more lens moving rail fixing parts located in an interior of the rear case.

13. The head-mounted display apparatus of claim 5, wherein the one or more resilient members, the one or more lens moving rails, and the one or more fixing parts are disposed at the same positions on four corners of the front case, the lens fixing part, and the rear case, and the one or more lens moving rails pass through the lens fixing part and are supported by the rear case.

14. The head-mounted display apparatus of claim 1, further comprising:

a moving gear located in an interior of the main frame to adjust the position of the electronic device using a force transmitted from the position adjustment part.

15. The head-mounted display apparatus of claim 1, further comprising:

a touch panel on at least one side of the main frame, wherein the touch panel displays a graphical user interface (GUI) capable of manipulating a function of the electronic device and receives an input signal from the user,

wherein the main frame further comprises a nose recess on the one surface thereof, and wherein the support part is one of a goggle band, an eyeglass temple, a helmet, and a strap.

16. The head-mounted display apparatus of claim 1, wherein the main frame further comprises:

a memory;

a communication module;

a sensor module configured to measure at least one of a distance and a depth between an electronic device and the head-mounted display apparatus or detecting an operation of the position adjustment part;

an input device for receiving a user input signal; and

a controller configured to;

display a graphical user interface (GUI) capable of controlling a function of the electronic device on a user input module, and controls the communication module to establish a communication connection when the electronic device is coupled and to transmit the user input signal or a signal for controlling the electronic device according to the user input signal to the electronic device.

17. The head-mounted display apparatus of claim 16, wherein the position adjustment part comprises a pattern allowing the sensor module to detect an operation of the position adjustment part.

18. The head-mounted display apparatus of claim 17, wherein the controller is configured to detect the operation of the position adjustment part through the sensor module and to display a user interface for identifying a tilt on the electronic device.

19. The head-mounted display apparatus of claim 18, wherein the user interface for identifying a tilt provides a blurred or defocused image when the electronic device is tilted with respect to the head-mounted display apparatus and a focused or clear image when the electronic device is not tilted with respect to the head-mounted display apparatus.

20. The head-mounted display apparatus of claim 17, wherein the controller is configured to:

detect the operation of the position adjustment part through the sensor module;

activate an operation of the sensor module, to measure a distance between the electronic device and the head-mounted display apparatus through the sensor module;

display the measured distance through the electronic device; and

stop displaying the measured distance on the electronic device when the measured distance is in an error range.
