Abstract

The present invention provides a head mounted display comprising: a rear case for accommodating a lens part; a front case, which is coupled to the rear case, forms an exterior, and includes an open part; a fixing part, which performs a particular function, has one end mounted on the rear case so as to prevent the separation of the rear case from the front case, and passes through the open part so as to be exposed to the outside; and a controller, wherein the controller generates a control command through the fixing part or controls the fixing part such that data is outputted, and the front case is made of polypropylene (PP) or polycarbonate (PC).

First claim

The invention claimed is:

1. A head mounted display (HMD) comprising:
a rear case for accommodating a lens unit;
a front case coupled to the rear case to form an outer appearance and provided with an opening part; and
a key unit fixed to the rear case and configured to be pressed by an external force to generate a control command,
wherein the key unit includes a key bracket fixed to the rear case, and a pressing portion mounted on the key bracket in a pressable manner and penetrating the opening part,
wherein the front case is made of polypropylene (PP) or polycarbonate (PC),
wherein the front case includes a support part and a cover,
wherein the support part includes a plurality of ribs forming a plurality of holes,
wherein the plurality of ribs form a front portion and a side portion of the support part, and
wherein the front portion and the side portion are sewn together, preventing wrinkles forming on an outer surface of the cover of the front case.

2. The head mounted display of claim 1 , wherein the key bracket includes a side wall portion fitted to the opening part and a locking portion protruding from the side wall portion and supported by the front case.

3. The head mounted display of claim 1 , wherein the opening part includes a pair of holes formed to face each other, and
wherein the head mounted display further includes a pair of earphone units disposed in the pair of holes, respectively, and outputting auditory data.

4. The head mounted display of claim 3 , wherein each of the pair of earphone units includes:
a control module mounted on the rear case;
a housing fixed to the control module and formed to be fitted into the pair of holes; and
an earphone module electrically connected to the control module and disposed on the housing in an attachable and detachable manner.

5. The head mounted display of claim 1 , further comprising a band connected to the rear case,
wherein the rear case includes a fixing slit to which both ends of the band are fixed.

6. The head mounted display of claim 1 , wherein the lens unit is mounted on one surface of the rear case, and
wherein the front case is provided with a reinforcement portion protruding from the one surface so as to support at least a part of edges of the front case.

7. The head mounted display of claim 1 , further comprising an adhesive guide portion formed between the rear case and the front case,
wherein the adhesive guide portion protrudes toward the front case and includes at least one adhesive surface adhered to the front case, and
wherein the adhesive guide portion is formed integrally with the rear case.

8. The head mounted display of claim 1 , wherein the plurality of holes include hexagonal-shaped holes.

9. The head mounted display of claim 1 , wherein the plurality of holes include triangular-shaped holes.

10. The head mounted display of claim 1 , wherein the support part is made of polycarbonate (PC).

11. The head mounted display of claim 10 , wherein the cover is made of a fabric.

12. The head mounted display of claim 1 , wherein the cover includes a first cover portion configured to cover the front portion and a second cover portion configured to cover the side portion.

13. The head mounted display of claim 1 , wherein the cover is covered over an outer surface of the support part.

14. The head mounted display of claim 13 , wherein the cover is configured to block light entering through the plurality of holes.

15. The head mounted display of claim 1 , wherein the rear case is placed on an inner space defined by the support part.

16. The head mounted display of claim 1 , wherein the support part made up of the plurality of ribs forms a keyhole through which at least a part of the key unit passes.
