The outer casing 20 of the head mounted virtual reality (VR) display device of the present invention will now be described in detail with reference to Figs. 2, 3 and 4. 2 is a perspective view of a housing 20 of a head mounted virtual reality (VR) display device in accordance with a preferred embodiment of the present invention. 3 is a plan view of a fabric sheet assembly 30 used to make the outer casing 20 of the head mounted virtual reality (VR) display device of the present invention. 4 is a cross-sectional view of the fabric sheet assembly 30 taken along line A-A of FIG.

As shown in FIGS. 2 to 4, the outer casing 20 of the head mounted virtual reality (VR) display device of the present invention is a generally elliptical cylindrical casing having a flat first end 21 and a curved shape. a second end 22, wherein the second end 22 of the cylindrical housing is formed with a first recess 23 for receiving a nose portion of the user, a second recess 24 for abutting the user's forehead, and Two light shielding portions 25, 26 between the first recess 23 and the second recess 24.

The outer casing 20 of the head mounted virtual reality (VR) display device of the present invention is made from a fabric sheet assembly 30 as shown in Figs. The fabric sheet assembly 30 comprises a non-woven substrate 301, an adhesive layer 302, which is coated The upper surface and the lower surface of the non-woven substrate 301 are coated; and a surface layer 303 is adhered to the upper, lower and side surfaces of the nonwoven substrate by the adhesive layer 302. The fabric sheet assembly 30 has a first end 32, a second end 33, a flat first edge 34, and a curved second edge 35, wherein the second edge 35 is adjacent the first end 32 and the second end 33 respectively have a first substantially straight portion 36 and a second substantially straight portion 37, a first raised portion 38 and a second raised portion 39, and a first and second raised portion A third substantially straight portion 40 between the portions.

The first end 32 and the second end 33 of the fabric sheet assembly 30 are joined together to form a generally elliptical cylindrical outer casing configuration as shown in FIG. 2, wherein the first substantially straight portion 36 and the first The substantially flat portion 37 constitutes the first recess 23 of the outer casing 20 of the present invention, and the third substantially straight portion 40 constitutes the second recess 24 of the outer casing 20 of the present invention, and the first and second portions The raised portions 38, 39 form the two light blocking portions 25, 26 of the outer casing 20 of the present invention.
