Virtual Reality is a technology that creates a virtual world in a similar way through a computer or video display device, and manipulates and experiences the virtual world according to the movement of the body. These attempts have been widely used for various simulator devices, robot remote control and games. In recent years, a variety of virtual reality experience applications have been provided along with the development of smart phones and tablet PCs, and technologies and devices capable of experiencing virtual reality through a separate virtual reality HMD have been developed.

  However, in the conventional virtual reality HMD, a space for accepting a smart phone must be separately formed in the virtual reality HMD due to the feature of inserting and using a smart phone. The disadvantage of this feature is that the volume of the virtual reality HMD becomes large, have. In addition, while the virtual reality application is running through the smartphone, the fever of the smartphone gradually becomes worse and the performance of the smartphone may be deteriorated.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a foldable virtual reality HMD having a cooling fan mounted thereon, The present invention provides a foldable virtual reality HMD equipped with a cooling fan which is inserted into a large-sized barrel b to reduce the volume.

Another object of the present invention is to provide a foldable virtual reality HMD equipped with a cooling fan by forming a cooling fan inside a front cover in order to overcome the heat generated by a smart phone during the operation of a virtual reality application .

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a virtual reality HMD having a cooling fan mounted thereon, the virtual reality HMD including: a smartphone module including a smartphone accessory;

A smartphone holder 30 for holding the smartphone together with the smartphone film 32; And

A front cover 10 formed on the front part and protecting the smartphone and the cooling fan 20; And

A cooling fan 20 mounted inside the front cover 10;

And a barrel a (40);

And a barrel b (42) of a larger size into which the barrel a (40) is inserted;

And an eyepiece membrane (60) for binding between the lens barrel (42) and the lens body (52);

And a pair of fisheye lenses (50);

And a lens body 52 coupled with the fish-eye lens 50;

And an eyepiece part (62) which is joined to the lens body (52)

.

As described above, according to the folding virtual reality HMD equipped with the cooling fan according to the present invention, the barrel of a conventional virtual reality HMD having a bulky volume can be divided into different sizes and a small-sized barrel "a" So that it is possible to reduce the volume and improve the portability.

In addition, according to the folding virtual reality HMD equipped with the cooling fan according to the present invention, a cooling fan is formed in order to solve the high heating phenomenon of the smartphone displayed during driving the conventional virtual reality application, It is possible to prevent the deterioration of the performance of the smartphone.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art. To fully disclose the scope of the invention to a person skilled in the art, and the invention is only defined by the scope of the claims.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains.

First, a folding virtual reality HMD equipped with a cooling fan according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6. FIG.

1 is a perspective view of a folding virtual reality HMD equipped with a cooling fan according to an embodiment of the present invention,
