BEST MODE FOR CARRYING OUT THE INVENTION

[0011] The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] Referring to FIG. 1 to FIG. 4, the head mounted virtual reality device of the embodiment includes a device body 10 and a device body.

10 includes a housing 11 and a housing inner cavity 12. The device body 10 is provided with a heat dissipation structure. The heat dissipation structure includes a heat sink 13 disposed in the housing interior 12, a heat dissipation fan 14 disposed in the housing interior 12, and a housing disposed in the housing. The heat dissipation hole 15 on the body 11.

[0013] By providing a heat dissipation structure, the heat source is conducted by the heat sink 13 in the housing inner cavity 12, and the heat convection is accelerated by the heat dissipation fan 14, so that the hot air is discharged from the heat dissipation hole 15, thereby improving the heat dissipation effect of the head mounted virtual reality device. . In order to improve the heat dissipation effect and to minimize the weight of the head-mounted virtual reality device as much as possible, so as not to affect the wearing comfort, the heat sink 13 is preferably an aluminum alloy heat sink in this embodiment.

[0014] Further, the heat dissipation fan 14 faces the heat sink 13, as shown in FIG. 4, to further accelerate the heat convection.

[0015] Generally, for ease of assembly, the housing 11 includes an upper cover 111, a lower housing 112, and a housing body 113 between the upper cover 11 1 and the lower housing 112. The upper cover 111 is located at the housing main body 113. On the upper side, the lower casing 112 is located on the lower side of the casing main body 113, and the upper cover 111 has a downwardly inclined side surface 1111. The heat dissipation hole 15 is disposed on the inclined side surface 1111, so that the heat dissipation hole 15 can be concealed on the casing 11. In order to reduce the adverse effect on the appearance of the product, and because the heat gas density is small, the upward flow, the heat dissipation hole 15 is located on the upper cover 111, which is favorable for the flow of the hot air to be dissipated.

[0016] In order to further improve the appearance effect of the head-mounted virtual reality device and improve the market competitiveness, as shown in FIG. 1 and FIG. 3, the connecting seam of the upper cover 111 and the housing main body 113 is provided with a decorative strip 16 and a decorative strip. The 16 has a heat dissipation groove 161 facing the heat dissipation hole 15. The heat dissipation groove 16 of the decorative strip 16 can evade the heat dissipation holes 15 on the upper cover 111 to avoid affecting the release of hot air.

[0017] In order to enhance the convection of the airflow and accelerate the dissipation of the hot air, the lower casing 112 is provided with a communication with the casing inner cavity 12. The air inlet hole 1121 can introduce an external natural wind from the air inlet hole 1121 to form a convection with the hot air in the casing inner cavity 12 to accelerate the release of the hot air.

[0018] Further, the front side edge of the lower case 112 has a recessed portion 1122, and the air intake hole 1121 is located at the recessed portion 112.

On the second side, the air intake hole 1121 is not easily observed from the surface of the lower case 112, and the concealed arrangement of the air intake hole 1121 is realized to reduce the adverse effect on the appearance of the product.

Further, the outline of the lower case 112 is preferably a downward convex arc shape, and the arc shape of the lower case 112 helps to guide the airflow into the air inlet hole 1121 to enhance the convection effect.

[0020] The head-mounted virtual reality device of the embodiment provides a heat dissipation structure, conducts a heat source by means of an internal heat sink, accelerates heat convection with a heat dissipation fan, and discharges hot air from the heat dissipation hole, thereby improving the head-mounted virtual reality device. Cooling effect and prolonged service life.
