[0002] VR glasses are a kind of virtual reality device that allows users to have an immersive experience and immerse themselves in various virtual scenes, such as games, movies, education and other fields. Currently, VR glasses mostly use mobile phones as display devices and provide images by playing specific VR content. When in use, the mobile phone is placed inside the shell of the VR glasses, and the lenses in the glasses refract and magnify the image on the mobile phone screen, allowing the user's eyes to see three-dimensional images with a sense of depth.

[0003] However, the shell of current VR glasses is relatively closed, air flow is not smooth, and heat exchange efficiency is low, which makes it difficult for the heat of the mobile phone to dissipate after continuous use, and it is easy to get hot and stuck, which reduces the user experience. In addition, the heat of the mobile phone accumulates inside the VR glasses and is easily transferred to the part of the VR glasses that contacts the user's face, which will increase the feeling of stuffiness when wearing and reduce the user experience. Therefore, those skilled in the art provide a structure for enhancing the heat dissipation of VR glasses and VR glasses to solve the problems raised in the above background technology.

[0036] The heat dissipation component 7 includes a heat conductive sheet 71 and two groups of heat dissipation sheets 73. A plurality of heat conductive pipes 72 are fixedly connected between the heat conductive sheet 71 and the two groups of heat dissipation sheets 73.

The heat dissipation component 7 is in direct contact with the back cover of the mobile phone, which not only enhances the heat dissipation, but also supports the mobile phone and improves the stability of the mobile phone. At the same time, after the front cover 2 is opened, the heat dissipation component 7 will also be directly separated from the mobile phone without affecting the placement and removal of the mobile phone. The heat conductive sheet 71 and the heat dissipation sheet 73 are made of aluminum, and the heat conductive pipe 72 is made of copper, which has good thermal conductivity and can efficiently dissipate the heat on the mobile phone. The heat dissipation sheet 73 has a large surface area and can quickly dissipate heat when the airflow passes through. In addition, the two groups of heat dissipation sheets 73 are extended toward the air outlet 34, which can increase the heat dissipation area and improve the heat dissipation effect.

The air regulating valve 43 can adjust the amount of airflow supplied to the air outlet buffer pad 41. When adjusting, the rotating roller 431 drives the internal adjusting valve plate 432 to rotate, so that the gap between the adjusting valve plate 432 and the fixed valve plate 433 changes, thereby changing the airflow size.

[0043] The upper portion of the connecting base 31 is located inside the shell 1, and the lower portion of the connecting base 31 is located at the outer end of the shell 1.
