[0002] With the development of technology, head-mounted display devices are increasingly used in daily life. In order to meet different usage needs, head-mounted display devices are becoming more and more functional, which leads to an increase in the amount of electricity they consume.

[0003] Currently, the batteries of many head-mounted display devices are located inside the back of the headband. Due to the limited structure of the back of the headband, the battery capacity is limited, resulting in a relatively short usage time for head-mounted display devices. The head-mounted display device must be removed from the user's head to charge, making it impossible to use the head-mounted display device continuously. Summary of the Invention
