Description

Head-mounted display device Technical Field The present disclosure relates to wearable electronic devices, and particularly to a head-mounted display device. Background Generally, a head-mounted display device includes a control device and a head-mounted display. The control device is arranged in the head-mounted display. The control device may drive or control the head mounted display to provide the image. The device battery in the control device is used for providing electric energy for the control device. It should be noted that the volume or weight of the battery itself in the control device is limited based on the wearing requirements. The length of time for powering the battery in the control device is also limited. Therefore, the length of time for which the wearable display device is used may also be limited. Disclosure of Invention The invention provides a head-mounted display device capable of prolonging the service time of the head-mounted display device. In an embodiment of the invention, the head-mounted display device comprises a head-mounted display, a control device and an expansion battery. The control device includes a device battery and a controller. The controller is coupled to the device battery and the head-mounted display. The controller controls the operation of the head mounted display. The expansion battery is detachably assembled with the control device. After the expansion battery and the control device are assembled, the expansion battery supplies power to the control device and charges the device battery. Based on the above, after the extended battery and the control device are assembled, the extended battery can supply power to at least one of the controller and the device battery. Therefore, the use time length of the head-mounted display device can be prolonged.
