The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

The present application provides a head-mounted display device that is convenient to use and light to wear. In this application, the head-mounted display device may be a head-mounted display device such as VR glasses or AR glasses.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of a head-mounted display device 100 according to some embodiments of the application. The head-mounted display device 100 includes a display screen 110 and a frame 120. Wherein, the spectacle frame 120 includes a support frame 120a supporting the display screen 10 and spectacle legs 120b located on both sides of the display screen 110 and connected to the support frame 120a. In some embodiments, the head-mounted display device 100 is VR glasses, the display screen 110 is used for screen display, and the temples 120b are connected to both sides of the display screen 110 and can be hung on the user's ears. In order to realize the wearing of the head-mounted display device 100. In some embodiments, the two temples 120b located on both sides of the display screen 110 can be connected by connecting straps, so that the head-mounted display device 100 can be worn more stably.

Please refer to FIG. 2. In some embodiments of the present application, the head-mounted display device 100 further includes a headband 130. When the head-mounted display device 100 is worn, the headband 130 is fixed on the head of the user. Therefore, the head-mounted display device 100 can be fixed and more stable, and the fatigue caused by long-term wear can be reduced. It is understandable that when the head-mounted display device 100 is AR glasses, the display screen 110 is actually a lens through which the outside scene can be seen.

Please refer to FIGS. 1 and 3 together. In some embodiments of the present application, the head-mounted display device 100 further includes one or more battery compartments 10 and a plurality of batteries 20. Wherein, the capacity of the plurality of batteries 20 may be the same or different. Therefore, the battery compartment 10 includes a plurality of positions 11. At least one battery 20 of the plurality of batteries 20 can be detachably installed in the battery compartment 10, and each battery 20 installed in the battery compartment 10 is correspondingly installed in a position 11. In these embodiments, the battery 20 arranged in the battery compartment 10 is connected to the processing module, display module and other functional modules of the head-mounted display device 100 to provide power to each of the functional modules. Moreover, in these embodiments, the number of batteries 20 provided in the battery compartment 10 may be less than or equal to the number of the positions 11 of the battery compartment 10, that is, the number of the positions 11 of the battery compartment 10 is certain, but One or more batteries 20 can be provided in the battery compartment 10 as required, and the batteries 20 provided in the battery compartment 10 can pass through the battery compartment 10 and the head-mounted display device 100, thereby reducing the use of the headset for a certain period of time. The weight of the head-mounted display device 100 when the display device 100 is mounted. For example, when a VR game is played through the head-mounted display device 100, the VR game is usually interactive and requires a lot of exercise, so it usually takes less than half an hour. At this time, one battery 20 in the battery compartment 10 is sufficient for use, and only one battery 20 in the battery compartment 10 can greatly reduce the weight of the head-mounted display device 100, making it easier to wear Lightweight, more suitable for use in VR games. When performing VR movie watching through the head-mounted display device 100, the VR movie watching is relatively static, and the usage time is different according to different movie contents. Therefore, the weight of the battery 20 placed in the battery compartment 10 is selected according to the length of use. For example, when watching a one-hour TV show, one battery 20 can be placed in the battery compartment 10; when watching a two-hour movie, two batteries 20 can be placed in the battery compartment 10.

In each embodiment of the present application, the capacity of each battery may be the same or different. In some embodiments, the capacities of the batteries 20 are different. Depending on the length of use, batteries 20 with different capacities may also be used. For example, when the head-mounted display device 100 needs to be used for about half an hour, a battery 20 with a smaller capacity can be selected; when the head-mounted display device 100 needs to be used for about one hour, A battery 20 with a larger capacity can be selected. In some embodiments, a label may be provided on the battery 20, and the length of time that the battery 20 can be used is marked on the label, so that the user can select a battery 20 with a suitable capacity according to actual needs.
