The application provides a can convenient to use just wear portable head mounted display device. In this application, the head-mounted display device can be head-mounted display devices such as VR glasses or AR glasses.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating a head-mounted display apparatus 100 according to some embodiments of the present application. The head mounted display device 100 includes a display screen 110 and a frame 120. The frame 120 includes a support frame 120a supporting the display screen 10, and a temple 120b located at both sides of the display screen 110 and connected to the support frame 120 a. In some embodiments, the head-mounted display device 100 is VR glasses, the display screen 110 is used for displaying images, and the temple 120b is connected to two sides of the display screen 110 and can be hung on the ear of the user, so as to implement wearing of the head-mounted display device 100. In some embodiments, the two earpieces 120b on the two sides of the display screen 110 can be connected by a connection band, so that the head-mounted display device 100 can be worn more stably.

Referring to fig. 2, in some embodiments of the present application, the head-mounted display device 100 further includes a head band 130, and the head band 130 is fixed on the head of the user when the head-mounted display device 100 is worn, so that the head-mounted display device 100 can be fixed more stably and can reduce fatigue caused by wearing for a long time. It is understood that when the head mounted display device 100 is AR glasses, the display screen 110 is actually a lens through which an external scene can be seen.

Referring to fig. 1 and 3 together, in some embodiments of the present application, the head-mounted display apparatus 100 further includes one or more battery compartments 10 and a plurality of batteries 20. The plurality of batteries 20 may have the same or different capacities. Such that the battery compartment 10 comprises a plurality of compartments 11. At least one of the plurality of batteries 20, the battery 20 can be detachably mounted in the battery compartment 10, and each battery 20 mounted in the battery compartment 10 is correspondingly mounted in one compartment 11. In these embodiments, the battery 20 disposed in the battery compartment 10 is connected to functional modules of the head-mounted display apparatus 100, such as a processing module and a display module, so as to provide power for each of the functional modules. In addition, in these embodiments, the number of the batteries 20 disposed in the battery compartment 10 may be less than or equal to the number of the compartments 11 of the battery compartment 10, that is, the number of the compartments 11 of the battery compartment 10 is constant, but one or more batteries 20 may be disposed in the battery compartment 10 according to needs, and the batteries 20 disposed in the battery compartment 10 can both pass through the battery compartment 10 and the head-mounted display device 100, so as to reduce the weight of the head-mounted display device 100 when the head-mounted display device 100 is used for a certain time. For example, when a VR game is played through the head mounted display device 100, the VR game is typically heavy interactive in nature, requiring a large amount of motion, and therefore typically does not take more than half an hour. At this moment, one battery 20 is placed in the battery compartment 10 to satisfy the use, and only one battery 20 is placed in the battery compartment 10, the weight of the head-mounted display device 100 can be greatly reduced, so that the wearing is more portable, and the head-mounted display device is more suitable for being used in VR games. When VR sees the shadow through the head-mounted display device 100, VR sees the shadow then relatively static, and is different according to seeing the shadow content, and the live time is different. Thereby selecting the weight of the battery 20 placed in the battery compartment 10 according to the length of use. For example, when watching a tv show for one hour, a battery 20 may be placed in the battery compartment 10; two batteries 20 may be placed in the battery compartment 10 when viewing a two hour movie.

In the embodiments of the present application, the capacity of each battery may be the same or different. In some embodiments, the capacity of the battery 20 is different, and the battery 20 with different capacity may be selected according to the usage time. For example, when the period of time required to use the head-mounted display device 100 is about half an hour, a battery 20 with a smaller capacity may be selected; when the period of time required to use the head-mounted display device 100 is about one hour, a battery 20 with a larger capacity may 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 the battery 20 with a suitable capacity according to actual needs.

In the present application, by integrating the battery 20 on the head-mounted display device 100, there is no need to connect VR glasses and VR box through a connection line, thereby making the use more convenient. Furthermore, in the present application, the battery compartment 10 of the head-mounted display device 100 includes the battery compartment 10 capable of accommodating a plurality of batteries 20, so that one or more batteries 20 can be detachably placed in the battery compartment 10 according to actual requirements, and the weight of the head-mounted display device 100 can be prevented from being increased by too many batteries 20 when the head-mounted display device 100 is used for a short time, so that the head-mounted display device 100 has a smaller weight and is light to wear when the head-mounted display device 100 is used for a short time.

Moreover, since the battery 20 can be detachably disposed in the battery compartment 10, when the head-mounted display device 100 is used for a long time, the battery 20 can be replaced in the using process, so that the weight of the head-mounted display device 100 is prevented from being increased due to the fact that too many batteries 20 are mounted in the head-mounted display device 100, and the head-mounted display device 100 is convenient to wear.

In some embodiments of the present application, the battery compartment 10 is disposed at a position of the temple 120b of the head-mounted display apparatus 100, so as to fully utilize the space of the head-mounted display apparatus 100.

The sealing cover and the battery compartment 10 may be fixed by various methods such as screw fixation and fastening fixation. In some embodiments, sweat generated from the head and the like can be prevented from entering the battery compartment 10 by positioning the opening of the battery compartment 10 toward the outer surface 122. Moreover, when the head-mounted display device 100 is used, the battery 20 can be conveniently replaced, so that the watching or game process is interrupted, and the user experience is enhanced.

It is understood that the battery compartment 10 may have other configurations. For example, in some embodiments, the temple 120b can include a first portion proximate the head of the user and a second portion removably secured to the first portion and facing away from the surface of the head. The second portion comprises the battery compartment 10 and is secured to the first portion to effect sealing of the battery compartment 10 by the first portion.
