As shown in fig. 1, the head-mounted display device includes a display screen 110 and a headband component 120, the headband component 120 is made of a ring-shaped hard material, for example, the headband component 120 may be made of a hard material such as plastic or metal, and the headband component 120 further includes a wheel and a rack, and the wheel and the rack are driven by the wheel located at the hindbrain position, so as to adjust the size.

Based on the head-mounted display device shown in fig. 1, because the large-sized hard material is adopted, the head-mounted display device is bulky, difficult to store and difficult to carry. In addition, the head-mounted display device shown in fig. 1 has a complicated structure, a large number of parts, a heavy weight, and a high cost. The structures such as the gear, the rotating wheel and the like for adjustment are positioned behind the brain and have the structural thickness not less than 30mm, so that the head-wearing display equipment is easy to be clung to the head when a user lies down or leans against the head, and the head-wearing display equipment cannot be used for a long time.

Fig. 2 shows a head-mounted display device in the prior art. As shown in fig. 2, the head-mounted display device includes a display screen 210 and a headband part 220, the headband part 220 is formed by weaving cloth and elastic tape, is hung on the display screen 210, and is fixed by a hook and loop fastener, and the length and size of the head-mounted display device can be adjusted by adjusting the sticking position.

Based on the head-mounted display device shown in fig. 2, since the position of the head band part 220 is generally adjusted by 2-3 sections of velcro tapes when using the velcro tapes, the operation of adjusting the length is difficult. In addition, since each of the sections of the hook and loop fasteners needs to be tightened on the head, the overall comfort is poor, for example, the positions of the ears interfere with the headband component 220. Soft headbands are generally not securely locked and comfortably supported.

In view of this, embodiments of the present application provide an adjustable headband apparatus that may be easily adjusted and stowable by employing elastic members such as elastic bands and a rotating wheel assembly member such as a wire winding wheel.
