Patent attributes
A head-mounted display device, including a front assembly and a wearable assembly, is provided. The wearable assembly is connected to the front assembly and is adapted for wearing the front assembly to a user's face. The wearable assembly includes a cradle, a coupling mechanism, multiple side headbands, a button, and a position returning member. When the button is pressed relative to the cradle, the button drives the coupling mechanism not to be coupled to the side headbands, so that the side headbands can move freely relative to the cradle to adjust the distance between the cradle and the front assembly. When the button is released relative to the cradle, the position returning member drives the coupling mechanism to be coupled to the side headbands, and tighten the side headbands relative to the cradle through the coupling mechanism.
