Description

Head-mounted device and strap structure thereof

The present invention relates to a head-mounted device, and particularly relates to a head-mounted device that can quickly adjust the wearing size.

Virtual Reality (VR) technology is a new generation of display technology, which mainly combines computer graphics systems and various display and control devices to produce virtual three-dimensional images. Virtual three-dimensional images are mainly realized by VR glasses, and VR glasses are usually combined with a strap to form a head-mounted display, which is convenient for users to wear.

Generally speaking, the strap of a head-mounted display needs an adjustable length of about 20 cm to adapt to the head size of different users. After the user wears the head-mounted display, gradually tighten the strap until it meets the size of the user's head shape. In addition, when the user wants to take off the head-mounted display, the strap needs to be unfastened. If the user needs to fine-tune the tightness and wearing position of the strap, this will result in a lengthy adjustment time. Therefore, how to improve the adjustment efficiency of the head-mounted display is currently an important development goal.

The invention provides a head-wearing device and a strap structure thereof, which can quickly adjust the wearing size of the strap to improve the adjustment efficiency.

The switch assembly is configured in the adjustment assembly to switch the adjustment assembly into a coupled or uncoupled state, wherein the adjustment assembly is coupled to the first strap and the second strap in the coupled state to drive the first strap and the second strap to move relative to each other , And the adjusting component is unhooked from the first strap and the second strap in the unhooked state, so that the first strap and the second strap can move freely relative to the adjusting component.

The strap structure of the present invention includes a first strap, a second strap, an adjusting component and a switching component. A first part of the first strap and a second part of the second strap overlap each other. The adjusting component is suitable for coupling the first strap and the second strap, and is used to adjust the degree of overlap between the first part and the second part. The switch assembly is configured in the adjustment assembly to switch the adjustment assembly into a coupled or uncoupled state, wherein the adjustment assembly is coupled to the first strap and the second strap in the coupled state to drive the first strap to face the second strap Move, and the adjusting component is unhooked from the first strap and the second strap in the unhooked state, so that the first strap and the second strap can move freely relative to the adjusting component.

Based on the above, the headwear device of the present invention gradually adjusts the overlap between the first strap and the second strap through the adjustment component, and then changes the wearing space to match the size of the user's head. At this time, the adjustment component is in a coupled state. In addition, the adjustment component can be switched from the coupled state to the uncoupled state by switching the component. In the unhooked state, the adjusting component is unhooked from the first strap and the second strap, so that the first strap and the second strap can move freely relative to the adjusting component, allowing the user to quickly adjust the size of the wearing space to achieve Improve adjustment efficiency.
