Description

Head mounted display

The invention relates to a head-mounted display, and in particular to a head-mounted display that can quickly adjust the wearing size.

Virtual reality (Virtual Reality, VR) technology belongs to 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 usually combine a strap to form a head-mounted display (head-mounted display), which is convenient for users to wear.

Generally speaking, the headband display strap requires an adjustable length of about twenty centimeters to suit the head size of different users. When the user wears the head-mounted display, the band is gradually tightened until it matches the size of the user's head. In addition, when the user wants to take off the head-mounted display, they need to untie the strap. If the user needs to fine-tune the tightness of the strap and the wearing position, 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-mounted display, which can quickly adjust the wearing size of the strap to improve the adjustment efficiency.

The head-mounted display of the present invention includes a wearing part, a display body, a first strap, a second strap, an adjustment component, and a switching component.

The adjusting component is adapted to couple the first strap and the second strap to adjust the overlapping degree of the first part and the second part, thereby changing the wearing space. The switching component is configured on the adjusting component to switch the adjusting component into a coupling state or a decoupling state, wherein the adjusting component is coupled to the first belt and the second belt in the coupled state to drive the first belt and the second belt to move relatively , And the adjustment assembly is decoupled from the first strap and the second strap in the uncoupled state, so that the first strap and the second strap can move freely relative to the adjustment assembly.

Based on the above, the head-mounted display of the present invention gradually adjusts the overlapping degree of the first strap and the second strap through the adjustment component, thereby changing the wearing space to match the size of the user's head shape, and the adjustment component is in the coupled state . In addition, the switching element can switch the adjusting element from the coupled state to the decoupled state. In the uncoupled state, the adjustment component is uncoupled from the first and second straps, so that the first and second straps can move freely relative to the adjustment component, allowing the user to quickly adjust the size of the wearing space to achieve Improve adjustment efficiency.
