Abstract

A head-mounted display device includes a front piece and an annular piece. The front piece is adapted for placing a display device. The annular piece includes a pair of compression portions and a pair of rotating portions. The pair of rotating portions are respectively located at two opposite ends of each of the pair of compression portions. The annular piece is connected to the front piece via the pair of compression portions. When the pair of compression portions are compressed toward the front piece, the pair of rotating portions are adapted to be rotated relative to the pair of compression portions by the pair of compression portions being compressed, and rotation directions of the pair of rotating portions are opposite to each other.

First claim

2 . The head-mounted display device according to claim 1 , wherein the front piece has an accommodation space, and the annular piece is disposed in the accommodation space.

3 . The head-mounted display device according to claim 2 , wherein the front piece further comprises at least one guide piece, and the at least one guide piece makes the pair of rotating portions in rotation slide according to the at least one guide piece.

4 . The head-mounted display device according to claim 3 , wherein the at least one guide piece has at least one guide bevel, and the at least one guide bevel inclines toward the annular piece in a direction from adjacent to the pair of compression portions to away from the pair of compression portions.

5 . The head-mounted display device according to claim 4 , wherein the guide bevel has different slopes in different positions.

6 . The head-mounted display device according to claim 3 , wherein the at least one guide piece has a guide rail, each of the rotating portions comprises a connecting rod portion, one end of the connecting rod portion is pivotally connected to the guide rail, and the pair of rotating portions are adapted to be rotated by the connecting rod portion sliding in the guide rail.

7 . The head-mounted display device according to claim 1 , wherein the annular piece further has at least one connection portion, and the at least one connection portion is connected between the pair of compression portions and the pair of rotating portions to form a gap.

8 . The head-mounted display device according to claim 7 , wherein the at least one connection portion is a U-shaped structure and has a second opening, the second opening facing toward a side away from the front piece, and the pair of rotating portions are adapted to be bent toward the second opening by the pair of compression portions being compressed.

9 . The head-mounted display device according to claim 7 , wherein the at least one connection portion is a hinge structure, such that the pair of rotating portions pivot relative to the pair of compression portions with the hinge structure.

10 . The head-mounted display device according to claim 1 , wherein the pair of compression portions are a honeycomb-shaped hollow structure.

11 . The head-mounted display device according to claim 1 , wherein the pair of compression portions comprise a bearing portion and at least one spring structure, and the at least one spring structure is disposed between the bearing portion and the front piece.

12 . The head-mounted display device according to claim 1 , wherein the pair of compression portions or the pair of rotating portions have a bellow tube structure.
