The hollow position created after the shift keeps the display stand 1 flat, and the back panel 402 and the armrest 403 are rotated with the cooperation of the joint hinge 404 to form a seat 4 with the seat panel 401. The user sits on the seat 4 to experience the VR device. The electric telescopic rod 503 is controlled to extend and retract according to the experience requirements through the VR device, and the seat 4 is ensured to swing at any angle with the cooperation of the universal joint 504, the arc groove 501, and the rotating ball 502, so that the VR user can better experience the VR device. When the content to be displayed requires the user to stand and use it, the seat 4 can be reset, and then the motor 605 can be reversed. According to the above steps, the seat 4 is moved down to the position of the closed plate 9, so that the display stand 1 remains flat, which is convenient for the user to stand and experience the VR device.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
