And the side wall is provided with the heat dissipation holes 7, so that the heat dissipation effect can be achieved.

The fixed plates 2 are symmetrically arranged, the fixed plates 2 are installed in the screen throwing outer cover 1, and an installation area 8 is formed in the middle of the symmetrically arranged fixed plates 2. VR device 39 is placed in the mounting area 8.

The turnover part 3 is arranged in the installation area 8, the turnover part 3 is connected with the fixed plate 2 through the rotating shaft 9, and the turnover part 3 is provided with an installation part 10 for placing VR equipment 39. The overturning piece 3 is provided with a dovetail groove 11, the mounting piece 10 is provided with a dovetail block 12 matched with the dovetail groove 11, and the dovetail block 12 is provided with a fixing bolt 13. The height of the turnover piece 3 can be lengthened according to actual conditions, the dovetail blocks 12 are mounted at different positions in the dovetail groove 11, VR devices 39 with different heights can be mounted on the mounting piece 10, and the turnover piece is suitable for mounting VR devices 39 with different models.

The turnover assembly 4 is arranged in the screen throwing housing 1, and the turnover assembly 4 is provided with a turnover motor 14, a symmetrically arranged movable plate 15 and a first belt 16. The first belt 16 is installed on the inner wall of the screen throwing housing 1 through a rotating shaft 17, the rotating shaft 17 is arranged at the upper end and the lower end of the middle of the first belt 16, the first belt 16 can be unfolded and is in a flat state, and the overturning motor 14 is connected with one rotating shaft 17.

The movable plate 15 is connected with the first belt 16 through the connecting part 18, the connecting parts 18 are respectively arranged on the movable plate 15 and the first belt 16, and the middle is connected through the mounting shaft 19, so that when the first belt 16 rotates, the movable plate 15 is ensured to be driven by the first belt 16 to change positions and angles.

The first belt 16 is located between the fixed plate 2 and the inner wall of the screen projection housing 1, the movable plate 15 is provided with a driving part 20, and two ends of the rotating shaft 9 are provided with transmission parts 21 matched with the driving part 20. When the first belt 16 drives the movable plate 15 to change positions, the driving part 20 drives the transmission part 21, and the movable plate 15 moves between the first belt 16 and the inner wall of the screen projection housing 1.

The fixed plate 2 is provided with a bar-shaped hole 22, the rotating shaft 9 is positioned in the bar-shaped hole 22, and the height of the bar-shaped hole 22 is larger than the distance between the limiting part 23 and the movable part 27. The mounting part 10 is provided with a limiting column 24, the fixed plate 2 is provided with a limiting groove 25, the limiting groove 25 consists of an arc-shaped part 26, a movable part 27 and a limiting part 23, and the limiting column 24 is positioned in the limiting part 23. A blocking part 28 is arranged between the limiting part 23 and the arc-shaped part 26, and the blocking part 28 is used for limiting the position of the limiting column 24. The movable plate 15 is provided with a through groove 29, and the driving part 20 is positioned on the inner wall of the through groove 29. The length of the driving part 20 is 2/3 of the length of the through groove 29. The driving part 20 is a rack, and the transmitting part 21 is a tooth.

Since the length of the driving part 20 is 2/3 of the length of the through groove 29, when the movable plate 15 is converted from the vertical state to the vertical state, the transmission part 21 is first made to enter the through groove 29, but is not engaged with the driving part 20. Only if the turnover motor 14 is enabled to continuously drive the first belt 16 to rotate, the first belt 16 is enabled to continuously drive the movable plate 15 to move, the transmission part 21 can be meshed with the driving part 20, and therefore the driving part 20 on the movable plate 15 drives the transmission part 21.

In addition, since the driving part 20 is a rack, the transmission part 21 is a tooth, and the limiting post 24 on the mounting member 10 is located in the limiting part 23, the positions of the turning member 3 and the mounting member 10 are limited, and the driving part 20 only pushes the transmission part 21 upwards at this time, so that the rotating shaft 9 is pushed from the position b to the position a in the bar-shaped hole 22. When the turnover element 3 is pushed upwards, the limiting column 24 on the installation element 10 is pushed upwards, so that the limiting column 24 enters the movable part 27 from the limiting part 23, the limiting column 24 breaks away from the constraint of the limiting part 23, the transmission part 21 is driven to rotate by the driving part 20, the rotating shaft 9 drives the turnover element 3 and the installation element 10 to rotate, and the limiting column 24 moves along the track of the arc-shaped part 26, so that the turnover element 3 and the installation element 10 rotate by 90 degrees or less than 90 degrees.

When the turnover motor 14 rotates reversely, the VR device 39 is driven to be accommodated in the installation area 8.

A driving component 5 is also arranged in the screen throwing outer cover 1, and the driving component 5 is used for assisting the overturning motor 14 to push the movable plate 15 to be unfolded. The driving assembly 5 is provided with a driving motor 30, a blocking block 31, a mounting block 32 and a pushing rod 33, and the driving motor 30, the blocking block 31 and the mounting block 32 are arranged on the inner wall of the screen projection housing 1. The driving motor 30 is provided with a main gear 34, the pushing rods 33 are symmetrically arranged, one pushing rod 33 is provided with a slave gear 35, and the other pushing rod 33 is connected with the driving motor 30 through a second belt 36. One end of the push rod 33 away from the driving motor 30 is in contact with the blocking block 31 and the movable plate 15. The movable plate 15 is provided with a cambered surface portion 37 which is matched with the pushing rod 33.

One end of the push rod 33 is provided with a drive shaft 38, the drive shaft 38 on one push rod 33 is connected to the drive motor 30 via a second belt 36, and the drive shaft 38 on the other push rod 33 is in meshed connection with the main gear 34 on the drive motor 30 via a slave gear 35. So that the driving motor 30 can drive the two pushing rods 33 to rotate, and the movable plate 15 is pushed by the pushing rods 33, which is beneficial to opening the symmetrically arranged movable plates 15. And simultaneously, the cambered surface part 37 on the movable plate 15 is matched to enable the movable plate 15 to be unfolded.

When the automatic turning device is used, the turning motor 14 can be controlled by the controller, so that the turning motor 14 rotates, the turning angle of the turning piece 3 is controlled, and the screen throwing angle of the VR equipment 39 can be adjusted according to the actual situation of a user.
