It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0041] As described in the background technology, Figure 1 As shown, Figure 1 This is a schematic diagram of a ceiling screen configuration according to an exemplary embodiment. Currently, a large-sized ceiling screen is configured on the ceiling of the vehicle to facilitate rear passengers to watch videos. Currently, when front passengers watch the content played on the ceiling screen, they need to sit in the back seats to watch.

The device 20 includes: a ceiling screen 201. A first rotating shaft 202, one end of which is connected to one side of the ceiling screen 201, and a second rotating shaft 203, one end of which is connected to the other side of the ceiling screen 201. A first connecting member 204, one end of which is rotatably connected to the other end of the first rotating shaft 202, and a second connecting member 205, one end of which is rotatably connected to the other end of the second rotating shaft 203. The first rotating shaft 202 and the second rotating shaft 203 are configured to flip the ceiling screen 201.

[0043] The connecting member in the embodiment of the present application may be a suspension rod or a suspension column, which is not limited in the embodiment of the present application.

[0044] According to the above technical means, the ceiling screen control device 20 includes a first connecting member 204, a second connecting member 205, a first rotating shaft 202, a second rotating shaft 203 and a ceiling screen 201. In this way, rotatable connecting members are arranged on both sides of the ceiling screen 201, and the ceiling screen is flipped by the first rotating shaft 202 and the second rotating shaft 203. Therefore, when the passengers in the front seats need to watch the ceiling screen, the ceiling screen 201 is flipped by the first rotating shaft 202 and the second rotating shaft 203 to realize the turning of the ceiling screen 201, and the front passengers can also see the display content of the ceiling screen 201 in the front seats, and the display content of the ceiling screen 201 can be seen without the front passengers changing seats.

[0045] One possible approach is Figure 3 As shown, the ceiling screen control device 20 further includes a sliding assembly 206 for being installed on the vehicle body. In the direction of the rotation axis of the first rotating shaft 202, the other ends of the first connecting member 204 and the second connecting member 205 are slidably connected to the sliding assembly 206; the first connecting member 204 and the second connecting member 205 are installed on the vehicle body through the sliding assembly 206.

[0046] In order to better understand the installation position of the sliding assembly 206, as shown in FIG. Figure 4 As shown, Figure 4 FIG. 2 is a schematic diagram showing the installation position of a sliding assembly 206 on a vehicle according to an exemplary embodiment. Figure 4 In the embodiment, the sliding assembly 206 is between the front row seat and the back row seat.
