The utility model provides a vehicle-mounted ceiling screen device and a vehicle. The vehicle-mounted ceiling screen device comprises a first rail mechanism, a second rail mechanism and a sliding mechanism. The second rail mechanism is connected to the first rail mechanism and can slide on the first rail mechanism in the first direction, and the first direction is the length direction of the vehicle; the sliding mechanism is connected to the second rail mechanism and can slide on the second rail mechanism in the second direction, the second direction is the width direction of the vehicle, and the sliding mechanism is used for being connected with a display screen. According to the technical scheme, the vehicle-mounted ceiling screen can be moved during use, the watching requirements of passengers on different seats are met, and the use experience of the passengers is improved.

The utility model discloses an external hanging type technical personnel examination peep-proof screen device, and mainly relates to the field of examination facilities. Comprising vertical plates vertically arranged on the two sides of the displayer, the vertical plates vertically extend and are arranged in parallel, a back plate located on the rear side of the displayer is arranged on one sides of the vertical plates, a right-angle internal corner is formed between the vertical plates and the back plate, a top plate is fixed to the top end of the internal corner, and a sleeve is fixed to the rear side of the back plate. A connecting rod penetrates through the sleeves on the two sides, a protruding block is arranged at one end of the connecting rod, the other end of the connecting rod is in threaded connection with a first rotary knob, a shaft sleeve sliding in the width direction of the vertical plate is arranged on the top side of the vertical plate, and a check ring is arranged at the inner end of the shaft sleeve. And the elastic piece has elastic force for enabling the shaft sleeve to move towards the back plate. The beneficial effects of the utility model reside in that illegal actions of adjacent examinees can be effectively prevented, and sufficient observation space can be provided for invigilators above the display.

The present disclosure provides methods and apparatuses for multi-screen management. In some implementations, a plurality of connection requests may be received from a plurality of screen devices respectively. A screen host unit corresponding to each screen device may be created. A connection of each screen host unit to a corresponding screen device may be established. Screen display data may be transmitted, by at least one screen host unit, to at least one corresponding screen device through at least one corresponding connection respectively. Moreover, in some implementations, a connection request may be transmitted to a screen management hub. A connection to a corresponding screen host unit created by the screen management hub may be established. Screen display data may be received from the screen host unit through the connection. The screen display data may be displayed.

The ceiling screen device and the vehicle are applied to the field of vehicles, the ceiling screen device comprises a mounting frame, a shell is arranged on the mounting frame, a main rotating shaft is rotationally connected into the shell and arranged on a display screen, and a driving unit used for driving the main rotating shaft to rotate is arranged on the mounting frame; and a damping unit for eliminating a transmission gap of the main rotating shaft is arranged on the mounting frame. The folding display screen has the technical effects that the driving unit is started, the driving unit drives the main rotating shaft to rotate, the main rotating shaft drives the display screen to move to achieve folding of the display screen, the damping unit is used for eliminating a transmission gap generated after the main rotating shaft is durable, the possibility of shaking of the display screen is reduced, and the operation stability during folding of the display screen is improved.

The invention provides a hinge state detection method of folding screen equipment and the folding screen equipment, relates to the technical field of terminals, and can enable a user to know the state of a hinge and obtain better use experience. According to the method, the folding screen device obtains sensor data collected by at least one sensor in the process that a foldable display screen is opened and closed, the sensor data at least comprises acoustic data of a hinge and / or angle data of the hinge, the acoustic data is from a sound sensor in the at least one sensor, and the angle data of the hinge is from the sound sensor in the at least one sensor. The angle data originates from an angle sensor of the at least one sensor. Afterwards, the folding screen device obtains the state detection result of the hinge according to the sensor data, the hinge state can be detected without using an external hinge detection device, a user can conveniently know the real state and the prediction state of the hinge of the folding screen device in time, and better use experience is brought to the user.
