The elastic member 952 may be a spring, which may be disposed between the fixed bracket 221 and the slider 930. Wherein, the end of the elastic member 952 far away from the sliding member 930 may be provided with a buffer pad 980, so that when the sliding member 930 is attracted by the electromagnetic unit 951 and the elastic member 952 is compressed, the buffer pad 980 may play a role of buffering, and noise generated when the sliding member 930 compresses the elastic member 952 is reduced.

The kinematic relationship between the slider 930 and the driving member 950 will be described by way of example in conjunction with the accompanying drawings:

when the turnover mechanism 200 moves, the electromagnetic unit 951 is in a power-on state, the sliding member 930 is attracted by the electromagnetic unit 951 and is separated from the locking groove 920, at this time, the sliding member 930 compresses the elastic member 952, the housing 210 and the locking disc 910 can rotate relative to the sliding member 930 and the rotating shaft 224, respectively, and the grating detects the rotation angle of the motor;

when the display device housing 100 rotates to a predetermined shift position, the electromagnetic unit 951 is in a power-off state, the sliding member 930 is pushed by the elastic member 952 to be clamped into one of the plurality of locking grooves 920 for locking, at this time, the sliding member 930 stops rotating relative to the rotating shaft 224, so that the housing 210 also stops rotating relative to the rotating shaft 224, and the display device housing 100 also stops rotating.

Further, the driving unit 222 stops driving, the gap between the transmission assembly 223 and the driving gear 700 is eliminated, and further the gap between the components of the transmission assembly 223 is eliminated, and the entire in-vehicle display device 1 is in a stable locked state.

Therefore, the display device housing 100 can be locked at a plurality of positions in the movement process, and the turnover mechanism 200 is stable and has no gap when the display device housing 100 stops moving, so that the display device housing 100 is prevented from shaking when the display device housing 100 stops moving.

According to some embodiments of the present invention, as shown in fig. 2, the vehicle-mounted display device 1 further includes a control board 140, and the control board 140 is disposed in the rotating shaft housing 190 and electrically connected to the driving device 220. Wherein, the control board 140 can control the current of the input motor, and the control board 140 can be connected with the grating to collect the signal fed back by the grating.

For example, the vehicle-mounted display device 1 may be provided with a protection box for protecting the control panel 140, the protection box may be installed in the housing 210 and located in the rotating shaft housing 190, the protection box may have an electromagnetic shielding function, so that the control panel 140 may be prevented from being subjected to electromagnetic interference through the protection box, and then it is ensured that the control panel 140 may work better, and the protection box may prevent the control panel 140 from being damaged by other parts.

According to some embodiments of the present invention, as shown in fig. 1, the display device housing 100 is provided with a driven shaft 110, the driven shaft 110 is connected to a rotation shaft housing 190, a central axis of the driven shaft 110 coincides with a central axis of the driving shaft 230, and the driven shaft 110 is sleeved with a torsion spring 120, and the torsion spring 120 provides an elastic force for urging the display device housing 100 to be flipped upward.

For example, when the in-vehicle display device 1 is mounted on the top of a vehicle, due to gravity, the load of the driving unit 222 (e.g., a motor) and the load direction are different during the process of turning the display device housing 100 up and down, which may generate noise, and the damping between the driving shaft 230 and the driven shaft 110, that is, the damping between the tilting mechanism 200 and the display device housing 100, may be increased by the arrangement of the torsion spring 120, so as to reduce the difference in the load of the driving unit 222 (e.g., a motor) during the process of turning the display device housing 100 up and down, thereby avoiding the generation of noise.

A vehicle according to an embodiment of the present invention, which includes an in-vehicle display device 1 according to an embodiment of the present invention, is described below with reference to the drawings.
