This application discloses a charging device and a charging system. The charging device includes a communication controller. The communication controller is configured to be connected to communications controllers of at least two vehicles, and the charging device is configured to charge the vehicle in a case that communications is established between the communication controller and the communications controller. In the charging device and the charging system of the implementations of this application, the communication controller can be connected to at least two communications controllers, and the charging device can charge the vehicle in a case that communications is established between the communication controller and the communications controller. Therefore, compared with a case that the communication controller is communicatively connected one-to-one to the communications controller, this application requires only one communication controller to implement communications connection with the at least two communications controllers. A quantity of communication controllers is relatively small, which can not only reduce a production cost of the charging device, but also reduce a volume of the charging device, thereby helping to implement miniaturization of the charging device.

The present disclosure provides a motor control system and a vehicle. The motor control system (1) includes a motor drive module (10), a multi-core processing module (20), and a safety logic module (30). The multi-core processing module (20) includes a main function core (21) and a lockstep monitoring core (22). The main function core (21) is configured to obtain sampling data, and when any one of the sampling data, a running status of the main function core (21), a motor control signal, and a running status of a motor is abnormal, the lockstep monitoring core (22) outputs a safety trigger signal; and the safety logic module (30) is configured to output an instruction for prohibiting execution of the motor control signal to the motor drive module (10) when receiving the safety trigger signal.

An actuator for adjusting a display terminal and a vehicle are provided. The actuator includes: a mounting unit (10), the mounting unit (10) includes a rotating turntable (13) and a mounting shaft (15), one end of the rotating turntable (13) is configured to mount the display terminal (200), another end of the rotating turntable is fixedly connected to the mounting shaft (15); a drive unit (30), the drive unit (30) is configured to drive the mounting unit to rotate; and an elastic member (40), the elastic member is sleeved on the mounting shaft, and one end of the elastic member abuts to the axial limiting member (42), and the other end of the elastic member abuts to the housing of the drive unit.
