The embodiment of the invention provides a dynamic projection device and a vehicle tail door opening and closing control method, and the dynamic projection device is installed on a vehicle body and comprises a shell, a first light machine, a second light machine and a control circuit board. The shell is installed on a vehicle tail door and comprises a first window and a second window which are arranged in a spaced mode in the first direction. The first light machine and the second light machine are arranged in the shell, the first light machine emits light through the first window to project a first pattern, and the second light machine emits light through the second window to project a second pattern; a preset included angle is formed between the main light ray direction emitted by the object plane center of the first light machine and the main light ray direction emitted by the object plane center of the second light machine, so that the projection areas of the first light machine and the second light machine are overlapped; the control circuit board is electrically connected with the vehicle control system, the first light machine and the second light machine, and the control circuit board is used for controlling the first light machine and the second light machine to be alternately started according to preset time so as to alternately project a first pattern and a second pattern in the projection area.

    本发明实施例提供了一种动态投影装置及车辆尾门开关控制方法,动态投影装置安装于车体,包括外壳、第一光机、第二光机和控制电路板。外壳安装于车辆尾门上,外壳包括沿第一方向间隔布置的第一窗口和第二窗口;第一光机和第二光机设于外壳内,第一光机通过第一窗口出射光线,以投影出第一图案,第二光机通过第二窗口出射光线,以投影出第二图案;第一光机的物面中心发射的主光线方向与第二光机的物面中心发射的主光线方向具有预设夹角,以使第一光机与第二光机的投影区域重合;控制电路板与车辆控制系统及第一光机、第二光机电连接,控制电路板用于根据预设时间控制第一光机和第二光机交替开启,以在投影区域交替投影出第一图案和第二图案。
