Abstract
An electromotive reversing car camera , especially a electromotive reversing car camera mounted in a car number plate. When the car is not actuated, the camera can be closed automatically for avoiding to be destroyed. When the car is actuated, the lens of the camera is opened for monitoring the rear side condition of the car by the driver so as to assist the monitoring the dead point which can not be viewed through the back view mirrors of the car. When the car is entered into a reverse (R) stage, the lens of the camera can be moved downwards for monitoring the condition of the load for avoiding collision with a child or other dangerous object. The functions of the present invention is that as the car is stopped, the camera is protected from damaged. When the car is actuated, the lens of the camera can be opened and moved automatically for taking a photograph. Further, the image can be transferred to a monitor for being viewed by the driver to adjust the condition of the load so as to drive safely.
