Abstract
The invention provides an automobile microwave prompting device for prompting cars and people in the outside world when opening a car door. The prompting device is provided with a prompting horn, a plurality of microwave radar switches, a plurality of spring dynamic breaking button switches, a remote control power switch and a power supply. The microwave radar switches are firstly connected in parallel through a circuit, and then the prompting horn, the spring dynamic breaking button switches, the remote control power switch and the power supply are connected in series through electric circuits in sequence after the spring dynamic breaking button switches are connected in parallel through a circuit. The automobile microwave prompting device for prompting the cars and people in the outsideworld when opening the car door has the beneficial effects that when an automobile is paused to open the door, if people and the cars appear on the front part, the rear part and the side part outsidethe car door, when people in a car open the car door slightly, the prompting horn can give a prompting sound to prompt people opening the car door to pay attention to external vehicles or pedestrians,and collision of other vehicles or pedestrians with the car door caused by car door opening is avoided.
