Operation principle and beneficial effect:
When running car, ultrasonic sensor sends ultrasound wave, ultrasound wave touches ground or the water surface then backtracking and is received signal to ultrasonic sensor by ultrasonic sensor and be converted into the signal of telecommunication and pass to microcontroller, meanwhile, the temperature signal around ultrasonic sensor is converted to the signal of telecommunication and passes to microcontroller by temperature sensor.Microcontroller is transmitted, according to ultrasonic sensor and temperature sensor, the signal come and calculates now automobile chassis and, to ground or the distance of the water surface, and this distance shown by display device.The distance relatively calculated and the safe distance pre-set, when the distance of automobile chassis to ground or the water surface is less than safe distance, microprocessor controls sound-producing device sends sound to start warning reminding driver and changes its course.This utility model can quickly detect automobile chassis and ground or the distance of the water surface, it is to avoid occurs automobile chassis to be occurred by ground scratch or situation about being soaked in water.
When ground or the water surface are sufficiently close to automobile chassis, microprocessor controls electric machine rotation, swing arm no longer abuts with connecting plate along with electric machine rotation, swing arm, connecting plate is hauled by extension spring and moves upward, and makes the temperature sensor on connecting plate avoid with ultrasonic sensor with ground or the water surface and contacts.Effectively protect temperature sensor and ultrasonic sensor.
Further, described sound-producing device is the loudspeaker that can send voice.Facilitate loudspeaker to speak the distance reminding ground, driver front or the water surface hypotelorism to automobile chassis, can advance central scratch base plate at automobile.Remind driver to change a position to spend.
Further, described display device is display screen.Microcontroller is facilitated the distance of automobile chassis to ground or the water surface to be shown by display screen, for driver's reference.
Further, described microcontroller is single-chip microcomputer.Single-chip microcomputer is the more commonly used on market, the microcontroller that Application comparison is ripe, and order used is disclosure of that on technical manual.Low price, is suitable to promote.
Further, described connecting plate is provided with the groove abutted for swing arm.Swing arm can be made to abut more stable with connecting plate by groove, only when swing arm rotates, swing arm may exit connecting plate.
Further, described mounting box is provided with the U-shaped grab can being connected on door handle.Mounting box is enable to be securely attached on the handle of arrangements for automotive doors by U-shaped grab.
Further, described mounting box is additionally provided with sucker in the one side of car door.More can be securely attached on car door on car door by sucker suction, and can avoid leaving a trace on car door by sucker suction.
Further, described extension spring is to be provided with rubber tube in the middle of helical spring, and helical spring；Described rubber tube is connected between mounting box and connecting plate.Rubber tube passes helical spring so that it is do not affect the flexible of helical spring.
Further, described temperature sensor and ultrasonic sensor have the wire being connected with microcontroller, and described temperature sensor, ultrasonic sensor and wire are arranged in rubber tube.By rubber itself, there is the elastic and feature of water proofing property, enable rubber tube along with helical spring dilatation, and be possible to prevent temperature sensor, ultrasonic sensor and wire to avoid being soaked in water.
