Escape system for a sinking car and ultrasonic component thereof
First Claim
1. An ultrasonic component, at least comprising:
- a case having a housing space therein, at least one side of the case has at least a perforation, and two sides of the perforation have at least two masking pieces being disposed corresponding to the two sides of the perforation, wherein the masking piece and the side of the case have an angle therebetween; and
an ultrasonic module disposed in the housing space, the ultrasonic module comprises an ultrasonic signal transmitting unit, a receiving unit, a calculating unit electrically connected to the receiving unit and a signal transmitting unit electrically connected to the calculating unit;
wherein the ultrasonic signal transmitting unit emits an ultrasonic, the receiving unit receives the ultrasonic;
the receiving unit analyzes a speed of the ultrasonic and converts the speed of the ultrasonic to a transmittance rate,the receiving unit analyzes a speed of the ultrasonic and converts the speed of the ultrasonic to a reflection rate, or the receiving unit analyzes a time deviation between a time which the ultrasonic signal transmitting unit emits the ultrasonic and a time which the receiving unit receives the ultrasonic, or the receiving unit analyzes a reflection distance according to the time deviation;
the calculating unit compares the transmittance rate sent from the receiving unit to a built-in transmittance rate set value,the calculating unit compares the reflection rate sent from the receiving unit to a built-in reflection rate set value, or the calculating unit compares the time deviation sent from the receiving unit to a built-in time deviation set value, or the calculating unit compares the reflection distance sent from the receiving unit to a built-in reflection distance set value;
when the transmittance rate is different from the built-in transmittance rate set value,when the reflection rate is different from the built-in reflection rate set value, or when the time deviation is different from the built-in time deviation set value, or when the reflection distance is different from the built-in reflection distance set value, the calculating unit generates a warning signal which indicates a car has been fallen into water to a signal transmitting unit, and the signal transmitting unit transmits the warning signal via a wired manner or a wireless manner;
wherein the ultrasonic has a transmittance wave, when the receiving unit analyzes a speed of the transmittance wave is larger than the speed of the ultrasonic, the receiving unit analyzes the reflection rate by using an equation as follows;

Abstract
An escape system for a sinking car and an ultrasonic component thereof are illustrated. In the present disclosure, an ultrasonic signal transmitting unit capable of emitting ultrasonic is installed on the car. When the car falls into the water, based upon an acoustic resistance concept which the ultrasonic propagated in air collides and transmits into the water, a difference between a reflection or transmittance rate of the ultrasonic and a corresponding set value can be calculated, or alternatively, a difference between a reflection time deviation or a reflection distance of the ultrasonic and a corresponding set value can be calculated. Therefore, a warning signal indicating that the car falls into the water can be fast sent, and this makes sure that the rescue opportunity which the car falls into the water can be grasped to decrease the damage or death of the user.
