Compared with the prior art, the invention has the advantages that:

1. in the invention, the abnormal sound in the cab can be detected by the arranged sound detection sheet, when a high-energy sound wave appears, the sound energy is received by the sound detection sheet and is converted into an electric signal by the amplifier, in the invention, two sides of the brake box are respectively provided with the sound detection sheet, so that two currents are generated and input to the two conductive plates, and the two conductive plates generate a potential difference;

2. the two conductive plates are positioned in the grooves in the sliding plate group and are sealed, so when the two conductive plates are electrified, an approximate parallel plate capacitor is formed, and the current generated by the sound detection sheet is collected in the parallel plate capacitor, so that the advantage that the difference between normal noise and high-decibel noise before an accident is distinguished through the current collection effect is achieved, namely, the high-decibel sound volume in a very short time generated in a vehicle does not play a role in the invention;

3. when the voltage is continuously increased at the two ends of the parallel plate capacitor, namely, the sound in the automobile is continuously generated, the parallel plate capacitor formed by the two conductive plates is broken down, at the moment, the current passes through the medium between the parallel plate capacitors, the extremely high electric heat is generated in a short time, and the evaporating liquid serving as the insulating medium is heated to the extremely high temperature instantly, so that the evaporating liquid is gasified in the space to generate higher air pressure;

4. the air pressure acts inside the sealed groove, so that the magnetic force of mutual attraction of the two magnetic layers and the elastic force of the spring can be overcome, the first plate body and the second plate body move away from each other, the first plate body at one end of the spring compresses the spring at the moment, and the effect of rapid braking of the brake is realized, so that the advantage that the brake can be braked in a short time without applying force by feet of a driver is realized;

5. the two sealing strips are arranged in the second plate body in a penetrating mode, and the function of the invention is that after the two plate bodies are respectively far away, gas evaporated by the evaporating liquid in the groove cannot be discharged due to the existence of the sealing strips, and then the evaporated liquid after the temperature is recovered to be normal is liquefied into liquid again and is continuously stored in the groove, so that the use for the next time is convenient.
