A passenger car pneumatic breaker

Abstract

The invention discloses a bus pneumatic breaker comprising an inflating pump, an emergency button, a breaking device, a controller, a smoke sensor, a temperature sensor, an electric control button, and a power source. The inflating pump is connected with the input end of the emergency button; the output end of the emergency button is connected with the breaking device through a second gas circuit. The smoke sensor and the temperature sensor are used for acquiring a smoke signal and a temperature signal from the inside of a bus and both electrically connected to the controller. The electric control button is disposed on an instrument table. Two ends of the electric control button are electrically connected with the power source and the controller respectively. A set smoke value and a set temperature value are set in the controller. The controller is electrically connected with the emergency button. When the smoke and temperature in the bus exceed the set smoke and temperature values or the electric control button is shut off, the controller drives the emergency button to shut off. The bus pneumatic breaker has the advantages that three independent actions are achieved through an existing gas source of the bus and safety of people is greatly improved.

Description

technical field [0001] The invention relates to the field of safe escape of passengers in passenger cars, in particular to a pneumatic breaker for passenger cars, which can effectively realize the escape of passengers by making full use of the air circuit of the passenger car, electric control resources and a new structure. Background technique [0002] With the continuous improvement of people's living standards, people's travel is more and more dependent on taking a car, and the safety of taking a car has gradually become an issue that people pay attention to. At present, there are generally three ways for passengers to escape after a safety accident in a passenger car: [0003] 1. Use a manual breaking hammer to break the glass; the advantage is that it is simple and easy to operate, but the disadvantage is that passengers need to keep calm when an accident occurs. In addition, it also requires passengers to know how to use the safety hammer, and there is a hidden danger ...

Problems solved by technology

[0003] 1. Use a manual breaking hammer to break the glass; the advantage is that it is simple and easy to operate, but the disadvantage is that passengers need to keep calm in case of an accident. In addition, it also requires passengers to know how to use the safety hammer, and there is a hidden danger of easy loss

[0004] 2. Use electronically controlled explosives to break the glass automatically. The advantage is that the blasting force is strong; the disadvantage is that due to the explosives and the validity period of the explosives, there is a risk of failure during the scrapping period of the bus, which may cause fatal accidents to the safety of passengers. Impact

[0005] 3. The electronically controlled electromagnetic automatic breaking hammer is used to break the glass; its advantage is that it can remain effective during the scrapping period of the bus, and its disadvantages are the problems of poor blasting force and safety risks due to its large size
