Problems solved by technology

However, adding an exhaust system will increase the complexity of the design and increase the volume of the exhaust pipe, resulting in a smaller ground clearance of the vehicle and reducing its carrying capacity

Abstract

The invention discloses a car chassis fire early warning system. The system comprises a mirror reflection photoelectric module,a reflection surface and an early warning module, wherein the mirror reflection photoelectric module is installed at the bottom of a chassis, is arranged right above a reflection surface, and is used for emitting light to the reflection surface and sending an early warning signal to an early warning module when the reflected light is not received; the reflection surface is arranged on an upper surface of the section of an exhaust pipe with the smallest vertical distance from the chassis, and is used for reflecting light; and the early warning module is used for carrying out early warning when receiving the early warning signal. When foreign matters enter between the chassis and the exhaust pipe, the foreign matters can be detected and prompted to be cleared by a driver so as to nip in the bud.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a car chassis fire warning system. Background technique [0002] With the increasing number of passenger cars in the market, there are more and more passenger car fire accidents. In view of this, it is necessary to develop various fire protection systems to ensure the safety of passengers and drivers. The chassis of passenger cars is relatively low. On ordinary roads, foreign objects (such as plastic films, hay, and paper scraps) often appear in the space between the chassis and the exhaust pipe. When the engine is running under heavy load conditions, the temperature of the exhaust pipe will increase. Gradually rising, as the exhaust temperature rises, the inclusion of foreign matter may spontaneously ignite, which in turn will cause the entire vehicle to spontaneously ignite. The current plan uses a wrapped heat shield for the exhaust pipe to reduce its surface ...
