Embodiment Construction

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help the understanding of the present invention, but do not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as there is no conflict with each other.

[0025] like figure 1 As shown, the present invention provides a car chassis fire warning system, comprising:

[0026] The mirror reflection photoelectric module is installed on the bottom of the chassis 2, and is arranged vertically corresponding to the reflective surface 4, and is used to emit light to the reflective surface 4, and sends an early warning signal to the early warning module 5 when the reflected light is not received; The reflected light means that at...

Abstract

The invention discloses a car chassis fire warning system. It includes a mirror reflective photoelectric module, which is installed on the bottom of the chassis, arranged vertically and vertically to the reflective surface, and is used to emit light to the reflective surface, and send an early warning signal to the early warning module when no reflected light is received; The upper surface of a section of the exhaust pipe with the smallest vertical distance between the chassis is used for reflecting light; the early warning module is used for early warning when an early warning signal is received. The invention can detect and prompt the driver to remove foreign matter when it enters between the chassis and the exhaust pipe, so as to prevent problems before they happen.

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 fire accidents in passenger cars. In view of this, various fire protection systems need to be developed to ensure the safety of passengers and drivers. The chassis of passenger cars is low. On general roads, foreign objects (such as plastic films, hay, and paper scraps) are often included 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, thereby causing the entire vehicle to spontaneously ignite. The current solution uses a wrap-type heat shield in the exhaust pipe to reduce its surface temperature ...
