A gas discharge device in an automobile body and a fuel cell automobile to which it is applied

Abstract

The invention discloses a device for discharging the gas in an automobile body. The device comprises an automobile spoiler, a trunk lid and a support, wherein the automobile spoiler is fixed on the trunk lid through the support, a vent hole communicated with the atmosphere is opened on the support, and an air hole communicating the inside of the automobile body with the vent hole is arranged on the trunk lid. According to the device for discharging the gas in the automobile body, hydrogen in the automobile body is discharged into the atmosphere automatically through the air hole on the trunk lid and the vent hole on the support, a vehicle-mounted hydrogen bottle is placed in a trunk, and the device is arranged at the top of the vehicle-mounted hydrogen bottle, so that timely discharge of the hydrogen in the automobile body is facilitated; on the other hand, only the air hole and the vent hole are needed to be opened on the trunk lid and the support respectively, so that the structure is simple; and the hydrogen can be discharged from the automobile body automatically due to the atmospheric pressure, accordingly, the safety performance is high, and energy consumption is reduced simultaneously.

Description

technical field [0001] The invention relates to the technical field of automobile design, in particular to a gas discharge device in an automobile body. The present invention also relates to a fuel cell automobile comprising the above-mentioned gas discharge device in the automobile body. Background technique [0002] With the increase of the number of vehicles in the world, most of the cars currently drive cars by burning oil. However, the supply of oil as a non-renewable resource is in short supply, and the price of oil is increasing day by day, and the exhaust gas emitted by cars is also polluting the environment. More and more seriously, the exhaust gas emitted by automobiles contains a large amount of carbon dioxide, which leads to global warming. Therefore, fuel cell vehicles have become a new generation of clean transportation for human beings. [0003] As a type of electric vehicle, fuel cell vehicles generate electricity to drive the power system through the electr...

Problems solved by technology

[0004] When the car is running, when the power generation system in the car generates electricity, the on-board hydrogen bottle needs to transport hydrogen to the outside. During the above process, the hydrogen may leak into the car body. Since hydrogen is a flammable gas, when the concentration of hydrogen in the car body reaches To a certain extent, an explosion may occur when encountering an open flame, seriously affecting the personal safety of the passengers

[0005] The traditional gas discharge device in the car body is to add an air extraction device in the trunk of the car to extract the gas in the car body and discharge it to the outside of the car body. However, the air extraction device needs to provide electric energy before it can work. , when the air extraction device is working, the power supply system of the car needs to provide electric energy to the air extraction device alone, which increases the workload of the car; Or when the wiring is ignited, there is hydrogen in the car body, which is prone to explosion, which seriously affects the personal safety of the passengers.
