Automobile fuel tank

Abstract

The invention belongs to the technical field of oil tanks, and particularly relates to an automobile fuel tank. The automobile fuel tank comprises an oil tank shell, an anti-damage mechanism, an oil inlet pipe, a shockproof mechanism, a protection mechanism and an anti-collision mechanism, wherein the anti-damage mechanism is arranged in the oil tank shell; the anti-damage mechanism comprises an inner container, a mounting gap, rubber balls and deoxygenated water; the inner container is installed in the oil tank shell. A plurality of evenly-distributed rubber balls are fixedly embedded in theouter wall of the inner container. Each rubber ball is fixedly embedded with the inner wall of the oil tank shell. An installation gap is reserved between the inner container and the oil tank shell and filled with enough deoxygenated water, the oil inlet pipe is installed on the upper surface of the oil tank shell, and a dust blocking mechanism used for preventing dust from entering the inner container is installed in the oil inlet pipe. The automobile fuel tank provided by the invention has the advantages of dust prevention and shock absorption functions.

Description

technical field [0001] The invention belongs to the technical field of fuel tanks, in particular to an automobile fuel tank. Background technique [0002] Automotive fuel tanks are divided into materials; iron fuel tanks and aluminum alloy fuel tanks. With the application and development of various new materials, the rust prevention of iron fuel tanks has become the biggest problem in the quality of fuel tanks. Especially in today's environment-friendly work. In terms of heavy trucks: During the promotion of National 45 vehicles, the problem that affects the promotion of new models is the quality of Chinese oil, among which the quality of the fuel tank that holds the fuel has become the key point. The aluminum alloy fuel tank not only can meet the strength direction but also has great advantages in corrosion resistance than iron and other new materials. It has also become the first choice for large buses and heavy trucks that consume a lot of fuel and require high fuel qua...

AI Technical Summary

Problems solved by technology

[0003] When the fuel tank on a large heavy truck is refueled, the dust raised by the fuel tank when the pipe cover is opened or closed is easy to enter the fuel tank, resulting in the formation of dirt in the fuel tank that is difficult to remove, which will affect the formation after a long time Precipitation, etc. make the quality of the oil poor, which affects the running condition of the engine and causes damage to the engine. At the same time, after a car accident, the damage of the fuel tank may cause secondary damage
