Embodiment 1

[0036] see figure 1 , in order to facilitate understanding, the external structure and internal structure of the fuel tank are shown in figure 1 , but the specific positions of each structure may be subject to the actual description.

[0037] This embodiment provides a fuel tank assembly, including: a stainless steel shell 1 and a carbon tank 2, the top of the stainless steel shell 1 is provided with a valve body 3 and a liquid vapor separator (Liquid vapor separator, referred to as LVS) 4, stainless steel The housing 1 is also provided with an exhaust pipe joint 5, the outlet of the valve body 3 communicates with the inlet of the liquid collector 4 through a pipeline, and the outlet of the liquid collector 4 communicates with one end of the exhaust pipe joint 5 through a pipeline. The other end of the air pipe joint 5 communicates with the carbon canister 2 through an exhaust pipeline 6 .

[0038] In the above-mentioned fuel tank assembly, the stainless steel shell 1 is inc...

Embodiment 2

[0079] This embodiment provides an automobile, which includes the fuel tank assembly in the above embodiment.

[0080] see figure 1 , the above-mentioned fuel tank assembly is applied in automobiles, including a stainless steel shell 1, which is used as a fuel tank body. Compared with the low-carbon steel shell in the prior art, the stainless steel plate material When the thickness reduction rate reaches 10%, the yield strength increases from the original 280MPa to 480MPa, that is, through work hardening, under the same strength requirements, the plate thickness of the low carbon steel shell needs to be 1.4mm ~ 1.7mm, while the stainless steel shell The plate thickness of the body 1 only needs to be 0.8mm~1.2mm, so that the thickness of the shell plate can be reduced. Taking a fuel tank with a rated volume of 50L as an example, the weight of the assembly can be reduced to about 12.5Kg, realizing the lightness of the fuel tank. Quantification, thereby reducing the weight requi...

Abstract

The invention provides a fuel tank assembly and an automobile. The fuel tank assembly comprises a stainless steel casing and a carbon canister, wherein the top of the stainless steel casing is provided with a valve body and a liquid collector and is also provided with an exhaust pipe joint, an outlet of the valve body is communicated with an inlet of the liquid collector through a pipeline, an outlet of the liquid collector is communicated with one end of the exhaust pipe joint through a pipeline, and the other end of the exhaust pipe joint is communicated with the carbon canister through an exhaust pipeline. The fuel tank assembly can reduce production cost.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a fuel tank assembly and an automobile. Background technique [0002] The fuel tank is a special container for storing fuel on the car, and it is one of the important parts of the car. [0003] The fuel tank includes the shell and the parts inside the shell. The common shell is usually a low-carbon steel shell. In order to meet the strength requirements of the fuel tank, the thickness of the shell is generally 1.4mm to 2.0mm. Taking a fuel tank with a volume of 50L as an example, its assembly weight can reach 22.5Kg, which invisibly increases the weight requirement of the whole vehicle and invests in production costs. Moreover, the exterior of the low-carbon steel shell needs to be sprayed with paint or glue for anti-corrosion treatment. In order to avoid the failure of the internal parts of the shell during the spraying and baking process, it is necessary to en...
