Problems solved by technology

[0005] The disadvantage of the above method is that only the built-in connection or fixing of a single part is realized, and the structure and process of connecting or fixing each part to the metal fuel tank are different, resulting in a large number of parts and many processes involved in the production process of the metal fuel tank. There are many fixtures and fixtures, and the process takes a long time
[0006] Under the industry trend of energy saving and emission reduction, plug-in or range-extended hybrid vehicles have emerged as the times require, and the use of closed fuel tanks has become one of the technical solutions for hybrid vehicles. However, due to changes in ambient temperature and the volatile characteristics of the fuel itself, closed A large range of pressure changes occurs inside the fuel tank, and strengthening the strength of the fuel tank and reducing deformation under pressure have become difficult problems to be solved in this technical field

Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, the built-in integrated assembly for the metal fuel tank and the metal fuel tank include: the integrated assembly 1, the integrated assembly 1 is a thin plate structure, and the thin plate structure includes three parts, which are respectively the connection platform 11, the support plate 12 and the plug-in The connection platform 13, the connection platform 11 is used to connect with the shell of the metal fuel tank 4, the support plate 12 is arranged with a bracket 12a for connecting the valve 5, and the support plate 12 is arranged with an insertion hole 12b for The connecting pipeline 6, the plug-in platform 13 is arranged with a plug-in structure 13a, which is used for plugging a plurality of integrated assemblies 1 with each other. Inside box 4.

[0037] The metal fuel tank 4 can be built with a single integrated assembly 1 or a plurality of integrated assemblies 1 and the plurality of integrated assemblies are plugged in...

Embodiment 2

[0039] Such as figure 1 As shown in and 4, the connection platform 11 is arranged in multiple directions of the integrated assembly 1 to realize the connection between the integrated assembly 1 and the upper shell 2 or the lower shell 3 of the metal fuel tank 4 in at least two or more directions. The connection is fixed to realize the reliable fixing of the integrated assembly 1 connected in the metal fuel tank 4 .

Embodiment 3

[0041] Such as figure 1 As shown, the end of the connection platform 11 is designed to be semicircular or arc-shaped, and is spaced at a specific distance to realize the positioning of the connection point with the metal fuel tank 4 . When the tooling is connecting the integrated components and the shell, you can directly choose the semicircle or arc center position for connection.

Abstract

The invention discloses a built-in integrated assembly for a metal fuel tank and the metal fuel tank. The integrated assembly is a thin plate structure. The thin plate structure comprises three parts,namely a connecting platform, a supporting plate and an insertion platform, wherein the connecting platform is used for being connected with a shell of the metal fuel tank, the supporting plate is provided with a support, the support is used for being connected with a valve, the supporting plate is provided with an inserting hole, the inserting hole is used for being connected with a pipe clamp for fixing a pipeline, the inserting platform is provided with an inserting structure used for mutual inserting of a plurality of integrated assemblies, and the integrated assemblies are arranged in the metal fuel tank. According to the scheme, the number of parts in the production process of the metal fuel tank, the production technological process and the tool clamp are reduced, and the strengthof the metal fuel tank is enhanced.

Description

technical field [0001] The invention relates to a metal fuel tank, in particular to a built-in integrated assembly for the metal fuel tank and the metal fuel tank. Background technique [0002] In order to reduce the permeation emissions of substances such as hydrocarbons and reduce punching holes on the metal fuel tank body, it is more and more used to build parts inside the tank body. [0003] Metal fuel tanks need to install valves, pipelines, pipe clamps and other parts to realize the functions of fuel storage, fuel delivery and fuel vapor control. These parts need to be respectively fixed inside the metal fuel tank, and the materials, shapes and The weights are all different, resulting in different ways of connecting each part to the metal fuel tank. Therefore, it is necessary to connect different types of fixing structures to the metal fuel tank in advance, resulting in the need for a variety of tooling and fixtures in the production process of the metal fuel tank. le...
