Problems solved by technology

In the prior art, the mold is used to extrude and connect the upper and lower surfaces of the plastic parison in the blow molding process, which is commonly known as the KISS-OFF structure. Poor performance; another kind of common technology is by arranging some supporting columns in the fuel tank, using the supporting columns to support the fuel tank, such as the supporting columns used in the prior art CN104477027A are metal rods, the metal rods are plastic coated, This kind of column containing metal parts is expensive to manufacture and needs anti-static treatment. The middle part of the column contains metal, which is stronger than the part connected at both ends, making the connecting part at both ends of the column prone to failure
In addition, the high metal density will add more weight to the hollow box
Both of the above two methods of supporting the fuel tank increase the strength of the fuel tank. However, when the fuel tank collides, the support columns in the prior art are strong and difficult to break, which will cause the surface of the fuel tank to be torn, causing the fuel tank to leak and cause danger.

Embodiment 1

[0022] Embodiment 1: see figure 1 , a support body connecting the upper and lower surfaces inside the fuel tank, the support body includes a connecting column 1, the upper and lower sides of the connecting column are provided with end faces 2, and the end faces 2 are covered with plastic, and the connecting column 1 is A notch 5 is provided, and the number of the connecting column 1 is at least one. In this technical solution, the number of connecting columns is set to two, and the overall shape is set to H shape, and the two connecting columns are connected by connecting rod 3, wherein the connecting rod is provided with a fixing hole 4, and the function of the fixing hole 4 is When lagging the end faces, the entire support is secured. When there are two connecting columns in the middle of the upper and lower ends of the support body, the connecting columns are solid, and the cross-sectional diameter of the end surface of the supporting column is smaller than that of the hol...

Embodiment 2

[0023] Example 2: see figure 1 , image 3 , Figure 4 , as an improvement of the present invention, the connecting column 1 is also set in one of I-shape, M-shape, and W-shape. The notch 5 is set to be V-shaped, U-shaped, semicircular or other irregular figures, and the notch is provided mainly to make the fuel tank not lose its strength, and the connecting column 1 is more likely to break when a collision occurs by utilizing the notch effect, Thereby avoiding the surface of the fuel tank from being torn and preventing the fuel tank from leaking; other structures and advantages are exactly the same as those in Embodiment 1.

Embodiment 3

[0024] Embodiment 3: see figure 1 , image 3 , Figure 4 , as an improvement of the present invention, the notch 5 is set on the left side and / or right side and / or middle of the connecting column. After a large number of experiments, it has been proved that the cracking effect is best when the notch is set in the middle of the connecting column. In addition, according to The height of different connecting columns, the size and shape of the gap all need to be adjusted. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a support for connecting an inner upper surface with an inner lower surface of an oil tank. The support comprises at least one connection column. An end face is arranged on each of the upper side and the lower side of each connection column, and is coated with plastic. A notch is formed in each connection column. The connection columns can be in the shape of I, H, M or W or in other shapes. The support has the advantages that the strength can be guaranteed, and the support can be broken easily during collision, so that surface tearing and leakage of the oil tank are avoided, and safety of the oil tank is guaranteed.

Description

technical field [0001] The invention relates to a support body, in particular to a support body connecting the upper and lower surfaces inside the fuel tank, and belongs to the technical field of fuel tank structural components. Background technique [0002] Because plastic fuel tanks have the advantages of light weight, corrosion resistance and higher product shape design freedom, most of the current automotive fuel tanks are practical plastic fuel tanks. Although plastic fuel tanks have many advantages, because the material used in plastic fuel tanks is HDPE, they have insufficient resistance to compression deformation, such as the resistance to deformation of conventional plastic fuel tanks under the effects of fuel gravity deformation and immersion aging . And in some special engineering fields, when it is necessary to maintain the high pressure inside the fuel tank, it needs to have the ability to withstand high pressure deformation, such as the fuel tank of plug-in hy...
