Problems solved by technology

In the prior art, in order to prevent the deformation of the fuel tank, a built-in support is usually used in the fuel tank, and the support is dissolved in the upper and lower surfaces of the fuel tank through the port with pockmarks, but this method is only applicable to the two-piece parison process, and the traditional fuel tank is passed It is made of one piece of parison, and the supporting parts cannot be placed in it. Although most of the existing fuel tank production processes adopt two-piece type, traditional fuel tanks still occupy a certain market. For traditional fuel tanks, there is currently no technology to prevent traditional fuel tanks from deforming. Therefore, There is an urgent need for a solution to this technical problem

Embodiment 1

[0018] Embodiment 1: see figure 1 , an anti-deformation support rod for a fuel tank, the support rod includes two connecting components 1 and a supporting column 2 passing through the two connecting components, the connecting component is set as a hollow body structure, and the connecting component is made of high-strength plastic with anti-corrosion The connection assembly includes a connecting post 3 and a connecting cap 4, wherein the connecting post 3 and the connecting cap 4 are integrally formed, and the connecting cap is stuck outside the fuel tank, and the diameter of the connecting post is smaller than that of the connecting cap .

Embodiment 2

[0019] Example 2: see figure 1 , as an improvement of the present invention, at least one connection assembly 1 is provided with a sealing ring 5, the cross section of the sealing ring is a circle with a diameter of 3mm, and the shape is a ring with a diameter of 31mm. The material is generally selected from FKM, and the purpose is to prevent Fuel seeps into the gap hole in the middle of the column, which is located in the middle of the upper and lower columns.

Embodiment 3

[0020] Embodiment 3: see figure 1 , figure 2 , As an improvement of the present invention, the support column 2 is set as a screw and nut combination structure, or other structural components that can be assembled and fixed are selected, and a multi-layer cover 7 is provided on the outside of the connection cap to prevent fuel from corroding the internal support column. .

Abstract

The invention relates to an anti-deformation fuel tank. The fuel tank comprises a fuel tank shell and a built-in assembly arranged in the fuel tank shell; the fuel tank shell comprises an upper shelland a lower shell; and the fuel tank further comprises a supporting rod, and the supporting rod penetrates through the whole fuel tank shell. According to the scheme, a connecting piece is placed in the fuel tank in the mode of outside the fuel tank, deformation of a traditional fuel tank under the pressure effect is prevented, the compressive performance of the traditional fuel tank is improved,and the service life of the fuel tank is prolonged.

Description

technical field [0001] The invention relates to a support rod and an anti-deformation fuel tank, belonging to the technical field of fuel tank structural components. Background technique [0002] The hollow tank of the car contains fuel. Under the influence of the temperature inside and outside the car and the driving vibration, there will be a certain pressure in the hollow tank, which will cause the hollow tank to deform. In some sealed fuel systems, the pressure on the hollow tank will The deformation effect is more pronounced. In the prior art, in order to prevent the deformation of the fuel tank, a built-in support is usually used in the fuel tank, and the support is dissolved in the upper and lower surfaces of the fuel tank through the port with pockmarks, but this method is only applicable to the two-piece parison process, and the traditional fuel tank is passed It is made of one piece of parison, and the supporting parts cannot be placed in it. Although most of the ...
