The power system of the hybrid electric vehicle is formed by combining an internal combustion engine and a battery, when the battery is used, the oil pump stops working, and gasoline is volatilized all the time, so that the vapor pressure of the fuel tank generated in the fuel tank is far higher than that of the fuel tank of the traditional vehicle. The internal pressure of the fuel tank of the traditional automobile is generally between 6kpa and 10kpa, and the internal pressure of the hybrid fuel tank is between 35kpa and 45kpa, so that the hybrid fuel tank needs to have higher rigidity requirement than the traditional fuel tank. Because of the limitation of the mechanical properties of the materials of the plastic fuel tank, a certain supporting structure is often required to be added in the fuel tank, so that the requirement of high rigidity of the fuel tank of the hybrid electric vehicle can be met.
The existing supporting structure often utilizes single solid plastic and diabolo-type plastic to connect the top and bottom surfaces inside the fuel tank, thereby improving the structural rigidity of the fuel tank. The rigid connection structure can obviously improve the rigidity of the fuel tank, and because the top surface and the bottom surface of the fuel tank are structurally and rigidly connected, when the fuel tank deforms under the action of internal pressure, the internal rigid support structure of the fuel tank bears additional bending load generated by the deformation asymmetry of the fuel tank body besides bearing the axial load generated by the pressure in the fuel tank, and the additional bending load can generate local larger stress deformation on the edge of the connecting end surface of the rigid support structure and the fuel tank, so that the connecting end surface of the rigid support structure is torn and fails under the condition that the axial strength of the rigid support structure is not fully utilized.
