Technical Field

The invention relates to a breakwater, in particular to a multifunctional oil tank breakwater, and belongs to the technical field of automobile oil tank structural components.

Background

With the continuous increase of automobile holding capacity in China every year, the problem of automobile exhaust pollution is increasingly serious, so that development of new energy vehicles and promotion of strategic transformation of the traditional automobile industry are widely recognized, and the automobiles have the most industrialization and market prospects in a mixed manner. Due to the reduction of noise levels of systems such as a hybrid automobile engine, air intake and exhaust and the like, the problem of fuel shaking noise inside a fuel tank is increasingly prominent. In order to solve the noise problem of the fuel tank, it is usually necessary to add a breakwater inside the hybrid high-pressure fuel tank to reduce the impact of the fuel on the fuel tank wall, but in the conventional welding process of the breakwater, as shown in patent 201210202257.6, it is necessary to add additional auxiliary equipment to put the breakwater into the tank during the blow molding process, and the breakwater is welded inside the fuel tank, and then it is necessary to consider the Z-direction axial stretching and squeezing caused by the tank shrinkage deformation (generally up to 5%) of the breakwater, and the conventional fuel tank has the following problems:

1) many fuel tanks do not have breakwaters;

2) the strip-shaped convex structure formed on the surface of the fuel tank is adopted by part of the fuel tank to prevent the fuel from moving in the fuel tank to form a wave-proof structure, the rated volume of the fuel tank is reduced due to the structure, the difficulty of a blow molding process is increased, and a thin-wall-thickness area is easily formed due to severe stretching of a parison;

3) a corrugated plate is placed on a part of the fuel tank in a punching and welding mode, holes need to be punched on the surface of the fuel tank, the discharge of the fuel tank is increased, and the fuel tank passes the regulation inspection;

4) the breakwater is placed in a part of fuel tanks in an internal welding mode, special auxiliary equipment needs to be manufactured, and the forming process of the fuel tanks has high requirements.

5) The breakwater formed in the blow molding process of the oil tank reduces the rated volume of the oil tank, increases the difficulty of the blow molding process, and easily causes the wall thickness not to meet the index requirement;

the conventional breakwaters have the following problems:

the punching and welding of the breakwater increases the subsequent process, and due to the existence of the punching and welding process, the emission of hydrocarbon is increased easily, the requirements of regulations are not met, and the environment is polluted; the breakwater welded inside adds special auxiliary equipment and increases certain cost; the novel wave-proof plate structure and the mounting method introduced by the patent can effectively solve the problems and efficiently achieve the purpose of reducing noise of the fuel tank.
