[0028] In the traditional fuel tank structure, the filter is usually arranged at the fuel filling port for filtering the impurities that can enter the fuel tank during the fuel filling process, preventing the impurities from entering the oil circuit system, thereby protecting the normal operation of the fuel pump and the engine. However, it is found in actual use that the filter at the fuel filling port is limited in size, and has a small filtering area, which can easily cause the fuel filling flow rate to decrease, and even cause the backflow phenomenon during the fuel filling process, resulting in the early jump of the fuel gun, affecting the fuel filling efficiency. Moreover, the filter is easy to be blocked, and has a high replacement frequency.
[0029] Therefore, the embodiments of the utility model provide a fuel tank assembly and a vehicle, which set the filter structure in the first tank body, and there is no part in the fuel filling pipe that affects the smoothness of filling, thereby reducing the adverse effect on the fuel filling flow rate, improving the fuel filling efficiency, and preventing the early jump of the fuel gun caused by the backflow during fuel filling. At the same time, compared with setting the filter structure in the fuel filling pipe, the first tank body has a larger space, and the volume of the filter structure can be designed to be larger, thereby increasing the filtering area and prolonging the cleaning period of the filter structure, meeting the needs of long maintenance period of users, and improving customer satisfaction.
[0030] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the drawings.

Meanwhile, compared with arranging the filter structure 300 in the fuel filling pipe 600, the space of the first tank body 100 is larger, and the volume of the filter structure 300 can be designed to be larger, so that the filtering area is increased, the cleaning period of the filter structure 300 is prolonged, the demand of the user for a long maintenance period is met, and the customer satisfaction is improved.

In this process, since the fuel can flow from each position around the filter core to the clean cavity, the adverse effect of the filter core on the fuel flow rate can be reduced, and the fuel filling efficiency is improved. In addition, after the second tank body 200 is filled with clean fuel, the fuel stored in the first tank body 100 can be preliminarily filtered, and as the fuel in the second tank body 200 is consumed, the fuel preliminarily filtered in the first tank body 100 flows into the second tank body 200 after being filtered by the filter core, so that the filtering effect of the fuel can be improved.
