LATTICED FUEL TANK

Disclosed is a grid-shaped fuel tank, which belongs to the field of vehicle parts. The grid-shaped fuel tank includes a fuel tank shell, wherein the fuel tank shell encloses a cavity comprising a fuel cavity, and the fuel tank shell comprises an upper shell area in an upper portion, a middle shell area in a middle portion and a lower shell area in a lower portion; the cavity is internally provided with a middle grid rib structure corresponding to a height area of a middle shell, the middle grid rib structure partitions a middle portion of the cavity into a plurality of middle grid cavities, the middle grid cavities do not communicate in a radial direction, and a bottom end of a first middle grid cavity group comprised in the middle grid cavities is provided with fuel passing ports for mutual communication to form the fuel cavity. The grid-shaped fuel tank does not need a separate anti-surge diaphragm, and the surge phenomenon of fuel can be significantly reduced; in addition, a tank body can be prevented from deformation or cracking when being impacted by external forces; and in addition, the fuel flows in the lower shell area, which greatly reduces the impact caused by the flow of the fuel and weakens the "surge" phenomenon of the fuel.
