A grid-shaped fuel tank

Abstract

The application discloses a grid-shaped fuel tank, which belongs to the field of auto parts. The grid-shaped fuel tank includes: a fuel tank housing that encloses a cavity including a fuel chamber, and the fuel tank housing includes an upper upper housing area, a middle middle housing area, and a lower lower housing area; the middle grid rib structure is set in the cavity corresponding to the middle shell height area, and the middle grid rib structure divides the middle part of the cavity into several middle grid cavities, one of the middle grid cavities There is no communication between them in the radial direction, and the bottom end of the first group of middle mesh chambers included in the middle mesh chambers is provided with oil openings to communicate with each other to form the fuel chamber. The grid-shaped fuel tank does not need to be designed with a separate anti-surge partition, and can significantly reduce the fuel surge; in addition, it can prevent the tank from being deformed or cracked when it is impacted by an external force; in addition, the fuel flows in the lower shell area, Thereby greatly reducing the impact force of fuel flow and weakening the "surge" phenomenon of fuel.

Description

technical field [0001] The application relates to a grid-shaped fuel tank, which belongs to the field of auto parts. Background technique [0002] With the rapid development of the automobile industry and the improvement of automobile environmental protection requirements, the fuel tank is an important safety and regulatory part in automobile parts, and its structure optimization and performance improvement have become a problem that major automobile manufacturers are competing to discuss and solve. [0003] During the driving process of the vehicle, when encountering road bumps, starting and stopping, or turning, the fuel inside the fuel tank will shake and surge forward or backward, which will impact the fuel tank body, causing deformation of the fuel tank or making the fuel tank Cracks in the welded parts lead to oil leakage, which affects driving safety; in addition, the fuel surge will cause the center of gravity of the entire vehicle to shift, directly affecting drivin...

AI Technical Summary

Problems solved by technology

[0003] During the driving process of the vehicle, when encountering road bumps, starting and stopping, or turning, the fuel inside the fuel tank will shake and surge forward or backward, which will impact the fuel tank body, causing deformation of the fuel tank or making the fuel tank Cracks in the welded parts lead to oil leakage, which affects driving safety; in addition, the fuel surge will cause the center of gravity of the entire vehicle to shift, directly affecting driving safety, and even fuel spillage occurs; and the fuel surge hits the inner wall of the fuel tank, resulting The noise seriously reduces people's driving experience

[0004] At present, in order to reduce the impact force of the fuel inside the fuel tank, a partition is usually installed inside the fuel tank. In the prior art, the partition is usually welded to the wall of the fuel tank, and the middle part is opened to pass through the oil. However, this welding structure is easy to make the partition and the tank body Stress concentration in the welding seam of the car body, the surge of fuel will cause cracks at the welding position of the partition plate and the box body during the moving process of the car body, and the anti-surge phenomenon is not ideal
