Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like figure 1 As shown, a novel fuel tank anti-wave plate structure provided by the present invention includes anti-wave horizontal plates 2 arranged along the length direction of the fuel tank, several anti-wave vertical plates 1 arranged oppositely along the height direction of the fuel tank, and several anti-wave vertical plates. The plates 1 are connected to each other through the anti-wave horizontal plate 2 and become a whole, and the anti-wave horizontal plate 2 is provided with a plurality of first through holes 21;

[0024] Since the anti-wave horizontal plate 2 and several anti-wave vertical plates 1 are arranged oppositely, when the fuel level in the fue...

Abstract

The invention discloses a novel fuel tank wave-proof plate structure, which comprises a wave-proof transverse plate arranged along the length direction of the fuel tank, and a plurality of wave-proofvertical plates oppositely arranged along the height direction of the fuel tank, wherein the plurality of wave-proof vertical plates are mutually connected through the wave-proof transverse plate to form a whole body, the wave-proof transverse plate is provided with a plurality of first through holes. According to the wave-proof plate structure, when the liquid level of the fuel oil is lower thanthe wave-proof transverse plate, the shaking of the fuel oil is blocked by the wave-proof transverse plate, the wave-proof vertical plates can also effectively prevent the shaking of the fuel oil, andthe shaking fuel oil cannot impact the upper surface of the fuel tank; when the liquid level of the fuel oil is higher than the wave-proof transverse plate, the wave-proof transverse plate divides the fuel oil in the fuel tank into an upper part and lower part which are relatively independent, the wave-proof transverse plate and the wave-proof vertical plates can effectively reduce the mutual influence between the fuel oil of the two parts, the shaking energy of the fuel oil above the wave-proof transverse plate is small, the shaking fuel does not form effective impact on the upper surface ofthe fuel tank, and the shaking noise which can be sensed by passengers cannot be generated in the fuel tank. The invention also discloses a fuel tank.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a novel fuel tank anti-wave plate structure and a fuel tank comprising the novel fuel tank anti-wave plate structure. Background technique [0002] With the continuous improvement of the NVH level of the vehicle, under certain working conditions, the fuel sloshing noise in the fuel tank will become extremely prominent. The noise of fuel sloshing will cause customers to complain about the product, worry about the quality of the product, and even market complaints about the product in serious cases (similar incidents have occurred in Changan CS75 / Geely Boyue). [0003] The design of the anti-wave plate structure inside the fuel tank is particularly important to reduce or even avoid fuel sloshing noise. An excellent anti-wave plate structure can effectively solve the problem of fuel slosh noise, and is versatile (different fuel tanks can be used). However, at present, there is ...
