Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, and in particular to a wave-proof and noise-reducing plastic fuel tank. Background Technology

[0002] A plastic fuel tank is a component used to store automotive fuel and is made of materials such as resin plastic.

[0003] For example, CN219007586U discloses a multifunctional plastic fuel tank, including a main fuel tank, an auxiliary fuel tank and a urea tank. The main fuel tank, the urea tank and the auxiliary fuel tank are fixed together in sequence. It also includes a fuel coarse filter. The main fuel tank has a coarse filter mounting hole on its outer side. The fuel coarse filter is fixed to the coarse filter mounting hole by bolts.

[0004] However, in the current technology, during vehicle operation, especially when accelerating, decelerating, turning, or driving on bumpy roads, the fuel will shake violently in the fuel tank. This will not only cause inaccurate readings from the fuel level sensor, but also cause the fuel to mix fully with air, easily generating air bubbles. These air bubbles will enter the fuel system and cause vapor lock. Vapor lock will hinder the normal flow of fuel, resulting in insufficient fuel supply to the engine, leading to problems such as reduced power, poor acceleration, or even stalling. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where fuel shakes violently inside the fuel tank, which not only leads to inaccurate readings from the fuel level sensor but also causes the fuel to mix fully with air, easily generating bubbles. Therefore, this invention proposes a wave-proof and noise-reducing plastic fuel tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wave-proof and noise-reducing plastic fuel tank, comprising a fuel tank body, a trapezoidal protrusion fixedly installed on the inner wall of the fuel tank body, a first baffle slidably connected to one side of the protrusion, a vertical plate perpendicular to itself fixedly connected to the lower surface of the first baffle, a rectangular through hole opened inside the vertical plate, a spoiler rotatably installed on the side wall of the rectangular through hole, and a second baffle fixedly connected to the bottom of the vertical plate.

[0007] Preferably, a partition ring is fixedly installed in the middle section inside the fuel tank body, and the partition ring divides the fuel tank body into upper and lower parts.

[0008] Preferably, an inclined plate facing downwards is fixedly installed on the inner wall of the lower part of the fuel tank body.

[0009] Preferably, the top of the fuel tank body is provided with a first recessed groove.

[0010] Preferably, a second recessed groove is provided on the waist of the main body of the fuel tank.

[0011] Preferably, the first baffle is located in the upper half of the oil tank body, and the second baffle is located in the waist of the oil tank body.

[0012] Preferably, the first baffle, the vertical plate and the spoiler are I-shaped structures.

[0013] Compared with the prior art, the utility model has the advantages and positive effects that:

[0014] 1、The first baffle can cover the liquid level of the fuel oil to prevent the generation of bubbles in the process of shaking, the vertical plate and the second baffle are located below the first baffle, and the vertical plate and the second baffle form a blocking structure for preventing the fuel oil from shaking greatly.

[0015] 2、The first recessed groove and the second recessed groove are arranged, and the protruding block on the inner wall of the oil tank body is arranged, so that the fuel oil is unevenly distributed in the oil tank body, and in the process of shaking, the flow path of the fuel oil is irregular, and fuel oil in different directions collides and cancels each other in the process of flowing.

[0023] The middle section in tank main body 1 is fixedly installed with partition ring 4, and tank main body 1 is divided into two parts by partition ring 4, first baffle 6 is located in the upper half of tank main body 1, and second baffle 10 is located in the waist of tank main body 1, and first baffle 6, vertical plate 7 and spoiler 9 are I-shaped structure.

[0024] The inside space of tank main body 1 is divided into two parts by partition ring 4, in the case where tank is filled with fuel, first baffle 6 will float on the liquid surface of fuel, when vehicle runs and causes fuel to shake, can prevent the liquid surface of fuel from generating air bubble due to collision, and in the process of fuel shaking, will constantly contact with vertical plate 7, and vertical plate 7 will reduce the shaking amplitude of fuel, and reduce the probability of air mixing.

[0025] Rectangular through-hole 11 is arranged in vertical plate 7 to ensure that fuel does not appear partition, and spoiler 9 that can be pushed by fuel is rotatably installed on the inner side wall of rectangular through-hole 11, in the process of fuel shaking, will constantly push spoiler 9, since spoiler 9 is located on the axis of tank main body 1, therefore, in the process of rotation, will drive other parts of fuel, and the fuel driven is used to impact the fuel that is shaking, to achieve the purpose of preventing fuel from shaking in a large range.
