Problems solved by technology

[0002] At present, during the operation of the vehicle, there are the following situations: 1. During the climbing process, the vehicle body tilts, causing the fuel tank to tilt, so that the liquid level changes, and the oil cannot be sucked, resulting in insufficient engine power or flameout
2. When the vehicle is braking, the liquid in the fuel tank sloshes to produce inertial impact force and damage the components in the tank, and the vehicle consumes extra energy
3. When used for a long time, impurities and dirt will be deposited at the bottom of the fuel tank, which is easy to block the oil suction port
In order to solve the above problems, certain improvements have been made in the existing technology. For example, if an iron-welded anti-wave plate is installed in the fuel tank, the metal material will be affected by thermal expansion and contraction and corrosion, and the plate structure will crack and fall off.

Embodiment 1

[0026] Such as figure 1 , 2 3. The rotomolded integrated oil tank with oil retaining structure shown in 3 includes a fuel tank body 1 on which an oil inlet 2, an oil suction port 3 and an oil return port 4 are arranged; an oil retaining structure 5 is arranged in the tank , the oil retaining structure 5 has two facing protrusions 51 surrounding the oil suction pipe 6, the two facing protrusions 51 surround the oil suction pipe 6 to form an oil suction area, and between the two protrusions 51 An oil inlet passage 52 is set, and the protruding part 51 is a circular arc protruding from the bottom of the fuel tank after installation to the top of the fuel tank. The two ends of the arc protrusion are located in another arc protrusion, and the gap between the overlapping parts of the two arc protrusions constitutes the oil inlet passage 52, wherein the arc of the large radius arc faces the oil return pipe 7, so that the oil inlet passage 52 is on the side away from oil return pipe...

Embodiment 2

[0031] As a further optimized design of Embodiment 1, the bottom plate of the oil storage box below the oil return pipe 7 is set as an inclined plate, and the inclination direction is inclined from the side of the oil return pipe to the side of the oil retaining mechanism, and on the bottom plate of the oil storage box at the outlet of the corresponding oil return pipe An oil receiving groove 71 is provided. This structure can ensure that the return oil is quickly dispersed and flows to the oil retaining structure, and the oil receiving groove 71 can not only enhance the strength of the box body, but also withstand the oil spray from the oil return pipe.

[0032] As a further optimized design of Embodiment 1, a settling groove 53 is set on the bottom plate of the oil tank in the two facing protrusions 51, the oil suction port of the oil suction pipe 6 is located above the settling groove 53, and at the oil suction port of the oil suction pipe 6 A filter layer 61 is installed. ...

Embodiment 3

[0035] As a different design of Embodiment 1, the raised piece 51 can also be designed as one or a combination of V-shaped and U-shaped, as long as the designed two raised pieces 51 have a certain height, they can form a circle around each other. The oil storage space only needs to have an oil inlet channel 52 .

[0036] The purpose of the foregoing embodiments is all to achieve the following technical effects:

[0037] 1. The oil enters the oil suction area from the oil inlet channel of the oil gear structure. The oil inlet channel can block the entry of large foreign matter, and the small particles of impurities that enter are deposited in the sedimentation groove. The oil suction port is placed above the sedimentation groove to ensure oil absorption and impurities. separation;

[0038] 2. The oil retaining structure prevents the oil entering the oil retaining structure from flowing out easily. When there is less oil in the fuel tank or the vehicle is tilted, there is oil a...

Abstract

The invention discloses a rotational molding integrally-formed oil tank with an oil blocking structure. The rotational molding integrally-formed oil tank comprises an oil tank body, and an oil inlet, an oil suction pipe and an oil return pipe are arranged on the oil tank body; the oil blocking structure is arranged in the tank body and is provided with two opposite protruding pieces surrounding the outside of the oil suction pipe, the two opposite protruding pieces surround the oil suction pipe to form an oil suction area, an oil inlet channel is arranged between the two protruding pieces, and the protruding pieces are protruding structures from the bottom of the installed oil tank to the top of the oil tank. And the protruding structures have a set height. The oil inlet channel of the oil blocking structure prevents large foreign matters and small-particle impurities from precipitating in the precipitation groove, so that the separation of oil absorption and impurities is ensured; oil in the oil retaining structure cannot flow out easily, and stable operation of an engine is guaranteed when oil in the oil tank is less or a vehicle inclines; the oil blocking structure eliminates or reduces inertia impact force, reduces damage of oil to the box body and the oil suction pipe, and can achieve the 360-degree oil storage effect no matter which direction the vehicle body inclines towards.
