[0029] In a typical embodiment of the present application, a plastic fuel tank is provided, such as Figure 1-2 As shown, it includes a box body, which is made of plastic material. A plurality of reinforcing ribs 1 are arranged on the side and plane of the box body to enhance the strength of the box body. In this way, the weight of the box body is relatively light while ensuring the strength of the fuel tank.

[0030] A sinking cavity 6 is provided at the bottom of the box body, which can be sunk into the cavity of the installation platform to facilitate positioning and installation, and can effectively protect the box body. At the same time, the center of gravity of the box body is lower, which can improve stability. One end of the side of the box body extends to the other side away from the box body to form an extension cavity 7, which increases the volume of the fuel tank. One side of the box body is processed from bottom to top to form a multi-level step 2 that can be stepped on. It has a stepped structure. Embedded nuts 3 are provided on the steps 2 for installing protective plates. In higher vehicles such as loaders, operators can step on them to climb up, which is convenient for maintenance and repair. At the same time, the overall volume of the fuel tank is reduced, which is beneficial to improving the performance of the entire vehicle. Figure 1 As shown, in this embodiment, the step is processed into three layers, and except for the bottom layer step, reinforcing ribs 1 are provided on the surfaces of the second and third layers of the step.

[0031] Specifically, the plastic box body is made by rotational molding, and the reinforcing ribs used to increase the strength are convex ribs, which can reduce dirt accumulation and facilitate cleaning.

[0032] like Figure 1 , 2 As shown, a fuel pump interface 4 is provided at one end of the side of the box body away from the extension cavity 7, which is used to connect the fuel pump. At the same time, a detachable plug 5 is provided on the fuel pump interface 4, and the plug 5 is installed on the fuel pump interface 4 through a threaded connection, which is convenient for disassembly. When the box body is not connected to the fuel pump, the plug ensures the sealing of the box body.

[0033] The top of the box body is provided with an oil level sensor installation port 14, which is convenient for installing the oil level sensor. The top of the box body is provided with a fuel tank cover 13, which can facilitate fuel filling while ensuring the sealing of the box body.

[0034] like Figure 2 As shown, the bottom of one side of the box is also provided with an oil outlet 10, an oil return port 11 and a water drain port 12. At the same time, in order to facilitate installation and positioning, concave cavities and reserved installation holes 8 are processed on the outer sides of the left and right sides of the box respectively. The concave cavities are provided with multiple parallel lines up and down to limit the position when installing the oil tank. Figure 1 As shown, a groove-shaped fixed step 9 is provided on the other side of the box body away from the side where the concave cavity is located, and on the step on the top of the box body near the installation port of the oil level sensor. The fixed step is used to fix the pressure plate when the fuel tank is installed to facilitate installation. Among them, a reserved installation hole 8 is provided at the fixed step 9 on the side of the box body to facilitate positioning when the fuel tank is installed.

[0035] Embodiment 2

[0036] In another embodiment of the present application, a vehicle is provided, including a fuel tank.
