Technical Field

The invention relates to the technical field of design and production of vehicle structural parts, in particular to an oil tank for a vehicle and a motorcycle.

Background

As an energy storage device of a vehicle, an oil tank plays an important role in guaranteeing the driving range of the vehicle. Because the oil tank is fixed on the vehicle, the liquid level in the oil tank is inevitably changed when the vehicle is accelerated and turned sharply, and particularly, when the oil level is low, the oil liquid can shake violently in the oil tank.

In order to avoid the phenomenon of suction of the oil pump, a downward recess is generally arranged at a local position of the bottom of the existing oil tank, so that an oil pool is formed at the bottom of the oil tank, and an oil suction port of the oil pump is arranged in the oil pool.

Although the oil tank with the concave bottom can avoid pumping air to a certain extent, the oil tank is formed by a local concave mode at the bottom of the oil tank, so that the shape of the bottom of the oil tank is irregular, the oil tank is difficult to arrange and install, the space at the position where the bottom of the oil tank is not concave is wasted, and the space utilization rate of the oil tank is not high.

Therefore, how to not only avoid pumping out of the oil tank, but also improve the convenience and space utilization rate of the oil tank arrangement is a technical problem that needs to be solved urgently by those skilled in the art at present.
