Abstract

The invention discloses an oil tank and oil pump matching structure, an oil pump, an oil tank and an automobile. The oil tank and oil pump matching structure involves the oil tank, an oil pump assembly, an oil pump flange, an oil pump oil storage barrel and an oil pump fixing seat, wherein the oil tank is used for storing fuel oil; the oil pump assembly is used to deliver the fuel oil to an engine; the oil pump flange is fixedly connected with the oil tank and is used for fixing the oil pump assembly; the oil pump oil storage barrel is connected with the oil pump flange through an oil pump guide rod; the oil pump fixing seat is fixedly connected with the oil tank and is used for fixing the oil pump oil storage barrel; and the oil pump fixing seat is matched with the oil pump oil storage barrel, so that when the oil pump oil storage barrel rotates in a first direction relative to the oil pump fixing seat, the oil pump oil storage barrel and the oil pump fixing seat are fastened, and when the oil pump oil storage barrel rotates in a second direction relative to the oil pump fixing seat, the oil pump oil storage barrel is loosened from the oil pump fixing seat. According to the oil tank and oil pump matching structure, the detachable property of the oil pump can be maintained while the strength and rigidity of the oil tank are enhanced.

Description

Technical field

[0001] The present invention relates to the field of automobiles, and in particular to a fuel tank and fuel pump matching structure, an oil pump, a fuel tank, and an automobile with such a fuel tank and fuel pump matching structure. Background technique

[0002] The internal combustion engine does not start during the normal operation of the PHEV, so the oil vapor in the fuel tank can not be consumed inside the fuel tank, and the regulations require that the oil vapor must not be discharged into the atmosphere, causing environmental pollution. Therefore, the accumulation of oil vapor causes excessive pressure inside the fuel tank , And vehicle fuel tanks are generally plastic fuel tanks with low stiffness and strength. If no special measures are taken, the fuel tank shell will rupture and leak oil due to excessive internal pressure. Therefore, components that enhance the stiffness of the fuel tank are needed to support the fuel tank shell. Withstand internal press...
