Description

Oil pan for engine Technical Field The utility model relates to the technical field of engines, in particular to an oil pan for an engine. Background The oil pan is located in the lower part of the automobile engine. Its main function is to close the crankcase and prevent sundries from entering the oil tank. At present, most engine oil bottom cases basically adopt conventional design, are manufactured by adopting a stamping process (steel plate stamping forming), and the steel plate stamping structure is not easy to crack (compared with cast aluminum) when being slightly bumped, so that the engine oil bottom cases are suitable for complex road conditions, but the stamping oil bottom cases are large in general weight, high in manufacturing cost, obvious in noise, low in machining dimensional precision and rough in appearance. Therefore, there is a lack of an easy-to-form, low-noise, lightweight, low-cost engine sump in the prior art. Disclosure of utility model The embodiment of the utility model aims to provide an engine oil pan which is easy to form, low in noise, light in weight and low in cost, so that the defects of the prior art are overcome. The specific technical scheme is as follows: an oil pan for an engine comprises a shell, an oil suction pipe and a horn; the shell comprises a deep groove area and a shallow groove area; The deep groove area and the mounting surface of the shallow groove area are positioned on the same plane, the bottom surface of the deep groove area is connected with the bottom surface of the shallow groove area through an inclined plane, and the mounting surface is opposite to the bottom surface of the deep groove area; an oil drain hole is formed in the bottom surface of the deep groove area, and an oil drain insert is fixed in the oil drain hole; The mounting surface is provided with a first oil suction port and a second oil suction port, the first oil suction port is positioned in the deep groove area, the second oil suction port is positioned in the shallow groove area, and the cross sections of the first oil suction port and the second oil suction port are elliptical; the side surface of the deep groove area is provided with a first bulge, and the side surface of the shallow groove area is provided with a second bulge; The other side face of the deep groove area is provided with a dipstick hole, two sides of the dipstick hole are provided with insert holes, and metal bolts are arranged in the insert holes; The oil suction pipe is in a closed flat tubular shape, one end of the oil suction pipe is fixedly connected with the first oil suction port, the other end of the oil suction pipe is fixedly connected and communicated with one end of the horn, and the other end of the horn is in a preset distance with the bottom surface of the deep groove area. Optionally, the other end of the oil suction pipe is welded and connected with one end of the horn. Optionally, a filter screen is fixed between the oil suction pipe and the horn. Optionally, one end of the oil suction pipe is welded with the first oil suction port.

Optionally, a through hole is formed in the mounting surface, and a metal insert is fixed in the through hole. Optionally, the metal insert is embedded in the through hole, or is fixed in the through hole by interference fit or adhesion. Optionally, a reinforcing rib is arranged on the outer surface of the shell. Optionally, the housing, the oil suction tube and the horn are all injection molded. Compared with the prior art, the shell, the oil suction pipe and the horn piece of the oil pan for the engine have the advantages of simple structure, easy molding, low design and manufacturing cost and simple assembly process.
