Description

Technical Field

[0001] This utility model relates to the field of engine technology, and in particular to an oil pan for an engine. Background Technology

[0002] The oil pan is located at the bottom of the car engine. Its main function is to close the crankcase and prevent foreign matter from entering the oil tank.

[0003] Most engine oil pans currently use a conventional design and are manufactured using a stamping process (stamping of steel plates). Stamped steel plates are less prone to cracking when subjected to minor impacts (compared to cast aluminum), making them suitable for complex road conditions. However, stamped oil pans are usually heavier, have higher manufacturing costs, generate noticeable noise, and have lower dimensional accuracy and a rougher appearance.

[0004] Therefore, there is a lack of an engine oil pan that is easy to mold, low in noise, lightweight, and low in cost in the existing technology. Utility Model Content

The other end of the horn component 3 has a preset distance from the bottom surface 111 of the deep groove area 11.

[0045] It can be understood that mounting surface 101 is the sealing surface at the top of the oil pan.

[0046] It should be noted that the oil drain insert 4 can be pre-embedded in the position of the oil drain hole 103 and directly embedded in it during injection molding, or it can be achieved by interference fit or bonding between the oil drain insert 4 and the oil drain hole 103. The housing 1 is connected to the oil drain plug through the oil drain insert 4 to ensure the discharge of the oil in the housing 1. The oil drain insert 4 is used to ensure the connection strength.

One end face of the second oil suction port 123 is flush with the mounting surface 101, and the other end is located inside the end side of the shallow groove area 12 and is fixedly connected to one end of the oil suction pipe 2. A welding rib can be provided on the end face of the second oil suction port 123 located inside the end side of the shallow groove area 12, and a welding surface is provided on one end face of the oil suction pipe 2. The welding rib of the second oil suction port 123 and the welding surface of the oil suction pipe 2 are fixedly connected by welding.

[0049] The other end of the oil suction pipe 2 is welded to and connected to one end of the horn component 3; for example, the other end of the oil suction pipe 2 can be provided with a welding rib, and one end of the horn component 3 is designed with a welding surface. The welding rib of the oil suction pipe 2 and the welding surface of the horn component 3 are fixedly connected and connected by welding.

[0050] Furthermore, in order to effectively filter impurities in the engine oil, a filter screen 5 is fixed between the oil suction pipe 2 and the horn component 3. In practical applications, the filter screen 5 can be placed on the welding surface of the horn component 3 first, and then the oil suction pipe 2 can be fixedly connected to the horn component 3 and the filter screen 5 by welding.

[0051] Specifically, in order to ensure the sealing of the oil pan, the mounting surface 101 of the deep groove area 11 and the shallow groove area 12 has a sealing groove 104, and a rubber sealing gasket 6 is installed in the sealing groove 104.

[0052] Optionally, in order to improve the overall installation strength of the oil pan, a through hole 105 is provided on the mounting surface 101, and a metal insert 7 is fixed in the through hole 105.

[0053] Specifically, in order to ensure that the metal insert 7 can be stably fixed in the through hole 105, the metal insert 7 can be embedded in the through hole 105, or fixed in the through hole 105 by interference fit or bonding.

[0054] Optionally, in this embodiment, a heater hole 106 is also provided on the side 112 of the deep groove area 11. An oil heating device 8 is installed in the heater hole 106. The oil heating device 8 can be used to heat the oil to ensure the lubricity of the oil.

Specifically, the reinforcing ribs 107 are distributed in a crisscross pattern, with a center-to-center distance of 8-10 mm and a thickness of 2 mm in the length direction, and a center-to-center distance of 35-45 mm and a thickness of 2 mm in the width direction.

[0056] Optionally, in this embodiment, the oil pan housing 1, the oil suction pipe 2, and the horn component 3 are all injection molded.

[0057] During injection molding, a through hole 105 is provided on the mounting surface 101. The metal insert 7 is pre-placed in the position of the through hole 105 in the mold and directly embedded in the through hole 105 during injection molding. Then, the housing 1 is bolted to the engine through the through hole 105, and the embedded metal insert 7 ensures the connection strength. To ensure the sealing of the connection between the housing 1 and the engine, a rubber sealing gasket 6 is provided in the rectangular sealing groove 104 on the sealing surface. The elasticity of the rubber sealing gasket 6 ensures the sealing between the housing 1 and the engine.

[0058] Because the housing 1, oil suction pipe 2, and horn component 3 are injection molded separately, and their simple structure facilitates assembly, the overall design and manufacturing costs are low. A rubber gasket replaces the conventional paper-based gasket, utilizing the elasticity of rubber to ensure airtightness between the housing and the cylinder block. Due to the excellent wear resistance of rubber, the rubber gasket can be reused after the oil pan is disassembled. The oil pan is made of fiber-reinforced thermoplastic composite material, which reduces noise pollution during vehicle operation. The oil suction pipe is equipped with a filter device to effectively filter impurities in the engine oil, ensuring normal engine operation. The reinforcing rib design ensures the impact resistance and high strength of the housing.
