Description

Technical Field

[0001] The utility model relates to the technical field of engine accessories, in particular to an oil filter pan for an automobile. Background Art

[0002] The oil pan is the lower half of the crankcase, also known as the lower crankcase. Its function is to seal the crankcase as the outer shell of the oil storage tank to prevent impurities from entering, and to collect and store the lubricating oil flowing back from the friction surfaces of the diesel engine, dissipate some of the heat, and prevent the lubricating oil from oxidizing. The oil pan is located at the bottom of the engine: it can be disassembled and the crankcase seal is used as the outer shell of the oil storage tank. The oil pan is mostly stamped from thin steel plates, and those with more complex shapes are generally cast in cast iron or aluminum alloy.

[0003] For example, the authorization announcement number "CN219733484U" is named a filter oil pan. Although a drain port is set at the bottom of the oil pan, the oil can be directly discharged without disassembling the oil pan after the bottom cover plate on one side of the drain port is opened, which makes the cleaning operation inside the oil pan more convenient and efficient. However, the existing filter oil pan adopts a filter plate that slides into the oil pan to reduce the dirt and impurities in the oil inside the oil pan. However, the filter plate adopts a plurality of small holes to achieve the effect of filtering the dirt through the oil. However, as the car starts to work, the oil with dirt will flow into the filter oil pan continuously, so a large amount of dirt will accumulate on the top of the filter plate, which makes the holes of the filter plate easily blocked, resulting in excessive accumulation of dirt, and the oil entering the filter oil pan is also difficult to flow to the lower oil pan through the blocked holes, which will cause the oil above the filter plate to gradually accumulate, and eventually cause the problem of oil backflow or leakage, which directly affects the use effect of the filter oil pan.

[0004] At the same time, the existing filter oil pan is closed by using a bottom cover plate of the sewage outlet that is clamped and fixed at the bottom end. The clamped bottom cover plate is not particularly firmly fixed, and small gaps are prone to appear at the connection around the bottom cover plate and the sewage outlet. The oil pan stores oil with good lubrication and fluidity. As the amount of stored oil increases, the pressure on the bottom cover plate below will gradually increase, which makes it easy for a part of the oil to be squeezed out along the gaps around the bottom cover plate, causing oil leakage in the oil pan, which in turn affects the poor sealing performance of the filter oil pan. Utility Model Content

[0005] The utility model aims to solve the problems of poor use effect and poor sealing performance of a clean energy conversion device, and proposes an oil filter pan for an automobile.

The top of the multiple dredging columns 46 corresponds to the position of the multiple through holes 54. When the oil enters the inside of the oil pan body 1, the filter plate body 53 plays a role in filtering the oil and dirt, so that the dirt will gradually accumulate on the filter plate body 53. After the dirt accumulates for a certain period of time, the power supply is connected to start the oil cylinder 42, and the multiple oil cylinders 42 will push the multiple push rods 43 upward. When the push rod 43 moves upward, the push rod 43 will be stably and accurately pushed to the inside of the through hole 54 inside the filter plate body 53 under the transmission cooperation of the second connecting rod 44 and the first connecting rod 45 on both sides, and the dirt blocking the inside of the through hole 54 will be dredged to avoid blockage;
