Description

Technical Field

[0001] This utility model relates to the field of oil pans, specifically to a novel leak-proof engine oil pan. Background Technology

[0002] The engine oil pan, also known as the lower crankcase, is a removable, sealed housing at the bottom of a car engine. It is a critical component of the lubrication system, primarily responsible for sealing the crankcase, storing lubricating oil, and preventing impurities from entering. Excessive impurities in the engine oil pan significantly increase the risk and likelihood of oil leaks. Hard particles in the oil act like tiny abrasives. As the oil circulates within the engine, flowing past various oil seals, gaskets, and sealing surfaces, these hard particles repeatedly scrape and grind against the seal surfaces and mating surfaces. This can lead to premature aging, hardening, cracking, or groove formation in the seals. Simultaneously, the mating metal surfaces may also be scratched, compromising their smoothness. Worn seals and scratched mating surfaces cannot effectively seal the oil, causing or exacerbating oil leaks.

[0003] Therefore, in order to solve the above-mentioned problems, a new type of leak-proof engine oil pan is proposed. Utility Model Content

[0004] This invention addresses the problems mentioned above by designing a novel leak-proof engine oil pan. This device filters the oil before circulation, causing impurities to settle on the filter residue section, reducing impurities in the circulating oil and preventing oil leakage caused by subsequent wear on the components.

[0005] To achieve the above objectives, this utility model provides a novel leak-proof engine oil pan, comprising: an outer shell, a filter section, a drain section, a baffle plate, and an oil drain port. One end of the inner wall of the outer shell is provided with a gentle slope, and the filter section is located at the lower part of the gentle slope. The drain section is connected to the end of the filter section away from the gentle slope. The filter section is horizontally positioned. The end of the drain section away from the filter section is connected to the bottom of the inner wall of the outer shell. The oil drain port is located at the bottom of the outer shell. The baffle plate is fixedly connected to the inner wall of the outer shell and is located on the side of the drain section away from the filter section.

[0006] In this way, the oil flows down a gentle slope and passes through the filter residue section. Large particles of impurities are blocked by the filter residue section, which is also detachable and can be cleaned regularly.

[0007] Furthermore, the filter cake section includes: a bottom plate, protrusions, side baffles, and a support device. A plurality of protrusions are fixedly provided on the upper surface of the bottom plate, and a side baffle is fixedly provided on the lower part of the bottom plate. A limiting plate is provided on the side of the slope and the drainage section near the bottom plate. The bottom plate is supported on the upper part of the support device, and the lower part of the support device is detachably connected to the side of the limiting plate.

[0008] Furthermore, the support device includes: a support plate, a connecting rod, and an insert plate. The upper and lower ends of the connecting rod are respectively fixedly connected to the support plate and the insert plate. The limiting plate has a hole for the insert plate to be inserted into, and the insert plate is inserted into the side of the limiting plate.

[0009] Furthermore, the support device also includes a positioning cylinder, which is fixedly connected to the side baffle, and the connecting rod is placed on the side of the positioning cylinder and fixedly connected to the positioning cylinder by bolts.

[0010] Furthermore, the support device also includes a support platform, which is a right-angled structure and is fixedly connected to the limiting plate, with the insert plate placed on the support platform.

[0011] In this way, the support plate, connecting rod, and insert plate form a fixed support to hold the bottom plate. At the same time, the positioning cylinder limits and fixes the position of the connecting rod. At the bottom, the support platform fixed to the limiting plate lifts the insert plate, further improving the support effect.

[0012] Furthermore, the drainage section includes an arc-shaped flow channel and an arc-shaped top. The surface of the drainage section is provided with a plurality of parallel arc-shaped flow channels, and an arc-shaped top is provided between adjacent arc-shaped flow channels.

[0013] Furthermore, the baffle plate includes: a main board, a sub-board, and through holes. The two ends of the main board are fixedly connected to the inner wall of the outer casing. Both the main board and the sub-board are provided with a plurality of through holes. The sub-board is inserted into the main board through the through holes.

[0014] In summary, this utility model has the following advantages and beneficial technical effects: 1. This utility model provides a novel leak-proof engine oil pan that can coarsely filter impurities in the oil, preventing large impurities from entering the oil circulation or causing blockage at the return oil pipe after filtration. 2. The filter part of the new leak-proof engine oil pan of this utility model can be disassembled and can be cleaned regularly. Attached Figure Description
