Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an integrated oil pan baffle structure. Background Art

[0002] The oil pan is the lower component of the crankcase. Its main function is to seal the crankcase and act as a storage container for the lubricating oil to prevent the intrusion of external impurities. At the same time, it collects and stores the lubricating oil, dissipates some heat, and prevents the lubricating oil from oxidizing.

[0003] At present, the oil pan is equipped with an oil pan baffle, and an oil filter is installed on the oil pan baffle. The main function of the oil pan baffle is to prevent the oil in the oil pan from splashing violently due to vibration when the vehicle is running. The oil filter is connected to the engine, and the lubricating oil in the engine first flows into the oil pan, and then the oil pump is connected to the oil filter to ensure that the lubricating oil is finely filtered by the filter before being re-delivered to the engine, realizing the effective recycling of the lubricating oil.

[0004] The current oil filter is assembled from two semicircular parts through a welding process, and two sets of molds are required for molding before welding. After manufacturing, it is connected to the oil pan baffle with bolts and other fixings. The single mold for the oil pan baffle plus the two sets of molds for the oil filter significantly increase the development cost of the oil pan baffle structure and the production cycle is long. This design and production method not only increases costs, but also prolongs product development time. In addition, the lubricating oil mixed with impurities flowing out of the engine is scattered in the oil pan, which may affect the effective extraction of lubricating oil by the oil pump and reduce system efficiency.

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figures 1 to 5As shown, an integrated oil pan baffle structure of the present scheme is connected between the engine and the oil pan, and is used for filtering and collecting lubricating oil. The oil pan baffle structure includes: a baffle body 1, which has a first mounting surface 2 facing the engine side and a second mounting surface 3 facing the oil pan side, and the first mounting surface 2 and the second mounting surface 3 are arranged opposite to each other; a lower shell body 4, which is connected to the second mounting surface 3, the lower shell body 4 has an extension portion 5 facing the oil pan, an oil inlet channel 6 is arranged in the extension portion 5, and a filtering space is formed between the lower shell body 4 and the second mounting surface 3, an oil outlet 17 is arranged on the baffle body 1, the oil outlet 17, the filtering space and the oil inlet channel 6 are connected in sequence, and the filtering space is used to filter the lubricating oil in the oil pan; a return oil pipe 7, which is connected to the second mounting surface 3, and the return oil pipe 7 is used to connect to the engine to receive the lubricating oil flowing out of the engine.

[0026] The baffle body 1 is connected to the oil pan (not shown in the figure), the extension 5 of the lower shell 4 is inserted into the lubricating oil in the oil pan, and the oil pump (not shown in the figure) is connected to the oil outlet 17. When working, the oil pump extracts the lubricating oil in the oil pan by forming a negative pressure in the oil inlet channel 6. When the lubricating oil flows through the filter space, it first passes through the filter space and then flows into the engine from the oil outlet 17. The lubricating oil in the engine flows back to the oil pan through the return oil pipe 7. In this scheme, the end surface of the baffle body 1 away from the engine side and the lower shell 4 form a filter space together, which is used to reduce the manufacturing mold of the oil pan baffle structure, reduce the manufacturing cost of the oil pan baffle, and shorten its development cycle. Furthermore, by arranging the return oil pipe 7 on the oil pan baffle, the lubricating oil is returned to a point of the oil pan, so that the lubricating oil flowing out of the engine and mixed with impurities is concentrated in one place of the oil pan, thereby improving the effective extraction of the lubricating oil by the oil pump and improving the system efficiency.

[0027] A filter screen 8 is connected in the filter space and is arranged on the flow path of the lubricating oil for filtering the lubricating oil.

[0028] An oil groove 9 is formed on the baffle body 1 and extends in the direction from the first mounting surface 2 to the second mounting surface 3. A mounting groove 10 is provided on the end face of the oil groove 9. A mounting portion 18 inserted into the mounting groove 10 is provided on the end face of the lower shell 4 to achieve positioning between the baffle body 1 and the lower shell 4. The end face of the lower shell 4 is attached to the oil groove 9 to form a filtering space, and the filter screen 8 is fixed between the oil groove 9 and the lower shell 4.

[0029] An oil receiving cap 11 is disposed at one end of the oil return pipe 7 away from the baffle body 1 , and the oil receiving cap 11 is disposed on the flow path of the lubricating oil.

[0030] The lubricating oil flowing from the engine into the oil return pipe 7 first enters the oil receiving cap 11 , and only after the oil receiving cap 11 is overflowing, the lubricating oil flows back into the oil pan. This design is intended to retain larger iron filings in the lubricating oil in the oil receiving cap 11 .

[0031] A plurality of ribs 12 are provided inside the oil receiving cover 11, and the ribs 12 are connected between the side wall and the bottom wall of the oil receiving cover 11. The other side of the ribs 12 is fixed to the outer wall of the return oil pipe 7, so as to create a gap between the return oil pipe 7 and the oil receiving cover 11, so that the lubricating oil can flow smoothly from the return oil pipe 7 into the oil receiving cover 11. Preferably, the ribs 12 are L-shaped.

[0032] A support column 13 is provided on the oil tank 9, and one end of the support column 13 abuts against the filter screen 8 to fix the filter screen 8 in the filtering space.

[0033] The baffle body 1 has a first sealing groove 14 arranged around the oil outlet 17, and a second sealing groove 15 arranged around the oil return pipe 7. Sealing rings 16 are fixed in the first sealing groove 14 and the second sealing groove 15. The sealing ring 16 in the first sealing groove 14 is used to achieve sealing between the sealing channel and the oil pump, and the sealing ring 16 set in the second sealing groove 15 is used to achieve sealing between the oil return pipe 7 and the engine.

[0034] Preferably, the baffle body 1 and the lower shell 4, as well as the baffle body 1 and the oil return pipe 7 are connected by welding.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).
