Description

Technical Field

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

[0002] The engine oil pan is the lower part of the crankcase, and its main function is to store engine oil and seal the crankcase. During engine operation, moving parts such as the crankshaft and connecting rods violently agitate the engine oil, and the engine's own vibrations and impacts from the road surface are also directly transmitted to the oil pan, causing the oil pan shell to vibrate.

[0003] The high-temperature liquid mixture inside the oil pan, fuel that has seeped into the crankcase, and water produced by combustion can generate a lot of mixed gas as the oil pan shakes, reducing the lubricating effect of the oil.

[0004] Currently, baffles are usually installed at the bottom of the oil pan to suppress oil sloshing. However, under extreme conditions, such as rapid acceleration or sudden braking, the oil level can still slosh, which may lead to the risk of the oil pump sucking up air. Utility Model Content

[0005] In view of the defects or deficiencies in the prior art, this utility model provides an engine oil pan that ensures that the oil level in the chamber where the oil pump suction port is located can be kept relatively stable even under extreme dynamic operating conditions, greatly reducing the risk of air suction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An embodiment of this utility model provides an engine oil pan, including an oil pan body. Multiple oil baffles are arranged in parallel in the inner cavity of the oil pan body. The multiple oil baffles divide the inner cavity of the oil pan body into multiple interconnected independent chambers. The oil baffles are provided with circular holes, and the circular holes on adjacent oil baffles are arranged alternately.

[0007] Furthermore, the multiple oil baffles are arranged side by side along the length of the oil pan body, and there is a set distance between two adjacent oil baffles, thereby effectively dividing the large inner cavity of the oil pan body, reducing the amplitude of oil sloshing within the oil pan body, and physically disrupting the conditions for large-scale oil sloshing.

[0008] Furthermore, the shape of the oil baffle is the same as the cross-sectional shape of the inner cavity of the oil pan body, so that the oil baffle divides the inner cavity of the oil pan body.

[0009] Furthermore, the height of the oil baffle is less than the height of the oil pan body, so it will not interfere with the installation of the oil pan.

[0010] Furthermore, the oil baffle is set perpendicular to the bottom surface of the oil pan body to maximize the oil-blocking area and improve the oil-blocking effect.

[0011] Furthermore, the two sides of the oil baffle are fixedly connected to the two side walls of the oil pan body to ensure the stability of the oil baffle in the inner cavity of the oil pan body.

[0012] Furthermore, the lower edge of the oil baffle is spaced at a certain distance from the bottom surface of the oil pan body, thereby connecting the four independent chambers to each other and preventing local liquid levels from being too high or too low.

[0013] Furthermore, the diameter of the circular hole is less than half the height of the oil baffle plate to avoid the circular hole diameter being too large and affecting the oil-blocking effect.

[0014] Furthermore, the circular hole is located at the lower part of the oil baffle plate and is set close to the side wall of the oil pan body, so that the circular hole is submerged below the oil surface, ensuring that the oil can flow through the circular hole.

[0015] Furthermore, the round holes on the two adjacent oil baffles are respectively set close to the side walls of the oil pan body, thereby forming an S-shaped oil passage between the oil baffles. The oil in the independent chamber can slowly pass through the round holes, which can effectively consume the kinetic energy of the oil waves and transform the large-scale violent liquid surface sloshing into a small-scale turbulence, greatly enhancing the sloshing suppression effect.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a solution by arranging multiple oil baffles side by side in the inner cavity of the oil pan body. These baffles divide the inner cavity of the oil pan body into multiple interconnected independent chambers, thereby effectively dividing the large inner cavity of the oil pan body and reducing the amplitude of oil sloshing within the oil pan body. This physically disrupts the conditions for large-scale oil sloshing.

[0017] 2. This utility model has round holes on the oil baffle plate, and the round holes on two adjacent oil baffle plates are arranged in an alternating manner. The round hole structure allows the oil to pass through slowly while effectively consuming the kinetic energy of the oil waves, transforming large-scale violent liquid surface sloshing into small-scale turbulence, which greatly enhances the sloshing suppression effect.

[0018] 3. This utility model extends the lower edge of the oil baffle plate to a position close to the bottom of the oil pan body, and is spaced a certain distance from the bottom surface of the oil pan body, so that multiple independent chambers are interconnected. At the same time, a round hole is opened on the oil baffle plate to allow the oil to pass through slowly, thereby balancing the oil pressure in each chamber. This allows the oil to pass through the oil baffle plate smoothly when the vehicle's posture changes, so that the oil level in each divided chamber tends to be consistent, avoiding the formation of local oil levels that are too high or too low, which could cause the oil to suck in air. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the engine oil pan structure in an embodiment of the present invention; The components include: 1. Oil pan body; 2. Oil baffle; 3. Round hole. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] A typical embodiment of this utility model is as follows: Figure 1 As shown, an engine oil pan includes an oil pan body 1. Multiple oil baffles 2 are arranged in the inner cavity of the oil pan body 1. The multiple oil baffles 2 are arranged in parallel, and the interval between two adjacent oil baffles 2 is equal. The multiple oil baffles 2 divide the inner cavity of the oil pan body 1 into multiple interconnected independent chambers, thereby effectively dividing the large inner cavity of the oil pan body 1, reducing the amplitude of oil sloshing in the oil pan body 1, and physically destroying the conditions for the formation of large-scale oil sloshing.

[0022] Three oil baffles 2 are provided, arranged side by side along the length of the oil pan body 1, with a set distance between adjacent oil baffles 2. The shape of the oil baffles 2 is the same as the cross-sectional shape of the inner cavity of the oil pan body 1, thereby dividing the inner cavity of the oil pan body 1 into four independent chambers. Specifically, the height of the oil baffles 2 is less than the height of the oil pan body 1 to avoid interference with the installation of the oil pan body 1. The oil baffles 2 are set perpendicular to the bottom surface of the oil pan body 1 to maximize the oil-blocking area and improve the oil-blocking effect. Their two sides are fixedly connected to the two side walls of the oil pan body 1 to ensure the stability of the oil baffles 2 in the inner cavity of the oil pan body 1. The upper edge of the oil baffles 2 is lower than the upper surface of the oil pan body 1, and the lower edge of the oil baffles 2 extends to a position close to the bottom of the oil pan body 1, and is spaced a set distance from the bottom surface of the oil pan body 1, thereby allowing the four independent chambers to communicate with each other and preventing local liquid levels from being too high or too low.

[0023] The oil baffle 2 has a circular hole 3. The diameter of the circular hole 3 is less than half the height of the oil baffle 2 to avoid the circular hole 3 being too large and affecting the oil blocking effect. The circular hole 3 is located at the lower part of the oil baffle 2 and is set close to the side wall of the oil pan body 1 so that the circular hole 3 is submerged below the oil surface, ensuring that the oil can pass through the circular hole 3. The circular holes 3 on two adjacent oil baffles 2 are staggered, that is, the circular holes 3 on two adjacent oil baffles 2 are respectively set close to the two side walls of the oil pan body 1, thereby forming an S-shaped oil passage between the oil baffles 2, and the oil in the independent chamber can slowly pass through the circular hole 3.

[0024] By setting circular holes 3 on the oil baffle 2, and staggering the circular holes 3 on adjacent oil baffles 2, on the one hand, the oil pressure in each chamber can be balanced, allowing the oil to pass through the oil baffle 2 smoothly when the vehicle's posture changes, so that the oil level in each divided chamber can be made more consistent, avoiding local oil levels that are too high or too low; on the other hand, the circular hole 3 structure can effectively consume the kinetic energy of the oil wave while allowing the oil to pass through slowly, transforming large-scale violent liquid surface sloshing into small-scale turbulence, greatly enhancing the sloshing suppression effect.

[0025] Under severe transient conditions such as rapid acceleration and sudden braking, the multiple baffles 2 inside the oil pan body 1 divide the inner cavity of the oil pan body 1 into multiple interconnected independent chambers, effectively dividing the large inner cavity of the oil pan body 1 and reducing the amplitude of oil sloshing within the oil pan body 1. This physically disrupts the conditions for large-scale oil sloshing. At the same time, the circular holes 3 on the baffles 2 allow the oil to pass through slowly while effectively consuming the kinetic energy of the oil waves, transforming large-scale severe liquid surface sloshing into small-scale turbulence, greatly enhancing the sloshing suppression effect. In addition, the lower edge of the baffles 2 extends to near the bottom of the oil pan body 1 and is spaced a certain distance from the bottom surface of the oil pan body 1, thereby connecting the multiple independent chambers and making the oil level in each divided chamber tend to be consistent, avoiding local oil levels that are too high or too low, which could cause oil cavitation.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
