The oil baffle main body acts like a barrier, which can block the centrifugal force generated during the rotation of the crankshaft to prevent lubricating oil from being thrown out of the crankcase. The oil return holes on the oil baffle main body guide the flow of lubricating oil back to the oil sump. When lubricating oil is thrown onto the oil baffle main body, it will flow back to the oil sump through the oil return holes, ensuring the continuous lubrication and cooling of the engine. This design not only improves the reliability of the engine, but also prolongs the service life of the lubricating oil.

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] For example, Figure 1As shown, an engine oil baffle includes a baffle body 1, which is provided with several reinforcing ribs near the side edges, preferably three reinforcing ribs in this embodiment. The reinforcing ribs are rectangular and arranged along the length of the side edges, with the reinforcing ribs being recessed downward. The recessed bottom of the reinforcing ribs is provided with several oil return holes along the length direction. The bottom reinforcing rib 2 is provided with three oil return holes 5, and the top reinforcing rib 3 is provided with two oil return holes 5. The side reinforcing ribs are provided with two oil return holes 5 each. The multiple oil return holes 5 in each reinforcing rib are evenly arranged, with oil return holes 5 being provided near both ends. This arrangement is conducive to guiding the oil on the edges to flow back to the oil pan bottom, ensuring smooth flow of lubricating oil into the oil pan 8. The baffle body 1 acts like a barrier, blocking the centrifugal force generated during the rotation of the crankshaft, preventing lubricating oil from being thrown out of the crankcase. The oil return holes on the baffle body 1 serve to guide the flow of lubricating oil back. When the lubricating oil is thrown onto the baffle body 1, it will flow back to the oil pan 8 through the oil return holes, ensuring continuous lubrication and cooling of the engine. This design not only improves the reliability of the engine, but also prolongs the service life of the lubricating oil. Because it reduces the splashing and waste of lubricating oil, it can keep the engine clean and reduce the risk of failure caused by insufficient lubricating oil.

[0021] As Figure 1 and Figure 2As shown, in the preferred embodiment, the oil baffle body 1 is provided with a plurality of mounting holes 4. In this embodiment, the mounting holes 4 are circular holes, some large and some small, with a total of three large mounting holes 4 and six small mounting holes 4. The mounting holes 4 are used to pass through screws for fastening the oil baffle to the engine oil pan 8 with bolts and other fasteners, ensuring the stability and reliability of the oil baffle during engine operation. Or for giving way to other components. On the one hand, by passing through screws, bolts and other fasteners, the oil baffle can be firmly fixed to the engine oil pan 8. During high-speed operation of the engine, intense vibration and impact forces will be generated, and the close fit of these mounting holes 4 and fasteners can effectively resist these external forces, ensuring that the oil baffle always maintains a stable position and does not loosen or shift, thereby providing a solid foundation for the oil baffle to perform its function of blocking lubricating oil. On the other hand, the mounting holes 4 of different sizes also have high flexibility. In the complex internal structure of the engine, the layout of each component is compact and the installation space is limited. These mounting holes 4 can be cleverly given way to other components according to actual installation needs. For example, when the installation position of some sensors conflicts with the installation area of the oil baffle, the small mounting holes 4 can avoid the installation position of the sensors, or the large mounting holes 4 can adjust the position of the fasteners to reserve enough space for the cables of the sensors. This flexible design greatly improves space utilization, avoids component interference problems caused by insufficient space during installation, makes the entire engine installation process smoother, improves assembly efficiency, and also enhances the stability and reliability of the overall engine structure.

[0022] In a preferred embodiment, the oil baffle body 1 is a T-shaped plate, installed between the crankcase and the oil pan 8. Several U-shaped notches of varying sizes are provided on one side of the T-shaped plate near the U-shaped portion 2.1 of the bottom reinforcing rib 2, to allow space for bolts and other fasteners or other components. The oil baffle body 1 of this invention employs a unique T-shaped plate design, which allows it to perfectly fit and be installed between the crankcase and the oil pan 8. The space between the crankcase and the oil pan 8 has a special shape, thus ensuring a stable installation of the oil baffle within this space. Several U-shaped notches of varying sizes are distributed on the side of the T-shaped plate near the U-shaped portion of the bottom reinforcing rib 2. During engine assembly, the installation position of bolts and other fasteners is often limited by various factors. The presence of these U-shaped notches cleverly provides sufficient installation space for bolts and other fasteners, preventing situations where bolts cannot be properly installed due to obstruction by the oil baffle. Simultaneously, the U-shaped notches also provide necessary clearance for other structural components inside the engine, such as oil pipes and cables. For example, when the oil pipe needs to pass near the baffle plate, the U-shaped notch allows the pipe to pass smoothly without colliding with or being squeezed by the baffle plate. This design greatly improves the ease of installation, making the engine assembly process more efficient and smooth. Moreover, because the installation process is smoother, the risk of component damage or loosening due to improper installation is reduced, thereby improving the reliability of the entire engine system.

[0023] In a preferred embodiment, the bottom reinforcing rib 2 is bent into a U-shape near the T-corner. The reinforcing rib not only increases the structural strength of the oil baffle but also provides some flow guidance. From a structural strength perspective, the reinforcing rib itself enhances the overall rigidity of the oil baffle, and bending it into a U-shape further optimizes its mechanical properties. During engine operation, the oil baffle is subjected to various external forces, including centrifugal force from crankshaft rotation, impact force from lubricating oil, and vibration from the engine itself. The U-shaped reinforcing rib better disperses these external forces, improving the oil baffle's resistance to deformation and ensuring it maintains a stable shape and structure even under complex operating conditions, thus ensuring the oil baffle's oil-blocking function remains unaffected. From a flow guidance perspective, when lubricating oil is ejected by the high-speed rotation of the crankshaft, some of it impacts the bottom reinforcing rib 2. The reinforcing rib guides this lubricating oil along a specific path, preventing it from splashing everywhere and allowing it to flow more orderly towards the return oil hole, thus smoothly returning to the oil pan 8. This guiding effect not only improves the efficiency of lubricating oil recovery and reduces lubricating oil waste, but also keeps the inside of the engine clean and reduces the risk of malfunctions caused by lubricating oil splashing onto other unnecessary parts.

[0024] In a preferred embodiment, a mounting hole 4 is provided below the U-shaped portion 2.1 of the bottom reinforcing rib 2. This mounting hole 4 is a small mounting hole 4, and it is located on the same line as the other oil return holes 5 inside the bottom reinforcing rib 2. From an installation perspective, using this small mounting hole 4 for fastening can further enhance the stability of the oil baffle installation. From the perspective of lubricating oil return, it is on the same straight line as the oil return hole 5, which can guide the flow of lubricating oil to a certain extent. When the lubricating oil reaches this point after being guided by the reinforcing rib, this small mounting hole 4 can play an auxiliary guiding role, allowing the lubricating oil to flow back to the oil pan 8 more smoothly through the oil return hole 5, improving the efficiency and stability of lubricating oil return, and ensuring that the engine's lubrication system can work continuously and stably.

[0025] In a preferred embodiment, the top reinforcing rib 3 is bent at one end near the U-shaped portion 2.1 of the bottom reinforcing rib 2. The top reinforcing rib 3 forms an L-shape. This L-shaped top reinforcing rib 3 not only increases the structural strength of the oil baffle but also better guides the flow of lubricating oil, reducing splashing and waste, and improving engine lubrication. The L-shaped top reinforcing rib 3 alters its own stress distribution, enabling it to better withstand various complex external forces from inside the engine. Through a reasonable structural design, the L-shaped reinforcing rib effectively disperses and transmits these external forces, enhancing the deformation resistance of the top of the oil baffle and ensuring the integrity of the overall structure. The L-shaped structure plays a significant role in guiding the flow of lubricating oil. When lubricating oil is thrown towards the top of the oil baffle, the bent portion of the L-shape acts like a guide channel, guiding the oil to flow in a specific direction. It effectively changes the trajectory of the lubricating oil, preventing unnecessary splashing and directing it towards the return oil hole or oil pan 8, thus greatly reducing lubricating oil waste. At the same time, because the lubricating oil can flow more orderly, the lubrication effect inside the engine is significantly improved, all parts that need lubrication can be fully lubricated, reducing wear between parts and extending the service life of the engine.

[0026] In a preferred embodiment, the bend 3.1 of the top reinforcing rib 3 faces the bottom reinforcing rib 2, that is, it bends towards the middle of the oil baffle. When lubricating oil is splashed onto the top reinforcing rib 3, the lubricating oil will flow towards the oil return hole 5 under the guidance of the bend 3.1 because the bending direction is towards the middle of the oil baffle.

[0027] In a preferred embodiment, the baffle plate has a rectangular hole 6 at its center, with rounded ends. The rectangular hole 6 effectively reduces the overall weight of the baffle plate. In engine design, reducing component weight is crucial for improving engine performance and fuel economy. A lighter baffle plate reduces the load on the engine during operation, lowers energy consumption, and also helps improve engine response speed. The internal space of an engine is extremely compact, requiring a rational layout of all components. This rectangular hole 6 provides valuable space for other components inside the engine, improving space utilization and avoiding the problem of unreasonable component layout due to insufficient space. When the baffle plate is subjected to external forces, stress concentration is prone to occur at sharp corners, which can lead to premature fatigue cracks or even breakage in these areas. The rounded end design effectively disperses stress, making the stress more evenly distributed at the edge of the hole, thereby greatly improving the durability of the baffle plate, extending its service life, reducing the frequency of replacement due to baffle plate damage, and lowering maintenance costs.

[0028] In a preferred embodiment, the rectangular hole 6 is located away from the side of the reinforcing rib. The trapezoidal hole 7 is designed to make way for other structures inside the engine, ensuring the compatibility of the oil baffle with other components, reducing interference during installation, and improving the efficiency and reliability of the overall assembly.

[0029] In a preferred embodiment, a trapezoidal hole 7 is provided on the side of the rectangular hole 6 away from the reinforcing rib, and the trapezoidal hole 7 is located between the bottom reinforcing rib 2 and the top reinforcing rib 3. The trapezoidal hole 7 is a trapezoid with an acute angle on the hypotenuse, used to make way for other engine structures. During the engine assembly process, the internal structure of the engine is complex and diverse, and the installation positions and space requirements between various components are very strict. The existence of the trapezoidal hole 7 provides precise clearance space for other internal engine structures. For example, when some irregularly shaped components need to be installed near the oil baffle, the trapezoidal hole 7 can be adapted according to the shape and size of these components, ensuring that they can be installed smoothly without interfering with the oil baffle. This design greatly improves the compatibility of the oil baffle with other components, making the overall engine assembly process smoother, reducing problems such as extended assembly time and component damage caused by installation interference, improving the efficiency and reliability of the overall assembly, and helping to ensure the production quality and schedule of the engine.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
