[0046] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] Hereinafter, an oil pan 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0048] according to Figures 1-6As shown, the oil pan 1 according to an embodiment of the present invention includes: a shell 11 and a partition 12, an oil storage chamber 111 is provided in the shell 11, and an oil inlet opening 1112 is provided at the top of the oil storage chamber 111; the partition 12 is provided in the shell 11 to separate the oil storage chamber 111 into multiple oil return partitions 1111, and at least two oil return partitions 1111 are connected.

[0049] Therefore, the partition 12 can be used to prevent the lubricating oil from gathering, and the connection of at least two oil return partitions 1111 can enable the lubricating oil to be more evenly distributed to multiple oil return partitions 1111, so as to reduce the risk of air suction at the oil suction port 21, so that multiple oil return partitions 1111 can return oil together, ensuring the oil return efficiency and improving the reliability of the oil pan 1.

[0050] First, if Figure 1-Figure 5 As shown, engine 100 includes an oil pan 1, a main cylinder 3, and a scavenge pump assembly 2. The oil pan 1 is located below and communicates with the main cylinder 3, sealing the main cylinder 3 from the bottom to prevent impurities from entering the lower portion. The oil pan 1 can also be used to temporarily collect and store lubricating oil that flows back from areas within the main cylinder 3 requiring lubrication (e.g., the crankshaft surface, intake and exhaust VVT), thereby enabling lubricating oil recycling. The scavenge pump assembly 2 can also be installed within the oil pan 1 to return the lubricating oil from the oil pan 1.

[0051] Among them, the oil pan 1 includes a shell 11 and a partition 12. An oil storage chamber 111 is provided in the shell 11. An oil inlet opening 1112 is provided at the top of the oil storage chamber 111. The oil inlet opening 1112 is opposite to the main cylinder body 3. The lubricating oil in the main cylinder body 3 can flow into the oil storage chamber 111 through the oil inlet opening 1112 to be stored in the oil storage chamber 111.

[0052] A partition 12 is disposed within the housing 11. The partition 12 is used to separate the oil storage chamber 111 into a plurality of oil return partitions 1111, so that the majority of the lubricating oil that returns to the oil pan 1 can be concentrated in each oil return partition 1111. The plurality of oil return partitions 1111 are relatively independent, and at least two of the oil return partitions 1111 are interconnected. For example, four oil return partitions 1111 can be provided, with any two adjacent oil return partitions 1111 interconnected, so that the four oil return partitions 1111 are interconnected, allowing the lubricating oil to be evenly distributed throughout the four oil return partitions 1111. Alternatively, the four oil return partitions 1111 can be divided into two groups, with the two oil return partitions 1111 in each group interconnected, allowing the lubricating oil to be evenly distributed throughout the two interconnected oil return partitions 1111. In this manner, the lubricating oil can be relatively evenly distributed throughout the plurality of oil return partitions 1111, ensuring that each oil return partition 1111 has sufficient lubricating oil.

[0053] At the same time, multiple oil suction ports 21 can be provided on the return oil pump assembly 2, and the multiple oil suction ports 21 correspond one-to-one to and are connected with the multiple return oil partitions 1111, so that the return oil pump assembly 2 can suck oil from the multiple return oil partitions 1111 through the multiple oil suction ports 21 respectively.

[0054] It should be noted that due to the differences in the amount of lubricating oil returning to each position of the main cylinder 3, the amount of lubricating oil in each return oil partition 1111 is uneven due to the separation of the partition 12, that is, the lubricating oil will be concentrated on one side of the oil pan 1, which may cause part of the oil suction port 21 of the return oil pump assembly 2 to be sucked empty, so that a series of moving parts of the engine 100 cannot be effectively lubricated. In the related technology, multiple return oil partitions 1111 are set to block the flow of lubricating oil to prevent the return oil pump assembly 2 from being sucked empty, but the return oil amount in the multiple return oil partitions 1111 is insufficient and uneven, and the return oil pump assembly 2 still has the risk of being sucked empty.

[0055] To address the above issues, by dividing the oil reservoir 111 into multiple oil return partitions 1111 and connecting at least two of the oil return partitions 1111, the lubricating oil within the oil reservoir 111 is relatively evenly distributed across the multiple oil return partitions 1111. This allows the oil return pump assembly 2 to simultaneously return oil from multiple oil return partitions 1111, thereby improving oil return efficiency. Furthermore, when the engine 100 tilts, such as to the left, right, forward, or backward, the partition 12 creates a barrier to the lubricating oil, preventing it from pooling. This allows the oil return pump assembly 2 to continue returning oil from multiple oil return partitions 1111, thereby improving the oil return stability of the oil return pump assembly 2.

[0056] According to the oil pan 1 of the embodiment of the present invention, the oil storage chamber 111 can be divided into multiple oil return partitions 1111 by providing a partition 12, and at least two oil return partitions 1111 are provided to be connected, so that the lubricating oil can be more evenly distributed to the multiple oil return partitions 1111, so as to ensure that the multiple oil return partitions 1111 can return oil together, thereby improving the oil return efficiency, and when the engine 100 is tilted, the partition 12 can be used to prevent the lubricating oil from gathering, so as to reduce the risk of air absorption and improve the reliability of the oil pan 1.

[0057] In some embodiments of the present invention, a plurality of oil return partitions 1111 are distributed in the first direction F1 and a plurality of oil return partitions 1111 are distributed in the second direction F2, and the first direction F1 and the second direction F2 are intersecting.

[0058] For example, the first direction F1 can be set as the front-to-back direction, and the second direction F2 can be set as the left-to-right direction, and the oil return partitions 1111 can be set as two groups, and the two groups of oil return partitions 1111 are spaced apart along the front-to-back direction, each group has two oil return partitions 1111, and the two oil return partitions 1111 in each group are spaced apart along the left-to-right direction.

[0059] Through the above settings, the division of the oil return partition 111 can be made more reasonable. When the engine 100 encounters extreme working conditions, such as left forward tilt, right rear tilt, etc., multiple oil return partitions 1111 can still return oil together, which improves the oil return efficiency and helps reduce the risk of air absorption.

[0060] In some embodiments of the present invention, the partition 12 includes a main body 121 and a plurality of extension portions 122. The main body 121 is located in the middle of the oil storage chamber 111. The plurality of extension portions 122 are connected to the main body 121 at circumferential intervals and extend toward the side wall of the oil storage chamber 111. An oil return partition 1111 is defined between two adjacent extension portions 122.

[0061] For example, refer to Figure 4 As shown, the partition 12 includes a main body 121 and an extension portion 122. The main body 121 is located in the middle of the oil storage chamber 111. The extension portion 122 is provided in plurality, and the plurality of extension portions 122 are arranged at intervals along the circumference of the main body 121. One end of the extension portion 122 is connected to the main body 121 and the other end is extended toward the side wall of the oil storage chamber 111. The two adjacent extension portions 122 face each other on one side and together with the side wall of the oil storage chamber 111 to define the oil return partition 1111.

[0062] Through the above arrangement, the distribution of the oil return partitions 1111 can be made more uniform, which is beneficial to improving the design rationality of the oil pan 1 and can increase the modal frequency of the oil pan 1, thereby improving the NVH performance of the engine 100.

[0063] In some embodiments of the present invention, Figure 4 As shown, an oil gap 13 can be provided between at least a portion of the extension 122 and the sidewall of the oil storage chamber 111, and at least two adjacent oil return partitions 1111 can be connected through the oil gap 13. This arrangement allows the oil gap 13 to be positioned away from the main body 121. When the engine 100 tilts, lubricating oil is less likely to flow through the oil gap 13 to the other oil return partition 1111, thereby improving the barrier effect of the partition 12 and ensuring the oil return efficiency of the oil pan 1.

[0064] In other embodiments of the present invention, the end of the extension portion 122 facing away from the main body portion 121 can be connected to the side wall of the oil storage chamber 111, and a through hole can be provided on the extension portion 122 to connect adjacent oil return partitions 1111. This facilitates meeting different design requirements.

[0065] In some embodiments of the present invention, Figure 4 and Figure 6As shown, the bottom wall of the oil gap 13 can be set lower than the bottom wall of the oil return partition 1111 connected to the oil gap 13, so that the lubricating oil in the corresponding oil return partition 1111 can all flow into the oil gap 13. Through this arrangement, the lubricating oil in the multiple oil return partitions 1111 can be more evenly distributed, improving the design rationality of the oil pan 1.

[0066] In some embodiments of the present invention, Figure 3-Figure 5 As shown, a portion of the bottom wall of each oil return partition 1111 can be provided with an oil suction trough 112, and the oil suction trough 112 is arranged opposite to the oil suction port 21 of the oil return pump assembly 2, so that the oil suction port 21 can return oil from the oil suction trough 112.

[0067] It can be understood that by providing the oil suction trough 112, the lubricating oil in the return oil partition 1111 can be gathered into the oil suction trough 112, so that the oil suction port 21 can more easily extract the lubricating oil, and when the engine 100 is tilted, the oil suction trough 112 can form a certain obstruction to the flow of the lubricating oil, thereby reducing the outflow of the lubricating oil and improving the oil return stability.

[0068] In some embodiments of the present invention, Figure 3 As shown, a portion of the bottom of the housing 11 may be recessed downward to define an oil suction groove 112. This simplifies the structure of the housing 11, reduces the difficulty of machining the oil suction groove 112, and improves the practicality of the oil pan 1.

[0069] In some embodiments of the present invention, Figure 4 As shown, a portion of the partition 12 can be arranged around the oil suction trough 112. With this arrangement, when the engine 100 shakes, the partition 12 can provide some obstruction to the lubricating oil, thereby reducing the degree of sloshing of the oil in the oil return partition 1111, especially the oil in the oil suction trough 112, thereby reducing the risk of cavitation at the oil suction port 21 and improving the stability of the engine 100.

[0070] In some embodiments of the present invention, Figure 3 As shown, the depth H1 of the oil suction groove 112 can be set to be no less than 3 mm, for example, 3 mm, 4 mm, 5 mm, etc. Through the above configuration, the oil suction groove 112 can be made easier to process, reducing the difficulty of processing the oil pan 1, and the oil suction groove 112 can better collect the lubricating oil, ensuring the stability of oil return.

[0071] In some embodiments of the present invention, Figure 4As shown, at least a portion of the sidewall of the oil reservoir 111 can be configured to extend downward and toward the oil return partition 1111 to define a guide slope 113. The guide slope 113 is used to guide the lubricating oil flowing down from the main cylinder 3 into the oil reservoir 111. This can increase the speed at which the oil pan 1 collects the lubricating oil, thereby increasing the circulation speed of the lubricating oil and improving the overall performance of the engine 100.

[0072] In some embodiments of the present invention, Figure 4 As shown, each oil return partition 1111 can be provided with a corresponding guide slope 113. In other words, the sidewalls of the oil storage chamber 111 can be provided with guide slopes 113 corresponding to the multiple oil return partitions 1111. This can increase the speed at which the oil pan 1 collects lubricating oil, and can ensure that the lubricating oil within the multiple oil return partitions 1111 is more evenly distributed, thereby improving the practicality of the oil pan 1.

[0073] In some embodiments of the present invention, Figure 3 As shown, the protruding height H2 of the separator 12 can be set to be no less than 13 mm, for example, 14 mm, 15 mm, 16 mm, etc. Through the above configuration, the barrier effect of the separator 12 can be ensured, so that the upper oil return partition 1111 can have sufficient lubricating oil, which helps prevent cavitation and improves the design rationality of the oil pan 1.

[0074] In some embodiments of the present invention, Figure 3 As shown, the housing 11 and the separator 12 can be formed as an integral part, such as by integral die-casting. This arrangement can reduce the difficulty of machining the oil pan 1, increase the structural strength of the oil pan 1, and improve the reliability of the oil pan 1.

[0075] In some embodiments of the present invention, Figure 3 As shown, a portion of the bottom wall of the housing 11 may be provided to protrude upward to define the partition 12. This can save materials, reduce costs, and make the overall weight of the oil pan 1 lighter, thereby facilitating a lightweight design.

[0076] The present invention also provides an engine 100 .

[0077] According to an embodiment of the present invention, the engine 100 includes: an oil pan 1 and a return oil pump assembly 2, wherein the oil pan 1 is the oil pan 1 according to any of the above embodiments; the return oil pump assembly 2 has multiple oil suction ports 21, and the multiple oil suction ports 21 correspond one-to-one to the multiple return oil partitions 1111.

[0078] For example, refer to Figures 1-6As shown, the engine 100 includes an oil pan 1 and a main cylinder 3. The oil pan 1 is arranged at the lower part of the main cylinder 3 and is connected to the main cylinder 3, so as to seal the main cylinder 3 at the lower part of the main cylinder 3 to prevent impurities from entering the lower part of the main cylinder 3. The oil pan 1 can be used to temporarily collect and store the lubricating oil flowing back from the parts of the main cylinder 3 that need lubrication (such as the crankshaft surface, intake VVT, exhaust VVT, etc.) to achieve the recycling of the lubricating oil.

[0079] The engine 100 also includes a return oil pump assembly 2 and an oil reservoir. The return oil pump assembly 2 is installed in the oil pan 1. The return oil pump assembly 2 is connected to the oil reservoir so that the return oil pump assembly 2 can return the lubricating oil in the oil pan 1 and store the lubricating oil in the oil reservoir.

[0080] The oil pan 1 is provided with an oil storage chamber 111, which is divided into a plurality of oil return partitions 1111. A plurality of oil suction ports 21 are provided on the bottom wall of the oil return pump assembly 2. The plurality of oil suction ports 21 correspond one-to-one with and are connected to the plurality of oil return partitions 1111, so that the oil return pump assembly 2 can return oil to the corresponding oil return partitions 1111 through the plurality of oil suction ports 21. For example, four oil return partitions 1111 may be provided, and four corresponding oil suction ports 21 may be provided. The four oil suction ports 21 correspond one-to-one with and are connected to the four oil return partitions 1111.

[0081] According to the engine 100 of the embodiment of the present invention, the return oil pump assembly 2 can return oil to multiple return oil partitions 1111 through multiple oil suction ports 21 respectively, with high oil return efficiency. The return oil pump assembly 2 is not easy to suck air, thereby improving the operating stability of the engine 100.

[0082] In some embodiments of the present invention, Figure 3 As shown, the minimum gap H3 between the oil suction port 21 and the bottom wall of the oil storage chamber 111 can be set to be no less than 10 mm, for example, 11 mm, 12 mm, 13 mm, etc. It should be emphasized that the portion of the bottom wall of the oil storage chamber 111 corresponding to the oil suction port 21 can be planar or non-planar, as long as the minimum gap H3 between the portion of the bottom wall of the oil storage chamber 111 corresponding to the oil suction port 21 and the oil suction port 21 is no less than 10 mm.

[0083] It should be noted that during the operation of the engine 100, the lubricating oil may be mixed with some water vapor, resulting in the presence of liquid water in the oil reservoir 111. In low-temperature environments, this may cause ice to form in the oil pan 1, and the ice may block the oil suction port 21. To address this issue, a minimum gap of no less than 10 mm can be set between the oil suction port 21 and the bottom wall of the oil reservoir 111. This ensures that any ice condensed on the bottom wall of the oil reservoir 111 maintains a sufficient distance from the oil suction port 21. This reduces the risk of clogging the oil suction port 21 and improves the stability of the engine 100.

[0084] In some embodiments of the present invention, Figure 3 As shown, an oil suction groove 112 can be formed on the bottom wall of the oil storage chamber 111 corresponding to the oil suction port 21, so that the oil suction port 21 can return oil from the oil suction groove 112. The projected area of the oil suction port 21 on the bottom wall of the oil storage chamber 111 can be set to be smaller than the area of the oil suction groove 112, so that the oil suction port 21 can overlap with the oil suction groove 112 in the vertical direction, so that the distance between the oil suction port 21 and the bottom wall of the oil storage chamber 111 can be kept equal.

[0085] Through the above arrangement, the influence of the bottom wall of the oil storage chamber 111 on the lubricating oil can be reduced, so that the lubricating oil is not easy to form turbulence, the flow speed of the lubricating oil is increased, and the oil suction efficiency of the oil return pump assembly 2 is improved.

[0086] The present invention further proposes a hybrid assembly.

[0087] A hybrid powertrain according to an embodiment of the present invention includes: an engine 100 according to any one of the above embodiments.

[0088] The hybrid assembly according to the embodiment of the present invention has high operating stability and good overall performance, which is conducive to improving the overall performance of the vehicle.

[0089] The present invention further provides a vehicle.

[0090] A vehicle according to an embodiment of the present invention includes a hybrid powertrain assembly according to any of the aforementioned embodiments. It should be noted that the oil pan 1 is located below the hybrid powertrain assembly. Due to structural limitations, the oil pan 1 is constructed as a flat structure. Therefore, multiple oil suction ports 21 can be provided to make the scavenge pump assembly 2 flatter overall, thereby allowing the scavenge pump assembly 2 to be disposed within the oil pan 1.

[0091] The vehicle according to the embodiment of the present invention has good overall operational stability, which is conducive to improving user satisfaction.
