Description

Technical Field

[0001] This application relates to the field of vehicle engine technology, and in particular to an oil pan, an engine, and a vehicle. Background Technology

[0002] Currently, the oil pan is the component in a vehicle's engine that stores engine oil. To meet the oil consumption requirements of the vehicle's overall climbing angle and maintenance mileage, it usually needs to have a large volume.

[0003] In related technologies, the vertical dimensions of the oil pan are reduced to meet the design requirements for vehicle ground clearance, resulting in a smaller oil storage capacity in the oil pan. When the vehicle is under specific operating conditions (such as rapid acceleration, climbing, or tilting), the oil in the oil pan disperses (e.g., accumulates to one side), making it difficult to extract the oil and affecting the oil circulation efficiency in the engine, leading to poor engine lubrication. Utility Model Content

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, one object of this application is to provide an oil pan in which the oil can preferably collect at a settling tank to ensure the effective extraction of oil from the oil pan.

[0005] According to an embodiment of the first aspect of this application, the oil pan is characterized in that the axial direction of the crankshaft in the engine is a first direction, the width direction of the engine is a second direction, and the oil pan includes: a shell body, the shell body having an upwardly open receiving groove, the receiving groove forming a recessed groove extending along the first direction in the middle of the second direction, the recessed groove being recessed from the bottom wall of the receiving groove, and the shell body having an oil suction port at the recessed groove for discharging engine oil from the receiving groove.

[0006] According to the oil pan of the present application embodiment, the oil pan can preferentially collect the engine oil in the sink, and the sink is provided with multiple oil suction ports to ensure the stability of oil extraction under various working conditions (such as acceleration, deceleration, climbing, and descending). In addition, the oil pan has a small vertical dimension, which can realize a flat body design, which helps to reduce the ground clearance of the engine.

[0007] According to some embodiments of this application, the engine is equipped with an oil filter, and the oil filter is located below the oil pan; a first mounting seat is formed at one end of the main body of the housing in the first direction, the first mounting seat is recessed into the receiving groove, and a first mounting cavity is formed below the main body of the housing, the first mounting seat is used to install the oil filter, and at least a portion of the oil filter is placed in the first mounting cavity. Thus, the oil pan can be used as a mounting carrier for the oil filter, and the oil filter can be integrated and installed at the bottom of the oil pan.

[0008] According to some embodiments of this application, the top surface of the first mounting base is disposed below the top surface of the housing body.

[0009] According to some embodiments of this application, the engine is provided with an oil cooler, and the housing body is further provided with a second mounting seat. The second mounting seat is located on one side of the first mounting seat in the second direction and is used to mount the oil cooler. At least a portion of the second mounting seat is disposed opposite to the first mounting cavity in the second direction. This allows the oil cooler and oil filter to be compactly arranged in the oil pan, improving the space utilization rate of the oil pan.

[0010] According to some embodiments of this application, the second mounting base is provided with a first connecting hole for connecting the oil cooler and the oil filter, so that oil in the oil cooler can flow into the oil filter through the first connecting hole; the first mounting base is also provided with a second connecting hole, one end of which is connected to the oil filter, and the other end of which is located in the receiving groove and opens to the cylinder block side of the engine for communication and engagement with the cylinder block. Thus, the oil filter and oil cooler can be connected at the oil pan, saving on the piping structure in the engine.

[0011] According to some embodiments of this application, the bottom wall of the shell body has a first guide surface and a second guide surface. The first guide surface and the second guide surface are respectively disposed on both sides of the settling tank in the second direction. The first guide surface extends downward at an angle from one edge of the shell body in the second direction to the open end of the settling tank, and the second guide surface extends downward at an angle from the other edge of the shell body in the second direction to the open end of the settling tank. This allows the lubricated oil to quickly converge at the settling tank, ensuring effective oil extraction at the settling tank.

[0012] According to some embodiments of this application, at least one of the first guide surface and the second guide surface is provided with a rib; wherein the rib protrudes inward toward the receiving groove; and / or, in its projection in the vertical direction, the rib extends along the second direction. This improves the structural strength of the shell body.

[0013] Another objective of this application is to propose an engine.

[0014] The engine according to the second aspect of this application includes the oil pan described above, and the axial direction of the engine is arranged parallel to the X-direction of the vehicle.

[0015] The advantages of the engine and the oil pan mentioned above compared to the prior art are the same, and will not be repeated here.

[0016] Another objective of this application is to propose a vehicle.

[0017] The vehicle according to the third aspect of this application includes the engine described above.

[0018] The advantages that the vehicle and the engine mentioned above have over the prior art are the same, and will not be repeated here.

[0019] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] The following is for reference. Figures 1-2 The present application describes an oil pan 10 for an engine, which is used to store engine oil.

[0024] Currently, the oil pan 10 is a component in the vehicle's engine that stores engine oil. To meet the oil consumption requirements of the vehicle's overall climbing angle and maintenance mileage, it usually needs a large volume.

[0025] In related technologies, the appearance and dimensions of the oil pan 10 vary depending on the vehicle model. To meet ground clearance design requirements, the vertical dimensions of the oil pan are reduced, resulting in a smaller oil storage capacity. Under specific operating conditions (such as rapid acceleration, hill climbing, or side tilting), the oil in the oil pan disperses (e.g., accumulates to one side), making it difficult to extract the oil and affecting its circulation efficiency in the engine, leading to poor engine lubrication. These vehicles can be MPVs (Multi-Purpose Vehicles), SUVs (Sport Utility Vehicles), etc.

[0026] In this application, the axial direction of the crankshaft in the engine is defined as the first direction, and the width direction of the engine is defined as the second direction.

[0027] Reference Figure 1 As shown, the oil pan 10 according to an embodiment of this application includes a main body 1. The main body 1 has an upwardly open receiving groove 101. The receiving groove 101 forms a sink 11 extending in a first direction at the middle of the second direction. The sink 11 is sunken from the bottom wall of the receiving groove 101. The main body 1 is provided with an oil suction port 102 at the sink 11. The oil suction port 102 is used to discharge the oil in the receiving groove 101.

[0028] It is understood that the oil pan 10 is used to connect and mate with the cylinder block in the engine, and the oil pan 10 is located at the bottom of the cylinder block. The receiving groove 101 is open to one side of the cylinder block, and the receiving groove 101 is used to hold engine oil. The engine oil used for lubrication can flow downward and collect in the receiving groove 101.

[0029] Furthermore, a pump assembly can be installed in the engine to cooperate with the oil suction port 102 to draw oil from the oil pan 10 and further deliver the oil to other parts of the engine (such as the oil tank), thereby realizing the circulation of oil in the engine, ensuring the lubrication performance of the engine, and helping to improve the engine's operational stability and reliability.

[0030] Reference Figure 1As shown, the housing body 1 has a further recessed groove 11 on the bottom wall of the receiving groove 101. The oil in the receiving groove 101 will preferentially gather at the groove 11 under the action of gravity. Moreover, the groove 11 is provided with an oil suction port 102, so that the pump assembly (not shown in the figure) can draw the oil in the groove 11 to ensure the oil drawing effect of the pump assembly at the oil pan 10, avoid the problem of suction cavitation, improve the drawing effect of the lubricating medium (i.e. the above-mentioned oil) in the engine at the oil pan 10, so that the lubricating medium can be effectively drawn and participate in the lubrication of the engine components.

[0031] It is understandable that when the aforementioned oil pan 10 is applied to an engine, the oil pan 10 is located at the bottom of the engine. In the vertical direction, the sink 11 is positioned low within the oil pan 10, allowing the engine oil in the receiving tank 101 to preferentially collect at the sink 11. This ensures that engine oil is constantly stored in the sink 11, achieving centralized storage of engine oil. Furthermore, the engine oil can be extracted through the oil suction port 102 in the sink 11, ensuring effective extraction of engine oil from the oil pan 10, preventing cavitation, and improving the stability of the engine oil supply.

[0032] It should be noted that in the relevant technology, a "dry lubrication system" is designed. In engines that use the above-mentioned "dry lubrication system", the oil pan 10 only has the function of "sealing the crankcase + temporary oil collection". As a result, the amount of oil that can be contained in the oil pan 10 is small and easily dispersed, making it difficult to extract the oil. This affects the circulation efficiency of the oil in the engine and results in poor engine lubrication.

[0033] According to the oil pan 10 of this application embodiment, the main body 1 stores engine oil through a receiving groove 101, and a lower recess 11 is provided on the bottom wall of the receiving groove 101, so that the main body 1 can achieve centralized storage of engine oil at the recess 11. This ensures the effective oil extraction through the oil suction port 102 in the recess 11, avoids the problem of cavitation, and improves the stability and reliability of the engine oil supply, ensuring continuous lubrication of engine components. In other words, even if the amount of engine oil that the oil pan 10 can hold in an engine using a dry lubrication system is limited, centralized storage of engine oil can be achieved through the recess 11, which helps to optimize the oil suction path of the oil collector (such as: pump assembly, etc.) and ensure the stability of the engine oil supply.

[0034] In a further embodiment of this application, the engine is provided with an oil filter (not shown in the figure), and the oil filter is located below the oil pan 10.

[0035] Combination Figure 1 and Figure 2As shown, a first mounting seat 12 is formed at one end of the housing body 1 in the first direction. The first mounting seat 12 is recessed into the inner side of the receiving groove 101, and a first mounting cavity 121 is formed in the lower direction of the housing body 1. The first mounting seat 12 is used to install an oil filter, and at least part of the oil filter is placed in the first mounting cavity 121 to install and fix the oil filter at the oil pan 10.

[0036] The oil filter is used to remove impurities such as dust, metal particles, carbon deposits, and soot particles from the engine oil to protect the engine. As you can understand, engine oil circulates in the engine's lubrication system to ensure proper lubrication. After being filtered by the oil filter, the oil can flow back into the engine block to continue its lubricating function.

[0037] In this application, by providing a first mounting seat 12 on the housing body 1, the oil filter can be directly fixed to the bottom of the oil pan 10, and the oil pan 10 can be used as the mounting carrier for the oil filter. This allows the oil filter and the oil pan 10 to be arranged compactly, which helps to save the arrangement space of the oil filter and improve the space utilization rate of the engine.

[0038] Furthermore, the first mounting base 12 is recessed into the inner side of the receiving groove 101 to form a downwardly open first mounting cavity 121 below the oil pan 10. The first mounting cavity 121 is used to accommodate at least part of the oil filter to reduce the downward protrusion of the oil filter relative to the bottom wall of the housing body 1, thereby reducing the vertical dimension of the oil pan 10 on which the oil filter is installed and saving vertical space.

[0039] Combination Figure 1 and Figure 2 As shown, the first mounting base 12 is disposed at one end of the housing body 1 in the first direction, thereby reducing the influence of the first mounting base 12 on the shape of the receiving groove 101. It is understood that if the first mounting base 12 is formed in the middle region of the housing body 1, the receiving groove 101 will be divided into two spaced sub-grooves, making the shape of the receiving groove 101 formed by the housing body 1 irregular, thereby affecting the oil extraction effect in the receiving groove 101.

[0040] Reference Figure 1 As shown, in some embodiments of this application, the top surface of the first mounting base 12 is set lower than the top surface of the shell body 1, thereby preventing interference between the first mounting base 12 and the cylinder.

[0041] It is understood that the oil pan 10 is used in the engine and is connected to the bottom of the engine block. In this application, the top surface of the first mounting seat 12 is set lower than the top surface of the housing body 1, so that the first mounting seat 12 will not intrude into the space on the side of the cylinder block, thereby avoiding interference between the first mounting seat 12 and the cylinder block and ensuring the assembly reliability of the oil pan 10 and the cylinder block.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the engine is provided with an oil cooler (not shown in the figure), and the housing body 1 is also provided with a second mounting seat 13. The second mounting seat 13 is located on one side of the first mounting seat 12 in the second direction, and the second mounting seat 13 is used to install the oil cooler. At least part of the second mounting seat 13 is disposed opposite to the first mounting cavity 121 in the second direction.

[0043] It should be noted that the oil cooler is used to cool the engine oil in order to lower its temperature.

[0044] In this application, a second mounting seat 13 is provided on the shell body 1. The second mounting seat 13 is the mounting carrier of the oil cooler, so that the oil cooler is fixed to the oil pan 10 through the second mounting seat 13, thereby realizing the assembly and fixation of the oil cooler in the engine, making the oil cooler and the oil pan 10 fit tightly, and facilitating the connection and cooperation between the oil cooler and the oil filter.

[0045] Combination Figure 1 and Figure 2 As shown, it can be understood that the first mounting seat 12 for installing the oil filter is located at one end of the housing body 1 in the first direction, and the second mounting seat 13 for installing the oil cooler is located on one side of the housing body 1 in the second direction. The first mounting seat 12 and the second mounting seat 13 are arranged adjacent to each other, so that the oil cooler and the oil filter can be arranged compactly, which facilitates the connection and cooperation between the oil cooler and the oil filter.

[0046] Furthermore, in the engine lubrication system, the engine oil cooled by the oil cooler can flow to the oil filter. After being filtered by the oil filter, the oil enters the engine block to lubricate the engine components. Therefore, by arranging the second mounting base 13 on one side of the first mounting cavity 121 in the second direction, this application allows the oil cooler to be positioned close to the oil filter. This enables the oil discharged from the oil cooler to flow into the oil filter through the oil pan 10, optimizing the oil delivery path, reducing the number of pipes in the engine, and improving space utilization in the engine area.

[0047] Currently, the oil pan 10 is located at the bottom of the engine, serving only as a seal for the crankcase and storing engine oil, thus wasting space at the bottom of the engine (e.g., between the oil pan 10 and the chassis). Meanwhile, the oil cooler and oil filter need to be located separately within the engine (e.g., on the side or front of the engine), resulting in these components occupying a large amount of engine compartment space and increasing the cost of connecting pipes within the engine (e.g., the pipe structure connecting the oil cooler and oil filter).

[0048] In this application, by integrating a first mounting base 12 and a second mounting base 13 onto the oil pan 10, the oil cooler and oil filter can be mounted and fixed onto the oil pan 10. This ensures a tight fit between the oil cooler and oil filter and the main body 1, saving engine compartment space required for arranging the oil cooler and oil filter. Furthermore, the close arrangement of the oil cooler and oil filter helps reduce the number of pipes in the engine and lowers pipe connection costs. In other words, by optimizing the flow path of oil in the oil pan 10, oil cooler, and oil filter, the number of pipes in the lubrication system of the engine is reduced, thus improving the space utilization rate of the engine.

[0049] like Figure 1 As shown, in some embodiments of this application, the first mounting base 12 is provided with a first connecting hole 131. The first connecting hole 131 is used to connect the oil cooler and the oil filter, so that the oil in the oil cooler can flow into the oil filter through the first connecting hole 131, so that the oil cooled by the oil cooler can enter the oil filter after flowing through the first connecting hole 131, thereby filtering the oil through the oil filter.

[0050] It is understandable that the first connecting hole 131 is equivalent to a pipeline structure integrated into the oil pan 10, used to connect the oil cooler and the oil filter, thereby reducing the number of pipelines in the engine and reducing the difficulty of installing, fixing and connecting various components in the engine (such as the aforementioned oil cooler and oil filter).

[0051] Combination Figure 1 and Figure 2 As shown, the first connecting hole 131 can be configured as a hole structure that extends through the second direction, so that the oil in the oil cooler located on the outer side of the second mounting base 13 in the second direction can flow through the first connecting hole 131 into the oil filter located on the inner side of the second mounting base 13 in the second direction.

[0052] In this application, the oil pan 10 serves as the mounting carrier for the oil cooler and the oil filter. A first connecting hole 131 for connecting the oil cooler and the oil filter is integrated in the oil pan 10 to achieve the connection and cooperation between the oil cooler and the oil filter. This can save on the connecting pipeline between the oil cooler and the oil filter, and the oil cooler and the oil filter are tightly assembled in the oil pan 10 to save the arrangement space required for the oil cooler and the oil filter, thereby improving the space utilization rate of the engine.

[0053] Reference Figure 1 As shown in a further embodiment of this application, the second mounting base 13 is further provided with a second connecting hole 132. One end of the second connecting hole 132 is connected to the oil filter, and the other end of the second connecting hole 132 is located in the receiving groove 101 and opens to the cylinder block side of the engine for communication and cooperation with the cylinder block, so that the oil in the oil filter can flow into the cylinder block through the second connecting hole 132 to realize the lubrication function of the engine components (such as piston, cylinder, crankshaft, etc.).

[0054] The second connecting hole 132 is vertically positioned through the first mounting base 12, allowing the oil discharged from the oil filter to be delivered to the cylinder block side located above the oil pan 10. It is understood that the second connecting hole 132 can communicate with an oil passage formed on the cylinder block side, and the end of the second connecting hole 132 communicating with the oil passage is located inside the housing body 1, so that after the oil pan 10 is connected to the cylinder block, the communication position between the second connecting hole 132 and the oil passage in the cylinder block is formed in a closed environment.

[0055] like Figure 1 As shown, in some embodiments of this application, a third connecting hole 133 is also provided at the second mounting base 13, and the third connecting hole 133 is used to communicate and cooperate with the oil supply pump in the pump assembly described above.

[0056] One end of the third connecting hole 133 is located inside the housing body 1 and is used to connect with the oil supply pump. The other end of the third connecting hole 133 is open at the second mounting base 13 facing outward in the second direction (i.e., away from the housing body 1) and is used to connect with the oil cooler. Thus, the oil supplied to the third connecting hole 133 by the oil supply pump can flow into the oil cooler through the third connecting hole 133 to achieve cooling of the oil.

[0057] Reference Figure 1 As shown, the mating path between the lubricating medium and the oil pan 10 in the lubrication system according to this application is described: The oil is delivered by the pump assembly. The oil flows into the oil cooler through the third connecting hole 133. After flowing through the oil cooler, the oil flows into the oil filter through the first connecting hole 131 (at this time, the oil has been cooled down by the oil cooler). The oil filtered by the oil filter is delivered to the oil passage on the cylinder block side of the engine through the second connecting hole 132.

[0058] Thus, the oil pan 10, oil cooler, and oil filter work together to cool and filter the engine oil. Furthermore, the connecting structure (i.e., the multiple connecting holes mentioned above) can be integrated into the oil pan 10, saving on the number of pipes in the engine and shortening the oil circulation path in the engine. Moreover, the compact arrangement of the oil cooler and oil filter can improve the cooling and filtration efficiency of the lubrication system in the engine.

[0059] like Figure 1 As shown in some embodiments of this application, the bottom wall of the shell body 1 has a first guide surface 141 and a second guide surface 142. The first guide surface 141 and the second guide surface 142 are respectively disposed on both sides of the settling tank 11 in a second direction. The first guide surface 141 extends downward in the second direction to the open end of the settling tank 11, and the second guide surface 142 also extends downward in the second direction to the open end of the settling tank 11. As a result, the engine oil in the receiving tank 101 can preferentially converge to the settling tank 11 under the guiding action of the first guide surface 141 and the second guide surface 142, thereby better realizing the centralized storage of engine oil.

[0060] Understandably, the receiving trough 101 is vertically open to the upward side (i.e., the cylinder side). Oil flowing into the receiving trough 101 from the cylinder side is directed towards the sink 11 by the first guide surface 141 and the second guide surface 142, thus ensuring effective oil extraction from the oil pan 10. Even if the amount of oil in the oil pan 10 is small, the smaller amount will preferentially accumulate in the sink 11, facilitating oil extraction from the sink 11 through the suction port 102.

[0061] Combination Figure 1 and Figure 2 As shown, in some embodiments of this application, at least one of the first guide surface 141 and the second guide surface 142 is provided with a rib 15, and the rib 15 protrudes into the inner side of the receiving groove 101, so as to improve the structural strength of the first guide surface 141 and the second guide surface 142 through the rib 15, and avoid the problem of insufficient strength due to the first guide surface 141 and the second guide surface 142 being constructed as large-sized planar structures.

[0062] The fact that at least one of the first guide surface 141 and the second guide surface 142 is provided with a rib 15 means that: a rib 15 may be provided only on the first guide surface 141; a rib 15 may be provided only on the second guide surface 142; or a rib 15 may be provided on both the first guide surface 141 and the second guide surface 142.

[0063] In some embodiments of this application, in the projection in the vertical direction, the rib 15 extends along the second direction, so that the rib 15 can guide the flow direction of the oil, making it easier for the oil to flow quickly into the settling tank 11.

[0064] Understandably, the ribs 15 protrude from the guide surface (e.g., the first guide surface 141) toward the inner side of the receiving groove 101, defining a channel for oil flow between two adjacent ribs 15 in the first direction, allowing the oil to flow quickly into the settling tank 11 for centralized oil storage. The ribs 15 extend from the side wall of the housing body 1 to the open end of the settling tank 11.

[0065] like Figure 1 As shown, in some embodiments of this application, the settling tank 11 is provided with a plurality of oil suction ports 102. The plurality of oil suction ports 102 are arranged at intervals along the first direction in the settling tank 11, so as to ensure the oil extraction effect in the settling tank 11 by setting a plurality of oil suction ports 102, and avoid the problem of air suction caused by oil sloshing.

[0066] It should be noted that the oil pan 10 in this application can be used in engines with dry lubrication systems. In dry lubrication systems, the amount of oil inside the oil pan 10 is very small. The oil collector needs to quickly pump the oil splashed from the crankshaft to an independent oil tank (such as an oil can). Moreover, the vehicle's operating conditions (rapid acceleration / rapid deceleration) will further affect the oil suction stability of the collector, and may even cause serious failures such as engine cylinder scoring and bearing seizure.

[0067] The aforementioned "cylinder scoring" refers to the appearance of obvious longitudinal mechanical scratches or abrasions on the inner wall of the engine cylinder within the movement range of the piston rings. In severe cases, this can lead to fused wear (i.e., metal adhesion), resulting in a loss of cylinder sealing. The aforementioned "bearing seizure" refers to the melting and adhesion of metal surfaces between the engine's internal shafts (such as the crankshaft and connecting rod shaft) and bearings due to poor lubrication or abnormal clearance, preventing normal operation. Both of these faults can be caused by insufficient engine lubrication.

[0068] In this application, by providing multiple oil suction ports 102 at the settling tank 11, the pump assembly (i.e., the oil suction device) is able to draw oil from the settling tank 11 from the multiple oil suction ports 102.

[0069] When the first direction is parallel to the X-direction of the vehicle, the multiple oil suction ports 102 in the trough 11 are arranged at intervals in the front-to-back direction. Furthermore, when the vehicle is in conditions such as acceleration, deceleration, climbing, or descending, the oil in the oil pan 10 will flow to the front or rear side, and the pump assembly can still draw oil through at least one oil suction port 102.

[0070] Specifically, when the vehicle is accelerating or climbing, the oil in the oil pan 10 will flow to the rear, and the oil can be drawn through the rear oil suction port 102 among the multiple oil suction ports 102; when the vehicle is decelerating or going downhill, the oil in the oil pan 10 will flow to the front, and the oil can be drawn through the front oil suction port 102 among the multiple oil suction ports 102.

[0071] Understandably, the two side walls of the sink 11 in the second direction also restrain the engine oil, thus preventing the engine oil from flowing out of the sink 11 when the vehicle turns left or right, ensuring the oil storage effect of the sink 11. This ensures that the engine's lubrication system can continuously return oil.

[0072] like Figure 2 As shown, in some embodiments of this application, an oil drain port is provided in the oil pan 10, and a screw plug 16 is provided at the oil drain port. The screw plug 16 is threadedly engaged with the oil drain port, and a washer 17 can be provided between the screw plug 16 and the bottom wall of the oil pan 10 to ensure the reliability of the connection between the screw plug 16 and the oil pan 10.

[0073] Furthermore, the oil drain port is located at the bottom wall of the settling tank 11, which ensures the oil draining effect at the drain port. When the oil needs to be changed, the oil in the oil pan 10 can be fully drained from the drain port.

[0074] like Figure 2 As shown, in some embodiments of this application, the shell body 1 is provided with a reinforcing rib 18, which is located at the bottom of the shell body 1 and on the side of the bottom wall of the shell body 1 away from the receiving groove 101, so as to improve the structural strength of the shell body 1 through the reinforcing rib 18.

[0075] Combination Figure 1 and Figure 2 As shown, the reinforcing ribs 18 on the shell body 1 can be connected and cooperate with the first mounting base 12 and the second connecting base 13 respectively to improve the structural strength at the joint between the first mounting base 12 and the second mounting base 13.

[0076] It should be noted that the location and extension method of the reinforcing rib 18 on the shell body 1 are not specifically limited here, and can be adapted to the strength requirements of the shell body 1.

[0077] According to the oil pan 10 of this application embodiment, the oil pan 10 can preferentially collect the engine oil in the sink 11, and the sink 11 is provided with multiple oil suction ports 102, so that the pump assembly can draw the engine oil through the multiple oil suction ports 102 respectively, so as to ensure the stability of the oil extraction under various working conditions (such as acceleration, deceleration, climbing, descending, etc.).
