[0028] The following will be combined with Figure 1 and Figure 2 to describe in detail the oil sump assembly 10, the engine and the vehicle according to the embodiments of the present utility model.

[0029] Refer to Figure 1 and Figure 2As shown in the figure, the oil pan assembly 10 according to an embodiment of the present invention includes an oil pan 1, an oil baffle 2, and an oil collector 3. The oil pan 1 forms an oil cavity. The oil baffle 2 is fixedly arranged in the oil cavity. The oil baffle 2 divides the oil cavity into an oil collecting space and an oil storage space. The oil collecting space is located above the oil storage space. The oil baffle 2 has a communication hole 21. The oil collecting space is communicated with the oil storage space through the communication hole 21. The oil collector 3 penetrates through the oil baffle 2, and the oil suction port of the oil collector 3 is located in the oil storage space.

[0030] Among them, the oil pan 1 is adapted to be fixedly connected to the bottom of the engine block. The oil collector 3 can suck the oil in the oil storage space through the oil suction port, and can send the sucked oil into the oil passage of the engine block through the oil outlet of the oil collector 3. The oil can flow through the oil passage of the block to the components in the engine (for example, the crankshaft, piston, etc.) to lubricate the components in the engine, reduce the wear of the components, and thus is beneficial to the stable and reliable operation of the engine. The oil after participating in lubrication can fall into the oil collecting space of the oil pan 1 under the action of gravity, and can flow into the oil storage space through the communication hole 21 on the oil baffle 2 to realize oil return, ensure that there is sufficient oil in the oil storage space, and thus is beneficial to reducing the risk of oil suction void. At the same time, the oil baffle 2 can also prevent the oil splashing at high speed from directly falling into the oil storage space to avoid the generation of bubbles in the oil in the oil storage space, and thus is beneficial to ensuring the lubrication performance of the oil.

[0031] It can be understood that the oil baffle 2 divides the oil cavity into an oil collecting space and an oil storage space. When the vehicle accelerates, decelerates or tilts, the oil in the oil storage space will tilt under the action of inertia or gravity. The oil baffle 2 can prevent the oil in the oil storage space from flowing into the oil collecting space, reduce the amount of oil flowing from the oil storage space into the oil collecting space, ensure that there is sufficient oil in the oil storage space, and is beneficial to keeping the oil suction port of the oil collector 3 below the oil level in the oil storage space, keeping the oil collector 3 in a state where it can suck oil, and effectively reducing the risk of oil suction void.

[0032] For the oil pan assembly 10 according to an embodiment of the present invention, its oil baffle 2 divides the oil cavity of the oil pan 1 into an oil collecting space and an oil storage space. The oil collecting space is located above the oil storage space. The oil baffle 2 can prevent the oil in the oil storage space from flowing into the oil collecting space to ensure that there is sufficient oil in the oil storage space, and is beneficial to keeping the oil suction port of the oil collector 3 below the oil level in the oil storage space, and thus is beneficial to reducing the risk of oil suction void.

[0033] In some embodiments of the present invention, refer to Figure 2As shown, the number of the communication holes 21 is multiple, and the engine oil in the oil collecting space can smoothly flow into the oil storage space through the multiple communication holes 21, so as to supplement the engine oil in the oil storage space in time, avoid the accumulation of engine oil in the oil collecting space, ensure that the engine oil quantity in the oil storage space is sufficient, and thus is beneficial to further reducing the risk of oil suction void.

[0034] In some embodiments of the present utility model, the flow area of the communication hole 21 is less than or equal to 100 cm 2 , for example, the flow area of the communication hole 21 can be 50 cm 2 , 80 cm 2 , 100 cm 2 etc., which is beneficial to reducing the amount of oil flowing from the oil storage space to the oil collecting space, ensuring that the oil quantity in the oil storage space is sufficient, being beneficial to keeping the oil suction port of the oil collector 3 below the liquid level of the engine oil, and thus being beneficial to further reducing the risk of oil suction void.

[0035] It can be understood that if the flow area of the communication hole 21 is greater than 100 cm 2 , the flow area of the communication hole 21 is relatively large. When the vehicle accelerates, decelerates or tilts, the engine oil in the oil storage space will tilt under the action of inertia or gravity, and a large amount of the engine oil in the oil storage space can flow into the oil collecting space through the communication hole 21 with a large flow area, resulting in a large reduction in the amount of engine oil in the oil storage space, easily causing the oil suction port of the oil collector 3 to be above the liquid level of the engine oil, and the risk of oil suction void is relatively large.

[0036] In this embodiment, the flow area of the communication hole 21 is less than or equal to 100 cm 2 , the flow area of the communication hole 21 is relatively small, which can reduce the flow rate of the engine oil in the oil storage space flowing through the communication hole 21 to the oil collecting space, ensure the engine oil quantity in the oil storage space, and thus is beneficial to reducing the risk of the oil collector 3 sucking void of the engine oil, and is beneficial to the stable and reliable operation of the engine.

[0037] In some embodiments of the present utility model, referring to Figure 1 and 2 as shown, the baffle 2 has fixing holes 22, the oil collector 3 passes through the baffle 2 at the fixing holes 22, and the oil collector 3 is fixedly connected to the fixing holes 22, so as to improve the stability of the oil collector 3, avoid the shaking of the oil collector 3 during the working process, ensure that the oil collector 3 is always in a state where it can suck the engine oil, and is beneficial to further reducing the risk of oil suction void. Among them, the oil collector 3 can be fixedly connected to the fixing holes 22 by connection means such as fastener connection, threaded connection, snap connection, etc.

[0038] In some embodiments of the present utility model, referring to Figure 2As shown, the fixing hole 22 and the communication hole 21 have different shapes to facilitate the distinction between the fixing hole 22 and the communication hole 21. When installing the oil collector 3 into the fixing hole 22, the fixing hole 22 can be quickly identified and positioned, so as to quickly and accurately install the oil collector 3 into the fixing hole 22, which is beneficial to improving the assembly efficiency of the oil pan assembly 10 and can effectively prevent the oil collector 3 from being installed at the wrong position, so as to achieve the anti-fooling effect.

[0039] In some embodiments of the present invention, refer to Figure 2 As shown, the fixing hole 22 is a circular hole, and the communication hole 21 is a rectangular hole. The fixing hole 22 and the communication hole 21 have different shapes to facilitate the quick identification of the fixing hole 22 and the communication hole 21, which is beneficial to quickly and accurately install the oil collector 3 into the fixing hole 22, thereby improving the assembly efficiency of the oil pan assembly 10.

[0040] In addition, the fixing hole 22 being a circular hole is beneficial to realizing the threaded connection between the fixing hole 22 and the oil collector 3. Specifically, internal threads can be machined on the inner peripheral wall of the fixing hole 22, and external threads can be machined on the outer peripheral wall of the oil collector 3. The external threads of the oil collector 3 are adapted to be threadedly engaged with the internal threads of the fixing hole 22 to enable the threaded connection between the fixing hole 22 and the oil collector 3.

[0041] In some embodiments of the present invention, refer to Figure 1 As shown, the oil pan 1 includes: an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are detachably connected and jointly define an oil chamber. The oil baffle 2 is fixedly connected to the upper housing 11, which is beneficial to the integration of the oil pan assembly 10. Among them, the upper housing 11 and the lower housing 12 can be detachably connected by fasteners. The fasteners can be screws, bolts, nuts, etc. The upper housing 11 and the oil baffle 2 can jointly define an oil collection space, and the lower housing 12 and the oil baffle 2 can jointly define an oil storage space.

[0042] It can be understood that the upper housing 11 and the lower housing 12 are detachably connected, and the upper housing 11 and the lower housing 12 can be integrally formed, which is beneficial to reducing the manufacturing difficulty of the upper housing 11 and the lower housing 12, facilitating the production and manufacturing of the oil pan 1. In addition, when assembling the oil pan assembly 10, the oil collector 3 can be first installed on the oil baffle 2 fixedly connected to the upper housing 11, and then the lower housing 12 can be installed on the upper housing 11. The installation of the oil collector 3 is not interfered by the lower housing 12, and there is a large operating space, which is convenient for the installation of the oil collector 3, thus being beneficial to the assembly of the oil pan assembly 10. In addition, when the oil collector 3 needs to be maintained, the lower housing 12 can be removed from the upper housing 11, which is convenient for maintaining the oil collector 3.

[0043] In some embodiments of the present invention, refer to Figure 2As shown, the oil baffle plate 2 is integrally formed with the upper shell 11, and the oil baffle plate 2 and the upper shell 11 do not need to be connected by fasteners or welding, which is beneficial to reducing the assembly steps of the oil baffle plate 2 and the upper shell 11, thereby helping to improve the production efficiency of the oil pan assembly 10. At the same time, it is also beneficial to reduce the number of parts of the oil pan assembly 10 and reduce the production cost of the oil pan assembly 10.

[0044] In other embodiments of the utility model, the oil baffle plate 2 and the upper shell 11 are formed separately, and the oil baffle plate 2 and the upper shell 11 can be manufactured separately, which is beneficial to reduce the manufacturing difficulty of the oil baffle plate 2 and the upper shell 11, so as to facilitate the production of the oil pan assembly 10.

[0045] In some embodiments not shown in the figures of the present utility model, the oil pan assembly 10 may further include an adjustment plate, a driver and a controller. The adjustment plate is slidably connected to the oil baffle plate 2. The driver is used to drive the adjustment plate to slide to a first preset position and a second preset position. When the adjustment plate is in the first preset position, the adjustment plate blocks the connecting hole 21. When the adjustment plate is in the second preset position, the adjustment plate and the connecting hole 21 are staggered. The controller is used to obtain the inclination angle of the oil pan assembly 10. When the inclination angle is greater than or equal to a preset threshold, the controller controls the driver to drive the adjustment plate to slide to the first preset position so that the adjustment plate blocks the connecting hole 21. Reducing the flow rate of the oil in the oil storage space into the oil collecting space through the connecting hole 21 to ensure that the amount of oil in the oil storage space is sufficient is beneficial to keeping the oil suction port of the oil collector 3 below the liquid level of the oil in the oil storage space, which can effectively reduce the risk of oil vacuum. When the tilt angle is less than the preset threshold, the controller controls the driver to drive the adjustment plate to slide to the second preset position to stagger the adjustment plate and the connecting hole 21, so that the oil in the oil collecting space can flow into the oil storage space through the connecting hole 21, so as to replenish the oil in time and ensure the amount of oil in the oil storage space, which is beneficial to reduce the risk of oil vacuum.

[0046] In some embodiments of the utility model not shown in the figures, the aperture of the connecting hole 21 gradually decreases in the direction from the upper shell 11 to the lower shell 12, that is, the aperture of the connecting hole 21 on the side close to the upper shell 11 is larger than the aperture of the connecting hole 21 on the side close to the lower shell 12. The connecting hole 21 can be constructed in a bell-mouth shape. The aperture of the connecting hole 21 on the side close to the upper shell 11 is larger, so that the oil in the oil collecting space can flow into the oil storage space through the connecting hole 21, and the aperture of the connecting hole 21 on the side close to the lower shell 12 is smaller, so that the oil in the oil storage space is difficult to flow into the oil collecting space, thereby ensuring the amount of oil in the oil storage space, which is beneficial to reducing the risk of oil absorption. In addition, the inner side wall of the bell-mouth-shaped connecting hole 21 is an inclined surface, which can guide the oil in the oil collecting space to flow into the oil storage space, so that the oil in the oil collecting space can flow smoothly to the oil storage space.

[0047] In embodiments not shown in some of the figures of the present utility model, the oil pan assembly 10 may further include a one-way valve. The one-way valve is provided in the communication hole 21 and conducts unidirectionally in the direction from the upper housing 11 to the lower housing 12. The one-way valve can prevent the engine oil in the oil storage space from flowing into the oil collection space, effectively ensuring the amount of engine oil in the oil storage space, which is beneficial to reducing the risk of oil suction void. At the same time, the engine oil in the oil collection space can flow into the oil storage space through the one-way valve to supplement the engine oil in the oil storage space, ensuring the amount of engine oil in the oil storage space, thereby being beneficial to reducing the risk of oil suction void.

[0048] In some embodiments of the present utility model, with reference to Figure 1 as shown, the upper housing 11 is configured in an "L" shape. In the up-down direction, the cross-sectional area of the upper part of the upper housing 11 is larger than that of the lower part of the upper housing 11. The larger cross-sectional area of the upper part of the upper housing 11 is convenient for receiving engine oil, and the smaller cross-sectional area of the lower part of the upper housing 11 can avoid interference between the upper housing 11 and the subframe of the vehicle.

[0050] For the engine according to the embodiment of the present utility model, the baffle 2 of its oil pan assembly 10 divides the oil chamber of the oil pan 1 into an oil collection space and an oil storage space. The oil collection space is located above the oil storage space. The baffle 2 can prevent the engine oil in the oil storage space from flowing into the oil collection space to ensure that there is sufficient engine oil in the oil storage space, which is beneficial to keeping the oil suction port of the oil collector 3 below the liquid level of the engine oil in the oil storage space, thereby being beneficial to reducing the risk of oil suction void.
