[0024] Figure 1 The structure of the oil sump provided by the present application is illustrated. Referring to Figure 1 , the oil sump provided by the present application comprises an oil sump body 100, a first end inside the oil sump body 100 has a shallow oil area 110, a second end inside the oil sump body 100 has a deep oil area 120; the bottom of the shallow oil area 110 is provided with a plurality of wave breakers 200, the plurality of wave breakers 200 are arranged along the length direction of the shallow oil area 110, and the wave breakers 200 are used to block the flow of fluid inside the shallow oil area 110.
[0025] It should be noted that the shallow oil area 110 and the deep oil area 120 are in communication with each other, and the depth of the deep oil area 120 is greater than the depth of the shallow oil area 110. The first end inside the oil sump body 100 is Figure 1 implemented as the upper end of the oil sump body 100, and the same, the second end inside the oil sump body 100 is the lower end. The length direction of the oil sump body 100 is arranged along the up-down direction as shown in Figure 1 , and the length of the shallow oil area 110 and the deep oil area 120 is also arranged along the up-down direction. Figure 1
[0026] The present application arranges a plurality of wave breakers 200 arranged along the length direction at the bottom of the shallow oil area 110, the wave breakers 200 can play a physical blocking role, when the oil is affected by the vehicle action and tries to move quickly, the wave breakers 200 will hinder the fluid from one area to another area, thereby effectively reducing the speed and intensity of the oil flow, reducing the impact force on the oil sump wall and the connecting part. By such arrangement, not only the stability and reliability of the engine during operation are improved, but also the service life of the oil sump and its related components (such as the engine foot) is prolonged, and the leakage risk is reduced.
[0027] In some possible embodiments, the specific shape, size and layout of the wave breaker 200 can be fine-tuned through fluid dynamics simulation analysis, such as using different heights in staggered arrangement or setting specific angles to more effectively disperse and weaken the flow energy. Secondly, vibration-absorbing materials such as special rubber pads can be used at appropriate positions inside the oil pan, which have good buffering effect and can absorb a certain amount of energy transmitted by oil fluctuations, reducing the impact of vibration on the oil pan itself. Furthermore, pressure sensors, temperature sensors and other monitoring devices can be installed at key positions of the oil pan to collect and analyze data in real time, and once abnormal conditions are found, the driver will be alerted to check and maintain, preventing potential failures.
[0028] The oil pan body 100 can be made of PA66 (Nylon 66) + GF35 (35% glass fiber) engineering plastic. The use of PA66 + GF35 engineering plastic for the oil pan body 100 has the following advantages:
[0029] ① High strength and rigidity: The addition of 35% glass fiber significantly improves the basic mechanical properties of PA66, making it have higher tensile strength, bending modulus and impact resistance, capable of withstanding various stresses during engine operation.
[0030] ② Lightweight: Compared with traditional metal materials such as aluminum alloy or steel, PA66 + GF35 composite material has lower density, which helps to reduce the weight of the engine, thereby improving fuel efficiency and reducing emissions.
[0031] ③ Good dimensional stability: The addition of glass fiber enhances the material's resistance to thermal deformation, ensuring stable shape and size even in high temperature environments, which is crucial for maintaining sealing and preventing leaks.
[0032] ④ Excellent chemical resistance: PA66 itself has good resistance to many chemicals, and after adding glass fiber, the overall material is more durable and less susceptible to erosion by engine oil and other lubricants.
[0033] ⑤ Easy to mold and process: The material can be quickly and efficiently produced into complex shaped parts through processes such as injection molding, which is beneficial for design innovation and cost-effectiveness.
[0034] ⑥ Reduce noise and vibration transmission: Compared with metal materials, plastic has better sound insulation effect and can absorb part of the vibration energy, which helps to improve the driving comfort.
[0035] Referring to Figure 1In some embodiments of the utility model, the wave guard 200 is symmetrically distributed along the width direction of the shallow oil area 110 into two groups, and the multiple wave guards 200 in each group are arranged at intervals along the length direction of the shallow oil area 110. The specific number of wave guards 200 can be six, and the six wave guards 200 are symmetrically arranged into two groups, and the size of the wave guard 200 in each group can be different, but the size of the two wave guards 200 symmetrically arranged in the two groups is the same. A gap is arranged between the two groups of wave guards 200 to facilitate the circulation of oil.
[0036] In the embodiment, the two groups of wave guards are symmetrically arranged along the width direction of the shallow oil area 110, which can uniformly disperse the impact force of the oil in the horizontal direction and effectively avoid the imbalance phenomenon caused by excessive force on one side. The multiple wave guards in each group are arranged at intervals along the length direction of the shallow oil area 110, forming a multi-stage damping structure, gradually slowing down the flow speed of the oil, thereby significantly reducing the fluctuation amplitude and impact force. In addition, the length of the wave guard gradually increases from the end far away from the deep oil area 120 to the end close to the deep oil area 120, which not only further weakens the kinetic energy of the oil, but also better controls the flow state of the oil under different driving conditions, ensuring that all parts of the engine are always fully lubricated. In addition, this progressive layout reduces the direct impact of the oil on the inner wall of the oil pan and the connecting part, reduces the risk of fatigue damage caused by long-term vibration, and prolongs the service life of the entire system.
[0037] Referring to Figure 1 In some embodiments of the utility model, the wave guard 200 comprises an integrated setting part 210 and a wave guard part 220, the setting part 210 is integrated on the side wall of the shallow oil area 110, that is, the setting part 210 is integrally formed with the shallow oil area 110. The wave guard part 220 is located on the side of the setting part 210 away from the side wall of the shallow oil area 110, the wave guard part 220 is arranged at an angle with the side wall of the shallow oil area 110, and the bottom of the wave guard part 220 is fixed to the bottom wall of the shallow oil area 110, so that the connection between the wave guard 200 and the shallow oil area 110 is more closely and better cope with the impact of the oil. The side of the wave guard part 220 facing the deep oil area 120 is concave, and the side of the wave guard part 220 away from the deep oil area 120 is convex.
[0038] In the embodiment, the setting part 210 is fixed on the side wall of the shallow oil area 110, ensuring the stability of the structure, and the wave guard part 220 is arranged on the side away from the side wall and forms an angle with the side wall, which effectively guides and controls the flow of the oil and can guide the oil.
[0039] The side of the wave-preventing part 220 facing the deep oil area 120 is designed as a concave surface, which can better capture and disperse the impact force of the oil liquid and slow down its flow to the deep oil area 120; the side of the wave-preventing part 220 facing away from the deep oil area 120 is a convex surface, which helps to further disperse the kinetic energy of the oil liquid and reduce the direct impact on the side wall. This design not only effectively suppresses the fluctuation of the oil liquid, but also promotes the uniform distribution of the oil liquid in the oil pan, improving the lubrication efficiency. In addition, due to the special angle and curved surface design of the wave-preventing part 220, it can maintain good working performance under different driving conditions, whether it is smooth driving or extreme conditions such as sudden acceleration and sudden braking, it can provide consistent and reliable oil management effect.
[0040] Reference Figure 1 In some embodiments of the present application, the outer side wall of the shallow oil area 110 is integrally formed with a first protruding part 400, and the first protruding part 400 is provided with a first integrated interface 410 communicating with the shallow oil area 110. The outer side wall of the deep oil area 120 is integrally formed with a second protruding part 500 and a third protruding part 600, and the second protruding part 500 and the third protruding part 600 are arranged in a spaced manner, the second protruding part 500 is provided with a second integrated interface 510 communicating with the deep oil area 120, and the third protruding part 600 is provided with a third integrated interface 610 communicating with the deep oil area 120.
[0041] The present embodiment has many advantages by integrally forming protruding parts on the outer side walls of the shallow oil area 110 and the deep oil area 120, and opening integrated interfaces on these protruding parts. First, the first protruding part 400 on the outer side wall of the shallow oil area 110 is provided with the first integrated interface 410 communicating with the shallow oil area 110, while the second protruding part 500 and the third protruding part 600 are provided on the outer side wall of the deep oil area 120, respectively equipped with the second integrated interface 510 and the third integrated interface 610. Such a layout not only enhances the overall structural strength of the oil pan, but also optimizes the oil flow path.
[0042] In addition, the design of the protruding part increases the effective volume of the oil pan, which helps to better collect and store engine oil, especially in the case of vehicle inclination or severe driving, to ensure that the engine is always supplied with sufficient lubricating oil. At the same time, the combination of the protruding part and the integrated interface makes the oil liquid flow more smoothly between different areas, further improving the overall performance and reliability of the lubrication system.
[0043] Specifically, the first integrated interface 410 can be used to install an oil level gauge or sensor, facilitating the monitoring of oil quantity and quality; the second integrated interface 510 can be used to connect an oil filter, ensuring that the oil is fully filtered before entering the engine, thereby maintaining cleanliness; and the third integrated interface 610 can serve as an integrated return oil pipe interface, which is used to redirect used oil discharged from various engine components such as valve covers and turbochargers back to the oil pan. Through the dedicated integrated interfaces, it can be ensured that these oils return smoothly to the oil pan, thereby optimizing the entire oil circulation system.
[0044] Referring to Figure 1 In some embodiments of the present application, the deep oil area 120 is integrally formed with an oil suction pipe assembly 800 inside. The bottom of the deep oil area 120 is also provided with a drain bolt 700.
[0045] In this embodiment, the oil suction pipe assembly 800 is integrally formed inside the deep oil area 120, ensuring the stability and durability of the structure, and reducing the risk of oil leakage due to loose or damaged connecting parts. The oil suction pipe assembly 800 is directly located inside the deep oil area 120, which can more effectively extract engine oil, ensuring stable oil supply even in the case of vehicle inclination or low oil level, thereby improving the reliability of the engine lubrication system. In addition, the integration of the oil suction pipe assembly 800 with the oil pan simplifies the manufacturing and assembly process, reduces production costs, and improves the compactness and aesthetics of the overall structure.
[0046] At the same time, the drain bolt 700 is provided at the bottom of the deep oil area 120, providing convenience for oil replacement. The position of the drain bolt 700 allows old oil to be smoothly drained, reducing residual amount and ensuring the purity of new oil, which helps to prolong the service life of the engine. In addition, the design of the drain bolt 700 facilitates regular maintenance, is simple and fast to operate, and improves maintenance efficiency.
[0047] Referring to Figure 1 In some embodiments of the present application, the top of the oil pan body 100 is provided with a sealing gasket groove, and the sealing gasket groove is internally provided with a sealing element 300.
[0048] In this embodiment, the design of the sealing gasket groove provides the sealing element 300 with precise position and fixing space, ensuring that the sealing element 300 can tightly fit between the oil pan and the engine cylinder, thereby forming a reliable sealing interface. This not only effectively prevents oil leakage, but also enhances the sealing performance of the entire system. In addition, the presence of the sealing gasket groove makes the installation of the sealing element 300 more convenient and accurate, reducing the risk of leakage due to improper installation. The sealing element 300 is firmly embedded in the groove and is not easily displaced or fallen off, even in the case of long-term operation or vibration of the engine, it can maintain good sealing effect, prolonging the service life of the sealing element 300.
[0049] Reference Figure 1 In some embodiments of the present application, the outer wall of the oil pan body 100 is provided with a reinforcing rib 130.
[0050] This embodiment sets a reinforcing rib 130 on the outer wall of the oil pan body 100, which brings many advantages. First, the reinforcing rib 130 significantly enhances the overall structural strength and rigidity of the oil pan, enabling it to better resist external impact and internal oil fluctuations, thereby improving the durability and reliability of the oil pan.
[0051] In addition, the design of the reinforcing rib 130 helps to disperse the vibrations and impact forces generated by the engine during operation, reducing the deformation or fatigue damage that may occur to the oil pan due to long-term stress. This not only prolongs the service life of the oil pan, but also ensures its stable performance under various driving conditions. By increasing the structural rigidity, the reinforcing rib 130 also effectively prevents the oil pan from deforming under extreme conditions such as high-speed driving, sudden acceleration or sudden braking, ensuring uniform distribution of oil in the oil pan, thereby improving the efficiency and stability of the lubrication system.
[0052] In addition, the reinforcing rib 130 also helps to improve the thermal stability of the oil pan by increasing the heat dissipation area, which helps to more effectively dissipate the heat generated during engine operation, keeping the oil temperature within a reasonable range and further protecting the internal components of the engine.
[0053] The present application also provides an engine comprising the oil pan of any one of the above embodiments.
