[0051] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a vehicle 100 provided in an embodiment of this application. The vehicle 100 can be a pure electric vehicle 100, a hybrid electric vehicle 100, a plug-in hybrid electric vehicle 100, a range-extended electric vehicle 100, a gasoline-powered vehicle, etc. The vehicle 100 can also be a sedan, truck, bus, lorry, trailer, etc. This application does not specifically limit the type of vehicle 100.

[0052] Please see Figures 2 to 7 The present invention provides an oil reservoir assembly 10 for use in a vehicle 100. The oil reservoir assembly 10 includes a first oil reservoir 2, which is adapted to store lubricating oil and is adapted to be connected to the engine 30 of the vehicle 100.

[0053] Along the length of the vehicle 100, the first oil reservoir 2 is preferably located between the engine 30 and the front end of the vehicle 100, and the distance between the first oil reservoir 2 and the exhaust pipe 31 of the engine 30 is not less than 500mm. For example, the distance between the first oil reservoir 2 and the exhaust pipe 31 of the engine 30 can be 500mm, 505mm, 510mm, 515mm, 520mm, 525mm, 530mm, 535mm, or 540mm.

[0054] In the oil reservoir assembly 10 of this application embodiment, the oil reservoir assembly 10 is applied to a vehicle 100. The oil reservoir assembly 10 includes a first oil reservoir 2, which is adapted to store lubricating oil and is adapted to connect to the engine 30 of the vehicle 100. Along the length direction of the vehicle 100, the first oil reservoir 2 is adapted to be located between the engine 30 and the front end of the vehicle 100, and the distance between the first oil reservoir 2 and the exhaust pipe 31 of the engine 30 is not less than 500 mm. Thus, when the vehicle 100 is involved in a collision, because the distance between the first oil reservoir 2 and the exhaust pipe 31 of the engine 30 is greater than or equal to 500 mm, the distance between the first oil reservoir 2 and the exhaust pipe 31 of the engine 30 is relatively large, preventing the oil from the first oil reservoir 2 from splashing onto the engine 30, thereby preventing accidental fire.

[0055] In some embodiments, the distance from the first oil reservoir 2 to the exhaust pipe 31 along the height direction of the vehicle 100 is not less than 450mm. For example, the distance from the first oil reservoir 2 to the exhaust pipe 31 along the height direction of the vehicle 100 can be 450mm, 455mm, 460mm, 465mm, 470mm, etc.

[0056] Thus, the first oil reservoir 2 is relatively far from the exhaust pipe 31 in the vertical direction. In other words, the position of the first oil reservoir 2 is much lower than the position of the engine 30 body. When the first oil reservoir 2 is impacted and ruptures, the engine oil is less likely to splash onto the top of the engine 30 and cause the engine 30 to catch fire. In this way, when the vehicle 100 is involved in a collision, the core components such as the engine 30 are less likely to be damaged, and the safety of the vehicle 100 is improved.

[0057] In some embodiments, the first oil reservoir 2 includes a gas-liquid separation structure 11 and an oil storage structure 12. The oil inlet end 111 and the exhaust end 112 of the gas-liquid separation structure 11 are adapted to be connected to the engine 30, and the oil storage structure 12 is connected to the oil outlet end 115 of the gas-liquid separation structure 11.

[0058] In this way, the first oil reservoir 2 can both store oil and separate the oil from the gas through the gas-liquid separator 11 before delivering it to the engine 30.

[0059] In some embodiments, the oil can assembly 10 further includes a second oil can 1 connected to the first oil can 2. The second oil can 1 is adapted to be connected to the engine 30 of the vehicle 100. Along the length direction of the vehicle 100, the second oil can 1 is adapted to be disposed between the first oil can 2 and the engine 30.

[0060] In some embodiments, the internal structures of the first oil reservoir 2 and the second oil reservoir 1 are similar, both including a gas-liquid separation structure 11 and an oil storage structure 12.

[0061] In some embodiments, the storage capacity of the second oil container 1 is less than that of the first oil container 2.

[0062] In some embodiments, the second oil reservoir 1 is capable of gas-liquid separation of the oil-gas mixture of the engine 30; the first oil reservoir 2 is used to supply engine oil to the engine 30.

[0063] In the oil reservoir assembly 10 of this application embodiment, the oil reservoir assembly 10 includes a second oil reservoir 1 and a first oil reservoir 2. Along the length direction of the vehicle 100, the second oil reservoir 1 is adapted to be disposed between the engine 30 and the front end of the vehicle 100, and the first oil reservoir 2 is adapted to be closer to the front end of the vehicle 100 than the second oil reservoir 1. That is, both the second oil reservoir 1 and the first oil reservoir 2 are disposed between the engine 30 and the front end of the vehicle 100, but the first oil reservoir 2 is farther away from the engine 30 of the vehicle 100 than the second oil reservoir 1. Thus, when the vehicle 100 is hit by a collision, the first oil reservoir 2 is hit first, and since the first oil reservoir 2 is farther away from the engine 30, the risk of oil in the first oil reservoir 2 splashing onto the engine 30 when the first oil reservoir 2 is hit can be reduced or avoided. At the same time, the impact on the second oil reservoir 1 is greatly reduced, thus avoiding the risk of oil in the oil reservoir assembly 10 splashing onto the engine 30 and exhaust pipe 31 when the vehicle 100 is hit by a collision, which could lead to an abnormal fire in the vehicle 100.

[0064] In some embodiments, the second oil reservoir 1 and / or the first oil reservoir 2 are capable of performing gas-liquid separation on the oil-gas mixture of the engine 30.

[0065] Specifically, the second oil reservoir 1 can perform gas-liquid separation of the oil-gas mixture in the engine 30, or the first oil reservoir 2 can perform gas-liquid separation of the oil-gas mixture in the engine 30, or both the second oil reservoir 1 and the first oil reservoir 2 can perform gas-liquid separation of the oil-gas mixture in the engine 30.

[0066] Thus, the oil can assembly 10 is divided into a second oil can 1 and a first oil can 2. The second oil can 1 and the first oil can 2 each have their own functions, and the original oil can functions are separated. The first oil can 2 ensures basic oil storage, while the second oil can 1 can be used for gas-liquid separation of oil-gas mixture, ensuring that the oil-gas mixture extracted by the engine 30 is separated more thoroughly and improving the working efficiency of the engine 30.

[0067] The second oil reservoir 1 is adapted to be connected to the engine 30 of the vehicle 100. The second oil reservoir 1 is used to receive the oil-gas mixture from the engine 30 and perform gas-liquid separation. The first oil reservoir 2 is connected to the second oil reservoir 1. The first oil reservoir 2 is used to store the engine oil after gas-liquid separation by the second oil reservoir 1. The first oil reservoir 2 is adapted to be connected to the engine 30 and adapted to supply engine oil to the engine 30. Wherein, along the length direction of the vehicle 100, the first oil reservoir 2 is adapted to be closer to the front end of the vehicle 100 than the second oil reservoir 1.

[0068] Specifically, the first oil reservoir 2 can be used to store oil, and the second oil reservoir 1 is located between the first oil reservoir 2 and the engine 30. When the engine 30 needs it, the oil in the first oil reservoir 2 can be separated into gas and liquid through the second oil reservoir 1 before entering the engine 30.

[0069] In some embodiments, the second oil reservoir 1 includes a gas-liquid separation structure 11 and an oil storage structure 12. The oil inlet end 111 and the exhaust end 112 of the gas-liquid separation structure 11 are adapted to be connected to the engine 30. The oil storage structure 12 is connected to the oil outlet end 115 of the gas-liquid separation structure 11. The first oil reservoir 2 is connected to the oil storage structure 12.

[0070] Thus, the second oil reservoir 1 can both store oil through the oil storage structure 12 and separate the oil from the gas through the gas-liquid separator 11 before supplying it to the engine 30. This allows the oil in the oil storage structure 12 of the second oil reservoir 1 to be used in the engine 30 as soon as needed, ensuring the rapid response of the vehicle 100, while also improving the working efficiency of the engine 30 through gas-liquid separation.

[0071] Specifically, the first oil reservoir 2 can be connected to the oil storage structure 12 of the second oil reservoir 1. At this time, the first oil reservoir 2 can supply oil to the oil storage structure 12. The oil in the oil storage structure 12 enters the engine 30 after passing through the gas-liquid separation structure 11.

[0072] In some embodiments, the gas-liquid separation structure 11 includes a first shell portion 113 and an oil-blocking portion 114 disposed below the first shell portion 113. A gas-liquid separation chamber 1131 is formed between the first shell portion 113 and the oil-blocking portion 114. The oil inlet end 111 and the exhaust end 112 are both connected to the gas-liquid separation chamber 1131.

[0073] The oil outlet 115 is located between the oil blocking part 114 or the oil blocking part 114 and the first shell part 113, and the oil storage structure 12 is located below the oil blocking part 114 and is connected to the oil outlet 115.

[0074] In this way, the oil can enter the gas-liquid separation structure 11 from the oil inlet 111. The gas-liquid separation structure 11 can separate the oil and gas. The separated gas can enter the crankcase of the engine 30 through the exhaust end 112. The separated oil can reach the oil baffle 114 through the oil outlet 115. The oil baffle 114 can buffer and slow down the oil, so that the oil can return to the oil storage structure 12 by its own gravity.

[0075] In some embodiments, the oil baffle 114 includes a first oil baffle 1141 and a second oil baffle 1142 located below the first oil baffle 1141;

[0076] The gas-liquid separation chamber 1131 is located between the first shell portion 113 and the first oil-blocking portion 1141. The first oil-blocking portion 1141 is connected to the second oil-blocking portion 1142. The oil outlet 115 is located between the second oil-blocking portion 1142 or between the second oil-blocking portion 1142 and the first shell portion 113. The oil storage structure 12 is located below the second oil-blocking portion 1142.

[0077] In this way, the gas-liquid separation structure 11 can separate oil and gas. The separated oil can enter the first oil-blocking section 1141 and the second oil-blocking section 1142 sequentially after passing through the oil outlet 115. The first oil-blocking section 1141 and the second oil-blocking section 1142 can simultaneously buffer the oil, reducing the speed at which the oil falls back. This prevents the oil from splashing and generating bubbles when it returns to the oil storage structure 12 too quickly.

[0078] In some embodiments, the first oil-blocking part 1141 includes a curved separation plate, and the second oil-blocking part 1142 includes a flat mesh plate. The flat mesh plate is perpendicular to the height direction of the second oil reservoir 1, and the inclined surface of the curved separation plate is set at an angle to the height direction of the second oil reservoir 1.

[0079] Specifically, after the gas-liquid separation structure 11 separates the oil and gas, the engine oil can fall back to the curved separation plate under its own gravity. The inclined surface of the curved separation plate can prevent the engine oil from splashing due to vertical fall, thus providing a certain buffering effect. Then the engine oil can slide down the inclined surface to the flat mesh plate. The flat mesh plate can provide secondary buffering for the engine oil and allow the engine oil to return to the oil storage structure 12 through the flat mesh plate, avoiding oil splashing and the generation of air bubbles.

[0080] Preferably, the inclined surface of the curved separation plate can be a conical surface facing the gas-liquid separation structure 11, so that the oil droplets fall on the conical surface to form a buffer, resulting in a better buffering effect.

[0081] In some embodiments, a connecting pipe 24 is provided between the second oil reservoir 1 and the first oil reservoir 2, allowing oil in the oil storage structure 12 to enter the first oil reservoir 2 through the connecting pipe 24. If the first oil reservoir 2 is damaged, the oil in the oil storage structure 12 can be quickly discharged through the connecting pipe 24.

[0082] In some embodiments, the first oil container 2 further includes a pressure balancing end 21, which is connected to the gas-liquid separation chamber 1131.

[0083] Thus, during the oil-gas separation process, the pressure balance end 21 of the first oil reservoir 2 connects to the gas-liquid separation chamber 1131, stabilizing the internal pressure and preventing pressure differences that could prevent oil or oil-gas from exiting the gas-liquid separation chamber 1131. Simultaneously, it balances the pressure between the second oil reservoir 1 and the first oil reservoir 2, ensuring stable circulation of oil and gas between the oil reservoir assembly 10 and the engine 30.

[0084] In some embodiments, the first oil reservoir 2 includes an oil return end 22, which is adapted to be connected to the engine 30.

[0085] In this way, the first oil reservoir 2 can directly deliver oil to the engine 30 through the return oil end 22, and the oil can be used for lubrication inside the engine 30, thereby working with the second oil reservoir 1 to achieve the oil circulation process.

[0086] In some embodiments, the first oil container 2 further includes a drain port 23, which is detachably connected to a sealing element 231.

[0087] In this way, the oil in the oil reservoir assembly 10 can be discharged through the drain port 23 in conjunction with the sealing component 231, so as to facilitate after-sales maintenance.

[0088] Specifically, the drain port 23 can be positioned at a lower location than the first oil reservoir 2, and the first oil reservoir 2 can be positioned even lower than the second oil reservoir 1. This allows the oil in the oil reservoir assembly 10 to be completely drained through the drain port 23 when the sealing member 231 is removed, ensuring complete oil replacement. Furthermore, in this embodiment, the specific form of the sealing member 231 is not limited to meet different needs. For example, the sealing member 231 can be an oil plug.

[0089] In some embodiments, along the length of the vehicle 100, the first oil reservoir 2 is closer to the front end of the vehicle 100 than the second oil reservoir 1.

[0090] In this implementation, if the front of the vehicle 100 is impacted, the first oil reservoir 2, being further forward than the second oil reservoir 1, will rupture and break first. This causes the oil in the first oil reservoir 2 to be rapidly exposed to the environment. Simultaneously, the oil in the oil storage structure 12 of the second oil reservoir 1 can also be exposed to the environment through the damaged area of ​​the first oil reservoir 2. This effectively prevents the second oil reservoir 1, which is closer to the engine 30, from rupturing and splashing oil onto the surface of the exhaust pipe 31 on top of the engine 30, thus avoiding a fire in the engine 30.

[0091] In some embodiments, the end of the first oil reservoir 2 facing the front end of the vehicle 100 is a first front end (not shown in the figure), and the end of the second oil reservoir 1 facing the front end of the vehicle 100 is a second front end (not shown in the figure).

[0092] Along the length of the vehicle 100, the distance between the first front end and the second front end is greater than 430mm.

[0093] For example, the distance between the first front end and the second front end can be 435mm, 440mm, 445mm, 450mm, 455mm, or 460mm. In one example, the distance between the first front end and the second front end can be 440mm. That is, when the front of the vehicle 100 is involved in a collision, the front bumper beam 103 of the vehicle 100 compresses the fan 104 backward. The fan 104 will first compress the first front end of the first oil reservoir 2. At this time, the distance between the fan 104 and the second front end of the second oil reservoir 1 is 430mm. Thus, before the fan 104 impacts and compresses the second front end, the first front end will be completely damaged, causing the first oil reservoir 2 to rupture completely and allowing all the oil in the first oil reservoir 2 to flow out. At the same time, the oil in the oil storage structure 12 of the second oil reservoir 1 can also flow into the first oil reservoir 2 through the pipeline and be released into the environment through the broken part of the first oil reservoir 2. This can prevent the second oil reservoir 1 near the engine 30 from rupturing and causing oil to splash onto the surface of the exhaust pipe 31 on the top of the engine 30, which could lead to the engine 30 catching fire.

[0094] In some embodiments, the structural strength of the first oil can 2 is less than that of the second oil can 1.

[0095] Thus, after the vehicle 100 is involved in a collision, the first oil reservoir 2, with its lower structural strength, can be damaged first, draining all the oil from the oil reservoir assembly 10. The second oil reservoir 1, with its higher structural strength, is less likely to be damaged. The second oil reservoir 1, located closer to the engine 30, is protected as much as possible, thereby protecting the engine 30.

[0096] In some embodiments, the second oil container 1 is made of metal, and the first oil container 2 is made of plastic.

[0097] Thus, the second oil can 1 is made of metal, which ensures its structural strength, while the first oil can 2 is made of plastic, which allows it to not only fulfill its load-bearing function but also to quickly break and drain oil after an impact.

[0098] In this embodiment, the specific materials of the second oil can 1 and the first oil can 2 are not limited to meet different needs. For example, the second oil can 1 can be made of aluminum alloy, and the first oil can 2 can be made of polypropylene, etc. Of course, in other embodiments, the second oil can 1 and the first oil can 2 can also be made of other materials, as long as the structural strength of the first oil can 2 is less than the structural strength of the second oil can 1.

[0099] In some embodiments, along the length of the vehicle 100, the second oil reservoir 1 is located between the engine 30 and the front end of the vehicle 100.

[0100] Thus, the second oil reservoir 1 is located between the engine 30 and the front end of the vehicle 100. When the vehicle 100 is hit from the front, the second oil reservoir 1 can block the front of the engine 30 and protect the engine 30.

[0101] Specifically, the material of the second oil can 1 can be metal, that is, the second oil can 1 has higher strength, so that the second oil can 1 can act as a support to protect the engine 30 and prevent the engine 30 from being affected by external impacts and vibrations.

[0102] In some embodiments, along the height direction of the vehicle 100, the position of the first oil reservoir 2 is lower than the position of the second oil reservoir 1.

[0103] Thus, the position of the first oil reservoir 2 is lower than that of the second oil reservoir 1, so that the oil is mainly stored in the position of the first oil reservoir 2. This allows the oil in the second oil reservoir 1 to be drained through the drain port 23 of the first oil reservoir 2 during routine maintenance, and also allows the oil in the second oil reservoir 1 and the first oil reservoir 2 to be quickly drained through the damaged part of the first oil reservoir 2 after the vehicle 100 is hit, thereby improving the safety performance of the vehicle 100.

[0104] In some embodiments, along the height direction of the vehicle 100, the first oil reservoir 2 is located on the side of the second oil reservoir 1 away from the engine 30.

[0105] Specifically, the first oil reservoir 2 is the main oil storage element, storing a large amount of oil. The lower position of the first oil reservoir 2 allows the oil to be quickly drained by its own weight. At the same time, the second oil reservoir 1 is lower than the position of the engine 30, and the first oil reservoir 2 is lower than the position of the second oil reservoir 1. In other words, the first oil reservoir 2, which mainly stores engine oil, is located much lower than the position of the engine 30 body. In the event of an impact and breakage of the first oil reservoir 2, engine oil is less likely to splash onto the top of the engine 30, causing the engine 30 to catch fire.

[0106] In some embodiments, along the height direction of the vehicle 100, the distance between the highest point of the first oil reservoir 2 and the highest point of the second oil reservoir 1 is greater than or equal to 65 mm and less than or equal to 85 mm. For example, the distance between the top of the first oil reservoir 2 and the top of the second oil reservoir 1 can be 65 mm, 70 mm, 75 mm, 80 mm, or 85 mm.

[0107] In some embodiments, the engine 30 includes an exhaust pipe 31, and the distance from the first oil reservoir 2 to the exhaust pipe 31 along the height direction of the vehicle 100 is greater than 450 mm. For example, the distance from the first oil reservoir 2 to the exhaust pipe 31 along the height direction of the vehicle 100 can be 455 mm, 460 mm, 465 mm, 470 mm, etc.

[0108] Thus, the first oil reservoir 2 is relatively far from the second oil reservoir 1 and the exhaust pipe 31 of the engine 30 in the vertical direction. In other words, the first oil reservoir 2 is positioned lower than the second oil reservoir 1 and significantly lower than the engine 30 itself. Therefore, if the first oil reservoir 2 ruptures upon impact, engine oil is less likely to splash onto the top of the engine 30, potentially causing it to catch fire. Consequently, in the event of a collision, core components such as the engine 30 are less likely to be damaged, thus improving the safety of the vehicle 100.

[0109] In some embodiments, the distance between the second oil reservoir 1 and the first oil reservoir 2 in the width direction of the vehicle 100 is greater than 0.

[0110] Thus, the second oil reservoir 1 and the first oil reservoir 2 are misaligned in the width direction, preventing direct contact between them in the event of a frontal impact, thereby improving the safety performance of the vehicle 100. Simultaneously, the engine 30 is located behind the second oil reservoir 1, and the first oil reservoir 2 is also misaligned with the main structure of the engine 30, preventing oil from splashing onto the engine 30 should the first oil reservoir 2 break.

[0111] In other embodiments, the distance between the second oil reservoir 1 and the first oil reservoir 2 along the length of the vehicle 100 is greater than 0. This ensures that the second oil reservoir 1 and the first oil reservoir 2 will not directly collide when the vehicle 100 encounters a lateral impact, further improving the safety performance of the vehicle 100.

[0112] In some embodiments, the distance between the second oil reservoir 1 and the first oil reservoir 2 along the width direction of the vehicle 100 is greater than or equal to 250 mm. For example, the distance between the second oil reservoir 1 and the first oil reservoir 2 can be 250 mm, 255 mm, 260 mm, 265 mm, or 270 mm.

[0113] In some embodiments, the distance from the first oil reservoir 2 to the center of the engine 30 along the width direction of the vehicle 100 is not less than 600 mm. For example, the distance from the first oil reservoir 2 to the center of the engine 30 along the width direction of the vehicle 100 can be 600 mm, 605 mm, 610 mm, 615 mm, or 620 mm.

[0114] Specifically, the second oil reservoir 1 and the engine 30 are arranged along the width of the vehicle 100 in this way, which can effectively maintain a safe distance and prevent the oil in the first oil reservoir 2 from splashing onto the engine 30 and affecting the safety of the engine 30.

[0115] This application provides a power system 200, which includes an engine 30 and an oil reservoir assembly 10 according to any of the above embodiments, wherein the second oil reservoir 1 of the oil reservoir assembly 10 is connected to the engine 30.

[0116] This application provides a vehicle 100, which includes an oil reservoir assembly 10 according to any of the above embodiments, or a power system 200 according to the above embodiments.

[0117] In the oil reservoir assembly 10, power system 200, and vehicle 100 of this application embodiment, the oil reservoir assembly 10 is applied to the vehicle 100. The oil reservoir assembly 10 includes a second oil reservoir 1 and a first oil reservoir 2. The second oil reservoir 1 is adapted to be connected to the engine 30 of the vehicle 100, and the first oil reservoir 2 is connected to the second oil reservoir 1. The second oil reservoir 1 is used for gas-liquid separation of the engine oil in the engine 30, and the first oil reservoir 2 is used for storing the engine oil. Thus, the oil reservoir assembly 10 is divided into a second oil reservoir 1 and a first oil reservoir 2, each with its own function. The original oil reservoir functions are split. The first oil reservoir 2 ensures basic oil storage, while the second oil reservoir 1 can be used for gas-liquid separation of the engine oil, ensuring more thorough separation of the oil-gas mixture extracted from the engine 30 and improving the working efficiency of the engine 30.

[0118] In some embodiments, a front bumper beam 103 is also included, which forms the front end of the vehicle 100, with the engine 30 located at the rear of the front bumper beam 103, and a second oil reservoir 1 disposed between the front bumper beam 103 and the engine 30.

[0119] Thus, the front bumper beam 103 can protect the front end of the vehicle 100. In the event of a minor collision, the front bumper beam 103 can prevent the engine 30 and oil reservoir assembly 10 on the rear side from being affected by impact and vibration.

[0120] In some embodiments, the vehicle 100 may also include a first longitudinal beam 101 and a second longitudinal beam 102 spaced apart along the width direction of the vehicle 100, with the engine 30 located between the first longitudinal beam 101 and the second longitudinal beam 102, and the first oil reservoir 2 located on the side of the first longitudinal beam 101 opposite to the second longitudinal beam 102, or on the side of the second longitudinal beam 102 opposite to the first longitudinal beam 101.

[0121] Thus, the first longitudinal beam 101 and the second longitudinal beam 102 can serve as the support structure of the vehicle 100, providing basic support for the engine 30 and the oil reservoir assembly 10. Furthermore, the engine 30 can be positioned between the first longitudinal beam 101 and the second longitudinal beam 102, allowing the first longitudinal beam 101 and the second longitudinal beam 102 to protect the engine 30 laterally, preventing it from being affected by external impacts and vibrations.

[0122] Specifically, the first oil reservoir 2 is located on the side of the first longitudinal beam 101 opposite to the second longitudinal beam 102, or on the side of the second longitudinal beam 102 opposite to the first longitudinal beam 101. In other words, the first oil reservoir 2 can be located on the outer side of the first longitudinal beam 101 or on the outer side of the second longitudinal beam 102. In one example, the first oil reservoir 2 is located on the side of the first longitudinal beam 101 opposite to the second longitudinal beam 102. This means that the first oil reservoir 2 and the engine 30 are respectively located on opposite sides of the first longitudinal beam 101, allowing the first longitudinal beam 101 to support both the first oil reservoir 2 and the engine 30 while preventing oil from the first oil reservoir 2 from splashing onto the engine 30 due to impact.

[0123] For example, the present invention provides a split oil reservoir assembly 10, which can effectively facilitate the layout of the vehicle space and achieve higher space utilization. The second oil reservoir 1 is designed with a metal structure to enhance its anti-collision function, while the first oil reservoir 2 is designed with a plastic structure to effectively allow the engine oil to flow out from the bottom during a collision, preventing engine oil from splashing onto the top of the vehicle 100 and causing abnormal fires. The main function of the second oil reservoir 1 is to effectively separate the oil-gas mixture drawn back from the engine 30. A small amount of engine oil is stored at the bottom of the reservoir, and the gas is discharged into the crankcase of the engine 30 through the exhaust end 112 at the top. The main function of the first oil reservoir 2 is to store the engine oil of the engine 30.

[0124] Specifically, the second oil reservoir 1 is located behind the fan 104 and mounted on the engine 30 body. The first oil reservoir 2 is located further forward than the second oil reservoir 1, on the side of the first longitudinal beam 101 of the vehicle 100, away from the engine 30 body and the second oil reservoir 1. The first oil reservoir 2 and the second oil reservoir 1 are connected by a pipeline to ensure the flow of oil and gas. When the vehicle is involved in a collision, the front bumper beam 103 compresses the fan 104 backward, and the fan 104 will first compress the first oil reservoir 2, causing the first oil reservoir 2 to rupture. The oil inside the second oil reservoir 1 will also flow into the first oil reservoir 2 through the pipeline, causing the oil to flow out from the first oil reservoir 2. This prevents the second oil reservoir 1, which is close to the engine 30, from rupturing and splashing oil onto the surface of the exhaust pipe 31 on top of the engine 30, thus preventing the engine 30 from catching fire. The first oil reservoir 2, which mainly stores engine oil, is located at the lower end of the first longitudinal beam 101. Its position in the vehicle is lower than that of the second oil reservoir 1 and much lower than that of the engine 30 body. When the first oil reservoir 2 is impacted and ruptured, the engine oil is less likely to splash onto the top of the engine 30 and cause the engine 30 to catch fire.

[0125] In this embodiment, the distance between the side of the first oil reservoir 2 and the side of the second oil reservoir 1 is greater than 250mm, the distance between the first oil reservoir 2 and the center of the engine 30 is greater than 600mm, and the distance between the first oil reservoir 2 and the front side of the second oil reservoir 1, viewed from the length direction of the vehicle 100, is greater than 430mm. The distance between the top of the first oil reservoir 2 and the top of the second oil reservoir 1 is between 65-85mm, and the distance between the first oil reservoir 2 and the exhaust pipe 31 of the engine 30 is greater than 450mm.

[0126] Furthermore, the oil-gas mixture extracted from the engine 30 flows into the second oil reservoir 1 through the oil return pipe. The second oil reservoir 1 is designed with a gas-liquid separation structure 11. The separated gas returns to the crankcase of the engine 30 through the exhaust end 112, while the oil returns to the second oil reservoir 1 through the oil inlet end 111. To ensure smooth oil flow, a pressure balance end 21 is designed between the first oil reservoir 2 and the second oil reservoir 1, connecting the two reservoirs to balance the pressure. The oil in the first oil reservoir 2 returns to the engine 30 through the oil return end 22 for lubrication. For convenient after-sales maintenance, a sealing element 231 is designed at the bottom of the first oil reservoir 2.

[0127] Furthermore, the engine 30 introduces the oil-gas mixture through the oil inlet 111 into the gas-liquid separator 11, where the gas-liquid separator 11 separates the oil and gas. The separated gas is then discharged into the crankcase of the engine 30 through the exhaust end 112. The separated oil passes through the first oil baffle 1141 and the second oil baffle 1142, where the oil and gas are further separated, and the oil flow rate is reduced to prevent air bubbles from forming when the oil falls back down. The bottom of the oil reservoir has an outlet for the second oil reservoir 1 connected to the first oil reservoir 2, and the top has a pressure balancing end 21 between the first oil reservoir 2 and the second oil reservoir 1 to balance the pressure between them. To better monitor the oil level, an oil level sensor 13 can also be designed in the second oil reservoir 1.

[0128] In summary, the oil reservoir assembly 10 of this embodiment adopts a split structure. The main function of the second oil reservoir 1 is to separate the oil-gas mixture extracted from the engine 30 and store a small amount of engine oil. The main function of the first oil reservoir 2 is to store engine oil. The second oil reservoir 1 can be designed as a metal structure to increase strength and prevent breakage upon impact. The first oil reservoir 2 can be designed as a plastic structure, which is more prone to breakage upon impact. The second oil reservoir 1 is located at the rear end of the engine 30 body, so that the first oil reservoir 2 breaks first upon impact, and the engine oil flows out from the first oil reservoir 2. The first oil reservoir 2 is designed to be lower in height than the second oil reservoir 1 and farther away from the engine 30 body. When the first oil reservoir 2 breaks, the engine oil will not splash onto the top of the engine 30, causing the engine 30 to catch fire. The second oil reservoir 1 is designed with a double baffle structure, which can more effectively separate the oil-gas mixture and reduce the oil descent speed, avoiding the generation of air bubbles when the oil falls back.
