Description

Technical Field

[0001] This invention relates to the field of engine technology, and in particular to an oil reservoir assembly, an engine, a powertrain, and a vehicle. Background Technology

[0002] An engine oil reservoir is a device in a vehicle's lubrication system used to store and replenish engine oil. In related technologies, dry sump lubrication systems use an external oil reservoir, replacing the function of a traditional wet sump. This external reservoir is independent of the engine and stores sufficient oil to ensure a stable oil supply. Dry sump lubrication systems separate the oil storage from the lubrication process, avoiding the resistance caused by crankshaft agitation of the oil, while maintaining crankcase vacuum to reduce piston movement resistance and improve engine efficiency. However, external oil reservoirs are susceptible to compression in the event of a collision, potentially leading to deformation and breakage, posing a safety hazard. Therefore, there is room for improvement. Summary of the Invention

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following is for reference. Figures 1-5 The specific embodiments of the present invention will be described in detail.

[0043] According to a first aspect of the present invention, an oil reservoir assembly 30 is provided for an engine 10, the oil reservoir assembly 30 comprising a first portion and a second portion; the first portion is adapted to be disposed near an exhaust pipe 101 of the engine 10, and the second portion is adapted to be disposed away from the exhaust pipe 101 of the engine 10. The first portion has a greater strength than the second portion.

[0044] The oil reservoir assembly 30 includes a first part 3101 and a second part 3102. The first part 3101 is adapted to be disposed near the exhaust pipe 101 of the engine 10, and the second part 3102 is adapted to be disposed away from the exhaust pipe 101 of the engine 10. The strength of the first part 3101 is greater than the strength of the second part 3102, so that when the oil reservoir assembly 30 is impacted, the second part 3102, which is away from the exhaust pipe 101, breaks before the first part 3101, which is near the exhaust pipe 101 of the engine 10. The oil stored in the oil reservoir assembly 30 leaks out from the position away from the exhaust pipe 101 of the engine 10, reducing the safety hazard caused by oil spraying onto the surface of the exhaust pipe 101 and causing fire and smoke.

[0045] According to the first aspect of the present invention, an oil reservoir assembly 30 is provided for oil storage and safety protection of an engine 10. The oil reservoir assembly 30 adopts a split-type structural design, specifically comprising a first part and a second part connected to each other. The first part is configured to be installed adjacent to the exhaust pipe 101 of the engine 10 to adapt to the high-temperature environment of that area; the second part is arranged away from the exhaust pipe 101, typically near a relatively safe area within the engine compartment. Through this spatial arrangement, the oil reservoir assembly 30, while fulfilling its basic oil storage function, actively avoids high-temperature components of the engine.

[0046] In some specific implementations, the installation distance between the first part 3101 and the exhaust pipe 101 can be controlled within the range of 50-150mm, ensuring both the necessary thermal radiation safety distance and avoiding excessive occupation of engine compartment space. The fracture threshold of the second part 3102 is calibrated experimentally; for example, its compressive strength is set to 60%-80% of that of the first part, ensuring that when the collision energy reaches the critical value, the oil leakage point is always located in the opposite direction to the exhaust pipe 101. When the vehicle experiences a frontal or side collision, the fracture response time of the second part 3102 is earlier than that of the first part 3101, and this time difference provides a critical time window for the safe diversion of oil.

[0047] In terms of safety protection, the solution of this application embodiment couples and optimizes the structural strength distribution and spatial location distribution. By strengthening the structural integrity of the high-temperature area while weakening the impact resistance of the low-temperature area, a dual protection mechanism of "near-end protection and far-end pressure relief" is formed. When the impact shock wave is transmitted to the oil reservoir assembly 30, the preferential rupture of the second part 3102 not only reduces the probability of oil spraying onto the surface of the exhaust pipe 101, but also guides the oil to a preset collection tank or diversion channel through directional leakage, so that most of the leaked oil can be safely recovered or guided to a non-hazardous area.

[0048] In practical implementation, regarding structural strength design, the first and second parts employ differentiated structures, materials, or processes to ensure that the strength of the first part is greater than that of the second part. For example, in some exemplary embodiments, the mechanical strength of the first part can be enhanced by increasing wall thickness, selecting high-strength materials, setting additional reinforcing structures, or adding reinforcing ribs, enabling it to withstand higher levels of impact loads. The second part, relative to the first part, forms a relatively weak area. The core of this strength differentiation is that when the oil reservoir assembly 30 is subjected to an external impact, the second part, being farther from the exhaust pipe 101, has lower mechanical strength and will preferentially fracture. At this time, the oil leakage path is forcibly guided away from the exhaust pipe 101, thereby spatially isolating the high-temperature heat source from the flammable liquid.

[0049] In an exemplary embodiment, the oil can assembly 30 includes an oil can 310, which includes a first body portion 3101 and a second body portion 3102. The first body portion 3101 is adapted to be disposed near the exhaust pipe 101 of the engine 10, and the second body portion 3102 is adapted to be disposed away from the exhaust pipe 101 of the engine 10. The strength of the first body portion 3101 is greater than the strength of the second body portion 3102. In a specific implementation, the oil can 310 may also include a third body portion 3103. That is, the oil can 310 may be composed of three parts: upper, middle, and lower, formed by welding.

[0050] In an exemplary embodiment, the oil reservoir assembly 30 includes an oil reservoir 310 with differentiated strength through a partitioned design. Specifically, the oil reservoir 310 is divided into a first reservoir body 3101 and a second reservoir body 3102 that are interconnected. The first reservoir body 3101 is located on the side near the engine exhaust pipe 101, and its structure is reinforced by increasing the local wall thickness, using higher-strength engineering plastics, and adding transverse or longitudinal reinforcing ribs internally or externally. These designs enable this area to effectively resist high-temperature radiation from the engine compartment and potential collision impacts. The corresponding second reservoir body 3102 is located in the opposite direction of the exhaust pipe 101, with a relatively thinner wall thickness, using a material of ordinary strength grade, and without additional reinforcing structures, thus forming a clear mechanical strength gradient.

[0051] Therefore, in some embodiments, the first pot body portion 3101 and the second pot body portion 3102 may be made of different materials.

[0052] In some embodiments, the oil reservoir assembly 30 includes an oil reservoir 310 and protective members 320 / 340. The oil reservoir 310 includes a first reservoir body 3101 and a second reservoir body 3102. The first reservoir body 3101 is disposed near the exhaust pipe 101 of the engine 10, and the second reservoir body 3102 is adapted to be disposed away from the exhaust pipe 101 of the engine 10. The protective member is disposed outside the first reservoir body 3101.

[0053] In some embodiments, the protective element 320 of the oil can assembly 30 is structurally combined with the oil can 310 to form a strength-differentiated configuration. Specifically, as an example, the protective element 320 may adopt a U-shaped or semi-enclosed structure, wrapping around the outer surface of the first can body portion 3101 of the oil can 310, and the two are fixed by bolts or snap-fit ​​connections to form a composite structure. The material of the protective cover 320 may be the same high-strength metal or engineering plastic as the first can body portion 3101 to provide additional rigid support. This combined design allows the first can body portion 3101 and the protective element 320 to jointly constitute the first part 3101, and its overall strength is significantly improved through a superposition effect, while the unwrapped second can body portion 3102, as the second part 3102, maintains its original strength level.

[0054] In other embodiments, the protective member 340 may also be designed as a plate-shaped protective structure, arranged parallel to the outer side of the first pot body 3101 facing the exhaust pipe 101, for example, it may cover the outer surface of the first pot body 3101 facing the exhaust pipe 101. The coverage area of ​​the protective plate 340 may extend to the circumferential area of ​​the first pot body 3101, forming a continuous protective layer in the direction of the radiating heat source of the exhaust pipe 101. In this case, the strength of the first pot body 3101 and the additional strength of the protective plate 340 work together to make the impact resistance of the combined first part 3101 higher than that of the second pot body 3102, ensuring that the collision energy is preferentially released from the unprotected second part 3102 during transmission. Through this design, the overall structural integrity of the oil can assembly 30 is maintained, and the modular design of the detachable protective member achieves convenient maintenance.

[0055] In some embodiments, the protective element is constructed as a protective cover 320, which is used to enclose the first pot body portion 3101. The protective cover 320 may be made of the same high-strength metal or engineering plastic as the first pot body portion 3101 to provide additional rigid support. This combined design allows the first pot body portion 3101 and the protective element 320 to together constitute the first part 3101, and its overall strength is significantly improved through a superposition effect, while the unenclosed second pot body portion 3102, as the second part 3102, maintains its original strength level.

[0056] In some embodiments, the first reservoir body 3101 has a filler neck 3104. The reservoir assembly 30 also includes a filler neck cap 380 and a protective cap 330. The filler neck cap 380 is used to detachably close the filler neck 3104, and the protective cap 330 covers the outside of the filler neck cap 380. In some embodiments, the protective cap 330 is made of metal; the first reservoir body 3101 is provided with a metal bushing 390, and the protective cap 330 is connected to the metal bushing 390 via a connector 370.

[0057] For example, in a specific implementation, the metal shell of the protective cover 330 completely covers the outside of the filler cap 380, and its outline is parallel to the shape of the filler cap 380. It is fastened to the bushing 390 by circumferentially distributed connectors 370. When an external impact acts on the filler area, the metal protective cover 330 preferentially bears the load. Its rigid structure can effectively block the upward trajectory of the filler cap 380, while limiting the oil splash range to the closed space formed by the protective cover 330 and the filler cap 380. The opening direction of the protective cover 330 is oriented so that its guide surface faces away from the high-temperature area where the exhaust pipe 101 is located, ensuring that the leaked oil flows in a preset safe direction.

[0058] In other embodiments, the protective cover 330 can adopt a split modular design, with its lower half fixed to the metal bushing 390 and its upper half opening and closing via a hinge structure. This design maintains protective performance while preserving normal opening and closing space for the filler cap 380. The mating surface between the metal bushing 390 and the first reservoir body 3101 adopts a serrated interlocking structure to enhance the torsional resistance between the two. The dome-shaped shape of the protective cover 330 can guide collision fragments to slide to both sides, avoiding direct impact on the weak parts of the filler cap 380. By combining the reinforced design of the protective cover 330 with that of the first reservoir body 3101, the oil reservoir assembly 30 can, under collision conditions, both block the risk of oil splashing from the high-temperature side through the metal protective layer and achieve controllable deformation through the pre-set weakened area of ​​the second reservoir body 3102, forming a layered energy dissipation mechanism.

[0059] In specific implementation, the metal protective cover 330 adopts a metal shell that matches the shape of the fuel filler cap 380, completely enclosing the fuel filler cap 380 to form an outer protective barrier. This metal shell is rigidly connected through a metal bushing 390 pre-embedded in the first vessel body 3101, forming a composite structure 36 of metal protective layer and plastic sealing layer from the outside in. When a collision causes the fuel filler cap 380 to deform, the metal protective cover 330 absorbs the impact energy through its own deformation, while simultaneously constraining the displacement range of the fuel filler cap 380. The opening direction of the protective cover 330 maintains a certain angle with the exhaust pipe 101; splashed oil, after being blocked by its metal wall, is guided away from the high-temperature area along the inclined direction of the opening, avoiding the heat radiation path of the exhaust pipe 101. The metal bushing 390 and the first vessel body 3101 adopt a sawtooth-shaped interlocking structure, improving the torsional resistance of the connection interface. The circumferentially distributed connectors 370 can be designed with countersunk bolts, maintaining connection strength while preventing secondary damage to protruding parts during collisions. A buffer gap is maintained between the protective cover 330 and the filler cap 380, allowing the metal shell of the protective cover 330 to deform preferentially to absorb energy.

[0060] This application also discloses an engine 10, which includes a body 103, an exhaust pipe 101, and the aforementioned oil reservoir assembly 30.

[0061] The exhaust pipe 101 is located above the engine body 103; the oil reservoir assembly 30 includes an oil reservoir 310, which includes a first reservoir portion 3101 located at the top and a second reservoir portion 3102 located at the bottom. The first reservoir portion 3101 is disposed close to the exhaust pipe 101 of the engine 10, and the second reservoir portion 3102 is disposed away from the exhaust pipe 101 of the engine 10 and forms a chamber for containing lubricating oil. The first reservoir portion 3101 and the second reservoir portion 3102 are made of different materials and satisfy the condition that the strength of the first reservoir portion 3101 is greater than the strength of the second reservoir portion 3102.

[0062] For example, during manufacturing, the first vessel body 3101 and the second vessel body 3102 can be integrally molded, but the wall thickness and reinforcing structure of the two areas can be controlled differently through mold design. For instance, during injection molding, the wall thickness of the first vessel body 3101 can be increased by 20%-30% by adjusting the mold cavity thickness, while pre-setting the forming space for reinforcing ribs in the corresponding areas. For metal oil cans, a double-layer steel plate stacking structure can be added in high-temperature areas through stamping, while a single-layer structure is maintained in non-high-temperature areas. This process ensures the integrity of the overall structure and precisely achieves the strength distribution of different areas. When a vehicle collides, the impact energy is first transferred to the second vessel body 3102, which has lower mechanical strength, causing it to break at the pre-set weak point, while the high-strength first vessel body 3101 maintains structural stability, thereby forcibly guiding the oil leakage path to a safe area away from the high-temperature exhaust pipe.

[0063] In some embodiments, the exhaust pipe 101 is located above the engine body 103; the oil reservoir assembly 30 includes an oil reservoir 310 and a protective member 320. The oil reservoir 310 includes a first reservoir portion 3101 located at the upper part and a second reservoir portion 3102 located at the lower part. The first reservoir portion 3101 is disposed close to the exhaust pipe 101 of the engine 10, and the second reservoir portion 3102 is disposed away from the exhaust pipe 101 of the engine 10 and forms a chamber for containing lubricating oil. The protective member 320 is disposed outside the first reservoir portion 3101 and separates the first reservoir portion 3101 from the exhaust pipe 101. In some embodiments, the protective member 320 is constructed as a protective cover 320, which is shaped to conform to the first reservoir portion 3101 and covers the upper part of the first reservoir portion 3101.

[0064] Furthermore, the oil reservoir assembly 30 can be connected to the engine block 103 via the oil reservoir mounting bracket 350. In some embodiments, the oil reservoir mounting bracket 350 employs a floating fixing structure, allowing the oil reservoir assembly 30 to generate displacement buffer during a collision. This flexible connection method can effectively absorb some of the impact energy, delay the moment of rupture, and improve the passive safety performance of the engine compartment.

[0065] The above structural configuration and its purpose have been described in detail in the previous embodiments and will not be repeated here. In some application scenarios, the exhaust pipe 101 of the engine 10 is located above the engine body 103. For example, for spatial layout adaptability, such as in a transverse engine compartment, the exhaust pipe is positioned above to avoid chassis components such as the electric drive assembly, gearbox, and drive shaft. This arrangement is particularly suitable for compact vehicles, effectively utilizing the upper space of the engine and avoiding interference with the suspension system. Correspondingly, the oil reservoir 310 includes a first reservoir body 3101 located at the upper part and a second reservoir body 3102 located at the lower part. The first reservoir body 3101 is located close to the exhaust pipe 101 of the engine 10, and the second reservoir body 3102 is located away from the exhaust pipe 101 of the engine 10 and forms a chamber for containing lubricating oil.

[0066] For example, in some embodiments, the powertrain 100 further includes an electric drive assembly (not shown) located below the engine 10, i.e., positioned... Figure 1 The electric drive assembly is located at the bottom of the engine 10. Positioning the electric drive assembly below the engine 10 compresses vertical space; through a layered arrangement, the engine 10 and the electric drive assembly share longitudinal projection space, typically reducing the overall powertrain height by 20%-30%. This layout is particularly suitable for hybrid vehicles, forming a compact series powertrain with a P1+P3 dual-motor structure. Furthermore, the drive shaft of the electric drive assembly and the gearbox input shaft are coaxial, reducing the number of gear meshing stages and increasing transmission efficiency to over 97%. Compared to a traditional parallel shaft layout, this design reduces mechanical energy loss by 2-3%. Additionally, a vertical thermal insulation layer is formed between the high-temperature zone of the engine 10 (exhaust side temperature > 600°C) and the electric drive assembly (operating temperature < 150°C), reducing the temperature rise of the electric drive assembly windings. This arrangement requires the exhaust pipe 101 of the engine 10 to be located above the engine body 103.

[0067] In some embodiments, the side of the second reservoir portion 3102 away from the engine 10 is partially recessed and forms a clearance opening 360. In some embodiments, the oil reservoir assembly 30 further includes a protective plate 340 disposed on the side of the second reservoir portion 3102 away from the engine 10.

[0068] Corresponding to the impact force direction of the oil reservoir assembly 130, the protective cover 320 mainly covers the upper middle part of the oil reservoir 310. In the direction closer to the engine body 103, the oil reservoir 310, through its contoured design, can completely cover the side of the engine body 103 as much as possible. On the side away from the engine body 103, a partial notch is provided, forming a clearance opening 360. When the oil reservoir 310 is subjected to external forces such as impact, the protective plate 340, for example, a metal protective plate 340, can initially withstand part of the force. When the external force further compresses the oil reservoir 310, causing it to deform and break, the covering of the protective cover 320 allows oil to splash from the clearance opening 360 side away from the engine body 103. In the direction closer to the engine body 103, due to the protective effect of the protective cover 320, oil will not splash towards the engine body 103, especially towards the top near the exhaust pipe 101, avoiding collision safety risks.

[0069] This application also discloses a powertrain 100, including the aforementioned engine 10.

[0070] This application also discloses a vehicle that includes the aforementioned engine 10, or includes the aforementioned powertrain 100.

[0071] In some embodiments, the engine 10 is located in the front compartment of the vehicle; in the longitudinal direction of the vehicle, the oil reservoir assembly 30 protrudes forward from the body 103 of the engine 10.

[0072] The oil reservoir assembly 30 includes a first part 3101 and a second part 3102. The first part 3101 is adapted to be disposed near the exhaust pipe 101 of the engine 10, and the second part 3102 is adapted to be disposed away from the exhaust pipe 101 of the engine 10. The strength of the first part 3101 is greater than the strength of the second part 3102, so that when the oil reservoir assembly 30 is impacted, the second part 3102, which is away from the exhaust pipe 101, breaks before the first part 3101, which is near the exhaust pipe 101 of the engine 10. The oil stored in the oil reservoir assembly 30 leaks out from the position away from the exhaust pipe 101 of the engine 10, reducing the safety hazard caused by oil spraying onto the surface of the exhaust pipe 101 and causing fire and smoke.

[0073] It is understood that the aforementioned engine 10, powertrain 100, and vehicle in this application inherit improvements from the aforementioned oil reservoir assembly 130, therefore the improvements will not be explained separately. Furthermore, since the improvements in this application mainly lie in the oil reservoir assembly 130, engine 10, and powertrain 100, no separate view is provided to show the aforementioned vehicle, and it can be understood and implemented according to the conventional form.
