Detailed Implementation

[0043] 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.

[0044] The following description, with reference to the accompanying drawings, describes a fuel supply assembly 1 according to an embodiment of this application, which is used to supply fuel to an engine.

[0045] As shown in Figures 1-3, the oil supply assembly 1 according to an embodiment of this application includes a housing 100.

[0046] The housing 100 is constructed as part of the engine. The housing 100 has a first chamber 21 for containing fuel. The first chamber 21 is adapted to be connected to the engine via an oil passage to supply fuel to the engine. By storing the fuel in the housing 100 of the engine, there is no need to reserve space for fuel storage on the vehicle chassis, which makes it easier to reserve more space for other components on the vehicle chassis.

[0047] The oil circuit can be an independent oil passage or multiple integrated oil passages; no further restrictions are imposed here.

[0048] Specifically, in the relevant technology, the fuel tank is located in the vehicle chassis, and the engine is located in the front compartment of the vehicle. The fuel tank occupies a large space on the vehicle chassis. By storing the fuel in the engine housing, there is no need to reserve space for fuel storage on the vehicle chassis, which makes it easier to reserve more space for the components on the vehicle chassis.

[0049] Furthermore, by placing the fuel within the engine housing 100, the fuel and engine are positioned closer together, resulting in a higher degree of integration between the engine and fuel. This facilitates the entry of fuel into the engine, thereby reducing the length of the fuel lines and the space they occupy on the vehicle, making the overall vehicle layout simpler and more aesthetically pleasing.

[0050] Therefore, by storing fuel in the engine housing 100, the fuel supply assembly 1 according to the embodiments of this application eliminates the need to reserve space for fuel storage on the vehicle chassis, thus freeing up more space for other components on the vehicle chassis.

[0051] The fuel supply assembly 1 according to a specific embodiment of this application is described below with reference to the accompanying drawings.

[0052] In some specific embodiments of this application, as shown in Figures 1-3, the oil supply assembly 1 includes a housing 100.

[0053] In some embodiments of this application, as shown in Figures 1 and 2, the fuel supply assembly 1 further includes a fuel pump 32, which is connected to the combustion chamber of the engine through a first fuel line. The fuel pump 32 is used to pump fuel into the combustion chamber of the engine to provide fuel for the engine, so that the fuel can mix with air in the combustion chamber and be ignited, thereby enabling the engine to output driving force.

[0054] The first oil pipe can be an independent pipe or an integrated set of multiple oil pipes; no further restrictions are imposed here.

[0055] In some optional embodiments of this application, the fuel pump 32 is disposed in the first chamber 21 to pump the fuel in the first chamber 21 to the combustion chamber of the engine to provide fuel for the engine, so that the fuel can mix with air in the combustion chamber and be ignited, thereby enabling the engine to output driving force.

[0056] Furthermore, by placing the fuel pump 32 inside the first chamber 21, the fuel pump 32 and the engine are integrated, which facilitates the entry of fuel into the engine, reduces the length of the first fuel line, reduces the space occupied by the first fuel line on the vehicle, and makes the overall vehicle layout simpler and more aesthetically pleasing.

[0057] In some embodiments, the housing 100 is configured as the oil pan of an engine, and the fuel pump 32 is disposed in the first chamber 21. The fuel pump 32 does not occupy additional space and there is no need to increase the size of the oil pan to accommodate the fuel pump 32.

[0058] In some alternative embodiments of this application, a second chamber 22 is further provided inside the housing 100. The second chamber 22 is located outside the first chamber 21 and is connected to the first chamber 21. A fuel pump 32 is located inside the second chamber 22 to pump the fuel in the first chamber 21 and / or the second chamber 22 to the combustion chamber of the engine to provide fuel for the engine, so that the fuel can mix with air in the combustion chamber and be ignited, thereby enabling the engine to output driving force.

[0059] Furthermore, by placing the fuel pump 32 within the second chamber 22, the fuel pump 32 and the engine are integrated, which facilitates fuel entry into the engine, reduces the length of the first fuel line, reduces the space occupied by the first fuel line on the vehicle, and makes the overall vehicle layout simpler and more aesthetically pleasing.

[0060] In some embodiments, as shown in FIG3, the first sidewall 203 of the first chamber 21 separates the first chamber 21 and the second chamber 22. The lower part of the first sidewall 203 is provided with an oil inlet, which connects the first chamber 21 and the second chamber 22. Fuel in the first chamber 21 can enter the second chamber 22 through the oil inlet. The fuel pump 32 can pump fuel from the first chamber 21 and / or the second chamber 22 to the combustion chamber of the engine.

[0061] By connecting the first chamber 21 and the second chamber 22 through an oil passage, fuel can be stored simultaneously in the first chamber 21 and the second chamber 22, thereby increasing the fuel storage capacity of the casing 100.

[0062] In some examples, there is a gap between the bottom of the fuel pump 32 and the bottom wall of the second chamber 22 to prevent the fuel pump 32 from blocking the fuel passage and affecting the fuel flow efficiency of the first chamber 21 and the second chamber 22.

[0063] In some specific embodiments of this application, as shown in FIG2, the housing 100 is provided with a first through hole 24, and the refueling pipe 41 communicates with the first chamber 21 or the second chamber 22 through the first through hole 24 for supplying fuel to the first chamber 21 or the second chamber 22.

[0064] In some embodiments, one end of the refueling pipe 41 is connected to the first through hole 24, and the other end is connected to the vehicle's refueling port. External fuel enters the first chamber 21 or the second chamber 22 through the refueling pipe 41 and the first through hole 24 to replenish the fuel in the first chamber 21 or the second chamber 22.

[0065] In some embodiments, as shown in FIG2, the fuel supply assembly 1 further includes a fuel filler pipe connector 43 and a clamp 42. The fuel filler pipe connector 43 is fixed to the first through hole 24. The fuel filler pipe 41 is sleeved on the fuel filler pipe connector 43 and communicates with the first through hole 24. The clamp 42 extends circumferentially along the fuel filler pipe 41 to apply a tightening force to the fuel filler pipe 41, thereby fixing one end of the fuel filler pipe 41 to the fuel filler pipe connector 43, so that external fuel enters the first chamber 21 or the second chamber 22 through the fuel filler pipe 41 and the first through hole 24 to replenish the fuel for the first chamber 21 or the second chamber 22.

[0066] In some examples, the refueling pipe connector 43 is threaded and connected to the first through hole 24.

[0067] In other embodiments, the fuel filler pipe connector 43 is fixed to the housing 100 by a first fastener, so that the fuel filler pipe connector 43 is connected to the first through hole 24.

[0068] The first fastener can be a screw, pin, or other similar component.

[0069] In some embodiments of this application, a baffle plate is provided in the first chamber 21 to suppress fuel sloshing, thereby reducing fuel sloshing during vehicle operation and thus reducing the impact of fuel on the housing 100.

[0070] In some embodiments of this application, an oil float is provided in the first chamber 21. The oil float is used to detect the amount of fuel in the first chamber 21 so as to remind the user to replenish the fuel in time when the fuel in the first chamber 21 is insufficient.

[0071] In some embodiments of this application, as shown in Figures 2 and 3, a third chamber 11 is provided inside the housing 100. The third chamber 11 has a first opening 111. The third chamber 11 is used to contain engine oil to provide lubrication for the engine. Under the action of gravity, the lubricating oil in the engine will flow from the first opening 111 into the third chamber 11 to store the engine oil, so as to realize the circulation of engine oil in the third chamber 11 and the engine, so as to use the engine oil to lubricate the engine.

[0072] In some optional embodiments of this application, an oil pump 31 is provided in the third chamber 11. The oil pump 31 is connected to the engine's lubrication passage through a second oil pipe to pump the oil in the third chamber 11 to the engine's lubrication passage, so that the oil in the third chamber 11 can flow along the lubrication passage to the area of ​​the engine that needs lubrication, thereby achieving engine lubrication.

[0073] The oil pump 31 is located in the third chamber 11, which facilitates the integration of the oil pump 31 and the engine, reduces the length of the second oil pipe, reduces the space occupied by the second oil pipe on the vehicle, and makes the overall vehicle layout simpler and more aesthetically pleasing.

[0074] The lubricating oil passage can be an independent oil passage or multiple integrated oil passages. The second oil pipe can be an independent oil pipe or multiple integrated oil pipes. No further restrictions are imposed here.

[0075] In some embodiments, the third chamber 11 is located below the engine. Driven by the oil pump 31, the oil in the third chamber 11 can overcome gravity and flow upward along the lubrication channel to the area of ​​the engine that needs lubrication. Under the action of gravity, the oil adhering to the engine surface will flow into the third chamber 11 to realize the circulation of oil and thus achieve sufficient lubrication of the engine.

[0076] In some optional embodiments of this application, the third chamber 11 and the first chamber 21 are arranged adjacent to each other so that the first chamber 21 and the third chamber 11 make full use of the space inside the engine, thereby reducing the space occupied by the first chamber 21 and the third chamber 11.

[0077] In some embodiments, the first chamber 21 has a second opening 211, and a first cover 202 is provided over the second opening 211. When oil flows onto the first cover 202, the oil can flow along the first cover 202 into the third chamber 11.

[0078] In some embodiments, the housing 100 is an integrally molded part, which can be formed by molding plastic. The housing 100 has a first chamber 21 and a third chamber 11. The housing 100 has a partition to divide the space inside the housing 100 into the third chamber 11 and the first chamber 21.

[0079] The irregular third chamber 11 and first chamber 21 are formed by plastic molding to accommodate the placement space of the housing 100, thereby making full use of the placement space and increasing the volume of the third chamber 11 and first chamber 21 to store more engine oil and fuel.

[0080] In some other embodiments, as shown in FIG1, the housing 100 includes an oil tank 10 and a fuel tank 20. The fuel tank 20 defines a first chamber 21, and the oil tank 10 defines a third chamber 11. The oil tank 10 and the fuel tank 20 are separately formed and then fixed together, which makes it easier to reduce the molding difficulty and improve the flexibility of the arrangement of the oil tank 10 and the fuel tank 20.

[0081] In some optional embodiments of this application, the third chamber 11 is provided with a second through hole 12, which cooperates with an oil drain plug 44. The oil drain plug 44 is used to open or close the second through hole 12.

[0082] When the engine needs to be repaired or maintained, the oil in the third chamber 11 needs to be drained to facilitate engine operation. The drain plug 44 can be removed from the housing 100. At this time, the drain plug 44 opens the second through hole 12, and the oil in the third chamber 11 is drained from the second through hole 12.

[0083] In some embodiments, the drain plug 44 is a magnetic component. When the engine oil lubricates the engine, metal shavings formed on the engine due to wear will accumulate in the third chamber 11 along with the oil. The drain plug 44 can adsorb the metal shavings so that they can be discharged from the third chamber 11 when the engine is being maintained.

[0084] In some embodiments, the second through hole 12 is located below the side wall of the third chamber 11 so that when the drain plug 44 opens the second through hole 12, as much oil as possible in the third chamber 11 can be discharged from the second through hole 12, thereby reducing the amount of oil remaining in the third chamber 11.

[0085] In some optional embodiments of this application, the walls of the third chamber 11 are coated with heat-insulating material. Since the engine generates heat after running for a period of time, the temperature of the engine oil will also rise. By coating the walls of the third chamber 11 with heat-insulating material, the heat inside the third chamber 11 is isolated from the outside, so as to avoid excessively high temperatures affecting the operation of other components in the vehicle.

[0086] In some embodiments of this application, the housing 100 is configured as an oil pan of an engine.

[0087] In some embodiments, the engine includes a housing body defining an inner cavity having a lower opening.

[0088] In some examples, the housing 100 serves as the oil pan of the engine. The housing 100 closes the lower opening, meaning that both the first chamber 21 and the third chamber 11 are located in the inner cavity. The engine oil will flow into the third chamber 11 under the action of gravity, so that the third chamber 11 can be used to store the engine oil.

[0089] In other examples, a portion of the housing 100 serves as the engine's oil pan, and a portion of the housing 100 closes the lower opening. That is, the third chamber 11 is located inside the inner cavity, and the first chamber 21 is located outside the inner cavity. The engine oil flows into the third chamber 11 under the influence of gravity, so that the third chamber 11 can be used to store the engine oil.

[0090] The engine assembly according to embodiments of this application is described below. The engine assembly according to embodiments of this application includes a fuel supply assembly 1 according to the above embodiments of this application.

[0091] According to the engine assembly of the present application embodiment, fuel is stored in the engine housing 100 by utilizing the fuel supply assembly 1 of the above embodiment of the present application. This eliminates the need to reserve space for fuel storage on the vehicle chassis, making it easier to reserve more space for other components on the vehicle chassis.

[0092] In some embodiments of this application, the engine assembly includes a housing body defining an inner cavity with a lower opening, and an oil supply assembly 1 is disposed below the housing body and closes the lower opening.

[0093] In some examples, the housing 100 serves as the oil pan of the engine. The housing 100 closes the lower opening, meaning that both the first chamber 21 and the third chamber 11 are located in the inner cavity. The engine oil will flow into the third chamber 11 under the action of gravity, so that the third chamber 11 can be used to store the engine oil.

[0094] In other examples, a portion of the housing 100 serves as the engine's oil pan, and a portion of the housing 100 closes the lower opening. That is, the third chamber 11 is located inside the inner cavity, and the first chamber 21 is located outside the inner cavity. The engine oil flows into the third chamber 11 under the influence of gravity, so that the third chamber 11 can be used to store the engine oil.

[0095] In some embodiments of this application, the housing 100 includes a body portion 201 and a first cover 202. The body portion 201 defines a first chamber 21 having a second opening 211 and a third chamber 11 having a first opening 111. The third chamber 11 is used to contain engine oil to provide lubrication for the engine. The first cover 202 is placed over the second opening 211 to close the second opening 211 and prevent fuel in the first chamber 21 from evaporating from the second opening 211.

[0096] In some embodiments, lubricating oil in the engine cavity enters the third chamber 11 from the first opening 111 under the influence of gravity. By providing a first cover 202, the second opening 211 is closed to prevent engine oil from entering the first chamber 21. At the same time, when engine oil flows onto the first cover 202, the first cover 202 guides the flow of engine oil, directing the oil to the first opening 111.

[0097] In some examples, the first cover 202 is a cast or stamped structural component, so that the first cover 202 can close the second opening 211, thereby forming a sealed space in the first chamber 21.

[0098] In some optional embodiments of this application, as shown in FIG2, the engine assembly further includes a first seal 61, which is located between the edges of the first cover 202 and the second opening 211 to seal the gap between the edges of the first cover 202 and the second opening 211, thereby completely sealing the second opening 211 and preventing the evaporation of fuel in the first chamber 21, and preventing external objects from contaminating the fuel in the first chamber 21.

[0099] In some embodiments, as shown in FIG2, the second opening 211 is an opening above the first chamber 21. The first cover 202 is placed over the second opening 211. The first sealing member 61 is located between the edge of the second opening 211 and the circumferential edge of the first cover 202. The second fastener passes through the first cover 202, the first sealing member 61 and the edge of the second opening 211 in sequence to fix the first cover 202 and the first sealing member 61 on the body part 201, so that the first cover 202 and the first sealing member 61 can fully seal the second opening 211.

[0100] The second fastener can be a screw, pin, or other similar part.

[0101] In some optional embodiments of this application, the height of the end of the first cover 202 near the third chamber 11 is lower than the end of the first cover 202 away from the third chamber 11, so that the first cover 202 has a guiding effect on the oil flowing onto it, thereby guiding the oil into the third chamber 11.

[0102] Specifically, when engine oil flows onto the first cover 202, the first cover 202 guides the flow of engine oil to the first opening 111.

[0103] In some embodiments of this application, as shown in FIG2, a second chamber 22 is further provided inside the housing 100. The second chamber 22 is connected to the first chamber 21. A fuel pump 32 is provided inside the second chamber 22 for pumping the fuel in the first chamber 21 and / or the second chamber 22 to the combustion chamber of the engine to provide fuel for the engine, so that the fuel can mix with air in the combustion chamber and be ignited, thereby enabling the engine to output driving force.

[0104] It should be explained here that the second chamber 22 can be part of the first chamber 21, that is, the fuel pump 32 is located inside the first chamber 21, or the second chamber 22 can be a separate chamber, that is, the fuel pump 32 is located outside the first chamber 21.

[0105] In some optional embodiments of this application, the second chamber 22 is disposed outside the first chamber 21, and the fuel pump 32 is disposed in the second chamber 22 to pump the fuel in the first chamber 21 and / or the second chamber 22 to the combustion chamber of the engine to provide fuel for the engine, so that the fuel can mix with air in the combustion chamber and be ignited, thereby enabling the engine to output driving force.

[0106] The second chamber 22 is located outside the first chamber 21, and the fuel pump 32 is located inside the second chamber 22, which facilitates the removal of the fuel pump 32 from the second chamber 22 or the installation of the fuel pump 32 into the second chamber 22.

[0107] In some embodiments, the first chamber 21 has a second opening 211, and a first cover 202 is provided over the second opening 211. The second chamber 22 has a third opening 221, and a second cover 23 is provided over the third opening 221. When the fuel pump 32 needs to be repaired, only the second chamber 22 needs to be opened, without opening the first chamber 21. This can prevent debris from falling from the second opening 211 into the first chamber 21, and also facilitates the operation of the fuel pump 32.

[0108] In some optional embodiments of this application, as shown in Figures 2 and 3, the second chamber 22 has a third opening 221, and the fuel pump 32 is adapted to be disposed in the second chamber 22 through the third opening 221. The fuel pump 32 is provided with a second cover 23, which is used to close the third opening 221 to prevent fuel from evaporating from the third opening 221, to prevent objects in the external environment from entering the second chamber 22 through the third opening 221, and to prevent contamination of the fuel in the second chamber 22 and the first chamber 21.

[0109] The second cover 23 is fixed to the fuel pump 32 and extends circumferentially along the fuel pump 32. The second cover 23 is adapted to cooperate with the edge of the third opening 221. Thus, when the fuel pump 32 is installed from the third opening 221 into the second chamber 22 and is in place, the second cover 23 cooperates with the edge of the third opening 221 to close the third opening 221 together with the fuel pump 32.

[0110] In addition, fixing the second cover 23 to the fuel pump 32 allows the fuel pump 32 and the second cover 23 to be installed simultaneously, which reduces the number of installation steps.

[0111] In some embodiments, when the second cover 23 engages with the edge of the third opening 221, the second cover 23 is subjected to the downward gravity of the fuel pump 32, so that the second cover 23 and the edge of the third opening 221 can fit together fully, thereby enhancing the sealing performance of the second cover 23 over the third opening 221.

[0112] In some specific embodiments of this application, the second chamber 22 is located inside the first chamber 21, that is, the fuel pump 32 is located inside the first chamber 21. In this way, the fuel pump 32 will not occupy additional space, which facilitates the miniaturization design of the housing 100.

[0113] In one embodiment where the housing 100 is configured as the oil pan of an engine, the fuel pump 32 is located within the first chamber 21, thus eliminating the need to enlarge the size of the oil pan to accommodate the fuel pump 32.

[0114] In some embodiments, the first cover 202 has a notch defining a third opening 221, the fuel pump 32 is adapted to be installed from the notch into the second chamber 22, and the second cover 23 is placed over the notch to close it.

[0115] When it is necessary to remove the fuel pump 32, only the second cover 23 inside the notch needs to be opened. There is no need to operate the first cover 202 or open the first chamber 21. This reduces the probability of debris falling into the first chamber 21 and makes it easier to remove the fuel pump 32 for maintenance.

[0116] In some examples, a portion of the first cover 202 is recessed toward the bottom wall of the first chamber 21 to define a notch, the sidewalls of which are located within the first chamber 21, i.e., the notch is located within the first chamber 21, and the second chamber 22 is located within the first chamber 21.

[0117] In some embodiments, the first cover 202 has a third through hole defining a third opening 221, the fuel pump 32 is adapted to be installed from the third through hole into the second chamber 22, and the second cover 23 covers the third through hole to close the third through hole.

[0118] When it is necessary to remove the fuel pump 32, it is only necessary to remove the fuel pump 32 from the third through hole. There is no need to operate the first cover 202 or open the first chamber 21. This reduces the probability of debris falling into the first chamber 21 and makes it easier to remove the fuel pump 32 for maintenance.

[0119] In some specific embodiments of this application, as shown in FIG2, the engine assembly further includes a second seal 62, which is disposed between the second cover 23 and the edge of the third opening 221 to seal the gap between the second cover 23 and the edge of the third opening 221, so as to completely seal the third opening 221, thereby facilitating the reduction of fuel evaporation in the second chamber 22 and preventing external objects from contaminating the fuel in the second chamber 22.

[0120] In some examples, as shown in Figure 2, the second seal 62 is located above the edge of the third opening 221, the second cover 23 is located above the second seal 62, and the third fastener passes through the second cover 23, the second seal 62 and the edge of the third opening 221 in sequence to fix the second cover 23 and the second seal 62 to the top of the second chamber 22, so that the second cover 23 and the second seal 62 can fully close the third opening 221.

[0121] The third fastener can be a screw or a pin, etc.

[0122] In some specific embodiments of this application, the housing 100 includes an oil tank 10 and a fuel tank 20. The fuel tank 20 defines a first chamber 21, and the oil tank 10 defines a third chamber 11. By fixing the housing 100 to the housing body, the fuel tank 20 and the oil tank 10 can be fixed at the bottom of the housing body at the same time, without the need to install the fuel tank 20 and the oil tank 10 separately. This reduces the work station and assembly time for assembling the fuel tank 20 in the vehicle assembly process, simplifies the process sequence and the configuration of assembly personnel, and reduces costs for enterprises.

[0123] The vehicle according to embodiments of this application is described below. The vehicle according to embodiments of this application includes the engine assembly described above according to the embodiments of this application.

[0124] According to the vehicle of the present application embodiment, by utilizing the engine assembly of the above embodiment of the present application, fuel is stored in the engine housing 100, so that there is no need to reserve space for fuel storage on the vehicle chassis, which makes it easier to reserve more space for other components on the vehicle chassis.

[0125] In some embodiments of this application, the engine assembly is located in the front compartment of the vehicle, and the housing 100 includes an oil tank 10 and a fuel tank 20, the fuel tank 20 defining a first chamber 21 and the oil tank 10 defining a third chamber 11.

[0126] By placing both the fuel tank 20 and the oil tank 10 in the front compartment of the vehicle, compared to the prior art where the fuel tank is placed in the chassis of the vehicle, this application eliminates the need to install oil lines on the chassis of the vehicle. This reduces the number of fuel system components in the vehicle, which helps to reduce the overall vehicle cost and the company's material costs. Furthermore, fewer materials can reduce the overall vehicle failure rate.

[0127] It should be noted that the engine assembly in this application is applicable to both hybrid vehicles and pure gasoline vehicles, and no further restrictions are imposed here.

[0128] In some embodiments of this application, the vehicle further includes a battery assembly disposed in the vehicle chassis.

[0129] By placing the engine assembly and battery pack in different areas of the vehicle and storing fuel within the engine housing 100, more space is available for the battery pack on the vehicle chassis, allowing for a larger battery capacity and thus enhancing the vehicle's electric range.

[0130] Specifically, compared to existing technologies where both the fuel tank and battery pack are located on the vehicle chassis, this application stores fuel within the engine housing 100, with the engine located in the front compartment of the vehicle. This frees up the space occupied by the fuel tank 20 in the chassis of current hybrid vehicles, thereby facilitating an increase in the size of the battery pack. On the one hand, this increases the electric range of the hybrid vehicle; on the other hand, the battery pack has a longer fit with the vehicle floor. Compared to current integrated body, chassis, and battery technology, this further increases the torsional rigidity of the vehicle and improves overall vehicle safety performance.

[0131] Furthermore, by storing fuel within the engine housing 100 in the front compartment of the vehicle, passenger space can be freed up, thereby facilitating the fulfillment of customer needs in terms of vehicle passenger space.
