[0046] The following describes an oil supply assembly 1 according to an embodiment of the present invention with reference to the accompanying drawings. The oil supply assembly 1 is used to supply oil to an engine.

[0047] like Figure 1-Figure 3 As shown, the oil supply assembly 1 according to the embodiment of the present invention includes a housing 100 .

[0048] The housing 100 is constructed as a part of the engine. A first chamber 21 is provided in the housing 100. The first chamber 21 is used to contain fuel. Moreover, the first chamber 21 is suitable for being connected to the engine through an oil circuit to provide 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, thereby reserving more space for other components on the vehicle chassis.

[0049] The oil circuit may be an independent oil channel or an integrated plurality of oil channels, and no excessive restrictions are imposed here.

[0050] Specifically, the fuel tank in the related art is arranged on the chassis of the vehicle, and the engine is arranged in the front compartment of the vehicle. The fuel tank occupies a large space on the chassis of the vehicle. By storing the fuel in the engine casing, there is no need to reserve space for fuel storage on the chassis of the vehicle, which makes it easier to reserve more space for components on the chassis of the vehicle.

[0051] In addition, by setting the fuel in the engine housing 100, the fuel and the engine are set closer, so as to improve the integration between the engine and the fuel, and facilitate the fuel to enter the engine. This makes it easy to reduce the length of the oil circuit, reduce the space occupied by the oil circuit on the vehicle, and make the overall vehicle layout more concise and beautiful.

[0052] Therefore, the fuel supply assembly 1 according to the embodiment of the present invention stores the fuel in the engine housing 100, so that there is no need to reserve space for the fuel storage on the vehicle chassis, thereby reserving more space for other components on the vehicle chassis.

[0053] The oil supply assembly 1 according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0054] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the oil supply assembly 1 includes a housing 100 .

[0055] In some embodiments of the present invention, Figure 1 , Figure 2 As shown, the fuel supply assembly 1 also includes a fuel pump 32, which is connected to the combustion chamber of the engine through a first oil pipe and is used to pump fuel into the combustion chamber of the engine to provide fuel to the engine so that the fuel can be mixed with air in the combustion chamber and ignited, thereby enabling the engine to output driving force to the outside.

[0056] The first oil pipeline may be an independent pipeline or a plurality of integrated oil pipelines, and no excessive restrictions are imposed here.

[0057] In some optional embodiments of the present invention, a 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 to the engine so that the fuel can be mixed with air in the combustion chamber and ignited, thereby enabling the engine to output driving force to the outside.

[0058] In addition, by setting the fuel pump 32 in the first chamber 21, the fuel pump 32 and the engine are integrated, which makes it convenient for the fuel to enter the engine, reduces the length of the first oil pipe, reduces the space occupied by the first oil pipe on the vehicle, and makes the layout of the entire vehicle more concise and beautiful.

[0059] In some embodiments, the housing 100 is constructed as an oil pan of the 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 expand the size of the oil pan due to the need to dispose the fuel pump 32.

[0060] In some other optional embodiments of the present invention, a second chamber 22 is further provided in the shell 100. The second chamber 22 is provided outside the first chamber 21, and the second chamber 22 is communicated with the first chamber 21. A fuel pump 32 is provided 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 to the engine, so that the fuel can be mixed with air in the combustion chamber and ignited, thereby enabling the engine to output driving force to the outside.

[0061] In addition, by setting the fuel pump 32 in the second chamber 22, the fuel pump 32 and the engine are integrated, which makes it convenient for the fuel to enter the engine, reduces the length of the first oil pipe, reduces the space occupied by the first oil pipe on the vehicle, and makes the overall layout of the vehicle more concise and beautiful.

[0062] In some embodiments, Figure 3As shown, the first side wall 203 of the first chamber 21 separates the first chamber 21 from the second chamber 22. An oil through hole is provided at the lower portion of the first side wall 203, and the oil through hole connects the first chamber 21 and the second chamber 22. The fuel in the first chamber 21 can enter the second chamber 22 through the oil through hole, and the fuel pump 32 can pump the fuel in the first chamber 21 and / or the second chamber 22 into the combustion chamber of the engine.

[0063] By connecting the first chamber 21 and the second chamber 22 through the oil hole, the fuel can be stored in the first chamber 21 and the second chamber 22 at the same time, so as to increase the fuel storage capacity of the housing 100.

[0064] 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 oil through hole and affecting the oil flow efficiency of the first chamber 21 and the second chamber 22 .

[0065] In some specific embodiments of the present invention, Figure 2 As shown, the housing 100 is provided with a first through hole 24 , and the refueling pipe 41 is communicated with the first chamber 21 or the second chamber 22 through the first through hole 24 , so as to transport fuel to the first chamber 21 or the second chamber 22 .

[0066] 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 refueling hole of the vehicle. 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 fuel to the first chamber 21 or the second chamber 22.

[0067] In some embodiments, Figure 2 As shown, the fuel supply assembly 1 also includes a fuel filler pipe joint 43 and a clamp 42. The fuel filler pipe joint 43 is fixed to the first through hole 24. The fuel filler pipe 41 is sleeved on the fuel filler pipe joint 43 and communicated with the first through hole 24. The clamp 42 extends along the circumference of the fuel filler pipe 41 to apply a tightening force to the fuel filler pipe 41, so that one end of the fuel filler pipe 41 can be fixed on the fuel filler pipe joint 43, so that external fuel can enter the first chamber 21 or the second chamber 22 through the fuel filler pipe 41 and the first through hole 24 to replenish the first chamber 21 or the second chamber 22 with fuel.

[0068] In some examples, the refueling pipe connector 43 is threadedly connected to and communicates with the first through hole 24 .

[0069] In other embodiments, the refueling pipe connector 43 is fixed to the housing 100 by a first fastener, so that the refueling pipe connector 43 is connected to the first through hole 24 .

[0070] The first fastener may be a screw, a pin or other parts.

[0071] In some embodiments of the present invention, a wave-breaking plate is provided in the first chamber 21 to suppress fuel sloshing, so that the sloshing of the fuel can be reduced during the driving of the vehicle, thereby reducing the impact of the fuel on the housing 100.

[0072] In some embodiments of the present invention, an oil float is provided in the first chamber 21, and 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.

[0073] In some embodiments of the present invention, Figure 2 , Figure 3 As shown, a third chamber 11 is provided in the housing 100, and the third chamber 11 has a first open port 111. The third chamber 11 is used to contain engine oil to provide lubrication for the engine, wherein the lubricating oil in the engine will flow from the first open port 111 to the third chamber 11 under the action of gravity to store the engine oil, thereby realizing the circulation of the engine oil in the third chamber 11 and the engine, so as to utilize the engine oil to lubricate the engine.

[0074] In some optional embodiments of the present invention, an oil pump 31 is provided in the third chamber 11, and the oil pump 31 is connected to the lubricating oil channel of the engine through a second oil pipe to pump the oil in the third chamber 11 to the lubricating oil channel of the engine, so that the oil in the third chamber 11 can flow along the lubricating oil channel to the area of ​​the engine that needs lubrication, thereby achieving lubrication of the engine.

[0075] The oil pump 31 is arranged in the third chamber 11, so as to facilitate the integration of the oil pump 31 and the engine, reduce the length of the second oil pipe, reduce the space occupied by the second oil pipe on the vehicle, and facilitate making the layout of the whole vehicle more concise and beautiful.

[0076] Among them, the lubricating oil channel can be an independent oil channel or a plurality of integrated oil channels, and the second oil pipe can be an independent oil pipe or a plurality of integrated oil pipes, and no excessive restrictions are made here.

[0077] 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 lubricating oil channel to the area of ​​the engine that needs lubrication. Under the action of gravity, the oil attached to the surface of the engine will flow into the third chamber 11 to achieve the circulation of the oil and thereby achieve sufficient lubrication of the engine.

[0078] In some optional embodiments of the present invention, 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 fully utilize the space in the engine, thereby reducing the occupied space of the first chamber 21 and the third chamber 11.

[0079] In some embodiments, the first chamber 21 has a second opening 211 , and the first cover 202 is disposed on the second opening 211 . When the engine oil flows onto the first cover 202 , the engine oil can flow along the first cover 202 into the third chamber 11 .

[0080] In some embodiments, the shell 100 is an integrally molded part, and a shell 100 can be molded by plastic. The shell 100 has a first chamber 21 and a third chamber 11. The shell 100 has a partition to separate the space inside the shell 100 into the third chamber 11 and the first chamber 21.

[0081] Among them, the irregular third chamber 11 and the first chamber 21 are formed conveniently through plastic molding to adapt to the placement space of the shell 100, thereby making full use of the placement space and increasing the volume of the third chamber 11 and the first chamber 21 to store more engine oil and fuel.

[0082] In other embodiments, Figure 1 As shown, 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 fixed together after being separately molded, which makes it easy to reduce the molding difficulty and improve the flexibility of the layout of the oil tank 10 and the fuel tank 20.

[0083] In some optional embodiments of the present invention, the third chamber 11 is provided with a second through hole 12 , and the second through hole 12 cooperates with the oil drain plug 44 , and the oil drain plug 44 is used to open or close the second through hole 12 .

[0084] When the engine needs to be repaired or maintained, the oil in the third chamber 11 needs to be drained to facilitate the operation of the engine. 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 discharged from the second through hole 12.

[0085] In some embodiments, the oil drain plug 44 is a magnetic component. When the engine is lubricated by engine oil, metal chips formed on the engine due to wear will gather in the third chamber 11 along with the oil. The oil drain plug 44 can absorb the metal chips and discharge them from the third chamber 11 when maintaining the engine.

[0086] In some embodiments, the second through hole 12 is disposed 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 residual oil in the third chamber 11.

[0087] In some optional embodiments of the present invention, the wall of the third chamber 11 is coated with a heat-insulating material. Since the engine will generate heat after working for a period of time, the temperature of the engine oil will also increase. By coating the wall of the third chamber 11 with a heat-insulating material, the heat inside the third chamber 11 can be isolated from the outside world to prevent excessive temperature from affecting the operation of other components in the vehicle.

[0088] In some embodiments of the present invention, the housing 100 is configured as an oil sump of an engine.

[0089] In some embodiments, an engine includes a housing body defining an interior cavity having a lower open opening.

[0090] In some examples, the housing 100 serves as an oil pan of the engine, and the housing 100 closes the lower opening, that is, the first chamber 21 and the third chamber 11 are both located in the inner cavity, and the engine oil in the engine 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.

[0091] In other examples, a portion of the housing 100 serves as an oil pan of the engine, and a portion of the housing 100 closes the lower opening, that is, the third chamber 11 is located in the inner cavity, and the first chamber 21 is located outside the inner cavity. The engine oil in the engine 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.

[0092] The engine assembly according to the embodiment of the present invention is described below. The engine assembly according to the embodiment of the present invention comprises the oil supply assembly 1 according to the above embodiment of the present invention.

[0093] According to the engine assembly of the embodiment of the present invention, the fuel is stored in the engine housing 100 by utilizing the fuel supply assembly 1 according to the above-mentioned embodiment of the present invention. In this way, 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.

[0094] In some embodiments of the present invention, the engine assembly includes a shell body, the shell body defines an inner cavity with a lower opening, and the oil supply assembly 1 is arranged below the shell body and closes the lower opening.

[0095] In some examples, the housing 100 serves as an oil pan of the engine, and the housing 100 closes the lower opening, that is, the first chamber 21 and the third chamber 11 are both located in the inner cavity, and the engine oil in the engine 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.

[0096] In other examples, a portion of the housing 100 serves as an oil pan of the engine, and a portion of the housing 100 closes the lower opening, that is, the third chamber 11 is located in the inner cavity, and the first chamber 21 is located outside the inner cavity. The engine oil in the engine 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.

[0097] In some embodiments of the present invention, the shell 100 includes a main body 201 and a first cover body 202. The main body 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 body 202 is covered on the second opening 211 to close the second opening 211 to prevent the fuel in the first chamber 21 from evaporating from the second opening 211.

[0098] In some embodiments, the lubricating oil in the inner cavity of the engine flows into the third chamber 11 from the first opening 111 under the action of gravity. The first cover 202 is provided to seal the second opening 211 to prevent the oil from entering the first chamber 21. When the oil flows onto the first cover 202, the first cover 202 guides the oil flow to the first opening 111.

[0099] In some examples, the first cover body 202 is a structure formed by casting or stamping, so that the first cover body 202 can close the second opening 211, so that the first chamber 21 forms a closed space.

[0100] In some optional embodiments of the present invention, Figure 2 As shown, the engine assembly also includes a first seal 61, which is located between the first cover body 202 and the edge of the second open port 211 to seal the gap between the first cover body 202 and the edge of the second open port 211 to completely seal the second open port 211, thereby avoiding volatilization of the fuel in the first chamber 21 and preventing objects in the outside from contaminating the fuel in the first chamber 21.

[0101] In some embodiments, Figure 2 As shown, the second opening 211 is the opening above the first chamber 21, the first cover body 202 is covered on 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 body 202, and the second fastener passes through the first cover body 202, the first sealing member 61 and the edge of the second opening 211 in sequence to fix the first cover body 202 and the first sealing member 61 on the main body 201, so that the first cover body 202 and the first sealing member 61 can fully seal the second opening 211.

[0102] The second fastener may be a screw, a pin or other parts.

[0103] In some optional embodiments of the present invention, the height of the first cover body 202 at one end close to the third chamber 11 is lower than that of the first cover body 202 at one end away from the third chamber 11, so that the first cover body 202 can guide the oil flowing thereon, thereby guiding the oil into the third chamber 11.

[0104] Specifically, when the oil flows onto the first cover 202 , the first cover 202 has a guiding effect on the flow of the oil, so as to guide the oil to the first open port 111 .

[0105] In some embodiments of the present invention, Figure 2 As shown, a second chamber 22 is further provided in the housing 100, and the second chamber 22 is communicated with the first chamber 21. A fuel pump 32 is provided in 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 to the engine, so that the fuel can be mixed with air in the combustion chamber and ignited, thereby enabling the engine to output driving force to the outside.

[0106] It should be explained here that the second chamber 22 can be a part of the first chamber 21, that is, the fuel pump 32 is arranged in the first chamber 21, and the second chamber 22 can also be a separate chamber, that is, the fuel pump 32 is arranged outside the first chamber 21.

[0107] In some optional embodiments of the present invention, the second chamber 22 is disposed outside the first chamber 21, and the fuel pump 32 is disposed in 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 to the engine, so that the fuel can be mixed with air in the combustion chamber and ignited, thereby enabling the engine to output driving force to the outside.

[0108] The second chamber 22 is disposed outside the first chamber 21 , and the fuel pump 32 is disposed inside the second chamber 22 , so that the fuel pump 32 can be easily taken out of the second chamber 22 or installed into the second chamber 22 .

[0109] In some embodiments, the first chamber 21 has a second open port 211, the first cover body 202 is covered on the second open port 211, the second chamber 22 has a third open port 221, and the second cover body 23 is covered on the third open port 221. When the fuel pump 32 needs to be inspected, it is only necessary to open the second chamber 22 without opening the first chamber 21. On the one hand, it can prevent debris from falling from the second open port 211 into the first chamber 21, and on the other hand, it is convenient to operate the fuel pump 32.

[0110] In some optional embodiments of the present invention, Figure 2 , Figure 3 As shown, the second chamber 22 has a third open port 221, and the fuel pump 32 is suitable for being arranged in the second chamber 22 from the third open port 221. A second cover body 23 is provided on the fuel pump 32, and the second cover body 23 is used to close the third open port 221 to prevent the fuel from volatilizing from the third open port 221, to prevent objects in the external environment from entering the second chamber 22 from the third open port 221, and to prevent the fuel in the second chamber 22 and the first chamber 21 from being contaminated.

[0112] In addition, by fixing the second cover body 23 to the fuel pump 32, the fuel pump 32 and the second cover body 23 can be installed in place at the same time, which is convenient for reducing the installation steps.

[0113] In some embodiments, when the second cover body 23 cooperates with the edge of the hole of the third opening 221, the second cover body 23 is subjected to the downward gravity of the fuel pump 32 so that the second cover body 23 and the edge of the hole of the third opening 221 can fully fit together, thereby enhancing the sealing of the second cover body 23 to the third opening 221.

[0114] In some specific embodiments of the present invention, the second chamber 22 is disposed in the first chamber 21 , that is, the fuel pump 32 is located in the first chamber 21 , so that the fuel pump 32 does not occupy additional space, which facilitates the miniaturization design of the housing 100 .

[0115] In the embodiment where the housing 100 is configured as an oil pan of an engine, the fuel pump 32 is located in the first chamber 21 , so that the size of the oil pan does not need to be enlarged due to the need to provide the fuel pump 32 .

[0116] In some embodiments, the first cover 202 has a notch, which defines a third opening 221 , and the fuel pump 32 is suitable for being installed into the second chamber 22 through the notch. The second cover 23 is covered on the notch to close the notch.

[0117] Among them, when it is necessary to remove the fuel pump 32, it is only necessary to open the second cover body 23 in the gap, without operating the first cover body 202, and without opening the first chamber 21. On the one hand, it is convenient to reduce the probability of debris falling into the first chamber 21, and on the other hand, it is convenient to remove the fuel pump 32 and to inspect the fuel pump 32.

[0118] In some examples, a portion of the first cover 202 is recessed toward the bottom wall of the first chamber 21 to define a gap, and the side wall of the gap is located in the first chamber 21 , that is, the gap is located in the first chamber 21 and the second chamber 22 is located in the first chamber 21 .

[0119] 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 into the second chamber 22 through the third through hole, and the second cover 23 is disposed on the third through hole to close the third through hole.

[0120] Among them, 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, without operating the first cover body 202, and without opening the first chamber 21. On the one hand, it is convenient to reduce the probability of debris falling into the first chamber 21, and on the other hand, it is convenient to remove the fuel pump 32 and to inspect the fuel pump 32.

[0121] In some specific embodiments of the present invention, Figure 2 As shown, the engine assembly also includes a second seal 62, which is arranged between the second cover body 23 and the edge of the third open port 221, and is used to seal the gap between the second cover body 23 and the edge of the third open port 221 to completely seal the third open port 221, thereby facilitating the reduction of volatilization of the fuel in the second chamber 22 and preventing objects in the outside from contaminating the fuel in the second chamber 22.

[0122] In some examples, such as Figure 2 As shown, the second sealing member 62 is located above the edge of the third opening 221, the second cover body 23 is located above the second sealing member 62, and the third fastener passes through the second cover body 23, the second sealing member 62 and the edge of the third opening 221 in sequence to fix the second cover body 23 and the second sealing member 62 to the top of the second chamber 22, so that the second cover body 23 and the second sealing member 62 can fully close the third opening 221.

[0123] The third fastener may be a screw, a pin or other parts.

[0124] In some specific embodiments of the present invention, the shell 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 shell 100 on the shell body, the fuel tank 20 and the oil tank 10 can be fixed at the bottom of the shell body at the same time, and there is no need to install the fuel tank 20 and the oil tank 10 separately, which is convenient for reducing the work station and assembly time for assembling the fuel tank 20 in the vehicle assembly process, simplifying the process sequence and assembly personnel configuration, and reducing costs for the enterprise.
