DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor fall within the protection scope of the present application.

[0043] In the related art, the oil sump of the engine adopts a double-oil-tank arrangement, which can effectively ensure the normal lubrication function of the engine during the climbing or descending process of the vehicle. In order to ensure the normal flow of the lubricating liquid, an oil pump is arranged on each oil tank, resulting in a complex structure and high cost.

[0044] In view of this, the present application provides an engine 100, Figures 1 to 6 is a structural schematic diagram of an embodiment of the engine 100 provided by the present application. The engine 100 provided by the present application has a simple structure and reduced cost. The engine 100 will be described in detail below with reference to the main drawings.

[0045] According to a first aspect of the present application, with reference to Figures 1 to 4 The present application provides an engine 100. The engine 100 comprises a housing 10 and a pump body 20. The housing 10 is formed with a first cavity 11 and a second cavity 12, and the first cavity 11 and the second cavity 12 are configured to store lubricating liquid. The pump body 20 is connected to the first cavity 11 and the second cavity 12 respectively, and is used to deliver the lubricating liquid in at least one of the first cavity 11 and the second cavity 12 to an engine cylinder 30.

[0046] In the technical solution of the present application, the shell 10 is formed with a first cavity 11 and a second cavity 12, which are configured to store lubricating liquid; by providing the first cavity 11 and the second cavity 12, it can be ensured that the lubricating liquid can smoothly enter the engine cylinder block 30 during climbing or descending, and the normal lubrication function of the engine 100 is ensured; at the same time, the pump body 20 is connected to the first cavity 11 and the second cavity 12 respectively, and is used to deliver the lubricating liquid in at least one of the first cavity 11 and the second cavity 12 to the engine cylinder block 30, and the pump body 20 is provided to be connected with the first cavity 11 and the second cavity 12 at the same time, which ensures that the lubricating liquid can normally enter the engine cylinder block 30, improves the utilization rate of parts compared with the related art, saves costs, and solves the technical problems of complex structure and high cost of the engine 100 in the related art.

[0047] It should be noted that due to the current performance improvement of vehicles, users' definition of vehicles is not only as a traffic tool, but also as a fashion appearance, powerful, off-road, urban and various purposes. It can also support users to challenge various net red slopes, or rush up the slope in Alashan Desert, and challenge the limit of personal and vehicle. Based on the above needs of people for vehicles, the current vehicle lubrication system design cannot effectively support the lubrication function of the engine 100 on special roads, which is easy to cause the risk of dry grinding of the engine cylinder block 30. The current vehicle climbing is mainly in the following ways: the first is to adopt a dry oil pan scheme, completely separate the engine 100 lubrication system design, the engine 100 is not designed to store oil tank, this design scheme can effectively improve the vehicle climbing degree, which is commonly used in racing cars, but not popular in conventional passenger cars, and the lubrication system is designed separately, which has high cost and is difficult to implement in passenger cars. The second is to arrange on one side, increase and deepen the oil pan oil storage space, and optimize the oil suction port position. This design scheme can improve the vehicle climbing degree, but it still cannot completely solve the problem of small vehicle climbing degree. This design cannot be used in low chassis vehicles, which will lower the lowest point of the vehicle chassis and affect the vehicle passability, and is easy to cause oil stirring risk when the vehicle is at a large inclination angle. The third is to arrange the powertrain with an inclination angle when the vehicle is arranged vertically. This arrangement scheme is commonly used in commercial vehicles and mini trucks. This scheme will lower the lowest point of the vehicle chassis in the passenger car arrangement, and cannot completely solve the problem of effective lubrication of the vehicle at a large climbing angle. The engine 100 provided in the present application has a first cavity 11 and a second cavity 12 formed in the shell 10, and the double-cavity structure can realize the extreme climbing of the vehicle. Under the condition that the vehicle power performance meets the requirements, the vehicle can meet the climbing requirements in various situations.

[0048] It should be noted that the formation of the first cavity 11 and the second cavity 12 is not limited. For example, in some embodiments, the housing 10 has a first part 102, a second part 103, and a third part 104. The first part 102 and the second part 103 are located on the same side of the third part 104 and are respectively connected to the third part 104. The first part 102 and the second part 103 protrude from the third part 104. The first part 102 forms the first cavity 11, and the second part 103 forms the second cavity 12. Further, the first part 102 includes a separately disposed first sub-shell 13 and a second sub-shell 14, which are detachably connected; such as Figure 2 As shown, the end of the first sub-shell 13 facing the second sub-shell 14 has multiple first through holes, and the end of the second sub-shell 14 facing the first sub-shell 13 has multiple second through holes corresponding to the first through holes. In actual installation, the second sub-shell 14 is aligned with the first sub-shell 13, so that the first through holes on the first sub-shell 13 correspond to the second through holes on the second sub-shell 14. Bolts pass through the first and second through holes in sequence, engaging with fasteners to fix the first sub-shell 13 and the second sub-shell 14. This design facilitates cleaning and maintenance of the engine 100. For example, if the second sub-shell 14 is deformed or damaged in a collision, it can be directly removed and replaced with a new one, without replacing the entire engine 100. Furthermore, if the lubricant in the first cavity 11 accumulates impurities after prolonged use, the second sub-shell 14 can be removed from the first sub-shell 13 to clean the impurities in the first cavity 11, thus ensuring the lubricant's functionality.

[0049] Furthermore, in some embodiments, since the first cavity 11 contains lubricating fluid, a sealing element is also provided between the first sub-shell 13 and the second sub-shell 14 to ensure sealing, thereby preventing lubricating fluid from leaking between the first sub-shell 13 and the second sub-shell 14 and reducing the risk of oil leakage. Even further, the sealing element is a sealing gasket.

[0050] In some embodiments, the first sub-shell 13 has a first chamber 15, and the second sub-shell 14 has a second chamber 16; the first cavity includes the first chamber 15 and the second chamber 16 that are interconnected. It should be noted that the volumes of the first chamber 15 and the second chamber 16 are not limited and can be selected according to actual conditions. For example, the first chamber 15 and the second cavity 12 may have the same volume, and the first chamber 15 and the second chamber 16 may be configured with completely equal volumes. Alternatively, the first chamber 15 and the second chamber 16 may be configured with non-equal volumes, where the volume of the first chamber 15 is greater than the volume of the second chamber 16, or the volume of the first chamber 15 is smaller than the volume of the second chamber 16.

[0051] In some embodiments, the second sub-shell 14 is provided in plurality, the plurality of second sub-shells 14 have different volumes, and the second chambers 16 in the plurality of second sub-shells 14 also have different volumes due to the different volumes of the plurality of second sub-shells 14; the first sub-shell 13 is connectable with one of the second sub-shells 14 having different volumes. In this way, the engine 100 can meet different models of vehicles, and at the same time, different working conditions can also be met. For example, when the vehicle is passing through a road with a large slope, the second sub-shell 14 can be disassembled according to the lubrication requirement of the engine 100, and a second sub-shell 14 with a larger volume is replaced, and the large-volume second sub-shell is matched with the first sub-shell, so that the first chamber 15 is connected to the large-volume second chamber 16, thereby achieving the purpose of increasing the volume of the first cavity 11, facilitating later modification and maintenance.

[0052] The first sub-shell 13 and the second sub-shell 14 are provided in a detachable manner, and the later maintenance cost can also be reduced. When the bottom of the engine 100 of the vehicle is expanded and scratched, the detachable arrangement of the first sub-shell 13 and the second sub-shell 14 can effectively protect the upper end of the engine 100 from being damaged, and only the second sub-shell 14 needs to be replaced, thereby reducing the later maintenance cost.

[0053] In order to ensure the structural strength, in some embodiments, please refer to Figure 3 The side of the second sub-shell 14 away from the first sub-shell 13 is provided with a plurality of reinforcing structures 141. Further, the reinforcing structure 141 can be a reinforcing rib.

[0054] The second part 103 is formed with the second cavity 12, and the second part 103 includes a third sub-shell and a fourth sub-shell provided in a split manner, and the third sub-shell and the fourth sub-shell are detachably connected; the third sub-shell is connected with the third part 104, and the third sub-shell has a third chamber, and the fourth sub-shell has a fourth chamber; the second cavity 12 includes the third chamber and the fourth chamber connected with each other. The arrangement and connection manner of the third sub-shell and the fourth sub-shell are the same as those of the first sub-shell 13 and the second sub-shell 14, and the third sub-shell and the fourth sub-shell are referred to the first sub-shell 13 and the second sub-shell 14, which will not be described here.

[0055] Please refer to Figure 1 and Figure 2 The engine 100 further includes an oil suction pipe 40, and the oil suction pipe 40 is used to convey the lubricating liquid in the first cavity 11 or the second cavity 12 to the pump body 20. Specifically, one end of the oil suction pipe 40 is connected to the pump body 20, and the other end of the oil suction pipe 40 is connected to the first cavity 11 and the second cavity 12.

[0056] Specifically, please continue to refer to Figure 2In the embodiment, the first cavity 11 and the second cavity 12 have oil outlets, the first cavity 11 and the second cavity 12 are respectively formed with openings at one end of the pump body, the openings are the oil outlet of the first cavity 11 and the oil outlet of the second cavity 12, the pump body 20 is formed with an oil suction port at one end of the shell, the oil suction pipe 40 includes a main pipe body and two branch pipe bodies, one end of the two branch pipe bodies is connected to one end of the main pipe body, the other end of the two branch pipe bodies is connected to the oil outlet of the first cavity 11 or the second cavity 12, and the other end of the main pipe body is connected to the oil suction port of the pump body 20. The pump body 20 is communicated with the first cavity 11 and the second cavity 12 through the oil suction pipe 40, so that one pump body 20 is used to control two cavities (i.e. the first cavity 11 and the second cavity 12), the utilization rate of parts is improved, and cost is saved.

[0057] It should be noted that the arrangement of the pump body 20, the oil suction pipe 40, the first cavity 11 and the second cavity 12 is not limited, and can be selected according to actual conditions.

[0058] In some embodiments, referring to Figure 2 and Figure 3 , the engine 100 includes one pump body 20 and at least one oil suction pipe 40, specifically, the pump body 20 is arranged at the oil outlet of the first cavity 11, the oil suction port of the pump body 20 is directly connected to the oil outlet of the first cavity 11, and the oil suction port of the pump body 20 is also connected to the oil outlet of the second cavity 12 through at least one oil suction pipe 40. By arranging in this way, one pump body 20 is used to control two cavities (i.e. the first cavity 11 and the second cavity 12), the utilization rate of parts is improved, and cost is saved.

[0059] Further, the connection mode of the pump body 20 and the shell 10 is not limited, as long as the pump body 20 can absorb the lubricating liquid in the first cavity 11 and the second cavity 12. Referring to Figure 2 , the oil suction port of the pump body 20 coincides with the oil outlet of the first cavity 11, one end of the oil suction pipe 40 is connected to the pump body 20, and the other end of the oil suction pipe 40 coincides with the oil outlet of the second cavity 12. In order to ensure the liquid suction effect, one end of the pump body 20 (the end provided with the oil suction port) can extend into the first cavity 11 through the oil outlet of the first cavity 11, and the other end of the oil suction pipe 40 extends into the second cavity 12 through the oil outlet of the second cavity 12.

[0060] In some embodiments, the engine 100 further comprises a pump body 20 and at least one oil suction pipe 40, and the pump body 20 is arranged between the first cavity 11 and the second cavity 12, and the oil suction port of the pump body 20 is communicated with the oil outlet of the first cavity 11 through the at least one oil suction pipe 40, and the oil suction port of the pump body 20 is also communicated with the oil outlet of the second cavity 12 through the at least one oil suction pipe 40. In this way, the two cavities (i.e. the first cavity 11 and the second cavity 12) are controlled by using one pump body 20, thereby improving the utilization rate of parts and saving costs.

[0061] In some embodiments, the engine 100 further comprises a control valve and a controller, the control valve is used to control the opening and closing of the pump body 20 and at least one of the first cavity 11 and the second cavity 12, and the control valve is electrically connected to the controller, and the controller is used to control the operation of the control valve. Specifically, the control valve controls the pump body 20 to communicate with the first cavity 11, and the pump body 20 absorbs the lubricating liquid in the first cavity 11 for lubrication of the engine 100, and when the lubricating liquid in the first cavity 11 is less, the control valve controls the pump body 20 to be disconnected from the first cavity 11, and at the same time controls the pump body 20 to communicate with the second cavity 12, and the pump body 20 absorbs the lubricating liquid in the second cavity 12 for lubrication of the engine 100. When the vehicle is in a special working condition, the control valve can also control the valve body to simultaneously communicate with the first cavity 11 and the second cavity 12, and the pump body 20 simultaneously absorbs the lubricating liquid in the first cavity 11 and the second cavity 12 for lubrication of the engine 100.

[0062] Further, in the present embodiment, the control valve is an electromagnetic valve.

[0063] In some embodiments, please continue to refer to Figure 3 , the engine 100 further comprises a sensor 50, and the sensor 50 is electrically connected to the controller, and the controller is used to receive the signal transmitted by the sensor 50, and the specific position of the sensor 50 is not limited and can be selected according to the actual situation.

[0064] In an embodiment, the sensor 50 is arranged in the first cavity 11, and the sensor 50 is used to monitor the lubricating liquid in the first cavity 11 and generate an oil amount signal, and the sensor 50 transmits the oil amount signal to the controller, and the controller controls the control valve according to the oil amount signal, so that the pump body 20 communicates with or is disconnected from the first cavity 11.

[0065] In some other embodiments, the sensor 50 is also arranged in the second cavity 12, and the sensor 50 is used to monitor the lubricating liquid in the second cavity 12 and generate an oil amount signal, and the sensor 50 transmits the oil amount signal to the controller, and the controller controls the control valve according to the oil amount signal, so that the pump body 20 communicates with or is disconnected from the second cavity 12.

[0066] In some embodiments, a sensor 50 is arranged in each of the first cavity 11 and the second cavity 12, and the sensor 50 is configured to monitor the lubricating oil in the first cavity 11 and the second cavity 12 and transmit an oil amount signal to the controller, and the controller is configured to control the control valve according to the oil amount signal so that the pump body 20 is in communication with the first cavity 11 or the second cavity 12.

[0067] It should be noted that the specific type of the sensor 50 is not limited, and can be selected according to actual conditions. In the present embodiment, the sensor 50 is a liquid level sensor 50, which is configured to monitor the liquid level of the lubricating oil in the first cavity 11 and the second cavity 12.

[0068] Specifically, when the vehicle is in normal driving and the engine 100 is in the first state, the controller controls the control valve to communicate the first cavity 11 and the pump body 20, and the pump body 20 absorbs the lubricating oil in the first cavity 11 for lubricating the engine 100.

[0069] When the vehicle is in a climbing state and the oil amount of the lubricating oil in the first cavity 11 is low, the engine 100 triggers the second state. When the oil amount of the lubricating oil in the first cavity 15 is lower than a preset oil amount, the sensor 50 transmits an oil amount signal to the controller, and the controller controls the control valve so that the pump body 20 is disconnected from the first cavity 11, and the controller also controls the control valve so that the pump body 20 is in communication with the second cavity 12, and the pump body 20 absorbs the lubricating oil in the second cavity 12 for lubricating the engine 100. When the oil amount of the lubricating oil in the second cavity 12 is reduced, the engine 100 also triggers the second state. When the oil amount of the lubricating oil in the second cavity 16 is lower than a preset oil amount, the sensor 50 transmits an oil amount signal to the controller, and the controller controls the control valve so that the pump body 20 is disconnected from the second cavity 12, and the controller also controls the control valve so that the pump body 20 is in communication with the first cavity 11, and the pump body 20 absorbs the lubricating oil in the first cavity 15 for lubricating the engine 100.

[0070] When the engine 100 is in the third state, the first cavity 11 and the second cavity 12 simultaneously meet the oil supply condition, and the pump body 20 is in communication with the first cavity 11 and the second cavity 12 at the same time.

[0071] In some embodiments, referring to Figure 4 , the housing 10 further comprises a communication channel 101, and the communication channel 101 communicates the first cavity 11 and the second cavity 12. In the present embodiment, the communication channel 101 is configured to flow the lubricating oil in the first cavity 11 to the second cavity 12 or flow the lubricating oil in the second cavity 12 to the first cavity 11 when the housing 10 is inclined relative to the horizontal plane.

[0072] In some embodiments, the position of the communication passage 101 needs to be set upward and cannot be set at the bottom of the first cavity 11 and the second cavity 12, because the lower side of the shell 10 generally needs to be provided with a crankshaft, and when the communication passage 101 is located at the bottom of the first cavity 11 and the second cavity 12, the space of the crankshaft is occupied, so that the crankshaft cannot be normally arranged, thereby causing the overall size of the shell to be increased.

[0073] It should be noted that the specific type of the communication passage 101 is not limited, as long as the first cavity 11 and the second cavity 12 can be communicated, for example, in some embodiments, the communication passage 101 can be a connecting pipe. In some other embodiments, the shell 10 has a first part 102, a second part 103 and a third part 104, the first part 102 and the second part 103 are arranged on the same side of the third part 104 and are connected with the third part 104 respectively, and the first part 102 and the second part 103 protrude from the third part 104; the communication passage 101 is arranged on the third part 104, and the first cavity 11 and the second cavity 12 are arranged on the first part 102 and the second part 103 respectively.

[0074] It should be noted that the diameter of the communication passage 101 is selected according to the actual oil supply amount, and the communication passage 101 can be designed to be integrated inside the shell 10, and the crankshaft maximum envelope avoidance design is needed when designing. The crankshaft maximum envelope avoidance design can be referred to the conventional setting mode in the art, which will not be described here.

[0075] The slope of the urban road is 0% to 10%, and the commonly used slope is 5%. The 10% slope belongs to a large slope in the urban road, and the maximum slope in the city is generally the slope of the underground parking lot entrance. The underground garage entrance that feels very steep in the subjective feeling has an actual slope of 15%, that is, 8.6°. The climbing slope of a family sedan is about 32%, and the four-wheel drive type can be slightly improved, but still does not exceed 40%. The climbing slope of the urban SUV is similar to that of the sedan, and the performance of the better one can reach a slope of 46%. The vehicle climbing slope is greatly affected by the overall power performance, tire performance, front and rear drive arrangement and the like. Since the sedan and the urban SUV have low requirements for the vehicle climbing slope, the engine 100 oil pan of this type of vehicle adopts Figure 1 The structure, the overall Z direction of the engine 100 is relatively flat, and this structure can meet the normal lubrication function of the engine 100 on the commonly used slope of the urban road.

[0076] In order to improve the overall vehicle climbing slope, the engine 100 oil pan of the longitudinal off-road vehicle type adopts a deepened oil collecting groove and a single-sided arrangement scheme. This arrangement scheme can greatly improve the climbing slope of the off-road vehicle, and the market optimal part of the vehicle can even complete 100% (45°) climbing.
