[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] Reference below Figure 1-Figure 3 The oil communication device 100 according to the embodiment of the present invention is described. The oil communication device 100 is connected between the oil pump 200 and the main flow channel of the engine 400.

[0037] like Figure 1-Figure 2As shown, an oil communication device 100 for an engine 400 according to an embodiment of the present invention comprises: a device body 1, the device body 1 having an oil inlet 11 and an oil outlet 12, an oil channel 13 formed in the device body 1, the oil channel 13 connecting the oil inlet 11 and the oil outlet 12, the oil inlet 11 being used to communicate with an oil pump 200 of the engine 400, and the oil outlet 12 being used to communicate with a main oil channel 300 of the engine 400; a heating element 2, the heating element 2 being sleeved on the device body 1, and the heating element 2 being used to heat the oil in the oil channel 13.

[0038] Among them, along the extension direction of the oil channel 13, that is, Figure 1 In the X direction, the device body 1 may have two opposite ends, one end of the device body 1 has an oil inlet 11, and the other end of the device body 1 has an oil outlet 12. An oil channel 13 is formed in the device body 1, so that the oil channel 13 can connect the oil inlet 11 and the oil outlet 12, so that the oil can flow into the oil channel 13 from the oil inlet 11, and then flow out of the oil channel 13 from the oil outlet 12. As some embodiments of the present application, the cross-section of the oil channel 13 may be circular. As some embodiments of the present application, the cross-section of the oil channel 13 may be polygonal. The present application takes the cross-sectional structure of the oil channel 13 as a circle as an example for explanation, and such a setting can make the layout of the oil channel 13 reasonable and reduce the risk of eddy currents in the oil channel 13. As some embodiments of the present application, the oil channel 13 can be constructed as a straight channel. Such a configuration can make the layout of the oil channel 13 reasonable, which is beneficial to further reduce the risk of eddy currents in the oil channel 13, and is also beneficial to reduce the travel of the oil in the oil channel 13, thereby saving the energy consumption of the oil pump 200, and further facilitating the low-energy consumption design of the vehicle.

[0039] Flanges 15 may be formed at both ends of the device body 1. As some embodiments of the present application, the flange 15 at one end close to the oil inlet 11 may be directly connected to the oil pump 200 of the engine 400 by bolts, so that the oil inlet 11 is directly connected to the oil pump 200 of the engine 400. As some embodiments of the present application, the flange 15 at one end close to the oil inlet 11 may be connected to a connecting pipe, and the end of the connecting pipe away from the flange 15 may be connected to the oil pump 200, so that the oil inlet 11 is indirectly connected to the oil pump 200 of the engine 400 through the connecting pipe. However, the present application is not limited thereto, as long as the oil inlet 11 is connected to the oil pump 200 of the engine 400, it is convenient for the oil pump 200 to pump the oil into the oil channel 13 through the oil inlet 11.

[0040] The flange 15 at one end close to the oil outlet 12 can be connected to the main oil channel 300 of the engine 400, so that the oil outlet 12 is connected to the main oil channel 300 of the engine 400, so that the oil in the oil channel 13 can flow into the main oil channel 300 through the oil outlet 12, and flow to the inside of the engine 400 through the main oil channel 300, so that the oil can play a lubricating role inside the engine 400.

[0041] As some embodiments of the present application, the heating element 2 can be constructed as a metal heating element, such as: a heating wire, a heating plate, etc. The heating element 2 is sleeved on the device body 1, so that the heating element 2 can be arranged around the device body 1, so that the heating element 2 can evenly heat the oil in the oil channel 13 along the circumference of the device body 1. As some embodiments of the present application, the heating element 2 and the device body 1 can be constructed as an integrally formed part. As some embodiments of the present application, the heating element 2 and the device body 1 can be connected by welding. The present application takes the integrally formed heating element 2 and the device body 1 as an example for explanation. The integrally formed part has good structural strength. By integrally forming the heating element 2 and the device body 1, the connection reliability of the heating element 2 and the device body 1 can be improved, and the probability of fracture at the connection between the heating element 2 and the device body 1 can be reduced, thereby improving the structural stability of the oil connecting device 100.

[0042] Furthermore, the integral molding of the heating element 2 and the device body 1 can reduce the number of molds, thereby reducing the production cost of the oil connecting device 100, and the integral molding of the heating element 2 and the device body 1 can also improve the heat exchange efficiency between the heating element 2 and the device body 1, which is beneficial for the heating element 2 to reliably heat the oil in the oil channel 13, thereby rapidly increasing the temperature of the oil, which is beneficial for reducing the viscosity of the oil, improving the fluidity of the oil, and effectively reducing the mechanical wear of parts in the engine 400, for example: reducing the wear of the friction pairs of the engine 400, which is beneficial for improving the response speed of the engine 400 start-up and the working reliability of the engine 400, thereby extending the service life of the vehicle.

[0043] Specifically, when the vehicle starts, the heating element 2 mounted on the device body 1 is powered on to increase the temperature. The oil in the oil pan 500 is pumped from the oil inlet 11 into the oil channel 13 under the action of the oil pump 200, so that the heating element 2 and the oil in the oil channel 13 exchange heat. The oil can absorb the heat of the heating element 2 to increase the temperature of the oil. The oil after the temperature is increased can flow into the main oil channel 300 through the oil outlet 12, and flow to the inside of the engine 400 through the main oil channel 300, so that the oil after the temperature is increased can play a lubricating role inside the engine 400. After the oil in the engine 400 is lubricated, it can fall back to the oil pan 500 under the action of gravity, thereby realizing the circulation of the oil.

[0044] Therefore, by arranging the heating element 2 to be sleeved on the device body 1, and the heating element 2 heats the oil in the oil channel 13, the temperature of the oil in the oil channel 13 can be increased, which is beneficial to reducing the viscosity of the oil and improving the fluidity of the oil, thereby reducing the mechanical wear of parts in the engine 400, which is beneficial to improving the working reliability of the engine 400, and further extending the service life of the vehicle.

[0045] In some embodiments of the present invention, Figure 3 As shown, the oil communication device 100 may also include: a first temperature detection component 4, which is arranged at the oil outlet 12, and is used to detect the oil temperature. The heating component 2 is configured to be turned on or off according to the detection information of the first temperature detection component 4.

[0046] Wherein, as some embodiments of the present application, the first temperature detection member 4 can be constructed as a mercury thermometer. As some embodiments of the present application, the first temperature detection member 4 can be constructed as an infrared sensor, and the infrared sensor can use the infrared energy radiated by the object to measure the temperature. As some embodiments of the present application, the first temperature detection member 4 can be connected to the device body 1 by bolts, so that the first temperature detection member 4 is arranged at the oil outlet 12, so that the first temperature detection member 4 detects the oil temperature at the oil outlet 12. As some embodiments of the present application, the first temperature detection member 4 can be connected to the device body 1 by snapping, so that the first temperature detection member 4 is arranged at the oil outlet 12, so that the first temperature detection member 4 detects the oil temperature at the oil outlet 12.

[0047] As some embodiments of the present application, the oil communication device 100 may further include a controller 6, and the heating element 2 and the first temperature detection element 4 may both be connected to the controller 6 in communication, so that the heating element 2 may be turned on or off according to the detection information of the first temperature detection element 4. The controller 6 receives the detection information of the first temperature detection element 4 in real time. When the vehicle is started, when the first temperature detection element 4 detects that the oil temperature at the oil outlet 12 is low and cannot meet the lubrication demand of the engine 400, the controller 6 controls the heating element 2 to turn on, so that the heating element 2 heats the oil in the oil channel 13. When the first temperature detection element 4 detects that the oil temperature at the oil outlet 12 continues to rise until the oil temperature meets the lubrication demand of the engine 400, the controller 6 controls the heating element 2 to turn off, so that the oil temperature at the oil outlet 12 always meets the lubrication demand of the engine 400, reduces the mechanical wear of the components in the engine 400, and thus improves the working reliability of the engine 400.

[0048] In some embodiments of the present invention, Figure 3As shown, the oil connecting device 100 may also include: a second temperature detection component 5, the second temperature detection component 5 is arranged at the oil inlet 11, the second temperature detection component 5 is used to detect the oil temperature, and the heating component 2 is configured to be turned on or off according to the detection information of the first temperature detection component 4 and the detection information of the second temperature detection component 5.

[0049] Wherein, as some embodiments of the present application, the second temperature detection member 5 can be constructed as a mercury thermometer. As some embodiments of the present application, the second temperature detection member 5 can be constructed as an infrared sensor, and the infrared sensor can use the infrared energy radiated by the object to measure the temperature. As some embodiments of the present application, the second temperature detection member 5 and the device body 1 can be connected by bolts so that the second temperature detection member 5 is arranged at the oil inlet 11, so that the second temperature detection member 5 detects the oil temperature at the oil inlet 11. As some embodiments of the present application, the second temperature detection member 5 and the device body 1 can be connected by snapping so that the second temperature detection member 5 is arranged at the oil inlet 11, so that the second temperature detection member 5 detects the oil temperature at the oil inlet 11.

[0050] As some embodiments of the present application, the oil communication device 100 may further include a controller 6, for example, the controller 6 may be constructed as an ECU (Engine Control Unit), and the heating element 2, the first temperature detection element 4, and the second temperature detection element 5 may all be connected to the controller 6 in communication, so that the heating element 2 may be turned on or off according to the detection information of the first temperature detection element 4 and the second temperature detection element 5. The controller 6 receives the detection information of the first temperature detection element 4 and the second temperature detection element 5 in real time. When the vehicle is cold-started, the second temperature detection element 5 detects that the oil temperature at the oil inlet 11 is low and cannot meet the lubrication requirements of the engine 400, the controller 6 controls the heating element 2 to turn on so that the heating element 2 heats the oil in the oil channel 13. When the vehicle is hot-started, the second temperature detection element 5 detects that the oil temperature at the oil inlet 11 is appropriate and meets the lubrication requirements of the engine 400, the controller 6 controls the heating element 2 to turn off to save energy consumption of the vehicle.

[0051] Furthermore, when the vehicle is cold-started, the second temperature detection element 5 detects that the oil temperature at the oil inlet 11 is low, and the controller 6 controls the heating element 2 to turn on, so that the heating element 2 heats the oil in the oil channel 13. After heating for a period of time, the oil temperature continues to rise, and when the first temperature detection element 4 detects that the oil temperature at the oil outlet 12 rises to the oil temperature that meets the lubrication demand of the engine 400, the controller 6 controls the heating element 2 to turn off, reducing the risk of the oil temperature entering the engine 400 being too high due to the continuous heating of the oil by the heating element 2, thereby reducing the risk of engine 400 failure caused by the engine 400 operating temperature being too high, which is conducive to improving the working reliability of the engine 400.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the oil communication device 100 may further include: a cooling member 3 , which is sleeved on the device body 1 and is used to cool the oil in the oil channel 13 .

[0053] Among them, as some embodiments of the present application, the cooling member 3 can be constructed as a metal cooling element, for example: a metal member with a cooling channel, etc. The cooling member 3 is sleeved on the device body 1, so that the cooling member 3 can be arranged around the device body 1, so that the cooling member 3 can evenly cool the oil in the oil channel 13 along the circumference of the device body 1. As some embodiments of the present application, the cooling member 3 and the device body 1 can be constructed as an integrally formed member. As some embodiments of the present application, the cooling member 3 and the device body 1 can be welded and connected. The present application takes the integral molding of the cooling member 3 and the device body 1 as an example for explanation. The integrally formed member has good structural strength. By integrally molding the cooling member 3 and the device body 1, the connection reliability of the cooling member 3 and the device body 1 can be improved, and the probability of fracture at the connection between the cooling member 3 and the device body 1 can be reduced, thereby improving the structural stability of the oil connecting device 100.

[0054] Furthermore, the integral molding of the cooling member 3 and the device body 1 can reduce the number of molds, thereby reducing the production cost of the oil connecting device 100, and the integral molding of the cooling member 3 and the device body 1 can also improve the heat exchange efficiency between the cooling member 3 and the device body 1, which is beneficial for the cooling member 3 to reliably cool the oil in the oil channel 13, thereby quickly reducing the temperature of the oil, effectively reducing the risk of high-temperature oil flowing into the engine 400 and causing the temperature of the engine 400 to be too high, which is beneficial to improving the working reliability of the engine 400, reducing the risk of engine 400 failure, and thus extending the service life of the vehicle.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the cooling member 3 has a heat exchange medium inlet 31 and a heat exchange medium outlet 32, and a heat exchange flow channel 33 is formed in the cooling member 3. The heat exchange flow channel 33 connects the heat exchange medium inlet 31 and the heat exchange medium outlet 32. The heat exchange flow channel 33 is arranged around the oil channel 13 along the circumference of the oil channel 13, and the heat exchange flow channel 33 and the oil channel 13 cooperate in heat exchange.

[0056] As some embodiments of the present application, along the axial direction of the heat exchange flow channel 33, the cooling member 3 may have two opposite ends, one end of the cooling member 3 has a heat exchange medium inlet 31, and the other end of the cooling member 3 has a heat exchange medium outlet 32. A heat exchange flow channel 33 is formed in the cooling member 3, so that the heat exchange flow channel 33 can connect the heat exchange medium inlet 31 and the heat exchange medium outlet 32, so that the heat exchange medium can flow into the heat exchange flow channel 33 from the heat exchange medium inlet 31, and then flow out of the heat exchange flow channel 33 from the heat exchange medium outlet 32. As some embodiments of the present application, the cross-section of the heat exchange flow channel 33 may be circular. As some embodiments of the present application, the cross-section of the heat exchange flow channel 33 may be polygonal. The present application takes the cross-sectional structure of the heat exchange flow channel 33 as a circle as an example for explanation, and such a setting can make the arrangement of the heat exchange flow channel 33 reasonable and reduce the risk of eddy currents in the heat exchange flow channel 33.

[0057] As some embodiments of the present application, the heat exchange medium may be cooling water. The heat exchange flow channel 33 and the oil channel 13 cooperate in heat exchange to reduce the temperature of the oil in the oil channel 13, thereby reducing the risk of high temperature oil flowing into the engine 400 and causing the engine 400 to be overheated. Along the circumference of the oil channel 13, the heat exchange flow channel 33 is arranged around the oil channel 13. Such an arrangement allows the heat exchange flow channel 33 to uniformly cool the oil in the oil channel 13 along the circumference of the oil channel 13, so that the temperature of the oil is uniformly reduced along the circumference of the oil channel 13, reducing the risk of cracking of the device body 1 due to uneven circumferential temperature of the oil channel 13, thereby extending the service life of the device body 1.

[0058] As some embodiments of the present application, the heat exchange flow channel 33 is arranged around the oil channel 13 along the circumference of the oil channel 13 so that the heat exchange medium can flow around the oil channel 13, which is beneficial for the heat exchange medium to uniformly cool the oil in the oil channel 13 around the oil channel 13.

[0059] In some embodiments of the present invention, Figure 3 As shown, an on-off valve 331 is provided in the heat exchange flow channel 33 , and the on-off valve 331 is configured to be opened or closed according to the oil temperature in the oil channel 13 .

[0060] In some embodiments of the present application, the on-off valve 331 may be configured as a solenoid valve. In some embodiments of the present application, the on-off valve 331 may be configured as a pressure valve. The on-off valve 331 is disposed in the heat exchange flow channel 33, and the on-off valve 331 is communicatively connected with the controller 6. The on-off valve 331 may be opened or closed according to the oil temperature in the oil channel 13, and further, the on-off valve 331 may be opened or closed according to the oil outlet 12 temperature.

[0061] When the heating element 2 is turned off, since the engine system will continuously generate heat during operation, the oil will continuously absorb the heat of the engine system during the circulation of the engine system, causing the temperature of the oil to continue to rise. When the first temperature detection element 4 detects that the oil temperature at the oil outlet 12 continues to rise, and even exceeds the operating temperature of the engine 400, the controller 6 controls the on-off valve 331 to open, so that the heat exchange medium flows into the heat exchange channel 33, and cooperates with the oil in the oil channel 13 for heat exchange, so that the oil temperature in the oil channel 13 is reduced, reducing the risk of high temperature oil flowing into the engine 400 and causing the engine 400 to be overheated, thereby reducing the risk of engine 400 failure due to excessive operating temperature.

[0062] Furthermore, the on-off valve 331 can control the flow of the heat exchange medium by setting different openings, thereby controlling the heat exchange efficiency between the heat exchange medium and the oil in the oil channel 13, which is conducive to achieving precise control of the oil temperature.

[0063] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the heat exchange medium inlet 31 and the heat exchange medium outlet 32 ​​are located on the same side of the cooling element 3 .

[0064] Among them, by arranging the heat exchange medium inlet 31 and the heat exchange medium outlet 32 ​​on the same side of the cooling part 3, the arrangement of the heat exchange medium inlet 31 and the heat exchange medium outlet 32 ​​can be made reasonable, thereby reducing the flow distance of the heat exchange medium in the cooling part 3, and facilitating the heat exchange medium to quickly flow out of the heat exchange channel 33 after the heat exchange between the heat exchange medium and the oil is completed, so that the low-temperature heat exchange medium enters the heat exchange channel 33 to continue to exchange heat with the oil in the oil channel 13, thereby improving the heat exchange efficiency between the heat exchange medium and the oil in the oil channel 13, which is beneficial to the rapid cooling of the oil in the oil channel 13, and further reducing the risk of failure of the engine 400 due to excessive operating temperature.

[0065] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the cooling member 3 and the heating member 2 are opposite to each other and spaced apart along the extending direction of the oil channel 13 , so as to form an assembly space 14 between the cooling member 3 and the heating member 2 .

[0066] Among them, along the extension direction of the oil channel 13, the cooling part 3 and the heating part 2 are arranged opposite to each other, and the cooling part 3 and the heating part 2 are arranged separately to form an assembly space 14 between the cooling part 3 and the heating part 2, so that other components of the engine system can be assembled in the assembly space 14, reducing the risk of interference between the oil connecting device 100 and other components of the engine system, which is beneficial to the layout of the engine system, reducing the space occupied by the engine system in the vehicle, and further beneficial to the overall layout of the vehicle.

[0067] Furthermore, the cooling element 3 and the heating element 2 are spaced apart so that there is a certain distance between the cooling element 3 and the heating element 2, reducing the risk of mutual interference between the heating element 2 and the cooling element 3, thereby improving the coordination effect between the heating element 2 and the cooling element 3, and further facilitating the effect of precise control of the oil temperature.

[0068] like Figure 3 As shown, the engine system according to the embodiment of the present invention includes: an engine 400, the engine 400 having an oil pump 200 and a main oil gallery 300;

[0069] The oil communication device 100 is the oil communication device 100 of the above embodiment, the oil inlet 11 is connected to the oil pump 200 of the engine 400, and the oil outlet 12 is connected to the main oil channel 300 of the engine 400.

[0070] As some embodiments of the present application, the vehicle may include an oil pan 500, and the oil may be stored in the oil pan 500. When the vehicle is started, the heating element 2 mounted on the device body 1 is powered on to increase the temperature. The oil in the oil pan 500 is pumped from the oil inlet 11 into the oil channel 13 under the action of the oil pump 200, so that the heating element 2 exchanges heat with the oil in the oil channel 13. The oil can absorb the heat of the heating element 2 to increase the temperature of the oil. The oil after the temperature is increased flows into the main oil channel 300 through the oil outlet 12, and flows to the inside of the engine 400 through the main oil channel 300, so that the oil after the temperature is increased can play a lubricating role inside the engine 400. After the oil in the engine 400 is lubricated, it falls back to the oil pan 500 under the action of gravity, thereby realizing the circulation of the oil. By arranging the heating element 2 to be sleeved on the device body 1, and the heating element 2 heats the oil in the oil channel 13, the temperature of the oil in the oil channel 13 can be increased, which is beneficial to reduce the viscosity of the oil and improve the fluidity of the oil, thereby reducing the mechanical wear of the components in the engine 400, and further improving the working reliability of the engine 400.

[0071] The vehicle according to the embodiment of the present invention includes the engine system of the above embodiment. By arranging the heating element 2 to be sleeved on the device body 1, and the heating element 2 heating the oil in the oil channel 13, the temperature of the oil in the oil channel 13 can be increased, which is beneficial to reduce the viscosity of the oil and improve the fluidity of the oil, thereby reducing the mechanical wear of the parts in the engine 400, which is beneficial to improve the working reliability of the engine system, and further prolonging the service life of the vehicle.
