[0003] In the split oil cooler and oil filter, the oil cooler and oil filter are two different assembly parts and are installed on the engine-related main oil channel, which has high requirements on the assembly layout space and poor matching versatility with the entire vehicle; also, when the oil filter or oil cooler fails and cannot be replaced in time, it will cause engine-related failures. Summary of the invention

[0004] The embodiment of the present application provides an oil filter and oil cooler assembly and a vehicle to solve the problem in the related art that when the oil filter or oil cooler fails and cannot be replaced in time, it causes engine-related failures.

[0012] In some embodiments, a positioning structure is provided at one end of the interior of the oil filter housing away from the filter cover, and one end of the filter element is clamped in the oil filter housing through the positioning structure.

[0013] In some embodiments, the oil filter is also provided with a pressure / temperature sensor;

[0014] A control unit is connected between the heating component and the pressure / temperature sensor. The control unit is used to receive data from the pressure / temperature sensor and control the heating component to heat the engine oil.

[0015] In some embodiments, the heating component includes a heating solenoid valve and a heating resistance wire, and the heating solenoid valve is connected to the heating resistance wire.

[0016] In some embodiments, the oil cooler includes a cooler body, and a water inlet pipe and a water return pipe are provided on the cooler body.

[0026] The four oil circuits designed in this way can cope with the situation where the oil filter or oil cooler fails, or both the oil filter and the oil cooler fail at the same time and cannot be replaced in time, without affecting the engine. Therefore, it can solve the problem in the related technology that when the oil filter or the oil cooler fails and cannot be replaced in time, it causes engine-related failures.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] The embodiment of the present application provides an oil filter and oil cooler assembly, which can solve the problem in the related art that when the oil filter or oil cooler fails and cannot be replaced in time, it will cause engine-related failures.

[0038] See also Figures 1 to 5 As shown, the present application provides an oil filter and oil cooler assembly (hereinafter referred to as "assembly"), including an oil filter 1, an oil cooler 2 and a pressure limiting valve 6, wherein:

[0039] The oil filter 1 comprises an oil filter base 11, an oil inlet and an oil outlet are provided on the oil filter base 11, and a first oil circuit, a second oil circuit, a third oil circuit and a fourth oil circuit are connected in parallel between the oil inlet and the oil outlet;

[0040] The oil filter 1 is provided with a heating assembly 3 and a first bypass valve 4. Specifically, the first bypass valve 4 is connected to the second oil circuit, and is used to make the oil flow smoothly through the assembly as the second oil circuit when the oil filter 1 is blocked, so as to complete the cooling of the oil. When the engine is in a low-temperature environment, the heating assembly 3 heats the oil, so that the temperature of the engine oil quickly reaches a suitable range in the low-temperature environment.

[0041] The oil cooler 2 is arranged on the oil filter base 11 and is connected to the oil filter base 11. A second bypass valve 5 is installed on the oil cooler 2. The second bypass valve 5 is connected to the third oil circuit and is used to serve as the third oil circuit to allow the oil to flow smoothly through the assembly when the oil cooler 2 is blocked, thereby completing the oil filtering work.

[0042] The pressure limiting valve 6 is installed on the oil inlet and connected to the fourth oil circuit. It is used as the fourth oil circuit to allow the oil to flow smoothly through the assembly when the oil filter 1 and the oil cooler 2 are both blocked.

[0043] The embodiment of the present application provides an oil filter and an oil cooler assembly. Since the oil cooler 2 is integrated on the oil filter base 11 of the oil filter 1, compared with the oil cooler 2 and the oil filter 1 being separately arranged on the oil path through which the oil flows, space is greatly saved.

[0044] Under normal circumstances, the engine oil flows into the oil filter 1 through the oil inlet of the filter base 11, and then enters the oil cooler 2 connected to the filter base 11 after being filtered, and then flows out from the oil outlet. This is the first oil circuit;

[0045] When the oil filter 1 is blocked due to excessive impurities and the pressure is too high, the first bypass valve 4 on the oil filter 1 is opened, and the oil directly enters the oil cooler 2 without being filtered, that is, the oil enters the first bypass valve 4 from the oil inlet, then enters the oil cooler 2, and finally flows into the main oil channel of the engine from the oil outlet. This is the second oil circuit, so as to prevent the engine from causing engine-related failures due to low system oil pressure;

[0046] When the oil cooler 2 is blocked by impurities or other reasons, causing the resistance to be too large and reaching the design value of the second bypass valve 5, the second bypass valve 5 is opened, and the oil directly enters the main oil gallery of the engine without being cooled, that is, the oil passes through the oil filter 1 from the oil inlet, and then directly enters the main oil gallery of the engine from the oil outlet through the second bypass valve 5. This is the third oil circuit, which prevents the engine from causing engine-related failures due to low system oil pressure;

[0047] When the oil cooler 2 and the oil filter 1 are blocked at the same time, the oil inlet pressure increases to a safe value, the pressure limiting valve 6 opens, the oil is not filtered and cooled, and directly enters the oil return port through the oil inlet through the pressure limiting valve 6 to prevent the engine from causing related failures due to lack of oil lubrication or too low oil pressure;

[0048] The four oil circuits are designed in this way, which can cope with the situation that when the oil filter 1 or the oil cooler 2 fails, or when the oil filter 1 and the oil cooler 2 fail at the same time and cannot be replaced in time, it will not affect the engine. Therefore, it can solve the problem in the related art that when the oil filter 1 or the oil cooler 2 fails and cannot be replaced in time, it will cause engine-related failures.

[0049] In some optional embodiments, see Figure 1As shown, the oil filter 1 includes an oil filter housing 12 and a filter cover 13, wherein the oil filter housing 12 is connected to the oil filter base 11 and communicates with each other, and the filter cover 13 is detachably connected to the oil filter housing 12 to seal the oil filter housing 12;

[0050] Specifically, an oil filter sealing ring 15 is provided at the connection between the filter cover 13 and the oil filter housing 12 to prevent oil leakage; optionally, the filter cover 13 is threadedly connected to the oil filter housing 12;

[0051] When the filter cover 13 is installed on the oil filter housing 12, an accommodation space is formed between the filter cover 13 and the oil filter housing 12. Preferably, the first bypass valve 4 is arranged in the accommodation space.

[0052] Preferably, the oil filter 1 also includes a filter element 14, which is detachably arranged in the accommodating space formed by the oil filter housing 12 and the filter cover 13. Optionally, the side of the oil filter housing 12 connected to the oil filter base 11 is a conical surface, that is, the filter element 14 can be stuck at different diameters of the conical surface to complete the fixation. Without redesigning the oil filter base, by changing the diameter of the filter element center tube and the filter element height, filter element assemblies with different specifications of dust holding capacity can be adapted, thereby adapting to different maintenance mileage requirements of the whole vehicle / engine.

[0053] Combination Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 They are schematic diagrams of the first oil circuit and the second oil circuit respectively. The arrows indicate the flow path of the engine oil. It can be seen that when the engine oil cooler 2 and the engine oil filter 1 are working normally, the engine oil enters the engine filter housing 12 from the oil inlet, then enters the engine filter base 11 from the filter paper layer of the filter element 14, and then flows from the engine filter base 11 to the engine oil cooler 2, and finally flows into the main oil channel of the engine from the oil outlet;

[0054] A first bypass valve 4 is provided in the oil filter 1. When the pressure difference between the inside and outside of the filter element 14 reaches the design pressure limit of the first bypass valve 4 due to the increase of impurities attached to the oil filter 1, the first bypass valve 4 opens. Figure 3 As shown, the engine oil directly enters the oil cooler 2 without being filtered by the filter element 14 to prevent the engine from causing engine-related failures due to too low system oil pressure. The engine oil circulates and cools in the oil cooler 2 and then enters the oil filter base 11 again. The coolant enters the oil cooler through the water inlet pipe 21 on the oil cooler 2, and after cooling the high-temperature oil, it flows into the engine cooling system through the return water pipe 22.

[0055] In some optional embodiments, a positioning structure is provided at one end of the interior of the oil filter housing 12 away from the filter cover 13, and one end of the filter element 14 is clamped in the oil filter housing 12 through the positioning structure; of course, the filter cover 13 can also limit the filter element 14 together with the positioning structure at the other end, so that the filter element 14 is firmly fixed in the oil filter housing 12.

[0056] In some optional embodiments, the oil inlet on the oil filter base 11 adopts a large flow area design structure to reduce the oil flow resistance.

[0057] In some optional embodiments, see Figure 1 As shown, the oil filter 1 is also provided with a pressure / temperature sensor 7. Specifically, the pressure / temperature sensor 7 is connected to the oil filter base 11, and the sensing end is inserted into the oil passage to sense the oil temperature and display it on the instrument panel;

[0058] Optionally, the heating component 3 includes a heating solenoid valve 31 and a heating resistor 32, and the heating solenoid valve 31 is connected to the heating resistor 32. The heating solenoid valve 31 is used to heat the heating resistor 32 to make the heating resistor 32 generate heat, thereby achieving the purpose of heating the engine oil.

[0059] In some optional embodiments, a pressure / temperature sensor 7 is provided on the oil filter 1. Specifically, a control unit is connected between the heating component 3 and the pressure / temperature sensor 7. The control unit stores oil temperature and oil pressure data. The pressure / temperature sensor 7 transmits the sensed real-time data to the control unit. If it exceeds the data range in the control unit, the control unit controls the heating solenoid valve 31 to make the oil reach a suitable pressure and temperature. That is, when the engine is in a low temperature environment, the control unit controls the heating solenoid valve 31 to control the heating resistor 32 according to the calibration data based on the oil temperature value sensed by the above-mentioned pressure / temperature sensor 7 to heat the oil, so that the engine oil temperature and pressure quickly reach a suitable range in a low temperature environment.

[0060] Specifically, the heating assembly 3, the pressure / temperature sensor 7 and the control unit are integrated into an oil temperature and pressure closed-loop control module, which saves layout space while also improving safety.

[0061] In some optional embodiments, see Figure 1 As shown, the oil cooler 2 includes a cooler body 23 , on which a water inlet pipe 21 and a water return pipe 22 are provided.

[0062] Specifically, the water inlet pipe 21 and the water return pipe 22 are used for the coolant to enter the cooler body 23 and flow out of the cooler body 23. Preferably, the water inlet pipe 21 and the water return pipe 22 are welded to the cooler body 23, with a simple structure and low manufacturing cost. To adapt to the water inlets and outlets of different engine coolants, it is only necessary to change the orientation angle of the welding pipe. If it is necessary to adapt to different oil heat dissipation requirements, it is only necessary to change the thickness of the welding pipe to change the flow rate of the coolant.

[0063] In some optional embodiments, see Figure 1 As shown, Figure 1 An exploded view of the oil filter and oil cooler assembly provided in an embodiment of the present application, wherein the oil filter base 11 has a first mounting surface and a second mounting surface, wherein the first mounting surface is arranged toward the oil cooler 2 for connection with the oil cooler 2, and the second mounting surface is arranged away from the oil cooler 2 for connection with the engine;

[0064] Alternatively, see Figure 1 As shown, a first sealing ring 8 is provided between the first mounting surface and the oil cooler 2. Since the oil filter base 11 is connected to the oil cooler 2, the oil will flow through the joint surface between the two, so the first sealing ring 8 can seal the joint surface here.

[0065] Alternatively, see Figure 1 As shown, the oil cooler 2 also includes a mounting bottom surface, which is a surface of the oil cooler 2 facing the oil filter base 11 and used to be mounted on the oil filter base 11. The mounting bottom surface is connected to the above-mentioned first mounting surface, and a bolt assembly 10 is provided on the mounting bottom surface. Correspondingly, a bolt hole is also provided on the first mounting surface of the oil filter base 11. The oil cooler 2 is fixedly connected to the oil filter base 11 through the bolt assembly 10.

[0066] Optionally, the bolt assembly 10 includes a plurality of bolts, the mounting bottom surface is provided with bolt holes, the first mounting surface is provided with the same number of bolt holes, and the bolt holes on the first mounting surface do not penetrate into the second mounting surface, and the plurality of bolts simultaneously penetrate the mounting bottom surface and the first mounting surface, and the oil cooler 2 is press-fitted into the bolt holes on the first mounting surface, thereby completing the installation of the oil cooler 2;

[0067] Alternatively, the bolt assembly 10 includes a bolt and a nut. The bolt passes through the mounting bottom surface and penetrates the oil filter base 11 to mount the oil cooler 2 on the oil filter base 11, and the nut is sleeved on the bolt and abuts against the second mounting surface.

[0068] Optionally, there are three bolt assemblies 10, which are arranged at intervals on the circumference of the installation bottom surface; the oil cooler 2 is fixed to the oil filter base 11 using the bolt assemblies 10, so that the installation and removal of the oil cooler 2 becomes simple;

[0069] Optionally, the bolts are long enough to pass through the oil filter base 11 and connect to the engine. The oil filter base 11 is also fixed to the engine by bolts. During assembly, the assembly is directly connected and fixed to the engine body with bolts, and there is no need to disassemble the oil cooler for the second time, which improves the assembly cycle and reduces the risk of parts failure caused by secondary disassembly and assembly.

[0070] Alternatively, the oil cooler 2 and the oil filter base 11 are an integrated structure, and the oil filter base 11 is fixed to the engine body by bolts to complete the fixation of the entire assembly.

[0071] Preferably, the oil filter base 11 is mounted on the engine block by another set of bolts, so that when the oil cooler 2 needs to be replaced, the entire assembly does not need to be replaced.

[0072] The present application provides an oil filter and oil cooler assembly, combined with Figure 1 and Figure 4 As shown, the second bypass valve 5 is arranged between the first mounting surface and the mounting bottom surface. When the resistance of the oil cooler 2 is too large due to blockage of impurities or other reasons and reaches the design value of the second bypass valve 5, the second bypass valve 5 is opened, and the oil directly enters the main oil channel of the engine without cooling, that is:

[0073] The engine oil enters the oil filter 1 from the oil inlet, is filtered by the filter element 14, and then enters the filter base 11. It no longer enters the oil cooler 2, but passes through the second bypass valve 5 and directly enters the main oil channel of the engine from the oil outlet on the filter base 11, forming a third oil circuit to prevent the engine from causing engine-related failures due to low system oil pressure.

[0074] Furthermore, combined with Figure 1 As shown, a pressure limiting valve 6 is also provided on the oil filter base 11. When the oil cooler 2 and the oil filter 1 are blocked at the same time, the oil inlet pressure increases to a safe value, the pressure limiting valve 6 opens, and the oil is not filtered or cooled, and directly enters the oil return port through the oil inlet through the pressure limiting valve 6 to prevent the engine from causing related failures due to lack of oil lubrication or too low oil pressure. Of course, this is only a temporary method, and it can be repaired later by replacing the oil cooler 2 and the oil filter 1, or the oil filter and the oil cooler assembly.

[0075] In some optional embodiments, when the oil filter and oil cooler assembly is assembled on a pickup truck, the end of the oil filter housing 12 connected to the filter cover 13 is installed toward the front end of the engine. When the filter element 14 is replaced during vehicle maintenance, the filter cover 13 is first loosened to drain the oil. After the oil is drained, the filter element 14 is pulled out and removed, and a new filter element 14 is replaced to facilitate assembly.

[0076] In some optional embodiments, see Figure 6 As shown, the angle α formed between the length direction of the oil filter 1 (i.e., the length direction of the filter element 14) and the length direction of the oil cooler 2 is less than 180°, so that the assembly can better adapt to the installation space which is not large. It should be noted that the angle α should not be too small, so as not to affect the normal circulation of the oil. The angle range provided in this embodiment is 100° to 180°, and the specific angle can be determined according to the actual vehicle installation space.

[0077] In some optional embodiments, see Figure 7 As shown, when the oil filter and oil cooler assembly is assembled on a pickup truck, the oil filter 1 and the oil cooler 2 are not at the same height in the z direction. Specifically, since one side of the oil filter base 11 needs to be mounted on the engine and the oil cooler 2 requires a certain installation space, the oil cooler 2 is preferably mounted on the first mounting surface of the oil filter base 11;

[0078] See also Figure 7 As shown, in this embodiment, the oil filter housing 12 is arranged on the side of the oil filter base 11, the height of the oil filter housing 12 equipped with the filter element 14 in the z direction is consistent with the height of the oil filter base 11 in the z direction, and the oil cooler 2 is higher than the oil filter base 11 in the z direction, so the height of the oil cooler 2 in the z direction is higher than the height of the oil filter housing 12 equipped with the filter element 14 in the z direction. This arrangement makes the oil filter 1 and the oil cooler 2 at different heights to adapt to the complex installation environment near the pickup engine.

[0079] In some optional embodiments, see Figure 1 As shown, the second mounting surface of the oil filter base 11 that is combined with the engine is also provided with a sealing structure. Specifically, a second sealing ring 9 is provided between the second mounting surface and the engine to seal the combined surface between the two.

[0080] The present application also provides a vehicle, which includes any of the above-mentioned oil filter and oil cooler assemblies, which are arranged on the engine. Specifically, the end of the oil filter housing 12 connected to the filter cover 13 is installed toward the front end of the engine. When the filter element 14 is replaced during vehicle maintenance, the filter cover 13 is first unscrewed to release the oil. After the oil is released, the filter element 14 is pulled out and removed, and a new filter element 14 is replaced, which is convenient for assembly.

[0081] Preferably, the vehicle is a pickup truck.

[0082] The present application provides an oil filter and oil cooler assembly and a vehicle, which have the following advantages:

[0083] 1. The present invention provides an oil filter and oil cooler assembly, which integrates a split oil cooler 2 and an oil filter 1. Compared with an oil cooler with a filter assembly arranged at the same height, the present invention has a stronger adaptability and is particularly suitable for pickup truck engines. The filter cover 13 is tilted downward toward the front end of the engine, providing the vehicle with sufficient maintenance space for replacing the filter element. The oil is filtered before being cooled, which prevents impurities in the oil from being deposited in the oil cooler 2, thereby increasing the service life of the oil cooler 2. Compared with the split oil cooler 2 and the oil filter 1, the present invention has a more compact structure, low cost, short assembly cycle, and higher economic benefits. On the other hand, compared with the split oil filter 1 and the oil cooler 2 being two different parts, the oil flow channel is longer than the integrated type, and the flow resistance is larger, the flow resistance is effectively reduced.

[0084] 2. The present invention provides an oil filter and oil cooler assembly, wherein the oil inlet of the oil filter base 11 adopts a large flow area design structure, which reduces the resistance of the oil flow channel, makes the oil side pressure difference of the assembly smaller, and provides a higher oil pressure to the main oil channel of the engine, thereby ensuring the pressure requirements of the engine lubrication system and providing space for reducing the cost of the oil pump;

[0085] 3. The present invention provides an oil filter and oil cooler assembly, wherein a pressure / temperature sensor 7 is provided on the oil filter base 11, which has stronger functionality and can detect the pressure and temperature of the oil during the operation of the engine in real time, thereby ensuring that the engine operates in a safe oil lubrication environment;

[0086] 4. The present invention provides an oil filter and oil cooler assembly, which is provided with a heating component 3, a pressure / temperature sensor 7 and a control unit, and is integrated into an oil temperature and pressure closed-loop control module. When the engine is in a low-temperature environment, the control unit controls the heating solenoid valve 31 to control the heating resistor 32 to be energized according to the calibration data through the oil temperature value input by the pressure / temperature sensor 7, so as to heat the oil. The engine oil temperature and pressure quickly reach a suitable range in a low-temperature environment, so as to reduce the engine starting power consumption and abnormal wear of each friction pair;

[0087] 5. The present invention provides an oil filter and oil cooler assembly, which is provided with a first bypass valve 4, a second bypass valve 5 and a pressure limiting valve 6, so as to prevent the engine from causing related failures due to lack of oil lubrication or too low oil pressure when the oil cooler 2 and the oil filter 1 are blocked;

[0088] 6. The present invention provides an oil filter and oil cooler assembly, wherein the oil filter base 11 adopts a conical surface sealing design structure, that is, the filter element 14 can be stuck at different diameters of the conical surface to complete the fixation. Without the need to redesign the oil filter base, the filter element 14 center tube diameter and the height of the filter element 14 can be changed to adapt to filter element assemblies with different dust holding capacities, thereby adapting to different maintenance mileage requirements of the vehicle / engine;

[0089] 7. The present invention provides an oil filter and oil cooler assembly, which has a simple installation and disassembly method. During assembly, the assembly is directly connected and fixed to the engine body with a bolt assembly 10, and there is no need to perform secondary disassembly and assembly of the oil cooler 2, thereby improving the assembly cycle and reducing the risk of parts failure caused by secondary disassembly and assembly.
