[0001] This application belongs to the field of engine technology, and more specifically, relates to an online oil monitoring device, an oil cooler assembly, and a vehicle. Background Technology

[0002] Engine oil reduces friction and wear between internal parts, but over time, it deteriorates, losing its effectiveness and failing to lubricate and cool the engine properly, thus severely impacting engine performance and lifespan. Therefore, it is necessary to test the quality of the engine oil.

[0003] In existing technologies, engine oil quality is usually checked by regular manual inspection, but this method is not timely; or sensors are used for detection, but the installation position of the sensors can easily affect the quality and stability of the engine-cooled cylinder block, and they are also easily interfered with by internal engine components. Utility Model Content

[0004] The purpose of this application is to provide an online oil monitoring device, an oil cooler assembly, and a vehicle, aiming to solve the technical problems of poor effectiveness, impact on the quality of the engine-cooled cylinder block, and susceptibility to interference from other structural components in existing engine oil monitoring methods.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, an online oil monitoring device is provided, comprising an engine-cooled cylinder block and an engine-cooled cap spaced apart along a first direction; the engine-cooled cylinder block is provided with a cooling water passage and a lubricating oil passage, and the engine-cooled cap is provided with a cooling circuit and a lubrication circuit; the online oil monitoring device further includes: The connecting fixture has a first contact surface and a second contact surface arranged opposite to each other along the first direction; the first contact surface is pressed against and fixed to the engine cooler cylinder block, and covers the connecting end of the cooling water circuit and the connecting end of the lubricating oil circuit; the second contact surface is pressed against and fixed to the engine cooler cover, and covers the connecting end of the cooling circuit and the connecting end of the lubrication circuit; the connecting fixture is provided with a clearance water circuit and a clearance oil circuit that are both arranged through the first direction. The measuring sensor is fixed on the connecting fixture; In the first direction, the cooling water path is connected to the cooling circuit through the clearance water path; the lubricating oil path is connected to the lubrication circuit through the clearance oil path; and the sensing end of the measuring sensor extends into the clearance oil path.

[0006] Compared with the prior art, the solution shown in this application embodiment can facilitate the installation of the measuring sensor by setting a separate connecting tool between the engine-cooled cylinder block and the engine-cooled cover, thus avoiding the impact of the separate hole structure set for installing the measuring sensor on the quality of the engine cylinder block or engine-cooled cover. Meanwhile, the measurement sensor is installed in an independently set connecting fixture, which can avoid interference between the measurement sensor and the internal structure of the engine cooling cylinder block or engine cooling cover, ensuring the accuracy of measurement and the convenience of installation. Furthermore, the connecting fixture is equipped with a clearance water passage and a clearance oil passage, which can realize the water passage of cooling water between the engine-cooled cylinder block and the engine-cooled cover, as well as the oil passage of lubricating oil, to ensure the normal operation of the engine-cooled cylinder block; the sensing end of the measuring sensor extends into the clearance oil passage, which can realize real-time monitoring of the engine oil in the clearance oil passage, which is conducive to real-time monitoring of the quality of lubricating oil, timely warning of engine oil deterioration, and can optimize engine operating efficiency and extend engine life; In addition, the thickness of the connecting fixture in the first direction can be set according to actual needs, which can meet the installation needs of measuring sensors of different sizes. Compared with the sensor structure set on the machine cooler cover in the traditional technology, the design of the connecting fixture in this application is more flexible. Therefore, the online oil monitoring device provided in this application can monitor the quality of lubricating oil in real time, avoid the impact of the installation of the measuring sensor on the quality of the engine-cooled cylinder block, and avoid interference from other structural components during the installation process.

[0007] In conjunction with the first aspect, in one possible implementation, the connecting fixture includes: A connecting seat has a first contact surface and a second contact surface; the connecting seat is provided with the clearance water passage and the clearance oil passage; Mounting base, fixed on the connecting base; the mounting base is provided with a connecting hole communicating with the clearance oil passage; The measuring sensor is fixed inside the connecting hole, and the sensing end of the measuring sensor extends from the connecting hole into the clearance oil circuit.

[0008] By setting up a connector, it is easy to arrange clearance water and clearance oil passages on the connector. By setting up a mounting base, it is easy to install the measuring sensor. Furthermore, the mounting base is provided with a connection hole, through which the measuring sensor can be installed, and the measuring sensor can be easily inserted into the clearance oil passage through the connection hole to monitor the lubricating oil.

[0009] In some embodiments, the connecting seat is placed between the cooler cylinder body and the cooler cover, the mounting seat extends outward between the cooler cylinder body and the cooler cover, and the extended end of the mounting seat is a planar structure suitable for mounting the measuring sensor.

[0010] The measuring sensor extends outward between the engine cooler cylinder block and the engine cooler cover, which avoids interference between the measuring sensor and the external structure of the engine cooler cylinder block or engine cooler cover, and improves the convenience of measuring sensor installation.

[0011] For example, the connecting hole extends perpendicular to the first direction, and one end of the connecting hole penetrates the planar structure, while the other end is connected to the clearance oil passage.

[0012] By extending the connection hole along the first direction, the connection hole can be made to pass through in a direction perpendicular to the plane structure and connect with the corresponding clearance oil circuit, which helps to ensure the stability of the measurement sensor installation.

[0013] For example, the connecting seat and the mounting seat are an integral structure.

[0014] By designing the connector and mounting base as an integrated structure, it is easier to process and produce, and saves on the corresponding assembly process, which helps to improve installation efficiency.

[0015] In conjunction with the first aspect, in one possible implementation, the connecting fixture is provided with a plurality of mounting holes, which are spaced apart along the circumference of the connecting fixture at the outer edges of the clearance water passage and the clearance oil passage; each mounting hole corresponds to a set of connecting bolts; The connecting bolts are used to pass through the cooler cover and the mounting hole in sequence and are fixed on the cooler cylinder body so that the first mating surface is tightly attached to and fixed on the cooler cylinder body, and the second mating surface is tightly attached to and fixed on the cooler cover.

[0016] Multiple mounting holes are provided to enable multi-point connections between the connecting fixture and the engine-cooled cylinder block and engine-cooled cover. By placing the connecting holes on the outer circumferential edge of the connecting fixture, it is convenient to facilitate the flow of cooling water and lubricating oil in the middle of the connecting fixture, which helps to improve the compatibility between the connecting fixture and the engine-cooled cylinder block and engine-cooled cover. The connecting bolts are used to fix the engine-cooled cylinder block, engine-cooled cover, and connecting fixture together.

[0017] In conjunction with the first aspect, in one possible implementation, the yielding water passage includes an inlet channel and an outlet channel that pass through the connecting fixture along the first direction; the yielding oil passage includes an inlet channel and an outlet channel that pass through the connecting fixture along the first direction.

[0018] By setting up inlet and outlet channels, this application facilitates the separate conduction of cooling water inlet and outlet paths, thereby achieving cooling water circulation; similarly, by setting up inlet and outlet channels, it facilitates the separate conduction of lubricating oil inlet and outlet paths, thereby achieving lubricating oil circulation.

[0019] In some embodiments, a first sealing ring is provided at each of the two through ends of the water inlet channel, a second sealing ring is provided at each of the two through ends of the water outlet channel, a third sealing ring is provided at each of the two through ends of the oil inlet channel, and a fourth sealing ring is provided at each of the two through ends of the oil outlet channel.

[0020] By setting the first, second, third, and fourth sealing rings respectively, it is beneficial to achieve the sealing of the connection end between the water circuit and the oil circuit, thus avoiding water and oil leakage problems.

[0021] For example, the water inlet channel is located close to the oil inlet channel; the first sealing ring and the third sealing ring are connected by a first connecting portion; The water outlet channel is located close to the oil outlet channel; the second sealing ring and the fourth sealing ring are connected by a second connecting part.

[0022] By bringing the water inlet channel and oil inlet channel closer together, and the water outlet channel and oil outlet channel closer together, it is beneficial to form a closer flow path between the internal cooling water and lubricating oil, thereby ensuring the cooling effect of the lubricating oil.

[0023] In addition, by bringing the water inlet channel and the oil inlet channel close to each other, the integrated structural design of the first and third sealing rings can be achieved, which is conducive to the synchronous positioning of the first and third sealing rings and facilitates the installation and positioning efficiency of the first and third sealing rings; similarly, the installation and positioning efficiency of the second and fourth sealing rings can be improved.

[0024] Secondly, embodiments of this application also provide an oil cooler assembly, which includes the aforementioned online oil monitoring device.

[0025] The oil cooler assembly provided in this application, because it includes the aforementioned online oil monitoring device, has all the beneficial effects of the aforementioned online oil monitoring device. It can monitor the quality of lubricating oil in real time, avoid the impact of the installation of the measuring sensor on the quality of the engine-cooled cylinder block, and avoid interference from other structural components during the installation process. This is beneficial for optimizing engine operating efficiency and extending engine life.

[0026] Thirdly, embodiments of this application also provide a vehicle that includes the aforementioned oil cooler assembly.

[0027] The vehicle provided in this application, having included the aforementioned oil cooler assembly, possesses all the beneficial effects of the aforementioned oil cooler assembly, enabling real-time monitoring of lubricating oil quality, minimizing interference during installation, and thus optimizing engine operating efficiency and extending engine life.

[0031] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0032] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] It should be noted that, in this embodiment, the first direction refers to the spacing direction between the engine-cooled cylinder block 7 and the engine-cooled cover 8. For ease of understanding, this application uses the term "attached". Figure 1 The direction indicated by the middle arrow A is used to indicate the first direction.

[0035] In addition, the first direction can also be understood as the thickness direction of the connecting fixture 1; since the connecting fixture 1 is actually a plate-shaped structure, the thickness direction of the connecting fixture 1 is the thickness direction of the plate-shaped structure.

[0036] It is important to understand that changing the engine oil too early prevents it from fully realizing its potential, resulting in a waste of resources and increased waste fluid disposal. On the other hand, changing the engine oil too late increases the risk of abnormal wear between engine components, further increasing engine maintenance costs.

[0037] In traditional technology, the method of manually and periodically testing the quality of lubricating oil is not timely. If the oil deteriorates during the test, then it is the best time to change the oil. However, if the oil deteriorates between two tests, the problem cannot be detected during the earlier test, and damage to internal structural components may have already occurred during the later test. Therefore, it is not conducive to early warning of oil deterioration.

[0038] When installing the measuring sensor 2 to monitor the quality of engine oil, the installation location of the measuring sensor 2 and the ease of installation will affect the installation and monitoring results.

[0039] It should be noted that the measuring sensor 2 used to monitor engine oil quality typically employs a tuning fork resonator, and its measurement and monitoring principle is existing technology. Furthermore, it should be noted that the sensor installation should ensure that air, moisture, particles, etc., do not accumulate around the sensing element. When installed in a complex engine structure, the sensor is prone to interference with other internal components.

[0040] Please refer to the following: Figures 1 to 3The following description will be provided regarding the online oil monitoring device, oil cooler assembly, and vehicle provided in this application. The online oil monitoring device includes a cooler cylinder block 7 and a cooler cap 8 spaced apart along a first direction. The cooler cylinder block 7 has a cooling water passage and a lubricating oil passage, and the cooler cap 8 has a cooling circuit and a lubrication circuit. The online oil monitoring device also includes a connecting fixture 1 and a measuring sensor 2. The connecting fixture 1 has a first contact surface 13 and a second contact surface 14 arranged opposite to each other. The first contact surface 13 is tightly fitted and fixed to the cooler cylinder block 7, covering the connecting ends of the cooling water passage and the lubricating oil passage. The second contact surface 14 is tightly fitted and fixed to the cooler cap 8, covering the connecting ends of the cooling circuit and the lubrication circuit. The connecting fixture 1 has a clearance water passage and a clearance oil passage, both extending through the first direction. The measuring sensor 2 is fixed to the connecting fixture 1. In the first direction, the cooling water passage is connected to the cooling circuit via the clearance water passage; the lubricating oil passage is connected to the lubrication circuit via the clearance oil passage; the sensing end of the measuring sensor 2 extends into the clearance oil passage.

[0041] It should be noted that the online oil monitoring device is installed inside the oil cooler assembly, which includes a cooler cylinder block 7 and a cooler cap 8. In the prior art, the cooler cylinder block 7 is directly and fixedly connected to the cooler cap 8, and the cooling water circuit on the cooler cylinder block 7 is connected to the cooling circuit on the cooler cap 8, forming a cooling water circulation path, while the lubrication circuit and lubricating oil circuit are connected, forming a lubricating oil circulation path. In this embodiment, the connecting fixture 1 is specifically installed between the cylinder block and the cooler cap 8 of the oil cooler, and the cooler cylinder block 7 is used to indicate the position of the oil cooler cylinder.

[0042] It should be understood that the thickness of the engine cooler cover 8 is relatively thin, which has a significant impact on the quality of the engine cooler cover 8 during the installation of the measuring sensor 2, and is prone to problems such as leakage of cooling water or lubricating oil; while the internal structure of the engine cooler cylinder block 7 is complex, and the installation of the measuring sensor 2 will cause interference or disturbance between the internal structure and the measuring sensor 2; however, the connecting fixture 1 in this application is relatively independent, and the thickness of the connecting fixture 1 can be selectively set according to actual needs to meet the hole diameter requirements for the installation of the measuring sensor 2, and will not interfere with or cause disturbance to the internal structure installed earlier.

[0043] It should be noted that there is a circulating water passage for cooling water between the engine-cooled cylinder block 7 and the engine-cooled cover 8. In this application, in order to ensure the flow of cooling water between the engine-cooled cylinder block 7 and the engine-cooled cover 8, a clearance water passage is provided. Therefore, the cooling water can flow from the cooling water passage of the engine-cooled cylinder block 7 through the clearance water passage to the cooling circuit of the engine-cooled cover 8, or it can flow from the cooling circuit of the engine-cooled cover 8 through the clearance water passage to the cooling water passage of the engine-cooled cylinder block 7, thereby realizing the connection between the cooling water passage and the cooling circuit.

[0044] In addition, there is a circulating oil passage between the engine-cooled cylinder block 7 and the engine-cooled cover 8, which is suitable for the flow of lubricating oil. Similarly, in order to ensure the flow of lubricating oil between the engine-cooled cylinder block 7 and the engine-cooled cover 8, a clearance oil passage is provided in this application. Therefore, the lubricating oil can flow back and forth between the lubricating oil passage of the engine-cooled cylinder block 7 and the lubricating circuit of the engine-cooled cover 8 through the clearance oil passage, so as to realize the reciprocating conduction of lubricating oil.

[0045] It is important to understand that the measurement by sensor 2 is based on a tuning fork resonator to monitor the quality of the engine oil. The sensing end of sensor 2 extends into the oil passage to monitor the quality of the engine oil within the passage, providing timely warnings when engine oil deterioration occurs.

[0046] Furthermore, in this application, the sensing end of the measuring sensor 2 extends into the clearance oil circuit, and the lubricating oil flows back and forth through the clearance oil circuit. Therefore, the lubricating oil in the clearance oil circuit is constantly flowing, and the sensing end measures the constantly flowing lubricating oil, rather than the oil that may accumulate or gather at inflection points or dead ends. Therefore, the real-time performance and accuracy of the measurement can be guaranteed.

[0047] It is important to understand that cooling water enters the cooling water circuit through the inlet pipe, and flows through the cooling water circuit, the buffer water circuit, and the cooling loop before being discharged through the outlet pipe, so that cooling water is continuously injected and discharged, which can ensure the cooling effect of the lubricating oil in the engine-cooled cylinder block 7.

[0048] Compared with the prior art, the online oil monitoring device provided in this application facilitates the installation of the measuring sensor 2 by setting a separate connecting fixture 1 between the engine-cooled cylinder block 7 and the engine-cooled cover 8. This avoids the impact of the separately set channel structure for installing the measuring sensor 2 on the quality of the engine-cooled cylinder block or engine-cooled cover 8. At the same time, the installation of the measuring sensor 2 on the independently set connecting fixture 1 can avoid interference between the measuring sensor 2 and the internal structure of the engine-cooled cylinder block 7 or engine-cooled cover 8, ensuring the accuracy of measurement and the convenience of installation.

[0049] Furthermore, the connecting fixture 1 is equipped with a clearance water passage and a clearance oil passage, which can realize the water passage of cooling water between the engine-cooled cylinder block 7 and the engine-cooled cover 8, as well as the oil passage of lubricating oil, to ensure the normal operation of the engine-cooled cylinder block 7; the sensing end of the measuring sensor 2 extends into the clearance oil passage, which can realize real-time monitoring of the engine oil in the clearance oil passage, which is conducive to real-time monitoring of the quality of lubricating oil, timely warning of engine oil deterioration, and optimization of engine operating efficiency and extension of engine life.

[0050] In addition, the thickness of the connecting fixture 1 in the first direction can be set according to actual needs, which can meet the installation needs of measuring sensors 2 of different sizes. Compared with the sensor structure set on the machine cooling cover 8 in the traditional technology, the design of the connecting fixture 1 in this application is more flexible.

[0051] Therefore, the online oil monitoring device provided in this application can monitor the quality of lubricating oil in real time, avoid the impact of the installation of the measuring sensor 2 on the quality of the engine-cooled cylinder block 7, and avoid interference from other structural components during the installation process.

[0052] Please see Figure 1 In some possible embodiments, the connecting fixture 1 includes a connecting seat 11 and a mounting seat 12; the connecting seat 11 has a first contact surface 13 and a second contact surface 14; the connecting seat 11 is provided with a clearance water passage and a clearance oil passage; the mounting seat 12 is fixed on the connecting seat 11; the mounting seat 12 is provided with a connecting hole 121 communicating with the clearance oil passage; wherein, the measuring sensor 2 is fixed in the connecting hole 121, and the sensing end of the measuring sensor 2 extends into the clearance oil passage from the connecting hole 121.

[0053] By setting the connecting seat 11, it is convenient to arrange the clearance water passage and clearance oil passage on the connecting seat 11. By setting the mounting seat 12, it is convenient to install the measuring sensor 2. The mounting seat 12 is provided with a connecting hole 121, through which the measuring sensor 2 can be installed, and the measuring sensor 2 can be conveniently inserted into the clearance oil passage from the connecting hole 121 to monitor the lubricating oil.

[0054] The connecting seat 11 is clamped between the engine cooling cylinder block 7 and the engine cooling cover 8, and the connecting seat 11 is fixed to the engine cooling cylinder block 7 and the engine cooling cover 8 respectively to ensure the tightness of the connection between the connecting seat and the engine cooling cylinder block 7 and the engine cooling cover 8.

[0055] The mounting base 12 is fixed to the connecting base 11, which facilitates the insertion of the sensing end of the measuring sensor 2 from the mounting base 12 into the connecting base 11. Specifically, the fixing method between the mounting base 12 and the connecting base 11 can be selectively set according to actual needs.

[0056] The measuring sensor 2 is fixed in the connecting hole 121. Optionally, the measuring sensor 2 is fixed to the mounting base 12 by welding to ensure the connection between the measuring sensor 2 and the mounting base 12 is stable. In this case, the connecting hole 121 can be set as a through hole, and the sensing end of the measuring sensor 2 passes through the connecting hole 121 and extends into the relief oil passage to realize the measurement of the oil in the relief oil passage.

[0057] Optionally, the connection hole 121 is a threaded hole, and the measuring sensor 2 is screwed and fixed in the connection hole 121. After the sensing end of the measuring sensor 2 is screwed into the connection hole 121, it extends into the clearance oil circuit.

[0058] It should be noted that, in the first direction, the thickness of the mounting base 12 is not greater than the thickness of the connecting base 11; optionally, the thickness of the mounting base 12 is equal to the thickness of the connecting base 11; optionally, the thickness of the mounting base 12 is less than the thickness of the connecting base 11.

[0059] Please see Figure 1 In some embodiments, the connecting seat 11 is placed between the engine cooling cylinder body 7 and the engine cooling cover 8, and the mounting seat 12 extends outward between the engine cooling cylinder body 7 and the engine cooling cover 8, and the extended end of the mounting seat 12 is a planar structure suitable for mounting the measuring sensor 2.

[0060] It should be understood that in some scenarios, the diameter of the measuring sensor 2 is larger than the thickness of the connecting fixture 1 in the first direction. If the mounting base 12 is placed between the engine cooling cylinder block 7 and the engine cooling cover 8, the measuring sensor 2 also needs to be clamped between the engine cooling cylinder block 7 and the engine cooling cover 8. Therefore, interference between the measuring sensor 2 and the engine cooling cylinder block 7 or the engine cooling cover 8 is likely to occur.

[0061] In this application, the measuring sensor 2 extends outward between the engine cooling cylinder block 7 and the engine cooling cover 8, which can avoid interference between the measuring sensor 2 and the external structure of the engine cooling cylinder block 7 or the engine cooling cover 8, and improve the ease of installation of the measuring sensor 2.

[0062] In addition, by setting a planar structure at the extended end of the mounting base 12, the tightness of the connection between the mounting end of the measuring sensor 2 and the planar structure can be ensured, and the sealing of the end of the connection hole 121 can be easily achieved, preventing oil from leaking from the connection hole 121 to the outside of the connection fixture 1.

[0063] Please see Figure 2 For example, the connecting hole 121 extends perpendicular to the first direction, and one end of the connecting hole 121 passes through the planar structure, while the other end is connected to the clearance oil passage.

[0064] By extending the connection hole 121 along the first direction, the connection hole 121 can be made to pass through in a direction perpendicular to the plane structure and connect with the corresponding clearance oil passage, which helps to ensure the stability of the installation of the measuring sensor 2.

[0065] It should be understood that, since the connecting fixture 1 is equipped with a clearance water passage and a clearance oil passage, and in order to ensure that the clearance water passage can connect the cooling water passage and the cooling circuit, the flow direction of the cooling water in the clearance water passage is the first direction on the main body; similarly, in order to ensure that the clearance oil passage can connect the lubricating oil passage and the lubrication circuit, the flow direction of the lubricating oil in the clearance oil passage is also the first direction on the main body.

[0066] Therefore, when the connection hole 121 extends perpendicular to the first direction, the insertion direction of the sensing end in the connection hole 121 can be perpendicular to the flow direction of the lubricating oil in the clearance oil circuit, which facilitates the perpendicular connection between the sensing end of the measuring sensor 2 and the flowing lubricating oil, thereby facilitating the monitoring of the oil quality.

[0067] In addition, regarding the machining process, since the connection between the connecting hole 121 and the relief oil passage is also perpendicular to each other, the machining direction of the connecting hole 121 can be easily positioned, avoiding the offset of the axis of the connecting hole 121 during the machining process, which would cause misalignment between the connecting hole 121 and the relief oil passage.

[0068] Please see Figure 1 For example, the connector 11 and the mounting base 12 are an integral structure.

[0069] By designing the connector 11 and the mounting base 12 as an integrated structure, it is convenient to process and produce, and saves the corresponding assembly process, which helps to improve installation efficiency.

[0070] In addition, the connecting seat 11 and the mounting seat 12 are an integral structure, which improves the overall strength and stability of the connecting fixture 1 and ensures the reliable installation of the connecting fixture 1 on the engine.

[0071] For example, the connecting seat 11 and the mounting seat 12 are separate structures, and the mounting seat 12 is fixed to the connecting seat 11 by bolt connection or welding.

[0072] Optionally, when the connecting seat 11 and the mounting seat 12 are separate structures, the connecting seat 11 is provided with a first hole and the mounting seat 12 is provided with a second hole. The measuring sensor 2 is screwed into the second hole and extends into the clearance oil passage from the first hole.

[0073] Optionally, a sealing ring is provided between the connecting seat 11 and the mounting seat 12. The sealing ring is arranged circumferentially along the first hole or the second hole to prevent lubricating oil from leaking from the junction of the mounting seat 12 and the connecting seat 11.

[0074] Please see Figure 1 In some possible embodiments, the connecting fixture 1 is provided with a plurality of mounting holes 115, which are spaced apart along the circumference of the connecting fixture 1 at the outer edge of the water passage and the oil passage; each mounting hole 115 corresponds to a set of connecting bolts; wherein, the connecting bolts are used to pass through the engine cooler cover 8 and the mounting holes 115 in sequence and are fixed on the engine cooler cylinder block 7, so that the first contact surface 13 is tightly attached to and fixed on the engine cooler cylinder block 7, and the second contact surface 14 is tightly attached to and fixed on the engine cooler cover 8.

[0075] In this application, the connecting fixture 1 is provided with multiple mounting holes 115, which are spaced apart along the outer edge of the circumference. They are fixed to the engine-cooled cylinder block 7 and engine-cooled cover 8 by connecting bolts, so that the connecting fixture 1 can be firmly fixed to the engine and ensure the connection of the cooling water circuit and the lubricating oil circuit.

[0076] Specifically, multiple mounting holes 115 are provided to achieve multi-point connection between the connecting fixture 1 and the engine-cooled cylinder block 7 and engine-cooled cover 8; by setting the connecting hole 121 on the circumferential outer edge of the connecting fixture 1, it is convenient to realize the conduction of the cooling water flow path and the lubricating oil flow path in the middle of the connecting fixture 1, which is beneficial to improve the compatibility between the connecting fixture 1 and the engine-cooled cylinder block 7 and engine-cooled cover 8; the connecting bolts are provided to realize the fixation between the engine-cooled cylinder block 7, engine-cooled cover 8 and the connecting fixture 1.

[0077] It should be understood that the connecting bolts pass through the engine cooler cover 8 and the mounting hole 115 in sequence and are fixed on the engine cooler cylinder block 7. The connecting bolts can be fixed to the other end of the engine cylinder block by connecting nuts; or, the connecting bolts can be screwed into the threaded hole of the engine cooler cylinder block 7 to achieve the fixing of the connecting bolts to the engine cooler cylinder block 7.

[0078] For example, the connecting fixture 1 in this application is a rectangular structure with a pentagonal cross-section formed by cutting off one corner, wherein the measuring sensor 2 is installed on the cut side. Optionally, to ensure a tight connection between the cut side and the measuring sensor 2, the size of the cut surface can be appropriately extended to increase the installation size of the planar structure, and the specific extension direction can be selectively set according to actual needs.

[0079] At this time, the oil inlet channel 113 and the oil outlet channel 114 are located at two opposite apex corners of the cuboid, with the oil inlet channel 113 close to the cutting side or the oil outlet channel 114 close to the cutting side, so as to realize the connection between the measuring sensor 2 and the oil inlet channel 113 or the oil outlet channel 114.

[0080] Optionally, in this application, the connecting tooling 1 can be cast to achieve an integrated structure design of the connecting seat 11 and the mounting seat 12, and the bracket can be cast to form a pentagonal structure as described above.

[0081] Specifically, the processing method of the connecting tool 1 can be selectively set according to actual needs.

[0082] Please see Figure 1 In some possible embodiments, the water passage includes an inlet channel 111 and an outlet channel 112 that pass through and connect the tooling 1 in a first direction; the oil passage includes an inlet channel 113 and an outlet channel 114 that pass through and connect the tooling 1 in a first direction.

[0083] In this application, by setting up the water inlet channel 111 and the water outlet channel 112, it is beneficial to realize the separate conduction of the cooling water inlet and outlet paths, thereby realizing the circulation of cooling water; similarly, by setting up the oil inlet channel 113 and the oil outlet channel 114, it is beneficial to realize the separate conduction of the lubricating oil inlet and outlet paths, thereby realizing the circulation of lubricating oil; therefore, the setting of the water inlet channel 111 and the water outlet channel 112, as well as the oil inlet channel 113 and the oil outlet channel 114, ensures the normal operation of the cooling and lubrication system.

[0084] Specifically, when the cooling water flows through the engine-cooled cylinder block 7, the connecting fixture 1, and the engine-cooled cover 8, the cooling water enters the inlet channel 111 from the cooling water passage, then flows into the cooling circuit of the engine-cooled cover 8, and flows back to the cooling water passage through the outlet channel 112.

[0085] It should be understood that cooling water circuits and cooling loops are also divided into inlet and outlet paths, and lubrication oil circuits and lubrication loops are also divided into inlet and outlet paths. This part is existing technology and will not be elaborated here.

[0086] Optionally, the cross-sectional shape of the water inlet channel 111, water outlet channel 112, oil inlet channel 113, and oil outlet channel 114 along the direction perpendicular to the first direction can be reasonably designed according to the shape of the corresponding water and oil connection ports on the connecting side.

[0087] Specifically, the sensing end of the measuring sensor 2 extends into the oil inlet channel 113 to contact the oil in the oil inlet channel 113 and monitor its status; optionally, the sensing end of the measuring sensor 2 extends into the oil outlet channel 114 to contact the oil in the oil outlet channel 114 and monitor its status.

[0088] Please see Figure 1 In some embodiments, the two ends of the water inlet channel 111 are respectively provided with a first sealing ring 3, the two ends of the water outlet channel 112 are respectively provided with a second sealing ring 4, the two ends of the oil inlet channel 113 are respectively provided with a third sealing ring 5, and the two ends of the oil outlet channel 114 are respectively provided with a fourth sealing ring 6.

[0089] By setting the first sealing ring 3, the second sealing ring 4, the third sealing ring 5 and the fourth sealing ring 6 respectively, it is beneficial to achieve the sealing of the water passage and the oil passage connection end, avoid water leakage and oil leakage problems, and ensure the sealing of the cooling water flow path and the lubricating oil flow path at both ends of the connecting fixture 1.

[0090] Optionally, the first sealing ring 3, the second sealing ring 4, the third sealing ring 5, and the fourth sealing ring 6 are designed as separate structures. When installing the first sealing ring 3, the second sealing ring 4, the third sealing ring 5, and the fourth sealing ring 6, each sealing ring needs to be positioned sequentially.

[0091] Please see Figure 1 For example, the water inlet channel 111 is located near the oil inlet channel 113; the first sealing ring 3 and the third sealing ring 5 are connected by a first connecting part; the water outlet channel 112 is located near the oil outlet channel 114; and the second sealing ring 4 and the fourth sealing ring 6 are connected by a second connecting part.

[0092] By bringing the water inlet channel 111 and the oil inlet channel 113 closer together, and the water outlet channel 112 and the oil outlet channel 114 closer together, it is beneficial to form a closer connection between the internal cooling water flow path and the lubricating oil flow path, thereby ensuring the cooling effect of the lubricating oil.

[0093] In addition, it should be understood that sequentially positioning each sealing ring increases the positioning and installation time, which is not conducive to improving assembly efficiency. By connecting the first sealing ring 3 and the third sealing ring 5 through the first connecting part, the positioning of the first sealing ring 3 and the third sealing ring 5 can be achieved simultaneously. Similarly, by connecting the second sealing ring 4 and the fourth sealing ring 6 through the second connecting part, the positioning of the second sealing ring 4 and the fourth sealing ring 6 can be achieved simultaneously, which is beneficial to improving the positioning and assembly efficiency of the sealing rings.

[0094] Specifically, the first connecting part is a sealing section connected between the first sealing ring 3 and the third sealing ring 5; similarly, the second connecting part is a sealing section connected between the second sealing ring 4 and the fourth sealing ring 6, and the number of sealing sections can be selectively set according to actual needs. The material of the selected sealing section is the same as that of the above four sets of sealing rings.

[0095] It's important to understand that before monitoring engine oil status using sensor 2, a lubricating oil early warning model needs to be established. Since the rate of engine oil aging is strongly correlated with engine operating conditions and running time, it's necessary to run the engine for 40 hours at different engine speeds, collecting engine oil data at each time point. This test data should then be compared and analyzed with the sensor data for correction. Subsequently, intelligent data analysis methods should be used to identify trends in engine oil status and provide early warnings of potential deterioration. Simultaneously, the engine oil monitoring data should be integrated into the vehicle's central control system. Optionally, a visual interface can be developed to allow drivers and maintenance personnel to view the engine oil status in real time, improving decision-making efficiency.

[0096] Specifically, different operating speeds can be selected: engine idle speed, 1200r / min, 1500r / min, 2000r / min, 2500r / min, 3000r / min, 3500r / min, and 4000r / min.

[0097] It should be understood that the establishment method and principle of the above-mentioned lubricating oil early warning model, as well as the specific connection and structural relationship, are all existing technologies and will not be elaborated here.

[0098] Based on the same inventive concept, this application also provides an oil cooler assembly, which includes the above-mentioned online oil monitoring device.

[0099] It should be noted that the oil cooler assembly in this application also includes an engine cooling cylinder block 7 and an engine cooling cover 8. The connecting bolts pass through the engine cooling cover 8 and the connecting fixture 1 in sequence and are fixed to the engine cooling cylinder block 7. The engine cooling cylinder block 7 is provided with a first mounting surface that mates with the first contact surface 13. The connecting end of the cooling water circuit and the connecting end of the lubricating oil circuit pass through the first mounting surface. The engine cooling cover 8 is provided with a second mounting surface that mates with the second contact surface 14. The connecting end of the cooling circuit and the lubrication circuit pass through the second mounting surface, so that the cooling water circuit, the clearance water circuit and the cooling circuit are connected in the first direction, and the lubricating oil circuit, the clearance oil circuit and the lubrication circuit are connected in the first direction.

[0100] It is important to understand that in traditional technology, the engine-cooled cylinder block 7 and the engine-cooled cover 8 are directly connected, and the cooling water circuit on the engine-cooled cylinder block 7 and the cooling circuit on the engine-cooled cover 8 are directly connected, as are the lubricating oil circuit on the engine-cooled cylinder block 7 and the lubrication circuit on the engine-cooled cover 8.

[0101] In this application, the connecting fixture 1 is disposed between the engine cooling cylinder block 7 and the engine cooling cover 8, and the cooling water circuit, the clearance water circuit and the cooling circuit are connected in the first direction, and the lubricating oil circuit, the clearance oil circuit and the lubrication circuit are connected in the first direction.

[0102] The oil cooler assembly provided in this application, because it includes the above-mentioned online oil monitoring device, has all the beneficial effects of the above-mentioned online oil monitoring device. It can monitor the quality of lubricating oil in real time, avoid the impact of the installation of the measuring sensor 2 on the quality of the engine-cooled cylinder block 7, and avoid interference from other structural components during the installation process. This is conducive to optimizing engine operating efficiency and extending engine life.

[0103] Based on the same inventive concept, this application also provides a vehicle that includes the above-described oil cooler assembly.

[0104] The vehicle provided in this application, having included the aforementioned oil cooler assembly, possesses all the beneficial effects of the aforementioned oil cooler assembly, enabling real-time monitoring of lubricating oil quality, minimizing interference from other structural components, thus optimizing engine operating efficiency and extending engine life.

[0105] In addition, real-time monitoring of engine oil status can improve engine operating safety and overall vehicle performance, providing a guarantee for the safe operation of the vehicle.

[0106] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
