[0037] With the development of automobile technology, especially the continuous progress of electric vehicles and high-performance internal combustion engines, the requirements for oil cooling and filtering of automobile power assemblies are increasing.
[0038] The traditional oil cooling system, oil filtering system and oil pump are usually independent components, and in particular, the oil cooling system and the oil filtering system are arranged in different spaces of the automobile respectively, which is space-wasting and not reasonable in space utilization.
[0039] The utility model provides an integrated oil pan 100. Please refer to Figure 1 And Figure 2 In an embodiment of the utility model, the integrated oil pan 100 provided by the utility model comprises:
[0040] The oil storage shell 10 has an inner cavity 11, the filter mechanism 30 and the oil cooler 40 are integrated in the inner cavity 11, and the oil cooler 40 is configured to exchange heat between the cooling medium in the oil cooler 40 and the oil in the inner cavity 11.
[0041] The oil pump 20 is arranged in the oil storage shell 10 or adjacent to the oil storage shell, and the oil pump 20 is provided with an oil inlet port and an oil outlet port, and the oil inlet port and the oil outlet port are arranged in the inner cavity 11.
[0042] The filter mechanism 30 is located between the oil inlet port and the oil cooler 40, and / or the filter mechanism 30 is located between the oil outlet port and the oil cooler 40. Further, the filter mechanism 30 comprises a first filter part 31 arranged between the oil inlet port and the oil cooler, and the first filter part 31 is in communication with the oil inlet port, and / or the filter mechanism comprises a second filter part 32 arranged between the oil outlet port and the oil cooler 40, and the second filter part 32 is in communication with the oil outlet port.
[0043] In an embodiment, the inner cavity 11 of the oil storage shell 10 is integrated with the filter mechanism 30 and the oil cooler 40, so that the oil in the inner cavity 11 can enter the filter mechanism 30, and the filter mechanism 30 can filter the oil in the inner cavity 11; the oil cooler 40 is configured to exchange heat between the cooling medium in the oil cooler 40 and the oil in the inner cavity 11, so as to cool the oil in the inner cavity 11.
[0044] Optionally, the oil cooler 40 can be a plate heat exchanger or a tube-in-tube heat exchanger. In an embodiment, the oil cooler 40 is arranged in the inner cavity 11. The oil cooler 40 is an immersion oil cooler, which can be immersed in oil, so as to exchange heat between the cooling medium in the oil cooler 40 and the oil filtered by the filter mechanism 30, so as to reduce the temperature of the oil in the inner cavity 11.
[0045] Further, the inner cavity 11 of the oil storage shell 10 stores oil. In order to reduce the oil dirt outside the oil pump 20, the oil pump 20 is arranged outside the oil storage shell 10, the filtering mechanism 30 and the oil cooler 40 are arranged in the inner cavity 11, and then the oil inlet port and the oil outlet port of the oil pump 20 are arranged in the inner cavity 11. The oil inlet port of the oil pump 20 is communicated with the first filtering part 31 of the filtering mechanism 30, and the oil outlet port of the oil pump 20 is communicated with the second filtering part 32 of the filtering mechanism 30, so that the oil pump 20 can not be affected by the oil in the inner cavity 11, and the oil dirt outside the oil pump 20 is avoided. Since the oil pump 20 is arranged outside the oil storage shell 10, the oil inlet port of the oil pump 20 is communicated with the inner cavity 11 of the oil storage shell 10, the filtering mechanism 30 and the oil cooler 40 are integrated in the inner cavity 11 of the oil storage shell 10. The oil flows in the inner cavity 11, is filtered by the filtering mechanism 30 in the inner cavity 11 and is cooled by the oil cooler 40, so that the oil in the inner cavity 11 is cooled. It can be understood that the filtering mechanism 30, the oil cooler 40 and the oil pump 20 are integrated in or beside the oil storage shell 10, which effectively shortens the flow path of the oil, reduces the use of long pipes to connect the filtering mechanism 30, the oil cooler 40 and the oil pump 20 together, and further reduces the friction loss of the oil in the long pipes, thereby improving the flow efficiency of the oil in the oil pump 20, the filtering mechanism 30 and the inner cavity 11. The impurities of the oil filtered by the filtering mechanism 30 are reduced, and the flow efficiency of the oil in the inner cavity 11 is improved.
[0046] Optionally, the filtering mechanism 30 can be integrated or split. If the filtering mechanism 30 is integrated, a part of the structure of the integrated filtering mechanism 30 is arranged between the oil inlet port and the oil cooler 40, and another part of the structure of the integrated filtering mechanism 30 is arranged between the oil outlet port and the oil cooler 40. In this way, the part of the structure and the other part of the structure of the integrated filtering mechanism 30 are arranged in different spaces in the inner cavity 11 to reasonably utilize the space of the inner cavity 11. If the filtering mechanism 30 is split, the part of the structure and the other part of the structure of the filtering mechanism 30 can be arranged separately. The part of the structure of the filtering mechanism 30 can be mounted between the oil inlet port of the oil pump 20 and the oil cooler 40, and the other part of the structure of the filtering mechanism 30 can be mounted between the oil outlet port of the oil pump 20 and the oil cooler 40 to reasonably utilize the space of the inner cavity 11. The oil inlet port and the oil outlet port of the oil pump 20 can be arranged vertically, and the part of the structure and the other part of the structure of the filtering mechanism 30 can also be arranged vertically in the inner cavity 11.
[0047] In this filter mechanism 30, one part of the structure and another part of the structure can be configured as the same filter device. Specifically, one part of the structure and another part of the structure of the filter mechanism 30 can both be two filter devices equipped with filter elements; or one part of the structure and another part of the structure of the filter mechanism 30 can also be two filter devices equipped with filter screens.
[0048] One part of the filter mechanism 30 and another part of the filter mechanism 30 can also be configured as two different filter devices. Specifically, one part of the filter mechanism 30 can be a filter device with a filter screen installed, and the other part of the filter mechanism 30 can be a filter device with filter paper installed.
[0049] The technical solution of this utility model adopts an internal cavity 11 in the oil reservoir 10, in which the filter mechanism 30 and oil cooler 40 are integrated. Furthermore, part of the filter mechanism 30 is positioned between the oil inlet port and the oil cooler 40, and another part is positioned between the oil outlet port and the oil cooler 40, thus making reasonable use of the space in the oil reservoir 10. Moreover, the filter mechanism 30, oil cooler 40, and oil pump 20 are all integrated within or beside the oil reservoir 10, resulting in a high degree of integration and reducing the space occupied inside the integrated oil pan. This, in turn, reduces the volume of the powertrain housing, thus reducing the space occupied by the powertrain housing within the vehicle's interior.
[0050] Please refer to Figure 2 The filtration mechanism 30 includes a first filtration section 31, which is located between the oil inlet port and the oil cooler 40 and is connected to the oil inlet port; the filtration mechanism 30 also includes a second filtration section 32, which is located between the oil outlet port and the oil cooler 40 and is connected to the oil outlet port.
[0051] The first filter section 31 of the filter mechanism 30 is located between the oil inlet port and the oil cooler 40, and the second filter section 32 of the filter mechanism 30 is located between the oil outlet port and the oil cooler 40, so as to make reasonable use of the space of the inner cavity 11 and reduce the need to use long pipes to connect the oil pump 20 and the filter mechanism 30.
[0052] Specifically, if the filtering mechanism 30 is integrated, the first filtering part 31 of the integrated filtering mechanism 30 is arranged between the oil inlet port and the oil cooler 40, and the interface of the first filtering part 31 is arranged corresponding to the oil inlet port of the oil pump 20, so as to connect the interface of the first filtering part 31 with the oil inlet port, shorten the path of the oil flowing from the first filtering part 31 to the oil inlet port of the oil pump 20, and further reduce the use of long pipelines to connect the oil pump 20 with the first filtering part 31 of the filtering mechanism 30. The second filtering part 32 of the integrated filtering mechanism 30 is arranged between the oil outlet port and the oil cooler 40, and the interface of the second filtering part 32 is arranged corresponding to the oil outlet port of the oil pump 20, so as to connect the interface of the second filtering part 32 with the oil outlet port, shorten the path of the oil flowing from the oil outlet port of the oil pump 20 to the second filtering part 32, and further reduce the use of long pipelines to connect the oil pump 20 with the second filtering part 32 of the filtering mechanism 30. Moreover, the first filtering part 31 and the second filtering part 32 of the integrated filtering mechanism 30 are arranged in different spaces of the inner cavity 11, and the space of the inner cavity 11 is reasonably utilized.
[0053] If the filtering mechanism 30 is split, the first filtering part 31 and the second filtering part 32 of the filtering mechanism 30 can be arranged separately. The first filtering part 31 can be arranged in the inner cavity 11 and located between the oil inlet port of the oil pump 20 and the oil cooler 40, and then connected with the oil inlet port. The second filtering part 32 is arranged in the inner cavity 11 and located between the oil outlet port of the oil pump 20 and the oil cooler 40, and then connected with the oil outlet port. The oil inlet port and the oil outlet port of the oil pump 20 can be arranged vertically, so that the first filtering part 31 and the second filtering part 32 of the filtering mechanism 30 are arranged vertically in the inner cavity 11, not only the space of the inner cavity 11 is reasonably utilized, but also the use of long pipelines to connect the oil pump 20 with the filtering mechanism 30 is reduced.
[0054] Optionally, the first filtering part 31 and the second filtering part 32 of the filtering mechanism 30 can be arranged as the same filtering device. Specifically, the first filtering part 31 and the second filtering part 32 can be two filtering devices provided with filter cores, or two filtering devices provided with filter screens. The first filtering part 31 and the second filtering part 32 of the filtering mechanism 30 can also be arranged as two different filtering devices. Specifically, the first filtering part 31 can be a filtering device provided with a filter screen, and the second filtering part 32 can be a filtering device provided with a plurality of filter paper structures.
[0055] The traditional oil filtering system is arranged outside the oil pan, and pipelines are needed to connect the oil filtering system and the oil pan. The oil has friction loss in the pipelines, which reduces the flow efficiency of the oil between the oil filtering system and the oil pan.
[0056] To this end, the inner cavity 11 includes a first accommodating cavity 12, the first accommodating cavity 12 is located between the oil inlet port and the oil cooler 40, the first accommodating cavity 12 is communicated with the oil inlet port, and the oil in the first accommodating cavity 12 can directly flow into the oil inlet port; the first filtering part 31 is arranged in the first accommodating cavity 12, and the first filtering part 31 is configured to filter the oil in the first accommodating cavity 12.
[0057] The first filtering part 31 of the filtering mechanism 30 is arranged in the first accommodating cavity 12 of the oil storage shell 10, the space of the oil storage shell 10 is reasonably utilized, the oil filtered by the first filtering part 31 can directly flow into the oil inlet port of the oil pump 20 from the second accommodating cavity 16, the first filtering part 31 of the filtering mechanism 30 does not need to be connected with the oil inlet port of the oil pump 20 by using a pipeline, and the friction loss of the oil on the pipeline is avoided; in addition, the first filtering part 31 can filter out impurities, and thus the flow efficiency of the filtered oil is improved.
[0058] In an embodiment, the first filtering part 31 includes a filter screen structure, the filter screen structure is arranged in the first accommodating cavity 12, and the filter screen structure is configured to filter the oil flowing into the oil inlet port of the oil pump 20 from the first accommodating cavity 12. The filter screen structure can divide the first accommodating cavity 12 into an upper oil filtering space and a lower oil filtering space, the oil inlet port of the oil pump 20 is communicated with the lower oil filtering space, the oil filtered by the filter screen structure can flow into the oil inlet port of the oil pump 20 from the lower oil filtering space, and the oil inlet port of the oil pump 20 does not need to be connected with the first filtering part 31 by using a pipeline, the flow path of the oil is shortened, and the flow efficiency of the oil between the filtering mechanism 30 and the oil pump 20 is improved. In addition, the filter screen structure can filter out impurities, and the flowability of the filtered oil is improved.
[0059] In an embodiment, the oil pump 20 can pump the oil filtered by the filter screen structure of the filtering mechanism 30 into the second filtering part 32 of the filtering mechanism 30. In order to reduce the use of a pipeline to connect the second filtering part 32 of the filtering mechanism 30 with the oil outlet port of the oil pump 20, the inner cavity 11 includes a second accommodating cavity 16, the second accommodating cavity 16 is located between the oil outlet port and the oil cooler 40, the second accommodating cavity 16 is communicated with the oil outlet port; the second filtering part 32 of the filtering mechanism 30 is arranged in the second accommodating cavity 16.
[0060] Please refer to Figure 2 The second filtering part 32 of the filtering mechanism 30 is arranged in the second accommodating cavity 16 of the oil storage shell 10, the space of the oil storage shell 10 is reasonably utilized, and the oil pump 20, the second filtering part 32 of the filtering mechanism 30 does not need to be connected with the oil inlet port of the oil pump 20 by using a pipeline, and the friction loss of the oil on the pipeline is avoided; in addition, the second filtering part 32 can filter out impurities, and thus the flow efficiency of the filtered oil is improved.
[0061] The second filtering part 32 comprises a pressure filter, which is arranged in the second accommodating cavity 16. The filtered oil of the filter screen structure can directly flow into the second accommodating cavity 16 from the oil outlet port of the oil pump 20. The pressure filter is configured to filter the oil flowing out of the oil outlet port of the oil pump 20 and flowing through the second accommodating cavity 16.
[0062] The pressure filter is arranged in the second accommodating cavity 16, which is in communication with the oil outlet port of the oil pump 20. The oil pump 20 pumps the oil filtered by the first filtering part 31 of the filtering mechanism 30 from the oil outlet port to the second accommodating cavity 16. The oil in the second accommodating cavity 16 flows through the pressure filter, which filters the oil again. The oil flows between the oil pump 20 and the second accommodating cavity 16 without the use of a pipeline to connect the pressure filter with the oil outlet port of the oil pump 20. This reduces the friction loss of the oil on the pipeline and shortens the flow path of the oil, thereby improving the flow efficiency of the oil between the filtering mechanism 30 and the oil pump 20.
[0063] In an embodiment, the oil pump 20 is provided with an oil outlet interface, which is provided with an oil outlet port. The pressure filter comprises a second filter element. An end cover of the second filter element can be connected with the oil outlet joint of the oil pump 20, so that the pressure filter is connected with the oil pump 20. The oil pump 20 can pump the oil into the second accommodating cavity 16 in the inner cavity 11, thereby facilitating the second filter element to further filter the oil filtered by the filter screen structure, so as to filter out impurities. The flow efficiency of the oil after secondary filtration is improved.
[0064] Please refer to Figure 2 In order to cool the oil in the inner cavity 11, the inner cavity 11 comprises an oil cooling cavity 13, which is in communication with the second accommodating cavity 16. The oil cooler 40 is arranged in the oil cooling cavity 13. The oil cooler 40 is configured to exchange heat between the cooling medium in the oil cooler 40 and the oil in the oil cooling cavity 13.
[0065] Specifically, the pressure filter filters the oil flowing out of the oil outlet port of the oil pump 20 and flowing through the second accommodating cavity 16. The oil filtered by the pressure filter can flow to the oil cooling cavity 13, and then the cooling medium in the oil cooler 40 exchanges heat with the oil in the oil cooling cavity 13, so as to cool and cool the oil in the oil cooling cavity 13. Further, an oil outlet 15 can be arranged in the oil cooling cavity 13, so that the cooled and cooled oil can flow out of the oil outlet 15, and then flow into other mechanisms or devices, and flow and cool inside the other mechanisms or devices. The other mechanisms or devices can be a motor or a speed reducer. The cooled and cooled oil flows out of the oil outlet 15 and then flows into the interior of the motor or the speed reducer, so as to cool the motor or the speed reducer.
[0066] The filter is arranged along the outer edge of the oil cooler 40 in the second accommodating cavity 16, so as to reasonably utilize the space of the inner cavity 11, reduce the waste of the space of the inner cavity 11 by the filter, and thus reduce the space of the inner cavity 11 occupied by the filter, and effectively reduce the volume of the oil storage shell.
[0067] The oil cooler 40 has a long side facing the oil pump 20, and a short side connected to the long side. The filter comprises a filter channel and a filter element 320 arranged in the filter channel in a folded manner. The filter channel comprises a first filter channel and a second filter channel in communication with each other. The first filter channel is arranged in the gap between the long side of the oil cooler 40 and the oil pump 20. The second filter channel is arranged in the gap between the short side of the oil cooler 40 and the oil pump 20, and is bent relative to the first filter channel towards the short side of the oil cooler 40.
[0068] In an embodiment, the filter channel is L-shaped. Specifically, a part of the filter comprises the first filter channel arranged in the gap between the long side of the oil cooler 40 and the oil pump 20. Another part of the filter comprises the second filter channel arranged in the gap between the short side of the oil cooler 40 and the oil pump 20, and is bent relative to the first filter channel towards the short side of the oil cooler 40. The second filter channel is arranged in the gap between the short side of the oil cooler 40 and the oil pump 20, so as to reasonably utilize the space of the inner cavity 11, reduce the waste of the space of the inner cavity 11 by the second filter channel, and thus reduce the space of the inner cavity 11 occupied by the filter, and effectively reduce the volume of the oil storage shell.
[0069] Further, in an embodiment, the filter element 320 is filter paper, which is arranged in the filter channel in a folded manner. The inner side of the filter channel is provided with a filter paper support structure at a position corresponding to the bent part of the filter paper. The filter paper is arranged in the filter channel, which not only facilitates oil filtration, but also facilitates filter replacement. In order to bend and position part of the structure of the filter paper in the second filter channel, the inner side of the filter channel is provided with a filter paper support structure at a position corresponding to the bent part of the filter paper. The filter paper support structure guides the bending of part of the structure of the filter paper, so that part of the structure of the filter paper is bent and positioned in the second filter channel.
[0070] The oil flowing out of the oil outlet port of the oil pump 20 is filtered by the filter paper in the first filter channel and the second filter channel, and then flows into the oil cooling cavity 13. Then, the cooling medium in the oil cooler 40 exchanges heat with the oil in the oil cooling cavity 13, so as to cool and cool the oil in the oil cooling cavity 13.
[0071] In an embodiment, the oil cooler 40 is a submerged oil cooler, and the oil cooler 40 can be submerged in the oil, so that the cooling medium in the oil cooler 40 exchanges heat with the oil in the oil cooling cavity 13 to reduce the temperature of the oil in the inner cavity 11.
