Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a hybrid gearbox assembly, a cooling system, and a vehicle. Background Technology

[0002] The hybrid powertrain is a core component of a hybrid electric vehicle that integrates key components such as the engine, electric motor, transmission system, and power coupling mechanism into a single unit.

[0003] In related technologies, the housing of the hybrid gearbox assembly is made of aluminum alloy. Although aluminum alloy housing has good thermal conductivity, its structural design is already close to its limit in terms of lightweighting, and it is impossible to further reduce the weight. In other words, there is a problem with lightweighting the hybrid gearbox. Utility Model Content

[0004] In view of the above problems, this utility model provides a hybrid gearbox assembly. By using magnesium alloy and externally mounted hybrid gearbox cooling pipes, the weight of the hybrid gearbox assembly can be reduced while avoiding corrosion.

[0005] In a first aspect, according to an embodiment of the present application, the hybrid housing assembly includes a hybrid housing, an electronic control component, an oil cooler, and a first pipeline. The hybrid housing has an electronic control mounting cavity and a first through hole, the first through hole connecting the electronic control mounting cavity and the outside of the hybrid housing. The electronic control component is disposed in the electronic control mounting cavity, the oil cooler is disposed outside the hybrid housing, and the first pipeline is disposed outside the hybrid housing. One end of the first pipeline is connected to the electronic control component through the first through hole, and the other end is connected to the oil cooler. The hybrid housing is made of magnesium alloy.

[0006] According to the hybrid housing assembly of this application embodiment, in order to optimize the weight reduction of the hybrid housing assembly, the manufacturing material of the hybrid housing is changed from aluminum alloy to magnesium alloy. It is understood that the density of magnesium alloy is about 1.8 grams per cubic centimeter, and the density of aluminum alloy is about 2.7 grams per cubic centimeter. In this way, the hybrid housing of this application embodiment can reduce the weight by about 30% compared with the related technology, achieving a lightweight hybrid housing assembly. However, the cooling medium, such as cooling water or coolant, coming into contact with magnesium alloy can cause corrosion of magnesium alloy. Therefore, this application embodiment also externalizes the internal flow channels of the hybrid housing, that is, sets the internal flow channels of the hybrid housing on the outside of the hybrid housing to avoid direct contact between the cooling medium and the hybrid housing. In this way, while ensuring the lightweight of the hybrid housing, corrosion of the hybrid housing can be avoided.

[0007] Furthermore, the hybrid housing is provided with a first pipeline on its exterior. The internal structure of the first pipeline is the internal flow channel of the hybrid housing. One end of the first pipeline can pass through the outside of the first through hole and exit through the inside of the first through hole to extend into the electronic control mounting cavity and connect with the internal flow channel of the electronic control component. The other end of the first pipeline can be connected to the oil cooler. In this way, the cooling medium of the electronic control component can flow through the internal flow channel of the electronic control component, the first pipeline and the oil cooler in sequence, and then flow to the outside of the hybrid housing assembly.

[0008] In some embodiments, the hybrid housing is coated with a waterproof coating.

[0009] In the above embodiments, the direct contact between the cooling medium and the hybrid housing is further avoided, which could lead to corrosion problems in the hybrid housing.

[0010] In some embodiments, the electronic control component includes a water-cooled plate, an electronic control board, and a power device.

The cooling pipes pass through the support frame and are in thermal contact with the power device. The cooling pipes have cooling channels formed inside. The cover plate covers the hollow structure of the support frame and is connected to the support frame by friction welding.

[0013] In the above embodiments, contact between the cooling medium and the hybrid housing can be avoided, thus preventing corrosion of the hybrid housing.

[0014] In some embodiments, the electronic control assembly further includes a first seal, the water-cooled plate has a mounting groove that is thermally connected to the wall of the cooling channel, the power device extends into the mounting groove, and the first seal is disposed between the power device and the periphery of the groove opening of the mounting groove to seal the gap between the power device and the periphery of the groove opening of the mounting groove.

[0015] In the above embodiments, leakage of cooling medium can be avoided, which would affect the normal operation of the electronic control components.

[0016] In some embodiments, the hybrid assembly further includes a first adapter, which passes through the first through hole and connects the electronic control component and the first pipeline.

[0017] In the above embodiments, the reliability of the connection can be improved by using the first adapter, and leakage and corrosion of the magnesium alloy housing can be avoided.

[0018] In some embodiments, the first adapter has a first end and a second end, the outer peripheral surface of the first end is provided with a positioning groove, and a second sealing member is provided in the positioning groove. The second sealing member is used to seal the gap between the first end and the cooling channel of the electronic control component.

[0019] In the above embodiments, the sealing performance of the hybrid gearbox assembly can be improved, preventing leakage of cooling medium.

[0020] In some embodiments, the outer peripheral surface of the first end is provided with a first limiting portion, the first limiting portion abuts against the outer peripheral edge of the first through hole, and a third sealing member is provided between the first limiting portion and the outer peripheral edge of the first through hole.

[0021] In the above embodiments, the first adapter can be positioned by the first limiting part, and the sealing performance of the hybrid box assembly is further improved by the third sealing part.

[0022] In some embodiments, the hybrid housing further has a second through hole connecting the electrical control mounting cavity and the outside of the hybrid housing. The second through hole and the first through hole are located on the same side of the hybrid housing, and the second through hole is used to connect a water pump.

[0023] In the above embodiments, the cooling medium of the electronic control components enters and exits from the same side, which facilitates centralized pipeline arrangement and improves space utilization.

[0024] In some embodiments, the hybrid assembly further includes a positioning element disposed on the first pipeline, the hybrid housing is provided with a first positioning seat, and the positioning element is detachably connected to the first positioning seat.

[0025] In the above embodiments, the first pipeline can be set on the positioning member, and the positioning member can be connected to the first positioning seat, so that the first pipeline can be relatively positioned on the hybrid housing, thereby improving the arrangement stability of the first pipeline and avoiding the leakage of cooling medium due to the disconnection of the first pipeline by external force, which in turn leads to corrosion of the magnesium alloy housing.

[0026] In a second aspect, the cooling system according to an embodiment of this application includes the hybrid gearbox assembly described above.

Detailed Implementation

[0040] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0041] The hybrid powertrain is a core component of a hybrid electric vehicle that integrates key components such as the engine, electric motor, transmission system, and power coupling mechanism into a single unit.

[0042] In related technologies, the housing of the hybrid gearbox assembly is made of aluminum alloy. Although the aluminum alloy shell has good thermal conductivity, the structural design has reached near-extreme levels in terms of lightweighting.

[0043] Therefore, this utility model provides a hybrid housing assembly 100, which, by adopting an external magnesium alloy and hybrid housing cooling pipe 212, can reduce the weight of the hybrid housing assembly 100 while avoiding the problem of corrosion of the hybrid housing assembly 100.

[0044] like Figures 1 to 5 According to an embodiment of this application, the hybrid box assembly 100 includes a hybrid box body 10, an electronic control component 20, an oil cooler 30, and a first pipeline 40.

[0045] The hybrid housing 10 has an electrical control mounting cavity 11 and a first through hole. The first through hole connects the electrical control mounting cavity 11 and the outside of the hybrid housing 10. The electrical control component 20 is located in the electrical control mounting cavity 11, the oil cooler 30 is located outside the hybrid housing 10, and the first pipeline 40 is located outside the hybrid housing 10. One end of the first pipeline 40 is connected to the electrical control component 20 through the first through hole, and the other end is connected to the oil cooler 30. The hybrid housing 10 is made of magnesium alloy. This reduces the weight and cost of the hybrid housing assembly 100 and prevents corrosion of the hybrid housing 10.

[0046] Specifically, in the relevant technology, the hybrid housing 10 has an electronic control mounting cavity 11 and an internal flow channel. The electronic control mounting cavity 11 is located at the top of the hybrid housing 10, and an oil cooler 30 is provided at the bottom of the hybrid housing 10. The internal flow channel of the electronic control component 20 is connected to the oil cooler 30 through the internal flow channel, and the hybrid housing 10 is made of aluminum alloy.

[0047] In order to optimize the weight reduction of the hybrid housing assembly 100, this embodiment changes the manufacturing material of the hybrid housing 10 from aluminum alloy to magnesium alloy. It is understood that the density of magnesium alloy is about 1.8 grams per cubic centimeter, and the density of aluminum alloy is about 2.7 grams per cubic centimeter. Thus, the hybrid housing 10 of this embodiment can be reduced in weight by about 30% compared with related technologies, achieving a lightweight hybrid housing assembly 100. However, the cooling medium, such as cooling water or coolant, can cause corrosion of the magnesium alloy when in contact with it. Therefore, this embodiment also places the internal flow channels of the hybrid housing 10 externally, that is, sets the internal flow channels of the hybrid housing 10 on the outside of the hybrid housing 10 to avoid direct contact between the cooling medium and the hybrid housing 10. In this way, while ensuring the weight reduction of the hybrid housing 10, corrosion of the hybrid housing 10 can be avoided.

[0048] For example, the hybrid housing 10 is provided with a first pipe 40 on the outside. The internal structure of the first pipe 40 is the internal flow channel of the hybrid housing 10. One end of the first pipe 40 can be inserted from the outside of the first through hole and exited from the inside of the first through hole to extend into the electronic control mounting cavity 11 and connect with the internal flow channel of the electronic control assembly 20. The other end of the first pipe 40 can be connected to the oil cooler 30. In this way, the cooling medium of the electronic control assembly 20 can flow through the internal flow channel of the electronic control assembly 20, the first pipe 40 and the oil cooler 30 in sequence, and then flow to the outside of the hybrid housing assembly 100.

[0049] In summary, the hybrid housing 10 is made of magnesium alloy, which reduces the weight and cost of the hybrid housing assembly 100 compared to an aluminum alloy housing. Furthermore, by placing the cooling pipe 212 between the oil cooler 30 and the electronic control components 20 outside the hybrid housing 10, the risk of corrosion caused by direct contact between the cooling medium of the cooling pipe 212 and the magnesium alloy is reduced, ensuring the normal operation of the hybrid housing assembly 100.

[0050] Furthermore, in some embodiments of this application, the hybrid housing 10 is coated with a waterproof coating to further prevent the cooling medium from directly contacting the hybrid housing 10 and causing corrosion problems in the hybrid housing 10.

[0051] Specifically, the hybrid housing assembly 100 of this application embodiment can be applied to a vehicle. During vehicle operation, due to vibration and other reasons, the cooling pipes 212 located outside the hybrid housing 10 are prone to fatigue damage, resulting in leakage of the cooling medium. Therefore, in order to prevent the leaked cooling medium from directly contacting the hybrid housing 10, a waterproof coating can be applied to the hybrid housing 10 to separate the cooling medium from the hybrid housing 10 and avoid corrosion problems.

[0052] More specifically, a waterproof coating can be applied to the outer surface of the hybrid housing 10 to prevent the cooling medium leaking from the cooling pipe 212 from directly contacting the hybrid housing 10. In addition, a waterproof coating can also be applied to the inner surface of the electrical control mounting cavity 11 and the inner circumferential surface of the first through hole. It is understood that the first pipe 40 passes through the first through hole, and one end of the first pipe 40 is connected to the electrical control component 20 in the electrical control mounting cavity 11. When the first pipe 40 leaks, there is a risk of direct contact between the cooling medium and the inner surface of the electrical control mounting cavity 11 and the inner circumferential surface of the first through hole. Therefore, a waterproof coating is also required.

[0053] like Figures 1 to 4 In some embodiments of this application, the electronic control assembly 20 includes a water-cooled plate 21, an electronic control board, and a power device 22. The water-cooled plate 21 has a cooling channel connected to the first pipeline 40. The electronic control board is disposed on the water-cooled plate 21, and the power device 22 is disposed on the electronic control board and makes thermal contact with the outer wall of the cooling channel. The water-cooled plate 21 is made of die-cast aluminum alloy. This avoids the cooling medium from contacting the hybrid housing 10, which could lead to corrosion of the hybrid housing 10.

[0054] It is understandable that the electronic control component 20 has a heat dissipation requirement. The electronic control component 20 can be connected to the oil cooler 30 through the first pipe 40 and to the water pump 300 through the second pipe 90, thereby connecting to the vehicle's cooling system 1000 to achieve heat dissipation. However, in this process, the electronic control component 20 itself has the risk of cooling medium leakage. Therefore, the water-cooled plate 21 can be made of aluminum alloy material and die-cast to make the surface of the water-cooled plate 21 have a dense layer with good density and no risk of leakage.

[0055] It should be explained that the power device 22 is mounted on the electronic control board, which can be electrically connected to the motor inside the hybrid housing 10. Since the power device 22 generates a lot of heat, it can be made to make thermal contact with the outer wall of the cooling channel of the water-cooled plate 21 to dissipate heat from the power device 22.

[0056] like Figure 2In some embodiments of this application, the water-cooled plate 21 includes a support frame 211 with a hollow structure 2111, a cooling pipe 212, and a cover plate 213. The cooling pipe 212 passes through the support frame 211 and makes thermal contact with the power device 22. The cooling pipe 212 has a cooling channel inside. The cover plate 213 covers the hollow structure 2111 of the support frame 211 and is connected to the support frame 211 by friction welding. In this way, the cooling medium can be prevented from contacting the hybrid housing 10, which would cause corrosion of the hybrid housing 10.

[0057] It is understandable that the support frame 211 is made of aluminum alloy and the cooling pipe 212 is made of aluminum alloy. The support frame 211 has a hollow structure 2111. The cooling pipe 212 can be set in the hollow structure 2111 of the support frame 211 and integrally formed with the support frame 211 to improve the structural strength of the water-cooled plate 21 and realize the structural support for the electronic control board. In order to prevent the cooling pipe 212 from leaking and corroding the electronic control installation cavity 11, a cover plate 213 can be provided. The cover plate 213 is placed on the hollow structure 2111 of the support frame 211, and the cover plate 213 is connected to the support frame 211 by friction welding, thereby avoiding the leakage of the cooling pipe 212 and preventing corrosion of the magnesium alloy box.

[0058] In addition, the support frame 211 is frame-shaped and has multiple hollow structures 2111. In some specific examples, the support frame 211 has a side hollow structure 2111 and a bottom hollow structure 2111. The cover plate 213 includes a side cover plate 213 and a bottom cover plate 213. The cooling pipes 212 can pass through the hollow structures 2111 in the support frame 211. The side cover plate 213 can cover the side hollow structure 2111 and is connected to the edge of the side hollow structure 2111 by friction welding. The bottom cover plate 213 can cover the bottom hollow structure 2111 and is connected to the edge of the bottom hollow structure 2111 by friction welding, so as to avoid leakage of the cooling pipes 212 and avoid corrosion of the magnesium alloy box.

[0059] like Figure 2 In some embodiments of this application, the electronic control assembly 20 further includes a first sealing member 214. The water-cooled plate 21 has a mounting groove 2112 that is thermally connected to the wall of the cooling channel. The power device 22 extends into the mounting groove 2112. The first sealing member 214 is disposed between the power device 22 and the periphery of the groove opening of the mounting groove 2112 to seal the gap between the power device 22 and the periphery of the groove opening of the mounting groove 2112. In this way, leakage of the cooling medium can be avoided, which would affect the normal operation of the electronic control assembly 20.

[0060] For example, the top of the support frame 211 is provided with a mounting groove 2112, into which the power device 22 can extend. Heat can be transferred to the cooling medium in the cooling pipe 212 through the mounting groove 2112. When the cooling pipe 212 leaks, the cooling medium will leak through the mounting groove 2112 to the control board. Therefore, a first sealing element 214 can be provided. The first sealing element 214 is provided between the power device 22 and the periphery of the groove opening of the mounting groove 2112 to prevent the cooling medium from leaking and causing corrosion of the control board, thus ensuring the normal operation of the control assembly 20.

[0061] like Figures 1 to 4 In some embodiments of this application, the hybrid housing assembly 100 further includes a first adapter 50, which passes through a first through hole and connects the electronic control component 20 and the first pipeline 40. In this way, the reliability of the connection can be improved by the first adapter 50, and leakage and corrosion of the magnesium alloy housing can be avoided.

[0062] For example, one end of the first adapter 50 extends into the outside of the first through hole and extends out from the inside of the first through hole, and the first adapter 50 is disposed in the first through hole. One end of the first adapter 50 is connected to the cooling channel of the electronic control component 20, and the other end of the first adapter 50 is connected to the first pipe 40, so that the connection between the electronic control component 20 and the first pipe 40 can be structurally stable and reduce the occurrence of leakage.

[0063] In addition, in some specific examples, the hybrid housing 10 also has a second through hole, which connects the electronic control mounting cavity 11 and the outside of the hybrid housing 10. The hybrid housing assembly 100 also includes a second pipe 90 and a second adapter. One end of the second adapter extends into the second through hole from the outside and extends out from the inside of the second through hole. The second adapter is disposed in the second through hole. One end of the second adapter is connected to the cooling channel of the electronic control component 20, and the other end of the second adapter is connected to the second pipe 90. The second pipe 90 is connected to the water pump 300. The second adapter can make the connection between the electronic control component 20 and the second pipe 90 structurally stable and reduce the occurrence of leakage.

[0064] like Figure 4 In some embodiments of this application, the first adapter 50 has a first end 51 and a second end 52. The outer peripheral surface of the first end 51 is provided with a positioning groove, and a second sealing member 60 is provided in the positioning groove. The second sealing member 60 is used to seal the gap between the first end 51 and the cooling channel of the electronic control component 20. In this way, the sealing performance of the hybrid box assembly 100 can be improved, and the leakage of cooling medium can be avoided.

[0065] For example, the first end 51 of the first adapter 50 is inserted into one end of the cooling channel. The outer peripheral surface of the first end 51 is opposite to the inner wall surface of the cooling channel. A positioning groove is provided on the outer peripheral edge of the first end 51. A second sealing member 60 is provided in the positioning groove. The second sealing member 60 can abut against the inner surface of the positioning groove and the inner wall surface of the cooling channel, thereby avoiding the gap between the first end 51 and the inner wall surface of the cooling channel, preventing the cooling medium from leaking from the gap between the first end 51 and the cooling channel, and preventing corrosion of the magnesium alloy housing.

[0066] like Figure 4 In some embodiments of this application, a first limiting part 53 is provided on the outer peripheral surface of the first end 51. The first limiting part 53 abuts against the outer peripheral edge of the first through hole, and a third sealing member 70 is provided between the first limiting part 53 and the outer peripheral edge of the first through hole. In this way, the first adapter 50 can be positioned by the first limiting part 53, and the sealing performance of the hybrid box assembly 100 is further improved by the third sealing member 70.

[0067] For example, in conjunction with the foregoing, the first end 51 of the first adapter 50 enters from the outside of the first through hole and exits from the inside of the first through hole. At this time, the first limiting part 53 can abut against the outer periphery of the first through hole, restricting the first adapter 50 from continuing to enter, preventing the first adapter 50 from completely entering the electrical control mounting cavity 11, which would affect the assembly of the first adapter 50 and the first pipeline 40. Furthermore, a third sealing member 70 is provided on the outer periphery of the first limiting part 53. The third sealing member 70 can seal the gap between the first through hole and the first limiting part 53, preventing the cooling medium in the cooling channel of the electrical control component 20 from flowing outside the mixing box 10, thus preventing corrosion of the mixing box 10.

[0068] like Figures 1 to 4 In some embodiments of this application, the hybrid housing 10 also has a second through hole connecting the electronic control mounting cavity 11 and the outside of the hybrid housing 10. The second through hole and the first through hole are located on the same side of the hybrid housing 10. The second through hole is used to connect the water pump 300. In this way, the cooling medium of the electronic control component 20 enters and exits on the same side, which facilitates the centralized arrangement of pipelines and improves space utilization.

[0069] For example, the hybrid housing assembly 100 also includes a second pipe 90. The first pipe 40 and the second pipe 90 are arranged on the same side of the hybrid housing 10. The first pipe 40 can be connected to the cooling channel of the electronic control component 20 through a first through hole, and the second pipe 90 can be connected to the cooling channel of the electronic control component 20 through a second through hole. In this way, the cooling medium of the electronic control component 20 enters and exits on the same side, which facilitates the centralized arrangement of pipes and improves space utilization.

[0070] like Figure 1In some embodiments of this application, the hybrid housing assembly 100 further includes a positioning element 80, which is disposed on the first pipeline 40. The hybrid housing 10 is provided with a first positioning seat 12, and the positioning element 80 is detachably connected to the first positioning seat 12. It is understood that the first pipeline 40 can be disposed on the positioning element 80, and the positioning element 80 can be connected to the first positioning seat 12, so that the first pipeline 40 can be relatively positioned on the hybrid housing 10, thereby improving the arrangement stability of the first pipeline 40 and preventing the cooling medium from leaking due to the first pipeline 40 being disconnected by external force, which in turn leads to corrosion of the magnesium alloy housing.

[0071] For example, the positioning member 80 can be a positioning clamp, which is sleeved on the outer circumferential surface of the first pipeline 40 and can be fixedly connected to the first positioning seat 12 by fasteners, so as to greatly improve the arrangement stability of the first pipeline 40 and reduce the risk of disconnection.

[0072] like Figures 1 to 5 According to the embodiments of this application, the cooling system 1000 includes the hybrid box assembly 100 in the above embodiments. By applying the hybrid box assembly 100 in the above embodiments, the weight of the cooling system 1000 can be reduced while avoiding corrosion caused by contact between the magnesium alloy box and the cooling medium.

[0073] like Figure 1 In some embodiments of this application, the cooling system 1000 further includes a radiator 200 and a water pump 300. The radiator 200 is connected to the water pump 300 and the oil cooler 30. The water pump 300 is connected to the cooling channel of the electronic control component 20. The radiator 200 and the water pump 300 are located on the same side of the hybrid housing 10. In this way, the radiator 200 and the water pump 300 can be arranged on the same side of the hybrid housing 10, which facilitates the centralized arrangement of structural components and improves space utilization.

[0074] For example, the first pipe 40, the second pipe 90, the radiator 200, and the water pump 300 are all arranged on the same side of the hybrid housing 10. In this way, the circulation structure of the cooling medium can be concentrated on the same side of the hybrid housing 10, thereby improving space utilization.

[0075] It needs to be explained that, such as Figure 5 The radiator 200, water pump 300, second pipeline 90, electronic control component 20, first pipeline 40, and oil cooler 30 are sequentially connected to form a circulation loop. The cooling medium circulates in the circulation loop to dissipate heat from the electronic control component 20. The radiator 200 is also connected to an expansion tank 400, which stores the cooling medium and replenishes the circulation loop with cooling medium.

[0076] like Figure 1In some embodiments of this application, the hybrid housing 10 is provided with a second positioning seat 13, and the pump body of the water pump 300 is connected to the second positioning seat 13 by fasteners; it is understood that the water pump 300 can be fixed on the hybrid housing 10 by the second positioning seat 13 to improve the arrangement stability of the first water pump 300 and avoid leakage caused by external force, which would lead to corrosion of the magnesium alloy housing.

[0077] According to an embodiment of this application, the vehicle includes the cooling system 1000 described in the above embodiments; by applying the cooling system 1000 described in the above embodiments, the weight of the vehicle can be reduced and the energy efficiency of the vehicle can be improved.

[0078] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or a point connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts.
