[0032] To address the issues of long wiring distances, high flow resistance, and low heat dissipation efficiency in electric hybrid enclosures, this application provides an electric hybrid enclosure assembly 100. Figure 1 This is a schematic cross-sectional view of an electric hybrid gearbox assembly. Figure 2 This is an exploded view of the structure of an electric hybrid gearbox assembly, as shown below. Figure 1 and Figure 2 As shown, the electric hybrid gearbox assembly 100 includes: a hybrid gearbox housing assembly 10, the hybrid gearbox housing assembly 10 including a front housing 11, a middle housing 12 and a rear housing 13, the front housing 11 and the middle housing 12 enclose a gear cavity 15, the rear housing 13 and the middle housing 12 enclose a motor cavity 16, and a generator and a drive motor are provided in the motor cavity 16;

[0033] Electrical control box housing 17, wherein electrical components are disposed within the electrical control box housing 17; and

[0034] The cooling water channel assembly 18 includes a first cooling water channel 181, a second cooling water channel 182, and a sealing element 187. The first cooling water channel 181 is integrally formed with the middle shell 12, and the second cooling water channel 182 is disposed inside the electrical control box housing 17. The bottom of the electrical control box housing 17 is provided with a second outlet 1821 of the second cooling water channel 182. The middle shell 12 is provided with a first inlet 1811 connected to the first cooling water channel 181, and the first inlet 1811 and the second outlet 1821 are sealed together by the sealing element 187.

[0035] The technical solution of this application addresses the problem by providing a cooling water channel assembly 18 inside the mixing tank housing assembly 10. The cooling water channel assembly 18 includes a first cooling water channel 181 and a second cooling water channel 182. The first cooling water channel 181 is integrally formed with the middle shell 12, and the second cooling water channel 182 is located inside the electrical control box housing 17. Since the first cooling water channel 181 is integrally formed with the middle shell 12, the problems of long wiring path, high flow resistance, and low heat dissipation efficiency of the heat dissipation channel can be solved.

[0036] To make the technical solution, purpose and advantages of this application clearer, the technical solution of this application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Meanwhile, for ease of understanding, the mixing tank housing assembly 10 is used as a reference object for orientation. The mixing tank housing assembly 10 is placed horizontally, the direction closer to the front shell 11 is defined as the front, the direction closer to the rear shell 13 is defined as the rear, the direction of gravity is positioned as the bottom, and the opposite direction is the top.

[0038] In the technical solution of this application, the housing assembly 10 is the basic part, which can accommodate functional components, and cooling water channels can also be provided inside the housing.

[0039] In some implementation schemes, such as Figure 1 and Figure 2 As shown, the mixing tank housing assembly 10 includes a front shell 11, a middle shell 12 and a rear shell 13. The front shell 11 and the middle shell 12 enclose a gear cavity 15, and the rear shell 13 and the middle shell 12 enclose a motor cavity 16. A generator and a drive motor are provided in the motor cavity 16. An electrical control box housing 17 is provided in the electrical control box housing 17. Electrical components are provided in the electrical control box housing 17.

[0040] For details, please continue reading Figure 2 The front shell 11 is a semi-shell shape with a recessed area. The middle shell 12 is located between the front shell 11 and the rear shell 13 and plays an important supporting role. The rear shell 13 is also a semi-shell shape and has a recessed area opposite to the recessed area of ​​the front shell 11. The front shell 11 and the middle shell 12 enclose a gear cavity 15 for accommodating the transmission assembly. The rear shell 13 and the middle shell 12 enclose a motor cavity 16. The motor cavity 16 can accommodate a generator and a drive motor.

[0041] In addition, the electrical control box housing 17 is located on top of the mixing box housing assembly 10 and has a box-shaped structure. Electrical components are installed inside the electrical control box housing 17, which can control the operation of the generator and the drive motor.

[0042] In the above scheme, the configuration of the mixing tank shell assembly 10, including the front shell 11, the middle shell 12 and the rear shell 13, is a relatively mature technical solution. This shell structure has a mature and stable process.

[0043] To address the issues of long wiring distances, high flow resistance, and low heat dissipation efficiency of external cooling water channels in current hybrid gearboxes, this application's technical solution includes a cooling water channel assembly 18.

[0044] In some implementations, such as Figure 1 As shown, the cooling water channel assembly 18 includes a first cooling water channel 181, a second cooling water channel 182, and a sealing element 187. The first cooling water channel 181 is integrally formed with the middle shell 12, and the second cooling water channel 182 is disposed inside the electrical control box housing 17. The bottom of the electrical control box housing 17 is provided with a second outlet 1821 of the second cooling water channel 182, and the middle shell 12 is provided with a first inlet 1811 connected to the first cooling water channel 181. The first inlet 1811 and the second outlet 1821 are sealed by the sealing element 187.

[0045] Specifically, Figure 3 Please refer to the following diagram as a side view of an electric hybrid gearbox assembly. Figure 2 and Figure 3The first cooling water channel 181 is located inside the middle shell 12 and between the generator mounting position and the drive motor mounting position in the motor cavity 16. The second cooling water channel 182 is located inside the electrical control box housing 17, and the electrical control box housing 17 is mounted on the upper end of the middle shell 12. Therefore, the connection between the electrical control box housing 17 and the middle shell 12 is equipped with a sealing element 187 and a connecting element 188 for sealing connection to prevent water leakage.

[0046] The first cooling water channel 181 is located inside the middle shell 12 and is integrally formed with the middle shell 12. In particular, the first cooling water channel 181 is located between the generator mounting position and the drive motor mounting position in the motor cavity 16. This cooling water channel is relatively close to the heat source, which is beneficial to improving heat dissipation efficiency.

[0047] As is well known, heat dissipation of the generator and drive motor in the hybrid gearbox is one of the difficulties in heat dissipation of the hybrid gearbox shell. The first cooling water channel 181 is set inside the motor cavity 16, which is conducive to heat dissipation of the motor cavity 16, can greatly improve heat dissipation efficiency, and can improve the overall structural compactness of the hybrid gearbox.

[0048] In some implementations, such as Figure 1 As shown, the first cooling water channel 181 is vertically arranged inside the middle shell 12 and located between the generator and the drive motor.

[0049] The first cooling water channel 181 includes a Y-shaped portion 1813 and an L-shaped portion 1815. The lower end of the Y-shaped portion 1813 is connected to the upper end of the L-shaped portion 1815. One side of the opening end of the Y-shaped portion 1813 is connected to the first water inlet 1811. The lower part of the L-shaped portion 1815 is connected to the middle shell 12.

[0050] One of the openings of the Y-shaped portion 1813 away from the L-shaped portion 1815 is a process reservation position 18131. The top of the process reservation position 18131 is provided with a sealing portion 18132, which is an annular step used to seal the process reservation position 18131.

[0051] For details, please continue reading Figure 1 The first cooling water channel 181 is disposed inside the middle shell 12 and forms an integral structure with the middle shell 12. The Y-shaped part 1813 is located in the upper half of the first cooling water channel 181, and the L-shaped part 1815 is located in the lower half of the first cooling water channel 181. The Y-shaped part 1813 and the L-shaped part 1815 are combined vertically to form an integral channel communication structure. This channel communication structure can accommodate and transport cooling water, thereby displacing and transporting the heat of the shell away from the shell through the cooling water.

[0052] The top of the left branch of the opening end of the Y-shaped part 1813 is the first cooling water channel 181 located at the first water inlet 1811 of the middle shell 12, while the right branch of the opening end of the Y-shaped part 1813 is the process reserved position 18131. The process reserved position 18131 is a mold core pull provided in the middle shell 12 during the molding process to form the channel below the opening of the Y-shaped part 1813. After the mold core pull is removed, a channel structure is formed. Therefore, the upper end of the process reserved position 18131 passes through the shell of the middle shell 12. If it is not sealed, the shell of the middle shell 12 will inevitably leak water. Therefore, a sealing part 18132 is provided at the upper end of the process reserved position 18131. The sealing part 18132 is a cylindrical step and its diameter is larger than the diameter of the lower end of the process reserved position 18131. Therefore, after the sealing material is installed in the process reserved position 18131, it can be effectively sealed and will not leak water.

[0053] In some implementation schemes, such as Figure 1 As shown, the lower half of the first cooling water channel 181 is an L-shaped portion 1815. The vertical portion of the L-shaped portion 1815 is connected to the lower end of the Y-shaped portion 1813. The straight portion at the lower end of the L-shaped portion 1815 is the water outlet channel of the first cooling water channel 181, which can discharge the cooling water in the first cooling water channel 181 to the outside of the middle shell 12.

[0054] In the above scheme, the first cooling water channel 181 includes a Y-shaped portion 1813 and an L-shaped portion 1815. This structural design is based on selecting the optimal straight path by relying on the internal structure of the middle shell 12. It is necessary to ensure that the first cooling water channel 181 is located inside the middle shell 12 while also taking into account the feasibility of the shell forming process. Therefore, the structure and shape of the first cooling water channel 181 are more suitable for the structure of the middle shell 12, and can balance the existing layout of related components and the achievement of cooling goals.

[0055] The first cooling water channel 181 is located in the middle of the cooling water channel assembly 18, the second cooling water channel 182 is located at the top of the cooling water channel assembly 18, and the connector 188 is also installed at the connection between the first cooling water channel 181 and the second cooling water channel 182 and connects the two.

[0056] Specifically, such as Figure 1 As shown, the second cooling water channel 182 is located in and passes through the electrical control box housing 17. The electrical control box housing 17 is installed at the upper end of the middle shell 12. The second cooling water channel 182 inside the middle shell 12 is connected to the first cooling water channel 181. A sealing element 187 and a connecting element 188 are installed at the connection between the upper end of the electrical control box housing 17 and the middle shell 12 for sealing connection. That is, a sealing ring 1871 is installed between the second cooling water channel 182 and the first cooling water channel 181, and at least two connecting elements 188 are used to connect and seal the electrical control box housing 17 and the middle shell 12 to prevent water leakage.

[0057] In the above scheme, the second cooling water channel 182 is set in the electrical control box housing 17 and runs through the electrical control box housing 17. Compared with the existing scheme, this structure eliminates the connection part between the water channel of the housing assembly 10 and the electrical control box housing 17. This structure not only reduces the connection part between the housing assembly 10 and the electrical control box housing 17, but also reduces the space occupied by the housing assembly 10 and the electrical control box housing 17, and shortens the length of the cooling water channel, which can improve cooling efficiency and reduce process costs.

[0058] The end of the cooling water channel assembly 18 is the third cooling water channel 183, which is connected to the first outlet of the first cooling water channel 181. The third cooling water channel 183 transports cooling water into the next stage.

[0059] In some implementations, such as Figure 2 As shown, the electric drive hybrid gearbox assembly 100 also includes an oil cooler housing 19, which is installed in the lower part of the gear cavity 15. The cooling water channel assembly 18 also includes a third cooling water channel 183, which is disposed inside the oil cooler housing 19. The third cooling water channel 183 is connected to the first cooling water channel 181. The bottom of the oil cooler housing 19 is provided with a third outlet 1831 of the third cooling water channel 183.

[0060] Specifically, the oil cooler housing 19 is located at the bottom of the mixing chamber housing assembly 10, specifically below the gear cavity 15 and close to the bottom of the middle shell 12. The oil cooler housing 19 has a box-shaped structure with an internal cooling oil receiving cavity. A through-type third cooling water channel 183 is located in the middle of the oil cooler housing 19. The oil cooler housing 19 utilizes this third cooling water channel 183 to dissipate heat from the cooling oil inside its receiving cavity, and also serves as part of the cooling water channel assembly 18. The bottom of the oil cooler housing has an outlet for the third cooling water channel 183, which can deliver cooling water to the next unit. Therefore, the oil cooler housing 19 is a dual-function component.

[0061] There are also other implementation methods, such as Figure 2 As shown, the seal 187 includes a sealing ring 1871, which is installed at the connection between the first cooling water channel 181 and the third cooling water channel 183, and at the connection between the first cooling water channel 181 and the second cooling water channel 182. The middle shell 12 is provided with a sealing groove 1872, which accommodates the sealing ring 1871. The cooling water channel assembly 18 also includes a connector 188, which connects the first cooling water channel 181 and the second cooling water channel 182, and the first cooling water channel 181 and the third cooling water channel 183.

[0062] Specifically, the sealing element 187 can be a sealing ring 1871, and the connecting element 188 can be a bolt. At the connection of the first cooling water channel 181, the second cooling water channel 182, and the third cooling water channel 183, that is, at the water inlet end and water outlet end of the first cooling water channel 181 and the position where it connects with the shell of the middle shell 12, a sealing groove 1872 is provided. The sealing groove 1872 is an annular groove structure, and the sealing ring 1871 is placed in the sealing groove 1872. Similarly, the electrical control box shell 17 and the oil cooler shell 19 are provided with multiple connection holes.

[0063] A sealing ring 1871 is installed between the sealing grooves 1872 of the middle shell 12. Multiple connecting bolts are inserted through the connection holes of the electrical control box shell 17 and the oil cooler shell 19 to connect and seal the electrical control box shell 17 with the middle shell 12 and the oil cooler shell 19 with the middle shell 12, thereby connecting the second cooling water channel 182, the first cooling water channel 181 and the third cooling water channel 183 without leakage.

[0064] In the above scheme, the third cooling water channel 183 is located inside the oil cooler housing 19 and is directly connected to the first cooling water channel 181. Compared with the existing scheme, this structure eliminates the connection part between the water channel of the housing assembly 10 and the oil cooler housing 19. This structure reduces the connection part between the housing assembly 10 and the oil cooler housing 19, reduces the space occupied by the housing assembly 10 and the oil cooler housing 19, and shortens the length of the cooling water channel. Therefore, it can improve the cooling efficiency of the housing assembly 10 and the oil cooler housing 19 themselves and reduce the process cost.

[0065] The electric hybrid gearbox assembly 100 also includes a cooling circulation system (not shown). In the technical solution of this application, the cooling circulation system (not shown) drives cooling water into the cooling water channel assembly 18. The cooling circulation system (not shown) includes a water pump, a water tank, and a heat exchanger. The water pump, water tank, heat exchanger, and cooling water channel assembly 18 are connected to form a closed loop.

[0066] Specifically, the water pump drives the cooling water in the water tank to enter the second cooling water channel 182 inside the electrical control box housing 17. The water flows through the second outlet 1821 of the second cooling water channel 182 and then through the first inlet 1811 of the first cooling water channel 181 into the first cooling water channel 181. Next, the cooling water flows through the outlet of the first cooling water channel 181 into the third cooling water channel 183 inside the oil cooler housing 19. Finally, the cooling water flows through the outlet of the third cooling water channel 183 and then through the heat exchanger. After the cooling water temperature has been reduced by the heat exchanger, it flows back to the water tank. This cycle repeats to reduce the temperature of the middle shell 12, thereby reducing the temperature of the generator and drive motor, thus ensuring the normal operation of the generator and drive motor and preventing high temperature overload.

[0067] In the technical solution of this application, the first cooling water channel 181 can also be formed by processing or other methods, the sealing element 187 can be a sealing device and process other than the sealing ring 1871, the mixing tank housing assembly 10 can be made by die casting or other processes, the mixing tank housing assembly 10 can be made of aluminum alloy or other materials, and the connecting element 188 can be bolts or other connecting parts, and there are no restrictions on these.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
