[0055] For a better understanding of the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0056] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

The singular forms "a", "the" and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0058] It should be understood that the term "and / or" used herein is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0059] An electric vehicle refers to a vehicle powered by an on-vehicle power source and driven by an electric motor to drive the wheels, which has good economy and less environmental pollution. Therefore, the development prospect of electric vehicles is widely optimistic. With the continuous development of electric vehicles, the configuration of electric vehicles is getting higher and higher, and various functional components on the vehicle body are also increasing continuously, resulting in the space inside the whole vehicle becoming more and more compact. Therefore, the integration requirements for each component of the whole vehicle are also getting higher and higher. The power distribution and charging integration structure in an electric vehicle includes components such as a transmission assembly and a power distribution and charging assembly. Among them, the power distribution and charging assembly is usually arranged in the front engine compartment and is far from other components, which not only makes it difficult to connect with other components, but also results in poor integration of the power distribution and charging integration structure.

[0060] To solve the above technical problems, as Figure 1 shown, the embodiments of the present application provide a power distribution and charging integration structure and a vehicle including the power distribution and charging integration structure. The power distribution and charging integration structure may include a transmission assembly 2 and a power distribution and charging assembly 1. Among them, the power distribution and charging assembly 1 may be installed on the transmission assembly 2.

[0061] In this embodiment, by installing the power distribution and charging assembly 1 on the transmission assembly 2, the physical integration of the power distribution and charging assembly 1 and the transmission assembly 2 is realized. Compared with the related art in which the power distribution and charging assembly and the transmission assembly are separately arranged, the number of mounting brackets required for the power distribution and charging assembly 1 can be reduced in the embodiments of the present application, the integration degree and space utilization rate of the whole vehicle can be improved. At the same time, it is also convenient to connect the power distribution and charging assembly 1 and the transmission assembly 2, and the length and quantity of the wires used for their connection can be reduced, so that the effect of reducing costs can also be achieved.

[0062] Among them, the transmission assembly 2 is used to fix and shift gears to change the transmission ratio between the output shaft and the input shaft of the vehicle, and the charging and power distribution assembly 1 is used to convert the DC power supply into the current and voltage required for vehicle charging.

[0063] In the above embodiments, at the same time, as Figure 2 shown, the transmission assembly 2 may further include a transmission housing 21 and a motor controller 22 fixedly connected. The charging and power distribution assembly 1 may be fixedly connected to the motor controller 22. Along the first direction, the charging and power distribution assembly 1, the motor controller 22, and the transmission housing 21 are sequentially stacked.

[0064] In this embodiment, the transmission housing 21 and the motor controller 22 are fixedly connected, so that the charging and power distribution assembly 1 is fixedly connected to the motor controller 22, thereby enabling the charging and power distribution assembly 1 to be installed on the transmission assembly 2, realizing the physical integration of the charging and power distribution assembly 1 and the transmission assembly 2. And the charging and power distribution assembly 1 is connected to the transmission assembly 2 through the motor controller 22, which can improve the connection reliability between the charging and power distribution assembly 1 and the transmission assembly 2, and avoid the separation of the charging and power distribution assembly 1 and the transmission assembly 2 during vehicle driving.

[0065] Among them, the first direction in the embodiments of the present application may be the height direction of the transmission assembly 2.

[0066] In the above embodiments, when the above charging and power distribution integrated structure is installed in a vehicle, it can improve the overall integration of the vehicle and reduce the assembly difficulty and cost of the vehicle.

[0067] In a specific embodiment, as Figure 3 shown, the charging and power distribution assembly 1 may include a first housing 11, the motor controller 22 may include a second housing 221, and the first housing 11 and the second housing 221 are fixedly connected. There may be an accommodation space between the first housing 11 and the second housing 221.

[0068] In this embodiment, the charging and power distribution assembly 1 may include a first housing 11, and the components inside the charging and power distribution assembly 1 may be installed in the first housing 11. While the first housing 11 plays a bearing role for it, it can also play a protective role. The motor controller 22 may have a second housing 221, and the charging and power distribution assembly 1 and the motor controller 22 may be fixedly connected through the first housing 11 and the second housing 221. At the same time, there may be an accommodation space between the first housing 11 and the second housing 221, and the components in the charging and power distribution assembly 1 and the motor controller 22 may be installed in this accommodation space.

[0069] In the above embodiments, the first housing 11 may not be provided with a bottom wall on the side facing the second housing 221, and the second housing 221 may not be provided with a top wall on the side facing the first housing 11. After the first housing 11 and the second housing 221 are fixedly connected, the volume of the accommodation space can be increased, which is convenient for the internal components of the first housing 11 and the second housing 221 to be interconnected, and the materials required for manufacturing parts can be reduced, achieving the effect of cost reduction. At the same time, after the first housing 11 and the second housing 221 are covered with each other, the components located in the accommodation space can be protected from collision or contamination, meeting the usage requirements of the power distribution and charging assembly 1 and the motor controller 22.

[0070] In a specific embodiment, as Figures 3 to 5 shown, a first step portion 12 may be circumferentially provided at one end of the first housing 11 facing the second housing 221, and a second step portion 222 may be circumferentially provided at one end of the second housing 221 facing the first housing 11. The first housing 11 and the second housing 221 may be fixedly connected through the first step portion 12 and the second step portion 222.

[0071] In this embodiment, the first housing 11 and the second housing 221 can be fixedly connected through the first step portion 12 and the second step portion 222, which can improve the connection reliability between the first housing 11 and the second housing 221, and prevent the first housing 11 and the second housing 221 from separating during vehicle driving. Moreover, the first step portion 12 is circumferentially provided on the side of the first housing 11 facing the second housing 221, and the second step portion 222 is circumferentially provided on the side of the second housing 221 facing the first housing 11, which can increase the contact area between the first step portion 12 and the second step portion 222, so as to further improve the connection reliability and stability between the first housing 11 and the second housing 221.

[0072] In the above embodiments, a plurality of corresponding mounting holes may also be provided on the first step portion 12 and the second step portion 222, so that the first step portion 12 and the second step portion 222 can be connected by screwing. At the same time, Watt glue may be coated between the first step portion 12 and the second step portion 222. Watt glue has good viscosity and chemical stability, and is non-toxic and odorless, which can improve the sealing effect between the first step portion 11 and the second step portion 222, and prevent dust or sewage from entering the interiors of the first housing 11 and the second housing 221. In addition, a specific degreaser is used to facilitate the removal of the Watt glue, so that the disassembly and assembly of the first housing 11 and the second housing 221 can be realized, which is convenient for subsequent maintenance or replacement.

[0073] In the above embodiments, to ensure the smooth connection between the first stepped portion 12 and the second stepped portion 222 and the glue application requirements, the flatness and surface roughness of the first stepped portion 12 and the second stepped portion 222 need to be consistent. Among them, the flatness of the first stepped portion 12 and the second stepped portion 222 can be 0.3, and the surface roughness can be Ra3.2.

[0074] In other embodiments, the flatness and surface roughness of the first stepped portion 12 and the second stepped portion 222 can also be adjusted according to actual situations.

[0075] In a specific embodiment, such as Figure 3 and Figure 6 as shown, the charging and power distribution assembly 1 can at least include a distribution box 13, a vehicle-mounted charger 14, and a power conversion device 15. Among them, the distribution box 13, the vehicle-mounted charger 14, and the power conversion device 15 can be distributed along the second direction.

[0076] In this embodiment, the charging and power distribution assembly 1 can include components such as a distribution box 13, a vehicle-mounted charger 14, and a power conversion device 15. Among them, the distribution box 13 is the high-voltage power distribution unit of the vehicle, the function of the vehicle-mounted charger 14 is to convert household single-phase alternating current or industrial three-phase alternating current into direct current to charge the vehicle's battery, and the function of the power conversion device 15 is to convert the high-voltage direct current output by the battery into low-voltage direct current. In this embodiment, to facilitate the connection between the charging and power distribution assembly 1 and the motor controller 22, the first housing 11 of the charging and power distribution assembly 1 needs to match the shape of the second housing 221. Therefore, the distribution box 13, the vehicle-mounted charger 14, and the power conversion device 15 are distributed along the second direction so that the installation positions of the above components are convenient for matching the first housing 11.

[0077] Among them, the second direction in the embodiments of the present application can be the length direction or the width direction of the transmission assembly 2.

[0078] In a specific embodiment, such as Figures 3 to 6 as shown, the first housing 11 can include a first accommodation cavity 111 and a second accommodation cavity 112 distributed along the second direction. The distribution box 13 is accommodated in the first accommodation cavity 111, and the vehicle-mounted charger 14 and the power conversion device 15 are accommodated in the second accommodation cavity 112.

[0079] In this embodiment, the first housing 11 can include a first accommodation cavity 111 and a second accommodation cavity 112 distributed along the second direction, and the distribution box 13, the vehicle-mounted charger 14, and the power conversion device 15 are respectively accommodated in different accommodation cavities, which is convenient for the installation of the distribution box 13, the vehicle-mounted charger 14, and the power conversion device 15 and avoids the influence caused by mutual interference between components.

[0080] In a specific embodiment, such as Figure 3 andFigure 6 As shown, the first accommodating cavity 111 may have a first opening 113 , and the second accommodating cavity 112 may have a second opening 114 . Along the first direction, the first opening 113 faces away from the motor controller 22 , and the second opening 114 faces toward the motor controller 22 .

[0081] In this embodiment, the first accommodating chamber 111 has a first opening 113 and the second accommodating chamber 112 has a second opening 114, so that the components can be installed through the first opening 113 and the second opening 114. The first accommodating chamber 111 is used to accommodate the distribution box 13, so the first opening 113 is set away from the motor controller 22 along the first direction to avoid the components in the motor controller 22 from affecting the normal use of the distribution box 13, and it is convenient to connect the distribution box 13 with other components. At the same time, the second accommodating chamber 112 is used to accommodate the vehicle charger 14 and the power conversion device 15, so the second opening 114 is set toward the motor controller 22 along the first direction, so that the vehicle charger 14 and the power conversion device 15 are connected to the components in the motor controller 22. The first opening 113 and the second opening 114 are staggered, which can further separate the distribution box 13 from the vehicle charger 14 and the power conversion device 15 to avoid mutual influence.

[0082] In a specific embodiment, Figure 3 and Figure 6 As shown, the charging and distribution assembly 1 may also be provided with a first cover plate 115 and a second cover plate 116, wherein the first cover plate 115 covers the first opening 113, and the second cover plate 116 covers the second opening 114. The cross-sectional area of ​​the first cover plate 115 is larger than the cross-sectional area of ​​the first opening 113, and / or the cross-sectional area of ​​the second cover plate 116 is smaller than the cross-sectional area of ​​the second opening 114.

[0083] In this embodiment, the charging and distribution assembly 1 may be provided with a first cover plate 115, which is used to cover the first opening 113 to seal the first opening 113, thereby protecting the distribution box 13 accommodated in the first accommodating cavity 111 and extending the service life of the distribution box 13. The cross-sectional area of ​​the first cover plate 115 is larger than the cross-sectional area of ​​the first opening 113, thereby improving the covering and sealing effect of the first cover plate 115 on the first opening 113. The first cover plate 115 may be screwed to the outer wall of the first shell 11 to improve the connection reliability between the first cover plate 115 and the first shell 11, and facilitate the disassembly and assembly of the first cover plate 115 and the first shell 11.

[0084] Meanwhile, the charging and discharging assembly 1 can also be provided with a second cover plate 116 for covering the second opening 114, so as to protect the vehicle-mounted charger 14 and the power conversion device 15 accommodated in the second opening 114 and extend their service lives. And the second cover plate 116 is smaller than the cross-sectional area of the second opening 114, so that when the second cover plate 116 covers the second opening 114, the second opening 114 is not completely sealed, which is convenient for wire connection between the vehicle-mounted charger 14 and the power conversion device 15 in the second accommodation cavity 112 and the corresponding components in the motor controller 22. Wherein, the second cover plate 116 can be screwed to the inner wall of the first housing 11 to improve the connection reliability between the second cover plate 116 and the first housing 11 and facilitate the disassembly and assembly of the second cover plate 116 and the first housing 11.

[0085] In a specific embodiment, as Figure 3 shown, the charging and discharging assembly 1 can have a first water nozzle 16. One end of the first water nozzle 16 is located inside the first housing 11, and the other end penetrates through the first housing 11. The motor controller 22 can have a second water nozzle 223. One end of the second water nozzle 223 is located inside the second housing 221, and the other end penetrates through the second housing 221. The first water nozzle 16 is communicated with the second water nozzle 223.

[0086] In this embodiment, the motor controller 22 has a second water nozzle 223, and the second water nozzle 223 is communicated with the cooling water circuit of the transmission assembly. Therefore, the first water nozzle 16 of the charging and discharging assembly 1 is communicated with the second water nozzle 223 of the motor controller 22, so that the first water nozzle 16 of the charging and discharging assembly 1 can be communicated with the cooling water circuit of the transmission assembly through the second water nozzle 223. Compared with the charging and discharging assembly in the related documents, the charging and discharging assembly 1 in the embodiment of the present application can share the same cooling water circuit with the transmission assembly, so as to reduce the layout of the cooling water circuit, reduce the number of parts, and further improve the integration degree of the vehicle. And one end of the first water nozzle 16 is located inside the first housing 11, so as to cool the components inside the first housing 11, and the other end penetrates through the first housing 11, which is convenient for connecting with the second water nozzle 223 of the motor controller 22 and indirectly connecting to the cooling water circuit of the transmission assembly to ensure the normal use of the first water nozzle 16 for water inlet or drainage.

[0087] In the above embodiment, at the same time, as Figure 7 shown, the outer diameter of the first water nozzle 16 can be smaller than or equal to the inner diameter of the second water nozzle 223. When the first water nozzle 16 is connected to the second water nozzle 223, the first water nozzle 16 can be inserted into the second water nozzle 223. And a recess 161 can be provided on the first water nozzle 16, and a sealing ring 20 can be sleeved on the recess 161. When the first water nozzle 16 is inserted into the second water nozzle 223, the sealing ring 20 can abut against the inner wall of the second water nozzle 223 to achieve a sealing effect.

[0088] In other embodiments, the second water nozzle can also be inserted into the first water nozzle, and the recess and the sealing ring can also be arranged on the second water nozzle (not shown in the figure). In the embodiments of the present application, the specific dimensions, tolerance requirements, and arrangement positions of the first water nozzle 16, the second water nozzle 223, the recess 161, and the sealing ring 20 are not limited and can be adjusted according to actual usage conditions.

[0089] In a specific embodiment, such as Figure 3 and Figure 4 As shown, the charging and discharging assembly 1 can also be provided with a third water nozzle 17. One end of the third water nozzle 17 located inside the first housing is connected to the first water nozzle, and the end of the third water nozzle located outside the first housing has a bent portion. The third water nozzle 17 is connected to the vehicle's overall cooling water circuit through the bent portion 171.

[0090] In this embodiment, the charging and discharging assembly can also be provided with a third water nozzle 17. One end of the third water nozzle 17 located inside the first housing 11 can be connected to the first water nozzle 16, and the end of the third water nozzle 17 located outside the first housing 11 can be connected to the vehicle's overall cooling water circuit. Thus, under the combined action of the first water nozzle 16 and the third water nozzle 17, the charging and discharging assembly 1 can achieve the circulation of the coolant, and both the liquid inlet and the liquid outlet are connected to the existing cooling water circuit of the vehicle, eliminating the need to provide a separate cooling water circuit for the charging and discharging assembly 1, thereby achieving the effects of improving the vehicle integration, reducing the number of parts, and lowering the cost. At the same time, the end of the third water nozzle 17 located outside the first housing 11 can also be provided with a bent portion 171, and the bent portion 171 is bent relative to the first housing 11 to facilitate the connection of the third water nozzle 17 to the vehicle's overall cooling water circuit through the bent portion 171.

[0091] In a specific embodiment, such as Figure 4 and Figure 6 As shown, the first housing 11 also has at least one protruding portion 19, and a wiring harness mounting hole 191 can be provided on the protruding portion 19. At least one reinforcing rib 18 can also be provided between the first housing 11 and the first stepped portion 12.

[0092] In this embodiment, the first housing 11 can also have at least one protruding portion 19 provided with a wiring harness mounting hole 191. When the charging and discharging assembly 1 is installed on the transmission assembly, the wiring harness arranged around the transmission assembly can be fixed through the wiring harness mounting hole 191 on the first housing 11, which can further stabilize this part of the wiring harness and prevent the wiring harness from falling off due to jolting during the vehicle's driving process.

[0093] Meanwhile, a plurality of reinforcing ribs 18 may be provided between the first housing 11 and the first stepped portion 12 of the charging and discharging assembly 1 to improve the anti-collision performance of the first housing 11, enhance the protection effect of the first housing 11 on the internal parts of the charging and discharging assembly 1, and prevent damage to the internal parts. The reinforcing ribs 18 may be circumferentially arranged at the connection between the first housing 11 and the first stepped portion 12 to further improve its structural strength and stability.
