[0040] The high-voltage integrated module, chassis, and vehicle provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0041] Optionally, such as Figures 1 to 5 As shown, this application embodiment proposes a high-voltage integrated module 10, including a connecting part 12; the connecting part 12 is adapted to be connected to a vehicle frame 20 so that the high-voltage integrated module 10 constitutes at least part of the chassis.

[0042] In this embodiment, the high-voltage integrated module 10 is connected to the frame 20 via the connecting part 12, so that the high-voltage integrated module 10 constitutes at least part of the chassis. In this way, by integrating the high-voltage integrated module 10 with the frame 20, an efficient and compact structure is formed, thereby improving the integration degree of the two and reducing the space occupied by the high-voltage integrated module 10, thus facilitating the overall structural layout of the vehicle.

[0043] Optionally, it also includes a main body 11, with a connecting portion 12 disposed on at least a portion of the circumferential edge of the main body 11, and the main body 11 is adapted to be installed on the bottom of the vehicle.

[0044] In existing technologies, most hybrid vehicles also place the high-voltage charging and distribution system in the luggage compartment, which reduces the volume of the luggage compartment.

[0045] In this embodiment, the connection portion 12 of the high-voltage integrated module 10 is disposed on at least a portion of the circumferential edge of the main body portion 11, which is then mounted on the bottom of the vehicle. This facilitates the use of space at the bottom of the vehicle, avoids occupying space in the luggage compartment, and thus improves space utilization.

[0046] Furthermore, the high-voltage integrated module 10 is located outside the luggage compartment, saving space for pipelines to pass through the compartment, simplifying the pipeline layout, and saving costs. At the same time, compared with the conventional luggage compartment layout, the high-voltage integrated module 10 of this application is farther away from the rear anti-collision beam, reducing the risk of collision and improving the safety performance of the high-voltage integrated module 10.

[0047] Optionally, such as Figure 2 and Figure 3 As shown, the main body 11 includes a housing 111 and a power assembly 112; the housing 111 has a receiving cavity, the power assembly 112 is disposed in the receiving cavity, and the power assembly 112 is used to control the power distribution of the vehicle; the connecting part 12 is disposed on at least a portion of the circumferential edge of the housing 111.

[0048] In this embodiment, the power assembly 112 is disposed within the receiving cavity, and the power assembly 112 controls the vehicle's power distribution; the connecting portion 12 is disposed on at least a portion of the circumferential edge of the housing 111. Thus, the vehicle's power distribution can be controlled via the power assembly 112, simplifying the structure of the vehicle's power distribution system and improving the efficiency and reliability of system control.

[0049] Optionally, such as Figure 1 and Figure 3 As shown, the connecting part 12 includes a first sub-connecting part 121; the first sub-connecting part 121 is disposed on at least one side of the housing 111 along the first direction X, and the first sub-connecting part 121 is adapted to connect with the crossbeam 23 in the frame 20.

[0050] It should be noted that, as Figure 1As shown, the first direction X is the length direction of the vehicle.

[0051] In this embodiment, by providing a first sub-connecting portion 121 on at least one side of the housing 111 along the first direction X, the first sub-connecting portion 121 is connected to the crossbeam 23 in the frame 20. In this way, the connection between the housing 111 and the frame 20 is realized by connecting the first sub-connecting portion 121 to the crossbeam 23 in the frame 20.

[0052] Specifically, the first sub-connecting part 121 can be configured as a lifting lug structure, with multiple first mounting holes on the lifting lug structure and corresponding second mounting holes on the crossbeam 23. Bolts pass through the first and second mounting holes and connect with nuts, thereby achieving a connection between the high-voltage integrated module 10 and the frame 20, ensuring a secure and reliable connection. Furthermore, the first sub-connecting part 121 and the crossbeam 23 can also be welded together; however, this embodiment does not impose limitations on this.

[0053] In some embodiments, the first sub-connecting portion 121 may be provided on either side of the housing 111 along the length direction of the vehicle, or the first sub-connecting portion 121 may be provided on both sides of the housing 111 along the length direction of the vehicle.

[0054] Optionally, there are two first sub-connecting parts 121; the two first sub-connecting parts 121 are respectively located on both sides of the main body 11 along the first direction X, and the first sub-connecting parts 121 are respectively adapted to connect with the corresponding crossbeams 23.

[0055] In this embodiment, two first sub-connecting portions 121 are provided; the two first sub-connecting portions 121 are respectively provided on both sides of the main body 11 along the first direction X, and the first sub-connecting portions 121 are respectively adapted to connect with the corresponding crossbeams 23. In this way, a stable connection between the high-voltage integrated module 10 and the frame 20 along the first direction X is achieved, the torsional stiffness of the frame 20 is improved, and the overall stability and safety of the frame 20 are guaranteed.

[0056] Optionally, such as Figure 3 As shown, the connecting portion 12 also includes a second sub-connecting portion 122; the second sub-connecting portion 122 is disposed on at least one side of the housing 111 along the second direction Y, and the second sub-connecting portion 122 is adapted to connect with the longitudinal beam 24 in the frame 20.

[0057] It should be noted that, as Figure 1 As shown, the second direction Y is the width direction of the vehicle.

[0058] In this embodiment, the second sub-connecting portion 122 is disposed on at least one side of the housing 111 along the second direction Y, and is connected to the longitudinal beam 24 in the frame 20. Thus, the connection between the housing 111 and the frame 20 is achieved through the connection of the second sub-connecting portion 122 to the longitudinal beam 24 in the frame 20.

[0059] In some embodiments, the second sub-connection portion 122 can be configured as a lifting lug structure, with at least one third mounting hole on the lifting lug structure and a corresponding fourth mounting hole on the longitudinal beam 24. Bolts pass through the third and fourth mounting holes and connect with nuts, thereby achieving a connection between the high-voltage integrated module 10 and the frame 20, ensuring a secure and reliable connection. Furthermore, the second sub-connection portion 122 and the longitudinal beam 24 can also be welded together; however, this embodiment does not impose limitations on this.

[0060] In some embodiments, the second sub-connecting portion 122 may be provided on either side of the housing 111 along the width direction of the vehicle, or the second sub-connecting portion 122 may be provided on both sides of the housing 111 along the width direction of the vehicle.

[0061] In some embodiments, a third sub-connection portion may be provided on any side of the housing 111 along the third direction Z. The third sub-connection portion is connected to the longitudinal beam 24 or the transverse beam 23, where the third direction Z is the height direction of the vehicle. In this way, the third sub-connection portion cooperates with the second sub-connection portion 122 and the first sub-connection portion 121 to achieve a firm connection between the high-voltage integrated module 10 and the frame 20.

[0062] Optionally, such as Figure 5 As shown, the housing 111 includes a body and a top cover; the body and the top cover enclose a receiving cavity; a connecting portion 12 is provided at least a portion of the circumferential edge of the body; and the top cover is adapted to cooperate with the frame 20 to form at least a portion of the floor of the vehicle.

[0063] In this embodiment, a receiving cavity is formed by enclosing the body and the top cover; the connecting portion 12 is provided at least part of the circumferential edge of the body, and the top cover cooperates with the frame 20 to form at least part of the vehicle floor. In this way, by utilizing the cooperation between the top cover and the frame 20, the top cover can be used as part of the vehicle floor, thereby improving the integration of the high-voltage integrated module 10 with the vehicle.

[0064] In some embodiments, a sealing ring may be provided at the circumferential edge of the cover to increase the seal between the cover and the vehicle floor.

[0065] Optionally, the main body is provided with a mounting groove, and the upper cover is provided at the opening of the mounting groove to form the receiving cavity.

[0066] In this embodiment, a mounting groove is provided in the main body, and the top cover is placed over the opening of the mounting groove. This facilitates the installation between the main body and the top cover.

[0067] Optionally, such as Figure 1 and Figure 3 As shown, it also includes an electrical connection terminal 13; the electrical connection terminal 13 is disposed in the housing 111, one end of the electrical connection terminal 13 is electrically connected to the power supply assembly 112, and the other end of the electrical connection terminal 13 extends along the first direction X toward a direction away from the body.

[0068] In this embodiment, the electrical connection terminal 13 is disposed in the housing 111, with one end of the electrical connection terminal 13 electrically connected to the power supply assembly 112, and the other end of the electrical connection terminal 13 extending in the first direction X toward a direction away from the main body. This helps to reduce the connection length between the high-voltage integrated module 10 and the vehicle's electrical equipment.

[0069] In some embodiments, the side of the crossbeam 23 facing the front end 21 is also provided with structural components such as a battery pack and a powertrain; the frame 20 has a front end 21 and a rear end 22, and the electrical connection end 13 can be provided on the side of the body facing the front end 21. This facilitates electrical connection between the electrical connection end 13 and structural components such as the battery pack and powertrain, thereby shortening the connection length of the wiring.

[0070] In some embodiments, such as Figure 3 As shown, the electrical connection terminal 13 includes an AC output interface, a low-voltage control interface, and a low-voltage output interface; wherein the AC output interface is used to supply power to the sockets in the vehicle, the low-voltage control interface is connected to the vehicle's controller, and the low-voltage output interface is used to supply power to the low-voltage equipment in the vehicle.

[0071] In some embodiments, such as Figure 3 As shown, a DC charging port and an AC charging port are also provided on the left side of the housing 111. The DC charging port is used to connect to a DC charging gun, and the AC charging port is used to connect to an AC charging gun. In addition, the high-voltage integrated module 10 may also include other interfaces, which are not limited in this embodiment.

[0072] Optionally, such as Figure 3 As shown, it also includes a heat exchange device; the heat exchange device is thermally connected to the power supply assembly 112 and is used to exchange heat with the power supply assembly 112.

[0073] In this embodiment, a heat exchange device is thermally connected to the power assembly 112. This heat exchange device effectively improves the heat dissipation efficiency of the power assembly 112 and extends its service life.

[0074] Optionally, such as Figure 3 As shown, a connector 14 is provided in the housing 111, which is connected to the heat exchange device to supply heat exchange medium to the heat exchange device.

[0075] In this embodiment, a connector 14 is provided in the housing 111, which communicates with the heat exchange device to supply heat exchange medium to the heat exchange device. This allows the housing 111 to communicate with the heat exchange device via the connector 14, thereby supplying heat exchange medium to the heat exchange device and achieving heat exchange medium flow and heat exchange.

[0076] Specifically, such as Figure 3 As shown, the connector 14 can be located on one side along the second direction Y, offset from the electrical structure of the electrical connection end 13, to avoid leakage of heat exchange medium affecting the normal operation of the electrical interface.

[0077] In some embodiments, the power assembly 112 is provided with a cooling channel; the cooling channel is connected to the connector 14. In this way, the heat exchange medium can be exchanged with the cooling device through the cooling channel.

[0078] Optionally, the power supply assembly 112 includes at least one of an on-board charger, a high-voltage power distribution unit, and a DC-DC converter.

[0079] In this embodiment, the power supply assembly 112 includes at least one of an on-board charger, a high-voltage power distribution unit, and a DC-DC converter. This allows the power supply assembly 112 to efficiently and safely charge and distribute power to the vehicle, thereby enabling power supply and control of the vehicle.

[0080] Specifically, the on-board charger, high-voltage power distribution unit, and DC-DC converter are all housed within the enclosure. The on-board charger is electrically connected to the high-voltage power distribution unit and to the charging gun. The on-board charger converts the AC power from the charging gun into DC power and delivers it to the high-voltage power distribution unit. The high-voltage power distribution unit is electrically connected to the DC-DC converter and distributes the DC power to the DC-DC converter. The DC-DC converter is electrically connected to the vehicle's electrical equipment and supplies power to the vehicle's electrical equipment.

[0081] Optionally, such as Figure 1 As shown, this application embodiment proposes a chassis, including the high-voltage integrated module 10 and the frame 20 of the above embodiment; the connecting part 12 is connected to the frame 20 to form at least part of the chassis.

[0082] In this embodiment, the high-voltage integrated module 10 is connected to the vehicle frame 20 via the connection portion 12, so that the high-voltage integrated module 10 constitutes at least a part of the chassis. This integration of the high-voltage integrated module 10 with the frame 20 creates an efficient and compact structure, improving the integration level and reducing the space occupied by the high-voltage integrated module 10, thus facilitating the overall structural layout of the vehicle.

[0083] Optionally, such as Figure 1 As shown, the frame 20 has a front end 21 and a rear end 22, and the high-voltage integrated module 10 is located on the side of the frame 20 near the rear end 22.

[0084] In this embodiment, the high-voltage integrated module 10 is disposed on the side of the frame 20 near the rear end 22. This allows for the efficient use of the space on the side of the frame 20 near the rear end 22 to achieve a reasonable layout of the high-voltage integrated module 10.

[0085] Optionally, such as Figure 4 The distance from the connecting part 12 near the rear end 22 to the rear end 22 is L1, which satisfies: L1≥400mm.

[0086] In this embodiment, the distance L1 between the connecting portion 12 near the rear end 22 and the rear end 22 is set to be greater than 400mm. This ensures that a certain buffer distance is maintained between the rear end 22 and the high-voltage integrated module 10, providing buffer space for the high-voltage integrated module 10 in the event of a collision at the rear end 22.

[0087] For example, L1 can be set to any value greater than 400mm; such as 400mm, 500mm, 600mm, 700mm, 800mm, 900mm, etc.

[0088] Optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the frame 20 includes two crossbeams 23; the two crossbeams 23 are arranged opposite each other along a first direction X, which is the length direction of the vehicle, and the two crossbeams 23 are respectively connected to the corresponding connecting parts 12.

[0089] In this embodiment, two crossbeams 23 are arranged opposite each other along the length of the vehicle; each crossbeam 23 is connected to a corresponding connecting part 12. In this way, by setting the connection between the two crossbeams 23 and the corresponding connecting parts 12, a stable connection between the high-voltage integrated module 10 and the frame 20 along the width of the vehicle is achieved, which improves the torsional stiffness of the frame 20 and ensures the overall stability and safety of the frame 20.

[0090] Specifically, the connecting part 12 includes two first sub-connecting parts 121, which are respectively located on both sides of the main body 11 along the length direction of the vehicle. One of the two crossbeams 23 is connected to one first sub-connecting part 121, and the other crossbeam 23 is connected to the other first sub-connecting part 121.

[0091] In some embodiments, the two crossbeams 23 and the high-voltage integrated module 10 in this application are positioned where the original rear floor under-beam of the vehicle body was located. This application splits the original rear floor under-beam of the vehicle body into two crossbeams 23 and the high-voltage integrated module 10. In this way, it not only physically replaces the original vehicle floor under-beam, but also uses the strength of the high-voltage integrated module 10 to increase the torsional stiffness of the frame 20, thereby functionally replacing the rear floor under-beam of the vehicle body.

[0092] In addition, the first sub-connecting part 121 serves as a connecting bridge, ensuring a firm connection between the crossbeam 23 and the main body 11 of the frame 20, and playing a supporting and stabilizing role.

[0093] Optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the frame 20 also includes two longitudinal beams 24; the two longitudinal beams 24 are arranged opposite each other along the second direction Y; the second direction Y is the width direction of the vehicle, and the two longitudinal beams 24 are respectively connected to the corresponding connecting parts 12.

[0094] In this embodiment, two longitudinal beams 24 are arranged opposite each other along the width direction of the vehicle, and each longitudinal beam 24 is connected to a corresponding connecting part 12. In this way, by setting the connection between the two longitudinal beams 24 and the corresponding connecting parts 12, a stable connection between the high-voltage integrated module 10 and the frame 20 along the width direction of the vehicle is achieved, which improves the torsional stiffness of the frame 20 and ensures the overall stability and safety of the frame 20.

[0095] Specifically, the connecting part 12 includes two second sub-connecting parts 122, which are respectively provided on both sides of the main body 11 along the width direction of the vehicle. One of the second sub-connecting parts 122 is connected to one of the longitudinal beams 24, and the other second sub-connecting part 122 is connected to the other longitudinal beam 24.

[0096] In addition, the second sub-connecting part 122 serves as a connecting bridge to ensure a firm connection between the longitudinal beam 24 and the main body 11 of the frame 20, thus providing support and stability.

[0097] Optionally, such as Figure 4As shown, the longitudinal beam 24 is connected to the connecting part 12 at the first mounting point 25. The longitudinal beam 24 is also provided with a second mounting point 26, which is suitable for connecting the motor assembly. Along the length of the vehicle, the distance between the first mounting point 25 and the second mounting point 26 is L2, which satisfies: 0mm≤L2≤300mm.

[0098] In this embodiment, the distance L2 between the first mounting point 25 and the second mounting point 26 is set within a certain range along the length of the vehicle. This helps to reduce the vibration of the motor assembly when it is operating. Furthermore, the distance L2 between the two mounting points can be adjusted arbitrarily between 0mm and 300mm, allowing the high-voltage integrated module 10 to adapt to the installation requirements of different vehicle models and power systems.

[0099] Specifically, such as Figure 4 As shown, because the high voltage integrated module 10 is mounted on the frame 20, the torsional stiffness of the frame 20 at the location of the high voltage integrated module 10 is increased; and because the second mounting point 26 is located near the high voltage integrated module 10, the higher torsional stiffness here helps to reduce the vibration transmitted from the motor assembly to the frame 20.

[0100] For example, L2 can be set to any value such as 0mm, 50mm, 100mm, 150mm, 200mm, 250mm, 300mm, etc., and the range between any two values.

[0101] Optionally, embodiments of this application propose a vehicle including the high-voltage integrated module 10 of the above embodiments; or, including the chassis of the above embodiments.

[0102] In this embodiment, the high-voltage integrated module 10 is connected to the frame 20 via the connecting part 12, so that the high-voltage integrated module 10 constitutes at least part of the chassis. In this way, by integrating the high-voltage integrated module 10 with the frame 20, an efficient and compact structure is formed, thereby improving the integration degree of the two and reducing the space occupied by the high-voltage integrated module 10, thus facilitating the overall structural layout of the vehicle.

[0103] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.
