A vehicle. A first connector (2) in the vehicle is arranged on a frame (1), and a second connection portion (22) and a third connection portion (23) of the first connector (2) are both connected to a first connection portion (21). A battery device comprises a second connector (3), the second connector (3) being configured to be connected to the first connection portion (21). A power distribution module (4) is arranged on the frame (1) and is electrically connected to the second connection portion (22). A charging interface (5) is arranged on the frame (1) and is electrically connected to the third connection portion (23). The projection of the first connector (2) is located between the projection of the power distribution module (4) and the projection of the charging interface (5). Since the projection of the first connector (2) in the vertical direction is located between the projection of the power distribution module (4) in the vertical direction and the projection of the charging interface (5) in the vertical direction, the second connection portion (22) of the first connector (2) is connected to the power distribution module (4), and the third connection portion (23) is connected to the charging interface (5), a wiring harness between the second connection portion (22) and the power distribution module (4) and a wiring harness between the third connection portion (23) and the charging interface (5) are less prone to overlapping arrangement, which is conducive to shortening the length of wiring harnesses used, thereby being conducive to reducing the costs of the vehicle.

A type of vehicle Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle. Background Technology

[0002] Battery devices have advantages such as high specific energy and high power density, and are widely used in electronic devices and transportation vehicles, such as mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships and power tools.

[0003] With the development of the electric vehicle industry, market competition is becoming increasingly fierce, and how to reduce vehicle costs is attracting more and more attention from those skilled in the art. Summary of the Invention

[0004] In view of the above problems, this application provides a vehicle with a lower cost.

[0005] In a first aspect, some embodiments of this application provide a vehicle including a frame, a first connector, a battery device, a power distribution module, and a charging interface. The first connector is disposed on the frame and includes a first connecting portion, a second connecting portion, and a third connecting portion, both of which are connected to the first connecting portion. The battery device is detachably connected to the frame and includes a second connector for connecting to the first connecting portion. The power distribution module is disposed on the frame and electrically connected to the second connecting portion. The charging interface is disposed on the frame and electrically connected to the third connecting portion. In the vertical direction, the projection of the first connector is located between the projection of the power distribution module and the projection of the charging interface.

[0006] In the above structure, since the vertical projection of the first connector is located between the vertical projection of the power distribution module and the vertical projection of the charging interface, and the second connecting part of the first connector is connected to the power distribution module and the third connecting part is connected to the charging interface, the wiring harness between the second connecting part and the power distribution module and the wiring harness between the third connecting part and the charging interface are less likely to be repeatedly arranged, which helps to shorten the amount of wiring harness used, thereby helping to reduce the cost of the vehicle.

[0007] According to some embodiments of this application, in the vehicle, the second connector is plugged into the first connecting part. By plugging the second connector into the first connecting part, the second connector and the first connecting part can be connected to each other through plugging. This makes it easy to disassemble the second connector and the first connector, which helps to improve the convenience of replacing the battery device.

[0008] According to some embodiments of the present application, the first connector further includes a first base connected to the vehicle frame, and the first connecting part, the second connecting part and the third connecting part are all connected to the first base. The first base is used to bear the load of other components on the first connector, such as the first connecting part, the second connecting part and the third connecting part.

[0009] According to some embodiments of the present application, the vehicle provided with a first seat also includes a support and a cover. The support forms a cavity with an opening. A second connecting part and a third connecting part are both disposed in the cavity. The cover is detachably closed to the opening, so that the operator can observe the condition of the second connecting part and the third connecting part in the cavity through the opening and can perform maintenance on the second connecting part and the third connecting part in the cavity through the opening.

[0010] According to some embodiments of this application, the vehicle further includes a wiring harness. The support is provided with a first wire outlet hole and a second wire outlet hole communicating with the cavity. The wiring harness connected to the second connecting part extends out of the cavity through the first wire outlet hole, and the wiring harness connected to the third connecting part extends out of the cavity through the second wire outlet hole, so that the wiring harness from the outside can extend into the cavity through the first wire outlet hole and the second wire outlet hole to connect with the second connecting part and the third connecting part.

[0011] According to some embodiments of this application, the vehicle is provided with the first wire outlet facing in opposite directions to the second wire outlet, such that the wire harness passing through the first wire outlet and the wire harness passing through the second wire outlet can extend in opposite directions, so that the wire harness passing through the first wire outlet and the wire harness passing through the second wire outlet can be connected to the power distribution module and the charging interface located on opposite sides of the first connector.

[0012] According to some embodiments of the present application, the vehicle is provided with a sealing assembly in both the first and second wire outlet holes, so that the wire harness passing through the first wire outlet hole can be sealed to the inner wall of the first wire outlet hole, reducing the possibility of rainwater, dust and other external substances entering the first connector from the first wire outlet hole.

[0013] According to some embodiments of this application, the second connector includes a second seat and a fourth connecting part. The fourth connecting part is fixed to the second seat and connected to the first connecting part. The second seat is used to bear the load of other components on the second connector, such as the fourth connecting part.

[0014] According to some embodiments of the present application, the vehicle provided has a first connecting part with a socket and a fourth connecting part with a plug-in structure. The plug-in structure is plugged into the socket, so that the plug-in structure on the second connector can be plugged into or unplugged from the socket of the first connector as the battery device is installed or removed from the vehicle frame.

[0015] According to some embodiments of the present application, one of the first seat and the second seat is provided with a guide structure, and the other is provided with a guide hole. The guide hole extends along the central axis of the insertion hole. The guide structure is inserted into the guide hole. During the process of the second connector being inserted into the first connecting part, the guide structure can cooperate to be inserted into the guide hole to guide the insertion process of the second connector and the first connecting part, so as to reduce the possibility of misalignment between the second connector and the first connecting part during the insertion process.

[0016] According to some embodiments of this application, in a vehicle, at least a portion of a first connecting part extends out of a first seat, and an insertion hole is provided at the portion of the first connecting part extending from the first seat; a second seat is provided with a protective structure, which is wrapped around the first connecting part extending from the first seat. By providing a protective structure on the second seat and wrapping the protective structure around the first connecting part extending from the first seat, the protective structure can cover the first connecting part extending from the first seat from its outer periphery.

[0017] According to some embodiments of this application, in the provided vehicle, the second connecting portion and the third connecting portion are spaced apart and arranged around the outer periphery of the first connecting portion.

[0018] According to some embodiments of this application, the vehicle also includes a relay electrically connected between the charging interface and the third connection portion, enabling the relay to disconnect or connect the electrical connection between the charging interface and the third connection portion, and enabling the relay to control whether the charging interface charges the battery device, thereby facilitating the control of the vehicle's charging process.

[0019] According to some embodiments of the present application, the vehicle provided by the first connector further includes a first signal interface, which is communicatively connected to a relay. The second connector further includes a second signal interface, which is communicatively connected to a battery device. The second signal interface is plugged into the first signal interface, which not only enables the relay and the battery device to communicate through the plugging of the second signal interface into the first signal interface, but also enables the second signal interface and the first signal interface to be connected together with the plugging of the second connector into the first connector.

[0020] According to some embodiments of this application, the vehicle includes a first connecting part including a first positive terminal and a first negative terminal, a second connecting part including a second positive terminal and a second negative terminal, and a third connecting part including a third positive terminal and a third negative terminal. The second positive terminal and the third positive terminal are connected to the first positive terminal, and the second negative terminal and the third negative terminal are connected to the first negative terminal.

[0021] According to some embodiments of this application, the vehicle frame includes a first subframe, a second subframe, and an energy compartment. The battery device is housed in the energy compartment. Along the front-rear direction of the vehicle, the first subframe and the second subframe are respectively connected to both ends of the energy compartment. The power distribution module is disposed on the first subframe, the charging interface is disposed on the second subframe, and the first connector is disposed on the energy compartment.

[0022] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0023] This application provides a vehicle including a frame, a first connector, a battery device, a power distribution module, and a charging interface. The first connector is disposed on the frame and includes a first connecting portion, a second connecting portion, and a third connecting portion, both of which are connected to the first connecting portion. The battery device is detachably connected to the frame and includes a second connector for connecting to the first connecting portion. The power distribution module is disposed on the frame and electrically connected to the second connecting portion. The charging interface is disposed on the frame and electrically connected to the third connecting portion. In the vertical direction, the projection of the first connector lies between the projection of the power distribution module and the projection of the charging interface. In this structure, since the vertical projection of the first connector lies between the vertical projections of the power distribution module and the charging interface, and the second connecting portion of the first connector is connected to the power distribution module, and the third connecting portion is connected to the charging interface, the wiring harness between the second connecting portion and the power distribution module and the wiring harness between the third connecting portion and the charging interface are less likely to be redundantly arranged, which helps to reduce the amount of wiring harness used, thereby reducing the cost of the vehicle.

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.

[0039] It should be noted that, unless otherwise stated, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by those skilled in the art to which the embodiments of this application pertain.

[0040] In the description of the embodiments of this application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0041] Furthermore, technical terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise explicitly defined.

[0042] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] With increasing emphasis on environmental protection, electric vehicles powered by batteries are becoming more and more widely used. As the electric vehicle industry develops and market competition intensifies, reducing vehicle costs is receiving increasing attention from those skilled in the art.

[0045] Since the energy source in electric vehicles comes entirely from battery packs, a power distribution module is typically installed to manage the output of electrical energy from the battery packs. When the location of the power distribution module and the charging port are not on the same side of the vehicle, the wiring harness from the battery pack must first pass through the power distribution module before reaching the charging port on the other side. In this case, the wiring harness will run from the battery pack to one end of the vehicle and then to the other end, resulting in overlapping sections of the wiring harness within the vehicle. This leads to a longer wiring harness length, requiring more space for the overall vehicle layout, and is prone to interference with vehicle water pipes, brake lines, etc. Furthermore, since this wiring harness is for transmitting electrical energy, its cross-sectional area is large, resulting in a higher cost and increasing the overall cost of the vehicle.

[0046] To reduce vehicle costs, some embodiments of this application provide a vehicle including a frame, a first connector, a battery device, a power distribution module, and a charging interface. The first connector is disposed on the frame and includes a first connecting portion, a second connecting portion, and a third connecting portion, both of which are connected to the first connecting portion. The battery device is detachably connected to the frame and includes a second connector for connecting to the first connecting portion. The power distribution module is disposed on the frame and electrically connected to the second connecting portion. The charging interface is disposed on the frame and electrically connected to the third connecting portion. In the vertical direction, the projection of the first connector lies between the projection of the power distribution module and the projection of the charging interface. In this structure, since the vertical projection of the first connector lies between the vertical projections of the power distribution module and the charging interface, and the second connecting portion of the first connector is connected to the power distribution module, and the third connecting portion is connected to the charging interface, the wiring harness between the second connecting portion and the power distribution module and between the third connecting portion and the charging interface are less likely to be redundantly arranged, which helps to reduce the amount of wiring harness used, thereby reducing vehicle costs.

[0047] Please refer to Figure 1, which is a structural schematic diagram of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery device 100 is installed inside the vehicle 1000, and the battery device 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery device 100 can be used to power the vehicle 1000; for example, the battery device 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during startup, navigation, and driving.

[0048] In some embodiments of this application, the battery device 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0049] Some embodiments of this application provide a vehicle 1000. Referring to FIG2, the vehicle 1000 includes a frame 1, a first connector 2, a battery device 100, a power distribution module 4, and a charging interface 5. The first connector 2 is disposed on the frame 1. Referring to FIG3, the first connector 2 includes a first connecting portion 21, a second connecting portion 22, and a third connecting portion 23. The second connecting portion 22 and the third connecting portion 23 are both connected to the first connecting portion 21. The battery device 100 is detachably connected to the frame 1. The battery device 100 includes a second connector 3 for connecting to the first connecting portion 21. The power distribution module 4 is disposed on the frame 1 and electrically connected to the second connecting portion 22. The charging interface 5 is disposed on the frame 1 and electrically connected to the third connecting portion 23. In the vertical direction, the projection of the first connector 2 is located between the projection of the power distribution module 4 and the projection of the charging interface 5.

[0050] The frame 1 can be the frame structure in the vehicle 1000, which can connect the vehicle 1000 and bear the load of the vehicle body and the load of the vehicle 1000.

[0051] The first connector 2 can be a connection device for electrically connecting the battery device 100 to the charging interface 5 and the power distribution module 4. Exemplarily, the first connector 2 can be used to stably connect the wiring harness 6 connected to the charging interface 5 and the wiring harness 6 connected to the power distribution module 4 to the battery device 100.

[0052] The first connecting portion 21, the second connecting portion 22, and the third connecting portion 23 can be components in the first connector 2 that are electrically connected to other components. All three portions are made of conductive material, and by connecting the second connecting portion 22 and the third connecting portion 23 to the first connecting portion 21, current can be transmitted among them. For example, the first connecting portion 21, the second connecting portion 22, and the third connecting portion 23 can be made of copper, copper alloy, aluminum, or aluminum alloy, giving them good electrical conductivity.

[0053] The battery device 100, as a device for storing electrical energy in the vehicle 1000, needs to be electrically connected to the power distribution module 4 and the charging interface 5. By detachably connecting the battery device 100 to the frame 1, the battery device 100 can be removed from the vehicle 1000, allowing the vehicle 1000 to replenish its electrical energy in a timely manner by replacing the battery device 100, which helps to solve the problem of long charging time for the vehicle 1000.

[0054] For example, the battery device 100 may be provided with a locking shaft 101, and the frame 1 may be provided with a locking device 14. When the locking device 14 is in the locked state, it can be connected to the locking shaft 101 of the battery device 100, so that the battery device 100 is connected to the frame 1. When the locking device 14 is in the unlocked state, it can be disconnected from the locking shaft 101 of the battery device 100, so that the battery device 100 can be removed from the frame 1.

[0055] The second connector 3 can be a connector used in conjunction with the first connector 2. The battery device 100 includes the second connector 3, which means that the second connector 3 is connected to the battery device 100, and serves as a device for connecting the battery device 100 to the first connector 2, so that the battery device 100 can be stably electrically connected to the power distribution module 4 and the charging interface 5.

[0056] The second connector 3 connects to the first connection part 21, so that the battery device 100 is electrically connected to the first connection part 21, and the battery device 100 can transmit electrical energy to the power distribution module 4 through the second connection part 22 of the first connector 2. The charging interface 5 can also transmit electrical energy to the battery device 100 through the third connection part 23 of the first connector 2.

[0057] The power distribution module 4 is mounted on the frame 1 and electrically connected to the second connection part 22. Alternatively, the power distribution module 4 can be fixed on the frame 1 so that the frame 1 can support the power distribution module 4, and the power distribution module 4 can be connected to the second connection part 22 through the wiring harness 6 so that the power of the battery device 100 can be transmitted to the power distribution module 4 through the second connection part 22.

[0058] The charging interface 5 is disposed on the frame 1 and electrically connected to the third connection part 23. Alternatively, the charging interface 5 can be fixed on the frame 1 so that the charging interface 5 can be supported by the frame 1 and the frame 1 can withstand the insertion and extraction force of the charging interface 5. The charging interface 5 is connected to the third connection part 23 through the wiring harness 6 so that the electrical energy input by the charging interface 5 can be transmitted to the battery device 100 through the third connection part 23.

[0059] The vertical projection of the first connector 2 lies between the vertical projections of the power distribution module 4 and the charging interface 5. This should be interpreted broadly, meaning that the vertical projection of the first connector 2 is located within the region between these two projections. For example, referring to Figure 4, the vertical projection of the first connector 2 could be located on the line connecting the vertical projections of the power distribution module 4 and the charging interface 5. Referring to Figure 5, the vertical projection of the first connector 2 could not be located on the line connecting the vertical projections of the power distribution module 4 and the charging interface 5, but rather within the region between these two projections along the longitudinal direction of the vehicle 1000.

[0060] In the above structure, since the vertical projection of the first connector 2 is located between the vertical projection of the power distribution module 4 and the vertical projection of the charging interface 5, and the second connecting part 22 of the first connector 2 is connected to the power distribution module 4 and the third connecting part 23 is connected to the charging interface 5, the wiring harness 6 between the second connecting part 22 and the power distribution module 4 and the wiring harness 6 between the third connecting part 23 and the charging interface 5 are less likely to be repeatedly arranged, which helps to shorten the amount of wiring harness 6 used, thereby helping to reduce the cost of the vehicle 1000.

[0061] In some embodiments, referring to Figures 6 and 7, the second connector 3 is inserted into the first connecting portion 21.

[0062] The second connector 3 can be plugged into the first connecting part 21. One of the second connector 3 and the first connecting part 21 may be provided with a socket 211, and the other is provided with a plug-in structure 321. The plug-in structure 321 is plugged into the socket 211, so that the second connector 3 and the first connecting part 21 can be connected by plugging.

[0063] By inserting the second connector 3 into the first connecting part 21, the second connector 3 and the first connecting part 21 can be connected to each other through insertion, making it easy to disassemble the second connector 3 and the first connector 2, which helps to improve the ease of replacing the battery device 100.

[0064] In some embodiments, referring to Figures 3, 8 and 9, the first connector 2 further includes a first base 24 connected to the frame 1, and the first connecting portion 21, the second connecting portion 22 and the third connecting portion 23 are all connected to the first base 24.

[0065] The first seat 24 can be the main structure on the first connector 2. It can serve as a seat structure to bear the load of other components on the first connector 2, such as the first connecting part 21, the second connecting part 22, and the third connecting part 23, and connect to the frame 1. Exemplarily, at least a portion of the first connecting part 21, the second connecting part 22, and the third connecting part 23 are located in the first seat 24, so that the first connecting part 21, the second connecting part 22, and the third connecting part 23 can be surrounded and protected by the first seat 24, which is beneficial to improving the reliability of the first connector 2.

[0066] For example, the first base 24 can be made of insulating materials such as plastic, so that the first base 24 has good insulation performance and protection capability.

[0067] In some embodiments, continuing to refer to FIG3, the first seat 24 further includes a support 241 and a cover 242. The support 241 forms a cavity 2411 with an opening and is connected to the frame 1. The second connecting portion 22 and the third connecting portion 23 are both disposed in the cavity 2411, and the cover 242 is detachably closed to the opening.

[0068] The support 241 can be the main structure in the first base 24, which is connected to the frame 1 and can transfer the load on the first connector 2 to the frame 1. The first connecting part 21, the second connecting part 22 and the third connecting part 23 are all connected to the support 241, so that the first connecting part 21, the second connecting part 22 and the third connecting part 23 can be firmly connected to the first base 24.

[0069] For example, continuing to refer to FIG9, the support 241 can be connected to the frame 1 by connecting bolts, so that the first connector 2 can be easily connected to the frame.

[0070] The cavity 2411 can be a hollow structure provided in the support 241, which provides space for the second connecting part 22 and the third connecting part 23 to be provided in the support 241. The opening of the cavity 2411 can be a channel that connects the cavity 2411 to the outside, so that the staff can observe the condition of the second connecting part 22 and the third connecting part 23 in the cavity 2411 through the opening and can perform maintenance on the second connecting part 22 and the third connecting part 23 in the cavity 2411 through the opening.

[0071] The cover 242 can be a component in the first seat 24 used to seal the opening. By sealing the opening with the cover 242, the cover 242 can separate the cavity 2411 from the outside, reducing the possibility of rainwater, dust and other external substances entering the cavity 2411, which helps to extend the service life of the second connecting part 22 and the third connecting part 23.

[0072] By detachably covering the opening with the cover 242, the cover 242 can be easily removed from the opening, which improves the ease of maintenance of the first connector 2. For example, the cover 242 can be connected to the support 241 and cover the opening with connecting screws.

[0073] In some embodiments, the cover 242 is provided with a slot, and the support 241 is provided with a protrusion near the opening. The protrusion is engaged with the slot to connect the cover 242 and the support 241, which not only allows the cover 242 to be stably closed to the opening, but also makes it easy to disassemble the cover 242 from the opening.

[0074] In some embodiments, the vehicle 1000 further includes a wiring harness 6, and the support 241 is provided with a first wire outlet hole 2412 and a second wire outlet hole 2413 communicating with the cavity 2411. The wiring harness 6 connected to the second connecting part 22 extends out of the cavity 2411 through the first wire outlet hole 2412, and the wiring harness 6 connected to the third connecting part 23 extends out of the cavity 2411 through the second wire outlet hole 2413.

[0075] The wiring harness 6 can refer to the wiring harness 6 that connects the first connector 2 to the power distribution module 4 and the charging interface 5, and is used to make the first connector 2 electrically connected to the power distribution module 4 and the charging interface 5.

[0076] The first cable exit hole 2412 and the second cable exit hole 2413 can be hole-like structures provided on the support 241, which are used to pass through the wire harness 6. Both the first cable exit hole 2412 and the second cable exit hole 2413 communicate the cavity 2411 with the outside, so that the wire harness 6 from the outside can extend into the cavity 2411 through the first cable exit hole 2412 and the second cable exit hole 2413, so as to connect with the second connecting part 22 and the third connecting part 23.

[0077] By allowing the wire harness 6 connected to the second connection part 22 to extend out of the cavity 2411 through the first outlet hole 2412, the second connection part 22 can be connected to the power distribution module 4 via the wire harness 6 passing through the first outlet hole 2412. By allowing the wire harness 6 connected to the third connection part 23 to extend out of the cavity 2411 through the second outlet hole 2413, the third connection part 23 can be connected to the charging interface 5 via the wire harness 6 passing through the second outlet hole 2413.

[0078] In some embodiments, the first cable outlet 2412 is disposed toward the power distribution module 4, and the second cable outlet 2413 is disposed toward the charging interface 5.

[0079] By aligning the first outlet hole 2412 toward the power distribution module 4, the wire harness 6 extending from the first outlet hole 2412 can extend toward the power distribution module 4 with fewer bends, which helps to reduce the length of the wire harness 6. By aligning the second outlet hole 2413 toward the charging interface 5, the wire harness 6 extending from the second outlet hole 2413 can extend toward the charging interface 5 with fewer bends, which also helps to reduce the length of the wire harness 6.

[0080] In some embodiments, the orientation of the first outlet hole 2412 and the orientation of the second outlet hole 2413 are opposite.

[0081] By setting the orientation of the first outlet hole 2412 and the second outlet hole 2413 to be opposite, the wire harness 6 passing through the first outlet hole 2412 and the wire harness 6 passing through the second outlet hole 2413 can extend in opposite directions, so that the wire harness 6 passing through the first outlet hole 2412 and the wire harness 6 passing through the second outlet hole 2413 can be connected to the power distribution module 4 and the charging interface 5 located on opposite sides of the first connector 2.

[0082] In some embodiments, the orientation of the first cable outlet 2412 is arranged along the front-rear direction of the vehicle 1000, and the orientation of the second cable outlet 2413 is arranged along the front-rear direction of the vehicle 1000.

[0083] By setting the orientation of the first outlet hole 2412 and the orientation of the second outlet hole 2413 along the front-rear direction of the vehicle 1000, the power distribution module 4 and the charging interface 5 can be set along the front-rear direction of the vehicle 1000, making it convenient to arrange the power distribution module 4 and the charging interface 5 in the vehicle 1000.

[0084] In some embodiments, a sealing assembly 25 is provided in both the first wire outlet hole 2412 and the second wire outlet hole 2413.

[0085] The sealing assembly 25 can be used to connect the wire harness 6 to the inner wall of the outlet hole and seal the gap between the wire harness 6 and the inner wall of the outlet hole. By providing the sealing assembly 25 in the first outlet hole 2412, the wire harness 6 passing through the first outlet hole 2412 can be sealed to the inner wall of the first outlet hole 2412, reducing the possibility of rainwater, dust, etc. from the outside entering the first connector 2 through the first outlet hole 2412. By providing the sealing assembly 25 in the second outlet hole 2413, the wire harness 6 passing through the second outlet hole 2413 can be sealed to the inner wall of the second outlet hole 2413, reducing the possibility of rainwater, dust, etc. from the outside entering the first connector 2 through the second outlet hole 2413.

[0086] For example, the sealing assembly 25 may include a crimping sleeve, a washer, a sealing body, and a tail cover. The crimping sleeve is fitted around the outer periphery of the wire harness 6. The sealing body is wrapped around the outside of the wire harness 6 and fills the space between the wire harness 6 and the inner wall of the outlet hole. The washer is sandwiched between the crimping sleeve and the sealing body. The tail cover fitted around the wire harness 6 is connected to the support 241 and presses the sealing body against the washer.

[0087] In some embodiments, referring to FIG10, the second connector 3 includes a second base 31 and a fourth connecting portion 32, the fourth connecting portion 32 being fixed to the second base 31 and connected to the first connecting portion 21.

[0088] The second seat 31 can be the main structure on the second connector 3, serving as a seat structure to bear the load of other components on the second connector 3, such as the fourth connecting part 32. For example, at least a portion of the fourth connecting part 32 is located within the second seat 31, allowing the fourth connecting part 32 to be surrounded and protected by the second seat 31, which helps improve the reliability of the second connector 3.

[0089] For example, the second base 31 can be made of insulating materials such as plastic, so that the second base 31 has good insulation performance and protection capability.

[0090] The fourth connecting part 32 can be a component in the second connector 3 that is electrically connected to other components. The fourth connecting part 32 is made of conductive material, and by fixing the fourth connecting part 32 to the second base 31, when the second connector 3 is inserted into the first connecting part 21, the fourth connecting part 32 is connected to the first connecting part 21.

[0091] For example, the fourth connection portion 32 can be made of materials such as copper, copper alloy, aluminum or aluminum alloy, so that the fourth connection portion 32 has good electrical conductivity.

[0092] In some embodiments, the first connecting part 21 is provided with a socket 211, and the fourth connecting part 32 is provided with a plug-in structure 321, which is plugged into the socket 211.

[0093] By providing a socket 211 on the first connecting part 21 and a plug-in structure 321 on the fourth connecting part 32, the plug-in structure 321 on the second connector 3 can be plugged into or unplugged from the socket 211 of the first connector 2 as the battery device 100 is installed or removed from the vehicle frame 1.

[0094] For example, the end of the plug-in structure 321 facing the socket 211 is provided with a tapered structure, so that the plug-in structure 321 can be smoothly inserted into the socket 211.

[0095] In some embodiments, one of the first seat 24 and the second seat 31 is provided with a guide structure 243, and the other is provided with a guide hole 311. The guide hole 311 extends along the central axis of the insertion hole 211, and the guide structure 243 is inserted into the guide hole 311.

[0096] The guide structure 243 can be a protruding structure, and the guide hole 311 can be a hole-like structure. During the process of the second connector 3 being inserted into the first connecting part 21, the guide structure 243 can cooperate to be inserted into the guide hole 311 to guide the insertion process of the second connector 3 and the first connecting part 21, so as to reduce the possibility of misalignment between the second connector 3 and the first connecting part 21 during the insertion process.

[0097] By extending the guide hole 311 along the central axis of the insertion hole 211, the guide structure 243 can guide the insertion structure 321 into the insertion hole 211 during the insertion process of the guide hole 311, thereby reducing the possibility of misalignment of the insertion structure 321 during the insertion process of the insertion hole 211.

[0098] For example, the second seat 31 may have a guide hole 311 on the side facing the support 241, and the support 241 may have a guide structure 243 protruding on the side facing the second seat 31.

[0099] In other embodiments, a guide structure 243 protrudes from the side of the second seat 31 facing the support 241, and a guide hole 311 is provided on the side of the support 241 facing the second seat 31.

[0100] In some embodiments, at least a portion of the first connecting portion 21 extends out of the first base 24, and the insertion hole 211 is provided at the portion of the first connecting portion 21 that extends out of the first base 24; the second base 31 is provided with a protective structure 312, which is arranged around the first connecting portion 21 that extends out of the first base 24.

[0101] By extending at least a portion of the first connecting part 21 out of the first base 24, the second connector 3 can be easily connected to the first connecting part 21. By providing a socket 211 at the portion of the first connecting part 21 extending from the first base 24, the insertion structure 321 on the second connector 3 can be easily inserted into the socket 211 during connection to the first connecting part 21, allowing the fourth connecting part 32 to be easily connected to the first connecting part 21 via insertion.

[0102] The protective structure 312 can be a structure for protecting the portion of the first connecting part 21 that extends from the surface of the first seat 24 toward the second seat 31. By providing the protective structure 312 on the second seat 31 and surrounding the first connecting part 21 that extends from the first seat 24, the protective structure 312 can cover the first connecting part 21 that extends from the first seat 24 from its outer periphery.

[0103] For example, the protective structure 312 is spaced around the outer periphery of the plug-in structure 321, such that when the plug-in structure 321 is plugged into the socket 211, the structure of the wall of the fourth connecting part 32 can be located in the space between the protective structure 312 and the plug-in structure 321.

[0104] In some embodiments, the second connecting portion 22 and the third connecting portion 23 are spaced around the outer periphery of the first connecting portion 21.

[0105] The second connecting portion 22 and the third connecting portion 23 are spaced apart around the outer periphery of the first connecting portion 21. This can mean that the second connecting portion 22 and the third connecting portion 23 are spaced apart around the outer periphery of the first connecting portion 21.

[0106] For example, the second connecting portion 22 and the third connecting portion 23 are arranged at equal intervals around the first connecting portion 21 on the outer periphery of the first connecting portion 21, so that the device arrangement in the second connector 3 is convenient and the distribution is more reasonable.

[0107] In some embodiments, the vehicle 1000 further includes a relay 7, which is electrically connected between the charging interface 5 and the third connection portion 23.

[0108] The relay 7 is electrically connected between the charging interface 5 and the third connection part 23. This means that the relay 7 is connected to the wiring harness 6 between the charging interface 5 and the third connection part 23, so that the relay 7 can disconnect or connect the electrical connection between the charging interface 5 and the third connection part 23, and the relay 7 can control whether the charging interface 5 charges the battery device 100, so as to facilitate the control of the charging process of the vehicle 1000.

[0109] In some embodiments, the first connector 2 further includes a first signal interface 26, which is communicatively connected to the relay 7, and the second connector 3 further includes a second signal interface 33, which is communicatively connected to the battery device 100 and is plugged into the first signal interface 26.

[0110] The first signal interface 26 can be an interface on the first connector 2 for transmitting communication signals, and the second signal interface 33 can be an interface on the second connector 3 for transmitting communication signals. By connecting the second signal interface 33 to the first signal interface 26, the second connector 3 can achieve a communication connection by connecting to the first connector 2.

[0111] The first signal interface 26 is communicatively connected to the relay 7, which means that the first signal interface 26 and the relay 7 are connected via a signal line. The second signal interface 33 is communicatively connected to the battery device 100, which means that the second signal interface 33 and the battery device 100 are connected via a signal line.

[0112] The second signal interface 33 is plugged into the first signal interface 26, which not only enables the relay 7 and the battery device 100 to communicate through the second signal interface 33 and the first signal interface 26, but also enables the second signal interface 33 and the first signal interface 26 to be connected together with the second connector 3 and the first connector 2.

[0113] In some embodiments, the first connection portion 21 includes a first positive terminal 212 and a first negative terminal 213, the second connection portion 22 includes a second positive terminal (not shown) and a second negative terminal (not shown), and the third connection portion 23 includes a third positive terminal (not shown) and a third negative terminal (not shown). The second positive terminal and the third positive terminal are connected to the first positive terminal 212, and the second negative terminal and the third negative terminal are connected to the first negative terminal 213.

[0114] The first positive terminal 212 can be a terminal structure in the first connecting part 21 that can be electrically connected to the positive terminal of the battery device 100, and the first negative terminal 213 can be a terminal structure in the first connecting part 21 that can be electrically connected to the negative terminal of the battery device 100.

[0115] The second positive terminal can be a terminal structure in the second connection part 22 that is electrically connected to the first positive terminal 212, and the second negative terminal can be a terminal structure in the second connection part 22 that is electrically connected to the first negative terminal 213.

[0116] The third positive terminal can be a terminal structure in the third connection part 23 that is electrically connected to the first positive terminal 212, and the third negative terminal can be a terminal structure in the third connection part 23 that is electrically connected to the first negative terminal 213.

[0117] For example, the second positive terminal, the second negative terminal, the third positive terminal, and the third negative terminal can be connection terminals made of materials such as copper, copper alloy, aluminum, or aluminum alloy.

[0118] In some embodiments, the second positive terminal, the second negative terminal, the third positive terminal, and the third negative terminal can be connected to the wire harness 6 by welding.

[0119] In some embodiments, the frame 1 includes a first subframe 11, a second subframe 12, and an energy compartment 13. The battery device 100 is housed in the energy compartment 13. Along the longitudinal direction of the vehicle 1000, the first subframe 11 and the second subframe 12 are respectively connected to the two ends of the energy compartment 13. The power distribution module 4 is disposed on the first subframe 11, the charging interface 5 is disposed on the second subframe 12, and the first connector 2 is disposed on the energy compartment 13.

[0120] The first subframe 11, the second subframe 12, and the energy compartment 13 are different parts of the frame 1. The energy compartment 13 is located in the middle of the frame 1. The first subframe 11 and the second subframe 12 are respectively connected to the two ends of the energy compartment 13 in the front-rear direction of the vehicle 1000. One of the first subframe 11 and the second subframe 12 is the front subframe 1, and the other is the rear subframe 1.

[0121] The energy chamber 13 has a cavity, and the battery device 100 is located in the cavity and detachably connected to the wall of the energy chamber 13, so that the battery device 100 can be detached in the energy chamber 13.

[0122] By setting the power distribution module 4 on the first subframe 11, the charging interface 5 on the second subframe 12, and the first connector 2 on the energy compartment 13, the first connector 2 is positioned between the power distribution module 4 and the charging interface 5. This makes it less likely that the wiring harness 6 between the second connection part 22 and the power distribution module 4 and the wiring harness 6 between the third connection part 23 and the charging interface 5 will be redundantly arranged, which helps to reduce the amount of wiring harness 6 used, thereby helping to reduce the cost of the vehicle 1000.

[0123] Some embodiments of this application provide a vehicle 1000, as shown in Figures 4 and 5. The vehicle 1000 includes a frame 1, a first connector 2, a battery device 100, a power distribution module 4, and a charging interface 5. The frame 1 includes a first subframe 11, a second subframe 12, and an energy compartment 13. Along the front-rear direction of the vehicle 1000, the first subframe 11 and the second subframe 12 are respectively connected to the two ends of the energy compartment 13. The battery device 100 is detachably connected to the energy compartment 13. The power distribution module 4 is disposed on the first subframe 11, the charging interface 5 is disposed on the second subframe 12, and the first connector 2 is disposed on the energy compartment 13 such that the vertical projection of the first connector 2 is located between the vertical projection of the power distribution module 4 and the vertical projection of the charging interface 5. The battery device 100 includes a second connector 3. The first connector 2 includes a first connecting part 21, a second connecting part 22 and a third connecting part 23. The second connecting part 22 and the third connecting part 23 are both connected to the first connecting part 21. The second connecting part 22 is electrically connected to the power distribution module 4, and the third connecting part 23 is electrically connected to the charging interface 5. The second connector 3 is used to connect to the first connecting part 21.

[0124] In the above structure, since the vertical projection of the first connector 2 is located between the vertical projection of the power distribution module 4 and the vertical projection of the charging interface 5, and the second connecting part 22 of the first connector 2 is connected to the power distribution module 4 and the third connecting part 23 is connected to the charging interface 5, the wiring harness 6 between the second connecting part 22 and the power distribution module 4 and the wiring harness 6 between the third connecting part 23 and the charging interface 5 are less likely to be repeatedly arranged, which helps to shorten the amount of wiring harness 6 used, thereby helping to reduce the cost of the vehicle 1000.

[0125] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
