[0044] With the increasing emphasis on environmental protection, electric vehicles using battery devices as the power source for vehicles are more and more widely used. With the development of the electric vehicle industry, the market competition is becoming more and more fierce, and how to reduce the cost of the vehicle is more and more concerned by those skilled in the art.

[0045] Since the energy source in the electric vehicle is from the battery device, in order to manage the output of the electric energy in the battery device, a power distribution module is usually arranged in the electric vehicle to manage the output of the electric energy. When the arrangement position of the power distribution module and the arrangement position of the charging interface of the vehicle are not on the same side of the vehicle, the wire harness led out from the battery device needs to pass through the power distribution module first and then lead to the charging interface on the other side. At this time, the wire harness is led from one end of the vehicle to the other end of the vehicle, and the wire harness has a repeated arrangement part in the vehicle, which makes the arrangement length of the wire harness longer and requires a higher arrangement space of the whole vehicle, and is easy to interfere with the water pipe, brake pipe and the like of the whole vehicle. In addition, since the wire harness here is a wire harness for transmitting electric energy, the cross-sectional area is large and the price is high, which also makes the cost of the vehicle higher.

[0046] In order to reduce the cost of the vehicle, some embodiments of the present application provide a vehicle, which comprises a vehicle frame, a first connector, a battery device, a power distribution module and a charging interface. The first connector is arranged on the vehicle frame, and the first connector comprises a first connecting part, a second connecting part and a third connecting part. The second connecting part and the third connecting part are both connected to the first connecting part. The battery device is detachably connected to the vehicle frame, and the battery device comprises a second connector which is used to be connected with the first connecting part. The power distribution module is arranged on the vehicle frame and is electrically connected to the second connecting part. The charging interface is arranged on the vehicle frame and is electrically connected to the third connecting part. 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. In the above structure, since the projection of the first connector in the vertical direction is located between the projection of the power distribution module in the vertical direction and the projection of the charging interface in the vertical direction, and the second connecting part in the first connector is connected to the power distribution module and the third connecting part is connected to the charging interface, the wire harness between the second connecting part and the power distribution module and the wire harness between the third connecting part and the charging interface are not easy to be repeatedly arranged, which is beneficial to shorten the use amount of the wire harness, thereby being beneficial to reduce the cost of the vehicle.

[0047] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the vehicle 1000 provided by some embodiments of the present application is shown. The vehicle 1000 can be a fuel automobile, a gas automobile or a new energy automobile, and the new energy automobile can be a pure electric vehicle, a hybrid electric vehicle or a range extended vehicle. The vehicle 1000 is internally provided with a battery device 100, which can be arranged at the bottom, the head or the tail of the vehicle 1000. The battery device 100 can be used for power supply of the vehicle 1000, for example, the battery device 100 can be used as the operating power supply of the vehicle 1000. The vehicle 1000 can further comprise a controller 200 and a motor 300, and the controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the working power demand of the vehicle 1000 during starting, navigation and driving.

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

[0049] Some embodiments of the present application provide a vehicle 1000, which refers to Figure 2 The vehicle 1000 includes a vehicle 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 arranged on the vehicle frame 1, which refers to Figure 3 The first connector 2 includes a first connecting part 21, a second connecting part 22, and a third connecting part 23, and the second connecting part 22 and the third connecting part 23 are both connected to the first connecting part 21. The battery device 100 is detachably connected to the vehicle frame 1, and the battery device 100 includes a second connector 3 for connecting with the first connecting part 21. The power distribution module 4 is arranged on the vehicle frame 1 and electrically connected to the second connecting part 22. The charging interface 5 is arranged on the vehicle frame 1 and electrically connected to the third connecting part 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 vehicle frame 1 can be a frame structure in the vehicle 1000, which can connect the vehicle 1000, carry the vehicle body, and carry the load of the vehicle 1000.

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

[0052] The first connecting part 21, the second connecting part 22, and the third connecting part 23 can be parts in the first connector 2 for electrically connecting with other parts. The first connecting part 21, the second connecting part 22, and the third connecting part 23 are all made of conductive materials, and by connecting the second connecting part 22 and the third connecting part 23 to the first connecting part 21, the current can be transmitted between the first connecting part 21, the second connecting part 22, and the third connecting part 23. Exemplarily, the first connecting part 21, the second connecting part 22, and the third connecting part 23 can be made of copper, copper alloy, aluminum, or aluminum alloy, so that the first connecting part 21, the second connecting part 22, and the third connecting part 23 all have good conductivity.

[0053] The battery device 100 is used as a device for storing electric energy in the vehicle 1000, and needs to be electrically connected with the power distribution module 4 and the charging interface 5. By detachably connecting the battery device 100 to the vehicle frame 1, the battery device 100 can be detached from the vehicle 1000, so that the vehicle 1000 can be timely supplemented with electric energy by replacing the battery device 100, which is advantageous to solve the problem of long charging time of the electric vehicle 1000.

[0054] Exemplarily, the battery device 100 can be provided with a lock shaft 101, and the vehicle frame 1 is provided with a locking device 14. When the locking device 14 is in a locked state, it can be connected to the lock shaft 101 of the battery device 100, so that the battery device 100 is connected to the vehicle frame 1. When the locking device 14 is in an unlocked state, it can be disconnected from the lock shaft 101 of the battery device 100, so that the battery device 100 can be detached from the vehicle frame 1.

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

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

[0057] The power distribution module 4 is arranged on the vehicle frame 1 and electrically connected with the second connecting portion 22. The power distribution module 4 can be fixed on the vehicle frame 1, so that the power distribution module 4 can be carried by the vehicle frame 1, and the power distribution module 4 is connected with the second connecting portion 22 through the wire harness 6, so that the electric energy of the battery device 100 can be transmitted to the power distribution module 4 through the second connecting portion 22.

[0058] The charging interface 5 is arranged on the vehicle frame 1 and electrically connected with the third connecting portion 23. The charging interface 5 can be fixed on the vehicle frame 1, so that the charging interface 5 can be carried by the vehicle frame 1 and the vehicle frame 1 can withstand the plugging force of the charging interface 5. The charging interface 5 is connected with the third connecting portion 23 through the wire harness 6, so that the electric energy input by the charging interface 5 can be transmitted to the battery device 100 through the third connecting portion 23.

[0059] The projection of the first connector 2 in the vertical direction is 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, which should be understood in a broad sense, as long as the projection of the first connector 2 in the vertical direction is in the area 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. Exemplarily, referring to Figure 4 It can be that the projection of the first connector 2 in the vertical direction is on the line 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; referring to Figure 5 It can also be that the projection of the first connector 2 in the vertical direction is not on the line 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, but is in the area 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 along the front-rear direction of the vehicle 1000.

[0060] In the above structure, since the projection of the first connector 2 in the vertical direction is 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, and the second connecting portion 22 in the first connector 2 is connected to the power distribution module 4 and the third connecting portion 23 is connected to the charging interface 5, the wiring harness 6 between the second connecting portion 22 and the power distribution module 4 and the wiring harness 6 between the third connecting portion 23 and the charging interface 5 are not prone to repeated arrangement, which is conducive to reducing the use amount of the wiring harness 6, thereby facilitating the reduction of the cost of the vehicle 1000.

[0061] In some embodiments, referring to Figure 6 and Figure 7 , the second connector 3 is plug-in matched with the first connecting portion 21.

[0062] The plug-in matching of the second connector 3 with the first connecting portion 21 can be that one of the second connector 3 and the first connecting portion 21 is provided with a socket 211, and the other is provided with a plug-in structure 321, and the plug-in structure 321 is plug-in matched with the socket 211, so that the second connector 3 and the first connecting portion 21 can be connected through plug-in.

[0063] Through the plug-in matching of the second connector 3 with the first connecting portion 21, the second connector 3 and the first connecting portion 21 can be connected with each other through plug-in, so that the second connector 3 and the first connector 2 are convenient to disassemble, which is conducive to improving the convenience of replacing the battery device 100.

[0064] In some embodiments, referring to Figure 3 , Figure 8 and Figure 9 , the first connector 2 further comprises a first seat body 24 connected with the vehicle 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 seat body 24.

[0065] The first seat body 24 can be a main body structure on the first connector 2, which can serve as a seat structure for bearing the load of the first connecting part 21, the second connecting part 22, the third connecting part 23 and other parts on the first connector 2, and is connected with the vehicle frame 1. For example, at least part of the first connecting part 21, the second connecting part 22 and the third connecting part 23 are located in the first seat body 24, so that the first connecting part 21, the second connecting part 22 and the third connecting part 23 can be in the protective enclosure of the first seat body 24, which is conducive to improving the reliability of the first connector 2.

[0066] For example, the first seat body 24 can be made of an insulating material such as plastic, so that the first seat body 24 has good insulation performance and protection ability.

[0067] In some embodiments, continuing to refer to Figure 3 , the first seat body 24 further comprises a support 241 and a cover 242, the support 241 is formed with a cavity 2411 having an opening and is connected with the vehicle frame 1, the second connecting part 22 and the third connecting part 23 are arranged in the cavity 2411, and the cover 242 is detachably covered on the opening.

[0068] The support 241 can be a main body structure in the first seat body 24, which is connected with the vehicle frame 1 and can transmit the load received by the first connector 2 to the vehicle 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 seat body 24.

[0069] For example, continuing to refer to Figure 9 , the support 241 can be connected to the vehicle frame 1 by connecting bolts, so that the first connector 2 can be conveniently connected to the vehicle frame.

[0070] The cavity 2411 can be a hollow structure arranged in the support 241, which is used to provide space for arranging the second connecting part 22 and the third connecting part 23 in the support 241. The opening of the cavity 2411 can be a passage that can communicate the cavity 2411 with the outside, so that the worker 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 maintain 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 body 24 for plugging the opening. By sealingly covering the opening with the cover 242, the cover 242 can separate the cavity 2411 from the outside, reducing the possibility of rain, dust and other things from the outside entering the cavity 2411, which is conducive to prolonging the service life of the second connecting part 22 and the third connecting part 23.
