[0027] According to a first aspect of this utility model, this utility model provides an integrated power distribution box, such as... Figure 1-3 As shown, it may include:

[0028] The power distribution assembly 1 includes a power distribution housing 11 and a power distribution unit 13. The power distribution unit 13 is disposed in the hollow cavity of the power distribution housing 11, and the side wall of the power distribution housing 11 is provided with a first wire passage hole.

[0029] The charging assembly 2 includes a charging housing 21 and a charging unit 22. The charging housing 21 has a second wire passage hole on its side wall. The charging housing 21 is connected to the side wall of the power distribution housing 11. The second wire passage hole corresponds to the first wire passage hole. The input end of the charging unit 22 is located in the charging housing 21. The output end of the charging unit 22 is connected to the power distribution unit 13 through the second wire passage hole and the first wire passage hole in sequence.

[0030] The existing charging dock 221 and power distribution box are two independent structures, typically located in different positions with a significant distance between them. The charging dock 221 requires a long wire harness 222 to connect to the power distribution box, increasing wiring costs and installation complexity. In this embodiment, the charging housing 21 is directly connected to the outer wall of the power distribution housing 11, integrating the charging dock 221 and the power distribution box into one unit. This reduces the wiring harness between the charging housing 21 and the outside of the power distribution housing 11, thus reducing wiring length and lowering usage costs. The integrated design also facilitates installation. Furthermore, the charging housing 21 is located on the outside of the power distribution housing 11, rather than inside, ensuring that the positions of electronic components such as the power distribution unit 13 within the power distribution housing 11 remain unchanged, without affecting the usability of the power distribution housing 11 itself. By correspondingly configuring the first and second wire-passing holes, when the charging housing 21 is connected to one side wall of the power distribution housing 11, the output end of the charging unit 22 can easily enter the power distribution housing 11 and connect to the power distribution unit 13 through the first and second wire-passing holes. In this embodiment, the input end of the charging unit 22 is connected to an external power supply terminal, such as a charging gun, and the output end of the charging unit 22 is connected to the power distribution unit 13. This allows the external power supply terminal, the charging gun, to supply current to the power distribution unit 13 through the charging unit 22, thereby enabling the power distribution unit 13 to supply power to the battery pack, and thus enabling the battery pack to store electrical energy.

[0031] Preferably, the charging housing 21 and the power distribution housing 11 are rectangular housings.

[0032] Preferably, the second wire hole is coaxial with the first wire hole.

[0033] According to one embodiment of the present invention, such as Figure 1-3 As shown, the charging unit 22 includes a charging base 221 and a wire 222. The charging housing 21 has a card interface on its side. The charging base 221 is connected to the charging housing 21 through the card interface. One end of the wire 222 is connected to the charging base 221, and the other end of the wire 222 is connected to the power distribution unit 13 through the second wire hole and the first wire hole.

[0034] In this embodiment, the charging dock 221 is connected to the side wall of the charging housing 21 via a card interface, which facilitates the connection between the external power supply and the charging dock 221. The charging dock 221 is connected to the power distribution unit 13 via a wire 222, thereby realizing the electrical connection between the charging dock 221 and the power distribution unit 13.

[0035] According to one embodiment of the present invention, such as Figure 1-3 As shown, the charging port of the charging dock 221 extends outside the charging housing 21, and the charging port is provided with a cover 223.

[0036] In this embodiment, the charging interface end of the charging base 221 extends outside the charging housing 21, further facilitating the connection between the external power supply end and the charging base 221. A cover 223 is provided at the charging interface end of the charging base 221, which allows the charging interface end of the charging base 221 to be covered when not charging, preventing the charging interface end from coming into contact with debris and affecting its use.

[0037] According to one embodiment of the present invention, such as Figure 1-3 As shown, there are n card interfaces, each card interface is connected to a charging dock 221, and each charging dock 221 is connected to m wires 222, where n and m are natural numbers, n≥1, m≥n. The number of second wire holes is equal to or greater than the number of wires 222, and the number of first wire holes is the same as the number of second wire holes.

[0038] In this embodiment, multiple card interfaces can be configured according to usage requirements, so that the charging dock 221 can be connected to the charging housing 21 to meet the required quantity.

[0039] According to one embodiment of the present invention, such as Figure 1-3 As shown, there are two card interfaces, each card interface is connected to a charging dock 221, each charging dock 221 is connected to two wires 222, there are four second wire holes, there are four first wire holes, and each wire 222 is connected to the power distribution unit 13 through one second wire hole and one first wire hole respectively.

[0040] In this embodiment, when there are two charging docks 221, there are four second wire holes and four first wire holes. Each wire 222 passes through one second wire hole and one first wire hole respectively, so as to avoid mutual interference between the wires 222 and facilitate the identification of each wire 222.

[0041] According to one embodiment of the present invention, such as Figure 1-3 As shown, the power distribution housing 11 has a first connecting part 14 on its exterior.

[0042] In this embodiment, the first connecting part 14 facilitates the installation of the power distribution housing 11 on equipment such as vehicles or other devices that require the installation of an integrated power distribution box. When the power distribution housing 11 is installed, the charging housing 21 is also installed together, so there is no need to install the charging housing 21 separately.

[0043] Preferably, the charging housing 21 is provided with a second connecting part 23 on the outside, which further improves the installation stability of the integrated power distribution box.

[0044] According to one embodiment of the present invention, such as Figure 2-3 As shown, the card interface corresponds to the first wire hole.

[0045] In this embodiment, by aligning the card interface with the first wire hole, the thread length of the wire 222 between the charging base 221 and the second wire hole is minimized, thereby reducing the length of the wire 222.

[0046] According to one embodiment of the present invention, such as Figure 2-3 As shown, assembly component 3 includes a connecting shaft, a first connecting sleeve, and a second connecting sleeve. One end of the connecting shaft extends into the power distribution housing 11 through the first wire hole and connects to the first connecting sleeve. The other end of the connecting shaft extends into the charging housing 21 through the second wire hole and connects to the second connecting sleeve. The connecting shaft has a hollow channel, and the charging unit 22 extends into the power distribution housing 11 through the hollow channel and connects to the power distribution unit 13.

[0047] In this embodiment, the first connecting sleeve connects and fixes the connecting shaft to the power distribution housing 11, and the second connecting sleeve connects and fixes the connecting shaft to the charging housing 21. That is, one end of the connecting shaft is connected to the power distribution housing 11, and the other end of the connecting shaft is connected to the charging housing 21, so that the power distribution housing 11 and the charging housing 21 are integrated into one unit.

[0048] Preferably, after the first connecting sleeve is connected to the connecting shaft, the first connecting sleeve fits against the wall of the power distribution housing 11 to ensure the airtightness inside the power distribution housing 11. After the second connecting sleeve is connected to the connecting shaft, the second connecting sleeve fits against the wall of the charging housing 21 to ensure the airtightness inside the charging housing 21.

[0049] Preferably, assembly component 3 is a gland connector, which connects the charging housing 21 and the power distribution housing 11 into one unit.

[0050] According to one embodiment of the present invention, such as Figure 1-3 As shown, the side wall of the power distribution housing 11 connected to the charging housing 21 is an L-shaped mounting surface 12.

[0051] In this embodiment, based on the side wall shape of the charging housing 11, the side wall of the power distribution housing 11 connected to the charging housing 21 is configured as an L-shaped assembly surface 12. The L-shaped assembly surface 12 is adapted to the side wall shape of the charging housing 21, so that the integration effect between the charging housing 21 and the power distribution housing 11 is better.

[0052] According to one embodiment of the present invention, such as Figure 2-3 As shown, the power distribution unit 13 includes a conductor shunt 131, a charging relay 132, an MSD module 133, a discharge relay 134, a battery pack connector 135, an HVM module 136, a power distribution connector 137, a current sensor 138, and a BMS module 139.

[0053] In this embodiment, the charging dock 221 is connected to the wire shunt 131, the wire shunt 131 is connected to the charging relay 132, the charging relay 132 is connected to the current sensor 138, the current sensor 138 is connected to the battery pack connector 135, the battery pack connector 135 is connected to the battery pack, the HVM module 136 is connected to the charging relay 132, and at the same time, the HVM module 136 is also connected to the current sensor 138, the power distribution connector 137 is connected to the battery pack, and the BMS module 139 is connected to the HVM module 136.

[0054] During charging, the charging base 221 receives electrical energy from the external charging gun. The BMS (Battery Management System) module 139 sends a command to close the charging relay 132. Electrical energy flows from the charging base 221 through the wire shunt 131 to the charging relay 132 and the current sensor 138, and then to the battery pack connector 135. The battery pack connector 135 is connected to the battery pack via a wiring harness, thus charging the battery pack. When the battery pack discharges, the power distribution connector 137 supplies current to the current sensor 138, which in turn supplies current to the discharge relay 134. The discharge relay 134 connects to the battery pack connector 135 and to each power distribution connector 137 connected to the wire shunt 131, the current sensor 138, the relay, and the power distribution housing 11. The current is then output to each load via the wiring harness. Regardless of whether charging or discharging, the HVM module 136 (High Voltage Module) samples and processes the current and voltage that need to be sampled to ensure that the power supply can be disconnected in time in case of abnormal overload or short circuit. The MSD (Manual Service Disconnect) module 133 is used to quickly disconnect high-voltage circuits during emergencies or maintenance, ensuring personnel safety and normal equipment operation.

[0055] Preferably, the conductor shunt 131 is a copper busbar.

[0056] According to a second aspect of the present invention, the present invention provides a vehicle including the integrated power distribution box as described above.

[0057] In this embodiment, a vehicle with the aforementioned integrated power distribution box is provided. Specifically, when the integrated power distribution box is installed on the vehicle, it is placed near the charging opening on the vehicle. The charging opening on the vehicle is existing technology. The power distribution housing 11 is fixed inside the vehicle body via the first connecting part 14, and the charging housing 21 is also fixed inside the vehicle body. The input end of the charging housing 21 in the integrated power distribution box is located on the charging opening on the vehicle. When charging the vehicle, the charging gun is inserted into the charging socket 221 on the charging housing 21 through the charging opening on the vehicle, thereby enabling the power distribution box to supply power to the battery pack on the vehicle.
