[0031] See also Figure 1 As shown, according to an embodiment of the present utility model, a quick-connect plug structure 1 is provided, comprising: a housing 10 and a plurality of connectors 11 .

[0032] Among them, at least one end of the shell 10 is an open structure, and a plurality of connectors 11 are arranged inside the shell 10. The shell 10 can be arranged outside the shell of the power distribution unit 2 and connected to the power distribution unit 2, and the plurality of connectors 11 are correspondingly connected to the internal components of the power distribution unit 2.

[0033] like Figure 2 As shown, when the battery pack 3 of the vehicle is installed, the multiple connectors 11 of the quick-connect plug structure 1 are docked with the connection terminals 30 of the battery pack 3, thereby completing the electrical connection between the power distribution unit 2 and the battery pack 3.

[0034] In one embodiment, the housing 10 of the quick-connect plug structure 1 has two opposite openings, one of which is used to communicate with the interior of the power distribution unit 2 , and the other opening is used to expose the plurality of connectors 11 .

[0035] In order to achieve quick connection between the power distribution unit 2 and the battery pack 3 , the arrangement of the multiple connectors 11 of the quick-connect plug structure 1 corresponds to the arrangement of the connection terminals 30 of the battery pack 3 .

[0036] In one embodiment, the multiple connectors 11 of the quick-connect plug structure 1 include a high-voltage terminal 110 and a low-voltage terminal 111. One end of the high-voltage terminal 110 is used to connect the high-voltage device of the power distribution unit 2, and one end of the low-voltage terminal 111 is used to connect the signal device of the power distribution unit 2.

[0037] In this embodiment, the quick-connect plug structure 1 connects the high-voltage terminal 110 and the low-voltage terminal 111, so that when the battery pack 3 is connected to the power distribution unit 2, there is no need to connect the power supply and the signal separately, thereby improving the connection efficiency.

[0038] In one embodiment, in order to prevent the high voltage in the high voltage terminal 110 from interfering with the low voltage terminal 111 , a shielding layer is provided between the high voltage terminal 110 and the low voltage terminal 111 .

[0039] Optionally, the shielding layer is made of metal.

[0040] In one embodiment, a buffer member 12 is provided on the side of the quick-connect plug structure 1 facing the battery pack 3. When the power distribution unit 2 and the battery pack 3 are connected through the quick-connect plug structure 1, the buffer member 12 will abut between the quick-connect plug structure 1 and the battery pack 3, thereby playing a buffering role, and at the same time can reduce the transmission of vibration between the battery pack 3 and the power distribution unit 2 during the driving of the vehicle.

[0041] Optionally, the buffer member 12 may be a rubber pad, a foam pad, or the like.

[0045] Another embodiment of the present invention provides a power distribution unit 2, which includes the quick-connect plug structure 1 of any of the above embodiments.

[0046] In one embodiment, a high-voltage device is disposed inside the power distribution unit 2. When the quick-connect plug structure 1 is connected to the power distribution unit 2, the high-voltage device is connected to at least part of the multiple connectors 11 of the quick-connect plug structure 1 through a copper busbar.

[0047] Optionally, the high-voltage device of the power distribution unit 2 is connected to the high-voltage terminal 110 of the quick-connect plug structure 1 through a copper busbar to ensure the flow rate through the copper busbar.

[0048] Another embodiment of the present invention provides a vehicle, which includes the power distribution unit 2 of any one of the above embodiments.

[0049] In one embodiment, if Figure 2As shown, the vehicle includes a battery pack 3. When the battery pack 3 is assembled on the vehicle, the connection terminal 30 of the battery pack 3 is docked with the quick-connect plug structure 1 of the power distribution unit 2, thereby completing the connection between the battery pack 3 and the power distribution unit 2.

[0050] The utility model provides a quick-connect plug structure so that after the vehicle's battery pack is assembled, the power distribution unit and the battery pack can be directly connected, which effectively reduces the complexity of the mechanical connection, improves the stability and mechanical reliability of the electrical connection, shortens the flow path of the DC current, increases the current output capacity of the battery pack, saves high-voltage wiring harnesses and connecting copper bars, and reduces the cost of the entire vehicle.

[0051] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
