[0043] Through the above structure, all positive output ports 40 are installed in the first mounting area 102, and all negative output ports 50 are installed in the second mounting area 104, so that the positive output ports 40 are separated from the negative output ports 50. Therefore, the positive output ports 40 and the negative output ports 50 do not need to be arranged crosswise in the power distribution unit 100, and the positive output ports 40 and the negative output ports 50 can be routed separately; during the assembly process of the power distribution unit 100, it is only necessary to install all positive output ports 40 in the first mounting area 102 and then install all negative output ports 50 in the second mounting area 104; the assembly process of the power distribution unit 100 in this embodiment is more convenient.

[0045] Specifically, in this embodiment, the main body 10 is made of sheet metal and has a drawer-like structure, with the first mounting area 102 and the second mounting area 104 both located within the main body 10. Each positive electrode interface 20 can correspond to multiple positive electrode output ports 40, and each negative electrode interface 30 can also correspond to multiple negative electrode output ports 50.

[0047] In some embodiments, each positive electrode interface 20 is electrically connected to at least two positive electrode output ports 40 , and each negative electrode interface 30 is electrically connected to at least two negative electrode output ports 50 .

[0048] Through the above structure, at least two positive output ports 40 electrically connected to the same positive interface 20 can independently output power to the positive interface 20, thereby increasing the adjustable range of the output power of the positive interface 20. At least two negative output ports 50 electrically connected to the same negative interface 30 can independently output power to the positive interface 20, thereby increasing the adjustable range of the output power of the negative interface 30.

[0049] Specifically, in this embodiment, part of the positive interface 20 corresponds to two positive output ports 40, and another part of the positive interface 20 corresponds to three positive output ports 40; part of the negative interface 30 corresponds to two negative output ports 50, and another part of the negative interface 30 corresponds to three negative output ports 50.

[0050] In other embodiments, the positive electrode interface 20 may also correspond to other numbers of positive electrode output ports 40 , such as four; and the negative electrode interface 30 may also correspond to other numbers of negative electrode output ports 50 .

[0051] In some embodiments, the power distribution unit 100 also includes a first electrical connector 60 and a second electrical connector 70, the first electrical connector 60 includes a first output terminal 62 and multiple first input terminals 64, the first output terminal 62 is electrically connected to the positive interface 20, and each first input terminal 64 is electrically connected to a corresponding positive output port 40.

[0052] The second electrical connector 70 includes a second output terminal 72 and a plurality of second input terminals 74 . The second output terminal 72 is electrically connected to the negative electrode interface 30 , and each second input terminal 74 is electrically connected to a corresponding negative electrode output port 50 .

[0053] Through the above structure, the same first electrical connector 60 can electrically connect a positive electrode interface 20 with all corresponding positive electrode output ports 40, and the same second electrical connector 70 can electrically connect a negative electrode interface 30 with all corresponding negative electrode output ports 50; thereby further facilitating the assembly process of the power distribution unit 100 in this embodiment.

[0054] Specifically, in this embodiment, the first electrical connector 60 and the second electrical connector 70 have the same structure. The first electrical connector 60 is a sheet-shaped copper busbar structure. One end of the first electrical connector 60 is electrically connected to a corresponding positive electrode interface 20 through a screw, and the other opposite end of the first electrical connector 60 and the side of the first electrical connector 60 can be electrically connected to the corresponding positive electrode output port 40 through a bolt; one end of the second electrical connector 70 is electrically connected to a corresponding negative electrode interface 30 through a screw, and the other opposite end of the second electrical connector 70 and the side of the second electrical connector 70 can be electrically connected to the corresponding negative electrode output port 50 through a bolt.

[0055] In other embodiments, the first electrical connector 60 and the second electrical connector 70 may also be other structures, such as electrical connection wires.

[0056] In some embodiments, the first electrical connector 60 includes a main body 66 and a side protrusion 68, the main body 66 is a strip-shaped sheet conductor, the side protrusion 68 is connected to the side of the main body 66, the first output end 62 is located at one end of the main body 66, and the first input end 64 is located at the other opposite end of the main body 66 or the side protrusion 68.

[0057] Through the above structure, the side protrusion 68 protrudes relative to the main body 66, and the first input end 64 is provided on the side protrusion 68, so that the first input end 64 located on the side protrusion 68 has a larger operating space when electrically connecting with the corresponding positive output port 40, and thus the first input end 64 located on the side protrusion 68 and the corresponding positive output port 40 are easier to electrically connect.

[0058] Specifically, in this embodiment, the side protrusion 68 is a sheet-like structure similar to a trapezoid, and through holes are opened at the first output end 62 and the first input end 64. The first output end 62 and the corresponding positive electrode interface 20 can be electrically connected by screws, and the first input end 64 and the corresponding positive electrode output port 40 can also be electrically connected by screws.

[0059] In other embodiments, the first output terminal 62 and the corresponding positive electrode interface 20 can also be electrically connected in other ways, for example, the first output terminal 62 is inserted into the corresponding positive electrode interface 20; the first input terminal 64 and the corresponding positive electrode output port 40 can also be electrically connected in other ways, for example, the first input terminal 64 is inserted into the corresponding positive electrode output port 40.

[0062] With the above structure, the positive output port 40 is disposed on the end surface of the first mounting protrusion 12 facing away from the bottom wall of the mounting cavity 106, so that the first mounting protrusion 12 can support the first output end 62 electrically connected to the positive output port 40. Simultaneously, the negative output port 50 is disposed on the end surface of the second mounting protrusion 14 facing away from the bottom wall of the mounting cavity 106, so that the second mounting protrusion 14 can support the second output end 72 electrically connected to the negative output port 50. Consequently, the first electrical connector 60 and the second electrical connector 70 can be more stably mounted within the mounting cavity 106. Furthermore, a gap can be provided between the first electrical connector 60 and the second electrical connector 70 and the bottom wall of the mounting cavity 106, preventing dust and other debris on the bottom wall of the first mounting cavity 106 from directly contacting the first electrical connector 60 and the second electrical connector 70.

[0063] Specifically, in this embodiment, the first mounting protrusion 12 and the second mounting protrusion 14 both have a structure similar to a rectangular parallelepiped, and each first mounting protrusion 12 is provided with two positive output ports 40. The two positive output ports 40 provided on the same first mounting protrusion 12 are independent of each other, and the two positive output ports 40 on the same first mounting protrusion 12 respectively correspond to the side protrusions 68 on different first electrical connectors 60.

[0064] In other embodiments, the first mounting protrusion 12 and the second mounting protrusion 14 may also be other structures, such as cylinders; and the first mounting protrusion 12 may also be provided with other numbers of positive electrode output ports 40 , such as one or three.

[0065] Please refer to Figure 3 and Figure 4 In some embodiments, one first mounting protrusion 12 is provided with at least two positive output ports 40 , and one second mounting protrusion 14 is provided with at least two negative output ports 50 .

[0066] The first mounting protrusion 12 includes a first separator 122 , and the second mounting protrusion 14 includes a second separator 142 ; the first separator 122 separates all positive output ports 40 located on the same first mounting protrusion 12 , and the second separator 142 separates all negative output ports 50 located on the same second mounting protrusion 14 .

[0067] Through the above structure, all the positive output ports 40 arranged on the same first mounting protrusion 12 are independent of each other, and the first separator 122 separates all the positive output ports 40 located on the same first mounting protrusion 12 so that all the first input terminals 64 connected to the same first mounting protrusion 12 will not contact each other and cause a short circuit.

[0068] All negative output ports 50 arranged on the same second mounting protrusion 14 are also independent of each other. The second separator 142 separates all negative output ports 50 located on the same second mounting protrusion 14 so that all second input terminals 74 connected to the same second mounting protrusion 14 will not contact each other and cause a short circuit.

[0069] Specifically, in this embodiment, one first mounting protrusion 12 is provided with one first mounting protrusion 12, and one second mounting protrusion 14 is provided with two negative electrode output ports 50.

[0070] In other embodiments, the first separator 122 may also be of other structures, such as an arc-shaped sheet structure; the structure of the second separator 142 may also be different from that of the first separator 122 .

[0071] See also Figure 5 and Figure 6In some embodiments, the power distribution unit 100 further includes a first electrical adapter 80 and a second electrical adapter 90, one end of the first electrical adapter 80 is electrically connected to the first output terminal 62, and the other end of the first electrical adapter 80 is electrically connected to the corresponding positive electrode interface 20; one end of the second electrical adapter 90 is electrically connected to the second output terminal 72, and the other end of the second electrical adapter 90 is electrically connected to the negative electrode interface 30.

[0072] Through the above structure, the first electrical adapter 80 is used to electrically connect the first output end 62 with the corresponding positive electrode interface 20, and the second electrical adapter 90 is used to electrically connect the second output end 72 with the negative electrode interface 30; so that when the distances between different positive electrode interfaces 20 and the corresponding first output ends 62 are different, the structure of each first electrical connector 60 can remain consistent; at the same time, when the distances between different negative electrode interfaces 30 and the corresponding second output ends 72 are different, the structure of each second electrical connector 70 can also remain consistent, so that the first electrical connector 60 and the second electrical connector 70 can be mass-produced.

[0073] Specifically, in this embodiment, the first electrical adapter 80 and the second electrical adapter 90 are both copper busbar structures. In other embodiments, the first electrical adapter 80 and the second electrical adapter 90 can also be other structures, such as electrical connecting wires.

[0074] In some embodiments, the first electrical adapter 80 includes a first sub-copper busbar 82, a first electrical connection end 84, and a second electrical connection end 86. The first electrical connection end 84 and the second electrical connection end 86 are respectively connected to the two sides of the first sub-copper busbar 82. The first electrical connection end 84 is located at one end of the first sub-copper busbar 82, and the second electrical connection end 86 is located at the other opposite end of the first sub-copper busbar 82. The first electrical connection end 84 is electrically connected to the first output end 62, and the second electrical connection end 86 is connected to the positive electrode interface 20.

[0075] The second electrical adapter 90 includes a second sub-copper busbar 92, a third electrical connection end 94 and a fourth electrical connection end 96.

[0077] Through the above structure, adjacent ones of all first sub-copper bars 82 and all second sub-copper bars 92 overlap with each other, so that the space occupied by all first electrical adapters 80 and all second electrical adapters 90 is smaller; and all first electrical adapters 80 and all second electrical adapters 90 are connected into a whole, and the structure is more stable.

[0078] In addition, the surfaces of the first copper sub-bars and the first copper sub-bars are both provided with an insulating layer, so that no two adjacent first copper sub-bars will be electrically connected to each other and cause a short circuit.
