[0026] This application provides a power distribution box, which will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 3 The diagram shows a structural schematic of a distribution box according to an embodiment of this application. (Refer to...) Figure 4 This diagram illustrates the mating of the first electrical connector and the second electrical connector provided in an embodiment of this application. (Refer to...) Figure 5 , showed Figure 4 A magnified view of the area at position A in the middle, refer to... Figure 6 This diagram illustrates the mating of the first electrical connector and the first adapter provided in an embodiment of this application. (Refer to...) Figures 7 to 8 The diagram shows a structural schematic of the first housing provided in an embodiment of this application.

[0028] like Figures 1 to 3As shown, this application provides a power distribution box 100 applied to a vehicle. The vehicle includes a body 200, and the power distribution box 100 includes: a first box 1 and a second box 2. The first box 1 and the second box 2 are adapted to be disposed on opposite sides of the body 200. The first box 1 is provided with a plurality of first electrical connectors 11, and the second box 2 is provided with a plurality of second electrical connectors 21. At least one of the first electrical connectors 11 and the second electrical connectors 21 is adapted to pass through the body 200. In this case, a first electrical connector 11 and a second electrical connector 21 are positioned opposite each other and plugged into each other.

[0029] In this embodiment, the first housing 1 is provided with multiple first electrical connectors 11, and the second housing 2 is provided with multiple second electrical connectors 21, with one first electrical connector 11 and one second electrical connector 21 positioned opposite each other. Thus, by plugging in one first electrical connector 11 and one second electrical connector 21, the first housing 1 and the second housing 2 can be electrically connected, thereby achieving reliable power transmission. More importantly, the plugging in of the first electrical connectors 11 and the second electrical connectors 21 can be completed simultaneously with the assembly of the first housing 1 and the second housing 2 onto the vehicle body 200, eliminating the need for additional connections. This effectively shortens the overall installation time of the distribution box 100, improving vehicle production efficiency.

[0030] In related technologies, the lower and upper housings (corresponding to the first housing 1 and the second housing 2 in this application embodiment) are respectively provided with copper busbars, and the copper busbars of the lower and upper housings are usually connected by bolts. Specifically, during the final assembly process, it is usually necessary to open the lower and upper housings, and then bolt the copper busbars of the lower and upper housings through the intermediate copper post to achieve electrical connection before closing the cover. The entire final assembly process takes about 215 seconds. However, the plug-in structure of this application embodiment does not require opening or closing the cover, and the efficiency of the plug-in method is much higher than that of the bolt connection method. According to tests, the final assembly time of the distribution box 100 in this application embodiment is about 39 seconds, which can greatly save the final assembly time and improve the production efficiency of the vehicle.

[0031] It should be noted that the "first electrical connector 11" and "second electrical connector 21" in this application embodiment refer to structural components formed by processing conductive materials, so that electrical energy can be transmitted when the first electrical connector 11 and the second electrical connector 21 are plugged in. The conductive materials include, but are not limited to, copper, aluminum, gold, silver, etc., and are not limited here; those skilled in the art can choose according to actual needs. Furthermore, this application embodiment does not limit the number of the first electrical connector 11 and the second electrical connector 21; those skilled in the art can adjust them according to actual needs. It is understood that the number of the first electrical connector 11 should be consistent with the number of the second electrical connector 21 to achieve reliable electrical energy transmission.

[0032] In some optional embodiments of this application, the first electrical connector 11 is provided with a plug-in slot 111, and the second electrical connector 21 is provided with a plug-in portion 211 at a corresponding position in the plug-in slot 111, the plug-in portion 211 being plugged into the plug-in slot 111. It is understood that the plug-in portion 211 and the plug-in slot 111 are mutually compatible structures so that they cooperate with each other to achieve plugging.

[0033] Taking a case where the first housing 1 is located on the lower side of the vehicle body 200 and the second housing 2 is located on the upper side of the vehicle body 200, in practical applications, the second housing 2 is usually installed onto the vehicle body 200 first, and then the first housing 1 is installed onto the vehicle body 200. Based on this, since the first electrical connector 11 is provided with a plug-in slot 111 and the second electrical connector 21 is provided with a plug-in part 211, when the first housing 1 is aligned and installed onto the vehicle body 200, the plug-in slot 111 can be plugged into the plug-in part 211, thereby achieving electrical connection between the first electrical connector 11 and the second electrical connector 21.

[0034] In some alternative embodiments of this application, such as Figures 4 to 5 As shown, the first electrical connector 11 includes: a conductive body 112 and two elastic conductive elements 113; the two elastic conductive elements 113 are disposed on opposite sides of the conductive body 112 and surround the conductive body 112 to form a insertion groove 111; at least a portion of the insertion part 211 is embedded in the insertion groove 111 and abuts against at least a portion of the two elastic conductive elements 113. The conductive body 112 may be a copper busbar. It should be noted that the "elastic conductive element 113" in this embodiment refers to a structural component that combines conductivity and elastic deformation capability; it can be a single component or a structural component composed of multiple components.

[0035] In this embodiment, elastic conductive elements 113 are respectively provided on opposite sides of the conductive body 112, and the two elastic conductive elements 113 and the conductive body 112 enclose a insertion groove 111. Thus, by inserting the insertion part 211 into the insertion groove 111, the insertion part 211 can contact at least one of the elastic conductive elements 113 and the conductive body 112, thereby achieving reliable power transmission. Furthermore, since the elastic conductive elements 113 have elastic deformation capability, when the insertion part 211 is inserted into the insertion groove 111, the two elastic conductive elements 113 can tightly clamp the insertion part 211 under elastic action, thereby improving the connection reliability of the first electrical connector 11 and the second electrical connector 21, which is beneficial to further improving the reliability of power transmission.

[0036] In practical applications, the elastic conductive element 113 is typically fixedly connected to the conductive body 112, thereby achieving reliable power transmission between the elastic conductive element 113 and the conductive body 112. The fixed connection methods for the elastic conductive element 113 and the conductive body 112 in this application include, but are not limited to, bolted connections, welding, riveting, or other connection methods, and are not limited herein. Those skilled in the art can adjust them according to actual needs. Further, the conductive body 112 includes a first conductive body 1121 and a second conductive body 1122 connected to each other. The first conductive body 1121 is fixedly connected to the elastic conductive element 113, and the second conductive body 1122 is fixedly connected to the first adapter 14 (described later), thereby achieving reliable power transmission. In one embodiment, the first conductive body 1121 and the second conductive body 1122 are perpendicular to each other, i.e., the conductive body 112 is L-shaped, to better adapt to other components (such as the elastic conductive element 113 and the first adapter 14), thereby improving the ease of assembly of the distribution box 100.

[0037] Generally, to facilitate the mating of the plug portion 211 and the plug slot 111, the distance between two adjacent elastic conductive elements 113 is usually greater than the thickness of the plug portion 211. Based on this, at least a portion of each elastic conductive element 113 can be recessed towards the center of the plug slot 111 to form an abutment portion 1132, so that the distance between the two abutment portions 1132 is less than or equal to the thickness of the plug portion 211. Thus, after the plug portion 211 is inserted into the plug slot 111, reliable power transmission can be achieved through the reliable contact between the abutment portion 1132 and the plug portion 211.

[0038] In some optional embodiments of this application, the elastic conductive element 113 is an elastic copper busbar 1131, which abuts against at least a portion of the insertion part 211 under its own elasticity. It should be noted that the elastic copper busbar 1131 refers to a copper busbar with good elastic deformation capability.

[0039] In this embodiment, when the plug-in portion 211 is inserted into the plug-in slot 111, the elastic copper busbars 1131 on both sides tightly clamp the plug-in portion 211 under their own elasticity, thereby enabling reliable transmission of electrical energy between the plug-in portion 211 and the elastic copper busbars 1131.

[0040] It should be noted that the material of the elastic copper busbar 1131 is not limited in the embodiments of this application, and those skilled in the art can make adjustments according to actual needs. In one embodiment, the elastic copper busbar 1131 can be made of beryllium copper. Beryllium copper is the best performing high-grade elastic material among copper alloys, possessing a series of excellent physical, chemical, and mechanical properties such as high strength, elasticity, hardness, fatigue strength, low elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetic properties, and no sparks generated upon impact. The elastic copper busbar 1131 made of beryllium copper combines good elasticity and conductivity.

[0041] In some optional embodiments of this application, the elastic conductive element 113 includes a copper busbar and a spring steel; the copper busbar and the spring steel are arranged sequentially and connected to each other, with the spring steel away from the insertion slot 111. Under the elastic action of the spring steel, the copper busbar abuts against at least a portion of the insertion part 211. It should be noted that the copper busbar refers to an ordinary copper busbar, that is, a copper busbar with poor elastic deformation capability.

[0042] In this embodiment, since copper busbars and spring steel are provided, when the plug-in part 211 is plugged into the plug-in slot 111, under the elastic action of the spring steel, the two copper busbars located on both sides of the plug-in part 211 can deform toward the plug-in part 211, thereby tightly clamping the plug-in part 211 and realizing reliable transmission of electrical energy between the plug-in part 211 and the copper busbars.

[0043] In some alternative embodiments of this application, such as Figures 3 to 4 As shown, the vehicle includes a battery module and an electronic control module. The first housing 1 is also provided with a first connection terminal 12 and a second connection terminal 13. The first connection terminal 12 is adapted to be electrically connected to the battery module, and the second connection terminal 13 is adapted to be electrically connected to the electronic control module. Three first electrical connectors 11 are provided. The three first electrical connectors 11 are two first dedicated electrical connectors 114 and one first common electrical connector 115. One of the first dedicated electrical connectors 114 and the first common electrical connector 115 is a negative electrical connector, and the other is a positive electrical connector. One of the two first dedicated electrical connectors 114 is electrically connected to the first connection terminal 12, and the other is connected to the second connection terminal 13. The first common electrical connector 115 is electrically connected to the first connection terminal 12 and the second connection terminal 13, respectively.

[0044] In this embodiment, three first electrical connectors 11 are provided, including two first dedicated electrical connectors 114 and one first shared electrical connector 115. By electrically connecting the two first dedicated electrical connectors 114 to the first connection terminal 12 and the second connection terminal 13 respectively, and simultaneously connecting the first shared electrical connector 115 to both the first connection terminal 12 and the second connection terminal 13, the two circuits of the second enclosure 2 can share a single negative or positive electrical connector. This reduces the number of first electrical connectors 11 used, thus lowering the cost of the distribution box 100.

[0045] It should be noted that, taking the example of having three first electrical connectors 11, there are correspondingly three second electrical connectors 21. The three second electrical connectors 21 include two second dedicated electrical connectors 212 and one second common electrical connector 213. One second dedicated electrical connector 212 is plugged into one first dedicated electrical connector 114, and the second common electrical connector 213 is plugged into one first common electrical connector 115. Specifically, the second dedicated electrical connectors 212 and 114 are both either negative or positive electrical connectors, and the second common electrical connector 213 and 115 are both either negative or positive electrical connectors, thereby achieving reliable power transmission between the first electrical connectors 11 and the second electrical connectors 21.

[0046] In practical applications, the vehicle also includes a charging module, and the second housing 2 includes a third connection terminal 22, which is adapted to be electrically connected to the charging module. During charging, electrical energy output from the charging module enters the second housing 2 via the third connection terminal 22, passes through the second electrical connector 21 and the first electrical connector 11 in sequence, and is then transmitted to the first housing 1, and output from the first connection terminal 12 to the battery module, thereby achieving vehicle charging. During vehicle operation, electrical energy output from the battery module enters the first housing 1 via the first connection terminal 12, passes through the first electrical connector 11 and the second electrical connector 21 in sequence, and is then transmitted to the second housing 2, then passes through the second electrical connector 21 and the first electrical connector 11 in sequence, and is output from the third connection terminal 22 to the electronic control module, thereby achieving vehicle discharging to provide power for vehicle operation. It is understood that, in order to achieve safe and reliable transmission of electrical energy, the second housing 2 also includes other electronic components, which will not be elaborated here.

[0047] In some alternative embodiments of this application, such as Figures 3 to 5 As shown, the first housing 1 also includes: a first housing 15 and a plurality of first adapters 14; the plurality of first adapters 14 are connected to the first housing 15, and one first adapter 14 is connected to a first electrical connector 11.

[0048] In this embodiment, the first adapter 14 is provided. Through the connection between the first adapter 14 and the first housing 15, and the connection between the first electrical connector 11 and the first adapter 14, power transmission can be achieved while the first electrical connector 11 is reliably fixed. The first adapter 14 can be a copper busbar.

[0049] It should be noted that the number of first adapters 14 is not limited in this application embodiment, and those skilled in the art can adjust it according to actual needs. It is understood that the number of first adapters 14 should be consistent with the number of first electrical connectors 11 to achieve reliable power transmission. In one embodiment, taking three first electrical connectors 11 as an example, correspondingly, three first adapters 14 are also provided. Specifically, as shown... Figure 6 As shown, the three first adapters 14 are two first dedicated adapters 141 and one first common adapter 142. One first dedicated electrical connector 114 is connected to one first dedicated adapter 141, and the first dedicated adapter 141 is connected to one of the positive or negative terminals of the first connection terminal 12 via copper or aluminum wire. Another first dedicated electrical connector 114 is connected to the other first dedicated adapter 141, and the first dedicated adapter 141 is connected to one of the positive or negative terminals of the second connection terminal 13 via copper or aluminum wire. A first common electrical connector 115 is connected to the first common adapter 142, and the first common adapter 142 is connected to the other of the positive or negative terminals of the first connection terminal 12 and the second connection terminal 13 via copper or aluminum wire, thereby forming two circuits.

[0050] It is understood that the first dedicated electrical connector 114 and the first dedicated adapter 141 are both either positive or negative terminals, and the first common electrical connector 115 and the first common adapter 142 are both either positive or negative terminals. When the first dedicated electrical connector 114 and the first dedicated adapter 141 are both positive terminals, the first dedicated adapter 141 is connected to the positive terminal of the first connection terminal 12 or the second connection terminal 13. When the first common electrical connector 115 and the first common adapter 142 are both negative terminals, the first common adapter 142 is connected to the negative terminals of the first connection terminal 12 and the second connection terminal 13, respectively.

[0051] In some optional embodiments of this application, the first adapter 14 and the first electrical connector 11 are integrally formed, or the first adapter 14 and the first electrical connector 11 are detachably connected. Specifically, the first adapter 14 and the first electrical connector 11 can be connected by bolts.

[0052] In this embodiment, when the first adapter 14 and the first electrical connector 11 are integrally formed, the assembly steps of the distribution box 100 can be saved, thereby improving the assembly efficiency of the distribution box 100. Furthermore, by designing the first adapter 14 and the first electrical connector 11 as a single unit, the reliability and stability of power transmission can be improved. Generally, the first electrical connector 11, which has a plug-in slot 111, is a vulnerable component. The detachable connection between the first adapter 14 and the first electrical connector 11 allows for disassembly and replacement when the first electrical connector 11 is damaged, thereby increasing the difficulty of maintaining the distribution box 100 and reducing maintenance costs.

[0053] In some alternative embodiments of this application, such as Figure 3 , Figure 7 as well as Figure 8 As shown, the first housing 15 includes a metal housing 151 and an insulating component 152. The metal housing 151 has a receiving cavity 1513 with an opening 15111 near the second housing 2. The insulating component 152 is disposed within the receiving cavity 1513 and at least partially extends through the opening 15111. The insulating component 152 has multiple independent mounting cavities 1523. A first electrical connector 11 and a corresponding first adapter 14 are at least partially disposed within a mounting cavity 1523, and the first adapter 14 is fixedly connected to the insulating component 152. Specifically, the first housing 1 is located below the vehicle body 200. The metal housing 151 includes a top wall 1511 near the second housing 2, with the opening 15111 formed in the top wall 1511. The insulating component 152 and at least partially of the first electrical connector 11 extend through the opening 15111. The insulating component 152 refers to a structural component made of insulating material.

[0054] In this embodiment, the metal casing 151 not only protects the internal components from damage by the external environment but also shields them from external electromagnetic interference, thereby improving the safety and reliability of the distribution box 100. The insulating component 152, which has multiple independent mounting cavities 1523, allows for the placement of at least a portion of a first electrical connector 11 and its corresponding first adapter 14 within a single mounting cavity 1523. This not only isolates adjacent first electrical connectors 11 and first adapters 14 but also isolates them from the metal casing 151, achieving insulation and meeting creepage distance and clearance requirements, further enhancing the safety and reliability of the distribution box 100.

[0055] In some optional embodiments of this application, the insulating component 152 includes: a first insulating member 1521 and a second insulating member 1522 connected to each other; the first insulating member 1521 and the second insulating member 1522 are respectively disposed on opposite sides of the first adapter 14 and enclose to form a plurality of mounting cavities 1523, the second insulating member 1522 is disposed near the opening 15111, and the first adapter 14 is connected to the first insulating member 1521; wherein, the end of the second insulating member 1522 facing away from the first adapter 14 is provided with a plurality of insertion interfaces 15221, one insertion interface 15221 communicates with one mounting cavity 1523, and the insertion interface 15221 is used for the second electrical connector 21 to be inserted into the mounting cavity 1523 to be connected with the first electrical connector 11.

[0056] In this embodiment, by providing a first insulating component 1521 and a second insulating component 1522, the insulating assembly 152 is disassembled. This reduces the processing difficulty of the insulating assembly 152 while adapting it to the internal space of the metal housing 151, thus reducing the processing cost of the first housing 1 and the distribution box 100. Since the second insulating component 1522 has multiple insertion interfaces 15221, and each insertion interface 15221 communicates with a mounting cavity 1523, the insertion interfaces 15221 can act as guides during the assembly of the first housing 1 to the vehicle body 200, allowing the second electrical connector 21 to be smoothly inserted from the insertion interface 15221 into the mounting cavity 1523, thereby achieving the connection between the second electrical connector 21 and the first electrical connector 11.

[0057] It should be noted that those skilled in the art can further disassemble the first insulating member 1521 and the second insulating member 1522 as needed to adapt them to the internal space of the metal housing 151. For example... Figure 8 As shown, in one embodiment, the first insulating member 1521 can be disassembled into two parts to better fit the internal space of the metal housing 151.

[0058] Furthermore, such as Figure 7 As shown, an isolation plate 15222 can also be provided at the end of the second insulating member 1522 that is away from the first adapter member 14. The isolation plate 15222 is provided between the first dedicated electrical connector 114 and the first common electrical connector 115 to achieve isolation between the positive and negative poles, avoid short circuits and other problems, and further improve the safety and reliability of the distribution box 100.

[0059] In a specific application, the first housing 1 is located below the vehicle body 200. To prevent foreign objects (such as moisture, dust, etc.) from entering the second housing 2 above from the first housing 1 below, the first housing 1 also includes a sealing element 17. The sealing element 17 is located on the side of the top wall 1511 near the vehicle body 200 and surrounds the opening. The sealing element 17 is used to abut against the vehicle body 200, thereby achieving a reliable seal between the first housing 1 and the vehicle body 200.

[0060] In practical applications, the metal housing 151 is also provided with multiple mounting points 1512, and each mounting point 1512 is bolted to the vehicle body 200, thereby achieving reliable fixation of the first housing 1 and reliable insertion of the first electrical connector 11 and the second electrical connector 21. Generally, during final assembly, the first housing 1 needs to be pre-hung under the vehicle body 200, and then at the next installation station, the installer fixes the first housing 1 on top of the vehicle body 200 by bolting. Based on this, the metal housing 151 is also provided with a pre-hanging slot 16, and a pre-hanging block is provided at the corresponding position on the vehicle body 200. By engaging the pre-hanging slot 16 with the pre-hanging block, the first housing 1 can be pre-hung for subsequent fixation.

[0061] In some alternative embodiments of this application, such as Figure 3 As shown, the second housing 2 also includes: a second shell 24 and a plurality of second adapters 23; the plurality of second adapters 23 are connected to the second shell 24, and one second adapter 23 is connected to a second electrical connector 21. The second adapter 23 can be a copper busbar.

[0062] In this embodiment, due to the provision of the second adapter 23, the connection between the second adapter 23 and the second housing 24, and the connection between the second electrical connector 21 and the second adapter 23, can achieve reliable fixation of the second electrical connector 21 while realizing power transmission.

[0063] It should be noted that the number of second adapters 23 is not limited in the embodiments of this application, and those skilled in the art can adjust it according to actual needs. It is understood that the number of second adapters 23 should be consistent with the number of second electrical connectors 21 to achieve reliable power transmission. In one embodiment, taking three second electrical connectors 21 as an example, correspondingly, three second adapters 23 are also provided, and one second adapter 23 is connected to one second electrical connector 21, thereby achieving reliable power transmission.

[0064] In some optional embodiments of this application, the second adapter 23 and the second electrical connector 21 are integrally formed. This saves assembly steps in the distribution box 100, thereby improving assembly efficiency. Furthermore, by designing the second adapter 23 and the second electrical connector 21 as a single unit, the reliability and stability of power transmission can be improved.

[0065] In summary, the distribution box provided in this application embodiment has at least the following advantages: In this embodiment, the first housing is provided with multiple first electrical connectors, and the second housing is provided with multiple second electrical connectors, with one first electrical connector and one second electrical connector positioned opposite each other. Thus, by plugging in one first electrical connector and one second electrical connector, an electrical connection between the first and second housings can be achieved, thereby ensuring reliable power transmission. More importantly, the plugging in of the first and second electrical connectors can be completed simultaneously with the assembly of the first and second housings onto the vehicle body, eliminating the need for additional connections. This effectively shortens the overall installation time of the distribution box and improves vehicle production efficiency.

[0066] This application also provides a vehicle including the aforementioned electrical distribution box 100.

[0067] In this embodiment, the first housing 1 is provided with a first electrical connector 11, and the second housing 2 is provided with a second electrical connector 21, and the first electrical connector 11 and the second electrical connector 21 are plugged into each other. Thus, the plugging of the first electrical connector 11 and the second electrical connector 21 can be completed simultaneously with the assembly of the first housing 1 and the second housing 2 onto the vehicle body 200, eliminating the need for additional connections. This effectively shortens the overall installation time of the electrical distribution box 100 and improves vehicle production efficiency.

[0068] It should be noted that in this embodiment, the structure of the distribution box 100 is the same as that of the distribution box 100 in any of the above embodiments, and its beneficial effects are also similar, so it will not be described in detail here.
