[0036] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0037] The following is for reference. Figures 1-6 The power distribution box 100 according to an embodiment of the present utility model can be applied to a battery pack, and the power distribution box 100 or the battery pack can be applied to a vehicle.

[0038] Combination Figures 1-2 As shown, the distribution box 100 according to this utility model mainly includes: a box body 10 and an electrical connection assembly 30.

[0039] The enclosure 10 has an internal receiving space 101, and at least one side of the enclosure 10 has a window 11 connected to the receiving space 101. The receiving space 101 is suitable for housing an electrical component 20. The electrical connection component 30 includes a mounting member 31, which is detachably mounted on the window 11. The mounting member 31 is suitable for housing at least one of a first connector 32001 and a second connector 32002, which are suitable for electrical connection with external interfaces of different specifications and models.

[0040] Specifically, the electrical component 20 is housed within the accommodating space 101. The housing 10 can integrate the electrical component 20 into a single component, which not only prevents damage to the electrical component 20 from external objects and impacts, thus protecting the electrical component 20, but also enables functional integration.

[0041] Furthermore, a window 11 is provided on at least one side of the enclosure 10 in the circumferential direction. The window 11 is connected to the receiving space 101, and the electrical connection component 30 is provided in the window 11. In this way, while retaining the basic load-bearing and mounting bracket structure and ensuring the structural strength of the enclosure 10, the electrical connection component 30 can be electrically connected to the electrical component 20 in the receiving space 101, thereby forming the basic structure of the distribution box 100. As long as the electrical connection component 30 is electrically connected to the external interface, the distribution box 100 can be connected to the circuit and the distribution box 100 can function.

[0042] Considering the different specifications and models of external interfaces in different application scenarios, the electrical connection assembly 30 can include a mounting member 31, and the mounting member 31 can be detachably disposed on the opening 11. The mounting member 31 is adapted to accommodate at least one of a first connector 32001 and a second connector 32002, which are adapted to be electrically connected to external interfaces of different specifications and models.

[0043] The mounting component 31 is adapted to accommodate at least one of the first connector 32001 and the second connector 32002. Specifically, the mounting component 31 can be adapted to accommodate only the first connector 32001, only the second connector 32002, or both the first connector 32001 and the second connector 32002. Furthermore, it is understood that the mounting component 31 can have different types depending on the available configurations.

[0044] In practical applications, the mounting component 31 at the opening 11 can be replaced according to the actual application scenario and the specifications of the external interface of the distribution box 100. At least one of the corresponding first connector 32001 and second connector 32002 can be set on the mounting component 31, so that the distribution box 100 can be compatible with the specifications of the external interface according to the customer. This can improve the compatibility of the distribution box 100 and reduce development costs.

[0045] It should be noted that in the illustrations of this application, only the case where a window 11 is provided on one circumferential side of the housing 10 is used as an example. In other embodiments of this application, windows 11 are provided on multiple circumferential sides of the housing 10, which allows for the provision of a greater number of mounting components 31 or even electrical connection components 30 on the housing 10, or the provision of more types of mounting components 31 or even electrical connection components 30, which will not be elaborated here.

[0046] Therefore, by detachably mounting the mounting piece 31 to the opening 11, the mounting piece 31 at the opening 11 can be replaced according to the specifications of the external interface, and at least one of the corresponding first connector 32001 and second connector 32002 can be mounted on the mounting piece 31. This allows the distribution box 100 to adapt to external interfaces of different specifications, improves the compatibility of the distribution box 100, and reduces development costs.

[0047] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the housing 10 is provided with a plurality of first mounting holes 12 at circumferential intervals corresponding to the window 11, and the mounting component 31 is provided with a plurality of second mounting holes 311. The plurality of second mounting holes 311 and the plurality of first mounting holes 12 correspond one-to-one and are detachably connected and fixed by a first fastener.

[0048] Specifically, by providing multiple first mounting holes 12 at circumferential intervals on the housing 10 corresponding to the opening 11, and providing multiple second mounting holes 311 on the electrical connection assembly 30, and by making the multiple second mounting holes 311 correspond one-to-one with the multiple first mounting holes 12, it is only necessary to pass the first fastener through the first mounting holes 12 and the second mounting holes 311 simultaneously and perform a fastening action to achieve a detachable connection between the mounting component 31 and even the electrical connection assembly 30 and the housing 10. This not only facilitates the installation and disassembly of the electrical connection assembly 30 and the housing 10 and the replacement of the electrical connection assembly 30, but also ensures the reliability of the connection between the mounting component 31 and even the electrical connection assembly 30 and the housing 10.

[0049] It should be noted that there is only one housing 10, which can keep the setting of multiple first mounting holes 12 unchanged, and make the structure and distribution of multiple second mounting holes 311 on various mounting parts 31 consistent. That is, no matter what kind of mounting part 31, it can be connected to the housing 10 through the first fastener. The housing 10 can be adapted to different kinds of mounting parts 31, thereby simplifying the structure of the housing 10 and reducing development costs.

[0050] Combined with Figure 2, Figure 5 and Figure 6 As shown, the electrical connection assembly 30 may further include a connector 32, which includes at least one of a first connector 32001 and a second connector 32002. The connector 32 is adapted to be disposed on the mounting member 31 and adapted to be electrically connected to the electrical assembly 20 disposed within the receiving space 101. The connector 32 is also adapted to be electrically connected to external interfaces of different specifications and models.

[0051] Specifically, the connector 32 is mounted on the mounting piece 31, thus forming the basic structure of the electrical connection assembly 30. After the electrical assembly 20 is placed in the receiving space 101, it is only necessary to place the mounting piece 31 on the opening 11, so that the connector 32 is located on the side of the mounting piece 31 away from the receiving space 101, that is, to place the connector 32 on the outside of the enclosure 10, and then electrically connect the connector 32 to the electrical assembly 20 in the receiving space 101 to complete the basic structure of the distribution box 100.

[0052] At this time, when the distribution box 100 needs to work, simply connect the connector 32 to the corresponding external interface to connect the distribution box 100 to the circuit and enable the distribution box 100 to function.

[0053] Furthermore, the connector 32 may include at least one of the first connector 32001 and the second connector 32002, and the first connector 32001 and the second connector 32002 may be adapted to be electrically connected to external interfaces of different specifications and models. In this way, only by changing the mounting part 31 and the connector 32 according to the specific specifications and models of the external interface, that is, changing the type of electrical connection component 30, electrical connection with the corresponding specifications and models of the external interface can be achieved, thus realizing compatibility with external interfaces of different specifications and models.

[0054] The external interfaces include multiple interfaces, including at least a battery interface and an output load interface. Multiple connectors 32 can be configured so that multiple connectors 32 can be adapted to multiple external interfaces, thereby allowing the distribution box 100 to be located between the battery and the output load, ensuring the normal operation of the output load.

[0055] Furthermore, by setting multiple connectors 32 on the mounting piece 31, when it is necessary to change the type of connector 32 to adapt to the external interface, it is only necessary to disconnect the current type of mounting piece 31 from the housing 10 and connect the other required mounting piece 31 to the housing 10. This allows for the simultaneous replacement of multiple types of connectors 32, eliminating the need to replace multiple connectors 32 one by one. This simplifies the assembly process and improves assembly efficiency.

[0056] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the mounting component 31 is provided with a plurality of third mounting holes 312 at intervals, and the connector 32 is provided with a plurality of fourth mounting holes 321 at intervals. The plurality of fourth mounting holes 321 and the plurality of third mounting holes 312 correspond one-to-one and are connected by a second fastener.

[0057] Specifically, by providing multiple third mounting holes 312 at intervals on the mounting component 31 and multiple fourth mounting holes 321 at intervals on the connector 32, and by making the multiple fourth mounting holes 321 correspond one-to-one with the multiple third mounting holes 312, the connection between the connector 32 and the mounting component 31 can be achieved simply by having the second fastener pass through both the third mounting holes 312 and the fourth mounting holes 321 and tighten them. This achieves the overall structure of the electrical connection assembly 30, making the electrical connection assembly 30 simpler and more reliable.

[0058] Furthermore, combined Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the mounting component 31 is also provided with a mounting interface 313, and a plurality of third mounting holes 312 are arranged circumferentially at intervals on the mounting interface 313. The connector 32 passes through the mounting interface 313 at least partially and is electrically connected to the electrical component 20.

[0059] Specifically, considering that the connector 32 needs to be electrically connected to the electrical component 20 within the receiving space 101, a mounting interface 313 is provided on the mounting member 31, and multiple third mounting holes 312 are spaced circumferentially around the mounting interface 313. This allows at least a portion of the connector 32 to pass through the mounting interface 313 and extend into the receiving space 101 when the connector 32 is connected and fixed to the mounting member 31. This facilitates electrical connection between the connector 32 and the electrical component 20, ensuring the normal operation of the distribution box 100.

[0060] Combination Figure 5 and Figure 6As shown, the mounting component 31 has a protrusion 314, and both the third mounting hole 312 and the mounting interface 313 are located on the protrusion 314. This arrangement ensures the stable mounting of the connector 32 on the mounting component 31 while allowing the protrusion 314 to avoid interference with the electrical components 20 within the accommodating space 101, thus optimizing the structural design of the mounting component 31 and improving the structural reliability of the distribution box 100.

[0061] Combination Figures 3-4 As shown, the distribution box 100 may further include an electrical component 20, which may include a controller 21 and multiple functional devices. The controller 21 integrates a high-voltage sampling module and a low-voltage control module and is equipped with a circuit board 211. The multiple functional devices include a current detection device 25, a first switching device 22 and a second switching device 24. The current detection device 25, the first switching device 22 and the second switching device 24 are electrically connected to the circuit board 211 through inserts 26.

[0062] Specifically, the controller 21 integrates a high-voltage sampling module and a low-voltage control module and is equipped with a circuit board 211. To ensure the functionality of the distribution box 100, the current detection device 25, the first switching device 22, and the second switching device 24 need to be electrically connected to the circuit board 211, so that the controller 21 can perform high-voltage sampling and low-voltage control on the current detection device 25, the first switching device 22, and the second switching device 24.

[0063] Unlike existing technologies where the current sensing device, the first switching device, and the second switching device are electrically connected to the circuit board via wiring harnesses, this application removes the casing from the current sensing device 25, the first switching device 22, and the second switching device 24, allowing them to be electrically connected to the circuit board 211 via inserts 26. This creates an integrated high- and low-voltage structure that eliminates the need for wiring harnesses and allows for a miniaturized, highly integrated arrangement of the electrical components 20, improving the space utilization of the distribution box 100.

[0064] Among them, the current detection device 25 is not limited to a shunt, the first switching device 22 is not limited to a relay, and the second switching device 24 is not limited to a relay.

[0065] Furthermore, combined Figure 3 and Figure 4As shown, the insert 26 may include a first electrical connection portion 261 and a second electrical connection portion 262 that are interconnected. The first electrical connection portion 261 is sheet-shaped and has a first through hole. The current detection device 25, the first switching device 22 and the second switching device 24 are respectively provided with second through holes. The second through holes correspond to the first through holes and are connected by a third fastener 40. The second electrical connection portion 262 is strip-shaped. The circuit board 211 is provided with a plurality of insertion holes 2111. The second electrical connection portion 262 is inserted into and welded to the insertion holes 2111.

[0066] Specifically, it can be understood that one end of the insert 26 is electrically connected to the current detection device 25, the first switching device 22 or the second switching device 24, and the other end of the insert 26 is electrically connected to the circuit board 211.

[0067] By including a first electrical connection portion 261 and a second electrical connection portion 262 that are interconnected, the first electrical connection portion 261 is electrically connected to the current detection device 25, the first switching device 22 or the second switching device 24, and the second electrical connection portion 262 is electrically connected to the circuit board 211, which facilitates the setting and electrical connection of the insert 26.

[0068] Specifically, the first electrical connection part 261 is plate-shaped and has a first through hole. Correspondingly, the current detection device 25, the first switching device 22, and the second switching device 24 are respectively provided with second through holes, so that the second through holes correspond to the first through holes. In this way, the third fastener 40 only needs to pass through the first through hole and the second through hole at the same time and perform a fastening effect to realize the electrical connection between the insert 26 and the current detection device 25, the first switching device 22, or the second switching device 24. This makes the electrical connection between the insert 26 and the current detection device 25, the first switching device 22, or the second switching device 24 simpler and more reliable.

[0069] The sheet-like design facilitates at least partial contact between the second electrical connection 262 and the current detection device 25, the first switching device 22, or the second switching device 24, thereby further improving the reliability of the electrical connection.

[0070] Furthermore, the second electrical connection portion 262 is elongated and multiple insertion holes 2111 are provided on the circuit board 211. In this way, the second electrical connection portion 262 of each plug-in 26 can be inserted into the corresponding insertion hole 2111. The electrical connection between the plug-in 26 and the circuit board 211 can be achieved simply by inserting the second electrical connection portion 262 into the insertion hole 2111 and soldering the second electrical connection portion 262 to the circuit board 211, making the electrical connection between the plug-in 26 and the circuit board 211 simpler and more reliable.

[0071] The elongated design facilitates the insertion and mating of the second electrical connection part 262 and the insertion hole 2111, thereby improving assembly efficiency and reliability.

[0072] Combination Figure 3 As shown, the functional device may also include: a safety protection device 23, and the electrical connection assembly 30 may also include a connector 32. The connector 32 may be multiple and may include at least: a first connector 3201, a second connector 3202, a third connector 3203 and a fourth connector 3204. The first connector 3201, the safety protection device 23, the first switching device 22 and the second connector 3202 are electrically connected in sequence, and the third connector 3203, the current detection device 25, the second switching device 24 and the fourth connector 3204 are electrically connected in sequence.

[0073] In this way, two circuits can be formed within the distribution box 100. One of the first connector 3201 and the second connector 3202 can be electrically connected to the positive terminal of the battery, and the other of the first connector 3201 and the second connector 3202 can be electrically connected to the positive terminal of the output load. One of the third connector 3203 and the fourth connector 3204 can be electrically connected to the negative terminal of the battery, and the other of the third connector 3203 and the fourth connector 3204 can be electrically connected to the negative terminal of the output load.

[0074] The first connector 3201 and the safety protection device 23, the safety protection device 23 and the first switching device 22, the first switching device 22 and the second connector 3202, the third connector 3203 and the current detection device 25, the current detection device 25 and the second switching device 24, and the second switching device 24 and the fourth connector 3204 are all electrically connected via copper busbars 27. This fully utilizes the high conductivity, mechanical strength, corrosion resistance, and safety features of the copper busbars 27, eliminating the need for wiring harnesses and improving the performance of the distribution box 100.

[0075] Furthermore, combined Figure 3 As shown, the copper busbar 27 is at least partially elongated, and both ends of the copper busbar 27 are provided with third through holes 271. A fourth through hole 322 is provided on multiple functional devices and multiple connectors 32. The fourth through hole 322 corresponds to the third through hole 271 and is electrically connected through a fourth fastener 50.

[0076] Specifically, it is understood that the copper busbar 27 needs to be electrically connected to the connector 32 and one functional device simultaneously, or to two functional devices simultaneously. By making the copper busbar 27 at least partially elongated, the copper busbar 27 can be adapted to the distance between the connector 32 and the functional device, or to the distance between two functional devices.

[0077] Furthermore, by providing third through holes 271 at both ends of the copper busbar 27, and correspondingly providing fourth through holes 322 in multiple functional devices and multiple connectors 32, the electrical connection between the copper busbar 27 and the connectors 32 or functional devices can be made simpler and more reliable by having the fourth fastener 50 pass through both the fourth through hole 322 and the third through hole 271 simultaneously for fastening, regardless of which component the copper busbar 27 is electrically connected to.

[0078] It should be noted that, in combination Figure 4 As shown, the copper busbar 27 and the insert 26 can be electrically connected to the same functional device simultaneously. At this time, the second and fourth through holes 322 of the functional device coincide, and the third through hole 271 of the copper busbar 27 corresponds to the first through hole of the insert 26. It is only necessary to pass the insert 26, the copper busbar 27 and the functional device through the third fastener 40 or the fourth fastener 50 at the same time and perform a fastening action to achieve electrical connection, thereby further simplifying the assembly.

[0079] It should be noted that the current detection device 25, the first switching device 22, and the second switching device 24 each have a high-voltage module and a low-voltage module. Both the low-voltage and high-voltage modules are electrically connected to the circuit board 211 via a connector 26, and the high-voltage modules are also electrically connected to each other via a copper busbar 27. The safety protection device 23 does not have a low-voltage module; it is only electrically connected to other functional devices via a copper busbar 27.

[0080] Combination Figure 1 and Figure 2 As shown, the distribution box 100 may further include: a cover plate 13, the upper end of the box body 10 is open, and the cover plate 13 is detachably disposed on the upper end of the box body 10 and seals the upper end of the box body 10.

[0081] Specifically, by opening the top of the distribution box 100, it is convenient to install the electrical components 20 inside the distribution box 100 and to facilitate the electrical connection between the electrical components 20 and the connector 32. After completing the installation of the electrical components 20 in the box 10, the connection between the electrical connection components 30 and the box 10, the electrical connection inside the electrical components 20, and the connection between the electrical components 20 and the connector 32, the cover plate 13 can be installed on the top of the box 10 and sealed to prevent the intrusion of foreign objects or the impact of external forces from damaging the structure of the distribution box 100 and to ensure the normal operation of the distribution box 100.

[0082] It is understandable that when the distribution box 100 malfunctions, or when the electrical connection component 30 needs to be replaced, the cover plate 13 can be removed from the top of the box 10, which facilitates the disassembly, assembly and maintenance of the distribution box 100.

[0083] The battery pack according to this utility model mainly includes the aforementioned distribution box 100. Specifically, the distribution box 100 has high compatibility and high integration.
