[0086] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0087] Firstly, see... Figure 2 , Figure 3 and Figure 4 This application provides a power distribution module 100, which includes a first battery pack 120 and electrical components (not shown). The first battery pack 120 and the electrical components are electrically connected to supply power to the electrical components and ensure their stable operation. However, during use, the first battery pack 120 may experience deformation or other unexpected events due to external forces, leading to thermal runaway. Thermal runaway of the first battery pack 120 can easily spread to the electrical components, causing damage to the power distribution module 100. Those skilled in the art will readily understand that such a power distribution module 100 has relatively poor safety. When the power distribution module 100 is applied to a battery device 200 and / or electrical equipment, the safety of the battery device 200 and the electrical equipment also deteriorates.

[0088] To address this issue, the power distribution module 100 in this embodiment further includes a first mounting beam 110. The first mounting beam 110 has a mounting cavity 111, in which the first battery pack 120 is disposed, and electrical components are disposed on the outside of the first mounting beam 110. By placing the first battery pack 120 within the mounting cavity 111 of the first mounting beam 110, the first mounting beam 110 provides protection for the first battery pack 120, reducing the probability of thermal runaway caused by deformation of the first battery pack 120 due to external forces, thereby improving the safety of the power distribution module 100. Furthermore, when the power distribution module 100 is applied to the battery device 200 and / or electrical equipment, it enhances the safety of both the corresponding battery device 200 and electrical equipment.

[0089] See Figure 4 As an optional implementation, a bracket 130 is provided in the mounting cavity 111, and the first battery pack 120 is mounted in the mounting cavity 111 through the bracket 130. During the assembly of the power distribution module 100, the first battery pack 120 and the bracket 130 are first connected to form a modular structure, which facilitates the overall assembly of the first battery pack 120 and improves the assembly efficiency of the power distribution module 100.

[0090] In some embodiments, the bracket 130 can be connected to the first battery pack 120 via a snap-fit, or the bracket 130 can be provided with a slot in which the first battery pack 120 can be disposed and connected to the bracket 130. It should be noted that the connection method between the first battery pack 120 and the bracket 130 is not limited to the above example, and other connection methods known to those skilled in the art are also possible.

[0091] As an optional implementation, the bracket 130 has a receiving cavity 131, in which the first battery pack 120 is disposed. Thus, the receiving cavity 131 forms an installation space for the first battery pack 120. The cavity wall of the receiving cavity limits the position of the first battery pack 120, preventing displacement, loosening, and internal short circuits. This also prevents the first battery pack 120 from generating excessive heat due to increased internal resistance, further improving the safety of the power distribution module 100.

[0092] In this embodiment, the contour of the cavity wall of the receiving cavity 131 is adapted to the shape of the contour of the first battery pack 120; and / or, the cavity wall of the receiving cavity 131 is interference-fitted with the first battery pack 120.

[0093] like Figure 4 As shown, the outline of the first battery pack 120 can be circular, and the outline of the cavity wall of the receiving cavity 131 can also be circular. This facilitates the entry of the first battery pack 120 into the receiving cavity 131, improving the assembly efficiency of the first battery pack 120 and the support 130. It is understood that the first battery pack 120 in this embodiment includes cylindrical batteries, and the outline of the cavity wall of the receiving cavity 131 is also circular. The number of cylindrical batteries can be one, two, or more; the specific number of cylindrical batteries is not required.

[0094] For example, the shape of the outline of the first battery pack 120 can also be square, and correspondingly, the shape of the outline of the cavity wall of the receiving cavity 131 is also square. In the embodiments of this application, the shape of the outline of the first battery pack 120 and the shape of the outline of the mounting cavity 111 are not limited to the above examples.

[0095] In some embodiments, the first battery pack 120 may be fixed in the receiving cavity 131 by means of clips, bosses, etc.

[0096] As is easily understood, in this embodiment, the cavity wall of the receiving cavity 131 is interference-fitted with the first battery pack 120. In this way, the cavity wall of the receiving cavity 131 of the bracket 130 provides support and connection for the first battery pack 120, reducing the need for connection structures in the receiving cavity 131 to fix the first battery pack 120 and reducing the cost of the power distribution module 100.

[0097] As will be understood by those skilled in the art, the first battery pack 120 is disposed in the receiving cavity 131, and the bracket 130 and the first battery pack 120 together enter the mounting cavity 111 of the first mounting beam 110. The bracket 130 has an elastic deformation portion 132; the elastic deformation portion 132 is configured to deform so that the first battery pack 120 and the cavity wall of the receiving cavity 131 are in an interference fit. When the bracket 130 enters the mounting cavity 111, the cavity wall of the mounting cavity 111 generates pressure on the bracket 130. The pressure acts on the elastic deformation portion 132, causing the elastic deformation portion 132 to deform, thereby reducing the space of the receiving cavity 131, thus achieving the interference fit between the first battery pack 120 and the cavity wall of the receiving cavity 131.

[0098] See also, if possible. Figure 4 The elastic deformation portion 132 can be disposed on the top or other side of the bracket 130. Those skilled in the art will understand that the elastic deformation portion 132, disposed at any position on the bracket 130, can exert pressure on the bracket 130 through the cavity wall of the mounting cavity 111, causing the elastic deformation portion 132 to deform, further achieving an interference fit between the first battery pack 120 and the bracket 130. The elastic deformation portion 132 can be a groove-shaped structure disposed on the bracket 130. The groove-shaped structure can be a through groove or a blind groove along the thickness direction of the cavity wall of the mounting cavity 111, and there is no limitation thereto. Thus, in this embodiment, the interference fit formed between the mounting cavity 111 of the bracket 130 and the first battery pack 120 reduces the need for separate connection structures on the bracket 130 to fix the first battery pack 120, and reduces the number of connectors connecting the bracket 130 and the first battery pack 120, further reducing the cost of the power distribution module 100. It is easy to understand that when the power distribution module 100 is applied to the battery device 200 and the electrical equipment, the battery device 200 and the electrical equipment have the same beneficial effects, which will not be elaborated further.

[0099] See Figure 4 Optionally, the outer contour of the bracket 130 is adapted to the shape of the inner contour of the cavity wall of the mounting cavity 111; and / or, the bracket 130 is interference-fitted with the cavity wall of the mounting cavity 111. Thus, the interference fit between the bracket 130 and the mounting cavity 111 ensures a secure connection between the bracket 130 and the first mounting beam 110. Simultaneously, it provides a connection structure for fixing the bracket 130 and the first mounting beam 110, thereby reducing the number of connectors and further lowering the cost of the power distribution module 100.

[0100] See Figure 4In this embodiment, a first guide portion 112 is provided inside the mounting cavity 111, and a second guide portion 133 is provided inside the bracket 130. The bracket 130 and the first mounting beam 110 are slidably connected through the first guide portion 112 and the second guide portion 133. Those skilled in the art will understand that during the assembly of the power distribution module 100, the bracket 130 and the first mounting beam 110 slide into the mounting cavity 111 of the first mounting beam 110 through the cooperation of the first guide portion 112 and the second guide portion 133, until the bracket 130 is fully installed in the mounting cavity 111 and stops sliding. Conversely, during the disassembly of the power distribution module 100, the bracket 130 and the first mounting beam 110 slide out of the mounting cavity 111 of the first mounting beam 110 through the cooperation of the first guide portion 112 and the second guide portion 133, until the bracket 130 is completely removed from the mounting cavity 111 and stops sliding. Thus, the cooperation of the first guide part 112 and the second guide part 133 facilitates the installation and disassembly of the bracket 130 and the first mounting beam 110, which helps to improve the assembly efficiency of the power distribution module 100 and reduce the disassembly difficulty of the power distribution module 100.

[0101] There are many structures in which the first guide portion 112 and the second guide portion 133 cooperate to achieve a sliding connection. As an optional implementation, one of the first guide portion 112 and the second guide portion 133 is a guide rib and the other is a guide groove.

[0102] For example, the bottom of the cavity wall of the mounting cavity 111 is provided with guide ribs, which extend along the length direction (P) of the first mounting beam 110. The bottom outer side of the bracket 130 is provided with guide grooves, which extend along the length direction (P) of the bracket 130. The guide ribs and guide grooves are positioned correspondingly, and their outlines are mutually compatible. During the assembly and disassembly of the power distribution module 100, the bracket 130 slides into and out of the mounting cavity 111 through the cooperation of the guide ribs and guide grooves.

[0103] In some embodiments, guide ribs can be provided on the bracket 130 and guide grooves can be provided on the cavity wall of the mounting cavity 111. In this way, the bracket 130 and the first mounting beam 110 can still be slidably set by the guide ribs and guide grooves.

[0104] In some embodiments, the first guide portion 112 in the mounting cavity 111 may be a shaft-shaped structure, and the second guide portion 133 on the bracket 130 may be a hole-shaped structure. The shaft-shaped structure may extend along the length direction (P) of the first mounting beam 110, and the hole-shaped structure may extend along the length direction (P) of the bracket 130. The shaft-shaped structure passes through the hole-shaped structure, and the bracket 130 and the first mounting beam 110 can still be slidably connected through the first guide portion 112 and the second guide portion 133.

[0105] It should be noted that the specific implementation structure of the first guide portion 112 and the second guide portion 133 in the embodiments of this application is not limited to the above example, and the embodiments of this application do not require specific implementation structures of the first guide portion 112 and the second guide portion 133.

[0106] For example, see Figure 2 , Figure 3 and Figure 4 The mounting cavity 111 has a first mounting opening 113; the power distribution module 100 also includes a mounting component 140, which is connected to the first mounting beam 110 and seals the first mounting opening 113.

[0107] In some embodiments, the power distribution module 100 further includes a second mounting beam 150; the second mounting beam 150 is connected to the mounting member 140, and the second mounting beam 150, the mounting member 140 and the first mounting beam 110 form a first mounting area 160; electrical components are disposed in the first mounting area 160.

[0108] The first mounting opening 113 allows the bracket 130 to enter and exit the mounting cavity 111, facilitating the mounting of the first battery pack 120 to the first mounting beam 110 via the bracket 130, and the detachment of the first battery pack 120 from the first mounting beam 110 via the bracket 130. The mounting member 140 is connected to the first mounting beam 110 and to the side of the first mounting beam 110 where the first mounting opening 113 is located, thus sealing the first mounting opening 113. The mounting member 140 extends along the width direction (Q) of the first mounting beam 110. Along the width direction (Q) of the first mounting beam 110, a second mounting beam 150 is connected to the end of the mounting member 140 opposite to the first mounting beam 110, achieving a spaced arrangement between the second mounting beam 150 and the first mounting beam 110. The second mounting beam 150 extends along the length direction (P) of the mounting member 140 and is opposite to the first mounting beam 110. Thus, the inner sides of the first mounting beam 110, the mounting member 140, and the second mounting beam 150 together form a first mounting area 160. Electrical components are housed within the first mounting area 160. This provides isolation between the first battery pack 120 and the electrical components via the first mounting beam 110, as well as isolation between the first battery pack 120 and external structural components. Simultaneously, the first mounting beam 110, mounting member 140, and second mounting beam 150 isolate the electrical components from other structural components outside the safety zone. This ensures that the power distribution module 100 meets electrical isolation requirements, guaranteeing its safety and reliability.

[0109] See Figure 2 and Figure 3In some embodiments, the mounting member 140 has a connecting cavity 144 that is opposite to and communicates with a first mounting opening 113. The connecting cavity 144 has a second mounting opening 142. The mounting member 140 also includes a cover plate 143 that blocks the second mounting opening 142. Thus,

[0110] Optionally, the mounting member 140 can be a plate-shaped structural member. Along the length direction (P) of the first mounting beam 110, the mounting member 140 partially covers the side of the first mounting opening 113 of the first mounting beam 110. The mounting member 140 has a connecting cavity 144, and the second mounting opening 142 of the connecting cavity 144 is opposite to and communicates with the first mounting opening 113. In this way, along the length direction (P) of the first mounting beam 110, the bracket 130 carrying the first battery pack 120 passes through the second mounting opening 142 and the first mounting opening 113 in sequence into the mounting cavity 111 to complete the assembly with the first mounting beam 110. The bracket 130 carrying the first battery pack 120 passes through the first mounting opening 113 and the second mounting opening 142 in sequence to disengage from the mounting cavity 111, realizing the disassembly from the first mounting beam 110.

[0111] Mounting component 140 also includes a cover plate 143, which blocks the second mounting opening 142. In this way, by blocking the second mounting opening 142 with the cover plate 143, external substances (water, dust, etc.) are prevented from entering the mounting cavity 111 through the second mounting opening 142, reducing the impact of external substances on the operation of the first battery pack 120 and improving the safety of the power distribution module 100.

[0112] See Figure 2 In some embodiments, a pressure relief device 170 is provided on the cover plate 143, which is opened under preset conditions.

[0113] It should be noted that the pressure relief device 170 in this embodiment can be an explosion-proof valve or an openable connecting hole structure. The preset conditions can be the preset opening pressure conditions or temperature conditions of the pressure relief device 170. The opening of the pressure relief device 170 can be achieved by electronic control logic or by the mechanical structure of the pressure relief device 170 itself. There are no restrictions on this. The explosion-proof valve in this embodiment is a common explosion-proof valve for those skilled in the art, and will not be described in detail here.

[0114] In some embodiments, the mounting cavity 111 also has a third mounting opening opposite the first mounting opening 113 along the length direction (P) of the first mounting beam 110. This facilitates the bracket 130 entering the mounting cavity 111 from both ends of the first mounting opening 113 and the third mounting opening along the length direction (P) of the first mounting beam 110, and facilitates the assembly of the bracket 130 and the first mounting beam 110. The power distribution module 100 also includes a sealing member 180, which is connected to the first mounting beam 110 to seal the third mounting opening.

[0115] To facilitate understanding of the embodiments of this application by those skilled in the art, the mounting cavity 111 extends through both ends of the first mounting beam 110 along the length direction (P) of the first mounting beam 110, and forms openings at both ends of the first mounting beam 110 as the first mounting opening 113 and the third mounting opening, respectively. In the embodiments of this application, the sealing member 180 is disposed on the first mounting beam 110 and located on the side where the third mounting opening is located, and seals the third mounting opening.

[0116] In conjunction with the aforementioned embodiments, the second mounting opening 142 is connected to the first mounting opening 113, and the second mounting opening 142 is blocked by the cover plate 143. This provides electrical isolation for the first battery pack 120, reducing electrical conduction between the first battery pack 120 and external structural components. In other words, it reduces the probability of short circuits within the power distribution module 100 and between the power distribution module 100 and external structural components, further ensuring the safety of the power distribution module 100.

[0117] See Figure 1 , Figure 2 and Figure 4 In some embodiments, a reinforcing structure 114 is provided on the top of the first mounting beam 110. The reinforcing structure 114 is used to connect with the upper cover 211 of the battery device 200 using the power distribution module 100. It is easy to understand that by providing the reinforcing structure 114, a height compensation effect is achieved for the first mounting beam 110. While enabling the first mounting beam 110 to connect with the upper cover 211 through the reinforcing structure 114, the structural dimensions of the first mounting beam 110 can be reduced, and the material usage of the first mounting beam 110 can be decreased, thereby reducing the weight and cost of the power distribution module 100. Furthermore, those skilled in the art will understand that by providing the reinforcing structure 114, the structural strength of the first mounting beam 110 is improved, reducing the probability of thermal runaway of the first battery pack 120 caused by deformation of the first mounting beam 110, thereby improving the safety of the power distribution module 100.

[0118] For example, the reinforcing structure 114 in the embodiments of this application can be a solid protrusion, a frame with a hollow structure, etc., and the embodiments of this application do not have specific requirements for it.

[0119] Optionally, the reinforcing structure 114 includes a first reinforcing rib 1141, which is located at the top of the first mounting beam 110 and extends along the height direction (M) of the first mounting beam 110. Thus, the first reinforcing rib 1141 extends along the height direction (M) of the first mounting beam 110 to provide height compensation for the connection between the first mounting beam 110 and the upper cover 211 of the battery device 200. Simultaneously, the first reinforcing rib 1141 disperses pressure on the upper cover 211, thereby improving the structural stability and safety of the battery device 200.

[0120] It should be noted that the first reinforcing rib 1141 in the embodiments of this application can be a plate-like structure or a column-like structure, etc., and there are no requirements in this regard.

[0121] See Figure 4 Optionally, the reinforcing structure 114 further includes a second reinforcing rib 1142, which is disposed on one side of the first reinforcing rib 1141 along the width direction (Q) of the first mounting beam 110. Thus, the second reinforcing rib 1142 has an extending tendency along the height direction (M) of the first mounting beam 110, providing height compensation for the connection between the first mounting beam 110 and the upper cover 211 of the battery device 200. Simultaneously, the first reinforcing rib 1141 and the second reinforcing rib 1142 jointly disperse the pressure on the upper cover 211, improving the structural stability and safety of the battery device 200.

[0122] It should be noted that the second reinforcing rib 1142 in this embodiment can be a plate-like structure or a column-like structure, etc., and there are no requirements in this regard.

[0123] In some embodiments, the reinforcing structure 114 further includes a third reinforcing rib 1143, which is positioned on either side of the first reinforcing rib 1141 along the width direction (Q) of the first mounting beam 110. Thus, the third reinforcing rib 1143 extends along the height direction (M) of the first mounting beam 110 to provide height compensation for the connection between the first mounting beam 110 and the upper cover 211 of the battery device 200. Simultaneously, the first reinforcing rib 1141, the second reinforcing rib 1142, and the third reinforcing rib 1143 collectively distribute pressure on the upper cover 211, thereby improving the structural stability and safety of the battery device 200.

[0124] It should be noted that the third reinforcing rib 1143 in the embodiments of this application can be a plate-like structure or a column-like structure, etc., and there are no requirements in this regard.

[0125] See Figure 4In some embodiments, the second reinforcing rib 1142 includes a first extension 1144 and a second extension 1145. The two ends of the first extension 1144, extending along the height direction (M) of the first mounting beam 110, are respectively connected to the first ends of the first mounting beam 110 and the second extension 1145. The second end of the second extension 1145 extends along the width direction (Q) of the first mounting beam 110 toward the first reinforcing rib 1141 and is connected to the first reinforcing rib 1141. And / or, the third reinforcing rib 1143 includes a third extension 1146 and a fourth extension 1147. The two ends of the third extension 1146, extending along the height direction (M) of the first mounting beam 110, are respectively connected to the first ends of the first mounting beam 110 and the fourth extension 1147. The second end of the fourth extension 1147 extends along the width direction (Q) of the first mounting beam 110 toward the first reinforcing rib 1141 and is connected to the first reinforcing rib 1141.

[0126] In some embodiments, when the second reinforcing rib 1142 includes a first extension 1144 and a second extension 1145, and the third reinforcing rib 1143 includes a third extension 1146 and a fourth extension 1147, the extension lengths of the first extension 1144 and the third extension 1146 along the height direction (M) of the first mounting beam 110 may be the same or different, and the extension lengths of the second extension 1145 and the fourth extension 1147 along the width direction (Q) of the first mounting beam 110 may be the same or different. This application embodiment does not limit this.

[0127] See Figure 4 In this embodiment, the first reinforcing rib 1141 includes a reinforcing rib body 1148 and a connecting portion 1149. Along the height direction (M) of the first mounting beam 110, the connecting portion 1149 is connected to the end of the reinforcing rib body 1148 facing away from the first mounting beam 110, and is connected to the second reinforcing rib 1142 and the third reinforcing rib 1143. In this way, the second reinforcing rib 1142 and the third reinforcing rib 1143 both provide support for the first reinforcing rib 1141 and can disperse the pressure of the upper cover 211 borne by the connecting portion 1149.

[0128] It should be noted that in this embodiment, the top surfaces of the second reinforcing rib 1142, the third reinforcing rib 1143, and the connecting portion 1149 are flush, forming a connecting plane and connecting to the upper cover 211. In some embodiments, along the height direction (M) of the first mounting beam 110, the orthographic projection of the reinforcing rib body 1148 onto the plane where the connecting portion 1149 is located is within the connecting portion 1149.

[0129] See Figure 4For example, the connecting portion 1149 may have a square cross-section to increase the top surface area of ​​the connecting portion 1149 and form a larger connecting surface for connection with the upper cover 211 of the battery device 200. In the embodiments of this application, the connecting portion 1149 and the upper cover 211 may be connected by threaded connectors, and / or the connection may be achieved by filling the space between them with curing adhesive, which is not required.

[0130] As an optional implementation, the connecting portion 1149 is provided with a connecting hole 1150 for connecting to the upper cover 211 of the battery device 200. Thus, the structure of the connecting portion 1149 facilitates the machining of the connecting hole 1150 while ensuring the structural reinforcement effect of the first reinforcing rib 1141, further enhancing the safety and connection stability between the upper cover 211 and the first mounting beam 110.

[0131] In conjunction with the foregoing embodiments, the electrical connection between the electrical components and the first battery pack 120 can be implemented in various ways. In one optional embodiment, the mounting component 140 has a connecting structure 141 that connects the first mounting area 160 and the connecting cavity 144. The power distribution module 100 also includes an electrical connector (not shown in the figure) that passes through the connecting structure 141 and connects the first battery pack 120 and the electrical components respectively, so that the first battery pack 120 and the electrical components are electrically connected.

[0132] For example, in the embodiments of this application, the communication structure 141 may be a first communication hole 1411 and a second communication hole 1421. The first communication hole 1411 is connected to the connecting cavity 144 and the second communication hole 1421 respectively, and the second communication hole 1421 is connected to the first mounting area 160. In this way, the electrical connector passes through the first communication hole 1411 and the second communication hole 1421, and the two ends of the electrical connector are connected to the first battery pack 120 and the electrical component respectively, so as to realize the electrical conduction between the first battery pack 120 and the electrical component.

[0133] It should be noted that, in this embodiment, the connecting structure 141 can also be a tubular structure, with the first mounting area 160 and the mounting cavity 111 connected through the tubular structure. An electrical connector is inserted through the tubular structure, and both ends of the electrical connector are connected to the first battery pack 120 and the electrical component, respectively, to achieve electrical conduction between the first battery pack 120 and the electrical component. The connecting structure 141 in this application is not limited to the above example.

[0134] In addition, electrical connectors can be copper busbars, aluminum busbars, wires, flexible circuit boards, etc., and there are no requirements for them. Any structural component that can enable electrical conduction between the electrical components and the first battery pack 120 is acceptable.

[0135] The electrical components in this embodiment include an electrical control unit, a first power distribution unit, and a protective component. The electrical control unit is electrically connected to the first power distribution unit and the first battery pack 120; the protective component is electrically connected to the electrical control unit and the first power distribution unit. The protective component includes circuit protection structural components such as fuses and circuit breakers.

[0136] It should be noted that the electrical control unit can be a circuit board, with integrated circuitry and control modules performing corresponding signal conversion, signal input, and output functions. Therefore, the electrical control unit is a low-voltage component. Thus, the first battery pack 120 is a low-voltage battery pack used to power the electrical control unit. For example, the voltage of the first battery pack 120 can be 12V.

[0137] See Figure 1 and Figure 2 Secondly, embodiments of this application provide a battery device 200, including: a housing 210 and a power distribution module 100 provided in the first aspect, wherein the power distribution module 100 is connected to the housing 210. This power distribution module 100 isolates itself from other structural components within the housing 210, preventing the thermal runaway of the first battery pack 120 from adversely affecting other structural components within the housing 210, and improving the safety of the battery device 200.

[0138] In some embodiments, the battery device 200 further includes a second battery pack (not shown), which is disposed within the housing 210, and the first battery pack 120, electrical components and the second battery pack are disposed separately from each other.

[0139] For example, the second battery pack may be disposed on the side of the first mounting beam 110, the side of the mounting member 140 and the side of the second mounting beam 150, and all are located outside the first mounting area 160, thereby achieving electrical separation.

[0140] It should be noted that, in this embodiment, the second battery pack is a high-voltage battery pack.

[0141] In some embodiments, a beam 220 is provided inside the housing 210, and the beam 220 is disposed between the electrical components and the second battery pack.

[0142] See Figure 2The beam 220 includes at least one crossbeam 221 along the length direction (P) of the first mounting beam 110. The crossbeam 221 is opposite to the mounting member 140 and connects the ends of the first mounting beam 110 and the second mounting beam 150 away from the mounting member 140. Thus, the crossbeam 221 completely isolates the electrical components within the first mounting area 160. The first battery pack 120 and the second battery pack are electrically isolated through the first mounting beam 110, the mounting member 140, the crossbeam 221, and the second mounting beam 150. Similarly, the electrical components in the power distribution module 100 and the second battery pack are electrically isolated through the first mounting beam 110, the mounting member 140, the crossbeam 221, and the second mounting beam 150, thereby improving the safety of the battery device 200.

[0143] See Figure 1 In this embodiment of the application, the housing 210 includes a top cover 211 and a tray 212. The tray 212 and the top cover 211 enclose a cavity 213 for accommodating the second battery pack. The mounting member 140 passes through the tray 212.

[0144] Optionally, the top cover 211 has a first opening corresponding to the position of the first mounting area 160, and the battery device 200 also includes a first sealing cover 250, which closes the first opening. Thus, the first opening facilitates the installation and maintenance of electrical components within the first mounting area 160, while the first sealing cover 250 closes the first opening, ensuring that the first mounting area 160 is not connected to the outside, thereby improving the operational safety of the electrical components.

[0145] In some embodiments, the accommodating cavity 213 is further provided with a third mounting beam 230 and a fourth mounting beam 240, which are connected to the tray 212 to enclose a second mounting area 2131. The battery device 200 also includes a second power distribution component, which is located in the second mounting area 2131. In this way, the first and second power distribution components form a redundant design, improving the operational stability of the battery device 200. Furthermore, the tray 212, the third mounting beam 230, and the fourth mounting beam 240 isolate the second power distribution component and the second battery pack, thereby improving the safety of the battery device 200.

[0146] Optionally, the top cover 211 has a second opening corresponding to the position of the second mounting area 2131, and the battery device 200 also includes a second sealing cover 260, which closes the second opening. Thus, the second opening facilitates the installation and maintenance of the second power distribution component within the second mounting area 2131, while the second sealing cover 260 closes the second opening, ensuring that the second mounting area 2131 is not connected to the outside, improving the operational safety of the second power distribution component, and thereby ensuring the safety of the battery device 200.

[0147] It should be noted that the battery device 200 in the embodiments of this application can be a battery pack, or an integrated battery chassis (CTC), etc.

[0148] Thirdly, embodiments of this application provide an electrical device, including: the power distribution module 100 in the first aspect or the battery device 200 in the second aspect.
