At the same time, the integration of the power distribution box module can simplify the internal space occupied by the battery pack.

[0005] The embodiments of this application provide the following technical solutions:

[0006] A first aspect of this application provides a distribution box integrated module, including:

[0007] The device includes a housing and at least one safety device. The housing has a connecting bar with at least three notches. The safety device includes a safety body and at least two lead-out bars. The connecting bar is electrically connected to the lead-out bars, and one end of the lead-out bars is inserted into the notches to secure the safety device.

[0008] In one feasible implementation, the safety device includes at least one of a first type of safety device and a second type of safety device, wherein the lead-out row of the first type of safety device is correspondingly connected to two adjacent recesses, and the connecting row of the second type of safety device is correspondingly connected to two spaced-apart recesses.

[0009] In one feasible implementation, at least three of the notches include a first notch, a second notch, and a third notch, which are arranged sequentially along the length of the distribution box integrated module.

[0011] In one feasible implementation, the lead-out bar includes a lead-out portion and a connecting portion, the lead-out portion being connected to the safety body, and the connecting portion extending away from the lead-out portion to form a protrusion, the protrusion being connected to the recess of the connecting bar.

[0012] In one possible implementation, at least a portion of the lead-out portion of the lead-out outlet abuts against the safety body.

[0013] In one feasible implementation, the insurance body is formed with at least two outlets, which are correspondingly provided with the outlet portions of the outlet row.

[0023] A fourth aspect of this application provides an electrical device, including a power distribution box integrated module, a power distribution box, or a battery pack.

[0024] The integrated distribution box module provided in the embodiments of this application has a connecting strip inside its housing, on which at least three notches are formed. Two notches in different relative positions can be electrically connected to fuse devices of different sizes and specifications. When using fuse devices of different sizes and specifications, the combination of notches for electrical connection can be selected according to the size characteristics of the fuse device itself, improving the adaptability of the integrated distribution box module to the size and specifications of the fuse devices, reducing mold opening costs, and optimizing internal space occupancy.

[0025] In this integrated distribution box module, the lead-out pins of the fuse device are used to connect to the connecting pins.

[0050] Distribution boxes are crucial in fields such as power batteries, serving as a core component of new energy vehicle power battery systems. They act as a bridge for power transmission, directly connecting the power battery to other high-voltage equipment, and provide technical support for system stability. To ensure the safe and efficient operation of the system under high-voltage conditions, they can transform discrete sensor data into precise system control commands, thereby achieving accurate monitoring and protection of electrical parameters, environmental conditions, and equipment operating status.

[0051] Different application scenarios require different design requirements for distribution boxes. As a key component of the distribution box, the selection of fuses requires a comprehensive evaluation of factors such as load characteristics, environmental adaptability, and material standards. The final result will inevitably affect the size of the fuses, which in turn affects the internal space distribution of the distribution box.

[0052] In related technologies, integrated modules only design the spatial layout of fuse devices of a specific size in combination with other components, and cannot be compatible with fuse devices of different sizes and specifications. This results in poor adaptability of the distribution box. When it is necessary to replace fuse devices of different sizes, it is necessary to readjust the connection method and other related designs and develop new molds according to the actual size of the components. This leads to increased mold opening costs and extended sample cycles, resulting in low production efficiency of distribution boxes, battery packs and even electrical equipment.

[0053] The integrated distribution box module provided in this application has a connecting strip inside the housing for electrically connecting a fuse device. At least three notches formed on the connecting strip are used to accommodate fuse devices of different sizes and specifications, improving the adaptability of the integrated distribution box module to fuse devices of different sizes and specifications, thereby reducing the impact of the fuse device size on the internal space layout of the integrated distribution box module. The fuse device is fixed to the connecting strip and the notches by plugging or laser welding, which can achieve support, limiting, and electrical connection of the fuse device, reducing installation difficulty while ensuring the effectiveness and stability of the fuse device installation, improving installation accuracy, processing yield, and production efficiency.

[0054] like Figure 1 , Figure 2 As shown, the power distribution box integrated module provided in the embodiment of this application includes: a housing 100 and a safety device 200. The housing 100 is provided with a connecting bar 300, and three notches 310 are formed on the connecting bar 300. The safety device 200 includes a safety body 210 and two lead-out bars 220. The safety device 200 is inserted into the notches 310 through the lead-out bars 220 to realize the electrical connection between it and the connecting bar 300, and is fixed on the connecting bar 300.

[0055] It is understood that a connecting strip 300 is provided inside the housing 100. The connecting strip 300 acts as an adapter, enabling electrical connection between the housing 100 and internal components. Simultaneously, the connecting strip 300 has at least three recesses 310. These recesses 310 can be combined in pairs to connect one-to-one with the lead-out strips 220 of fuse devices 200 of different sizes, thus adapting to the dimensions of fuse devices 200 of varying sizes. This improves the adaptability of the distribution box integrated module to fuse devices 200 of different sizes and specifications, thereby reducing the impact of fuse device dimensions on the internal spatial layout of the distribution box integrated module. It should be noted that the connecting strip 300 is located inside the housing 100. The housing 100 can be a hollow structure without a base plate, with the connecting strip 300 serving as the base of the housing 100; it can also be a drawer-type structure with a base plate. Depending on whether the base plate can be flexibly installed and disassembled, the housing 100 can also be a fixed base plate structure or a movable mounting plate structure. Depending on the number of base plate layers, the housing 100 can also be a single-layer or multi-layer base plate structure.

[0056] It should be noted that there are no limitations on the shape and number of the connecting strip 300. A single connecting strip 300 can be connected to the lead-out strip of the safety device 200 of different sizes and specifications through a notch 310. Alternatively, at least two connecting strips 300 can be combined to define the same safety device 200. There are no limitations on the correspondence between the connecting strip 300, the number of its notches 310 and the safety device 200.

[0057] It should be noted that more than three notches 310 can be formed on the connecting strip 300, such as three, four, five, ten, etc., and there is no limit to the number of notches 310. The notches 310 can be parallel to each other or form an angle with each other, and there is no limit to the relative position between multiple notches 310. The two-dimensional projection shape of the notch 310 relative to the distribution box integrated module in the horizontal direction can be a circle, triangle, quadrilateral, polygon, star, etc., and the projection area in the thickness direction can vary depending on the thickness, etc., and there is no limit to the variation of the two-dimensional projection in the horizontal direction and the projection area in the thickness direction of the notch 310. The size of the notch can be limited by the diameter, such as diameter = 5mm, 8mm, 10mm, etc., or by the length and width, such as 2mm×2mm, 2mm×5mm, 5mm×5mm, 5mm×10mm, etc., and there is no limit to the specific shape and size of the notch 310. The distance between any two notches 310 is not limited, as long as it does not exceed the range of the housing 100 and the connecting strip 300. There is also no restriction on whether the notch 310 penetrates the entire thickness direction of the connecting strip 300. The notch 310 can be a hole that penetrates the connecting strip 300 or a slot that is not penetrating. As long as it can be engaged and connected with the lead-out strip, it falls within the protection scope of this disclosure.

[0058] like Figure 1As shown, the housing 100 has two connecting bars 300, and the two connecting bars 300 form a total of three recesses 310. The recesses 310 are arranged sequentially along the length of the distribution box integrated module, namely the first recess 311, the second recess 312, and the third recess 313. The first recess 311, the second recess 312, and the third recess 313 can be arranged in various ways. The specific combination methods of the recesses 310 are illustrated below.

[0059] In one feasible implementation, the vertical distance between the first recess 311 and the second recess 312 is 45mm-50mm, and the vertical distance between the first recess 311 and the third recess 313 is 85mm-90mm. The vertical distance between the recesses 310 is the distance between the geometric centers of the recesses 310 along the length of the distribution box integrated module.

[0060] When the length of the safety device 200 along the length direction of the distribution box integrated module is less than or equal to 50mm, the lead-out bar 220 is connected to two adjacent recesses 310, such as the first recess 311 and the second recess 312, and the second recess 312 and the third recess 313; when the length of the safety device 200 along the length direction of the distribution box integrated module is greater than 50mm, the lead-out bar 220 is connected to two spaced recesses 310, such as the first recess 311 and the third recess 313.

[0061] It is understandable that the length of the safety device 200 along the length of the distribution box integrated module can be adjusted according to the position of the notch 310, such as increasing the thickness of the lead-out bar, the length of the lead-out part, or the length of the conductive post, without any limitation.

[0062] Understandably, the number and vertical distance of the notches 310 can be adjusted according to the size variations of the safety device 200. For example, four or more notches 310 can be provided. The lead-out bar 220 can select appropriate combinations of notches 310 for connection based on the relationship between the actual size of the safety device 200 and the vertical distance between the notches 310. For example, the notches 310 connected to the lead-out bar 220 can be the first notch 311 and the second notch 312, the second notch 312 and the third notch 313, the third notch 313 and the fourth notch, the first notch 311 and the third notch 313, the second notch 312 and the fourth notch, the first notch 311 and the fourth notch, and so on. Different combinations of notches 310 can be used to connect safety devices 200 of different sizes and specifications, improving the adaptability of the distribution box integration module to the safety device 200, reducing the mold opening cost and sample production cycle of the distribution box, simplifying the internal space occupation of the battery pack, and improving production efficiency.

[0063] like Figure 2As shown, the safety device 200 includes a safety body 210 and at least two lead-out bars 220. Each lead-out bar 220 includes a lead-out portion 221 and a connecting portion 222. The lead-out portion 221 is connected to the safety body 210. The connecting portion 222 extends away from the lead-out portion 221 to form a protrusion 2221. The protrusion 2221 is connected to the recess 310 of the connecting bar 300. At least a portion of the lead-out portion 221 of the lead-out bar 220 abuts against the safety body 210.

[0064] Understandably, at least a portion of the lead-out portion 221 of the lead-out bar 220 abuts against the fuse body 210, and the connecting portion 222 forms a protrusion 2221 in the direction away from 221, which connects with the recess 310, defining the position of the fuse device 200 in the distribution box integrated module, ensuring the installation accuracy of the fuse device 200, and improving assembly efficiency.

[0065] In one specific embodiment, the portion of the lead-out part 221 that abuts against the fuse body 210 can be connected to the fuse body 210 by bolts to ensure that the lead-out part 221 and the fuse body 210 are effectively abutted, so as to prevent the fuse device 200 from shaking in the distribution box integrated module and improve the overall stability.

[0066] It is understood that the shape of the lead-out bar 220 and the protrusion 2221 can be circular, elliptical, semi-circular, triangular, rectangular, polygonal, or other regular or irregular shapes, or can be a combination of the above shapes; there are no restrictions on this. The size relationship between the lead-out portion 221 and the connecting portion 222 of the lead-out bar 220 is not restricted, nor is it required that the shape of the lead-out portion 221 and / or the connecting portion 222 be completely consistent with the shape of the safety body 210 in the width direction.

[0067] Preferably, the protrusions 2221 have different shapes and the recesses 310 have different shapes. The recesses 310 and protrusions 2221 can be matched to prevent confusion between components during assembly, and to prevent errors in assembly position, direction, and quantity, thereby improving assembly accuracy and efficiency.

[0068] like Figure 3 , Figure 4As shown, in one feasible embodiment, the safety device 200 includes a safety body 210 and at least two lead-out bars 220. The safety body 210 includes a conductive post 212, and the lead-out bars 220 include a lead-out portion 221 and a connecting portion 222. The lead-out portion 221 is connected to the safety body 210, and the connecting portion 222 extends away from the lead-out portion 221 to form a protrusion 2221. The protrusion 2221 is connected to the recess 310 of the connecting bar 300. The safety body 210 has an outlet 211, which is disposed opposite to connect to the lead-out portion 221 of the lead-out bar 220. One end of the conductive post 212 is inserted into the outlet 211, and the other end is connected to the lead-out portion 221, thereby forming a mating relationship between the outlet 211 and the lead-out portion 221.

[0069] It is understood that the shape of the outlet 211 can be circular, semi-circular, triangular, rectangular, polygonal, or other regular or irregular shapes, without limitation. The number of outlets 211 can be two, three, four, etc., without limitation. Multiple outlets 211 can be arranged opposite or adjacent to each other, that is, at least two outlets 211 are on opposite or adjacent faces of the insurance body 210. It is not required that all outlets 211 be arranged opposite each other, nor is it required that the outlets 211 arranged opposite each other be at the same height and / or the same cross-section relative to the insurance body 210.

[0070] It should be noted that the conductive post 212 can be any one or more materials such as elemental metal, metal alloy, and composite material. The length, shape, and cross-sectional area of ​​the conductive post 212 are not limited; for example, the conductive post 212 can be solid, hollow tubular, or other three-dimensional structures. The conductive post 212 only needs to match the outlet 211. The conductive post 212 serves to extend the width of the safety device 200 to correspond to the connection recess 310. There are no restrictions on whether the conductive post 212 can play a greater role as a functional component of the safety device 200, such as a component for conducting electricity and / or melting.

[0071] It is understandable that the shape, thickness, and cross-section of the card slot 2211 can be adapted to the specific design of the conductive post 212, as long as the card slot 2211 can limit the conductive post 212.

[0072] like Figure 5As shown, in one feasible embodiment, the safety device 200 includes a safety body 210 and at least two lead-out bars 220. The safety body 210 includes a conductive post 212, and the lead-out bars 220 include a lead-out portion 221 and a connecting portion 222. The lead-out portion 221 is connected to the safety body 210, and the connecting portion 222 extends away from the lead-out portion 221 to form a protrusion 2221. The protrusion 2221 is connected to the recess 310 of the connecting bar 300. The safety body 210 has an outlet 211, which is disposed opposite to each other. One end of the lead-out portion 221 is led out from the outlet 211 and connected at an angle to one end of the connecting portion 222. The other end of the lead-out portion 221 is connected to other components in the safety body 210, thereby forming a mating relationship between the outlet 211 and the lead-out portion 221.

[0073] It should be noted that the connection method of at least two lead-out bars 220 within the insurance body 210 can be either without connection points and separate, or with intermittent or continuous connection and not separate lead-out bar structure. That is, the lead-out part of the lead-out bar 220 is not connected to the other end of the connection part. There are no restrictions on the connection method of the lead-out bar 220 within the insurance body 210.

[0074] It is understood that the lead-out portion 221 and the connecting portion 222 are connected at an angle, and the connection angle can be any angle between 60° and 150°. The specific angle can be adaptively adjusted according to the height of the housing 100, the length and angle of the lead-out portion 220. That is to say, the connection angle can be adjusted according to the internal space occupied by the distribution box integrated module, and can also be adjusted according to whether the size of the safety device in the length direction of the distribution box integrated module matches the distance between the notches 310. The lead-out portion 221 and the connecting portion 222 in the two lead-out portions 220 can be designed symmetrically to ensure the stable connection of the safety device 200, or they can be designed to be connected at different angles asymmetrically according to the actual situation of the safety device 200 or the distribution box integrated module.

[0075] Preferably, the lead-out portion 221 and the connecting portion 222 are connected at a 90° angle, which can minimize the space occupied by the integrated circuit in the distribution box.

[0076] like Figure 6 As shown, in a specific embodiment, the distribution box integration module further includes a pre-charge relay 410, a pre-charge resistor 420, a high-voltage sampling component 500, and a PCB board 600 (Printed Circuit Board). The high-voltage sampling component 500 includes a sampling end 510 and a connection end 520. The sampling end 510 is connected to the connection bar 300, and the connection end 520 is connected to the PCB board 600 to achieve electrical connection. The two components, the pre-charge relay 410 and the pre-charge resistor 420, are connected to the connection bar 300 at one end and to the PCB board at the other end to achieve electrical connection.

[0077] Understandably, the sampling end 510 of the high-voltage sampling component 500 is set on the connection bar between the safety device 200 and the pre-charge relay 410 by welding, riveting or other means. After collecting voltage information, the sampling end 510 of the high-voltage sampling component 500 transmits the voltage information to the PCB board 600. Subsequently, the battery management system processes the voltage data, which can improve the monitoring of the performance of the components in the distribution box integrated module, thereby improving the safety and stability of the system.

[0078] It is understood that this application does not impose any special restrictions on the relative positions of the components in the distribution box integrated module in the horizontal direction. It only requires that, in the circuit diagram, the sampling terminal 510 is set between the fuse device 200 and the pre-charge relay 410 to collect the voltage information at the fuse device 200.

[0079] like Figure 7 As shown, in a specific embodiment, an insulating film 700 and a heat dissipation component 800 are provided below the connecting bar 300. The insulating film 700 can isolate the circuit and prevent short circuits caused by high voltage arcing or leakage current. The heat dissipation component 800 can reduce the temperature rise rate of the distribution box integrated module, thereby improving the current carrying capacity of the distribution box integrated module.

[0080] It is understandable that the insulating film 700 and the heat dissipation component 800 are located below the connecting bar 300, and there are no restrictions on the shape, size, thickness, or material of the insulating film 700 and the heat dissipation component 800; when the insulating film 700 and the heat dissipation component 800 are set at the same time, there are no special restrictions on the vertical relationship between the insulating film 700 and the heat dissipation component 800. The insulating film 700 and the heat dissipation component 800 can be laid flat and stacked separately, or they can be placed crosswise under the connecting bar 300.

[0081] It should be noted that in the embodiments of this application, the heat dissipation component 800 may include a thermal pad and / or a liquid cooling plate, and there are no limitations on the shape, size, thickness and material of the thermal pad and the liquid cooling plate; when the thermal pad and the liquid cooling plate are provided at the same time, there are no special limitations on the vertical relationship between the thermal pad and the liquid cooling plate, and the thermal pad and the liquid cooling plate may be laid flat and stacked, or they may be placed crosswise under the connecting row 300.

[0082] It is understood that the embodiments of this application can use laser welding to achieve electrical connections, or screw fixing to connect the components of the distribution box integrated module. Preferably, using laser welding can reduce the contact resistance when installing components, and can also avoid a series of abnormalities on the production line caused by missing, incorrect, or loose bolts due to reduced contact resistance, thereby improving the yield rate.

[0083] It is understood that embodiments of this application may use laser welding or PCBA (Printed Circuit Board Assembly) to assemble the circuit board to connect the components of the distribution box integrated module to the connecting bar 300, or traditional flexible wire harnesses may be used to connect the components to the connecting bar 300. Preferably, using laser welding and PCBA to connect the components can achieve automated assembly, improve assembly efficiency, and increase yield.
