the input interface, the first output interface, the second output interface and the shunt copper bar assembly;

the current flowing into the input interface is shunted by the shunt group copper bar assembly, and the shunted current flows into the motor controller through the first output interface and the second output interface respectively.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In the specific implementation process, the shunt filter box introduces the direct current input by the battery through the input interface 110, then shunts one path of direct current into two paths of direct current through the shunt group copper bar assembly 140, and then transmits the direct current to the two motor controllers through the first output interface 120 and the second output interface 130 respectively, so that the shunt function of changing one path into two paths is realized. If a single motor is used, only any one end of the direct current interface can be used, and the other end of the direct current interface is plugged through the cover plate, so that the compatibility of the single motor controller and the double motor controller is realized.

Specifically, the first output interface 120 and the second output interface 130 have sealing surfaces, and four corners of the housing of the shunt filter cartridge are respectively provided with mounting holes 170. The motor controller and the shunt filter box can be sealed in a radial sealing mode, and then the filter and the motor controller can be fixedly connected through the four mounting holes 170. In addition, the four mounting holes 170 are arranged in central symmetry with the first output interface 120 and the second output interface 130, so that a double-motor controller with two outgoing lines formed by assembling one shunt filter box and two identical motor controllers can be realized, and the double-motor controller is particularly suitable for coaxial double motors. Of course, one output interface can be connected with one motor controller, and the other output interface is plugged by the cover plate, so that the compatibility of the single motor controller and the double motor controller is realized.

As shown in fig. 2, fig. 3, fig. 4 and fig. 5, four controller assemblies, which are respectively a shunt filter box 1 and a single motor controller 2, are realized only by changing the installation mode, and since the installation point and the direct current interface of the shunt filter box are both designed in central symmetry, the following can be realized: the two single motor controllers 2 and the shunt filter box 1 are assembled, can be assembled into two double motor controller postures with forward and backward outgoing lines, and are particularly suitable for being integrated with coaxial double motors into an electric drive assembly, and the two outgoing line modes of the assembly are very suitable for the arrangement of front and rear drives of a whole vehicle.

Due to the special design of the shunt filter box, a plurality of products can be assembled by only using one set of single motor controller and one set of shunt filter box, so that the product generalization and the platform are effectively realized, and the cost can be effectively reduced.

Further, the shunting filter box is provided with a filtering component. When the filter assembly is used in the double-motor controller, the filter assembly can filter the two motor controllers simultaneously, and when the filter assembly is used in the single-motor controller, the filter function of the single-motor controller can be realized.

In a specific implementation process, as shown in fig. 1 and 6, the filtering component includes: a first capacitor assembly 101, a second capacitor assembly 102 and a magnetic ring 103; the first capacitor assembly 101, the second capacitor assembly 102 and the magnetic ring 103 form a pi-shaped circuit. The motor controller can be input with more stable direct current, so that the motor controller is controlled more accurately, and the performance of the device is improved. Specifically, the first capacitor assembly 101 is two capacitor components, and the second capacitor assembly 102 is three capacitor components.

Further, the shunt copper bar assembly 140 in the shunt filter box is of a laminated structure so as to reduce stray inductance.

Further, the casing of reposition of redundant personnel filtering box is equipped with radiating fin, just radiating fin is located reposition of redundant personnel copper bar subassembly from top to bottom.

In the specific implementation, as shown in fig. 6, 7 and 8, the heat dissipation fins include heat dissipation fins 105 under the housing and heat dissipation fins 104 on the upper cover of the housing. After the assembly, the bosses of the radiating fins 105 and the radiating fins 104 are directly attached to the upper surface and the lower surface of the shunting copper bar 140 through the insulating heat conducting pads, the heat of the copper bar is dissipated through the fins, the heat dissipation of the copper bar is realized, the mode can isolate the heat, and the temperature of the cavity of the motor controller is prevented from rising.
