[0002] The main function of a six-phase motor controller is to control and manage the operation of a six-phase motor. It utilizes power electronics, microcontroller, and sensor technologies to achieve precise motor control, ensuring efficient operation and stable output.

[0003] Currently, six-phase motors are being proposed for use in the drive field due to their advantages and safety redundancy characteristics. However, existing six-phase motors have a lot of wiring harnesses, low controller integration, and the cooling problem of the four modules is difficult to solve. Moreover, when six-phase motors are used in distributed electric drive bridge systems, two six-phase controllers are required, making control operation more complicated and the cost relatively high.

[0004] Based on the above background, a dual six-phase motor controller housing for a distributed electric drive bridge is proposed to solve the problem. Utility Model Content

The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0006] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a housing for a dual six-phase motor controller for a distributed electric drive bridge.

[0007] To achieve the above objectives, the technical solution of this utility model is: a housing for a dual six-phase motor controller for a distributed electric drive bridge, comprising: a controller housing, sealing plates installed on both the upper and lower sides of the controller housing, a partition installed inside the controller housing to divide the controller housing into an upper six-phase control system integration and a lower six-phase control system integration symmetrically, a module cover plate provided on the partition plate to form an upper water channel with the module cover plate, a lower water channel opened inside the partition plate, an inlet and an outlet installed on the left and right sides of the controller housing for water to enter and exit the upper and lower water channels respectively, and two water baffles welded on the partition plate to separate and divert the upper and lower water channels.

[0008] In some embodiments, the controller housing has a wiring terminal connected to the side, which is divided into a DC input wiring terminal and an AC output wiring terminal.

[0009] In some embodiments, there are four DC input terminals and twelve AC output terminals, all located on the same side. The six AC output terminals are arranged vertically, and the two DC input terminals are distributed on each side of the AC output terminals.

[0010] In some embodiments, the line connecting the centers of two adjacent DC input lines forms an angle of 42° with the vertical direction, and the vertical difference between the upper and lower AC output lines is 43.2 mm, with a lateral deviation of 23.5 mm.

[0011] In some embodiments, a disassembly plate is mounted on the upper side of the controller housing and near the outgoing cable end.

[0012] In some embodiments, the upper-level six-phase control system integration and the lower-level six-phase control system integration are respectively equipped with isolation walls.

[0013] In some embodiments, the partition wall is made of insulating material.

[0014] In some embodiments, the upper six-phase control system integration and the lower six-phase control system integration are equipped with bosses coated with silicone grease.

Detailed Implementation

[0032] The following detailed description of the embodiments of this utility model, in conjunction with the accompanying drawings, will provide a thorough understanding of how this utility model uses technical means to solve technical problems and achieve technical effects, enabling its implementation. It should be noted that, provided there is no conflict, the various embodiments and features within them can be combined with each other, and all resulting technical solutions are within the protection scope of this utility model.

[0033] Furthermore, numerous specific details are set forth in the following description for illustrative purposes to provide a thorough understanding of the embodiments of this invention. However, it will be apparent to those skilled in the art that this invention may be practiced without the specific details or particular methods described herein.

[0034] Please see Figure 1-6 This utility model provides a housing for a dual six-phase motor controller for a distributed electric drive bridge, comprising: a controller housing 1, with sealing plates 2 installed on both the upper and lower sides of the controller housing 1, a partition 3 installed inside the controller housing 1 to divide the controller housing 1 into an upper six-phase control system integration and a lower six-phase control system integration symmetrically, a module cover plate 4 provided on the partition 3 to form an upper water channel 5 between the partition 3 and the module cover plate 4, a lower water channel 6 opened inside the partition 3, an inlet 7 and an outlet 8 respectively installed on the left and right sides of the controller housing 1 for water to enter and exit the upper water channel 5 and the lower water channel 6, and two water baffles 9 welded on the partition 3 to separate and divert the upper water channel 5 and the lower water channel 6.

[0035] In use, the controller housing 1 is fixed to the vehicle with anchor bolts. The controller housing 1 is divided into an upper six-phase control system integration and a lower six-phase control system integration by a partition 3. This allows the controller housing 1 to be installed on both the upper and lower sides of the partition 3, enabling one controller housing 1 to accommodate two sets of six-phase control hardware systems. This allows one controller to control two six-phase motors. Cooling water is introduced into the lower water channel 6 through the inlet 7. Under the obstruction of the module cover plate 4, the cooling water is also diverted into the upper water channel 5. After being separated and diverted by the water baffle 9, the cooling water flows through the upper water channel 5 and the lower water channel 6 and then converges at the outlet 8 before being discharged from the controller housing 1. This provides heat dissipation for both sets of six-phase control hardware systems inside the housing.

[0036] According to some embodiments of this application, optionally, the controller housing 1 has output terminals connected to its side. These output terminals are divided into DC input output terminals 10 and AC output output terminals 11. There are four DC input output terminals 10 and twelve AC output output terminals 11, all located on the same side. Six AC output terminals 11 are arranged vertically, and two DC input output terminals 10 are distributed on each side of the AC output terminals 11. The four DC input output terminals 10 are used to connect four DC copper busbars, and the twelve AC output terminals 11 are used to connect twelve AC copper busbars. Being located on the same side of the controller housing 1 is equivalent to arranging both the DC busbars and AC outputs at one end, which greatly saves space, increases power density, and reduces costs. Furthermore, to further save space, the upper AC and right-side DC areas are the integrated output terminals for the upper six-phase control system, while the lower AC and left-side DC areas are the integrated output terminals for the lower six-phase control system.

[0037] Please see Figure 5 To save space, after calculation and model comparison, the line connecting the two centers of the two adjacent DC input output terminals 10 forms an angle of 42° with the vertical direction, and the vertical difference between the upper and lower AC output terminals 11 is 43.2mm and the horizontal deviation is 23.5mm. This arrangement can save the maximum space and minimize the space occupied by the output terminals.

[0038] According to some embodiments of this application, optionally, a disassembly plate 12 is installed on the upper side of the controller housing 1 and is close to the outgoing cable end. Opening the disassembly plate 12 allows for the installation of the wiring harness on the upper side of the controller housing 1, making assembly more convenient.

[0039] According to some embodiments of this application, optionally, an isolation wall 13 is installed in both the upper-level six-phase control system integration and the lower-level six-phase control system integration. The isolation wall 13 is located within the housing between the DC copper busbar and the AC copper busbar, used to separate the DC area and the AC area, and has a passive shielding function to shield signal interference.

[0040] According to some embodiments of this application, optionally, the isolation wall 13 is made of insulating material. This serves to enhance insulation, creepage distance, and electrical clearance.

[0041] According to some embodiments of this application, optionally, bosses 14 coated with silicone grease are installed within both the upper and lower six-phase control system integration layers. This offers advantages such as high heat dissipation efficiency and lower cost.

[0042] According to some embodiments of this application, optionally, the upper-layer six-phase control system integration and the lower-layer six-phase control system integration inside the controller housing 1 can respectively install two capacitors, four modules, four drive boards, two control boards, two shielding boards, twelve AC copper busbars, and four DC copper busbars, in a symmetrical manner. During installation, by opening the upper sealing plate 2 of the controller housing 1, the module cover plate 4 is placed on the partition plate 3 for installing the corresponding electronic devices of the upper-layer six-phase control system integration. After installation, the controller housing 1 is flipped over and the lower sealing plate 2 is opened to install the corresponding electronic devices of the lower-layer six-phase control system integration on the partition plate 3, so that two sets of six-phase control hardware systems can be housed in one housing.

[0043] According to some embodiments of this application, optionally, the partition 3 is made of aluminum and is integrated with the controller housing 1. This facilitates processing.

[0044] According to some embodiments of this application, optionally, the partition 3 is coated with paint to form an insulating layer. The surface of the aluminum partition 3 reacts with the paint, and the aluminum is anodized to form an insulating layer, which serves to achieve the insulation function of the partition 3.
