[0070] As the main direction of future automobile development, the performance and reliability of the motor control system of new energy vehicles are crucial to the power, economy and safety of the vehicle. In order to quickly iterate functions and adapt to the market, the design of new energy electric control systems is becoming more and more modular, especially the main drive module.

[0071] In the related art, the filter components, capacitor components, power modules and other devices of the main drive module are usually arranged independently, with low integration and uneven heat dissipation.

[0072] Based on the above problems, the present invention proposes a main drive module 100, aiming to improve the integration and heat dissipation uniformity of the main drive module 100. The main drive module 100 can be applied to vehicles such as new energy electric vehicles and gasoline vehicles.

[0073] See also Figures 1 to 6In one embodiment of the present invention, the main drive module 100 includes a housing 10, a filter assembly 20, a capacitor core package assembly 30, a power module assembly 40 and a three-phase plastic package assembly 50; the housing 10 has a heat dissipation channel 13, the housing 10 also has a first side 11 and a second side 12 opposite to each other, the heat dissipation channel 13 is located between the first side 11 and the second side 12, the housing 10 has an axis a passing through the center, and the heat dissipation channel 13 is mirror-symmetrical along the axis a; the filter assembly 20 is arranged on the first side 11; the capacitor core package assembly 30 is arranged on the first side 11 and is electrically connected to the filter assembly 20, and one side of the heat dissipation channel 13 is opposite to the capacitor core package assembly The power module assembly 40 is arranged on the second side 12 and is electrically connected to the capacitor core package assembly 30, and the other side of the heat dissipation water channel 13 dissipates heat on both sides of the power module assembly 40 synchronously; the three-phase plastic-coated assembly 50 is arranged on the second side 12 and is electrically connected to the power module assembly 40; wherein the shell 10, the filter assembly 20, the capacitor core package assembly 30, the power module assembly 40 and the three-phase plastic-coated assembly 50 are distributed in a leaf shape; the shell 10 is a leaf vein, the filter assembly 20 and the capacitor core package assembly 30 are conduits in the leaf vein, the power module assembly 40 is the leaf flesh in the leaf vein, and the three-phase plastic-coated assembly 50 is a sieve tube in the leaf vein.

[0074] In this embodiment, the shell 10 is like the veins in a leaf. On the one hand, it plays a role in structural support and fixation for other components. On the other hand, it can provide heat dissipation medium for transportation through the heat dissipation water channel 13 to carry away the heat generated by components such as the capacitor core package assembly 30 and the power module assembly 40 through conduction and convection, thereby reducing the operating temperature of core components, increasing their service life, and protecting the operation of the main drive module 100.

[0075] The filter component 20 and the capacitor core package component 30 are like conduits in the veins of leaves, playing the role of "filtering and transporting nutrients". The filter component 20 is responsible for limiting the passage of the allowed frequency current to meet the operating conditions without being affected by noise. The capacitor core package component 30 is responsible for smoothing voltage fluctuations and realizing the protection of the inverter. Together, they supply stable power to the power module component 40.

[0076] The power module assembly 40 , like the mesophyll in the veins of a leaf, plays the role of “converting energy”. The power module assembly 40 converts direct current into alternating current by controlling the opening and closing, which is the most critical task of the main drive module 100 .

[0077] The three-phase plastic-coated component 50 acts like a sieve tube in the veins of a leaf blade, and can output the alternating current converted by the power module component 40 to the motor, thus completing the function of "product delivery".

[0078] In one embodiment, the main drive module 100 further includes a drive control board 60, which is disposed on the second side 12 and covers the power module assembly 40 and the three-phase overmolding assembly 50. The drive control board 60 is electrically connected to the power module assembly 40; the drive board and the control board are integrated into a single board, so that it has two major functions of control and drive, and is responsible for the control and drive of the main drive module 100. Among them, a Hall chip is provided on the drive control board 60, and the Hall chip can cooperate with the magnetic core in the three-phase overmolding assembly 50, and detect the output current of the three-phase overmolding assembly 50 through the Hall effect, thereby completing the output control and abnormal monitoring of the current. In addition, the drive control board 60 is provided with a connector terminal, which is responsible for external communication control.

[0079] In this embodiment, when the heat dissipation medium flows through the heat dissipation channel 13 , it can contact the pins of the power module assembly 40 , so as to fully remove the heat generated by the power module assembly 40 during operation.

[0080] In actual application, the filter assembly 20, the capacitor core package assembly 30, the power module assembly 40, the three-phase plastic package assembly 50 and the drive control board 60 can be fixedly installed on the housing 10 by means of screw connection, riveting, clamping, welding, etc.

[0081] Furthermore, the interconnection between the output of the capacitor core package assembly 30 and the output of the power module assembly 40 can be achieved by welding, screw connection, riveting, etc. to achieve electrical interconnection and current transmission.

[0082] In summary, the technical solution of the present invention integrates the filter component 20 and the capacitor core package component 30 on the first side 11 of the housing 10, and integrates the power module, the three-phase plastic package component 50 and the drive control board 60 on the second side 12 of the housing 10, so that the filter component 20, the capacitor core package component 30, the power module, the three-phase plastic package component 50, the drive control board 60 and the housing 10 are integrated into one, and the housing 10, the filter component 20, the capacitor core package component 30, the power module component 40 and the three-phase plastic package component 50 are designed to be distributed in a leaf shape; the housing 10 is a leaf vein, and the filter component 20 The capacitor core package component 30 is a conduit in the leaf vein, the power module component 40 is the leaf flesh in the leaf vein, and the three-phase plastic-coated component 50 is a sieve tube in the leaf vein, thereby improving the integration of the main drive module 100 and obtaining a small-volume main drive module 100; in addition, since a heat dissipation water channel 13 is formed in the shell 10, when the heat dissipation medium flows through the heat dissipation water channel 13, one side of the heat dissipation water channel 13 can perform bilateral synchronous heat dissipation on the power module component 40, and the other side of the heat dissipation water channel 13 can perform uniform flow heat dissipation on the capacitor core package component 30, thereby improving the uniformity of heat dissipation of the main drive module 100.

[0083] Secondly, the three-phase plastic-coated component 50 can be a single-drive three-phase plastic-coated component 50a or a dual-drive three-phase plastic-coated component 50b to achieve switching between two output modes.

[0084] Therefore, the main drive module 100 proposed in this solution can achieve functions such as multi-stage filtering, synchronous heat dissipation, mirror temperature control, and dual-mode integration by simulating the design of plant leaves. It has strong compatibility and scalability, and can achieve both a single drive mode with low noise and high power current equalization output, and a dual drive mode with symmetrical structure and controllable output power.

[0085] See also Figure 5 In one embodiment of the present invention, the heat dissipation water channel 13 includes a first water channel 131 and a second water channel 132 symmetrically distributed along the axis a;

[0086] The capacitor core package assembly 30 is symmetrically arranged on the first side 11 of the housing 10 along the axis a, and the first water channel 131 and the second water channel 132 evenly distribute the heat to the capacitor core package assembly 30;

[0087] The power module assembly 40 is symmetrically arranged on the second side 12 of the housing 10 along the axis a, and the first water channel 131 and the second water channel 132 dissipate heat on both sides of the power module assembly 40 simultaneously.

[0088] With such an arrangement, when the heat dissipation medium flows through the symmetrically distributed first water channel 131 and the second water channel 132, the heat dissipation effect on components such as the capacitor core package assembly 30 and the power module assembly 40 can be enhanced, thereby achieving a uniform flow heat dissipation effect on the capacitor core package assembly 30 and a synchronous heat dissipation effect on both sides of the power module assembly 40.

[0089] Furthermore, the first water channel 131 and the second water channel 132 are mirror-symmetrically distributed along the axis a; the capacitor core package assembly 30 is mirror-symmetrically arranged on the first side 11 of the shell 10 along the axis a; and the power module assembly 40 is mirror-symmetrically arranged on the second side 12 of the shell 10 along the axis a.

[0090] With such arrangement, when the heat dissipation medium flows through the first water channel 131 and the second water channel 132 which are distributed in a mirror-symmetrical manner, the heat dissipation effect on components such as the capacitor core package assembly 30 and the power module assembly 40 can be further improved.

[0091] See also Figure 5 In one embodiment of the present invention, the housing 10 is further provided with a water inlet 14 and a water outlet 15 , the water inlet 14 is connected to the first water channel 131 and the second water channel 132 , and the first water channel 131 and the second water channel 132 are connected to the water outlet 15 .

[0092] With such arrangement, the heat dissipation medium enters from the water inlet 14 and is divided into two parts, respectively flowing to the first water channel 131 and the second water channel 132 , and after heat exchange with the corresponding components, they are converged and output at the water outlet 15 . In this way, only one water inlet 14 and one water outlet 15 are required, which can simplify the structural design and reduce the design cost.

[0093] See also Figure 5 In one embodiment of the present invention, the first side 11 has a first area 111 and a second area 112 that are mirror-symmetrically distributed along the axis a, the first area 111 is located on the side of the first water channel 131 away from the power module assembly 40, and the second area 112 is located on the side of the second water channel 132 away from the power module assembly 40; the capacitor core package assembly 30 includes a first capacitor core package unit 30a and a second capacitor core package unit 30b that are mirror-symmetrical and connected, the first capacitor core package unit 30a is arranged in the first area 111, and the second capacitor core package unit 30b is arranged in the second area 112.

[0094] In this way, by distributing the first capacitor core package unit 30a and the second capacitor core package unit 30b of the capacitor core package assembly 30 in a mirror-symmetrical manner in the first area 111 and the second area 112, when the heat dissipation medium flows through the first water channel 131 and the second water channel 132, heat can be exchanged with the first capacitor core package unit 30a through the heat dissipation medium flowing through the first water channel 131, and heat can be exchanged with the second capacitor core package unit 30b through the heat dissipation medium flowing through the second water channel 132, thereby achieving the effect of uniform flow heat dissipation of the capacitor core package assembly 30.

[0095] See also Figures 3 to 5 In one embodiment of the present invention, the filter component 20 is located between the first area 111 and the second area 112 .

[0096] In this embodiment, the first capacitor core package unit 30 a and the second capacitor core package unit 30 b are respectively located on two sides of the filter assembly 20 .

[0097] With such arrangement, the filter assembly 20 and the capacitor core package assembly 30 can be distributed in a leaf shape, making the distribution of components more compact and the volume smaller.

[0098] See also Figure 1 , Figure 6 In one embodiment of the present invention, the second side 12 includes a third area 121 and a fourth area 122 that are mirror-symmetrically distributed along the axis a, the third area 121 is located on the side of the first water channel 131 away from the capacitor core package assembly 30, and the fourth area 122 is located on the side of the second water channel 132 away from the capacitor core package assembly 30; the power module assembly 40 includes a first power module unit 40a and a second power module unit 40b that are mirror-symmetrical, the first power module unit 40a is arranged in the third area 121, and the second power module unit 40b is arranged in the fourth area 122.

[0099] In this way, by distributing the first power module unit 40a and the second power module unit 40b of the power module assembly 40 in a mirror-symmetrical manner in the third area 121 and the fourth area 122, when the heat dissipation medium flows through the first water channel 131 and the second water channel 132, the heat dissipation medium can exchange heat with the first power module unit 40a through the heat dissipation medium flowing through the first water channel 131, and can exchange heat with the second power module unit 40b through the heat dissipation medium flowing through the second water channel 132, thereby achieving the effect of synchronous heat dissipation on both sides of the power module assembly 40.

[0107] In this embodiment, the first power module unit 40 a and the second power module unit 40 b are respectively located on two sides of the three-phase overmolded component 50 .

[0108] With such arrangement, the three-phase overmolded assembly 50 and the power module unit can be distributed in a leaf shape, so that the distribution of components is more compact and the volume is smaller.

[0113] In actual application, the pins of the three-phase plastic package assembly 50 and the pins of the power module assembly 40 can be electrically interconnected and current transmitted by laser welding, screw connection, riveting, etc. The pins of the power module assembly 40 and the pins of the capacitor core package assembly 30 can also be electrically interconnected and current transmitted by laser welding, screw connection, riveting, etc.

[0114] See also Figure 3 , Figure 4 , Figure 7 In one embodiment of the present invention, the filter component 20 includes a positive copper column 21, a negative copper column 26, a first Y capacitor 210, a second Y capacitor 220, an X capacitor 230, a first through-hole capacitor 240 and a second through-hole capacitor 250;

[0115] The positive copper column 21 is connected to the first transfer copper bar 23 through the second filter magnetic ring 22, the first transfer copper bar 23 is connected to the first copper bar 25 through the first conductive copper column 24, and the first copper bar 25 is connected to the capacitor core package component 30; the negative copper column 26 is connected to the second transfer copper bar 27 through the second filter magnetic ring 22, the second transfer copper bar 27 is connected to the second copper bar 29 through the second conductive copper column 28, and the second copper bar 29 is connected to the capacitor core package component 30; one end of the first Y capacitor 210 is connected to the positive copper column 21, and the other end is connected to the positive copper column 21. The first through-hole capacitor 240 is connected to the housing 10; one end of the second Y capacitor 220 is connected to the negative copper column 26, and the other end is connected to the housing 10; the two ends of the X capacitor 230 are respectively connected to the positive copper column 21 and the negative copper column 26; the first conductive copper column 24 is passed through the first through-hole capacitor 240, one end of the first through-hole capacitor 240 is connected to the grounding copper sheet 260, and the other end is connected to the first copper bus 25; the second conductive copper column 28 is passed through the second through-hole capacitor 250, one end of the second through-hole capacitor 250 is connected to the grounding copper sheet 260, and the other end is connected to the second copper bus 29.

[0116] In this way, by combining the X capacitor 230, the first Y capacitor 210 and the second Y capacitor 220 with the first through-hole capacitor 240 and the second through-hole capacitor 250, a filter component 20 (multi-stage filtering) that can save structural space is formed, so that the filter component 20 itself has a symmetrical structure and is placed in the middle of the "blade", which can jointly realize a strong and effective multi-stage filtering function, and can ensure high output power while effectively extending the service life of the electrical components and the main drive module 100, and the filter component 20 can effectively limit the allowed frequency current to pass through, so as to meet the use conditions without being affected by noise.

[0117] It should be noted that the filter component 20 has a built-in filter, which is characterized by a through-hole capacitor (a first through-hole capacitor 240 and a second through-hole capacitor 250) that is a conductor passing through the center of the magnetic ring and the cylindrical film capacitor, and the conductors of the electrodes at both ends of the film capacitor are electrically interconnected with the conductor and the ground throughout the circumference.

[0119] With such configuration, the positive copper column 21 and the negative copper column 26 can be isolated from the first through-hole capacitor 240 and the second through-hole capacitor 250 by the grounding copper sheet 260, so that the positive copper column 21 and the negative copper column 26 are not subject to noise coupling, thus meeting EMC performance requirements.

[0122] See also Fig. 9 In one embodiment of the present invention, the core package negative electrode copper bar 33 is attached to the heat dissipation surface of the heat dissipation channel 13.
