Further, the heat conducting component is heat conducting glue or a heat conducting pad.

Further, the boss includes first boss, second boss, third boss, first boss, second boss, and the third boss sets up inboard at the base along electric vehicle controller's length direction interval.

Further, PCB circuit board upside is connected with motor binding post U, motor binding post V, motor binding post W, first boss, second boss, third boss and motor binding post U, motor binding post V, motor binding post W all are located same vertical plane.

Further, a motor wiring terminal U, a motor wiring terminal V and a motor wiring terminal W are connected to the upper side of the PCB; the projection of the motor wiring terminal W in the horizontal direction coincides with the projection of the first boss, the projection of the second boss and the projection of the third boss in the horizontal direction.

Further, first boss is located the below of motor binding post U, and the second boss is located the below of motor binding post V, and the third boss is located the below of motor binding post W.

Further, the base, the first boss, the second boss and the third boss are all made of metal materials.

The utility model has the advantages that: the boss and the heat conducting component of the base are utilized to rapidly dissipate heat of the UVW phase line on the PCB, so that the heat conducting problem of the motor controller is reduced, and the service life is prolonged.

Detailed Description

As shown in fig. 1 and 2, an electric vehicle controller 10 includes an upper cover 11 and a base 12, the upper cover 11 and the base 12 are fixedly connected by screws to form an accommodation space S1, a PCB circuit board 13 is disposed in the accommodation space S1, a boss 121 is disposed on the inner side of the base 12, a heat conduction assembly 14 is disposed between the lower side of the PCB circuit board 13 and the boss 121, the upper side of the heat conduction assembly 14 is attached to the lower side of the PCB circuit board 13, and the lower side of the heat conduction assembly 14 is attached to the boss 121. In order to further improve the heat conduction effect and buffer and insulate the PCB, the heat conduction assembly 14 may be an elastic material with good heat conduction and insulation performance, such as a heat conduction glue or a heat conduction pad. The bosses 121 include a first boss 121A, a second boss 121B, a third boss 121C, the first boss 121A, the second boss 121B, and the third boss 121C disposed at intervals inside the base 12 along the length direction of the electric vehicle controller 10.

In this embodiment, the number of the bosses 121 is not only three, but also may be four or five, and may be set according to the position and size of the motor terminal. As shown in fig. 3, the first bosses 121A, the second bosses 121B, and the third bosses 121C all have the same height. The PCB circuit board 13 upside is connected with motor binding post U151, motor binding post V152, motor binding post W153, first boss 121A, second boss 121B, third boss 121C and motor binding post U151, motor binding post V152, motor binding post W153 all are located same vertical plane V1. The upper side of the PCB 13 is connected with a motor wiring terminal U151, a motor wiring terminal V152 and a motor wiring terminal W153; the projections of the motor wiring terminal U151, the motor wiring terminal V152 and the motor wiring terminal W153 in the horizontal direction are overlapped with the projections of the first boss 121A, the second boss 121B and the third boss 121C in the horizontal direction.
