Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 8, an ECU control circuit board 3 is provided on the peripheral surface of the motor 1, and a motor connector 2 of the motor 1 is connected to a connector of the ECU control circuit board 3; the ECU control circuit board 3 is connected by a plurality of control circuit sub-boards 3-1 through flexible circuit connecting boards 3-2.
The peripheral surface of the motor 1 is provided with at least 4 surfaces.
The number of the control circuit sub-boards 3-1 corresponds to the number of the peripheral surfaces of the motor 1.
The control circuit board 3-1 is attached to the peripheral surface of the motor 1.
As shown in figure 1, a motor connector 2 of a motor 1 is connected with 3 connectors led out from an ECU control circuit board 3, three-phase electricity controlled by the ECU flows into the motor 1 through the motor connector 2 when sine waves with a certain time sequence are generated, a magnetic field with a certain rotating speed is formed inside the motor 1, and the magnetic field can drive a motor shaft to rotate, so that the motor assisting force is realized.
As shown in FIG. 2, the ECU control circuit board 3 is formed by connecting 4 control circuit sub-boards 3-1 through 3 flexible circuit connecting boards 3-2, and in the use process, the 4 control circuit sub-boards 3-1 can rotate around the flexible circuit connecting boards 3-2. As shown in fig. 3, the 4 control circuit boards 3-1 are in a closed state.
As shown in fig. 4 and 5, in order to implement embodiment 1 of the present invention, the periphery of the motor 1 is formed by connecting 4 rectangles, and in the actual assembling process, since the control circuit board 3-1 in the ECU control circuit board 3 can rotate relative to the flexible board, the 4 control circuit boards 3-1 in the ECU control circuit board 3 can be assembled on the surface corresponding to the periphery of the motor 1. The ECU control circuit board 3 is ensured to have enough area for the arrangement of electronic components, and the problem of increase of the electronic components caused by redundant design (improvement of complete performance) is solved.
As shown in fig. 6, the ECU control circuit board 3, the motor 1, and the ECU cover 4 are combined together to form a driving unit. Because 4 control circuit subplates 3-1 in the ECU control circuit board 3 are connected through 3 flexible circuit connecting plates 3-2 and surround the periphery of the motor 1, the space size of the driving unit along the axial direction of the motor is greatly reduced, and the EPS can be conveniently distributed on the whole vehicle.
As shown in fig. 7 and 8, for embodiment 2 of the present invention, the periphery of the motor 1 can also be formed by connecting 5 rectangles, and correspondingly, the ECU control circuit board 3 is formed by connecting 5 control circuit sub-boards 3-1 and 4 flexible circuit connecting boards 3-2, so as to form a connection form of 5 motors and corresponding PCB control circuits, and the design concept is the same as that the periphery of the motor is a 4-sided polygon.
