Detailed Description
The invention is further illustrated below 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 surface 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, 3 joints that motor 1's motor joint 2 and ECU control circuit board 3 were drawn forth link to each other, and the three-phase electricity of ECU control flows in for motor 1 through motor joint 2 when with certain chronogenesis sine wave, will form the magnetic field of certain rotational speed in motor 1 inside, and this magnetic field can drive the motor shaft and rotate to realize the motor helping hand.
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 embodiment 1 of the present invention, the periphery of the motor 1 is formed by connecting 4 rectangles, and in the actual assembly 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 corresponding surface of 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 drive unit in the present invention. 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, in embodiment 2 of the present invention, the periphery of the motor 1 may also be formed by connecting 5 rectangles, and correspondingly, the ECU control circuit board 3 is also 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 a 5-plane motor and a corresponding PCB control circuit, and the design concept is the same as that the periphery of the motor is a 4-sided polygon.
