The wire 135 is provided on the second circuit board 130, and the wire 135 is led out from the wire outlet hole 113. The wire outlet hole 113 and the transformer 136 are staggered. In this way, the electromagnetic interference phenomenon between the circuit where the wire 135 is located and the transformer 136 can be alleviated, thereby improving the electromagnetic compatibility performance of the driving unit 100.

[0041] Combination Figure 2 and Figure 3 Optionally, the bracket 110 includes a mounting plate 111 and a side plate 112, and the first circuit board 120 is connected to the mounting plate 111. The side plate 112 is connected to the side of the mounting plate 111 away from the first circuit board 120, and the second circuit board 130 is connected to the end of the side plate 112 away from the mounting plate 111. The side plate 112 is provided with a wire outlet hole 113. It can be understood that the wire outlet hole 113 and the transformer 136 are staggered, that is, the center line of the wire outlet hole 113 and the center line of the transformer 136 are not on the same cross section of the bracket 110.

[0042] In this embodiment, in order to increase the distance between the wire 135 and the transformer 136 as much as possible and improve the electromagnetic compatibility, the projection of the wire outlet 113 on the side plate 112 and the projection of the transformer 136 on the side plate 112 do not overlap.

[0043] Of course, in some embodiments, one of the wire 135 and the transformer 136 is disposed in the middle of the second circuit board 130, and the other is disposed at the edge of the second circuit board 130.

The wire 135 includes a live wire and a neutral wire, and the live wire is electrically connected to the L-pole socket 142, and the neutral wire is electrically connected to the N-pole socket 143. In this way, the drive unit 100 is electrically connected to the socket module 140, and the socket module 140 can be used to supply power to the drive unit 100.
