The electric wire 135 is provided on the second circuit board 130, and the electric wire 135 is led out from the wire outlet hole 113. The wire outlet 113 is offset from the transformer 136. This can alleviate the electromagnetic interference phenomenon between the circuit in which the wire 135 is located and the transformer 136, and improve the electromagnetic compatibility of the driving unit 100.

Referring to fig. 2 and 3, alternatively, 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.
