1. A drive apparatus, comprising a fixed assembly, a carrier, and an electrically driven assembly;
wherein a first end of the electrically driven assembly is connected to the fixed assembly, and a second end of the electrically driven assembly is connected to the carrier; and
the carrier is used for carrying a function device; and
wherein in a case of applying a voltage to the electrically driven assembly, the electrically driven assembly deforms to drive the carrier to move;
wherein the electrically driven assembly comprises electrically drive pieces, first ends of the electrically drive pieces are connected to the fixed assembly, and second ends of the electrically drive pieces are connected to the carrier;
wherein the fixed assembly comprises an annular structure member with a first through hole, the carrier is disposed in the first through hole, there are a plurality of electrically drive pieces, and the plurality of electrically drive pieces are symmetrically disposed with respect to a central axis of the first through hole;
wherein the drive apparatus comprises a housing, wherein the annular structure member is fixedly disposed at the housing, the fixed assembly further comprises a fixed member, the fixed member is disposed at an inner wall of the first through hole, and the number of the fixed members is the same as the number of the electrically drive pieces, and each of the electrically drive pieces is connected to the annular structure member through one of the fixed members;
wherein the fixed member comprises an upper gasket and a lower gasket, and the upper gasket and the lower gasket are respectively in contact with a first surface and a second surface of the electrically drive piece;
wherein the drive apparatus further comprises a circuit board, wherein the circuit board is disposed at a gap between the housing and the annular structure member, and the fixed member is electrically connected to the circuit board, and wherein in a case that the fixed member is electrically conducted with the circuit board, polarity of voltages applied to the upper gasket and the lower gasket is opposite, so that polarity of voltages applied to the first surface and the second surface of the electrically drive piece is opposite, so as to deform the electrically drive piece to drive the carrier to move.
