The utility model provides a lens focusing assembly, a camera module and electronic equipment. The lens focusing assembly comprises a first lens mounting seat, a shell and a displacement detection device. The displacement detection device adopts a magnetic sensor and three magnetic pieces (detection magnetic assemblies) to carry out position detection. Wherein the polarities of the magnetic poles on the two sides of each of the first magnetic piece and the third magnetic piece in the second direction are opposite, and the polarities of the magnetic poles on the two sides of the second magnetic piece in the first direction are opposite. And the polarity of the second magnetic piece close to the first magnetic piece and the third magnetic piece is the same as the magnetic pole polarity of the sides, facing the shell, of the first magnetic piece and the third magnetic piece. When the magnetic sensor fixedly arranged on the shell translates relative to the detection magnetic assembly fixedly arranged on the first lens mounting seat, the position of the corresponding magnetic field intensity peak value is farther away from the second magnetic piece, so that the effective detection stroke of the displacement detection device is effectively increased, and the cost is reduced.
