The invention relates to an electric adjusting mechanism for an automobile headrest. The electric adjusting mechanism comprises a first support, a second support, a forward movement sliding block anda forward movement driving assembly. The forward movement driving assembly comprises a first driving motor, a first screw rod, a sliding sleeve, a connecting rod and a first rotating shaft. The secondsupport is rotationally arranged on the first support. The first driving motor is fixedly arranged on the second support. An output shaft of the first driving motor is in transmission connection withthe first screw rod. The first screw rod penetrates through a threaded through hole of the sliding sleeve, and the first screw rod is in transmission fit with the threaded through hole of the slidingsleeve. One end of the connecting rod is rotationally connected with the sliding sleeve, and the other end is rotationally connected with the first rotating shaft. The first rotating shaft is rotationally arranged on the forward movement sliding block. The forward movement sliding block is arranged on the first support in a sliding mode in the front-back direction. Forward movement and lifting ofthe headrest can be achieved through control of the motor, forward movement is overall forward movement, and the head fitting degree is better.
