The invention discloses an induction seat headrest structure comprising a headrest fixing portion, a headrest moving portion, a headrest moving portion drive mechanism, a longitudinal movement triggering switch, a distance detection sensor and a control module. In the instant of the vehicle rear-end collision, a collision sensor of the vehicle outputs a collision signal to the control module, the control module transmits a measurement requiring signal to the distance detection sensor, and the distance detection sensor detects the space between a driver or passenger and the headrest moving portion and returns to the control module; the control module calculates the distance for the headrest moving portion moving forward as required according to the distance detection signal, the headrest moving portion drive mechanism drives the headrest moving portion to move forward by determined distance rapidly, the headrest moving portion moves in place before the head of the driver or passenger moves to the determined position, the support on the head of the driver or passenger is provided during the rear-end collision, and the damage on the neck of the driver or passenger is reduced.
