The invention discloses an application method of an automobile active headrest structure for neck protection. The application method comprises the following steps: firstly, a control module electrically connected with a cylinder is directly communicated with an automobile active safety system; when a distance of a vehicle behind the present automobile to the present automobile is within a dangerous value range, the control module directly transmits a command to the cylinder so that an output end of the cylinder stretches to drive a head plate to move forwards, leading to that a supporting portion of the headrest gets close to the head of a passenger, and therefore, the backward movement of the head relative to the upper trunk is restrained in advance during rear-end collision and a whiplash injury caused by a failure of the cylinder in immediate starting when collision occurs is avoided; when a distance of the vehicle behind the present automobile to the present automobile is within a safe value range, the control module directly controls the cylinder to retract and then the output end of the cylinder drives the head plate to move backwards, so that the head of the passenger and the supporting portion of the head rest return, and therefore, no manual operation is required and synchronization of headrest protection and the automobile safety system is realized.
