The invention discloses a using method of an active headrest for protecting safety of the neck of an automobile passenger. The using method includes the following steps that firstly, a control module electrically connected with an air cylinder is directly communicated with an automobile active safety system; when the distance between a vehicle located behind an automobile and the automobile is within a dangerous value range, the control module directly transmits a command to the air cylinder, the output end of the air cylinder stretches out, and a head plate is driven to move forwards, so that the supporting part of the headrest gets close to the head of the passenger, the backward movement, relative to the upper trunk, of the head is limited in advance when rear-end collision happens, it is avoided that the air cylinder is not started in time when the collision happens, and consequently whiplash injuries are caused; and when the distance between the vehicle located behind the automobile and the automobile is within a safe value range, the control module directly controls the air cylinder to retract back, in other words, the output end of the air cylinder drives the head plate to move backwards, and the head of the passenger and the supporting part of the headrest can reset. No manual operation is needed, and synchronization of headrest protection and the automobile safety system is achieved.
