The invention discloses an automobile headrest structure for neck protection after rear-end collision. The automobile headrest structure comprises a cylinder, a control module and a frame; the frame is arranged within the headrest in a sliding manner; a supporting block is arranged on an open end of the frame; the supporting block is connected with an output end of the cylinder; an adjusting rod is mounted on an end portion, opposite to the output end, of the cylinder; one end of the connecting rod is hinged to the adjusting rod; a movable block is mounted on the other end of the connecting rod; two trapezoidal grooves are formed in an inner sidewall, directly facing the adjusting rod, of the frame; a cavity is formed within the supporting block and filled with an elastic rubber; a cambered contact surface is arranged on a sidewall of one side, far away from the output end of the cylinder, of the supporting block. When a distance of a 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 supporting block to move backwards, so that the supporting block returns, and therefore, no manual operation is required and synchronization of headrest protection and the automobile safety system is realized; besides, a reliability coefficient of automobile driving safety is enhanced.
