The invention provides a protrusion crumpling energy absorption structure which comprises a circuit board, a button device, an instrument board and a rear cover. A bottomless groove is formed in the instrument board, the bottomless groove is fixedly connected with the circuit board, and the button device is fixed at the position, corresponding to the bottomless groove, of the circuit board. A first supporting wall is arranged between the circuit board and the instrument board, and a second supporting wall is arranged between the circuit board and the rear cover. Moreover, the distance between the first supporting wall and the bottomless groove is larger than the distance between the second supporting wall and the bottomless groove, and the gap between the second supporting wall and the button device is a safety crack position. According to the protrusion crumpling energy absorption structure, the problem that the crumpling energy absorption structure can not be completely cracked under the conditions that the crumpling energy absorbing structure is borne by the same external force and the set width of the crumpling energy absorption structure is large is solved.
