<p>A protective shell (1) of an electric device which can convert kinetic energy into potential energy, it has a shell (10) and plural bounce pieces (20). Wherein, the shell (10) has a room (13) used to accommodate the electric device A; the bounce pieces (20) situate the corresponding corner of the shell (10), the outer surface including the plural bounce pieces (20) protrudes every side (121) of the shell (10) , and has a rebound rate greater than 40%. Therefore, the protective shell can avoid direct impact force to the shell side, slow impact force the electric device to withstand from the corner, and it has the advantages of shock absorption and /or damping function, thus effectively reducing the situation that the electric device damaged by external impact.</p> |
