The invention discloses an electronic device comprising a housing assembly; a display assembly; a protection member, wherein the protection member is movably disposed on the housing assembly between aretracted state and an extended state, the protection member extends the appearance surface of the display assembly in the extended state, and the protection member is flush with or lower than the appearance surface of the display assembly in the retracted state; and a movable connection assembly, wherein the movable connection assembly comprises a clamping hook, rolling members, a first elasticportion and a second elastic portion, on the direction of expansion and contraction of the protection member, the first elastic portion often drives the clamping hook to push the protection member tomove toward the retracted state, and on the direction of expansion and contraction vertical to the protection member, the second elastic portion often pushes the clamping hook to abut against the protection member, and the rolling members are respectively provided among the clamping hook, the first elastic portion and the second elastic portion. The electronic device disclosed by the invention canprevent the display assembly from being damaged, improve the aesthetics of the electronic device, reduce the friction between the housing assembly and the protection member, and increase the effective efficiency of the repulsive force generated by first and second magnets.
