Electronic device with screen protector

An electronic device, comprising:

• a shell;
• a screen mounted in the shell;
• a screen protector connected to the shell and arranged at a periphery of the screen, an inner surface of the screen protector contacts with an outer side surface of the screen, the screen protector is configured to stretch or retract relative to the screen such that the screen protector moves between a stretchable state and a retractable state;
• a controller, received in the housing and electrically connected with a sensor, the controller is configured to control the screen protector to stretch relative to the screen along a direction substantially perpendicular to the screen to be in the stretchable in response to an output of the sensor, such that the screen protector protrudes relative to the screen to protect the screen;
• a plurality of first permanent magnets mounted on the housing;
• a plurality of second permanent magnets mounted on the screen protector and arranged opposite to the plurality of first permanent magnets;
• and
• at least one motor connected to the plurality of first permanent magnets, wherein the at least one motor is configured to drive the plurality of first permanent magnets to rotate to change directions of magnetic fields generated by the plurality of first permanent magnets, so as to switch the screen protector between the stretchable state and the retractable state.

An electronic device, comprising:

• a shell;
• a screen mounted in the shell;
• a screen protector connected to the shell and configured to stretch or retract relative to the screen such that the screen protector moves between a stretchable state and a retractable state, wherein when the screen protector is in the retractable state, the screen protector is leveled with or below the screen, and when the screen protector is in the stretchable state, the screen protector is above the screen;
• a drive assembly, comprising a first magnetic component and a second magnetic component arranged opposite to the first magnetic component, wherein the first magnetic component is received in the housing, the second magnetic component is received in the screen protector, the drive assembly is configured to drive the screen protector to move between the stretchable state and the retractable state by magnetic force;
• a controller, received in the shell and electrically connected with a sensor, the controller is configured to control the drive assembly to drive the screen protector to move between the stretchable state and the retractable state in response to an output of the sensor;
• and
• a plurality of locking mechanisms between the at least one screen protector and the housing to buckle the at least one screen protector with the housing;
• wherein the housing defines a plurality of grooves along a circumference thereof, the at least one screen protector surrounds the at least one screen and defines a plurality of slots arranged along a circumference thereof, the plurality of grooves and the plurality of slots have a one-on-one correspondence, each of the grooves is communicated with a corresponding slot, the housing has a bottom inner surface in the groove;
• each of the locking mechanisms comprises:
• a latching portion arranged on the at least one of the screen protector;
• a hook comprising a main body arranged in the groove and contacting with the bottom inner surface and a hook body engaged in the corresponding slot and matching with the latching portion;
• and
• a supporting portion arranged on the housing and in contact with the latching portion such that the latching portion is located between the hook body and the supporting portion.
