Abstract
A mobile device includes a main body having a coupling element mounted thereon, and an expansion module electrically connected to the main body, wherein the expansion module comprises a magnet disposed to apply a magnetic force to the coupling element to couple the expansion module with the main body, and a movement converter configured to move the magnet away from the coupling element so as to decrease the magnetic force between the coupling element and the magnet thereby decoupling the main body from the expansion module.
Claims24
A mobile device comprising:
- a main body having a coupling element mounted thereon;
- and
- an expansion module electrically connected to the main body,
- wherein the expansion module comprises:
- a magnet disposed to apply a magnetic force to the coupling element to couple the expansion module with the main body;
- and
- a movement converter configured to move the magnet away from the coupling element so as to decrease the magnetic force between the coupling element and the magnet thereby decoupling the main body from the expansion module.
An expansion module for a mobile device comprising:
- an expansion body detachably coupled to one surface of the mobile device;
- a magnet disposed at the expansion body to apply a magnetic force to a coupling element in the mobile device thereby coupling the expansion body with the mobile device;
- and
- a movement converter configured to move the magnet away from the coupling element so as to decrease the magnetic force between the coupling element and the magnet thereby decoupling the mobile device from the expansion body.
An expansion module for a mobile device comprising:
- a first coupling element configured to be coupled to a second coupling element disposed at the mobile device;
- and
- a manipulation member configured to decouple the first coupling element and the second coupling element by converting a linear motion of the manipulation member to a rotary motion of the second coupling element.
