7 is an exploded perspective view of a detachable mobile terminal according to another example of the present application. 8 is a combined perspective view of a detachable mobile terminal according to another example of the present application.

The detachable mobile terminal according to another example of the present application further includes a slide-type detachable unit 133 for attaching and detaching the second terminal.

The slide-type detachable unit 133 is disposed on the front area in which the second terminal 200 is inserted or coupled from the first terminal 100 . 7 and 8 illustrate a case in which two slide-type detachable parts 133 are symmetrically disposed with respect to the center line of the front area of the first terminal 100 . However, the present invention is not limited thereto, and at least one slide-type detachable unit 133 may be formed on the front area of the first terminal 100 in a direction in which the second terminal slides into it.

A slider having a shape corresponding to the slide-type detachable part 133 may be formed on the rear surface of the second terminal 200 . For example, when the slide-type detachable part 133 is a groove, the slider part may be a protrusion-type protrusion. As another example, when the slide-type detachable part 133 is a rail, the slider part may be a wheel or a spherical protrusion. The second terminal 200 may be coupled or separated from the first terminal 100 with the second display unit 210 exposed to the front by the slide-type detachable unit 133 .

As a method of physically coupling the first terminal 100 and the second terminal 200 , various methods other than insertion, magnetic hinge coupling, and slide may be applied.

A detachable mobile terminal according to the present application is a connected device that can freely select a detached state and a combined state. The detachable mobile terminal according to the present application may provide various user interfaces (UI) and user experiences (UX) utilizing a display while using the second terminal 200 as a separate portable communication device. . In addition, the detachable mobile terminal according to the present application can expand the area used through platformization of individual devices, and satisfy various needs of users regarding functions, sizes, and additional functions.

Those skilled in the art from the above description will be able to see that various changes and modifications are possible without departing from the technical spirit of the present invention. Accordingly, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
