The wireless charging may be implemented by a magnetic induction method or a resonance method (magnetic resonance method).

However, there is a problem that the case can not be separated from the uni-body type case and the battery can not be replaced. In order to provide a uni-body capable of replacing a battery, the present invention comprises two bodies in which the upper and lower sides are separated by dividing a position where the resin part 1022 and the metal part 204 are in contact with each other.

FIG. 2 is a view showing a state in which the first body 100 and the second body 200 of the mobile terminal of the present invention are separated. FIG. 3 is a view showing a state in which the second body 200 and the battery 191 are separated Fig.

The second body 200 may be positioned on the upper side of the display unit 151 while the second body 200 is positioned on the lower side of the display unit 151. [

One side of the first body 100 is opened and the other side is closed and the battery accommodating portion in which the battery 191 is inserted is exposed through one side of the first body 100. The first body 100 includes an integrated case 102 in which the left and right side surfaces and the rear surface of the mobile terminal 10 form continuous surfaces. The case 102 of the unibody type in which the side surface and the back surface form a continuous surface has an advantage that a more clean appearance can be provided.

The second body 200 is coupled to one side of the first body 100 so that the first body 100 and the second body 200 form a bar-shaped mobile terminal 10. The front surface of the mobile terminal 10 is the lower portion of the display portion 151 and the rear surface is the lower portion of the resin portion 1022 described above.

Even when a case of a metal body having a uni-body is provided, a part where another member such as the display unit 151 is disposed is bounded, and when the resin part 1022 is included for antenna performance, The boundary between the first body 100 and the second body 200 may be positioned at the boundary so that a boundary portion may not be additionally formed.

[ 2, the fixing protrusion 220 is fixed to the second body 200 and the fixing protrusion 220 is inserted into the battery fixing groove 225 formed in the battery 191. As shown in FIG. The end of the fixing protrusion 220 is semicircular and the fixing groove 225 is formed in a semicircular shape so that when the fixing protrusion 220 is pressed, the fixing protrusion 220 is pushed to be coupled to the fixing groove 225 or separated from the fixing groove 225 .

Since the fixing protrusion 220 is pushed when a predetermined force is applied and then returned to its original position, a material having a predetermined elasticity can be used. For example, if a synthetic resin is used, the shape of the part may change, and the part may be caught in the fixing groove 225 and then be removed. The fixing protrusion 220 may have a separate fixing structure to stably engage with the second body 200 because the shape of the fixing protrusion 220 is repeatedly applied due to the battery change. That is, an L-shaped fastening structure other than the protrusions that engage with the fixing grooves 225, and may be formed in an F-shape as shown in FIG.
