Description

  The present invention relates to a portable terminal provided with a cover component that can be attached to a portable terminal body.

  Unlike a terminal body that connects two housings in a foldable or slidable manner, the body of a mobile terminal such as a smartphone (multi-function mobile phone) is a substantially flat or simple flat cuboid. It is often formed with. Therefore, most of the area in front of the terminal body is occupied by a display unit that also serves as a touch operation unit.

  As for the appearance of such a mobile terminal body, there are few elements that can be differentiated in design from other mobile terminals. However, in recent mobile phones, market competition is fierce, and it is necessary to differentiate products in order to win market competition.

  For this reason, a portable terminal has been proposed in which a cover called a “jacket” can be attached to the back and side surfaces of the casing so that the user can customize the portable terminal to a desired shape and color.

  Note that Patent Documents 1 to 3 disclose a mobile terminal to which a cover can be attached to protect the mobile terminal body.

  Since the display unit on the front surface of the terminal main body such as the smartphone described above is always exposed on the surface of the housing, the display unit is easily damaged when the mobile terminal is dropped on the floor or the ground.

  Since the jacket described above is attached to the back and side surfaces of the mobile terminal body, it is possible to protect the back and side surfaces of the housing, but there is a problem that the front display portion that is easily damaged is not protected.

  Therefore, in view of the above-described background art, the present invention provides a structure that allows a cover component to be mounted on a mobile terminal body so that the display unit can be protected along with decoration of the mobile terminal body such as a smartphone.

  One aspect of the present invention relates to a mobile terminal including a mobile terminal body having a substantially rectangular flat plate shape and a cover component that can be attached to the mobile terminal body.

  The feature of the mobile terminal in this aspect is a surface having the maximum area on the front and back surfaces of the mobile terminal body, and the left side surface and the right side surface of the mobile terminal body are formed along the long side direction of each side surface. 1 groove.

  Further, the cover parts are arranged on three sides of one cover wall formed in a substantially quadrilateral shape in accordance with the front and back surfaces of the mobile terminal body and four sides of the outer periphery of the cover wall. It consists of a 1st, 2nd and 3rd side wall.

  Each of the first and second side walls is opposed to two of the three sides so as to correspond to the left side surface and the right side surface of the mobile terminal body when the cover part is attached to the mobile terminal body. It is provided along each side.

  The third side wall corresponds to one of the remaining two opposite top and bottom surfaces excluding the left side and right side of the mobile terminal body when the cover part is mounted on the mobile terminal body. It is provided along the remaining one side excluding the two sides of the cover wall.

  First protrusions that are engaged with the first grooves on the left side surface and the right side surface are formed on the inner side surfaces of the opposing first and second side walls, respectively. Each of the first protrusions is located in the vicinity of the end of the inner surface of the first and second side walls opposite to the third side wall.

  Further, the peripheral surface of the first protrusion includes two planes parallel to the long sides of the first and second side walls and two convex curved surfaces connecting the two planes. The width between the flat surfaces of the first protrusion is smaller than the width of the first groove, and the maximum width between the convex curved surfaces of the first protrusion is larger than the width of the first groove.

  The end of the first groove on either the top surface or the bottom surface is provided with a recess used as a rotation bearing for the first protrusion.

  According to the present invention, when the mobile terminal is used, the first wearing state that covers the back and sides of the mobile terminal main body, and when the mobile terminal is not used (when standing by the phone, carrying it, etc.), the front and side are covered. The second mounting state can be changed without removing the cover part. In other words, by engaging the projections on the inner side surfaces of the two opposite side walls of the cover component with the first grooves on the left and right side surfaces of the mobile terminal body, the cover part is slid and moved to the recess at the end of the first groove. Since the component can rotate with respect to the mobile terminal body around the first protrusion, the first mounting state and the second mounting state can be freely switched. Therefore, the front display unit can be easily protected together with the decoration of the mobile terminal body.
