1 is a perspective view of a mobile phone case having a dual structure according to an embodiment of the present invention. As shown in FIG. 1, the mobile phone case 10 having a dual structure according to an embodiment of the present invention may include a lower case 100 and an upper case 200.

The lower case 100 is made of an elastic material and closely adheres to the back side of the mobile phone 20 to absorb shocks. The elastic material may be silicone or synthetic rubber, and of course any other material may be used as long as it has a buffering force. Since the lower case 100 is most preferably to protect all the shocks that may be applied to the mobile phone 20 may be in the form of covering the front of the back of the mobile phone (20).

At this time, since the lower case 100 should surround and protect the mobile phone 20, the lower case 100 may have a U-shape in which a cross section of the lower case 100 is wider than the height thereof. However, since the lower case 100 may be tightly fixed to the mobile phone 20 by the upper case 200, the lower case 100 may be fixed to the mobile phone 20 even though the cross-section is not U-shaped.

The lower case 100 may be manufactured to be coupled to the mobile phone 20 by itself, but since the lower case 100 is made of an elastic material and thus the coupling force may be reduced, the mobile phone 20 may be combined with the upper case 200. Can be fixed to the Alternatively, the lower case 100 may be coupled to the mobile phone 20 in a form to protect not only the side of the mobile phone 20 but also a portion of the front surface, and the upper case 200 may be a portion of the side of the lower case 100. Can be combined in a wrap-around form. This allows both the lower case 100 and the upper case 200 to be firmly fixed to the mobile phone 20, and at the same time, the lower case 100 and the upper case 200 on the side of the mobile phone 20 to which the present invention is coupled. This is to improve the aesthetics by exposing all appearance of). Coupling of the lower case 100 and the upper case 200 will be described in more detail with reference to FIGS. 2 to 4.

The upper case 200 is made of inelastic material and is coupled to the mobile phone 20 in such a manner as to cover the back of the lower case 100. Inelastic material refers to a rigid material such as plastic, metal, etc., while the lower case 100 is made of an elastic material, while the upper case 200 is made of an inelastic material, the lower case 100 is effective in absorbing shock. Even if the elastic material has a weak force for maintaining a constant shape, since the gap between the lower case 100 and the mobile phone 20 is formed, dust and the like may be introduced to cause scratches on the back of the mobile phone 20. to be. Therefore, the shock absorbed through the lower case 100 of the elastic material, and maintains the adhesion of the lower case 100 through the upper case 200 of the inelastic material. Through this, the present invention can exhibit two effects simultaneously, such as shock absorption and tight fixing of the case, which can be implemented because the present invention is made of a dual structure having different materials, unlike the conventional mobile phone case.

Like the lower case 100, the upper case 200 may have a U-shape in which a cross section is wider than a height, and may cover a front surface of the lower case 100. If the upper case 200 is coupled to the mobile phone 20 in such a way that covers the front of the lower case 100, not only can the contact between the lower case 100 and the mobile phone 20 is completely maintained, the lower case 100 ) Can effectively prevent contamination.

2 is a plan view and a cross-sectional view of a mobile phone case having a dual structure according to an embodiment of the present invention. As shown in Figure 2, in the mobile phone case 10 having a dual structure according to an embodiment of the present invention, the lower case 100 is formed with a groove 110 of a predetermined size on the outer surface, the upper case ( 200 is a protrusion 210 is formed on the inner surface to correspond to the groove 110, the protrusion 210 is inserted into the groove 110, the upper case 200 and the lower case 100 can be removed. Of course, in order to increase the fastening force between the upper case 200 and the lower case 100, a plurality of grooves 110 and the protrusion 210 may be configured. However, it is important to accurately correspond the positions of the grooves 110 and the protrusions 210 so that the position of the lower case 100 can be properly fixed.

At this time, by processing both the protrusion 210 and the groove 110, the user can conveniently perform the combination of the upper case 200 and the lower case 100, the protrusion 210 and the groove 110 The collision with each other can be prevented from being broken or damaged.

3 is a plan view and a cross-sectional view of a mobile phone case having a dual structure according to an embodiment of the present invention. As shown in Figure 3, in the mobile phone case 10 having a dual structure according to an embodiment of the present invention, the groove 110 of the lower case 100 in a line shape on the outer surface of the lower case 100 Is formed, the protrusion 210 formed on the inner surface of the upper case 200 may be coupled to the groove 110 in a sliding manner. In this case, the protrusion 210 may also be manufactured in a line shape, like the groove 110 of the lower case 100.

In this case, the groove 110 and the protrusion 210 used in the sliding method do not need to be curved as shown in FIG. 2. In the sliding method, since the protrusions 210 are coupled to the grooves 110 by sliding, there is no fear that the grooves 110 and the protrusions 210 may be damaged during the bonding process even if the cross section is rectangular.

In the projection insertion method as shown in FIG. 2, since the upper case 200 or the lower case 100 may be coupled to each other only to some extent, the case may be damaged. Therefore, the present invention, as shown in Figure 3, by sliding the upper case 200 and the lower case 100 can be coupled to prevent the case is unexpectedly broken in the bonding process. However, since the sliding method of FIG. 3 requires a sliding operation to be performed, it may be more cumbersome than the protrusion insertion method of FIG. 2.

In addition, in the mobile phone case 10 having a dual structure according to an embodiment of the present invention, the protrusion 210 of the upper case 200 is formed with a stepped portion 211 at the end, the groove 110 of the lower case 100 ) May have a recessed portion corresponding to the stepped portion 211, and the protrusion 210 may be fixed by the stepped portion 211 so as not to fall out of the groove 110. Since the sliding method is a method in which the lower case 100 slides in a predetermined direction along the upper case 200, the movement of the lower case 100 is completed after the coupling between the lower case 100 and the upper case 200 is completed. If not fixed, the lower case 100 can be separated from the upper case 200 by sliding. Therefore, the present invention prevents the protrusion 210 of the lower case 100 from falling out from the groove 110 by using the stepped 211, and the size of the stepped 210 is inserted into the groove 110. The movement may be prevented, but the sliding of the lower case 100 should not be impossible.

When using the sliding method shown in FIG. 3, the upper or lower end of the upper case 200 should be open so that the lower case 100 can be inserted. If the side of the upper case 200 interferes with the insertion of the lower case 100, since the lower case 100 should be bent in a curved state for coupling with the upper case 200, the lower case 100 may be broken. Because there is. In addition, the end of the protrusion 210 of the open portion can be made to be in a slanted shape so that the lower case 100 is smoothly sliding to the upper case 200.

4 is a cross-sectional view of a mobile phone case having a dual structure according to an embodiment of the present invention. As shown in Figure 4, the lower case 100 and the upper case 200 of the mobile phone case 10 having a dual structure according to an embodiment of the present invention, the magnetic member 120, which is provided on the side or back 220 may be combined. If the magnetic members 120 and 220 are used, the process of fitting the protrusion 210 to the groove 110 or the sliding process of the lower case 100 is not necessary, so that the user can combine the case more conveniently. In this case, the magnetic members 120 and 220 may be formed in plural on the entire side, a part of the side, and a part of the rear surface. If the upper case 200 is made of a metallic material, the magnetic members 120 and 220 only in the lower case 100. ) Will be sufficient.

Of course, the present invention can be used in combination with the magnetic member method in Figure 4, the projection insertion method in Figure 2 or the sliding method in FIG. This is to eliminate the risk of losing the upper case 200 or lower case 100 by further strengthening the coupling force of the case.

5 is a plan view of a mobile phone case having a dual structure according to an embodiment of the present invention. As shown in Figure 5, the upper case 200 of the mobile phone case 10 having a dual structure according to an embodiment of the present invention, a hole 230 to expose a portion of the lower case 100 on the back Is formed, the lower case 100 may be a picture 130 is formed in a portion corresponding to the hole 230. Since the present invention has a dual structure, the appearance of the mobile phone 20 can be decorated by utilizing the characteristics of the dual structure. That is, while the picture 130 shown in the lower case 100 is exposed through the holes 230 of the upper case 200, the picture 130 is changed according to the coupling direction of the lower case 100. It will be described in detail below.

In the mobile phone case 10 having a dual structure according to an embodiment of the present invention, the hole 230 of the upper case 200 is formed in a portion spaced a predetermined distance from the center of the back of the upper case 200, The picture 130 of the case 100 is composed of a plurality of, and according to the coupling direction of the lower case 100 and the upper case 200 may be such that only one picture 130 is exposed through the hole 230. The hole 230 is not formed in the center portion of the back side, because when the hole 230 is formed in the center portion of the back side, the same figure 130 is inevitably exposed even if the coupling direction of the lower case 100 is changed. . That is, the present invention is characterized in that the user can arbitrarily change the appearance of the present invention as the user adjusts the coupling direction of the lower case 100, the hole 230 of the upper case 200 is constant from the center of the back It is preferred to be spaced apart. In this case, a plurality of holes 230 may be provided.

Since the plurality of pictures 130 displayed on the lower case 100 are exposed through the holes 230 of the upper case 200, they may be formed in consideration of the size of the holes 230. This is because a portion larger than the hole 230 in the picture 130 cannot be exposed to the outside. At this time, the picture 130 is composed of two different sets of pictures 130, by changing the coupling direction of the lower case 100 by 180 degrees to change the picture 130 exposed to the hole 230, the upper case 200 may have an exterior decoration 230 connected to the picture 130 exposed through the hole 230 on the back side. As shown in FIG. 5, when the lower case 100 is coupled to the upper case 200 in a predetermined direction, the person shape displayed on the back of the upper case 200 is completed as a person who holds the moon with a smile. . On the other hand, when the lower case 100 is coupled to the upper case 200 in the opposite direction, the person shape displayed on the back of the upper case 200 becomes a person holding the sun with a sullen face. Therefore, the present invention has the effect that the appearance of the upper case 200 is changed according to the direction of the lower case 100, the user can freely change the aesthetics of the mobile phone 20 by arbitrarily changing the appearance of the present invention.

As such, the present invention is manufactured by using a double structure of the case, but by using a combination of the upper case 200 and the lower case 100 made of different materials, due to the impact generated in the conventional mobile phone case consisting of only one material All problems such as breakage and dust inflow can be solved, and the user's satisfaction can be greatly improved by allowing the user to arbitrarily change the appearance according to the coupling direction of the lower case 100.

In addition, the mobile phone case 10 having a dual structure according to an embodiment of the present invention, made of a magnet on the back of the upper case 200, one or two earphone fixing part to be detachable to the end of the earphone (not shown) May not be formed). Recently, smartphones that are widely used include MP3 functions and are used as MP3 players for users. In this case, the earphone is generally used to connect the earphone. When the earphone is inserted into the earphone terminal of the smartphone, since the length of the earphone mainly exceeds 1 m, the end of the earphone hits the ground, which may damage the earphone. That is, when the earphone is inserted into the smartphone, the end of the earphone fixed to the user's ear moves freely, so that the end of the earphone falls to the floor and is damaged unless the smartphone is positioned at a height of 1 m or more from the ground. Therefore, the present invention provides a magnet earphone fixing part on the back of the upper case 200, so that the user can keep the end of the earphone attached to the upper case 200 to prevent damage to the earphone. . This is because earphones, which are small speakers, contain magnets or metals therein.

In this case, if only one earphone fixing part is formed, both ends of the earphone can be manufactured to a size that can be attached, and if two earphone fixing parts are formed, each end of the earphone can be manufactured in a size corresponding to each other. In addition, the earphone fixing portion may be provided on the upper back of the upper case 200 in the form of a dumbbell or a circle.
