  Hereinafter, a configuration, operation, and effects of a portable terminal according to a preferred embodiment will be described in detail with reference to the accompanying drawings. In the description, the same components are denoted by the same reference numerals, and redundant description is omitted.

FIG. 1 is an overall perspective view of a portable terminal case according to an embodiment of the present invention.
A portable terminal case 100 according to an exemplary embodiment covers a portable terminal 10 including a tablet, a smartphone, and a notebook computer as shown in FIG. 120 and the second cover 140, and a connecting portion 160 that rotatably couples one side surface of the first cover 120 and one side surface of the second cover 140.

  Here, since the first cover 120 is not formed with grooves, protrusions, or the like, the first cover 120 covers the display of the portable terminal 10 or a portion that is vulnerable to an impact around the liquid crystal of the portable terminal 10. The cover 140 may cover the back surface of the portable terminal 10 or a portion that is resistant to impact.

  In addition, the first cover 120, the second cover 140, and the connection unit 160 may be a light, elastic or metallic metal, a ceramic, or a ceramic that protects the portable terminal 10 and reduces external impacts. Of these, it can be manufactured using any one material.

  The first cover 120 is formed in a plate shape and protects the portable terminal 10 while supporting the portable terminal 10. In addition, the second cover 140 is also formed in a plate shape, and is formed symmetrically with the first cover 120 around the portable terminal 10.

  The connection part 160 is formed between one side surface of the first cover 120 and one side surface of the second cover 140, and is interconnected so that the first cover 120 and the second cover 140 can be opened and closed. To do.

  The connection part 160 has flexibility and elasticity, and when the first cover 120 or the second cover 140 is opened upward, the first cover is formed by the flexibility and elasticity of the connection part 160. 120 and the second cover 140 are folded together after a predetermined time.

  The second cover 140 has one side surface coupled to the connection unit 160 and is formed symmetrically with the first cover 120 with the portable terminal 10 interposed therebetween. The second cover 140 and the portable terminal A fixing portion for fixing the portable terminal 10 is formed between the portable terminal 10 and the portable terminal 10 and the second cover 140 to increase an adhesive force.

  The second cover 140 includes a support base 141 whose one side surface is coupled to the connecting part 160, a pedestal 142 whose one side surface is rotatably coupled to the other side surface of the support base 141, and the support base 141 A bent portion 143 formed between the cradle 142 is included.

  One side of the support base 141 is coupled to the connecting part 160, and the other side forms a curved surface protruding toward the receiving base 142. One side surface of the cradle 142 is formed in a concave shape and is rotatably coupled to the other side surface of the support table 141.

  The bent portion 143 is formed across the second cover 140 so as to be parallel to the connecting portion 160 between the support base 141 and the pedestal 142, and the surface of the second cover 140 is An arcuate curved surface that bulges toward the cradle 142 is formed.

  The bent portion 143 is formed in a concave shape that is recessed between the support base 141 and the receiving base 142 in a cross-sectional view.

  When the cradle 142 is opened (as shown in FIG. 3, the pedestal 142 is rotated upward to stand), a structure capable of supporting the back surface of the portable terminal 10 is formed. It is like that.

  Here, the support base 141 and the receiving base 142 may be formed on the first cover 120 that is not the second cover 140.

  As shown in FIG. 2, the case 100 of the portable terminal further includes a fixing part 180 formed between the first cover 120 and the cradle 142.

  The fixing part 180 includes a fixing shaft 181 and an adhesive surface 182.

  In addition, the fixing unit 180 may be made of any one of a light, elastic metal, polymer, and ceramic to protect the portable terminal 10 and reduce external impact. Can be produced.

  The fixing part 180 is formed in a rectangular shape, and a part of the fixing part 180 protrudes along a side of the case 100 of the portable terminal along the cradle 142. The fixed shaft 181 is formed by connecting rivets, and is formed through the fixed portion 180 and the cradle 142.

  The fixing unit 180 is disposed between the second cover 140 and the portable terminal 10, and an adhesive surface 182 formed on the fixing unit 180 is bonded to the portable terminal 10 to be portable. The terminal 10 is not separated from the case 100 of the portable terminal.

  An adhesive material is formed on the adhesive surface 182 to increase the adhesive force between the portable terminal 10 and the fixing unit 180. Accordingly, even if the case 100 of the portable terminal is lifted, it is not separated from the portable terminal 10 bonded to the bonding surface 182.

  In addition, since a separate member for fixing the portable terminal 10 to the inside of the case 100 of the portable terminal is not required, the weight and volume of the case 100 of the portable terminal can be reduced. .

  The fixing unit 180 can be rotated through the fixed shaft 181, and the fixing unit 180 can be rotated to change the position where the portable terminal 10 is installed according to usage.

  As shown in FIG. 3, the bent portion 143 includes a first bent portion 143 a formed at one end of the bent portion 143 and a second bent portion formed at the other end of the bent portion 143. 143b.

  When the cradle 142 is rotated and opened (stands up) about the bent portion 143, a part of the first cover 120 is exposed to the outside, and the cradle 142 rotates while the cradle 142 rotates. Each of the first bent portion 143 a and the second bent portion 143 b moves toward the center of the second cover 140.

  The first bent portion 143a and the second bent portion 143b move toward each other (that is, move toward the inside), and accordingly, the other side surface of the support base 141 protrudes upward in a convex shape. It will bend.

  In addition, the center of the pedestal 142 protrudes toward the portable terminal 10 and bends due to the movement of the first bent part 143a and the second bent part 143b (see FIG. 5).

  Accordingly, the greater the angle at which the cradle 142 is opened and rotated, the greater the degree of bending of the support pedestal 141, and the increased elastic force of the support pedestal 141 increases the movement of the cradle 142 to open and rotate. I will resist.

  That is, when the cradle 142 rotates and opens, it has a restoring force that rotates in the opposite direction and tries to come into close contact with the first cover 120.

  The lower end of the fixing part 180 presses the first cover 120 when the cradle 142 is opened, and a space is formed between the cradle 142 and the first cover 120.

  Meanwhile, since the center of the cradle 142 is bent so as to protrude toward the portable terminal 10, the contact area between the cradle 142 and the portable terminal 10 is reduced. Stable deferment becomes difficult.

  Accordingly, the fixing unit 180 is disposed between the cradle 142 and the portable terminal 10 so that the portable terminal 10 can be stably placed on the cradle 142.

  As shown in FIG. 4, when the cradle 142 is opened and the other end of the fixing part 180 is pressed against the first cover 120, the cradle 142 moves upward, and the portable terminal 10 In a state of being in close contact with the fixing portion 180, it is deferred according to the intended use.

  Since the area where the fixing part 180 contacts the portable terminal 10 increases, the portable terminal 10 can be more stably placed on the cradle 142, and the surface of the first cover 120 The angle at which the portable terminal 10 is installed on the cradle 142 may be adjusted by changing the position of the fixing unit 180 that contacts the top.

  Further, it is possible to stably stabilize the cradle 142 by preventing the cradle 142 from rotating and restoring to the original position due to the frictional force caused by the contact between the fixed part 180 and the first cover 120. There is.

  Also, if the area where the fixing unit 180 contacts the portable terminal 10 increases and the area where the fixing unit 180 contacts the bonding surface 182 increases, the receiving table 142 and the fixing unit 180 may be moved by the elastic force of the receiving table 142. The portable terminal 10 is pressed and prevented from rising up.

  In addition, a plate-like member made of polymer, metal, or ceramic is disposed inside the support table 141 and the support table 142, and when the support table 142 opens more than a predetermined angle, A member of the base 141 is in contact with a member of the cradle 142 to prevent the cradle 142 from opening too much, and the portable terminal 10 can be stably placed.

  As shown in FIG. 5, the fixed part 180 is formed between the portable terminal 10 and the cradle 142, and the fixed part 180 and the cradle 142 are formed of the fixed shaft formed by rivets. 181 through 181.

  One end of the fixed shaft 181 is formed inside the fixed shaft 181 so that the fixed shaft 181 protrudes toward the portable terminal 10 and does not come into contact with the portable terminal 10. To do.

  The other end of the fixed shaft 181 is formed so as to pass through the cradle 142 and protrude toward the outside of the cradle 142, or to be disposed inside the cradle 142.

  When the cradle 142 is opened, both side surfaces of the cradle 142 move toward the fixed shaft 181, and the center of the cradle 142 protrudes toward the portable terminal 10 and bends.

  One side surface of the fixing unit 180 has a small area in contact with the pedestal 142, but is fixed by the fixing shaft 181 so as to be parallel to the coupling unit 160, and the other side surface of the fixing unit 180 is the mobile phone. The area in contact with the mobile terminal 10 is widely formed.

  Accordingly, the portable terminal 10 has a mechanically efficient arch-like structure that is generated when the pedestal 142 is bent and the pedestal 142 bends stably through the fixing unit 180. There is an advantage that the supporting force that is formed and supports the load of the portable terminal 10 is increased.

  In addition, since the structure of the cradle 142 deformed in an arch shape and the restoring force of the cradle 142 due to the bending of the support base 141 act simultaneously, a separate member for supporting the weight of the portable terminal 10 There is an advantage that no mounting is required.

  In addition, the fixing unit 180 may increase the adhesive force with the portable terminal 10 by arranging a magnet therein. Accordingly, the fixing unit 180 and the portable terminal 10 are in close contact with each other by magnetism, and the portable terminal 10 can be prevented from separating from the fixing unit 180 and slipping.

  In addition, if the portable terminal 10 is moved toward the cradle 142, the restoring force of the cradle 142 is gradually increased by the elastic force of the support base 141, and the portable terminal 10 Since the pressure applied to the fixing unit 180 increases due to the weight, the pressure of the weight of the portable terminal 10 and the restoring force of the cradle 142 are contradictory even at various angles, and the portable terminal 10 is stable. There is an advantage that a stationary member is possible, and a separate fixing member for fixing the fixing part 180 and the first cover 120 in a stepwise manner is unnecessary.

  In addition, when the restoring force of the cradle 142 is higher than the weight of the portable terminal 10, if the other end of the fixing unit 180 that contacts the first cover 120 comes into contact with the first cover 180, a frictional force is generated. By fixing the fixing members to be increased, the stationary of the cradle 142 and the portable terminal 10 can be stably maintained.

  Since the case of the portable terminal according to the present embodiment is substantially the same as the case 100 of the portable terminal of FIGS. 1 and 2 except for the third cover 190, the same reference numerals and names are used. In addition, overlapping explanation is omitted.

  As shown in FIG. 6, the case of the portable terminal includes a third cover 190.

  The third cover 190 includes a first locking part 191 and a second locking part 192.

  The third cover is coupled to the cradle 142 and is extended along the surface of the cradle 142. The cradle 142 is coupled to one side of the portable terminal 10 in a state where the portable terminal 10 is disposed between the first cover 120 and the second cover 140. The terminal 10 is fixed so as not to be separated from the cradle 142.

  When the cradle 142 rotates upward about the bent part 143 and opens, the display unit of the portable terminal 10 is exposed, and the portable terminal 10 is naturally placed on the cradle 142. .

  In this case, the portable terminal 10 is fixed by the third cover 190, and when the portable terminal 10 is larger than the area of the cradle 142, the first cover 120 is pressed against the first cover 120. The cradle 142 is moved upward.

  The first locking part 191 is formed in a hook shape and is coupled to one side surface of the portable terminal 10, and the second locking part 192 is formed in the same shape as the first locking part 191. And coupled to the other side of the portable terminal 10.

  The size of the first locking part 191 and the second locking part 192 is the first size when the cradle 142 is folded toward the first cover 120 while being coupled to the portable terminal 10. The locking part 191 and the second locking part 192 are formed lower than the thickness of the portable terminal 10 so as not to contact the first cover 120.

  Here, the third cover 190 is detachable from the cradle 142 so that the third cover 190 can be replaced with a third cover having a different size depending on the type of the portable terminal 10 used by the user.

  Since the case of the portable terminal according to the present embodiment is substantially the same as the case 100 of the portable terminal of FIGS. 1 and 2 except for the form of the bent portion 145, the same drawing number and name are used. The description which overlaps is abbreviate | omitted.

  As shown in FIG. 7, the bent portion 145 is different from the bent portion 143 of FIG. 1 in that the bent portion 145 is formed across the support base 141 and the receiving base 142. Is formed to protrude toward the connecting portion 160.

  When the cradle 142 is opened around the bent portion 145, the cradle 142 rotates at a predetermined angle, and when the cradle 142 rotates, the support pedestal 141 bends to rotate the cradle 142 in the opposite direction again. And has an elastic force to restore.

  When the cradle 142 is opened and rotated at a predetermined angle, the cradle 142 and the support base 141 come into contact with each other at the bent portion 145 to prevent the cradle 142 from rotating. 10 has resistance to be deferred.
