Each of these components will be described in detail below.

The mount plate 320 is fixed to the cover 200 and has guide holes 321A and 321B for guiding the extension bar 330 and guiding the base plate 310. The guide holes 321A and 321B are formed in an “L” shape in which the vertical guide holes 321A formed in the vertical direction and the left and right guide holes 321B formed in the left and right directions cross each other. In addition, the mount plate 320 includes auxiliary guide holes 322A and 322B formed in parallel with the vertical guide holes 321A and the horizontal guide holes 321B. Like the guide holes 321A and 321B, the auxiliary guide holes 322A and 322B are formed in an “L” shape in which the upper and lower auxiliary guide holes 322A and the left and right auxiliary guide holes 322B cross each other. . The auxiliary guide holes 322A and 322B serve to guide the base plate 310.

The base plate 310 is fixed to the main body 100 and coupled to the mount plate 320 so as to be movable in the vertical direction and the left and right directions. To this end, the base plate 310 is first coupled by the first slide pin 311 penetrating the guide holes 321A and 321B to move along the guide holes 321A and 321B of the mount plate 320. do. Secondly, the second slide pin 313 penetrates the auxiliary guide holes 322A and 322B to move along the auxiliary guide holes 322A and 322B of the mount plate 320. As a result, the base plate 310 is capable of stable sliding in the vertical direction and the left and right directions based on the mount plate 320. Here, the base plate 310 is provided with a fastening hole 314 for fastening the second slide pin 313.

The elastic bar 330 is hinged to the mount plate 320 and the base plate 310, respectively, and connects the two, and can stretch and contract by the elastic force of the tension spring 338, which is elastic. . To this end, the elastic bar 330 is composed of a combination of the first elastic bar 330A, the second elastic bar 330B, the tension spring 338 which is an elastic means.

Here, the first elastic bar 330A is hinged to the mount plate 320 by a coupling pin 336. As a result, the first elastic bar 330A can rotate clockwise and counterclockwise with the coupling pin 336 as the central axis. In this case, the first elastic bar 330A may be hinged to the middle portion of the body by the coupling pin 336. This is to optimize the space placement efficiency by reducing the rotation radius of the first expansion bar (330A). For reference, reference numeral 323 which is not described above is a coupling pin coupling groove for screwing the coupling pin 336.

The second elastic bar 330B is coupled to the first elastic bar 330A in a direction opposite to the first elastic bar 330A so as to be moved forward and backward. To this end, the second elastic bar 330B is provided with a cutout 331 formed along the longitudinal direction and the coupling pin 336 is penetrated. Since the second elastic bar 330B is provided with the cutout 331, the second elastic bar 330B can be moved forward and backward with respect to the first elastic bar 330A even when the second elastic bar 330B is coupled to the first elastic bar 330A by the coupling pin 336. As described above, the coupling pin 336 serves to couple the first elastic bar 330A to the mount plate 320 and to elastically couple the first elastic bar 330A and the second elastic bar 330B. It can be seen that. Meanwhile, the front end portion of the second elastic bar 330B is connected to the base plate 310 through the guide holes 321A and 321B. To this end, the base plate 310 and the front end portion of the second elastic bar 330B are simultaneously fastened with the first slide pin 311 penetrating the guide holes 321A and 321B. Pin fastening holes 312 and 339 are formed at the distal ends of the base plate 310 and the second elastic bar 330B to fasten the first slide pin 311. As a result, the base plate 310 and the second elastic bar 330B may be coupled with the mount plate 320 interposed therebetween to move along the guide holes 321A and 321B.

The tension spring 338, which is the elastic means, is positioned in the overlapping section of the first elastic bar 330A and the second elastic bar 330B, and a rear end of the first elastic bar 330A and the second elastic bar. It serves to pull the rear end of the (330B). To this end, the first elastic bar 330A and the second elastic bar 330B are formed to protrude from the rear end to the left and right, respectively, and include spring hook parts 333 and 337 to hang the ends of the tension spring. . The spring hook portions 333 and 337 are provided with spring hook holes 333A and 337A to hook both ends of the tension spring 338, respectively.

Hereinafter, the operation of the hinge module 300 according to the present invention will be described with reference to other drawings attached with reference to FIGS. 8 to 12. 8 to 12 are reference views for explaining the operation of the hinge module according to the present invention.

First, FIG. 8 shows a state of the hinge module 300 in a state in which the main body 100 is closed with respect to the cover 200 of the mobile terminal according to the present invention. In this state, the base plate 310 is biased to the upper side and the left side with respect to the mount plate 320.

At this time, the first slide pin 311 located in the base plate connecting portion 315 is located at the intersection point 321C of the up-down direction guide hole 321A and the left-right direction guide hole 321B, and the elastic bar 330 is relatively relaxed. Is in. At this time, the elastic bar 330 is not completely relaxed, but still has a tendency to stretch by the tension spring 338. Therefore, the base plate connection portion 315 tends to stay at the intersection 321C, thereby maintaining the main body 100 closed with respect to the cover 200 unless an external force is applied.

Afterwards, when the main body 100 moves downward due to an external force, the base plate 310 fixed to the main body 100 also moves downward. Then, as the base plate connecting portion 315 moves along the vertical guide hole 321A, the elastic bar 330 rotates the coupling pin 336 in the counterclockwise direction. At this time, the elastic bar 330 is gradually reduced in length as opposed to the tendency to stretch. Thereafter, as shown in FIG. 9, the length of the base plate connecting portion 315 is about the middle of the vertical guide hole 321A and becomes the minimum to reach the transition point. At this time, the elastic energy accumulation value of the tension spring 338 reaches a maximum value.

Subsequently, after the external force is continuously applied to the main body 100 in a downward direction, the base plate is instantaneously changed from the upward direction to the downward direction when the action direction of the elastic bar 330 having a tendency to stretch is passed. It coincides with the moving direction of 310. As a result, as shown in FIG. 10, the base plate connection part 315 moves rapidly downward and is positioned at a lower end of the upper and lower guide holes 321A, and the base plate 310 is also moved downward to be located in the main body. 100 is in a state opened downward. If the external force applied to the main body 100 disappears before reaching the transition point, the main body 100 is moved upward and closed by the elastic bar 330 having a tendency to stretch.

As such, when the main body 100 moves downward to open, the elastic bar 330 is in a relatively relaxed state. However, the elastic bar 330 is not completely relaxed, but still has a tendency to stretch by the tension spring 338. Therefore, the base plate connecting portion 315 tends to stay at the lower ends of the guide holes 321A and 321B, whereby the main body 100 moves downward with respect to the cover 200 unless an external force is applied. Will remain open.

On the other hand, as shown in FIG. 8 when the main body 100 is moved to the right direction by applying an external force to the cover 200, the main body 100 is closed, the base plate 310 fixed to the main body 100 ) Will also move in the right direction. Then, the base plate connecting portion 315 is moved along the left and right guide hole 321B and the elastic bar 330 rotates the coupling pin 336 clockwise about the axis. At this time, the stretch bar 330 is gradually reduced in length as opposed to the tendency to stretch. Thereafter, as shown in FIG. 11, the base plate connecting portion 315 is positioned at the middle of the vertical guide hole 321A, and the length thereof is minimized to reach a transition point. At this time, the elastic energy accumulation value of the tension spring 338 reaches a maximum value.

Subsequently, after the external force is continuously applied to the main body 100 in the right direction, the base plate 310 is instantaneously changed from the left side to the right side while the action direction of the elastic bar 330 having a tendency to stretch is passed. ) Will coincide with the direction of travel. As a result, as shown in FIG. 12, the base plate connection part 315 moves rapidly in the right direction and is immediately positioned at the right end of the left and right guide holes 321B. As the base plate 310 is also located on the right side, the main body 100 is opened in the right direction. If the external force applied to the main body 100 disappears before reaching the transition point, the main body 100 moves to the left and closes to its original state by the elastic bar 330 having a tendency to stretch.

As such, when the main body 100 is moved to the right and opened, the elastic bar 330 is in a relatively relaxed state. However, the elastic bar 330 is not completely relaxed, but still has a tendency to stretch by the tension spring 338. Therefore, the base plate connecting portion 315 tends to stay at the right end of the guide holes 321A and 321B, whereby the main body 100 is in the right direction with respect to the cover 200 unless an external force is applied. Will remain open.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.
