It comprises a button unit 26 capable of pressing.

The hinge long body 17 is formed long in the shape of a pipe along the longitudinal direction of the lower end of the cover portion 15, both sides are in contact with the hinge points (16a, 16b) provided on the upper end of the main body (13). Here, the hinge points 16a and 16b are formed at the right side and the left side of the figure, respectively. The hinge point 16b of the left side part is provided with the hinge 18 engaged with the left side part of the hinge-length body 17. As shown in FIG. One side of the hollow shaft 19, which will be described later, is coupled to the hinge point 16a on the right side, and the shape is hemispherical corresponding to the shape of the engaging portion of the hollow shaft 19. As shown in FIG. That is, the long hole of the hinge body 17 is provided to form a straight line with the hinge points (16a, 16b) of the left and right portions.

The hollow 19c has a diameter into which the button bar 24 to be described later is inserted, and the stem portion 19b is provided in a circular bar shape, and the locking jaw 19d is caught by the inner wall of the rotating body 22 to be described later. ) Is formed, and the shape of the part fixed to the hinge point 16a has a hemispherical shape corresponding to the shape of the hinge point 16a. In addition, the stem portion 19b has a groove 19e formed at a portion where extension starts from the head portion 19a, and the groove 19e has one end of the coil spring 21 that can be elastically twisted or restored. This insert is fixed. In addition, the head part 19a is provided with the 1st protruding piece 19f extended in the axial direction, ie, toward the hinge point 16b of the left part of the main body 13. As shown in FIG. The first protrusion 19f protrudes to have a width equal to the outer circumference of the head portion 19a and the inner wall thickness of the hollow 19c.

The rotating body 22 is provided in a cylindrical tubular shape so that the hollow shaft 19 is insertable, and the locking jaw 19d formed at the stem portion 19b of the hollow shaft 19 is inserted when the hollow shaft 19 is inserted. It is formed stepwise so as to have outer periphery of different diameter so as to be caught. In addition, a locking hole 22a is formed in the body of the rotating body 22 to catch the other end of the coil spring 21 described above, and the pin member is coupled through the pin hole 17b of the hinge body 17. An insertion hole 22b is formed so that the 23 can be inserted. That is, the rotor 22 is rotated together around the hollow shaft 19 as the cover portion 15 is covered to provide a torsional force to the coil spring (21). In other words, since the other end of the coil spring 21 is hung, the rotating body 22 twists the coil spring 21 when the cover 15 is rotated, thereby achieving a tensioned state. On the contrary, when the torsional force of the coil spring 21 is released, the rotating body 22 rotates about the hollow shaft 19 by the restoring force of the coil spring 21. In addition, the outer peripheral end of one side of the rotating body 22, that is, the head portion 19a of the hollow shaft 19 is extended in the longitudinal direction from the end of the outer circumference to be detachable with the clip member 25 to be described later. 22 C of protrusions which protrude and oppose each other are formed.

It has a predetermined elastic force and is opened when an external force is applied, and returns to its original position when the external force is removed. And the said clip member 25 is made to be removable by the 2nd protrusion piece 22C of the rotating body 22 to the space which opened. That is, as the button bar 24 is moved back and forth by the elastic force of the elastic spring 27 is easily removable.

One end of the button bar 24 protruding to the outside of the main body 13 is coupled to the button portion 26, and is coupled to and supported by the main body 13 to an elastic spring 27 coupled to the button bar 24. Press operation is possible.

Hereinafter, the operation and operation of the folding-type mobile phone having a cover opening device according to an embodiment of the present invention will be described in detail.

First, as shown in FIGS. 3A and 3B, the lid opening device of the present invention is in an initial state, and when the lid part 15 is open, the clip member 25 is the second protrusion piece of the rotating body 22 ( 22C), and one side of the hollow shaft 19 is fixed to the hinge point 16a of the right portion. Further, the first projection piece 19f of the hollow shaft 19 stands in the lateral direction in the clip member 25. In other words, the first projection piece 19f is positioned between the second projection piece 22C and is positioned substantially in line with the second projection piece 22C. At this time, the coil spring 21 fixed to both ends of the hollow shaft 19 and the rotating body 22 forms an initial state in which no external force is applied.

Next, in the case of closing the open lid 15, as shown in Figs. 4a and 4b, the lid 15 is in the direction A shown by the arrow in the figure around the hinge points (16a, 16b) on the left and right sides. Is rotated accordingly.

In more detail, as described above, when the cover part 15 is rotated, the rotating body 22 has a rotational direction of the cover part 15 around the hollow shaft 19 fixed to the main body 13. Rotate in the same B direction. At this time, the clip member 25 is rotated together while being coupled to the second protrusion piece 22C of the rotating body 22, and the body of the first protrusion piece 19f is connected to both contact points on the inner surface of the clip member 25. Contact and interfere. That is, the first protruding piece 19f has both contact points of the clip member 25 from the inside to the outside as the cover member 15 is continuously rotated and the clip member 25 is rotated together with the rotating body 22 at the same time. Pressurize slowly. In addition, the coil spring 21 is twisted as the rotating body 22 is rotated to some extent, and thus restoring force acts in the C direction. If the external force is removed before the cover part 15 reaches 90 °, the cover part 15 is rotated to its original position along the C direction by the restoring force and then unfolded again.

On the other hand, when the cover part 15 reaches the 90 degree position, the said 1st protruding piece 19f presses both contact points on the inner surface of the clip member 25, and opens it to the maximum by the width of the protruding piece 19f. That is, unlike the initial state in which the first projection piece 19f and the second projection piece 22C are located in a straight line, they are substantially triangular. Therefore, the first projection piece 19f is maximally opened by interfering the clip member 25 by a distance that forms a triangle with the second projection piece 22C. When the cover part 15 is out of 90 °, the first protruding piece 19f is also out of both contact points of the clip member 25, and the pressing force of the first protruding piece 19f is released from the both contact points. Is removed. Therefore, the clip member 25 is instantaneously restored again by the inherent elastic force, and the elastic force interferes with the first protruding piece 19f to further rotate the rotating body 22 in the B direction. Therefore, the cover part 15 is arbitrarily rotated by the restoring force of the clip member 25 to cover the front surface of the main body 13 even when the clip member 25 is restored to its original position without the user applying external force. Here, the first projection piece 19f and the second projection piece 22C form a straight line in the original position, but the first projection piece 19f is in strong contact with both contact points of the clip member 25 to maintain ultra-tension. do. At this time, the coil spring 21 is twisted and contracted as much as possible to form a tensioned state, whereby the coil spring 21 provides the maximum restoring force acting in the C direction on the rotating body 22. In addition, the rotational force of the rotating body 22 by the restoring force of the coil spring 21 is constrained by the clip member 25 coupled to the second protrusion 22C.

On the other hand, when trying to expose the front surface of the main body 13 by opening the closed cover part 15, as shown in Figs. 5A and 5B, the button portion 26 protruding to the outside of the main body 13 Press the cover portion 15 is automatically unfolded.

That is, the button portion 26 is pressed with one hand. Then, the button bar 24 is supported by the elastic spring 27 to move backward in the D direction shown in the drawing, and at the same time the clip member 25 is released from the second protruding piece 22C and is separated in the E direction. . Thus, the restraint of the rotational force of the rotating body 22 in which the restoring force of the coil spring 21 acts strongly is released. Therefore, as soon as the clip member 25 is separated from the second protrusion piece 22C, the rotor 22 rotates by approximately 180 ° in the F direction by the maximum restoring force acting in the C direction. Therefore, the cover part 15 is rotated together as the rotating body 22 is rotated and unfolded so that the front surface of the main body 13 is exposed. Therefore, the same state as in FIGS. 3A and 3B shown above is maintained. Finally, when the force applied to the button portion 26 is removed, the button bar 24 is elastically biased by the elastic spring 27 to return to the original position, and the button portion 26 also returns to the original position. come.

The present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various design variations are possible by those skilled in the art within the scope of the technical idea of the present invention. .

As described above, the clamshell mobile phone having a cover opening device according to a preferred embodiment of the present invention can easily open the cover of the mobile phone by pressing a button formed on the main body of the mobile phone, anytime under any circumstances the cover of the mobile phone The first advantage is that it can be unfolded quickly, making it particularly convenient to use while driving. In addition, the second advantage is that the structure is simple, the manufacturing cost is low, and productivity is improved.
