The 'b' shaped bent portion 19 of the fixed plate 18 is coupled to the guide groove 13 of the guide portion 21 of the sliding body 20, the guide rod 16 is coupled to the moving hole 22 The status is shown.

A micro gap is set between the guide groove 13 and the 'b' type bent portion 19 to smoothly guide the assembly tolerance and sliding. In the initial use of the mobile phone, this gap does not affect the sliding movement of the folder portion, but if the use continues, deformation occurs in the guide groove 13 or the 'b'-type bent portion 19, thereby expanding the gap, whereby the folder portion ( As the coupling between 2) and the main part 1 becomes loose, play is generated between the folder part 2 and the main part 1. This reduces the operation peeling of the folder part 2 and becomes a factor which worsens mobility. However, according to the present invention, the sliding body 20 and the folder portion 2 coupled thereto by the coupling of the moving hole 22 and the guide rod 16 are fixed to the body 10 and the main portion 1 coupled thereto. Since the lateral flow is supported so as to be prevented against the coupling of the 'b' type bent portion 19 and the guide groove 13 while maintaining a constant mobility of the sliding body 20 with respect to the fixed body 10 maintain.

In addition, the present invention is the guide channel coupled to the guide groove 23 is bent 'b' shape to improve the strength and at the same time improve the workability. In the slider-type mobile phone, a 'c' type guide channel may be formed to surround the side end of the sliding body 20.

However, according to the present invention, the guide channel is formed through one press work by forming the side end of the metal plate as a 'b'-shaped bent part to slide along the guide groove 23 of the guide part 21 of the sliding body 20. It is possible to do

7 is a block diagram of a hinge assembly according to the present invention. Referring to the drawings, the hinge assembly 30 according to the present invention has a hinge body 33 having three channels 31 of cylindrical grooves therein. Hinge body 33 is the upper body (33-2) and lower body (33-1) are each manufactured by injection molding is assembled by the fitting method. This method not only facilitates the formation of the channel 31, but also minimizes the thickness of the hinge body 33 to enable slimming of the mobile phone. A step 33-2 is formed at the open side of the channel 31. On the end side of the hinge body 33, the first hinge protrusion 33-4 is formed downward (refer to the direction of FIG. 7). The first hinge protrusion 33-4 is rotatably coupled to the fixed plate 18 and the first hinge portion 17.

The hinge body 33 is installed to be movable while the moving body 35 is supported by the spring 36. The moving body 35 is formed of a support part 32 having a second hinge protrusion 32-1 and three cylinder bars 34 extending from the support part 32 in a rod form. A locking jaw 36 is formed at the end side of the cylinder rod 34, and a spring support rod 37-1 supporting the spring 36 is formed.

Accordingly, the spring 36 is fitted in the end direction of the cylinder rod 34 to be installed in the channel 31 of the hinge body 33, and the upper body 33-2 is coupled to the lower body 33-1. At this time, the locking step 37 of the cylinder rod 34 is caught by the step 33-3 of the channel 31 to prevent the separation. As a result, the spring 36 is compressed while the moving body 35 moves in a direction close to the hinge body 33, and at this time, the folder part 2 is automatically lifted with respect to the main part 1 by the stored force. It is possible to do Of course, the opposite operation works on the same principle.

According to the hinge assembly 30 according to the present invention, because the hinge body 33 is composed of the assembly of the upper body 33-2 and the lower body 33-1, which are injection moldings on which the channel 31 is formed, By minimizing the thickness of the hinge assembly 30 installed between the body 10 and the sliding body 20, it is possible to slim the mobile phone. The hinge body 33 is provided with a channel 31 in which the spring 36 is installed. In the case of forming the hinge body 33 through injection molding, the hinge body 33 forms a plurality of channels 31 integrally. Not only is it possible, but it is also possible to minimize the thickness of the hinge body 33 with the channel 31. That is, when the thickness of the portion where the channel 31 is formed in the hinge body 33 is set to the minimum thickness required for strength, the thickness of the hinge body 33 is adjusted to the minimum thickness that satisfies the strength condition. In contrast to the case of using a rod-type channel, in addition to the thickness of the rod-type channel, a thickness of a fixing part for fixing a plurality of separate channels into one is added to determine the thickness of the hinge assembly. This is a factor of increasing the thickness of the slide assembly by increasing the thickness of the hinge assembly.

On the other hand, the hinge assembly 30 according to the present invention is characterized in that the moving body 35 which is close to and spaced from the hinge body 33 is formed to one side. Since the movable body 35 is formed on one side, assembling property is improved in comparison with a structure in which the movable body is formed on both sides with the hinge body 33 at the center, and the action mechanism of the force centered on the hinge is simplified. Thus, forces acting in opposite directions to each other are formed in the hinge parts, thereby preventing the problem of hindering the operation of the hinge assembly.

Referring to Figures 3, 8a and 8b looks at the operation of the hinge assembly according to the present invention. When the sliding body 20 moves to the left side (see FIG. 3) with respect to the fixed body 10 in the state shown in FIG. 3, the movable body 35 of the hinge assembly 30 is hinged as shown in FIG. 8A. While moving in the direction close to the body 33, the first hinge 17 and the second hinge portion 25 to the position closest to the maximum. At this time, the spring 33 is compressed while the cylinder rod 34 moves inward along the channel 31. However, the distance between the first hinge portion 17 and the second hinge portion 25 is gradually spaced apart after the hinge portion closest to the hinge portion shown in FIG. 8b, in which case the compressed spring 33 is restored by the elastic force and slides. The body 20 is automatically pushed up to the state of FIG. 8C.

That is, the force pushing up the folder by the user up to the hinge closest position is stored in the spring of the hinge assembly to automatically push up the folder through the hinge closest position. Of course, this operation is a result of the rotation of the hinge protrusion about the hinge portion and the movement of the movable body 35 relative to the hinge body 33. In this case, when the puller unit is moved upward with respect to the main unit in the slide type mobile phone to open the folder unit, the mobile phone user manipulates the folder unit to which the sliding body 20 is coupled to move the state to the state of FIG. 8B by hand. In this case, the folder part is automatically opened by moving from the state of FIG. 8B to the state of FIG. 8C. This improves the operation performance of the folder unit in the slider type mobile phone.

Hereinafter will be described the operation of the mobile phone folder opening and closing slide assembly according to the present invention.

When a call is received on the mobile phone, the user typically moves the folder part of the mobile phone upward by using a thumb while holding the mobile phone in one hand.

At this time, the sliding body 20 coupled to the folder portion is moved upward with respect to the fixed body 10 by a user pushing up the cellular phone folder portion, by which the hinge protrusion rotates on the hinge portion and hinges. The moving body 35 of the assembly 30 moves in a direction approaching the hinge body 33. Then, the spring 36 installed in the channel 31 of the hinge body 33 is compressed until the hinge body 33 is moved to the closest position by the movement of the sliding body 20.

However, after passing through the maximum position of the hinge portion, the compressed spring 36 is restored and a restoring force is generated, and by this force, the movable body 35 automatically moves in a direction away from the hinge body 33, At this time, the sliding body 20 is automatically moved to the state of Figure 8c by the restoring force of the spring 36 with respect to the fixed body (10). As a result, the folder part is automatically moved upwardly and vertically with respect to the main part to be opened in an open state.

That is, when the hinge assembly is rotated while the spring 36 is compressed by the initial upward movement of the folder portion, and the predetermined position is reached, the folder portion is restored by the restoring force of the spring 36 even if the user does not apply a pushing force to the folder portion any more. It will automatically move upward straight line.

Of course, the movement of the sliding body 20 is made inside the two fixing pieces 14, the movement amount of the sliding body 20 is controlled by the fixing piece (14).

If you want to close the mobile phone folder after the call is closed in the same principle.
