6 to 12 are views showing the operation of the rotary unit shown in Figs.

FIG. 13 is a side view illustrating the portable terminal of FIG. 1.

As shown in FIGS. 1 to 4, the portable terminal 20 includes a liquid crystal display unit 21, a key button unit 22, and a hinge device 10. The liquid crystal display unit 21 displays screen information through a display screen, and the key button unit 22 is used to input information using a plurality of keys. The hinge device 10 is a component that connects the liquid crystal display unit 21 and the key button unit 22 and rotates the liquid crystal display unit 21 with respect to the key button unit 22 and rotates at the same time. For this, the first slider 120, the second slider 110, the elastic body 130 and the rotation unit 140 are included.

In addition, the second slider 110 bends the width direction on both sides of the plate shape to form the guide piece 112, and the first slider 120 bends the width direction both sides in the shape of a "c" to guide grooves 122. To form.

The elastic body 130 has a form protruding in opposite directions to both ends of the coil wound, but is a means for forming an elastic force through the wound portion, generally, the first slider 120 and the second slider 110. Any type of elastic body is possible as long as the elastic force can be applied to the side.

As shown in FIG. 4, the rotating unit 140 includes a housing 141, a spring 142, a rotating cam 143, a moving cam 144, a fixed cam 145, a bracket 146, and a rotating shaft ( 147). The housing 141 has a plate body extending to one side and an empty inside thereof, and the plate body is connected to the first slider 120. Thus, the housing 141 rotates with the first slider 120.

The housing 141 has an inner space, and the spring 142, the rotating cam 143, the moving cam 144, and the fixed cam 145 are sequentially inserted into the inner space of the housing 141. One end of the spring 142 is in contact with the interior of the housing 141, the other end of the spring 142 is in contact with the rotary cam 143, the fixed cam 145 relative to the rotary cam 143 and the mobile cam 144. It provides an elastic force in the facing direction. The rotating shaft 147 penetrates the housing 141, and the spring 142, the rotating cam 143, the moving cam 144, and the fixed cam 145 are sequentially installed on the rotating shaft 147. One end of the rotating shaft 147 is connected to the bracket 146, the bracket 146 is fixed to the key button portion 22.

The rotating shaft 147 has a stationary body 147a, and the stationary body 147a generally has a stationary surface 147b. The fixed cam 145 has a limiting surface 145b in contact with the fixed surface 147b, and the fixed surface 147b restricts the movement of the limiting surface 145b to limit the rotation of the fixed cam 145.

The fixed cam 145 has a fixed cam protrusion 145a opposed to the moving cam 144, and the fixed cam 145 moves relatively along the moving surface 144a.

The moving cam 144 has a moving surface 144a facing the fixed cam 145 and a guide surface 144b facing the rotating cam 143. The fixed cam protrusion 145a moves relatively along the moving surface 144b by the rotation of the moving cam 144.

The rotary cam 143 has a locking jaw 143a protruding to the outer circumferential surface, and the locking jaw 143a contacts the cutout surface 141a formed in the housing 141 to limit the rotation of the rotating cam 143. Thus, the rotary cam 143 rotates together with the housing 141. In addition, the rotary cam 143 has a rotary cam protrusion 143b and a rotary cam surface 143c moving along the guide surface 144b of the mobile cam 144.

Hereinafter, the operating state of the present invention will be described with reference to FIGS. 6 to 12.

As shown in FIG. 6, when the LCD screen 21 is pressed in the direction of the arrow on the drawing in the state where the LCD screen 21 and the key button unit 22 are overlapped (or 'limited position'), 2, the slider 110 is guided along the first slider 120 and slides, thereby sliding the LCD screen. At this time, the elastic body 130, which holds and connects the first slider 120 and the second slider 110 with each other, is compressed and has a compressive force. When the compressed elastic body 130 is in a position where the compressive force is at its peak (that is, the liquid crystal display part is slid open to a part of the key button part in an open state), the compressed elastic body releases the compressive force and the liquid crystal display part has one side of the key button part. To make it move automatically (or switch to the 'release position'). In this case, the bracket 146 is fixed to the key button part 22 side, and the housing 141 is connected to the first slider 120.

Meanwhile, as shown in FIG. 13, in the state where the liquid crystal display unit 21 and the key button unit 22 overlap, the rotation of the first slider 120 is performed by the liquid crystal display unit 21 and the key button unit 22. It is limited by ('restricted position'), it is possible to rotate the first slider 120 when the second slider 110 is moved along the first slider 120 (switched to the 'release position').

As shown in FIG. 7, the fixed cam protrusion 145a of the fixed cam 145 in the housing 141 is positioned on the inclined surface B of the moving surface 144a of the moving cam 144, and moves. The cam 144 and the rotary cam 143 are connected to the cam protrusion 144a and the rotary cam surface 143c while the LCD screen 21 is slid and the second slider 110 is switched to the 'release position'. The housing 141 rotates. At this time, the fixed cam projection 145a of the fixed cam 145 is guided and moved along the moving surface 144a of the mobile cam 144 in the housing, and the housing 141 rotates through the moving cam 144a. That is, the fixed cam projection 145a in the state located on the inclined surface B side is seated on the seating surface C and then moved toward the stop surface A, and the LCD screen portion slid with respect to the key button part 22. 21 rotates to have a predetermined angle with respect to the key button portion 22.

For example, the housing rotates while the cam protrusion 145a located in the cam groove 144b operates in the cam groove 144b, and the liquid crystal display unit 21 can rotate by rotating the housing. In addition, since the second cam portion 144 is engaged with the third cam portion, the housing can be rotated, and the view of the screen can be easily secured through the liquid crystal display portion which is inclined to the key button portion. Will be.

Next, in order to adjust the inclination angle of the liquid crystal display unit 21 while the liquid crystal display unit 21 maintains the inclination angle with respect to the key button unit 22, the fixed cam protrusion 145a is provided. Pulling the liquid crystal display unit 21 in a state of being bound to the cam groove 144a of the mobile cam 144, the mobile cam 144 rotates from the mobile cam 144 in a state in which movement is restricted by the fixed cam unit 145. Only the cam 143 is separated and the housing 141 is rotated through the rotation of the rotary cam 143 to allow the liquid crystal display unit 22 to rotate.

For example, as described above, the slidable liquid crystal display unit is in a state of being tilted at an angle (10 to 15 °) by an operation of the fixed cam and the mobile cam. In this state, the inclination angle of the liquid crystal display unit in the inclined state can be further inclined through the operation of the mobile cam and the rotating cam, so that the visible field of view of the liquid crystal display unit can be variously adjusted. In other words, the liquid crystal display unit in the minimum sliding state has an inclination angle at the same time as the key button unit and the horizontal state or the sliding opening, making it easy to secure the screen field of view, and the user can adjust the inclination angle more variously than the inclined state. It can be adjusted at various angles according to the line of sight, making it easier to secure the view of the screen.

On the other hand, for example, the moving cam 144 is formed with the inclined surface and the stop surface (A, B) in the direction in which the moving surface 144a is formed by the rotation axis 147, the inclined surface (A) is the seating surface (C) Acute angle with respect to), stop surface (B) is an obtuse angle with respect to the seating surface (C). Therefore, the fixed cam protrusion 145a moves along the inclined surface A, and the movement is limited by the stop surface B. FIG.

The present invention is not limited by the embodiments described above, and various changes and modifications can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

The present invention can be applied to various products (especially portable terminals) using the hinge device.
