The present invention relates to an opening and closing device of a mobile communication terminal, and more particularly, to a bi-directional rotation and slide opening and closing device for a mobile communication terminal that can be simultaneously rotated and the display member of the mobile communication terminal.

In recent years, as the penetration rate of portable wireless terminals increases, additional functions that are suitable for the user's taste are required for the portable terminals, as well as simple functions of wireless communication.

In response to these demands, portable terminals have been developed from a general bar type to a flip type, a flip up type, a folder type, and the like. It is mainstream.

This is because a folder type terminal has enough space to adopt a wide LCD module as a display device, and because it is folded in half and portable, the portability is superior to other terminals.

On the other hand, it is possible to have a display device having a wide LCD module of a similar size as a folder type terminal, and at the same time, a slide type terminal capable of contributing to the miniaturization of the terminal is known.

Such a slide type terminal has an additional advantage that the sub body corresponding to the cover is opened and closed by a sliding operation on the main body, and is opened and closed by a new operation while maintaining the advantages of the existing folder type terminal.

As such a slide type terminal, a sliding type portable wireless terminal is disclosed in Utility Model Registration Application No. 2003-0000136.

The terminal disclosed in this application is adapted to change the direction of the pressing force in an opening direction or a closing direction with respect to a guide means for guiding the slide body on the main body and a sliding position of the slide body between the slide body and the main body. It includes at least one elastic means is installed. And the elastic body can maintain the maximum open position or the maximum closed position without a separate stopper during the fully open or closed operation. As such elastic means, a torsion spring is adopted in which one end is fixed to the main body and the other end is fixed to the slide body.

By the way, since the torsion spring applies an elastic force to the slide body while the torsion spring rotates, the torsion spring is greatly tensioned and unfolded. For this reason, the torsion spring is operated largely while using less elastic force, and two torsion springs are arranged to compensate for the insufficient elastic force.

Therefore, the conventional slide opening and closing device, the assembly process is complicated by using two torsional springs, there is a problem that its life is shortened as the displacement of the torsional spring increases.

In addition, the applicant of the present invention has applied for a display rotating device of a communication terminal through the patent application 2004-48684.

By rotating the display member so as to lengthen the liquid crystal screen in the horizontal direction, the rotating device can display a movie of a normal size or the like using the entire liquid crystal screen.

By the way, this application has described the comprehensive rotation operation without mentioning the limitation that the display member is rotated only in one specific direction. However, in the exemplary embodiment of the present application, there is shown a structure in which the display member can rotate only in one direction.

On the other hand, if the user is not habitually accustomed to the direction in which the display member is rotated, it is inconvenient to check the rotatable direction every time the display member is rotated. Therefore, if the display member is rotated in both directions, the user may feel convenient.

In addition, the user may feel more convenient if the display member is rotated in both directions and the slide opening and closing is possible at the same time.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide a bidirectional rotation and slide opening and closing device for a mobile communication terminal capable of rotating a display member of a mobile communication terminal in both directions and simultaneously opening and closing a slide.

A pressing member 400 for generating; And a braking member for limiting further rotation of the first slide member 200 in a state where the first slide member 200 is rotated by a predetermined angle with respect to the swing member 100.

This will be described in more detail with reference to FIGS. 3 and 4 as follows.

3 and 4, the swing member 100 is fixed to the display member (not shown) of the mobile communication terminal to rotate, the central axis 110 is formed in the center area. The central shaft 110 is formed with a central hole 112 through which a signal line connected to the main body and the display member passes. The slide block linear movement guide hole 120 facing outward from the edge region of the central axis 110 is formed radially. The slide block linear movement guide hole 120 is for guiding the horizontal movement by mounting the slide block 410 to be described later.

The first slide member 200 is rotatably coupled to the central axis 110, the cam 210 is formed on one side thereof. The cam 210 is radially formed from the rotation center, and the protrusions 212 protrude from the reference position at a predetermined angle. Each protrusion 212 is formed at 90 ° intervals. A central axis insertion hole 214 is formed in the central region of the cam 210 to accommodate the central axis 110.

The cover member 300 is coupled to the first slide member 200 in a state of covering the swing member 100 at the periphery thereof, and a central region of the cover member 300 is opened to allow a part of the swing member 100 to be coupled to the display member. do.

The pressing member 400 is for generating a predetermined stopping force by pressing the cam 210 in a state where the swing member 100 is not rotated and rotated at a predetermined angle, and the slide block of the swing member 100. The slide block 410 is installed in the linear movement guide hole 120 so as to be movable horizontally and is composed of a spring 420 for pressing the slide block 410.

The slide block 410 is installed in contact with the cam 210 in a state of being fitted into the slide block linear movement guide hole 120 of the swing member 100. Protrusions 412 are formed on both sides of the surface opposite to the cam 210, and springs 420 are fitted to the protrusions 412. The spring 420 elastically supports the slide block 410 to press the cam 210 at a predetermined pressure.

The braking member is for restricting the rotation of the swing member 100 coupled to the display member at a predetermined angle and further rotating. The braking member 114 and the cam 210 are formed on the central shaft 110. It is composed of a locking jaw 216 formed in the central axis insertion hole (214).

The locking protrusion 114 is formed to protrude in the longitudinal direction of the central axis 110 at the free end of the central axis 110.

The locking jaw 216 is formed at two locations of the central shaft insertion hole 214 to limit the rotation of the swinging member 100 by a predetermined angle when caught by the locking protrusion 114 in both directions. That is, the locking protrusion 114 is formed at the 12 o'clock direction of the central axis 110, and the locking jaw 216 is formed at the 3 o'clock and 9 o'clock positions of the central axis insertion hole 214. Therefore, when the swing member 100 is rotated in the counterclockwise direction, the locking projection located at the 12 o'clock position rotates counterclockwise to contact the locking jaw 216 located at the 3 o'clock position, and conversely, the swing member 100 is rotated. When rotated clockwise, the locking projection 114 located in the 12 o'clock direction rotates clockwise to contact the locking projection 216 located in the 9 o'clock direction.

5 is a perspective view of the mobile communication terminal shown in FIG. 1, FIG. 6 is a perspective view showing a state in which the display member of the mobile communication terminal shown in FIG. 1 is rotated, and FIG. 7 is a movement shown in FIG. FIG. 8 is a schematic cross-sectional view illustrating a state before the communication terminal rotating device is rotated, and FIGS. 8 and 9 are schematic cross-sectional views showing the rotating state of the mobile communication terminal rotating device shown in FIG. 1.

Normally, the display member D of the mobile communication terminal is closed to the main body B in a vertical state as shown in FIG. 5.

When the user rotates the display member D in either direction, the swing member 100 coupled to the display member is rotated about the central axis 110 so that the display member D is opened as shown in FIG. 6. .

In more detail, this process, as shown in Figure 7, the slide block 410 is subjected to the elasticity of the spring 420 by pressing a predetermined elastic force between each projection 212 of the cam 210, the display member The 130 maintains the state closed in the main body in a state in which the vertical direction is long with respect to the main body. Subsequently, when the user rotates the display member D in one of two directions, the swing member 100 along with the display member D rotates about the central axis 110 as shown in FIG. 8. In this process, each slide block 410 is pushed back to overcome the elasticity of the spring 420 by the protrusion 212 of the cam 210. Thereafter, as shown in FIG. 9, the slide block 410 presses the cam 210 again by the elastic restoring force of the spring 420 to maintain the display member D in an open state.

And as shown in FIGS. 7 to 9. When the swing member 100 rotates 90 ° in any direction about the central axis 110, the locking projections 216 formed on the first slide member 200 and the locking protrusion 114 formed on the central axis 110 are rotated. Contact causes the swing member 100 to no longer rotate.

Therefore, the display member D and the swing member 100 rotate only within a range of 90 ° in both directions.

When the display member D is rotated by 90 ° in both directions, the liquid crystal display of the display member D becomes long in the horizontal direction. In this state, the movie is viewed at a normal size through the LCD screen.

The operation of rotating the display member D back to the original state is performed in the reverse order to the above process.

Next, the configuration of the slide opening and closing device will be described.

The opening and closing device for opening and closing the display member of the mobile communication terminal from the main body is fixed to the main body, coupled to slide with the first slide member 200, the inclination point 520a in which the inclination direction is reversed is one or more in the center region The first slide member 200 includes a second slide member 500 having an inclined surface 520, an elastic member that generates an elastic force in a direction orthogonal to a direction in which the first slide member 200 moves, and the elastic member. A binding member for fixing onto the upper surface, and one or more slip members receiving the elastic force of the elastic member and transferring the same to the inclined surface 520 so that the first slide member 200 slides from the second slide member 500. .

This will be described in more detail with reference to FIGS. 1, 2 and 10 as follows.

The second slide member 500 is fixed to the main body (not shown) of the mobile communication terminal and slides in one direction with the first slide member 200. The at least one guide rod 510 is the second slide member 500. It is fixed in the direction of movement, the first slide member 200 is formed with a guide ball 220 to be slidably coupled to the guide rod 510, by the coupling of the guide rod 510 and the guide ball 220 The first slide member 200 and the second slide member 500 are slidably coupled. At each end of both sides of the second slide member 500, fitting holes 512 for fitting the guide rods 510 are formed, and both ends of the guide rods 510 are coupled to the fitting holes 512.

One inclined surface 520 is formed at a symmetrical position of the second slide member 500, and the distance between both inclined surfaces 520 is minimized at the inflection point 520a.

The binding member and the slip member are each paired in a symmetrical position.

The elastic member is made of torsion spring 600.

The binding member includes one or more links 700 whose one end is axially supported by the first slide member 200 and the other end is axially supported by the end of the elastic member to support the elastic member to the first slide member 200. Each link 700 is rotatably mounted to the first slide member 200 by a first central axis 710. The first central axis 710 is the center of rotation of the link 700.

In order to install the torsion spring 600, each end portion of the torsion spring 600 is bent to form a ring 610, and each link 700 forms a protrusion 720 coupled to the ring 610. . By coupling each protrusion 720 to each ring 610, each end of the torsion spring 600 is rotatably connected to the link 700.

The slip member consists of a roller 800 which is axially supported by the link 700 and rolls on the inclined surface 520 of the second slide member 500. The roller 800 is rotatably installed on the link 700 by the second central axis 730. Since the roller 800 rolls on the inclined surface 520, the friction force may be minimized.

When the roller 800 is in a position where the roller 800 is closed with respect to the inflection point 520a on the inclined surface 520, a force is applied to the second slide member 500 in the closing direction, and the roller 800 is in the inflection point 520a on the inclined surface 520. In the open position with reference to), a force is applied to the second slide member 500 in the open direction.

Semicircular first fixing grooves 522 and second fixing grooves 524 are formed at both ends of each inclined surface 520 to generate a stopping force when the second slide member 500 is in the closed position and the open position. .

Such a mobile terminal has a function of turning on the LCD screen when the display member D is opened on the main board of the main body B, and turning off the LCD screen when the display member D is closed on the main body B. Set.

The operation of the slide opening and closing device of the mobile communication terminal having the above structure will be described.

FIG. 10 is an exploded perspective view showing a slide opening and closing device of the mobile communication terminal shown in FIG. 1, FIG. 11 is a plan view of the slide opening and closing device shown in FIG. 10, and a slide opening and closing device shown in FIG. 10. Is a plan view in the direction of moving in the open direction, FIG. 13 is a plan view of the slide opening and closing device shown in FIG. 10 to the open position, and FIG. 14 is a perspective view of the mobile communication terminal shown in FIG. to be.

First, as the mobile communication terminal is closed, as shown in FIG. 11, the first slide member 200 coupled to the display member D is pushed in one direction on the second slide member 500.

In this case, the link 700 receiving the elastic force of the torsion spring 600 supported by the first slide member 200 transmits the elastic force to the roller 800, and the roller 800 is coupled to the first fixing groove 522. To suppress the flow of the first slide member 200.

In this state, when the display member D is pushed by hand to open the terminal, the display member D and the first slide member 200 are slid upward based on FIG. 11. At this time, the first slide member 200 and the second slide member 500 are coupled through the guide rod 510, so that the first slide member 200 has a good linear motion.

When the first slide member 200 starts to open, both rollers 800 are rolled off the first fixing grooves 522 on both inclined surfaces 520. Initially, the distance between the two inclined surfaces 520 is gradually narrowed, so that the roller 800 compresses the link 700 and the torsion spring 600. Since a predetermined resistance force is generated in this process, the user must move the first slide member 200 by pushing the display member D until the roller 800 reaches the inflection point 520a.

When the roller 800 exceeds the inflection point 520a as shown in FIG. 12, the distance between the two inclined surfaces 520 gradually increases, and the torsion spring 600 expands. In this process, since the expansion force of the torsional spring 600 acts as a force pushing the first slide member 200 in the opening direction through the roller 800, the user has since the roller 800 passes through the inflection point 520a. Even if the display member D is not pushed, the first slide member 200 automatically moves to the open position.

When the display member D and the first slide member 200 are fully opened as shown in FIG. 13, the roller 800 is caught by the second fixing groove 524 again to generate a predetermined braking force.

Therefore, the first slide member 200 is to maintain the open state.

As shown in FIG. 14, when the display member D is opened, the keypad of the main body B is opened, and the LCD screen is turned on according to a preset function, so that the user can use a unique function of the terminal.

On the other hand, in order to close the mobile communication terminal in the open state of the display member (D), the user pulls the display member (D) by hand in the opposite direction as when opened. The closing operation of the display member D is performed in the reverse order of the opening operation.

First, as illustrated in FIGS. 19 to 22, when the display member D is slidably moved, the pressing piece 1040 protruding from the upper end side of the first slide member 200 is slidably moved to the seesaw 1020. In contact with the pressing piece 1024, the pressing piece 1024 of the seesaw 1020 is pressed. When the pressing piece 1040 presses the pressing piece 1024 of the seesaw 1020, the hinged seesaw 1020 and the seesaw guide 1010 are moved along the hinge to seesaw and the pressing piece 1024 of the seesaw 1020. On the opposite side of the protruding sisoribet 1022 is rotated. At this time, the seesaw spring 1030 installed between the seesaw 1020 and the seesaw guide 1010 is compressed. Subsequently, the sisoribet 1022 is rotated to protrude through the sisoribet through-hole 1050 of the second slide member 500. Then, when the user rotates the display member D counterclockwise, the braking groove 1060 formed on one side of the display member D is rotated to the sisoribet through-hole 1050 of the second slide member 500. The display member D is rotated 90 ° counterclockwise in a state in which one end of the protruding sisoribet 1022 and both ends of the semicircular brake groove 1060 are in contact with each other. Subsequently, even if the user applies a force to rotate the display member D 90 degrees in the counterclockwise direction, one end of the sisoribet 1022 and the braking groove 1060 is contacted and the display member D no longer rotates. .

In addition, when the user applies a force to slide the display member D while the display member D is rotated by 90 ° in either of two directions, the protruding sisoribet 1022 may cause the braking groove 1060. It does not slide in contact with the side wall.

Accordingly, in order to close the display member D, when the display member D is rotated in the opposite direction to coincide with the main body and the display member D is pulled by hand, the pressing piece 1040 of the first slide member 200 is pulled. The pressing piece 1024 is dropped while being pressed, and the seesaw 1020 rotates around the hinge by the elastic restoring force of the spring compressed between the seesaw 1020 and the seesaw guide 1010 to the sisoribet 1022. ) Is escaped from the sisori bet through hole (1050). Subsequently, the display member D may slide smoothly.
