SLIDE MODULE FOR CELLULAR PHONE WITH BUILT-IN KEY PAD}

The present invention relates to a slide module of a built-in mobile phone, and more particularly to a slide module of a built-in mobile phone in which the upper body with the image portion is rotated inclined after sliding in the horizontal direction with respect to the lower body with the keyboard portion. .

With the development of wireless communication technology, mobile phones have various functions, and various kinds of mobile phones also have a flip type, a folder type, a slide type, and the like.

In addition, today's mobile phones provide not only voice communication but also e-mail, Internet access, photography, gaming, and many other functions. Similarly, cell phones with built-in keypads with QWERTY keyboards are available.

Here, the QWERTY keyboard has a longer horizontal length than the vertical length, and thus, unlike a mobile phone which opens and closes the numeric keypad of the lower body while the upper body slides in the vertical direction, the QWERTY keyboard moves in the horizontal direction to open and close the QWERTY keyboard. Done.

It is slidably coupled.

The moving plate 100 is coupled to the upper body 10, and the upper body 10 also moves together with the sliding movement of the moving plate 100. In the state where the upper body 10 slides to open the keyboard unit 21, a portion of the lower surface of the moving plate 100 is exposed to the outside through the lower side of the upper body 10.

The guider 200 is disposed on the lower surface of the moving plate 100 and the U-shaped guide portion 210 is formed at both ends of the left and right sides.

The movable plate 100 is coupled to the guide groove 210a formed at the left and right ends of the movable plate 100 in the guide part 210 so as to be slid with respect to the guider 200.

The guider 200 is combined with the supporting portion 432 of the rotary support 430 to be described later to rotate upward according to the upward rotation of the rotary support 430, whereby the movable plate 100 and the upper body 10 Will rotate upward.

In the sliding process of the movable plate 100 with respect to the guider 200, the position where the upper body 10 opens the keyboard portion 21 or the keyboard portion 21 is closed to overlap the lower body 20. An elastic force is provided to be semi-automatically placed on the first elastic assembly 300. The elastic force is provided to the first elastic assembly 300.

The first elastic assembly 300 is in a position to slide or completely close the movable plate 100 so that the upper body 10 is in a position to completely open the keyboard portion 21 except for a dead point. It will slide to release.

The first elastic assembly 300 greatly affects the feeling of sliding when the mobile plate 100 is slid, and also greatly affects the appearance of the mobile phone 2 depending on whether it is exposed to the outside.

Therefore, it is preferable that the first elastic assembly 300 is formed to form a stable and smooth slide feeling, and not to be exposed to the outside, for example, the example shown in FIG. 4 may be presented.

One end of the first elastic assembly 300 is hinged to the upper surface of the movable plate 100, the other end is hinged to the hinge portion 211 is formed extending from the upper guide portion 210, the sliding of the movable plate 100 At the same time as the movement is rotated and compressed and the elastic force is accumulated and the dead point passes, the moving plate 100 is automatically moved in the sliding direction while restoring the shape by the restoring force.

The first elastic assembly 300 may be provided with one, it may be made of a pair installed symmetrically from side to side on the upper surface of the movable plate 100 as shown. When the pair is made of a movable plate 100 is provided with a symmetrical elastic force with respect to the guider 200, so that a more stable and smooth sliding movement is possible, thereby accompanying the upper body 10 and the lower body 20 It can cope with an increase in load. This is also true considering the durability of the first elastic assembly 300.

In addition, the first elastic assembly 300 is installed on the upper surface of the movable plate 100, that is, disposed between the upper body 10 and the movable plate 100 to block the exposure to the outside, whereby the mobile phone 2 ) Can improve aesthetics.

As a specific example of the first elastic assembly 300, as shown in Figure 4, the elastic body 310, the first spring 320 and the support frame 330 is included.

The elastic body 310 is composed of a pair of opposing to each other, each of the elastic body 310 is a slide bar 311 is formed on one side and the slide groove 312 is formed on the other side is slidingly coupled to each other.

In addition, both ends of the elastic body 310, that is, the end of each of the elastic body 310 is provided with a coupling hole 313 through the hinge to be hinged to each of the upper surface and the hinge portion 211 of the movable plate 100.

Each position of the movable plate 100 and the hinge portion 211 to which the coupler 313 is hinged is coupled to the uppermost side of the elastic body 310 or the whole of the rotation section according to the rotation of the first elastic assembly 300. To the bottom.

Any one of the elastic body 310 has a slide bar 311 is formed on one side and a slide groove 312 is formed on the other side, and the slide bar 311 and the slide groove 312 formed in any one of the other Correspondingly, slide grooves 312 and slide bars 311 are formed at one side and the other side, respectively.

Then, any one slide bar 311 is slidingly coupled to the other slide groove 312, the pair of elastic bodies 310 by the hinge coupling of the coupler 313 is not separated from each other while slidingly coupled Do not. In addition, the pair of elastic bodies 310 may vary in overall length while being narrowed or moved away from each other.

Each of the elastic body 310 has a pair of the slide bar 311 and the slide groove 312 is supported on each other in the sliding side, so as not only the external force acting in the sliding direction between the elastic body 310, but also the movable plate 100 The coupling sphere 313 that can cope with the external force acting in the sliding direction of the) more firmly to form.

In addition, when the first elastic assembly 300 is provided in pairs, the external force applied can be more effectively dispersed.

The first spring 320 is located inside the pair of elastic bodies 310 to act to push the elastic bodies 310 to both sides. In addition, the support frame 330 supports the first spring 320 to prevent the first spring 320 from remaining outside the elastic body 310.

As a specific example of the first spring 320 and the support frame 330, first, the first spring 320 is made of a coil spring 321 may be divided into two centered around the support frame 330, in this case, A plurality of coil springs may be provided one by one or two or more at both sides of the support frame 330. (In the drawing, an example in which two coil springs are divided into four is illustrated.)

The support frame 330 extends in the sliding direction of the elastic body 310 at both sides of the boundary portion 331 provided at the center to form a boundary of the divided coil spring 321 and the boundary portion 331 in the coil spring ( It may be composed of a support rod 332 is inserted into the 321.

It is preferable that the boundary part 331 is also supported by the elastic body 310 so that the coil spring 321 is supported while staying inside the elastic body 310. As an example of a structure in which the boundary part 331 is supported by the elastic body 310, support grooves 331a are formed at both ends of the boundary part 331, and both ends of the boundary part 331 are interviewed with each other. The support protrusions 314 are formed in the support grooves 331a by a predetermined length of the support protrusions 314 in the sliding direction of the elastic body 310 in each inner side, specifically, the inner side of the elastic body 310 in which the slide grooves 312 are formed. An example of the structure in which the boundary portion 331 is supported by the elastic body 310 as the () is inserted may be presented.

Since the length between the elastic body 310 is variable according to the sliding of the elastic body 310, each inner side of the elastic body 310, the both ends of the boundary portion 331 to be interviewed is slid with respect to the boundary portion 331, Therefore, the support protrusion 314 is formed by this sliding length. And since the support protrusion 314 is fitted into the support groove 331a, the boundary portion 331 is supported by the elastic body 310 in spite of the variable length of the elastic body 310 while preventing the departure from the elastic body 310. As a result, the coil spring 321 supported by the support rod 332 is also supported and stays inside the elastic body 310.

The support rod 332 is formed corresponding to the number of coil springs 321 provided, and is formed horizontally parallel to the sliding direction of the elastic body 310 and coinciding with the sliding surface thereof.

On the other hand, the coil spring 321 provided on the inside of the elastic body 310 is compressed in accordance with the variable length, because the length of the support rod 332 is not variable, it may be an obstacle to the variable length between the elastic body 310. have. Therefore, the inner part of the elastic body 310 that the end of the support rod 332 is in contact with the support rod 332 may be formed through the rod hole 315, whereby the elastic body 310 is narrowed with each other The coil spring 321 which is in contact with the inner surface of the elastic body 310 is compressed, but the support rod 332 inserted into the coil spring 321 in this compression process passes through the rod hole 315 to elastic body 310 Since it protrudes outward, it is not an obstacle to narrowing between the elastic bodies 310.

Referring to the process in which the elastic force is provided in the sliding plate movement process by the first elastic assembly 300 as follows.

When the user pushes the upper body 10 in the horizontal direction to open the keyboard portion 21, the moving plate 100 is guided by the guider 200, the sliding movement, in the process between the elastic body 310 As the distance is narrowed, the coil spring 321 located inside thereof is compressed. The support rod 332 protrudes outward from the elastic body 310 through the insertion hole.

The elastic body 310 tries to move away again by the restoring force of the compressed coil spring 321, and if the user pushes the upper body 10 until the dead point of the first elastic assembly 300, the coil spring thereafter. By the restoring force of 321, the automatic sliding movement of the movable plate 100 occurs to the position where the upper body 10 opens the keyboard portion 21.

In the case of pushing the upper body 10 in the opposite transverse direction to close the keyboard portion 21, the same elastic force providing process is made.

The second elastic assembly 400 moves upward of the movable plate 100 when the sliding movement in the direction in which the movable plate 100 opens the keyboard portion 21 by the first elastic assembly 300 is completed. It provides a rotational force to rotate.

As a specific example of the second elastic assembly 400, the fixing frame 410, the shaft 420, the rotation support 430, the torsion spring 440 and the locking means 500 is Examples included may be presented.

As will be described in detail below, FIGS. 3 and 5 illustrate that the second elastic assembly 400 is provided in pairs.

The fixing frame 410 is formed with bending walls 411 and 412 that are bent upwards at both ends, and through holes 411a and 412a are coupled to the bending walls 411 and 412 so that the shaft 420 described later is penetrated. Is formed.

In addition, a fixing plate 413 coupled to the lower body 20 is extended to one side of the fixing frame 410 so that the fixing frame 410 may be fixed to the lower body 20.

The shaft 420 is disposed while the two ends are rotatably coupled in the through holes 411a and 412a formed in the bent walls 411 and 412 to cross the bent walls 411 and 412.

Rotating support 430 is coupled to one side of the shaft 420 disposed between the bent walls 411 and 412, specifically, the rotation support 430 rotates together with the shaft 420 at one side of the shaft 420. Rotating arm 431 that is constrained and coupled to the shaft 420 is formed on one side, and the other side of the plate-shaped fixed to the back of the guider 200 to rotate to support the back of the guider 200 as the rotating plate rotates Support portion 432 is formed extending.

Therefore, when the rotary arm 431 rotates by the torsion spring 440 which will be described later, the shaft 420 bound to the rotary arm 431 is also rotated together, and is supported by the upward rotation of the rotary arm 431. As the unit 432 rotates together, the guider 200 rotates upwardly.

The torsion spring 440 is axially coupled to the other side of the shaft 420, which is a side of the rotation arm 431, and the torsion spring 440 is bent at one end and the other end of the torsion spring 440. It is fixed to one side of the wall 412, respectively.

Rotating support 430, by the locking means 500 to be described later, so that the guider 200 does not rotate and maintains a horizontal state until the sliding plate that the moving plate 100 opens the keyboard portion 21 is completed. Rotation is suppressed. Accordingly, in this state, the torsion spring 440 is already twisted and tensioned, that is, maintains a state in which the rotational force (restoration force) is accumulated, and the sliding movement of the movable plate 100 is completed to rotate by the locking means 500. Since the rotation of the support 430 is allowed to provide a rotational force to rotate the guider 200 upward.

The locking means 500 is a means for allowing the rotational force (restoration force) action of the torsion spring 440 as described above from the time when the sliding movement of the movable plate 100 is completed, and the specific work of the locking means 500. As an example, an example consisting of the second spring 510 and the locker 520 may be presented.

The second spring 510 is coupled to the portion of the shaft 420 protruding outward from one of the bent walls 411 and 412, and the annular portion 421 is formed at the end of the portion of the protruding shaft 420. It is formed to prevent the separation of the second spring 510. The annular portion 421 may be integrally formed at the end of the shaft 420 but may be formed of an E ring 422 fitted to the end of the shaft 420 as shown in FIG. 5, or may be formed on the E ring 422. In addition, a washer 423 may be further included between the E ring 422 and the second spring 510.

The locker 520 is coupled to the shaft portion 420 protruding to be disposed between the second spring 510 and the bent wall 411. Specifically, the locker 520 has a locker body 521 coupled to the shaft 420, a locking jaw 522 extending while being bent in an L shape at the upper end of the locker body 521, and the locker body 521. It may be formed of a locking plate 523 is formed to extend integrally from the side of the) and protrude upward to be caught by the protrusion 101 to be described later.

The rocker body 521 is rotatably coupled to the shaft 420, but is not affected by the rotation even if the shaft 420 rotates together with the rotation of the rotary arm 431. Then, it is elastically pressed by the second spring 510 and is in close contact with the bent wall 411.

The locking jaw 522 is formed to be bent in an L-shape at the upper end of the rocker body 521, so that the end of the locking jaw 522 can be protruded into the bending wall 411 in which the rotary arm 431 is placed. A groove 411b corresponding to the locking jaw 522 is formed at the upper end of the bending wall 411.

Locking jaw 522 is a rocker body 521 is in close contact with the bent wall 411 as the protrusion protrudes into the bent wall 411 through the groove portion 411b and the rotation is in close contact with the inside of the bent wall 411 The upper end of the arm 431 is placed to suppress the upward rotation of the rotary arm 431. The rotation arm 431 cannot rotate unless the locking step 522 is pushed outward from the groove 411b. Therefore, despite the rotational force of the torsion spring 440, until the sliding plate 100 completes the sliding movement in the direction of opening the keyboard 21, the force that the rotating arm 431 tries to rotate upward is the movement plate 100. In this way, the upward rotation force does not interfere at all with the sliding movement in the horizontal direction.

The locking plate 523 is integrally formed so as to protrude upward in the lateral direction of the rocker body 521, and the protrusion 101 for outward rotation of the locking plate 523 protrudes at the corner of the movable plate 100. Is formed.

The protrusion 101 is rotated outward by pushing one side of the locking plate 523 when the sliding plate 100 is slid in the direction in which the moving plate 21 is opened. As the locking plate 523 rotates outward, the locking jaw 522 formed at the upper end of the rocker body 521 also retreats from the inside of the bending wall 411 while overcoming the elastic force of the second spring 510. The locking of the upper end of the rotating arm 431 by the 522 is released until the rotation of the rotating arm 431 is allowed.

And, the protrusion 101 is preferably formed with an inclined surface (101a) on one side so as to naturally push one side of the locking plate 523 when the sliding movement of the movement plate 100 is completed.

On the other hand, the second elastic assembly 400 may be further provided with means for limiting the upward rotation range of the rotary support 430.

For example, the locking foot 431a may protrude from the lower side of the rotating arm 431. When the locking foot 431a is rotated upward by a desired angle, the locking foot 431a is engaged with the bottom surface of the fixing frame 410 to serve as a brake to suppress further upward rotation of the rotation support 430. .

As the rotation range limiting means other than the locking foot 431a, or as a means for limiting the rotation range while being provided with the locking foot 431a, the second elastic assembly 400 may further include a stopper means 600. Can be.

The stopper means 600 may be provided at an outer side of the bending wall 412 opposite to the bending wall 411 in which the second spring 510 and the locker 520 described above are disposed. An example may include a third spring 610, a first cam 620, and a second cam 630 that are sequentially coupled from the end portion of the shaft 420 protruding outward.

A third spring 610 may be axially coupled to the protruding shaft 420, and an annular portion 421 may be formed at an end of the shaft 420 so that the third spring 610 is not separated from the shaft 420. .

Between the third spring 610 and the bent wall 412, the first cam 620 and the second cam 630 are axially coupled to the shaft 420 in order from the third spring 610.

The first cam 620 is restrained and coupled to the shaft 420 so as to rotate together with the shaft 420, and a locking protrusion 621 protrudes from one side of the bending wall 412.

The second cam 630 is disposed between the first cam 620 and the bent wall 412 and axially coupled to the shaft 420, and is coupled to the shaft 420 so as to rotate. However, the bending wall 412 is restrained and positioned to be restrained from rotation. For this purpose, an upper portion of the second cam 630 is formed with an L-shaped fitting portion 632, and an upper end portion of the bending wall 412. An example may be provided in which fitting grooves 412b corresponding to the protrusions are formed to be fitted to each other. In addition, a locking groove 631 is formed on one side of the second cam 630 facing the first cam 620 such that the locking protrusion 621 is caught.

The locking groove 631 is formed at a position where the locking protrusion 621 may be engaged when the rotation support 430 is rotated at a desired angle. Not only this position but also the position corresponding to the locking protrusion 621 at this time so that the locking protrusion 621 can be engaged even in a state in which the moving plate 100 is rotated downward in order to return the upper body 10 to its original position. Can be.

The above-described second elastic assembly 400 may be provided to rotate to support one point of the guider 200, but to support the left and right sides of the guider 200 to rotate, that is, the movable plate ( It may be made of a pair coupled to the lower body 20 while being provided symmetrically as shown to support the left and right sides of the 100 to rotate.

Paired second elastic assembly 400 may be a more preferred embodiment in terms of durability of the second elastic assembly 400, and the stable rotation or suppression of rotation, and limit of the rotation range is achieved.

The upward rotation process of the moving plate 100 by the second elastic assembly 400 will be described with reference to FIG. 6 as follows.

As shown in FIGS. 6A and 6B, when the user applies the external force to move the upper body 10 in the direction in which the keyboard part 21 is opened, the moving plate 100 is slid together. .

When the sliding movement of the movable plate 100 is completed, the projection 101 rotates by pushing the locking plate 523 outward and the locking jaw 522 is bent along the outward rotation of the locking plate 523. Retreat from the inside to release the locking at the upper end of the rotary arm 431.

6 (c) as soon as the rotary arm 431 is rotated upward by the torsion spring 440, the back of the guider 200 is supported by the support portion 432 that rotates with the guider 200 is rotated upward. As the guider 200 rotates upward, the moving plate 100 also rotates upward.

At this time, the rotation of the rotating arm 431 and the shaft 420 and the first cam 620 constrained and coupled to the shaft 420 is also rotated together, when the rotation of the movable plate 100 is completed at a desired predetermined angle The locking protrusion 621 of the first cam 620 is engaged with the locking groove 631 of the second cam 630, and at the same time, the locking foot 431a is caught on the bottom surface of the fixing frame 410 to stop the rotation.

In the process of repositioning the upper body 10 so that the keyboard portion 21 is closed again, the user applies an external force to rotate the upper body 10 downward so that the upper body 10 is horizontally positioned. In this process, the movable plate 100 and the guider 200, and the rotating arm 431 is rotated downward at the same time, the shaft 420 and the first cam 620 also rotates in the same rotation direction in accordance with the rotation of the rotating arm 431.

In the state where the movable plate 100 is placed horizontally, the locking protrusion 621 of the first cam 620 is engaged with the locking groove 631 of the second cam 630 formed correspondingly.

When the user slides the upper body 10 in the horizontal direction in which the keyboard portion 21 is closed in this state, the protrusion 101 of the movable plate 100 is separated from the locking plate 523 and the locking plate 523 is removed. ) Is returned to its original position, and as the locking plate 523 returns, the locking jaw 522 protrudes into the bent wall 411 while passing through the groove 411b. And while the upper end of the rotary arm 431 is caught by the protruding locking step 522, even if the user does not apply the external force downward, the upward rotation of the rotary arm 431 is suppressed. That is, the rotational force by the torsion spring 440 will not interfere anymore.

The user only applies the external force in the horizontal direction, the external force only needs to be applied to the dead point of the first elastic assembly 300, after which the upper body 10 automatically returns to its original position.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It is not limited.
