Elastic device for sliding module installed in sliding type mobile phone {Spring Device for Sliding Module of Cell Phone}

The present invention relates to an elastic device for a sliding module installed in a mobile phone of the sliding type, in more detail, it is possible to improve the compressive force and the restoring force by using a plurality of very thin plate springs, both ends of a plurality of leaf springs The present invention relates to an elastic device for a sliding module installed in a mobile phone of a sliding type that ensures high reliability by joining and joining a flat portion of a hinge part in a flat state.

In general, in order to use services such as broadcasting and communication wirelessly while moving in a place other than a fixed location, mobile terminals such as mobile phones, PDAs, notebooks, and DMB phones are frequently used. Conventional portable terminals are one of the essential necessities that are indispensable in order to enjoy the convenience of life according to the development of the information technology industry, and the mobile phones are widely distributed to elementary, middle and high school students and the elderly.

In the portable terminal, various methods are applied to open and close the cover, which can be divided into a hinge method, a slide method, and a swing method.

Among them, the portable terminal that opens and closes the cover by a slide method is one of the most applied methods in recent years because of various advantages such as easy use, less trouble, and a stylish design.

The basic structure of the mobile terminal for opening and closing the cover by a conventional slide method is a configuration for sliding the cover installed with the display portion up and down from the main body, the keypad is installed, the conventional sliding type for a mobile terminal of various structures based on the basic structure Switchgear is manufactured around each manufacturer.

For example, the conventional sliding module for a mobile terminal has a first sliding member which is formed in a plate shape and is fixed to the main body of the mobile terminal and formed with guide protrusions at both corners, and is formed in a plate shape and on the cover of the mobile terminal. The second sliding member is fixed and the rail member having a rail groove having a guide groove of the first sliding member is slidably assembled at both corners, and the sliding of the second sliding member to be made more easily and smoothly Both ends are rotatably coupled to and supported by the first sliding member and the second sliding member.

In the conventional elastic device, as the user applies the force to the cover until the first sliding member is slid for a certain period in the open or closed state of the mobile terminal, the rest of the cover is naturally moved by the elastic restoring force. It is composed. In the conventional sliding cover opening and closing device for a mobile terminal configured as described above, since the sliding contact is made between the first sliding member and the second sliding member when the cover is opened and closed, the friction is increased when the portable terminal is large or has a large load.

That is, since the contact area between the guide protrusion of the first sliding member and the rail groove of the second sliding member is increased or the frictional force is increased, the opening and closing operation of the cover tends to be poor.

In addition, the conventional sliding cover opening and closing device for a mobile terminal uses a coil spring or a torsion spring as an elastic device, and the first sliding member and the second sliding member come into contact with the first sliding member and the second sliding member due to the sag of the intermediate part. There was a problem that damage the sliding member.

It is an object of the present invention to provide an elastic device for a sliding module that is installed in a sliding type mobile phone.

In order to achieve the above object, the elastic device for a sliding module installed in the mobile phone of the sliding type according to the present invention is configured so that both ends have the same radian value, but the other parts except for both ends have different radians. .

An elastic device according to the present invention is an elastic device composed of at least one linear leaf spring, each end of the leaf spring is formed with a hinge connection,

The hinge connection portion is characterized in that bonded to the bottom surface of the leaf spring,

The hinge connection portion is characterized in that the groove is formed,

The upper reinforcement plate is characterized in that the upper portion of the leaf spring,

The lower reinforcement plate is characterized in that the lower portion of the leaf spring,

The hinge connection portion is characterized in that the separation and replacement from the leaf spring,

The position of the groove of the hinge connection portion is characterized in that the deformation,

Two or more leaf springs are installed, and the radian value of the leaf springs installed on the upper is smaller.

In the sliding type mobile phone, when one of the leaf springs 312, 314, and 316 of the elastic device is broken or cut while the elastic device is compressed and restored while the user is using the sliding mobile phone, the cut spring is cut. It is easy to cause the FPCB to be damaged, which causes the phone to break down.

In the eighteenth exemplary embodiment of the present invention, the upper and lower reinforcing plates 310 and 318 are installed at both ends of the leaf springs 312, 314 and 316 so that the elastic device is compressed and restored. Even if any one of the springs 312, 314, and 316 is broken or cut, the broken leaf spring is located inside the upper and lower reinforcement plates 310, thereby minimizing the problem of damaging the FPCB installed inside the mobile phone. do.

In addition, depending on the model of the mobile phone, it is necessary to produce a mobile phone having a long dead distance X and a long sliding distance Y. However, in the case of having a short dead point distance X, it is difficult to produce an elastic device having a long sliding distance Y.

If the dead center distance X constitutes a product that is too short, if the hinge connection 20 at both ends of the elastic device is compressed to the dead center distance X, the elastic device is compressed beyond the restorable range. This is because the leaf springs 10, 12, and 14 lose their restoring force, and thus, a problem arises that it is difficult to perform the function as a spring anymore. In the present invention, the above problem is achieved by modifying the hinge connection portion (20).

In addition, since an extremely thin plate spring can be used, ultimately, the thickness of the mobile phone can be manufactured to have a slimmer mobile phone. Recently, the end producers of mobile phones such as Samsung, LG, etc. have been demanding parts makers 200,000 times of reliability for compression and restoration of elastic devices.

Advantages, features, preferred embodiments, and the like of the present invention are described in detail below with reference to the accompanying drawings.

1 is a front view and a side view of a state in which no tension is applied and a state in which tension is applied to the elastic device for a sliding module installed in the mobile phone of the sliding type according to the first embodiment of the present invention.

Referring to Figure 1, the elastic device according to the present invention includes three leaf springs (10, 12, 14) made of a metal for manufacturing a conventional spring and one hinge connection portion 20 at each end, respectively; Make a configuration. The hinge connector 20 according to the present invention is composed of a sus (SUS) -based metal.

Each hinge connector 20 of the present invention is rotatable by using a conventional connecting means such as rivets, respectively, to the slider and the frame of the sliding module consisting of a slider and a main body frame which is installed in the sliding type mobile phone To be connected.

The three leaf springs 10, 12, 14 and the hinge connection portion 20 according to the present invention is configured to be coupled to each other through laser welding, spot welding, argon welding or metal bonding.

Reference numeral 16 shows the configuration of the joint separation section 16 in which the three leaf springs 10, 12, 14 are directly out of the portion joined to the hinge connection 20. It is configured to have a smaller R (radius) as viewed from the junction separation portion 16 toward the outside with respect to the innermost leaf spring (14). That is, the size of R in the junction separation unit 16 is configured as the leaf spring 14> leaf spring 12> leaf spring 10.

The reason why R should be constructed such as leaf springs (14)> leaf springs (12)> leaf springs (10) is that, when both hinge portions (20) are bent inward, Since the springs 10, 12 and 14 have different R values as described above, even when the plate springs 10, 12 and 14 are bent inwardly as shown in (c), the respective leaf springs 10, 12 and 14 do not overlap each other and have a constant interval. It can maintain better shrinkage and maintain strong restoring force.

If each of the leaf springs 10, 12, 14 does not have a different configuration of "R" as described above, the three elastic springs of the present invention will have three leaf springs 10, 12, 14 in compression. They overlap each other, and in this case, the restoring force is reduced.

Currently, the degree of reliability required in the sliding cell phone industry for the elastic device is that the elastic device maintains the restoring force without losing the restoring force so that the proper sliding is possible even if the elastic device repeats compression restoration due to the sliding of about 200,000 times. Thus, in order to meet this demand, each of the leaf springs 10, 12, 14, like the junction separation 16 in the value of R, the leaf spring 14> leaf spring 12> leaf spring 10 R must be configured as

In addition, the two ends of the three leaf springs (10, 12, 14) flatly overlapping each other in parallel with the parallel surface of the hinge connecting portion 20 by laser, spot welding, metal bonding or argon welding to 200,000 times The contraction of the three leaf springs (10, 12, 14) and the hinge connection portion 20 can be maintained even in the contraction recovery.

Referring to FIG. 18, each of the hinge connecting portions 20 at both ends of the elastic device according to the first embodiment shown in FIG. 1 is connected to the connecting portion 212 of the slider 210 and the connecting portion 202 of the frame 200. Each is rotatably connected.

The connection between the hinge connecting portion 20 of the elastic device and the connecting portion 212 of the slider 210 and the connecting portion 202 of the frame 200 may be rotatably connected to each other by existing connecting means such as rivets. .

FIG. 18B shows a state in which both ends of the elastic device according to the first embodiment are compressed as much as possible. In this case, the elastic device corresponds to a dead point section in which the force is horizontally applied to the left and right and the frame 200 does not exert a force to slide up and down the slider 210.

When the elastic device is compressed to the maximum as shown in (b), the distance between the center and the center of the groove of the hinge connecting portion 20 is referred to as 'dead center distance: X', and the frame 200 follows the slider 210. The maximum sliding distance is called 'sliding distance: Y'.

As a factor for determining the range of the maximum compression that the leaf springs (10, 12, 14) according to the present invention can be restored to its original state, the material of the leaf spring will be occupied a lot, but in the present invention the leaf springs (10, 12) , 14) The elastic device was manufactured to have only the dead center distance X of the minimum distance and the sliding distance Y of the maximum distance by deforming only the hinge connecting portion 20 under the premise that they have the same material.

The configuration of the elastic device according to the present invention for achieving this feature is described in detail in the drawings of FIGS. 21 to 28.

Depending on the model of the mobile phone, it is necessary to produce a mobile phone having a long dead distance X and a long sliding distance Y. However, in the case of having a short dead point distance X, it is difficult to produce an elastic device having a long sliding distance Y.

If the dead point distance X constitutes a product that is too short, if the hinge connection portion 20 at both ends of the elastic device is compressed to the dead point distance X, the elastic device is compressed beyond the restorable range. This is because the leaf springs 10, 12, and 14 have lost the restoring force, and thus, a problem arises that it is difficult to perform the function as a spring anymore.

In the present invention, the above problem is achieved by modifying the hinge connection portion (20). Description of this will be described in detail with reference to FIGS. 21 to 28.

20 is an operation diagram illustrating a state in which the elastic device for a sliding module according to the seventeenth embodiment of the present invention shown in FIG. 17 is installed and operated in a mobile phone sliding hinge.

In the case of FIG. 20, there is an advantage in that the dead point area is not easily generated.

21 and 22 illustrate a state in which tension is not applied and a state in which tension is applied to an elastic device for a sliding module installed in a mobile phone of a sliding type according to an eighteenth embodiment of the present invention and a modification thereof.

Referring to FIG. 21, (a) is a front view of a state in which no external force is applied to the elastic device according to the eighteenth embodiment of the present invention, and (c) is a view according to the eighteenth embodiment of the present invention. The front view of the external force applied inwardly to the hinge connecting portion 370 of both ends of the elastic device is shown. (B) and (c) are side views of (a) and (b), respectively.

The elastic device of the eighteenth embodiment corresponds to a modified example in which plate springs corresponding to the upper and lower reinforcing plates 310 and 318 are further coupled to the elastic device of the fifth embodiment shown in FIG.

Since the upper and lower reinforcement plates 310 of the present invention have a configuration that is considerably longer than the leaf springs 312, 314 and 316, under the same material, the upper and lower reinforcement plates 310 may be smaller than the leaf springs 312, 314 and 316 during compression of the elastic device. It is difficult to break because it receives less tension.

Referring to FIGS. 21 and 22, in the present invention, only the shape of the hinge connecting portion 370 is modified to change the dead center distance X of FIG. 18B without changing the material of the leaf springs 312, 314, and 316. The compression range of the corresponding elastic device can be adjusted.

If you first organize terms,

A: distance from the hinge connecting portion 370 before deformation, from the bottom leaf spring 316 to the center of the groove of the hinge connecting portion 370,

A ': in the deformed hinge connection 374, the distance from the bottom leaf spring 316 to the center of the groove of the hinge connection 374,

B: the distance between the groove and the groove of each hinge connection 370 during compression of the elastic device according to the eighteenth embodiment

B ': distance between the groove and the groove of each hinge connection 370 when compressing the elastic device having the deformed hinge connection 374 as shown in FIG. 21 (b).

That is, in the hinge connection portion 374 deformed as shown in FIG. 22, a groove of the hinge connection portion 374 is formed below the extended virtual line of the bottom leaf spring 316, and the bottom leaf spring 316 is formed. ) Extends the length A 'from the hinge connection portion 374 to the center of the groove in the downward direction, even if the elastic device according to the eighteenth embodiment is compressed to the same extent as in FIG. Shorter than B Therefore, even if the dead point distance X of FIG. 18 (b) is shorter but the elastic device according to the present invention is mounted on the sliding hinge having the same sliding distance Y, the material of the leaf springs 312, 314, and 316 is better restored. Installation is possible without deformation.

23 and 24 illustrate a state in which tension is not applied and a state in which tension is applied to an elastic device for a sliding module installed in a sliding type mobile phone according to a nineteenth embodiment of the present invention and a modification thereof.

Referring to FIGS. 23 and 24, the elastic device of the nineteenth embodiment is a modification in which the springs corresponding to the upper and lower reinforcement plates 310 and 318 are further coupled one by one to the elastic device of the first embodiment shown in FIG. 1. This is an example.

In the sliding type mobile phone, when one of the leaf springs 312, 314, and 316 of the elastic device is broken or cut while the elastic device is compressed and restored while the user is using the sliding mobile phone, the cut spring is cut. It is easy to cause a problem of damage to the FPCB, which causes circuit failure of the mobile phone.

In the nineteenth embodiment of the present invention, the upper and lower reinforcement plates 310 and 318 are connected to both ends of the leaf springs 312, 314 and 316 and installed up and down, so that the elastic device is compressed and restored. Even if any one of the leaf springs 312, 314, and 316 is broken or cut, the broken leaf spring is located inside the upper and lower reinforcement plates 310, thereby minimizing the problem of damaging the FPCB installed inside the mobile phone. Ha ha.

Referring to FIG. 24, the dead point of FIG. 18B is maintained while the same sliding distance Y is maintained without changing the material of the leaf springs 312, 314, and 316 by changing only the shape of the hinge connection portion 376. The compression range of the elastic device corresponding to the distance X can be shortened.

If you first organize terms,

C: distance from the hinge joint 372 before deformation to the center of the groove of the hinge joint 372 at the bottom leaf spring 316,

C ': distance from the deformed hinge connection 376 to the center of the groove of the bent hinge connection 376 in the bottom leaf spring 316,

D: Distance between the groove and the groove of each hinge connecting portion 372 during compression of the elastic device according to the nineteenth embodiment

D ': distance between the groove and the groove of each hinge connection 376 when compressing the elastic device having the modified hinge connection 376 as in Fig. 23 (c).

That is, in the hinge connection portion 376 deformed as in FIG. 24, the length C 'from the bottom leaf spring 316 to the center of the groove of the hinge connection portion 376 is the virtual value of the leaf spring 316. If it extends below the extension line, D 'becomes shorter than D even if the elastic device according to the nineteenth embodiment is compressed to the same extent as in Fig. 23C. Therefore, even when the elastic device according to the present invention is mounted on the sliding hinge having a shorter dead distance X of FIG. 18 (b) while maintaining the same sliding distance Y, without changing the traits of the leaf springs 312, 314, 316. Installation is possible.
