Apparatus for operating bodies of a slide type cellular phone}

The present invention relates to a mobile phone in which the subbody slides with respect to the main body, and more particularly, a sliding type mobile phone in which the subbody smoothly slides in the longitudinal direction of the mobile phone with respect to the main body using a link and a tension spring. The type of portable wireless terminal (hereinafter referred to as a cellular phone) can be classified into a bar type, a flip type, and a folder type mobile phone according to the appearance. The bar-type mobile phone is a type in which a data input / output means and a handset are mounted in a main body housing, and a keypad, which is a data input means, is exposed at all times, which may cause a malfunction and secure the distance between the handset and the handset. Due to the problem, there is a limit to miniaturization. A flip type mobile phone has a main body, a flip, and a main body and a flip that connect the flip. It consists of a hinge module (data module), the data input and output means and the handset is installed in the main body, the flip can cover the keypad, which is the data input means to prevent malfunction, the flip-type mobile phone also includes the transmitter and the receiver Due to the problem of securing distance, there is a limit to the miniaturization. The folder-type mobile phone is composed of a main body, a folder, and a hinge module for rotatably connecting the main body and the folder. In the state of being in close contact with the main body, it is possible to prevent malfunction of the keypad in the call standby mode, and in the call mode, the folder can be opened to secure a sufficient distance between the talker and the talker, which is advantageous in miniaturization. Or clamshell phone hinge module for rotatable coupling of a flip or folder to the body When the flip or folder rotates from the main body more than a predetermined angle, the force is provided in the open direction even if no more force is applied, and below that angle, the force is provided in the direction close to the main body. As the sub-body slides on the main body to open and close the sliding type mobile phone to open and close the keypad installed on the main body as shown in Figure 1 is a new trend is gradually commercialized, the sliding type mobile phone 1 is shown in FIG. As shown, the sub-body 2 is opened and closed by sliding in the direction of the arrow based on the main body 3. An example of an apparatus for driving the body of the sliding-type mobile phone shown in FIG. Nos. 308165 and 319967, which use only two torsion springs. It was the one to slide against the probe body in the main body.

However, the utility model proposals use two torsion springs to slide the subbody with respect to the main body. When the subbody is up / down with respect to the main body, the subbody is moved to 1/2 position on the main body. When the opening or closing point is reached, the direction of the pressing force of the torsion spring is changed drastically, and the subbody slides violently on the main body toward the fully open or closed position. The reason for this is that the resilience of the torsion springs is strong when the ends of the torsion springs are retracted and inflated. Not only will it come down by its own weight, but it will cause a break in the currency. There was a problem that the power is discharged because the sub-body is open when you put in the money.

The present invention is devised to solve the above problems, and an object of the present invention is to replace the sub-body by using a link and a tension spring, instead of using the conventional two torsion springs as a driving force for sliding the sub-body. The present invention provides a body driving device of a sliding type mobile phone which allows a smooth sliding operation when the main body is slid in the longitudinal direction of the mobile phone. Therefore, the present invention provides a linking and tension spring in harmony, so that when the subbody is slid on the main body. No sliding noise occurs in the fully open or fully closed position, and when the subbody slides in the longitudinal direction of the terminal with respect to the main body, the tension spring maintains a constant elasticity at one end of the link so that smooth sliding operation can be performed. Can and also long term Even with the advantage that it does not flow the phenomenon that the sub-body, optionally in the fully closed or fully open position of the sub-body is not generated.

It is preferable that the tension springs are accommodated in the grooves and impart a tension force that pulls the other end of the link toward the first position of the working groove. However, the tension springs used in the present invention can be replaced with a compression spring, This compression spring is received in the actuation groove to force the other end of the link toward the first position of the actuation groove. In addition, according to the present invention, a torsion spring for preventing the sliding of the sliding plate by the spring during the sliding of the sliding plate may be used auxiliary for the purpose of the balance of the bar, which is the When sliding, the spring pulls or pushes one end of the link elastically in the working groove so that one side projection of the sliding plate can slide in close contact with the guide groove of the fixed plate, thereby allowing the torsion spring to balance the force. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 shows an exploded perspective view of the body driving device of the mobile phone according to an embodiment of the present invention, the present invention is a sub-body in which the fixing plate 20 is formed with two guide grooves 21 on the side (2) and the main body 3 to which the sliding plate 30 to be described later is fixed so that the subbody 2 slides in the longitudinal direction with respect to the main body 3.

As shown in FIGS. 2 and 3, the sliding plate 30 is fixedly installed in the main body 3 in a suitable manner and is coupled to the guide grooves 21 of the fixing plate 20 to allow the sliding guide protrusions 31 to slide. And a working groove 32 to allow horizontal movement of the link 40 to be described later.

One end of the link 40 is rotatably fixed to the fixing plate 20 by a hinge shaft 41, and a bearing 42 mounted to the other end of the link 40 is fixed by a fixing pin 43. In addition, the fixing pin 44 is fixed to one side end of the spring 60 to be described later is held. Therefore, the bearing 42 installed at the other end of the link 40 is movable horizontally in the operating groove 32 of the sliding plate 30, so that the link 40 at the time of opening or closing the subbody 3 is closed. ) Rotates about its hinge axis 41 so that the other end of the link 40 is horizontally moved in the operating groove 32 of the sliding plate 30 to slide the sliding plate 30. However, in the present invention, the main role of sliding the sliding plate 30 is a tension spring 60, which is a link 40 when a user of the mobile phone pushes up or pushes the subbody 2 down. As well as the function of allowing the other end of the resilient horizontal movement in the operating groove 32 of the sliding plate 30, as well as to prevent flow in the initial position of the other end of the link 40 as will be described later In other words, when the subbody 2 is opened or closed, the spring 60 has a pressing force on the other end of the link 40 toward the first position (as shown in Fig. 3) of the working groove 32. Bar 60, the spring 60 is in communication with the working groove 32 but is accommodated in the elongated groove (32a) narrower than the working groove 32, the other end of the link 40 is made of the working groove (32) It is preferable that the tension spring impart a tension force to be pulled toward one position. On the other hand, as in the other embodiment of the present invention shown in Fig. 8, the compression spring 160 may be used, and the compression spring 160 is It is housed in the working groove 32 and serves to impart a repelling force to push the other end of the link 40 toward the first position of the working groove 32. Such tension as can be seen in Figures 3 and 8. The springs 60 and 160 are provided with a tension force at the other end of the link 40 when the subbody 2 is opened and closed by a user. The first position of the operation groove 32 is provided at the other end of the link 40 before and after the opening of the subbody 2 and at the same time as the sliding plate 30 is smoothly provided by providing elasticity such as axial force. The tension springs 60 and 160 thus serve as torsion springs as in the above-described prior art. Is a completely different structure and function. On the other hand, the torsion spring 50 for preventing the sliding phenomenon of the sliding plate 30 by the spring 60 during the sliding of the sliding plate 30 is assisted for the purpose of balance of force. The bar 60 may be used as the spring 60 is elastically pulled the other end of the link 40 in the operation groove 32 when the sliding plate 30 slides. (31) (protrusion on the right in Fig. 4) is in close contact with the one side guide groove 21 (guide groove on the right in Fig. 4) of the fixed plate 20, so that the slide of the torsion spring 50 In order to balance the force to the force to the sliding to the other side. In other words, the torsion spring 50 is fixed to the sliding plate 30, the spring pinning pin 51 and one side of the fixing plate 20 Mounted on the fixing hole 22 to balance the force at the time of engagement between the projection 31 of the sliding plate 30 and the guide groove 21 of the fixing plate 20 when the subbody 2 is opened and closed. When the subbody 2 is completely overlapped with the main body 3 when the subbody 2 is completely overlapped with the main body 3, the tensioning force of the tension spring 60 is used. Free end of link 40 as shown in 5b It is located in the first position (left position) of the additional operation groove 32. In this state, the user can move the subbody 2 to the main body 3 with respect to the main body 3 in order to use the cellular phone. In the upward direction, the free end (the other end) of the link 40 gradually moves to the right as the subbody 2 moves upward (opening), so that the tension spring 60 increases. When the fixed plate 20 fixed to 2) is moved upward with respect to the sliding plate 30 and the subbody 2 slides about halfway between the main body 3, the free end of the link 40 is operated by a groove ( It is located in the second position (right position) of 32, the user pushes further the sub-body 2 in the open direction to change the direction of the pressing force of the tension spring 60, accordingly the tension spring ( 60, the free end of the link 40 is shown in FIG. As described above, the sub-body 3 can be completely opened from the main body 2 by returning to the first position of the operation groove 32. On the other hand, when the sub-body 2 is to be closed after the use of the mobile phone, As shown in FIG. 7, when the subbody 2 is pulled in the opposite direction to the arrow in the fully open state, the fixing plate 20 descends downward with respect to the sliding plate 30, and the tension spring 60 is inflated as shown in FIG. 6, and the user continuously pulls the subbody 2 further in the closing direction to change the direction of the pressing force of the tension spring 60, and thus the tension force of the tension spring 60. This causes the free end of the link 40 to return to the first position of the actuation groove 32 as shown in FIG. 5A so that the subbody 3 can be completely closed to the main body 2. FIG. As can be seen in 5b, 6 and 7, the tension soup In the sliding operation of the sliding plate 30 by the 60 and the link 40, the torsion spring 50 is formed by the force between the protrusion 31 of the sliding plate 30 and the guide groove 21 of the fixed plate 20. The balance is to play a secondary role in the smooth sliding of the sliding plate 30. Figure 8 shows a perspective view of another embodiment of the present invention, which is a tension spring used in the embodiment of Figure 3 Except for using the compression spring 160 instead of 60, the operation is the same, so detailed description thereof will be omitted.

As described above, the present invention uses the link and the tension spring (or the compression spring) so that when the subbody is slid on the main body, no sliding noise occurs in the fully open or fully closed position, and the subbody is When sliding in the longitudinal direction of the mobile phone, the tension spring (or compression spring) keeps the free end of the link at a constant elasticity, which enables smooth sliding motion. There is an advantage that the phenomenon in which the subbody flows arbitrarily does not occur.

Although the present invention has been described with reference to the accompanying drawings, the present invention is not limited thereto, and there may be many changes and modifications within the scope of the following utility model registration claims. Fixed to the subbody 2, the sliding plate 30 has been described as being fixed to the main body 3, but this is not intended to limit the present invention, the fixed plate 20 to the main body (3), Of course, the sliding plate 30 may be fixed to the subbody (2).
