Description

Operating system of cellular phone's folder

The present invention relates to a mobile phone capable of opening and closing a folder as well as automatic and manual. More particularly, the folder is stabilized from the main body by compensating the phase difference due to the unstable characteristics of the driving device and the phase difference due to the mixed use of automatic and manual. It relates to a folder driving device of the mobile phone to be opened and closed.

In general, a cellular phone (Cellular Phone / Personal Communication Services) is a terminal that receives a mobile communication service to enable the use within a certain radius within the service area by radioizing a part of the locally fixed subscriber line. Whereas the communication is used in a fixed place by the line number, the mobile phone can make a call regardless of the place by the logical personal number regardless of the line.

Such a mobile phone is explosive in demand due to its ease of portability and convenience in use, and is becoming a miniaturized and multifunctional device in order to meet various needs of consumers.

In general, a mobile phone has a bar type in which the number (function) button is exposed to the outside according to its shape, a flip type having a cover shielding the number (function) button with a cover, and a main body. It is classified into a folder type that is folded in half, and according to the trend of miniaturization, the spread of folder type mobile phones is increasing.

1 is a perspective view showing a general folding type cellular phone according to the prior art.

As shown in FIG. 1, a conventional autofolder-type mobile phone is composed of a main body 110 and a folder 120, and the main body 110 is usually provided with a number (function) button and a microphone, and has a song inside. Various components for hydration are built in, and a battery pack (B) for power supply is mounted on one side.

The folder 120 includes a display window for displaying various call information and function information, a speaker, and the like, as well as various components.

The auto folder 120 of this type of mobile phone 100 is supported by the hinge means, one end of the folder 120 with respect to the main body 110, and the opening and closing by rotating in the forward or reverse direction about the hinge means. Is achieved.

However, since the conventional autofolder type 120 mobile phone 100 as described above has a relatively heavy weight of the folder 120, in order to open and close the folder 120, the folder 110 is held with one hand while the main body 110 is held with one hand. There was an inconvenience to open 120.

In order to improve such a problem, a mobile phone 100 has been recently proposed to open and close the folder 120 more easily, and a representative one of them is to use a driving device.

That is, by operating the switch (S) with one hand to drive the drive device so that the folder 120 can be automatically opened and closed, the most important consideration here is to be able to use a mixture of automatic and manual.

2 is a cross-sectional view showing the configuration of a driving apparatus in the auto clamshell cellular phone according to the prior art, and FIG. 3 is a cross-sectional view showing an operating state of FIG.

As shown, the drive device 130 includes a motor 131 receiving elastic support of the coil spring 133 on one side, and a gear box 132 configured on the output end side of the motor 131.

The motor 131 is operated in conjunction with a switch S receiving a user's manipulation force, and generates a predetermined driving force only for a time set by a timer built in the mobile phone 100.

The gear box 132 is connected to the output terminal of the motor 131 to reduce the rotation ratio and at the same time to prevent reversal, the male coupler 135 is coupled to the output end side, the male coupler 135 is the main body 110 It is selectively engaged with the female coupler 115 formed in the shaft of the high.

Such a conventional mobile phone has a male coupler 135 and a female coupler 115 engaged with each other when the switch S is operated in order to automatically open the folder 120. Therefore, the mobile phone has a fixed point. The outer body rotates.

Therefore, the folder 120 having the cylindrical housing 121 in which the motor 131 is installed also rotates for a predetermined time to achieve an open state from the main body 110.

On the contrary, when the switch S is re-operated to close the folder 120, the outer body of the motor 131 is rotated in the reverse direction using the male coupler 135 as a fixed point so that the folder 120 is also rotated in the reverse direction and closed. Is achieved.

Meanwhile, when the folder 120 is rotated in one direction or the reverse direction from the main body 110 in order to manually open or close the folder 120, a slip is generated between the male coupler 135 and the female coupler 115. ) Compresses the coil spring 133 integrally with the motor 131 to cause a displacement, and the folder 120 is rotated.

When the folder 120 reaches a predetermined position, the male coupler 135 is returned to its original position by the elastic bearing force of the coil spring 133, and the folder 120 is opened rapidly by re-joining with the female coupler 115. It is closed.

However, in the conventional folder 120 type mobile phone 100 as described above, since the motor 131 for rotating the folder 120 is operated by a timer for a predetermined time, the output characteristic of the motor 131, that is, RPM is changed. There is a problem such that the folder 120 is stopped without reaching the set position (open position / close position) for complete opening and closing.

In addition, since the operation angle of the folder 120 is 150 ° while the operation angle of the male coupler 135 is 180 °, a great problem does not occur during automatic operation or manual operation. When opening and closing the phase difference of 30 ° is generated, there is a problem that the opening and closing of the folder 120 is incomplete.

Then, when the folder 120 is automatically opened and closed by the hand holding the folder 120 or the switch (S) is incorrectly operated in the state stored in the pocket or the like and the external force acts on the folder 120, the male at a specific position As the coupler 135 is stopped, the folder 120 is not completely closed in the manual mode, or the folder 120 is opened at an opening angle of 150 ° or more.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a folder driving apparatus of a mobile phone that can achieve a stable opening and closing of the folder by compensating the phase difference between the folder and the male coupler. .

The cellular phone 1 is composed of a main body 10 provided with operation buttons and a microphone for handset, and a folder 20 provided with a display window and a speaker for displaying various kinds of information.

The main body 10 has a pair of shaft fixing portion 11 protrudes on one side, the pair of shaft fixing portion 11 forms a fixing groove 12 in a direction facing each other.

In addition, the folder 20 has a cylindrical housing 21 having both sides open on one side thereof, and the housing 21 is disposed between the pair of shaft fixing portions 11.

In addition, a drive motor 30 for generating a driving force for automatically opening and shielding the folder 20 is installed in the housing 21, and the drive motor 30 is a switch provided at one side of the main body 10. In conjunction with S), the rotational force in the forward and reverse directions is generated during the set time of the timer built in the cellular phone 1.

The drive motor 30 includes a gearbox (not shown) for a deceleration purpose, and is operated by receiving a power supply from the battery pack B mounted on the mobile phone 1.

Such a structure is substantially the same as the structure of the conventional cellular phone 1. However, the folder driving apparatus of the mobile phone according to the present invention is configured on both sides of the driving motor 30, respectively, to fix the output terminal of the driving motor 30 in the automatic mode and to release the restraining force on the output terminal in the manual mode. A first coupler 40 and a second coupler 50 for releasing the restraining force on the other output end of the drive motor 30 in the automatic mode and fixing the other output end in the manual mode.

The first coupler 40 is configured between an output end of one side of the drive motor 30 and the shaft fixing unit 11 of the main body 10 in a position opposite to the output end, and generates a predetermined fixing force through interaction. Or a first rotor 41 and a first stator 45 to be slid or slipped.

Here, the first rotor 41 has a disc shape and is located in the housing 21, and one side output end of the driving motor 30 is axially coupled to the central portion thereof to be integrally interlocked.

The first rotor 41 has a ring-shaped guide groove 42 having a predetermined depth in the circumferential direction on one side, that is, on a surface facing the first stator 45 to be described later.

The first stator 45 is installed in the fixing groove 12 of the shaft fixing part 11 in a direction opposite to the first rotor 41, and the elastic member 2 installed in the fixing groove 12. Connected and exert elastic support.

The first stator 45 has a plurality of protrusions 46 formed in the circumferential direction on the other side, that is, on the surface opposite to the above-described first rotor 41, and the protrusions include the first rotor 41. It is inserted into the guide groove 42 of.

Here, the elastic support force of the elastic member 2 for contacting the first rotor 41 and the first stator 45 in a rigid state is configured to be set larger than the rotation torque of the drive motor 30.

Therefore, when the driving motor 30 rotates, the first rotor 41 and the first stator 45 maintain a stable coupling state so that the outer body of the driving motor 30 is rotated.

The second coupler 50 is configured between the other output terminal of the drive motor 30 and the shaft fixing unit 11 of the main body 10 in a position opposed to the other output terminal, and through the interaction to the predetermined fixing force And a second rotor 51 and a second stator 55 which are generated or slid.

Here, the second rotor 51 is made of a disc shape and is located in the housing 21, the other output end of the drive motor 30 is axially coupled to the central portion thereof to be interlocked integrally.

The second rotor 51 has a pair of protrusions 52 formed in one circumferential direction on one side thereof, that is, on a surface facing the second stator 55 to be described later, and the pair of protrusions 52 are usually It is preferable to form at intervals of 180 degrees.

The second stator 55 is installed in the fixing groove 12 of the shaft fixing unit 11 in a direction opposite to the second rotor 51, and the elastic member 3 installed in the fixing groove 12. ), You receive elastic support.

The second stator 55 is a pair of guide grooves for guiding the projections 52 of the second rotor 51 in the circumferential direction on the other side, that is, the surface facing the second rotor 51 described above. 56 is formed.

The pair of guide grooves 56 have a semi-circular arc shape with a predetermined interval therebetween, and are formed to have a lower depth while proceeding from both ends to the center portion.

Meanwhile, in the second coupler 50 having the above configuration, a pair of protrusions 52 formed on the second rotor 51 are inserted into a pair of guide grooves 56 formed on the second stator 55.

In addition, the elastic support force of the elastic member 3 for contacting the second rotor 51 and the second stator 55 in a firm state is configured to be set smaller than the rotation torque of the driving motor 30.

Therefore, when the driving motor 30 is rotated, the second rotor 51 and the second stator 55 are mutually slipped to perform a sliding motion, and in particular, the protrusion 52 of the second rotor 51 is inserted. The second stator 55 overcomes the bearing force of the elastic member 3 by the height difference of the pair of guide grooves 56 and retreats.

Therefore, the present invention made as described above is the phase difference by fixing the second rotor 51 of the second coupler 50, which is a portion for detecting the position of the drive motor 30 and the drive motor 30 to rotate integrally Will be removed.

Referring to the folder driving apparatus of the mobile phone according to the present invention made as described above is as follows.

When the user operates the switch S provided on one side of the main body 10 to automatically open the folder 20, the switch S applies a predetermined electric signal to the driving motor 30.

Subsequently, the driving motor 30 receives a power supply from the battery pack B mounted on the mobile phone 1 and generates a predetermined rotational force in a direction for opening the folder 20. Although not shown, the rotational force of 30 is transmitted to the first coupler 40 connected to the output end in a decelerated state through a gearbox.

Here, the drive motor 30 may be driven for about 10 to 20% longer than the previous drive time, thereby causing a problem due to an output characteristic of the drive motor 30, that is, a change in RPM.

On the other hand, since the support force of the elastic member 2 for supporting the first rotor 41 and the first stator 45 is greater than the rotational torque of the driving motor 30, the first coupler 40 is elastically restrained from each other. Will remain intact.

Accordingly, since the first coupler 40 cannot rotate and the outer body constituting the drive motor 30 rotates, the folder 20 having the housing 21 on which the drive motor 30 is mounted is the main body 10. ) Is rotated to achieve opening.

In addition, when the user automatically closes the folder 20, an operation signal is applied to the driving motor 30 by operating a switch S provided at one side of the main body 10.

Then, the driving motor 30 receives a power supply from the battery pack B and generates a predetermined rotational force in a direction for shielding the folder 20, and the rotational force of the driving motor 30 is reduced through a deceleration means. It is transmitted to the first coupler 40 coupled to the output terminal in a decelerated state at a constant rate.

On the other hand, since the first coupler 40 automatically maintains a mutually constrained state as in the case where the folder 20 is automatically opened, the outer body of the driving motor 30 rotates around the first coupler 40. .

Therefore, the folder 20 having the housing 21 on which the drive motor 30 is mounted is moved to the main body 10 to achieve shielding.

Here, when the folder 20 is opened and closed in the automatic mode as described above, the second coupler 50 drives the support force of the elastic member 3 supporting the second stator 55 and the second rotor 51. Since the torque is smaller than the rotational torque of the motor 30 is mutually sliding movement.

Therefore, as the second rotor 51 rotates, the protrusions 52 of the second rotor 51 travel along the pair of guide grooves 56 having the height difference, and thus, the second stator 55. Overcomes the bearing force of the elastic member 3 and retracts.

At this time, since the projection 52 of the second rotor 51 is advanced to both ends of the guide groove 56 by the shape of the pair of guide grooves 56 formed in the second stator 55 is applied Shaking is compensated for when the folder 20 is fully opened and closed.

In addition, if the user rotates the folder 20 in the forward or reverse direction to manually open and close the folder 20, the housing 21 rotates in the forward or reverse direction by the rotation of the folder 20, the housing The drive motor 30 installed in the 21 is also rotated integrally.

In this case, the first coupler 40 connected to one output end of the driving motor 30 has a first rotor 41 and a first stator because an acting force acting on the folder 20 is greater than a supporting force of the elastic member 2. The restraining force is released by slipping 45).

In addition, since the protrusions 52 of the second rotor 51 move along the guide grooves 56 of the second stator 55, the second coupler 50 connected to the other output terminal of the driving motor 30 is moved. The folder 20 can be opened and closed manually.

In particular, the protrusion 52 of the second rotor 51 has a strong restoring force to be advanced to both ends by the shape of the guide groove 56 formed deeper than the center portion of both ends, so the opening and closing of the folder 20 is performed. Is done quickly.

On the other hand, when the folder 20 is opened or closed in the automatic mode, when an external force is applied to the folder 20 so as not to be opened or closed, the first coupler 40 is slipped by the above-described configuration and the second coupler 50 is closed. Becomes the operating state of the manual mode.

Therefore, the second coupler 50 moves the folder 20 to the closest position among the open or shielded positions by the above-described configuration to complete the opening and closing.

The folder driving device of the mobile phone according to the present invention configured and operated as described above can eliminate the phase difference generated when opening and closing the folder by using a mixture of automatic and manual, thereby improving the reliability of the operation.

In addition, the folder driving apparatus of the mobile phone according to the present invention automatically transfers the folder to the initial position or the open position even when an external force is applied to the folder in an operation of automatically opening and shielding the folder, thereby ensuring continuity of operation. There is an advantage.

Therefore, the present invention can not only open and close the folder as well as automatic and manual, but also can correct the phase difference of the folder generated when the automatic and manual are mixed, and can achieve a functional improvement of the mobile phone with a simple component configuration. There is an advantage.

In addition, although the present invention described above has been described as a folding type mobile phone by way of example, the present invention is not necessarily limited to a folding type mobile phone, and a mobile communication device having a cover (flip) which is hinged to be rotatable in a main body. And various types of portable electronic products.
