Description

Autofolder Type Cell Phone {Autofolder Type Cellular Phone}

The present invention relates to an autofolder-type mobile phone which can automatically open and close a folder. More particularly, the folder is opened and closed at a stable position by controlling the position of the folder to correct the phase difference according to the instability of the driving device and the load. The present invention relates to a folder driving device of a mobile phone.

In general, a mobile phone (Mobile Phone or Cellular Phone) is a terminal that receives a mobile communication service that allows a user to use it within a certain radius within a service area by wirelessly activating a part of a locally fixed subscriber line. While communication is used in a fixed place by line number, a mobile phone can make a call without restriction in place by a logical personal number regardless of 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 (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.

Conventional folder type mobile phone 101 is composed of a main body 102 and a folder 103, the main body 102 usually includes a number (function) button 104 and the microphone 105, therein Various components for handset are built in, and the battery pack 106 for power supply is mounted on one side.

The folder 103 includes a display window 107 for displaying various call information and function information, a speaker 108, and the like, and various components are incorporated therein.

In this folding type cellular phone 101, one end of the folder 103 is supported by the hinge means with respect to the main body 102. The folder 103 is opened or closed by forward or reverse rotation about the hinge means.

However, in the conventional clamshell mobile phone 101 as described above, since the weight of the folder 103 is comparatively heavy, the folder 103 is held by the other hand while the main body 102 is held by one hand to open and close the folder 103. ), There was an inconvenience to open.

In order to improve such a problem, a mobile phone has been proposed to open and close the folder 103 more easily, and a representative thereof is an autofolder type mobile phone using a driving device.

Fig. 2 is a perspective view showing such a conventional autofolder-type cellular phone, and the difference in appearance from the conventional foldable cellular phone is that a switch is provided as a signal applying portion 209 on the outer side of the main body. The most important thing to consider when opening and closing a folder with one hand by operating the signal applying unit 209 as shown in FIG. 2 is to be opened and closed in the manual mode as well as in the automatic mode. It must be designed.

3 is a rotating unit which connects the main body and the folder of the conventional auto folder-type cellular phone, and also includes a power generating means and a power transmission means for automatically opening and closing the folder by a signal by the signal applying unit. It is a perspective view which shows the combination of 211 and the fixing part 210 formed in one side of the main body.

4 is a cross-sectional view showing the rotating part 211 and the fixing part 210, and shows the fixing part 210 formed on both sides of the main body and the rotating part 211 installed in the form of a module housing between the fixing parts. The main part of the mobile telephone in which the drive device for automatic opening and closing of a folder is comprised in the rotating part 211 is shown.

Conventional autofolder-type mobile telephone as shown in Figure 4 and the fixed portion 210 formed on one side of the main body; A rotating part 211 formed in connection with one side of the folder 203 rotatably supported by the fixing part; A motor 212 which is fixed in the rotating unit and is operated in association with a signal applying unit that receives a user's manipulation force as a power generating means for generating a driving force; A reduction gear body 213 connected to an output end of the motor 212 to reduce a rotation ratio and prevent reversal; A first coupler 215 rotatably connected to the reduction gear body; A second coupler 216 slidably installed in the fixing part; It includes an elastic means 217 mounted in the rotating part to apply an elastic force, one side end of the first coupler 215 and one side end of the second coupler 216 is selectively engaged with each other.

Such a conventional auto folder type mobile phone operates the signal applying unit 209 to open the folder 203 in the automatic mode, so that the folder is fixed with the first coupler 215 and the second coupler 216 as fixed points. It rotates for a certain time and stops to open. On the contrary, when the signal applying unit 209 is re-operated to close the folder 203, the motor is driven for a predetermined time in the opposite direction to close the folder, and when used in the manual mode, the first coupler 215 is used. Slip is generated between the second coupler 216 and the folder is opened and closed by elastic force when the folder reaches a predetermined position.

However, in the conventional structure, as shown in FIG. 4, since the elastic means 217 giving elastic force is mounted in the rotating part 211, the length of the rotating part depends on the length of the elastic means 217. That is, there is a problem in that the length of the rotating part 211 should be increased by the length of the spring used as the elastic means.

That is, in the case of the structure in which the motor 212 and the reduction gear body 213 used as the power generating means in the rotating part 211 are sealed as described above, it becomes a great restriction in reducing the outer diameter of the module housing constituting the rotating part 211. have. This is illustrated well through FIG. 4.

In addition, another conventional embodiment has a structure as shown in FIG.

Reference numeral 223 is a ring member.

That is, in another conventional embodiment, when the second coupler 216, which is the power transmission means, is detachably mounted on the fixing part, the force of the elastic means acts on the power generating means and adversely affects the performance of the product. In this case, the elastic means 217 and the second coupler 216, which is the power transmission means, are separated, resulting in a problem that the assembly is deteriorated.

The present invention has been made to solve the above problems, the present invention is to reduce the length and diameter of the rotating part affecting the size of the autofolder-type mobile phone without reducing the elastic force of the elastic means mounted in the fixed portion power It is an object to prevent transmission to the transmission means and the power generating means.

Hereinafter, the first embodiment will be described in detail with reference to the accompanying drawings as a preferred embodiment of the present invention.

The autofolder-type cellular phone as a preferred embodiment according to the present invention has a form similar in appearance to the conventional autofolder-type mobile phone shown in FIG. 2, but the driving device for automatically opening and closing a folder is configured as shown in FIG. This is different from the conventional autofolder type mobile telephone shown in Figs.

That is, the configuration for driving the folder according to the present invention is shown well in the cross-sectional view of the rotating part and the fixing part shown in FIG.

The folder driving apparatus of the mobile phone according to the present invention is largely fixed in the pivoting portion 11 to generate a driving force, a coupler 14 rotatable connected to the power generating means, and the fixing portion 10. ) And a housing 18 provided in the housing, a hinge shaft 15 slidably installed in the housing and receiving a rotational force of the coupler, and one side end selectively engaged with one side end of the hinge shaft. A cam assembly composed of a hinge cam 16 installed in the housing 18 and an elastic means 17 provided in the housing 18 to apply an elastic force to selectively stop and release the hinge cam, and on either side of the main body. And a signal applying unit 9 for applying an operation signal to the power generating means and correspondingly installed at a predetermined position in the coupler and the rotating unit. When this consists of a position sensing means for applying a control signal to the power generating means.

Here, reference numeral 21 denotes a hinge pile.

The power generating means is installed in the cylindrical rotating part 11 formed on one side of the folder 3 and generates a driving force for rotating the folder 3, and the power generating means is usually a motor 12 and a reduction gear body 13. It is composed of

That is, the motor 12 is connected to the signal applying unit 9 provided on one side of the main body 2, and interlocked with the signal applying unit 9, the battery pack (usually mounted on the mobile phone 1) ( It receives power supply from 6) and generates a predetermined rotational force in the forward and reverse directions.

The reduction gear body 13 is configured at the output end of the motor 12, and the reduction gear body 13 is composed of a plurality of planetary gear groups that reduce the rotational force of the motor at a constant ratio, and the planetary gear group has a fixed ratio. By having a reduction ratio, it simultaneously plays the role of a deceleration function and reversal prevention.

Therefore, the power generating means rotates the output stage with the driving force generated in the motor decelerated through the planetary gear group.

Here, the power generating means may be a conventional small motor and a reduction gear body as in the present invention, but having a structural feature that can achieve a reverse reversal at the same time while generating a stable driving force for driving the folder (3) Various types of drive generators may be used.

The power transmission means is composed of a coupler 14, a hinge shaft 15 and a hinge cam 16, as shown in Figure 6 the hinge shaft 15 connected to the coupler 14 is provided on both sides so that the center portion protrudes A taper is formed, and the hinge cam 16 is tapered inwardly so that the central portion is recessed.

The hinge shaft 15 and the hinge cam 16 which are the components of the power transmission means are restrained from each other when the driving force of the power generating means is received by the elastic support force of the elastic means 17. If the folder 3 is manually opened or closed or an external force is applied to the folder during the operation in the automatic mode, the folder 3 is separated from each other.

Such power transmission means is configured such that the coupler 14 and the hinge shaft 15 are rotatably connected to the shaft 22 of the power generating means and the hinge cam 16 is connected to the fixed portion 10, as shown in FIG. The hinge shaft 15 and the hinge cam 16 may be composed of a male coupler and a female coupler, respectively.

As shown in FIG. 6, one end of the elastic means 17 installed in the housing 18 provided in the fixing part 10 of the pair of fixing parts 10 is connected to one side of the housing 18 and the other end thereof. Is connected to one side of the hinge cam 16, which is a power transmission means.

In this way, the elastic means 17 has an elastic support force greater than the driving force generated in the power generating means, the hinge shaft 15 and the hinge cam 16 to form the power transmission means by applying the elastic support force to the power transmission means. To be selectively restrained or unconstrained.

That is, the elastic means 17 is a hinge shaft 15 constituting the power transmission means by applying a greater bearing force to the power transmission means when the folder 3 is opened or closed by the power generating means. And the hinge cam 16 to maintain the state of being bound to each other, and to open and close the folder (3) manually will cause elastic deformation.

The position detecting means controls the power generating means to correct the phase difference by 30 ° with respect to 0 ° and 150 °, which are opening and closing angles of the folder 3.

The position detecting means includes a first position sensor 20 installed at a predetermined position of a power transmission means such as the coupler 14, and a second position sensor 19 installed at a predetermined position corresponding to the first position sensor. When the position sensors on both sides detect a position corresponding to each other, a predetermined control signal is applied to the power generating means.

The present invention discloses a sensor brush and a sensor PCB pattern as the first position sensor 20 and the second position sensor 19 constituting the position sensing means, respectively, in various forms such as hall elements or photosensors, other contact switches, and the like. It is possible to implement.

In addition, the sensor PCB pattern and the sensor brush may be installed in various positions if it can detect the phase between the rotating unit 11 and the power transmission means.

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

First, when the user rotates the folder 3 in the forward or reverse direction to manually open and close the folder 3, the rotating part 11 rotates in the forward or reverse direction in conjunction with the rotation of the folder 3. .

Here, the power transmission means has a greater rotational force applied to the pivoting portion 11 than the elastic support force by the elastic means 17, the hinge shaft 15 and the hinge cam 16 are slipped apart from each other.

As described above, in the case of manually opening and closing the folder 3, the hinge shaft 15 and the housing 18 in the housing 18 that receive the rotational force of the coupler 14 which is rotationally connected to the shaft 22 to the power generating means. Hinge cams 16 connected to one side of the elastic means 17 are spaced apart from each other by slipping, and at the same time the hinge cam 16 is retracted while compressing the elastic means 17 so that the folder 3 can be opened and closed manually. It becomes possible.

In addition, when the user operates the signal applying unit 9 provided on one side of the main body 2 to automatically open the folder 3, the signal applying unit 9 applies a predetermined electric signal to the power generating means. Done.

The power generating means receives a power supply from the battery pack 6 mounted on the mobile phone 1 and generates a predetermined rotational force in a direction for opening the folder 3, the rotational force of the power generating means is a shaft ( It is delivered to the coupler 14 and the hinge shaft 15 connected by 22.

At this time, since the hinge shaft 15 and the hinge cam 16 are rotated at an angle to compress the elastic means 17, the hinge shaft 15 and the hinge cam 16 are moved in a horizontal state by the restoring force of the elastic means 17 when the power generating means is driven. do.

Subsequently, the hinge shaft 15 in the housing receives the rotational force of the power generating means in a state in which the hinge shaft 15 is constrained with the hinge cam 16 in an opposite direction thereof, rather than the driving force of the power generating means. Since the elastic bearing force is large, the hinge shaft 15 and the hinge cam 16 are kept in a restrained state.

Therefore, since the hinge cam 16 is connected in the housing 18, the hinge shaft 15 connected to the hinge cam 16 also becomes a fixed state, so that the outer body of the power generating means rotates.

At this time, the hinge shaft 15 in the housing 18 transmits the rotational movement, but the external force due to the elastic force in the axial direction can reduce the load transmitted to the shaft by blocking the transmission, thereby reducing the elastic force by the elastic means 17. It is expected to improve the reliability and performance by reducing the transmission to the reduction gear 13, which is the power generating means, and to reduce the noise.

Therefore, since the rotating part 11 equipped with the power generating means rotates without being subjected to an axial load, the folder 3 is rotated in one direction and moved to an open position.

At this time, when the second position sensor 19 installed on one side of the same path generating means and the first position sensor 20 installed on one end of the coupler 14 reach the predetermined position in the pivoting part 11, a predetermined electrical signal is reached. Is applied to the power generating means and the driving is stopped to complete the opening of the folder 3.

In addition, when the user operates the signal applying unit 9 provided on one side of the main body 2 to automatically close the folder 3, the electric signal generated by the signal applying unit 9 is applied to the power generating means. .

At this time, the power generating means receives a power supply from the battery pack 6 mounted on the mobile phone 1 and generates a predetermined rotational force in a direction to close the folder (3), the rotational force of the power generating means is output stage It is delivered to the hinge shaft 15 connected to.

Here, the hinge shaft 15 is maintained in a state in which the hinge cam 16 and the elastic means 17 are mutually bound in the housing 18.

Therefore, since the power transmission means is bound and has a fixed state, the outer body constituting the power generating means rotates.

Therefore, the folder 3 having the rotating part 11 on which the power generating means is mounted is rotated in the reverse direction so that the folder 3 is closed.

Here, when the folder 3 reaches the shielded position, the folder 3 is no longer rotated by the contact with the main body 2, so that the load acts on the power generating means.

At this time, since the load acting on the folder 3 is greater than the elastic bearing force of the elastic means 17, the hinge shaft 15 and the hinge cam 16 are slipped and spaced apart from each other. 17 is compressed.

Therefore, the hinge shaft 15 is rotated by the driving force of the power generating means, and at this time, the first position sensor 20 installed at one end of the coupler 14 connected to the hinge shaft 15 and the turn opposite thereto. When the second position sensor 19 installed at one end of the reduction gear body 13, which is the power generating means in the eastern portion 11, becomes in phase, the stop signal is applied to the power generating means, so that the shielding of the folder 3 is completed.

When the folder 3 is subjected to a load during the operation of opening the folder 3 in the automatic mode, the folder 3 is fixed and the hinge shaft 15 overcomes the elastic bearing force of the elastic means 17 and the hinge cam 16. ) And rotated in a slipped state.

Therefore, when the first position sensor 20 of the coupler 14 is in phase with the second position sensor 19 installed in the pivoting portion 11, the power generating means is stopped, and the hinge shaft 15 and the folder ( The position of 3) has the same position as the manual mode.

Therefore, by the restoring force of the elastic means 17, the folder 3 is moved to the closest position among the positions of the opening and the shielding to complete the opening and closing.

Meanwhile, even when a load is applied to the folder 3 during the operation of closing the folder 3 in the automatic mode, the folder 3 is opened and closed in the same manner as the above-described example.

Figure 7 shows a second embodiment of the present invention, as shown in the auto-folder-type mobile phone with a fixed portion formed on one side of the main body; A rotating part formed at one side of the folder rotatably supported by the fixing part; Power generating means fixed in the rotating part to generate a driving force; A coupler rotatably connected to the power generating means; A housing provided in the fixing part; A hinge cam slidably installed in the housing and having a hinge cam to receive the rotational force of the coupler, and a side end selectively engaged with one side end of the hinge cam, the hinge shaft installed in the housing, and provided in the housing to provide the hinge shaft. A cam assembly composed of elastic means for selectively acting on an elastic force to stop and release rotation; A signal applying unit provided on one side of the main body to apply an operation signal to the power generating means; And a position sensing means for applying a control signal to the power generating means when the hinge shaft and the pivoting portion are installed in correspondence with each other at a predetermined position.

Since the power generating means is the same as the configuration and operation of the first embodiment of the present invention described above, description thereof will be omitted.

The power transmission means is composed of a coupler 14, a hinge cam 16 and a hinge shaft 15, as shown in Figure 7, the hinge cam 16 connected to the coupler 14, the inner side is recessed Taper is formed, and the hinge shaft 15 is tapered on both sides so that the central portion protrudes.

The hinge cam 16 and the hinge shaft 15, which are components of the power transmission means, are restrained from each other when the driving force of the power generating means is received by the elastic support force of the elastic means 17. If the folder 3 is manually opened or closed or an external force is applied to the folder during the operation in the automatic mode, the folder 3 is separated from each other.

Such a power transmission means is a coupler 14 is connected to the shaft 22 of the power generating means, the hinge cam 16 is connected to the coupler as shown in Figure 7 and the hinge shaft 15 to the fixing portion 10 The hinge cam 16 and the hinge shaft 15 may be configured as a female coupler and a male coupler, respectively.

As shown in FIG. 7, one end of the elastic means 17 installed in the housing 18 provided in the fixing part 10 of one of the pair of fixing parts 10 is connected to one side of the housing, and the other end is power transmission. It is connected to one side of the hinge shaft 15 as a means.

In this way, the elastic means 17 has an elastic support force greater than the driving force generated in the power generating means, the hinge cam 16 and the hinge shaft 15 forming the power transmission means by acting on the power transmission means. May be selectively constrained or unconstrained.

In other words, the elastic means 17 has a hinge cam 16 constituting the power transmission means by applying a greater bearing force to the power transmission means when the folder 3 is opened or closed by the power generating means. The hinge shaft 15 and the hinge shaft 15 are held together, and when the folder 3 is opened and closed manually, elastic deformation occurs.

Since the position detecting means is the same as the configuration and operation of the first embodiment of the present invention described above, description thereof will be omitted.

The folder driving apparatus of the cellular phone according to the second embodiment of the present invention made as described above is as follows.

First, when the user rotates the folder 3 in the forward or reverse direction to manually open and close the folder 3, the rotating part 11 rotates in the forward or reverse direction in conjunction with the rotation of the folder 3. .

Here, the power transmission means has a greater rotational force applied to the rotating part 11 than the elastic support force by the elastic means 17, so that the hinge cam 16 and the hinge shaft 15 are slipped and spaced apart from each other.

As described above, in the case of manually opening and closing the folder 3, the coupler 14 rotatably connected to the shaft 22 with the power generating means, the hinge cam 16 in the housing connected thereto, and the elastic means 17 at one side of the housing. The hinge shafts 15 connected to each other are slipped and spaced apart from each other, and at the same time, the hinge shafts 15 retreat while compressing the elastic means 17 so that the folder 3 can be opened and closed manually.

In addition, when the user operates the signal applying unit 9 provided on one side of the main body 2 to automatically open the folder 3, the signal applying unit 9 applies a predetermined electric signal to the power generating means. Done.

The power generating means receives a power supply from the battery pack 6 mounted on the mobile phone 1 and generates a predetermined rotational force in a direction for opening the folder 3, the rotational force of the power generating means is a shaft ( It is transmitted to the coupler 14 and the hinge cam 16 connected by 22.

At this time, since the hinge cam 16 and the hinge shaft 15 are rotated by a predetermined angle to compress the elastic means 17, the hinge cam 16 and the hinge shaft 15 are moved in a horizontal state by the restoring force of the elastic means 17 when the power generating means is driven. do.

Subsequently, the hinge cam 16 in the housing receives the rotational force of the power generating means in a state in which the hinge cam 16 is constrained with the hinge shaft 15 in the opposite direction, rather than the driving force of the power generating means. Since the elastic bearing force is large, the hinge cam 16 and the hinge shaft 15 are kept in a restrained state.

Therefore, since the hinge shaft 15 is connected to the housing 18, the hinge cam 16 connected to the hinge shaft 15 also becomes a fixed state, so that the outer body of the power generating means rotates.

At this time, the hinge cam 16 in the housing 18 transmits the rotational movement, but the external force due to the elastic force in the axial direction can reduce the load transmitted to the shaft by blocking the transmission, thereby reducing the elastic force by the elastic means 17. By not being transmitted to the reduction gear body 13 which is the power generating means, reliability and performance improvement are expected, and noise reduction is expected.

Therefore, since the rotating part 11 equipped with the power generating means rotates without being subjected to an axial load, the folder 3 is rotated in one direction and moved to an open position.

At this time, when the second position sensor 19 installed at one side of the power generating means and the first position sensor 20 installed at one end of the coupler 14 reach the predetermined position in the pivoting part 11, a predetermined electrical signal is reached. Is applied to the power generating means and the driving is stopped to complete the opening of the folder 3.

In addition, when the user operates the signal applying unit 9 provided on one side of the main body 2 to automatically close the folder 3, the electric signal generated by the signal applying unit 9 is applied to the power generating means. .

At this time, the power generating means receives a power supply from the battery pack 6 mounted on the mobile phone 1 and generates a predetermined rotational force in a direction to close the folder (3), the rotational force of the power generating means is output stage It is delivered to the hinge cam 16 connected to.

Here, the hinge cam 16 is maintained in a state in which the hinge shaft 16 and the hinge shaft 15 and the elastic means 17 are mutually bound in the housing.

Therefore, since the power transmission means is bound and has a fixed state, the outer body constituting the power generating means rotates.

Therefore, the folder 3 having the rotating part 11 on which the power generating means is mounted is rotated in the reverse direction so that the folder 3 is closed.

Here, when the folder 3 reaches the shielded position, the folder 3 is no longer rotated by the contact with the main body 2, so that the load acts on the power generating means.

At this time, the load acting on the folder (2) is greater than the elastic bearing force of the elastic means 17, so the hinge cam 16 and the hinge shaft 15 are slipped and spaced apart from each other, and at the same time, the power generating means retreats and the elastic means 17 is compressed.

Accordingly, the hinge cam 16 is rotated by the driving force of the power generating means, and at this time, the first position sensor 20 installed at one end of the hinge cam 16 and the power in the rotating part 11 opposite thereto. When the second position sensor 19 installed at one end of the reduction gear body 13, which is the generating means, is in phase, the stop signal is applied to the power generating means, so that the shielding of the folder 3 is completed.

If the folder 3 is subjected to a load during the operation of opening the folder 3 in the automatic mode, the folder 3 is fixed and the hinge cam 16 overcomes the elastic bearing force of the elastic means 17 and the hinge shaft 15 ) And rotated in a slipped state.

Therefore, when the first position sensor 20 of the coupler 14 is in phase with the second position sensor 19 installed on the power transmission means in the pivoting portion 11, the power generating means is stopped and the hinge cam 16 ) And the folder 3 have the same position as the manual mode.

Therefore, by the restoring force of the elastic means 17, the folder 3 is moved to the closest position among the positions of the opening and the shielding to complete the opening and closing.

Meanwhile, even when a load is applied to the folder 3 during the operation of closing the folder 3 in the automatic mode, the folder 3 is opened and closed in the same manner as the above-described example.

8 is a view showing a third embodiment of the present invention, unlike the above-described embodiments, the hinge shaft 15 and the hinge cam 16 are directly connected to the power generating means without the coupler by the shaft 22. It is.

That is, the autofolder-type mobile telephone according to the third embodiment of the present invention includes a fixing part formed at one side of the main body; A rotating part formed at one side of the folder rotatably supported by the fixing part; Power generating means fixed in the rotating part to generate a driving force; A housing provided in the fixing part; A hinge shaft rotatably installed in the housing and connected to the power generating means and rotatable; A cam assembly comprising a hinge cam provided in one side of the hinge shaft and one side end selectively engaged with the hinge shaft, and an elastic means provided in the housing and elastic means for selectively rotating rotation and releasing the hinge cam; ; A signal applying unit provided on one side of the main body to apply an operation signal to the power generating means; And a position sensing means for applying a control signal to the power generating means when the hinge shaft and the pivot shaft are installed in correspondence with each other at a predetermined position.

The power generating means is installed in the cylindrical rotating part 11 formed at one side of the folder 3 and generates a driving force for rotating the folder 3, and the configuration and operation of the power generating means are the same as in the above-described embodiment. So I want to skip the explanation.

The power transmission means is composed of a hinge shaft 15 and the hinge cam 16, as shown in Figure 8 the hinge shaft 15 connected to the power generating means is tapered on both sides so that the central portion protrudes, the The hinge cam 16 is tapered inwardly so that the center part is recessed.

The hinge shaft 15 and the hinge cam 16, which are components of the power transmission means, are restrained and fixed to each other when the driving force of the power generating means is received by the elastic support force of the elastic means 17 to be described later. The point is formed, and when the folder 3 is opened or closed manually or an external force is applied to the folder during the operation in the automatic mode, the structure is separated from each other.

Such power transmission means may be configured such that the hinge shaft 15 is rotatably connected to the shaft 22 of the power generating means and the hinge cam 16 is connected to the fixed portion 10 as shown in FIG. 8. The hinge shaft 15 and the hinge cam 16 may be constituted by a male coupler and a female coupler, respectively.

As shown in FIG. 8, one end of the elastic means 17 installed in the housing provided in the fixing part 10 of one pair of the fixing parts 10 is connected to one side of the housing 18, and the other end is power transmission. It is connected to one side of the hinge cam 16 as a means.

In this way, the elastic means 17 has an elastic support force greater than the driving force generated in the power generating means, the hinge shaft 15 and the hinge cam 16 to form the power transmission means by applying the elastic support force to the power transmission means. To be selectively restrained or unconstrained.

That is, the elastic means 17 is a hinge shaft 15 constituting the power transmission means by applying a greater bearing force to the power transmission means when the folder 3 is opened or closed by the power generating means. And the hinge cam 16 to maintain the state of being bound to each other, and to open and close the folder (3) manually will cause elastic deformation.

The position detecting means controls the power generating means to correct the phase difference by 30 ° with respect to 0 ° and 150 °, which are opening and closing angles of the folder 3.

The position detecting means includes a first position sensor 20 installed at a predetermined position of a power transmission means such as the hinge shaft 15, and a second position sensor installed at a predetermined position corresponding to the first position sensor ( 19), and when the position sensors on both sides detect the positions corresponding to each other, a predetermined control signal is applied to the power generating means.

Since the configuration 19 and the operation of the first position sensor 20 and the second position sensor according to the third embodiment of the present invention are the same as in the above-described embodiment, description thereof will be omitted.

The case of the folder driving apparatus of the cellular phone according to the third embodiment of the present invention made as described above is as follows.

First, when the user rotates the folder 3 in the forward or reverse direction to manually open and close the folder 3, the rotating part 11 rotates in the forward or reverse direction in conjunction with the rotation of the folder 3. .

Here, the power transmission means has a greater rotational force applied to the pivoting portion 11 than the elastic support force by the elastic means 17, the hinge shaft 15 and the hinge cam 16 are slipped apart from each other.

As described above, when the folder 3 is opened and closed manually, the hinge cam 16 connected to the hinge shaft 15 in the housing rotatably connected to the power generating means by the shaft 22 and the elastic means 17 on one side of the housing. The slips are spaced apart from each other, and at the same time the hinge cam 16 is retracted while compressing the elastic means 17 so that the folder 3 can be opened and closed manually.

In addition, when the user operates the signal applying unit 9 provided on one side of the main body 2 to automatically open the folder 3, the signal applying unit 9 applies a predetermined electric signal to the power generating means. Done.

The rotational force by the power generating means is transmitted to the hinge shaft 15 connected to the shaft 22.

At this time, since the hinge shaft 15 and the hinge cam 16 are rotated at an angle to compress the elastic means 17, the hinge shaft 15 and the hinge cam 16 are moved in a horizontal state by the restoring force of the elastic means 17 when the power generating means is driven. do.

Subsequently, the hinge shaft 15 in the housing 18 receives the rotational force of the power generating means in a state in which the hinge shaft 15 is constrained with the hinge cam 16 in the opposite direction thereof, and is more elastic than the driving force of the power generating means. Since the elastic bearing force of 17) is large, the hinge shaft 15 and the hinge cam 16 remain in a restrained state.

Therefore, since the hinge cam 16 is connected in the housing 18, the hinge shaft 15 connected to the hinge cam 16 also becomes a fixed state, so that the outer body of the power generating means rotates.

At this time, the hinge shaft 15 in the housing transmits rotational movement, but external force caused by the elastic force in the axial direction can reduce the load transmitted to the shaft by blocking transmission, so that the elastic force by the elastic means is a power generating means. By not being transmitted to the body 13 is expected to improve the reliability and performance and noise reduction is expected as the other embodiments of the present invention described above.

The rest of the operation will be omitted because it is the same principle as in the above-described first and second embodiments.

9 illustrates a case in which the positions of the hinge shaft 15 and the hinge cam 16 are changed from each other, that is, the male and female shapes are different from each other in the third embodiment. As shown in Fig. 9, since the fourth embodiment of the present invention has the same operation and principle as the third embodiment, the description thereof will be omitted.

That is, the above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and the scope of application of the present invention is not limited thereto, and may be appropriately changed within the scope of the same idea. For example, the shape and structure of each component shown in the embodiment of the present invention can be modified.

In addition, although the present invention described above has been shown as an embodiment of a foldable mobile phone, the present invention is not necessarily limited to a foldable mobile phone, but 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.

Through the embodiments of the present invention, it is possible to miniaturize the size of the autofolder type mobile telephone without increasing the length and diameter of the rotating part, and to prevent the elastic force of the elastic means mounted in the fixing part from being transmitted to the power transmitting means and the power generating means. As a result, product reliability and noise reduction and performance improvement are expected.
