Description

{Automatic driving type slide phone, automatic driving method for a slide phone, and detecting method for incoming call for mobile phone}

The present invention detects an incoming signal using an automatic drive type slide phone that implements the opening and closing operation by automatically driving the slide-type mobile phone, an automatic driving method for implementing the opening and closing operation of the slide phone, and the opening and closing operation of the slide phone It is about how to.

Recently, the demand for the mobile communication terminal has increased due to the convenience of use, and the trend is miniaturization and multifunction in order to satisfy various needs of consumers. In general, a mobile communication terminal has a bar type in which numbers and function buttons are exposed to the outside without a separate additional case according to its shape, and a flip having a second case separately attached to a case constituting the main body. flip type and folder type. Recently, in accordance with the trend of miniaturization of terminals, the spread of folder type mobile phones has been increasing.

Recently, as the functions of the mobile phone are developed, the functions are not limited to calls, but are expanding the range of use such as receiving e-mail, watching videos, and cameras. In addition, in order to implement various functions as described above, LCDs are becoming larger and larger, and the overall size and weight of mobile phones are gradually decreasing to increase portability.

In order to satisfy this need, a folding type cellular phone or a slide type mobile phone (hereinafter, referred to as a 'slide phone') is widely used. In the case of a clamshell phone or a slide phone, it can be configured to show a large LCD when it is in an open state, and it can usually be carried in a small size.

1 is a perspective view showing an opening and closing operation of a conventional slide phone. The conventional slide phone 1 includes a first case 2 and a second case 3, and the first case 2 performs an opening operation while being moved downward with respect to the second case 3. Done. When the slide phone 1 is opened, the user can see the LCD screen 4 mounted on the second case 3.

In the case of the conventional slide phone as shown in FIG. 1, the user manually moves the first case downward or upward to perform the opening or closing operation, thereby making it inconvenient for the user to use the slide phone. Accordingly, a conventional slide phone that automatically implements the opening and closing operations of such a slide phone is shown in FIG. 2.

2 is a cross-sectional view of a conventional automatic driving drawer type mobile telephone. The drawer-type mobile telephone of FIG. 2 includes a pinion gear 30 mounted at one end of the main body 10 and a rack gear mounted longitudinally at one side of the drawer cover 20 and engaged with the pinion gear 30. 32, a drive motor 40 mounted on the main body 10 to provide a driving force, a worm gear device 42 for transmitting the driving force of the drive motor 40 to the pinion gear 30, and the drive motor 40 ) Consists of a control switch that controls the operation of

When the driving motor 40 is operated by the user operating the control switch in the state in which the drawer cover 20 is closed, the mobile phone has a rotational force of the pinion gear 30 through the worm gear device 42. The pinion gear is rotated, and the rack gear 32 engaged with the pinion gear moves so that the drawer cover 20 moves upward to perform the opening operation. At this time, the drive motor 40 is configured to automatically stop after a predetermined time or a predetermined number of times after the rotation operation is started, thereby preventing the drawer cover 20 from being separated from the main body 10.

However, in the case of the slide type mobile phone having such a structure, the controller is configured to perform the operation of stopping or driving the rotation of the drive motor by a predetermined time or a predetermined number of times. If a defect occurs, the drawer cover, which is a different case from the main body, may not be opened and closed correctly.

In addition, when an external force is applied from the outside to prevent the cover from being completely opened, the power is continuously supplied to the motor, causing the battery to be quickly consumed, and causing a problem caused by an overload in the driving system. In addition, the above structure is limited to the functions that can be implemented to perform only the fully open or fully closed operation is inconvenient in use.

Apart from the above problem, when receiving a call through a mobile communication terminal, the user typically uses three types of visual, tactile, auditory, olfactory, and taste to recognize the incoming call. That is, the reception is sensed using three kinds of ringtones (hearing), vibration (tactile), and light (visual), and the user can select between hearing, tactile, and visual.

In particular, in order to detect reception through vibration, a vibration motor should be used, and the vibration motor rotates a rotor manufactured in an eccentric shape so that a user can recognize a call signal through vibration caused by eccentric rotation generated at this time. . The detection method except the detection through the ring or LED light is not used separately except for using the vibration motor.

However, in the conventional signal detection method, the vibration detection method has a problem that the position where the vibration motor used for the detection of the signal by the vibration is increasingly narrowed by various other composite parts, vibration motor And other composite parts limit the size of the mobile phone.

Therefore, a new method is being researched to allow a user to detect a call signal reception without using a vibration motor. If a signal can be detected as in the prior art without using a vibration motor, the size of a mobile phone can be reduced, and the cost of installing a vibration motor can be reduced, and a mobile phone assembly process can be simplified. You will get a number of advantages.

Therefore, the study of the new signal detection method using the automatic drive system of the slide phone provided by the present invention without using a vibration motor has been continued in the art.

The present invention is to solve the above problems, it is an object of the present invention to automatically open and close the function, and to provide a structure and driving method of the automatic drive type slide phone to perform the correct opening and closing operation.

In addition, the present invention is to automatically return when the external force is applied during the opening and closing operation, or when the user starts the manual operation of the auto-driven slide phone that can automatically complete the opening and closing operation It is an object to provide a structure and a driving method.

In addition, instead of detecting the signal using the vibration motor to detect the incoming call through the movement of the case of the slide phone to improve the reception recognition rate, and to reduce the size and cost of the mobile communication terminal.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Figure 3 is a side cross-sectional view of the self-driven slide phone according to the present invention, Figure 4 is a front view of the self-driven slide phone according to the present invention.

The slide phone according to the present invention includes a first case 100 and a second case 200 in which various portable communication components are mounted. When the slide phone is operated, the first case 100 slides up and down with respect to the second case 200.

5 is a view showing a sensor attachment structure of the self-driven slide phone according to the present invention. The present invention provides a structure of a slide phone for automatically performing the opening and closing operation of the slide phone, to use a method of driving the drive motor for the automatic driving of the slide phone. At this time, it is necessary to accurately drive the drive motor to the open and closed positions. To this end, the present invention uses the same sensing means as in FIG.

In FIG. 5, the first case 100 is equipped with a target for position detection 170. In addition, the second case 100 is provided with at least two detection means (150, 160) for detecting the position detection target 170. The position detecting target 170 is detected by the sensing means 150 and 160 and has a function of accurately detecting the open and closed positions of the first case 100.

The position detecting target 170 is located in the first case 100, and the sensing means 150 and 160 for detecting the same are located in the second case 200. At this time, the sensing means 150 and 160 are constituted by the at least two. Is spaced apart by the movement distance h, i.e., the movement stroke, during the opening and closing of the first case 100. In FIG. 5, one of the sensing means 150 is mounted at a position capable of detecting the target 170 in the closed position of the first case, and the other 160 is mounted at the open position of the first case. 170) is mounted in a position capable of detecting.

Preferably, the position detecting target 170 is the first case 100 and the second case 200 when the first case 100 is fully open with respect to the second case 200 It is mounted on the overlapping part. That is, as shown in FIG. 5, since the position detecting target 170 should be a position that can be detected by the sensing means 150 and 160 located in another case, that is, the second case 200, even in a completely open state. The two cases should be areas where they can overlap each other. If the target 170 is located at a position not overlapping with the second case, a problem may occur that the state of the first case cannot be detected.

In addition, the position detection target 170 may be preferably a magnet (magnet). In this case, the sensing means 150 and 160 use a non-contact sensor that can detect the magnetic force of the magnet. The non-contact sensor can be of various kinds, such as a Hall sensor composed of Hall ICs, and a sensor using a magnetoresistive element (MR element).

In addition, as shown in FIG. 6A, the position detecting target 170 may be formed as a protrusion 195 protruding from one side of the first case 100. The protrusion 195 is integrally formed with the first case, and the second case 200 is formed with a thin dome-shaped switch 190 which is also protruded.

The drive control unit 500 receives a signal for starting to drive 501, detects the position of the first case through the detection means 150 and 160, and controls the driving direction of the drive motor 300 through the detection signal. And transmits a driving signal whose driving direction is determined to the driving motor to drive the motor.

The present invention not only provides a slide phone having the above configuration, but also provides an automatic driving method of the slide phone. In the automatic slide phone driving method according to the present invention, the slide phone includes a first case and a second case mounted with portable mobile communication components and configured to slide by a driving motor to perform an opening and closing operation. The first case and the second case are as shown in FIGS. 3 to 5.

In the automatic slide phone driving method according to the present invention comprises the following steps. 8 is a flowchart illustrating a method for automatically driving a slide phone according to the present invention.

a. Applying a driving signal to the driving control unit;

First, an initial drive signal for moving the slide phone to the open or closed position is applied to the drive control unit. The driving signal may be generated by the operation of the opening and closing operation switch mounted on the first case or the second case. A driving switch may be formed to provide a driving signal to the first case or the second case, and the user may start the opening and closing operation of the slide phone by pressing the driving switch. In addition, the drive switch is not formed separately, it is also possible to use a button having another function formed on the side.

In addition, the driving signal may be generated by at least two sensing means for detecting the positional deviation of the target for position detection. The user can send the opening and closing operation start signal of the slide phone by pressing the drive switch described above, but it is also predictable to open and close the case manually. If the case is open, the user will close the case manually rather than a button. At this time, the slide phone driving method according to the present invention is to automatically perform the operation that the first case is completely closed (or opened). To this end, the driving signal is applied by detecting the positional deviation of the position detecting target by the sensing means. The sensing means recognizes that the position sensing target is located at the opening and closing position of the first case, and when the position sensing target is not recognized, that is, when the position sensing target is out of position, the signal is sent to the driving control unit. Is applied to give a start signal. The driving signal applying operation by the sensing means as described above can be referred to as a semi-automatic driving mode.

b. The initial position of the position detecting target mounted on the first case is sensed by at least two sensing means arranged in the second case spaced apart by the first case moving distance, and determines the driving direction of the driving motor, driving direction Applying the determined drive signal to a drive motor;

When the driving signal is applied to the driving control unit as in step a, the driving control unit detects the position of the first case by the sensing unit. The first case is equipped with a position sensing target 170 as shown in FIG. 5, so that the position sensing target 170 is detected by at least two sensing means 150 and 160 installed in the second case 200. do. The sensing means are arranged spaced apart by the movement distance h, or stroke, of the first case. In the closed state in FIG. 5, the target 170 is arranged in the same line as the upper sensing means 150, and in the open state, the target 170 is arranged in the same line as the lower sensing means 160. do.

When the first case is completely open with respect to the second case, the target is preferably mounted at a portion where the first case and the second case overlap each other. In the present invention, since the target 170 is mounted to the first case 100 and the sensing means 150 and 160 are mounted to the second case 200, the position of the target is at a position that can be detected by the sensing means of the second case. Therefore, it is preferable that the target 170 is positioned at a portion overlapping with the second case even when the first case is completely opened.

In this case, the position detecting target may be a magnet, and the at least two sensing means may be a non-contact sensor for detecting a magnetic force of the magnet. As the sensing means 150 and 160, a non-contact sensor capable of detecting a magnetic force of the magnet is used. The non-contact sensor may be any of various types such as a Hall sensor composed of a Hall IC and a sensor using a magnetoresistive element (MR element). do. In particular, in the case of Hall sensors, if a magnet is detected, a high signal is generated. If not, a hall signal generates a low signal.

The position detecting target may be a protrusion protruding from one side of the first case, and the at least two sensing means may be a thin plate domed switch formed on one side of the second case. The shape of the thin dome switch at this time is the same as in FIGS. 6A and 6B described above.

In step b, the position of the first case is sensed using the target and the sensing means having the above structure, and accordingly, the driving direction of the driving motor is determined. That is, when the first case is detected as being open with respect to the second case, the driving motor determines the driving direction so that the driving motor can drive the first case to the closed position, and again the driving signal in which the driving direction is determined is driven again. To be applied. When the first case is in the closed position, the driving signal in the direction of driving the first case to the open position is applied in reverse.

c. Applying a driving stop signal to the driving motor when one of the at least two sensing means detects the position detecting target within a predetermined time (s);

After the step b, a driving signal having a driving direction determined is applied to the driving motor, and the first case is moved to an open or closed position by the driving motor. At this time, if the target of the first case 100 is detected again by a sensing means different from the first contacting means, the operation of the drive motor is stopped.

That is, when the target 170 is in contact with the upper sensing means 150 of the second case in the first case in the first closed position, the first case is moved to the open position by the driving of the driving motor 300, The target 170 of one case is in contact with the lower sensing means 160. When the lower sensing means 160 senses the position sensing target, it sends a signal to the driving controller, and the driving controller applies a driving stop signal to the driving motor. At this time, it is necessary to detect the position within a predetermined time (s) in the sensing means other than the first sensing means. This is explained in more detail in step d below.

Preferably, the automatic driving method of the slide phone according to the present invention further includes the following d step.

d. Applying a driving signal in a direction opposite to a driving direction to the driving motor when the position of the position sensing target is not detected for both of the at least two sensing means for a predetermined time (s);

As described above, the automatic driving method of the slide phone according to the present invention is completed by sequentially performing steps a to c, and also preferably performing the step d. In step d, when the driving motor starts to drive and the position detection target position is not detected for a predetermined time (s), the driving signal in the opposite direction to the driving direction is applied to the driving motor again, and step c is performed again. .

During the automatic opening and closing of the slide phone, an external force may be applied to the slide phone, thereby preventing the slide phone from being fully opened or closed. In this case, for example, the user prevents the case from being opened to close again during the opening operation. When a load is applied from the outside during the automatic operation, the first case that is slid in between stops. At this time, the load of the geared motor is applied to the maximum, and the current flows as much as the starting current. do.

In order to solve this problem, if the position of the target is not detected by the sensing means for a predetermined time (s), it is determined that the movement of the first case is disturbed by the action of the external force, thereby reversing the driving direction of the driving motor. . At this time, the designated time (s) is given a time of about twice the opening and closing time. That is, if the operation time operating from the closed position to the open position is 0.5 seconds, the specified time s is designated as 1 second. By this method it is possible to solve the problem that may occur when the load is applied from the outside during the automatic operation.

In the automatic driving method of the slide phone according to the present invention, as described above, the drive motor slides the first case with respect to the second case through the pinion gear connected to the drive motor and the rack gear engaged with the pinion gear. Can be operated. In addition, the driving motor may slide the first case with respect to the second case through a friction difference connected to the driving motor.

The present invention not only provides an automatic driving method of a slide phone including each step as described above, but also provides a method for detecting an incoming signal of an automatic driving type slide phone. In the incoming signal detection method according to the present invention, the slide phone includes a first case and a second case mounted with portable mobile communication components, and configured to slide by a driving motor to perform an opening and closing operation. The first case and the second case are as shown in FIGS. 3 to 5.

In the incoming signal detection method according to the present invention comprises the following steps. 9 is a flowchart illustrating a method for detecting an incoming signal of an autonomous slide phone according to the present invention.

a. Receiving a communication signal from the outside;

Receive a call from outside. That is, the call signal is received by the main controller of the terminal via the antenna of the user terminal. In this case, the main control unit is usually a component having a small computer function such as a microcomputer.

b. Applying a signal to a driving control unit of the slide phone when an incoming call is detected;

When receiving a communication signal from the outside and the main control unit detects it, the signal indicating that the call is received is applied to the driving control unit of the slide phone. As shown in FIG. 7, the driving controller performs a function of supplying or cutting off power to the driving motor, and is connected to the sensing means to receive a signal from the sensing means to control the driving.

c. Determining an initial rotation direction of a driving motor by the driving controller according to the opening / closing state of the first case; And

When the incoming signal is applied to the driving control unit as in the above steps, the driving control unit determines the initial rotation direction of the driving motor according to the opening / closing state of the first case. Preferably, the open / closed state of the first case may be sensed through the position detecting target and the sensing means.

That is, as described above, the first position detecting target 170 is mounted, and the position detecting target 170 is mounted by the at least two sensing means 150 and 160 installed in the second case 200. Will be detected. This is shown in detail in FIG. 5. The sensing means are arranged spaced apart by the movement distance h, or stroke, of the first case. In the closed state in FIG. 5, the target 170 is arranged in the same line as the upper sensing means 150, and in the open state, the target 170 is arranged in the same line as the lower sensing means 160. do.

When the first case is completely open with respect to the second case, the target is preferably mounted at a portion where the first case and the second case overlap each other. In the present invention, since the target 170 is mounted to the first case 100 and the sensing means 150 and 160 are mounted to the second case 200, the position of the target can be detected by the sensing means of the second case. It is preferable that the target 170 is located at a portion overlapping with the second case even when the first case is completely opened.

In this case, the position detecting target may be a magnet, and the at least two sensing means may be a non-contact sensor for detecting a magnetic force of the magnet. As the sensing means 150 and 160, a non-contact sensor capable of detecting a magnetic force of the magnet is used. The non-contact sensor may be any of various types such as a Hall sensor composed of a Hall IC and a sensor using a magnetoresistive element (MR element). do. In particular, in the case of Hall sensors, if a magnet is detected, a high signal is generated. If not, a hall signal generates a low signal.

The position detecting target may be a protrusion protruding from one side of the first case, and the at least two sensing means may be a thin plate domed switch formed on one side of the second case. The shape of the thin dome switch at this time is the same as in FIGS. 6A and 6B described above.

In this step, the position of the first case is sensed using the target and the sensing means having the above structure, and the driving direction of the driving motor is determined accordingly. That is, when the first case is detected as being open with respect to the second case, the driving motor determines the driving direction so that the first case can be driven to the closed position, and in reverse when the first case is in the closed position. The driving direction is determined to drive the first case to the open position.

d. Applying an operation signal to the drive motor of the slide phone by the drive control unit to repeat the opening and closing operation with respect to the second case;
