Description

    The present invention relates to a portable terminal that allows a user to recognize an incoming call by vibration and automatically opens a lid from a main body.

  As shown in FIG. 4 showing an open state, the mobile phone 100 according to one aspect of the mobile terminal includes a main body 101 in which a control unit (not shown) is housed, and a hinge 103 coupled to the main body 101 so as to be freely opened and closed. The lid body 102 is provided.

  The main body 101 is provided with a plurality of numeric keypads 104 for operating the mobile phone 100, a multifunction key keytop 105, a decision key keytop 106, and the like, which are exposed to the outside. In 102, a liquid crystal display unit 107 for displaying various kinds of information is arranged.

  The mobile phone 100 is used by opening the lid 102 from the main body 101 when used for calling or sending / receiving e-mail, as shown in FIG. Closed to the main body 101 as shown by an arrow β.

  In recent years, the cellular phone 100 has become smaller and thinner due to high integration of ICs and the like, making it difficult to open and close the cellular phone 100.

For this reason, a device having a function of automatically opening the lid 102 closed on the main body 101 of the mobile phone 100 by a spring or a motor has been developed and distributed in the market (for example, Patent Document 1).
JP 2005-252492 A

When the mobile phone 100 receives an incoming call, the eccentric weight 109 is rotated by a motor m2 as indicated by an arrow as shown in FIG. A mechanism for vibrating the telephone 100 is provided in the main body 101.

On the other hand, as shown in the conceptual diagram of FIG. 5 (b), the mechanism for opening the closed lid 102 on the main body 101 of the mobile phone 100 is a motor gear g that is driven by a motor m3 that is different from the motor m2. An open mechanism O1 for automatically opening the lid body 102 is driven through this.

  As described above, since the motor m3 or the spring mechanism (not shown) dedicated to the open mechanism O1 is separately required, the occupied space in the main body 101 is increased, and the overall size of the mobile phone 100 is increased as the occupied area is increased. This increases the size of the mobile phone 100 and goes against the trend toward smaller and thinner mobile phones 100.

  Further, since mechanical parts such as the motor m3 dedicated to the open mechanism O1 are used, there is a disadvantage that the configuration becomes complicated and the manufacturing cost increases.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a portable terminal that can be miniaturized and can electrically control the opening mechanism of the lid.

    In order to achieve the above object, a mobile terminal according to claim 1 of the present invention includes a main body and a lid that can be opened and closed to the main body, and generates a vibration for recognizing the incoming call when there is an incoming call. A portable terminal that automatically opens the lid closed to the main body, and a motor that rotates forward and reverse, and a vibration generating means that generates vibration by a driving force of rotation of the motor in one direction when there is an incoming call; And a lid opening means for opening the lid body closed to the main body by a driving force of rotation in the other direction of the motor.

  According to a second aspect of the present invention, there is provided a portable terminal according to the first aspect, wherein the portable terminal further rotates with the rotation of the motor in one direction to transmit a driving force and the other direction of the motor. A first one-way clutch that rotates idly for rotation and a second one-way clutch that rotates as the motor rotates in the other direction and transmits a driving force and rotates idly in one direction of the motor. The vibration generating means is connected to the motor via the first one-way clutch, and when there is an incoming call, the driving force of rotation of the motor in one direction is transmitted via the first one-way clutch, The lid opening means is connected to the motor via the second one-way clutch, and the driving force of rotation in the other direction of the motor is the second one-way clutch. It is transmitted through.

  According to a third aspect of the present invention, in the portable terminal according to the second aspect, when the operation of closing the lid is performed, the second one-way clutch and the lid opening means are separated.

  According to a fourth aspect of the present invention, in the portable terminal according to any one of the first to third aspects, in the process of opening the lid closed to the main body by the lid opening means. And a control means for preferentially controlling the operation of opening the lid when there is an incoming call.

    As described above in detail, the portable terminal according to claims 1 and 2 of the present invention includes a drive source of vibration generating means for generating vibration for notifying an incoming call when a call is received, and a lid closed on the main body. Since the drive source of the lid opening means for opening is shared by one motor, the portable terminal can be made smaller and thinner.

  Further, since the function of vibration and the function of opening the lid are switched depending on the rotation direction of the motor, electrical control can be performed.

  Since the portable terminal according to claim 3 of the present invention separates the second one-way clutch and the lid opening means when the operation of closing the lid is performed, the vibration of the vibrating means is generated by the operation of closing the lid. This prevents the user from misidentifying an incoming call.

  Since the portable terminal according to claim 4 of the present invention includes control means for preferentially controlling the operation of opening the lid when there is an incoming call in the process of opening the lid by the lid opening means, the usability is good.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  A mobile phone (mobile terminal) 1 to which the present invention is applied includes a control unit (not shown) inside as shown in FIG. 1 (a) in a front view in an open state and FIG. 1 (b) in a right side view. And a lid 3 that is coupled to the main body 2 so as to be openable and closable.

  The main body 2 is provided with a plurality of ten-key key tops 5 for operating the mobile phone 1, a multifunction key key top 6, an enter key key top 7 and the like exposed to the outside. The lid 3 is provided with a liquid crystal display unit 8 on which various information is displayed.

  The mobile phone 1 is used by opening the lid 3 from the main body 2 during a call or when using for transmission / reception of e-mail, as shown in FIGS. 1 (a) and 1 (b). Thus, the lid 3 is used by being closed to the main body 2 (see FIG. 1C).

  When the main body 2 is opened (see FIGS. 1A and 1B) from the state in which the main body 2 of the cellular phone 1 is closed, the cover open button (not shown) is pressed. This is done by driving an electric open mechanism (lid opening means) O (described later) disposed in the main body 2, while the cellular phone 1 is changed from an open state to a closed state. Is done manually.

  In addition, the mobile phone 1 is configured to vibrate by a vibration mechanism V (described later) disposed in the main body 2 when a call is received, so that the user can recognize the call.

As shown in FIG. 2 of the conceptual diagram, the vibration mechanism V is fixed to the motor m1, which is a driving source, a one-way clutch (first one-way clutch) c1 fixed to the rotating shaft j of the motor m1, and the one-way clutch c1. And an eccentric eccentric weight (vibration generating means) w.

The one-way clutch c1 rotates by rotating the rotation axis j in the direction of arrow β1, and rotates the eccentric weight w. However, the rotation of the rotation axis j in the direction of arrow β2 idles and does not rotate the eccentric weight w. .

As shown in FIG. 2, the open mechanism O uses the same motor m1 as the vibration drive source described above, and a one-way clutch (second one-way clutch) c2 fixed to the rotating shaft j of the motor m1. It is connected to the motor m1 of the driving source.

The one-way clutch c2 does not transmit the driving force of the motor m1 to the open mechanism O with respect to the rotation of the rotation axis j in the direction of the arrow β1 in one direction, but rotates in the direction of the rotation axis j in the direction of arrow β2 in the other direction. Rotate the motor m1 and transmit the driving force of the motor m1 to the open mechanism O.
Is driven to open the lid 3 (see FIG. 1C) closed to the main body 2 in the direction of the arrow α2.

  Also, a lid open detection hall element (not shown), which is a detection means for detecting the fully open state of the main body 2 (see FIG. 1B) in the mobile phone 1, is provided in the vicinity of the hinge 4 of the main body 2. A lid open detection magnet (not shown) that generates a magnetic field detected by the Hall element is provided in the vicinity of the hinge 4 of the lid 3 so as to approach the Hall element when the lid 3 is fully opened. Yes.

  When the lid 3 of the cellular phone 1 is fully opened (see FIG. 1B) by the detection means, the lid open detection magnet near the hinge 4 of the lid 3 is near the hinge 4 of the main body 2. And the Hall element detects the magnetic field of the magnet to generate a voltage, and detects that the lid 3 of the mobile phone 1 is fully opened.

  Next, operations of the vibration mechanism V and the open mechanism O will be described.

When the mobile phone 1 receives an incoming call, the control circuit controls the motor m1 to rotate at high speed in the direction of the arrow β1, rotates the eccentric weight w via the one-way clutch c1, and generates a swinging motion. Vibrate to let the user recognize the incoming call.

  When the motor m1 rotates in the direction of arrow β1, the one-way clutch c2 connected to the open mechanism O rotates idly, so that the power of the motor m1 is not transmitted to the open mechanism O.

  On the other hand, when the lid 3 of the mobile phone 1 is closed (see FIG. 1C), the user opens the lid 3 of the mobile phone 1 (see FIGS. 1A and 1B). If so, press the lid open button.

When the lid opening button is pressed, the control circuit rotates the motor m1 in the direction of arrow β2, so that the rotation shaft j rotates in the direction of arrow β2, and the driving force of the motor m1 is changed to the one-way clutch c2.
Is transmitted to the open mechanism O.

When the opening mechanism O is driven, the lid 3 closed to the main body 2 of the mobile phone 1 shown in FIG. 1C opens in the direction of the arrow α2, and when the front open state shown in FIG. Magnet closes to the lid open detection hall element, a voltage is generated in the hall element to detect the fully opened state, the control circuit stops the rotation of the motor m1 in the direction of arrow β2, and the lid body 3 opens. Stopped.

  When the motor m1 rotates in the direction of arrow β2, the one-way clutch c1 connected to the vibration mechanism V rotates idly, so that the power of the motor m1 is not transmitted to the vibration mechanism V.

By the way, when the user closes the lid 3 in the state in which the lid 3 of the mobile phone 1 is opened (see FIG. 1B), it is performed manually, but the user has opened the lid 3 ( When the closing operation is performed in the direction of the arrow α1 from FIG. 1B), the eccentric shaft w rotates when the rotating shaft j rotates in the direction of the arrow β1 via the open mechanism O and the one-way clutch c2 to close the lid 3. Rotates to cause a swinging motion, and vibration is generated.

Therefore, when the user performs an operation of closing the lid 3 in the arrow α1 direction from the opened state,
The operation of the hinge 4 and the gear of the open mechanism O associated with the closing operation of the lid 3 is detected by a detection mechanism (not shown) using a spring or the like, and the open mechanism O and the one-way clutch c2 are disconnected, Occurrence is prevented.

  If the vibration of the main body 2 due to the swinging motion of the eccentric weight w when closing the lid 3 is such that the user does not mistakenly recognize that there is an incoming call, the opening mechanism O and the A configuration in which the one-way clutch c2 is not disconnected is also possible.

Further, from the state where the lid 3 is closed (see FIG. 1 (c)), the user presses the lid opening button and rotates the motor m1 in the arrow β2 direction as shown in FIG. When the driving force of m1 is transmitted to the open mechanism O via the one-way clutch c2 and an incoming call is received while the lid 3 is opening, the lid 3 is opened by the control circuit. Prioritized control is performed.

After the opening operation of the lid 3 is finished, the motor m1 is controlled to rotate at high speed in the direction of the arrow β1 by the control circuit, and the eccentric weight w is rotated via the one-way clutch c1 to generate a swinging motion. Then, the main body 2 is vibrated to make the user recognize the incoming call of the mobile phone 1.

Contrary to the above configuration, if there is an incoming call while the lid 3 is being opened, the control circuit temporarily controls the opening of the lid 3 to stop the motor m1 with an arrow. After controlling the rotation in the β1 direction at high speed, rotating the eccentric weight w through the one-way clutch c1 to generate a swinging motion, and vibrating the main body 2 to make the user recognize the incoming of the mobile phone 1, Again, the motor m1 may be rotationally controlled in the direction of the arrow β2, and the opening operation of the lid 3 may be continued.

  In the above-described embodiment, as shown in FIG. 3A, which is a conceptual side view, the clad shell, that is, the foldable mobile phone 1, in which the lid 3 is folded with respect to the main body 2 as indicated by an arrow. As shown in FIG. 3B, which is a conceptual side view, the above-described vibration is also applied to the slide-type mobile phone 10 that slides the lid 13 with respect to the main body 12 as indicated by an arrow. The vibration mechanism V1 and the open mechanism O2 having the same configuration as the mechanism V and the open mechanism O can be applied.

According to the above configuration, since the drive source of the vibration mechanism V that generates vibration at the time of an incoming call and the drive source of the open mechanism O are shared by one motor m1, the occupied space in the mobile phone 1 is reduced, and the mobile phone 1 Can be reduced in size and thickness.

Further, since the function of the vibration mechanism V and the function of the open mechanism O are switched according to the rotation direction of the motor m1, electrical control can be performed.

    As an application example of the present invention, the mobile phone 1 has been described as an example, but it can be widely used for mobile terminals other than the mobile phone 1.
