Description

The present invention relates to an electronic device such as a transmission operation is carried out by the electromotive force when the power input equipment that can be generated by the operation force from the outside has been operated.

  FIG. 7 of Patent Document 1 describes a basic structure of a self-power generation type key input device.

  This key input device is provided with a core forming a magnetic path and a coil portion wound around the core. Both ends of the core are opposed to each other through a space, and a bar-shaped magnet can intervene in this space. An electromotive force is generated in the coil from a change in magnetic flux in the core when the magnet intervenes in the space and a change in magnetic flux in the core when the magnet leaves the space.

  The key input device described in Patent Document 1 simply moves a magnet in and out of the space without changing the direction of its magnetic pole. Therefore, the direction of magnetic flux does not reverse in the core, the amount of change in magnetic flux in the core is small, and power generation efficiency is poor.

  In this structure, when the magnet is inserted into the space, the magnet is attracted to the end of the core and moves at a relatively high speed. However, when the magnet is removed from the space, the magnet is detached from the space. There is a limit to increasing the separation speed because of the force acting to prevent the movement. Since the electromotive force is proportional to the amount of change in the magnetic flux in the core per unit time, it is induced when the magnet is removed from the space, compared to the electromotive force induced when the magnet is moved into the space. The electromotive force is greatly reduced. In order to increase the electromotive force, it is necessary to use a return spring that exerts a strong force to disengage the magnet from the space. This return spring force acts as a resistance force against the operating force. Will be difficult to operate.

  The transducer described in FIGS. 3 and 4 of Patent Document 2 is provided with stop points facing each other at both ends of a soft magnetic member wound with a coil. A permanent magnet is supported between the soft magnetic members so as to be rotatable about an axis, and a first magnet layer and a second magnet layer are superimposed on both surfaces of the permanent magnet. Both end portions of the first magnet layer and both end portions of the second magnet layer face each other in parallel, and a stop point of the soft magnetic member enters between them.

  When the permanent magnet rotates clockwise, one end portion of the first magnet layer and one end portion of the second magnet layer are magnetically attracted and fixed to the stop point of the soft magnetic member, and counterclockwise. When rotating, the other end of the first magnet layer and the other end of the second magnet layer are magnetically attracted and fixed to the stop stop of the soft magnetic member. This transducer also generates an electromotive force in the coil due to a change in the magnetic flux in the soft magnetic member when the permanent magnet rotates in the clockwise direction and a change in the magnetic flux in the soft magnetic member when the permanent magnet rotates in the counterclockwise direction. Is generated.

  In the transducer described in Patent Document 2, the first magnet layer and the second magnet layer are attracted to the soft magnetic member both when the permanent magnet rotates clockwise and when it rotates counterclockwise. Therefore, a very large force is required to rotate the permanent magnet in the reverse direction from this attracted and fixed state. The transducer is provided with a return spring for returning the permanent magnet to the same posture. In this regard, Patent Document 2 uses a return spring that exhibits a force larger than the magnetic holding force at the stop point. It is explained that it is necessary. Therefore, when rotating the permanent magnet, the force required to separate the first magnet layer and the second magnet layer from the stop point and the force against the return spring are required. If an excessive operating force is not applied, it cannot be operated.

  The connecting pin 14 and the connecting elongated hole 16 constitute a connecting mechanism that converts the moving force of the operating member 15 in the vertical direction (Y direction) into turning power about the axis O of the rotating body 10. Yes.

  As shown in FIGS. 3 and 4, a return spring 17 is provided inside the housing 2, and the operation member 15 is always urged in the Y1 direction (return direction) by the return spring 17.

  In the rotating body 10, the magnetic flux generator 20 is fixed to the rotating holder 11. The magnetic flux generator 20 is located in the space 8 where the first opposing end 4a and the second opposing end 4b of the magnetic path forming member 3 are opposed to each other. As shown in FIGS. 3 and 4, the magnetic flux generator 20 has a permanent magnet 21. The permanent magnet 21 is a plate-shaped magnet, and one flat surface facing the top and bottom is the first magnetized surface 21a and the other flat surface is the second magnetized surface 21b. The first magnetized surface 21a and the second magnetized surface 21b are magnetized with opposite polarities. In the example shown in FIGS. 3 and 4, the first magnetized surface 21a is magnetized to the S pole and the second magnetized surface 21b is magnetized to the N pole.

  The first magnetizing member 22 is fixed to the first magnetized surface 21a, and the second magnetizing member 23 is fixed to the second magnetized surface 21b. The first magnetizing member 22 and the second magnetizing member 23 are soft magnetic metal plates. The first magnetizing member 22 has a first end face 22a facing the X2 side and a second end face 22b facing the X1 side. The second magnetizing member 23 has a first end face 23a facing the X1 side and a second end face 23b facing the X2 side.

  As shown in FIGS. 3 and 4, each end face 22 a, 22 b, 23 a, 23 b is formed in a curved surface shape so as to coincide with a cylindrical surface centering on the axis O that is the center of the rotating shaft 12. . As shown in FIGS. 3 and 4, when the end face 22a of the first magnetizing member 22 or the end face 23b of the second magnetizing member 23 faces the first opposing end 4a, the end face 22a or the end face 23b and the second face The first facing end 4a does not come into contact with each other, and a fine gap is formed in the facing portion.

  As shown in FIG. 3, the thickness dimension T2 of the first magnetizing member 22 is the same as the thickness dimension T1 of the magnetic path forming member 3, but larger than that, and the first end face 22a of the first magnetizing member 22 is larger. Is opposed to the first facing end 4a, the facing area is not narrower than the area of the first facing end 4a. This is the same when the second end face 22b of the first magnetizing member 22 and the second facing end 4b face each other. Further, the thickness dimension of the second magnetizing member 23 is also T2, and when the end face 23a or the end face 23b faces the opposite end portions 4a and 4b, the opposite area is larger than the area of the opposite end portions 4a and 4b. There is no narrowing.

  When the thickness dimensions T1 and T2 satisfy the above relationship, the transmission efficiency of the magnetic flux from the first magnetizing member 22 and the second magnetizing member 23 to the magnetic path forming member 3 is increased.

  Next, the operation of the power generation input device 1 will be described.

  As shown in FIG. 3, when no external force is applied to the operating member 15, the operating member 15 is returned in the Y1 direction by the biasing force of the return spring 17, and the connecting pin 16 is connected to the connecting pin by the connecting long hole 16 of the operating member 15. 14 is lifted, and the rotating body 10 is in the first posture rotated clockwise in FIG. When the rotating body 10 is in the first posture, the first end surface 22a of the first magnetizing member 22 faces the first facing end 4a of the magnetic path forming member 3 with a small gap therebetween, and the second The first end face 23a of the magnetizing member 23 is opposed to the second opposing end 4b via a minute gap. Further, the second end face 22b of the first magnetizing member 22 is separated from the second opposing end 4b, and the second end face 23b of the second magnetizing member 23 is separated from the first opposing end 4a.

  In the state shown in FIG. 3, the first end face 22a and the first opposing end 4a are magnetically attracted by the magnetic force of the permanent magnet 21, and the first end face 23a and the second opposing end 4b are magnetically attracted. Thus, the rotating body 10 tries to be stabilized in the first posture.

  A push button (not shown) is fixed to the upper portion of the operation member 15. When the operation member 15 is pushed in the Y2 direction from the state of FIG. 3 by the push operation of the push button, the connection pin 14 is pushed downward by the connection long hole 16 of the operation member 15, and the rotating body 10 is rotated counterclockwise. It can be rotated. When the operating member 15 is pushed down to the final end, the rotating body 10 assumes the second posture shown in FIG. In the second posture, the second end face 22b of the first magnetizing member 22 faces the second facing end 4b of the magnetic path forming member 3 via a minute gap, and the first end face 22a is the first end face 22a. 1 away from the opposing end surface 23b. Further, the second end face 23b of the second magnetizing member 23 faces the first opposing end 4a via a minute gap, and the first end face 23a is separated from the second opposing end 4b.

  In the state shown in FIG. 4, the second end face 22b and the second opposing end 4b are magnetically attracted by the magnetic force of the permanent magnet 21, and the second end face 23b and the first opposing end 4a are magnetically attracted. Thus, the rotating body 10 tries to be stabilized in the second posture.

  In a normal push button pressing operation, the downward pressing force is released immediately after the operating member 15 is pressed to the final end in the Y2 direction. When the pressing force is released, the operating member 15 is pushed back in the Y1 direction by the urging force of the return spring 17, and the turning force is applied to the rotating body 10 in the clockwise direction. At this time, the rotating body 10 rotates clockwise from the stable state in the second posture shown in FIG. 4 and returns to the first posture shown in FIG.

  The curve α shown in the diagram of FIG. 5 shows the relationship between the stroke (mm) of the operating member 15 and the reaction force (N) acting on the operating member 15 when the elastic force of the return spring 17 is ignored. Yes. The positive side of the reaction force on the vertical axis is the magnitude of the force acting upward on the operation member 15, and the minus side of the reaction force on the vertical axis is the magnitude of the force acting downward on the operation member 15. That's it.

  In the curve α, (i) is a force that stabilizes the rotating body 10 in the first posture shown in FIG. 3, and (ii) is a reaction that causes the rotating body 10 to escape from the stable state of the first posture. It is the maximum value of the force required when rotating clockwise. (Iii) is the force that stabilizes the rotating body 10 in the second position shown in FIG. 4, and (iv) is the time when the rotating body 1 is moved away from the second position and rotated in the clockwise direction. This is the maximum value of the force required for.

  A straight line β in FIG. 5 shows only a change in the return force applied from the return spring 17 to the operation member 15 when the magnetic attractive force of the magnetic flux generator 20 is ignored. A curve γ is obtained by adding the curve α and the straight line β, and shows a change in the reaction force acting when the operation member 15 is operated in the power generation input device 1 of the embodiment. By setting the elastic force of the return spring 17 as the straight line β, the operation reaction force can always be applied upward. Therefore, if the pressing force acting on the operating member 15 is released after the operating member 15 is pushed downward to reach the second posture in FIG. 4, the rotating body 10 and the operating member 15 are moved to the elastic force of the return spring 17. Thus, the first posture shown in FIG. 3 can be restored.

  In the second posture shown in FIG. 4, the first magnetizing member 22 and the second magnetizing member 23 do not contact the first opposing end 4 a and the second opposing end 4 b, and pass through a minute gap. Facing each other. Therefore, the force required to return the rotating body 10 from the second posture in the clockwise direction is not excessively large, and the rotating body 10 is moved to the first by the elastic force of a normal spring having the characteristic of the straight line β shown in FIG. It can be returned to the posture.

  In the first posture shown in FIG. 3, the first magnetizing member 22 and the second magnetizing member 23 are not in contact with the first opposed end 4a and the second opposed end 4b, and a minute gap Is facing through. Therefore, the force required to rotate the rotating body 10 counterclockwise from the first posture in FIG. 3 does not become excessive. Further, since it is not necessary to increase the elastic force of the return spring 17 so much, the maximum force required to lower the operating member 15 is not too large as shown in FIG. The member 15 is easy to operate.

  In the first posture shown in FIG. 3, the magnetic flux φ1 generated from the permanent magnet 21 is supplied from the end face 23a of the second magnetizing member 23 to the second of the magnetic path forming member 3 via the second opposing end 4b. It is given to the arm 3b. The magnetic flux φ1 follows a path that reaches the first arm portion 3a via the connecting portion 3c of the magnetic path forming member 3, and returns to the first magnetizing member 22 from the first opposed end portion 4a via the end face 22a. In the second posture shown in FIG. 4, the magnetic flux φ2 emitted from the permanent magnet 21 follows a path from the first arm portion 3a to the second arm portion 3b via the connecting portion 3c.

  As indicated by (vi) of the curve γ in FIG. 5, in the power generation input device 1 shown in FIG. 1, when the operating member 15 is pushed in the Y2 direction, the rotating body 10 faces the second posture shown in FIG. 4. And rotate rapidly by magnetic attraction. When the pushing force is removed after the operating member 15 is pushed downward, the rotating body 20 is rapidly rotated by the magnetic attractive force and the elastic force of the return spring 17 toward the first posture shown in FIG. .

  Therefore, when the operating member 15 is pushed in the Y2 direction, the amount of change in magnetic flux per unit time when changing from the magnetic flux φ1 to φ2 in the magnetic path forming member 3 is large, and the power generating coils 6a and 6b A large induced electromotive force can be obtained. Similarly, when the operating member 15 returns in the Y1 direction, the amount of change in magnetic flux per unit time when the magnetic flux φ2 changes from φ2 to φ1 in the magnetic path forming member 3 is large, and large induction is generated from the power generation coils 6a and 6b. An electromotive force can be obtained.

  Further, since the magnetic flux changes in the opposite direction between φ1 and φ2, the amount of change of the magnetic flux itself is increased, and the induced electromotive force can be increased.

  Thus, as shown in FIG. 5, the power generation input device 1 shown in FIG. 1 does not have an excessive reaction force when the operation member 15 is pressed in the Y2 direction, and the operation member 15 moves in the Y2 direction. The amount of change in magnetic flux per unit time inside the magnetic path forming member 3 can be increased both when pressed and when returning to the Y1 direction, and a large induced electromotive force can be obtained from the power generating coils 6a and 6b. .

  FIG. 6 is a circuit diagram of an electronic device 30 including a plurality of the power generation input devices 1. The electronic device 30 is a transmitter or a remote controller that transmits an operation signal when each power generation input device 1 is operated.

  When the operating member 15 of the power generation input device 1 is pushed in the Y2 direction, the rotating body 10 rotates from the first posture shown in FIG. 3 to the second posture shown in FIG. 4, and is connected in series at this time. A first electromotive force V1 (first induced current) shown in FIG. 7A is generated between the end 31 and the end 32 of the power generating coils 6a and 6b. When the pressing force on the operating member 15 is released and returned by the return spring 17, the rotating body 10 rotates from the second posture toward the first posture, and at this time, the end portions 31 of the power generating coils 6a and 6b are rotated. And the end 32, a second electromotive force V2 (second induced current) is generated.

  The first electromotive force V1 and the second electromotive force V2 having different polarities are discharged from the first electromotive force V1 through the electromotive force line 35 by being charged in the capacitor 34 through the diode group 33 and then discharged. The wavelength of the second electromotive force V2 is slightly increased.

  As shown in FIG. 6, the electromotive force lines 35 of the plurality of power generation input devices 1 are combined into one power line 36. A rectifier circuit 37 is provided in the power line 36, and the electromotive force generated by the power generation input device 1 is converted into a direct current component and supplied to the power input unit of the signal processing circuit 38 and the transmission circuit 39.

  An ON signal line 41 is drawn out from one end 31 of the power generation coils 6 a and 6 b in each power generation input device 1. Each ON signal line 41 is provided with a diode 42, and can pass the first electromotive force V1 as shown in FIG. 7B. Each ON signal line 41 is individually connected to a plurality of ON signal input units 43 provided in the signal processing circuit 38. When any one of the power generation input devices 1 is operated to obtain the first electromotive force V1, an ON signal having a voltage value set by the resistor R1 is individually supplied from the ON signal line 41 to the signal processing device 38. When the ON signal from each power generation input device 1 is individually input, the signal processing circuit 38 can identify which power generation input device 1 is operated.

  An OFF signal line 44 is drawn from the other end 32 of the power generation coils 6a and 6b in each power generation input device 1. The OFF signal lines 44 of all the power generation input devices 1 are assembled in a common line 45. A common diode 46 is connected to the common line 45. Regardless of which power generation input device 1 is operated, the second electromotive force V2 shown in FIG. 7C is applied to the common line 45, passes through the common diode 46, and is determined by the resistor R2. A value OFF signal is provided to the OFF signal input unit 47 of the signal processing circuit 38.

  In the electronic device 30 shown in FIG. 6, when the operation member 15 of any one of the power generation input devices 1 is pushed, the electromotive force is rectified by the rectifier circuit 37 and given to the signal processing circuit 38 and the transmission circuit 39, and signal processing is performed. The circuit 38 and the transmission circuit 39 become operable.

  Further, an ON signal is given to the signal processing circuit 38 by the first electromotive force V <b> 1 emitted from the power generation input device 1. The signal processing circuit 38 identifies which power generation input device 1 has been operated, and a transmission signal corresponding to the operated input generator 1 is given to the transmission circuit 39 and transmitted. The second electromotive force V2 from the power generation input device 1 is given to the signal processing circuit 38 as an OFF signal from the common line 45 regardless of which power generation input device 1 is operated. When the signal processing circuit 38 receives the OFF signal, the transmission of the transmission signal to the transmission circuit 39 is stopped, and the transmission operation ends.

  In the circuit shown in FIG. 6, since the OFF signals are concentrated on one common line 45, the number of circuit wires can be reduced and the circuit configuration can be simplified.
