The present invention relates to a rotation angle control device for an operating toy, and more particularly, to rotate various members of the operating toy at a desired angle without using a motor and a reduction gear for rotating the various members of the operating toy at a specific angle. The present invention relates to a rotation angle control device for an operation toy, which makes it possible to lower the price of the operation toy and minimize the volume of the rotation angle adjustment device.

In general, a variety of toys for mimicking the motion of a person or animal is a related rotating member (rotating member corresponding to the cervical vertebrae) for the purpose of nodding the head, opening and closing the mouth, turning the pupil, lifting the arm, and the like. , A rotating member corresponding to the lower jaw, a rotating member for turning the pupil, a rotating member corresponding to the arm joint, etc.) should be controlled to rotate at a desired angle.

However, in the related art, in order to rotate such a rotating member at a desired angle, a speed reducer is used to reduce the rotation generated by the motor together with the motor, thereby reducing the rotational power of the motor by the reducer to rotate the rotating member and the desired angle. The encoder detects whether the motor is rotated by the encoder and controls the motor to rotate at the desired angle.

However, when the motor and the reduction gear are used as a component for generating the driving force for the rotating member of the operating toy as described above, the volume of the operating toy becomes very large due to the volume of the motor and the reduction gear, and the operating time of the motor and the reduction gear is reduced. If this considerably elapses, a breakdown will occur easily, and it becomes difficult to provide the angle control apparatus for the rotating member which is small and durable.

In order to solve the problem of such a large volume, it is possible to use a very small motor (miniature motor) and a reduction gear, the use of this method has a problem that the manufacturing cost of the operating toy increases because the cost of the parts is very expensive. .

In particular, when the motor is used, the power consumption is high and the torque reduction by the speed reducer is severe. When the rotary member of the battery-operated toy is operated frequently, the power consumption becomes large and the battery must be replaced frequently.

The present invention is to solve the above problems, in the rotation angle control device of the rotating member of the operating toy, a compact, low power consumption and durable rotation angle control device without using a motor and a reduction gear to provide.

In order to achieve the above technical problem, this invention,

First and second magnets M1 and M2 installed to be spaced apart from each other by a predetermined distance and having opposite polarities; It is fixed to the base, the coil is wound, is installed in the lower portion of the first and second magnets (M1, M2), when the current is applied to the first magnet (M1) or the second magnet (M2) Generating a polarity and determining a rotation angle and a rotation direction according to the magnitude and direction of the current; First and second magnets (M1, M2) fixedly installed at one end thereof, and a rotation member (2) rotatably installed around a hinge (4) fixed to the base;

It characterized in that it comprises a spring (3, 3a, 3b, 3c) coupled to the rotating member (2).

First, the principle of the rotation angle control device of the present invention will be described with reference to FIGS.

 In Fig. 1, the rotating member 2 is rotatably coupled to the hinge 4, the spring 3 is wound around the hinge 4, and one end 3a is elastically coupled to the fixing protrusion 5 and the other side. Is elastically coupled to the projection 6 on the rotating member (2). And magnets M1 and M2 of opposite polarities are installed on both sides of the T-shaped blades of the rotating member 2, and the coil 1 is fixed to the base on which the hinge 4 is fixed.

In this case, the rotating member 2 is a rotational force (Fg) to rotate in a counterclockwise direction about the hinge (4) by the weight acts, the spring 3 is rotated by one end (3b) Rotational force (Fs) to rotate the clockwise action.

Now, when a current is applied to the coil 1 so that the N pole is formed in the coil 1, the repulsive force between the N pole formed by the coil 1 and the N pole of the magnet M1 and the coil 1 By the suction force between the N pole formed by the S pole and the S pole of the magnet M2, the rotating member 2 has a rotation force Fc to rotate in the counterclockwise direction.

This rotational force Fc is a state in which both the magnet M1 and the magnet M2 are in the upper upper part of the coil 1 as shown in Fig. 1 (the magnet M1 and the magnet M2 are both coils 1). In the state of magnetic flux that crosses most of the magnetic flux in the magnetic flux, the state is the strongest, but the state in which the magnet M1 tries to leave the coil 1 as shown in FIG. 2 (the magnetic M2 is within the magnetic flux of the coil 1). However, in the state in which the magnet M1 tries to escape the magnetic flux of the coil 1 and the intersecting magnetic flux starts to decrease from this time, the magnet M1 begins to decrease. As shown in FIG. In the state of leaving the coil 1 and only the magnet M2 in the coil 1 (a state in which the intersecting magnetic flux is further reduced), it is further reduced, so that even the magnet M2 leaves the coil 1 (not shown) ( In the state where the intersecting magnetic flux is considerably reduced), it becomes weak.

Therefore, when a constant current is applied, the rotation force Fc is attenuated as shown in FIG. 4 in inverse proportion to the rotation angle in the counterclockwise direction. In addition, the larger the current applied to the coil 1, the more magnetic flux is formed, so the rotational force Fc becomes larger.

Accordingly, as shown in FIG. 4, a rotation force Fc having different attenuation parabolas is formed according to the current applied to the coil 1.

In addition, since the counterclockwise rotational force (Fg) according to gravity is constant, the rotational force (Fc + Fg) in the counterclockwise direction gradually decreases as shown in FIG. 4 and decreases as it rotates in the counterclockwise direction. Close to.

On the other hand, the clockwise rotational force Fs by the spring 3 increases linearly in proportion to the rotation angle, thereby forming a straight line as in FIG.

Now, the counterclockwise rotational force Fg by gravity and the counterclockwise rotational force Fc when the current is applied to the coil 1, that is, the counterclockwise rotational force Fg + Fc, are added. The rotating rotating member 2 decreases as the rotation angle increases as shown in FIG. 4, but the clockwise repulsive force Fs by the spring 3 increases gradually as it rotates counterclockwise, thereby counterclockwise at any angle. The rotational force Fg + Fc and the clockwise rotational force Fs become equal, and at this angle, the rotation member 2 stops rotating in the counterclockwise direction. That is, in FIG. 4, the rotation is stopped at the rotation angle where the (Fg + Fc) parabola and the Fs straight line intersect.

Since the larger the current applied to the coil 1, the larger the rotational force (Fc), the greater the magnitude of the current applied to the coil 1 as the rotation stop angle of the rotating member 2 is larger as shown in FIG. .

Therefore, if the user wants to rotate at a small angle, a small current may be applied to the coil 1, and if a user wants to rotate at a large angle, a large current may be applied to the coil 1. You choose.

Meanwhile, in the above description, the counterclockwise rotation force Fg due to the gravity of the rotating member 2 is described as present. However, when the rotation force Fg is large, the counterclockwise rotation force Fg + Fc is too large for the rotation force Fg. Since it is dependent on the rotation angle (Fc) it is difficult to adjust the rotation angle.

Therefore, it is preferable to have almost no rotation force Fg. To this end, the weight of the rotation member 2 is adjusted so that the rotation member 2 is balanced around the hinge 4, or FIG. As in the center portion of the T-shaped lower end of the rotating member (2) by placing a center adjustment screw (11) for arranging the weight may be so that the center of gravity is almost at the hinge (4).

In addition, as shown in FIG. 6, when the magnetic plate is installed between the magnet M1 and the magnet M2 by the iron plate, the magnetic flux is released into the space, and the magnetic flux is not moved to the iron plate. Since it flows into the collector plate 12 without any loss of magnetic flux, a larger rotational force can be obtained even when a magnet of the same strength is used.

As a result, the present invention uses the principle that the rotating member 2 stops rotating at an angle in which the rotating force Fc by the electromagnet of the coil 2 and the repulsive force Fs by the spring 3 are balanced.

Next, FIG. 1 illustrates a case in which the rotating member 2 rotates counterclockwise at an angle according to the magnitude of the current applied to the coil 1 and stops (one-way rotation method). Depending on the direction and magnitude of the current applied to (1), it is also possible to rotate a certain angle clockwise and counterclockwise and then stop (bidirectional rotation type). This bidirectional rotation method will be briefly described with reference to FIGS. 7-10.

As shown in FIG. 7, when the bidirectional springs 3a and 3b are installed, a graph as shown in FIG. 8 is formed to rotate in both directions.

By the way, in the bidirectional spring 3 as shown in Fig. 7, when the rotary member 2 rotates counterclockwise, the projection 6a provided on the rotary member 2 pushes the spring 3a and rotates clockwise. As the projection 6a pushes the spring 3b, the center position is balanced so that the center position is correct, but if it does not rotate until more than a certain amount of current is applied to overcome the balance and rotate, There is a difficulty in rotating the minute angle because the discontinuous motion moving for rotation.

In order to overcome the difficulty of the minute angular rotation in the vicinity of the center, the spiral spring 3c is used in FIG. 9 so that one end of the spiral spring 3c is rotated and wound like the rotating member 2 in the hinge 4. When coupled and the other end is fixed to the protrusion fixed to the base, as if to perform the action of winding or unwinding the clockwork by the rotation of the rotating member 2, a graph as shown in Figure 10 is formed to form a near Even in the case of a minute current is possible a continuous operation that enables a fine rotation.

On the other hand, the present invention can be variously modified to arrange the coil and the magnet as shown in Figure 11 so that this principle is applied. In FIG. 11, each layer is shown as being far apart for convenience of illustration, so that each layer is preferably arranged as close as possible.

FIG. 11A illustrates a structure in which the magnetic collecting plate 12 is located above the magnets M1 and M2 and the coil 1 exists below. FIG. 11 (b) shows the case where the coils 1-1 and 1-2 are located at the upper and lower portions, respectively, and the magnets M1 and M2 exist in the middle. FIG. 11 (c) shows the coil 1 at the middle and the upper and lower parts. The pair of magnets M1 and M2 and the magnets M3 and M4 are installed in the housing, and the magnetic collecting plates 12-1 and 12-2 are provided.

On the other hand, in Fig. 11 (a) to Fig. 11 (c), the rotating member may be provided in any layer. For example, in FIGS. 1 and 6, magnets M1 and M2 are installed in the rotating member 2 and the coil 1 is fixed to the base. However, the magnets M1 and M2 are fixed to the base. It is also possible to have a structure in which the coil 1 is installed on the rotating member 2.

Next, the head of the operating toy to which the rotation angle control device to which the principles of the present invention are applied as described above will be described. 12 is a front view and a side view of the head of the actuating toy, and FIG. 13 is a cutaway detail view. Although not shown, the present invention can also be used as a rotation angle control device for rotating the pupil or a rotation angle control device for rotating the neck left and right. In addition, when the pupil rotation angle control device is used, various pupil expressions as shown in FIG. 14 can be produced.

As shown in Fig. 13, a rotation angle control device as shown in Figs. 1 and 7 is provided at each of the neck joint part for shaking the head and the jaw joint part for opening and closing the mouth.

In the rotation angle control device 20 of the wooden joint portion, the wooden joint 21 is fixed to the body as shown in FIG. 13, and a magnet (installed in the lower part of the magnetic collecting plate 25) and the magnetic collecting plate 25 are the wooden joints ( 21, the spring is a bidirectional spring as in FIG. 7, so that this fixed head 23 is in accordance with the direction and magnitude of the current applied to the coil 22 in the principle as shown in FIG. The angle 24 is rotated back and forth around the hinge 24. Here, the rotation angle control device 20 of FIG. 13 has a structure in which a magnet is installed at the neck joint 21 and a coil 22 is installed at the head 23 as opposed to FIG. 7.

In the rotation angle control device 30 of the jaw joint portion, the coil 31 is fixedly installed and the lower portion of the rotating member 32 is fixed to the jaw joint 33 so that the rotation is performed according to the principle shown in FIGS. 1 and 4. When the member 32 rotates at an angle, the jaw joint 33 fixedly coupled thereto rotates to open and close the mouth.

Next, by adjusting the waveform of the current applied to the coil in the rotation angle control device of the present invention, it is possible to make a sound.

If the current applied to the rotating member in FIG. 1 vibrates about several hundred Hz about a specific current value as shown in FIG. 15, the rotating member 2 vibrates finely during this period but is invisibly visible. The sound of the vibration of the ringing through the inner skull member of the head portion, the sound can be adjusted by adjusting this frequency can produce a sound of the desired frequency.

Finally, as shown in FIG. 16, when the pulse sensing circuit 41 is installed in the coil 40 of the rotation angle control device of the present invention, when the operating member is touched in a state where the rotation angle control device is stopped, the rotation member is caused by this touch. Rotates slightly at an angle so that a voltage waveform is generated in the coil 40 and a pulse is generated when the pulse wave is generated, thereby recognizing that the vicinity of the portion where the rotating member is installed is touched by the pulse. The device may also serve as a touch sensor.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this embodiment, but various modifications and changes can be made without departing from the spirit of the present invention.

By using the present invention as described above, it is possible to provide a rotation angle control device that is small in size, low in power consumption and high in durability without using a motor and a reduction gear.
