Description

Apparatus Controlling Head Rotation for Playthings}

The present invention relates to a head rotation angle control device for an operation toy, and more particularly, to an operation toy head rotation control device for controlling the angle of rotating the head of the operation toy up and down / left and right.

In addition, the present invention relates to a head toy and lip opening and closing control device for the operation toy that can control the angle to rotate the head portion up and down / left and right, and can control the angle to open and close the lips.

In general, a variety of toys for mimicking the movement of a person or animal is related to the movement of the head to move up and down and to rotate left and right, opening and closing the mouth, turning the eyes, lifting the arm, etc. The member (rotating member corresponding to the neck bone, rotating member corresponding to the lower jaw, rotating member for turning the pupil, 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, and provides a compact, low power consumption and durable head rotation angle control device without using a motor and a reduction gear.

In addition, the present invention provides an operation toy head rotation and lip opening and closing control device for controlling the angle to rotate the head portion up and down / left and right, and to control the angle to open and close the lips.

Particularly, in the related art, one pair (two pairs) of coils and permanent magnets have to be used for lip opening and top and bottom rotation control, but in the present invention, only one pair of coils and permanent magnets control lip opening and head rotation up and down. It is possible to provide a head rotation and lip opening and closing control device for an operation toy with a simple structure.

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

And a centering member for stopping the left and right rotation of the head 3 at a point balanced with the left and right rotational force of (16).

By using the present invention as described above, the present invention becomes possible to provide a head rotation angle control device for the operation toy small size, low power consumption and high durability without using a motor and a reduction gear.

Particularly, in the related art, it was possible to use one pair (two pairs) of coils and permanent magnets, respectively, for controlling lips opening and closing and rotating the head up and down, but using the present invention described above, only one pair of coils and permanent magnets Opening and closing the head can be controlled, simplifying the structure and reducing the cost, thereby improving productivity.

First, in the head portion of the operating toy (pelican-shaped operating toy) of the present invention to which the head left / right and up / down rotation angle control device and the lip open / close angle control device of the present invention are applied, FIGS. Through the configuration of the present invention will be described. Figure 1 is a side view of the operating toy of the present invention as viewed from the upper right side, Figure 2 is a reference numeral added to Figure 1.

A head 3 is present on the neck 2 fixed to the body 1, and an opening 4 is present at the bottom of the head so that it does not come into contact with the neck 2 when the head 3 is nodding up and down. . In addition, the lower lip member 5 to which the lower leaf stem structure of the perican is attached to the lower part of the head 3 is fixed to the head 3.

The first plate 10 is fixed to the upper part of the neck 2, and the first coil 11 and the second coil 12 are positioned in the front-rear direction and fixed to the upper end of the first plate 10. , Between the first coil 11 and the second coil 12 coincides with the central axis of the neck 2, one side of which is fixed to the first plate 10, and the other side of which rotates the second plate 14. A third rotary shaft 13 is present, and a second plate 14 is rotatably installed on the third rotary shaft 13, and a lower portion of the second plate 14 has a second polarity different from each other in left and right directions. The permanent magnet 15 and the third permanent magnet 16 is fixedly installed.

In addition, a circular protrusion 17 having a center axis coinciding with the third rotation shaft 13 is fixedly installed on the upper portion of the second plate 14, and a bidirectional spring 18 is wound around the circular protrusion 17. One end of the bidirectional spring 18 is fixed to the rear of the first plate 10 and is hung on the outer surface of the first pillar 19 extending upward, and the other side is fixed to the rear of the second plate 14. It is installed and hung on the outer surface of the second pillar 20 extending upward.

And, in front of the second plate 14, the upper lip member 21, to which the upper lip of the perikan is attached, is rotatably coupled to the second rotation shaft 26 fixed to both sides of the head 3, A first permanent magnet 23 is fixedly installed on the upper lip member 21 above the first coil 11. 1 and 2, the lower lip member 5 is fixed to the head 3, and only the upper lip member 21 is rotated up and down to open and close the mouth of the perican.

1 and 2 are not shown with the face portion cut away for the purpose of explanation, as shown in the side views of FIGS. 4 and 5, the face portion has an opening limiting the range in which the upper lip member 21 moves up and down. An upper lip member 21 rotates only within the range of the upper and lower locking jaws 28 and 29 of the opening 27.

In addition, support structures 24 and 25 are fixedly installed on both upper and lower ends of the second plate 14, and second rotation shafts 26 are fixed to both sides of the head 3 at upper ends of the support structures 24 and 25. ) Exists.

And, as shown in Fig. 4, there is a stopper 30 supporting the second plate 14 so that the head 3 does not fall down.

Now, with reference to Figs. 1 to 7 how to open and close the upper lip member 21, and rotate the head 3 up and down / left and right in the operating toy of the present invention having a structure as shown in Figs. This will be described.

1 and 4 are perspective and side views showing that the upper lip member 21 is closed by lowering the mouth, and FIGS. 2 and 5 are perspective and side views showing a state where the upper lip member 21 is only opened by opening the upper lip member 21 upward. 3 and 6 are a perspective view and a side view of the upper lip member 21 in a state where the head 3 is rotated to the rear as far as possible in the open state. 7 is a graph showing the vertical rotation angle of the upper lip member 21 and the head 3 according to the magnitude of the current applied to the first coil 11.

First, FIG. 7 illustrating the up and down rotation angles of the lips and the head according to the current applied to the first coil 11 in the operating toy of the present invention will be described.

Since the load of the upper lip member 21 and the lips coupled thereto is smaller than the load of the entire head 3 portion, as shown in FIG. 7, the first axis of rotation of the load of the upper lip member 21 and the lips coupled thereto, as shown in FIG. The rotational force Fm with respect to 22 is small compared with the rotational force Fh with respect to the 2nd rotation axis 26 of the load of the whole head 3 part.

In addition, as shown in FIG. 7, the current applied to the first coil 11 in order to overcome the rotational force Fm and move the upper lip member 21 upwards must be equal to or greater than I1, and overcome the rotational force Fh. The current applied to the first coil 11 to rotate the head 3 upwards must be at least I3.

When the coil and the permanent magnet face each other to form a reaction force, the repulsive force is proportional to the applied current and inversely proportional to the distance between the coil and the permanent magnet, so that the permanent magnet attachment member has a rotational force (Fm or Fh) according to the load. ) And the permanent magnet attachment member stops rotation at the angle at which the repulsive force is balanced (the angle of the intersection point of the curve and Fm / Fh with each coil applied current (a1, a2, b1, b2, b3, b4) in FIG. 7). Done.

Now, in view of the above points, the method of rotating the upper lip member 21 and the head 3 in the operating toy of the present invention will be described in detail (see Figs. 4-7).

First, when the current forming the repulsive force to the first coil 11 is applied to I1 or less, the repulsive force is less than the rotation force Fm, so that the upper lip member 21 does not open at all (FIG. 4 state), and starts to exceed I1. When the upper lip member 21 starts to rotate upwardly about the first rotational axis 22, and reaches I2, the upper lip member 21 is rotated by the angle a1 where the rotational force Fm and the repulsive force are balanced. The upper lip member 21 is rotated and opened, and when I3 is reached, the upper lip member 21 is rotated and opened by a balancing angle a2.

At this time, as shown in Figure 5, because there is a locking jaw 28 to prevent the upper lip member 21 from rising anymore, the upper lip member 21 is no longer rotated because of the locking jaw 28 no longer. Can't open On the other hand, the locking jaw 29 is a locking jaw to suppress the falling of the upper lip member 21.

Next, when the current forming the repulsive force in the first coil 11 starts to exceed I3, the repulsive force is greater than the rotational force Fh of the head 3, so that the larger repulsive force in the state of FIG. The upper lip member (21) hanging on the) acts as a force to push up further, to push up the first rotary shaft 22 to which the upper lip member 21 is coupled, eventually connected to both ends of the first rotary shaft (22) The head 3 starts to rotate upwardly about the second axis of rotation 26, and the stopper 30 that was supporting the second plate 14 starts to be spaced apart from the second plate 14.

Then, at I4, the upper part rotates upward by an angle b1 where the rotational force Fh and the reaction force of the head 3 are balanced, and in this way, if the current is increased, the head 3 has an equilibrium angle ( b2), the angle b3 and the angle b4 are rotated upwards by this angle, and the stopper 30 is completely separated from the second plate 14 (see FIG. 6).

In this case, as shown in FIG. 6, since the locking jaw 31 of the opening 4 contacts the neck member 2, the head 3 can no longer rotate upwards.

As a result, the repulsive force according to the current applied to the first coil 11 is equal to or greater than the rotational force Fm according to the upper lip member 21 and less than or equal to the rotational force Fh according to the head 3 (between currents I1 to I3). While adjusting the applied current while adjusting the applied current, the angle of opening of the lip member 21 can be adjusted, and when the applied current is adjusted while the repulsive force according to the applied current is equal to or greater than the rotational force Fh (current I3 or higher) according to the head 3 The vertical rotation angle of the head 3 can be adjusted.

Next, a method of turning the head 3 to the left and right will be described with reference to FIGS. 8-11. FIG. 8 is an internal structural view seen from above when the head 3 is facing the front, FIG. 9 is an internal structural view viewed from above when the head 3 is rotated clockwise (right). FIG. Fig. 11 is a diagram showing an internal structure viewed from the top when 3) is rotated counterclockwise (left turn), and Fig. 11 is a graph showing left and right rotation angles with respect to the second coil applied current.

First, since the second coil 12 is not polarized unless a current is applied to the second coil 12, at this time, as shown in FIG. 8, both leg portions of the spring 18 are formed of the first pillar 19 and the first pillar. Since it hangs on the two pillars 20, the state which looks at the front like FIG. 8 is maintained.

Now, when the current is applied to the second coil 12 so that the S pole is formed in the second coil 12, the S pole formed by the second coil 12 and the N pole of the permanent magnet 15 are formed. A suction force is formed, and a repulsion force is formed between the S pole formed by the second coil 12 and the S pole of the permanent magnet 16, so that the second plate 14 overcomes the resilience of the spring 18. And rotate clockwise about the third rotary shaft 13, and as shown in FIG. 11, the clockwise direction of the second plate 14 by the repulsive force of the spring 18 and the applied current of the second coil 12. The rotation is stopped at the point where the rotational force is balanced, and the state is as shown in FIG. At this time, the rotation angle in the clockwise direction is proportional to the magnitude of the current applied to the second coil 12 as shown in FIG.

In the same manner, when the N pole is formed in the second coil 12 by applying a current in the opposite direction to the second coil 12, the N pole and the permanent magnet formed by the second coil 12 are formed. A repulsive force is formed between the N poles of (15), and a suction force is formed between the N pole formed by the second coil 12 and the S pole of the permanent magnet 16, so that the second plate 14 is a spring. Overcoming the resilience of the (18) and starts to rotate counterclockwise around the third rotation axis 13, as shown in Figure 11 due to the repulsive force of the spring 18 and the applied current of the second coil 12 The rotation stops at the point where the counterclockwise rotational force of the second plate 14 is balanced, and the state becomes as shown in FIG. 10. At this time, the angle rotated in the counterclockwise direction is proportional to the magnitude of the current applied to the second coil 12 as shown in FIG.

As described above, if the magnitude and direction of the current applied to the second coil 12 are controlled, the head 3 can be rotated by a desired angle in a desired direction.

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.

For example, in the above embodiment, as shown in FIGS. 1 and 2, the first coil 11 and the second coil 12 are installed on the first plate 10, and the first coil 11 is disposed on the first coil 11. The permanent magnet 23 is present, and the structure in which the second permanent magnet 15 and the third permanent magnet 16 are installed below the second plate 14 will be described. The first coil 11 and the second coil 12 are fixed to the first plate 10, so that the first coil 11 and the second coil (from the control circuit (not shown) built in the body 1 are not provided). The coil wires (not shown) for supplying current to 12 are fixed to prevent the coil wires from being disconnected by repeating the process of bending and extending the coil wires according to the up / down / left / right rotation of the head 3. The case where it was possible was demonstrated.

However, if there is a preventive measure for coil wire disconnection due to repetitive refraction such as embedding the coil wire in the protection guide that prevents the coil wire from disconnecting from the body 1, the position of the corresponding coil and the permanent magnet may be adjusted. The same effect can be achieved by changing and installing.

1 and 2, when the control circuit is installed inside the head 3 rather than inside the body 1, the control circuit is fixedly installed on the first plate 10, thereby providing the first plate 10. By the first coil 11, the second coil 12, and the control circuit fixedly installed at the coil, it is preferable that the coil wire be refracted despite the up / down / left / right rotation of the head 3.

In addition, in the above description, only the upper lip member 21 is rotated upward, but in order to enable the lower lip to be rotatable, the lower lip may also be installed in the same structure as the upper lip member 21.

In the above description, the structure in which the first rotation shaft 22 and the second rotation shaft 26 are separately installed has been described. However, as shown in FIG. 12, the upper lip member is disposed on the second rotation shaft 26 on the supporting structures 24 and 25. A structure for attaching 21 is also possible.

Further, in the above, the bidirectional spring 18 causes the head 3 to face in the normal state (when the power is not applied), and applies a current to the second coil 12 so that the second coil 12 and Left and right rotation of the second and third permanent magnets 15 and 16 at the point where the left / right rotational force by the repulsive force / suction input of the second and third permanent magnets 15 and 16 balances with the resilience of the bidirectional spring 18. The role of the centering member to stop the operation, but this role is also possible with the usual spring or rubber band connected between the first pillar 19 and the second pillar 20, installed on the first pillar (19) side The centering magnet (the repulsive force and the suction force of the second and third permanent magnets 15 and 16 are balanced) is also possible.
