Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an actuation device for a driven mechanism such as a steering device of a remote or radio-controlled traveling toy.

BACKGROUND OF THE INVENTION In a conventional steering device for a traveling toy of this type, an electromagnet serving as an operating source and a permanent magnet are disposed opposite each other on a vehicle chassis, and the movable portion thereof is provided to operate a steering wheel. Also,
The steering device is not equipped with an adjustment device. They are also popular as remote-controlled or radio-controlled toy cars that operate according to the driver's wishes, and a variety of toy cars are available, including passenger cars, sports cars, and trucks, which correspond to real cars.

Problems to be Solved by the Invention Since the electromagnet, which serves as the operating source, and the permanent magnet are installed oppositely on the vehicle chassis, they are subject to the infiltration of dust kicked up by the wheels during driving, which directly adheres to the steering device. It may cause malfunction. Also electromagnets, permanent magnets,
In addition, there are some vehicles that deviate from subtle variations in the components of the steering system, causing them to turn slowly to the left or right and not be able to travel straight. It is still necessary to manufacture steering devices suitable for each of the various vehicle models, which has the drawback of increasing costs.

A means to solve the problem is to install a pivot vertically near one side wall of a casing having the required storage capacity, to pivot a steering lever so as to be able to rotate horizontally, and to attach a magnet to one inner end of the pivot. is arranged inside the opposite wall, and both ends of the magnetic core of the electromagnet housed in the casing and facing the opposite inner wall are opposed to each other with an appropriate interval, and the magnetic force of the magnet causes the magnetic pole core of the electromagnet to Fully towed on both ends,
In addition to returning the steering rod to the neutral position, the steering rod is rotated to the left or right around the pivot due to the mutual magnetic force between the magnet and the electromagnet, and this rotational force is transmitted to the outside of the casing, thereby steering the front wheels of the traveling toy. The present invention relates to an operating device for a driven mechanism such as a front wheel steering device of a running toy, which is characterized in that it is related to the driven mechanism.

EXAMPLE Below, this invention will be explained using drawings.

A groove 14 is provided in the center of the trailing edge. The steering rod 16 is equipped with a pin 15 at the front end that engages with the engagement groove 14 of the tie rod 11, and the steering rod 16 is pivoted at the middle on a pivot shaft 18 provided inwardly toward the front of the casing body 17, and at the rear end. The magnet 20 that integrally has the support surface portion 19 and is housed therein is
Electromagnet 2 also housed in unit casing body 17
The magnetic poles 22t (22t) protruding in parallel to the left and right on the rear side of the magnetic pole 1 are disposed opposite to each other with a slight gap therebetween.

The pivot 18 is vertically supported by a support plate 23, and the support plate is loosely fitted into guide grooves 24, 24 which are provided on the inner surface of the front side wall of the casing body 17 inwardly to the left and right. The related shaft portion 25 provided at the lower edge of the support plate 23 is slidable to the casing body 17.

7, and a knob 30 is formed at the rear end of the adjuster below and externally from the bottom G hole 29 of the casing body 17.

When this knob 30 is rotated to the left when viewed from the top, the pivot 41
11.8 moves to the opposite right, and the magnet 20 at the rear end of the steering rod 16 tries to maintain the shortest position by magnetically pulling the magnetic pole 22 of the electromagnet 21. Therefore, the steering rod 16 moves to the opposite right. Rotate around the center, swing the tip to the right, and attach tie rod 11.
can be moved to the right to adjust the front wheels 1, 1 to the right.

At the upper end of the casing body 17 is a lid plate 31 that closes the inside.
A mounting piece 32 is integrally formed on the rear edge of the lower part of the vehicle and projects rearward. The unit casing body 1 is inserted through the attachment hole 35, and the tip is screwed into the bottom attachment hole 36 of the casing body 17.
7 is an iron core attached to the chassis plate 4, and 37 is an iron core whose both ends constitute the magnetic poles 22a and 22b. Reference numeral 38 denotes a disk-shaped operation panel, which is fixed to the pivot portion of the steering rod 16, connects the connecting rod 40 to a connecting hole 39 provided around it, and energizes the electromagnet 21 to operate the required driven mechanism on the chassis plate 4. .

Since the embodiment of the present invention is configured as described above, as shown in the operation explanatory diagram of FIG. 6, when the electromagnet 21 is not energized, the magnet 20 of the steering rod 16 is Due to the action, the magnetic pole 22a of the electromagnet 2]
22b (both ends of the iron core) to rotate the magnet 20 to the extreme distance and hold it in the dry position. The steering rod 16 then returns to its home position and maintains that position. Next, although not shown, when a remote controller or radio control applies a DC voltage as + to the feeder line a of the coil of the electromagnet 21 and as a - to the feeder line a, the magnetic pole 22 of the electromagnet 21
A magnetic force is generated with the N pole at a and the S pole at the magnetic pole 22 b.The N poles of the magnet 20 repel each other, and the N and S poles attract each other, so the magnet 20 moves to the left. Move steering rod 16
Rotate. The pin 15 of the steering rod 16 then moves the tie rod 11 to the left and rotates the front wheel 1.1 to the left.

Therefore, the vehicle turns to the left. Next, when a DC voltage is applied to the power supply lines a and b with the opposite polarity, the electromagnet 21
The magnetic pole 22a becomes an S pole and the magnetic pole 22b becomes an N pole, and a magnetic force is generated opposite to the N pole of the magnet 20, rotating the steering rod 16 to the left. Therefore, the front wheel 1.1 is turned to the left. When the electromagnet 21 is de-energized, the magnet 2
Due to the magnetic force of 0 = :L-) it returns to the normal position and returns to running in a straight line. Here, when the pivot 18 shifts to the left or right and the neutral position shifts to one side, the adjuster 27 is adjusted by operating the knob 30.

Effects of the Invention As described above, the device of this invention has a pivot at one end of the casing near the front, one half protrudes outward, the other half is housed inside the casing, and the housing part Since the steering rod, in which the magnet supported at the end faces the magnetic pole of the electromagnet housed in the casing with a small gap, is pivoted to the pivot, these are mounted on the chassis plate as an operating unit, and the steering rod is mounted on the chassis plate as an operating unit. It can be connected simply by engaging with the tie rod of the steering device, and can, for example, change the running direction of the front wheels to the left or right for steering.

However, since the corresponding parts of the electromagnet and the steering rod are housed within the casing, there is no dust that enters during driving, compared to the conventional case where they are placed bare on the chassis plate. Therefore, the steering operation can be performed smoothly.

However, especially in models where the pivot can be moved from the outside to the left and right to adjust the support position of the steering rod, it is possible to energize the electromagnet and adjust the neutral position of the steering rod when not in left-right turning operation by excitation operation. However, biasing effects caused by variations in magnets, electromagnets, and other components can be eliminated, and the vehicle can run straight.

In addition, since the steering rod and electromagnet are set in the casing and made into a unit, the steering feather device can be standardized and installed in the same type even in different car models such as passenger cars, sports cars, and trucks, which contributes to reducing manufacturing costs. It is possible.

Further, the output portion of the steering rod can be made into a disk shape with connecting holes arranged around the periphery, and the connecting rods can be connected and used like a servo motor.
