Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 12.

The present invention comprises a driving wheel (10,100) largely coupled to the shaft (12), a driving means for driving the driving wheel, and a cap (80,180) coupled to the side of the driving wheel.

In addition, the present invention vehicle toy 1 may be further provided with a cap driving means for driving the cap (80,180) for supporting the driving wheel in order to enable the driving wheel (10,100) to run in a more stable state when moving forward. .

In any case, whatever the structure of the present invention, the toy of the present invention requires that the overall appearance of the present invention has a perfect sphere shape, and as shown in FIG. It should be painted or covered with leather, and seemingly look almost identical to the shape of a ball for a ball.

Figure 1 is an exploded perspective view showing the separate parts to show the overall configuration of one embodiment of the present invention toy 1, the present invention toy 1 is a penetrating two to the shaft 12 in the center Drive wheels 10 and 100 and gear housings 41, 42, 43, and 44 interpolated into the interpolation grooves 13 of the drive wheel 10 are meshed with each other, and the gear housing 20 is mounted. 20 and a housing cover 30 equipped with a motor 40 and a cap holder 72 for transmitting rotational force to the drive wheel by the gears, and a bolt 90 to the cap holder 72. It is composed of a cap (80,180) fixed by.

In describing the process in which the driving force of the motors 40 and 140 is transmitted to the driving wheels 10 and 100, both structures are the same from the center of the shaft 12, and thus only one part will be described.

That is, the driving wheel 10 receives the rotational force transmitted to the fourth gear 44 that is in contact with the shaft 12, in this case, the hexagonal through hole, that is, the hexagonal through hole 11 is drilled in the center of the drive wheel 10 The hexagonal through hole 11 is fitted with a hexagonal boss formed on one side of the boss of the fourth gear 44, that is, the hexagonal boss 44b.

The fourth gear 44 is meshed with the shaft 41a of the second gear 42 and engaged with a third gear 43 having a deceleration function. Is meshed with the first gear 41, and the first gear 41 is fixed to the shaft of the motor 40, so that when the motor 40 mounted on the housing cover 30 rotates, The driving wheel 10 also rotates in the same direction as the rotation direction.

A spiral portion 12a is formed at the end of the shaft 12 so that the gear housing 20, the fourth gear 44, and the housing cover 30 are sequentially inserted into the shaft 12, and then the nut It is coupled by fastening with (34), wherein the shaft 12 is not fixed anywhere.

In addition, the housing cover 30 is formed with a control circuit board for controlling the rotation direction of the drive wheel 10 in response to a signal of a wireless control device not shown, to supply electricity to the control circuit board and the motor 40 The battery 36 is installed.

As such, when the driving wheels 10 and 100 rotate simultaneously in the same direction, the present invention toy 1 moves forward or backward, and for this purpose, the center of gravity of the toy 1 should be located below.

Therefore, in order to lower the center of gravity, it is preferable to install a component having a large weight such as a motor, a circuit board, a battery, and the like under the housing cover 30.

Another embodiment of the present invention is to support the driving wheel in the forward movement of the driving wheel (10,100) by configuring the cap 80, which is fixed to the right side of the housing cover 30 to move backward in the first embodiment described above. It is configured to be.

That is, in another embodiment of the present invention, the configuration of the driving wheels 10 and 100 to the housing cover 30 is the same as that of the first embodiment, but the configuration for driving the caps 80 and 180 to the right of the housing cover 30 is added. Is different.

That is, the wheel cover 50, in which the cap driving unit 70 for driving the caps 80 and 180, is mounted on the housing cover 30, is coupled to the cover fixing unit 31 by the screw 35.

A cap fixing unit 72 is formed in the cap driving unit 70, and caps 80 and 180 are fixedly coupled to the cap fixing unit 72 by bolts 90.

The cap drive unit 70 has a long hole 71 formed therein, and an eighth gear 48 is formed at the bottom of the long hole 71. Gear teeth are not formed at both ends of the eighth gear.

This configuration is necessary for idle rotation, that is, when the seventh gear 47 engaged with the eighth gear 48 is positioned at both ends of the long hole 71. The reason why the idling of the seventh gear 47 is required will be described again below.

Guide portion 52 is formed on the wheel cover 50, and supports the cap drive unit 70 when it is reciprocated. In addition, the cap drive unit 70 is coupled by the washer 54 so as not to be separated from the guide unit 52.

A spring 60 is coupled to the upper end of the guide part 52 and the upper end of the cap drive part 70 so that the elastic force acts between the cap drive part 70 and the guide part 52. The spring 60 is the seventh gear 47 to the eighth gear 48 at the moment when the motor 40 reverses when the seventh gear 47 is idling with the seventh gear 47 positioned at both ends of the long hole 71. This configuration is necessary for easy fitting.

Accordingly, the driving of the caps 80 and 180 is performed as follows.

Caps (10,100) driving initial state, that is, the cap (80,180) of the state before driving the motor (40,140) is located in the center of the driving wheel (10,100), the cap drive unit 70 is fixed to the cap (80,180) wheels It is located inside the cover 50.

At this time, the seventh gear 47 is in a state where it is located at the left end of the long hole 71, that is, the portion where the gear teeth are not formed.

The sixth gear 46 is meshed with the fifth gear 45 which is affixed to the shaft 42a of the second gear 42 penetrating the housing cover 30, and the fifth gear 45 is the second gear. The driving force of the motor 40 is received through the 42.

Therefore, the driving direction of the motors 40 and 140 is controlled by a wireless control device to drive the vehicle toy 1 while the power of the vehicle toy 1 of the present invention is turned on.

When the signal of the radio control apparatus is transmitted to the control circuit board, power is supplied to the motors 40 and 140 to be started. In this case, when both motors 40 and 140 are rotated in the forward direction, the motors 40 and 140 are gears 41 connected to the motor. And 42, 43 rotate the fourth gear 44, and the fourth gear 44 rotates the driving wheels 10 and 100 coupled to the hexagonal boss 4a in the same direction as the rotation direction of the motor. Is to be made.

Therefore, the present invention automobile toy 1 is advanced in the future.

Of course, if both of the motors 40 and 140 are rotated in reverse, the driving wheels 10 and 100 will be reversed. If one motor 40 is rotated forward and the other motor 140 is rotated in reverse, the present invention toy 1 Will rotate in place.

Of course, the rotation in the opposite direction is possible, and if one motor is stopped and only the other motor is rotated, the direction can be changed.

If the caps 80 and 180 are formed on the side surfaces of the driving wheels 10 and 100, when the motors 40 and 140 are rotated in the forward direction, the rotational force of the second gear 42 may be rotated simultaneously with the forward movement of the driving wheels 10 and 100. Since the eighth gear 48 in the state of being pulled by the spring force of the spring 60 is engaged with the seventh gear 47, the rotational force of the fifth gear 45 is transferred to the eighth gear 48. This will push the cap driving unit 70 backward so that the cap (80,180) is moved to the rear to support the driving wheel (10,100) to move forward as shown in FIG. .

When the cap 80 is completely pushed back, the seventh gear 47 is positioned at the end of the long hole 71 of the cap driving unit 70 without a gear tooth, and thus the driving force of the motor 40 is driven. Only the wheel 10 is transmitted.

At this time, the cap drive unit 70 is also in a state of receiving a resilience force by the spring 60 is changed to the opposite side.

On the contrary, when the motors 40 and 140 in each of the driving wheels 10 and 100 are rotated in the reverse direction by the radio steering apparatus, the gears connected to the motors are all rotated in the reverse direction. The fifth gear is reversely rotated by the gear, which causes the eighth gear 48 to be pulled while being engaged with the seventh gear while being pulled by the spring force of the spring 60. 80 is to return to the original position.

As such, when the cap drive unit 70 is completely returned to its original position, the vehicle toy 1 of the present invention is completely spherical again.

Since the center of gravity of the driving wheel is located at the bottom when the vehicle toy 1 of the present invention as described above is movable, but is not supported by the cap, it is difficult to move in the exact direction as in the conventional automobile toy. However, since the present invention toy 1 is formed in the surface of the ball for ball, such as a soccer ball on the surface as shown in Figure 11, it looks like a ball for ball rather than a car, so the ball moves on its own Rather, it may give a different pleasure from the conventional car toy.

The present invention can be selected according to the needs of buyers by having the shape of a soccer ball as well as a ball for basketball, volleyball, golf ball and other ball.

As described above, the present invention looks like a ball because it has the shape of a ball for ball, but when the wheel is driven by a motor, it can be moved back and forth like a car, and can be rotated in place. It is a very useful invention that can attract people's attention, stimulate the desire to buy, and especially give children a totally different fun from the conventional car toys.
