It is arranged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a traveling toy including a power device that can be remotely controlled.

[0002]

[Prior Art]

 Conventionally, a traveling toy equipped with a power unit has been configured with a remote unit for controlling a power unit by wireless control and a remote unit for operating a steering unit.

[0003]

[Problems to be solved by the device]

 However, according to the conventional running toy described above, since the remote device for controlling the power unit and the remote unit for operating the steering unit are formed separately, the control unit becomes complicated, and the control method by radio control also has a number of channels. However, there were drawbacks such as increased cost and increased cost.

The present invention has been made in view of the above problems, and it is an object of the present invention to simplify the entire structure by controlling only a power device by a remote device.

[0005]

[Means for Solving the Problems]

 The traveling toy of the present invention has the following requirements. That is, (a) driving wheels are provided at the rear of the chassis and steering wheels having a caster effect are provided at the front. (B) A power unit that can be remotely controlled with respect to the drive wheels is configured.

[0006]

[Action]

 In the above structure, when the drive wheels at the rear of the chassis are driven by the power unit, the chassis is pushed forward, and the steering wheels at the front are oriented by the caster effect to adapt to the direction in which the chassis is pushed out. It is possible to change and drive the vehicle in that direction. Therefore, if the road on which the vehicle is to be run is curved and tilted corresponding to the curve, the force of the vehicle body in the direction of descending the slope of the road and the slope of the slope due to the centrifugal force accompanying the running The chassis can be oriented in a direction in which the outward force is balanced, and the vehicle body can be driven in the required direction depending on the chassis direction and steering wheel direction at that time. That is, if the driving speed of the driving wheels is maintained at a high speed, the straightness of the vehicle can be improved, and the vehicle can be driven along the outside of the sloped curved road surface. The straightness is weakened, and the weight of the vehicle overcomes the force of descending the slope, allowing the vehicle to travel along the inside of a curved road surface.

The present invention will be described below with reference to an embodiment shown in the drawings. In FIG. 1, reference numeral 1 is a chassis of a running toy. Bearings 11 are formed in the parts, and steering wheels 3 each having a caster effect are rotatably supported on the left and right. A motor 4 of a power unit is provided in the front part of the chassis 1, and a power transmission means including a pinion 51, a gear 52, a rotary shaft 53, a pinion 54, a crown gear 55, etc. is provided on the output shaft side of the motor 4. 5 is provided, and its crown gear 55 is provided on the rotary shaft 21 of the drive wheel 2. The power plant is provided with a power source battery (not shown) and a receiving device for remote control. These relatively heavy devices are placed in the front part of the chassis 1 and the center of gravity of the vehicle is set. Are distributed so that they are located near the front steering wheel 3.

FIG. 2 shows another embodiment. In this case, instead of the steering wheels 3, steering wheels 6 also having a caster effect are provided at the front part of the chassis 1. The support shafts 61 of the left and right steering wheels 6 are connected to each other by a connecting shaft 7.

With the above configuration, when the motor 4 rotates and the drive wheels 2 are driven via the power transmission means 5, the chassis 1 is pushed forward and the front steering wheels 3 are caster-effected. The vehicle can be driven in the direction in which the chassis 1 is pushed out depending on the result, and if the center of gravity is located in front of the steered wheels 3 by the weight distribution of the vehicle, straightness Can be raised. On the other hand, if the traveling path A 1 to be traveled as shown in FIG. 3 constitutes an appropriate curved portion A1 and as shown in FIG. In the figure, the component force F1 of the gravity F1 of the vehicle body B in the vertical direction of the traveling path A, that is, the component force F2 in the horizontal direction, that is, the force f2 in the direction of descending the slope, and the force F toward the outside of the slope due to the centrifugal force accompanying traveling are balanced. The chassis 1 can be turned in the direction that the vehicle moves, and the vehicle body can be driven in a desired direction depending on the direction of the chassis 1 and the direction of the steered wheels 3 at that time. That is, if the traveling speed is maintained at a high speed by the driving force of the drive wheels 2, the force F toward the outside of the slope wins, the vehicle can travel along the outside of the sloped curved road surface, and the traveling speed becomes low. Then, the force f2 of descending the slope due to the weight of the vehicle prevails, and the vehicle can travel along the inside of the curved road surface. Therefore, the direction of the chassis 1 is controlled by the driving force applied to the drive wheels 3, and the steering control of the vehicle can be indirectly performed by remote operation of the power unit that controls the driving force.

[0010]

[Effect of the device]

 As described above, according to the traveling toy of the present invention, since the steering control of the vehicle can be indirectly performed by the remote control of the power unit, for example, the power unit only needs to turn on the motor to change the inertia of the traveling vehicle. It is possible to use speed control, and the distance control device for controlling this can be the simplest one channel, the number of parts can be reduced, the structure can be simplified, and the manufacturing cost can be greatly reduced.
