Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a four-wheel drive traveling toy, and in particular, the invention automatically raises the vehicle body to raise the height of the vehicle when overcoming an obstacle while driving. It provides structure.

[Conventional technology]

Conventionally, four-wheel-drive traveling toys are suitable for driving on rough terrain,
The vehicle height was raised in advance to ensure minimum ground clearance.

[Problem that the invention attempts to solve]

However, with the above structure, the vehicle height cannot be changed from a set position, and when driving on flat ground, the vehicle height is too high and has drawbacks such as poor appearance and poor running performance.

[Means for solving problems]

The present invention eliminates the above-mentioned drawbacks by linking a reduction gear device to the output shaft of a drive motor, and connecting an axle with gears that mesh with the final gear of the gear device, with the final gear being centered. This is made up of a movable bearing between the lower part and the rear of the vehicle, which allows the vehicle to automatically levitate and raise the vehicle height when overcoming an obstacle while driving, thereby completing the overcoming of the obstacle. The system is configured to automatically return the vehicle height to its original height.

〔Example〕

The present invention will be explained with reference to an embodiment shown in the figure below. Reference numeral 1 denotes a bearing plate installed in the vehicle body of a traveling toy. A battery box 2 with a switch is provided on the bearing plate 1, and a battery box 2 with a switch is installed below it. A pinion 4 is provided on the output shaft of the motor 3, a spur gear 5 meshes with the pinion 4, a pinion 6 integral with the gear 5, a spur gear 7 meshes with the pinion 6, A pinion 8 that is integral with the spur gear 7, a spur gear 9 that meshes with the pinion 8, a pinion 10 that is integral with the gear 9, and a spur gear 1 that meshes with the pinion 10.
1. A reduction gear device including a pinion 12 integrated with the spur gear 11 is provided, an axle 14 is provided with a spur gear 13 that meshes with the final stage gear of the reduction gear device, that is, the pinion 12, and the axle 14 is provided. is movably supported between the lower side and the rear of the pinion 12 through an arc-shaped elongated hole 15 centered on the pinion 12.

[Effect]

With the above configuration, on a normal flat road, the axle 14 is positioned at the rear as shown in FIG. 3A, and the height of the vehicle body 17 is lowered to allow the vehicle to travel. Next, when the vehicle hits an obstacle while traveling, a load is applied to the front wheels 16 and their rotation is temporarily stopped. Meanwhile, while the reduction gear device continues to rotate due to the rotational force of the motor 3, the axle 14 is moved forward along the elongated hole 15 along with the rotation of the pinion 12, and the bearing plate 1 is relatively moved as shown in FIG. The vehicle height of the floating vehicle body 17 can be automatically raised as shown in FIG. This allows you to climb over obstacles while keeping the vehicle height high. Next, at the stage when the crossing is completed, the vehicle body 17 tilts forward as shown in FIG. By lowering the bearing plate 1 as shown in the figure d, the vehicle height of the vehicle body 17 is automatically lowered, and the vehicle returns to the normal running condition on a flat road and can continue traveling.

[Effect of idea]

As is clear from the above explanation, when driving on a normal flat road, the vehicle height is lowered, and if it hits an obstacle while driving, the vehicle height is automatically raised to overcome it. It can be adapted to run on rough terrain. Next, when the vehicle overcomes an obstacle and returns to a flat road, the height of the vehicle can be automatically lowered and the vehicle can be driven, improving both the design and the driving performance. Note that the vehicle height can be relatively changed by h by moving the axle 14, but the means for moving the axle 14 is not limited to the elongated hole 15, but may be constructed of a swingable bearing plate. You can also.
