Description

[Detailed description of the invention] [Industrial application field] The invention consists of a power unit with a built-in power source, motor, etc. and a receiving mechanism, a steering mechanism, and an upper outer shell of a traveling vehicle that can be assembled into a chassis. Regarding radio-controlled toys.

[Prior Art] Conventionally, radio-controlled toys have been highly entertaining toys, and enthusiasts of relatively older age groups have enjoyed radio-controlled toys by mounting an engine on a car body that they have manufactured themselves.
At this time, the engine or motor for driving the car, a steering mechanism, and a servo motor are built into the car body, a receiver is mounted, and the upper outer shell of the car body is attached. Therefore, the play element of creating one's own products based on one's own preferences accounted for a high proportion of the overall play value.

[Problem to be solved by the invention] If the above-mentioned conventional technology's "assembly-type car body" is adopted for a toy aimed at a relatively young age, the child will not be able to fully enjoy the play because the assembly work is not easy. It contains the following problems. Therefore, the present invention houses the drive mechanism part, which is difficult to assemble, in a single power unit, and allows the steering mechanism and other parts that operate in conjunction with this power unit to be assembled freely, and connects each of the above parts. It is designed so that it can be fitted using a restraining member having a retaining claw.

[Means for Solving the Problems] The present invention was made to solve the problems in the conventional technology described above, and the power unit has a built-in power source, a motor for the traveling toy, and a motor for operating the steering mechanism. The casing of the power unit is provided with two output gears that are individually linked to the two motors, and each member constituting the traveling mechanism is connected to the front axle to drive the chassis. The power unit and each member of the steering mechanism are installed in the front part so as to be freely assembled, and each member of the power unit and the steering mechanism is fitted into the chassis by a restraining member formed with a protruding piece having a locking claw at the tip. The steering mechanism and rear wheels are linked to two output gears protruding from the power unit, and the upper outer shell of the traveling vehicle is formed to be removably attached to the chassis.

[Function] A steering mechanism is assembled at the front of the chassis, a power unit with a built-in drive mechanism and a receiving mechanism is mounted on the chassis, and each of the above members is attached to a restraining member having a protrusion with a locking claw at the tip. It is then fitted onto the chassis. Then, the transmission gear of the rear axle is assembled so as to mesh with the output gear for traveling drive of the power unit, and the upper outer shell of the traveling vehicle is attached to the chassis.

[Example] An example of the present invention will be described with reference to the drawings.

A motor 7 is fixedly installed in the casing adjacent to the battery storage portion to operate a steering mechanism to be described later. A motor pinion 8 of the motor 7 meshes with a gear 10 that is mounted on a gear shaft 9, and a pinion 11 provided coaxially with the gear 10 meshes with a crown gear 12. A gear shaft 13 on which the crown gear 12 is mounted projects downwardly from a through hole 14 in the lower housing 5a of the power unit 5, and an output gear 15 is mounted on the lower end of the gear shaft 13. A printed circuit board 16 is fixed to the upper part of the lower casing 5a of the power unit 5, and is equipped with a known receiver for radio-controlled toys. A power switch knob 17 provided on the printed circuit board 16 projects downward from a through hole 5b formed at the bottom of the lower housing 5a. A receiving antenna 25 extending from the printed circuit board 16 projects upward from the upper shell 1.
The printed circuit board 16 and the antenna 25 constitute a receiving mechanism. A traveling drive motor 18 is fixedly installed inside the upper housing 5.
The motor pinion 19 of No. 8 meshes with an output gear 21 which is rotatably mounted on a gear shaft 20. This output gear is composed of three gears: a large gear 21, a middle gear 22, and a small gear 23, and one of these three transmission gears 21, 22, and 23 meshes with a transmission gear on the rear axle, which will be described later. By doing so, it is possible to obtain a running speed that corresponds to the vehicle type.
