Description

[Detailed Description of the Invention] The present invention relates to a traveling toy in which a driving motor is integrally provided in a traveling body.

Conventionally, in a traveling toy in which a driving motor is integrally provided with a traveling body, the motor has been stored and held in a nearly closed storage chamber in order to ensure its retention. However, despite this problem, the temperature of the motor rises during continuous running, which can eventually lead to burnout of the motor due to overheating, and deformation and burnout of the running body such as the chassis and body. No proper cooling measures were taken.

The present invention solves the above-mentioned conventional problems, and has an extremely simple structure that constantly cools the motor while driving to prevent it from overheating, thereby eliminating any negative effects on the motor and its surroundings, and allowing it to operate for long periods of time. The purpose is to enable continuous running.

The present invention is a running toy equipped with a drive motor on the chassis of a running body, characterized in that the brush terminal of the motor is projected to the outside of the chassis so that it can come into contact with the outside air.

An embodiment of the present invention will be described with reference to the drawings. The illustrated example shows a chassis 1 of a traveling toy, which is divided into two parts, an upper chassis body 1a and a lower chassis body 1b formed in a frame shape, and facing each other. It is becoming connected. These upper chassis bodies 1a
The lower chassis main body 1b is partially formed with a motor storage chamber 3 for storing a driving motor 2 formed by combining these parts, and a battery storage chamber 5 for a battery 4 connected to the motor 2. A rear wheel (or front wheel) 6 driven by a motor 2 and a freely rotatable front wheel (or rear wheel) 7 are respectively pivotally supported at both ends of the motor.

Furthermore, the brush terminal 8 of the motor 2 connected to the battery 4 is made to protrude to the outside of the chassis through a hole 9 formed in one or both of the upper chassis body 1a and the lower chassis body 1b to actively draw outside air. It is designed to enhance the contact cooling effect.

In addition, if the brush terminal 8 of the motor 2 is inserted straight into the hole 9 without bending it, it is advantageous because the width of the chassis 1 can be narrowed, and the rotation of the wheel It is convenient because it enables effective cooling by the wind generated by the vehicle and the wind generated when the vehicle is running.

In addition, when the batteries 4 are stored in the chassis 1 at the same time as in this embodiment, there is a through hole 1 in the outer wall of the battery storage chamber 5 through which a part of the stored batteries 4 is exposed.
0 to the upper chassis body 1a and the lower chassis body 1
By providing holes in one or both of b, the battery 4 is also cooled by the outside air while driving, preventing the temperature of the battery 4 from rising, and extending the life of the battery 4. In order to increase the cooling effect of this battery 4,
It is desirable to determine the total opening area of the battery storage chamber 5 so as to expose as much of the battery 4 as possible without impairing the battery holding function of the battery 4 in the battery storage chamber 5.

Although the shape of the opening 10 is not particularly limited, it is preferably rectangular along the shape of the battery 4 as shown in the figure, and the long edge 11 of the opening 10 holds the battery 4. Furthermore, if slits 11a and 11b are formed perpendicularly to the long edge 11 and an elastic force is applied between the slits 11a and 11b, shocks to the battery 4 caused by driving on rough roads or colliding with obstacles can be prevented. It is useful because it absorbs

In the figure, 12 is a connector socket for inserting a charger (not shown) connector from an opening 13 opened on the bottom surface of the lower chassis body 1b when a rechargeable Ni-Cd battery or the like is used as the battery 4. And,
It is connected to the battery 4 by an electric circuit, 14 is a threaded portion of a screw (not shown) for connecting the upper chassis body 1a and the lower chassis body 1b, and 15 is either the upper chassis body 1a or the lower chassis body 1b. 16 is an opening formed in the lower chassis body 1b for protruding the operating end of a switch (not shown) connected to an electric circuit. The opening shown is shown below.

Next, to explain the operation of the present invention, the motor 2
and a battery 4 are connected through an electric circuit and inserted into the motor storage chamber 3 and battery storage chamber 5 of the lower chassis main body 1b, respectively, and the brush terminal 8 provided on the motor 2 is protruded from the hole 9 to the outside of the chassis. While doing so, connect the upper chassis bodies 1a facing each other.
Next, the body (not shown) is locked and the motor 2 is driven while the brush portion of the motor 2 is cooled through the brush terminal 8 by the wind generated by the rotation of the wheels and the running wind. This prevents overheating and allows continuous running for long periods of time.

Furthermore, since the battery 4 is also partially exposed through the opening 10, the battery 4 is also constantly cooled while driving, and when a rechargeable battery such as a nickel-cadmium battery is used as the battery 4, If you touch the exposed part of the battery 4 through the through hole 10 with your finger during charging, abnormal heat generation can be immediately detected, so overcharging can be easily prevented and the life of the battery 4 can be extended.

In the above embodiment, the chassis is divided into two parts, upper and lower, but the direction of division can be horizontal or any other direction depending on the shape of the chassis, and the division can be divided into three or three parts. It is possible to make it larger than that, and in short, it is sufficient that a hole 9 is provided for inserting the brush terminal 8 provided on the motor 2 and bringing it into contact with the outside air, and its position is not limited to the divided part and can be stored. It is preferable to set the shape to match the shape of the motor 2. In addition, in the above embodiment, a chassis that locks the body is described as an example of a running body, but the application is also applicable to a running body where the body and chassis are integrally molded, that is, where the motor 2, battery 4, etc. are directly housed in the body. It is possible.

As described above, according to the present invention, the extremely simple and rational structure allows the motor to be constantly air-cooled while driving, making it possible to run continuously for long periods of time without overheating. , which can further increase interest as a running toy.
