【Example】

 FIG. 1 shows a remote-controlled automobile toy according to the embodiment. This remote-controlled automobile toy 1 is composed of a controller 2 and an automobile toy 3. Of these, a charging circuit is incorporated in the controller 2 in addition to a transmission circuit for transmitting a control signal, and as shown in FIG. 2, a forward button S1 also serving as a charging button and a turn button also serving as a charging button. S2, a charging lamp LED 5, a transmission lamp LED 6, and a charging connector (controller-side connector) 4 are attached. On the other hand, the car toy 3 is equipped with a rechargeable battery and a receiver for receiving a control signal, and as shown in FIG. 3, a charging connector (car toy side connector) 5 connected to the battery. And a power switch 7 is attached.

Here, the transmission circuit and the charging circuit incorporated in the controller 2 will be described with reference to FIG.

Of these, first, the transmission circuit will be described. Q2, Q3, R6, R4, R5, R1, R2, C8 and C7 form an astable multivibrator. That is, pressing switch S2 produces a square wave pulse having an oscillation frequency determined by R6, R4 and C7 and R6, R5 and C8. When the switch S1 is pressed, a square wave pulse having an oscillation frequency determined by R4 and C7 and R5 and C8 is generated. The collector of Q3 is connected to the emitter of Q1 via R8 to switch Q1.

Q1, C1, C2, and L2 constitute a Hartley oscillator, and a predetermined signal is output from Q1 by switching by this oscillator and the output of the multivibrator. That is, the carrier oscillated in Q1 is repeatedly output at different cycles depending on whether the forward button S1 is pressed or the turn button S2 is pressed.

C3, C4, and L1 connected to the output side of Q1 form an antenna matching circuit that matches the antenna ANT and Q1. That is, it plays a role of canceling the imaginary component (reactance) of the impedance of the antenna ANT and Q1 and effectively sending the output of Q1 to the antenna ANT.

C5 is a bypass capacitor, and R9 and C5 form a decoupling circuit. Further, in this transmission circuit, when any one of the forward button S1 and the turn button S2 is pressed, the transmission lamp D6 indicating that the transmission is in progress is turned on.

Next, the charging circuit will be described. In this charging circuit, when either the forward button S1 or the turn button S2 is pressed, the voltage (+ 6V) is subdivided by R15 and C6, the pulse voltage is applied to the base of Q4 via D4, and Q4 is instantaneously changed. Turn it on. As a result, the base current of Q5 flows through the emitter and base of Q5 and R11, so that Q5 is turned on.

At the same time, the emitter current of Q5 flows into the base of Q6 via R14. This turns on Q6. Therefore, if the car side battery is connected to the controller side connector 4 via the car toy side connector 5, a current of + 6V will flow into Q6 via the car side battery, so that the car side battery will be the time constant. It will be charged quickly.

Even when the transmission switches S1 and S2 are not pressed, the vehicle battery is trickle-charged via R17.

Then, when the time of the time constant has passed, C9 is almost fully charged and the base current of Q4 stops flowing, so Q4 turns off and at the same time the base current of Q5 stops flowing, so Q5 becomes It is turned off, and the base current of Q6 due to the emitter current of Q5 disappears.

On the other hand, the discharge of C9 is started. That is, C9 (+), R13, R16, D3, and C9 (-) are discharged along with C9 (+), R14, Q6 (base), Q6 (emitter), D3, C9 (-). Since it is discharged through the path of Q6, Q6 maintains the ON state, and rapid charging is continued. When the discharge ends, the quick charge ends.

Therefore, the vehicle side battery is charged for a total time of the charging time and the discharging time of C9. The charging lamp D5 is lit only during the charging time of C9.

Next, the controller side connector 4 and the automobile toy side connector 5 will be described. The controller side connector 4 and the automobile toy side connector 5 are plug-in type connectors. Engaging projections 8 are provided on both sides of the controller-side connector 4 as shown in FIG. On the other hand, as shown in FIG. 3, a recess 9 for receiving the charging connector 4 of the controller 2 is provided below the automobile toy 3. A charging connector 5 to be inserted into the charging connector 4 of the controller 2 is provided in the recess 9. Further, engaging pieces 10 are provided on both sides of the charging connector 5, respectively. The engaging piece 10 has elasticity, and the engaging piece 10 is provided with an engaging hole 10a for receiving the engaging projection 8. When the charging connector 4 of the car toy 3 is to be fitted into the recess 9 of the controller 2, the engaging projections 10 on both sides of the charging connector 4 first open the engaging piece 10. When the controller 2 is further pressed against the automobile toy 3, the engaging projection 10 of the controller 2 is engaged with the engaging hole 10a of the automobile toy 3 by the restoring force of the engaging piece 10. In this state, the charging connectors 4 and 5 are engaged with each other. On the other hand, when trying to pull out the charging connector 4 of the automobile toy 3 from the concave portion 9 of the controller 2, the engaging pieces 10 are first opened by the action of the engaging protrusions 8 on both sides of the charging connector 4, and When the controller 2 is separated from the automobile toy 3, the engaging protrusion 8 of the controller 2 is completely disengaged from the engaging hole 10a of the automobile toy 3.

Next, a method of using the remote-controlled automobile toy 1 will be described.

The lower power switch 7 of the automobile toy 3 is turned off, and the lower charging connector 5 of the automobile toy 3 and the charging connector 4 of the controller 2 are pressed. Then, as shown in FIG. 5, the engagement protrusion 8 of the controller 2 is engaged with the engagement hole 10 a of the automobile toy 3. In this state, the charging connectors 4 and 5 are engaged with each other. Therefore, simply pressing the forward button S1 or the turn button S2 of the controller 2 charges the battery mounted on the automobile toy 3.

When the charging of the battery is completed in this way, the power switch 7 on the lower side of the automobile toy 3 is turned on. When the forward button S1 of the controller 2 is pressed, the toy car 3 travels forward.

On the other hand, when the turn button S2 is lightly tapped and pushed, the car toy 3 turns rightward on the spot. Further, if the turn button S2 is continuously pressed, the car toy 3 starts to turn right on the spot.

According to the remote-controlled automobile toy 1 configured as described above, the following effects can be obtained.

That is, when the controller-side connector 4 and the automobile toy-side connector 5 are brought into contact with each other, the engaging projection 8 and the engaging hole 10a are elastically engaged with each other, so that the controller-side connector is charged during charging. Since it is not necessary to press the 4 and the toy side connector 5 against each other by hand, charging can be performed very easily.

Although the embodiment made by the present inventor has been described above, the present invention is not limited to this embodiment, and various modifications can be made without departing from the scope of the invention.

For example, in the above-described embodiment, the engaging projection 8 is provided on the controller 2 and the engaging hole 10a is provided on the vehicle toy 3. However, conversely, the engaging hole is provided on the controller and the engaging projection is provided on the automobile toy. It may be provided in.

Further, in the above-described embodiment, the engaging piece 10 in which the engaging hole 10a is formed is made to have elasticity. However, the engaging projections may be made to have elasticity, or both may be made to have elasticity. Of course, it is also good.

Furthermore, in the above-mentioned embodiment, the plug-in type connectors 4 and 5 are shown, but it goes without saying that the present invention can be applied to other types of connectors.
