Description

[Detailed description of the invention] This invention relates to a radio-controlled toy car that allows you to enjoy two different driving conditions.

The purpose of this invention was to provide a toy car that can perform symmetrical driving changes, such as the high-speed feeling of driving at high speed on a highway and the dynamic feeling of driving over an uneven road surface at low speed.

Below, this invention will be explained with reference to drawings as an embodiment. 1 is a radio-controlled toy car main body that is equipped with a power source battery 2 and can run independently, and a two-channel receiver 3 transmits data from a different location (not shown). It is provided so that it receives a control signal from the device and outputs it to two left and right drive motors 4 and 5, so that simultaneous rotation of the motors causes forward and backward movement, and one rotation causes left and right turning movement.

Further, external output terminals 6 and 7 are provided on the bottom surface of the rear part, and these output terminals 6 and 7 are connected to a center terminal 8 and a spring 9.
The spring 9a and the terminal piece 9b are connected to each other, and when a plug described later is connected, the connection between the spring 9a and the terminal piece 9b is released. A specific example of the connection between the receiver 3 and the left and right drive motors 4 and 5 is as shown in FIG. 9b and the spring piece 9a, and the right terminal 11 of the receiver 3 is also connected to the terminal piece 9b of the external output terminal 7.
The terminals 12 on the other side of the receiver 3 are connected to the other terminals of the left and right drive motors 4 and 5, respectively, and the external output terminals 6 and 7 are connected to each other via the spring pieces 9a.
It is connected to the center terminal shafts 8, 8 of.

The left drive motor 4 rotates the left front wheel 14, and the right drive motor 5 rotates the right front wheel 15.

When the receiver 3 operates its forward and backward movement sticks forward in accordance with a transmitter (not shown), the same voltage is supplied to the left and right drive motors 4 and 5, which are operated simultaneously to move the motors forward in a rectangular direction. Next, when the stake is switched to reverse, the left and right drive motors 4 and 5 are reversed depending on the polarity of the power supply, causing the vehicle to travel backward in a rectangular direction. Next, to make left and right turns, although not shown in the figure, by operating the forward/reverse stay of the transmitter to move forward or backward, and then operate the turning stay placed next to it, for example to the left, the signal of the transmitter will be activated. In response, the receiver 3 directly supplies power to the right terminal 11 to rotate the right drive motor 5, but the left terminal 1
At 0, the output is zero, so the left drive motor 4 stops rotating. Therefore, left and right drive motors 4, 5, left and right front wheels 14, 15, and a transmission gear (not shown)
The steering frame 16, which supports the
8 and rotate until it collides with one of the stoppers 19 or 19, and then turns left and moves forward.

In the case of backward turning to the left, the left drive motor 4 operates in reverse and the right drive motor 5 stops, so the movable support frame 16 similarly rotates to the left and turns backward. Reference numeral 20 denotes a running bogie, which has left and right front axles 24, 25 to which left and right front wheels 22, 23 are fixed to both front and rear sides of a bogie frame 21, and left and right rear axles 28, 29 to which left and right rear wheels 26, 27 are fixed, respectively, independently. A terminal gear 3 is rotatably mounted on each axle 24, 25, 28, 29.
0, 31, 32, 33 are attached, one of which is provided in the pinion part 34 that meshes with those gears, and the other is provided in the bevel gear part 35. Intermediate reduction gears 36, 37, 3
8, 39 are connected to the axles 24, 25, 26, 27, respectively.
It is attached to the second transmission shafts 40, 41, 42, 43 opposite to the
The front and rear ends are provided with transmission gears 44, 45, 46, 47 meshing with the first reduction gears 50, 51 and the motor shaft gear 52 on the respective shafts, respectively, with dedicated left drive motor 48 and right drive motor 49. , 53, and the related first transmission shafts 54, 55 are supported on the bogie frame 21 at a distance from each other in the left and right directions.

Reference numerals 56 and 57 designate plugs that protrude from the rear upper surface of the bogie frame 21, and an example of a detailed implementation thereof is shown in FIG. Inner cylinder 58 to be brought into contact
and an outer cylinder 59 that is wrapped around the outer periphery of the outer cylinder through an insulating part.
The toy car main body 1 is fitted to the top surface of the running cart 20, and the external output terminals 6, 7 and plugs 56, 57 are fitted thereinto, and the toy car body 1 is fitted into the engagement recess 60 provided on the top surface of the running cart 20. The front wheels 14 and 15 of the vehicle body 1 are engaged with each other, and the vehicle body 1 is engaged and mounted on a traveling trolley 20 as shown in FIG.

In the traveling bogie 20, the electrical connection between the plugs 56, 57 and the left and right bogie drive motors 48, 49 is as shown in FIG.
and one terminal 48a of the left truck drive motor 48.
However, the outer cylinder 59 and the other terminal 48b are respectively connected. Similarly, in the plug 57, the inner cylinder 58 and one terminal 49a of the right truck drive motor 49 are connected to each other.
Further, the outer cylinder 59 and the other terminal 48b are connected to each other, and the terminals 48b and 49b of the left and left truck drive motors 48 and 49 are connected by the same common electric wire.

Since this embodiment of the invention is constructed as described above, when the radio-controlled toy car body 1 is engaged and mounted on the traveling trolley 20, the left and right drive motors 4 and 5 in the toy car body 1 are moved from the spring piece 9a to the terminal piece 9b. The connections between the toy car body 1 and the toy car main body 1 are disconnected, so that power is no longer supplied to each of them, and the front wheels 14 and 15 of the toy car body 1 stop operating. However, the external output terminals 6 and 7 output power to the left and right truck drive motors 48 and 49 of the traveling truck 20 through plugs 56 and 57 to drive them. Therefore, the left front and rear wheels 22, 26 and the right front and rear wheels 23, 27 are rotated at the same speed via the left and right side reduction transmissions, respectively. Therefore, the traveling trolley 20 moves straight forward. In this running state, if you want to turn to the left, tilt the turning stick of the transmitter (not shown) to the left in the same way as when the toy car body 1 is running alone, and the right truck drive motor 49 will rotate, and the left truck drive motor 48 will rotate. Since it stops, it makes a left turn. The same applies to right turns. However, when switching to reverse, if the turning stick is tilted to the left in order to make a left turn, the left truck drive motor 48 rotates and the right truck drive motor 49 stops, so the vehicle turns to the right. Therefore, only when turning backwards, the left and right turning direction is different from that of the toy car body 1 alone, and the toy car body 1 turns in the opposite direction, so the operation must be reversed. When traveling on the traveling trolley 20, the front, rear, left and right wheels 22, 23, 26,
Since the 27 rotates at the same speed and at a reduced speed, the torque increases and it can climb steep slopes.Also, since the wheels can be made larger in diameter than the wheels of the toy car itself, the vehicle height is high and it can handle uneven roads. It is possible to run.

In the above embodiment, the traveling trolley 20 is a four-wheel drive vehicle, but it may be a six-wheel drive vehicle.

As described above, according to this invention, it is possible to play by freely running the radio-controlled toy car on the road surface at high speed as if it were a general toy car, and by connecting the main body to a separately provided running trolley, which has a simple configuration. As a special all-wheel-drive vehicle equipped with an expensive radio control function, you can experience the real thrill of driving powerfully over steep slopes and unleveled surfaces with large irregularities that are impossible for regular toy cars.

Therefore, two types of radio-controlled toy cars can be enjoyed economically.
