[0004]
[Problems to be solved by the invention]
However, in the configuration of the conventional traveling body, since the traveling body becomes wider than the model body, even if the traveling body is brought close to each other as shown in FIG. However, it was impossible to produce a squeeze (just approaching) that is still an important point in the production of competitive games. Although the motor that greatly affects the width of the traveling body can be somewhat narrowed by making it thinner, the use of a thin motor increases the price of the motor itself, and makes the motor thinner. Then, the performance, particularly the torque, is reduced, and as a result, the running speed of the traveling body is lowered, so that the sense of speed of the race and stable running are sacrificed. Furthermore, since the main plate is arranged outside the traveling body, when exchanging drive wheel tires that are consumables, part of the traveling body has to be disassembled, and maintenance workability is poor. There's a problem.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, the driving device for a traveling body of the present invention is configured such that when the traveling body is viewed from the side, the left and right independent drive motors are arranged so as not to overlap on the mounting plate. Thus, the running body is made thinner by using a conventionally used drive motor without being restricted by the drive motor itself.
[0006]
In addition, the mounting plate for supporting the drive motor and the train wheel is disposed inside both the drive wheels, and the drive motor, the train wheel and the like are attached to both sides of the single mounting plate, thereby The drive wheel is provided on both sides of the mounting plate, and the drive wheel can be easily attached and detached for maintenance.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
A driving device for a traveling body according to the present invention is a driving device for a traveling body that can travel on a traveling surface in an arbitrary direction by independently rotating and driving left and right driving wheels by a pair of drive motors. The pair of drive motors is characterized in that they are arranged so as not to overlap in plan view when viewed from the side.
[0008]
Preferably, the pair of drive motors, the left and right drive wheels, and the pair of wheel trains provided so that power can be transmitted from both drive motors to both drive wheels are all provided inside the left and right drive wheels. Install on both sides of one mounting plate.
[0009]
【Example】
An embodiment of the present invention will be described below with reference to the drawings.
1 and 2 show a main part of a running body 1 of a horse racing game. As shown in the figure, the traveling body 1 causes the traveling body 1 to follow the traveling body 1 by using the magnetic force of the permanent magnets 4, 4 imitating a plurality of racing horses each placed on the course plate 2. In this way, a competitive game is established.
[0010]
The traveling body 1 can travel in an arbitrary direction on the traveling surface S by individually rotating a pair of driving wheels (tires) 7L and 7R by a driving device 6 provided therein. Control of the driving device 6 is performed by a control circuit unit 8 provided in front thereof.
[0011]
A power feeding unit 10 is mounted on a support plate 9 provided above the cover 5. The power supply unit 10 is provided with a plurality of power supply pins 11 and a plurality of trace sensor pins 12. In addition to these, the aforementioned permanent magnets 4 and 4 are attached to the power supply unit 10.
[0012]
The support plate 9 that supports the power supply unit 10 is supported by the two columns 13 and 13 so as to be movable up and down, and receives an upward biasing force by the compression coil springs 13a and 13a. The feeding pin 11 and the trace sensor pin 12 are elastically in contact with the lower surface of the course plate 2 by the urging force. In addition, auxiliary wheels 14 and 14a are attached to the front and rear positions of the power supply unit 10, so that the posture of the power supply unit 10 with respect to the course plate 2 is maintained in parallel.
[0013]
The course plate 2 is composed of a laminate of three layers, a sheet plate 2a whose upper layer has a property that the surface is slippery, a reinforcing plate 2b whose middle layer is rigid, a power feeding plate 2c whose lower layer has a power feeding surface, and the like. The tip of the power feeding pin 11 described above is in elastic contact with the power feeding surface, and power can be supplied to the driving device 6 from here.
[0014]
A traveling table 15 that supports and moves the model body 3 is placed on the upper surface of the sheet plate 2a. The permanent magnets 4, 4 described above are embedded in the lower surface of the carriage 15, and are arranged so as to cause an attractive action by pairing with the polarities of the magnetic poles of the permanent magnets 4, 4 on the power supply unit 10. It is.
[0015]
The driving device 6 is mounted on both sides of a mounting plate 16 provided in the shape of a partition wall at the center in the lateral width direction of the traveling body 1 at a position near the rear portion of the cover 5 (see FIGS. 2 and 4). The left drive motor 17L that drives the drive wheel (tire) 7L on the left side in the traveling direction is mounted on the right side of the mounting plate 16 that is erected in a partition wall shape at the center of the cover 5. A drive gear 18L constituting the left train wheel G is fixed to a drive shaft that penetrates the mounting plate 16 and protrudes to the left. A first gear 19L meshes with the drive gear 18L, and a pinion of the first gear meshes with a second gear 20L, and a pinion of the second gear meshes with a gear 21L that rotates integrally with the left tire 7L.
[0016]
A slit disk 22L that rotates integrally with the drive gear 18L is coaxially attached to the drive gear 18L. Above the slit disk 22L, a sensor 23L that detects the number of slits of the slit disk 22L when the motor rotates is provided, and both of them constitute an encoder that detects the rotational speed of the drive motor 17L.
[0017]
On the other hand, the right drive motor 17R for driving the drive wheel (tire) 7R on the right side in the traveling direction is mounted on the left side of the mounting plate 16, and the train wheel G is mounted on the right side of the mounting plate 16. As shown in FIG. 3, the right drive motor 17R and the left drive motor 17L are arranged so as not to overlap when viewed from the side. The arrangement of the right wheel train G conforms to the left side. The left and right drive motors 17L and 17R and the power supply pin 11 are connected by a flexible printed cable (FPC) not shown.
[0018]
When the drive motors 17L and 17R are arranged in this way, the pair of motors 17L and 17R and the respective wheel trains G are overlapped when projected from the rear, and the lateral width of the traveling body 1 is reduced. As a result, as shown in FIG. 2, it is possible to produce a competition on the course surface when the adjacent traveling bodies 1 are close to each other, and it is possible to produce a more thrilling competitive game. . At the same time, since the motor has a margin with respect to the lateral width of the traveling body 1, it is not necessary to use a thin motor when reducing the lateral width of the traveling body 1, and the output is reduced. It is possible to adopt a motor that has been used conventionally.
[0019]
In the right wheel train G, a reverse gear 24 (see FIG. 1) for changing the rotation direction of the gear train is interposed between the first gear 19R and the second gear 20R. This is because when the left and right drive motors 17L and 17R are mounted in the opposite direction, when the drive wheels (tires) 7R and 7L are rotated in the same direction, one drive motor and the other drive motor are in opposite directions. This is employed as a means for correcting the inconvenience that the traveling body 1 has been moved forward by rotating. That is, when the traveling body 1 is driven, both the drive motors 17L and 17R may be rotated forward or backward by interposing the reverse gear 24 in the gear train G on one side. The inconvenience due to the difference in performance characteristics due to rotation is eliminated.
[0020]
As described above, the drive device 6 is configured to be attached to both side surfaces of the mounting plate 16 provided in the shape of a partition wall on the left and right sides in the center portion of the cover 5. Although there is a risk of rollover due to damage, the outer distance of the tires 7R and 7L can be expanded to an arbitrary position in the lateral width direction of the traveling body with respect to increasing the distance, so there is no risk of rollover. It should be set as follows.
[0021]
Furthermore, in the present invention, as shown in FIG. 4, motors and trains are mounted on both sides of the mounting plate 16 and inside the drive wheels 7L and 7R. Since there is only the cover 32 that needs to be provided on the surface, the replacement work of the tires 7R and 7L can be facilitated. That is, in the prior art, since the tire replacement had to be performed with the cover / motor / wheel train holding base plate removed, it was extremely troublesome, but in the present invention, the tires 7R and 7L were not even removed. Since it can be attached and detached as it is, there is an advantage that maintenance is simplified.
[0022]
As shown in FIGS. 1 and 2, a sensor substrate 26 is attached to the lower surface side of the cover 5, and a sensor 27 that reads a barcode for detecting the position of the traveling method provided on the traveling surface is mounted. Auxiliary wheels 28 are provided before and after the sensor substrate 27 on the lower surface of the cover 5.
[0023]
A communication substrate 29 is attached to the upper surface side of the cover 5. A light emitting element (LED) 30 is mounted on the upper surface side of the communication substrate 29, and a photosensor 31 is mounted on the lower surface side. The light emitting element 30 and the photosensor 31 enable bidirectional communication with a communication unit (not shown) of the controller. The start / stop of the traveling body and the direction and speed of traveling can be controlled by the scenario transmitted from the controller.
[0024]
In this embodiment, the motor and a part of the train wheel are arranged so as to be shifted on the left and right projection planes, but only the motor may be shifted. Further, although there is one mounting plate, it is also possible to use two mounting plates and arrange them inside the drive wheels.
[0025]
【The invention's effect】
According to the present invention, it is possible to provide a competitive game machine that can enjoy a thrilling competitive game with the model body approaching due to the thinning of the traveling body, and it is not necessary to make the drive motor thin, which is expensive. Since it is possible to adopt a conventionally used motor without employing a motor, it contributes to a reduction in manufacturing cost of the traveling body.
[0026]
Furthermore, a pair of motors, left and right drive wheels, and a pair of wheel trains that transmit power from both drive motors to both drive wheels are mounted on both sides of a single mounting plate provided inside the left and right drive wheels. Therefore, there is an effect that it becomes easy to carry out regularly required maintenance such as tire replacement.
