CONSTITUTION:The guided golf cart detects a magnetic field from a guided line 11 by a pair of magnetic sensors 10, runs along the guided line 11, while controlling the direction of steering wheels 3, and can run on plural pieces of running paths by these magnetic sensors 10. Also, running loca of the steering wheels 3 and driving wheels 2 generated by runs are placed so as not to intersect with each other. Moreover, this guidance type golf cart is placed so as not to step on the guided line 11 by the steering wheels 3 and the driving wheels 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide type golf cart which detects a magnetic field generated from a guide wire embedded in a golf course and runs along the guide wire.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Laid-Open No. 58-183514 (G05D 1/03), this type of inductive golf cart has a mounting bracket having two magnetic sensors attached to its body. There has been a technique in which a golf cart can run on a plurality of running paths by horizontally shifting the mounting position.

However, with the above-mentioned structure, since there is only one steered wheel, the steered wheel may travel on the guide wire among a plurality of traveling paths, which causes the guide wire to be buried. There was a possibility of being dug up from the ground or cutting the guide wire.

[0004]

SUMMARY OF THE INVENTION According to the present invention, when a vehicle is moved by moving left and right stepwise with respect to one guide wire,
It is an object of the present invention to provide a guide type golf cart which has a simple structure, does not overlap the traveling loci of all wheels, and does not step on a guide line, that is, which is excellent in maintainability.

[0005]

SUMMARY OF THE INVENTION The present invention includes a main body on which a golf bag or the like can be placed, drive wheels driven by a motor, and a plurality of steered wheels that determine a traveling direction.
A magnetic sensor for detecting the magnetic field from the guide wire and controlling the direction of the steered wheels is provided, and it is possible to move to the left and right stepwise by the magnetic sensor, and the guide wire in any selection,
The driving wheels and the steered wheels have a positional relationship in which the running loci do not overlap.

[0006]

[Operation] When the traveling path of the main body is moved stepwise to the left and right by the magnetic coil that detects the magnetic field from the guide wire, the guide wire and the traveling loci of the drive wheels and the steered wheels overlap in any movement state. Run the main body without doing.

[0007]

An embodiment of the present invention will be described with reference to the drawings.

1 is a golf cart body according to the present invention,
The golf cart body 1 includes a pair of chassis (not shown) extending in the front-rear direction of the vehicle body, and a pair of drive wheels 2 rotationally driven by a motor (not shown) provided behind the chassis.
Steering wheels 3 are provided in front of the chassis, and the traveling direction is determined by the direction of the steering wheels 3. Further, 4 is a mounting table for mounting the golf bag 5 provided in front of the main body 1. Further, 6 is an operation panel for switching the main body 1 to an automatic mode in which the main body 1 travels along a guide line described later, or a manual mode in which the main body 1 travels manually. The operation panel 6 sets the travel speed to a desired speed. You can also change or operate the steering wheel to the left or right in manual mode. The manual mode at this time is to drive the main body 1 by the operation panel 6 regardless of the guide wire, and the automatic mode is to automatically drive the main body 1 according to the guide wire.

Reference numeral 7 denotes the chassis, the driving wheel 2 and the steering wheel 3.
The reference numeral 8 denotes a vehicle body cover which covers the upper part of the battery cover, and 8 denotes a battery cover which can be opened and closed at the time of replacement of a battery (not shown) or maintenance.

Reference numeral 9 denotes a control box housed in the vehicle body cover 7, and the control box 9 houses a control board and the like for controlling traveling of the main body 1.

Reference numeral 10 denotes a magnetic sensor for detecting the magnetic field generated by passing a current through the guide wire 11 buried in the ground in the automatic mode and steering the steered wheels 3 along the guide wire 11. Four magnetic sensors 10 are attached by a T-shaped support plate 12 so as to intersect in a direction perpendicular to the traveling direction of the main body 1. And the magnetic sensor 10 is a set of two,
The respective detection intensities are measured so that they pass exactly through the two centers, and the deviation of the detection intensities results in the guide line.
The steered wheels 3 are controlled so that the main body 1 travels on the vehicle. Further, the four magnetic sensors 10 are switched by a switch 13 provided in the control box 9 in the vehicle body cover 7, and can be switched in three ways depending on their combinations.

Reference numeral 14 denotes a first pulley for controlling an angle control motor (not shown) according to the deviation detected by the magnetic sensor 10.
Reference numeral 15 is a second pulley rotated from the first pulley 14 by a timing belt 16. Then, the steering wheel 3 is directionally controlled by the rotation of the second pulley 15, and the traveling direction of the main body 1 is determined.

Next, the operation will be described.

When the main body 1 travels on the guide wire 11, that is, during automatic traveling, the pair of magnetic sensors 10 detect the magnetic field from the guide wire 11, and the deviation causes the guide wire 11 to be located at the center of the magnetic sensor 10. It is designed to run in position. When it is about to deviate from the guide wire 11 or when the guide wire 11 is bent, the deviation of the magnetic sensor 10 is calculated to calculate the steering wheel 3
Is rotated so that the main body 1 runs along the guide wire 11.

In the above running method, the combination of the magnetic coils 10 for detecting the guide wire 11 is changed by switching with the switch 13, and as shown in FIG. 1, the pair of magnetic sensors 10 shown in FIG. Since the vehicle travels along the guide wire 11 by detecting the magnetic field of A, B, C, C, three different laterally-shifted traveling paths are formed.

At this time, as shown in FIG. 1, it can be seen from the running loci of the golf carts above that the running paths A, B, and C do not overlap. In detail,
Even if the travel locus of A is moved to the right, that is, to B, or the travel locus of A is moved to the left, that is, to C, the travel loci of the steered wheels 3 do not intersect across the guide wire 11 and two The steering wheels 3 are also arranged such that their traveling loci do not intersect with each other.

Further, the drive wheels 2 are also arranged so that the traveling loci of the steered wheels 3 and the drive wheels 2 do not intersect with each other when the main body 1 moves in three steps for three travel paths.

With the above-mentioned structure, the driving roads 2 and the steering wheels 3 do not overlap each other, and different driving roads can be run every day. This makes it difficult for the golf cart body 1 to make a rut, and does not impair the aesthetic appearance of the golf course. Further, since the guide wire 11 is not stepped on by the steered wheels 3 and the drive wheels 2, the maintainability is excellent. Further, since the traveling path can be changed by switching the switch 13, it can be performed by a simple operation.

As another embodiment, in this embodiment, 4
By switching the magnetic sensor 11 of each piece
Although switching to the stage, a plurality of running paths can be created by making the sensitivities of the two magnetic sensors 11 different from each other. At this time, a plurality of sensitivities are set so that the traveling paths of the steered wheels 3 and the driving wheels 2 do not overlap with each other, and by switching between them, the traveling path of the main body 1 can be made in three stages or more.

[0020]

According to the present invention, since the driving roads and the steered wheels do not overlap with each other, and different driving paths can be run every day, rut is less likely to occur and the appearance of the golf course course is impaired. There is no. Further, since the guide wire is not stepped on by the steered wheels and the drive wheels, it is possible to obtain an effect such as excellent maintainability.
