More particularly, the present invention relates to a golf cart having a golf bag and a device mounted thereon, and a remote controller control method of moving the golf cart together with a golfer through communication with the remote controller, The present invention relates to an electric golf cart.

Since the Korean golfers have played an active part in the international golf competition in recent years, golf has become popular due to income increase and development of various golf related industries, and the golf population is continuously increasing.

Conventionally, when golfers play a game on a golf course, a round was played with a caddy called a caddy. For convenience, a golf bag containing a variety of golf clubs for a proper tee shot in various situations was put on the spot by a game assistant, .

However, one of the cost factors that hinders popularization of golf has been pointed out as a service fee for caddies to be used for carrying golf equipment, and as a means of transporting golf equipment in accordance with the demand of golf environment to enjoy golf at low cost A golf cart was proposed.

The manual golf cart which is mainly used at the beginning and which is the most inexpensive in terms of cost has a disadvantage in that it is somewhat uncomfortable to handle and a large amount of physical power is consumed due to the movement. Especially, since most golf courses are located along the mountains, the physical power consumption due to the movement of the cart is considerable in the sloping places.

In order to solve such a problem, a golf cart having an electric system classified into a riding system and a non-riding system has appeared. The riding system is generally referred to as a golf car because the riding system is a vehicle system. .

First, in case of a golf car, transfer of golf equipment is convenient, but since the golfer is directly carried on the board, the amount of momentum is reduced and conversation between golfers is not smooth during the field movement.

In addition, the electric golf cart is complicated in structure, heavy in weight, and inconvenient in handling, and requires a control such that the golfer grips the handle and switches the direction to the left and right as in the case of the manual golf cart, there was.

In the meantime, a technique has been developed in which a golf course is easily transported while a golfer is walking and moving while a rail or induction loop line is buried in a golf course and the cart runs along the golf course. However, And a problem that the lawn of a specific part is damaged as the user moves along a predetermined course continuously.

The wireless communication and position tracking between the communication unit 140 and the remote control terminal 200 are well known in the art, and a detailed description thereof will be omitted.

In addition, since the present invention is basically driven by electricity, it is equipped with a battery of a proper capacity which is charged through a power source supplied from the outside and can be supplied with sufficient power during a time when it is not inconvenient for enjoying golf with one full charge A power supply unit 150 is provided. In this case, the position where the power source unit 150 is installed may be selected from the first body 110 or the second body 120. When a somewhat large capacity battery is required, the first body 110 and the second body 120 120 formed on the outer surface of the first body 110 or the second body 120. The first body 110 and the second body 120 are connected to each other through a connector 151 do.

The control unit 160 may be a MCU for receiving power from the power supply unit 150 and controlling the steering unit 112, the driving unit 122 and the angle control unit 130, 200, and controls the steering unit 112, the driving unit 122, and the angle adjusting unit 130 according to the programmed contents, thereby moving the electric golf cart according to the present invention.

The remote control terminal 200 includes an operation button for operating the steering unit 112, the driving unit 122, and the angle control unit 130, and a user (golfer) A manual mode in which a control command inputted through the communication unit 140 is received through the communication unit 140 and controls the steering unit 112, the driving unit 122 and the angle control unit 130, The steering unit 112 and the driving unit 122 are controlled by a program that calculates the direction and distance of the remote control terminal 200 through the communication unit 140 and periodically tracks the distance and maintains a certain range of distance, An automatic method for controlling the angle adjusting unit 130 can be selectively used.

At this time, when the golf club is not used without using the golf cart, the first body 110 and the second body 120 are as close to each other as possible and the storage space can be saved, It is preferable to maintain the angle between the first body 110 and the second body 120 at an appropriate angle to ensure stability while maintaining the angle at the most stable angle of about 45 degrees when stopping , It is possible to adjust the height of the golf club to be a height at which the golf club can be taken out according to the height of the user.

In addition, in the preferred embodiment of the present invention, the first body 110 generates a control signal according to a user inputting a basic operation command including on / off control of the power supply, and transmits the control signal to the controller 160, And an input / output unit 170 for outputting various operation states so that the user can confirm the operation of the light unit 180. The light unit 180 can be used as illumination in response to a shady or dark weather condition, And the interface unit 170 and the write unit 180 are also controlled through the control unit.

As described above, when using the automatic method of automatically moving the user's location by tracking the position of the user, it is possible to calculate the location of the remote terminal 200 by simply calculating the location of the remote terminal 200 when moving in a field having various terrain, It is necessary to grasp it in advance and move through a stable path.

Recently, there are many fields that make the best use of the natural environment, and there are various obstacles to the movement, and there are artificial obstacles such as water, bunker, and curved surface of the floor, It is necessary to prevent the inability to move. The first body 110 or the second body 120 may be provided with a storage unit 161 for storing the geographical information of the field and a storage unit 161 for storing the geographical information of the field in cooperation with the geographical information of the storage unit 161, A position calculation section 162 for generating position information is additionally provided.

The geographical information is information on various obstacles and structures including the terrain information on the field, i.e. field, to which the golf cart according to the present invention can be moved. The geographical information is created through drawings and maps according to the construction of a golf course and stored in the storage unit 161 do.

The position calculating unit 162 includes an electronic circuit to calculate a current position, and can be realized through a GPS module which is the simplest and most accurate. The position calculator 162 generates position information including the current golf cart position, moving direction, speed, and the like, and links the current position with the geographical information retrieved from the storage unit 161, It is possible to know which structure is present in which direction and at a certain distance, and a path that can be moved away from such a structure can be calculated.

Corresponding to this, the control unit 160 determines the traveling direction by reflecting the geographical information of the storage unit 161 and the position information of the position calculating unit 162, and controls the steering unit 112 And controls the driving unit 122 and the angle adjusting unit 130. It is preferable that the remote control terminal 200 is traced and moved to the shortest distance so that a predetermined structure to be avoided is avoided within the shortest distance The path is calculated.

In addition, according to the present invention, since the golf bag B having a relatively long and heavy weight is loaded and the first body 110 and the second body 120 are folded, Left and right balances are important. In other words, if the center of gravity of the gravity center does not match the direction of progression in a relatively large slope, there is a possibility of overturning to the left and right sides.

To this end, the first body 110 or the second body 120 is provided with a horizontal sensor unit 163 for measuring the horizontal and vertical directions of the front and rear and left and right directions, In response, the controller 160 calculates the left and right horizontal angles before and / or during the driving of the driving unit 122, stops the driving by controlling the driving unit 122 when the inclination exceeds a set level, The driving unit 122 and the angle adjusting unit 130 are controlled so as to turn the steering unit 112 in the direction in which the tilt of the slope relative to the right and left direction can be minimized.

As shown in the drawings of the preferred embodiment, the electric golf cart according to the present invention basically has a shape that is vulnerable to inclination in the lateral direction rather than inclination in the forward and backward directions. Of course, there is a method of increasing the lateral width of the first body 110 and the second body 120 in order to prevent this, but it has not only an unnecessarily large volume and weight but also a poor result in terms of steering performance.

Therefore, in order to compensate for the weakness of the inclination in the left and right direction, it is preferable to control the inclination direction at the time of stop in the inclined section to stop in the forward and backward directions of the body, The second body 120 can be placed in a downward sloping direction, and thus a more stable state can be obtained.

It is to be understood that the invention is not limited to the disclosed embodiment, but is capable of many modifications and variations within the scope of the appended claims. It is self-evident.
