The present invention relates to an electric cart that is used to transport multiple carts at once to relocate and collect carts that are directly dragged and transported by a user at a large mart or department store or airport, and more particularly, to the electric power of a motor. It is easy to transport several carts by itself, and the charger is built-in so that it can be charged by itself, and it is easy to use by using both hand operation and remote control operation, and the user sits on the chair by a separate chair. The present invention relates to an electric cart for transporting a cart that can be simultaneously transported by an auxiliary cart that can be manipulated and mounted separately.

In general, a large discount mart or an airport, such as a cart is placed so that the user can directly carry a large amount of goods.

Such a cart is composed of a carrier, a handle, and a wheel for easy transportation.The user places an object on the carrier and then uses the handle to carry the shopping cart or carry a large amount of goods easily. Doing.

These carts are temporarily stored in the cart storage provided separately by the user after use, and the temporarily stored carts are transferred back to a single storage by the cart transport worker.

At this time, since a large number of carts stored in the temporary storage area are transported by a worker directly to a single storage area, the transport work is very difficult and difficult, and the work of bending a large number of carts during rotation is difficult. There is a difficult problem.

Therefore, there is a problem that the work efficiency of transporting and storing the trolleys stored in a plurality of temporary storage spaces in a single storage is significantly reduced, and inefficient work is performed.

Of course, a method of transporting using a forklift has been proposed, but it is a cause of polluting the indoor air of a large discount mart or an airport by the smoke from the forklift, and the operation of the forklift is difficult. have.

In addition, the transfer means using the electric power has been devised, but in this case, there is a problem that the production cost increases due to the complicated structure, and also the convenience of work is deteriorated by the worker having to walk in a state that is always walking. There is a problem.

In addition, there is no special function other than transporting a large number of carts, so from the practical point of view, the efficiency is greatly reduced and the operation is only possible by a switch provided in the handle, so that the effect is greatly reduced. There is this.

The present invention has been made to solve the problems caused by transporting a cart used in a large discount mart or airport, etc. to store in a single place, by using a combination of a manual method and a remote control method to operate the situation in the situation Not only can it be set and used, but also it can be transported by electric power to prevent air pollution or noise in the room, and it is equipped with a separate chair and an auxiliary cart to operate the operator while sitting on a chair. The purpose is to provide an electric cart for transporting carts that can be used as a means of transporting a separate load using the auxiliary cart.

As a means for achieving the above object, the present invention provides a cart for transporting a cart, comprising: a housing in which a plurality of frames are bent, welded to each other, and a battery inserted therein; A lower support frame having one side welded to the bottom of the housing and a connecting body welded to the end side; A side support frame in which one side is welded to both side outer surfaces of the lower support frame, and the front end side is bent upward from the front side of the housing; A bracket on which one side is welded to the lower end of the side support frame and two small wheels are rotatably mounted on the lower side; A drive unit having a wheel shaft rolled inwardly of the lower support frame, two drive wheels fastened to both sides of the wheel shaft, and a drive motor allowing rotation of the wheel; A cart connection part having one side fastened to the front end side of the bracket and an auxiliary wheel mounted at the bottom thereof; The bracket is characterized in that the lower end is welded to the front end side and the upper end side includes an operation unit having a forward / reverse switch electrically connected to the drive motor of the drive unit.

The cart fastening portion fastened to the front end side of the bracket may be hinged by the bracket and the hinge pin to be folded up and down.

A control unit is further interpolated inside the housing, and an upper end of the housing may further include a conversion switch electrically connected to the control unit to convert a manual operation and a remote control operation.

A safety device for stopping driving of the driving motor may be further provided at one end of the operation unit by cutting off the electricity of the driving motor which is electrically connected to the driving motor or the control unit.

A charger for charging the battery itself may be further inserted into a lower end side of the battery inserted into the housing.

A chair may be further mounted on the upper end of the lower support frame.

The connection body welded to the end side of the lower support frame may be further equipped with an auxiliary cart that can carry and carry a separate load.

Electric cart for transporting the cart according to the present invention made of the above characteristics, by fastening the lower side of the cart to the cart fastening portion by using the driving force of the drive motor to easily transport the cart to be stored in one place, conversion switch It can be used in combination with manual operation and remote control to improve the work efficiency and easy charging operation because the battery does not need to be removed / detached from the housing in order to charge the battery by the charger embedded in the housing. Do.

In addition, the operator can sit on a separate chair to carry the cart, which improves the convenience of the transfer and can be used as a means of moving a separate object using an auxiliary cart mounted on the connecting body. .

Hereinafter, the structure and operation of the present invention cart transfer electric cart will be described in more detail based on the accompanying drawings.
