Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric hand-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric hand cart, and more particularly, to a hand-operated electric hand cart which can be easily and safely moved without being subjected to a large force by being driven by an electric force when carrying and loading many loads.

A hand cart is a conveying device that allows an article to be loaded and easily moved through a wheel. The general structure of the hand cart includes a main frame having a longitudinal direction and a handle at an upper end, a loading section protruding from a lower portion of the main frame in a direction perpendicular to the rear side to load the articles, And a main wheel (wheel), respectively.

When the article is moved using the hand cart, the main wheel can be smoothly rotated on the flat surface so that the article can be easily moved. However, when a large number of articles are loaded, the movement or rotation is not easy. Therefore, there is a problem that it takes a lot of time and power to move, and there is a fear that the goods may be damaged during the transportation. For this purpose, a hand-operated cart driven by electricity has been filed, but it is difficult to control or control the speed by using a motor.

To this end, a power switch is installed on the handle and the power supply is shut off when the handle is released. When the power supply to the motor is interrupted, a motor brake is mounted to mount the brake, and a chain is formed between the wheel and the wheel So that the flow of electricity is smooth, and a power transmitting portion serving as a gear and a brake is formed.

According to the hand-operated electric hand cart as described above, it is advantageous in that a lot of loads can be easily moved without being easily subjected to large force by being rotated by the power of the motor.

In addition, since a part that functions as a power switch is formed on the handle, it is easy to drive electricity by holding the handle, and driving is stopped immediately when the handle is released due to the brake motor.

Hereinafter, features and configurations according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a front view of the pull-driven electric hand cart 10 of the present invention, Fig. 2 is a side view of the pull-driven electric hand cart 10 of the present invention, 4 is an enlarged view of the power transmitting portion 40 of the handle-driven electric hand cart 10 of the present invention.

The handle-driven electric hand cart 10 of the present invention is characterized in that the handle 11 and the body frame 12 connect the loading part 13 and the power supply part 14, the power connecting rod 15 and the wheels 16, And includes a driving switch line 17, a driving unit 20, and a power transmission unit 40.

1, a handle-driven electric hand cart 10 according to a front view of the present invention includes a loading unit 13 protruding rearward from a lower end and capable of transporting objects, and a handle 11 bent obliquely forward A power source connecting rod 15, a power supply unit 14, a driving unit 20 and a wheel 17 are mounted on the front side of the main body frame 12.

The driving switch line 17 of the hand-operated electric hand cart 10 of FIG. 2 connects the driving unit 20 and the power transmission unit 40 and is formed like a hot line inside the handle 11, The power supply unit 14 is driven to supply power to the driving unit 20.

The power supply unit 14 is a means for supplying power to the driving unit 20. It is preferable to use a rechargeable battery so as to reduce weight and minimize volume. The power supply connecting rod 15 provided below the power supply unit 14 connects the power supply unit 14 and the driving unit 20. The driving unit 20 is driven by a power source applied from the power supply unit 14, Thereby providing a rotational force to the transmitting portion 40.

An enlarged view of the driving unit 20 of Fig. 3 is an enlarged view of the brake motor.

When power is supplied to the brake motor, the current rectified in the power supply device flows to the brake coil, so that a strong magnetic force is generated in the brake stator 24 so that the armature 26 is instantaneously sucked, The motor rotates. Next, when the power is turned off, the attracting force of the magnet coil is extinguished, and the armature 26 is urged to the pacing by the pressure of the brake spring and rapidly brakes the load. The detailed description is the same as that of the brake motor, so it should be omitted.

The power transmitting portion 40 is provided to transmit the rotational force of the driving portion to the front wheel. The power transmitting portion 40 is provided with a function of switching the rotational direction of the driving portion 20 by the combination of the gear portion 45 and decelerating and stopping the rotational speed .

As shown in FIG. 4, when power is supplied to the power transmission unit 40 due to the driving unit 20, the connecting chain 43 functions to provide the driving force to the front wheels by receiving the power while the hand cart is being driven. (41) and the second power transmitting portion (42).

Although the technical spirit of the present invention has been specifically described according to the above preferred embodiments, it is to be understood that the above-described embodiments are intended to be illustrative and not restrictive. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
