Referring to FIGS. 1 and 2, an embodiment 100 of the present invention includes a loading unit 120 and a driving unit 110. In particular, the loading unit 120 includes a follower 300 Load your baggage (LD). The follower 300 includes a seat 320 and idle rollers 310 on both sides of the shaft. In this state, the driving unit 110 drives the loading unit 120 to transfer the baggage (LD) to a predetermined place.

1 to 4, the driving unit 110 includes a housing 111, a motor 112, a speed reducer 113, a driving wheel 114, a battery pack 115, a wireless communication unit 116).

The motor 112 is provided at both sides of the housing 111 and is a known means for generating power for driving the driving wheel 114. The speed reducer 113 is connected to the motor 112, It is a means to transmit high torque by increasing or decreasing the speed during power transmission. The speed reducer 113 is also provided with a pair of the motor 112.

The driving wheel 114 is provided under the housing 111 and is driven by the power transmitted through the motor 112 and the speed reducer 113.

The motor 112, the speed reducer 113, and the driving wheel 114 are each a pair. Accordingly, the pair of driving wheels 114 can be rotated at different speeds by the motors 112 connected to the pair of driving wheels 114, thereby being steered to either side.

The battery pack 115 is a component for supplying power to the motor 112 and is detachably attached to the battery mounting portion 115a. A lever 115b for detachably attaching the battery pack 115 is provided at one side of the battery mounting portion 115a. The battery pack 115 is a rechargeable secondary battery that can be connected to the power cradle in a state of being mounted on the battery mounting portion 115a and can be charged. It is possible. Therefore, when an extra battery pack is provided and another battery pack is charged during operation, when the battery is completely consumed, the battery pack can be replaced with an extra battery pack and used immediately.

A wireless communication unit 116 is provided on the upper surface of the battery mounting part 115a and wirelessly communicates with a remote controller (see 200 in FIG. 6) to be described later.

A control panel 117 is provided at one side of the battery mounting portion 115a. The control panel 117 is provided with a power ON / OFF button 117a and an emergency stop button 117b.

The loading unit 120 is provided with a turntable 121 on its upper surface and a driven wheel 122 on its lower surface. The turntable 121 is configured so that the loading unit 120 can rotate freely only 360 degrees apart from the baggage when the baggage LD is loaded. Therefore, the turntable 121 is configured closer to the driving unit 110 side than the driven wheel 122.

The mounting part 120 is relatively thinner than the driving part 110 (d1 <d2 <d3). That is, according to the present invention, the driving unit 110 and the loading unit 120 are separately constructed, so that the thickness of the loading unit 120 can be reduced. As described above, if the thickness of the stacking unit 120 is reduced, it is very easy to load the baggage LD. That is, even if the baggage having a predetermined space from the bottom surface is not lifted, the loading unit 120 can be pushed through the space and loaded, and even if there is no space, the load can be raised by a forklift or hoist to be.

Although the driving part 110 and the mounting part 120 are separately formed, the mounting part 120 can be formed to have a small thickness, which is advantageous in that the mounting part can be easily mounted. However, since the turning radius is relatively large, . This affects workability within a limited space.

In this embodiment, the mounting portion 120 and the driving portion 110 are rotatably connected by the hinge shaft 130 in order to solve this problem. It is also understood that a step 140 is formed on one side of the mounting part 120 in order to make the mounting part 120 as thin as possible and to connect the mounting part 120 to the driving part with the hinge shaft 130. [

With this configuration, the present embodiment 100 is configured such that the turning radius is small while the stacking unit 120 is configured thin. 5, the turning radius is important when the baggage LD is transported in a narrow space. In this embodiment, the connecting structure of the turntable 121 and the hinge shaft 130 is used, Is small.

That is, the loading unit 120 may rotate separately from the baggage LD by the turntable 121. In this embodiment 100, the first steering angle? Is about 4.5 degrees.

The driving unit 110 and the loading unit 120 are connected to each other by the hinge shaft 130 so that the secondary steering can be performed. The hinge shaft 130 and the turn table 121 allow the maximum allowable steering angle? ) Is 37 degrees. Of course, the primary steering angle? And the maximum allowable steering angle?
