Abstract

A wheel driving apparatus for a moving apparatus is provided. The wheel driving apparatus includes a wheel, a driving motor to generate a driving power to rotate the wheel, a gear box to transmit the rotational force of the driving motor to the wheel, and a guide shaft movable vertically with respect to the base member, wherein the wheel, the driving motor, the gear box, and the guide shaft are connected integrally with each other to move vertically with respect to the base member in unison.

Claims

1. A wheel driving apparatus of a moving apparatus, comprising:

a wheel;

a driving motor to generate a driving power to rotate the wheel;

a gear box to transmit the driving power of the driving motor to the wheel; and

a guide shaft movable vertically with respect to a base member,

wherein the wheel, the driving motor, the gear box, and the guide shaft are connected integrally with each other to move vertically with respect to the base member in unison, and

wherein the guide shaft has a first end that is supported by the base member and a second end of the guide shaft that is supported on a wheel cover connected to the base member.

2. The wheel driving apparatus of claim 1, further comprising a spring member to elastically support the wheel, the driving motor, the gear box, and the guide shaft when moved in unison.

3. The wheel driving apparatus of claim 1, wherein the base member, the guide shaft, and the gear box form a module that is vertically movable.

4. The wheel driving apparatus of claim 2, further comprising a sliding protrusion that protrudes from a side of the gear box, and a guide slot to guide the movement of the sliding protrusion, wherein the sliding protrusion is vertically movable.

5. The wheel driving apparatus of claim 1, wherein the wheel cover is removably mounted on an upper portion of the base member.

6. The wheel driving apparatus of claim 5, wherein the gear box comprises a support member extending from a portion thereof to move along the guide shaft, and the spring member is disposed between the support member and the wheel cover.

7. The wheel driving apparatus of claim 6, further comprising a touch member extending from one side of the gear box to change a position according to ascending and descending movement of the gear box, and a switch disposed on the base member to correspond to the touch member, so that the driving motor stops operating when the touch member is brought into contact with the switch.
