WHEEL BASE FOR MOVING STRUCTURE

摘要

PURPOSE: A wheel base of the movement structure is provided to easily control the gap between the wheels which located in the front and the rear direction and steadily move the movement structure in the indoor and the outdoor. CONSTITUTION: The wheel base (100) which located between the front wheel and the rear wheel of the movement structure connects the front wheel and the rear wheel. The wheel base comprises the first frame unit (101) connected to one between the front wheel and the rear wheel; the second frame unit (102) that is connected to one of the front wheel and the rear wheel and connected to the top or bottom of the first frame to be coupled to the first frame unit; the slider unit (103) that is located within the accommodation space and coupled to one between the first frame unit and the second frame unit; an operation unit (105) that located the other cross section between the first frame unit and the second frame unit and generates the driving power; and a driving delivery unit (104) that connects the operation unit and the slider unit and delivers the driving power to the slider unit. The operation unit controls the gap between the front wheel and the rear wheel by moving the slider unit to a longitudinal direction of one between the first frame unit and the second frame unit.
