Abstract
Disclosed is a guide module and a driving device having the guide module. The driving device includes a moving unit mounted on a pinion interacting with a rack and moving with the pinion along a trajectory of the rack, and a guide module arranged at at least any one side of the rack, connected to the moving unit, and guiding a movement of the moving unit that moves with the pinion along the trajectory of the rack.
Claims20
A driving device comprising:
- a moving unit mounted on a pinion interacting with a rack and moving with the pinion along a trajectory of the rack;
- and
- a guide module arranged at at least any one side of the rack, connected to the moving unit, and guiding a movement of the moving unit that moves with the pinion along the trajectory of the rack, wherein the guide module comprises:
- a module rail forming the same trajectory as the rack at one side of the rack;
- and
- a running portion comprising a plurality of running wheels guided to run on a side wall of the module rail, and a running wheel connection block arranged across the module rail and connected to the plurality of running wheels,
- wherein the guide module further comprises a front steering portion connected to the running portion in front of the running portion, and
- the front steering portion comprises:
- a plurality of front steering wheels steered and guided to run on the side wall of the module rail when passing a curved section of the module rail;
- and
- a front steering wheel connection block arranged across the module rail and connected to the plurality of front steering wheels,
- wherein the guide module further comprises a rear steering portion symmetrically arranged to the front steering portion and connected to the running portion at the back of the running portion, and
- the rear steering portion comprises:
- a plurality of rear steering wheels steered and guided to run on the side wall of the module rail when passing the curved section of the module rail;
- and
- a rear steering wheel connection block arranged across the module rail and connected to the plurality of rear steering wheels.
A guide module which is arranged at at least any one side of a rack that interacts with a pinion, connected to a moving unit that moves with the pinion along a trajectory of the rack, and guides a movement of the moving unit, the guide module comprising:
- a module rail forming the same trajectory as the rack on one side of the rack;
- and
- a running portion comprising a plurality of running wheels guided to run on a side wall of the module rail, and a running wheel connection block arranged across the module rail and connected to the plurality of running wheels,
- further comprising a front steering portion connected to the running portion in front of the running portion,
- wherein the front steering portion comprises:
- a plurality of front steering wheels steered and guided to run on the side wall of the module rail when passing a curved section of the module rail;
- and
- a front steering wheel connection block arranged across the module rail and connected to the plurality of front steering wheels,
- further comprising a rear steering portion arranged symmetrically to the front steering portion and connected to the running portion at the back of the running portion,
- wherein the rear steering portion comprises:
- a plurality of rear steering wheels steered and guided to run on the side wall of the module rail when passing a curved section of the module rail;
- and
- a rear steering wheel connection block arranged across the module rail and connected to the plurality of rear steering wheels.
