Extending and retracting device and vehicle step apparatus having the same |
摘要 |
An extending and retracting device for a vehicle-step apparatus includes a mounting bracket and step bracket. A first arm defines a first end pivotally connected to the mounting bracket and a second end pivotally connected to the step bracket. A second arm defines a first end pivotally connected to the mounting bracket and a second end. A third arm defines a first end pivotally connected to the second end of the second arm and a second end pivotally connected to the step bracket. A trajectory-control assembly is configured to connect the first arm to the second arm and/or third arm to control a "motion" trajectory of the step bracket. A vehicle-step apparatus includes a step member, the extending and retracting device, and a driving device driving the first arm and/or second arm to move the extending and retracting device between an extended position and a retracted position.
