1. A stair lift, comprising:
a carrier portion;
a lift portion;
a driver mechanism, provided with a single driver source;
an up-down directional moving mechanism, configured for inducing a relative movement between the carrier portion and the lift portion in an up-down direction;
a front-rear directional moving mechanism, configured for inducing a relative movement between the carrier portion and the lift portion in a front-rear direction;
a first locking means, configured for locking the up-down directional moving mechanism; and
a second locking means, configured for locking the front-rear directional moving mechanism;, wherein
the up-down directional moving mechanism and the front-rear directional moving mechanism are respectively driven by different output forms of the driver mechanism;
the first locking means and the second locking means are alternately locked, and at the same time, the driver mechanism sequentially moves the carrier portion and the lift portion relative to each other in the front-rear direction or the up-down direction, such that the lift portion and the carrier portion perform translational movements relative to each other along a closed circulation motion track with constant postures, whereby going upstairs or downstairs.
