Walking pad

Abstract

A walking pad includes an alignment structure, a first walking pad and a second walking pad which is foldable onto the first walking pad, where the alignment structure includes a first matching element connected to the first walking pad and a second matching element connected to the second walking pad, the first matching element is configured to be able to abut against the second matching element, a first abutting surface of the first matching element is matched with a second abutting surface of the second matching element, and a top surface of the first walking pad and a top surface of the second walking pad are on a same plane when the first matching element abuts against the second matching element. The walking pad can eliminate the feeling of unevenness between the first walking pad and the second walking pad.
