Movable carrier and folding method therefor

A folding method for a movable carrier, wherein the movable carrier comprises a bottom frame assembly, a first support member, a link assembly, a position mechanism, a first unlock member, a second support member, and two carry members, the first support member has a first end portion pivotally connected to the bottom frame assembly, the link assembly comprises a link member and a first connect member, the link member is disposed at a second end portion of the first support member, the first connect member is pivotally connected to the link member and connected to the second end portion of the first support member through the link member, the position mechanism is disposed on the link assembly and corresponding to the first connect member, the first unlock member is disposed on the link assembly and connected to the position mechanism, the second support member and the first support member are crossingly connected, one end of the second support member is pivotally connected to the bottom frame assembly, and the two carry members are correspondingly disposed at two ends of the link assembly, the folding method comprising:

• separating the two carry members from the link assembly;
• folding a part of the second support member about a folding pivot portion of the second support member toward the bottom frame assembly, thereby carrying the first support member and the link assembly to move toward the bottom frame assembly;
• continuously pushing the folded second support member toward the bottom frame assembly to make the first unlock member contact the bottom frame assembly so as to carry the position mechanism to move, thereby changing the position of the first connect member relative to the link member;
• and
• continuously pushing the folded second support member toward the bottom frame assembly until the second support member is parallel to the bottom frame assembly.
