The present invention relates to a folding and positioning structure for an electric walk-substituting vehicle, which essential ly consists of a main body, a pivotal rod, a chair and a positioning device. The pivotal rod is pivoted on the main body, and then a chair is pivoted on the pivotal rod. The positioning device is assembled on the proper location of the chair and provided with a handle and a pulling rope connected to the handle. The terminal of the pulling rope can be linked to a positioning block, which can inserted correspondingly to the folded positioning hole and an unfolded positioning hole all being formed on the bottom of the pivotal rod. Accordingly, it is convenient to spread out the chair to seat and fold the same inside the main body to achieve the best effect for reducing square measure thereof and warehousing, delivering…etc.本發明係有關於一種電動代步車收合定位結構,係於載具主體樞接有樞桿,再於樞桿上樞接椅具,並於椅具處組設有定位裝置,而該定位裝置係設有手把及相接之拉繩,並使拉繩末端與定位塊相連接,再使定位塊與樞桿底側設有之收合定位孔及展開定位孔對應插掣;藉此設計,即可便利將椅具展開乘坐,及收合折疊於載具主體內,而達到有效縮減材積,利於倉儲與運送等實施。(1)‧‧‧載具主體(12)‧‧‧支架(2)‧‧‧樞桿(3)‧‧‧椅具(4)‧‧‧定位裝置(41)‧‧‧槽道(411)‧‧‧止擋部(42)‧‧‧手把(43)‧‧‧拉繩(44)‧‧‧省力滑輪組(46)‧‧‧套筒
