The invention provides a folding type folding bicycle which comprises a bottom frame (6), a front frame (2), a rear frame (3), a left side frame (4) and a right side frame (5), when the folding bicycle is folded, the middle of the bottom frame (6) is pulled upwards to enable a front frame part (11) and a rear frame part (12) to be folded oppositely, a left matching structure (21) moves upwards from the lower end along a left guide structure (20), and a right matching structure (24) moves upwards from the lower end along a right guide structure (23); the front frame (2) and the rear frame (3) draw close to each other to link the parallelograms of the left side frame (4) and the right side frame (5) to draw close synchronously so as to lift the middle support, so that the front frame (2), the rear frame (3), the left side frame (4), the right side frame (5), the front frame part (11) and the rear frame part (12) draw close to each other and finally form a folded state, and the front frame part (11), the rear frame part (12) and the connecting seats can form a U-shaped storage space (16) with a downward opening; the volume can be reduced, and the capacity can be as large as possible.

    本公开提出一种对折型折叠车,包括底架(6)、前架(2)、后架(3)以及左侧架(4)、右侧架(5),当折叠时,向上拉动底架(6)中部使前框部(11)、后框部(12)相对折叠,而左配合结构(21)自下端沿左导向结构(20)向上运动,右配合结构(24)自下端沿右导向结构(23)向上运动,前架(2)和后架(3)相互靠拢连动左侧架(4)、右侧架(5)的平行四边形同步靠拢以抬升中支座,从而使得前架(2)、后架(3)、左侧架(4)、右侧架(5)、前框部(11)、后框部(12)相互靠拢并最终形成折叠状态,前框部(11)、后框部(12)与各连接座能构成开口朝下的U形收纳空间(16);本公开有利于体积做小,同时容量尽可能大。
