The invention belongs to the technical field of vehicle-mounted bicycle brackets, and discloses a foldable rear dragging type bicycle frame which comprises a fixed frame assembly and a movable frame assembly, and the movable frame assembly is located at the rear end of the fixed frame assembly. The two turnover brackets are folded to the maximum extent in a translation dislocation folding mode, the two turnover brackets do not interfere with each other after being folded, it is guaranteed that the size is reduced after the turnover brackets are folded, meanwhile, after the turnover brackets are unfolded, the top end of the whole device can be kept in a flush state, and the turnover brackets can be folded to the maximum extent. Meanwhile, the front wheel and the rear wheel of the bicycle are located on the same straight line, the bicycle can be conveniently placed, the longest side size of the whole device after being folded is smaller than half of the longest side size when the device is unfolded, the bicycle frame is folded to the maximum degree, the limiting mode of the device after being unfolded can complete locking without special operation, and the packaging size is effectively reduced; the logistics cost is reduced, and the convenience degree after folding is improved.
本发明属于车载自行车托架技术领域,且公开了一种可折叠后拖式自行车架,包括固定架组件和活动架组件,所述活动架组件位于固定架组件的后端。本发明通过利用了平移错位折叠方式,将两个可翻转托架最大化折叠,不仅使得折叠后两个可翻转托架不会相互干扰,以及保证了折叠后体积的减小,同时在展开后,可保持整个装置的顶端处于平齐状态,同时自行车的前后轮处于同一条直线上,方便了自行车的放置,整个装置折叠后最长边尺寸不到展开时最长边尺寸的一半,对自行车架进行了最大程度折叠,且这个装置展开后的限位方式无需特别操作即可完成锁定,有效减小了包装体积,降低了物流成本,提高了折叠后的便捷度。
