According to the folding bicycle frame and the folding bicycle provided by the invention, on the premise of ensuring the portability of the folding bicycle, the folding bicycle frame realizes the maintenance of an unfolding posture through the matching of the plug pin and the positioning blind hole; a small-range relative movement space is reserved for the front frame and the rear frame through the size design of the positioning blind holes in the corresponding direction, and on the basis, the hidden damping mechanisms are arranged in the positioning blind holes, so that on one hand, the situation that the folding performance of the folding frame is affected by exposure of the damping mechanisms can be avoided, and on the other hand, the protection performance of the damping mechanisms can be improved; and the damping mechanism is more durable.
本发明提供一种折叠车架及折叠自行车,在保证折叠自行车的便携性能的前提条件下,该折叠车架通过插销与定位盲孔的配合实现展开姿态的保持,利用定位盲孔在对应方向上的尺寸设计为前车架和后车架预留了小范围的相对运动空间,在此基础上于定位盲孔内设置了隐藏式的减震机构,一方面可避免减震机构的外露影响折叠车架的折叠性能,另一方面可提高减震机构的防护性,使得减震机构更耐用。
