折叠自行车的车梁中部装有折叠接头， 车梁可在折叠接头处对折 180°。 折叠自 行车有单梁车和双梁车之分， 双梁车的两个梁上均有折叠接头， 自行车处于展开状 态时， 整车的强度、 刚性均可保证， 但两个梁的折叠接头的转动轴必须完全重合， 对制造精度要求高。 另外， 用户在折叠或展开自行车时要操作两个接头， 使用麻烦。 单梁折叠车结构简单， 使用方便， 但在自行车骑行进， 折叠接头承受了较大应力， 即使采用较粗、 管壁较厚的管材作车梁， 仍给人一种刚性欠佳的感觉。 实用新型内容  Folding bicycles are equipped with a folding joint in the middle of the beam, and the beam can be folded by 180 ° in half at the folding joint. Folding bicycles are divided into single-beam vehicles and double-beam vehicles. Double-beam vehicles have folding joints on both beams. When the bicycle is in the unfolded state, the strength and rigidity of the entire vehicle can be guaranteed, but the rotation axis of the folding joints of the two beams They must be completely coincident and require high manufacturing accuracy. In addition, the user has to operate two joints when folding or unfolding the bicycle, which is troublesome to use. The single-beam folding bike has a simple structure and is easy to use. However, when riding a bicycle, the folding joints bear greater stress. Even if a thicker pipe with a thicker wall is used as the beam, it still gives a feeling of poor rigidity.
