Abstract

本发明公开了一种折叠自行车，其后叉与车架铰接，车梁上装有折叠接头，后叉上有顶杆，顶杆与车架相抵，其车梁略呈S型，后叉与车架的铰轴与车架的中轴呈一夹角。其水平铰轴与车架中轴呈一夹角，后叉向前卷折时，后轮偏向车梁的一侧，而不在车梁的下方，其折叠后高度可仅为轮高，因而较低。同时，其车梁呈s型，前、后轮分别折叠于S型车梁两侧的凹弧段内，折叠更加紧凑，折叠后的厚度更小。

Description

一种折叠自行车
技术领域
本发明涉及一种折叠自行车，特别涉及一种可多点折叠的折叠自行车。
技术背景
通常的折叠自行车，其车梁上有一个折叠接头，车架可在该处侧向折叠，使前、后轮基本并拢，其折叠后车架突出，如图1，体积较大，不便于包装、携带。英国专利有一种折叠自行车，如图2，其车梁上有一折叠接头，后叉与车架铰接，其车的前部可通过折叠接头侧向折叠，而车的后叉则可绕铰轴6a向前卷折，俗称卷型车，因该车两处折叠，其折后车架被夹在两车轮之间，不突出，体积较小，如图3。然其铰轴6a与中轴7a平行，卷折后，后轮8a位于车梁3a的下方，其折叠后车梁高度高于车轮，略嫌偏高。同时，为了下方能够放置后轮，车架车梁上拱，其既不够美观自然，又影响强度和刚度。此外，铰轴与中轴平行，影响折叠的角度，其折叠后厚度较大。
发明内容
本发明的目的在于提供一种折叠后体积更小的折叠自行车。
本发明所述的折叠自行车，车梁上装有折叠接头，后叉与车架铰接，后叉上有顶杆，顶杆与车架相抵，车梁略呈S型，后叉与车架的铰轴，与车架中轴呈一夹角。
本发明所述的折叠自行车，其水平铰轴与车架中轴呈一夹角，后叉向前卷折时，后轮偏向车梁的一侧，而不在车梁的下方，其折叠后高度可仅为轮径的高，因而较低。车梁呈s型，前、后轮折叠后分别处于S型车梁两侧的凹弧段内，其折叠更加紧凑，折叠后的厚度更小。综上，本发明的卷型车其折叠后的体积无论高度还是厚度都可更小。
附图说明
图1通常折叠自行车折叠后的立体图；
图2是现有的另一种折叠自行车的结构示意图；
图3是图2折叠后的示意图；
图4是本发明的卷型车的结构示意图；
图5是图4的俯视图；
图6是图5折叠后的示意图；
图7是图6的俯视图；
图8是顶杆与车架连接处的剖视图。
具体实施方式
如图4、图5，一种折叠自行车，其后叉2与车架1铰接，车梁3上装有折叠接头4，后叉2上有顶杆5，顶杆5与车架1相抵，其车梁3略呈S型，后叉2与车架的铰轴6与车架的中轴7呈一夹角θ。后叉2向前卷折时，后轮8偏向车梁3的一侧，而不在车梁3的下方，其折叠后高度可仅为车轮高，如图6，因而较低。车梁3呈s型，前轮9与后轮8分别折叠于S型车梁3两侧的凹弧段内，如图7，其折叠更加紧凑，折叠后的厚度更小。上述折叠自行车其折叠后的高度和厚度均可更小，因而折叠后体积可更小。
为了保证折叠后后轮8能够紧贴于车梁3的一侧而不致于偏差过大，铰轴6与中轴7的夹角θ应控制在1°到5°之间。
上述折叠自行车，骑行于高低不平的路面时，由于颠簸，顶杆5与车架1相抵处容易脱离并碰撞，其带来的较大振动和噪声，影响骑行的安全和舒适。为了避免上述情况，如图8，其顶杆5上端可制成或者安装呈球形凸头10，车架1与之相应位置有厚塑胶套管11，车展开时，凸头10插入塑胶套管11的孔12中。车辆颠簸时，厚塑胶套管11可通过适当的变形来适应道路的颠簸，同时，凸头10与套管11间的摩擦力较大，其不易脱开和碰撞，因而噪音和振动更小，骑行更舒适。
为了进一步提高卷型车的强度，可车架1上焊接一加强筋13，该加强筋13同时焊接于车梁3、座管14和用于铰接后叉2的铰接管15上，如图4。
