具体实施方式
如图 1所示， 多功能自行车， 包括头管 1、前叉 2、前轮 3、后轮 4、立管 5、 后货架 6和横梁 7， 后轮 4直径大于前轮 3的直径， 所述前轮的中轴 8位于头管 1的后方， 前轮 3的中轴 8通过导向杆 9与前叉 2连接， 减震弹簧 10—端固定 在下固定块 11上， 另一端固定在上固定块 12上； 下固定块 11上设置有调节通 孔 13， 下固定块 11通过调节通孔 13安装在前轮的中轴 8上； 上固定块 12固定 在前叉 2上。 导向杆 9一端固定在前轮的中轴 8上， 另一端铰接在前叉 2的端 部。
为了使本发明为折叠式自行车， 使横梁 7的后端部套装在立管 5上， 且横 梁 7与立管 5之间设置有锁紧螺杆 14。锁紧螺杆 14一端铰接在立管上， 另一端 通过螺母 15固定在横梁 7上。 由于自行车的前部和后部通过横梁连接在一起， 而横梁的后端套装在立管上， 当锁紧螺杆去掉时， 横梁可以绕着立管转动， 这 样就能够使自行车的前部与后部折叠在一起， 当使用时， 用螺母 15将锁紧螺杆 锁紧在横梁上， 这样自行车能够正常行驶。
为了使本发明的后货架具有多种功能， 后货架包括座体 61、杆体 62和弹簧 63， 座体 61固定安装在连接体 64上， 连接体 64铰接在杆体 62上； 杆体 62安 装在立管 5上； 弹簧 63的一端安装在连接体 64上， 另一端安装在杆体 62上。 如图 3所示， 当座体位于水平状态时， 杆体顶住座体的下表面， 安装在连接体 上的弹簧一端位于安装在杆体上的弹簧一端的下方， 此时， 后座可以放置货物、 承载人； 如图 4所示， 当座体位于竖直状态时， 杆体顶住座体的前端面， 此时 后座可以当做靠背。 上述弹簧两端位置的设置， 是为了固定座体水平和竖直状 态时的位置， 当座体处于水平状态时， 安装在连接体上的弹簧一端位于安装在 杆体上的弹簧一端的下方， 弹簧的拉力能够使座体固定， 当对座体施加向上的 推力时， 座体能够自动弹起， 呈竖直状态。
为了使本发明的横梁适用不同的人群， 可以把横梁做成多种形状， 如图 1 所示， 横梁为弯曲状横梁； 如图 2所示， 横梁为直线型横梁。
如图 5所示， 为了使本发明能够调节车把与人之间的距离， 根据不同人的 身高来调节车把， 头管通过把立安装车把， 把立包括用于安装车把的子管 18和 安装在头管的套管 19， 子管活动安装在套管内， 子管 18与套管 19之间通过定 位销 20定位。
如图 5所示， 为了使本发明能够更方便地避免雨水洒落身上， 在前轮和后 轮的上方均设置有可伸缩的泥瓦 16，泥瓦通过支撑筋 17安装在自行车前轮和后 轮的中轴上， 由于泥瓦为可伸缩的泥瓦， 在不使用时， 可以把泥瓦缩至一处， 方便放置， 在使用时， 可将缩在一起的泥瓦拉出， 通过支撑筋安装在前轮和后 轮的中轴上， 方便使用。
如图 6所示， 本实施例中:与前轮 3相连的前叉 2呈向后折弯状， 与前叉 2 相连的头管 1上设有挡杆 108， 前叉 2上设有与挡杆 108配合的挡板 103。 挡杆 108可以是固定在前叉 2上的螺栓或者其他物质，当车把受到外力作用突然拐弯 的时候， 挡杆 108碰到挡板 103不能继续转动， 防止因突然拐弯给骑车者带来 危害。
更优的， 支脚 106设置在脚蹬转轴和后轮轴中间， 这样设置支脚， 可以使 得停车更稳定。
更优的， 如图 7所示， 车座 105与立管 5相连， 所述车梁 7包括上横梁 7-2 和斜横梁 7-1， 立管 5上的凸起可沿斜横梁 7-1上的滑槽滑动， 立管 5下端设有 减震弹簧 11119。 这种结构可以在凸凹不平的路上， 减小车座上的震动。
另外， 所述前轮 3和后轮 4上连有风斗 220。在运行的时候， 风斗可以充分 利用自然风， 促进自行车前行， 顶风、 顺风风斗 20都能起到作用， 风斗也可以 安装在前后车轮轴两端。
