具体实施方式
以下结合附图对本发明的原理和特征进行描述，所举实例只用于解释本发明，并非用于限定本发明的范围。
如图1所示，一种超级省力自行车，包括前轮总成1、后轮总成2、把手3、脚踏板4、车架5、连杆6、摆杆7、座椅8和用于将摆杆7的摆动力传递给后轮总成2的传动机构，连杆6和摆杆7均为伸缩杆。车架5为三脚架。前轮总成1和后轮总成2分别安装在车架5的前后两端，脚踏板4的可转动安装在车架5中部的下端，摆杆7和脚踏板4分别铰接在连杆6的两端，座椅8固定在连杆6和摆杆7的铰接端，摆杆7远离座椅8的一端铰接在车架5前端且通过传动机构与后轮总成2传动连接。
具体的，前轮总成1和后轮总成2为常规的自行车车轮结构，均包括轮轴、辐条、轮辋和轮胎，轮胎固定在轮辋上，轮辋通过辐条固定在轮轴上。连杆6和摆杆7均包括内杆和外筒，内杆的一端滑动连接在外筒内并通过螺钉锁紧，能够通过调节连杆6和摆杆7的长度来适应不同身高体型的人。
如图6所示，脚踏板4的一端与车架5铰接并在铰接端沿远离脚踏板4的方向延伸有摇杆11，摇杆11远离脚踏板4的一端与连杆6铰接，摇杆11与脚踏板4呈夹角α布置，其中180°≤α≤179°。
车架5下部设有用于限制摆杆7下行位移的高度可调的支座9，支座9同样包括内杆和外筒，内杆的一端滑动连接在外筒内并通过螺钉锁紧，支座9的底部固定在车架5下部，支座9的顶部安装有缓冲垫10，缓冲垫10位于摆杆7中部的正下方，缓冲垫10为U型结构，为海绵材质，摆杆7能够卡入缓冲垫10内，当骑行者身高体重不同时，能够调整支座9的高度来限制摆杆7上下摆动的幅度，避免摆杆7摆动过度而损坏；由于摆杆7远离座椅8的一端铰接在车架5前端上，因此摆杆7以车架5前端为转轴转动，从而能够上下摆动，通过支座9来限制摆杆7上下摆动位移的高度，当摆杆7向上摆动时，摆杆7远离缓冲垫10，当摆杆7向下摆动时，到达最底部位置后，摆杆7中部位置与缓冲垫10接触，摆杆7置于缓冲垫10内，使得缓冲垫10和支座9对摆杆7形成限制，防止摆杆7继续向下摆动。摆杆7上固定有扇形齿轮12，扇形齿轮12的弧形角度为90-120°，扇形齿轮12的侧边与摆杆7靠近车架5的一端的侧边固定连接，使得扇形齿轮12的虚拟圆心与摆杆7的端头重合，扇形齿轮12的外环壁上设有轮齿，随着摆杆7绕车架5前端转动，带动扇形齿轮12同时转动，车架5安装有与扇形齿轮12啮合的第一飞轮13，第一飞轮13通过传动机构与后轮总成2传动连接。
传动机构包括第二飞轮15、第一链条14和第三飞轮16，第二飞轮15的直径大于第三飞轮16的直径，第二飞轮15的直径大于第一飞轮13的直 径，第二飞轮15与第一飞轮13同轴固定连接，第三飞轮16通过第一链条14与第二飞轮15传动连接，第三飞轮16的中心轴与后轮总成2相连接。
本发明中的飞轮，为现有技术，具体结构不再详细描述，具体均可采用申请号为CN201620691351.6，名称为一种脚蹬正转反转均能前行的健身自行车中记载的第三飞轮。
实施例1
如图2所示，传动机构还包括中间飞轮17，脚踏板4在与车架5铰接的一端垂直延伸有转动轴，中间飞轮17固定套设在转动轴上，第二飞轮15、中间飞轮17和第三飞轮16通过第一链条14传动连接。
如图3和图4所示，骑行时，人臀部坐在座椅8上，脚放于脚踏板4上，座椅8通过臀部支撑整个人体的重量，座椅8受力后自然向下移动，同时带动摆杆7靠近座椅8的一端下摆，连杆6同样向下移动，使得脚踏板4发生转动，从而倾斜向上，摆杆7靠近前轮总成1的一端绕车架5前端为转轴顺时针转动，从而带动扇形齿轮12绕车架5前端为转轴顺时针转动，带动第一飞轮13逆时针转动，从而带动第二飞轮15逆时针转动，第一链条14转动，第三飞轮16带动后轮总成2逆时针转动，车辆向前行驶；与此同时，连接轴与中间飞轮17停止传动，中间飞轮17仅与第一链条14之间传动。再经由脚发力向下踩动脚踏板4，臀部向上，此时人体不坐在座椅8上，由人体自重给脚踏板4施加向下的力，带动连杆6向上移动，摆杆7靠近座椅一端向上摆动，摆杆7靠近前轮总成1的一端绕车架5前端为转轴逆时针转动，带动扇形齿轮12绕车架5前端为转轴逆时针转动，带动第一飞轮13顺时针转动，由于棘轮结构，第一飞轮13顺时针转动时，第二飞轮15不受力，第二飞轮15不会转动，而此时由于转动轴直接带动中间飞轮17逆时针转动，通过中间飞轮17带动第一链条14，从而带动第三飞轮16和后轮总成2逆时针转动，继续向前行驶，此过程与普通自行车上结构相同，不再重复描述具 体结构。重复上述过程，完成自行车的骑行。另外，由于脚踏板4、连杆6和座椅8之间的杠杆作用，向脚踏板4施加的向下的力能够在座椅8处变成数倍的力，带动摆杆7摆动的时候更省力。
实施例2
如图5所示，本实施例与实施例1的区别在于，传动机构包括第二链条18、第三链条19、第五飞轮23、第四飞轮22、过渡飞轮20和中间链盘21，脚踏板4与车架5转动连接处垂直延伸有转动轴，过渡飞轮20套设在转动轴上，中间链盘21与过渡飞轮20同轴布置且固定连接在过渡飞轮20的外盘体上，第五飞轮23与第一飞轮13同轴固定连接，第五飞轮23的直径大于第一飞轮13的直径，第五飞轮23与过渡飞轮20通过第二链条18传动连接，中间链盘21与第四飞轮22通过第三链条19传动连接，第四飞轮22与后轮总成2连接。第五飞轮23的直径大于中间链盘21的直径，中间链盘21的直径大于第四飞轮22的直径，第四飞轮22的直径大于过渡飞轮20的直径。
具体的，过渡飞轮20包括棘轮盘和连接有棘爪的外盘，外盘和棘轮盘通过棘爪完成传动或者停止传动，中间链盘21和过渡飞轮20同轴布置并且与过渡飞轮20的外盘相连接。保证当脚踏板4顺时针转动，第五飞轮23逆时针转动时，转动轴带动棘轮盘顺时针转动，棘轮盘和外盘之间无传动关系，同时外盘受第二链条18带动逆时针转动从而带动中间链盘21逆时针转动，保证后轮总成2能够向前行驶。
骑行时，人臀部坐在座椅8上，脚放于脚踏板4上，座椅8通过臀部支撑整个人体的重量，座椅8受力后自然向下移动，同时带动摆杆7靠近座椅8的一端下摆，脚踏板4倾斜向上，从而摆杆7靠近前轮总成1的一端绕车架5前端为转轴顺时针转动，带动扇形齿轮12绕车架5前端为转轴顺时针转动，带动第一飞轮13逆时针转动，带动第五飞轮23转动，第二链条18 转动，带动过渡飞轮20转动，过渡飞轮20带动中间链盘21转动，第三链条19转动，从而带动后轮总成2逆时针转动，车辆向前行驶；与此同时，连接轴与中间飞轮17停止传动，中间飞轮17仅与第二链条18之间传动。再经由脚发力向下踩动脚踏板4，臀部向上，由人体自重给脚踏板4施加向下的力，带动连杆6向上移动，同时摆杆7靠近座椅一端向上摆动，摆杆7靠近前轮总成1的一端绕车架5前端为转轴逆时针转动，带动扇形齿轮12绕车架5前端为转轴逆时针转动，从而带动第一飞轮13顺时针转动，此时第五飞轮23停止转动，同时由转动轴直接带动过渡逆时针转动，通过过渡飞轮20带动中间链盘21转动，从而经第三链条19带动第四飞轮22和后轮总成2逆时针转动，继续向前行驶。重复上述过程，完成自行车的骑行。另外，由于脚踏板4、连杆6和座椅8之间的杠杆作用，向脚踏板4施加的向下的力能够在座椅8处变成数倍的力，带动摆杆7摆动的时候更省力。
实施例3
如图7所示，本实施例与实施例1的区别在于，后轮总成2上设有第二座椅24，第二座椅24固定在车架5上，座椅8后端安装有扶手23。使用时，第二座椅24和座椅8均可载人。骑乘时，第二座椅24上的人手握住扶手23，上压或者下压扶手23，起到助力作用。
具体的，扶手23包括手握部和两个分别垂直连接在手握部两端的连接部，两个连接部分别固定在座椅8上。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
