以下结合附图和具体实施例对本发明作详细描述。注意，以下结合附图和具体实施例描述的诸方面仅是示例性的，而不应被理解为对本发明的保护范围进行任何限制。
在本技术方案中，自行车本体包括自行车的车架1、轮胎、脚踏、刹车、链条等25个部件，其基本部件缺一不可。其中，车架1是自行车的骨架，它所承受的人和货物的重量最大。按照各部件的工作特点，大致可将其分为导向系统、驱动系统、制动系统：
1.导向系统：由车把53、前叉11、前轴、前轮61等部件组成。乘骑者可以通过操纵车把53来改变行驶方向并保持车身平衡。在本技术方案中因划桨动力系统4的加入，导向系统形成了新的结构，在后续记载中会详细描述。
2.驱动(传动或行走)系统：由脚蹬、中轴34、牙盘31、曲柄、链条、飞轮、后轴、后轮62等部件组成。人的脚的蹬力是靠脚蹬通过曲柄，链轮、链条、飞轮、后轴等部件传动的，从而使自行车不断前进。在本技术方案中划桨动力系统4需要与牙盘31进行联动，其结构上有改变，在后续记载中会详细描述。
3.制动系统：它由车闸部件组成、乘骑者可以随时操纵车闸，使行驶的自行车减速、停驶,确保行车安全。
以上自行车的基本部件为理解本技术方案的前提必要。
本发明的目的是对于现有技术缺点，提供一种双动力模式的自行车来实现不同部位的锻炼效果。具体的，请参阅图1、图2、图3和图4，本发明提供一种划桨脚踏自行车，包括自行车本体、划桨动力系统4和转向系统5。其中，自行车本体与现有自行车结构基本无异，包括车架1、车轮(前轮61和后轮62)、车把53、坐垫21和脚踏动力系统(即驱动(传动或行走)系统)。车把53(请参阅图6)和坐垫21(请参阅图5)在后续会因为结构需要进行位置调整，后续记载会详细说明。
划桨动力系统4是本技术方案的核心技术，其通过划桨动作来为自行车提供驱动的动力；所以其需包括往复划桨组件和单向传动组件，往复划桨组件的作用是将骑行人划桨动作转化为动力输出，单向传动组件的作用是将往复划桨组件的往复动作进行单向拆解输出，比如在骑行人作出往后划桨动作时进行动力输出，往前复位时则不影响动力输出。
请对比图1和图3，图1和图3是划桨往后拉和向前推的两个动作状态图，以此理解本发明的划桨动力系统4的动作模式。
为实现划桨动作对自行车进行动力输出，请参阅图1～图4并结合图8～图10，往复划桨组件至少包括第一摆杆42和第一齿轮43，第一齿轮43安装于车架1，第一摆杆42的底端安装于第一齿轮43的轴心处，实现第一摆杆42的摆动而带动第一齿轮43的转动即可。
车把53安装在第一摆杆42的顶端方便骑行者握持和进行划桨动作，在本实施例中第一摆杆42优选为双排杆或者U型杆，第一齿轮43通过安装轴安装在车架1上，双排杆或者U型杆固定于安装轴的两端，使得结构更加对称，而划桨动作更加平稳。
上述划桨动力系统4是通过往复摆动第一摆杆42来提供第一齿轮43的往复自转。单向传动组件连接第一齿轮43和脚踏动力系统3将第一齿 轮43的单方向自转转化为脚踏动力系统3的动力。具体的，当骑行者将第一摆杆42往后拉动做出划桨后拉的动作时，第一齿轮43随之转动，从而单向传动组件则将这一转动传动于脚踏动力系统3的牙盘31，从而脚踏动力系统3则驱动后轮62进行转动；而骑行者将第一摆杆42往前推动复位时，因为单向传动组件是单方向传动的，则不会影响到脚踏动力系统3，如此往复进行则可以一直通过划桨动作来提供自行车的前行动力。
为进一步详述单向传动组件的作用，请结合图2、图4、图5、图9和图10和图11，单向传动组件包括第一单向飞轮44、第二单向飞轮47和第一传动链条45。第一单向飞轮44与第一齿轮43啮合，第二单向飞轮47安装于车架1的中轴34并联动脚踏动力系统3，第一传动链条45安装于第一单向飞轮44和第二单向飞轮47。
具体的，请查阅图10和图11，第一单向飞轮44的内圈固定连接有转轴441，该转轴441上设有齿槽，该齿槽是与第一齿轮43相互啮合的，而第二单向飞轮47的内圈安装于车架1的中轴上，第二单向飞轮47的外圈固定于脚踏动力系统3的牙盘31，第一传动链条45安装于第一单向飞轮44的外圈和第二单向飞轮47的内圈。
请查阅图10和图11，图10中车架1上安装有齿轮箱41，第一齿轮43和第一单向飞轮44安装于齿轮箱41。具体的第一单向飞轮44的外圈外露于齿轮箱41，方便与第一传动链条45安装。图11的附图视角是图10的相反视角，旨在于详细表达齿轮箱内结构。
请参阅图图1、图3，并结合图9、图10和图11，当第一摆杆42向后拉动时，第一齿轮43逆时针转动，从而带动与第一齿轮43啮合的第一单向飞轮44顺时针转动；进而带动与第一单向飞轮44通过第一传动链条45传动的第二单向飞轮47顺时针转动，因为牙盘31是固定于第二单向飞轮47的，所以牙盘31顺时针转动，最后通过第二传动链条32带动后轮62顺时针转动，实现后轮62的转动前进。当第一摆杆42向前推动复位时，因为第一单向飞轮44是单向传动，所以第一单向飞轮44的内圈并不传动外圈，进而也不会使得后轮62反向转动。
请查阅图6，为了进一步地配合划桨动作，或者说为了在划桨动作时既锻炼上肢力量也锻炼到腰部力量，本发明对坐垫21进行结构创新，本发明还包括一往复滑轨组件，坐垫21安装于往复滑轨组件上，往复滑轨组件包括滑轨22、滑座23、滚轮24和锁键25。滑轨22设于车架1上， 具体地，滑轨22是设于车架1的立管14上(请结合图1所展示)，并通过斜支撑15来进行结构加强，滑轨22水平设置为最佳。滑轨22的两侧设有滑槽221，滑座23通过滚轮24安装于滑槽221内实现来回滑动，而坐垫21则设于滑座23上。在划桨动力模式中，骑行者坐在坐垫21上进行划桨运动，坐垫21的往复运动配合骑行者实现腰部的锻炼，而且大腿在划桨动作中也可以锻炼到。在切换到普通骑行模式时，需要对第一摆杆42和坐垫21进行位置固定，此处先描述坐垫21的固定，坐垫21是通过锁键25来实现固定的，锁键25设于滑座23用来锁止/解锁滑座23的滑动。需要注意的是，坐垫21在滑轨22上的往复滑动方向与划桨动作的往复划桨方向一致。
而划桨动力模式和普通骑行模式的切换是通过自锁组件46来配合实现的，请查阅图4、图9、图10和图11，图4中锁绳465是一根完整的绳，只是因第一摆杆42的视线阻挡，在视觉上没有完整体现。自锁组件46包括锁绳465、棘爪462、扭簧463和固定扣，棘爪462通过安装轴461和扭簧463安装于划桨脚踏自行车上，在优选实施例中，棘爪462安装于齿轮箱41内，棘爪462通过扭簧463形成一个以安装轴461为支点的杠杆结构，扭簧463使得棘爪462的转动带有复位功能，棘爪462的第一端卡止于第一齿轮43实现第一齿轮43的位置固定，而第一摆杆42与第一齿轮43固定连接，则间接地固定了第一摆杆42的位置。因为棘爪462和安装轴461形成杠杆结构，扭簧463又带有复位功能，棘爪462的第一端可卡止于第一齿轮43，第二端连接有锁绳465，锁绳465的另一端安装于车把53上的固定扣，通过转动固定扣实现锁绳465的拉紧，从而改变棘爪462是否卡止于第一齿轮43。
优选的，请查阅图11，为了更好地配合安装，棘爪462通过安装轴461安装于齿轮箱41，在棘爪462的一端设有供锁绳465连接的连接环464。锁绳465的原理也同理于刹车线，包括线管和线绳4651，线管的两端分别固定于齿轮箱41(或者车架1)和车把53，线绳4651穿设于线管中，线绳4651的两端分别连接于固定扣和棘爪462上的连接环464，实现对棘爪462的控制。
在本实施例中，未予以固定扣的具体图示，因在实际操作中，固定扣通过车把的左把手上的变速器改造，只需要达到拉紧/松开锁绳的线绳效果即可。即线绳4651连接于左把手上的变速器466，变速器466顺时针转 动则拉紧线绳4651，逆时针转动则松开线绳4651。如图7所示，锁绳465的线管连接于原本连接变速线的变速器466，线绳4651被变速器466控制即可完成对自锁组件棘爪462的控制。
在实际的划桨运动中，运动者的腿部一般都伸展向前，为了更加符合划桨动作的肢体位置，在车架1的靠近前轮61处(即头管12或者前叉11)设有搁脚板56，来方便划桨动力模式时，脚的踩踏和用力。在本实施例中，如图1和图2所示，搁脚板56设于头管12处。
搁脚板56的结构与自行车脚踏的结构相同，旨在于能够自由转动地配合脚部踩踏用力。
本实施例通过划桨动力系统4的往复划桨组件和单向传动组件与脚踏动力系统3进行动力联动输出，将传统的脚踏式骑行改为划桨式骑行，配合坐垫21可往复滑动地安装于滑轨22上来达到一个划桨运动的效果，可以同时锻炼上肢和下肢的效果。能够配合坐垫21的来回滑动带动腰部的扭动进行腰部和背部等上肢体的锻炼，并且腰部的扭动也带动了腿部的伸缩锻炼，进一步的手配合划桨动力系统4做出划桨动作，能够锻炼上肢手和臂膀，从而起到锻炼全身的作用，相比于传统的自行车和其他改进的自行车，主要能对腰背进行锻炼，使得本方案具有很大的不同和效果。
在本发明中车把53安装于第一摆杆42上，所以原有自行车的转向系统不能控制头管12和前叉11。本发明给出了新的是技术方案来克服这一问题，且取得良好效果。
请参阅图1、图3并结合图7和图8，本发明的转向系统5包括左控制线和右控制线，左控制线连接于车头碗组13的左侧和前叉11左侧；右控制线连接于车头碗组13的右侧和前叉11右侧。左控制线和右控制线分别联动车头碗组13和前叉11，当转动车把53的时候，车头碗组13一并转动，前叉11对应进行转动，从而带动前轮61转向。
进一步的，左控制线和右控制线也应用了自行车刹车线的原理。具体的，左控制线包括左控制线管57和左控制线绳571，左控制线管57的两端固定于划桨脚踏自行车上分别靠近前叉11左侧和车头碗组13，左控制线绳571穿设于左控制线管57内，左控制线绳571的两端分别连接于前叉11左侧和车头碗组13左侧。
右控制线包括右控制线管55和右控制线绳551，右控制线管55的两端固定于划桨脚踏自行车上分别靠近前叉11右侧和车头碗组13，右控制 线绳551穿设于右控制线管55，右控制线绳551的两端分别连接于前叉11右侧和车头碗组13右侧。
左控制线管57和右控制线管55的存在可以使得左控制线和右控制线不用处于拉直状态来实现车头碗组13和前叉11的同步转向。
请参阅图7和图8，并结合图1和图2，为了方便左控制线和右控制线的布线安装，转向系统还包括第一轮盘51、第二轮盘52和变向滑轮组。通过第一轮盘51、第二轮盘52和变向滑轮组来完成左控制线和右控制线的安装，具体的，第一轮盘51设于前叉11处，具体的设于前叉11中间并与车架1的头管12安装，从而第一轮盘51的转动带动头管12的转动，且带动前叉11的转动。
车架1的车头碗组13连接于第一摆杆42顶部，第二轮盘52设于车头碗组13处，变相滑轮组设于第一摆杆42顶部。左控制线管57和右控制线管5固定于变相滑轮组。左控制线绳571和右控制线绳551分别通过第一轮盘51、第二轮盘52和变相滑轮组实现布线变向。
请查阅图7，变相滑轮组包括外壳54、左滑轮541和右滑轮542，外壳54固定于第一摆杆42的顶部，车头碗组13连接于外壳54，左控制线管57的一端固定于外壳54，左控制线绳571进入外壳54并套在左滑轮541后从外壳54伸出固定连接于第二轮盘52的左侧。同理，右控制线管55的一端固定于外壳54，右控制线绳551进入外壳54并套在右滑轮542后从外壳54伸出第二轮盘52的右侧。需要注意的是，左控制线绳571和右控制线绳551是固定连接于第一轮盘51和第二轮盘52的，方便左右拉动第一轮盘51。优选的，第一轮盘51和第二轮盘52的尺寸一样大，当车把53转向的时候，第二轮盘52设于车头碗组13上随车把53同向转动，从而带动左控制线绳571和右控制线绳551来拉动第一轮盘51的同步转向，第一轮盘51与头管12连接从而带动头管12上的前叉11转向，最后实现前轮61的转向。
需要注意的是，本发明中锁绳465、左控制线和右控制线都采用了自行车的刹车线原理，外层线管在两端固定后中间可以自由弯曲布置，可以适应车把随着划桨摆杆的位置变动，而内部的线绳则起到控制的作用。
本发明的骑行操作如下：
一、普通骑行模式，首先调整第一摆杆42的位置，按动固定扣拉动 锁绳，将棘爪462扣在第一齿轮43上，对第一摆杆42进行位置固定，同时也固定住了车把53的位置；然后调节坐垫21在滑轨22上的位置，调整到合适位置之后，通过锁键25锁定位置。完成以上调节后即可对脚踏33施力进行普通骑行，在骑行过程中通过本发明的转向系统进行转向调节。
二、划桨动力模式，按动固定扣松动锁绳465，棘爪462因扭簧463复位而离开第一齿轮43，然后解除锁键25控制，骑行者脚自然伸展并踩踏到搁脚板56上，以划桨姿势向后拉动车把53，与车把53间接固定的第一摆杆42向后摆动，当第一摆杆42向后拉动时，第一齿轮43逆时针转动，从而带动与第一齿轮43啮合的第一单向飞轮44顺时针转动；进而带动与第一单向飞轮44通过第一传动链条45传动的第二单向飞轮47顺时针转动，因为牙盘31是固定于第二单向飞轮47的，所以牙盘31顺时针转动，最后通过第二传动链条32带动后轮62顺时针转动，实现后轮62的输出前进。当第一摆杆42向前推动复位时，因为第一单向飞轮44是单向传动，所以第一单向飞轮44的内圈并不传动外圈，进而也不会使得后轮62反向转动。如此往复循环运动即可，并且也是通过本发明的转向系统完成转向操控。
与现有技术相比，本发明的有益效果为：
本发明具有两种动力模式，普通动力模式可以锻炼下肢力量，而划桨动力模式可以锻炼到上肢、腰部及大腿的力量，通过本发明可以起到锻炼全身的效果；
本发明的趣味性强，骑行模式不单一，相比于传动的自行车骑行模式过于单一，没有什么趣味性。
以上结合附图实施例对本发明进行了详细说明，本领域中普通技术人员可根据上述说明对本发明做出种种变化例。因而，实施例中的某些细节不应构成对本发明的限定，本发明将以所附权利要求书界定的范围作为本发明的保护范围。
