本发明涉及三轮车领域，尤其涉及一种易装配的摇摆式三轮车。
背景技术
脚踏式三轮车是日常生活中较为常用的轻便交通工具，具有与自行车相同的轻便型，同时能够装载更多的物品。随着技术的进步，为了节省骑车人的体力，出现了电动助力式的三轮车，主要依靠曲柄轴处的扭力传感器检测到曲柄轴转动的信号，随后控制器控制电机为三轮车的驱动轮提供动力，从而节约骑车人的体力。该种助力式的三轮车与电摩式三轮车具有本质上的区别，如控制电机转动的方式不同，电动助力式的三轮车没有在车把上设置油门，骑行人通过脚踏驱动曲柄轴，曲柄轴触发扭力传感器，从而通过控制器控制电机驱动三轮车的驱动轮，安全性更加可靠。
目前三轮车拐弯容易翻车的原因主要是因为三轮车拐弯时，其重心会转移至前轮与拐弯时的外侧后轮之间，在离心力的作用下，车子就非常容易发生倾斜、翻车。因此，市场出现了带有摇摆机构的三轮车，并且采用后轮单边传动；其主要结构包括前车架、后车架以及设在所述前车架和后车架之间的摇摆机构，通过摇摆机构使得前车架相对于后车架水平不动的情况下可以在一定的范围内摆动，并自动归位。这种三轮车在拐弯时，前车架相对于后侧架可以进行一定角度的径向摆动，将车子的重心往弯道内侧移动，从而使三轮车拐弯时更加平稳、可靠。由于前车架需要摆动，如果采用传统的传动结构，其传动链条会被扭层“8”字形，难以正常骑行。现有的带有摇摆机构的三轮车被设计成多段式传动系统。如图1和图2，三轮车包括前车架101和后车架102，后车架102上设有向下延伸的支撑架1021，支撑架1021上设有摇摆机构111；前车架101与摇摆机构111连接，在前车架101后部一侧设置第一传动链轮103，在后车架102的前部的另一侧设置第二传动链轮104，第一传动链轮103和第二传统链轮104相对设置并通过一多级万向节105连接，第一传动链轮103通过第一链条106与前车架101 曲柄轴上的驱动链轮107传动连接；第二传动链轮104通过第二链条108与其中一个后车轮110上的后链轮109传动连接。前车架101通过摇摆机构111发生倾斜时，第一链条106、第一传动链轮103、驱动链轮107均随之倾斜，多级万向节105发生形态变化，以保证第二传动链轮104不受前车架101倾斜带来的应力；保持动力正常传输。但是上述技术方案中，动力需要经过第一链条106、第一传动链轮103、多级万向节105、第二传动链轮104、第二链条108、后链轮109才能到驱动后车轮110转动，属于多级传输，传统系统较为复杂，传动零部件数量多，而且这些安装在车架外侧上的传动零部件，要么采用链条连动、要么万向节连动，需要要车子装配好之后进行调整，因此难以在装箱之前实现预装，使得该种三轮车拆箱后的装配过程非常复杂，尤其是对于动手能力差的消费者，装配上述传动系统是一个很大的挑战。同时上述现有技术中的后车架结构导致其最顶面与最底面之间的跨度较大，而且是一体结构，装箱时所占空间较大，导致产品的包装体积整体增加，使得该产品的运输成本较高。

具体实施方式
参见图3至图5、图11至图16，按照发明提供的易装配的摇摆式三轮车实施例，包括车架总成、设在所述车架总成上的车轮架4、设在所述车架总成内的传动腔和设在所述传动腔内的传动机构；所述车轮架4上对称设置有两个后车轮51(附图中的后车轮为结构示意图)，所述车架总成上设有前车轮52(附图中的前车轮为结构示意图)；所述车架总成包括前车架1、摇摆机构3和齿轮箱2，所述前车架1通过所述摇摆机构3与所述齿轮箱2连接，所述齿轮箱2与所述车轮架4连接，所述传动机构包括设在所述齿轮箱2上的驱动轴721，所述驱动轴721与两个后车轮51中的至少一个连动配合。还包括车座、设在曲柄上的脚蹬等部件，均是三轮车上的现有技术，此处不再详细赘述。上述结构通过将传动机构设在车架总成内的传动腔中，使得传动机构无需搭设在车架外部，产品结构更加紧凑，外观干净利落，传动机构也不会与外部发生干涉、挤压、钩扯等情况；该在结构使得产品装箱运输前传动机构就可以预装在传动腔内，缩减消费者的组装程序；消费者购买本产品后只需将车轮架4安装在车架总成上，然后将各车轮进行安装，将驱动轴721与后车轮51连接即可完成装配，大大简化了产品的组装过程，对于动手能力差的人也没有组装难度；同时车架总成上的齿轮箱2与车轮架4连接，与现有技术相比，车轮架4无需设置向下延伸的支撑架去连接摇摆机构3，使得车轮架4的结构更加平整，缩小了装箱时的占用空间，降低了运输成本。
参见图3至图5，根据发明上述的实施例，所述车轮架4包括框架41、对称设在所述框架41上的两个车轮安装件42、设在所述车轮安装件42上的车轮传动轴43，所述后车轮51设在所述车轮传动轴43上，所述驱动轴721至少与一个车轮传动轴43连接。上述车轮架4结构简单，并且后车轮51通过车轮架4上的车轮传动轴43被连动实现转动，与现有技术在后车轮51的花鼓上设置链轮，并通过链条带动花鼓沿轴转动相比，省去了花鼓上的链轮、链条的装配，大大简化了后车轮51的安装过程。
参见图4至图6，根据发明上述的实施例，所述车轮安装件42上设有刹车片机构44，所述后车轮51上设有刹车鼓511或刹车盘，所述刹车片机构44与所述刹车鼓511或刹车盘配合。无论与刹车鼓511配合的刹车片机构44还是与刹车盘配合的刹车片机构44，均是现有技术中较为成熟的技术，此处不再详细赘述。本实施例优选在后车轮51上设置刹车鼓511，本发明采用上述刹车片机构44，再次简化的后车轮51的装配过程，提高了后车轮51的装配效率，同时提高了产品的安全性、可靠性。

参见图4和图5，根据发明上述的实施例，所述驱动轴721通过万向轴组件与所述车轮传动轴43连接。该结构可以有效克服车轮架4生产时的精度误差带来的装配问题，实现车架总成与车轮架4的良性匹配，产品的良品率大大提高。
参见图4、图5、图11和图17，根据发明上述的实施例，所述万向轴组件包括花键轴61、设在所述花键轴61两端的第一万向接头62和第二万向接头63，所述第一万向接头62与所述驱动轴721连接，所述第二万向接头63与所述车轮传动轴43连接；所述第一万向接头62上设有第一花键套621，所述第二万向接头63上设有第二花键套631，所述花键轴61的两端分别于所述第一花键套621和第二花键套631滑动插接配合。上述万向结构组件结构简单、部件少、装配方便；装箱时第一万向接头62连接在传动轴73上，第二万向接头63连接在车轮传动轴43上，消费者开箱后只需将花键轴61的两端分别插入第一花键套621和第二花键套631即可实现驱动轴721与车轮传动轴43之间的连动配合，再次提高了本产品的装配效率及可靠性。
参见图3至图5，根据发明上述的实施例，所述框架41上设有承载板45，所述齿轮箱2与所述承载板45通过螺栓连接。承载板45及可作为框架41与齿轮箱2的连接体，同时也是齿轮箱2的覆盖板，安装后承载板45覆盖在齿轮箱2上，保证了齿轮箱2的封闭性，同时方便了车架总成与车轮架4的组装。
参见图3至图5，根据发明上述的实施例，所述车轮安装件42通过螺栓可拆卸的安装在所述框架41上。上述结构使得车轮安装件42可以实现快速的拆装，使得车轮架4可以进一步进行拆分，更加利于缩小体积进行装箱，节约了产品的运输成本。
参见图4、图7、图8、图9、图10、图13和图16，根据发明上述的实施例，所述摇摆机构3包括第一摇摆件31、第二摇摆件32、连接轴33和弹性块34，所述弹性块34卡装在第一摇摆件31和第二摇摆件32之间，所述第一摇摆件31和第二摇摆件32通过连接轴33可转动的连接，所述第一摇摆件31上设有第一连接部312，所述第二摇摆件32上设有第二连接部3222，所述第一连接部312与所述前车架1连接，所述第二连接部3222与所述齿轮箱2连接。所述前车架1上设有第三连接部13，所述齿轮箱2上设有第四连接部22；所述第一连接部312与所述第三连接部13连接，所述第二连接部3222与所述第四连接部22连接。所述第一连接部312、第二连接部3222、第三连接部13和第四连接部22均为法兰结构。所述连接轴33中部设有传动过孔331。
参见图4、图7、图8、图9、图10、图13和图16，根据发明上述的实施例，所述第一摇摆件31包括摇摆轴311和设在所述摇摆轴311一端的所述第一连接部312，所述第二摇摆件32包括轴套321和套装在所述轴套321上的连接罩322，所述连接罩322上设有所述第二连接部3222；所述摇摆轴311的外壁设有外卡槽313，所述轴套321的内壁设有内卡槽3211；所述摇摆轴311的另一端插入所述轴套321中，所述外卡槽313与所述内卡槽3211相对，所述弹性块34的一端插入所述内卡槽3211，所述弹性块34的另一端插入所述外卡槽313；所述摇摆轴311中部设有第一插孔314，所述连接罩322上设有第二插孔3221，所述连接轴33穿过所述第二插孔3221和所述第一插孔314，将所述第一摇摆件31和所述第二摇摆件32可转动地连接；所述连接轴33的中部设有所述传动过孔331。上述弹性块34可采用橡胶弹性块。上述外卡槽313为多个并均匀设在摇摆轴311的外壁上，上述内卡槽3211为多个并均匀设在所述轴套321的内壁上。所述连接轴33上还设有锁紧螺母332，通过与锁紧螺母322配合将第一摇摆件31和第二摇摆件32可转动的连接。所述连接轴33的外壁与所述第一插孔314的内壁之间设有轴承35。摇摆 机构静止状态时，弹性块34不发生形变，当第一摇摆件31相对于第二摇摆件32发生扭动时，弹性块34中部被挤压变形，随着弹性块34的自动恢复，第一摇摆件31也随之恢复到初始状态。第一摇摆件31和第二摇摆件32沿连接轴33扭动，因此，连接轴33的轴心线为摇摆机构3的轴心线。该摇摆机构3第一连接部312与三轮车的前车架1连接，第二连接部3222与三轮车的齿轮箱2连接，尤其是传动过孔331的设置，可供传动轴73的穿过，使得摇摆机构3和传动轴73两个转动的部件，实现了有机结合，为轴传动的摇摆式三轮车的加工生产，提供了有利条件，有助于简化该种三轮车的传动机构，同时上述摇摆机构，结构简单紧凑、部件少、装配方便，生产成本低。
参见图14至图17，根据发明上述的实施例，所述传动腔包括设在所述前车架1内的轴动腔11和轴动通道12、设在所述摇摆机构3中部的传动过孔331、设在所述齿轮箱2内的齿动腔21；所述轴动腔11、轴动通道12、传动过孔331和齿动腔21依次连通。上述传动腔结构设计巧妙，有效利用了车架的内部空间，采用上述分段式的结构，方便了传动机构的零部件之间的组装。
参见图11至图15，根据发明上述的实施例，所述传动机构包括设在所述轴动腔11内的第一扭矩输出组件71、设在所述齿动腔21中的第二扭矩输出组件72、以及穿设在所述轴动通道12和所述传动过孔331内的传动轴73，所述第一扭矩输出组件71通过传动轴73连动所述第二扭矩传输组件72。所述第一扭矩输出组件71包括可转动地设在所述轴动腔11内的中轴711和后轴712、设在所述中轴711上的前链轮713、设在所述后轴712上的后链轮714和第一锥齿轮715，所述前链轮713和后链轮714通过链条717连动配合，所述传动轴73上设有第二锥齿轮716，所述第一锥齿轮715和所述第二锥齿轮716啮合。所述中轴711的两端设有曲柄719，所述中轴711和后轴712平行设置，所述传动轴73的与所述后轴712垂直。所述第一扭矩输出组件71还包括与所述链条717压紧配合的涨链轮718。涨链轮718的设置可以将松垮的链条717压紧，保证一链条717与多种不同大小链轮的适配性，采用涨链轮718弹性压紧，一是可避免链条717的脱落；二是当后链轮714或前链轮713发生直径变化时，仍旧可以采用原来的链条717，而无需调整链条717的长短。该种第一扭矩输出组件71结构简单、装配灵活，尤其是适用于不同 直径后车轮51的三轮车，当被驱动轮发生直径大小的变化时，只需更换一个适配的后链轮714即可实现速比的调整，而无需对整套第一扭矩输出组件71进行调整，该种结构对于生产多种不同型号的车企来说，减少了零部件的种类，有助于组件流水线的标准化设置，提高生产效率，缩减零部件的研发成本。
参见图15和图19，根据发明上述的实施例，所述第二扭矩输出组件72包括设在所述齿动腔21内的所述驱动轴721，所述传动轴73通过第二齿轮副连动所述驱动轴721，所述传动轴73与所述第二齿轮副之间或者所述驱动轴721与所述第二齿轮副之间设有离合组件，所述驱动轴721与两个后车轮51中的至少一个连动配合。所述第二齿轮副包括啮合的第三锥齿轮723和第四锥齿轮724，所述第四锥齿轮724设在所述驱动轴721上，所述传动轴73通过离合组件连动所述第三锥齿轮723。所述离合组件包括设在所述第三锥齿轮723上的扭矩输入轴722、设在所述扭矩输入轴722上的第一端面棘齿7221、滑动卡装在所述传动轴73上的内花键套725、推动所述内花键套725向所述第一端面棘齿7221贴靠的弹性件726；所述扭矩输入轴722的一端与所述第三锥齿轮723连接，所述扭矩输入轴722的另一端设有所述第一端面棘齿7221，所述传动轴73外壁上设有外花键736，所述内花键套725与所述外花键736滑动卡接配合，所述内花键套725与所述第一端面棘齿7221相对的一端设有第二端面棘齿7251，所述第一端面棘齿7221与所述第二端面棘齿7251配合。所述弹性件726为套装在传动轴73上的弹簧。所述扭矩输入轴722与所述传动轴73相对的一端设有定位插孔7222，所述传动轴73的端部插入所述定位插孔7222。所述第三锥齿轮723、扭矩输入轴722、第一端面棘齿7221为一体成型结构。结构简单、部件少，装配方便，可靠性高，离合组件的设置保证了传动轴73静止状态时，后车轮51仍旧可以向前转动，符合传统传动机构三轮车的骑行习惯。
