具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
如图1所示，本发明一实施例提供了一种电动自行车五通，其包括内壁为圆筒状的本体1，内壁的两个端部的直径小于内壁中部的直径，使内 壁的中部周向的形成一走线槽2，两个端部分别形成一挡圈3，即该走线槽2设置在本体1的内侧圆周面上，挡圈3在走线槽2的两侧自然形成；本体1上还开设有连接孔4，所述连接孔4连通所述走线槽2和所述本体1的外壁。本实施例通过在五通内部设置环形的走线槽2和连接孔4，实现电机电源线和信号线在自行车五通处的隐藏化，有效避免电机线的过度磨损，延长电源线和信号线等的使用寿命。
在上述实施例的基础上，本发明的又一实施例中，上述的连接孔4根据电动自行车的结构需要，设置为两种，共三个，具体地，如图1和图4所示，一种为与车架下管9相连通的下管连接孔41，以及另一种为与车架后叉管10相连通的后叉连接孔42，其中，由于车架下管9只有一个，因此只设计一个下管连接孔41，通常根据自行车下管9的形状来确定该下管连接孔41的结构，通常设置为圆型；而电动自行车的车架后叉管10一般为两个，因此在该五通上开设两个后叉连接孔42，用于分别与两个车架后叉管10连通。通过下管连接孔41和后叉连接孔42的设置，可以让电源线和信号线等，通过该连接孔4排布在下管9、五通以及后叉管10内，避免各种导线等外露。
本发明的另一实施例中，与上一实施例不同，后叉连接孔42设置在车架后叉管10的下方，不与后叉管10的管内连接，这种设置情况下，信号线、电源线等可以由后叉连接孔42引出，并使其沿着后叉管10，在后叉管10的下方走线。
作为上述实施例的优选，本发明提供的一实施例中，如图1，图2，图4所示，五通上还设置有压紧机构，所述压紧机构包括设置在本体1内壁上的压块槽51、与所述压块槽51相配合的压块52、以及顶紧装置54；所述压块槽51内设置有顶紧孔53，所述顶紧孔53贯穿所述本体1的内壁和外壁，所述顶紧装置54穿过所述顶紧孔53顶紧在所述压块52上。通过压紧机构，将电机紧固在五通内，具体地，通过顶紧装置54将压块52顶紧在电机上，保证电机稳定运行。
优选地，所述顶紧装置54为顶紧螺丝，所述顶紧孔53为与所述顶 紧螺丝相适应的螺孔。进一步优选地，所述压块槽51连通所述本体1的两端部，且与所述本体1的中心轴线平行；如图2所示，所述压块52长度与所述本体1的高度相同，所述压块52不与压块槽51相对的一侧设置为圆弧面，所述圆弧面与置于所述本体1内的电机外壁贴合设置。通过旋拧顶紧螺丝，推动顶紧螺丝另一侧的压块向远离压块槽的方向移动，从而使压块与中置电机的外壁之间距离不断缩小，直至压块52与电机外壁之间产生一适当的作用力，使电机在五通内不会发生晃动，且可以方便电机的拆卸维修。
如图5至图7所示，作为上述实施例的优选，挡圈3的内径与安置于本体1内的电机端盖的外径相适应，挡圈3的内侧直径可以设置为与安置于其内的电机外径相同或者略宽，以保证中置电机与五通的相互匹配，具体地，电机本体的外径与五通的挡圈3的内径之间相差为0.2-1毫米时，间隙配合效果较好，电机和压块52可以正常的插入和锁紧。
如图1所示，在上述任一实施例的基础上，为防止意外进水或后叉走线孔设置在外侧时可能导致的雨水进入，在五通的走线槽2内设置有消水孔6，所述消水孔6贯穿所述走线槽2底部和所述本体1的外壁，安装于电动自行车上时，消水孔6位于本体1的重力方向的最下端。以使在走线槽2内进水后，水分可从消水孔6流出，避免内侧积水，该设计使得电线走线内置，避免了外置电线导致的磨损，并进一步提高了电气防水性能。
进一步地，该五通上还设置电机线槽7，以方便电机线的通过，电机线槽7贯穿一侧挡圈3，一端与所述走线槽2连通，另一端连通至所述挡圈3的端部。
如图3所示，本发明提供的电动自行车五通使用的电机为侧出线电机，以配合五通内走线需求，具体地，该侧出线电机包括电机本体和电机端盖8两部分，电机端盖8设置在电机本体一侧，电机端盖8与电机本体同轴布置，且电机端盖8的外径大于电机本体的外径，电机端盖8与电机本体连接处设置有一走线孔，电机线11从走线孔内引出电机，电 机线11的走线方向为从电机端盖8向电机本体一侧走线，电动自行车五通的本体1内侧的挡圈3上设置的电机线槽7与此对应，电机线11设置在本体1一侧的挡圈3上，电机线槽7与走线槽2连通，电机线槽7的宽度略宽于电机线11的总宽，使得电机线11可通过电机线槽7进入走线槽2内，方便电机的安装，并保证电机线走线隐藏在电机端盖8和五通内，从而保证电机线的安全性。
优选地，五通的本体1的尺寸与电机端盖8外径相同，五通的本体1的高度与电机本体的高度相同，在电机装入五通后，使得五通与电机端盖8紧密配合构成一整体，使得车架与电机紧密契合，有效提高车辆外观一致性。
作为上述实施例的优选，本发明提供的五通的连接孔4为圆孔或长条孔；且所述连接孔4的设置可以有多种方式，连接孔4的中心线可以与所述内壁的径向线重合，或所述连接孔4的中心线与所述内壁的径向线成角度设置。
具体地，当连接孔4的中心线与所述内壁的径向线成角度设置，即连接孔4为斜孔时，连接孔4可设置成圆孔，此时，连接孔4的轴线与五通本体1的径向成一定角度。在一较佳实施例中，连接孔4与五通本体1的走线槽内侧相切布置，走线更顺畅；此外，在连接孔4倾斜布置时，也可将连接孔4开设成长条孔。当连接孔4的中心线可以与所述内壁的径向线重合，即连接孔4为直孔，连接孔4也可设置成圆孔或长条孔；连接孔4为直孔时，由于下管孔41孔径较大，可将下管孔设置成圆孔，后叉连接孔孔42径小，应设置成长条孔，以避免线材弯折半径过小，角度过大而造成线材损坏，有效降低生产成本，保证使用寿命。
如图4所示，本实施例中，五通的走线槽2不仅仅用于电机的走线，同时也可用于传感器信号线12等线路的安装走线，使信号线等线路也处于隐藏的保护之中。
具体安装方式为：将传感器和显示器的信号线12从车架的下管9前端穿入，并通过五通的下管连接孔41进入走线槽2，沿走线槽2布线后 再通过后叉连接孔42进入车架后叉管10，并在靠近传感器安装处穿出。电机线11先从下管连接孔41内穿过，并与设置在下管9内的电机连接线连接，随后将电机对准五通插入，并使得五通的电机线槽7对准电机的侧边出线口，随后将导线沿着电机外壳弯折，并将电机完全插入五通内，其余线缆也沿着电机外壳弯曲布置，避免对电机安装形成干涉，随后，将压块52插入压块槽51内，并在顶紧孔53内旋入螺丝或顶丝，使得螺丝或顶丝能顶紧压块52并依靠压块52固定住电机，保证电机的稳定性和走线的隐蔽性。
上述实施例中，由于走线槽2为环形，压块52在固定电机时会挡住部分的走线槽，因此。信号线的走线只能从电机一侧通过，如图4所示，其中电机线弯折后沿着走线槽2走线并通过下管连接孔41进入下管9，信号线等从下管的龙头处穿入并通过下管连接孔41进入五通，沿着走线槽走线后，从后叉连接孔中穿出，进入后叉管10或沿着后叉管10下方隐蔽走线。完成安装。
本发明提供的电动自行车五通，其本体的外侧可以设置成倒角的结构，在设置倒角的情况下，为了保证电机走线槽的强度，以及走线的方便性，倒角可以在电机走线槽的两侧开始，即倒角避开电机走线槽的外侧。当然在保证电机走线槽强度的前提下，为提高外观的一致性，也可以将五通本体的外侧整体进行倒角处理，电机与五通安装完成后一致性更好，电动自行车的行驶稳定性和驾驶体验更好。
采用上述技术方案，本发明通过在五通内部设置走线槽，实现电机电源线和信号线在自行车五通处的隐藏化；通过设置连接孔，实现电机电源线和信号线等在车架下管和车架后叉处的隐藏化，避免电源线和信号线外露；通过压块及压块槽的设置，保证电机在五通内安置的稳定性；通过设置消水孔，使进入走线槽内的水分等顺利流出，减小水分等液体对电源线和信号线等产生的损耗；通过对连接孔形状和角度的具体设计，使得走线可以顺着走线槽弯曲，避免普通直孔产生的导线弯曲半径过小，而造成的不易装配和应力损坏，从而大大延长使用寿命。
综上所述，本发明所提供的电动自行车五通，可以广泛地应用于电动自行车，实现电动自行车电源线和信号线等的隐藏化，提高电动自行车的使用寿命和骑乘体验。另外，上述的实施例可以通过采用不同的组合方式来实施本发明，如电机可以采用同心同轴安装或者一侧安装，减速机构可以通过行星轮减速或者其他齿轮、链条减速结构，中轴可以采用单轴结构或者左右轴结构，传感器可以采用各种扭矩传感器或者速度传感器等等。
以上所述实施例仅表达了本发明的实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
