具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例1：
如图1所示，本发明实施例1提供了一种发动机和电机动力耦合机构，包括发动机1、电机7、单向离合器13、制动器4、闭锁离合器5、行星齿轮机构6和自动变速器9，所述行星齿轮机构6为单行星轮齿轮机构，包括齿圈61、行星轮62、太阳轮63和行星架64，所述行星轮62通过轴承支撑在所述行星架64上，所述行星轮62一端与所述齿圈61啮合，所述行星轮62的另一端与所述太阳轮63啮合，所述行星架64与所述输入轴8连接。
所述发动机1通过输出轴2和单向离合器13与齿圈连接轴10连接，所述齿圈连接轴10与所述齿圈61连接，所述制动器4的主动端固定在壳体12上，所述制动器4的被动端分别与所述输出轴2和单向离合器13连接。
所述电机7的转子71通过太阳轮连接轴11与所述太阳轮63和所述闭锁离合器5连接为一体；所述行星齿轮机构6用于耦合所述发动机1和电机7的动力通过所述行星架64和输入轴8与所述自动变速器9连接。
具体地，所述输出轴2与所述制动器4之间还设置有减震组件3，所述减震组件3一端与所述输出轴2连接，另一端与所述制动器4的被动端连接，所述减震组件3用于降低发动机振动危害。由于发动机在燃料燃烧时引起的冲击和往复运动的惯性力会产生复杂的振动情况，不仅会损坏汽车本身的零部件、恶化工作性能乃至缩短汽车的使用寿命，还会严重影响其他车载设备仪器的正常工作，降低舒适性，因此需要减轻发动机的振动危害。所述减震组件3用于连接发动机1的输出轴2和行星齿轮机构6之间的动力传递，减震组件3中设置有用于缓冲减震的弹簧，通过减震组件可以有效的将发动机振动控制在一定范围内。
具体地，所述齿圈连接轴10一端与所述单向离合器13连接，所述齿圈连接轴10的另一端分别与所述齿圈61和闭锁离合器5的被动端连接为一体，同轴旋转。在本发明实施例中，所述单向离合器13由外环、内环和楔块组成，当它的内环固定时，外环可以沿顺时针方向自由转动，如果外环沿相反方向转动时，外环将被锁住，所述单向离合器13用于通过减震组件3将所述齿圈连接轴10与所述输出轴2连接。
具体地，所述输出轴2与所述输入轴8同轴设置。所述电机7还包括定子72，所述转子71同轴设置在所述定子72内，所述定子72固定在壳体12上。在本发明实施例中，所述输出轴、电机、行星齿轮机构与输入轴均布置在同一轴线上，行星齿轮机构可以设置在电机转子的内部空间内，有利于整个机构轴向结构的高度集成，节约空间和提高系统密封性。
具体地，所述自动变速器9为无变扭器自动变速器或无级变速器。
本发明动力耦合机构可以实现三种行驶模式，每种模式都可以实现自动变速器的多档位行驶。
假设输入轴8的转速为N1，太阳轮连接轴11的转速为N2，齿圈连接轴10的转速为N3，齿圈61齿数/太阳轮63齿数＝K，那么，该机构的三个工作模式数学模型如下：
(1)电机驱动模式。控制制动器4接合，齿圈连接轴10闭锁不转，电机7驱动太阳轮连接轴11和太阳轮63旋转，通过行星架64减速输出电机动力。
N2+K*N3-(K+1)*N1＝0；
N3＝发动机转速＝0；

实施例3：
如图3所示，本发明实施例3与实施例1的区别在于，所述齿圈连接轴10一端与所述齿圈61连接，所述齿圈连接轴10的另一端通过所述单向离合器13与所述制动器4的被动端连接为一体，所述齿轮连接轴10还与所述闭锁离合器5的主动端连接，所述太阳轮连接轴11分别与所述闭锁离合器5的被动端和所述转子71连接为一体。具体地，实施例1中闭锁离合器5和电机7设置在所述行星齿轮机构6的左侧，实施例3中闭锁离合器5和电机7设置在所述行星齿轮机构6的右侧。左右侧以说明书附图中方向为依据。
实施例4
如图4所示，本发明实施例4与实施例1的区别在于，所述齿圈连接轴10一端与所述齿圈61连接，所述齿圈连接轴10的另一端通过所述单向离合器13与所述制动器4的被动端连接，所述行星架64一端与所述输入轴8连接，所述行星架64的另一端分别与所述行星轮62和所述闭锁离合器5的被动端连接。具体地，实施例1中闭锁离合器5和电机7设置在所述行星齿轮机构6的左侧，实施例4中闭锁离合器5和电机7设置在所述行星齿轮机构6的右侧。
以上所述是本发明的优选实施方式，应该指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
