以下结合附图，详细说明本发明各实施例提供的技术方案。
实施例1
根据图1示出的换档驻车结构的示意图，所述变速器换档驻车结构包括旋转驱动机构1、换档转臂2、拨叉3、换档执行机构、驱动导轴4、驻车转臂5和驻车推杆组件6和驻车执行机构，其中旋转驱动机构1优选为电机；所述旋转驱动机构1用于驱动所述驱动导轴4旋转；所述换档转臂2一端和所述驻车转臂5一端固定比如焊接在所述驱动导轴4上，并随所述驱动导轴4旋转。
所述换档转臂2另一端设置有圆柱销21，所述圆柱销21随着所述换档转臂2的旋转沿所述拨叉3上设置的拨叉型线槽31移动并带动所述拨叉3移动，参见图3(a)-(d)所示，所述拨叉型线槽31上设置多个与档位I、II、P和N对应的位置，当所述圆柱销21到达各所述位置时，所述拨叉3驱动所述换档执行机构很容易实现换档动作。
所述驻车转臂5的另一端与驻车推杆组件6铰接，比如可通过销轴与孔间隙配合的方式将驻车转臂5与驻车推杆组件6连接在一起。所述驻车推杆组件6随着所述驻车转臂5的旋转带动所述驻车执行机构实现驻车动作。
在一个优选的实施方式中，结合图2(a)-(b)，其中图2(a)是拨叉的侧视图，图2(b)是拨叉主视图，所述拨叉包括线槽设置部32和拨动部33，所述拨动部33固定连接在所述线槽设置部32的下部，且所述线槽设置部32所在的平面与所述换档转臂2所在的平面平行，所述拨动部33所在的平面与所述线槽设置部31所在的平面垂直。
进一步地，所述换档执行机构还包括同步器齿套10，所述同步器齿套10外圈设置有环形槽101，所述拨叉的拨动部33设置在所述环形槽101中，且与所述环形槽101间隙配合。
在一个实施方式中，所述换档执行机构包括拨叉轴9，所述拨叉轴9用于对所述拨叉3的移动导向，所述拨叉3滑动连接在所述拨叉轴9上或固定在所述拨叉轴9上，所述拨叉轴9连接在变速器的壳体上。
结合图4-图5所示，拨叉型线槽31上依次设置有II档、N档、I档以及P档位置，其中，I档、II档为速度不同的前进档，P档为驻车档，N档为空挡；且所述P档位置处所述拨叉型线槽的宽度小于等于所述圆柱销的直径。换档转臂2上的圆柱 销21不会推动拨叉3沿拨叉轴9轴线方向移动，此时驻车转臂5的转动会带动驻车推杆组件6移动，驻车推杆组件6将棘爪7压入驻车齿轮8齿槽内完成驻车动作。由此，驻车动作和换档动作独立实现，当进行驻车动作时，换档不动作，当换档动作时，驻车不动作。
在一个优选实施方式中，所述驻车推杆组件包括第一细长杆61、弹簧62和第二锥形杆63，所述第一细长杆61活动套设在所述第二锥形杆63的孔内，所述弹簧62套设在所述第一细长杆61上，所述弹簧62的一端可活动限位在所述第一细长杆61的中部，另一端固定连接在所述第二锥形杆63上。所述弹簧62在驻车过程中可以起到缓冲以及复位的作用。
其中，驻车执行机构包括棘爪7和驻车齿轮8，所述棘爪7一端靠近所述驻车齿轮8一侧设置有凸齿，当所述驻车转臂5旋转到驻车位置时，通过所述驻车推杆组件6的第二锥形杆63的挤压后将所述棘爪7的凸齿压入所述驻车齿轮8。
在具体装配时，可将所述棘爪另一端活动连接在所述变速器的壳体上。
实施例2
实施例2公开了一种新能源汽车，该新能源汽车采用了实施例1中的换档驻车结构。需要说明的是，新能源汽车的倒车是通过反转主电机实现的。
以上所述仅为本发明的实施方式，并非用于限定本发明的保护范围。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、扩展等，均包含在本发明的保护范围内。
