图1和图2展示了现有技术当中的一种典型的电起动装置20，装配该电起动装置20的内燃机10可参考图3。为便于叙述，定义电起动装置20中朝向内燃机10的曲轴104的一侧为相对的“内侧”，远离曲轴104的一侧为先对的“外侧”。该电起动装置20包括起动电机24、动力传递机构22和离合机构26。
起动电机24设有电机输出轴242，在电机输出轴242的末端设有电机输出齿轮246。
动力传递机构22包括动力传递组件和储能组件。动力传递组件具体构造为齿轮减速箱，齿轮减速箱具有由减速箱壳体形成的减速箱室，具体地，减速箱壳体由设置在内侧的第一壳体221和设置在外侧的第二壳体223扣合形成。在减速箱室内设有可绕第一齿轮轴2214旋转的第一齿轮224，以及可绕第二齿轮轴2216旋转的第二齿轮226。其中第一齿轮224构造为双联齿轮，包括具有较大直径的第一齿圈2242和具有较小直径的第二齿圈2244，第一齿圈2242与伸入减速箱室的电机输出齿轮246的齿圈啮合，第二齿圈2244与第二齿轮226的齿圈啮合。第二齿轮226构造为具有腔体2264，该腔体2264用于收容储能组件，并具有朝向内侧的开口。储能组件构造为涡簧222，典型地由细长的弹簧材料绕制成的、呈平面螺旋线型的弹簧，其具有远离螺旋线中心的涡簧外自由端和靠近螺旋线重心的涡簧内自由端。涡簧外自由端与第二齿轮226固定连接，具体地，涡簧外自由端构造为第二钩爪2224，相应地，腔体2264的侧壁上设有第二槽部2262，第二槽部2262与第二钩爪2224配合使涡簧外自由端与第二齿轮226固定连接。
离合机构26提供动力的单向传动，典型地构造为棘轮棘爪结构。具体地，离合机构26包括棘爪组件262和棘轮组件264。棘爪组件262与内燃机10的曲轴104固定连接，且棘爪组件262的外侧面设有棘爪部。棘轮组件264与减速箱壳体之间可旋转地连接。具体地，棘轮组件264包括一体设置的棘轮组件外端2642和棘轮组件内端2644。其中，棘轮组件外端2642和棘轮组件内端2644分别设置在第一壳体221的两侧。棘轮组件外端2642与涡簧内自由端固定连接。具体地，棘轮组件外端2642设有第一槽部2642a，相应地涡簧内自由端设有第一钩爪2222，第一槽部2642a与第一钩爪2222配合使涡簧内自由端与棘轮组件固定连接。棘轮组件内端2644设有棘轮部，棘轮部与棘爪部配合实现动力传递机构22与曲轴104之间的单向动力传动。
上述电起动装置20的装配通常是与内燃机10的整机装配同时进行的。在装配涡簧222时，第一步：先将涡簧222收紧安装在腔体2264内，使第二钩爪2224与第二槽部2262配合；第二步，再将装有涡簧222的第二齿轮226、第一壳体221和棘轮组件264安装在一起。这样，涡簧222就被可靠地安装在第二齿轮226和第一壳体221之间。然而，正如本申请背景技术部分提及的那样，在前述第二步没有完成之前，涡簧222在前提2264内沿第二齿轮226轴向方向上是没有可靠的约束的，所以极容易发生涡簧222弹出的危险。
第一实施例。
图3～图7展示了本发明的一具体实施例。由于本发明是在现有技术的基础上做出的创造性的改进，所以在图4～图7中，对于与上述现有技术中相同或相似的部件不再加以区分而采用相同的附图标记。此外， 为了使本说明书更加简要且容易理解，对于本实施例与上述现有技术中相同或相似的结构不再重复地详细阐释。
本具体实施例提供了一种内燃机10，包括机体、活塞、连杆、曲轴104、配气系统、燃料供给系统、润滑系统、冷却系统、点火系统和起动系统，其中起动系统包括电起动装置20。在本实施例中，内燃机10具体为汽油机。在本具体实施例中，参考图3，电起动装置20通过螺栓108固定在机体上，罩106覆盖在电起动装置20的外侧。参考图4～图7，本具体实施例的电起动装置20包括起动电机24、动力传递机构22和离合机构26。
动力传递机构22包括动力传递轮或动力传递轮组，还包括储能组件。在本具体实施例中，动力传递机构22包括齿轮减速箱和储能组件。齿轮减速箱具有减速箱室，减速箱室收容动力传递轮或动力传递轮组。在本实施例中，动力传递轮组构造为包括第一齿轮224和第二齿轮226。第一齿轮224包括第一齿圈2242和第二齿圈2244，第二齿轮226包括腔体2264，腔体2264具有开口。储能组件构造为涡簧222。
动力传递机构22还包括涡簧约束件，涡簧约束件形成对收容在腔体2264内的涡簧222的约束，该约束使涡簧222不能脱离腔体2264。在本具体实施例中，动力传递机构22还包括盖228。该盖228构造为与腔体2264的开口配合，以形成对收容在腔体2264内的涡簧222的约束，该约束使涡簧222不能脱离腔体2264。具体地，盖228与腔体2264之间设有防止盖228脱离腔体2264的接合结构。
参考图8，在一些实施例中，接合结构包括分别设置在盖228周缘上的第一凸部228a和设置在腔体2264周缘上的第一凹部2264a，第一凸部228a构造为可与第一凹部2264a卡接。参考图9，在一些实施例中，接合结构包括设置在腔体2264周缘上的第二凸部2264b，第二凸部2264b构造为可与盖228的周向边缘卡接。
在本实施例中，盖228构造为环形盖板，其中心部分的孔洞利于棘轮组件外端2642穿过。
第二实施例。
参考图9，本实施例与上述第一实施例的区别在于，所述涡簧约束件构造为设置在腔体周缘上的第三凸部2264c。具体地，所述第三凸部2264c朝向所述腔体2264的中心延伸，且设置的数量为至少两个。优选的，至少两个所述第三凸部2264c大致均匀地沿所述腔体2264的周向分布。
不同于上述第一实施例中使用盖228对涡簧222进行限位，本实施例直接使用第三凸部2264c对涡簧222进行限位。具体地，将卷紧的涡簧222置入腔体2264后，涡簧222即行被释放向外扩张，由于腔体2264的限制，涡簧222最外一圈簧体贴紧腔体2264周缘的内壁。由于第三凸部2264c从腔体2264c周缘向内凸起，所以能够有效地至少限位涡簧222的最外一圈簧体，防止涡簧222意外脱出。
第三实施例。
本实施例与上述第一实施例的区别在于，第一实施例中的齿轮减速箱被替换为带传动箱。具体地，第一实施例中的电机输出齿轮246、第一齿轮224和第二齿轮226被替换为电机输出带轮、第一带轮和第二带轮。
第四实施例。
参考图10～图12，本实施例与上述第一实施例的区别在于，所述涡簧约束件构造为设置在第二槽部2262处的至少一个第四凸部2262c。进一步地，所述第四凸部2262c自所述第二槽部2262靠近所述第二齿轮226旋转中心的侧壁、向朝着第二齿轮226的旋转中心的方向延伸。
具体地，第二槽部2262由齿圈周向壁226a、第一延伸部2262a和第二延伸部2262b围合形成。齿圈周向壁226a构造为环形结构，其构成了第二齿轮226的圆形主体。第二齿轮226的齿分别在齿圈周向壁226a的外周面上，腔体2264则由齿圈周向壁226a的内周面限定。第一延伸部2262a自齿圈周向壁226a的内周面、朝向第二齿轮226旋转中心延伸。第二延伸部2262b自齿圈周向壁226a的内周面、与第一延伸部2262a沿第二齿轮226轴向间隔第一距离的位置，首先朝向第二齿轮226旋转中心延伸形成第二延伸部首段，再大致平行于齿圈周向壁226a地朝向第一延伸部2262a延伸形成第二延伸部尾段。第二延伸部尾段与齿圈周向壁226a之间间隔第三距离，第二延伸部2262b的末端与第一延伸部2262a靠近第二延伸部2262b的面之 间间隔第二距离，第一距离和第三距离限定了第二槽部2262的大小。
第二钩爪2224构造为涡簧222外自由端逆着涡簧222的盘绕方向形成的勾部。当涡簧222与第二齿轮226装配时，将第二钩爪2224卡入第二槽部2262，使第二钩爪2224和涡簧222最外一圈簧体分别位于第二延伸部尾段的两侧，第二钩爪2224与涡簧222最外一圈簧体之间的弯折部位于第一延伸部2262a与第二延伸部2262b的末端之间。
在本实施例中，第四凸部2262c构造为位于第二延伸部2262c的末端、朝向第二齿轮226旋转中心延伸的凸部。优选的，第四凸部2262c沿第二齿轮226半径方向的宽度不小于涡簧222单圈簧体的厚度，且不大于涡簧222单圈簧体厚度的两倍。优选的，在本实施例中，涡簧约束件仅包括一个第四凸部2262c。
第五实施例。
本实施例与上述第四实施例的区别在于，参考图13～图15，所述第四凸部2262c自所述第二槽部2262靠近所述第二齿轮226旋转中心的侧壁、向背离第二齿轮226的旋转中心的方向延伸。具体地，第四凸部2262c构造为位于第二延伸部2262c的末端、朝着背离第二齿轮226旋转中心延伸的凸部。
第六实施例。
本实施例与上述第四实施例的区别在于，参考图16～图18，所述第四凸部2262c自所述第二槽部2262远离所述第二齿轮226旋转中心的侧壁、向朝着第二齿轮226的旋转中心的方向延伸。第四凸部2262c构造为位于第一延伸部2262a与第二延伸部首段之间、自齿圈周向壁226a朝向第二齿轮226旋转中心延伸的凸部。
