具体实施方式
于以下说明中，如有指出请参阅特定附图或是如特定附图所示，其仅是用以强调于后续说明中，所述及的相关内容大部分出现于该特定附图中，但不限制该后续说明中仅可参考所述特定附图。
请一并参阅图1至图4，图1为本发明的马达的示意图，图2为本发明的马达的局部分解示意图，图3及图4为本发明的马达的端盖3及防护组件4的不同视角的分解示意图。本发明的马达M包含一壳体1、一马达电机2、一端盖3及一防护组件4。
壳体1内具有一电机容槽1A，壳体1具有一开口1B，电机容槽1A能通过开口1B与外连通。马达电机2设置于电机容槽1A，马达电机2包含一转子21、一定子22及一转动轴23。转子21与转动轴23相互固定，马达M通电时，转子21及转动轴23能相对于定子22旋转。关于转子21及定子22的具体形式可依据需求变化，图中所示仅为其中一示范方式。
端盖3可以是通过多个螺丝S可拆卸地固定于壳体1的一端，端盖3用以封闭所述开口1B，而使马达电机2被封闭于电机容槽1A中。端盖3彼此相反的两侧面分别定义为一外端面31及一内端面32，端盖3具有一第一轴孔3A，第一轴孔3A贯穿端盖3，端盖3的外端面31向外延伸形成有一环状固定结构33，环状固定结构33环绕第一轴孔3A设置，环状固定结构33的一端内凹形成有一第一容槽3B。第一轴孔3A的内径大于转动轴23的外径，而第一轴孔3A用以提供转动轴23穿设。
防护组件4包含：一固定件41、一内弹性密封件42、一外弹性密封件43、一弹性外盖44及多个锁固件45。端盖3具有多个第一锁孔3C，多个第一锁孔3C位于第一容槽3B中。固定件41对应于多个第一锁孔3C具有多个第二锁孔41A。多个锁固件45与多个第一锁孔3C、多个第二锁孔41A相互锁固，而固定件41是可拆卸地与环状固定结构33相互固定。关于第一锁孔3C及第二锁孔41A的数量不以图中所示为限。固定件41还具有一第二轴孔41B，第二轴孔41B贯穿固定件41，固定件41彼此相反的两端分别内凹形成有一第二容槽41C及外凸形成有一卡合结构411，第二容槽41C与第二轴孔41B相互连通。
内弹性密封件42可拆卸地与卡合结构411相互卡合，且内弹性密封件42卡合于第一容槽3B中，内弹性密封件42具有一第一中心穿孔42A，第一中心穿孔42A贯穿内弹性密封件42设置，第一中心穿孔42A的孔径大于转动轴23的外径，第一中心穿孔42A用以提供转动轴23穿设。在实际应用中，内弹性密封件42外径可以是略大于第一容槽3B的内径，而内弹性密封件42可以是紧配合地卡合设置于第一容槽3B中。
外弹性密封件43可拆卸地设置于第二容槽41C，外弹性密封件43具有一第二中心穿孔43A，第二中心穿孔43A贯穿外弹性密封件43设置，第二容槽41C的内径大于第二中心穿孔43A的孔径，且第二中心穿孔43A的孔径不小于转动轴23的外径，而第二中心穿孔43A用以提供转动轴23穿设。在实际应用中，外弹性密封件43的外径可以是略大于第二容槽41C的内径，而外弹性密封件43与第二容槽41C是紧配合地相互卡合设置。
弹性外盖44具有一第三中心穿孔44A，第三中心穿孔44A贯穿弹性外盖44设置。弹性外盖44还具有一第三容槽44B，弹性外盖44通过第三容槽44B套设于环状固定结构33外，而固定件41、外弹性密封件43及内弹性密封件42对应位于弹性外盖44与环状固定结构33之间(如图7所示)，且多个第一锁孔3C、第二锁孔41A及多个锁固件45被弹性外盖44遮蔽。在实际应用中，第三容槽44B的内径可以是略小于环状固定件41的外径，而第三容槽44B可以是以紧配合的方式套设于环状固定结构33外。在实际应用中，端盖3及固定件41可以是金属材质或高硬度的塑料材质制成，而内弹性密封件42、外弹性密封件43及弹性外盖44则是由能弹性变形的材质所制成，例如：橡胶、硅胶等。
请先参阅图7，其显示为本发明的马达M的局部剖面侧视示意图。如图所示，转动轴23是穿设于第一轴孔3A、第二轴孔41B、第一中心穿孔42A、第二中心穿孔43A及第三中心穿孔44A，且外弹性密封件43、内弹性密封件42及弹性外盖44皆紧密地抵靠于转动轴23的外侧，而外弹性密封件43、内弹性密封件42及弹性外盖44用以防止外部液体沿转动轴23进入至电机容槽1A。
依上所述，本发明的马达M通过防护组件4所包含的固定件41、内弹性密封件42、外弹性密封件43及弹性外盖44等构件的设计，可以大幅地提升马达M防水的能力，特别是可以大幅降低马达M外部的液体通过转动轴23进入电机容槽1A的机率。由于本发明的马达M具有较佳的防水效果，因此，本发明的马达M特别适合应用为水车用马达。
如图3及图4所示，值得一提的是，在较佳的实施例中，前述多个第二锁孔41A是贯穿固定件41设置，且卡合结构411对应于多个第二锁孔41A具有多个第一避让缺口41D，而各个锁固件45与各个第二锁孔41A相互锁固时，各个锁固件45的一部分是通过其中一个第一避让缺口41D。内弹性密封件42对应于多个第一避让缺口41D具有多个第二避让缺口42B，各个锁固件45与各个第一锁孔3C相互锁固时，各个锁固件45的一部分是通过其中一个第二避让缺口42B。通过使卡合结构411具有多个第一避让缺口41D以及使内弹性密封件42具有多个第二避让缺口42B的设计，可以避免多个锁固件45穿设内弹性密封件42，如此，可避免内弹性密封件42被锁固件45破坏。更详细来说，若多个锁固件45会穿过内弹性密封件42，则内弹性密封件42用以提供锁固件45穿过的穿孔(或锁孔)，将可能是导致外部液体进入电机容槽1A中的路径，因此，通过多个第一避让缺口41D及多个第二避让缺口42B等设计，将可相对提升马达M的防水性。
请一并参阅图3至图7，图5为本发明的马达的固定件及内弹性密封件的局部剖面示 意图，图6为本发明的马达的局部分解剖面示意图。如图所示，在较佳的实施例中，固定件41可以是包含一本体412及一环状壁413，固定件41的本体412彼此相反的两端面分别定义为一外端面4121及一内端面4122，外端面4121向内凹陷形成所述第二容槽41C，固定件41的本体412的内端面4122向外延伸形成所述环状壁413及前述卡合结构411，且环状壁413围绕卡合结构411设置。卡合结构411邻近于内端面4122的位置内凹形成一内环状凹槽41E，更具体来说，卡合结构411的一外环侧面4111于邻近本体412的位置向内凹陷形成所述内环状凹槽41E。其中，固定件41的环状壁413相对于内端面4122的高度不小于内环装凹槽的深度。
内弹性密封件42包含一本体421及一环状壁422，前述第一中心穿孔42A是贯穿内弹性密封件42的本体421设置，内弹性密封件42的本体421彼此相反的两端面分别定义为一外端面4211及一内端面4212，内弹性密封件42的本体421的外端面4211向外延伸形成环状壁422，环状壁422与本体421共同形成一卡合容槽42C，卡合容槽42C用以与卡合结构411相互卡合。内弹性密封件42的环状壁422远离本体421的一端向内延伸形成一内环状凸部423，内环状凸部423用以与内环状凹槽41E相互卡合。在实际应用中，内环状凸部423的尺寸可以是略大于内环状凹槽41E的尺寸，而内环状凸部423与内环状凹槽41E是紧配合地相互卡合。
内弹性密封件42的本体421的内端面4212还向外延伸形成一内环状密封部424，内环状密封部424用以设置于第一轴孔3A内，且内环状密封部424所围绕形成的开口的口径小于转动轴23的外径，而转动轴23穿设于第一中心穿孔42A时，内环状密封部424是紧密地抵靠于转动轴23的外侧面231。
如图6所示，当固定件41通过锁固件45固定于环状固定结构33的一侧时，内弹性密封件42将被端盖3及固定件41夹持，且内弹性密封件42的内环状凸部423将对应卡合于内环状凹槽41E中，内弹性密封件42的内环状密封部424则是对应设置于第一轴孔3A中。另外，当固定件41通过多个锁固件45与端盖3的环状固定结构33相互固定时，环状抵靠结构34的一端面341，将抵靠于固定件41的内端面4122，且固定件41的环状壁413、环状抵靠结构34及环状固定结构33将共同形成一外环状凹槽SL。
弹性外盖44包含一本体441及一环状壁442，本体441彼此相反的两端面分别定义为一外端面4411及一内端面4412，弹性外盖44的本体441的外端面4411向外延伸形成一辅助环状壁443，辅助环状壁443环绕第三中心穿孔44A设置，辅助环状壁443远离本 体441的末端向内延伸形成一外环状密封部444。在实际应用中，外环状密封部444所围绕的开口口径，小于转动轴23的外径，而转动轴23穿设于第三中心穿孔44A时，外环状密封部444是紧密地抵靠于转动轴23的外侧面231。
弹性外盖44的本体441的内端面4412向外延伸形成环状壁442，环状壁442相反于本体441的末端向内延伸形成一外环状凸部445。外环状凸部445用以与前述外环状凹槽SL相互卡合，在实际应用中，各个外环状凸部445的尺寸可以是略大于外环状凹槽SL的尺寸，而外环状凸部445可以是以紧配合的方式相互卡合。另外，弹性外盖44的本体441的内端面4412还可以是向外延伸形成两个辅助环状凸部446，两个辅助环状凸部446环绕第三中心穿孔44A设置，且各个辅助环状凸部446相对于内端面4412的高度，小于环状壁442相对于内端面4412的高度。其中，弹性外盖44所包含的辅助环状凸部446的数量可以是依据需求增减，图中所示仅为其中一示范方式。在较佳的实施例中，可以是依据固定件41的厚度、弹性外盖44的环状壁442的高度等几何尺寸，决定各个辅助环状凸部446相对于内端面4412的高度，据以使得弹性外盖44的外环状凸部445卡合于外环状凹槽SL时，多个辅助环状凸部446是紧密地抵靠于固定件41的外端面4121，从而可以有效地防止外部液体进入转动轴23。
值得一提的是，转动轴23邻近于弹性外盖44的部分区段还可以是形成有呈环状的一凸出结构232，凸出结构232的外径大于转动轴23其余区段的外径，而弹性外盖44套设于环状固定结构33时，弹性外盖44的一部分将与凸出结构232紧密地相互抵靠，据以降低外部液体沿着转动轴23进入马达M内部。
依上所述，请参阅图7，本发明的马达M通过弹性外盖44的外环状密封部444、转动轴23的凸出结构232、内弹性密封件42的内环状密封部424及外弹性密封件43等设计，将可以大幅降低马达M外部的液体由转动轴23沿着图7所示X轴方向进入马达M内部的机率；换句话说，马达M外部的液体要由转动轴23沿着图7所示的X轴方向进入马达M内部时，液体将会先后受到外环状密封部444、与凸出结构232相互抵靠的弹性外盖44的部分、内弹性密封件42及外弹性密封件43等至少4层的相关防护结构阻挡。
另外，本发明的马达M通过外环状凸部445、环状抵靠结构34、辅助环状凸部446及内环状凸部423等设计，将可以大幅降低马达M外部的液体由弹性外盖44沿着图7所示Y轴方向进入马达M内部的机率；换句话说，马达M外部的液体要由弹性外盖44沿着图7所示的Y轴方向进入马达M内部时，液体将会先后受到外环状凸部445、环状抵 靠结构34、辅助环状凸部446及内环状凸部423至少4层的相关防护结构阻挡。因此，马达M外部的液体无论是沿着图7所示X轴方向或Y轴方向，欲进入马达M的内部，皆会被多层的相关防护结构阻挡，故本发明的马达M具有相对较佳的防水性。
请一并参阅图3至图6及图8至图13，图8至图13显示为拆卸本发明的马达的固定件、内弹性密封件及外弹性密封件的过程的示意图。如图3及图5所示，固定件41还可以包含多个辅助锁孔41F，各个辅助锁孔41F为具有螺纹的穿透孔，多个辅助锁孔41F分散地形成于固定件41；在实际应用中，各个辅助锁孔41F可以是设置于相邻的两个第二锁孔41A之间。各个辅助锁孔41F用以提供多个辅助锁固件46(例如螺丝)锁固，以让使用者可以通过拉拔与多个辅助锁孔41F相互锁固的辅助锁固件46，而相对轻松地将固定件41、内弹性密封件42及外弹性密封件43一同拔离端盖3。
更具体来说，如图1、图8及图9所示，当使用者欲将固定件41、内弹性密封件42及外弹性密封件43由端盖3上拆卸下来时，用户可以是先将弹性外盖44拔离端盖3，以使固定件41及锁固于其上的多个锁固件45外露。如图10所示，接着，使用者可以利用相关工具(例如螺丝起子)，将多个锁固件45由固定件41上卸除。
特别说明的是，请复参图6及图7，由于内弹性密封件42的一部分是卡合设置于端盖3的第一容槽3B中，且内弹性密封件42的一部分是卡合设置于第一轴孔3A中，因此，在图10所示的状态下，即使多个锁固件45已经由固定件41上卸除，使用者仍难以徒手将固定件41拔离端盖3。另外，若是使用者利用其他工具(例如各式钳子)夹持固定件41，以将固定件41拔离端盖3，此种方式将可能导致固定件41的损坏，且在实际应用中也不易实施。
如图11至图13所示，由于本实施例所举的马达M的固定件41是具有多个辅助锁孔41F，因此，在图10所示的情况下，使用者可以接着将多个辅助锁固件46，锁固于多个辅助锁孔41F，如此，使用者即可通过相关工具(例如各式钳子)夹持多个辅助锁固件46，从而可以相对轻松地将固定件41、内弹性密封件42及外弹性密封件43拔离端盖3。
在实际应用中，各个第二锁孔41A与各个辅助锁孔41F是具有相同的孔径，而防护组件4所包含的多个锁固件45则能与多个辅助锁孔41F相互锁固，也就是说，在图10所示的状态下，使使用者将原本锁固于多个第二锁孔41A的锁固件45卸下后，可以是直接将多个锁固件45，锁固于多个辅助锁孔41F，而后，使用者即可通过相关工具拉拔锁固于多个辅助锁孔41F的锁固件45，据以将固定件41、内弹性密封件42及外弹性密封件43 拔离端盖3。
值得一提的是，由于各个锁固件45是用来将固定件41锁固于端盖3，因此，在较佳的实施例中，各个锁固件45及各个辅助锁固件46可以是尺寸不相同的螺丝，而使用者在图11的状态下，是使用另一些螺丝来锁固于多个辅助锁孔41F中，如此，若是使用者通过工具拉拔多个辅助锁固件46时，多个辅助锁固件46的螺牙受损，仍然不会影响后续使用者将固定件41锁固于端盖3时的密封性，也就是说，若是辅助锁固件46与锁固件45为完全相同的螺丝，在螺丝的螺牙受损时，将会导致螺丝无法再使固定件41锁固于端盖3。
依上所述，通过于固定件41设置多个辅助锁孔41F的设计，将可便于使用者拆卸固定件41、内弹性密封件42及外弹性密封件43，而使用者在拆卸固定件41、内弹性密封件42及外弹性密封件43的过程中，使用者所使用的工具可以是完全不夹持固定件41，而固定件41被拆离端盖3时，固定件41将不会受损，从而可以确保固定件41再次锁固于端盖3时，固定件41与弹性外盖44仍保有相同的密封性。
更具体来说，如前所述，由于弹性外盖44的外环状凸部445是会卡合于由固定件41及端盖3共同形成的外环状凹槽SL中，因此，在固定件41不设置有辅助锁孔41F的实施例中，若使用者利用钳子等工具，夹持固定件41的外缘，以将固定件41、内弹性密封件42及外弹性密封件43拔离端盖3，且在操作过程中，钳子等工具使得固定件41的外缘受损，如此，将可能使得弹性外盖44的外环状凸部445无法紧密地卡合于由固定件41与端盖3共同形成的外环状凹槽SL中，进而可能降低马达M的防水性。因此，上述使固定件41额外设置多个辅助锁孔41F并配合多个辅助锁固件46等设计，将可以降低固定件41在被拔离端盖3的过程中受损的机率，且可据以确保固定件41再次锁固于端盖3，而弹性外盖44套设于环状固定结构33后的防水性。
综上所述，本发明的马达M通过端盖3及防护组件4等构件的设计，可以大幅提升马达M整体的防水性，特别是可以大幅降低马达M外部的水气通过转动轴23进入马达M内部的机率；另外，本发明的马达M通过于固定件41额外设置多个辅助锁孔41F等设计，可以让使用者相对轻松地将固定件41拔离端盖3。
以上所述仅为本发明的较佳可行实施例，非因此局限本发明的专利范围，故凡运用本发明说明书及附图内容所做的等效技术变化，均包含于本发明的保护范围内。
