相关申请的交叉参考
本申请要求于2004年2月6日提交的美国临时专利申请No.60/542,343的优先权。
技术领域
本发明一般地涉及一种驱动机构,更具体地,涉及一种空心轴电动机组件。
背景技术
用于座椅移动和人机工程支承移动的电动机驱动装置是已知的。通常,电动机具有轴,并且在该轴上安装有齿轮传动组件。在已知的设备中,只能从电动机的一端获得来自电动机/齿轮传动装置的输出。一些时候,需要双输出电动机和行星齿轮传动装置。这种设备可以提供紧凑且成本低的成套组件,以驱动任何数量的座椅机构。在本领域,仍然需要紧凑且成本低的具有双输出的电动机和齿轮传动装置组合。
座椅导轨组件是已知的。一些座椅导轨组件可以包括驱动机构和锁止机构。这些设备有些复杂。例如,可能需要连接到驱动机构的第一致动器和连接到锁止结构的第二致动器。第一致动器和第二致动器必须协调工作,以便锁止机构在驱动机构接合之前“解锁”。这经常包括复杂的、低效的且昂贵的止动件和限位开关装置。虽然独立的锁止机构有利于座椅导轨组件的抗撞性能,但复杂的止动件和限位开关装置却大大增加了座椅导轨组件的成本。此外,具有两个独立的致动器大大增加了座椅导轨组件的重量。
因此,在本领域,仍然需要具有设置成操作独立的驱动机构和锁止机构的单个致动器的座椅导轨组件。也仍然持续需要重量轻、尺寸紧凑、成本低且抗撞的座椅导轨组件。
另外,在授权给Ikegaya等人的美国专利No.4,986,514中公开了一种电动机和行星齿轮装置组合。Ikegaya使用行星齿轮传动装置来调整座椅靠背的倾斜度。该‘514专利公开了将电动机组件靠近座椅靠背放置,并将行星齿轮装置连接到座椅靠背。这导致庞大的成套组件。
因此,仍然需要紧凑且成本低的倾斜机构。

在第一示例中,所述空心轴电动机组件用于驱动导轨驱动机构。在该第一示例中,具有座椅导轨组件。该座椅导轨组件包括座椅导轨、导轨驱动机构和锁止机构。当致动所述导轨驱动机构时,所述空心轴电动机组件操作一杆,以在调整所述座椅导轨位置之前松开所述锁止机构。在调整了座椅导轨位置后,所述导轨驱动机构脱离接合,此后,所述空心轴电动机组件操作所述杆,以再次接合所述锁止机构。
在第二示例中,所述空心轴电动机组件形成座椅铰链的一部分。换句话说,所述空心轴电动机组件与所述座椅铰链同轴。这样,可以接合所述空心轴电动机组件,以调整所述座椅靠背的倾斜度。这提供了用于电动地调整所述座椅靠背的倾斜度的紧凑装置。

具体实施方式
参考附图,其中相同的标号指示相同的元件,图1和图2示出空心轴电动机组件10。该空心轴电动机组件10包括电动机11。该电动机11包括空心轴12。如图3最好地示出的,该空心轴12连接到所述电动机11的电枢13。该空心轴12包括外径14和内径16。再回到图1,第一齿轮20连接到空心轴12。在所述实施例中,该第一齿轮20连接到所述空心轴12的端部18,该第一齿轮20是行星齿轮系的太阳轮。虽然在所述实施例中示出的是行星齿轮系,但使用其它类型的齿轮系与所述空心轴12接合也在本发明的范围内。
所述第一齿轮20与行星齿轮传动组件30驱动联接。在所述实施例中,该行星齿轮传动组件30是总传动比为500∶1的三级行星齿轮传动组件。然而,本领域的技术人员应理解,可以使用具有更大或更小传动比的任意级数的齿轮传动组件。行星齿轮传动组件罩22罩住所述行星齿轮传动组件30,并连接到所述电动机11。该行星齿轮传动组件罩22也被称作壳体。所述行星齿轮传动组件30与传动轴架40驱动联接。
在图1所示的实施例中,第一行星齿轮31围绕第一齿轮20公转并由所述第一齿轮转动。第一传动盘32具有第一传动盘轴33。所述第一行星齿轮31转动该第一传动盘轴33,由此转动所述第一传动盘32。第二齿轮34连接到该第一传动盘32,因此与该第一传动盘32一起转动。第二行星齿轮35围绕第二齿轮34公转并由所述第二齿轮转动。第二传动盘36具有第二传动盘轴37。所述第二行星齿轮35转动该第二传动盘轴37,由此转动所述第二传动盘36。第三齿轮38连接到该第二传动盘36,因此与该第二传动盘36一起转动。第三行星齿轮39围绕第三齿轮38公转并由所述第三齿轮转动。所述传动轴架40具有第三传动轴42。所述第三行星齿轮39转动该第三传动轴42,由此转动所述传动轴架40。
如图2最好地示出的,一些实施例可以包括任何数量的减少摩擦的部件23,以减少转动部件的摩擦。例如,该减少摩擦的部件23可以是轴承。
下面参考图4,所述传动轴架40连接到至少一个从动件50。该从动件50可以是任何数量的传统部件。例如,该从动件可以是拉线和滑轮装置、凸轮或轴。在图4所示的实施例中,在传动轴架40和从动件50之间具有中间件52,即传动轴。
参考图5可见,所述中间件52在内径16中。该中间件52可以具有与所述内径16相同的尺寸或比该内径小。例如,该中间件52可以比该内径16小,以便润滑。
图6示出关于如何使用该空心轴电动机组件10的第一示例。在图6中,具有座椅导轨组件100。该座椅导轨组件100包括导轨驱动机构110。该导轨驱动机构110包括第一导轨112和第二导轨114。第二导轨114从第一导轨112偏置。每个导轨112和114都包括齿条部116。当第一锁止机构120在“锁定”位置时,该第一锁止机构120与所述第一导轨112形锁合(positively engage)。当第二锁止机构122在“锁定”位置时,该第二锁止机构122与所述第二导轨114形锁合。
第一挤压滑动件124可滑动地连接到所述第一导轨112。第二挤压滑动件126可滑动地连接到所述第二导轨114。座椅(图11中最好地示出的)安装在所述第一和第二挤压滑动件124和126上。当所述锁止机构120和122都被松开时,该座椅仅能在所述挤压滑动件124和126上向前或向后移动。在碰撞时,所述锁止机构120和122有助于将所述挤压滑动件并从而将所述座椅保持在所述导轨112和114上。
所述第一锁止机构120和所述第二锁止机构122都包括至少一个可枢转锁止件。在图8、图9和图10所示的实施例中,所述锁止机构120和122都包括第一可枢转锁止件130和第二可枢转锁止件132。该可枢转锁止件130和132被弹性偏置,以与所述齿条部116接合。所述第一可枢转锁止件130包括第一臂134。所述第二可枢转锁止件132包括第二臂136。
解锁轴140连接所述第一锁止机构120和第二锁止机构122。该解锁轴140转动,以将所述锁止机构120和122从“锁定”位置移动到“解锁”位置,或者相反。闩杆142连接到所述解锁轴140。例如,该闩杆142可焊接或紧固在该解锁轴140上。
所述闩杆142与凸轮150接合。该凸轮150连接到所述空心轴电动机组件10。在所述实施例中,该凸轮150连接到所述壳体22,或者,如本领域技术人员可以理解的,该凸轮150可以与所述壳体22成一体。在该壳体22和所述解锁轴140之间使用其它联接组件也在本发明的范围内。
如图7最好地示出的,导轨驱动轴160连接到所述空心轴电动机组件10。该导轨驱动轴160包括上部162和下部164。第一导轨驱动齿轮170连接到上部162。第二导轨驱动齿轮172连接到下部164。在所述实施例中,导轨驱动齿轮170和172是直齿轮。然而,本领域的技术人员应理解,可以使用其它类型的齿轮。所述第一导轨驱动齿轮170与所述第一导轨112接合。所述第二导轨齿轮172与所述第二导轨114接合。虽然图6中示出的是空心轴电动机组件10,但本领域的技术人员应理解,也可使用具有双输出的传统电动机组件。
在操作中,致动所述空心轴电动机组件10。例如,可以通过接合开关(未示出)来致动该空心轴电动机组件10。一旦该空心轴电动机组件10被致动,电动机的转矩就沿第一方向转动所述壳体22和所述凸轮150。该凸轮150与闩杆142接合,以便该闩杆142转动所述解锁轴140,由此松开所述第一和第二锁止机构120和122。换句话说,在沿所述第一和第二导轨112和114移动所述座椅之前,所述空心轴电动机组件自动将所述锁止机构置于“解锁”位置。一旦锁止机构120和122被松开,锁止机构120和122就通过作为止动件阻止所述解锁轴140继续转动。继而,该解锁轴140反作用于所述闩杆142。因此,该闩杆142阻止所述壳体22和凸轮150继续转动。例如,在所述锁止机构120和122被松开之前,所述壳体可以转动5至20度。此后,所述电动机11作用在导轨驱动轴160上。该导轨驱动轴160转动,由此调整所述第一和第二挤压滑动件124和126的位置,以调整所述座椅的位置。
当所述第一和第二挤压滑动件124和126被调整到所希望位置时,所述空心轴电动机组件脱离接合。此后,由所述闩杆142及锁止机构120和122构成的组件提供的弹力使该闩杆142作用在所述凸轮150上,以便所述壳体22和该凸轮150沿与所述第一方向相反的方向转动。在该凸轮150和壳体22略微转动后,所述闩杆142转动所述解锁轴140,以便与所述锁止机构120和122接合。换句话说,在所述挤压滑动件124和126被调整后,锁止机构120和122被自动置于“锁定”位置。
图8示出用于沿第一方向移动所述座椅的向前凸轮位置。在图8所示的示例中,希望沿箭头A的方向相对于所述第一导轨112和第二导轨114移动所述座椅。在该示例中,凸轮150沿箭头B的方向转动,并与闩杆142接合。该闩杆142转动所述解锁轴140,从而在所述第一可枢转锁止件130上产生转矩。因此,该第一可枢转锁止件130围绕第一轴137转动。该第一可枢转锁止件130的枢转运动使第一臂134与第二臂136接合。该第二臂136的运动使所述第二可枢转锁止件132围绕第二轴138转动。所述第一和第二可枢转锁止件130和132一直枢转,直到不再与所述齿条部116接合。这松开了所述第一锁止机构120和所述第二锁止机构122,并且允许所述第一和第二挤压滑动件124和126相对于所述第一和第二导轨112和114移动。
图9示出当所述座椅静止不动时的中间凸轮位置。在图9所示的示例中,所述第一和第二锁止机构120和122处于“锁定”位置。在该位置,所述第一和第二可枢转锁止件130和132与所述齿条部116接合,并且所述凸轮150与所述闩杆142接触或几乎接触。
图10示出用于沿与所述第一方向相反的方向移动所述座椅的倒转凸轮位置(reverse cam position)。在图10所示的示例中,希望沿箭头C的方向相对于所述第一导轨112和第二导轨114调整所述挤压滑动件124和126。在该示例中,所述凸轮150沿箭头D的方向转动,并与所述闩杆142接合。该闩杆142转动所述解锁轴140,从而在所述第一可枢转锁止件130上产生转矩。然后,该第一可枢转锁止件130围绕第一轴137转动。该第一可枢转锁止件130的枢转运动使第一臂134与第二臂136接合。该第二臂136的运动使所述第二可枢转锁止件132围绕第二轴138转动。所述第一和第二可枢转锁止件130和132一直枢转,直到不再与所述齿条部116接合。这松开了所述第一锁止机构120和所述第二锁止机构122,并且允许所述第一和第二挤压滑动件124和126相对于所述第一和第二导轨112和114移动。
在第二示例中,所述空心轴电动机组件10包含在座椅铰链中。图11示出具有座椅底部210和座椅靠背212的座椅200。所述座椅底部210和座椅靠背212都包括框架(未示出)。该座椅靠背212铰链连接到该座椅底部210。在图12所示的实施例中,所述空心轴电动机组件10包含在所述座椅铰链中。
图12示出所述铰链装置。所述空心轴电动机组件10连接到轴220。该轴220刚性地连接到座椅底部的框架。所述空心轴电动机组件的壳体22刚性地连接到座椅靠背212。例如,该壳体22可以连接到该座椅靠背212的框架。或者,所述轴可以连接到所述座椅靠背的框架,所述壳体可以连接到所述座椅底部的框架,只要所述空心轴电动机组件10的转动能使所述靠背和底部彼此相对移动。
在操作中,接合所述空心轴电动机组件10。此后,所述空心轴电动机10转动所述壳体22。继而,该壳体22将座椅靠背212移动到所希望的倾斜度。
鉴于以上所述,可以看到,实现并获得了本发明的多个优点。
为了最好地解释本发明的原理及其实际应用,选择并描述了所述实施例,从而使本领域的技术人员在各种实施例中和在适于所预期的特殊用途的各种变型中最好地应用本发明。
由于可以在不脱离本发明的范围的情况下对本文所述和所示的结构和方法进行各种修改,因此上述说明中所包含的或附图中所示出的所有内容应被解释为示例性的,而非限制性的。例如,虽然示出的是三级行星齿轮减速装置,但本领域的技术人员应理解,可以使用更多或更少的级数。因此,本发明的宽度和范围不应该受到上述示例性实施例的限制,而应该仅由所附的权利要求及其等同物限定。
