请参阅图2,在一些实施方式中,基体10可包括固定板11、机壳12和盖板13,机壳12安装在固定板11上,输出组件20也安装在固定板11上,连杆组件30安装在机壳12与固定板11上,盖板13可盖设在机壳12上并罩设输出组件20和连杆组件30。驱动电机411可安装在固定板11上,驱动滑块42与固定板11和机壳12滑动连接。如此,将开关门装置100的所有零部件都安装在基体10内,基体10可以将开关门装置100作为一个完整的模块安装在电器设备1000的机体200或者门体300上,而无需在机体200和门体300上增设其它的结构,便于拆卸,能够兼容不同的机型,通用性高。另外,基体100作为整个开关门装置100的承载主体和安装主体,为了保证支撑和安装的稳定性,基体10的固定板11、机壳12以及盖板13均可采用强度较高的金属材料制成,在一个可能的实施方式中,基体10可采用轻质铝合金材料支撑。当然,在一些实施方式中,基体10也可以采用强度较高的非金属材料制成,具体在此不作限制,只需要满足安装要求即可。当然,可以理解的是,在一些实施方式中,基体10也可以仅仅只是包括固定板11而不具有机壳12和盖板13,或者只包括固定板11和机壳12,具体设置可根据实际情况进行选择,在此不作具体限制。
在本申请中,开关门装置100可作为一个单独的模块安装在机体200或者门体300的顶部靠近门体300的转轴所在的位置。在一些实施方式中,开关门装置100的基体10可固定安装在门体300的顶部角落位置,在这样的情况下,输出轴21可与机体200上的转轴部同轴固定设置,这样,在输出轴21转动时,由于输出轴21与机体200固定连接,输出轴21传递出的扭矩会带动整个门体300相对机体200以实现自动开关门动作,在这样的情况下,在开关门装置100驱动门体300转动的同时,开关门装置100也整体跟随门体300相对机体200转动。当然,可以理解的是,在一些实施方式中, 也可以在门体300上设置用来传动的齿轮,在机体200的转轴部位上也可设置与门体300上的齿轮啮合的齿轮,这样,在输出轴21转动时,输出轴21会带动门体300上的齿轮转动,从而带动整个门体300和开关门装置100相对机体200转动。
另外,可以理解的是,在其它实施方式中,也可以是将开关门装置100的基体10固定安装在机体200顶部的角落位置,输出轴21则与门体300上的转轴部同轴固定设置,这样,在输出轴21转动时,由于输出轴21与门体300的转轴固定连接,输出轴21转动时会带动门体300转动以实现自动开关门动作。在这样的情况下,在门体300转动时,开关门装置100不会跟随门体300转动。当然,在一些实施方式中,也可以在机体200上设置用来传动的齿轮,在门体300的转轴上也可设置与机体200的齿轮啮合的齿轮,这样,在输出轴21转动时,输出轴21会带动机体300上的齿轮转动,从而通过齿轮带动门体300转动。
在本申请的实施方式中,对于开关门装置100的具体安装位置不作限定,只需要能够通过开关门装置100带动门体300转动即可。
请参阅图4至图8,在某些实施方式中,输出组件20还包括输出轮23和驱动轮22,驱动轮22可转动地安装在基体10上,输出轮23也可转动地安装在基体10上。
其中,连杆组件30和驱动轮22铰接,驱动轮22与连杆组件30的铰接点与驱动轮22的转动中心偏心设置。输出轮23与驱动轮22动力连接,输出轴21与输出轮23固定连接,驱动组件40用于驱动连杆组件30转动以带动驱动轮22转动从而带动输出轮23和输出轴21转动。
如此,在连杆组件30转动时,连杆组件30会带动驱动轮22转动,驱动轮22会带动输出轮23转动输出轴21跟随输出轮23同步转动,输出轮23则通过输出轴21带动门体300在机体200上转动以实现开关门动作。
具体地,在本申请的实施方式中,“输出轮23与驱动轮22动力连接”可以理解为两者直接接触以实现动力传递或者是两者通过中间的连接元件实现间接接触以实现动力的传递,在一个可能的实施方式中,输出轮23和驱动轮22可均为齿轮,两者直接啮合在一起或者是通过中间传动齿轮来实现间接啮合,在另外的实施方式中,输出轮23和驱动轮22也可为带轮,两者之间通过传动带实现传动。此外,在一些实施方式中,输出轮23和驱动轮22也可均为链轮,两者之间通过传动链来实现动力的传动。在本申请中并不对输出轮23和驱动轮22之间的传动方式进行限制,只需要两者之间能够进行动力传递即可。
在这样的实施方式中,输出组件20还可包括第一轴承24和第二轴承25,驱动轮22的中心转轴部分可与第一轴承24连接从而将驱动轮22可转动地支撑在基体10上以保证驱动轮22转动的稳定性,输出轮23的中心转轴部分可与第二轴承25连接从而将输出轮23可转动地支撑在基体10上以保证驱动轮22转动的稳定性,输出轴21则可与输出轮23的中心转轴部分同轴固定连接在一起,也即是说,输出轴21是跟随输出轴21同轴转动,“同轴”可以理解为两者的轴线完全重合或者是两者的轴线之间的间隔距离处于装配误差的允许范围内,在下文若出现相同或者类似的说明书,也可参照此处理解。在本申请中,对于第一轴承24和第二轴承25的类型不作具体限制,其可为滚珠轴承、圆锥滚子轴承,也可以是圆柱滚子轴承等等,只需要能够满足支撑要求即可。
可以理解的是,在本申请的实施方式中,连杆组件30与驱动轮22两者之间的铰接点与驱动轮22在转动时的转动轴线的中心偏心可以保证连杆组件30在转动时能够带动驱动轮22转动。
较佳地,在本申请中,连杆组件30与驱动轮22的铰接点可位于驱动轮22的外围边缘位置。铰接点与驱动轮22的中心之间的距离越远越好。这样,连杆组件30可通过较小的转动形成来带动驱动轮22实现较大的转动行程,也即是说,通过连杆组件30和驱动轮22的配合设置可以做到在较小的体积内形成较大的门体300开合行程。
请参阅图4-图8,在某些实施方式中,驱动轮22和输出轮23均为齿轮,驱动轮22和输出轮23的动力连接。
如此,可通过齿轮传动的方式来实现驱动轮22和输出轮23之间的动力传递,齿轮传动的稳定性较高,可以提供较高的扭矩,从而保证门体300开合的稳定性。
具体地,在图4-图8所示的实施方式中,驱动轮22和输出轮23均为外齿轮,两者直接啮合在一 起。可以理解的是,为了使得驱动轮22在转动较小的形成能够使得门体300具有更大的转动行程,在本申请中,驱动轮22的分度圆直径要大于输出轮23的分度圆直径,驱动轮22的齿数要大于输出轮23的齿数,也就是说,驱动轮22的径向径向要大于输出轮23的径向尺寸。这样,在驱动轮22转动较小的角度时,输出轮23在驱动轮22的带动下能够转动更大的角度,从而实现大行程的门体300开合,可以做到在较小的体积内形成较大的门体300开合行程,示例性地,在一个例子中,在驱动轮22转动10°时,输出轮23在驱动轮22的带动下则可转动30°甚至更大,从而使得门体300也能够转动相应的角度。
当然,可以理解的是,在一些实施方式中,驱动轮22和输出轮23也可以不是直接啮合在一起,而是在基体10上还设置有可以转动的传动齿轮,传动齿轮的数量可以为一个也可以为多个,驱动轮22和输出轮23之间可以通过一个或者多个传动齿轮依次啮合在一起以实现动力的传递,具体在此不作限制。
当然,可以理解的是,在一些实施方式中,驱动轮22和输出轮23也可均为带轮,输出组件20还包括传动带,传动带绕设在驱动轮22和输出轮23上。如此,通过带传动的方式也同样能够实现动力的传递。
具体地,在这样的实施方式方式中,传动带可以为平带也可以为V带以实现平带传动护着V带传动。同理,为了保证能够驱动轮22能够以较小的角度来带动输出轮23转动较大的角度以实现门体300的大行程开合,在这样的实施方式中,驱动轮22的直径要大于输出轮23的直径。
请参阅图4和图5,在某些实施方式中,连杆组件30包括开门连杆组31和关门连杆组32,开门连杆组31与输出组件20铰接,关门连杆组32与开门连杆组31铰接,驱动组件40能够可选择性地驱动开门连杆组31件30和关门连杆组32转动。在驱动组件40驱动开门连杆组31转动时,开门连杆组31带动输出轴21沿第一方向转动;在驱动组件40驱动关门连杆组32转动时,关门连杆组32带动开门连杆组31反向转动从而带动输出轴21沿第二方向转动,第二方向与第一方向相反。
如此,在开门时,只需要通过驱动组件40来对开门连杆组31进行开门连杆组41进行驱动即可实现门体300的开启,而关门时,则只需要通过驱动组件40来对关门连杆组32进行驱动,进而带动开门连杆组31反方向转动即可实现关门动作,在开门和关门动作均由开门连杆组31执行,而无需设置额外的关门驱动结构。
具体地,在这样的实施方式中,在门体300与机体200的铰接处位于门体300和机体200的右侧时,在机体200的顶部向下的视角中,第一方向为逆时针方向,第二方向为顺时针方向。
在这样的实施方式中,开门连杆组31可与输出组件20的驱动轮22铰接,这样,在驱动组件40直接驱动开门连杆组31动作时,开门连杆组31会带动驱动轮22转动,驱动轮22通过输出轮23转动以实现门体300的开启。
在驱动组件40与开门连杆组31分离且驱动关门连杆组32动作时,由于关门连杆组32与开门连杆组31铰接,关门连杆组32在动作时会带动开门连杆组31反向转动从而带动驱动轮22反向转动,驱动轮22则通过输出轮23带动输出轴21反向转动以实现门体300的关闭。
进一步地,请参阅图4-图8,在某些实施方式中,开门连杆组31包括第一连杆311和第二连杆312,第一连杆311的中间部位与基体10铰接,第一连杆311的一端与第二连杆312铰接,另一端能够在驱动组件40的驱动下带动第一连杆311转动。第二连杆312的一端与第一连杆311的一端铰接,另一端与输出组件20铰接,驱动组件40能够驱动第一连杆311转动并通过第二连杆312带动输出组件20转动,从而带动输出轴21沿第一方向转动。
关门连杆组32与第一连杆311铰接,关门连杆组32与第一连杆311的铰接点位于第一连杆311与基体10的铰接点和第一连杆311与第二连杆312铰接点之间;驱动组件还能够驱动关门连杆组32转动以带动第一连杆311反向转动,从而通过第二连杆312带动输出组件20反向转动以带动输出轴21沿第二方向转动。
如此,通过设置两个相互铰接的第二连杆312以及第一连杆311即可实现门体300的开启,在关门时,只需要通过关门连杆组32来带动第一连杆311沿相反的方向转动即可实现门体300的关闭,结构较为简单。
具体地,在这样的实施方式中,第二连杆312远离第一连杆311的一端与驱动轮22铰接,在开门时,第一连杆311远离第二连杆312的一端在驱动组件40的驱动下动作,从而使得第一连杆311在基体10上转动,第一连杆311在转动时带动第二连杆312运动,第二连杆312带动驱动轮22在基体10上转动,驱动轮22带动输出轮23和输出轴21沿第一方向转动,在关门时,只需要驱动组件40驱动关门连杆组32转动即可带动第一连杆311相对开门时沿反方向转动,第二连杆311则通过第二连杆312带动驱动轮22反向转动,驱动轮22则带动输出轮23和输出轴21沿与第一方向的反向方向(即第二方向)转动,这样,只需要通过在不同的情况下驱动第一连杆311实现正转和反转即可实现自动开关门动作。
可以理解的是,在一些实施方式中,开门连杆组31也不仅限于包括第二连杆312以及第一连杆311。
具体地,在一些情况下,在第二连杆312与第一连杆311之间还可连接设置有其它的连杆。在一个可能的实施方式中,可在第一连杆311和第二连杆312之间还连接设置一根连杆,该连杆的两端分别第二连杆312与第一连杆311铰接,在第一连杆311动作时,该连杆在第一连杆311的带动下动作,从而带动第二连杆312动作以执行开门动作。可以理解的是,在本申请中,只需要能够带动输出组件20的驱动轮22转动即可,具体对连杆的数量不作限制,当然,为了节约制造成本,关门连杆组32的连杆的数量越少越好。
请参阅图4-图8,在某些实施方式中,关门连杆组32包括第三连杆321和第四连杆322,第三连杆321的一端与第一连杆311铰接,另一端与的第四连杆322铰接,第四连杆322的中间部位与基体10铰接,第四连杆322一端与第三连杆321铰接,另一端能够在驱动组件40的驱动下带动第四连杆322转动,从而通过第三连杆321带动第一连杆311转动以通过第二连杆312带动输出组件20反向转动,从而带动输出轴21沿第二方向转动。
如此,只需要通过设置两个铰接在一起的第四连杆322和第三连杆321且第三连杆321与第一连杆311铰接即可使得第四连杆322能够在驱动组件40的带动下动作,从而带动第三连杆321动作,第三连杆321则驱动第一连杆311转动以实现输出轴21的反向转动从而实现关门动作。
可以理解的是,这样的实施方式中,在开门时,是驱动组件40直接作用或者是通过其它元件作用与第一连杆311以使得第一连杆311转动从而实现开门动作,在关门时,是驱动组件40作用与第四连杆322,第四连杆322在转动时带动第三连杆321动作,第三连杆321则带动第一连杆311反方向转动以实现关门动作。
当然,可以理解的是,在一些实施方式中,关门连杆组32也不仅限于包括第四连杆322和第三连杆321,也即是说,在一些实施方式中,在第四连杆322与第三连杆321之间还可连接设置有其它的连杆,示例性地,在一个可能的实施方式中,可在第四连杆322和第三连杆321之间还连接设置一根连杆,该连杆的两端可分别与第四连杆322以及第三连杆321铰接,在第四连杆322转动时,第四连杆322可通过该连杆来带动第三连杆321动作以执行关门动作。可以理解的是,在本申请中,只需要在第四连杆322被驱动组件40驱动时能够带动第一连杆311反方向转动即可,具体对关门连杆组32的连杆的数量不作限制,当然,为了节约制造成本,关门连杆组32的连杆的数量越少越好。
请参阅图4和图5,在某些实施方式中,第四连杆322远离第三连杆321的一端形成凸轮部3221,凸轮部3221用于与驱动组件40接触,驱动组件40能够通过凸轮部3221带动第四连杆322转动。
如此,通过凸轮部3221来与驱动组件40接触可以更好地实现对第四连杆322的驱动。
具体地,在这样的实施方式中,驱动组件40可包括驱动凸轮412,驱动凸轮412可以在转动过程中驱动第一连杆311和第四连杆322的凸轮部3221,在驱动凸轮412驱动第一连杆311转动时实现门体300的打开,在驱动凸轮412驱动凸轮部3221转动时,第四连杆322带动第三连杆321动作,第三连杆321则带动第一连杆311反转以实现门体300的关闭。
请参阅图4-图8,在某些实施方式中,驱动组件40包括驱动部41和驱动滑块42,驱动部41与基体10可转动地连接,驱动滑块42与基体10滑动连接且与开门连杆组31接触,驱动部41能够选择性地与驱动滑块42或者关门连杆组32抵持。
在驱动部41与驱动滑块42抵持时,驱动部41能够驱动驱动滑块42相对基体10朝远离驱动组 件40的方向滑动,从而带动开门连杆组31转动以带动输出组件20的输出轴21沿第一方向转动;
在驱动部41与关门连杆组32抵持时,驱动部41能够驱动关门连杆组32转动以带动开门连杆组31件30反向转动从而带动输出轴21沿第二方向转动。
如此,驱动滑块42与开门栏杆组接触,驱动部41能够驱动滑块42滑动以带动开门连杆组31转动从而使得输出轴21沿第一方向转动以实现开门动作。
具体地,在这样的实施方式中,基体10上可开设有滑槽121,滑槽121沿远离驱动组件40的方向延伸,驱动滑块42与滑槽121滑动连接且能够沿滑槽121滑动,开门连杆组31的第一连杆311与驱动滑块42接触。在驱动部41驱动驱动滑块42滑动时,驱动滑块42会带动第一连杆311的一端转动从而带动整个第一连杆311转动,第一连杆311转动时带动第二连杆312动作以带动驱动轮22转动,驱动轮22则通过输出轮23带动输出轴21沿第一方向转动以实现开门动作。
在驱动部41与驱动滑块42分离且与关门连杆组32抵持时,驱动部41与关门连杆组32的第四连杆322抵持,驱动部41驱动第四连杆322转动,第四连杆32则带动第三连杆321动作,第三连杆321则带动第一连杆311反向转动,第一连杆311反向转动使得输出轴21沿与第一方向相反的方向(也即第二方向)转动转动以实现关门动作。
请参阅图6至图8,在某些实施方式中,开关门装置100还包括弹性机构50,弹性机构50安装在基体10上且抵持驱动滑块42,弹性机构50用于给驱动滑块42施加弹性力以使驱动滑块42保持朝驱动组件40一侧运动的趋势,驱动组件40能够抵持且驱动驱动滑块42克服弹性力朝远离驱动组件40的方向滑动。
如此,在开门时,可通过驱动部41来使得驱动滑块42克服弹性机构50的弹性力以实现第一连杆311的转动,在关门时,驱动部41与驱动滑块42分离后与关门连杆组32的第四连杆322抵持,驱动滑块42在弹性机构50的作用下逐渐复位且与第一连杆311的一端分离,第四连杆322在驱动部41的带动下转动以带动第一连杆311反向转动。
具体地,在这样的实施方式中,弹性机构50可为包括但不限于弹簧等具有弹性元件,只需要弹性机构50能够给驱动滑块42施加弹性力即可,以弹性机构50位弹簧为例,弹簧可安装在基体10的机壳12上,弹簧的两端分别抵持机壳的内壁以及驱动滑块42。可以理解,在这样的实施方式中,在门体300处于关门状态时,第一连杆311的一端与驱动滑块42接触,在驱动部41驱动驱动滑块42运动的过程中,驱动滑块42带动第一连杆311动作从而实现开门动作。
在需要关门时,驱动部41与驱动滑块42分离后与第四连杆322抵持,此时,驱动滑块42在弹性机构50的作用下朝驱动组件40所在一侧滑动且与第一连杆311的一端分离,第四连杆322在驱动部41的带动下转动且通过第三连杆321带动第一连杆311反向转动以实现关门动作,在这个过程中,第一连杆311靠近驱动滑块42的一端向驱动滑块42运动且最终抵持在驱动滑块42上,以便进行下一次开门动作。
当然,可以理解的是,在一些实施方式中,与可不设置上述的驱动滑块42,而是在第一连杆311的一端形成有抵持部,该抵持部用于与驱动部41相抵持以使驱动部41能够驱动第一连杆311转动,在这样的情况下,在基体10上可形成有弧形的引导滑槽121,第一连杆311可与该引导滑槽121配合,在驱动部41驱动第一连杆311转动时,第一连杆311的转动轨迹与引导滑槽121相对应,具体在此不做限制。
请参阅图4和图5,在某些实施方式中,开关门装置100还可包括第一微动开关60,第一微动开关60设置在基体10上,第一微动开关60与驱动组件40电性连接且能够被驱动滑块42触发,在驱动滑块42触发第一微动开关60时,第一微动开关60控制驱动组件40停止工作。
如此,在门体300打开的过程中,在驱动滑块42触发第一微动开关60后,表示门体300已经打开到了最大位置,此时,第一微动开关60断开驱动组件40的电源,使得驱动组件40停止工作,以避免在门体300打开至最大角度后驱动组件40还在输出转动扭矩而造成堵转卡死。
当然,可以理解的是,在上述无需设置驱动滑块42的技术方案中,也可以是将第一微动开关60设置在第一连杆311的转动路径上,在第一连杆311转动移动角度后,第一连杆311可直接触发第一微动开关60。
请参阅图4和图5,开关门装置100还可包括第二微动开关70,第二微动开关70设置在基体10上,第二微动开关70与驱动组件40电性连接且能够被关门连杆组32触发,在关门连杆组32触发第二微动开关70时,第二微动开关70控制驱动组件40停止工作。
如此,在门体300关闭的过程中,在关门连杆组32触发第一微动开关60后,表示门体300已经关闭,此时,第二微动开关70断开驱动组件40的电源,使得驱动组件40停止工作,以避免在门体300完全关闭后驱动组件40还在输出转动扭矩而造成堵转卡死。
具体地,在这样的实施方式中,第二微动开关70可位于第四连杆322的凸轮部3221转动路径上,在驱动组件40驱动凸轮部3221转动以实现关门的过程中,在凸轮部3221触发第二微动开关70后,表示此时门体300已经关闭到位,可以控制驱动组件40停止动作。
请参阅图4-图8,在某些实施方式中,驱动组件40可包括驱动电机411和驱动凸轮412,驱动电机411固定安装在基体10上,驱动凸轮412固定安装在驱动电机411的电机轴上,电机用于驱动驱动凸轮412转动且通过驱动凸轮412带动连杆组件30相对基体10转动以带动输出轴21转动,从而带动门体300相对机体200转动。
如此,通过驱动凸轮412和连杆组件30来对输出轴21进行驱动以实现开关门动作,可以做到在较小的体积内形成较大的开合形成。
具体地,在这样的实施方式中,在驱动组件40具有上述驱动滑块42的情况下,上述驱动部41即包括驱动凸轮412和以及驱动电机411,在关门状态下需要打开门体300时,驱动电机411驱动驱动凸轮412转动,驱动凸轮412驱动驱动滑块42滑动,驱动滑块42在滑动的同时带动第一连杆311转动,第一连杆311则带动第二连杆312动作,第二连杆312带动驱动轮22转动,驱动轮22带动输出轮23和输出轴21沿第一方向转动以实现开门动作。
此时,在需要关门时,驱动凸轮412可在驱动电机411的带动下与驱动滑块42逐渐分离,并且与第四连杆322的凸轮部3221逐渐接触,从而通过凸轮部3221带动第四连杆322转动,第四连杆322通过第三连杆321带动第一连杆311反向转动,这样,第一连杆311即可通过第二连杆312带动驱动轮22反方向转动,从而带动输出轮23和输出轴21沿第二方向转动以实现关门动作。
另外,由于驱动凸轮412和凸轮部3221之间存在死点位置,为了避免驱动凸轮412在于凸轮部3221刚开始接触时就位于死点位置而导致无法驱动凸轮部3221转动,在一些实施方式中,在驱动凸轮412逐渐与驱动滑块42分离的过程中,弹性机构50可驱动驱动滑块42朝驱动组件40所在的一侧运动从而抵持第四连杆322的凸轮部3221以带动凸轮部3221转动,进而使得驱动凸轮412在于凸轮部3221接触时错过凸轮部3221上的死点位置以使得驱动凸轮412能够顺利地带动凸轮部3221转动以实现关门动作。
在一些实施方式中,凸轮部3221上可形成有凹陷,在驱动凸轮412与驱动滑块42逐渐分离后,驱动凸轮412与凸轮部3221上的凹陷抵持从而使得驱动凸轮412能够更好地带动凸轮部3221转动。
另外,可以理解的是,在其它实施方式中,驱动组件40也可不采用上述的驱动凸轮412来进行驱动,而是采用偏心曲柄连杆组来带动驱动凸轮412进行驱动,这样,驱动组件40和连杆组件30组成纯连杆组,可增加驱动的刚性。
请参阅图7,在某些实施方式中,在门体300处于关闭状态下,驱动凸轮412在转动过程中能够至少部分地伸出至基体10外以抵持门体300或者机体200从而驱动门体300相对机体200转动。
如此,在需要进行开门动作时,驱动凸轮412可先抵持门体300或者机体200以将门体300打开一条缝隙以便后续通过连杆组件30来进行开门动作。
具体地,在冰箱等家用电器中,在门体300和机体200上通常都设置有磁吸密封条来保证门体300和机体200的之间的密封效果,而两者之间具有较大的吸力,并且,由于机体200内部可能存在气体的流动,这样也可能形成负压而导致门体300被紧紧地吸附在机体200上,在这样的情况下,在开门时,可先通过开关门装置100的驱动凸轮412来将门体300顶开一条缝隙,以便进行后续的开门流程。
可以理解,在这样的情况下,由于在连杆组件30执行开门动作前门体300就已经打开了一条缝隙,因此,在关门过程中,连杆组件30的关门行程可以设置成比开门形成略大,这样,在关门时可以将门体300完全关死。当然,在一些实施方式中,也可以是将开门形成和关门形成设置成一样,在 连杆组件30进行了关门动作后,门体300可依靠门体300和机体200之间的磁性来实现将门体300完全关闭,具体在此不作限制。
可以理解的是,在这样的实施方式中,在开关门装置100安装在门体300上时,驱动凸轮412则是伸出基体10外抵持机体200从而将门体300顶开,在开关门装置100安装在机体200上时,驱动凸轮412则是伸入基体10外抵持门体300从而将门体300顶开。
在某些实施方式中,开关门装置100还可包括电池80,电机可安装在机壳12上,电池80用于驱动组件40的驱动电机411进行供电,盖板13盖设在电池80上。如此,可通过设置单独供电的电源来给驱动组件40进行供电。
下面,综合上述内容,以将开关门装置100安装在门体100上为了对本申请的电器设备1000的开门和关门流程进行详细介绍,具体地,本申请实施方式的电器设备1000具有自动开门、自动关门、手动开门和手动关门四种模式,一下对四种模式进行介绍。
在自动开门模式下,请参阅图6至图8,图6是开关门装置100基本处于关门状态时的状态示意图,图7是开关门装置100处于开门过程中的状态示意图,图8则是开关门装置处于开门状态时的状态示意图。在图6的基础上,在需要进行自动开门时,驱动电机411带动驱动凸轮412转动,驱动凸轮412转动至图7所述的位置,驱动凸轮412与机体200相抵持,门体300被顶开。随后,驱动凸轮412继续转动,转动一定角度后与驱动滑块42相接触,驱动凸轮412驱动驱动滑块42按照基体10上的滑槽121进行定向滑动,驱动滑块42在滑动时带动第一连杆311进行转动,第一连杆311通过第二连杆312带动驱动轮22转动,驱动轮22带动输出轮23和输出轴21转动,输出轴21则带动门体300相对机体200转动以实现开门动作(如图8所示),在驱动滑块42触发基体10上的第一微动开关60后,驱动电机411断电,停止驱动,也即从图6所示的状态切换至图8所示的状态。
在自动关门模式下,驱动电机411继续驱动驱动凸轮412进行转动,驱动凸轮412与驱动滑块42分离后与关门连杆组32的第四连杆322的凸轮部3221相接触并带动第四连杆322转动,第四连杆322转动时通过第三连杆321带动第一连杆311反向转动,从而通过第二连杆312带动驱动轮22反向转动,驱动轮22则带动输出轮23和输出轴21反向转动,输出轴21则带动门体300反向转动以实现关门动作(如图6所示),直到第四连杆322上的凸轮部3221触发基体10上的第二微动开关70后,驱动电机411断电,停止驱动,也即从图8所示的状态切换至图6所示的状态。
在手动开门时,用户手动拉动门体300,门体300通过输出轴21、输出轮23和驱动轮22逆向带动开门连杆组31转动,开门连杆组31的第一连杆311与驱动滑块42断开接触朝远离驱动滑块42的一侧转动,驱动滑块42受到弹性机构50的作用与驱动凸轮412仅仅相接触,当然,在此过程中,关门连杆组32也会在开门连杆组31的带动下转动,在开门后,关门连杆组32的第四连杆322的凸轮部3221与驱动滑块42共同限制驱动凸轮412的位置。
在手动关门时,用户手动关闭门体300,门体300通过输出轴21、输出轮23和驱动轮22逆向带动开门连杆组31反向转动,开门连杆组31的第一连杆311与朝靠近驱动滑块42的一侧转动以实现手动开门动作。可以理解,在此过程中,第一连杆311组通过第三连杆321带动第四连杆322转动,在门体300关闭后,第四连杆322上的凸轮部3221与第二微动开关70接触。
可以理解的是,在本申请中,电器设备1000可以自动开关模式,手动开关模式,手动开们+自动关们模式,手动关门+自动开门模式。
实施例二:
请参阅图9,本申请实施方式的电器设备1000包括机体200、门体300和本申请实施方式的开关门装置100,门体300可转动地设置在机体200上,开关门装置100可安装在机体200的顶部,开关门装置100用于驱动门体300在机体200上转动以实现门体300的开启和关闭。
请参阅图10-图13,本申请实施方式的开关门装置100可包括基体10、输出组件20、连杆组件30以及驱动组件40。基体10可固定安装在电器设备1000的机体200上。输出组件20可包括输出轴21,输出轴21与基体10可转动地连接,输出轴21用于与电器设备1000的门体300连接,门体300可转动地安装在机体200上。连杆组件30可转动地安装在基体10上,并且,连杆组件30与输出组件20铰接。
驱动组件40可包括驱动部件41和滑块42,驱动部件41安装在基体10上,滑块42能够相对基体10滑动,滑块42还与连杆组件30铰接,驱动部件41用于驱动滑块42相对基体10滑动以带动连杆组件30动作从而带动输出轴21转动以带动门体300相对机体200转动。
可以理解,目前,随着家电智能化设计的发展,智能化设计使冰箱与消费者日常生活更加密切,给消费者日常生活带来便利。在相关技术中,大多数冰箱开门方式均为传统方式,需手拉动门体开门,当用户双手持物品时操作十分不方便。
在本申请实施方式的开关门装置100和电器设备1000中,开关门装置100可安装在电器设备1000的机体200上,输出轴21与基体10转动连接,门体300转动安装在机体200上,驱动组件40的驱动部件41可驱动滑块42滑动从而带动连杆组件30动作,连杆组件30在动作时可带动输出轴21转动,从而带动门体300转动。如此,可将开关门装置100应用在冰箱等电器设备1000中,在用户不便于手动拉开门体300时,开关门装置100可通过驱动部件41可驱动滑块42滑动从而驱动连杆组件30动作来带动输出轴21转动进而带动电器设备1000的门体300转动以实现门体300的开启和关闭,提高了使用的便利性。
具体地,本申请实施方式的电器设备1000包括但不限于冰箱等家用电器,电器设备1000也可以是任何具有门体300和机体200且具备门体300开关功能的其它电器设备1000,具体在此不作限制。
在本文中,主要以电器设备1000为冰箱为例进行说明,冰箱可以是单开门冰箱,也可以是双开门冰箱,在此不作限制。以单开门冰箱为例,机体200开设有用于存储物品的储物腔室,在一个例子中,储物腔室可为冷藏腔室和冷冻腔室等。可以理解的是,在本申请实施方式中,门体300的一侧则通常是通过转轴与机体200铰接在一起从而使得门体300能够相对机体200转动以实现开门和关门,输出轴21则可与门体300上的转轴固定连接在一起或者是通过其它的传动组件连接在一起,在输出轴21转动时可带动门体300相对机体200转动。
请参阅图10-图13,在一些实施方式中,基体10可包括固定板11和机壳12,机壳12罩设在固定板11上,驱动组件40、输出组件20和连杆组件30均可安装在固定板11上,机壳12罩设输出组件20和连杆组件30。滑块42与固定板11滑动连接。如此,将开关门装置100的所有零部件都安装在基体10内,基体10可以将开关门装置100作为一个完整的模块安装在电器设备1000的机体200上,而无需在机体200上增设其它的结构,便于拆卸,能够兼容不同的机型,通用性高。
另外,基体10作为整个开关门装置100的承载主体和安装主体,为了保证支撑和安装的稳定性,基体10的固定板11和机壳12均可采用强度较高的金属材料制成,在一个可能的实施方式中,基体10可采用轻质铝合金材料支撑。当然,在一些实施方式中,基体10也可以采用强度较高的非金属材料制成,具体在此不作限制,只需要满足安装要求即可。当然,可以理解的是,在一些实施方式中,基体10也可以仅仅只是包括固定板11而不具有机壳12,具体设置可根据实际情况进行选择,在此不作具体限制。进一步地,请参阅图9,在本申请中,开关门装置100可作为一个单独的模块安装在机体200的顶部靠近门体300的转轴所在的位置,输出轴21可与门体300上的转轴部同轴固定设置,这样,在输出轴21转动时,由于输出轴21与门体300固定连接,输出轴21传递出的扭矩会带动整个门体300相对机体200以实现自动开关门动作。当然,可以理解的是,在一些实施方式中,也可以在机体200上设置用来传动的齿轮,在门体300的转轴上也可设置与机体200上的齿轮啮合的齿轮,这样,在输出轴21转动时,输出轴21会带动机体200上的齿轮转动,从而带动门体300相对机体200转动,具体设置方式可根据实际需求进行选择,在此不作限制。
请参阅图10至图13,在某些实施方式中,输出组件20还包括输出轮23和驱动轮22,驱动轮22可转动地安装在基体10上,输出轮23也可转动地安装在基体10上。
连杆组件30与驱动轮22铰接,连杆组件30与驱动轮22的铰接点与驱动轮22的转动中心偏心设置。驱动轮22与输出轮23动力连接,输出轴21与输出轮23固定连接,滑块42用于驱动连杆组件30动作以带动驱动轮22转动从而带动输出轮23和输出轴21转动。
如此,在连杆组件30动作时,连杆组件30会带动驱动轮22转动,驱动轮22会带动输出轮23转动,输出轮23则通过输出轴21带动门体300在机体200上转动以实现开关门动作。
具体地,在本申请的实施方式中,“输出轮23与驱动轮22动力连接”可以理解为两者直接接触 以实现动力传递或者是两者通过中间的连接元件实现间接接触以实现动力的传递。在一个可能的实施方式中,输出轮23和驱动轮22可均为齿轮,两者直接啮合在一起或者是通过中间传动齿轮来实现间接啮合,在另外的实施方式中,输出轮23和驱动轮22也可为带轮,两者之间通过传动带实现传动。另外,在一些实施方式中,输出轮23和驱动轮22也可均为链轮,两者之间通过传动链来实现动力的传动。在本申请中并不对输出轮23和驱动轮22之间的传动方式进行限制,只需要两者之间能够进行动力传递即可。
在一些实施方式,输出组件20还可包括第一轴承24和第二轴承(图未示出),驱动轮22的中心转轴部分可与第一轴承24连接从而将驱动轮22可转动地支撑在基体10上以保证驱动轮22转动的稳定性,输出轮23的中心转轴部分可与第二轴承连接从而将输出轮23可转动地支撑在基体10上以保证驱动轮22转动的稳定性,输出轴21则可与输出轮23的中心转轴部分同轴固定连接在一起,也即是说,输出轴21是跟随输出轴21同轴转动,“同轴”可以理解为两者的轴线完全重合或者是两者的轴线之间的间隔距离处于装配误差的允许范围内,在下文若出现相同或者类似的说明书,也可参照此处理解。在本申请中,对于第一轴承24和第二轴承的类型不作具体限制,其可为滚珠轴承、圆锥滚子轴承,也可以是圆柱滚子轴承等等,只需要能够满足支撑要求即可。
可以理解的是,在本申请的实施方式中,连杆组件30与驱动轮22两者之间的铰接点与驱动轮22的转动轴线的中心偏心可以保证连杆组件30在转动时能够带动驱动轮22转动。
较佳地,在本申请中,连杆组件30与驱动轮22的铰接点可位于驱动轮22的外围边缘位置。铰接点与驱动轮22的中心之间的距离越远越好。这样,连杆组件30可通过较小的转动形成来带动驱动轮22实现较大的转动行程,也即是说,通过连杆组件30和驱动轮22的配合设置可以做到在较小的体积内形成较大的门体300开合行程。
请参阅图10-图13,在某些实施方式中,输出轮23和驱动轮22均为齿轮,输出轮23和驱动轮22动力连接。
如此,可通过齿轮传动的方式来实现驱动轮22和输出轮23之间的动力传递,齿轮传动的稳定性较高,可以提供较高的扭矩,从而保证门体300开合的稳定性。
具体地,在图10-图13所示的实施方式中,驱动轮22和输出轮23均为外齿轮,两者直接啮合在一起。可以理解的是,为了使得驱动轮22在转动较小的形成能够使得门体300具有更大的转动行程,在本申请中,驱动轮22的分度圆直径要大于输出轮23的分度圆直径,驱动轮22的齿数要大于输出轮23的齿数,也就是说,驱动轮22的径向尺寸要大于输出轮23的径向尺寸。这样,在驱动轮22转动较小的角度时,输出轮23在驱动轮22的带动下能够转动更大的角度,从而实现大行程的门体300开合,可以做到在较小的体积内形成较大的门体300开合行程,示例性地,在一个例子中,在驱动轮22转动°时,输出轮23在驱动轮22的带动下则可转动°甚至更大,从而使得门体300也能够转动相应的角度。
当然,可以理解的是,在一些实施方式中,驱动轮22和输出轮23也可以不是直接啮合在一起,而是在基体10上还设置有可以转动的传动齿轮,传动齿轮的数量可以为一个也可以为多个,驱动轮22和输出轮23之间可以通过一个或者多个传动齿轮依次啮合在一起以实现动力的传递,具体在此不作限制。
另外,还可以理解的是,在一些实施方式中,驱动轮22和输出轮23也可均为带轮,输出组件20还可包括传动带,传动带绕设在输出轮23和驱动轮22上。如此,通过带传动的方式也同样能够实现动力的传递。
具体地,在这样的实施方式方式中,传动带可以为平带也可以为V带以实现平带传动护着V带传动。同理,为了保证能够驱动轮22能够以较小的角度来带动输出轮23转动较大的角度以实现门体300的大行程开合,在这样的实施方式中,驱动轮22的直径要大于输出轮23的直径。
请参阅图12-图15,在某些实施方式中,连杆组件30包括第一连杆31、第二连杆32和第三连杆33。
第一连杆31的一端与滑块42铰接,另一端与第二连杆32铰接,第二连杆32可转动地安装在基体10上,第二连杆32的一端与第一连杆31铰接,另一端与第三连杆33铰接,第三连杆33的一端 与第二连杆32铰接,另一端与输出组件20铰接,在滑块42滑动时,滑块42通过第一连杆31带动第二连杆32转动,第二连杆32带动第三连杆33动作从而带动输出轴21转动。
如此,只需要通过驱动部件41来驱动滑块42沿不同的方向滑动即可通过第一连杆31来带动第二连杆32沿不同的方向转动以实现门体300的开启和关闭。同时,在这样的情况下,开门动作和关门动作均可由第三连杆33、第二连杆32和第一连杆31来执行,而无需设置额外的关门驱动结构。
具体地,在这样的实施方式中,第三连杆33远离第二连杆32的一端与驱动轮22铰接,且两者的铰接点与驱动轮22的转动中心偏心。
请参阅图12-图15,图12和图13是开关门装置100处于关门状态时的状态示意图,图14和图15是开关门装置100处于关门状态时的状态示意图。
在开门时,滑块42在驱动部件41的带动下滑动,由于第一连杆31与滑块42铰接,在滑块42滑动时会带动第一连杆31运动,第一连杆31则通过第二连杆32和第三连杆33带动驱动轮22转动,驱动轮22则带动输出轮23和输出轴21转动,从而带动门体300转动以实现开门动作(即从图12和图13所示的状态运动至图14和图15所示的状态)。在关门时,滑块42在驱动部件41的带动下反向滑动,第一连杆31则带动第二连杆32反向转动,从而通过第三连杆33带动驱动轮22反向转动,输出轮23和输出轴21在驱动轮22的带动下也反向转动,输出轴21则带动门体300反向转动以实现关门动作(即从图14和图15所示的状态运动至图12和图13所示的状态)。
可以理解的是,在一些实施方式中,连杆组件30也不仅限于包括上述的三根连杆。具体地,在一些情况下,在第三连杆33与第二连杆32之间还可连接设置有其它的连杆。在一个可能的实施方式中,可在第三连杆33和第二连杆32之间还连接设置一根连杆,该连杆的两端分别第二连杆32与第三连杆33铰接,在第二连杆32动作时,该连杆在第二连杆32的带动下动作,从而带动第三连杆33动作以执行开关门动作。可以理解的是,在本申请中,只需要能够带动输出组件20的驱动轮22正向和反向转动即可,具体对连杆的数量不作限制,当然,为了节约制造成本,连杆组件30的连杆的数量越少越好。
请参阅图12-图15,在某些实施方式中,驱动组件40还可包括滑动轴412,滑动轴412可滑动地安装在基体10上,滑块42固定安装在滑动轴412上,滑动轴412与驱动部件41连接,驱动部件41用于驱动滑动轴412相对基体10滑动以带动滑块42相对基体10滑动。
如此,滑动轴412与滑块42固定连接,驱动部件41可通过带动滑动轴412滑动从而带动滑块42运动以实现对连杆组件30的驱动。
具体地,在这样的实施方式中,滑动轴412可为光轴,光轴可穿设滑块42且与滑块42固定连接,光轴的直径在此不作限制,在一个例子中,光轴的直径可为6mm。如图12-图15所示,在基体10的固定板11上设有固定块111,固定块111的数量可为两个,两个固定块111间隔设置,滑动轴412穿设两个固定块111且与滑动轴412滑动连接,两个固定块111可对滑动轴412进行良好的支撑,同时也能够对滑动轴412的滑动进行导向,在这样的情况下,滑块42可安装在滑动轴412上且位于两个固定块111之间,两个固定块111可对滑动轴412和滑块42的运动行程进行限制。
当然,可以理解的是,在一些实施方式中,也可不设置滑动轴412,而是直接在基体10上设置导轨或者滑槽来引导滑块42滑动,在一个可能的实施方式中,可在固定板11的顶部安装滑轨,滑块42与滑轨配合,在这样的情况下,驱动部件41可直接与滑块42连接,驱动部件41驱动滑块42在滑轨上滑动从而带动连杆组件30的第一连杆31动作以实现开门和关门动作。
请参阅图12-图15,在某些实施方式中,驱动部件41可包括驱动电机411,驱动电机411包括主体4111和与主体4111滑动连接电推杆4112,主体4111与基体10固定连接,电推杆4112与滑块42固定连接,在电推杆4112相对主体4111滑动时,电推杆4112能够带动滑块42相对基体10同步滑动。
如此,驱动电机411可直接通过电推杆4112的直线运动来带动滑块42滑动从而实现开关门动作。
具体地,在这样的实施方式中,驱动电机411可为直线驱动电机,例如,笔形驱动电杆,在这样的情况下,驱动电机411的电推杆4112可直接进行直线运动从而带动滑块42滑动。可以理解,驱动电机411的电推杆4112相对于主体4111的滑动方向与滑块42相对基体10的滑动方向相同。驱动电 机411可通过导线连接开关门装置100的电池或者是直接与电器设备100的控制器或者控制电路板电性连接。
进一步地,在某些实施方式中,驱动组件40还可包括滑动轴412,滑动轴412可滑动地安装在基体10上,滑块42固定安装在滑动轴412上,驱动部件41还包括连接件413,连接件413固定连接电推杆4112和滑动轴412,电推杆4112能够通过连接件413带动滑动轴412相对基体10滑动。
如此,可通过连接件413将滑动轴412与电推杆4112固定连接在一起,在电推杆4112运动时,电推杆4112可通过连接件413带动滑动轴412同步滑动从而带动滑块42滑动。
具体地,正如上文所述的,滑动轴412的设置与上文的设置方式一样。连接件413可为双轴固定片,如图12和图14所示,双轴固定片上可开设有两个大小不同的安装孔,滑动轴412和电推杆4112平行,电推杆4112固定安装在双轴固定片的大孔内,滑动轴412则固定安装在双轴固定片的小孔内,这样,在电推杆4112的运动时,电推杆4112可通过双轴固定片带动滑动轴412滑动从而带动滑块42滑动。
当然,可以理解的是,在一些实施方式中,也可以是不设置连接件413和滑动轴412,而是直接将滑块42与电推杆4112连着直接固定连接在一起,例如,可通过焊接或者螺钉固定以及过盈配合等方式将两者固定连接在其。在电推杆4112动作时可同步带动滑块42滑动,具体设置方式在此不作限制。
此外,在某些实施方式中,驱动部件41也可包括驱动电机411和传动机构,驱动电机411连接传动机构,传动机构连接驱动电机411和滑块42,传动机构包括齿轮齿条传动机构或者丝杆螺母传动机构。
如此,可通过传动机构来将电机的转动转化为直线运动从而带动滑块42滑动以带动连杆组件30动作。
具体地,跟上述实施方式不同的是,在这样的实施方式中,驱动电机411可为常用的转子电机,驱动电机411的电机轴可与传动机构连接,可通过传动机构来将电机轴的转动来转换成直线运动从而带动滑块42实现滑动。
在一个可能的实施方式中,传动机构可为齿轮齿条传动机构,在这样的情况下,传动机构可包括齿轮组和齿条,齿条可与滑块42固定连接或者与滑块42一体成型,齿轮组则与驱动电机411的电机轴连接且与齿条啮合,这样,在驱动电机411驱动齿轮组转动时,齿轮组可带动齿条相对基体10滑动从而带动滑块42实现滑动。可以理解的是,在这样的实施方式中,齿轮组可至少包括一个齿轮,在一个可能的实施方式中,在齿轮组只包括一个齿轮的情况下,齿轮可直接与驱动电机411的电机轴固定连接且与齿条啮合,驱动电机411转动时直接通过该齿轮驱动齿条和滑块42相对基体10滑动。又如,在另一个可能的实施方式中,在齿轮组包括两个或者两个以上的齿轮的情况下,多个齿轮可组成变速传动机构,其中,齿轮组的输入齿轮与电机轴连接,输出齿轮则与齿条部啮合,而输入齿轮和输出齿轮两者可以是直接啮合也可以是在两者之间还设置一个或者多个传动齿轮来实现间接传动,具体在此不作限制。
在另一个可能的实施方式中,传动机构可为丝杆螺母传动机构,在这样的情况下,传动机构可包括丝杆和螺母,丝杆可转动地安装在基体10的固定板11上,在一个可能的实施方式中,可通过在固定板11上设置至少两个支撑轴承来对丝杆的转动进行支撑,丝杆可与驱动电机411连接,驱动电机411可驱动丝杆转动,螺母则可固定安装在滑块42上,丝杆穿设螺母,这样,在丝杆转动时,丝杆会驱动螺母和滑块42沿丝杆的轴向方向转动从而带动连杆组件30动作。当然,可以理解的是,在这样的实施方式中,也可以是直接在滑块42上形成有螺纹孔,丝杆则穿设螺纹孔,丝杆与滑块42共同组成丝杆螺母传动机构,具体在此不作限制。
另外,在这样的实施方式中,驱动电机411的电机轴可以是通过联轴器等装置直接与丝杆同轴设置以实现同轴转动,也可以是通过齿轮传动组来实现对丝杆的驱动,在一个可能的实施方式中,在丝杆的一端可安装有齿轮,驱动电机411的电机轴上也安装有齿轮,驱动电机411可通过齿轮之间的啮合来实现对丝杆的驱动。
请参阅图10和图16,在某些实施方式中,开关门装置100还包括离合模块60和输出轴套50, 输出轴套50套设在输出轴21上,输出轴套50用于与门体300固定连接,离合模块60将输出轴21和输出轴套50动力连接,输出轴21转动时通过离合模块60带动输出轴套50转动;
在输出轴套50受到来自门体300且大于预定阈值的扭矩作用时,离合模块60中断输出轴21和输出轴套50之间的动力传动以使输出轴套50能够相对输出轴21自由转动。
如此,可通过离合模块60来实现输出轴套50与输出轴21之间的动力传递和动力中断,从而使得门体300即可实现自动开关门,也可以实现手动开关门。
具体地,在这样的实施方式中,在门体300没有受到来自用户或者外界其它物体的外力或者是受到的力较小时,门体300给输出轴套50施加的扭矩为零或者小于预设阈值,这样,离合模块60保持将输出轴套50与输出轴21动力连接,在这样的情况下,驱动组件40可通过连杆组件30和输出组件20来带动输出轴21转动,从而通过离合模块60来带动输出轴套50转动以实现自动开关门。
在用户需要进行手动开关门时,用户给门体300施加较大的力,门体300将扭矩传递给输出轴套50,在扭矩大于预定阈值时,离合模块60切断输出轴套50与输出轴21之间的动力传动传递,在这样的情况下,输出轴套50可在门体300的带动下自由转动而实现手动开关门,在手动开关门时不会反向带动输出轴21和输出组件20的输出轮23和驱动轮22转动,避免造成卡死。
请参阅图16-图24,在某些实施方式中,离合模块60可包括限位件62、弹性件63和浮动轴套61。
浮动轴套61套设在输出轴21上且与输出轴21固定连接,浮动轴套61和输出轴21能够沿输出轴21的转动轴线相对基体10移动,输出轴套50套设在浮动轴套61外侧,浮动轴套61的周壁底部上形成有第一卡槽611和第二卡槽612,第一卡槽611和第二卡槽612间隔设置,输出轴套50的周壁上设有紧固件51,紧固件51伸入至第一卡槽611内。
限位件62套设在输出轴21上,限位件62沿径向方向形成有限位部622,弹性件63套设在输出轴21上且位于输出轴21的端部和限位件62之间,弹性件63的两端分别与限位件62和输出轴21的端部弹性抵持,输出轴套50上形成有限位槽52,限位部622伸入至第二卡槽612以及限位槽52内,限位部622在弹性件63的作用下与第二卡槽612的内壁抵持以将输出轴21和输出轴套50动力连接(如图16、图20和图21所示);
其中,在驱动组件40驱动输出轴21转动时,浮动轴套61通过限位部622带动输出轴套50转动。
在输出轴套50受到来自门体300且大于预定阈值的扭矩作用时,紧固件51驱动浮动滑块42沿输出轴21的转动轴线向上移动,限位部622滑出第二卡槽612且与浮动轴套61的底部相抵持(如图22至图24所示),从而中断输出轴21和输出轴套50之间的动力传递。
如此,通过浮动轴套61、弹性件63以及限位件62之间的配合连接关系来实现输出轴21和输出轴套50之间的动力连接以及动力中断,从而使得整个开关门装置100能够实现自动开关门和手动开关门。
具体地,请参阅图17,在这样的实施方式中,输出轴21的顶部可安装有浮动挡板64,浮动挡板64沿径向方向形成有止挡部641,在输出轮23上形成有顶部开口的止挡滑槽231,止挡部641与止挡滑槽231配合从而使得输出轮23在转动时可带动输出轴21同步转动,并且也能够使得输出轴21可沿轴向方向向上移动。
进一步地,请参阅图20和图21以及图23和图24,第一卡槽611可为位于浮动轴套61的周壁上且底部开放的槽,第一卡槽611向浮动轴套61的底部方向形成有第一引导弧面6111,紧固件51伸入至第一卡槽611内(如图20所示)。
第二卡槽612也可为位于浮动轴套61的周壁上且底部开放的槽,第二卡槽612向浮动轴套61的底部方向形成有第二引导弧面6121,限位部622在弹性件63的作用下抵持在第二卡槽612内(如图21所示)。
弹性件63可为弹簧等弹性元件,在输出轴21的端部上可设有抵持件,抵持件可以是螺钉或者螺栓等紧固元件,具体地,在输出轴21上开设有螺纹连接孔,抵持件可通过螺纹连接的方式安装在输出轴21的端部,当然,可以理解的是,在一些实施方式中,也可是直接将输出轴的21的端部做成更大的尺寸。
弹性件63套设在输出轴21上,限位件62包括成环状本体621和沿径向方向凸设在环状本体621上的限位部622,限位部622可为限位轴部,环状本体621套设在输出轴21上,弹性件63位于环状本体621和抵持件之间且与两者弹性抵持,弹性件63处于压缩状态,在弹性件63的弹性力作用下,限位件62的限位部622抵持在浮动轴套61上的第二卡槽612内,同时,限位部622还伸入至输出轴套50上的限位槽52内(见图19和图21)。
请参阅图16以及图20-图24,图16、图20和图21为离合模块60将浮动轴套61和输出轴套50动力连接的状态示意图,图14-图16为离合模块60中断浮动轴套61和输出轴套60的动力连接的状态示意图。请参阅图20和图21,在初始状态下,弹性件63给输出轴21以及浮动轴套61施加弹性力,并且限位件62也会受到弹性力,限位部622和浮动轴套61在弹性件63的作用下使得限位部622抵持在第二卡槽612内,并且,限位部622伸入至输出轴套50的限位槽52内并抵持限位槽52的内壁,由此,输出轴套50、浮动轴套61和限位件62保持处于相对稳定的状态。在这样的情况下,在驱动部件41驱动滑块42滑动从而通过连杆组件30带动驱动轮22转动时,驱动轮22会通过输出轮23驱动输出轴21和浮动轴套61转动,浮动轴套61则会通过限位部622带动输出轴套50转动,也即,输出轴套50会跟随浮动轴套61转动,从而实现自动开关门动作。
请参阅图23和图24,在用户需要手动开门或关门时,输出轴套50会受到较大的扭矩作用,在输出轴套50在门体300的带动下转动时,输出轴套50上的紧固件51会通过第一引导弧面611给浮动轴套61施加作用力从而克服弹性件63给浮动轴套61施加的弹性力逐渐将浮动轴套61和输出轴21顶起,同时,由于限位件62的限位部622伸入至限位槽52内,因此,在浮动轴套61向上移动的同时,限位件62也在输出轴套50的作用下沿第二引导弧面6121从第二卡槽612中脱离出来并在弹性件63的作用下与浮动轴套61的底部抵持且沿底部转动(即从图20和图21所示的状态切换至图23和图24所示的状态),在这样的情况下,由于限位件62已经从而浮动轴套61第二卡槽612中脱离,限位件62可自由转动,并且紧固件51也从第一卡槽611内滑出,因此,输出轴套50与浮动轴套61之间动力转动被切断,输出轴套50可以相对输出轴21和浮动轴套61自由转动。
可以理解的是,在这样的实施方式中,“预定阈值”是根据弹性件63给浮动轴套61所施加的作用力来确定的,在门体300给输出轴套50施加的大于预定阈值的扭矩时,紧固件51才会驱动浮动轴套61向上运动从而与输出轴套50分离而无法实现动力传递(即中断两者的动力连接),在门体300不受力或者受力较小时,门体300传递给输出轴套50的扭矩为零或者是小于预定阈值,在这样的情况下,由于弹性件63的弹性力的存在,限位部622会保持抵持在第二卡槽612内从而保持浮动轴套61与输出轴套50的动力连接。
另外,可以理解,在手动开门后需要进行手动关门时,门体300带动输出轴套50反向转动,输出轴套50带动限位件62和紧固件51转动,在转动至关门位置时,紧固件51转动至第一卡槽611所在的位置,限位部622转动至第二卡槽612所在的位置。这样,浮动轴套61在弹性件63的作用下向下复位使得紧固件51伸入至第一卡槽611内,限位部622卡入至第二卡槽612内(即从图23和图24所示的状态切换至图20和图21所示的状态),此时,关门完毕,用户撤销给门体300施加的力,输出轴套50、浮动轴套61和限位件62恢复至初始状态而保持相对稳定。
在某些实施方式中,开关门装置100还可包括第一微动开关(图未示出)和第二微动开关(图未示出),第一微动开关和第二微动开关可间隔设置在基体10上,第一微动开关和第二微动开关均与驱动组件40电性连接且能够被滑块42触发,在滑块42触发第一微动开关或第二微动开关时,驱动组件40停止工作。
如此,在门体300打开的过程中,在滑块42触发第一微动开关后,表示门体300已经打开到了最大位置,此时,第一微动开关断开驱动组件40的电源,使得驱动组件40停止工作,以避免在门体300打开至最大角度后驱动组件40还在输出转动扭矩而造成堵转卡死。在门体300关闭的过程中,在滑块42触发第二微动开关后,表示门体300已经关闭,此时,第二微动开关断开驱动组件40的电源,使得驱动组件40停止工作,以避免在门体300完全关闭后驱动组件40还在输出转动扭矩而造成堵转卡死。
具体地,在这样的实施方式中,第一微动开关和第二微动开关可间隔设置在滑块42的的滑动路 径上,在滑块42朝第一微动开关滑动时,开关门装置100执行开门动作,在滑块42触发第一微动开关时则表示开门结束,停止工作。在滑块42朝第二微动开关滑动时,开关门装置100执行关门动作,在滑块42触发第二微动开关时表示关门结束,停止工作。
当然,可以理解的是,在其它实施方式中,第一微动开关和第二微动开关也可以是设置在第二连杆32的转动轨迹路径上,两者可由第二连杆32来进行触发,具体在此不作限制。
在某些实施方式中,开关门装置100还可包括电池(图未示出),电池可安装在基体10上,电池用于驱动组件40的驱动电机411进行供电。如此,可通过设置单独供电的电源来给驱动组件40进行供电。当然,在其它实施方式中,也可不设置电池,而是直接将驱动电机411的电源线与电气设备1000内部的电路连接。
下面,综合上述内容,对本申请的电器设备1000的开门和关门流程进行详细介绍,具体地,本申请实施方式的电器设备1000具有自动开门、自动关门、手动开门和手动关门四种模式,一下对四种模式进行介绍。
请参阅图12至图13,图12和图13是开关门装置100基本处于关门状态时的状态示意图,在关门状态下,驱动电机411的电推杆4112基本收容在主体4111内,并且,离合模块60将输出轴套50与输出轴21动力连接(输出轴21与输出轮23连接,紧固件51位于第一卡槽611内,限位部622抵持在第二卡槽612和限位槽52内,即如图20和图21所示)。
在需要自动开门时,驱动电机411的电推杆4112初步伸出并抵持门体300以将门体300顶开一条缝隙并进一步持续伸出,在电推杆4112伸出的过程中,电推杆4112通过连接件413带动滑动轴412滑动,进而带动滑块42运动,滑块42动作时带动第一连杆31运动,第一连杆31则通过第二连杆32和第三连杆33带动驱动轮22转动,驱动轮22转动时带动输出轴21转动,输出轴21则通过浮动轴套61、限位件62的限位部622带动输出轴套50同步转动以实现开门动作,在驱动滑块42触发基体10上的第一微动开关后,驱动电机411断电,停止驱动,也即从图12和图13所示的状态切换至图14和图15所示的状态。
在需要自动关门时,驱动电机411的电推杆4112逐渐缩回至本体内从而带动滑块42反向滑动,滑块42则通过第一连杆31带动第二连杆32反向转动,第二连杆32则通过第三连杆33带动驱动轮22反向转动,输出轴21也反向转动转动,输出轴21通过浮动轴套61、限位件62的限位部622带动输出轴套50同步反向转动以实现自动关门动作,直到滑块42触发第二微动开关后,驱动电机411断电,停止驱动,也即从图14和图15所示的状态切换至图12和图13所示的状态。
在手动开门时,用户手动拉动门体300,门体300给输出轴套50施加扭矩,浮动轴套61在输出轴套50上的紧固件51的带动下被顶起,限位件62的限位部622从第二卡槽612内分离从而断开输出轴套50与浮动轴套61之间的动力传动(即从图20和图21所示的状态切换至图23和图24所示的状态不),此时,输出轴套50可自由转动而不会带动输出轴21以及输出轮23逆向转动。
在手动开门后需要进行手动关门时,门体300带动输出轴套50反向转动,在关门完成后,紧固件51运动至第一卡槽611所在的位置,限位部622运动至第二卡槽612所在的位置,浮动轴套61则在弹性件63的作用下向下复位以使得紧固件51第一卡槽611,并使得限位部622抵持在第一卡槽611和限位槽52内从而实现输出轴套50和浮动轴套61的动力连接(即从图23和图24所示的状态切换至图20和图21所示的状态不),以便后续可以通过开关门装置100执行自动开门动作。
可以理解的是,在手动开门后需要进行自动关门时,由于在手动开门后浮动轴套61与输出轴套50之间没有动力传动,因此,在这样的情况下,可先将电推杆4112驱动至自动开门后所在的位置,这样,浮动轴套61会在输出轴21的带动下转动使得第一卡槽611与紧固件51向对应,第二卡槽612与限位件62的限位部622相对应,浮动轴套61则在弹性件63的作用下向下复位以使得紧固件51第一卡槽611,并使得限位部622抵持在第一卡槽611和限位槽52内从而实现输出轴套50和浮动轴套61的动力连接,以便后续可以通过开关门装置100执行自动关门动作。
综上,在一个实施方式中,本申请实施方式的开关门装置100可包括基体10、输出组件20、连杆组件30以及驱动组件40。基体10可安装在电器设备1000的机体200或者是门体300上。输出组件20可包括输出轴21,输出轴21与基体10可转动地连接,输出轴21用于与电器设备1000的门体 300或者机体200连接,门体300可转动地安装在机体200上。连杆组件30可转动地安装在基体10上,并且,连杆组件30与输出组件20铰接,驱动组件40用于驱动连杆组件30动作以带动输出轴21转动,从而带动门体300相对机体200转动。
