具体实施方式
下面将结合附图,对本公开实施方式中的技术方案进行清楚、完整地描述。显然,所描述的实施方式仅仅是本公开的一部分实施方式,而不是全部的实施方式。基于本公开中的实施方式,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施方式,都属于本公开保护的范围。

下面结合附图并参考具体实施方式描述本公开的技术方案。
参见图1和图2,依据本公开的一个或多个实施方式提供了一种开关门装置,其安装到电器设备的箱体12上,并与电器设备的门体13连接。开关门装置通过驱动门体13使门体13相对于箱体12偏转,以实现箱体12的封闭和开启,从而提升了操作便捷性。开关门装置还能够在使门体13到达预设开度后维持使门体13维持在当前位置,以便于在箱体12内拿取或者存储物品,从而提升了使用舒适性,也能够避免因门体偏转关闭而造成人员碰撞的安全风险。
依据本公开的一个或多个实施方式的开关门装置主要应用在电器设备上,用于自动打开或者是关闭门体13,开关门装置在接收到开门信号后可自动打开门体13;在一些实施方式中,开门信号可以是用户触发的,也可以是电器设备自身触发的。在另外一些实施方式中,开关门装置在接收到关门信号后可自动关闭门体13;关门信号可以是用户触发的,也可以是电器设备自身触发的。
本公开的一个或多个实施方式中,开关门装置包括:驱动机构100、离合器200、联动齿轮300、转门机构400以及顶门机构500。通过驱动机构100依次驱动离合机构200、联动齿轮300从而带动转门机构400和顶门机构500,以实现顶门操作和转动门操作,从而可实施开关门过程。在一些实施方式 中,离合器200能够可选择的切断或者连通驱动机构100与联动齿轮300之间的传动结构,从而实现驱动机构100和下游的联动齿轮300、转门机构400以及顶门机构500组成的开关门执行机构之间的传动控制,灵活实现自动开关门和手动操作切换,可改善手动开关门与开关门装置相互干涉的问题,提升使用便捷性,顺畅性和安全性。
在一些实施方式中,可设置底座900作为开关门装置的承载主体,分别承载容纳上述各功能组件,从而可以整体安装到如单开门、双开门冰箱等电气设备上,具备良好的扩展和兼容性能。值得说明的是,底座900可以配置上盖或者其他具备覆盖约束范围的壳体结构,将上述各功能组件保护在内。
具体来说,驱动机构100和离合器200可固设在底座900上,联动齿轮300作为衔接上下游组件的传动组件,转动地设置在底座900上,通过离合器200与驱动机构100建立可控制通断的传动连接关系,根据设定的规则模式,灵活切断和保持联动齿轮300与驱动机构100的传动连接状态。
顶门机构500与联动齿轮300连接,从而在联动齿轮300的转动的情况下,能够带动顶门机构500动作,以实现顶推门体13或者复位;通过顶门机构500推顶门体13,能够直接作用在门体13上,突破门体13与箱体12之间的吸附力等开门阻力,降低开门的难度。在顶门机构500将门体13相对于箱体12顶开一定角度后,转门机构400继续转动门体13,使门体13转动并打开到更大的开度,便于存取物资。
转门机构400与联动齿轮300连接,并与门体13活动连接,从而能够在联动齿轮300转动时,转门机构400随着联动齿轮300动作,以转动门体13,从而实现开关门操作。
在一些实施方式中,可通过驱动位置和方式的布置将顶门机构500与转门机构400的动作在时序上进行配合设计。在开门过程中,驱动机构100通过离合器200建立并保持与联动齿轮300的传动连接关系,驱动联动齿轮300正转,先由顶门机构500顶开门体13到一定角度之后,转门机构400接力继续转动门体13到预设的开度位置,以形成大力道小角度顶门和小力道大角度转门的接力开门模式,能够在降低开门难度的同时提高开门便捷性。在关门过程中,联动齿轮300反转,由转门机构400带动门体13转动,逐渐缩小门体13与箱体12的距离,直至门体13关闭在箱体12上,期间顶门机构500在联动齿轮300的带动下复位,以备下次开门操作。
也就是说,动作时序是指先通过顶门机构500用较大力道顶开较小角度,再通过转门机构400带动门体13转动较大角度。通过上述动作时序设计既能够降低开门难度又能够提升开门便捷性的效果,同时能够一定程度上降低转门机构400在整体结构强度以及局部区域的强度要求。上述动作时序设计能够有效保护转门机构400的结构稳定性,避免在仅通过转门机构400突破开门阻力时转门机构400受到较大的反作用力影响,从而能够通过合理的动作时序设计能够保证整体结构的稳定性和功能的稳定性。
值得说明的是,转门机构400和顶门机构500也可以不设置动作时序的先后顺序。
另一方面,离合器200能够灵活地建立或者中断驱动机构100与联动齿轮300的传动连接关系,从而可在开门到位后即时切断传动连接关系,从而门体13的后续开合转动将不会与驱动机构100构成干涉,能够通过便捷的实施手动开关门;相类似的,也可以在门体13关闭到位后即时切断传动连接关系,以便于实施手动开关门。
综上所述,在本公开的一个或多个实施方式中,通过驱动机构100经由离合器200和联动齿轮300驱动顶门机构500和转门机构400,实现由一套驱动机构100同时驱动顶门机构500和转门机构400,简化开关门装置的整体结构规模;并能够通过离合器200的动作控制,实现联动齿轮300与驱动机构100之间的传动连接的通断控制,从而能够降低手动开关门与驱动机构100的干涉,降低开关门装置损坏的风险,保证开关门装置的结构稳定性和可靠性;通过顶门机构500和转门机构400的功能划分和配合,实现大力道小角度的顶门操作与小力道大范围的转门操作接力开门模式,一定程度上降低开门难度,在提高开关门装置结构稳定性的同时保证开关门操作的便捷性和舒适性。

通过第一传动组件210和第二传动组件220的接合与分离实现驱动机构100和联动齿轮300的接合和分离,从而控制驱动机构100与门体13之间的连接和分离状态;通过离合器200的动作降低手动操作门体13与驱动机构100自动开关门体之间的干涉风险,提升操作便捷性和安全性。
为了实现第一传动组件210和第二传动组件220之间的可分离连接,离合器200还可包括传动连接组件230以及相配合的离合顶推组件240。在一些实施方式中,传动连接组件230可以与第二传动组件连接220,通过离合顶推组件240推动传动连接组件230,使传动连接组件230与第一传动组件210分离或者连接,从而实现第一传动组件210和第二传动组件220的连接和分离。
传动连接组件230作为第一传动组件210和第二传动组件220的连接件,本身可相对于第一传动组件210移动,通过推顶传动连接组件230移动,建立或者解除传动连接组件230与第一传动组件 210之间的连接关系,实现第一传动组件210和第二传动组件230的连接和分离。离合顶推组件240用于实施对传动连接组件230的推顶操作。
参见图4、图5和图12,在一些实施方式中,离合顶推组件240可包括顶推套241和推杆242。顶推套241连接在传动连接组件230上,推杆242用于推动顶推套241,能够推动传动连接组件230,使得传动连接组件230能够顺利实施与第一传动组件210的连接和断开操作。

在一些实施方式中,可将连接端231移动地设置在第二传动组件220上,使得连接端231能够同时相对于第一传动组件210和第二传动组件220移动,从而使第一传动组件210和第二传动组件220处于相对稳定的位置和姿态,尽可能不产生非传动操作方向上的移动,便于与上下游的设备保持稳定的连接,从而维持工作状态的稳定。
参见图6和图7,在一些实施方式中,可在第一传动组件210上开设卡槽211,适配卡嵌固定连接端231,并且能够顺畅地实现连接端231脱离卡槽211的操作,保证离合操作的稳定性和可靠性。
参见图7,在一些实施方式中,第一传动组件210可以设置成第一传动齿轮212,通过齿轮啮合传动的方式传递驱动力。考虑到齿轮绕其轴线转动的工作方式,可将卡槽211设置在第一传动齿轮212的轴向端面上,便于建立连接端231与第一传动齿轮212的连接状态和解除连接状态,且降低对其转动和齿部啮合的工作状态的影响。
值得说明的是,为了配合第一传动齿轮212的工作姿态,第二传动组件220的运动方式也可以设置成类似第一传动齿轮212的绕一轴转动的方式,从而实现同步转动传动。
参见图8,在一些实施方式中,可将第二传动组件220设置第二传动齿轮222,并可将第一传动齿轮212与第二传动齿轮222设置成同轴转动的结构形式;连接端231设置在第二传动齿轮222上,通过推动顶推端232,、连接端231能够与第一传动齿轮212的连接,使得第一传动齿轮212和第二传动齿轮222连接并同步转动,建立连通的驱动力传递路径。
参见图4、图5、图13和图14,在一些实施方式中,为了实现第一传动齿轮212和第二传动齿轮222的转动需求,可在底座900上设置转轴结构,引导第一传动齿轮212和第二传动齿轮222装配和转动。具体来说,可在底座900上设置共用转轴920,将第一传动齿轮212和第二传动齿轮222的沿轴向套接在共用转轴920上,保证齿轮转动的功能稳定。
在一些实施方式中,可将共用转轴920设置成变截面轴,自底座900向上依次布置的支撑柱921和转轴柱922,支撑柱921的直径大于第二传动齿轮222上开设的轴孔的孔径,转轴柱922的直径可适配第二传动齿轮222的轴孔的孔径,从而第二传动齿轮222可搁置在支撑柱921上,并套接在转轴柱922上,使得第二传动齿轮222离底座900一定高度,并可稳定转动。第一传动齿轮212可叠置在第二传动齿轮222上,并套接在转轴柱922上实现转动。
在一些实施方式中,连接端231可固设于第二传动齿轮222的轴向端面上,通过推动顶推端232,实现将第二传动齿轮222整体推向或推离第一传动齿轮212,使得连接端231与卡槽211嵌合或者自卡槽211脱离。整体操作简单,且结构件的成型相对简洁,装配操作也简洁高效。
参见图8,在一些实施方式中,可在第二传动齿轮222上设置卡孔221,且连接端231可移动地嵌设在卡孔221内,从而推动顶推端232,使得连接端231相对于卡孔221并靠近第一传动齿轮212移动,进而卡入上述卡槽211内,以建立第一传动齿轮212和第二传动齿轮222的连接。
在连接端231自卡槽211脱离时,连接端231也相对卡孔221移动;过程中,传动连接组件230的移动操作对第一传动齿轮212和第二传动齿轮222的位置和姿态的影响会较低,便于保持其转动的位置和姿态,有助于维持装置的工作状态和运行可靠性。
在一些实施方式中,也可将卡槽211设置成轴向贯穿第一传动齿轮212的通孔,从而能够避免连接端231直接推顶卡槽211的槽底,造成不必要的扰动,保持第一传动齿轮212转动过程的稳定性。
在一些实施方式中,考虑到第一传动齿轮212和第二传动齿轮222的转动的工作方式,为了增加连接端231卡入到卡槽211的效率,可将连接端231设置成多个连接臂2311,相应地,卡槽211的数量可与连接臂2311的数量相同,也可以是更多,以降低连接臂2311卡入卡槽211的难度。
值得说明的是,卡槽211的转动轨迹应当与连接臂2311的移动轨迹相交,从而使得连接臂2311可以嵌入卡槽211内。
在一些实施方式中,连接臂2311到第二传动齿轮222的转轴轴线的距离与卡槽211到第一传动齿轮212的转轴轴线的距离应当一致,从而在轴线方向上,卡槽211与连接臂2311能够稳定卡合和 脱离。从而使得对顶推端231的顶推力沿第二传动齿轮222的转轴轴线方向,其加工和装配时均可以转轴轴线为参考,便于离合顶推组件240的设置,装配和顶推操作。
值得说明的是,连接臂2311到第二传动齿轮222的转轴轴线的距离与卡槽211到第一传动齿轮212的转轴轴线的距离也可以不一致,仅需要保证卡槽211的转动轨迹应当与连接臂2311的移动轨迹相交,并且在连接臂2311和卡槽211均有多个的时候,合理设置多个连接臂2311的间隔和多个卡槽211间的间隔,以避免无法稳定嵌入。
在一些实施方式中,可将多个连接臂2311等间隔布置在一个圆形轨迹上,相应地,多个卡槽211也可等间隔布置在上述圆形轨迹上,从而能够形成良好适配的位置和间隔布置模式,便于卡嵌。
值得说明的是,为了增加连接臂2311与卡槽211适配嵌合的效率,可适当增加卡槽211的数量,可将卡槽211的数量设置成连接臂2311数量的整数倍,从而在等间隔布置卡槽211和连接臂2311的情况下,能够大幅增加连接臂2311与卡槽211适配嵌合的效率。
在一些实施方式中,多个连接臂2311也可以设置在多个圆形轨迹上,相应地,在第一传动齿轮212应当参考圆形轨迹,设置适配数量的卡槽211,以保证能够稳定嵌合。
在一些实施方式中,传动连接组件230的顶推端232直接与顶推套241连接,考虑到顶推方向与第二传动齿轮222和第一传动齿轮212的转动方向垂直,可将传动连接组件230设置成绕第二传动齿轮222的转轴转动的形式;顶推端232转动地设置在顶推套241上,从而可兼顾传动连接组件230的转动和轴向移动的工作状态。
具体可将传动连接组件230的顶推端232包括环形座2321,且环形座2321可转动地连接在顶推套241上,实现传动连接组件230的转动和轴向移动的工作状态。另一方面,顶推套241仅需要轴向顶推环形座2321即可,不必考虑其转动状态,极大地简化了离合顶推组件240的结构设置和安装配置。
值得说明的是,为了降低传动连接组件230移动操作对第一传动齿轮212和第二传动齿轮222的干扰,可将环形座2321设置在第二传动齿轮222的远离第一传动齿轮212的一侧,连接臂2311轴向穿过第二传动齿轮222,并可进一步移动卡入卡槽211内,从而顶推环形座2321的操作不会在延伸到两个传动齿轮之间,能够保持二者的相对稳定。
参见图10,在一些实施方式中,顶推套241作为顶推媒介,可在顶推套241上设置轴套部2412和推顶部2411,可将环形座2321套接在轴套部2412上,保持环形座2321可转动的状态;相应地,推顶部2411用于接受推杆242推顶力,使得顶推套241整体沿第一传动齿轮212的转轴轴线方向移动,以实现传动连接组件230的顶推操作。
在一些实施方式中,顶推套241的移动方向为第二传动齿轮222的转轴轴向,为了便于描述将顶推套241移动的方向定为第一方向。为了降低装置的整体厚度,降低成型和装配难度,可采用变向顶推的方式推动顶推套241,也就是说,推杆242的推动方向并不在第一方向,而是存在一定的角度,从而降低在第一方向的空间占用需求。
参见图10、图11和图12,可具体在推顶部2411设置第一顶推面2413,在推杆242上设置第二顶推面2421,第一顶推面2413和第二顶推面2421可接触并可相对滑动,并且将第一顶推面2413相对于第一方向设置成锐角,通过顶推第一顶推面2413实现沿第一方向的顶推顶推套241,进而推动传动连接组件230推向第一传动齿轮222。
在一些实施方式中,为了优化顶推操作的效率,可将第一顶推面2413与第一方向的夹角设置在30度~60度范围内,例如可以是30度、45度或者60度等。
在一些实施方式中,可将推杆242的顶推方向与第一方向的夹角按照90度控制,尽量缩小推杆242与传动连接组件230的配合关系所需要的布置空间,降低装置整体体积规模。
参见图11和图12,在一些实施方式中,为了平衡顶推套241的受力,可将第一顶推面2413的数量设置成两个,相应的推杆242也设置有两个推臂2422,对应顶推两个第一顶推面2413;从而通过两点施力的方式保证顶推套的受力均匀性。并可将两个推臂2422连接在同一个连接部2423上,实现同步动作且保证施力的大小一致,保证顶推套241受力均匀。相应地,两个推臂2422上分别设置有第二顶推面2421。
在一些实施方式中,可将两个第一顶推面2413设置于顶推套241的相背两侧,两个推臂2422并列设置,第二顶推面2421设置在推臂2422上的远离连接部2423的端部,通过顶推连接部2423即可实现顶推操作。
在一些实施方式中,可根据顶推套241的规格情况,将第一顶推面2413、第二顶推面2421以及推臂2422的数量设置成两个以上。
参见图4和图5,为了实施推杆242的顶推操作,可在推杆242上连接直线驱动器243,沿第二方向顶推推杆242或者复位,从而通过直线驱动器推动所述的顶推套241沿第一方向移动。在直线驱动器243复位时,推杆242释放顶推套241。
在一些实施方式中,直线驱动器243可采用电磁推杆,滚珠丝杆等直线驱动组件。
在一些实施方式中,驱动器设置成减速电机,或者配置有减速齿轮箱的电机,从而能够合理控制输出扭矩和转速。
参见图14,在一些实施方式中,为了降低推杆242与底座900以及底座900与顶推套241之间的冲击振动,可在底座900与推杆242之间,以及顶推套241与底座900之间设置减震垫244。
在一些实施方式中,由于顶推套241受到环形座2321的轴向摩擦作用,因此存在一定的周向转动的趋势,为此容易影响与离合顶推组件240的配合。可在底座900上设置防转机构930,沿第一方向卡嵌进顶推套241内,用于止挡顶推套241的周向转动。
参见图10、图14和图15,在一些实施方式中,防转机构930可包括防转筋条931,且防转筋条931可在第一方向上与顶推套241相对滑动,从而可兼顾防止顶推套241周向转动和第一方向滑动的效果。一般来说,可在顶推套241内开设防转卡槽2414,防转卡槽2414与防转筋条931适配,二者沿第一方向相对滑动。
在一些实施方式中,防转筋条931和防转卡槽2414形成的组合结构的数量可以是多个,同时多个防转筋条931的间隔可设置成不等,从而使得顶推套241与防转筋条931的装配位置是唯一的,保证在装配时第一顶推面2413和第二顶推面2421的稳定可靠的对位,避免出现装配错位的情况,实现有效的机械防呆效果。
在一些实施方式中,可在底座900上设置凸起的筒型件,将防转筋条931设置在筒型件的外壁上,并可将顶推套241套接在筒型件外,实现定位和导向。可具体将筒型件与共用转轴920同轴设置。
参见图4、图5和图6,在一些实施方式中,为了在解除连接端231与第一传动组件210的连接状态时,达到即时高效的响应,可设置分离组件250,向传动连接组件230施加脱离第一传动组件210的作用力,在推杆242复位后,留出足够的移动空间,传动连接组件230在分离组件250的作用下实现与第一传动组件210分离。
在一些实施方式中,分离组件250可分别与传动连接组件230和第二传动组件220连接,通过推动顶推端232相对于第二传动组件220移动,促使连接端231与第一传动组件210断开连接。
为了提升响应时效,可将分离组件250设置成一弹性复位件253,持续施加促使传动连接组件230脱离第一传动组件210的作用力。在推杆242推动顶推套241和传动连接组件230与第一传动组件210连接并保持连接状态的过程中,弹性复位件253的作用力仍然存在,但是受限于推杆242、顶推套241和传动连接组件210的机械移动的强力作用,分离作用力被抵消。当推杆242改变推动顶推套241的状态,顶推套241复位后移,顶推套241将逐步降低推顶力,弹性复位件253的作用力将推顶传动连接组件230的连接端231脱离与第一传动组件210的连接,从而具备良好的响应时效。
在一些实施方式中,弹性复位件253可设置成弹簧,弹簧设置在顶推端232和第二传动组件220之间,持续施加使传动连接组件230脱离第一传动组件210的弹性作用力。
在一些实施方式中,分离组件250可以分别与第二传动组件220和底座900相连,以引导传动连接组件230相对于底座900移动,从而使得传动连接组件230的连接端231脱离与第一传动组件210的连接关系。
在一些实施方式中,可将分离组件250设置成两个具备磁性作用力的第一分离件251和第二分离件252,利用二者的磁吸附和磁排斥作用力使得传动连接组件230相对于底座900移动,断开传动连接组件230与第一传动组件210的连接状态。
第一分离件251和第二分离件252中的一个设置在底座900,另外一个设置在传动连接组件230上,第一分离件251和第二分离件252具备相互磁吸附作用力,使底座900和传动连接组件230保持相互靠近的趋势,以提供持续将传动连接组件230与第一传动组件210分离的作用力。
在图4所体现的布置状态下,即第一传动组件210、第二传动组件220、传动连接组件230和底座900顺次叠放布置状态下,第一分离件251和第二分离件252分别连接在传动连接组件230和底座900上,保持二者持续磁拉力,将所述传动连接组件230拉向底座900。
在另外一些实施方式中,还可以是第一分离件251和第二分离件252中的一个设置在传动连接组件230上,另外一个设置在第一传动组件210或第二传动组件220,第一分离件251和第二分离件252具备相互磁排斥作用力,保持的磁斥力,保持传动连接组件230与第一传动组件210或第二传动组件220相互远离的趋势,以提供持续将传动连接组件230与第一传动组件210分离的作用力。
在图4所体现的布置状态下,第一传动组件210、第二传动组件220、传动连接组件230和底座900顺次叠放布置状态下,第一分离件251和第二分离件252其中一个设置在传动连接组件230上,另外一个设置在第一传动组件210或第二传动组件220或者更外侧的上盖上,保持二者持续磁斥力,将所述传动连接组件230推向底座900。
在一些实施方式中,可将第一分离件251和第二分离件252设置成磁吸金属件和磁体,从而形成持续的分离作用力。
参见图4、图5、图6和图14,在一些实施方式中,可通过止挡组件260将第一传动齿轮212 和第二传动齿轮222止挡在共用转轴920上,并限制二者轴向脱离,保证传动结构的稳定性和可靠性。
止挡组件260可以设置成连接件261和止挡件263,连接件261的一端连接在底座900或者其表面结构上,如连接在共用转轴920,并将第一传动组件210和第二传动组件220设置在连接件261上,而后将止挡件263固定在连接件261的另一端,以挡设第一传动组件210和第二传动组件220,避免第一传动组件210或第二传动组件220脱离连接件261,保证离合传动结构的稳定。
在一些实施方式中,连接件261和止挡件263可以集成设置成带头螺栓,以螺栓头作为止挡件263,或者设置独立的止挡件263套接在螺杆上,以螺栓头限制止挡件263脱离。
在一些实施方式中,可在共用转轴920的顶端,沿共用转轴920的轴线方向设置紧定通孔923,用于配合带头螺栓将第一传动组件210和第二传动组件220锁定。
在一些实施方式中,可将带头螺栓的杆体部分设置成光滑周面,而后将紧定通孔923的内壁面设置成光源内周面,实现两者的低摩擦匹配,避免影响第一传动组件210和第二传动组件220的传动操作。可在紧定通孔的另一端口设置锁定件262,将带头螺栓锁定。锁定件262可选用插销或者螺母。
在一些实施方式中,可将连接件261设置成连接轴2611,连接轴2611一端固定于底座900上,第一传动组件210、第二传动组件220和顶推套241套设于连接轴2611上限制沿连接轴2611的径向的脱离;止挡件263可以设置成挡板2631,挡板2631固设于连接轴2611的另一端,从而实现沿连接轴2611的轴向限位,止挡第一传动组件210、第二传动组件220和顶推套241沿轴向脱离。
在一些实施方式中,挡板2631可一体成型在连接轴2611上。
在一些实施方式中,挡板2631可拆卸地固定在连接轴2611上,如通过开设在挡板2631上的卡孔或者卡槽,卡嵌在连接轴2611端头部的一个细颈凹槽内,或者相类似卡嵌方式。
在一些实施方式中,挡板2631还可以通过连接在连接轴2611端头部的锁定件固定在连接轴2611上,如插销等。
在执行离合控制时,通过直线驱动器243动作,推动推杆242朝向顶推套241移动,推杆242头端的第二顶推面2421顶推第一顶推面2413,实现顶推套241沿第一方向移动,推顶连接端231向第一传动齿轮212移动,直至连接端231嵌入卡槽211内,使得第一传动齿轮212和第二传动齿轮222连接为一体。此时,直线驱动器243停留在当前位置,通过推杆242于底部900支撑顶推套241,进而支撑传动连接组件230,使第一传动组件210和第二传动组件220保持传动连接状态。当需要断开连接时,直线驱动器243复位,传动连接组件230的连接端231在分离组件250的作用下逐步脱离卡槽211,直至断开第一传动齿轮212与第二传动齿轮222的连接,中断动力传递路径。
参见图1,在一些实施方式中,驱动机构100可包括驱动器110和输出齿轮120,输出齿轮120固设在驱动器110的输出转轴上,从而可在驱动器110的驱动下绕其转轴轴线转动,输出扭矩。
输出齿轮120与第一传动组件210啮合,从而驱动第一传动组件210转动。输出齿轮120可以与第一传动组件210并排啮合布置。并可进一步将驱动机构100,转门机构400布设在第一传动组件210和联动齿轮300的转动中心438的连线的同侧,能够在一定程度上提升布置紧凑性。
参见图15和图18,在一些实施方式中,顶门机构500可包括顶门件520,且顶门件520可移动地设置在底座900上,联动齿轮300上的限位槽320内开设有顶门面322;在驱动机构100驱动联动齿轮300转动的条件下,顶门面322能够随着联动齿轮300转动,推动顶门件520相对于底座900移动,以使顶门件顶开门体13。
在一些实施方式中,在门体13关闭的情况下,顶门件520一端位于限位槽320内,在联动齿轮300转动的情况下,联动齿轮300通过顶门面322推动顶门件520相对于底座900移动以推动门体13,再带动转门机构400继续转动门体13。
在本公开一个或多个实施方式中,由于门体13关闭在箱体12上时为了提高二者之间的密封效果,通常会以较大的压力将门体13压合在箱体12上,或者是通过吸附结构将门体13吸附在箱体12上,导致门体13和箱体12之间具有较大的吸附力。在打开门体13时需要以较大的作用力才能使门体13和箱体12之间脱离吸附。在联动齿轮300转动的条件下,顶门面322能够推动顶门件520相对于箱体12移动,以较大的力将门体13顶开,通过设置在联动齿轮300上的顶门面322直接和顶门件520作用,能够直接顶开门体13,即可通过一个驱动机构100驱动联动齿轮300转动,使顶门件520顶开门体13,转门机构400在将门体13打开至一个加大的开度,能够减少整个开关门装置的零部件数量,提高整个开关门装置的集成度并且具备稳定的顶推施力方向和效果。
在一些实施方式中,在联动齿轮300转动的条件下,顶门件520不能跟随联动齿轮300转动,顶门件520能够在顶门面322的作用下向靠近或远离门体13的方向上移动,从而顶开门体13。顶门件520可与顶门面322的外表面贴合,在联动齿轮300转动的过程中,顶门件520在顶门面322的外表面的形状移动,在靠近或远离门体13的方向上移动,以顶开门体13。
也就是说,在本公开一个或多个实施方式中,顶门件520和顶门面322之间可以没有直接的连接关系,顶门件可能与顶门面322接触,也可能与顶门面322不接触,在驱动结构驱动联动齿轮300 转动时,顶门件可与顶门面322抵持,并通过顶门面322推动顶门件向靠近门体13的方向移动,以顶开门体13。
换言之,在本公开一个或多个实施方式中,顶门面322跟随联动齿轮300转动,而顶门件520做直线运动,具备稳定的顶推施力方向和效果。
为了方便描述,定义联动齿轮300能够使门体13打开的转动方向为正转,若开关门装置接收到开门信号,则驱动结构带动联动齿轮300正转,转门机构400能够跟随联动齿轮300正转,从而打开门体13。若开关门装置接收到关门信号,则驱动结构带动联动齿轮300反转,转门机构400能够跟随联动齿轮300反转,从而关闭门体13。
参见图15、图18、图22、图23和图24,在一些实施方式中,在顶门面322跟随联动齿轮300转动的条件下,顶门面322与顶门件520抵持,能够推动顶门件520相对于底座900移动,以使顶门件520顶开门体13。
顶门面322可设置在限位槽320的一侧,与所述过渡面328相对,在顶门面322跟随联动齿轮300转动的过程中,顶门面322与顶门件520抵持,使顶门件520向靠近门体13的方向运动,顶门件520逐渐伸出至门体13外,随着联动齿轮300的转动,顶门件520伸出至箱体12外的部分越来越多,从而逐渐顶开门体13。
在一些实施方式中,顶门面322凸设在联动齿轮300上,则顶门面322上各处具有联动齿轮300的中心的距离不同,由于顶门面322上各处到联动齿轮300的转动中心438的距离不同,在联动齿轮300转动的过程中,顶门面322对抵持顶门件520向靠近门体13的方向移动,使顶门件逐渐顶开门体13。
在一些实施方式中,顶门面322逐渐向远离联动齿轮300的转动中心438的方向延伸;可以理解为顶门面322是倾斜设置的,在门体13关闭在箱体12上时,顶门件520设置在限位槽320的内,位于顶门面322与联动齿轮300的周面的衔接部,最接近联动齿轮300的转动中心438的位置,由于顶门面322向远离联动齿轮300的转动中心438的方向凸设且倾斜设置,在联动齿轮300在驱动结构的驱动下转动时,顶门面322会抵持顶门件520向靠近门体13的方向运动,使顶门件520逐渐伸出至箱体12外,从而顶开门体13。
容易理解的是,顶门件520顶开门体13的角度和顶门面322和联动齿轮300的转动中心438的距离相关,为了方便描述定义顶门面322上具有联动齿轮300的转动中心438最远的点为连接点326。若连接点326与联动齿轮300的转动中心438的距离越远,则顶门件520伸出的长度越长,门体13打开的角度就越大。
在一些实施方式中,顶门件520能够顶开门体13的角度为3度到5度,具体角度以突破门体13开门阻力所需要的角度灵活设置。
在一些实施方式中,在顶门面322顶抵门体13的过程中,可能是在顶门面322的中间位置已经顶开门体13,在继续转动的过程中,使门体13能够打开一个较小的角度,方便转门机构400继续打开门体13。
参见图18和图24,在一些实施方式中,联动齿轮300的周面上还包括避让面324,避让面324与顶门面322连接,在顶门件与顶门面322脱离抵持后,顶门件520能够跟随避让面324复位。
在联动齿轮300正转的方向上,顶门面322设置在避让面324的前方,也就是说,在联动齿轮300转动的过程中,先是顶门面322和顶门件520接触,顶抵顶门件520向靠近门体13的方向运动,在顶门件520与顶门面322脱离抵持后,顶门件520和避让面324接触,使顶门件520能够向远离门体13的方向运动,在顶门件520顶开门体13后,能够收回至箱体12上,方便后续关门。
容易理解的是,若联动齿轮300上未设置避让面324,在顶门件520顶开门体13后,顶门件520始终伸出至门体13外,在需要关闭门体13时,顶门件520位于箱体12外,会与门体13发生干涉,导致门体13无法关上,因此,设置避让面324的主要目的在于能够使顶门件520在顶开门体13之后,给顶门件520提供可以回收至箱体12上的空间,使顶门件520在顶开门体13之后,能够收回至箱体12上,避免门体13无法收回。
在顶门面322将顶门件520顶抵至箱体12外后,在避让面324转动至顶门件520的后方时,顶门件520无法自动回位,无法自动跟随避让面324回收至箱体12上,可以在底座900和顶门件520上设置弹性件510,通过弹性件510的回复力,将顶门件520回收至箱体12上。
参见图18和图23,即在顶门面322在顶抵顶门件520的过程中,弹性件510逐渐产生形变,在连接点326和顶门件520接触时,弹性件510形变达到最大,在驱动结构驱动联动齿轮300继续转动的过程中,顶门件520与顶门面322脱离抵持,脱离抵持后,避让面324给顶门件520提供了可回收至箱体12上的空间,在弹性件510的回复力作用下,顶门件520向远离门体13的方向运动,使整个顶门件520都能够回收至箱体12上,方便门体13的关闭。
在一些实施方式中,弹性件510可以是弹簧,也可以是扭簧,任选一种即可。
在弹性件510为弹簧的条件下,弹簧的一端与顶门件连接,另一端可固定在底座900上,可以固定在联动齿轮300的连接轴2611上,其中,转轴是与底座900固定连接的。也就是说,弹簧远离顶门件的一段需要与固定结构连接即可。
若弹性件510为弹簧,在顶门面322在顶抵顶门件520的过程中,弹簧逐渐被拉伸,在连接点326和顶门件520接触时,弹簧的拉伸量达到最大,在驱动结构驱动联动齿轮300继续转动的过程中,顶门件520与顶门面322脱离抵持,脱离抵持后,避让面324给顶门件520提供了可回收至箱体12上的空间,在弹簧的回复力作用下,顶门件520向远离门体13的方向运动,使整个顶门件520都能够回收至箱体12上,方便门体13的关闭。
当弹簧为扭簧的条件下,扭簧的中部和扭簧的第一端设置于底座900上,扭簧的第二端与顶门件520连接,其中,中部分别与第一端及第二端连接,在顶门件520顶开门体13时,顶门件需要克服扭簧的扭力。
若弹性件510为扭簧,在顶门面322顶抵顶门件向靠近门体13的方向运动的条件下,扭簧被扭转,当顶门件520和顶门面322脱离抵持后,在扭簧的回复力的作用下,顶门件520能够跟随避让面324向远离门体13的方向运动,使顶门件520能够复位,以避免顶门件520与门体13干涉,从而方便关门。
在一些实施方式中,顶门面322与避让面324连接于连接点326,连接点326与联动齿轮300的转动中心438的距离大于避让面324及顶面面上任意一点到联动齿轮300的转动中心438的距离。
在一些实施方式中,顶门面322与避让面324之间相互连接,可定义二者之间相互连接的点为连接点326,连接点326为顶门面322和避让面324上距离联动齿轮300的转动中心438最远的点,在连接点326和顶门件520顶抵的条件下,顶门件520将门体13顶开的角度最远,在避让面324转动顶门件520处后,避让面324给顶门件520提供了向远离门体13方向运动的空间,使顶门件520能够收回至箱体12上,方便后续关门。
容易理解的是,顶门面322在顶抵顶门件520顶门的过程中,门体13逐渐打开,并非在连接点326和顶门件接触时,顶门件520才打开门体13,在顶门面322跟随联动齿轮300转动的过程中,可能是顶门面322上的其中一个点在与顶门件顶抵时,顶门件520顶开了门体13,只是在连接点326和顶门件520顶抵时,顶门阶段的门体13的开度到最大角度。
至于顶门件520顶门的速度,与驱动结构驱动联动齿轮300的转动速度相关,联动齿轮300转动的速度越快,则顶门件520顶开门体13的速度越快。若联动齿轮300转动的速度越慢,则顶门件520顶开门体13的速度就越慢。
在一些实施方式中,避让面324和顶门面322可以是弧面,也可以是倾斜设置的平面。
需要说明的是,在一些实施方式中,转门机构400的一端与联动齿轮300连接,另一端和门体13连接,可通过同一个驱动结构和联动齿轮300驱动顶门件520和转门机构400以实现顶门和开门的功能;具体由顶门件520先将门体13顶开一个较小的角度,转门机构400再将门体13进一步地打开。
参见图15,在一些实施方式中,底座900上设置有安装槽912,顶门件520活动设置在安装槽912内。安装槽912呈长条状,顶门件520设置在安装槽912内,能够沿着安装槽912的延伸方向移动,使顶门件520能够向靠近或远离门体13的方向运动。
安装槽912的延伸方向可由联动齿轮300沿着至门体13,为了能够减少顶门件520在顶门时,顶门力的损失,在门体13关门时,安装槽912可与门体13垂直。
在一些实施方式中,顶门面322和联动齿轮300一体成型。二者一体成型,相当于联动齿轮300直接和顶门件520作用,能够减少其他零部件的设置,减少开关门装置11的结构,以降低占用空间。
联动齿轮300在驱动结构的带动下转动,通过顶门面322的设置,能够将转动转化为顶门件520的移动,通过联动齿轮300可实现在开门前的顶门,提高了联动齿轮300的应用范围,减少了顶门件520的驱动结构,从而减少了开关门装置11的结构,降低了占用空间。
综上所述,依据本公开实施方式的开关门装置11,由于门体13关闭在箱体12上时为了提高二者之间的密封效果,通常会以较大的压力将门体13压合在箱体12上,或者是通过吸附结构将门体13吸附在箱体12上,门体13和箱体12之间具有较大的吸附力,在打开门体13时需要以较大的作用力使门体13和箱体12之间脱离吸附。在联动齿轮300上设置顶门面322,在联动齿轮300转动的条件下,顶门面322能够推动顶门件将对于箱体12移动,从而将门体13顶开,通过设置在联动齿轮300上的顶门面322直接和顶门件520作用,能够直接顶开门体13,即通过一个驱动结构可驱动联动齿轮300转动,从而使顶门件520顶开门体13,能够减少整个开关门装置11的零部件数量,提高整个开关门装置的集成度。
参见图16、图25、图26和图27,在一些实施方式中,顶门机构500还可设置成凸设于联动齿轮300上的顶门部350,在联动齿轮300转动的情况下,顶门部350伸出至底座900外,以直接突破 门体13的吸附力等开门阻力顶开门体13,便于转门机构400转动门体13,从而一定程度上降低开门难度。
值得说明的是,顶门部350顶开门体13,是指在门体13关闭主体12,即门体13吸附在主体12上的条件下,顶门部350根据联动齿轮300转动,在顶门部350转动的过程中,顶门部350逐渐与门体13作用,使门体13和主体12脱离吸附,从而顶开门体13。
在一些实施方式中,顶门部350具有顶门点351,在驱动机构带动联动齿轮300转动的条件下,顶门点351与门体13抵持,以顶开门体13。
在驱动器件带动联动齿轮300转动的过程中,顶门部350逐渐与门体13接触,在驱动机构继续驱动联动齿轮300转动的条件下,顶门部350伸出至主体12外,使顶门点351顶开门体13。
在一些实施方式中,顶门点351为顶门部350上距离联动齿轮300的转动中心438最远的一点,在驱动机构驱动联动齿轮300转动的过程中,顶门部350跟随联动齿轮300转动,顶门点351能够将门体13顶至顶门部350能够将门体13顶抵的最远处。
在一些实施方式中,顶门部350具有外观面352,顶门点351设置在外观面352的一端。
外观面352可以为平面,顶面点设置在外观面352的一端,在驱动器件驱动联动齿轮300转动的过程中,外观面352的一部分转动至主体12上,另一部分转动至主体12外,在主体12外的部分逐渐与门体13顶抵,直至顶门点351与门体13抵持,将门体13顶开。
容易理解的是,在外观面352跟随联动齿轮300转动的过程中,外观面352伸出至主体12外的部分逐渐与门体13抵持,在转动的过程中,外观面352伸出的部分越来越多,增大与门体13抵持力,使门体13能够克服与主体12之间的吸附力,从而顶开门体13。
在门体13关闭时,外观面352与主体12的开口齐平,在驱动机构驱动联动齿轮300转动的过程中使顶门点351能够快速地转动至主体12外,使顶门点351能够快速地顶开门体13。
在另外一些实施方式中,在门体13关闭的条件下,外观面352与主体12的开口齐平能够保证开关门装置11未启动时,外观的美观性。
当门体13转动到预设的开度位置时,联动齿轮300将不再驱动转门机构400动作,并停止向联动齿轮300施加驱动力以维持其转动位置,从而中断门体13与上游驱动器件的驱动关系,避免与人工操作门体13相干涉,方便人工操作门体13。但由于冰箱等电器设备门体13上储物,或者冰箱放置偏斜等因素造成门体重心偏移,导致门体13自主偏转,从而无法维持门体13的开度,不便于使用,甚至会造成碰撞操作人员的安全风险。
参见图1、图2、图22、图23和图24,在一些实施方式中,为了解决开关门装置停机时门体13无法维持开度的问题,可在联动齿轮300上开设限位槽320,并在底座900上设置悬停机构600,在联动齿轮300转动到某一位置使得限位槽320与悬停机构600处于相对的状态时,悬停机构600相对底座900移动而后顶抵在限位槽320上,将联动齿轮300锁定在底座900上,以制动转门机构400转动门体13,实现门体13的悬停,保持在预设开度位置。
即,可复用悬停机构的限位槽320,实现悬停制动限位,还能够利用其形态特点作为顶推顶门件520的功能部,简化联动齿轮300的结构。当然也可设置独立的限位槽320,本公开实施方式不做限制。
也就是说,限位槽320跟随联动齿轮300转动,悬停机构600可相对于底座900移动,并能够响应联动齿轮300的转动位置变化而改变其移动的状态,从而当限位槽320转到与悬停机构600匹配相对的位置时,悬停机构600可顶抵卡紧限位槽320,从而锁止联动齿轮300,限制其转动,从而制动转门机构400,以阻挡门体13偏转,从而保持门体13悬停在预设位置。
值得说明的是,悬停机构600和限位槽320的顶抵锁止状态为可逆的状态,当联动齿轮300受到的外部驱动力的作用大于悬停机构600与限位槽320之间的制动力时,联动齿轮300突破顶抵限位作用,继续转动,联动齿轮300解除制动状态,可驱动转门机构400转动门体13至关闭,或者也可进一步扩大门体13的开度。
参见图17、图18、图19、图20和图21,在一些实施方式中,悬停机构600可包括悬停件610和顶推件620;悬停件610可移动地设置底座900上,持续顶抵在联动齿轮300上,并且能够匹配顶抵卡紧限位槽320。在联动齿轮300使得限位槽320与悬停件610相对的状态时,悬停件610可向联动齿轮300移动并顶抵在限位槽320上,将联动齿轮300锁定在底座900上,实现联动齿轮300的制动;顶推件620作为悬停件610的驱动元件,持续向悬停件提供推顶力,将悬停件610向联动齿轮300向联动齿轮300推顶,从而可推顶悬停件610与限位槽320的实现联动齿轮300的顶抵制动。
需要说明的是,悬停件610在持续推顶力的作用下,始终保持与联动齿轮300的顶抵状态,在联动齿轮300转动过程中,悬停件610在联动齿轮300上滑动;仅在联动齿轮300转动到使限位槽320与悬停机构600相对的状态的情况下,在推顶力的作用下悬停件610移动并顶抵于限位槽320内,制动联动齿轮300。通过持续的推顶力使得悬停件610能够跟踪联动齿轮300的转动位置,高时效响应限位 槽320的到位状态,即限位槽320与悬停机构600对位后,悬停件610即刻顶抵卡紧限位槽320。在悬停件610上可设置顶抵部611,用于接触顶抵限位槽320,并可具体通过顶抵进限位槽320的内部,实现接触顶抵制动。
参见图18,在一些实施方式中,限位槽320可设置成位于联动齿轮300周面上的凹槽,相配合的,悬停件610的顶抵部611可设置成与凹槽的槽型匹配的凸部,且保证顶抵部611可卡嵌进入和脱离凹槽,以便于顶抵部611顺利卡紧制动和脱离解除制动。
值得说明的是,凹槽的槽口可设置用于平滑衔接联动齿轮300的周面的衔接面,便于顶抵部611相对于联动齿轮300的周面顺畅滑动进入凹槽和自凹槽顺畅脱离,从而在实施制动和解除制动时,均能够舒畅稳定达成。
在一些实施方式中,凹槽的槽型可设置成C型或者V型,相应地,顶抵部611也设置成可嵌入的圆弧形或者尖塔形结构。
为了便于顶抵部611顺利脱离凹槽,顶抵部611可与凹槽之间留有一定的间隙,当顶抵部611卡嵌入凹槽内时,顶抵部611的部分区域顶抵在凹槽内壁上,另一部分区域与槽壁之间形成间隙,在保证卡紧的前提下,也便于受到略大于推顶力时,顶抵部611可顺利从凹槽中脱离。
参见图17和图21,在一些实施方式中,考虑到推顶力及其作用效果的稳定性对顶抵部611的制动性能有着积极效果,可在悬停件610上开设推顶限位槽612,将顶推件620设置在推顶限位槽612内从而使得顶推件620和悬停件610之间保持相对稳定的连接状态,一定程度上能够降低两者相对摆动的幅度,从而保持顶抵部611的受力方向、移动方向以及顶抵部611与限位槽320的接触区域的稳定,保证制动效果。顶推件620也可与顶推部611直接连接,将推顶力的作用点集中在推顶部611上,从而降低由于悬停件610自身的姿态变化导致的顶推力的方向偏移和顶抵效果不稳定的风险。
值得说明的是,推顶限位槽612与顶推件620的大小规格可进行匹配设计,使得推顶限位槽612的规格可略大于顶推件620的宽度,缩小相对摆动的空间,保持推顶力的方向的稳定。
在一些实施方式中,可将推顶限位槽612设置成沿推顶力方向且可容纳顶推件620的盲孔,孔底设置在推顶部611上,形成对顶推件620的周向限位,从而能够限制周向摆动幅度,降低悬停件610受力弹起的风险,保证顶推位置和姿态的稳定。
在一些实施方式中,悬停件610的一端设置顶抵部611,用于接触顶抵限位槽320,悬停件610的另一端还可设置连接部,用于连接顶推件620,从而便于悬停件的成型加工,简化工艺流程。
在一些实施方式中,顶推件610可以为弹性件,从而通过弹性件的弹性形变施加持续且连续的推顶力,保证悬停件610以简洁的结构高时效响应联动齿轮300的转动位置变化,能够在限位槽320到位时,迅速顶抵入限位槽320内;同时,弹性件的弹性形变的稳定性使得其施加到悬停件610上的顶推力也能够保持稳定状态,一方面能够保持悬停状态的稳定,另一方面,还能够使联动齿轮300在一个相对稳定且可控的驱动力的作用下转动并解除制动状态,从而实现开关门装置的悬停功能的稳定性、可靠性以及可平滑顺畅地实现的性能。
鉴于弹性件的形变可分为压缩形变和拉伸形变,弹性件应当以相对稳定且线性的形变状态为原则设置装配方式。
在弹性件为压缩态提供弹性的推顶力时,可将悬停件610设置在弹性件和联动齿轮300的周面之间,将弹性件压缩布置在底座900和悬停件610之间,并保持形变复位方向与推顶力方向一致,从而将弹性件的弹性推力转化为稳定的弹性推顶力输出。
在弹性件为拉伸态提供弹性的推顶力时,可将弹性件拉伸设置在底座900和悬停件610之间,并保持形变复位方向与推顶力方向一致,从而将弹性件的弹性拉力转化为稳定的弹性推顶力输出。
在一些实施方式中,弹性件可以为弹簧,并可具体设置成压簧或者拉簧,从而通过压缩形变或者拉伸形变提供稳定的推顶力。具体可将压簧压缩在悬停件和底座之间,或者可将拉簧拉伸连接在悬停件和底座之间。
参见图20和图21,可具体将压簧的第一端顶抵在推顶部611上,在底座900上设置与弹簧大致等高的凸台部909,并将弹簧的第二端顶抵在凸台部909上,保持压簧在其轴向上的平直姿态,以形成稳定可靠的推顶力。
在一些实施方式中,可以将拉簧的第一端固定在顶推件610的主体上,或者直接固定在推顶部611上,并将拉簧的第二端固定在底座900上设置的凸台部909上,并尽量拉簧与底座900的板面持平并保持平直姿态,以形成稳定可靠的推顶力。
在一些实施方式中,还可在凸台部909的下方设置支撑槽908用于限位支撑上述弹簧,从而保证其顶抵位置的稳定,避免晃动。
在一些实施方式中,也可采用如扭簧,簧片等类型的弹性件,满足弹力方向与悬停件610的移动方向大致吻合即可,此处不再赘述。
在一些实施方式中,为了维持悬停件610的移动方向的稳定,限制过度摆动和震动,可在底座 900上设置悬停限位滑槽906,并将悬停件设置在悬停限位滑槽906内,通过滑槽侧壁的导向和约束作用,保持悬停件610的移动方向的稳定,进而保证制动性能的可靠性。
参见图20,在一些实施方式中,悬停限位滑槽906可设置成两个相对的限位凸台907,且限位凸台907在悬停件610移动方向上具备一定的长度,满足滑动行程内的限位即可。还可以在两个限位凸台907的顶部连接上限位结构,一定程度上可以限制其脱离底座;还可在底座900的上盖上设置相应的上限位结构,与悬停限位滑槽906相对,从而实现上限位的目的,使得悬停件610能够始终以稳定的方向移动,保证制动性能的可靠性。
在一些实施方式中,为了保持悬停件610的移动方向的稳定,限制不稳定摆动,可将悬停件610设置成杆状,顶抵部611设置在其靠近联动齿轮300的一端;即具备一定长度的长条形结构件,配合悬停限位滑槽906实现稳定滑动,利用其长度特征和悬停限位滑槽906的对长条形结构件径向限位效果,一定程度上降低摆动幅度。悬停限位滑槽906和杆状的悬停件610在推顶力方向上的长度越长,限制摆动幅度的性能越好,悬停件610的移动方向越稳定。
值得说明的是,在门体13关闭的情况下,顶门件520一端位于限位槽320内,悬停机构600抵持于联动齿轮300的周面上;在联动齿轮300转动的情况下,联动齿轮300通过顶门面322推动顶门件520相对于底座900移动以推动门体13,再带动转门机构400继续转动门体13,悬停机构600一端沿联动齿轮300周面滑动以在悬停机构600滑动至限位槽320内时,悬停机构600抵持于限位槽320内,以提供制动联动齿轮300转动的作用力。
参见图28、图29、图30和图33,在一些实施方式中,为了解决开关门装置停机时门体13无法维持开度的问题,可在联动齿轮300上设置悬停结构630,并在底座900上设置限位机构640,在联动齿轮300转动的情况下,限位机构630跟随转动,从而在联动齿轮300转动到预设的开门位置时,悬停结构630可与限位机构640卡合,将联动齿轮300锁定在底座900上,以制动转门机构400转动门体13,实现门体13悬停,将门体13维持在当前位置。
在一些实施方式中,限位机构630上可设置一连接部631和悬停部632,悬停部632通过连接部631与联动齿轮300连接,从而悬停部632可跟随联动齿轮300转动。
悬停部632作为与限位机构640卡合的功能部,其形态可与限位机构640相匹配,从而在悬停部632与限位机构640对位的情况下能够顺利地卡合,并形成一定程度的脱离阻力,即联动齿轮300的制动力,从而将联动齿轮300锁定在底座900上。
值得说明的是,悬停部632与限位机构640的卡合状态为可逆状态,当联动齿轮300受到的外部驱动力的作用大于悬停部632与限位机构640之间的制动力时,联动齿轮300将外部驱动力传递给连接部631迫使悬停部632脱离限位机构640,联动齿轮300继续转动,联动齿轮300解除制动状态,可驱动转门机构400转动门体13关闭,或者也可进一步扩大门体13开度。
参见图29、图30、图31、图32和图33,在一些实施方式中,限位机构640可设置成位于底座900上的限位部642,用于接触限位悬停部632,形成一定的移动阻力,以制动联动齿轮300。并且,可具体在限位部642上开设卡持槽643,从而在悬停部632转动到卡持槽643处时,能够自然卡合于卡持槽643内,从而通过卡持槽643容纳或者部分容纳悬停部632限制其脱离,形成制动力。
在一些实施方式中,为了形成稳定的针对联动齿轮300的制动力,可将悬停部632设置成独立的卡嵌件,且卡嵌件的形态设置成与卡持槽643的槽型匹配的形态,从而在卡嵌件转动到卡持槽643的位置处时,能够形成较大的卡合接触面,一定程度上提升脱离的摩擦阻力,从而形成相对稳定的制动力,便于良好匹配联动齿轮300的驱动力,形成流畅且稳定地联动齿轮300的驱动和制动控制模式,保证开关门装置的运行稳定性和可靠性。
在一些实施方式中,可将卡嵌件设置成可弹性形变件,从而在卡嵌件卡合在卡持槽643的槽体形成一定的弹性接触压力,提升制动力,特别是在脱离卡持槽643时,需要进一步形变才能够脱离槽口,从而形成稳定且可靠的制动力。
值得说明的是,由于卡嵌件跟随联动齿轮300转动,其移动轨迹为弧形,可将卡持槽643设置在卡嵌件的弧形轨迹上,并且偏向联动齿轮300的圆心的一侧,从而在卡嵌件转动到卡持槽643的位置时,需要产生一定的形变才能够卡嵌进卡持槽643内,相应地也需要产生一定的形变才能够脱离卡持槽643,便于形成稳定的制动力。
在一些实施方式中,可将卡嵌件设置成空心筒形件,卡持槽643的槽型也可设置成与空心筒型件的筒型周面适配的结构,从而空心筒形件形变方向主要是孔形筒型件的径向,并且形变区域为空心筒型件在长度方向的周面区域,从而可实现区域化的稳定形变,保证稳定的制动力。
在一些实施方式中,空心筒型件可采用橡胶件,或者具备稳定弹性形变性能的其他材料件。具体的弹性系数可匹配卡持槽643和悬停件610的布置位置,综合设置,保证平滑的卡合和解除卡合操作,降低振动摆幅。
在一些实施方式中,卡嵌件可与连接部631一体成型,从而便于零部件的加工,提升装配效率。 连接部631可通过固定连接机构固定在联动齿轮300上,也可一体成型在联动齿轮300上。
在另一些实施方式中,卡嵌件也可与连接部631通过固定连接结构连接在一起,可便捷拆装更换。相应地,连接部631可与联动齿轮300一体成型,便于整体装配;也可通过固定连接结构固定在联动齿轮300上;从而丰富连接方式,便于维护更换。
在一些实施方式中,为了实现平滑的悬停操作,可在限位部642一侧设置相连接的导向部641,在联动齿轮转动过程中时,悬停部可接触并沿导向部641移动,通过导引部641能够实现缓冲和导向,以引导悬停部平滑卡合于限位槽内,避免悬停部由于惯性作用,无法稳定卡合落位到限位槽内。
在一些实施方式中,导向部641可设置成与联动齿轮300的周面相切的导向平面,卡持槽643设置于导向平面的一端,从而悬停部632在接触并沿着导向平面移动并直接落位卡嵌到卡持槽643内。
值得说明的是,导向平面与悬停部632的弧形轨迹上的相切点可以设置在限位槽的槽口,在悬停部632刚接触导向平面时,形成一定的接触压力后即刻卡合于限位槽内;在联动齿轮300解除制动状态时,需要突破这一接触压力,形成稳定的顶推力,便于联动齿轮300的驱动器件相配实现稳定的驱动控制操作。
在一些实施方式中,还可将连接部631也设置为可弹性变形的弹性连接臂,从而通过弹性连接臂的弹性形变使得悬停部632可平滑稳定的卡合于限位槽内,并在一个稳定的压迫力的作用下,即可脱离限位槽,实现平滑顺畅的制动和解除制动操作。
为了保证悬停结构630的可靠性,弹性连接臂的长度不宜过大,避免过度形变,影响悬停部的受力状态,导致无法稳定卡合于限位槽内,或者容易脱离限位槽,劣化制动效果。
在一些实施方式中,还可在弹性连接臂与联动齿轮300之间设置加强筋板633,以强化连接关系,并一定程度上限制弹性连接臂的过度形变。
在一些实施方式中,可将连接部631采用复合材料成型的方式,将连接部631设置成硬度和弹性渐变的结构,从而兼顾稳定的弹性形变和可靠的结构强度和形态稳定性,保证悬停部632的受力稳定和制动效果。
本公开实施方式提供的开关门装置,通过可由驱动机构100驱动的联动齿轮300带动转门机构400转动门体13,实现自动开关门;并具体通过联动齿轮300正反转,带动转门机构400动作推拉门体13,实现开关门;通过在联动齿轮300上设置限位槽320与设置在底座900上的悬停机构600匹配形成悬停功能结构,作为联动齿轮300制动的功能结构,悬停机构600跟踪联动齿轮300的转动位置,在联动齿轮300转动到预设悬停工位的状态的情况下,通过悬停机构600抵持于限位槽320内,将联动齿轮300锁定在底座900上,实现联动齿轮300的制动,以制动与联动齿轮300相连的转门机构400,从而实现门体13悬停,保证门体13开度的稳定,在降低开门难度的同时还方便使用,降低碰撞风险。同时,复用限位槽320并设置顶门面322和顶门机构500,在联动齿轮300转动的过程中,顶推顶门机构500推动门体13,以突破门体13吸附力等开门阻力,便于转门机构400转动门体13,降低开关门难度。
参见图1和图2,在一些实施方式中,转门机构400可包括端部铰接的前连杆410和后连杆420,前连杆410的另一个端于第一连接点432转动连接在门体13上,且前连杆410设置在联动齿轮300的底面与底座900之间,后连杆420可偏转的设置在联动齿轮300的顶面上开设的安装槽360内,且后连杆的另一端与联动齿轮300于联动齿轮300的转动中心438同轴转动地连接在底座900上,即后连杆420可随联动齿轮300转动,在安装槽360的槽壁上相对开设的第一抵持面361和第二抵持面362的推动下推拉前连杆410,以转动门体13,实现开关门操作。
值得说明的是,前连杆410和后连杆420分别设置在联动齿轮300的两侧,利用联动齿轮300转动支撑于底座900上所预留的厚度空间,而不必占用联动齿轮300的上部空间,从而一定程度上降低转门机构400厚度方向上的空间需求;并将后连杆420下沉设置在安装槽360内,从而使得转门机构400和联动齿轮300的整体装配高度并不会过度高出联动齿轮300的高度,甚至会持平,从整体上通过前连杆410和后连杆420的分侧布置以及安装槽360的应用,可整体降低开关门装置11的厚度。
在一些实施方式中,还可将前连杆410和后连杆420均布置在联动齿轮300的下部空间,位于底座上方,安装槽360也设置在联动齿轮的底面上,从而也能够整体降低开关门装置11的整体厚度。
参见图1,在一些实施方式中,可将转门机构400、驱动机构100以及离合顶推组件240设置在离合机构200与联动齿轮300连线的同侧,从而一定程度上提升整体结构的紧凑程度,从而可以相对降低整体的横向布置宽度,从而实现开关门装置11的小型化成型,具备良好的安装兼容性,便于良好安装到冰箱上,降低对冰箱与其所在周边环境的干涉。
在一些实施方式中,门体13和箱体12转动连接于第一连接点432,前连杆410和门体13连接于第二连接点434,后连杆420和前连杆410转动连接于第三连接点436,联动齿轮300具有转动中心438,且第二连接点434和第三连接点436分别位于第一连接点432和转动中心438的连线两侧,从而使得两个连杆的施力点分别位于上述连线两侧,产生受力形变时,两个连杆的形变方向或者趋势将会是在杆体的两个相对的方向,从而避免向同一侧偏移,平衡维持在一个稳定的界面,从而获得稳定的施 力结构形态,避免过度形变,影响开关门装置的整体形态稳定。
在一些实施方式中,输出齿轮120与第一传动齿轮212的第一连线与第二传动齿轮222与联动齿轮300的第二连线的夹角范围可控制在90~120度,从而使得同侧布置的驱动机构100和转门机构400以及离合顶推组件240都有足够的安置空间。
上述转门机构400可设置在第一连线、第二连线以及门体所围成的区域内。
在一些实施方式中,由于前连杆410的整体和部分后连杆420临空转动,并不会直接接触或者连接其他结构,从而可在前连杆410整体扫过的区域不设置对应的底座结构,使前连杆410设置在底座900区域外,一方面,降低底座900的用料,另一方面,也可以使底座900的固定结构能够一定程度上远离电器设备的边部区域中的走线区等功能部,实现良好的安装兼容性和对环境的适应能力。
在一些实施方式中,可将驱动器110固设于底座900上,并将输出齿轮120设置在驱动器110上方,而具备一定的安装高度,使得第一传动齿轮212与输出齿轮120可并排等高设置,相应的,第二传动齿轮222与联动齿轮300等高并排设置,且第二传动齿轮222位于第一传动齿轮212的下方,从而整体上充分利用厚度空间和宽度空间的布置配合,使得整体厚度和宽度均处于相对较低的水平,便于开关门装置小型化成型。
参见图1,在一些实施方式中,为了准确控制联动齿轮300的转动行程,可在联动齿轮300上设置角度采集单元800,用于实施检测联动齿轮300的转动角度,以作为反馈控制的参数,用于现场控制器控制驱动机构100和离合器200的动作。通常可采用角度检测传感器等,直接装配到联动齿轮300上;当然也可以采用其他类型的角度传感器,此处不再穷举。
本公开实施方式还提供一种电器设备,包括门体13、箱体12及上述开关门装置;在离合器200建立联动齿轮300与驱动机构100之间的传动连接状态的情况下,驱动机构100可驱动联动齿轮300转动,以带动顶门机构500顶开门体13,再由转门机构400转动门体13。
一般来说,电器设备可以是洗碗机、单开门冰箱、双开门冰箱等。
另外,各个实施方式之间的技术方案可以相互结合,但是必须是以本领域普通技术人员能够实现为基础,当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在,也不在本公开要求的保护范围之内。
尽管已经示出和描述了本公开的实施方式,本领域的普通技术人员可以理解:在不脱离本公开的原理和宗旨的情况下可以对这些实施方式进行多种变化、修改、替换和变型,本公开的范围由权利要求及其等同物限定方法。
