具体实施方式
下面将结合本公开实施方式中的附图，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。
此外，本公开可以在不同例子中重复参考数字和/或参考字母，这种重复是为了简化和清楚的目的，其本身不指示所讨论的各种实施方式和/或设置之间的关系。此外，本公开提供了各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的应用和/或其他材料的使用。
下面结合附图并参考具体实施方式描述本公开：
图1示出了依据本公开一些实施方式的冰箱中的开关门装置的装配结构示意图。如图1所示，依据本公开一些实施方式提供了一种冰箱10。在冰箱10上设置有开关门装置11，以实现自动开关门功能，并在一定程度上提升了冰箱门体开关的自动化程度，提升了操作的便捷性，也降低了操作难度。开关门装置11安装到冰箱的箱体12上，并与冰箱的门体13连接。开关门装置11通过推拉门体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，提升了操作便捷性。开关门装置11还能够在门体13到达预设开度后维持门体13开度，从而提升了使用舒适性，避免了门体自主关闭造成的碰撞操作人员的安全风险。一般来说，可将开关门装置11的组件直接设置在箱体12上，还可以设置底座900作为开关门装置11中各功能组件的承载基础，从而使开关门装置11整体固定在箱体12上，从而实现整体装配。
开关门装置11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，也可以是冰箱自身触发的。同样的，开关门装置11在接收到关门信号后可自动关闭门体13。在一些实施方式中，关门信号可以是用户触发的，也可以是冰箱自身触发的。
在本公开一些实施方式中，冰箱10可以包括箱体12和门体13，箱体12可以开设有具有敞口的容纳空间，可通过转动地连接在箱体12的门体13封闭或者打开所述敞口，实现关门或者开门。可在箱体12上安装开关门装置11，且开关门装置11与门体13相连，以便自动推拉门体13使门体13相对于箱体12转动，从而实现自动开关门。
图2示出了图1中的开关门装置的悬停工况下的结构示意图。如图1和图2所示，开关门装置11可以包括：转门机构400、驱动器1000和联动轮300。在一些实施方式中，联动轮300转动地设置在箱体12上，并与驱动器1000和转门机构400连接，从而在驱动器1000启动的情况下，联动轮300受驱转动，以驱动转门机构400带动门体13转动，实现开关门操作。在本公开一些实施方式中，通过设置转门机构400和联动轮300，在驱动器1000的驱动下，转动门体13以实现自动开关门，降低了人工操作的开门难度，提升了便捷性和舒适性。
由于门体转动到预设的开门位置时，驱动器1000将不再施加驱动力，给人工操作门体13留出空间，避免与人工操作门体13相干涉，但也会使得门体13在自带的关门自锁引导力的作用下关闭门体13， 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。
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，可设置悬停装置600，用以制动转门机构400，从而在门体13开启状态下，维持开度。悬停装置600可包括设置在联动轮300上的第一卡合部600a以及设置在箱体12或者底座900上的第二卡合部600b，且在联动轮300转动到使第一卡合部600a和第二卡合部600b相对时，第一卡合部600a与第二卡合部600b卡合，从而制动联动轮300，以制动转门机构400转动门体13。
图3示出了图1中的开关门装置的悬停机构的结构示意图；图4示出了图3中的开关门装置的联动轮的结构示意图；图5示出了图3中的开关门装置的悬停件和推顶件的配合示意图。
如图3、图4和图5所示，为了解决开关门装置停机时门体13无法维持开度的问题，第一卡合部600a可包括开设在联动轮300上的限位结构320，第二卡合部600b可包括悬停件610和推顶件620；悬停件610可移动的设置底座900上，并持续顶抵在联动轮300上，并且能够匹配顶抵卡紧限位结构320，从而在联动轮300使得限位结构320与悬停件610相对的状态时，悬停件610可向联动轮300移动并顶抵在限位结构320上，将联动轮300锁定在底座900上，实现联动轮300的制动；推顶件620作为悬停件610的驱动元件，持续向悬停件610提供推顶力，将悬停件610向联动轮300向联动轮300推顶，从而可推顶悬停件610与限位结构320的实现联动轮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，始终保持与联动轮300的顶抵状态，在联动轮300转动过程中，悬停件610在联动轮300上滑动；仅在联动轮300转动到使限位结构320与悬停装置600相对的状态的情况下，在推顶力的作用下悬停件610移动并顶抵于限位结构320内，制动联动轮300。通过持续的推顶力使得悬停件610能够跟踪联动轮300的转动位置，高时效响应限位结构320的到位状态，即限位结构320与悬停装置600对位后，悬停件610即刻顶抵卡紧限位结构320。在悬停件610上可设置顶抵部611，用于接触顶抵限位结构320，并可通过顶抵进限位结构320的内部，实现接触顶抵制动。
在联动轮300转动到某一位置使得限位结构320与悬停件610处于相对的状态时，悬停件610移动而后顶抵在限位结构320上，将联动轮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，保持预设开度位置。
也就是说，限位结构320跟随联动轮300转动，悬停件610可相对于底座900移动，并能够响应联动轮300的转动改变其移动的状态，从而当限位结构320转到与悬停装置600匹配相对的位置时，悬停装置600可顶抵卡紧限位结构320，从而锁止联动轮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，悬停件610和限位结构320的顶抵锁止状态为可逆的状态，当联动轮300受到的外部驱动力的作用大于悬停件610与限位结构320之间的制动力时，联动轮300突破顶抵限位作用，继续转动，联动轮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开度。
如图3和图4所示，在一些实施方式中，限位结构320可设置成位于联动轮300周面上的凹槽320a，相应地，悬停件610的顶抵部611可设置成与凹槽320a的槽型匹配的形态，且保证顶抵部611可卡嵌进入和脱离凹槽320a，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320a的槽口可设置用于平滑衔接联动轮300的周面的衔接面，便于顶抵部611相对于联动轮300的周面顺畅滑动进入凹槽320a和自凹槽320a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320a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320a，顶抵部611可与凹槽320a之间留有一定的间隙，即，当顶抵部611卡嵌入凹槽320a内时，顶抵部611的部分区域顶抵在凹槽320a的内壁上，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可顺利脱离。
图7示出了图3中的开关门装置的悬停件与悬停限位滑槽的配合示意图。如图3和图7所示，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，将推顶件620设置在推顶限位槽612内从而使得推顶件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与限位结构320的接触区域的稳定，保证制动效果。在一些实施方式中，推顶件620也可与顶抵部611直接连接，将推顶力的作用点集中在顶抵部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与推顶件620的大小规格可进行匹配设计，使得推顶限位槽612的规格可略大于推顶件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推顶件620的盲孔，孔底设置在顶抵部611上，形成对推顶件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，用于接触顶抵限位结构320，悬停件610的另一端还可设置连接部，用于连接推顶件620，从而便于悬停件610的成型加工，简化工艺流程。
在一些实施方式中，推顶件620可设置成弹性件620a，从而通过弹性件620a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轮300的转动位置变化，能够在限位结构320到位时，迅速顶抵入限位结构320内；同时，弹性件620a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11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620a的形变可分为压缩形变和拉伸形变，弹性件620a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620a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620a和联动轮300的周面之间，将弹性件620a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620a的弹性推力转化为稳定的弹性推顶力输出。
在弹性件620a为拉伸态提供弹性的推顶力时，可将弹性件620a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620a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620a为弹簧，并可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。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610和底座900之间。
图6示出了图3中的开关门装置的悬停限位滑槽的结构示意图。如图6和图7所示，可将压簧的第一端顶抵在顶抵部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。
可将拉簧的第一端固定在推顶件620的主体上，或者直接固定在顶抵部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，还可在所述凸台部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，弹性件620a也可采用如扭簧，簧片等类型的弹性型件，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610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。
如图6所示，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。一般来说，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。
图16示出了依据本公开一些实施方式的冰箱的另一种结构的装配结构示意图；图17示出了图16中的开关门装置的联动轮与悬停机构的结构示意图；图18示出了图16中的开关门装置的限位机构的结构示意图。如图16、图17和图18所示，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，可采用另一种悬停装置600；第一卡合部600a可包括设置在在联动轮300上的悬停机构630，第二卡合部600b包括设置在底座900上的限位机构640，在联动轮300转动的情况下，悬停机构630跟随转动，从而在联动轮300转动到预设的开门位置时，悬停机构630可与限位机构640卡合，从而将联动轮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，维持在当前的预设开度状态。
如图16、图17、图18和图25所示，其中图25示出了图18中开关门装置的联动轮和悬停机构的结构示意图，在一些实施方式中，悬停机构630可包括连接部631和悬停部632，悬停部632通过连接部 631与联动轮300连接，从而悬停部632可跟随联动轮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，即联动轮300的制动力，从而将联动轮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，联动轮300继续转动，联动轮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开度。
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，从而制动联动轮300。在另一些实施方式中，可在限位部642上开设限位槽643，从而在悬停部632转动到限位槽643处时，能够自然卡合于限位槽643内，从而通过限位槽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轮300的制动力，可将悬停部632设置成独立的卡嵌件632a，且卡嵌件632a的形态设置成与限位槽643的槽型匹配的形态，从而在卡嵌件632a转动到限位槽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，便于良好匹配联动轮300的驱动力，形成流畅且稳定地联动轮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632a设置成可弹性形变件，从而在卡嵌件632a卡合在限位槽643的槽体内，形成一定的弹性接触压力，提升制动力，特别是在脱离限位槽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632a跟随联动轮300转动，卡嵌件632a的移动轨迹为弧形，可将限位槽643设置在卡嵌件632a的弧形轨迹上，并且偏向联动轮300的圆心的一侧，从而在卡嵌件632a转动到限位槽643的位置时，需要产生一定的形变才能够卡嵌进限位槽643内，相应地也需要产生一定的形变才能够脱离限位槽643，便于形成稳定的制动力。
在一些实施方式中，可在卡嵌件632a的头端设置可弹性变形的卡嵌头632a1，且卡嵌头632a1可形变嵌入或者脱离限位槽643。
在一些实施方式中，限位槽643设置成空心筒形件，限位槽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限位槽和悬停件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632a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。连接部可通过固定连接机构固定在联动轮300上，也可一体成型在联动轮300上。
在另一些实施方式中，卡嵌件632a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，第二卡合部600b还可包括连接在限位部642一侧的导向部641，在联动轮300转动过程中时，悬停部632可接触并沿导向部641移动，通过导向部641能够实现缓冲和导向，以引导悬停部632平滑卡合于限位槽643内，避免悬停部632由于惯性作用，无法稳定卡合落位到限位槽643内。
在一些实施方式中，导向部641可设置成与联动轮300的周面相切的导向平面641a，限位槽643设置于导向平面641a的一端，从而悬停部632在接触并沿着导向平面641a移动并直接落位卡嵌到限位槽643内。
值得说明的是，导向平面641a与悬停部632的弧形轨迹上的相切点可以设置在限位槽643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643内；在联动轮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，便于联动轮300的驱动器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连接臂631a，从而通过连接臂631a的弹性形变使得悬停部632可平滑稳定的卡合于限位槽643内，并在一个稳定的压迫力的作用下，即可脱离限位槽643，实现平滑顺畅的制动和解除制动操作。
为了保证悬停机构630的可靠性，连接臂631a的长度不宜过大，避免过度形变，影响悬停部632的受力状态，导致无法稳定卡合于限位槽643内，或者容易脱离限位槽643，劣化制动效果。
在一些实施方式中，还可在连接臂631a与联动轮300之间设置加强筋板633，以强化连接关系， 并一定程度上限制连接臂631a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。
在一些实施方式中，开关门装置还设置有用于突破门体13和箱体12之间的负压吸附等吸附力的顶门机构，顶门机构设置在联动轮300上，随着联动轮300转动以顶推门体13，突破吸附力之后，由转门机构400继续转动门体13，实现接力开门操作。
由转门机构400、顶门机构和悬停机构630都与联动轮300直接相连，为了降低各结构之间的干涉，可将转门机构400和悬停机构630分别布置在顶门机构的相对两侧；从而在顶门机构先顶开门体后，转门机构400和悬停机构630分别在保持一定距离的相对位置独立实现转门和悬停制动操作，互不干涉，实现空间上的和谐兼容，保证工作的顺畅平滑性和稳定性。
图12示出了图3中的开关门装置的顶门机构的另一种结构的装配结构示意图；图22示出了图18中开关门装置的顶门机构的初始状态的示意图。如图1、图12、图16和图22所示，在一些实施方式中，开关门装置还设置有用于突破门体13和箱体12之间的负压吸附等吸附力的顶门机构500，顶门机构500设置在联动轮300上，随着联动轮300转动以顶推门体13，突破吸附力之后，由转门机构400继续转动门体13，实现接力开门操作。
即，本公开一些实施方式提供两种顶门机构500的实现方式，且悬停装置600的实现方式也为两种，因此悬停装置600和顶门机构500的组合方式可分为四种。上文已经针对悬停装置600的实施方案进行说明，下面将分别对两种顶门机构500进行说明。
图8示出了图3中的开关门装置的顶门机构初始状态示意图；图9示出了图3中的开关门装置的顶门机构顶门状态示意图；图10示出了图3中的开关门装置的顶门机构初始状态示意图；图11示出了图3中的开关门装置的顶门机构的结构的示意图；图19示出了图18中开关门装置的初始状态的结构示意图；图20示出了图19中开关门装置的悬停机构的顶门状态的结构示意图；图21示出了图19中开关门装置的悬停状态的结构示意图。如图8、图9、图10、图11、图17、图19、图20和图21所示，在一些实施方式中，所述顶门机构500可包括顶门件520，且顶门件520可移动地设置在底座900上，联动轮300开设有抵持部310；在驱动器1000驱动联动轮300转动的条件下，抵持部310能够随着联动轮300转动，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。
在本公开一些实施方式中，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，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。在联动轮300上设置抵持部310，在联动轮300转动的条件下，抵持部310能够推动顶门件将对于箱体12移动，从而将门体13顶开，通过设置在联动轮300上的抵持部310直接和顶门件作用，能够直接顶开门体13，即可通过一个驱动结构驱动联动轮300转动，从而使顶门件顶开门体13，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。
在一些实施方式中，在联动轮300转动的条件下，顶门件不能跟随联动轮300转动，顶门件520能够在抵持部310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可与抵持部310的外表面贴合，在联动轮300转动的过程中，顶门件520在抵持部310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，在本公开一些实施方式中，顶门件520和抵持部310之间没有直接的连接关系，顶门件520可能与抵持部310接触，也可能与抵持部310不接触，在驱动结构驱动联动轮300转动时，顶门件520可与抵持部310抵持，并通过抵持部310推动顶门件520向靠近门体13的方向移动，以顶开门体13。
换言之，在本公开一些实施方式中，抵持部310跟随联动轮300转动，而顶门件520做直线运动。
为了方便描述，定义联动轮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轮300正转，转门机构400能够跟随联动轮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轮300反转，转门机构400能够跟随联动轮300反转，从而关闭门体13。
如图17所示，在一些实施方式中，抵持部310具有顶门面312，在抵持部310跟随联动轮300转动的条件下，顶门面312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312可设置在抵持部310的一侧，在抵持部310跟随联动轮300转动的过程中，顶门面312与顶门件抵持，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，抵持部310凸设在联动轮300上，则顶门面312上各处具有联动轮300的中 心的距离不同，由于顶门面312上各处到联动轮300的转动中心的距离不同，在联动轮300转动的过程中，顶门面312对抵持顶门件520向靠近门体13的方向移动，使顶门件520逐渐顶开门体13。
在一些实施方式中，顶门面312逐渐向远离联动轮300的转动中心的方向延伸；可以理解为顶门面312是倾斜设置的，在门体13关闭在箱体12上时，顶门件520设置在顶门面312与联动轮300的连接处，由于顶门面312向远离联动轮300的转动中心的方向凸设且倾斜设置，在联动轮300在驱动结构的驱动下转动时，顶门面312会抵持顶门件向靠近门体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312和联动轮300的转动中心的距离相关，为了方便描述定义顶门面312上具有联动轮300的转动中心最远的点为连接点316。若连接点316与联动轮300的转动中心的距离越远，则顶门件伸出的长度越长，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，该角度可以依据突破门体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312顶抵门体13的过程中，可能是在顶门面312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。
在一些实施方式中，抵持部310还包括避让面314，避让面314与顶门面312连接，在顶门件520与顶门面312脱离抵持后，顶门件520能够跟随避让面314复位。
在联动轮300正转的方向上，顶门面312设置在避让面314的前方，也就是说，在联动轮300转动的过程中，先是顶门面312和顶门件接触，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312脱离抵持后，顶门件520和避让面314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，若联动轮300上未设置避让面314，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314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。
当然，在顶门面312将顶门件顶抵至箱体12外后，在避让面314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314回收至箱体12上，可以在底座900和顶门件520上设置弹性复位件510，通过弹性复位件510的回复力，将顶门件520回收至箱体12上。
即在顶门面312在顶抵顶门件520的过程中，弹性复位件510逐渐产生形变，在连接点316和顶门件520接触时，弹性复位件510形变达到最大，在驱动结构驱动联动轮300继续转动的过程中，顶门件520与顶门面312脱离抵持，脱离抵持后，避让面314给顶门件提供了可回收至箱体12上的空间，在弹性复位件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，弹性复位件510可以是弹簧，也可以是扭簧，任选一种即可。
在弹性复位件510为弹簧的条件下，弹簧的一端与顶门件520连接，另一端可固定在底座900上，可以固定在联动轮300的连接轴上，在一些实施方式中，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。
若弹性复位件510为弹簧，在顶门面312在顶抵顶门件的过程中，弹簧逐渐被拉伸，在连接点316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轮300继续转动的过程中，顶门件520与顶门面312脱离抵持，脱离抵持后，避让面314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连接，在一些实施方式中，扭簧的中部分别与第一端及第二端连接，在顶门件顶开门体13时，顶门件需要克服扭簧的扭力。
若弹性复位件510为扭簧，在顶门面312顶抵顶门件520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312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314向远离门体13的方向运动，使顶门件520能够复位，避免顶门件520与门体13干涉，方便关门。
在一些实施方式中，顶门面312与避让面314连接于连接点316，连接点316与联动轮300的转动中心的距离大于避让面314及顶面面上任意一点到联动轮300的转动中心的距离。
在一些实施方式中，顶门面312与避让面314之间相互连接，可定义二者之间相互连接的点为连接点316，连接点316为顶门面312和避让面314上距离联动轮300的转动中心最远的点，在连接点316 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314转动顶门件520处后，避让面314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312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316和顶门件520接触时，顶门件520才打开门体13，在顶门面312跟随联动轮300转动的过程中，可能是顶门面312上的其中一个点在与顶门件520顶抵时，顶门件520顶开了门体13，只是在连接点316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轮300的转动速度相关，联动轮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314和顶门面312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；由顶门件先将门体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。
在联动轮300转动的过程中，悬停机构630卡入至限位机构640内，可使联动轮300停止转动，使转门机构400无法进一步地打开门体13，使门体13能够相对于箱体12停止转动。
如图11所示，在本实施方式中，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，使顶门件能够向靠近或远离门体13的方向运动。
在一些实施方式中，安装槽912的延伸方向可由联动轮300沿着至门体13，为了能够减少顶门件在顶门时，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，抵持部310和联动轮300一体成型。二者一体成型，相当于联动轮300直接和顶门件作用，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。
在一些实施方式中，联动轮300在驱动结构的带动下转动，通过抵持部310的设置，能够将转动转化为顶门件520的移动，通过联动轮300可实现在开门前的顶门，提高了联动轮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，本公开一些实施方式提供的开关门装置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。在联动轮300上设置抵持部310，在联动轮300转动的条件下，抵持部310能够推动顶门件将对于箱体12移动，从而将门体13顶开，通过设置在联动轮300上的抵持部310直接和顶门件作用，能够直接顶开门体13，即通过一个驱动结构可驱动联动轮300转动，从而使顶门件顶开门体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。
图13示出了图12中的开关门装置的顶门机构的顶门状态结构示意图；图14示出了图12中的开关门装置的顶门机构的悬停状态结构示意图；图15示出了图12中的开关门装置的联动轮的结构示意图；图23示出了图18中开关门装置的顶门机构的顶门状态的示意图；图24示出了图18中开关门装置的顶门机构的悬停状态的示意图。如图12、图13、图14、图15、图22、图23、图24和图25所示，在一些实施方式中，顶门机构还可设置成凸设于联动轮300上的顶门部350，在联动轮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关闭箱体12，即门体13吸附在箱体12上的情况下，顶门部350随着联动轮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和箱体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，在驱动器1000带动联动轮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1000带动联动轮300转动的过程中，顶门部350逐渐与门体13接触，在驱动器继续驱动联动轮300转动的条件下，顶门部350伸出至箱体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上距离联动轮300的转动中心最远的一点，在驱动器1000驱动联动轮300转动的过程中，顶门部350跟随联动轮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。
在一些实施方式中，外观面352为平面，顶面点设置在外观面352的一端，在驱动器驱动联动轮300转动的过程中，外观面352的一部分转动至箱体12上，另一部分转动至箱体12外，在箱体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跟随联动轮300转动的过程中，外观面352伸出至箱体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能够克服与箱体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与箱体12的开口齐平，在驱动器驱动联动轮300转动的过程中使顶门点351能够快速地转动至箱体12外，使顶门点351能够快速地顶开门体13。
在一些实施方式中，在门体13关闭的情况下，外观面352与箱体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。
依据本公开一些实施方式的冰箱，通过驱动器驱动联动轮带动转门机构转动门体，实现自动开关门；并通过联动轮正反转，带动转门机构动作推拉门体，实现开关门；通过在联动轮上设置第一卡合部和箱体上的第二卡合部形成悬停装置，作为联动轮制动的功能结构，悬停装置跟踪联动轮的转动位置，在联动轮转动到第一卡合部与第二卡合部相对的状态的情况下，通过第一卡合部与第二卡合部卡合，将联动轮锁定在底座上，实现联动轮的制动，以制动与联动轮相连的转门机构，从而实现门体悬停，保证门体开度的稳定，在降低开门难度的同时还方便使用，降低碰撞风险。
