具体实施方式
图1是根据本发明一个实施例的冰箱10的示意图。图2是根据本发明一个实施例的用于冰箱10的自动开关门装置的示意图，为便于观察自动开关门装置的安装位置，图2还示出了冰箱10的部分门体以及部分箱体。
本实施例的自动开关门装置可以适用于多种冰箱10，例如对开门冰箱、十字门冰箱、法式多门冰箱等。下述实施例将以对开门冰箱以及用于对开门冰箱的自动开关门装置为例，针对自动开关门装置以及具有其的冰箱10的具体结构进行详细阐述，本领域技术人员在了解下述实施例的基础上，应当完全有能力针对其他应用情况进行拓展，此处不再一一示例。
冰箱10一般性地可包括箱体110、门体120和自动开关门装置。箱体110内部可以形成有储物间室，储物间室可以为具有前向开口的储物空间。门体120可枢转地设置于箱体110，以封闭或打开前向开口，从而关闭或打开储物间室。本实施例的门体120可以为两个，镜像对称地设置于前向开口处，例如，其中第一门体可以用于封闭前向开口的左半部分，第二门体可以用于封闭前向开口的右半部分。两个门体的打开方向相对，例如前述第一门体的枢转轴可以位于其左侧，前述第二门体的枢转轴可以位于其右侧。图1箭头示出左右方向，其中“左”“右”等用于表示方位的词语，均是相对于冰箱10的实际使用状态而言的，大致可以为箱体110的水平横向延伸方向。
图3是图2所示的用于冰箱10的自动开关门装置的分解图。
自动开关门装置可以包括门体开闭机构和梁体翻转机构。
门体开闭机构用于受控地驱动冰箱10的门体120转动，从而开闭冰箱10的门体120。例如，门体开闭机构可以设置于箱体110上方。
梁体翻转机构包括翻转梁400和翻转拨杆510。其中翻转梁400用于可翻转地设置在冰箱10的门体120。翻转拨杆510用于受控可转动地设置于冰箱10的箱体110，从而在门体开闭机构开闭冰箱10门体120的过程中带动翻转梁400翻转。
门体开闭机构和梁体翻转机构的数量可以根据冰箱10的类型进行相应设置，对于对开门冰箱而言，门体开闭机构可以为两个，分别与一门体120对应设置，一门体开闭机构用于驱动一门体120转动。梁体翻转机构可以为一个，例如翻转梁400可以可翻转地连接至封闭前向开口左半部分的第一门体120，翻转梁400的第一端可以固定连接至第一门体120的右侧边缘部位，翻转梁400的第二端与第一端相对，且以第一端为转轴进行转动，从而实现翻转梁400的翻转。
翻转梁400和门体120均可以大致呈板状。翻转梁400可以根据门体120的开闭状态相对于门体120翻转。当门体120处于关闭位置时，翻转梁400所在板面与门体120所在板面之间的夹角可以大致为0°，在门体120从关闭位置向打开位置转动的过程中，翻转梁400可以相对于门体120转动，使得翻转梁400所在板面与门体120所在板面之间的夹角可以大致为90°，此时翻转梁400相对于门体120转动至翻折位置；在门体120从打开位置转动至关闭位置的过程中，翻转梁400可以相对于门体120再次转动，使得翻转梁400所在板面与门体120所在板面之间的夹角恢复至0°，此时翻转梁400相对于门体120转动至舒展位置。
通过利用门体开闭机构和梁体翻转机构相结合，本实施例提供了一种新的自动开关门装置，既能完成门体120的自动开闭，又能完成梁体的自动翻转，提高了门体120开闭过程的自动化程度。
门体开闭机构可以包括旋转机构200，还可以进一步地包括顶出机构。旋转机构200具有旋转作用件250。顶出机构具有顶出杆350。旋转机构200和顶杆机构300还分别设置有门体驱动电机210和门体传动组件。也就是说，本实施例的门体驱动电机210和门体传动组件分别为两个，其中一个门体驱动电机210和一个门体传动组件设置于旋转机构200中，另一个门体驱动电机210和另一个门体传动组件设置于顶杆机构300中。门体传动组件连接门体驱动电机210的输出轴与旋转作用件250或者顶出杆350，用于将门体驱动电机210提供的驱动力传递至旋转作用件250或者顶出杆350。
图4是图3所示的用于冰箱10的自动开关门装置的门体开闭机构中旋转机构200的内部结构图。
旋转机构200的各个部件可以设置于一旋转机构容纳盒。旋转机构200可以靠近门体120的枢转轴设置。旋转作用件250用于受控可转动地设置于冰箱10的箱体110且与冰箱10的门体120铰接，从而带动冰箱10的门体120转动。旋转作用件250可以与门体120的枢转轴通过铰链铰接，当旋转作用件250转动时，可以带动门体120的枢转轴转动，从而驱动门体120绕枢转轴转动以实现门体120的开闭。旋转作用件250可以为齿轮，其外周缘均匀分布有多个齿。且旋转作用件250一方面与门体传动组件啮合连接，另一方面与门体120的枢转轴啮合铰接。
旋转机构200的门体驱动电机210可以向旋转机构200提供驱动力。旋转机构200的门体传动组件连接门体驱动电机210的输出轴与旋转作用件250，用于将门体驱动电机210提供的驱动力传递至旋转作用件250，从而使得旋转作用件250受控转动。
图5是图3所示的用于冰箱10的自动开关门装置的门体开闭机构中顶出机构的内部结构图。
顶杆机构300的各个部件可以设置于一顶杆机构容纳盒。在门体120处于关闭位置的情况下，顶杆机构300可以顶开门体120。顶杆机构300设置于箱体110上，例如可以设置于旋转机构200与翻转拨杆510之间，且靠近门体120与翻转梁400相接的部位，以利用较小的作用力顶开门体120。
顶出杆350用于受控可伸缩地设置于冰箱10的箱体110，且配置成在旋转作用件250转动之前受控地伸出，以顶开门体120。顶出杆350可以沿其中心轴线方向伸出或者缩回。顶出杆350的中心轴线可以平行于箱体110的前后延伸方向。图1箭头示出箱体110的前后延伸方向，其中“前”“后”等用于表示方位的词语，均是相对于冰箱10的实际使用状态而言的。
顶出杆350上形成有沿其中心轴线方向排布的齿条351。该齿条351可以与门体传动组件啮合连接，从而使得门体传动组件将门体驱动电机210的驱动力传递至顶出杆350。
顶杆机构300的门体驱动电机210可以向顶杆机构300提供驱动力。顶杆机构300的门体传动组件连接门体驱动电机210的输出轴与顶出杆350，用于将门体驱动电机210提供的驱动力传递至顶出杆350，从而使得顶出杆 350受控伸缩。
顶杆机构300还可以包括复位弹簧360，沿顶出杆350的中心轴线方向设置于顶出杆350的后侧。且复位弹簧360的一端与顶出杆350固定连接，另一端与顶杆机构容纳盒的内壁(例如后壁)固定连接。复位弹簧360的伸缩方向与顶出杆350的中心轴线方向共线。且复位弹簧360配置成在顶出杆350受控地伸出以顶开门体120之后带动顶出杆350缩回，以防顶出杆350对门体120的关闭过程造成干涉。
在一些实施例中，顶杆机构300还可以包括接近传感器380，设置于顶出杆350的齿条351的前侧。顶出杆350做伸出运动时，其齿条351会随之前移。当顶出杆350的齿条351抵压于接近传感器380时，接近传感器380可以产生特定的电信号，门体驱动电机210在接收到接近传感器380的电信号之后可以切换至待机状态。
旋转机构200和顶杆机构300的门体驱动电机210以及门体传动组件的结构可以相同。其中门体驱动电机210可以为步进电机，但不限于此。门体传动组件可以为齿轮组，且可以包括门体第一传动齿轮211、门体第二传动齿轮212和门体第三传动齿轮213。
门体第一传动齿轮211连接至门体驱动电机210的输出轴。门体第一传动齿轮211可以与门体驱动电机210的输出轴啮合连接，门体驱动电机210的输出轴可以形成有与门体第一传动齿轮211的齿啮合的齿形条。在一些可选的实施例中，门体第一传动齿轮211与门体驱动电机210的输出轴之间的连接方式可以根据实际需要进行变换，例如，门体驱动电机210的输出轴可以连接至门体第一传动齿轮211的轴。
门体第二传动齿轮212与门体第一传动齿轮211啮合。门体第三传动齿轮213与门体第二传动齿轮212同轴，并与旋转作用件250或者顶出杆350传动连接。门体第三传动齿轮213的位置可以低于门体第二传动齿轮212的位置。且门体第三传动齿轮213的齿根圆直径大于门体第二传动齿轮212的齿根圆直径。也就是说，门体第三传动齿轮213的整体外形尺寸大于门体第二传动齿轮212的整体外形尺寸，这可以对门体驱动电机210的转动行程起到放大作用，利用小幅度的转动即可驱动顶出杆350产生较大的伸缩量，或者驱动旋转作用件250产生较大的转动量。
本实施例的门体传动组件还可以进一步地包括门体第四传动齿轮214， 用于将门体第三传动齿轮213传动连接至旋转作用件250或者顶出杆350。也就是说，门体第三传动齿轮213可以通过一门体第四传动齿轮214与旋转作用件250或者顶出杆350传动连接，例如门体第四传动齿轮214一方面可以与门体第三传动齿轮213啮合连接，另一方面可以与旋转作用件250啮合连接或者与顶出杆350啮合连接。在一些可选的实施例中，门体第三传动齿轮213与旋转作用件250或者顶出杆350之间的传动连接方式可以进行变换，例如，可以门体第三传动齿轮213可以直接与旋转作用件250啮合连接，或者与顶出杆350啮合连接。
通过对门体传动组件的多个传动齿轮进行有机连接，使得本实施例的自动开关门装置能够利用较小的驱动力和较小的电机转动行程即可实现门体120的开闭，这有利于降低门体开闭机构的开闭门体120的难度。
图6是图3所示的用于冰箱10的自动开关门装置中梁体翻转机构的示意图，图7是图6所示的用于冰箱10的自动开关门装置中梁体翻转机构的分解图。
除翻转梁400外，梁体翻转机构的其他部件可以组成翻转驱动组件500。图8是图6所示的用于冰箱10的自动开关门装置中梁体翻转机构的翻转驱动组件500的示意图。其中图8(a)示出翻转驱动组件500的内部结构，图8(b)为图8(a)中部分结构的剖视图。
梁体翻转机构的翻转拨杆510可以包括转轴部511和拨动部512。转轴部511用于带动拨动部512转动，拨动部512用于带动翻转梁400翻转。且梁体翻转机构还可以进一步地包括梁体驱动电机540、梁体传动组件以及盒体520。
翻转拨杆510的转轴部511用于受控可转动地设置于冰箱10的箱体110，例如可以设置于箱体110上方，且与翻转梁400的位置相对应，使得翻转拨杆510可以与翻转梁400接触以带动翻转梁400翻转。
翻转拨杆510的拨动部512与转轴部511固定连接或与转轴部511为一体件，以带动翻转梁400翻转。转轴部511与拨动部512的旋转轴线与转轴部511的中心轴线及拨动部512的中心轴线同轴。转轴部511的中心轴线以及拨动部512的中心轴线均可以沿竖直方向延伸。且拨动部512从转轴部511的至少一部分区段沿径向向外延伸，例如可以从转轴部511的中部区段沿径向向外延伸。
图9是图8所示的用于冰箱10的自动开关门装置中梁体翻转机构的翻转拨杆510的拨动部512的俯视图。
拨动部512可以形成有沿径向向外伸出的多个拨动凸起512a，其中，“径向”是相对于转轴部511的径向而言的。多个拨动凸起512a相对于拨动部512的中心轴线间隔均匀分布，且用于与翻转梁400配合以带动翻转梁400翻转。
例如本实施例的拨动凸起512a可以为三个，相邻拨动凸起512a之间的夹角可以为120°。拨动部512的整体外形可以大致类似于吊扇，拨动凸起512a可以大致类似于吊扇的扇叶，且具有厚度。每一拨动凸起512a配置成在冰箱10的门体120关闭过程中转动至相邻位置的另一拨动凸起512a处。也就是说，在门体120关闭过程中，驱动一拨动凸起512a转动120°，即可带动翻转梁400翻转至舒展位置。在门体120恢复至关闭位置且翻转梁400恢复至舒展位置时，拨动凸起512a静止，且用于带动翻转梁400翻转的拨动凸起512a的延伸方向可以平行于箱体110的左右延伸方向，图9中虚线示出箱体110的左右延伸方向。如此设置，在门体120打开过程中，任一拨动凸起512a均不会对翻转梁400的翻转造成干涉。也就是说，本实施例的翻转拨杆510仅需要在门体120关闭过程中带动翻转梁400翻转，这既有利于简化梁体翻转机构的控制过程，也可以减少翻转拨杆510与翻转梁400产生机械磨损。
值得说明的是，在了解本实施例的基础上，本领域技术人员应当易于根据实际情况适当调整拨动凸起512a的数量和转动角度的大小、以及拨动部512的位置和拨动凸起512a的形状尺寸，以上举例不应视为针对拨动凸起512a的数量和转动角度大小的限定。
梁体翻转机构的盒体520用于容置除翻转梁400之外的各个部件。梁体翻转机构的盒体520具有顶壁和底壁。顶壁和底壁大致可以为水平板壁状。其中底壁的上表面形成有上环形凸缘，上环形凸缘的中央形成有供转轴部511的底端伸入其中且可转动地配合的轴孔。顶壁的下方可以形成有环形固定件570，环形固定件570的中央形成有贯穿其厚度方向、以供转轴部511的顶端伸入其中且可转动地配合的另一轴孔。利用上环形凸缘的轴孔以及环形固定件570的轴孔分别与转轴部511的底端和顶端配合，可使转轴部511绕其中心轴线可靠地转动。
梁体驱动电机540用于为翻转拨杆510的转动提供驱动力。梁体传动组件用于将梁体驱动电机540的驱动力传递至翻转拨杆510。梁体传动组件可以连接梁体驱动电机540的输出轴与翻转拨杆510的转轴部511，用于将梁体驱动电机540提供的驱动力传递至翻转拨杆510的转轴部511，以驱动翻转拨杆510转动。转轴部511的顶端与梁体传动组件传动连接。
梁体传动组件包括相互啮合的梁体第一传动齿轮551和梁体第二传动齿轮552，其中梁体第一传动齿轮551连接至梁体驱动电机540的输出轴。梁体第一传动齿轮551可以与梁体驱动电机540的输出轴啮合连接，梁体驱动电机540的输出轴可以形成有与梁体第一传动齿轮551的齿啮合的齿形条。在一些可选的实施例中，梁体第一传动齿轮551与梁体驱动电机540的输出轴之间的连接方式可以根据实际需要进行变换，例如，梁体驱动电机540的输出轴可以连接至梁体第一传动齿轮551的轴。
梁体第二传动齿轮552的轴连接至翻转拨杆510的转轴部511。梁体第二传动齿轮552的轴可以位于转轴部511的上方。转轴部511的顶端可以穿过环形固定件570的轴孔，以与梁体第二传动齿轮552的轴固定连接。
翻转梁400可以包括翻转梁本体410和从翻转梁本体410的顶端向上凸出的导向杆420。翻转梁本体410的高度与门体120的高度可以大致相同。也就是说，翻转梁400的顶部还形成有向上凸出的导向杆420。盒体520内相应形成有供导向杆420伸入其中且可往复移动的导向槽，例如导向槽可以从盒体520的部分底壁向上凹陷形成。导向杆420配置成在冰箱10的门体120关闭过程中由拨动部512带动沿导向槽移动，从而使得翻转梁400翻转。导向槽的位置可以与翻转拨杆的安装位置邻近设置。
本实施例的用于冰箱10的自动开关门装置以及具有其的冰箱10，其中自动开关门装置包括门体开闭机构和梁体翻转机构。门体开闭机构用于受控地驱动冰箱10的门体120转动，梁体翻转机构包括用于可翻转地设置在门体120的翻转梁400以及用于受控可转动地设置于冰箱10的箱体110的翻转拨杆510，从而可以在门体开闭机构开闭门体120的过程中利用翻转拨杆510带动翻转梁400翻转。通过利用门体开闭机构和梁体翻转机构相结合，本实施例提供了一种新的自动开关门装置，既能完成门体120的自动开闭，又能完成梁体的自动翻转，提高了门体120开闭过程的自动化程度。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明 的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
