具体实施方式
下面将结合本公开的一些实施例中的附图，对本公开的一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的一些实施例，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例，都属于本公开保护的范围。

在本公开的一些实施例的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，包括固定连接，或可拆卸连接，或一体连接等。术语“和/或”，既包括“和”，又包括“或”；例如，A和/或B，包括：A，B，以及A和B三种。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本公开中的具体含义。在上述实施方式的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开的一些实施例的描述中，除 非另有说明，“多个”的含义是两个或两个以上。
相关技术中，冰箱中的抽屉通常设置在较为接近地面的位置，这样在使用抽屉以取放食物的过程中，用户需要做出大幅度的弯腰或下蹲的动作，容易造成用户使用不便。并且，若从抽屉内取出或放入抽屉内的食物较重，容易发生用户腰部肌肉损伤的情况。
基于此，请参阅图1～图5，本公开的一些实施例提供了一种冰箱100。该冰箱100包括箱体1；与箱体1可抽拉连接的至少一个抽屉底座2；设置在所述至少一个抽屉底座2中的每个内的一第一储物部3；以及，设置在每个抽屉底座2和对应的第一储物部3之间的一升降机构4。
箱体1构成冰箱100的外部轮廓，其内部具备至少一个储藏室11，所述至少一个储藏室11中的每个内设置有一个抽屉底座2。储藏室11例如包括维持于冷藏温度带的冷藏室或蔬菜室，或者，还例如包括维持于冷冻温度带的冷冻室或制冰室等。
每个抽屉底座2位于对应的储藏室11内并与对应的升降机构4连接。每个抽屉底座2配置为承载对应的第一储物部3，其结构具有多种选择。示例性的，每个抽屉底座2采用外形较为规则的框架结构，例如外形呈长方体的方框结构，或外形呈半圆柱体的半圆框结构等。示例性的，每个抽屉底座2采用外形不规则的框架结构，例如侧壁弯折或具有镂空区域的异形结构。
第一储物部3位于对应的储藏室11内且配置为存储食物，第一储物部3的结构与对应的抽屉底座2的结构匹配设置。通常，第一储物部3的外形尺寸小于对应的抽屉底座2的外形尺寸，这样第一储物部3的部分或全部便可位于对应的抽屉底座2的内部空间内。
上述冰箱100还包括与每个抽屉底座2固定连接且配置为封闭对应的储藏室11的抽屉门板6，以及设置于每个储藏室11内并与储藏室11可抽拉连接的第二储物部7；第二储物部7位于同一储藏室11内第一储物部3的背离抽屉底座2的一侧，也即如图1所示的第一储物部3的上方。
第二储物部7与抽屉门板6之间没有连接，由此，在抽拉抽屉门板6的情况下，承载第一储物部3的抽屉底座2随抽屉门板6的移动而移动，第二储物部7不随抽屉门板6移动。这样在使用第二储物部7的过程中，用户可以手动将第二储物部7抽出储藏室11，以实现食物在第二储物部7内的取放。通过设置依次层叠的第一储物部3和第二储物部7，可以使食物分区更加精细化。
每个抽屉底座2与箱体1之间可抽拉连接的方式和抽屉底座2的结构相关。以下以抽屉底座2的结构采用如图5所示的结构为例，对其与箱体1之间的可抽拉连接进行示意说明。
请参阅图5，抽屉底座2包括底壁、以及围设在底壁周边的并与底壁连接的至少两个侧壁。例如，抽屉底座2包括底壁、左侧壁和右侧壁，该底壁、左侧壁和右侧壁共同构成U型框架结构。
在一些示例中，每个抽屉底座2与箱体1之间通过接触滑动实现可抽拉连接。
每个抽屉底座2的左侧壁和右侧壁二者背离底壁的一端，分别向外延伸并形成开口向下的U形翻边。箱体1上设置有与左侧壁的U形翻边和右侧壁的U形翻边分别 匹配设置的条状滑条。这样将每个抽屉底座2的U形翻边搭接到对应的条状滑条上，便可以通过该U形翻边和对应的条状滑条之间的相对滑动，实现每个抽屉底座2与箱体1之间的可抽拉连接。
在另一些示例中，请参阅图1～图3，每个抽屉底座2和箱体1之间通过滑轨组件实现可抽拉连接。
示例性的，滑轨组件包括电动滑轨组件5。
请参阅图2～图3，电动滑轨组件5，包括主动滑轨组件51、从动滑轨组件52、与主动滑轨组件51连接的滑轨驱动组件以及分别与主动滑轨组件51和从动滑轨组件52连接的同步组件53，其中，主动滑轨组件51和从动滑轨组件52对称安装于抽屉底座2的两侧(抽屉底座2的左侧壁和右侧壁)，并分别与箱体1连接。
主动滑轨组件51和从动滑轨组件52结构相同，此处，以主动滑轨组件51为例，描述其结构。请参阅图3，主动滑轨组件51包括固定导轨511、与固定导轨511滑动连接的连接导轨512、与连接导轨512滑动连接的滑动导轨513、配置为将固定导轨511与箱体1连接的呈U形的固定导轨支架514、以及配置为将滑动导轨513与对应的抽屉底座2连接的滑动导轨支架515。滑轨驱动组件包括驱动齿轮541、驱动齿条542、内置触摸芯片的触摸板、减速电机543和控制器。减速电机543安装于主动滑轨组件51的固定导轨511的前端外侧。驱动齿轮541安装于减速电机543的输出转动轴上。驱动齿条542安装于主动滑轨组件51的滑动导轨支架515上。驱动齿轮541啮合安装于驱动齿条542上。内置触摸芯片的触摸板通常安装于对应的抽屉门板6上。减速电机543与控制器电控连接，内置触摸芯片的触摸板与控制器电控连接。控制器集成在抽屉门板上，控制器能够根据接收到的内置触摸芯片的触摸板发出的触摸信号来控制减速电机543驱动上述驱动齿轮541沿驱动齿条542带动滑动导轨支架515以及滑动导轨513作水平移动，从而实现了抽屉底座2与箱体之间的可抽拉连接。
通过电动滑轨5实现抽屉底座2与箱体1之间的可抽拉连接，可以提高冰箱100的自动化程度，使冰箱100更便于使用。
第二储物部7与储藏室11之间的可抽拉连接，通常采用与第一储物部3与储藏室11之间的可抽拉连接相同的方式，可以简化冰箱100的生产流程，提高其生产效率。
在一些实施例中，上述升降机构4包括至少一个伸缩架41，所述至少一个伸缩架41中的每个伸缩架41包括至少一组铰杆组件411，所述至少一组铰杆组件411中的每组铰杆组件411包括中部互相铰接的第一铰杆4111和第二铰杆4112。
第一铰杆4111和第二铰杆4112结构相同，能够采用相同的材料制作成型。第一铰杆4111和第二铰杆4112的中部互相铰接，表现为：两者相互交叉，并将其重合的位置作为铰接点铰接在一起，以构成形状为X形的结构。这样可以使铰杆组件411受力较为均匀，结构较为稳定，不易被损坏。
在一些示例中，升降结构4包括一个伸缩架41。该伸缩架41的每组铰杆组件411中的第一铰杆4111和第二铰杆4112，在垂直于各自的杆长方向的截面呈长条状，这样可以增大该伸缩架41与抽屉底座2以及其与第一储物部3之间的接触面积，从而确保该伸缩架41对第一储物部3形成稳定的支撑。
在另一些示例中，升降结构4包括至少两个伸缩架41。请参阅图5，所述至少两 个伸缩架41平行且间隔设置。这样利用上述至少两个伸缩架41可以对第一储物部3形成较为均匀且较为稳定的多个点支撑，有利于使第一储物部3的上升或下降的过程更为平稳。此外，示例性的，所述至少两个伸缩架41之间的平行设置的方向(也即如图5所示的外侧的伸缩架41指向里侧的伸缩架41的方向，或里侧的伸缩架41指向外侧的伸缩架41的方向)与抽屉底座2的可抽拉方向相同。
上述各伸缩架41包括的铰杆组件411的数量与对应的第一储物部3所需上升的高度相关，可以根据实际需要选择设置，本公开的一些实施例对此不做限定。
在一些示例中，请参阅图4～图5，每个伸缩架41包括一组铰杆组件411。所述铰杆组件411中的第一铰杆4111的下端与抽屉底座2铰接，第一铰杆4111的上端与第一储物部3滑动连接。所述铰杆组件411中的第二铰杆4112的下端与抽屉底座2滑动连接，第二铰杆4112的上端与第一储物部3铰接。
此处，第一铰杆4111的下端与抽屉底座2之间的铰接，以及第二铰杆4112的上端与第一储物部3之间的铰接的方式相同或不同。
在一些示例中，第一铰杆4111的下端与抽屉底座2之间的铰接，以及第二铰杆4112的上端与第一储物部3之间的铰接采用相同的方式实现，例如采用铰接结构44来实现。
以下以第一铰杆4111的下端和抽屉底座2之间采用铰接结构44铰接为例，进行铰接结构44的一种结构的示意性说明。
请继续参阅图4～图5，第一铰杆4111的下端与抽屉底座2之间设置有铰接机构44。该铰接机构44包括两个相对设置且与抽屉底座2固定连接的定位小板441，以及一轴销442。每个定位小板441上开设有配置为安装轴销442的连接孔，轴销442通常采用固定连接或转动连接的方式安装在两连接孔内。第一铰杆4111的下端开设有与两连接孔匹配设置且供轴销442穿过的通孔，轴销442与第一铰杆4111之间采用转动的方式连接。这样通过将第一铰杆4111的下端插入两个定位小板441之间，使第一铰杆4111的通孔与两个定位小板441的连接孔相对应，然后安装轴销442，便可以实现第一铰杆4111的下端和抽屉底座2之间的铰接。这样既可以使得第一铰杆4111以对应的轴销442为定点转动，还可以限定了第一铰杆4111的活动范围。
当然，铰接机构44还可以采用其他结构，以能够实现第一铰杆4111的下端与抽屉底座2之间的铰接、或第二铰杆4112的上端与第一储物部3之间的铰接即可，本公开的一些实施例对此不作限定。
在使用上述冰箱的过程中，若需要取放食物，提拉第一储物部3，这样第一铰杆4111的上端会受到沿垂直于第一铰杆4111的杆长方向的提拉分力，使得第一铰杆4111沿背离抽屉底座2的方向绕与其下端对应的轴销442转动，进而使第一铰杆4111的上端向靠近第二铰杆4112上端的方向滑动，同时使第一铰杆4111与第二铰杆4112发生相对转动，并带动第二铰杆4112的下端向靠近第一铰杆4111下端的方向滑动，使铰杆组件441展开(也即在沿第一储物部3的升降方向上伸长)。
在取放完食物之后，按压第一储物部3，第一铰杆4111的上端受到沿垂直于第一铰杆4111的杆长方向的按压分力，使得第一铰杆4111沿靠近抽屉底座2的方向绕与其下端对应的轴销442转动，进而使得第一铰杆4111的上端向远离第二铰杆4112上 端的方向滑动，同时使第一铰杆4111与第二铰杆4112发生相对转动，并带动第二铰杆4112的下端向远离第一铰杆4111下端的方向滑动，使铰杆组件441收拢(也即在沿第一储物部3的升降方向上缩短)。
在另一些示例中，请参阅图11，每个伸缩架41包括沿第一储物部3的升降方向顺次铰接的至少两组铰杆组件411。所述至少两组铰杆组件411中，靠近抽屉底座2的铰杆组件411中的第一铰杆4111与抽屉底座2铰接，第二铰杆4112与抽屉底座2滑动连接；靠近第一储物部3的铰杆组件411中的第一铰杆4111与第一储物部3滑动连接，第二铰杆4112与第一储物部3铰接。
此处，每组铰杆组件411的结构与上述一些实施例中铰杆组件411的结构相同。并且，靠近抽屉底座2的第一铰杆4111与抽屉底座2之间的铰接，以及靠近第一储物部3的第二铰杆4112与第一储物部3之间的铰接，均可采用与上述一些实施例中铰接相同的方式。
请继续参阅图11，所述两组铰杆组件411的顺次铰接，表现为：在沿第一储物部3的升降方向上的相邻两组铰杆组件411中，靠近抽屉底座2的一组铰杆组件411的第一铰杆4111的上端与靠近第一储物部3铰杆组件411的第二铰杆4112的下端铰接，靠近抽屉底座2的铰杆组件411的第二铰杆4112的上端与靠近第一储物部3铰杆组件411的第一铰杆4111的下端铰接。
这样在提拉第一储物部3以使第一储物部3上升的过程中，或在按压第一储物部3以使第一储物部下降的过程中，靠近第一储物部3的一组铰杆组件411会产生与前述一些实施例中相同的受力情况，该组铰杆组件411会依次带动与其铰接的其他铰杆组件4111逐一转动，使伸缩架41展开或收拢。
在第一储物部3所需上升的高度一定，且每个伸缩架41包括至少两组铰杆组件411的情况下，每组铰杆组件411中的第一铰杆4111的长度和第二铰杆4112的长度可以较短，这样有利于减少每个伸缩架41在垂直于第一储物部3的上升方向的空间占用。
在本公开的一些实施例中，设置包括至少一组铰杆组件411的伸缩架41，并将至少一个伸缩架41设置在每个抽屉底座2和对应的第一储物部3之间，便可以利用所述至少一个伸缩架41中的每个伸缩架41的展开或收拢，实现对应的第一储物部3在垂直于抽屉底座2的底壁方向上的升起或下降。
在本公开的一些实施例提供的冰箱100中，升降机构4的每组铰杆组件411呈X形，构成剪叉式结构，这样可以使得升降机构4受力均匀，结构稳定，不易被损坏，有效提高升降结构4的升降功能的可靠性。另外，本公开的一些实施例提供的冰箱100的升降机构4结构简单、设计精巧且成本较低，易于实现，安全性高。
在一些实施例中，请参阅图12～图13以及图16～图18，第一储物部3包括储物盒31以及配置为承载储物盒31的托盘32。储物盒31可拆卸地放置在托盘32上，这样便于将储物盒31从托盘32上取下或安装，方便对储物盒31进行清洁。托盘32与靠近其的铰杆组件411中的第一铰杆4111的上端滑动连接，并与靠近其的铰杆组件411中的第二铰杆4112的上端铰接。
在一些示例中，储物盒31采用非金属材料制作形成，托盘32采用金属材料制作 形成。
在一些实施例中，请参阅图16～图18，储物盒31敞口设置，储物盒31的盒口311处具有第一翻边312(也即储物盒31的盒口向外延伸所形成的外翻边)。储物盒31还包括设置在第一翻边312上的至少一个定位开口313，抽屉底座2还包括与所述至少一个定位开口313中的每个匹配设置的第二定位凸起21，该第二定位凸起21如图14所示，其中图14为图13中C区域的放大示意图，第二定位凸起21配置为在第一储物部3下降到预定位置的情况下插接于对应的定位开口313内，此时，第一翻边312搭接于抽屉底座2的顶端上。这样在第一储物部3下降到预定位置的情况下，可以避免储物盒31与抽屉底座2之间产生相对位移，使储物盒31和抽屉底座2之间的位置更加固定。
在一些实施例中，请参阅图13、图16和图17，托盘32具有第二翻边321(也即托盘32的外边缘向上延伸形成的上翻边)，第二翻边321环绕储物盒31的盒壁314设置，并与储物盒31的盒壁314相抵靠。这样可以使储物盒31较为稳定的承载在托盘32上，避免储物盒31从托盘32上脱落。
请参阅图17和图18，储物盒31还包括设置在其盒底315的至少一个第三定位凸起316，托盘32还包括与所述至少一个第三定位凸起316中的每个匹配设置的定位凹槽322，所述至少一个第三定位凸起113中的每个配置为在托盘32承载储物盒31的情况下，卡入对应的定位凹槽322内。这样可以进一步的使储物盒31稳定承载在托盘32上，防止储物盒31因晃动或抖动而从托盘31上脱落。
在一些实施例中，请参阅图4～图6，升降机构4还包括：设置在抽屉底座2和与其滑动连接的每个第二铰杆4112之间的滑动机构43，和/或，设置在第一储物部3和与其滑动连接的每个第一铰杆4111之间的滑动机构43。滑动机构43的结构如图6所示(图6为图5中B区域的放大示意图)，滑动机构43包括滑槽431，滑槽431的结构根据实际需要选择设置，本公开的一些实施例对此不做限定。示例性的，滑槽431的结构为U型结构，或者为H型结构。
基于此，在一些示例中，滑动机构43设置于抽屉底座2和对应的第二铰杆4112之间，该第二铰杆4112的靠近抽屉底座2的一端伸入对应的滑槽431内，且能够在滑槽431内沿第一储物部3的升降方向垂直的方向滑动。在另一些示例中，滑动机构43设置于第一储物部3和对应的第一铰杆4111之间，该第一铰杆4111的靠近第一储物部3的一端伸入对应的滑槽431内，且能够在滑槽431内沿第一储物部3的升降方向的垂直方向滑动。
上述第二铰杆4112的伸入对应的滑槽431的部分，以及，上述第一铰杆4111的伸入对应的滑槽431的部分，具有与各自对应的滑槽431相匹配的结构，或者连接有至少一个滑动件(例如滚轮)，以便于使第二铰杆4112和第一铰杆4111均能够在各自对应的滑槽431内良好的滑动。
上述滑槽431通常具有一定的长度，该长度的设定与第一储物部3需要上升的高度相关，通过限定滑槽431的长度，可以使第二铰杆4112的靠近抽屉底座2的一端和第一铰杆4111的靠近第一储物部3的一端分别在对应的滑槽431的长度范围内滑动，进而限定每个铰杆组件411的转动范围。
在另一些实施例中，请参阅图6，滑动机构43还包括滑块432，滑块432设置于滑槽431内，且可在滑槽431内滑动。
相应的，在一些示例中，滑动机构43设置于抽屉底座2和第二铰杆4112之间，第二铰杆4112的靠近所述抽屉底座2的一端与对应的滑块432铰接，该滑块432配置为在滑槽431内沿垂直于第一储物部3的升降方向滑动。在另一些示例中，滑动机构43设置于第一储物部3和第一铰杆4111之间，第一铰杆4111的靠近第一储物部3的一端与对应的滑块432铰接，该滑块432配置为在滑槽431内沿垂直于第一储物部3的升降方向滑动。
本公开的一些实施例，将第二铰杆4112的靠近抽屉底座2的一端或第一铰杆4111的靠近第一储物部3的一端与对应的滑块432铰接，这样可以使得第二铰杆4112的靠近抽屉底座2的一端或第一铰杆的靠近第一储物部3的一端通过滑块432在滑槽431内滑动，无需再将第二铰杆的靠近抽屉底座2的一端或第一铰杆的靠近第一储物部3的一端设置成与对应的滑槽431相匹配的结构，有利于简化各铰杆的制作工艺。
本公开的一些实施例仅以滑动机构43采用滑槽431和滑块432为例进行说明，当然滑动机构43还可以是其他结构，只要能够实现第二铰杆4112的靠近抽屉底座2的一端与抽屉底座2之间、或第一铰杆4111的靠近第一储物部3的一端与第一储物部3之间的相对滑动即可，例如滑动机构43采用导柱和导套匹配滑动的结构。
在上述一些实施例中，请参阅图7～图9，滑动机构43还包括自锁结构，该自锁结构配置为在第一储物部3上升至预设高度后，对滑动机构43中的滑块432进行锁定，以避免第一储物部3上升起至预设高度的情况下，由于第一储物部3及其内所存储的食物的重力作用，使得滑块432向远离对应的铰接结构44的方向回滑的情况发生，有利于使第一储物部3保持在预设高度。
自锁结构通常具有多种结构，可以根据实际需要选择设置，本公开的一些实施例对此不做限定。
在一些示例中，请参阅图9，自锁结构包括：设置于滑槽431的槽壁4311上的至少一个卡孔4312，以及，设置于滑块432上且与所述至少一个卡孔4312匹配设置的至少一个弹簧卡珠4321，所述至少一个弹簧卡珠4321配置为在卡入对应卡孔4312的情况下，锁定滑块432。
在实际设计的过程中，弹簧卡珠4321的数量通常为偶数个，且该偶数个弹簧卡珠4321对称设置在对应的滑块432的两个侧面，这样可以确保自锁结构的平稳性。
由于弹簧卡珠4321为球形，这样便于使弹簧卡珠4321卡入对应的卡孔4312内，且在需要解除锁定的情况下，也便于使弹簧卡珠4321从对应的卡孔4312内滑出。需要说明的是，解除锁定机构的锁定所需的力大于第一储物部3及其内所存储的食物的重力所给予锁定机构的力。
本公开的一些实施例中所使用的弹簧卡珠4321是标准件，可以直接选用，这样便于对弹簧卡珠4321进行加工，简化滑动机构43的制备工艺。
在另一些示例中，请参阅图7，滑槽431的底壁4313包括滑动段A1以及相对于滑动段A1下沉的定位段A2。上述自锁结构包括：定位段A2，以及，设置在滑块432的靠近滑槽431的底壁4313的表面上的第一定位凸起4322，第一定位凸起4322配置 为在滑入定位段A1的情况下与定位段A2卡合，以限制滑块432向滑动段A1方向的位移。
定位段A2相对于滑动段A1下沉，也即如图7所示，定位段A2的朝向滑块432的表面位于滑动段A1的朝向滑块432的表面下方，且两表面呈一定的夹角连接。
在滑块432在滑槽431内沿第一方向滑动使第一储物部3被升起至预设高度的过程中，第一定位凸起4322配合卡入定位段A2内，这样可以利用定位段A2给予第一定位凸起4322的沿第一方向的力阻止滑块432在滑槽431内沿第二方向滑动，进而可以使得第一储物部3被上升至预设高度后锁定其所在位置。
在实际设计的过程中，在自锁结构的锁定状态下，第一定位凸起4322与定位段A2的接触面积通常为最大，且与滑块432连接的铰杆与定位段A2所在平面垂直，这样有利于提高自锁结构的锁定效果。在一些实施例中，请参阅图8，在自锁结构包括定位段A2和第一定位凸起4322的基础上，滑动机构43还包括设置在滑块432的靠近滑槽431的底壁4313的表面上的支点凸起4323。在第一定位凸起4322滑入定位段A2的情况下，支点凸起4323位于滑动段A1，支点凸起4323配置为使滑块4322绕支点凸起4323转动，并使第一定位凸起4322从定位段A2脱出。这样在第一储物部3被升起至预设高度的情况下，在给滑块432一个朝向背离对应的铰接结构44的方向的拉力的过程中，由于第二铰杆4112的下端或第一铰杆4111的上端与滑块432铰接，第二铰杆4112的下端或第一铰杆4111的上端也会给滑块432一个向上的拉力，使得滑块432绕支点凸起4323转动，进而使得第一定位凸起4322从定位段A2内脱出。
在一些实施例中，请参阅图9，滑动机构43还包括设置在滑槽431的槽口上的盖板433，该盖板433具有开口4331，该开口4311配置为供对应的第二铰杆4112或第一铰杆4111伸入滑槽431内且沿滑槽431滑动，由此，开口4331在沿对应的第二铰杆4112或第一铰杆4111滑动的方向具有一定的长度。盖板433配置为限制滑槽431内的滑块432沿垂直于滑槽431的底壁4313方向上的位移。这样可以将滑块432限位在底壁4313和盖板433之间，避免发生由于给滑块432的背离对应的铰接结构44的方向的拉力较大，导致滑块432绕支点凸起4323转动的幅度过大，进而导致滑块432旋出滑槽431的情况，进而可以避免滑动机构43的结构受到破坏。
在一些实施例中，请参阅图13，滑动机构43还包括分别设置在滑槽431的沿滑块432的滑动方向的两端的限位挡板434，限位挡板434配置为限制滑块432沿其滑动方向的位移。在滑块432滑动到滑槽431的两端中的某一端的情况下，可以利用限位挡板434将滑块432挡在滑槽431内，使滑块432不能再继续滑动，这样可以将滑块432限位在滑槽431内，避免滑块432滑出滑槽431。
在一些实施例中，请参阅图19，升降结构4包括至少两个伸缩架41，且升降结构4还包括至少一根同步推杆45。所述至少一根同步推杆45中的每根设置在相邻的两个伸缩架41之间。
在一些示例中，在沿平行于所述至少两个伸缩架41的平行设置的方向上，每根同步推杆45与靠近抽屉底座2的两组铰杆组件411中的第二铰杆4112连接。可选的，每根同步推杆45与对应的第二铰杆4112直接连接(例如，铰接或固定连接)，或间接连接(例如，同步推杆45通过滑块432与对应的第二铰杆4112连接)。
在另一些示例中，在沿平行于所述至少两个伸缩架41的平行设置的方向上，每根同步推杆45与靠近第一储物部3的两组铰杆组件411中的第一铰杆4111连接。可选的，每根同步推杆45与对应的第一铰杆4111直接连接(例如，铰接或固定连接)，或间接连接(例如，同步推杆45通过滑块432与对应的第一铰杆4111连接)。
此外，同步推杆45与对应的第二铰杆4112或第一铰杆4111在直接连接情况下的连接位置，可以根据需要选择设置，本公开的一些实施例对此不做限定。例如，每根同步推杆45的一端与对应的第二铰杆4112(或第一铰杆4111)的除其伸入对应的滑槽431的一端以外的部分连接。或者，例如，每根同步推杆45的一端与对应的第二铰杆4112(或第一铰杆4111)的伸入对应的滑槽431的一端连接，基于此，与上述两个滑槽431的相对的槽壁4311上设置有条形开口，该条形开口配置为供同步推杆45穿过并与对应的第二铰杆4112(或第一铰杆4111)的伸入滑槽431的一端连接，以及供同步推杆45沿与第一储物部3的升降方向垂直的方向滑动，以使两伸缩架41能够同步展开或同步收拢。
同步推杆45与对应的第二铰杆4112或第一铰杆4111在间接连接情况下的连接位置，可以根据需要选择设置，本公开的一些实施例对此不做限定。示例性的，每根同步推杆45设置在对应的两个滑动机构43之间，该两个滑动机构43中的两个滑槽431相对的侧壁4311上设置有条形开口，该条形开口配置为供同步推杆45穿过并与对应的第二铰杆4112(或第一铰杆4111)通过对应的滑块432连接。每根同步推杆45与对应的两滑块432之间采用铰接或固定连接的方式连接。
本公开的一些实施例，通过在相邻的两个伸缩架之间设置一根同步推杆45，可以使相邻的两个伸缩架41在展开或收拢的过程中发生联动，并使两个伸缩架41得展开程度或收拢程度保持一致，这样有利于确保第一储物部3的上升或下降的稳定性。
在一些实施例中，请参阅图10，在同步推杆45与滑块432对应连接的基础上，该滑块432所在滑槽431的侧壁4311上具有一限位凸出部43111。这样当滑块432在滑槽431内沿远离对应的铰接结构44的方向滑至滑槽431的端部的过程中，若同步推杆45遇到限位凸出部43111，则可以利用限位凸出部43111对同步推杆45的限位，确保滑块432不能再继续滑动，也即确保滑块432不会滑出滑槽431。
在一些实施例中，请参阅图19，升降机构4还包括至少一根同步连杆46，所述至少一根同步连杆46中的每根设置于相邻的两个伸缩架41中平行设置的两组铰杆组件411之间。示例性的，每根同步连杆46在所述两组铰杆组件411之间的设置方式，表现为同步连杆46的两端分别与两组铰杆组件411的铰接点连接。这样可以进一步增加升降机构4的结构稳固性。
在上述实施例中，请参阅图4～图5，升降结构4还包括至少一个驱动模块42，所述至少一个驱动模块42中的每个与至少一个伸缩架41对应设置。也即，每个驱动模块42能够为至少一个伸缩架41提供驱动，以使该至少一个伸缩架41在对应的驱动模块42的驱动下展开或收拢，进而带动第一储物部3上升或下降，这样有利于提高升降结构4的自动化程度。
在一些示例中，每个驱动模块42包括驱动部421和输出部422，其中，驱动部421配置为驱动输出部422自驱动部421伸出或缩回，进而通过输出部422带动对应的伸 缩架41展开或收拢。
示例的，上述驱动模块42包括推杆电机。该推杆电机包括电动机(即驱动部)以及与电动机连接的推杆(即输出部)，该推杆能够在电动机的转动下自电动机伸出缩回。此处，驱动模块42还可以包括其他驱动装置，例如带有气压杆的气缸或者带有液压杆的液压装置、慢开电磁阀、步进电机带动曲柄滑块机构或齿轮齿条机构等。
每个驱动模块42为对应的伸缩架41提供的驱动所作用的位置可以根据需要选择设置，本公开的一些实施例对此不做限定。
在一些示例中，每个驱动模块42配置为驱动对应伸缩架41中与抽屉底座2滑动连接的第二铰杆4112沿第一储物部3的升降方向的垂直方向滑动，以使第一储物部3升起或下降。
也就是说，每个驱动模块42的输出部422作用在对应的伸缩架41中与抽屉底座2滑动连接的第二铰杆4112上，这样在驱动部421驱动输出部422自驱动部421伸出的情况下，会带动该第二铰杆4112的下端向靠近对应的铰接结构44的方向滑动，使对应的伸缩架41展开，进而使第一储物部3上升。在驱动部421驱动输出部422自驱动部421缩回的情况下，会带动该第二铰杆4112的下端向远离对应的铰接结构44的方向滑动，使对应的伸缩架41收拢，进而使第一储物部3下降。
在另一些示例中，每个驱动模块42配置为驱动对应伸缩架41中与第一储物部3滑动连接的第一铰杆4111沿第一储物部3的升降方向的垂直方向滑动，以使第一储物部3升起或下降。也即每个驱动模块42的输出部422作用在对应的伸缩架41中与第一储物部3滑动连接的第一铰杆4111上，这样每个驱动模块42便可以通过驱动输出部422的伸出或缩回，使第一储物部3升起或下降。
在一些示例中，每个驱动模块42的驱动部421还和上述一些实施例中的控制器连接(包括电连接或信号连接等)，这样在需要将抽屉底座2从箱体1内拉出，并使该抽屉底座2内的第一储物部3升起的情况下，便可以通过内置触摸芯片的触摸板发出相应的信号至控制器，使控制器驱动电动滑轨组件5带动抽屉底座2滑出箱体1，然后使控制器控制对应的驱动模块42的驱动部421驱动输出部422自驱动部421伸出，带动对应的伸缩架41展开，使第一储物部升起。这样有利于进一步提高冰箱100的自动化程度，提高用户体验感。
在一些实施例中，每个驱动模块42还包括定位结构，该定位结构配置为限制输出部422自驱动部421伸出或缩回的长度，以控制对应的第一储物部3的升降高度。
示例性的，定位结构包括限位块或限位阀等。定位结构通常与驱动部421的电源连接。这样在驱动模块42的驱动部421驱动输出部422自驱动部421伸出或缩回任意长度后，通过限位块断开驱动部421的电源，便可控制驱动部421停止对输出部422的驱动，并使输出部422的伸出或缩回的长度维持在驱动部421停止驱动时所对应的长度，从而对第一储物部3的升降高度进行控制。
此外，上述定位结构还能够作为对应滑动机构43的一种自锁结构，也即在第一储物部上升至预设高度后，通过定位结构423对输出部422的伸出长度进行定位，可以避免对应的伸缩架41所铰接的滑块432产生回滑现象，从而实现对滑块432的锁定。
上述每个驱动模块42驱动第一储物部3升起或下降的方式有多种，例如直接驱动 第一储物部3升起或下降，或间接驱动第一储物部3升起或下降，具体可以根据实际需要自行选择，本公开的一些实施例对此不做限定。
在一些实施例中，每个驱动模块42直接驱动第一储物部3升起或下降。
请参阅图12～13和图15，每个驱动模块42与抽屉底座2以及第一储物部3铰接，且配置为驱动第一储物部3升起或下降。
示例性的，每个驱动模块42中的驱动部421与抽屉底座2铰接，输出部422与第一储物部3铰接。这样在每个驱动模块42的驱动部421驱动输出部422自驱动部421伸出或缩回的过程中，同时使驱动部421绕其与抽屉底座2铰接的位置旋转，使输出部422绕其与第一储物部3铰接的位置旋转，进而使对应的伸缩架41展开或收拢，带动第一储物部3上升或下降。
在另一些实施例中，每个驱动模块42间接驱动第一储物部3升起或下降，也即每个驱动模块42通过驱动对应的伸缩架41的展开或收拢，带动第一储物部3的升起或下降。此时，每个驱动模块42的设置位置及其提供驱动的方式与滑动机构43的结构相关。
需要说明的是，如图5所示，以下为了便于描述，将靠近第一储物部3的铰杆组件411中第一铰杆4111的靠近第一储物部3的一端指向第二铰杆4112的靠近第一储物部3的一端的方向，以及，靠近抽屉底座2的铰杆组件411中第二铰杆4112的靠近抽屉底座2的一端指向第一铰杆4111的靠近抽屉底座2的一端的方向，称作第一方向，与之相反的方向称作第二方向。
在一些示例中，滑动结构43包括滑槽431而不包括滑块432，每个驱动模块42对应一个伸缩架41。
示例性的，请参阅图11，每个驱动模块42的驱动部421与对应的抽屉底座2连接，输出部422与对应的第二铰杆4112的靠近抽屉底座2的一端铰接，也即每个驱动模块42设置在对应的抽屉底座2上。
每个驱动模块42驱动对应的伸缩架41的驱动方式如下：
在每个驱动模块42的驱动部421驱动输出部422伸出的情况下，输出部422带动对应的第二铰杆4112的靠近抽屉底座2的一端沿第一方向滑动，进而使该第二铰杆4112与同组铰杆组件411中的第一铰杆4111发生相对转动，从而实现伸缩架41的展开，以使第一储物部3升起。在每个驱动模块42的驱动部421驱动输出部422缩回的情况下，输出部422带动对应的第二铰杆4112的靠近抽屉底座2的一端沿第二方向滑动，进而使该第二铰杆4112与同组铰杆组件411中的第一铰杆4111发生相对转动，从而实现伸缩架41的收拢，进而使第一储物部3下降。
示例性的，每个驱动模块42的驱动部421与对应的第一储物部3连接，输出部422与对应的第一铰杆4111的靠近第一储物部5的一端铰接，也即每个驱动模块42设置在对应的第一储物部3上。本示例中每个驱动模块42的驱动方式与上述示例中每个驱动模块42的驱动方式相似，此处不做赘述。
如此，在第一储物部3上升或下降的过程中，每个驱动模块42的驱动部421的位置可以保持不变，也即避免每个驱动模块42随对应的第一储物部3的上升或下降而移动，进而能够避免与驱动模块42连接的电源线反复弯曲造成折损。
在另一些示例中，请参阅图19，滑动结构43包括滑槽431而不包括滑块432，且升降机4包括至少两个伸缩架41和至少一根同步推杆45。此处，每个驱动模块42对应一根同步推杆45，也即对应两个伸缩架41。每个驱动模块42的设置位置与同步推杆45的设置位置相关。

每个驱动模块42驱动对应的伸缩架41的驱动方式如下：
在每个驱动模块42的驱动部421驱动输出部422伸出的情况下，输出部422带动对应的同步推杆45沿第一方向移动，进而带动与该同步推杆45对应的第二铰杆4112沿第一方向滑动，并使该第二铰杆4112与对应的第一铰杆4111发生相对转动，从而实现对应伸缩架41的同时展开，以使第一储物部3升起。在每个驱动模块42的驱动部421驱动输出部422缩回的情况下，输出部422会带动对应的同步推杆45沿第二方向移动，进而带动与该同步推杆45对应的第二铰杆4112向沿第二方向滑动，使该第二铰杆4112与对应的第一铰杆4111发生相对转动，从而实现对应伸缩架41的同时收拢，以使第一储物部3下降。
示例性的，每根同步推杆45设置在相邻两个伸缩架41中靠近第一储物部3的两个铰杆组件411之间，则，每个驱动模块42的驱动部421与第一储物部3连接，输出部422与对应的同步推杆45连接。本示例中每个驱动模块42的驱动方式与上述示例中每个驱动模块42的驱动方式相似，此处不做赘述。

示例性的，请参阅图11，滑动机构43设置于抽屉底座2和第二铰杆4112之间，则，每个驱动模块42中的驱动部421与抽屉底座2连接，输出部422与对应的滑块432铰接。
每个驱动模块42驱动对应的伸缩架41的驱动方式如下：
在每个驱动模块42的驱动部421驱动输出部422伸出的情况下，输出部422带动对应的滑块432沿第一方向滑动，进而使该第二铰杆4112与同组铰杆组件411中的第一铰杆4111发生相对转动，从而实现伸缩架41的展开，以使第一储物部3升起。在每个驱动模块42的驱动部421驱动输出部422缩回的情况下，输出部422带动对应的滑块432沿第二方向滑动，进而使该第二铰杆4112与同组铰杆组件411中的第一铰杆4111发生相对转动，从而实现伸缩架41的收拢，进而使第一储物部3下降。
示例性的，滑动机构43设置于第一储物部3和第一铰杆4111之间，则，每个驱动模块42中的驱动部421与第一储物部3连接，输出部422与对应的滑块432铰接。本示例中每个驱动模块42的驱动方式与上述示例中每个驱动模块42的驱动方式相似，此处不做赘述。
