后框架140可包括后边框和两个横向侧边框。后框架140的各个边框可均具有自其底部边缘延水平方向向内延伸的底沿。后搁物板120搭放于后框架140的底沿上。后框架140还可具有分别自其横向两侧底沿的内侧边缘向下延伸的固定架141。左右两个固定架141均具有自其中部水平向外延伸的支撑部，用于安装搁物架100。第一铰接点和第三铰接点可设置于后框架140的固定架141上并设置于支撑部的上方。前框架130和后框架140可采用PA、PPS等工程塑料制成。
在本发明的优选实施例中，连杆机构150的数量可为两个，以使前搁物板110的高度调节更加稳定，避免卡顿现象的发生，并提高了前搁物板110的承重能力。两个连杆机构150可对称地设置于前搁物板110和后搁物板120的横向两侧。具体地，其中一个连杆机构150可配置为连接前框架130的左侧边框和后框架140的左侧固定架141。另一个连杆机构150可配置为连接前框架130的右侧边框和后框架140的右侧固定架141。
在一些实施例中，后搁物架100还可设置有至少一个沿进深方向和纵向方向延伸的扇形面板142，以调节连杆机构150的摆动角度。具体地，扇形面板142可设置为自后框架140的支撑部的外侧边缘垂直于该支撑部向上延伸。第一铰接点可设置于扇形面板142的扇形圆心处。扇形面板142具有多个沿圆周分布，并沿横向方向贯穿扇形面板142的定位孔。在本 发明中，定位孔的数量可为两个、三个或三个以上等。在图示实施例中，在后搁物架100的左右两侧均可设置有扇形面板142。每个扇形面板142上均设置有三个沿圆周分布的定位孔。
在一些实施例中，第一摆杆151可设置有一定位装置170。该定位装置170可设置为与扇形面板142上的定位孔配合，以将连杆机构150固定于定位孔对应的角度(定位孔的中心相对于扇形面板142的圆心的角度)。
图2是根据本发明一个实施例的搁物架100的前搁物板110处于第二状态的示意性结构图；图3是根据本发明一个实施例的搁物架100的前搁物板110处于第三状态的示意性结构图。在图示实施例中，两个连杆机构150可配置为允许前搁物板110在第一状态、第二状态和第三状态之间切换。参见图1，当前搁物板110和后搁物板120处于第一状态时，前搁物板110与后搁物板120在水平方向上平齐。参见图2，当前搁物板110和后搁物板120处于第二状态时，前搁物板110高于后搁物板120，且第一铰接点在纵向方向上的投影位于第二铰接点在纵向方向上的投影的前侧。参见图3，当前搁物板110和后搁物板120处于第三状态时，前搁物板110与后搁物板120的相对位移值为最大值，且第一铰接点与第二铰接点在纵向方向上的投影重合。用户可根据实际使用需求调节前搁物板110的状态，使冰箱200的储物空间灵活可调。
图4是图1所示搁物架100的示意性俯视图；图5是图4中区域A的示意性局部放大图。参见图4和图5，定位装置170可包括定位销171、拉线172、弹簧173和限位销174。具体地，定位销171的始端设置为穿入扇形面板142的定位孔，以将连杆机构150固定于定位孔对应的角度。定位销171的末端设置为与拉线172固定连接，并穿过第一摆杆151，以使定位销171的始端脱离定位孔。拉线172可采用钢丝绳等柔性较好、不伸缩变形的线索。弹簧173的一端设置为与第一摆杆151的外表面(平行于扇形面板142并邻近于扇形面板142的表面)固定连接，另一端设置为与定位销171的末端端面固定连接，以使定位销171自动地穿入定位孔。限位销174设置为沿定位销171的径向方向穿过定位销171，以防止定位销171沿其轴向方向向外运动穿出扇形面板142。定位装置170还可包括一外壳175，其固定于第一摆杆151的外表面，且限位销174和弹簧173设置于外壳175内。外壳175具有一沿横向方向贯穿的通孔，定位销171设置为穿过该通孔。
在一些实施例中，定位销171的始端端面可为斜面。当前搁物板110与后搁物板120之间的距离增加时，使定位销171自动地脱离定位孔。例如，当前搁物板110从第一状态切换至第二状态时，无需拉动拉线172，即可使定位销171的始端脱离定位孔。在该实施例中， 为保证定位销171的始端端面始终垂直于第一摆杆151的运动方向，定位销171上还开设有凹槽。对应地，外壳175的通孔的内表面具有沿径向方向向内延伸的键，其配置为与定位销171上的凹槽配合，以防止定位销171旋转。
在一些实施例中，搁物架100还可包括一调节装置160。调节装置160可设置于前搁物板110的下方，用于拉动拉线172，以使定位销171的始端脱离扇形面板142的定位孔。在一些优选实施例中，调节装置160设置于前框架130的前边框下方，以便于调节。调节装置160可配置为允许定位装置170的定位销171在锁紧状态和可调状态之间切换(当定位销171处于锁紧状态时，定位销171穿入定位孔，前搁物板110相对于后搁物板120的高度不可调节；当定位销171处于可调状态时，定位销171未穿入定位孔，前搁物板110相对于后搁物板120的高度可以调节)。
图6是图1所示搁物架100的示意性仰视图；图7是图6中区域B的示意性局部放大图。参见图6和图7，调节装置160可包括限位件161和滑动件162。具体地，限位件161具有一个底板和在各自底端与底板结合且两两相对的四个侧板。且限位件161设置于前搁物板110的下方，以与前搁物板110形成一腔体。滑动件162可滑动地设置于腔体内。滑动件162设置为与拉线172的另一端固定连接，以拉动拉线172，进而使定位销171的始端脱离定位孔。限位件161的底板可设置有沿水平方向延伸的滑槽1611。相应地，滑动件162具有与滑槽1611相对应的延伸部1621，其设置为可受控地沿滑槽1611滑动，以调节定位销171的工作状态(锁紧状态和可调状态)。
在一些实施例中，拉线172的外部可设置有一罩壳163，可为拉线172的拉动方向起导向作用，并可提高搁物架100的美观性。罩壳163可由数段中心线为直线的圆管，通过接头拼接而成，且各段圆管可绕接头转动。圆管与接头可通过键连接、卡接等连接方式连接。罩壳163的一端设置为通过接头与第一摆杆151的内表面固定连接，另一端设置为与调节装置160的限位件161的侧板固定连接。罩壳163的部分圆管设置为可随第一摆杆151的摆动绕第一铰接点摆动，使罩壳163隐藏于第一摆杆151的后侧，使搁物架100整体简洁美观。
基于前述任一实施例的搁物架100，本发明还可提供一种冰箱200。图8是根据本发明一个实施例的冰箱200的示意性结构图。参见图8，冰箱200可包括限定有储物间室211的箱体210和用于开闭储物间室211的取放口的门体(图中未示出)。搁物架100可拆卸地设置于箱体210的内胆壁上。冰箱200的内胆壁上可设置有胆筋，搁物架100可通过后框架140的支撑部搭放于胆筋上。
