2的过程中，所述门体2与所述橱柜20之间产生碰撞。
可知的是，在所述门体2旋转打开/关闭的过程中，所述活动座32与所述门体2同步运动，即，所述门体2按预设轨迹旋转打开即指所述活动座32按预设轨迹旋转打开。
定义自所述箱体1的中心远离枢转侧的一侧为第一方向，自所述箱体1的中心朝向处于关闭状态的门体2的方向为第二方向。
需要说明的是，上述的枢转侧即指所述门体2相对所述箱体1转动的一侧，也即指与铰链机构3相对应的一侧。在所述铰链机构3安装于所述箱体1的左端时，上述的枢转侧即指左侧，此时，所述第一方向为自左向右的方向；在所述铰链机构3安装于所述箱体1的右端时，上述的枢转侧即指右侧，此时，所述第一方向为自右向左的方向。在所述门体2安装于所述箱体1的前侧的实施方式中，所述第二方向即指前向。
具体地，所述连杆组件33包括第一连杆331、第二连杆332、第三连杆333、第四连杆334。所述第一连杆331与所述第二连杆332并排且相间隔设置，所述第一连杆331的相对两端分别转动连接于所述固定座31、活动座32上，所述第二连杆332的一端转动连接于所述活动座32上、另一端与所述第三连杆333相转动连接，所述第三连杆333远离所述第二连杆332的一端转动连接于所述第一连杆331上，所述第四连杆334的一端转动连接于所述固定座31上，另一端铰接于所述第二连杆332与所述第三连杆333的铰接点处。此时，所述第一连杆331、第二连杆332、第三连杆333、活动座32共同形成四边形结构。而四边形结构不稳定，从而，所述第一连杆331、第二连杆332、第三连杆333、活动座32之间能够发生相对运动，带动门体2旋转打开并平移。其中，所述第四连杆334能够进一步限定所述门体2的运动轨迹。
本发明中，结合图5-图7所示，通过所述固定座31、活动座32以及所述连杆组件33之间的配合，能够带动门体2在旋转打开的同时平移，结构简单且体积较小；同时，门体2在旋转打开的过程会沿第一方向和/或第二方向平移，即所述门体2向前平移和/或向远离位于所述枢转侧的橱柜20的方向平移，能够避免门体2与橱柜20之间产生干涉，且，能够增大门体2的开度，便于用户取放物品。结合图7所示，本发明中的所述门体2的最大开启角度能够达到135°，即，所述门体2能够在135°的范围内自由旋转打开，且不与橱柜20之间产生干涉。当然，并不以此为限，于其他实施方式中，可以根据需求的最大开启角度，适应性改变所述连杆组件33中各连杆的铰接位置以及长度等，如将最大开启角度设置为大于135°。
可知的是，门体2在旋转打开过程，可以在某一段开启角度区间内同时沿第一方向以及第二方向平移，也可以在某一段开启角度区间内仅沿第一方向平移，也可以在某一段开启角度区间内仅沿第二方向平移。可以根据门体2的预设轨迹对所述连杆组件33进行适应性设计，以使门体2在旋转打开的过程中，能够按预设轨迹平移。
进一步地，所述铰链机构3设置为使所述门体2打开至90°时，所述门体2的前壁与所述箱体1位于所述枢转侧的侧壁相平齐，使所述门体2不会影响箱体1内的搁架、抽屉等的使用，保证所述制冷设备10的容积使用率，同时，能够实现无缝嵌入式制冷设备10的正常使用。
具体地，所述第二连杆332与所述第三连杆333铰接于第一铰接点A，所述第四连杆334远离所述固定座31的一端铰接于所述第一铰接点A。
进一步地，结合图3所示，所述第二连杆332、第三连杆333、第四连杆334于所述第一铰接点A处相互贴合，增大了连杆组件33中各连杆之间的接触面积，增强了所述铰链机构3整体的稳定性以及强度。
于图3-图7所示一具体实施方式中，所述第二连杆332位于所述第一连杆331远离所述固定座31的一侧，便于各连杆的设置，且能够使所述连杆组件33整体更加紧凑，减小所述连杆组件33的体积。当然，并不以此为限，即，于其他实施方式中，所述第二连杆332也可以位于所述第一连杆331靠近所述固定座31的一侧。
进一步地，所述第一连杆331与所述活动座32转动连接于第二铰接点B，所述第一连杆331与所述固定座31转动连接于第四铰接点D，所述第三连杆333与所述第一连杆331转动连接于第三铰接点C。所述第三铰接点C位于所述第二铰接点B与所述第四铰接点D之间。在所述第二连杆332位于所述第一连杆331远离所述固定座31的一侧的实施方式中，所述第四连杆334与所述第一连杆331相交叉，且所述第四连杆334位于所述第二铰接点B与所述第三铰接点C之间。使所述连杆组件33整体更加紧凑，减小所述连杆组件33的体积。
进一步地，所述第一连杆331包括沿上下方向间隔设置的第一板3311、第二板3312，所述第四连杆334、第三连杆333均夹于所述第一板3311、第二板3312之间。使所述连杆组件33整体更加紧凑，减小所述连杆组件33的体积。
进一步地，所述第四连杆334的上表面、下表面分别与所述第一板3311、第二板3312相贴合；所述第三连杆333的上表面、下表面分别与所述第一板3311、第二板3312相贴合。增大了连杆组件33中各连杆之间的接触面积，增强了所述铰链机构3整体的
稳定性以及强度。
进一步地，结合图4所示，所述第一连杆331包括设于所述第一板3311与第二板3312之间的多个间隔设置的支撑块3315、设于所述第一板3311与第二板3312之间供所述第四连杆334穿过的第一通道3313、容纳所述第三连杆333的第二通道3314；所述第一通道3313、第二通道3314分别由相邻的两个支撑块3315以及第一板3311、第二板3312共同形成。能够增强所述第一连杆331的强度，增强了所述铰链机构3整体的稳定性以及强度。
进一步地，所述第四连杆334上具有给所述支撑块3315让位的弯曲部3341。请参图5-图7所示，在所述门体2处于关闭状态以及旋转打开过程中，所述第四连杆334与形成所述第一通道3313的支撑块3315之间无干涉，减少噪音，且使所述门体2能够顺畅地开闭。
进一步地，请参图8-图9所示，为本发明另一具体实施方式中的所述制冷设备10。该实施方式中的所述制冷设备10具有沿上下方向间隔设置的两个所述门体2、位于两个所述门体2之间的中梁101。所述铰链机构3设置于所述中梁101上，此时，所述铰链机构3为将上门的下铰链机构3与下门的上铰链机构3一体化设置形成，能够减小中梁上设置所述铰链机构3的空间，减小中梁的101厚度，增强所述制冷设备10整体的美观性，增大所述制冷设备10内部的储物容积，且降低成本。
具体地，所述固定座31包括用以固定于箱体1上的固定板311、固定于所述固定板311上的水平板312。所述铰链机构3包括分设于所述水平板312的上、下两侧的两组所述连杆组件33、分别与两组所述连杆组件33相配合的两个活动座32，两个所述活动座32分别与上、下排列的两个所述门体2相连接，从而，能够减小中梁上设置所述铰链机构3的空间，减小中梁的厚度，增强所述制冷设备10整体的美观性，增大所述制冷设备10内部的储物容积，且降低成本。
两组所述连杆组件33的结构可沿用上述的连杆组件33的结构，于此，不再赘述。
综上所述，本发明中的铰链机构3，通过所述固定座31、活动座32以及所述连杆组件33之间的配合，能够带动门体2在旋转打开的同时平移，结构简单且体积较小；同时，门体2在旋转打开的过程中的平移方向具有在第一方向以及第二方向上的分量，能够避免门体2与橱柜20之间产生干涉，且，能够增大门体2的开度，便于用户取放物品。
