为了使本领域的技术人员更好地理解本发明中的技术方案，下面将结合本发明实施方式中的附图1-6，对本发明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是本发明一部分实施方式，而不是全部的实施方式。基于本发明中的实施方式，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，都应当属于本发明保护的范围。
本发明内所描述的表达位置与方向的词，以冰箱正常使用时门体所在的一侧为“前”。本发明中的术语第一、第二、第三、第四等仅用于描述目的，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；此外，需要说明的是，除非另有明确的规定和限定，术语“连接”应作广义理解，例如，连接可以是直接连接或者通过中间媒介间接连接，可以是固定连接也可以是活动连接或者可拆卸连接或者一体式连接。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本发明的各个图示中，为了便于图示，结构或部分的某些尺寸会相对于其它结构部分夸大，因此，仅用于图示本发明主题的基本结构。
请参图1-图4所示，本发明提供一种铰链机构3、具有该铰链机构3的制冷设备10，所述制冷设备10嵌入橱柜20内。图1示出了根据本发明一个实施方式中的嵌入式制冷设备10的部分示意性立体图，其中仅示出一侧的橱柜20，实际安装中，嵌入式制冷设备10是整个嵌入橱柜20中的。可以理解的是，嵌入式制冷设备10不一定是嵌入橱柜20内，也可以是嵌入墙体内。
请参图1所示，所述制冷设备10包括箱体1、用以打开或关闭所述箱体1的门体2，所 述铰链机构3用以将所述门体2转动连接至所述箱体1上。
需要强调的是，本发明中的所述铰链机构3不仅适用于所述制冷设备10，也可适用于其他场景，例如橱柜20、酒柜、衣柜、微波炉等其他家电。
请参图1-图4所示，包括本发明第一实施方式中的铰链机构3，所述铰链机构3包括固定于箱体1上的固定座31、固定于门体2上的活动座32、将所述活动座32转动连接于所述固定座31上的联动组件33，所述活动座32具有相较所述固定座31闭合的关闭状态、相较所述固定座31枢转打开的打开状态。在所述活动座32处于关闭状态时，所述门体2处于关闭状态，在所述活动座32处于打开状态时，所述门体2处于打开状态。

定义处于关闭状态的所述活动座32的中心背离所述铰链机构3的枢转侧的方向为第一方向。
可以理解的是，上述的铰链机构3的枢转侧即指所述制冷设备10的枢转侧，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，所述第一方向为向右。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，所述第一方向为向左。本实施方式中，以所述铰链机构3安装于所述箱体1的右端为例进行详细阐述。
进一步地，本实施方式中，在所述活动座32自关闭状态打开至最大角度的过程中，所述联动组件33设置为带动所述活动座32向第一方向同时向远离所述固定座31的方向移动，即，在所述铰链机构3安装于所述箱体1的右端的实施方式中，所述预设轨迹为：在所述门体2自关闭状态打开至最大角度的过程中，所述门体2同时向前以及向左移动，增大所述门体2与所述橱柜20之间的距离，避免开门过程中门体2与橱柜20之间产生碰撞干涉，且能够增大所述嵌入式制冷设备10的最大开门角度，使所述门体2的最大打开角度大于90°，便于用户取放物品。
于一具体实施方式中，所述最大角度为116°，当然，并不以此为限，于其他实施方式中，所述最大角度可根据具体场景进行设置，如大于116°均可，只要在所述门体2打开至所述最大角度时，不会与所述橱柜20之间产生干涉即可。
进一步地，所述联动组件33设置为在所述活动座32打开至90°时，使所述箱体1位于所述枢转侧的侧壁所在的平面与所述门体2的前壁之间的间隙不小于0，即，在所述门体2打开至90°时，所述门体2的前壁不会突出所述枢转侧的侧壁，能够防止所述门体2与所述 橱柜20之间产生干涉，同时，使所述门体2能够进一步打开至所述最大角度，便于用户取放物品。
具体地，所述固定座31上具有靠近所述铰链机构3的枢转侧的第一枢转点311、位于所述第一枢转点311远离所述枢转侧的一侧的第三枢转点312；所述活动座32上具有靠近所述枢转侧的第二枢转点321、位于所述第二枢转点321远离所述枢转侧的一侧的第四枢转点322。
进一步地，在所述活动座32处于关闭状态时，所述第二枢转点321以及所述第四枢转点322均位于所述第一枢转点311靠近所述枢转侧的一侧，即，在所述铰链机构3安装于所述箱体1的右端的实施方式中，所述第二枢转点321以及所述第四枢转点322均位于所述第一枢转点311的右前侧。所述联动组件33包括第一连杆331、第二连杆332，所述第一连杆331的两端分别转动连接于所述第一枢转点311、第二枢转点321，所述第二连杆332的两端分别转动连接于所述第三枢转点312、第四枢转点322，且在所述门体2开关过程中，所述第一连杆331与所述第二连杆332之间无交错。通过控制所述第一枢转点311至第四枢转点322的位置以及第一连杆331、第二连杆332的长度来使所述活动座32能够按上述的预设轨迹移动，从而带动所述门体2按上述的预设轨迹移动。
可以理解的是，所述固定座31、活动座32、第一连杆331、第二连杆332形成四连杆结构，结构简单。本发明中，通过设置上述的四连杆结构，且将所述第二枢转点321以及所述第四枢转点322均位于所述第一枢转点311靠近所述枢转侧的一侧，使所述第二枢转点321以及第四枢转点322位于所述第一枢转点311以及第三枢转点312靠近所述枢转侧的一侧，且所述第一连杆331与所述第二连杆332之间无交错。从而，能够通过简单的四连杆结构实现所述门体2自关闭状态打开的过程中按上述的预设轨迹运动，保证开关门体2过程中，所述门体2与所述橱柜20之间无干涉，使所述门体2能够自由开门；同时，能够控制所述门体2开门过程中沿所述第一方向的内移量，能够避免内移过多遮蔽箱体1内的储物空间，影响用户取放物品。

进一步地，所述箱体1上具有安装槽，所述固定座31嵌装于所述安装槽内，减小了所述铰链机构3的外部安装空间，实现所述铰链机构3的小型化；同时，在所述制冷设备10完全无缝嵌入式装入所述橱柜20内后，能够使门体2打开过程中，所述铰链机构3与所述橱柜20之间无干涉。
进一步地，所述第一连杆331向远离所述枢转侧的方向弯折呈L型连杆以避让箱体1，从而，在开关门体2过程中，所述第一连杆331位于所述固定座31外侧的部分结构不会与所述箱体1产生干涉。
具体地，所述第一连杆331的弯折角度介于90°-120°之间。当然，并不以此为限。
进一步地，所述第一连杆331朝向所述第二连杆332的一侧具有避让所述第二连杆332的第一避让部3311，以使开关门过程中，所述第一连杆331与所述第二连杆332之间不会产生碰撞干涉，使所述门体2能够自由打开。
具体地，所述第一避让部3311自所述第一连杆331朝向所述第二连杆332的一侧向远离所述第二连杆332的方向凹设形成。当然，并不以此为限。如图2所示，在所述门体2处于关闭状态时，所述第二连杆332位于与所述第四枢转点322的一端位于所述第一避让部3311处。
进一步地，所述第二连杆332朝向所述第一连杆331的一侧具有避让所述第一连杆331的第二避让部3321，以使开关门过程中，所述第一连杆331与所述第二连杆332之间不会产生碰撞干涉，使所述门体2能够自由打开。
可以理解的是，所述第一避让部3311与所述第二避让部3321位于所述第一连杆331与所述第二连杆332之间，以实现开关门体2过程中，所述第一连杆331与所述第二连杆332之间的相互避让，同时，能够保证所述第一连杆331与所述第二连杆332的强度，保证了所述铰链机构3的稳定性，保证所述门体2移动的平稳性，防止在所述门体2的自重下，所述第一连杆331和/或所述第二连杆332弯折导致所述铰链机构3失效，同时所述门体2下垂。
于一具体实施方式中，所述第二连杆332包括自所述第三枢转点312朝向所述活动座32且向所述枢转侧延伸的第一段3322、自所述第一段3322远离所述第三枢转点312的一端向所述固定座31且向所述枢转侧延伸至所述第四枢转点322的第二段3323；所述第一段3322与所述第二段3323之间的夹角形成所述第二避让部3321。能够保证所述第二连杆332整体的强度，保证所述铰链机构3的稳定性。
具体地，所述第一段3322与所述第二段3323之间的夹角为90°-140°，如136°，当然，并不以此为限，可以根据具体情况，调整所述第一段3322与所述第二段3323之间的夹角。
请参图2所示，在所述门体2处于关闭状态时，所述第一连杆331的弯折部位于所述第二避让部3321。请参图4所示，在所述门体2打开至所述最大角度时，所述第一连杆331位于所述第二枢转点321的一端位于所述第二避让部3321，以避让所述第一连杆331。
进一步地，所述联动组件33还包括设于所述固定座31内的阻尼结构333、连接于所述第二连杆332位于所述第三枢转点312的一端且向远离所述第二连杆332的方向突伸的限位杆334，所述限位杆334与所述阻尼结构333相配合。
可以理解的是，所述限位杆334、第二连杆332位于所述第三枢转点312的相对两侧，在开门过程中，所述第二连杆332绕所述第三枢转点312转动时，能够同步带动所述限位杆334转动，所述限位杆334抵持于所述阻尼结构333，从而能够带动所述阻尼结构333作用，所述阻尼结构333反作用于所述限位杆334，以防止开门过程中，所述门体2自由旋转导致与橱柜20等发生碰撞或者门体2自由旋转导致不便于用户取放物品；同时，在关门过程中，所述阻尼结构333反作用于所述限位杆334，所述限位杆334带动所述第二连杆332转动，能够减小关门力，且防止关门不到位。
具体地，所述阻尼结构333包括固定于所述固定座31上且靠近所述第一枢转点311的第一限位块3331、连接于所述第一限位块3331且向远离所述枢转侧的方向延伸的伸缩杆3332、设于所述伸缩杆3332远离所述第一限位块3331的一端的第二限位块3333、套设于所述伸缩杆3332上的弹簧3334，所述弹簧3334的两端分别抵持于所述第一限位块3331、第二限位块3333上。所述限位杆334与所述第二限位块3333相抵持。在开门过程中，所述第二连杆332绕所述第三枢转点312转动时，能够同步带动所述限位杆334转动，所述限位杆334挤压所述阻尼结构333，使所述伸缩杆3332回缩，此时，所述弹簧3334处于压缩状态，在所述弹簧3334的弹性回复力的作用下，所述第二限位块3333与所述限位杆334处于抵持状态，且给所述限位杆334反向转动的力，以防止开门过程中，所述门体2自由旋转导致与橱柜20等发生碰撞或者门体2自由旋转导致不便于用户取放物品；同时，在关门过程 中，在所述弹簧3334的弹性回复力的作用下，所述第二限位块3333带动所述限位杆334转动，所述限位杆334带动所述第二连杆332转动，能够减小关门力，且防止关门不到位。
