背景技术
随着社会的发展，生活品质的逐步提高，人们对冰箱的美观性需求也日益突出。将冰箱嵌入橱柜，即形成嵌入式冰箱以实现装修风格统一化的家装方式已趋于流行。
将冰箱嵌入橱柜内需要避免门体在转动过程中干涉到冰箱的箱体以及橱柜，并且用户也更期望冰箱与橱柜的间隙更小，从而可以使得整体家居的美观度更高。
单轴铰链装置由于结构简单且成本较低被广泛应用于冰箱中，然而，将冰箱嵌入橱柜后，单轴铰链装置由于无法变轴心导致冰箱门体在打开至90°后会出现门体朝向箱体内移动的现象，这导致箱体内的抽屉被抽出时会被门体阻挡，从而需要设计更小的抽屉才可以避免门体在打开至90°后阻挡抽屉被抽出。

具体实施方式
以下将结合附图所示的各实施方式对本发明进行详细描述，请参照图1-图11所示，为本发明的较佳实施方式，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。但应当说明的是，这些实施方式并非对本发明的限制， 本领域普通技术人员根据这些实施方式所作的功能、方法、或者结构上的等效变换或替代，均属于本发明的保护范围之内。
本发明内所描述的表达位置与方向的词，以制冷装置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。
请参图1所示，本发明提供一种铰链机构及具有该铰链机构的制冷装置100，所述制冷装置100包括箱体1、门体2、将所述门体2转动连接至所述箱体1上的所述铰链机构。
当然，可以理解的是，本发明中的铰链机构并不限于应用于制冷装置100，也可以应用于橱柜6等。
所述门体2包括前壁21、铰链安装侧22和枢转端23。本发明中，以所述制冷装置100为嵌入式制冷装置为例进行具体阐述。所述门体2的前壁21为所述制冷装置100在嵌入橱柜6时面向外部环境的一侧。该门体2的铰链安装侧22为门体2的上侧，即所述铰链机构的一端是安装在该铰链安装侧22上的，所述铰链机构的另一端安装在所述箱体1上。该门体2的枢转端23为门体2绕箱体1转动的一端。其中，仅示出位于枢转端23一侧的橱柜6。实际安装中，所述制冷装置100是整个嵌入橱柜6中的。可以理解的是，制冷装置100不一定是嵌入橱柜6内，也可以是嵌入墙体内。
所述铰链机构包括固定于箱体1上的固定座3、固定于门体2上的活动座、用于驱动所述活动座平移的驱动组件。可知的是，开关门体2的过程中，所述门体2与所述活动座同步运动，故，所述门体2的运动轨迹与所述活动座的运动轨迹相同，以下，为了描述简便清楚，以所述门体2的运动轨迹为例进行具体阐述。
所述固定座3与所述活动座中的一个上设有铰链轴31、另一个上设有与所述铰链轴31相配合的轴槽24，所述驱动组件与所述轴槽24同侧，以作用于所述铰链轴31，使所述铰链轴31相对所述轴槽24移动，从而带动门体2平移，使所述门体2按预设轨迹移动，使所述制冷装置100能够适用于多个场景，如嵌入式场景，增强所述制冷装置100的通用性。
下面以所述铰链轴31设于所述固定座3上，所述轴槽24设于所述活动座上为例进行具体阐述，可以理解的是，在开关门体2过程中，所述铰链轴31位置不变，所述轴槽24跟随所述门体2移动，从而，所述轴槽24相对所述铰链轴31移动，以使所述铰链轴31在所述轴槽24内移动，带动所述门体2平移。当然，并不以此为限，于其 他实施方式中，所述铰链轴31也可以设置于所述活动座上，此时，所述轴槽24设于所述固定座3上。
于本实施方式中，所述活动座上仅设置所述轴槽24，所述驱动组件直接安装于所述门体2内，即，门体2上设有与所述轴槽24相连通的安装腔，驱动组件安装于安装腔内并与所述铰链轴31相连接。当然，并不以此为限，于其他实施方式中，所述驱动组件也可以直接固定于所述活动座上。
进一步地，结合图8-图11所示，所述轴槽24包括与所述铰链轴31相配合的第一轴槽241，所述第一轴槽241包括相对的第一端2411、第二端2412，在所述门体2转动至最大预设角度时，所述铰链轴31位于所述第一端2411。在所述门体2转动至最大预设角度后，所述驱动组件驱动所述铰链轴31相对所述第一轴槽241向所述第二端2412移动以带动所述门体2平移，即，在所述门体2转动至最大角度后，所述驱动组件驱动门体2单独做平移运动，能够根据用户的需求，控制门体2的平移方向以及距离，控制简单。
于一具体实施方式中，所述最大预设角度大于90°，所述门体2的运动轨迹设置为：在所述门体2(活动座)相对所述箱体1(固定座3)转动至最大预设角度后，所述驱动组件驱动所述铰链轴31相对所述第一轴槽241移动以带动所述活动座沿所述活动座的长度方向远离所述固定座3，即，带动所述门体2沿所述门体2的长度方向远离所述箱体1。一方面，所述门体2与所述橱柜6之间不会产生干涉，同时，又能够避免门体2遮蔽箱体1内的储物间室或者箱体1内的抽屉等受门体2干涉而无法打开，便于用户取放物品。当然，并不以此为限，于其他实施方式中，可以根据用户的具体需求控制门体2打开至最大角度后的平移方向以及距离。
具体地，在所述轴槽24设于所述活动座上的实施方式中，所述第一轴槽241沿所述活动座的长度方向延伸，即，所述第一轴槽241沿所述门体2水平的长度方向延伸，且，所述第一端2411位于所述第二端2412远离所述门体2的枢转端23的一侧。在所述门体2打开至最大预设角度时，此时，所述第一端2411位于所述第二端2412的前侧，所述铰链轴31位于所述第一端2411；在所述驱动组件驱动第一轴槽241相对所述铰链轴31移动，使所述铰链轴31向第二端2412移动时，所述门体2沿其长度方向向远离所述箱体1的方向移动，以减少所述门体2对所述箱体1内的储物间室的遮蔽，从而便于用户取放物品。
于一具体实施方式中，所述驱动组件包括驱动所述铰链轴31与所述第一轴槽241相对移动的电磁驱动组件4，即，通过所述电磁驱动组件4实现所述铰链轴31与所述第一轴槽241之间的相对移动。当然，并不以此为限。
结合图3所示，所述电磁驱动组件4包括相对所述第一轴槽241固定设置的电磁铁41、活动连接于所述电磁铁41上的磁芯42、与所述磁芯42相连接的限位板43，所 述限位板43与所述铰链轴31相连接，在所述门体2打开至最大预设角度后，所述限位板43限制所述铰链轴31相对所述限位板43移动，即，所述铰链轴31与所述限位板43相对静止。在所述电磁铁41处于通电状态时，所述磁芯42与所述电磁铁41相吸，因所述铰链轴31无法移动，故，使与所述电磁铁41相固定的所述门体2相对移动，使所述铰链轴31与所述第一轴槽241相对移动，带动所述铰链轴31相对所述第一轴槽241向第二端2412移动，驱动所述门体2平移。
具体地，本实施方式中，所述轴槽24设于所述门体2上，所述电磁驱动组件4固定于所述门体2上，其中，所述电磁铁41固定于所述门体2上，从而，实现所述电磁铁41相对所述第一轴槽241固定设置。
进一步地，所述电磁铁41具有与所述磁芯42相配合的导槽411，所述磁芯42活动连接于所述导槽411内，能够限制所述磁芯42与所述电磁铁41的相对移动方向，增强所述磁性驱动组件的稳定性，增强所述门体2平移的稳定性。
于一具体实施方式中，所述磁性驱动组件还包括设于所述导槽411内的弹性件44，所述磁芯42连接于所述弹性件44上。在所述门体2打开至最大预设角度且门体2平移至所述铰链轴31位于所述第二端2412后，此时，所述弹性件44处于压缩状态，且用户取放物品完毕后，控制所述电磁铁41断电，使所述电磁铁41处于断电状态，此时，在所述弹性件44的弹性回复力的作用下，所述铰链轴31相对所述第一轴槽241自所述第二端2412复位至所述第一端2411，使所述门体2能够正常关闭。当然，并不以此为限，于其他实施方式中，也可以不设置所述弹性件44，通过控制所述电磁铁41与磁芯42之间的相斥与相吸来控制所述铰链轴31的移动轨迹，即，控制所述电磁铁41与所述磁芯42相斥，以驱动位于第二端2412的所述铰链轴31向第一端2411移动。
所述弹性件44可以是弹簧，结构简单，且稳定性较好。当然，并不以此为限。
进一步地，结合图1、图2、图4-图7所示，所述轴槽24还包括于所述第一端2411与所述第一轴槽241相连通的第二轴槽242，在所述门体2处于关闭状态时，所述铰链轴31位于所述第一端2411，在所述门体2自关闭状态打开至所述最大预设角度的过程中，所述铰链轴31相对所述第二轴槽242移动，以带动所述门体2平移，能够防止门体2开关过程中，与所述橱柜6之间产生干涉。
具体地，结合图2、图5、图7、图9所示，所述限位板43上与所述第二轴槽242相对应的位置处具有限位槽431，所述限位槽431的位置以及形状均与所述第二轴槽242相同，所述铰链轴31位于所述限位槽431内。在所述门体2自关闭状态打开至所述最大预设角度的过程中，所述铰链轴31相对所述第二轴槽242移动同时相对所述限位槽431移动，即，在门体2自关闭状态打开至最大预设角度的过程中，所述限位槽431给所述铰链轴31让位，以避免所述限位板43与所述铰链轴31之间干涉，影响所述门体2的开闭。
定义处于关门状态的所述门体2的中心朝向所述门体2的枢转端23的方向为第一方向，定义与所述第一方向相反的方向为第二方向。
具体地，当所述制冷装置100的右侧设置所述铰链机构时，所述第一方向即为从左向右的方向，所述第二方向即为从右向左的方向。当所述制冷装置100的左侧设置所述铰链机构时，所述第一方向即为从右向左的方向，所述第二方向即为从左向右的方向。
所述第二轴槽242具有与所述第一端2411相对的第三端2421，在所述门体2自关闭状态打开至最大预设角度的过程中，所述铰链轴31相对所述第二轴槽242在所述第一端2411与第三端2421之间切换，以带动门体2平移。
所述固定座3与所述活动座中的一个上设有凸轮结构25、另一个上设有与所述凸轮结构25的轮廓曲线相配合的引导件32。所述轮廓曲线包括起始端、终端、位于所述起始端与终端之间的第一段251，在所述门体2处于关闭状态时，所述引导件32位于所述起始端；在所述门体2自关闭状态转动打开的过程中，所述引导件32沿所述第一段251向终端移动，带动所述铰链轴31相对所述第二轴槽242自第一端2411向第三端2421移动。
结合图4、图6所示，所述第一段251设置为在所述门体2打开至第一预设角度时，所述引导件32沿所述第一段251朝向所述第一段251靠近所述终端的一端移动，使所述铰链轴31自所述第一端2411向所述第三端2421移动，直至所述门体2打开至第二预设角度，此时，所述铰链轴31移动至所述第三端2421。所述第二预设角度大于所述第一预设角度。
具体地，所述第一段251呈弧形，且沿所述起始端向终端的方向，所述第一段251逐渐远离所述第二轴槽242，从而，在所述引导件32沿所述第一段251向终端移动时能够带动所述铰链轴31向第三端2421移动。
于一具体实施方式中，所述轴槽24设置于所述活动座上，所述第二轴槽242沿所述门体2的厚度方向延伸，且所述第一端2411位于所述第二轴槽242中与所述第一端2411相对的第三端2421远离所述固定座3的一侧，即，所述第一端2411位于所述第三端2421的前侧。在门体2的打开角度位于0°-90°之间时，所述第二轴槽242的延伸方向与所述第一方向之间的夹角逐渐减小，从而，在所述门体2的打开角度介于0°-90°之间时，所述门体2平移使所述铰链轴31自第一端2411移动至第三端2421时，所述门体2在朝向所述第一方向移动的同时朝远离所述箱体1的方向移动。一方面，使所述门体2沿第一方向远离所述箱体1，可使得所述门体2尽量朝第一方向远离箱体1，保证所述门体2的开度，便于用户取放物品；另一方面，所述门体2朝远离所述箱体1的方向移动，增大所述门体2与箱体1之间的距离，能够防止门体2打开过程中，所述门体2的后壁与箱体1之间干涉，同时，对于嵌入式制冷装置100而言，能够使 所述门体2的前壁21位于所述枢转端23的一端向前突伸出所述橱柜6的前端，能够减少门体2转动过程中所述门体2与所述橱柜6之间的干涉。当然，并不以此为限，可以理解的是，可以根据具体需求调节所述第二轴槽242的延伸方向以控制门体2的平移方向。
具体地，于一具体实施方式中，所述第二预设角度为90°。当然，并不以此为限。
进一步地，本发明中，在所述门体2自关闭状态打开至最大预设角度的过程中，所述门体2的运动轨迹设置为：在所述门体2自关闭状态打开至第一预设角度时，所述门体2原地转动；在所述门体2打开至第一预设角度且继续旋转打开时，所述引导件32沿所述第一段251朝向所述第一段251靠近所述终端的一端移动，使所述铰链轴31沿所述第二轴槽242自所述第一端2411向所述第三段253移动，使所述门体2向第一方向同时向远离所述箱体1的方向移动；在所述门体2打开至所述第二预设角度并继续打开至最大预设角度的过程中，所述铰链轴31自所述第三端2421向所述第一端2411复位移动，使所述门体2向所述第二方向移动，以进一步增大所述门体2的开度，便于用户取放物品。当然，并不以此为限。
可知的是，在门体2处于关闭状态时，门体2上的门封紧密吸附于箱体1上，从而，在门体2自关闭状态打开时，先使门体2原地转动第一预设角度，能够使所述门封先脱离所述箱体1，以防门封发生变形损坏，影响门体2后续的密封性能。对应的，在关门至最后阶段，门体2原地转动至关闭，同样能够减少门封的变形，有利于门体2的顺利关闭。
同时，对于具有翻转梁的制冷装置100，门体2自关闭状态打开时先原地转动，能够使翻转梁翻转并脱离箱体1上的导向结构，使后续门体2能够继续旋转打开。对应的，在关门至最后阶段，门体2原地转动至关闭的过程中，能够使翻转梁在箱体1上的导向结构的引导下翻转至遮蔽左右门体2之间的缝隙。
于一具体实施方式中，所述第一预设角度介于30°-60°之间。当然，并不以此为限。
进一步地，所述驱动组件还包括与所述铰链轴31相连接的弹性驱动组件5，所述弹性驱动组件5用于在所述门体2自关闭状态打开至所述第一预设角度时限制所述铰链轴31沿所述第二轴槽242移动，即，使所述铰链轴31保持在所述第一端2411，从而，使所述门体2原地转动。同时，在所述门体2自第二预设角度继续转动时，所述弹性驱动组件5驱动所述铰链轴31自所述第三端2421向所述第一端2411移动，以使所述门体2转动的同时向所述第二方向平移。另，在所述门体2打开至最大预设角度后，所述弹性驱动组件5用以限制所述铰链轴31沿所述第二轴槽242移动，从而，使所述铰链轴31能够在所述电磁驱动组件4的作用下沿所述第一轴槽241向所述第二端2412移动。
于一具体实施方式中，所述弹性驱动组件5包括与所述轴槽24相对固定设置的安装座51、与所述铰链轴31相连接的滑块52、连接所述安装座51与所述滑块52的弹簧53。在所述门体2自关闭状态转动至所述第一预设角度的过程中，所述弹簧53使所述铰链轴31保持在所述第一端2411。在所述门体2自第一预设角度旋转打开至第二预设角度的过程中，所述铰链轴31向第三端2421移动，所述弹簧53处于压缩状态。在所述门体2自第二预设角度继续打开至所述最大预设角度的过程中，在所述弹簧53的弹性回复力的作用下，驱动所述铰链轴31自第三端2421向所述第一端2411移动复位。当然，并不以此为限。
具体地，在所述轴槽24设置于所述门体2上时，所述弹性驱动组件5中的安装座51固定于所述门体2上，以使所述安装座51与所述轴槽24相对固定设置。且使所述弹性驱动组件5能够作用于所述铰链轴31，使所述弹性驱动组件5对所述铰链轴31的限位作用不受开关门体2的影响。
进一步地，结合图9、图11所示，所述滑块52上与所述第一轴槽241相对应的位置处具有滑槽521，所述铰链轴31位于所述滑槽521内，所述滑槽521的位置以及尺寸与所述第一轴槽241相对应。在所述活动座打开至最大预设角度后，所述铰链轴31相对所述第一轴槽241移动同时相对所述滑槽521移动。从而，在门体2打开至最大预设角度后平移的过程中，所述滑槽521给所述铰链轴31让位，以避免所述滑块52与所述铰链轴31之间干涉，影响所述门体2的平移。
进一步地，结合图1、图4所示，所述轮廓曲线还具有连通所述起始端与所述第一段251的第二段252，所述第二段252为以所述第一端2411为圆心的圆弧。在所述门体2由关闭状态打开至第一预设角度的过程中，所述引导件32以所述铰链轴31为圆心并沿所述第二段252移动，此时，在所述弹性驱动组件5的协同作用下，所述铰链轴31保持在所述第一端2411，从而使所述门体2能够原地转动预设角度。
可以理解的是，所述第二段252的长度可根据所述门体2需要原地转动的角度来确定。同时，通过设置与所述引导件32相配合的第二段252，能够进一步限位所述铰链轴31，使所述门体2打开至所述第一预设角度的过程中，所述铰链轴31保持在所述第一端2411。
进一步地，结合图6、图8所示，所述轮廓曲线还具有连通所述第一段251与所述终端的第三段253，沿所述起始端向终端的方向，所述第三段253逐渐靠近所述第二轴槽242。在所述门体2打开至所述第二预设角度并继续打开时，所述引导件32抵持于所述第三段253并朝向所述终端移动，在所述弹性驱动组件5的协同作用下，带动所述铰链轴31自第三端2421向第一端2411移动，所述门体2朝向与所述第一方向相反的第二方向移动。
可以理解的是，通过设置所述第三段253，从而，在所述弹性驱动组件5驱动所述 铰链轴31相对所述第二轴槽242向第一端2411移动时，能够使所述铰链轴31缓慢向第一端2411移动，增强所述门体2平移的平稳性，且降低噪音，防止铰链轴31与第二轴槽242的孔壁碰撞导致损坏。
进一步地，所述门体2上与所述凸轮结构25的轮廓曲线相对应的位置处凹设有让位槽26，所述让位槽26的形状与所述轮廓曲线相同。所述引导件32延伸至所述让位槽26内。一方面，在安装所述门体2时，需要调节所述门体2的高度，若门体2高度调节过大，易导致所述引导件32与所述凸轮结构25相脱离，从而，能够保证所述引导件32始终与所述凸轮结构25相配合，保证门体2上下调节时所述引导件32以及凸轮结构25的配合结构的可靠性；另一方面，所述引导件32与所述让位槽26配合也能够使所述引导件32始终保持于所述凸轮结构25的轮廓曲线上，增强所述门体2平移的稳定性。
可以理解的是，在具有所述让位槽26以及所述引导件32的实施方式中，所述让位槽26具有避让段261，在所述门体2转动至最大预设角度后平移时，所述引导件32于所述避让段261内移动，以使所述门体2能够平移。
综上所述，本发明中的铰链机构，在活动座相对于固定座3打开至最大预设角度后，通过驱动组件驱动活动座平移，即，在所述门体2转动至最大角度后，所述驱动组件驱动门体2单独做平移运动，能够根据用户的需求，控制门体2的平移方向以及距离，控制简单。
