具体实施方式
下面将结合附图，对本公开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。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。
在本申请的描述中，需要理解的是，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
为便于描述，如无特殊说明，本公开对于上、下、左、右、前、后的方位表述均以冰箱使用时的状态为参考。冰箱使用时面向用户的一侧为前侧，与之相反的一侧为后侧。冰箱的高度方向为上、下方向。冰箱的左右方向与用户的左右方向相反，例如冰箱的左侧为用户的右侧、冰箱的右侧为用户的左侧。
家庭生活中，冰箱的门体在打开后，经常会因重心偏移而自动关闭，无法保持在打开状态。因此，当用户从冰箱中取放食物时，需要一手扶门，一手取放食物，使用户的使用体验较差。
本公开的一些实施例提供了一种冰箱1000，如图1和图2所示，冰箱1000包括箱体1、门体2和铰链组件3。
箱体1大致呈矩形箱状，其内限定有储藏间室。所述储藏间室的一侧(如图1中所示的前侧)敞开，且被配置为储藏食物。所述储藏间室可被分隔成冷藏室和冷冻室。所述冷藏室可以将其内部空气的温度保持在约0℃至5℃之间，并以冷藏模式储藏食物。所述冷冻室可以将其内部空气的温度保持在约-30℃至0℃之间，并以冷冻模式储藏食物。此外，箱体1还可以包括其他腔室，例如，真空室、恒温室等。
例如，箱体1包括位于其上部的冷藏室和位于其下部的冷冻室，冷藏室和冷冻室例如可以沿冰箱1000的高度方向(即如图1所示的上下方向)排列。可以理解的是，冷藏室和冷冻室还可以以其他形式排布，本公开对此不做限定。
门体2通过铰链组件3连接在箱体1的一端(如前端)。门体2可以铰链组件3为轴进行旋转，从而打开或关闭所述储藏间室(如冷藏室和冷冻室)。当门体2打开时，所述储藏间室敞开的前侧可允许食物被放入或取出。
如图1所示，门体2包括第一门体201(如冷藏室门)和第二门体202(如冷冻室门)。 铰链组件3包括第一铰链组件100、第二铰链组件200、第三铰链组件300和第四铰链组件400。
第一铰链组件100设置在箱体1的上部，且分别与箱体1和第一门体201固定连接。第二铰链组件200设置在箱体1的中部，且分别与箱体1和第一门体201固定连接。第一铰链组件100与第二铰链组件200沿同一轴线设置，以使第一门体201可以绕该轴线旋转，以实现第一门体201的开合。
第三铰链组件300设置在箱体1的中部，且分别与箱体1和第二门体202固定连接。第四铰链组件400设置在箱体1的下部，且分别与箱体1和第二门体202固定连接。第三铰链组件300与第四铰链组件400沿同一轴线设置，以使第二门体202可以绕该轴线旋转，以实现第二门体202的开合。
在一些实施例中，参见图3、图5和图6，第一铰链组件100包括第一铰链板110、第一铰链轴组120和第一铰链槽组130。
第一铰链板110包括第一连接部111和与第一连接部111相连的第一延伸部112。第一连接部111连接在箱体1的上侧壁上。第一连接部111具有多个通孔1111，箱体1具有多个螺纹孔，多个所述螺纹孔位于箱体1的上侧壁中且与多个通孔1111对应，通过紧固件如螺钉可以将第一连接部111与箱体1固定连接。
第一铰链轴组120设置在第一延伸部112上，且从第一延伸部112的下表面向下延伸。第一铰链槽组130对应于第一铰链轴组120设置在第一门体201的上端。第一铰链轴组120插设在第一铰链槽组130中，且与第一铰链槽组130相配合。
这样，箱体1和第一门体201通过第一铰链组件100连接，第一门体201可通过第一铰链组件100相对于箱体1旋转。
在一些实施例中，参见图4所示，第二铰链组件200包括第二铰链板210、第二铰链轴组220和第二铰链槽组。
第二铰链板210包括第二连接部211和与第二连接部211相连且朝向箱体1的前侧延伸的第二延伸部212。第二连接部211连接在箱体1的前侧壁上，且位于箱体1高度方向上的中部。第二连接部211具有多个通孔2111，箱体1具有多个螺纹孔，多个所述螺纹孔设置在箱体1的前侧壁中且与多个通孔2111对应，通过紧固件如螺钉可以将第二连接部211与箱体1固定连接。
第二铰链轴组220设置在第二延伸部212的上表面，且从第二延伸部212的上表面向上延伸。所述第二铰链槽组对应于第二铰链轴组220设置在第一门体201的下端。第二铰链轴组220插设在所述第二铰链槽组中，且与所述第二铰链槽组相配合。
这样，箱体1和第一门体201通过第二铰链组件200连接，第一门体201可通过第二铰链组件200相对于箱体1旋转。
在一些实施例中，第三铰链组件300包括第三铰链板、第三铰链轴组320和第三铰链槽组。
所述第三铰链板包括第三连接部和与所述第三连接部相连且朝向箱体1的前侧延伸的第三延伸部。所述第三连接部连接在箱体1的前侧壁上，且位于第二连接部211的下方。所述第三连接部通过紧固件如螺钉与箱体1固定连接。
第三铰链轴组320设置在所述第三延伸部的下表面，且从第三延伸部212的下表面向下延伸。所述第三铰链槽组对应于第三铰链轴组320设置在第二门体202的上端。第三铰链轴组320插设在所述第三铰链槽组中，且与所述第三铰链槽组相配合。
这样，箱体1和第二门体202通过第三铰链组件300连接，第二门体202可通过第三铰链组件300相对于箱体1旋转。
在一些实施例中，参见图4，第三铰链组件300与第二铰链组件200共享第二铰链板210，即，第三铰链轴组320设置在第二延伸部212的下表面，且从第二延伸部212的下表面向下延伸，以插设在所述第三铰链槽组中。
在一些实施例中，第四铰链组件400包括第四铰链板、第四铰链轴组和第四铰链槽组。
所述第四铰链板包括第四连接部和与所述第四连接部相连的第四延伸部。所述第四连接部连接在箱体1的下侧壁。所述第四连接部通过紧固件如螺钉与箱体1固定连接。
所述第四铰链轴组设置在所述第四延伸部上，且从所述第四延伸部的上表面向上延伸。所述第四铰链槽组对应于所述第四铰链轴组设置在第二门体202的下端。所述第四铰链轴组插设在所述第四铰链槽组中，且与所述第四铰链槽组相配合。
这样，箱体1和第二门体202通过第四铰链组件400连接，第二门体202可通过第四铰链组件400相对于箱体1旋转。
需要说明的是，铰链轴组(如第一铰链轴组120、第二铰链轴组220、第三铰链轴组320或所述第四铰链轴组)和铰链槽组(如第一铰链槽组130、所述第二铰链槽组、所述第三铰链槽组或所述第四铰链槽组)的位置并不局限于上述实施例中的设置。例如，所述铰链轴组和所述铰链槽组的位置可以互换，也就是说，所述铰链轴组可以设置在门体2(如第一门体201和第二门体202)上，且所述铰链槽组可以对应所述铰链轴组设置在铰链板(如第一铰链板110、第二铰链板210、所述第三铰链板或所述第四铰链板)中。
在一些实施例中，如图7和图8所示，冰箱1000还包括旋停机构7。旋停机构7设置在铰链组件3与门体2之间，且被配置为使门体2停止旋转，避免门体2在被用户打开后因重心偏移而自动关闭。
参照图7至图9，旋停机构7包括弹性柱塞71和限位凹部72。弹性柱塞71和限位凹部72中的一者相对于门体2固定，另一者相对于铰链组件3(或箱体1)固定，在门体2旋转的过程中，弹性柱塞71相对于限位凹部72运动，且当弹性柱塞71相对地运动至限位凹部72的位置处时，弹性柱塞71卡入限位凹部72，从而使得门体2相对箱体1停止旋转(即门体2旋停)。当门体2旋停时，用户只需要对门体2施加一定的作用力，即可使得弹性柱塞71与限位凹部72脱离配合，即使门体2旋转打开或关闭。
在一些实施例中，旋停机构7包括弹性柱塞71限位凹部72。
在一些实施例中，如图7和图8所示，弹性柱塞71为球头式柱塞。弹性柱塞71包括支撑件711、弹性件712、限位凸部713和容纳腔714。
支撑件711呈轴状。支撑件711的一侧表面凹进以形成容纳腔714，且容纳腔714具有开口7141，例如，支撑件711轴向的一端向靠近其轴向的另一端的方向凹进，以形成容纳腔714，且容纳腔714的开口7141朝向远离支撑件711的所述一端方向。
弹性件712设置在容纳腔714中。弹性件712的一端与容纳腔714的腔底抵接，且弹性件712的另一端与限位凸部713抵接，以使得限位凸部713在弹性件712的作用下相对于支撑件711可运动。限位凸部713的至少一部分设于容纳腔714中，且位于开口7141处。当限位凸部713从容纳腔714中伸出并卡入限位凹部72时，门体2旋停。
在一些实施例中，如图10所示，支撑件711的外表面构造为外螺纹，以便于将弹性柱塞71安装至所述铰链板或门体2上。弹性件712例如为弹簧。限位凸部713可构造为球状体，以减少限位凸部713与其他部件(如门体2或所述铰链板)的接触面积，从而可以降低限位凸部713与其他部件之间的摩擦力。
如图6所示，对应于限位凸部713，限位凹部72可构造为球状凹槽，从而使得限位凸部713可以顺畅地滑入限位凹部72，或从限位凹部72中滑出，有利于提高门体2旋停或恢复旋转时的顺畅性。
在一些实施例中，弹性柱塞71具有伸出状态和缩回状态。如图7所示，当限位凸部713与限位凹部72相错时，限位凸部713与门体2或铰链板抵接，使得限位凸部713压缩弹性件712并缩回至容纳腔714中，弹性柱塞71处于所述缩回状态。如图8所示，当限位凸部713从容纳腔714中伸出并卡入限位凹部72中时，弹性柱塞71处于所述伸出状态。
示例性地，参照图7和图8，弹性柱塞71相对所述铰链板(例如，包括图7和图8中 所示的第二铰链板210)固定，限位凹部72设置在门体2上。如图7所示，当弹性柱塞71与限位凹部72相错时，限位凸部713与门体2滑动接触，从而使得弹性柱塞71与门体2之间的摩擦力较小，可以有效避免影响门体2打开或关闭的流畅度。如图8所示，当弹性柱塞71随着门体2的旋转运动至与限位凹部72相对时，限位凸部713从容纳腔714中伸出并卡入限位凹部72，使得门体2旋停。
可以理解的是，当用户再次对门体2施加作用力时，由于杠杆作用和限位凸部713的球状结构，使得限位凸部713可以从限位凹部72脱出，并由所述伸出状态转变为所述缩回状态，从而使门体2可旋转。
需要说明的是，弹性柱塞71和限位凹部72的位置并不局限于上述实施例中的设置。例如，弹性柱塞71和限位凹部72的位置可以互换，也就是说，弹性柱塞71可以设置在门体2上，且限位凹部72可以对应弹性柱塞71设置在所述铰链板上。
在一些实施例中，如图11及图12所示，铰链组件3为单轴铰链，即，铰链组件3中的铰链轴组包括一个铰链轴，铰链槽组包括一个铰链槽。在所述单轴铰链的作用下，门体2相对箱体1仅进行旋转运动。在此情况下，弹性柱塞71设置在所述铰链板中，限位凹部72设置在门体2中。
以下，将以弹性柱塞71设置在第一铰链板110上，限位凹部72设置在第一门体201的上端部为例进行说明，可以理解的是，弹性柱塞71还可以设置在第二铰链板210、所述第三铰链板或所述第四铰链板中，且限位凹部72可以相对应地设于第一门体201或第二门体202中，本公开对此不再赘述。
在一些实施例中，如图12所示，第一门体201包括旋停槽20。第一门体201的上表面向下凹进以形成旋停槽20。例如，旋停槽20呈圆弧状，且围绕第一铰链槽组130中的所述铰链槽设置。第一铰链槽组130中的所述铰链槽位于旋停槽20的圆心位置处。
如图11所示，弹性柱塞71与第一铰链板110固定连接。例如，弹性柱塞71设置在第一延伸部112上，并从第一延伸部112的下表面向下延伸，以插设在旋停槽20中。例如，弹性柱塞71平行于第一铰链轴组120中的所述铰链轴。
限位凹部72设置在旋停槽20的槽底。在第一门体201打开或关闭的过程中，弹性柱塞71在旋停槽20中运动。这样，在第一门体201打开或关闭的过程中，当弹性柱塞71与旋停槽20内的限位凹部72相错时，弹性柱塞71处于所述缩回状态，第一铰链轴组120可以在第一铰链槽组130中做旋转运动，第一门体201可以以第一铰链轴组120为旋转轴，旋转打开或关闭。当第一门体201旋转至弹性柱塞71与旋停槽20内的限位凹部72相对时，弹性柱塞71处于所述伸出状态，限位凸部713卡入限位凹部72内以限位第一门体201，使第一门体201旋停。
在一些实施例中，如图12所示，旋停机构7包括多个限位凹部72，多个限位凹部72设置在旋停槽20中的不同位置处，以使门体2可以在打开至多个角度时旋停。
例如，旋停机构7包括两个限位凹部72，一个限位凹部72位于旋停槽20的端部，以使门体2在打开至最大角度时旋停；另一个限位凹部72位于旋停槽20的中部，这样，门体2可以在打开至例如40°至50°之间的任一角度时旋停。
需要说明的是，限位凹部72还可以设置在旋停槽20中的其他位置处，本公开对此不做限定。
通常情况下，铰链组件3位于门体2的左侧或右侧，如图1、图2和图13所示，门体2包括左侧壁、右侧壁、上侧壁、下侧壁和前侧壁。为描述方便，将门体2的左侧壁和右侧壁中更靠近铰链组件3的一侧壁称为门侧壁21。例如，在图1和图2中，铰链组件3设置在门体2的左端(即，用户的右端)，则门体2的左侧壁被称为门侧壁21，门体2的右端以其左端为旋转中心进行旋转运动。门体2的前侧壁被称为门前壁22，门体2的门前壁22和门侧壁21交汇形成角棱23。
类似地，当铰链组件3设置在门体2的右端时，门体2的右侧壁被称为门侧壁21，门 体2的左端以其右端为旋转中心进行旋转运动。
箱体1包括左侧壁、右侧壁、上侧壁、下侧壁和后侧壁。在一些实施例中，将箱体1的左右两侧壁中靠近铰链组件3的一侧壁所在的平面定义为参考平面M。以参考平面M为分界面，箱体1所在的一侧被定义为内侧，与之相对的另一侧被定义为外侧。如图1、图13和图14所示，铰链组件3设置在箱体1的左端，则箱体1的左侧壁被定义为参考平面M，所述内侧为参考平面M的右侧。
可以理解的是，当铰链组件3设置在箱体1的右端时，箱体1的右侧壁被定义为参考平面M，所述内侧为参考平面M的左侧。
如图7所示，将冰箱1000嵌入橱柜4中时，考虑到地面不平或橱柜4变型等因素，需要在冰箱1000的外侧壁(对应参考平面M所在位置)与橱柜4的内侧壁之间预留间隙α，间隙α的宽度小于或等于5mm，例如，间隙α的宽度可以为4mm、4.5mm或5mm。
可以理解的是，为了保证门体2正常打开，门体2在旋转的过程中，其角棱23超出参考平面M的距离(即，随着门体2的旋转，当角棱23从参考平面M运动到所述外侧时，角棱23与参考平面M之间的距离)不宜太大，例如，该距离不大于5mm，以避免角棱23与橱柜4碰撞，导致门体2无法完全打开，进而导致门体2或橱柜4损坏。
在一些实施例中，如图15和图16所示，铰链组件3为双轴铰链，即，铰链组件3中的铰链轴组包括两个铰链轴，且铰链槽组包括两个铰链槽。两个所述铰链轴分别与两个所述铰链槽相配合，以使门体2在打开的同时向所述内侧移动一定距离，也就是说，门体2在旋转打开的同时，带动角棱23向所述内侧移动，从而避免角棱23与橱柜4发生碰撞。在此情况下，旋停机构7设置在铰链组件3中。
以下，将以旋停机构7设置在第一铰链组件100中为例进行说明，可以理解的是，在一些实施例中，旋停机构7也可以设置在第二铰链组件200、第三铰链组件300或第四铰链组件400中，其具有相同的效果，本公开对此不做赘述。
在一些实施例中，如图15和图16所示，第一铰链轴组120包括定位轴121和导向轴122。第一铰链槽组130包括定位槽131和导向槽132。定位轴121与定位槽131相配合，且导向轴122与导向槽132相配合。定位槽131位于导向槽132的一端与门侧壁21之间。
在第一门体201打开的过程中，定位轴121相对地在定位槽131中运动(该运动过程将在下文中进行详细介绍)，导向轴122相对地在导向槽132中运动(该运动过程将在下文中进行详细介绍)，以使第一门体201在旋转的同时沿冰箱1000的宽度方向(即如图1中所示的左右方向)运动，避免与橱柜4发生碰撞。
在一些实施例中，如图15和图16所示，弹性柱塞71设置在定位轴121中，例如，弹性柱塞71的支撑件711与定位轴121为一体件。定位轴121的下端面向上凹进，以形成容纳腔714。在此情况下，限位凹部72设置在定位槽131的槽底。可以理解的是，定位轴121和定位槽131的配合主要起定位作用，而导向轴122和导向槽132的配合主要起导向作用。因此，定位轴121的长度大于导向轴122的长度，使得定位轴121插入定位槽131的部分的长度，大于导向轴122插入导向槽132的部分的长度。定位轴121的直径大于导向轴122的直径。
由于定位轴121的长度大，弹性柱塞71中的容纳腔714在定位轴121的轴向上的深度可以设置的较大，这样，限位凸部713相对于容纳腔714在定位轴121的轴向上进行的伸缩移动的位移可以更大，有利于提高门体2旋停的稳定性。另外，由于弹性柱塞71的直径大，弹性柱塞71中的容纳腔714在定位轴121的径向上的尺寸可以设置的较大，这样，限位凸部713的直径可以设置的较大，从而可以扩大限位凸部713与限位凹部72的配合面积，提高门体2旋停的稳定性。
在一些实施例中，参照图17和图18，弹性柱塞71设置在导向轴122中，例如，弹性柱塞71的支撑件711与导向轴122为一体件。导向轴122的下端面向上凹进，以形成容纳腔714。在此情况下，限位凹部72设置在导向槽132的槽底。
可以理解的是，定位轴121和定位槽131配合主要起定位作用，导向轴122和导向槽132配合主要起导向作用，因此，导向槽132的长度设置为大于定位槽131的长度。这样，可以在导向槽132的槽底上设置多个限位凹部72。多个限位凹部72沿导向槽132的延伸方向排列，以使门体2可以在打开至多个角度时旋停。例如，多个限位凹部72分别设置在导向槽132的端部和中部，以使门体2可以在打开至0°、45°、90°和最大角度等位置处时旋停。
为便于描述，将门体2处于关闭状态时第一铰链轴组120在第一铰链槽组130中的位置定义为第一旋停位置(即0°位置，如图19中所示的70A处)，例如，当门体2处于所述关闭状态时，导向轴122在导向槽132中的位置为导向槽132的第一旋停位置，定位轴121在定位槽131中的位置为定位槽131的第一旋停位置。
类似的，当门体2打开至45°(即，第一预设角度)时，第一铰链轴组120在第一铰链槽组130中的位置定义为第二旋停位置(即45°位置，如图20中所示的70B处)。当门体2打开至90°(即，第二预设角度)时，第一铰链轴组120在第一铰链槽组130中的位置定义为第三旋停位置(即90°位置，如图21中所示的70C处)。
当冰箱1000嵌入橱柜4中时，门体2可以打开至第四角度，所述第四角度约为100°至105°之间的任一值。当门体2打开至所述第四角度时，第一铰链轴组120在第一铰链槽组130中的位置定义为第四旋停位置(即最大嵌入打开位置)。
当冰箱1000未嵌入橱柜4中时，门体2可以打开至第五角度，所述第五角度约为100°至105°之间的任一值。当门体2打开至所述第五角度时，第一铰链轴组120在第一铰链槽组130中的位置定义为第五旋停位置(即最大正常打开位置)。可以理解的是，由于导向槽132较长，导向槽132的所述第一旋停位置、所述第二旋停位置、所述第三旋停位置以及所述第四旋停位置等，间隔开排列且间隔的距离较大，因此，可以在导向槽132内的多个位置(如0°位置、45°位置等)处设置限位凹部72，以使门体2在打开至多个预设的角度时旋停。
另外，当用户拉动门体2时，会对门体2施加作用力，该作用力会首先传递至导向轴122和导向槽132，由导向轴122与导向槽132相配合，带动门体2在旋转的同时向所述内侧移动。因此，通过将弹性柱塞71设置在导向轴122中，将限位凹部72设置在导向槽132中，可以优化门体2的受力效果，使门体2可以及时旋停或重新旋转。
在一些实施例中，如图22和图23所示，旋停机构7包括两个弹性柱塞71和多个限位凹部72。两个弹性柱塞71分别设置在定位轴121和导向轴122中，且多个限位凹部72分别设置在定位槽131的槽底和导向槽132的槽底。
如此一来，既可在导向槽132中设置多个限位凹部72，以实现门体2在多个角度的旋停，又可在定位轴121中设置较粗且较长的弹性柱塞71以提高门体2在旋停时的稳定性。可以理解的是，在以上的实施例中，弹性柱塞71设置在第一铰链轴组120中，限位凹部72设置在第一铰链槽组130中。在门体2打开或关闭的过程中，当铰链轴(包括定位轴121和导向轴122)在其对应的铰链槽(包括定位槽131和导向槽132)中运动，弹性柱塞71也跟随所述铰链轴相对所述铰链槽运动。
在此过程中，当弹性柱塞71与限位凹部72相错时，限位凸部713与所述铰链槽的槽底相接触，并在所述铰链槽的槽底上滑动。由于限位凸部713与所述铰链槽的槽底之间的摩擦力较小，因此，旋停机构7不会影响门体2的旋转。当门体2运动至弹性柱塞71与限位凹部72相对时，限位凸部713卡入限位凹部72中，使得门体2在弹性柱塞71与限位凹部72的限位作用下旋停。在此情况下，若有外力(如用户对门体2施加的作用力)作用于门体2，则门体2将克服弹性柱塞71的阻力，使限位凸部713压缩弹性件712并缩回至容纳腔714中，使得门体2继续旋转。
在一些实施例中，如图24所示，铰链组件3中的铰链轴的远离铰链板的一端敞开以形成安装孔301，弹性柱塞71安装在安装孔301中。
例如，安装孔301朝向铰链槽的槽底的一端敞开，且所述铰链槽中设有限位凹部72。
需要说明的是，基于上述特征的旋停机构7可设置在第一铰链组件100、第二铰链组件200、第三铰链组件300和第四铰链组件400中的一个铰链组件或多个铰链组件中。
以下，将以旋停机构7设置在第一铰链组件100中为例进行说明。
在一些实施例中，旋停机构7设置在第一铰链组件100中，第一铰链组件100中的铰链轴(包括定位轴121和导向轴122)的远离第一铰链板110的一端敞开以形成安装孔301。铰链槽32的槽底即为铰链槽32的底面。弹性柱塞71通过螺纹连接的形式安装在安装孔301内(如图10所示)，这样，弹性柱塞71的限位凸部713位于容纳腔714的端部，即，位于安装孔301处。
在所述铰链轴相对所述铰链槽运动的过程中，限位凸部713受到所述铰链槽的所述槽底的止挡而向上压缩弹性件712，弹性柱塞71处于所述缩回状态；当所述铰链轴运动到限位凹部72的位置处时，限位凸部713在弹性件712弹力的作用下弹出，并卡入限位凹部72内，此时，弹性柱塞71处于所述伸出状态。
可以理解的是，当旋停机构7设置在位于门体2上端的铰链组件3(如第一铰链组件100和/或第三铰链组件300)中时，在弹性柱塞71处于所述伸出状态且弹性件712处于自然状态(即，弹性件712不对限位凸部713施加弹力)的情况下，弹性柱塞71可能会由于装配误差等原因而没有完全卡入限位凹部72，导致弹性柱塞71易脱离限位凹部72而使得门体2旋停不稳定。因此，在一些实施例中，当弹性柱塞71处于伸出状态时，弹性件712依然处于压缩状态(即，弹性件712对限位凸部713施加弹力)。这样，弹性件712可推动限位凸部713卡入限位凹部72内，有利于提高门体2旋停的稳定性。
当旋停机构7设置在门体2下端的铰链组件3(即，第二铰链组件200和/或第四铰链组件400)中时，铰链轴从铰链板的上表面向上延伸，所述铰链轴的上表面向下凹进以形成安装孔301，铰链槽的槽底即为铰链槽的顶面。弹性柱塞71的限位凸部713位于所述铰链轴的端部，即，位于安装孔301处。
在所述铰链轴相对所述铰链槽运动的过程中，限位凸部713在门体2的作用下，向下压缩弹性件712。可以理解的是，由于弹性柱塞71受到门体2的作用，使得弹性柱塞71在运动过程中的受力稳定，从而可以保证限位凸部713卡入限位凹部72的稳定性，有利于提高门体2旋停时的稳定性。
在一些实施例中，弹性柱塞71可安装在所述铰链轴中，且弹性柱塞71的延伸方向(即，弹性件712至限位凸部713的排布方向)垂直所述铰链轴的轴线，也就是说，限位凸部713位于所述铰链轴的侧壁处，且限位凸部713相对于支撑件711的伸缩方向与所述铰链轴的轴线垂直。相应地，限位凹部72设置在所述铰链槽的槽壁上，这样，当限位凹部72回缩至支撑件711中时，门体2可旋转，当限位凹部72卡入位于所述铰链槽的槽壁上的限位凹部72时，门体2可旋停。
在一些实施例中，如图24和图25所示，所述铰链轴与弹性柱塞71的支撑件711为一体件，即，所述铰链轴的远离所述铰链板的一端向靠近所述铰链板的方向凹进以形成容纳腔714。弹性件712和限位凸部713安装在容纳腔714中。这样，可以简化旋停机构7与所述铰链轴的安装结构，有利于降低产品成本。
在一些实施例中，如图26所示，沿冰箱1000的高度方向，门体2与所述铰链板之间预留有间隙，以便于将门体2安装至箱体1的前端。
例如，第一门体201与第一铰链板110之间具有间隙，且第一门体201与第二铰链板210之间也具有间隙。当第一门体201安装在箱体1的前端时，在重力作用下，第一门体201与第二铰链板210接触，而第一门体201与第一铰链板110之间的间隙的宽度增大，第一门体201与第一铰链板110之间间隔开第一距离H1，也就是说，第一铰链槽组130的槽顶与第一铰链板110之间间隔开第一距离H1。
在一些实施例中，限位凹部72设置在所述铰链槽组中的0°位置，以使门体2在处于 所述关闭状态时旋停，从而可以避免门体2在运输过程中因晃动而打开。
在弹性柱塞71从所述伸出状态回缩至所述回缩状态的过程中，限位凸部713的运动距离为第二距离H2。可以理解的是，在弹性柱塞71从所述回缩状态伸出至所述伸出状态的过程中，限位凸部713的运动距离也为第二距离H2，且第二距离H2小于第一距离H1。这样，当冰箱1000在运输过程中发生运输跌落时，可以避免门体2因上窜碰撞所述铰链板，例如，可以避免第一门体201因上窜碰撞第一铰链板110。
在一些实施例中，当限位凸部713处于所述缩回状态时，弹性件712处于极限压缩状态，且限位凸部713的一部分从开口7141露出(如图7所示)。这样设置，一方面，当门体2因上窜而向上挤压限位凸部713时，限位凸部713不会完全缩回至容纳腔714中，使门体2对所述铰链轴组造成冲击。另一方面，限位凸部713的一部分从开口7141露出，使限位凸部713始终与所述铰链槽组滚动接触，从而可以降低所述铰链轴组与所述铰链槽组之间的移动摩擦力，有利于提高门体2打开或关闭时的流畅度。
在一些实施例中，当冰箱1000嵌入橱柜4使用时，可以打开至第四角度，且所述第四角度大于90°。参见图27，当冰箱1000打开至所述第四角度时，将所述铰链轴组(如第一铰链轴组120)在所述铰链槽组(如第一铰链槽组130)中的位置定义为第四旋停位置(如图27中70D处)。
在一些实施例中，弹性柱塞71设置在导向轴122中，且限位凹部72设置在导向槽132中的第四旋停位置处，以使门体2在打开至所述第四角度时旋停，从而可以避免门体2碰撞橱柜4。
在一些实施例中，旋停机构7包括两个弹性柱塞71，且两个弹性柱塞71分别设置在定位轴121和导向轴122中，限位凹部72分别设置在定位槽131和导向槽132中的所述第四旋停位置处，以提高门体2在打开至所述第四角度时，旋停的稳定性。
需说明的是，旋停机构7可以包括一个弹性柱塞71或两个弹性柱塞71，当旋停机构7包括一个弹性柱塞71时，弹性柱塞71可以设置在定位轴121或导向轴122中的一者中，限位凹部72可以是设置在定位槽131和导向槽132中，也可以是对应于弹性柱塞71，仅设置在定位槽131或导向槽132中，本公开对此不做限定。
以下，将以设置在箱体1上部的第一铰链组件100为例，结合第一铰链轴组120相对与第一铰链槽组130的运动轨迹，对第一门体201相对于箱体1打开的过程进行介绍。可以理解的是，第二铰链组件200、第三铰链组件300、第四铰链组件400与第一铰链组件100的工作原理相同，本公开对此不再赘述。
【第一运动轨迹】
参照图13和图14，当第一门体201处于关闭状态时，定位槽131为直线槽，且平行于门前壁22。
在第一运动轨迹中，第一门体201从关闭状态打开至最大角度的过程包括第一阶段至第五阶段，且，第一门体201、定位轴121和导向轴122的运动趋势如表1所示。
表1 第一运动轨迹中的门体、定位轴和导向轴的运动趋势
Figure PCTCN2022132691-appb-000001
<第一阶段>
参照图28，定位槽131包括第一定位位置51和第二定位位置52，且第二定位位置52较第一定位位置51远离门侧壁21。导向槽132包括第一导向位置61和第二导向位置62，且第二导向位置62较第一导向位置61远离门前壁22且远离门侧壁21。
在第一门体201由所述关闭状态打开至第一角度的过程中，定位轴121相对定位槽131从第一定位位置51移动到第二定位位置52的同时，导向轴122相对导向槽132从第一导向位置61移动到第二导向位置62。
可以理解的是，如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201在旋转的同时向所述外侧移动了一定距离。
如图28所示，第一定位位置51与第二定位位置52之间的距离比较小，也就是说，在第一阶段中，第一门体201在旋转的同时稍向所述外侧移动。
可以理解的是，在第一阶段中，第一门体201打开的角度较小，因此，角棱23因第一门体201的旋转而超出参考平面M的距离较小，且不会与橱柜4发生碰撞。
在第一阶段中，导向轴122相对导向槽132的运动轨迹为第一导向轨迹线612；在第二阶段中，导向轴122相对导向槽132的运动轨迹为第二导向轨迹线623。
在第一阶段中，第一导向轨迹线612向远离门前壁22且远离门侧壁21的方向延伸，以使得第一导向轨迹线612与第二导向轨迹线623的过渡点光滑，有利于提高第一门体201运动的流畅性。
另外，第一导向轨迹线612向远离门前壁22和远离门侧壁21的方向延伸，可以增大第一导向轨迹线612与定位轴121在第一阶段中的运动轨迹线(即，定位轴121从第一定位位置51移动到第二定位位置52的轨迹线)之间的夹角，从而有利于提高门体2在运动的过程中的稳定性。在一些实施例中，第二定位位置52较第一定位位置51靠近门侧壁21，第二导向位置62较第一导向位置61远离门前壁22且靠近门侧壁21。这样，在第一阶段中，第一门体201在旋转的同时向所述内侧移动。
在一些实施例中，第一角度为15°至25°之间的任一值。例如，第一角度为15°、18°、21°或25°。
<第二阶段>
参照图29，定位槽131还包括第三定位位置53，第三定位位置53较第二定位位置52(以及第一定位位置51)靠近门侧壁21。导向槽132还包括第三导向位置63，第三导向位置63较第二导向位置62远离门前壁22且靠近门侧壁21。
在第一门体201由所述第一角度打开至第二角度的过程中，定位轴121相对定位槽131从第二定位位置52移动到第三定位位置53的同时，导向轴122相对导向槽132从第二导向位置62运动到第三导向位置63。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201在旋转的同时向所述外侧移动了一定距离。
因此，当定位轴121从第二定位位置52移动到第三定位位置53，即定位轴121沿定位槽131向靠近门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向所述内侧移动。因此，在第二阶段中，第一门体201在旋转的同时会向所述内侧移动一段距离，从而使角棱23相对参考平面M向所述内侧移动，以避免角棱23与橱柜4的碰撞。在一些实施例中，在第一阶段中，第一门体201每旋转单位角度向所述外侧移动的距离为μ1，在第二阶段中，第一门体201每旋转单位角度向所述内侧移动的距离为μ2，且μ1小于μ2。
这样，可以避免第一门体201在第一阶段中因向所述外侧移动距离过大而与箱体1的前端面(即箱体1的靠近第一门体201的端面)发生横向摩擦，且有利于提高用户开启第 一门体201时的手感和流畅度。
例如，第一导向轨迹线612的斜率大于第二导向轨迹线623的斜率(本公开所描述的斜率均为绝对值)。可以理解的是，轨迹线的斜率越大，第一门体201在旋转单位角度时，向所述外侧或所述内侧移动的距离越小。
需要说明的是，如果在第一阶段和第二阶段中，第一门体201在旋转的同时都向所述内侧移动，那么，为了使第一门体201在第一阶段中向所述内侧移动的幅度较小，需要在第一导向轨迹线612和第二导向轨迹线623的连接处设置曲率变化点，该曲率变化点为导向轨迹线(包括第一导向轨迹线612和第二导向轨迹线623)的尖点，这样，会降低用户打开第一门体201的手感。
因此，通过设置第一门体201在第一阶段中向所述外侧发生横向移动，可以使第一导向轨迹线612和第二导向轨迹的连接处平滑，有利于提高第一门体201运动的流畅性。
在一些实施例中，第二导向轨迹线623与定位轴121的运动轨迹线之间的夹角大于45°，以避免定位轴121与导向轴122的运动趋势接近平行时，第一门体201发生晃动，有利于提高第一门体201打开时的稳定性。
在一些实施例中，第二角度为46°至75°之间的任一值。例如，第二角度为46°、55°、65°、或75°。
<第三阶段>
参照图30，定位槽131还包括第四定位位置54，第四定位位置54较第三定位位置53远离门侧壁21。导向槽132还包括第四导向位置64，第四导向位置64较第三导向位置63远离门前壁22且靠近门侧壁21。
在第一门体201由所述第二角度打开至第三角度的过程中，定位轴121相对定位槽131从第三定位位置53移动到第四定位位置54的同时，导向轴122相对导向槽132从第三导向位置63运动到第四导向位置64。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201在旋转的同时向所述外侧移动了一定距离。
因此，当定位轴121从第三定位位置53移动到第四定位位置54，即定位轴沿定位槽131是向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向所述外侧移动。因此，在第三阶段中，第一门体201在旋转的同时向所述外侧移动。
可以理解的是，第一门体201在第二阶段中已度过了可能与橱柜4发生碰撞的危险点(即，第一门体201打开至45°至48°时)，因此，在第三阶段中，第一门体201即使在旋转的同时向所述外侧移动，也不会与橱柜4发生碰撞。并且，第一门体201向所述外侧移动时还可以减少对所述储藏间室的遮挡，以避免因第一门体201的阻挡而导致所述储藏间室内的抽屉无法抽出。
在一些实施例中，第三角度为90°。
在一些实施例中，当第一门体201打开至第三角度时，门前壁22与参考平面M平齐，从而可以进一步减小第一门体201占据所述储藏间室的前方的空间，避免第一门体201对所述储藏间室内抽屉抽出的影响。
在一些实施例中，当第一门体201打开至第三角度时，第一门体201位于参考平面M的内侧，即第一门体201的门前壁22与参考平面M间隔开，以使得第一门体201可以由第三角度(即，90°)继续打开至更大的角度。
<第四阶段>
参照图31，定位槽131还包括第五定位位置55，第五定位位置55较第四定位位置54远离门侧壁21。导向槽132还包括第五导向位置65，第五导向位置65较第四导向位置64远离门前壁22且靠近门侧壁21。
在第一门体201由所述第三角度打开至第四角度的过程中，定位轴121相对定位槽131从第四定位位置54移动到第五定位位置55的同时，导向轴122相对导向槽132从第四导向位置64运动到第五导向位置65。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201向所述内侧且靠近箱体1的方向移动。
在一些实施例中，当冰箱1000嵌入橱柜4时，第四角度为第一门体201所能打开的最大嵌入打开角度。
在一些实施例中，第四角度为100°至105°之间的任一值。例如，第四角度为100°、102°或105°。
<第五阶段>
参照图32，定位槽131还包括第六定位位置56，第六定位位置56较第五定位位置55远离门侧壁21。导向槽132还包括第六导向位置66，第六导向位置66较第五导向位置65靠近门前壁22且靠近门侧壁21。
当冰箱1000未嵌入橱柜4时，第一门体201可以打开至第五角度，且第五角度大于第四角度。在第一门体201由所述第四角度打开启至最大角度(即，第五角度)的过程中，定位轴121相对定位槽131从第五定位位置55移动到第六定位位置56，导向轴122相对导向槽132从第五导向位置65移动到第六导向位置66。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201向所述内侧且靠近箱体1的方向移动。
在一些实施例中，第五角为130°至135°之间的任一值。例如，第五角度为130°、132°或135°。
在第一阶段至第五阶段中，即，在第一门体201由所示关闭状态打开至所示第五角度的过程中，定位轴121在定位槽131中来回移动，导向轴122从导向槽132的一端运动到导向槽132的另一端。
【第二运动轨迹】
参照图33，与第一运动轨迹不同的是，在第二运动轨迹中，定位槽131包括延伸方向不同的第一槽段501A和第二槽段502A。第一槽段501A的一端较其另一端更远离门侧壁21，第二槽段502A的一端与第一槽段501A的所述另一端相连，且第二槽段502A的另一端向靠近门前壁22且靠近门侧壁21的方向延伸。第二槽段502A为曲线槽。导向槽132大体上为向远离门前壁22且靠近门侧壁21的方向延伸的曲线槽。
在一些实施例中，定位槽131的第二槽段502A为直线槽，导向槽132为直线槽，或者，导向槽132的一部分为直线槽。
在第二运动轨迹中，第一门体201从关闭状态打开至最大角度的过程包括第一阶段至第五阶段，且，第一门体201、定位轴121和导向轴122的运动趋势如表2所示。

<第一阶段>
参照图34，定位槽131包括第一定位位置51A和第二定位位置52A，且第二定位位置52A较第一定位位置51A靠近门侧壁21。导向槽132包括第一导向位置61A和第二导向位置62A，且第二导向位置62A较第一导向位置61A远离门前壁22且靠近门侧壁21。
在第一门体201由所述关闭状态打开至所述第一角度的过程中，导向轴122相对导向槽132从第一导向位置61A运动到第二导向位置62A的同时，定位轴121相对定位槽131从第一定位位置51A移动到第二定位位置52A。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201在旋转的同时向所述内侧移动了一定距离。
<第二阶段>
参照图35，定位槽131包括第二定位位置52A和第三定位位置53A，且第三定位位置53A较第二定位位置52A靠近门侧壁21。导向槽132包括第二导向位置62A和第三导向位置63A，且第三导向位置63A较第二导向位置62A远离门前壁22且靠近门侧壁21。
在第一门体201由所述第一角度打开至所述第二角度的过程中，定位轴121相对定位槽131从第二定位位置52A移动到第三定位位置53A的同时，导向轴122相对导向槽132从第二导向位置62A运动到第三导向位置63A。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201在旋转的同时向所述内侧移动一定距离，从而使角棱23相对参考平面M向所述内侧移动，以避免角棱23与橱柜4的碰撞。
在第一阶段中，导向轴122相对导向槽132的运动轨迹为第一导向轨迹线612A；在第二阶段中，导向轴122相对导向槽132的运动轨迹为第二导向轨迹线623A。
第一导向轨迹线612A和第二导向轨迹线623A的连接处具有趋势变化点，使得第一门体201在打开单位角度时，向所述内侧移动的距离在第一阶段和第二阶段不相同，且第一阶段的单位角度的所述内侧移动的距离小于第二阶段的单位角度的所述内侧移动的距离。
例如，在第一阶段中，第一门体201每旋转单位角度向所述内侧移动的距离为μ3，在第二阶段中，第一门体201每旋转单位角度向所述内侧移动的距离为μ4，且μ3小于μ4。
这样，可以避免第一门体201在第一阶段中因向所述内侧移动距离过大而与箱体1的所述前端面发生横向摩擦。
<第三阶段>
参照图36，定位槽131还包括第四定位位置54A，第四定位位置54A较第三定位位置53A靠近门侧壁21和门前壁22。导向槽132还包括第四导向位置64A，第四导向位置64A较第三导向位置63A靠近门侧壁21且远离门前壁22。
在第一门体201由所述第二角度打开至所述第三角度的过程中，定位轴121相对定位槽131从第三定位位置53A移动到第四定位位置54A的同时，导向轴122相对导向槽132从第三导向位置63A移动到第四导向位置64A。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201在旋转的同时向所述内侧移动了一定距离。
在第一门体201由所述关闭状态到打开至第三角度的过程中，第一门体201始终向所述内侧移动，这样可以使得打开至所述第三角度时第一门体201位于参考平面M的内侧。因此，第一门体201打开至大于所述第三角度时才可能碰到橱柜4，使冰箱1000放置于橱柜4使用时的第一门体201的打开角度增大，更加便于用户取放食物。
<第四阶段>
参照图37，定位槽131还包括第五定位位置55A，第五定位位置55A较第四定位位置54A靠近门侧壁21和门前壁22。导向槽132还包括第五导向位置65A，第五导向位置65A较第四导向位置64A靠近门侧壁21且远离门前壁22。
在第一门体201由所述第三角度打开至所述第四角度的过程中，定位轴121相对定位槽131从第四定位位置54A移动到第五定位位置55A的同时，导向轴122相对导向槽132从第四导向位置64A移动到第五导向位置65A。
在第四阶段中，所述第四角度约为100°至105°之间的任一值。例如，为100°、102°或105°。第一门体201打开至所述第四角度而不会碰到橱柜4。
<第五阶段>
参照图38，定位槽131还包括第六定位位置56A，第六定位位置56A位于第五定位位置55A与第三定位位置53A之间。导向槽132还包括第六导向位置66A，第六导向位置66A较第五导向位置65A远离门前壁22且靠近门侧壁21。
当冰箱1000未嵌入橱柜4时，第一门体201可以打开至所述第五角度，且所述第五角度大于所述第四角度。在第一门体201由所述第四角度打开至所述第五角度的过程中，导向轴122相对导向槽132从第五导向位置65A移动到第六导向位置66A，定位轴121相对定位槽131从第五定位位置55A回撤移动到第六定位位置56A。
当第一门体201打开至第五角度时，角棱23位于参考平面M的内侧，定位轴121沿定位槽131向远离门前壁22和门侧壁21的方向移动，定位槽131相对于定位轴121向靠近参考平面M的方向移动，即角棱23向所述外侧移动，以避免第一门体201继续向所述内侧移动而占据所述储藏间室前方空间进而导致所述储藏间室内的抽屉等被第一门体201阻挡、无法抽出的问题。
【第三运动轨迹】
参照图39，与第二运动轨迹不同的是，在第三运动轨迹中，导向槽132先向远离门前壁22且靠近门侧壁21的方向延伸，再向靠近门侧壁21且靠近门前壁22的方向延伸。
定位槽131包括第一定位位置、第二定位位置，第三定位位置，第四定位位置、第五定位位置55B以及第六定位位置56B。导向槽132包括第一导向位置、第二导向位置、第三导向位置、第四导向位置、第五导向位置65B以及第六导向位置66B。第六导向位置66B相对第五导向位置65B靠近门前壁22，使定位轴121相对定位槽131移动时不会回撤。
在第三运动轨迹中，第一门体201从关闭状态打开至最大角度的过程包括第一阶段至第五阶段，且，第一门体201、定位轴121和导向轴122的运动趋势如表3所示。
表3 第三运动轨迹中的门体、定位轴和导向轴的运动趋势
Figure PCTCN2022132691-appb-000004
第三运动轨迹的第一阶段至第四阶段与第二运动轨迹的第一阶段至第四阶段的运动 趋势大体相同，此处不再赘述。
<第五阶段>
参照图40，第六定位位置56B较第五定位位置55B靠近门侧壁21且靠近门前壁22。第六导向位置66B较第五导向位置65B远离门前壁22且靠近门侧壁21。
在第一门体201由所述第三角度打开至所述第五角度的过程中，定位轴121相对定位槽131从第五定位位置55B移动到第六定位位置56B，导向轴122相对导向槽132从第五导向位置65B移动到第六导向位置66B。
【第四运动轨迹】
在第四运动轨迹中，定位槽131包括第一定位位置51C、第二定位位置52C，第三定位位置53C，第四定位位置、第五定位位置以及第六定位位置。导向槽132包括第一导向位置61C、第二导向位置62C、第三导向位置63C、第四导向位置、第五导向位置以及第六导向位置。
参照图41，与第二运动轨迹、第三运动轨迹不同的是，定位槽131还包括延伸方向不同的第一槽段501C、第二槽段502C和第三槽段503C。
第三槽段503C的一端较第三槽段503C的另一端更远离门侧壁21且靠近门前壁22。第一槽段501C的一端连接第三槽段503C的上述另一端，且第一槽段501C的另一端连接第二槽段502C的一端。第二槽段502C的另一端向靠近门侧壁21且靠近门前壁22的方向延伸。第一槽段501C平行于门前壁22。
在第四运动轨迹中，第一门体201从关闭状态打开至最大角度的过程包括第一阶段至第五阶段，且，第一门体201、定位轴121和导向轴122的运动趋势如表4所示。
表4 第四运动轨迹中的第一门体201、定位轴121和导向轴122的运动趋势
Figure PCTCN2022132691-appb-000005
对应定位槽131的形状的变化，第四运动轨迹的第一阶段和第二阶段与第二运动轨迹、第三运动轨迹不同，第三阶段至第五阶段与第二运动轨迹、第三运动轨迹相同，与第二运动轨迹、第三运动轨迹相同的部分不再赘述。
<第一阶段>
参照图42，第二定位位置52C较第一定位位置51C靠近门侧壁21且远离门前壁22，第二导向位置62C较第一导向位置61C靠近门侧壁21且远离门前壁22。
在第一门体201由所述关闭状态打开至所述第一角度的过程中，定位轴121相对定位槽131从第一定位位置51C运动到第二定位位置52C，导向轴122相对导向槽132从第一导向位置61C运动到第二导向位置62C。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201在旋转的同时向所述外侧移动了一定距离。
因此，当定位轴121从第一定位位置51C移动到第二定位位置52C，即定位轴121沿定位槽131向靠近门侧壁21且远离门前壁22的方向移动时，其实是定位槽131相对于定 位轴121向所述内侧且向远离箱体1的方向(如前侧)移动，使得第一门体201在旋转的同时向所述内侧以及向所述前侧移动一定距离。
可以理解的是，当第一门体201向所述内侧移动时，会带动角棱23向所述内侧移动，从而可以避免角棱23与橱柜4碰撞。第一门体201向所述前侧移动，可避免第一门体201向所述内侧移动时与箱体1的所述前端面发生摩擦。
<第二阶段>
参照图43，第三定位位置53C较第二定位位置52C靠近门侧壁21，第三导向位置63C较第二导向位置62C靠近门侧壁21且远离门前壁22。
在第一门体201由所述第一角度打开至所述第二角度的过程中，定位轴121相对定位槽131从第二定位位置52C移动到第三定位位置53C的同时，导向轴122相对导向槽132从第二导向位置62C移动到第三导向位置63C。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，以使得第一门体201在旋转的同时向所述内侧移动一定距离，从而使角棱23相对参考平面M向所述内侧移动，以避免角棱23与橱柜4的碰撞。
【第五运动轨迹】
参照图44，定位槽131和导向槽132均为曲线槽。
在第五运动轨迹中，第一门体201从关闭状态打开至最大角度的过程包括第一阶段至第四阶段，且，第一门体201、定位轴121和导向轴122的运动趋势如表5所示。
表5 第五运动轨迹中的第一门体201、定位轴121和导向轴122的运动趋势
Figure PCTCN2022132691-appb-000006
<第一阶段>
参照图45，定位槽131包括第一定位位置51D和第二定位位置52D，且第二定位位置52D较第一定位位置51D远离门前壁22且靠近门侧壁21。导向槽132包括第一导向位置61D和第二导向位置62D，且第二导向位置62D较第一导向位置61D远离门前壁22且靠近门侧壁21。
在第一门体201由所述关闭状态打开至所述第一角度的过程中，定位轴121相对定位槽131从第一定位位置51D运动到第二定位位置52D的同时，导向轴122相对导向槽132从第一导向位置61D运动到第二导向位置62D。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201在旋转的同时向所述外侧移动了一定距离。
因此，当定位轴121从第一定位位置51D运动到第二定位位置52D，即定位轴121沿定位槽131向靠近门侧壁21且远离门前壁22的方向移动时，其实是定位槽131相对于定位轴121向远离门侧壁21以及向靠近门前壁22的方向移动一定距离，使得第一门体201向所述内侧以及所述前侧移动。
可以理解的是，第一门体201在旋转的同时向所述内侧移动，可带动角棱23向所述内侧移动，以避免角棱23因超出参考平面M的距离太大而触碰橱柜4。第一门体201向所述前侧移动，可避免第一门体201向所述内侧移动时与箱体1的所述前端面发生摩擦。
<第二阶段>
参照图46，定位槽131还包括第三定位位置53D，第三定位位置53D较第二定位位置52D靠近门前壁22且靠近门侧壁21。导向槽132还包括第三导向位置63D，第三导向位置63D较第二导向位置62D远离门前壁22且靠近门侧壁21。
在第一门体201由所述第一角度打开至所述第二角度的过程中，定位轴121相对定位槽131从第二定位位置52D运动到第三定位位置53D，导向轴122相对导向槽132从第二导向位置62D运动到第三导向位置63D。
如前所述，定位轴121相对于箱体1固定，在第一门体201的开启过程中，定位轴121保持静止。因此，当定位轴121沿定位槽131向远离门侧壁21的方向移动时，其实是定位槽131相对于定位轴121向靠近参考平面M的方向运动，使得第一门体201向所述内侧移动了一定距离。
<第三阶段>
参照图47，定位槽131还包括第四定位位置54D，导向槽132还包括第四导向位置64D。在第一门体201由所述第二角度打开至所述第三角度的过程中，第一门体201仅进行旋转运动，也就是说定位轴121在定位槽131内的位置不变，即第四定位位置54D即为第三定位位置53D。第一门体201以定位轴121为圆心进行旋转，导向轴122相对导向槽132从第三导向位置63D沿圆弧运动至第四导向位置64D。
<第四阶段>
参照图48，定位槽131还包括第五定位位置55D，第五定位位置55D较第四定位位置54D(即第三定位位置53D)靠近门前壁22且靠近门侧壁21。导向槽132还包括第五导向位置65D，第五导向位置65D较第四导向位置64D靠近门前壁22且靠近门侧壁21。
在第一门体201由所述第三角度打开至所述最大打开角度(即所述第五角度)的过程中，定位轴121相对定位槽131从第四定位位置54D运动到第五定位位置55D，导向轴122相对导向槽132从第四导向位置64D运动到第五导向位置65D。
需要说明的是，在以上几种运动轨迹(包括第一运动轨迹至第五运动轨迹)的描述中，“第一角度”、“第二角度”等仅是为了区分每种运动轨迹下门体2开启角度的变化。“第一定位位置”、“第二定位位置”等仅是为了区分每种运动轨迹下定位轴121相对定位槽131的位置的变化。“第一导向位置”、“第二导向位置”等仅是为了区分每种运动轨迹下导向轴122相对导向槽131的位置的变化。不同运动轨迹下的相同代号“第一角度”、“第一定位位置”、“第一导向位置”等可以不相同。例如，第一运动轨迹下的第一角度和第二运动轨迹下的第一角度可以不相同。
以上几种运动轨迹仅是所述双轴铰链的部分实施例，本公开的旋停机构7所使用的双轴铰链不限于上述形式的双轴铰链，只要能实现门体2的旋停，均应在本公开的保护范围内。
以下，将以旋停机构7设置在第一铰链组件100中为例，结合上述的几种铰链轴的运动轨迹，对第一门体201在打开过程中的旋停进行介绍。可以理解的是，旋停机构7还可以是设置在第二铰链组件200、第三铰链组件300和/或第四铰链组件400中，均可以实现门体2的旋停，本公开对此不再赘述。
在一些实施例中，旋停机构7的弹性柱塞71设置在定位轴121中，限位凹部72设置在定位槽131中的第一旋停位置处，或/和，弹性柱塞71设置在导向轴122中，且限位凹部72设置在导向槽132中的第一旋停位置处，以使得第一门体201在处于关闭状态时旋停。
例如，在第一运动轨迹中，当第一门体201关闭时，定位轴121位于定位槽131的第 一定位位置51，导向轴122位于导向槽132的第一导向位置61。那么，第一定位位置51即为定位槽131的第一旋停位置，第一导向位置61即为导向槽132的第一旋停位置。
以此类推，当第一门体201处于关闭状态时，第二运动轨迹、第三运动轨迹、第四运动轨迹与第五运动轨迹中的第一定位位置和第一导向位置为第一旋停位置。
可以理解的是，将限位凹部72设置在第一铰链槽组130中的第一旋停位置处，使得第一门体201在关闭时旋停，从而可以避免因第一门体201关闭不严而导致的冰箱1000内的冷量泄露。
在一些实施例中，旋停机构7的弹性柱塞71设置在定位轴121中，限位凹部72设置在定位槽131中的第三旋停位置处，或/和，弹性柱塞71设置在导向轴122中，且限位凹部72设置在导向槽132中的第三旋停位置处，以使得第一门体201在处于第三角度(即90°)时旋停。
例如，在第一运动轨迹中，当第一门体201处于第三角度时，定位轴121位于第四定位位置54，导向轴122位于第四导向位置64。那么，第四定位位置54即为定位槽131的第三旋停位置，第四导向位置64即为导向槽132的第三旋停位置。
以此类推，当第一门体201处于第三角度时，第二运动轨迹、第三运动轨迹、第四运动轨迹与第五运动轨迹中的第四定位位置和第四导向位置为第三旋停位置。
旋停机构7设置在门体2的第三角度位置处，使得门体2在第三角度位置处旋停，避免门体2自动关闭而影响用户取放食物，又可以避免门体2碰撞橱柜4。
在一些实施例中，旋停机构7的弹性柱塞71设置在定位轴121中，限位凹部72设置在定位槽131的第四旋停位置处，或/和，弹性柱塞71设置在导向轴122中，且限位凹部72设置在导向槽132的第四旋停位置处，以使得第一门体201在打开至所述第四角度时旋停。
例如，在第一运动轨迹中，当门体2打开至第四角度时，定位轴121位于第五定位位置55，导向轴122位于第五导向位置65。那么，第五定位位置55即为定位槽131的第四旋停位置，第五导向位置65即为导向槽132的第四旋停位置。
以此类推，第二运动轨迹以及第三运动轨迹与第一运动轨迹相同，在此不做赘述。
旋停机构7设置在门体2的第四旋停位置处，使得门体2可以在打开至所述第四角度时旋停，从而可以避免门体2因自动关闭而影响用户取放食物，且可以避免门体2因惯性而继续打开，与橱柜4发生碰撞。
在一些实施例中，旋停机构7的弹性柱塞71设置在定位轴121中，限位凹部72设置在定位槽131的第五旋停位置处，或/和，弹性柱塞71设置在导向轴122中，且限位凹部72设置在导向槽132的第五旋停位置处，以使得第一门体201在打开至所述第五角度时旋停。
例如，在第一运动轨迹中，当第一门体201打开至所述第五角度时，定位轴121位于第六定位位置56，导向轴122位于第六导向位置66。那么，第六定位位置56即为定位槽131的第五旋停位置，第六导向位置66即为导向槽132的第五旋停位置。
以此类推，第二运动轨迹以及第三运动轨迹与第一运动轨迹相同，在此不做赘述。
在第五运动轨迹中，当第一门体201打开至所述第五角度时，定位轴121位于第五定位位置55D，导向轴122位于第五导向位置65D。那么，第五定位位置55D即为定位槽131的第五旋停位置，第五导向位置65D即为导向槽132的第五旋停位置。
可以理解的是，将限位凹部72设置在第五旋停位置处，使得门体2可在打开至所述第五角度时旋停，从而可以避免门体2因自动关闭而影响用户取放食物。
在一些实施例中，弹性柱塞71连接定位轴121，限位凹部72设置在定位槽131中的过渡点处。过渡点为定位轴121在定位槽131中运动趋势发生变化的位置点。
例如，在第二运动轨迹、第三运动轨迹和第四运动轨迹中，第一槽段和第二槽段的连接处为定位槽131的过渡点(即，第一过渡点)。例如，在第四运动轨迹中，第三槽段503C 和第一槽段501C的连接处也为定位槽131的过渡点(即，第二过渡点)。
在一些实施例中，所述铰链轴组与所述铰链槽组之间预留有安装间隙，以避免因装配误差造成的门体2运动卡滞及所述铰链轴组与所述铰链槽组之间的磨损。
例如，当第一门体201通过第一铰链组件100和第二铰链组件200装配在箱体1的前端时，易产生装配误差，造成第一门体201运动卡滞，导致铰链槽组(包括第一铰链槽组130和第二铰链槽组230)磨损。
在一些实施例中，导向轴122与导向槽132之间的第一预留间隙为0.1mm至0.2mm之间的任一值，例如，导向轴122与导向槽132之间的第一预留间隙为0.1mm、0.15mm或0.2mm。定位轴121与定位槽131之间的第二预留间隙为0mm至0.1mm之间的任一值，例如，定位轴121与定位槽131之间的第二预留间隙为0mm、0.05mm或0.1mm。
需要说明的是，当所述预留间隙过大时(如，第一预留间隙大于0.2mm，或第二预留间隙大于0.1mm)，门体2在打开的过程中易发生晃动；当所述预留间隙过小时(如，第一预留间隙小于0.1mm)，门体2在打开的过程中会发生运动卡滞，且会增加所述铰链轴组与所述铰链槽组之间的磨损，降低所述铰链轴组的使用寿命。
可以理解的是，当定位轴121运动至定位槽131的过渡点时，运动曲线趋势会发生变化且过渡部分会出现圆角，造成门体2在打开时发生晃动，影响开门手感。因此，通过将弹性柱塞71设置在定位轴121中，将限位凹部72设置在定位槽131的过渡点处，使第一门体201在打开至定位轴121位于所述过渡点时旋停，可以减少第一门体201在打开时发生晃动，有利于提高用户开门时的手感。
在一些实施例中，限位凹部72设置在第一铰链槽组130中的变速点处。所述变速点为第一铰链轴组120在第一铰链槽组130中运动速度突变的位置点。
例如，在第五运动轨迹中，在第一门体201由第一角度打开至第二角度的过程中，第一门体201在旋转的同时向所述内侧移动。在第一门体201由第二角度打开至第三角度的过程中，第一门体201以定位轴121为旋转轴进行旋转运动，而不发生横向移动。在第一门体201由第三角度打开至第四角度的过程中，第一门体201在旋转的同时向所述内侧移动。也就是说，在第一门体201从第一角度打开至第四角度的过程中，会出现两次运动速度突变。也就是说，定位轴121相对于定位槽131运动至第三定位位置53时发生运动速度突变，第三定位位置53为变速点。
在定位轴121的运动从相对于定位槽131的旋转运动变为相对于定位槽131的旋转和位移运动的过程中，或是在定位轴121的运动从相对于定位槽131的旋转和位移运动变为相对于定位槽131的旋转运动的过程中，定位轴121位移运动的速度突然地变为0。可以理解的是，速度的变化会产生加速度，而加速度会产生力。加速度所产生的力被定位槽131的侧壁所承受抵消，造成定位轴121和定位槽131的磨损，长时间使用后，定位轴121与定位槽131之间的间隙会因磨损增大，导致第一门体201在打开至定位轴121位于所述变速点处时发生晃动或卡死。
因此，通过将弹性柱塞71设置在定位轴121中，限位凹部72设置在定位槽131的第三定位位置53(即，变速点)处，可以使速度突变产生的力被旋停机构7所抵挡，从而减少定位轴121和定位槽131所受的力。同时，由于定位轴121的位置不变，通过限位凸部713和限位凹部72抵挡速度突变力，有利于提高门体2旋转运动的稳定性。
