背景技术
通常情况下，冰箱和门体之间都是通过一个固定的铰链件来实现相对运动，门体绕一个固定的轴心转动，导致门体的开闭自由度会大大受限，即无法自由控制门体运动轨迹以适应不同的应用场景。
随着社会的进步，人们生活水平的提高，对冰箱在家庭的摆放位置与摆放方式越来越被普通用户看重，而针对目前的家装风格，部分家庭追求风格一体化，就需要把冰箱放入橱柜中，构成所谓的嵌入式冰箱，门体仅绕一个固定的轴心转动的冰箱难以适应这种嵌入式应用场景，即，在开门时，门体与橱柜之间会产生干涉。
现有的部分嵌入式冰箱在箱体与门体之间采用双轴双槽结构相连接，以在门体旋转打开的同时驱动门体按预设轨迹平移，避免门体与橱柜之间产生干涉。但是，门体在打开过程中无法实现悬停功能；同时，关门时门体也易出现反弹，发生小角度关门不严的问题，影响用户的使用体验感。

请参图1-图12所示，为本发明第一实施方式中的下铰链组件3及具有该下铰链组件3的嵌入式冰箱100。所述嵌入式冰箱100用以嵌入橱柜200内，当然，并不以此为限，所述嵌入式冰箱100也可以嵌入墙体内等。
所述嵌入式冰箱100包括箱体1、用以打开或关闭所述箱体1的门体2、将所述门体2活动连接于所述箱体1上的铰链组件。在所述门体2向远离所述箱体1的方向转动打开的过程中，所述铰链组件驱动所述门体2按预设轨迹平移，以避免所述门体2与所述橱柜200之间产生干涉。
具体地，所述铰链组件包括设于所述门体2上方的上铰链组件以及设于所述门体2下方的下铰链组件3。本发明中并不限定所述上铰链组件的具体结构，只要在所述门体2转动的过程中，所述上铰链组件与所述下铰链组件3相配合能够驱动所述门体2按预设轨迹平移即可。
结合图2-图3所示，所述下铰链组件3包括固定于箱体1上的固定铰链件31、固 定于门体2上且与所述固定铰链件31活动连接的活动铰链件32。在所述门体2转动的过程中，所述活动铰链件32与所述门体2同步运动，上述的门体2按预设轨迹平移即指所述活动铰链件32按预设轨迹平移。
进一步地，所述固定铰链件31、活动铰链件32之间具有相互配合的第一基面311、第二基面321。所述第一基面311与所述第二基面321之间设有第一轴体312、与所述第一轴体312相配合的第一槽体322、第二轴体313、与所述第二轴体313相配合的第二槽体323。在所述活动铰链件32向远离所述固定铰链件31的方向转动打开的过程中，所述第一轴体312与所述第一槽体322配合，所述第二轴体313与所述第二槽体323相配合驱动所述活动铰链件32按预设轨迹平移，带动所述门体2按预设轨迹平移。本发明中，通过双轴(第一轴体312以及第二轴体313)及双槽(第一槽体322以及第二槽体323)的配合驱动门体2转动过程中按预设轨迹运动，相较于单轴铰链，无需很高的安装精度，可大大降低设计成本以及安装难度。
本实施方式中，所述第一轴体312与所述第二轴体313均设于所述固定铰链件31上，所述第一槽体322与所述第二槽体323均设于所述活动铰链件32上。当然，并不以此为限，于其他实施方式中，所述第一轴体312与所述第二轴体313也可以均设于所述活动铰链件32上，所述第一槽体322与所述第二槽体323均设于所述固定铰链件31上。
具体地，所述固定铰链件31包括固定于所述箱体1上的铰链板314，所述第一轴体312、第二轴体313均凸设于所述铰链板314的上表面上。所述固定铰链件31还包括固定于所述铰链板314的上表面上的轴套315，所述轴套315上具有供所述第一轴体312、第二轴体313穿过的轴孔3151。在所述轴套315安装至所述铰链板314上后，所述第一轴体312、第二轴体313自所述轴孔3151向外暴露，以便使所述第一轴体312、第二轴体313能够分别与所述活动铰链件32上的第一槽体322、第二槽体323相配合，以使所述活动铰链件32活动连接至所述固定铰链件31上，且使所述活动铰链件32能够按预设轨迹平移。
上述的第一基面311即指所述轴套315朝向所述活动铰链件32的一侧，即，所述轴套315的上表面。对应地，上述的第二基面321即指所述活动铰链件32朝向所述轴套315的一侧，即所述活动铰链件32的下表面。
进一步地，所述第一基面311与所述第二基面321中的一个上设有朝向另一个突伸的止挡凸块33、另一个上设有位于所述止挡凸块33的移动路径上以与所述止挡凸块33相配合的限位引导部34。在所述止挡凸块33与所述限位引导部34相配合后，所述限位引导部34限位所述止挡凸块33，能够定位所述门体2，使所述门体2定位于预设位置处，如，使所述门体2限位于预设打开角度或者限位于关闭状态。
在所述限位引导部34限位所述止挡凸块33，能够使所述门体2限位于预设打开角度时，方便用户取放物品，针对暴力开门现象，即使开门力度克服了止挡凸块33与限位引导部34之间的悬停力度，限位引导部34的存在也会减缓门体2打开速度，对暴力开门起到缓冲作用。
在所述限位引导部34限位所述止挡凸块33，能够使所述门体2限位于关闭状态时，能够避免门体2关门后反弹，避免关门不严的问题。
于一具体实施方式中，所述止挡凸块33凸设于所述第二基面321上，所述限位引导部34设于所述第一基面311上。当然，并不以此为限，于其他实施方式中，所述止 挡凸块33凸设于所述第一基面311上，所述限位引导部34设于所述第二基面321上。
请参图2-图7所示，所述限位引导部34包括与所述止挡凸块33相配合的限位槽341，在所述活动铰链件32向远离所述固定铰链件31的方向转动打开至所述止挡凸块33啮合至所述限位槽341内后，所述活动铰链件32限位于预设打开角度。使所述门体2处于悬停状态，即所述门体2限位于所述预设打开角度，方便用户取放物品。
于一具体实施方式中，所述预设打开角度为90°。当然，并不以此为限，于其他实施方式中，所述预设打开角度也可以大于所述90°，便于用户取放物品。
具体地，所述止挡凸块33与所述限位槽341均呈弧形。使所述止挡凸块33能够较为平缓地进入或者脱离所述限位槽341，增强所述门体2转动的平稳性。
进一步地，所述限位引导部34包括导引斜面342，在所述活动铰链件32自预设关闭角度朝向所述固定铰链件31转动关闭至关闭状态时，所述止挡凸块33与所述导引斜面342相配合。在所述门体2的自重的作用下，所述止挡凸块33沿所述导引斜面342移动，使门体2转动关闭，能够起到助力关门的作用，同时，在所述门体2处于关闭状态后，所述止挡凸块33与所述导引斜面342的端部相抵持，也能够使所述门体2限位于关闭状态时，能够避免门体2关门后反弹，避免关门不严的问题。
进一步地，所述止挡凸块33具有配合斜面331，在所述活动铰链件32自预设关闭角度朝向所述固定铰链件31转动关闭至关闭状态时，所述配合斜面331与所述导引斜面342相配合，能够使所述门体2自助缓慢关闭，增强所述门体2运动的平稳性。
于一具体实施方式中，所述预设关闭角度为15°。即，在所述门体2关闭至15°时，所述止挡凸块33位于所述导引斜面342上，此时，用户松手，在门体2自重下，所述止挡凸块33沿所述导引斜面342移动，使门体2转动关闭，起到助力关门的作用。当然，并不以此为限。
可知的是，在所述门体2转动的过程中，所述门体2会同步产生平移，即，所述门体2的转动轴心并不是固定的，也会产生平移。
上述的门体2的转动轴心为虚拟轴心，即有所述第一轴体312以及所述第二轴体313共同限定的所述转动轴心。
进一步地，本实施方式中，所述限位引导部34位于所述第一基面311与所述固定铰链件31边缘相对应的位置处，即，所述限位引导部34位于所述轴套315的边缘处。对应的，所述止挡凸块33位于所述第二基面321的边缘处，即，所述止挡凸块33距所述门体2的转动轴心距离较远，使门体2转动过程中，所述止挡凸块33的移动路径几乎位于同一圆周上，从而，所述限位槽341以及所述导引斜面342几乎位于同一圆周上，能够避免所述门体2运动过程中出现卡顿点，增强所述门体2运动的顺滑性以及平稳性。
具体地，所述第一基面311上与所述止挡凸块33的移动路径对应的位置处凸设有波浪状结构3111，所述波浪状结构3111形成所述限位引导部34。在所述门体2转动的过程中，所述波浪状结构3111能够引导所述止挡凸块33移动至所述导引斜面342上，以及引导所述止挡凸块33移动至所述限位槽341内，增强所述门体2运动的顺滑性以及平稳性。
可知的是，所述波浪状结构3111成型于同一圆周上，能够避免所述门体2运动过程中出现卡顿点，增强所述门体2运动的顺滑性以及平稳性。
进一步地，所述门体2具有转动端21、与所述转动端21相对的自由端22，所述 转动端21与所述自由端22形成与前后方向相垂直的第一方向。
具体地，当所述转动端21为所述门体2的左端或右端时，所述第一方向为左右方向。
具体地，沿转动端21朝向自由端22的方向，所述第一轴体312、第二轴体313依次设置，即，所述第一轴体312相较于所述第二轴体313更靠近所述转动端21。
进一步地，结合图1、图4所示，所述箱体1具有位于所述门体2的转动端21的枢转侧11。定义自所述箱体1的中心背离所述枢转侧11的方向为第二方向X，自所述箱体1的中心朝向所述枢转侧11的方向为第三方向Y。
具体地，当所述转动端21为所述门体2的右端时，所述枢转侧11即指所述箱体1的右侧，所述第二方向X即为从右向左的方向，所述第三方向Y即为从左向右的方向。当所述转动端21为所述门体2的左端时，所述枢转侧11即指所述箱体1的左侧，所述第二方向X即为从左向右的方向，所述第三方向Y即为从右向左的方向。
具体地，结合图8-图12所示，所述第一槽体322包括初始位置A1、第一停止位置A2，所述第二槽体323包括相对设置的第一端L1、第二端L2、位于所述第一端L1与第二端L2之间且相连的第一段L3及第二段L4。结合图8所示，当所述门体2处于关闭状态时，所述第一轴体312处于初始位置A1，所述第二轴体313位于第一端L1，所述止挡凸块33抵持于所述导引斜面342上，以使所述门体2保持于关闭状态。所述第一段L3为以所述初始位置A1为圆心的圆弧。结合图9所示，当所述门体2自关闭状态开启至第一开启角度的过程中时，所述第一轴体312保持在所述初始位置A1，所述第二轴体313于所述第一段L3内运动，此时，所述门体2以位于所述初始位置A1的第一轴体312为轴心原地转动，即门体2仅转动而不产生其他方向的位移，可以有效避免因门体2某个方向的位移而导致门体2无法正常开启，如具有翻转梁的门体2，能够使翻转梁上的凸块能够脱离箱体1上的凹槽，以使所述门体2能够顺利打开。结合图10所示，当所述门体2自第一开启角度继续开启至第二开启角度的过程中时，所述第二轴体313于所述第二段L4内朝向所述第二端L2的方向运动而带动所述第一轴体312由所述初始位置A1运动至所述第一停止位置A2，此时，所述门体2转动的过程中沿第二方向X向远离所述枢转侧11的方向移动，从而避免门体2在打开过程中与周边的橱柜200或墙体等产生干涉，适用于容纳嵌入式冰箱100的空间较小的场景。
进一步地，结合图11所示，当门体2由第二开启角度继续开启至第三开启角度的过程中时，活动铰链件32与所述固定铰链件31相配合在所述门体2转动的同时驱动门体2沿所述第三方向Y朝向所述枢转侧11移动。如此，可使得门体2尽量远离箱体1，保证箱体1的开度，避免箱体1内的抽屉、搁物架等受门体2干涉而无法打开的问题。
具体地，结合图11所示，所述第一槽体322还包括位于所述初始位置A1远离所述第一停止位置A2一侧的枢转位置A3，所述第二槽体323还包括位于所述第二段L4及所述第二端L2之间的第三段L5。当所述门体2处于由第二开启角度继续开启至第三开启角度的过程中时，所述第二轴体313于所述第三段L5内运动而带动所述第一轴体312由所述第一停止位置A2运动至所述枢转位置A3。此时，所述门体2转动过程中沿所述第三方向Y朝向所述枢转侧11移动，可使得门体2尽量远离箱体1，保证箱体1的开度，避免箱体1内的抽屉、搁物架等受门体2干涉而无法打开的问题。
进一步地，当所述门体2处于由第三开启角度继续开启至最大开启角度的过程中 时，活动铰链件32与所述固定铰链件31相配合驱动门体2相对箱体1原地转动，以进一步打开门体2。
具体地，结合图12所示，所述第二槽体323还包括位于所述第三段L5与所述第二端L2之间的第四段L6，所述第四段L6为以所述枢转位置A3为圆心的圆弧槽。结合图6所示，当所述门体2处于由第三开启角度继续开启至最大开启角度的过程中时，所述第一轴体312保持在所述枢转位置A3，所述第二轴体313于所述第四段L6内运动，以使所述门体2以位于所述枢转位置A3的所述第一轴体312为轴心原地转动，以进一步打开门体2。
可以理解的，当门体2由关闭状态开启至第一开启角度的过程中时，由于是门体2相对箱体1原地转动，门体2的枢转端会沿第三方向Y朝向枢转侧11稍许凸伸出箱体1。当门体2由第一开启角度继续开启至第二开启角度的过程中时，门体2沿第二方向X的位移可以抵消门体2在整个转动过程中沿第三方向Y凸伸出箱体1的所有部分，而后当门体2由第二开启角度继续开启至第三开启角度的过程中时，门体2沿第三方向Y的位移可以使得门体2不凸伸出箱体1且尽量保证箱体1开度。
具体地，所述第一开启角度小于所述第二开启角度，所述第一开启角度为10°，第二开启角度不大于90°，第三开启角度为90°，最大开启角度大于90°。也就是说，在门体2自第一开启角度10°开启至90°的过程中，门体2先沿第二方向X产生位移，避免门体2在打开过程中与周边的橱柜200或墙体等产生干涉，而后门体2再沿第三方向Y产生位移，避免门体2阻碍箱体1内的抽屉、搁物架等的开启，最后达到之后，门体2相对箱体1原地转动而进一步打开门体2。
可知的是，在所述预设打开角度为90°的实施方式中，在所述门体2悬停于预设打开角度后，即悬停于第三开启角度后，若是需要继续增大门体2的打开角度，可进一步打开门体2，使止挡凸块33脱离限位槽341，从而，能够进一步增大门体2的打开角度至最大开启角度。
请参图13-图16所示，为本发明第二实施方式中的所述下铰链组件3a以及具有该下铰链组件3a的嵌入式冰箱100a。本发明第二实施方式中的所述下铰链组件3a与第一实施方式中的所述下铰链组件3的区别在于：所述限位引导部34a设于所述第一槽体322或者所述第二槽体323的槽口处，对应的，所述止挡凸块33靠近所述第一轴体312或所述第二轴体313设置。即，在所述限位引导部34a设于所述第一槽体322的槽口处时，所述止挡凸块33靠近所述第一轴体312设置。在所述限位引导部34a设于所述第二槽体323的槽口处时，所述止挡凸块33靠近所述第二轴体313设置。简化所述限位引导部34a的设置，简化所述下铰链组件3a的结构。
进一步地，所述第一槽体322以及所述第二槽体323的槽口具有翻边3221，所述限位引导部34a设于所述翻边3221上。具体地，在所述限位引导部34a设于所述第一槽体322的槽口处时，所述限位槽341a以及所述导引斜面342a通过凹设形成于所述翻边3221上。简化所述限位引导部34a的设置。
本发明第二实施方式中的所述下铰链组件3a与本发明第一实施方式中的所述下铰链组件3除上述区别外，其他均相同，于此，不再赘述。
综上所述，本发明中的下铰链组件3，通过在固定铰链件31与活动铰链件32之间设置相互配合的止挡凸块33以及位于所述止挡凸块33的移动路径上的限位引导部34。在所述止挡凸块33与所述限位引导部34相配合后，所述限位引导部34限位所述止挡 凸块33，能够定位所述门体2，使所述门体2限位于预设打开角度或者限位于关闭状态。
