Description

一种改良的冰箱铰链 技术领域
本发明涉及一种铰链的传动部件，具体说是一种改良的冰箱铰链。
 背景技术
冰箱铰链是目前最为常用的冰箱门体转动打开用连接件，为了实现冰箱门体在打开或关闭后能与冰箱柜体之间具备良好的闭合性能，现有的冰箱铰链通常会采用六连杆传动机构。然而，目前的冰箱铰链存在以下缺点：1.弹性缓冲器设置于后传动臂内，由铰接座上的凸台推动工作，后传动臂转动时，凸台的转轴始终处于固定状态，从而顶压弹簧时使弹簧受径向应力影响，容易出现弹簧的径向形变，而且受力不均；2.定位片与固定座都是分离式设置，固定座通过定位片才能固定于冰箱框体上，其不但装配工序多而造成装配效率低，而且难以保证装配强度，而且可能由于误差产生松动，影响使用体现；3.铰链座转动的力臂较少，导致冰箱门体转动所需的推力较大，不便于操作，铰链内部的连接基点较多，容易导致水汽、污垢等积聚。因此，传统的冰箱铰链仍然有待于进一步改善。
 技术问题
本发明的目的在于克服现有技术的不足，提供一种可将圆周运动转换成直线缓冲运动，性能稳定可靠，受力均匀，结构简单合理，装配效率高，装配强度大，结构稳固可靠，开关所需的推力小，且可有效防止水汽、污垢等积聚的改良的冰箱铰链。

本发明的目的是这样实现的：一种改良的冰箱铰链，包括固定座和铰链座，及设置于固定座与铰链座之间的铰链组件；其特征在于：所述铰链组件包括第一传动臂、第二传动臂、后传动臂和下传动臂；第一传动臂一端铰接固定座，第一传动臂另一端铰接有缓冲头，后传动臂一端与缓冲头连接，后传动臂另一端铰接铰链座，第二传动臂一端铰接固定座，第二传动臂另一端铰接后传动臂，下传动臂一端铰接第二传动臂，下传动臂另一端铰接铰链座；第一传动臂上设置有弹性缓冲装置，缓冲头作用弹性缓冲装置的缓冲端线性缓冲；固定座上一体成型有一块以上装配板；铰链开启状态下，第二传动臂横跨在固定座与铰链座之间。
所述弹性缓冲装置包括缓冲框体、弹性件和缓冲轮，缓冲轮滑动在缓冲框体上，弹性件一端作用在缓冲框体上，另一端作用缓冲轮弹性复位滑动。
所述缓冲头设有偏心光滑的弧形面，该弧形面与缓冲轮相挤压作用，缓冲轮滚动在所述的弧形面上。
所述弹性缓冲装置的连接端铰接第一传动臂中部；第一传动臂上装配有第一销轴，弹性缓冲装置的缓冲端支承于第一销轴上。
所述装配板往外延伸于固定座侧壁，装配板上设有一个以上固定部，以便固定装配固定座。
所述装配板的装配面a和/或固定座的装配面b上设置有防滑垫或防滑齿。
所述下传动臂与第二传动臂之间的铰接点为c，下传动臂与铰链座之间的铰接点为d，第二传动臂与后传动臂之间的铰接点为e，其中，c到d的距离小于c到e的距离。
 有益效果

1、本发明通过将弹性缓冲装置设置于第一传动臂上，使弹性缓冲装置可利用缓冲头与第一传动臂之间的定点转动产生横向位移，从而实现将圆周运动转变成直线运动的缓冲，避免了弹性件受径向应力影响出现形变，且受力不均的现象；
2、本发明通过将装配板与固定座一体式设置，不但简化了其装配工序，提高装配效率，而且有效提高整体强度，装配结构更加稳固可靠；
3.本发明通过横跨式设置第二传动臂于固定座与铰链座之间，有效的增加了铰链座转动的力臂，降低了冰箱门体开关转动所需的推力，使铰链的开关操作更加方便轻松；此外，横跨式设置还可减少铰链内部的连接基点，有效防止水汽、污垢等积聚，耐用性提高。

 本发明的最佳实施方式
下面结合附图对本发明作进一步的描述，根据图1-图4所示，本发明的改良的冰箱铰链，包括固定于冰箱框体A上的固定座1和固定于冰箱门体B上的铰链座2，及设置于固定座1与铰链座2之间的铰链组件；铰链组件包括第一传动臂3、第二传动臂4、后传动臂5和下传动臂；第一传动臂3一端铰接固定座1折弯部，第一传动臂3另一端铰接有缓冲头7，后传动臂5一端与缓冲头7固接，后传动臂5另一端铰接铰链座2中部，第二传动臂4一端铰接固定座1端部，第二传动臂4另一端铰接后传动臂5中部，下传动臂（图中未标示）一端铰接第二传动臂4中部，下传动臂另一端铰接铰链座2端部；第一传动臂3上铰接有弹性缓冲装置6，缓冲头7定点转动作用弹性缓冲装置6的缓冲端线性缓冲；固定座1上一体成型有两装配板9；铰链开启状态下，第二传动臂4横跨在固定座1与铰链座2之间。
本结构的弹性缓冲装置6可利用缓冲头7与第一传动臂3之间的定点转动产生横向位移，从而实现将圆周运动转变成直线运动的缓冲，避免了弹性缓冲装置6中的弹性件62受径向应力影响出现形变，且受力不均的现象；通过将装配板9与固定座1一体式设置，不但简化了其装配工序，提高装配效率，而且有效提高整体强度，装配结构更加稳固可靠；通过横跨式设置第二传动臂4于固定座1与铰链座2之间，有效的增加了铰链座2转动的力臂，降低了冰箱门体B开关转动所需的推力，使铰链的开关操作更加方便轻松，还可减少铰链内部的连接基点，有效防止水汽、污垢等积聚，耐用性提高。
弹性缓冲装置6包括缓冲框体61、弹性件62、缓冲轮63和推动部件64；缓冲框体61的缓冲端上设有缓冲滑槽611，缓冲轮63两端伸入缓冲滑槽611内，以滑动在缓冲框体61上；弹性件62为螺旋弹簧，其一端作用在缓冲框体61的连接端，另一端通过推动部件64作用缓冲轮63弹性复位滑动，期间缓冲轮63可自由滚动；为避免弹性件62直接作用在缓冲轮63上，影响其滚动，因此设置有推动部件64，推动部件64作用在缓冲轮63的转轴上，避免了对其的影响。
缓冲头7表面设有偏心光滑的弧形面，该弧形面具有偏心的特性，其与缓冲轮63相挤压作用，且缓冲轮63滚动在所述的弧形面上，滚动的同时又可产生缓冲效果，其可有效减小彼此之间的摩擦，使缓冲更加顺畅，而且有静音效果。
弹性缓冲装置6的连接端铰接第一传动臂3中部；第一传动臂3端部装配有第一销轴10，弹性缓冲装置6的缓冲端支承于第一销轴10上，弹性缓冲装置6的缓冲端置于第一销轴10与第一传动臂3内顶壁之间，结构紧凑可靠，整体性更强。
固定座1呈L形设置，其折弯处设有第一轴孔11，第一轴孔11内设置有第二销轴111，第一传动臂3通过第二销轴111铰接固定座1，其利用第二销轴111实现了铰接，结构简单合理。
装配板9往外延伸于固定座1两侧壁，装配板9上设有一个固定部91，以便固定装配固定座1。固定部91为通孔，其装配有紧固单元14，该紧固单元14可以是螺钉、铆钉或其他可实现固定座1与冰箱框体A固定连接的零件。
固定座1呈L形，装配板9设置于一侧的折弯边上，在确保装配稳固的前提下，有效减少装配工序，提高装配效率。此外，为进一步提高稳定性，防止固定座1移位，装配板9的装配面a上可增设防滑垫12（参见图5）或防滑齿13（参见图6）。
下传动臂与第二传动臂4之间的铰接点为c，下传动臂与铰链座2之间的铰接点为d，第二传动臂4与后传动臂5之间的铰接点为e，其中，c到d的距离小于c到e的距离，该距离关系可确保铰链在开启状态下，第二传动臂4的一端部始终在铰链座2内，进一步实现第二传动臂4的横跨式设置。
上述具体实施例仅为本发明效果较好的具体实施方式，凡与本结构相同或等同的铰链的摇杆传动机构，均在本申请的保护范围内。
