Description

缓冲组件及其铰链 技术领域
本发明涉及一种缓冲组件及其铰链。
背景技术
在门铰链中，阻尼器(油缸)设置在外壳组件中并能够在外壳组件中定向移动。因门铰链的尺寸大小不一，因此需要加工不同尺寸大小的阻尼器来满足不同尺寸大小的阻尼器(油缸)。
然而阻尼器的加工工艺较为繁琐且工艺要求高，因此当需要加工不同尺寸大小的阻尼器时，阻尼器加工设备要求高且制作材料要求高，从而导致阻尼器的加工成本高、生产效率低；同时当阻尼器(油缸)或铰链外壳组件中一个存在尺寸偏差时，均会影响阻尼器的正常使用。

其中所述缓冲组件包括阻尼器7和阻尼器套8；所述阻尼器7套设在所述阻尼器套8内；所述阻尼器套8设置在所述外壳组件9内；所述阻尼器套8通过驱动部101驱动在所述外壳组件9内定向移动；所述缓冲组件的一端抵靠于扭力弹簧6，从而使阻尼器缓冲闭合及复位。
也就是说阻尼器套内设有阻尼器的安装空腔，且能够限定阻尼器(活塞杆或)
需要说明的是，所述阻尼器套可以采用一体成型，也亦可以采用组装成型，如图*所示，所述阻尼器套采用两个半套结构组装而成，两个半套结构的加工工艺相对简单，可以降低生产制造成本。
如图31、32所示，所述扭力弹簧6转动固定于所述第一转轴4上，所述扭力弹簧的另一端61抵靠或固定于第二转轴5上，所述扭力弹簧的另一端62抵靠或固定于连接件10。
因此，所述扭力弹簧6套设在所述第一转轴4上；所述扭力弹簧6一端抵靠或固定在所述外壳组件9或第二转轴5上；所述扭力弹簧6另一端抵靠或固定在所述U型转轴2或连接件3上。这几种方案之间的组合均属于本发明的保护范围，在此不展开详细阐述。
