Description

一种用于冰箱的下铰链组件及冰箱
本申请要求了申请日为2022年09月28日，申请号为202211194055.1，发明名称为“一种用于冰箱的下铰链组件及冰箱”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及家电领域，特别是涉及一种用于冰箱的下铰链组件及冰箱。
背景技术
现在大多数冰箱产品都具有可以调节的下铰链，通过调节下铰链，以改善冰箱在长时间的使用后所造成的两扇门高度不平的问题。但是由于轴套自身的结构特点，调节后的轴套容易发生倾斜松动，产生噪音。此外，冰箱倾斜后，轴套由于一直受到铰链挤压，容易折损并且很难调节。
现有轴套与铰链板的固定方式是：在轴套上成型一个很长的柱，通过该长柱伸入铰链板的铰链孔处，实现固定。由于轴套为注塑件，长柱的顶端与末端存在很大的直径差，因此会造成长柱与铰链孔配合晃动的问题，从而使开关门产生噪音。
现有的轴套配合方式为：上下轴套的凸台与凹槽紧密配合。门体旋转过程中，当上轴套的凸台落入下轴套的凹槽时，由于上下轴套的配合面过多，上下轴套的接触面会产生撞击，造成噪音。
发明内容
本发明的一个目的是要提供一种解决上述任一技术问题的用于冰箱的下铰链组件及冰箱。
本发明一个进一步的目的是要减少开关门过程中的噪音。
本发明另一个进一步的目的是要增强下铰链结构的稳定性。
特别地，本发明提供了一种用于冰箱的下铰链组件，该下铰链组件包括：
铰链板，与冰箱箱体连接；
铰链轴，与铰链板连接；
铰链轴套，套设于铰链轴上，并与铰链板连接；
门体轴套，可枢转地套设于铰链轴上，并位于铰链轴套的上方，铰链轴套与门体轴套配合以使得门体相对于箱体可转动地连接；
铰链轴套沿铰链轴周向间隔设置有多个上凸部，门体轴套沿铰链轴周向间隔设置有多个下凹部，部分上凸部与其对应的下凹部间隔配合，以降低旋转过程中的噪音。
进一步地，铰链轴套还包括：
铰链轴套主体板，设置于所述铰链板上方，并与所述铰链板连接；
轴套部，设置于主体板的一端，并开设有通孔，铰链轴从通孔伸出，以使得铰链轴套套设于铰链轴上；
