具体实施方式
本领域的普通技术人员应当理解，可以对本公开实施例的技术方案进行修改或者等同替换，而不脱离本公开实施例技术方案的精神和范围，均应涵盖在本公开的权利要求范围当中。
本公开实施例提供一种铰链装置，包括转动部分和同动部分；
所述转动部分包括导槽座、第一支撑板、第二支撑板、第一连接板和第二连接板；所述导槽座设置有第一非圆弧导槽、第二非圆弧导槽、第一圆弧导槽和第二圆弧导槽；所述第一支撑板设置有与所述第一非圆弧导槽转动配合的第一非圆弧转动部，所述第二支撑板设置有与所述第二非圆弧导槽转动配合的第二非圆弧转动部，所述第一连接板设置有与所述第一圆弧导槽转动配合的第一圆弧转动部，所述第二连接板设置有与所述第二圆弧导槽转动配合的第二圆弧转动部；所述第一连接板以可滑动方式连接在所述第一支撑板上，所述第二连接板以可滑动方式连接在所述第二支撑板上；
