Description

用于笔记本电脑的转轴机构 技术领域
本公开涉及笔记本电脑技术领域，例如涉及用于笔记本电脑的转轴机构。
背景技术
随着科技的发展，不同的电子产品不断的出现，给人们的生活带来巨大的改变，特别是电脑的使用改变了人们的生活方式。随着材料科学的发展和体积更小的集成芯片出现，电脑已衍变成一种体积小，厚度薄，重量轻且易于随身携带的笔记本电脑。而笔记本电脑以掀盖式居多，为符合薄、小与重量轻等设计要求，一般都设计成由底座和和上盖构成，底座包括主机本体和键盘，上盖包括显示屏和盖体。而笔记本电脑在不使用状态时，上盖通常盖合在底座上，在使用时须将上盖向上掀开至适当角度，才能对笔记本电脑进行操作使用。
笔记本电脑转轴一般是在转轴的枢轴上直接设有环形导油凹槽，同时转轴采用锌合金作为材料，这样的设计存在以下缺点：采用此结构的笔记本电脑转轴，散热较慢，会出现局部发热现象，并导致油槽中的润滑油容易熔化，这样对油槽中的润滑油熔点要求较高，在枢轴上设有环形导油凹槽，不利于润滑油储存，这样在掀起和关闭笔记本电脑上盖时，可能导致漏油情况出现，同时在枢轴上设有环形导油凹槽也不易形成均匀的油膜。
