Description

铰链结构
技术领域
本发明涉及一种铰链结构，尤其涉及一种适用于电子装置的铰链结构。
背景技术
目前，市场上常见的电子设备，如笔记本电脑、个人数字助理(Personal DigitalAssistant，PDA)、手机、电子辞典一般为折叠式，其包括本体和盖体。本体和盖体通过一铰链结构铰接在一起，从而实现盖体相对于本体打开或闭合。
一种铰链结构，用以连接电子设备的本体和盖体，其包括一个转轴以及依次套设于转轴上的一个固定支架、一个转动支架、多个弹性件及一个紧固件。固定支架与本体固定连接，并可相对转轴转动。转动支架与盖体固定连接，并可随该转轴一起转动。弹性件抵持于转动支架上，从而使得固定支架与转动支架始终紧密抵靠。盖体相对本体旋转时，转动支架与固定支架之间相互摩擦而形成摩擦力矩，从而实现盖体相对于本体旋转到任意位置时定位。
然而，上述铰链结构较为复杂，元件数量较多，需要耗费较多的材料成本和装配时间。
发明内容
鉴于上述状况，有必要提供一种结构简单的铰链结构。
一种铰链结构，包括第一支架和第二支架。第一支架具有卷绕部，卷绕部具有空腔。第二支架具有卷绕状枢接部。卷绕状枢接部可转动地装配于第一支架的卷绕部的空腔内。
该铰链结构的构成元件较少，结构较为简单。
附图说明
图1是本发明实施例一的铰链结构的立体组装图。
图2是图1所示铰链结构的分解图。
图3是图1所示铰链结构沿III-III线的剖视图。
图4是本发明实施例二的铰链结构的剖视图。
图5是本发明实施例三的铰链结构的剖视图。
具体实施方式
本发明的多个实施例的铰链结构适用于翻盖式电子装置。在本实施例中，以应用在笔记本电脑上的铰链结构为例加以说明。
请同时参阅图1和图2，本实施例一的铰链结构20包括两个第一支架21和一个第二支架23。
第一支架21由具有弹性的金属材料制成，优选为由耐磨且抗疲劳的不锈钢材料制成。第一支架21包括一定位板211和由定位板211一端逆时针卷绕形成的卷绕部213。定位板211上设有多个安装孔2111。第一支架21与笔记本电脑的本体(图未示)相固定，如可通过多个螺钉(图未示)等锁固元件相应装配于多个安装孔2111使第一支架21与笔记本电脑的本体相固定。卷绕部213具有圆弧形的内表面2131。内表面2131环绕形成一近似圆柱形的空腔2133。
第二支架23由具有弹性的金属材料制成，优选为由耐磨且抗疲劳的不锈钢材料制成。第二支架23包括一固定板231和由固定板231一端顺时针卷绕后向固定板231两侧延伸形成的两个卷绕状枢接部233。固定板231上设有多个安装孔2311。第二支架23与笔记本电脑的盖体(图未示)相固定，如可通过多个螺钉(图未示)等锁固元件相应装配于多个安装孔2311使第二支架23与笔记本电脑的盖体相固定。枢接部233具有圆弧形的外表面2331。组装前，枢接部233的外径略大于卷绕部213的内径，即空腔2133的直径。
请参阅图3，组装时，只需将第二支架23的两个枢接部233可转动地装配于两个第一支架21的卷绕部213的空腔2133内即可。由于卷绕部213的空腔2133的直径略小于枢接部233的外径，因此插入空腔2133的枢接部233此时处于一个径向收缩变形的状态，并具有向外扩张的趋势。同时，具有弹性的卷绕部213此时处于一个径向扩张变形的状态，并具有向内收缩的趋势。由此导致枢接部233的外表面2331与卷绕部213的内表面2131之间形成较大的挤压力。
当笔记本电脑的盖体相对本体旋转时，第二支架23的枢接部233在第一支架21的空腔2133内旋转。枢接部233的外表面2331与卷绕部213的内表面2131之间相互摩擦，由此产生的摩擦力矩使盖体旋转至任意位置后定位。
本实施例一的铰链结构20的构成元件较少，结构较为简单。在盖体相对本体开启与闭合的过程中，枢接部233的外表面2331始终与卷绕部213的内表面2131相互抵持，由于二者之间的相对摩擦面积没有发生变化，因此由摩擦力转化的扭力大小也不变，从而确保盖体始终处于受力平衡状态，防止盖体闭合时突然下坠而对本体造成冲击。
可以理解，第二支架23的枢接部233也可为一个，此时第一支架21也相应为一个。
枢接部233的卷绕方向与卷绕部213的卷绕方向也可相同。
本实施例一中，第一支架21的卷绕部213与定位板211为一体成型，但是卷绕部213与定位板211也可以是分别成型后固定于一体。卷绕部213和定位板211也可由刚性材料制成。
本实施例一中，第二支架23的枢接部233与固定板231为一体成型，但是枢接部233与固定板231也可以是分别成型后固定于一体。枢接部233和固定板231也可由刚性材料制成。
请参阅图4，本实施二的铰链结构30与本实施一的铰链结构20结构相似，其包括第一支架31和第二支架33。第一支架31具有卷绕部313，第二支架33具有枢接部333。其不同之处在于，卷绕部313的内表面3131上开设有多个方形凹槽3133。凹槽3133具有保存润滑油的功能，可减小卷绕部313和枢接部333之间的磨损，进一步延长铰链结构30的使用寿命。可以理解，凹槽3133的形状也不限于方形，例如可为半圆形、楔形等。凹槽3133既可以开设在卷绕部313的内表面3131上，也可以开设在枢接部333的外表面3331上，还可同时开设在内表面3131和外表面3331上。
请参阅图5，本实施三的铰链结构40与本实施一的铰链结构20结构相似，其包括第一支架41和第二支架43。第一支架41具有卷绕部413，第二支架43具有枢接部433。其不同之处在于，卷绕部413的内表面4131对枢接部433的外表面4331之间设有一具有弹性的耐磨贴片45。耐磨贴片45可减小卷绕部413和枢接部433之间的磨损，进一步延长铰链结构40的使用寿命。可以理解，耐磨贴片45的数量也可为多个。
另外，本领域技术人员还可以在本发明精神内作其它变化，当然，这些依据本发明精神所作的变化，都包含在本发明要求保护的范围之内。
