Description

一种支架结构
本申请是以申请号为202022655750.6、申请日为2020年11月17日的中国专利申请为基础，并主张其优先权，该申请的全部内容在此作为整体引入本申请中。
技术领域
本申请属于电子产品支架技术领域，特别涉及一种支架结构。
背景技术
目前，电子产品设备被广泛应用在各个领域中，笔记本电脑、平板电脑等电子设备由于体积小、重量轻，具有良好的便携性而受到人们的喜爱，随着科技的发展，笔记本电脑、平板电脑等电子设备成为人们生活中不可或缺的电子产品，但在工作学习的过程中，由于工作学习场所的限制，通常需要将笔记本电脑、平板电脑等电子设备通过支架支撑起来。
现在市场上有很多可升降的支架结构来对笔记本电脑、平板电脑等电子设备形成支撑，这类支架很多都是采用升降杆进行升降，气弹簧提供支架的上升动力，在上升的过程中需要随时停止，这就需要锁紧机构来使支架上升或者下降的停止，现有的锁紧机构零部件比较多，而很多锁紧机构是设置在支架桌的底框的位置，操作十分不方便，无法随心所欲地锁紧定位，另外，现有的支架桌的锁紧多是利用零部件之间的摩擦或者挤压来进行锁紧，长时间使用或者受到重压时，容易出现解锁松动的情况，使用的时候就不安全，会影响支架的使用寿命；还有一种支架是采用阻尼转轴连接支撑杆，根据阻尼转轴的阻尼将笔记本电脑、平板电脑等电子设备支撑在支架上，但是这种支架通常在支架撑起或者折叠时，其阻尼力都是相同的，便会造成在使用时将支架撑起需要较大的力克服阻尼转轴的力，使用极其不便，体验较差。
申请内容
本申请目的在于为克服现有的技术缺陷，提供一种支架结构，在撑起支架上升时需要的力非常小，在折叠支架下降时需要的力较大，保证了在撑起支架后放置物品不易下降，对物品形成更好的支撑。
为了解决上述技术问题，本申请提供了一种支架结构，包括底座、设于所述底座上方的面板和用于连接所述底座和面板的转动臂，所述底座通过第一转轴与所述转动臂的一端转动连接，所述面板通过第二转轴与所述转动臂的另一端转动连接，所述第一转轴和第二转轴上分别设有与所述转动臂的两端固定连接的第一单向轴承和第二单向轴承，且所述第一单向轴承与第二单向轴承的转动方向相反。
进一步的，所述底座的上端固定设有第一转动座，所述转动臂的一端设有第一安装孔，所述第一转轴转动设于所述第一转动座上，所述第一单向轴承设于所述第一安装孔内并与所述转动臂固定连接。
进一步的，所述第一转动座上设有用于限制所述转动臂的一端转动位置的第一限位螺钉。
进一步的，所述第一转轴包括第一中心轴和套设于所述第一中心轴的一端并与所述第一转动座固定连接的第一阻尼转动组件，所述第一单向轴承套设于所述第一中心轴的另一端。
进一步的，所述第一阻尼转动组件包括与所述第一中心轴套装固定的第一垫片组、套设于所述第一中心轴上并与所述第一垫片组相互摩擦的第一转动套以及螺纹套装于所述第一中心轴上并向内顶紧所述转动套和垫片的第一锁紧件，所述第一转动套与所述第一转动座固定连接。
进一步的，所述面板的下端固定设有第二转动座，所述转动臂的另一端设有第二安装孔，所述第二转轴转动设于所述第二转动座上，所述第二单向轴承设于所述第二安装孔内并与所述转动臂固定连接。
进一步的，所述第二转动座上设有用于限制所述转动臂的另一端转动位置的第二限位螺钉。
进一步的，所述第二转轴包括第二中心轴和套设于所述第二中心轴上并与所述第二转动座固定连接的第二阻尼转动组件，所述第二单向轴承套设于所述第二中心轴的另一端。
进一步的，所述第二阻尼转动组件包括与所述第二中心轴固定连接的第二垫片组、套设于所述第二中心轴上并与所述第二垫片组相互摩擦的第二转动套以及螺纹套装于所述第二中心轴上并向内顶紧所述转动套和垫片的第二锁紧件，所述第二转动套与所述第二转动座固定连接。
进一步的，所述底座的下端设有防滑垫，所述面板的上端设有缓冲垫，所述面板的一端向上凸起设有支托部。
本申请具有以下有益效果：
本申请由于第一转轴和第二转轴上分别设有与转动臂的两端固定连接的且转动方向相反的第一单向轴承和第二单向轴承，当需要升高面板时，第一单向轴承绕第一转轴的转动方向和第二单向轴承绕第二转轴的转动方向相反，此时升高面板时阻尼最小，趋近于零，用非常小的力便能够撑起支架，当需要降低面板时，第一单向轴承绕第一转轴的转动方向改变并锁死，第二单向轴承绕第二转轴的转动方向改变并锁死，降低面板时阻尼最大，为第一转轴和第二转轴本身转动的阻尼，当面板上放置物品时，支架结构能够对物品形成更好的支撑，保证了在撑起支架后放置物品不易下降。
本申请附加的方面和优点将在下面的描述中部分给出，这些将从下面的描述中变得明显，或通过本申请的实践了解到。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例；基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例
如图1-5所示，本实施例所示的支架结构，包括底座3、设于底座3上方的面板4和用于连接底座3和面板4的转动臂5，底座3通过第一转轴1与转动臂5的下端转动连接，面板4通过第二转轴2与转动臂5的上端转动连接，第一转轴1和第二转轴2上分别设有与转动臂5的两端固定连接的第一单向轴承11和第二单向轴承21，且第一单向轴承11与第二单向轴承21的转动方向相反，第一单向轴承11可绕第一转轴1正转，第二单向轴承21可绕第二转轴2反转，第一单向轴承11绕第一转轴1反转时锁死，第二单向轴承21绕第二转轴2正转时锁死；在上述结构中，由于第一单向轴承11可绕第一转轴1正转，第二单向轴承21可绕第二转轴2反转，且第一单向轴承11和第二单向轴承21分别与转动臂5的两端固定连接，当需要升高面板4时，第一单向轴承11绕第一转轴1正转，第二单向轴承21绕第二转轴2反转，故而当升高面板4时阻尼最小，趋近于零，实现了用非常小的力便能够撑起支架，当需要降低面板4时，第一单向轴承11绕第一转轴1反转锁死，第二单向轴承21绕第二转轴2正转锁死，故而当降低面板4时阻尼为第一转轴1和第二转轴2本身转动的阻尼，实现了需要用非常大的力才能够合起支架，从而实现了当物品放置在面板4上时，支架能够对物品形成更好的支撑，物品不易下压支架造成支架下降。
具体的，在底座3的上端固定设有第一转动座31，在第一转动座31的上端设有第一转动孔32，在转动臂5的下端设有第一安装孔51，第一转动孔32和第一安装孔51相对应，第一转轴1转动设于第一转动孔32内，第一单向轴承11固定设于第一安装孔51内，在第一安装孔51外部还设有用于盖住第一安装孔51的第一饰片53；通过第一转轴1将转动臂5和第一转动座31转动连接，转动臂5的下端能够绕第一转轴1转动。
具体的，在第一转动座31上设有第一限位螺钉33，第一限位螺钉33设置在第一转动座31的内侧，第一限位螺钉33能够限制转动臂5相对于底座3的转动角度，防止转动臂5转动幅度过大，造成支架承载物品时发生不稳定的情况。
具体的，第一转轴1包括第一中心轴10和套设在第一中心轴10的一端并与第一转动孔32固定连接的第一阻尼转动组件，第一单向轴承11套设在第一中心轴10的另一端，第一单向轴承11可绕第一中心轴10正转，第一单向轴承11不可绕第一中心轴10反转。
