具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
总体概述
结合参见图1至图12所示，本发明提供了一种支撑架。支撑架包括第一安装件10、弹性件20、第一连接件30、第二连接件50、第一联动件A和第二联动件C。弹性件20设置在第一安装件10上；第一联动件A沿第一预设弧形轨迹可移动地设置；第二联动件C与第一联动件A联动连接，第二联动件C沿第二预设弧形轨迹可移动地设置，第二预设弧形轨迹的半径小于或者等于第一预设弧形轨迹的半径；第一连接件30的第一端与弹性件20连接，第一连接件30的第二端与第二联动件C联动连接，第二连接件50与第一联动件A联动连接；第二安装件60，沿预设方向，第二安装件60与第一安装件10之间具有相对移动，第二安装件60与第二连接件50连接，其中，第二安装件60和第一安装件10之间发生相对移动时，第一联动件A沿第一预设弧形轨迹移动，第二联动件C沿第二预设弧形轨迹移动，第一连接件30发生移动，以带动弹性件20发生变形，第二安装件60或第一安装件10具有悬停支撑位置。
第一联动件A和/或第二联动件C为销轴。当然，也可以为滚动轮或转动轮等。
第一连接件30为绳索，支撑架还包括与第一安装件10连接的第一导向件71，绳索的一端与弹性件20连接，绳索的另一端依次绕过第一导向件71后与第二联动件C联动连接，并且第一导向件71与第一安装件10连接，通过上述设置当第二联动件C沿预设弧形轨迹移动时，绳索将拉动弹性件20使得弹性件发生形变。
第一连接件30的第二端与第二联动件C固定连接或绕过第二联动件C后与第一安装件10固定连接，第二连接件50与第一联动件A固定连接或绕过第一联动件A后与第一安装件10固定连接。
需要说明的是，第二预设弧形轨迹的半径等于第一预设弧形轨迹的半径指的是两个轨迹重合为一个轨迹。联动连接指的是联动件(包括第一联动件A和第二联动件C)能够使得与之相连的结构产生联动，起到传递运动的作用。
实施例一
在上述方案的基础上，本发明的实施例一中，如图2和图3所示，支撑架还包括与第一安装件10枢转连接的转动件40，第一联动件A和第二联动件C设置在转动件40上，第二联动件C位于转动件40和第一安装件10之间的枢转点与第一联动件A之间，第一连接件30 的第一端与弹性件20连接，第一连接件30的第二端与第二联动件C联动连接，第二连接件50与第一联动件A联动连接，转动件40能够绕转动件40与第一安装件10之间的枢转点摆动，参考图2中具体结构。
此时，第一预设弧形轨迹的半径大于第二预设弧形轨迹的半径，第一导向件71为导向轮。
第二连接件50为连接绳索，支撑架还包括与第一安装件10连接的第三导向件72，连接绳索的一端与第一联动件A联动连接，连接绳索的另一端绕过第三导向件72后连接至第二安装件60，第二安装件60和第一安装件10之间发生相对移动时，连接绳索移动，以带动弹性件20发生变形。
连接绳索的一端与第一联动件A固定连接或绕过第一联动件A后与第一安装件10固定连接，参考图2和图3，连接绳索的另一端绕过第三导向件72后连接至第二安装件60。
需要说明的是，利用第三导向件72能够使连接绳索始终处于拉紧状态，第三导向件72还能够改变作用在连接绳索上的力的方向，使其作用在转动件40上，且第三导向件72可以根据力的转向需要，从而适应性的设置多个。
在图2和图3关于第三导向件72的示意结构中，两个第三导向件72沿第一方向间隔设置，这样设置不仅能够为连接绳索提供导向作用，以在第二安装件60移动的过程中，通过连接绳索将作用力传递给转动件40，还能够保证位于弹性件20相对侧的连接绳索始终保持拉紧状态，同时保证作用在转动件40上的两个力方向相反。
作为优选的方案，如图4所示，第三导向件72可以包括同轴的第一子滑轮721和第二子滑轮722，第一子滑轮721的直径小于第二子滑轮722的直径，连接绳索包括第一绳段51和第二绳段52，第一绳段51的一端与第一联动件A联动连接，第一绳段51的另一端与第一子滑轮721连接，第二绳段52的一端与第二子滑轮722连接，第二绳段52的另一端与第二安装件60连接。
通过上述设置，不仅能够保证位于弹性件20相对侧的连接绳索始终保持拉紧状态、保证作用在转动件40上的两个力方向相反，还能够通过变径轮的比例，使得弹性件较小的形变量获得第二安装件60较大的行程。
作为优选的方案，支撑架还可以包括与第一安装件10连接的第二导向件73，作为第一连接件30的绳索的另一端依次绕过第二导向件73和第一导向件71后与转动件40连接，其中，绳索与第二导向件73的切点位于弹性件20的轴线的延长线上。
通过在第一安装件10上设置第二导向件73和第一导向件71，一方面可限制弹性件20的位置，使得弹性件20不会因转动件40的转动而发生偏移，确保弹性件20尽量在第一方向移动；另一方面，可以设定绳索与转动件40成一角度，从而控制弹性件20使转动件40转动的弹力转矩。
第一导向件71与第二导向件73间隔设置在第一安装件10上，通过上述设置，在保证弹性件20不会随转动件40的转动发生偏移的同时还能够使第一连接件30时刻保持拉紧状态。
当然，在附图未示出的替代实施例中，第一导向件71与第二导向件73的具体布置方式还可以根据弹性件20、转动件40的相对位置进行选择。
上述实施例一的支撑架用于显示器装置时，第二安装件60为与显示器连接的滑块，滑块相对于第一安装件10可移动地设置。
通过上述设置，显示器装置能够停滞在第一安装件10上的不同高度位置，满足多场景使用需求，克服高度调节过程中调节步骤繁杂以及调节定位后难以保持稳定状态等问题。
如图6和图7所示，实施例一的支撑架用于升降桌时，升降桌包括桌面100、与桌面100连接的支撑架。这样，第一安装件10为桌面100，第二安装件60与升降桌的支腿101连接或者支腿本身就是第二安装件60，第一安装件10相对于支腿101在竖直方向可移动地设置。
通过上述设置，当需要升降桌的桌面100即第一安装件10上升或下降到所需位置时，向上提拉或者向下按压桌面100，此时连接绳索沿第一方向移动并带动转动件40发生摆动，第一连接件30在转动件40的摆动作用下同样沿第一方向移动，使弹性件20发生相应的变形，从而保证作用于转动件40上的两个力始终保持平衡，最终实现升降桌的桌面100在竖直方向上的任意位置悬停。
需要说明的是，在图6和图7中绳索90的作用是保证嵌设在支腿101内的两个第二安装件60能够在竖直方向上同步移动。当然，第二安装件60本身就是升降桌的支腿101内的固定腿。
在图6关于第一导向件71和第二导向件73的示意结构中，第一导向件71与第二导向件73沿与第一方向垂直的第二方向上间隔设置，且两个第一导向件71沿第一方向间隔布置。
实施例二
实施例二的支撑架与实施例一的支撑架的区别在于：第一联动件A和第二联动件C沿预设轨迹运动的具体方式，参考图8中轨道的示意结构。
具体地，该实施例中，并未设置与第一安装件10枢转连接的转动件40，而是在第一安装件10上设置了两个轨道。参考图8中轨道的示意结构，支撑架还包括均设置在第一安装件10上的第一轨道41和第二轨道42，第二轨道42的半径小于第一轨道41的半径，第一联动件A与第一轨道41滑动配合，第二联动件C与第二轨道42滑动配合。
需要说明的是，第一联动件A与第一轨道41滑动配合，第二联动件C与第二轨道42滑动配合时，第一联动件A和第二联动件C通过连接杆等方式固定连接，以保证第一联动件A和第二联动件C的联动关系。
实施例二中的其它结构及应用产品与实施一相同，此处不再赘述。
实施例三
实施例三的支撑架与实施例二的支撑架的区别在于：实施例三中只设置了第一轨道41，而未设置第二轨道42，以及第一导向件71的具体结构，参考图9中轨道和第一导向件71的示意结构。
这样，第一联动件A和第二联动件C均与第一轨道41滑道配合，第一联动件A和第二联动件C的预设轨迹重合。
此处需要注意的是，第一联动件A和第二联动件C是两个独立的联动件，第一联动件A和第二联动件C在垂直于第一安装件10的方向上重合；或者，第一联动件A和第二联动件C构成为一个整体的联动件，该联动件上设有两个联动点，其中一个联动点与第一导向件71连接，另一个联动点与第二连接件50连接。
作为优选的方案，参考图9中第一导向件71的示意结构，第一导向件71包括同轴设置的第一导向轮711和第二导向轮712，第一导向轮711的半径小于第二导向轮712的半径，绳索为两个，弹性件20与第一导向轮711通过一个绳索连接，第二联动件C与第二导向轮712通过另一个绳索连接。
此处需要说明的是，该实施例中，第一联动件A和第二联动件C沿垂直于第一轨道41的方向重合布置，其中，第一联动件A和第二联动件C为独立的两个联动件，或者第一联动件A和第二联动件C结合为一个新的整体联动件B，该整体联动件B具有与第一连接件30和第二连接件50分别联动连接的两个部位即可。
实施例三中的其它结构及应用产品与实施二相同，此处不再赘述。
实施例四
实施例四的支撑架与实施例一至三任一项的支撑架的区别在于：第二连接件50的具体结构，参考图1，图8至图12中第二连接件50的示意结构。
第二连接件50为连接杆，连接杆的一端与第一联动件A铰接，连接杆的另一端与第二安装件60铰接。
通过上述设置，待调节部件作用在第二连接件50上的重力的分力可通过第一联动件A作用于转动件40，使转动件40绕转动件40与第一安装件10的枢转点转动，当转动件40转动时，由于第一连接件30的一端与弹性件20连接，第一连接件30的第二端通过第二联动件C连接至转动件40，使第一连接件30在发生移动进而带动弹性件20发生形变，弹性件20因发生形变产生的弹力通过第一连接件30同样作用于转动件40上，此时待调节部件的重力的分力和弹性件20因发生形变产生的弹力共同作用于转动件40，根据力矩的平衡原理，最终实现第二安装件60能够在不同高度位置悬停。
第二连接件50对转动件40的重力转矩和第一连接件30对转动件40的弹力转矩满足如下条件：
M F-M G＝0，即G*L1*sin(b)/cos(c)＝F*L2*sin(a)，其中，M F＝F*L2*sin(a)；M G＝G*L1*sin(b)/cos(c)。
其中，G指的是待调节部件的重量，单位为N；F指的是弹性件20的弹力，单位为N；L1指的是转动件40的长度，单位为m；L2指的是转动件40上的第二联动件C到转动件40与第一安装件10的枢转点O之间的距离，单位为m；b指的是转动件40与第二连接件50之间的夹角；c指的是第二连接件50与竖直方向之间的夹角；a指的是转动件40与第一连接件30之间的角度。
需要说明的是，第二连接件50对转动件40的重力转矩和第一连接件30对转动件40的弹力转矩满足M F-M G＝0。当待调节部件通过第二安装件60在滑轨12上移动时，转动件40与第二连接件50之间的夹角b、第二连接件50与竖直方向之间的夹角c以及转动件40与第一连接件30之间的角度a会随之发生改变，这样能够确保G*L1*sin(b)/cos(c)＝F*L2*sin(a)公式的成立，即重力转矩与弹力转矩始终保持平衡(具体原理参见图5)，因此，通过上述设置，待调节部件可以在第一安装件10的任意高度位置上悬停。
实施例四中的其它结构可与实施例一至三任一项相同，此处不再赘述。
其他结构
如图1所示，支撑架还包括底座11和面板61。底座11的一侧通过螺钉等锁紧部件与第一安装件10相连接，底座11的另一侧与支撑面抵接，底座11用于安装第一安装件10，面板61安装于第二安装件60上并用于安装显示器等待调节部件。
第一安装件10安装于底座11上，面板61安装于第二安装件60上，并且第二安装件60可在竖直方向上沿着滑轨12移动，通过上述设置，显示器等待调节部件可随第二安装件60的移动而上下移动，满足更多应用场景的使用。
优选地，为确保第二安装件60的顺畅滑动，在第一安装件10上设有滑轨12，第二安装件60与滑轨12滑动配合。由于滑轨12具有滑动行程，第二安装件60在滑轨12上的滑动存在最高位置限位和最低位置限位。
如图11所示，第二安装件60位于滑轨12的最高位置，对于同一待调节件来说，此时弹性件20的形变量最小，即弹性件20的弹力最小；如图12所示，第二安装件60位于滑轨12的最低位置，对于同一待调节件来说，此时弹性件20的形变量最大，即弹性件20的弹力最大。
如图10至图12所示，支撑架还包括用于调整弹性件20的拉伸量的调节结构80。调节结构80包括螺杆82和与螺杆82螺纹连接的调节件81，调节件81与弹性件20连接，螺杆82可转动地固定在第一安装件10上，以使调节件81带动弹性件20沿螺杆82的轴线方向直线运动。
在上述技术方案中，调节结构80包括螺杆82和与螺杆82螺纹连接的调节件81，调节件81与弹性件20连接，螺杆82可转动地固定在第一安装件10上，通过上述设置，转动螺杆82能够驱动调节件81沿螺杆82移动，从而调节弹性件20的弹力，这样，支撑架能够适应不同承重的待调节部件。
该实施例中的调节结构80也适用于实施例一至四中的支撑架，此处不再进行赘述。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：通过将弹性件设置在第一安装件上，第一联动件A沿第一预设弧形轨迹可移动地设置，第二联动件C沿第二预设弧形轨迹可移动地设置，第一连接件的第一端与弹性件连接，第一连接件的第二端与第二联动件C联动连接，第二安装件与第一安装件之间具有相对移动，这样，当第二安装件和第一安装件之间发生相对移动时，第一联动件A沿第一预设轨迹移动，第二联动件C沿第二预设弧形轨迹移动，第一连接件发生移动以带动弹性件发生变形，第二安装件或第一安装件能够悬停在不同高度位置，满足多场景使用需求，另外，在进行高度调节时，只需向上拉动或向下按压待调节部件至所需位置即可实现在任意高度位置自由悬停，调节方便，克服了高度调节过程中调节步骤繁杂的问题。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
