Description

支架 技术领域

背景技术
常规的电视支架和会议平板支架均为静止支架。近年来，市面上出现了可伸缩或可转动的单自由度(single-degree-of-freedom)支架，这种单自由度支架具有可升缩机构或可转动机构，其在电动机驱动下，可实现支架的单自由度地伸缩或转动。但是这种单自由度支架的运动范围受限，不能为用户提供很好的用户体验。另外，相关技术领域也存在两自由度(tWo-degree-of-freedom)的(既可以伸缩，又可以转动)支架，但是目前市面上的两自由度的支架的伸缩机构和转动机构只能依次地操作(例如先伸缩再转动，或先转动再伸缩)，无法同步地伸缩和旋转(即，在伸缩的同时转动，或在转动的同时伸缩)，因此控制效率低，用户体验差。

具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于阐明本公开，而非对本公开保护范围的限制。另外还需要说明的是，为了便于描述，附图中仅示出了与本公开相关的部分。
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申请。
需要说明的是，本公开中的方位措辞“上、下、前、后(背)、横、竖”皆为相对概念，并非绝对概念，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。为了叙述方便和简洁起见，本申请以支架通常的工作位置为参考基准，也即，将图8和图9中支架100朝向用户US的一侧称为前侧或正侧(front side)；将图8和图9中支架100背对用户US的一侧称为后侧或背侧；将支架100的滚轮81所在的一侧称为下侧；将支架100的工作面板3所在的一侧称为上侧。
一并参照图1-11，在一些示范性实施例中，支架100包括：基座8、工作面板3、至少一个第一运动机构M1，M2和第二运动机构。该工作面板3由所述基座8承载。该至少一个第一运动机构M1，M2连接 在工作面板3与基座8之间并被配置成能够沿第一方向(例如图3-5中的竖直方向)运动。该第二运动机构包括与工作面板3连接的第一端B和与基座8连接的第二端A，所述第二运动机构被配置成使得第一端B能够相对于第二端A进行相对运动，所述相对运动包括在不同于所述第一方向的第二方向(例如图3-5中的水平方向)上的运动。
第二运动机构可采用连杆的形式或伸缩件的形式，只要其能够通过相应的致动器致动以沿着第二方向运动即可。为了简洁起见，以下本文以连杆作为第二运动机构进行详细描述。
工作面板3包括前表面FS和背表面BS，前表面FS配置成适于布置待支承件OB。当待支承件OB为显示装置时，可选地，该工作面板3可包括该显示装置的后壳，以对该显示装置进行罩盖或支撑。所述至少一个第一运动机构M1，M2铰接在所述背表面BS上，并且每个第一运动机构M1，M2包括第一构件M11，M21和第二构件M12，M22，第一构件M11，M21配置成可相对于第二构件M12，M22伸缩，第二构件M12，M22固定连接到基座8；所述连杆5位于所述至少一个第一运动机构M1，M2下方，连杆5的第一端B在第一构件M11，M21与所述背表面BS的铰接位置C下方可活动地连接到工作面板3，所述连杆5的第二端A在所述至少一个第一运动机构M1，M2下方可活动地连接于基座8。待支承件OB可通过上方悬挂或底部支撑的方式布置在该工作面板3的前表面FS上。悬挂形式包括但不限于悬挂钉、悬挂条等传统壁挂结构。
如图1所示，以下以支架100包括三个第一运动机构(即支架100的两侧具有两个侧部运动机构M1，支架100的中部具有一个中间运动机构M2)为例进行说明(当然可以理解，支架100可以仅包括一个第一运动机构(例如中间运动机构)，或仅包括两个运动机构(例如两个侧部运动机构))。每个侧部运动机构M1的第一构件M11的第一端(图1中的上端)通过铰链机构11与工作面板3的背表面BS铰接，每个侧部运动机构M1的第一构件M11的第二端(图1中的下端)可活动地与该侧部运动机构M1的第二构件M12相接合。每个侧部运动机构M1的第二构件M12的第一端(图1中的上端)可活动地与该侧部运动机构M1的第一构件M11相接合。每个侧部运动机构M1的第二构件M12的第二端(图1中的下端)固定到基座8。位于中部的中 部运动机构M2的第一构件M21的第一端(图1中的上端)通过铰链机构21与工作面板3的背表面BS铰接，该中部运动机构M2的第一构件M21的第二端(图1中的下端)可活动地与该中部运动机构M2的第二构件M22相接合。中部运动机构M2的第二构件M22的第一端(图1中的上端)可活动地与该中部运动机构M2的第一构件M21相接合。该中部运动机构M2的第二构件M22的第二端(图1中的下端)固定到基座8。可选地，侧部运动机构M1和中部运动机构M2的铰链的旋转轴线为同轴设置，均在穿过铰接点C的轴线上(参见图3)，换句话说，所述三个第一运动机构M1，M2的第一构件M11，M21的第一端与所述工作面板3的背表面BS相铰接的铰接位置共线。
在一些实施例中，第一运动机构M1、M2可以是滑动机构。参见图7，侧部运动机构M1的第一构件M11和中部运动机构M2的第一构件M21可以分别配置为滑槽形式；相应地侧部运动机构M1的第二构件M12和中部运动机构M2的第二构件M22可以分别配置为滑轨，所述滑槽能够所在所述滑轨上滑动。当然滑槽和滑轨的位置可以互换，即，也可以将第一构件M11，M21配置为滑轨的形式，而相应地将第二构件M12，M22配置为与其相配合的滑槽形式。侧部运动机构M1和中部运动机构M2包括金属材料，当然也可以采用诸如硬质塑料等的其他材料，只要其能够满足支撑工作面板3和待支承件OB的强度和刚度要求即可。
另外，如图2所示，可以通过固定到基座8上的导向件(例如引导槽)12对第一构件M11、M21进行导向，以使得该第一构件M11、M21运动更加顺畅，不致于左右晃动过大，从而提高侧部运动机构M1和中部运动机构M2的运动稳定性。进一步地，可以通过第一固定件22和第二固定件23分别将中部运动机构M2的第二构件M22的两端固定到基座8。例如，如图7所示，可通过一对卡扣元件221，222将中部运动机构M2的第二构件M22的上端通过卡扣的方式固定到基座8上，从而提高中部运动机构M2的中部运动机构M22的支撑稳定性。
作为变型，所述第一构件M11，M21也可以为一端固定有滑块的支撑杆，第二构件M12，M22为与该滑块配合的滑轨，所述滑块能够在所述滑轨上滑动。同理，滑槽和滑轨的位置可以互换，即，也可以将第二构件M12，M22配置为一端固定有滑块的支撑杆，而相应地将第 一构件M11，M21配置为滑轨的形式。
请一并结合着参阅图7和图10A、10B、10C，图7中最左侧的框架结构除了工作面板3之外的其余部件，整体上都统称为基座，基座8是整个支架的基础。基座8包括位于所述工作面板3下部后方的装饰板6，装饰板6上提供有切槽61，以避开连杆5的行程，即供连杆5从其中穿过而不致于与装饰板6产生干涉。所述基座8还包括位于所述工作面板3后方的固定框架4，固定框架4包括第一固定板41和第二固定板42，第一固定板41上设有上述导向件12以对第一构件M11，M21进行导向，第二构件M12，M22的两端分别固定到所述第一固定板41和第二固定板42上。所述基座8的底部可包括多个滚轮81以便于移动支架100。至少一个滚轮上设有制动装置91，以便于对支架100进行制动。
连杆5可以呈弯曲形状，例如呈曲柄形状或呈V形。该弯曲形状沿着远离所述工作面板的方向凸伸，例如如图3所示，该弯曲形状沿着远离所述工作面板3的方向凸伸(即凸向背侧)。当然，连杆5还可以呈U形或C形等其他弯曲形状，这里不做限制，只要其运动时能从装饰板6的切槽61中穿过而不致于与装饰板6产生干涉即可。V形连杆的设计可以起到有效的避位作用，以致于设置避位槽时不至于切除装饰板过多。连杆5的第一端B可枢转地连接到所述工作面板3的下端，所述连杆5的第二端A铰接到所述基座8。
在操作支架100的过程中，第一构件M11，M21能够从第二构件M12，M22伸出或收缩。在第一构件M11，M21从第二构件M12，M22伸出的过程中，第一构件M11，M21带动工作面板3向上移动，工作面板3带动连杆5的第一端B围绕连杆5的第二端A朝向所述第二构件M12，M22枢转；在第一构件M11，M21缩回到第二构件M12，M22的过程中，第一构件M11，M21带动工作面板3向下移动，工作面板3带动连杆5的第一端B围绕连杆5的第二端A沿着远离所述第二构件M12，M22的方向枢转。
第一运动机构M1，M2的伸缩方向为竖直方向，所述工作表面3的运动为以下两种运动的复合运动：沿竖直方向的移动；和绕铰接位置C的转动。第一构件M11，M21相对于第二构件M12，M22的伸缩的距离小于第一构件M11，M21的纵向长度，优选小于第一构件M11， M21的纵向长度的90％，最优选小于第一构件M11，M21的纵向长度的80％。
连杆5的等效机械运动原理如图6所示，连杆5的等效结构为AB两点间的刚性直线连接杆，例如当支架100不具有前方装饰板6或与之相干涉的其他结构时，连杆5就可以直接制作成AB两点相连的直线段刚性件即可。
以下以图1中位于中间的中部运动机构M2为例对连杆5的等效机械运动原理进行简要阐述，中部运动机构M2的第一构件M21铰接位置C的运动轨迹为竖直方向上的上下移动，其随中部运动机构M2的第一构件M21伸缩而上下移动，行程与电动推杆行程相同，记为S。图3所示的极限位置为中部运动机构M2在伸缩至最长时的状态，即Smax时，此时工作面板3在竖直状态，其正前方挂的待支承件OB也为竖直状态。图4所示为运动轨迹处于中间某一状态，即C点竖直向下移动，同时B点绕A点(固定点)为圆心向前转动，带动工作面板3(即等效BC段)向下移动并倾斜。图5所示为中部运动机构M2缩至最短时的状态，即S＝0时，此时工作面板3在最低状态，前方挂的屏幕也为最大倾斜状态。
第一构件M11，M21从第二构件M12，M22伸出或收缩的致动方式可包括以下三种方式中的任何一种：纯手动致动或手动操作、纯电动致动方式、以及手动和电动相结合的方式。以下对这三种方式进行详细阐述。
在停电等应急情况下可以采用纯手动致动或手动操作，对于支架100采用纯手动致动或手动操作的方式而言，如图7所示，所述工作面板3上可设置有手柄HD，所述手柄HD例如可以包括推拉手柄。支架100的使用者US可以通过拉动该手柄HD以带动侧部、中部运动机构M1，M2的第一构件M11，M21使其可相对于第二构件M12，M22伸缩，第一构件M11，M21继而带动工作面板3上下移动，工作面板3进而带动连杆5的第一端B围绕连杆5的第二端A进行枢转。
通常情况下，支架100采用纯电动的操作方式，在这种情况下，支架100还包括至少一个第一运动机构致动器(图未示)，配置成致动第一运动机构M1，M2中的至少一个第一构件M11，M21使其可相对于第二构件M12，M22伸缩。每个第一运动机构致动器例如为以下 项目中的一个：电机驱动传动设备(例如直线电机驱动的顶杆机构)；液压传动设备(例如液压顶杆机构)；气动传动设备(例如气动顶杆机构)；凸轮传动机构(例如凸轮传动的顶杆机构)；齿轮-齿条传动机构(例如齿轮-齿条传动的顶杆机构)。举例而言，当采用电机驱动设备形式的第一运动机构致动器时：一方面可采用直线电机，其直接带动第一构件M11，M21使其可相对于第二构件M12，M22伸缩；另一方面，还可以采用传统的旋转电机，并通过多级齿轮变换机构和/或齿轮-齿条机构的转换来间接地带动第一构件M11，M21使其可相对于第二构件M12，M22伸缩。另外，选择性地或附加性地，支架100还包括至少一个连杆致动器(图未示)，配置成可驱动连杆5，以使连杆5围绕位于该连杆5的第二端A处的枢轴进行枢转。每个连杆致动器例如为旋转电机驱动设备或凸轮传动机构。鉴于以上所列的第一运动机构致动器和连杆致动器的致动方式均为相关领域的典型技术，这里不再赘述。另外，当第二驱动机构采用伸缩件的形式的收，其致动或驱动方式和第一驱动机构的致动或驱动方式大致相同，这里不再赘述。
作为第三种致动方式，第一构件M11，M21从第二构件M12，M22伸出或收缩还可以采用手动和电动相结合的方式。
图1和图2以支架100包括三个第一运动机构M1，M2为例进行了阐述。应当理解，支架100也可以配置成仅包括一个第一运动机构，例如仅包括一个中部运动机构M2；或者配置成仅包括也两个运动机构，例如仅包括两个侧部运动机构M1。
当所述至少一个第一运动机构仅包括一个第一运动机构时，该第一运动机构可邻近所述背表面BS和所述基座8的中部布置，并且所述至少一个第一运动机构致动器相应地仅包括一个第一运动机构致动器，以致动所述中部运动机构的第一构件使其相对于第二构件进行伸缩。采用单一致动器的方式来实现支架100双维度同步伸缩和旋转运动，即通过控制单一的伸缩致动器，实现支架在下降的同时，边下降边旋转，其成本低。
当所述至少一个第一运动机构仅包括三个第一运动机构时，中部运动机构邻近所述背表面BS和所述基座8的中部布置，两个侧部运动机构相对地设置在所述中部运动机构的两侧，例如背表面BS和所述基座8的边缘处。并且两个侧部运动机构的每一个的第一构件配置成能 够沿其第二构件进行滑动。进一步地，所述至少一个第一运动机构致动器可以设置成仅包括一个第一运动机构致动器，以致动所述三个第一运动机构的中部运动机构的第一构件相对于第二构件伸缩(即中部运动机构为主动运动机构或驱动运动机构)，并且所述两个侧部运动机构的每一个的第一构件配置成能够沿其第二构件的纵向滑动(即两个侧部运动机构为从动运动机构或被驱动的运动机构)，简言之，一个中间主动机构，加上两个侧部从动机构，再加上一个位于中部的致动器，该种致动模式的有益效果是：支架100作动起来更加顺畅，支撑更加稳定和鲁棒，不会导致工作表面3倾斜。可选地，所述至少一个第一运动机构致动器还可以设置成仅包括两个第一运动机构致动器，以分别致动所述两个侧部运动机构的第一构件使其相对于第二构件伸缩(即两个侧部运动机构为主动运动机构或驱动运动机构)，并且所述中部运动机构的第一构件配置成能够沿第二构件的纵向滑动(即第一运动机构为从动运动机构或被驱动的运动机构)，简言之，一个中间主动机构，加上两个侧部从动机构，再加上一个位于中部致动器，该种致动模式的有益效果是：支架100作动起来更加顺畅，支撑更加稳定和鲁棒，不会导致工作表面3倾斜。三个运动机构的行程相同，记为S，运动轨迹相同。两侧从动机构的作用为保证其工作面板3的稳定性，不会因主动力在中间而造成两侧摆动。
当所述至少一个第一运动机构仅包括两个第一运动机构时，该两个第一运动机构相对地设置在所述背表面BS和所述基座8的边缘处，并且所述至少一个第一运动机构致动器包括两个第一运动机构致动器，以分别致动所述两个第一运动机构的第一构件相对于第二构件伸缩。
支架100还可包括罩在所述至少一个第一运动机构致动器和至少部分所述至少一个运动机构M1，M2上的后盖7。后盖7从后方至少部分地包裹住支架100的机械结构部分(尤其是致动器和侧部、中部运动机构M1，M2)，锁付在固定框架4上以对支架100进行防尘，使支架100整体美观、整洁。
根据本公开的支架100的应用场景如图3-5，图10A-10C所示。待支承件OB在开会状态下需垂直状态悬挂，在需要书写、绘画等动作时，产生一定倾角并下拉，可以达到更好的书写体验效果。
根据本申请的一些示范性实施例提供的支架100包括以下有益效 果：由于支架100包括铰接在所述背表面BS上的至少一个第一运动机构M1，M2和位于所述至少一个第一运动机构M1，M2下方的第二运动机构(例如连杆5)，其中该至少一个第一运动机构M1，M2中的每个运动机构包括第一构件M11，M21和第二构件M12，M22，第一构件M11，M21配置成可相对于第二构件M12，M22伸缩，第二构件M12，M22固定连接到基座8；该连杆5的第一端B可活动地连接到工作面板3的下部，该连杆5的第二端A可活动地连接于基座8，致使支架能够同步地伸缩和旋转，因此控制效率高，用户体验好。支架在伸缩的同时同步翻转，实现满足待支承件(例如会议白板)在会议状态的竖直放置、和带一定角度的手写场景之间的快速切换和无极调节。
需要说明是，在本申请示范性实施例中，以会议用白板或显示器作为待支承件进行举例，但是应当理解，本公开的支架还可应用于其他类型的待支承件。
应当理解，尽管本文已经描述和示出了本公开的一些示范性实施例，但是本领域普通技术人员将容易地想到用于执行本文描述的功能和/或获得本文描述的结果和/或一个或多个优点的各种其他装置和/或结构，并且这些变化和/或修改中的每一个被认为在本公开的实施例的范围内。更一般地，本领域技术人员将容易理解，本文所述的所有参数、尺寸、材料和配置都是意为示例性的，并且实际参数、尺寸、材料和/或配置将取决于使用本公开教导的一个或多个特定应用。本领域技术人员将认识到或能够使用不超过常规实验来查明本文描述的具体实用新型实施例的许多等同物。因此，应当理解，前述实施例仅通过示例的方式呈现，并且在所附权利要求及其等同物的范围内，实用新型实施例可以以不同于具体描述和要求保护的方式实施。本实用新型实施例针对本文所述的每个个别的特征、系统、物品、材料、套件和/或方法。此外，如果这种特征、系统、物品、材料、套件和/或方法不是相互不一致的，则两个或多个这种特征、系统、物品、材料、套件和/或方法的任何组合都包括在本实用新型范围内。
除非另有限定，用在本公开中的所有技术和科学术语具有与本公开所属的领域中熟练的技术人员所通常理解的意义相同的意义。
如本文在说明书和权利要求中使用的短语“和/或”应当理解为意指如此结合的元件中的“任一个或两个”，即在一些情况下结合存在 并且在其他情况下不结合存在的元件。用“和/或”列出的若干元件应该以相同的方式解释，即，如此结合的元件中的“一个或多个”。除了由“和/或”子句具体标识的元件之外，可以可选地存在其他元件，无论与具体标识的那些元件相关还是不相关。因此，作为非限制性示例，当结合诸如“包括”之类的开放式语言使用时，对“A和/或B”的提及可以在一个实施例中仅指A(可选地包括除B之外的元件)；在另一个实施例中，仅指B(可选地包括除A之外的元件)；在又一实施例中，指A和B两者(可选地包括其它元件)等等。
本领域技术人员将理解本文中(诸如在“基本上所有光”中或在“基本上由......组成”中)的术语“基本上”。术语“基本上”还可包括具有“整个地”、“完全地”、“所有”等的实施例。因此，在实施例中，形容词基本上也是可移除的。在适用的情况下，术语“基本上”还可涉及90％或更高、诸如95％或更高、特别地99％或更高、甚至更特别地99.5％或更高、包括100％。术语“包括”还包括其中术语“包括”意味着“由......组成”的实施例。术语“和/或”特别地涉及“和/或”之前和之后所提及项目中的一个或多个。比如，短语“项目1和/或项目2”和类似短语可涉及项目1和项目2中的一个或多个。术语“包括”可在一个实施例中是指“由......组成”，但可在另一个实施例中也指“包含至少所限定种类并且可选地包含一个或多个其他种类”。
此外，本说明书中和权利要求中的术语第一、第二、第三等用于在类似元件之间进行区分，并不表示任何顺序、数量或者重要性。应理解，如此使用的术语在适当情形下是可互换的，并且本文所描述的本公开的实施例能够按与本文所描述或示出不同的顺序进行操作。
应注意，以上提及的实施例说明而不是限制本公开，并且本领域技术人员将能够在不背离所附权利要求的范围的情况下设计许多替代实施例。在权利要求中，放置在括号之间的任何参考标记不应被解释为限制权利要求。动词“包括”及其词形变化的使用并不排除存在与权利要求中所陈述的那些不同的元件或步骤。本公开权利要求书中的措辞“一”或“一个”不排除复数，其仅仅旨在叙述的方便，不应当理解为对本公开保护范围的限缩。
本公开可借助于包括若干不同元件的硬件、以及借助于适当编程的计算机来实现。在枚举若干器件的装置权利要求中，这些装置中的 若干个可由同一个硬件项体现。在相互不同的从属权利要求中叙述某些措施的纯粹事实并不指示不能有利地使用这些措施的组合。
本公开进一步适用于包括本说明书中所描述和/或附图中所示出的表征特征中的一个或多个的装置。本公开进一步涉及包括本说明书中所描述和/或附图中所示出的表征特征中的一个或多个的方法或过程。
本公开中所论述的各种方面可组合起来，以便提供另外的优点。另外，本领域技术人员将理解实施例可组合起来，并且多于两个实施例也可组合起来。此外，一些特征可形成一个或多个分案申请的基础。
