Description
本发明涉及稳定器技术领域,具体涉及一种用于以省力的方式把持安装有拍摄装置的稳定器的机架组件。进一步,本发明还涉及带有该机架组件的稳定器。
已知的是,现有的手持稳定器一般由一个可固定拍摄装置的云台和一端与云台连接的、用于支承云台的机架组成,其中,该机架一般呈直立的单一杆状结构,可供拍摄者握持,在拍摄时用以托举拍摄部。由于该手持稳定器的操作按键和手持稳定器工作所需的电池均设置在机架内,这往往使得该机架很长。对于这种具有细长杆状结构的机架存在以下问题:当手持稳定器搭载相机时,由于相机负载较重,稳定器和相机的总重量的至少60%会集中在相机位置,即相机和稳定器的整体重心会高于用户握持手持稳定器的部位一段距离。这段距离使得用户为了平衡相机重量将需要花费很大力气,从而给用户的手腕或者手臂带来令人不适的压迫感,尤其是长时间使用这种托举的方式进行拍摄将会十分费力,这对摄影师的臂力要求很高,不符合现今提高人机工程学友好度和用户体验感的大趋势。
进一步,在手持稳定器的发展历程中,其整体形态基本上没有发生变化,即构造成单一的直杆状,这使得手持稳定器的使用形态非常单一,这无法满足用户在各种应用环境下希望以用户友好、操作方便地方式把持稳定器的实际需求。
因此,行业内仍存在提供一种使用形态丰富、符合人机工程学、稳定性好的稳定器及其机架组件的需求。

结合附图1-3,其中示出了带有本发明的机架组件100的第一实施例的稳定器101。其中该稳定器101包括用于固定诸如单反相机或者摄像机或者VR设备等的拍摄装置的云台103。如图1所示,其中示出的云台103为三轴云台,包括三个转轴结构,即俯仰轴结构、横滚轴结构和航向轴结构。其 中,所述俯仰轴结构可用于安装该拍摄装置,作为一种示例,可以通过俯仰轴结构内的电机带动拍摄装置做绕俯仰轴的俯仰运动;俯仰轴结构安装于横滚轴结构上,通过横滚轴结构内的电机带动拍摄装置做绕横滚轴的横滚运动;横滚轴结构安装于航向轴结构上,通过航向轴结构内的电机控制拍摄装置相机绕航向轴A1的转动。需说明的是,图示中虽然示出的是三轴云台,但本发明实施方式中提供的方案同样适用于二轴云台。
进一步,如图1所示,该稳定器101还包括用于支承该云台103的机架组件100。其中该机架组件包括:沿该云台103的航向轴A1的方向延伸的第一机架部1,该第一机架部1作为示例地大体呈圆筒状,其具有连接至云台103的第一端11和远离该云台103的第二端12。其中第一机架部1以其第一端11支承该云台103,更具体地,第一机架部1的第一端11连接至云台103的航向轴结构从而实现对整个云台103的支承。进一步优选地,该第一机架部1在其第二端12带有用以连接外部配件的螺孔,其中该外部配件例如但不限于为三脚架、闪光灯等其他配件。其中该螺孔可以为1/4的通用螺孔。由此,可以简单的方式允许用户根据需要将诸如为三脚架、闪光灯等外部配件与机架组件相连接,从而扩展云台的使用范围。
如图1所示,根据本发明的机架组件100的第一机架部1与现有技术相比,其竖向高度明显降低,作为示例,该第一机架部1的高度可大体为现有稳定器的机架高度的约三分之一至二分之一。优选地,该第一机架部1将其一部分外周面用作为布置稳定器101的功能按键的布局区,优选该功能按键至少包括拍摄装置的控制按键。例如,可以将稳定器用于与外部设备电气连接的接口(作为示例,USB接口或者充电接口或者SD卡接口等)和稳定器的操作按键(作为示例,诸如拍摄装置控制按键)集中布置在第一机架部1的最左侧的外周面上(在图1中被遮挡,未被示出)。这样的布置,一方面便于用户在操作稳定器时,能够在把持稳定器时利用空闲的手指操作拍摄装置的控制按键从而控制拍摄装置拍摄,从而提高了用户使用时的用户体验。另一方面,当稳定器与外部设备进行有线式电气连接时,诸如充电操作或者与外部设备数据连接时,外接的引线并不会妨碍用户对稳定器的正常操作,这同样提高了用户使用时的用户体验。
更进一步,在第一机架部1的一侧还设置有自该外周面外突的操作旋钮,如图1所示出的那样。优选地,该操作旋钮邻近于操作按键布置,从而允许用户同样可以在把持稳定器时利用闲置的手指操作该操作旋钮。本领域技术 人员能够理解,以这种方式,可以有效地提高用户使用时的用户体验。
可以理解的是,该第一机架部1是由具有一定强度的工程塑料或者金属。为了便于用户把持,可以例如对第一机架部1的外周面进行磨砂处理,从而防止第一机架部1从用户手中的意外滑脱。
如图1所示,该机架组件100还包括沿垂直于该云台103的航向轴A1的方向延伸的第二机架部2。其中该第二机架部2具有连接至该第一机架部1的第一端21和远离该第一机架部1的第二端22,其中第二机架部2在其第一端21处支承第一机架部1。如图1所示,作为一种优选示例,该第一机架部2和第一机架部1可以被构造为一体件,这例如在第一机架部1和第二机架部2由塑料制成时,通过模制的方式制出。本领域技术人员能够理解,在第一机架部1和第二机架部2采用一体件的方式形成时,可以减少制造稳定器或者机架组件时的零部件数量并相应地降低组装成本。当然,本领域技术人员能够理解,该第一机架部1和第二机架部2也可以为彼此连接的独立部件,在此情况下,可以允许第二机架部2以绕自身轴向相对于第一机架1部枢转的方式连接至第一机架部1。
作为一种示例,该第二机架部2截面大体呈两端被倒圆的长方形的带轴线A2的筒状结构,优选地,该第二机架部2是关于其自身轴线A2成轴对称的筒状结构。其中该第二机架部2的宽度大致与第一机架部1的直径相同以允许其大致平滑过渡的方式连接至第一机架部1,这避免该机架组件100的外表面存在突变部或者台阶部,从而使机架组件100具有良好的把持手感或产品质感。优选地,该第二机架部2在其筒状结构的上端面和下端面均设置有用于在用户把持时增大与用户的手面间的摩擦力的软胶。作为一种替代,也可以经由在第二机架部2的外周面上形成增大摩擦的纹理。
作为一种非限定性的示例,该第二机架部2被构造成稳定器101的、用于容置电池的电池仓。其中该电池仓可以设计为允许用户自外部打开以对电池进行替换操作,也可以设计为禁止用户打开并仅以充电接口对所容置的电池进行充电操作的结构。当然,本领域技术人员可以理解,该第二机架部也可以构造成用于布置功能按键等其他用途。可以理解的是,该第二机架部1可以是由与第一机架部2相同的材料制成,例如但不限于为塑料或者金属。
如图1所示,该机架组件100还包括相对于该第二机架部2成角度地设置的把持杆3,其中该把持杆3具有连接至该第二机架部2的连接端31和远离该第二机架部2的、在图1中示出为位于连接端31上方的把持端32,这 使得该机架组件被构造为允许经由该把持杆3以大致竖向对准稳定器及拍摄装置的整体重心的方式支承该稳定器(将在下文中结合图6进行更详细的描述)。具体来说,如图1所示,该把持杆3可以被构造为自连接端31向上延伸的、大体呈圆形截面的筒状结构。在该把持杆3的把持端32处优选地设置有与用户的手面形状贴合的弧面以增大把持杆3和用户手面之间的接触面。进一步优选地,在该把持端32处沿其外周面设置有至少一个稳定器101的操作件,该操作件例如可以是按键、拨轮或者指压开关等。经由这样的布置,允许用户在把持端32处把持稳定器时,仍能用空闲的手指操作稳定器101的操作件,从而提高了用户使用时的用户体验。
优选地,该把持杆3可以在其连接端31或把持端32带有用以连接外部配件8(如图6所示)的螺孔,其中该外部配件例如但不限于为三脚架、闪光灯等其他配件。
在上文中大致描述了本申请的稳定器101及其机架组件100的构造。在本文中,为了克服现有技术中所存在的稳定器的机架组件使用形态单一的问题,在本申请中将机架组件100构造为由彼此间可具有不同相对位置关系的多个部件组成,且基于把持杆3绕第二机架部2的轴线A2枢转所导致的、把持杆3和第一机架部1的相对位置关系,使机架组件100至少具有多个使用形态(在下文中结合附图6-11加以详述)且该机架组件100能够在这多个使用形态之间变形。
在本文中,该把持杆3绕第二机架部2的轴线A2枢转可以是经由设置在第二机架部2与把持杆3之间的枢转机构来实现的。当然,也可以想到的是,以上枢转也可以是经由使第二机架部2绕其自身轴线A2相对于第一机架部1枢转来实现的。在下文中,将结合多个不同的实施例对此加以详述。
在图1所示出的实施例中,其中第一机架部1和第二机架部2被构造为一体件。在此情况下,把持杆3可以经由设置在把持杆3和第二机架部2之间的枢转机构4以允许把持杆3绕第二机架部2的轴线A2可枢转的方式将把持杆3的连接端31连接至第二机架部2的第二端22,从而允许用户调节该把持杆3与第一机架部1的相对位置关系。有别于现有技术中单一使用形态,这使得图1中的机架组件100能够具有多个使用形态并且机架组件100能够在多个使用形态之间变形,这允许用户可以根据实际的应用环境对机架组件的使用形态进行灵活调整,以确保以符合人机工程学的方式操作该稳定器(有关机架组件的形态变化将在下文中结合附图6-11加以详细描述)。
具体而言,该把持杆3可以绕第二机架部2的轴线A2枢转,从而允许改变把持杆3相对于第一机架部1的相对位置关系,因此根据本申请的稳定器的机架组件100具有多个不同的使用形态,例如在图1中的示出的机架组件100处于第一使用形态下,在该第一使用形态下,其中把持杆3与第一机架部1大体上是共面的且所述把持杆3自第二机架部2起以靠近云台103布置的方式延伸。在本申请中,把持杆3与第一机架部2大体是共面的是指作为两者的轴线的两条直线大体能够形成一个平面。同时,该把持杆3以靠近云台103布置的方式延伸,在图1中,该把持杆3以朝向图示的上方的方式延伸。经由将把持杆3靠近云台103布置,以允许在稳定器搭载有拍摄装置时,经由把持杆以基本竖向对准该稳定器及拍摄装置的整体重心的方式把持该稳定器100(参见图6以及下文关于图6的描述),这允许用户能够以省力的方式操作该稳定器100。
进一步,当用户将把持杆3可以绕轴线A2如图1所示地沿顺时针方向枢转90度,此时可以使机架组件100处于第二使用形态下,在该第二使用形态下,把持杆3将处于大体上正交于第一机架部1的位置(也大体上垂直于由轴线A1和轴线A2所限定的平面),此时允许用户经由把持杆3支承该机架组件100,例如但不限于可以将把持杆搭靠在其支撑物或者用户的肩上,从而减轻了用户的负担(参见图10以及下文关于附图6的描述),这允许用户能够以用户友好的方式操作该稳定器100。
更进一步,当用户将把持杆3绕轴线A2如图1所示地继续沿顺时针方向枢转90度时,此时可以使机架组件100处于第三使用形态下,在该第三使用形态下,把持杆3与第一机架部1大体上是共面的且所述把持杆3自第二机架部2起以远离云台103布置的方式延伸。具体来说,在图1中,该把持杆3以朝向图示的下方的方式延伸。经由将把持杆3朝向下方的延伸,从而使得机架组件整体大致呈“∩”的形状,即第二机架部2位于中间,而把持杆3和第一机架部1分别以平行且部分重合的方式位于第二机架部2的两端。这允许用户可以经由把持杆3和第一机架部1以共同夹持(例如但不限于,用户的肩部)的方式来把持该机架组件100,这并不仅能够非常省力的支承该稳定器,还可以防止稳定器在工作过程中的意外倾斜或者滑脱。由此可见,在本申请中,期望将把持杆3绕轴线A2的枢转角度范围设置为在0-180度之间。当然,本领域技术人员能够理解,把持杆3绕轴线A2的枢转角度范围并不限于以上角度,可以根据实际需要对该枢转角度范围进行灵活设 定。
进一步优选地,如图1所示,可以独立于上述绕轴线A2的枢转,该把持杆3也可以绕正交于该第二机架部的轴线A2的枢转轴线(参见附图2-3,其中的枢转轴线A3)可枢转的方式连接至第二机架部2的第二端22,从而使把持杆3相对于第二机架部2所成的角度是可调的。归因于该角度可调性,允许用户可以根据所搭载的拍摄装置的重量和实际的应用环境调节用户把持稳定器机架的角度和方式,以确保以符合人机工程学的方式操作该稳定器。
本领域技术人员能够知晓,上文中提及的把持杆3绕第二机架部2的轴线A2的枢转可以经由枢转机构来实现,而把持杆3绕枢转轴线A3的枢转也可以类似地经由独立于该枢转机构的另外的枢转机构来实现。同样可行的是将上述两个枢转机构集成为单个双轴枢转机构以减少稳定器机架组件的零部件数量。在下文中,将结合附图2-3给出了设置在第二机架部2和把持杆3之间的双轴枢转机构的两种示例性实施例。然而,需要指出的是,上述示例并不意图限定本申请的保护范围,本领域技术人员在不脱离附图2-3所给出的发明构思的基础上能够做出很多的常规变型,但仍落入本申请的保护范围。
在图2中示出了将双轴枢转机构的第一种示例方式。其中该图2所示出的枢转机构包括:固定连接至该第二机架部2的连接板55;其中,该连接板55上开设有多个供紧固件穿设的通孔,从而经由设置在孔中的紧固件将连接板固定连接至第二机架部2。固定连接至该连接板55上的转轴51,其中该转轴51例如以一体成型的方式支承在连接板55上,当然该转轴51也可以通过例如粘结或者焊接的方式支承在连接板55上并随之一同旋转。同样可以理解的是,该连接板55是可以省略的,即可以将转轴51直接固定连接至第二机架部2。进一步如图2所示,该枢转机构还包括有枢转座41,其中该枢转座41的一端可旋转地支承在该转轴51上以便绕第二机架部轴线A2相对于第二机架部2进行枢转。进一步,还包括固定连接至把持杆3的枢转体61,在本实施例中,该枢转体也被构造为转轴61。其中该转轴61绕枢转轴线A3可枢转地支承在枢转座41的另一端,其中该第二机架部轴线A2正交于所述枢转轴线A3。
具体来说,该枢转座41包括:位于其一端的用于容置转轴51的沉孔,在该沉孔中设置有用于旋转支承该转轴51的轴承部(未图示出);以及设置在 枢转座41另一端处的一对连接臂42,其中在一对连接臂42之间限定出内部空间421,由此将转轴61夹设在该内部空间421中。该把持杆3可经由连接环套设在该转轴61上,以使得把持杆3相对于该枢转座41绕枢转轴线A3是可枢转的。由此可见,经由上述设计,使得枢转座43经由转轴51绕第二机架部轴线A2的枢转和把持杆3绕枢转轴线A3的枢转成为可能。
如图2所示,其中该把持杆3的一端设置有固定连接的连接环,其中经由该连接环使得把持杆以固定套设在转轴61上的方式容置在一对连接臂42之间的内部空间421中。经由一对连接臂42对连接环31的夹持作用可以进一步阻止连接环和转轴61在枢转轴线A3方向上的不期望的运动,从而使把持杆3仅可绕枢转轴线A3枢转。在本实施例中,上述枢转座43可以是例如经由注塑成型一体成型制成,之后将转轴51和转轴61分别插入到枢转座43中以实现枢转功能。由此,以简单可靠的方式实现了对机架组件使用形态的调整。
为了限定把持杆3绕枢转轴线A3的枢转角度范围,优选地,还包括用于限定该把持杆3的枢转角度范围的第二限位机构,其中如图2所示,该第二限位机构包括:设置在转轴61的端部处的轴肩,其中该轴肩在转轴61的部分外周上延伸以限定出限位槽611。作为一种优选的示例,在该轴肩上设置有多个螺纹孔,由此可以经由将诸如为螺钉的紧固件穿设该螺纹孔和设置在连接环上的相对应的螺纹孔来把持杆3固定连接至转轴61。作为一种示例,其中该限位槽611是以轴肩不沿枢转体的全部外周延伸所形成的,其中限位槽611所对应的圆心角的角度范围对应于把持杆3的枢转角度范围,即该限位槽611的两侧壁形成为转轴61绕枢转轴线A3枢转时的止挡端壁。进一步,该第二限位机构还包括固定不动地设置在连接臂42上的作为止挡件的支撑销43,其中该支撑销43延伸入由轴肩51所限定出的限位槽52中,从而经由支撑销43与限位槽611的两端的止挡端壁的配合阻止把持杆3超出其枢转角度范围的转动。作为一种非限定性的角度范围,在本实施例中,该把持杆3在约120度的角度范围内枢转。更进一步,该把持杆3在约90度的角度范围内枢转。
在更有利的方面中,为了使把持杆3可以保持在用户调整好的角度位置处,在图2示出的示例中还包括用于将该把持杆3锁止在预定角度位置的第二锁止机构,其包括:设置在该转轴61的端部处的凹口612,其中该凹口612可经由对转轴61的一端加工出开口而形成,当然也可以在注塑成型该转 轴61时一体形成该凹口612;以及相对于该凹口612沿枢转轴线A3方向在压紧位置和松开位置之间活动动作的锁止块62,如图2所示,其中该锁止块62大体呈截头圆锥形且其外轮廓被定尺寸为当其处于锁止位置时与凹口612形成摩擦接合和/或形状配合,由此经由该摩擦接合和/或形状配合来锁止把持杆3绕枢转轴线A3的枢转;以及调节件63,其被构造成经由其自身的旋转使该锁止块62在压紧位置和松开位置之间动作。具体来说,调节件为与该枢转座41上的螺纹孔相配合的螺纹件,其中该螺纹件的一端固定连接有设置在枢转座外侧的扭力扳手,而其另一端连接至该锁止块62。在使用时,用户经由设置在枢转座41外侧的扭力扳手从而驱动该调节件63旋转,在调节件63旋转时,经由其与枢转座中的未示出的螺纹间的螺纹配合实现了调节件63在枢转轴线A3方向上的直线运动,从而使锁止块62在其压紧位置和松开位置之间动作。对于摩擦接合和/或形状配合来说,其可以经由选定锁止块62和凹口612的材料对的摩擦系数或者在锁止块62和凹口612上设置对应的形状配合结构来实现,这些对于本领域技术人员而言都是已知的,在此不再赘述。
更进一步,为了避免外部灰尘和潮气对转轴61的影响,当转轴61插入就位于枢转座41中时,还包括自外侧封闭的封盖,其中该封盖例如为带有卡脚的盖,其中该卡脚与设置在枢转座41的连接臂42中的卡槽相卡合,从而固定连接至枢转座41上。优选地,在该封盖设置有密封圈以提高对外部环境影响的密封性。
与此同时,为了限定枢转座41相对于作为第二机架部2的枢转角度范围,优选地,在图2示出的实施例还包括用于限定枢转座41相对于第二机架部的枢转角度范围的第一限位机构,其中该第一限位机构包括:设置在该枢转座41的前述沉孔内的、沿该转轴52的周向延伸的限位槽;以及固定套设在该转轴51的端部处的止挡件52,其中该止挡件52例如为与该转轴51形状配合并随转轴51同步转动的套环,其中该止挡件52带有延伸入该限位槽内的止挡突起521。由此,经由止挡突起521与该限位槽两端壁间的限位作用,从而限定出枢转座41相对于该第二机架部2的枢转角度范围。作为一种非限定性的角度范围,在本实施例中,该枢转座41在180度的角度范围内枢转。更进一步,该枢转座41在120度的角度范围内枢转。
在更有利的方面中,为了使枢转座41可以保持在用户调整好的相对于第二机架部2的角度位置处,还包括用于设定所述第二机架部2和枢转座 43(同样地,把持杆3)所成的角度的第一锁止机构,其中该第一锁止机构包括:绕转轴51设置的、能在夹紧位置和松开位置之间动作的夹紧块53,如图2所示,该夹紧块53例如成一端开口的燕尾状结构,其部分地包绕该转轴51设置,从而能在外力作用下在松开位置和夹紧位置之间动作。具体来说,当该夹紧块53处于松开位置时,夹紧块53在其自身张力的作用下外张从而并不与转轴51发生摩擦接合,这允许枢转座41及把持杆3相对于第二机架部2的自由转动;而当夹紧块53在外力作用下克服自身张力处于夹紧位置时,该夹紧块53经由其与转轴51间的摩擦接合和/或形状配合阻止该枢转座41绕第二机架部轴线A2的转动,由此可以设定所述第二机架部2和枢转座41及把持杆3所成的角度位置。进一步,用于施加外力的机构例如可以为螺纹件54,其中该螺纹件54可以与设置在该枢转座41上的螺纹孔相配合,其中该螺纹件54的一端固定连接有设置在枢转座41外侧的供用户操作的旋钮,同时该螺纹件54的另一端抵接至夹紧块。由此,经由用户操作旋钮,可以选择性地对夹紧块施加外力,从而使其在夹紧位置和松开位置之间动作,这最终实现了将枢转座41保持在用户调整好的相对于第一部件2的角度位置处。
进一步,在图3中示出了双轴枢转机构的另一种示例方式。类似于图2所示出的,其中该图3所示出的枢转机构包括:固定连接至该第二机架部的连接板55’。固定连接至该连接板55’上的转轴51’,其中该转轴51’支承在连接板55’上并随之一同旋转。同样可以理解的是,该连接板55’是可以省略的,即可以将转轴51直接固定连接至第二机架部2。进一步如图3所示,该枢转机构还包括有枢转座41’,其中该枢转座41’的一端可旋转地支承在该转轴51’上以便绕第二机架部轴线A2进行枢转。进一步,还包括固定连接至把持杆3的枢转体61’,在本实施例中,该枢转体被构造为球接头61’。其中该球接头61’绕枢转轴线A3可枢转地支承在枢转座41’的另一端,其中该第二机架部轴线A2正交于所述枢转轴线A3。在本实施例中,该球接头61’可以是完整的球体,也可以是局部地带有球面的球缺等,只要其能够与相应的夹紧座(在下文中将详述)形成球面接触即可。
类似于图2所示的,在图3中,该把持杆3在其一端也设置有固定连接的连接环,其中经由该连接环使得把持杆3固定套设在球接头61’并容置在一对连接臂42’之间的内部空间421’中。经由一对连接臂42’的夹持作用可以阻止连接环和球接头61’在枢转轴线A3方向上的不期望的运动,从而 允许把持杆3仅可绕枢转轴线A3枢转。
作为一种非限定性的示例,在组装时,首先将连接环插入到一对连接臂之间的内部空间421’中,随后沿枢转轴线A3方向自一侧将球接头61’置于位于内部空间421’中的连接环内。在该球接头61’的外周上设置有间隔出多条限位槽611’的螺纹孔,优选但不限于均匀间隔开呈120度的限位槽的三个螺纹孔。相应地,沿该连接环的外周与上述螺纹孔对应地设置有相同数量的螺纹孔(如图3所示),从而通过穿设入该连接环和球接头61’的紧固件将连接环固定连接至该球接头61’,从而允许把持杆3能够经由球接头61’绕枢转轴线A3枢转。
为了限定把持杆3绕枢转轴线A3的枢转角度范围,优选地,还包括用于限定该把持杆3的枢转角度范围的第二限位机构,其中如图3所示,该第二限位机构包括:经由该球接头61’的外周限定出的限位槽。具体来说,优选但不限于的是,限定出角度范围内呈120度的该限位槽。进一步,该第二限位机构还包括固定设置在枢转座41’的相对端处的作为止挡件的支撑销9’,将该支撑销9’相对于枢转座41’固定不动地设置在该限位槽611’内,从而可以经由该支撑销9’阻止把持杆3超出上述枢转角度范围的转动。需要指出的是,使把持杆3在约120度的角度范围内枢转只是示例性给出的角度范围,在本实施例中,也可以想到的是,该把持杆3在约90度的角度范围内枢转。
在更有利的方面中,为了使把持杆3可以保持在用户调整好的角度位置处,图3所示出的实施例还包括用于将该把持杆3锁止在预定角度位置的第二锁止机构,如图3所示,其包括:沿枢转轴线A3方向分别设置在该球接头61’的两侧的作为锁止件的一对夹紧座621和622,其中该一对夹紧座621和622被构造成沿图示出的枢转轴线A3方向在压紧位置和松开位置之间动作,并且在该锁止件处于压紧位置时以摩擦接合/形状配合的方式将把持杆3锁止在预定角度位置。具体来说,该一对夹紧座621和622带有适形于该球接头61’的外球面的球形凹面以在该一对夹紧座621和622被压紧时以摩擦接合/形状配合的方式止动该球接头’。进一步,第二部件锁止机构还包括被构造成经由其自身的旋转驱动所述锁止件在所述压紧位置和松开位置之间动作的调节件。
优选地,其中一对夹紧座621和622中的一个夹紧座622被构造成在压紧时是可胀开的。具体来说,可以通过使该夹紧座622具有不封闭的外周来 实现,即该夹紧座622是带有开口的。由于该夹紧座622是可胀开的,使得在球接头61’压紧该夹紧座622时,该夹紧座622能进一步胀开从而以更大的接触面积来容置该球接头61’,这从而能更好地锁止该球接头61’以防止把持杆3在外部意外作用时发生偏离预定角度位置的不期望的枢转。
如图3所示,其中该调节件包括与该枢转座41’上的螺纹孔相配合的螺纹件63。与图2一样,其中该螺纹件的一端固定连接有设置在枢转座外侧的扭力扳手,而其另一端连接至该锁止件。上述螺纹件63的使用方法与图2相同,在此不再赘述。
进一步优选地,在图3中示出的第二锁止机构还包括:经由紧固件连接到枢转座41’的引导套64以及在该引导套64内可滑动的楔紧块65,其中该楔紧块65的一端连接至螺纹件63,其另一端则以楔面配合的方式压靠至作为锁止件的夹紧座621,从而在经由螺纹件63在枢转轴线A3的轴向上在引导套64内被轴向引导地向内运动时,螺纹件63压紧该楔紧块65,进而该楔紧块65压紧夹紧座621。归因于楔紧块65和夹紧座621之间的楔面配合,能够将夹紧座621楔紧在其压紧位置而不易发生回弹。在夹紧座621被楔紧块65压紧时,经由夹紧座621和622的球形凹面将球接头61’以摩擦接合/形状配合的方式抱死,从而实现了将把持杆3锁止在预定角度位置。
更优选地,如图3所示,楔紧块65和夹紧座621之间带有相互配合的凹凸配合结构以使得该楔紧块65相对于夹紧座621是不可相对转动的。作为示例,如图3所示,其中夹紧座663上的凹凸配合结构为突出于形成楔面配合的夹紧座621的斜面的凸条,而楔紧块65上的凹凸配合机构则为设置在楔紧块65的斜面上的、与该凸条形状配合的凹槽。
需要指出的是,在图3示出的实施例中,作为优选,使以上球接头61’、一对夹紧座621和622和楔紧块65中的至少一个至少部分地由选自以下组的材料制成:尼龙、铝合金、钢和聚甲醛树脂(POM)。由此,经由这样的材料选择配对,使得球接头、一对夹紧座和楔紧块两两间的接触面上的摩擦系数得以增大,从而使锁止机构更加稳固可靠的工作。
更优选地,为了避免外部灰尘和潮气对球接头的影响,同样带有在图2中示出的自外侧封闭的封盖10’。
为了限定枢转座41’相对于第二机架部的枢转角度范围,优选地,在图3示出的实施例中还包括第一限位机构,其包括:设置在该枢转座的沉孔内的沿该转轴51’的周向延伸的限位槽;以及固定套设在该转轴51’的端部 处的止挡件71’,其中该止挡件71’带有延伸入该限位槽内的止挡突起721’。由此,经由止挡突起721’与该限位槽两端壁间的限位作用,从而限定出枢转座相对于该第二机架部的枢转角度范围。作为一种非限定性的角度范围,在本实施例中,该枢转座41’相对于该第二机架部2在180度的角度范围内枢转。更进一步,该枢转座41’相对于该第二机架部2在120度的角度范围内枢转。
在更有利的方面中,还包括将枢转座41’锁止在预定角度位置处的第一锁止机构,其中该第一锁止机构包括:绕所述第一转轴42’设置的、能在夹紧位置和松开位置之间动作的夹紧块81’,该夹紧块81’经由其与第一转轴51’间的摩擦接合和/或阻止绕所述转轴51’的转动,由此可以锁止枢转座41’在预定角度位置处。进一步,用于施加外力的机构例如可以为螺纹件54’,其中该螺纹件54’可以与该枢转座上的螺纹孔相配合,其中该螺纹件以与图2相同的方式被操作,在此不再赘述。由此,用户可以选择性地对夹紧块81’施加外力使其在夹紧位置和松开位置之间动作,这最终实现了将枢转座41’保持在用户调整好的角度位置处。
需要指出的是,尽管上文中第一锁止机构和第二锁止机构等的调节均是以用户手动调节的方式加以说明的,但本领域技术人员能够理解。手动仅仅只是一种示例的方式,采用自动的方式同样能够实现上述功能并因此应当视为落入本发明的保护范围。进一步需要注意的是,上述在不同实施例中公开的等特征彼此是独立的,可以单独或以任意组合来实现。
根据以上内容不难看出,在第一实施例中介绍的把持杆3除了可以相对于第二机架部的轴线A2和/或枢转轴线A3枢转从而调节该把持杆3相对于第一机架部1和/或第二机架部2所成的角度外,还允许用户可以根据实际的应用环境对机架组件的使用形态进行锁止保持,这些可以确保以符合人机工程学的方式操作该稳定器。
接下来,结合附图4-5来介绍带有本发明的机架组件的第二实施例的稳定器。
从图4-5所示,其中示出了带有本发明的机架组件100的第二实施例的稳定器101。与第一实施例相比,上述稳定器的区别仅在于机架组件100的结构,因此相同作用的部件仍然以相同的附图标记示出。
在图4-5中示出的该机架组件100包括:沿该云台103的航向轴A1的方向延伸的第一机架部1,该第一机架部1作为示例地大体呈圆筒状,其具 有连接至云台103的第一端11和远离该云台103的第二端12。其中第一机架部1以其第一端11支承该云台103,更具体地,第一机架部1的第一端11连接至云台103的航向轴结构从而实现对整个云台103的支承。与第一实施例相同,该第一机架部1在其第二端12也带有用以连接外部配件的螺孔并以其外周面用作为布置稳定器101的功能按键的布局区。有关第一机架部1的具体结构和材料,其与第一实施例的构造大体相同,在此不再赘述。
进一步,该机架组件100还包括沿垂直于该云台103的航向轴A1的方向延伸的第二机架部2。其中该第二机架部2具有连接至该第一机架部1的第一端21和远离该第一机架部1的第二端22,其中第二机架部2在其第一端21处支承第一机架部1。优选地,该第二机架部2以可绕其自身轴线A2相对于第一机架部1枢转的方式连接至该第一机架部1。作为一种示例,两者可以经由诸如轴承件的方式可彼此相对枢转地连接。
作为一种示例,该第二机架部2被构造成稳定器101的、用于容置电池的电池仓。可以理解的是有关第二机架部1的具体结构和材料,其与第一实施例的构造大体相同,在此不再赘述。
如图1所示,该机架组件100还包括相对于该第二机架部2成角度地设置的把持杆3,其中该把持杆3具有连接至该第二机架部2的连接端31和远离该第二机架部2的、在图4中示出为位于连接端31上方的把持端32。
作为一种优选的示例,可以在该第二机架部2的第二端22处开设有供该把持杆3穿设的通孔,其中该把持杆3以其在通孔中插入深度可调的方式容置在该通孔中。例如,这可以通过通孔的内径可变的方式(即通孔的松紧度可调)来实现。由此,可以实现把持杆3在与第二机架部2所成角度不可调整的情况下,以插入深度可调地方式固定至第二机架部2。在图4-5示出的实施例中,可选的是,使把持杆3与第二机架部2一起,借助于第一机架部1和第二机架部2之间的、绕第二机架部2自身轴线的枢转,调节把持杆3与第一机架部1的相对位置关系,从而允许用户可以根据实际的应用环境在机架组件多个使用形态之间进行灵活变形(图4-5中的使用形态与上述述及的使用形态相同,在此不再赘述),以确保以符合人机工程学的方式操作该稳定器(有关机架组件的使用形态变形将在下文中结合附图6-11详加描述)。
作为另一种优选的示例,如图4-5所示,其中机架组件100还可以包括被构造为允许把持杆3绕正交于第二机架部的轴线A2的枢转轴线A3枢转 的、设置在第二机架部2和把持杆3之间的分度锁紧机构7,其中该分度锁紧机构被构造成在其一端连接至第二机架部2的第二端22。如图5所示,该分度锁紧机构7还带有用于使分度锁紧机构7在接合位置和解除接合位置之间动作的调节件73,优选该调节件73为调节螺杆。其中该分度锁紧机构7处于解除接合位置时能以分度调节的方式相对于第二机架部转动,进而以分度调节的方式改变第二机架部2和把持杆3所成的角度。由此,可以实现对第二机架部和把持杆间所成角度的调节,从而能以符合人机工程学的方式操作该稳定器。
具体来说,如图4-5所示,该分度锁紧机构7包括一端带有钩弯部72的大体呈钩状的锁紧件7,其中该锁紧件7的钩弯部72被定尺寸为供该把持杆3以插入深度可调的方式穿设,在图5示出的方式,是经由设置钩弯部72的松紧度调节件74来实现把持杆3的插入深度可调的方式穿设,调节件74调节插入深度的方式在上文中已有描述,在此不再赘述。进一步,该锁紧件7的远离钩弯部72的一端被构造为带有与第二机架部2的第二端22处设置的第一端面齿盘23相啮合的第二端面齿盘71。其中调节件73穿设通过第一端面齿盘23和第二端面齿盘71并例如以螺旋进给运动的方式调节第一端面齿盘23和第二端面齿盘71之间的间距。当将调节件73向外旋出时,第一端面齿盘23和第二端面齿盘71之间的间距变大以使锁紧件7处于解除接合位置,这允许锁紧件7及其中的把持杆3相对于第二机架部2枢转从而以分度调节的方式改变第二机架部2和把持杆3所成的角度。当将调节件73向内旋入时,第一端面齿盘23和第二端面齿盘71之间的间距变小以使锁紧件7处于彼此接合位置,这允许锁止锁紧件7及其中的把持杆3相对于第二机架部2枢转从而保持已调整好的第二机架部2和把持杆3所成的角度。由此可见,经由该第一端面齿盘23和第二端面齿盘71的啮合可以实现以分度调节的方式改变所述第二机架部和所述把持杆所成的角度。进一步地,如图4所示出的,该第一端面齿盘23以相对于第二机架部2绕其轴线A2枢转地方式连接至第二机架部2,这例如可以通过使带有该第一端面齿盘23的第二机架部2的第二端22可相对于第二机架部2的轴线A2枢转地方式设置来实现。由此,在允许把持杆3相对于第二机架部2所成角度可调的情况下,还允许把持杆3与第一机架部1所成角度是可调的,这进一步允许用户能以符合人机工程学的方式操作该稳定器。
尽管在图4-5中示出了该分度锁紧机构以相互啮合的端面齿盘的方式形 成,但可以理解的是,该分度锁紧机构也可以采用形状配合的方式来实现。例如但不限于,该分度锁紧机构可以采用由手动销和以分度方式设置在第二机架部2上的多个销孔的方式来实现,其中手动销可经由偏压弹簧的作用被锁紧在一个销孔中从而实现分度调节。类似的结构已经在上文中清楚描述了,在此不再赘述。
需要指出的是,尽管上文中锁止机构、分度锁紧机构等的调节均是以用户手动调节的方式加以说明的,但本领域技术人员能够理解。手动仅仅只是一种示例的方式,采用自动的方式同样能够实现上述功能并因此应当视为落入本发明的保护范围。进一步需要注意的是,上述公开的这些特征彼此是独立的,可以单独或以任意组合来实现。
以下将结合附图6来说明根据本发明的稳定器处于第一使用形态下的操作。
正如前述,在现有技术中,安装有诸如为相机的拍摄装置的稳定器,由于相机的质量较大,而会发生稳定器和拍摄装置的整体重心偏离诸如为手臂或手腕的外部支承点一定距离导致费力的问题。特别地,随着拍摄的专业性要求越来越高,带有拍摄装置的稳定器的质量和尺寸都在增大,这更加加剧了稳定器及拍摄装置的整体重心偏离诸如为手臂或手腕的外部支承点一定距离导致费力的问题。
如图6所示出的,根据本发明的稳定器将现有的直杆状机架改型为多段式机架组件从而允许经由把持杆以大致竖向对准稳定器及拍摄装置的整体重心的把持稳定器,从而基本上消除或者完全消除了稳定器及拍摄装置的整体重心偏离外部支承点的问题。如图6所示,首先将例如为单反相机的拍摄装置102安装在本文所描述的稳定器上,在这里以低位拍摄的方式描述出稳定器的使用形态,但可以理解得到,该稳定器并不限于以低位拍摄的方式进行操作。
在低位拍摄时,为了保证更好的相机视角,会尽量靠前地安装相机,这使得稳定器及拍摄装置的整体重心(由稳定器及拍摄装置的整体重心线A4示出)进一步在图6中示出的向前移动。若采用现有技术中的直杆状机架,会使外部支承点和该整体重心线A4之间的距离更加拉大。采用本文中的稳定器,可以首先将稳定器平放成使第一机架部1大致平行地距地面一定高度的位置,此时第二机架部2大致竖向的取向且把持杆3大致横向地取向(此时,如图6所示,把持杆3与第一机架部1是大体上共面的且把持杆3自第 二机架部2起以靠近云台103布置的方式延伸)。此时根据稳定器的整体重心线A4的前移情况,可以相应地调节把持杆3相对于第二机架部2的插入深度,以确保把持杆3的把持端延伸超过该整体重心线A4。此时用户可以经由数次试握后使其在把持杆3上的手握部大致与该整体重心线A4共线的方式手提该稳定器(即以大致竖向对准稳定器及拍摄装置的整体重心的方式把持稳定器)。在确定好手在把持杆3上的手握部的合适位置后,用户可以将手臂伸直,使得手臂、手腕以及稳定器及拍摄装置的整体重心线A4三者对齐。在此情况下,由于稳定器及拍摄装置的整体重心和手臂、手腕之间基本不存在距离,使得用户能够以省力的方式把持该稳定器3进行拍摄,这大大提高了稳定器的人机工程学友好度,提升了用户的用户体验。
进一步,结合图7-9进一步描述了本文中稳定器在该第一使用形态下的另外的用法。
在图7-8中示出了稳定器100处于第一使用形态时的另一种用法,该用法优选适合于中位拍摄。在稳定器100已经处于第一使用形态下时,将连接至第一机架部1的第二端12的诸如为三角架的外部配件打开并将稳定器平放成使第一机架部1大致平行地距地面一定高度的位置。此时,用户同样地通过试握的方式根据稳定器及拍摄装置的整体重心线的大致位置确定出其在把持杆3上的最合适的握持位置。进一步,将处于打开状态下的三脚架8抵接至用户的身体,从而一方面利用身体消除稳定器在动作时的不期望的抖动;另一方面也可以经由身体与三角架8的摩擦力来部分地支承稳定器的重量。同时,用户还可以经由其另一只手自下方拖住机架组件的第一机架部1从而进一步支承稳定器的重量。并且在这种操作状态下时,用户的另一只手能够很方便的操作布置在第一机架部1上的功能按键。由此可见,这种用法同样具有很好的人机工程学友好度,这有利于用户体验的提升。
在图9中示出了稳定器100处于第一使用形态时的又一种用法,该用法优选适合于中高位拍摄。在稳定器100已经变形至第一使用形态下时,将连接至第一机架部1的第二端12的诸如为三角架的外部配件闭合并将稳定器大体呈竖向放置成距地面一定高度的位置。此时,由于稳定器及拍摄装置的整体重心大致处于竖向方向上,因此通过握持该外部配件即可以省力的方式把持该稳定器。同时,优选地,可以将把持杆枢转至与第一机架部大体平行的位置,从而允许用户的另一只手自其右侧进行辅助把持。并且在这种操作状态下时,用户的另一只手能够很方便的操作布置在把持杆3上的功能按键。 由此可见,这种使用形态同样具有很好的人机工程学友好度,这有利于用户体验的提升。
在图10中示出了该稳定器100的第二使用形态,该第二使用形态优选适合于高位拍摄。在该第二使用形态下,将连接至第一机架部1的第二端12的诸如为三角架的外部配件闭合并将稳定器大体呈竖向放置成距地面一定高度的位置。此时,如图10所示出的那样,可以将把持杆3枢转至大体正交于第一机架部1的位置,从而允许用户可以将把持杆3置于用户肩上并利用用户肩部对稳定器100进行支承。从而能够降低长时间把持稳定器的疲劳感和不适感。由此可见,在稳定器100的第二使用形态下时,可以允许用户以非常省力的方式支承稳定器,这有利于用户体验的提升。
在图11中示出了该稳定器100的第三使用形态,该第三使用形态优选适合于高位拍摄,在该第三使用形态下,可以将把持杆3枢转至如图11所示出的与第一机架部1大体上共面且使把持杆3自第二机架部2起以远离云台103布置的方式延伸(图11中,把持杆3朝向下方延伸),从而使得机架组件100整体大致呈“∩”的形状,即第二机架部2位于中间,而把持杆3和第一机架部1分别以平行且部分重合的方式位于第二机架部2的两端。这允许用户可以以夹持肩部的方式来支承该稳定器,这并不仅能够非常省力的支承该稳定器,还可以防止稳定器在工作过程中的意外倾斜或者滑脱。由此可见,这种使用形态同样具有很好的人机工程学友好度,这有利于用户体验的提升。
经过上文的描述可知,根据本发明实施例的机架组件具有多种使用形态,并且可以在上述使用形态之间灵活的切换和变形,因此根据本发明实施例的机架组件可以很容易满足用户在不同应用环境下的使用需求,这大大提升了用户的使用体验。
应当理解,虽然本说明书是按照各个实施例描述的,但并非每个实施例仅包含一个独立的技术方案,说明书的这种叙述方式仅仅是为清楚起见,本领域技术人员应当将说明书作为一个整体,各实施例中的技术方案也可以经组合,形成本领域技术人员可以理解的其它实施方式。
以上所述仅为本发明示意性的具体实施方式,并非用以限定本发明的范围。在不脱离本发明的构思和原则的前提下,本领域的技术人员可作的等同变化、修改与结合,均应属于本发明保护的范围。
