具体实施方式
在详细描述实施例之前，应该理解的是，本发明不限于本申请中下文或附图中所描述的详细结构或元件排布。本发明可为其它方式实现的实施例。而且，应当理解，本文所使用的措辞及术语仅仅用作描述用途，不应作限定性解释。本文所使用的“包括”、“包含”、“具有” 等类似措辞意为包含其后所列出之事项、其等同物及其它附加事项。特别是，当描述“一个某元件”时，本发明并不限定该元件的数量为一个，也可以包括多个。
本实用新型提供一种支架，该支架可以安装在其他物体，例如汽车上，作为手机或其他电子产品的车载支架。应当指出的是，该支架可以应用在很多场合，例如一些办公室家具上；也不限于作为手机支架，其可以用于可释放地支撑其他待固定物，例如装饰品或展示品等。在下面的实施例中，是以手机支架为例对本实用新型的支架作详细说明。
如图1至图4所示，根据本实用新型第一实施例的支架10包括第一夹持件12、第二夹持件14以及连接件16。第一夹持件12和第二夹持件14用于协作地夹持固定一待固定物，例如一手机18(见图5和图6)。第一夹持件12和第二夹持件14的至少其中之一可活动地连接至所述连接件16，使得在所述手机18的推挤下所述第一夹持件12和第二夹持件14的至少其中之一能够活动以在第一夹持件12和第二夹持件14之间形成一用以夹持所述手机18的夹持空间19。
在所示的实施例中，第一夹持件12和第二夹持件14两者都是可活动地连接至连接件16。更具体而言，第一夹持件12和第二夹持件14两者都是可转动地连接至连接件16。第一夹持件12包括可转动地安装至连接件16的第一安装部20和与第一安装部20固定连接的第一夹持臂22。第一安装部20设有第一安装孔24，连接件16凸伸一第一连接销26，第一安装部20利用第一安装孔24可转动地套设在第一连接销26上，实现第一夹持件12相对于连接件16可转动。并在第一安装孔24和第一连接销26之间设置阻尼结构，例如橡胶垫，使得在实现第一夹持件12可相对连接件16转动的同时实现阻尼连接。
类似地，第二夹持件14包括可转动地安装至连接件16的第二安装部28和与第二安装部28固定连接的第二夹持臂30。第二安装部28设有第二安装孔32，连接件16凸伸一第二连接销34，第二安装部28利用第二安装孔32可转动地套设在第二连接销34上，实现第二夹持件14相对于连接件16可转动。应当理解的是，可活动地连接也可以是其他形式的活动连接，比如平行移动地连接。在第二安装孔32和第二连接销34之间设置阻尼结构，例如橡胶垫，使得在实现第二夹持件14可相对连接件16转动的同时实现阻尼连接。
因此，在手机18或其他待固定物的推挤下第一夹持件12和第二夹持件14都能够相对连接件16转动以形成夹持所述手机18的夹持空间19，手机18对第一夹持件12和第二夹持件14的推挤可以是因为手机自身的重力引起的，也可以是施加于手机18上的外力引起的，例如用户按下手机，或者以其他形式产生所述推挤行为。外力撤离后，第一安装孔24和第一连接 销26以及第二安装孔32和第二连接销34之间摩擦力提供第一夹持件12和第二夹持件14夹持手机18的夹持力。
第一夹持件12具有第一夹持面36，第二夹持件14具有第二夹持面38。随着第一夹持件12和第二夹持件14的转动，第一夹持面36和第二夹持面38能够分别在各自的夹紧位置和释放位置之间转动。同时参考图3和图4，位于夹紧位置时，第一夹持面36和第二夹持面38相对张开以在其间形成所述夹持空间19。第一夹持面36和第二夹持面38的底端之间具有一距离，在所述释放位置时的该距离小于在夹紧位置时的该距离。也就是说，从释放位置转动至夹紧位置时，第一夹持面36和第二夹持面38的底端是相互张开的，而从夹紧位置转动至释放位置时，第一夹持面36和第二夹持面38的底端是相互收拢的。
为了防止手机从支架10滑落，第一夹持件12和第二夹持件14的至少其中之一在其底部设有一支撑面，用以在夹持固定手机18过程中，支撑住手机18。在所示的实施例中，第一夹持件12和第二夹持件14分别设有第一支撑面40和第二支撑面42。在夹紧位置，第一支撑面40与第二支撑面42共面。应当理解的是，本实施例是以手机为例进行说明，手机底侧一般为平面，因此第一支撑面40和第二支撑面42共面。但在支撑底侧不是平面的待固定物时，第一支撑面40和第二支撑面42可以不共面，而是呈一角度设置。
如图5和图6，为夹持固定手机18的过程示意图。首先，用户将手机18放入已经固定在车辆或者其他物体上的支架10中，使手机18的底侧两角部首先接触第一夹持件12和第二夹持件14的第一夹持面36和第二夹持面38。在重力的作用下或者在用户的按压下，手机18向下运动，推挤第一夹持面36和第二夹持面38，使第一夹持面36和第二夹持面38都从自己的释放位置朝向其夹持位置转动，直至转动到其夹持位置。在其夹持位置，手机18的宽度与第一夹持面36和第二夹持面38之间的距离相当，因此手机18在横向上被第一夹持面36和第二夹持面38夹持固定，同时在竖直方向上被第一支撑面36和第二支撑面38共同支撑，从而完成手机18的固定。上述操作，用户只需要将手机放入支架10中或者轻按手机，即可实现手机的固定，支架结构简单，固定操作方便。
但是第一实施例只能固定宽度与第一夹持面36和第二夹持面38之间的距离相当的手机18，下面将介绍能适用于不同宽度手机的其他实施方式。
图7-9为支架的第二实施例的示意图。本实施例中的支架200包括第一夹持件212、第二夹持件214以及连接件216。第一夹持件212、第二夹持件214与前述实施例中的第一夹持件12、第二夹持件14的结构、连接和功能可以完全一样，因此不再赘述。下面仅介绍连接件216的区别。
在所示实施例中，第一夹持件212在第一连接位218阻尼连接至连接件216，第二夹持件214在第二连接位220阻尼连接至连接件216。在本实施例中，连接件216为一可伸缩结构，使得第一连接位218和第二连接位220之间的距离是可变的。因此，本实施例的支架200可以适应宽度在第一连接位218和第二连接位220的最大距离和最小距离之间的多种不同宽度的手机18或其他待固定物。
连接件216包括一本体222以及第一连接部224和第二连接部226。第一连接位218设置在第一连接部218上，第二连接位220设置在第二连接部226上。第一连接部224和第二连接部226都可伸缩地连接至本体222，因此随着第一连接部224和第二连接部226相对于本体222的伸缩，第一连接位218和第二连接位220之间的距离随之变化，则第一夹持件212和第二夹持件214的夹持面之间的距离也会变化，也适应不同的手机宽度。
第一连接部224设有第一导轨228，本体222设有与第一导轨228滑动配合的第一导槽230，通过第一导轨228在第一导槽230内的滑动实现所述第一连接部224的伸缩。第一导轨228的末端设有径向延伸的凸缘232，主体222在第一导槽230的外侧设有挡缘234。第一连接部224可在一收缩位置和一伸展位置之间活动，在该收缩位置，第一连接部224与主体222抵靠在一起，第一导轨228完全收容在第一导槽230内；在该伸展位置，第一导轨228伸出第一导槽230，且第一导轨228的末端的凸缘232与主体222的挡缘234抵靠，定义第一导轨228的最大外伸量。第一导轨228和第一导槽230之间还设置有阻尼结构以实现第一连接部224可保持在其最大收缩位置和最大伸展位置之间的任意位置，在本实施例中，该阻尼结构为套设于凸缘232上的橡胶垫235，橡胶垫235抵顶在凸缘232和第一导槽230的底壁之间以提供凸缘232稳定于收缩位置和伸展位置之间任意位置的摩擦力。应当理解的是，设置有阻尼结构以实现第一连接部224可保持在其最大收缩位置和最大伸展位置之间的任意位置仅作为本实用新型的一种实施方式，在其他实施例中，也可以通过其他方式实现第一连接部224保持在其最大收缩位置和最大伸展位置之间的其他中间位置，例如卡合方式，本实用新型对此不作限定。
类似地，第二连接部226设有第二导轨236，本体222设有与第二导轨236滑动配合的第二导槽238，通过第二导轨236在第二导槽238内的滑动实现所述第二连接部226的伸缩。第二导轨236的末端设有径向延伸的凸缘240，主体222在第二导槽238的外侧设有挡缘242。第二连接部226与本体222的连接和作动关系与第一连接部224和本体222的连接和作动关系一致，因此不再赘述。
通过外力调节第一连接部224和第二连接部226的相对距离，以适应宽度在第一连接位218和第二连接位220的最大距离和最小距离之间的不同手机宽度，并由阻尼结构将第一连接 部224和第二连接部226稳定在这一相对距离，从而实现夹持多种不同宽度的手机18或其他待固定物。
图10和图11描绘了支架的第三实施例。本实施例相对于图7-9的实施例的区别在于，支架300的第一连接部324与本体322之间设置一第一偏压元件328，第一偏压元件328对第一连接部324施加朝向本体322的偏压力。本体322设有第一本体凹槽330，第一连接部324设有对应第一本体凹槽330的第一连接部凹槽332。第一偏压元件328的两端分别固定在所述第一本体凹槽330内和第一连接部凹槽332内。
类似的，第二连接部326与本体322之间设置一第二偏压元件334，第二偏压元件334对第二连接部326施加朝向本体322的偏压力。本体322设有第二本体凹槽336，第二连接部326设有对应第二本体凹槽336的第二连接部凹槽338。第二偏压元件334的两端分别固定在所述第二本体凹槽336内和第二连接部凹槽338内。
设置了第一和第二偏压元件328、334后，第一连接部324和第二连接部326可相对于本体322弹性伸缩，使得第一夹持件312和第二夹持件314可以自适应手机或其他待固定物的宽度，并提供夹紧力以夹紧手机或其他待固定物，因此使用更加方便。而且，由于这些本体凹槽和连接部凹槽的设置，在未固定手机时，这些连接部会处于完全收缩位置，偏压元件收容在这些凹槽内，不会外漏，从而不会影响支架的外观。
在本实施例中，这些偏压元件为拉伸弹性元件，例如拉伸弹簧。在其他实施例中，也可以采用其他具有拉伸特性的弹性元件。
图12至图14是支架的第四实施例。在本实施例中与前述实施例相比，区别在于支架400是采用齿轮结构进行伸缩的，因此可以适应多种不同宽度的手机18或其他待固定物。
第一连接部424设有第一导轨428，本体422设有与第一导轨428滑动配合的第一导槽430，通过第一导轨428在第一导槽430内的滑动实现所述第一连接部424的伸缩。第一导轨428的末端设有径向延伸的凸起432，主体422在第一导槽430的外侧设有挡缘434。第一导轨428上设有第一齿部435。
类似地，第二连接部426设有第二导轨436，本体422设有与第二导轨436滑动配合的第二导槽438，通过第二导轨436在第二导槽438内的滑动实现所述第二连接部426的伸缩。第二导轨436的末端设有径向延伸的凸起440，主体422在第二导槽438的外侧设有挡缘442。第二导轨436上设有第二齿部444。
本体422内设有一齿轮单元446，齿轮单元446转动连接于本体422，该齿轮单元446与第一导轨428的第一齿部435和第二导轨436的第二齿部444同时啮合。在所示的实施例中， 齿轮单元446具有两个相互啮合的齿轮，这两个齿轮与第一齿部435和第二齿部444分别啮合，且第一齿部435与第二齿部444的运动方向呈一角度，第一导轨428和第二导轨436能够同步地朝相互靠近或相互远离的方向滑动，带动第一连接部424和第二连接部426做伸缩运动。
第一连接部424和第二连接部426可各自在一收缩位置和一伸展位置之间活动，在该收缩位置，第一导轨428和第二导轨436分别完全收容在第一导槽430和第二导槽438内，第一连接部424和第二连接部426与主体422抵靠在一起，定义第一导轨428和第二导轨436的极限内缩位置；在该伸展位置，第一导轨228和第二导轨436同步地伸出第一导槽430和第二导槽438，且第一导轨428的凸起432和第二导轨436的凸起440分别与主体422的挡缘434和挡缘442抵靠，定义第一导轨428和第二导轨436的最大外伸量。
在本实施例中，使用了两个齿轮的齿轮单元446，以实现相互靠近或相互远离的同步滑动。在其他实施例中，齿轮单元446可以使用其他偶数数目的齿轮，第一齿部435和第二齿部444分别与最外侧两个齿轮啮合。
支架400设置偏压元件以提供支架400夹持手机18或者其他待固定物的夹持力，如图14所示，偏压元件为作用于齿轮的扭簧450，扭簧450构造成朝向收缩位置偏压齿轮，通过该扭簧对齿轮单元446的弹性偏压，第一连接部424和第二连接部426可相对于本体422弹性伸缩，并提供夹紧力以夹紧手机或其他待固定物，因此使用更加方便。而且，在未固定手机时，这些连接部会处于完全收缩位置。
图15和图16是支架的第五实施例。与第四实施例相比，区别在于支架500是采用另一种齿轮结构进行伸缩的，因此也可以适应多种不同宽度的手机或其他待固定物。
第一连接部524的第一导轨528具有第一齿部535，第二连接部526的第二导轨536上设有第二齿部544。本体522设有与第一导轨528滑动配合的第一导槽530，并设有与第二导轨536滑动配合的第二导槽538。本体522内设有齿轮单元546，该齿轮单元546与第一齿部535和第二齿部544同时啮合。在所示的实施例中，齿轮单元546具有一个齿轮，该齿轮与第一齿部535和第二齿部544同时啮合于齿轮的两侧，且第一齿部535与第二齿部544的运动方向平行，第一导轨528和第二导轨536能够同步地朝相互靠近或相互远离的方向滑动，带动第一连接部524和第二连接部526做伸缩运动。
在本实施例中，使用了具有一个齿轮的齿轮单元546，以实现相互靠近或相互远离的同步滑动。在其他实施例中，齿轮单元546可以使用其他奇数数目的齿轮，第一齿部535和第二齿部544分别与最外侧两个齿轮啮合。
在本实施例中，支架500设置的偏压元件为与扭簧450类似地作用于齿轮的扭簧，通过该扭簧对齿轮单元546朝向收缩位置的弹性偏压，第一连接部524和第二连接部526可相对于本体522弹性伸缩，并提供夹紧力以夹紧手机或其他待固定物，因此使用更加方便。而且，在未固定手机时，这些连接部会处于完全收缩位置。
在上述本实施例，都是以设置两个连接部(第一连接部和第二连接部)为例进行介绍的，应当理解的是，仅设置一个连接部也是可行的。例如，仅设置可伸缩的第一连接部，第一连接位设置在第一连接部上，而第二连接位设置在本体上。利用第一连接部的伸缩也可以实现第一夹持件和第二夹持件的夹持面之间的距离变化，以适应不同的手机宽度。
综上所述，本文提出一种支架，用于可释放地支撑一待固定物，其包括第一夹持件、第二夹持件以及连接于所述第一夹持件和第二夹持件之间的连接件，所述第一夹持件和第二夹持件的至少其中之一可活动地连接至所述连接件，所述第一夹持件和第二夹持件的至少其中之一构造成能够在所述待固定物的推挤下活动以在所述第一夹持件和第二夹持件之间形成一用以夹持所述待固定物的夹持空间。在一些具体实施例中，连接件是可伸缩的，可以适应不同待固定物的宽度。使用时，用户只需要将待固定物放入支架中或者轻按待固定物，即可实现带固定物的自动固定，支架结构简单，固定操作方便。
本文所描述的概念在不偏离其精神和特性的情况下可以实施成其它形式。所公开的具体实施例应被视为例示性而不是限制性的。因此，本发明的范围是由所附的权利要求，而不是根据之前的这些描述进行确定。在权利要求的字面意义及等同范围内的任何改变都应属于这些权利要求的范围。
