Description

用于固定移动终端的固定支架 技术领域
本实用新型涉及固定支架的技术领域，特别是涉及一种用于固定移动终端的固定支架。
背景技术
随着个人移动终端的普及，以及个人移动终端的通信、导航、多媒体等功能的日益完善，使得个人移动终端正逐渐成为人们生活中不可缺少的用品，尤其是手机，出于安全考虑，当用户在驾车过程中需要使用手机时，如何固定手机，就成为了必须要解决的问题。
目前，手机支架已普遍存在人们的生活当中，市面上常见的手机支架类型一般分为磁吸型、重力型和弹力夹持型，其中，磁吸型支架则包括吸附磁盘和隔磁片，吸附磁盘利用胶水粘合在汽车的驾驶台上，而隔磁片就需要粘贴在手机的背面，但吸附磁盘只能固定安设在一辆汽车内，不能随意的装卸，缺乏灵活性，另外，移动手机的电池容量有限，而智能手机工作耗电量大，出行者通常需要借助汽车电池对智能手机进行充电，及时补充电能，以免影响使用，但目前手机采用有线连线方式充电，存在使用不便的问题，而且现有的车载手机充电装置功能单一，未能满足使用要求；重力型支架主要为依靠重力作用的自动夹，原理是将夹持物的重力转化为支架夹臂的夹持力，但由于手机类电子设备多为轻巧型设备，会导致重力型支架的夹持力度偏小，在汽车面临急刹等特殊情况时，手机往往会掉落，影响行车安全；弹力夹持型支架是利用弹簧的弹力夹紧夹持物，安全可靠性高，但在使用时需要双手操作，取放手机较为麻烦。
现有的电动支架，取代了手动支架，但需要通电才能正常使用。现有的 电动支架使用电驱动装置进行正向驱动或反向驱动，带动夹臂收缩或张开，从而夹紧或释放移动终端。这种电动支架不论是收缩还是张开都需要电驱动装置，即需要给电动支架一个充足的电源，当移动终端夹持在电动支架上且电源出现了故障时，这时电动支架就无法使用，移动终端也无法取下，需要再接通电源才能取下移动终端，反而增加了一些使用麻烦，不能应对突发情况，实用性较差，而且现有的电动支架结构比较复杂，增加了制造成本。

请参照图1至图13，本实用新型实施例一提供的用于固定移动终端的固定支架，该固定支架包括：支撑座10，支撑座10包括前壳11和后壳12，前壳11和后壳12相对设置并在前壳11与后壳12之间形成容置腔101，前壳11上设有多个安装柱111，后壳12通过螺丝与前壳11的各安装柱111连接。例如，后壳12可以设有多个安装柱111，前壳11通过螺丝与后壳12的各安装柱111连接，但并不以此为限。支撑座10的前壳11具有承载移动终端(手机、平板电脑、显示面板等)的支撑面112，优选地，支撑面112可以为平面或弧面。
第一夹臂20和第二夹臂30，第一夹臂20和第二夹臂30分别设置在支撑座10的左右两侧,第一夹臂20可相对支撑座10沿左右方向移动。
在本实施例中，第一夹臂20和第二夹臂30均可相对支撑座10沿左右方向移动。支撑座10上设有第一导向块131和第二导向块132，第一夹臂20上沿左右方向设有第一导向槽22，第一导向块131设置在第一导向槽22内，第二夹臂30上沿左右方向设有第二导向槽32，第二导向块132设置在第二导向槽32内。本实施例中，第一导向块131和第二导向块132均设置在前壳11上，例如，第一导向块131和第二导向块132还可以设置在后壳12上。优选地，第一导向块131和第二导向块132均为圆柱形。例如，在其它实施例中，支撑座10上设有第一导向槽22和第二导向槽32，第一夹臂20上沿左右方向设有第一导向块131，第一导向块131设置在第一导向槽22内，第 二夹臂30上沿左右方向设有第二导向块132，第二导向块132设置在第二导向槽32内，但并不以此为限。
第一夹臂20远离支撑座10的一端设有第一夹持部23，第二夹臂30远离支撑座10的一端设有第二夹持部33，第一夹持部23和第二夹持部33用于夹持移动终端。第一夹持部23和第二夹持部33均为弯曲状，在第一夹持部23的内侧面设有多个第一防滑条231，第二夹持部33的内侧面设有多个第二防滑条331，优选地，第一防滑条231和第二防滑条331为软胶材质，第一防滑条231和第二防滑条331不仅可以增加与移动终端的摩擦力，防止移动终端从固定支架上滑落，还可以避免第一夹持部23和第二夹持部33刮蹭移动终端的外表面。
弹簧40，弹簧40的两端分别与第一夹臂20和第二夹臂30相连，且弹簧40始终处于拉伸状态。在本实施例中，第一夹臂20和第二夹臂30均可相对支撑座10左右移动。在其它实施例中，第一夹臂20可相对支撑座10左右移动，而第二夹臂30与支撑座10固定连接，此时弹簧40的一端与第一夹臂20连接，弹簧40的另一端可以与第二夹臂30相连，也可以与支撑座10相连。在本实施例中，弹簧40的数量为一个。在其它实施例中，弹簧40的数量还可以为两个，此时，其中一个弹簧40的一端与第一夹臂20相连，弹簧40的一端另一端与支撑座10相连，另一个弹簧40的一端与第二夹臂30，弹簧40的一端另一端与支撑座10相连，但并不以此为限。

驱动机构50，驱动机构50包括驱动电机51、传动组件52和传动轮53，驱动电机51与传动组件52相连，传动组件52与传动轮53相连，传动轮53安装在支撑座10上且可相对支撑座10转动，传动轮53具有宽部531和窄部532，宽部531相对传动轮53中心的距离大于窄部532相对传动轮53中心的距离，驱动电机51通过传动组件52驱动传动轮53相对支撑座10转动，传动轮53的宽部531或窄部532可选择性地与第一夹臂20和第二夹臂30抵靠接触，以推动第一夹臂20和第二夹臂30沿左右方向移动并改变第一夹臂20与第二夹臂30之间的夹持距离。当传动轮53的宽部531与第一夹臂20和第二夹臂30抵靠接触时，第一夹臂20和第二夹臂30相互远离，此时固定支架呈现打开状态，当传动轮53的窄部532与第一夹臂20和第二夹臂30抵靠接触时，第一夹臂20和第二夹臂30在弹簧40的作用下相互靠拢，此时固定支架呈现夹紧状态。
本实施例中，传动轮53的外周从窄部532平滑过渡至宽部531。优选地，传动轮53为椭圆形结构。在其它实施例中，传动轮53可以为凸轮结构，可以理解地是椭圆形结构的传动轮53可以由两个凸轮结构的传动轮53组成。当只有第一夹臂20可相对支撑座10沿左右方向移动时，传动轮53可采用凸轮结构。
在本实施例中，传动组件52包括蜗杆521和齿轮522。驱动电机51与蜗杆521相连，驱动电机51用于驱使蜗杆521正、反转动，蜗杆521与齿轮522啮合，齿轮522与传动轮53固定连接在一起，使齿轮522与传动轮53一起转动。驱动电机51用于驱使蜗杆521正、反转时，传动轮53的宽部531或窄部532选择性地与第一夹臂20和第二夹臂30抵靠接触，实现第一夹臂20与第二夹臂30相互靠拢夹持移动终端或远离松开移动终端。
图15是本实用新型中固定支架的结构框图。请参照图1至图13和图15，固定支架还包括控制开关61、电源接口62、控制器63和传感器64，控制开关61、电源接口62、传感器64、驱动电机51分别与控制器63电性连接。 控制器63设置在支撑座10内，控制器63为固定支架内的电路板。控制开关61设置在支撑座10上，并位于支撑座10的一侧，控制开关61用于控制驱动电机51驱使传动轮53相对支撑座10转动以实现松开移动终端。电源接口62连接在支撑座10上，并位于支撑座10的端部，电源接口62用于与外部电源连接，并给控制器63供电能。控制开关61连接在支撑座10上，控制开关61，被触发时输出一控制信号给控制器63，控制器63输出电流给驱动电极51，使驱动电极51转动，从而带动蜗杆521转动并使传动轮53也随之转动，进而驱使第一夹臂20与第二夹臂30相互远离松开移动终端，此时弹簧40处于第一拉伸状态。传感器64用于检测第一夹臂20与第二夹臂30之间是否放置有移动终端，当传感器64检测到第一夹臂20与第二夹臂30之间放置有移动终端时，输出一检测信号给控制器63，控制器63输出电流给驱动电极51，使驱动电极51转动，从而带动蜗杆521转动并使传动轮53也随之转动，进而驱使第一夹臂20与第二夹臂30相互靠拢夹紧移动终端，此时弹簧40处于第二拉伸状态，第一拉伸状态的弹力大于第二拉伸状态的弹力。优选地，传感器64设置于支撑座10的支撑面112，传感器64可以为红外传感器、距离传感器、光线传感器中的其中一种，但并不以此为限。
进一步地，当第一夹臂20与第二夹臂30的初始状态为张开时，控制器63控制驱动电机51驱使第一夹臂20与第二夹臂30相互靠拢；当第一夹臂20与第二夹臂30的初始状态为收拢时，控制器63控制驱动电机51驱使第一夹臂20与第二夹臂30相互远离，如传感器64没有检测到放置有移动终端，经过预设时间后，控制器63再控制驱动电机51驱使第一夹臂20与第二夹臂30相互靠拢。
本实用新型中用于固定移动终端的固定支架的第一夹臂20和第二夹臂30会自动松开或夹紧，当电源出现了故障时，因为第一夹臂20和第二夹臂30与传动轮53是抵靠接触，所以还可以手动的实现夹紧和松开的功能，结构简单，操作方便，自动化程度高，可以应对多种突发情况，实用性较高。
[实施例二]
图14是本实用新型实施例二中的固定支架在打开状态且去掉后壳的后视立体结构示意图。如图14所示，本实用新型实施例二提供的用于固定移动终端的固定支架与实施例一(图4)中的用于固定移动终端的固定支架的结构以及工作原理基本相同，不同之处在于，在本实施例中，传动组件52包括直齿轮521a和冠齿轮522a，直齿轮521a和冠齿轮522a代替了实施例一种的蜗轮蜗杆结构。驱动电机51a与直齿轮521a相接，直齿轮521a与冠齿轮522a啮合，冠齿轮522a与传动轮53固定连接在一起。当驱动器53驱使直齿轮521a正、反转时，实现第一夹臂20与第二夹臂30相互靠拢夹持移动终端或远离松开移动终端。其中直齿轮521a为柱状，直齿轮521a的齿分布在柱的外周，冠齿轮522a为圆形，冠齿轮522a的齿分布在圆的边缘并朝一侧凸出。在其它实施例中，直齿轮521a和冠齿轮522a可采用两个伞齿轮代替，即可实现交叉轴的传动模式。
本领域的技术人员应当理解的是，本实施例的其余结构以及工作原理均与实施例一相同，这里不再赘述。
在本文中，所涉及的上、下、左、右、前、后等方位词是以附图中的结构位于图中以及结构相互之间的位置来定义的，只是为了表达技术方案的清楚及方便。应当理解，所述方位词的使用不应限制本申请请求保护的范围。
以上所述，仅是本实用新型的较佳实施例而已，并非对本实用新型做任何形式上的限定，虽然本实用新型已以较佳实施例揭露如上，然而并非用以限定本实用新型，任何熟悉本专业的技术人员，在不脱离本实用新型技术方案范围内，当可利用上述揭示的技术内容作出些许更动或修饰，为等同变化的等效实施例，但凡是未脱离本实用新型技术方案内容，依据本实用新型的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本实用新型技术方案的保护范围之内。
