本申请实施例的第一方面提供一种摄像头装置，包括：承载件、驱动组件、升降机构、摄像头模组以及摄像头托架；其中，所述驱动组件安装在所述承载件上，所述升降机构转动设置于所述承载件上，所述驱动组件与所述升降机构传动连接；所述摄像头模组固定在所述摄像头托架上，所述摄像头托架设置在所述承载件上，且所述摄像头托架与所述承载件滑动连接；所述升降机构包括第一滚轮，所述第一滚轮与所述摄像头托架的侧壁抵接，所述第一滚轮用于在旋转过程中带动所述摄像头托架沿所述摄像头托架的轴向升降，以及在所述摄像头模组受到外力冲击时与所述摄像头托架相对滑动以缓冲所述外力冲击。
本申请实施例提供的摄像头装置，通过设置承载件可以对整个摄像头装置起到支撑作用，驱动组件可以驱动升降机构旋转，升降机构中的第一滚轮与摄像头托架抵接，第一滚轮旋转时与摄像头托架之间产生滚动摩擦，进而带动摄像头托架沿着摄像头托架的轴向升降；当摄像头模组受到外力冲击时，外力冲击通过摄像头模组传递至摄像头托架，从而会 使摄像头托架与第一滚轮之间产生滑动摩擦，即摄像头托架相对于第一滚轮向靠近承载件的方向滑动，以缓冲摄像头模组受到的外力冲击，从而对摄像头模组起到保护作用，以保护摄像头装置和电子设备。
另外，本申请实施例中的，升降机构和摄像头托架之间通过第一滚轮与摄像头托架之间的滚动摩擦实现摄像头装置的升降功能，通过第一滚轮与摄像头托架之间的滑动摩擦实现缓冲功能，这样可以不需要设置单独的缓冲机构，从而可以简化摄像头装置的结构，进而减小摄像头装置的体积和重量，以使摄像头装置更加方便设置，且降低摄像头装置的成本。
在一种可能的实现方式中，所述第一滚轮和所述摄像头托架中的至少一个上设置有摩擦面；所述摩擦面用于增大所述第一滚轮和所述摄像头托架的侧壁之间的摩擦力，以使所述第一滚轮在旋转过程中带动所述摄像头托架沿所述摄像头托架的轴向升降。
通过设置摩擦面，并且将摩擦面设置在第一滚轮或者摄像头托架中的至少一个上，这样可以增加第一滚轮和摄像头托架之间的摩擦力，从而保证第一滚轮可以带动摄像头托沿着摄像头托架的轴向升降。
在一种可能的实现方式中，所述摩擦面设置在所述摄像头托架上，且所述摩擦面位于所述摄像头托架与所述第一滚轮抵接的位置；所述摩擦面在所述摄像头托架轴向上的长度大于或等于所述摄像头托架沿所述摄像头托架的轴向升降的最大行程。
通过将摩擦面设置在摄像头托架上，可以降低摩擦面的设置难度，进而降低摄像头装置的加工成本；通过将摩擦面的长度设置的大于或等于摄像头托架的最大行程，从而保证摄像头托架可以带动摄像头模组到达完全伸出的状态，以保证摄像头装置的拍摄效果良好。
在一种可能的实现方式中，所述摩擦面为软胶面。
在一种可能的实现方式中，所述升降机构还包括第二滚轮；其中，所述第二滚轮与所述驱动组件传动连接，所述第二滚轮与所述第一滚轮传动连接；所述第二滚轮用于将所述驱动组件的驱动力传递至所述第一滚轮，以驱动所述第一滚轮旋转。
通过设置第二滚轮，然后将第一滚轮和第二滚轮传动连接，这样可以提高第一滚轮设置位置的灵活性，这样就可以降低第一滚轮的设置难度，进而简化第一滚轮的结构，降低摄像头装置的加工成本。
在一种可能的实现方式中，所述升降机构还包括N个第三滚轮；其中，所述第三滚轮设置在所述第二滚轮和所述第一滚轮之间，所述第三滚轮用于将所述第二滚轮和所述第一滚轮传动连接；N为大于或等于1的整数。
通过在第二滚轮和第一滚轮之间设置N个第三滚轮，这样可以使驱动组件的传动力经过多级传动后到达第一滚轮，由于多级传动可以改变第一滚轮的驱动力以及旋转速度，所以这样可以改变升降机构的驱动力，以及摄像头托架的升降速度。
在一种可能的实现方式中，所述承载件设置所述驱动组件的一面设有安装座；其中，所述安装座的底端固定在所述承载件上，所述安装座的顶端沿所述摄像头托架的轴向向远离所述承载件的方向延伸；所述升降机构转动设置在所述安装座上。
通过设置安装座可以为升降机构的设置提供位置，以使升降机构固定在承载件上；另外，通过将升降机构与安装座转动连接，以使升降机构可以相对于承载件旋转，进而带动摄像头托架沿着摄像头托架的轴向升降。
在一种可能的实现方式中，所述安装座的顶端设置有第一安装部，所述第一滚轮转动设置在所述第一安装部上；所述安装座的底端设置有第二安装部，所述第二滚轮转动设置在所述第二安装部上。
通过在安装座的顶端设置第一安装部，并将第一滚轮设置在第一安装部上，从而使第一滚轮的位置高于承载件的底部，以保证摄像头托架的行程较大，以保证摄像头模组可以处于完全伸出状态；通过将第二安装部设置在安装座的底端，并将第二滚轮设置在第二安装部上，这样可以使第二滚轮距离驱动组件更近一些，这样可以方便驱动组件和第二滚轮之间的传动连接，可以减少驱动组件和第二滚轮之间的传动部件，进而简化摄像头装置的结构。
在一种可能的实现方式中，所述第一安装部上设有用于容纳所述第一滚轮的开口；其中，所述第一滚轮的两端均设有连接杆，所述连接杆的直径小于所述第一滚轮的直径；所述第一滚轮位于所述开口内，所述第一滚轮的两端通过所述连接杆与所述第一安装部转动连接，以使所述第一滚轮与所述摄像头托架的侧壁抵接；所述第二滚轮和所述第一滚轮之间通过传动装置传动连接，且所述第一滚轮上的传动装置设置在连接杆上。
通过在第一安装部上设置开口结构，以保证第一滚轮可以和摄像头托架的侧壁抵接；通过在第一滚轮的两端均设有连接杆，且连接杆的直径小于第一滚轮的直径，这样可以为传动装置的设置提供安装位置，并且这样传动装置的设置不会影响第一滚轮和摄像头托架抵接。
在一种可能的实现方式中，还包括控制组件；其中，所述控制组件与所述驱动组件电连接；所述控制组件用于监测所述摄像头托架的位置，并根据所述摄像头托架的位置控制所述驱动组件旋转，以使所述摄像头托架位于伸出状态或缩回状态。
通过设置控制组件可以使摄像头组件位于伸出状态或者是缩回状态，因为在摄像头装置位于伸出状态时如果受到外力冲击，会使摄像头托架带动这摄像头模组向靠近承载件的方向滑动，这样摄像头装置就位于伸出状态和缩回状态之间，这样会影响摄像头装置的正常使用，通过设置控制组件，在摄像头装置就位于伸出状态和缩回状态之间时，控制组件就可以通过监测到摄像头托架的位置使驱动组件启动，并将摄像头装置调整至伸出状态或缩回状态，以方便下次使用。
在一种可能的实现方式中，所述控制组件包括两个距离监测组件；其中，两个所述距离监测组件间隔设置，且两个所述距离监测组件之间的距离为所述摄像头托架沿所述摄像头托架的轴向升降的最大行程。
通过设置两个距离监测组件，并将两个距离监测组件之间的距离设置为摄像头托架沿摄像头托架的轴向升降的最大行程，以提高监测到的摄像头托架位置的准确性。
在一种可能的实现方式中，每个所述距离监测组件均包括霍尔器件和磁性件；其中，所述霍尔器件与所述磁性件相对设置，且所述霍尔器件和所述磁性件中的其中一个设置在所述承载件上，所述霍尔器件和所述磁性件中的其中另一个设置在所述摄像头托架上，所述霍尔器件用于监测所述磁性件的位置；所述霍尔器件与所述驱动组件电连接。
通过将距离监测组件设置为包括霍尔器件和磁性件的结构，可以方便地将距离监测组件设置在摄像头装置上，并且霍尔器件和磁性件的结构简单，对摄像头装置的体积以及重量影响较小。
在一种可能的实现方式中，还包括导向组件，至一个所述导向组件沿着所述摄像头托架的周向间隔设置，以使所述摄像头托架沿着所述摄像头托架的轴向垂直升降。
通过设置导向组件从而使摄像头托架可以沿着摄像头托架的轴向垂直升降，以防止在摄像头托架升降过程中出现歪斜，进而防止摄像头托架过程中出现卡涩等问题，进而可以避免升降卡涩对摄像头托架带来的损伤。
在一种可能的实现方式中，每个所述导向组件均包括导向柱和升降滑板；其中，所述导向柱设置在所述承载件上，所述升降滑板设置在所述摄像头托架上；所述升降滑板围设在所述导向柱的外侧，且所述升降滑板与所述导向柱滑动连接。
通过设置导向柱和升降滑板，并且将升降滑板设置在摄像头托架上，将导向柱设置在承载件上，以使摄像头托架可以带动升降滑板沿着导向柱滑动，以使摄像头托架可以沿着摄像头托架的轴向垂直升降。
在一种可能的实现方式中，所述导向柱与所述升降滑板之间设置有多个滚珠。
通过在导向柱和升降滑板之间设置滚珠，可以减小导向柱和升降滑板之间的摩擦力，从而减小摄像头托架升降的阻力，从而可以节约驱动组件的能量。
在一种可能的实现方式中，还包括保护盖和透光件；其中，所述保护盖的中间区域设置有透光孔，所述透光孔处覆盖有所述透光件；所述透光件与所述摄像头模组远离所述承载件的一端接触连接；所述保护盖围设在所述摄像头托架、部分所述承载件以及所述升降机构的外侧。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
此外，本申请中，“前”、“后”等方位术语是相对于附图中的部件示意置放的方位来定义的，应当理解到，这些方向性术语是相对的概念，它们用于相对于的描述和澄清，其可以根据附图中部件所放置的方位的变化而相应地发生变化。
在本申请实施例中，“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
随着科技的快速发展，3C电子产品已广泛应该于人们的工作和生活中，尤其是手机、平板电脑、可穿戴设备等移动终端电子设备，3C电子产品即计算机(Computer)、通讯(Communication)和消费电子产品(Consumer Electronic)三类电子产品的简称。为了迎合人们的消费体验，电子设备上的摄像头的拍照功能从辅助已经逐渐的成为主打功能，但是随着摄像头在光学功能上变得更强大，摄像头的体积也会变得更大，从而导致电子设备的外观凸起严重，从而影响电子设备的外观精致性。
相关技术中，通过将摄像头设置为可升降式的结构，在拍摄时，将摄像头从电子设备中伸出，以使摄像头能够具有较大的光学可用空间；在无需拍摄时，将摄像头缩回电子设备内部，以使摄像头的体积较小，从而减小摄像头体积较大对电子设备外观的影响。其中，升降摄像头主要有手动按压弹出式、手动旋转式、变速电机自动式等。
然而，相关的升降摄像头的摄像头模组与传动导向机构通常采用刚性连接，当摄像头模组受到冲击时，产生的冲击力会全部作用于传动导向机构上，可能会使传动件或导向件产生断裂等不可逆损伤，造成摄像头模组出现升降卡涩或卡死的问题，从而导致升降摄像头的稳定性和可靠性差、寿命低等，增加缓冲组件则会使升降摄像头的体积增大，重量增大，进而导致升降摄像头对设置空间的要求更加苛刻，限制了升降摄像头的应用和发展。
基于上述问题，本申请实施例提供一种摄像头装置及电子设备，其中该摄像头装置为升降摄像头，可以极大的改善电子设备的外观效果和精致度；并且该摄像头具有缓冲功能，在摄像头的升降过程中可以全程缓冲作用在摄像头装置上的外力，可以对摄像头装置起到保护作用，进而可以延长摄像头装置和电子设备的使用寿命。
以下将结合图1-图15对本申请实施例提供的电子设备100进行说明。
本申请实施例提供一种电子设备100，该电子设备100可以包括但不限于为手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、手持计算机、对讲机、上网本、POS机、个人数字助理(personal digital assistant，PDA)、行 车记录仪、安防设备等具有摄像头装置的移动终端、固定终端或可折叠终端。

参见图3所示，手机还可以包括：主电路板140和电池150。其中，主电路板140和电池150可以设置在中框130上，例如，主电路板140与电池150设置在中框130朝向后盖120的一面上，或者主电路板140与电池150可以设置在中框130朝向显示屏110的一面上。其中，主电路板140在中框130上设置时，中框130上可以开设开口用于将主电路板140上的元件置于中框130的开口处。
其中，电池150可以通过电源管理模块与充电管理模块和主电路板140相连，电源管理模块接收电池150和/或充电管理模块的输入，并为处理器、内部存储器、外部存储器、显示屏110以及通信模块等供电。电源管理模块还可以用于监测电池150容量，电池150循环次数，电池150健康状态(漏电，阻抗)等参数。在其他一些实施例中，电源管理模块也可以设置于主电路板140的处理器中。在另一些实施例中，电源管理模块和充电管理模块也可以设置于同一个器件中。

中框130可以包括中板132和边框131。边框131可以围设在中板132的外周。边框131可以包括顶边框、底边框、左侧边框和右侧边框，顶边框、底边框、左侧边框和右侧边框围成环形的边框131。其中，中板132的材质可以为铝，也可以为铝合金，还可以为镁合金，对中板132的材质不作限定。边框131可以为金属边框，也可以为陶瓷边框，对边框的材质不作限定。其中，中板132和边框131之间可以卡接、焊接、粘合或一体成型，或者中板132与边框131之间通过注塑固定相连。
需要说明的是，在一些其他示例中，手机可以包括但不限于为图3所示的结构，例如手机可以包括：显示屏110、中板132和壳体，壳体可以为边框131和后盖120一体成型(Unibody)形成的壳体。这样摄像头装置200至少部分结构、主电路板140和电池150均可以位于显示屏110和壳体围成的容置空间中。
手机还可以包括：与摄像头装置200配合使用的闪光灯(图中未示出)，从而实现拍摄功能。摄像头装置200可以包括前置摄像头装置和后置摄像头装置。其中，后置摄像头装置以及闪光灯可以设置在中板132朝向后盖120的一面上，后盖120上开设可供后置摄像头装置的部分结构安装的安装孔121。前置摄像头装置可以设在中板132朝向显示屏110的一面上。本申请实施例中，前置摄像头装置和后置摄像头装置的设置位置包括但不限于上述描述。其中，在一些实施例中，手机内设置的前置摄像头装置和后置摄像头装置的数 量均可以为1个或N个，N为大于1的正整数。
可以理解的是，本申请实施例示意的结构并不构成对电子设备100的具体限定。在另一些实施例中，电子设备100可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
基于上述描述，本申请实施例中，以手机中设置后置摄像头装置的场景为例进行说明，当然，在另外一些示例中，也可以将后置摄像头装置作为前置摄像头装置来使用。
如图2和图3所示，后盖120、中框130与显示屏110包围形成容置空间，摄像头装置200的至少部分结构位于容置空间中，以减少摄像头装置200凸出于手机外部的体积，降低摄像头装置200对手机外观的影响。例如，摄像头装置200可以部分位于容置空间中，或者，摄像头装置200可以完全位于容置空间中。本申请实施例以摄像头装置200完全容置于容置空间中为例进行说明。
继续参考图3，后盖120上设置有安装孔121，安装孔121可以位于后盖120的边缘位置或者后盖120的中间位置。摄像头装置200位于后盖120、边框131和显示屏110围成的容置空间中，并通过安装孔121采光。后盖120与摄像头装置200之间可以采用泡棉或背胶等材料进行密封处理，以保证手机的密封性。需要说明的是，安装孔121的位置包括但不限于本实施例中的附图中所示的位置，在另外一些实施例中，还可以将安装孔121设置在其他位置，示例性地，安装孔121的位置还可以位于边框131的任意一侧或边框131的拐角处。
以下对本申请实施例提供的摄像头装置200进行详细的说明。
可以理解的是，摄像头装置可以包括缩回状态(参见图7所示)，缩回状态即摄像头模组220未伸出摄像头装置，摄像头装置位于电子设备内部，摄像头装置的厚度较小，电子设备的整体厚度较低，摄像头装置对电子设备的外观影响较小。
摄像头装置还可以包括伸出状态(参见图11所示)，伸出状态即摄像头模组220沿后盖120背离显示屏110的方向伸出，摄像头模组220朝背离承载件210的方向运动。此时，摄像头装置的厚度增大，其光学可用空间较大，能够获得较好的拍摄质量。这样通过将摄像头装置设计成可以伸缩的结构，以使摄像头装置的厚度不再受电子设备的厚度的限制，从而可以解决摄像头外凸的问题，并且电子设备的厚度可以设置得较小，有利于电子设备的轻薄化。
当然，摄像头装置还可以处于伸出状态和缩回状态之间的任意状态(即受到外力冲击后的缓冲状态)。
如图4所示，摄像头装置可以包括承载件210、驱动组件280、升降机构230、密封组件270、摄像头托架240以及设置在摄像头托架240内的摄像头模组220(参见图5)，驱动组件280和升降机构230传动连接，且驱动组件280和升降机构230以及摄像头托架240均设置在承载件210上。驱动组件280用于驱动升降机构230带动摄像头托架240升降，由于摄像头模组220设置在摄像头托架240内，所以摄像头托架240的升降可以带动摄像头模组220升降，以使摄像头模组220伸出和缩回电子设备中。
为了方便描述，在本实施例中，如图2所示，坐标系中直线X的箭头所指的方向为手机的宽度方向，直线Y的箭头所指的方向为手机的长度方向；带箭头的直线Z的箭头所指 的方向为手机的厚度方向以及旋转筒和升降筒以及导杆的中心轴线的方向。手机的方向与摄像头装置、驱动组件280和摄像头模组220等的方向可以一致。
需要说明的是，摄像头模组220的升降方向可以包括但不限于X方向、Y方向或Z方向。本申请实施例以Z方向为摄像头模组220的升降方向为例进行说明。即，在本实施例中，当摄像头装置拍摄时，摄像头模组220会朝向远离显示屏110的方向运动，从而伸出电子设备；当摄像头装置无需拍摄时，摄像头模组220朝向靠近显示屏110的方向运动，从而缩回电子设备。
在本实施例中，驱动组件280可以包括但不限于为电动、气动、液压、蜗杆传动、齿轮传动、电磁传动、电-液传动、气-液传动、电磁-液动等方式，以驱动升降机构230带动摄像头托架240沿Z方向往复运动。
其中，摄像头模组220可以包括镜头(图中未示出)，镜头可以包括镜筒和位于镜筒内的多个镜片，镜片可以为塑料透镜(Plastic)和玻璃透镜(Glass)中的至少一种。另外，摄像头模组220还可以包括对焦马达(图中未示出)，对焦马达位于镜头朝向承载件210的一侧，对焦马达用于调整焦距。可以理解的是，图中的摄像头模组220仅为一个参考图，并不构成对本申请实施例中摄像头模组220形状的限定。
需要说明的是，镜头根据镜片的数量可以包括5P镜头(5个镜片)、6P镜头等(6个镜片)。例如，5P镜头可以为5个塑料透镜，也可以为4个塑料透镜和1个玻璃透镜；6P镜头可以为6个塑料透镜，也可以为5个塑料透镜和1个玻璃透镜。需要说明的是，镜头中的镜片数量不限于5个或6个，还可以为大于等于2的任意数量。
如图5所示，摄像头装置可以包括透光件292、保护盖291、密封组件270、摄像头模组220、摄像头托架240承载件210和驱动组件280。其中，保护盖291的中间区域可以设置有透光孔2911，透光孔2911处覆盖有透光件292，镜头与透光件292沿Z方向相对设置。这样，在拍摄时，外部光线可以通过透光件292进入镜头中。透光件292可以通过卡接、粘接等方式连接在保护盖291上，示例性地，透光件292可以通过点胶或背胶与保护盖291固定连接。
如图6所示，驱动组件280和升降机构230设置在摄像头模组220的一侧，并且在摄像头模组220的外侧还设置有导向组件250，两个导向组件250相对设置在摄像头模组220的两侧，并且与升降机构230间隔设置。当然，在另外一些实施例中，导向组件250的数量还可以为一个、三个、四个或者更多，对于导向组件250的数量在本申请实施例中是不限制的。
结合图5和图6所示，摄像头托架240远离承载件210的一端设置有用于安装摄像头模组220的凸沿243，凸沿243围绕摄像头托架240向内延伸，摄像头模组220可以通过卡接、粘接等方式连接在摄像头托架240上，示例性地，摄像头模组220可以通过点胶或背胶固定在摄像头托架240内的凸沿243上。
承载件210上可以设置有镂空区域214，在镂空区域214可以设置光器件，示例性地，可以在镂空区域214设置滤光片，其中滤光片和摄像头模组220沿Z方向相对设置。示例性的，滤光片可以为红外滤光片，滤光片可以将红外光线进行滤除，防止红外光线进入镜头对成像造成影响。
在镂空区域214的外侧设置有朝向摄像头模组220延伸的凸壁211，摄像头托架240 设置在凸壁211的外侧，通过在承载件210上设置凸壁211，可以防止摄像头托架240沿着摄像头托架240的径向偏移，从而保证摄像头托架240的稳定性，进而保证摄像头装置的稳定性。在本实施例中，驱动组件280和摄像头模组220可以位于承载件210的同一侧，从而可以使得驱动组件280和摄像头模组220在手机的厚度方向上具有重叠部分，以降低摄像头装置的整体厚度。
如图7所示，保护盖291设置在摄像头托架240的外侧，透光件292与摄像头模组220远离承载件210的一端接触连接，且透光件292的外侧与保护盖291固定连接，以使保护盖291可以围设在摄像头托架240、部分承载件210以及升降机构230的外侧；保护盖291的边缘向靠近承载件210的方向延伸，以围设在摄像头托架240以及部分升降机构230的外周。其中，保护盖291对位于保护盖291内侧的结构部件起到保护作用。
在保护盖291的外侧还可以设置密封组件270，密封组件270包括第一密封件271和第二密封件272；其中，第一密封件271围设在保护盖291的顶端，且第一密封件271与保护盖291间隙配合；第二密封件272的一端与保护盖291靠近承载件210的一端密封连接，另一端与第一密封件271的外侧密封连接。这样可以防止从第一密封件271和保护盖291之间进入的灰尘以及水渍等从保护盖291和限位件之间进入摄像头装置的内部，从而对摄像头装置起到一定的保护作用，进而延长摄像头装置的使用寿命。
需要说明的是，密封组件270的外侧边缘可以固定设置在电子设备100的后盖120上，并且与电子设备100的后盖120密封连接，密封组件270的内侧边缘包括第一密封件271的内侧边缘和第二密封件272的内侧边缘，其中，第一密封件271的内侧边缘和保护盖291之间为间隙配合，这样可以保证摄像头装置可以相对于密封组件270升降运动，进而使摄像头装置可以在伸出状态和缩回状态切换。
在一些实施例中，第二密封件272的材料设置为软质材料，以使摄像头模组220在伸出和缩回时，第二密封件272可以方便的跟随保护盖291升降移动。在本实施例中，对于第二密封件272的材质不作具体限定。
结合图7和图8所示，升降机构230可以包括第一滚轮231和第二滚轮232，第二滚轮232与驱动组件280传动连接，第二滚轮232与第一滚轮231传动连接；第二滚轮232用于将驱动组件280的驱动力传递至第一滚轮231，以驱动第一滚轮231旋转。
通过将升降机构230设置成包括第一滚轮231和第二滚轮232的结构，可以提高第一滚轮231设置位置的灵活性，这样就可以降低第一滚轮231的设置难度，进而简化第一滚轮231的结构，降低摄像头装置的加工成本。
当然，在一些实施例中，也可以不设置第二滚轮232，示例性地，直接将第一滚轮231与驱动组件连接，这样可以使升降机构的结构更加简单。而在另外一些实施例中，升降机构230还可以包括N个第三滚轮(图中未示出)，N为大于或等于1的整数，第三滚轮设置在第二滚轮和第一滚轮之间，第三滚轮用于将第二滚轮和第一滚轮传动连接，示例性地，可以设置一个、两个、三个或更多个第三滚轮。
这样通过在第二滚轮232和第一滚轮231之间设置N个第三滚轮，这样可以使驱动组件280的传动力经过多级传动后到达第一滚轮231，由于多级传动可以改变第一滚轮231的驱动力以及旋转速度，所以这样可以改变升降机构230的驱动力，以及摄像头托架240的升降速度。另外，通过设置多个第三滚轮，可以方便与摄像头托架240接触连接的第一 滚轮231的设置，例如，在驱动组件280距离摄像头托架240较远的情况下，或者是在设置角度不合适的情况下，均可以通过增加第三滚轮的方式，使摄像头托架240可以和升降机构230中的第一滚轮231相配合，当然，升降机构230中的第三滚轮的数量可以根据具体情况具体设定，在本实施例中，不做具体限定。
在本实施例中，承载件210设置驱动组件280的一面可以设置安装座212；安装座212的底端固定在承载件210上，示例性地，安装座212可以通过卡接、铆接、粘接等方式固定在承载件210上。安装座212的顶端沿摄像头托架240的轴向向远离承载件210的方向延伸；升降机构230转动设置在安装座212上，示例性地，升降机构230与安装座212之间可以通过轴承实现转动连接。
通过设置安装座212可以为升降机构230的设置提供位置，以使升降机构230固定在承载件210上；另外，通过将升降机构230与安装座212转动连接，以使升降机构230可以相对于承载件210旋转，进而带动摄像头托架240沿着摄像头托架240的轴向升降。
如图9所示，安装座212的顶端设置有第一安装部2121，第一滚轮231转动设置在第一安装部2121上；安装座212的底端设置有第二安装部2122，第二滚轮232转动设置在第二安装部2122上。第二安装部2122靠近驱动组件280设置，这样可以方便驱动组件280和第二滚轮232之间的传动连接，可以减少驱动组件280和第二滚轮232之间的传动部件，进而简化摄像头装置的结构。
第一安装部2121上设有用于容纳第一滚轮231的开口2123；第一滚轮231的两端均设有连接杆2311，连接杆2311的直径小于第一滚轮231的直径；第一滚轮231位于开口2123内，第一滚轮231的两端通过连接杆2311与第一安装部2121转动连接，以使第一滚轮231与摄像头托架240的侧壁(即导向板241)抵接；第二滚轮232和第一滚轮231之间通过传动装置233传动连接，且第一滚轮231上的传动装置233设置在连接杆2311上。在本实施例中，第一滚轮231和第二滚轮232之间的传动装置233可以为阻尼线、传动带、链条等，具体可以根据具体情况设定，在本实施例中不作具体限定。
通过在第一安装部2121上设置开口2123结构，以保证第一滚轮231可以和摄像头托架240的侧壁抵接；通过在第一滚轮231的两端均设有连接杆2311，且连接杆2311的直径小于第一滚轮231的直径，这样可以为传动装置233的设置提供安装位置，并且这样传动装置233的设置不会影响第一滚轮231和摄像头托架240抵接。
结合图5图7和图8所示，导向组件250可以包括导向柱251以及围设在导向柱251外侧的升降滑板252，其中，导向柱251垂直设置于承载件210上，升降滑板252设置在摄像头托架240上，且升降滑板252围设在导向柱251的外侧，并与导向柱251滑动连接。
其中，升降滑板252与摄像头托架240之间可以通过卡接、粘接、焊接、一体成型等方式连接，示例性地，可以通过点胶或背胶实现固定连接，对于升降滑板252和摄像头托架240之间的固定方式在本实施例中是不限制的。导向柱251和承载件210之间可以采用粘接、焊接、卡接、一体成型、螺纹连接等方式连接，对于导向柱251和承载件210之间的固定方式在本申请实施例中是不限制的。
通过设置导向柱251和升降滑板252，并且将升降滑板252设置在摄像头托架240上，将导向柱251设置在承载件210上，以使摄像头托架240可以带动升降滑板252沿着导向柱251滑动，以使摄像头托架240可以沿着摄像头托架240的轴向垂直升降。
在一些实施例中，导向柱251和降滑板之间还可以设置有多个滚珠253，这样在摄像头托架240的升降过程中可以减小导向柱251和升降滑板252之间的摩擦力，从而减小摄像头托架240升降的阻力，从而可以节约驱动组件280的能量。
另外，结合图8和图10所示，在摄像头托架240与升降机构230抵接的一侧设置有导向板241，在导向板241靠近升降机构230的一侧设置有摩擦面242，其中，摩擦面242与第一滚轮231接触连接，进而可以提高第一滚轮231和摄像头托架240之间的滚动摩擦，以保证第一滚轮231旋转可带动摄像头托架240升降运动。可以理解的是，在摄像头的升降过程中，第一滚轮231与摄像头托架240上的摩擦面242均抵接，也就是说，摩擦面242可以覆盖摄像头托架240的整个行程，即摩擦面242的长度大于或等于摄像头托架240的最大行程。
摩擦面242可以通过卡接、粘接、一体成型等方式与摄像头托架240连接，在本实施例中，对于摩擦面242和摄像头托架240的连接方式不作具体限定。
安装座212与摄像头托架240的导向板241间隙配合，第一滚轮231与导向板241抵接，以使摄像头托架240能够相对于安装座212沿着Z向滑动。
本实施例中，导向板241的数量为两个，并且两个导向板241相对设置，通过设置导向板241可以防止摄像头托架240在升降过程中产生旋转，还可以对摄像头托架240的升降起到导向作用，以使摄像头托架240垂直升降；另外还可以为摩擦面242的设置提供位置，进而降低摩擦面242的设置难度。当然，在不与升降机构230抵接的导向板241上可以不设置摩擦面242。
在本实施例中，摩擦面242的材质可以为软胶面，示例性地，可以为聚丙烯、聚乙烯、硅胶等软质材料，这样可以增加第一滚轮231和摄像头托架240的摩擦力。
需要说明的是，在一些实施例中，还可以将摩擦面242直接设置在第一滚轮231上，示例性的，可以在第一滚轮231的外表面围设一层摩擦面242，这样也可以在摄像头托架240升降的过程中增加摩擦力。
需要说明的是，驱动组件280和升降机构230的数量包括但不限于一个，也可以设置两个驱动组件280和两个升降机构230，示例性地，摄像头装置可以包括两个驱动组件280和两个升降机构230，其中，一个驱动组件280对应一个升降机构230；两个驱动组件280相对设置在摄像头托架240的两侧，同样的两个升降机构230也设置在摄像头托架240的两侧，以使一个驱动组件280对应一个升降机构230；摄像头托架240上的导向板241也设置有两个，并且两个导向板241相对设置在摄像头托架240的两侧，并且导向板241与第一滚轮231接触连接，每个导向板241朝向第一滚轮231的一侧均可以设置摩擦面242，以使旋转第一滚轮231可以带动摄像头托架240升降。设置两个驱动组件280和两个升降机构230，这样可以使摄像头托架240的受力均匀，从而可以提高摄像头装置升降过程的稳定性。
以下对本申请实施例提供的摄像头模组220沿Z方向升降运动进行的说明。
示例性地，下面以摄像头装置的初始位置为缩回状态对摄像头装置的升降过程进行说明。
如图7所示，摄像头装置处于缩回状态，此时摄像头托架240的底端位于承载件210上，且摄像头托架240的顶端位于密封组件270顶端端面之内。驱动组件280、升降机构 230、摄像头托架240均设置在承载将上，且驱动组件280、升降机构230、摄像头托架240均位于承载件210的同一侧。升降机构230包括第一滚轮231和第二滚轮232，其中，第二滚轮232与驱动组件280传动连接，第二滚轮232和第一滚轮231之间传动连接；第二滚轮232靠近承载件210设置，第一滚轮231刀承载件210的距离大于第二滚轮232到承载件210的距离；第一滚轮231靠近摄像头托架240设置，并与摄像头托架240的导向板241抵接，导向板241靠近第一滚轮231的一侧设置有摩擦面242，第一滚轮231与摩擦面242抵接。
当第一滚轮231沿第一方向旋转时，可以带动摄像头托架240沿着Z向向远离承载件210的方向移动，以使摄像头托架240带动这摄像头模组220、透光件292以及保护盖291向远离承载件210的方向移动，进而使摄像头装置从缩回状态到达伸出状态(如图11所示)。
如图11所示，摄像头托架240处于伸出状态，即摄像头装置处于伸出状态，此时摄像头托架240以及设置在摄像头托架240上的摄像头模组220、透光件292以及保护盖291均伸出电子设备之外。此时，当第一滚轮231沿第二方向旋转时，可以带动摄像头托架240沿着Z向向靠近承载件210的方向移动，以使摄像头托架240带动这摄像头模组220、透光件292以及保护盖291向靠近承载件210的方向移动，进而使摄像头装置伸出状态从到达缩回状态。
需要说明的是，摄像头装置依靠第一滚轮231和摩擦面242之间的滚动摩擦力，实现了摄像头托架240沿Z向的升降。
需要说明的是，第一方向和第二方向相反，示例性地，第一方向为逆时针，第二方向为顺时针。
当然，第一滚轮231和第二滚轮232的旋转方向可以相同，也可以不同，具体可以根据传动装置233的缠绕方向确定；驱动组件280的旋转方向可以和第二滚轮232相同，也可以不同，具体可以根据驱动组件280和第二滚轮232之间的连接关系确定，在本实施例中不作具体限定。
可以理解的是，通过控制驱动组件280正转和反转可以使第二滚轮232沿着不同的方向旋转，而第二滚轮232沿着不同的方向旋转可以带动第一滚轮231沿着不同的方向旋转，进而使摄像头托架240沿Z向升降。在本实施例中，正转可以为第一方向，即逆时针方向，反转可以为第二方向，即顺时针方向。
在本实施例中，驱动组件280在摄像头装置到达伸出状态或缩回状态时可以自动停止旋转，从而防止摄像头托架240从承载件210上脱落。另外，驱动组件280还可以在摄像头装置在伸出状态和缩回状态之间时，将摄像头装置调节到伸出状态或缩回状态。
下面具体介绍摄像头装置的缓冲功能。
在本实施例中，如图11所示，摄像头装置受到的外力F冲击时，首先会作用在透光件292上，而透光件292设置在保护盖291和摄像头模组220上，摄像头模组220设置在托架组件上，所以在摄像头装置受到的外力F冲击，通过透光件292作用在摄像头模组220上，然后通过摄像头模组220作用在摄像头托架240上。由于第一滚轮231和摄像头托架240之间是通过滚动摩擦实现的连接关系，所以在摄像头托架240受到外力F冲击时，这种滚动摩擦连接关系会被破坏，会使滚动摩擦变成滑动摩擦，从而使摄像头托架240会和第一滚轮231之间产生滑动，由于第一滚轮231沿Z沿固定，所以摄像头托架240会沿着 Z向向靠近承载件210的方向移动，进而缓冲摄像头模组220受到的外力F冲击。并且整个缓冲过程中，不会对升降机构230造成冲击，从而可以解决相关技术中受到外力F冲击造成升降机构230损坏的问题。
在本申请实施例中，无需单独设置缓冲机构，就可以实现摄像头的缓冲功能，可以使摄像头装置的结构更加简单，进而降低摄像头装置的成本。另外，只要摄像头模组220要伸出、正在伸出或者已经伸出电子设备，无论是摄像头模组220向外伸出的过程，还是向内缩回的过程，或者正常工作状态，均可以依靠自身特殊结构实现缓冲功能，从而可以实现摄像头模组220运动过程以及工作过程的全程缓冲，对摄像头模组220的保护效果较好。
本申请实施例中的摄像头装置还可以包括控制组件260，其中，控制组件260与驱动组件280电连接；控制组件260用于监测摄像头托架240的位置，并根据摄像头托架240的位置控制驱动组件280旋转，以使摄像头托架240位于伸出状态或缩回状态。
通过设置控制组件260可以使摄像头组件在伸出状态和缩回状态之间时，自动回到伸出状态或者缩回状态。因为在摄像头装置位于伸出状态时如果受到外力冲击，会使摄像头托架240带动这摄像头模组220向靠近承载件210的方向滑动，这样摄像头装置就位于伸出状态和缩回状态之间，这样会影响摄像头装置的正常使用，通过设置控制组件260，在摄像头装置就位于伸出状态和缩回状态之间时，控制组件260就可以通过监测到摄像头托架240的位置使驱动组件280启动，并将摄像头装置调整至伸出状态或缩回状态，以方便下次使用。
如图12所示，控制组件260包括两个距离监测组件261；其中，两个距离监测组件261间隔设置，且两个距离监测组件261之间的距离h为摄像头托架240沿摄像头托架240的轴向升降的最大行程。通过设置两个距离监测组件261，并将两个距离监测组件261之间的距离设置为摄像头托架240沿摄像头托架240的轴向升降的最大行程，可以提高监测到的摄像头托架240位置的准确性。
在一种可能的实现方式中，每个距离监测组件261均包括霍尔器件262和磁性件263；其中，霍尔器件262与磁性件263相对设置，且霍尔器件262和磁性件263中的其中一个设置在承载件210上，霍尔器件262和磁性件263中的其中另一个设置在摄像头托架240上，霍尔器件262用于监测磁性件263的位置；霍尔器件262与驱动组件280电连接，以使驱动组件280接收到霍尔器件262监测到的信号后旋转，并将摄像头托架240调节至伸出状态或缩回状态。
需要说明的是，同一个距离监测组件261中的霍尔器件262可以同时监测不同距离监测组件261中的磁性件263，并且在磁性件263到霍尔器件262之间的距离小于预设阈值时，霍尔器件262将信号传递至驱动组件280，驱动组件280接收到霍尔器件262监测到的信号后旋转，并将摄像头托架240调节至伸出状态或缩回状态。
示例性地，霍尔器件262设置在承载件210上，且位于承载件210的安装座212上，安装座212上设置有容纳霍尔器件262的第一凹槽，以使霍尔器件262可以隐藏设置在安装座212上，从而使霍尔器件262不会影响摄像头托架240的升降，其中，霍尔器件262可以通过卡接、粘接、焊接等方式固定在第一凹槽内，霍尔器件262和安装座212的固定方式在本实施例中是不限定的；磁性件263设置在摄像头托架240靠近安装座212的一侧，在摄像头托架240靠近安装座212的一侧设置有用于安装磁性件263的第二凹槽，以使磁 性件263隐藏设置在摄像头托架240上，进而防止磁性件263对摄像头的升降造成影响，其中，磁性件263可以通过卡接、粘接、焊接等方式固定在第二凹槽内，磁性件263和摄像头托架240之间的固定方式在本实施例中是不限定的。
下面对控制组件260对驱动组件280的控制过程进行介绍。
为了方便描述，在本实施例中，两个距离监测组件261分别为第一距离监测组件261a和第二距离监测组件261b，其中，第一距离监测组件261a包括第一霍尔器件262a和第一磁性件263a，第二距离监测组件261b包括第二霍尔器件262b和第二磁性件263b。
如图13所示，在摄像头装置处于缩回状态时，第一霍尔器件262a和第一磁性件263a相对设置，第二霍尔器件262b和第二磁性件263b相对设置，此时，第一磁性件263a到第一霍尔器件262a以及第二磁性件263b到第二霍尔器件262b的距离均小于预设阈值，第一霍尔器件262a可以监测到第一磁性件263a，第二霍尔器件262b可以监测到第二磁性件263b，此时，两个霍尔器件262均可以监测到磁性件263，控制组件260控制驱动组件280不转动。
如图14所示，当摄像头装置处于伸出状态时，第一霍尔器件262a与第二磁性件263b相对设置，第二磁性件263b到第一霍尔器件262a的距离小于预设阈值，第一霍尔器件262a可以监测到第二磁性件263b，第一磁性件263a到第一霍尔器件262a和第二霍尔器件262b的距离均超过预设阈值，所以第二霍尔器件262b无法监测到磁性件263，此时，两个霍尔器件262中监测到一个磁性件263，控制组件260控制驱动组件280也不转动。
如图15所示，当摄像头状态处于伸出状态和缩回状态之间时(即摄像头装置受到外力冲击后，摄像头托架240相对于第一滚轮231向靠近承载件210的方向移动的状态)，第一磁性件263a和第二磁性件263b到第一霍尔器件262a的距离均大于预设阈值，第一磁性件263a和第二磁性件263b到第二霍尔器件262b的距离也均大于预设阈值，此时，第一霍尔器件262a和第二霍尔器件262b均监测不到磁性件263，控制组件260控制驱动组件280转动，并将摄像头托架240调节至伸出状态或缩回状态。
需要说明的是，控制组件260控制驱动组件280的判断条件包括但不限于上述实施例中的霍尔器件262监测到的磁性件263的数量，在另外一些实施例中，还可以将其他信息设置成控制驱动组件280的判断条件，因此，在本实施例中对于控制组件260控制驱动组件280的判断条件不作具体限定。
另外，上述实施例中的预设阈值可以根据霍尔器件262的不同型号设置成不同的值，具体可以根据具体情况设置，在本实施例中不作具体限定。
通过将距离监测组件261设置为包括霍尔器件262和磁性件263的结构，可以方便地将距离监测组件261设置在摄像头装置上，并且霍尔器件262和磁性件263的结构简单，对摄像头装置的体积以及重量影响较小。
在本申请实施例中，驱动组件280包括但不限于马达，其中，马达的型号不构成对本申请实施例保护范围的限制，马达的具体型号可以根据具体需求选择，在本实施例中不作具体限定。另外，驱动组件280可以位于摄像头托架240的外侧，从而能够使得摄像头托架240的体积较小，有利于摄像头装置的小型化。当然的，驱动组件280可以位于摄像头托架240的内侧，从而对驱动组件280起到保护作用。
在本申请实施例的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、 “相连”、“连接”应作广义理解，例如，可以是固定连接，也可以是通过中间媒介间接相连，可以是两个元件内部的连通或者两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请实施例中的具体含义。
术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
最后应说明的是：以上各实施例仅用以说明本申请实施例的技术方案，而非对其限制；尽管参照前述各实施例对本申请实施例进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请实施例各实施例技术方案的范围。
