电子设备以及壳体组件
本申请要求于2022年03月10日提交中国专利局、申请号为202210240793.9、申请名称为“电子设备以及壳体组件”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及终端技术领域,特别涉及一种电子设备以及壳体组件。
背景技术
随着社会的发展,智能手机或平板电脑等电子设备广泛应用于人们的日常生活。电子设备为人们提供娱乐、社交或办公等功能。由于人们对电子设备的功能需求越来越多,因此电子设备自身的功能越来越多。例如,人们对电子设备的摄像性能要求越来越高,期望可以获得高分辨率的图像。为了满足拍摄需求,电子设备中后置的功能器件的数量和种类越来越多。功能器件可以用于拍照、感光或照明等用途。例如,功能器件为具有满足拍照功能的摄像模组时,为了获得清晰度较高的图像,摄像模组自身的尺寸会较大。电子设备对整体的轻薄化有需求,自身整体厚度和重量需要满足使用要求。然而,由于摄像模组自身的尺寸较大,需要预留足够的安装空间容纳摄像模组并且保证摄像模组可以正常工作,因此电子设备上设置摄像模组的区域设置为凸出结构,从而在使用摄像模组实现相应功能的同时也兼顾电子设备的外观美观度。但是,电子设备凸出的结构,影响电子设备的整体外观,也因背面高低不平整,影响电子设备放置或收纳,影响使用体验满意度。
发明内容
本申请实施例提供一种电子设备以及壳体组件,可解决摄像模组对应区域存在凸出影响美观度和使用便利性的问题。
本申请第一方面提供一种电子设备,其至少包括壳体组件和摄像模组。壳体组件包括壳体和活动支架。壳体具有相互连通的避让孔和容纳腔。避让孔贯穿壳体。活动支架对应避让孔设置。活动支架包括透光部。活动支架可移动连接于壳体,以通过避让孔伸出容纳腔外形成避让空间或缩回容纳腔内。摄像模组固定设置于容纳腔内,并且摄像模组的进光部与透光部相对。活动支架与摄像模组相互独立设置。摄像模组包括镜片组件。镜片组件整体或镜片组件中靠近活动支架的至少一个镜片可在避让空间内移动。
本申请实施例提供的电子设备包括壳体组件和摄像模组。壳体组件包括壳体和活动支架。活动支架可以相对壳体移动,以通过避让孔伸出容纳腔外形成避让空间或缩回容纳腔内。摄像模组包括镜片组件。在摄像模组处于工作状态,镜片组件整体或者靠近活动支架的至少一个镜片需要伸出执行对焦动作时,活动支架伸出壳体的容纳腔,从而增大透光部和摄像模组之间的距离,为伸出的镜片组件提供避让空间,使得透光 部和镜片组件不发生位置干涉。在摄像模组处于非工作状态,镜片组件处于缩回状态时,活动支架缩回壳体的容纳腔,从而活动支架不凸出于壳体的外表面,保证电子设备的外表面具有较好的平整度,有利于提高电子设备的外观美观度和一致性。
在一种可能的实施方式中,电子设备还包括驱动组件。驱动组件设置于容纳腔内。驱动组件具有固定端和活动端。驱动组件的固定端与壳体相连。驱动组件的活动端与活动支架相连。驱动组件通过活动端驱动活动支架相对壳体沿避让孔的轴向移动。驱动组件可以通过采用电气控制的方式控制活动支架实现伸出或缩回,有利于实现活动支架的自动化控制,提高活动支架的位置移动精度,也可以保证活动支架的运动与摄像模组的镜片组件的运动同步性。
在一种可能的实施方式中,驱动组件包括至少一组第一驱动单元和至少一组第二驱动单元。第一驱动单元和第二驱动单元相互独立设置。第一驱动单元驱动活动支架伸出容纳腔。第二驱动单元驱动活动支架缩回容纳腔。第一驱动单元和第二驱动单元可以各自独立工作,不存在运动干涉的情况。第一驱动单元和第二驱动单元各自的驱动方式可以相同,也可以不同,从而有利于提高驱动方式选择灵活性和多样性,提高第一驱动单元或第二驱动单元结构设计灵活性,以适应不同的安装空间和应用场景。
在一种可能的实施方式中,第一驱动单元包括至少一个第一电致伸缩体。第一电致伸缩体收缩时,第一驱动单元对活动支架施加作用力,以驱动活动支架伸出容纳腔外。由于第一驱动单元的第一电致伸缩体可以用于产生驱动活动支架移动的动力,而第一电致伸缩体自身的体积可以设计的较小,因此第一驱动单元整体的结构设计可以更加紧凑,从而第一驱动单元整体占用较小的空间,有利于容纳腔释放更多的空间布置更多的结构件或者有利于电子设备轻薄化设计。
在一种可能的实施方式中,第一电致伸缩体的一端与壳体连接,另一端与活动支架连接。第一电致伸缩体通过自身收缩可以直接驱动活动支架,从而第一电致伸缩体和活动支架之间可以不需要额外设置传动结构,有利于简化第一电致伸缩体和活动支架之间的结构设计。第一电致伸缩体和活动支架之间传动链较短,有利于提高第一电致伸缩体和活动支架之间的传动效率,也有利于减小误差累积,提高活动支架自身的位置移动精度。
在一种可能的实施方式中,第一电致伸缩体的一端与壳体朝向容纳腔的内壁连接,另一端与活动支架位于容纳腔内且远离壳体的端部连接,从而可以增大固定端和活动端之间的距离,从而可以增大第一电致伸缩体自身的长度,有利于在有限的空间内增大第一电致伸缩体的收缩量,以增大活动支架的位移量。
在一种可能的实施方式中,每组第一驱动单元包括两个第一电致伸缩体。两个第一电致伸缩体在第一平面上的投影相交或投影的延长线相交。第一平面为垂直于轴向的平面。两个第一电致伸缩体同时对活动支架施加驱动力,有利于保证活动支架受力平衡,提高移动过程的稳定性。

在一种可能的实施方式中,第一致动件包括两个第一杆件。一个第一杆件可转动连接于另一个第一杆件。第一杆件具有良好的刚性。第一致动件采用自身不易发生变形的杆件结构,可以有利于提高第一致动件的载荷,降低第一致动件自身发生意外变形而导致活动支架移动后的位置存在偏差的可能性。
在一种可能的实施方式中,沿避让孔的轴向,第一电致伸缩体的两侧分别设置第一致动件。第一电致伸缩体的收缩量可以通过两侧的第一致动件进行放大,使得活动支架的位移量大于第一电致伸缩体的收缩量,有利于使用长度较短的第一电致伸缩体即可驱动活动支架获得较大的位移量。

在一种可能的实施方式中,第二驱动单元包括至少一个第二电致伸缩体。第二电致伸缩体收缩时,第二驱动单元对活动支架施加作用力,以驱动活动支架缩回容纳腔。由于第二驱动单元的第二电致伸缩体可以用于产生驱动活动支架移动的动力,而第二电致伸缩体自身的体积可以设计的较小,因此第二驱动单元整体的结构设计可以更加紧凑,从而第二驱动单元整体占用较小的空间,有利于容纳腔释放更多的空间布置更多的结构件或者有利于电子设备轻薄化设计。
在一种可能的实施方式中,第二电致伸缩体的一端与壳体连接,另一端与活动支架远离摄像模组的端部连接。第二电致伸缩体通过自身收缩可以直接驱动活动支架,从而第二电致伸缩体和活动支架之间可以不需要额外设置传动结构,有利于简化第二电致伸缩体和活动支架之间的结构设计。第二电致伸缩体和活动支架之间传动链较短,有利于提高第二电致伸缩体和活动支架之间的传动效率。也有利于减小误差累积,提高活动支架自身的位置移动精度。
在一种可能的实施方式中,壳体包括转接部。转接部位于活动支架靠近摄像模组的一侧。第二电致伸缩体的一端与转接部连接,另一端与活动支架连接,从而可以有利于增大第二电致伸缩体的长度,使得第二电致伸缩体收缩时可以获得相对较大的收缩量,而活动支架可以获得相对较大的位移量。
在一种可能的实施方式中,每组第二驱动单元包括两个第二电致伸缩体。两个第二电致伸缩体在第一平面上的投影相交或投影的延长线相交。第一平面为垂直于避让孔的轴向的平面。第二电致伸缩体的收缩时,两个相交设置的第二电致伸缩体同时对 活动支架施加驱动力,有利于保证活动支架受力平衡,提高移动过程的稳定性。

壳体组件30的壳体31具有避让孔31b。避让孔31b贯穿壳体31,以连通壳体31的外部环境和容纳腔31a。壳体组件30还包括活动支架32。活动支架32对应壳体31的避让孔31b设置。活动支架32可以与壳体31的避让孔31b插接配合,例如,活动支架32与避让孔31b之间可以是间隙配合。壳体31的避让孔31b用于避让活动支架32,从而使得壳体31和活动支架32之间不存在位置干涉。活动支架32可移动连接于壳体31,以通过避让孔31b伸出容纳腔31a外形成避让空间或缩回壳体31的容纳腔31a内。需要说明的是,摄像模组60具有进光部。在一些示例中,镜片组件62中最靠近活动支架32的镜片或者棱镜为进光部。
活动支架32受到壳体31的限位约束,活动支架32在避让孔31b的轴向X上具有活动自由度。需要说明的是,避让孔31b的轴向X可以为避让孔31b的延伸方向。示例性地,避让孔31b的横截面形状可以是圆形、椭圆形或者多边形,本申请对此不作限定。在一些可实现的方式中,活动支架32受到沿避让孔31b的轴向X的作用力时,活动支架32可以沿避让孔31b的轴向X相对壳体31移动,以通过避让孔31b伸出容纳腔31a外形成避让空间或缩回壳体31的容纳腔31a内。在另一些实现方式中,活动支架32不一定沿避让孔31b的轴向X相对壳体31移动,也可以有一定偏移,只要能够从容纳腔31a中伸出避让孔31b即可,因此,活动支架32受到的作用力也不一定完全沿避让孔31b的轴向X,只要有沿避让孔31b的轴向X的分量即可实现。后文中主要以前一种实现方式为例进行说明,但可以理解的,本申请并不局限于该中实现方式。
图3示意性地显示了本申请一实施例的包括处于缩回位置的活动支架32的电子设备10的局部剖视结构。参见图3所示,活动支架32缩回壳体31的容纳腔31a时,活动支架32具有缩回位置。在一些示例中,活动支架32在缩回位置时,活动支架32的外表面可以与壳体31的外表面平齐,从而活动支架32不凸出于壳体31的外表面,保证电子设备10的背面平整,有利于提高电子设备10的外观美观度和一致性。活动支架32伸出壳体31的容纳腔31a时,图4示意性地显示了本申请一实施例的包括处于伸出位置的活动支架32的电子设备10的局部剖视结构。参见图4所示,活动支架32具有伸出位置。活动支架32的一部分凸出壳体31背向摄像模组60的外表面。在一些示例中,在伸出位置或者缩回位置,活动支架32仍然与壳体31保持连接状态。
参见图4所示,活动支架32包括具有透光性能的透光部321。摄像模组60的进光部与透光部321相对。摄像模组60的进光部用于接收光线。需要说明的是,在一些实施例中,当镜片组件62的第一片镜片为透镜时,镜片组件62的光轴方向可以与避 让孔31b的轴向X平行或重合;在另一些实施例中,当镜片组件62的第一片镜片为棱镜时,一般用于潜望式的摄像模组,因此镜片组件62的光轴方向在第一片镜片处会被转折90度,从而变为与避让孔31b的轴向X垂直。电子设备10外部的光线可以透过透光部321入射到摄像模组60的进光部处。活动支架32伸出或缩回壳体31的容纳腔31a,以使透光部321远离或靠近摄像模组60。在一些示例中,透光部321可以对应一个或两个以上的摄像模组60设置,本申请实施例对此不作限定。
参见图3所示,摄像模组60处于工作状态时,摄像模组60的镜片组件62可以沿避让孔31b的轴向X伸出执行对焦等动作。活动支架32伸出壳体31的容纳腔31a时,活动支架32的透光部321远离摄像模组60移动,使得透光部321和摄像模组60之间的间距增大,释放更大的空间以使得镜片组件62可以顺利伸出并且不与透光部321发生接触。需要说明的是,活动支架32伸出容纳腔31a外,透光部321和摄像模组60之间的间距增大后所释放出的空间形成避让空间。在一些示例中,镜片组件62整体或镜片组件62中靠近活动支架32的至少一个镜片可在避让空间内移动。参见图4所示,摄像模组60可以处于非工作状态。摄像模组60的镜片组件62可以处于缩回状态。活动支架32缩回壳体31的容纳腔31a时,活动支架32的透光部321靠近摄像模组60,使得透光部321和摄像模组60之间的间距减小。在一些示例中,活动支架32在缩回位置时,活动支架32的透光部321的外表面可以与壳体31的外表面平齐。本申请实施例中,活动支架32在缩回位置可以为初始位置。
本申请实施例中,活动支架32与摄像模组60相互独立设置,即活动支架32与摄像模组60之间无连接关系,使得活动支架32与摄像模组60处于解耦状态。活动支架32与摄像模组60之间无直接连接关系,也不通过其他结构件间接连接。活动支架32伸出或缩回的整个过程中,活动支架32相对摄像模组60运动,而摄像模组60的位置始终保持不变。活动支架32与摄像模组60之间不发生接触,不发生作用力的传递。在一些示例中,摄像模组60的外表面的任意位置与活动支架32之间具有间距,从而摄像模组60的外表面和活动支架32之间形成间隙,使得两者之间在任意位置不接触。
本申请实施例的电子设备10包括壳体组件30和摄像模组60。壳体组件30包括壳体31和活动支架32。活动支架32可以相对壳体31移动,以通过避让孔31b伸出容纳腔31a外形成避让空间或缩回容纳腔31a内。摄像模组60包括镜片组件62。在摄像模组60处于工作状态,镜片组件62整体或者靠近活动支架32的至少一个镜片需要伸出执行对焦动作时,活动支架32伸出壳体31的容纳腔31a,从而增大透光部321和摄像模组60之间的距离,为伸出的镜片组件62提供避让空间,使得透光部321和镜片组件62不发生位置干涉。在摄像模组60处于非工作状态,镜片组件62处于缩回状态时,活动支架32缩回壳体31的容纳腔31a,从而活动支架32不凸出于壳体31的外表面,保证电子设备10的外表面具有较好的平整度,有利于提高电子设备10的外观美观度和一致性。
另外,摄像模组60的镜片组件62对沿光轴方向的位置移动精度要求较高,因此如果镜片组件62的位置移动误差较大,会导致无法对焦或者对焦不准确的问题。本申请实施例中,由于活动支架32和摄像模组60相互独立设置,因此活动支架32的运动 和摄像模组60的镜片组件62的运动不存在关联,两者的运动互不干涉,从而使得活动支架32的位置移动误差不会向镜片组件62传递。由于活动支架32只需要保证透光部321远离摄像模组60以释放出更大的空间,因此活动支架32的位置移动精度要求相对较低,从而有利于降低活动支架32与壳体31的装配难度和装配精度要求。
再者,由于活动支架32和摄像模组60相互独立设置,因此活动支架32发生结构损坏需要维修或更换时,只需要将活动支架32以及壳体31拆除即可,不需要拆除、移动摄像模组60,从而可以有效降低因需要重新安装复位摄像模组60而导致摄像模组60的位置偏离原位置的可能性,降低电子设备10的检修难度和检修成本。
在一些可实现的方式中,参见图3和图4所示,电子设备10还包括驱动组件70。驱动组件70设置于壳体31的容纳腔31a内,从而从电子设备10的外部不易观察到驱动组件70,有利于提高电子设备10的美观度。驱动组件70连接壳体31和活动支架32。驱动组件70可以对活动支架32施加轴向作用力,从而可以驱动活动支架32相对壳体31移动。驱动组件70具有固定端和活动端。驱动组件70的固定端与壳体31相连。驱动组件70的活动端与活动支架32相连。驱动组件70通过活动端驱动活动支架32相对壳体31移动。在驱动组件70驱动活动支架32移动时,驱动组件70的活动端沿避让孔31b的轴向X移动,使得活动端相对固定端发生移动。
驱动组件70仅连接壳体31和活动支架32。驱动组件70与摄像模组60相互独立设置,即驱动组件70与摄像模组60之间无连接关系,使得驱动组件70与摄像模组60处于解耦状态。驱动组件70与摄像模组60之间不发生接触,不发生作用力的传递。驱动组件70可以通过采用电气控制的方式控制活动支架32实现伸出或缩回,有利于实现活动支架32的自动化控制,提高活动支架32的位置移动精度,也可以保证活动支架32的运动与摄像模组60的镜片组件62的运动同步性。
在一些可实现的方式中,图5示意性地显示了本申请一实施例的电子设备10的局部剖视结构。参见图4和图5所示,驱动组件70包括至少一组第一驱动单元71和至少一组第二驱动单元72。第一驱动单元71和第二驱动单元72相互独立设置,即第一驱动单元71和第二驱动单元72之间无连接关系。第一驱动单元71和第二驱动单元72可以各自独立工作,不存在运动干涉的情况。第一驱动单元71和第二驱动单元72各自的驱动方式可以相同,也可以不同,从而有利于提高驱动方式选择灵活性和多样性,提高第一驱动单元71或第二驱动单元72结构设计灵活性,以适应不同的安装空间和应用场景。
本申请实施例中,沿避让孔31b的轴向X,第一驱动单元71的固定端位于第一驱动单元71的活动端靠近避让孔31b的一侧。参见图5所示,活动支架32处于缩回位置。图6示意性地显示了本申请一实施例的电子设备10的局部剖视结构。参见图6所示,活动支架32处于伸出位置。在活动支架32需要从图5所示的缩回位置切换到图6所示的伸出位置时,第一驱动单元71可以驱动活动支架32伸出容纳腔31a。沿避让孔31b的轴向X,第二驱动单元72的固定端位于第二驱动单元72的活动端远离避让孔31b的一侧。在活动支架32需要从图6所示的伸出位置切换到图5所示的缩回位置时,第二驱动单元72可以驱动活动支架32缩回容纳腔31a。
如果驱动组件70同时驱动活动支架32和摄像模组60,由于动活动支架32和摄 像模组60两者的总重量较大,因此驱动组件70需要承载较大的载荷,从而驱动组件70自身的尺寸设计较大,并且驱动活动支架32和摄像模组60移动的速度较慢。本申请实施例中,由于活动支架32和摄像模组60各自独立,因此驱动组件70用于单独驱动活动支架32移动,从而驱动组件70的载荷要求低,同时可以有利于驱动活动支架32实现快速移动,缩短活动支架32移动调整时间,缩短摄像模组60启动时间。
在一些可实现的方式中,参见图5或图6所示,第一驱动单元71包括第一电致伸缩体711。第一电致伸缩体711收缩时,第一驱动单元71对活动支架32施加沿避让孔31b的轴向X的作用力,以驱动活动支架32移动。示例性地,第一电致伸缩体711具有预定长度。第一电致伸缩体711可以沿自身的长度方向发生收缩。本申请实施例中,第一电致伸缩体711可以作为动力源,从而第一电致伸缩体711可以通过自身的收缩方式,使得第一驱动单元71的活动端在避让孔31b的轴向X上产生位移量,从而驱动活动支架32移动。需要说明的是,第一驱动单元71对活动支架32施加的作用力,也可以不完全沿避让孔31b的轴向X,只要有轴向X方向的分量使驱动活动支架32在避让空间中移动即可。下述实现方式也类似,不再赘述。
电子设备10还包括激励电路100。第一电致伸缩体711和激励电路100电连接。通过激励电路100可以控制第一电致伸缩体711。激励电路100工作时,可以对第一电致伸缩体711施加激励电信号,以使第一电致伸缩体711收缩。激励电路100关闭时,第一电致伸缩体711可以恢复至初始状态。
由于第一驱动单元71的第一电致伸缩体711可以用于产生驱动活动支架32移动的动力,而第一电致伸缩体711自身的体积可以设计的较小,因此第一驱动单元71整体的结构设计可以更加紧凑,从而第一驱动单元71整体占用较小的空间,有利于容纳腔31a释放更多的空间布置更多的结构件或者有利于电子设备10轻薄化设计。
在一些可实现的方式中,第一电致伸缩体711具有相对的两个端部。第一电致伸缩体711的一端与壳体31连接以形成固定端,另一端与活动支架32连接以形成活动端。沿避让孔31b的轴向X,固定端位于活动端靠近避让孔31b的一侧。第一电致伸缩体711通过自身收缩可以直接驱动活动支架32,从而第一电致伸缩体711和活动支架32之间可以不需要额外设置传动结构,有利于简化第一电致伸缩体711和活动支架32之间的结构设计。第一电致伸缩体711和活动支架32之间传动链较短,有利于提高第一电致伸缩体711和活动支架32之间的传动效率,也有利于减小误差累积,提高活动支架32自身的位置移动精度。
在一些示例中,第一电致伸缩体711的一端与壳体31朝向容纳腔31a的内壁连接,另一端与活动支架32位于容纳腔31a内且远离壳体31的端部连接,从而可以增大固定端和活动端之间的距离,从而可以增大第一电致伸缩体711自身的长度,有利于在有限的空间内增大第一电致伸缩体711的收缩量,以增大活动支架32的位移量。壳体31的内壁为朝向容纳腔31a的表面。
在一些示例中,参见图6所示,壳体31面向容纳腔31a的内壁设置有连接件31c。活动支架32具有连接凸台32a。连接凸台32a位于活动支架32的外侧。第一电致伸缩体711的一端与连接件31c相连,另一端与连接凸台32a相连。示例性地,第一电致伸缩体711位于活动支架32的外侧。
在一些示例中,两组以上的第一驱动单元71沿避让孔31b的周向间隔设置。两组以上的第一驱动单元71可以共同对活动支架32施加驱动力,从而一方面,每组第一驱动单元71的载荷量要求可以降低;另一方面,两组以上的第一驱动单元71可以在不同的位置对活动支架32施加驱动力,有利于提高活动支架32的受力稳定性,降低活动支架32受力失衡而相对避让孔31b的轴线S发生倾斜的可能性。示例性地,第一驱动单元71的数量可以但不限于是两组、三组或四组。
在一些示例中,两组以上的第一驱动单元71沿避让孔31b的周向均匀分布。
在一些示例中,第一电致伸缩体711可以沿避让孔31b的轴向X延伸。第一电致伸缩体711的两端可以沿避让孔31b的轴向X对应设置。第一电致伸缩体711与壳体31相连的端部位于第一电致伸缩体711与活动支架32相连的端部的上方。示例性地,每组第一驱动单元71可以包括至少一个第一电致伸缩体711。
在一些示例中,参见图6所示,每组第一驱动单元71包括两个相交设置的第一电致伸缩体711。示例性地,两个第一电致伸缩体711在第一平面上的投影相交或投影的延长线相交。需要说明的是,第一平面为垂直于避让孔31b的轴向X的平面。或者,示例性地,两个第一电致伸缩体711在第一平面上的投影或投影的延长线之间的夹角可以为0°。
每个第一电致伸缩体711与避让孔31b的轴线S相交,从而第一电致伸缩体711的收缩方向与避让孔31b的轴向X相交。第一电致伸缩体711的收缩时,第一电致伸缩体711与活动支架32相连的端部可以在避让孔31b的轴向X上产生位移分量。两个相交设置的第一电致伸缩体711同时对活动支架32施加驱动力,有利于保证活动支架32受力平衡,提高移动过程的稳定性。示例性地,两个第一电致伸缩体711相对避让孔31b的轴线S对称设置。示例性地,两个第一电致伸缩体711各自与壳体31相连的端部之间的间距大于各自与活动支架32相连的端部之间的间距。
本申请实施例中,第一电致伸缩体711与避让孔31b的轴线S相交设置的方式,可以增大固定端和活动端之间的距离,从而可以增大第一电致伸缩体711自身的长度,有利于在有限的空间内增大第一电致伸缩体711的收缩量,以增大活动支架32的位移量。
在一些示例中,图7示意性地显示了一实施例的电子设备10的局部剖视结构。参见图7所示,第一电致伸缩体711的两端分别与壳体31相连。第一电致伸缩体711的中间区域与活动支架32相连。第一电致伸缩体711的两端位于第一电致伸缩体711的中间区域的同一侧,使得第一电致伸缩体711整体呈折弯结构。相对第一电致伸缩体711的中间区域,第一电致伸缩体711的两端靠近活动支架32设置。示例性地,壳体31包括转接部31e。转接部31e位于活动支架32靠近摄像模组60的一侧。第一电致伸缩体711的两端分别与转接部31e相连。示例性地,每组第一驱动单元71可以包括一个第一电致伸缩体711。
示例性地,图8示意性地显示了一实施例的电子设备10的局部结构示意图。参见图7和图8所示,壳体组件30还包括转接件34。转接件34可以设置于活动支架32面向摄像模组的一侧。转接件34连接活动支架32和驱动组件70。驱动组件70通过转接件34向活动支架32施加沿避让孔31b的轴向X的作用力,以驱动转接件34和 活动支架32移动。第一电致伸缩体711的中间区域位于转接件34远离活动支架32的一侧。第一电致伸缩体711的中间区域与转接件34可移动连接。第一电致伸缩体711位于转接件34两侧的两段之间具有预定夹角。第一电致伸缩体711整体收缩时,可以驱动转接件34和活动支架移动。
示例性地,转接件34位于壳体31的转接部31e面向活动支架32的一侧。沿避让孔31b的轴向,转接件34与壳体31的转接部31e之间具有间隙。
在一些示例中,图9示意性地显示了一实施例的电子设备10的局部分解结构。参见图9和图10所示,沿避让孔31b的轴向X,转接件34可移动连接于活动支架32。壳体组件还包括缓冲件35。缓冲件35设置于活动支架32和转接件34之间并产生在避让孔31b的轴向X上的抵持力。在活动支架32处于伸出状态时,如果活动支架32受到外力作用,例如电子设备10发生跌落而活动支架32接触底面的情况,活动支架32会相对转接件34向缩回方向移动预定距离,此时,缓冲件35可以对活动支架32施加反向作用力,以起到缓冲作用,有利于降低活动支架32自身因受到外部冲击而发生损坏的可能性,或者,有利于降低因活动支架32的冲击力直接传递至驱动组件70而导致驱动组件70发生结构损坏的可能性。在冲击力消失后,缓冲件35可以推动活动支架32回复到伸出位置。示例性地,缓冲件35处于活动支架32和转接件34挤压状态,或者,缓冲件35处于原始长度状态。示例性地,缓冲件35的一端与活动支架32相连,另一端与转接件34相连。示例性地,参见图10所示,转接件34具有容纳空间341。缓冲件35设置于容纳空间341内。示例性地,转接件34可以为柱状结构。缓冲件35可以是弹簧。
在一些可实现的方式中,图11示意性地显示了本申请一实施例的电子设备10的局部分解结构。图12示意性地显示了本申请一实施例的包括处于缩回位置的活动支架32的电子设备10的局部剖视结构。参见图11和图12所示,第一驱动单元71还包括第一致动件712。第一致动件712具有预定长度。第一致动件712的长度方向可以与避让孔31b的轴线S相交设置。第一致动件712的两端可以相对壳体31具有活动自由度。在一些示例中,第一致动件712的端部与壳体31可以滑动连接。示例性地,活动支架32与第一致动件712的中间区域连接。
第一电致伸缩体711与避让孔31b的轴向X相交,从而第一电致伸缩体711的收缩方向与避让孔31b的轴向X相交。第一电致伸缩体711的两端分别可以与第一致动件712的两端相连。在一些示例中,第一电致伸缩体711的端部可以与第一致动件712的端部焊接、粘接或者铆接。或者,第一致动件712的端部可以夹持第一电致伸缩体711的端部。
图13示意性地显示了本申请一实施例的包括处于伸出位置的活动支架32的电子设备10的局部剖视结构。参见图13所示,第一电致伸缩体711收缩后,第一电致伸缩体711可以带动第一致动件712的两端相互靠近,使得与活动支架32相连的第一致动件712沿避让孔31b的轴向X隆起,以驱动活动支架32移动。第一致动件712的中间区域隆起程度相对较大,从而可以驱动活动支架32产生较大的位移量。
在一些示例中,第一电致伸缩体711的收缩方向与避让孔31b的轴向X相互垂直。
在一些示例中,参见图12和图13所示,沿避让孔31b的轴向X,第一电致伸缩 体711的两侧分别设置第一致动件712。第一电致伸缩体711收缩时,第一电致伸缩体711可以同时带动两侧的第一致动件712发生隆起。本申请实施例中,第一电致伸缩体711的收缩量可以通过两侧的第一致动件712进行放大,使得活动支架32的位移量大于第一电致伸缩体711的收缩量,有利于使用长度较短的第一电致伸缩体711即可驱动活动支架32获得较大的位移量。在一些示例中,两侧的第一致动件712之间可以设置两个以上的第一电致伸缩体711,从而有利于提高第一驱动单元71的承载能力,降低因载荷偏大而导致第一电致伸缩体711发生断裂的可能性。
在一些示例中,参见图12所示,第一致动件712朝远离第一电致伸缩体711的方向凸起。壳体31包括第一限位部31d。沿避让孔31b的轴向X,第一驱动单元71可以位于活动支架32和第一限位部31d之间。远离活动支架32的第一致动件712连接于第一限位部31d,从而第一限位部31d可以对远离活动支架32的第一致动件712起到限位约束的作用。活动支架32与靠近活动支架32的第一致动件712相连。本申请实施例中,在第一电致伸缩体711收缩时,两侧的第一致动件712各自朝远离第一电致伸缩体711的方向隆起,从而活动支架32的位移量可以等于两侧的第一致动件712各自的隆起量之和。
在一些示例中,图14示意性地显示了本申请一实施例的电子设备10的局部剖视结构。参见图14所示,第一致动件712朝靠近第一电致伸缩体711的方向凸起。壳体31包括第一限位部31d。靠近活动支架32的第一致动件712连接于第一限位部31d,从而第一限位部31d可以对靠近活动支架32的第一致动件712起到约束限位的作用。活动支架32与远离活动支架32的第一致动件712相连。本申请实施例中,在第一电致伸缩体711收缩时,两侧的第一致动件712各自朝靠近第一电致伸缩体711的方向隆起,从而活动支架32的位移量可以等于两侧的第一致动件712各自的隆起量之和。

示例性地,驱动器83可以是电动机。锁止体84可以是销轴。活动支架32具有锁止孔。锁止体84可滑动地连接于壳体31。电动机的输出轴可以与锁止体84螺纹连接。电动机通过正转或反转驱动锁止体84移动,以伸入或退出锁止孔。
示例性地,驱动器83可以是电磁铁。锁止体84可以是伸缩杆。活动支架32具有与锁止体84相配合的锁止孔。电磁铁套设于锁止体84的外部。电磁铁正向通电时,可以带动锁止体84退出锁止孔,以解锁活动支架32。电磁铁反向通电时,可以带动锁止体84伸入锁止孔,以锁止活动支架32。
在一些可实现的方式中,第一驱动单元71包括第一电致伸缩体711。通过第一电 致伸缩体711收缩产生的驱动力驱动活动支架32伸出。在活动支架32伸出至预定位置时,锁止组件80将活动支架32锁止于当前位置,此时,可以对第一电致伸缩体711进行断电操作,从而不需要对第一电致伸缩体711持续通电,有利于降低电子设备10的能耗,节约电能。
在一些可实现的方式中,第二驱动单元72包括第二电致伸缩体721。通过第二电致伸缩体721收缩产生的驱动力驱动活动支架32缩回。在活动支架32缩回至预定位置时,锁止组件80将活动支架32锁止于当前位置,此时,可以对第二电致伸缩体721进行断电操作,从而不需要对第二电致伸缩体721持续通电,有利于降低电子设备10的能耗,节约电能。
在一些可实现的方式中,参见图29所示,电子设备10还包括位置传感器90。位置传感器90用于检测活动支架32的位置。位置传感器90检测到活动支架32移动至预定位置时,可以将活动支架32的位置信息上传至控制器。电子设备10包括锁止组件80时,控制器可以控制锁止组件80将活动支架32锁止于当前位置,从而活动支架32可以精准地保持在任意位置。
在一些可实现的方式中,参见图29所示,壳体31包括第一导向件31g。活动支架32包括第二导向件323。第一导向件31g和第二导向件323可移动连接。在活动支架32伸出或缩回运动时,第一导向件31g和第二导向件323共同用于对活动支架32导向,以保证活动支架32运动过程平稳。在一些示例中,第一导向件31g和第二导向件323相互套设,以实现滑动配合。
在一些可实现的方式中,图30为本申请一实施例提供的包括锁止单元110的电子设备10的局部剖视结构。参见图30所示,电子设备10还包括锁止单元110。锁止单元110用于锁止转接件34,以使转接件34和活动支架32保持于当前位置。锁止单元110可以通过锁止转接件34实现对活动支架32进行锁止,保证活动支架32的位置稳定性,不易发生意外移动。
在一些示例中,锁止单元110可以包括驱动机构111和锁止销112。驱动机构111可以驱动锁止销112移动,以锁止或解锁转接件34。示例性地,驱动机构111可以包括电致伸缩部件1111和弹性部件1112。需要解锁转接件34时,电致伸缩部件1111通电收缩以带动锁止销112远离转接件34移动,同时压缩弹性部件1112。需要再次锁止转接件34时,电致伸缩部件1111断电,而弹性部件1112释放弹性势能,以推动锁止销112靠近转接件34移动。示例性地,电致伸缩部件1111可以但不限于是形状记忆合金体或压电伸缩体。弹性部件1112可以但不限于是弹簧。
