技术领域
本公开涉及通信设备技术领域，特别是涉及一种摄像装置以及移动终端。
背景技术
随着电子技术的发展，智能移动终端成为生活中必不可少的电子设备，而拍摄功能是移动终端中必不可少的功能之一。目前移动终端通常在正面显示屏一侧设有前置摄像头，用于实现自拍等功能。但前置摄像头需要透过触摸屏的透明玻璃进行拍摄，因此在移动终端正面显示屏一侧，通常需要预留一定的区域布置前置摄像头，这样就影响了显示屏在长度方向尺寸上的扩展，降低了移动终端的屏占比和移动终端的视觉体验。
发明内容
本公开实施例提供一种摄像装置，以解决移动终端的屏占比低和移动终端的视觉体验差的问题。
为了解决上述技术问题，本公开是这样实现的：
第一方面，本公开实施例提出了一种摄像装置，应用于移动终端，包括：
导轨；摄像组件，包括按压部件以及设置于按压部件的摄像单元，按压部件可移动地连接于导轨，通过对按压部件施加沿导轨延伸方向的按压力，按压部件沿导轨作直线往复运动，以带动摄像单元在伸出位置和缩回位置切换；锁止部件，与按压部件相连接，以锁止或释放按压部件，锁止部件在摄像单元处于伸出位置或缩回位置时锁止按压部件，在摄像单元处于伸出位置或缩回位置，并且按压部件受到按压力作用时，锁止部件释放按压部件；弹性部件，与按压部件相连接，在锁止部件释放按压部件时，对按压部件提供 沿导轨延伸方向的驱动力，以使摄像单元从缩回位置切换至伸出位置。
在本公开实施例中，摄像装置通过对摄像组件施加外部按压力，并在导轨、锁止部件和弹性部件协同作用下，得以实现摄像单元的伸出或缩回，因此本实施例的摄像装置不需要额外配备驱动机构(例如，电机和传动机构)，整体结构紧凑，占用安装空间小。在本实施例的摄像装置用于移动终端时，可以作为前置摄像，从而不会与显示屏形成干涉，有利于提高显示屏尺寸和屏占比，实现全面屏，提升移动终端的视觉体验。同时，本实施例的摄像装置结构紧凑，对移动终端内部空间占用率低，从而节省安装空间，优化内部零部件布局设计。
第二方面，根据本公开实施例提供一种移动终端，包括：
支承框，具有侧板和底板以及由侧板和底板形成的容纳空间，侧板设置有与容纳空间相连通的开孔；显示屏，与支承框相连接，并覆盖容纳空间；如上述实施例的摄像装置，摄像装置设置于显示屏和底板之间，并且导轨与底板连接固定，按压部件与开孔相对应设置，按压部件受到按压力作用时，沿导轨作直线往复运动，并带动摄像单元从开孔伸出或缩回，以在伸出位置和缩回位置之间切换。
在本公开实施例中，由于移动终端所包括的摄像装置通过对摄像组件施加外部按压力，并在导轨、锁止部件和弹性部件协同作用下，得以实现摄像单元的伸出或缩回，因此本实施例的摄像装置不需要额外配备驱动机构(例如，电机和传动机构)，整体结构紧凑，从而占用移动终端内部安装空间小节省安装空间，有利于优化移动终端内部零部件布局设计。本实施例的摄像装置可以作为前置摄像，从而不会与显示屏形成干涉，有利于提高显示屏尺寸和屏占比，实现全面屏，提升移动终端的视觉体验。

在本公开的描述中，还需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可视具体情况理解上述术语在本公开中的具体含义。
为了更好地理解本公开，下面结合图1至图13对本公开实施例的摄像装置10以及移动终端进行详细描述。
图1和图2示意性地显示了本公开一实施例的摄像装置10的结构。参见图1和图2所示，本公开实施例提供的一种摄像装置10。本实施例的摄像装置10包括导轨20、摄像组件30、锁止部件40和弹性部件50。该摄像装置10可以应用于移动终端中，例如，手机、摄像机或平板电脑等等。本实施例 对移动终端的具体类型不作限定。
本实施例的导轨20用于引导摄像组件30沿预定轨迹做直线往复移动，保证摄像组件30移动过程稳定性和移动位置的精准度，降低摄像组件30移动过程发生晃动或振动的可能性。在本公开实施例中，导轨20可以由耐磨、摩擦系数小以及自润滑性能好的材料加工制造。例如，可以采用塑料或树脂等材料加工制造，但本实施例对制作导轨20所采用的具体材料不作限定。
本实施例的摄像组件30包括按压部件31以及设置于按压部件31的摄像单元32。按压部件31可移动地连接于导轨20。通过对按压部件31施加沿导轨20的延伸方向X的按压力F，使按压部件31沿导轨20作直线往复运动，以带动摄像单元32在伸出位置和缩回位置切换，其中，图1中的摄像单元32处于缩回位置，而图2中的摄像单元32处于伸出位置。该按压力F可以是用户通过肢体(例如手指)施加于按压部件31上的应力，也可以是使用外部的相关设备施加于按压部件31上的应力。摄像单元32处于伸出位置时，摄像单元32用于对物体进行拍照。摄像单元32处于缩回位置时，摄像单元32处于待机状态，不用于对物体进行拍照。
本实施例的锁止部件40与按压部件31相连接，以锁止或释放按压部件31。锁止部件40在摄像单元32处于伸出位置或缩回位置时锁止按压部件31。在摄像单元32处于伸出位置或缩回位置，并且按压部件31受到按压力F作用时，锁止部件40释放按压部件31。在按压部件31被锁止部件40锁止时，按压部件31保持当前位置不动，从而使得摄像单元32稳定保持于伸出位置或缩回位置，降低摄像单元32因按压部件31发生位置变化而无法保持于伸出位置或缩回位置的可能性。本实施例的锁止部件40和按压部件31联动，按压部件31受到按压力F作用力时，锁止部件40即被触发以释放按压部件31。
本实施例的弹性部件50与按压部件31相连接。在锁止部件40释放按压部件31的同时，弹性部件50对按压部件31提供沿导轨20延伸方向X的驱动力，以使摄像单元32从缩回位置切换至伸出位置。
参见图1所示，按压部件31上设置的摄像单元32处于缩回位置，而锁止部件40锁止按压部件31。在对按压部件31施加按压力F并撤去按压力F 后，锁止部件40释放按压部件31，从而弹性部件50推动按压部件31沿导轨20移动，直至摄像单元32抵达伸出位置。参见2所示，在摄像单元32抵达伸出位置后，锁止部件40重新锁止按压部件31，使得摄像单元32保持于该伸出位置。同理，在对图2中处于伸出状态的按压部件31施加按压力F时，锁止部件40重新释放按压部件31。持续施加按压力F，按压部件31沿导轨20移动，直至按压部件31上设置的摄像单元32抵达缩回位置。参见1所示，在摄像单元32抵达缩回位置后，锁止部件40重新锁止按压部件31，使得摄像单元32保持于缩回位置。通过上述操作按压按压部件31，即可完成一次摄像单元32的伸出和缩回操作。
本公开实施例的摄像装置10通过对摄像组件30施加外部按压力F，并在导轨20、锁止部件40和弹性部件50协同作用下，得以实现摄像单元32的伸出或缩回，因此本实施例的摄像装置10不需要额外配备驱动机构(例如，电机和传动机构)，整体结构简单、紧凑，占用安装空间小。在本实施例的摄像装置10应用于移动终端时，可以作为前置摄像，从而不会与显示屏形成干涉，有利于提高显示屏尺寸和屏占比，实现全面屏，提升移动终端的视觉体验。同时，本实施例的摄像装置10结构简单、紧凑，对移动终端内部空间占用率低，从而节省移动终端内部的安装空间，优化移动终端内部零部件布局设计。
参见图1和图3所示，本实施例的导轨20具有第一导向部21，而滑动座33与第一导向部21滑动配合。本实施例的按压部件31包括滑动座33以及与滑动座33相连接的支承件34。摄像单元32设置于支承件34。支承件34背向滑动座33的表面承载按压力F。在支承件34上单独安装固定好摄像单元32后，再将支承件34与滑动座33组装形成按压部件31，这样，便于摄像单元32安装固定，同时使得按压部件31加工制造难度低。在一个实施例中，导轨20的第一导向部21为直槽，而滑动座33上设置有与该直槽形状相匹配的凸条，从而滑动座33通过凸条与直槽滑动配合。在另一个实施例中，导轨20的第一导向部21为沿直线延伸的凸条，而滑动座33上设置有与该凸条形状相匹配的直槽，从而滑动座33通过直槽与凸条滑动配合。可选地，直槽可以是截面呈U形的U形槽或者截面呈燕尾形的燕尾槽。本实施例的滑动 座33和第一导向部21滑动配合的方式，有利于降低按压部件31和导轨20之间的摩擦阻力，也有利于提高按压部件31移动精度和移动稳定性。
本实施例的导轨20还具有第二导向部22，而支承件34与第二导向部22滑动配合。在一个实施例中，导轨20的第二导向部22为直槽，而支承件34上设置有与该直槽形状相匹配的凸条，从而支承件34通过凸条与直槽滑动配合。在另一个实施例中，导轨20的第二导向部22为沿直线延伸的凸条，而支承件34上设置有与该凸条形状相匹配的直槽，从而支承件34通过直槽与凸条滑动配合。可选地，直槽可以是截面呈U形的U形槽或者截面呈燕尾形的燕尾槽。这样，按压部件31所包括的滑动座33和支承件34各自独立地与导轨20的第一导向部21和第二导向部22滑动配合，从而导轨20对按压部件31形成双重限位，进一步提高按压部件31整体的移动精度和移动稳定性，保证摄像单元32的位置稳定性。
参见图4和图5所示，本实施例的支承件34包括具有容纳腔340a的容纳部340以及从容纳部340的同一侧延伸出的两个支脚341。两个支脚341沿与导轨20的延伸方向X相垂直的方向间隔设置。容纳部340背向滑动座33的表面承载按压力F。本实施例的支承件34的结构设计，一方面，在自身结构强度满足要求的前提下使自身结构更加轻量化；另一方面，两个支脚341之间的空间可以形成让位，以降低空间占用率。本实施例的支脚341的数量并不局限于两个，也可以是至少三个。至少三个支脚341沿与导轨20的延伸方向X相垂直的方向间隔设置。在一个实施例中，滑动座33具有朝向导轨20凸出的凸起330。支脚341至少部分地伸入滑动座33和导轨20之间且具有与凸起330卡接的卡槽341a。支脚341通过卡槽341a与凸起330卡接连接。支承件34通过支脚341与滑动座33卡接连接，从而支承件34与滑动座33连接时不需要使用额外的紧固件，保证支承件34和滑动座33结构紧凑，连接快速便捷。摄像单元32收纳于容纳腔340a，从而降低摄像单元32空间占用率，进一步提升摄像装置10整体的紧凑性，同时容纳部340对摄像单元32形成防护，降低摄像单元32在移动过程中或处于伸出位置和缩回位置时与外部物体发生刮擦或碰撞的可能性。本实施例中，支承件34通过支脚341与导轨20的第二导向部22滑动配合。
本实施例的支承件34还包括限位凸缘342。限位凸缘342设置于容纳部340的外表面上靠近支脚341的区域。限位凸缘342的延伸方向与支脚341的延伸方向相交。本实施例的限位凸缘342能够与其他外部结构件抵靠，以限制支承件34继续移动，使得摄像单元32稳定保持于伸出位置。在一个实施例中，容纳部340为扁平柱状结构，而容纳腔340a为矩形结构，限位凸缘342凸出于容纳部340的外周表面。
在一个实施例中，参见图3所示，导轨20具有让位缺口23。在摄像单元32处于缩回位置时，设有摄像单元32的容纳部340被收纳于该让位缺口23。这样，一方面，导轨20自身结构更加轻量化；另一方面，由于容纳部340被收纳于导轨20内部，因此降低容纳部340在导轨20的延伸方向X上所占用的空间，有效提升摄像装置10的整体紧凑性，降低摄像装置10整体空间占用率。
参见图6所示，本实施例的滑动座33具有第一定位部331，而导轨20具有第二定位部24。第一定位部331和第二定位部24两者沿导轨20的延伸方向X相对应设置。本实施例的弹性部件50设置于第一定位部331和第二定位部24之间。弹性部件50对滑动座33施加沿导轨20的延伸方向X的作用力，有效减小滑动座33受到沿与导轨20的延伸方向X相交方向上的分力，从而减小滑动座33在与导轨20的延伸方向X相交方向上的偏移量，进而保证按压部件31整体的移动过程更加平稳。在一个实施例中，第一定位部331和第二定位部24均为柱状结构。弹性部件50为螺旋弹簧。螺旋弹簧的轴向与导轨20的延伸方向X相同，从而对滑动座33提供沿导轨20的延伸方向X的弹性力，并且螺旋弹簧结构简单、满足轻量化要求。本实施例的弹性部件50的一端套设于第一定位部331，而另一端套设于第二定位部24，三者连接过程不需要额外的紧固件或连接件，同时组装过程快速便捷。
在一个实施例中，滑动座33朝向导轨20的表面具有容纳槽332。容纳槽332沿导轨20的延伸方向X延伸。第一定位部331和第二定位部24均与容纳槽332对应设置。弹性部件50至少部分地收纳于容纳槽332。这样，弹性部件50至少部分地被滑动座33包覆，从而一方面，弹性部件50受到滑动座33的限制约束，不易发生弯折变形；另一方面，滑动座33、弹性部件50 和导轨20三者之间结构更加紧凑，从而提升摄像装置10整体紧凑性，有效降低摄像装置10的空间占用率。
本实施例的滑动座33包括主体33a以及与主体33a相连接的两个悬臂33b。两个悬臂33b沿与导轨20的延伸方向X相垂直的方向间隔设置，以在两者之间形成缺口，从而使得滑动座33自身结构更加轻量化。在支承件34包括容纳部340和支脚341的实施例中，该缺口与各个支脚341之间形成的间隙相对应设置。悬臂33b朝靠近摄像单元32的方向延伸，而支承件34与主体33a相连接。
参见图7所示，本实施例的滑动座33背向导轨20的表面设有轨迹限位槽333。轨迹限位槽333具有缩回锁止位333a和伸出锁止位333b。锁止部件40包括连杆。连杆具有相对的两个端部以及中间部。连杆的一端与导轨20转动连接，另一端伸入轨迹限位槽333。连杆上伸入轨迹限位槽333的一端在缩回锁止位333a和伸出锁止位333b之间运动，以锁止按压部件31，从而使摄像单元32锁止于缩回位置或伸出位置。本实施例中，通过连杆和轨迹限位槽333共同协同作用实现对按压部件31锁止和释放。连杆的一端会受到轨迹限位槽333的限制约束，运动轨迹精确不变化，从而保证在摄像单元32到达缩回位置或伸出位置的同时连杆精准地处于缩回锁止位333a或伸出锁止位333b。在一个实施例中，导轨20上设置有连接孔，而连杆的端部直接插入该连接孔以与导轨20转动连接。在导轨20的延伸方向X上，缩回锁止位333a与伸出锁止位333b相互对齐设置，而连接孔与缩回锁止位333a错开设置且位于缩回锁止位333a的外侧。
在一个实施例中，参见图7和图8所示，轨迹限位槽333包括心形止回槽段334和直槽段335。参见图10所示，连杆与导轨20转动连接的一端为长臂段40a，且长臂段40a与中间部垂直。连杆伸入轨迹限位槽333的一端为短臂段40b，且短臂段40b与中间部垂直。心形止回槽段334具有沿导轨20的延伸方向X间隔的第一尖部334a和第二尖部334b。缩回锁止位333a设置于第一尖部334a。直槽段335与第二尖部334b相连通，并且沿导轨20的延伸方向X延伸。伸出锁止位333b设置于直槽段335上远离第二尖部334b的区域。连杆上的短臂段40b只能够沿心形止回槽段334单向运动(例如，沿 图示中顺时针方向或逆时针方向运动)。连杆所包括的中间部与直槽段335相交。当摄像单元32处于缩回位置时，对按压部件31施加按压力F并及时撤去按压力F，此时，按压部件31上的轨迹限位槽333会发生移动，从而连杆上的短臂段40b离开缩回锁止位333a，以释放按压部件31。连杆上的短臂段40b沿图1中虚线所示出的运动方向运动。连杆上的短臂段40b在从心形止回槽段334移出后进入直槽段335，并最终到达伸出锁止位333b，而此时摄像单元32恰好处于伸出位置并停止移动。同理，当摄像单元32处于伸出位置时，对按压部件31持续施加按压力F，此时，按压部件31上的轨迹限位槽333会发生移动，从而连杆上的短臂段40b离开伸出锁止位333b，以释放按压部件31。连杆上的短臂段40b沿图2中虚线所示出的运动方向运动。连杆上的短臂段40b在移出直槽段335后重新进入从心形止回槽段334，并最终到达缩回锁止位333a，而此时摄像单元32恰好处于缩回位置并停止移动。连杆上的短臂段40b在轨迹限位槽333内移动时，连杆上的长臂段40a在导轨20上的连接孔内转动。
在一个实施例中，参见图9所示，心形止回槽段334的底表面包括至少两个台阶面3341以及连接相邻两个台阶面3341的止回面3342。至少两个台阶面3341沿心形止回槽段334的延伸方向排布，其中一个止回面3342在第一尖部334a形成缩回锁止位333a。在连杆的端部处于缩回锁止位333a时，连杆上的短臂段40b抵靠于该止回面3342并稳定地处于锁止状态。另外，在心形止回槽段334和直槽段335的过渡区域具有止回面3342，保证连杆的端部从心形止回槽段334移动至直槽段335后不再沿相同路线从直槽段335重新回到心形止回槽段334，使得连杆的端部在轨迹限位槽333内仅能够做单向运动。直槽段335上远离第二尖部334b的区域设有与第二尖部334b沿导轨20的延伸方向X间隔设置的侧壁。侧壁形成伸出锁止位333b。在连杆的端部处于伸出锁止位333b时，连杆上的短臂段40b抵靠于该侧壁并稳定地处于锁止状态。
在一个实施例中，轨迹限位槽333和连杆的数量均为两个。两个轨迹限位槽333以及两个连杆均沿与导轨20的延伸方向X相垂直的方向间隔设置，其中，两个轨迹限位槽333对称设置，同样地，两个连杆也对称设置。这样， 滑动座33整体受力均衡，降低自身移动过程中发生振动或卡位的可能性。在滑动座33具有两个悬臂33b的实施例中，一个悬臂33b上对应设置有一个轨迹限位槽333。
参见图11所示，本公开实施例还提供一种移动终端。本实施例的移动终端包括支承框100、与支承框100层叠设置的显示屏200以及设置于支承框100和显示屏200之间的摄像装置10。本实施例的摄像装置10设置于显示屏200的下方，不会与显示屏200发生干涉。
参见图12和图13所示，本实施例的支承框100具有底板101和侧板102以及由底板101和侧板102形成的容纳空间103。侧板102设置有与容纳空间103相连通的开孔102a。本实施例的显示屏200与支承框100相连接，并覆盖容纳空间103。本实施例的摄像装置10设置于显示屏200和底板101之间，并且导轨20与底板101连接固定。按压部件31与开孔102a相对应设置。按压部件31受到按压力F作用时，沿导轨20作直线往复运动，并带动摄像单元32在伸出位置和缩回位置之间切换。摄像单元32处于伸出位置时，摄像单元32从开孔102a伸出，以执行拍照指令。摄像单元32处于缩回位置时，摄像单元32从开孔102a缩回，以停止工作并被收纳于移动终端的内部。摄像单元32从开孔102a缩回后，按压部件31与支承框100的外表面相平齐或低于支承框100的外表面，提升移动终端的外观美观度。本实施例的移动终端，用户可以通过手指从移动终端的外部对按压部件31施加按压力F，以促动摄像组件30工作，使得摄像单元32执行伸出或缩回的动作，方便可靠。本实施例的支承框100可以作为移动终端的后壳，也可以作为具有后壳的移动终端的中框，而该中框与后壳相连接。
在按压部件31包括容纳部340和限位凸缘342的实施例中，当支承件34带动摄像单元32移动至伸出位置时，限位凸缘342抵靠于侧板102的内表面，从而对支承件34形成限位，阻止支承件34继续移动。
根据本公开实施例的移动终端，由于其所包括的摄像装置10通过对摄像组件30施加外部按压力F，并在导轨20、锁止部件40和弹性部件50协同作用下，得以实现摄像单元32的伸出或缩回，因此本实施例的摄像装置10不需要额外配备驱动机构(例如，电机和传动机构)，整体结构紧凑，从而占用 移动终端内部安装空间小，能够节省安装空间，有利于优化移动终端内部零部件布局设计。本实施例的摄像装置10可以作为前置摄像，从而不会与显示屏200形成干涉，有利于提高显示屏200尺寸和屏占比，实现全面屏设计，提升移动终端的视觉体验。
虽然已经参考可选实施例对本公开进行了描述，但在不脱离本公开的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件，尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本公开并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
