Description

摄像头组件及电子设备
本申请要求于2022年04月19日提交中国专利局、申请号为202220911967.5、发明名称为“摄像头组件及电子设备”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
本申请涉及终端设备技术领域，尤其涉及一种摄像头组件及电子设备。
背景技术
随着终端技术的进步，电子设备配置多个摄像头成为发展趋势，同时，随着对摄像头组件性能要求的提高，可伸缩的摄像头成为一种设计趋势。
现有技术中，摄像头的可伸缩方案多是针对单个摄像头，即给一个摄像头配置一套伸缩机构，对于多摄像头组件来说，若仍采用一个摄像头一套伸缩机构的方案，则多个摄像头的多套伸缩机构占据主板的大部分面积，不仅影响整机的结构布局，也影响整机功耗。
发明内容
本申请提供了一种摄像头组件及电子设备，通过结构优化可以使两个以上的摄像模组共用一套驱动机构，有利于减小摄像头组件的占用空间和降低整机功耗。
第一方面，本申请提供了一种用于电子设备的摄像头组件，包括载台、基座和驱动部件，其中，载台上设置有镜片，该镜片与至少两个摄像模组匹配；基座与载台通过第一滑动副连接；驱动部件用于驱动载台带动镜片相对基座内缩或外伸。这里将靠近基座方向的动作称之为内缩，远离基座方向的动作称之外伸，换言之，载台可带动镜片相对基座伸缩。
通过上述结构设置，该摄像头组件将与至少两个摄像模组匹配的镜片通过驱动部件驱动进行伸缩，避免了单个摄像模组需要配置一套驱动机构的情形，镜片的一次伸缩就可兼容不同摄像模组的拍摄需求，多个摄像模组只配置一套驱动机构得以实现，从而减小了摄像头组件的占用空间，也降低了整机功耗；同时，该结构设计有利于降低摄像头组件的整体高度，避免摄像头组件相对电子设备的壳体的凸出量较大而影响用户体验。
在一种可能的实现方式中，载台和基座之间形成有容纳驱动部件和摄像模组的容纳腔室。如此设置，有利于进一步减小摄像头组件的占用空间。
在另一种可能的实现方式中，载台和基座之间设有伸缩台，伸缩台与载台相对固定，驱动部件通过驱动伸缩台带动载台伸缩。如此，方便布局和提高结构可靠性。
示例性的，载台和伸缩台之间为面接触的固定方式，以确保载台伸缩的稳定性。

在另一种可能的实现方式中，传动机构还包括齿轮组件，致动部件通过齿轮组件驱动丝杆转动，换言之，齿轮组件将致动部件输出的动力传递至丝杆。如此，有利于相关结构部件的灵活布局。

在另一种可能的实现方式中，第一支座上设有导向柱，丝母可滑动地套设于导向柱。如此，可较为精确地控制丝母的运动轨迹，提高载台伸缩动作的可靠性。
在另一种可能的实现方式中，驱动部件还包括与第一支座相对固定的第二支座，伸缩台与第二支座通过第二滑动副连接。如此，有利于精确控制伸缩台的运动轨迹，避免伸缩台动作过程中的卡顿、卡死或不平稳等不良现象，从而确保载台动作的精确性可靠性。
示例性的，伸缩台和第二支座之间的第二滑动副包括沿伸缩台的伸缩方向滑动配合的滑槽和滑板，一者设于伸缩台，一者设于第二支座，即，可以将滑槽设置在伸缩台上，滑板设置在第二支座上，也可以反向设置，将滑槽设置在第二支座上，将滑板设置在伸缩台上，实际应用中可根据设置方便性进行选择。
在另一种可能的实现方式中，伸缩台和第二支座之间设有使伸缩台保持在外伸工作位的限位结构，换言之，该限位结构能够限制处于外伸工作位的伸缩台和第二支座之间的相对位置。如此，在使用摄像头组件需要镜片处于外伸状态时，限位结构的设置可确保伸缩台始终处于外伸状态，确保摄像头组件的正常工作。
示例性的，限位结构包括电磁部件和磁性件，通电后的电磁部件与磁性件之间具有磁吸力；电磁部件和磁性件中的一者设于伸缩台，另一者设于第二支座。
实际应用中，可将电磁部件设于非动作件即第二支座上，将磁性件设于伸缩台上，方便对电磁部件通断电的控制件进行布置；应用时，在伸缩台向外伸出至外伸工作位后，可控制电磁部件通电以与磁性件吸合，需要伸缩台内缩时，控制电磁部件断电，方便伸缩台的缩回动作。
在另一种可能的实现方式中，载台和基座之间的第一滑动副包括至少两组滑动配合的滑道和滑块，滑道和滑块中的一者设于载台，另一者设于基座。如此，设置至少两组滑动配合的滑道和滑块，有利于载台相对基座伸缩动作的精确控制，避免载台在伸缩动作过程中偏斜，从而保证摄像头组件的工作性能。
在一种可能的实现方式中，载台和基座之间具有第一限位副，第一限位副用于限制载台和基座在外伸工作位的相对位置。如此，可避免载台外伸过渡而导致的卡滞等隐患。

具体实施方式
本申请实施例提供了一种摄像头组件，以及应用该摄像头组件的电子设备，针对伸缩式的摄像头组件进行了结构优化，使得多个摄像模组可共用一套驱动机构，以减小摄像头组件的占用空间和降低整机功耗。
请参考图1至图3，图1示出了摄像头组件处于内缩工作位的结构示意图，图2为图1的另一视角的结构示意图，图3示出了摄像头组件处于外伸工作位的结构示意图。
该实施例中，摄像头组件包括镜片20，镜片20与两个以上的摄像模组相匹配；镜片20设置在载台40上，载台40通过第一滑动副与基座30连接，基座30与电子设备 的壳体10相对固定，具体来说，基座30与壳体10的电池盖11固接，各摄像模组与壳体10相对固定，即摄像模组与基座30的位置相对固定。载台40在驱动部件50的驱动下能够相对基座30内缩或外伸以带动镜片20进行工作位的切换，镜片20位于图1所示的内缩工作位时，摄像头组件未被启用，镜片20处于图3所示的外伸工作位时，摄像头组件被启用。
这里需要指出的是，上述内缩或者外伸是根据载台40的动作方向而言的，载台40向靠近壳体10的方向移动称之为内缩，向远离壳体10的方向移动称之为外伸。
在其他的实施例中，基座30也可以与电子设备的壳体10的其他固定结构连接。
通过上述结构设置，本方案中将与两个以上的摄像模组匹配的镜片20通过驱动部件50的驱动进行外伸或内缩，镜片20的一次伸缩就可兼容不同摄像模组的拍摄需求，避免了单个摄像模组单独进行伸缩的情形，换言之，避免了单个摄像模组需匹配一套驱动机构的情形，本方案使得两个以上的摄像模组只需配置一套驱动机构50就能满足拍摄性能的需求，减小了摄像头组件的占用空间，不会影响电子设备其他功能模块的布局，也降低了整机功耗；同时，本方案的结构设计有利于降低摄像头组件的整体高度，避免摄像头组件相对电子设备的壳体10的凸出量较大而影响用户体验。
该实施例中，在载台40和基座30之间形成有容纳驱动部件50和摄像模组的容纳腔室，可一并参考图4理解，驱动部件40和摄像模组可设在载台40和基座30之间，为了不影响镜片20和摄像模组之间的配合工作，载台20在对应于各摄像模组的区域设有开口411，可以理解为载台20上设置开口411的区域下方对应设有摄像模组。这样，摄像头组件的集成度更高，有利于进一步减小摄像头组件的占用空间。
请参考图5，该图为载台40的结构示意图。该实施例中，载台40包括台面部41，该台面部41的顶壁面用以支撑定位镜片20；载台40还包括位于台面部41上方的第一周壁部42和位于台面部41下方的第二周壁部43，具体来说，第一周壁部42自台面部41的顶壁外周向上延伸形成，第二周壁部43自台面部41的底壁外周向向下延伸而成。
需要指出的是，这里的方位词上、下以载台40在图5中所示状态为基础定义的，下文中涉及到的方位词也均是基于相关部件在图中所处的状态或者部件相互之间的位置关系，方位词的引入旨在方便描述，不构成对保护范围的限制。
组装后，镜片20的外周被第一周壁部42包围，可限制镜片20的相对位置，避免其偏移。
请一并参考图6，该图示出了基座30的结构，基座30包括呈筒状的筒壁部31和底壁部32，底壁部32与筒壁部31相垂直，底壁部32位于筒壁部31底端的外周，可将底壁部32理解为筒壁部31的翻边结构。组装时，基座30可通过其底壁部32与电子设备的电池盖11固接，具体的，底壁部32与电池盖11朝向电子设备内部的一侧壁面粘接固定，可选用背胶粘贴的方式，简单又可靠。
载台40通过其第二周壁部43与基座30滑动连接，具体地，载台40的第二周壁部43滑动插装于基座30的筒壁部31，图示方案中，第二周壁部43内插于筒壁部31，两者之间通过第一滑动副连接。在其他实施例中，也可以是载台40可滑动地外套于基座30。
图示示例中，基座30和载台40整体上呈圆形结构，但在实际应用中，两者的外形形状不限于此，可根据具体需求来定，比如可以呈椭圆形或者长方形等其他形状结构。
请一并参考图7，本实施例中，第一滑动副包括四组滑动配合的滑道311和滑块431，具体地，滑道311形成于基座30的筒壁部31的内周壁，滑块431设于载台40的第二周壁部43的外周壁。显然，四组滑道311和滑块431平行设置，如此有利于载台40相对基座30伸缩的平稳性及动作轨迹的精确性，可避免载台40在动作过程中偏斜，从而利于确保摄像头组件的拍摄性能。
更具体地，四组滑道311和滑块431沿着基座30和载台40的周向均匀排布，以利于载台40和基座30之间滑道配合的均衡。
在其他实施例中，滑道311和滑块431的组数和排布可根据实际情况进行调整。
请一并参考图8至图10，其中，图8为图7中A-A向剖面视图，其中涉及一组滑道311和滑块431配合位置的剖视，图9和图10分别示出了该组滑道311和滑块431在内缩工作位和外伸工作位的局部放大图，以清楚显示滑道311和滑块431的配合结构。
基座30的筒壁部31的内周壁通过向外周壁所在方向凹陷形成滑道311，载台40的第二周壁部43的底部具有凸起，形成滑块431，该滑块431可相对滑道311滑动。为限制载台40和基座30在外伸工作位和内缩工作位的相对位置，避免载台40在工作位切换中滑动过渡而导致卡滞等隐患，基座30和载台40之间具有第一限位副和第二限位副，其中，第一限位副用于限制载台40和基座30在外伸工作位的相对位置，第二限位副用于限制载台40和基座30在内缩工作位的相对位置。
具体的，第一限位副包括第一止动面3111和第二止动面4311，如图9所示，第一止动面311为滑道311在基座30的筒壁部31上形成的朝下的台阶面，第二止动面4311为滑块431的上表面，第一止动面3111上设有第一磁性部件33，第二止动面4311上设有第二磁性部件44，第一磁性部件33和第二磁性部件44的磁极相反，也就是说，两者之间具有磁吸力。
处于内缩工作位，载台40的第二周壁部43基本伸入基座30的筒壁部31内，滑块431靠近基座30的底部，如图9所示；当驱动部件50驱动载台40相对基座30向外伸出时，载台40的滑块431沿滑道311向上滑动，至第二磁性部件44与第一磁性部件33相吸合的位置，如图10所示，此时，载台40处于外伸工作位，在第一磁性部件33和第二磁性部件44的磁吸力作用下，载台40可保持在该工作位，以保证摄像头组件的正常工作。
实际应用中，第一磁性部件33和第二磁性部件44均可选用永磁体，结构简单又可靠。
具体的，第二限位副包括第一限位面312和第二限位面412，第一限位面312具体为基座30的筒壁部31的顶壁面，第二限位面412具体为台面部41和第二周壁部43的连接处形成的朝下的台阶面，载台40相对基座30向下移动处于内缩工作位时，第二限位面412与第一限位面312相抵，如图9所示，以限制载台40继续向下移动。
可以理解，在图8至图10所示的视角下，载台40下移的方向为载台40相对靠近电子设备壳体10的方向，载台40上移的方向为载台40相对远离电子设备壳体10的方向。
需要指出的是，在其他实施例中，前述滑块和滑道的结构也可反向设置，即将滑道设置于载台40上，将滑块设置于基座30上，相关结构可在此基础上适应性调整，不再赘述。
再参考图4，该实施例中，在载台40和基座30之间设有伸缩台60，伸缩台60与载台40相对固定，驱动部件50通过驱动伸缩台60来带动载台40伸缩，如此，方便相关结构件的部件和提高结构可靠性。
具体来说，伸缩台60和载台40之间通过面接触的方式固定，以确保载台40伸缩的稳定性。
如图4所示，伸缩台60朝向载台40的一侧具有支撑面61；如图5和图8所示，载台40的台面部41的底壁面可与伸缩台60的支撑面61贴合固定，台面部41的底壁面和伸缩台60的支撑面61之间可通过点胶粘接的方式来固定，当然也可采用背胶粘贴或者其他固定方式。
请一并参考图11至图16，其中，图11为图7中B-B向剖面示意图，图12和图13分别示出了伸缩台处于内缩状态和外伸状态时与驱动部件配合的结构示意图，图14示出了驱动部件的结构，图15和图16分别示出了第二支座和伸缩台的结构。
该实施例中，驱动部件50包括致动部件51和传动机构，传动机构包括传动配合的丝杆53和丝母54，致动部件51用于提供丝杆53转动的驱动力，可采用电机，以方便驱动丝杆53的正向转动和反向转动，以实现载台40工作位的切换动作；具体地，丝杆53枢接于第一支座55，第一支座55与电子设备的壳体10相对固定，比如说可以与壳体10的中框结构固定连接，丝母54与丝杆53传动配合，致动部件51驱动丝杆53转动时，因丝杆53的位置相对电子设备的壳体10固定，在传动配合作用下，丝母54沿丝杆53的长度方向滑动，设置时，丝杆53的长度方向与伸缩台60的伸缩方向一致，伸缩台60与丝母54在伸缩方向上限位连接，如此，丝母54沿丝杆53滑动时可带动伸缩台60同步滑动。
该实施例中，驱动部件50的传动机构还包括齿轮组件，齿轮组件传动设置在致动部件51的动力输出端和丝杆53之间，一方面利于驱动部件50的结构布局，给整个摄像头组件的布局提供灵活度，另一方面可以通过齿轮组件的设置来调整丝杆53的转速，即齿轮组件相当于一个变速机构。在图示示例中，齿轮组件52包括第一齿轮521、第二齿轮522、第三齿轮523和第四齿轮524，第一齿轮521与致动部件51的输出端连接，第二齿轮522与第一齿轮521传动啮合，第三齿轮523与第二齿轮522传动啮合，第四齿轮524与第三齿轮523传动啮合，第四齿轮524固套于丝杆53，如此，致动部件51的驱动力可经齿轮组件52传递至丝杆53；其中，第二齿轮522和第三齿轮523均可通过齿轮轴设置在第一支座55上，避免额外再设置安装部件，也能提高驱动部件50的集成度；当然，根据实际结构设置，也可将第二齿轮522和第三齿轮523通过齿轮轴直接安装在电子设备的固定结构上。
各齿轮的结构形式可根据传动配合和布局需求来设置，齿轮组件52的齿轮数目也类似，不局限于图中所示方案。
如图12和图14所示，该实施例中，致动部件51可通过接电pin(针)一511与电子设备的主板电连接，主板上的相关控制器件在接收到需要启动摄像头组件的命令时，可通过接电pin一511输入电流来驱动致动部件51转动并能够控制其转动方向。
该实施例中，第一支座55上还设有导向柱56，前述丝母54可滑动地套设于导向柱56，通过导向柱56对丝母54的滑动进行导向，可较为精确地控制丝母54的运动轨迹，提高载台40伸缩动作的可靠性。
为确保伸缩台60伸缩动作的平稳性，驱动部件50还包括与第一支座55相对固定的第二支座57，第二支座57与电子设备的壳体10固定连接，具体也可与壳体10的中框结构连接；伸缩台60通过第二滑动副与第二支座57滑动连接，图示方案中，第二支座57和第一支座55分别设置在伸缩台60的相对侧，这样，在保证伸缩台60平稳动作的基础上，避免占用载台40和基座30之间过多的空间，以给摄像模组的布置留出足够的布置空间。
如图11所示，丝母54包括与丝杆53传动配合的本体541和自所述本体541向伸缩台60所在方向延伸的板部542，伸缩台60靠近丝母54一侧的侧壁部具有向下延伸的限位凸部62，该限位凸部62与侧壁部之间形成有朝下丝母54的阶梯面621，伸缩台60的限位凸部62插入板部542和第一支座55之间，板部542与伸缩台60的前述阶梯面621相抵，如此实现丝母54和伸缩台60在伸缩方向上的限位连接。
除了图示限位方式，还可在丝母54和伸缩台60上分别形成插接配合的槽和凸起结构，来实现两者在伸缩方向上的限位连接。当然还有其他限位的结构形式，此处不再一一列举。
伸缩台60和第二支座57之间的第二滑动副包括平行设置的两组滑动配合的滑槽571和滑板63，滑槽571设于第二支座57，滑板63设于伸缩台60，滑板63滑动地插装在滑槽571内，如此，有利于较为精确地控制伸缩台60的运动轨迹，避免伸缩台60在伸缩动作过程中出现卡顿、卡死或不平稳等不良现象。
当然，在其他实施例中，如果结构允许、设置方便，也可将滑槽设置在伸缩台60上，与滑槽滑动配合的滑板设置在第二支座57上。
该实施例中，在伸缩台60和第二支座57之间设有使伸缩台60保持在外伸工作位的限位结构，换言之，该限位结构用于限制外伸工作位下伸缩台60和第二支座57的相对位置。如此，在摄像头组件启动后，可确保伸缩台60处于外伸状态，确保摄像头组件工作性能的稳定性。
具体地，限位结构包括电磁部件58和磁性件(图中未示出)，通电后的电磁部件58与磁性件之间具有磁吸力，图示方案中，电磁部件58设于第二支座57，第二支座57相对伸缩台60来说为非动作部件，有利于电磁部件58通断电的相关结构设置，磁性件设置在伸缩台60上，具体可设置在伸缩台60的滑板63上；具体地，第二支座57上还设有接电pin(针)二581，用于电连接电磁部件58和电子设备的主板，通过主板上的相关控制器件来控制电磁部件58的通电或断电。具体来说，在伸缩台60向外 伸出至外伸工作位时，控制电磁部件58通电，以产生与磁性件吸合的磁力，当不使用摄像头组件，需要将伸缩台60缩回时，可控制电磁部件58断电，避免其与磁性件之间的磁吸力影响伸缩台60的内缩动作。
结合前述载台40和基座30的配合关系说明可知，驱动部件50驱动伸缩台60带动载台40处于外伸工作位时，载台40和基座30之间通过第一磁性部件33和第二磁性部件44吸合以保持位置，伸缩台60和第二支座57之间通过通电的电磁部件58和磁性件吸合保持位置。可以理解，在相关结构可靠性足够的情况下，在其他实施例中，也可以不设置第一磁性部件33和第二磁性部件44，或者不设置电磁部件58和磁性件。
除了前述摄像头组件，本申请实施例还提供了一种电子设备，该电子设备包括如前述图1至图16所述的摄像头组件。该电子设备可以为手机、平板电脑或其他具备摄像功能的终端产品；其中，手机的形式包括但不限于折叠机和直板机等。
电子设备的壳体10具有用于组装摄像头组件的开孔111，方便摄像头组件的载台40带动镜片20相对壳体10伸缩动作。
在具体实现中，摄像头组件的非动作部件可以直接与壳体10的相关部件或者电子设备的其他部件连接，也可以通过中间过渡的附座等形式与壳体10连接。
该电子设备的气体功能构成非本申请的核心发明点，本文不再赘述。
