Description

镜头组件、摄像模组以及电子设备
本申请要求于2022年03月17日提交中国专利局、申请号为202210265979.X、申请名称为“镜头组件、摄像模组以及电子设备”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
本申请涉及摄像技术领域，尤其涉及一种镜头组件、摄像模组以及电子设备。
背景技术
电子设备特别是手机产品，随着全面屏、指纹识别等关键技术的快速发展，电子设备的多功能设置已成为一种趋势。这种设计将较大程度地压缩摄像模组的排布空间。在这种空间排布紧张的环境下，传统手机一般采用直立式的摄像模组，以减小摄像模组在手机的长度和宽度方向上的空间占用。然而，传统的直立式摄像模组一般采用具有簧片的驱动马达。其中可以通过簧片的形变量，来提供摄像模组在调焦过程中的行程。由于簧片本身的结构约束，其形变量较小，因此驱动马达很难实现大行程的调焦，摄像模组的拍照性能较差。
发明内容
本申请提供一种大行程调焦的镜头组件、摄像模组以及电子设备。
第一方面，本申请实施例提供一种镜头组件。镜头组件包括外壳、固定座、第一镜头、第二镜头以及驱动机构。固定座滑动连接外壳，且位于外壳的内侧。
第一镜头固定连接固定座，第二镜头固定连接外壳，第二镜头位于第一镜头的像侧。
驱动机构用于使外壳与固定座相对滑动，第二镜头在镜头组件的光轴方向上，与第一镜头之间的距离增大或者减小。下文将以镜头组件的光轴方向为Z轴为例进行描述。
在本实施方式中，通过驱动外壳与固定座相对滑动，从而利用第二镜头在镜头组件的光轴方向上，与第一镜头之间的距离增大或者减小，来实现镜头组件的对焦。可以理解的是，一方面，利用第一镜头与第二镜头之间距离的增大和减小，来改变镜头组件的准焦点位置，从而有利于实现镜头组件的微距和远焦位置的拍摄，从而较大程度地提高用户体验性；另一方面，相较于通过簧片的形变来实现对焦的方案，本实施方式的外壳与固定座是通过滑动来实现连接，这样，可以避免由于簧片本身的结构约束而限制调焦行程的问题。本实施方式的外壳相对固定座滑动的距离可以更长，更有利于实现微距和远焦位置的拍摄。示例性地，外壳可以相对固定座沿Z轴方向滑动的最大距离可以为5毫米。
在一种可能的实现方式中，驱动机构用于驱动外壳在镜头组件的光轴方向上滑动。
可以理解的是，通过驱动外壳在镜头组件的光轴方向上滑动，外壳可以带动第二镜头在镜头组件的光轴方向上，远离或靠近第一镜头。由于第二镜头位于第一镜头的像侧，第二镜头不容易与第一镜头的顶部的器件发生碰撞或者干涉。
在一种可能的实现方式中，驱动机构包括磁铁和线圈，磁铁和线圈中的一者固定连接外壳，另一者固定连接固定座，磁铁与线圈相对设置。换言之，当磁铁固定连接外壳时，线圈固定连接固定座。当线圈固定连接外壳时，磁铁固定连接固定座。
可以理解的是，通过采用磁铁和线圈的驱动机构，可以避免驱动机构直接与外壳和固定座连接，从而避免驱动机构连接外壳和固定座的部分在弯折应力对镜头组件的运动精度产生影响。
可以理解的是，当驱动机构用于驱动外壳在镜头组件的光轴方向上滑动，且磁铁固定连 接外壳，线圈固定连接固定座时，磁铁为动子，线圈为定子。这样，一方面线圈不会在运动中与其他部件干涉；另一方面避免线圈在弯折应力对镜头组件的运动精度产生影响。
可以理解的是，当驱动机构用于驱动外壳在镜头组件的光轴方向上滑动，且线圈固定连接外壳，磁铁固定连接固定座时，线圈为动子，磁铁为定子。这样，由于线圈的重力较小，驱动机构的驱动力较小。
在一种可能的实现方式中，镜头组件包括导杆，外壳和固定座中的一者固定连接导杆，另一者滑动连接导杆。
可以理解的是，通过设置导杆，并将外壳和固定座中的一者固定连接导杆，另一者滑动连接导杆，从而在外壳相对固定座滑动的过程中，导杆可以起到导向的作用，从而使得外壳更加准确地沿Z轴方向滑动，也即外壳不容易发生偏移。
在一种可能的实现方式中，外壳设有间隔设置的第一凹槽和第二凹槽，固定座设有间隔设置的第三凹槽以及第四凹槽。导杆包括第一导杆以及第二导杆，第一导杆滑动连接第一凹槽的槽壁，第一导杆固定连接第三凹槽的槽壁，第二导杆滑动连接第二凹槽的槽壁，第二导杆固定连接第四凹槽的槽壁。
可以理解是，通过设置第一导杆和第一滑槽(也即第一凹槽和第三凹槽)的配合、以及第二导杆和第二滑槽(第二凹槽和第四凹槽)的配合，可以在外壳相对固定座滑动的过程中，起到导向的作用，从而使得外壳更加准确地沿Z轴方向滑动，也即外壳不容易发生偏移。
另外，通过将第一滑槽分成第一凹槽和第三凹槽设置，从而降低第一导杆与第一滑槽的装配难度。例如，可以先将第一导杆设置于第三凹槽内，再通过粘胶将第一导杆粘接于第三凹槽的槽壁，最后再将第一凹槽与第一导杆装配。
在一种可能的实现方式中，第一凹槽的槽壁呈“V”型，第二凹槽的槽壁呈弧形、“[”型或者U型，或者第一凹槽的槽壁呈弧形、“[”型或者U型，第二凹槽呈“V”型。
可以理解的是，在一种可能的实现方式中，通过设置第一凹槽的槽壁为“V”字型，使得第一凹槽的两个槽壁可以与第一导杆保持接触，第一凹槽的两个槽壁较容易夹紧第一导杆。外壳、第一导杆以及固定座连接更加稳定。此外，通过将外壳的第二凹槽设置为“[”型、圆形或者U型，从而使得第二凹槽的槽壁与第二导杆之间可以预留出一定的误差，以使第二导杆与第二凹槽不会因位置存在误差而不容易装配。
在一种可能的实现方式中，镜头组件包括第一磁吸件和第二磁吸件，第一磁吸件固定连接外壳，第二磁吸件固定连接固定座。导杆在第一磁吸件与第二磁吸件吸力下与外壳和固定座保持接触。
可以理解的是，通过将第一磁吸件固定连接外壳，第二磁吸件固定连接固定座，从而利用第一磁吸件与第二磁吸件在Y轴方向上产生的吸引力来使得外壳、第一导杆、第二导杆以及固定座紧密地保持接触。这样固定座不容易相对外壳晃动。
在一种可能的实现方式中，外壳设有第一固定槽，固定座设有第二固定槽。第一磁吸件位于第一固定槽内，第二磁吸件位于第二固定槽内。
可以理解的是，通过将第一磁吸件设置于第一固定槽内，从而一方面可以增加第一磁吸件与外壳的连接面积，从而提高第一磁吸件与外壳之间的连接牢固度，另一方面有利于镜头组件的小型化和轻型化设计。
另外，通过将第二磁吸件设置于第二固定槽内，从而一方面可以增加第二磁吸件与外壳的连接面积，从而提高第二磁吸件与外壳之间的连接牢固度，另一方面有利于进一步地实现镜头组件的小型化和轻型化设计。
在一种可能的实现方式中，导杆包括间隔设置第一导杆以及第二导杆，第一导杆和第二导杆位于固定座的同一侧。第二磁吸件位于第一导杆和第二导杆之间，或者位于第一导杆的远离第二导杆的一侧，或者位于第二导杆的远离第一导杆的一侧。
可以理解的是，第二磁吸件、第一导杆和第二导杆的排布更加紧密，这样，外壳与固定座之间的作用力更大，外壳、第一导杆、第二导杆以及固定座之间的连接更加稳定。
在一种可能的实现方式中，镜头组件包括隧道磁阻传感器以及磁栅，隧道磁阻传感器和磁栅中的一者固定连接于外壳，另一者固定于固定座，隧道磁阻传感器用于检测磁栅在不同位置的磁场强度。
可以理解的是，当外壳相对固定座沿Z轴方向移动时，外壳可以带动磁栅相对固定座沿Z轴方向移动。隧道磁阻传感器可以检测磁栅所在位置的磁场强度。这样，当隧道磁阻传感器检测到磁栅的磁场强度时，可以通过磁场强度来确定外壳的位移。可以理解的是，通过隧道磁阻传感器与磁栅的相互配合，从而实现准确地控制外壳相对固定座沿Z轴方向移动的位移，进而实现镜头组件的闭环设计。
另外，相较于通过采用霍尔传感器与磁铁的方案，在本实施方式中，通过采用隧道磁阻传感器与磁栅的配合的方案，可以准确测量位移较大的外壳。
在一种可能的实现方式中，镜头组件包括第一缓冲件，第一缓冲件固定连接固定座的底面。这样，当外壳带动第二镜头沿Z轴的正方向移动。此时，第一缓冲件可以缓冲外壳的底板与固定座之间的碰撞力，以避免外壳的底板或者固定座撞坏。
在一种可能的实现方式中，第一镜头包括镜头盖板、第一镜筒和第一镜片。第一镜片的数量为多个。至少一片第一镜片固定在镜头盖板与第一镜筒之间。其余的第一镜片固定连接第一镜筒。
在一种可能的实现方式中，第二镜头包括第二镜筒和第二镜片。第二镜片固定连接第二镜筒。
在一种可能的实现方式中，驱动机构用于驱动固定座在镜头组件的光轴方向上滑动。
第二方面，本申请实施例提供一种摄像模组。摄像模组包括模组电路板、感光芯片以及如上的镜头组件。感光芯片固定连接模组电路板，且电连接模组电路板，镜头组件的外壳连接模组电路板，第二镜头位于感光芯片的物侧。
可以理解的是，一方面，利用第一镜头与第二镜头之间距离的增大和减小，来改变镜头组件的准焦点位置，从而有利于实现摄像模组的微距和远焦位置的拍摄，从而较大程度地提高用户体验性；另一方面，相较于通过簧片的形变来实现对焦的方案，本实施方式的外壳与固定座是通过滑动来实现连接，这样，可以避免由于簧片本身的结构约束而限制调焦行程的问题。本实施方式的外壳相对固定座滑动的距离可以更长，更有利于摄像模组实现微距和远焦位置的拍摄。示例性地，外壳可以相对固定座沿Z轴方向滑动的最大距离可以为5毫米。
在一种可能的实现方式中，摄像模组包括底座，底座固定连接模组电路板，镜头组件的外壳滑动连接底座。镜头组件包括第二缓冲件，第二缓冲件固定连接外壳的底部。
这样，当镜头组件的外壳相对底座滑动时，第二缓冲件可以缓冲外壳的底板与底座之间的碰撞力，以避免外壳的底板或者底撞坏。
第三方面，本申请实施例提供一种电子设备。电子设备包括壳体以及摄像模组，模组电路板包括模组电路板、感光芯片以及镜头组件，模组电路板连接壳体，感光芯片固定连接模组电路板，且电连接模组电路板。

驱动机构用于使外壳与固定座相对滑动，第二镜头在镜头组件的光轴方向上，与第一镜头之间的距离增大或者减小。
可以理解的是，一方面，利用第一镜头与第二镜头之间距离的增大和减小，来改变镜头组件的准焦点位置，从而有利于实现电子设备的微距和远焦位置的拍摄，从而较大程度地提高用户体验性；另一方面，相较于通过簧片的形变来实现对焦的方案，本实施方式的外壳与固定座是通过滑动来实现连接，这样，可以避免由于簧片本身的结构约束而限制调焦行程的问题。本实施方式的外壳相对固定座滑动的距离可以更长，更有利于电子设备实现微距和远焦位置的拍摄。示例性地，外壳可以相对固定座沿Z轴方向滑动的最大距离可以为5毫米。
在一种可能的实现方式中，壳体包括后盖。电子设备包括摄像头装饰件以及驱动装置，摄像头装饰件滑动连接后盖；第一镜头固定连接摄像头装饰件。驱动装置用于驱动摄像头装饰件带动镜头组件，沿摄像模组的光轴方向移动。
可以理解的是，通过驱动装置驱动摄像头装饰件带动镜头组件，沿摄像模组的光轴方向移动，从而较大程度地增大镜头组件的底部空间的大小。这样，当驱动机构用于驱动外壳在镜头组件的光轴方向上滑动时，镜头组件的底部空间能够较大程度地容纳镜头组件的移动。
在一种可能的实现方式中，壳体包括后盖；电子设备包括摄像头装饰件，摄像头装饰件固定连接后盖；第一镜头固定连接摄像头装饰件。
在一种可能的实现方式中，驱动机构用于驱动外壳在镜头组件的光轴方向上滑动。
可以理解的是，通过驱动外壳在镜头组件的光轴方向上滑动，外壳可以带动第二镜头在镜头组件的光轴方向上，远离或靠近第一镜头。由于第二镜头位于第一镜头的像侧，第二镜头不容易与后盖发生碰撞或者干涉。
在一种可能的实现方式中，驱动机构包括磁铁和线圈，磁铁和线圈中的一者固定连接外壳，另一者固定连接固定座，磁铁与线圈相对设置。
可以理解的是，通过采用磁铁和线圈的驱动机构，可以避免驱动机构直接与外壳和固定座连接，从而避免驱动机构连接外壳和固定座的部分在弯折应力对镜头组件的运动精度产生影响。
可以理解的是，当驱动机构用于驱动外壳在镜头组件的光轴方向上滑动，且磁铁固定连接外壳，线圈固定连接固定座时，磁铁为动子，线圈为定子。这样，一方面线圈不会在运动中与其他部件干涉；另一方面避免线圈在弯折应力对镜头组件的运动精度产生影响。
可以理解的是，当驱动机构用于驱动外壳在镜头组件的光轴方向上滑动，且线圈固定连接外壳，磁铁固定连接固定座时，线圈为动子，磁铁为定子。这样，由于线圈的重力较小，驱动机构的驱动力较小。
在一种可能的实现方式中，镜头组件包括导杆，外壳和固定座中的一者固定连接导杆，另一者滑动连接导杆。
可以理解的是，通过设置导杆，并将外壳和固定座中的一者固定连接导杆，另一者滑动连接导杆，从而在外壳相对固定座滑动的过程中，导杆可以起到导向的作用，从而使得外壳更加准确地沿Z轴方向滑动，也即外壳不容易发生偏移。
在一种可能的实现方式中，外壳设有间隔设置的第一凹槽和第二凹槽，固定座设有间隔设置的第三凹槽以及第四凹槽。导杆包括第一导杆以及第二导杆，第一导杆滑动连接第一凹 槽的槽壁，第一导杆固定连接第三凹槽的槽壁，第二导杆滑动连接第二凹槽的槽壁，第二导杆固定连接第四凹槽的槽壁。
可以理解是，通过设置第一导杆和第一滑槽(也即第一凹槽和第三凹槽)的配合、以及第二导杆和第二滑槽(第二凹槽和第四凹槽)的配合，可以在外壳相对固定座滑动的过程中，起到导向的作用，从而使得外壳更加准确地沿Z轴方向滑动，也即外壳不容易发生偏移。
另外，通过将第一滑槽分成第一凹槽和第三凹槽设置，从而降低第一导杆与第一滑槽的装配难度。例如，可以先将第一导杆设置于第三凹槽内，再通过粘胶将第一导杆粘接于第三凹槽的槽壁，最后再将第一凹槽与第一导杆装配。
在一种可能的实现方式中，第一凹槽的槽壁呈“V”型，第二凹槽的槽壁呈弧形、“[”型或者U型，或者第一凹槽的槽壁呈弧形、“[”型或者U型，第二凹槽呈“V”型。
可以理解的是，在一种可能的实现方式中，通过设置第一凹槽的槽壁为“V”字型，使得第一凹槽的两个槽壁可以与第一导杆保持接触，第一凹槽的两个槽壁较容易夹紧第一导杆。外壳、第一导杆以及固定座连接更加稳定。此外，通过将外壳的第二凹槽设置为“[”型、圆形或者U型，从而使得第二凹槽的槽壁与第二导杆之间可以预留出一定的误差，以使第二导杆与第二凹槽不会因位置存在误差而不容易装配。
在一种可能的实现方式中，镜头组件包括第一磁吸件和第二磁吸件，第一磁吸件固定连接外壳，第二磁吸件固定连接固定座。导杆在第一磁吸件与第二磁吸件吸力下与外壳和固定座保持接触。
可以理解的是，通过将第一磁吸件固定连接外壳，第二磁吸件固定连接固定座，从而利用第一磁吸件与第二磁吸件在Y轴方向上产生的吸引力来使得外壳、第一导杆、第二导杆以及固定座紧密地保持接触。这样固定座不容易相对外壳晃动。
在一种可能的实现方式中，外壳设有第一固定槽，固定座设有第二固定槽。第一磁吸件位于第一固定槽内，第二磁吸件位于第二固定槽内。
可以理解的是，通过将第一磁吸件设置于第一固定槽内，从而一方面可以增加第一磁吸件与外壳的连接面积，从而提高第一磁吸件与外壳之间的连接牢固度，另一方面有利于镜头组件的小型化和轻型化设计。
另外，通过将第二磁吸件设置于第二固定槽内，从而一方面可以增加第二磁吸件与外壳的连接面积，从而提高第二磁吸件与外壳之间的连接牢固度，另一方面有利于进一步地实现镜头组件的小型化和轻型化设计。
在一种可能的实现方式中，导杆包括间隔设置第一导杆以及第二导杆，第一导杆和第二导杆位于固定座的同一侧；
第二磁吸件位于第一导杆和第二导杆之间，或者位于第一导杆的远离第二导杆的一侧，或者位于第二导杆的远离第一导杆的一侧。
可以理解的是，第二磁吸件、第一导杆和第二导杆的排布更加紧密，这样，外壳与固定座之间的作用力更大，外壳、第一导杆、第二导杆以及固定座之间的连接更加稳定。
在一种可能的实现方式中，镜头组件包括隧道磁阻传感器以及磁栅，隧道磁阻传感器和磁栅中的一者固定连接于外壳，另一者固定于固定座，隧道磁阻传感器用于检测磁栅在不同位置的磁场强度。
可以理解的是，当外壳相对固定座沿Z轴方向移动时，外壳可以带动磁栅相对固定座沿Z轴方向移动。隧道磁阻传感器可以检测磁栅所在位置的磁场强度。这样，当隧道磁阻传感 器检测到磁栅的磁场强度时，可以通过磁场强度来确定外壳的位移。可以理解的是，通过隧道磁阻传感器与磁栅的相互配合，从而实现准确地控制外壳相对固定座沿Z轴方向移动的位移，进而实现镜头组件的闭环设计。
另外，相较于通过采用霍尔传感器与磁铁的方案，在本实施方式中，通过采用隧道磁阻传感器与磁栅的配合的方案，可以准确测量位移较大的外壳。
在一种可能的实现方式中，第一镜头包括镜头盖板、第一镜筒和第一镜片。第一镜片的数量为多个。至少一片第一镜片固定在镜头盖板与第一镜筒之间。其余的第一镜片固定连接第一镜筒。
在一种可能的实现方式中，第二镜头包括第二镜筒和第二镜片。第二镜片固定连接第二镜筒。
在一种可能的实现方式中，驱动机构用于驱动固定座在镜头组件的光轴方向上滑动。
在一种可能的实现方式中，镜头组件包括第一缓冲件，第一缓冲件固定连接固定座的底面。这样，当外壳带动第二镜头沿Z轴的正方向移动。此时，第一缓冲件可以缓冲外壳的底板与固定座之间的碰撞力，以避免外壳的底板或者固定座撞坏。

在其他实施方式中，摄像头装饰件80也可以固定连接后盖202。此时，电子设备1可以不包括驱动装置90。
在其他实施方式中，电子设备1也可以不包括密封件91。此时，利用摄像头装饰件80的自身一些结构来密封摄像头装饰件80与安装孔203之间的缝隙。
在本实施方式中，摄像模组100位于电子设备1的内部。摄像模组100为直立式摄像模组，也即摄像模组100的光轴方向为Z轴方向摄像模组100可以为后置摄像模组或者前置摄像模组等。图1和图2示意了摄像模组100为后置摄像模组。

请参阅图14，图14是图5所示的镜头马达60在D-D线处的部分剖面图。第一导杆63a的长度延伸方向可以为Z轴方向。第一导杆63a设置于第一滑槽616内。第一导杆63a可以固定于固定座62的第三凹槽6272内。第一导杆63a可以相对第一凹槽6135滑动。可以理解的是，第一导杆63a也可以通过粘接或者焊接等方式固定于固定座62。在其他实施方式中，第一导杆63a可以与固定座62形成一体成型的结构件。
在其他实施方式中，第一凹槽6135也可以设置在固定座62。第三凹槽6272也可以设置在第一板件613。此时，第一导杆63a也可以固定于第一板件613的第三凹槽6272内。第一导杆63a相对固定座62的第一凹槽6135滑动。
请再次参阅图14，第二导杆63b的长度延伸方向可以为Z轴方向。第二导杆63b设置于第二滑槽617内。第二导杆63b可以固定于固定座62的第四凹槽6273内。第二导杆63b可以相对第二凹槽6136滑动。可以理解的是，第二导杆63b也可以通过粘接或者焊接等方式固定于固定座62。在其他实施方式中，第二导杆63b可以与固定座62形成一体成型的结构件。
在其他实施方式中，第二凹槽6136也可以设置在固定座62。第四凹槽6273也可以设置在第一板件613。此时，第二导杆63b也可以固定于第一板件613的第四凹槽6273内。第一导杆63a相对固定座62的第二凹槽6136滑动。
在本实施方式中，通过第一导杆63a和第一滑槽616的配合、以及第二导杆63b和第二滑槽617的配合，可以在外壳61相对固定座62滑动的过程中，起到导向的作用，从而使得外壳61相对固定座62的滑动方向更加准确，外壳61不容易发生偏移。另外，相较于通过簧片的形变来带动固定座62移动的方案，本实施方式通过第一导杆63a和第一滑槽616的配合、以及第二导杆63b和第二滑槽617的配合，可以不用受限于第一导杆63a和第二导杆63b， 外壳61相对固定座62滑动的距离可以更长。示例性地，外壳61可以相对固定座62沿Z轴方向滑动的最大距离可以为5毫米。此时，外壳61可以相对固定座62沿Z轴方向滑动的距离在0至5毫米的范围内。
结合图13所示，通过第二板件614的凸块6143的弧面与固定座62的避让槽6275配合，可以在外壳61相对固定座62滑动的过程中，起到进一步的导向作用。这样，在外壳61在相对固定座62滑动的过程中，外壳61更加的稳定，也即外壳61不容易发生倾斜。
请参阅图15，图15是图5所示的镜头马达60在E-E线处的部分剖面图。第一磁吸件66固定于第一板件613的第一固定槽6137内。第二磁吸件67固定于固定座62的第二固定槽6274内。第一磁吸件66与第二磁吸件67可以相互吸引。在本实施方式中，第一磁吸件66与第二磁吸件67可以在Y轴方向上产生吸引力。这样，第一板件613、第一导杆63a、第二导杆63b以及固定座62可以在吸力的作用下保持接触，此时，固定座62不容易相对第一板件613晃动。结合图14所示，由于第一凹槽6135的槽壁为“V”字型，使得当第一磁吸件66与第二磁吸件67在Y轴方向上产生吸引力时，第一凹槽6135的两个槽壁可以对第一导杆63a施加作用力，这样第一凹槽6135的两个槽壁可以夹紧第一导杆63a。第一板件613、第一导杆63a以及固定座62连接更加稳定。此外，通过将第一板件613的第二凹槽6136设置为“[”型、圆形或者U型，从而在X轴方向上，第二凹槽6136的槽壁与第二导杆63b之间可以预留出一定的误差，以使第二导杆63b与第二凹槽6136不会因位置存在误差而不容易装配。
请再次参阅图15，在本实施方式中，第一磁吸件66与第二磁吸件67的数量均为两个。两个第一磁吸件66一一对应地固定在两个第一固定槽6137内。两个第二磁吸件67一一对应地固定在两个第二固定槽6274内。这样，在Y轴方向上，第一板件613与固定座62之间的作用力更大，第一板件613、第一导杆63a、第二导杆63b以及固定座62之间的连接更加稳定。在其他实施方式中，第一磁吸件66与第二磁吸件67的数量不做具体地限定。
在一种实施方式中，第一磁吸件66和第二磁吸件67可以均为磁铁。
在一种实施方式中，第一磁吸件66和第二磁吸件67中的一者为磁铁，另一者为导磁件。
在本实施方式中，两个第二磁吸件67位于第一导杆63a和第二导杆63b之间。这样，两个第一磁吸件66与两个第二磁吸件67产生的吸引力较为集中，有利于提高第一板件613、第一导杆63a、第二导杆63b以及固定座62之间的连接稳定性。
在其他实施方式中，第二磁吸件67位于第一导杆63a的远离第二导杆63b的一侧。
在其他实施方式中，第二磁吸件67位于第二导杆63b的远离第一导杆63a的一侧。

请再次参阅图16，第一线圈64a和第二线圈64b均固定连接于固定座62。示例性地，第一线圈64a可以固定连接于固定座62的第三侧面625，并与第一磁铁65a相对设置。第二线圈64b可以固定连接于固定座62的第四侧面626，并与第二磁铁65b相对设置。可以理解的是，当第一线圈64a与第二线圈64b施加有信号时，第一磁铁65a可以与第一线圈64a配合，第二磁铁65b可以与第二线圈64b配合，从而推动外壳61相对固定座62，沿着X轴方向滑动。
在其他实施方式中，第一磁铁65a和第一线圈64a的固定位置可以对调。第二磁铁65b和第二线圈64b的固定位置可以对调。
请再次参阅图16，在本实施方式中，通过在外壳61上固定连接第一磁铁65a和第二磁铁65b，以及在固定座62上固定连接第一线圈64a和第二线圈64b，从而利用第一磁铁65a与第一线圈64a产生的洛伦力，以及第二磁铁65b与第二线圈64b产生的洛伦力来驱动外壳61相对固定座62，沿Z轴方向滑动。另外，结合图14所示，通过设置第一导杆63a和第一滑槽616的配合、以及第二导杆63b和第二滑槽617的配合，可以在外壳61相对固定座62滑动的过程中，起到导向的作用，从而使得外壳61更加准确地沿Z轴方向滑动，也即外壳61不容易发生偏移。另外，结合图15所示，通过将第一磁吸件66固定于第一板件613的第一固定槽6137内，第二磁吸件67固定于固定座62的第二固定槽6274内，从而利用第一磁吸件66与第二磁吸件67在Y轴方向上产生的吸引力来使得第一板件613、第一导杆63a、第二导杆63b以及固定座62紧密地连接。这样固定座62不容易相对第一板件613晃动。
请参阅图17，图17是图4所示的镜头组件60a在G-G线处的部分剖面图。在一种实施方式中，第一镜头71包括镜头盖板711、第一镜筒712和第一镜片713。第一镜片713的数量可以为一片，也可以为多片。当第一镜片713的数量为多片时，多片第一镜片713可以沿Z轴方向依次设置。示例性地，至少一片第一镜片713固定在镜头盖板711与第一镜筒712之间。其余的第一镜片713固定连接第一镜筒712。
本实施方式的第一镜片713的数量为三片。第一镜片713固定连接第一镜筒712。镜头盖板711固定连接第一镜筒712。示例性地，第一镜片713的第一片固定在镜头盖板711与第一镜筒712之间，也即第一镜片713的第一片还固定连接镜头盖板711。第一镜片713的其余片固定在第一镜筒712内。在其他实施方式中，第一镜片713的固定位置不做限定。
在一种实施方式中，第二镜头72包括第二镜筒721和第二镜片722。第二镜片722的数量可以为一片，也可以为多片。当第二镜片722的数量为多片时，多片第二镜片722可以沿Z轴方向依次设置。本实施方式的第二镜片722的数量为三片。第二镜片722固定连接第二镜筒721。
在一种实施方式中，第一镜头71固定连接固定座62。第一镜头71的至少部分位于固定座62的固定孔6271内。示例性地，第一镜头71的第一镜筒712可以通过粘接等方式固定连接于固定孔6271的孔壁。
在一种实施方式中，第二镜头72固定于外壳61的底板611。第二镜头72的像侧与底板611的透光孔6111相对设置。第二镜头72位于第一镜头71的像侧。
请再次参阅图17，图17是电子设备1处于弹出状态时，镜头组件60a的结构示意图。这样，当电子设备1处于弹出状态时，第二镜头72的至少部分可以位于固定座62的固定孔6271内。此时，第二镜头72靠近第一镜头72设置。
请参阅图18，图18是图2所示的电子设备1处于对焦状态的部分剖面图。第一镜头71 固定连接摄像头装饰件80。示例性地，第一镜头71的镜头盖板711通过粘接等方式固定连接摄像头装饰件80。
当电子设备1处于对焦状态时，第二镜头72的一小部分可以位于固定座62的固定孔6271内。此时，第二镜头72远离第一镜头71设置。换言之，在电子设备1处于对焦状态时，第一镜头71与第二镜头72之间的距离大于在电子设备1处于弹出状态时，第一镜头71与第二镜头72之间的距离。
可以理解的是，当电子设备1自弹出状态向对焦状态转换时，外壳61在第一磁铁65a与第一线圈64a，以及第二磁铁65b与第二线圈64b的驱动下，沿Z轴的负方向滑动。此时，外壳61可以带动第一磁铁65a、第二磁铁65b与第二镜头72沿Z轴的负方向移动。第二镜头72与第一镜头71之间的距离增大，第二镜头72与感光芯片20之间的距离减小。当电子设备1自对焦状态向弹出状态转换时，外壳61在第一磁铁65a与第一线圈64a，以及第二磁铁65b与第二线圈64b的驱动下，沿Z轴的正方向滑动。此时，外壳61可以带动第一磁铁65a、第二磁铁65b与第二镜头72沿Z轴的正方向移动。第二镜头72与第一镜头71之间的距离减小，第二镜头72与感光芯片20之间的距离增大。
可以理解的是，当电子设备1处于弹出状态时，摄像模组100如果可以正常拍摄，摄像模组100不用再对焦，此时，电子设备1的弹出状态也可以为电子设备1的对焦状态。
在本实施方式中，由于外壳61相对固定座62沿Z轴方向滑动的最大距离可以为5毫米，使得摄像模组100的最大对焦距离可以为5毫米。换言之，摄像模组100的对焦行程在0至5毫米的范围内。上文结合相关附图具体介绍了镜头组件60a的一种实施方式的结构。下文将结合相关附图再具体介绍镜头组件60a的其他设置方式。
首先结合相关附图具体介绍一种第一线圈64a与第二线圈64b与外部器件的电连接方式。
请参阅图19，图19是图6所示的马达电路板68在另一个角度下的结构示意图。马达电路板68包括第一部分681、第二部分682、第三部分683以及第四部分684。第二部分682连接在第一部分681与第三部分683之间。第一部分681与第三部分683相对设置。第四部分连接第二部分。
请参阅图20，图20是图6所示的马达电路板68、固定座62与底板611的组装示意图。马达电路板68固定连接于固定座62。示例性地，马达电路板68的第一部分681固定连接于固定座62的第三侧面625。马达电路板68的第三部分683固定连接于固定座62的第四侧面626。马达电路板68的第二部分682固定连接于固定座62的第二侧面624。
请参阅图20，并结合图12所示，马达电路板68的第四部分684可以穿过第二板件614和外壳61的第二侧板6123，伸出至外壳61的外部。马达电路板68的第四部分684可以用于与模组电路板10(请参阅图18)电连接。这样，模组电路板10和马达电路板68之间可以相互传输电信号。
请再次参阅图20，第一线圈64a固定于马达电路板68的第一部分681，且电连接于马达电路板68。这样，第一线圈64a、马达电路板68以及模组电路板10(请参阅图18)可以形成电流回路。
第二线圈64b固定于马达电路板68的第三部分683，且电连接于马达电路板68。这样，第二线圈64b、马达电路板68以及模组电路板10(请参阅图18)可以形成电流回路。
在其他实施方式中，镜头马达60也可以不包括马达电路板68。第一线圈64a可以通过导线电连接模组电路板10。第二线圈64b可以通过导线电连接模组电路板10。
其次下文将结合相关附图具体介绍镜头组件60a的一种闭环设置。
请参阅图21，并结合图20所示，图21是图5所示的镜头组件60a在另一个实施方式的部分剖面图。镜头马达60还可以包括隧道磁阻(Tunnel Magnetoresistance,TMR)传感器73以及磁栅74。隧道磁阻传感器73可以固定于马达电路板68，且电连接于马达电路板68。磁栅74可以固定于外壳61。隧道磁阻传感器73可以与磁栅74相对设置。示例性地，隧道磁阻传感器73可以固定于马达电路板68的第二部分682。磁栅74可以固定于外壳61的第二板件614。在其他实施方式中，隧道磁阻传感器73与磁栅74的位置可以对调。
在本实施方式中，隧道磁阻传感器73用于检测磁栅74在不同位置的磁场强度。当外壳61相对固定座62沿Z轴方向移动时，外壳61可以带动磁栅74相对固定座62沿Z轴方向移动。隧道磁阻传感器73可以检测磁栅74所在位置的磁场强度。这样，当隧道磁阻传感器73检测到磁栅74的磁场强度时，可以通过磁场强度来确定外壳61的位移。可以理解的是，通过隧道磁阻传感器73与磁栅74的相互配合，从而实现准确地控制外壳61相对固定座62沿Z轴方向移动的位移，进而实现镜头组件60a的闭环设计。
另外，相较于通过采用霍尔传感器与磁铁的方案，在本实施方式中，通过采用隧道磁阻传感器73与磁栅74的配合的方案，可以准确测量位移较大的外壳61。
在一种实施方式中，镜头组件60a可以包括驱动芯片(也称为驱动IC)。驱动IC电连接第一线圈64a和第二线圈64b。驱动芯片可以向第一线圈64a和第二线圈64b传输电流。驱动芯片可以位于第一线圈64a所围的区域内，或者位于第二线圈64b所围的区域内。
在一种实施方式中，隧道磁阻传感器73可以集成在IC芯片中。此时，IC芯片具有隧道磁阻传感器73的功能，也即IC芯片可以用于检测磁栅74在不同位置的磁场强度。
请参阅图22，图22是图4所示的镜头组件60a在另一种实施方式的部分剖面图。在一种实施方式中，固定座62设有第一缓冲件75。第一缓冲件75固定连接固定座62的底面622。这样，当摄像模组100自对焦状态向弹出状态移动时，外壳61可以带动第一磁铁65a、第二磁铁65b与第二镜头72沿Z轴的正方向移动。此时，第一缓冲件75可以缓冲外壳61的底板611与固定座62之间的碰撞力，以避免外壳61的底板611或者固定座62撞坏。在其他实施方式中，第一缓冲件75也可以固定连接外壳61的底板611的顶面。
示例性地，第一缓冲件75可以为橡胶、弹簧、弹片、硅胶或者其他具有弹性的部件。本实施方式的第一缓冲件75为橡胶。
请参阅图23，图23是图2所示的摄像模组100在另一种实施方式的部分剖面图。在一种实施方式中，摄像模组100包括第二缓冲件76。第二缓冲件76固定连接于外壳61的底板611的底面622。这样，当摄像模组100自弹出状态向非弹出状态转换时，摄像头装饰件80可以带动镜头组件60a沿Z轴的负方向运动。此时，第二缓冲件76可以缓冲外壳61的底板611与底座50之间的碰撞力，以避免外壳61的底板611或者底座50撞坏。
示例性地，第二缓冲件76可以为橡胶、弹簧、弹片、硅胶或者其他具有弹性的部件。
上文结合相关附图具体介绍了一种电子设备1的实施例。下文将结合相关附图再介绍一种电子设备1的结构。与上文实施例相同的技术内容不再赘述。
请参阅图24至图26，图24是本申请另一种实施例提供的电子设备1的剖面图。图25是图24所示的电子设备1处于弹出状态下的剖面图。图26是图24所示的电子设备1处于对焦状态下的剖面图。在本实施方式中，镜头组件60a的第一镜头71与摄像头装饰件80分开设置。换言之，镜头组件60a的第一镜头71不再固定连接摄像头装饰件80。本实施方式的电子设备1也具有三种状态，摄像模组100也相应具有三种状态。换言之，摄像模组100具有非弹出状态、弹出状态以及对焦状态。
请再次参阅图24，当电子设备1处于非弹出状态(也即摄像模组100处于非弹出状态)时，摄像模组100在Z轴方向上，与摄像头装饰件80之间的距离为第一距离。请再次参阅图25，当电子设备1处于弹出状态(也即摄像模组100处于弹出状态)时，摄像模组100在Z轴方向上，与摄像头装饰件80之间的距离为第二距离。第二距离大于第一距离。可以理解的是，本实施方式通过额外增加一个摄像模组100的状态(也即摄像模组100的弹出状态)，从而使得当摄像模组100在工作过程中，在Z轴方向上具有较大的调焦空间。具体地下文将结合相关附图具体描述。
请再次参阅图24和图25，当电子设备1自非弹出状态向弹出状态转换时，驱动装置90驱动摄像头装饰件80相对后盖202沿Z轴的正方向运动，摄像头装饰件80的至少部分可以运动至安装孔203的外部。此时，摄像头装饰件80与摄像模组100之间的距离增大。当电子设备1自弹出状态向非弹出状态转换时，驱动装置90驱动摄像头装饰件80相对后盖202沿Z轴的负方向运动，摄像头装饰件80的至少部分可以运动至安装孔203的内侧。此时，摄像头装饰件80与摄像模组100之间的距离减小。
请再次参阅图26，当电子设备1处于对焦状态时，第二镜头72远离第一镜头71设置。换言之，在电子设备1处于对焦状态时，第一镜头71与第二镜头72之间的距离大于在电子设备1处于弹出状态时，第一镜头71与第二镜头72之间的距离。
可以理解的是，当电子设备1处于弹出状态时，摄像模组100如果可以正常拍摄，摄像模组100不用再对焦，此时，电子设备1的弹出状态也可以为电子设备1的对焦状态。
可以理解的是，当电子设备1自弹出状态向对焦状态转换时，固定座62在第一磁铁65a与第一线圈64a，以及第二磁铁65b与第二线圈64b的驱动下，沿Z轴的正方向滑动。此时，固定座62可以带动第一线圈64a、第二线圈64b与第一镜头71沿Z轴的正方向移动。第一镜头71与第二镜头72之间的距离增大，第一镜头71远离感光芯片20。当电子设备1自对焦状态向弹出状态转换时，固定座62在第一磁铁65a与第一线圈64a，以及第二磁铁65b与第二线圈64b的驱动下，沿Z轴的负方向滑动。此时，固定座62可以带动第一线圈64a、第二线圈64b与第一镜头71沿Z轴的负方向移动。第一镜头71与第二镜头72之间的距离减小，第一镜头71靠近感光芯片20运动。
在本实施方式中，通过固定座62相对外壳61的滑动，来使得第一镜头71与第二镜头72之间的距离增大或者减小，从而实现摄像模组100的对焦。本实施方式的摄像模组100的对焦行程较大。示例性地，摄像模组100的最大对焦距离可以为5毫米。也即，摄像模组100的对焦行程在0至5毫米的范围内。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
