请参阅图1至图6，本申请实施方式的终端100包括机壳10、装饰部件20和镜头模组30。机壳10设有收容腔11，收容腔11通过通孔12与外界连通。装饰部件20安装于通孔12，装饰部件20包括与通孔12对应的装饰盖板21，装饰盖板21能够运动以伸出机壳10外或缩回至通孔12内。镜头模组30安装于收容腔11内，镜头模组30包括感光元件32和镜头31，感光元件32用于将依次穿过装饰盖板21及镜头31的光信号转换为电信号，镜头31能够沿镜头模组30的光轴运动。其中：当镜头模组30处于第一状态时，装饰盖板21与感光元件32之间保持第一距离D1，感光元件32与镜头31之间保持第二距离D2；当镜头模组30处于第二状态时，装饰盖板21与感光元件32之间保持第三距离D3，镜头31与感光元件32之间保持第四距离D4，第三距离D3大于第一距离D1，第四距离D4大于第二距离D2；当镜头模组30处于第三状态时，装饰盖板21与感光元件32之间保持第五距离D5，镜头31与感光元件32之间具有第六距离D6，第五距离D5大于或等于第三距离D3，第六距离D6小于、大于或等于第四距离D4且大于第二距离D2。
本申请实施方式的终端100中，镜头31可沿镜头31的光轴运动，装饰盖板21能够运动以伸出机壳10外，在镜头模组30处于第一状态时，装饰盖板21与感光元件32之间的第一距离D1不仅小于镜头模组30处于第二状态的第三距离D3，还小于第三状态时的第五距离D5，感光元件32与镜头31之间的第二距离D2不仅小于镜头模组30处于第二状态时的第四距离D4，还小于第三状态时的第六距离D6，如此，镜头模组30处于第一状态时，镜头31与装饰盖板21的组合厚度较小，使得机壳10不用较厚即可容纳镜头31和装饰盖板21，进而使得终端100可以制造的更薄。
终端100可以是手机、平板、智能手表、笔记本电脑、智能手环等。请结合图1，本申请以终端100是手机为例进行示例性说明，可以理解，本申请的终端100并不限于手机，还可以是其他。镜头模组30可以为设置于手机的前置摄像头，镜头模组30也可以为设置于手机的后置摄像头，在此不做限制，本申请实施方式以镜头模组30设置于手机的后置摄像头为例进行示例性说明。
目前，为了使镜头模组可正常工作，镜头与感光元件之间的距离至少为0.75mm，需要预留镜头的调焦行程(即，镜头与装饰盖板之间的距离)至少为0.64mm，则目前方案中，装饰盖板与感光元件之间的距离至少应为0.64+0.75+镜头的厚度。
其中，本申请实施例中，第一状态可以指的是镜头模组30不需要进行工作(即，终端100不需要进 行拍摄时的状态，或者终端100的默认状态)，镜头模组30和装饰部件20可以处于极限压缩状态，例如，装饰盖板21的外表面可与机壳10的后盖14的外表面平齐。在第一状态时，装饰盖板21和镜头31之间的距离可等于0mm，镜头31与感光元件32之间的第一距离D2可为镜头31与感光元件32之间的最小安全距离0.2mm，则在第一状态时装饰盖板21与感光元件32之间的第一距离D1为0mm+0.2mm+镜头31的厚度，相较于上述目前0.64mm+0.75mm+镜头31的厚度，本申请的装饰盖板21和感光元件32之间的距离减少了1.39mm-0.2mm＝1.19mm，进而本申请的终端100相对于目前的终端的厚度至少可以减少1.19mm，则本申请的终端100可以制造得更薄、或者镜头模组30与装饰部件20不会凸出于机壳10，终端100更加美观。
第二状态可以指的是镜头模组30可工作的状态(例如镜头模组30的短焦状态、或镜头模组30的默认状态)，在第二状态时镜头模组30可成像。在由第一状态切换至第二状态的过程中，首先，镜头模组30可相对感光元件32保持固定装饰盖板21可相对机壳10朝远离感光元件32的方向运动，使得装饰盖板21与感光元件32之间的距离可增大至第三距离D3，第三距离D3可大于第一距离D1，以使镜头31有较充足的空间沿镜头31的光轴相对机壳10朝远离感光元件32的方向运动，接着，镜头31可相对感光元件32运动，使镜头31与感光元件32之间的距离可增大至第四距离D4，第四距离D4可大于第二距离D2，以使镜头31可与感光元件32配合使得镜头模组30可成像。在一个例子中，镜头31与感光元件32之间的第四距离D4可为镜头31与感光元件32之间的最小可成像距离，例如第四距离D4可为0.6mm。
第三状态可以指的是镜头模组30可调焦状态或者长焦状态，在第三状态为镜头模组30的可调焦状态时，镜头31可沿光轴运动以进行调焦；在第三状态为镜头模组30的长焦状态时，镜头31与感光元件32之间的距离可达到最大距离。在由第二状态切换至第三状态的过程中，装饰盖板21可相对机壳10朝远离感光元件32的方向运动或者装饰盖板21可保持不动，使得装饰盖板21和感光元件32之间的距离变为第五距离D5，第五距离D5可大于或等于第三距离D3。在由第二状态切换至第三状态的过程中，镜头31可沿镜头31的光轴运动，以实现调焦，使得镜头31与感光元件32之间的距离可调整为第六距离D6，其中，第六距离D6可大于第二距离D2，以使镜头模组30可成像，并且第六距离D6可小于、大于或等于第四距离D4(此时，第四距离D4不为镜头31与感光元件32之间的最小可成像距离)，以实现短焦、长焦、默认焦距。
在一个例子中，由第二状态切换至第三状态的过程中，装饰盖板21可相对机壳10朝远离感光元件32的方向运动，装饰盖板21和感光元件32之间的距离可增大至第五距离D5，镜头31可沿镜头31的光轴运动，以实现镜头模组30的调焦。可以理解，第五距离D5大于第三距离D3，增大了镜头31的可运动空间，便于镜头模组30可实现更长的焦距。
在另一个例子中，由第二状态切换至第三状态的过程中，装饰盖板21可相对感光元件32保持不动，装饰盖板21与感光元件32之间的第五距离D5与第二状态时的第三距离D3相同，镜头31可沿镜头31的光轴运动，以调整镜头模组30的焦距。可以理解，在第二状态时，装饰盖板21可运动至装饰盖板21的可运动最远距离，以便于镜头31可以具有足够的运动空间；或者，在第三状态时，装饰盖板21与感光元件32之间的距离已足够镜头31运动，不需要再朝远离机壳10的方向运动。
请结合图4至图6，在某些实施方式中，在镜头模组30处于第一状态时，第一距离D1为镜头31与装饰盖板21之间的距离+镜头31的高度+D2，第二距离D2＝0.2mm；在镜头模组30处于第二状态时，第三距离D3＝D4+镜头31与装饰盖板21之间的距离+镜头的高度，D4＝0.6mm；在镜头模组处于第三状态时，第五距离D5＝D4+镜头与装饰盖板之间的距离+镜头31的高度，第四距离D4为在0.6mm至1mm之间的任意距离值，例如，0.6mm、0.7mm、0.75mm、0.8mm、0.9mm、1.0mm或更多数值。
在镜头模组30由第一状态切换至第二状态及第二状态切换至第三状态的过程中，镜头31和装饰盖板21均会相对感光元件32运动，则容易导致镜头31部和装饰盖板21运动产生干涉而使镜头31和装饰盖板21碰撞而发生损坏。
在一些实施方式中，镜头31和装饰盖板21可相互独立运动。请结合图4至图6，镜头模组30由第一状态切换至第二状态(即，从图4所示的状态切换至图5所示的状态)和镜头模组30由第二状态切换至第三状态时(即，从图5所示的状态切换至图6所示的状态)，装饰盖板21运动的起始时刻可以早于镜头31运动的起始时刻，则镜头31开始运动时装饰盖板21已经运动了一段距离，可以避免镜头模组30由第一状态切换至第二状态的过程中，镜头31与装饰盖板21产生碰撞。例如，在装饰部件20运动了第一预设时长后，镜头31才开始运动；或者，装饰部件20运动至第一预设距离时，镜头31才开始运动。
在镜头模组30由第三状态或第二状态切换至第一状态时(即，从图6或图5所示的状态切换至图4所示的状态)，装饰盖板21运动的起始时刻晚于镜头31运动的起始时刻，则装饰盖板21开始运动时镜头31已经运动了一段距离，进而装饰盖板21运动时不易与镜头31发生碰撞，保证了镜头模组30状态切换时的安全性。例如，在镜头31运动了第二预设时长后，装饰部件20开始运动；或者，镜头31运动至第二预设距离时，装饰部件20开始运动。
更具体地，请继续参阅图4至图6，在一个例子中，镜头模组30由第一状态切换至第二状态和镜头模组30由第二状态切换至第三状态时，装饰盖板21运动的终止时刻早于镜头31运动的起始时刻，则在镜头31开始运动时，装饰盖板21已经运动至目标位置(距离感光元件32第三距离D3或第五距离D5)不再运动，此时镜头31与装饰盖板21之间的距离比较充足，镜头31运动不易与装饰盖板21发生碰撞。当镜头模组30由第二状态或第三状态切换至第一状态时，装饰盖板21运动的起始时刻晚于镜头31运动的终止时刻，则在装饰盖板21开始运动时，镜头31已经运动至目标位置(距离感光元件32第二距离D2)不再运动，此时装饰盖板21与镜头31之间的距离比较充足，装饰盖板21运动不易与镜头31发生碰撞。
在另一个例子中，当镜头模组30由第一状态切换至第二状态、和镜头模组30由第二状态切换至第三状态时，装饰盖板21运动的终止时刻不早于镜头31运动的起始时刻，则镜头31运动的起始时刻位于装饰盖板21运动的起始时刻和终止时刻之间，如此，可以缩短镜头模组30由第一状态切换至第二状态，和由第二状态切换至第三状态的时长，提高终端100的响应速度，进而增强了用户的使用体验。当镜头模组30由第二状态或第三状态切换至第一状态时，装饰盖板21运动的起始时刻不晚于镜头31运动的终止时刻，则装饰盖板21运动的起始时刻位于镜头31运动的起始时刻和终止时刻之间，如此，可以缩短镜头模组30第二状态或第三状态切换至第一状态的时长，提高终端100的响应速度，进而增强用户的使用体验。
进一步地，镜头模组30由第一状态切换至第二状态、和镜头模组30由第二状态切换至第三状态时，装饰盖板21的运动速度可以大于或者等于镜头31的运动速度，更好地避免了镜头31与装饰盖板21产生碰撞。当镜头模组30由第二状态或第三状态切换至第一状态时，镜头31的运动速度可以大于或者等于装饰盖板21的运动速度，更好地避免了镜头31与装饰盖板21产生碰撞。
需要说明的是，上述实施例中镜头模组30由第一状态切换至第二状态，及由第一状态切换至第三状态，可以根据用户在终端100上的输入的控制指令确定，例如，获取到用户在终端100上输入的需要拍摄的指令时(例如用户点击了相机图标、用户需要与他人视频时等)，用户在相机界面调整了变焦倍数等指令)。上述实施例中镜头模组30由第三状态或第二状态切换至第一状态，也可以根据终端100用户在终端100上的输入的控制指令确定，例如，在终端100处于拍摄状态时(第二状态或第三状态)，如果获取到用户结束了拍摄(例如用户退出了相机应用、用户结束了与他人的视频)。
请参阅图4至图6，在某些实施方式中，装饰盖板21具有运动上限位置和运动下限位置，装饰盖板21可以在运动上限位置和运动下限位置之间运动，镜头模组30处于运动下限位置时，装饰盖板21可位于下限位置，以极限压缩装饰盖板21和镜头模组30的组合厚度；镜头模组30处于第二状态和第三状态时，装饰盖板21可位于上限位置，以使镜头31能够有充足的运动空间，以使镜头31能够到达工作位置，并具有预设的对焦焦段，镜头模组30可以输出图像数据，终端100可以以预设的对焦焦段成像。预设的对焦焦段可以通过用户在终端100上输入的指令确定，例如用户确定相机的变焦倍率后，镜头31运动至与该变焦倍率对应的工作位置。
具体地，镜头31的工作位置可以包括预览成像位置和正式成像位置，在镜头31运动至预览成像位置时，终端100可以输出目标场景的预览图像数据，然后镜头31可以继续朝正式成像位置运动，镜头31运动至正式成像位置时，终端100可以输出目标场景的正式图像数据，由此，可以避免因为镜头31运动距离较长而导致终端100的显示界面较长时间处于黑屏状况，提升了用户的使用感受。在一个例子中，镜头31处于预览成像位置时，镜头模组30处于第二状态；镜头31处于正式成像位置时，镜头模组30处于第三状态。
其中，镜头31可以具有多个不同的对焦位置，镜头31在每个对焦位置时具有不同的对焦焦段，以使终端100能够实现不同的成像倍率。在装饰盖板21位于上限位置时，镜头31可以位于任一对焦位置，以实现对应的成像倍率。例如，对焦位置的数量可以为三个，分别为第一对焦位置、第二对焦位置和第三对焦位置；在镜头31位于第一对焦位置时，终端100能够实现广角模式；在镜头31位于第二对焦位 置时，终端100能够实现1倍变焦；在镜头31位于第三对焦位置时，终端100能够实现5倍变焦。当然，镜头31的对焦位置并不限于第一对焦位置、第二对焦位置和第三对焦位置，还可以是其他，例如第四对焦位置、第五对焦位置等。
当然，由于在不同的变焦倍数时，镜头31运动的距离不同，因此装饰盖板21可以根据用户输入的变焦倍数运动对应的距离，使得镜头31可以实现对应的焦段，同时装饰盖板21伸出机壳10的距离不会过多。例如，在需要以第一倍率成像时，镜头31需要运动第一距离，则装饰盖板21运动的距离可大于或等于第一距离，以使镜头31运动第一距离不会与装饰盖板21发生碰撞；在需要以第二倍率成像时，镜头31需要运动第二距离，则装饰盖板21运动的距离可大于或等于第二距离，以使镜头31运动第二距离不会与装饰盖板21发生碰撞。
在一个实施例中，在镜头模组30由第一状态切换至第三状态时，在镜头31或装饰盖板21运动的过程中，可以先完成相机的初始化及获取图像前的准备工作，以使镜头31运动至工作位置时，相机可以马上进行成像，提升了终端100的响应速度。

请参阅图9至图11，装饰圈22可以设有安装槽221，装饰盖板21可以通过背胶、粘接等方式固定安装在安装槽221内，以使装饰盖板21不易从安装槽221内脱离。其中，装饰圈22可以是由硅胶、塑料、金属等材料制成。当然，装饰圈22和装饰盖板21可以为一体成型件，例如，装饰圈22和装饰盖板21可以通过锻造、铸造、注塑等方式一体成型。进一步地，装饰圈22可开设有镜孔222，镜孔222可以与镜头31相对，以使穿过装饰盖板21的光线可以通过镜孔222进入到镜头31内；或者，镜头31可以部分伸入镜孔222，以减小终端100的厚度。
请继续参阅9至图11，终端100还可包括第一驱动部件40，第一驱动部件40可以用于驱动装饰部件20运动。第一驱动部件40可以与装饰部件20连接，第一驱动部件40可以驱动装饰部件20在装饰部件20的运动下限位置和运动上限位置之间运动，使得装饰部件20可到达下限位置与上限位置之间的任意位置，例如，第一驱动部件40可驱动装饰盖板21由图11所示的位置运动至如图12所示的位置，或者第一驱动部件40可驱动装饰盖板21由图12所示的位置运动至如图11所示的位置。第一驱动部件40具体可以驱动装饰盖板21沿镜头模组30的光轴朝远离及靠近镜头模组30的感光元件32运动。

进一步地，请参阅图10至图12，在某些实施方式中，装饰部件20还可包括密封件23，密封件23可以套设装饰圈22，或者装饰圈22可以安装在密封件23内，密封件23可以密封装饰圈22与机壳10之间的间隙，使得灰尘、水汽等物质不易从装饰圈22和机壳10之间的间隙进入到收容腔11内。密封件23可以是由硅胶等材料制成，装饰圈22可相对密封件23运动，装饰圈22运动时密封件23不跟随装饰圈22运动，以使装饰圈22运动过程中密封件23仍然可以密封装饰圈22与机壳10之间的间隙。
请参阅图13至图15，镜头模组30包括镜头31和感光元件32。请结合图8，感光元件32可以用于接收依次穿过装饰盖板21和镜头31的光信号，并将接收到的光信号转换为电信号。在镜头模组30由第一状态切换至第二状态的过程中、由第二状态切换至第三状态的过程中、及第三状态或第二状态切换至第一状态的过程中，感光元件32始终保持固定不动。
镜头31可以包括一个或多个镜片，镜头31可以包括凹透镜和凸透镜等镜片，镜头31可以用于将穿过装饰部件20的光线会聚至感光元件32，以使感光元件32可以接收到更加充足的光线，进而镜头模组30成像更加清晰。镜头31可以沿镜头模组30的光轴运动，以调整镜头模组30的焦距。
请参阅图4、图14及图15，镜头模组30还可包括支架33，感光元件32可以收容于支架33内。支架33可包括顶壁，顶壁可开设有进光孔，穿过镜头31的光线可以经进光孔进入到感光元件32内。在一个例子中，在镜头模组30处于第一状态时，镜头31可以与支架33相接触，且镜头31与感光元件32间隔；在镜头模组30处于第二状态和第三状态时，镜头31可以与支架33相间隔，以便于可以调整镜头31的后焦。
进一步地，请参阅图14和图15，镜头模组30还可包括第二驱动部件34，第二驱动部件34可以安装于支架33，至少部分镜头31收容于第二驱动部件34，第二驱动部件34可以驱动镜头31沿镜头31的光轴运动。第二驱动部件34可驱动镜头31在距离感光元件32第二距离D2(第一位置)至距离感光元件32第六距离D6(第二位置)之间运动，使得镜头31可到达第一位置和第二位置之间的任意位置。
其中，可以是部分镜头31收容于第二驱动部件34内，也可以是整个镜头31收容于第二驱动部件34内。在镜头模组30由第一状态逐步切换至第二状态时，第二驱动部件34可以驱动镜头31沿镜头31的光轴朝远离感光元件32的方向运动，以增大镜头31与感光元件32之间的距离至第四距离D4。在镜头模组30由第二状态逐步切换至第三状态时，第二驱动部件34可以继续驱动镜头31沿镜头31的光轴朝远离或靠近感光元件32的方向运动，以调整镜头31与感光元件32之间的距离至第六距离D6。在镜头模组30由第三状态切换至第一状态时，第二驱动部件34可以驱动镜头31沿镜头31的光轴朝靠近感光元件32的方向运动，以减小镜头31与感光元件32之间的距离至第四距离D4和第二距离D2，进而压缩镜头模组30的厚度。
本实施例中，镜头模组30通过一个第二驱动部件34实现由第一状态切换至第二状态时镜头31的调整、及第二状态切换至第三状态时镜头31的调整、及第三状态切换至第一状态时镜头31的调整，镜头31运动的精确度更高，且镜头模组30的一体性更好。
具体地，请参阅图14，第二驱动部件34可包括固定件341、可动件342及第二驱动件343。固定件341可以固定安装于支架33，固定件341可设有第一容置腔3411，可动件342可活动收容于第一容置腔3411内，可动件342在第一容置腔3411内沿镜头31的光轴运动。可动件342设有第二容置腔3421，至少部分镜头31可以收容于第二容置腔3421，可动件342运动时可带动镜头31沿光轴运动。
更具体地，第二驱动件343可以包括线圈3431和磁铁3432。在一个例子中，线圈3431安装于固定件341，磁铁3432安装于可动件342，线圈3431通电后能够产生第一磁场，磁铁3432具有第二磁场，第一磁场和第二磁场可以相互作用而产生电磁力，由于固定件341固定不动，则线圈3431将固定不动，那么磁铁3432在电磁力的作用下可移动，进而带动可动件342移动，使得安装于可动件342内的镜头31移动。
在另一个例子中，线圈3431安装于可动件342，磁铁3432安装于固定件341，线圈3431通电后能够产生第一磁场，磁铁3432具有第二磁场，第一磁场和第二磁场可以相互作用而产生电磁力，由于固定件341固定不动，磁铁3432将固定不动，则线圈3431在电磁力的作用下可以移动，进而带动可动件342移动，使得安装于可动件342内的镜头31移动。
请继续参阅图14，可动件342的侧壁3422可以设有第一凹槽3423，磁铁3432或线圈3431可以安装于第一凹槽3423内，固定件341的侧壁3412上设有第二凹槽3413，线圈3431或磁铁3432可以安装 于第二凹槽3413，磁铁3432和线圈3431可以相对设置，以使线圈3431通电后，线圈3431和磁铁3432可以产生电磁力。
更具体地，磁铁3432的数量可为两个，分别为第一磁铁和第二磁铁，线圈3431的数量也可为两个，分别为第一线圈和第二线圈；在一个例子中，第一磁铁和第二磁铁可以分别安装于可动件342的相邻的两个侧壁3422上，第一线圈和第二线圈可以分别安装于固定件341的与第一磁铁和第二磁铁相对应的两个侧壁3412。或者，第一磁铁和第二磁铁可以分别安装于可动件342的相对的两个侧壁3422上，第一线圈和第二线圈可以分别安装于固定件341的与第一磁铁和第二磁铁相对应的两个侧壁3412。第二驱动件343通过设置第一磁铁和第二磁铁，可以增强电磁力，使得可动件342和固定件341的移动速度可以得到提升，进而减少了镜头31的运动时间，提高了镜头模组30的响应速度。
当然，在其他实施例中，磁铁3432和线圈3431可以均为一个，磁铁3432可以安装于可动件342的任意一个侧壁3422上，线圈3431可以安装于固定件341的与磁铁3432相对应的侧壁3412上。或者，磁铁3432和线圈3431的数量可以为三个，三个磁铁3432可以安装于可动件342的任意三个侧壁。线圈3431可以安装于固定件341的与磁铁3432相对应的侧壁上。或者，磁铁3432和线圈3431的数量可以为四个，四个磁铁3432分别安装于可动件342的四个侧壁，四个线圈3431可以安装于固定件341的四个侧壁上，此时驱动力量更大且更均匀，使得镜头31的运动更快捷且更稳定。
请参阅图14，在某些实施方式中，第二驱动部件34还可包括两组滚珠344，两组滚珠344可设置于固定件341与可动件342之间，每组滚珠344中滚珠3441的数量可为多个，例如每组滚珠344可包括2个、3个、4个、5个、6个或更多个的滚珠3441，每组滚珠344中的多个滚珠3441可以沿平行于光轴的方向依次设置。两组滚珠344可以位于第二驱动部件34的同一侧，并且该两组滚珠344关于该侧的中心轴对称分布。第二驱动部件34通过设置两组滚珠344，可动件342可以通过两组滚珠344相对固定件341运动，减少了可动件342与固定件341之间的摩擦力，并且两组滚珠344对称分布，使得两组滚珠344可以起到相互平衡的作用，进而可动件342在运动时不易发生倾斜。
具体地，请结合图16，固定件341或者可动件342开设有两个导槽345，两组滚珠344可以分别位于两个导槽345内，两组滚珠344可以分别在两个导槽345内沿导槽345运动。其中，导槽345的延伸方向可以与光轴相同，以使每组滚珠344可以沿光轴的方向运动，进而带动镜头31沿光轴运动，使得镜头31在运动的过程中光轴始终保持不变(不倾斜)。在一个例子中，请结合图14，固定件341上开设有两个第一子导槽3451，可动件342开设有两个第二子导槽3452，第一子导槽3451和第二子导槽3452共同形成导槽345，滚珠344可以安装于导槽345内，并与固定件341和可动件342接触。
在一个实施例中，两个导槽345的长度不同，两组滚珠344包括的滚珠344的数量可以不同，例如第一组滚珠344可以包括两个滚珠344，第一组滚珠344安装于短导槽，第二组滚珠344可以包括三个滚珠344，第二组滚珠344安装于长导槽，如此，使得可动件342和固定件341之间的活动更加顺畅且可动件342不易倾斜，避免了在短导槽内设置三个滚珠344，而使三个滚珠344容易相互摩擦，导致可动件342运动不顺畅，同时也避免了在长导槽内设置两个滚珠344，导致可动件342在长行程运动时发生倾斜的现象。
如果导槽345的长度较长时，可动件342运动过程中导槽345内的滚珠344容易滚在一起，例如所有的滚珠344均位于导槽345的中间区域，而导致导槽345的两端没有滚珠344，可动件342容易发生左右倾斜，使得收容于可动件342内的镜头31的光轴容易发生倾斜，而影响镜头模组30的成像效果。
请参阅图16，在一些实施方式中，每个导槽345内均可以设有凸起3453，凸起3453可以将每个导槽345分隔成第一腔3454和第二腔3455，每组滚珠344中的一部分滚珠344收容于对应的第一腔3454，每组滚珠344中的另一部分滚珠344收容于对应的第二腔3455。如此，通过设置凸起3453，使得可动件342运动时滚珠344不易滚在一起，保证了可动件342长行程运动时的稳定性。
其中，凸起3453可以设置在导槽345的中间位置，以使可动件342更不易发生倾斜。可动件342可以形成有凸起3453，或者固定件341可以形成有凸起3453。另外，第一腔3454和第二腔3455内的滚珠344可以相同，以使第一腔3454和第二腔3455的支撑力相同，可动件342运动时更加稳定。并且，在其他实施方式中，凸起3453的数量还可以为多个，例如两个，两个凸起3453可以将导槽345分为第一腔、第二腔和第三腔，多个滚珠344可以任意分配在第一腔、第二腔和第三腔中。
请一并参阅图14、图15及图17，在一些实施方式中，第二驱动部件34还可包括两个沿镜头31的光轴延伸的导柱346，每个导柱346均可以穿设固定件341和可动件342，可动件342可以沿导柱346相 对固定件341运动。通过设置两个导柱346，导柱346可以为可动件342提供持续的支撑，可动件342在长行程运动时两个导柱346可相互配合，使得可动件342不会发生倾斜。其中，两个导柱346可以位于可动件342的同一侧或者两个导柱346可以设置在可动件342的对角线位置。
请参阅图14和图15，第二驱动部件34还可以包括减振组件347，减振组件347可以安装于可动件342，减振组件347包括减振片3471和多个减振柱3472，多个减振柱3472穿设开设于减振片3471的第一孔和开设于可动件342的第二孔，减振片3471和减振柱3472可以降低可动件342运动时而产生的噪音。
进一步地，第二驱动部件34还可以包括罩壳348，罩壳348可以罩设固定件341，同时可以固定减振组件347与可动件342，以及固定磁铁3432和线圈3431，镜头31可以部分伸出罩壳348。
当然，镜头31的驱动方式并不限于上述的第二驱动部件34所示的驱动方式，还可以是其他方式，例如可以是类似于装饰部件20的驱动方式，或者其他类型的驱动方式，例如通过齿轮齿条传动的方式驱动镜头31运动，在此不做详细描述，也不做具体限制。
请参阅图18，支架33的顶壁331可包括相背的第一侧3311和第二侧3312，顶壁331的第一侧3311背离感光元件32，顶壁331的第二侧3312与感光元件32相对，镜头模组30还可包括滤光片35，滤光片35可以允许穿过镜头31而到达滤光片35的光线中的预设波段的光线穿过滤光片35而进入感光元件32，例如，预设波段可为红外光的波段，则滤光片35可以允许红外光通过；或者，预设波段为紫外光的波段，则滤光片35可以允许紫外光通过。可以根据实际需求选择对应的滤光片35，从而实现目标成像效果。
在一个例子中，滤光片35设置于顶壁331的第一侧3311，如图18所示。在另一个例子中，滤光片35设置在顶壁331的第二侧3312，如图19所示，如此，在镜头模组30处于第一状态时，镜头31与感光元件32之间的安全距离可以更小，进而镜头31与感光元件32之间的第二距离D2可以更小，从而使得镜头模组30处于第一状态时镜头模组30的厚度更薄，从而使得终端100的厚度可以制造得更小。
在某些实施方式中，请参阅图20，镜头模组30还可以不设置滤光片35，此时，装饰盖板21、和\或镜头31的镜片中可设有滤光层(图未示)，滤光层可以允许到达滤光层的光线中预设波段的光线穿过滤光层，从而使得装饰盖板21、和\或镜头31可以具有滤光功能，并且由于没有滤光片35，不用考虑镜头31与滤光片35之间的安全距离，使得镜头模组30处于第一状态时，镜头31与感光元件32之间的第一距离D1(图4示)可以更小，进而镜头模组30的厚度可以更小，从而终端100可以制作的更薄。
在一个例子中，装饰盖板21可设有滤光层，使得装饰盖板21可以具有滤光效果。例如可以在装饰盖板21靠近镜头31的表面、和\或装饰盖板21远离镜头31的表面通过镀膜工艺增设滤光层，或者通过其他工艺在装饰盖板21的中间区域设置滤光层。
在另一个例子中，镜头31可包括多个镜片，例如镜头31可以包括2个、3个、4个、5个、6个、7个、8个或更多个镜片，至少一个镜片可以设有滤光层，使得镜头31可以具有滤光效果。例如可以在一个镜片的表面、或多个镜片的表面、或每个镜片的表面，通过镀膜工艺镀滤光层。
在又一个例子中，装饰盖板21可设有第一滤光层，且镜头31的至少一个镜片设有第二滤光层，使得装饰盖板21可以实现对入射光进行第一次过滤，镜头31可以对穿过装饰盖板21的入射光进行第二次过滤，进而镜头模组30实现了较好的成像效果。
请参阅图14及图19，镜头模组30还可包括电路板36，感光元件32可以安装于电路板36，电路板36可以为感光元件32提供电源，使得感光元件32可以将接收到的光信号转换成电信号并生成图像数据。支架33可以安装在电路板36上，第二驱动部件34和电路板36可以分别位于支架33的相背两侧，电路板36可以与第二驱动部件34中的线圈3431连接，以给线圈3431通电。
请参阅图14及图21，在某些实施方式中，镜头模组30还可包括间隔件37，间隔件37设置于感光元件32与镜头31之间，间隔件37可以部分罩设感光元件32，间隔件37能够使感光元件32与镜头31之间具有预设厚度(即间隔件37的厚度)的间隙。具体地，间隔件37可以环绕感光元件32的边缘设置，或者间隔件37可以设置在感光元件32的相对的两侧，间隔件37的厚度可以为预设厚度，镜头31朝感光元件32运动时，间隔件37可以抵持镜头31，使得镜头31不会与感光元件32接触，进而感光元件32不易被镜头31损坏。其中，间隔件37可以由塑料、硅胶等材料制成。
请一并参阅图1、图4至图6及图22，本申请还提供了一种终端100的控制方法，控制方法可以应用于上述任一实施方式的终端100中。控制方法包括以下步骤：
01：接收到进入第三状态的指令时，控制装饰盖板21朝远离感光元件32的方向运动第一预定距离；
02：预定时长后控制镜头31朝远离感光元件32的方向运动第二预定距离；和
03：控制镜头模组30获取图像数据。
本申请实施方式的控制方法中，在接收到进入第三状态的指令时，首先控制装饰盖板21朝远离感光元件32的方向运动第一预定距离，在预定时长后才控制镜头31朝远离感光元件32的方向运动第二预定距离，然后才控制镜头模组30获取图像数据，由此，在镜头模组30进入第三状态的过程中，镜头31和装饰盖板21运动不易产生干涉，使得装饰盖板21不易与镜头31发生碰撞，同时由于装饰盖板21和镜头31均可朝远离感光元件32的方向运动，则装饰盖板21和镜头31之间的距离在平时(不拍照)时可压缩到最小，甚至为零进而可以减少镜头模组30和装饰部件20的组合厚度，使得终端100可以制造的较薄。
具体地，如上述实施例所述，镜头模组30可包括第一状态、第二状态和第三状态，在不需要使用镜头模组30时，镜头模组30可处于第一状态。在需要使用镜头模组30时，镜头模组30可处于第二状态和第三状态。镜头模组30由第一状态进入第三状态，首先需要由第一状态进入第二状态，然后由第二状态进入第三状态。进入第三状态的指令可以是由用户在终端100的操作触发，例如用户点击了终端100的相机图标、用户和他人开始视频等需要镜头模组30工作的操作可以触发进入第三状态的指令。
在触发进入第三状态的指令后，相关的应用可以将进入第三状态的指令发送至处理器。然后处理器可以控制第一驱动部件40驱动装饰盖板21朝远离感光元件32的方向运动第一预定距离，使得装饰盖板21与感光元件32之间的距离可以增大至第三距离D3或第五距离D5。其中，可以是在装饰盖板21开始运动后预定时长控制镜头31朝远离感光元件32的方向运动第二预定距离，也可以是装饰盖板21运动第一预定距离后预定时长控制镜头31朝远离感光元件32的方向运动第二预定距离。其中，预定时长可以是固定时长，例如30毫秒、50毫秒、80毫秒、100毫秒、150毫秒、200毫秒等固定时长。
由于在第一状态时镜头31和装饰盖板21之间的距离接近于0或者为0，接收到进入第三状态的指令时，装饰盖板21先运动使得镜头31和装饰盖板21之间具有一定的安全距离，从而镜头31运动不易与装饰盖板21发生碰撞，提升了终端100的安全性。
在镜头31运动第二预定距离后，控制镜头模组30获取图像数据。可以理解，在镜头31运动第二预定距离后，镜头模组30已经完成了调焦，如此，镜头模组30可以具有较好地成像效果。
进一步地，请结合图23，在某些实施方式中，控制方法还可包括以下步骤：
04：在镜头31朝远离感光元件32的方向运动至第二预定距离的过程中，控制感光元件32进行初始化。
具体地，在步骤02进行过程中，可以同步执行步骤04，相对于在镜头31运动第二预定距离后才执行步骤04，可以减短镜头模组30的响应时长，减少终端100的黑屏时间，提高了用户的使用体验。例如，在镜头31开始朝远离感光元件32的方向运动时，可以给感光元件32通电以使感光元件32可进行初始化。
请结合图24，在某些实施方式中，控制方法还可包括以下步骤：
05：当镜头31朝远离感光元件32的方向运动至第三预定距离时，控制镜头模组30获取预览图像，第三预定距离小于第二预定距离。
具体地，在镜头31朝远离感光元件32的运动至第三预定距离时，则控制镜头模组30获取预览图像，此时镜头31还未运动至第二预定距离，在镜头31运动第二预定距离时，控制镜头模组30获取图像数据，此时的图像数据为正式图像数据，相较于镜头31运动至第二预定距离时镜头模组30才开始获取预览图像或者图像数据而言，可以减少终端100在进入第三状态过程中的黑屏时间，提升用户的使用体验。进一步地，在镜头31朝远离感光元件32的方向运动至第三预定距离的过程中，可以控制感光元件32进行初始化，以进一步减少终端100进入第三状态的黑屏时间。
请结合图25，在某些实施方式中，终端100还可包括辅助镜头模组(未图示)，控制方法还可包括以下步骤：
06：在装饰盖板21朝远离感光元件32的方向运动第一预定距离的过程中，控制辅助镜头模组 30获取预览图像；及
07：在镜头31朝远离感光元件32的方向运动第二预定距离后，切换至镜头模组30获取预览图像及图像数据。
具体地，辅助镜头模组可以用于辅助成像，辅助镜头模组的像素可低于镜头模组30的像素。为了避免在进入第三状态时，镜头模组30需较长时间响应而导致终端100的黑屏时间较长，在装饰盖板21运动朝远离感光元件32的方向运动第一预定距离的过程中，可以控制辅助镜头模组获取预览图像，使得在装饰盖板21运动过程中终端100可通过辅助摄像模组成像，终端100的黑屏时间较短，终端100可以较快地响应，进而可提升用户的使用体验。在镜头31朝远离感光元件32的方向运动第二预定距离后，切换至镜头模组30获取预览图像及图像数据，以提升终端100正式成像的清晰度。
