技术领域
本申请属于电子设备技术领域，具体涉及一种摄像头模组及电子设备。
背景技术
目前移动终端行业内，多数移动终端配置的摄像头模组设置有自动变焦摄像头，以驱动电机带动摄像头模组中的导向柱运动以使多个镜片的距离发生变化进而实现变焦功能。
在用户使用摄像头变焦功能的同时，可能会出现手机发生跌落或遭到碰撞的情况，该种情况会导致摄像头模组中的导向柱受到不同程度的损伤，可能导致导向柱无法正常滑动，而导向柱无法正常滑动意味着镜头无法正常伸缩，使摄像头模组的变焦摄像功能无法使用。
发明内容

第一方面，本申请实施例提供了一种摄像头模组，包括第一支架、镜片组件，所述第一支架套设于所述镜片组件外围；所述第一支架上设置有导轨槽，所述镜片组件上设置有导向柱；所述导向柱可移动的设于所述导轨槽内；所述导轨槽包括第一部分、第二部分和第三部分，所述第三部分的坡度比所述第一部分的坡度平缓，所述第二部分连接于所述第一部分和所述第三部分之间；所述导轨槽与导向柱之间设置有弹性件，所述导向柱从所述第三部分向所述第一部分移动时，所述弹性件发生形变。
第二方面，本申请实施例提供了一种电子设备，包括如前所述的摄像头模组。
在本申请实施例中，第一支架的设置用于为镜片组件提供支撑，导轨槽的设置用于为镜片组件的运动提供轨道，导向柱的设置用于与导轨槽配合并在导轨槽内滑动以实现镜片组件的伸缩。导轨槽上设置有多个部分，包括第一部分、第二部分和第三部分，导轨槽上还具有多处坡度变化，第三部分的坡度比第一部分的坡度平缓，第二部分的设置用于连接第一部分和第三部分。导轨槽上设置有弹性件，弹性件处于导轨槽和导向柱之间，当导向柱由第三部分向第一部分移动时，弹性件受到力的作用而发生形变，由于弹性件发生形变，当导向柱移动到弹性件发生形变的位置处时，导向柱与弹性件之间可能发生微小碰撞或不发生碰撞，导向柱沿弹性件更容易滑落，镜片组件随导向柱的滑落而缩回，从而降低导向柱受到的冲击力，降低导向柱与导轨槽碰撞导致镜片组件破裂失效风险的有益效果。

下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的摄像头模组及电子设备进行详细地说明。
如图1所示，镜片组件20由包括套筒22在内的多个结构构成，包括：镜片、镜头支架、滑动支架和导轨支架等，镜片组件20用于实现镜头伸缩的功能，在一定范围内通过变换焦距实现远景和近景变化。
如图2所示，在机械补偿变焦距光学系统中，通过设置符合光学变焦拟合曲线的轨道，与沿轨道的移动来带动摄像头伸缩，实现摄像头变焦的目的。其中，若干个变焦点之间的曲线并不相同，例如，4x－2x(4倍－2倍变焦)光学变焦范围对应的导轨槽11较为平缓，4x－5x(4倍－5倍变焦)的导轨为突变区域。
参见图3至图18，本申请的实施例提供了一种摄像头模组，包括：第一支架10、镜片组件20，所述第一支架10套设于所述镜片组件20外围；
所述第一支架10上设置有导轨槽11，所述镜片组件20上设置有导向柱21；所述导向柱21可移动的设于所述导轨槽11内。
所述导轨槽11包括第一部分112、第二部分113和第三部分114，所述第三部分114的坡度比所述第一部分112的坡度平缓，所述第二部分113连接于所述第一部分112和所述第三部分114之间。
所述导轨槽11与导向柱21之间设置有弹性件111，所述导向柱21从所述第三部分114向所述第一部分112移动时，所述弹性件111发生形变。
在本申请实施例中，第一支架10的设置用于为镜片组件20提供支撑，导轨槽11的设置用于为镜片组件20的运动提供轨道，导向柱21的设置用于与导轨槽11配合并在导轨槽11内滑动以实现镜片组件20的伸缩。如图3所示，导轨槽11上设置有多个部分，包括第一部分112、第二部分113和第三部分114。导轨槽11上还具有多处坡度变化，第三部分114的坡度比第一部分112的坡度平缓，第二部分113的设置用于连接第一部分112和第三部分114。导轨槽11上设置有弹性件111，弹性件111处于导轨槽11和导向柱21之间。如图4所示，导向柱21能够控制镜头组件20的伸缩，当导向柱21由第三部分114向114第一部分112移动时，弹性件111受到力的作用而发生形变，由于弹性件111发生形变，当导向柱21移动到弹性件111发生形变的位置处时，导向柱21与弹性件111之间可能发生微小碰撞或不发生碰撞，导向柱21沿弹性件111自然滑落，镜片组件20随导向柱21的 滑落而缩回。在摄像头组件遭受外力或撞击时，本申请的实施例具有降低导向柱21与导轨槽11碰撞导致镜片组件20破裂失效风险的有益效果。
需要说明的是，上述微小碰撞指导向柱21不发生损伤且能沿弹性件111顺利滑落的碰撞。
还需要说明的是，第一支架10上可以设置有多个导轨槽11。例如，第一支架10上可以设置有2个导轨槽11，第一支架10上也可以设置有3个导轨槽11，本实施例对此不作任何限定。相应的，在镜片组件20上可以设置与导轨槽11数量对应个数的导向柱21，导向柱21伸入对应的导轨槽11，然后配合滑动。
可选地，在本申请实施例中，所述第二部分113设置有所述弹性件111，所述导向柱21从所述第三部分114向所述第一部分112移动时，所述弹性件111的坡度变缓
在本申请实施例中，弹性件111设置于第二部分113，当导向柱21由第三部分114向第一部分112移动并经过第二部分113时，设置于第二部分113的弹性件111受到力的作用而发生形变，由于弹性件111发生形变，当导向柱21移动到第二部分113的位置处时，导向柱21与弹性件111之间可能发生微小碰撞或不发生碰撞，导向柱21沿弹性件111从第二部分113处自然滑落，镜片组件20随导向柱21的滑落而缩回。本申请的实施例通过将弹性件111设置在第二部分113，当摄像头组件遭受外力或跌落等撞击时，导向柱21从第三部分114向第一部分112移动并经过第二部分113时，弹性件111产生的形变使弹性件111的坡度变缓，在一定程度上避免了与导向柱21之间的碰撞，为导向柱21沿弹性件111的自然滑落提供了空间位置，更有利于导向柱21顺利通过第二部分113的坡度变化区域而滑落至第一部分112，从而避免导向柱21卡在第二部分113无法下滑带来的卡顿甚至是折损。
可以理解的是，在导向柱21从第三部分114向第一部分112移动的情况下，摄像头模组遭受外力或跌落等撞击时，摄像头模组处于受到外力或跌落的状态；摄像头模组未受到外力或跌落等撞击时，摄像头模组处于正常工作的状态。根据摄像头模组的不同状态，对应于摄像头模组的不同状 态，弹性件111也具有不同的状态，包括压缩状态和自然状态。
在本实施例中，当摄像头模组处于正常工作状态下的情况时，导向柱21根据用户需要在第一部分112和第三部分114之间移动以实现摄像头的调焦。在工作状态下，第二部分113的弹性件111具有坡度突变区域，即第二部分113表面的弹性件111中靠近第一部分112的缓冲部111a的坡度大于靠近第三部分114的平缓部111b的坡度，可有效防止导向柱21在调焦过程中抖动或滑落。当摄像头模组处于受到外力或跌落状态的情况时，导向柱21由第三部分114向第一部分112运动的过程中，弹性件111的缓冲部111a在导向柱21所承受的外力冲击下被压缩变形从而使缓冲部111a坡度较缓，有利于导向柱21顺利滑落，避免导向柱折损。
在摄像头模组处于受力或跌落状态的情况下，弹性件111受到来自导向柱21的力而变形，使得弹性件111在导轨槽11的突变区域的坡度变缓。自然状态指弹性件111未受到来自导向柱21的力时，弹性件111坡度变陡。摄像头模组处于正常工作的状态，用户可根据需要在第一部分112和第三部分114之间来回移动导向柱21以实现摄像头的调焦，自然状态的弹性件111在第二部分113通过缓冲部111a和平缓部111b的坡度落差形成坡度突变区域以有效防止导向柱21在调焦过程中抖动或滑落至第一部分112。当镜片组件20需要复位至第一部分112起始位置时，镜片组件20由伸出状态向缩回方向切换，导向柱21受到指向缩回方向的力以通过坡度突变区域，导向柱21挤压弹性件111使弹性件111从自然状态向形变状态切换，弹性件111在第二部分113的坡度变缓，导向柱21自然滑落，镜片组件20缩回。如图8所示，当镜片组件20由伸出状态向缩回方向切换的同时，且导向柱21受到指向缩回方向的力时，弹性件111处于压缩状态，在压缩状态下的弹性件111发生形变，导轨槽11的突变区域坡度变缓。该种方式可以使用弹性件111自身的弹性为导向柱21提供缓冲，结构简单，维护方便。
可选地，参照图3，所述弹性件111设置在所述导轨槽11的表面，所述弹性件111在所述导轨槽11上的正投影覆盖所述第一部分112、所述第二部分113和所述第三部分114，所述导向柱21从所述第三部分114向所述第一部分112移动时所述弹性件111的坡度变缓。
在本申请实施例中，弹性件111设置于导轨槽11的表面，其中，弹性件111在导轨槽11上的正投影完全覆盖第二部分113的表面，并且弹性件111在导轨槽11上的正投影至少部分地覆盖第一部分112的表面以及至少部分地覆盖第三部分114的表面。当导向柱21从第三部分114向第一部分112移动时，弹性件111发生弹性形变，弹性件111的坡度变缓，导向柱21沿弹性件111自然滑落。本申请的实施例具有增强导向柱21自然滑落平稳性的有益效果。
需要说明的是，弹性件111在导轨槽11上的正投影也可以完全覆盖第一部分112、第二部分113和第三部分114，本实施例对此不作任何限定。
可选地，参照图6和图7，在本申请实施例中，所述弹性件111为弹片，所述弹片的两端设置有凸耳1111，所述第一支架10上还设置有活动槽13，所述活动槽13设置于所述导轨槽11两端，所述凸耳1111通过所述活动槽13与所述第一支架10活动连接。
当所述弹片发生弹性形变时，所述凸耳1111在所述活动槽13内活动。
在本申请实施例中，弹性件111可以是弹片，弹片的两端设置有凸耳1111结构1111，凸耳1111的设置用于将弹片连接于第一支架10上，第一支架10上还设置有活动槽13，活动槽13设置于导轨槽11的两端，凸耳1111和活动槽13活动连接，活动槽13的设置为凸耳1111提供了一定的活动空间，弹片通过凸耳1111与活动槽13活动连接，凸耳1111至少部分的处于活动槽13内，凸耳1111能够在槽内移动。当弹片未发生弹性形变时，凸耳1111与活动槽13中靠近导轨槽11的一侧抵接，当弹片发生弹性形变时，凸耳1111与活动槽13中靠近导轨槽11的一侧分离，并朝远离导轨槽11的方向移动。本申请的实施例通过在弹片上设置凸耳1111以及在第一支架10上设置与凸耳1111相对应的活动槽13，通过活动槽13实现对弹片的限位作用，以及通过设置活动槽13为凸耳1111的移动提供空间位置，具有防止弹片回缩和为弹片形变提供移动空间的有益效果。
可选地，所述弹性件111为弹片，所述弹性件111的两端固定在所述第二部分113的两端，所述弹片与所述第二部分113之间预留有形变空间，所述弹片的两端分别与所述第一部分112和所述第三部分114固定连接。
可选的，所述弹性件111为弹片，弹片的一端与第一部分112固定连接，弹片的另一端与第三部分114固定连接。弹片的两端与导轨槽11固定，弹片与第二部分113之间预留有形变空间，形变空间的设置用于为弹片的形变提供空间。当弹片发生形变时，弹片的两端固定不动，第二部分113上的弹片向靠近导轨槽11表面的方向运动以压缩形变空间；当弹片恢复形变时，弹片的两端固定不动，第二部分113上的弹片向远离导轨槽11表面的方向运动以增大形变空间。
可选地，参照图3、图9和图10，在本申请实施例中，所述弹性件111设置在所述导轨槽11的表面，设置在所述第二部分113表面的弹性件111包括缓冲部111a和平缓部111b，所述缓冲部111a靠近所述第一部分112，所述平缓部111b靠近所述第三部分114，所述缓冲部111a的坡度大于所述平缓部111b的坡度，靠近所述第一部分112的所述缓冲部111a坡度变陡。
所述摄像头模组还包括凸轮30，所述凸轮30包括第一曲率部31；在所述第一曲率部31与所述弹性件111抵接时，所述弹性件111在所述第二部分113向所述导轨槽11内侧形变；在所述第一曲率部31与所述弹性件111脱离时，所述弹性件111向自然状态恢复。
在本申请实施例中，导轨槽11第二部分113的坡度相对于第一部分112的坡度和第二部分113的坡度发生了突变，设置在第二部分113表面的弹性件111包括缓冲部111a和平缓部111b，其中，缓冲部111a靠近第一部分112，平缓部111b靠近第三部分114，缓冲部111a和平缓部111b的设置用于与导轨槽11第二部分113的坡度相适配，以使弹性件111的形状与第二部分113的形状匹配。在一种实施例中，当摄像头模组处于正常工作状态下的情况时，第一曲率部31与第二部分113抵接，导向柱21由第三部分114向第一分部112运动的过程中，弹性件111处于自然状态坡度较陡，导向柱21沿自然状态下的弹性件111运动。在另一种实施例中，当摄像头模组处于受到外力或跌落状态的情况时，第一曲率部31与第二部分113分离，此时，弹性件111的坡度相对于第一曲率部31与第二部分113抵接时的坡度变缓，导向柱21由第三部分114向第一分部112运动的过程中，弹性件111坡度较缓，导向柱21沿弹性件111运动，在上述运动过程中，由于弹性件111坡度变缓，有利于导向柱21顺利滑落，避免导向柱折损。当摄像头组 件遭受外力或跌落等撞击时，导向柱21从第三部分114向第一部分112移动并经过第二部分113时，弹性件111的缓冲部111a和平缓部111b产生的形变使弹性件111的坡度变缓，平缓部111b和缓冲部111a的设置更有利于导向柱21顺利通过第二部分113的坡度变化区域而滑落至第一部分112，从而避免导向柱21卡在第二部分113无法下滑带来的卡顿甚至是折损的有益效果。
可选地，如图11和图12，在本申请实施例中，所述摄像头模组还包括凸轮，所述凸轮30包括第一曲率部31和第二曲率部32；在所述第一曲率部31与所述弹性件111抵接时，所述弹性件111的坡度变陡；在所述第二曲率部32与所述弹性件111抵接时，所述弹性件111的坡度变缓。

在本申请实施例中，凸轮30可以为只有一部分扇面，在凸轮30所旋转的整个圆周中，其他部分没有扇面，该扇面为第一曲率部31。在第一曲率部31转动至与弹性件111抵接时，使弹性件111在导轨槽11的第二部分113的坡度符合摄像头模组正常工作状态下的坡度。在凸轮30的第一曲率部31与弹性件111脱离后，由于没有其他部件与弹性件111抵接，则弹性件111向自然状态进行恢复，使弹性件111在第二部分113的坡度变缓，上述方式凸轮30用料更节约，凸轮30制造成本更低。
在本申请实施例中，在凸轮30包括第一曲率部31的基础上，还包括第二曲率部32。当凸轮30转动使得第二曲率部32与弹性件111抵接时，弹性件111在导轨槽11第二部分113的坡度变缓，使得导向柱21自然滑落，镜片组件20缩回，在本申请的实施例中，第二曲率部32的设置实现了弹性件 111在导轨槽11的第二部分113的坡度变缓，第二部分113的坡度变缓具有能够使得导向柱21自然滑落的有益效果。

需要说明的是，在实际应用中，移动终端的传感器40将传感器40信号发送给处理器50，处理器50根据传感器40信号确定出移动终端处于受外力或坠落状态后，向驱动件60发送转动信号，驱动件60带动凸轮30转动直至凸轮30的第一曲率部31与弹性件111脱离接触。处理器50根据传感器40信号确定出移动终端未处于受外力或坠落状态，也可以向驱动件60发送转动信号，驱动件60带动凸轮30转动直至凸轮30的第一曲率部31与弹性件111抵接。其中，驱动件60可以是驱动电机。当摄像头模组所在的电子设备的陀螺仪检测出电子设备的运动加速度a≈G(重力加速度9.8m/s 2)时，导向柱21从第三部分114向第一部分112移动，驱动件60在跌落过程中快速控制凸轮30旋转，使第二曲率部32与弹性件111抵接；当电子设备的陀螺仪没有检测出电子设备的运动加速度a≈G(重力加速度9.8m/s 2)时，或者，导向柱21从第一部分112向第三部分114移动时，驱动件60控制凸轮 30的第一曲率部31转动至与弹性件111抵接的位置。
还需要说明的是，在摄像头模组遭受外力或跌落等撞击时，陀螺仪可以根据摄像头模组所在的电子设备的运动加速度a≈G(重力加速度9.8m/s 2)检测到摄像头模组所在的电子设备处于跌落的状态，处理器50能够在电子设备发生跌落时对驱动件60发出指令带动凸轮30旋转，响应于传感器40的指令信号，驱动件60在第一时间带动凸轮30旋转，驱动件60的快速响应能够使得凸轮30的第二曲率部32在电子设备还未跌落完成时已经与弹性件111抵接，能够提前预防跌落造成的损坏，避免导向柱21折损。
可选地，在本申请实施例中，所述第一支架10内在对应所述第二部分113的位置设置有容纳腔12，所述容纳腔12朝向所述第二部分113的方向设置有开口；
所述凸轮30设置于所述容纳腔12内，所述凸轮30在所述容纳腔12内转动使所述第一曲率部31或所述第二曲率部32通过所述开口与所述弹性件111抵接。
在本申请实施例中，该容纳腔12开设在导轨槽11安装弹性件111的一侧，或者说设置在第二部分113凸起方向的相反方向，然后与导轨槽11邻接。容纳腔12的设置用于为凸轮30的设置提供容纳空间，容纳腔12设置于第一支架10上，容纳腔12的一侧设置有开口，开口朝向第二部分113所在的位置处，凸轮30嵌设于容纳腔12内，凸轮30能够在容纳腔12内自由转动，在凸轮30的转动过程中第一曲率部31或第二曲率部32能够通过开口与弹性件111的第二部分113抵接，本申请的实施例通过设置容纳腔12为凸轮30提供设置安装空间，具有节约空间，减小摄像头模组体积，实现摄像头模组小型化的有益效果。
可选地，如图13，在本申请实施例中，所述弹性件111与所述导轨槽11之间设置有缓冲介质层1112。
在本申请实施例中，缓冲介质层1112的设置用于吸收从弹性件111方向传递来的冲击力，减轻导向柱21与弹性件111之间因碰撞产生的损伤，防止因导向柱21破损而导致的摄像头模组损坏。
需要说明的是，缓冲介质层1112的厚度范围是0.05mm￣0.2mm。
还需要说明的是，在弹性件111面向导向柱21的一侧也设置有缓冲介质层1112，能够进一步减轻导向柱21与弹性件111之间因碰撞产生的损伤。需要说明的是，缓冲介质层1112的材质可以是橡胶、海绵等，橡胶层和海绵层的设置用于缓释一定量的来自弹性111件的外力，有助于吸收外力作用并且为导向柱21和弹性件111之间的碰撞提供一定的缓冲作用，减少导向柱21与弹性件111之间的碰撞冲击。
还需要说明的是，弹性件111可以是弹性钢片、弹性塑料片等，弹簧钢片和弹性塑料片具有一定的屈服强度，在承受重载荷时不引起塑性变形而仅发生一定的弹性形变，并有足够的韧性和塑性，以防在力的作用下突然脆断。
可选地，在本申请实施例中，所述导轨槽11内侧可以设置一体成型的弹性件111，所述弹性件111与所述导轨槽11的形状相适配。
在本申请实施例中，导轨槽11的内侧可设置为整体弹性件111，弹性件111的形状与导轨槽11内壁形状相适配，导轨槽11和弹性件111可以为一体成型结构。
可选地，在本申请实施例中，如图14和图15，所述弹性件111为弹片，所述弹片上设置有通孔1113，所述缓冲介质层1112通过所述通孔1113与所述弹片嵌合。
在本申请实施例中，通孔1113的设置用于与缓冲介质层1112连接，缓冲介质层1112可注塑至弹性件111靠近导向柱21的一侧及弹性件111的通孔1113内部，使得缓冲介质层1112与弹性件111的结合度更强，本申请的实施例具有增强缓冲介质层1112与弹片之间连接强度的有益效果
需要说明的是，该弹片可以为弹簧钢片和弹性塑料片中的至少一种，弹簧钢片和弹性塑料片具有一定的屈服强度，在承受重载荷时不引起塑性变形而仅发生一定的弹性形变，并有足够的韧性和塑性，以防在力的作用下突然脆断。
可选地，在本申请实施例中，结合图3和图16，所述缓冲介质层1112对应于所述第二部分113的厚度大于所述缓冲介质层1112对应于所述第一部分112的厚度；所述缓冲介质层1112对应于所述第二部分113的厚度大 于所述缓冲介质层1112对应于所述第三部分114的厚度。
需要说明的是，在实际使用中，缓冲介质层1112可以使用橡胶层，当然还可以使用其他缓冲物质，比如海绵等。该缓冲介质层1112在第二部分113的厚度大于在其他部分的厚度。在实际应用中，在第二部分113的该缓冲介质层1112，其靠近第一部分112和第三部分114位置的厚度小于第二部分113中部位置的厚度，从第二部分113的弯折度最大的位置分别向第一部分112方向和第三部分114方向，其厚度从厚逐渐变薄。
在本申请实施例中，缓冲介质层1112对应于导轨槽11不同部分的厚度不同，由于弹性件111的有效形变集中在第二部分113，因此，缓冲介质层1112对应于第二部分113的厚度相对第一部分112和第三部分114较厚，在导向柱21由第三部分114向第一部分112运动的过程中，第二部分113的缓冲区113a坡度大于平缓区113b的坡度，移动到第二部分113对应的缓冲介质层1112处的导向柱21会受到阻挡，因此，在第二部分113对应的缓冲介质层1112处设置的厚度较厚有利于导向柱21的顺利滑落，具有防止因导向柱21在滑落过程中受到阻挡产生碰撞破损而导致的摄像头模组损坏的有益效果。
需要说明的是，缓冲介质层1112对应于第一部分112和第三部分114的厚度可以相同，也可以不同，本实施例对此不作任何限定。
可选地，在本申请实施例中提供了一种电子设备，包括如前所述的摄像头模组。
在本申请实施例中，电子设备可以是电脑、平板电脑、手机或电话手表中任意一者。
