Description

镜头限位组件、相机的机身及相机模块 技术领域
本发明涉及镜头限位组件，以及涉及具有镜头限位组件的相机的机身及相机模块。
背景技术
相机包含镜头和机身，镜头与机身固定或者可拆卸连接。要保证成像稳定，需要保证镜头到影像传感器的法兰距要尽量精确，这样成像才会稳定清晰。现有的相机镜头的装配方式是将镜头旋转安装到相机的机身上，靠机身上的镜头装配圈勾住，然后在镜头装配圈处增加一个镜头释放按钮组件，插入镜头里，防止镜头脱落。
上述方式中，镜头既然能旋转，通常至少有0.05mm左右的间隙，然而若相机用在有振动的平台上，将会导致后面的触点和相机镜头接触不是很好，甚至失效，另外镜头也可能因间隙而使法兰距微微变化。有设计者提出使用弹簧片消除上述间隙，然而弹簧片不够稳定，无法保证紧密配合程度。

该镜头装配圈20朝向该弹性元件10的端面设置有第二定位孔28，该第二定位孔28为盲孔，用于与该第一定位孔14对应并通过相机的机身的一个定位销串接。该镜头装配圈20还设有贯穿其两相对端面，并用于与相机的机身的其它部件配合的1个配合孔29，以及用于与相机的机身固定的4个螺栓孔291。该镜头装配圈20的内壁延伸出3个相互间隔的限位部22，且该镜头装配圈20朝向该弹性元件10的端面设有3个相互间隔的收容槽27。每个该收容槽27的一侧设置有一第一斜面24。本实施例中，该收容槽27的底面为平面，该第一斜面24由该底面向外延伸形成，且沿该镜头装配圈20的圆周方向倾斜。而该限位部22为设置于该镜头装配圈20的内侧的凸肋。每个该限位部22的左右两侧是平滑的表面26，可以直接为该镜头装配圈20的内壁面或向内开设的滑槽面。
该锁紧圈30的外侧设有防滑槽38，内侧设有3个相互间隔的挂钩32。本实施例中，每个该挂钩32大致呈L形从该锁紧圈30的内壁延伸出，每个该挂钩32具有与该锁紧圈30的内壁连接的连接部321，和与该连接部321连接的弯折部322。每个该弯折部322的一个表面的端部设有一个相对该表面其它部位倾斜的第二斜面34，每个该弯折部322与上述表面相对的另一表面是平面36。该第二斜面34与该第一斜面24相匹配，每个该挂钩32收容在一个对应的该收容槽27，该第二斜面34抵持该第一斜面24，该平面36用于抵持该弹性元件10的弹性臂12。
当外侧具有3个相互间隔的卡持部的镜头（见图5）准备装配入该镜头装配圈20，该卡持部自该镜头装配圈20的平滑表面26处滑入该镜头装配圈20，接下来可以通过旋转该镜头使卡持部旋转至该限位部22及弹性元件10的自由臂12下方，然后使用者沿一方向可以旋转该锁紧圈30，该挂钩32的第二斜面34在该第一斜面24上运动且随该第一斜面24高度的增加而压迫该弹性元件10，该弹性元件的自由臂12会压迫该镜头的卡持部向相机的机身方向，即锁紧镜头。当沿相反方向旋转该锁紧圈30时，该挂钩32的第二斜面34在该第一斜面24上反向运动且随该第一斜面24高度的减小而释放该弹性元件10，从而镜头可以旋转出来。
请一并参阅图4和图5，本发明实施例提供的相机的机身200包括固定框210，该固定框210具有镜头装配口212，用于装配外侧设有卡持部的镜头，该镜头装配口212设置有该镜头限位组件100。该固定框210还凸出有1个定位销221、4个螺栓222和设置有可伸缩的限位结构150，该弹性元件10通过该卡口16与该可伸缩的限位结构150的圆形螺母151嵌套卡合。该镜头装配圈20与该锁紧圈30配合好而设置在该弹性元件10上，该定位销221穿过该弹性元件10的第一定位孔14，并伸入该镜头装配圈20的第二定位孔28而串接该弹性元件10与该镜头装配圈20；该4个螺栓222伸入该镜头装配圈20的4个螺栓孔291而固定该镜头装配圈20；该可伸缩的限位结构150的凸柱152伸出该镜头装配圈20的配合孔29，并可沿该凸柱152凸出的方向伸缩，与和镜头定位；该锁紧圈30可转动地设置在该镜头装配圈20外围。
请一并参阅图6至图8，本发明实施例提供的相机模块300包括镜头310和机身200。该镜头310具有镜筒312，该镜筒312具有一装配部313，该装配部313的外壁设有3个相互间隔的卡持部314，本实施例中，该卡持部314为凸缘。当该镜头310准备装配入该镜头装配圈20，该卡持部314自该镜头装配圈20的平滑表面26处滑入该镜头装配圈20，接下来可以通过旋转该镜头310使卡持部314旋转至该弹性元件10的自由臂12下方，然后沿一方向可以旋转该锁紧圈30，该挂钩32的第二斜面34在该第一斜面24上运动且随该第一斜面24相对该收容槽27的底面相垂直方向上的高度的增加而压迫该弹性元件10，该弹性元件10的自由臂12会压迫该镜头310的卡持部314向机身200方向，即锁紧镜头310于机身200上。当沿相反方向旋转该锁紧圈30，该挂钩32的第二斜面34在该第一斜面24上反向运动且随该第一斜面24高度的减小而释放该弹性元件10，从而镜头310可以从机身200旋转出来。
该机身200内设置有触点220，用于当镜头310紧固装配时与镜头310内的驱动器等电性连接。
可以理解的是，所述挂钩32的形状不一定如上述实施例的图中所示，而仅需能够在第一斜面24与弹性元件10之间稳定滑动即可。
在其它实施例中，所述镜头装配圈20不一定通过螺栓孔与相机的机身的螺栓固定的方式，而可以采用粘胶等方式固定。
综上，本发明实施例提供的镜头限位组件设有锁紧圈，在拧锁紧圈时，弹性元件受到压迫，从而压紧镜头的卡持部，从而锁紧镜头，防止镜头旋转及轴向脱落。本发明实施例提供的相机的机身和相机，由于有所述镜头限位组件，镜头与机身可以锁紧，防止镜头旋转及轴向脱落。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
