以下结合本说明书的附图，对本公开的较佳实施方式予以进一步地详尽阐述。
本公开提出一种柔光箱(图未示)及其卡盘组件。卡盘组件用于将摄像装置(图未示)固定连接于柔光箱上，方便摄像装置的拍摄使用。
请参阅图1及图2，具体在本实施方式中，柔光箱包括卡盘组件10、伞骨20及柔光布(图未示)。柔光布可拆卸设于伞骨20上。伞骨20的一端铰接于卡盘组件10上。伞骨20相对于卡盘组件10可呈伞状打开和收折，实现柔光箱的打开与收起。其中，图1为伞骨20处于收折状态图示，图2为伞骨20处于打开状态的图示。
请同时参阅图3，卡盘组件10包括卡口11、卡盘12及旋转盘13。卡口11及旋转盘13均设置于卡盘12上。卡口11用于连接摄像装置或光源。旋转盘13相对于卡盘12转动，驱动伞骨20打开和收折。
伞骨20为一狭长形用于支撑柔光布的支撑杆。伞骨20靠近卡盘12的一端为铰接端 21。该铰接端21设有铰接套22。铰接套22的外侧面设有弧形的压持面23。压持面23的表面为弧形面。弧形面有助于压持铰接端21带动伞骨20运动。铰接套22的相对两侧设有枢轴24。铰接端21以枢轴24为轴进行转动。
请同时参阅图4，卡盘12包括承载环121及套管122。承载环121设于套管122的外侧。卡盘12可以为注塑件。承载环121与套管122可以为一体成型。套管122的中心轴即为摄像装置的光轴方向。
承载环121背向旋转盘13的一侧设有漫反射层120。该漫反射层120可以将光源光线进行漫反射，以保证柔光箱内的光线柔和。漫反射层120设有可形成漫反射的纹路。具体在本实施方式中，该纹路可以为阶梯状纹路。
承载环121用于承载多个与之铰接连接的伞骨20。承载环121设有支撑面。支撑面上设有用于铰接伞骨20的铰接部123。铰接部123凸出于环形的支撑面。并且，铰接部123沿环形的支撑面的周向均匀分布。具体地，铰接部123开设有用于收容伞骨20的枢轴24的轴槽124。该枢轴24可以分别收容于铰接部123的轴槽124内，与铰接部123形成铰接连接。
并且，铰接部123具有一定高度，则轴槽124也具有一定高度。当伞骨20的枢轴24在轴槽124内转动的同时，其枢轴24也沿轴槽124的延伸方向上下运动。一方面，可以方便伞骨20相对于承载环121摆动，另一方面，当伞骨20完全打开的时候，伞骨20的铰接端21的外侧面可以抵持于支撑面上，保证伞骨20能够稳定地处于打开状态。
套管122设于承载环121的内侧。套管122的内侧设有台阶部125。该台阶部125供卡口11连接。具体地，卡口11设有凸沿111。请参阅图5，该凸沿111可以通过螺钉30与台阶部125固定连接，实现卡口11与卡盘12可拆卸连接。当卡口11的类型需要更换的时候，需要拆卸螺钉30即可。在其他实施方式中，卡口11还可以通过卡合连接的方式与卡盘12实现可拆卸连接。
请再次参阅图3，具体在本实施方式中，卡口11为外侧设有供摄像装置卡合连接的多个凸起112。该凸起112可实现卡口11与摄像装置的限位连接。可以理解，当卡口11为不同类型的卡口的时候，凸起112也可以省略。卡口11还可以通过其他对应类型的结构形式与摄像装置限位连接。
请再次参阅图4，套管122的外侧设有第一旋转螺纹126。旋转螺纹方向为正向螺纹。具体地，第一旋转螺纹126的螺纹凹槽。并且，套管122设有第一旋转螺纹126的高度大于伞骨20从完全打开到完全收折，伞骨20的枢轴24沿轴槽124上下移动到距离。
请同时参阅图5及图6，旋转盘13可旋转套设于套管122上。旋转盘13沿套管122的周向旋转，旋转盘13沿套管122的轴向升降。旋转盘13的内侧设于与套管122的第一旋转螺纹126啮合的第二旋转螺纹131。并且，第二旋转螺纹131为螺纹凸起。螺纹凸起与螺纹凹槽实现旋转连接。可以理解，第一旋转螺纹126也可以为螺纹凸起，第二旋转螺纹131相应为螺纹凹槽。此处对第一旋转螺纹126及第二旋转螺纹131的具体形状并不做 限定，只要第一旋转螺纹126与第二旋转螺纹131能够啮合连接即可。
具体地，旋转盘13的内侧设有延伸部132，该延伸部132沿旋转盘13的轴向向上或向下延伸，该延伸部上开设有第二旋转螺纹131。延伸部132可以增大了旋转盘13与套管122之间的接触面积，方便旋转盘13的转动。并且，延伸部132可以压持于压持面23上。
当旋转盘13相对于套管122转动的时候，旋转盘13可以沿第一旋转螺纹126及第二旋转螺纹131的轨迹转动。当旋转盘13相对于套筒旋转转动的时候，由于旋转螺纹的导向作用，在沿套管122的轴向方向上，旋转盘13升降运动。旋转盘13的升降运动会压持伞骨20的铰接端21。
当旋转盘13朝向卡盘12靠近运动的时候，铰接端21受到向下的压力，枢轴24转动并沿轴槽124向下运动，则伞骨20的另一端张开，从而使柔光布撑开。当旋转盘13背向卡盘12远离运动的时候，铰接端21不再受到压力，则可以将伞骨20复位收折。
请再次参阅图3，本实施方式的柔光箱的卡盘组件10还包括固定压板14。固定压板14套设于承载环121与旋转盘13之间。固定压板14可转动设于旋转盘13上。旋转盘13压持固定压板14，带动固定压板14压持伞骨20的铰接端21。
旋转盘13在旋转转动过程中，由于旋转盘13相对于伞骨20转动，旋转盘13与伞骨20的铰接端21之间存在摩擦力。并且，旋转盘13需要较大的压力压持伞骨20，则旋转盘13与伞骨20之间的摩擦力也较大。该摩擦力对旋转盘13的转动起到较大的阻碍作用。并且，多个伞骨20之间间隔设置，旋转盘13的受力不均匀，不利于旋转盘13的顺畅转动。
旋转盘13与固定压板14可转动连接，固定压板14相对于伞骨20不发生转动。旋转盘13转动与固定压板14之间存在摩擦力。由于该固定压板14的表面平滑，旋转盘13与固定压板14之间的压力均匀分布，则旋转盘13与固定压板14之间的摩擦力较小。因此，固定压板14可以避免旋转盘13受到较大的摩擦阻力，旋转盘13可以顺畅转动。
旋转盘13与固定压板14之间还设有限位结构。限位结构固定设于固定压板14上。请同时参阅图7，旋转盘13朝向固定压板14的一侧开设有用于避让限位结构的避空槽133。旋转盘13转动，限位结构于避空槽133内滑动。当限位结构运动至避空槽133的一端的时候，限位结构与避空槽133的侧壁相抵持，以限位旋转盘13的转动。因此，限位结构可以避免旋转盘13旋转超出其预定行程，避免旋转盘13从套管122上脱落，或者过度挤压伞骨20的抵接端。
具体在本实施方式中，请同时参阅图3，限位结构可以为螺钉40。螺钉40穿过旋转盘13固定于固定压板14上。对应地，旋转盘13开设有过孔(图未标)。该过孔仅是用于通过螺钉40，方便螺钉40的安装。固定压板14上对应设有用于固定该螺钉40的螺孔141。该螺钉40固定于固定压板14上，凸出于固定压板14的表面。该螺钉40的螺帽可以伸入于避空槽133内。
其中，避空槽133为弧形，其弧度对应所述旋转盘13的转动行程。当螺钉的螺帽与避空槽133的内侧壁相接触，抵持限位的时候，则该旋转盘13不能继续转动，从而达到对旋转盘13限位的目的。
具体地，避空槽133的弧度为60度-120度。即，该旋转盘13的转动行程为转动60度-120度。在该旋转行程范围内，方便操作人员转动，避免转动行程过大，操作人员需要绕柔光箱转动，同时也可以避免转动行程过小，旋转盘13的旋转阻力过大，导致转动困难。
请参阅图5及图6，本实施方式的柔光箱的卡盘组件10还包括弹性件15。弹性件15抵持于固定压板14与所述卡盘12的承载环121之间。固定压板14下降压持弹性件15收缩。弹性件15恢复形变固定压板14复位。
当旋转盘13及固定压板14向下压伞骨20的铰接端21的时候，则弹性件15随固定压板14的向下移动被压紧收缩。由于弹性件15被压缩具有弹性势能，当旋转盘13反向转动，松开对伞骨20的压持作用的时候，则弹性件15会恢复弹性形变，弹性件15恢复伸长。则固定压板14会被弹性件15顶起，回复至初始位。上述卡盘组件10通过弹性件15，可以使固定压板14自动复位，避免固定压板14在旋转盘13及卡板的承载环121之间晃动，影响卡盘组件10的稳定性。
请参阅图4，具体在本实施方式中，承载环121上设有凸柱127。凸柱127开设有螺孔128。请参阅图8，固定压板14与凸柱127相对位置处朝向凸柱127凸伸设有沉槽142。沉槽142的底部开设有可供凸柱127穿过的过孔143。请参阅图5及图6，当固定压板14相对于承载环121升降运动的时候，凸柱127沿过孔143伸缩运动。凸柱127与沉槽142通过螺钉60螺连接。螺钉60的螺帽61限位于沉槽142内。即过孔143的孔径大小小于螺帽61的直径大小，但过孔143的孔径大小大于螺柱62的直径大小，以保证螺钉60的螺柱62能够穿过过孔143，并且，螺帽61限位于沉槽142内。
当固定压板14远离承载环121的时候，螺钉60的螺帽61与过孔143底部的侧壁相抵持，避免螺帽61从沉槽142内脱离出来，导致固定压板14与承载环121相互脱离。
弹性件15套设于凸柱127及沉槽142的外侧。凸柱127及沉槽142可以对弹性件15的伸缩起到导向及限位的作用，避免弹性件15在伸缩过程中发生移位。弹性件15可以弹簧。
请参阅图9，卡盘12及旋转盘13的外侧面分别开设有辅助孔位129、139。辅助孔位129、139可以插入辅助转动销50，该辅助转动销50可以方便操作人员手持。并且，卡盘12及旋转盘13分别设有辅助孔位129、139，该两个辅助孔位129、139内分别设有辅助转动销50。操作人员的两手分别把持一个辅助转动销50，同时用力，增大转动力的力矩，可以方便将旋转盘13与卡盘12发生相对转动。
并且，辅助孔位129、139可以分别为多个。操作人员可以根据使用方便进行选择，选取其中两个，操作距离比较方便的辅助孔位129、139进行操作。因此，辅助孔位129、 139增强操作的便利性，更为人性化。
当转动完成之后，该辅助转动销50可以从该辅助孔位129、139上拆下，不影响该卡盘组件10的体积大小及正常使用。
上述柔光箱的卡盘组件10，可以避免操作人员使用较大力气支撑起各个伞骨20，通过转动旋转盘13即可将伞骨20撑开。并且，在收折伞骨20的时候，将旋转盘13反向转动，即可解除对伞骨20的压持限位，将伞骨20收折起来。因此，上述柔光箱的卡盘组件10可以避免操作人员费力操作，操作方便，提高柔光箱使用的便利性。
在其他实施方式中，弹性件15还可以省略。柔光箱的卡盘组件的结构还可以为如图10及图11所示。卡口31及旋转盘33均设置于卡盘32上。卡口31用于连接摄像装置或光源。旋转盘33相对于卡盘32转动，驱动伞骨20打开和收折。
请同时参阅图12，固定压板34上设有导向板342。导向板342朝向承载环321弯折凸起。并且，导向板342所在的平面与固定压板34所在的平面相互垂直。具体地，导向板342为多个，均匀分布于固定压板34朝向承载环321的侧面上。导向板342可以通过冲压、压制弯折形成。导向板342与固定压板34为一体结构，因此，其结构简单，制作方便。
请同时参阅图11，相应地，承载环321上开设有导向槽327。导向板342对应收容于导向槽327内。并且，导向板342的一侧面与导向槽327的内侧壁相抵持。并且，导向板342的形状与导向槽327的形状相适配。当导向槽327可以为弧形槽的时候，则导向板342的横截面也对应为弧形板。
并且，导向板342沿导向槽327滑动。导向板342的边缘进行圆角化，以便于导向板342沿导向槽327滑动。请参阅图13及图14，当固定压板14相对于承载环121升降运动的时候，导向板342沿导向槽327滑动。则导向板342与导向槽327的配合，可以对固定压板与承载环之间的相对运动起到导向作用。并且，固定压板34与承载环321的结构简单，便于实现。
并且，请参阅图15及图16，在其他实施方式中，卡盘32的套管322上还可以设置多周、连续环绕的第一旋转螺纹326。则旋转盘33的内侧也可以设置多周、连续环绕的第二旋转螺纹321。则多周第一旋转螺纹326与多周第二旋转螺纹321相互啮合旋转，使旋转盘13能够稳定地沿套管122的周向旋转。
虽然已参照几个典型实施方式描述了本发明，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本发明能够以多种形式具体实施而不脱离发明的精神或实质，所以应当理解，上述实施方式不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
