请参阅图1，本发明实施方式的固定结构10用于将负载连接在云台上。固定结构10包括热靴板11、热靴杆组件12、锁紧组件13和固定组件15。热靴板11包括相背的第一端11a和第二端11b。第一端11a设置有连接部111，第二端11b设置有滑动部112。热靴杆组件12包括能够拆卸地安装在连接部111上的固定杆122。热靴杆组件12通过连接部111的可拆卸连接从而使热靴板11能够固定在热靴杆组件12上的不同位置处。固定杆122包括相背的顶部1221与底部1222，底部1222用于连接云台。锁紧组件13用于将热靴杆组件12固定在热靴板11上。固定组件15与滑动部112配合并能将负载连接在滑动部112的任意位置。
具体地，负载可以为相机、手机、平板或传感器等获取外界信息及资讯的设备。云台可以为三轴云台、两轴云台或者单轴云台等。当负载连接在云台上时，云台能够稳定负载并能够改变负载的朝向、角度等。本发明实施方式以负载为相机(包括单反相机、摄像机、卡片相机、监控摄像头或者其他具有拍摄功能的电子装置)、云台为 三轴云台为例进行说明。
在将固定杆122安装在连接部111的过程中，固定杆122能够沿着垂直于第一端11a与第二端11b之间的方向移动，即沿着第一方向移动，直至固定杆122相对于连接部111具有合适的位置，例如，连接部111位于固定杆122长度的二分之一位置处、三分之一位置处或四分之一位置处，然后通过锁紧组件13将热靴杆组件12固定在热靴板11上。
在将负载连接在滑动部112的过程中，固定组件15能够和负载一起沿着第一端11a与第二端11b之间的方向滑动，即沿着第二方向滑动，直至固件组件和负载相对于滑动部112具有合适的位置后，例如，固定组件15和负载处于滑动部112的延伸方向的长度的二分之一位置处、三分之一位置处或四分之一位置处，然后通过固定组件15将负载固定在滑动部112。其中，第一方向与第二方向垂直。
本发明实施方式的固定结构10通过热靴杆组件12连接云台，通过固定组件15与滑动部112配合以连接负载，使得负载能够稳固的搭载于云台上，特别是当负载不能牢固的搭载在云台上时，可以实现负载的辅助固定。另外，由于固定杆122能够相对于热靴板11沿第一方向运动，负载能够相对于热靴板11沿第二方向运动，而云台是连接在固定杆122的底部1222的，因此可以实现负载相对于云台沿第一方向运动，或沿第二方向运动，或沿第一方向和第二方向运动，从而将负载移动至重心合适的位置，实现稳固搭载。
请一并参阅图1和图2，本发明实施方式的固定结构10包括热靴板11、热靴杆组件12、锁紧组件13、连接组件14和固定组件15。
热靴板11大致为矩形的长条状。热靴板11包括相背的第一端11a和第二端11b，也即是说，长条状的两端分别为第一端11a和第二端11b。第一端11a设置有连接部111，第二端11b设置有滑动部112。连接部111可包括通孔1111或盲孔，滑动部112可包括滑槽1121。
热靴板11包括上表面113、下表面114及侧面115。上表面113与下表面114位于热靴板11的相背两侧。当连接部111包括通孔1111时，通孔1111贯穿上表面113及下表面114；当连接部111包括盲孔时，盲孔为仅穿过上表面113的盲孔，或者为仅穿过下表面114的盲孔。通孔1111或盲孔的中心轴线方向为第一方向并垂直于上表面113和下表面114。滑槽1121贯穿上表面113及下表面114。滑槽1121的延伸方向为第一端11a与第二端11b之间的方向，即滑槽1121的延伸方向为第二方向。当负载为相机时，滑槽1121的延伸方向与相机的光轴垂直。
上表面113形成有冷靴槽116。冷靴槽116用于连接其他设备，例如麦克风、补 光灯等带有冷靴公头的设备。冷靴槽116位于第一端11a与第二端11b之间。冷靴槽116的数量可以为一个或多个。当冷靴槽116的数量为一个时，一个冷靴槽116位于第一端11a与第二端11b之间的中心区域；当冷靴槽116的数量为多个(例如两个、三个或四个)时，多个冷靴槽116等间距地分布在第一端11a与第二端11b之间。由于一个冷靴槽116位于第一端11a与第二端11b之间的中心区域，或者多个冷靴槽116等间距地分布在第一端11a与第二端11b之间，当其他设备连接在冷靴槽116时，有利于保证热靴板11均匀受力。冷靴槽116包括连通的上部1161及下部1162，上部1161的开口小于下部1162的开口。冷靴槽116可以为上表面113向下表面114的方向凹陷形成的阶梯形凹槽。在其他实施方式中，冷靴槽116也可以为上表面113朝远离下表面114的方向凸起1542形成的阶梯形凹槽。
上表面113设置有至少一个连接口117，例如，上表面113设置有一个、两个、三个或四个连接口117。上表面113的连接口117位于连接部111与冷靴槽116之间，和/或位于冷靴槽116与滑动部112之间。冷靴槽116的底壁15311也可设置有至少一个连接口1163，例如，冷靴槽116的底壁15311设置有一个、两个、三个或四个连接口1163。上表面113的连接口117和冷靴槽116的底壁15311的连接口1163均用于机械连接其他设备。由于上表面113设置有冷靴槽116、连接口117、冷靴槽116的底壁15311设置有连接口1163，固定结构10能够提供丰富的扩展接口以连接负载工作过程中所需要的其他设备，并减小负载本身接口的负荷，且外观结构简洁。热靴板11还可包括至少一个限位件118，例如限位螺丝。限位件118通过螺纹固定在上表面113，并在需要时为其他设备提供限位作用。
侧面115连接上表面113与下表面114。侧面115上设置有锁紧孔1151。
热靴杆组件12包括旋钮盖121和固定杆122。
旋钮盖121包括盖体1211和自盖体1211延伸的结合杆1212。结合杆1212上设置有外螺纹。固定杆122能够拆卸地安装在连接部111上。固定杆122包括相对的顶部1221与底部1222，底部1222用于连接云台。固定杆122为底部1222封闭、顶部1221设有开口12211的中空结构，以使得热靴杆组件12的质量较轻。
在一个实施方式中，旋钮盖121连接在顶部1221并遮挡住开口12211。顶部1221设置有内螺纹。结合杆1212伸入固定杆122内，结合杆1212上的外螺纹与顶部1221的内螺纹配合，以使得旋钮盖121与固定杆122连接。其中，结合杆1212上的外螺纹和顶部1221的内螺纹均不外露。盖体1211遮挡开口12211，以防止灰尘、水分或其他物质由开口12211进入固定杆122内。
在另一个实施方式中，热靴杆组件12还包括延长杆123。延长杆123用于在固定 杆122长度无法满足需求时，起到延长的作用。延长杆123包括相对的连接端1231与开口端1232，连接端1231连接在顶部1221并遮挡开口12211。旋钮盖121连接在开口端1232并遮挡住开口端1232。顶部1221设置有内螺纹，连接端1231设置有外螺纹。连接端1231的外螺纹与顶部1221的内螺纹配合，以使得延长杆123与固定杆122连接，其中，连接端1231的外螺纹和顶部1221的内螺纹均不外露。开口端1232设置有内螺纹，结合杆1212伸入固定杆122内，结合杆1212上的外螺纹与开口端1232的内螺纹配合，以使得旋钮盖121与延长杆123连接，其中，结合杆1212上的外螺纹与开口端1232的内螺纹均不外露。盖体1211遮挡开口端1232，以防止灰尘、水分或其他物质由开口端1232进入延长杆123内。
固定杆122和延长杆123可均采用铝合金材料制成。铝合金材料密度较小且强度较高，有利于保证负载与云台的连接强度和安全性，也不会过多增加质量。
当热靴杆组件12包括旋钮盖121和固定杆122时，或者包括旋钮盖121、固定杆122和延长杆123时，固定杆122的底部1222开设有连接孔12221以连接云台的轴臂。当负载为相机时，连接孔12221的中心轴线与相机的光轴垂直。
在其他实施方式中，固定杆122和延长杆123在沿第一方向上的相对位置关系可以互换，或者热靴杆组件12可以包括一个固定杆122和多个延长杆123；或者包括多个固定杆122和一个延长杆123；或者包括多个固定杆122和多个延长杆123等。

调节螺杆152与调节旋钮151固定连接。调节螺杆152穿过滑槽1121，调节螺杆152包括杆体1521及阻挡部1522，阻挡部1522位于杆体1521的远离调节旋钮151一端，杆体1521的远离阻挡部1522的一端收容在凹槽内。紧固件156穿设在侧孔1514内并与杆体1521固定连接。具体地，紧固件156可以直接与杆体1521伸入凹槽的杆体1521部分抵触以使得调节螺杆152与调节旋钮151固定连接；或者，伸入凹槽的杆体1521部分上设置有内螺纹，紧固件156上设置有外螺纹，紧固件156上的外螺纹与杆体1521上的内螺纹螺合，以使得调节螺杆152与调节旋钮151固定连接。
上固定块153设置下表面114所在的一侧，调节螺杆152穿过上固定块153。上固定块153开设有上凹陷1531。上固定块153的侧壁1532设置有至少一个连接口15321。例如，上固定块153的侧壁1532设置有一个、两个、三个或四个连接口15321。连接口15321用于机械连接其他设备，例如跟焦马达固定杆等。由于上固定块153的侧壁1532设置有至少一个连接口15321，固定结构10能够提供丰富的扩展接口以连 接负载工作过程中所需要的其他设备，并减小负载本身接口的负荷。
下固定块154设置下表面114所在的一侧，下固定块154穿设在上固定块153内，调节螺杆152穿过上固定块153后与下固定块154螺接，阻挡部1522阻挡住下固定块154。。具体地，下固定块154包括本体1541和自本体1541两侧分别延伸的凸起1542，凸起1542与负载的热靴槽配合以固定负载。本体1541收容在上凹陷1531内，本体1541包括相背的第一面15411与第二面15412。第一面15411位于上凹陷1531内，第一面15411朝第二面15412凹陷形成收容槽15413，第二面15412朝第一面15411凹陷形成下凹陷1543，阻挡部1522与下凹陷1543的底壁15311抵触。
固定垫片155套设在调节螺杆152上并夹设在调节旋钮151与上表面113之间。固定垫片155可以为环形的垫片。固定垫片155采用耐磨材料，例如聚甲醛树脂(polyoxymethylene，POM)、高碳钢、铸铁、金刚石等等。
固定弹性件157的一端与上固定块153结合，另一端与下固定块154结合。具体地，固定弹性件157收容在收容槽15413内。固定弹性件157的一端与上凹陷1531的底壁15311结合，另一端与收容槽15413的底壁15311结合。固定弹性件157可以为弹簧，以为下固定块154与上固定块153之间提供预张力。固定弹性件157的数量为多个，多个固定弹性件157围绕调节螺杆152均匀分布。例如，固定弹性件157的数量为两个，此时，收容槽15413的数量也为两个，两个固定弹性件157为下固定块154与上固定块153之间提供均匀的预张力。
安装时，调节螺杆152与调节旋钮151通过紧固件156固定连接，调节旋钮151转动带动调节螺杆152转动，调节螺杆152转动使得下固定块154在上固定块153的限制下沿着杆体1521移动，例如：顺时针转动调节螺杆152，则下固定块154沿着杆体1521向下移动；逆时针转动调节螺杆152，则下固定块154沿着杆体1521向上移动，如此，能够通过调节下固定块154在杆体1521上的位置来方便与不同负载的热靴槽结合。
在其他实施方式中，调节螺杆152也可以不形成阻挡部1522，调节旋钮151与调节螺杆152为一体的结构。此时，可以先将下固定块154与负载的热靴槽结合，再将转动调节旋钮151，以将调节螺杆152与下固定块154旋紧。
本发明实施方式还提供一种云台系统。云台系统包括云台、负载和上述任一实施方式的固定结构10。固定结构10用于将负载连接在云台上。
本发明实施方式的云台系统通过热靴杆组件12连接云台，通过固定组件15与滑动部112配合以连接负载，使得负载能够稳固的搭载于云台上。
