发明实施例
本发明的实施方式
为了使本领域技术人员能够更加清楚地理解本发明，下面将结合附图及具体实施例对本发明做进一步详细的描述。
图1和图2分别为本发明第一实施例示出的电动摄影杆的结构示意图和模块示意图，结合图1和图2所示，该电动摄影杆包括驱动组件、控制模块10和多节相互套接的套管20，所述驱动组件设置在多节套管20内，用于驱动多节套管20进行伸缩运动；控制模块10包括设置在多节套管20上的控制壳体11，设置在控制壳体11内的主控制器12和主电池13，以及设置在控制壳体11外壁上的可视屏幕40、可转动的手轮50和按键组件60，主控制器12分别电连接所述驱动组件、可视屏幕40、手轮50、按键组件60和主电池13，主电池13用于为控制模块10和驱动组件进行供电，主控制器12用于接收手轮50和按键组件60产生的控制指令，并依据所述控制指令控制多节套管20的伸缩运动。上述控制模块10可通过按键组件60和手轮50的双重操作方式实现对摄影杆的运动控制和参数调节，操作非常方便；另外，可视屏幕40可用于显示摄影杆的功能参数，方便用户直观的观察摄影杆当前的状态参数，以便于摄影杆实现更多的功能。
进一步地，多节套管20至少包括第一管21、可伸缩地安装于第一管21内的第二管22和可伸缩地安装于第二管22内的第三管23；所述驱动组件包括驱动装置30和传动组件，驱动装置30固定设置在第一管21内远离第二管22伸缩端的一端，所述传动组件一端连接驱动装置30的动力输出端，所述传动组件的另一端分别连接第二管22和第三管23，用于驱动第二管22和第三管23同步进行伸缩运动。
其中，第一管21、第二管22和第三管23均为轻质高强度管，例如纤维材质制成的纤维管，第二管22的外径略小于第一管21，第三管23的外径略小于第二管22，第二管22可整体或部分收缩到第一管21内，第三管23可整体或部分收缩到第二管22内。上述第二管22和第三管23在驱动装置30的带动下能够同步进行伸缩运动，使得本发明提供的电动摄影杆的伸缩速度可以达到常规两节摄影杆的两倍，从而能够更加快速精准地将摄影杆的长度调节到位。当然，在其他一些实施例中，可以根据需要按照上述方案复制拓展，如在第三管23内安装可伸缩的第四管，第四管同样连接该传动组件，用于驱动第四管相对第三管进行伸缩，以至于在第四管内也可安装可伸缩的第五管，可以此类推连接需要的套管数量，以满足使用的需求。
本发明第一实施例中，控制壳体11固定设置在第一管21远离第二管22伸缩端的端部上，与多节套管20形成一体结构；驱动装置30包括驱动控制器31以及连接驱动控制器31的电机32，驱动控制器31连接主控制器12，用于接收主控制器12发送的控制指令；电机32安装在第一管21内远离第二管22伸缩端的一端，电机32的动力输出端连接所述传动组件，用于依据所述控制指令控制传动组件进行运动。上述电机32采用伺服旋转电机，通过电机的正转和反转可带动多节套管20进行伸长和缩短，从而实现升降杆20的升降功能；同时，由于伺服电机对升降杆控制几乎没有惯性产生，可以实现高精度的定位控制。
进一步地，该电动摄影杆还包括拓展座24，拓展座24安装在第一管21朝向第二管22伸缩端的外壁上，拓展座24上设有用于与外部设备连接的拓展部，该拓展部包括沿拓展座24径向设置的安装孔和卡口。上述拓展部能够配合脚架等外部设备做横向使用，克服了现有单节或多节延长杆只能在两端与其他设备拓展连接的局限性。
控制壳体11背离多节套管20的端部上还安装有防脱脚垫15和设置在防脱脚垫15中间的第一拓展端子16，第一拓展端子16用于与外部设备连接，实现摄影杆端部的拓展连接，防脱脚垫15为具有一定弹性摩擦力的硅胶垫，可有效防止外部设备的脱落。
第三管23的伸出端上安装有第二拓展端子25，第二拓展端子25背向第三管23的端部上设置有用于与外部设备连接的安装孔，从而实现摄影杆的端部拓展连接；另外，第二拓展端子25背离第三管23的一侧沿径向凸起设置有一法兰盘，法兰盘朝向第三管23的一侧安装有缓冲圈，该法兰盘的外径大于第一管21的外径，当第三管23和第二管22整体缩回第一管21的内部后，第二拓展端子25的法兰盘隔挡在第一管21的端部，起到限位封堵的作用。
第一管21远离第二管22伸缩端的一端上还套设有手持护套26，手持护套26为弹性橡胶材料制成，能够起到缓冲作用，从而有效的避免了第二管22和第三管23整体缩回第一管21的内部后，第二拓展端子25与拓展座24和第一管21的碰撞。
图3是本发明第二实施例示出的电动摄影杆的部分结构示意图，如图3所示，第一管21远离第二管22伸缩端的端部上固定设置有安装部27，安装部27上开设有容置槽271，控制壳体11可拆卸安装在容置槽271内，使得控制模块10可从多节套管20上拆卸下来，形成独立的可远程操控的控制模块。
具体的，控制壳体11的两相对端面上分别开设有一连接卡槽17，容置槽271内的两相对端面上分别设置有一连接卡扣272，连接卡扣272通过弹簧与安装部27弹性连接；安装部27上还开设有连通容置槽271的导向槽273，导向槽273与手轮50和控制壳体11之间的连接柱的外形轮廓一致。当安装控制模块10时，将该连接柱沿导向槽273滑入，连接卡扣272按照行程进入连接卡槽17内并与其卡合连接，即可完成控制模块10的安装；连接卡槽17和连接卡扣272上设置有导向斜面，当向外拔出控制壳体11时，连接卡扣272可沿着导向斜面脱离连接卡槽17，即可完成控制模块10的拆卸，实现了本发明第二实施例提供的控制模块10的快速安装与拆卸，方便使用。
进一步地，按键组件60包括分别连接主控制器12的第一按键61、第二按键62和第三按键63；第一按键61设置在手轮50上，用于开启或关闭电源；第二按键62 和第三按键63与可视屏幕40设置在控制壳体11的同一侧面上，第二按键62用于控制摄影设备，包括但不限于单击控制摄影设备开设录制，双击控制摄影设备进行拍照；第三按键63用于调节设备参数，包括但不限于菜单翻页和伸缩速度调节等，使得该电动摄影杆的操作更加方便快捷。
本发明第一实施例中，第三按键63采用具有上下左右四个触点的多方向按键(详见图1)，第二按键62设置在该多方向按键中间，可通过多方向按键的上下左右四个触点控制杆体的伸缩速度和可视屏幕40的菜单翻页和参数调节；本发明第二实施例中，第三按键63的数量为四个，四个第三按键63围合形成环状结构，第二按键62设置在四个第三按键63中间，同样的，可通过上下左右四个第三按键63分别控制杆体的伸缩速度和可视屏幕40的菜单翻页和参数调节，操作非常方便。
需要说明的是，在本发明第二实施例中，由于控制壳体11安装在安装部27内，因此，防脱脚垫15和第一拓展端子16均设置有安装部27远离套管20的端面上，其作用与第一实施例中相同，在此不再赘述。
图4是本发明第二实施例示出的电动摄影杆的模块示意图，如图4所示，本发明第二实施例提供的控制模块10还包括设置在控制壳体11内的无线发射器14，无线发射器14连接主控制器12，用于与驱动装置30建立无线通讯连接，无线通讯连接方式包括但不限于蓝牙连接和3G/4G/5G等通信协议连接；驱动装置30除了包括驱动控制器31和连接驱动控制器31的电机32外，还包括分别连接驱动控制器31的驱动电池33和无线接收器34，无线接收器34与无线发射器14无线通讯连接，电机32和驱动电池33安装在第一管21内远离第二管22伸缩端的一端，电机32的动力输出端连接传动组件；驱动电池33为可充电电池，可在第一管21的外侧设置充电接口为驱动电池33充电，驱动电池33也可通过拆卸的方式进行充电。
本发明第二实施例中，驱动电池33用于为驱动装置30供电，主电池13用于为控制模块10供电，无线发射器14和无线接收器34能够建立控制模块10和驱动装置30的远程通讯连接，从而可将控制模块10单独拆卸下来使用，便于远程操控，减少用户不必要的走动，提高拍摄效率。
图5是本发明实施例示出的手轮爆炸图，如图5所示，手轮50包括可转动地安装 在控制壳体11侧壁上的手轮壳体和安装在所述手轮壳体内的手轮连接轴58，手轮连接轴58一端固定连接控制模块10，手轮连接轴58的另一端可拆卸安装有手轮控制板54，手轮连接轴58外套设有至少一个的轴承581，所述手轮壳体的内壁连接轴承581；
所述手轮壳体的内壁上还安装有朝向手轮控制板54设置的磁环56，磁环56与手轮连接轴58同轴设置，所述手轮壳体用于带动磁环56进行同步转动；手轮控制板54电连接主控制器12，用于检测磁环56的旋转位置生成所述控制指令并发送到主控制器12。上述手轮控制板54上集成有霍尔传感器芯片，用于检测磁环56的旋转位置产生不同的控制指令，能够实现了套管伸缩运动的无极调速，调节精度高，也能够根据磁环56的旋转方向方便地控制套管的伸缩方向，操作便利，且磁环56和手轮控制板54没有直接接触，能够避免长期使用造成的磨损失效，提高手轮的使用寿命。
本实施例中，手轮连接轴58的一端固定连接控制模块10，可以是控制壳体11，也可以是控制模块10内的其他固定连接件；手轮连接轴58远离控制模块10的一端设置有电路板安装座582，手轮控制板54可拆卸安装在电路板安装座582上，电路板安装座582能够增大手轮控制板54和手轮连接轴58的接触面积，从而能够将手轮控制板54更加稳固地安装在所述手轮壳体内；手轮连接轴58呈中空设置，可用于穿设手轮控制板54和主控制器12的连接线；
轴承581的数量为两个，两个轴承581沿手轮连接轴58的轴向间隔设置。上述轴承581实现了手轮壳体和控制壳体11的转动配合，受力点主要在轴承位置，由于轴承的承载能力较强，因此能够提高手轮结构的使用寿命，且轴承能够保证手轮旋转平滑，使用过程中无钝挫感，从而为用户提供良好的使用体验。
具体的，所述手轮壳体包括手轮外壳51、导光柱52、手轮盖板53和连接轴固定套59，连接轴固定套59套设安装在轴承581外，手轮外壳51可拆卸安装在连接轴固定套59上，手轮外壳51远离控制壳体11的一端设置有开口，导光柱52可拆卸安装在所述开口上，磁环56安装在导光柱52朝向控制壳体11的一侧，手轮盖板53相对磁环56安装在导光柱52的另一侧；
