附图说明
图1是本发明一个实施例的电动绞盘的结构简图；
图2是本发明一个实施例的电动绞盘的剖面结构示意图；以及
图3是本发明另一个实施例的电动绞盘的剖面结构示意图。
具体实施方式
为了更好的说明本发明，下面结合附图及具体实施例对本发明做进一步说明。可以理解的是，这些具体实施例均为示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
如图1、图2、图3所示，本发明提供一种电动绞盘，其包括绞盘主体100；用于向绞盘主体100提供驱动力的驱动电机200；用于向驱动电机200提供动力的锂电池300；和电连接在锂电池300与驱动电机200之间的、用于以控制驱动电机200的电机控制器400。该驱动电机采用无刷电机，无刷电机没有电刷，因而也没有相关接口，因此本发明提供的电动绞盘的结构更简单，噪声更小，使用寿命更长。
如图2、图3所述，本发明提供的电动绞盘的绞盘主体100包括：绞盘支架102， 减速箱104，以及绞索鼓轮106。驱动电机200固定安装在绞盘支架102上，减速箱104与驱动电机200相连接，进而减速箱104可以接收驱动电机200传递过来的驱动力，绞索鼓轮106与减速箱104相连接，并且，绞索鼓轮106可以被减速箱104带动而进行转动。
本发明提供的电动绞盘的工作过程可以简述如下：电机控制器400控制驱动电机200开始工作后，驱动电机200开始旋转，此时减速箱104在驱动电机200的驱动下进行转动，将扭矩进行放大后，进而带动绞索鼓轮106进行转动，实现绞索(如钢索、绕绳等)的收放。
通常而言，电动绞盘内的驱动电机200的功率一般较小，只有几马力，其不足以进行牵引、起重、拖拉等工作，因此，在电动绞盘进行作业时需要通过减速箱104将扭矩进行放大。可以理解的是，本发明对减速箱104的具体结构没有特殊的限制，其可以为本领域各种常用的减速结构。例如，在一些实施例中，本发明提供的减速箱104为行星齿轮减速机构，行星齿轮减速机构的体积小，进而能进一步减少电动绞盘的体积，而且，行星齿轮减速机构产生的减速比相对较大，使用寿命较长。
如图2、图3所示，在本发明的一些实施例中，电机控制器400具有电机控制器壳体401，驱动电机200具有电机壳体201，电机控制器壳体401与电机壳体201连通。可以理解的是，此处的“连通”是指电机控制器壳体401的内部腔体与电机壳体201的内部腔体相通，即冷却介质(如空气)可以在电机控制器壳体401与电机壳体201中互相流动。继而，通过相互连通的电机控制器壳体401与电机壳体201，可以扩大驱动电机200和电机控制器400的散热空间，提高散热效果。
进一步的，在一些实施例中，如图2、图3所示，在电机壳体201上可以开设有排风口202，在电机控制器壳体401上可以设置有进风口402，在驱动电机200内设置有电机风叶204，电机风叶204可在驱动电机200工作时旋转。也就是说，当本实施例的电动绞盘在工作的时候，通过电机风叶204的旋转，可以将外界冷空气从进风口402处吸入电机控制器壳体401内，并经过电机壳体201内部后通过排风口202将热量排出去，对电机控制器400和驱动电机200进行散热，即电机风叶204的风道先通过电机控制器400，再通过驱动电机200，可以使得两个部件一起加快散热，整机的散热效果非常好。
如图2所示，在本发明的一些实施例中，驱动电机200固定安装在绞盘支架102的一端(如附图2中绞盘支架102的右侧)，减速箱104设置在绞盘支架102的另一端 (如附图2中绞盘支架102的左侧)；绞盘主体100上还设有传动轴108，驱动电机200与减速箱104之间通过该传动轴108进行连接。进而，驱动电机200在工作时，其驱动力通过该传动轴108传输至减速箱104。
为了进一步减少震动和噪音，在本发明的一个实施例中，在驱动电机200与传动轴108之间还设置有柔性连接器110，即，驱动电机200具有驱动轴206，该驱动轴206与传动轴108之间通过柔性连接器110进行连接。可以理解的是，本实用性对柔性连接器110没有特殊限制，其可以为本领域技术人员公知的各种柔性连接器，只要其可以适用于电动绞盘中即可。
如图2所示，在本发明的一个实施例中，绞索鼓轮106套设在传动轴108上，且绞索鼓轮106可绕传动轴108旋转。可以理解的是，绞索鼓轮106可以直接套设在传动轴108上，也可通过支撑结构套设在传动轴108上。由此，驱动电机200、减速箱104与绞索鼓轮106之间为直线横向排布，使得本发明的电动绞盘的整体结构更加紧凑，体积比常规的电动绞盘更小。同时，由于绞索鼓轮106是套设在传动轴108上的，即绞索鼓轮106设置在减速箱104和驱动电机200之间，进而可以进一步的减少电动绞盘的轴向尺寸，从而减少电动绞盘的体积。可以理解的是，在此实施例中，绞索鼓轮106的左侧与减速箱104连接，例如可以通过齿轮结构进行啮合；而绞索鼓轮106的右侧为自由端，绞索鼓轮106由减速箱104带动而旋转，实现绞索(如钢索、绕绳等)的收放。
如图2所示，在此实施例中，绞索鼓轮106是通过支撑结构套设在传动轴108上的，该支撑结构可绕传动轴108旋转。该支撑结构包括垂直于传动轴108的支撑板110和套设在传动轴108上的与支撑板110连接的支撑套筒112，该支持套筒112可绕传动轴108旋转。可以理解的是，支撑板110可以由均匀分布在支撑套筒112外周的多个支撑板筋构成，也可以为分布在支撑套筒112外周的环状的一整块支撑板。
在本发明的另一个实施例中，如图3所示，减速箱104的输入端(如图3中减速箱104的右侧)与驱动电机200连接，即驱动电机200的驱动轴206与减速箱104的输入端连接；而减速箱104的输出端(如图3中减速箱104的左侧)与绞索鼓轮106连接，且驱动电机200与绞索鼓轮106分别设置在减速箱104的两侧。由此，驱动电机200、减速箱104与绞索鼓轮106之间为直线横向排布，使得整体结构更加紧凑，体积比常规的电动绞盘更小。
如图3所示，绞索鼓轮106具有鼓轮轴107，鼓轮轴107穿过绞盘支架102与减速 箱104的输出端连接，为进一步减少绞索鼓轮106与绞盘支架102之间的震动及噪音，在鼓轮轴107与绞盘之家102之间还可以设置减震弹簧109，如图3所示，在此实施例中，减震弹簧109套设在鼓轮轴107上，其一端低靠或连接在绞索鼓轮106上，另一端低靠或连接在绞盘支架102上。
可以理解的是，对于电动绞盘的其他结构可以采用本领域技术人员所公知或常用的结构，本发明不再做详细赘述。同样的，本发明提供的电动绞盘还可以含有其他本领域常用的结构或部件，例如，电动绞盘还可以包括一个绞索引导器，该绞索引导器能将绞索(如钢索、绕绳等)直接引向或者以一定角度引向绞索鼓轮。
根据本发明提供的电动绞盘，其采用独立的锂电池作为驱动电源，通过电机控制器控制输出，进而驱动无刷电机带动绞盘鼓轮转动，采用锂电池加无刷电机技术具有体积小、寿命长、噪音小、便于携带等优势。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
