随着电机技术的发展，电机已经广泛的应用在了我们的生活中。比如由电机带动窗帘运动，就成为了可由电机控制的电动窗帘，方便了人们的生活。
电动窗帘主要靠被驱动装置带动的皮带移动实现窗帘的打开或关闭，通常电动窗帘驱动装置主要设有驱动电机，驱动电机通过变速箱带动传动皮带移动，驱动平开或卷帘式窗帘的开闭，这类电动窗帘在安装、调试或维修时，如果皮带轮与变速箱保持传动连接状态，操作会很不方便，将皮带轮与变速箱脱离开，才能便于安装或调试，而且由于电动窗帘驱动器通常要安装在隐蔽处，根据设计要求，占用的空间受到很大限制，所以其体积要求尽可能小。

具体的，当所述主轨道231滑动时，带动所述传动机构400滑动，以使所述皮带遮挡件500随着所述传动机构400滑动而滑动，使所述皮带遮挡件500可随着所述主轨道231的位置变化而调整位置，实现实时遮挡第二皮带253，避免所述第二皮带253脱离所述第二皮带253区121。
进一步的，所述固定部410为波浪形槽，所述皮带遮挡件500与固定部410固定连接的一端弯折成与波浪形槽相匹配的形状，使所述皮带遮挡件500可以固定在传动机构400上与其一起固定，其中，所述固定部410也可以是使用螺钉固定或固定销固定，实现皮带遮挡件500与所述传动机构400固定的作用即可，可根据实际情况选择；具体的，所述第一导向轮设置在内传动箱体远离所述主轨道231的一端上，所述第一导向轮与内传动箱体远离主轨道231的一端之间设有通孔，所述通孔接通外界和内传动箱体内部，所述皮带遮挡件500一端通过通孔伸入内传动箱体内部，然后与波浪形槽相匹配，实现固定的作用。
其中，在本实施例中，所述皮带遮挡件500为钢带，皮带遮挡件500为金属制成，以使所述皮带遮挡件500在滑动过程中因摩擦产生的热量能快速散发，散热效果好，且相比起使用塑料制成的皮带遮挡件500而言，不容易变形；当然，所述皮带遮挡件500还可为其它材质制成，具体的本处不做赘述，根据实际情况选择即可，所述钢带的厚度为0.1mm，也可为0.2mm，厚度做薄，减少所述钢带的重量，以使所述电动窗帘增加皮带遮挡件500后的整体重量基本不变。
进一步的，所述钢带的长度大于等于所述副轨道232的长度，以使所述钢带可完全遮挡住所述开口处的第二皮带253，避免所述第二皮带253与所述第二皮带253区121脱离。

如图3所示，作为本申请的第二实施例的一种改进，所述主轨道231靠近所述第二皮带区250的一侧上设有阻隔板300，所述阻隔板300与分隔板结合使用，以使当所述皮带遮挡件500上未遮挡第二皮带253的部分收纳在所述副轨道232内时，所述皮带遮挡件500受到震动或重力的影响，脱离所述主轨道231区而进入副轨道232区，对第二皮带253造成影响。

所述伸缩轨道还包括外轨道，所述外轨道与所述副轨道相互滑动设置，所述副轨道可滑动收纳至所述外轨道内，在本实施例中，所述副轨道的长度小于等于所述外轨道的长度，以使当所述副轨道滑动收纳至所述外轨道内时，所述副轨道被隐藏在所述外轨道内，在使用过程中，所述副轨道与所述主轨道滑动伸缩时，所述副轨道从所述外轨道的一端处伸出所述外 轨道内部，在外界看来是所述外轨道与所述副轨道之间伸缩设置，其中，当所述副轨道可滑动收纳至所述外轨道内时，所述外轨道对所述副轨道起到一个保护的作用，避免所述副轨道受到外力冲击而导致变形，从而影响所述副轨道与所述主轨道之间的滑动，造成伸缩轨道无法使用，可选的，所述主轨道、副轨道和外轨道三者之间的重合长度大于等于两米，以便于适配不同长度的窗台。
在所述电动窗帘还设有离合器，所述第一皮带和第二皮带均设有一同步带轮，两个所述同步带轮分别与所述离合器的两端连接，实现离合，对于离合器的具体设计，参照如下实施例。
如图10和图11所示，作为本申请的一实施例，公开了一种离合器结构100,所述离合器结构100包括第一传动端110、第二传动端120和离合轴芯130，所述第一传动端110内部中空设置，形成第一通孔111；所述第二传动端120内部中空设置，形成第二通孔121，与所述第一传动端110同心设置；第一传动端110和第二传动端120形状结构相同，可以使用相同模具制作，第一传动端110和第二传动端120之间设有间隔，所述离合轴芯130穿过所述第二传动端120，伸入到所述第一传动端110的中部；第一通孔111和第二通孔121的孔壁与所述离合轴芯130的外壁相啮合，离合轴芯130转动的时候可以使得第一传动端110和第二传动端120进行转动。而且，所述第一传动端110和第二传动端120分别与第一皮带241和第二皮带253的同步带轮220固定连接。

作为本申请的第二实施例，如图13和图14所示，所述控制部133包括按键帽134和弹性件135，所述弹性件135包括但不限于弹簧136，其他弹性件135也是可以的，所述弹簧136套设在所述第二结构部132的外围，所述弹簧136的两端分别抵接所述按键帽134和所述第二传动端120远离所述第一传动端110的一端；所述离合器结构100包括固定外壳140，所述外壳的内壁上设置有滑槽234，所述按键帽134上设置有限位结构137，所述按键帽134可沿所述外壳设计的槽位滑动；所述第二结构部132与所述按键帽134之间设置有第二圆柱体150，所述第二圆柱体150的外径大于所述六菱柱体1311的外径，所述第二圆柱体150与所述第一圆柱体1321一体成型。

如图15和图16所示，作为本申请的另一实施例，公开了一种电动窗帘200，所述电动窗帘200包括如上任一所述的离合器结构100以及两组同步带210，所述两组同步带210均设有一同步带轮220，沿离合轴芯130的移动方向，所述两组同步带210呈上下排列，两个所述同步带轮220分别与所述第一传动端110和第二传动端120固定连接；所述第一传动端110的外径等于所述同步带轮220的内径，所述第一传动端110的底部与所述第二传动端120对应的同步带轮220的顶部抵接。
上下并列两组同步带210，均设有一同步带轮220，且同步带轮220为同心设计，中心设有一可上下移动的离合轴芯130，离合轴芯130上部分为六角设计，与同步带轮220配合可实现联动，下半部分为圆柱设计，与同步带轮220为相对打滑运动。
参考图10和图16为正常使用状态，离合轴芯130为行程下止点，六角部分同时连接了主动和从动同步带轮220，可将主动同步带轮220的旋转动力传递到从动同步带轮220实现两组同步带210同时运转。参考图11，当按下并旋转按键帽134至45度时，按键帽134锁定为动力脱开状态，离合轴芯130处于行程上止点，主动同步带轮220与离合轴芯130处于 打滑状态，主动同带轮与离合轴芯130相互都不能带动运转，从来实现动力的脱开；反转按键帽134至45度，可使离合轴芯130在弹簧136的作用下，回到行程下止点状态，实现联动运转。
当然，本申请中的离合器结构100还可以用于其它款式的窗帘中，并不局限于上述实施例中的电动窗帘200。
以上内容是结合具体的可选的实施方式对本申请所作的详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
