0的管体， 所述传动轴 54穿设于所述穿孔 5220。 本实施例通过贯穿设置传动轴 54 ， 可以简化第一卷轴 522与传动轴 54的连接结构， 方便组装及降低成本。
[0029] 在本发明又一个可选实施例中， 设置有多个平面渦卷弹簧机构 52, 所述传动轴 54穿设于各平面渦卷弹簧机构 52的第一卷轴 522的穿孔 5220。 本实施例通过设置 多个平面渦卷弹簧机构 52, 从而可以极大限度地减小所采用的电机组件的功率 ， 以降低能耗和运行噪音。
[0030] 在本发明一个可选实施例中， 所述传动轴 54与穿孔 5220的横截面相匹配且均为 非圆形横截面， 例如： 横截面可以为正方形、 矩形、 椭圆形、 三角形、 五边形 、 六边形等各种非圆形。 本实施例通过采用非圆形横截面的传动轴 54和相匹配 的穿孔 5220进行配合， 可以有效实现传动轴 54和第一卷轴 522之间的旋转动力传 递， 而且在进行组装时， 仍然可以很方便地将传动轴 54穿过第一卷轴 522上的穿 孔， 组装方便。
[0031] 在本发明又一个可选实施例中， 所述电机组件 50包括电机和连接于电机的输出 轴的减速箱， 减速箱的输出轴作为电机组件 50的输出轴与所述传动轴 54周向固 定连接。 通过采用电机和减速箱搭配使用， 使输出轴的转速较低， 输出扭矩大 ， 安全性更高， 而且也还可采用一些输出转速较高的电机， 降低对电机的要求 ， 有利于电机的选用。
[0032] 在具体实施时， 为保障窗体 2运动的平稳性， 收绳装置 4一般会设置两个或更多 ， 而驱动装置 5的电机组件 50和平面渦卷弹簧机构 52与收绳装置 4的相对位置关 系可以多变， 例如， 在如图 1至图 2所示的实施例一以及图 4所示的实施例二中， 电机组件 50和平面渦卷弹簧机构 52之间设置有一个收绳装置 4, 而在平面渦卷弹 簧机构 52的另一端再设置另一个收绳装置 4, 其中， 图 4所示实施例二和图 1至图 2所示实施例一的区别主要在于： 所述第一卷轴 522的两端分别设置有转接轴杆 5 21 , 分设于第一卷轴 522两端的所述转接轴杆 521—端与第一卷轴 522同步旋转连 接而另一端分别与一传动轴 54连接， 从而可以以一端的转接轴杆 521接受该端连 接的一传动轴 54传递过来的动力， 再通过第一卷轴 522、 另一端的转接轴杆 521 而将动力传递到该另一端所连接的另一传动轴 54上， 不仅实现驱动第一卷轴 522 旋转的功能， 还实现了动力的传递。 而在如图 5所示的实施例三中， 则是电机组
件 50直接与平面渦卷弹簧机构 52后再通过传动轴 54依次连接两个收绳装置 4。
[0033] 如图 8至图 9所示的本发明可选实施例中， 所述电机为在相反方向上分别设置有 输出轴的电机， 电机的每一输出轴均连接有减速箱， 且每一减速箱的输出轴分 别连接一根传动轴 54， 每一传动轴 54均连接有一收绳装置 4， 且至少一传动轴 54 上还连接有至少一平面渦卷弹簧机构 52。 通过采用双向设输出轴的电机， 可以 将电机组件 50设置于中间， 而将收绳装置 4分设置于电机组件 50的两端， 从而可 以方便根据产品空间特点以及设计需求进行合理布局。 具体实施时， 如图 8所示 的实施例五是在图 1所示实施例一的基础上， 将其中的电机组件 50替换为采用了 在相反方向上分别设置有输出轴的电机的电机组件 50， 并将电机组件 50和平面 渦卷弹簧机构 52相连后置于中间， 而两个收绳装置 4分别置于靠两端位置。 图 9 所示的实施例六则是在图 6所示实施例四基础上， 将其中的电机组件 50替换为采 用了在相反方向上分别设置有输出轴的电机的电机组件 50， 并将电机组件 50和 平面渦卷弹簧机构 52相连后置于中间， 而两个收绳装置 4分别置于靠两端位置。
[0034] 在本发明又一个可选实施例中， 如图 6及图 7所示， 所述传动轴 54由所述平面渦 卷弹簧机构 52分隔为相互独立的第一段和第二段且所述平面渦卷弹簧机构 52的 第一卷轴 522和第二卷轴 524均垂直于所述传动轴 54设置， 所述第一卷轴 522的一 端还分别设置有共轴的第一传动齿轮 530, 第二卷轴 524的一端还分别设置有共 轴的第二传动齿轮 531， 所述平面渦卷弹簧机构 52还包括分别设置于所述支架 52 0相对两端的输入端传动杆 532和输出端传动杆 533 , 所述输入端传动杆 532外端 与传动轴 54的第一段传动连接而内端设置有第一锥齿轮 534, 所述输出端传动杆 533外端与传动轴 54的第二段传动连接而内端设置有第二锥齿轮 535 , 在所述第 一锥齿轮 534和第一传动齿轮 530之间还设置有分别与第一锥齿轮 634和第一传动 齿轮 530啮合的第三传动齿轮 536， 在所述第二锥齿轮 535和第二传动齿轮 531之 间还设置有分别与第二锥齿轮 535和第二传动齿轮 531啮合的第四传动齿轮 537， 所述第三传动齿轮 536和第四传动齿轮 537均为由锥齿轮和直齿轮共轴组合而成 的复合齿轮。 本实施例将第一卷轴 522和第二卷轴 524的轴向设置为与传动轴垂 直， 为此对应设置了相应的锥齿轮传动机构来实施动力方向的转换， 而仍然可 以实现驱动第一卷轴 522旋转以及将动力从平面渦卷弹簧机构 52的另一端将动力
传递至另一端的传动轴 54上。
[0035] 在本发明又一个可选实施例中， 所述平面渦卷弹簧 526是由常规工艺制成的传 统平面渦卷弹簧进行反向绕卷而成的， 所述平面渦卷弹簧的簧片的工作段的成 型曲率半径由外圈向内圈逐渐增大。 应当理解的是， 本发明实施例中提及的簧 片工作段是指帘体 2从完全闭合的初始位置运动到帘体 2完全打开的过程中受力 的簧片段， 此外， 本发明实施例中所提及的外圈和内圈均是相对的概念， 即相 对而言， 离轴心远的为外圈， 离轴心近的为内圈， 以位于中间层的簧片为例， 其相对于位于其外侧的簧片即为内圈， 而相对于位于其内侧的簧片即为外圈。 本实施例通过采用常规工艺制成的传统平面渦卷弹簧进行反向绕卷制得新型的 平面渦卷弹簧 526 , 使得簧片工作段的成型曲率半径由外圈向内圈逐渐增大， 而 使得本实用新型实施例提供的平面渦卷弹簧外圈提供的扭矩大于其内圈提供的 扭矩， 对应地， 外圈的簧片起作用时帘体所需的支撑力也较大， 内圈的簧片起 作用时帘体所需的支撑力较小， 从而， 使得平面渦卷弹簧的扭矩分布与帘体所 需的支撑力更好地相匹配， 始终能给帘体所需要的有效支撑力。
[0036] 在本发明又一个可选实施例中， 所述平面渦卷弹簧 526的簧片包括至少两个等 矩段以及衔接于相邻两等矩段之间的作为工作段的变矩段， 所述变矩段内各处 的簧片的成型曲率半径由外圈向内圈逐渐增大， 而等矩段内各处的簧片的成型 曲率半径相等。 本实施例通过设计至少两个等矩段及对应的变矩段， 从而可以 在平面渦卷弹簧卷绕到不同区段时具有不同变化的扭矩， 更能符合不同窗帘产 品的设计需求。
[0037] 尽管已经示出和描述了本发明的实施例， 对于本领域的普通技术人员而言， 可 以理解在不脱离本发明的原理和精神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， 本发明的范围由所附权利要求及其等同范围限定。
