Description

窗帘绕线轮驱动机构 技术领域
[0001] 本发明创造实施例涉及绕线轮驱动机构技术领域， 尤其涉及一种窗帘绕线轮驱 动机构。
背景技术
[0002] 窗帘是一种常见的现代家居、 办公室装饰用品， 传统的窗帘通常有拉绳来控制 窗帘的收放， 拉绳一端绕设于窗帘收放线装置的绕线轮， 窗帘收放线装置中的 绕线轮驱动机构通过驱动绕线轮旋转以缠绕拉绳进而达到收放窗帘的目的。
[0003] 现有的绕线轮驱动机构通常采用弹性件以驱动绕线轮旋转， 以手动拉弓 I拉绳收 起窗帘为例， 手动拉引拉绳使绕线轮正向旋转收起拉绳， 而绕线轮的旋转亦会 带动绕线轮驱动机构中与绕线轮共轴连接的滚轮正向旋转， 进而使得与滚轮连 接的弹性件发生形变， 绑定拉绳于预设位置即可实现窗帘的收起； 当想要将窗 帘放下吋， 通过放松拉绳使得滚轮在弹性件的弹性作用下逆向旋转进而带动绕 线轮逆向旋转使拉绳从绕线轮上绕出， 即可实现窗帘的放下。
[0004] 但是， 现有的绕线轮驱动结构通常只是配置单一的弹性件以驱动绕线轮旋转， 在窗帘较重的情况下， 单一的弹性件的弹性作用不足以实现窗帘的收放， 而通 过配置有多个绕线轮驱动机构又难以协调所有绕线轮驱动机构的一致性， 增加 绕线轮驱动机构的组装难度。

[0029] 在一个可选实施例中， 所述绕线轮驱动机构包括两个或两个以上的驱动模块 1 ， 全部驱动模块 1依次插接相连形成长条状的驱动模块组， 依次插接的各驱动模 块 1均以中转轴 13第二端的第一凸轴 132插接于前端相邻的驱动模块 1的中转轴 13 第一端的第一轴孔 131内， 而位于驱动模块组最前端的一个驱动模块 1以中转轴 1 3第二端的第一凸轴 132对应插入第二过渡轴 3的第二轴孔 31内， 位于驱动模块组 最后端的一个驱动模块 1以中转轴 13第一端的第一轴孔 131供第一过渡轴 2的第二 凸轴 21插入。
[0030] 本实施例通过设有两个或两个以上的驱动模块 1依次插接相连形成长条状的驱 动模块组， 所述驱动模块组包括由多个中转轴 13依次插接组装成长条状的中转 轴组合体以及多个连接至中转轴组合体中各个中转轴 13上以同步驱动中转轴组 合体旋转的动力件 12， 通过多个动力件 12共同作用于中转轴 13以增强对中转轴 组合体的驱动力， 从而增强驱动机构的卷绕力， 进而实现对不同规格的窗帘的 收放， 能有效提高驱动机构的实用性。
[0031] 在一个可选实施例中， 所述基座 11两侧还设有与基座 11形成限位空间 15以对所 述第一过渡轴 2和第二过渡轴 3进行限位的端盖 16， 所述端盖 16设有供所述第一 过渡轴 2和第二过渡轴 3自限位空间 15伸出的过孔 161， 所述第一过渡轴 2和第二 过渡轴 3位于限位空间 15—端均设有凸环 17且所述凸环 17的外径大于过孔 161的 内径。
[0032] 本实施例通过基座 11与端盖 16组装形成相位空间 15以实现对第一过渡轴 2和第 二过渡轴 3的限位和组装， 所述第一过渡轴 2和第二过渡轴 3—端穿过端盖 16的过 孔 161且位于限位空间中的另一端均设有外径大于过孔 161内径的凸环 17， 能有 效提高端盖 16对第一过渡轴 2和第二过渡轴 3的组装结构强度， 提高驱动机构的 稳定性。
[0033] 在一个可选实施例中， 所述端盖 16通过螺丝 （图未示出） 锁固与基座 11外表面 。 本实施例通过采用螺丝将端盖 16组装于基座 11的外表面， 通过取下螺丝即可 将端盖 16从基座 11上卸下进而实现对第一过渡轴 2和第二过渡轴 3的保养和维修
， 结构简单可靠。
[0034] 在一个可选实施例中， 所述基座 11为设有中空腔室 （图未标号） 的壳体， 所述 动力件 12和中转轴 13均安装与所述中空腔室内。
