具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1示意性地显示了根据本申请的一个实施例的扇叶限位结构，扇叶限位结构包括风扇盘100、扇叶200和限位槽300，风扇盘100可绕其中心转动，多个扇叶200沿风扇盘100的周向设置，扇叶200交接与风扇盘100上，以使扇叶200能够张开或者收拢于风扇盘100上，限位槽300设置在风扇盘100上，且沿扇叶200的转动方向延伸，扇叶200上设置有能够沿限位槽300滑动的滑动部210。限位槽300具有相对的第一端和第二端，第一端和所述第二端不相接。
具体的，风扇盘100的中心可设置转轴，转轴被电机所驱动，从而使得风扇盘100整体能够转动，扇叶200设置在风扇盘100上后能够随着风扇盘 100转动而转动，扇叶200在随着风扇盘100转动的过程中受离心力作用扇叶200还会绕着其与风扇盘100的铰接处转动，与此同时，离心力能够让扇叶200上的滑动部210始终与限位槽300的一个端部抵接，达到对扇叶200固定的作用，当需要收拢扇叶200时，转动扇叶200使滑动部210转动至限位槽300的另一端部并与限位槽300的此端部抵接，以达到对扇叶200限位的作用。限位槽300的第一端和第二端不相接，能够限制扇叶200绕其铰接处转动的角度，第一端和第二端起到对扇叶200转动角度限位的作用。
在一个实施例中，如图1和图5所示，当滑动部210位于第一端时，多个扇叶200的外周尺寸不大于风扇盘100的外径，当滑动部210位于第二端时，多个扇叶200的外周尺寸相对最大。
扇叶200在转动过程中，扇叶200受到离心力影响而绕其与风扇盘100的铰接点转动，当滑动部210转动至第二端时，第二端对滑动部210能够阻止扇叶200继续转动，此时扇叶200张开后的外周尺寸为最大尺寸，而需要收拢扇叶200时，通过转动扇叶200，使滑动部210移动至第一端，第一端对滑动部210限位，此时扇叶200处于收拢的状态，并且扇叶200外周尺寸不大于风扇盘100，使本扇叶200收拢时外观美观简洁。
在一个实施例中，上述的限位槽300靠近扇叶200与风扇盘100的连接处设置，且限位槽300绕扇叶200和风扇盘100的连接处周向设置，这样能够使风扇盘100具有更大的空间安装其他部件，同时也能够减小滑动部210所占用的风扇盘100上的空间。
在一个实施例中，如图1和图2所示，扇叶200与风扇盘100的连接处靠近风扇盘100的边缘，这样当扇叶200张开后其能够外周范围更大，相应的，转动后所形成的风力也更大。
在一个实施例中，如图4所示，滑动部210为一轴部，滑动部210沿限位槽300滑动过程中始终与限位槽300的内壁接触。因此，限位槽300的宽度应始终与滑动部210的外径配合，以使上述两者始终处于贴合状态。滑动 部210的壁面为弧面，在滑动过程中与限位槽300的内壁接触更为顺滑。
在一个实施例中，如图3和图4所示，限位槽300的槽口310的宽度小于槽本体320的宽度，滑动部210上具有直径小于滑动部210的内凹部211，内凹部211嵌入限位槽300的槽口310，以使滑动部210固定在限位槽300内。
当内凹部211容置于槽口310时，内凹部211的上下两端与限位槽300的槽口310相干涉，从而能够使滑动部210固定于限位槽300内，从而防止滑动部210在滑动过程中脱离限位槽300。
为了使具有内凹部211的滑动部210能够安装于限位槽300内，本实施例还具有与限位槽300的连通的安装槽，安装槽的槽口大小与滑动部210配合，以使滑动部210能够深入至安装槽内，具体的，在安装滑动部210时，可通过将滑动部210先插入至安装槽内后再将滑动部210转动至限位槽300内。从而使得滑动部210安装方便。
在一个实施例中，如图1和图2所示，扇叶200具有相连接的第一叶部220和第二叶部230，其中，第一叶部220靠近扇叶200与风扇盘100的连接处，第二叶部230远离扇叶200与风扇盘100的连接处，第二叶部230与风扇盘100之间的间距大于第一叶部220与风扇盘100之间的间距。
为了使扇叶200的面积设置的更大，在扇叶200处于收拢状态下相邻的扇叶200应重叠设置，因此某一个扇叶200的第二叶部230应该盖合在相邻扇叶200的第一叶部220上，因此将第二叶部230与风扇盘100之间的间距设置为大于第一叶部220与风扇盘100之间的间距。
在一个实施例中，如图5所示，扇叶200处于收拢状态下其靠近风扇盘100边缘处的一侧与风扇盘100的边缘对齐，扇叶200与风扇盘100边缘对齐能够使扇叶200收拢时隐藏于风扇盘100上的同时具有相对更大的表面积，从而使扇叶200转动所产生的风力更强。
在一个实施例中，如图1所示，风扇盘100上设置有加强筋，加强筋能 够使风扇盘100的结构强度更高。
本申请还提供一种风扇灯，如图6所示，包括上述的扇叶限位结构和照明部400，其中，照明部400设置在风扇盘100背离扇叶200的端面上。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
