本公开要求于2019年12月6日提交中国专利局、申请号为201911246642.9、发明名称为“风扇摇头机构及具有其的风扇”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及家用电器技术领域，具体涉及一种风扇摇头机构及具有其的风扇。
背景技术
现有风扇摇头机构多为依靠底部的单向同步电机通过平面四连杆推动机体运动，此种结构组成部件一般有同步电机、曲柄、连杆、摇杆、支撑板、压板、固定板、轴套、卡簧等。
但是，上述的摇头机构零件种类多，结构复杂，组装效率低，且曲柄连杆结构作为驱动结构时，作用点单一，导致风扇的某一部位受力集中，且应力集中处多位于偏心位置，导致机身的稳定性差。
发明内容
因此，本公开要解决的技术问题在于克服相关技术中风扇摇头机构复杂且易导致风扇稳定性差的缺陷，从而提供一种风扇摇头机构、风扇。
为了解决上述问题,本公开提供了一种风扇摇头机构包括：基座；转动组件，可转动地设置在所述基座上，所述转动组件包括：连接件，设置在风扇机身上；滚动组件，设置在所述连接件上，其滚动端嵌装在所述基座上；以及驱动组件，设置在所述基座和/或所述转动组件上，以驱动所述转动组件发生转动。
在一些实施方式中，所述转动组件还包括环绕所述基座设置的限位圈，所述限位圈的一端设置在所述连接件上，一端活动卡接在所述基座上。
在一些实施方式中，所述限位圈的下端面边沿具有朝向所述限位圈中心设置的挡边，沿所述基座的周向向外设置有凸边，所述挡边卡接在所述凸边下方。
在一些实施方式中，所述限位圈的上端面处设置有若干个卡勾和/或勾槽，所述连接件上对应设置有所述勾槽和或卡勾。
在一些实施方式中，所述滚动组件包括：保持架，其上设置有若干卡槽；滚珠，所述滚珠的部分活动设置在所述卡槽内。
在一些实施方式中，所述卡槽具有圆形的槽孔以及至少一对相对设置在所述槽孔内壁上的弹性限位件。
在一些实施方式中，所述保持架呈圆环状，若干个所述卡槽沿其周向等间隔分布。
在一些实施方式中，所述滚动组件包括衬圈，所述保持架设置在所述衬圈的下端面。
在一些实施方式中，所述衬圈朝向所述衬圈中心处成型有围圈，所述保持架嵌装在所述围圈内。
在一些实施方式中，所述围圈的外周面上设置有止动结构。
在一些实施方式中，所述连接件的下端面处和所述基座的上端面处均成型有与所述衬圈适配的环形槽，所述衬圈被卡付在所述连接件的环形槽内。
在一些实施方式中，所述滚珠凸出所述保持架的部分抵接在所述基座的环形槽的槽底。
在一些实施方式中，所述驱动组件包括：电机，设置在所述连接件的下端面上；主动齿轮，设置在所述电机的电机轴上；从动齿，设置在所述基座上，与所述主动齿轮啮合。
在一些实施方式中，所述从动齿为成型在所述基座内侧壁上的齿圈。
本公开还提供了一种风扇包括上述任一所述的风扇摇头机构；机身，设置在连接件上；以及底座，设置在所述基座的下端面上。
本公开技术方案，具有如下优点：
1.本公开中的风扇摇头机构包括：基座；转动组件，可转动地设置在所述基座上，所述转动组件包括：连接件，设置在风扇机身上；滚动组件，设置在所述连接件上，其滚动端嵌装在所述基座上；以及驱动组件，设置在所述基座和/或所述转动组件上，以驱动所述转动组件发生转动。
需要阐述的是，基座一般与风扇的底盘固定连接，转动组件通过连接件固定在风扇机身上，滚动组件的滚动端嵌装在基座上，在基座上做滚动，在驱动组件驱动转动组件时，风扇机身可在滚动组件的作用下，在基座上转动。本公开中的转动组件采用滚动组件实现风扇机身与基座间的活动连接，滚动组件在机身高度方向实现对机身的支撑作用，一般滚动支撑的支撑点均设为多个，支撑的稳定性好，另，在风扇机身的径向上，滚动组件以嵌装的方式设置在基座上，实现了对滚动组件径向上的约束，进一步保证了转动过程中的稳定性。
进一步对结构复杂度作出阐述：背景技术中简单罗列了现有的平面四连杆机构的组成包括同步电机、曲柄、连杆、摇杆、支撑板、压板、固定板、轴套、卡簧等零件多达13种以上，更重要的是，在各活动连杆连接处需要使用卡簧、防脱环、轴套，卡簧和防脱环体积小，且是卡接，拆装费时费力，本公开中的结构主要是基座、连接件、滚动组件和驱动组件，零件数量少，且未使用卡簧、防脱环等拆装费力的零件，降低了结构复杂度以及组装的难度。
2.本公开中的风扇摇头机构中所述转动组件还包括环绕所述基座设置的限位圈，所述限位圈的一端设置在所述连接件上，一端活动卡接在所述基座上。因风扇机身具有相当的高度，为了减少滚动组件与基座卡装处的径向应力，保证滚动组件的使用寿命，本公开设置了限位圈，间接护持在滚动组件的周向上，部分活动卡装罩设在基座上，以减少机身在转动过程中相对基座外周发生的晃动。
3.本公开中的风扇摇头机构中所述限位圈的下端面边沿具有朝向所述限位圈中心设置的挡边，沿所述基座的周向向外设置有凸边，所述挡边卡接在所述凸边下方，本公开中以挡边与凸边上下设置的关系，实现了对其机身高度方向上的约束，如在上提风扇整机时，挡边抵接凸边，为底盘组件与风扇机身提供连接作用力，在周向方向上，整个挡边结构实现对凸边的部分包覆，约束了其径向上的移动。
4.本公开中的风扇摇头机构中所述限位圈的上端面处设置有若干个卡勾，所述连接件上与所述卡勾对应设置有勾槽，卡勾和勾槽的方式，在安装时，转动限位圈即可将卡勾卡装在勾槽内，安装简单快捷。
5.本公开中的风扇摇头机构中所述滚动组件包括：保持架，其上设置有若干卡槽；滚珠，所述滚珠的部分活动设置在所述卡槽内，本公开中将实现滚动的结构设置为滚珠，一方面滚珠的支撑数量多，支撑效果好，另一方面，滚珠在滚动时，摩擦阻力小，可减少转动的噪音以及对驱动组件的负载。
6.本公开中的风扇摇头机构中所述卡槽具有圆形的槽孔以及至少一对相对设置在所述槽孔内壁上的弹性限位件，弹性限位件实现了滚珠的卡装，其同时不会影响到滚珠在槽孔中的转动，有效解决了滚珠在安装过程中容易从槽孔中脱落丢失的问题，降低了对滚动组件的组装难度。
7.本公开中的风扇摇头机构中所述保持架呈圆环状，若干个所述卡槽沿其 周向等间隔分布，卡槽的等间隔分布，安装在其上的滚珠必然等间隔分布，上述分布方式，可对风扇机身起到更好的支撑效果，支撑的稳定性更好。
8.本公开中的风扇摇头机构中所述滚动组件包括衬圈，所述保持架设置在所述衬圈的下端面，因滚珠直接抵接在连接件上的话，连接件多为注塑件，强度低，时间久了，因连接件抵接位置的变形，易导致滚珠滚动不顺畅，产生噪音等，衬圈的设置将滚珠抵接在衬圈上，可有效解决上述问题。
9.本公开中的风扇摇头机构中所述围圈的外周面上设置有止动结构，通过止动结构实现了将整个转动组件固定在连接件上，结构简单，安装方便。
10.本公开中的风扇摇头机构中所述连接件的下端面处和所述基座的上端面处均成型有与所述衬圈适配的环形槽，所述衬圈被卡付在所述连接件的环形槽内，环形槽的设置可约束衬圈，以及转动组件在径向上的移动，进一步地减少机身在转动时的晃动，增加稳定性。

实施例1
图1到图7所示，为本实施例提供的一种风扇摇头机构，包括：基座1；转动组件2，可转动地设置在基座1上，转动组件2包括连接件21，设置在风扇机身上；滚动组件22，设置在连接件21上，其滚动端嵌装在基座1上；以及驱动组件3，设置在基座1和/或转动组件2上，以驱动转动组件2发生转动。
本实施例中的风扇摇头结构安装在风扇的机身和底盘之间，以使风扇的机身可在底盘上发生转动。
需要阐述的是，基座1一般与风扇的底盘固定连接，转动组件2通过连接件21固定在风扇机身上，滚动组件22的滚动端嵌装在基座1上，在基座1上做滚动，在驱动组件3驱动转动组件2时，风扇机身可在滚动组件22的作用下，在基座1上转动。本实施例中采用的转动组件2中采用滚动组件22实现风扇机身与基座1间的活动连接，滚动组件22在机身高度方向实现对机身的支撑作用，一般滚动支撑的支撑点均设为多个，支撑的稳定性好，另，在风扇机身的径向上，滚动组件22以嵌装的方式设置在基座1上，实现了对滚动组件22径向上的约束，进一步保证了转动过程中的稳定性。
在一些实施方式中，本实施例中的风扇摇头结构的实施对象多为塔扇或无叶风扇，其机身多为圆柱状，故本实施例中的风扇摇头结构的整体形状为圆盘 状，与机身相匹配，以保证风扇整体结构的美观性。
本实施例在进行整体组装前，需要先将转动组件2进行预组装，下面对转动组件2进行阐述：
如上所述，转动组件2其中包括有滚动组件22，在对转动组件2进行组装时，先组装滚动组件22，其中滚动组件22包括滚动组件22包括：保持架221，其上加工有若干卡槽2211，本实施例中为十个，且如图5和图6中给出的示例，卡槽2211为通槽。当然在其他实施方式中，也可为其他数量个，数量越多，起到的支撑效果越好。滚珠222，滚珠222的部分活动安装在卡槽2211内，滚珠222的使用，可减少风扇机身转动时的摩擦阻力以及噪音。
在其他的一些实施方式中，上述的滚动组件22中的滚珠222也可被替换为滚轮结构，滚轮的轴端安装在保持架221上，其安装方式如常用的滚轴安装方式类似，在此不作赘述。
在一些实施方式中，上述地卡槽2211具有圆形的槽孔以及至少一对相对设置在槽孔内壁上的弹性限位件，本实施例中如图5和图6中所示，在卡槽2211的内壁上，沿整个保持架221的周向一面上安装有两个弹性限位件2212，且沿着保持架221的径向的另一面上亦安装有两个弹性限位件2212，上述共四个弹性限位件2212形成十字排布的滚珠222卡付空间，滚珠222被可转动地卡装在四个弹性限位件之间，在滚珠222实际安装的时候，其极易从卡槽2211中脱落，移动以及和其他部件的组合安装都较为费力，以致需要设计相应的安装治具，费时费力，弹性限位件的设计有效简化了滚珠222的安装。
在其他一些实施方式中，弹性限位件2212的数量也可为六个、八个等，其对滚珠222的卡装效果更好。
在其他一些实施方式中，弹性限位件的数量也可为奇数个，如三个等，同样可实现对滚珠222的卡装。
在其他一些实施方式中，上述的弹性限位件2212也可仅布置在保持架221的单面上，数量上与双面布置的方式类似。
本实施例中的保持架221呈圆环状，上述的卡槽2211沿其周向等间隔分布，这样布置在其上的每个滚珠222的承受力的大小基本相同，不会出现因分力不均匀导致部分滚珠222受力过大，出现提前损毁的情况，进一步地保证了支撑的稳定性。
本实施例中的连接件21多为注塑件，强度低，滚珠222直接抵接在连接件21上的话，时间久了，连接件21抵接位置的变形，易导致滚珠222滚动不顺畅，产生噪音等，故在本实施例中滚动组件22包括衬圈223，保持架221安装在衬圈223的下端面。
在一些实施方式中，衬圈223朝向衬圈223中心处成型有围圈，保持架221以间隙配合的方式嵌装在围圈内。在实际的转动过程中，滚珠222在使用过程中异常状态下可能发生间歇性卡死，间隙配合安装在围圈内的保持架221在滚珠222卡死时，可自行在围圈内滑动，不影响风扇摇头机构的工作。
当然，在确保滚珠222可良好地在卡槽2211中转动时，在一些其他的实施方式中，保持架221亦可以过盈配合的方式嵌装在围圈内。
因在实际的转动过程中，衬圈223是不需要转动的，因此在围圈的外周面上成型有止动结构，上述的止动结构为凸出上述外周面的小凸边，安装时，将上述凸边结构，嵌入到连接件21上的安装槽内即可防止其发生转动。
如图7中所示，因风扇机身具有相当的高度，为了减少滚动组件22与基座1卡装处的径向应力，保证滚动组件22的使用寿命，本实施例中还设计了环绕基座1安装的限位圈23，限位圈23的一端安装在连接件21上，一端活动卡接在基座1上，限位圈23护持在滚动组件22的周向上，部分活动卡装罩设在基座1上，以减少机身在转动过程中相对基座外周发生的晃动。
其卡装方式如下，限位圈23的下端面边沿具有朝向限位圈23中心成型的挡边231，沿基座1的周向向外成型有凸边11，挡边231卡接在凸边11下方。挡边231与凸边11上下设置的关系，实现了对其机身高度方向上的约束，在周向方向上，整个挡边231结构实现对凸边11的部分包覆，约束了其径向上的移动。
为了实现对限位圈23的固定，在限位圈23的上端面处成型有三个卡勾232，连接件21上与卡勾232对应成型有勾槽，在安装时，转动限位圈即可将卡勾232卡装在勾槽内，安装简单快捷。
当然，在其他一些实施方式中，卡勾232亦可加工在连接件21上，卡槽加工在限位圈23上。
为了进一步地约束在径向上的晃动，连接件21的下端面处和基座1的上端面处均成型有与衬圈223适配的环形槽，衬圈223被卡付在连接件21的环形槽内。
当然，为了保证转动组件2的顺畅转动，滚珠222凸出保持架221的部分抵接在基座1的环形槽的槽底。
下面对驱动组件3进行简单的介绍，如图1所示，驱动组件3包括：电机31，安装在连接件21的下端面上；主动齿轮32，以平键的方式安装在电机31的电机轴上；从动齿33，设置在基座1上，与主动齿轮32啮合，如图3中所示，从动齿33为成型在基座1内侧壁上的齿圈。
当然在其他一些实施方式中，上述的齿圈也可为外齿圈的设置方式，能实现齿轮的基本传动即可。
实施例2
如图8所示，为本实施例提供的一种风扇，包括：任一所述的风扇摇头机 构；机身4，以螺钉锁付在连接件21上；以及底座5，以螺钉锁付和/或旋转卡付在所述基座1的下端面上，其因上述摇头结构的使用，可有效的解决风扇机身4在转动过程中的稳定性问题。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本公开创造的保护范围之中。
