下面参考图1-图9描述根据本发明实施例的用于风扇的驱动组件100。
如图1-图9所示，根据本发明实施例的用于风扇的驱动组件100，包括：电机支架1、第一驱动电机2、球形曲柄4和第二驱动电机3。
具体而言，如图1、图2、图4和图5所示，球形曲柄4包括连接柱41和球头42，连接柱41的一端与第一驱动电机2的输出轴连接，球头42设在连接柱41的另一端且球头42的球心与连接柱41的旋转轴线之间具有预定距离，该预定距离大于零。球形曲柄4为一个曲柄结构。如图1、图2和图3所示，第二驱动电机3设在电机支架1上且与第一驱动电机2间隔开，第二驱动电机3具有第一端31和第二端32，第二端32与球头42可转动的连接，第二驱动电机3的输出轴设在第一端31，第二驱动电机3的输出轴与扇叶200连接。
第一驱动电机2工作，第一驱动电机2的输出轴转动可带动连接柱41转动，球头42可以绕连接柱41的转动轴线旋转，从而带动第二驱动电机3的第二端32绕连接柱41的转动轴线360°旋转，第二驱动电机3的输出轴在电机支架1的支撑作用下绕连接柱41的转动轴线360°旋转，进而带动扇叶200绕连接柱41的转动轴线360°旋转。同时第二驱动电机3可以驱动扇叶200绕其旋转轴线转动。由此，不但可以使扇叶200绕其转动轴线转动，还可以使扇叶200实现绕连接柱41的转动轴线360度旋转，让扇叶200送风形成螺旋式，从而扩大送风范围，提升送风速度和送风距离，满足用户的舒适度。
根据本发明实施例的用于风扇的驱动组件100，通过设置第一驱动电机2和球形曲柄4，使球形曲柄4的一端与第一驱动电机2的输出轴连接，球头42与第二驱动电机3的第二端32可转动地连接，当第一驱动电机2工作时，可以实现第二驱动电机3及与第二驱动电机3的输出轴连接的扇叶200绕连接柱41的转动轴线360°旋转，从而可以扩大送风范围，提升送风速度和送风距离，满足用户的舒适度。
在本发明的一些实施例中，如图2、图3和图7所示，驱动组件100还包括球形关节轴承5，球形关节轴承5设在电机支架1上且套设在第二驱动电机3的输出轴上。由此便于第二驱动电机3的输出轴相对电机支架1绕连接柱41的转动轴线360°旋转，减小电机支架1对第二驱动电机3的输出轴的磨损，从而提高第二驱动电机3工作的可靠性。
进一步地，如图2和图3所示，电机支架1上设有卡合槽111，卡合槽111为弧形槽，球形关节轴承5卡设在卡合槽111内。卡合槽111可以对球形关节轴承5起到固定的作用， 防止球形关节轴承5在风扇工作过程中从电机支架1上脱落，从而提高驱动组件100工作的可靠性，进而提高风扇工作的可靠性。
在本发明的一些实施例中，如图2和图4所示，驱动组件100还包括第一连接板6，第一连接板6与第二端32连接，例如，第一连接板6可以与第二端32通过螺纹紧固件连接，第一连接板6的背向第二驱动电机3的一侧，即第一连接板6朝向球形曲柄4的一侧，设有与球头42配合的球套61。球头42可以在球套61内转动，且可以360°转动，由此便于实现球形曲柄4与第二驱动电机3的可转动地连接，便于球形曲柄4驱动第二驱动电机3绕连接柱41的转动轴线360°旋转。另外，当球形曲柄4与秋涛61进行装配时，球头42可以直接压入球套61内，并卡设在球套61内。
在本发明的一些实施例中，如图2、图3和图6所示，驱动组件100还包括第二连接板7，第二连接板7与第一端31连接，例如，第二连接板7可以与第二驱动电机3的第一端31通过螺纹紧固件连接。第二连接板7的背向第二驱动电机3的一侧，即第二连接板7朝向扇叶200的一侧，设有中心柱71，中心柱71的横截面为圆形，中心柱71上设有沿其长度方向延伸的通孔711以供第二驱动电机3的输出轴穿过，球形关节轴承5套设在中心柱71的外表面上。由此便于第二驱动电机3的输出轴与球形关节轴承5的配合，从而提高驱动组件100工作的可靠性。
进一步地，如图6所示，中心柱71的外周壁上设有沿其周向方向延伸的卡槽73。如图2、图3和图8所示，驱动组件100还包括卡簧74，卡簧74适于卡设在卡槽73内以将球形关节轴承5限定在第二连接板7和卡簧74之间。由于球形关节轴承5设在电机支架1上，将球形关节轴承5限定在第二连接板7和卡簧74之间，可以保证第二驱动电机3和球形关节轴承5之间的相对位置，便于第二驱动电机3的输出轴与球形关节轴承5的配合，从而便于实现第二驱动电机3带动扇叶200绕连接柱41的转动轴线360°旋转，从而可以扩大送风范围，提升送风速度和送风距离，满足用户的舒适度。
更进一步地，如图8所示，卡簧74呈圆弧状，圆弧状的卡簧74具有开口，便于卡设在卡槽73内。具体地，该圆弧所对应的圆心角大于180°，由此可以避免卡簧74从卡槽73内脱落。再进一步地，卡簧74的内周壁上设有至少一个凹槽741，卡簧74在凹槽741处易发生变形，由此便于将卡簧74卡设到卡槽73内，且便于从卡槽73内取出。
在本发明的一些实施例中，如图2、图6和图7所示，第二连接板7上设有定位柱72，球形关节轴承5上设有固定部51，固定部51与球形关节轴承5的内圈连接，固定部51上设有与定位柱72配合的定位孔511。定位柱72可以伸入定位孔511内，当第二驱动电机3的输出轴与球形关节轴承5配合时，即第二连接板7上的中心柱71与球形关节轴承5配合 时，定位柱72伸入到定位孔511内，可以保证第二连接板7与球形关节轴承5之间配合的可靠性，从而保证第二驱动电机3的输出轴与球形关节轴承5之间配合的可靠性。
在本发明的一些实施例中，如图9所示，扇叶200旋转时所形成的理论气流柱的最外缘与扇叶200的旋转中心轴线的夹角定义为风扩散角R，所述R满足：0°＜R≤45°。由此，可以扩大送风范围，满足用户的舒适度。
在本发明的一些实施例中，驱动组件100还包括橡胶套，橡胶套套设在球形关节轴承5的外周壁上。由此可以减小驱动组件100工作过程中的振动，提高驱动组件100工作的可靠性。
在本发明的一些实施例中，如图1和图2所示，驱动组件100还包括前外壳8，前外壳8与电机支架1连接，第二驱动电机3的输出轴穿过前外壳8与扇叶200连接。前外壳8可以增加驱动组件100的外观的美观性，同时可以防止向驱动组件100上落尘。
在本发明的一些实施例中，驱动组件100还包括网罩索母9，网罩索母9位于前外壳8的远离电机支架1的一侧，网罩索母9与前外壳8螺纹连接，第二驱动电机3的输出轴穿过前外壳8和网罩索母9与扇叶200连接。网罩索母9用于将扇叶200的出风框限定在前外壳8与网罩索母9之间，起到固定出风框的目的。

如图2和图3所示，第一安装板11上设有半圆形的卡合槽111，与中心柱71配合后的球形关节轴承5适于卡合在卡合槽111内实现球形关节轴承5的固定，从而实现第二驱动电机3的固定。
