具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
如图1所示，根据本发明的实施例，导风板驱动装置包括第一驱动电机20、与第一驱动电机20固定连接的连接结构，还包括连接在第一驱动电机20的输出轴与导风板10之间的传动部30，传动部30包括第一传动件31和第二传动件32，第一传动件31固定设置在第一驱动电机20的输出轴上，并随输出轴一起转动；第二传动件32与导风板10固定连接，并在第一传动件31的驱动下运动。第一驱动电机20与导风板10之间通过第一传动件31和第二传动件32连接，可以避免第一驱动电机20直接装配到导风板10上的间隙，提高装配精度，进而能够避免导风板10运动过程中的抖动。
导风板驱动装置还包括第二驱动电机，第二驱动电机固定设置在壳体上。连接结构可移动地设置在壳体内，并具有位于壳体外的推出位置和位于壳体内的闭合位置，连接结构在第二驱动电机的驱动下在推出位置与闭合位置之间运动。
为了提升美观性，应尽量减小导风板10闭合时与壳体之间的间隙，但若间隙过小将会使得壳体干涉导风板10的运动，为了解决这一问题，通过连接结构连接在壳体与导风板10之间，工作时，先通过第二驱动电机驱动连接结构从壳体内伸出，使连接结构带动导风板10运动到推出位置，继而通过第一驱动电机20驱动导风板10运动到合适的导风角度，这样既可以保证闭合时导风板10与壳体间无间隙，提升美观度，又能够时导风板10具有足够大的导风角度，提升导风效果。
结合参见图3和4，在本实施例中，连接结构为连接杆40，连接杆40包括电机连接端41和齿条结构42。其中电机连接端41固定连接在第一驱动电机20的远离输出轴的一端，用于固定第一驱动电机20。齿条结构42位于连接杆40的侧壁上，并与第二驱动电机配合，第二驱动电机与齿条结构42之间通过齿啮合的方式传动，传动精度高。优选地，齿条结构42为弧形齿条结构。
优选地，连接杆40上还设置有弧形导向槽43，弧形导向槽43的弧形与弧形的齿条结构42的弧形同心，壳体上设置有与弧形导向槽43配合的导轮。通过弧形导向槽43与导轮的配合可以保证弧形的齿条结构42始终处于与第二驱动电机啮合的状态，同时能够保证连接杆40的运动平稳，避免导风板10抖动。
在其它实施例中，连接杆40上可以不设置弧形导向槽43，而通过连接杆40的下壁面与导轮配合实现对连接杆40的定位和导向，此种情况下，连接杆40的下壁面为弧形壁面，且该弧形壁面的圆心与弧形的齿条结构42的圆心重合。
结合参见图2，在本实施例中，第一传动件31为固定设置在第一驱动电机20的输出轴上的第一传动齿轮，第二传动件32与第一传动齿轮齿啮合传动。第二传动件32可以为第二传动齿轮，第二传动齿轮与第一传动齿轮啮合，且第二传动齿轮与导风板10固定连接。第二传动件32也可以为与第一传动齿轮齿啮合的弧形齿条，该弧形齿条的弧形与导风板10的转动轨迹相同，该弧形齿条固定连接在导风板10上。第一传动齿轮与第二传动齿轮之间可以通过改变齿数比调节导风板10的转动速度，进而提高导风板10的适用性。在本实施例中，第二传动齿轮的齿数大于第一传动齿轮的齿数，这样可以缩小电机的转速，同时第一传动齿轮与第二传动齿轮啮合的方式可以吸收第一驱动电机20的失步，进而避免导风板10抖动。
在本实施例中，导风板10朝向空调壳体内的一侧设置有安装耳板11，安装耳板11上安装有十字接头齿轮轴111，第二传动齿轮固定设置在十字接头齿轮轴111上。十字接头齿轮轴111与安装耳板11之间连接稳固且间隙小，能够进一步减小间隙，进而避免导风板10抖动。
优选地，导风板10朝向壳体的一侧设置有止挡凸起12，第一驱动电机20位于止挡凸起12与第二传动件32之间。止挡凸起12能够保证第一驱动电机20上的第一传动齿轮与第二传动齿轮始终处于啮合状态。
根据本发明的另一方面，空调器具有壳体，壳体包括导风板10，空调器还包括导风板驱动装置，导风板驱动装置为上述的导风板驱动装置。
导风板10的一侧设置有该导风板驱动装置，导风板10的另一侧还有另一个安装耳板，该安装耳板与另一连接杆40铰接，保证连接杆40与导风板10之间的连接稳固。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：通过第一传动齿轮和第二传动齿轮可以将减小导风板与第一驱动电机之间的间隙，避免导风板抖动。通过改变第一传动齿轮与第二传动齿轮之间的齿数比可以放大或缩小导风板的运动速度。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
