第二齿条结构300用于推出导风板400，并带动导风板400旋转，第二齿条结构300包括第二本体301、第四导向结构310、第五导向结构320和第二齿部330。第二本体301为折弯结构，包括3011主体结构和连接结构3012，3011主体结构的一端与连接结构3012向上折弯连接，连接结构3012的端部设置有转轴302，转轴302与导风板400的调向轨道槽420配合，转轴302可以在调向轨道槽420内旋转，并可沿调向轨道槽420移动。当转轴302在沿调向轨道槽420的槽体移动时，转轴302带动导向板绕旋转轴430转动。
第四导向结构310位于第二本体301的第一表面，第五导向结构320位于第二本体301的第二表面，第二齿部330位于第二本体301的第三表面。其中第一表面为靠近第一齿条结构200的一面，第二表面为靠近驱动盒上盖600的一面，第三表面为靠近驱动结构100的齿轮110的一面。
第四导向结构310与第一齿条结构200的第三导向结构240配合，第四导向结构310包括第一导向轴311和第二导向轴312，第一导向轴311与第四导轨241位置配合，第一导向轴311可以在第四导轨241内滑动，第二导向轴312与第五导轨242位置配合，第二导向轴312可以在第五导轨242内滑动。
第五导向结构320与上盖600的第二滑槽601结构配合，第五导向结构320包括第三导向轴321和第四导向轴322，第三导向轴321和第四导向轴322可以在第二滑槽601内滑动。
第四导向结构310与第二滑槽601配合为第二齿条结构300的移动进行导向。
第二齿条结构300在第三表面上设置了全齿作为第二齿部330，第一齿条结构200只在第三面的局部上设置齿作为第一齿部230，第二齿部330的长度大于第一齿部230的长度。这样齿轮110可以同时与第一齿部230和第二齿部330啮合，也可以只与第二齿部330啮合。
作为优选，齿轮110上设置有定位筋111，定位筋111位于一个齿槽内，与第二齿条结构300上的定位槽331配合，安装时，定位筋111安装在第二齿条结构300的定位槽331内即可。其中，定位筋111的宽度为常规齿齿宽的1/10-1/5，相邻齿的齿宽小于常规齿的齿宽，且相邻齿与定位筋111在齿的宽度方向上存在间隔。这样能够避免定位筋111影响齿轮110对第二齿条结构300的驱动动作。
定位槽331包括两个定位齿，定位齿位于一个齿槽内，定位槽331与齿轮110的定位筋111结构配合，定位槽331用于驱动结构100安装。定位齿的齿宽为第二齿部330的常规齿的齿宽的1/10-1/5。定位齿位于第二齿部330远离第一齿条结构200的一侧。
由于第二齿条结构300在第三表面上为全齿设计，第二齿条结构300上可以设计1或2个定位槽331，在安装时，齿轮110与靠近连接结构3012的定位槽331配合，在空调器运行时，当齿轮110旋转一周后，定位筋111可以与远离连接结构3012的另一个定位槽331配合，以使驱动结构100能够正常驱动第二齿条结构300。
此外，第一齿条结构200的第一本体201为直板式结构，第二齿条结构300的第二本体301为折弯结构，当导风板400未开启时，第二齿条结构300的转轴302与第一齿条结构200与导风板400连接处的旋转轴430在导风板400的宽度方向上存在距离为L0的间隔，L0＞0mm。这样能够在驱动结构100同时驱动第一齿条结构200和第二齿条结构300时，使第一齿条结构200和第二齿条结构300同步运动，以推出或拉回导风板400；驱动结构100分别驱动第一齿条结构200和第二齿条结构300时，第一齿条结构200与第二齿条结构300之间产生距离差，转轴302或旋转轴430开始推动导风板400进行转动，使导风板400向上或向下进行转动。
下面根据图13至图17对导风板驱动组件的工作原理进行具体说明。
第一齿条与第一齿条结构200并排设置，在导风板400处于初始状态下，转轴302与旋转轴430在导风板400的宽度方向上存在间隔；
导风板400开启后，第一齿条结构200和第二齿条结构300沿直线方向同步运动将导风板400向前推出第一设定距离，然后第一齿条结构200和第二齿条开始差速运动。
本公开实施例的导风板400组件主要用于三种模式。
在第一模式下，第一齿条结构200继续向前伸出第二设定距离，第二齿条结构300继续向前伸出第三设定距离，第二设定距离的长度大于第三设定距离的长度，导风板400逆时针旋转，处于向下开口状态，可用于制热。
第二模式下，第一齿条结构200继续向前伸出第二设定距离后静止，第二齿条结构300继续向前伸出大于第二设定距离的长度，使导风板400处于向上开口状态，可用于制冷。
第三模式下，第一齿条结构200继续向前伸出第二设定距离，第二齿条结构300继续向前伸出第四设定距离，第二设定距离的长度等于第四设定距离的长度，导风板400当前所在平面与导风板400在初始状态所在平面平行，可以用于上下送风。
相应的，导风板400组件主要包括以下五种状态。
第一状态为初始状态，第一齿条结构200的第一齿部230和第二齿条结构300的第二齿部330均与齿轮110啮合，同时，第一齿条结构200的第一轴体221及第二齿条结构300的第三轴体上端双定位柱分别与下盖500及上盖600导轨槽上端接触限位，导风板400关 闭，机构锁止；
第二齿条结构300的转轴302与第一齿条结构200与导风板400连接处的旋转轴430在导风板400的宽度方向上存在距离为L0的间隔，L0＞0mm。其中，L0的大小可以根据用户需求进行定制。
第二状态为导风板400推出状态：导风板400伸出距离L1。
其中，L1≥0mm。
电机驱动齿轮110带动第一齿条结构200和第二齿条结构300向前伸出，第一推动轴121和第二推动轴131按行程分别进入第一齿条结构200的第一导轨211和第二导轨212，此时第一导轨211和第二导轨212不起推动作用；距离L1的数值根据开口及外观需要可以定制，此时空调可以进行上下送风，同时从上侧和下侧进行送风。
第三状态为导风板400向下开口状态：导风板400伸出至设定位置L2，其中，L2>L1。
在此过程中，第一齿条结构200的第一导轨211和第二导轨212开始起推动作用，第一齿条结构200的第一齿部230与齿轮110脱离，第一齿条结构200从第二状态向前伸出距离L3，第二齿条结构300从第二状态向前伸出距离L4，导风板400逆时针旋转角度θ1，导风板400向下开口，可用于制热，其中：L3＝L4+L0*tanθ1。
第四状态为导风板400回正状态：驱动结构100的各推动轴推动第一齿条结构200的第二轴体222在受到第一滑槽501的限位后，第一齿条结构200静止，第二齿条结构300继续伸出距离L0*tanθ1；此时第一齿条结构200和第二齿条结构300的伸出距离相同，通过第二齿条结构300的伸出与收回运动，可实现向下开口及摆风开口功能。
第五状态为导风板400向上开口状态，导风板400伸出距离L5，其中，L5＝L0*tanθ2。驱动结构100的各推动轴推动第一齿条结构200的第二轴体222在受到第一滑槽501的限位后，第一齿条结构200静止，第二齿条结构300继续伸出距离L0*tanθ2；此时导风板400向上开口，通过第二齿条结构300的伸出与收回运动，可实现向上开口及摆风开口功能。
在第三状态至第五状态中，第一齿条结构200和第二齿条结构300开始差速运动：第一齿条结构200的第二轴体222在受到第一滑槽501的限位后，会停止向前运动，第二齿条结构300在齿轮110的带动下继续延伸，推动导风板400旋转，实现向下开口(制热)--上下开口(回正)--向上开口(制冷)角度，并在此范围内可实现往复循环。
其中，通过设定第二齿条结构300的伸出距离L4和L5，可实现不同的开口角度，θ1和θ2的取值范围为[0,90°)。
具体的，在第一状态时，第一齿条结构200与齿轮110相啮合，第一推动轴121、第二推动轴131和第三推动轴141均处于脱轨状态，此时第一齿条结构200与齿轮110啮合， 第一齿条结构200可与第二齿条结构300同步移动。
在第二状态时，第一推动轴121按行程进入第一导轨211，第二推动轴131按行程进入第二导轨212，第三推动轴141处于脱轨状态，第一导轨211和第二导轨212不起带动作用，第三推动轴141处于脱轨状态。
在第三状态时，第一齿条结构200与齿轮110相脱离，第一推动轴121开始推动第一导轨211，第二推动轴131开始推动第二导轨212，第三推动轴141处于脱轨状态，在第一导轨211和第二导轨212的作用下第一齿条结构200向前伸出，直到第一本体201受到第一滑槽501的限位，处于静止状态，导风板400处于向下开口状态，可以用于制热。
在第四状态时，第一齿条结构200与齿轮110相脱离，第一推动轴121和第二推动轴131处于脱轨状态，第三推动轴141从开口端开始进入第三导轨213，且第一本体201受到第一滑槽501的限位，处于静止状态。
在第五状态时，第一齿条结构200与齿轮110相脱离，第一推动轴121和第二推动轴131处于脱轨状态，第三推动轴141位于第三导轨213内，且第一本体201受到第一滑槽501的限位，处于静止状态，导风板400处于向上开口状态，可以用于制冷。当第三推动轴141达到第三导轨213的闭口端时，驱动结构100到达运动极限位置。
关机时，齿轮110反向运转实现从第五状态至第一状态的循环。
本申请采用第一齿条结构200作为推出导风板400本体的主要结构，第二齿条结构300作为推动导风板400旋转的主要结构，第一齿条结构200和第二齿条结构300配合实现导风板400的大角度旋转，其中，第二齿条结构300的向上折弯设计能够用于推动导风板400旋转。
本申请的驱动结构100可以在同步运动阶段同步驱动第一齿条结构200和第二齿条结构300，使导风板400推出，在差速运动阶段分别推动第一齿条结构200和第二齿条结构300，这样可以使导风板400绕旋转轴430转动，本申请的导风板400驱动组件采用一组驱动结构100即可实现导风板400的推出和旋转动作，解决驱动结构100数量多导致空调器成本升高、导风板400运动可靠性低的问题。
