本申请要求2017年04月28日申请的，申请号为201710291740.9，名称为“一种空调及其导风板运动机构”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及空调生产技术领域，特别涉及一种空调及其导风板运动机构。
背景技术
空调导风板的作用在于对空调吹出的气流进行导流，以便使暖风或者冷风均匀的吹向室内，传统空调导风板运动机构主要是导风板按照某个转动中心做圆周运动实现上下扫风与导风作用。
一种情况是导风板的转动中心位于空调出风口内，这种情况下导风板一直处于出风口内，导风板本身会对空调的出风形成一定的阻碍，并且为了留出转动间隙，导风板闭合后与空调面板之间存在较大的缝隙，容易导致灰尘进入空调室内机中；
另一种情况是导风板的转动中心位于出风口的下沿，也就是导风板的下端铰接在出风口的下沿，这种导风板打开至水平位置且处于制冷模式下时，由于冷风会直接吹送至导风板的后沿，使得导风板上凝露严重，甚至出现滴水的不良情况。
因此，如何能够使得空调导风板的运动更为合理，以提高客户对空调的使用感受是目前本领域技术人员亟需解决的技术问题。

优选的，所述摆杆本体呈椭圆状。

优选的，所述导风板摆杆上还设置有用于避让所述行星齿轮的转轴的弧形避让槽。
本申请中所公开的空调，该空调设置有上述任意一项所公开的导风板运动机构。
本领域技术人员容易理解的是，由于转动摆杆通过第一铰接点铰接在基板上，并且其具有动力输入，这使得转动摆杆可以绕第一铰接点自转，导风板摆杆的中部通过第二铰接点铰接在转动摆杆上，并且导风板摆杆的上端还具有动力输入，因此导风板摆杆在跟随转动摆杆沿第一铰接点公转的同时还在沿第二铰接点自转，这使得导风板摆杆带动导风板运动的同时 还可以实现了导风板的角度变化，产生上下摆动的效果；而通过第三铰接点铰接在转动摆杆上的导风板连杆在转动摆杆的带动下能够推出或拉回导风板，以与导风板摆杆配合实现导风板的打开或关闭。因此，在导风板摆杆和导风板连杆的配合下，导风板能够实现开启和关闭的动作，并且在所述导风板打开时，所述导风板摆杆和所述导风板连杆可将导风板推出至出风口外部。
由于该种导风板运动机构在开启时能够使导风板的两个铰接点均产生运动，且在导风板打开时，导风板摆杆和导风板连杆能够配合将导风板推出至出风口外部，因此无论是导风板处于水平制冷位置，还是导风板处于全部打开的位置，出风口的气流均不会吹送至导风板的背面，在空调制冷时能够有效避免凝露的产生，提升用户的使用感受；同时，由于导风板的转轴没有设置在出风口内，因此无需预留导风板的转动间隙，且不存在阻风问题，空调关机后，在导风板摆杆和导风板连杆的配合下，导风板能够将出风口完全封闭，这可以有效避免灰尘进入空调室内机中。

具体实施方式
本申请的核心之一是提供一种空调的导风板运动机构，以能够使得空调导风板的运动更为合理，从而提高客户对空调的使用感受。
本申请的另一核心还在于提供一种具有上述导风板运动机构的空调。
为了使本技术领域的人员更好地理解本申请方案，下面结合附图和具体实施方式对本申请作进一步的详细说明。
本申请所公开的空调的导风板运动机构，包括转动摆杆3、导风板摆杆5、导风板连杆7以及导风板，转动摆杆3通过第一铰接点11铰接于基板10的内部，并且转动摆杆3自身具有动力输入，以便使转动摆杆3绕第一铰接点11自转，导风板摆杆5的中部通过第二铰接点12铰接在转动摆杆3上，并且导风板摆杆5一端靠近空调的出风口处，导风板摆杆5具有动力输入，优选的，导风板摆杆5远离出风口的一端具有动力输入，以使导风板摆杆5在跟随转动摆杆3绕第一铰接点11公转的同时绕第二铰接点12自转，导风板连杆7的一端也靠近出风口处，导风板连杆7远离出风口的一端通过第三铰接点13铰接在转动摆杆3上，导风板连杆7跟随转动摆杆3绕第一铰接点11转动，导风板的前后两端分别铰接在导风板摆杆5靠近出风口的一端，和导风板连杆7靠近出风口的一端。
需要进行说明的是，本申请实施例中的方向是按照图1中的视图来进行定义的，图1实际为空调室内机的侧视图，在该图的下部，关于方位上、下和前、后都已经标示清楚。本领域技术人员应当理解的是，上述方位的定义仅仅是为了方便对方案进行描述并帮助理解，不应当构成对本申请技术方案的限制。
可以理解的是，根据具体的应用场景以及连杆运动的结构原理，本说明书中提到的自转、转动和公转并非指整圈转动，而是实际需要进行一定范围的角度转动。
基板10作为整个导风板运动机构的安装基础，其通常情况下为空调壳体本身，当然，也可在空调壳体内另设专门用于安装导风板运动机构的基板10。
由于转动摆杆3通过第一铰接点11铰接在基板10上，并且其具有动力输入，这使得转动摆杆3可以绕第一铰接点11自转，导风板摆杆5的中部通过第二铰接点12铰接在转动摆杆3上，并且导风板摆杆5的上端还具有动力输入，因此导风板摆杆5在跟随转动摆杆3沿第一铰接点11公转的同时还在沿第二铰接点12自转，这使得导风板摆杆2带动导风板运动的同时还实现了导风板的角度变化，产生上下摆动的效果；而通过第三铰接点13铰接在转动摆杆3上的导风板连杆7在转动摆杆3的带动下能够推出或拉回导风板，以与导风板摆杆5配合实现导风板的打开或关闭。因此，在导风板摆杆5和导风板连杆7的配合下，导风板能够实现开启和关闭的动作，并且在导风板打开时，导风板摆杆和导风板连杆可将导风板推出至出风口外部。
由于该种导风板运动机构在开启时能够使导风板的两个铰接点均产生运动，且在导风板打开时，导风板摆杆5和导风板连杆7能够配合将导风板推出至出风口外部，因此无论是导风板处于水平制冷位置，还是导风板处于全部打开的位置，出风口的气流均不会吹送至导风板的背面，在空调制冷时能够有效避免凝露的产生，提升用户的使用感受；同时，由于导风板的转轴没有设置在出风口内，因此无需预留导风板的转动间隙，且不存在阻风问题，空调 关机后，在导风板摆杆5和导风板连杆7的配合下，导风板能够将出风口完全封闭，这可以有效避免灰尘进入空调室内机中。
对转动摆杆3进行动力输入的方式并不限于一种，例如可以直接通过驱动电机驱动转动摆杆3转动，或者通过传动系统与转动摆杆3的配合实现对转动摆杆3进行动力输入，本实施例中提供了一种通过行星齿轮9与第一弧形齿条4配合带动转动摆杆3运动的方式，具体的，第一弧形齿条4设置在基板10上，具有动力的行星齿轮9至少包括沿第一弧形齿条4转动的第一齿轮91，行星齿轮9的转轴铰接于转动摆杆3上，以带动转动摆杆3绕第一铰接点11自转，如图4至图6中所示。
同理，对导风板摆杆5上端(远离出风口的一端)进行动力输入的形式也并不局限于一种，可以直接通过驱动电机对导风板摆杆5的上端进行动力输入，或通过传动机构对导风板摆杆5的上端进行动力输入，在本实施例中，行星齿轮9还包括与第一齿轮91固连的第二齿轮92，导风板摆杆5的上端是通过行星齿轮9中的第二齿轮92进行驱动的，导风板摆杆5的上端设置有第二弧形齿条51，第二齿轮92与第二弧形齿条52啮合以带动导风板摆杆5绕第二铰接点自转，如图7所示。
考虑到第二弧形齿条设计上的便利性，本实施例中第一齿轮91和第二齿轮92同心设置，如此可将第二弧形齿条51设计为标准的圆弧形即可。
在本案基础上，本领域技术人员可以根据导风板需要达到的运动轨迹对导风板摆杆5、导风板连杆7的长度，以及两者与转动摆杆3的铰接位置进行适应性调整。
如图8中所示，实线代表本申请实施例中导风板的运动轨迹，虚线代表现有技术中导风板的运动轨迹，可以看出，无论是导风板处于水平位置还是打开至最大位置，导风板的两端均已经位于出风口之外，制冷时冷风不会吹送至导风板的后沿，因此导风板板上的凝露可以大大减少；而且采用本实施例中的导风板运动机构，导风板在关闭后与出风口处的缝隙更小，可以更为有效的防止灰尘进入空调内部。
由于该种导风板运动机构在开启时能够使导风板的两个铰接点均产生运动，且在导风板打开时，导风板摆杆5和导风板连杆7均伸出所述出风口，因此无论是导风板处于水平制冷位置，还是导风板处于全部打开的位置，出风口的气流均不会吹送至导风板的背面，因此在空调制冷时能够有效避免凝露的产生，提升用户的使用感受。
不难理解的是，可以在行星齿轮9上直接设置一与行星齿轮9一起运动的驱动电机，该驱动电机在驱动行星齿轮9运动时，随行星齿轮9一起运动，也可以设置与行星齿轮9相配合的太阳轮2，通过太阳轮2对行星齿轮9进行动力输入，在本实施例中，还包括设置在基板10内，并且具有动力输入的太阳轮2，该太阳轮2与行星齿轮9啮合，并且太阳轮2也通过第一铰接点11铰接于基板10上。
需要进行说明的是，太阳轮2可以直接与电机相连，通过电机对太阳轮2直接输入动力， 也可以通过其他齿轮与其啮合输入动力，例如在本实施例中，还包括设置在基板10内，且与太阳轮2啮合的主动齿轮1，主动齿轮1与电机相连，以便向太阳轮2输入动力。
至此可以看出，该导风板运动机构实际可以仅通过一个电机带动主动齿轮1转动，就可实现整个导风板运动机构的联动，通过电机的正转和反转，可以实现导风板的打开和关闭动作，该导风板运动机构具有所需电机少，运作方式简单，无效动作时间短的优点。
更进一步的，第二铰接点12与第一铰接点11之间的距离小于第三铰接点13与第一铰接点11之间的距离，该种情况下，导风板连杆7和导风板摆杆5的长度设计较为容易；当然，第二铰接点12与第一铰接点11之间的距离也可小于，或者等于第三铰接点13与第一铰接点11之间的距离，此时需要对导风板连杆7和导风板摆杆5的长度进行设计，以满足导风板的开关动作需求。整体来看，该机构实质上为一个五杆运动机构，不考虑沿整个机构沿第一铰接点11的公转，那该机构实质上为一个四杆联动机构。
图1至图3中，导风板分别处于关闭状态、水平状态、打开至最大位置状态，转动摆杆3的形状实际不受限制，在本实施例中，转动摆杆3包括摆杆本体，以及与摆杆本体远离第一铰接点11的一端相连，并远离摆杆本体向外延伸的凸耳，进一步的，第三铰接点13设置在该凸耳上，第二铰接点12位于摆杆本体与导风板摆杆5叠合的位置上，第二铰接点12的位置是根据导风板需要达到的摆动角度，定在摆杆本体与导风板摆杆5重合的合适位置。
开机时，电机驱动主动齿轮1顺时针转动，主动齿轮1带动太阳轮2逆时针转动，转动摆杆3将绕着第一铰接点逆时针自转，导风板连杆7跟随转动摆杆3绕第一铰接点转动的同时绕自身与转动摆杆3的铰接点转动，太阳轮2带动行星齿轮9做顺时针自转，同时行星齿轮9沿第一弧形齿条4做逆时针公转，行星齿轮9顺时针自转带动与其啮合的导风板摆杆5按自身转动中心顺时针自转，行星齿轮9的逆时针公转带动导风板摆杆5与行星齿轮9一起沿着第一弧形齿条4以第一铰接点为中心逆时针公转，因此导风板摆杆5与导风板之间的连接点，随着导风板摆杆5自身顺时针自转的同时随转动摆杆3的逆时针公转做非圆形弧线运动，当导风板到达极限位置时，导风板连杆7与导风板的连接点处于最下端位置，从而协助完成导风板的打开；在关机时，电机反转，导风板摆杆5与导风板的连接点，以及导风板连杆7与导风板的连接点均进行与开机时相反的运动，当导风板到达极限位置时，导风板连杆7与导风板的连接点处于最上端位置，从而协助完成导风板的关闭；当然，可以根据运行轨迹设定导风板运动轨迹为关闭和开打到极限位置上的任意两点位置之间的反复运动，当电机交替正转和反转时，就可以实现扫风运动。
如图1至图7中所示，导风板摆杆5靠近行星齿轮9的一端设置有容纳行星齿轮9的容纳腔，第二弧形齿条51设置在容纳腔的侧壁上，考虑到空调室内机内部空间的局限性，行星齿轮9与导风板摆杆5较为靠近。
进一步的，行星齿轮的转轴铰接在转动摆杆3上，为了避免两者运动时产生干涉，导风 板摆杆5上还设置有用于避让行星齿轮9的转轴的弧形避让槽8。
除此之外，本申请还公开了一种空调，该空调包括上述任意一实施例中所公开的导风板运动机构。
由于采用了上述导风板运动机构，因此该空调兼具上述导风板运动机构相应的技术优点，本文中对此不再进行赘述。
以上对本申请所提供的空调及其导风板运动机构进行了详细介绍。本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以对本申请进行若干改进和修饰，这些改进和修饰也落入本申请权利要求的保护范围内。
