具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1和图2所示，本发明实施例提供的面板驱动机构，包括第一支架 12和第二支架19，其中，第一支架12的运动轨迹和第二支架19的运动轨迹位于同一平面内，即第一支架12和第二支架19在同一平面内运动。
本发明提供的面板驱动机构中，第一支架12的运动轨迹和第二支架19的运动轨迹位于同一平面内，则实现了第一支架12和第二支架19设置在同一平面上，从而减小了驱动盒的厚度，减小了驱动盒占用的空间。
上述面板驱动机构中，第一支架12和第二支架19均为齿条，上述面板驱动机构还包括驱动第一支架12和第二支架19同向运动的齿轮机构。
可以理解的是，齿轮机构驱动第一支架12和第二支架19同向运动，是指第一支架12和第二支架19沿同一方向移动，以保证与第一支架12和第二支架19相连的面板实现关闭和打开。具体地，第一支架12被推出向外运动，则第二支架19也被推出向外运动；第一支架12向内运动，则第二支架19也向内运动。此处，内和外，分别指驱动盒体15的内部和外部。
上述面板驱动机构中，第一支架12和第二支架19还可为其他结构，并不局限于齿条，例如连杆等。若第一支架12和第二支架19为其他结构，对于驱动第一支架12和第二支架19同向运动的机构可根据实际需要进行选择，本发明实施例对此不做限定。
根据齿轮机构的特点，可优先选择上述第一支架12和第二支架19通过齿轮机构限位连接。这样，齿轮机构在传递运动的同时，还实现对第一支架12和第二支架19的限位，便于保证第一支架12和第二支架19在同一平面内运动，较现有技术中单独设置限位部件相比，有效减少了限位部件，简化了结构，提高了装配效率；而且，利用齿轮机构进行限位，提高了限位可靠性。
当然，也可选择第一支架12和第二支架19不采用齿轮机构进行限位，而是采用其他的限位结构或者限位部件进行限位，并不局限于上述实施例。
上述面板驱动机构中，第一支架12和第二支架19通过齿轮机构限位连接，该齿轮机构存在多种结构。按齿轮机构的主动齿轮数目进行分类，主要有两类，一类主动齿轮16为一个，另一类主动齿轮16为两个。
为了简化结构，优先选择主动齿轮16为一个，具体地，上述齿轮机构包括一个主动齿轮16和一个从动齿轮组件，主动齿轮16通过从动齿轮组件驱动第一支架12和第二支架19同向运动。
可以理解的是，由于从动齿轮组件与第一支架12和第二支架19的配合关 系为啮合，则从动齿轮组件通过与第一支架12和第二支架19的啮合实现限位。
上述齿轮机构中，从动齿轮组件包括：与第一支架12啮合的第一从动齿轮14，与第二支架19啮合的第二从动齿轮17。可选择第一从动齿轮14和第二从动齿轮17中的一者与主动齿轮16啮合，此时，第一从动齿轮14和第二从动齿轮17啮合或者通过连接齿轮相连；还可选择主动齿轮16通过传递齿轮与第一从动齿轮14和第二从动齿轮17相连，例如，主动齿轮16与连接齿轮啮合，第一从动齿轮14和第二从动齿轮17中，一者与连接齿轮啮合，另一者与连接齿轮通过传递齿轮相连，也可选择第一从动齿轮14和第二从动齿轮17均通过传递齿轮与连接齿轮相连。
上述齿轮机构中，对于连接齿轮和传递齿轮的数目和大小，根据实际需要进行设计，本发明实施例对此不做限定。
为了保证第一支架12和第二支架19以相同速度运动，上述第一从动齿轮14和第二从动齿轮17的模数相同，第一从动齿轮14和第二从动齿轮17的齿数相同。
对于第一从动齿轮14和第二从动齿轮17的模数、齿数的具体数值，可根据实际需要进行设计，本发明实施例对此不做限定。对于第一从动齿轮14和第二从动齿轮17的位置可以根据第一支架12和第二支架19的位置或尺寸进行调整。
上述面板驱动机构中，若主动齿轮16为两个，则上述齿轮机构包括：第一主动齿轮，第二主动齿轮，相连的第一从动齿轮组件和第二从动齿轮组件，其中，第一主动齿轮通过第一从动齿轮组件驱动第一支架12运动，第二主动齿轮通过第二从动齿轮组件驱动第二支架19运动。
可以理解的是，第一从动齿轮组件和第二从动齿轮组件所包括的从动齿轮可为一个，也可为两个以上。本发明实施例对第一从动齿轮组件和第二从动齿轮组件的具体结构不做限定，只要能够驱动第一支架12和第二支架19同向运动运动即可。第一主动齿轮通过第一从动齿轮组件驱动第一支架12运动，则表明第一从动齿轮组件的一个从动齿轮与第一支架12啮合；同理，第二从动齿轮组件的一个从动齿轮与第二支架19啮合。第一从动齿轮组件和第二从动齿轮组件相连，是指第一从动齿轮组件的一个从动齿轮与第二从动齿轮组件的一个从动齿轮啮合，以保证第一支架12和第二支架19的限位连接。
上述面板驱动机构中，还可根据实际需要选择其他结构的齿轮机构，只有能够驱动第一支架12和第二支架19同向运动运动。
进一步地，齿轮机构位于第一支架12和第二支架19之间。这样，进一步提高了限位性能，使得第一支架12与第一支架19之间的距离在合理范围内，保证了运动轨迹。
第一支架12和第二支架19可以相同速度运动，也可以不同速度运动。若二者以相同速度运动，则第一支架12和第二支架19均与面板固定连接；若二者以不同速度运动，则第一支架12和第二支架19中至少一者与面板可滑动连接，以保证面板的开启和关闭。
为了简化结构，方便设置，优先选择齿轮机构驱动第一支架12和第二支架19同速运动。
对于第一支架12和第二支架19的形状，亦需要根据实际需要进行设计。优选地，上述第一支架12和第二支架19均呈弧形。可以理解的是，第一支架12和第二支架19均向同一方向凸出。
对于第一支架12和第二支架19的弧度、长度，根据实际需要进行设计，本发明实施例对此不做限定。
当然，也可选择第一支架12和第二支架19为其他形状，例如直线型。
上述面板驱动机构中，如图2所示，空调器处于关闭状态，开机时，电机驱动主动齿轮16，带动第一从动齿轮14和第二从动齿轮17转动。第一从动齿轮14带动第一支架12向外推出，第二从动齿轮17带动第二支架19也向外运动，面板11和第一支架12、第二支架19之间采用卡勾配合，面板11也就随之打开。如图1所示，面板11打开到极限位置，关闭空调时，电机驱动主动齿轮16，主动齿轮16带动第一从动齿轮14和第二从动齿轮17，第一从动齿轮14带动第一支架12向内收回，第二从动齿轮17带动第二支架19向内收回，使面板11闭合。
通常出风口或者进风口均设在竖直板上，为了方便关闭面板，优先选择第一支架12所对应的圆心和第二支架19所对应的圆心连线为竖直直线。
可以理解的是，第一支架12所对应的圆心和第二支架19所对应的圆心连线为竖直直线，是指采用上述面板驱动机构的空调安装后，即图1和图2所示的状态，两个圆心的连线为竖直直线。
当然，若出风口或者进风口不在竖直板上，则需要调整第一支架12所对应的圆心和第二支架19所对应的圆心的相对位置关系。
基于上述实施例提供的面板驱动机构，本发明实施例还提供了一种空调器，该空调器包括：面板11，与面板11相连的面板驱动机构；其中，面板驱动机构为上述实施例所述的面板驱动机构。
由于上述实施例提供的面板驱动机构具有上述技术效果，本发明实施例提供的空调器具有上述实施例提供的面板驱动机构，则本发明实施例提供的空调器也具有相应的技术效果，本文不再赘述。
优选地，上述面板11为进风面板。当然，也可选择上述面板11为出风面板，根据实际需要进行选择。
上述空调器中，面板驱动机构通常设置于驱动盒体15内，形成驱动盒。具体地，主动齿轮16、从动齿轮组件均位于驱动盒体15内，驱动盒体15具有供第二支架19和第一支架12伸出的通孔。
为了便于第二支架19和第一支架12沿设定轨迹运动，上述驱动盒体15内设有：供第一支架12运动的上导向结构，供第二支架19运动的下导向结构。通常下导向结构和上导向结构均为导向槽151，第一支架12和第二支架19均具有与导向槽151配合的导向柱。
为了进一步限位，上述面板驱动机构还包括：沿第一支架12的宽度方向限位第一支架12的第一限位垫片13；沿第二支架19的宽度方向限位第二支架19的第二限位垫片18；其中，第一限位垫片13与第二限位垫片18均固定于驱动盒体15内。
优选地，第一限位垫片13和第二限位垫片18均为三个，两个第一限位垫片13相对设于第一支架12的两侧，另一个第一限位垫片13和第一从动齿轮14相对设于第一支架12的两侧；两个第二限位垫片18相对设于第二支架19的两侧，另一个第二限位垫片18和第二从动齿轮17相对设于第二支架19的两侧。
传统壁挂空调机的出风口是露在空调内机壳体外边的，容易进灰尘及影响外观。为了使壁挂式空调实现全封闭外观，且不能阻碍空调的进出风结构，家用壁挂式空调需要设计一种运动机构在空调运行时把面板支撑起来将出风口 打开，并加大进风面积。同时在空调停止运行时将面板闭合，使整改空调内机形成一种全封闭状态。现有的一些面板运动机构的常用结构为行星齿轮带动，结构较为复杂。所以如何去掉行星齿轮，使面板运动机构的结构优化简洁及运行可靠是一个很大的难题。
本发明提供了一种面板驱动机构，用于安装在空调室内机上，控制面板开合，在空调运行时向外打开面板，为空调进风口和出风口创造出较大的进出风面积；在空调关闭时向内回收面板，使面板将进风口和出风口封闭，避免外界的灰尘进入空调室内机中。但本发明的面板驱动机构并不局限于壁挂式空调，也可应用于柜式空调，甚至可以应用于加湿器、空气净化器等电器中。
参见图3和图4所示，本发明的面板驱动机构包括上支架2110、下支架2120、支撑组件和驱动组件，上支架2110和下支架2120为弯曲方向相同的弧形支架，上支架2110和下支架2120的一端用于与面板2200相铰接。上支架2110和下支架2120设置在支撑组件中，驱动组件用于驱动上支架2110和下支架2120分别以其所在弧线作为运动轨迹同向运动，从而可以带动面板2200以弧线形轨迹打开进风口和出风口，运行轨迹以最小的位移为空调进风口和出风口创造出较大的进出风面积。
在本实施方式中，上支架2110和下支架2120上分别设置有上齿型部2111和下齿型部2121，驱动组件包括第一齿轮2130和第二齿轮2140，第一齿轮2130与上齿型部2111相啮合，用于带动上支架2110以其所在弧线作为运动轨迹运动；第二齿轮2140与下齿型部2121相啮合，用于带动下支架2120以其所在弧线作为运动轨迹运动。以齿轮驱动齿条，从而带动上支架2110和下支架2120运动的方式，使驱动组件的结构最简单，且最稳定。
其中上支架2110和下支架2120上设置的上齿型部2111和下齿型部2121既可以是在上支架2110和下支架2120上直接加工出齿，也可以是将加工有齿的零件固定在上支架2110和下支架2120上，例如将弧形齿条固定在上支架2110和下支架2120上。
进一步的，上齿型部2111与下齿型部2121相对设置，即上齿型部2111 设置在上支架2110的弧形外侧，下齿型部2121设置在下支架2120的弧形内侧，第一齿轮2130与第二齿轮2140位于上支架2110与下支架2120之间，且相啮合；驱动组件还包括驱动电机，驱动电机用于驱动第一齿轮2130或第二齿轮2140。第一齿轮2130与第二齿轮2140相啮合，可以使上支架2110和下支架2120保持同步运动，且只需要一个驱动电机就可以同时带动上支架2110和下支架2120运动。
更进一步的，驱动组件还包括驱动齿轮2150，驱动齿轮2150设置在驱动电机的输出轴上，且与第一齿轮2130或第二齿轮2140相啮合。驱动电机通过驱动齿轮2150带动第一齿轮2130或第二齿轮2140，有利于调整电机与齿轮之间的传动减速比，降低电机成本。
当需要打开面板2200时，驱动电机带动驱动齿轮2150逆时针转动，驱动齿轮2150带动第二齿轮2140顺时针转动，第二齿轮2140带动第一齿轮2130逆时针转动，上齿型部2111和下齿型部2121在第一齿轮2130和第二齿轮2140驱动下向上支架2110和下支架2120的外端方向运动，从而带动面板2200按照弧线轨迹运动打开进风口和出风口。
当需要闭合面板2200时，驱动电机带动驱动齿轮2150顺时针转动，驱动齿轮2150带动第二齿轮2140逆时针转动，第二齿轮2140带动第一齿轮2130顺时针转动，上齿型部2111和下齿型部2121在第一齿轮2130和第二齿轮2140驱动下向上支架2110和下支架2120的内端方向运动，从而带动面板2200按照弧线轨迹运动返回初始位置，封闭进风口和出风口。
除了上述实施方式之外，还存在另一个实施方式：上齿型部与下齿型部相对设置，第一齿轮与第二齿轮位于上支架与下支架之间，且相啮合；驱动组件还包括驱动电机，驱动电机用于直接驱动第一齿轮或第二齿轮转动。采用驱动电机直接驱动第一齿轮或第二齿轮，省略驱动齿轮，使面板驱动机构的体积更小，适应产品小型化的需求。
在上述两种实施方式中，上齿型部2111与下齿型部2121的模数相同，第 一齿轮2130与第二齿轮2140的模数相同。齿轮和齿条的模数相同，可以使上支架2110和下支架2120运动的同步性更好，面板的运动更加平稳。
当然还存在第三种实施方式：上齿型部2111与下齿型部2121同向设置，即上齿型部2111和下齿型部2121设置在上支架2110和下支架2120的弧形内侧或外侧的相同侧，第一齿轮2130与第二齿轮2140之间通过齿轮组传动连接；驱动组件还包括驱动电机，驱动电机用于驱动第一齿轮2130、第二齿轮2140或齿轮组中的任一齿轮。即使上齿型部2111和下齿型部2121同向设置，也可以采用齿轮组将第一齿轮2130和第二齿轮2140关联起来，使第一齿轮2130和第二齿轮2140同步运转，保证上支架2110和下支架2120运动的同步性。
除了上述以齿轮齿条作为驱动组件的实施方式以外，驱动组件还可以采用其他方式，驱动组件包括第一推杆和第二推杆，第一推杆和第二推杆分别与上支架2110和下支架2120的相铰接，第一推杆和第二推杆能够在动力装置的推拉作用下带动上支架2110和下支架2120分别以其所在弧线作为运动轨迹同向运动。例如采用油缸作为动力装置，将油缸的活塞杆与第一推杆相铰接，通过活塞杆的往复运动使第一推杆对上支架2110产生推拉作用力，使上支架2110可以以其所在弧线作为运动轨迹运动，同理，第二推杆也可以采用相同的方式对下支架2120产生推拉作用力，使下支架2120可以以其所在弧线作为运动轨迹运动。这种驱动组件省略了齿轮、齿条，同样可以实现本发明的目的，使结构更简单，运行更稳定。
具体的，支撑组件包括驱动盒2160和若干定位轴承2170，若干定位轴承2170转动连接在驱动盒2160上，且定位轴承2170的外缘分别与上支架2110和下支架2120的上下两侧边相接触。定位轴承2170可以使上支架2110和下支架2120的运行更加平稳，不易产生晃动，且可以保证上支架2110和下支架2120的运行轨迹不会脱离其所在弧线。
进一步的，支撑组件还包括限位装置，限位装置设置在上支架2110和\或下支架2120与驱动盒2160之间，用于限制上支架2110和下支架2120相对驱 动盒2160的运动范围。如果上支架2110和下支架2120为同步运动方式，则限位装置只需要安装在上支架2110或下支架2120其一上即可；如果上支架2110和下支架2120为独立的运动方式，可以在上支架2110和下支架2120上都设置限位装置，分别对上支架2110和下支架2120进行限位。
在图3和图4所示的实施方式中，限位装置包括限位柱2180和限位槽2190，限位槽2190开设在驱动盒2160上，限位柱2180的一端固定连接在上支架2110和\或下支架2120上，另一端设置在限位槽2190内，限位槽2190用于限制限位柱2180的运动范围。这种限位方式简单，且稳定，并且对上支架2110、下支架2120的运动轨迹也有一定保障。
参见图5所示，作为一种优选的实施方式，上支架2110和下支架2120所在弧线的半径r1和r2相同，则上支架2110和下支架2120的运行轨迹完全相同，可以带动面板始终保持平行的方式运动，节省运动空间，避免发生碰撞。
进一步的，上支架2110和下支架2120所在弧线的圆心O1和O2位于同一条竖直直线上，则可以使面板2200在运动过程中也始终保持竖直的状态，在水平方向上不会占用太多运动空间，避免面板发生磕碰。
本发明还提供一种空调室内机，包括以上任一实施方式的面板驱动机构，上支架2110和下支架2120的外端与面板2200相铰接，其中具体的铰接方式为：上支架2110和下支架2120的外端分别设置有转轴2112，面板2200对应上支架2110和下支架2120的位置处分别设置有用于连接转轴2112的卡钩2210；当然也可以采用插销螺钉固定转轴等铰接形式。
为了保证面板2200开合过程的稳定性，面板驱动机构为两组，分别设置在空调室内机机体的左右两侧。
目前室内壁挂机的前面板都是固定不动的，前面板通过卡扣与壁挂机的壳体相连，空调出风口开设在前面板下部，出风口位置设置导风板，当空调开启时，导风板打开，出风口向外吹风，空调关闭后，导风板闭合。
但是目前室内壁挂机的导风板在闭合时无法将出风口完全封闭，导风板与 空调的出风口处留有较大缝隙，这使得外界灰尘容易通过该缝隙进入到空调室内机的内部，对空调室内机造成污染。
因此，面板可开启式的室内壁挂机应运而生，该种壁挂机在空调开启时，前面板向前向上运动，从而使前面板与壁挂机壳体之间产生缝隙供空调出风，在空调关闭时，前面板向相反方向运动，与壁挂机壳体完全扣合，以避免壁挂机内部进入灰尘。
然而，目前壁挂机空调在开启时其前面板在驱动机构的带动下底部向前向上翻开，从而使底部的出风口露出，虽然能够实现前面板的整体开启，但是打开之后的前面板处于倾斜状态，这不仅影响室内机空调整体的美观性，而且还需占用较大的翻转空间。
因此，如何能够优化壁挂机空调的开启方式是目前本领域技术人员亟需解决的技术问题。
本发明的核心之一是提供一种前面板运动机构，以期能够优化壁挂机空调的开启方式，使空调整体更加美观并有效减小空调室内机所需的空间。
本发明的另一核心还在于提供一种采用上述前面板运动机构的空调室内机。
为了使本技术领域的人员更好地理解本发明方案，下面结合附图和具体实施方式对本发明作进一步的详细说明。
请参考图6至图9，图6为本发明实施例中所公开的前面板运动机构在闭合时的结构示意图，图7为本发明实施例中所公开的前面板运动机构在打开时的结构示意图，图8为本发明实施例中所公开的与上部弧形齿条配合的变形卡口的放大图，图9为本发明实施例中所公开的与下部弧形齿条配合的变形卡口的放大图。
本发明所公开的前面板运动机构中，包括前面板310和驱动组件，并且前面板310上设置有具有开口的变形卡口39，驱动组件用于与前面板310相连的一端设置有安装轴端38，安装轴端38由变形卡口39的开口处嵌入变形卡口39内部并与前面板310可转动连接。
上述实施例中的前面板运动机构，由于前面板310与驱动组件的前端通过变形卡口39与安装轴端38配合实现了可转动连接，因而当驱动组件带动前面板310向前上方运动时，在前面板310自身重力的作用下，其能够绕驱动组件 的前端转动，因而能够始终保持竖直状态，当打开完成后，前面板310保持竖直，并且其位于空调室内机壳体的前上方，前面板310与空调室内机壳体之间形成了出风口，这不仅使得空调开机口更具美观性，而且还有效减小了空调开机过程中所需占用的空间，优化了空调壁挂机前面板的开启方式。
采用变形卡口39与驱动组件前端的安装轴端38配合安装，有效提高了安装的便利性，无需任何紧固件，仅需将安装轴端38安入变形卡口39内即实现了弧形齿条前端与前面板310的可转动连接。
更进一步的，考虑到变形卡口39与驱动组件前端的安装轴端配合的可靠性，本实施例中的变形卡口39优选的为圆弧形勾状卡口，如图8中所示，并且该变形卡口39的开口处所对应的圆心角不大于60°，以保证变形卡口39对安装轴端38的包裹性，避免安装轴端38的脱出，该种形状的变形卡口39也可称为鹰嘴状变形卡口。
由于安装轴端38在运动时是向前上方运动，为了进一步避免安装轴端38的脱出，本实施例中的变形卡口39的开口朝向前面板310的前下方，如图8中所示。
在本发明实施例中，驱动组件具体包括主动齿轮32和弧形齿条，其中，主动齿轮32位于室内机壳体31内，并且该主动齿轮32在驱动机构的带动下可以实现正转和反转，弧形齿条滑动设置在室内机壳体31中，并且弧形齿条与主动齿轮32啮合，弧形齿条的凹面朝上，其前端设置有上述安装轴端，以实现与空调室内机的前面板310的可转动连接。
上述实施例中所公开的前面板运动机构由于弧形齿条滑动设置在室内机壳体中，并且弧形齿条的凹面朝上，其前端与空调室内机的前面板310可转动连接，当空调室内机打开时，在主动齿轮32的带动下，弧形齿条向外伸出，由于弧形齿条的形状，其前端将带动前面板310向前上方运动，而前面板310与弧形齿条的前端为可转动连接，因而在前面板310自身重力的作用下，前面板310能够始终保持竖直状态，当打开完成后，前面板310保持竖直，并且其位于室内机壳体31的前上方，前面板310与室内机壳体31之间形成了出风口；而在空调室内机关闭时，主动齿轮32向相反方向转动即可。
由此可见，上述实施例中所公开的技术方案利用弧形齿条的特殊形状，仅通过齿轮和齿条的配合即达到了使前面板向前上方运动的效果，同时弧形齿条 与前面板310的可转动连接，保证了前面板310始终处于竖直状态，相比于现有技术，该种前面板运动机构结构更加简单，装配更加便捷，同时占用的室内机空间也更小。
本领域技术人员不难理解的是，弧形齿条可以设置一个也可设置多个，当弧形齿条设置一个时，在空调室内机的长度方向上，该弧形齿条应当位于空调室内机的中部，以避免前面板310的两侧产生倾斜。
在上下方向上，为了保证前面板310运动的稳定性，本实施例中具体设置了两个弧形齿条，如图6和图7中所示，弧形齿条具体包括与前面板310的上端可转动连接的上部弧形齿条331和与前面板310的下端可转动连接的下部弧形齿条332，上部弧形齿条331的凸面设置有上部啮合齿，下部弧形齿条332的凹面设置有与上部啮合齿模数相同的下部啮合齿，主动齿轮32位于上部弧形齿条331和下部弧形齿条332之间，并且通过中间传动机构带动上部弧形齿条331和下部弧形齿条332运动。
在设计时尤其注意，上部弧形齿条331和下部弧形齿条332在运动时需要保证同步性，上部弧形齿条331向上托举前面板310多大距离，下部弧形齿条332也应当向上托举前面板310多大距离，上部弧形齿条331向前推出前面板310多大距离，下部弧形齿条332也应当向前推出前面板310多大距离。运动的同步性主要依靠对弧形齿条的弧度、齿条的齿数和模数进行设计来保证。
与此同时，还可对变形卡口39进行优化设计，如图6至9中所示，前面板310上用于与上部弧形齿条331的安装轴端38配合的变形卡口39为圆弧形勾状卡口，并且该变形卡口39的开口朝向前面板前下方；前面板310上用于与下部弧形齿条332的安装轴端38配合的变形卡口39由相对设置的上端卡爪和下端卡爪构成。
上部的变形卡口39可以有效防止安装轴端38的脱出，而下部的变形卡口39可以方便下部弧形齿条332的装配。更进一步的，上端卡爪和下端卡爪上还设置有方便下部弧形齿条332的安装轴端38嵌入变形卡口39内的导向斜面。
如图6和图7中所示，本发明实施例中的中间传动机构包括第一中间齿轮34和第二中间齿轮35，第一中间齿轮34和第二中间齿轮35的布置形式不受局限，例如在一种方式中，第一中间齿轮34和第二中间齿轮35啮合，并且第 一中间齿轮34与下部弧形齿条332啮合，第二中间齿轮35与上部弧形齿条331啮合，主动齿轮32与第一中间齿轮34或第二中间齿轮35中的任意一个啮合。这样设置可以保证主动齿轮32的动力通过第一中间齿轮34和第二中间齿轮35分别传递至下部弧形齿条332和上部弧形齿条331上。在另一种方式中，第一中间齿轮34与下部弧形齿条332啮合，第二中间齿轮35与上部弧形齿条331啮合，主动齿轮32设置在第一中间齿轮34和第二中间齿轮35之间，并分别与第一中间齿轮34和第二中间齿轮35啮合，主动齿轮32的动力通过第一中间齿轮34和第二中间齿轮35分别传递至下部弧形齿条332和上部弧形齿条331上。
可以理解的是，弧形齿条与室内机壳体31的连接方式也包括多种，例如在室内机壳体31上设置滑道，弧形齿条的侧面设置有可嵌入滑道内的滑块，滑块与滑道配合后实现弧形齿条与室内机壳体31的可滑动连接。
虽然上述方法可以实现弧形齿条在室内机壳体31中的滑动连接，但是其运行起来阻力和噪音较大，对于越来越追求静音效果的空调室内机而言会带来不利影响，为此本实施例中提供了另外一种弧形齿条与室内机壳体31的配合方式，请参考图6和图7，在上部弧形齿条331的外部罩设有上部导向壳体3311，在下部弧形齿条332外部罩设有下部导向壳体3322，上部导向壳体3311的凸面开设有沿自身长度方向延伸，并供第二中间齿轮35穿入的上部让位槽，该让位槽可以保证第二中间齿轮35与上部弧形齿条331啮合，并允许上部弧形齿条331进行前后运动，下部导向壳体3322的凹面开设有沿自身长度方向延伸，并且供第一中间齿轮34穿入的下部让位槽，下部让位槽可以保证第一中间齿轮34与下部弧形齿条332啮合，并允许下部弧形齿条332进行前后运动，在室内机壳体31内部还设置有第一导向轴承36和第二导向轴承37，其中第一导向轴承36与上部导向壳体3311的凸面和下部导向壳体3322的凹面配合；第二导向轴承37与上部导向壳体3311的凹面和下部导向壳体3322的凸面配合，第一导向轴承36和第二导向轴承37构成上部弧形齿条331和下部弧形齿条332运动的滑道。
在上部弧形齿条331和下部弧形齿条332前后运动时，第一导向轴承36和第二导向轴承37配合，将上部弧形齿条331和下部弧形齿条332与室内机壳体31之间的滑动转化为滚动运动，从而有效减小上部弧形齿条331和下部 弧形齿条332在运动过程中所受到的阻力并减小噪音，这不仅降低了空调室内机的能耗，还使得用户的舒适性得以提升。
第一导向轴承36和第二导向轴承37的结构相同，并且均包括芯轴和可转动地设置在芯轴上的转动套，当然，转动套与芯轴之间应当设置滚珠，以保证转动套在绕芯轴转动时具有较小的阻力。
为了进一步保证前面板310运动的稳定性，上部弧形齿条331和下部弧形齿条332可以均设置有两个，在室内机空调的长度方向上，两个上部弧形齿条331靠近空调室内机的两侧设置，两个下部弧形齿条332也靠近空调室内机的两侧设置，与此同时，主动齿轮32可设置两个，或者主动齿轮32应当设置为长条形主动齿轮，以便其同时与左右两侧的第一中间齿轮34或第二中间齿轮35相啮合。
除此之外，本发明中还公开了一种空调室内机，包括前面板运动机构，该前面板运动机构为上述任意一实施例中所公开的前面板运动机构。
由于采用了上述前面板运动机构，因而该空调室内机兼具上述前面板运动机构相应的技术优点，本文中对此不再进行赘述。
本文中应用了具体个例对本发明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发明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，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
