为了便于理解本申请,下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳的实施例。但是,本申请可以以许多不同的形式来实现,并不限于本文所描述的实施例。相反地,提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。
请参阅图1和图2,本申请提供一种门板机构,其可以安装在空调等制冷设备上。该 门板机构包括外壳1、门板2、固定部3和驱动部4。外壳1上设置有安装缺口11,安装缺口11即为门板2的安装位置处。具体地,可以使门板2和安装缺口11的形状相适,如二者均为平面结构或者均为弧形结构等,当然,二者还可以为相互适配的异形结构。可选地,门板2和安装缺口11均可以为圆柱侧面状结构。下文均以门板2和安装缺口11为弧形结构为例,作进一步限定和解释说明。在这种情况下,错位段31和齿条42均为弧形结构,导槽421的结构也可以根据实际情况对应适配;门板2和外壳1均可以采用塑料或金属等材料制成,且使二者的尺寸相适设计,以保证门板2与外壳1之间具有较好的连接效果。在门板机构的工作过程中,固定部3和驱动部4相配合,能驱动门板2相对外壳1运动。
详细地说,门板2通过固定部3和驱动部4安装于外壳1上,且在固定部3和驱动部4的作用下,使门板2在设定情况下能相对外壳1运动。门板2包括主体21和配合部22,配合部22连接在主体21上,主体21为圆弧面状结构。如图2所示,固定部3固定安装于门板2上,且固定部3上设置有第一滑道,第一滑道包括互相连接的错位段31和后退段32。驱动部4包括齿轮41和齿条42,且齿轮41和齿条42相互啮合,从而在齿轮41的作用下,使齿条42以自身旋转中心为圆心转动。齿条42上设置有导槽421,且错位段31的圆心与所述齿条42的前述旋转中心重合。在该门板机构的装配过程中,配合部22与第一滑道和导槽421均配合,一方面可以将门板2安装在固定部3和驱动部4上,另一方面,在齿轮41的作用下,还能使门板2相对外壳1运动,完成使安装缺口11打开或封堵的工作。
具体地,驱动部4和固定部3均可以采用塑料或金属等材料制成,且可以为齿轮41配设驱动电机,以为齿条42提供驱动力,齿轮41和齿条42上轮齿的模数以及齿宽等具体尺寸可以根据实际情况确定。配合部22可以设置有一个,也可以设置有多个,且可以使第一滑道和导槽421的数量均与配合部22的数量相同,并使配合部22与第一滑道和导槽421均对应配合。
更进一步地,第一滑道上设置错位段31的目的是,保证门板2能以齿条42的旋转中心为圆心相对外壳1旋转,从而使安装缺口11暴露出来。设置后退段32的目的是为门板2相对外壳1向外壳1的内部移动提供导向等作用,以使门板2和外壳1在错位段31的延伸方向上形成错位状态,保证门板2后续相对外壳1进行旋转动作能正常进行。因而,后退段32的延伸方向与门板2的两端之间连线相互垂直,以保证门板2能正常相对外壳1向外壳1的内侧平移,从而与外壳1形成相互错位的状态,并在齿轮41的作用下,再沿错位段31的延伸方向向安装缺口11的一侧移动,从而使安装缺口11被打开。
在门板机构的打开过程中,齿轮41转动,请参阅图3和图4,齿条42也随之转动, 可以先使配合部22沿着后退段32移动,与此同时,配合部22还从导槽421的一端移动到导槽421的另一端,因而导槽421的形状结构为配合部22的前述直线运动和整个导槽421相对配合部22进行的旋转运动的合运动。工作人员可以根据前述两个运动过程的实际情况,确定齿条42上导槽421的具体结构及尺寸以及延伸方向。请参阅图4和图5,齿轮41继续转动,在齿条42的带动下,配合部22继续沿着错位段31移动,从而使整个门板2从安装缺口11处移开,使安装缺口被完全打开。
为了提升门板2在相对外壳1运动的过程中的稳定性,可选地,配合部22可以设置有两个,两个配合部22可以沿错位段31的延伸方向间隔排布。对应地,固定部3上可以设置有两条第一滑道,齿条42上也可以设置有两条导槽421。显然地,两个第一滑道和两个导槽421的排布方向也为错位段31的延伸方向。在门板机构的装配过程中,两个配合部22分别与两条第一滑道和两条导槽421一一对应配合,这可以防止因门板2与固定部3和驱动部4之间,通过数量较少的配合部22相连接,而导致在门板2相对外壳1运动的过程中,门板2相对外壳1出现晃动现象,造成门板2的稳定性较低,甚至出现门板2以配合部22为圆心出现自转的情况,而不能相对外壳1进行整体转动的情况。需要说明的是,两个配合部22的具体结构和尺寸可以相同,也可以不同,但相互配合的配合部22、第一滑道和导槽421各自的结构和尺寸必须相互适配,以保证门板2相对外壳1的运动过程能正常进行。
可选地,在固定部3上设置有两个第一滑道的情况下,请参阅图6,可以使两个第一滑道上的错位段31的半径相等,从而在设计及制造固定部3及整个门板机构的过程中,可以在一定程度上减小固定部3的整体尺寸,节省用于安装固定部3所需空间的大小,在这种情况下,可以通过对应改变多个配合部22的具体结构以及设置位置,使多个配合部22能分别与上述这种结构的两个第一滑道均对应配合,从而保证门板机构的正常工作;另外,在设计两个第一滑道的过程中,如果空间有限,还可以使两个第一滑道部分重叠,或者使两个第一滑道的深浅程度不同。
从另一方面来说,在配合部22设置有两个的情况下,第一滑道和导槽421也可以均设置有两条,异于上一实施例中,两组驱动结构(包括固定部3和驱动部4)均设置在门板2的同一侧,本实施例中的两条第一滑道可以分别设置于门板2的相对的两侧,也即,固定部3可以设置有两个,两个固定部3上可以分别设置有至少一个第一滑道,相应地,齿条42也可以设置有两个,但齿轮41的数量可以无限制,其可以仅设置有一个,并通过该单个齿轮41同时驱动两个齿条42。当然,也可以设置有两个驱动部4,在这种情况下,两组前述驱动结构可以分别设置在门板2的相对两侧。显然地,门板机构采用上述实施例 所提供的这种结构形式时,也可以在一定程度上提升整个门板机构的运行稳定性。相应地,两个配合部22的结构可以相同,也可以不同,两个第一滑道的结构可以相同,也可以不同,两个导槽421的结构可以相同,也可以不同,此处不再一一赘述。
另外,在本申请所提供的门板机构中,即便在配合部22、第一滑道和导槽421均设置有单个的情况下,固定部3和驱动部4二者的相对位置也存在多种分布情况,至少分为二者可以设置在门板2的同一侧和异侧。详细地说,固定部3和驱动部4设置在门板2的同一侧时,可以使驱动部4上的导槽421沿齿条42的厚度方向贯穿齿条42设置,以使配合部22可以穿过导槽421,并与固定部3上的第一滑道相配合,在这种情况下,第一滑道可以为贯穿结构,也可以为有底的盲槽结构,此处不作限制。另一种组装方式为,使固定部3和驱动部4分别设置在门板2的相对两侧,在这种情况下,配合部22可以设置有两个,并使两个配合部22中的一者与第一滑道配合,另一者与导槽421配合,当然,固定部3和配合部22二者相对门板2的具体布置位置可以根据实际情况确定,在这种情况下,第一滑道和导槽421的结构可以根据实际情况确定,二者既可以均为有底的盲槽结构,也可以均为贯穿结构,或者一者为有底的盲槽结构,另一者为贯穿结构,本文对此不作限制。
可选地,如图2所示,第一滑道和导槽421均可以为贯穿结构,即可以使第一滑道沿固定部3的厚度方向贯穿固定部3设置,且使导槽421沿齿条42的厚度方向贯穿齿条42设置,以在门板机构的装配过程中,使配合部22可以同时穿过导槽421和第一滑道,这可以进一步提升门板2、固定部3和驱动部4三者之间配合关系的稳定性,从而保证本申请所提供的门板机构在工作过程中的可靠性。
一实施例中,如图1所示,配合部22可以设置有四个,四个配合部22中,两两成组,固定部3和齿条42均可以设置有两个,且任一固定部3上均设置有两个第一滑道,并与一组配合部22相配合,任一齿条42上也均设置有两个导槽421,并与一组配合部22对应配合,在这种情况下,任一导槽421均可以设置成贯穿结构,以保证配合部22能穿过导槽421与第一滑道配合。本申请所提供的门板机构在采用上述这种具体结构时,稳定性更高,结构也较为简单,成本及控制难度相对较低,具有较好的整体性能。
进一步地,沿错位段31的延伸方向,还可以使错位段31跨过的角度大于安装缺口11所跨过的角度,从而在门板机构的运动过程中,门板2可以在驱动部4的作用下,从与安装缺口11互相封堵的状态变为使安装缺口11暴露开来的状态,且由于错位段31跨过的角度大于安装缺口11跨过的角度,从而可以保证在配合部22自错位段31的一端移动到错位段31的另一端之后,门板2能完全从与安装缺口11相对的位置处移开,防止门板2运动到最末端之后,其仍对安装缺口11产生一定的阻挡作用,保证安装缺口11的打开程度能 达到最大状态。
进一步地,为了保证包括本申请所提供的门板机构的空调在不工作时,门板2与外壳1之间具有较好的密封效果,可选地,如图3所示,可以使外壳1和主体21均为圆弧状结构,且使门板2上与外壳1相配合的两个侧面相对门板2的径向倾斜设置,或者说,使所述门板2的外侧面的弧长小于所述门板2的内侧面的弧长,相对应地,使外壳1的外侧面的弧长大于外壳1的内侧面的弧长,这可以使外壳1和门板2在前述径向上限位配合,一方面可以使门板2和外壳1之间具有较好的密封效果,另一方面,还可以防止门板2在封堵外壳1的安装缺口11的过程中,因意外而越过安装缺口11而相对外壳1伸出,而不能与安装缺口11相配合。
进一步地,如图2和图6所示,本申请所提供的门板机构中,错位段31和后退段32之间可以通过圆角过渡段33相连接,从而使得错位段31与后退段32之间的过渡更圆滑,从而在配合部22移动的过程中,配合部22可以较为平缓地借助圆角过渡段33,在后退段32和错位段31之间相互切换,进而防止门板2在移动过程中出现幅度较大的震动或卡滞现象,保证门板机构工作过程的正常有序进行。具体地,圆角过渡段33的尺寸可以根据后退段32和错位段31的实际情况灵活设计。
进一步地,配合部22可以包括连接段221和卡持段222,连接段221的一端与主体21相连接,卡持段222连接在连接段221的另一端,且沿错位段31的轴向延伸,卡持段222可以为圆柱状结构,从而进一步提升配合部22与第一滑道和导槽421相配合时的可靠性以及顺畅性。具体地,卡持段222的直径可以稍小于与之配合的第一滑道和/或导槽421的宽度,卡持段222和连接段221可以采用一体成型的方式形成,以提升二者之间的连接可靠性,进而保证本申请所提供的门板机构的整体性能。
基于上述任一实施例所提供的门板机构,本申请的第二方面还提供一种空调,其包括上述任一门板机构。
