本发明主要提出一种空调面板,主要应用于空调器中,以增加空调面板的密封性能。当然,该空调面板还可以用于其它家用电器,如冰箱、冰柜、酒柜、风扇、电饭煲、热水壶、破壁机、挂烫机、净化器以及加湿器等。
以下将主要描述空调面板100的具体结构。
参照图1至图7,在本发明实施例中,该空调面板100用于具体壳体的空调器,所述空调面板100与所述壳体固定连接,所述空调面板100包括:
金属基板130,所述金属基板130上设有显示区110,所述显示区110上开设有若干的透光孔120;透光防护层140,所述透光防护层140覆盖在所述金属基板130背向所述壳体的板面上。
具体地,本实施例中,空调器以壁挂式空调器为例,壁挂式空调器包括壳体,壳体具有进风口、出风口和连通进风口和出风口的风道。进风口设置在壳体的顶部或者背面(使用时背向用户),出风口开设在壳体的正面(使用时面向用户)。空调面板100设置在出风口上方的壳体上。空调面板100包括金属基板130,金属基板130的材质可以有很多,可以为不锈钢、铝以及钢等;当然,在一些特殊情况下,不排除使用贵重金属,如金、银等;当然,在一些实施例中,金属基板130也可以由钢、铝、不锈钢等合金材质制成。空调面板100的形状与壳体正面的形状适配,例如,当壳体正面为长方形时,空调面板100也为长方形。壳体上安装有显示当前室内温度、目标温度等的显示灯,和提示空调器当前工作状态的工作提示灯等。金属基板130上的显示区110对应上述的显示灯和提示灯设置。在显示区110上,通过激光穿孔工艺,或者钻孔工艺等开设有若干的透光孔120,透光孔120可以布满整个显示区110,当然也可以仅对应显示灯和提示灯排布,以减少开孔数。透光孔120的孔径在此不作特殊限定,可以为大孔径孔(参照图1和图2),如φ0.3mm-0.5mm,也可以为较小的孔径(参照图3至图7),例如φ0.01mm-0.07mm,当然,该孔径可选为φ0.03mm-0.05mm。
透光防护层140,所述透光防护层140覆盖在所述金属基板130背向所述壳体的板面上。透光防护层140由透明材质制成,透明材质可以为PVC(聚氯乙烯Polyvinyl chloride)、PET(聚对苯二甲酸乙二醇酯是热塑性聚酯中最主要的品种,英文名为Polyethylene terephthalate 简称PET),俗称涤纶树脂。透光防护层140与金属基板130的板面贴合,封堵透光孔120,避免水、灰尘等穿过透光孔120进入空调器内。其中,值得说明,透光孔120孔径的大小,影响透光防护层140的强度,当透光孔120孔径太大时,透光防护层140对应透光孔120的部分得不到支撑,容易损坏。
本实施例中,当空调器受到外部水侵袭时,空调面板100的透光防护层140,将水流阻挡在金属面板的外部,使得水不能从空调器外部通过透光孔120进入空调器内,同时,使得颗粒、灰尘、以及外部的杂物也难以进入空调器内,从而有利于空调器稳定的工作;由于增加了透光防护层140,使得金属基板130得到多一层保护,可避免水、氧气等腐蚀成分对金属基板130进行腐蚀,有利于提高金属基板130的使用寿命;由于透光防护层140的设置,使得空调面板100的表面不会留下任何用户通过肉眼可观察到的加工痕迹,大幅的提高了空调面板100的外观效果,使得空调面板100更加美观大方。
为了提高空调器显示灯的显示效果,所述透光防护层包括141和镶嵌于所述141内的若干玻璃微珠142。
当显示灯工作时,显示灯的光线穿过透光孔后,照射在玻璃微珠142上,玻璃微珠142对光进行折射和散射,使得经过玻璃微珠142后的光线更多,光线的偏转角度增加,从而使得光线照射范围增加,光线的亮度增加,从而增加了用户观看显示内容的视角,从而更加有利于用户对显示内容的观看。
为了进一步增加用户观看显示内容的效果,所述141的厚度为38μm~250μm,所述玻璃微珠142的粒径为8~35μm。其中,141的厚度以38μm~98μm为例,玻璃微珠142可以全部镶嵌于141内部,避免玻璃微珠142在外力作用下脱落。玻璃微珠142均匀的分布在141内,当然,也可以根据实际情况,排布形成需要的形状。为了进一步提高显示效果,所述玻璃微珠142的折射率为2.3~3.2,圆度≥95%。当玻璃微珠142的粒径在10μm左右时,玻璃微珠142的折射率比较适合空调的显示要求。通过将折射率和圆度的设置,使得玻璃微珠142的散射和折射效果更好,使得光线照射范围增加,光线的亮度增加,从而增加了用户观看显示内容的视角,从而更加有利于用户对显示内容的观看。
为了增加空调面板的强度和改进空调面板的外观,所述透光防护层还包括金属薄膜层144和聚氨酯层143,所述聚氨酯层143覆盖在所述141的表面,所述金属薄膜层144覆盖在所述聚氨酯层143的表面;
所述金属薄膜层144对应所述显示区域开设有避让缺口145。
本实施例中,金属薄膜层144的材质可以有很多,如铝,不锈钢等,本实施例中以铝为例。聚氨酯层143设置在金属基板和金属薄膜层144之间,金属薄膜层144覆盖在聚氨酯层143比对金属基板的侧面上。通过聚氨酯层143和金属薄膜层144的设置,增加了空调面板的强度,同时,通过金属薄膜层144的设置,使得空调面板的质感更好,有利于大幅提升空调面板的外观,使其更加美观、大气。
为了减少激光冲孔的数量,提高冲孔效率,若干的所述透光孔排列形成文字和/或图案。
其中,图案可以为电源键图案、加热图案、制冷图案、除湿图案、送风图案等。文字则以双8字为例。即,若干的所述透光孔120排列形成并列的两个8字。通过将透光孔120排列呈“88”形,使得在满足所有数字显示的前提下,尽可能的减少冲孔的数量。从而可以提高制造空调面板100的效率。在激光冲孔的过程中,先将8字分割成上、中、下三个横向条和两上和两下四条纵向条,每一横向条和纵向条分别单独加工。冲孔时,从横向条或纵向条从条的一端开始,沿横向条或纵向条的宽度方向冲孔,当当前宽度方向冲孔完成后,沿条的长度方向前进一个孔位,即呈之子形顺序开设。如此设置冲孔顺序,有利于提高透光孔120的冲孔效率,有利于提高空调面板100的加工效率。
为了减少玻璃微珠142的数量,同时提高空调器的显示内容的显示效果,若干的所述玻璃微珠142对应所述文字和/或图案排列。通过将玻璃微珠142对应图案或者文字设置,使得从透光孔内射出的光线按照图案或者文字的轮廓折射和散射,使得自空调面板显示出的图案和文字更加凸出,显示效果更好。
为了提高空调面板100的强度和稳定性,所述空调器包括壳体,所述空调面板100与所述壳体固定连接,所述空调面板100还包括加强筋层,所述加强筋层覆盖在所述金属基板的正面上,所述透光孔120贯穿所述加强筋层。其中,所述加强筋层由若干的沿所述金属基板的长度方向延伸的加强筋组合而成;所述加强筋层覆盖在所述金属基板的表面。
具体地,本实施例中,在金属面板背对壳体的板面上设置加强筋层的方式可以有多种,如直接在金属面板上进行加强筋加工工艺,当然,也可以在金属面板上贴附加强筋层。不论使用何种方式实现加强筋层的形成,具有加强筋层后的空调面板100都比原有的面板强度要高,使得空调面板100的金属基板受到保护,同时,加强筋层也为透光孔120阻挡了很多外部的杂物,使得激光可少受外部环境的影响,也使得空调器少受外部环境的影响,从而有利于提高空调器使用的稳定性。当然,也使得空调面板100更加美观大方。
为了提高空调面板100的强度和稳定性,所述空调面板100还包括氧化层,所述氧化层覆盖在所述加强筋层背对所述金属基板侧面上,所述透光孔120贯穿所述氧化层。
具体地,本实施例中,在加强筋层背对金属面板面上设置氧化层的方式可以有多种,如直接在加强筋层上进行氧化工艺,当然,也可以在加强筋层上贴附氧化膜。不论使用何种方式实现加强筋层的形成,具有加强筋层后的空调面板100都比原有的面板强度要高,使得空调面板100的金属基板受到保护,同时,氧化层可以防止外部对金属面板的腐蚀。氧化层也为透光孔120阻挡了很多外部的杂物,使得激光可少受外部环境的影响,也使得空调器少受外部环境的影响,从而有利于提高空调器使用的稳定性。当然,也使得空调面板100更加美观大方。
为了显示区强度和显示效果的统一,所述透光孔的孔径φ与所述显示区所对应的所述金属基板的厚度d之间满足关系:
3 d /50≤φ≤d/10;
其中,0.2mm≤d≤0.6mm。
具体地,本实施例中,空调面板100包括金属基板,金属基板的材质可以有很多,可以为不锈钢、铝以及钢等;当然,在一些特殊情况下,不排除使用贵重金属,如金、银等;当然,在一些实施例中,金属基板也可以由钢、铝、不锈钢等合金材质制成。空调面板100的形状与壳体正面的形状适配,例如,当壳体正面为长方形时,空调面板100也为长方形。壳体上安装有显示当前室内温度、目标温度等的显示灯,和提示空调器当前工作状态的工作提示灯等。金属基板上的显示区110对应上述的显示灯和提示灯设置。在显示区110上,通过激光穿孔工艺开设有若干的透光孔120,透光孔120可以布满整个显示区110,当然可以仅对应显示灯和提示灯排布。
为了更好的开设透光孔120,所述显示区110所对应的所述金属基板的厚度d为0.2-0.6mm。在通过激光开设透光孔120的过程中,金属基板的厚度限制至透光孔120的孔径大小和甚至影响到能否击穿。当金属基板的厚度较大时,激光不能冲击出较小的透光孔120,甚至,当金属基板的厚度达到一定数值时,激光难以击穿;当金属基板的厚度太小时,空调面板100的强度难以得到保证。因此,金属基板的厚度是非常关键和重要的参数。可选的,可以将显示区所对应的金属基板的厚度d设置为0.3mm-0.5mm。上述数据是发明人经过大量的实验和计算所获得,上述尺寸范围内的金属基板既可以保证空调面板100的强度,也可以保证激光可以透光孔的开设。此时,金属基板其它位置的厚度D为1.0mm或者3.0mm等,当然也可以根据实际需求进行调整。
同时,为了提高空调面板100的透光性和防水性的结合性能,所述透光孔120的孔径与所述金属基板显示区110的厚度之比为3/50-1/10,
即,当显示区110对应的金属基板的厚度d为0.2mm时,透光孔120的孔径φ为0.012mm-0.02mm;当显示区110对应的金属基板的厚度d为0.6mm时,透光孔120的孔径φ为0.02mm-0.06mm;当显示区110对应的金属基板的厚度d为0.3mm时,透光孔120的孔径φ为0.018mm-0.03mm;当显示区110对应的金属基板的厚度d为0.5mm时,透光孔120的孔径φ为0.03mm-0.05mm。上述透光孔120的孔径既可以有效的保证空调面板100的防水性能,同时,又可以有效的保证透光孔120的透光性。
为了更加简洁的对本发明的工作原理和效果进行描述,透光孔120的孔径以φ0.03mm-0.05mm为例。
将透光孔120的孔径设置为φ0.03mm-0.05mm,使得水在穿过透光孔120时,受到较大的附着力,附着力来自于液体之间的相互摩擦,也来自于液滴与透光孔120的孔壁之间的摩擦。由于透光孔120的孔径很小,使得液体与液体之间的附着力和液体与孔壁之间的附着力可以承受一定的水压,该可承受的水压远远大于空调器在使用过程中容易碰到工况下的水压,即在正常的使用过程中,水不能穿过透光孔120进入壳体内;同时,由于将显示区所对应的金属基板的厚度设置为0.2~0.6mm,使得显示区的承载强度得到有效的保证。
本实施例中,当空调器受到外部水侵袭时,空调面板100上的透光孔120孔径小,其对水的承载能力大于水的水压,使得侵袭的水不能通过透光孔120,从而防止了水通过透光孔120进入空调器内;同时,由于透光孔120的孔径如此之小,使得一般的颗粒、灰尘、以及外部的杂物也难以进入空调器内;从而,将透光孔120的孔径设置为φ0.03mm-0.05mm有利于提高空调面板100的防水能力,有利于空调器稳定的工作;由于透光孔120为通孔,在孔内没有设置任何障碍物,使得壳体内部提示灯和显示灯的光线可以直接(以最高透光率)穿过透光孔120而进入人的眼睛里,有利于提高空调面板100的透光性,即使得空调面板100的透光性和防水性有机的结合在一起;由于透光孔120的孔径小,使得金属面板的表面不会留下任何用户通过肉眼可观察到的加工痕迹,大幅的提高了空调面板100的外观,被称为会发光的金属面板;同时,由于将显示区所对应的金属基板的厚度设置为0.2~0.6mm,使得显示区的承载强度得到有效的保证;即本发明的空调面板集面板的整体性、防水防尘性、承载强度以及美观于一身。
为了进一步提高空调面板显示区的强度,若干的所述透光孔排列成若干行,相邻两行的所述透光孔交错设置。
同一行的相邻两所述透光孔的中心距d1与所述透光孔的孔径φ之间满足关系:
5φ≤d1≤10φ。
相邻两行的相邻两所述透光孔的中心距d2与所述透光孔的孔径φ之间满足关系:
3φ≤d2≤8φ。
本实施例中,为了提高空调面板100的强度,同一行相邻两所述透光孔120之间的间距d1大于或者等于所述透光孔120的孔径的5倍,且小于或者等于所述透光孔120的孔径的10倍。d1以0.2mm为例,d2以0.14mm为例。相邻两行的相邻两所述透光孔的中心距d2大于或者等于所述透光孔120的孔径的4倍,且小于或者等于所述透光孔120的孔径的8倍。上述关系是申请人经过大量的实验,花费大量的时间、人力和物力得。总的来说,相邻两个透光孔120之间的距离d1和d2,不能太大,也不能太小,当间距太大时,显示灯和提示等透过透光孔120的光线的量有限,影响用户的观看,当间距太小时,影响空调面板100显示区110的强度。上述透光孔120之间的间距既可以有效的保证空调面板100的抗形变强度,同时,又可以有效的保证透光孔120的透光性。
为了提高射出空调器的关系的柔和度,所述透光孔120自所述空调器内向外呈渐扩设置。透光孔120的孔径从显示灯或提示灯的一侧向外部逐渐增加,以锥形孔为例,当光线从提示灯或显示灯到外部时,呈渐扩散的形式射出。从而向外射出的光面面积增加,使得用户的感光面积增加,有利于用户的观看;同时由于孔径小,孔的密度较大,使得空调面板100上的感光点较多,高密度的感光点相互复合,使得进入用户眼中的光为复合光,复合光相较于单一光源的光线更加柔和饱满,使得用户可以接收到更加柔和饱满的光线,有利于提高用户观看提示灯和显示灯的舒适感。
当然,在一些实施例中,在透光孔120内还可以添加透明密封胶,在进一步增加激光孔的密封性的同时,锥形孔内的密封胶使得光线进一步扩散,有利于多个透光孔120之间的光线更加充分的复合,使得光线更加柔和饱满,光源,使得用户的感光体验更好,更舒适。
本发明还提出一种空调器,该空调器包括壳体和空调面板100,该空调面板100的具体结构参照上述实施例,由于本空调器采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有有益效果,在此不再一一赘述。其中,所述壳体具有进风口、出风口以及连通所述进风口和所述出风口的风道;述空调面板100对应所述出风口与所述壳体固定连接。
本发明还提出一种空调面板的制造方法,包括以下步骤:
在金属基板上开设显示区,所述显示区对应的金属基板的厚度d为0.2-0.6mm;
在激光开设激光微孔120的过程中,金属基板的厚度限制至激光微孔120的孔径大小和甚至影响到能否击穿。当金属基板的厚度较大时,激光不能冲击出较小的激光微孔120,甚至,当金属基板的厚度达到一定数值时,激光难以击穿;当金属基板的厚度太小时,空调面板100的强度难以得到保证。因此,金属基板的厚度是非常关键和重要的参数。可选的,可以将金属基板的厚度设置为0.3mm-0.5mm。上述数据是发明人经过大量的实验和计算所获得,上述尺寸范围内的金属基板既可以保证空调面板100的强度,也可以保证激光可以微孔的开设。显示区110对于空调器的提示灯和显示灯设置,显示区110的作用在于使得显示灯和提示灯所显示的内容,可以隔着空调面板100显示给用户。因此,一般情况下,显示区110的厚度比空调面板100的厚度薄。显示区110的金属基板的厚度可以通过车、刨、磨等工艺来实现,当然,也可以通过使用化学试剂,将显示区110的厚度调节为预设的厚度。
对金属基板进行表面拉丝处理;
拉丝工艺是一种金属加工工艺。在金属压力加工中。在外力作用下使金属强行通过模具,金属横截面积被压缩,并获得所要求的横截面积形状和尺寸的技术加工方法称为金属拉丝工艺。可以理解的是,拉丝也可以是采用拉丝的布条往复运动,在工件表面来回摩擦使工件表面光洁度提高的一种方法,表面的纹理呈直线状。可以提高表面质量,遮掩表面轻微划痕。本申请以在金属基板板面上进行拉丝处理为例,当然,可以将拉丝后的膜片贴附于金属板面上,来实现金属基板的拉丝效果。
对拉丝后的金属基板进行氧化处理;
在拉丝层上通过加热或化学试剂处理,在拉丝层表面形成氧化层。氧化层的化学稳定性比金属基板高,即氧化层不易被腐蚀,使得金属基板的稳定性得到提高。金属钝化理论认为,钝化是由于表面生成覆盖性良好的致密的钝化膜。大多数钝化膜是由金属氧化物组成,因此钝化膜又称为氧化膜。如铁钝化膜为γ-Fe2O3,Fe3O4,铝钝化膜为无孔的γ-Al2O3等。氧化膜厚度一般为10-9~10-10m。
将透光防护层覆盖至所述氧化处理后的金属基板表面。
将透光防护膜覆盖在金属基板130氧化的一层,设置有透光防护膜的一侧为空调面板100的正面。透光防护层140由透明材质制成,透明材质可以为PVC(聚氯乙烯Polyvinyl chloride)、PET(聚对苯二甲酸乙二醇酯是热塑性聚酯中最主要的品种,英文名为Polyethylene terephthalate 简称PET),俗称涤纶树脂。透光防护层140与金属基板130的板面贴合,封堵透光孔120,避免水、灰尘等穿过透光孔120进入空调器内。其中,值得说明,透光孔120孔径的大小,影响透光防护层140的强度,当透光孔120孔径太大时,透光防护层140对应透光孔120的部分得不到支撑,容易损坏。
本实施例中,当空调器受到外部水侵袭时,空调面板100的透光防护层140,将水流阻挡在金属面板的外部,使得水不能从空调器外部通过透光孔120进入空调器内,同时,使得颗粒、灰尘、以及外部的杂物也难以进入空调器内,从而有利于空调器稳定的工作;由于增加了透光防护层140,使得金属基板130得到多一层保护,可避免水、氧气等腐蚀成分对金属基板130进行腐蚀,有利于提高金属基板130的使用寿命。
在金属基板上开设显示区,所述显示区对应的金属基板的厚度d为0.2-0.6mm;该透光孔的孔径φ与所述显示区所对应的所述金属基板的厚度d之间满足关系:
3 d /50≤φ≤d/10。
光是从组成物质的原子中发射出来的,原子获得能量后处于不稳定状态(也就是激发状态),它会以光子的形式把能量发射出去。而激光,就是被引诱(激发)出来的光子队列,这光子队列中的光子们,光学特性一样,步调极其一致。激光对氧化处理后的金属基板进行冲孔处理,在冲击之前,对激光光速进行功率和直径调节。通过调节激光光束的直径和功率,来调整激光微孔120的孔径,当然,孔径为0.03-0.05mm,允许存在公差范围内的误差。
当显示区110对应的金属基板的厚度d为0.2mm时,透光孔120的孔径φ为0.012mm-0.02mm;当显示区110对应的金属基板的厚度d为0.6mm时,透光孔120的孔径φ为0.02mm-0.06mm;当显示区110对应的金属基板的厚度d为0.3mm时,透光孔120的孔径φ为0.018mm-0.03mm;当显示区110对应的金属基板的厚度d为0.5mm时,透光孔120的孔径φ为0.03mm-0.05mm。上述透光孔120的孔径既可以有效的保证空调面板100的防水性能,同时,又可以有效的保证透光孔120的透光性。
通过该工艺制造的空调面板,当空调器受到外部水侵袭时,空调面板100上的透光孔120孔径小,其对水的承载能力大于水的水压,使得侵袭的水不能通过透光孔120,从而防止了水通过透光孔120进入空调器内;同时,由于透光孔120的孔径如此之小,使得一般的颗粒、灰尘、以及外部的杂物也难以进入空调器内;从而,将透光孔120的孔径设置为φ0.03mm-0.05mm有利于提高空调面板100的防水能力,有利于空调器稳定的工作;由于透光孔120为通孔,在孔内没有设置任何障碍物,使得壳体内部提示灯和显示灯的光线可以直接(以最高透光率)穿过透光孔120而进入人的眼睛里,有利于提高空调面板100的透光性,即使得空调面板100的透光性和防水性有机的结合在一起;由于透光孔120的孔径小,使得金属面板的表面不会留下任何用户通过肉眼可观察到的加工痕迹,大幅的提高了空调面板100的外观,被称为会发光的金属面板;同时,由于将显示区所对应的金属基板的厚度设置为0.2~0.6mm,使得显示区的承载强度得到有效的保证;即本发明的空调面板集面板的整体性、防水防尘性、承载强度以及美观于一身。
在一些实施例中,为了工艺的排布,可以将部分工艺之间的顺序进行调节,若所述使用激光在所述显示区开设透光孔的步骤,在所述对金属基板进行表面拉丝处理的步骤之前执行;
则在所述使用激光在所述显示区开设透光孔的步骤之前还包括:
向透光孔中填充可熔性胶状体。
为了避免在拉丝或氧化工艺过程中将激光微孔120封堵,向微孔中填充可熔性胶状体。
本实施例中,可熔性胶体可以为石蜡、水溶性好的胶体等。通过向微孔中填充可熔性胶体,将微孔封堵,避免拉丝和氧化工艺过程中,有金属微粒将微孔封堵。在对空调面板100进行拉丝、氧化处理后,再将位于微孔中的可熔性胶体熔化,以使微孔贯通。通过在对金属基板的表面拉丝处理之前向微孔中填充可熔性胶状体,避免金属微粒封堵微孔,避免后续通过复杂的工艺来贯通微孔,有利于提高空调面板100的制造效率。
为了进一步缩小激光微孔120的孔径,在所述对金属基板使用激光开透光孔的步骤之后还包括:
对金属基板进行辊压处理,以缩小所述透光孔的孔径。
具体地,辊压处理的方式有很多,可以使用一个辊轮和一个压板或者压杆来实现,本申请中的辊压以两个辊轮相对转动(一个辊轮按顺时针转动时,另一个辊轮按照逆时针转动)为例。调节两个辊轮之间的间隔,该间隔与显示区110的厚度对应,即该距离略微小于显示区110的厚度。例如,当显示区110的厚度为0.3mm时,两个辊轮之间的间距为0.295mm-0.0298mm。通过两个辊轮的相向滚动,使显示区110的空调面板100挤压延伸,以进一步挤压激光微孔120,使得激光微孔120的孔径进一步减小。从而进一步提高激光微孔120的防水性能,有利于提高空调面板100的防水性能。
为了提高空调面板100的防水性能,在所述对拉丝后的金属基板进行氧化处理的步骤之后还包括:
向所述微孔中填充透明密封胶。透明密封胶具有透光性、耐腐蚀性、疏水性,如环氧树脂、聚氨酯等。透明密封胶的填充方式以通过胶刷挤压进入激光微孔120为例。首先将透明密封胶倒到显示区110内,再用胶刷将密封胶均匀的刷到激光微孔120所排列的形状(双8)上,在刷胶的过程中,使用胶刷来回刷匀,以将密封胶挤压如激光微孔120内,以使每个激光微孔120内都填充有密封胶。在刷完胶后,将显示区110进行烘烤处理,以使密封胶快速的凝固雨激光微孔120内。烘干后,将显示区110内多余的密封胶刮除。
当然,在一些实施例中,如果在此之前已经在微孔中填充有可熔性胶状体,则需先融化可熔性胶状体后再向微孔中填充透明密封胶。
为了提高感光效果,将激光微孔120开设呈锥形孔,所述使用激光在所述显示区开设透光孔的步骤具体包括:
将激光束的功率调整为第一功率、激光束的直径调整为第一刃径,使用激光束冲击金属基板,以在金属基板上形成凹槽;
将激光束的功率调整为第二功率、激光束的直径调整为第二刃径,使用激光束冲击凹槽,以击穿凹槽底壁形成孔径逐渐缩小的所述透光孔;其中,第一功率小于第二功率,第一刃径大于第二刃径。
具体地,本实施例中,在激光开孔的过程中,激光的功率影响激光微孔120的孔深(功率越高孔深越深),激光光束的刃径影响激光微孔120的孔径(刃径越大孔径越大)。将激光束的功率调整为第一功率、激光束的直径调整为第一刃径,使用激光束冲击金属基板,以在金属基板上形成凹槽,凹槽形成于空调面板100朝向壳体的一侧。在将激光束的功率调整为第二功率、激光束的直径调整为第二刃径后,使用激光束从空调面板100的凹槽侧冲击凹槽,以击穿凹槽底壁形成孔径逐渐缩小的所述微孔,微孔贯穿空调面板100。
当光线从提示灯或显示灯到外部时,呈渐扩散的形式射出。从而向外射出的光面面积增加,使得用户的感光面积增加,有利于用户的观看;同时由于孔径小,孔的密度较大,使得空调面板100上的感光点较多,高密度的感光点相互复合,使得进入用户眼中的光为复合光,复合光相较于单一光源的光线更加柔和饱满,使得用户可以接收到更加柔和饱满的光线,有利于提高用户观看提示灯和显示灯的舒适感。
当然,在一些实施例中,在激光微孔120内还可以添加透明密封胶,在进一步增加激光孔的密封性的同时,锥形孔内的密封胶使得光线进一步扩散,有利于多个激光微孔120之间的光线更加充分的复合,使得光线更加柔和饱满,光源,使得用户的感光体验更好,更舒适。
为了提高显示区的强度,所述使用激光在所述显示区开设透光孔的步骤具体包括:
在所述显示区内按行开设所述透光孔;
其中,相邻两行的所述透光孔交错设置,同一行的相邻两所述透光孔的中心距d1与所述透光孔的孔径φ之间满足关系:
5φ≤d1≤10φ;
相邻两行的相邻两所述透光孔的中心距d2与所述透光孔的孔径φ之间满足关系:
3φ≤d2≤8φ。
本实施例中,为了提高空调面板100的强度,同一行相邻两所述透光孔120之间的间距d1大于或者等于所述透光孔120的孔径的5倍,且小于或者等于所述透光孔120的孔径的10倍。d1以0.2mm为例,d2以0.14mm为例。相邻两行的相邻两所述透光孔的中心距d2大于或者等于所述透光孔120的孔径的4倍,且小于或者等于所述透光孔120的孔径的8倍。上述关系是申请人经过大量的实验,花费大量的时间、人力和物力得。总的来说,相邻两个透光孔120之间的距离d1和d2,不能太大,也不能太小,当间距太大时,显示灯和提示等透过透光孔120的光线的量有限,影响用户的观看,当间距太小时,影响空调面板100显示区110的强度。上述透光孔120之间的间距既可以有效的保证空调面板100的抗形变强度,同时,又可以有效的保证透光孔120的透光性。
以上所述仅为本发明的优选实施例,并非因此限制本发明的专利范围,凡是在本发明的发明构思下,利用本发明说明书及附图内容所作的等效结构变换,或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
