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作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。
本发明的实施例提供一种降噪门,如图1所示为降噪门的结构示意图,包括:1个T形结构件201、两个扇型结构件202和1个门板203,T形结
构件201和扇型结构件202通过可拆卸的连接结构件(图中未示出)与门板203连接。其中,其中,T形结构件201位于门板203的中轴线处,两个扇形结构件202分别位于T形结构件201的两侧,箭头方向代表风向。
这样可通过改变扇形结构件202在门板203上的不同的安装位置和安装方式,得到不同的降噪门形式,能够满足不同的降噪效果和风道阻力的场合需求。例如还可以将图1的安装方式(流线型安装方式)中的扇形结构件202的位置左右调换,使得降噪门的安装效果如图2所示,即另一种降噪门的结构示意图(迷宫型安装方式)。
下面介绍T形结构件201、扇形结构件202与门板203的连接方式。
一种可连接的方式为:对于图1和图2中的T形结构件201和扇形结构件202与门板203的连接来说,如图3所示,为降噪门的门板203和T形结构件201或扇形结构件202的组装示意图。门板203包括有套筒部件401,所述T形结构件201和所述扇形结构件202分别包括有圆柱部件402,所述门板203与所述T形结构件201、所述门板203与所述扇形结构件202均通过所述套筒部件401和所述圆柱部件402连接,所述圆柱部件402的直径小于所述套筒部件401的直径。
这样,可先将T形结构件201或扇形结构件202往上抬,直到圆柱部件402的下沿高过套筒部件401的上沿,将T形结构件201或扇形结构件202靠近门板203,直到圆柱部件402的轴心与套筒部件401的轴心对齐,然后将T形结构件201或扇形结构件202放下,T形结构件201或扇形结构件202就可以安装在门板203上了。
其中,所述T形结构件201和所述扇形结构件202的材料可以为吸声材料,例如多孔性纤维材料等,本申请不做限定。
可以理解的是,另一种可连接的方式可以为:所述门板203包括有圆柱部件402,所述T形结构件201和所述扇形结构件202分别包括有套筒部件401,所述门板203与所述T形结构件201、所述门板203与所述扇形结构件202均通过所述套筒部件401和所述圆柱部件402连接,所述圆柱部件402的直径小于所述套筒部件401的直径。这样,连接安装时,可将门板203抬起,将门板203上的圆柱部件402***进T形结构件201或扇形结构件202的圆柱部件402内即可。
为了让T形结构件201和扇形结构件202可以稳当安装在门板203上,套筒部件401内侧壁设置有凹坑,所述圆柱部件402外侧壁设置有球状部件和弹簧403,且圆柱部件402为空心,所述球状部件404与所述弹簧403的一端连接,所述弹簧403的另一端固定在所述圆柱部件402的内侧壁,所述球状部件404的部分嵌设在所述凹坑中,即球状部件404的部分是凸出在圆柱部件壁外的。
也就是说,套筒部件401上有凹坑,圆柱部件402上相当于有一弹性小球,即圆柱部件402上的小球与弹簧403的一端连接,弹簧403的另一端固定在圆柱部件402的内壁上,当圆柱部件402***套筒部件401内部,且当外部施加一定的力后,圆柱部件402上的小球就会缩入圆柱部件402内部,转动T形结构件201或者扇形结构件202,当小球位置与套筒部件401内部的凹坑对齐时,小球就会弹出,起到限位作用。
可以理解的是,也可以是圆柱部件的外侧壁设置有凹坑,所述套筒部件401内侧壁设置有球状部件和弹簧,所述球状部件与所述弹簧的一端连接,所述弹簧的另一端固定在所述套筒部件的内侧壁,所述球状部件的部分嵌设在所述凹坑中。
此外,这里的凹坑的数量可以为至少一个,那么球状部件的数量与凹坑的数量相同,这样,当扇形结构件202需要改变角度时,只需要用力转动扇形结构件202,如果施加在球状部件上的力达到一定大小时,球状部件就会缩回圆柱部件402内部或者套筒部件401内部,调节扇形结构件的角度,直到合适的角度位置为止,例如将球状部件转动至了相邻的另一凹坑中。例如套筒部件401上存在凹坑,圆柱部件402上存在带弹簧的球状部件,凹坑和球状部件的数量为4个时,圆柱部件402***在套筒部件401内部后的横截面图如图4所示,即图1至图3中的T形结构件201、扇形结构件202与门板203通过圆柱部件402与套筒部件401连接后,圆柱部件402和套筒部件401的结构示意图。
进一步的,在使用相同的模具完成两组降噪门的部件的生产后,得到一种降噪门组合,这样可以使得制造成本降低。
再进一步的,在得到降噪门组合后,可以根据机柜***不同的阻力要求和降噪要求,可通过改变扇形结构件202的安装位置和安装方式,得到
不同降噪门形式,满足不同降噪效果和风道阻力的场合需求。
降噪门组合与机柜安装完成后的效果图可以如图5至图8所示(假设机柜501的风扇502在出风口处即后门处时),其中箭头方向表示风向。
具体地,如图5所示,进风口处(前门处)的降噪门和出风口处的降噪门流道均成流线型,阻力低,适合于对降噪门风力阻力要求小的场合;
如图6所示,进风口处的降噪门和出风口处的降噪门流道均成迷宫形,降噪效果大,适合于对降噪门降噪效果明显的场合;
如图7所示,进风口处的降噪门流道为迷宫形,出风口处的降噪门流道为流线型,适合于降噪效果较高、风力阻力较低的场合;
如图8所示,进风口处的降噪门流道为流线型,出风口处的降噪门流道为迷宫型,适合于风力阻力低、降噪效果较低的场合。
由于出风口处的风向都是向两边扩散的,在操作人员在后门处操作时,气流和噪声不会正对着操作人员,操作体验好。
当带有本发明的降噪门的机柜并柜时,一个降噪门需要打开,如果只需要一个人维护,开门的角度可以为90°,此时,T形结构件201的一端与最近处的门板203的一端的连线,与门板203的夹角可以为45°,开门后的效果图可以如图9所示。当然也可以小于45°。
如果需要两个人维护,开门角度可以达到120°或者其它角度时,可以将左侧的降噪门的右边的扇形结构件转动移动的角度,使得右侧的降噪门的角度可以打开120°或者其它角度,如图10所示,以方便两人维护。
当降噪门包装运输时,可以将降噪门的4个部分拆卸下来打包,可以减小包装体积,节省运输成本,如图11所示,由原本两个包装(左侧示意图)合并到一个包装(右侧示意图),使得包装体积减小。
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应以所述权利要求的保护范围为准。
最后应说明的是:以上实施例仅用以说明本发明的技术方案,而非对其限制;尽管参照前述实施例对本发明进行了详细的说明,本领域的普通
技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
