Description

轴承组件及具有其的空调器 技术领域
本发明涉及空调技术领域，具体而言，涉及一种轴承组件及具有其的空调器。
背景技术
目前在空调技术领域，空调器的送风装置一般是通过轴承组件进行固定。轴承组件包括轴承座和轴承套，为了便于将轴承套装配到轴承座中，轴承套与轴承座之间具有间隙。然而，由于间隙的存在，使用空调器时会在轴承组件的间隙位置发生漏风的问题。漏风会导致空调器的风道内产生水珠，从而降低空调器的可靠性。
发明内容
本发明提供一种轴承组件及具有其的空调器，以解决现有技术中的轴承组件漏风的问题。
为了解决上述问题，根据本发明的一个方面，本发明提供了一种轴承组件，轴承组件包括：轴承座；轴承套，设置在轴承座内，轴承套包括相互连接的第一套段和第二套段，第一套段和轴承座之间具有间隙；密封结构，设置在第二套段与轴承座之间。

进一步地，密封结构还包括：引导段，引导段环绕设置在第二套段的外表面，引导段位于第一套段和密封段之间，引导段的横截面的直径沿第一套段至第二套段的方向逐渐增大。
进一步地，密封段的横截面的直径大于或等于轴承座的内表面的直径。
进一步地，轴承套还包括：筋条，沿第一套段的轴线方向设置在第一套段的外表面上；筋条为多个，多个筋条沿第一套段的圆周方向间隔设置，间隙设置在第一套段的外表面位于相邻两个筋条之间的部分与轴承座的内表面之间。
进一步地，轴承座的材质为橡胶或塑料，轴承套的材质为橡胶或塑料。
进一步地，轴承套与密封结构为一体式结构。
进一步地，轴承座与轴承套之间具有卡接结构。
进一步地，卡接结构包括：凸起，设置在轴承座的内侧；凹槽，设置在第一套段的外侧，凸起与凹槽配合连接。
进一步地，轴承套具有腔体，腔体位于第一套段内和/或第二套段内，轴承组件还包括：轴承，设置在腔体内，轴承用于支承空调器的送风装置。
根据本发明的另一方面，提供了一种空调器，包括底壳、送风装置和轴承组件，送风装置通过轴承组件可转动地设置在底壳上，其中，轴承组件为上述提供的轴承组件。
进一步地，轴承组件的轴承座与底壳固定连接，送风装置包括：两个连接板；多个叶片，多个叶片间隔设置在两个连接板之间；转轴，与两个连接板中的至少一个连接，转轴的一端与轴承组件的轴承配合连接。
进一步地，轴承组件的密封结构设置在轴承组件的轴承套靠近送风装置的一端。
应用本发明的技术方案，由于轴承套的第一套段与轴承座之间具有间隙，因此可以方便地将第一套段插入到轴承座中，在第一套段的引导下第二套段也便于插入到轴承座中，从而将轴承套装配到轴承座上。由于轴承组件还具有密封结构，当轴承套装配到轴承座上之后，密封结构能够将轴承套两侧的空间隔离，这样气体就不能通过第一套段与轴承座之间的间隙造成漏风。因此本发明的技术方案能够解决现有技术中的轴承组件漏风的问题。

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。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。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。
如图1至图3所示，本发明的实施例提供了一种轴承组件，该轴承组件包括轴承座10和轴承套20，轴承套20可拆卸地设置在轴承座10内。轴承套20包括相互连接的第一套段21 和第二套段22，第一套段21和轴承座10之间具有间隙。密封结构30设置在第二套段22与轴承座10之间，密封结构30能够起到密封作用。
应用本实施例的技术方案，由于轴承套20的第一套段21与轴承座10之间具有间隙，因此可以方便地将第一套段21插入到轴承座10中。在第一套段21的引导下第二套段22也可以方便地插入到轴承座10中，从而将轴承套20装配到轴承座10上。由于轴承组件还具有密封结构30，当轴承套20装配到轴承座10上之后，密封结构30能够将轴承套20两侧的空间隔离，这样可以避免气体通过第一套段21与轴承座10之间的间隙而造成漏风。因此本实施例的技术方案能够解决现有技术中的轴承组件漏风的问题。将该轴承组件应用于空调器的送风装置中，可以避免因为漏风而在空调器的风道内产生水珠的问题，从而提高了空调器的可靠性。
具体地，密封结构30包括密封段31，密封段31环绕设置在第二套段22的外表面，密封段31的横截面的直径的最大值大于第一套段21的横截面的直径的最大值。如此设置能够以简单的结构实现密封功能。环绕设置的密封段31能够将第一套段21与轴承座10之间的间隙的一侧封堵，从而防止气体通过间隙而造成漏风。
如图2和图3所示，密封结构30还包括引导段32，引导段32环绕设置在第二套段22的外表面，并且引导段32位于第一套段21和密封段31之间，引导段32的横截面的直径沿第一套段21至第二套段22的方向逐渐增大。如此设置，在将轴承套20的密封段31装入轴承座10时，能够通过引导段32的导向作用实现快速装配，避免了因密封段31的端面与轴承座10的端面抵接而妨碍安装的问题。
在本实施例中，密封段31的横截面的直径大于或等于轴承座10的内表面的直径。这样在将轴承套20装配到轴承座10中后，密封段31能够起到良好的密封作用。为了提高密封效果，可以将密封段31的横截面的直径设置为大于轴承座10的内表面的直径，即密封段31与轴承座10过盈配合。密封段31与轴承座10之间的过盈量应根据材料和加工工艺设置为合适的值，以防止因过盈量太大而不利于拆装。
其中，引导段32和密封段31可以设置为一体式结构，这样既能够提高结构强度又便于密封结构30的制造。密封结构30与第二套段22可以作为两个独立的部件分别加工，也可以设置为一体式结构整体加工。为了提高结构强度并便于加工，本实施例中将密封结构30与第二套段22设置为一体式结构。
如图1所示，轴承套20还包括筋条23，筋条23沿第一套段21的轴线方向设置在第一套段21的外表面上，并且筋条23为多个，多个筋条23沿第一套段21的圆周方向间隔设置。间隙设置在第一套段21的外表面位于相邻两个筋条23之间的部分与轴承座10的内表面之间。这样，通过间隙的作用可以方便地将轴承套20插入到轴承座10中，同时，将轴承套20插入到轴承座10后，多个筋条23与轴承座10的内表面接触，从而对轴承套20起到了支撑作用。因此，此种设置方式既便于轴承组件的装配又能够提高轴承组件的结构强度。
为了降低轴承组件的重量并降低制造成本，可以将轴承座10的材质设置为橡胶或塑料，也可以将轴承套20的材质设置为橡胶或塑料。如此设置，不但能降低轴承组件的重量和制造成本，而且由于橡胶或塑料有一定的弹性，还能够便于轴承组件的装配。同时，使用橡胶或塑料制造轴承座10与轴承套20，可以增大轴承座10与密封结构30之间的过盈量。如此设置一方面不会造成装配上的困难，另一方面能够增大轴承座10与密封结构30相互作用的挤压力，从而提高密封效果。
可选地，轴承套20与密封结构30为一体式结构，这样能够提高部件的结构强度。当轴承套20与密封结构30的材质为橡胶或塑料时，可以使用注塑工艺进行制造，这样既能够减少原材料的用量，又能够提高生产效率。
如图2所示，轴承座10与轴承套20之间具有卡接结构。如此设置，轴承座10与轴承套20装配好后，可以通过卡接结构的作用实现轴承座10与轴承套20的可靠连接，从而加强连接强度，防止轴承座10与轴承套20分离。
具体地，卡接结构包括凸起41和凹槽42，其中，凸起41设置在轴承座10的内侧，凹槽42设置在第一套段21的外侧，凸起41与凹槽42配合连接。这样，轴承座10与轴承套20装配好后，凸起41插入到凹槽42中实现卡接功能。如此设置能够以简单的结构实现轴承座10与轴承套20的可靠连接。为了进一步提高连接强度，可以在轴承座10的内侧沿圆周方向间隔设置多个凸起41。相应地，在第一套段21的外侧沿圆周方向间隔设置多个凹槽42，多个凸起41与多个凹槽42配合连接，共同起到卡接作用。
进一步地，轴承套20具有腔体，腔体位于第一套段21内或第二套段22内，腔体还可以位于第一套段21和第二套段22内。轴承组件还包括轴承50，轴承50设置在腔体内，轴承50用于支承空调器的送风装置。送风装置用于由空调器的内部向空调器的外部送风，以调节室内环境的温度。轴承50可以与送风装置连接，以对送风装置起支撑和固定的作用，并使送风装置顺利转动。
如图4所示，本发明的另一实施例提供了一种空调器，空调器包括底壳200、送风装置300和轴承组件，送风装置300通过轴承组件可转动地设置在底壳200上，其中，轴承组件为上述提供的轴承组件。应用本实施例提供的空调器，由于轴承套20的第一套段21与轴承座10之间具有间隙，因此可以方便地将第一套段21插入到轴承座10中。在第一套段21的引导下第二套段22也可以方便地插入到轴承座10中，从而将轴承套20装配到轴承座10上。由于轴承组件还具有密封结构30，当轴承套20装配到轴承座10上之后，密封结构30能够将轴承套20两侧的空间隔离，这样气体就不能通过第一套段21与轴承座10之间的间隙而造成漏风。因此本实施例的技术方案能够避免因为漏风而在空调器的风道内产生水珠的问题，防止水珠对空调器内的零部件造成损害，从而提高了空调器的可靠性，延长了空调器的使用寿命。
具体地，轴承组件的轴承座10与底壳200固定连接。送风装置300包括两个连接板301、多个叶片302和转轴303。其中，多个叶片302间隔设置在两个连接板301之间，优选地，多个叶片环绕在转轴303的外侧。转轴303与两个连接板301中的至少一个连接，转轴303的 一端与轴承组件的轴承50配合连接。转轴303转动可以带动多个叶片302转动，从而由空调器的内部向空调器的外部送风。轴承组件中的轴承50对转轴303起支撑和固定作用。轴承50可以活动地设置在轴承套20内，这样轴承50可以随转轴303一起转动；轴承50还可以固定设置在轴承套20内，这样转轴303相对轴承50转动。轴承50或转轴303应该采用耐磨材料，以延长装置的使用寿命。
进一步地，轴承组件的密封结构30设置在轴承组件的轴承套20靠近送风装置300的一端。如此设置可便于从靠近送风装置300的位置将轴承套20装入轴承座10中。
应用本发明的技术方案，由于轴承套20的第一套段21与轴承座10之间具有间隙，因此可以方便地将第一套段21和第二套段22插入到轴承座10中。由于轴承组件还具有密封结构30，当轴承套20装配到轴承座10上之后，密封结构30能够将轴承套20两侧的空间隔离，防止气体通过间隙而造成漏风。将密封结构30设置为环绕在第二套段22外表面的密封段31和引导段32，既能够起到良好的密封效果又不会造成安装上的困难。将密封结构30与第二套段22设置为一体式结构，能够提高结构强度并便于加工。本发明的技术方案能够解决现有技术中的轴承组件漏风的问题，这样可以避免在空调器内产生的水珠对零部件造成损害，从而提高了空调器的可靠性，延长了空调器的使用寿命。
