具体实施方式
首先，本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合。例如，虽然本发明实施例的空气净化装置是结合立式空调进行描述的，但该空气净化装置并不局限于应用在立式空调中，其他具有水洗空气使用需求的设备均可配置本发明实施例的空气净化装置。
其次，需要说明的是，在本发明的描述中，术语“内”、“外”等指示的方向或位置关系的术语是基于附图所示的方向或位置关系，这仅仅是为了便于描述，而不是指示或暗示所述装置或构件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个构件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
本文中所述的“上”“下”“顶”“底”等方位词指的是立式空调 处于正常工作状态时的方位。前述方位词仅用于方便描述，并不构成对结构的任何限定。本文中所述的“前”“后”“左”“右”是当用户面对立式空调时的方位，靠近用户一侧为“前”，背离用户一侧为“后”，靠近用户左手边一侧为“左”，靠近用户右手边一侧位“右”。
立式空调在轴向上的尺寸较大，在装配时通常是将其平放，并在端部进行装配操作。进风口通常设置于立式空调的后部或者靠近后部的两侧，出风口通常设置于立式空调的前部。具有两个或者多个风机的立式空调中，为了保证各个风机均能够实现后进风前出风，需要将各个风机分左右两侧布置，且左右两侧的风机的转动方向不同。在进行装配时，由于各个风机的贯流风轮是在平放状态下与电机连接，且有些装配过程设置为首先将风机的贯流风轮安装于风道结构内部，再安装电机，非常不便于观察，各个电机外形上又是相同的，因此极容易发生装错的问题。例如将左风轮与右电机连接，而右风轮与左电机连接，这样会使得风路与期望的风路正好相反，即出风口变为进风口。一旦装错，只有到测试阶段才会发现问题，再返回到装配工序装配，严重影响生产效率。
在相关技术中，为方便安装及简化结构，贯流风轮从风道结构的侧部装入，这样电机可直接安装于风道结构上，结构比较简单，但为了贯流风轮的装入，需要在风道结构的两端部之间预留出安装空间，在贯流风轮装入风道结构之后，贯流风轮与风道结构的上端部之间会存在比较大的间隔，电机需要较长的电机轴才能与贯流风轮连接，若在电机轴上再设置防错装结构，势必会使得电机轴的结构强度大打折扣，影响电机与贯流风轮的连接可靠性。
针对上述问题，本发明实施例提供了一种立式空调，通过改变各个贯流风轮的安装方式减小需要的电机轴长度，在此基础上，在支撑电机的下支撑座与相应电机之间以及相应贯流风轮之间设置防错装结构来实现防呆，从根本上解决错装问题，提高装配效率，且无需改变电机轴结构，保证电机与贯流风轮之间的连接可靠性。
下面参考附图描述本发明实施例的立式空调。
参阅图1至图3，图1和图2为本发明实施例的立式空调中风道结构、第一风机、第二风机的配合结构立体图及局部放大图。图3为本发明实施例的立式空调的横剖视图。如图1至图3所示，本发明实施例提供的立式空调包括外壳10和设置于外壳10内的风道结构20、第一风机 30和第二风机40。图14是本发明实施例的立式空调中风道结构的立体图，如图14所示，风道结构20包括上端部21和下端部22，上端部21例如可以用于安装扫风叶片及其传动机构等，下端部22例如可以用于安装换热器50、叶轮等。风道结构20还包括连接上端部21和下端部22的连接立柱23，连接立柱23例如可以构成立式空调的第一风机30、第二风机40的蜗壳和蜗舌。上端部21上设置有供各个风机的贯流风轮装入风道结构的第一装入口211和第二装入口214。
第一风机30和第二风机40用于实现立式空调的送风，具体地，外壳10上设置进风口(图中未示出)和出风口11，第一风机30和第二风机40将外部空气经进风口送入立式空调内，与换热器50换热，并将换热后的空气经出风口11送出立式空调。进风口可以设置一个，也可以设置多个，出风口11可以设置一个，也可以设置多个，进风口设置在第一风机30和第二风机40的风路上游侧，出风口11设置在第一风机30和第二风机40的风路下游侧。在图3所示的实施例中，第一风机30和第二风机40呈左右并排设置，进风口设置在立式空调的后部，换热器50设置于进风口与第一风机30、第二风机40之间，第一风机30和第二风机40共用进风口和换热器50，出风口11设置有两个，呈左右布置，左侧出风口用于第一风机30出风，右侧出风口用于第二风机40出风，具体风路如图3中带箭头的曲线所示。
图4为本发明实施例的立式空调中省去第一上压盖的第一风机的主视图，如图2和图4所示，第一风机30包括第一贯流风轮31和第一电机32，第一电机32用于驱动第一贯流风轮31转动以形成第一风机30的风路。第一贯流风轮31经第一装入口211装入风道结构20中，即装入至风道结构20的上端部21与下端部22之间。为了实现第一电机32的安装，第一风机30还包括第一下支撑座33，第一下支撑座33固定于第一装入口211处，第一电机32的第一电机主体322支撑于第一下支撑座33，第一电机32的第一电机轴321穿过第一下支撑座33和第一装入口211，并与第一贯流风轮31的顶部固定连接。第一贯流风轮31的底部可转动地支撑于下端部22，即，第一贯流风轮31支撑于下端部22，且其能够相对下端部22转动，例如，下端部22上设置有第一转动轴承，如图4所示，第一贯流风轮31的底部向下延伸形成有第一转轴315，第一转轴315与第一转动轴承配合。
图7是本发明实施例的立式空调中省去第二上压盖的第二风机的主视图，如图2和图7所示，第二风机40包括第二贯流风轮41和第二电机42，第二电机42用于驱动第二贯流风轮41转动以形成第二风机40的风路。第二贯流风轮41经第二装入口214装入风道结构20中，即装入至风道结构20的上端部21与下端部22之间。为了实现第二电机42的安装，第二风机40还包括第二下支撑座43，第二下支撑座43固定于第二装入口214处，第二电机42的第二电机主体422支撑于第二下支撑座43，第二电机42的第二电机轴421穿过第二下支撑座43和第二装入口214，并与第二贯流风轮41的顶部固定连接。第二贯流风轮41的底部可转动地支撑于下端部22，例如，下端部22上设置有第二转动轴承，如图7所示，第二贯流风轮41的底部向下延伸形成有第二转轴415，第二转轴415与第二转动轴承配合。
第一电机轴321和第二电机轴421的转动方向不同，以使得第一贯流风轮31和第二贯流风轮41的转动方向相反，从而满足两个风机均实现大致的后进风前出风的风路。第一下支撑座33与第一贯流风轮31之间设置有第一防错装结构，第一下支撑座33与第一电机主体322的之间设置有第二防错装结构，第二下支撑座43与第二贯流风轮41之间设置有第三防错装结构，第二下支撑座43与第二电机主体422之间设置有第四防错装结构。
本发明实施例提供的立式空调中，在风道结构20的上端部21设置第一装入口211和第二装入口214，第一贯流风轮31和第二贯流风轮41分别由第一装入口211和第二装入口214装入风道结构20中，无需在风道结构20的上端部21和下端部22之间预留安装空间，缩减了贯流风轮与对应电机之间(即第一贯流风轮31与第一电机32之间以及第二贯流风轮41与第二电机42之间)的距离，从而保证电机与贯流风轮的连接可靠性。进一步地，在第一装入口211和第二装入口214处分别设置用于支撑第一电机主体322、第二电机主体422的第一下支撑座33和第二下支撑座43，在第一下支撑座33与第一贯流风轮31之间、第一下支撑座33与第一电机主体322之间、第二下支撑座43与第二贯流风轮41之间、第二下支撑座43与第二电机主体422之间设置防错装结构，如此，生产人员在装反的情况下无法顺利装配，从结构上实现防呆，保证电机和贯流风轮之间不会发生错装，进而保证立式空调的生产效率， 另外，无需改动第一电机32和第二电机42的电机轴结构即可实现防错装，进一步保证电机与贯流风轮的连接可靠性。
为了保证电机轴与贯流风轮之间的连接可靠性，优选地，如图4所示，第一贯流风轮31包括第一上端盖311、第一下端盖312以及设置于第一上端盖311和第一下端盖312之间的第一贯流叶片313，第一上端盖311包括第一上端盖本体3111以及由第一上端盖本体3111的中部延伸形成的第一连接套筒3112，第一电机轴321与第一连接套筒3112配合连接。
第一连接套筒3112可以设置在第一上端盖本体3111的上部，也可以设置在第一上端盖本体3111的下部，为了保证结构的紧凑性，在一个优选的实施例中，第一连接套筒3112由第一上端盖本体3111的中部向下延伸形成，第一电机轴321伸入至第一贯流风轮31内部与第一连接套筒3112配合。
为了实现第一电机轴321与第一连接套筒3112之间的轴向定位，第一电机轴321上设置有第一限位槽，第一连接套筒3112的侧壁上螺纹连接有第一螺纹连接件314，第一螺纹连接件314的端部与第一限位槽3222配合以对第一电机轴321与第一连接套筒3112进行轴向定位，防止第一电机轴321在带动第一连接套筒3112转动时发生轴向错位。
类似地，如图7所示，第二贯流风轮41包括第二上端盖411、第二下端盖412以及设置于第二上端盖411和第二下端盖412之间的第二贯流叶片413，第二上端盖411包括第二上端盖本体4111以及由第二上端盖本体4111的中部延伸形成的第二连接套筒4112，第二电机轴421与第二连接套筒4112配合连接。第二连接套筒4112可以设置在第二上端盖本体4111的上部，也可以设置在第二上端盖本体4111的下部，为了保证结构的紧凑性，在一个优选的实施例中，第二连接套筒4112由第二上端盖本体4111的中部向下延伸形成，第二电机轴421伸入至第二贯流风轮41内部与第二连接套筒4112配合。
为了实现第二电机轴421与第二连接套筒4112之间的轴向定位，第二电机轴421上设置有第二限位槽，第二连接套筒4112的侧壁上螺纹连接有第二螺纹连接件414，第二螺纹连接件414的端部与第二限位槽4223配合以对第二电机轴421与第二连接套筒4112进行轴向定位，防止第二电机轴421在带动第二连接套筒4112转动时发生轴向错位。
第一防错装结构和第三防错装结构可以为任意能够使得第一下支撑座33与第二贯流风轮41之间、第二下支撑座43与第一贯流风轮31之间无法装配或者装配后会发生运动干涉的结构，例如，第一下支撑座33的下方设置第一环形结构，第一贯流风轮31的上方设置有第二环形结构，第二下支撑座43的下方设置第三环形结构，第二贯流风轮41的上方设置有第四环形结构，第一环形结构与第二环形结构的尺寸不同，第三环形结构和第四环形结构的尺寸不同，第一环形结构与第四环形结构的尺寸相同，第二环形结构与第三环形结构的尺寸相同，从而当发生错装时，第一环形结构会与第四环形结构抵靠而使得第一下支撑座33上的第一电机32无法与第二贯流风轮41顺利装配，以及第二环形结构与第四环形结构抵靠而使得第二下支撑座43上的第二电机42无法与第一贯流风轮31顺利装配。
为了便于加工，在一个优选的实施例中，图5是本发明实施例的立式空调中第一下支撑座的仰视图，图6是本发明实施例的立式空调中第一上端盖的俯视图，如图5和图6所示，第一防错装结构包括由第一下支撑座33向下延伸形成的第一凸起结构333和由第一贯流风轮31的顶部向上延伸形成的第二凸起结构3113，例如，在图6所示的实施例中，第二凸起结构3113设置于第一上端盖本体3111的顶部。第一凸起结构333和第二凸起结构3113在径向上相互错开设且在轴向上有部分结构交叠。
其中，第一凸起结构333与第二凸起结构3113在径向上相互错开设置指的是，参考图5和图6，第一凸起结构333完全位于第二凸起结构3113的径向外侧，即第一凸起结构333的径向内端点与第一下支撑座33的中心之间的径向距离大于第二凸起结构3113的径向外端点与第一下支撑座33的中心之间的径向距离。或者，第一凸起结构333完全位于第二凸起结构3113的径向内侧，即第一凸起结构333的径向外端点与第一下支撑座33的中心之间的径向距离小于第二凸起结构3113的径向内端点与第一下支撑座33的中心之间的径向距离。
参考图4，第一凸起结构333和第二凸起结构3113在轴向上有部分结构交叠指的是，第一下支撑座33的下表面与第一贯流风轮31的上表面之间的轴向距离小于第一凸起结构333和第二凸起结构3113的轴向距离之和。
图8是本发明实施例的立式空调中第二下支撑座的仰视图，图9是本发明实施例的立式空调中第二上端盖的俯视图。如图8和图9所示，第三防错装结构包括由第二下支撑座43向下延伸形成的第三凸起结构433和由第二贯流风轮41的顶部向上延伸形成的第四凸起结构4113。第三凸起结构433和第四凸起结构4113在径向上相互错开设且在轴向上有部分结构交叠。
其中，第三凸起结构433与第四凸起结构4113在径向上相互错开设置指的是，如图8和图9所示，第三凸起结构433完全位于第四凸起结构4113的径向外侧，即第三凸起结构433的径向内端点与第二下支撑座43的中心之间的径向距离大于第四凸起结构4113的径向外端点与第二下支撑座43的中心之间的径向距离。或者，第三凸起结构433完全位于第四凸起结构4113的径向内侧，即第三凸起结构433的径向外端点与第二下支撑座43的中心之间的径向距离小于第四凸起结构4113的径向内端点与第二下支撑座43的中心之间的径向距离。
如图7所示，第三凸起结构433和第四凸起结构4113在轴向上有部分结构交叠指的是，第二下支撑座43的下表面与第二贯流风轮41的上表面之间的轴向距离小于第三凸起结构433和第四凸起结构4113的轴向距离之和。
由于第一凸起结构333和第二凸起结构3113在径向上错开，因此两者即使轴向上有交叠也不会影响第一贯流风轮31相对第一下支撑座33转动。同样地，由于第三凸起结构433和第四凸起结构4113在径向上错开，因此两者即使轴向上有交叠也不会影响第二贯流风轮41相对第二下支撑座43转动。
第一凸起结构333与第一下支撑座33的中心之间的径向距离范围为第一尺寸范围，第二凸起结构3113与第一贯流风轮31的中心之间的径向距离范围为第二尺寸范围，第三凸起结构433与第二下支撑座43的中心之间的径向距离范围为第三尺寸范围，第四凸起结构4113与第二贯流风轮41的中心之间的径向距离范围为第四尺寸范围，第一尺寸范围与第四尺寸范围至少部分重叠，第二尺寸范围与第三尺寸范围至少部分重叠。又由于第一凸起结构333和第二凸起结构3113之间、第三凸起结构433和第四凸起结构4113之间在轴向上均有交叠，使得第一电机32与第二贯流风轮41无法顺利装配或者装配后第二贯流风轮41 无法自由转动即发生运动干涉，以及使得第二电机42与第一贯流风轮31无法顺利装配或者装配后第一贯流风轮31无法自由转动即发生运动干涉，从而达到结构上的防呆。
第一凸起结构333、第二凸起结构3113、第三凸起结构433、第四凸起结构4113可以为任意能够满足上述要求的结构，例如，均设置为沿周向均匀布置的扇环形结构。为了进一步简化结构，保证装配过程不会对立式空调的质量造成影响，在一个优选的实施例中，如图5所示，在与第一贯流风轮31的轴线垂直的平面内，第一凸起结构333呈沿径向延伸的长形结构。如图6所示，第二凸起结构3113呈沿与径向垂直的方向延伸的长形结构。如图8所示，在与第二贯流风轮41的轴线垂直的平面内，第三凸起结构433呈沿径向延伸的长形结构。如图9所示，第四凸起结构4113呈沿与径向垂直的方向延伸的长形结构。
上述结构设置使得第一下支撑座33上的第一电机32错装入第二贯流风轮31时，在进行运动干涉测试即转动第二贯流风轮31时，第四凸起结构4113的端面会撞击到第一凸起结构333的较大的侧面上，从而保证干涉测试不会影响第一下支撑座33和第二贯流风轮41的质量。类似地，若第二下支撑座43上的第二电机42错装入第一贯流风轮31时，在进行运动干涉测试即转动第一贯流风轮31时，第二凸起结构3113的端面会撞击到第三凸起结构433的较大的侧面上，从而保证干涉测试不会影响第二下支撑座43和第一贯流风轮31的质量。
第二防错装结构和第四防错装结构可以设置为任意能够使得第一下支撑座33与第一电机主体322之间、第二下支撑座43与第二电机主体422之间无法正常装配的结构。例如也可以设置为与前述的第一防错装结构、第三防错装结构类似的第一至第四环形结构。
由于第一电机32运行时其第一电机轴321会一直带动第一贯流风轮31运动，为了缓冲第一电机32的震动，避免整机发生异响，进一步优选地，如图10所示，第一下支撑座33包括第一支撑座本体331和设置于第一支撑座本体331上的第一缓冲件332，即第一缓冲件332设置于第一支撑座本体331与第一电机32之间。利用第一缓冲件332来缓冲第一电机32的振动，避免第一电机32的振动传递至风道结构20，一方面能够降低立式空调的噪音，另一方面也能够进一步提高立式空调的结构可靠性。
类似地，为了缓冲第二电机42的震动，如图12所示，第二下支撑座43包括第二支撑座本体431和设置于第二支撑座本体431上的第二缓冲件432，即第二缓冲件432设置于第二支撑座本体431与第二电机42之间。利用第二缓冲件432来缓冲第二电机42的振动，避免第二电机42的振动传递至风道结构20。
第一缓冲件332包括呈环形的第一缓冲部3321，第一电机主体322的部分结构位于所述第一缓冲部3321内，图11是本发明实施例的立式空调中第一电机的仰视图，如图10和图11所示，第二防错装结构包括设置于第一缓冲部3321上的第一限位槽3323，以及设置于第一电机主体322上的第一限位凸起3221，第一限位槽3323与第一限位凸起3221相配合。

第一限位槽3323和第二限位槽4323的数量不同，例如，第一限位槽3323的数量为两个，第二限位槽4323的数量为三个，从而使得第一电机主体322无法装入第三缓冲部4321内，第二电机主体422无法装入第一缓冲部3321内。再例如，第一限位槽3323和第二限位槽4323的排布方式不同，例如，第一限位槽3323沿周向均布设置多个，第二限位槽4323周向非均布设置，也能够防止错装。当然，也可以第一限位槽3323和第二限位槽4323的数量、排布方式均不同。
当然，可以理解的是，第一限位槽3323和第一限位凸起3221的位置可以互换，即第一限位槽设置于第一电机主体322上，第一限位凸起设置于第一缓冲部3321上。第二限位槽4323和第二限位凸起4221的位置也可以互换，即第二限位槽设置于第二电机主体422上，第二限位凸起设置于第三缓冲部4321上。
第一限位槽3323、第一限位凸起3221、第二限位槽4323、第二限位凸起4221可以为任意形状，在一个优选地实施例中，为了方便装配以及保证装配后的结构可靠性，如图10和图12所示，第一限位槽3323和第二限位槽4323为上下贯通第一缓冲部3321、第三缓冲部4321的条 形槽，相应地，如图11和图13所示，第一限位凸起3221和第二限位凸起4221为径向凸出于第一电机主体322、第二电机主体422设置的竖向延伸的长条形结构。
为了方便第一电机32与第一下支撑座33的装配，进一步优选地，如图10所示，第一支撑座本体331上设置有第一凹槽3313，第一电机主体322的下部结构位于第一凹槽3313中，第一电机轴321由第一凹槽3313的槽底穿出第一支撑座本体331。第一缓冲件332容置于第一凹槽3313中，第一缓冲部3321的外侧壁与第一凹槽3313的内侧壁贴合设置。
为了方便加工，第一支撑座本体331大致呈开口朝上的盖状结构，第一凹槽3313由盖状结构的底壁向上延伸形成，为了提高结构强度，第一凹槽3313的外侧壁与盖状结构的侧壁之间设置有多个第一加强筋条3315。
类似地，如图12所示，为了方便第二电机42与第二下支撑座43的装配，进一步优选地，如图12所示，第二支撑座本体431上设置有第二凹槽4313，第二电机主体422的下部结构位于第二凹槽4313中，第二电机轴421由第二凹槽4313的槽底穿出第二支撑座本体431。第二缓冲件432容置于第二凹槽4313中，第三缓冲部4321的外侧壁与第二凹槽4313的内侧壁贴合设置。
为了方便加工，第二支撑座本体431大致呈开口朝上的盖状结构，第二凹槽4313由盖状结构的底壁向上延伸形成，为了提高结构强度，第二凹槽4313的外侧壁与盖状结构的侧壁之间设置有多个第二加强筋条4315。
在一个实施例中，第一支撑座本体331与第一缓冲件332为分体结构，第二支撑座本体431与第二缓冲件432为分体结构。在该实施例中，如图10所示，第二防错装结构还包括设置于第一缓冲部3321的外侧壁上的第三限位凸起3324，以及设置于第一凹槽3313的内侧壁上的第三限位槽3314，第三限位凸起3324与第三限位槽3314相配合。如图12所示，第四防错装结构还包括设置于第三缓冲部4321的外侧壁上的第四限位凸起4324，以及设置于第二凹槽4313的内侧壁上的第四限位槽4314，第四限位凸起4324与第四限位槽4314相配合。
为了提高结构强度，在一个优选实施例中，如图10所示，第三限 位槽3314设置在与第一加强筋条3315对应的位置，且进一步优选呈梯形槽。如图12所示，第四限位槽4314设置在与第二加强筋条4315对应的位置，且进一步优选呈梯形槽。
第三限位槽3314与第四限位槽4314的数量不同，例如，如图10和图12所示，第三限位槽3314的数量为两个，第四限位槽4314的数量为三个，从而使得第一缓冲部3321无法装入第二支撑座本体431，第二缓冲部3322无法装入第一支撑座本体331。再例如，第三限位槽3314与第四限位槽4314的排布方式不同，例如，第三限位槽3314沿周向均布设置，第四限位槽4314周向非均布设置，也能够防止错装。当然，也可以第三限位槽3314和第四限位槽4314的数量、排布方式均不相同。
当然，可以理解的是，第三限位槽3314和第三限位凸起3324的位置可以互换，即第三限位凸起设置在第一凹槽3313的内侧壁上，第三限位槽设置在第一缓冲部3321的外侧壁上。第四限位槽4314和第四限位凸起4324的位置也可以互换，即第四限位凸起设置在第二凹槽4313的内侧壁上，第四限位槽设置在第三缓冲部4321的外侧壁上。
进一步优选地，第一缓冲件332还包括与第一凹槽3313的底壁贴合设置的第二缓冲部3322，即第二缓冲部3322位于第一凹槽3313的底壁与第一电机主体322之间，为避免第二缓冲部3322影响第一电机轴321的转动，第二缓冲部3322上供第一电机轴321穿过的通孔直径大于第一电机轴321的外径。这样，通过第一缓冲件332能够全方位地将第一电机32与上端部21隔开，保证第一缓冲件332的缓冲效果。
类似地，第二缓冲件432还包括与第二凹槽4313的底壁贴合设置的第四缓冲部4322，即第四缓冲部4322位于第二凹槽4313的底壁与第二电机主体422之间，为避免第四缓冲部4322影响第二电机轴421的转动，第四缓冲部4322上供第二电机轴421穿过的通孔直径大于第二电机轴421的外径。这样，通过第二缓冲件432能够全方位地将第二电机42与上端部21隔开，保证第二缓冲件432的缓冲效果。
在另一实施例中，第一支撑座本体331与第一缓冲件332为一体加工成型件。第二支撑座本体431与第二缓冲件432为一体加工成型件。例如，第一支撑座本体331、第二支撑座本体431为塑料件，第一缓冲件332和第二缓冲件432为橡胶件，采用双色注塑方式将两种不同材料注塑为一体结构，这样，第一支撑座本体331与第一缓冲件332之间以 及第二支撑座本体431与第二缓冲件432之间无需再设置防错装结构。
为了实现第一下支撑座33与上端部21之间的可靠配合，进一步优选地，如图14所示，第一装入口211的边缘向上延伸形成有第一筒部212，第一筒部212的径向外侧沿其周向设置有多个第一安装柱213，如图2和图10所示，第一下支撑座33包括第一底盖3311以及设置于第一底盖3311外围的多个第一安装凸耳3312，第一底盖3311与第一筒部212插接配合，第一安装凸耳3312与第一安装柱213固定连接。第一安装柱213的数量不限，可以为两个、三个甚至更多，可根据具体的电机尺寸进行设置，例如，在图2所示的实施例中，第一安装柱213设置有三个，三个第一安装柱213沿第一筒部212的周向均匀布置，第一安装凸耳3312也对应设置三个，分别用于与相应的第一安装柱213固定连接。为了保证结构可靠性，第一安装柱213优选与第一筒部212的外侧面相连。
