结合图1至图3所示，根据本发明的实施例，提供了一种电机压板结构。
具体地，如图1所示，该电机压板结构包括压板本体10和压脚20。压脚20的第一端与压板本体10相连接并具有夹角地设置。压脚20的第二端用于与电机座相连接。
在本实施例中，将电机压板的压脚与压板本体设置成具有夹角的方式，这样设置能够有效地改变压脚在电机轴向上的装配深度，采用该结构的电机压板能够适用于不同厚度的电机安装，有效地提高了该电机压板的实用性。该电机压板的结构简单、使用方便。
其中，压板本体10为环形结构，压脚20的第一端与压板本体10的外边沿相连接。这样设置能够提高电机压板的稳定性和可靠性，减轻了电机压板的重量。
压板本体10的中部具有环形凸包11，环形凸包11内侧形成用于容纳电机后胶圈的容纳空间。
为了能够进一步地提高电机压板结构的可靠性，环形凸包11的上设置有环形限位筋12。
具体地，压脚20为多个，多个压脚20沿压板本体10的外边沿间隔地设置。这样设置能够有效地提高电机压板的安装稳定性。如图1所示，该压脚20为三个，三个压脚均匀地布置在压板本体10的外边沿上。
为了进一步地提高电机压板的强度，电机压板结构还设置了加强筋30。加强筋30为多个，多个加强筋30与多个压脚20一一对应地设置。其中，加强筋30设置于压脚20的第一端与压板本体10的连接处。
具体地，压脚20包括第一组成段21和第二组成段22。第一组成段21的第一端与压板本体10相连接并具有夹角的设置。第一组成段21的第二端沿朝向压板本体10的外侧逐渐远离压板本体10设置。第二组成段22的第一端与第一组成段21的第二端相连接并具有夹角地设 置，第二组成段22的第二端朝向压板本体10的外侧逐渐远离压板本体10设置，第二组成段22的第二端用于与压板本体10相连接。这样设置能够有效地提高电机压板的连接稳定性。
优选地，第一组成段21的第一端至第二端的宽度逐渐减小。第一组成段21成弧形结构。或为直线段结构。
上述实施例中的电机压板结构还可以用于空调器设备技术领域，即根据本发明的另一方面，提供了一种空调器，包括电机压板结构，电机压板结构为上述实施例的电机压板结构。
具体地，本申请提供了一种与电机座相配合的不同凸出高度的电机压板，用于安装不同厚度的电机，增加了电机座50的通用性，降低了生产制造的成本，提高了生产效率。
为了用户在使用过程中拆卸清洗壁挂式空调器室内机的方便，将该空调器设置成易拆卸式模块化空调器，电机座设计为可拆卸地安装在底座上，且电机座50一体注塑成型为一端完全开口的圆柱形电机腔，腔体另一端设置有电机前胶圈凹槽，用于承托电机和阻挡电机的轴向和径向运动，电机安装在电机腔内，再通过电机压板将电机两侧的橡胶圈压紧固定，电机40组装示意图如图2所示。目前一个电机座只能通过电机压板安装固定一种厚度的电机，设计制造壁挂式空调器时，根据空调器能效的不同需采用不同功率的电机，不同功率的电机直径相同而厚度不同，就需要专门设计不同的电机座，造成空调器制造成本的增加，物料的通用性降低，生产效率不高。
针对此问题，如图1所示，电机压板上设置有后胶圈限位筋和凸包，限位筋和凸包的中心和电机座前胶圈凹槽的中心重合，用于承托电机和阻挡电机的轴向和径向运动。电机压板需要通过三个螺钉60固定在电机座上，这样电机压板上形成三个固定压脚，在压脚的底部分别设置加强筋以增强电机压板强度和降低三个压脚的平面度。电机压板的凸起高度H(相当于第二组成段的凸起高度)根据电机厚度的大小确定，电机厚度越薄，凸起高度H越大，电机厚度适中时凸起高度H可以为零。电机座设计时按照较厚的电机进行设计，这样较易满足其他空调器结构件的装配要求，当电机厚度减薄时，电机压板凸起一定的高度H，以对电机进行很好的限位和固定。此种设计不管电机厚度大小如何，电机轴从电机座伸出位置相同，保证了电机最小轴长，尽可能地提高了电机效率。
通过设计不同凸起高度的电机压板，达到厚度不同电机的安装固定且固定可靠，这样更改体积较小、结构较简单且成本较低件实现了不同厚度电机安装的结构兼容，满足了空调器的能效要求，实现了体积较大、结构较复杂且成本较高件电机座的通用性，降低了生产制造的成本，提高了生产效率。
当电机座的设计按照较薄电机厚度进行且满足空调器其他结构件的装配要求，固定较薄电机的电机压板结构就变成了凸起高度H为零时的电机压板结构。当电机厚度较厚时，凸起高度H为负值，也即压脚的凸起方向与图1中的凸起方向相反(图中未示出)。
除上述以外，还需要说明的是在本说明书中所谈到的“一个实施例”、“另一个实施例”、“实施例”等，指的是结合该实施例描述的具体特征、结构或者特点包括在本申请概括性描 述的至少一个实施例中。在说明书中多个地方出现同种表述不是一定指的是同一个实施例。进一步来说，结合任一实施例描述一个具体特征、结构或者特点时，所要主张的是结合其他实施例来实现这种特征、结构或者特点也落在本发明的范围内。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
