具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考图1-图10描述根据本发明实施例的定子100，定子100可装配在电机上。
如图1-图3所示，根据本发明实施例的定子100可以包括：定子铁芯1、绝缘筒体2、安装点3、定子绕组4和多个防撞凸块5。其中，安装点3适于安装座簧，从而当定子100装配在电机且电机装配在压缩机上时，便于压缩机的机芯通过座簧200与压缩机的壳体相连。
具体地，如图1-图3所示，绝缘筒体2和安装点3设在定子铁芯1的轴向一端的端面上。如图10所示，绝缘筒体2包括放置部21和安装部22，放置部21设在安装部22上，多个安装点3位于放置部21外侧，也就是说，绝缘筒体2和安装点3设在定子铁芯1的轴向一端的端面上，且多个安装点3环绕在绝缘筒体2的外侧。可选地，多个安装点3在绝缘筒体2的周向上均匀间隔开地环绕绝缘筒体2设置。例如，如图1-图3所示，安装点3为四个，即第一安装点3a至第四安装点3d，四个安装点3在绝缘筒体2的周向上均匀间隔开地环绕绝缘筒体2设置。
定子铁芯1的横截面为环形形状，定子铁芯1的内周壁上形成多个间隔设置的定子齿，定子绕组4缠绕在定子铁芯1的定子齿上，定子绕组4的多根绕线41通过设置在放置部21上的过线孔213缠绕在放置部21的外周壁上，如图5和图10所示。
这里，可以理解的是，定子绕组4的绕线41的个数与电机的相数有关，例如如图4-图6所示，电机为三相电机时，定子绕组4的绕线41的个数为三根即第一绕线41a、第二绕线41b和第三绕线41c。
多个防撞凸块5间隔开地设在放置部21的外周壁上，例如如图1-图3所示，三个防撞凸块5(即第一防撞凸块5a至第三防撞凸块5c)间隔开地设在放置部21的外周壁上。
每根绕线41对应设置至少一个在径向上与安装点3正对设置的防撞凸块5，例如，上述的第一绕线41a对应设置一个在径向上与安装点3正对设置的防撞凸块5，第二绕 线41b对应设置两个在径向上与安装点3正对设置的防撞凸块5，第三绕线41c对应设置两个在径向上与安装点3正对设置的防撞凸块5。
防撞凸块5的外周壁延伸超出绕线41，由此，当定子100用在电机上且电机装配在压缩机上时，在压缩机晃动的情况下，防撞凸块5的设置可保证座簧和绕线41不直接接触，从而避免了绕线41的破损，保证了压缩机的的安全性和可靠性。
根据本发明实施例的定子100，通过在放置部21的外周壁上间隔设置多个防撞凸块5，同时使得防撞凸块5的外周壁延伸超出绕线41，这样，当定子100用在电机上且电机装配在压缩机上时，即便压缩机产生晃动，防撞凸块5也能保证座簧和绕线41不直接接触，从而避免了绕线41的破损，保证了压缩机的的安全性和可靠性。
在本发明的一些实施例中，如图4-图9所示，放置部21的外周壁上设有多个放置凸块211，每个防撞凸块5的下方设置至少一个放置凸块211以限定出相应的绕线41的过线槽212。例如，如图4和图7所示，第一防撞凸块5a的下方的放置凸块211与第一防撞凸块5a之间限定出用于第一绕线41a通过的过线槽212；如图5和图8所示，第二防撞凸块5b的下方的放置凸块211与第二防撞凸块5b之间限定出用于第二绕线41b通过的过线槽212；如图6和图9所示，第三防撞凸块5c的下方的放置凸块211与第三防撞凸块5c之间限定出用于第三绕线41c通过的过线槽212。从而，在定子绕组4的绕线41缠绕在放置部21的外周壁上时可穿过过线槽212以便于过线槽212对绕线41的固定和限位，避免绕线41的移位。
具体地，如图7-图9所示，放置凸块211与相应的防撞凸块5在轴向上交错设置。由此，结构简单。
可选地，如图7-图9所示，过线槽212的在轴向上的高度L1的取值范围为1.5mm～2mm。由此，一方面可在压缩机产生晃动的过程中防止座簧200卡入过线槽212内而对绕线41造成损坏，另一方面还可以便于绕线41顺利装配入过线槽212内且使得绕线41具有足够的拉紧力。可选地，L1为1.8mm。
在本发明的一些实施例中，位于最上方的绕线41对应的防撞凸块5的顶端延伸超出放置部21的顶端面。例如，如图4和图7所示，第一绕线41a为最上方的绕线41，第一绕线41a对应的第一防撞凸块5a的顶端延伸超出放置部21的顶端面。这样，可确保防撞凸块5在起阻隔相应的座簧200和绕线41接触作用的同时，还可避免因座簧200的撞击而导致绝缘筒体2壁的破裂。
具体地，如图7所示，防撞凸块5的顶端面和放置部21的顶端面之间的距离H的取值范围为1.4mm～1.6mm。例如，H为1.47、1.56mm。
在本发明的一些实施例中，除去位于最上方的绕线41的其余绕线41对应的防撞凸块5的顶端面与放置部21的顶端面平齐。例如，如图5-图6以及图8-图9所示，第一绕线41a为最上方的绕线41，第二绕线41b和第三绕线41c位于第一绕线41a的下方，第二绕线41b对应的第二防撞凸块5b和第三绕线41c对应的第三防撞凸块5c的顶端面均与放置部21的顶端面平齐。由此，结构简单。
可选地，多个防撞凸块5的外周壁位于同一个圆上。由此，不但结构简单，而且有利于优化定子100的结构。
在本发明的一些实施例中，以每个安装点3为圆心且半径R为15mm的圆为相应安装点3的轨迹圆，与每个安装点3正对设置的防撞凸块5在定子铁芯1的轴向上的正投影位于相应安装点3的轨迹圆内。例如，如图3所示，以第一安装点3a为圆心且半径R为15mm的圆为第一安装点3a的轨迹圆，与第一安装点3a正对设置的第一防撞凸块5a在定子铁芯1的轴向上的正投影位于第一安装点3a的轨迹圆内,以第二安装点3b为圆心且半径R为15mm的圆为第二安装点3b的轨迹圆，与第二安装点3b正对设置的第二防撞凸块5b在定子铁芯1的轴向上的正投影位于第二安装点3b的轨迹圆内,以第三安装点3c为圆心且半径R为15mm的圆为第三安装点3c的轨迹圆，与第三安装点3c正对设置的第三防撞凸块5c在定子铁芯1的轴向上的正投影位于第三安装点3c的轨迹圆内。由此，有利于优化安装点3与防撞凸块5之间的距离，从而优化定子100的结构。
下面参考图1-图10对本发明一个具体实施例的定子100的结构进行详细说明。
如图1-图3所示，本发明实施例的定子100包括：定子铁芯1、绝缘筒体2、四个安装点3(即第一安装点3a至第四安装点3d)、三个防撞凸块5(即第一防撞凸块5a、第二防撞凸块5b和第三防撞凸块5c)和定子绕组4。其中，安装点3适于安装座簧200，从而当定子100装配在电机且电机用在压缩机上时，便于压缩机的机芯通过座簧200与压缩机的壳体相连。
定子铁芯1的横截面为环形形状，定子铁芯1的内周壁上形成多个间隔设置的定子齿，定子绕组4缠绕在定子铁芯1的定子齿上。
具体地，绝缘筒体2和安装点3设在定子铁芯1的轴向一端的端面上。如图10所示，绝缘筒体2包括放置部21和安装部22，放置部21设在安装部22上，四个安装点3位于放置部21外侧且四个安装点3在绝缘筒体2的周向上均匀间隔开地环绕在放置部21设置。定子绕组4的三根绕线41(即第一绕线41a、第二绕线41b和第三绕线41c)通过设置在放置部21上的过线孔213缠绕在放置部21的外周壁上。
三个防撞凸块5间隔开地设在放置部21的外周壁上。第一绕线41a与第一防撞凸 块5a对应设置，且第一防撞凸块5a在径向上与第一安装点3a正对设置，第二绕线41b分别与第一防撞凸块5a和第二防撞凸块5b对应设置，且第二防撞凸块5b与第二安装点3b正对设置，第三绕线41c分别与第二防撞凸块5b和第三防撞凸块5c对应设置，且第三防撞凸块5c与第三安装点3c正对设置，每个防撞凸块5的外周壁延伸超出导线。由此，第一防撞凸块5a可将第一绕线41a和第二绕线41b与安装在第一安装点3a上的座簧200阻隔，第二防撞凸块5b可将第二绕线41b和第三绕线41c与安装在第二安装点3b上的座簧200阻隔，第三防撞凸块5c可将第三绕线41c与安装在第三安装点3c上的座簧200阻隔。由此，在压缩机机芯晃动的情况下，防撞凸块5的设置可保证座簧和绕线41不直接接触，从而避免了绕线41的破损，保证压缩机的的安全性和可靠性。
以每个安装点3为圆心且半径R为15mm的圆为安装点3的轨迹圆。具体而言，以第一安装点3a为圆心且半径R为15mm的圆为第一安装点3a的轨迹圆，与第一安装点3a正对设置的第一防撞凸块5a在定子铁芯1的轴向上的正投影位于第一安装点3a的轨迹圆内,以第二安装点3b为圆心且半径R为15mm的圆为第二安装点3b的轨迹圆，与第二安装点3b正对设置的第二防撞凸块5b在定子铁芯1的轴向上的正投影位于第二安装点3b的轨迹圆内,以第三安装点3c为圆心且半径R为15mm的圆为第三安装点3c的轨迹圆，与第三安装点3c正对设置的第三防撞凸块5c在定子铁芯1的轴向上的正投影位于第三安装点3c的轨迹圆内。
放置部21的外周壁上设有多个放置凸块211，每个防撞凸块5的下方设置一个放置凸块211以限定出相应的绕线41的过线槽212。具体地，如图4-图6所示，第一防撞凸块5a与位于其下方的放置凸块211限定出第一绕线41a的过线槽212且第一防撞凸块5a与相应的放置凸块211在轴向上交错设置，第二防撞凸块5b与位于其下方的放置凸块211限定出第二绕线41b的过线槽212且第二防撞凸块5b与相应的放置凸块211在轴向上交错设置，第三防撞凸块5c与位于其下方的放置凸块211限定出第三绕线41c的过线槽212且第三防撞凸块5c与相应的放置凸块211在轴向上交错设置。
如图7-图9所示，过线槽212在轴向上的高度L1的取值范围为1.5mm～2mm。由此，一方面可在压缩机产生晃动的过程中防止座簧卡入过线槽212内而对绕线41造成损坏，另一方面还可以便于绕线41顺利装配入过线槽212内且使得绕线41具有足够的拉紧力。如图4-图7所示，在三根绕线41缠绕在放置部21的外周壁上时，三个绕线41不位于同一水平高度。位于最上方的第一绕线41a对应的第一防撞凸块5a的顶端延伸超出放置部21的顶端面。这样，可确保第一防撞凸块5a在起阻隔相应的座簧200和第一绕线41a接触作用的同时，还可避免因座簧200的撞击而导致绝缘筒体2壁的破裂。
具体地，第一防撞凸块5a的顶端面和放置部21的顶端面之间的距离H的取值范围为1.4mm～1.6mm。除去位于最上方的第一绕线41a外，第二绕线41b对应的第二防撞凸块5b和第三绕线41c对应的第三防撞凸块5c的顶端面均与放置部21的顶端面平齐。
多个防撞凸块5的外周壁位于同一个圆上。由此，不但结构简单，而且有利于优化定子100的结构。
