背景技术
目前,电机包括定子和转子,转子以及定子构造成叠片铁芯,在定子槽中围绕每个单独的齿绕制有线圈。通常线圈缠绕在定子铁芯上,定子铁芯和线圈之间,有用于对线圈进行绝缘的绝缘骨架。

有鉴于此,本申请的第一方面提出了一种绝缘骨架,包括:第一支架;第二支架,与第一支架相对设置,第二支架上设有线槽,线槽贯穿第二支架的壁面,线槽的底壁的一部分向第二支架的底部倾斜形成倾斜部,倾斜部位于线槽朝向第一支架的一侧;第三支架,第三支架位于第一支架和第二支架之间并与第一支架和第二支架连接。

在具体应用中,绝缘骨架应用于定子中,定子包括定子铁芯、线圈和上述绝缘骨架,其中,绝缘骨架设置在定子铁芯的轴线方向的两端,线圈绕设在绝缘骨架和定子铁芯上。第一支架、第二支架和第三支架合围出绕线容纳部,用于容纳线圈,定子铁芯经过线槽进线,使得线圈沿着倾斜部向下倾斜,使得线圈绕设的更加紧密。
具体地,第一支架、第二支架和第三支架一体成型而成。
可以理解的是,线槽包括开口和与开口相对设置的底壁,线槽的底壁的一部分向第二支架的底部方向倾斜设置,以形成倾斜部,并且,倾斜部设置在线槽朝向第一支架的一侧,也即倾斜部设置在第一支架的内侧。也即,线槽的上半部分呈大致U形,开口位于U形的顶部,线槽的下半部分呈斜坡形,以使得过线时线圈更加紧凑,提升线圈绕设的固定性。
具体地,在将绝缘骨架应用到定子中时,第一支架靠近定子铁芯的内侧,第二支架靠近定子铁芯的外侧,第三支架连接于第一支架和第二支架并位于两者之间。
根据本申请提供的上述的绝缘骨架,还可以具有以下附加技术特征:
在上述技术方案中,进一步地,绝缘骨架还包括:端子容纳部,端子容纳部设于第二支架背离第一支架的一侧,用于容纳压接端子,沿第一方向,端子容纳部位于线槽的第一侧。

第二凸台设置在容纳槽靠近线槽的一侧,并且,第二凸台与第二支架的表面、以及容纳槽的外侧壁面合围出溢胶槽,其中,第二凸台的端部与容纳槽的壁面之间未完全闭合,具有缺口,从而便于线圈的线尾的切断和密封。
在具体应用中,第一凸台的底部设有走线槽,走线槽与槽口相对设置,使得线圈能够在走线槽内进一步固定,提升线圈的牢固性。
另外地,缺口的尺寸较小进而避免密封胶流出。具体地,缺口的宽度大于或等于1mm,且小于或等于5mm。

在该技术方案中,槽口包括相连通的第一通道和第二通道,也即槽口分为上半部分和下半部分,其中,第一通道位于上半部分,第二通道位于下半部分,上半部分和下半部分相连通,且第一通道的侧壁渐扩设置,使得槽口处便于过线,同时,槽口的上半部分倾斜设置还能够便于密封胶的灌注,使得密封胶能够沿着倾斜设置的壁面向槽口的槽底部分流动,提升密封胶对线圈切面的密封效果。
在具体应用中,槽口大致呈U形,第一通道的侧壁呈斜面形,的人通道的侧壁呈大致平直的。
在上述任一技术方案中,进一步地,线槽的宽度大于槽口的宽度。
在该技术方案中,线圈的线头部和线尾部均设置在槽口内,便于线圈的入槽,线槽的宽度比槽口的宽度大,使得线头部和线尾部进入槽口时与槽口连接的更加紧密,提升了槽口对线圈的固定性。

进一步地,绝缘盖板与绝缘骨架的凸起部相卡接。
在具体应用中,绝缘盖板上设置有卡扣,卡扣与凸起部相卡接。可以理解的是,凸起部的长度短于端子容纳部的长度,因此卡扣与凸起部的卡接得到了保证。
进一步地,任一分块铁芯包括多个冲片,多个冲片沿定子铁芯的轴向层叠分布。
在该技术方案中,设置每一个分块铁芯包括多个冲片,多个冲片沿定子铁芯的轴向层叠分布,这样交叠部形成于冲片的周侧边缘,在多个冲片沿铁芯的轴向层叠分布时,相邻冲片之间限定出交叠缝隙,并形成于形成定子槽中,便于绕组缠绕在定子铁芯的齿部上,并位于定子槽内。

本申请提供的绝缘骨架,包括第一支架、第二支架和第三支架,第二支架和第一支架呈相对设置方式分布,第三支架设置在第一支架和第二支架之间,并且第三支架的一端与第一支架连接,第三支架的另一端与第二支架连接,使得第一支架、第二支架和第三支架三者连接为一体。其中,绝缘骨架还包括端子容纳部,端子容纳部设置在第二支架上,压接端子设置在端子容纳部内,同相的线圈通过压接端子在端子容纳部内进行连接,使得同相的线圈进行串联。其中,端子容纳部设置在第二支架背离第一支架的一侧,进而避免对线圈绕设空间的占用。同时,端子容纳部和线槽沿第一方向分布,便于线圈的绕设以及同相线圈的串联。另外,通过在绝缘骨架上设置端子容纳槽,通过压接端子实现每一项线圈的电连接,避免了在绝缘骨架上方叠加其他实现同相电连接的结构,进而降低了定子整体的尺寸。
其中,第一方向为定子铁芯的周向方向。

在具体应用中,绝缘盖板上设置有卡扣,卡扣与凸起部相卡接。可以理解的是,凸起部的长度短于端子容纳部的长度,因此卡扣与凸起部的卡接得到了保证。
进一步地,任一分块铁芯包括多个冲片,多个冲片沿定子铁芯的轴向层叠分布。
在该技术方案中,设置每一个分块铁芯包括多个冲片,多个冲片沿定子铁芯的轴向层叠分布,这样交叠部形成于冲片的周侧边缘,在多个冲片沿铁芯的轴向层叠分布时,相邻冲片之间限定出交叠缝隙,并形成于形成定子槽中,便于绕组缠绕在定子铁芯的齿部上,并位于定子槽内。
具体地,冲片为硅钢片。
进一步地,相邻两个分块铁芯通过交叠部转动连接。
在该技术方案中,相邻的两个分块铁芯通过交叠部转动连接,即连接后的两个分块铁芯可相对转动。
通过使相邻的两个分块铁芯通过交叠部转动连接,可以使一个分块铁芯以交叠部的连接点为圆心,围绕另一个分块铁芯进行转动,此种连接方式简单可靠,便于操作者对定子铁芯的外形及结构进行调整,可根据使用需求对分块铁芯的位置进行调整。

定子铁芯还具有第二状态,由于相邻的两个分块铁芯为转动连接,当定子铁芯中两个相邻的分块铁芯相对运动时,多个分块铁芯可展开以呈大致直线形。展开后的各个分块铁芯的齿部大致呈直线分布,并且由于定子铁芯处于展开状态,相较于第一状态,两个齿部之间的定子槽的空间有所增大,便于操作者缠绕绕组。
通过使定子铁芯处于第二状态,可以使齿部大致呈直线分布,并使定子槽的空间增大,便于操作者缠绕绕组。在完成缠绕绕组的操作后,将定子铁芯合围成第一状态,使各个分块铁芯合围成圆形定子铁芯,以使定子铁芯的结构稳定可靠。

通过使第一冲片层和第二冲片层交替设置,在第一冲片层和第二冲片层的不同侧分别设置交叠部,并且使第一冲片层和第二冲片层在不同侧合围成交叠间隙,可以使两个相邻的分块铁芯通过交叠部和交叠间隙实现连接,具体地,使一个分块铁芯的交叠部插设于另一个分块铁芯的交叠间隙内。此种连接方式稳定可靠,操作者可快速对定子铁芯进行拆装,提高了工作效率。并且使多个分块铁芯采用同一结构即可实现相互连接,减少了分块铁芯的品类,提高了分块铁芯的通用性,降低了产品成本。

本发明的实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点,下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是,在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请,但是,本申请还可以采用其他不同于在此描述的其他方式来实施,因此,本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图12描述根据本申请一些实施例所述的绝缘骨架、定子、电机、压缩机和车辆。
实施例一:
如图1和图2所示,根据本申请的第一方面的一个实施例,本申请提出了一种绝缘骨架。绝缘骨架包括:第一支架1、第二支架2和第三支架3。
具体地,第二支架2与第一支架1相对设置,第二支架2上设有线槽20,线槽20贯穿第二支架2的壁面,线槽20的底壁的一部分向第二支架2的底部倾斜形成倾斜部22,倾斜部22位于线槽20朝向第一支架1的一侧;第三支架3设置在第一支架1和第二支架2之间并与第一支架1和第二支架2连接。
本申请提供的绝缘骨架,包括第一支架1、第二支架2和第三支架3,第二支架2和第一支架1呈相对设置方式分布,第三支架3设置在第一支架1和第二支架2之间,并且第三支架3的一端与第一支架1连接,第三支架3的另一端与第二支架2连接,使得第一支架1、第二支架2和第三支架3三者连接为一体。其中,第二支架2上设置有线槽20,线槽20包括底壁,线槽20的底壁向第二支架2的底部倾斜设置,形成倾斜设置的倾斜部22,其中,倾斜部22位于靠近第一支架1的一侧,这样,在通过绝缘骨架绕线时,线圈由线槽20背离第一支架1的一侧伸入线槽20,进而沿着倾斜部22向第一支架1的底部延伸,从而便于线圈的绕设,同时,线槽20能够对线圈进行预固定,使得线圈的绕设更加紧凑,提升线圈的固定性,提升定子铁芯4的槽满率。
在具体应用中,绝缘骨架应用于定子中,定子包括定子铁芯4、线圈和上述绝缘骨架,其中,绝缘骨架设置在定子铁芯4的轴线方向的两端,线圈绕设在绝缘骨架和定子铁芯4上。第一支架1、第二支架2和第三支架3合围出绕线容纳部,用于容纳线圈,定子铁芯4经过线槽20进线,使得线圈沿着倾斜部22向下倾斜,使得线圈绕设的更加紧密。
具体地,第一支架1、第二支架2和第三支架3一体成型而成。
可以理解的是,线槽20包括开口和与开口相对设置的底壁,线槽20的底壁的一部分向第二支架2的底部方向倾斜设置,以形成倾斜部22,并且,倾斜部22设置在线槽20朝向第一支架1的一侧,也即倾斜部22设置在第一支架1的内侧。也即,线槽20的上半部分呈大致U形,开口位于U形的顶部,线槽20的下半部分呈斜坡形,以使得过线时线圈更加紧凑,提升线圈绕设的固定性。
具体地,在将绝缘骨架应用到定子中时,第一支架1靠近定子铁芯4的内侧,第二支架2靠近定子铁芯4的外侧,第三支架3连接于第一支架1和第二支架2并位于两者之间。
实施例二:
如图3和图4所示,根据本申请的一个实施例,在上述实施例的基础上,进一步地:绝缘骨架还包括:端子容纳部24,端子容纳部24设于第二支架2背离第一支架1的一侧,用于容纳压接端子,沿第一方向,端子容纳部24位于线槽20的第一侧。
在该实施例中,绝缘骨架还包括端子容纳部24,端子容纳部24设置在第二支架2上,压接端子设置在端子容纳部24内,同相的线圈通过压接端子在端子容纳部24内进行连接,使得同相的线圈进行串联。其中,端子容纳部24设置在第二支架2背离第一支架1的一侧,进而避免对线圈绕设空间的占用。同时,端子容纳部24和线槽20沿第一方向分布,便于线圈的绕设以及同相线圈的串联。另外,通过在绝缘骨架上设置端子容纳槽240,避免了在绝缘骨架上方叠加其他市县同相电连接的 结构,进而降低了定子整体的尺寸。
其中,第一方向为定子铁芯4的周向方向。
实施例三:
如图1和图3所示,根据本申请的一个实施例,在上述实施例的基础上,进一步地:端子容纳部24包括:容纳槽240,用于容纳压接端子,容纳槽240上设有槽口2400,槽口2400位于容纳槽240沿第一方向的侧壁上;溢胶槽242,沿第一方向,溢胶槽242位于容纳槽240的两侧,溢胶槽242与槽口2400连通。
在该实施例中,端子容纳部24包括容纳槽240和溢胶槽242,容纳槽240用于容纳定子的压接端子,其中,容纳槽240上设置有槽口2400,同相线圈的线头部和线尾部由容纳槽240一侧的槽口2400伸入容纳槽240,对线圈起到定位的作用,保证线圈的稳定性,同时通过压接端子实现同相线圈的电连接。
另外,溢胶槽242设置在容纳槽240的两侧,并与槽口2400相连通,这样,在通过接线端子将同相线圈电连接后,在容纳槽240和槽口2400处通过密封胶对线圈进行密封,提升线圈的安全性能,并且,由于溢胶槽242的设置,使得在通过密封胶密封压接端子的过程中,多余的密封胶会被溢胶槽242阻挡,使得密封胶不会外溢到端子容纳部24外侧,实现对线圈的较好密封。
在具体应用中,容纳槽240上设置有两个槽口2400,两个槽口2400分别设置在容纳槽240在第一方向上的两个侧壁上。同样地,溢胶槽242的数量为两个,两个溢胶槽242分别与两个槽口2400对应设置,使得在两个槽口2400处进行密封时,在两个槽口2400处均能通过溢胶槽242避免密封胶溢出。
可以理解的是,当对压接端子和导线切除断面进行密封时,采用粘性低的胶密封胶时,密封胶顺着容纳槽240的侧壁,很容易流走,难以实现对压接端子和导线切除断面完全的密封。采用粘性高的密封胶时,由于密封胶的流动性不高,而容纳槽240的槽口2400比较狭窄,很难完全覆盖。因此,本申请通过设置溢胶槽242,能够避免密封胶溢出,实现压接端子和线圈导线切面的完全密封。
实施例四:
如图2和图3所示,根据本申请的一个实施例,在上述实施例的基础上,进一步地:端子容纳部24还包括:溢胶台244,沿第一方向,溢胶台244设于容纳槽240的两侧;凸台246,设于溢胶台244,至少凸台246与溢胶台244合围出溢胶槽242。
在该实施例中,端子容纳部24还包括溢胶台244和凸台246,溢胶台244设置在容纳槽240的两侧,也即在容纳槽240第一方向的两侧具有凸出的溢胶台244,凸台246设置在溢胶台244上,使得至少溢胶台244与凸台246合围出溢胶槽242,使得溢胶槽242包围于槽口2400的至少一部分,进而在向容纳槽240以及槽口2400内浇灌密封胶进行密封时,多余的密封胶能够流进溢胶槽242内,避免密封胶溢出端子容纳部24。
可以理解的是,压接端子将线圈刺破,使得同相线圈进行连接。
在具体应用中,压接端子为刺破式端子,从而在压接端子压向容纳槽240内的线圈的过程中,能够刺破线圈表面的绝缘覆膜,从而实现同相线圈的电连接,以实现快速连接。
进一步地,如图2所示,凸台246包括:第一凸台2460,设于容纳槽240远离线槽20的一侧,第一凸台2460位于槽口2400远离第一支架1的一侧;第二凸台2462,设于容纳槽240靠近线槽20的一侧,第二凸台2462与第二支架2、容纳槽240合围出溢胶槽242,第二凸台2462与容纳槽240之间设有缺口。
在该实施例中,凸台246包括第一凸台2460和第二凸台2462,第一凸台2460和第二凸台2462分别设置在容纳槽240两侧的溢胶台244上,其中,第一凸台2460设置在容纳槽240远离线槽20的一侧,且位于槽口2400远离第一支架1的一侧,这样,在向容纳槽240和槽口2400内注入密封胶时,多余的密封胶会被第一凸台2460阻挡,避免了密封胶溢出。
第二凸台2462设置在容纳槽240靠近线槽20的一侧,并且,第二凸台2462与第二支架2的表面、以及容纳槽240的外侧壁面合围出溢胶槽242,其中,第二凸台2462的端部与容纳槽240的壁面之间未完全闭合,具有缺口,从而便于线圈的线尾的切断和密封。
在具体应用中,第一凸台2460的底部设有走线槽20,走线槽20与槽口2400相对设置,使得线圈能够在走线槽20内进一步固定,提升线圈的牢固性。
另外地,缺口的尺寸较小进而避免密封胶流出。具体地,缺口的宽度大于或等于1mm,且小于或等于5mm。
实施例五:
如图5所示,根据本申请的一个实施例,在上述实施例的基础上,进一步地:槽口2400包括相连通的第一通道2402和第二通道2404,第一通道2402位于第二通道2404的顶部,第一通道2402的侧壁向第一通道2402的两侧渐扩设置。
在该实施例中,槽口2400包括相连通的第一通道2402和第二通道2404,也即槽口2400分为上半部分和下半部分,其中,第一通道2402位于上半部分,第二通道2404位于下半部分,上半部分和下半部分相连通,且第一通道2402的侧壁渐扩设置,使得槽口2400处便于过线,同时,槽口2400的上半部分倾斜设置还能够便于密封胶的灌注,使得密封胶能够沿着倾斜设置的壁面向槽口2400的槽底部分流动,提升密封胶对线圈切面的密封效果。
在具体应用中,槽口2400大致呈U形,第一通道2402的侧壁呈斜面形,的人通道的侧壁呈大致平直的。
实施例六:
根据本申请的一个实施例,在上述实施例的基础上,进一步地:线槽20的宽度大于槽口2400的宽度。
在该实施例中,线圈的线头部和线尾部均设置在槽口2400内,便于线圈的入槽,线槽20的宽度比槽口2400的宽度大,使得线头部和线尾部进入槽口2400时与槽口2400连接的更加紧密,提升了槽口2400对线圈的固定性。
在具体应用中,线槽20的宽度也即沿第一方向线槽20的宽度,槽口2400的宽度也即沿第二方向槽口2400的宽度。具体地,线槽20和槽口2400均大致呈U形,线槽20的宽度和槽口2400的宽度也即U形的左右两侧侧壁的距离。
通过上述槽口2400和线槽20宽度的设置,一方面使得槽口2400内能够同时容纳线圈的线头部和线尾部,一方面还能提升线圈的紧密性。
实施例六:
如图6、图7和图9所示,根据本申请的一个实施例,在上述实施例的基础上,进一步地:绝缘骨架还包括:凸起部26,设于第二支架2背离第一支架1的一侧,沿第一方向,凸起部26位于线槽20的第二侧。

具体地,对于分块铁芯,每个分块铁芯上均绕设有一个线圈,每个线圈包括线头部和线尾部,绕设完毕后线尾部由凸起部26的底部伸入线槽20内,通过线槽20对线圈进行限位。
可以理解的是,沿第一方向,线槽20包括第一侧和第二侧,线槽20的第一侧和线槽20的第二侧为线槽20相对设置的两侧,其中,线槽20靠近端子容纳部24的一侧为线槽20的第一侧,线槽20靠近凸起部26的一侧为线槽20的第二侧。
实施例七:
如图6和图7所示,根据本申请的一个实施例,在上述实施例的基础上,进一步地:凸起部26的顶壁的至少一部分向第二支架2的底部倾斜设置。
在该实施例中,凸起部26的顶壁的至少一部分向第二支架2的底部倾斜设置,一方面降低了凸起部26使用的材料,降低了生产成本,另一方面,在绝缘骨架与其他结构配合使用时,避免了对其他结构的干涉。
在具体应用中,凸起部26的截面大致呈三角形。
在具体应用中,电机包括定子铁芯4、绝缘骨架和绝缘盖板6,绝缘骨架设置在定子铁芯4的两端,绝缘盖板6设置在绝缘骨架远离定子铁芯4的两端。绝缘盖板6起到了绝缘的作用,提升了电机的安全性能。其中,凸起部26与绝缘盖板6相卡接,使得绝缘骨架和绝缘盖板6相连接,提升了绝缘盖板6和绝缘骨架连接的可靠性。
可以理解的是,绝缘盖板6和绝缘骨架均通过绝缘材料制造而成。
进一步地,凸起部26靠近第二支架2底部的表面,位于线槽20的底壁远离第二支架2底部的一侧。
在该实施例中,凸起部26靠近第二支架2的底部的表面,位于线槽20的底壁远离第二支架2底部的一侧,通过上述设置,使得凸起部26靠近第二支架2底部的表面,高于线槽20的底壁,也即线槽20的底壁低于凸起部26的下表面,进而线圈的线尾部由凸起部26远离线槽20的一侧绕向线槽20,能够避免线圈在线槽20处出现弯折,进而使得线圈的走线更加紧密。
具体地,凸起部26的下表面和线槽20的底壁之间的距离差值大于或等于线圈中的导线的直径。可以理解的是,一根导线绕设在分块铁芯和绝缘骨架上形成线圈。
进一步地,端子容纳部24凸出于第二支架2的长度,大于凸起部26凸出于第二支架2的长度。
在该实施例中,端子容纳部24和凸出部均向远离第一支架1的一侧凸出于第二支架2,其中,凸出部凸出于第二支架2的长度,短于端子容纳部24凸出于第二支架2的长度,这样,在绝缘骨架与绝缘盖板6连接时,避免了对两者连接产生干涉,保证了两者的连接可靠性。
可以理解的是,第二支架2、第三支架3和第一支架1沿第二方向依次分布,凸出部沿第二方向的长度小于端子容纳部24的长度。
可以理解的是,第二方向为定子铁芯4的径向方向。
实施例八:

在该实施例中,绝缘骨架还包括标记29,标记29设置在第二支架2和第一支架1中的至少一者上,可以理解的是,绕制不同的定子时,会对应不同的线圈直径,进而对应不同的辅助槽30的宽度、不同的槽口2400宽度,也即,线圈的直径是与槽口2400的宽度、辅助槽30的宽度一一对应的,因此,线圈的直径与槽口2400的宽度、辅助槽30的宽度同步变化,因此,本申请提出的实施例在绝缘骨架上设置标记29,标记29与线圈的直径、槽口2400的宽度和辅助槽30的宽度一一对应,这样,用于可根据不同的线圈直径,依据标记29来选择不同的绝缘骨架,具体地,不同的绝缘骨架对应不同尺寸的槽口2400宽度和辅助槽30宽度,从而使得多种尺寸规格的绝缘骨架能够适应不同尺寸的线圈。

进一步地,绕组5包括多个线圈,一个分块铁芯和分块铁芯两端的绝缘骨架上绕设有一个线圈,线圈包括线头部和线尾部,线槽20用于容纳线头部和线尾部。

其中,线圈包括线头部和线尾部,线槽20用于容纳线头部和线尾部,保证线圈绕制的紧密性。
具体地,线头部卡设在定子铁芯4轴线方向上一端的线槽20内,然后向定子铁芯4另一端延伸,并自绝缘骨架远离线槽20的一侧开始绕设,进而使得线尾部位于绝缘骨架靠近线槽20的一侧,然后将线尾部绕至台阶部28,经过台阶部28上表面伸至凸起部26的下方,进而伸到线槽20内,在线槽20内进行预先固定。当所有的线圈均绕设完毕后,将多个分块铁芯合圆,形成定子,相比于现有技术,本申请提出的实施例,不仅能够提升定子的槽满率,还能够避免对线圈自身的绝缘层造成损伤。
进一步地,定子还包括:绝缘盖板6,绝缘盖板6设置在绝缘骨架背离定子铁芯4的一侧,绝缘盖板6与绝缘骨架的凸起部26卡接。
在该实施例中,绝缘骨架还包括绝缘盖板6,绝缘盖板6设置在绝缘骨架远离定子铁芯4的一侧,通过绝缘骨架的设置,能够实现对线圈两端的卷圆保护,提升定子的安全性能。其中,绝缘盖板6与绝缘骨架的凸起部26相连接,实现了对绝缘盖板6的固定,使得定子的整体结构更加紧凑,实现两者的有效锁合。
进一步地,绝缘盖板6与绝缘骨架的凸起部26相卡接。
在具体应用中,如图12所示,绝缘盖板6上设置有卡扣60,卡扣60与凸起部26相卡接。可以理解的是,凸起部26的长度短于端子容纳部24的长度,因此卡扣60与凸起部26的卡接得到了保证。
进一步地,任一分块铁芯包括多个冲片,多个冲片沿定子铁芯4的轴向层叠分布。
在该实施例中,设置每一个分块铁芯包括多个冲片,多个冲片沿定子铁芯4的轴向层叠分布,这样交叠部形成于冲片的周侧边缘,在多个冲片沿铁芯的轴向层叠分布时,相邻冲片之间限定出交叠缝隙,并形成于形成定子槽中,便于绕组5缠绕在定子铁芯4的齿部上,并位于定子槽内。
具体地,冲片为硅钢片。
进一步地,相邻两个分块铁芯通过交叠部转动连接。
在该实施例中,相邻的两个分块铁芯通过交叠部转动连接,即连接后的两个分块铁芯可相对转动。
通过使相邻的两个分块铁芯通过交叠部转动连接,可以使一个分块铁芯以交叠部的连接点为圆心,围绕另一个分块铁芯进行转动,此种连接方式简单可靠,便于操作者对定子铁芯4的外形及结构进行调整,可根据使用需求对分块铁芯的位置进行调整。
进一步地,定子铁芯4包括齿部和轭部,定子铁芯4至少具有第一状态和第二状态;在第一状态下,多个分块铁芯合圆形成第一环形,齿部位于轭部的内侧;在第二状态下,多个分块铁芯展开以呈大致直线形。

定子铁芯4还具有第二状态,由于相邻的两个分块铁芯为转动连接,当定子铁芯4中两个相邻的分块铁芯相对运动时,多个分块铁芯可展开以呈大致直线形。展开后的各个分块铁芯的齿部大致呈直线分布,并且由于定子铁芯4处于展开状态,相较于第一状态,两个齿部之间的定子槽的空间有所增大,便于操作者缠绕绕组5。
通过使定子铁芯4处于第二状态,可以使齿部大致呈直线分布,并使定子槽的空间增大,便于操作者缠绕绕组5。在完成缠绕绕组5的操作后,将定子铁芯4合围成第一状态,使各个分块铁芯合围成圆形定子铁芯4,以使定子铁芯4的结构稳定可靠。
进一步地,在第二状态下,处于两端的两个分块铁芯,在合圆后连接在一起,具体地,可在合圆后将两个分块铁芯进行焊接。

在该实施例中,多个冲片包括第一冲片层和第二冲片层,多个第一冲片和多个第二冲片沿定子铁芯4的轴向交替分布。第一冲片层在第一侧设置有交叠部,第一冲片层上的交叠部凸出于第二冲片层,由于多个第一冲片层和多个第二类冲片层交替设置,相邻的两个第一冲片层均凸出于设置于该相邻两个第一冲片层中间的第二冲片层,使得相邻的两个第一冲片层之间合围出交叠缝隙。第二冲片层在第二侧设置有交叠部,也即,第二冲片层在不同于第一冲片层的一侧设置有交叠部。第二冲片层上的交叠部凸出于第一冲片层,由于多个第一冲片层和多个第二类冲片层交替设置,相邻的两个第二冲片层均凸出于设置于该相邻两个第二冲片层中间的第一冲片层,使得相邻的两个第二冲片层之间也能够合围出交叠缝隙。
可以理解地,当多个第一冲片层和多个第二冲片层沿定子铁芯4的周向交替分布时,多个第一冲片层设置在第一侧的交叠部与多个第二冲片层设置在第二侧的交叠部交错设置。进一步地,位于相邻两个第一冲片层之间的交叠缝隙与位于相邻两个第二冲片层之间的交叠缝隙分别位于分块铁芯的两侧,且交错设置。
相邻的两个分块铁芯相互临近的一侧,分别设有交叠部和交叠缝隙,由于多个第一冲片层设置在第一侧的交叠部与多个第二冲片层设置在第二侧的交叠部交错设置,且位于相邻两个第一冲片层之间的交叠缝隙与位于相邻两个第二冲片层之间的交叠缝隙交错设置,一个分块铁芯的交叠部插设于另一个分块铁芯的交叠缝隙内,从而实现相邻两个分块铁芯的连接。
通过使第一冲片层和第二冲片层交替设置,在第一冲片层和第二冲片层的不同侧分别设置交叠部,并且使第一冲片层和第二冲片层在不同侧合围成交叠间隙,可以使两个相邻的分块铁芯通过交叠部和交叠间隙实现连接,具体地,使一个分块铁芯的交叠部插设于另一个分块铁芯的交叠间隙内。此种连接方式稳定可靠,操作者可快速对定子铁芯4进行拆装,提高了工作效率。并且使多个分块铁芯采用同一结构即可实现相互连接,减少了分块铁芯的品类,提高了分块铁芯的通用性,降低了产品成本。
进一步地,多个冲片包括交替设置的第一冲片层和第二冲片层;第一冲片层的第一侧设置有交叠部,第一冲片层上的交叠部凸出于第二冲片层,相邻两个第一冲片层合围出交叠缝隙;第二冲片层的第二侧设置有交叠部,第二冲片层上的交叠部凸出于第一冲片层,相邻两个第二冲片层合围出交叠缝隙;在相邻两个分块铁芯中,一个分块铁芯的交叠部插设于另一个分块铁芯的交叠缝隙内。

具体实施例:
如图1至图11所示,本申请提出的实施例,提供了一种绝缘骨架,用于定子,定子包括绕组5,绕组5绕设在绝缘骨架上。
其中,绝缘骨架的主体大致呈U形的形状布置,绝缘骨架包括第一支架1、第二支架2和第三支架3。第二支架2、第一支架1和第三支架3具有共同的基准面,其中沿基准面一侧的高度,第二支架2大于第一支架1,第一支架1大于第三支架3,共同形成了绕线容纳部。
第一支架1,在靠近绕线容纳部一侧的面,近似为平面,另一侧的面,为圆弧状。
如图8和图9所示,第二支架2主要沿大体垂直于基准面的方向向两侧延伸,第二支架2上具有连接凸起27,用于和定子铁芯4配合,将绝缘骨架固定在定子铁芯4上。从垂直于基准面的方向看去,依次分布有凸起部26,线槽20,端子容纳部24。

凸起部26有沿着基准面方向延伸的凸起,凸起在垂直于基准面方向为倾斜的,且凸起部26最外侧的形状边缘比端子容纳部24最外侧的形状边缘矮。
线槽20部分为上半部和下半部,上半部为中空部分,下半部具有斜坡形状的特征,上半部和下半部中间以台阶面进行划分。斜坡上边缘从台阶面开始,延伸到下边缘。下边缘与第三支架3的辅助槽30的表面呈大约对齐的方式。
端子容纳部24的两侧,有布置有用于容纳导线的槽口2400,槽口2400上半部为斜坡状的开口,下半部分为近似为U形的形状;端子容纳部24的中部,有大概中空呈矩形区域的容纳槽240,用来容纳压接端子。在槽口2400两侧有溢胶槽242,溢胶槽242为局部凸起或者半凸起形成的凹坑或者近似于凹坑的形状。
进一步地,线槽20的台阶面低于外侧凸起部26的下表面。
进一步地,线槽20的宽度,大于外侧端子容纳部24的槽口2400的宽度。
进一步地,线槽20靠近端子容纳部24的一侧,与第三支架3靠近凸起部26的一侧大致对齐。
进一步地,在端子容纳部24的平行于基准面的方向上,具有标记29,标记29可以为数字,字母或具有同等功能的符号。标记29的方式为,当绕线的线径发生变化时,端子容纳部24的槽口2400宽度,与辅助槽30的宽度,同步进行变化。
进一步地,在凸起部26的远离线槽20的一侧设置有台阶部28,且台阶部28的宽度小于线槽20的宽度。
进一步地,多个辅助槽30的宽度之和小于或者等于第三支架3的主体的宽度。辅助槽30沿着第三支架3的外表面自然延伸的时候,被第三支架3的侧表面直接平切,两者延伸交汇的最高点被称为辅助槽30侧面高度。
进一步地,第一支架1上设置有平坦但不贯穿的切口10。
进一步地,切口10的高度与辅助槽30侧面高度一致。
进一步地,线槽20的数量有且只有一个。相比于现有技术而言,本申请只需要一个线槽20,进而线槽20内同时容纳线头部和线尾部,使得线圈绕设的更紧凑。
进一步地,绝缘骨架的材料为耐温120℃以上的绝缘材料。具体地,绝缘骨架的材料为长期耐温120℃以上的绝缘材料。
进一步地,绝缘骨架应用于定子中,定子应用于电机中,压缩机包括电机。
具体地,车辆包括车体和压缩机,压缩机设置在车体内。
实施例十七:
如图1和图2所示,根据本申请的第六方面的一个实施例,本申请提出了一种绝缘骨架,包括:第一支架1、第二支架2和第三支架3。
具体地,第二支架2与第一支架1相对设置,第二支架2背离第一支架1的一侧设有端子容纳部24,端子容纳部24包括容纳槽240和溢胶槽242。其中,容纳槽240用于容纳压接端子,沿第一方向,容纳槽240相对设置的侧壁上设有槽口2400;沿第一方向,溢胶槽242位于容纳槽240的至少一侧,溢胶槽242与槽口2400连通;第三支架3位于第一支架1和第二支架2之间并与第一支架1和第二支架2连接。
本申请提供的绝缘骨架,包括第一支架1、第二支架2和第三支架3,第二支架2和第一支架1呈相对设置方式分布,第三支架3设置在第一支架1和第二支架2之间,并且第三支架3的一端与第一支架1连接,第三支架3的另一端与第二支架2连接,使得第一支架1、第二支架2和第三支架3三者连接为一体。其中,绝缘骨架还包括端子容纳部24,端子容纳部24设置在第二支架2上,压接端子设置在端子容纳部24内,同相的线圈通过压接端子在端子容纳部24内进行连接,使得同相的线圈进行串联。其中,端子容纳部24设置在第二支架2背离第一支架1的一侧,进而避免对线圈绕设空间的占用。同时,端子容纳部24和线槽20沿第一方向分布,便于线圈的绕设以及同相线圈的串联。另外,通过在绝缘骨架上设置端子容纳槽240,避免了在绝缘骨架上方叠加其他实现同相电连接的结构,进而降低了定子整体的尺寸。
其中,第一方向为定子铁芯4的周向方向。
进一步地,如图1和图3所示,端子容纳部24包括容纳槽240和溢胶槽242,容纳槽240用于容纳定子的压接端子,其中,容纳槽240上设置有槽口2400,同相线圈的线头部和线尾部由容纳槽240一侧的槽口2400伸入容纳槽240,对线圈起到定位的作用,保证线圈的稳定性,同时通过压接端子实现同相线圈的电连接。
另外,溢胶槽242设置在容纳槽240的两侧中的至少一侧,并与槽口2400相连通,这样,在通过接线端子将同相线圈电连接后,在容纳槽240和槽口2400处通过密封胶对线圈进行密封,提升线圈的安全性能,并且,由于溢胶槽242的设置,使得在通过密封胶密封压接端子的过程中,多余的密封胶会被溢胶槽242阻挡,使得密封胶不会外溢到端子容纳部24外侧,实现对线圈的较好密封。
在具体应用中,容纳槽240上设置有两个槽口2400,两个槽口2400分别设置在容纳槽240在第一方向上的两个侧壁上。同样地,溢胶槽242的数量为两个,两个溢胶槽242分别与两个槽口2400对应设置,使得在两个槽口2400处进行密封时,在两个槽口2400处均能通过溢胶槽242避免密封胶溢出。
可以理解的是,当对压接端子和导线切除断面进行密封时,采用粘性低的胶密封胶时,密封胶顺着容纳槽240的侧壁,很容易流走,难以实现对压接端子和导线切除断面完全的密封。采用粘性高的密封胶时,由于密封胶的流动性不高,而容纳槽240的槽口2400比较狭窄,很难完全覆盖。因此,本申请通过设置溢胶槽242,能够避免密封胶溢出,实现压接端子和线圈导线切面的完全密封。并且,对于线圈的线尾部进行密封时,能够实现线尾部的良好密封。
实施例十八:
如图2和图3所示,根据本申请的一个实施例,在上述实施例的基础上,进一步地:端子容纳部24还包括:溢胶台244,沿第一方向,溢胶台244设于容纳槽240的两侧;凸台246,设于溢胶台244,至少凸台246与溢胶台244合围出溢胶槽242。
在该实施例中,端子容纳部24还包括溢胶台244和凸台246,溢胶台244设置在容纳槽240的两侧,也即在容纳槽240第一方向的两侧具有凸出的溢胶台244,凸台246设置在溢胶台244上,使得至少溢胶台244与凸台246合围出溢胶槽242,使得溢胶槽242包围于槽口2400的至少一部分,进而在向容纳槽240以及槽口2400内浇灌密封胶进行密封时,多余的密封胶能够流进溢胶槽242内,避免密封胶溢出端子容纳部24。
可以理解的是,压接端子将线圈刺破,使得同相线圈进行连接。
在具体应用中,压接端子为刺破式端子,从而在压接端子压向容纳槽240内的线圈的过程中,能够刺破线圈表面的绝缘覆膜,从而实现同相线圈的电连接,以实现快速连接。
实施例十九:

其中,绝缘骨架的主体大致呈U形的形状布置,绝缘骨架包括第一支架1、第二支架2和第三支架3。第二支架2、第一支架1和第三支架3具有共同的基准面,其中沿基准面一侧的高度,第二支架2大于第一支架1,第一支架1大于第三支架3,共同形成了绕线容纳部。
第一支架1,在靠近绕线容纳部一侧的面,近似为平面,另一侧的面,为圆弧状。
第二支架2主要沿大体垂直于基准面的方向向两侧延伸,第二支架2上具有连接凸起27,用于和定子铁芯4配合,将绝缘骨架固定在定子铁芯4上。从垂直于基准面的方向看去,依次分布有凸起部26,线槽20,端子容纳部24。
第三支架3,由基准面向绕线容纳部一侧延伸,在靠近绕线容纳部一侧的面上,有用于辅助绕线时绕圈排列的辅助槽30,辅助槽30以阵列的方式在基准面的方向上展开。
凸起部26有沿着基准面方向延伸的凸起,凸起在垂直于基准面方向为倾斜的,且凸起部26最外侧的形状边缘比端子容纳部24最外侧的形状边缘矮。
线槽20部分为上半部和下半部,上半部为中空部分,下半部具有斜坡形状的特征,上半部和下半部中间以台阶面进行划分。斜坡上边缘从台阶面开始,延伸到下边缘。下边缘与第三支架3的辅助槽30的表面呈大约对齐的方式。
端子容纳部24的两侧,有布置有用于容纳导线的槽口2400,槽口2400上半部为斜坡状的开口,下半部分为近似为U形的形状;端子容纳部24的中部,有大概中空呈矩形区域的容纳槽240,用来容纳压接端子。在槽口2400两侧有溢胶槽242,溢胶槽242为局部凸起或者半凸起形成的凹坑或者近似于凹坑的形状。

进一步地,线槽20靠近端子容纳部24的一侧,与第三支架3靠近凸起部26的一侧大致对齐。
进一步地,在端子容纳部24的平行于基准面的方向上,具有标记29,标记29可以为数字,字母或具有同等功能的符号。标记29的方式为,当绕线的线径发生变化时,端子容纳部24的槽口2400宽度,与辅助槽30的宽度,同步进行变化。
进一步地,在凸起部26的远离线槽20的一侧设置有台阶部28,且台阶部28的宽度小于线槽20的宽度。
进一步地,多个辅助槽30的宽度之和小于或者等于第三支架3的主体的宽度。辅助槽30沿着第三支架3的外表面自然延伸的时候,被第三支架3的侧表面直接平切,两者延伸交汇的最高点被称为辅助槽30侧面高度。
进一步地,第一支架1上设置有平坦但不贯穿的切口10。
进一步地,切口10的高度与辅助槽30侧面高度一致。
进一步地,线槽20的数量有且只有一个。相比于现有技术而言,本申请只需要一个线槽20,进而线槽20内同时容纳线头部和线尾部,使得线圈绕设的更紧凑。
进一步地,绝缘骨架的材料为耐温120℃以上的绝缘材料。具体地,绝缘骨架的材料为长期耐温120℃以上的绝缘材料。
进一步地,绝缘骨架应用于定子中,定子应用于电机中,压缩机包括电机。
