用于直流有刷电机的端盖和包括该端盖的直流有刷电机
相关申请的交叉引用
本申请要求于2018年4月25日递交的中国专利申请第201820596355.5号的优先权和权益，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
技术领域
本申请涉及机械领域，特别涉及一种用于直流有刷电机的端盖和包括该端盖的直流有刷电机。
背景技术
有刷直流电机是直流电机的一种，其制造工艺成熟，已经被广泛应用于各个领域。现有技术中，直流有刷电机主要由外壳、定子、转子和端盖等部件构成。直流有刷电机的前后两端通过连接至转子的轴来输出动力。定子用于提供磁场。通电后，转子绕组的线圈在磁场中产生力矩，并通过转子上的换向器和端盖上的碳刷来换向以实现转子的持续转动。直流有刷电机的端盖上具有电源和两个碳刷，电源的正极连接至一个碳刷，电源的负极连接至另一个碳刷，从而形成经过电源的正极、第一碳刷、换向器、转子绕组、第二碳刷和电源的负极的供电电路以便为转子输送电能，在电源的正极和第一碳刷之间以及电源的负极和第二碳刷之间分别设置有一个棒型电感以改善电机的EMC(Electro Magnetic Compatibility，电磁兼容性)性能。
现有技术中，直流有刷电机的端盖上，在电源的正极和第一碳刷之间以及电源的负极和第二碳刷之间分别仅设置有一个棒型电感。棒型电感的电感量与其长度和线径有关。在不改变线径的情况下，如果需要增大电感量，只有增加棒型电感的长度，这会导致电机的端盖的轴向长度增加，进而导致整个电机的轴向长度增加。
发明内容
为了解决上述问题，本申请提供了一种用于直流有刷电机的端盖，其中，所述端盖上设置有电源、两个碳刷和两组串联的多个棒型电感，第一组串联的多个棒型电感的一端连接至所述电源的正极，第一组串联的多个棒型电感的另一端连接至第一碳刷，第二组串联的多个棒型电感的一端连接至第二碳刷，第二组串联的多个棒型电感的另一端连接至所述电源的负极。
可选地，每个棒型电感的长度能够被调节。
可选地，每组串联的多个棒型电感包括串联的两个棒型电感。
本申请还提供了一种直流有刷电机，其包括外壳、定子、转子和本申请提供的上述端盖，其中，所述转子上设置有换向器，两个碳刷与所述换向器滑动接触。
与现有技术相比，本申请的用于直流有刷电机的端盖和直流有刷电机至少具有以下优点：本申请中，通过在直流有刷电机的端盖上设置两组串联的多个棒型电感，从而能够在不增加电机轴向长度情况下增大电机的供电电路中的电感量，进而改善电机的EMC性能。另外，通过调节串联的多个棒型电感中的每个棒型电感的长度，可以调节串联的多个棒型电感的总电感量，使得同一电机具有更强的通用性。
附图说明
图1示出了根据本申请的一个具体实施方式的用于直流有刷电机的端盖。
图2示出了串联的两个棒型电感。
具体实施方式
下面参照附图描述根据本申请的实施例的用于直流有刷电机的端盖和包括该端盖的直流有刷电机。在下面的描述中，阐述了许多具体细节以便 使所属技术领域的技术人员更全面地了解本申请。但是，对于所属技术领域内的技术人员明显的是，本申请的实现可不具有这些具体细节中的一些。此外，应当理解的是，本申请并不限于所介绍的特定实施例。相反，可以考虑用下面的特征和要素的任意组合来实施本申请，而无论它们是否涉及不同的实施例。因此，下面的方面、特征、实施例和优点仅作说明之用而不应被看作是权利要求的要素或限定，除非在权利要求中明确提出。
图1示出了根据本申请的一个具体实施方式的用于直流有刷电机的端盖。图2中示出了串联的两个棒型电感。如图1和图2所示，直流有刷电机的端盖上装配有具有两个插针211和212的电源，两个碳刷221、222和四个棒型电感231、232、233、234。其中，插针211连接至电源的正极，插针212连接至电源的负极。棒型电感231和232串联在一起，棒型电感233和234串联在一起。每个棒型电感由芯棒和缠绕在芯棒周围的线圈构成。电源的插针211连接至棒型电感231的一脚，棒型电感231的另一脚连接至棒型电感232的一脚，棒型电感232的另一脚连接至碳刷221的刷辫。类似地，电源的插针212连接至棒型电感233的一脚，棒型电感233的另一脚连接至棒型电感234的一脚，棒型电感234的另一脚连接至碳刷222的刷辫。也就是说，供电电路中设置有两组串联的两个棒型电感。
图1中所示的直流有刷电机的端盖上装配有两组串联的两个棒型电感，本领域普通技术人员也可以根据实际需要设置每组串联的棒型电感中的电感数量，例如可以在每组串联的棒型电感中设置三个棒型电感，这些变型不脱离本申请的保护范围。
本申请中，通过在直流有刷电机的端盖上设置两组串联的多个棒型电感，从而能够在不增加电机轴向长度情况下增大电机的供电电路中的电感量，从而改善电机的EMC性能。另外，从成本的角度考虑，可以根据实际需要的电感量来选择各棒型电感的长度，以节约成本。
本申请中，通过在直流有刷电机的端盖上设置两组串联的多个棒型电感，从而能够在供电电路所需的电感量不变的情况下，通过减小每个棒型电感的长度，从而可能实现端盖的轴向长度减少，并进而实现电机总体的 轴向长度减少。
本申请中，由于串联的多个棒型电感中的每个棒型电感的长度可以被调节，从而可以调节串联的多个棒型电感的总电感量，使得同一电机具有更强的通用性。另外，也可以通过调节各棒型电感的线径或线圈匝数的方式对总电感量进行调节。
本申请的直流有刷电机可以作为各种汽车电动尾门升降系统中的直流电机。本领域普通技术人员也可以根据实际需要将本申请的直流有刷电机应用于其它合适的场合。
虽然本申请已以较佳实施例披露如上，但本申请并非限定于此。任何本领域技术人员，在不脱离本申请的精神和范围内所作的各种更动与修改，均应纳入本申请的保护范围内，因此本申请的保护范围应当以权利要求所限定的范围为准。
