上面对本申请实施例中继电器的电磁机构进行了描述，下面对本申请实施例中的驱动机构进行描述：
请参阅图4，本申请实施例中继电器的驱动机构(q)包括线圈架(a)、第一动铁芯(d)、第二动铁芯(d)、触头安装槽(z)以及触头导轨(x)，请参阅图5，图5为驱动机构的另一视图，如图5所示，线圈架(a)的内部为空腔(v)，在该驱动机构中，线圈架(a)可以用于设置线圈(u)，空腔(v)可以为推杆提供定位，起到内导轨的作用，同时限制触头导轨侧的偏移；触头安装槽(z)可以为动触头组件(2g)提供安装限位，触头导轨(x)可以为推杆的触头侧提供导向。
需要说明的是，为了解决现有技术中继电器的驱动机构连杆多以及传动效率低的缺点，本申请实施例中继电器的驱动机构可以一体化成型，从而大幅减少所需的传动零件，具体的，请参阅图6，图6为本申请实施例中继电器的驱动机构的装配示意图，如图6所示，可以使用注塑模具对驱动机构(q)加工，从而不需要进行额外的装配，通过将第一动铁芯(d)以及第二动铁芯(d)固定在注塑模具中与安装槽(q1)对应的位置，然后进行一次性注塑成型，即可得到本申请实施例中的驱动机构，通过该加工方法，可以减少零部件的安装间隙，有效提高动力传递效率，降低系统损耗，提高运动精准度。
或者，驱动机构也可以为第一驱动机构以及第二驱动机构分别进行一体化成型，这之后再将第一驱动机构与第二驱动机构进行连接固定从而得到驱动机构，请参阅图7，图7为本申请实施例中继电器的驱动机构的另一装配示意图，如图7所示，驱动机构可以包括第一驱动机构(a1)、第二驱动机构(a3)以及连接件(a2)，通过将连接件(a2)插入第二驱动机构(a3)上的第二矩形连接孔(a31)以及第一驱动机构(a1)上的第一矩形连接孔(a11)，即可完成对驱动机构的装配，需要说明的是，连接件(a2)具体可以为插销。
上面对本申请实施例中继电器的电磁机构以及驱动机构分别进行了描述，下面对电磁机构以及驱动机构的装配关系进行描述：
请参阅图8，图8为本申请实施例中继电器的电磁机构与驱动机构的装配关系示意图，如图8所示，顶盖(f)与轭铁以及驱动机构(q)固定连接，空腔(v)内部用于设置 静铁芯(c)、第一副永磁体(e)以及第二副永磁体(e)；
请参阅图9，图9为本申请实施例中电磁机构与驱动机构装配的另一视角示意图，如图9所示，线圈架(a)可以用以缠扰线圈(u)，线圈(u)通电之后在第一主永磁体(g)、第二主永磁体(g)、第一副永磁体(e)以及第二副永磁体(e)产生的磁场作用下进行运动，线圈(u)的运动可以带动驱动机构(q)的运动，当第一动铁芯(d)与顶盖(f)贴合时，第一副永磁体(e)、第一动铁芯(d)、顶盖(f)以及第一主永磁体(g)配合提供位置(1)处的保持力，当第二动铁芯(d)与轭铁(b)贴合时，轭铁(b)、第二副永磁体(e)、第一动铁芯(d)以及第二主永磁体(g)配合提供位置(2)处的保持力；
请参阅图10，图10为本申请实施例中电磁机构与驱动机构配合的另一视角的示意图，具体位置关系与上述图9所示的一致，此处不再赘述。
具体的，线圈(u)在线圈架(a)进行运动的原理请参阅图11，如图11所示，线圈即为图11中的通电导线，在永磁体提供的磁场的作用下，改变线圈中电流的方向，即可改变线圈(u)在线圈架(a)的上下运动，并且在全程的运动过程中，主运动气隙保持不变，能够提供稳定的电磁输出，具有运动行程长以及出力稳定的特点。
请参阅图12，图12为本申请实施例中电磁机构与驱动机构装配前的示意图，电磁机构与驱动机构(q)的装配可以是先将顶板(f)与驱动机构(q)进行固定连接，然后将驱动机构(q)推入电磁机构中，最后将顶盖(f)和轭铁(b)进行铆接固定。
需要说明的是，本申请实施例中继电器的电磁机构还可以通过顶盖(f)以及轭铁(b)调节保持力，具体的，随着线圈(u)中电流方向的改变，驱动机构(q)的运动会使得第一动铁芯(d)与顶盖(f)贴合，或者使得第二动铁芯(d)与轭铁(b)贴合，请参阅图3a、图3b、图3c以及图13，顶盖(f)上开设有第一开口组(h)，轭铁(b)上开设有第二开口组(i)，其中，第一开口组(h)包括第一子开口组(h1)以及第二子开口组(h2)，第一子开口组位于顶盖(f)用于与第一动铁芯(d1)接触的第一接触部(T1-1)上，第二子开口组位于顶盖(f)用于与第一动铁芯(d1)接触的第二接触部(T1-2)上；相应的，第一动铁芯(d1)上也有两个对应的接触部(t1-1与t1-2)分别用于与第一接触部(T1-1)以及第二接触部(T1-2)接触。需要说明的是，图3c中的中虚线框标识的接触部为粗略示意，本领域技术人员可以结合图中元器件的关系以及大小来确定真正接触的部分。每个子开口组可以包括一个或多个开口，例如，在图13中，每个子开口组(h1、h2)都包括一个第一子开口。子开口组的数量可以跟第一动铁芯(d1)上的接触部的数量相对应，图3c以及图13中，由于第一动铁芯(d1)只有两个侧边的接触部(t1-1以及t1-2)，因此可以只设置两个子开口组，当然，也可以只设置一个子开口组。其中，第一子开口组(h1)或者第二子开口组(h2)可以包括一个或者多个第一子开口，在图13中，各个子开口组均只包括一个第一子开口。
第二开口组(i)包括第三子开口组(i1)以及第四子开口组(i2)，第三子开口组(i1)位于轭铁(b)用于与第二动铁芯(d2)接触的第三接触部(T2-1)上，第四子开口组(i2)位于轭铁(b)用于与第二动铁芯(d2)接触的第四接触部(T2-2)上；相应的，第二动铁芯(d2)上也有两个对应的接触部(t2-1与t2-2)分别用于与第三接触部(T2-1)以及第 四接触部(T2-2)接触。需要说明的是，图3c中的中虚线框标识的接触部为粗略示意，本领域技术人员可以结合图中元器件的关系以及大小来确定真正接触的部分，同时，由于第三接触部(T2-1)与第四接触部(T2-2)在图3c中有被轭铁(b)遮挡，本领域技术人员可结合其他附图(如图3a)来了解第三接触部与第四接触部的具体位置。每个子开口组都可以包括一个或多个开口，例如，在图13中，每个子开口组(i1、i2)都包括一个第二子开口。子开口组的数量可以跟接触部的数量相对应，图3c以及图13中，由于第二动铁芯(d2)只有两个侧边的接触部(t2-1以及t2-2)，因此可以只在轭铁(b)上设置两个子开口组，当然，也可以只设置一个子开口组。其中，第三子开口组(i1)或者第四子开口组(i2)可以包括一个或者多个第二子开口，在图13中，各个子开口组均只包括一个第二子开口。
需要说明的是，其保持力调整原理为通过改变并联磁阻的方式调整保持力，请参阅图14，图14为顶盖(f)处的保持力调整孔示意图，如图14所示，第一动铁芯(d)与顶盖(f)贴合，通过增大顶盖(f)的第一开口组(h)的大小，进而增加顶盖的磁阻，磁通从顶盖(f)的第一开口组(h)向第一动铁芯(d)移动，相当于增大了经过第一动铁芯(d)的磁通，从而提高保持力；请参阅图15，图15为轭铁(b)处的保持力调整孔示意图，如图15所示，第二动铁芯(d)与轭铁(b)贴合，通过增大轭铁(b)上的第二开口组(i)的大小，进而增加了轭铁(b)的磁阻，磁通从第二开口组(i)向第二动铁芯(d)移动，相当于增大了经过第二动铁芯(d)的磁通，进而增大了保持力。
请参阅图16，图16的左侧为开设了第一开口组(h)的顶盖(f)以及开设了第二开口组(i)的轭铁(b)的截面图，图16的右侧为没有开设第一开口组(h)的顶盖(f)以及没有开设第二开口组(i)的轭铁(b)的截面图，如图16所示，在图16的左侧，通过轭铁(b)再经过第一动铁芯(d)以及第二动铁芯(d)，最后再回到轭铁(b)的电磁线要比图16的右侧的明显增多，这些电磁线为第一动铁芯(d)以及第二动铁芯(d)提供了保持力，而在右侧图中，经过轭铁(b)的电磁线几乎没有再流过第一动铁芯(d)以及第二动铁芯(d)，因此提供的保持力不足。
进一步地，在本申请实施例中，通过调节第一开口组(h)以及第二开口组(i)的大小，即可对保持力作出调整。
下面对本申请实施例中的永磁体排布方式进行描述：
请参阅图17，图17为本申请实施例中永磁体排布方式的一个示意图，如图所示，沿图的顶部到底部的方向即为长度方向，第一主永磁体(g)以及第二主永磁体(g)的长度比第一副永磁体(e)以及第二副永磁体(e)的长度要大，并以静铁芯(c)为中心分为左右两侧，不同侧中线圈(u)中的电流流动方向相反，第一主永磁体(g)、第二主永磁体(g)、第一副永磁体(e)以及第二副永磁体(e)负责提供磁场，采用这种永磁体排布方式可以额外提高磁场覆盖面积，图中阴影部分即为增加的磁场覆盖面积，需要说明的是，图中的阴影部分只标注出了四分之一。图中的线圈(u)中的电流可以得到更高效的利用，同时在额外增加的磁场与线圈(u)的共同作用下，线圈中的电流的整体流动方向与磁场垂直，减少了偏心的可能性。
下面对本申请实施例中的动触头组件进行描述：
请参阅图18a，图18a中动触头组件(2g)通过触头安装槽(z)与驱动机构(q)固定连接，图18a中还展示了线圈(u)与驱动机构(q)的装配关系，将线圈(u)安装到驱动机构(q)上的线圈架(a)处，即可完成装配。
请参阅图18b，图18b为动触头组件(2g)与驱动机构(q)装配的另一视角示意图，如图所示，动簧片(2g2)装配在动触头组件(2g)中，动簧片(2g2)采用分体设计，依靠气体绝缘，保证了电气间隙的可靠。
下面对本申请实施例中继电器的动触头组件(2g)进行描述：
请参阅图19，本申请实施例中动触头组件(2g)包括调整块(2g1)、动簧片(2g2)、弹簧板支撑(2g3)以及中间支架(2g4)，其中，中间支架(2g4)的两侧设置了腰圆凸台(2gb)，调整块(2g1)、动簧片(2g2)以及弹簧板支撑(2g3)上均设置了腰圆孔(2ga)用于进行定位，具体的装配方式可以是各零件按照图19中所示位置依次通过腰圆凸台(2gb)与腰圆孔(2ga)配合的方式进行连接，需要说明的是，本申请实施例中的动簧片(2c)可以采用柔性可变形材料，可以减少弹跳，且动簧片(2g2)与弹簧板支撑(2g3)连接，进一步降低了弹跳。
下面对本申请实施例中继电器的静触头组件进行描述：
请参阅图20，图20为本申请实施例中静触头组件与基座的装配示意图，如图所示，本申请实施例中静触头组件包括静簧片(1g)、线圈引脚簧片(1e)以及吹弧永磁铁(2f)，其中，静簧片(1g)上铆接有静触点(1ga)，静簧片通过插接的方式固定在基座(3)上的第一槽口(3b)中，线圈引脚簧线(1e)通过插接的方式，固定在基座(3)上的第二槽口(3c)中，吹弧永磁铁(2f)通过插接的方式固定在基座(3)上的第三槽口(3a)中，实现快速灭弧，需要说明的是，本申请实施例中静簧片(1g)采用刚性材料，不容易发生形变。
图21为本申请实施例中静触头组件与基座装配的另一视角示意图，具体装配方式与图20所述的装配方式一致，此处不再赘述。
需要说明的是，在本申请实施例中，动触头组件以及静触头组件可以为一组，或者也可以为多组，具体此处不做限定。
请参阅图22，本申请实施例中继电器还包括上盖(5)以及触电系统部件(4a)，该触电系统部件(4a)上设置有塑料栅片，可以用于快速灭弧。
请参阅图23，本申请实施例中继电器还包括卡扣(2e)，电磁机构与驱动机构装配完成后可以作为一体化驱动机构(4)，继电器的装配方式可以为，先将一体化驱动机构(4)插入到基座(3)中，接着通过卡扣(2e)连接一体化驱动机构(4)上的触头导轨(x)以及基座(3)，卡扣(2e)既可以对一体化驱动机构(4)以及基座(3)进行连接固定，还可以为一体化驱动机构(4)提供导向作用，请参阅图24，软性连接导体(2w)可以实现线圈(u)上的电流的输送；最后合上上盖(5)，请参阅图25，继电器在装配完成之后，基座(3)底部会引出线圈引脚(2y)。
本申请实施例中，线圈(u)在线圈架(a)上位置(1)或者位置(2)的运动可以进 一步带动一体化驱动机构(4)在基座(3)上沿着触头导轨(x)的轴向运动，进而实现动簧片(2g2)与静簧片(1g)的接触，从而可以实现电源的切换。
在本申请实施例中，可以通过顶盖(f)上的第一开口(h)以及轭铁(b)上的第二开口(i)增强保持力，并且可以通过调节第一开口(h)以及第二开口(h)的大小对保持力的大小进行调节，在本申请实施例中，永磁体提供了磁场，因此不再需要额外的励磁时间，并且由于线圈(u)的运动方式为沿着线圈架(a)上下运动，因此能大大缩短在分闸位和合闸位的切换时间，进而实现了继电器对电源的高速切换。
请参阅图26，本申请实施例中还提供了继电器中电磁机构的另一种形式，如图所示，该电磁机构包括静铁芯(2c)、第一主永磁体(2z)、第二主永磁体(2z)、第三主永磁体(2z)、第四主永磁体(2z)、第一副永磁体(2v)、第二副永磁体(2v)以及第三副永磁体(2v)，这其中，第一主永磁体(2z)、第二主永磁体(2z)、第三主永磁体(2z)以及第四主永磁体(2z)属于主永磁体组，第一副永磁体(2v)、第二副永磁体(2v)以及第三副永磁体(2v)属于副永磁体组，该电磁机构还包括轭铁(b)以及顶盖(f)，其中，静铁芯(2c)、第一主永磁体(2z)、第二主永磁体(2z)、第三主永磁体(2z)、第四主永磁体(2z)、第一副永磁体(2v)、第二副永磁体(2v)、第三副永磁体(2v)以及顶盖(f)与轭铁(b)铆接固定，具体铆接方式与上述图3a至图3c所示的铆接方式类似，具体此处不再赘述。
如图26所示，第一副永磁体(2v)、第二副永磁体(2v)以及第三副永磁体(2v)环绕设置于静铁芯(2c)，第一主永磁体(2z)、第二主永磁体(2z)、第三主永磁体(2z)以及第四主永磁体(2z)环绕设置于第一副永磁体(2v)、第二副永磁体(2v)以及第三副永磁体(2v)，且第一主永磁体(2z)、第二主永磁体(2z)、第三主永磁体(2z)以及第四主永磁体(2z)的长度相等，第一副永磁体(2v)、第二副永磁体(2v)以及第三副永磁体(2v)的长度相等，第一主永磁体(2z)的长度大于第一副永磁体(2v)的长度，第一主永磁体(2z)、第二主永磁体(2z)、第三主永磁体(2z)以及第四主永磁体(2z)彼此垂直设置，图中所示“S”和“N”即为永磁体的磁极，图中所有永磁体的“N”极朝向静铁芯(2C)，采用这样的电磁机构结构设置，可以使得线圈(u)能够完全被永磁体所提供的磁场包围，更大程度上提高了磁场的利用效率，完全杜绝了线圈(u)与继电器其他部件的接触，提高了电磁机构的使用寿命以及可靠性。
需要说明的是，图中箭头“Y”所指向的方向，即为上述永磁体的长度方向。
需要说明的是，在实际的应用中，该电磁机构中的主永磁体可以不包括第一主永磁体(2z)、第二主永磁体(2z)、第三主永磁体(2z)以及第四主永磁体(2z)，还可以是其他数量的主永磁体，或者是其他形状的永磁体，例如是圆形永磁体，只需要保证其提供的磁场能够将线圈(u)完全包围即可，具体不做限定；副永磁体也是其他的形式，例如也可以采用方形的副永磁体，只需要保证副永磁体可以将静铁芯(2c)完全包围即可；线圈(u)也可以为圆形线圈或者方形线圈，具体此处不做限定。
具体的，该电磁机构与继电器其余组件的装配，与之前所示实施例的类似，此处不再赘述。
本申请实施例还提供了另一种继电器，该继电器的包括电磁机构，请参阅图27，如图所示，该电磁机构包括第一永磁体(3z)、第二永磁体(3z)、导磁材料外壳(2k)、绝缘容纳件(2j)、动铁芯(3d)、第一线圈(3u)以及第二线圈(3u),这其中，第一永磁体(3z)的导磁方向与第二永磁体(3z)的导磁方向相反，绝缘容纳件(2j)内部开设有空腔，第一永磁体(3z)以及第二永磁体(3z)设置于绝缘容纳件(2j)内部开设的空腔中，绝缘容纳件(2j)的底部开设有通孔，动铁芯(3d)穿过该通孔，并且动铁芯(3d)的底部与导磁材料外壳(2k)固定连接，绝缘容纳件(2j)的两侧分别设置有第一线圈(3u)以及第二线圈(3u)，第一线圈(3u)、第二线圈(3u)以及绝缘容纳件(2j)都设置于导磁材料外壳(2k)内，导磁材料外壳(2k)的顶部至少开设有第一开口以及第二开口，导磁材料外壳(2k)的底部至少开设有第三开口以及第四开口，动铁芯(3d)可以为第一永磁体(3z)以及第二永磁体(3z)提供磁路，第一永磁体(3z)以及第二永磁体(3z)可以在第一线圈(3u)以及第二线圈(3u)的作用下带动绝缘容纳件(2j)沿着动铁芯在导磁材料外壳(2k)内上下运动，绝缘容纳件(2j)可以为第一永磁体(3z)以及第二永磁体(3z)提供缓冲，防止第一永磁体(3z)以及第二永磁体(3z)发生破碎或者失磁。
该继电器的驱动机构上不设置线圈，除此之外该继电器的驱动机构以及驱动机构与电磁机构的装配关系与上述图3a至图3c所对应的实施例类似，此处不再赘述。
本申请实施例提供的该电磁机构，不需要由线圈运动，从而避免了线圈上的铜线发生折断的情况，因此大幅度提高了机构的可靠性。
本申请实施例还提供了一种配电盒，该配电盒用于设置本申请实施例所描述的继电器，请参阅图28，该配电盒包括结构件(X)、驱动板(Z)、功率板(Y)、输入电源连接器(A)、输入电压连接器(B)以及输入电压连接器(C)，这其中，继电器可以固定安装于结构件(X)，驱动板(Z)用于向继电器中的线圈(u)提供电源，通过改变线圈(u)中电流的方向，从而可以实现继电器在分闸位以及合闸位的切换，功率板(Y)与继电器的主回路进行连接，输入电源连接器(A)用于向继电器提供输入电源，输入电压连接器(C)用于向继电器提供输入电压。
