具体实施方式detailed description
为了更清楚地说明本申请实施方式的技术方案，下面将对实施方式中所需要使用的附图作简单地介绍，应当理解，以下附图仅示出了本公开的某些实施例，因此不应被看作是对范围的限定，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他相关的附图。In order to more clearly illustrate the technical solutions of the embodiments of the present application, the following will briefly introduce the drawings that need to be used in the embodiments. It should be understood that the following drawings only show certain embodiments of the present disclosure, and therefore do not It should be regarded as a limitation of the scope. For those of ordinary skill in the art, other related drawings can be obtained based on these drawings without creative work.
如图4所示，本公开一些实施例提供一种制动器，包括电磁组件、弹簧6、衔铁7、挡板9、摩擦片8及轮毂10。其中，电磁组件包括磁轭1及绕组组件，绕组组件包括：骨架5、线圈11绕制在骨架5上形成的绕组2以及引出线3。挡板9固定设置在与磁轭1具有固定距离的位置，磁轭1及挡板9之间依次设置有弹簧6、衔铁7和摩擦片8。衔铁7和摩擦片8在轴向上不固定，铁芯与衔铁7之间具有间隙。As shown in FIG. 4, some embodiments of the present disclosure provide a brake, which includes an electromagnetic assembly, a spring 6, an armature 7, a baffle 9, a friction plate 8, and a hub 10. The electromagnetic component includes a yoke 1 and a winding component. The winding component includes a skeleton 5, a winding 2 formed by winding a coil 11 on the skeleton 5, and a lead wire 3. The baffle 9 is fixedly arranged at a position with a fixed distance from the yoke 1, and a spring 6, an armature 7 and a friction plate 8 are sequentially arranged between the yoke 1 and the baffle 9. The armature 7 and the friction plate 8 are not fixed in the axial direction, and there is a gap between the iron core and the armature 7.
当制动器的电磁组件不通电时，弹簧6的弹力将衔铁7和摩擦片8紧紧压向挡板9，此时摩擦片8不能径向转动，与摩擦片8间隙配合的轮毂10也处于制动状态；当制动器的电磁组件通电时，定子磁轭1的电磁力克服弹簧6的弹力将衔铁7吸引下来，此时轮毂10可以自由转动，解除制动状态。When the electromagnetic component of the brake is not energized, the elastic force of the spring 6 presses the armature 7 and the friction plate 8 tightly against the baffle 9. At this time, the friction plate 8 cannot rotate radially, and the hub 10 that is in clearance fit with the friction plate 8 is also in control. When the electromagnetic component of the brake is energized, the electromagnetic force of the stator yoke 1 overcomes the elastic force of the spring 6 to attract the armature 7 and the hub 10 can rotate freely at this time to release the brake state.
如图1-2所示，相关技术中的制动器，其引出线3需要在绕组2上绕制到磁轭1的出线孔122处，占用骨架5上的部分绕组2空间，而且相关技术中制动器中磁轭1外环12内径约等于骨架5外径，一般要求引出线3环绕绕组2后不能凸出于骨架5外径，绕组2组件才能与磁轭1正常装配。引出线3较粗且占用了很大的骨架5上的绕线空间，导致骨架5槽满率低，最终导致电磁组件的电磁吸力小，制动器想要达到要求的制动力矩需要做得更大更长，不利于制动器的小型化。As shown in Figure 1-2, the lead wire 3 of the brake in the related art needs to be wound on the winding 2 to the outlet hole 122 of the yoke 1, occupying a part of the winding 2 space on the skeleton 5, and the brake in the related art The inner diameter of the outer ring 12 of the middle yoke 1 is approximately equal to the outer diameter of the skeleton 5, and it is generally required that the lead wire 3 surrounds the winding 2 and cannot protrude from the outer diameter of the skeleton 5 so that the winding 2 components can be normally assembled with the yoke 1. The lead wire 3 is thicker and occupies a lot of winding space on the frame 5, resulting in a low slot full rate of the frame 5, and ultimately resulting in a small electromagnetic attraction force of the electromagnetic component, and the brake needs to be made larger to achieve the required braking torque Longer, not conducive to the miniaturization of the brake.
相关技术中，在骨架5上开槽，绕组2的出线端21与引出线3焊接部或焊接点22处直接卡在骨架5上的槽处；该方法虽然能够使引出线3不在绕组2外圈与骨架5外圈的空隙环绕占用骨架5空间，但是要求骨架5开槽的端面厚度很厚才能保证对线圈的卡紧力。传统骨架5厚度为0.5-1mm，增大厚度会导致制动器长度大大增加，且仅仅依靠过盈配合的卡紧力不能保证引出线3拉拔过程中的可靠性。In the related art, the frame 5 is slotted, and the welding part or welding point 22 of the outlet end 21 of the winding 2 and the lead wire 3 is directly stuck at the slot on the frame 5; this method can make the lead wire 3 not outside the winding 2 The gap between the ring and the outer ring of the frame 5 occupies the space of the frame 5, but the thickness of the slotted end surface of the frame 5 is required to be thick to ensure the clamping force on the coil. The thickness of the traditional skeleton 5 is 0.5-1mm, and increasing the thickness will greatly increase the length of the brake, and only relying on the clamping force of the interference fit cannot guarantee the reliability of the lead wire 3 during the drawing process.
本公开一些实施例提供一种用于制动器的电磁组件，如图5、8-9所示，电磁组件包括骨架5和线圈11。骨架5具有第一挡边51及第二挡边52，第一挡边51与第二挡边52之间形成绕线槽50；线圈11绕制于绕线槽50上形成绕组2，绕组2具有两个出线端21(绕组2端部)。电磁组件还包括引出线3及磁轭1，每个出线端21连接有一个引出线3，且出线端21与引出线3的连接处凸出于骨架5在径向上的外轮廓。在一些实施例中，引出线3与出线端21焊接。引出线3与出线端21采用电烙铁、浸焊或其他焊接工艺进行焊接，保证二者之间焊接牢靠。Some embodiments of the present disclosure provide an electromagnetic assembly for a brake. As shown in FIGS. 5 and 8-9, the electromagnetic assembly includes a skeleton 5 and a coil 11. The skeleton 5 has a first rib 51 and a second rib 52. A winding groove 50 is formed between the first rib 51 and the second rib 52; the coil 11 is wound on the winding groove 50 to form winding 2, winding 2 There are two outlet ends 21 (ends of winding 2). The electromagnetic assembly further includes a lead wire 3 and a magnetic yoke 1. Each lead wire 3 is connected to each lead wire 3, and the connection between the lead wire 21 and the lead wire 3 protrudes from the outer contour of the frame 5 in the radial direction. In some embodiments, the lead wire 3 and the lead end 21 are welded. The lead wire 3 and the lead terminal 21 are welded with an electric soldering iron, dip soldering or other welding processes to ensure a firm welding between the two.
与相关技术不同，如图3所示，在一些实施例磁轭1包括同轴设置的内环11及外环12，内环11与外环12之间形成用于放置绕组2的安装槽13。外环12上设置有引线槽121，出线端21与引出线3的连接处安装于所述引线槽121内，且引出线3通过所述引线槽121引出。在磁轭1上设置引线槽121，因此当电磁组件进行绕组2时，出线端21与引出线3的连接处能够凸出于骨架5径向上外轮廓设置，并且出线端21与引出线3的连接处及引出线3均可以置于引线槽121内，因此引出线3不会过多占用绕组2组件上骨架5的空间，因此充分利用了骨架5的空间进行线圈绕制，提升了槽满率，提高制动器的功率密度。而且上述技术方案在减少甚至避免引出线3占用骨架5空间的同时，不会增大骨架5的厚度，也就不会增大制动器的体积。在提升了绕组2槽满率的同时，输出相同转矩的情况下制动器体积可以大大减小，长度可以大大缩短，大大提高了功率密度。Different from the related art, as shown in FIG. 3, in some embodiments, the yoke 1 includes an inner ring 11 and an outer ring 12 that are coaxially arranged, and a mounting slot 13 for placing the winding 2 is formed between the inner ring 11 and the outer ring 12 . The outer ring 12 is provided with a lead groove 121, the connection point between the outlet end 21 and the lead wire 3 is installed in the lead groove 121, and the lead wire 3 is led out through the lead groove 121. The yoke 1 is provided with a lead groove 121, so when the electromagnetic component is winding 2, the connection between the outlet end 21 and the lead wire 3 can protrude from the radial outer contour of the frame 5, and the lead end 21 and the lead wire 3 Both the connection point and the lead wire 3 can be placed in the lead groove 121, so the lead wire 3 will not occupy too much space on the skeleton 5 of the winding 2 assembly, so the space of the skeleton 5 is fully utilized for coil winding, which improves the slot fullness Rate and increase the power density of the brake. Moreover, the above technical solution does not increase the thickness of the frame 5 and the volume of the brake while reducing or even avoiding the lead wire 3 occupying the space of the frame 5. While increasing the full rate of winding 2 slots, the brake volume can be greatly reduced under the same torque output, the length can be greatly shortened, and the power density is greatly improved.
在一些实施例中，对骨架5的形状不做限定，在一些实施例中的骨架5是圆环开绕线槽50的形式，其他实施例中的四方开槽形也应在本申请的保护范围内。In some embodiments, the shape of the skeleton 5 is not limited. In some embodiments, the skeleton 5 is in the form of a circular loop opening winding groove 50, and the square groove shape in other embodiments should also be protected by this application. Within range.
由于绕组2完成后的骨架5要与磁轭1装配，因此引出线3与出线端21焊接后，裸露的焊点须进行绝缘处理以增加电气可靠性，在一些实施例中在引出线3与出线端21的连接处设置绝缘层12，即可在焊点处缠绕绝缘纸或加装绝缘套管等工艺对焊点进行绝缘处理，增加了电气可靠性。Since the skeleton 5 after the winding 2 is completed needs to be assembled with the yoke 1, the exposed solder joints must be insulated to increase electrical reliability after the lead wire 3 and the lead end 21 are welded. In some embodiments, the lead wire 3 and An insulating layer 12 is provided at the connection of the outlet terminal 21, which can be used to insulate the solder joints by winding insulating paper or installing insulating sleeves at the solder joints, which increases electrical reliability.
如图5-9所示，在一些实施例中，两个出线端21、两个引出线3的位置靠近设置，出线端21与引出线3的两个焊接位置也靠近在一处，引出线3以及其焊接位置均位于引线槽121内，将引出线3从引线槽121的出线孔122穿出后，再将绕组2与磁轭1进行装配。同时，在一些实施例中满足，引线槽121在外环12周向上的长度与引出线3在绕组2组件周向上的分布距离相适配。其中，引出线3在绕组2组件周向上的分布距离即为在一些实施例中两个引出线3之间的距离，使得引出线3能够都安装进 引线槽121内。As shown in Figures 5-9, in some embodiments, the two lead-out ends 21 and the two lead-out lines 3 are located close to each other, and the two welding positions of the lead-out end 21 and the lead-out line 3 are also close to one place. 3 and its welding position are all located in the lead groove 121. After the lead wire 3 is passed out of the lead hole 122 of the lead groove 121, the winding 2 and the yoke 1 are assembled. At the same time, in some embodiments, it is satisfied that the length of the lead groove 121 in the circumferential direction of the outer ring 12 is adapted to the distribution distance of the lead wire 3 in the circumferential direction of the winding 2 assembly. Wherein, the distribution distance of the lead wires 3 in the circumferential direction of the winding 2 assembly is the distance between the two lead wires 3 in some embodiments, so that all the lead wires 3 can be installed in the lead groove 121.
为了使得两根引出线3的电气间隙，两个引出线3之间的距离最好应满足0.2mm，本公开另一些实施例中，磁轭1外环12的周长为L，引线槽121在外环12周向上的长度为W，图8中所示的W此时表示的为引线槽121在外环上的弧线长度，其中，W/L≤0.4，且W≥0.2mm。一般而言，两个引出线3间距越大占用空间越大，对应的磁轭1上的引线槽121开槽的面积越大，而磁轭1开槽越大对制动器吸引力的影响越大，因此引线槽121的尺寸在满足引出线3安装所需外，其最大尺寸根据下述方式设置：本公开一些实施例中，以引线槽121开槽的最大宽度W相比磁轭1外环12周长L的倍数作为变量，试验了不同W/L对制动器性能(在一些实施例中检测的为转矩倍数)的影响，试验结果如图10所示，其结果表明，W/L≤0.4时开槽对制动器输出转矩几乎没有影响，W/L＞0.4时制动器输出转矩下降。因此，W/L要求小于等于0.4；同时为了保证两根引出线3的电气间隙，两根引出线3间距要求大于等于0.2cm，最终引线槽121的尺寸应满足：W/L≤0.4且W≥0.2cm。In order to make the electrical gap between the two lead wires 3, the distance between the two lead wires 3 should preferably meet 0.2mm. In other embodiments of the present disclosure, the circumference of the outer ring 12 of the yoke 1 is L, and the lead groove 121 is in The length of the outer ring 12 in the circumferential direction is W, and W shown in FIG. 8 at this time represents the arc length of the lead groove 121 on the outer ring, where W/L≤0.4 and W≥0.2mm. Generally speaking, the larger the distance between the two lead wires 3, the larger the space occupied, and the larger the slotted area of the lead groove 121 on the corresponding yoke 1, and the larger the slot of the yoke 1, the greater the impact on the brake attractive force. Therefore, the size of the lead groove 121 meets the requirements for the installation of the lead wire 3, and its maximum size is set according to the following method: In some embodiments of the present disclosure, the maximum width W of the lead groove 121 is compared with the outer ring of the yoke 1. The multiple of the 12 circumference L is used as a variable, and the effect of different W/L on the brake performance (in some embodiments is the torque multiple) was tested. The test results are shown in Figure 10, and the results show that W/L≤ Slotting has almost no effect on the brake output torque at 0.4, and the brake output torque decreases when W/L>0.4. Therefore, the W/L requirement is less than or equal to 0.4; at the same time, in order to ensure the electrical gap between the two lead wires 3, the distance between the two lead wires 3 is required to be greater than or equal to 0.2cm, and the final size of the lead groove 121 should meet: W/L≤0.4 and W≥0.2 cm.
本公开对磁轭1上的引线槽121的具体形状不做限定，方形槽、圆形槽、通槽等形式均可，使其满足安装引出线3即可，其他实施例中的能够容纳固化胶固定后的引出线3的焊接位置的其他形状槽均应在本申请的保护范围。如图8所示，在一些实施例中的引线槽121设置为方形槽，引线槽121沿外环12的内壁侧向外环12的外壁侧延伸，且引线槽121在外环12上非贯通，并在外环12的外壁设置有与引线槽121连通的出线孔122，在一些实施例中，设置出线孔122的外环12的外壁同时为引线槽121的侧壁，凸出于骨架5外轮廓的引出线3位置安装至引线槽121内，且引出线3由出线孔122处引出，出线孔122对引出线3可以有一个限位固定作用，再配合固化胶等加固层4，使得引出线3安装更稳固。装配过程中，将绕组2组件的引出线3焊接位置对准磁轭1上的引线槽121，将引出线3出线孔122穿过后，慢慢将绕组2组件推入磁轭1的安装腔腔体，将磁轭1与骨架5绕组2完成装配，如图8所示。The present disclosure does not limit the specific shape of the lead groove 121 on the yoke 1. Square grooves, round grooves, through grooves, etc. can be formed to meet the requirements of installing the lead wire 3. In other embodiments, it can accommodate solidification. The grooves of other shapes at the welding position of the lead wire 3 after the glue is fixed should be within the protection scope of this application. As shown in FIG. 8, in some embodiments, the lead groove 121 is configured as a square groove, the lead groove 121 extends along the inner wall side of the outer ring 12 to the outer wall side of the outer ring 12, and the lead groove 121 does not penetrate through the outer ring 12 The outer wall of the outer ring 12 is provided with an outlet hole 122 communicating with the lead groove 121. In some embodiments, the outer wall of the outer ring 12 with the outlet hole 122 is also the side wall of the lead groove 121 and protrudes from the frame 5. The position of the lead wire 3 of the outer contour is installed in the lead groove 121, and the lead wire 3 is led out from the lead hole 122. The lead hole 122 can have a limiting and fixing effect on the lead wire 3, and then cooperate with the reinforcing layer 4 such as curing glue to make The lead wire 3 is installed more firmly. During the assembly process, align the welding position of the lead wire 3 of the winding 2 component with the lead groove 121 on the yoke 1, pass the lead wire 3 outlet hole 122, and slowly push the winding 2 component into the mounting cavity of the yoke 1. Assemble the yoke 1 and the winding 2 of the skeleton 5, as shown in Figure 8.
在本公开另一个实施例中，如图9所示，引线槽121由外环12的内壁侧向外环12的外壁侧贯通。在一些实施例中引线槽121在外环12上是一个通槽，此时绕组2组件在安装时更方便快捷，凸出于骨架5外轮廓的引出线3引出线3位置对准引线槽121即可，对引出线3的加固效果稍弱，但由于引出线3的焊接位置会设置固化胶等加固层4，因此依然实现了有效固定引出线3。In another embodiment of the present disclosure, as shown in FIG. 9, the lead groove 121 penetrates from the inner wall side of the outer ring 12 to the outer wall side of the outer ring 12. In some embodiments, the lead groove 121 is a through groove on the outer ring 12. At this time, the winding 2 assembly is more convenient and quicker to install. The lead wire 3 protruding from the outer contour of the frame 5 is aligned with the lead groove 121 That is, the reinforcement effect of the lead wire 3 is slightly weak, but since the welding position of the lead wire 3 will be provided with a reinforcement layer 4 such as curing glue, the lead wire 3 is still effectively fixed.
相关技术中由于引出线3与出线端21的焊接位置未被固定，引出线3处于自由 状态，因此绕组2组件在于磁轭1装配过程中或者用户使用过程中，容易对引出线3产生拉拔，使引出线3损坏或脱落。本公开一些实施例中，在引出线3与出线端21的焊接位置处设置加固层4，例如加固化胶进行固定焊接位置，如图6-7所示；加固层4固化后的焊接位置的强度满足引出线3抗拉强度要求；加固层4位于安装槽13内。焊接位置采用固化胶与绕组2固定，固化胶固定后的焊接位置凸出骨架5外轮廓，引线槽121的大小能够容纳胶固定的焊接位置以及加固用的固化胶，保证了绕组2组件能够与磁轭1装配。当然，除了固化胶外的为他加固层4，例如环氧树脂注胶等加固焊接处的方式均应在本申请的保护范围。In the related art, since the welding position of the lead wire 3 and the lead terminal 21 is not fixed, and the lead wire 3 is in a free state, the winding 2 assembly is easy to pull the lead wire 3 during the assembly process of the yoke 1 or the user's use process. , Make the lead wire 3 damaged or fall off. In some embodiments of the present disclosure, a reinforcement layer 4 is provided at the welding position of the lead wire 3 and the lead end 21, for example, curing glue is added to fix the welding position, as shown in Figures 6-7; The strength meets the tensile strength requirements of the lead wire 3; the reinforcement layer 4 is located in the installation slot 13. The welding position is fixed with the winding 2 with curing glue. The welding position after the curing glue is fixed protrudes from the outer contour of the frame 5. The size of the lead groove 121 can accommodate the welding position fixed by the glue and the curing glue for reinforcement, ensuring that the winding 2 components can be connected with The yoke 1 is assembled. Of course, in addition to the curing glue, other reinforcement layers 4, such as epoxy resin injection, etc., to strengthen the weld should be within the protection scope of this application.
采用本公开实施例中的电磁组件结构，在进行在骨架5上绕线圈11形成绕组2时，如图7所示，在骨架5的径向上，绕组2的外轮廓与第一挡边51的边缘或第二挡边52的边缘的距离H小于或等于1mm；在一些实施例中，绕线后的绕组2边缘距离骨架5边缘小于1mm，骨架5绕组2的槽满率接近100％，充分利用了骨架5的空间进行绕线。同时也由于绕组2槽满率非常高，绕线边缘基本与骨架5外轮廓平齐，引出线3与出线端21焊接的位置凸出骨架5外轮廓，在焊接位置加固定胶固定后自然也会凸出于骨架5外轮廓，引线槽121的设置会使得加固化胶的引出线3焊接位置均位于引线槽121内。With the electromagnetic component structure in the embodiment of the present disclosure, when the winding 2 is formed by winding the coil 11 on the skeleton 5, as shown in FIG. 7, in the radial direction of the skeleton 5, the outer contour of the winding 2 and the first rib 51 The distance H between the edge or the edge of the second rib 52 is less than or equal to 1 mm; in some embodiments, the edge of the winding 2 after winding is less than 1 mm from the edge of the frame 5, and the slot full rate of the winding 2 of the frame 5 is close to 100%, which is sufficient The space of the skeleton 5 is used for winding. At the same time, because the winding 2 slot full rate is very high, the winding edge is basically flush with the outer contour of the skeleton 5, and the welding position of the lead wire 3 and the outlet end 21 protrudes from the outer contour of the skeleton 5, and it will naturally be fixed by adding fixing glue at the welding position. It protrudes from the outer contour of the frame 5, and the lead groove 121 is arranged so that the welding positions of the lead wires 3 with cured glue are located in the lead groove 121.
另外，由于绕线后的绕组2的边缘距离骨架5的边缘非常近(小于1mm)，且骨架5的外径略小于磁轭1外环12的内径，所以导电的绕组2与磁轭1的间距非常小，容易引起电气安全的问题。为了解决这一问题，本公开一些实施例中，绕组2组件与磁轭1之间的缝隙设置有绝缘层12。绝缘层12可以在绕组2组件与磁轭1之间涂步绝缘胶、布置绝缘薄膜或灌封环氧树脂，来增大绕组2的爬电距离，保证电气安全。In addition, since the edge of the winding 2 after winding is very close to the edge of the bobbin 5 (less than 1 mm), and the outer diameter of the bobbin 5 is slightly smaller than the inner diameter of the outer ring 12 of the yoke 1, the conductive winding 2 and the yoke 1 The spacing is very small, which can easily cause electrical safety issues. In order to solve this problem, in some embodiments of the present disclosure, the gap between the winding 2 assembly and the yoke 1 is provided with an insulating layer 12. The insulating layer 12 can be coated with insulating glue, insulating film or potting epoxy resin between the winding 2 component and the yoke 1 to increase the creepage distance of the winding 2 and ensure electrical safety.
