具体实施方式
为了能够详细了解本发明的技术特征及实用功效，并可依照说明书的内容来实施，更进一步以如附图所示的较佳实施例，详细说明如后，请参阅图1到图5所示的一种端面齿内刹电机，包括有一轮毂10以及组装于该轮毂10内的一定子组20、一转子组30、一磁刹组40及一减速机组50。
如图2所示，该定子组20包括有一电机轴21及套设结合于该电机轴21的发电线圈22，该转子组30连接于该定子组20并可相对该定子组20旋转，该转子组30包括有一包覆于该定子组20的发电线圈22外周的转子罩31。
如图2所示，该磁刹组40连接于该转子组30的转子罩31的一侧，该磁刹组40具有一磁刹座41、一动片42、一手柄43及一定位片44，该磁刹座41是键结并套设于该定子组20之电机轴21上，优选的是，该磁刹座41与该电机轴21由平键固定，使该磁刹座41与该电机轴21在径向不会相对运动，并且位在该转子组30的转子罩31外侧，该动片42位于该磁刹座41与该转子罩31之间，该动片42可选择地对应贴合或分离于该转子组30的转子罩31，于本实施例中，该动片42通过多个复位弹簧的弹性来产生相对该转子罩31活动的动力。
如图3及图4所示，该动片42与该转子罩31之间形成一凹凸交错配置且可相对夹合的刹车结构，于本实施例中，所述的刹车结构分别形成在该转子罩31及该动片42的互为相对的表面上，并且形成多个环绕且间隔配置的凸凹块311、421，各凸凹块311为长条梯形的凸凹块，亦可为三角形、矩形或其他凸起的几何外形，本发明在此不加限制，该动片42是通过刹车结构来将该转子组30的转子罩31刹车。
此外，所述的刹车结构亦可以单独形成在该转子罩31或该动片42一侧，使该动片42或该转子罩31任一侧能够透过凹凸卡制的方式进行摩擦刹车，所述的刹车结构亦不限于凸凹块，也可是凹槽，使该动片42或该转子罩31任一表面相对另一表面凸起，也能达到相同的效果。
如图3至图5所示，于该动片42与该磁刹座41分别设有一个以上的定位栓45、一个以上的止动销46，在本实施例中，该动片42与该磁刹座41之间各设有三个定位栓45及三个止动销46分别等间隔穿设于该动片42并结合于该磁刹座41上，该些定位栓45用于保持该动片42与磁刹座41之间的间隙，各止动销46使该动片42能够固定于磁刹座41而不会产生相对该磁刹座41旋转的圆周运动，各定位栓45与各止动销46亦可优化为单一的台阶螺杆来合并各定位栓45与各止动销46的功能，本发明在此不予限制。
如图3至图5所示，该手柄43及该定位片44是设置在该磁刹座41的另一侧，并于该动片42相对设置，于该手柄及该磁刹座41之间进一步设有一个以上的定位珠47，该手柄43可转动地套设在该磁刹座41，并且可旋动地切换一个设置在该磁刹座41上的转换开关410，透过该手柄43能够切换手动/电动驱动，该磁刹座41环绕设置有一个以上的调节槽411，各调节槽411为呈弧形的凹槽，并且各调节槽411具有一高位及一低位，该手柄43分别对应各调节槽411的位置开设有一个以上的限位孔431，各定位珠47分别对应夹合于所述的限位孔431及所述的调节槽411内，通过扳动该手柄43能够带动各定位珠47于相对应的限位孔431及调节槽411滑动，该磁刹座41进一步于靠近下方凸设有一限位销412，该手柄43对应该限位销412的位置开设有一滑槽432，该手柄43以该滑槽432对应穿设在该限位销412内，同时搭配各定位珠47，使该手柄43相对该磁刹座41作动时能够受到位置的限定。
优选的是，该定位片44系为三角形片体并且覆盖于该手柄43的外侧，该定位片44亦可为四边形或多边形的片体，在此不予限制，该定位片44系分别以三个螺杆441锁设于该磁刹座41，并固定该手柄43于磁刹座41与定位片44之间，透过各螺杆441能够用于承受轴向的拉力，使该手柄43不容易与该磁刹座41分离，该定位片44与该磁刹座41之间有多个复位弹簧，各螺杆441依次穿过该定位片44、各复位弹簧、该磁刹座41后，与该动片42连接。
当该手柄43切换为手动驱动模式时，该手柄43带动各定位珠47由调节槽411的低位朝向高位滑动，此时，该手柄43带动该定位片44、各螺杆441与该动片42沿该电机轴21向外作动，使该动片42与该转子罩31分离，因此该转子组30处于能够自由旋转的状态，使电机呈现手动状态，以便以人力推行车辆行进。
当该手柄43切换为电动驱动模式时，该手柄43带动各定位珠47由调节槽411的高位朝向低位滑动，此时，该手柄43带动该定位片44、各螺杆441与该动片42沿该电机轴21向内作动，使该动片42与该转子罩31相互咬紧卡合，使转子组30处于限制状态，此时无法通过人工方式推行，必须要启动电机，使该磁刹座41内部线圈产生电流作动，才能够使动片42与该转子罩31分离。
如图2所示，该减速机组50系设置于该轮毂10内并相对于该定子组20、该转子组30及该磁刹组40的另一侧，由于该减速机组50为现有结构且非本案重点，在此不加赘述。
本发明的实施方式如图2及图6所示，当本发明的电机运转时，该定子组20、该电机轴21、该磁刹座41、该动片42不会转动，电机工作过程中，动片可以沿着该电机轴21沿轴向朝内或朝外移动，同时，该动片42因该磁刹座41的磁电力作用下，与该磁刹座41吸合，并与各复位弹簧夹合，而与该转子罩31分离，因此，当电机启动运行时，该磁刹座41的内线圈在通电后产生电磁力吸合该动片42，使该动片42的各凸凹块421与该转子罩31的各凸凹块311分离后，解除了刹车状态后，电机开始转动。
如图2、图6及图7所示，当电机断电时，使该磁刹座41的内线圈失去电力时，该动片42将会被各复位弹簧弹出，并且对应抵靠于该转子罩31的侧面，让该动片42能够以刹车结构的凸凹块311、421凹凸卡制以及互相接触摩擦卡合，因此，该动片42在该磁刹座41内的各复位弹簧作用下，向该转子罩31移动并形成使各凸凹块311、421互相咬合，来产生优良的刹车效果，此外，因为该轮毂10内仅需设置有单一的动片42，进而能够简化整体的刹车结构、缩减内部的空间配置及缩小内刹电机的整体体积，使内刹电机又轻巧、又实用。
以上所述，仅是本发明的较佳实施例，并非对本发明作任何形式上的限制，任何所属技术领域普通技术人员，若在不脱离本发明所提技术特征的范围内，利用本发明所揭示技术内容所作出局部更动或修饰的等效实施例，均仍属于本发明技术特征的范围内。
