本申请提出一种开合结构30，应用于伞100的打开或折叠，伞100包括中棒10、设于中棒10一端的上巢13及可滑动地套设于中棒10另一端的下巢11。需要说明的是这里伞100为电动开收多折伞100。
请参阅图1至图6，在本申请的一实施例中，开合结构30包括设于上巢13内的动滑轮31、拉绳32及设于下巢11的第一定滑轮33，拉绳32的一端设于中棒10的远离上巢13的一端，拉绳32的另一端穿过中棒10，并依次绕过动滑轮31和第一定滑轮33后，固定于上巢13，动滑轮31沿其圆周方向开设有容纳槽311，容纳槽311的两相对槽壁均凸设有若干凸起313，若干凸起313均沿槽壁的周向间隔分布，且两相对槽壁的凸起313呈交叉设置。
具体地，动滑轮31设置于上巢13内，第一定滑轮33设置于下巢11内，拉绳32的一段设置于中棒10的远离上巢13的端部，拉绳32的另一端穿过中棒10，并依此绕过动滑轮31和第一定滑轮33后，固定于上巢13。这里动滑轮31可以正转，也可以反转，动滑轮31转动便可带动拉绳32运动，进而带动下巢11沿着靠近或远离上巢13的方向移动，以打开或折叠伞100。动滑轮31沿着其圆周的方向开设有容纳槽311，这里容纳槽311大致呈环状结构，并且，容纳槽311沿其底壁3113至其开口131的方向呈渐扩设置，即容纳槽311的至少一侧壁3111呈倾斜设置，以使得容纳槽311沿其底壁3113至开口131的方向呈渐扩设置。当然地，这里容纳槽311的形状也可以不为渐扩设置，可以为U型设置，只要拉绳32能够容纳于容纳槽311即可。可以理解的，容纳槽311具有两个相对的侧壁3111，且每一侧壁3 111均呈环形结构，每一槽壁均凸设有若干凸起313，若干凸起313沿槽壁的周向间隔分布，并且两槽壁的凸起313呈交叉设置，这样可以增加拉绳32运动过程中与动滑轮31之间的摩擦力，当拉绳32的两端受力时，拉绳32则会陷入交叉设置的凸起313之间，并呈现弯弯曲曲的蛇状，防止拉绳32打滑，从而提高了多折伞100的使用可靠性。
因此，可以理解的，本申请的技术方案，开合结构30包括设于上巢13内的动滑轮31、拉绳32及设于下巢11的第一定滑轮33，拉绳32的一端设于中棒10的远离上巢13的一端，拉绳32的另一端穿过中棒10，并依次绕过动滑轮31和第一定滑轮33。并且在动滑轮31沿其圆周方向开设容纳槽311，容纳槽311的两相对槽壁均凸设若干凸起313，若干凸起313均沿槽壁的周向间隔分布，且两相对槽壁的凸起313呈交叉设置。这样可以增加拉绳32运动过程中与动滑轮31之间的摩擦力，当拉绳32的两端受力时，拉绳32则会陷入交叉设置的凸起313之间，并呈现弯弯曲曲的蛇状，防止拉绳32打滑现象发生，从而电动开收多折伞100具有较好的使用可靠性。
进一步地，在本申请的一实施例中，容纳槽311的槽壁呈倾斜设置，使得容纳槽311沿其底壁3113至其开口131的方向呈渐扩设置；凸起313的延伸方向与槽壁的倾斜方向一致，且凸起313朝向容纳槽311开口131的端面呈平面设置。
这里容纳槽311的两侧壁3111均呈倾斜设置，便可使得容纳槽311沿其底壁3113至其开口131的方向呈渐扩设置。并且，凸起313的延伸方向与相应槽壁的倾斜方向相一致，这样若干凸起313呈辐射状间隔排列。每一凸起313朝向容纳槽311开口131的端面呈平面设置，这样，当拉绳32一端受力，另一端放松时，拉绳32则会滑出交叉设置的凸起313之间并处于凸起313的端部平面上，由于拉绳32在平面上摩擦力较小，这样可以较为轻松地拉动拉绳32，达到动滑轮31不动时便可手动推开或收回伞100，操作简单且省力。可以理解的，当电池没电电机不转动时，可以实现手开手收的操作。
需要说明的是，这里槽壁的倾斜方向与水平面的夹角的范围为40°～85°，优选为50°～80°，更加优选为60°～70°。在本申请一实施例中，槽壁的倾斜方向与水平面的夹角可为40°、50°、60°、70°、80°、或85°。本申请技术方案中，将槽壁的 倾斜方向与水平面的夹角的范围设置为40°～85°，可使槽壁可对拉绳32起到较佳的限位作用，防止拉绳32在运动的过程中打滑。
在一实施例中，凸起313具有相对的平面端和根端，根端连接于所述容纳槽的底壁；平面端与根部之间的距离范围为0.8mm-1.5mm。也即，凸起313沿容纳槽311的底壁3113至开口的方向的高度为0.8mm、0.9mm、1.0mm、1.2mm或1.5mm。如此的设置，凸起313与槽壁可以有效地对拉绳32起到更好的限位作用，以防止拉绳32在运动过程中出现打滑。
进一步地，相邻交叉设置的两个凸起313的平面端之间的间距大于拉绳32的直径，凸起与相对槽壁之间的距离大于拉绳32的直径。这样的设置，当拉绳32的两端受力时，拉绳32则会较容易地陷入交叉设置的凸起313之间，并呈现弯弯曲曲的蛇状，有效地防止了拉绳32打滑现象发生，从而有效保证电动开收多折伞100具有较好的使用可靠性。
进一步地，凸起313沿容纳槽311的底壁至开口的方向呈渐扩设置。具体地，凸起313的根端与相对的槽壁之间的间距小于平面端与相对槽壁之间的距离，或者是凸起313根端与相邻且交叉设置的凸起的根端之间的距离小于二者平面端之间的距离，如此的设置，当拉绳32生物两端受力时，拉绳32会往动滑轮31的中心轴方向陷入，从而越陷越被拉紧，有效防止拉绳32与动滑轮31打滑。
进一步地，请再次参阅图4，开合结构30还包括第二定滑轮36，第二定滑轮36设于上巢13内，并与第一定滑轮33相对设置，拉绳32的远离伞把15的一端穿过中棒10，并依次绕过动滑轮31、第一定滑轮33及第二定滑轮36后，固定于下巢11。
这里第二定滑轮36和第一定滑轮33一般设置于开合结构30的同一侧，这样拉绳32远离中棒10的一端穿过中棒10，并依次绕过动滑轮31、第一定滑轮33及第二定滑轮36后，固定于下巢11即可。这里设置两个定滑轮和一个动滑轮31，则可使得开合结构30的开合操作更加省力，即伞100的打开或折叠操作更加省力，用户仅需要较小的力便可将伞100打开或闭合。可以理解的，这里动滑轮31一般与电机37传动连接，电机37带动动滑轮31转动，以打开或折叠伞100，由于采用了两个定滑轮，可以使得电机37的驱动力减小，即仅耗费电机37较小的力便可打 开或闭合伞100，这样电机37使用寿命长，工作效率高，耗能较低。
需要说明的是，这里开合结构30还可以包括第三定滑轮，第三定滑轮位于第一定滑轮33和第二定滑轮36之间，这样可以起到导向作用，同时也可进一步使得合结构的开合操作更加省力。
请参阅图5至图8，上巢13的侧壁3111开设有开口131，上巢13的底壁3113开设有与开口131相连通的通孔133，拉绳32的另一端穿过中棒10和通孔133、绕过滑轮、再通过开口131131穿出上巢13、绕过定滑轮后，固定于上巢13。
在本申请一实施例中，请参阅图4，第一定滑轮33固定于下巢11的外表面。上巢13包括外壳，电机37设置有与外壳相适配的齿轮箱381，齿轮箱381的侧表面形成有开口131，且背离电机37的端面开设有通孔133。拉绳32的一端固定于中棒10的远离上巢13的一端，拉绳32的另一端穿过中棒10、通过开口131和通孔133伸入上巢13的外壳内，绕过第一定滑轮33后，再固定于上巢13。这样，下巢11可通过动滑轮31、第一定滑轮33及拉绳32相对于上巢13移动，从而打开或折叠伞100。
进一步地，请参阅图5至图9，开合结构30还包括第一齿轮315、与第一齿轮315相啮合的蜗杆34、及电机37，第一齿轮315套设于滑轮的连接杆314上，电机37与蜗杆34连接。
具体地，第一齿轮315与动滑轮31同轴设置，蜗杆34与第一齿轮315的轴向相垂直设置。
本申请技术方案中，第一齿轮315套设于动滑轮31的连接杆314上，使得第一齿轮315与动滑轮31连接，第一齿轮315与蜗杆34啮合，由于蜗杆34与电机37连接，当电机37驱动蜗杆34正转或反转时，可一并带动滑轮31也正转或反转，进而通过拉绳32和定滑轮带动下巢11沿靠近或远离上巢13的方向移动，从而打开或折叠伞100。
进一步地，请参阅图7、图9及图10，开合结构30还包括第二齿轮35和与电机37连接的变速齿轮组38，变速齿轮组38与第二齿轮35传动连接连接。
这里第二齿轮35与蜗杆34同轴设置。变速齿轮组38可以用来调节第二齿轮35的转动速度，进而调节蜗杆34、第一齿轮315、动滑轮31、第一定滑轮33、第二定 滑轮36、拉绳32及下巢11的运动速度，进而调节开伞100或关伞100的速度。
需要说明的是，变速齿轮组38为多个相互啮合连接的齿轮，变速齿轮组38放置于齿轮箱381内，请参阅图10，变速齿轮组38为相啮合连接的四级变速齿轮，并与第二齿轮35传动连接，使得变速齿轮组38调节第二齿轮35的转动速度。变速齿轮组38与电机37连接，这样使得电机37可通过变速齿轮组38来第二齿轮35的转动速度。可以理解的，这里开合结构30构成了开合结构，用于调节开伞100或关伞100的速度。
本申请还提出一种中棒10，所述中棒10包括上巢13、下巢11、及所述开合结构30。

可以理解的，在需要开伞100时，按下所述开伞按钮511，以触碰所述开伞开关531，进而接通电路，使得所述电机37正转，以带动蜗杆34、第一齿轮315、动滑轮31、第一定滑轮33、第二定滑轮36及拉绳32运动，使得下巢11于中棒10上沿靠近所述上巢13的方向运动，达到开伞100的目的；在需要收伞100时，按下所述收伞按钮513，以触碰所述收伞开关533，进而接通电路，使得电机37反转，以带动蜗杆34、第一齿轮315、动滑轮31、第一定滑轮33、第二定滑轮36及拉绳32运动，使得下巢11于中棒10上沿远离所述上巢13的方向运动，达到收伞100 的目的。
进一步地，控制组件50还包括弹簧式电线56，弹簧式电线56的一端穿过中棒10与电机37连接，弹簧式电线56的另一端与线路板52上的一端子57连接。

本申请的技术方案中，请参阅图2和图3，伞把15包括壳体，壳体内形成有收容空间，收容空间内收容有电路板55和与电路板55电连接的电池59，电路板55的一端形成有输出端口551，线路板52设置有输入端口58，输入端口58与输出端口551电连接。
这里输出端口551一般设置于电路板55靠近按座16的一端，这样可以方便于输出端口551与按座16内线路板52的输入接口58连接。由于电路板55与电池59连接，则可使得电池59为电路板55供电，且通过输出端口551为线路板52供电。
可以理解的，伞把15可通过按座16与中棒10可拆卸地连接，使得在需要对收容空间内的电路板55和电池59进行检修时，只需要拆下该伞把15即可取出该电路板55和电池59，使得应用该伞把15的伞100具有方便检修的优点。另外，当电池59出现充电充不满或者电池不耐用的现象时，可轻易地取出电池59来进行更换。进一步地，由于伞把15可轻易地从中棒10上拆卸出来，使得可于该伞把15内设置电子元件，如：添加设照明、加设蓝牙防丢失、加设MP3等等。以使该伞100具有较多的功能。
进一步地，壳体还开设有连通收容空间的显露孔151，电路板55还形成有充电端口552，充电端口552由所述显露孔151显露，用以为电池充电。这样可方便用户使用。
