本申请实施例提供一种旋转驱动器，该旋转驱动器可以应用于沙发或者椅子的头枕部的调节以及腰部支撑的调节，或者应用于床垫硬度调节等。在一种实施例中，请参照图1和图2，该旋转驱动器包括外壳1、驱动件2、连接座3以及传动结构4。其中，外壳1作为整个旋转驱动器的框架，也为旋转驱动器的其它结构提供了安装环境，外壳1的内部具有安装腔13。具体来说，外壳1包括可拆连接的第一半壳11和第二半壳12，两个半壳之间可以通过螺钉固定连接，或者两个半壳之间通过扣接结构扣接，再或者通过卡接结构卡接，具体第一半壳11和第二半壳12之间通过何种方式固定连接，在此不做限定。第一半壳11和第二半壳12用于互相连接的一端均设置有安装腔13，这样第一半壳11和第二半壳12连接时两个安装腔13即可围合形成一个封闭的安装腔13。
驱动件2安装在外壳1上，具体来说，驱动件2安装在第一半壳11背向第二半壳12的一端，且驱动件2的输出端通入安装腔13内，驱动件2通过其输出端输出驱动力。需要说明的是，在本申请实施例中，驱动件2具有输出轴，驱动件2能够绕其输出轴输出转动力，比如驱动件2可以为步进电机。
连接座3与外壳1转动连接，连接座3沿其转轴方向上具有间隔的第一连接端36和第二连接端37，第一连接端36和第二连接端37均用于与外界结构连接，使得外界结构能够绕连接座3的转轴与连接座3同步转动。需要说明的是，连接座3位于安装腔13内，且第一连接端36和第二连接端37分别贯穿第一半壳11和第二半壳12设置，使得连接座3的两端均能够与外界结构连接。值得一提的是，连接座3与驱动件2间隔设置，在本申请实施例中，连接座3整体呈圆柱体设置，连接座3的轴线与其转轴重合，且连接座3的转轴与驱动件2的输出轴平行。
传动结构4设置在安装腔13内，且位于驱动件2与连接座3之间，传动结构4用于连接驱动件2和连接座3，使得驱动件2能够通过传动结构4将其输出的驱动力传递至连接座3，进而驱动连接座3转动。
通过设置传动结构4和转动连接在外壳1上的连接座3，能够将驱动件2的驱动力传递至连接座3上，进而带动连接座3的转动，通过将外界结构与连接座3固定连接，进而能够使得外界结构能够跟随连接座3转动。本申请的旋转驱动器将驱动件2的驱动力转化为连接座3的旋转运动，通过连接座3的旋转带动外界连接结构的运动，相比较于相关技术中线性旋转驱动器的线性运动来说，有利于减小旋转驱动器的整体尺寸，也有利于缩小使用旋转驱动器时所占用的使用空间。
由于第一连接端36和第二连接端37分别贯穿第一半壳11和第二半壳12设置，这样一来，外界结构既可以通过第一连接端36与旋转驱动器连接，也可以通过第二连接端37进行连接。请结合图10，图中所示为旋转驱动器用于调节沙发不同部位的角度，上面一个旋转驱动器是用于调节沙发头枕部的角度，由图可知，此时旋转驱动器通过连接座3位于第二半壳12的一端与头枕部需要活动的部位连接，这样可以实现调节头枕部的角度。位于下方的旋转驱动器用于调节沙发腰部的角度，此时旋转驱动器的第二半壳12通过螺钉与沙发腰部的支架固定连接，旋转驱动器通过连接座3位于第一半壳11的一端与腰部调节结构连接，进而可以调节腰部结构。因此，通过将连接座3贯穿整个外壳1的方式，将旋转驱动器制成可以通过连接座3的两端进行双向连接的结构，能够应用于沙发头枕以及腰部等不同部位的调节，使得旋转驱动器能够调节的部位更加广泛。当然，上述只是例举沙发的两个部位的调节，不代表所有的适用的调节部位。
在一种实施例中，请结合图3和图4，传动结构4包括沿预设方向移动的驱动块41以及转动设置的传动杆42，驱动块41移动时能够带动连接座3转动。在此需要说明的是，本申请实施例中，预设方向为与连接座3的转轴垂直的方向，驱动件2输出的驱动力能够带动传动杆42转动，传动杆42转动时能够驱动驱动块41沿预设方向平移，进而能够带动连接座3转动。
具体地，外壳1内沿驱动块41移动的方向设置有导向件50，导向件50沿着驱动块41的移动方向开设有导槽51，驱动块41在安装腔13内位于连接座3和导向件50之间，且驱动块41的一端能够抵接适配于导槽51内，另外一端用于和连接座3连接，通过设置导向件50和导槽51，能够限定驱动块41的移动方向。值得一提的是，由于外壳1包括第一半壳11和第二半壳12，在设置导向件50时，可以分别在第一半壳11和第二半壳12对应的位置均设置半个导向件50，或者是，在第一半壳11或第二半壳12上设置一整个导向件50，另外一个半壳对应的位置设置让位腔，以便将第一半壳11和第二半壳12连接时给导向件50让位。
在一种具体的实施例中，驱动块41和连接座3之间能够通过齿轮连接的方式进行连接。具体地，驱动块41包括中间部411以及设置在中间部411上的侧边部412，中间部411的外形要与导槽51的外形适配，优选将中间部411设置为圆柱体，导槽51的内壁也设置为与中间部411的外壁贴合适配的弧面。侧边部412朝向连接座3的一端沿驱动块41的移动方向设置有驱动齿4121，连接座3的外壁上对应驱动齿4121的位置凸设有用于与驱动齿4121啮合的外沿齿31。需要注意的是，侧边部412上的驱动齿4121的总长度需要等于或者大于连接座3上的外沿齿31的总长度。通过外沿齿31与驱动齿4121的啮合，在驱动块41移动时，能够带动连接座3转动。值得一提的是，外沿齿31绕连接座3的轴线设置，从其首端绕连接座3的轴线到其尾端之间的角度可以为任意角度，在实际应用中，这个角度优选为120°。
需要说明的是，中间部411上优选设置两个侧边部412，两个侧边部412分别设置在中间部411相对的两端，且两个侧边部412朝向连接座3的一端沿驱动块41移动的方向均设置有驱动齿4121，而连接座3上对应于两排驱动齿4121的位置均设置有与驱动齿4121啮合的外沿齿31。通过设置两排驱动齿4121，能够增加驱动块41与连接座3之间的连接面积，使得两者连接更加稳定，同时也可以使得驱动块41两侧受力更平衡，运动更加平稳，且使得连接座3和驱动块41之间能够承受更大的扭矩。
本实施例中有说到外壳1内设置有导向件50，用以限定驱动块41的移动方向，为了使得驱动块41的移动更加平稳，请结合图9，还可以在第一半壳11或第二半壳12靠近侧边部412的位置设置两个间隔的限位板111，侧边部412靠近限位板111的一端设置抵接板4122，当中间部411贴合适配于导槽51中时，抵接板4122抵接于位于上方的限位板111的底面，侧边部412远离抵接板4122的一面抵接在另外一个限位板111上，进而两个限位板111将一个侧边板夹住，有利于防止驱动块41移动过程中发生转动。当设置两个侧边部412时，一个侧边部412位于第一半壳11内，另外一个位于第二半壳12内，此时可以分别在第一半壳11和第二半壳12内设置两个限位板111限位，或者是只在一个半壳内设置两个限位板111进行限位，另外一个半壳内的侧边部412通过一面抵接导向件50的表面，另外一面抵接半壳内部设置的板筋结构进行限位。
需要说明的是，传动杆42的转轴与驱动块41的移动方向平行，且传动杆42包括沿着驱动块41移动的方向贯穿中间部411且与中间部411螺纹连接的传动部421。传动杆42还包括与传动部421一体成型的从动部422，传动部421和从动部422均为圆柱体结构，且两者的轴线重合，从动部422的外壁上绕其轴线设置有从动齿，驱动件2的输出端上设置有用于和从动齿啮合的涡轮21，通过涡轮21和从动齿的配合，能够带动整个传动杆42转动，进而带动驱动块41移动。需要注意的是，在第一半壳11和第二半壳12上对应于从动部422的位置均设置有至少两个围板14，一个半壳上的两个围板14之间围合形成有与传动部421适配的一半的转动空间，当两个半壳连接时，四个围板14围合形成一整个用于从动部422适配的转动空间，以便整个传动杆42的转动。
在本实施例中，中间部411上沿其移动方向设置有第一定位块60和第二定位块61，其中第二定位块61固定在中间部411靠近从动部422的一端，第一定位块60沿中间部411的移动方向可拆卸连接在中间部411上。第一半壳11内通过螺钉固定有用于控制驱动件2启闭的电路板90，驱动件2与电路板90电连接，电路板90接通电源后，能够通过外部控制器给电路板90发送控制信号，进而控制驱动件2的启闭，同时还可以控制驱动件2驱动连接座3转动的角度。需要说明的是，请结合图5，第一定位块60和第二定位块61位于第一半壳11内，第一半壳11内于第一定位块60、第二定位块61的移动路径上间隔设置有能够分别同第一定位块60、第二定位块61接触的第一行程开关91和第二行程开关92，第一行程开关91和第二行程开关92均与电路板90电连接，且能够单独控制驱动件2的启闭。
需要注意的是，第一定位块60、第二定位块61在第一半壳11内的位置位于第一行程开关91和第二行程开关92之间，第二行程开关92设置在第一半壳11内靠近从动部422的位置，第一行程开关91则沿着驱动块41的移动方向设置在第一半壳11内远离从动部422的位置。值得一提的是，第一行程开关91和第二行程开关92之间的距离需要根据连接座3所需的最大转动角度设置。
通过设置第一行程开关91和第二行程开关92，能够限制连接座3转动所需的最大角度。具体地，连接座3位于初始位置时，第二定位块61与第二行程开关92抵接，此时通过外部控制器给电路板90发送开启驱动件2的信号，可以开启驱动件2带动驱动块41移动，进而带动连接座3转动，同时带动第一定位块60朝向第一行程开关91移动，当连接座3转动至最大角度时，第一定位块60刚好与第一行程开关91接触，进而第一行程开关91控制电路板90关闭驱动件2。当需要将连接座3朝向相反的方向转动最大角度时，通过外部控制器给电路板90发送信号控制驱动件2带动驱动块41朝向相反的方向移动，进而带动连接座3朝向相反的方向转动，当驱动块41移动至第二定位块61与第二行程开关92接触时，电路板90控制驱动件2关闭，此时连接座3刚好转动至最大角度。
在一种更加具体的实施例中，中间部411上设置有定位条413，定位条413具有预设长度，定位条413自中间部411靠近从动部422的一端沿着中间部411的移动方向背向从动部422延伸，定位条413上沿其长度方向设置有多个定位孔4131，这些定位孔4131可以间隔设置，也可以互相连通设置。第二定位块61固设在中间部411上，且位于定位条413靠近从动部422的一端，第一定位块60能够通过螺钉与定位孔4131的连接，可以将第一定位块60固定在中间部411上。需要说明的是，为了在调节连接座3的转动角度时能够调节的角度更加精密，优选将多个定位孔4131连通设置，即多个定位孔4131之间有重合，但是相邻的两个定位孔4131之间重合的部分不能大于螺钉的尺寸，也即螺钉不能从一个定位孔4131移动至另外一个定位孔4131中。
需要说明的是，第一半壳11于第一定位块60和第二定位块61的移动路径上开设有通槽112，通槽112上盖设有用于将通槽112封闭和开启的盖板113。打开盖板113即可通过通槽112露出内部的第一定位块60和第二定位块61，以便改变第一定位块60在中间部411上的位置。
通过设置定位条413，可以改变第一定位块60和第二定位块61之间的距离，进而能够改变连接座3转动的最大角度。具体为，初始位置时第二定位块61接触第二行程开关92，通过改变第一定位块60在定位条413上的位置，可以改变第一定位块60移动至与第一行程开关91接触的距离，这个距离越大，则连接座3能够转动的角度就越大，反之则转动角度越小。因此，第一行程开关91和第二行程开关92之间的距离决定的是连接座3能够转动的绝对角度，而第一定位块60和第二定位块61之间的距离决定了连接座3在第一行程开关91和第二行程开关92限定的绝对最大角度内能够转动的角度，以方便改变旋转驱动器的行程。
在另一种具体的实施例中，请结合图6，驱动块41和连接座3之间还能够通过活动连接的方式进行连接。具体地，连接座3上沿着驱动块41的活动路径贯穿有用于驱动块41通过的活动通道34，驱动块41运动的过程中能够穿过活动通道34。连接座3上还开设有预定长度的连接槽35，本申请实施例中，在连接座3上于第一连接端36和第二连接端37所在的端面均开设有一个连接槽35，连接槽35与活动通道34连通，且两个连接槽35的开设方向以及形状大小均一致。下面仅以位于连接座3上第一连接端36所在的端面开设连接槽35为例进行说明，连接槽35自靠近第一连接端36的位置朝向远离第一连接端36的方向开设。驱动块41上对应两个连接槽35的位置均设置有与连接槽35插接适配的连接柱414，当驱动块41沿预设方向移动时，连接柱414能够在连接槽35中活动。
需要说明的是，当连接座3转动至连接槽35的开设方向与驱动块41的移动方向垂直时，驱动块41与连接槽35正对，且此时连接柱414与连接槽35远离驱动块41的一端刚好抵接或者还未抵接，这样能够防止驱动块41移动过程中出现连接柱414与连接槽35之间卡死的现象，进而通过连接柱414沿着连接槽35的开设路径移动，能够带动连接座3转动。
在一种实施例中，请参照图1，旋转驱动器还包括安装件70，用于将外壳1固定，安装件70能够通过螺钉与外壳1固定连接，根据实际应用场景，安装件70需要通过螺钉安装在第二半壳12上，且安装位置靠近驱动件2的位置。外壳1上于安装安装件70的位置还设置有至少一个用于和安装件70连接的安装柱71，安装件70上对应于安装柱71的位置贯穿有与安装柱71插接适配的穿孔，安装安装件70时首先将安装柱71插接于穿孔中，再利用螺钉固定安装件70。需要说明的是，安装柱71上也可以设置螺纹孔，在某些情况下，可以直接将安装柱71穿插在需要连接的结构上，然后通过螺钉进行固定，图9中所示即为直接通过安装柱71固定连接的情况。
需要说明的是，连接座3沿其转轴贯穿有连接孔32，连接孔32的内壁绕连接座3的轴线凸设有防滑齿33。旋转驱动器还包括连接件80，连接件80具有用于和连接孔32插接适配的连接部81，连接件80还包括与连接部81一体成型的的固定部82。连接部81的外壁上绕其轴线开设有用于和防滑齿33插接适配的防滑槽811，当连接部81插接适配于连接孔32中时，防滑齿33能够插接适配于防滑槽811中，进而阻止连接部81与连接座3之间的相对转动。
值得一提的是，固定部82用于固定外界结构，根据需要固定的结构的不同，固定部82的外形也会不同，比如，请结合图9和图10，比如当需要固定的结构的表面是平面时，固定部82可以为圆盘型，固定时可以先将连接部81贯穿外界连接结构，然后通过螺钉将固定部82固定在外界连接结构上。固定部82还可以是具有圆弧槽的矩形结构，当外界连接结构是需要连接的面是弧面时，可以将外界连接结构的弧面抵接在固定部82的圆弧槽中加以固定。固定部82的结构不做过多的限定，实际应用中需根据实际情况设置。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
