Description

一类实现压页和无障碍翻页的设备 技术领域
本发明属于传动设备设计制造领域，具体涉及一类使用单一动力机实现“解除压点施压状态下的机械锁定-直线上升-正向旋转-反向旋转-直线下降-下压并机械锁定以保持压点施压状态”的高机械耦合机械装置；和另一类实现“解除压点施压状态下的机械锁定-旋转上升-旋转下降-下压并机械锁定以保持压点施压状态”的高机械耦合机械装置。
背景技术
随着科技日益进步，电子书的阅读越来越大众化，电子书具备携带方便、书籍存储量大、翻页方便等优点。但纸质书也有长期存在的必要性。由于版权问题导致很多书籍只有纸质版，人们对于长期使用、需认真阅读的书籍，仍旧偏好纸质书籍；电子书屏幕尺寸较小、字体较小，阅读起来眼睛容易疲劳；尤其是乐器演奏者在面对乐谱演奏时，眼睛相对于乐谱是动态的且距离较远，眼睛更容易疲劳，更加需要纸质的乐谱书。通过调研发现，目前纸质书在学校、乐器演奏等场合，经典阅读或研读等情况下还是主流。总的来说，在未来较长时期内，纸质书阅读仍将是基本的阅读方式。
但纸质书阅读有时需要用手稳定书本，长时间阅读手会比较累。乐器演奏时，乐谱书直立在谱台上,书页失去重力作用需要固定；但现有的各种固定方法又造成了翻页困难，需双手的几个动作才能完成翻页。因此，市场上需要一种具备书页固定功能、翻页更方便的设备。
市场调查结果显示，目前市场上没有针对普通纸质书的这类设备，同时在市场调查中发现，即使手动翻页，只要设备能够自动完成对书页的施压、解除施压状态、避让翻动的书页等机械动作，实现类似书页在没有任何翻页障碍下的自然手动翻页过程，就能获得市场需 求。
考虑到手动翻页过程中，压页和无障碍翻页设备的压点不能对手及书页有干涉，技术方案中对压点的动作要求是：解除压点施压状态下的机械锁定-直线上升-正向旋转90°后停止(此时手和翻动的书页越过压页和无障碍翻页设备某压点的运动范围)-反向旋转90°-直线下降-下压并机械锁定以保持压点施压状态；或者是：解除压点施压状态下的机械锁定-旋转上升90°(此时手和翻动的书页越过压页和无障碍翻页设备某压点的运动范围)-旋转下降-下压并机械锁定以保持压点施压状态。压点的机械响应要快，能够跟随翻页手及时动作。
对于“解除压点施压状态下的机械锁定-直线上升-正向旋转-反向旋转-直线下降-下压并机械锁定以保持压点施压状态”的机械装置，本人发明专利“一种实现升降旋转动作的机械机构”(ZL 2013 1 0490632.6)权利要求1的机械机构，能够满足“直线上升-正向旋转-反向旋转-直线下降-下压”这部分功能要求。
另外通过调研发现，目前存在的机械设备，要实现“直线上升-正向旋转-反向旋转-直线下降-下压”动作，并在断开动力后实现位置锁定及对施压对象压力的保持，都是使用导轨+自锁螺杆+转台+动力机、导轨+非自锁螺杆+转台+动力机+刹车、非螺杆直线传动机构+转台+刹车的方案。这些方案有这些优点：第一，如使用直线导轨进行导向、滚珠丝杠传动、驱动电机带码盘，定位精度很高，机械效率高；第二，由于使用导轨进行导向及承载，负载能力高；第三，由于使用独立的转台实现旋转功能，精度和负载能力高。
技术问题
由于现有机械设备要实现升降旋转两个维度的机械运动，基本上是在平移运动中使用导轨，在旋转运动中使用转台；这降低了设备的动态响应能力、增加了设备的体积、复杂程度和成本，降低了设备的可靠性。
现有设备如果要在无动力状态下保持对施压对象的压力，则会带 来另外一些问题。
如使用非自锁螺杆传动，则有下列缺点：第一，需要添加刹车装置及其控制功能，需要额外的安装空间；第二，刹车装置的刹车状态和解除刹车状态间的相互转换过程，需要几十毫秒或更长时间，不能满足较高的时间响应要求且增加了运行功耗；第三，需要定期维护，以保证稳定性和可靠性；第四，刹车装置增加了设备的复杂程度和成本。
如使用自锁螺杆传动，螺纹升角应小于等于当量摩擦角(螺杆、螺套的螺纹升角小于等于当量摩擦角时，螺套在螺杆上具有轴向自锁性能)，但此时由于螺纹升角较小，螺杆传动效率较低，这提高了对动力机功率的要求，从而导致设备体积、运行功耗和成本的增加。
因此，在要求毫秒级时间响应，传动效率较高，对施压对象施加压力且在无动力情况下能够自锁的应用场合，例如，压页和无障碍翻页设备，就需要研发一些新的机械装置，来满足这些要求。
技术解决方案
为了在同一动力机驱动下实现更快的平移运动时间响应和旋转运动时间响应，进一步提高机构的可靠性和机械效率，在本人完成发明专利“一种实现升降旋转动作的机械机构”(ZL 2013 1 0490632.6)权利要求1机械机构后，继续研发了“全轨道融合体(基座一+相应螺杆机构)”、“轨道+螺套挡圈(基座二+相应螺杆机构)”这两种单一动力机实现升降旋转动作的机械机构。
本发明分别在本人发明专利“一种实现升降旋转动作的机械机构”(ZL 2013 1 0490632.6)权利要求1、“全轨道融合体(基座一+相应螺杆机构)”、“轨道+螺套挡圈(基座二+相应螺杆机构)”机械机构基础上增加压点连接杆、压点、动力机，从而形成了不同的机械装置。实际工程设计中，如果确定了螺套长度和大于当量摩擦角的螺杆、螺套的螺纹升角，可通过逐渐改变压点连接杆横梁长度(压点连接杆横梁长度定义为压点对施压对象施加压力的中心点到螺杆轴线的距离)的方法，得到压点实现螺杆轴向自锁的临界压点连接杆横梁长度， 此时的螺杆、螺套螺纹升角对于特定的螺套长度和压点连接杆横梁长度等参数也是压点螺杆轴向自锁的临界螺纹升角——即综合自锁角；综合自锁角总是大于螺杆、螺套本身的当量摩擦角。在压点对施压对象施加压力且停止对螺杆施加转矩的情况下，当螺杆、螺套的螺纹升角小于等于综合自锁角时，压点对施压对象的压力得到保持，当螺杆、螺套的螺纹升角大于综合自锁角时，增加刹车装置保持压点对施压对象的压力；由此，构成了一类单一动力机实现“解除压点施压状态下的机械锁定-直线上升-正向旋转-反向旋转-直线下降-下压并机械锁定以保持压点施压状态”机械功能的机械装置。
对于“解除压点施压状态下的机械锁定-旋转上升-旋转下降-下压并机械锁定以保持压点施压状态”的机械功能要求，本人研发了由基座、蜗杆、蜗轮、蜗轮轴、压点、压点连接杆和动力机构成的机械装置。
实现上述“解除压点施压状态下的机械锁定-直线上升-正向旋转-反向旋转-直线下降-下压并机械锁定以保持压点施压状态”机械功能和“解除压点施压状态下的机械锁定-旋转上升-旋转下降-下压并机械锁定以保持压点施压状态”机械功能的具体机械装置，均能独立地应用于本申请的压页和无障碍翻页设备，其各自独立的技术特征，分别体现在本申请权利要求2至权利要求5中。以这些具体的机械装置为基础，增加由传感器或图像识别器、驱动器、控制器构成的控制装置，即可构成压页和无障碍翻页的设备。

在螺杆上施加正向转矩时(正向转矩大于解除压点关于螺杆轴向自锁状态所需转矩或已经解除刹车状态)，螺杆推动螺套沿着直导面一上升，当上升到直导面一顶端时，螺套导向台与旋导面一接触，螺杆对螺套产生的围绕螺杆轴线的旋转分力与旋导面一对螺套产生的围绕螺杆轴线的旋转分力同向，形成螺套的旋转力，螺杆对螺套产生的螺杆轴向分力克服旋导面一对螺套产生的螺杆轴向分力,形成螺套的轴向力，在旋转力和轴向力的综合作用下，螺套沿着旋导面一正向旋转上升直到螺套导向台到达旋导面二上端停止；在螺杆上施加反向转矩时，其运动原理与施加正向转矩的运动原理相同，螺杆推动螺套沿着旋导面二反转下降，当脱离旋导面二并接触上直导面二后，沿着直导面二下降，直到压点接触施压对象时，对施压对象施加压力；当停止 对螺杆施加转矩后，若螺杆、螺套的螺纹升角小于等于综合自锁角，压点对施压对象的压力得以保持，若螺杆、螺套的螺纹升角大于综合自锁角，使用刹车装置保持压点对施压对象的压力。

实施例1
如图2所示，是本发明的一种实现压页和无障碍翻页的设备，应用了4个具有“解除压点施压状态下的机械锁定-直线上升-正向旋转-反向旋转-直线下降-下压并机械锁定以保持压点施压状态”功能的机械装置；一号装置30、二号装置31、三号装置32和四号装置33均固定安装在底板34上，书本36放置在底板34和背板35上；一号传感器26、二号传感器27、三号传感器28和四号传感器29均安装在翻页手能有效触发的位置，驱动器、控制器(图中未画出)分别与四个装置上的动力机和传感器连接；常态下四个装置均保持着下压书本36的状态。
如图1所示，一号装置30和二号装置31相同，三号装置32和四号装置33相同；一号装置30和二号装置31与三号装置32和四号装置33的旋转方向相反；一号装置30的压点21称作一号压点、二号装置31的压点21称作二号压点、三号装置32的压点21称作三号压点、四号装置33的压点21称作四号压点，共四个压点；下面详细说 明压页和无障碍翻页设备的一种触发逻辑和压点动作顺序。
如图1显示的是本发明设备的四个压点全部上升到顶，并按设定的旋向旋转90°的状态，方便放置已打开到想要阅读书页的书本36。
如图2所示的是书本36在背板35上面摆放好之后，四个压点均下压到书本36的书页上，将书页压紧在背板35上，此时，四个装置均已准备好配合翻页手的翻页动作。
如图3所示，人面向书，当手从右往左翻页时，翻页手触发了一号传感器26的第一信号状态，一号装置30上的一号压点动作，上升到顶并旋转90°，不再压页从而使翻页动作继续进行。
在继续的翻页过程中翻页手接着触发了一号传感器26的第二信号状态，一号装置30上的一号压点动作，回转90°并下降到书本36上对书页施加压力，变成如图2所示的状态。一号压点动作完成后，二号装置31上的二号压点动作，上升到顶并旋转90°，如图4所示；二号压点动作完成后，三号装置32上的三号压点动作，上升到顶并旋转90°，如图5所示，二号压点、三号压点不再压页从而使翻页手及书页无障碍翻过。
在继续的翻页过程中翻页手接着触发了三号传感器28的第一信号状态，二号装置31上的二号压点动作，回转90°下降到书本36上对书页施加压力，如图6示，此时翻页手在书本36的中线位置。
在继续的翻页过程中翻页手已经到达四号装置33右侧，翻页手触发了四号传感器29的第一信号状态，三号装置32上的三号压点动作，回转90°下降到书本36上对书页施加压力，变成如图2所示的状态。三号压点动作完成后，四号装置33上的四号压点动作，上升到顶并旋转90°，不再压页从而使翻页动作继续进行，如图7所示。
在继续的翻页过程中翻页手已经到达四号装置33左侧，翻页手触发了四号传感器29的第二信号状态，四号装置33上的四号压点动作，回转90°下降到书本36上对书页施加压力，变成如图2所示的状 态，翻页过程完成。
此从右往左翻页过程中使用了一号传感器26、三号传感器28和四号传感器29。
当从左往右翻页时，四个机械装置的动作逻辑与从右往左翻页类似，在此翻页过程中使用了四号传感器29、二号传感器27和一号传感器26。
该压页和无障碍翻页设备的各个机械装置跟随翻页手的动作做出相应的升降旋转动作，以避让书本36被翻动的书页，使翻页动作流畅不中断，并使打开的左右两侧书页的任何一侧书页，在翻页过程中的任何时刻均被至少一个机械装置的压点21压紧在背板35上，翻页和非翻页时书本36及其书页均能保持稳定。
实施例2
如图8、图9所示，是本发明的实现“解除压点施压状态下的机械锁定-直线上升-正向旋转-反向旋转-直线下降-下压并机械锁定以保持压点施压状态”的机械装置一，包括基座一1、螺杆10、螺套11、螺套导向台12、压点连接杆20、压点21、动力机22、主动轮23、传动机构24和从动轮25，动力机22固定安装在基座一1上，主动轮23固定安装在动力机22上，从动轮25固定安装在螺杆10上，主动轮23通过传动机构24与从动轮25连接；其中，螺杆10、螺套11的螺纹升角小于等于综合自锁角时压点21关于螺杆10轴向自锁；基座一1、螺杆10、螺套11和螺套导向台12之间由三个运动副构成运动关系，第一个是连接于基座一1与螺杆10之间的转动副，第二个是连接于螺杆10与螺套11之间的螺旋副，第三个是连接于基座一1与螺套导向台12之间的摩擦副；螺杆10通过转动副安装在基座一1上，螺杆10与螺套11通过螺旋配合安装，螺套导向台12通过摩擦副与基座一1的轨道槽一其中一侧接触，压点连接杆20固定安装在螺套11上。
在螺杆10上施加大于解除压点21关于螺杆10轴向自锁状态所 需转矩的正向转矩，螺杆10推动螺套11沿着轨道槽一的直导面一5上升，当上升到直导面一5顶端时，螺套导向台12与旋导面一8接触，螺杆10对螺套11产生的围绕螺杆10轴线的旋转分力与旋导面一8对螺套11产生的围绕螺杆10轴线的旋转分力同向，形成螺套11的旋转力，螺杆10对螺套11产生的螺杆10轴向分力克服旋导面一8对螺套11产生的螺杆10轴向分力,形成螺套11的轴向力，在旋转力和轴向力的综合作用下，螺套11沿着旋导面一8正向旋转上升，直到螺套导向台12到达旋导面二9上端停止。
在螺杆10上施加反向转矩时，其运动原理与施加正向转矩的运动原理相同，螺杆10推动螺套11沿着旋导面二9反转及下降，当脱离旋导面二9并接触上直导面二6后，沿着直导面二6下降，直到压点21接触书本36时，对书本36施加压力；因螺杆10、螺套11的螺纹升角小于等于综合自锁角，当停止对螺杆10施加转矩后，压点21对书本36的压力得以保持。
实施例3
如图10、图11所示，是本发明的实现“解除压点施压状态下的机械锁定-直线上升-正向旋转-反向旋转-直线下降-下压并机械锁定以保持压点施压状态”的机械装置二，包括基座二2、螺杆10、螺套11、螺套导向台12、螺套挡圈13、压点连接杆20、压点21、动力机22、主动轮23、传动机构24和从动轮25，动力机22固定安装在基座二2上，主动轮23固定安装在动力机22上，从动轮25固定安装在螺杆10上，主动轮23通过传动机构24与从动轮25连接；其中，螺杆10、螺套11的螺纹升角小于等于综合自锁角时压点21关于螺杆10轴向自锁；基座二2、螺杆10、螺套11和螺套导向台12之间由三个运动副构成运动关系，第一个是连接于基座二2与螺杆10之间的转动副，第二个是连接于螺杆10与螺套11之间的螺旋副，第三个是连接于基座二2与螺套导向台12之间的摩擦副；螺杆10通过转动副安装在基 座二2上，螺杆10与螺套11通过螺旋配合安装，螺套导向台12通过摩擦副与基座二2的轨道槽二其中一侧接触，螺套挡圈13固定在螺杆10上，压点连接杆20固定安装在螺套11上。
在螺杆10上施加大于解除压点21关于螺杆10轴向自锁状态所需转矩的正向转矩，螺杆10推动螺套11沿着轨道槽二的直导面一5上升，当上升到直导面一5顶端时解除约束，螺套11同时正转及上升，由于旋导面二9关于螺杆10轴向的长度是根据螺纹升角、螺套11及与螺套11固连相关部件的总质量和综合转动惯量等参数确定的，以使旋导面二9增加螺套11在反向旋转下降过程中的旋转速度，故螺套11在正转且无旋导面增加其旋转速度的情况下，螺套导向台12到达旋导面二9之前，螺套11必先接触螺套挡圈13并与螺杆10结为一体，螺套11和螺杆10在传递给螺杆10的转矩以及等效在螺杆10上的综合旋转动能的作用下一起正转，直到螺套导向台12到达旋导面二9上端停止。
在螺杆10上施加反向转矩时，螺杆10对螺套11产生的围绕螺杆10轴线的旋转分力与旋导面二9对螺套11产生的围绕螺杆10轴线的旋转分力同向，形成螺套11的旋转力，螺杆10对螺套11产生的螺杆10轴向分力克服旋导面二9对螺套11产生的螺杆10轴向分力形成螺套11的轴向力，在旋转力和轴向力的综合作用下，螺套11沿着旋导面二9反向旋转下降；当脱离旋导面二9并接触上直导面二6后，沿着直导面二6下降，直到压点21接触书本36时，对书本36施加压力；因螺杆10、螺套11的螺纹升角小于等于综合自锁角，当停止对螺杆10施加转矩后，压点21对书本36的压力得以保持。
实施例4
如图12、图13所示，是本发明的实现“解除压点施压状态下的机械锁定-直线上升-正向旋转-反向旋转-直线下降-下压并机械锁定以保持压点施压状态”的机械装置三，包括基座三3、螺杆10、螺套 11、螺套挡圈13、螺套回转架14、扭转弹簧15、弹簧柱塞16、压点连接杆20、压点21、动力机22、主动轮23、传动机构24和从动轮25，动力机22固定在基座三3上，主动轮23固定安装在动力机22上，从动轮25固定安装在螺杆10上，主动轮23通过传动机构24与从动轮25连接；其中，螺杆10、螺套11的螺纹升角小于等于综合自锁角时压点21关于螺杆10轴向自锁；基座三3、螺杆10、螺套11、螺套回转架14之间由四个运动副构成运动关系，第一个是连接于基座三3与螺杆10之间的转动副，第二个是连接于螺杆10与螺套11之间的螺旋副，第三个是连接于螺套11与螺套回转架14之间的移动副，第四个是连接于螺杆10与螺套回转架14之间的转动副；螺杆10通过转动副安装在基座三3上，螺杆10与螺套11通过螺旋配合安装，螺套挡圈13固定在螺杆10上，螺套回转架14通过转动副安装在螺杆10上，螺套回转架14又通过移动副与螺套11相连接，扭转弹簧15与螺杆10同轴配合安装，一端固定在基座三3上，另一端与螺套回转架14固定，使螺套回转架14和螺套11在常态下处于平衡位置，弹簧柱塞16固定安装在基座三3上，压点连接杆20固定安装在螺套11上。
在螺杆10上施加大于解除压点21关于螺杆10轴向自锁状态所需转矩并与扭转弹簧15转矩反向的转矩，螺套11以在平衡位置的螺套回转架14为导向上升，在接触到螺套挡圈13时，螺套11和螺杆10结为一体，螺杆10上的驱动转矩克服扭转弹簧15产生的转矩使螺套11正向旋转到位，此时弹簧柱塞16约束螺套11的旋转，当停止对螺杆10施加驱动转矩，并在扭转弹簧15对螺套11产生反向扭矩的情况下，使螺套11保持位置不动。
在螺杆10上施加反向转矩时，由于螺套11的旋转被弹簧柱塞16约束，螺套11沿螺杆10轴向下降一段微小距离，螺套11即脱离弹簧柱塞16的旋转运动约束，在螺杆10和扭转弹簧15同向转矩的共同作用下，螺套回转架14及螺套11反向旋转到平衡位置，螺套11以螺 套回转架14为导向下降，直到压点21接触书本36时，对书本36施加压力；因螺杆10、螺套11的螺纹升角小于等于综合自锁角，当停止对螺杆10施加转矩后，压点21对书本36的压力得以保持。
实施例5
如图14、图15所示，是本发明的实现“解除压点施压状态下的机械锁定-旋转上升-旋转下降-下压并机械锁定以保持压点施压状态”的机械装置，包括基座四4、蜗杆17、蜗轮18、蜗轮轴19、压点连接杆20、压点21和动力机22，动力机22与基座四4固定安装，蜗杆17被动力机22驱动；其中，蜗杆17及蜗轮18的螺纹升角小于等于当量摩擦角，基座四4、蜗杆17、蜗轮18和蜗轮轴19之间由二个运动副构成运动关系，第一个是连接于基座四4与蜗轮轴19之间的转动副，第二个是连接于蜗杆17与蜗轮18之间的蜗轮副；蜗轮轴19通过转动副安装在基座四4上，蜗杆17与蜗轮18通过蜗轮副配合安装，蜗轮18和压点连接杆20均固定安装在蜗轮轴19上。
在蜗杆17上施加大于解除蜗杆17蜗轮18自锁状态所需转矩的正向转矩时，蜗杆17驱动蜗轮18正向旋转并带动压点连接杆20和压点21旋转上升；对蜗杆17施加反向转矩时，蜗杆17驱动蜗轮18反向旋转并带动压点连接杆20和压点21旋转下降，直到压点21接触书本36时，对书本36施加压力；因蜗杆17、蜗轮18的螺纹升角小于等于当量摩擦角，当停止对蜗杆17施加转矩后，压点21对书本36的压力得以保持。
