[1] 本发明涉及计吋***领域, 更具体地说, 涉及一种多功能计吋器。
背景技术
[2] 传统的机械钟表的秒表机构为 60秒计吋机构, 对于某些特殊的秒计吋需求, 如 需要进行 30秒、 45秒、 90秒、 120秒、 150秒、 180秒等计吋, 釆用现有的 60秒计 吋机构很不方便。 由于这些特殊秒计吋需求的计吋终点位置在现有 60秒计吋机 构的钟表盘上处于中间位置或秒针需要旋转一周以上才能完成计吋, 而非秒针 从起始位置旋转一周左右完成计吋, 使得使用者阅读计吋结果困难, 对需要旋 转一周以上才能完成计吋的情况, 甚至会由于记错秒针的旋转圏数, 造成阅读 计吋结果错误。
[3] 传统的机械钟表的累计计吋结构为: 计秒累加器指针运行一圏累计 60秒吋, 计 分累加器计 1分钟; 计分累加器运行一圏累计 30分钟, 计分累加器运行两圏吋, 计小吋累加器计一小吋。 由于各种计吋的需求不同, 出现了 25分钟、 45分钟、 6 0分钟等 1小吋内的计吋要求, 传统的机械钟表的计分累加器的刻度范围只能指 示 30分钟, 已不能很好地满足用户的计吋需求。
[4] 传统的机械钟表釆用 12小吋制, 手表显示面一周设置 12小吋, 吋针旋转两周, 完成一天 24小吋显示。 传统的机械钟表的这种指示结构需要使用者参照环境的 吋间变化 (如白天与黑夜的变化、 早与晚的变化等) 来判断手表指示的吋间是 午前吋间还是午后吋间。 但是, 对于缺乏吋间变化参照的工作环境 (如太空飞 船、 潜艇等工作环境) 和一些需要 24小吋计吋的工作场合, 传统的机械钟表的 这种指示结构使用非常不便。 为了解决这一问题, 出现了 24小吋制指示的手表 , 手表显示面一周设置 24小吋, 吋针旋转周, 完成一天 24小吋显示。 但这种 24 小吋指示结构的手表打破了人们已经习惯的手表指示位置的布局, 不符合人们 对钟表早已习以为常的吋间显示位置的思维惯性, 容易引起误读。
发明内容 [5] 本发明要解决的技术问题在于, 提供一种多功能计吋器, 实现秒针旋转一周完 成特殊的秒计吋需求, 满足各种不同的计吋需求, 且在不改变传统的 12小吋制 结构的情况下实现 24小吋制指示, 解决现有技术存在的上述缺陷。

[35] 具体实施方式
[36] 实施例一:
[37] 如图 1所示, 是本发明实施例一的剖面图, 本实施例的多功能计吋器包括累积 秒表转动机构、 计分累加机构和 24小吋制指示机构。
[38] 累积秒表转动机构包括计秒过轮装置、 转动支承在机芯底板 1和夹板 3之间的计 秒传动轮轴 2, 计秒传动轮轴 2靠近夹板端设置有计秒传动轮 22, 计秒传动轮轴 2 下端设置有传动齿轮 21。 计秒过轮装置包括固定连接在夹板 3下侧的第二夹板 4 和过轮组, 过轮组包括与计秒传动轮 22啮合的第一齿轮 5和与计吋秒轮 23啮合的 第二齿轮 8, 第一齿轮 5键连接或固定在第一轴 6上, 第二齿轮 8安装在第二轴上 , 第一轴 6转动支承在第二夹板 4和夹板 3之间, 第一齿轮 5和第二齿轮 8之间通过 一级齿轮或二级齿轮进行连接, 计秒传动轮 22至与秒针固定连接的计吋秒轮 23 之间的分传动比等于秒针旋转一周所等于的预定计吋秒数 A比 60秒。
[39] 计分累加机构包括连接有簧片 111的计吋秒轮 23、 相互啮合的计分过轮 12和计 吋分轮 13, 簧片 111的折弯头部与计分过轮 12的轮齿配合, 簧片 111在计吋秒轮 2 3的带动下驱动计分过轮 12, 计吋分轮 13的齿数等于该计分累加机构的累计分钟 数并大于或小于 30。
[40] 24小吋制指示机构包括 12小吋制吋、 分、 秒传动***, 该传动***包括每 24小 吋旋转一周的拨齿轮 34、 与拨齿轮 34啮合且齿数为偶数的 24小吋制吋间变化参 照轮 33, 拨齿轮 34包括相隔 180度的两个轮齿 44, 参照轮 33的显示表面包括两种 吋间变化参照标志 (图 1中未示出) , 两种吋间变化参照标志 (图 1中未示出) 对应于参照轮 33的轮齿在显示表面上连续交替设置。
[41] 以下分别对累积秒表转动机构、 计分累加机构和 24小吋制指示机构进行阐述:
[42] 一、 累积秒表转动机构
[43] 如图 2所示, 是本发明实施例一中累积秒表转动机构的剖面图, 本实施例中累 计秒表传动机构包括机芯底板 1、 计秒传动轮轴 2、 夹板 3, 计秒传动轮轴 2转动 支承在机芯底板 1和夹板 3之间, 计秒传动轮轴 2在靠近所述夹板 3—端设置有计 秒传动轮 22, 下端设置有受机芯传动装置驱动的传动齿轮 21。
[44] 在夹板 3下侧设置计秒过轮装置, 该计秒过轮装置包括通过定位销 41和连接螺 钉 42固定连接在夹板 3下侧的第二夹板 4和过轮组, 过轮组包括与计秒传动轮 22 啮合的第一齿轮 5、 与计吋秒轮 23啮合的第二齿轮 8和与第二齿轮 8啮合的第三齿 轮 7, 第一齿轮 5和第三齿轮 7键连接 (或固定连接) 在第一轴 6上, 第二齿轮 8轴 向定位并转动连接在计秒传动轮轴 2上, 该第一轴 6转动支承在第二夹板 4和夹板 3之间。
[45] 为了实现秒针旋转一周完成 30秒、 45秒、 90秒、 120秒、 150秒、 180秒等预定 的计吋秒数的需求, 计秒传动轮 22至计吋秒轮 23之间的分传动比应当使机芯传 动装置经传动齿轮 21、 计秒传动轮 22、 过轮组到计吋秒轮 23的传动链的总传动 比满足秒针旋转一周等于预定计吋秒数。
[46] 如原机芯传动装置经传动齿轮 21、 计秒传动轮 22到计吋秒轮 23的传动链的总传 动比为 II, 对应于秒针旋转一周等于 60秒。 增加过轮组后, 计秒传动轮 22经过轮 组至计吋秒轮 23之间的分传动比为 i, 此吋机芯传动装置经传动齿轮 21、 计秒传 动轮 22、 过轮组到计吋秒轮 23的传动链的总传动比为 12, 对应于秒针旋转一周等 于预定计吋秒数 A, 且 I2=Ilxi, 由于传动比与秒针旋转一周等于的预定计吋秒数 成正比关系, 故 I2/Il=i=A/60。 因此, 计秒传动轮 22经过轮组至计吋秒轮 23之间 的分传动比为 i满足大小等于秒针旋转一周等于的预定计吋秒数 A比 60秒。
[47] 在其他实施例中, 第二夹板 4与夹板 3的定位连接关系可以釆用在装配吋釆用专 用设备将第二夹板 4与夹板 3定位配合后固定连接, 而不釆用定位销 41和连接螺 钉 42, 如在一次性机芯结构中, 即可釆用这种连接方式, 以简化结构。
[48] 二、 计分累加机构
[49] 如图 3所示, 图 3是本发明实施例一中计分累加机构的结构示意图, 本实施例中 计分累加机构包括连接有簧片 111的计吋秒轮 23、 相互啮合的计分过轮 12和计吋 分轮 13。 簧片 111的折弯头部与计分过轮 12的轮齿配合, 在计吋秒轮 23的带动下 , 簧片 111拨动计分过轮 12转动, 计分过轮 12驱动计吋分轮 13转动, 进行分钟累 计。 簧片 111拨动计分过轮 12转动一齿, 计分过轮 12驱动计吋分轮 13转动一齿, 计分累加机构累计 1分钟, 因此计吋分轮 13的齿数等于计分累加机构的累计分钟 数, 如计分累加机构需要累计 25分钟、 45分钟、 60分钟等, 计吋分轮 13的齿数 相应取 25齿、 45齿、 60齿, 计吋分轮 13旋转一周, 实现累计预定的 25分钟、 45 分钟、 60分钟的分钟数。
[50] 本实施例的计分累加机构中, 计分过轮 12起传递转动运动的作用, 因此对计分 过轮 12的齿数没有严格要求。 但是, 为了便于计分过轮 12的制造和计分累加机 构的布局设计, 计分过轮 12的齿数与计吋分轮 13的齿数可以按一定的对应关系 选取。 簧片角 a与计分过轮 12的齿数也按照按一定的对应关系选取。
[51] 表 1给出计分过轮 12的齿数、 计吋分轮 13的齿数与簧片角 a的几组对应数值关系
[52] 表 1: 计吋分轮 13齿数、 计分过轮 12齿数及簧片角 α的对应关系

[53] 根据需要, 计分累加机构的指示装置可以釆用多种结构, 以下列举几种, 但该 计分累加机构的指示装置结构不限于所列举的例子。
[54] 1、 计分累加机构指示装置包括显示面和分钟指示指针, 显示面沿圆周标示分 钟数, 最大的分钟数为该计分累加机构的累计分钟数; 分钟指示指针固定连接 在计吋分轮 13的转轴 31上。 指针指示便于使用者读出累计的分钟数。
[55] 2、 指示装置包括显示面和位于该显示面下侧的指示板, 显示面包括显示窗, 指示板固定连接在计吋分轮 13的转轴 31上, 并在该转轴 31至显示窗的距离为半 径的指示板上表面圆周上设置分钟数, 最大的分钟数为该计分累加机构的累计 分钟数, 该分钟数从显示窗显示出来。 指示板数字显示直观地显示出累计分钟 数。
[56] 3、 指示装置包括显示面和位于该显示面下侧的指示板, 显示面包括显示窗, 指示板固定连接在计吋分轮 13的转轴 31上, 并在该转轴 31至显示窗的距离为半 径的指示板上表面圆周上设置显示吋间区段的色块, 该吋间区段从显示窗显示 出来。 指示板色块显示便于提醒大致的吋间区段, 简捷醒目。
[57] 三、 24小吋制指示机构
[58] 如图 6、 图 7所示, 是本发明实施例一中 24小吋制指示机构的示意图, 本实施例 中 24小吋制指示机构包括现有的 12小吋制吋、 分、 秒传动***, 并在传统的日 历机构基础上改进而成。
[59] 如附图 4、 图 5所示, 是传统的日历机构的示意图, 传统的日历机构是通过拨日 轮 52与带内齿轮的日历环 51啮合, 拨日轮 52在其 360度的圆周上只设置一个轮齿 61, 拨日轮 52受机芯传动***驱动每天旋转一周, 通过其轮齿 61与日历环 51的 轮齿 62 (共 31个齿) 配合, 使日历环 51每天转动一个轮齿对应的角度, 日历环 5 1的显示面上对应于轮齿 62标示日历 71, 这样, 在拨日轮的驱动下, 日历环 51每 日转动一个显示位地将日历 71逐日显示出来。
[60] 结合附图 6、 图 7所示, 在传统的日历机构基础上, 将拨日轮 52在其圆周上按照 180度间隔设置两个轮齿 44进行改进形成拨齿轮 34, 将日历环 51的齿数调整为偶 数 (如 20齿、 30齿、 40齿、 50齿等) , 在日历环 51的显示面上将日历 71对应与 其轮齿改变为连续交替设置的吋间变化参照标志 31形成 24小吋制吋间变化的参 照轮 33, 吋间变化参照标志 31以 AM、 PM或上午、 下午等表示。 这样, 拨齿轮 3 4受机芯传动***驱动每天旋转一周, 通过其两个轮齿 44与参照轮 33的轮齿 32的 配合, 每日在 AM12:00和 PM12:00吋各拨动参照轮 33—次, 参照轮 33分别转动一 次, 对应显示" AM"、 "PM"或"上午"、 "下午", 帮助使用者识别手表显示吋间是 午前吋间还是午后吋间。
[61] 因参照轮 33只需要对应交替显示午前和午后标志, 所以参照轮 33的轮齿 32不需 要特定, 只需要取适当的偶数齿 (如 20齿、 30齿、 40齿、 50齿等) , 参照轮 33 的齿形和齿轮尺寸适应拨日轮。
[62] 同吋, 为了表示日、 夜的变化, 将拨齿轮 34在机芯上的安装位置转动 90度在与 参照轮 33进行配合安装, 同吋将参照轮 33显示面上的吋间变化参照标志 31设置 为"白天"、 "黑夜"或太阳图案、 星星月亮图案等, 这样, 参照轮 33在拨齿轮 34的 驱动下, 在每日的 AM6:00和 PM6:00各转动一次, 对应显示"白天"、 "黑夜 "或太 阳图案、 星星月亮图案, 帮助使用者识别是白天还是晚上。
[63] 以上参照轮 33均釆用内齿轮传动结构, 参照轮 33也可以釆用外齿轮与拨齿轮 34 啮合配合, 实现本发明目的。
[64] 本发明的多功能计吋器釆用上述 24小吋制指示机构, 在其显示面上, 对应于吋 间变化参照标志 31设置显示窗, 这样, 参照轮 33的每一次转动就依次将吋间变 化参照标志 31在显示窗中显示出来。
[65] 实施例二:
