Description

一种定时启动的动偶结构 技术领域
本发明涉及一种定时启动结构；特别是涉及一种手表定时启动的动偶结构。
背景技术
随着市场需求日益增长，手表的定义不再仅仅是记录和显示时间的工具，更多的时候手表已经成为消费者价值追求和个性体现的一种标签。功能依旧，但表现方式却层出不穷，动偶类就是其中非常重要的一个组成部分。以模仿动物动作的主题最为常见，且多以问表形式出现，配合响闹报时，音锤敲击音簧的节奏动物们做出相应的设计动作，虽步调一致，但动作僵硬，整体结构复杂，制造和装配工艺都相当复杂。而近两年动物动偶的研发趋势则是向结构简单、可靠，动作栩栩如生的发展。“小丑”的成功就是其中最为成功的一个典型。“小丑”表由俄罗斯独立制表人切金制作，初上市风头无二，订单不断，其后“小丑”的不同版本相继面世，除迎合时事的搭配元素外，也适时增加比以往更多的可动元素，比如德古拉版，其在六点位随时间伸出和收缩的尖牙。
如图1所示，轨道轮片上铣有椭圆形轨道，置于时轮上，并与时轮压合为一体，可动牙齿部件上突出的位钉置于轨道内，当时轮顺时针转动时，轨道轮片上的轨道直接作用于牙齿部件上的突起位钉，使牙齿部件随时轮的转动而上下移动，由于时轮转动一圈需要12个小时，根据轨道外形，牙齿部件从无到有，再从有到无的过程则需要6个小时。现有玩偶手表根据表现主题，一般是从十点开始，牙齿缓慢露出，凌晨一点时牙齿露出最大，其后牙齿开始向回缓慢收缩，到凌晨四点时，牙齿全部隐没。虽然题材动作方式搭配契合，但是动作的一些细节却很难做到惟妙惟肖，比如牙齿伸出动作的表现，3个小时内牙齿需要从无到露出最大，如果不在一段时间内持续关注的话，将很难发现牙齿的移动。

具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细说明：
如图2至图9所示，本发明一种定时启动的动偶结构，包括，凸轮部件10、凸轮杆部件20、回位簧30和快动部件40；所述快动部件40穿过凸轮杆部件10通过导柱螺钉42固定在凸轮杆部件20上，快动部件40在凸轮杆部件20上能够自由转动，快动部件40能够随凸轮杆部件20的转动而移动。所述凸轮部件10、凸轮杆部件20和回位簧30设置在两块夹板之间，所述凸轮部件10和凸轮杆部件20能够在两块夹板间以固定轴为圆心自由旋转，回位簧30能够被杆钉压缩和释放。
所述快动部件40包括导柱41、导柱螺钉42、导柱片43、导柱钉44、导柱 钻45和导向钻46；所述导柱41穿过凸轮杆部件20通过导柱螺钉42固定在凸轮杆部件20上，置于固定夹板下；所述导柱41、导柱片43、导柱钉44压合为一体并保持相对静止，所述导柱钻45套装于导柱41上，并置于固定夹板与导柱之间，保证导柱40移动的平稳性及顺滑性；导向钻46套装于导柱钉44上，导柱钻45和导向钻46均能够在夹板轨道内自由转动，所述导柱41的顶端安装有动偶。特别说明，导柱钻45和导向钻46与夹板轨道侧壁均有间隙，以保证移动平稳顺畅；导柱41在凸轮杆部件20上可以随凸轮杆部件的转动而移动，并由导向钻46与夹板轨道共同作用，以确定导柱的运动轨迹。
快动部件40包括两种结构，其一，如图2所示，所述快动部件40包括导柱41、导柱螺钉42和导柱钻45；所述导柱41穿过凸轮杆部件20通过导柱螺钉42固定在凸轮杆部件20上，置于固定夹板下；所述导柱钻45套装于导柱41上，保证导柱41移动的平稳性及顺滑性；所述导柱41的顶端安装有动偶。
其二，如图8所示，凸轮部件10包括凸轮11和换时轮，凸轮11和换时轮通过凸轮中心孔压合在一起，并保持相对静止；所述凸轮杆部件20包括凸轮杆21、杆钉22和拨杆轴套23；所述杆钉22、拨杆轴套23均压在凸轮杆21上，杆钉22和拨杆轴套23与凸轮杆21保持相对静止；所述杆钉22始终与回位簧30接触。
所述凸轮杆21内周形成有第一工作端21a和第二工作端21c，所述第一工作端21a与凸轮11外周面接触；所述第二工作端21c拨动导柱41上移或下移。
实施例：
如图5所示，凸轮部件10由外界能量传入带动凸轮部件10顺时针转动，与此同时凸轮的圆弧11a顶起凸轮杆21的凸起21a，使凸轮杆21顺时针旋转，凸轮杆21上的杆钉22紧贴回位簧30外侧30a，回位簧30被压缩，储存能量。同时，凸轮杆21内周第二工作端21c随顺时针转动拨动快动部件40，快动部件40缓慢向上运动，牙齿属外观零件，由螺钉固定于导柱41顶端，参见图9。
如图6所示，凸轮部件10继续顺时针转动至凸轮外周圆弧尖端11b与凸轮杆21内周第一工作端21a接触时，凸轮杆部件20顺时针转动至极限位置。此时，回位簧30压缩停止，储存的弹性势能最大；而快动部件40在凸轮杆21内周第二工作端21c的推动下向上运动至上端最大位移处。
如图7所示，当凸轮11继续顺时针旋转，使凸轮11的尖端11b划过凸轮杆21内周第一工作端21a处时，回位簧30所储存的最大弹性势能释放，使回位簧30外侧30a拨动凸轮杆部件20的杆钉22，在此作用下，凸轮杆部件20做逆时针转动，并由凸轮杆21的内周第二工作端21c带动快动部件40迅速下移至极限位置。
随着动力源源不断由凸轮部件10传入，此机构将循环完成上述动作过程，而此过程能完美呈现出牙齿(嘴)缓慢上提，然后快速下落，咬合的动作过程。由凸轮部件10传入的能量来源于跨轮，转速与分轮相当，动偶牙齿的缓慢上提耗时1个小时，但牙齿下落咬合的动作可以在瞬间完成。同时凸轮部件10的能量也可以从时轮、三轮、条盒轮处得到，动偶动作所耗的时间可以根据(输入轮到分轮的传动比乘以60分针)得出。通过调整装针位置可以调整咬合动作的提升、迅速下落的启始时间，从而实现动作的定时启动，达到更加逼真的动偶效果。此结构不仅能用于动偶咬合牙齿的动作，还能用于动偶投掷，摆动等动作。同时，此结构不仅适用于手表，还可用于以齿轮传动为主的钟表、摆件、玩具中。
值得指出的是，本发明的保护范围并不局限于上述具体实例方式，根据本发明的基本技术构思，也可用基本相同的结构，可以实现本发明的目的，只要本领域普通技术人员无需经过创造性劳动，即可联想到的实施方式，均属于本发明的保护范围。
