具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
如图1～7所示，为本发明的一个优选实施例。该烛焰片摇曳装置，包括壳体10和设置在壳体10内的烛焰片1、支架2、偏置线圈3、电路板4。
其中，烛焰片1为塑料质构件，烛焰片1的上部设有炬形的火焰片11，火焰片11位于壳体10上端中心的上方，火焰片11向一侧凹入，形成凹片状；烛焰片1的下部设有用于平衡上部重量的配重柱12，配重柱12呈管状，配重柱12底部嵌有永磁体13，永磁体13呈与配重柱12底部相适配的圆柱形；烛焰片1的中部为半圆柱管形的中颈14，烛焰片1的上部与下部通过中部的中颈14而连成一体，中颈14的顶端中心处设有凹入部15，凹入部15的表面为球面；在本实施例中，中颈14、配重柱12位于壳体10上部的内腔中。
支架2为块状塑料质构件，其大致呈T型，包括位于支架2后部的横向部分和从横向部分的中部向前延伸出的竖直部分，所述横向部分与壳体10的内壁连接，所述竖直部分的顶面设有向上凸出的支撑凸缘21，支撑凸缘21活动支撑在烛焰片1的凹入部15中，从而通过支架2将整个烛焰片1可活动地悬挂在壳体10内。在本实施例中，所述支撑凸缘21呈圆锥形，所述支撑凸缘21的顶端为球面形。如此，支撑凸缘21的顶端顶在呈球面的凹入部15内，支撑凸缘21相对中颈14的顶端的摇摆动作更加顺滑、自然，使得烛焰摇摆效果更加逼真。竖直部分的底面还设有向下凸出的呈圆柱形的导限柱22。
所述支架2竖直部分的两侧分别向外侧延伸出有一限位块23，在烛焰片1的凹入部15支撑在支架2的支撑凸缘21之上的状态下，各限位块23的顶面与凹入部15的边缘15a之间存在间隙。该间隙给烛焰片1相对支架2的摇摆提供了活动空间，在烛焰片1相对支架2摇摆过程中，支架2上两侧的限位块23会与凹入部15的边缘15a会发生碰触，此时，烛焰片1相对支架2的竖向中心线(也即，烛焰片1处于复位状态的竖向中心线)摇摆了一定角度，在本实施例中，为35度角，具体请参见图4～7。
如图2和3所示，所述偏置线圈3相对永磁体13偏心设置，所述电路板4与偏置线圈3相电连接。本实施例的烛焰片摇曳装置还包括有设置在壳体底部的电池仓20与开关30，电路板4经开关30与电池仓20相电连接。
工作原理及有益效果：
应用时，电池仓20内装入电池；工作时，电路板4将电池提供的直流电转换为间隔的直流方波脉冲输出，激励偏置线圈3产生间隔的脉冲磁场，脉动偏置的磁场经永磁体13带动烛焰片1发生间歇性的倾斜，由于所述支撑凸缘21对凹入部15的活动支撑，致使烛焰片1产生间歇性、恢复平衡的摇摆运动，使得烛焰片1的所述火焰片11在LED灯的照射下形同摇曳的烛焰。
烛焰片1的所述配重柱12的圆柱台阶管形结构，可使其注塑模具简化抽芯脱模机构，从而降低了生产制造成本；此外，将支撑凸缘21设置在支架2处，将凹入部15设置在烛焰片1处的结构，便于装配，适合于数控智能机械手进行自动化组装，从而避免了需要技能熟练的人工进行装配的弊端，提高了生产效率，降低了综合成本。
本装置结构简单，成本低廉，便于装配，使仿真蜡烛的烛焰片摇曳装置，简化了结构，降低了成本，提高了装配效率，适应于数控智能机械手进行自动化组装，适应于大批量自动化生产的要求。
