请参照图 1和图 5所示， 本发明充电器可换接头结构， 包括快换接插头 5、 移动机构 200、 按键 1、 凹槽形状的导向套 7。 导向套 7可内置于充电器的壳体 内， 其具有一向外的端口。 快换接插头 5相对于导向套 7为拔插件， 它通过导 向套 7的端口内置于导向套 7， 且可在导向套内移动。 接插头 5上设置浮动安 装的弹性浮动键(。 弹性浮动键 C之下安装一弹簧 51， 且通过一开口露出于接 插头 5。 移动机构 200以可滑动的方式安装于导向套 7上， 当快换接插头 5插 入导向套 7时， 移动机构 200与浮动键 C扣合， 以便带动接插头 5滑动。 按键 1设置在导向套 7上， 当移动机构 200通过扣合浮动键 C推动快换接插头 5在 导向套 7中滑动至导向套 7的端口部位时， 揿动按键 1则按键 1与浮动键 C碰 触， 使浮动键 C下压至接插头 5内， 脱离移动机构 200。
本发明的一个优选实施例如图 1 ( a )和图 2所示， 导向套 7上设置固定齿 条 14， 移动机构 200包括推键 2、 齿轮 3和滑移板 4， 滑移板 4上设置活动齿 条 13。推键 2以可滑动的方式安装于导向套 7上，且露出于充电器 900的壳体， 推键 2之下设有齿轮轴 0， 如图 1 ( b ) 的推键底部结构示意图所示， 而齿轮 3 以可转动的方式套接在齿轮轴 D上。 固定齿条 14和活动齿条 13位于齿轮 3两 侧并相互平行， 且分别和齿轮 3啮合。 此外， 滑移板 4上设置套挂孔 45， 当快 换接插头 5插入导向套 7时， 移动机构 200通过套挂孔 45与浮动键 C扣合。
齿轮 3推移动作原理如图 4所示， 同时参考图 5， 由推键 2推动齿轮轴 D 带动齿轮 3径向向前或向后移动， 齿轮 3与固定齿条 14啮合的一侧和被推移 的齿轮轴 D之间产生转动力耦， 齿轮 3上与固定齿条 14啮合一侧的轮齿在固 定齿条 14的轮齿和齿轮轴 D的作用下沿推移方向滚动使齿轮绕齿轮轴 D旋转， 此时因齿轮 3上与活动齿条 13 啮合一侧的轮齿旋转切向力与推移方向相同， 故处于活动状态的活动齿条 13 在其齿条的作用下沿推移方向移动， 当齿轮 3 中心和齿轮轴 D行程为 L1时， 活动齿条 13行程为 L2 = 2L1。 借助活动齿条 13 和滑移板 4，进一步推动通过浮动键 C和套挂孔 45的扣合而套接在滑移板 4上 的快换接插头 5， 快换接插头 5相应向前或向后移动的距离相应地为两倍于推 键 2的移动距离。
如图 5所示，快换接插头 5内设置有可与待充电载体电连接的充电接口 600 以及可导电的内电缘触片 11。充电接口 600可根据不同规格的电子产品设计不 同的适配结构。 内电缘触碰 11 一面露出于接插头 5外部 （例如下表面） ， 另 一面经导线 601与充电接口 600电连接。 导向套 7内设置有可导电的电缘触头 10， 电缘触头 10位于内电缘触片 11 的移动路径上， 电缘触头 10通过外电缘 触片 12与充电装置 900中的电源接线相连接。
在本发明一个优选实施例中， 电缘触头 10设置于导向套 7 内壁上靠近端 口的位置， 而内电缘触片 11在快换接插头 5上的位置满足如下条件： 当快换 接插头 5移动至靠近导向套 7端口时， 快换接插头 5上的内电缘触片 11 随之 滑移到电缘触头 10 的上侧与之弹压接触， 这时充电装置 900 内的电源经可导 电的外电缘触片 12、 内电缘触片 11、 电缘触头 10、 导线 601和充电接口 600 接通， 充电接口 600处于可给待充电载体充电的状态。 当推动推键 2使快换接 插头 5移动至靠近导向套 Ί底部处于收进状态时， 电缘触头 10与内电缘触片 11脱离， 电源断开。
结合参照图 7A〜图 7C和图 8A〜图 8C所示， 并根据需要参照图 1， 图 7A 所示为快换接插头 5位于导向套 7底部， 一对电缘触头 10 (参见图 8A) 与一 对内电缘触片 1 1分离。 如图 7B及图 8B所示， 经推键 2推移后， 快换插接头 5 上的充电接口 600伸出充电装置 900机壳外， 电缘触头 10与内电缘触片 1 1碰 触。 如图 7C及图 8C所示， 按下按键 1， 浮动键 C与套挂孔 45脱离， 快换插接 头 5可拔离导向套 7。
此外， 回到图 5所示， 在本发明的实施例中， 与电缘触头 10 电连接的外 缘接触片 12可用弹性金属材料制成， 与电缘触头 10铆接为一体后， 安装在导 向套 7上。 安装的方式是： 先将电缘触头 10置入导向套 7下壁的通孔内， 使 电缘触头 10上部的锥球面凸出导向套 7的内表面， 再以外缘接触片 12中间部 位与导向套 7热铆安装。 将快换接插头 5置入导向套 7内时， 快换接插头 5的 下表面与电缘触头 10的锥球面接触并将其压下， 使外电缘接触片 12通过电缘 触头 10的位移而产生弹性压力， 该压力可使电缘触头 10与快换插接头 5下表 面间持续接触。 故当快换插接头 5滑移到和滑离伸出一止推位（容后叙述）时， 即电缘触头 10与内电缘触片 11接触时， 电源的通断得到切换。 通过内电缘触 片 11、 电缘触头 10、 外电缘触片 12之间的弹压设置， 使装置在对快换插接头 5进行伸缩滑移操作的同时便实现了充电电源的通断， 即开关功能。
如图 3、图 5和图 7A〜图 7C所示，在导向套 7的端口夕卜，还可设置翻盖 9， 翻盖 9通过弹性元件扭簧弹压而与导向套 7盖合。 当快换接插头 5上的充电接 口 600向导向套 7外伸出时， 原本由扭簧弹压与充电装置 900的机壳盖合的翻 盖 9被推开， 绕其装卡在充电装置 900的机壳上的门轴 92旋转而逐渐翻开， 为快换接插头 5的伸出让位。
如图 1、 图 7B、 图 7C所示， 本发明的一个优选实施例中， 在按键 1 内侧 设置片簧 8， 片簧 8两端固定在导向套 7上， 片簧 8中段卡在按键 1 内侧的一 个槽中。 当快换接插头 5滑移至导向套 7端口部分时， 按压按键 1可使快换接 插头 5上的浮动键 C脱开滑移板 4上的套接孔 45， 充电插接头 5可以取出。 快 换插接头 5脱离导向套 7及充电装置 900的状态如图 6所示。 此外， 欲换上另 一只具有不同充电接口的充电插接头时， 只须以图 6所示的箭头方向， 将新的 充电插接头插入导向套 7 内， 推入， 待浮动键 C弹入滑移板 4上的套挂孔 45 即可完成充电插接头的快换。
再回到图 1所示， 在本发明的优选实施例中， 在导向套 7上对应滑移板 4 的一侧卡装弹定片 6， 弹定片 6上具有弹性突起 61， 滑移板 4上设置与突起 61 形状相同的豁口 B， 突起 61位于豁口 B的运动路径上。 当滑移板 4上的豁口 B 被推移到止推位 A， 且电缘触头 10与内电缘触片 11接触时， 弹定片 6上的突 起 61卡入豁口 B浮动定位， 此时滑移板 4的推移到达伸出止推位八。 工业应用性
本发明将带有充电接口的快换接插头设计成插拔件， 当将本发明所提供的 结构集成于充电装置时， 快换接插头可以插入导向套中与电源连接并为相应的 待充电载体充电， 当待充电载体充电变换时， 只需更换具有不同充电接口的快 换接插头即可为另一个待充电载体充电， 从而可充当多种充电接口规格的充电 器； 同时通过固定齿条和活动齿条齿轮的配合， 可使快换接插头的在推键推动 下滑移时， 其滑移距离两倍于推键滑移距离， 节省了机构安装空间。 不仅使用 方便， 而且便于减小充电器的体积。
