Description

一种微动式手力驱动充电器 技术领域
本发明属于充电设备领域，具体涉及一种微动式手力驱动充电器。
背景技术
个人电子消费品的应用越来越广泛，因此便携式备用电源成为必不可少的便携部件，而目前一般采用便携式一次性或可充电电池作为备用电源。
由于现有的采用电池作为备用电源的方式在室外或缺电环境下不能再次充电，因此市场上也出现了一些便携式人力发电装置作为备用电源，这类发电装置有的采用人体的手臂或足部等肢体的力量对特殊设计的便携式发电装置作功并将机械功转换成电能，这类方式存在能量转换机构复杂、体积和重量大、成本高、影响人的正常生活节奏等缺点，因而难以得到普及；也有些利用压电效应将足部的踩踏力转换成电能或利用热电效应将人体产生的热量产生电能，这类发电装置的电能转换效率和能量强度都很低，也难以适应个人电子消费品越来越高的功率要求；也有些便携式发电装置利用太阳能电池作为电源，但这类装置仍然存在体积大、成本高、单位体积对应的发电功率密度小、使用条件苛刻等缺点，也不能满足市场的要求。
因此，需要开发一种利用人体生物能、电能转换效率和功率密度高、体积和尺寸小、对人体活动干扰小、工作可靠且成本低廉的便携式发电装置作为日益广泛使用的个人电子消费品的备用电源。

本发明实施例参阅图1-7，本实施例公开了一种微动式手力驱动充电器，包括底盘1、叉臂模组2、脉动发电机3、整流模组4、储能电池5、充电插座6、上盖7、照明灯8和护爪9；
所述叉臂模组2、脉动发电机3、整流模组4、储能电池5和照明灯8均嵌设于底盘1中，上盖7覆设于底盘1上方；
所述叉臂模组2连接至脉动发电机3并用于驱动脉动发电机3发电，所述脉动发电机3通过整流模组4连接至储能电池5以实现电能的存储，所述上盖7 上还设有所述的护爪9以实现电子设备的夹持，所述储能电池5连接至充电插座6并用于为照明灯8和电子设备充电。
在本实施例中，所述叉臂模组2包括叉臂轴201、叉臂杆202、叉臂齿弧203、扭簧204和叉臂轴承205，叉臂齿弧203的外缘呈扇形且外缘的齿牙与脉动发电机3的驱动齿轮309啮合，叉臂杆202和叉臂齿弧203呈交叉角度嵌设于叉臂轴201上，叉臂轴201通过上下设置的叉臂轴承205设于底盘1和上盖7之间，扭簧204套设于叉臂轴201上且扭簧204两端分别锚设于叉臂齿弧203和底盘1上的锚杆扭簧锚杆101上。
在本实施例中，所述脉动发电机3包括电机座301、下轴承302、主轴303、发电机定子304、发电机转子305、卡盘306、上轴承307、单向轴承308和驱动齿轮309，卡盘306嵌设电机座301上端，主轴303的两端分别通过上轴承307和下轴承302设于卡盘306和电机座301的中心，发电机定子304围绕主轴303设于电机座301上，发电机转子305嵌设于主轴303上并覆绕于发电机定子304，驱动齿轮309通过单向轴承308设于主轴303上端，电机座301设于底盘1上，发电机定子304的电压输出线圈通过整流模组4与储能电池5、充电插座6、照明灯8相连。
在本实施例中，所述上盖7的左右两侧分别设有内嵌的指槽701，护爪9分左右两只分别设于上盖7的上部左右两侧，护爪9由滑板91、拉簧92和爪指93组成，滑板91可滑动地设于上盖7本体的滑槽中并且通过拉簧92锚固于上盖7上，爪指93通过铰轴930铰接于上盖7的上表面的上下两端或滑板91的外端。
在本实施例中，所述爪指93包括指板931、嵌入指板931跟部的衔铁933和嵌入在上盖7的表面或滑板91中的磁吸934。
在本实施例中，所述指板931的内侧贴有橡胶材料制作的防滑膜932。
本实施例的工作过程如下：
参阅图1-7，本实施例的典型应用案例如图7所示，使用者只需将上盖7的左、右滑板91拉开并将上下左右四个爪指93展开，然后将个人电子设备(如手机)卡入(爪指93内防滑膜932可以防止手机滑脱)，将手机的充电插座通过电缆与本实施例的充电插座6连接。
使用者手握本充电器的底盘1并将四指和拇指分别扣住左右两侧的指槽701，四指对叉臂杆202的按压驱使叉臂齿弧203克服扭簧204的阻力矩而绕叉臂轴201旋转，进而其通过与其啮合的驱动齿轮309驱使脉动发电机3的主轴303旋转(此时单向轴承308处于锁止状态)并带动发电机转子305旋转并以旋转惯性能的形式暂时保存部分机械能。当叉臂杆202被压到极限位置时，与叉臂齿弧203啮合的驱动齿轮309也停止旋转，而主轴303和发电机转子305由于惯性而继续作正向旋转而不受单向轴承308的约束(此时单向轴承308处于解锁状态)，于是发电机的定子线圈与转子的磁极产生的磁场的耦合而产生脉动感应电势,最后利用整流储电模组的整流电路和储能电池将手指对叉臂杆202按压所蕴含的机械能转换成电压稳定的电能并给个人电子设备充电。而当四指松开时，扭簧204开始驱使叉臂杆202复位做反向旋转，于是与叉臂齿弧203连同与其啮合的驱动齿轮309也做反向旋转，在此过程中，单向轴承308处于解锁状态，所以不会阻碍此时主轴303和发电机转子305由于惯性仍然保持的正向旋转，因此主轴303和发电机转子305储存的旋转惯性能仍然在转换成电能而持续给个人电子设备充电。随着使用者对叉臂杆202的握压与释放，上述过程反复进行，因此本发明能够让使用者可以一边行走而一边能够将其手掌握压产生的机械能转化成电能并给其个人电子设备持续充电。
由技术常识可知，本发明可以通过其它的不脱离其精神实质或必要特征的实施方案来实现。因此，上述公开的实施方案，就各方面而言，都只是举例说明，并不是仅有的。所有在本发明范围内或在等同于本发明的范围内的改变均被本发明包含。
