Description

自然力控制自行车发电补充蓄电池电量的装置 技术领域
本发明是关于蓄电池领域，特别是涉及一种蓄电池充电的装置。
背景技术
蓄电池适合携带于野外无电源场合。特别是对于骑自行车旅行的车友，在野外宿营时，非常需要有一个能给手提电脑、收音机，较大功率的灯光支持电力的蓄电池。然而，目前只能用通电的方式给蓄电池储存电量。而在野外却没有可以给蓄电池充电的电源。
发明内容
本发明的目的是提供一种在自行车行驶中，利用自行车轮的转动发电给蓄电池充电的装置及方法。
本发明主要技术思路：
为减少人力负载，充电装置最好是在自行车下坡时自动给蓄电池充电。而在上地坡时，充电装置自动与自行车分离。
本发明的具体技术方案：包括自行车及其后架和后轮、蓄电池；其特征在于，还包括：
重力离合装置：其包括安装架及夹子、自锁机构、顶杆和重锤杆；所述安装架通过夹子与自行车的后架固连；自锁机构固定于安装架上；所述顶杆的一端与自锁机构间断性接触，另一端与重锤杆间断性接触；所述重锤杆与安装架上的第二支轴铰接；所述蓄电池设置在夹子上；
驱动装置：其包括摩擦轮、调速器、发电机和支架，摩擦轮与自行车的后轮间断性接触；摩擦轮通过调速器与发电机连接；发电机通过导线与蓄电池连接；其中，所述支架上部与安装架上的第一支轴铰接；支架下部的一部分与调速器固连，支架下部的另一部分与发电机的外壳固连；支架还与自锁机构连接；
上述装置的使用方法：
当自行车进行上坡行驶期间，驱动装置在重力作用下自由垂直，驱动装置的支架与安装架的夹子的夹角大于90°，其摩擦轮与自行车的后轮处于分离状态；
当自行车进行下坡行驶期间，驱动装置在重力作用下绕第一支轴转动，驱动装置的支架与安装架的夹子的夹角小于90°，其摩擦轮与自行车的后轮接触，并被自行车的后轮带动；当自行车的后轮行驶中产生抖动时，与支架连接的自锁机构自动锁住支架，阻止摩擦轮与自行车的后轮分离；转动的摩擦轮驱动调速器，调速器的输出轴驱动发电机转动发电，发电机发出的电通过导线充电于蓄电池；
当自行车进行平地行驶时，重锤杆在重力作用下，绕第二支轴朝后轮的相反方向转动，重锤杆与安装架的夹子的夹角呈直角状，重锤杆的上部推动顶杆，顶杆推动自锁机构，使自 锁机构释放支架，于是支架在重力作用下，绕第一支轴朝后轮的相反方向转动，支架与安装架的夹子的夹角呈直角状，驱动装置的摩擦轮与自行车的后轮分离；发电机停止发电。
本发明与现有技术相比的特点是：
一、在无电源场合，可以用自行车给蓄电池充电。
二、利用重力和自锁机构自动控制给蓄电池充电，以减轻人力负载。即当自行车下坡时，装置与自行车自动结合，给蓄电池充电。当自行车上坡或平地行驶时，装置与自行车自动分离，以减轻人力负载。

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说明：
重力离合装置：(参见图1至图6)该装置主要是根据自行车行驶的状况自动控制是否给蓄电池充电。其包括安装架11及夹子111、自锁机构12、顶杆13和重锤杆14；安装架11通过夹子111与自行车的后架71固连；
自锁机构12固定于安装架11上(参见图6和图7)；该自锁机构包括滑块121、钢球122和弹簧123。图示状态，滑块121只能向左移动。这是由于钢球122将滑块121压紧在楔缝129上，所以滑块121不能向右移动，从而形成了自锁状态。但如果顶杆13的一端将钢球朝弹簧123方向推动，钢球122就不再压紧滑块121，滑块121才可以向右移动。而顶杆13的移动是由重锤杆14控制的。重锤杆14铰接于安装架11上的第二支轴19，重锤杆14上部与顶杆13有间断性接触。
所述蓄电池3设置在夹子111上；
参见图1、图3和图8，驱动装置2包括摩擦轮41、调速器42、发电机43和支架21，摩擦轮41通过调速器42与发电机43连接；需要时，摩擦轮41与自行车的后轮72接触，从 而用自行车的后轮72带动摩擦轮41和发电机43转动。发电机43发出的电通过导线35输入到蓄电池3，给蓄电池3充电。
驱动装置2的支架21上部与安装架11上的第一支轴28铰接(参见图1、图2和图8)；支架21下部的一部分与调速器42固连，支架21下部另一部分与发电机43的外壳44固连；也就是驱动装置2的零部件都安装在支架21上，支架21绕安装架11上的第一支轴28转动，整个驱动装置2也随之转动。
支架21还与自锁机构12连接；这样，自锁机构12就可以通过控制支架21来控制驱动装置2。支架21上设置一滑槽211(见图3)，自锁机构12的滑块121设有一圆销1211，圆销1211位于滑槽211内。当支架21转动时，通过圆销1211带动滑块121移动。或者，滑块121固定时，控制支架21不转动。
上述装置的使用方法：
参见图4、图5，当自行车进行上坡行驶期间，驱动装置2和重锤杆14在重力作用下自由垂直，驱动装置的支架21与安装架的夹子111的夹角大于90°，其摩擦轮41与自行车的后轮72处于分离状态；
参见图6、图7，当自行车进行下坡行驶期间，驱动装置2在重力作用下，绕第一支轴28转动，其支架21与安装架的夹子111的夹角小于90°，其摩擦轮41与自行车的后轮72接触，并被自行车的后轮72带动；当自行车的后轮72行驶中产生抖动时，摩擦轮41就有离开后轮72的倾向。这时候自锁机构12就会阻止摩擦轮41与后轮72分离，也就是支架21通过圆销1211要拨动滑块121向右移动，但由于滑块121被钢球122压紧在楔缝129中，从而锁住支架21不能转动，这样，摩擦轮41继续保持与后轮72接触，被后轮72带动。摩擦轮41通过调速器42驱动发电机43发电，发出的电通过导线35输入到蓄电池3，给蓄电池3充电。
参见图9、图10，当自行车进行平地行驶时，重锤杆14在重力作用下，绕第二支轴19朝后轮72的相反方向转动，重锤杆14与安装架的夹子111的夹角呈直角状，重锤杆14的上部推动顶杆13，顶杆13推动自锁机构12中的钢球122，使自锁机构12中的滑块121不再被压紧，滑块121和支架21一起被释放，于是支架21在重力作用下，绕第一支轴28朝后轮72的相反方向转动，支架21与安装架的夹子111的夹角呈直角状，驱动装置2的摩擦轮41与后轮72分离，这样，发电机43停止发电。
另一实施方法：对于体力好的骑者，在平地行驶时，也可以利用本发明对蓄电池实施充电。方法是在平地上(见图11)，将摩擦轮41调整到与后轮72接触，然后将夹子111固定在后架71上。这样，自行车在下坡和平地行驶时，都可以给蓄电池充电。而在上坡时，摩擦轮41与后轮72是分离的，不再消耗骑者的体力。
