Description

1. 一种大功率鼠标用的无线充电、储电组件 技术领域
本实用新型涉及一种无线充电装置，具体的说是一种适用于大功率鼠标用的，可实现无线充电、储电的组件。
 背景技术
鼠标无线化是一种极为明显的行业发展趋势，各厂商为迎合该发展趋势，相继推出了各类无线鼠标 ，但目前的无线鼠标均是常规的低功率鼠标，即鼠标的工作功率低，响应性以及精确度均一般，该类无线鼠标不能满足于如制图、游戏等对鼠标要求较高的使用领域当中。事实上，并非行业中无人研制大功率无线鼠标，如无线的游戏鼠标，但该此产品在实际使用过程当中，均存在极为明显的使用缺陷，具体的说，由于目前的无线充电组件只能即时充电，即收集的电流只供使用，而采集电流的稳定性受鼠标与无线送电模块间的相对位置直接影响，而在实际鼠标使用过程当中，并不可能要求使用者在最佳区域内使用，故而经常发生，鼠标响应性延迟、准确度受影响，或是使用者由于使用需要瞬间脱离了无线受电的有效区域，会造成鼠标的无线连接瞬间丢失，而重连鼠标的过程受当前技术所限，往往需要以秒计算，这使用极大的影响了鼠标的实际使用体验，甚至说，一定程度上，此类无线大功率的鼠标对使用者有了更大的束缚，并不能满足实际使用的需要。
 技术问题
基于上述原因，大功率无线鼠标受技术影响，一直未能得到有效的应用推广，是各家鼠标厂商亟待解决的技术难题。
 技术解决方案
本实用新型的目的在于克服现有技术所存在的不足，提供一种能满足实际使用需要的大功率鼠标用的无线主电、储电组件。
为实现上述目的，本实用新型所采用的技术方案是：一种大功率鼠标用的无线充、储电组件，包括无线送电模块、受储电模块，无线送电模块包括MCU、交流升压IC、共振电路、监测单元；MCU振荡讯号给交流升压IC，交流升压IC带动共振电路产生感应电磁场；监测单元与MCU的引脚相接，用于监测区域内是否存在受储电模块；监测单元是震动感应开关与红外线发射接收器中的一种或组合；受储电模块包括受电共振电路、桥式整流电路、稳压IC、多个滤波电容、法拉电容、齐纳二极管、萧特基二极管、升压稳压IC以及电感；受电共振电路与桥式整流电路相连；桥式整流电路与齐纳二极管连接；齐纳二极管经多个滤波电容后，一路经稳压IC以及一个萧特基二极管与法拉电容相接，另一路经电感、升压稳压IC以及一电容后输出；法拉电容经一萧特基二极管后与电感相接。
 有益效果
本实用新型结构简单，设计合理，利用法拉电容实现受电后的电能存储，经由法拉电容储电后主动输出可实现大功率无线鼠标在非受电区域时一定时长内的正常使用，对于大功率无线鼠标特别是无线游戏鼠标的发展有着极大的应用价值。
 附图说明
图1是无线送电模块的电路示意图。
图2是受储电模块的电路示意图。
 本发明的最佳实施方式
为方便对本实用新型作进一步的理解，现结合附图举出实施例，对本实用新型作进一步的说明。
实施例：
如图1、2所示，本实用新型包括无线送电模块、受储电模块，无线送电模块包括MCU、交流升压IC、共振电路、监测单元；MCU振荡讯号给交流升压IC，交流升压IC带动共振电路产生感应电磁场；监测单元与MCU的引脚相接，用于监测区域内是否存在受储电模块；监测单元是震动感应开关与红外线发射接收器中的一种或组合；受储电模块包括受电共振电路、桥式整流电路、稳压IC、多个滤波电容、法拉电容、齐纳二极管、萧特基二极管、升压稳压IC以及电感；受电共振电路与桥式整流电路相连；桥式整流电路与齐纳二极管连接；齐纳二极管经多个滤波电容后，一路经稳压IC以及一个萧特基二极管与法拉电容相接，另一路经电感、升压稳压IC以及一电容后输出；法拉电容经一萧特基二极管后与电感相接。
进一步的说，实施时，如图1所示，无线受电模块当中由MCU U1振荡出125KHz的讯号给交流升压IC U2配合L1、C1共振电路产生感应的电磁场,配合传感器如震动感应开关S1可侦测无线电竞鼠标是否有在鼠标垫上使用,当MCU U1 的5脚侦测到无线电竞游戏鼠标在鼠标垫上静止一段时间不动时, MCU U1会进入休眠模式,关闭鼠标垫内的交流升压IC U2和L1、C1共振电路,达到省电的效果。
如图2所示，受电共振电路L1、C1感应电磁场产生交流的电压经D1,D4,D6,D7桥式整流电路将交流电压转换直流电压再经过齐纳二极管D3稳压并配合C3,C2滤掉直流电压上的纹波,经过特定稳压IC U1提供对法拉电容C5额定电压2.7V充电并提供限流，不致将齐纳二极管D3稳压拉下来而造成无法边使用无线鼠边充电,萧特基二极管D5是防止法拉电容C5对U1的特定稳压IC回灌电流, 萧特基二极管D2的功能是阻止齐纳二极管D3稳压高于2.7V电压对法拉电容C5直接充电使法拉电容C5造成损坏,当平常边使用边充电时齐纳二极管D3直流稳压会提供给特定稳压IC U1对法拉电容C 5充电并经电感L2,升压稳压IC U2,电容C4提供稳定的电压给无线电竞鼠使用,达到边使用无线电竞鼠边对无线电竞鼠充电的功能,当无线电竞鼠离开鼠垫使用或使用在加长型的电竞鼠垫上,此时法拉电容C5会提供电源经萧特基二极管D2,电感L2,升压稳压IC U2,电容C4提供稳定的电压给无线电竞鼠使用一段较长的时间。
经由图1、2的示意电路配合工作，达到无线鼠标受电、充电使用的目的。
以上所述，仅是本实用新型的较佳实施例而已，并非对本实用新型作任何形式上的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或修饰为等同变化的等效实施例，但是凡未脱离本实用新型技术方案内容，依据本实用新型的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本实用新型技术方案的范围内。
