上述的节电无线鼠标, 所述充放电电路包括第一电容 Cl、 第一电阻 R1 ; 所述第一电 容、 第一电阻并联后, 一端连接所述可控硅 K的阴极, 另一端接地。
ώ于采用了以上的方案, 带来了如下的有益效果:
本发明增设触发供电电路, 输入模块发出指令时, 触发供电模块内部充电且输出端触 发中央处理单元、 发送模块和发送天线的供电回路导通, 鼠标正常工作; 输入模块未发指 令时, 触发供电模块内部放电, 维持供电回路导通, 以保持鼠标的灵敏度; 触发供电模块 内部放电完成后, 供电回路截止; 此时鼠标不消耗任何能氩因此所消耗的电能大幅降低, 延长电池的使用时间, 用户无须频繁更换电池, 显著降低了用户的使用成本。
本发明触发供电电路中包括充放电电路及开关电路, 当所述输入模块按键动作时,电 源接通,充放电电路同时充电,未按键时充放电电路放电,使开关电路控制极有一定电压, 开关电路仍然导通, 中央处理单元、 发送模块和发送天线等电路仍然正常工作, 若一定时 间后仍然没有点击操作,则放电基本完成时,开关电路截止, 中央处理单元、 发送模块和发 送天线等电路自动关断,如此既可以在鼠标闲置的一定时间内, 保持其响应的高灵敏度, 又可以在鼠标闲置时间较长时, 自动关断各相关电路, 达到省电节能的目的, 可大大节省 了鼠标消耗的能源, 延长电池的使用时间, 用户无须频繁更换电池, 方便用户, 同时显著 降低了用户的使用成本。 例如: 按鼠标点击一次需要 100毫秒,放电过程为 1秒,若用户每 06 001404
10秒点击一次鼠标,则原来只能使用 5天的两节普通电池采用本方案后可以使用 50天, 若 用户每 30秒点击一次鼠标,则原来只能使用 5 天的两节普通电池釆用本方案后可以使用 150天, 电池的使用时间延长了近 30倍。
本发明的方案, 电路结构简单, 成本低, 易实现。
通过改变充放电电路的第一电容和 /或第一电阻的标称值, 控制充电电量和放电时间 的长短, 从而方便地取得省电节能与保持鼠标高灵敏度之间的均衡。

下面通过具体的实施例并结合附图对本发明作进一步详细的描述。
图 1是现有技术的无线鼠标发射装置电路原理框图。
图 2是现有技术的无线鼠标接收装置电路原理框图。
图 3是本发明无线鼠标发射装置的电路原理框图。
图 4是本发明无线鼠标发射装置实施例一的电路原理图。
图 5是本发明无线鼠标发射装置实施例二的电路原理图。
图 6是本发明无线鼠标发射装置实施例三的电路原理图。
具体实施方式 '
如图 3所示,本发明在现有技术鼠标的原有基础上增加了一个触发供电模块 33, 与输 入模块 32和中央处理单元 34、 发送模块 36和发送天线 37等相连,输入模块 32发出指令 时,电源 31接通, 触发供电模块 33触发中央处理单元 34、 发送模块 36和发送天线 37等 同时导通工作; 输入模块 32未发指令时,触发供电模块 33与电源 31断开,电路内部放电, 仍保持正常工作状态, 若一定时间后仍然没有点击操作,则电路放电完成后,整个电路自动 关断。 '
第一实施例: 如图 4所示为本发明无线鼠标发射装置一种实施方式的电路原理图。触 发供电模块 33包括开关电路和充放电电路,开关电路包括第四二极管 D4、第五二极管 D5、 第六二极管 D6、 可控硅 K、 第二电阻 R2、 第三电阻 R3和第一场效应管 Q1第二场效应管 Q2、 第三场效应管 Q3 ; 充放电电路包括第一电容 Cl、 第一电阻 Rl。 第四二极管 D4、 第五 二极管 D5、 第六二极管 D6的正极与输入模块的三个按键分别相连, 第四二极管 D4、 第五 二极管 D5、 第六二极管 D6的负'极并接于第一可控硅 K的控制极, 可控硅 K的阳极接电源 正极, 阴极接于第一电容正极。第二场效应管 Q2的控制极与第一场效应管 Q1的漏极相连, 第二场效应管 Q2的漏极与第三场效应管 Q3的控制极相连。 第一电容 Cl、 第一电阻 R1并 联于第一场效应管 Q1的栅极与源极之间,并共接于地 (即电源负极), 第三场效应管 Q3的 漏极与中央处理单元、 发送模块、 发送天线等电路的低电位相连。 在输出模块输出端与中 央处理单元输入端之间, 增设第一二极管 Dl、 第二二极管 D2第三二极管 D3, 以防止电流 从中央处理单元流向触发供电电路。 当输入模块的按键动作时, 电源接通, 电路工作并给 第一电容 C1充电, 未按键时,因为第一二极管 D1和第二二极管 D2、第三三极管 D3的单向 导通性,不会导致电流通过中央处理单元流向触发供电模块 33, 用户点击某个按键时电流 通过其对应的二极管 (D4、 D5或 D6 ) 流向可控硅 K的控制极, 可控硅 K导通。 因可控硅 K 的阳极所接电源正极, 阴极接充电电路, 此时可控硅 K对第一电容 C1充电, 使第一场效 应管 Q1的栅极有一定电压,第一场效应管 Q1导通,此时第一场效应管 Q1的漏极为低电位, 第二场效应管 Q2截止, 第三场效应管 Q3栅极为高电平, 第三场效应管 Q3导通。 若一定 时间后仍然没有点击操作, 则电容放电基本完成时, 第一场效应管的栅极电压过低, 第一 场效应 Q1管截止, 第二场效应管 Q2导通, 第三场效应管 Q3截止。 整个电路自动关断, 此时不再消耗任何能量, 当用户再次点击后, 电路自动实时接通, 不影响使用。
通过减小第一电容 C1的容量可以在点击时充相对少的电,实现更加省电的目的. ' 通过增大第一电容 C1的容量可以延长其放电的时间,通过增大第一电阻 R1阻值也可 以延长第一电容 C1 的放电时间, 从而, 即使用户长时间不按键也能够保持鼠标响应的高 灵敏性.
开关电路的实现方式并不限于本例所指, 如第一场效应管 Ql、 第二场效应管 Q2、 第 三场效应管 Q3 可以用结型场效应管、 绝缘栅型场效应管或者其它可以实现一定电压控制 其开关的场效应管, 如 3018等。
输入模块 32上可以是两个、 三个或更多的按键, 当按键更多时, 开关电路增加相应 数量的二极管可实现同样的功能。
第二实施例:如图 5所示为本发明的另一种实施方式, 与第一实施例不同的是, 不是 釆用第四二极管 D4、 第五二极管 D5、 第六二极管 D6以防止第一电容 C1对中央处理单元 34放电,而是在输入模块 32 (鼠标按键)上采用联动双刀开关, 当用户没有按键时断开第一 电容 C1与中央处理单元 34的连接, 来防止第一电容 C1对中央处理单元 34放电,这样可 以起到相同效果, 同时降低本发明的实施成本。
本实施例中通过减小第一电容 C1的容量, 可以在鼠标按键点击时充相对少的电, 实 现更加省电的目的。
本实施例中通过增大第一电容 C1的容量可以延长其放电的时间, 通过增大第一电阻 R1阻值也可以延长第一电容 C1 的放电时间, 从而, 即使用户长时间不按键也能够保持鼠 2006/001404 标响应的高灵敏性。
第三实施例: 如图 6所示为本发明无线鼠标发射装置一种实施方式的电路原理图。触 发供电模块 33包括开关电路和充放电电路,幵关电路包括第四二极管 D4、第五二极管 D5、 第六二极管 D6和第一场效应管 Q1 ; 充放电电路包括第一电容 Cl、 第一电阻 Rl。 第四二极 管 D4、 第五二极管 D5、 第六二极管 D6的正极与输入模块的三个按键分别相连, 第四二极 管 D4、 第五二极管 D5、 第六二极管 D6的负极并接于第一场效应管 Q1的栅极, 第一电容 Cl、 第一电阻 R1并联于第一场效应管 Q1的栅极与源极之间,并共接于地 (即电源负极), 第一场效应管 Q1 的漏极与中央处理单元、 发送模块、 发送天线等电路的低电位相连。 在 输出模块输出端与中央处理单元输入端之间, 增设第一二极管 Dl、 第二二极管 D2第三二 极管 D3, 以防止电流从中央处理单元流向触发供电电路。 当输入模块的按键动作时, 电源 接通, 电路工作并给第一电容 C1充电, 未按键时,因为第一二极管 D1和第二二极管 D2、 第三三极管 D3的单向导通性,不会导致电流通过中央处理单元流向触发供电模块 33,又由 于第三二极管 D3和第四二极管 D4的单向导通性, 第一电容 C1不会对中央处理单元 34放 电, 而只对第一电阻 R1放电, 使第一场效应管 Q1的栅极有一定电压,使第一场效应管 Q1 仍导通, 若一定时间后仍然没有点击操作, 则电容放电基本完成时, 第一场效应管的栅极 电压过低, 所述第一场效应管截止, 整个电路自动关断, 此时不再消耗任何能量, 当用户 再次点击后, 电路自动实时接通, 不影响使用。
本实施例中所述第一场效应管 Ql、 第二场效应管 Q2、第三场效应管 Q3可以用结型场效应 管、 绝缘栅型场效应管或者其它可以实现一定电压控制其开关的场效应管, 如 3018等。
