Description

一种在把手立柱内的开锁机构 技术领域
本发明涉及锁具的领域，具体涉及一种在把手立柱内的开锁机构。
背景技术
指纹锁因为给用户带来极大的方便而受到大家的欢迎，但是，现有的大部分指纹锁与传统机械锁有较大的区别，需要经过培训的专业人员安装、维护，使指纹锁有较大的使用成本，给普及带来障碍。
发明内容
本发明的目的在于克服现有技术存在的不足，而提供一种在把手立柱内的开锁机构，把整个指纹锁的结构部分都放置于把手内。使指纹锁的安装、使用最简化，降低指纹锁的使用成本，利于指纹锁的推广、普及。
本发明的目的是通过如下技术方案来完成的：这种在把手立柱内的开锁机构，主要包括步进电机、凸轮、滑块、离合A、离合B，步进电机与凸轮配合连接并能带动其旋转，外部套装有弹簧A的滑块位于凸轮正前方，使得凸轮向前旋转时能推动滑块并压缩弹簧A，离合A一端与弹簧A连接，另一端连接弹簧B，弹簧B又与离合B相连，步进电机外套装有电机盖A及电机盖B，离合A外套装有限位盖A及限位盖B，电机盖A与限位盖A、电机盖B与限位盖B相互配合连接并固定安装在把手内，离合B安装在把手内，在弹簧A的作用下离合A向前顶并能与离合B咬合，此时下压把手即可开门；开门完成后，步进电机反转并带动凸轮回转，滑块、离合A在弹簧B的作用下回退至原位，此时离合A与离合B分离，下压把手无法开门。
作为一种优选的技术方案，所述弹簧A的弹性系数大于弹簧B，保证即使在较小的行程下，弹簧A产生的弹力足够使离合A与离合B咬合。
本发明的有益效果为：整个指纹锁的结构部分都放置于把手内，使指纹锁的安装、使用最简化，降低指纹锁的使用成本，利于指纹锁的推广、普及。

具体实施方式
下面将结合附图对本发明做详细的介绍：
实施例：如附图所示，这种在把手立柱内的开锁机构，主要包括步进电机1、凸轮2、滑 块3、离合A5、离合B7，步进电机1与凸轮2配合连接并能带动其旋转，外部套装有弹簧A4的滑块3位于凸轮2正前方，使得凸轮2向前旋转时能推动滑块3并压缩弹簧A4，离合A5一端与弹簧A4连接，另一端连接弹簧B6，弹簧B6又与离合B7相连，步进电机1外套装有电机盖A9及电机盖B10，离合A5外套装有限位盖A11及限位盖B12，电机盖A9与限位盖A11、电机盖B10与限位盖B12相互配合连接并固定安装在把手8内，离合B7安装在把手8内，在弹簧A4的作用下离合A5向前顶并能与离合B7咬合，此时下压把手8即可开门；开门完成后，步进电机1反转并带动凸轮2回转，滑块3、离合A5在弹簧B6的作用下回退至原位，此时离合A5与离合B7分离下压把手无法开门。
所述弹簧A4的弹性系数大于弹簧B6，保证即使在较小的行程下，弹簧A4产生的弹力足够使离合A5与离合B7咬合。
本发明过程：当指纹有效开锁时，步进电机转动，带动凸轮旋转并推动滑块前顶直至凸轮最高点，滑块下压弹簧A，在弹簧A的作用下，离合A前顶直至离合B与离合A咬合，此时下压把手即可开门；开门延时时间到后，步进电机反转，带动凸轮回转，滑块、离合A在弹簧B作用下回退至初始位置，此时滑块位于凸轮最低点，离合A和离合B分离，即完成一次开门动作，两离合器分离后，下压把手无效，实现锁门。
当把手不在正常原位时(一般把手的正常原位是在水平位置)，离合器A、B相互错位，导致离合A无法下压，即无法与离合B配合，此时即使指纹验证通过，因为离合器不能完成配合，开锁失败。但是，由于指纹验证通过后，步进电机完成旋转过程，凸轮、滑块完成前顶动作，令弹簧A处于压紧状态，一旦把手回到原位(开锁时，开锁人发现无法开锁时，会下压把手几次尝试开锁)，离合A和离合B在弹簧A作用下即刻完成咬合，再次下压把手有效，并能完成开锁动作。
可以理解的是，对本领域技术人员来说，对本发明的技术方案及发明构思加以等同替换或改变都应属于本发明所附的权利要求的保护范围。
