Description
由电容储能实现自复位的锁芯装置及配套锁具和钥匙 所属技术领域
本发明涉及锁具, 尤其是电子锁具。 背景技术
在电子计算机技术迅速发展的今天, 尽管各式各样的应用了微电脑智 能技术的电子锁不断被发明并且相继被报道, 然而, 到目前为止, 这些各 式各样的电子锁却只能主要应用于体积较大的门锁。 现有的电子锁技术目 前还无法高度集成到一个足够小的体积以便使诸如抽屉锁、 橱柜锁、 箱包 锁、 机器设备锁等微小型锁具也实现微电脑智能化, 现有的电子锁技术更 不可能将人们常用的包括这些微小型锁具在内的各种钥匙全部统一到一把 钥匙或者一只手指头上, 因此, 尽管人类发明电子锁已经几十年并且后来 还发明了指紋电子锁, 但是我们除了在高级宾馆和少数高档办公室的门上 见到它们以外, 它们却很难在社会的广大家庭和办公室中推广和普及。
现有的电子锁 (包括指紋电子锁) 难以被推广和普及以及难以被高度 集成的重要原因在于锁中必须装有电池才能工作, 由于锁中电池的存在, 不但致使电子锁的体积庞大, 还使得在使用了一段时间以后更换电池成了 不可忽略的麻烦。 何时更换电池? 怎样更换电池?对于不同的电子锁来说 都有着很大的不确定性。 这样, 一旦由于人们长期出门在外或者由于人为 疏忽而没有及时更换电池, 或者由于天气寒流使得快要更换电池的电子锁 还没有来得及报警就失去电力的话, 其撬门砸锁的后果是非常令人不愉快 的。
为了克服现有电子锁的上述弊端, 在今天世界上已经公知的一些电子 锁的方案中正在尝试着将锁中的电源舍去, 当钥匙插入这种锁中无电源的 电子锁时, 钥匙内的电子线路就与锁中的电子线路构成一个完整的电路系 统, 此时电子锁的工作电源由插入电子锁的钥匙提供。其主要工作原理是, 当钥匙插入电子锁以后, 电子锁中含有微电脑的电子线路装置在验证了钥
匙所提供的开锁密码或开锁授权信息以后驱动电动机或机电驱动装置, 进 而电动机或机电驱动装置驱动一个用于传递开锁力量的具有 "可传动"和 "不可传动"两种离合状态的力传动离合装置。 该力传动离合装置类似于 汽车离合器的功能, 它可以传递以人手操作为动力的开锁力量使电子锁的 锁舌移动。 当力传动离合装置被驱动到 "可传动"状态时, 人手操作的开 锁力量可以移动锁舌, 而当力传动离合装置被驱动到 "不可传动"状态时, 人手操作的力量便不可以移动锁舌。 对于锁中没有电源的电子锁来说, 它 所面临的主要问题是, 当钥匙完成开锁而需要拔出电子锁的时候, 在锁中 电子线路没有电源的情况下, 如何将用于传递开锁力量的力传动离合装置 从开锁时的 "可传动"状态复位到钥匙插入前的 "不可传动"状态? 如果 一个电子锁在锁舌被上锁并且将钥匙拔出以后, 力传动离合装置并没有被 复位到 "不可传动"状态, 则此时的电子锁就会一直保持在可以开锁的状 态, 那么任何人在这种情况下都可以轻易将锁舌打开, 这对于电子锁的安 全和可靠使用是最最糟糕的! 为了解决这个严肃而困难的问题, 对于锁中 无电源的电子锁来说, 目前已经公知的解决方案是采用电子驱动和机械复 位相结合的方法。 具体地讲就是: 当需要移动锁舌时, 在钥匙插入电子锁 以后, 由锁中的电子线路装置驱动电动机使力传动离合装置由 "不可传动" 状态被驱动到 "可传动"状态, 从而使锁舌可以在人手操作的动力下移动, 这种由电动机驱动而改变了力传动离合装置的离合状态的过程被称为电子 驱动; 而当需要给锁舌上锁并且需要拔出钥匙的时候, 该公知的解决方案 是, 必须在拔出钥匙前先将钥匙进行反方向旋转, 利用人手操作的反方向 旋转力使力传动离合装置由 "可传动"状态被驱动到 "不可传动"状态, 然后再拔出钥匙, 从而使锁舌在钥匙拔出以后不可以被移动, 这种经由人 手操作的反方向旋转力而改变了力传动离合装置的离合状态的过程被称为 机械复位。 显然, 这种采用电子驱动和机械复位相结合方法的电子锁, 由 于它很重要的一部分工作需要由手动操作来完成, 所以从严格意义上来讲 它并不是真正意义上的智能电子锁, 它只能是属于一种半自动半手动或者 称为半电子半机械式的电子锁。 这种半自动半手动式的电子锁并不能充分 体现和发挥电子锁智能化的优势, 它不但使电子锁使用的可靠性和安全性 得不到保证, 还使得电子锁的机械结构复杂、 体积较大、 系统集成度低、
使用不方便, 因而无法在更多种类的锁具中使用。 此外, 这种半电子半机 械式的电子锁在钥匙的机械耐久性和电池更新的方便性等方面也存在着诸 多缺陷。 所以, 到目前为止, 这种电子锁其实也并没有真正得到社会和市 场的认同, 当然更无法进行推广和普及了。
本发明所要解决的主要问题是: 1、在电子锁锁中无电源而依靠钥匙提 供电源的情况下, 当钥匙完成开锁并拔出电子锁以后, 电子锁内的力传动 离合装置在没有人力操作的条件下, 应用电容器储能和微电脑智能技术实 现高可靠性电动复位。 2、 将包括门锁、 抽屉锁、 橱柜锁、 箱包锁、 设备锁 等在内的不同种类锁具的锁芯进行高度集成的统一模块化设计, 使得除门 锁以外的其它多种类锁具也能实现微电脑智能化, 从而真正实现用一把钥 匙打开所有种类的锁, 使每个人所有的钥匙真正都能够统一为一把。 3、 提 高钥匙使用的方便性和耐久性, 巧妙解决钥匙中电池能量的更新问题。 发明内容

本发明钥匙实施例:
本实施例的结构形式如图 1和图 2所示, 图 2是图 1的侧面局部剖 视图。 图 1中, 左端为钥匙头 7, 它由金属套 2、 触点 1和绝缘材料等构 成。 金属套 2裹在钥匙头 7的根部外表面, 在该金属套 2朝向钥匙头 7 的一端具有 U形缺口。 设计这样的金属套 2可以大大增强钥匙头 7的刚 性和机械强度以及使用寿命, 很好地将开锁时人手操作的旋转力传递给 锁中力传动离合单元的杠杆 22 (如图 8所示, 下面将详述), 从而导致 移动锁舌能获得强劲的力量。 在金属套 2的 U形缺口中, 安装了暴露在 U形缺口中的由触点 1组成的触点组, 在每个触点 1的周围都有绝缘材 料填充。 触点组的一侧外表面和绝缘材料与金属套 2的同侧外表面处在 同一个平面上。 钥匙头 7上触点 1的安装位置分别与通用计算机国际标 准 USB接口插头的触点安装位置一一对应, 也就是说, 钥匙头 7的机械 尺寸以及触点 1的安装位置都与国际标准 USB接口插座相配套,这样就 为本发明的钥匙通过通用计算机得到更多的技术支持和功能支持而提供 了可能。关于 USB接口插头的定义, 有关国际行业组织早已有明确的规 定并且早已经公布。 在图 1中, 钥匙头 7上的触点组可以是单面的, 也 可以是双面的; 如果是单面触点组, 在图 1所示的背面也可以见到金属 套 2在该面上的 U形缺口, 并且有绝缘材料将该面的 U形缺口填平; 如

为使本发明的钥匙在旋转开锁时无法随意拔出, 本发明的钥匙在钥 匙头 7上设有孔 8 (图 1所示), 该孔 8可以是通孔, 也可以是盲孔 (俗 称为 "凹坑"), 其工作原理将在下面的智能锁芯装置实施例之一中阐述。
图 1和图 2的右端是本实施例的外壳 3, 在外壳 3的内部有钥匙电 路单元 5, 钥匙电路单元 5通过导线与触点 1一一相连。 在钥匙电路单 元 5中包括电池 E和带有非易失性存储器的微电脑 4 (CPU或称微处理 器), 在微电脑 4的非易失性存储器中存储有代表每把钥匙的密码。 图 3 是本实施例钥匙电路单元的电路原理图, 图中, 钥匙头触点组的 R端是 唤醒或复位端, VC是可控的电源输出端, S是双向串行信号通讯端, G 是公共接地端。 关于钥匙电路单元与智能锁芯装置配套使用的工作原理 将在下面的智能锁芯装置实施例中阐述。
在图 3中, 电池 E可以设计成普通钮扣电池, 也可以设计成可充电 电池。 如果电池 E不是可充电电池, 则图 3中由限流电阻 R2和隔离二 极管 D2构成的支路将断开移去。 如果电池 E是可充电电池, R2和 D2 将按图 3所示被接入, 这样, 本实施例的钥匙就可以直接插入到通用计 算机的 USB接口中, 利用 USB接口中的电源对电池 E进行充电。 本发明智能锁芯装置实施例之一:

(即图 4的左视图), 图 6是图 4中移去电子线路单元 25后的右视图。 在图 4中: 圆筒 13、 绝缘材料 12、 触点 14和活动柱体 31等构成了钥匙 插孔单元; 圆管 16、 转盘 18、 杠杆 22、 杠杆轴 21、 杠杆支架 32、 限位 挡块 19以及磁铁 20等构成了力传动离合单元,其中圆管 16可根据本智 能锁芯装置的实际应用可以增长或缩短; 电动机 Ml、 电动机 M2、 开锁 驱动丝线 24、 复位驱动丝线 30、 导向部件 17、 支架 33以及压线环 28 等构成了机电驱动单元; 在该机电驱动单元中, 包含了由电动机 M2、 开
锁驱动丝线 24和压线环 28构成的开锁驱动机构, 以及由电动机 Ml、复 位驱动丝线 30、压线环 28、导向部件 17以及支架 33构成的电动复位机 构; 微电脑 23、 储能电容器 C1以及其它电子元件等被安装在一块电路 板上构成了电子线路单元 25。
由图 4, 力传动离合单元中圆管 16的一端与钥匙插孔单元中的圆筒 13进行力传动连接, 转盘 18固定在圆管 16的另一端, 杠杆 22通过装 有杠杆轴 21的两个杠杆支架 32安装在转盘 18上。 杠杆轴 21的中轴线 与转盘 18的盘面平行,两个杠杆支架 32与部分转盘 18的盘面构成了一 个 U形, 杠杆 22在该 U形空间内绕杠杆轴 21转动。 杠杆 22的主体为 中间有轴孔的钢质方柱体,在该方柱体的尾端固定了一段钢丝 35与它成 为一体 (图 6), 该钢丝 35的中轴线与杠杆 22轴孔的中心线平行, 在图 6和图 9中钢丝 35与方柱体构成了一个 "L"形状。 当钥匙插入到钥匙 插孔 11并且旋转时 (图 8), 可以带动圆筒 13、 圆管 16、 转盘 18以及 杠杆 22等一起转动,从而将人手操作钥匙的旋转力通过钥匙插孔单元传 递给力传动离合单元。 力传动离合单元中的杠杆 22具有两个工作位置, 当它处于如图 8、 图 9所示的位置时, 则可以将人手操作钥匙的旋转力 通过其露出转盘 18圆周以外的端部传递给其它机械零件;而当它处于如 图 4、 图 6所示的位置时, 则无法将人手操作钥匙的旋转力传递给其它 机械零件。杠杆 22的这两个工作位置决定了力传动离合单元具有可传动 和不可传动两种工作状态, 它的功能就像汽车用于传递引擎动力的离合 器一样, 具有 "离"或 "合"两种不同的离合状态。 当杠杆 22被驱动到 如图 4、 图 6所示的位置时, 称之为 "杠杆 22被复位", 杠杆 22被复位 的位置称之为 "复位位置"。
驱动杠杆 22动作而改变力传动离合单元的离合状态是由包含了两 个电动机的机电驱动单元来实现的, 机电驱动单元也被安装在转盘 18 上。 其中电动机 M2用于开锁驱动, 在它的轴端通过压线环 28连接一段 柔软的丝线 (称为开锁驱动丝线 24), 该开锁驱动丝线 24的另一端固定 在与杠杆 22连接的钢丝 35上。 电动机 Ml用于复位驱动, 在它的轴端 通过压线环 28也连接一段柔软的丝线 (称为复位驱动丝线 30), 该复位 驱动丝线 30的另一端绕过导向部件 17也固定在与杠杆 22连接的钢丝
35上。 当电动机 M2在脉冲电流的驱动下转动, 电动机 M2的轴卷绕开 锁驱动丝线 24, 并拉动钢丝 35从而将杠杆 22驱动到如图 8、 图 9所示 的位置。 当电动机 Ml在脉冲电流的驱动下转动, 电动机 Ml的轴卷绕 复位驱动丝线 30, 复位驱动丝线 30在导向部件 17的作用下使拉力方向 改变以便于从另一个方向上拉动钢丝 35, 从而将杠杆 22复位到如图 4、 图 6所示的位置。 导向部件 17是一个圆柱形的轴状体, 它通过支架 33 固定在转盘 18上 (图 6所示)。 安装在转盘 18上的限位挡块 19对杠杆 22的活动起限位作用。 磁铁 20固定在限位挡块 19上, 当杠杆 22被驱 动到上述两个工作位置时, 磁铁 20对杠杆 22有吸合力从而保证杠杆 22 在两个工作位置的稳定。
在钥匙插孔单元的中轴线上, 是一个截面为扁矩形的钥匙插孔 11, 在圆筒 13 的空腔内围绕钥匙插孔 11有绝缘材料 12填充, 触点 14的尾 部嵌入到绝缘材料 12内, 触点 14的其余部分暴露在钥匙插孔 11内。 由 图 5可见, 本实施例的触点 14一共有 4个, 它们全部设于钥匙插孔 11 内的一侧, 每个触点 14的安装位置都与通用计算机 USB接口插座的触 点安装位置相对应。
在钥匙插孔 11内触点面的对面一侧, 有一个通孔贯穿于绝缘材料 12和圆筒 13,孔内设有当本智能锁芯装置装入到电子锁或电子锁头的外 壳时可以限定钥匙只能在确定旋转位置拔出的活动柱体 31, 如图 10所 示。 当本实施例的智能锁芯装置装入到电子锁或电子锁头的外壳 39时, 在外壳 39下面有一个与活动柱体 31同心且可以使其活动的通孔与它相 配合, 在该通孔里面安装了滑块 36、 弹簧 38和塞子 37; 塞子 37紧紧塞 在外壳 39上, 使弹簧 38的下端不能移动, 弹簧 38的上端顶住滑块 36 进而顶住活动柱体 31, 于是活动柱体 31端部的锥形头便被顶出到钥匙 插孔 11中。智能锁芯装置被装入到外壳 39以后, 它可以在外壳 39的空 腔内跟随插入的钥匙头 7—起转动,当智能锁芯装置位于外壳 39中如图 11所示的正位位置时, 智能锁芯装置的装有活动柱体 31的通孔与外壳 39下面通孔的中心线为同一直线; 此时当钥匙头 7插入如图 10或图 11 (图 11是图 10的 B-B线剖视图)所示的钥匙插孔 11时,钥匙头 7的前 端通过斜面的力作用推动活动柱体 31并压迫滑块 36和弹簧 38向下移
动; 当钥匙头 7完全插入钥匙插孔 11后, 活动柱体 31的头部落于钥匙 头 7的孔 8中, 并且活动柱体 31的下端部与滑块 36的相交面正处于圆 筒 13与外壳 39内腔的弧形相交面上, 此时如果旋转钥匙可以带动活动 柱体 31跟随智能锁芯装置的圆筒 13—起转动, 但如果在转动后要拔出 钥匙头 7, 由于活动柱体 31的中轴线与外壳 39下面通孔的中心线已不 在同一直线上, 使得活动柱体 31因外壳 39内壁的限制而无法滑动并脱 离孔 8, 于是钥匙头 7无法在非正位位置拔出 (如图 12所示)。 由于钥 匙头上孔 8和活动柱体 31的作用,钥匙头 7只有在智能锁芯装置位于如 图 11所示的正位位置才能插入或拔出,这样设计的目的是为了保证钥匙 在未完成旋转开锁的任务以前与锁或锁头有可靠的电接触, 以及为防止 钥匙在完成开锁任务以后拔出时因智能锁芯装置处在非正位位置而可能 使杠杆 22的复位动作被其它机械零件卡住失灵。
在图 4中, 电子线路单元 25被固定在转盘 18的固定柱 26上, 电子 线路单元 25通过导线 15与钥匙插孔单元内的触点 14电连接, 并且通过 导线与电动机 Ml和电动机 M2电连接。 在圆筒 13和转盘 18上具有导线 15的出线孔, 该出线孔可以由中轴孔 34替代, 也可以在其它方便的位置 产生。
图 7是本实施例以及本发明的智能锁芯装置、 电子锁或电子锁头各实 施例中电子线路单元的通用电路原理图, 图中整个电路的供电能源依赖钥 匙插孔触点组中的触点 VC提供。 其中, C1为储能电容器, 二极管 D和 升压电路构成了可对储能电容器 C1进行高于电源电压充电的升压充电电 路; 设计升压充电的目的是为了能给电动机 Ml提供更大的驱动能量, 以 便更可靠地使杠杆 22由可传动状态被驱动 (复位) 到不可传动状态。 升 压电路的 1端为电源输入端, 升压电路的 3端为升压后的电源输出端, 升 压电路的 2端为充电控制端 (由 CPU的 F2端控制), 当 CPU的 F2端以 高低电平交替的脉冲方式变化时升压电路将输入电压提升后对储能电容 器 C1充电, 当不需要充电时 CPU的 F2端停止在高电位。 升压电路的构 成可以是图 7中的电感升压方式, 也可以选择用 DC-DC集成电路模块来 实现。 当然, 如果电动机 Ml的功率足够大或者电容器 C1的容量足够大 则也可以舍去升压电路, 此时将 CPU的 F2端或者钥匙插孔触点组中的
VC端接到二极管 D的正极, 从而构成对电容器 C1不升压的充电电路。 在图 7中, 晶体管 VI、 电阻 R1和 CPU的 El、 B1端构成了可以驱动和 控制电动机 Ml正转或反转的双向驱动控制电路, 当储能电容器 C1上充 满电压并且 CPU的 B1端处于高阻浮空状态时,如果 CPU的 E1端由低电 平变为高电平则将晶体管 VI开通从而使电动机 Ml正向转动; 而当储能 电容器 C1上没有电压并且 CPU的 E1端处于低电平使晶体管 VI关断时, 如果 CPU的 B1端输出高电平则可在短时间内使电动机 Ml反向转动。 同 样, 晶体管 V2、 电阻 R2以及 CPU的 E2、 B2、 F2端构成了可以驱动和 控制电动机 M2正转或反转的双向驱动控制电路, 当 CPU的 F2输出高电 平并且 B2端处于高阻浮空状态时,如果 E2端由低电平变为高电平则将晶 体管 V2开通从而使电动机 M2正向转动; 而当 CPU的 E2端处于低电平 使晶体管 V2关断并且 CPU的 F2端以脉冲方式输出低电平时, 如果 CPU 的 B2端输出高电平则可使电动机 M2以步进的脉动方式反向转动。 图 7 中 W是电磁开关器件,它会在磁场的作用下使晶体管 V2的基极对地短路, 从而保证在不希望钥匙开锁的情况下使电动机 M2失去电源驱动而阻止开 锁, 在本实施例中, W是干簧管开关(当然它也可以换成霍尔电子开关), 它将根据本智能锁芯装置在电子锁或电子锁头中的实际使用而考虑接入 还是移去。
在图 7中, 带有非易失性存储器的微电脑 (CPU或称微处理器) 中 事先存储有允许开锁的钥匙的密码, 在钥匙插孔触点组中, R端连接电 容器 C3用于向钥匙提供唤醒或复位信号, VC是电源输入端, S是双向 串行信号通讯端, G是公共接地端。 当如图 3所示的钥匙插入到如图 7 所示的智能锁芯装置的钥匙插孔时, 图 3中钥匙头的触点 、 VC、 S、 G 与图 7中钥匙插孔中的同名触点 R、 VC、 S、 G分别连通, 于是, 图 3 中唤醒或复位电路的 F端将得到由图 7中电容 C3产生的一个短暂的低 电平信号(在唤醒或复位电路的内部, F端与 VCC之间有一个上拉电阻 使 F端平时都为高电平), 然后图 3中唤醒或复位电路的 R端输出低电 平信号使钥匙的 CPU唤醒或复位。 当钥匙的 CPU被唤醒或复位以后, 钥匙 CPU的 A1端将由高电平转为低电平, 并通过图 3中电阻 R1使晶 体管 V开通, 于是, 钥匙中的电池 E经过图 3中隔离二极管 Dl、 开关
三体管 V以及触点 VC向图 7电路提供电源。图 7电路在得到电源以后, 首先向具有滤波和储能作用的电容器 C2充电以及向图 7中的 CPU供电。 图 7中的 CPU在得电以后首先对其各种状态进行初始化设置,其中包括 令 E1端和 E2端处于低电平、 令 B1端和 B2端高阻浮空、 令 F2端处于 高电平等。 紧接着图 7中的 CPU令 B1端输出高, 使电动机 Ml短时间 反向转动, 为的是松开电动机 Ml在前一次正转时 (即前一次钥匙拔出 钥匙插孔后驱动杠杆 22复位时) 卷绕在其轴端的复位驱动丝线 30, 从 而为其后再次驱动电动机 Ml时能得到较好的驱动初速度和初动力而做 好准备。 然后, 图 7中的 CPU令其 B1端由高电平变为高阻浮空状态, 同时控制其 F2端使升压充电电路向储能电容器 C1充电。 在经过一个预 定的充电时间以后, 图 7中的 CPU令 F2为高电平并通过信号线 (即触 点 S端) 向钥匙询问开锁密码, 钥匙在得到询问密码的命令后也将通过 信号线(即触点 S端)向图 7电路回答钥匙所携带的密码。图 7中的 CPU 在得到钥匙回答的密码后将判断其与事先存储在该 CPU中的钥匙的密 码是否一致; 如果钥匙回答的密码正确, 在电磁开关器件 W不存在或未 接通的情况下, 图 7中的 CPU则通过其 E2端使晶体管 V2开通, 从而 驱动电动机 M2正向转动, 于是杠杆 22被驱动到可传动状态使开锁成为 可能; 如果钥匙回答的密码不正确, 则图 7中的 CPU其后将不需要进行 任何操作。 由前述, 图 7中的 CPU在驱动电动机 M2正向转动并使杠杆 22被驱动到可传动状态以后, 紧接着通过控制其 B2端、 F2端和 E2端 使电动机 M2有一个短时间的反向转动, 为的是松开电动机 M2在刚才 正转时卷绕在其轴端的开锁驱动丝线 24, 从而为其后电动机 Ml的复位 驱动不被电动机 M2的牵扯而做好准备。 除此之外, 在钥匙完成回答密 码以后, 钥匙电路单元将不断地向图 7电路发送约定的电子信号以表明 钥匙此时并没有拔出智能锁芯装置的钥匙插孔, 该约定信号可以约定为 各种形式, 比如可以是一个持续的高电平, 也可以是不间断的脉冲信号 等等。与之相配合的是, 在本发明智能锁芯装置的电子线路单元 25中设 有当钥匙拔出钥匙插孔 11时能检测钥匙头 7离开钥匙插孔 11的检测电 路, 在本实施例中, 该检测电路兼由 CPU的 F1端和电阻 R3实现。 在 图 7中的 CPU得到钥匙回答的密码以后,它将立即不间断地检测来自钥
匙的约定信号是否存在, 如果钥匙被拔出钥匙插孔 11, 则图 7电路来自 钥匙的供电能源以及来自钥匙的约定信号会立即消失, 于是, 图 7中的 CPU依靠电容器 C2维持短暂的供电,并且在电容器 C2短暂的供电消失 之前判断来自钥匙的约定信号已确实不存在, 然后, 图 7中的 CPU将立 即开通开关三极管 VI, 使得被充有较高电压的储能电容器 C1以放电的 方式向电动机 Ml供电并使其正向转动, 从而导致力传动离合单元 (或 杠杆 22) 由可传动状态被驱动到不可传动状态, 以完成钥匙拔离后智能 锁芯装置的电动复位。 本发明智能锁芯装置实施例之二:
根据前述智能锁芯装置实施例之一, 其机电驱动单元中所包含的电动 复位机构由电动机 Ml、 复位驱动丝线 30、 压线环 28、 导向部件 17以及 支架 33构成, 如果移除前述智能锁芯装置实施例之一中电动复位机构所 包含的导向部件 17和支架 33, 将电动复位机构改由电动机 Ml、 复位驱 动丝线 30、压线环 28、受电动机 Ml驱动可对杠杆 22施力的滑动件 101、 安装滑动件 101的导轨 104、 对滑动件 101施力的滑动件弹簧 106、 以及 一个可传递钥匙插入钥匙插孔 11时的顶推力从而导致滑动件 101 由复位 位置滑动到非复位位置的顶杆 107、 对顶杆 107施力并力图使顶杆 107恢 复到初始状态的顶杆弹簧 105、 安装顶杆弹簧 105的扭簧轴 103等构成, 则可以得到本实施例。
在本实施例中, 除电动复位机构以外的其它所有部分的组成和构成形 式、 电子线路和微电脑 23 的工作程序、 以及它们的工作原理都与前述智 能锁芯装置实施例之一相同, 也就是说, 将前述智能锁芯装置实施例之一 中的电动复位机构换成本实施例的电动复位机构即可得到本实施例。
图 13是本实施例的侧面剖视图 (即图 22中 J-J剖视图), 其中, 滑 动件 101、 扭簧臂 102、 扭簧轴 103、 导轨 104、 顶杆弹簧 105、 滑动件 弹簧 106、 顶杆 107、 以及电动机 Ml、 电动机 M2、 压线环 28、 开锁驱 动丝线 24、 复位驱动丝线 30等按照所在安装位置的投影在图中表现。 图 22是本实施例的正面视图, 也是图 13的左视图, 图 23是图 13中移 去电子线路单元 25后的右视图, 图 24是图 23中沿 K-K剖面线的局部
剖视图, 图 24中隐去了不属于电动复位机构的元件。
在图 13中, 顶杆 107被放大后的零件图如图 14所示, 图中可见, 顶杆 107的主体部分是圆柱形的长杆 113, 在长杆 113中部偏左的位置 设有限位台阶 110, 在长杆 113的右端设有弯臂 111, 在弯臂 111的端部 设有通孔 112。 图 15是图 14的左视图, 图 16是图 14右视图。
在图 13中, 滑动件 101被放大后的零件图如图 17所示, 图 18是图 17的右视图, 图 19是图 17的左视图, 图 20是图 18的底视图, 图 21 是图 20的右视图。 滑动件 101由铁板冲压并折弯后形成, 它具有孔 121 和孔 126 (图 18、 图 19), 并且这两孔同轴。 由图可见, 如果在滑动件 101的孔 121和孔 126中穿过一根轴作为支点, 则滑动件 101还具有相 当于杠杆原理的动力臂 125和阻力臂 123 (图 18、 图 19), 其中在动力 臂 125的中部设有通孔 120。 由图 18、 19、 20可见, 滑动件 101还具有 一个用于钩挂弹簧的挂钩 124以及一个可对力传动离合单元施力的前端 127 (图 17、 18、 19)。 此外, 在滑动件 101的阻力臂 123上还有一个被 折弯的与阻力臂 123成 90度夹角的三角翼, 在该三角翼上有一个斜面 122 (图 17、 图 18)。
由图 13可见, 圆筒 13和转盘 18的中轴线上具有中轴孔, 顶杆 107 安装在中轴孔中, 它的一端设在钥匙插孔 11中, 它的另一端穿出钥匙插 孔 11和转盘 18与顶杆弹簧 105的扭簧臂 102进行受力连接。 顶杆弹簧 105实际上是一个扭簧, 它通过扭簧轴 103安装在固定柱 26上(图 23 ); 顶杆弹簧 105作为扭簧有两个臂, 其中一个固定臂 130固定在固定柱 26 上, 另一个扭簧臂 102穿过顶杆 107弯臂 111上的通孔 112并压迫顶杆 107向着钥匙插孔 11的方向受力 (即向外受力, 图 24), 由于顶杆 107 上台阶 110的限位作用, 顶杆 107将停在恰当的位置, 顶杆弹簧 105总 是力图使顶杆 107恢复到初始状态。 在本实施例中, 由于中轴孔内安装 了顶杆 107, 所以连接触点 14和电子线路单元 25的导线 15的出线孔不 能由中轴孔替代, 须在圆筒 13和转盘 18上其它方便的位置产生。
由图 23可见, 在顶杆 107的左侧, 导轨 104被固定在转盘 18上, 它 实际上就是一个圆柱形的轴,滑动件 101通过其自身的孔 121和孔 126套 在该导轨 104上, 使得滑动件 101既可以绕导轨 104转动也可以在其上滑
动。滑动件 101动力臂 125上的通孔 120系着复位驱动丝线 30,复位驱动 丝线 30的另一端通过压线环 28固定在电动机 Ml的轴上 (图 13 )。 滑动 件弹簧 106钩挂在滑动件 101的挂钩 124上,滑动件弹簧 106的另一端通 过镙丝斜拉固定在转盘 18上。由图 23可见,滑动件弹簧 106对滑动件 101 有一个斜拉力 F,从而导致滑动件 101绕导轨 104按图中 S方向受力旋转; 同时, 该斜拉力 F还在滑动件 101滑动轨迹的方向上被分解为拉力 G (图 24箭头所示), 从而导致滑动件 101被拉动受力并总是力图贴近转盘 18。 在图 23中, 固定柱 26和圆柱 131将对滑动件 101的旋转角度进行限位, 在电动机 Ml未驱动滑动件 101动力臂 125的情况下, 滑动件 101的阻力 臂 123位于顶杆弹簧 105的扭簧臂 102的上方 (如图 23和图 24所示)。 当本发明钥匙插入到本实施例的钥匙插孔 11时, 如图 26所示, 钥匙头 7 将顶杆 107向内推进(图 26中向右端),于是,顶杆 107带动顶杆弹簧 105 的扭簧臂 102向着钥匙顶推力的方向运动, 进而扭簧臂 102托举起滑动 件 101的阻力臂 123使滑动件 101向着离开转盘 18的方向滑动(图 25中 箭头 H所示)。 当钥匙推进到位时, 滑动件 101被托举到位停止的高度正 好可以使滑动件 101不妨碍力传动离合单元中的杠杆 22能够被驱动到可 传动状态(如图 26所示),此时滑动件 101所处的位置称为非复位位置(见 图 25 )。而当本发明钥匙未插入或已拔离本实施例的钥匙插孔 11时,如图 13所示,顶杆 107被顶杆弹簧的扭簧臂 102推到最左侧从而解除对滑动件 101的托举, 于是滑动件 101在弹簧 106的拉力作用下 (参见图 24 )其前 端 127总是迫使力传动离合单元中的杠杆 22位于不可传动状态 (图 13 ), 此时滑动件 101所处的位置称为复位位置 (参见图 24)。 由此可见, 在本 实施例中,电动复位机构所包含的滑动件 101、导轨 104、滑动件弹簧 106、 顶杆 107、 顶杆弹簧 105以及扭簧轴 103在事实上构成了一个兼有机械复 位功能的机械复位机构。该机械复位机构在很多情况下并不需要借助电动 力也不管滑动件 101是否被驱动, 在钥匙拔离钥匙插孔 11 以后总是可以 将滑动件 101停留在复位位置, 从而使力传动离合单元中的杠杆 22由可 传动状态被驱动到不可传动状态。然而, 这种机械复位功能对于锁具的使 用来说是不可靠和不安全的;假如顶杆 107由于生锈或被人为恶意破坏而 卡在如图 27所示的位置, 那么该机械复位机构无论如何也不可能将杠杆
22复位到不可传动状态;在这种情况下, 当一把允许开锁的钥匙插入钥匙 插孔 11完成开锁并且拔离以后, 由于顶杆 107不能复位而导致力传动离 合单元中的杠杆 22无法复位, 于是, 在此之后的任何人不需要钥匙只要 转动钥匙插孔 11就可以很方便地将锁打开。 为避免这种情况的发生, 避 免由于顶杆 107的故障或被人为恶意破坏而造成锁具使用的不可靠和不安 全, 本实施例所采用的前述包含了电动机 Ml、 滑动件 101 以及顶杆 107 等构成的电动复位机构是必须的。 当钥匙插入钥匙插孔 11 完成开锁并且 拔离以后, 如果顶杆 107被卡在如图 27所示的位置 (此时滑动件 101正 在被顶杆弹簧的扭簧臂 102托举着, 图 25 ), 电子线路单元将根据钥匙已 经离开的检测结果驱动电动机 Ml卷绕复位驱动丝线 30,从而驱动滑动件 101旋转到如图 28所示的位置(图中箭头 K为旋转方向)。 滑动件 101在 被驱动旋转的过程中一旦到达图 28所示的位置, 其阻力臂 123就会立刻 从顶杆弹簧的扭簧臂 102上滑脱, 于是, 在滑动件弹簧 106的拉力作用下 使滑动件 101 到达复位位置 (见图 29) 并且在电动机 Ml 的驱动力消失 以后使滑动件 101回复到开锁前的初始位置 (见图 30)。 滑动件 101在从 顶杆弹簧的扭簧臂 102上滑脱到达复位位置的过程中, 其前端 127将压迫 杠杆 22,迫使其从可传动状态旋转到不可传动状态,从而实现了本实施例 的电动复位机构将力传动离合单元由可传动状态驱动到不可传动状态的 复位过程。在本实施例中, 这种具有机械复位和电动复位双重复位功能的 锁具具有很高的可靠性和安全性。
根据上述, 当钥匙插入钥匙插孔 11完成开锁并且拔离,如果顶杆 107 被卡在如图 27所示的位置, 在电动复位机构完成复位以后, 滑动件 101 的阻力臂 123将会位于顶杆弹簧扭簧臂 102的下方 (如图 29、 30所示); 此时, 如果顶杆 107能够解除故障, 则顶杆弹簧的扭簧臂 102就会在推动 顶杆 107的过程中对滑动件 101的斜面 122施力, 迫使滑动件 101的阻力 臂 123向着避让的方向旋转 (图 31中箭头 K所示) 从而使扭簧臂 102能 够掉落到阻力臂 123的下方, 于是, 顶杆 107、 滑动件 101以及整个电动 复位机构都会回复到开锁前的初始状态 (如图 13、 23所示)。
本实施例中, 除电动复位机构以外的其它所有部分的组成和构成形式 以及工作原理都与前述智能锁芯装置实施例之一相同并已在智能锁芯装
置实施例之一中叙述, 在此不再赘述。 本发明电子锁实施例:
这是一个将上述智能锁芯装置实施例之一或智能锁芯装置实施例之 二应用于抽屉锁或橱柜锁的实施例。 由于上述智能锁芯装置实施例之一 和智能锁芯装置实施例之二在应用中与外界发生联系的部分无论是结构 形式还是工作原理都完全相同, 因此, 上述智能锁芯装置实施例之一或 智能锁芯装置实施例之二在本实施例中应用的过程以及工作原理的叙述 也是完全相同的。 为方便起见, 我们将上述智能锁芯装置实施例之一和 智能锁芯装置实施例之二在本实施例中统称为本发明智能锁芯装置, 这 表示所叙述的本发明智能锁芯装置既针对上述智能锁芯装置实施例之一 也同时针对上述智能锁芯装置实施例之二, 并且在附图中隐去了它们所 包含的仅在其内部发挥功能作用的电动复位机构。
图 32是本实施例的侧面剖视图 (即图 33中 C-C剖视图), 图 33是 图 32中移去电子锁后盖 49和电子线路单元 25后的右视图。 在图 32和 33中, 电子锁外壳 41和后盖 49的空腔内安装有本发明智能锁芯装置以 及一个可以在该空腔内上下滑动的锁舌装置; 其中, 本发明智能锁芯装 置中的圆管 16被缩短并且舍去了图 7中的电磁开关器件 W。 锁舌装置 包括下部为马蹄形的锁舌 42、 设在锁舌 42上的圆柱形的驱动挡块 45以 及可以阻止锁舌 42在锁住时滑动的自锁杠杆 43。 在图 33中, 自锁杠杆 43的上面有一个扭簧 44对自锁杠杆 43起作用, 该扭簧 44总是力图使 自锁杠杆 43向图中逆时针方向转动; 扭簧 44的一个臂作用于柱形挡块 46, 扭簧 44的另一个臂作用于自锁杠杆 43的上臂。 自锁杠杆 43的中部 有轴孔, 轴 47将扭簧 44和自锁杠杆 43穿在一起并安装在锁舌 42上。 在外壳 41上设有当锁舌 42在锁住时可以阻止自锁杠杆 43滑动的台阶 48, 当锁舌 42或锁舌装置位于如图 33所示的锁住位置时, 绕轴 47转动 的自锁杠杆 43的下臂端处于外壳 41的台阶 48之上, 从而保证锁舌 42 不能向开锁的方向滑动。 当钥匙插入到本电子锁实施例开锁时, 锁中的 电子线路单元 25在验证钥匙回答的密码正确后则命令机电驱动单元将 力传动离合单元驱动到可传动状态, 于是, 杠杆 22被驱动到如图 34和
35所示的可以进行开锁力量传动的位置; 此时, 按照图 36中所示的箭 头方向旋转钥匙, 则跟随钥匙和转盘 18—起旋转的杠杆 22的端部就会 首先推开锁舌 42上的自锁杠杆 43的上臂, 于是自锁杠杆 43绕轴 47转 动进而使自锁杠杆 43的下臂端脱离外壳 41上的台阶 48;继续旋转钥匙, 杠杆 22的端部将会将人手开锁的旋转力传递给驱动挡块 45进而使得锁 舌 42向开锁的方向滑动, 直到锁舌 42被完全开锁为止(如图 37所示)。 当锁舌 42被开锁并且在拔出钥匙时, 杠杆 22会在电动复位机构的驱动 下被复位到不可传动状态; 在这种情况下, 再次插入一把可以开锁的钥 匙, 则杠杆 22将再次被驱动到可传动状态, 此时如果按照图 38和图 39 中的箭头方向旋转钥匙,就可以使杠杆 22的端部从另一个方向上对驱动 挡块 45施力; 继续旋转钥匙, 直到锁舌 42被移动到完全锁住的位置。 当锁舌 42到达完全锁住的位置时, 自锁杠杆 43的下臂端会在扭簧 44的 作用下扣在外壳 41的台阶 48上, 从而实现锁舌 42的安全上锁。
在本实施例中, 由于本发明智能锁芯装置上活动柱体 31、 以及外壳 41上滑块 36、 弹簧 38和塞子 37的作用, 使得钥匙只能在转盘 18位于 如图 32或 33所示的位置才能插入或拔出, 从而避免了锁舌装置上的零 件对杠杆 22的活动发生干扰。 本发明电子锁头实施例之一:
这是一个将上述智能锁芯装置实施例之一或智能锁芯装置实施例之 二应用于外挂式电子锁头的实施例。 由于上述智能锁芯装置实施例之一 和智能锁芯装置实施例之二在应用中与外界发生联系的部分无论是结构 形式还是工作原理都完全相同, 因此, 上述智能锁芯装置实施例之一或 智能锁芯装置实施例之二在本实施例中应用的过程以及工作原理的叙述 也是完全相同的。 为方便起见, 我们将上述智能锁芯装置实施例之一和 智能锁芯装置实施例之二在本实施例中统称为本发明智能锁芯装置, 这 表示所叙述的本发明智能锁芯装置既针对上述智能锁芯装置实施例之一 也同时针对上述智能锁芯装置实施例之二, 并且在附图中隐去了它们所 包含的仅在其内部发挥功能作用的电动复位机构。
图 40是本实施例的侧面剖视图 (即图 41中 D-D剖视图), 图 41是
本实施例的正面视图也是图 40的左视图, 图 42是图 40的右视图。在图 40中, 外挂式电子锁头外壳 51的空腔内安装有本发明智能锁芯装置和 一个可以在外壳 51内转动的从动旋转装置; 其中, 本发明智能锁芯装置 中的圆管 16被缩短并且舍去了图 7中的电磁开关器件 W; 从动旋转装 置包括一个安装在外壳 51内的从动转盘 53, 该从动转盘 53是一个碗状 旋转体, 在它的外侧中心设有力传动输出杆 54, 该力传动输出杆 54为 柱状, 主要用于扭力的传动, 其横截面可以是各种非圆形的形状 (在本 实施例中为叶片状的扁矩形); 在从动转盘 53的内侧边缘设有受杠杆 22 驱动的驱动挡块 52 (参见图 40中沿 E-E线剖开的剖视图图 44)。 图 43 是市场上出售的可以与本实施例配套使用的机械门锁锁舌机构 (俗称锁 体) 的局部剖视图, 本实施例通过外壳 51上的螺紋 55固定在该锁舌机 构上, 并且在固定时将力传动输出杆 54插入到它的扭力传动孔 64中, 扭力传动孔 64位于锁舌拨轮 63的中心, 锁舌拨轮 63上具有拨齿 62。 当本实施例的力传动输出杆 54带动锁舌拨轮 63转动时,位于外壳 60内 的锁舌 61将随拨齿 62的移动或开锁或上锁。
图 45是本实施例中当一把可以开锁的钥匙插入到钥匙插孔 11中, 机电驱动装置驱动杠杆 22使得它处于可传动状态时的剖面示意图。在图 45中, 如果旋转钥匙, 杠杆 22就会将来自钥匙的人手开锁的旋转扭力 传递给驱动挡块 52,同时驱动挡块 52将该旋转扭力传递给从动转盘 53, 从而带动图 40中的力传动输出杆 54以及图 43中的锁舌拨轮 63—起转 动以实现锁舌 61的开锁或上锁。 当钥匙被拔出钥匙插孔 11时, 杠杆 22 会在电动复位机构的驱动下被复位到不可传动状态。
在本实施例中, 由于本发明智能锁芯装置上活动柱体 31、 以及外壳 51上滑块 36、 弹簧 38和塞子 37的作用, 使得钥匙只能在转盘 18位于如 图 40或 44所示的位置才能插入或拔出, 从而避免了从动转盘 53上的驱 动挡块 52对杠杆 22的活动发生干扰。
用本实施例的电子锁头去替换同类型的机械锁头,可以立即将原来的 机械锁升级为电子锁。 本发明电子锁头实施例之二
这是一个将上述智能锁芯装置实施例之一或智能锁芯装置实施例之 二应用于插芯式电子锁头的实施例。 由于上述智能锁芯装置实施例之一和 智能锁芯装置实施例之二在应用中与外界发生联系的部分无论是结构形 式还是工作原理都完全相同, 因此, 上述智能锁芯装置实施例之一或智能 锁芯装置实施例之二在本实施例中应用的过程以及工作原理的叙述也是 完全相同的。 为方便起见, 我们将上述智能锁芯装置实施例之一和智能锁 芯装置实施例之二在本实施例中统称为本发明智能锁芯装置,这表示所叙 述的本发明智能锁芯装置既针对上述智能锁芯装置实施例之一也同时针 对上述智能锁芯装置实施例之二, 并且在附图中隐去了它们所包含的仅在 其内部发挥功能作用的电动复位机构。
图 46是本发明电子锁头实施例之二的侧面剖视图 (即图 47中 F-F 剖视图); 图 47是本发明电子锁头实施例之二的正面视图, 也是图 46的 左视图; 图 48是图 46的右视局部剖视图。 在本实施例中, 插芯式电子 锁头的外壳 71和拨轮 73都与普通插芯式机械门锁锁头的葫芦形外壳和 拨轮相似, 并且它的长度和横截面尺寸都参照了市场上通行的插芯式机 械门锁锁头的尺寸。 本实施例包括外壳 71、 本发明智能锁芯装置以及从 动旋转装置。 由图 46, 在本实施例中, 本发明智能锁芯装置的钥匙插孔 单元和圆管 16被设置在外壳 71的空腔内, 本发明智能锁芯装置的转盘 18以及安装在转盘 18上的零部件被设置在外壳 71的一侧。 从动旋转装 置包括从动转盘 76、 轴套 75、 拨轮 73和杯罩 83 ; 从动转盘 76为环状, 它与轴套 75固定在一起并套在圆管 16的外面; 从动转盘 76位于转盘 18和外壳 71之间, 轴套 75穿过外壳与设置在外壳 71缺口中的用于力 传动输出的拨轮 73进行扭力传动的连接; 在从动转盘 76上固定有能够 被本发明智能锁芯装置上的杠杆 22施力而一起转动的驱动挡块 77。 挡 圈 72用于限制本发明智能锁芯装置和从动旋转装置,使它们不会与外壳 71分离; 螺孔 84是安装固定孔。 在图 46中, 有一个碗状的杯罩 83固 定在从动转盘 76上, 在该罩杯 83的外侧设置了一个可以在门内阻止钥 匙开锁的手动开关, 该手动开关包括杠杆 78、 弹片 81和磁铁 82, 杠杆 轴 80固定在杯罩 83外侧的中心, 磁铁 82固定在杠杆 78的一端 (见图 48), 在弹片 81的配合下杠杆 78可以从如图 46所示的位置手动操作到
如图 49所示的位置。在本实施例中, 本发明智能锁芯装置的电路原理图 如图 7所示, 其中, 电磁开关器件 W是干簧管开关或霍尔电子开关, 它 被安装在电子线路单元电路板的中心, 当本实施例上述手动开关的杠杆 78被手动操作到如图 49所示的位置时, 磁铁 82使电路板上的电磁开关 器件 W闭合, 于是, 图 7中晶体管 V2的基极对地短路, 从而可以阻止 钥匙开锁。 本实施例的手动开关与普通机械门锁的门内插销开关功能相 当。
与本实施例配套使用的门锁锁舌机构见图 50和图 51所示,图 51是 图 50的左视图, 在图中, 包含有面板 90、 把手 91和锁舌 94的插芯式 机械门锁的锁舌机构固定在门 92上,在它安装锁头的位置上用本实施例 的插芯式电子锁头替换原来的机械锁头, 本实施例通过螺丝 95和外壳 71上的螺孔 84将其与锁舌机构固定, 本实施例拨轮 73的拨齿落在锁舌 94的齿槽 93中。在图 51的左侧,可以见到作为门内开锁旋钮的杯罩 83 ; 当在门内转动杯罩 83时, 根据图 46的结构以及前述的结构原理可知, 杯罩 83带动从动转盘 76、 轴套 75以及拨轮 73—起转动, 从而带动锁 舌 94移动以实现门内的开锁或上锁。
在手动开关的杠杆 78处于如图 46所示的未被打开的情况下, 当一 把可以开锁的钥匙插入到本实施例钥匙插孔 11中时 (如图 52), 机电驱 动装置在微电脑的控制下驱动杠杆 22, 并使得杠杆 22从原来如图 53或 图 46所示的状态变为如图 52或图 54所示的状态 (图 53是图 46中沿 G-G线的剖视图, 图 54是图 52中沿 H-H线的剖视图), 于是, 杠杆 22 (或力传动离合单元) 就处于可以进行开锁力量传动的状态。 此时转动 钥匙就可以通过杠杆 22的端部将人手开锁的旋转力传递给驱动挡块 77, 于是驱动挡块 77带动从动转盘 76、 轴套 75和拨轮 73—起转动, 从而 实现对锁舌 94的开锁或上锁的移动。 当钥匙被拔出钥匙插孔 11时, 杠 杆 22会在电动复位机构的驱动下被复位到不可传动状态。
在本实施例中, 由于本发明智能锁芯装置上活动柱体 31、 以及外壳 71上滑块 36、 弹簧 38和塞子 37的作用, 使得钥匙只能在转盘 18位于 如图 46或图 53所示的位置才能插入或拔出, 其操作方式与人们在普通 机械锁上的使用习惯相同。
使用本实施例可以立即将原来的机械锁升级为智能电子锁。 本发明电子锁头实施例之三:
将上述本发明电子锁头实施例之二进行改进后得到本实施例, 其改进 的内容为: 1、 本实施例所包含的智能锁芯装置仅使用前述智能锁芯装置 实施例之二; 2、本实施例使用前述智能锁芯装置实施例之二时在顶杆 107 的弯臂 111处加装一段延长杆 115 (经放大后如图 55所示, 图 56是图 55 的左视图, 图 57是图 55的右视图); 3、 本实施例使用前述智能锁芯装置 实施例之二时舍去电子线路单元中的电磁开关器件 W; 4、 本实施例使用 前述智能锁芯装置实施例之二时在电子线路单元的电路板中心作孔, 以便 延长杆 115能从中自由通过; 5、 舍去手动开关中杠杆 78尾部的磁铁 82。
经上述对本发明电子锁头实施例之二进行改进后,本实施例的侧面剖 视图如图 58所示, 其中, 滑动件 101、 扭簧轴 103、 导轨 104、 顶杆弹簧 105、 滑动件弹簧 106、 顶杆 107、 以及电动机 Ml、 电动机 M2、 压线环 28、 开锁驱动丝线 24、 复位驱动丝线 30等按照所在安装位置的投影在图 中表现。 由图 58可见, 顶杆 107加装的延长杆 115穿出电子线路单元 25 的电路板中心孔, 当手动开关所包含的杠杆 78被手动操作到如图 59所示 的位置时, 杠杆 78就成了阻止顶杆 107向内推进的限位挡块, 也就是说, 手动开关被置于阻止钥匙开锁的位置时,它是阻止顶杆 107向内推进的限 位阻挡机构; 在这种情况下, 由于顶杆 107无法向内推进从而导致钥匙无 法完全插到钥匙插孔 11中, 并且导致滑动件 101始终停留在复位的位置, 从而实现了类似于门内插销而阻止钥匙开锁的功能。
本实施例除上述改进以外的其它所有部分的组成和构成形式以及工 作原理都与前述本发明电子锁头实施例之二相同并已在前面叙述,在此不 再赘述。
使用本实施例可以立即将原来的机械锁升级为智能电子锁, 并且更可 靠更安全。
