Description

电子密码锁输入装置、 输入方法及其应用 发明领域
本发明涉及电子密码锁， 尤其涉及电子密码锁输入装置、 用于电子密码锁的输入 方法以及该电子密码锁输入装置的应用。 背景技术
已有的机械转盘式密码锁密码的开启和设置是通过密码锁内部的机械联动机 构实现的。 这种密码锁的密码开启和密码设置需要准确定位， 尤其是更改密码比 较复杂， 除了需要拆开锁具外， 未经专业训练的人很难完成设码操作。 此外， 该 方法的密钥量取决于机械联动机构内部转向轮的数量。 要获得大的密钥量， 必须 增加转向轮的数量， 这样会增大结构的体积和复杂性。 因此， 人们越来越多地尝 试使用操作方便、 结构紧凑的电子密码锁。
在美国专利 US6420958 中就公开了一种电子数码锁， 它使用与一个步进电机结合 的转盘， 转动转盘， 步进电机发出电信号， 该信号经过整形电路， 输出到微计算机进行 计数处理， 并由显示装置显示。 当转盘停止转动， 将所显示的数字作为密码组合的一部 分输入。 由于步进电机结构复杂， 价格较高， 此外还需要如波形整形电路等外围电路， 所以这种电子数码锁的制造成本相对较高。
另外， 在美国专利 US4745784和 US4899562中也分别披露了一种转盘式电子密码 锁输入装置， 它们的结构相似。 该密码锁输入装置包括一个转盘、一个固定在转盘内随 转盘在一起转动的触头、与该触头位移轨迹相对应的呈圆周形或半圆周形分布且与一电 路板连接的 10个触点， 当转盘转动到某一刻度位置， 轴向推压转盘， 其上的触头便与 该刻度位置对应的某个触点接触产生一个电信号。每一个触点的电信号对应一个不同的 数， 该数作为密码的一个元素被确认。
在日本专利 P2000-73632 中又公开了一种转盘式电子密码锁输入装置， 它包括一 个固定在转盘上的导电片、与该导电片接触的两组呈圆周断续分布的触点群、以及与触 点群电连接并向其供电的的导电环。当转盘转动时，导电片将上述两组触点群断续接触 接通，从该两组触点群的引出线可获得两组电脉冲信号，对该信号进行处理并作为密码 元素显示。 在该技术方案中， 密码的确认装置是一个安装在转盘上的按钮开关。
上述三种电子密码锁输入装置均采用电接触方式直接产生表示密码的电信号， 因 而存在接触可靠性的问题。特别在日本专利 P2000-73632的电子密码锁输入装置中，还 存在因摩擦接触而产生的磨损问题。此外由于表示密码的电信号是直接引入的，它没有 经过隔离， 因此， 在安全防范性上也存在不足。 此外， 已有的密码门锁多为数字键盘式， 大多数情况下， 键盘安装在门锁执手上 方的锁体面板上。而美国专利 US6378344中所公开的一种密码锁执手，则将一个数字键 盘镶嵌在锁具执手上，通过该键盘输入密码。 由于键盘平面尺寸较大， 使得该执手体积 较普通执手大许多， 使用该执手时， 会产生不适感。
已有的箱包密码锁多为机械滚轮式， 如前所述地， 机械式密码锁结构复杂， 使用 不够方便。 如在中国专利 ZL00261865. 6所公开的用于箱包的机械号码锁， 尽管有 4个 号码轮， 并采用了新的结构， 使密码更换操作得以简化， 但仍存在密匙量小、调换密码 仍需较复杂的机械操作的缺点。 发明内容

以下结合几个具体的实施例， 对本发明的电子密码锁输入装置、 输入方法及其应 用作进一步的说明。 电子密码锁输入装置
图 1示出的是根据本发明第一个实施例的电子密码锁输入装置。 如图所示， 该电 子密码锁输入装置由信号装置 2、 测控装置 3、 显示装置 4以及确认装置 5组成。
信号装置 2可以采用机电式旋转编码器， 该编码器转子与转盘有确定的机械传动 关系并随转盘转动。编码器有两个编码信号输出端， 转盘顺时针转动时，第一个输出端 输出电脉冲信号 11在先； 转盘逆时针转动时， 第二个输出端输出电脉冲信号 12在先。 两组电脉冲信号中包含的脉冲个数与编码器转子转过的角度成正比例关系，脉冲信号的 频率与编码器转子转动速率成正比例关系。
测控装置 3由单片计算机及其外围电路组成，可以采用内部可以集成有 RAM和 ROM 的单片机， 用于测量信号装置 2所输出的电脉冲信号 1 1和 12， 对该电脉冲信号次 序进行判定并做相应运算， 以将该信号转换成包含密码元素在内的字符序列， 以 及判定是否确认输入当前密码元素和进一步判定是否所有的密码元素都输入完 毕。 ROM存储控制程序和预置的数字信息， RAM存储测试数据、 显示数据以及其它中间 数据等数字信息； E2PR0M需另行设置， 在 E2PR0M中存储事先设定好的开锁密码、 设置 密码和验证密码。 在单片机中包含有若干个 I/O端口 P2〜P6， 其中， 测控装置 3通过 端口 P2和 P3接收信号装置 2转换的两组电脉冲信号 11和 12， 端口 P6连接于确认装 置 5， 端口 P4连接于显示装置 4， 端口 P5可选择地连接于电子密码锁的执行装置 7。
如图 1所示， 为了更好地实现本发明的技术效果， 本实施例中的确认装置 5 为一个开关装置， 开关装置 5的闭合受转盘轴向运动的控制， 当转盘未被揿按， 开关装置 5处在断开状态， 当转盘被揿按后， 开关装置 5闭合， 该闭合动作在开 关装置 5的两端产生一个电信号 13， 该信号引入测控装置 3的 I/O端口 P6作为输 入密码的一个元素被输入的确认信号。
另外， 在图 1的电子密码锁输入装置中， 每当开关装置 5产生一个电信号从 而开始一个给定的计时周期期间， 测控装置 3便对该计时周期是否结束进行判定， 若计时周期结束， 则判定输入超时。
显示装置 4在测控装置 3的驱动下以滚动刷新方式显示所述字符序列以及预制 提示信息。 其中的预置信息用符号表示， 可参见图 6， 挂锁形状符号指示锁闭合和 打开状态， 时钟形状符号指示定时开锁或延时开锁时间， 钥匙形状符号指示设码 状态， 电池形状符号指示低电池电量， 其余圆点符号指示各部分密码依次确认状 态。
以下将结合图 2详细描述本发明电子密码锁输入装置的工作原理和流程， 它们可 以通过 ROM中存储的程序来实现。
如图 2所示， 在步骤 S21， 信号装置 2随转盘的转动而转动， 产生电脉冲信号 11 和 12 ,这两组信号引入测控装置 3的 I/O端口 P2和 P3，无论转盘朝哪个方向转动都会 将测控装置 3从微功耗状态唤醒， 使其转入工作状态， 进而使显示装置 4上电。 此后， 测控装置 3的 I/O端口 P2和 P3开始接收到第一组电脉冲信号 11和第二组电脉冲信号 12， 测控装置 3在程序控制下进入计时周期， 计时程序从零开始计时。 同时， 整个电子 密码锁的输入流程进入步骤 S22。
如图所示， 在步骤 S22 , 测控装置 3测量所接收到的电脉冲信号 11和电脉冲信号 12。 接着， 在步骤 S23， 测控装置 3对电脉冲信号 11和 12的先后次序进行判定。 若电 脉冲信号 11在先， 则将当前所测得的脉冲数变化量与之前所测得的脉冲数的累计和进 行加法运算； 若电信号 12在先， 则将当前所测得的脉冲数的变化量与之前所测得的脉 冲数累计和进行减法运算。 接下来， 在步骤 S24和 S25， 测控装置 3将上述运算结果经 数据处理后通过 I/O端口 P4驱动显示装置 4以十进制数字显示， 并按所测得的电信号 脉冲频率依比例关系调整上述运算结果的显示刷新速率， 同时流程进入步骤 S26。
在步骤 S26 , 测控装置 3先检测 I/O端口 P6是否有输入信号， 若没有测得开关装 置 5输出的电平信号 13， 测控装置 3随即在步骤 S27检测超时计时程序所计时间是否 己到。 若超时计时程序所计时间还没到， 则转至步骤 S22。 若超时计时程序所计时间已 到， 则进入步骤 S32 , 给出超时报警信号同时由显示装置 4显示输入超时信息。 若测控 装置 3测得开关装置 5输出的电平信号 13， 则将当前显示装置 4显示的密码元素予以 确认并存入 RAM后，通过 I/O端口 P4驱动显示装置 4显示密码接收确认信息，同时流程 转至步骤 S28， 进入新的计时周期。
在步骤 S29，测控装置 3对已确认接收的密码元素进行计数，将计数结果与预先设 定的数相比较， 如果计数结果小于设定数， 进入步骤 S30。 在步骤 S30, 测控装置 3将 当前显示的数字作为密码元素存入 RAM, 并在接下来的步骤 S31， 驱动显示装置 4显示 密码输入确认信息， 同时流程回到步骤 S22。 如果计数结果等于设定数， 则确认一组完 整的密码接收完毕， 同时流程转至 S33。 在步骤 S33 , 测控装置 3对己输入并确认的若 干个密码元素进行顺序拼接操作后， 再存入 RAM, 通过 I/O端口 P4驱动显示装置 4显 示密码接收完毕信息。此时， 电子密码锁的输入流程全部结束， 可以根据需要选择性地 从步骤 S34进入到电子密码锁的其它工作流程。
比如， 密码设置可以通过上述输入密码的方法步骤， 先输入预先设置的密码， 使 本发明的电子密码锁输入装置进入密码设置状态， 然后在该状态下输入新的开锁密码， 旧的密码被替代， 以后使用新密码开锁。 具体可参见图 2。 在步骤 S34， 从 E2PR0M中读 取预先设定的开锁密码和设置密码，并与输入的密码进行比较。接着在步骤 S35判定输 入密码是否与开锁密码相同。 若相同， 则进入步骤 S36, 向执行装置 7发出开锁指令， 此后在步骤 S37由执行装置 7打开闭锁装置。 若在步骤 S35判定不相同， 则进入步骤 S38 , 判定输入密码与预设的密码是否相同。 若相同， 则转入密码设置流程， 反之则可 以在步骤 S39由显示装置 4显示密码错误信息。 转盘式电子密码锁输入装置
本发明的电子密码锁输入装置还可以根据需要特别制作成转盘式的， 正如发 明的第二个较佳实施例所示。 如图 3所示， 当制作成转盘式电子密码锁输入装置 时， 信号装置 2包含： 一面板体 1 11， 一装面板体 111上的自由转动的转盘 101， 一固定在转盘 101中心的传动轴 102， 一套装在传动轴 102上的主动齿轮 103， 一 与主动齿轮 103啮合的从动齿轮 115， 以及一与从动齿轮 115同轴连接的旋转编码 器 108 ; 测控装置 3为一被编程的微控制器（以下简称 MCU)106; 显示装置 4为一 信息显示屏 110; 开关装置 5为一光电开关 107。
在上图中， MCU106、编码器 108、信息显示屏 110和光电开关 107设置在一块电路 板 109上，电路板 109则设置在面板体 111内。编码器 108可以采用机电式旋转编码器。 光电开关 107采用红外线光电开关，它包括一个发射管和一个接收管。微控制器采用带 ROM和 RAM以及若千个 I/O口的单片微计算机， 在 ROM中装有控制程序。 MCU上的 I/O 口分别与编码器 108、光电开关 107以及信息 示屏 110连接， 其中的一个 I/O口与密 码锁的密码识别装置连接， 用于数据通讯。
转盘 101、 传动轴 102、 主动齿轮 103、 从动齿轮 115以及编码器 108的转子构成 一简单传动系统。 具体说， 传动轴 102的截面呈正多边形， 一端固定在转盘 101中心， 主动齿轮 103设有一个配合传动轴 102另一端插入的正多边形内孔。主动齿轮 103—侧 的圆柱面与面板体 U 1对应内孔动配合。从动齿轮 107与主动齿轮 115啮合，从动齿轮 115的两个圆柱面分别与齿轮压板 117内孔和面板体 111的另一内孔动配合，齿轮压板 117卡设在面板体 111的两个支撑柱上， 从动齿轮 115的轴伸的截面为正多边形， 该轴 伸作为编码器 108的转子的传动轴装入编码器 108转子的正多边形内孔中。在这个传动 系统中面板体 111、 齿轮压板 117等所起的作用是支承和定位。
转盘 101和传动轴 102可轴向位移 2至 4毫米， 传动轴 102非固定端开有一轴向 内孔 122, 孔内设有一复位弹簧 104。 面板体 111上开有两个与光电开关 107的发射管 和接收管相对应的孔槽 118。
图 5示出了本发明第二个实施例中转盘的结构。 如图所示， 转盘 101的内沿有一 圆周形裙边 123， 该裙边对应于电路板 109上的光电开关 107的发射管和接收管之间。 当转盘 101被揿压时，裙边 123将光电开关 107的光信号阻断，光电开关输出的电信号 发生变化， 该电信号传递给 MCU106， 当 MCU106监测到该信号变化后， 将当前显示的数 字作为密码的一部分予以确认和保存。 揿压转盘 101 的外力撤销后， 在复位弹簧 104 的复位作用下， 转盘 101和传动轴 102复位。
主动齿轮 103的形状如图 4所示，其内端面的同心圆平面齿槽 121与钢珠 114、弹 簧 113以及面板体 111上的对应盲孔组成一个简单机构。钢珠 114在弹簧 113的压力作 用下与主动齿轮 103的同心圆平面齿槽 121接触配合，其作用是在转动转盘 101的过程 中， 随着显示数字的动态变化， 产生与数字显示刷新同步的手感。
信息显示屏 110设有一个显示提示信息符号的八段数码管和两个显示数字的七段 数码管， 如图 6所示， 其中挂锁形状符号指示锁闭合和打开状态， 时钟形状符号指示定 时开锁或延时开锁时间， 钥匙形状符号指示设码状态， 电池形状符号指示低电池电量， 其余圆点符号指示各部分密码依次确认状态。
信息显示屏 110的显示面为一倾斜面， 其倾角度使得操作时使用者视线与信息显 示屏 110的显示面接近垂直， 以符合人体工程学原理。与之对应的面板体的显示窗口所 在平面，也为同角度的倾斜面。透明窗盖 116卡设于所述面板体的显示窗口所在的平面 上。
面板体 111的上部和下部各隆起为耳状沿 105，起执手作用，耳状沿 105的内面 (背 部）设有与手指吻合的凹槽， 便于开门操作。 此外， 面板体显示窗口面一侧开有一异性 导向孔 112， 用于机械应急钥匙的插入。
装配时， 电路板 109固定在面板体 111的另一侧， 主动齿轮 103的圆柱面装入面 板体 111的对应内孔中， 与主动齿轮 103啮合的从动齿轮 115—端圆柱面装入面板体 11 1的对应孔， 其轴伸插入编码器 108的转子内孔中， 齿轮压板 117的中孔与从动齿轮 1 15的另一端圆柱面配合，齿轮压板 117由面板体 111上的两个支撑柱卡紧，钢珠 114、 弹簧 113装入面板体 111的对应孔内，传动轴 102插入主动齿轮 103的多边形内孔，其 轴向内孔中的复位弹簧 104的另一端由保险箱门面限位，转盘 101内沿的圆周形裙边通 过面板体 111的两个孔槽与光电开关 107的发射管和接收管相对应。
下面对本实施例的转盘式电子密码锁输入装置的具体应用进行说明。
当需要开锁时，转动转盘 101， 当显示的两位数与预先设定的开锁密码的第一部分 相同时， 停止转动并轴向揿压一下转盘 101， 此时信息显示屏 110半圆周分布的最下方 的圆形符号被点亮，表示密码的第一部分被确认输入，按同样方式输入密码的其它部分， 在密码的每一部分被确认输入过程中，信息显示屏 no半圆周分布的圆形符号被依次点 亮， 当密码的最后一部分输入后， MCU106 将所输入的完整密码传送至密码锁的密码识 别装置， 密码识别装置对接收到的密码进行识别和判定， 若密码判定结果正确， 密码识 别装置控制电动驱动装置打开锁具， 并传送幵锁信号至 MCU106, 后者收到开锁信号后， 控制信息显示屏 110上的挂锁形状符号点亮。
需要重新设置开锁密码时， 首先通过上述密码输入和确认步骤输入设置密码， 当 输入的设置密码被判定正确后， 钥匙形状符号被点亮， 表示进入了密码设置状态， 此时 可输入新的开锁密码。
当密码锁电源电压被 MCU106测定为低于规定值时， 则干电池形状符号被点亮， 提 示需要更换电池。 滚轮式电子密码锁输入装置
本发明的电子密码锁输入装置也可以根据需要特别制作成滚轮式的， 正如发 明的第三个较佳实施例所示。如图 7所示， 当制作成滚轮式电子密码锁输入装置时， 信号装置 2为一滚轮装置 201 (图 7虚线框内部分)， 它包括： 滚轮 202 , 与滚轮 202同 轴的编码器 212， 以及用于支承滚轮 202的弹性支架 204; 测控装置 3为一被编程的 微控制器 208; 显示装置 4为一信息显示屏 209; 开关装置 5为一设置在滚轮 202轴伸 下的微动开关 206。 微控制器 208分别与编码器、 信息显示屏 209以及微动开关 206 电连接。
旋转编码器可以采用光电编码器件， 它由光电转轮 203、 安置在光电转轮两侧 的发光二极管和光敏三极管 207组成。
微控制器 208由单片计算机 MCU、 存储器 RAM以及外围电路组成。 MCU中 固化有控制程序， MCU的若干个 I/O口分别与滚轮装置 201和信息显示屏 209电连 接， 其中的另一个 I/O口与密码锁的密码识别装置电连接， 以进行数据通讯。
此外， 可以在电路板 21 1上设置接插件 210， 使该 MCU可以通过接插件 210与 密码锁密码识别装置以及电源相连接。
滚轮装置 201、 微控制器 208、 信息显示屏 209和微动开关 206可以如图所示地 装在同一块电路板 21 1上。 也可以如图 8所示， 将信息显示屏 209和微控制器 208装 在一块电路板 214上， 而将滚轮装置 201和微动开关 206装在另一块电路板 217上， 以适用不同的安装条件。 在电路板 214上也可以如图 7所示地设置接插件 210， 且同 时在电路板 217上也可以设置接插件 215和 216， 接插件 215和 216之间可通过导线 213进行连接。 本领域技术人员应该明白， 这两种安装形式所起到的技术效果是相 同的。
回到图 7， 在滚轮装置 201中， 滚轮 202的转动方向和转过的角度通过光电转轮 203和发光二极管及光敏三级管 207被转换为电脉冲信号， 该信号引入微控制器 208 中 MCU的 I/O口，经 MCU程序处理后控制信息显示屏 209以滚动方式显示数字 0-9。 当揿压滚轮装置 201时， 同时便致动安置在其轴伸 205下的微动开关 206， 微动开关 206被致动后产生的电信号作为密码元素输入确认信号引入 MCU的另一个 I/O口， 经 MCU程序判定后， 微控制器 208控制信息显示屏 209停止显示滚动， 并将当前显 示的数字确认为密码的一部分。
在本实施例的滚轮式电子密码锁输入装置中， 信息显示屏 209可以采用定制的数 码管或液晶显示屏。如图 7所示，其显示内容及功能与第二个实施例的转盘式密码锁输 入装置相同， 只是显示数字的位数和图形符号的排列与布置有所不同。
图 9和图 10分别示出了弹性支架 204在两种状态下的放大剖视图。 这两个弹性 支架 204的结构基本相同。
如图 9所示， 弹性支架 204由底座 225、 复位弹簧 227、 Y型支架 220组成， 其中 Y型支架 220顶部设有与轴配合的圆形轴槽 221 ,轴槽 221的开口 222的尺寸稍小于轴 径， 装入轴时需将幵口稍撑开一点， 轴装入后径向位移被开口限制， 但可自如转 动， 滚轮 202两端设有肩， 与轴槽 221配合， 以限制滚轮 202的轴向位移。 底座 225 固定在电路板 21 1上， 复位弹簧 227和 Y型支架 220装入底座 225 , Y型支架 220与底 座 225配合的柱面下部设有两个卡钩 224， 底座 225与 Y型支架 220配合的孔上开有 使 Y型支架 220和卡钩 224顺利通过的两个滑槽 226以及与滑槽 226相差 90度设置的 两个卡槽 228(在图 10中）。
如图 10所示， Y型支架 220及其卡钩 224沿滑槽 226插入底座孔， 到底后， 将 Υ · 型支架 220旋转 90度使卡钩 224与卡槽 228对准， 在复位弹簧 227作用下， 卡钩 224向 上位移并卡入卡槽 228内。 如此， 将 Υ型支架 220固定。
当滚轮 202被揿压后， Υ型支架 220沿卡槽 228下移 1-2毫米， 滚轮 202的一端轴 伸 205便可致动设置在其下的微动开关 206。 当揿压撤消后， 复位弹簧 227使 Υ型支 架 220复位。
另外， 若要在滚轮 202转动过程中产生棘轮的效果， 有两种方案： 一是将滚轮 202的一个端面制成波纹形状， 在靠近滚轮 202波紋端面的一个底座 225上装一棘轮 式弹簧 (图中未示出）， 该弹簧一端被底座 225上设置的槽与孔固定， 弹簧另一端弯 成一圆形并与滚轮 202波纹形状端面弹性接触， 滚轮 202转动时便可产生棘轮的手 感。 二是在 Υ型支架 220上设一盲孔 (图中未示出）， 内装一弹簧和一钢珠， 在与 Υ 型支架 220配合的滚轮轴的一段表面制成齿状， 钢珠在弹簧作用下与该齿接触配 合， 同样可以在滚轮 202转动时产生棘轮的手感。
较佳地， 还可以在电路板 21 1上安装一蜂鸣器， 它与信息显示屏 209配合， 一 起发出提示信息。
以下将对上述滚轮密码锁组件的使用进行说明。
当需要开锁时， 转动滚轮 202， 信息显示屏 209随滚轮 202的转动滚动显示数字 0-9， 数字滚动的次序 （升序或降序） 与滚轮转动的方向 （顺时针或逆时针）对应。 当显示的当前一位数字与预先设定的开锁密码的第一元素相同时， 停止转动并轴 向揿压一下滚轮 202。 此时信息显示屏 209上的第一个圆形符号被点亮， 表示密码 的第一位被确认输入。 按同样的方式输入密码的其它位， 在密码的每一位被确认 输入过程中， 信息显示屏 209的圆形符号被依次点亮。
当密码的最后一位输入后， 如果所输入的密码完全正确， 则挂锁形状符号点 亮， 表示锁已打开。
如果输入的密码错误， 则信息显示屏 209和蜂鸣器 (如果安装的话)会给出提示 信息， 程序进入出错处理流程。
如果需要启用定时开锁或延时开锁功能， 则可通过输入特定的密码， 进入定 时或延时设置状态， 输入时间后， 该功能便被启用。
需要重新设置开锁密码时， 首先通过上述密码输入和确认步骤输入设置密码， 当输入的设置密码被判定正确后， 钥匙形状符号被点亮， 表示进入了密码设置状 态， 此时可输入新的幵锁密码。
当密码锁电源电压低于规定值， 则干电池形状符号被点亮， 提示需要更换电 池。 密码锁执手
当将上述滚轮式电子密码锁输入装置应用于门锁执手后， 构成一种新颖的密 码锁执手。 图 1 1就示出了这样一种密码锁执手的外部结构。
如图所示， 其中的执手体 301为空心的， 在该空腔内设置前述的滚轮式电子密 码锁输入装置。 该滚轮式电子密码锁输入装置采用图 7所示的形式， 将滚轮装置 201、 微控制器 208、 信息显示屏 209和微动开关 206均安装在同一块电路板 21 1上， 然后可以釆用螺钉将电路板 21 1固定于执手空腔内。 在执手正表面开有第一窗口 302， 它对应滚轮 202从而可方便地拨动和揿压滚轮。 同样地再在该执手正表面开 设第二窗口 303， 它对应信息显示屏 209， 从而可方便清晰地观察信息显示屏 209所 显示的内容。
为了更加清楚地描述上述密码锁执手的内部结构， 图 12和图 13示出了图 1 1所 示密码锁执手的剖面结构。
如图 12所示， 密码锁执手还包括一转动轴 304， 它固定于执手体 301内。 由图 13可知， 在转动轴 304内设有使连接导线穿过的通孔 305。 所安装的滚轮式电子密 码锁输入装置可以通过接插件 210和导线 218与安装于锁芯机构内或安装于门内其 它位置的密码锁密码识别装置以及电源相连接。
图 14所示的是另一种密码锁执手的外部结构。 它由执手体 401、 面板 402和透 明窗盖 403构成。 图 15示出了该密码锁执手的剖面结构。 由图可知， 在执手体 401 上设有一镂空区域 405，其尺寸和形状与面板 402相配合，从而正好将面板 402嵌入， 面板 402的外表面与执手体 401的外表曲面光滑吻合。 面板 402和执手体 401可以釆 用公知的卡扣结构固定。 从图中还可以看出， 滚轮式电子密码锁输入装置采用图 8 所示的形式， 即使用了两块电路板， 其中在电路板 214上安装微控制器 208和信息 显示屏 209， 在电路板 217上安装滚轮装置 201和微动开关 206， 这两块电路板之间 通过接插件 215和 216以及导线 213相连接。 电路板 214和 217安装于面板 402内， 其 固定方式可以采用公知的卡扣结构， 也可以采用螺钉螺孔结构。 在面板 402上设置 第一窗口， 其尺寸和位置与滚轮 202相配， 从而可露出滚轮 202的一部分， 以便于 手指拨动和揿压。 类似地在面板 402上设置第二窗口， 其尺寸和位置与信息显示屏 209相配， 从而可方便清晰地观察信息显示屏 209所显示的内容。 透明窗盖 403卡设 于第二窗口所在平面上， 以便操作时观察显示的密码和信息。 执手体 401还包括一 固定在其中的转动轴 404，在转动轴 404内设一通孔，可使连接导线 215穿过该通孔， 将滚轮式电子密码锁输入装置与安装于门内的密码锁密码识别装置以及电源相连 接。
图 16所示的是还有一种密码锁执手， 它由执手体 501、 执手底座 502和面板 504 组成。 结合示出其内部结构的图 15可知， 滚轮式电子密码锁输入装置采用图 8所示 的形式， 由两块电路板组成， 电路板 214上装有信息显示屏 209和微控制器 208， 该 电路板 214固定在底座 502内， 电路板 217上装有滚轮装置 201和微动开关 206， 该电 路板 217固定在面板 504内， 两块电路板通过接插件 215和 216以及导线 213相连接。 底座 502为一圆柱形罩壳， 其正面开有一个使信息显示屏 209所显示内容得以观察 的第二窗口 505。 在面板 504表面开设第一窗口， 其尺寸和位置与滚轮 202相配， 从 而可露出滚轮 202的一部分， 以便于手指拨动和揿压。 执手体 501为空心， 其正面 设有与面板 504形状相配合的空腔， 面板 504卡设于空腔内沿。 在执手体 501内还有 一转动轴 506， 在转动轴 506内设置通孔 507和 508， 可使连接导线 218穿过通孔 507 和 508， 从而将滚轮式电子密码锁输入装置与安装于门内的密码锁密码识别装置以 及电源相连接。
上述三种密码锁执手的转动轴与密码锁的锁心机构或离合装置结合， 锁心机 构或离合装置由密码锁的电动执行机构驱动， 电动执行机构由密码锁密码识别装 置控制， 密码锁密码识别装置与滚轮式电子密码锁输入装置电连接并进行数据通 讯。 在正确的开锁密码输入之前， 锁心机构或离合装置与密码锁执手 (简称执手） 分离， 此时执手不能被转动， 与之联动的锁舌处于伸出状态。 按照本发明电子密 码锁的输入方法输入正确的开锁密码后， 密码识别装置控制电动执行机构动作， 锁心机构或离合装置与执手结合， 此时将执手向下转动一个角度 （不超过 90度） ， 锁舌被缩进锁体， 锁即被打开。 箱包密码锁面板
