Description

一种基于NB-IOT的低功耗挂锁 技术领域
本实用新型涉及挂锁领域，特别是一种基于NB-IOT的低功耗挂锁。
背景技术
现今的挂锁均为纯机械结构，通过将锁梁插接到锁体内，同时第二锁舌插接入锁梁内，使锁梁无法自动弹出锁壳外，达到锁合的目的；纯机械的挂锁还不能实时检测锁具的状态，在锁合时，如果仅仅是将锁梁插入锁体内，而由于插入深度不够，第二锁舌并未插入锁梁内，此时挂锁并未锁合，而用户也并不知晓，一旦用户离开就会造成较大安全隐患。
请参见图1，公布号为CN109736643A的中国发明专利公开了一种带有闭锁检测部件的挂锁，其特征在于，包括锁体1、U形锁梁、CPU3(相当于控制模块)、闭锁检测部件4(相当于开锁检测开关)和NB-IOT模块5，U形锁梁右端插入锁体1内，U形锁梁左端底部设有开锁弹簧21，以使U形锁梁左端随开锁弹簧21的伸缩在锁体1内上下移动；其中，闭锁检测部件4包括霍尔传感器41和永磁42，霍尔传感器41固连在锁体1内，霍尔传感器41与CPU3电性连接，永磁42固连在U形锁梁左端一侧，U形锁梁两端同时插入锁体1内，永磁42与霍尔传感器41位于同一水平面上，以使霍尔传感器41产生闭锁信号并传输到CPU3；NB-IOT模块5与CPU3电性连接，以使CPU3将处理后的闭锁信号传输到手机APP上；锁体1外侧端面上贴有二维码，以使手机扫码后将开锁信号通过NB-IOT模块5传输到CPU3。

锁体1还设有一端位于插孔11内的传动部4a、传动部4a另一端朝向活动执行部41延伸，当锁梁2处于锁定状态时，插头21通过挤压传动部4a挤压活动执行部41使开锁检测开关4断开，传动部4a与锁体1之间具有复位弹簧4b，复位弹簧4b用于保持传动部4a离开活动执行部41。
开锁检测开关4为自动复位的常闭行程检测开关，控制模块3设置在主电路板200上，开锁检测开关4与主电路板200固定连接且开锁检测开关4设置在插孔11下方。锁梁2为U形锁梁，在其他实施例中为柔性锁梁。
请参见图11-13，在本实用新型第二实施例的基于NB-IOT的低功耗挂锁中，通过机械锁芯85代替电子锁芯8，插入对应的钥匙转动机械锁芯85从而转动主动齿，使转动柱102从凸出部分101a朝向钢球101的锁定位置转动到缺口部分101b朝向钢球101的解锁位置，以允许钢球101与配合凹陷20完全分离。
开锁检测开关4可设置于插孔11的侧边，开锁检测开关4的活动执行部41转动连接于开锁检测开关4上，当锁梁2处于锁定状态时，插头21挤压活动执行部41向下转动使开锁检测开关4断开，NB-IOT模块5断电，插头21脱离插孔11时开锁检测开关4闭合，电池6向NB-IOT模块5供电，向接收装置100发送锁具状态信息。
本实用新型中，开锁检测开关具有自动复位的活动执行部，当锁梁处于锁定状态时，插头挤压活动执行部使开锁检测开关断开，NB-IOT模块断电，插头脱离插孔时开锁检测开关闭合，电池向NB-IOT模块供电，发出报警和/或向接收装置发送锁具状态信息以提醒使用者。
在本实用新型中，拨头的侧面设置了激发器使电机驱动拨头在解锁后继续旋转到初始位置时能够掉电，只需要在解锁时参与工作，减小电机和电池的损耗，延长了使用寿命。
以上，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，虽然本实用新型已以较佳实施例揭露如上，然而并非用以限定本实用新型，任何熟悉本专业的技术人员，在不脱离本实用新型技术方案范围内，当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是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、等同变化和修饰，均仍属于本实用新型技术方案的范围内。
