Description

电子锁具及其控制方法 技术领域
本申请属于锁具技术领域，具体涉及一种电子锁具及其控制方法，尤其适用于电力防误智能锁具及控制。
背景技术
现有技术中，电子锁具一般采用检测开关检测电子锁具闭锁机构的位置来确定锁具的解闭锁状态，但由于产品尺寸误差和/或安装原因导致检测开关检测的锁具状态与锁具的实际状态无法准确对应的情况。特别是对于采用无线供电方式的电子锁具，解闭锁过程中供电及通信中断后，供电中断导致电子锁具并未完成全部解闭锁操作，而通讯中断导致解锁钥匙也并未收到电子锁具的实际状态。当再次进行解闭锁操作时，解锁钥匙无法实现对电子锁具的解闭锁进行精确控制。
此外，现有的电子锁具在采用电机等驱动机构解闭锁时通常需要克服外部部件的阻力，导致驱动机构功耗较高，采用无线供电的方式难以保证长时间高功率的电量输出，会发生因驱动机构供电不足而解闭锁失败的情况。而采用内置电池供电的电子锁具，也会因驱动机构功耗较高而导致电子锁具使用时长减少，需要进行电池维护和更换。
发明内容
为了解决上述无法对电子锁具进行解闭锁精确控制和功耗高的技术问题，本申请的实施例提出了一种电子锁具，在解闭锁机构动作前，通过检测锁钩的小范围移动，去除锁钩弹簧通过锁钩和闭锁弹子施加给解闭锁机构的压紧力，并启动解锁，使得在解闭锁机构动作时，由于没有了锁钩弹子对解闭锁机构的阻力而减小了电机的工作负载，降低电子锁具的功耗，减小部件磨损。
在本申请进一步的实施例中，能够通过获取两个检测部件的状态准确对应锁具的解闭锁状态，从而能够对电子锁具进行解闭锁的精确控制(操作到位)，并可以解决由供电及通信中断导致的电子锁具的解闭锁操作问题，准确记录电子锁具的解闭锁状态。
根据本申请的另一个实施例，还提供了一种电子锁具的控制方法，在电子锁具的解闭锁机构动作前，将锁钩移动到阻力去除位置，解除锁钩对电子锁具的解闭锁机构施加的阻力，随后启动解锁，使得在解闭锁机构动作时，由于没有了锁钩对解闭锁机构的阻力而减小了解闭锁机构的工作负载，降低电子锁具的功耗，减小部件磨损。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图， 对本申请进一步详细说明。但本领域技术人员知晓，本申请并不局限于附图和以下实施例。
本申请实施例提出了一种电子锁具100，如图1a、图1b所示，包括锁体110、锁钩120、解闭锁机构、闭锁弹子140、控制部件170、锁钩弹簧200、解闭锁检测机构、无线供电及通信模块230和第二磁钢。在本实施例中，解闭锁机构可以包括解锁轴130、转轴150、电机160、解锁状态检测开关180和闭锁状态检测开关190，解闭锁检测机构可以包括第一磁钢210和第一霍尔元件220。解锁轴130、闭锁弹子140、转轴150、电机160、控制部件170、解锁状态检测开关180、闭锁状态检测开关190、锁钩弹簧200、第一磁钢210、第一霍尔元件220和无线供电及通信模块230设置在锁体110中，锁钩120可移动的设置在锁体110上，锁钩120设置在锁体110上，在锁钩120的长钩臂和/或短钩臂内侧开设有闭锁槽121，锁钩弹簧200的一端抵接在锁体110上，另一端抵接在锁钩120的长钩臂下侧，朝锁体110外侧向锁钩120施加推力，能够在电子锁具100闭锁状态下将闭锁弹子140压紧在闭锁槽121与解闭锁机构之间；锁钩120在锁具闭锁状态下可在锁钩120动作方向上进行小范围移动，以去除锁钩弹簧200通过锁钩120和闭锁弹子140施加给解闭锁机构的压紧力，解闭锁检测机构检测到锁钩120的小范围移动时，解闭锁机构解除闭锁弹子140对锁钩120的限位。
锁钩120可移动的设置在锁体110上，在锁钩120的长钩臂和/或短钩臂内侧开设有闭锁槽121。在本实施例中，在锁钩120的长钩臂和短钩臂内侧相对的开设有一对闭锁槽121。其中，闭锁槽121具有倾斜向下的下端面。
解锁轴130的侧壁上设置有让位部131，使得解锁轴130侧壁上具有解锁部132和闭锁部133，解锁部132为解锁轴130的让位部131的侧壁，闭锁部133为除解锁部132之外的解锁轴130周向上的侧壁。在本实施例中，如图3所示，解锁轴130的侧壁上相对设置有两个让位部131，让位部131为弧形的让位槽，形成两个解锁部132和两个闭锁部133。在本实施例中，解锁轴130的侧壁上周向等间距均匀设置有两个让位部131，本领域技术人员可以知道，也可以在解锁轴130的侧壁上设置多个让位部131，优选的在周向上等间距均匀设置多个让位部131，每个让位部131在周向上以180度与另一个让位部131相对设置，从而能够与锁具通常设置的两个闭锁弹子140相对应。
闭锁弹子140设置在锁钩120内壁与解锁轴130侧壁之间，能够分别限位在锁钩120的闭锁槽121(图1a)和解锁轴130的让位部131中(图1b)。当电子锁具100处于闭锁状态时，如图1a所示，闭锁弹子140位于解锁轴130的闭锁部133与锁钩120的闭锁槽121之间，解锁轴130的闭锁部133止挡闭锁弹子140的后退路径，闭锁弹子140的一端进入到锁钩120的闭锁槽121的空间中，解锁轴130保持在闭锁位置。其中，锁钩120的闭锁槽121在锁钩 120移动方向上的长度大于闭锁弹子140的高度，以使得锁钩120在锁具闭锁状态下可在锁钩120动作方向上进行小范围移动。当解锁轴130转动一定角度,电子锁具100处于解锁状态时，如图1b所示，解锁轴130的解锁部132转动到闭锁弹子140的后退路径上，闭锁弹子140位于解锁轴130的解锁部132与锁钩120侧壁之间，闭锁弹子140的一端退出锁钩120的闭锁槽121的空间，闭锁弹子140的另一端进入到锁钩120的让位部131的空间中，解锁轴130处于解锁位置。
转轴150可转动地设置在锁体110内，并与解锁轴130驱动连接，解锁轴130可以一体的设置在转轴150上，也可以通过减速机构设置在转轴150上。在转轴150的侧壁上，与解锁轴130的侧壁上的解锁部132对应的设置有第一凸台，与解锁轴130的侧壁上的闭锁部133对应的设置有第二凸台，第一凸台设置在转轴150侧壁的第一高度上，第二凸台设置在转轴150侧壁的第二高度上，第一凸台为一个或多个，第二凸台为一个或多个。优选的，第一凸台对应于解锁轴130的解锁部132的周向中心，第二凸台对应于解锁轴130的闭锁部133周向中心。在本申请实施例中，如图1a、图1b、图3、图4a、图4b所示，两个第一凸台与两个第二凸台在周向方向上交错间隔90°布置在转轴150的侧壁上。
电机160固定设置在锁体110内；电机160的输出轴与转轴150驱动连接，电机160转动可带动转轴150转动。
控制部件170固定设置在锁体110内，可控制电机160转动。
解锁状态检测开关180和闭锁状态检测开关190层叠设置在转轴150的侧部，解锁状态检测开关180与第一凸台对应，闭锁状态检测开关190与第二凸台对应，解锁状态检测开关180和闭锁状态检测开关190分别与控制部件170电连接，用以确定转轴150的转动位置，以确定电子锁具的解闭锁状态。在本申请实施例中，如图1a、图1b、图2、图3、图4a、图4b所示，解锁轴130的侧壁上相对设置有两个让位部131，形成两个解锁部132和两个闭锁部133，两个第一凸台与两个第二凸台在周向方向上交错间隔90°布置在转轴150的侧壁上，层叠设置的解锁状态检测开关180和闭锁状态检测开关190与锁钩120的长钩臂关于转轴150相对设置，因此，当解锁轴130处于解锁位置时，第一凸台触发解锁状态检测开关180，第二凸台与闭锁状态检测开关190错开而不能触发闭锁状态检测开关190，如图4a所示；当解锁轴130处于闭锁位置时，第二凸台触发闭锁状态检测开关190，第一凸台与解锁状态检测开关180错开而不能触发解锁状态检测开关180，如图4b所示。本领域技术人员可以知道，通过改变解锁状态检测开关180和闭锁状态检测开关190与第一凸台和第二凸台对应设置的位置，例如与本申请的上述实施例相比解锁状态检测开关180和闭锁状态检测开关190错开 90°设置，则解锁状态检测开关180能够检测闭锁状态，闭锁状态检测开关190能够检测解锁状态。
在本申请实施例中，如图3所示，解锁轴130的解锁部132包括解锁欠行程区域1321、解锁理论区域1322和解锁超行程区域1323，解锁轴130的闭锁部133包括闭锁欠行程区域1331、闭锁理论区域1332和闭锁超行程区域1333。转轴150旋转，闭锁弹子140位于解锁轴130的解锁部132的解锁理论区域1322时，第一凸台与解锁状态检测开关180对应并触发解锁状态检测开关180。转轴150旋转，闭锁弹子140位于解锁轴130的闭锁部133的闭锁理论区域1332时，第二凸台与闭锁状态检测开关190对应并触发闭锁状态检测开关190。当闭锁弹子140位于解、闭锁欠行程或超行程区域时，第一凸台不与解锁状态检测开关180对应，第二凸台不与闭锁状态检测开关190对应，如图5中的“解锁状态检测开关”和“闭锁状态检测开关”所对应的时序图所示。而对于锁具的实际解闭锁位置，如图5中最下方的“锁具解闭锁位置”所对应的时序所示，闭锁弹子140位于解锁轴130的解锁部132中时，锁具就处于解锁状态，闭锁弹子140位于解锁轴130的闭锁部133中时，锁具就处于闭锁状态。本申请通过将第一凸台对应于解锁轴130的解锁部132的周向中心、第二凸台对应于解锁轴130的闭锁部133周向中心，使得仅在转轴150转动使得闭锁弹子140位于解锁轴的解锁理论区域1322和闭锁理论区域1332时，解锁状态检测开关180或闭锁状态检测开关190才产生触发电平，发送给控制部件170，从而能够精确控制转轴150的转动行程，这对于电子锁具、尤其是无线供电的电子锁具尤为重要，保证在解闭锁状态下，闭锁弹子140位于解闭锁理论区域，此后再次进行解闭锁操作时，转轴150转动规定角度，例如90度，即可实现解闭锁，解决了电子锁具解闭锁位置不准确导致的解闭锁故障(让位部较多情况下容易发生)和零件磨损的问题。
在本申请的上述实施例中，虽然解锁状态检测开关180和闭锁状态检测开关190是层叠设置在转轴150的一侧的，本领域技术人员可以理解，可以根据两个第一凸台和两个第二凸台的位置，在转轴150的两侧相对设置解锁状态检测开关180和闭锁状态检测开关190。
锁钩弹簧200设置在锁体110内，一端抵接在锁体110上，另一端抵接在锁钩120的长钩臂下侧，朝锁体110外侧向锁钩120施加推力。需要说明的是，由于闭锁槽121具有倾斜向下的下端面，在锁具闭锁状态下，闭锁槽121倾斜向下的下端面能够朝向解锁轴130抵压闭锁弹子140，并且当解锁时，解锁轴130转动使得解锁轴130的解锁部132与闭锁槽121相对，锁钩120的闭锁槽121的倾斜向下的下端面挤压闭锁弹子140，闭锁弹子140部分进入让位部131并退出闭锁槽121，锁钩120在锁钩弹簧200的作用下弹出，锁具解锁。可以 替换的，将锁钩弹簧200对应于锁钩120的一端设置为弧面，同样可以实现上述具有倾斜向下的下端面的闭锁槽121的作用。
解闭锁检测机构包括第一磁钢210和第一霍尔元件220，第一霍尔元件220设置在锁体110上，与控制部件170电连接，第一磁钢210固定设置在锁钩120的长钩臂下部；锁钩120在闭锁状态下向下小范围移动时，第一霍尔元件220能够检测到第一磁钢210，以控制启动电机160进行开锁。
电子钥匙可通过无线供电及通信模块230与控制部件170进行通讯及供电。
第二磁钢设于在锁体110内，用于与电子钥匙上的第二霍尔元件相对应，在电子钥匙插入电子锁具时，第二磁钢能够与第二霍尔元件感应，以触发电子钥匙给电子锁具供电以及与电子锁具通信。
本申请实施例提供一种电子锁具的控制方法，使用作为解锁设备的电子钥匙对电子锁具进行解闭锁操作，如图6、图7所示，包括如下步骤：
步骤S10：响应于电子钥匙对电子锁具的接近，电子锁具从电子钥匙接收电能。
在本申请的优选实施例中，电子锁具为无源锁具，电子锁具的工作电能从电子钥匙的电源中获取。可以将电子钥匙插入到电子锁具中，使得电子钥匙的电源与电子锁具有线连接，为电子锁具供电；也可以将电子钥匙插入到电子锁具中或靠近电子锁具，通过感应线圈为电子锁具无线供电。
步骤S20：电子锁具接受电子钥匙的认证，并将电子锁具身份信息发送给电子钥匙。
在本申请的优选实施例中，为了确认电子钥匙与电子锁具进入到正常的通信状态，电子钥匙向电子锁具发送认证命令，电子锁具从电子钥匙接收认证命令并向电子钥匙发送应答信息。
优选的，为了在电子钥匙与电子锁具之间保证通信安全，电子钥匙与电子锁具之间采用加密通信方式，即，电子钥匙向电子锁具发送应用初始秘钥加密的认证命令，电子锁具从电子钥匙接收应用初始秘钥加密的认证命令并生成更新秘钥，电子锁具向电子钥匙发送应用初始同步秘钥加密的应答信息和所生成的更新秘钥。更新秘钥用于电子锁具被成功认证后与电子钥匙之间的通信。需要说明的是，在每次操作中，初始秘钥是电子钥匙和电子锁具在认证过程中使用的秘钥，一旦认证成功后，则电子钥匙与电子锁具使用电子锁具生成的更新秘钥进行后续的通信，从而增强了安全性。
可以在电子锁具被成功认证后，电子锁具将其身份信息发送给电子钥匙；也可以在电子锁具向电子钥匙发送应答信息的同时，电子锁具将其身份信息发送给电子钥匙。优选的，在 电子锁具向电子钥匙发送其身份信息的同时，电子锁具将其解闭锁状态信息发送给电子钥匙。
步骤S30：在认证通过后，响应于基于电子锁具的身份信息确定电子锁具属于可被操作的电子锁具，电子锁具接收电子钥匙发送的解锁或闭锁命令。
在电子锁具被成功认证后，电子钥匙判断所接收到的电子锁具的身份信息是否存在于其自身存储的具有操作权限的电子锁具的ID列表中，以确定其是否对电子锁具具有操作权限。
如果电子钥匙确定其对电子锁具具有操作权限，则根据电子钥匙中存储的对电子锁具的操作指令序列向电子锁具发送解锁或闭锁命令。
电子锁具接收解锁设备发送的解锁或闭锁命令。
其中，当电子钥匙接收到电子锁具的解闭锁状态信息时，则在电子钥匙确定其对电子锁具具有操作权限时，电子钥匙显示电子锁具的解闭锁状态信息，并且电子钥匙根据存储的对电子锁具的操作指令序列和电子锁具的解闭锁状态信息向电子锁具发送解锁或闭锁命令。
例如，在电子钥匙对具有操作权限的电子锁具进行解锁的情况下，当电子锁具为闭锁状态时，电子钥匙向电子锁具发送解锁命令；当电子锁具已为解锁状态时，电子钥匙不再向电子锁具发送解锁命令，而仅在电子钥匙中将电子锁具的状态信息更新为解锁状态；当电子锁具向电子钥匙反馈的解闭锁状态不明确时，即电子锁具为中间态时，例如，在一种情况下电子锁具同时反馈存在未闭锁和未解锁状态，则电子钥匙向电子锁具发送解锁命令。在电子钥匙对具有操作权限的电子锁具进行闭锁的情况下，当电子锁具为解锁状态时，电子钥匙向电子锁具发送闭锁命令；当电子锁具已为闭锁状态时，电子钥匙不再向电子锁具发送闭锁命令，而仅在电子钥匙中将电子锁具的状态信息更新为闭锁状态；当电子锁具向电子钥匙反馈的解闭锁状态不明确时，即电子锁具为中间态时，则电子钥匙向电子锁具发送闭锁命令。
如果电子锁具未被成功认证或者电子钥匙对电子锁具不具有操作权限，则电子钥匙提示异常，并终止操作。
步骤S40：电子锁具响应于锁钩沿与其解锁方向相反的方向移动到阻力去除位置，驱动解闭锁机构对电子锁具进行解锁或闭锁操作，其中，锁钩在其闭锁位置时，锁钩对电子锁具的解闭锁机构施加有阻力；锁钩在阻力去除位置时，锁钩不对电子锁具的解闭锁机构施加阻力。
对于本申请实施例的电子锁具来说，锁钩在闭锁位置会对电子锁具的解闭锁机构施加的阻力，锁钩的解锁方向是锁钩的至少一端脱离锁体的方向，以向上为例。在步骤S40中，通过向下按压锁钩到阻力去除位置，锁钩不再对电子锁具的解闭锁机构施加阻力后，解闭锁机构才对电子锁具进行解锁或闭锁操作，与现有技术中不接触阻力而直接开锁相比，由于去除 锁钩对解闭锁机构的作用力，减小电机/解闭锁机构转动开锁时需要克服的阻力，降低了电子锁具功耗，减小部件磨损。
具体的，在电子锁具响应于锁钩从闭锁位置或解锁位置移动到阻力去除位置，驱动解闭锁机构，例如电机，对电子锁具进行解锁或闭锁操作，电子锁具实时检测电子锁具是否达到相应的解闭锁状态。在电子锁具达到相应的解闭锁状态后，电子锁具解锁或闭锁，电子锁具停止驱动解闭锁机构工作；在规定时间未检测到电子锁具达到相应的解闭锁状态时，这意味着电子锁具存在故障，例如驱动或传输部件卡死，为了保护电子锁具，电子锁具停止驱动解闭锁机构工作。电子锁具将其解闭锁状态信息发送给电子钥匙。电子钥匙根据所接收到的电子锁具的解闭锁状态信息给出相应的操作结果，如电子钥匙进行解锁操作时接收到解锁状态则为“解锁成功”，电子钥匙进行闭锁操作时接收到闭锁状态则为“闭锁成功”，其他情况则为“操作失败”。因此，电子钥匙能够真实记录电子锁具的实际解闭锁状态，并且通过电子钥匙将电子锁具的解闭锁状态实时显示给操作者，能够在对电子锁具的操作过程中指导操作者对电子锁具完全解闭锁(解闭锁到位)。
以下就电子钥匙对本申请实施例的电子锁具进行操作控制方法进行介绍。
当锁钩120位于闭锁位置时，在电子锁具100闭锁状态下，锁钩弹簧200朝锁体110外侧向锁钩120施加推力，闭锁槽121的下端与闭锁弹子140抵接，从而通过闭锁槽121的倾斜向下的下端面或闭锁弹子140在对应于锁钩120的一端设置的弧面，将闭锁弹子140压紧限位在闭锁槽121与解锁轴130的一个解锁部132之间。解锁时，
将电子钥匙插入电子锁具100，电子钥匙的第二霍尔元件感应到电子锁具100内的第二磁钢感应，电子钥匙给电子锁具供电；
电子锁具的控制部件170将电子锁具的身份信息以及解锁状态检测开关180和闭锁状态检测开关190的状态信息发送给电子钥匙；
电子钥匙识别电子锁具的身份信息，对具有操作权限的电子锁具进行解锁；
a.当闭锁状态检测开关190为触发状态(锁具为闭锁状态)时，按压锁钩120，锁钩120克服锁钩弹簧200弹力作用向下小范围移动到阻力去除位置，闭锁槽121的下端与闭锁弹子140分离，锁钩120位于阻力去除位置，锁钩弹簧200不再通过锁钩120和闭锁弹子140向解闭锁机构施加压紧力，并且随着锁钩120的下移，锁体110上的第一霍尔元件220检测到锁钩120上的第一磁钢210，控制部件170根据第一霍尔元件220的检测信号控制电机160进行转动开锁，控制部件170实时获取解锁状态检测开关180和闭锁状态检测开关190的状态变化并发送给电子钥匙。向下按压锁钩120后电机160才执行开锁动作，与直接开锁相比， 去除了锁钩弹簧200通过锁钩120和闭锁弹子140对解锁轴130的作用力，减小电机160/解闭锁机构转动开锁时需要克服的阻力，降低了电子锁具功耗，减小部件磨损。
电机160转动带动转轴150转动，第二凸台不再触发闭锁状态检测开关190，闭锁状态检测开关190断开后，控制部件170获取闭锁状态检测开关190的未触发状态并发送给电子钥匙，电机160继续转动一定角度(电机继续转动的时间大于控制部件170获取闭锁状态检测开关190的未触发状态所需时间)，转轴150的第一凸台触发解锁状态检测开关180，解锁状态检测开关180导通，锁具为解锁状态，控制部件170获取解锁状态检测开关180的触发状态并发送给电子钥匙，控制部件170控制电机160停止转动，即，在一个解锁过程中，解锁状态检测开关180和闭锁状态检测开关190均发生状态改变后，控制部件170控制电机160停止转动，此时，解锁轴130转动一定角度并使解锁部132转动到闭锁弹子140的后退路径上，锁钩弹簧200向开锁方向推动锁钩120，锁钩120的闭锁槽121的倾斜向下的下端面朝向解锁轴130挤压闭锁弹子140，闭锁弹子140部分进入让位部131并退出闭锁槽121，锁钩120可以弹出，使解锁轴130保持在解锁理论区域1322，锁具解锁。
b.当解锁状态检测开关180处于触发状态且闭锁状态检测开关190处于未触发状态时，电子锁具为解锁状态，电机160无需动作，电子钥匙记录锁具状态。
c.当闭锁状态检测开关190和解锁状态检测开关180均处于未触发状态时，闭锁弹子140位于欠行程或超行程区域，按压锁钩120，控制部件170根据第一霍尔元件220的检测信号控制电机160进行开锁，直至控制部件170检测到反馈解锁状态的解锁状态检测开关180处于触发状态且反馈闭锁状态的闭锁状态检测开关190处于未触发状态，控制部件170控制电机160停止转动，锁具解锁，其中，控制部件170实时获取解锁状态检测开关180和闭锁状态检测开关190的状态变化并发送给电子钥匙。需要说明的是，电子锁具的闭锁弹子140位于欠行程区域或超行程区域是由于解闭锁过程中断电(即拔出电子钥匙)导致的。
闭锁时，
将电子钥匙插入电子锁具100，电子钥匙的第二霍尔元件感应到电子锁具100内的第二磁钢感应，电子钥匙给电子锁具供电；
电子锁具的控制部件170将电子锁具的身份信息以及解锁状态检测开关180和闭锁状态检测开关190的状态信息发送给电子钥匙；
电子钥匙识别电子锁具的身份信息，对具有操作权限的电子锁具进行闭锁；
a.当解锁状态检测开关180为触发状态(锁具为解锁状态)时，按压锁钩120，锁钩120克服锁钩弹簧200弹力作用向下移动，锁钩120位于阻力去除位置，锁体110上的第一霍尔 元件220检测到锁钩120上的第一磁钢210，控制部件170根据第一霍尔元件220的检测信号控制电机160进行闭锁，控制部件170实时获取解锁状态检测开关180和闭锁状态检测开关190的状态变化并发送给电子钥匙。
电机160转动带动转轴150转动，第一凸台不再触发解锁状态检测开关180，解锁状态检测开关180断开后，控制部件170获取解锁状态检测开关180的未触发状态并发送给电子钥匙，电机160继续转动一定角度(电机继续转动的时间大于控制部件170获取解锁状态检测开关180的未触发状态所需时间)，转轴150的第二凸台触发闭锁状态检测开关190，闭锁状态检测开关190导通，锁具为闭锁状态，控制部件170获取闭锁状态检测开关190的触发状态并发送给电子钥匙，控制部件170控制电机160停止转动，即，在一个解锁过程中，解锁状态检测开关180和闭锁状态检测开关190均发生状态改变后，控制部件170控制电机160停止转动，此时，解锁轴130转动一定角度并使闭锁部133转动到闭锁弹子140的后退路径上，并将闭锁弹子140的一端压入到锁钩120的闭锁槽121中，闭锁弹子140对应到解锁理论区域1322，电子锁具100闭锁。在电子锁具100闭锁状态下，锁钩弹簧200朝锁体110外侧向锁钩120施加推力，闭锁槽121的下端与闭锁弹子140抵接，从而通过闭锁槽121的倾斜向下的下端面或闭锁弹子140在对应于锁钩120的一端设置的弧面，将闭锁弹子140压紧限位在闭锁槽121与解锁轴130的一个解锁部132之间，以闭锁电子锁具100。
b.当闭锁状态检测开关190处于触发状态且解锁状态检测开关180处于未触发状态时，电子锁具为闭锁状态，电机160无需动作，电子钥匙记录锁具状态。
c.当闭锁状态检测开关190和解锁状态检测开关180均处于未触发状态时，闭锁弹子140位于欠行程或超行程区域，按压锁钩120，控制部件170根据第一霍尔元件220的检测信号控制电机160进行闭锁，直至控制部件170检测到反馈闭锁状态的闭锁状态检测开关190处于触发状态且反馈解锁状态的解锁状态检测开关180处于未触发状态，控制部件170控制电机160停止转动，锁具闭锁。
在本申请的上述实施例中，作为检测部件的解锁状态检测开关180和闭锁状态检测开关190优选为微动开关，被检测部件为第一凸台和第二凸台。本领域技术人员可以理解，可以选用霍尔元件作为检测部件，磁钢作为被检测部件；或者，干簧管作为检测部件，磁性构件作为被检测部件，等。此外，本申请中的锁具不限于挂锁，电机可以正转和反转。
