相关申请的交叉引用
本公开要求于2019年5月14日向中国国家知识产权局递交的中国专利申请201910401181.1的权益，该申请的公开内容通过引用整体并入本公开中。
技术领域
本公开涉及物流监管领域，具体地涉及一种智能锁。
背景技术
在物流运输或海关通关查验等领域中，需要防止所运输的或待查验的货厢(例如，集装箱)在未经允许的情况下被非法打开，从而保证货厢运输的安全性并保障海关通关查验的监管作用，不给不法分子可乘之机。因此，用于锁闭货厢的锁具需要具备高的安全可靠性。另一方面，锁具还需要操作方便，并且能够适用于不同型号/尺寸货厢的锁闭要求。
传统锁具通常采用锁体和锁绳相互配合的结构，闭锁时将锁绳插入锁体的锁孔中，而开锁时则将锁绳从锁体的锁孔中拔出。传统锁具中，锁绳长度固定且不能调节，不能同时适用于不同型号/尺寸货厢的锁闭要求。而且，锁绳和锁体之间的配合只能通过单方向插拔操作来实现，限制了锁具使用的灵活度。
此外，有些用于锁闭货厢的智能锁具通过采用行程开关或霍尔器件等辅助器件来判断锁舌(或锁杆)在锁体(或锁孔)中的位置和/或行程，以确认锁具的开锁/锁闭状态。然而，实践中，在这些智能锁中，行程开关等辅助器件体积相对较大，安装不便。并且，有时容易受外界环境的影响，使用寿命较短。

在一些实施例中，检测单元还可以包括：设置在锁孔的底部的第三检测器件；其中，当锁杆插入至锁孔中时，锁杆与第三检测器件接触，主控单元根据第三检测器件发送的检测信号判断锁杆处于插入状态。

以下参考附图对本公开进行具体描述。
本公开提供了一种智能锁，主要应用于物流监管领域，尤其是用于货厢(例如，集装箱)中的子母型安全锁中的子安全锁。参见图1和图2，根据本公开实施例，智能锁10包括：彼此能够进行锁开和锁闭配合的锁体100和锁杆200。锁体100具有锁孔101。锁杆200独立于锁体100存在。锁杆能够插入到锁体的锁孔中和从锁体的锁孔中拔出。图1显示了根据本公开实施例的智能锁处于锁杆未插入锁体中的状态，而图2显示了根据本公开实施例的智能锁处于锁杆插入锁体中并由限制装置约束时的状态。当锁杆200插入锁体100的锁孔101中时，两者之间形成锁闭配合状态。而当锁杆200被从锁体100的锁孔101中拔出时，两者之间形成锁开状态，此时，锁杆200可以完全脱离锁体100，独立于锁体100存在。根据本公开实施例，智能锁10还包括限制装置，限制装置设置在锁体100内部。限制装置主要用于限制锁杆200相对于锁孔101的拔出或插入，也即是限制锁杆200相对于锁孔101的拔插操作，从而确保智能锁能够稳定地处于锁闭配合状态，或者避免锁杆被无意识地插入锁体锁孔中。
根据本公开实施例，如图1和图2所示，限制装置包括：第一限制构件310和第二限制构件320。第一限制构件310可移动地设置在锁体100内部，并且能够移动闩锁至锁体100的锁孔101内以限制锁杆200相对于锁孔101的拔出或插入。而第二限制构件320同样可移动地设置在锁体100内部，并且能够抵接至第一限制构件310以限制第一限制构件310的移动。这样，当智能锁10需要获得锁闭状态时，将锁杆200插入锁体100的锁孔101内后，可以通过限制装置将锁杆200机械地约束在锁体100的锁孔101内，从而确保智能锁能够稳定地处于锁闭配合状态；而当智能锁10需要获得锁开状态时，限制装置解除对锁杆200的机械约束，使得锁杆200能够自由进出锁体100的锁孔101，以获得 锁开状态；进一步地，如有必要，当锁杆200离开锁体100的锁孔101时，可以再次将限制装置设定为机械约束状态，避免锁杆被无意识地插入锁体锁孔中。
在本公开的一个示例性实施例中，如图1和图2所示，锁杆200具有大致线性杆体形状，其一端(如图中的下端)具有锁合部。锁体100具有用于接收锁杆200的锁孔101。第一限制构件310可移动地设置在锁体内部并采用销体(限位销)形式，限位销的一端具有能够与锁杆200的锁合部进行锁合配合的对应的锁合部。第一限制构件(在本实施例中为限位销)310在锁体100内部能够沿大致垂直于锁孔100的延伸方向的方向移动，并且第一限制构件(在本实施例中为限位销)310的至少一部分(尤其是对应的锁合部)能够移动到锁体100的锁孔101内以闩锁至锁杆200的锁合部。第二限制构件320可移动地设置在锁体200内部并采用滑块形式。在图示的实施例中，第二限制构件(在本实施例中为滑块)320具有中心部分321延伸自中心部分321的抵接部分322。在本实施例中，在锁体100内部内，第二限制构件(在本实施例中为滑块)320能够在第一位置和第二位置之间移动；其中，在第一位置(如图2所示)处，第二限制构件(在本实施例中为滑块)320的抵接部分322抵接至第一限制构件(在本实施例中为限位销)310的与对应的锁合部相反的另一端，以约束第一限制构件的移动，而在第二位置(如图1所示)处，第二限制构件(在本实施例中为滑块)320脱离于第一限制构件(在本实施例中为限位销)310，解除对第一限制构件移动的约束。
这样，当智能锁10需要获得锁闭状态时，将锁杆200插入锁体100的锁孔101内后，第一限制构件310(的至少锁合部所在的一端)被移动到锁孔100内以闩锁至锁杆200，随后，第二限制构件320被移动至第一位置(如图2所示)处，使得其抵接部分322抵接至第一限制构件310的另一端，以约束第一限制构件310的移动，从而通过第一限制构件310和第二限制构件320之间的配合将将锁杆200机械地约束在锁体 100的锁孔101内，进而确保智能锁能够稳定地处于锁闭配合状态；而当智能锁10需要获得锁开状态时，第二限制构件320被从第一位置(如图2所示)移动至第二位置(如图1所示)处，第二限制构件320的抵接部分322解除对第一限制构件310移动的约束，此时第一限制构件310能够自由移动(即可以移动出锁孔102)，使得锁杆200能够自由进出锁体100的锁孔101，以获得锁开状态。进一步地，如有需要，当锁杆200离开锁体100的锁孔101后，可以将第二限制构件320再从第二位置(如图1所示)移动至第一位置(如图2所示)，再次将第一限制构件310(的至少锁合部所在的一端)约束到锁孔100内，以阻止锁杆200插入锁孔101中，从而避免锁杆200被无意识地插入锁体100的锁孔101中。
本公开实施例提供的智能锁中，限制装置还可以包括：用于驱动第二限制构件320在锁体100内部的移动的驱动单元330。例如，驱动单元330设置在锁体100内部，并且能够驱动第二限制构件320在位于锁体100内部的第一位置和第二位置之间的移动。正如前面所描述的，在第一位置处，第二限制构件320抵接至第一限制构件310以约束第一限制构件310的移动，而在第二位置处，第二限制构件320脱离于第一限制构件310以解除对第一限制构件310移动的约束。在本公开的一个示例性实施例中，如图1和图2所示，驱动单元可以包括：驱动电机331，和由驱动电机331驱动的螺纹杆332。其中，螺纹杆332与第二限制构件(如图示实施例中的滑块)320构成螺纹驱动。更详细地，螺纹杆332与第二限制构件320中的中心部分321配合，以构成螺纹驱动。此外，在进一步的实施例中，还可以在螺纹杆332和第二限制构件320中的中心部分321之间设置导向盘，以确保上述螺纹驱动能够有效地驱动第二限制构件320在第一位置和第二位置之间的移动。
当然，在本公开的其它实施例中，限制装置也可以采用上述示例性实施例所描述的部件和/或结构之外的任意部件和/或结构，只需要能够对锁杆200相对于锁孔101的插拔操作起到移动限制作用即可。举例而 言，第一限制构件310可以倾斜于(而不必沿大致垂直于锁孔100的延伸方向的方向)锁孔100的延伸方向移动，只需能够进入锁体100的锁孔101起到约束作用即可。又例如，第二限制构件320的移动也可以不通过驱动电机进行驱动，而采用其它机构进行驱动。
根据本公开实施例，如图1和图2所示，智能锁10还可以包括检测单元400。如图所示，检测单元400设在锁体100内，用于检测锁杆200相对于锁孔101的插入操作或拔出操作。进一步地，检测单元400可以通过通信手段将检测结果发送至外界，以实现外界对智能锁10的监管，提高智能锁10的安全可靠性。
下面结合图2至图4详细描述根据本公开实施例提供的智能锁10中的安全检测结构。如图2至图4所示，智能锁10包括检测单元400和主控单元500。检测单元400设在锁体100内，用于检测锁杆200相对于锁孔101的插入操作或拔出操作并且发送检测信号。主控单元500与检测单元400通信连接，用于根据检测单元400发送的检测信号判断智能锁10的锁闭状态。这里，图2仅简单地示意了检测单元400(以第三检测器件430为例，将在下文中详细描述)在锁体100内的一个检测位置，而图3则详细地示意了检测单元中的各个检测器件的具体检测位置以及这些检测器件与智能锁10中的其他部件之间的配合关系。此外，图4显示了检测单元400与主控单元500之间相互通信。
具体地，如图3所示，检测单元可以包括：设置在第二限制构件320的第一位置处的第一检测器件410和设置在第二限制构件320的第二位置处的第二检测器件420。在图3所示的结构中，第一检测器件410设置在锁体内的第二限制构件320可移动的空间的顶部处，而第二检测器件420设置在锁体内的第二限制构件320可移动的空间的底部处。
当第二限制构件320被移动至第一位置以与第一检测器件410接触时(如图3所示的情况下)，第一检测器件410检测到第二限制构件320并且发送检测信号至主控单元500(参见图4)，主控单元根据第一检测器件410发送的检测信号判断智能锁100处于施封状态，在施封 状态下，锁杆200不能插入锁孔101或者不能从锁孔101拔出；而当第二限制构件320被移动至第二位置以与第二检测器件420接触时，第二检测器件420检测到第二限制构件320并且发送检测信号至主控单元，主控单元根据第二检测器件420发送的检测信号判断智能锁处于解封状态，在解封状态下，锁杆200能够自由地插入锁孔101或者从锁孔101拔出。
而且，如图3所示，检测单元还可以包括：设置在锁孔101的底部的第三检测器件430。当锁杆200插入至锁孔101中时，锁杆200与第三检测器件430接触，第三检测器件4300检测到锁杆200的插入并且发送检测信号至主控单元，主控单元根据第三检测器件430发送的检测信号判断锁杆200处于插入状态。
进一步地，在智能锁10处于施封状态下时，当第一检测器件410和第三检测器件430中的任一个所发出的检测信号消失时，主控单元判断智能锁10处于异常状态(例如意外被打开或被破坏)下。此时，主控单元可以配合智能锁(或者甚至整个物流货厢)的其他安全检测装置，为智能锁(或者甚至整个物流货厢)提供安全检测警告。
根据本公开实施例，第二限制构件320可以由金属材质制成，而第一检测器件410、第二检测器件420和第三检测器件430可以采用弹簧顶针，例如pogo pin。可见，本公开实施例中，通过采用小体积、低成本的弹簧顶针(以pogo pin为例)作为安全检测辅助器件，相比于现有技术中采用的行程开关或霍尔器件等辅助器件，在确保了整个智能锁的安全性的前提下，增加了整个智能锁的可靠性和便利性，降低了制造成本。
根据本公开实施例，如图1和图2所示的智能锁10中，锁体100具有两个锁孔101，分别开设在锁体100的同一表面(在如图所示的实施例中为上表面)的相对的两端，其中，每个锁孔101适用于一个锁杆200的插拔操作。此外，如图3所示，每个锁孔101的底部设有一个第三检测器件430。
进一步地，在本公开的一些实施例中，智能锁10可以包括由多种锁杆件组成的锁杆组件，锁杆组件中的多个锁杆件可以具有不同长度和/或型号和/或外形。前述实施例中所描述的锁杆200选自锁杆组件中的其中一种长度和/或型号和/或外形的锁杆件。这样，本公开提供的智能锁10，可以根据不同需求提供不同的锁杆件，满足智能锁10的多样化要求。此外，在本公开的另一些实施例中，智能锁10也可以采用锁绳来取代前面所描述的锁杆，只要智能锁10中的限制装置的约束作用同样能够适用于锁绳的锁开或锁闭状态即可。
因此，本公开实施例提供的智能锁，通过采用机械构造的限制装置，提高了锁具的安全可靠性，降低制造成本。而且，本公开实施例提供的智能锁，锁杆完全独立于锁体存在，克服了传统锁具中锁绳和锁体之间的配合只能通过单方向插拔操作来实现的限制，增加了锁具的使用灵活度，方便锁具的操作。此外，本公开实施例提供的智能锁，可以从具有不同长度和/或型号和/或外形的锁杆件中选择满足不同需求的锁杆，能够适用于不同型号/尺寸货厢的锁闭要求。
但应该理解的是，上文所描述的内容为了突出本公开实施例的重点，而对部分细节进行了省略。本公开实施例也可以包括这些和/或那些技术细节。
虽然已参照几个实施例描述了本公开，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本公开能够以多种形式具体实施而不脱离公开的精神或实质，所以应当理解，上述实施例不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
