具体实施方式
下面将结合本申请实施方式中的附图，对本申请实施方式中的技术方案进行清楚、完整地描述。其中，附图仅用于示例性说明，表示的仅是示意图，不能理解为对本申请的限制。显然，所描述的实施方式仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施方式，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施方式，都属于本申请保护的范围。
除非另有定义，本申请所使用的所有的技术和科学术语与本领域技术人员通常理解的含义相同。本申请在说明书中所使用的术语只是为了描述具体实施方式的目的，不是旨在限制本申请。在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”等的后缀仅为了有利于本申请的说明，其本身没有特定的意义。因此，“模块”、“部件”或“单元”等可以混合地使用。
本申请提供一种智能连接装置，所述智能连接装置利用负载检测模块来检测负载连接端与负载设备的连接状态，并利用所述负载检测模块输出的检测信号来自动切换控制器的工作状态，从而可在负载设备反接时防止控制器响应用户触发生成的电源强制输出信号而输出导通信号来导通开关模块，如此，可在负载设备连接异常的情况下确保所述开关模块处于断开状态，以防止电源模块对所述负载设备进行放电。
请参阅图1，图1为本申请第一实施方式提供的一种智能连接装置100的功能模块示意图。如图1所示，所述智能连接装置100包括电源连接端20、负载连接端30以及开关模块40，其中，所述电源连接端20用于与电源模块600连接，所述负载连接端30用于与负载设备700连接。所述开关模块40连接于所述电源连接端20与所述负载连接端30之间，所述开关模块40用于导通或断开所述电源连接端20和所述负载连接端30之间的连接，从而实现所述电源模块600对所述负载设备700的放电输出的控制。
需要说明的是，本申请中的“连接”包括元器件之间实现传输电能的实体线路连接形式和/或无线连接形式。本申请中的“连接”可以包括直接连接或间接连接。以本申请实施例中的电源连接端连接开关模块为例，电源连接端可以直接连接开关模块，电源连接端也可以通过其它电路模块(例如二极管、保护电路、检测电路等)间接连接开关模块，不影响开关模块实现电源连接端和负载连接端之间的传输控制，上述实施方式均在本申请实施例的保护范围内。
在本实施方式中，所述电源连接端20、所述负载连接端30以及所述开关模块40构成所述电源模块600对所述负载设备700输出放电的放电输出回路11，所述开关模块40用于导通或断开所述放电输出回路11。如此，所述电源模块600能够通过所述智能连接装置100对所述负载设备700放电。
在本实施方式中，如图2所示，所述电源连接端20包括电源正连接端BAT+和电源负连接端BAT-，其中，所述电源正连接端BAT+和所述电源负连接端BAT-用于与所述电源模块600的正极和负极一一对应连接，所述电源负连接端BAT-还与接地端GND连接。所述电源模块600通过所述电源连接端20接入所述智能连接装置100中，从而为所述智能连接装置100提供工作电压，以及通过所述开关模块40为所述负载设备700提供电能。可以理解的是，当所述智能连接装置100应用于应急启动电源设备中时，所述电源模块600可为所述应急启动电源设备的内置储能组件。当所述智能连接装置100应用于电瓶夹设备中时，所述电源模块600可为外部电源设备，例如外部应急启动电源或其他储能电源设备的储能组件。
所述负载连接端30包括负载正连接端CAR+和负载负连接端CAR-，其中，所述负载正连接端CAR+和所述负载负连接端CAR-用于与所述负载设备700的正极和负极一一对应连接，所述负载负连接端CAR-还与接地端PGND连接，其中，所述接地端GND和所述接地端PGND为不同的电源网络的参考地。在本实施方式中，所述负载设备700可为汽车电池或汽车引擎，所述汽车电池包括但不限于铅酸电池、锂电池、超级电容等。例如，假设所述电源模块600为外部应急启动电源包含的储能组件，所述负载设备700为汽车电池或汽车引擎，则当外部应急启动电源通过所述电源连接端20正确接入所述智能连接装置100中，且所述汽车电池正确接入所述负载连接端30中时，所述外部应急启动电源即可通过所述电源连接端20、所述开关模块40、所 述负载连接端30构成的所述放电输出回路11启动放电输出，从而为所述汽车电池或汽车引擎提供应急启动电源，这里也可以理解为所述外部应急启动电源给所述汽车引擎提供打火电流，如此，汽车在所述汽车电池电量不足时也能被启动。
请再次参阅图1，所述智能连接装置100还包括控制器50，所述控制器50用于输出导通信号RELAY_EN2。在本实施方式中，所述开关模块40基于所述控制器50输出的导通信号RELAY_EN2来导通所述电源连接端20与所述负载连接端30之间的连接，以实现所述电源模块600对所述负载设备700的放电输出。
具体地，请再次参阅图2，在本实施方式中，所述开关模块40包括开关装置41以及开关驱动模块42，其中，所述开关装置41连接于所述电源连接端20和所述负载连接端30之间。在本实施方式中，所述开关装置41连接于所述电源正连接端BAT+和所述负载正连接端CAR+之间。可以理解的是，在其他实施方式中，所述开关装置41也可以连接于所述电源负连接端BAT-和所述负载负连接端CAR-之间。
所述开关装置41可采用电磁式继电器或者半导体功率器件，例如MOSFET。在本实施方式中，如图2所示，所述开关装置41采用电磁式继电器K1，所述开关装置41通过其驱动电源回路410来接收电能，并基于所述电能导通所述电源模块600与所述负载设备700之间的连接。应说明的是，在本实施方式中，所述开关装置41在未接收到电能时自动断开所述电源模块600与所述负载设备700之间的连接。
具体地，所述继电器K1可包括铁芯a、绕设于铁芯a的线圈b、摆臂c以及两个触点d和e。所述继电器K1的其中一个触点d连接于所述电源正连接端BAT+，另一个触点e连接于所述负载正连接端CAR+，所述线圈b串联于所述开关装置41的驱动电源回路410中。这里也可以理解为，所述继电器K1的线圈b构成所述驱动电源回路410的一部分。在本实施方式中，所述线圈b的第一端与所述驱动电源回路410的接地端连接，所述线圈b的第二端与所述驱动电源回路410的电源端连接，并且，所述线圈b的第一端还通过二极管D2与所述线圈b的第二端连接，其中，所述二极管D2的正极与所述线圈b的第一端连接，负极与所述线圈b的第二端连接。
使用时，在给所述线圈b通电后，即所述开关装置41接收到电能，线圈b中就会有电流流过，从而产生电磁效应，摆臂c就会在电磁力吸引的作用下被吸向铁芯a，两个触点d和e通过摆臂c连接，即，所述开关装置41处于导通状态，从而实现所述电源正连接端BAT+和所述负载正连接端CAR+之间的连接。当线圈b断电后，即所述开关装置41未接收到电能，线圈b中的电磁效应消失，铁芯a上的电磁吸力也随之消失，摆臂c返回原来的位置，从而断开两个触点d和e的连接，即，所述开关装置41处于断开状态，进而断开所述电源正连接端BAT+和所述负载正连接端CAR+之间的连接。
在本实施方式中，所述智能连接装置100还包括连接于所述开关装置41的驱动电源回路410中的驱动电源模块43。其中，所述驱动电源模块43用于通过所述驱动电源回路410给所述开关装置41提供电能。相应地，所述开关装置41在所述驱动电源回路410导通时能够接收到所述电能，并基于所述电能导通所述电源连接端20和所述负载连接端30之间的连接，从而使所述电源模块600能够对所述负载设备700进行放电输出。这里也可以理解为，所述驱动电源模块43构成所述驱动电源回路410的一部分，例如，所述驱动电源模块43可视为所述驱动电源回路410的电源端。
在一种实施方式中，所述驱动电源模块43与所述电源正连接端BAT+连接，以通过所述电源正连接端BAT+从所述电源模块600中获取所述电能，并通过所述驱动电源回路410将所述电能提供给所述开关装置41。可选地，在其他实施方式中，所述驱动电源模块43可与一稳压电源模块821(如图10所示)连接，以从所述稳压电源模块821中获取所述电能。
在本实施方式中，所述开关驱动模块42基于所述控制器50输出的导通信号RELAY_EN2来导通所述驱动电源回路410，从而使所述开关装置41能够接收到所述驱动电源模块43提供的电能。这里也可以理解为，所述开关驱动模块42构成所述驱动电源回路410的一部分，例如，所述开关驱动模块42可视为所述驱动电源回路410的开关电路。也就是说，在本实施 方式中，所述电源模块600给所述负载设备700放电的条件为：所述开关装置41的驱动电源回路410导通，且所述驱动电源模块43通过导通的所述驱动电源回路410给所述开关装置41提供电能。
在本实施方式中，所述开关驱动模块42的电路结构可采用图2所示的电路结构。下面将结合图2对所述开关驱动模块42的电路结构以及工作原理进行介绍。
所述开关驱动模块42包括驱动信号输入端421以及控制开关Q2，其中，所述驱动信号输入端421与所述控制器50连接，所述驱动信号输入端421用于接收所述控制器50输出的所述导通信号RELAY_EN2。所述控制开关Q2串联于所述驱动电源回路410中，所述控制开关Q2基于所述驱动信号输入端421接收到的所述导通信号RELAY_EN2导通所述驱动电源回路410。
在本实施方式中，所述控制开关Q2采用晶体管，所述控制开关Q2的第一连接端2与接地端GND连接，所述控制开关Q2的第二连接端3通过电阻R2与所述继电器K1的线圈b的第一端连接，如此，所述控制开关Q2通过其第一连接端2和第二连接端3串联于所述驱动电源回路410中。所述控制开关Q2的控制端1通过电阻R17与所述驱动信号输入端421连接。所述控制开关Q2的控制端1还通过电阻R3连接至接地端GND，以及通过二极管D6连接至所述驱动信号输入端421，其中，所述二极管D6的正极与所述控制开关Q2的控制端1连接，负极与所述驱动信号输入端421连接。
在本实施方式中，所述控制开关Q2采用高电平导通的晶体管，例如NMOS管或NPN三极管，所述导通信号RELAY_EN2为高电平信号。具体地，如图2所示，所述控制开关Q2采用NMOS管。所述控制开关Q2的控制端1、第一连接端2、第二连接端3与MOS管的栅极、漏极、源极一一对应。
工作时，若所述控制器50输出所述导通信号RELAY_EN2，则所述控制开关Q2的控制端1通过所述驱动信号输入端421接收到所述导通信号RELAY_EN2，使所述控制开关Q2导通，从而导通所述驱动电源回路410。可以理解的是，在所述控制器50未输出所述导通信号RELAY_EN2时，所述控制开关Q2由于其控制端1未接收到所述导通信号RELAY_EN2而处于断开状态，从而断开所述驱动电源回路410。
请再次参阅图1，在本实施方式中，所述智能连接装置100还包括强制输出触发模块70，所述强制输出触发模块70用于接收并响应用户的强制输出操作而触发所述控制器50输出所述导通信号RELAY_EN2。
具体地，请一并参阅图1和图2，所述强制输出触发模块70用于接收并响应用户的强制输出操作而生成电源强制输出信号。所述控制器50分别与所述开关驱动模块42的驱动信号输入端421以及所述强制输出触发模块70连接，所述控制器50用于接收并响应所述电源强制输出信号而输出所述导通信号RELAY_EN2，并将所述导通信号RELAY_EN2发送至所述开关驱动模块42的驱动信号输入端421。
在本实施方式中，所述强制输出触发模块70的电路结构可采用图3所示的电路结构。下面将结合图3对所述强制输出触发模块70以及所述控制器50的电路结构以及工作原理进行介绍。
请参阅图3，在本实施方式中，所述控制器50可采用可编程控制器件，比如微控制器(Micro-controller Unit，MCU)、可编程逻辑阵列(Field-Programmable Gate Array，FPGA)、或数字信号处理器(Digital Signal Processor，DSP)等。所述控制器50作为所述智能连接装置100的逻辑运算和控制中心，主要负责数据采集和转换、逻辑运算、数据通信及执行驱动输出等功能。在本实施方式中，所述控制器50采用微控制器U2，包括多个输入输出端口，所述控制器50可通过所述多个输入输出端口与其他功能模块或外部设备进行通信以及信息交互，从而可实现所述智能连接装置100的连接、驱动和控制等功能。
在本实施方式中，所述微控制器U2通过其电源引脚VDD&AVDD来接收供电，例如接收所述稳压电源模块821提供的稳定电压VCC(例如5V的直流电压)，所述微控制器U2还通过其接地引脚VSS&AVSS接地。可以理解的是，所述微控制器U2在正常工作时，既需要接收到供电，还需要 接地形成电流回路。若所述微控制器U2的电源引脚VDD&AVDD没有正常接收到供电，或者，所述微控制器U2的接地引脚VSS&AVSS没有接地形成电流回路，所述微控制器U2不能正常工作。
在本实施方式中，所述强制输出触发模块70包括按键S1，所述按键S1与所述微控制器U2连接，所述按键S1用于接收用户的按压操作而产生所述电源强制输出信号。
其中，所述按键S1可采用机械物理按键或触摸形式的虚拟按键构成。所述按键S1允许用户通过物理或者虚拟触摸按键与所述智能连接装置100的系统进行人机交互。在本实施方式中，所述按键S1采用机械物理按键，且连接于接地端与所述控制器50的检测引脚PA2/ICPCK之间。当用户按压所述按键S1时，所述按键S1将所述控制器50的检测引脚PA2/ICPCK连接到地，即给所述控制器50输入低电平信号，所述低电平信号即为所述电源强制输出信号。如此，用户可以通过按压所述按键S1来强制所述控制器50输出所述导通信号RELAY_EN2，从而控制所述电源模块600对所述负载设备700进行放电输出。可以理解的是，在本实施方式中，所述按键S1在常规状态下保持在断开状态。
使用时，若所述控制器50正常工作，则用户可以通过按压所述按键S1来强制所述控制器50输出所述导通信号RELAY_EN2，根据上文的介绍，所述开关驱动模块42的控制开关Q2的控制端1通过所述驱动信号输入端421接收到所述导通信号RELAY_EN2，使所述控制开关Q2导通，从而导通所述驱动电源回路410。可以理解的是，若用户未按压所述按键S1，则所述控制器50不会输出所述导通信号RELAY_EN2，所述控制开关Q2由于其控制端1未接收到所述导通信号RELAY_EN2而处于断开状态，从而断开所述驱动电源回路410。
请再次参阅图1，在本实施方式中，所述智能连接装置100还包括与所述负载连接端30连接的负载检测模块60，所述负载检测模块60用于检测所述负载连接端30与所述负载设备700的连接状态，并根据检测到的连接状态输出相应的检测信号C_EN。其中，所述检测信号C_EN用于切换所述控制器50的工作状态。
在本实施方式中，所述控制器50的工作状态至少包括第一状态和第二状态，所述控制器50在处于所述第一状态时能够输出所述导通信号RELAY_EN2来导通所述开关模块40，从而导通所述电源连接端20和所述负载连接端30之间的连接，使所述电源模块600能够对所述负载设备700放电。
所述控制器50在处于所述第二状态时暂停工作，无法输出所述导通信号RELAY_EN2。相应地，所述开关模块40在所述控制器50暂停工作时未接收到所述导通信号RELAY_EN2，因此，所述开关模块40处于断开状态，从而断开所述电源连接端20和所述负载连接端30之间的连接，使所述电源模块600无法对所述负载设备700放电。
具体地，在本实施方式中，所述控制器50在处于所述第一状态时能够响应所述电源强制输出信号而输出所述导通信号RELAY_EN2。所述控制器50在处于所述第二状态时由于暂停工作，无法响应所述电源强制输出信号，因此无法输出所述导通信号RELAY_EN2。
在本实施方式中，所述检测信号C_EN包括第一检测信号和第二检测信号，所述负载检测模块60用于在检测到所述负载连接端30空载或所述负载设备700正接到所述负载连接端30时输出所述第一检测信号，其中，所述第一检测信号用于将所述控制器50的工作状态切换为所述第一状态。
所述负载检测模块60还用于在检测到所述负载设备700反接到所述负载连接端30时输出所述第二检测信号，其中，所述第二检测信号用于将所述控制器50的工作状态切换为所述第二状态。
由于用户可以通过所述强制输出触发模块70来强制所述控制器50输出所述导通信号RELAY_EN2，在不满足启动条件时，若用户强制所述控制器50输出所述导通信号RELAY_EN2来导通所述开关装置41，以控制所述电源模块600对所述负载设备700放电，可能会导致安全事故的发生。在本实施方式中，在检测到所述负载设备700反接至所述负载连接端30时，通过所述负载检测模块60输出的第二检测信号来将所述控制器50的工作状态切换为所述第二状态，使所述控制器50无法响应用户操作所述强制输出触发模块70而产生的电源强制输出信号，因 此，所述控制器50无法输出所述导通信号RELAY_EN2，这时，即使用户操作所述强制输出触发模块70，所述开关装置41也不会被导通，从而能够有效地防止所述电源模块600对所述负载设备700进行放电输出，如此，可以确保电路的用电安全。
图4为本申请的第二实施方式提供的一种智能连接装置101的功能模块示意图。应说明的是，所述智能连接装置101与图1所示的智能连接装置100对应。
如图4所示，在所述第二实施方式中，所述智能连接装置101还包括与所述控制器50连接的使能控制模块81，所述智能连接装置101包括的负载检测模块60将所述检测信号C_EN发送至所述使能控制模块81，以通过所述使能控制模块81来切换所述控制器50的工作状态，从而控制所述导通信号RELAY_EN2的输出，进而控制所述开关模块40的通断，以控制所述电源模块600对所述负载设备700的放电输出。
在所述第二实施方式中，所述第一状态包括使能状态，所述第二状态包括禁能状态，所述控制器50在处于所述使能状态时能够正常工作，所述控制器50在处于所述禁能状态时暂停工作。
具体地，所述使能控制模块81用于根据所述第一检测信号来将所述控制器50的工作状态切换至使能状态，以及根据所述第二检测信号来将所述控制器50的工作状态切换至禁能状态。
