【具体实施方式】
为了便于理解本发明,下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施例。但是,本发明可以以许多不同的形式来实现,并不限于本文所描述的实施例。相反地,提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
请参阅图1至图3,一实施例中的智能门锁,包括第一锁体10和锁芯20,所述锁芯20能够在所述第一锁体10内运动,当锁芯20缩至第一锁体10内时表示完成开锁动作,当锁芯20完全延伸在锁体第一锁体10外时,表示完成闭锁动作。其中,所述第一锁体10包括主控器110、电机传动机构120、锁芯位置检测机构130,所述主控器110分别与电机传动机构120、锁芯位置检测机构130连接。智能门锁还包括基板140和电路板150,所述电机传动机构120安装在所述基板140上;所述基板140与所述电路板150对应设置且固定连接。
主控器110接收外部开锁信号并根据所述开锁信号输出开锁驱动信号给所述电机传动机构120;所述电机传动机构120根据所述开锁驱动信号并驱动所述锁芯20沿第一方向运动。锁芯20开始运动时,锁芯位置检测机构130在预设位置处检测所述锁芯20的位置信息,并将所述位置信息反馈给所述主控器110。当所述主控器110接收到所述位置信息时控制所述电机传动机构120按照预设步数旋转即可完成开锁动作。
所述电机传动机构120包括驱动电机121、蜗杆122、蜗轮123、动力齿轮124和旋转盘组件125。所述驱动电机121的输入端与所述主控器110电连接,所述驱动电机121的输出端、蜗杆122、蜗轮123、动力齿轮124依次机械连接。也即,当驱动电机121接收开锁驱动信号时,开始工作,驱动蜗杆122运动,并带动蜗轮123、动力齿轮124旋转。旋转盘组件125设置在动力齿轮124的中间位置,且与动力齿轮124同轴设置,动力齿轮124旋转能够带动所述旋转盘组件125旋转。同时,锁芯20嵌设在所述旋转盘1251中,旋转盘组件125旋转继而带动锁芯20运动。
所述电机传动机构120还包括光电编码器126,所述光电编码器126位于所述蜗轮123上。其中,光电编码器126包括光电开关1261和转速分度盘1263,所述转速分度盘1263与所述蜗轮123的同轴设置,所述光电开关1261设置在所述蜗轮123上与所述主控器110电连接。光电编码器126用于检测所述蜗轮123的运动参数,其中运动参数包括旋转速度以及旋转的圈数,可将检测的运动参数实时传输至主控器110进行处理。
参考图4,在所述旋转盘组件125包括旋转盘1251以及设置在所述旋转盘1251上的第一滑块单元1252、第二滑块单元1253、第一弹性件1254和第二弹性件1255。在旋转盘1251上开设有滑动槽,第一滑块单元1252与所述第二滑块单元1253容置在滑动槽中,能够相对滑动且对称设置。同时,在旋转盘1251上还开设有用于容置第一弹性件1254、第二弹性件1255的容置槽。第一弹性件1254、第二弹性件1255平行设置在所述第一滑块单元1252、第二滑块单元1253之间且沿所述第一滑块单元1252、第二滑块单元1253的相对滑动的方向设置。
其中,第一滑块单元1252包括第一圆柱1252a、第一滑块1252b,所述第二滑块单元1253包括第二圆柱1253a、第二滑块1253b。所述第一圆柱1252a和第二圆柱1253a对称设置在所述旋转盘组件125的边缘;所述第一圆柱1252a、第一滑块1252b抵接;所述第二圆柱1253a、第二滑块1253b抵接。所述第一弹性件1254的两端分别与所述第一滑块1252b、第二滑块1253b抵接;所述第二弹性件1255的两端分别与所述第一滑块1252b、第二滑块1253b抵接。
当第一圆柱1252a或第二圆柱1253a收到外力挤压时,会推动第一滑块1252b或第二滑块1253b相对运动时,就会使得第一弹性件1254、第二弹性件1255收缩。其中,第一弹性件1254和第二弹性件1255的推力大于锁芯20的扭力,进而驱动锁芯20运动。在一实施例中,第一弹性件1254和第二弹性件1255均为弹簧件,在其他实施例中,第一弹性件1254和第二弹性件1255还可以为其他可以具有收缩缓冲作用的弹性件。
动力齿轮124的内侧还对称设有第一凸包1241和第二凸包1242;所述第一凸包1241与所述第一圆柱1252a抵接,所述第二凸包1242与所述第二圆柱1253a抵接。动力齿轮124在旋转的过程中,第一凸包1241会推动第一圆柱1252a,第二凸包1242推动第一圆柱1252a,即可带动旋转盘组件125旋转。
在一实施例中,若第一锁体10安装在门右侧,锁芯20位于处于右侧闭锁状态时,其第一凸包1241位于所述第一圆柱1252a的顺时针方向;其第二凸包1242位于所述第二圆柱1253a的顺时针方向。当动力齿轮124逆时针旋转时,其第一凸包1241推动所述第一圆柱1252a;第二凸推动第二圆柱1253a,继而驱动第一弹性件1254、第二弹性件1255带动锁芯20逆时针旋转。
在一实施例中,若第一锁体10安装在门左侧,锁芯20位于处于左侧闭锁状态,时,其第一凸包1241位于所述第一圆柱1252a的逆时针方向;其第二凸包1242位于所述第二圆柱1253a的逆时针方向。当动力齿轮124顺时针旋转时,其第一凸包1241推动所述第一圆柱1252a;第二凸推动第二圆柱1253a,继而驱动第一弹性件1254、第二弹性件1255带动锁芯20顺时针旋转。
参考图5和图7,所述锁芯位置检测机构130包括第一磁铁131、第二磁铁132;所述第一磁铁131、第二磁铁132设置在所述旋转盘组件125上,所述第一磁铁131、第二磁铁132对称设置,且设置在所述第一圆柱1252a、第二圆柱1253a的对称轴上。
所述锁芯位置检测机构130还包括分别与所述主控器110连接的第一霍尔传感器133、第二霍尔传感器134、第三霍尔传感器135和第四霍尔传感器136。第一霍尔传感器133、第二霍尔传感器134、第三霍尔传感器135、第四霍尔传感器136以及所述主控器110均位于所述电路板150上,相对于旋转盘组件125静止不动。其第一圆柱1252a、第一磁铁131均位于旋转盘1251上,其旋转盘1251位于基板140上,可以在基板140上旋转。在一实施例中,基板140与电路板150对应设置,可使所述第一霍尔传感器133、第二霍尔传感器134分别对应位于所述第一磁铁131的两侧,所述第三霍尔传感器135、第四霍尔传感器136分别对应位于所述第二圆柱1253a的两侧。旋转盘1251在旋转的过程中,其第一磁铁131、第二磁铁132也会随之旋转,其第一霍尔传感器133、第二霍尔传感器134、第三霍尔传感器135和第四霍尔传感器136均为磁铁传感器,通过检测第一磁铁131、第二磁铁132的磁场强度,即可判断出旋转盘1251的转动信息,继而可以检测锁芯20的位置信息。
在一实施例中,第一锁体10安装在门右侧,参考图5,主控器110接收到开锁信号即刻输出开锁驱动信号至驱动电机121。驱动电机121启动,驱动蜗杆122运动,并带动蜗轮123旋转,进而带动动力齿轮124旋转逆时针旋转,其旋转盘组件125也会逆时针旋转。由于锁芯20嵌设在旋转盘组件125中,旋转盘组件125的逆时针旋转会使锁芯20缩至第一锁体10内。
旋转盘组件125在逆时针旋转的过程中,第一磁铁131越过第一霍尔传感器133时,第一霍尔传感器133输出低电平信号给所述主控器110;旋转盘组件125继续逆时针旋转,第二磁铁132B越过第四霍尔传感器136时,第四霍尔传感器136输出低电平信号给所述主控器110。当主控器110接收第四霍尔传感器136发出的低电平信号时,开始对光电编码器126接收到的信号变化次数进行计数,当光电编码器126的计步数达到预设步数时,即可完成开锁动作。在一实施例中,光电编码器126预设步数为4步。在其他实施例中,可以根据实际的需求,来设定具体的预设步数。
在完成开锁动作时,锁芯20位于第一锁体10内且锁芯20在第一锁体10内没有可移动的空间。其驱动电机121不会立刻停止下来,会继续驱动动力齿轮124逆时针旋转,此时,第一凸包1241会推动第一滑块单元1252,第二凸包1242会推动第二滑块单元1253,进而挤压第一弹性件1254、第二弹性件1255,可使第一凸包1241越过第一圆柱1252a,第二凸包1242越过第二圆柱1253a,为反向转动下次闭锁做好准备,参考图6。
主控器110还用于根据所述开锁动作的时刻延迟发出闭锁驱动信号至所述电机传动机构120;所述电机传动机构120根据所述闭锁驱动信号驱动所述锁芯20沿第二方向运动;所述锁芯位置检测机构130检测所述锁芯20的位置信息,并将所述位置信息反馈给所述主控器110;所述主控器110根据所述位置信息控制所述电机传动机构120按照预设步数旋转后停止完成闭锁动作,其中,第一运动方向与第二运动方向相反。
当完成开锁动作时,主控器110开始计时,当达到预设时长时,主控器110发出闭锁驱动信号并输出给驱动电机121。在一实施例中,预设时长为15秒,当然,其预设时长还可以根据实际需求来设定。驱动电机121接收闭锁驱动信号,驱动蜗杆122运动,并带动蜗轮123旋转,进而带动动力齿轮124旋转顺时针旋转,其旋转盘1251也会顺时针旋转。由于锁芯20嵌设在旋转盘1251中,旋转盘1251的顺时针旋转会使锁芯20延伸至第一锁体10外。相应的,旋转盘组件125在顺时针旋转的过程中,主控器110依次接收第四霍尔传感器136、第一霍尔传感器133输出低电平信号。当主控器110接收第一霍尔传感器133发出的低电平信号时,开始对光电编码器126接收到的信号变化次数进行计数,当光电编码器126的计步数达到预设步数时,即可完成闭锁动作。在一实施例中,光电编码器126预设步数为4步。在其他实施例中,可以根据实际的需求,来设定具体的预设步数。
在完成开锁动作时,锁芯20位于第一锁体10外的极限位置处,其驱动电机121不会立刻停止下来,会继续驱动动力齿轮124顺时针旋转,此时,第一凸包1241会推动第一滑块单元1252,第二凸包1242会推动第二滑块单元1253,进而挤压第一弹性件1254、第二弹性件1255,可使第一凸包1241越过第一圆柱1252a,第二凸包1242越过第二圆柱1253a,为反向转动下次开锁做好准备。也即,在开锁动作完成后,一定时间延迟后,会自动完成闭锁动作,提供了安全性,同时也节省了功耗。
在一实施例中,第一锁体10安装在门左侧,参考图7,主控器110接收到开锁信号即刻输出开锁驱动信号至驱动电机121。驱动电机121启动,驱动蜗杆122运动,并带动蜗轮123旋转,进而带动动力齿轮124旋转顺时针旋转,其旋转盘1251也会顺时针旋转。由于锁芯20嵌设在旋转盘组件125中,旋转盘组件125的顺时针旋转会使锁芯20缩至第一锁体10内。
旋转盘组件125在顺时针旋转的过程中,第一磁铁131越过第二霍尔传感器134时,第二霍尔传感器134输出低电平信号给所述主控器110;旋转盘组件125继续顺时针旋转,第二磁铁132B越过第三霍尔传感器135时,第三霍尔传感器135输出低电平信号给所述主控器110。当主控器110第三霍尔传感器135发出的低电平信号时,开始对光电编码器126接收到的信号变化次数进行计数,当光电编码器126的计步数达到预设步数时可完成开锁动作。在一实施例中,光电编码器126预设步数为4步,也即动力齿轮124大概转动20°左右。在其他实施例中,可以根据实际的需求,来设定具体的预设步数。
在完成开锁动作时,参考图8,锁芯20位于第一锁体10内且锁芯20在第一锁体10内没有可移动的空间。其驱动电机121不会立刻停止下来,会继续驱动动力齿轮124顺时针旋转,此时,第一凸包1241会推动第一滑块单元1252,第二凸包1242会推动第二滑块单元1253,进而挤压第一弹性件1254、第二弹性件1255,可使第一凸包1241越过第一圆柱1252a,第二凸包1242越过第二圆柱1253a,为反向转动下次闭锁做好准备。
当完成开锁动作时,主控器110开始计时,当达到预设时长时,主控器110发出闭锁驱动信号并输出给驱动电机121。在一实施例中,预设时长为15秒,当然,其预设时长还可以根据实际需求来设定。驱动电机121接收闭锁驱动信号,驱动蜗杆122运动,并带动蜗轮123旋转,进而带动动力齿轮124旋转逆时针旋转,其旋转盘1251也会逆时针旋转。由于锁芯20嵌设在旋转盘1251中,旋转盘1251的逆时针旋转会使锁芯20延伸至第一锁体10外。相应的,旋转盘组件125在逆时针旋转的过程中,主控器110依次接收第三霍尔传感器135、第二霍尔传感器134输出低电平信号。当主控器110接收第二霍尔传感器134发出的低电平信号时,开始对光电编码器126接收到的信号变化次数进行计数,当光电编码器126的计步数达到预设步数时,即可完成闭锁动作。在一实施例中,光电编码器126预设步数为4步。在其他实施例中,可以根据实际的需求,来设定。也即,在开锁动作完成后,一定时间延迟后,会自动完成闭锁动作,提供了安全性,同时也节省了功耗。
上述智能门锁的结构紧凑、整体尺寸小,在完成开锁、闭锁动作的过程中,通过蜗轮123、蜗杆122、动力齿轮124传动组合的二级传动实现了全自动对锁芯20的开启和闭合,不需要用户手动开锁。同时通过两个磁铁、四个霍尔传感器以及光电编码器126可以对锁芯20的位置进行精准的定位计步,比普通开关锁少了3/4的动作路径,实现可调式往返最短时间的开锁、闭锁动作,极大的节省了开锁、闭锁的时间和功耗。
此外,还提供一种智能门锁系统,参考图9和图10,智能门锁系统包括第二锁体30、无线移动终端40以及上述的智能门锁。所述第二锁体30与所述第一锁体10连接。所述第二锁体30上设有触摸模块310,与所述主控器110连接,用于检测外部触摸并输出触摸信号至所述主控器110。所述第一锁体10内还设有无线通讯模块140,与所述主控器110电连接,并与所述无线移动终端40进行无线通讯。所述主控器110根据所述触摸信号控制所述无线通讯模块140对所述无线移动终端40进行位置检测和身份认证;所述无线通讯模块140还用于输出开锁信号至所述主控器110。
