Rotation-direction sensing device and lock
The invention discloses a rotation-direction sensing device and a lock. A knob is arranged on a door inner panel of the lock. The knob is connected with a lock pin and the rotation-direction sensing device. Therefore, the lock can start an auxiliary motor to unlock or lock according to detecting and judging a rotation direction of the knob by the rotation-direction sensing device. The rotation-direction sensing device comprises a first panel and a second panel which are arranged in parallel. The first panel can rotate around the center of the first panel and is provided with magnetic steel. Atleast four Hall sensors are arranged on the second panel. The Hall sensors are circumferentially arranged on the second panel at equal intervals with the rotation center of the first panel as the circle center. When the magnetic steel on the first panel rotates to any position, at least one Hall sensor on the second panel can detect a magnetic field of the magnetic steel. Therefore, the lock canjudge the rotation direction according to the data change detected by each Hall sensor.
本发明公开了一种旋转方向传感装置和锁具。该锁具门内面板上设置有旋钮。旋钮连接锁销和旋转方向传感装置。由此锁具可以依据旋转方向传感装置对旋钮旋转方向的探测和判定，启动辅助电机以执行开锁或闭锁。该旋转方向传感装置包括平行设置的第一面板和第二面板。第一面板能够围绕其中心旋转，并设置有磁钢。第二面板上设有不少于四个的霍尔传感器。各个霍尔传感器以第一面板的旋转中心为圆心周向等间距地布置在第二面板上。第一面板上的磁钢旋转至任意位置时，第二面板上至少有一个霍尔传感器能够探测到磁钢的磁场。由此，锁具可以依据各个霍尔传感器所检测到的数据变化判定旋转方向。
