Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1
The embodiment is a rotation direction sensing device, which is used for connecting a detected component and detecting and sensing the rotation direction of the connected detected component. As shown in fig. 4, the rotation direction sensing device includes a first panel 11 and a second panel 12 arranged in parallel with each other. The first panel 11 is used for connecting a detected component, and when the detected component rotates, the first panel 11 can be driven to rotate around the center of the detected component. In this embodiment, the first panel 11 is a gear plate, and the detected member is connected by meshing between gears of the gear plate. The first panel 11 is provided with magnetic steel 13. The center distance of the magnetic steel 13 from the rotation center of the first panel 11 is R1. At least four hall sensors 14 are arranged on the second panel 12. In the example shown in fig. 4, eight hall sensors 14 are provided on the second panel 12. The hall sensors 14 are arranged on the second panel 12 at equal intervals in the circumferential direction around the center of rotation of the first panel 11, and the radius R2 at which the hall sensors 14 are arranged is the same as R1. That is, the hall sensors 14 of the second panel 12 enclose a circle having a center at the axial center of the rotation axis of the first panel 11, and the radius R2 of the circle is the same as the center distance R1 of the magnetic steel 13 from the rotation center of the first panel 11.
When the first panel 11 is rotated by the detected component, the magnetic steel 13 on the first panel 11 rotates around the rotation axis of the first panel 11. When the magnetic steel 13 rotates around the rotation axis of the first panel 11, the magnetic steel 13 moves along the hall sensor 14 arrangement direction. When the magnetic steel 13 on the first panel 11 rotates to any position, the magnetic steel can be detected by at least one hall sensor 14 on the second panel 12. Therefore, when the magnetic steel 13 rotates to any position, the hall sensor 14 at the corresponding position can detect the magnetic field generated by the magnetic steel 13. In the example shown in fig. 1, the magnetic steel 13 on the first panel 11 is a point-shaped magnetic steel with strong magnetism. For the magnetic steel with weak magnetism, in order to enable the magnetic steel 13 to be detected by the hall sensor 14 at the corresponding position when rotating to any position, the magnetic steel 13 with the arc-shaped structure as shown in fig. 5 can also be adopted. The arc-shaped magnetic steel 13 takes the rotation center of the first panel 11 as the center of circle, and the arc central angle is a 2. Generally, the arc central angle a2 of the arc magnetic steel should not be larger than the phase angle a1 between two adjacent hall sensors 14. In the example shown in fig. 5, the arc central angle a2 of the arc magnetic steel is the same as the phase angle a1 between two adjacent hall sensors 14.
It should be noted that there may be several magnetic steels 13 on the first panel 11, refer to fig. 6. In the example of fig. 6, there are two magnetic steels 13 on the first panel 11. The two magnetic steels have a phase angle of 180 degrees, or the two magnetic steels 13 are circumferentially arranged on the first panel 11 at equal intervals by taking the rotation center of the first panel 11 as a center. Specifically, in the case where a plurality of magnetic steels 13 are provided on the first panel 11, the respective magnetic steels 13 are circumferentially arranged on the first panel 11 at equal intervals around the rotation center of the first panel 11. In addition, this situation also generally requires that the number of the magnetic steels 13 is not more than one fourth of the number of the hall sensors 14 on the second panel 12.
In addition, for the magnetic steel 13 with the arc-shaped structure in the example of fig. 5, those skilled in the art understand that the arc-shaped magnetic steel 13 may be formed by piecing together a plurality of small magnetic steels.

The controller 400 is implemented by a circuit board within the plug assembly 930, including components such as a microprocessor, memory, and the like. The controller 400 implements the intelligence of the lockset by executing a program instruction set through a microprocessor. Specifically, in the lock of the present embodiment, the controller 400 determines the rotation direction of the knob 940 by receiving real-time data of each hall sensor 14, and then starts the auxiliary motor 500 according to the rotation direction of the knob 940 to perform auxiliary door opening. More specifically, the controller 400 determines the rotation direction of the knob 940 according to the front-back variation of the collected magnetic data of the hall sensor 14; if the rotation direction of the knob 940 is the door opening direction, the auxiliary motor 500 is started to perform auxiliary door opening, and at this time, the auxiliary motor 500 drives the transmission rod 950 to rotate, so as to drive the lock pin 931 to contract to realize the door opening action; if the rotation direction of the knob 940 is the door closing direction, the auxiliary motor 500 is started to perform the auxiliary door closing, and at this time, the auxiliary motor 500 drives the transmission rod 950 to rotate, so as to drive the lock pin 931 to extend out to achieve the door closing action.
In this embodiment, the knob 940 is connected to the transmission rod 950 through a pawl structure, so that the knob 940 can rotate to drive the transmission rod 950 to rotate; and when the transmission rod 950 rotates, the knob 940 cannot be driven to rotate. When the lockset works normally, after the knob 940 is rotated, the controller 400 judges the rotating direction of the knob 940 by receiving real-time data of each hall sensor 14, and then the auxiliary motor 500 is started according to the rotating direction of the knob 940, and the auxiliary motor 500 drives the transmission rod 950 to further rotate, so that the door opening or closing action is realized. When the lock is in an abnormal state, the door can be opened or closed by continuously rotating the knob 940 through the transmission of the transmission rod 950.
