Embodiment 1

[0031] This embodiment has made a detailed introduction to the angular position detection device of the electric lock reducer box, refer to figure 2 , image 3 As shown, a Hall switch assembly 10 is arranged on the rotating shaft 5 of the gear reducer box 4 of the lock. In the Hall switch assembly 10, several Hall switches are evenly distributed around the rotating shaft 5. The rotating shaft 5 is provided with a permanent magnet 11 to sense the Hall switch. , comparing the output currents of the Hall switches to determine which Hall switch the permanent magnet 11 is close to, thereby detecting the rotation angle of the rotating shaft 5 .

[0032] The Hall switch assembly 10 includes a ring-shaped PCB 10-9, and several Hall switches are evenly distributed on the ring-shaped PCB 10-9. Wires 12 are connected to the PCB 10-9.

[0033] The annular PCB10-9 is fixed on the vertical plate inside the reduction box, and the rotating shaft 5 passes through the central hole of the ann...

Embodiment 2

[0042] This embodiment has done a detailed introduction to the electric lock, refer to figure 2 , image 3 As shown, a lock body (not shown in the figure), a lock cylinder (refer to figure 1 Lock core 9) in, motor 8 and reduction box 4, reduction box 4 is provided with rotating shaft 5 and is connected with lock core, is also provided with electric lock reduction box rotating shaft angular position detection device described in embodiment 1.

[0043] There is a dial 2 on the lock cylinder, refer to figure 1 As shown, the rotating shaft 5 drives the dial 2 to rotate so as to open the lock body or close the lock body.

[0044] The working principle of the lock cylinder used in this embodiment can refer to the door locks in the prior art, such as traditional door locks or electronic locks.

[0045] The rotating shaft 5 is provided with a rectangular hole in the axial direction, and the lock cylinder is provided with a transmission shaft with a rectangular cross section connec...

Abstract

The invention discloses a detection device for an angular position of a rotating shaft of a speed reducer of an electric lock. The rotating shaft of the speed reducer of the electric lock is provided with a Hall switch assembly in a matching manner, a plurality of Hall switches are uniformly distributed around the rotating shaft in the Hall switch assembly, a permanent magnet and a Hall switch sensor are arranged on the rotating shaft, and which Hall switch is closer to the permanent magnet is judged by comparing output currents of the Hall switches, so as to detect a rotation angle of the rotating shaft. According to the detection device disclosed by the invention, the angle of the rotating shaft is detected by the Hall switch assembly, thereby avoiding idling of the rotating shaft, improving the accuracy and the sensitivity of manipulation of the electric lock, shortening the unlocking time and reducing the power consumption.

Description

technical field [0001] The invention relates to a device for detecting the angular position of a rotating shaft of a reduction box of an electric lock, and also relates to an electric lock. Background technique [0002] Electric locksets in the prior art, for example figure 1 Shown, comprise parts such as lock cylinder 9, motor 8, power transmission shaft 3, reduction box 4, rotating shaft 5 (belonging to the sub-piece on the reduction box 4), light blocking plate 6, photoelectric sensor 7. Wherein the light-blocking sheet 6 is fixed on the rotating shaft 5, and as the rotating shaft 5 rotates, when the light-blocking sheet 6 passes through the photoelectric sensor 7, the induction of the photoelectric sensor 7 is caused to detect the rotation angle of the rotating shaft. [0003] The position detection mechanism of the reduction box used on the existing electric locks cannot determine the angular position of the rotating shaft relatively accurately, but can only ensure tha...
