Example Embodiment

[0030] Example 1

[0031] This embodiment gives a detailed introduction to the angular position detection device of the rotating shaft of the electric lock gearbox, refer to figure 2 , image 3 As shown, the shaft 5 of the lock gear reduction box 4 is provided with a Hall switch assembly 10. In the Hall switch assembly 10, a number of Hall switches are evenly distributed around the shaft 5, and the shaft 5 is provided with a permanent magnet 11 and a Hall switch sensor. , Compare the output current of the Hall switch to determine which Hall switch the permanent magnet 11 is close to, so as to detect the rotation angle of the rotating shaft 5.

[0032] The Hall switch assembly 10 includes a ring-shaped PCB 10-9, and a number of Hall switches are uniformly distributed on the ring-shaped PCB 10-9. Wire 12 is connected to PCB10-9.

[0033] The ring-shaped PCB10-9 is fixed on the vertical plate inside the gearbox, and the rotating shaft 5 passes through the center hole of the ring-shap...

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...
