Embodiment 1

[0033] This embodiment is a rotation direction sensing device, which is used to connect the detected components, and detect and sense the rotation direction of the connected detected components. Such as Figure 4 As shown, the rotational direction sensing device includes a first panel 11 and a second panel 12 arranged parallel to each other. The first panel 11 is used to connect the detected component, and when the detected component rotates, it can drive the first panel 11 to rotate around its center. In this embodiment, the first panel 11 is a gear plate, which is connected to the detected component through the meshing between gears of the gear plate. The first panel 11 is provided with a magnetic steel 13 . The center distance between the magnetic steel 13 and the rotation center of the first panel 11 is R1. No less than four Hall sensors 14 are disposed on the second panel 12 . Such as Figure 4 In the given example, there are eight Hall sensors 14 arranged on the sec...

Embodiment 2

[0038] This embodiment is a lock, specifically, an intelligent door lock, which is used to be installed on a door panel. The lock, such as figure 1 As shown, a door inner panel 910 , a door outer panel 920 and a lock cylinder assembly 930 are included. The door inner panel 910 is a part for being disposed inside the door body. The door outer panel 920 is a part for being arranged on the outer side of the door body. The lock cylinder assembly 930 is a part arranged inside the door body. The lock cylinder assembly 930 is provided with a circuit board, a lock cylinder and a lock pin 931 . The circuit board is connected with the lock core; the lock core is connected with the lock pin 931 . But when the rotatable part of the lock core rotates, it can drive the lock pin 931 to stretch and realize opening and closing the door. The door outer panel 920 is provided with components for identity verification input, such as: a fingerprint input module, a password input module, a faci...

Abstract

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.

Description

technical field [0001] The invention relates to an intelligent door lock, in particular to an auxiliary unlocking mechanism of the intelligent door lock. Background technique [0002] At present, there are many automatic intelligent door locks on the market. This type of lock realizes automatic opening and closing of the door, which greatly facilitates the user. When the user goes out, the user only needs to press the unlock button to automatically open the door driven by the auxiliary motor. But there is a risk here: when the electronic part of the lock is damaged, the motor is damaged, the lock is underpowered, etc., the user cannot open the door by pressing the unlock button. At this time, the user needs to use the emergency knob to unlock, and the knob usually needs to be pressed to turn, which is inconvenient to operate. Under normal circumstances, the user will not use the knob, and it is difficult for the user to quickly unlock in an emergency. Contents of the inven...
