Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be described in detail below. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in the present application, all other implementation manners obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0025] Motor stalling is a situation in which the motor still outputs torque when the speed is zero. Due to the excessive load of the motor, the current when the motor is stalled (referred to as stalled current) can reach up to 7 times the rated current, which affects the service life of the motor. , Excessive current is transmitted to the main chip of the door lock, which will not only damage the chip but also burn out the motor after a long time. This applicati...

Abstract

The invention provides a door lock and a control method of the door lock, and belongs to the technical field of smart home. The control method comprises the steps that gear position data when the door lock executes target operation are detected through a position sensor arranged in the door lock, and the target operation comprises door lock opening operation and / or door lock closing operation; and according to the gear position data, a gear of the door lock is controlled to execute reset operation through a motor in the door lock. According to the control method, the probability of motor stalling can be prevented or reduced in advance.

Description

technical field [0001] This application belongs to the technical field of smart home, and specifically relates to a door lock and a control method for the door lock. Background technique [0002] With the increasing social material wealth and the improvement of people's living standards, safety has become one of the most concerned issues of residents. Self-safety is very important, so the listing of smart door locks meets the requirements of safety, reliability, anti-theft and ease of use. [0003] The smart door lock motor is an indispensable and important component for the smart door lock to work normally. The smart door lock motor plays the role of the heart in the smart lock. The service life and response speed of the motor have a great impact on the user experience. The most serious thing for the motor is the stalling phenomenon. The motor stalling means that when the motor is energized and running normally, it is affected by external factors and suddenly the speed is ...
