Description

Technical Field

[0001] The present invention belongs to the technical field of clutches for intelligent door locks, and particularly relates to a multifunctional intelligent clutch switch. Background Art

[0002] An intelligent lock is an actuating component for locking doors in an access control system. With the advent of the intelligent era, smart home products, especially intelligent door locks, are increasingly used in people's lives and in a wider range of fields. While ensuring people's property and personal safety, intelligent locks also meet the requirements for humanization and intelligence. Different from traditional mechanical locks, intelligent locks are more intelligent in user identification, security, and management. The manifestation of the intelligence of an intelligent lock is whether it can be remotely controlled by a mobile phone and linked with smart home devices. Currently, various intelligent locks are emerging in an endless stream, each with its own characteristics. Regardless of the structure, intelligent locks rely on motors to drive clutch operations, which is the intelligent lock clutch. When a user unlocks or locks a lock through an IC card, password, fingerprint, facial recognition, etc., the clutch of the intelligent lock is required. For an intelligent lock, an intelligent lock clutch with good performance, few faults, long service life, and low cost is the direction for the existing technology to create, research, and develop.

[0003] In addition to electric control, some existing intelligent clutches are also equipped with manual clutch mechanisms to cope with the situation of electric mechanism failure. However, the manual clutch mechanism usually has poor anti-theft measures and there is a risk of being cracked. Therefore, when the manual clutch mechanism is not commonly used, it is necessary to design anti-theft measures for the manual clutch mechanism. Summary of the Invention
