Intelligent door lock controlled by clutch-type motor drive without lodging

Abstract

The invention relates to an intelligent door lock driving controlled by a clutch type motor, mainly comprising a front panel, a handle and a linear motion telescopic actuator, the handle is axially connected with a handle spline, the output shaft of the linear motion telescopic motor is connected with one end of a clutch driving control block, the other end of the clutch driving control block is axially connected with the front panel through the shaft hole of the clutch control block, the clutch driving control block is provided with a clutch control track; a mechanical lock core is mounted in the handle and fixedly connected with a lock core shifting fork including a connecting piece and a shifting fork head, a square rod key fastener includes a hole for inserting a square rod, a clutch fastener top block and a locating corner, a clutch fastener includes a clutch fastener main shaft hole, a clutch control shaft, a clutch top head and a key top head, the clutch fastener main shaft hole is axially connected with the handle spline through a clutch fastener shaft pin, the clutch control shaft is mounted on and slidably connected with the clutch control track. The invention has fast startup speed, flexible performance and reliable safety, and easy-block and easy-jamming phenomena occurred on a high-grade intelligent lock hardly occur.

Description

technical field [0001] The invention relates to the field of locks, and mainly relates to an intelligent door lock driven and controlled by a clutch-free motor. Background technique [0002] The current high-end electronic lock clutch mechanism is easy to jam mainly for the following reasons: [0003] 1. Motor transmission structure: The unlocking control mechanism is mainly completed by the motor plus the screw rod to drive the elastic spring back and forth. Defect is: the high screw rod of motor rotating speed is easy to wear and tear, and elastic spring is clamped in the middle section and can wear more when meeting bolt hole deviation, causes sometimes also can't open lock and short service life. [0004] 2. Mechanical clutch mechanism: most of the clutch mechanism is completed by push-pull shaft pin and insert block. Defect is: when unlocking, due to the use of motor transmission, the complete insertion of the latch can not be completed instantly in time, generally mo...

AI Technical Summary

Problems solved by technology

The defect is: the screw rod is easy to wear when the motor rotates at a high speed, and the elastic spring stuck in the middle will wear even more when the pin hole is deviated, resulting in sometimes the lock cannot be opened and the service life is short

Defect is: when unlocking, due to the use of motor transmission, the complete insertion of the latch can not be completed instantly in time, generally more than half a second, and pressing the handle when encountering impatience will cause the shaft pin and the plug of the clutch mechanism to deform and roll. Injury, internal and external clutch sleeve pulling, eccentricity, etc., so that it becomes a bad lock

[0005] 3. Locking and stuck fault: The plug-type clutch mechanism can only be fully inserted at the punctual point where the inner and outer shafts are synchronized, and the deflection angle is small

Over time, the general door will fall and the lock tongue will not be fully extended, and the oil on the factory will be dry. It is impossible for the user to adjust the height of the door and remove the lock on time. Over time, the rotating parts such as the handle and the lock tongue It will lose flexibility, in case the door is not reset when the door is closed and locked, it will not be possible to unlock and enter the house when you are outside
