Actuating motor unit for electronic lock

Abstract

The invention relates to an actuation motor set of an electronic lock. The actuation motor set comprises a fixed seat, a motor, a worm and a spring, wherein the fixed seat is provided with an accommodating chamber; the motor is connected with the fixed seat and is provided with a rotating shaft; the worm is connected to the rotating shaft, a tooth arranged on the worm is not completely extended to a boosting end and a reset end at two ends of the worm; and a sleeved part of the spring is bent to the worm to form a horizontal hook shape to be hooked on the tooth in a sleeving manner, the part, located outside the sleeved part, of the spring is a pushing and propping part, and the inner diameter of the pushing and propping part is larger than the outer diameter of the tooth. The spring can be spirally pushed by the tooth with the rotation of the worm and then moves forward and backward in the axial direction of the worm, when the spring moves to the boosting end of the worm, idling is formed due to absence of sleeved pushing of the tooth, and when the spring reversely moves to the reset end, the idling is also formed due to absence of sleeved pushing of the tooth, so that the overshoot phenomenon during driving of the actuation motor is prevented.

Description

technical field [0001] The present invention relates to an actuating motor group, in particular to an actuating motor group arranged in an electronic lock. Background technique [0002] General mechanical locks achieve the purpose of anti-theft that can only be opened by their exclusive keys through the configuration of the lock bolts in the lock core. However, such locks are often cracked by those who are interested in using special mechanical tools. Therefore, in order to further enhance the difficulty of unlocking the lock, there is an invention in the prior art that combines the electronic induction identification mechanism with the traditional mechanical lock, and achieves the best anti-theft function by means of mechanical and electronic double locking. [0003] Electronic lock structure in the prior art such as figure 1 As shown, it includes a lock core 20 , and the lock core 20 is connected with a clutch 30 , a cam 40 , an actuating motor group 50 and a knob core 6...

AI Technical Summary

Problems solved by technology

Therefore, the actuation mode and failure rate of the actuating motor group 50 deeply affect the use effect and life of the electronic lock.

The motor of the actuating motor group in the prior art is not provided with a proper limit mechanism when it rotates, so when the motor drives the connected components to move forward or backward, the component often overshoots and pushes to other components On the one hand, the motor often affects its service life due to overshoot, on the other hand, it is easy to cause other components to be pushed, resulting in displacement or poor contact of internal components, and the probability of failure of the electronic lock is quite high.

Although many prior art improved actuating motor sets were equipped with limit sensors and limit locking mechanisms, these components are relatively complex, so the manufacturing process has become more cumbersome, and because more components and electronic components are used , making the cost relatively higher and reducing the competitiveness of the product
