Isolated electronic lock drive structure

Abstract

The invention discloses an isolated type electronic lock driving structure, which includes a housing, in which an execution chamber and an electric control chamber are arranged, the execution chamber communicates with the electric control chamber through a through hole, and there are mutually rotating locks in the execution chamber. Cooperating actuators I and II have blind holes corresponding to the through holes on the actuator II, and rubber caps are installed in the electric control chamber, and the rubber caps are fixed at one end of the through holes. The coaxial pin with the through hole has a counterbore corresponding to the through hole on the actuator, a second spring is arranged on the counterbore section of the counterbore, and a linkage pin is arranged in the counterbore. Through the deformable characteristics of the rubber cap, the pin is controlled to move in a straight line along the axial direction of the through hole, and then it is linked with the linkage pin to finally realize the control of the movement of the actuator in the actuator chamber, so as to improve the intelligence of the electronic lock. At the same time, it avoids damage to the executive parts caused by insensitive response in the existing electronic lock.

Description

technical field [0001] The invention relates to the field of intelligent electronic locks, in particular to an isolated electronic lock driving structure. Background technique [0002] In the existing technology, it is suitable for smart electronics with harsh conditions such as no power supply, wide temperature range (-20°C to +60°C), high humidity (even soaked in water), sediment, corrosion, vibration, and large electromagnetic interference in the working environment. Lock, due to the high protection level (IP68) and the high anti-destructive ability requirements, so the current solution is to separate the structure of electronic control and mechanical parts to meet the requirements of protection level up to IP68; the existing intelligent electronic lock The electromagnet is used in the drive mechanism of the product, which has the disadvantages of poor anti-vibration performance and high power consumption. Since the electronic control module and the mechanical action modu...

Problems solved by technology

In the prior art, the electronic control module and the mechanical action module of the intelligent electronic lock with a protection level of IP68 are mutually independent structures, and the driving part of the mechanical action module uses an electromagnet, which makes the electronic lock have poor anti-vibration performance and high power consumption. In addition, the electromagnet is prone to insensitivity during operation, which leads to the loss of the unlocking function, so that the failure rate of the electronic lock remains high; in view of such defects, the inventor redesigned the drive mechanism of the existing electronic lock, that is A through hole is opened between the originally independent executive chamber and the electric control chamber to realize the linkage of the mechanical actions of the two. At the same time, under the premise of ensuring the air isolation between the executive chamber and the electric The rubber cap seals one end of the through hole, so that the electronic control chamber is isolated from the outside, and through the deformable characteristics of the rubber cap, the pin is controlled to move linearly along the axial direction of the through hole, and then it is linked with the linkage pin to finally realize Control the movement of actuators Ⅰ and Ⅱ in the execution chamber to improve the intelligence of the electronic lock, and at the same time avoid damage to the actuators caused by the insensitive response in the existing electronic locks
