Electronic signal transmission device for key cylinder

Abstract

The invention relates to the technical field of locks, and particularly relates to an electronic signal transmission device for a key cylinder. The electronic signal transmission device for the key cylinder comprises a key and a lock body, wherein the key cylinder, a shifting fork, a knob shaft and a coupling device which is used for enabling the key cylinder and the shifting fork to rotate in a coupling mode are arranged in the lock body, a signal sending module which is used for sending a signal to drive the coupling device to operate is arranged in the key, a conductive contact which is connected with a key rod is arranged on the key rod, after the key is inserted into the key cylinder, the conductive contact is connected with a key cylinder probe in the key cylinder, the key cylinder probe is connected with a left lock body probe in the lock body, the left lock body probe is connected with a right lock body probe in the lock body by virtue of a conductive sealing piece, the right lock body probe is connected with a conducting ring on the knob shaft, and the conducting ring is connected with a driving circuit of the coupling device. By adopting the technical scheme, the electronic signal transmission device has the advantages of compact overall structure and stability in connection, and the service life of a product is prolonged.

Description

technical field [0001] The invention relates to the field of electronic locks, in particular to an electronic signal transmission device for a lock cylinder. Background technique [0002] The innovation of science and technology has injected new vitality into the lock industry. With the improvement of people's material level and the increasing demand for security and confidentiality, traditional locks can no longer meet higher requirements for use. This requires various high-tech Features Recreate traditional locks, so that the improved locks can be extended and expanded in terms of security functions and uses. Electronic locks have become an indispensable part of the current security system with a high level of confidentiality, and its status and function cannot be replaced by traditional mechanical locks. Common electronic locks separate the lock cylinder and the shift fork set in the lock body, and then realize the connection and joint rotation of the lock cylinder and t...

AI Technical Summary

Problems solved by technology

If the key does not match, it is impossible to send the correct control signal to realize the function of driving the coupling device, and it is impossible to realize the effect of opening the lock

The space in the lock body is generally narrow, and the lock cylinder, shift fork and knob shaft must be rotated during work, so it is not only difficult for the wires to be ar
