A passive electronic lock cylinder with automatic locking and its key

Abstract

The invention relates to an electronic lock without an external power source, and discloses a passive electronic lock cylinder with an automatic locking function. The passive electronic lock cylinder comprises a lock cylinder body (1), an electric control gear (2), a drive control device (3) and a locking device (4). A conductive communication contact (1-2) of the lock cylinder body (1) and the lock cylinder body (1) are connected with a positive electrode power source and a negative electrode power source respectively, the power sources control a driving motor (2-2) to rotate through an electric control circuit board (2-1) of the electric control gear (2), and a cam (2-3) is driven to control the stretching function of a locking elastic piece (4-1) so that the opening state and the locking state of the electronic lock cylinder can be controlled. Meanwhile, the invention further discloses a key for opening the electronic lock. The electronic lock and the key have good stability, safety and control performance, meanwhile, a circuit and a communication line are combined into one, the design is simple, ingenious and reasonable, the manufacturing size of the lock cylinder can be decreased, and the lock cylinder is suitable for electronic locks with smaller sizes.

Description

technical field [0001] The invention belongs to the field of electronic locks, and relates to an electronic lock without external power supply. technical background [0002] At present, passive electronic locks, such as the patent No. "200810109826.6" disclosed by the State Intellectual Property Office, "micro-power passive electronic lock head", the electronic lock of this patent is controlled by a circuit connected to the three electrodes of the electronic key, and the stroke The switch and the positioning switch use the photoelectric reflection principle to sense the spherical and concave surface of the locking spring to open and close the lock. It can be seen that the locking springs of the electronic lock are locked and locked by electronic circuit control of the cam rotation. Therefore, the passive electronic lock with this structure has the following defects: 1. The performance is unstable, and its photoelectric reflection function is easily affected by the quality pr...

[0002] At present, passive electronic locks, such as the patent No. "200810109826.6" disclosed by the State Intellectual Property Office, "micro-power passive electronic lock head", the electronic lock of this patent is controlled by a circuit connected to the three electrodes of the electronic key, and the stroke The switch and the positioning switch use the photoelectric reflection principle to sense the spherical and concave surface of the locking spring to open and close the lock. It can be seen that the locking springs of the electronic lock are locked and locked by electronic circuit control of the cam rotation. Therefore, the passive electronic lock with this structure has the following defects: 1. The performance is unstable, and its photoelectric reflection function is easily affected by the quality problems of the travel switch and the positioning switch, resulting in the lack of lock performance; 2. Safety performance Poor, it is easy to cause the cam rotation angle to be insufficient, causing the locking spring to fail to lock, posing a safety hazard
