Electrically controlled intelligent key for magnetically coded lock

Abstract

The invention discloses an electrically controlled intelligent key for a magnetically coded lock, and aims to provide the electrically controlled intelligent key for the magnetically coded lock with high safety, good reliability and electric control intellectualization. The key comprises a key skeleton (1) and a key rod (2) connected fixedly, wherein the exterior of the key rod (2) is provided with an unlocking convex part (21), the interior of the key rod (2) is provided with a through hole, the through hole is matched with a linkage rod (3), one end of the linkage rod (3) extends into the key skeleton (1), and the linkage rod (3) is matched with a linkage gear (4); an intelligent circuit device, a step motor (5) and a battery are arranged in the key skeleton (1); the step motor (5) and the battery are electrically connected with the intelligent circuit device; the output shaft of the step motor (5) is matched with an output gear (51), and the output gear (51) is engaged with the linkage gear (4); and the linkage rod (3) is provided with at least two magnet holes (31) which mutually form an angle, and unlocking permanent magnets (32) are matched in the magnet holes (31). The invention can be widely applied in the field of electrically controlled intelligent keys for the magnetically coded locks.

[0002] With the advancement of science and technology, the application of magnetic coded locks in the field of locks is becoming more and more extensive. The technology of magnetic coded locks continues to develop and mature. For example, the Chinese invention patent application with application number 200920040973.7 provides a magnetic coded lock that can withstand harsh environments. core and magnetic coded padlock, and the key used in conjunction with this magnetic coded lock core and padlock is the key for magnetic coded lock. There is an unlocking magnet on the top of the key rod. The unlocking principle of the key for the magnetic coded lock is to use the unlocking magnet on the key rod to attract the list in the magnetic coded lock cylinder to the unlocking position, thereby releasing the limit to the lock cylinder and making the lock cylinder It can be rotated in a circle to achieve the purpose of unlocking. However, the unlocking magnet of the existing key for magnetically encoded locks with the above structure is fixed, so the unlocking magnet is in the unlocking position from the beginning to the end. Anyone who has the key can unlock the lock. The key is easy to be imitated, which reduces the security, and even makes the lock lose its proper function, and anyone who gets the key can unlock the lock, which will easily lead to irregular management and unclear unlocking authority, especially in some special In an environment such as a power system, access control management is still important, and there is strict authority control. It is difficult for ordinary keys for magnetically encoded locks to ensure effective and reliable control of authority. On the other hand, the existing keys for magnetically encoded locks Can not achieve any electronic control and intelligent operation,

[0003] In summary, the existing magnetically encoded locks have technical defects such as low security, poor reliability, and inability to realize intelligent operation of keys.
