Abstract

The invention provides a technology for detecting insertion of a foreign body in an intelligent lock cylinder based on a Hall switch technique. The device for detecting the insertion of the foreign body in the lock cylinder comprises a magnetic steel upper tumbler, a common lower tumbler, a spring, a Hall switch hole, a Hall switch and a flexible printed circuit (FPC) module. When any foreign body is inserted into the lock cylinder for unlocking, the foreign body contacts tumblers of the lock cylinder, so that the magnetic steel upper tumbler, the common lower tumbler and the spring move; and when the magnetic steel upper tumbler moves to a detection range of the Hall switch, a signal that the foreign body is inserted and detected is generated. When the foreign body leaves the lock cylinder, the magnetic steel upper tumbler, the common lower tumbler and the spring restore the original states under the action of the spring; and when the magnetic steel upper tumbler moves to an undetected range of the Hall switch, a signal that the foreign body is not detected is generated. The technology has the smallest influence on the conventional mechanical lock cylinder structure; and the assembly is simple and reliable, the detection is sensitive and the power consumption is low.

Description

The foreign matter of intelligence lock core inserts detection technique

Technical field

The intelligent lock core foreign matter that the present invention is based on the honeywell switch sensor technology inserts detection method, and the foreign matter that the method can be applied to smart lock inserts detection.

Background technology

The lock core of existing residential houses security door has standard machinery lock, magnetic control lock, and the professional person can open door lock within several seconds or a few minutes, and anti-theft effect is poor.In order to protect home environment and property safety, lockset various intelligent locks occur constantly improveing and innovating, so that the robber is difficult to crack and destroy.At present existing intelligent lock core is little because be limited by the lock core volume, and baroque cause can't realize foreign matter is inserted the function that detects at lock core.Realize that at lock core foreign matter inserts detection technique very difficult, the present whole world of lock core that possesses the insertion of Intelligent Measurement foreign matter is all blank.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structure, easy to operate, the lock core of low-power consumption detects the method that foreign matter inserts, and in time export foreign matter and insert information, whether there is foreign matter to insert, possesses more intelligent anti-theft feature thereby allow smart lock detect in the time the earliest.

The present invention is achieved in that it comprises pellet on tapered end, FPC, key, Hall switch, spring, the magnet steel, common lower pellet.Its special character is: on the main body mechanism that does not change the existing machinery lock core and function basis, utilize the sensor technology of Hall switch to realize that foreign matter inserts detection.The sidewall of the correspondence of pellet digs the dark groove of 1mm on the magnet steel of tapered end right output port, and the large I of groove length and width is processed according to the FPC dimensional requirement, is used for placing the FPC with honeywell switch sensor.The breach that can place honeywell switch sensor is opened in the lower right of pellet on the magnet steel that needs corresponding below the groove detect.Upper pellet to lock core magnetizes processing, makes it to become pellet on the magnet steel.When pellet and spring on common lower pellet, the magnet steel were subject to foreign matter insertion extruding, pellet moved downward near honeywell switch sensor on the magnet steel, honeywell switch sensor output detections information.

Advantage of the present invention is the 26S Proteasome Structure and Function that does not change the existing machinery lock core, and the use habit and the user that also do not change the user experience, and be simultaneously simple in structure, easy to operate, so that the scalable replacement of standard machinery lock core is safer intelligent lock core.When door lock was by improper opening, warning information can send to household intelligent system, by household intelligent system warning information was sent to the mobile phone of home owner, the security system of residential quarter.

Hall switch (A), magnet steel (C) and the magnetic line of force (E).

Specific implementation method

The foreign matter of intelligence lock core inserts detection method, enforcement is characterised in that the side of spring (B) is provided with Hall switch (A) and FPC (2), the groove that is fit to FPC (2) is dug out in the relevant position of lock core sidewall simultaneously, and the hole of the position of suitable Hall switch (A).The intelligence lock core adopts the Hall switch (A) of super low-power consumption, guarantees that intelligent lock core is the product of super low-power consumption.

Intelligence lock core foreign matter does not insert state: foreign matter or key (3) be not when entering lock core, and pellet on the magnet steel (C) and common lower pellet (D) are upspring by spring (B).Pellet on the magnet steel (C) is away from Hall switch (A), and the magnetic line of force (E) does not pass Hall switch (A), and Hall switch (A) does not detect the motion of pellet on the magnet steel, and Hall switch output does not detect the information that foreign matter inserts.

Intelligence lock core foreign matter inserts state: foreign matter or key (3) are when entering lock core, and spring (B) is by pellet (C) extruding under foreign matter or key (2) and common lower pellet (D) and the magnet steel.Move to its magnetic line of force (E) on the magnet steel (C) and pass Hall switch (A), Hall switch (A) is determined with accordingly foreign matter and inserts.
