Technical Field
The invention relates to the technical field of intelligent locks, in particular to a lock body positioning device.
Background
Along with the development of the intelligent home technology, the intelligent lock needs to provide timely feedback of the state of the door lock of a remote user. But the smart lock processor also needs the state information to drive or operate. The acquisition of these status information is determined by monitoring the position information of the associated movable parts of the door lock for locking or unlocking. This requires an information design module that can monitor and send out positional information or positioning of these moving parts.
The common design modules on the market at present are realized by adopting a tact switch or a photoelectric switch. Both of these solutions suffer from significant drawbacks. For the scheme of realizing the touch switch, the movable part (sliding block) needs to perform one-time contact mechanical extrusion on the touch switch every time the movable part outputs positioning information. The design scheme often has the defects that the service life cannot be guaranteed, the failure rate is high, and the use experience of customers is poor. The photoelectric switch positioning design scheme has the characteristics of high power consumption and dust resistance. The installation environment of the intelligent lock often cannot meet the requirement of no dust. Therefore, the scheme adopting the photoelectric switch design has short service time and more faults in the case of generally adopting the intelligent lock powered by the battery and a relatively complex service environment.
At present, magnets and Hall devices are rarely adopted in the market for carrying out the design, and the positioning accuracy of the conventional design scheme is difficult to realize the specified requirement, so that the effective control and the state detection cannot be carried out.

The preferred embodiment:
as shown in fig. 8, in an intelligent lock body using the lock body positioning device provided by the present invention, a main lock tongue, a detection tongue, and a two-way tongue are all required state detection movable mechanisms. Each latch has a magnet assembly secured thereto. Hall devices are respectively arranged at positions, which need to be positioned, of the circuit board on the movement routes of the three lock tongues. Hall devices are respectively arranged at the positions where the lock tongues pop up and are positioned on the circuit board on the movement routes of the two-way tongue and the detection tongue. Hall devices are respectively arranged at two corresponding positions of the circuit board on the movement route of the main bolt, wherein the bolts are popped out and completely retracted and positioned. When a user pushes the door to lock, the detection tongue is pressed in, and the corresponding magnet assembly leaves the corresponding Hall device; meanwhile, the bidirectional tongue is pressed in and then popped up, and the corresponding magnet assembly returns to the corresponding position after leaving the corresponding Hall device. The detection tongue leaves the Hall device to cause a Hall device triggering signal to be transmitted to the circuit board processor, meanwhile, the detection tongue leaves the corresponding Hall device and returns to two signals triggered by the corresponding position to be transmitted to the circuit board processor, the circuit board processor determines that the door is moved to a correct closing position by a user through judgment, then the main spring bolt is driven to move to a fully retracted position through the gearbox, and whether the main spring bolt is locked in place is judged through the Hall device at the fully retracted position of the main spring bolt on the circuit board.
