Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In one embodiment, a magnetic lock with a voice prompt function is provided, as shown in fig. 1 to 8, including a lock body 1 for adsorption, the lock body including a housing 2, and a PCB 21, an infrared sensing device 22, and an electromagnet assembly 23 disposed inside the housing and connected by a wire; wherein, the PCB board is provided with a voice prompt module; the PCB is used for controlling the power-on state of the electromagnet assembly according to the monitoring signal of the infrared sensing device and driving the voice prompt module to work.

The lock body adsorbs with the metal sheet under the circular telegram condition, realizes the locking function, and its theory of operation is: when a user enters or moves out of the monitoring range of the infrared sensing device, the infrared sensing device sends a monitoring signal to the PCB to inform a control unit of the PCB to perform corresponding operation; the PCB controls the current on-off, the size and the like of the electromagnet assembly to realize unlocking and locking; meanwhile, the voice prompt module sends corresponding prompt tones to the user, such as 'the door is opened', the state of the door lock is convenient to know, and the efficiency of the automation of the public place personnel control access control is effectively improved.

Furthermore, a delay control module is integrated on the PCB and used for controlling the lock body to be automatically locked after a preset time; namely, the user can flexibly set the delay time of 0, 3, 6, 9 seconds and the like according to the requirement so as to adapt to the fire door or the card reader needing to be delayed to be closed, and meanwhile, the fire door or the card reader can be conveniently and directly controlled to be automatically locked after the door is opened from the inside.

Further, the shell is provided with an LED lamp 7 connected with the PCB, namely, the locking and unlocking states of the magnetic lock are known through the color change of the LED lamp, and the red lamp locking and the green lamp unlocking or the red lamp unlocking and the green lamp locking can be flexibly selected according to the requirement.

Structurally, the electromagnet assembly (i.e. magnetic lock cylinder) comprises a coil assembly 231, a hall switch (not visible in the figure), a potting assembly and a silicon steel sheet 232 with slot positions. Wherein, the silicon steel sheet is of an E-shaped structure; the coil assembly comprises a copper wire and a bracket corresponding to the E-shaped silicon steel sheet groove position, the copper wire is wound around the bracket through a winding machine to form an appointed number of turns and then is connected with a lead, and the appointed number of turns is determined according to the working current required by the electromagnet assembly to generate corresponding magnetic force; the encapsulation assembly is used for accommodating silicon steel sheets.

Specifically, the coil assembly is pressed into a slot position of the E-shaped silicon steel sheet, then the coil assembly and the Hall switch are placed into the encapsulation assembly together for glue filling, epoxy resin A/B glue is filled, gaps between the A/B glue and the encapsulation assembly are filled with the A/B glue, and the lock core in the required shape is formed after solidification.

The working principle of the electromagnet assembly is as follows: the Hall switch is used for monitoring and feeding back the locking and unlocking states of the magnetic lock. When the magnetic lock is attracted with the suction plate, magnetic force is generated, and the Hall switch is triggered to feed back a locking signal; when the magnetic lock and the suction plate are not attracted, the Hall switch is not triggered, and an unlocking signal is fed back. Wherein, the factory setting of the magnetic lock is a group of lock state signals: NO, NC and COM contact output are convenient for the Hall switch to detect the feedback of the state of the door lock in real time, so that the security system is safer and more effective. The magnetic lock has strong suction force, the maximum tension can reach 280 kilograms, and the magnetic lock is firm and safe.
