Problems solved by technology
[0002] With the advancement of science and technology, the lock industry has also developed rapidly. The application range of electronic locks and smart locks is becoming wider and wider, and they are more and more popular in daily life. Now the control method of these locks on the market is usually motor rotation. The rear pin clamp pushes the spring to compress to realize the clutch. At this time, there will be contact wear between the motor stator and the probe brush and damage to the spring due to repeated friction and compression. There is a problem with the core components of the lock, the lock cannot be used and it is difficult to maintain, and the lock needs Maintain power supply status for a long time, while locks are usually powered by 5# batteries, the power consumption is fast, and the user experience is poor

The invention discloses an electromagnetic clutch. The electromagnetic clutch comprises a shell. A chamber is arranged in the shell. An electromagnetic fixed box is fixedly connected with the inner wall of the chamber. An opening is formed in the top of the electromagnetic fixed box. A coil is arranged in the electromagnetic fixed box. An electromagnetic core sealing plate is fixedly arranged at the position of the opening. A magnet is arranged between the electromagnetic core sealing plate and the coil. A through channel is formed in the middle of the coil in the central axis of the coil. A shaft sleeve is arranged in the through channel. The top end of the shaft sleeve penetrates out of the magnet, the electromagnetic core sealing plate and the top surface of the shell. A reset spring isarranged on the outer side of the shaft sleeve in a sleeving connection manner. A shaft shoulder is arranged at the top end of the shaft sleeve. A clutch supporting plate is connected with the top end of the shaft sleeve. The electromagnetic clutch is in noncontact transmission, mutual friction between structures in motion is reduced, the usage power consumption is reduced, the service life is prolonged, and the performance is more stable.
