[0002] The electromagnetic clutch of automobile air conditioner is a power transmission device between automobile engine and automobile air conditioner compressor. Automobile air conditioner compressor is driven by automobile engine through electromagnetic clutch. The existing electromagnetic clutch of air conditioner has certain disadvantages when used. Because there is a gap between pressure plate and pulley, dust will enter the inside when they fit together, which will cause dust to accumulate inside electromagnetic clutch.

[0003] China Patent Authorization Announcement Number: CN 216519282 U, Authorization Announcement Date May 13, 2022. This utility model relates to an automobile air-conditioning electromagnetic clutch with dustproof function, including a pulley, a coil assembly is fixed on the inner wall of one end of the pulley, and a connecting shaft is fixed on the outer wall of one side of the coil assembly, and the end of the connecting shaft away from the coil assembly is connected to a pressure plate, and a first sealing groove is opened on the outer wall of one side of the pulley, a first sealing ring is provided outside the first sealing groove, and a second sealing ring is bonded to the outer wall of the side of the pressure plate close to the pulley, a second sealing groove is opened inside the second sealing ring, and a fixed disk is fixed on the pressure plate through a leaf spring. The disadvantage of this technical solution is that the pressure plate and the pulley are separated when the pulley is not in operation, but dust is easily introduced during separation, resulting in dust accumulation and affecting the operation of the pulley.

[0004] In summary: the automobile air-conditioning electromagnetic clutch has the disadvantage of low dust-proof effectiveness. Utility Model Content

[0005] The utility model aims to overcome the shortcoming of low dustproof effect of automobile air-conditioning electromagnetic clutch in the prior art and provides a dustproof type electric automobile air-conditioning clutch with high dustproof effect.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

At the same time, when in use, the dustproof net is folded to keep the fixed ring 2 at the joint of the pressure plate and the pulley to prevent dust from entering. Among them, in the structure where the diameter of the pressure plate is smaller than the diameter of the pulley, the elastic force keeps the fixed ring 2 always against the surface of the pulley to fully fold the dust, and when the diameters of the pressure plate and the pulley are the same, the dustproof net does not need to be folded and directly covers the connection to fully block the dust, thereby having strong applicability and does not affect the fitting area of ​​the pressure plate and the pulley, ensuring the strength of the strong fit between the structures and the synchronization of operation. It achieves the effect of improving the convenience and stability of structural connection, facilitating later maintenance, and having a strong and comprehensive dustproof effect to ensure the stability of clutch operation.

The end faces of the positioning ring 1 and the positioning ring 2 are both provided with positioning grooves, and the cross-sectional shape of the positioning grooves is stepped. The positioning grooves include groove surface 1 and groove surface 2, and the end of the dustproof net is connected to groove surface 1. The positioning ring 1 and the positioning ring 2 locate the position of the dustproof net through groove surface 1, so that the position of the dustproof net connection is more accurate and the dustproof net is prevented from shifting and twisting. The installation efficiency and stability of the structure are improved.

One end of the spring is connected to the second groove surface of the first positioning ring, and the other end is connected to the second positioning ring, so that the elastic force of the spring drives and supports the second fixing ring to abut against the end surface of the pulley and automatically reset the second fixing ring, thereby achieving the effect of improving the smoothness of the structural operation.

[0012] Preferably, the spring is placed inside the dustproof net. The spring is placed inside the dustproof net, which can support the dustproof net, organize the dustproof net and prevent it from entering between the pressure plate and the pulley to affect the clutch operation, thereby ensuring the stability of the dustproof operation.

[0013] Preferably, the fixing ring 1 is provided with a guide hole, the fixing ring 2 is provided with a guide rod, one end of the guide rod is connected to the fixing ring 2, and the other end of the guide rod is plugged into the guide hole.
