Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic clutches, and particularly relates to a dust-proof automotive air-conditioning electromagnetic clutch. Background Technique

[0002] The electromagnetic clutch in an automotive air-conditioning system is an important part of the air-conditioning system. It is responsible for connecting and disconnecting the transmission between the compressor and the engine, thereby controlling the opening and closing of the air-conditioning system. During the operation of the vehicle, the clutch body is easily invaded by impurities such as dust and sand grains due to being exposed to high temperature and dust environment for a long time. This will not only reduce the working efficiency of the clutch but also shorten its service life. Therefore, dust-proof design is crucial for improving the performance and reliability of the automotive air-conditioning electromagnetic clutch.

[0003] Traditional clutch designs often do not have a dedicated dust-proof structure, resulting in dust easily entering the clutch interior and accelerating the wear of internal parts. Due to the limitations of the dust-proof structure, some designs may neglect the heat dissipation requirements of the clutch body, leading to an increase in temperature and affecting the performance and life of the clutch. Existing dust-proof structures may be complex in design, and the process of disassembling and replacing dust-proof components is cumbersome, increasing the maintenance cost and difficulty. During vehicle operation, due to vibrations and other reasons, the dust-proof structure may shift or fall off, affecting the working efficiency and safety of the clutch.

[0004] In view of this, we propose a dust-proof automotive air-conditioning electromagnetic clutch. Content of the Utility Model

[0005] The technical problem to be solved by the present invention is that in the above-mentioned prior art, clutch designs often do not have a dedicated dust-proof structure, resulting in dust easily entering the clutch interior and accelerating the wear of internal parts.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A dust-proof automotive air-conditioning electromagnetic clutch includes a clutch body, a dust-proof cover, a cover plate, and a dust-proof filter screen;

[0008] The clutch body is installed on the compressor;

[0009] The dust-proof cover is arranged outside the clutch body and fixedly connected to the housing of the compressor. Two opening slots A for belt transmission are provided on the dust-proof cover;

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] The following combines the attached Figure 1-8 This application will be further described in detail.

[0037] The embodiment of this application discloses a dust-proof electromagnetic clutch for an automobile air conditioner, including a clutch body 1, a dust cover 3, a cover plate 4, and a dust filter 5;

[0038] The clutch body 1 is installed on the compressor 2;

[0039] The dust cover 3 is arranged outside the clutch body 1 and fixedly connected to the housing 21 of the compressor 2. Two open slots A31 for belt transmission are opened on the dust cover 3;

[0040] The cover plate 4 is butted on the outer side of the dust cover 3 and cooperates with the dust cover 3 to seal and dust-proof the clutch body 1. Two open slots B41 that are butted with the two open slots A31 and are for belt transmission are opened on the cover plate 4. The two open slots A31 and the two open slots B41 are butted to form two inlets and outlets 6 for belt transmission; This design ensures that the belt can pass through the clutch smoothly and be connected to the drive source (such as the engine), while maintaining the sealing performance of the dust cover 3. In this way, it not only protects the inside of the clutch from dust pollution but also does not affect the efficiency of belt transmission.

[0041] The casing 21 of the compressor 2 is equipped with a retaining ring consisting of an inner stepped ring 22 and an outer stepped ring 23. The outer stepped ring 23 is equipped with two symmetrically arranged mounting blocks A24 with holes. The dust cover 3 is equipped with a concave annular groove 32 that fits over and retains the outer sides of the inner and outer stepped rings 22 and 23, as well as two symmetrically arranged mounting blocks B33 with holes.

The retaining ring design helps to secure the position of the dust cover 3 and prevent it from shifting during operation. The symmetrical arrangement of the mounting blocks A24 and B33 with holes ensures a more secure installation and fixation, improving the stability and durability of the entire structure.

[0042] Four perforated mounting blocks C35 are arranged equidistantly around the outer surface of the dust cover 3. Perforated mounting blocks D48, which mate with the four perforated mounting blocks C35, are arranged equidistantly around the outer surface of the cover plate 4. The cover plate 4 is secured to the dust cover 3 via bolts B49 threaded through the perforated mounting blocks D48 and C35. The design of the perforated mounting blocks C35 and D48 ensures that the cover plate 4 is securely fixed to the dust cover 3, ensuring the sealing and stability of the overall structure.

[0043] An air inlet 42 for air intake into the clutch body 1 is provided on the cover plate 4 ; a dust filter 5 is magnetically attracted to the air inlet 42 of the cover plate 4 to filter the air entering the clutch body 1 .

[0044] The air inlet 42 on the cover plate 4 is divided into four arc-shaped air outlets by a cross-shaped bracket 43 in the center of the cover plate 4. An annular concave groove 44 is provided on the cover plate 4 and located outside the four arc-shaped air outlets.
