Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, and in particular to an electromagnetic clutch structure for automotive air conditioning. Background Technology

[0002] The automotive air conditioning system is a key component in enhancing driving comfort in modern vehicles, and its core component, the compressor, is typically controlled by an electromagnetic clutch. Traditional automotive air conditioning electromagnetic clutches mainly consist of a pulley assembly mounted on the compressor input shaft, a pressure plate, and a coil that generates electromagnetic attraction. However, existing automotive air conditioning electromagnetic clutch structures still suffer from poor protection capabilities, failing to effectively prevent dust and impurities from damaging the pulleys and clutch.

[0003] Therefore, it is essential to invent an electromagnetic clutch structure for automotive air conditioning. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an automotive air conditioning electromagnetic clutch structure, which solves the problem that existing automotive air conditioning electromagnetic clutch structures still have poor protection capabilities and cannot effectively prevent dust and impurities from damaging the pulley and clutch. An automotive air conditioning electromagnetic clutch structure includes a compressor, a support housing, a mounting bracket, a clutch structure, a drive belt, and a clutch protection structure, wherein: the support housing is fixedly installed on the outside of the compressor, and the mounting bracket is fixedly installed on the outside of the compressor; the clutch structure is installed at one end of the compressor; the drive belt engages with the outside of the clutch structure, and the clutch protection structure is fixedly installed on the outside of the support housing.

[0005] The clutch structure includes a support plate, a pressure plate, an electromagnetic structure, and a meshing pulley. The support plate is rotatably mounted on one end of the compressor, and the electromagnetic structure is installed inside the support plate. The pressure plate is fixedly mounted on the electromagnetic structure, and the meshing pulley is fixedly mounted on the outside of the support plate.

[0006] The clutch protection structure includes an extended support frame, a support bracket, a protective box, a mounting plate, and a positive pressure structure. The extended support frame is fixedly installed on the outside of the support housing, and the support bracket is fixedly installed on the outside of the extended support frame. The protective box is fixedly installed at one end of the support bracket and covers the outside of the clutch structure. The mounting plate is fixedly installed on the surface of the protective box. The positive pressure structure is fixedly installed on the surface of the mounting plate.

[0007] The meshing pulley inside the clutch structure adopts a ring-shaped steel metal structure, and the meshing pulley can be fixedly installed on the outside of the support plate by bolts. The meshing pulley can be installed or removed from the outside of the support plate; the contact surface between the meshing pulley and the drive belt is provided with anti-slip patterns.

[0008] The protective box inside the clutch protective structure is a ring-shaped steel metal box, and a dust discharge gap is left between the protective box and the clutch structure. The protective box and the clutch structure do not contact each other. The positive pressure structure can input air into the interior of the protective box, and the generated high pressure can be discharged outward from the gap between the protective box and the clutch structure.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The clutch structure of this utility model can control the power supply of the compressor through electromagnetic principles. When the electromagnetic structure is energized, it attracts the pressure plate to engage with the meshing pulley driven by the drive belt, transmitting power to the compressor. The meshing pulley is bolted to the support plate, making it easy to replace or maintain independently. Furthermore, the anti-slip pattern on the contact surface between the meshing pulley and the drive belt ensures efficient and reliable power transmission.

[0011] The clutch protection structure of this utility model is designed to fix and cover the annular protective box to the outside of the clutch structure by extending the support frame and support bracket, forming a basic isolation space. The key dust removal function is accomplished by the positive pressure structure, which can continuously input air into the protective box to form a positive pressure higher than the outside, so that clean air can be evenly discharged outward from the gap between the protective box and the clutch structure. This "air curtain" can not only blow away foreign objects, but its outward flow characteristics also facilitate the disassembly and dissipation of internal heat, fundamentally preventing the intrusion of pollutants.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As attached Figure 1 To be continued Figure 4 As shown.

[0020] This utility model provides an electromagnetic clutch structure for an automotive air conditioner, comprising a compressor 1, a supporting housing 2, a mounting bracket 3, a clutch structure 4, a drive belt 5, and a clutch protection structure 6, wherein: the supporting housing 2 is fixedly installed on the outside of the compressor 1, and the mounting bracket 3 is fixedly installed on the outside of the compressor 1; the clutch structure 4 is installed at one end of the compressor 1; the drive belt 5 engages with the outside of the clutch structure 4, and the clutch protection structure 6 is fixedly installed on the outside of the supporting housing 2.

[0021] The clutch structure 4 includes a support plate 41, a pressure plate 42, an electromagnetic structure 43, and a meshing pulley 44. The support plate 41 is rotatably mounted on one end of the compressor 1, and the electromagnetic structure 43 is mounted inside the support plate 41. The pressure plate 42 is fixedly mounted on the electromagnetic structure 43, and the meshing pulley 44 is fixedly mounted on the outside of the support plate 41.

[0022] The clutch protection structure 6 includes an extended support frame 61, a support frame 62, a protective box 63, a mounting plate 64, and a positive pressure structure 65. The extended support frame 61 is fixedly installed on the outside of the support housing 2, and the support frame 62 is fixedly installed on the outside of the extended support frame 61. The protective box 63 is fixedly installed on one end of the support frame 62 and covers the outside of the clutch structure 4. The mounting plate 64 is fixedly installed on the surface of the protective box 63. The positive pressure structure 65 is fixedly installed on the surface of the mounting plate 64.

[0023] The meshing pulley 44 inside the clutch structure 4 adopts a ring-shaped steel metal structure, and the meshing pulley 44 can be fixedly installed on the outside of the support plate 41 by bolts. The meshing pulley 44 can be installed or removed on the outside of the support plate 41; the contact surface between the meshing pulley 44 and the drive belt 5 is provided with anti-slip pattern.

[0024] The protective box 63 inside the clutch protective structure 6 is a ring-shaped steel metal box, and a dust discharge gap is left between the protective box 63 and the clutch structure 4. The protective box 63 and the clutch structure 4 do not contact each other. The positive pressure structure 65 can input air into the interior of the protective box 63, and the generated high pressure can be discharged outward from the gap between the protective box 63 and the clutch structure 4.

[0025] The core working principle of this automotive air conditioning electromagnetic clutch structure 4 is electromagnetic drive and power separation. When the air conditioning system is started, the electromagnetic structure 43 in the clutch structure 4 is energized to generate magnetic force, attracting the pressure plate 42 to tightly engage with the meshing pulley 44 driven by the drive belt 5; the anti-slip pattern on the contact surface of the meshing pulley 44 effectively prevents slippage, and the power is reliably transmitted to the compressor 1 through the support plate 41, enabling it to start working. When the air conditioning is turned off, the electromagnetic structure 43 is de-energized, the magnetic force disappears, the pressure plate 42 separates from the meshing pulley 44, the meshing pulley 44 resumes idling, and the compressor 1 stops running. The meshing pulley 44 is bolted to the support plate 41, facilitating replacement after wear, reflecting a design that allows for easy disassembly.

[0026] Throughout operation, the clutch protection structure 6 provides continuous active protection. Its positive pressure structure 65 introduces air into the protective housing 63 via the mounting plate 64, creating positive pressure. The protective housing 63 is fixedly supported by the extended support frame 61 and the support bracket 62, and covers the outside of the clutch structure 4. The high-pressure clean air inside is discharged outwards through the gap between the protective housing and the clutch structure 4, forming an air curtain barrier that effectively prevents external dust and moisture from intruding, thereby protecting the delicate clutch structure 4 and extending its service life. The entire device is stably mounted on the compressor 1 via the mounting bracket 3 and the support housing 2.

[0027] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
