Description

Technical Field

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

[0002] The automotive air conditioning system is a key component in enhancing the driving comfort of modern vehicles. Its core component, the air conditioning compressor, typically draws power from the engine via an electromagnetic clutch and drive belt. However, the engine's operating conditions are complex and variable, and the resulting vibrations are transmitted to the electromagnetic clutch and air conditioning compressor via the drive belt. Furthermore, the compressor's own periodic intake and exhaust cycles also generate significant vibrations. These vibrations are ultimately transmitted to the vehicle's frame through the mounting bracket, leading to increased interior noise and abnormal rattles, severely impacting NVH performance and reducing ride comfort. However, existing shock-absorbing mounts for automotive air conditioning electromagnetic clutches still suffer from limitations in providing adequate vibration damping and failing to specifically dampen multiple locations.

[0003] Therefore, it is very necessary to invent a shock-absorbing base for an electromagnetic clutch for automotive air conditioning. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a shock-absorbing base for an automotive air conditioning electromagnetic clutch, solving the issues that existing shock-absorbing bases for automotive air conditioning electromagnetic clutches still cannot provide adequate shock absorption and cannot specifically dampen multiple locations. A shock-absorbing base for an automotive air conditioning electromagnetic clutch includes an air conditioning compressor, a mounting bracket, a shock-absorbing base, an electromagnetic clutch, a drive belt, and a clutch shock-absorbing seat. The mounting bracket is fixedly installed on the outside of the air conditioning compressor and also fixedly installed inside the vehicle body. The shock-absorbing base is fixedly installed on the surface of the air conditioning compressor. The electromagnetic clutch is installed at the front end of the air conditioning compressor, and the drive belt engages with the outside of the electromagnetic clutch. The clutch shock-absorbing seat is fixedly installed above the shock-absorbing base.

[0005] The shock absorber base includes a vehicle body connecting plate, a buffer base plate, a support frame, an equipment mounting bracket, and an extension support base. The vehicle body connecting plate is fixedly installed inside the vehicle body, and the buffer base plate is fixedly installed on the inner surface of the vehicle body connecting plate. The support frame is fixedly installed at one end of the buffer base plate, and the equipment mounting bracket is fixedly installed at the upper end of the support frame. The extension support base is fixedly installed on the surface of the buffer base plate near the end of the vehicle body connecting plate.

[0006] The clutch damping seat includes a buffer plate, a support turntable, a first support wheel and a second support wheel, and the buffer plate is fixedly installed above two sets of extended support seats. The support turntable is fixedly installed at one end of the two sets of buffer plates. The first support wheel and the second support wheel are respectively rotatably installed on the two sets of support turntables.

[0007] The body connecting plate inside the shock absorber base is made of a steel metal plate, and the buffer base plate is made of two parallel steel plates. The buffer base plate will bend and deform after dissipating pressure. The equipment mounting bracket and extension support are connected to the air conditioning compressor as a whole.

[0008] The first and second support wheels inside the clutch damping seat are two sets of steel metal wheels with rubber sleeves on the outside. The first support wheel is located inside the gap between the electromagnetic clutch and the drive belt and only contacts the electromagnetic clutch. The second support wheel is located outside the electromagnetic clutch and the drive belt and only contacts the drive belt.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The shock-absorbing base of this utility model is fixed to the vehicle body through the vehicle body connecting plate and supported by the air conditioning compressor body through the equipment mounting bracket. The unique structure inside, consisting of a buffer base plate and a support frame, can effectively absorb and isolate the vibration from the air conditioning compressor and electromagnetic clutch by utilizing the elastic bending deformation of the buffer base plate. At the same time, it provides an installation base for the clutch shock absorber through the extended support base, which together play a key role in shock absorption, noise reduction, support and stability.

[0010] The clutch damping seat of this utility model is installed on the extension support seat of the damping base through a buffer plate, and targeted damping is achieved by using the first and second rotatable support wheels on the support turntable: the first support wheel extends into the gap between the electromagnetic clutch and the drive belt, and directly contacts the side of the pulley of the electromagnetic clutch to suppress its radial runout; the second support wheel presses against the outside of the drive belt, and the elasticity of the rubber sleeve tensions the belt and suppresses its vibration and noise, thereby jointly improving the smoothness and quietness of the system transmission.

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.

[0015] As attached Figure 1 To be continued Figure 2 As shown.

[0016] This utility model provides a shock-absorbing base for an automotive air conditioning electromagnetic clutch, comprising an air conditioning compressor 1, a mounting bracket 2, a shock-absorbing base 3, an electromagnetic clutch 4, a drive belt 5, and a clutch shock-absorbing seat 6. The mounting bracket 2 is fixedly installed on the outside of the air conditioning compressor 1 and also fixedly installed inside the vehicle body. The shock-absorbing base 3 is fixedly installed on the surface of the air conditioning compressor 1. The electromagnetic clutch 4 is installed at the front end of the air conditioning compressor 1, and the drive belt 5 engages with the outside of the electromagnetic clutch 4. The clutch shock-absorbing seat 6 is fixedly installed above the shock-absorbing base 3.

[0017] The shock absorber base 3 includes a vehicle body connecting plate 31, a buffer base plate 32, a support frame 33, an equipment mounting bracket 34, and an extension support base 35. The vehicle body connecting plate 31 is fixedly installed inside the vehicle body, and the buffer base plate 32 is fixedly installed on the inner surface of the vehicle body connecting plate 31. The support frame 33 is fixedly installed at one end of the buffer base plate 32, and the equipment mounting bracket 34 is fixedly installed at the upper end of the support frame 33. The extension support base 35 is fixedly installed on the surface of the buffer base plate 32 near the end of the vehicle body connecting plate 31.

[0018] The clutch damping seat 6 includes a buffer plate 61, a support turntable 62, a first support wheel 63 and a second support wheel 64, and the buffer plate 61 is fixedly installed above the two sets of extended support seats 35. The support turntable 62 is fixedly installed at one end of the two sets of buffer plates 61. The first support wheel 63 and the second support wheel 64 are respectively rotatably installed on the two sets of support turntables 62.

[0019] The body connecting plate 31 inside the shock absorber base 3 is made of a steel metal plate, and the buffer base plate 32 is made of two parallel steel plates. The buffer base plate 32 will bend and deform after relieving pressure. The equipment mounting bracket 34 and the extension support 35 are connected to the air conditioning compressor 1 as a whole.

[0020] The first support wheel 63 and the second support wheel 64 inside the clutch damping seat 6 are two sets of steel metal wheels with rubber sleeves on the outside. The first support wheel 63 is located inside the gap between the electromagnetic clutch 4 and the drive belt 5 and only contacts the electromagnetic clutch 4. The second support wheel 64 is located outside the electromagnetic clutch 4 and the drive belt 5 and only contacts the drive belt 5.

[0021] The air conditioning compressor 1, as the core of the cooling system, is powered by the engine, which is transmitted to the electromagnetic clutch 4 via the drive belt 5. The entire system is fixed to the vehicle body by the mounting bracket 2. The vibrations generated are first absorbed by the damping base 3: the body connecting plate 31 of the damping base 3 transmits the force to its buffer plate 32, which dissipates most of the low-frequency vibrations from the air conditioning compressor 1 through its own bending deformation. At the same time, the clutch damping seat 6, specially designed for the transmission system, begins to work. Its first support wheel 63 directly abuts against the pulley of the electromagnetic clutch 4, restricting its axial and radial movement, while the second support wheel 64 presses against the outer side of the drive belt 5, using the elasticity of its rubber sleeve to tension the belt and suppress slapping and shaking, thereby neutralizing the high-frequency impacts and noise generated when the electromagnetic clutch 4 engages and disengages. The damping base 3 and the clutch damping seat 6 work together to achieve multi-stage, efficient vibration damping, ensuring the smooth, quiet, and reliable operation of the automotive air conditioning system.

[0022] 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.
