Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a pulley structure for an automotive air conditioning compressor. Background Technology

[0002] The automotive air conditioning compressor pulley is a key power transmission component in the automotive air conditioning system. It is connected to the engine crankshaft via a belt, transmitting the engine's power to the air conditioning compressor to drive the refrigeration system.

[0003] However, in the existing automotive air conditioning compressor pulley structure, since the pulley is sleeved outside the coil assembly, heat accumulates in the coil assembly during operation. Although there are corresponding ventilation holes on the pulley, the ventilation hole area is limited and cannot achieve efficient heat dissipation.

[0004] Therefore, it is essential to invent a high-ventilation automotive air conditioning compressor pulley structure. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution for an automotive air conditioning compressor pulley structure: an automotive air conditioning compressor pulley structure, including a hollow pulley disc, a hollow support plate and a shaft cylinder, wherein: the hollow pulley disc is coaxially sleeved on the outside of the hollow support plate, and a plurality of I-beams and a plurality of sets of blades are arranged between the inner circumferential surface of the hollow pulley disc and the outer circumferential surface of the hollow support plate;

[0006] The outer circumferential surface of the hollow wheel is provided with a belt groove;

[0007] The hollow wheel disc has several sets of ventilation slots evenly distributed throughout its circumference. Each set of ventilation slots is located between two adjacent I-beams, and the ventilation slots coincide with the corresponding belt grooves.

[0008] The hollow support plate is coaxially fixedly installed with a shaft cylinder on one end face inside the hollow wheel;

[0009] The shaft, I-beam, and blades form an annular cavity corresponding to the automotive air conditioning compressor coil, and the diameter of the annular cavity is larger than the diameter of the automotive air conditioning compressor coil.

[0010] The hollow wheel has several V-shaped weight-reducing grooves evenly distributed on its circumference, and the V-shaped weight-reducing grooves are vertically intersecting with the belt grooves.

[0011] The I-beams are arranged alternately with each group of blades and are integrally fixedly connected with the hollow wheel and the hollow support plate.

[0012] The two sides of the I-beam and blades are flush with the two end faces of the hollow wheel disc.

[0013] Ventilation holes are provided through the surfaces of the I-beams and blades.

[0014] The thickness of the hollow support sheet is less than the thickness of the hollow wheel. One end face of the hollow support sheet is flush with one end face of the hollow wheel, and the other end face of the hollow support sheet is inside the hollow wheel.

[0015] The surface of the hollow support sheet is uniformly perforated with honeycomb weight-reducing holes.

[0016] The hollow support plate has a cover cavity coaxially formed on one end face that is flush with the hollow wheel.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] The overall design of this utility model allows for better and faster airflow between the coil assembly and the pulley during use, through the blades, thereby cooling the coil assembly, preventing heat buildup, and achieving more efficient heat dissipation. Attached Figure Description

[0027] Example

[0028] Reference Figure 1-3 A pulley structure for an automotive air conditioning compressor includes a hollow pulley 1, a hollow support plate 5, and a shaft cylinder 6. The hollow pulley 1 is coaxially sleeved on the outside of the hollow support plate 5. Several I-beams 3 and several sets of blades 4 are arranged between the inner circumferential surface of the hollow pulley 1 and the outer circumferential surface of the hollow support plate 5. This structure not only has a good ventilation and heat dissipation effect, but also reduces the overall weight while ensuring the overall strength.

[0029] In this case, the structure between the hollow wheel 1, the I-beam block 3, the blade 4, the hollow support plate 5 and the shaft cylinder 6 can be directly machined by a CNC machining center to form an integrated structure;

[0030] Specifically, the outer circumferential surface of the hollow wheel 1 is provided with a belt groove 2 so as to connect the belt through the belt groove 2 and ensure the stability and smoothness of the belt during operation.

[0031] Specifically, several sets of ventilation slots 8 are evenly distributed throughout the circumference of the hollow wheel 1. Each set of ventilation slots 8 is located between two adjacent I-beams 3. The ventilation slots 8 coincide with the corresponding belt grooves 2. By setting the ventilation slots 8, more air can enter the ring cavity through the ventilation slots, or in other words, the heat generated by the coil can be discharged in large quantities through the ventilation slots.

[0032] Specifically, a shaft cylinder 6 is coaxially fixedly installed on one end face of the hollow support plate 5 inside the hollow wheel 1 so that a bearing can be installed in the shaft cylinder 6;

[0033] Specifically, the shaft cylinder 6 forms an annular cavity corresponding to the automotive air conditioning compressor coil between the I-beam block 3 and the blade 4. The diameter of the annular cavity is larger than the diameter of the automotive air conditioning compressor coil. By setting the annular cavity, the pulley structure of the automotive air conditioning compressor can be sleeved on the outside of the compressor coil, and the I-beam block 3 and the blade 4 are prevented from contacting the coil, thereby preventing friction on the coil during rotation.

[0034] Specifically, the hollow wheel 1 has several V-shaped weight-reducing grooves 9 evenly distributed on its circumference. The V-shaped weight-reducing grooves 9 are vertically intersecting with the belt grooves 2. This structure can better reduce the overall weight, which can further reduce the overall weight of the vehicle when used in new energy vehicles, thereby improving the driving range.

[0035] Specifically, the I-beam 3 and each set of blades 4 are arranged alternately, and are integrally fixedly connected with the hollow wheel disk 1 and the hollow support plate 5;

[0036] Specifically, the two sides of the I-beam 3 and the blade 4 are flush with the two end faces of the hollow wheel 1.

[0037] Specifically, ventilation holes 10 are provided through the surfaces of the I-beam 3 and the blade 4 to allow for better air circulation and reduce the overall weight.

[0038] Specifically, the thickness of the hollow support piece 5 is less than the thickness of the hollow wheel 1, one end face of the hollow support piece 5 is flush with one end face of the hollow wheel 1, and the other end face of the hollow support piece 5 is inside the hollow wheel 1.

[0039] Specifically, the surface of the hollow support sheet 5 is uniformly perforated with honeycomb weight-reducing holes 11 to allow for better air circulation and reduce the overall weight.

[0040] Specifically, a cover cavity 7 is coaxially formed on one end face of the hollow support piece 5 that is flush with the hollow wheel 1.

[0041] It should be noted that the hollow pulley 1, hollow support plate 5 and shaft cylinder 6 adopt existing technologies, such as aluminum alloy (e.g., 7075 aviation aluminum alloy, 6061-T6), titanium alloy or high-performance engineering plastics (e.g., PEEK, low-temperature modified PA66), etc. These materials significantly reduce the weight of the pulley while meeting the strength requirements, thereby improving the responsiveness and energy efficiency of the transmission system.

[0042] 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.
