[0002] Vehicle air suspension systems are primarily used to adjust vehicle ground clearance by regulating air pressure. A vehicle air suspension system includes components such as air springs, an air supply unit, and air springs. The air supply unit typically includes an air compressor, solenoid valves, structural supports, various levels of damping mounts, intake and exhaust pipes, and electrical connectors; it is usually responsible for generating, storing, and regulating compressed air, and delivering the compressed air to the air springs to control the inflation and deflation of the air springs, thereby adjusting the suspension stiffness and vehicle height.
[0003] In existing technologies, air compressors are mostly piston-type brushed motor structures, which have relatively high overall operating noise. Therefore, air compressors are usually arranged in the acoustic package through vibration damping units. The acoustic package is then connected to the vehicle body through other vibration damping units and connecting brackets. However, the acoustic package structure is relatively complex, resulting in a large overall volume of the acoustic package structure, which further increases the volume of the connecting bracket structure. This leads to a large overall volume and weight of the air supply unit, which occupies a lot of vertical space under the vehicle and increases costs.
[0004] Therefore, it is necessary to provide a suspension assembly for an air supply unit. Utility Model Content

Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.
[0037] like Figure 1-4 As shown, this embodiment provides an air supply unit 100, which includes an air compressor 1, a suspension assembly 2 for suspending the air compressor 1, a distribution valve 3, an air pipe assembly 4, a motor wiring harness 5, a high-pressure charging pipe 6, and an auxiliary wiring harness 7 installed on the air compressor 1. The air compressor 1 is provided with a plurality of bolt holes 11 for connecting the suspension assembly 2.
[0038] like Figure 3 As shown, the suspension assembly 2 consists of a first support plate 21, a second support plate 22, a primary suspension 23, and bolts 24. The first support plate 21 and the second support plate 22 are connected by the primary suspension 23. The first support plate 21 has a mounting portion 210, which is recessed to form a mounting support surface 211. A through hole 214 is opened in the middle of the mounting support surface 211. In this embodiment, there are three sets of such mounting portions 210. The primary suspension 23 passes through the through hole 215 to connect the first support plate 21 and the second support plate 22. The second support plate 22 has three bolt through holes 221 and three mounting holes 222. The second support plate 22 is connected to the air compressor 1 by bolts 24, which pass through the bolt through holes 221 and bolt holes 11 and are fixedly installed on the air compressor 1. The first support plate 21 is also equipped with a connecting bracket 212 and several clips 213. The distribution valve 3 is mounted on the connecting bracket 212. One end of the high-pressure charging pipe 6 is inserted into the high-pressure quick connector of the air compressor 1, and the other end is inserted into the pressure supply port of the distribution valve 3. The air pipe assembly 4 includes an inlet pipe 41 and an exhaust pipe 42. The inlet pipe 41 is connected to the air inlet (not shown in the figure) of the air compressor 1, and the exhaust pipe 42 is connected to the exhaust port (not shown in the figure) of the air compressor 1. The first support plate 21 is fixed with clips 213. The motor harness 5 is connected to the motor interface (not shown in the figure) of the air compressor 1 and fixed with clips 213 on the first support plate 21. The auxiliary harness 7 is connected to the auxiliary interface (not shown in the figure) of the air compressor and fixed with clips 213 on the first support plate 21.
[0039] In this embodiment, as Figure 3 As shown, the first support plate 21 is also provided with a mounting surface 215, in which a mounting round hole 216 is provided. The bottom of the vehicle is also provided with a flat mounting hole for direct contact with the flat mounting hole on the bottom of the vehicle. The mounting round hole 216 and the flat mounting hole are connected by bolts to connect the air supply unit 100 to the bottom of the vehicle.
[0040] In this embodiment, as Figure 4-5As shown, the primary suspension 23 is an elastic connection device, including a screw 231, a rubber bushing 234 fitted onto the screw 231, and a rubber pad 232 and a spring 233 disposed between the screw 231 and the rubber bushing 234. The rubber pad 232 is disposed on the screw shank near the head of the screw 231, and one end of the spring 233 abuts against the rubber pad, while the other end is compressed in the mounting hole 222. In actual installation, the rubber pad 232 and the spring 233 are fitted onto the screw 231, and then the rubber bushing 234 is fitted on top. A portion of the screw 233 and the rubber bushing 234 are passed through the through hole 215, and the bottom of the screw 233 passes through the mounting hole 222 and is secured with a nut. The middle portion of the rubber bushing 234 is snapped onto the mounting support surface 211, connecting the first support plate 21 and the second support plate 22. After the first support plate 21 and the second support plate 22 are connected and assembled through the first-stage suspension 23, the air compressor 1 is fixed on the second support plate 22. Finally, the air compressor 1 and the suspension assembly 2 are directly assembled on the bottom of the vehicle to reduce the space occupied on the bottom of the vehicle.
[0041] In this embodiment, as Figure 3 As shown, both the first support plate 21 and the second support plate 22 are irregular quadrilaterals made of sheet metal, with a raised center section on each surface. This strengthens the structural strength of the first support plate 21 and the second support plate 22 and avoids the area where the air compressor 1 is installed. Simultaneously, without affecting the strength of the suspension assembly 2, grooves are provided on both sides of the raised surfaces of the first support plate 21 and the second support plate 22 to reduce their weight. This keeps the thickness of the first support plate 21 and the second support plate 22 to approximately 2mm to 4mm, achieving weight reduction and cost reduction.
[0042] The air supply unit 100 of this embodiment includes an air compressor 1, a suspension assembly 2, a distribution valve 3, an air pipe assembly 4, a motor wiring harness 5, a high-pressure inflation pipe 6, and an auxiliary wiring harness 7. The suspension assembly 2 includes a first support plate 21 and a second support plate 22. The first support plate 21 is directly connected to the bottom of the vehicle, and the second support plate 22 is connected to the air compressor 1. The air compressor 1 is connected to the second sheet metal support plate 52 by bolts 54. The first sheet metal support plate 51 and the second sheet metal support plate 52 are connected by several primary suspension mounts 53. This embodiment replaces the complex acoustic package and the connecting bracket of the suspension acoustic package in the existing air supply unit with the suspension assembly 100, directly connecting the air supply unit 100 to the vehicle body, greatly reducing the vertical space occupied at the bottom of the vehicle. Furthermore, the use of primary suspension mounts 23 in the suspension assembly 2 to connect the second support plate 22 and the air compressor 1 to the first support plate 21 reduces the overall volume and weight of the air supply unit 100, thus lowering the cost.
[0043] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
