[0028] Referring to Figure 1 and Figure 2 The present application provides a damping device 100, which comprises an integrated main body 10 and a damping bushing 20, wherein the integrated main body 10 is used for mounting on the vehicle frame and carrying the compressor; the damping bushing 20 is located at the position where the vehicle frame and the integrated main body 10 are connected, and at the position where the compressor and the integrated main body 10 are connected. Specifically, the design of the integrated main body 10 facilitates production and use, and is compatible with the vehicle frame and the compressor, facilitating fixed connection with the vehicle frame and facilitating carrying of the compressor. The design of the damping bushing 20 can reduce the vibration amplitude of the compressor, and even completely block the vibration of the compressor. In use, the damping device 100 is fixed on the vehicle frame, and then the compressor is placed on the damping device 100, which is convenient to use.

[0029] Specifically, the damping bushing 20 in the damping device 100 plays a key role in improving damping effect, protecting components and optimizing equipment performance. Specifically, the damping bushing 20 is usually made of elastic materials such as rubber, polyurethane, etc. These materials have good elasticity and damping properties. When the compressor works and vibrates, the damping bushing 20 can absorb and disperse vibration energy, reducing the transmission of vibration from the damping device 100 to the vehicle frame, and reducing the vibration intensity felt by the people in the vehicle. At the same time, the damping bushing 20 can reduce the influence of resonance. When the vehicle is running, the damping bushing 20 can change the transmission path and frequency of vibration, effectively avoiding the occurrence of resonance. In addition, the damping bushing 20 has a protective effect, which can reduce the wear of the integrated main body 10. The damping bushing 20 acts as an isolation layer between the integrated main body 10 and other components, avoiding direct contact and friction between components. The damping bushing 20 can prevent the integrated main body 10 and the connecting components from being damaged due to long-term vibration and friction, prolonging the overall service life of the damping device 100. In addition, the damping bushing 20 can be used for adjustment and positioning, which is conducive to accurate position adjustment. The bushing can be used to fine-tune the position and angle between the integrated main body 10 and other components, ensuring the installation accuracy between components. The damping bushing 20 can also keep the components aligned. During vehicle operation, the damping bushing 20 can maintain the correct alignment relationship between the integrated main body 10 and the connecting components. Even under the action of vibration and external force, the damping bushing 20 can ensure that the components will not be misaligned, ensuring the normal operation of the equipment. The damping bushing 20 can also play the role of sound insulation and noise reduction, absorbing noise energy. In addition to buffering vibration, the bushing can also absorb and attenuate noise generated by vibration. The elastic damping bushing 20 can convert the mechanical energy of vibration into heat energy, thereby reducing the generation and propagation of noise, reducing the noise level in the vehicle and improving the quietness in the vehicle.

[0030] Please continue to refer to Figure 1The integral body part 10 comprises a first mounting hole 11 located at four corners of the integral body part 10, and a damping bushing 20 is placed in the first mounting hole 11. Specifically, the first mounting hole 11 is designed to facilitate the mounting of the integral body part 10 to the frame, and when the first mounting hole 11 is located at the four corners of the integral body part 10, the damping support and the frame have good fixing effect. At the same time, the damping bushing 20 is placed in the first mounting hole 11, which can avoid the transmission of the vibration of the compressor to the frame by the integral body part 10.

[0031] Please continue to refer to Figure 1 The integral body part 10 further comprises a second mounting hole 12 located at the front end of the integral body part 10 and penetrating the integral body part 10 in the direction in which the compressor and the damping device 100 are placed, and used for connecting with the front mounting point of the compressor. Specifically, the second mounting hole 12 in the integral body part 10 is connected with the front mounting point of the compressor, and the second mounting hole 12 penetrates the integral body part 10 in the direction in which the compressor and the damping device 100 are stacked, i.e. in the first direction X, which facilitates the connection between the damping device 100 and the front mounting point of the compressor.

[0032] Please continue to refer to Figure 1 And Figure 2 The integral body part 10 further comprises an extension part 13, one end of the extension part 13 is fixedly connected with the second mounting hole 12, and the other end of the extension part 13 is fixedly connected with the front mounting point of the compressor. Specifically, the extension part 13 is arranged to facilitate the adjustment of the distance between the front mounting point of the compressor and the integral body part 10, and to facilitate the stable connection between the compressor and the second mounting hole 12.

[0033] Please continue to refer to Figure 1 And Figure 2 The integral body part 10 further comprises two third mounting holes 14 arranged opposite to each other in a direction perpendicular to the direction in which the compressor and the damping device 100 are placed, and fixedly connected with the bottom mounting point of the compressor. Specifically, the third mounting holes 14 are arranged opposite to each other in the direction perpendicular to the direction in which the compressor and the damping device 100 are placed, i.e. in the second direction Y, and the second direction Y is perpendicular to the first direction X. The third mounting holes 14 are designed to facilitate the cooperation with the bottom mounting point of the compressor, and the damping bushing 20 is placed in the third mounting holes 14, which further plays a role in improving the connection accuracy.

[0034] Please continue to refer to Figure 1The damping bushing 20 is provided with a threaded hole (not shown in the figure) penetrating through. Specifically, the threaded hole is designed to facilitate the passage of the fastening member, thereby achieving position fixation. The damping bushing 20 is placed in the first mounting hole 11, the second mounting hole 12, and the third mounting hole 14, and position fixation between the compressor and the damping device 100, and between the damping device 100 and the vehicle frame is achieved through the threaded hole in the damping bushing 20.

[0035] Please refer to Figure 2 , Figure 3 and Figure 4 , the damping device 100 further comprises a counterweight 30, which is symmetrically arranged on the integrated main body 10. The counterweight 30 comprises a bottom plate 31 and two side plates 32. The bottom plate 31 is located below the integrated main body 10, and the side plates 32 are located on both sides of the integrated main body 10. The integrated main body 10 and the counterweight 30 are fixed by installing screws through the integrated main body 10 and the side plates 32. Specifically, the integrated main body 10 is provided with a fourth through hole 15 penetrating through the sidewall of the integrated main body 10, and the mounting hole on the side plate 32 of the counterweight 30 is aligned with the fourth through hole 15, thereby achieving fixed connection of the counterweight 30 and the integrated main body 10. By adding a certain mass to the integrated main body 10, the vibration amplitude of the compressor can be suppressed, further reducing the vibration energy, and the problem of booming in the vehicle caused by resonance between the integrated main body 10 and the compressor can be solved. The design of the counterweight 30 can directly suppress the vibration amplitude of the compressor support, and quickly solve the existing problem of booming resonance in the vehicle.

[0036] In an embodiment, by using the damping device 100 in the present application, the required counterweight mass can be selected as needed, the counterweight 30 is installed on the integrated main body 10, directly suppressing the vibration of the compressor support, quickly solving the booming problem caused by resonance between the compressor in the vehicle and the original support, obtaining a better driving experience while saving layout space.

[0037] Please continue to refer to Figure 3 , the counterweight 30 further comprises a rubber pad 33 located on the surface of the counterweight 30 in contact with the integrated main body 10. The rubber pad 33 can protect the contact surface of the integrated main body 10 and the counterweight 30, avoid wear and tear, and prolong the service life of the damping device 100.

[0038] Please refer to Figure 4 , the surface of the integrated main body 10 close to the compressor has a groove 16; specifically, the design of the groove 16 can enhance the surface strength, avoid cracking, and prolong the service life of the integrated main body 10.

[0039] Please refer to Figure 5The surface of the integrated main body part 10 away from the compressor has a reinforcing rib 17. On the one hand, it can reduce weight and achieve lightweight, and on the other hand, it can increase structural strength and improve stability. Specifically, on the one hand, the design of the reinforcing rib 17 can improve the load-bearing capacity of the integrated main body part 10: when subjected to external force, the reinforcing rib 17 can effectively disperse stress and avoid local stress concentration, so that the integrated main body part 10 can withstand greater pressure without damage. On the other hand, the design of the reinforcing rib 17 can improve the load-bearing capacity of the integrated main body part 10, resist deformation, maintain the shape and size stability of the integrated main body part 10, and ensure the normal operation of the shock-absorbing device 100.
