For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Reference below Figure 1-Figure 7 A compressor fixing structure 100 according to an embodiment of the present invention is described.

[0044] like Figure 1 and Figure 2 As shown, the compressor fixing structure 100 according to the embodiment of the utility model includes a first bracket 1, a first vibration damping member 2, a second bracket 3, a second vibration damping member 4 and a third vibration damping member 5.

[0045] Specifically, Figure 1 and Figure 2 As shown, combined Figure 3The first bracket 1 is used to fix the compressor 7. The first vibration damper 2 is arranged between the first bracket 1 and the compressor 7, and is used to reduce the vibration transmission between the compressor 7 and the first bracket 1; the second bracket 3 is connected to the first bracket 1 and is located on the side of the first bracket 1 away from the compressor 7; the second vibration damper 4 is arranged between the first bracket 1 and the second bracket 3, and is used to reduce the vibration transmission between the first bracket 1 and the second bracket 3; the second bracket 3 is connected to the fixing member 8, and the third vibration damper 5 is arranged on the second bracket 3 and is located between the fixing member 8 and the second bracket 3, and is used to reduce the vibration transmission between the second bracket 3 and the fixing member 8 on which the compressor 7 is installed.

[0046] It is understandable that the first bracket 1 can be connected to the compressor 7 and the second bracket 3 respectively by fasteners such as bolts and nuts, and the compressor 7 is installed on the fixing member 8 through the first bracket 1 and the second bracket 3, which is convenient for the operator to assemble. In the specific assembly process, the operator can first connect the first bracket 1 and the second bracket 3 as a whole, then install the first bracket 1 and the second bracket 3 on the fixing member 8, and finally fix the compressor 7 to the first bracket 1 by fasteners, thereby completing the assembly of the compressor 7 and the fixing member 8.

[0047] The first vibration damper 2, the second vibration damper 4 and the third vibration damper 5 can be rubber parts, which can effectively absorb and disperse vibration energy. The first vibration damper 2 is arranged between the first bracket 1 and the compressor 7, which can reduce the vibration transmitted from the compressor 7 to the first bracket 1. The second vibration damper 4 is arranged between the first bracket 1 and the second bracket 3, which can prevent the vibration transmitted from the compressor 7 to the first bracket 1 from being directly transmitted to the second bracket 3, providing an additional vibration damping effect. The third vibration damper 5 is arranged between the second bracket 3 and the fixing member 8, which can prevent the vibration transmitted from the first bracket 1 to the second bracket 3 from continuing to be transmitted to the fixing member 8, further enhancing the vibration damping effect. When the compressor 7 is applied to a vehicle, by setting the above-mentioned compressor fixing structure 100, the vibration of the compressor 7 can be prevented from being directly transmitted to the fixing member 8 of the vehicle, thereby preventing the steering wheel or floor resonance in the vehicle caused by excessive vibration of the compressor 7.

[0048] By setting the first vibration damper 2, the second vibration damper 4 and the third vibration damper 5, a multi-stage vibration damping structure can be formed, and the structure is simple and easy to implement. The first vibration damper 2 directly acts between the compressor 7 and the first bracket 1, and can form the first stage of vibration damping, effectively reducing the vibration impact of the compressor 7 on the first bracket 1 when working. The second vibration damper 4 can form the second stage of vibration damping, further reducing the vibration transmission between the first bracket 1 and the second bracket 3, and the third vibration damper 5 can form the third stage of vibration damping, further improving the vibration damping effect between the second bracket 3 and the fixing member 8. In this way, it can be ensured that the transmission of the vibration energy of the compressor 7 is weakened to the greatest extent, and the vibration-proof effect of the compressor fixing structure 100 is enhanced.

[0049] In addition, the three-stage vibration damping structure formed by the first vibration damper 2, the second vibration damper 4 and the third vibration damper 5 can also effectively reduce the noise generated by vibration, provide a quieter condition for the application environment of the compressor 7, and thus improve the NVH comfort of the user.

[0050] According to the compressor fixing structure 100 of the embodiment of the utility model, by arranging a first vibration damping member 2 for reducing the vibration transmission between the compressor 7 and the first bracket 1 on the first bracket 1 for fixing the compressor 7, and arranging a second vibration damping member 4 for reducing the vibration transmission between the first bracket 1 and the second bracket 3 and a third vibration damping member 5 for reducing the vibration transmission between the second bracket 3 and the fixing member 8, a multi-stage vibration damping structure can be formed, and the structure is simple and easy to implement, which can enhance the vibration-proof effect of the compressor fixing structure 100 and reduce the noise level, thereby improving the NVH comfort of the user.

[0051] In some embodiments of the present invention, Figure 2 , Figure 3 and Figure 4 As shown, the first vibration damper 2 is interference fit with the compressor 7 and the first bracket 1, and the first vibration damper 2 can be a rubber support pad with good elasticity. Among them, the distance between the contact surface between the first bracket 1 and the first vibration damper 2 and the contact surface between the compressor 7 and the first vibration damper 2 is a, and the thickness of the first vibration damper 2 is greater than a. When the compressor 7 is assembled with the first bracket 1, the first vibration damper 2 is compressed by force and is tightly clamped between the compressor 7 and the first bracket 1, so that the first vibration damper 2 is tightly fitted with the compressor 7 and the first bracket 1 respectively, which can disperse and weaken the vibration transmission between the first bracket 1 and the compressor 7, thereby ensuring the vibration reduction effect between the compressor 7 and the first bracket 1.

[0052] In some embodiments of the present invention, Figure 2 , Figure 3 and Figure 4 As shown, the first vibration damper 2 and the first bracket 1 are an integral part. The first vibration damper 2 can be combined with the first bracket 1 into one piece through a vulcanization process. The structure is simple, which can simplify the assembly process and reduce the number of parts required for assembly, thereby reducing the difficulty of assembly and improving the assembly efficiency. Workers do not need to spend extra time to install the first vibration damper 2 separately, thereby reducing the assembly time and further reducing the assembly cost. At the same time, setting the first vibration damper 2 and the first bracket 1 as an integral part can avoid the problem of displacement or falling off of the first vibration damper 2 during the operation of the compressor 7, improve the structural stability of the compressor fixing structure 100, ensure the anti-vibration effect on the compressor 7, and reduce the later maintenance time and cost.

[0053] In some embodiments of the present invention, Figure 1 , Figure 3 and Figure 4 As shown, the first bracket 1 and the compressor 7 are connected by a first fastener, and the first bracket 1 is provided with a first mounting hole 11 and a second mounting hole 12 for the first fastener to pass through on opposite sides, and the compressor 7 is provided with a third mounting hole for the first fastener to pass through, and the third mounting hole is located between the first mounting hole 11 and the second mounting hole 12.

[0054] It should be noted that, Figure 3 In the example shown, the compressor fixing structure 100 may also include a projection welding nut 6, which is located on the side of the second mounting hole 12 away from the first mounting hole 11 and is welded to the first bracket 1. The end of the compressor 7 close to the first bracket 1 may be provided with a sleeve 71, and the third mounting hole passes through the sleeve 71 in the extension direction of the first fastener. By providing the first mounting hole 11, the second mounting hole 12 and the third mounting hole, it is convenient for the operator to pass the first fastener through the first mounting hole 11 of the first bracket 1, the third mounting hole of the compressor 7 and the second mounting hole 12 of the first bracket 1 in sequence, and then fix the first fastener to the projection welding nut 6 to complete the assembly of the compressor 7, which can ensure the connection stability between the compressor 7 and the first bracket 1 and facilitate the operation of the operator.

[0055] Furthermore, if Figure 2 In the example shown, a nut 9 is provided at one end of the first fastener facing away from the projection welding nut 6 . The nut 9 is located on the side of the first mounting hole 11 facing away from the second mounting hole 12 , which can enhance the connection stability between the first bracket 1 and the compressor 7 .

[0056] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, the first bracket 1 includes a first plate body 13, a second plate body 14 and a third plate body 15, one end of the second plate body 14 and one end of the third plate body 15 are respectively connected to the two opposite ends of the first plate body 13, one end of the second plate body 14 away from the first plate body 13 and one end of the third plate body 15 away from the first plate body 13 respectively extend toward the same side of the thickness direction of the first plate body 13, the first mounting hole 11 is provided on one of the second plate body 14 and the third plate body 15, and the second mounting hole 12 is provided on the other of the second plate body 14 and the third plate body 15.

[0057] It is understandable that by providing the above-mentioned first plate body 13, second plate body 14 and third plate body 15, it is convenient to provide the first mounting hole 11 and the second mounting hole 12 on opposite sides of the first bracket 1, so that the first fastener can pass through the first mounting hole 11, the third mounting hole and the second mounting hole 12 in sequence to complete the installation of the compressor 7. The first bracket 1 has a simple structure, a reasonable arrangement and is easy to implement, which is convenient for the arrangement, connection and installation of the compressor 7.

[0058] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, there are multiple first fasteners, the first mounting holes 11 and the second mounting holes 12 are both corresponding multiples, and the projection welding nut 6, the nut 9 and the third mounting hole of the compressor 7 are also multiples corresponding to the multiple first fasteners. The operator can pass the multiple first fasteners through the corresponding first mounting holes 11, the third mounting holes and the second mounting holes 12 in sequence, and then fix the first fasteners to the projection welding nut 6 and the nut 9 respectively to complete the assembly of the compressor 7, so that the compressor 7 is connected to the first bracket 1 at multiple locations, which can enhance the connection stability between the first bracket 1 and the compressor 7.

[0059] At the same time, there are multiple first vibration dampers 2, and a first vibration damper 2 is provided between any two adjacent first fasteners. Multiple first vibration dampers 2 are sandwiched between the compressor 7 and the first bracket 1, so that the first vibration dampers 2 absorb and disperse the vibration energy of the compressor 7 at multiple locations, which can further improve the weakening effect of the first vibration damper 2 on the vibration transmission between the compressor 7 and the first bracket 1, thereby enhancing the vibration-proof effect of the compressor fixing structure 100 and reducing the noise level, thereby improving the NVH comfort of the user.

[0060] In some embodiments of the present invention, Figure 3 As shown, the first vibration damper 2 extends along the length direction of the first fastener. The extension direction of the first vibration damper 2 is consistent with the installation direction of the first fastener, and the structure is reasonably arranged, which is convenient for the installation of the first fastener. In addition, the first vibration damper 2 can make the force on the compressor 7 and the first bracket 1 in the length direction of the first fastener more uniform, and can disperse the vibration transmission between the compressor 7 and the first bracket 1 in the length direction of the first fastener, thereby enhancing the vibration reduction effect between the compressor 7 and the first bracket 1, and then enhancing the vibration-proof effect of the compressor fixing structure 100 and reducing the noise level, thereby improving the NVH comfort of the user.

[0061] In some embodiments of the present invention, Figure 1 , Figure 4 and Figure 5As shown, the first bracket 1 and the second bracket 3 are connected by a second fastener, and the second vibration damping member 4 is sleeved on the second fastener and is interference fit with the first bracket 1 and the second bracket 3 .

[0062] The first bracket 1 may be provided with a first fixing hole 18, and the second bracket 3 may be provided with a second fixing hole 32 corresponding to the first fixing hole 18. The second vibration damper 4 is sleeved on the second fastener. In the specific assembly process, the operator can pass the two ends of the second fastener in the length direction through the first fixing hole 18 and the second fixing hole 32 respectively, so that the second vibration damper 4 is between the first bracket 1 and the second bracket 3. Then the second fastener is fixedly connected with the first nut 41 and the second nut 42 respectively, wherein the first nut 41 is located on the side of the first bracket 1 away from the second bracket 3, and the second nut 42 is located on the side of the second bracket 3 away from the first bracket 1. In this way, the second vibration damper 4 is tightly clamped between the first bracket 1 and the second bracket 3, so that the vibration reduction effect between the first bracket 1 and the second bracket 3 can be ensured.

[0063] In some embodiments of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the second fasteners are multiple and spaced apart, and the second vibration dampers 4 are multiple and correspond to the multiple second fasteners. The first fixing hole 18, the second fixing hole 32, the first nut 41 and the second nut 42 are also multiple and correspond to the second fasteners, which can form multiple connections between the first bracket 1 and the second bracket 3, so that the force of the first bracket 1 and the second bracket 3 is more uniform, thereby enhancing the connection stability between the first bracket 1 and the second bracket 3. At the same time, there are multiple second vibration dampers 4, and multiple second vibration dampers 4 are tightly clamped between the first bracket 1 and the second bracket 3, so that the second vibration dampers 4 can absorb and disperse vibration energy at multiple locations, thereby improving the weakening effect of the second vibration dampers 4 on the vibration transmission between the first bracket 1 and the second bracket 3, thereby enhancing the vibration-proof effect of the compressor fixing structure 100 and reducing the noise level, thereby improving the NVH comfort of the user.

[0064] In some embodiments of the present invention, Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the second bracket 3 is provided with a pin 31, the fixing member 8 is provided with a fixing hole 81, the pin 31 is at least partially located in the fixing hole 81, and the third vibration damper 5 is at least partially located in the fixing hole 81 and sleeved outside the pin 31. The third vibration damper 5 can be provided with a pin hole 53, the pin hole 53 extends along the axial direction of the third vibration damper 5, the pin 31 is provided on the side of the second bracket 3 away from the compressor 7 and is matched and connected with the pin hole 53, and at least part of the outer peripheral wall of the third vibration damper 5 is matched and connected with the inner peripheral wall of the fixing hole 81. By providing the pin 31, the fixing hole 81 and the third vibration damper 5, it is convenient to connect the second bracket 3 and the fixing member 8, which is convenient for assembly, and at the same time, the vibration transmission between the second bracket 3 and the fixing member 8 can be weakened and the noise level can be reduced, thereby improving the NVH comfort of the user.

[0065] Among them, the second bracket 3 is provided with multiple pins 31, and the third vibration damping member 5 and the fixing holes 81 are multiple corresponding to the pins 31, so that the second bracket 3 is connected to the fixing member 8 at multiple locations, which can further enhance the connection stability between the second bracket 3 and the fixing member 8, and at the same time can enhance the weakening effect of vibration transmission between the second bracket 3 and the fixing member 8.

[0066] In some embodiments of the present invention, Figure 4 , Figure 5 and Figure 6 As shown, the third vibration damper 5 is interference fit with the pin 31, and the outer diameter of the pin 31 is slightly larger than the inner diameter of the pin hole 53 on the third vibration damper 5. By applying a certain pressure, the pin 31 is inserted into the pin hole 53 and fits tightly, which is simple to assemble and can enhance the connection stability between the pin 31 and the third vibration damper 5.

[0067] Furthermore, the third vibration damper 5 is interference fit with the fixing hole 81, and the outer diameter of the third vibration damper 5 is slightly larger than the inner diameter of the fixing hole 81. By applying a certain pressure, the third vibration damper 5 is extended into the fixing hole 81 and fits tightly, which is simple to assemble and can enhance the stability of the connection between the third vibration damper 5 and the fixing member 8.

[0068] In some embodiments of the present invention, Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, along the axial direction of the third vibration damper 5, the third vibration damper 5 includes a connected third section 51 and a fourth section 52, the outer diameter of the third section 51 is greater than the outer diameter of the fourth section 52 and greater than the inner diameter of the fixing hole 81, the third section 51 is located outside the fixing hole 81 and between the second bracket 3 and the fixing member 8, and at least part of the fourth section 52 is located in the fixing hole 81 and cooperates with the fixing hole 81. The third section 51 is sleeved on the pin 31 and located between the second bracket 3 and the fixing member 8, which can avoid direct rigid contact between the second bracket 3 and the fixing member 8, thereby reducing the vibration transmission between the second bracket 3 and the fixing member 8 and ensuring the vibration-proof effect of the third vibration damper 5. At least part of the fourth section 52 is located in the fixing hole 81 and has an interference fit with the fixing hole 81. By setting the fourth section 52, it is convenient to assemble the third vibration damper 5 with the fixing member 8, and at the same time, the vibration-proof effect between the second bracket 3 and the fixing member 8 can be ensured.

[0069] In some embodiments of the present invention, Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, along the axial direction of the third vibration damper 5, the fourth section 52 includes a matching section 521 and an entry section 522, the matching section 521 is arranged close to the third section 51 relative to the entry section 522, the outer diameter of the matching section 521 is larger than the outer diameter of the entry section 522, and the matching section 521 is interference fit with the fixing hole 81. The outer diameter of the matching section 521 is slightly larger than the inner diameter of the fixing hole 81, so that the matching section 521 can achieve an interference fit with the fixing hole 81, thereby ensuring the connection stability between the fourth section 52 and the fixing member 8. Furthermore, the outer diameter of the entry section 522 gradually decreases in the direction away from the mating section 521, and the outer diameter of the end of the entry section 522 away from the mating section 521 can be slightly smaller than the inner diameter of the fixing hole 81, thereby facilitating the insertion of the entry section 522 into the fixing hole 81 and guiding the mating section 521 into the fixing hole 81, which can save the operator the force required to insert the fourth section 52 into the fixing hole 81, reduce the difficulty of assembling the third vibration damper 5 and the fixing member 8, and thus improve the assembly efficiency.

[0070] In this application, if Figure 6 As shown, the third vibration damping member 5 is a rubber member with good elasticity, which can effectively absorb and disperse vibration energy, thereby weakening the vibration transmission between the second bracket 3 and the fixing member 8, and at the same time can also reduce the propagation of sound, thereby improving the NVH comfort of the user.

[0071] In this application, if Figure 3 , Figure 4 and Figure 5As shown, the second bracket 3 has a protrusion 34 on the side facing the first bracket 1, and the protrusion 34 is formed by a part of the second bracket 3 protruding toward the first bracket 1. A groove 33 is provided at a position corresponding to the protrusion 34 on the side of the second bracket 3 away from the first bracket 1. The protrusion 34 and the groove 33 extend from one end of the second bracket 3 to the other end in the width direction of the second bracket 3. The extension direction of the protrusion 34 and the groove 33 can be the same as the arrangement direction of the second plate body 14 and the third plate body 15. The protrusion 34 can enhance the structural strength of the second bracket 3, and the groove 33 can avoid other structures and components, so that the assembly between the compressor fixing structure 100 and the fixing member 8 is more compact, thereby saving layout space.

[0072] Furthermore, a reinforcing rib 331 is provided at the connection between the bottom wall and the side wall of the groove 33, and a plurality of reinforcing ribs 331 may be arranged at intervals, so as to increase the structural strength of the second bracket 3 and improve the bearing capacity of the second bracket 3, thereby reducing the possibility of deformation of the second bracket 3, and at the same time enhancing the structural stability of the second bracket 3 and extending its service life.

[0073] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, at least one of the first bracket 1 and the second bracket 3 has a weight-reducing hole 16, and the weight-reducing hole 16 can penetrate the first bracket 1 or the second bracket 3 in the thickness direction of the first bracket 1 or the second bracket 3. Under the premise of not affecting the performance of the first bracket 1 and the second bracket 3, the weight of the first bracket 1 and the second bracket 3 can be reduced, and the lightweight design of the first bracket 1 and the second bracket 3 can be realized, thereby reducing the load of the fixing member 8, which is conducive to ensuring the connection stability between the second bracket 3 and the fixing member 8. Of course, under the premise of not affecting the performance of the first bracket 1 and the second bracket 3, there can be multiple weight-reducing holes 16 on the first bracket 1 or the second bracket 3, and the present application does not specifically limit the position, number and shape of the weight-reducing holes 16.

[0074] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, at least one of the first bracket 1 and the second bracket 3 has an identification hole 17 for indicating the installation direction of the compressor 7. The identification hole 17 may be a triangular hole provided on the first bracket 1, which may indicate the installation direction of the compressor 7 to the operator. For example, it may be noted in the installation manual that in the extension direction of the bolt, the end of the compressor 7 provided with the wiring harness assembly is provided in the direction of the angle provided by the identification hole 17, so as to prevent the operator from installing the compressor 7 upside down and affecting the subsequent assembly and use. Of course, the identification hole 17 may also be provided on the second bracket 3, or the identification hole 17 may be provided on both the first bracket 1 and the second bracket 3.

[0075] A vehicle according to an embodiment of the present invention is described below.

[0076] The vehicle according to the embodiment of the present utility model comprises a fixing member 8 and the above-mentioned compressor fixing structure 100 .

[0077] Specifically, Figure 1 and Figure 2 As shown, combined Figure 2 and Figure 3 The compressor fixing structure 100 includes a first bracket 1, a first vibration damper 2, a second bracket 3, a second vibration damper 4 and a third vibration damper 5. The first bracket 1 is used to fix the compressor 7. The first vibration damper 2 is arranged between the first bracket 1 and the compressor 7, and is used to reduce the vibration transmission between the compressor 7 and the first bracket 1; the second bracket 3 is connected to the first bracket 1 and is located on the side of the first bracket 1 away from the compressor 7; the second vibration damper 4 is arranged between the first bracket 1 and the second bracket 3, and is used to reduce the vibration transmission between the first bracket 1 and the second bracket 3; the second bracket 3 is connected to the fixing member 8, and the third vibration damper 5 is arranged on the second bracket 3 and is located between the fixing member 8 and the second bracket 3, and is used to reduce the vibration transmission between the second bracket 3 and the fixing member 8 on which the compressor 7 is installed.

[0078] It is understandable that the first bracket 1 can be connected to the compressor 7 and the second bracket 3 respectively by fasteners such as bolts and nuts, and the compressor 7 is installed on the fixing member 8 through the first bracket 1 and the second bracket 3, which is convenient for the operator to assemble. In the specific assembly process, the operator can first connect the first bracket 1 and the second bracket 3 as a whole, then install the first bracket 1 and the second bracket 3 on the fixing member 8, and finally fix the compressor 7 to the first bracket 1 by fasteners, thereby completing the assembly of the compressor 7 and the fixing member 8.

[0079] The first vibration damper 2, the second vibration damper 4 and the third vibration damper 5 can be rubber parts, which can effectively absorb and disperse vibration energy. The first vibration damper 2 is arranged between the first bracket 1 and the compressor 7, which can reduce the vibration transmitted from the compressor 7 to the first bracket 1. The second vibration damper 4 is arranged between the first bracket 1 and the second bracket 3, which can prevent the vibration transmitted from the compressor 7 to the first bracket 1 from being directly transmitted to the second bracket 3, providing an additional vibration damping effect. The third vibration damper 5 is arranged between the second bracket 3 and the fixing member 8, which can prevent the vibration transmitted from the first bracket 1 to the second bracket 3 from continuing to be transmitted to the fixing member 8, further enhancing the vibration damping effect. When the compressor 7 is applied to a vehicle, by setting the above-mentioned compressor fixing structure 100, the vibration of the compressor 7 can be prevented from being directly transmitted to the fixing member 8 of the vehicle, thereby preventing the steering wheel or floor resonance in the vehicle caused by excessive vibration of the compressor 7.

[0080] By setting the first vibration damper 2, the second vibration damper 4 and the third vibration damper 5, a multi-stage vibration damping structure can be formed, and the structure is simple and easy to implement. The first vibration damper 2 directly acts between the compressor 7 and the first bracket 1, and can form the first stage of vibration damping, effectively reducing the vibration impact of the compressor 7 on the first bracket 1 when working. The second vibration damper 4 can form the second stage of vibration damping, further reducing the vibration transmission between the first bracket 1 and the second bracket 3, and the third vibration damper 5 can form the third stage of vibration damping, further improving the vibration damping effect between the second bracket 3 and the fixing member 8. In this way, it can be ensured that the transmission of the vibration energy of the compressor 7 is weakened to the greatest extent, and the vibration-proof effect of the compressor fixing structure 100 is enhanced.

[0081] In addition, the three-stage vibration damping structure formed by the first vibration damper 2, the second vibration damper 4 and the third vibration damper 5 can also effectively reduce the noise generated by vibration, provide a quieter condition for the application environment of the compressor 7, and thus improve the NVH comfort of the user.

[0082] According to the vehicle of the embodiment of the utility model, by arranging a first vibration damping member 2 for reducing the vibration transmission between the compressor 7 and the first bracket 1 on the first bracket 1 for fixing the compressor 7, and arranging a second vibration damping member 4 for reducing the vibration transmission between the first bracket 1 and the second bracket 3 and a third vibration damping member 5 for reducing the vibration transmission between the second bracket 3 and the fixing member 8, a multi-stage vibration damping structure can be formed, and the structure is simple and easy to implement, which can enhance the vibration-proof effect of the compressor fixing structure 100 and reduce the noise level, thereby improving the NVH comfort of the user.

[0083] In some embodiments of the utility model, the fixing part 8 is formed as a subframe, an engine or an electric drive integrated system assembly, and the above-mentioned compressor 7 and the compressor fixing structure 100 can be fixed to the subframe, the engine or the electric drive integrated system assembly, which can reduce the vibration transmission between the compressor 7 and the subframe, the engine or the electric drive integrated system assembly and improve the user's NVH comfort.
