In micro electric vehicles, due to the limited space for cabin layout, the compressor is generally fixed to the subframe, engine or electric drive integrated system assembly through a primary vibration damping bracket. The vibration-proof effect of the primary vibration damping structure is not good, resulting in poor NVH (Noise, Vibration, Harshness) comfort for users. In vehicles with larger layout space, the compressor of some models is fixed to the subframe, engine or electric drive integrated system assembly through a secondary vibration damping bracket, but the existing secondary vibration damping structure is complex and has many parts, resulting in low assembly efficiency and high assembly cost. Therefore, how to improve assembly efficiency and reduce costs while improving NVH comfort has become a problem. Utility Model Content

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

[0044] Reference below Figure 1-Figure 9 A compressor fixing structure 100 according to an embodiment of the present invention is described.

[0045] like Figure 1 and Figure 2 As shown, the compressor fixing structure 100 according to the embodiment of the utility model includes a bracket 1, a first vibration damping member 2 and a second vibration damping member 3.

[0046] Specifically, Figure 1 and Figure 2 As shown, combined Figure 3 and Figure 4 The bracket 1 is used to fix the compressor 7. The first vibration damper 2 is arranged on the bracket 1 and is an integral part with the bracket 1, and is used to reduce the vibration transmission between the compressor 7 and the bracket 1. The second vibration damper 3 is arranged on the bracket 1, and is used to reduce the vibration transmission between the bracket 1 and the fixing member 8 for mounting the compressor 7.

[0047] It is understandable that the compressor 7 and the bracket 1 can be connected by fasteners such as bolts 5 and nuts 4, and the compressor 7 is installed on the fixing member 8 through the bracket 1, which is convenient for the operator to assemble. The first vibration damper 2 and the second vibration damper 3 can be rubber parts, which can effectively absorb and disperse vibration energy. The first vibration damper 2 is arranged on the bracket 1 and connected to the compressor 7, which can reduce the vibration transmission between the compressor 7 and the bracket 1. The second vibration damper 3 is arranged between the bracket 1 and the fixing member 8, which can prevent the vibration transmitted from the compressor 7 to the bracket 1 from being directly transmitted to the fixing member 8, providing an additional vibration reduction effect. When the compressor 7 is applied to a vehicle, the compressor fixing structure 100 can prevent the steering wheel or floor in the vehicle from resonating due to excessive vibration of the compressor 7.

[0048] By providing the first vibration damping member 2 and the second vibration damping member 3, a two-stage vibration damping structure can be formed, and the structure is simple and easy to implement. The first vibration damping member 2 directly acts between the compressor 7 and the bracket 1 to form the first-stage vibration damping, effectively reducing the vibration impact of the compressor 7 on the bracket 1 when it is working. The second vibration damping member 3 can form the second-stage vibration damping, further reducing the vibration transmission between the bracket 1 and the fixing member 8, thereby ensuring that the transmission of the vibration energy of the compressor 7 is weakened to the greatest extent, and enhancing the vibration-proof effect of the compressor fixing structure 100.

[0049] In addition, the secondary vibration damping structure formed by the first vibration damping member 2 and the second vibration damping member 3 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] Among them, the first vibration damper 2 can be a rubber pad, and the first vibration damper 2 is combined with the bracket 1 into one body 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 thus reducing the assembly cost. At the same time, the integrated design also reduces the errors that may occur during the assembly process and improves the assembly accuracy of the compressor fixing structure 100. In addition, setting the first vibration damper 2 and the bracket 1 as an integral part can avoid the problem of the first vibration damper 2 loosening or falling off during the operation of the compressor 7, can 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.

[0051] 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 bracket 1 and a second vibration damping member 3 for reducing the vibration transmission between the bracket 1 and the fixing member 8 on the bracket 1 fixing the compressor 7, a two-level vibration damping structure can be formed, and the structure is simple and easy to implement. It 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. In addition, the first vibration damping member 2 and the bracket 1 are designed as an integral part, which can simplify the structure and assembly process, reduce the number of parts required for assembly, and improve the assembly efficiency. It can also reduce the assembly time, thereby reducing the assembly cost. At the same time, it can avoid the problem of the first vibration damping member 2 loosening or falling off during the operation of the compressor 7, and can improve the structural stability of the compressor fixing structure 100, thereby ensuring the vibration-proof effect of the compressor 7.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, combined Figure 3 and Figure 4 The bracket 1 has a first mounting hole 11 and a second mounting hole 12 on opposite sides thereof, the first vibration damper 2 is inserted into the first mounting hole 11, the compressor fixing structure 100 further includes a nut 4 and a bolt 5, the nut 4 is located on the side of the second mounting hole 12 away from the first mounting hole 11; the bolt 5 is sequentially inserted into the first vibration damper 2, the compressor 7 and the second mounting hole 12 and connected to the nut 4. Figure 1In the example shown, a sleeve 71 may be provided at one end of the compressor 7 close to the bracket 1. By providing the first mounting hole 11 and the second mounting hole 12, it is convenient for the operator to sequentially pass the bolt 5 through the first vibration damping member 2 in the first mounting hole 11, the sleeve 71 of the compressor 7, and the second mounting hole 12, and then fix the bolt 5 with the nut 4 to complete the assembly of the compressor 7, which is convenient for the operator to operate.

[0053] Furthermore, if Figure 3 In the example shown, the operator may also set a nut 6 at the end of the bolt 5 away from the nut 4 to enhance the connection stability between the compressor fixing structure 100 and the compressor 7 .

[0054] In this application, if Figure 3 As shown, a mounting sleeve 19 is provided at a position corresponding to the first mounting hole 11 on the bracket 1, the mounting sleeve 19 and the bracket 1 are integrated, and the first mounting hole 11 passes through the mounting sleeve 19 in the axial direction of the mounting sleeve 19, that is, the mounting sleeve 19 forms a peripheral wall of the first mounting hole 11, which can extend the axial length of the first mounting hole 11 and increase the contact area between the first vibration damping member 2 and the inner peripheral wall of the first mounting hole 11, thereby enhancing the vibration damping effect of the first vibration damping member 2.

[0055] In some embodiments of the present invention, Figure 3 , Figure 4 and Figure 5 As shown, the 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.

[0056] 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 bracket 1, so that the bolt 5 can pass through the first mounting hole 11, the compressor 7 and the second mounting hole 12 in sequence to complete the installation of the compressor 7. The 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.

[0057] In some embodiments of the present invention, Figure 3 , Figure 4 and Figure 5As shown, there are multiple bolts 5, the first mounting hole 11, the second mounting hole 12 and the first vibration damper 2 are all corresponding multiples, and the sleeve 71, the nut 4 and the nut 6 of the compressor 7 are also corresponding multiples. The operator can sequentially pass the multiple bolts 5 through the first vibration damper 2 of the corresponding first mounting hole 11, the sleeve 71 and the second mounting hole 12 of the compressor 7, and then fix the bolts 5 with the nut 4 and the nut 6 respectively to complete the assembly of the compressor 7, which can enhance the connection stability between the compressor fixing structure 100 and the compressor 7. At the same time, there are multiple first vibration dampers 2, 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.

[0058] Furthermore, two first mounting holes 11 for passing two adjacent bolts 5 are arranged on opposite sides of the bracket 1, that is, two first vibration dampers 2 for passing two adjacent bolts 5 are arranged on opposite sides of the bracket 1, so that the first vibration dampers 2 can absorb and disperse the vibration energy of the compressor 7 on opposite sides of the bracket 1, which can further improve the weakening effect of the first vibration damper 2 on the vibration transmission between the compressor 7 and the 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.

[0059] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the first vibration damper 2 includes a bushing 21 and a first rubber sleeve 22. The bushing 21 is inserted into the first mounting hole 11 and sleeved outside the bolt 5. The first rubber sleeve 22 is located in the first mounting hole 11 and sleeved outside the bushing 21. The bushing 21 is inserted into the first rubber sleeve 22 and sleeved outside the bolt 5. The first rubber sleeve 22 can be made of a material with good elasticity such as a rubber member, and the bushing 21 can be made of a material with a certain strength such as stainless steel, which can prevent the bolt 5 from directly contacting the first rubber sleeve 22 and causing the first rubber sleeve 22 to wear. While effectively isolating and reducing the vibration transmission between the compressor 7 and the bracket 1, the service life of the first vibration damper 2 can be extended, and the vibration-proof life of the compressor fixing structure 100 can be extended.

[0060] In some embodiments of the present invention, Figure 6 and Figure 7As shown, washers 23 are sleeved on both ends of the bushing 21 in the axial direction, and the two washers 23 are respectively located on both sides of the axial direction of the first rubber sleeve 22. After the compressor 7 and the bracket 1 are assembled, one of the two axial ends of the first vibration damper 2 abuts against the compressor 7, and the other end abuts against the nut 6. By arranging washers 23 on both sides of the axial direction of the first rubber sleeve 22, the contact area between the first vibration damper 2 and the compressor 7 and the nut 6 can be increased, making the connection more stable. At the same time, the first rubber sleeve 22 can be protected to prevent the compressor 7 and the nut 6 from directly contacting the first rubber sleeve 22 to damage the first rubber sleeve 22, thereby extending the service life of the first vibration damper 2 and ensuring the anti-vibration effect of the first vibration damper 2.

[0061] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the outer peripheral wall of the gasket 23 is flush with the outer peripheral wall of the first rubber sleeve 22. If the diameter of the gasket 23 is too small, the protective effect of the gasket 23 on the first rubber sleeve 22 cannot be guaranteed. If the diameter of the gasket 23 is too large, it is easy to interfere with other components. The gasket 23 and the outer peripheral wall of the first rubber sleeve 22 are set to be flush, which can protect the first rubber sleeve 22 to the greatest extent while ensuring a reasonable structural arrangement, and prevent the compressor 7 and the nut 6 from directly contacting the first rubber sleeve 22 to damage the first rubber sleeve 22, thereby extending the service life of the first vibration damper 2 and ensuring the vibration-proof effect of the first vibration damper 2.

[0062] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the bushing 21 and the gasket 23 are an integral part. For example, the gasket 23 and the bushing 21 can be processed into one piece by a hot riveting process. The number of parts required for assembly can be reduced and the assembly steps can be simplified, thereby reducing the difficulty of assembly and improving the assembly efficiency. Workers do not need to spend extra time to assemble the independent gasket 23 structure separately, thereby reducing the assembly time and thus reducing the assembly cost. At the same time, the structure of the bushing 21 and the gasket 23 is also more stable and strong, and can withstand greater loads and stresses, thereby enhancing the structural strength and stability of the first vibration damping member 2.

[0063] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the gasket 23 is a stainless steel part, which has high tensile strength, hardness and fatigue resistance, can meet various processing needs, and provide convenience for production and processing. At the same time, the high strength, wear resistance and corrosion resistance of the stainless steel part can also ensure the protection effect of the first rubber sleeve 22.

[0064] In some embodiments of the present invention, Figure 6 and Figure 7As shown, along the axial direction of the first rubber sleeve 22, the first rubber sleeve 22 includes a first section 221 and a second section 222 that are connected. The first section 221 is located at an end of the second section 222 that is away from the second mounting hole 12 and has an outer diameter greater than that of the second section 222. The first section 221 cooperates with the inner circumferential wall of the first mounting hole 11.

[0065] It is understandable that the axial length of the first section 221 is slightly greater than the axial length of the first mounting hole 11, which can ensure that the first rubber sleeve 22 has sufficient contact area with the inner circumferential wall of the first mounting hole 11, thereby reducing the vibration transmission to the inner circumferential wall of the first mounting hole 11. The second section 222 is connected to the first section 221 and sleeved outside the bushing 21, which can increase the contact area between the bushing 21 and the first rubber sleeve 22, thereby ensuring the weakening effect of the vibration energy transmitted from the compressor 7 to the bushing 21. By setting the first rubber sleeve 22 as the first section 221 and the second section 222, the bracket 1 and the compressor 7 can be better connected, and the weakening effect of the vibration transmission between the compressor 7 and the bracket 1 can be improved.

[0066] A groove 2214 may be provided on the outer wall of the first section 221 , and the bottom wall of the groove 2214 abuts against the inner wall of the first mounting hole 11 , which can play a role in positioning and limiting, and prevent the first rubber sleeve 22 from falling off from the first mounting hole 11 .

[0067] Furthermore, the first section 221 includes an inner ring segment 2211 and an outer ring segment 2212, and the inner ring segment 2211 and the outer ring segment 2212 are connected by connecting ribs 2213. The connecting ribs 2213 are multiple and are arranged at intervals along the circumferential direction of the inner ring segment 2211 and the outer ring segment 2212. The radial inner end of the connecting rib 2213 is connected to the outer circumferential wall of the inner ring segment 2211, and the radial outer end of the connecting rib 2213 is connected to the inner circumferential wall of the outer ring segment 2212, which can enhance the structural strength of the first section 221, thereby enhancing the vibration reduction effect of the first rubber sleeve 22.

[0068] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the bushing 21 is a stainless steel part, which has high tensile strength, hardness and fatigue resistance, can meet various processing needs, and provide convenience for production and processing. At the same time, the high strength, wear resistance and corrosion resistance of the stainless steel part can also ensure the protection effect of the first rubber sleeve 22.

[0069] Furthermore, the first rubber sleeve 22 is a rubber member with good elasticity, which can effectively absorb and disperse vibration energy, thereby weakening the vibration transmission between the compressor 7 and the bracket 1, and can also reduce the propagation of sound, thereby improving the NVH comfort of the user.

[0070] In some embodiments of the present invention, Figure 2, Figure 3 and Figure 5 As shown, the nut 4 and the bracket 1 are an integral part, and the nut 4 can be welded to the bracket 1, which can reduce the number of parts required for assembly and simplify the assembly steps, thereby reducing the difficulty of assembly and improving the assembly efficiency. Workers do not need to spend extra time to assemble independent nuts 4 separately, thereby reducing assembly hours and further reducing assembly costs. At the same time, integrating the nut 4 and the bracket 1 also makes the structure more stable and strong, and can withstand greater loads and stresses, thereby enhancing the structural strength and stability of the compressor fixing structure 100.

[0071] In some embodiments of the present invention, Figure 2 , Figure 5 and Fig. 9 As shown, the bracket 1 is provided with a pin 16, the fixing member 8 is provided with a fixing hole 81, the pin 16 is at least partially located in the fixing hole 81, and the second vibration damper 3 is at least partially located in the fixing hole 81 and sleeved outside the pin 16. The second vibration damper 3 can be provided with a pin hole, which extends along the axial direction of the second vibration damper 3, the pin 16 is provided on the side of the bracket 1 away from the compressor 7 and is matched and connected with the pin hole, and at least part of the outer peripheral wall of the second vibration damper 3 is matched and connected with the inner peripheral wall of the fixing hole 81. By providing the pin 16, the fixing hole 81 and the second vibration damper 3, it is convenient to connect the bracket 1 and the fixing member 8, which is convenient for assembly, and at the same time, it can ensure the weakening effect of vibration transmission between the bracket 1 and the fixing member 8 and reduce the noise level, thereby improving the NVH comfort of the user.

[0072] Among them, the bracket 1 is provided with multiple pins 16, and the second vibration damping member 3 and the fixing holes 81 are multiple corresponding to the pins 16, so that the bracket 1 is connected to the fixing member 8 at multiple locations, which can further enhance the connection stability between the bracket 1 and the fixing member 8, and at the same time can enhance the weakening effect of vibration transmission between the bracket 1 and the fixing member 8.

[0073] In some embodiments of the present invention, Figure 2 , Figure 5 and Fig. 9 As shown, the second vibration damper 3 and the pin 16 are interference fit, and the outer diameter of the pin 16 is slightly larger than the inner diameter of the pin hole on the second vibration damper 3. By applying a certain pressure, the pin 16 is inserted into the pin hole and fits tightly, which is simple to assemble and can enhance the connection stability between the pin 16 and the second vibration damper 3.

[0074] Furthermore, the second vibration damper 3 is interference fit with the fixing hole 81, and the outer diameter of the second vibration damper 3 is slightly larger than the inner diameter of the fixing hole 81. By applying a certain pressure, the second vibration damper 3 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 second vibration damper 3 and the fixing member 8.

[0075] In some embodiments of the present invention, Figure 1 and Figure 8 As shown, along the axial direction of the second vibration damper 3, the second vibration damper 3 includes a third section 31 and a fourth section 32 connected, the outer diameter of the third section 31 is larger than the outer diameter of the fourth section 32 and larger than the inner diameter of the fixing hole 81, the third section 31 is located outside the fixing hole 81 and between the bracket 1 and the fixing member 8, and at least part of the fourth section 32 is located in the fixing hole 81 and cooperates with the fixing hole 81. The third section 31 is sleeved on the pin 16 and located between the bracket 1 and the fixing member 8, which can avoid direct rigid contact between the bracket 1 and the fixing member 8, thereby reducing the vibration transmission between the bracket 1 and the fixing member 8 and ensuring the vibration-proof effect of the second vibration damper 3. At least part of the fourth section 32 is located in the fixing hole 81 and has an interference fit with the fixing hole 81. By setting the fourth section 32, it is convenient to assemble the second vibration damper 3 with the fixing member 8, and at the same time, the vibration-proof effect between the bracket 1 and the fixing member 8 can be ensured.

[0076] In some embodiments of the present invention, Figure 8 As shown, along the axial direction of the second vibration damper 3, the fourth section 32 includes a matching section 321 and an entry section 322, the matching section 321 is arranged close to the third section 31 relative to the entry section 322, the outer diameter of the matching section 321 is larger than the outer diameter of the entry section 322, and the matching section 321 is interference fit with the fixing hole 81. The outer diameter of the matching section 321 is slightly larger than the inner diameter of the fixing hole 81, so that the matching section 321 can achieve an interference fit with the fixing hole 81, thereby ensuring the connection stability between the fourth section 32 and the fixing member 8. Furthermore, the outer diameter of the entry section 322 gradually decreases in the direction away from the mating section 321, and the outer diameter of the end of the entry section 322 away from the mating section 321 can be slightly smaller than the inner diameter of the fixing hole 81, thereby facilitating the insertion of the entry section 322 into the fixing hole 81 and guiding the mating section 321 into the fixing hole 81, which can save the operator the force required to insert the fourth section 32 into the fixing hole 81, reduce the difficulty of assembling the second vibration damper 3 and the fixing member 8, and thus improve the assembly efficiency.

[0077] In some embodiments of the present invention, Figure 8 As shown, the second vibration damper 3 is a rubber member with good elasticity, which can effectively absorb and disperse vibration energy, thereby weakening the vibration transmission between the bracket 1 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.

[0078] In some embodiments of the present invention, Figure 3As shown, the bracket 1 has a weight-reducing hole 17, which can penetrate the first plate 13 in the thickness direction of the first plate 13. Without affecting the performance of the bracket 1, the weight of the bracket 1 can be reduced, and the lightweight design of the bracket 1 can be realized, thereby reducing the load of the fixing member 8, which is conducive to ensuring the connection stability between the bracket 1 and the fixing member 8. Of course, without affecting the performance of the bracket 1, the weight-reducing hole 17 can also be set on the second plate 14 and the third plate 15, and there can be multiple weight-reducing holes 17. The position, number and shape of the weight-reducing holes 17 are not specifically limited in this application.

[0079] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the bracket 1 has a marking hole 18 for indicating the installation direction of the compressor 7. Figure 3 In the example shown, the identification hole 18 may be a triangular hole provided on the first plate 13, and 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 5, the end of the compressor 7 provided with the wiring harness assembly is provided in the direction of the angle provided in the identification hole 18, so as to prevent the operator from installing the compressor 7 upside down, thereby affecting the subsequent assembly and use.

[0080] A vehicle according to an embodiment of the present invention is described below.

[0081] The vehicle according to the embodiment of the present utility model comprises: a fixing member 8 and the above-mentioned compressor fixing structure 100 .

[0082] Specifically, Figure 1 and Figure 2 As shown, combined Figure 3 and Figure 4 The compressor fixing structure 100 includes a bracket 1, a first vibration damper 2 and a second vibration damper 3. The bracket 1 is used to fix the compressor 7 and is connected to the fixing member 8. The first vibration damper 2 is arranged on the bracket 1 and is an integral part with the bracket 1, and is used to reduce the vibration transmission between the compressor 7 and the bracket 1. The second vibration damper 3 is arranged on the bracket 1 and between the fixing member 8 and the bracket 1, and is used to reduce the vibration transmission between the bracket 1 and the fixing member 8 on which the compressor 7 is installed.

[0083] It is understandable that the compressor 7 and the bracket 1 can be connected by fasteners such as bolts 5 and nuts 4, and the compressor 7 is installed on the fixing member 8 through the bracket 1, which is convenient for the operator to assemble. The first vibration damper 2 and the second vibration damper 3 can be rubber parts, which can effectively absorb and disperse vibration energy. The first vibration damper 2 is arranged on the bracket 1 and connected to the compressor 7, which can reduce the vibration transmission between the compressor 7 and the bracket 1. The second vibration damper 3 is arranged between the bracket 1 and the fixing member 8, which can prevent the vibration transmitted from the compressor 7 to the bracket 1 from being directly transmitted to the fixing member 8, providing an additional vibration reduction effect. When the compressor 7 is applied to a vehicle, the compressor fixing structure 100 can prevent the steering wheel or floor in the vehicle from resonating due to excessive vibration of the compressor 7.

[0084] By setting the first vibration damper 2 and the second vibration damper 3, a two-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 bracket 1 to form the first-stage vibration damping, effectively reducing the vibration impact of the compressor 7 on the bracket 1 when it is working. The second vibration damper 3 can form the second-stage vibration damping, further reducing the vibration transmission between the bracket 1 and the fixing member 8, thereby ensuring that the transmission of the vibration energy of the compressor 7 is weakened to the greatest extent, enhancing the anti-vibration effect of the compressor fixing structure 100, and reducing the vibration of the vehicle.

[0085] In addition, the secondary vibration damping structure formed by the first vibration damping member 2 and the second vibration damping member 3 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.

[0086] Among them, the first vibration damper 2 can be a rubber pad, and the first vibration damper 2 is combined with the bracket 1 into one body 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 thus reducing the assembly cost. At the same time, the integrated design also reduces the errors that may occur during the assembly process and improves the assembly accuracy of the compressor fixing structure 100. In addition, setting the first vibration damper 2 and the bracket 1 as an integral part can avoid the problem of the first vibration damper 2 loosening or falling off during the operation of the compressor 7, can 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.

[0087] 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 bracket 1 and a second vibration damping member 3 for reducing the vibration transmission between the bracket 1 and the fixing member 8 on the bracket 1 fixing the compressor 7, a two-stage vibration damping structure can be formed, and the structure is simple and easy to implement. It 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. In addition, the first vibration damping member 2 and the bracket 1 are designed as an integral part, which can simplify the structure and assembly process, reduce the number of parts required for assembly, and improve the assembly efficiency. It can also reduce the assembly time, thereby reducing the assembly cost. At the same time, it can avoid the problem of the first vibration damping member 2 loosening or falling off during the operation of the compressor 7, and can improve the structural stability of the compressor fixing structure 100, thereby ensuring the vibration-proof effect of the compressor 7 and weakening the vibration transmitted to the vehicle by the compressor 7.

[0088] 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 NVH comfort of the user.
