[0002] In vehicles, compressors are typically mounted on the front subframe or engine compartment longitudinal beams via compressor brackets.

[0003] During the operation of the compressor, the compressor will generate vibration. This vibration will be transmitted to the vehicle body through the compressor bracket, and then to the passenger compartment, causing vibration and noise in the passenger compartment, thus affecting the vibration and noise performance of the entire vehicle.

[0004] How to reduce the vibration energy transmitted to the passenger compartment during compressor operation, thereby optimizing the vibration and noise performance of the whole vehicle, is an urgent problem to be solved. Utility Model Content

The bracket body includes a first sub-part and a second sub-part. The vibration isolation bushing is disposed on the first sub-part and is connected to the compressor. The second sub-part is provided with a mounting part, and the second sub-part is connected to the cabin crossbar in the cabin frame by a first fastener that cooperates with the mounting part; The flexible member is disposed on the second sub-part, the flexible member protrudes from the second sub-part toward the compressor, and a gap is formed between the flexible member and the compressor.

[0007] Furthermore, the number of flexible components is two, and the two flexible components are arranged at intervals along the width direction of the compressor bracket.

[0008] Furthermore, the flexible component is located below the compressor, and the distance between the flexible component and the compressor along the height direction of the compressor bracket is 10mm-15mm.

[0009] Furthermore, the mounting part includes a first mounting part and a second mounting part, the cabin crossbar includes a first cabin crossbar and a second cabin crossbar adjacent to the first cabin crossbar, the second sub-part is connected to the first cabin crossbar by a first fastener that cooperates with the first mounting part, and the second sub-part is also connected to the second cabin crossbar by a first fastener that cooperates with the second mounting part.

[0010] Furthermore, the first mounting part is a first mounting hole, and the second mounting part is a second mounting hole. Both the first mounting hole and the second mounting hole are oblong in shape, and the length directions of the first mounting hole and the second mounting hole are perpendicular.

[0016] The beneficial effects of this utility model are: In this embodiment of the invention, the compressor is connected to a vibration-damping bushing in the compressor bracket. This bushing effectively reduces the vibration energy transmitted to the compressor bracket during compressor operation, thereby effectively reducing the vibration energy transmitted to the passenger compartment. The compressor is mounted on the engine compartment crossbeam via the compressor bracket. During compressor operation, vibration energy is transmitted from the compressor, compressor bracket, engine compartment crossbeam, and engine compartment longitudinal beam to the front panel of the vehicle. Compared to mounting the compressor on the engine compartment longitudinal beam, this increases the path of vibration energy transmission from the compressor to the front panel, reducing the vibration energy transmitted to the front panel and further reducing the vibration energy transmitted to the passenger compartment during compressor operation. This optimizes the overall vehicle vibration and noise performance, ensuring ride comfort. Furthermore, when the compressor operates and vibrates, the protruding flexible component contacts the compressor, preventing direct contact between the vibrating compressor and the bracket body, thus avoiding impact noise and further optimizing the overall vehicle noise performance. In summary, this compressor mounting structure optimizes the overall vehicle vibration and noise performance, achieving excellent performance indicators. Attached Figure Description

Detailed Implementation

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] During compressor operation, the compressor generates vibrations, which are transmitted to the vehicle body via the compressor bracket and then to the passenger compartment, causing vibrations and noise within the passenger compartment and affecting the overall vibration and noise performance of the vehicle. How to reduce the vibration energy transmitted to the passenger compartment during compressor operation, thereby optimizing the overall vehicle vibration and noise performance, is a pressing problem that needs to be solved. To address the above problems, this utility model proposes a compressor mounting structure and a vehicle. The compressor mounting structure and vehicle mentioned above are described in detail below.

[0022] Reference Figures 1 to 4 The compressor mounting structure provided in this embodiment includes a compressor bracket 10, a compressor 20, and an engine compartment frame 30. The compressor 20 is mounted on a crossbar in the engine compartment frame 30 via the compressor bracket 10. Both the compressor 20 and the compressor bracket 10 are located in the front engine compartment of the vehicle. The rear end of the engine compartment frame 30 is connected to a front wall panel 60 of the vehicle, and both the compressor 20 and the compressor bracket 10 are located on the front side of the front wall panel 60. The engine compartment frame 30 also includes engine compartment longitudinal beams, with the crossbars extending along the width direction of the vehicle and the longitudinal beams extending along the length direction of the vehicle.

[0023] The compressor bracket 10 includes a bracket body 11, a vibration isolation bushing 12, and a flexible member 13. The bracket body 11 includes a first sub-part 111 and a second sub-part 112. The vibration isolation bushing 12 is disposed on the first sub-part 111 and is connected to the compressor 20. The second sub-part 112 is provided with a mounting part and is connected to the engine compartment crossbar by a first fastener 40 that cooperates with the mounting part. The flexible member 13 is disposed on the second sub-part 112 and protrudes from the second sub-part 112 toward the compressor 20, and a gap is formed between the flexible member 13 and the compressor 20.

[0024] The first sub-part 111 is specifically the vertically arranged portion of the bracket body 11. The first sub-part 111 provides a location for the installation of the vibration isolation bushing 12, which is connected to the compressor 20. The second sub-part 112 is specifically the horizontally arranged portion of the bracket body 11. The second sub-part 112 is used to connect to the nacelle crossbar and provides a location for the installation of the flexible component 13. (Refer to...) Figure 2 , Figure 3 and Figure 4 The compressor 20 is located on the front side of the first sub-section 111 and on the upper side of the second sub-section 112, which is connected to the top of the cabin crossbar.

[0025] The number of vibration isolation bushings 12 can be multiple, such as two, three, or four. As an example, there are three vibration isolation bushings 12 arranged in a triangular pattern, with the first sub-part 111 correspondingly arranged in a fan-like shape. The compressor 20 is specifically connected to the vibration isolation bushings 12 via a second fastener 50. The vibration isolation bushing 12 can be composed of an outer sleeve, an inner sleeve, and a rubber body. A through hole is provided on the first sub-part 111, and the outer sleeve is interference-fitted with the inner wall of the through hole. The compressor 20 is connected to the inner sleeve of the vibration isolation bushing 12 via the second fastener 50.

[0026] The mounting part can be a mounting hole, a mounting sleeve, a welding nut, etc. Preferably, the mounting part is a mounting hole, which can be circular, oblong, etc., in which case the first fastener 40 passes through the mounting hole. The second sub-part 112 can be connected to one or two engine room crossbars. The first fastener 40 and the second fastener 50 are threaded fasteners, such as bolts, screws, etc.

[0027] The flexible component 13 can be made of rubber, silicone, or other materials. The flexible component 13 can be in the form of a strip, a block, or other shapes. There can be one or more flexible components 13. A groove can be formed on the second sub-part, with a portion of the flexible component 13 extending into the groove and interlocking with it. The remaining portion of the flexible component 13 protrudes from the second sub-part 112 towards the compressor 20. Alternatively, the second sub-part can be without a groove; in this case, the flexible component 13 can be directly bonded to the surface of the second sub-part 112.

[0028] In this embodiment of the invention, the compressor 20 is connected to the vibration isolation bushing 12 in the compressor bracket 10. The vibration isolation bushing 12 effectively reduces the vibration energy transmitted to the compressor bracket 10 during the operation of the compressor 20, thereby effectively reducing the vibration energy transmitted to the passenger compartment. The compressor 20 is mounted on the engine compartment crossbar via the compressor bracket 10. During the operation of the compressor 20, the vibration energy is transmitted to the front wall panel 60 of the vehicle via the compressor 20, the compressor bracket 10, the engine compartment crossbar, and the engine compartment longitudinal beam. Compared to mounting the compressor 20 on the engine compartment longitudinal beam, this increases the path of vibration energy transmission from the compressor 20 to the front wall panel 60 of the vehicle, reducing the vibration energy transmitted to the front wall panel 60. This further reduces the vibration energy transmitted to the passenger compartment during the operation of the compressor 20, thereby optimizing the vibration and noise performance of the entire vehicle and ensuring driving comfort. Furthermore, when the compressor 20 operates and vibrates, the protruding flexible member 13 contacts the compressor 20, preventing the vibrating compressor 20 from directly contacting the bracket body 11 and causing knocking noises, thereby further optimizing the overall vehicle noise performance. In summary, this compressor mounting structure optimizes the vibration and noise performance of the entire vehicle, enabling it to achieve excellent performance indicators.

[0029] In some embodiments, refer to Figure 1 and Figure 2 The number of flexible components 13 is two. In this embodiment, the flexible component 13 is block-shaped. Specifically, refer to... Figure 1 The flexible component 13 can be in the form of a hemispherical block. (Refer to...) Figure 2 The flexible component 13 can also be in the form of a flat cylindrical block.

[0030] Reference Figure 1 and Figure 2 Two flexible members 13 are arranged at intervals along the width direction of the compressor bracket 10. The width direction of the compressor bracket 10 can be referenced... Figure 1 , Figure 3 and Figure 4 As shown in the diagram, the width direction of the compressor bracket 10 is aligned with the width direction of the vehicle. The length direction of the compressor bracket 10 can be referenced... Figure 1 , Figure 3 and Figure 4 As shown in the X direction, the length direction of the compressor bracket 10 is consistent with the length direction of the vehicle. Along the Y direction, the compressor 20 has a certain length, and two flexible members 13 are arranged at intervals along the Y direction, which can effectively prevent the vibrating compressor 20 from directly contacting the bracket body 11.

[0031] In some embodiments, refer to Figure 2 and Figure 4The second sub-section 112 is connected to the upper part of the nacelle crossbar. The compressor 20 is located on the upper side of the second sub-section 112, and the flexible member 13 is located below the compressor 20. Specifically, the flexible member 13 is located between the bottom of the compressor 20 and the second sub-section 112. The flexible member 13 is specifically located on the second sub-section 112 at the position closest to the bottom of the compressor 20.

[0032] Along the height direction of the compressor bracket 10, the distance between the flexible member 13 and the compressor 20 is 10mm-15mm to allow space for the vertical vibration of the compressor 20. The distance between the flexible member 13 and the compressor 20 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc. Preferably, the distance between the flexible member 13 and the compressor 20 along the height direction of the compressor bracket 10 is 15mm.

[0033] In some embodiments, the mounting portion includes a first mounting portion and a second mounting portion, as shown in the figure. Figure 4 The cabin crossbar includes a first cabin crossbar 31 and a second cabin crossbar 32 adjacent to the first cabin crossbar 31. The second sub-part 112 is connected to the first cabin crossbar 31 by a first fastener 40 that cooperates with the first mounting part. The second sub-part 112 is also connected to the second cabin crossbar 32 by a first fastener 40 that cooperates with the second mounting part.

[0034] In this embodiment, the first engine compartment crossbar 31 is located in front of the second engine compartment crossbar 32, and the second engine compartment crossbar 32 is located between the first engine compartment crossbar 31 and the front wall panel 60 of the vehicle. The first fastener 40 mates with both the first mounting part and the second mounting part. The structures of the first mounting part and the second mounting part can be the same or different. In this embodiment, the compressor bracket 10 is mounted on the two engine compartment crossbars, which ensures the stability and reliability of the compressor bracket 10.

[0035] In some embodiments, the first mounting portion is a first mounting hole 1121, and the second mounting portion is a second mounting hole 1122. Both the first mounting hole 1121 and the second mounting hole 1122 are waist-shaped, and the length directions of the first mounting hole 1121 and the second mounting hole 1122 are perpendicular.

[0036] The first mounting hole 1121 and the second mounting hole 1122 are both through holes. There is one first mounting hole 1121 and two second mounting holes 1122. The second sub-part 112 is connected to the first engine room crossbar 31 and the second engine room crossbar 32 by three first fasteners 40 that pass through one first mounting hole 1121 and two second mounting holes 1122 respectively.

[0037] The length direction of the first mounting hole 1121 can be parallel to the X-direction, and correspondingly, the length direction of the second mounting hole 1122 is parallel to the Y-direction. A first connecting hole corresponding to the first mounting hole 1121 is provided on the first cabin crossbar 31, and a second connecting hole corresponding to the second mounting hole 1122 is provided on the second cabin crossbar 32.

[0038] When at least one of the positions of the first connecting hole, the second connecting hole, and the distance between the first connecting hole and the second connecting hole along the X direction is deviated, the X and / or Y direction positions of the compressor bracket 10 can be adjusted so that one first mounting hole 1121 and two second mounting holes 1122 correspond to one first connecting hole and two second connecting holes respectively, thus ensuring the normal assembly of the compressor bracket 10.

[0039] In some embodiments, the bracket body 11 is made of fiber-reinforced composite material.

[0040] Fiber-reinforced composites are a class of lightweight, high-strength materials composed of fiber reinforcements and matrix materials. Fiber-reinforced composites can include glass fiber reinforced composites, carbon fiber reinforced composites, etc. The matrix material of fiber-reinforced composites can be PP (polypropylene), PA (polyamide), etc. As an example, a fiber-reinforced composite material can be PP-LGF40 (long glass fiber reinforced polypropylene, glass fiber mass fraction 40%).

[0041] While maintaining the strength of the bracket body 11, the bracket body 11 made of fiber-reinforced composite material is lighter than that made of metal, thus reducing the overall weight of the compressor bracket 10 and achieving weight reduction. Furthermore, for new energy vehicles, the reduced weight of the compressor bracket 10 reduces the overall weight of the vehicle, effectively improving its range.

[0042] In some embodiments, refer to Figure 1 The first sub-part 111 includes a grid-like reinforcing structure, which includes a plurality of first stiffeners 1111 and a plurality of second stiffeners 1112, each of the second stiffeners 1112 intersecting with at least a portion of the first stiffeners 1111. By providing the grid-like reinforcing structure, the weight of the bracket body 11 can be reduced on the one hand, while ensuring the strength of the bracket body 11 made of fiber-reinforced composite material on the other.

[0043] The number of first stiffeners 1111 can be 5 to 15, and the number of second stiffeners 1112 can be 2 to 5.

[0044] In some embodiments, the nacelle frame 30 further includes a right longitudinal beam 33, the orthographic projection of the compressor 20 along the height direction overlaps with the orthographic projection of the right longitudinal beam 33 along the height direction, that is, the installation position of the compressor bracket 10 is close to the right longitudinal beam 33. Along the Y direction, the distance between the center point of the first mounting hole 1121 and the right longitudinal beam 33 is less than the width of the right longitudinal beam 33. The compressor bracket 10 is mounted on two nacelle crossbars, and the installation position of the compressor bracket 10 is close to the right longitudinal beam 33, which can ensure the dynamic stiffness of the installation location of the compressor bracket 10.

[0045] The nacelle frame 30 also includes a left nacelle longitudinal beam 34 opposite to the right nacelle longitudinal beam 33. The compressor 20 is installed away from the left nacelle longitudinal beam 34, that is, away from the driver's seat of the vehicle, which helps to reduce the vibration and noise transmitted to the driver's seat, the main sensing area.

[0046] Along the length of the compressor bracket 10, the distance between the compressor bracket 10 and the front end of the right longitudinal beam 33 of the engine compartment is greater than the distance between the compressor bracket 10 and the rear end of the right longitudinal beam 33 of the engine compartment. In other words, the installation positions of the compressor bracket 10 and the compressor 20 are closer to the rear end of the right longitudinal beam 33 of the engine compartment.

[0047] It should be noted that the aforementioned front-back, up-down, and left-right orientations are consistent with the front-back, up-down, and left-right orientations of the vehicle.

[0048] This utility model embodiment also provides a vehicle that includes the above-described compressor mounting structure.

[0049] Since the vehicle includes the aforementioned compressor mounting structure, it also possesses the beneficial effects of the aforementioned compressor mounting structure, which will not be elaborated upon here.

[0050] The vehicle can be a sedan, commercial vehicle, SUV, sports utility vehicle, etc. It can be a gasoline-powered vehicle or a new energy vehicle, such as a pure electric vehicle or a hybrid vehicle.

[0051] In this utility model, unless otherwise explicitly defined, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] In this invention, the terms “first,” “second,” “third,” “fourth,” etc. (if present) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0053] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
