The embodiments described below by reference to the drawings are exemplary only, and are used only for the purpose of explaining the present application, and should not be understood as a limitation of the present application.

In addition, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0037] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] Reference will now be made to Figures 1-6 The compressor support 10 according to the embodiments of the present application is described below.

[0039] As Figures 1-6As shown, the compressor support 10 according to the embodiment of the utility model, comprising: support body 1, connecting support 2 and connecting piece 3.

[0040] Support body 1 is used to connect compressor 20;Connecting support 2 is used to connect support body 1 and car beam;Connecting piece 3 is used to connect support body 1 and connecting support 2, the axial direction of connecting piece 3, the arrangement direction of support body 1 and compressor 20 and up-down direction are mutually perpendicular two by two.

[0041] It can be understood that compressor 20 and compressor support 10 are subjected to the force of gravity, and are subjected to downward force, and because the axial direction of connecting piece 3 and the up-down direction are mutually perpendicular two by two, so that connecting piece 3 can be subjected to force in the radial direction, when connecting piece 3 is subjected to force in the radial direction, it is more suitable that compressor 20 is hung on the car beam, so that the vibration mode and dynamic stiffness of compressor assembly 100 have obvious advantages, and resonance caused by the operation of compressor 20 can be effectively reduced, and the driving comfort is improved.

[0042] Among them, it needs to be explained that when connecting piece 3 is subjected to radial force, the material of connecting piece 3 mainly bears shear stress. Shear stress usually causes the material to produce large deformation, but because of the structural design of connecting piece 3 (such as multi-layer metal sheet or rubber layer), the shear stiffness is high, which can effectively resist deformation, so the dynamic stiffness is large, the natural frequency is high, the resonance is effectively reduced, and the vibration mode is better. When connecting piece 3 is subjected to axial force, the material of connecting piece 3 mainly bears compression or tensile stress. Compression or tensile stress can cause connecting piece 3 to deform in the thickness direction, and the stiffness of connecting piece 3 in the thickness direction is usually low, so the dynamic stiffness is small, the natural frequency is low, and resonance is easy to produce, and the vibration mode is poor.

[0043] At the same time, when connecting piece 3 is subjected to radial force, the geometry of connecting piece 3 can better disperse and absorb force, so as to show high dynamic stiffness and good vibration mode. The material of connecting piece 3 usually has anisotropy, that is, the mechanical properties in different directions are different. This anisotropy causes the dynamic stiffness of connecting piece 3 when subjected to radial force to be greater than the dynamic stiffness when subjected to axial force.

[0044] When subjected to axial force, vibration energy is mainly transmitted through compression or tensile deformation, and the deformation ability of connecting piece 3 in the axial direction is strong, which causes low dynamic stiffness. When subjected to radial force, vibration energy is mainly transmitted through shear deformation, and the design of connecting piece 3 through radial force can usually effectively inhibit this shear deformation, so as to show high dynamic stiffness.

[0045] For example, in the utility model, through NVH (Noise, Vibration, Harshness) analysis, the vibration mode of the compressor assembly 100 is above 900Hz, and the equivalent dynamic stiffness of each connecting piece 3 mounting point is greater than 4000N / mm.

[0046] In addition, the axis direction of the connecting piece 3 is perpendicular to the arrangement direction of the bracket body 1 and the compressor 20, and the diameter of the structure for damping in the connecting piece 3, such as the rubber pad 31, is generally greater than its thickness.

[0047] Further, the bracket body 1 and the connecting bracket 2 can be aluminum parts, which have high strength and low density, so that the bracket body 1 and the connecting bracket 2 have high strength while reducing their own weight.

[0048] According to the compressor bracket 10 of the utility model embodiment, the connecting piece 3 is used to connect the bracket body 1 and the connecting bracket 2, the axis direction of the connecting piece 3, the arrangement direction of the bracket body 1 and the compressor 20, and the up-down direction are perpendicular to each other, so that the connecting piece 3 can be stressed in the radial direction, and when the connecting piece 3 is stressed in the radial direction, it is more suitable for the case that the compressor 20 is hung on the vehicle beam, so that the compressor assembly 100 has obvious advantages in vibration mode and dynamic stiffness, can effectively reduce the resonance caused by the operation of the compressor 20, and improve the driving comfort.

[0049] In some embodiments of the utility model, as shown in Figure 2 , Figure 3 , Figure 5 and Figure 6 , the two ends of the bracket body 1 along the axis direction of the connecting piece 3 are both bent towards the direction away from the compressor 20, the connecting bracket 2 comprises two connecting pieces 21, the two connecting pieces 21 are spaced apart in the axis direction of the connecting piece 3 and are fixed opposite to the vehicle beam, the two connecting pieces 21 are arranged between the two bent portions 11, and the connecting piece 21 and the bent portion 11 on the same side along the axis direction of the connecting piece 3 are connected through the connecting piece 3.

[0050] It can be understood that the two connecting pieces 21 are arranged between the two bending portions 11, and the two connecting pieces 21 are fixed relative to the vehicle beam, thereby limiting the movement of the bending portion 11 in the axial direction of the connecting piece 3, so that the bracket body 1 can be fixed relative to the vehicle beam. The connecting piece 3 is arranged in the connecting piece 21 and the bending portion 11 on the same side along the axial direction of the connecting piece 3, so as to realize that the axial direction of the connecting piece 3, the arrangement direction of the bracket body 1 and the compressor 20 and the up-down direction are perpendicular to each other in pairs.

[0051] It should be noted that the two connecting pieces 21 can be parallel, or the angle between the two connecting pieces 21 can be changed according to actual installation requirements, and the angle between the two bending portions 11 can be adaptively changed.

[0052] In some embodiments of the utility model, as shown in Figure 2 、 Figure 3 、 Figure 5 and Figure 6 , the connecting bracket 2 further comprises a connecting plate 22, the connecting plate 22 extends along the axial direction of the connecting piece 3, the connecting plate 22 is connected with the vehicle beam, and the two ends of the connecting plate 22 along the axial direction of the connecting piece 3 are connected with the two connecting pieces 21 respectively.

[0053] It can be understood that the connecting plate 22 is connected with the vehicle beam, and then the connecting plate 22 is connected with the two connecting pieces 21, so as to realize that the connecting piece 21 is fixed relative to the vehicle beam, and the two ends of the connecting plate 22 along the axial direction of the connecting piece 3 are connected with the two connecting pieces 21 respectively, so as to facilitate the fixing of the spacing between the two connecting pieces 21 and the installation of the connecting bracket 2.

[0054] In some embodiments of the utility model, the connecting piece 21 is directly connected with the vehicle beam. It can be understood that when the vehicle beam is a circular cross-section beam or an irregular cross-section beam, the connecting piece 21 is directly connected with the vehicle beam, so as to facilitate the assembly of the connecting piece 21 and the vehicle beam, and at the same time, the direct connection of the connecting piece 21 and the vehicle beam can also simplify the structure of the connecting bracket 2, save cost and weight. In addition, the connecting piece 21 and the vehicle beam can be connected by welding, or the vehicle beam and the connecting piece 21 can be an integral part.

[0055] In some embodiments of the utility model, as shown in Figure 1 、 Figure 2 and Figure 6 , at least one side of the connecting piece 3 of the compressor bracket 10 on both sides along the axial direction of the connecting piece 3 is a plurality of. For example, in Figure 1 、 Figure 2 and Figure 6In the shown example, the two connecting pieces 3 on both sides of the compressor support 10 along the axial direction of the connecting piece 3 are both multiple (in the present application, the two connecting pieces 3 on both sides are both two), but the present application is not limited thereto, and one of the connecting pieces 3 on one side can be one, and the connecting pieces 3 on the other side can be multiple. Thus, the connection reliability of the support body 1 and the connecting support 2 is improved, and at the same time, relative rotation of the support body 1 and the connecting support 2 can be avoided.

[0056] In some embodiments of the present application, as shown in Figure 6 The gap is provided between the connecting piece 21 and the bent portion 11 on the same side along the axial direction of the connecting piece 3. Thus, the floating adjustment of the connecting piece 21 and the bent portion 11 during connection is facilitated, so as to avoid installation interference between the connecting piece 21 and the bent portion 11, and facilitate the installation of the connecting piece 21 and the bent portion 11. At the same time, hard contact between the connecting piece 21 and the bent portion 11 can be avoided, so as to further improve the damping effect.

[0057] In some embodiments of the present application, as shown in Figures 2-6 The support body 1 is provided with a mounting hole 12, the connecting piece 3 includes a rubber pad 31 and a fastener 32, part of the rubber pad 31 is arranged in the mounting hole 12, the rubber pad 31 abuts against the connecting support 2, and the fastener 32 is arranged in the rubber pad 31 and connected with the connecting support 2.

[0058] It can be understood that the rubber pad 31 is a rubber part and has a certain deformation capacity, so as to play a damping role, the fastener 32 is arranged in the rubber pad 31 and connected with the connecting support 2, so as to realize the connection of the connecting support 2 and the support body 1. The rubber pad 31 abuts against the connecting support 2, so as to avoid hard contact between the connecting support 2 and the support body 1, and further improve the damping effect.

[0059] Further, the support body 1 has the bent portion 11 bent away from the compressor 20 at both ends along the axial direction of the connecting piece 3, the connecting support 2 includes two connecting pieces 21, the two connecting pieces 21 are spaced apart along the axial direction of the connecting piece 3 and fixed relative to the vehicle beam, the two connecting pieces 21 are arranged between the two bent portions 11, and the connecting piece 21 and the bent portion 11 on the same side along the axial direction of the connecting piece 3 are connected through the connecting piece 3. The mounting hole 12 is arranged on the bent portion 11, and the rubber pad 31 abuts against the connecting piece 21.

[0060] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The connecting support 2 is arranged on the side of the support body 1 away from the compressor 20. Thus, the compressor support 10 is conveniently hung on the vehicle beam, so as to facilitate the hanging of the compressor 20 on the vehicle beam.
