[0043] like Figure 1 、 Figure 2 As shown, the mounting bracket 2 is concave in shape and includes: a base plate, a bent plate and a flat plate; two bent plates and two flat plates are symmetrically installed on both sides of the base plate; the bent plate includes a vertical portion and an inclined portion; the vertical portion is connected to the base plate, and the inclined portion is connected to the flat plate.

[0044] Furthermore, a first mounting hole for mounting the screw rod 4 is provided on the vertical portion; and a second mounting hole for mounting the bolt 3 and the vibration damping pad assembly 1 is provided on the flat plate.

[0045] During implementation, the electric scroll compressor is fixedly connected to the mounting bracket 2 via the screw 4 , and the screw 4 passes through the first mounting hole on the vertical portion and is fastened to the nut 5 .

[0046] Specifically, there are two first mounting holes along the same straight line on two symmetrically arranged bent plates, and the screw 4 passes through the two symmetrical first mounting holes and the compressor casing at the same time, thereby fixing the compressor to the mounting bracket 2.

[0047] Specifically, if Figure 1 As shown, two screw rods 4 are provided, and two groups of first mounting holes are provided front and back on the mounting bracket 2 .

[0048] Specifically, if Figure 1 、 Figure 2 、 Figure 3 As shown, in the present invention, four groups of vibration damping pad assemblies 1 are provided, and correspondingly, four second mounting holes are provided on the plane plate of the mounting bracket 2 .

[0049] Furthermore, if Figure 3 、 Figure 4 As shown, the vibration damping bracket of the present invention further includes a positioning sleeve 6.

[0050] like Figure 3 、 Figure 4 As shown, the bolt 3 is installed inside the positioning sleeve 6; specifically, the positioning sleeve 6 includes a disc portion and a cylindrical portion; the cylindrical portion is sleeved and installed inside the star-shaped mounting hole 1-4 of the first vibration damping pad 1-1; the disc portion is arranged on the upper end surface of the first vibration damping pad 1-1.

[0051] Preferably, the cylindrical portion of the positioning sleeve 6 extends to the lower surface of the second vibration damping pad 1 - 2 .

[0052] Furthermore, if Figure 4 As shown, the first and second vibration-damping pads 1-1, 1-2 are symmetrically positioned above and below the mounting bracket 2 of the electric scroll compressor. A cylindrical mounting portion 105 is provided at the lower end of the first vibration-damping pad 1-1 and the upper end of the second vibration-damping pad 1-2. The mounting portion 105 of the first vibration-damping pad 1-1 is positioned in the second mounting hole of the mounting bracket 2, while a gasket 7 is sleeved on the exterior of the mounting portion 105 of the second vibration-damping pad 1-2.

[0053] like Figure 4 As shown, when in use, the mounting portion 105 of the first vibration damping pad 1-1 cooperates with the second mounting hole on the mounting bracket 2 of the electric scroll compressor, and the mounting portion 105 of the second vibration damping pad 1-2 cooperates with the inner hole of the gasket 7, and the upper and lower ends of the buffer portion of the first vibration damping pad 1-1 are in contact with the bottom surface of the bolt 3 and the upper surface of the mounting bracket 2 respectively, and the upper end surface and lower end surface of the second vibration damping pad 1-2 are in contact with the gasket 7 and the chassis of the automobile respectively, thereby being able to dampen the vibration of the electric scroll compressor when it vibrates, and at the same time reduce the vibration intensity transmitted to the chassis.

[0054] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, the first and second vibration damping pads 1-1 and 1-2 have the same structural shape; however, their sizes differ, with the first vibration damping pad 1-1 being smaller than the second vibration damping pad 1-2. By making the second vibration damping pad 1-2 larger than the first vibration damping pad 1-1, the present invention reduces deformation of the second vibration damping pad 1-2 while achieving vibration buffering and energy dissipation, further reducing vibration energy transmitted to the vehicle chassis and thus reducing chassis vibration.

[0055] The following takes the first vibration damping pad 1-1 as an example to illustrate the specific structure of the vibration damping pad:

[0056] In a specific embodiment of the present invention, Figure 5 、 Figure 6 As shown, the first vibration damping pad 1-1 includes a buffer portion for buffering and isolating vibrations and a mounting portion 105. Both the buffer portion and the mounting portion 105 are cylindrical structures; the diameter of the buffer portion is larger than the diameter of the mounting portion 105.

[0057] like Figure 5 、 Figure 6 As shown, the buffer portion of the first vibration damping pad 1-1 is provided with a first trapezoidal vibration damping groove 101, an annular vibration damping groove 102, and a second trapezoidal vibration damping groove 103. Specifically, as Figure 5 、 Figure 7 As shown, a star-shaped mounting hole 104 extending along its own axial direction is provided at the center of the first vibration-damping pad 1 - 1 ; the star-shaped mounting hole 104 passes through the buffer portion and the mounting portion 105 .

[0058] Specifically, if Figure 7 As shown, a plurality of first trapezoidal vibration-damping grooves 101 are provided on the upper surface of the buffer portion, and the plurality of first trapezoidal vibration-damping grooves 101 are arrayed at equal intervals along the circumferential direction of the buffer portion.

[0059] Specifically, if Figure 5 、 Figure 6 As shown, a plurality of second trapezoidal vibration-damping grooves 103 are provided on the lower surface of the buffer portion, and the plurality of second trapezoidal vibration-damping grooves 103 are arrayed at equal intervals along the circumferential direction of the buffer portion.

[0060] Furthermore, if Figure 5 、 Figure 6 As shown, the first trapezoidal vibration-damping groove 101 and the second trapezoidal vibration-damping groove 103 are symmetrically arranged relative to the central plane of the buffer portion.

[0061] Furthermore, if Figure 5As shown, a first trapezoidal buffer tooth is formed between two adjacent first trapezoidal vibration damping grooves 101, and a second trapezoidal buffer tooth is formed between two adjacent second trapezoidal vibration damping grooves 103. Specifically, the first trapezoidal vibration damping grooves 101 and the first trapezoidal buffer tooth have the same size, and the second trapezoidal vibration damping grooves 103 and the second trapezoidal buffer tooth have the same size.

[0062] Furthermore, if Figure 5 、 Figure 6 、 Figure 7 As shown, the longitudinal cross-sections of the first trapezoidal vibration damping groove 101 and the second trapezoidal vibration damping groove 103 are both isosceles trapezoids that are wide at the top and narrow at the bottom. In addition, the first trapezoidal vibration damping groove 101 and the second trapezoidal vibration damping groove 103 gradually decrease in size from the outside to the center of the vibration damping pad.

[0063] That is to say, the first trapezoidal vibration damping groove 101 extends from the outer side of the buffer part toward the middle star-shaped mounting hole 104, and the size of the first trapezoidal vibration damping groove 101 gradually decreases and is connected to the star-shaped mounting hole 104; the second trapezoidal vibration damping groove 102 extends from the outer side surface of the buffer part to the outer side surface of the mounting part 105, and the size gradually decreases.

[0064] During use, when the electric scroll compressor generates up and down vibrations in the vertical direction, the first trapezoidal buffer teeth and the second trapezoidal buffer teeth can be compressed and deformed, thereby dissipating the vibration energy.

[0065] like Figure 5 、 Figure 6 As shown, the annular vibration-damping groove 102 is provided on the outer side of the buffer portion and is located in the middle of the buffer portion.

[0066] Specifically, the cross section of the annular vibration-damping groove 102 is a circular ring, and the longitudinal section is a combination of a rectangle and a semicircle; the upper side and the lower side of the annular vibration-damping groove 102 are flat surfaces, and the inner side is an arc surface.

[0067] During use, when the electric scroll compressor generates vertical up-and-down vibrations, the entire vibration damping pad is repeatedly compressed and released. This compression of the entire pad also compresses annular vibration damping groove 102, and the upper and lower surfaces of annular vibration damping groove 102 deflect relative to the circular arc surface in opposite directions. Simultaneously, the curvature of the circular arc surface changes. During the compression and release of the entire vibration damping pad, the shape change of annular vibration damping groove 102 dissipates vibration energy and releases the internal energy of the pad after absorbing the vibration energy.

[0068] Furthermore, if Figure 5 、 Figure 6 As shown, the first trapezoidal vibration-damping groove 101 extends from the outer side surface of the buffer portion of the first vibration-damping pad 1 - 1 to the star-shaped mounting hole 104 .

[0069] Furthermore, if Figure 5 、 Figure 6 As shown, the second trapezoidal vibration-damping groove 102 extends from the outer side surface of the buffer portion of the first vibration-damping pad 1 - 1 to the outer side surface of the mounting portion 105 .

[0070] In a specific embodiment of the present invention, the star-shaped mounting hole 104 is composed of a cylindrical hole and a plurality of triangular grooves arranged in an array along the circumference of the cylindrical hole.

[0071] Furthermore, if Figure 3 As shown, the bottom end of the triangular groove and the connecting portion between two adjacent triangular grooves are designed with rounded corners.

[0072] During implementation, the star-shaped mounting hole 104 can follow the vibration of the electric scroll compressor and deform. When the electric scroll compressor generates up and down vibrations and the vibration damping pad is compressed, the tooth-shaped portion between the triangular grooves of the star-shaped mounting hole 104 of the vibration damping pad is deformed, and the angle of the multiple triangular grooves of the star-shaped mounting hole 104 changes; when the electric scroll compressor generates horizontal vibration / lateral vibration, the tooth-shaped portion between the triangular grooves of the star-shaped mounting hole 104 of the vibration damping pad is compressed. Through the deformation of the star-shaped mounting hole 104, the vertical up and down vibrations and the horizontal lateral vibrations can be buffered at the same time, and the internal energy of the vibration damping pad can be released.

[0073] The vibration reduction bracket provided in this embodiment has a significant vibration reduction effect on the electric scroll compressor of the automobile. After vibration reduction, the vibration of the electric scroll compressor is reduced, the noise inside the vehicle is significantly reduced, abnormal noise disappears, and the vibration of the steering wheel is reduced.

[0074] The above description is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
