[0036] As Figures 1 - 11 shown, a vibration damping structure of a parking air conditioner compressor bracket includes a fixed seat 1 and at least two fixing rings. The fixing rings are arranged on the outer side of the compressor main body 2. The fixed seat 1 is fixedly connected to the parking air conditioner, and a buffer beam 3 is arranged on the upper part of the fixed seat 1;

[0037] The fixing ring includes two fixing parts 4 and two buffer parts 5. The fixing part 4 is connected to the fixing column on the outer side of the compressor main body 2. The middle part of the buffer part 5 is connected to the outer end of the buffer beam 3, and the two ends of the buffer part 5 are slidably connected to the outer ends of the two fixing parts 4.

[0038] There are connecting ears on the outside of the compressor main body 2. The fixing column passes through the connecting ears, and the end of the fixing column is fixed by a nut. The two buffer parts 5 are connected between the two fixing parts 4. The two fixing parts 4 are arranged oppositely, and the two buffer parts 5 are arranged oppositely.

[0039] As Figure 1 and Figure 9 shown, the fixed seat 1 includes a horizontal section connected to the parking air conditioner and two vertical sections connected to the fixing rings. The two vertical sections are connected to both ends of the horizontal section;

[0040] A buffer groove 24 is arranged in the middle of the buffer beam 3. The upper part of the vertical section is located inside the buffer groove 24, and a buffer spring piece 7 is connected between the buffer groove 24 and the upper part of the vertical section.

[0041] The fixing base 1 is evenly provided with connecting screw holes for accommodating connecting nails or fixing bolts. The fixing base 1 is of a rigid structure. A connecting groove is formed by the upper depression of the buffer beam 3. The buffer spring pieces 7 are arranged in an X shape. Buffer elastic layers are provided at the connection between the buffer spring and the buffer groove 24 and at the connection between the buffer spring and the connecting groove.

[0042] As Figure 6 and Figure 10 shown, a buffer cavity 6 is provided inside the outer end of the fixing part 4. The buffer cavity 6 is filled with buffer liquid. The buffer part 5 is hermetically connected to the opening of the buffer cavity 6. A communicating pipe 8 is connected between the buffer cavities 6 at the opposite ends of the two fixing parts 4. The end of the communicating pipe 8 is Y-shaped;

[0043] A sealing piece 9 is connected to the outer end of the buffer part 5. The sealing piece 9 is in contact with and seals the inner wall of the buffer cavity 6. The sealing piece 9 divides the buffer cavity 6 into a pressure increasing area 10 and a pressure releasing area 11. The pressure increasing area 10 and the pressure releasing area 11 are respectively connected to the two branches at the end of the communicating pipe 8.

[0044] The buffer cavity 6 is arranged along the arc direction of the fixing part 4. The buffer cavity 6 has the same curvature as the buffer part 5. When the compressor main body 2 vibrates, the buffer part 5 can move into the buffer cavity 6. When the buffer part 5 moves into the buffer cavity 6, the buffer part 5 moves towards the pressure increasing area 10, the hydraulic pressure inside the pressure increasing area 10 increases, and the buffer liquid will flow towards the pressure releasing area 11 to achieve pressure relief.

[0045] As Figure 9 and Figure 11 shown, the buffer part 5 includes a support section 12 connected to the buffer beam 3 and a connection section 13 connected to the outer end of the support section 12. The outer end of the connection section 13 is slidably connected to the fixing part 4;

[0046] A connection groove 14 is provided at the outer end of the support section 12. The end of the connection section 13 is slidably connected to the connection groove 14.

[0047] The connection groove 14 is arranged opposite to the buffer cavity 6. When the compressor main body 2 vibrates, relative movement occurs between the connection section 13 and the support section 12.

[0048] As Figure 11 shown, a connection seat 15 is provided at the bottom of the connection groove 14. A connecting rod 16 is provided at the axis of the connection seat 15. A guiding block 17 is provided at the outer end of the connecting rod 16;

[0049] A connecting block 18 is rotatably connected to the inner side of the end of the connecting section 13. A connecting hole 19 is provided in the axial direction of the connecting block 18. A spiral guiding groove 20 is provided in the inner wall of the connecting hole 19. The guiding block 17 is slidably arranged inside the guiding groove 20.

[0050] The connecting seat 15 and the connecting rod 16 are coaxially arranged. When the connecting section 13 moves towards the supporting section 12, the connecting block 18 approaches the connecting rod 16, causing the guiding block 17 to move along the guiding groove 20, and the connecting block 18 rotates under the action of force.

[0051] As Figure 5 and Figure 11 As shown, a connecting bearing 21 is provided between the connecting block 18 and the connecting section 13. Two magnetic attraction components are provided at one end of the connecting block 18 opposite to the connecting seat 15 and are symmetrically arranged along the circumferential direction of the connecting block 18. The magnetic attraction components include a plurality of connecting magnetic blocks 22, and the magnetism of the plurality of connecting magnetic blocks 22 increases in sequence;

[0052] Two limiting magnetic blocks 23 are provided on the side of the connecting seat 15 opposite to the connecting block 18. The magnetism of the limiting magnetic blocks 23 is the same as that of the connecting magnetic blocks 22. The two limiting magnetic blocks 23 are respectively arranged opposite to the two magnetic attraction components. When the connecting section 13 extends into the supporting section 12, the connecting block 18 rotates under the action of the guiding block 17, causing the plurality of connecting magnetic blocks 22 with increasing magnetism to be arranged opposite to the limiting magnetic blocks 23 in sequence.

[0053] The two magnetic attraction components are symmetrically arranged to form a ring, and the magnetism of the two magnetic attraction components is centrosymmetrically arranged. In the initial state, the connecting magnetic blocks 22 with the smallest magnetic force of the two magnetic components are arranged opposite to the two limiting magnetic blocks 23.

[0054] As Figure 1 As shown, both the fixing part 4 and the buffer part 5 are arc-shaped, and the inner side of the fixing part 4 is adjacent to the outer wall of the compressor main body 2.

[0055] Both the connecting seat 15 and the connecting block 18 are arc-shaped. The connecting rod 16 is made of rigid silica gel or rigid rubber. When the connecting section 13 extends into the fixing part 4, the connecting rod 16 can be deformed. The connecting seat 15 and the connecting block 18 are both arranged along the circular direction of the fixing ring. The connecting rod 16 has a certain elasticity and can be slightly bent.

[0056] Usage method:

[0057] When the device is specifically used, the fixing ring is arranged on the outer side of the compressor main body 2, so that the fixing column passes through the fixing part 4, and both ends of the fixing column are firmly connected to the compressor main body 2;

[0058] When the compressor main body 2 operates, the compressor main body 2 generates vibrations. The vibrations of the compressor are transmitted to the buffer beam 3 through the fixing ring, and the vibrations between the buffer beam 3 and the fixing seat 1 are buffered by the buffer spring pieces 7, reducing the vibrations of the equipment in the horizontal direction;

[0059] Meanwhile, relative movement occurs between the buffer part 5 and the fixing part 4, causing the connecting section 13 of the buffer part 5 to rush into the interior of the buffer cavity 6. The vibrations are buffered by the buffer liquid inside the buffer cavity 6. When the connecting section 13 impacts the interior of the buffer cavity 6, within the same buffer cavity 6, the buffer liquid flows from the pressure increasing area 10 to the pressure releasing area 11; between the two fixing parts 4, the buffer liquid flows from this buffer cavity 6 to the interior of the buffer cavity 6 connected to the other fixing part 4 through the connecting pipe 8;

[0060] When the connecting section 13 and the buffer cavity 6 reach the buffering limit, the connecting section 13 compresses into the connecting groove 14, and the connecting magnet 22 and the limiting magnet 23 are pressed against each other relatively. As they move relatively, the guiding block 17 and the guiding groove 20 rotate relatively, causing the connecting block 18 to rotate;

[0061] When the connecting block 18 rotates, the magnetic force of the connecting magnet 22 arranged opposite to the limiting magnet 23 increases, increasing the repulsive force on the connecting section 13 to counteract the relative impact force between them, achieving vibration reduction.

[0062] Within the same fixing ring, the vibrations of the compressor main body 2 are buffered through the structure of four buffer cavities 6 and four connecting grooves 14. It can buffer the vibration forces in the vertical direction, the lateral direction perpendicular to the buffer beam 3, and other inclined directions perpendicular to the axis of the compressor housing, and can evenly distribute the vibrations, avoiding excessive local stress. Multiple fixing rings can be arranged outside the same compressor main body 2, and at least one or two buffer beams 3 can be connected between adjacent fixing rings.

[0063] The above specific embodiments are only specific cases of the present invention. The patent protection scope of the present invention includes, but is not limited to, the product forms and styles of the above specific embodiments.
