Description

Technical Field

[0001] This utility model belongs to the field of compressor technology, and in particular relates to a compressor bracket. Background Technology

[0002] Compressors, as core fluid machinery that converts low-pressure gas into high-pressure gas, are widely used in industrial production, refrigeration and air conditioning, new energy vehicles, medical equipment, and many other fields. Compressor brackets, as key components that fix the compressor, mitigate vibrations generated during operation, and ensure stable equipment operation, directly affect the compressor's operational stability and service life through their structural design and performance. Current compressor bracket designs often have many shortcomings, failing to meet the diverse needs of different application scenarios. Because the vibrations generated during compressor operation cannot be effectively buffered, they are directly transmitted through the rigid bracket to the mounting surface, surrounding equipment, and even the entire working environment. This can easily lead to loosening and fatigue deformation of the bracket's connections, and even failure of the connection between the compressor and the bracket, severely affecting the compressor's operational accuracy and service life. Furthermore, undamped vibrations are converted into significant operating noise. In fields with stringent noise control requirements, such as medical equipment, residential air conditioning, and new energy vehicle cabins, this problem has become a pressing technical challenge.

The shock absorption base is installed on the base, the buffer is installed above the shock absorption base, and the top cover is located above the buffer. The buffer is used to achieve axial and radial contact between the shock absorption base and the connector. The connector passes through the shock absorption base to the top cover and is used to connect the shock absorption base and the top cover. The connector has a connection hole in the center for connecting to the compressor.

The first arc-shaped protrusion has an upward convex structure and is connected to the inner periphery of the first annular plane portion. The center of the first arc-shaped protrusion forms a first through hole for the connector to pass through. The head of the bolt is located below the first arc-shaped protrusion and axially abuts against the first arc-shaped protrusion. A buffer gap is formed between the bolt shank and the radial direction of the first arc-shaped protrusion, and the buffer extends and fills the buffer gap.

[0009] In the above technical solution, the first annular planar portion and the first arc-shaped protrusion portion are integrally formed.

[0011] In the above technical solution, the second annular planar portion and the second arc-shaped protrusion portion are integrally formed.

[0012] In the above technical solution, the buffer is further made of rubber.

[0013] The beneficial effects of this utility model are as follows: 1. The buffer component features a dual axial and radial contact design, which can simultaneously absorb axial and radial vibrations, attenuate vibration transmission, and reduce compressor operating noise; the mounting feet, together with the fixing arm, ensure stable fixation of the bracket, preventing bracket displacement during compressor operation; the shock absorption components and base are detachable, and the connectors have a split structure, allowing for individual replacement of vulnerable parts such as the buffer component without replacing the entire bracket, thus reducing maintenance costs; the connection holes of the connectors and the mounting holes of the mounting feet adopt a universal design, which can be adapted to different models of compressors and various installation scenarios.

[0014] 2. The clamping structure of bolts and nuts ensures a firm connection between the various components of the shock absorber assembly, enabling it to withstand the vibration load during compressor operation and preventing loosening of components. The detachable connector structure simplifies the disassembly process of the shock absorber assembly, requiring no complex tools and allowing for quick replacement of vulnerable components such as buffers, reducing maintenance difficulty and costs. The bolt shank stably transmits the compressor load to the shock absorber seat, working in conjunction with the damping effect of the buffer to ensure a clear force transmission path and improve the overall load-bearing stability of the support.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0017] Example 1: This embodiment provides a compressor bracket, including: Base 1, with a number of mounting feet 11 extending from the bottom of the base 1, mounting feet 11 having mounting holes, and a fixing arm 12 on the side wall of the base 1; The shock-absorbing component 2 is installed on the upper surface of the base 1 and is detachably connected to the base 1; The shock absorption assembly 2 includes a shock absorption seat 21, a buffer 22, a top cover 23, and a connector 24. The shock absorption seat 21 is installed on the base 1, the buffer 22 is installed above the shock absorption seat 21, and the top cover 23 is located above the buffer 22. The buffer 22 is used to achieve axial and radial contact between the shock absorption seat 21 and the connector 24. The connector 24 passes through the shock absorption seat 21 and the top cover 23 and is used to connect the shock absorption seat 21 and the top cover 23. The connector 24 has a connection hole 243 at its center for connecting to the compressor.

[0018] In this embodiment, the bottom edge has several downwardly extending and evenly distributed mounting feet 11, each mounting foot 11 having a through mounting hole; the side wall of the base 1 is provided with a fixing arm 12, and the upper surface of the base 1 is used to install the shock-absorbing component 2. The shock-absorbing component 2 is detachably connected to the base 1, and the whole is composed of a shock-absorbing seat 21, a buffer 22, a top cover 23, and a connecting member 24; the shock-absorbing seat 21 is assembled on the upper surface of the base 1, the buffer 22 is located above the shock-absorbing seat 21, and the top cover 23 covers the buffer 22; the connecting member 24 passes through the shock-absorbing seat 21, the buffer 22, and the top cover 23 in sequence to realize the connection and fixation between the shock-absorbing seat 21 and the top cover 23; the center of the connecting member 24 has a connecting hole 243 through it along the axial direction for connecting with the compressor with a fastener; the buffer 22 is located in the gap area between the shock-absorbing seat 21 and the top cover 23, and at the same time fills the gap between the connecting member 24 and the shock-absorbing seat 21, so as to realize the axial and radial double contact between the shock-absorbing seat 21 and the connecting member 24.

[0019] The buffer component 22 features a dual axial and radial contact design, which can simultaneously absorb axial and radial vibrations, attenuate vibration transmission, and reduce compressor operating noise. The mounting foot 11, together with the fixing arm 12, ensures stable fixation of the bracket, preventing bracket displacement during compressor operation. The shock absorption component 2 and the base 1 are detachable, and the connector 24 has a split structure, allowing for individual replacement of vulnerable components such as the buffer component 22 without replacing the entire bracket, thus reducing maintenance costs. The connecting hole 243 of the connector 24 and the mounting hole of the mounting foot 11 adopt a universal design, which can be adapted to different models of compressors and various installation scenarios.

[0020] Example 2: This embodiment provides a compressor bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0021] The base 1 is rectangular with a hollow center. There are four shock-absorbing components 2, which are installed at the four corners of the base 1.

[0022] In this embodiment, the base 1 is a rectangular structure with a hollowed-out center. This reduces material usage and achieves lightweight design while maintaining the structural strength of the edges and corners. There are four shock-absorbing components 2, which are installed at the four corners of the rectangular base 1 in a rectangular array. The four-point uniform support ensures that the compressor is evenly stressed after installation, reducing shaking caused by uneven stress during operation and improving the stability of the compressor. The four shock-absorbing components 2 provide synchronous shock absorption, which can fully absorb vibrations from all directions of the compressor and further improve the overall shock absorption effect.

[0023] Example 3: This embodiment provides a compressor bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0024] Two fixed arms 12 are provided, which are symmetrically distributed on both sides of the base 1 along the axis of the base 1.

[0025] In this embodiment, there are two fixing arms 12, which are respectively arranged on the two side walls of the base 1 and are symmetrically distributed about the axis of the base 1. The free ends of the fixing arms 12 extend away from the base 1 and are provided with connection holes 243. The double fixing of the fixing arms 12 and the mounting feet 11 effectively prevents the bracket from shifting or shaking during the operation of the compressor, which is especially suitable for high-frequency vibration scenarios. The symmetrical distribution of the two fixing arms 12 makes the auxiliary fixing force evenly distributed, avoids deformation of the base 1 due to force on one side, and extends the service life of the bracket.

[0026] Example 4: This embodiment provides a compressor bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0027] The connector 24 includes a bolt 241 and a nut 242. The head of the bolt 241 is located at the bottom of the damping seat 21 and abuts against the damping seat 21 axially. The shank of the bolt 241 passes through the damping seat 21, the buffer 22, and the top cover 23 in sequence. The nut 242 is located on the top cover 23 and abuts against the top cover 23 axially. The nut 242 is connected to the shank of the bolt 241. The connecting hole 243 is located at the center of the shank of the bolt 241.

[0028] In this embodiment, the connector 24 consists of a bolt 241 and a nut 242. The bolt 241 includes a head and a shank. The head is hexagonal and its outer diameter is larger than the diameter of the central through hole of the shock absorber 21. A connecting hole 243 is axially opened in the center of the shank of the bolt 241. The head of the bolt 241 abuts against the bottom of the shock absorber 21, forming an axial abutment. The shank of the bolt 241 passes through the shock absorber 21, the buffer 22, and the top cover 23 in sequence, extending above the top cover 23. The nut 242 is adapted to be connected to the extension of the shank of the bolt 241, and its bottom abuts against the top cover 23. It cooperates with the head of the bolt 241 to achieve axial clamping and fixing of the shock absorber 21, the buffer 22, and the top cover 23. The clamping structure of bolt 241 and nut 242 ensures a firm connection between the components of the shock absorber assembly 2, which can withstand the vibration load during compressor operation and prevent the components from loosening. The detachable connector 24 structure simplifies the disassembly process of the shock absorber assembly 2, requiring no complicated tools and allowing for quick replacement of vulnerable components such as the buffer 22, reducing maintenance difficulty and cost. The bolt 241 rod can stably transmit the compressor load to the shock absorber seat 21, which, together with the shock absorption effect of the buffer 22, ensures a clear force transmission path and improves the overall load-bearing stability of the bracket.

[0029] Example 5: This embodiment provides a compressor bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0030] The shock absorber seat 21 includes: The first annular planar portion 211 is provided with a plurality of circumferentially distributed fixing holes 2111 for threaded connection between the shock absorber 21 and the base 1. The first arc-shaped protrusion 212 has an upward convex structure and is connected to the inner periphery of the first annular flat portion 211. The center of the first arc-shaped protrusion 212 forms a first through hole for the connector 24 to pass through. The head of the bolt 241 is located below the first arc-shaped protrusion 212 and abuts against the first arc-shaped protrusion 212 axially. A buffer gap is formed between the shank of the bolt 241 and the radial direction of the first arc-shaped protrusion 212, and the buffer member 22 extends and fills the buffer gap.

[0031] In this embodiment, the shock absorber 21 is composed of a first annular flat portion 211 and a first arc-shaped protrusion 212. The first annular flat portion 211 is horizontally arranged and has a plurality of fixing holes 2111 evenly opened along the circumference. The first arc-shaped protrusion 212 has an upwardly convex arc-shaped structure, which can increase its own structural strength and shock absorption effect. The bottom inner circumference is connected to the inner circumference of the first annular flat portion 211, and a first through hole is passed through the center. The first annular flat portion 211 is threaded to the upper surface of the base 1 through the bolt 241 in the fixing hole 2111, so as to realize the detachable fixing of the shock absorber 21 to the base 1. The head of the bolt 241 is located below the first arc-shaped protrusion 212 and abuts against the first arc-shaped protrusion 212 axially. A buffer gap is reserved between the bolt shank and the inner wall of the first through hole of the first arc-shaped protrusion 212, and the buffer member 22 extends to fill the gap. The buffer gap and the filling of the buffer 22 enable the buffer 22 to absorb radial vibration in a targeted manner. Combined with the axial damping structure, it achieves double damping and further improves the overall damping performance. The axial contact between the head of the bolt 241 and the first arc-shaped protrusion 212 effectively restricts the axial movement of the bolt 241, avoids compressor installation misalignment due to bolt 241 displacement, and improves connection stability.

[0032] Example 6: This embodiment provides a compressor bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0033] The first annular flat portion 211 and the first arc-shaped protrusion 212 are integrally formed structures.

[0034] In this embodiment, the first annular flat portion 211 and the first arc-shaped protrusion 212 of the shock absorber 21 are manufactured using an integral molding process, without any splicing gaps, forming a complete integrated structure. This integrated structure has no weak splicing points, allowing it to withstand greater vibration loads and the weight of the compressor, preventing deformation or damage to the shock absorber 21 due to insufficient structural strength, and extending its service life. It also avoids the loosening problems that may occur with spliced ​​structures, ensuring the structural stability of the shock absorber 21 under long-term vibration environments and providing a reliable foundation for subsequent shock absorption.

[0035] Example 7: This embodiment provides a compressor bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0036] Top cover 23 includes: The second annular planar portion 231 has a second through hole formed in the center for the rod portion of the screw to pass through, and the nut 242 axially abuts against the top of the second annular planar portion 231; The second arc-shaped protrusion 232 has an upward bulging structure and is connected to the outer periphery of the second annular planar portion 231. The outer periphery of the second arc-shaped protrusion 232 extends downward in a conical ring shape. The buffer 22 is filled radially and axially between the top cover 23 and the shock absorber 21.

[0037] In this embodiment, the top cover 23 is composed of a second annular planar portion 231 and a second arc-shaped protrusion 232; the second annular planar portion 231 is horizontally arranged and has a second through hole in the center; the second arc-shaped protrusion 232 has an upwardly raised arc-shaped structure, which can enhance its own structural strength and shock absorption effect, and the bottom outer periphery is connected to the outer periphery of the second annular planar portion 231, and the outer periphery extends downward to form a conical ring-shaped structure; the bottom of the nut 242 axially abuts against the top of the second annular planar portion 231; the buffer 22 fills the area between the top cover 23 and the shock absorber 21, and simultaneously achieves radial and axial filling coverage; the inner wall of the conical ring-shaped structure of the top cover 23 is in contact with the outer peripheral surface of the buffer 22. The bidirectional filling design of the buffer 22, combined with the radial limiting of the conical ring plate structure, enables the buffer 22 to efficiently absorb axial and radial vibrations, resulting in higher vibration transmission attenuation efficiency. The radial limiting of the conical ring plate structure prevents the buffer 22 from shifting or falling off under long-term vibration, thus extending the service life of the buffer 22.

[0038] Example 8: This embodiment provides a compressor bracket, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0039] The second annular flat portion 231 and the second arc-shaped protrusion 232 are integrally formed structures.

[0040] In this embodiment, the second annular flat portion 231 and the second arc-shaped protrusion 232 of the top cover 23 are manufactured using an integral molding process, forming a seamless integrated structure. The conical annular plate structure is seamlessly connected to the second arc-shaped protrusion 232. This integrated structure eliminates weak points in the splicing of the top cover 23, allowing it to withstand the vibration and impact of the compressor during operation and preventing deformation or damage to the top cover 23 due to insufficient structural strength. The integrated connection between the conical annular plate structure and the second arc-shaped protrusion 232 ensures stable radial limiting effect on the buffer 22, preventing limiting failure due to loose splicing and guaranteeing the shock absorption effect.

[0042] The buffer 22 is made of rubber.

[0043] In this embodiment, the buffer 22 is made of rubber. Its overall structure is compatible with the assembly gap between the shock absorber 21 and the top cover 23, as well as the buffer gap between the bolt 241 and the first arc-shaped protrusion 212, enabling tight filling. The high elasticity and damping properties of rubber can effectively absorb vibration energy, attenuate vibration transmission, and significantly reduce the noise generated during compressor operation. It also has good wear resistance, can withstand long-term vibration and friction, extend the service life of the buffer 22, and reduce the frequency of replacement. Furthermore, it has a certain degree of flexibility, which can adapt to the filling requirements of different gap sizes, and can better fit the surface of each contact component, improving the stability of the shock absorption effect.
