Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, and more specifically, to a vibration damping device and an air source heat pump. Background Technology

[0002] During operation, air source heat pumps generate significant noise pollution due to mechanical vibration from their internal components such as fans, compressors, and water pumps. This not only directly impacts the user experience but can also lead to serious equipment malfunctions. Under continuous vibration, refrigerant piping systems may break, causing refrigerant leaks. Simultaneously, water pipe seals may fail due to vibration, resulting in water leaks.

[0003] Currently, air source heat pumps commonly use vibration damping pads as the main vibration reduction measure. However, existing vibration damping pads have obvious technical defects: First, their vibration reduction effect is poor, and during long-term use, the vibration damping pads are prone to material fatigue, resulting in a significant decrease in elastic performance; second, under extreme climatic conditions (such as high temperature, low temperature or humid environment), the vibration damping pads are prone to aging and failure, and cannot effectively cope with complex vibration conditions. Utility Model Content

[0004] The purpose of this invention is to provide a vibration damping device and an air source heat pump, which has good vibration damping effect, is not prone to aging or failure, can effectively cope with complex vibration conditions, and reduce noise generation.

[0005] The embodiments of this utility model are implemented as follows:

[0006] In a first aspect, this utility model provides a vibration damping device, comprising:

[0007] Vibration damping block, wherein the vibration damping block has an installation groove; and

[0008] An elastic damping structure is provided, a portion of which is disposed within the mounting groove, and another portion of which protrudes from the mounting groove and is used to connect with the base of the air source heat pump.

[0009] In an optional embodiment, the elastic damping structure includes a damping base, a damping column, and an elastic element. The damping base is disposed within the mounting groove. The damping column is disposed on the damping base, and a portion of the damping column extends out of the mounting groove and is used to connect with the base of the air source heat pump. The elastic element is sleeved on the damping column, and one end of the elastic element abuts against the damping base, while the other end protrudes from the mounting groove.

[0010] In an optional embodiment, the elastic damping structure further includes a cover sleeve fitted over the elastic member and located on the side of the elastic member away from the damping base, the cover sleeve being used to abut against the base of the air source heat pump.

[0011] In an optional embodiment, the cover includes a cover body and an annular sleeve portion. The cover body abuts against the end of the elastic member away from the damping base. The annular sleeve portion is disposed around the periphery of the cover body and sleeved on the elastic member. At least a portion of the annular sleeve portion abuts against the inner sidewall of the mounting groove and is spaced apart from the damping base.

[0012] In an optional embodiment, the elastic damping structure further includes a gasket disposed between the cover and the elastic member, and simultaneously abutting against both the cover and the elastic member.

[0013] In an optional embodiment, the mounting groove is a through groove, the damping base is located at the bottom of the mounting groove, and the bottom surface of the damping base is on the same horizontal line as the bottom surface of the vibration damping block.

[0014] In an optional embodiment, the bottom of the vibration damping block is provided with a first fixing groove and a second fixing groove that are spaced apart, and both the first fixing groove and the second fixing groove are in communication with the mounting groove.

[0015] The damping base is provided with a first fixing part and a second fixing part on opposite sides, the first fixing part is disposed in the first fixing groove, and the second fixing part is disposed in the second fixing groove.

[0016] In an optional embodiment, the bottom wall of the first fixing groove has a first through hole, and the first fixing part has a second through hole, the first through hole communicating with the second through hole; and / or,

[0017] The bottom wall of the second fixing groove is provided with a third through hole, and the second fixing part is provided with a fourth through hole, and the third through hole and the fourth through hole are connected.

[0018] In an optional embodiment, the elastic element is a spring; and / or,

[0019] The damping rod is a screw.

[0020] Secondly, this utility model provides an air-source heat pump, including the vibration damping device described in any of the foregoing embodiments.

[0021] The beneficial effects of this utility model embodiment include:

[0022] The vibration damping device includes a damping block and an elastic damping structure. The damping block has a mounting groove, and a portion of the elastic damping structure is housed within this groove. Another portion of the elastic damping structure protrudes from the groove and connects to the base of the air source heat pump. As easily understood, the height of the elastic damping structure is greater than the height of the damping block; that is, the contact surface between the elastic damping structure and the air source heat pump base is higher than the contact surface of the damping block, allowing the base of the air source heat pump to directly bear the force of the elastic damping structure. When the unit equipment inside the air source heat pump is running, the elastic damping structure absorbs most of the vibration energy. As the elastic damping structure deforms and its height decreases, the damping block contacts the base of the air source heat pump and performs its damping function, achieving secondary absorption of excess vibration energy, thereby improving the vibration damping effect. Furthermore, this elastic damping structure is not prone to aging or failure, effectively coping with complex vibration conditions, reducing noise generation, and thus improving the reliability, stability, and service life of the air source heat pump.

[0023] Air source heat pumps include vibration damping devices, which have all the beneficial effects of such devices. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] As described in the background section, air source heat pumps commonly use vibration damping pads as the primary vibration reduction measure. However, existing vibration damping pads have significant technical defects: First, their vibration reduction effect is poor, and during long-term use, the vibration damping pads are prone to material fatigue, leading to a significant decrease in elastic performance; second, under extreme climatic conditions (such as high temperature, low temperature, or humid environments), the vibration damping pads are prone to aging and failure, and cannot effectively cope with complex vibration conditions.

[0037] Based on this, please refer to Figures 1-4 This utility model provides a vibration damping device 100 and an air source heat pump, which can effectively improve the aforementioned technical problems. It has good vibration damping effect, is not prone to aging or failure, and can effectively cope with complex vibration conditions, reducing noise generation. The vibration damping device 100 and the air source heat pump will be described in detail below.

[0038] This embodiment provides an air source heat pump, which includes a heat pump body (not shown) and a vibration damping device 100. The vibration damping device 100 is connected and fixed to the base of the heat pump body, which can play a role in vibration damping and buffering for the operation of the heat pump body and reduce the noise generated during operation.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of the vibration damping device 100 provided in this embodiment from a first-view perspective. Figure 2 This is a structural schematic diagram of the vibration damping device 100 provided in this embodiment from a second perspective. (Combined with...) Figure 1 and Figure 2 The vibration damping device 100 includes a vibration damping block 10 and an elastic damping structure 20. The elastic damping structure 20 is disposed on the vibration damping block 10 and is used to connect with the base of the heat pump body.

[0040] Further, please refer to Figure 3 , Figure 3 for Figure 2 A sectional view along the AA direction, combined with Figures 1-3The vibration damping block 10 has a mounting groove 11. A part of the elastic damping structure 20 is disposed in the mounting groove 11, and another part of the elastic damping structure 20 protrudes from the mounting groove 11 and is used to connect with the base of the air source heat pump.

[0041] As is easily understood, the height of the elastic damping structure 20 is greater than the height of the vibration damping block 10. That is, the contact surface between the elastic damping structure 20 and the air source heat pump base is higher than the contact surface of the vibration damping block, allowing the air source heat pump base to directly bear the force of the elastic damping structure 20. When the unit equipment inside the air source heat pump is running, the elastic damping structure 20 can absorb most of the vibration energy of the unit equipment. After the elastic damping structure 20 undergoes elastic deformation and its height decreases, the vibration damping block 10 contacts the air source heat pump base and plays a damping role, achieving secondary absorption of excess vibration energy, thereby improving the damping effect. Furthermore, the elastic damping structure 20 is not prone to aging or failure, effectively coping with complex vibration conditions, reducing noise generation, and thus improving the reliability, stability, and service life of the air source heat pump.

[0042] It should be noted that in this embodiment, the damping block 10 is specifically a rubber block. Of course, in other embodiments, the damping block 10 can also be other elastic damping structures.

[0043] Combination Figure 3 Specifically, the elastic damping structure 20 includes a damping base 21, a damping column 22, and an elastic element 23. The damping base 21 is disposed in the mounting groove 11; the damping column 22 is disposed in the damping base 21, and a part of the damping column 22 extends out of the mounting groove 11 and is used to connect with the base of the air source heat pump; the elastic element 23 is sleeved on the damping column 22, and one end of the elastic element 23 abuts against the damping base 21, and the other end protrudes out of the mounting groove 11.

[0044] In other words, the damping column 22 can connect and fix the vibration damping device 100 to the base of the air source heat pump, while the elastic element 23 can abut against the base of the air source heat pump, thereby absorbing the vibration energy generated during the operation of the unit.

[0045] It should be noted that in this embodiment, the elastic element 23 is specifically a spring. Of course, in other embodiments, the elastic element 23 can also be a rubber sleeve or a spring sheet, or other elastic structures. In addition, in this embodiment, the damping column 22 is specifically a screw. The screw can be easily threadedly connected to the damping base 21 and the base of the air source heat pump, resulting in high stability. Of course, in other embodiments, the damping column 22 can also be a screw, bolt, or pin, or other fastening structures.

[0046] To protect the elastic element 23 and increase the contact area with the base of the air source heat pump to improve vibration damping, in this embodiment, the elastic damping structure 20 further includes a cover 24. The cover 24 is fitted onto the elastic element 23 and located on the side of the elastic element 23 away from the damping base 21. The cover 24 is used to abut against the base of the air source heat pump. By providing the cover 24, the base of the air source heat pump can also be protected to a certain extent, reducing wear.

[0047] Specifically, the cover 24 includes a cover body 241 and an annular sleeve portion 242. The cover body 241 abuts against the end of the elastic member 23 away from the damping base 21. The annular sleeve portion 242 is disposed around the periphery of the cover body 241 and is fitted onto the elastic member 23. At least a portion of the annular sleeve portion 242 abuts against the inner wall of the mounting groove 11 and is spaced apart from the damping base 21. On one hand, by fitting the annular sleeve portion 242 onto the elastic member 23, the elastic member 23 can be protected, allowing it to better perform its elastic buffering function, thereby improving the vibration reduction effect. On the other hand, by abutting the annular sleeve portion 242 against the inner wall of the mounting groove 11, the stability of the cover 24 during its up-and-down movement under the action of the elastic member 23 can be improved, which also improves the vibration reduction effect.

[0048] In order to reduce wear on the cover 24, further protect the elastic element 23 and the cover 24, and improve stability during the buffer movement, in this embodiment, the elastic damping structure 20 also includes a gasket 25, which is disposed between the cover 24 and the elastic element 23 and simultaneously abuts against both the cover 24 and the elastic element 23.

[0049] Please refer to Figure 4 , Figure 4 This is a cross-sectional view of the vibration damping block 10 provided in this embodiment, combined with... Figure 3 and Figure 4 The mounting groove 11 is a through groove, and the damping base 21 is located at the bottom of the mounting groove 11, with the bottom surface of the damping base 21 and the bottom surface of the vibration damping block 10 on the same horizontal line. That is to say, the bottom surface of the damping base 21 is flush with the bottom surface of the vibration damping block 10. When the vibration damping device 100 is installed on the ground or other mounting platform, the damping base 21 and the vibration damping block 10 can simultaneously contact the ground or mounting platform, thereby improving the installation stability of the vibration damping device 100 and ensuring the subsequent vibration damping effect.

[0050] Furthermore, the bottom of the damping block 10 is provided with a first fixing groove 12 and a second fixing groove 13 spaced apart, both of which are connected to the mounting groove 11. The damping base 21 has a first fixing part 211 and a second fixing part 212 on opposite sides, the first fixing part 211 being disposed in the first fixing groove 12 and the second fixing part 212 being disposed in the second fixing groove 13.

[0051] By cooperating with the first fixing part 211 and the first fixing groove 12, and with the second fixing part 212 and the second fixing groove 13, the installation stability of the damping base 21 can be improved, thereby improving the connection stability between the elastic damping structure 20 and the base of the air source heat pump, and reducing the swaying of the damping base 21 during subsequent vibration of the unit.

[0052] Please continue to combine Figure 3 and Figure 4 In order to facilitate the installation of the vibration damping device 100 as a whole on the ground or other installation platform, so as to improve the overall stability and ensure the subsequent vibration damping effect, in this embodiment, the bottom wall of the first fixing groove 12 is provided with a first through hole 14, and the first fixing part 211 is provided with a second through hole 2111, and the first through hole 14 and the second through hole 2111 are connected.

[0053] Similarly, in order to facilitate the overall installation of the vibration damping device 100, a third through hole 15 is provided on the bottom wall of the second fixing groove 13, and a fourth through hole 2121 is provided on the second fixing part 212. The third through hole 15 and the fourth through hole 2121 are connected.

[0054] In summary, the embodiments of this utility model provide a vibration damping device 100 and an air source heat pump. The vibration damping device 100 includes a vibration damping block 10 and an elastic damping structure 20. The vibration damping block 10 has a mounting groove 11. A portion of the elastic damping structure 20 is disposed within the mounting groove 11, and another portion of the elastic damping structure 20 protrudes from the mounting groove 11 and is used to connect with the base of the air source heat pump. It is easily understood that the height of the elastic damping structure 20 is greater than the height of the vibration damping block 10; that is, the contact surface between the elastic damping structure 20 and the base of the air source heat pump is higher than the contact surface of the vibration damping block, allowing the base of the air source heat pump to directly bear the force of the elastic damping structure 20.

[0055] When the unit equipment inside the air source heat pump is running, the elastic damping structure 20 can absorb most of the vibration energy of the unit equipment. After the elastic damping structure 20 undergoes elastic deformation and its height decreases, the vibration damping block 10 contacts the base of the air source heat pump and plays a vibration damping role, realizing secondary absorption of excess vibration energy, thereby improving the vibration damping effect. Moreover, the elastic damping structure 20 is not prone to aging or failure, and can effectively cope with complex vibration conditions, reducing noise generation, thereby improving the reliability, stability and service life of the air source heat pump.

[0056] The air source heat pump includes a vibration damping device 100, which has all the functions and benefits of the vibration damping device 100.
