[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described features. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0041] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0042] Example 1

[0043] In the air conditioner, the compressor is fixed on the chassis 2, and the bolt column erected on the chassis 2 passes through the compressor foot and is locked by a nut. Since the compressor generates vibration during operation, the vibration is transmitted to the chassis 2 and the frame structure of the bracket to form vibration transmission, which stimulates the chassis 2 and the frame structure of the bracket to resonate, thereby generating noise; among them, short-term noise affects the user experience, while long-term noise affects the stability of the frame structure.

[0044] The existing solution is to add a vibration reduction structure between the chassis 2 and the compressor to reduce vibration, so as to reduce the vibration generated when the compressor is running, thereby improving noise performance and increasing the reliability of product operation. However, the existing vibration reduction structure will be damaged or reduced in elasticity due to assembly impact force, compression, etc., which greatly limits its own vibration reduction effect.

[0045] In order to solve the above problems, refer to the attached Figure 1-3 , the utility model proposes a vibration reduction structure, including a vibration reduction base 10 and a support base 20;

[0046] The bottom wall of the vibration-damping base 10 is provided with a plurality of accommodating cavities 101 along the circumferential direction and inwardly, which is equivalent to that the plurality of accommodating cavities 101 can enclose a circle on the bottom wall of the vibration-damping base 10, and a magnetic body 102 is further provided between any two adjacent accommodating cavities 101, and the polarities of the opposite surfaces of any two adjacent magnetic bodies 102 are opposite;

[0047] The support base 20 is provided with a plurality of support members 201 corresponding to the accommodating cavity 101, each of the support members 201 can be matched and embedded in the corresponding accommodating cavity 101, and each of the support members 201 is provided with a plurality of through holes 202 along its axial direction;

[0048] All the magnetic bodies 102 form a closed magnetic field along the circumference of the vibration reduction base 10 , and each through hole 202 forms a closed annular boundary, and the closed annular boundary can cut the closed magnetic field to form a magnetic vibration reduction system.

[0049] It should be noted that the vibration reduction structure in this embodiment is illustrated by being installed on the foot of a device that can generate vibration, and the device is preferably a compressor; the number of support members 201 in this embodiment is illustrated by 16.

[0050] In this way, when the device vibrates at a high frequency and high intensity and transmits it to the support base 20, the support base 20 will also vibrate, thereby causing the closed annular boundary formed by the through holes 202 on each support member 201 to cut the closed magnetic field formed by all the magnetic bodies 102 to form a magnetic vibration reduction system. The magnetic vibration reduction system can convert the vibration energy generated by the device into a resistive heat effect in the support member 201 and consume it, thereby enhancing the absorption of vibration energy and improving the vibration reduction effect. In this way, even if the vibration reduction base 10 is damaged or reduced in elasticity due to assembly impact force, compression, etc., thereby greatly limiting its own vibration reduction effect, it will not affect the vibration reduction effect of the magnetic vibration reduction system formed by the entire vibration reduction structure.

[0051] It should be noted that the closed annular boundaries formed by the through holes 202 on each support member 201 have a cutting effect with the closed magnetic field formed by all the magnetic bodies 102, which is equivalent to electromagnetic induction. The electromagnetic induction effect can convert the vibration energy of the equipment into a resistive heat effect in the support member 201 and consume it.

[0052] When the electromagnetic induction can convert the vibration energy of the equipment into the resistive thermal effect in the support 201 and consume it, the temperature of the support 201 itself will rise, resulting in a decrease in its own stiffness (because of the influence of heat energy, the higher the temperature, the weaker the connection between metal atoms, and the macroscopic structural stiffness decreases), that is, the support 201 will be softer than before the temperature rises; and the vibration damping base 10 is made of rubber, which has a certain elasticity. When the support base 20 is embedded in the vibration damping base 10, the support base 20 can transfer the vibration energy to the vibration damping base 10 along the extension direction of the support 201, and the vibration damping base 10 then absorbs the vibration energy in the same direction through the good elasticity of rubber to achieve a vibration damping effect, and the support base 20 can also enhance the bearing capacity and stability of the vibration damping base 10; and when the support 201 located in the vibration damping base 10 causes its own stiffness to decrease due to electromagnetic induction, it can cooperate with the vibration damping base 10 to achieve a better vibration damping effect, that is, the vibration damping structure can achieve a better vibration damping effect, while reducing the low-frequency noise generated by the equipment.

[0053] It should be noted that the shape of the magnetic body 102 is preferably a rectangular parallelepiped, and the material of the rectangular parallelepiped magnetic body 102 is preferably a magnetic rubber body. The magnetic rubber body is a special composite material that combines the properties of magnetic and elastic materials. Therefore, the magnetic rubber body is usually composed of a rubber matrix and NdFeB powder embedded therein. In order to ensure that the magnetic rubber body can form a magnetization distribution with N poles and S poles, when the rubber matrix and NdFeB powder are mixed together, the NdFeB powder is ensured to be evenly dispersed, and then before the mixture is solidified, it is placed in an external magnetic field with a known direction and strong enough so that the NdFeB powder can be arranged in the direction of the magnetic field; then the mixture is solidified under the action of the magnetic field, and after the solidification is completed, the NdFeB powder will maintain its arrangement in the magnetic field, thereby forming a magnetic rubber body with a specific magnetic pole distribution; and when the external magnetic field is withdrawn, the NdFeB powder still has sufficient remanence to ensure that the magnetic rubber body can still retain a certain magnetism and generate a magnetic field after the external magnetic field is withdrawn.

[0054] Of course, in other embodiments, the shape of the magnetic body 102 is preferably a rectangular parallelepiped, and the material of the magnetic body 102 is preferably a neodymium iron boron magnet.

[0055] Each through hole 202 forms a closed annular boundary, which means:

[0056] Since the through hole 202 is located at the edge of the support 201 and has a large curvature, according to the principle of charge distribution on the surface of the conductor, the charges naturally tend to be densely distributed in such high curvature areas. At the same time, considering the performance of the skin effect when the alternating current passes through the conductor (equivalent to the induced current generated when the support 201 cuts the closed magnetic field), this trend of charge distribution is still significant even in the case of direct current or low frequency. Therefore, the through hole 202 not only serves as a physical penetration point, but also naturally forms a closed annular boundary, and the distribution pattern of the charges on it shows a configuration similar to a current loop.

[0057] Among them, refer to the attached Figure 1 The support base 20 is evenly provided with a plurality of support members 201 in the circumferential direction, and each of the support members 201 is evenly provided with a plurality of through holes 202 along the axial direction thereof.

[0058] In this way, the support base 20 can better support the vibration reduction base 10 to improve the vibration reduction effect of the vibration reduction structure; and the through holes 202 are evenly arranged on the support member 201, which can ensure that the closed annular boundary formed by the through holes 202 and its surrounding areas can better cut the closed magnetic field to form a more stable and better vibration reduction system.

[0059] Among them, refer to the attached Figure 1 , the support members 201 are all arranged vertically, and the accommodating cavities 101 are correspondingly arranged vertically.

[0060] In this way, when the support base 20 is embedded in the vibration-damping base 10 , the axial or longitudinal impact resistance of the vibration-damping base 10 can be enhanced.

[0061] In order to ensure that the closed annular boundary formed by the through hole 202 and its surrounding area can better cut the closed magnetic field to form a more stable magnetic vibration reduction system with better vibration reduction effect, refer to the attached Figure 1 and 3 , the shape of the support member 201 is cylindrical, the shape of the through hole 202 is preferably circular, and the diameter of the through hole 202 is d=0.2D-0.3D;

[0062] Wherein, D is the diameter of the support member 201 .

[0063] In order to ensure that the through hole 202 on the support member 201 can perform cutting in a closed magnetic field, the support base 20 is made of a magnetic induction material. The magnetic induction material in this embodiment is copper as an example. Of course, the magnetic induction material can also be other magnetic induction materials such as iron and nickel that can exhibit a magnetic induction effect in a magnetic field.

[0064] In order to ensure that the vibration-damping base 10 has elasticity to achieve vibration reduction, the vibration-damping base 10 is made of any one of rubber, silica gel, polyethylene foam and polyurethane foam. In this embodiment, the vibration-damping base 10 is made of rubber as an example.

[0065] Among them, refer to the attached Figure 1 A first mounting through hole 103 is axially provided in the middle of the vibration-damping base 10, and the accommodating cavity 101 and the magnetic body 102 are both arranged around the first mounting through hole 103;

[0066] A second mounting through hole 203 is also provided in the middle of the support base 20 corresponding to the first mounting through hole 103 , and the support member 201 is disposed around the second mounting through hole 203 .

[0067] This makes it convenient for bolts or other fasteners to pass through the first mounting through hole 103 and the second mounting through hole 203 and then be fixed on the machine foot of the device, so as to reduce the vibration generated when the device is running, thereby improving the noise performance.

[0068] In order to better install the vibration reduction base 10 on the machine foot of the equipment, refer to the attached Figure 1 and 4 The top of the vibration-damping base 10 is recessed inward around the first mounting through hole 103 to form a mounting groove 104 .

[0069] In this way, the mounting groove 104 can be correspondingly inserted into the foot of the device, and then fixed to the foot of the device by passing bolts or other fasteners through the first mounting through hole 103 and the second mounting through hole 203.

[0070] Example 2

[0071] See attached Figure 5-6 The utility model also proposes a compressor, which includes the vibration reduction structure described above.

[0072] The compressor is fixed on the chassis 2, and a vibration reduction structure is installed on the compressor foot, specifically:

[0073] The mounting groove 104 of the vibration-damping base 10 can be inserted into the compressor foot accordingly, and then the bolts pass through the chassis 2, the second mounting hole 203 of the support base 20 and the first mounting hole 103 of the vibration-damping base 10 in sequence, and then pass through the compressor foot, and finally fixed with corresponding nuts.

[0074] In this way, when the compressor vibrates at a high frequency and high intensity and transmits it to the support base 20, the support base 20 will also vibrate, thereby causing the closed annular boundary formed by the through holes 202 on each support member 201 to cut the closed magnetic field formed by all the magnetic bodies 102 to form a magnetic vibration reduction system. The magnetic vibration reduction system can convert the vibration energy generated by the compressor into a resistive heat effect in the support member 201 and consume it, thereby enhancing the absorption of vibration energy and improving the vibration reduction effect. In this way, even if the vibration reduction base 10 is damaged or reduced in elasticity due to assembly impact force, compression, etc., thereby greatly limiting its own vibration reduction effect, it will not affect the vibration reduction effect of the magnetic vibration reduction system formed by the entire vibration reduction structure.

[0075] It should be noted that the closed annular boundaries formed by the through holes 202 on each support member 201 have a cutting effect on the closed magnetic field formed by all the magnetic bodies 102, which is equivalent to electromagnetic induction. The electromagnetic induction effect can convert the vibration energy of the compressor into the resistive heat effect in the support member 201 and consume it.

[0076] When the electromagnetic induction can convert the vibration energy of the compressor into the resistive thermal effect in the support member 201 and consume it, the temperature of the support member 201 itself will rise, resulting in a decrease in its own stiffness (because of the influence of heat energy, the higher the temperature, the weaker the connection between metal atoms, and the macroscopic structural stiffness decreases), that is, the support member 201 is softer than before the temperature rises; and the vibration damping base 10 is made of rubber, which has a certain elasticity. When the support base 20 is embedded in the vibration damping base 10, the support base 20 can transfer the vibration energy to the vibration damping base 10 along the extension direction of the support member 201, and the vibration damping base 10 then absorbs the vibration energy in the same direction through the good elasticity of rubber to achieve a vibration damping effect, and the support base 20 can also enhance the bearing capacity and stability of the vibration damping base 10; and when the support member 201 located in the vibration damping base 10 causes its own stiffness to decrease due to the electromagnetic induction effect, it can cooperate with the vibration damping base 10 to achieve a better vibration damping effect, that is, the vibration damping structure can achieve a better vibration damping effect, while reducing the low-frequency noise generated by the compressor.

[0077] The use principle of the vibration reduction structure of the utility model:

[0078] First, the vibration-damping base 10 is inserted into the machine foot of the compressor through the mounting groove 104, and then bolts or other fasteners are passed through the chassis 2, the second mounting through hole 203 and the first mounting through hole 103 in sequence and then fixed to the machine foot of the compressor. In this way, when the compressor vibrates, the vibration-damping base 10 made of rubber and the supporting base 20 made of magnetic induction metal material cooperate with each other to form a composite vibration reduction by relying on the elasticity of the vibration-damping base 10 and the structural strength of the supporting base 20; and then the closed annular boundaries formed by the through holes 202 on each support member 201 are cut with the closed magnetic field formed by all the magnetic bodies 102 to form a magnetic vibration reduction system. In this way, through the cooperation of the composite vibration reduction and the magnetic vibration reduction system, the vibration reduction effect of the vibration reduction structure is further improved, and the low-frequency noise generated by the compressor is further reduced.

[0079] Example 3

[0080] See attached Figure 5-6 The utility model also provides an air conditioner, which includes a chassis 2 and a compressor, and the compressor includes the vibration reduction structure described above.

[0081] The compressor is fixed on the chassis 2, and a vibration reduction structure is installed on the compressor foot, specifically:

[0082] The mounting groove 104 of the vibration-damping base 10 can be inserted into the compressor foot accordingly, and then the bolts pass through the chassis 2, the second mounting hole 203 of the support base 20 and the first mounting hole 103 of the vibration-damping base 10 in sequence, and then pass through the compressor foot, and finally fixed with corresponding nuts.

[0083] In this way, when the compressor vibrates at a high frequency and high intensity and transmits it to the support base 20, the support base 20 will also vibrate, thereby causing the closed annular boundary formed by the through holes 202 on each support member 201 to cut the closed magnetic field formed by all the magnetic bodies 102 to form a magnetic vibration reduction system. The magnetic vibration reduction system can convert the vibration energy generated by the compressor into a resistive heat effect in the support member 201 and consume it, thereby enhancing the absorption of vibration energy and improving the vibration reduction effect. In this way, even if the vibration reduction base 10 is damaged or reduced in elasticity due to assembly impact force, compression, etc., thereby greatly limiting its own vibration reduction effect, it will not affect the vibration reduction effect of the magnetic vibration reduction system formed by the entire vibration reduction structure.

[0084] It should be noted that the closed annular boundaries formed by the through holes 202 on each support member 201 have a cutting effect on the closed magnetic field formed by all the magnetic bodies 102, which is equivalent to electromagnetic induction. The electromagnetic induction effect can convert the vibration energy of the compressor into the resistive heat effect in the support member 201 and consume it.

[0085] When the electromagnetic induction can convert the vibration energy of the compressor into the resistive thermal effect in the support member 201 and consume it, the temperature of the support member 201 itself will rise, resulting in a decrease in its own stiffness (because of the influence of heat energy, the higher the temperature, the weaker the connection between metal atoms, and the macroscopic structural stiffness decreases), that is, the support member 201 will be softer than before the temperature rises; and the vibration damping base 10 is made of rubber, which has a certain elasticity. When the support base 20 is embedded in the vibration damping base 10, the support base 20 can transfer the vibration energy to the vibration damping base 10 along the extension direction of the support member 201, and the vibration damping base 10 then absorbs the vibration energy in the same direction through the good elasticity of rubber to achieve a vibration damping effect, and the support base 20 can also enhance the bearing capacity and stability of the vibration damping base 10; and when the support member 201 located in the vibration damping base 10 causes its own stiffness to decrease due to the electromagnetic induction effect, it can cooperate with the vibration damping base 10 to achieve a better vibration damping effect, that is, the vibration damping structure can achieve a better vibration damping effect, while reducing the low-frequency noise generated by the compressor.

[0086] Example 4

[0087] See attached Figure 7 The utility model also provides a fan, which includes a motor 1, and the motor 1 includes the vibration reduction structure described above.

[0088] Among them, a vibration reduction structure is installed on the machine foot of the motor 1, specifically:

[0089] The mounting groove 104 of the vibration-damping base 10 can be inserted into the machine foot of the motor 1 accordingly, and then the bolts pass through the second mounting through hole 203 of the support base 20 and the first mounting through hole 103 of the vibration-damping base 10 in sequence, and then pass through the machine foot of the motor 1, and finally fixed with corresponding nuts.

[0090] It should be noted that the motor 1 in the fan is prone to vibration during operation due to the circumferential imbalance of the fan blades, and the vibration generated by the motor 1 at this time is circumferential vibration; therefore, in order to ensure that the circumferential vibration generated by the motor 1 in the fan can be better converted into axial vibration, so as to control the vibration reduction direction and effectively ensure the reliability of the circumferential movement of the fan, refer to the attached Figure 8 , the support members 201 are all arranged in a spiral shape, and the accommodating chambers 101 are correspondingly arranged in a spiral shape.

[0091] The spirally arranged support members 201 can convert the circumferential vibration generated by the motor 1 in the fan into axial vibration to control the vibration reduction direction, effectively ensure the reliability of the circumferential movement of the fan, and reduce the low-frequency noise generated by the motor 1.

[0092] In this way, when the motor 1 vibrates at a high frequency and high intensity and transmits it to the support base 20, the support base 20 will also vibrate, so that the closed annular boundary formed by the through holes 202 on each support member 201 and the closed magnetic field formed by all the magnetic bodies 102 are cut to form a magnetic vibration reduction system. The magnetic vibration reduction system can convert the vibration energy generated by the motor 1 into a resistive heat effect in the support member 201 and consume it, thereby enhancing the absorption of vibration energy and improving the vibration reduction effect. In this way, even if the vibration reduction base 10 is damaged or reduced in elasticity due to assembly impact force, compression, etc., thereby greatly limiting its own vibration reduction effect, it will not affect the vibration reduction effect of the magnetic vibration reduction system composed of the entire vibration reduction structure.

[0093] It should be noted that the closed annular boundaries formed by the through holes 202 on each support member 201 have a cutting effect on the closed magnetic field formed by all the magnetic bodies 102, which is equivalent to electromagnetic induction. The electromagnetic induction effect can convert the vibration energy of the motor 1 into a resistive heat effect in the support member 201 and consume it.

[0094] When the electromagnetic induction can convert the vibration energy of the motor 1 into the resistance heat effect in the support 201 and consume it, the temperature of the support 201 itself will rise, resulting in a decrease in its own stiffness (because of the influence of heat energy, the higher the temperature, the weaker the connection between metal atoms, and the macroscopic structural stiffness decreases), that is, the support 201 will be softer than before the temperature rises; and the vibration reduction base 10 is made of rubber, which has a certain elasticity. When the support base 20 is embedded in the vibration reduction base 10, the spirally arranged support 201 can reduce the vibration of the fan. The circumferential vibration generated by the motor 1 is converted into axial vibration, and then transmitted to the vibration-damping base 10. The vibration-damping base 10 then absorbs the vibration energy in the same direction through the good elasticity of rubber to achieve a vibration-damping effect, and the support base 20 can also enhance the bearing capacity and stability of the vibration-damping base 10; and when the support member 201 located in the vibration-damping base 10 has its own stiffness reduced due to electromagnetic induction, it can cooperate with the vibration-damping base 10 to achieve a better vibration-damping effect, that is, the vibration-damping structure can achieve a better vibration-damping effect, while reducing the low-frequency noise generated by the motor 1.

[0095] In order to achieve a better vibration reduction effect for the motor 1, refer to the attached Figure 7 A vibration reduction mechanism is provided at the top and bottom of the base foot of the motor 1, and the tops of the two vibration reduction mechanisms are arranged opposite to each other and clamp the base foot.

[0096] Specifically, the mounting grooves 104 of the two vibration-damping bases 10 are respectively inserted into the base of the motor 1 from the top and bottom of the base of the motor 1, and then bolts or other fasteners are used to clamp the base of the motor 1 with the two vibration-damping bases 10, so that the motor 1 can achieve a better vibration reduction effect.
