Description

Technical Field

[0001] This application relates to the technical field of fan fixing structures, and in particular to a vibration damping and fixing structure for a fan. Background Art

[0002] In the design of traditional high-volume centrifugal fans, a significant technical challenge lies in the vibration problems caused by the centrifugal force and eccentric force generated during fan operation. These vibrations are not only directly transmitted to the structural components of the fan and even the entire unit, resulting in obvious shaking of the fuselage, but also often accompanied by resonance noise, greatly affecting the user experience of consumers and reducing the overall satisfaction of the product. In addition, these vibrations may also have an adverse impact on the stability and service life of the fan, increasing the risk of equipment failure.

[0003] Traditional solutions to vibration problems often focus on using a rigid fixing method to firmly install the fan on the fixing bracket in order to reduce the transmission of vibrations. However, although this fixing method restricts the spread of vibrations to a certain extent, it also brings the disadvantage of inconvenient disassembly and assembly. During the later maintenance stage, a large amount of time and manpower are required to disassemble and reassemble the fan, which not only increases the maintenance cost but also may lead to low maintenance efficiency and great difficulty. Utility Model Content

[0004] The purpose of the embodiments of this application is to provide a vibration damping and fixing structure for a fan. By sleeving a flexible washer with a support member on the fan structure, the transmission of fan vibrations is reduced while ensuring the installation strength, and the equipment operation noise is lowered.

[0005] To achieve the above object, this application adopts the following technical solutions:

[0006] On the one hand, a vibration damping and fixing structure for a fan is provided, including: a fan, with an embedding plate provided at the edge of its air outlet;

[0007] A flexible washer, with a support member provided inside, and an embedding groove corresponding to the embedding plate is provided on the flexible washer so that the flexible washer can be pushed along the embedding plate;

[0008] A fixing plate, with an installation groove provided at its bottom, and the embedding plate sleeved with the flexible washer can be pushed into the installation groove along the installation direction. A ventilation opening corresponding to the air outlet is also provided on the fixing plate.

[0009] Further, a limiting strip is provided at the bottom of the fixing plate, and the limiting strip is located at the end of the installation groove.

[0010] Further, a fixing strip is also included, and the fixing strip is detachably installed at the initial end of the installation groove.

[0011] Furthermore, it also includes a fastener, and the initial end of the installation groove has two sides extending outward to form a folded edge, and a first locking hole is formed on the folded edge, and a second locking hole opposite to the first locking hole is formed on the fixing strip, and the fastener passes through the second locking hole and is locked in the first locking hole, or the fastener passes through the first locking hole and is locked in the second locking hole.

[0012] Furthermore, a positioning plate which is positioned and matched with the flexible gasket is provided at the edge of the vent.

[0013] Furthermore, an L-shaped mounting portion is provided at the bottom of the fixing plate, and the mounting groove is defined between the mounting portion and the positioning plate.

[0014] Furthermore, the flexible gasket is U-shaped, and the embedding groove extends from a center line connecting two ends of the flexible gasket along the installation direction.

[0015] Furthermore, the cross section of the support member is U-shaped and is embedded in the flexible gasket.

[0016] Furthermore, the support member is one of a galvanized plate, a stainless steel plate and an aluminum plate.

[0017] Furthermore, the flexible gasket is one of a rubber gasket, a silicone gasket, a polytetrafluoroethylene gasket and a fiber gasket.

[0018] The beneficial effects of the present application are as follows: the structure comprises three major parts: a fan, a flexible gasket and a fixed plate. An embedded plate is specially arranged at the edge of the fan outlet as the key to connecting with the flexible gasket. A support is embedded inside the flexible gasket. Its unique elastic and supportive design can effectively absorb and disperse the vibration energy during the operation of the fan while ensuring the installation strength. The embedded groove on the gasket is precisely matched with the fan embedded plate to ensure a stable and smooth installation. An installation groove is arranged at the bottom of the fixed plate, and the embedded plate with a flexible gasket can be easily pushed into it. At the same time, the vents on the fixed plate ensure that the normal ventilation of the fan is not obstructed. When the fan is running, the synergistic effect of the flexible gasket and the support significantly reduces the amplitude of vibration transmitted to the fixed plate and the entire unit. The elastic deformation of the gasket effectively absorbs the vibration energy, and the support further disperses the vibration through its structural characteristics, thereby greatly reducing the body shaking and resonance noise, and improving the stability and service life of the equipment. In addition, the design of the vibration-damping fixing structure also fully considers the convenience of installation and maintenance. The elastic design of the flexible gasket makes the installation process smoother, and also facilitates the subsequent disassembly and maintenance work, reducing the maintenance cost and difficulty.

[0028] To make the technical problems solved by the present application, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present application will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0029] In the description of the present application, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0030] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0031] As Figures 1 - 7 shown, this embodiment provides a vibration damping and fixing structure for a fan, including: a fan 1, a flexible washer 2 and a fixing plate 3. An embedding plate 102 is arranged at the edge of the air outlet 101 of the fan 1; a support member 4 is arranged inside the flexible washer 2, and an embedding groove 201 corresponding to the embedding plate 102 is formed on the flexible washer 2 so that the flexible washer 2 can be pushed along the embedding plate 102; an installation groove 306 is arranged at the bottom of the fixing plate 3, and the embedding plate 102 sleeved with the flexible washer 2 can be pushed into the installation groove 306 along the installation direction. A ventilation opening 301 corresponding to the air outlet 101 is also formed on the fixing plate 3.

[0032] Based on the above solution, first, an embedding plate 102 is provided at the edge of the air outlet 101 of the fan 1. This embedding plate 102 serves as a key component for connecting with the flexible gasket 2. At the same time, an installation groove 306 is opened at the bottom of the fixing plate 3, and a ventilation opening 301 corresponding to the air outlet 101 of the fan 1 is opened on the fixing plate 3 to ensure the normal ventilation function of the fan 1. The flexible gasket 2 is internally embedded with support members 4. While providing the necessary support force, these support members 4 also absorb and disperse vibration energy through their elastic characteristics. The embedding groove 201 opened on the flexible gasket 2 matches the embedding plate 102 on the fan 1 to ensure that the two can fit closely. The installation process is as follows: Push the embedding plate 102 sleeved with the flexible gasket 2 (including the support members 4) along the edge of the air outlet 101 of the fan 1 into the installation groove 306 of the fixing plate 3. During this process, the elasticity of the flexible gasket 2 makes the installation process smoother, and at the same time, the support members 4 ensure the stability of the installation. When the fan 1 is running, the centrifugal force and eccentric force generated will attempt to be transmitted through the embedding plate 102. However, due to the existence of the flexible gasket 2 and the support members 4, a large amount of this vibration energy is absorbed and dispersed before being transmitted to the fixing plate 3. The elastic deformation of the flexible gasket 2 can absorb part of the vibration energy, while the support members 4 further disperse the vibration through their structural characteristics, thereby significantly reducing the vibration amplitude transmitted to the fixing plate 3 and even the entire unit; in addition, the ventilation opening 301 on the fixing plate 3 ensures that the normal ventilation function of the fan 1 is not affected. At the same time, due to the reduction of vibration transmission, the resonance noise caused by vibration is also greatly reduced, improving the user experience of consumers.

[0033] Generally speaking, through the unique combination of the flexible gasket 2 and the support members 4, the goal of effectively reducing the vibration transmission of the fan 1 and reducing the operating noise of the equipment is achieved while ensuring the installation strength. This innovative design not only improves the overall performance and reliability of the product, but also significantly improves the user experience of consumers and enhances the market competitiveness of the product. At the same time, the elastic design of the flexible gasket 2 makes the installation process smoother, and also facilitates the later disassembly and maintenance work, reducing the maintenance cost and difficulty. Moreover, the entire vibration damping and fixing structure is compact, reasonably designed, does not occupy extra space, and does not affect the normal ventilation function of the fan 1.

[0034] It is worth mentioning that the main reason for setting the support members 4 inside the flexible gasket 2 is the fatigue problem of the flexible material. The support members 4 can provide better shock absorption performance and longer service life. Therefore, the support members 4 are embedded inside the flexible gasket 2 to meet the fatigue of the flexible gasket 2 caused by the long-term vibration of the fan 1 and the strength guarantee of the entire flexible gasket 2, so as to both reduce the vibration of the fan 1 and meet the long-term strength requirements.

[0035] Further, a limiting strip 302 is provided at the bottom of the fixing plate 3, and the limiting strip 302 is located at the end of the installation groove 306. When the embedding plate 102 sleeved with the flexible washer 2 is pushed into the installation groove 306 of the fixing plate 3 along the installation direction, the limiting strip 302 serves as a physical barrier, ensuring that the embedding plate 102 can accurately and firmly reach its predetermined installation position without damaging the installation structure or causing unnecessary vibration transmission due to excessive pushing. At the same time, the presence of the limiting strip 302 also provides additional supporting force, further enhancing the connection strength between the fan 1 and the fixing plate 3, making the entire vibration damping and fixing structure more stable and reliable during the operation of the fan 1.

[0036] Furthermore, a fixing strip 5 is further included. The fixing strip 5 is designed to be detachably installed at the initial end of the installation groove 306. After the embedding plate 102 sleeved with the flexible washer 2 is completely embedded in the installation groove 306, the operator can install the fixing strip 5 at the initial end position of the installation groove 306. At this time, the fixing strip 5 and the limiting strip 302 at the end position jointly form a limiting and fixing effect on the embedding plate 102 on both sides in the installation direction. This double-limiting design not only ensures the stable position of the embedding plate 102 in the installation groove 306, but also further enhances the connection strength between the fan 1 and the fixing plate 3, preventing loosening or displacement caused by vibration or external force. In addition, the detachable nature of the fixing strip 5 also provides convenience for subsequent maintenance and replacement work. When it is necessary to disassemble or replace the fan 1, the operator can easily remove the fixing strip 5, enabling the embedding plate 102 to smoothly exit from the installation groove 306, thus simplifying the maintenance process and improving work efficiency.

[0037] Meanwhile, to further enhance the stability and reliability of the vibration damping and fixing structure of the fan 1, fasteners and the corresponding flanges 304 and locking hole structures are also designed. Specifically, on both sides of the initial end of the installation groove 306, flanges 304 extend outward respectively. The flanges 304 not only increase the structural strength of the installation groove 306 but also provide a stable foundation for the installation of the fasteners. On the flanges 304, first locking holes 305 are opened, and these hole positions precisely correspond to the second locking holes 501 opened on the fixing strip 5, jointly constituting the locking structure of the fasteners. When the embedding plate 102 sleeved with the flexible washer 2 is completely embedded in the installation groove 306, and the fixing strip 5 is placed at the initial end of the installation groove 306 for limit fixing, the operator can use the fasteners for final fixing. The fasteners can pass through the second locking holes 501 on the fixing strip 5 and then be locked in the first locking holes 305 on the flanges 304; alternatively, the fasteners can also first pass through the first locking holes 305 on the flanges 304 and then be locked in the second locking holes 501 of the fixing strip 5. In either way, it can ensure that the fasteners firmly connect the fixing strip 5 and the flanges 304 of the installation groove 306 tightly together, thus realizing the double limit and fixation of the embedding plate 102. The design of this kind of fasteners and locking holes not only simplifies the installation process and improves the installation efficiency but also greatly enhances the connection strength between the fan 1 and the fixing plate 3. Even when the fan 1 generates large vibrations or is subjected to external force impacts during operation, it can ensure the stability and reliability of the vibration damping and fixing structure of the fan 1, bringing a more reassuring and stable use experience to consumers.

[0038] In some embodiments, a positioning plate 6 for positioning and cooperating with the flexible washer 2 is provided at the edge of the ventilation opening 301. The positioning plate 6 positions and limits the installation position of the fan 1 from above, preventing the fan 1 from detaching from above the fixing plate 3. The positioning plate 6 is ingeniously arranged at the edge of the ventilation opening 301, and its shape and size are carefully designed to ensure good positioning cooperation with the flexible washer 2. When the fan 1 is installed on the fixing plate 3 through the flexible washer 2, the positioning plate 6 will position the fan 1 from above and strictly limit its installation position. This design effectively prevents the fan 1 from accidentally detaching from above the fixing plate 3 during operation due to vibration or external force, ensuring the safety and stability of the equipment.

[0039] In addition, the positioning cooperation between the positioning plate 6 and the flexible washer 2 further enhances the connection strength between the fan 1 and the fixing plate 3. During the operation of the fan 1, the positioning plate 6 will continuously generate friction and extrusion with the flexible washer 2, and this physical effect helps to keep the fan 1 in a stable position on the fixing plate 3, preventing it from shaking or displacing.

[0040] In order to improve the overall stability and installation convenience of the vibration reduction fixing structure of the fan 1, the bottom of the fixing plate 3 is specially designed with an L-shaped mounting portion 303. The L-shaped mounting portion 303 not only provides a stable support for the installation of the fan 1, but also cleverly combines with the positioning plate 6 to jointly define the formation of the mounting groove 306. Specifically, the mounting portion 303 extends from the bottom of the fixing plate 3, and its shape and size are adapted to the positioning plate 6. The two are precisely matched to form a stable and easy-to-install mounting groove 306. During the installation process, the embedded plate 102 with the flexible gasket 2 can be smoothly and firmly pushed into the predetermined position along the guidance of the mounting groove 306. At this time, the positioning plate 6 positions the fan 1 from the top, and the mounting portion 303 provides support from the bottom. The two cooperate with each other to ensure the stability and accuracy of the fan 1 in the mounting groove 306. Moreover, the L-shaped mounting portion 303 also enhances the structural strength of the fixing plate 3, making the entire fan 1 vibration-damping fixing structure more stable and reliable. Even if the fan 1 generates large vibrations or is impacted by external forces during operation, the mounting portion 303 can effectively disperse and absorb these forces to prevent them from causing damage to the fixing plate 3.

[0041] Furthermore, the flexible gasket 2 is U-shaped, and the embedding groove 201 extends from the center line of the two ends of the flexible gasket 2 along the installation direction. The flexible gasket 2 is designed to be a U-shaped structure. This shape design enables it to better adapt to and wrap the embedding plate 102 at the edge of the air outlet 101 of the fan 1; at the same time, the U-shaped flexible gasket 2 includes two ends located on the same plane, and the specially opened embedding groove 201 starts from the center line of the two ends of the flexible gasket 2 and extends along the installation direction, matching the shape and size of the embedding plate 102 at the edge of the air outlet 101 of the fan 1. Such a design enables the flexible gasket 2 to fit more closely on the embedding plate 102, thereby providing better vibration reduction effect and stability, wherein the center line of the two ends is as shown in FIG. Figure 4 When the flexible gasket 2 is sleeved on the embedded plate 102 and pushed into the installation groove 306 of the fixed plate 3, the U-shaped structure can effectively disperse and absorb the vibration energy generated by the fan 1 during operation, and the close fit between the embedded groove 201 and the embedded plate 102 also prevents the fan 1 from shaking or shifting during the installation process, ensuring the accuracy and stability of the installation.

[0042] Based on the solution where the flexible washer 2 is U-shaped, the cross-section of the support member 4 is U-shaped and is embedded inside the flexible washer 2. It can also be understood that the inside of the flexible washer 2 is all embedded with the support member 4, which plays a role in strengthening the structural strength. Since the embedding groove 201 is provided at the center position of the end of the flexible washer 2, the U-shaped support member 4 can better adapt to the internal structure of the flexible washer 2 for embedding. Specifically, the support member 4 can be arranged to avoid the embedding groove 201, neither being exposed nor failing to achieve the effect of strength enhancement. As for the assembly method of the support member 4 and the flexible washer 2, the processing method of injection molding outside the support member 4 can be adopted, or the support member 4 can be assembled by being inserted from one end of the flexible washer 2 and extending to the other end.

[0043] Specifically, the support member 4 is one of a galvanized sheet, a stainless steel sheet, and an aluminum sheet. The galvanized layer can effectively prevent the support member 4 from rusting in a humid or corrosive environment, thereby extending its service life. At the same time, the galvanized sheet also has certain strength and stiffness, which can meet the basic requirements of the support member 4 for the vibration damping and fixing structure of the fan 1. The stainless steel support member 4 can maintain stable performance in various harsh environments, is not easily corroded or damaged, and also has good processing performance and aesthetics, which can meet the needs of users for high-quality products. The aluminum support member 4 can not only effectively reduce the weight of the entire vibration damping and fixing structure of the fan 1, reduce the transportation and installation costs, but also improve the heat dissipation efficiency to a certain extent, which helps to maintain the stable operation of the fan 1.

[0044] In summary, the galvanized sheet, the stainless steel sheet, and the aluminum sheet are all high-quality materials for manufacturing the support member 4 of the vibration damping and fixing structure of the fan 1. Which material to specifically select needs to be comprehensively considered according to the actual use environment and user requirements. No matter which material is selected, we will ensure that the support member 4 has sufficient strength and stiffness to provide a stable and reliable supporting effect and meet the performance requirements of the user for the vibration damping and fixing structure of the fan 1.

[0045] In addition, the flexible gasket 2 is one of a rubber gasket, a silicone gasket, a polytetrafluoroethylene gasket and a fiber gasket. The rubber gasket is popular for its good elasticity and wear resistance. It can effectively absorb and disperse the vibration energy generated when the fan 1 is running, and reduce the impact of vibration on the equipment. At the same time, the rubber gasket also has certain oil resistance, water resistance, acid and alkali resistance and other properties, and is suitable for a variety of working environments. The silicone gasket is famous for its excellent high temperature resistance, low temperature resistance, aging resistance and other properties. The silicone gasket can maintain stable performance under extreme temperature conditions, is not easy to deform or age, thereby ensuring the long-term effectiveness of the vibration reduction fixing structure of the fan 1. In addition, the silicone gasket also has good sealing and insulation properties, which can meet the needs of specific applications. The polytetrafluoroethylene gasket is favored for its extremely low friction coefficient and excellent corrosion resistance. It can effectively reduce the friction and wear between the fan 1 and the fixing plate 3, and reduce noise and vibration. At the same time, the polytetrafluoroethylene gasket also has good chemical corrosion resistance and can resist the erosion of various acids, alkalis, salts and other chemical substances. Fiber washers are known for their high strength, high modulus and good fatigue resistance. They can maintain stable performance when subjected to large loads and vibrations, and are not easily damaged or failed. Fiber washers also have good heat resistance and aging resistance, and can maintain their stable performance under high temperature or long-term use conditions.

[0046] In summary, the rubber gasket, silicone gasket, polytetrafluoroethylene gasket and fiber gasket provided each have their own unique advantages and applicable scope. When selecting the flexible gasket 2, it is necessary to comprehensively consider the specific application scenario, working environment and performance requirements to ensure that the vibration reduction fixing structure of the fan 1 can achieve the best vibration reduction effect and stability.
