Abstract
Description
Technical Field
[0001] This utility model relates to the field of shock absorption technology, and in particular to a server shock absorption structure. Background Technology
[0002] In the context of the rapid development of modern information technology, servers, as core devices for data storage, processing, and transmission, are of paramount importance in terms of stability and reliability. However, servers are often affected by external vibrations during operation. For example, in data center environments, there may be vibrations generated by the operation of large cooling equipment and generators; servers deployed in industrial sites may be subject to vibrations caused by the operation of production equipment and vehicle movement. The impact of external vibrations on servers is multifaceted. Vibration may cause the read / write heads of storage devices such as hard drives to collide with the platters, resulting in data corruption or loss; it may also loosen internal components such as circuit boards and connectors, causing poor contact and affecting the normal communication and operation of the server; long-term vibration can even accelerate the aging of internal server components, shorten the server's lifespan, and increase the operating costs of enterprises. Utility Model Content
[0003] The purpose of this invention is to provide a server vibration damping structure, which is installed at the bottom of the server to effectively absorb and buffer external vibrations, reduce the impact of vibrations on the server, and ensure that the server can operate stably in various environments.
[0004] To achieve the above objectives, this utility model provides a server vibration damping structure, including a vertically arranged central shaft, a tube sleeved outside the central shaft, and an elastic body; a lower mounting plate is fixed to the bottom of the central shaft extending from the tube, and a pressure plate is installed at the top; an upper mounting plate is fixed to the top of the tube; a filling area is formed between the central shaft, the tube, the pressure plate, and the lower mounting plate, and the elastic body fills this area, with its surrounding components in contact with it forming compression friction; the lower mounting plate is a fixed end, fixed to the ground or a fixed base; the upper mounting plate is a floating end, fixed to the bottom of the server rack or chassis.
[0005] With the above structure, by installing this device at the bottom of the server, the device, through the combination design of the central shaft, tube and elastomer, can absorb multi-directional vibrations through the squeezing friction between the elastomer and the surrounding components, reducing the impact of vibration on the server and ensuring the stable operation of the server.
[0006] Preferably, the bottom of the elastomer has a raised flange at one end of the lower mounting plate, and the bottom of the tube is engaged with the raised flange, without contacting the lower mounting plate. This design avoids direct contact between the tube and the lower mounting plate, reduces the longitudinal transmission of vibration between the tube and the lower mounting plate, and further improves the shock absorption effect.
[0007] Preferably, the top of the central shaft is provided with an upwardly extending threaded rod, and a fixing nut is screwed onto the threaded rod. The fixing nut presses the pressure plate tightly against the elastic body. By rotating the fixing nut, the degree of pressure of the pressure plate on the elastic body can be adjusted, thereby changing the preload of the elastic body to adapt to different vibration damping requirements.
[0008] Preferably, a cap is provided at the top of the tube, which closes the top of the tube. A compression spring is clamped between the cap and the pressure plate. The compression spring can assist the elastomer in shock absorption to a certain extent. When the external vibration is large, the compression spring can provide additional cushioning and further reduce the impact of vibration on the server. At the same time, when compressed, the compression spring can provide a certain compressive force to the pressure plate 12, causing it to press against the elastomer, causing the elastomer to deform and expand, increasing the compression friction of the parts in contact with it, thereby improving the shock absorption effect.
[0009] Preferably, both the tube and the central shaft have square cross-sections, and they rotate at a 45° angle in the direction of their cross-sections, forming four right-angled triangular spaces. Each space is filled with an elastomer. When the pressure plate presses the elastomer from the top, the elastomer expands, and its surrounding walls exert pressure and friction against the tube and the central shaft. This special shape design and the way the elastomer is filled allow the elastomer to better generate friction with the tube and the central shaft when subjected to vibration, thereby improving multi-directional damping capability and achieving a better damping effect.
[0010] Preferably, the elastomer is a right-angled triangular structure that mimics the spatial shape of a right-angled triangle. This mimicry design allows the elastomer to better fill the space enclosed by the tube and the central axis, ensuring a tight fit and improving the stability and shock absorption performance of the elastomer.
[0011] Preferably, the elastomer is made of rubber. Rubber has good elasticity and damping properties, which can effectively absorb and buffer vibration energy, making it an ideal material for making shock-absorbing elastomers.
[0012] Preferably, the pressure plate has a structure that is thicker in the middle and thinner at the periphery. This structure can increase the strength of the pressure plate and prevent the fixing nut from deforming when it interacts with the pressure plate.
[0013] After adopting the above technical solution, the beneficial effects of this utility model are:
[0014] This utility model provides a server vibration damping structure that solves the technical problem that servers are easily affected by external vibrations in the prior art. By installing this device at the bottom of the server, it achieves a vibration damping and isolation effect, ensuring that the server can operate stably in various environments.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] The orientations mentioned in this specification are based on the orientation of the server shock absorption structure of this utility model when it is working normally, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.
[0023] like Figure 1 and Figure 2 As shown in the figure, a server vibration damping structure includes a vertically arranged central shaft 1, a tube 2 sleeved on the outside of the central shaft 1, and an elastic body 3.
[0024] A lower mounting plate 11 is fixed to the bottom of the central shaft 1 extending from the tube 2, forming an inverted "T" shape with the central shaft 1. In this embodiment, the central shaft 1 and the lower mounting plate 11 are integrally formed; however, in practical applications, a detachable structure can also be used, such as connecting them together via a threaded connection. A pressure plate 12 is mounted on the top of the central shaft 1; an upper mounting plate 21 is fixed to the top of the tube 2. The central shaft 1, tube 2, pressure plate 12, and lower mounting plate 11 form a filling area, in which the elastic body 3 is filled, and its surrounding components in contact with it experience compression friction.
[0025] Elastomer 3 is made of rubber. Rubber has good elasticity and damping properties, which can effectively absorb and buffer vibration energy, making it an ideal material for making shock-absorbing elastomer 3.
[0026] The lower mounting plate 11 is the fixed end, which is fixed to the ground or a fixed base; the upper mounting plate 21 is the floating end, which is fixed to the bottom of the server rack or chassis; multiple of these devices are evenly fixed to the bottom of each server rack or chassis to ensure support stability.
[0027] The server vibration damping structure of this utility model adopts a combination design of central shaft 1, tube 2 and elastic body 3. The compression friction between the elastic body 3 and the surrounding components can absorb multi-directional vibration, reduce the impact of vibration on the server, and ensure the stable operation of the server.
[0028] In another embodiment, the bottom of the elastomer 3 is provided with a flange 31 at one end of the lower mounting plate 11, and the bottom of the tube 2 is engaged with the flange 31, so that the bottom of the tube 2 does not contact the lower mounting plate 11. This design can avoid direct contact between the tube 2 and the lower mounting plate 11, reduce the longitudinal transmission of vibration between the tube 2 and the lower mounting plate 11, and further improve the shock absorption effect.
[0029] In another embodiment, the pressure plate 12 is installed in an adjustable manner: a threaded rod 10 extending upwards is provided at the top of the central shaft 1, and a fixing nut 101 is screwed onto the threaded rod 10. The fixing nut 101 presses the pressure plate 12 tightly above the elastic body 3. In the uncompressed state, the height of the elastic body 3 is higher than the height of the central shaft 1, thereby facilitating the compression of the elastic body 3 by the pressure plate 12. By rotating the fixing nut 101, the degree of compression of the elastic body 3 by the pressure plate 12 can be adjusted, thereby changing the preload of the elastic body 3 to adapt to different vibration damping requirements.
[0030] The pressure plate 12 is further optimized by having a structure that is thicker in the middle and thinner at the periphery. This structure can increase the strength of the pressure plate 12 and prevent the pressure plate 12 from deforming when the fixing nut 101 exerts force on it.
[0031] In another embodiment, a cap 22 is provided on the top of the tube 2. The cap 22 is detachably mounted on the upper mounting plate 21 and closes the top of the tube 2. A compression spring 23 is held between the cap 22 and the pressure plate 12. The compression spring 23 can assist the elastomer 3 in shock absorption to a certain extent. When the external vibration is large, the compression spring 23 can provide additional buffering effect, further reducing the impact of vibration on the server. At the same time, when compressed, the compression spring 23 can provide a certain compressive force to the pressure plate 12, causing it to press the elastomer 3 tightly, causing the elastomer 3 to deform and expand, increasing the compression friction of the parts in contact with it, thereby improving the shock absorption effect.
[0032] In another embodiment, the special shape of the tube 2 and the central shaft 1, and the filling method of the elastomer 3.
[0033] like Figure 3 , Figure 4 and Figure 5 As shown, both the tube 2 and the central shaft 1 have square cross-sections. The tube 2 and the central shaft 1 rotate at a 45° angle in the direction of their cross-sections, forming four right-angled triangular spaces, each filled with an elastomer 3. When the pressure plate 12 presses the elastomer 3 from the top, the elastomer 3 expands, and its surrounding walls exert pressure and friction against the tube 2 and the central shaft 1. This special shape design and the filling method of the elastomer 3 allow it to better generate friction with the tube 2 and the central shaft 1 when subjected to vibration, thereby improving multi-directional damping capability and achieving a better damping effect.
[0034] Further optimization resulted in the elastomer 3 being a right-angled triangle structure that mimics the spatial shape of a right-angled triangle. This mimicry design allows the elastomer 3 to better fill the space enclosed by the tube 2 and the central axis 1, ensuring a tight fit and improving the stability and shock absorption performance of the elastomer 3.
[0035] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
