Data centers are often provided with a large number of servers that are often placed in racks with shelves. The server device can generate vibration or jitter during operation, which not only causes great noise, but also affects the service life and efficiency of the server.
Aiming at the problem of vibration reduction and vibration prevention of a server cabinet, the prior art mainly uses a spring arranged at the bottom of the cabinet to buffer vibration of the whole cabinet, the integral vibration reduction has the defect that only force generated when the cabinet vibrates downwards can be buffered, vibration or vibration generally moves up and down, when the cabinet moves upwards due to inertia or mechanical vibration after moving downwards, the spring firstly changes into a free state from a compression state and then changes into a tensile state according to the buffering principle of the spring, in the process, the upward thrust generated by the spring against the compression force is firstly received in the upward movement process of the server, the upward movement trend of the server is further aggravated, the vibration reduction effect is not soft enough, and the stability of the server is not facilitated. In addition, the spring is easy to cause the conditions of blockage, fracture, fault and the like due to the mechanical structure, so that the maintenance is frequent, and the maintenance cost is too high for a large number of data server supports in the Internet center. In addition, most of the existing server cabinet damping structures are provided with supports at four corners below the cabinet body, and the defects of the design are that the cabinet body cannot play a good role in damping or stabilizing when the cabinet body is tilted or vibrated in directions other than the four corners (such as directions between two adjacent corners).

When the second moving plate 802 moves upward, the buffer medium above the second moving plate is extruded to re-enter the fourth chamber 804, the fourth chamber 804 has limited capacity, and is extruded into the third chamber 803 again, so that the state before the first vibration is restored, and the state is ready for the next vibration.
The bottom surface is the circumscribed circle of the bottom surface of cabinet body 1 on the base 5, in order to take place when the vibrations or the slope of becoming the direction at cabinet body 1, promptly when the atress point is on one side of cabinet body 1, in order to evenly transmit the pressure to base 5, increase the area of atress, also strengthened solid stability simultaneously, the region of the bottom surface on the base 5 except cabinet body 1 bottom surface is equipped with pressure transmission spare 12, as shown in fig. 6, the length direction of pressure transmission spare 12 is followed the radial direction of the bottom surface on the base 5 sets up. The pressure transmission device can also be arranged along the side length perpendicular to the square bottom surface, or in any arrangement direction which is beneficial to pressure transmission.
Example 5
Embodiment 5 provides an optimized solution on the basis of embodiment 4, as shown in fig. 7 and 8, the base 5 is in a shape of a circular table, the third chamber 803 is a space where a cylinder formed by penetrating the bottom surface downwards with a concentric circle of the top surface of the base 5 as the bottom surface, the radius of the concentric circle is smaller than the radius of the top surface of the base 5, the rest space inside the base 5 is the fourth chamber 804, and the second partition 805 is disposed along the side surface of the cylinder. The third connecting rod 10 and the third moving plate 9 are arranged in the fourth chamber 804, a plurality of through holes are arrayed in the annular area outside the concentric circles on the second pressure portion 7, the third connecting rod 10 penetrates through the through holes in the annular area on the second pressure portion 7, the third moving plate 9 is connected with the cabinet body 1, the third moving plate 9 is sleeved in the fourth chamber 804, and moves in the fourth chamber 804 along with the vibration of the cabinet body 1.
The base 5 is designed into a round table shape, mainly aims to overcome the technical defect that four supports are designed at four corners of the existing cabinet body 1, and has better ground grabbing capability and more stability by adopting a round table structure with a small upper part and a large lower part, so that the balance of the cabinet body 1 in all directions can be kept more stably. To further enhance the grip of the base, anti-slip means, such as rubber pads, anti-slip rings, etc., may be provided at the contact surface of the base with the ground. The space of the third chamber 803 is a middle part of the circular truncated cone-shaped cylinder, because considering that the cabinet body 1 is a square bottom surface and does not occupy the upper bottom surface of the whole circular truncated cone, the cabinet boundary between two adjacent cabinet legs is inside the upper bottom surface, when the direction of the inclination or vibration of the cabinet body 1 is the side length direction of the cabinet body 1, that is, the stress point is on one side of the cabinet body 1, the damping method can be used for buffering, but if the direction of the inclination or vibration of the cabinet body 1 is the diagonal direction of the cabinet body 1, that is, the stress point is at the corner of the cabinet body 1, at the moment, if the third chamber 803 is a space of a cylinder taking the upper bottom surface of the circular truncated cone as the bottom surface, then the stress point is just located at the junction of the third chamber 803 and the fourth chamber 804, the damping effect cannot be well achieved, and the design of the scheme is needed at the moment, the third chamber 803 is the space where the cylinder formed by taking the concentric circle of the upper bottom surface of the base 5 as the bottom surface downwards runs through, the bottom surface, that is smaller than the radius of the cylinder on the base 5, that is the upper bottom surface of the third chamber, that is the corner of the circular truncated cone, at the corner, the space of the third chamber is the middle part of the cabinet body 1, the circular truncated cone, the stress point is the corner, the space of the cabinet body 1 can be used for damping the third chamber 3, the vibration plate and the damping medium can be damped by the third chamber 3 and the damping medium to the third chamber 1 and the damping medium 1.
The design can soft shock absorption when the server cabinet body 1 shakes or topples over in any direction, and if the stress point of the cabinet body 1 is in the period of the third chamber and the fourth chamber or spans the third chamber and the fourth chamber, the good shock absorption effect can be achieved through the double buffering effect of the third chamber and the fourth chamber.
There are, of course, many other embodiments of the invention that can be made by those skilled in the art in light of the above teachings without departing from the spirit or essential scope thereof, but that such modifications and variations are to be considered within the scope of the appended claims.
