[0002] A computer, commonly known as a PC, is an electronic computing device used for high-speed computing. It can perform numerical calculations, logical calculations, and also has a storage and memory function. The mainframe box is an important part of a computer, usually a metal or plastic casing for housing the main hardware devices of the computer.

[0003] In industrial production, some equipment is equipped with sensors to transmit the operating parameters of the equipment to the computer in real time. Through specialized monitoring software, staff can remotely monitor the equipment status, timely detect abnormal situations, and perform maintenance in advance to prevent production interruption caused by equipment failures.

[0004] In some production workshops, huge impact forces will be generated. The impact forces will cause strong vibrations on the ground and equipment. For example, during the forging process, when a large air hammer is working, each hammer blow will generate an impact force of thousands of Newtons or even tens of thousands of Newtons. These impact forces will be transmitted to the surrounding equipment and the ground through the foundation, which may cause the mainframe box and its internal components to loosen, affecting its normal operation and service life. Content of the Utility Model

[0005] In view of the above deficiencies, the utility model provides a shock absorption device for a mainframe box, which can reduce vibrations and prevent damage to the mainframe box and its internal components.

[0013] Further, the pressing member includes a first plate body; the energy-consuming member includes a damper; and the bearing member includes a bearing plate.

[0014] Further, a plurality of strip-shaped second through holes are provided on the bearing plate, enabling gas to pass through the bearing plate in the vertical direction.

[0015] Further, a fan is provided on the lower surface of the bearing plate. The fan can cause the gas below to flow upward through the bearing plate, and the fan can provide a downward pulling force to the bearing plate.

[0016] Further, the top surface of the first plate body is connected to a second plate body through a first spring.

[0017] Further, the supporting member includes a vertical pipe. A first through hole is provided on the side wall of the vertical pipe.

[0032] 2. Main chassis. Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] Referring to Figures 1 - 8 , the present utility model protects a shock absorption device for a main chassis. For the convenience of understanding, Figure 1The main chassis 2 is placed on the shock absorption device 1, and the main chassis 2 is not within the scope of protection of this application. In addition, the main chassis 2 refers to the main chassis and its internal components, which is simply referred to as the main chassis 2 for convenience of description hereinafter. The shock absorption device 1 includes:

[0035] A bottom component, which is used for bearing weight and can be stably set on the ground. The bottom component has a relatively large self-weight, which is convenient for bearing weight and can also increase the stability of the entire device.

[0036] A pressing component is provided above the bottom component, and the bottom component and the pressing component are connected by an energy-consuming component, which can consume the energy of vertical vibration. The pressing component presses on the energy-consuming component under the action of gravity, and the weight of the pressing component is also relatively large, which is convenient for pulling the bearing component to be suspended.

[0037] A bearing component is provided above the pressing component, and the main chassis 2 can be placed on the bearing component.

[0038] The bearing component is connected to the pressing component through a connecting component, and the connecting component is a flexible elastic connecting component.

[0039] A plurality of supporting components are provided on the bottom component, and the supporting components can support the connecting component to make the bearing component suspended.

[0040] In this utility model, by setting the supporting component, the supporting component can be used as the fulcrum of the connecting component, so that the pressing component can pull the bearing component through the connecting component under its own gravity, making the bearing component suspended. In the actual working scenario, the main vibration caused by equipment similar to a large air hammer to the main chassis 2 and the force that causes the internal components of the main chassis to loosen is the vertical vibration. Suspending the bearing component aims to prevent the vertical vibration on the ground from being directly transmitted to the main chassis 2, and to prevent the internal components of the main chassis 2 from loosening to the greatest extent. By setting the bottom component, it can be stably set on the ground, ensuring the stability of the entire device. By setting the energy-consuming component, the vibration energy of the ground is consumed when passing through the energy-consuming component, preventing a large amount of vibration energy from affecting the pressing component. By setting the flexible elastic connecting component, the vibration energy causes the connecting component to deform when passing through the connecting component, further consuming the vibration energy and preventing damage to the main chassis 2.

[0041] Reference Figure 1 or Figure 2 , in a specific embodiment, the bottom component includes a base 11, and the base 11 is a metal base or a concrete base. Among them, the base 11 can be placed on the ground or fixed to the ground by screws or welding, aiming to make the base 11 more firm.

[0042] In this embodiment, by setting a metal base or a concrete base, the weight of the base 11 is increased, so that when the base 11 faces relatively large vibrations, it can maintain its own stability, avoid large-scale shaking, and thus avoid large-scale shaking of the main chassis 2.

[0043] Reference Figure 2 In a specific embodiment, the pressing member includes a first plate body 17, which can be a metal plate or a cement plate. The first plate body 17 itself also needs to have a relatively large weight to facilitate pulling the bearing plate 15 by its own weight.

[0044] The energy-consuming member can be a spring, a rubber column, and a damper 12. Preferably, it is the damper 12. A plurality of dampers 12 are provided, and the dampers 12 are commercially available conventional viscous dampers, which can consume the energy of vibration.

[0045] The bearing member includes a bearing plate 15. The bearing plate 15 is a rigid plate, and the weight of the bearing plate 15 is lighter than that of the first plate body 17. The bottom end of each damper 12 is fixed on the upper surface of the base 11, and the top end of the damper 12 is fixed on the lower surface of the first plate body 17.

[0046] In this embodiment, by providing the damper 12 between the first plate body 17 and the base 11, the huge impact force or vibration transmitted from the ground can be consumed, especially the vibration in the vertical direction. Of course, the damper 12 can only consume the impact force or vibration, and within a certain range of impact force, the impact force or vibration can be exhausted, rather than exhausting all the impact force and vibration. In this way, no vibration is transmitted to the first plate body 17, or the vibration transmitted to the first plate body 17 is less than the vibration transmitted from the ground to the base 11.

[0047] Reference Figure 7 and Figure 8 In a specific embodiment, a plurality of strip-shaped second through holes 151 are provided on the bearing plate 15, so that gas can pass through the bearing plate 15 in the vertical direction. The provision of the second through holes 151 in this embodiment can increase air circulation and is beneficial to the heat dissipation of the main chassis 2.

[0048] Reference Figure 7 and Figure 8 In a specific embodiment, a fan 19 is fixedly provided on the lower surface of the bearing plate 15. The fan 19 can make the gas below pass through the bearing plate 15 and flow upward, and the fan 19 can provide a downward pulling force to the bearing plate 15.

[0049] In this embodiment, the fan 19 has two functions. Among them, the first function is heat dissipation. Since in the natural environment, hot air will automatically rise compared with cold air, setting the fan 19 can accelerate the air flow in the vertical direction and enable the cold air below to dissipate heat from the main chassis 2 as much as possible. The second function is to provide a downward pressure, which is also the main function. The wind force of the fan 19 is upward, and the wind force will give the fan 19 itself a downward reaction force, so that the fan 19 can pull the bearing plate 15 downward and increase the stability of the bearing plate 15. In addition, the fan 19 is provided below the bearing plate 15, and the center of gravity is lower, so the stability is better.

[0050] Reference Figure 2 、 Figure 6 and Figure 7 In a specific embodiment, the top surface of the first plate body 17 is fixedly connected to the bottom end of the first spring 18, and the top end of the first spring 18 is fixedly connected to the bottom surface of the second plate body 16. Among them, the number of the first springs 18 is multiple, the spring constant of the first springs 18 is large, the material can be selected as 65Mn steel, or the wire diameter of the first springs 18 can be increased. In short, the first springs 18 should meet the characteristic of small deformation, so that the first springs 18 can consume vibration energy and basically do not deform during conventional factory operations. The second plate body 16 can be a rigid plate or a flexible plate, preferably a flexible plate. The material of the flexible plate is rubber or silica gel.

[0051] In this embodiment, the second plate body 16 is provided to play a buffering role. When the connecting member is selected as a rope with a large elasticity, the main chassis 2 may have a large swing in the vertical direction. The second plate body 16 is provided to prevent the main chassis 2 from directly hitting the first plate body 17. Of course, in other embodiments, the fan 19 may not be provided, and the length of the connecting member may be set longer, so that a small part of the weight of the main chassis 2 falls on the second plate body 16. Since the spring constant of the first springs 18 is large and there is basically no deformation, the second plate body 16 can increase the friction force of the main chassis 2 in the horizontal direction and can reduce the horizontal sway to a certain extent; of course, the second plate body 16 also basically does not sway in the vertical direction. Therefore, the second plate body 16 and the first springs 18 can assist in increasing the stability of the bearing plate 15.

[0052] Reference Figure 2 and Figure 3 In a specific embodiment, the support member can be a hollow plate, a hollow block or a vertical pipe 13, preferably a vertical pipe 13.

[0053] The number of the vertical pipes 13 is multiple. The bottom ends of the vertical pipes 13 are fixed on the base 11. The vertical pipes 13 are arranged around the first plate body 17 and do not contact the first plate body 17. A first through hole 131 is provided on the side wall of the vertical pipe 13. One end of the connecting member is fixed on the first plate body 17, and the other end of the connecting member passes through the first through hole 131 and extends out from the top end of the vertical pipe 13 to be connected to the bearing plate 15.

[0054] In this embodiment, the vertical pipes 13 are provided, which can limit the posture of the connecting member in the vertical direction, facilitate adjusting the extending length of the connecting member from the vertical pipes 13, and enable the bearing plate 15 to remain horizontal after the connecting member is connected to the bearing plate 15. The top ends of the vertical pipes 13 serve as fulcrums to support the connecting member.

[0055] Reference Figure 2 and Figure 6, in a specific embodiment, the connecting member includes a shock-proof connecting member 14, and the shock-proof connecting member 14 can consume the energy of vibrations in the horizontal direction. It should be specifically noted that: the vibrations in the horizontal direction refer to the vibrations that the vertical pipe 13 may have in the horizontal direction that are invisible to the naked eye under natural conditions. To avoid the influence of such vibrations on the main chassis 2, the shock-proof connecting member 14 is provided. The shock-proof connecting member 14 consumes the energy of vibrations in the horizontal direction through springs or flexible members. In this embodiment, the shock-proof connecting member 14 is provided, which can consume the vibrations in the horizontal direction to a certain extent and ensure the stability of the main chassis 2.

[0056] Reference Figure 5 and Figure 6 , in a specific embodiment, the shock-proof connecting member 14 includes a rope 141. One end of the rope 141 is fixedly connected to the first plate body 17, and the other end of the rope is fixedly connected to the bearing plate 15. According to actual needs, the rope 141 can be selected as a nylon rope, a polyamide rope, a steel wire rope, a cable rope, etc.

[0057] A counterweight 144 is sleeved on the rope 141. The counterweight 144 is fixed on the rope 141, and there is a gap between the counterweight 144 and the inner wall of the vertical pipe 13. A flexible block 143 is movably sleeved on the outer side of the rope 141. The flexible block 143 has a through hole in the center, and the rope 141 can pass through. The outer wall of the flexible block 143 is fixedly connected to one end of the second spring 142, and the other end of the second spring 142 is fixedly connected to the inner wall of the vertical pipe 13. The flexible block 143 is arranged at the inner top end of the vertical pipe 13.

[0058] In this embodiment, the counterweight 144 is provided. When the vertical pipe 13 or the base 11 is subjected to lateral vibrations or impact forces, the counterweight 144 shakes. The counterweight 144 is equivalent to a damper and can consume part of the lateral vibration energy, so that the rope 141 is minimized in the horizontal direction and the stability of the main chassis 2 is ensured. The flexible block 143 has two functions. The first function is to consume the vibrations in the horizontal direction; the second function is to make the rope 141 as close as possible to the axis of the vertical pipe 13. Compared with the rope 141 being close to the inner wall of the vertical pipe 13, the rope 141 is easier to move. In this embodiment, the sum of the weights of the first plate body 17 and the counterweight 144 is the first weight, and the sum of the weights of the bearing plate 15, the main chassis 2 and the fan 19 is the second weight, and the first weight is greater than or equal to the second weight.

[0059] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited by this. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
