Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and in particular to a chassis shock absorber. Background Technology

[0002] In the field of electronic equipment, various precision electronic components are usually installed inside the chassis, such as hard drives and motherboards in server chassis.

[0003] When existing computer cases are used in special environments, such as industrial production workshops and mobile vehicle-mounted equipment, they are subjected to external forces such as vibration and impact. If these vibrations are directly transmitted to the electronic components inside the case, they may cause problems such as component damage, loose connections, and data read / write errors, which seriously affect the normal operation and service life of the equipment. Therefore, there is a need to provide a computer case shock absorber to effectively reduce the impact of external vibrations on the inside of the case. Utility Model Content

[0004] The purpose of this utility model is to provide a chassis vibration damper to solve the problem mentioned in the background art, where existing chassis, when used in some special environments, may cause damage to components, loose connections, and data read / write errors if these vibrations are directly transmitted to the electronic components inside the chassis, seriously affecting the normal operation and service life of the equipment.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A chassis vibration damper includes: a chassis frame and vibration damping components;

[0007] The shock-absorbing component includes a support base frame, a support base plate, a support top plate, and shock-absorbing springs. The lower surface of the chassis frame is connected to the support base frame. The support base plate is symmetrically connected to the top of the inner surface of the support base frame. The lower surface of the support top plate is connected to the upper surface of the support base plate through the shock-absorbing springs. The chassis frame is connected to the top of the support top plate. Extension blocks are connected to the upper parts of both sides of the outer surface of the support base frame. Limiting rods are connected to the top of the extension blocks. Limiting rings are slidably sleeved on the outer surface of the limiting rods, and one side of the limiting rings is connected to one side of the outer surface of the chassis frame.

[0008] The system also includes fixing components, which include rubber pillars, sliding sleeves, telescopic plates, docking holes, and docking rods. Sliding sleeves are connected to both sides of the outer surface of each supporting base plate, and telescopic plates are connected to both sides of the outer surface of each supporting top plate. The telescopic plates at corresponding positions are inserted into the sliding sleeves and slidably connected. Multiple rubber pillars are equidistantly bonded to the inner surface of the limiting ring. A side plate is connected to one side of the outer surface of the supporting top plate, and a docking hole is opened in the middle of the side plate. Docking rods are symmetrically connected to the bottom of the chassis frame, and the docking rods at corresponding positions are inserted into the docking holes and slidably connected.

[0009] The support base has external through holes on the front and rear corresponding sides of its outer surface. Each external through hole has a support strip slidably connected inside. The support base plate has U-shaped docking grooves at both the front and rear ends. Each support strip has a docking strip at one end of its inner side that mates with the docking groove at the corresponding position. The docking strip is inserted into the docking groove to fix the support base plate.

[0010] Each of the supporting base plates has supporting blocks connected to its front and rear sides, and a hole is opened in the middle of the supporting block. Each of the supporting bars has a plug connected to one side of its outer surface, and the plug is inserted into the hole.

[0011] A limit block is fixedly connected to the other side of the outer surface of the support bar.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a support base, a support base plate, a support top plate, and a shock-absorbing spring at the bottom of the chassis frame. A connecting rod is inserted into the connecting hole, fixing the chassis frame to the top of the support top plate. When the support base is subjected to vibration, the vibration is first transmitted to the support base plate, which then transmits the vibration to the shock-absorbing spring. The shock-absorbing spring is compressed, absorbing some of the vibration energy and undergoing elastic deformation, converting the vibration into the spring's elastic potential energy. This effectively reduces the vibration transmitted to the inside of the chassis, protecting the electronic components inside the chassis frame.

[0014] In addition, based on the above-mentioned beneficial effects, by providing a connecting strip, a support strip, a hole, and a plug, after the shock-absorbing spring has been used for a long time, the support strip can be moved inside the outer through hole, allowing the staff to pull the support strip outward, so that the connecting strip separates from the connecting groove, and the plug separates from the hole at the same time. The support base plate can then be pulled out, making it easy to disassemble and facilitate the maintenance or replacement of the internal shock-absorbing spring, reducing the difficulty of disassembly.

[0026] The shock-absorbing components include a support base frame 21, a support base plate 22, a support top plate 23, and a shock-absorbing spring 24. The lower surface of the chassis frame 11 is connected to the support base frame 21. The support base plate 22 is symmetrically connected to the top of the inner surface of the support base frame 21. The lower surface of the support top plate 23 is connected to the upper surface of the support base plate 22 through the shock-absorbing spring 24. The chassis frame 11 is connected to the top of the support top plate 23. Extension blocks 27 are connected to the upper part of both sides of the outer surface of the support base frame 21. A limiting rod 28 is connected to the top of the extension block 27. A limiting ring 26 is slidably sleeved on the outer surface of the limiting rod 28, and one side of the limiting ring 26 is connected to one side of the outer surface of the chassis frame 11.

[0027] This invention features a support base, a support base plate, a support top plate, and a shock-absorbing spring at the bottom of the chassis frame. A connecting rod is inserted into the connecting hole, fixing the chassis frame to the top of the support top plate. When the support base is subjected to vibration, the vibration is first transmitted to the support base plate, which then transmits the vibration to the shock-absorbing spring. The shock-absorbing spring is compressed, absorbing some of the vibration energy and undergoing elastic deformation, converting the vibration into the spring's elastic potential energy. This effectively reduces the vibration transmitted to the inside of the chassis, protecting the electronic components inside the chassis frame.

[0028] The system also includes fixing components, which include rubber pillars 31, sliding sleeves 32, telescopic plates 33, docking holes 34, and docking rods 35. Each of the supporting base plates 22 has sliding sleeves 32 connected to both sides of its outer surface, and each of the supporting top plates 23 has telescopic plates 33 connected to both sides of its outer surface.

The docking rods 35 at corresponding positions are inserted into the docking holes 34 and slidably connected.

[0029] It should be noted that the docking holes, docking rods, sliding sleeves, and telescopic plates can serve as guides. In addition, the structure of the rubber columns can achieve a shock absorption effect in the radial direction.

A plug 45 is connected to one side of the outer surface of each supporting bar 47. The plug 45 is inserted into the hole 42.

[0032] A limiting block 48 is fixedly connected to the other side of the outer surface of the support bar 47.

[0033] In use, the support base plate 22 is first installed inside the support base frame 21. Then, the support bar 47 is pushed, and the support bar 47 moves inside the outer through hole 41, so that the mating bar 44 is embedded inside the mating groove 43. At the same time, the insertion rod 45 is inserted into the hole 42 to install and fix the support base plate 22. After long-term use, by moving the support bar 47 inside the outer through hole 41, the operator can pull the support bar 47 outward, so that the mating bar 44 is separated from the mating groove 43, and the insertion rod 45 is separated from the hole 42. The support base plate 22 can be pulled out and disassembled, which facilitates the maintenance or replacement of the internal shock-absorbing spring 24 and reduces the difficulty of disassembly.
