Description

Technical Field

[0001] The utility model belongs to the technical field of network information servers, in particular to an earthquake-resistant mainboard structure of a server. Background Art

[0002] Since a server is a high-performance computer, its structure must have many similarities with ordinary computers, such as CPU, memory, hard disk, various buses, etc. Its high performance is mainly reflected in high-speed computing power, long-term reliable operation, and strong external data throughput capabilities.

[0003] The motherboard, also known as the mainboard, is one of the most basic and important components of a server. The motherboard is generally a rectangular circuit board on which the main circuit systems that make up the server are installed, generally including BIOS chip, I / O control chip, keyboard and panel control switch interface, indicator light connector, expansion slot, DC power supply connector for the motherboard and plug-in card, and other components.

[0004] The motherboard is connected to the screw columns inside the chassis through bolts. The screw columns can raise the motherboard so that there is a certain gap between the bottom of the motherboard and the chassis. Since the two are rigidly connected, the connection part is prone to breakage when subjected to external impact. In severe cases, the entire computer motherboard will crack and damage the internal circuit of the motherboard.

[0005] In view of the above-mentioned drawbacks, some existing motherboards have begun to make changes to the screw columns and added spring structures. However, the spring structure will have a secondary bounce when receiving force feedback, causing the motherboard to shake. Therefore, it is necessary to set up a new structure on the existing basis to enable it to resist longitudinal and lateral impact forces and improve the seismic performance of the motherboard. Utility Model Content

[0006] The purpose of the utility model is to provide a server anti-vibration mainboard structure in order to solve the above-mentioned problem.

[0007] The technical solution adopted by the utility model is as follows: a server anti-seismic mainboard structure, including a server chassis and a mainboard, the mainboard is installed inside the server chassis, heat dissipation ports are arranged on both sides of the server chassis, and installation slots are integrated at the four corners of the mainboard;

[0008] The bottom of the server chassis is provided with a buffer structure capable of longitudinally absorbing shocks of the mainboard;

[0009] A support mechanism capable of reducing the impact force on the mainboard is arranged inside the installation groove;

[0010] The buffer structure includes: a support seat, a connecting groove, a buffer head, a telescopic support rod, a piston rod, and a spring. A support seat is provided at a position corresponding to the installation groove at the bottom of the server chassis, a buffer head is slidably arranged inside the support seat, and a connecting groove is connected to the upper end of the buffer head;

[0011] The bottom of the server chassis is rotatably connected to a telescopic support rod near both sides of the support seat, the interior of the telescopic support rod is slidably connected to a piston rod, and the exterior of the piston rod is nested with a spring;

[0012] The supporting mechanism includes: a hydraulic buffer cavity, a connector, a shock-absorbing rubber seat, and a mounting hole. The shock-absorbing rubber seat is threadedly connected inside the mounting groove, the mounting hole is installed inside the shock-absorbing rubber seat through the hydraulic buffer cavity, and the connector is installed inside the hydraulic buffer cavity.

[0013] Among them, the other end of the piston rod is rotationally connected to the connecting groove, the hydraulic buffer chamber is made of rubber elastic material, and hydraulic oil is arranged inside. The connecting body is an elastomeric structure arranged back to back, and the material is PP plastic, and its end is connected to the hydraulic buffer chamber. The number of hydraulic buffer chambers is 4, which are evenly distributed around the mounting hole.

[0014] Wherein, a stud is threadedly connected inside the connection groove, and the stud passes through the mounting hole.

[0015] Among them, in each group of the buffer structure, the telescopic support rod, the piston rod and the spring are four groups and have a symmetrical structure. Damping rubber is arranged around the piston rod, and the piston rod has a damping effect when moving inside the telescopic support rod.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. In the utility model, when the hydraulic buffer cavity is subjected to external force, the connector and the hydraulic buffer cavity are deformed, and the hydraulic oil flows accordingly to absorb the impact force. When the connector recovers its deformation, due to the high viscosity of the hydraulic oil, a damping effect is generated to delay the time for the connector to recover its deformation and protect the mainboard. There are 4 hydraulic buffer cavities, which are evenly distributed, and can buffer impact forces in multiple directions at the same time, thereby improving the buffering efficiency.

[0018] 2. In the utility model, when the telescopic support rod contracts, the spring is compressed. When the spring recovers its deformation, it pushes the piston rod to move inside the telescopic support rod. The damping layer can slow down the movement to avoid secondary shaking.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the utility model:

[0027] Reference Figure 1-5 A server anti-seismic motherboard structure includes a server chassis 1 and a motherboard 2. The motherboard 2 is installed inside the server chassis 1. Heat dissipation ports 101 are provided on both sides of the server chassis 1. Four corners of the motherboard 2 are integrated with mounting grooves 201. A heat dissipation fan is installed inside the heat dissipation port 101 to dissipate heat from the heating elements on the motherboard 2.

[0028] A buffer structure is provided at the bottom of the server chassis 1 to reduce the longitudinal vibration of the mainboard 2;

[0029] A supporting mechanism is provided inside the mounting groove 201 to reduce the impact force on the mainboard 2;

[0030] The buffer structure includes: a support seat 102, a connecting groove 103, a buffer head 1031, a telescopic support rod 3, a piston rod 301, and a spring 302. A support seat 102 is arranged at a position corresponding to the bottom of the server chassis 1 and the mounting groove 201. A buffer head 1031 is slidably arranged inside the support seat 102. The upper end of the buffer head 1031 is connected to the connecting groove 103, and the other end of the piston rod 301 is rotationally connected to the connecting groove 103. When the mainboard 2 applies longitudinal pressure to the connecting groove 103, the connecting groove 103 will move downward, thereby causing the buffer head 1031 to move longitudinally in the support seat 102. At this time, the telescopic support rod 3 contracts to achieve the purpose of buffering.

[0031] The bottom of the server chassis 1 is rotatably connected to the two sides of the support base 102 with a telescopic support rod 3, the interior of the telescopic support rod 3 is slidably connected to a piston rod 301, and the outside of the piston rod 301 is nested with a spring 302;

[0032] The supporting mechanism includes: a hydraulic buffer chamber 4, a connecting body 401, a shock-absorbing rubber seat 6, and a mounting hole 601. The shock-absorbing rubber seat 6 is threadedly connected to the mounting groove 201. The mounting hole 601 is installed inside the shock-absorbing rubber seat 6 through the hydraulic buffer chamber 4. The connecting body 401 is installed inside the hydraulic buffer chamber 4. The hydraulic buffer chamber 4 can weaken the impact force on the mainboard 2 at multiple angles.

[0033] Furthermore, the hydraulic buffer chamber 4 is made of rubber elastic material and hydraulic oil is arranged inside. The connecting body 401 is an elastomeric structure arranged back to back and made of PP plastic with the ability of deformation recovery. Its end is connected to the hydraulic buffer chamber 4. There are 4 hydraulic buffer chambers 4, which are evenly distributed around the mounting hole 601.

[0034] The connector 401 can provide support for the hydraulic buffer chamber 4. When the hydraulic buffer chamber 4 is subjected to external force, the connector 401 and the hydraulic buffer chamber 4 are deformed, and the hydraulic oil flows accordingly to absorb the impact force. When the connector 401 recovers its deformation, the hydraulic oil produces a damping effect, delaying the time for the connector 401 to recover its deformation and protecting the mainboard 2.

[0035] Furthermore, a stud 5 is threadedly connected inside the connection groove 103 , and the stud 5 passes through the mounting hole 601 .

[0036] Furthermore, in each group of buffer structures, the telescopic support rod 3, the piston rod 301, and the spring 302 are four groups and have a symmetrical structure. Damping rubber is arranged around the piston rod 301. The piston rod 301 has a damping effect when moving inside the telescopic support rod 3. When the telescopic support rod 3 contracts, the spring 302 is compressed. When the spring 302 recovers its deformation, it pushes the piston rod 301 to move inside the telescopic support rod 3. The damping layer can slow down the movement to avoid secondary shaking.

[0037] Working principle: First, put the mainboard 2 into the server case 1 so that the mounting hole 601 is aligned with the connecting groove 103, and the stud 5 is used to penetrate the mounting hole 601 and connect with the connecting groove 103, and the shock-absorbing rubber seat 6 is fixed, so that the mainboard 2 is fixed. Then, when the mainboard 2 is subjected to external vibration, when the connecting groove 103 is exerted with longitudinal pressure, the connecting groove 103 will move downward, so that the buffer head 1031 moves longitudinally in the support seat 102, and the telescopic support rod 3 contracts at this time to achieve the purpose of buffering. At this time, the spring 302 is compressed. When the spring 302 recovers its deformation, it will push the piston rod 301 to move inside the telescopic support rod 3, and the damping layer can slow down the movement;

[0038] Similarly, when the hydraulic buffer chamber 4 is subjected to external longitudinal or lateral pressure, the connector 401 and the hydraulic buffer chamber 4 are deformed, and the hydraulic oil flows accordingly to absorb the impact force. When the connector 401 recovers its deformation, the hydraulic oil produces a damping effect, delaying the time for the connector 401 to recover its deformation and protecting the mainboard 2.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
