Description

Technical Field

[0001] The present invention relates to the technical field of chassis, and in particular to a universal sheet metal chassis for reducing static electricity generation. Background Art

[0002] In modern industrial environments densely populated with electronic equipment, electrostatic discharge (ESD) has become a key factor in equipment failure. Studies have shown that over 35% of electronic component failures can be traced back to ESD events. This is particularly true in areas where sheet metal chassis are widely used, such as servers, communication base stations, and industrial control equipment. The problems of circuit breakdown, signal interference, and data loss caused by static electricity are particularly prominent. Although international standards (such as IEC 61000-4-2) have clearly defined anti-static levels for electronic equipment, traditional sheet metal chassis designs still face multiple technical bottlenecks.

[0003] The existing Chinese patent with announcement number CN112272458B discloses a new sheet metal chassis, including a frame and a panel, the panel is spliced ​​together by several panel units, the panel unit includes a main panel, and the four sides of the main panel are respectively provided with side panels, two of which are connected to each other and provided with several card points, and the other two connected side panels are provided with several card slots, the card slots corresponding to the card points, and the card slots and card points are evenly spaced on the side panels, and the frame is provided with several square frames for installing panels, and two adjacent inner walls of the square frame are respectively provided with several card points, and the other two adjacent inner walls are respectively provided with several card slots.

[0004] The aforementioned patent and existing chassis easily generate heat during operation, which is difficult to dissipate. This causes the storage device to be affected by high temperatures, hindering its normal operation. Poor airflow can also lead to static electricity accumulation, reducing its service life. Furthermore, existing grounding systems have shortcomings: single-point grounding designs struggle to cope with complex electromagnetic environments, local potential differences lead to static electricity accumulation, and excessive grounding resistance (>10Ω) is common. The structural design is crude: air turbulence caused by the unreasonable layout of ventilation holes exacerbates surface charge separation, and the risk of sharp discharges at metal joints is not effectively suppressed.
