AI Technical Summary
Technical Problem
Existing high-frequency switching power supplies are unable to meet the anti-vibration requirements under high vibration conditions, and adding additional anti-vibration measures will affect the heat dissipation effect.
Method used
A shock-resistant structure for a high-frequency switching power supply box is designed, which uses buffer columns and elastic sheets to form a multi-level shock-resistant structure, and increases the heat dissipation path by using heat-conducting strips inside the hollow buffer columns.
Benefits of technology
To ensure the safe operation of electrical components under strong vibrations, reduce the risk of electrical short circuits, and maintain good heat dissipation efficiency.

Abstract
This utility model discloses a shock-resistant structure for a high-frequency switching power supply box, comprising a power supply box with an internal circuit board and electrical components. The bottom and perimeter of the power supply box are provided with support plates. Multiple buffer mechanisms are installed on the side of the support plates facing the power supply box. Each buffer mechanism includes buffer columns with both ends connected and fixed to the power supply box and the support plates, respectively. The buffer columns are elastic and can expand and contract. Multiple elastic sheets are fixedly installed around the circuit board inside the power supply box, with the bottom and perimeter of the circuit board connected and fixed to the elastic sheets. This high-frequency switching power supply box shock-resistant structure, through the buffer columns and elastic sheets forming a multi-level shock-resistant structure, ensures the safe operation of electrical components even under significant vibrations, reducing electrical short circuits and safety hazards caused by vibration.
