Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a universal gas cylinder support bracket and forming mold. Background Technology

[0002] Existing gas cylinder brackets employ a back-attached design, meaning the bracket is welded to the main structure. This design leads to stress concentration on one side of the main column, easily generating fatigue stress and reducing the bracket's stability and lifespan. Furthermore, back-attached brackets rely on multi-point welding assembly, a cumbersome process that increases production costs and time, and introduces safety hazards due to the vulnerability of weld points to cracking. With increasing demands for lightweight and reliable vehicles, existing brackets perform poorly under dynamic loads, necessitating a structurally optimized and efficiently formed solution. Utility Model Content
