Outline
Currently, internal components of automotive lamps are primarily secured by methods such as snap-fit or mechanical fastening. However, snap-fit assemblies carry risks of material embrittlement and fracture, while mechanical fastening structures require reserved space for screw holes, leading to inefficient space utilization. These issues constrain the improvement of weight reduction and reliability in automotive lamps. To address these challenges, this paper proposes an adhesive bonding solution for lamp components based on ultraviolet (UV) -curable adhesive. Tests were conducted on the tensile strength, moisture resistance, high-temperature resistance, and thermal cycling performance of different adhesive materials, as well as the reinforcing effect of plasma treatment on the bonding interface. The test results indicate that UV adhesive can achieve a bonding strength of approximately 10 MPa when bonding plastic parts, demonstrating certain engineering feasibility. This provides a new technical pathway for upgrading automotive lamp manufacturing processes.
