Description

Technical Field

[0001] This utility model relates to the field of automotive injection molded parts, and in particular to a water-assisted molding plastic automotive dashboard bracket assembly. Background Technology

[0002] The car dashboard is a device that reflects the working status of various vehicle systems; common ones include fuel indicator lights, washer fluid indicator lights, electronic throttle indicator lights, front and rear fog light indicator lights, and warning lights. Furthermore, the car dashboard bracket beam structure is an essential component for fixing the car dashboard during the car assembly process.

[0003] Existing metal car dashboards have inherent manufacturing errors during installation and use. Although modern mechanical manufacturing technology has greatly improved and can keep part errors within a controllable range, given the tightness and fit of car assembly, and to avoid slight wear caused by errors during driving, the support frame can be improved to a micro-adjustable support frame. This allows the car dashboard to fit better into the car's instrument frame during assembly.

[0004] Meanwhile, existing instrument panel mounting bracket assemblies made of metal materials are integrally machined with the center console frame. When subjected to external impact, the center console frame, instrument panel mounting bracket, and related structures are easily damaged, requiring subsequent disassembly and maintenance. Depending on the severity of the damage, the entire assembly may need to be replaced, resulting in significant costs. Furthermore, the fixed structure of the instrument panel mounting bracket makes it inconvenient to disassemble and maintain when damaged. In addition, the traditional instrument panel bracket structure is complex, making disassembly, assembly, maintenance, and processing difficult and costly.

[0005] The dashboard bracket assembly, designed for lightweight and robust applications in new energy vehicles, is adapted to the overall design of new energy vehicles. Utility Model Content
