Connection structure for automobile parts and production method of connection structure

Abstract

The invention provides a connection structure of automobile parts, which comprises a first connecting piece and a second connecting piece which is glued to the first connecting piece, and the first connecting piece and the second connecting piece are made of carbon fiber composite material. The automobile parts connecting structure of the present invention connects two connecting pieces by glue connection to form an effective high-strength and low-quality carbon fiber connecting structure, which not only improves the connection efficiency, but also improves the connection durability, and can reduce or eliminate the common Surface delamination and shear failure, which often occur in joints, can result in better joint strength. The invention also provides a manufacturing method of the automobile component connection structure and an electric automobile floor assembly.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular, the invention relates to an auto part connection structure and a manufacturing method thereof. Background technique [0002] Automobile lightweight technology is one of the effective technical ways to save energy consumption and reduce environmental pollution for new energy vehicles and traditional internal combustion engine vehicles. Authoritative research shows that if the weight of the vehicle is reduced by 10%, the fuel efficiency can be increased by 6%-8%; for every 100 kg of vehicle curb weight reduction, the fuel consumption per 100 kilometers can be reduced by 0.3-0.6 liters. From the perspective of driving performance and collision safety, after the car is lightweight, the acceleration is improved, the braking distance is reduced, the inertia of the collision is reduced, and the vehicle control sensitivity, stability, noise and vibration are also improved. In recent ye...

AI Technical Summary

Problems solved by technology

[0003] With the increasing application of automotive carbon fiber composite materials, the problems of combined assembly between automotive composite material parts and the connection and fastening between carbon fiber composite material parts and adjacent parts have become increasingly prominent. Traditional metal parts in the automotive industry The connection method can no longer meet the needs of objective applications

However, the connection structure made of carbon fiber composite materials in the prior art still has the defects of surface delamination and shear failure, and the connection strength is poor.
