Problems solved by technology

However, the increase in material specifications leads to an increase in the weight of the parts, which increases the weight of the vehicle, the lightweight of the vehicle cannot be guaranteed, and the fuel consumption of the vehicle increases.
[0004] The structural design of high-strength thin plates instead of ordinary thick plates is at the leading level, and the split welding structure of high-strength stamped trunk partitions has not yet been implemented by other domestic competitors

Abstract

The invention discloses a lightweight rear trunk partition for a car in the technical field of vehicle interior decoration and a production process, including a rear trunk partition assembly, and the rear trunk partition assembly includes a rear trunk partition assembly , rear window frame outer plate, rear window frame fixing plate, lower reinforcement plate, front lower reinforcement plate and rear seat bracket, the rear end of the rear window frame fixing plate is welded to the rear window frame outer plate In the middle of the outer wall, the rear window frame outer plate and the rear window frame fixing plate are welded to the rear upper side of the rear trunk bulkhead assembly, and the lower reinforcement plate and front lower reinforcement plate are respectively welded to the rear trunk bulkhead assembly. The lower left side and the lower front end are made of 0.65mm 340~590MPa material, the material specification is reduced but the strength is enhanced, the net weight of the product is reduced, the collision performance of the body structure is enhanced, the fuel efficiency index of the car is reduced, and the passenger safety can be further guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle interior decoration, in particular to a lightweight rear trunk partition for a car and a production process. Background technique [0002] Existing passenger car trunk partitions are plates arranged between the rear seats of the car and the trunk, mainly to isolate luggage and other sundries from the space where people ride. [0003] In the usual body design, the body parts of the trunk partition are integrated, and the design strength of the trunk partition is 130-260MPa. The current trunk partition is analyzed from the structural shape, and the material specification of the trunk partition body is 0.8mm. ~1.0mm to enhance crash performance. However, the increase in material specifications leads to an increase in the weight of the parts, which increases the weight of the vehicle, the lightweight of the vehicle cannot be guaranteed, and the fuel consumption of the vehicle increases. [0004] The...
