Abstract

The invention discloses a light-weight rear trunk separation plate used for a saloon car and a production process in the technical field of car trim. The light-weight rear trunk separation plate comprises a rear trunk separation plate assembly. The rear trunk separation plate assembly comprises a rear trunk separation plate assembly body, a rear car window frame outer plate, a rear car window frame fixing plate, a lower reinforcing plate, a front lower reinforcing plate and rear seat carrying hook supports. The rear end of the rear car window frame fixing plate is welded to the middle positionof the outer wall of the rear car window frame outer plate. Both the rear car window frame outer plate and the rear car window frame fixing plate are welded to the upper side of the rear end of the rear trunk separation plate assembly body. The lower reinforcing plate and the front lower reinforcing plate are welded to the left side and the front end below the rear trunk separation plate assemblybody respectively. A 340-590 MPa material with the thickness of 0.65 mm is adopted, the material specification is lowered but the strength is improved, the net weight of a product is reduced, the collision performance of a car body structural member is enhanced, the fuel performance index of the saloon car is reduced, and the safety of passengers is 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.
