AI Technical Summary

Technical Problem

The strength of the middle section of the roof assembly of MPV vehicles is poor, which causes the middle part of the roof to easily sink and deform, and the torsional stiffness and torsional mode values ​​of the vehicle body are low, and the ability to resist lateral collision deformation is poor.

Method used

A second reinforcement is provided in the top cover assembly, connected to the front edge of the second sunroof reinforcement plate, to enhance the strength and stiffness of the area between the first sunroof installation hole and the second sunroof installation hole, to prevent the area from deforming, and to prevent the top cover assembly from collapsed, squeezed and deforming into the car.

Benefits of technology

The strength and stiffness of the middle section of the top cover assembly are improved, the sinking deformation of the middle part of the top cover is prevented, and the torsional stiffness of the vehicle body and the ability to resist lateral collisions are enhanced, and the safety and NVH performance of the vehicle are improved.

Abstract

The utility model discloses a top cover assembly and a vehicle, and the top cover assembly comprises a top cover outer plate which is provided with a first skylight mounting hole and a second skylight mounting hole; the first skylight reinforcing plate is arranged around the edge of the first skylight mounting hole; a second sunroof reinforcing plate; the first reinforcing piece is arranged on the top cover outer plate and connected to the rear side edge of the first skylight reinforcing plate; the second reinforcing piece is arranged on the top cover outer plate and connected to the front side edge of the second skylight reinforcing plate. Therefore, the strength and rigidity of the area between the first skylight mounting hole and the second skylight mounting hole can be further improved, and the area between the first skylight mounting hole and the second skylight mounting hole can be prevented from deforming. The second reinforcing piece is connected to the front side edge of the second skylight reinforcing plate, supporting force can be provided for the front side edge of the second skylight reinforcing plate, and the top cover assembly can be prevented from collapsing, extruding and deforming towards the interior of the compartment.
