Top-cover outer plate and skylight reinforcing frame structure

A technology for strengthening frames and sunroofs, which is applied in the fields of car bodies and car sunroofs. It can solve the problems of affecting the NVH effect of the whole vehicle, the wear of the sealant strip, and the friction failure of the sheet metal, so as to improve the NVH performance, reduce the probability of wear and tear, and increase the connection. The effect of intensity

Problems solved by technology

It directly affects the NVH effect of the whole vehicle, and will also cause the friction between the two sheet metals to fail
[0009] 2. The top cover outer plate 1 and the skylight reinforcement frame 2 are at the vertical flange, and there is only one large surface that fits together. When this surface is welded by welding technology, the sheet metal at the welding point will be deformed, causing convex and concave points on the welding surface, and even Small burrs, when the sunroof opens and closes, the sealing strip rubs against the welding surface back and forth, eventually causing the sealing strip to wear out

Embodiment Construction

[0031] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.

[0032] Such as Figure 5 to Figure 8 As shown, a top cover outer panel 1 and a sunroof reinforcement frame structure 2 include a front reinforcement frame, a rear reinforcement frame and a left and right reinforcement frame;

[0033] In the front reinforcement frame, a gap of 3mm is designed between the outer plate of the top cover and the reinforcement frame of the skylight, and a 2mm glue groove is designed on the reinforcement frame of the skylight, and a shock-isolating glue 4 is arranged between the skylight and the glue groove. At the vertical flanges of the two panels, the skylight is provided with two surfaces in the shape of s...

Abstract

The invention relates to a top-cover outer plate and skylight reinforcing frame structure comprising a front reinforcing frame, a rear reinforcing frame, a left reinforcing frame and a right reinforcing frame. In the front reinforcing frame, the rear reinforcing frame, the left reinforcing frame and the right reinforcing frame, gaps are designed above a top-cover outer plate and a skylight reinforcing frame. By the top-cover outer plate and skylight reinforcing frame structure, abnormal sounds at the matching position of the front reinforcing frame due to metal-plate adhesion instead of connection are avoided; through the design of shock-insulating rubber, connection strength of two plates is improved; vehicle NVH (noise vibration and harshness) performance and vehicle quality are improved; through the design of two surfaces, width of the matching surface of a vertical turnup of the front reinforcing frame and a seal rubber strip is shortened, a welding matching surface and a seal rubber strip surface are separated, abrasion of the seal rubber strip surface is reduced, and accordingly, abrasion probability of the rubber strip is greatly reduced.

Description

technical field [0001] The invention belongs to the field of car bodies, refers to the field of automobile sunroofs, and particularly refers to a top cover outer panel and a sunroof reinforcing frame structure. Background technique [0002] The sunroof on the roof of the car is an important configuration in the process of car development. It can reflect the high-quality car riding environment and enhance the competitiveness of the car in the market. The design of the roof outer panel and the reinforcement frame of the sunroof is more important. A reasonable design of the roof outer panel and reinforcement frame can meet the installation strength of the skylight and the sealing of the sealing strip during the movement of the skylight. Satisfy the normal operation of the sunroof system during the vehicle reliability test. [0003] figure 1 It is a schematic diagram of the common structure of the outer panel of the roof cover and the reinforcement frame of the sunroof. The s...
