technical field

The present application relates to the technical field of passenger car body manufacturing, and in particular, to a connection structure between a sunroof reinforcement ring and a body.

Background technique

With the increase of automotive application scenarios, people stay in the car for longer and longer. The skylight has become one of the important configurations due to its lighting performance and ventilation function. Car sunroofs can be divided into two types: panoramic sunroofs (sky curtains) that cannot be opened by glass and sunroofs that can be opened by glass. The panoramic sunroof (sky screen) adopts an integral glass roof and does not have ventilation function.

As shown in Figure 1, the sunroof glass is located in the blank space in the middle of the roof. The surrounding of the sunroof glass needs to have an openable sealing structure with the metal structure of the vehicle body, and the opening mechanism of the sunroof is installed under the sunroof reinforcement ring in a ring structure. The sunroof reinforcement ring has a hollow annular body piece, three brackets connected to the front cross member of the top cover, two brackets connected to the left side wall, and two brackets connected to the right side wall, at the rear of the sunroof reinforcement ring Has a roof center beam.

The skylight reinforcement ring is formed by blanking a rectangular sheet. The rectangular part in the middle of the part corresponds to the skylight glass. The material of this part will be wasted as waste, resulting in a very low material utilization rate and an increase in the cost of the parts. At the same time, the sunroof reinforcement ring is welded and connected to the body by the above-mentioned seven brackets. Due to the tolerance of the parts and the influence of welding tolerance, the position of these seven brackets with the front beam of the roof and the fitting surfaces of the left and right side walls is not stable. As a result, the relative accuracy of the sunroof reinforcement ring and the vehicle body is out of tolerance, or the connection strength between the sunroof reinforcement ring and the vehicle body is reduced.

The sunroof glass cooperates with the top cover through the surrounding sealing strips to achieve waterproof sealing. If the relative accuracy of the sunroof reinforcement ring and the body is too poor, the gap between the sunroof and the top cover will be poor, resulting in appearance defects and serious wind noise. , causing the sunroof to leak. If the connection strength between the sunroof reinforcement ring and the body is reduced, it will reduce the transmission of the vehicle's response to roof pressure and side impact energy, resulting in a safety risk.
