Description

Technical Field

[0001] This utility model belongs to the field of vehicle body structure, and more specifically, it relates to a novel connection structure for the rear crossbeam joint area of ​​the roof. Background Technology

[0002] As people's living standards continue to improve, their demands for automobiles are also increasing. Safety, as the most basic indicator for evaluating a vehicle's quality, receives particular attention. The rear crossbeam joint area of ​​the roof is responsible for the connection and stress distribution between the rear crossbeam and the side panel. Its structural form and connection method play a crucial role in the torsional rigidity of the vehicle body. Therefore, the design of the component connection structure in the rear crossbeam joint area is extremely important in vehicle body design. The existing connection structure in the rear crossbeam joint area mainly consists of the rear crossbeam, side panel drainage channels, side panel outer panels, and the D-pillar reinforcement plate. There is no direct connection at the joint area; the connection relies on the D-pillar reinforcement plate.

[0003] The existing connection structure for the rear crossbeam joint area of ​​the roof relies on the reinforcing plate on the D-pillar to connect the rear crossbeam, the D-pillar drainage channel, and the outer side panel. This structure and connection method have two problems: 1. For passenger safety, the rear crossbeam connecting plate of the roof and the reinforcement plate on the D-pillar are usually made of high-strength steel plates. Furthermore, because some models only have the lower plate of the rear crossbeam, the steel plate in these areas is thicker than in other areas. With societal development, to adapt to more complex working conditions, the requirements for the vehicle's bending and torsional performance are becoming increasingly stringent.

[0004] 2. The existing structural joint area is not a complete whole. The force transmitted from the rear crossbeam of the roof to the side panels and D-pillar drainage channels is limited, the force transmission channel is not smooth, and the structural rigidity is weak. This results in a poor improvement in the vehicle's bending and torsional performance. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a new type of connection structure for the rear crossbeam joint area of ​​the roof. By setting a connecting plate for the rear crossbeam of the roof, the structure at the joint position of the rear crossbeam of the roof is reintegrated into a single part, thereby improving the bending and torsional performance of the vehicle body and enabling the whole vehicle to better adapt to complex working conditions.

[0006] The novel connection structure for the rear crossbeam joint area of ​​the roof includes an outer side panel, a D-pillar drainage channel plate, an upper plate for the rear crossbeam of the roof, and an upper reinforcing plate for the D-pillar. It also includes a connecting plate for the rear crossbeam of the roof. A first connecting part is fixedly provided on the inner side of the connecting plate, with its top fixedly connected to the upper plate for the rear crossbeam of the roof. A second connecting part is fixedly provided on the front side of the connecting plate, with its bottom fixedly connected to the upper reinforcing plate for the D-pillar. A third connecting part is fixedly provided on the outer side of the connecting plate, with its bottom fixedly connected to the outer side panel. A fourth connecting part is fixedly provided on the rear side of the connecting plate, with its bottom fixedly connected to the drainage channel plate for the D-pillar. A glue-applying groove is fixedly provided in the middle of the connecting plate. A positioning hole and a weight-reducing hole are also fixedly provided in the middle of the connecting plate. Decorative panels extend outward from both the third and fourth connecting parts.

[0007] Preferably, a pre-fastener is fixedly connected to the first connecting part, and a welding mating surface is fixedly connected to the rear part of the first connecting part.

[0008] Preferably, the second connecting part is fixedly provided with a first folded edge, the third connecting part is fixedly provided with a second folded edge, and the third connecting part is fixedly provided with multiple sets of electrophoresis holes.

[0009] Preferably, a waterproof adhesive strip mounting hole is fixedly provided on the fourth connecting part.

[0010] Preferably, the decorative panel extends upward with a flange.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting the rear crossbeam connecting plate of the roof, the structure of the rear crossbeam joint of the roof is re-integrated into a single part, changing the original part overlapping form, improving the bending and torsional performance of the vehicle body, and allowing the whole vehicle to better adapt to complex working conditions; at the same time, by setting the rear crossbeam connecting plate of the roof, a smooth transition from the outer panel of the roof side panel to the D-pillar water channel plate is achieved, giving the whole vehicle a better visual effect. 2. By setting fold one and fold two, the contact area and welding area between the top cover rear beam connecting plate and the D-column upper reinforcing plate and the side outer plate are increased, thereby improving the connection strength. At the same time, the structural strength of the second and third connecting parts is improved by setting the bending. Attached Figure Description

A glue-applying groove 9 is fixedly provided in the middle of the rear crossbeam connecting plate 5 of the roof. The glue-applying groove 9 is a groove structure specifically used to accommodate sealant / structural adhesive, filling the contact surface between the rear crossbeam of the roof and the car body to improve the connection strength.

[0017] The top cover rear crossbeam connecting plate 5 is also fixedly provided with positioning holes 8 and weight reduction holes 10. The positioning holes 8 are used to assist in the positioning of various structural components to ensure accurate installation. The weight reduction holes 10 can reduce the weight of the vehicle body to a certain extent, improve the overall vehicle energy efficiency, optimize performance, disperse stress, and avoid cracking caused by excessive local stress. The third connecting part 503 and the fourth connecting part 504 both have decorative panels 505 extending outward.
