AI Technical Summary
The existing car roof beam connecting plate is prone to deformation or breakage when subjected to impact, resulting in safety hazards that are difficult to detect in time, especially posing a significant risk in incidents of falling objects from heights.
A car roof beam connecting plate is designed, including an integrally connected upper connecting part and a side connecting part, with a force-bearing buffer part and a buffer spring. The impact force is absorbed by the bending structure and the buffer spring, which enhances the impact resistance of the connecting plate. The structural strength and durability are improved by welding and anti-corrosion film.
It effectively reduces the probability of deformation or breakage of the connecting plate during impact, ensures the integrity of the vehicle body connection structure, improves safety and service life, avoids safety hazards, and extends the service life of the connecting plate.

Abstract
Claims
1. A car roof crossbeam connecting plate, comprising an integrally connected upper connecting part (1) and a side connecting part (2), wherein the upper connecting part (1) is fixedly connected to the car roof crossbeam by screws, and the side connecting part (2) is fixedly connected to the car body pillar by screws, characterized in that: The free end of the upper connecting part (1) is bent inward to form a force-bearing buffer part (3). A buffer spring (4) is fixedly connected to the force-bearing buffer part (3). The top of the buffer spring (4) abuts against the bottom surface of the upper connecting part (1).
2. A roof cross rail connector panel for a vehicle as defined in claim 1, characterized in that: The force-bearing buffer section (3) includes a lower fold section (31) and a return section (32). The return section (32) is parallel to the upper connecting section (1). The vertical distance between the return section (32) and the upper connecting section (1) is less than the length of the side connecting section (2) in the vertical direction. The return section (32) is also provided with a fixing screw hole (33). The buffer spring (4) is fixed on the return section (32).
3. A roof header tie plate for a motor vehicle as defined in claim 2 wherein: The lower fold section (31) is fixedly connected to the side of the car roof beam. The lower fold section (31) includes a first bend (311), a second bend (312) and a third bend (313) connected in sequence. The first bend (311) is connected to the upper connecting part (1), and the third bend (313) is connected to the return bend section (32). The first bend (311) and the third bend (313) protrude in the direction away from the side connecting part (2), and the second bend (312) protrudes in the direction close to the side connecting part (2).
4. A roof header tie plate for a motor vehicle as defined in claim 2, wherein: The buffer spring (4) includes an M-shaped body (41), the top of which abuts against the upper connecting part (1), and the two ends of the body (41) are bent to form a recess (42), the end of which is downward and fixedly connected to the return section (32).
5. A roof header tie plate for a motor vehicle as defined in claim 4 wherein: The main body (41) is also provided with support sections (43) on both sides. The ends of the two support sections (43) intersect and are simultaneously fixedly connected to the bend section (32).
6. A roof header tie plate for a vehicle as defined in claim 1, wherein: The upper connecting part (1) and the side connecting part (2) are provided with reinforcing parts (5) formed by stamping.
7. A roof header tie plate for a vehicle as defined in claim 1, wherein: The upper connecting part (1) and the side connecting part (2) are also provided with welding parts (6).
8. A roof header tie plate for a vehicle as defined in claim 1, wherein: The surfaces of the upper connecting part (1) and the side connecting part (2) are covered with an anti-corrosion film.
