The opening edge boss 4 is arranged in a ring shape, and is arranged on the inner side of the ring structure. The connection boss 5 is connected between the opening edge boss 4 and the ring structure.

[0043] The sunroof reinforcing ring structure provided by the above basic embodiment, the partial glue coating groove structure 2 is connected with the partial guide boss 3 to form a ring structure, the connecting boss 5 connects the ring-shaped opening edge boss 4 with the ring structure, which can provide multiple force transmission paths for the sunroof reinforcing ring structure, so that the stress borne by the sunroof reinforcing ring structure can be uniformly transmitted to the A-pillar, B-pillar and other areas with relatively large rigidity of the vehicle body, so as to ensure the structural stability of the sunroof installation, thereby improving the passenger comfort and improving the overall vehicle strength to provide certain protection for the passive safety of the passengers in the collision.

[0044] It should be noted that the glue coating groove structure 2 includes a glue coating groove located in the middle of the glue coating groove structure 2 and a boss feature surrounding the glue coating groove, so as to facilitate the process to identify the glue coating path and provide convenience for the glue coating design.

[0045] In some specific embodiments, the glue is extruded in the glue coating groove structure 2 to connect with the roof outer plate 12, specifically, the expansion glue can be used in the glue coating groove structure 2 to bond the roof outer plate 12, which increases the connection strength of the glue coating groove structure 2 and the roof outer plate 12 and supports the roof outer plate 12.

[0046] It should be noted that the front end of the reinforcing ring body 1 refers to the end of the reinforcing ring body 1 close to the front of the vehicle, the rear end of the reinforcing ring body 1 refers to the end of the reinforcing ring body 1 close to the rear of the vehicle, the left side of the reinforcing ring body 1 refers to the side of the reinforcing ring body 1 close to the main driver's seat of the vehicle, and the right side of the reinforcing ring body 1 refers to the side of the reinforcing ring body 1 close to the co-driver's seat of the vehicle.
