Tail door structure and vehicle

Abstract

The invention discloses a tail door structure and a vehicle. The structure comprises a tail door inner plate and a tail door outer plate which are connected with each other, a connecting piece is arranged at the bottom end of the tail door inner plate and comprises a first connecting plate and a second connecting plate which are connected with each other, and the end, away from the second connecting plate, of the first connecting plate is connected with the side end of the tail door inner plate. And the second connecting plate is connected with the tail door outer plate. According to the taildoor structure and the vehicle provided by the invention, the connecting piece is arranged between the tail door outer plate and the tail door inner plate, so that the static rigidity and the overallmode of the tail door structure are improved; thinning parts are arranged on the first connecting plate and / or the second connecting plate, so that when collision occurs, the connecting piece is disconnected along the thinning parts, the damage degree of the tail door inner plate is reduced, and the energy absorption effect is achieved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a tailgate structure and an automobile. Background technique [0002] At present, the tailgate structure of an automobile usually includes a tailgate inner panel and a tailgate outer panel. The tailgate inner panel and the tailgate outer panel are connected by gluing around the tailgate inner panel and the tailgate outer panel. A cavity is formed between the tailgate inner panel and the tailgate outer panel. area. Due to structural modeling, the distance between the tailgate outer panel and the tailgate inner panel is often too large in the cavity area, which will lead to a decrease in the overall mode of the tailgate structure and the static stiffness of this area. In order to meet the static stiffness and modal requirements, an adhesive connection structure is usually added in the cavity area. In the current common connection structure, the inner panel of the tailgate is bonded to t...
