Abstract

The present invention belongs to the technical field of an automobile structure, and particularly relates to a back door and an automobile; the back door includes a back door inner panel and a back door outer panel; the back door inner panel and the back door outer panel are fixedly connected to form the back door; the back door outer panel is provided with a first lug boss protruding toward the back door inner panel, and the back door inner panel is provided with a second lug boss protruding toward the back door outer panel; and the top surface of the first lug boss is in abutment with that of the second lug boss so as to form a tail light installation part for installing a tail light at the abutment position of the first lug boss and the second lug boss. By using a back door structure provided by the present invention, the material thickness and local stiffness at an installation position are effectively improved, thereby ensuring the installation stability of the tail light and being beneficial to the weight and consumption reduction of an automobile body.

Description

technical field [0001] The invention belongs to the technical field of automobile structure, and in particular relates to a back door and an automobile. Background technique [0002] Most of the car back doors commonly seen in the market are steel back doors, and most of them do not have the problem of insufficient local rigidity at the taillight installation point. With the increasing pressure of weight reduction and consumption reduction, lightweight is the current trend of vehicle development, and plastic back doors are one direction for body weight reduction. The outer panel of the plastic back door is mostly made of PP material with good surface quality and light weight, but its own rigidity is low. [0003] The plastic back door structure of the existing car includes the inner panel of the back door and the outer panel of the back door. The conventional taillight installation method is to directly install the taillight on the outer panel of the back door. The difficu...
