The invention provides a stopper and a folding wingtip stopping structure, relates to the technical field of aircraft structure design, can realize impact load buffering and secondary stopping when a folding wingtip is opened to a corresponding position, and can also give an electric signal to guide the locking action according to the stopping condition. The stopper comprises a body structure and a stop opening cover, and during stop, the stop opening cover is connected to the body structure in a covering mode to achieve stop. The body structure comprises an elastic part and a non-elastic part, the elastic part is used for buffering an impact load transmitted from the stop covering cap during stop, and the non-elastic part is used for realizing final stop positioning; the non-elastic part is a hollow structure shell with an opening at one end, and the elastic part is arranged in the shell; the stop opening cover comprises a contact layer and a stop layer; the contact layer and the elastic part realize contact and compression, and the stop layer is in stop connection with the shell; the elastic part comprises a piezoelectric layer and is connected with external equipment through a signal line. The technical scheme provided by the invention is suitable for the stop process of the folding wingtip.
