The door frame structure is generally composed of a notched underframe side beam, left and right door uprights and a top cover side beam, etc. The door corner, as an important component of the car body door frame, bears a large stress during the operation of the car body and is prone to stress concentration.

[0003] Publication No. CN 205292652 U discloses a rail vehicle car body door corner structure. The transition rib is integrally formed with the support part, so that the welding amount is small, the machining formability is good, the welding deformation is reduced, the strength reduction caused by the overlapping of welds at important positions is eliminated, the top surface of the transition rib forms a smooth transition, which is beneficial to the dissipation of stress and is more beautiful. The door corner structure and the door upright connection part are offset from the parallel weld by a certain distance, which disperses the stress. The door corner structure is simple, easy to process, widely adaptable, can shorten the production cycle, reduce manufacturing costs, and meet the aesthetic requirements. However, the patent still has the following problems in actual use:

[0004] Although the rail vehicle car body door corner structure integrally forms the transition rib with the support part, so that the welding amount is small, the machining formability is good, the welding deformation is reduced, the strength reduction caused by the overlapping of welds at important positions is eliminated, the top surface of the transition rib forms a smooth transition, which is beneficial to the dissipation of stress and is more beautiful, but when installing the door corner structure, the size of the door corner structure, the cross beam and the door upright needs to be fixed. When the size of the door upright and the cross beam changes, the door corner structure cannot be installed, resulting in poor applicability of the door corner structure. When there is a gap between the door corner structure and the door upright support, the gap cannot be automatically filled, affecting the support stability of the door corner structure.

[0005] Therefore, a rail car body door corner structure without welding structure is proposed to solve the problems mentioned above. UTILITY MODEL CONTENTS
