Furthermore, the upper and lower door frames are respectively positioned on the same curve with the aluminum section beam columns arranged along the vehicle length direction in the side wall framework, so as to play a role of connecting the beam columns at two sides, transfer load, be beneficial to the conduction and distribution of energy, avoid stress concentration and ensure the strength of the vehicle head structure,
furthermore, in the left and right door frames, the width of the right door frame is larger than that of the left door frame, so that the whole door frame is borne when a load is applied to the left and right door frames, and the load is continuously transmitted backwards.
Furthermore, the welding seams of the four door frames are staggered from the side wall framework, the aluminum profile beam columns are arranged along the vehicle length direction, stress concentration is avoided, and strength is reduced.
The invention has the following advantages:
1. the door frame is formed by welding high-strength aluminum alloy plates, has high strength, is connected with the original beam column by utilizing the self cross beams of the upper door frame and the lower door frame when being welded with the side wall, and keeps the arrangement form of the original beam column as far as possible, so that the load transmission mode is similar to the original structure, and the door frame is added on the side wall, but the strength of the vehicle body can still meet the requirements of relevant standards.
2. According to the designed position of the door frame, a part with a smooth arc-shaped head is selected, and a groove is formed in the welding position of the top of the door frame and the skin, so that the original skin ridge line is not damaged. The device not only can ensure the net passing width and height of the door, but also can ensure that the device is simple and convenient to mount when a vehicle is parked, can be well shaped along with the vehicle head without excessive adjustment, does not influence the attractiveness, and realizes the function.

Detailed Description
In the invention, the running direction of the train is front, so the left side of the aluminum structure of the train head is front, and the right side is back.
Referring to fig. 1 and 2, the boarding door frame is manufactured by a high-strength aluminum alloy plate machining method, is divided into an upper door frame 1, a lower door frame 3, a left door frame 6 and a right door frame 4, is connected by welding, is machined again to ensure the accuracy after being welded, and is welded with a frame of a side wall of a vehicle head as a whole to complete assembly. The upper and lower door frame is the high strength aluminum alloy plate of both ends form of bending, and the upper and lower door frame links up both sides beam column through the welding, simultaneously with the left and right sides door frame welding together, adopts the form of bending, and two kinds of welding seams can not be in upper and lower door frame both ends gathering, avoid stress concentration at same position, can guarantee the intensity of structure. And in order to guarantee the shape along with the locomotive, the upper and lower door frames all have the curved line molding in the length of a car and two dimensions of car width, adopt bending structure, can arrange the welding seam between upper and lower door frame and left and right sides door frame on the door frame about nearly vertical, avoid the welding seam to bear the stress on the length of a car and two dimensions of car width simultaneously, improve the intensity of door frame. Step on door left and right sides door frame and be 120mm wide and 200mm wide high strength aluminum alloy plate respectively, when side wall aluminium alloy beam column transmission load was located to 120mm wide left side door frame, high strength aluminum alloy plate has sufficient intensity, can bear the load and pass through the right door frame transmission of upper and lower door frame to the rear side, the right door frame of rear side adopts the wide high strength aluminum alloy plate of 200mm, bigger width's aluminum alloy plate, can play the effect of bearing whole door frame when receiving the load, and continue the backward transmission with the load.
Referring to fig. 3, 4 and 5, when the integral door frame is welded with the underframe, the connecting area at the bottom of the lower door frame 3 is processed into a beam column form, so that the existing car is guaranteed to be researched and assembled during welding. When the left and right door frames are welded with the side walls, the long round holes 5 are additionally formed in the door frames, so that the phenomenon of weld joint impermeability caused by over-thick door frames is avoided when the side walls are connected with the side wall beam columns. When the door frame and the top are welded, the original ridge skin is reserved and welded on the door frame, the welding groove is formed in the door frame, and meanwhile, the upper door frame 1 is welded with the side wall beam column, so that the strength of the whole side wall is guaranteed. Through the scheme, the whole door frame is welded with the frame of the side wall of the vehicle head, and the assembly is completed, so that the strength can be guaranteed, and the feasibility of actual operation can be guaranteed.
Referring to fig. 6, the upper and lower door frames are respectively positioned on the same curve with arrows on the aluminum section beam columns 7 and 8 arranged along the vehicle length direction in the side wall framework, so that the function of connecting the beam columns on the two sides is achieved, the load transmitted from one end can be transmitted backwards through the upper and lower door frames according to the direction indication of the arrows, the energy conduction distribution is facilitated, the stress concentration is avoided, and the strength of the vehicle head structure is ensured. The aluminum profile beam columns distributed in the side wall framework along the vehicle length direction are staggered at the welding seams of the four door frames, so that stress concentration is avoided, and the strength is reduced.
Referring to fig. 7, the left and right door frames of the boarding door are thick high-strength aluminum alloy plates, the beam columns on the two sides are connected with the door frame into a whole, the effect of supporting the beam columns on the two sides is achieved, and the left and right door frames can be guaranteed not to be damaged when bearing loads transmitted by the beam columns on the two sides.
