Above-mentioned door anticollision crossbeam 10, reinforcement panel beating 200 is unanimous with the regional 120 molding of reinforcement, avoids traditional steel pipe and leg joint structure's door anticollision crossbeam, and the steel pipe can have the problem of machining precision error defect with the support in-process of independent machine-shaping separately, leads to the poor whole crashworthiness of influence of connection accuracy. The connection face of reinforcement panel beating 200 laminates completely on the regional 120 of reinforcement of main panel beating 100, and then has promoted the connection precision of reinforcement panel beating 200 with main panel beating 100, does not have the gap almost for connect the promotion of more firm intensity of being of value to. Door anticollision crossbeam 10 only carries out accurate reinforcement to the comparatively weak subregion of anti-collision performance, the regional original state that keeps that does not need anti-collision performance or has satisfied the performance, can make door anticollision crossbeam 10 wholly reach the requirement of anti-collision performance, the door anticollision crossbeam of comparing traditional single piece structure can only wholly increase the thickness of material or change the higher material of intensity, higher cost spending has not only been saved, the defect that the big or even difficult completion of technology degree of difficulty does not exist simultaneously, the problem of anti-collision performance and cost conflict mutually has been balanced betterly.
The main metal plate 100 is of a metal plate structure, one surface of the main metal plate 100 close to the vehicle seat is a first area 110, and the reinforcing area 120 is in the first area 110. The identification and division of the reinforced areas 120 in the first area 110 is primarily determined by crash performance requirements, which are the requirements for crash performance of the reinforced areas 120 beyond other locations of the first area 110, i.e., the reinforced areas 120 are more impacted in the event of a side impact. The anti-collision performance requirement can be evaluated through the vehicle door collision analysis result, and the region to be reinforced, namely the reinforcing region 120 with weak anti-collision performance can be determined after the vehicle door collision analysis is performed. The reinforcement panel beating 200 sets up in the reinforcement region 120 alright carry out accurate reinforcement with the reinforcement region 120 that the anti-collision performance is weak to main panel beating 100's bulk strength has been improved, and then the crashworthiness of improvement door anticollision crossbeam 10.
