Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model generally only has support main board for existing front door anti-collision rod after poppet, collision energy is just transmitted to lower end merely, and collision strength conduction pathway is few, and energy-absorbing position is not enough, well can not absorb the problem of collision energy, a kind of collision protection structure for arrangements for automotive doors is provided.
As shown in Figure 1, embodiment of the present utility model provides a kind of collision protection structure for arrangements for automotive doors, is made up of inner plate of car door 3, crash bar 1 and bracket assembly 2, and wherein crash bar 1 one end is fixed on inner plate of car door 3 by bracket assembly 2.The position of bracket assembly 2 on car door, it is positioned at car door posterior end, and between the inside and outside plate of car door, car load position is B post lower end is forward and rear wheel cover is anterior, and crash bar 1 and bracket assembly 2 pass through CO
2welding is formed, and entirety is welded on inner plate of car door 3 again.
As depicted in figs. 1 and 2, bracket assembly 2 is in L-type structure, comprise support mainboard 21 and support subplate 22, described support mainboard 21 is fixed by phase of solder joint with support subplate 22, described support mainboard 21 medium position is provided with the groove matched with crash bar 1, and described groove center is provided with the crash bar knock hole 5 for being positioned at crash bar 1 one end in groove.Described crash bar 1 both sides are fixed in groove by welding bar 7, and welding bar 7 is CO
2protection welding rod.
As shown in figures 1 and 3, support mainboard 21 side is provided with two support mainboard knock holees 4, described two support mainboard knock holees 4 lay respectively at groove both sides, described support subplate 22 one end is provided with support subplate knock hole 6, described support subplate knock hole 6 matches with one of them support subplate knock hole 4, and is together fixed on inner plate of car door 3 in support subplate 22 one end and support mainboard 21 by some solder joints.Support mainboard 21 is fixed on inner plate of car door 3 by some solder joints by support mainboard 21 another support mainboard knock hole location 4 on inner plate of car door 3.Mainboard knock hole 4 is concentric with subplate knock hole 6, and near knock hole, arrange the small size face of weld of fitting completely, ensures welding precision.
