Abstract
The utility model discloses an automobile door anti-collision beam structure which comprises an anti-collision beam, a front fixing support and a rear fixing support. Two ends of the anti-collision beam are respectively welded and fixed with the front fixing support and the rear fixing support. The front fixing support and the rear fixing support are welded and fixed on an automobile door inner plate. The rear fixing support and the rear end of the anti-collision beam are welded and fixed at the rear end of the automobile door inner plate and correspond to the positions at the lower end of an automobile central upright so that an overlapped zone is formed. A middle section of the anti-collision beam is fixed with an automobile door outer plate through an automobile door outer plate reinforcing piece. The automobile door anti-collision beam structure can effectively reduce deforming intrusion of an automobile door towards the inner side of an automobile in collision and protect passengers inside the automobile well.
Description
Technical field
The utility model relates to automobile door structure, is specifically related to a kind of vehicle door anti-collision beam structure.
Background technology
Now, the safety performance to automobile requires more and more higher.Wherein, the car door anti-collision crossbeam is bigger to C-NCAP crash tests result's influence.When side collision took place, the car door anti-collision crossbeam can prevent car door excessive intrusion of direction in the car, with protection passenger safety.Each big car company has carried out in-depth study to the car door anti-collision beam structure when automobile is researched and developed, have than quantum jump at aspects such as crashproof beam structure, material, layouts, but when bumping, still there is deficiency in the ability of the resistance to deformation of existing car door anti-collision crossbeam.
Summary of the invention
The purpose of this utility model is to provide a kind of vehicle door anti-collision beam structure, and car door is invaded better protection passenger's safety to the distortion in the car in the time of can effectively reducing collision.
Vehicle door anti-collision beam structure described in the utility model, comprise crashproof crossbeam, preceding fixed support and back fixed support, the two ends of described crashproof crossbeam are fixing with preceding fixed support and back fixed support welding respectively, fixed support and back fixed support are weldingly fixed on the inner plate of car door before described, described back fixed support and crashproof crossbeam rear end are weldingly fixed on the inner plate of car door rear end, and it is corresponding with automobile central post lower end position, form the overlapping region, the stage casing of described crashproof crossbeam is fixed by door skin reinforcement and door skin.
Further, described crashproof crossbeam is made by high-frequency straight seam welded pipe.
Further, before described, all offer circular knock hole and bar shaped knock hole on fixed support and the back fixed support.
Further, fixed support and back fixed support are equipped with reinforced rib before described.
Vehicle door anti-collision beam structure described in the utility model; by the back fixed support of crashproof crossbeam being arranged in the overlapping region of inner plate of car door rear end and automobile central post; simultaneously that crashproof crossbeam and the welding of door skin reinforcement is fixing; make that this crashproof beam structure can be when bumping; farthest reduced car door and invaded to the distortion of car inside, protection passenger safety.And this crashproof crossbeam adopts high-frequency straight seam welded pipe to replace existing solid drawn pipe, has reduced cost under proof strength performance prerequisite; On the other hand, the design by reinforced rib on preceding fixed support and the back fixed support has further improved the ability of this crashproof beam structure resistance to deformation.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the preceding support bracket fastened axonometric drawing in the utility model;
Fig. 3 is the back support bracket fastened axonometric drawing in the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1, Fig. 2, vehicle door anti-collision beam structure shown in Figure 3, comprise crashproof crossbeam 2, preceding fixed support 1 and back fixed support 5, this crashproof crossbeam 2 is made by high-frequency straight seam welded pipe, high-frequency straight seam welded pipe is by the high tensile steel plate roll-forming, be welded through the high frequency vertical masonry joint again, tensile strength reaches more than the 1200MPa, fixed support 1 offers circular knock hole 12 and the bar shaped knock hole 13 for the welding location before described, be provided with reinforced rib 11 at this preceding fixed support, with support bracket fastened structural strength before the further raising; Equally, on the fixed support 5 of described back, all offer circular knock hole 52 and bar shaped knock hole 53, its with preceding fixed support on 1 knock hole realize cross bearing, with the raising welding precision, on this back fixed support 5, also be provided with reinforced rib 51; The two ends of described crashproof crossbeam 2 adopt the long carbon-dioxide arc welding of six sections 12mm and preceding fixed support 1 and 5 welding of back fixed support fixing respectively; fixed support 1 and back fixed support 5 all are weldingly fixed on the inner plate of car door 4 by three solder joints before described; back fixed support 5 and crashproof crossbeam 2 rear ends are weldingly fixed on inner plate of car door 4 rear ends; and it is corresponding with automobile central post lower end position; form the overlapping region; preceding fixed support 1 is welded on inner plate of car door 4 front portions and is higher than the back fixed support, and the stage casing of this crashproof crossbeam 2 is fixed by door skin reinforcement 3 and door skin.
