Abstract
The utility model discloses a door anti-collision device for an automobile. The door anti-collision device comprises a front door outer side reinforcing plate, a front door support reinforcing plate, a front door anti-collision bar, an anti-collision bar front support frame and an anti-collision bar back support frame, wherein the front door support reinforcing plate is connected and fixed with the front door outer side reinforcing and the front door anti-collision bar through screws to form a lattice-shaped structure. By the door anti-collision device disclosed by the utility model, the deformation quantity of an automobile door after the collision can be reduced to the greatest extent, the collision force is dispersed, and the harm to human bodies, caused by side-collision impact force, is retarded. The door anti-collision device has the advantages that during the side collision, the anti-collision bar is in a concave shape after the stress deformation, the stress points are dispersed, the impact fore is retarded, and the stress area is large, so the protecting space of the human bodies is enlarged; and after the stress, the deformation quantity of the door and door locks are small, and the rescue is convenient.
Description
Technical field
The utility model relates to a kind of car door parts, especially relates to a kind of vehicle door anti-collision device.
Background technology
Along with the development of automobile industry, people's attention is more and more received in the safety of auto against.Automobile is when receiving side and hit; Car door is received distortion easily, if the car door distortion is excessive, car door is too much to interior space invasion amount; Will serious threat arrive driver and passenger's life security; What at present door anti-collision joist adopted basically is parallel construction and " people " font structure, hits effect but all can't reach desirable anti-side, and the collision prevention girders that is arranged in the inner plate of car door middle part can't be protected occupant's position, thoracic cavity; In addition, car door is easy deformation at the door lock place, and car door can't be opened, and also has influence on occupant's escape.The utility model vehicle door anti-collision joist has adopted " well " font structure, collects the advantage of above-mentioned two kinds of structures, has reduced the deflection of bump tail gate to greatest extent, has disperseed impact, has slowed down the injury of side impact impulsive force to human body.
The utility model content
The utility model technical matters to be solved is: a kind of vehicle door anti-collision device is provided; It can improve the bulk strength and the rigidity of car door; Its energy-absorbing, power transmission are effective, and non-deformability is strong, helps protecting occupant's thoracic cavity and abdominal cavity; And protection car door door lock position, avoid because of being out of shape the excessive problem that can't open car door as far as possible.
The technical scheme of the utility model is following: a kind of vehicle door anti-collision device comprises Qianmen outer stiffening plate, Qianmen support reinforcing plate, front door anti-collision rod, crash bar front frame and crash bar after poppet; Said Qianmen support reinforcing plate connects fixedly Qianmen outer stiffening plate and front door anti-collision rod through screw, becomes " well " font structure, and all flatten at outer stiffening plate both ends, said Qianmen; Conveniently be fixedly connected on the arrangements for automotive doors inner panel; Said front door anti-collision rod is that pipe is processed, and two ends are provided with crash bar front frame and crash bar after poppet, and on body, is provided with two fasteners; Fastener is provided with screw, convenient fixedly Qianmen support reinforcing plate.
The beneficial effect of the utility model is: this mechanism when side impact, layer matrix behind the crash bar stress deformation, stress point disperses, and slows down impulsive force, area of thrust surface are big, thereby strengthened the guard space to human body; After stressed, the deflection of Door and its lock is little, is convenient to rescue.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the integral structure scheme drawing of the utility model.
Wherein: 1-Qianmen outer stiffening plate, 2-Qianmen support reinforcing plate, 3-front door anti-collision rod, 4-crash bar front frame, 5-crash bar after poppet.
The specific embodiment
A kind of vehicle door anti-collision device shown in Fig. 1-2; Comprise Qianmen outer stiffening plate 1, Qianmen support reinforcing plate 2, front door anti-collision rod 3, crash bar front frame 4, crash bar after poppet 5; Said Qianmen support reinforcing plate 2 connects fixedly Qianmen outer stiffening plate 1 and front door anti-collision rod 3 through screw, becomes " well " font structure.All flatten at outer stiffening plate 1 both ends, said Qianmen, conveniently is fixedly connected on the arrangements for automotive doors inner panel.Said front door anti-collision rod 3 is processed for pipe, and two ends are provided with crash bar front frame 4 and crash bar after poppet 5, and on body, are provided with two fasteners, and fastener is provided with screw, convenient fixedly Qianmen support reinforcing plate 2.
This new automobile door anti-collision joist has adopted " well " font structure, has reduced the deflection of bump tail gate to greatest extent, has disperseed impact, has slowed down the injury of side impact impulsive force to human body.This mechanism when side impact, layer matrix behind the crash bar stress deformation, stress point disperses, and slows down impulsive force, area of thrust surface are big, thereby strengthened the guard space to human body; After stressed, the deflection of Door and its lock is little, is convenient to rescue.
What should explain at last is: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification sheets has carried out detailed explanation to the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of impracticable later-model spirit and scope, all should be encompassed in the claim scope of the utility model.
