Abstract
The utility model discloses a novel anti-collision beam of a car door. The anti-collision beam of the car door is made of a cold-rolled super-strength steel tube with a hot stamping forming technology. According to the anti-collision beam of the car door, weight is reduced, crashworthiness of sides of a car is improved, all safety indexes are improved, processes are reduced due to the elimination of connecting supports at two ends, light weight superiority is obvious, economic effectiveness is prominent, cost is reduced, and resources are saved.
Description
Technical field
The utility model relates to auto parts and components, is specifically a kind ofly can realize lightweight, can improve again the Novel car door collision prevention girders of structural strength.
Background technology
Automobile side is the weak position of intensity in the car body, and door anti-collision joist is that fore-and-aft direction adds entablatrance on inner plate of car door as a kind of extra energy-absorbing fender guard, in order to strengthen the rigidity of car door.Optimize the collision prevention girders structure, improve its intensity, improve automotive side face collision safety, will improve occupant's safety precaution.
The vehicle door anti-collision joist general section is circle, single shape for hat or " W " " M " type, collision prevention girders is tubular described in the patent No. 200920206636.6 inventions, the patent of patent 201120253687.1,201210037362.9 all discloses a kind of automobile buffer beam.These collision prevention girders adopt cold shaping or rolling forming more, and intensity is not high, can't solve the collision prevention girders problem that load is transmitted in collision process, and using the superhigh intensity door anti-collision joist is developing direction.The ultra-high-tensile steel heat-punch member can reach the above intensity of 1500MPa, and forming accuracy is high, can greatly improve car door anti-collision intensity, improves automotive side face collision safety, and the consumption in the vehicle manufacture has significantly year by year to be increased.
Summary of the invention
The purpose of this utility model provides a kind of vehicle door anti-collision joist in order to overcome the deficiency of above-mentioned background technology, and the utility model can significantly alleviate the overall weight of vehicle door anti-collision joist, reaches the purpose of body lightening; Promote automotive side face collision safety, every safety index all increases.Collision prevention girders described in the utility model can absorb energy in the side collision process, transfer loads to simultaneously B post and vehicle body, thus passenger's safety in the protection car.The advantage of the compatible prior art of the utility model has promoted the passive security performance of Integral automobile.
Technical purpose of the present utility model mainly is to be achieved by following technical proposals.
A kind of vehicle door anti-collision joist that the utility model provides is made by cold roll forming super-high strength steel steel pipe, and described door anti-collision joist adopts hot stamping method to be shaped.
In technique scheme, described beam body section be "
" font.
In technique scheme, cross section, described beam body middle part opening angle is 80 ° ~ 95 °.
In technique scheme, the end cross-sectional opening degree of described vehicle door anti-collision joist is 95 ° ~ 120 °.

In technique scheme, centre portion and the two end portions of described vehicle door anti-collision joist seamlessly transit.
Vehicle door anti-collision joist of the present utility model has following beneficial effect: adopt heat forming technology to process so that strength of material promotes, structure optimization be "
" font, crashworthiness optimization; Adopt "
" font, the connection bracket at cancellation two ends is saved operation, is convenient to the welding of door anti-collision joist and automobile door structure; Lightweight is with the obvious advantage, and economic benefit is outstanding; Cost, saving resource.
Description of drawings
Fig. 1 is vehicle door anti-collision joist structural representation of the present utility model.
Fig. 2 is the A-A face cutaway view of Fig. 1.
Fig. 3 is the B-B face cutaway view of Fig. 1.
The specific embodiment
The utility model is a kind of vehicle door anti-collision joist, its cross section be "
" font structure, door anti-collision joist adopts the super-high strength steel steel pipe through hot press-formed manufacturing process, has good dimensional accuracy and very high intensity, and has good bending resistance, adopt simultaneously "
" cross section of font, whole collision prevention girders energy-absorbing effect in collision process is better.
The below further explains the utility model with reference to the accompanying drawings.
As shown in Figure 1, a kind of vehicle door anti-collision joist, adopting the external diameter of super-high strength steel steel pipe is 50 ~ 60mm, wall thickness is 1.0 ~ 2.0mm, forms through drop stamping.Beam body middle part opening angle is 80 ° ~ 95 °, and beam end of body opening degree is 95 ° ~ 120 °, and stretching depth is 30 ~ 35mm.
Door anti-collision joist of the present utility model is compared with existing door anti-collision joist, has following advantage:
Alleviate pts wt, economical with materials, with the weight reducing of vehicle door anti-collision joist more than 20%, reduce production costs; Increase the intensity of part, satisfy automobile side crash standard GB20071-2006, guarantee occupant safety; Reduce the connection bracket at two ends, saved cost and operation.
The utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasions, all within protection domain of the present utility model.
