Abstract
The invention discloses an anti-collision beam for an automobile door. The front end of the anti-collision beam for the automobile door is fixed in a position close to the bottom of a pillar A while the rear end is fixed in the position on an inner plate of the automobile door and close to the lower end of a pillar B and a pedal of the automobile door. The anti-collision beam for the automobile door is provided with a V-shaped cross section and is subjected to heat forming technology, so that the strength is increased, the anti-collision property is optimized, the connecting brackets at two ends are omitted, the process is saved and the light-weight effect is obvious. The width of a pressing edge on an end part of the anti-collision beam for the automobile door is more than the width of the middle part, so that the anti-collision beam can be conveniently welded with the automobile door.
Description
Technical field
The present invention relates to auto parts and components, specifically, the present invention relates to a kind of vehicle door anti-collision joist.
Background technology
Along with automobile pollution increases severely, traffic accident is ascendant trend significantly, and wherein the side impact accident occupies the first place of urban traffic accident, and the personal casualty number that causes accounts for 30.1% of the total casualties of car accedent.Automotive side face collision safety property is one of automobile vehicle performance index of paramount importance; Side space is narrow; Be unfavorable for relating to labyrinth with the absorbing impact energy, automobile side is the weak position of intensity in the car body, and door anti-collision joist is as a kind of extra energy-absorbing fender guard; Be that fore-and-aft direction adds entablatrance on inner plate of car door, in order to strengthen the rigidity of car door.Optimize the collision prevention girders structure, improve its intensity, improve automotive side face collision safety property, the safety precaution that improves the occupant.
The vehicle door anti-collision joist general section is perhaps " W " " M " type of circle, single shape for hat; Collision prevention girders is a tubular described in the patent No. 200920206636.6 inventions, and patent 201120253687.1 and 201210037362.9 all discloses a kind of vehicle door anti-collision joist.These collision prevention girders adopt cold shaping or rolling forming more, and intensity is not high, can't solve the problem of collision prevention girders loading transfer in collision process.The ultra-high-tensile steel heat-punch member can reach the above intensity of 1500MPa, and forming accuracy is high, can improve car door anti-collision intensity greatly, improves automotive side face collision safety property, and the consumption in the vehicle manufacture has significantly year by year to be increased.
Summary of the invention
Technical matters to be solved by this invention provides a kind of vehicle door anti-collision joist, and said collision prevention girders can absorb energy in the side collision process, and transfers loads to B post and vehicle body, thus passenger's safety in the protection car.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of vehicle door anti-collision joist; Said car door anti-collision beam section is "
" type structure; Said door anti-collision joist is processed by the super-high strength steel steel pipe, and said door anti-collision joist adopts hot stamping method to be shaped.The external diameter of said super-high strength steel pipe is 50 ~ 60mm, and wall thickness is 1.0 ~ 2.0mm.The centre portion of said door anti-collision joist "
" type opening degree is 80 ℃ ~ 95 ℃.The two end portions of said door anti-collision joist "
" type opening degree is 95 ℃ ~ 120 ℃.The centre portion and the two end portions of said collision prevention girders seamlessly transit.The flanging width of said door anti-collision joist middle part is 10 ~ 12mm.The flanging width at said door anti-collision joist both ends is 15 ~ 20mm.Said door anti-collision joist stretching depth be 30 ~ 35mm.
The present invention adopts technique scheme; Compared with prior art; Said door anti-collision joist adopts the cross section of "
" font; Handle strength enhancing, crashworthiness optimization through heat forming technology; The connection support at said door anti-collision joist cancellation two ends is saved operation, and the lightweight effect is obvious; Said car door anti-collision beam end flanging width is convenient to weld with car door greater than the middle part.
Description of drawings
Fig. 1 is a door anti-collision joist structural representation of the present invention.
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 present invention is a kind of vehicle door anti-collision joist; Its cross section is "
" font structure; The door anti-collision joist front end is fixed near position, A column bottom; The rear end is fixed on the inner plate of car door near the position of B post lower end and car door pedal, in collision process, can preferably load be diverted to A post and B post.Compared with prior art; "
" font door anti-collision joist is beneficial to loading transfer in collision process, protect passenger's in the car safety better; The connection support at cancellation two ends is saved operation, and the lightweight effect is obvious; Car door anti-collision beam end flanging width is convenient to weld with car door greater than the middle part; Guarantee that simultaneously energy is delivered to body structure through the B post, buckling deformation can not take place in the B post, after accident takes place, still can open car door.
Door anti-collision joist adopts the super-high strength steel pipe through hot press-formed manufacturing process; Has good dimensional accuracy and very high intensity; And has good bending resistance; Adopt the cross section of "
" font simultaneously, whole collision prevention girders energy-absorbing effect in collision process is better.
The concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasions without improving, all within protection scope of the present invention.
