The every other embodiment obtained, shall fall within the protection scope of the present invention.
It is the embodiment one of the utility model anti-collision beam structure of car as shown in Fig. 1-Fig. 7.
Referring to Fig. 1-Fig. 2, the anti-collision beam structure of car in the present embodiment can be applied on the arbitrary car door of automobile, below
Illustrate the installation site and concrete structure of door anti-collision joist with car door assembly structure shown in Fig. 1-2.
Car door assembly A in the present embodiment includes the inner plate of car door A1 and door skin A2 that installation can be adapted to it, vehicle
The door adaptation of collision prevention girders 1 is fastened on inner plate of car door A1.When implementation, the size of door anti-collision joist 1 can be according to the ruler of practical car door
Very little to be adjusted, to be assembled on the corresponding position of inner plate of car door A1, the door anti-collision joist 1 in the present embodiment fills
On the diagonal position for fitting over vehicle front door inner panel A1.
Door anti-collision joist 1 in the present embodiment using high-strength steel cold punching technology or uses high-strength steel thermoforming process system
At, wherein：High-strength steel tensile strength is between 980-2000Mpa, and material thickness is between 1.2-3.0mm, so：It can ensure
Door anti-collision joist 1 has certain compression strength.
Further, door anti-collision joist 1 includes：Anticollision beam body 11 and extend from the ends of anticollision beam body 11
And set being overlapped on the bond end 12 on car door corresponding position；Wherein：Anticollision beam body 11 is from its middle part 11a to opposite
Section thickness that both ends 11b is extended difference is tapered to be narrowed, and anticollision beam body 11 is from its middle part 11a to opposite both ends
The cross-sectional width that 11b is extended is incremented by gradually respectively.
The above structure of door anti-collision joist 1 makes anticollision beam body 11 keep the structure of variable cross-section to set in the direction of its extension
Meter, that is to say, that the thickness of the middle part 11a of anticollision beam body 11 is most thick and width is most narrow, the both ends 11b of anticollision beam body 11
Appropriate thinned and width increases, so so that collision prevention girders main body 11 has certain stability and shock proof ability.
In other embodiment, it is further opened in anticollision beam body 11 to be assembled the positioning on inner plate of car door A1
Hole 110.
Further, bond end 12 extends from the ends 11b of anticollision beam body 11 and is set, and bond end 12 can be
It is overlapped in the processing procedure of fit a door collision prevention girders 1 on the corresponding position of inner plate of car door A1.In the present embodiment, the end of bond end 12
The tapered receipts of section thickness extended from the end 11b being connected with anticollision beam body 11 to end 12a for 12a, bond end 12
It is narrow；The cross-sectional width that bond end 12 is extended from the end 11b being connected with anticollision beam body 11 to end 12a is incremented by gradually.
The above structure of bond end 12 makes the whole structure that variable cross-section is kept in the direction of its extension of door anti-collision joist 1
Design, that is to say, that the thickness of the middle part 11a of anticollision beam body 11 is most thick and width is most narrow, and the both ends 12a of bond end 12 subtracts
Keep maximum to relatively thin and width, in this way, the entirety in door anti-collision joist 1 keeps the same of certain stability and shock proof ability
When, but also the overlapping regions of bond end 12 is maximum, effective dispersion and transmission impact stresses.
Preferably, anticollision beam body 11 and bond end 12 are integrally formed, and are so conducive to simplify production technology, are promoted preventing car door
Hit the stability of beam 1 and shock proof ability.
Preferably, the section of the middle part 11a of anticollision beam body 11 is in shape of chinese word Ji, as shown in Figure 5.The section of bond end 12 is in
M fonts, as shown in fig. 6-7.The effect of such setting is：Collision energy is effectively absorbed, while expanding taking for both ends overlapping regions
Junction is accumulated, effective dispersion and transmission impact stresses.
Further, further include：The reinforcer 2 being fastened in anticollision beam body 11,2 enclosing of reinforcer is in anticollision beam body
Hollow closed section is formed on 11, as shown in figure 5, the section structure of the door anti-collision joist 1 to be equipped with reinforcer 2.
Preferably, the end face of reinforcer 2 be in shape of chinese word Ji, can enclosing anticollision beam body 11 form hollow cavity configuration.
By the way that the structure is arranged, the anti-collision energy of door anti-collision joist is further promoted.
Preferably, anticollision beam body 11 is extended from the middle part 11 of the two to opposite both ends together with reinforcer 2
Section thickness difference is tapered to be narrowed, and anticollision beam body 11 is prolonged together with reinforcer 2 from the middle part of the two to opposite both ends
The cross-sectional width stretched is incremented by gradually respectively, in this way, promoting the stability of door anti-collision joist and shock proof ability, enhances preventing car door
Hit the anti-collision energy of beam.
In the other embodiment of door anti-collision joist in the present embodiment, the reinforcer 2 of above structure can also be applied
In conventional anticollision beam body, as long as meeting anticollision beam body together with reinforcer 2 from the middle part of the two to opposite both ends
The section thickness difference that is extended is tapered to be narrowed, and anticollision beam body 11 is together with reinforcer 2 from the middle part of the two to opposite two
The cross-sectional width difference that end is extended is incremented by gradually, which still has the stability for promoting door anti-collision joist and resist
The ability of impact enhances the technique effect of the anti-collision energy of door anti-collision joist.
The anti-collision beam structure of car and automobile of the utility model, have the advantages that：
The first, anti-collision beam structure of car includes that anticollision beam body and the ends from anticollision beam body extend and set
To the bond end being overlapped on car door corresponding position；Wherein：Anticollision beam body is prolonged from its middle part to opposite both ends
