Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
This front anti-collision beam structure of the present invention, as shown in Figure 1,2,3, 4, including front beam 1 and energy-absorbing structure connected to it
Part 2.Energy absorbing members 2 are an integral molding structure, and are become larger in section from front to back along the direction vehicle body x, i.e., by connecting with front beam
End to rear stringer connection end section becomes larger (left and right directions as shown in Figure 2), while improving shape extrusion utilization rate,
The crumple energy-absorbing step by step of endergonic structure part collision process can be achieved；The both ends of energy absorbing members 2 are removably attachable to preceding cross respectively
On beam 1 and front stringpiece of vehicle body.For only front beam is damaged situation in low speed impact, no replacement is required, and front anti-collision beam is total
At, it can be to its independent dismounting and change, reduction after-sales service cost.As shown in Figure 3,4, the energy absorbing members are by before integrally formed
Installation end, intermediate energy-absorbing plate and rear installation end composition, save the additional processing and forming of traditional front anti-collision beam mounting plate, save simultaneously
Energy-absorption box and mounting plate welding sequence.
In the present invention, as shown in Figure 2, the whole trapezoidal structure of energy absorbing members 2 improves the same of shape extrusion utilization rate
When, it can be achieved that endergonic structure part collision process crumple energy-absorbing step by step.This kind of structure on endergonic structure part without additionally opening up
Crumple induction muscle can reduce collision process peak-peak load, can effectively prevent front longitudinal beam that crumple, drop occurs compared with front anti-collision beam
Low process costs.
In the present invention, as shown in Fig. 3,4, energy absorbing members 2 include the preceding installation end 21 and and vehicle body connecting with front beam 1
The rear installation end 22 of front longitudinal beam connection, is equipped with spaced apart multiple guiding energy-absorbings between preceding installation end 21 and rear installation end 22
Plate 23.Energy-absorbing plate 23 and the direction vehicle body x are oriented in 0 ° of -90 ° of arrangement, can be to be arranged in parallel or interlaced arrangement, it can be according to reality
Demand is configured.
It is as shown in Figure 3,4 two kinds of arrangement forms of crossbeam mounting hole in the present invention, preceding installation end 21 is equipped with corresponding connect
The crossbeam mounting hole 24 being connected on front beam.24 position of energy absorbing members front end cross beam mounting hole can be opened according to actual needs
If can both be located at guiding 23 liang of side positions of energy-absorbing plate, it is also disposed at guiding 23 inner side of energy-absorbing plate.It is set on installation end 22 afterwards
There is the stringer mounting hole 25 being correspondingly connected on front stringpiece of vehicle body.Preferably, to guarantee stable installation connection, energy absorbing members 2 are along x
Direction middle line is arranged symmetrically there are two crossbeam mounting hole 24 and two stringer mounting holes 25.
In the present invention, as shown in Figure 2, front beam 1 is rectangular beam, is pacified after being equipped with crossbeam on 1 rear end side wall of front beam
Hole 12 is filled, the mounting hole 11 before front beam front end side wall position corresponding with mounting hole 12 after crossbeam is equipped with crossbeam.Pacify before crossbeam
It fills 11 size of hole and is greater than mounting hole 12 after crossbeam.Crossbeam mounting hole after crossbeam on front beam on mounting hole 12 and energy absorbing members
24 be bolt hole, and the connection of front beam and energy absorbing members can be realized by bolt, for only front beam is sent out in low speed impact
Raw damaged condition, no replacement is required front anticollision beam assembly can reduce after-sales service cost to its independent dismounting and change.Preferably, it is
Guarantee convenient installation, mounting hole 11 can be set as waist-shaped hole before crossbeam.
In the present invention, stringer mounting hole 25 is offered on the rear installation end 22 of energy absorbing members 2, stringer mounting hole 25 is bolt
Hole, it can be achieved that energy absorbing members and front stringpiece of vehicle body connection.Wherein, 25 position of energy absorbing members rear end stringer mounting hole can be according to reality
Border demand is opened up, and can be both located at rear end face and has been oriented to 23 liang of side positions of energy-absorbing plate, can also be located at rear end face and is oriented to energy-absorbing
23 inner side of plate.Meanwhile the determination of the specific height of stringer mounting hole 25 need to be determined in conjunction with front rail structure, its usual height compared with
The crossbeam mounting hole 24 of the front end face of energy absorbing members is high.
In the present invention, as shown in Fig. 5,6, energy absorbing members 2 can be sheared on long section extrudate 3 and obtain trapezium structure,
Long section extrudate 3 is along vehicle body z to integrated extrusion forming.Such energy absorbing members can save the mounting plate for connecting with front longitudinal beam
Component, while the welding sequence of mounting plate is reduced, reduce cost.
In the present invention, the front beam 1 and energy absorbing members 2 of front anti-collision beam all select aluminum alloy materials, convenient for being integrally squeezed into
Type satisfies the use demand.
Front anti-collision beam structure of the present invention, the energy absorbing members of front anti-collision beam are along vehicle body Z-direction one extrusion forming, with tradition along vehicle
Body X is compared to endergonic structure part is squeezed, and can save additional mounting plate component, while reducing the welding sequence of mounting plate, is reduced
Cost；Energy absorbing members are gradually increased along vehicle body X to depth of section from front to back, improve shape extrusion utilization rate simultaneously, it can be achieved that
The crumple energy-absorbing step by step of endergonic structure part collision process, this kind of structure on endergonic structure part without additionally opening up crumple induction
Muscle can reduce collision process peak-peak load, and front longitudinal beam is effectively prevent first to occur crumple compared with front anti-collision beam, reduce technique at
This；Front anti-collision beam front beam of the present invention is connect with energy absorbing members 2 using detachable connection method, convenient for the disassembly of front beam, greatly
It is big to reduce after-sales service cost.
The present invention also protects a kind of automobile, including vehicle body, and vehicle body is equipped with this above-mentioned front anti-collision beam structure, can be obtained compared with
Good energy-absorbing effect, processing and fabricating easy to produce are easily installed connection and replacement, can reduce subsequent maintenance cost.
Front anti-collision beam structure of the present invention and automobile, structure is simple, and the additional molding for saving traditional front anti-collision beam mounting plate adds
Work, while mounting plate and energy-absorption box welding sequence are saved, it is easily installed disassembly, and the energy absorbing members of trapezium structure can be realized step by step
Crumple, damping energy-absorbing effect is good, has stronger practicability and preferable application prospect.
The present invention is exemplarily described above in conjunction with attached drawing, but the present invention is not limited to aforesaid way, only
