Injury, collision energy needs reduction is gradually absorbed in transmittance process.And dashboard cross member is connected to body front wall, makees
Design for one of the critical path on central collision ability transmission path, endergonic structure also seems particularly critical.In addition, instrument board
Crossbeam is used to support steering column and steering wheel, is invaded in large quantities to driver when being collided in order to avoid steering wheel, and instrument board is horizontal
Beam must absorb local collision energy by energy absorber, to lower the energy for being transmitted to steering wheel, to protect driver.
Therefore, how to lower transmission of the front deck to cockpit collision energy during vehicle frontal collision, to reduce steering wheel position
The injury for occupant is moved, is that the application mainly solves the problems, such as, it is horizontal to design a kind of fascia of shrinkable energy-absorbing as a result,
Beam is particularly important.
Utility model content
The utility model is in view of the problems of the existing technology and insufficient, provides a kind of fascia of shrinkable energy-absorbing
Crossbeam absorbs and weakens the energy during central collision, to protect occupant, and promotes the security performance of automobile.
The utility model is to solve above-mentioned technical problem by following technical proposals：
The utility model provides a kind of fascia board girder, and feature is comprising a cross-beam body and a connection
Structure, the cross-beam body are connect by the connection structure with body front wall region, which includes that a crumple part and one protect
Gripping member, the crumple part are connected with the holder, which is connected with the body front wall region by bolt, the holder
It is connected with the cross-beam body, which includes the holder and a reinforcing rib of a wave-like, which is fixed on the branch
The inside of frame.
The crumple part is mainly deformed by crumple, to absorb and weaken collision energy；The holder is used to support steering tube
Column and steering wheel, in an impact can be the energy transmission that the crumple part passes over to steering column, and then is transmitted to steering wheel.
Undulating stent is crucial energy-absorption bracket, and shape can be controlled by the similar function such as sinusoidal or arcsin function, wavelength and
Amplitude is all adjustable, is determined according to the different crash requirements of vehicle.
Preferably, the length of the holder is more than the length of the crumple part.
Preferably, the crumple part and the holder are integrally formed.
Preferably, the fascia board girder further includes a connecting pin, which passes through in the connecting pin and vehicle body
Entreat channel connection.
Preferably, the reinforcing rib is cross reinforcing rib.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can arbitrarily combine to get the utility model respectively compared with
Good example.
The positive effect of the utility model is：
The shrinkable dashboard cross member of the utility model can absorb and weaken front deck by the wave-like holder of energy-absorbing
The collision energy of be transmitted to cockpit, and crash energy absorption effect can be changed by relevant parameter adjustment.Correspondingly,
The energy being eventually transferred on steering wheel can be reduced, the injury of occupant is reduced.

Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained without making creative work all belong to
In the range of the utility model protection.
Dashboard cross member is the critical component for connecting front deck part and cockpit part, can be inhaled by designing the structure of energy-absorbing
Receive and weaken the transmission of collision energy.Dashboard cross member front wall holder is directly to be connected with body front wall region by bolt,
This key transmits holder and integrates two kinds of structure types of crumple part and holder.
Specifically as shown in Figure 1, the present embodiment provides a kind of fascia board girders comprising a cross-beam body 1 and one connects
Binding structure, the cross-beam body 1 are connect by the connection structure with body front wall region 2, which includes 3 He of a crumple part
One holder 4, the crumple part 3 and the holder 4 are integrally formed, and the length of the holder 4 is more than the length of the crumple part 3, should
Crumple part 3 is connected with the holder 4, which is connected with the body front wall region 2 by bolt, the holder 4 with
The cross-beam body 1 is connected, which includes the holder 31 and a cross reinforcing rib 32 of a wave-like, which reinforces
Muscle 32 is fixed on the inside of the holder 31, and the material of the crumple part 3 can be by structures such as magnesium, magnesium alloy, aluminium, aluminium alloy or steel
At.
Moreover, the fascia board girder further includes a connecting pin 5, which passes through in the connecting pin 5 and vehicle body
Channel 6 is entreated to connect.
The outside support of the crumple part 3 designs waviness, by the deformation of wave structure and crumple after stress, and to
Holder 4 is drawn close, and realizes the absorption and weakening of collision energy.The interior design of crumple part 3 has cross reinforcing rib 32, on the one hand auxiliary
Adjustment crash energy absorption is helped, the rigidity requirement of dashboard cross member on the other hand can also be ensured by cross reinforcing rib 32, with
Make up the stiffness difference of wave structure and traditional structure.
The holder 4 is used to support steering column and steering wheel, while the collision energy that the crumple part 3 is passed over passes
It is delivered to steering column and steering wheel, it is ensured that the strength and stiffness of connection.
As shown in Figure 2,4, the size L1 and L2 of crumple part 3 are can to require to adjust accordingly according to different vehicles, with
Meet no crash requirements.And Wave-shaped structural can have the controls such as sinusoidal or arcsin function.
As shown in figure 3, after vehicle central collision, after cross-beam body 1 is hit by front deck, wave structure stress deformation and
Effect after crumple.
The crumple part 3 uses wavy shaped configuration, in collision process, by front deck impact force later, it can be achieved that crumple comes
Collision energy is absorbed, to reduce the ability being eventually transferred on steering wheel, reduces the injury of occupant.Corrugated structure be by
The similar function such as sinusoidal or arcsine controls, therefore the energy-absorbing effect of crumple section is adjusted by adjusting wavelength and amplitude, meets not
With the crash requirements of vehicle.In addition, also in wavy shaped configuration, the structure of reinforcing rib is increased, it also can be by adjusting this thickness
Crumple energy absorption performance is adjusted, certainly, this structure can also make up due to rigidity caused by wavy shaped configuration and Effect of Mode.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
Member can make these embodiments numerous variations or repair under the premise of without departing substantially from the principles of the present invention and essence
Change, but these change and modification each fall within the scope of protection of the utility model.
