The present invention is directed to the situation of the prior art, overcomes drawbacks described above, protects transverse beam system before providing one kind.
The present invention use following technical scheme, it is described before protect transverse beam system include preceding guarantor's cross-beam body, preceding guarantor's energy-absorption box and
Preceding guarantor's crossbeam mounting plate, wherein：
Pass through macromolecular adhesive agent glue with preceding guarantor's cross-beam body respectively positioned at the preceding preceding guarantor's energy-absorption box for protecting the cross-beam body back side
It connects or is bolted；
Energy-absorption box is protected before each passes through macromolecular adhesive agent far from the preceding side for protecting cross-beam body and preceding guarantor's crossbeam mounting plate
It is glued.
According to the above technical scheme, the preceding energy-absorption box and the preceding quantity for protecting crossbeam mounting plate protected is 2.
According to the above technical scheme, the preceding cross-beam body of protecting is made of carbon fiber woven composite.
According to the above technical scheme, protected before described cross-beam body 1 first by carbon fiber through 3 D weaving device by evaporative pattern come
Braiding is returned, then is made with resin compounded through RTM technique.
According to the above technical scheme, the preceding energy-absorption box of protecting is arranged along the width direction of vehicle.
According to the above technical scheme, the preceding energy-absorption box of protecting is made of LET material injection.
According to the above technical scheme, the macromolecular adhesive agent is embodied as acrylate sqtructural adhesive.
According to the above technical scheme, the preceding cross-beam body of protecting is in curved square tube type, and cross-beam body is protected before described with hollow
Structure.
Transverse beam system is protected before disclosed by the invention, the beneficial effect is that, by applying carbon fibre composite and high score
The new materials such as sub- composite material, quality loss of weight 30%-40% compared with same type all steel bumper, it is light to help to realize vehicle
Quantization.Meanwhile collision energy-absorbing effect is improved, be conducive to protect pedestrian.

Appended drawing reference includes：Cross-beam body is protected before 1-；Energy-absorption box is protected before 1-；Crossbeam mounting plate is protected before 3-.
Specific embodiment
The invention discloses transverse beam system is protected before one kind, below with reference to preferred embodiment, to specific embodiment party of the invention
Formula is further described.
The preceding plan structure for protecting transverse beam system is shown to Fig. 3, Fig. 1 referring to Figure 1 of the drawings, Fig. 2 shows described
The preceding front view structure for protecting transverse beam system, Fig. 3 show the preceding backsight structure for protecting transverse beam system.
Preferably, the preceding transverse beam system of protecting includes preceding guarantor's cross-beam body 1, preceding guarantor's energy-absorption box 2 and preceding guarantor's crossbeam mounting plate
3, wherein：
Pass through macromolecular adhesive with preceding guarantor's cross-beam body 1 respectively positioned at the preceding preceding guarantor's energy-absorption box 2 for protecting 1 back side of cross-beam body
Agent is glued or is bolted；
Energy-absorption box 2 is protected before each far from the preceding side (the preceding back side for protecting energy-absorption box 2) for protecting cross-beam body 1 and preceding guarantor's crossbeam
Mounting plate 3 is glued by macromolecular adhesive agent.
Wherein, the preceding energy-absorption box 2 and the preceding quantity for protecting crossbeam mounting plate 3 protected is 2.
Further, the preceding cross-beam body 1 of protecting is made of carbon fiber woven composite, effectively realizes lightweight.
Specifically, the preceding cross-beam body 1 of protecting first is woven through 3 D weaving device by evaporative pattern by carbon fiber back and forth, then multiple with resin
Conjunction is made through RTM technique.
Further, the preceding energy-absorption box 2 of protecting is arranged along the width direction of vehicle.Specifically, preceding guarantor's energy-absorbing
Box 2 is made of LET material injection.Wherein, which has the spies such as good specific strength height, product stability, easy processing, recyclable
Point, compared with the energy-absorption box of production energy-absorption box made of the metal material can loss of weight 30%, and can absorb a part of load and touch
