For a kind of composite material tail-gate.
Composite material tail-gate described in the utility model, including the inner panel and outside plate of vehicle body are connected to each other to form, inside
Metal reinforcing plates and fiber band are provided between plate and outside plate, wherein the metal reinforcing plates include the first reinforcing plate, the second reinforcement
Plate and third reinforcing plate, wherein the first reinforcing plate and the second reinforcing plate form with the side region of vehicle body be rigidly connected respectively, third
The bottom area rigid of reinforcing plate and vehicle body connects, and the both ends of fiber band are clamped and fixed in the side region, the middle part of fiber band with
The bottom region connects.
First reinforcing plate and the second reinforcing plate are symmetrically disposed on the D columnar regions of composite material tail-gate both sides.
Third reinforcing plate is set to the lock region of composite material tail-gate bottom end.
Inner panel has the muscle that is stretched out towards outside plate, outside plate with slot structure, the end of fiber band be clipped in muscle and slot structure it
Between.
The slot structure is U-type groove structure.
Structure glue is filled in gap between fiber band and inner panel.
Structure glue is filled in gap between fiber band and outside plate.
It is opened up in third reinforcing plate there are two hole, fiber band is penetrated from a wherein hole and is pierced by from another hole to form series connection
Formula connects.
First reinforcing plate and the second reinforcing plate are formed by the side region of hinge and vehicle body respectively to be rigidly connected.
Third reinforcing plate is connect by latching with the bottom area rigid of vehicle body.
The utility model enhances the rigidity of composite material tail-gate by metal reinforcing plates, while bringing enhancing by fiber
The toughness of composite material tail-gate, to prevent composite material tail-gate from opening after an impact.Specifically, composite material tail-gate by
After high velocity impact, although inner panel is broken, pass through metal reinforcing plates and fiber band so that composite material tail-gate is still protected
An entirety is held, tail-gate will not be opened.

Fig. 1 is the structural schematic diagram of the composite material tail-gate of a preferred embodiment according to the present utility model；
Fig. 2 is the explosive view of Fig. 1；
Fig. 3 is the sectional view of the D columnar regions of Fig. 1；
Fig. 4 is the enlarged drawing in the lock region of Fig. 1.
Specific implementation mode
Below in conjunction with the accompanying drawings, the preferred embodiment of the utility model is provided, and is described in detail.
Fig. 1 is the structural schematic diagram of the composite material tail-gate of a preferred embodiment according to the present utility model, and Fig. 2 is figure
1 explosive view.The composite material tail-gate includes inner panel 1, outside plate 2, metal reinforcing plates 3 and fiber band 4.Between inner panel 1 and outside plate 2
Connection relation it is same as the prior art, details are not described herein, and the two is integrated into an entirety, can be directly described as vehicle body or
White body.
Unlike the prior art, metal reinforcing plates 3 are arranged in the utility model between inner panel 1 and outside plate 2.The metal
Reinforcing plate 3 includes the first reinforcing plate 31, the second reinforcing plate 32 and third reinforcing plate 33, wherein the first reinforcing plate 31 and second adds
Strong plate 32 is symmetrically disposed on the D columnar region A of composite material tail-gate both sides, is formed and is rigidly connected by hinge and vehicle body, third
Reinforcing plate 33 is set to the lock region B of composite material tail-gate bottom end, is formed and is rigidly connected with vehicle body by lock.
In the present embodiment, fiber band 4 is formed by glass fibre.It should be understood that the fiber band 4 can also by carbon fiber,
The materials such as nylon are formed.Preferably, the tensile strength of the fiber band 4 is not less than 4500N.
In the present embodiment, the both ends of fiber band 4 are individually fixed in the D columnar region A of composite material tail-gate both sides, it is intermediate with
The lock region B connections of composite material tail-gate bottom end, to ensure that composite material tail-gate keeps one after an impact by fiber band
A entirety, effectively prevent tail-gate to open.
Fig. 3 is the sectional view of the D columnar regions of Fig. 1, wherein there is inner panel 1 muscle 11 stretched out towards outside plate 2, outside plate 2 to have
The end 41 of slot structure 21, fiber band 4 is clipped between muscle 11 and slot structure 21, compound to which the end of fiber band 4 to be fixed on
The D columnar regions A of material tail-gate both sides.In the present embodiment, which is shown as U-type groove structure.It is further preferred that
Structure glue can be filled in gap between fiber band 4 and inner panel 1 and the gap between fiber band 4 and outside plate 2 22, from
And so that fiber band 4 is not only being sandwiched in the D columnar regions of composite material tail-gate both sides, and be adhesively secured herein.
Fig. 4 is the enlarged drawing in the lock region of Fig. 1, wherein opened up in third reinforcing plate 33 there are two hole, fiber band 4 from
Wherein a hole penetrates, and another hole is pierced by, and to form simple and reliable cascaded structure connection, is finally reached fiber band 4 and lock
The effect of region B connections.
In this way, in no fiber band, after composite material tail-gate is by high velocity impact, it is possible to two sections are fragmented into,
For epimere by being connected to vehicle body upper end, hypomere is connected to vehicle body lower end by lock, but there is no connection between two sections, this
When composite material tail-gate can be opened under the action of strut or vehicle travel inertia；Increase fiber band after, composite material tail-gate by
To high velocity impact, when fragmenting into two sections, continuous fiber belt passes through effect separated but still in each other's thoughts so that two sections remain attached to one
It rises, such composite material tail-gate would not be opened.That is, after composite material tail-gate is by high velocity impact, although inner panel
It is broken, but since metal reinforcing plates keep connection with vehicle body always, and metal reinforcing plates are connected to one by fiber band
It rises, to ensure that composite material tail-gate still maintains an entirety, tail-gate will not be opened.
Above-described, the only preferred embodiment of the utility model is not intended to limit the scope of the utility model, this
Above-described embodiment of utility model can also make a variety of changes.I.e. every claims according to the present utility model application and
Simple, equivalent changes and modifications, fall within the claims of the utility model patent made by description.This
The not detailed description of utility model is routine techniques content.
