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
The connection relationship diagram of 1 metal reinforcing plates and fiber band.The composite material tail-gate includes inner panel 1, outside plate 2, metal reinforcement
Plate 3 and fiber band 4.Connection relation between inner panel 1 and outside plate 2 is same as the prior art, and details are not described herein, and the two is integrated into
One 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 A- Fig. 3 B are the partial enlarged views of the end of the fiber band of Fig. 2.Fiber band 4 includes ontology 41 and connector 42, is connect
First 42 are fixed on the end of ontology 41.In the present embodiment, which is adapter of plastic, tight by way of insert injection moulding
Thickly it is connected to the both ends of ontology 41.
Fig. 3 C are the sectional views of the end of the fiber band of Fig. 2 and the junction of metal reinforcing plates, are welded in the first reinforcing plate 31
It is connected to nut 31a, the connector 42 of fiber band 4 is set on nut 31a, and bolt 31b is screwed in from the top of nut 31a, to
Connector 42 is blocked.In this way, one end of fiber band 4 is fixedly connected with the first reinforcing plate 31.Similarly, the other end of fiber band 4 with
Second reinforcing plate 32 is fixedly connected, to which the end of fiber band 4 to be fixed on to the D columnar regions A of composite material tail-gate both sides.
In the present embodiment, which has pressing groove 42a (referring to Fig. 3 A), for continuous fiber in adapter of plastic mould
Mold compresses fiber band body 41 when having embedded component injection molding.In addition, the connector 42, which has, adjusts muscle 42b (referring to Fig. 3 A), it is used for
The safety clearance of bolt end and the first reinforcing plate 31 (or second reinforcing plate 32) is controlled in 2-3mm.Moreover, the connector 42 also has
There is prepackage distribution 42c (referring to Fig. 3 B), unanimously with nut 31a (referring to Fig. 3 C), size is bigger 0.5- than nut outer profile for shape
1mm。
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.
