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, third reinforcing plate 33 and the 4th reinforcing plate 34, wherein first reinforces
Plate 31 and the second reinforcing plate 32 are symmetrically disposed on the D columnar region A of composite material tail-gate both sides, are formed just by hinge and vehicle body
Property connection, third reinforcing plate 33 is set to the lock region B of composite material tail-gate bottom end, is formed with vehicle body by lock and is rigidly connected
It connects, the 4th reinforcing plate 34 is set to the motor area C in the middle part of composite material tail-gate, and forming rigidity with vehicle body by fastener connects
It connects, rain shaving electrical machine is installed in the 4th reinforcing plate 34.
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 join end to end, D column of the which part not with composite material tail-gate both sides
Region A, composite material tail-gate bottom end lock region B connected with the motor area C of composite material tail-gate bottom end, to pass through fibre
Dimension band ensures that composite material tail-gate keeps an entirety after an impact, and tail-gate is effectively prevent to open, while preventing rain shaving electrical machine de-
It falls and flies out.
Fig. 3 is the enlarged drawing of the D columnar regions of Fig. 1, wherein is opened up in the first reinforcing plate 31 there are one hole, fiber band 4 passes through
The hole extend, to formed it is simple and reliable connected by formula, be finally reached the effect that fiber band 4 is connect with D columnar regions A.Together
Reason, fiber band 4 extend across the second reinforcing plate 32.
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.
Fig. 5 is the enlarged drawing of the motor area of Fig. 1, wherein opened up in the 4th reinforcing plate 34 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 motor
The effect of region C connections.
Fig. 6 is the sectional view along the line A-A of Fig. 5, wherein fiber band 4 has opposite first end 41 and the second end
End 42, the first end 41 and second end 42 overlap and carry out mechanical grip by metal intermediate plate 5 and fix, to make
It obtains fiber band 4 and is formed as whole coil structures.
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.
