Embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, the technical scheme in the embodiment of the utility model is further described in more detail.
As stated in the Background Art, for covering overall structure in routine techniques, typically using composite material skin plus gold
Belong to support beam and support stringer of structure etc., but suffered much because metal material remains unchanged compared with composite quality, if will
Support beam and support stringer of metal material etc. are substituted for composite, because the change of material causes prototype structure intensity
It will change, and in order to both greatly mitigate the integrally-built weight of covering, and can improves preferable intensity, and proposes this reality
With new technical scheme.
It is the lightweight high-mechanic composite material skin overall structure signal of the embodiment of the utility model one as shown in Figure 1
Figure, lightweight high-mechanic composite material skin overall structure of the present utility model include covering 1, stringer 3 and crossbeam 2, covering 1, length
Purlin 3 and crossbeam 2 are that composite is made, and greatly alleviate the weight of structure.In covering overall structure, by multiple crossbeams
2 are be arranged in parallel and are connected with covering 1, and for providing main support force, and stringer 3 is arranged between two neighboring crossbeam 2,
And be connected with covering 1, for providing extra support power, the wherein global formation such as covering 1, stringer 3 and crossbeam 2.Wherein covering is
Thin matter covering.
In preferred embodiment of the present utility model, covering 1 is Nian Jie with crossbeam 2, covering 1 and stringer 3.In covering 1
It is Nian Jie between crossbeam 2, covering 1 and stringer 3 to form glue-line, because use is cementing rather than uses traditional screw, rivet etc.
Connector carries out mechanical connection manner, there is the weight for further mitigating structure.
In preferred embodiment of the present utility model, crossbeam as shown in Figure 3 and covering bonded structure schematic diagram, from figure
As can be seen that crossbeam 2, in general into " J " font, according to the difference of stress, the side of crossbeam 2 is T-shaped edge strip 21, T
The plane of type edge strip 21 is be bonded with covering 1 (i.e. parallel to the plane of covering 1), and for bearing compression, the opposite side of crossbeam 2 is
L-type edge strip 22, for bearing tension.
In preferred embodiment of the present utility model, stringer as shown in Figure 4 and covering bonded structure schematic diagram, stringer 3
It is integrated including the connecting portion 31 Nian Jie with covering 1, and section into the supporting part 32 of " ︹ " type, connecting portion 31 with supporting part 32
Configuration, it is generally into " Ω " type, and in " Ω " type stringer 3, supporting part 32 can form acute angle area with covering 1.Such a configuration
Stringer 3 has high bending stiffness, and high-flexural strength can be passed to the covering 1 cementing with it, and in order to further subtract
The integrally-built weight of light covering, the inside of " Ω " type stringer 3 is without sandwich (no filling) structure.
However, due to the acute angle area that supporting part 32 and covering 1 are formed, in order to improve the stability of the stringer 3 of no sandwich, sheet
Also include support cornual plate 4 in utility model, support the section of cornual plate 4 to be arranged at the inside of stringer 3 into " ㄥ " type, support cornual plate 4,
Support the one side of cornual plate 4 be bonded with supporting part 32, the another side of support cornual plate 4 is be bonded with covering 1, and bonding plane is respectively formed
Glued membrane, shown in reference picture 4, thus further enhance the intensity of stringer.
In preferred embodiment of the present utility model, support cornual plate 4 is two, is respectively arranged at the both sides of supporting part 32,
One side sets support cornual plate 4, and opposite side may be caused to be not provided with supporting the stringer 3 of cornual plate 4 with the fixing intensity deficiency of covering 1.
In the utility model, the quantity of stringer 3 being arranged between two neighboring crossbeam 2 is at least one.Certain stringer 3
Quantity nor The more the better, but in the zone of reasonableness that can provide the bending strength of covering 1, using the quantity of stringer 3
It is more few better, mitigate weight and complexity.
Further, when needing to set multiple stringers 3 between two crossbeams 2, needed between stringer 3 parallel and parallel
In crossbeam 2.
It should be noted that in embodiment of the present utility model, crossbeam 2 needs in advance curing molding alone, then passes through
Glued membrane 12 and the common cementation and formation of covering 1, at the same time, stringer 3, support cornual plate 4 pass through glued membrane 12 and the co-curing of covering 1 is molded.
In view of the shortcomings of the prior art and difficult point, the utility model proposes lightweight high-mechanic composite material skin integrally tie
Structure includes (thin) covering 1, the stringer 3 of the crossbeam 2 of J-type and Ω types and " ㄥ " type support cornual plate, and using work cementing altogether
Skill mode global formation, compared with the wing main force support structure configuration of routine, there is high-mechanic, in light weight, rigidity is big, integration
Technical characterstic.High-mechanic with thin matter covering 1, " J " type crossbeam, " Ω " type stringer 3 for technical characteristic combines profile pattern, real
Construction weight is further reduced while having showed raising bearing capacity；By using integral forming technique cementing altogether, not only greatly
The big usage amount for reducing fastener, reduce further construction weight, while decrease time that multiple material part enters autoclave
Number, saves manufacturing cost, shortens the manufacturing cycle, and the integration for improving product is horizontal.
Lightweight high-mechanic composite material skin overall structure of the present utility model is due to using such scheme and design so that
Lightweight high-mechanic composite material skin overall structure meets the requirements such as intensity, rigidity, weight.
It is described above, optimal embodiment only of the present utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with
The scope of the claims is defined.
