Description
Technical field
It the utility model is related to technical field of aircraft structure design, more particularly to aircraft target ship docking structure.
Background technology
Existing technique for aircraft composite wallboard and metal wallboard are typically docked by the double lapping plates of uniform thickness.Lapping plate extend to etc.
Thickness design causes first row fastener load excessive；Metal wallboard and Composite Panels are identical in docking area thickness, due to
The nail extruding allowable value of Composite Panels is less than metal wallboard, causes metal wallboard thickness and weight big；Inside and outside lapping plate
The uniform strength design possibility that cracks both sides it is suitable, be unfavorable for structure inspection maintenance.
Utility model content
To overcome at least one defect existing for above-mentioned prior art, the utility model provides a kind of aircraft target ship docking
Structure, including Composite Panels, metal wallboard, docking costal margin bar and docking band plate, Composite Panels and metal wallboard are equal
It is fixed between docking costal margin bar and docking band plate, is left between Composite Panels and metal wallboard between wallboard by fastener
Gap, the thickness of docking costal margin bar is thinning from the wallboard gap location to both sides staged, and the thickness of band plate is docked in same section
Less than the thickness of docking costal margin bar.
Preferably, the thickness of metal wallboard is less than the thickness of Composite Panels, and docking costal margin bar and docking band plate are in institute
State wallboard gap location inflection.
Preferably, Composite Panels are fixed between docking costal margin bar and docking band plate by four row's fasteners, metal
Wallboard is fixed between docking costal margin bar and docking band plate by three row's fasteners.
Aircraft target ship docking structure provided by the utility model, has the advantages that：
1st, inner side lapping plate is extended to Varying-thickness, and the nail for reducing fastener carries, and solves fastener load distribution inequality
The problem of；
2nd, double lapping plates are in metal wallboard and Composite Panels joint inflection, and being easy to two side wall panels, uniform thickness does not dock,
Construction weight is alleviated, solves the problems, such as that construction weight is big；
3rd, lateral overlap plate thickness is less than inner side overlap joint plate thickness, crackle is appeared on lateral overlap plate, improving can
Inspection property, solves the problems, such as that maintainability is bad.

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.In the accompanying drawings, from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Described reality
It is the utility model part of the embodiment to apply example, rather than whole embodiments.Below with reference to the embodiment of accompanying drawing description
It is exemplary, it is intended to for explaining the utility model, and it is not intended that to limitation of the present utility model.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belong to the scope of the utility model protection.
In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, it is for only for ease of description the utility model and simplifies description, rather than indicates or imply and be signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The limitation of novel protected scope.
The utility model is described in further detail below by specific embodiment.
Specific embodiment：
The utility model provides a kind of aircraft target ship docking structure, for the connection at aircraft wing, such as Fig. 1 to Fig. 3
It is shown, including Composite Panels 1, metal wallboard 2, docking costal margin bar 3 and docking band plate 4, it is preferred that the He of docking costal margin bar 3
Docking band plate 4 is metal machine-made spares and material is aluminium alloy, and docking costal margin bar 3 and docking band plate 4 form double lapping plates,
Composite Panels 1 and metal wallboard 2 are fixed between docking costal margin bar 3 and docking band plate 4 by fastener 5, fastener 5
It is preferred that using bolt, in the present embodiment, Composite Panels 1 are fixed on docking costal margin bar 3 and jointing strip by four row's fasteners 5
Between plate 4, metal wallboard 2 is fixed between docking costal margin bar 3 and docking band plate 4 by three row's fasteners 5；
Leave wallboard gap between Composite Panels 1 and metal wallboard 2, the thickness of docking costal margin bar 3 is from the wallboard
Gap location is thinning to both sides staged, that is, dock costal margin bar 3 thickness extend it is thinning to one-level one-level, to reduce outside fastener
5 load, and the thickness that band plate 4 is docked in same section is less than the thickness of docking costal margin bar 3, makes the docking band plate positioned at outside
Semi-finals degree is weaker than the docking costal margin bar 3 positioned at inner side, crackle is appeared on the docking band plate 4 on the outside of wing, is easy to examine
Look into, i.e., the thickness sum of docking costal margin bar 3 and docking band plate 4 is constant in same section, simply thickness distribution between the two
Ratio is different, and this is not equal strength design, it is preferred that 3 basic thickness of docking costal margin bar is 4mm~8mm, is thinned at both ends as 3mm
~5mm；The thickness for docking band plate 4 is 3mm~4mm；
In the present embodiment, the thickness of metal wallboard 2 is less than the thickness of Composite Panels 1, docking costal margin bar 3 and jointing strip
In the wallboard gap location inflection, inflection causes rib edge strip 3 and docks the change of distance between band plate 4 plate 4, compound to realize
The not uniform thickness of material wallboard 1 and metal wallboard 2 docks, and meets that Composite Panels 1 and the thickness of metal wallboard 2 are different but can be with
Dock the demand of costal margin bar 3 and the docking fitting contact of band plate 4, it is preferred that docking costal margin bar 3 and docking band plate 4 are in metal wallboard 2
Place, respectively to the inflection 1mm~2mm of metal wallboard 2, the metal wallboard 2 of docking area is set to reduce compared with the thickness of Composite Panels 1.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in
Change or replace, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with described
Scope of the claims is defined.
