Abstract
The utility model discloses compound shell pieces, comprise aluminum alloy shell pieces and glass-felt plastic shell pieces, it is characterized in that: also comprise some nut integrated with the mold pressing of glass-felt plastic shell pieces; Also comprise the screw matched with nut; Described aluminum alloy shell pieces is provided with the some fixed orifices with nut screw connection, and described aluminum alloy shell pieces is connected with glass-felt plastic shell pieces by screw, nut; Also comprise adhesive-layer, described adhesive-layer is between aluminum alloy shell pieces and the contact surface of glass-felt plastic shell pieces; Described aluminum alloy shell pieces thickness h≤3mm.The utility model effectively can solve in conventional moulded mode the problem causing aluminum alloy shell pieces to be out of shape, and can ensure that compound shell pieces is solid and reliable, the housing structure be particularly useful for solar heat protection function designs, for giving the structure design of thin case, solve how at the technological problems of slim aluminum alloy shell pieces surface modes pressing glass steel.
Description
Technical field
The utility model belongs to aircraft casing technical field, is specifically related to a kind of compound shell pieces.
Background technology
Along with the fast development of weaponry, aircraft casing technology is developing to lightness gradually, the thickness of metal shell is also thinning gradually, for ensureing aircraft interior powder charge and the good compatible with environment of electric equipment, be a kind of comparatively ripe solar heat protection design at metal housing surface stem pressing glass reinforced plastics.
And traditional stem pressing glass reinforced plastics mode often needs the thickness of inner aluminum alloy shell pieces to be greater than 4mm, when aluminum alloy shell pieces thickness is not more than 3mm, traditional stem pressing glass reinforced plastics mode is no longer applicable.
Summary of the invention
The purpose of this utility model will provide a kind of compound shell pieces exactly, when aluminum alloy shell pieces thickness is not more than 3mm, effectively can solve in conventional moulded mode the problem causing aluminum alloy shell pieces to be out of shape, and can ensure that compound shell pieces is solid and reliable; The housing structure be particularly useful for solar heat protection function designs, and for giving the structure design of thin case, solves how at the technological problems of slim aluminum alloy shell pieces surface modes pressing glass steel.
For achieving the above object, the compound shell pieces designed by the utility model, comprises aluminum alloy shell pieces and glass-felt plastic shell pieces, it is characterized in that: also comprise some nut integrated with the mold pressing of glass-felt plastic shell pieces; Also comprise the screw matched with nut; Described aluminum alloy shell pieces is provided with the some fixed orifices with nut screw connection, and described aluminum alloy shell pieces is connected with glass-felt plastic shell pieces by screw, nut;
Also comprise adhesive-layer, described adhesive-layer is between aluminum alloy shell pieces and the contact surface of glass-felt plastic shell pieces; Described aluminum alloy shell pieces thickness h≤3mm.
Preferably, described screw is flathead screw.
Advantage of the present utility model is as follows:
(1) design flexibility is comparatively large, during structure design, thickness can be selected to be less than the main load-carrying construction of aluminum alloy shell pieces as aircraft of 4mm.
(2) sound construction, glass-felt plastic shell pieces and aluminum alloy can be connected two kinds of modes with screw and jointly be fixed by bonding, there will not be the situation of separation or unsticking.
(3) mounting means is simple, inherits the mode of conventional moulded glass-felt plastic, only increases simple screw and nut attaching parts.
(4) strong adaptability, goes for the structure design of aircraft exterior, also goes for other structure design with solar heat protection function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: aluminum alloy shell pieces 1, glass-felt plastic shell pieces 2, nut 3, screw 4, adhesive-layer 5.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, compound shell pieces of the present utility model, comprises aluminum alloy shell pieces 1 and glass-felt plastic shell pieces 2, also comprises integrated some nuts 3 with glass-felt plastic shell pieces 2 mold pressing; Also comprise the screw 4 matched with nut 3; Aluminum alloy shell pieces 1 is provided with the some fixed orifices coordinated with nut 3, and aluminum alloy shell pieces 1 is connected with glass-felt plastic shell pieces 2 by screw 4, nut 3; Also comprise adhesive-layer 5, adhesive-layer 5 is between aluminum alloy shell pieces 1 and the contact surface of glass-felt plastic shell pieces 2; Aluminum alloy shell pieces 1 thickness h≤3mm.Screw 4 is flathead screw.
Glass-felt plastic shell pieces 2 of the present utility model and nut 3 are first integrated by compression molding, then are fixed, by the further fixation of bonded adhesives between aluminum alloy shell pieces 1 and glass-felt plastic shell pieces 2 by screw 4 and aluminum alloy shell pieces 1.Screw 4 can be designed as the screw of flathead screw or other type according to space layout.
The above is preferred embodiment of the present utility model, but the utility model should not be confined to the content disclosed in this embodiment and accompanying drawing.The equivalence completed under not departing from spirit disclosed in the utility model so every or amendment, all fall into the scope of the utility model protection.
