Lid is thrown, the lid side of throwing has the shape to match with the dentation fixed edge, and on the periphery for throwing lid
Equipped with it is multiple for it is described close that the slot that links closely matches close link closely so that throwings cover it is relatively fixed with the frame, wherein
It is described close to link closely be convex in air bag cabin.
In the present invention, dentation is equilateral triangle structure in the dentation fixed edge.
In the present invention, it is described close to link closely in slot to have be depressed in close the slot inside diameter surface that links closely first and limit slot,
And close upper be equipped with of linking closely described and protrude from first limited section for closing the external diameter surface that links closely, described first limits slot and the
The one limited section cooperation.
In above-mentioned utility model, described first limits the depth of slot no more than 1mm and the height of first limited section
Degree is not more than 1mm.
In the present invention, it is described close to link closely to have in slot protrude from the second limited section for closing the slot inside diameter surface that links closely,
And link closely in described close above equipped with the second restriction slot for closing the external diameter surface that links closely is depressed in, described second limits slot and institute
State the cooperation of the second limited section.
In above-mentioned utility model, described second limits the depth of slot no more than 1mm and the height of second limited section
Degree is not more than 1mm.
It is highly dense that the air bag cabin canopy jettison mechanism for reducing detection area of the utility model forms air bag cabin throwing lid structure
Envelope form not only ensure that the functional requirement of air bag cabin canopy jettison mechanism, but also the detectivity index of aircraft can be made to be preferably minimized,
Achieve the purpose that not increase strong scattering direction.

Specific embodiment
To keep the purposes, technical schemes and advantages of the utility model implementation clearer, below in conjunction with the utility model
Attached drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the utility model.
As shown in Fig. 2, the air bag cabin canopy jettison mechanism for reducing detection area of the utility model, by throwing lid for installing
2 frame 1 and the throwing lid 2 being installed on frame 1 are constituted.
Setting at the periphery interval of frame 1 is multiple to close the slot 11 that links closely for install throwing lid 1, furthermore in order to reduce air bag
The detectivity of cabin canopy jettison mechanism, frame 1 are set as dentation fixed edge 12 in the side windward of air-flow, and arrow W is air-flow in figure
Flow direction.Experiment proves that being remarkably improved the detectivity for reducing aircraft in windward side setting dentation fixed edge.
In the utility model embodiment, the dentation of dentation fixed edge 12 is equilateral triangle structure.
It should be noted that the reduction of above-mentioned aircraft detectivity is not because of windward side by the structural plane of neat shape
Product reduce and reduce, but because reasonable position be provided with reasonable shape be able to the detectivity of aircraft
It reduces.
As shown in figure 3, the side for throwing lid 2 has a side to match with the dentation fixed edge 12 of frame 1, and covered throwing
2 remaining periphery is equipped with multiple for linking closely 21 so that throwing lid 2 and frame 1 is relatively solid with closing of closing that the slot 11 that links closely matches
It is fixed, it 21 is convex in air bag cabin wherein closing to link closely.
The slot 11 and closing of linking closely that closes along frame 1 and the circle setting of periphery one for throwing lid 2 links closely 21, completes to throw under mating reaction
The fixation of lid 2, when the air bag in air bag cabin is expanded due to inflation, air bag, which can overcome, to be closed the slot 11 and closing of linking closely and links closely between 21
Restraining force to throw the disengaging of lid 2 in frame 1.
An embodiment of the present invention as shown in fig. 4 a closes to have to be depressed in the slot 11 that links closely and closes the slot inside diameter surface that links closely
First limit slot 121, and protrude from the first limited section 211 for closing the external diameter surface that links closely closing to link closely to be equipped on 21, first
It limits slot 121 and the first limited section 211 cooperates, achievable throwing lid 2 is relatively fixed with frame 1.
In the above-described embodiments, first the depth of slot 121 is limited no more than 1mm and the height of the first limited section 211
No more than 1mm.Deeper restriction slot and limited section will cause air bag and be not easy air bag cabin throwing caping in the expanded state, and compared with
Shallow restriction slot and limited section then easily cause air bag cabin to throw falling off for lid, not can guarantee the safety of air bag.
Another embodiment of the utility model as shown in Figure 4 b closes to have to protrude from the slot 11 that links closely and closes the slot inside meter that links closely
Second limited section 122 in face, and be depressed in close the external diameter surface that links closely second closing to link closely to be equipped on 21 and limit slot 212, the
Two limited sections 122 and second limit the cooperation of slot 212.
Second depth for limiting slot 212 is not more than 1mm no more than the height of 1mm and the second limited section 122.Similarly
, deeper restriction slot and limited section will cause air bag and be not easy air bag cabin throwing caping in the expanded state, and shallower limit
Determining slot and limited section then easily causes air bag cabin to throw falling off for lid, not can guarantee the safety of air bag.
It is highly dense that the air bag cabin canopy jettison mechanism for reducing detection area of the utility model forms air bag cabin throwing lid structure
Envelope form, not only ensure that the functional requirement of air bag cabin throwing lid structure, but also the detectivity index of aircraft can be made to be preferably minimized,
Achieve the purpose that not increase strong scattering direction.
The above, the only optimal specific embodiment of the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with
Subject to the scope of protection of the claims.
