Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
It should be noted that in the description of the invention, term " transverse direction ", " longitudinal direction ", " on ", D score, "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " are based on accompanying drawing institute
The orientation or position relationship for showing, are for only for ease of the description present invention and simplify description, are not the dress for indicating or implying meaning
Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limit of the invention
System.Additionally, term " first ", " second " etc. are only used for describing purpose, and it is not intended that indicating or implying relative importance.
Referring to figs. 1 to Fig. 4, in this preferred embodiment, a kind of energy absorption device for aero seat, including it is fixed on backrest
Shear pin 20 on 10 and the lock connecting plate 30 being placed on shear pin 20, wherein,
Lock one end of connecting plate 30（Fixing end 35）It is fixedly connected with seat-assembly, the other end for locking connecting plate 30 cuts with scissors with backrest 10
Connect（Lock connecting plate 30 is hinged by rotary shaft 40 with backrest 10）, mounting hole 32 and fluting 31 are offered on lock connecting plate 30,
Lock connecting plate 30 between mounting hole 32 and fluting 31 forms shearing ring 33, and shear pin 20 is contained in mounting hole 32, works as external force
Act on when on backrest 10, drive backrest 10 to be rotated relative to lock connecting plate 30, and then driving shear pin 20 to rotate destroys it
Shearing ring 33.
Reference picture 4, in the present embodiment, the width h of shearing ring 33 is 3-5mm.Shear direction is to lock consolidating for connecting plate 30
Fixed end 35 is round dot, with the counterclockwise arc direction that the distance between fixing end 35 and the center of shear pin 20 are drawn for radius.When cutting
When cutting 20 stress of pin, shear pin 20, so as to destroy shearing ring 33, realizes first time energy-absorbing relative to the counterclockwise movement of fixing end 35,
To play certain protective effect to occupant.
Reference picture 4, further, this energy absorption device for being used for aero seat also includes being fixed on fluting 31 away from shearing ring
The web 34 of 33 sides, after the destruction shearing ring 33 of shear pin 20, shear pin 20 can be rotated further destruction web 34 to carry out the
Secondary energy-absorbing.Further, lock connecting plate 30 is formed in one with web 34, the thickness of the thickness less than lock connecting plate 30 of web 34
Degree, so as to reduce the cost of manufacture of this energy absorption device.In processing, monoblock lock connecting plate 30 is first processed, then in the area of web 34
Domain will lock the thickness of connecting plate 30 and reduce, you can forming web 34.
Further, upper and lower ends of the mounting hole 32 near the side of shear pin 20 are equipped with answering along shear direction opening
Power ring 36.By setting NOL ring 36, concentrate the shearing force of shear pin 20 and act on shearing ring 33.
The operation principle of this energy absorption device is as follows：When in the top applying power F of backrest 10（Forward, touched equivalent to occupant's head
The power produced when hitting）When, power is delivered on shear pin 20 by backrest 10, because lock connecting plate 30 is fixed, lock connecting plate
Shearing ring 33 on 30 is the part of the directly contact of shear pin 20, is again most weak position, so the power for applying is delivered to lock and connects
When on fishplate bar 30, the shearing ring 33 locked on connecting plate 30 can be destroyed, power can be released, and reach the effect of energy-absorbing.If power foot
It is enough big, so devising second structure of buffering energy-absorbing on lock connecting plate 30 again, by web 34, make power obtain buffering simultaneously
By energy absorption.
In this energy absorption device, lock connecting plate 30 is particularly important, plays energy-absorbing and spacing effect.Control energy absorption journey
Degree, mainly by changing the thickness of shearing ring 33 on lock connecting plate 30（That is h in Fig. 4）And NOL ring 36（It is main to produce stress
Concentrate）Position size controls first time energy-absorbing degree, by change the thickness and length of lock connecting plate 30 epiplastron 34 come
Control second energy-absorbing degree.
The energy absorption device for aero seat that the present embodiment is proposed, by setting energy absorption device, in aircraft emergency landing
When, occupant's head injury is minimized when heel row occupant is arranged before the collision in the rigid structure of backrest 10, occupant is risen
Certain protective effect.This energy absorption device has the advantages that simple structure, easy to use and reliable and low cost.This energy absorption device
It is used in civil aviaton's seat, seat has passed through the experiment of standard requirement and achieved the certificate of seaworthiness of correlation, it is ensured that seat
Security so that occupant escapes injury.
The preferred embodiments of the present invention are these are only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair
The equivalent structure transformation that bright specification and accompanying drawing content are made, or other related technical fields are directly or indirectly used in,
Similarly it is included within the scope of the present invention.
