Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
As shown in figure 1, it is that the structure of the liftable energy-absorbing base for pilot's seat of the embodiment of the present invention is shown
It is intended to, including lower connecting base 1 and upper connecting base 4, scissor-type lifting mechanism 2 is provided between the two；Scissor-type lifting mechanism 2 wraps
First support arm 201, second support arm 202 and lifting regulating rod 3 are included, the middle part of first support arm 201 and second support arm 202 is hinged, the
The upper end of one support arm 201 is provided with bending structure；The lower end of first support arm 201 is be hinged with the lower connecting base 1, upper end and upper company
Joint chair 4 is slidably connected；The lower end of second support arm 202 is slidably connected with lower connecting base 1, and upper end is be hinged with upper connecting base 4；Rising-falling tone
Pole 3 is used for upper end or the distance of lower end for adjusting first support arm 201 and second support arm 202, is also set among lifting regulating rod 3
It is equipped with energy absorber 307.
When base is by vertical dynamic impulsion, if load reaches the startup load of energy absorber 307, energy absorber 307
Start, absorb fractional load, if shock loading is excessive, bending part, screw mandrel 302 and the rear fixed block 304 of first support arm 301
Screw thread be likely to be broken, structural damage absorbs portion of energy, and the integral energy-absorbing effect of seat is greatly improved.
As shown in Fig. 2 it is the schematic diagram of the bending structure of the first support arm 201 of the embodiment of the present invention.When energy absorber 307
After destructurized, the bending structure set in first support arm 201 can further be absorbed to impact dynamics.First
The bending structure both ends point of contact of support arm 201 is 2 points of A, C, and the perpendicular bisector of 2 lines of A, C is BD, BD and the phase of first support arm 201
2 points of D, E is met at, two intersection point D, E distance and the Breadth Maximum CF of first support arm 201 ratio are 1/2-2/3.
First support arm 201 for carrying out weakening process, the ratio of DE and CF distances determine the static strength of support arm and moved
State impact property.Different ratio situation lower branch arm Strength co-mputations are cut away to one group, show that ratio is bigger, support arm is thicker, static strength
It is good, but support arm absorbs energy not by deformation, thus resist vertical dynamic impulsion poor-performing；Ratio is smaller, and support arm is thinned, this
When resist vertical dynamic impulsion performance stronger, but apply dead load reach certain value when, support arm deformation, it is impossible to meet static strength will
Ask.So after being tested in the case of to different ratios, optimal ratio range is drawn, when ratio is between 1/2-2/3,
So that device static support intensity and anti-vertical dynamic impulsion ability reach balance.Now pass through energy absorber 307 and first support arm
The structure of 201 bending structure is destroyed, and the vertical dynamic that can bear the impact of 26g horizontal dynamics and 19g impacts, and can carry significantly
Personnel's survival rate in the case of high aircraft pendant is hit.
