Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, be the structural representation of the liftable energy-absorbing base for aviator's seat of the utility model embodiment, comprise lower connecting base 1 and upper connecting base 4, be provided with scissor-type lifting mechanism 2 between the two; The middle part that scissor-type lifting mechanism 2 comprises the first support arm 201, second support arm 202 and lifting regulating rod 3, first support arm 201 and the second support arm 202 is hinged, and the upper end of the first support arm 201 is provided with bending structure; Lower end and the described lower connecting base 1 of the first support arm 201 are hinged, upper end and upper connecting base 4 sliding block joint; The lower end of the second support arm 202 and lower connecting base 1 sliding block joint, upper end and upper connecting base 4 hinged; Lifting regulating rod 3, for regulating the first support arm 201 and the upper end of the second support arm 202 or the distance of lower end, is also provided with energy absorber 307 in the middle of lifting regulating rod 3.
When base is subject to vertical dynamic impulsion, if load reaches the startup load of energy absorber 307, energy absorber 307 starts, absorption portion load, if impact load is excessive, the screw thread of the bending part of the first support arm 301, screw mandrel 302 and rear fixed block 304 may be destroyed, and structural damage absorption portion energy, the integral energy-absorbing effect of seat is greatly improved.
As shown in Figure 2, be the schematic diagram of bending structure of the first support arm 201 of the utility model embodiment.When energy absorber 307 destructurized after, on the first support arm 201 arrange bending structure further can absorb impact dynamics.The point of contact, bending structure two ends of the first support arm 201 is A, C 2 point, and the midperpendicalar of A, C 2 lines is that BD, BD and the first support arm 201 intersect at D, E 2 point, and the ratio of the distance of two intersection point D, E and the maximum width CF of the first support arm 201 is 1/2-2/3.
Ratio for the first support arm 201, DE and CF distance that carry out weakening process determines static strength and the dynamic impulsion performance of support arm.Cut away different ratio situation lower branch arm Strength co-mputation to one group, show that ratio is larger, support arm is thicker, and static strength is good, but support arm absorbs energy not by distortion, thus anti-vertical dynamic impulsion poor-performing; Ratio is less, and support arm is thinning, and now anti-vertical dynamic impulsion performance is comparatively strong, but when applying static weight and reaching certain value, support arm is out of shape, and can not meet static strength requirement.So after testing in different ratio situation, draw best ratio range, when ratio is between 1/2-2/3, make device static support intensity and anti-vertical dynamic impulsion ability reach balance.Now by the structural failure of the bending structure of energy absorber 307 and the first support arm 201,26g horizontal dynamic can be born and to impact and the vertical dynamic of 19g impacts, greatly can improve aircraft and fall personnel's survival rate in situation of hitting.
As shown in Figure 3, Figure 4, be the structural representation of the lifting regulating rod 3 of the utility model embodiment, lifting regulating rod 3 comprises handle 301, screw mandrel 302, front fixed block 303, rear fixed block 304, front support axle 305, rear support axle 306 and energy absorber 307.Be provided with front support axle 305 between first support arm 201 upper end, front support axle 306 be provided with front fixed block 303, rear support axle 306 is provided with rear fixed block 304.Front fixed block 303 is through front support axle 305, and before keeping, fixed block 303 two side holes is concentric with front support axle 305 centre hole, and rear fixed block 304 is through rear support axle 306, and after keeping, fixed block 304 two side holes is concentric with rear support axle 306 centre hole.Handle 301 is by the centre hole of front fixed block 303 and front support axle 305, and handle 301 and front fixed block 303 are connected.Rotary screw 302, makes it by the centre hole of rear fixed block 304 and rear support axle 306.Front fixed block 303 is connected and fixed with one end of energy absorber 307, and rear fixed block 304 is connected and fixed with the other end of energy absorber 307.
During normal use, swinging handle 301, screw mandrel 302 is driven to rotate by energy absorber 307, screw thread and rear fixed block 304 screw thread fit on screw mandrel 302, two screw thread relative motions make screw mandrel 302 and fixed block 304 move in opposite directions or dorsad, drive front support axle 305 and rear support axle 306 to move in opposite directions or dorsad, force the first support arm 201 and the second support arm 202 angle reduce or increase, thus drive the distance variation of the first support arm 201 and the second support arm 202.In the present embodiment, drive the upper end distance variation of two support arms, in other embodiments, this lifting regulating rod 3 can also be arranged on the lower end of two support arms.The change of support arm distance reaches and drives base lifting object.The benefit of this elevating method is, the height of adjusting seat that can be stepless, and aviator's buttocks in the process regulated does not need to leave seat.
As shown in Figure 5, Figure 6, it is the structural representation of the scissor-type lifting mechanism 2 of the utility model embodiment, scissor-type lifting mechanism 2 also comprises middle studdle 203, front support rod 204, back support rod 205, front-slider 206 and rear slider 207, middle studdle 203 is by the centre hole of the hinge point of described first support arm 201 and the second support arm 202 and they are hinged, front support rod 204 is hinged with front-slider 206 by the second support arm 202, and back support rod 205 is hinged with rear slider 207 by the first support arm 201.
Two the first support arms 201 and two the second support arm 202 parallel placements respectively, two the first support arms 201 are placed in outside.Middle studdle 203 passes through the centre hole of two the first support arms 201 and two the second support arms 202, strut bar is set with spacing ring and lining, and installs packing ring additional as required.Front support rod 204 is connected with front-slider 206 by two the second support arms 202.Back support rod 205 is connected with rear slider 207 by two the first support arms 201.Front-slider 206, rear slider 207 slip into the slideway of lower connecting base 1.Stop pin is equipped with in rear slider 207 inside, can be locked on lower connecting base 1.During locking, the parallel motion of front-slider on lower connecting base 1 can be realized by change the second support arm 202 of scissor-type lifting mechanism 2 and the angle of the first support arm 201.
As shown in Figure 7, be the structural representation of upper connecting base 4 of the utility model embodiment.Upper connecting base 4 comprises Connection Block main body, and the prelocalization block 401 be all fixedly connected with this Connection Block main body and rear locating piece 402.Prelocalization block 401, rear locating piece 402 are fixedly connected with Connection Block main body respectively.Front support axle 305 is from the middle to both ends successively through the first support arm 201 and prelocalization block 401.Rear support axle 306 is from the middle to both ends successively through the second support arm 202 and rear locating piece 402.In installation process, strut bar is set with spacing ring and lining, and installs packing ring as required additional all parts is located.
