Fig. 2 a is the structural representation of the cushion frame according to the present invention one preferred implementation, and the cushion frame in the present embodiment comprises cushion frame body 7 and recliner.Fig. 2 b is the structural representation of recliner in Fig. 2 a, and Fig. 2 c is that the A-A of Fig. 2 b is to cutaway view.As shown in Fig. 2 b and Fig. 2 c, the recliner in the present embodiment comprises recliner body 1 and crumple aperture member, wherein: recliner body 1 has rotation hole 2 and rotating hole 3.Cushion frame body 7 is installed to recliner body 1 by the rotating bolt 6 be located in rotation hole 2 in the mode can rotated relative to recliner body 1.The height of rotation hole 2 is higher than rotating hole 3, and rotating hole 3 is as axle knock hole, and bolt had both played and installed fixing effect herein, played a part S. A. again.Under normal circumstances, the position of rotating hole 3 is determined, the hand of rotation of recliner body 1 just can be determined, thus the rotational trajectory of every bit on recliner body 1 all can be determined, therefore, the rotational trajectory being opened in the rotation hole 2 on recliner body 1 also can be determined, namely produces direction and is also correspondingly determined.
Described crumple aperture member is produce for starting point and along recliner body 1 through-hole structure that direction extends to form with rotation hole 2, this crumple aperture member along described in produce direction length the stressed displacement forward in the top of cushion frame body 7 can be made to be not less than 100mm and be not more than 400mm, the stressed displacement forward in bottom is not less than 50mm.
Because the present invention is starting point with rotation hole 2 and along the crumple aperture member that direction has extended to form through-hole structure that produces of recliner body 1, further, described crumple aperture member along described in produce direction length can make the top of cushion frame body 7 stressed backward before displacement be greater than 100mm and be less than 400mm and bottom stressed backward before displacement be not less than 50mm.
When carrying out GB13057 cushion frame crumple test, rotating bolt 6 can by the through-hole structure of crumple aperture member, be starting point with rotation hole 2 and direction of producing along recliner body 1 is slided, in this taxiing procedures, rotating bolt 6 and described through-hole structure relative motion and produce friction force, the moment of this friction force and the crumple of GB13057 cushion frame test in the moment of two test forces (F1 and F2 in Fig. 1) suitable, now rotating bolt 6 is producing in the process slided in direction along recliner body 1, also can rotate along through-hole structure simultaneously, thus the energy of test force effect can be sponged, reduce the shock strength being passed to seat, and the object of saving personal security in vehicle from damage can be reached.On the other hand, because the length producing direction described in described crumple aperture member edge can make the stressed backward front displacement in the top of cushion frame body 7 be greater than 100mm and be less than 400mm, and the stressed backward front displacement in bottom is not less than 50mm, therefore the cushion frame in present embodiment can meet the requirement of GB13057 cushion frame crumple test, thus, as long as the scheme that the cushion frame meeting the intensity class test requirements document that GB15083/GB11550 specifies provides according to present embodiment designs, then this cushion frame can save cae analysis when verifying, thus can development cost be saved, shorten time-to-market.And crumple aperture member provided by the present invention is formed on the basis of the mounting hole of original recliner body, and do not need to rely on H point and other opening, also without other particular/special requirement, manufacture craft is simple, with low cost.
The structural representation of what Fig. 3 a provided is recliner body 1 in prior art, shown in Fig. 3 b is the structural representation of recliner body 1 in the present invention.As shown in Figure 3 a and Figure 3 b shows, described crumple aperture member in the recliner that present embodiment provides comprise with rotation hole 2 for starting point along described in produce direction and extend to the edge of recliner body 1 and the open type through-hole structure that formed, in this, as the rotation hole of the recliner body 1 in the present embodiment.The processing technology of open type through-hole structure can adopt existing technique to realize.Time cushion frame is in the present embodiment subjected to external force collision, cushion frame body can pass through rotation hole 2, rotating bolt 6 and rotation hole 2 relative motion and produce friction force, the moment of this friction force and the crumple of GB13057 cushion frame test in the moment of impact suitable, now rotating bolt 6 is producing in the process slided in direction along recliner body 1, also can rotate along through-hole structure simultaneously, thus the energy of test force effect can be sponged, reduce the shock strength being passed to seat, and the object of saving personal security in vehicle from damage can be reached.
As shown in figures 4 a and 4b, the recliner that present embodiment provides also comprises brace panel 4, and brace panel 4 can be arranged on the lateral surface of recliner body 1 just, and is unlikely to the rotation having influence on recliner body 1.Described crumple aperture member also comprises rotation slot 5, and rotation slot 5 is arranged on position corresponding with rotation hole 2 on brace panel 4, and length direction parallels with described direction of producing, in rotary motion trace when therefore rotation slot 5 is positioned at cushion frame normal rotation.The length of rotation slot 5 is greater than the length of rotation hole 2.Certainly, on brace panel 4 except rotation slot 5 is set, also offer the rotating hole corresponding with the position of the rotating hole 3 on recliner body 1.During such use, the Main Function of brace panel 4 makes up the requirement that regulating control itself possibly cannot reach rotation hole Opening length, thus increases brace panel to ensure to meet the specification requirement of rotation hole.
Due in crumple process of the test; recliner can deform; rotary motion trace can depart from track during normal rotation; need to reserve enough amount of tolerance to make up the trail change being out of shape and causing; ensure that rotation is smooth and easy; the width of the rotation slot 5 therefore in the present embodiment need be a bit larger tham the diameter of the rotating bolt 6 penetrated wherein, is about 1.5 times of diameters of bolt.
In addition, consider that the length of the displacement of cushion frame in process of the test and rotation slot 5 is proportional, the length of rotation slot 5 is longer, then the displacement of cushion frame is larger.In view of GB13057 laws and regulations requirement: the top of cushion frame is subject to test force F1 effect, the stressed displacement forward in top of cushion frame is not less than 100mm and is not more than 400mm; The bottom of cushion frame is subject to test force F2 effect, and center of effort's point displacement forward of cushion frame is not less than 50mm.Therefore the length of rotation slot 5 also needs to limit.Drawn by test of many times result: the length of rotation slot 5 is about 2 to 3 times of the diameter of described rotating bolt 6.For certain vehicle seat, the described rotating bolt 6 at rotation slot 5 place is 10mm, therefore the length of rotation slot 5 is 20 ~ 30mm.
As shown in Figure 5, because rotating bolt 6 has both played, fixing effect was installed, played a part turning cylinder again, therefore, the rotating bolt 6 that rotation hole 2 in the cushion frame that present embodiment provides penetrates is shoulder bolt, with displacement required in warranty test, and meets:
T≤(F1*L1+F2*L2)*(sinα+cosα*μ2)*d/(2μ1*L3)；
In formula: T is the tightening torque of rotating bolt 6, F1 is the first test force that the top of described cushion frame is subject to, L1 is the arm of force of F1 to centre of gration O, F2 is the second test force that the bottom of described cushion frame is subject to, L2 is the arm of force of F2 to centre of gration O, F3 is the friction force that described rotating bolt 6 applies described cushion frame when rotating, and L3 is the arm of force of F3 to centre of gration O.Centre of gration O is the center of rotating hole 3.
The concrete derivation of above-mentioned conclusion is as follows:
F1*L1+F2*L2≥F3*L3
Wherein, F3=μ 1*F, in formula: F is the positive pressure of rotating bolt 6 pairs of brace panels 4, μ 1 is the friction coefficient that rotating bolt 6 contacts with brace panel 4.
To sum up obtain formula 1.: F≤(F1*L1+F2*L2)/(μ 1*L3)
As shown in 6 figure, the formula of the tightening torque of rotating bolt 6 is: T=(F4sin α+F4cos α * μ 2) * d/2
In formula, T is the tightening torque of rotating bolt 6, and α is the angle of thread of rotating bolt 6, and F4 is the pressure that the screw thread of rotating bolt 6 bears, and μ 2 is the screw thread of rotating bolt 6 and the friction coefficient of nut contact surface, and d is the pitch diameter of thread of rotating bolt 6.Pitch diameter of thread, bus is by the diameter of the protruding imaginary cylinder equal with groove width of tooth form.
Because the positive pressure of rotating bolt 6 pairs of brace panels 4 is identical with the pressure that the screw thread of rotating bolt 6 bears, therefore F4=F.
Therefore, formula 2.: F=2T/ [(sin α+cos α * μ 2) * d]
Composite type 1. and formula 2., the derivation of the tightening torque T of rotating bolt 6, the central diameter d of the screw thread of rotating bolt 6, the angle of thread α of rotating bolt 6 is as follows:
2T/[(sinα+cosα*μ2)*d]≤(F1*L1+F2*L2)/(μ1*L3)
Therefore:
T≤(F1*L1+F2*L2)*(sinα+cosα*μ2)*d/(2μ1*L3)
Therefore, when selecting bolt, the coefficientoffrictionμ 1 contacted with brace panel 4 by rotating bolt 6, the screw thread of rotating bolt 6 and the coefficientoffrictionμ 2 of nut contact surface, the central diameter d of the screw thread of rotating bolt 6 and the angle of thread α of rotating bolt 6 substitute in above formula, satisfactory this bolt of selecting as rotating bolt 6, then can arrange length and the width of the rotation slot 5 on brace panel 4.If undesirable, screw thread specification is made to be that Mn replaces to M (n+2), n is greater than and equals 6, until the tightening torque of rotating bolt 6 meets: T≤(F1*L1+F2*L2) * (sin α+cos α * μ 2) * d/ (2 μ 1*L3).Bolt tightening torque obtains with reference to existing screw thread specification table.
