Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-3, a kind of vehicle seat buffer unit, including seat body 1, the side of seat body 1 are provided with solid Fixed board 2, the top of fixed plate 2 are provided with mounting plate 3, and the structure of mounting plate 3 is L-type fixed plate, hinged on the transverse slat of mounting plate 3 There are movable plate 4, the plate face of movable plate 4 and the back side keeping parallelism of seat body 1, movable plate 4 is in the plate face of seat body 1 It is disposed with spring 5, the first catch bar and second connecting rod 14, end abutting joint of the spring 5 far from movable plate 4 from bottom to top On the riser of movable plate 4, the first catch bar is plugged in the first cylinder 7 far from the end of movable plate 4, the riser of mounting plate 3 On be disposed with support frame 6, fixed block 8 and fixing seat 12 from bottom to top, the top of fixed block 8 is provided with 10 He of the second cylinder The output end of sliding block 9, the second cylinder 10 is connected by the second catch bar with sliding block 9, is hinged with first connecting rod in fixing seat 12 13, the distance between transverse slat and riser of mounting plate 3 are obtuse angle, and obtuse angle range, at 120 ° -140 °, the first cylinder 7 is fixed to pacify On support frame 6, support frame 6 is fixedly mounted on the riser of mounting plate 3, the output end of the first cylinder 7 and the second cylinder 10 Input terminal between be fixedly connected by connecting tube 11, fixed block 8 is right angled triangle cylinder, and the inclined-plane of fixed block 8 deviates from Mounting plate 3, fixed block 8 offer sliding slot along inclined-plane, and sliding block 9 is sliding combined in the sliding slot, and the second cylinder 10 is located at sliding block 9 Lower section, second connecting rod 14 are hingedly fixed on movable plate 4, and end of the first connecting rod 13 far from fixing seat 12 and second connecting rod 14 are remote It hingedly installs end from movable plate 4.

In the present embodiment, in conjunction with Figure of description, it is provided with gas disengaging through-hole on the cylinder body of the first cylinder 7, is used for cylinder The positional relationship of body air inlet and outlet, first connecting rod 13 and second connecting rod 14 is as shown, the cross sectional shape of sliding block 9 is triangle Shape, people can press backward seat body 1, in layback so that movable plate 4 is pressed, so that cross of the movable plate 4 around mounting plate 3 Plate is rotated, during movable plate 4 is rotated: compressive deformation occurs for spring 5；First catch bar pushes the first cylinder Piston in 7 moves forward；The angle between first connecting rod 14 and the body of rod of second connecting rod 13 is gradually become smaller by obtuse angle simultaneously, In In the elastic range of spring 5, the gas in the first cylinder 7 is delivered in the second cylinder 10 by the first catch bar through connecting tube 11, Sliding slot of the sliding block 9 on fixed block 8 is pushed to be slided eventually by the second catch bar, later, spring 5 replys deformation, will live Movable plate 4 pushes back, and the first catch bar return, air inserts the first cylinder 7 again, and sliding block 9 drops to original position；

In the elastic range of spring 5, when automobile acutely shakes, and people acutely swings back, by movable plate 4 be pushed near Sliding block 9 is slid into fixed block 8 at this point, the gas in the first cylinder 7 is all delivered to the second cylinder 10 by the position of mounting plate 3 The top, at the same time, angle between first connecting rod 13 and the body of rod of second connecting rod 14 is minimum, while first connecting rod 13 The upper surface of the body of rod and sliding block 9 touches, and by the restriction that touches between first connecting rod 13 and sliding block 9, guarantees that movable plate 4 is difficult to again It is rotated to mounting plate 3, may finally achieve the effect that buffer seat, promote safety.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
