Specific embodiment
As shown, four bar folding safety airbag fold mechanisms, including foldable structure and four bar power rotation structures,
Wherein, foldable structure includes clamping plate 1, Boards wall part 2, gear I 3, bearing I 4, gear II 5, rack gear 6, gear III
7, bearing II 8 and support frame 9.The inner wall of support frame as described above 9 is fixedly connected with the intermediate bar 10 being laterally arranged；The intermediate bar 10
On be set with sliding block 16.The specific jackknife action of foldable structure progress air bag.
Four bar power rotation structures include: crank 12, connecting rod I 13, exhibition bar 14, connecting rod II 15 and support II 17；Four bars are dynamic
Power revolving structure, which not only serves, provides power, but also due to the special revolution property of the structure, foldable structure can be made long at one section
Iterative motion is done along rack gear 6 in degree.
In four bar power rotation structures, crank 12 is used as driving lever, and one end of crank 12 and one end of connecting rod I 13 rotate and connect
