Detailed Description
As shown in the figure, the four-bar folding type air bag folding mechanism comprises a folding structure and a four-bar power rotary structure,
the folding structure comprises a clamping plate 1, a clamping plate fixing piece 2, a gear I3, a bearing I4, a gear II 5, a rack 6, a gear III 7, a bearing II 8 and a supporting frame 9. The inner wall of the supporting frame 9 is fixedly connected with a middle rod 10 which is transversely arranged; the middle rod 10 is sleeved with a sliding block 16. The folding structure performs a specific folding action of the airbag.
The four-bar power swivel structure comprises: crank 12, connecting rod I13, exhibition pole 14, connecting rod II 15 and support II 17; the four bar power swivel structure not only provides power, but also can make the folding structure do cyclic reciprocating motion along the rack 6 in a section of length due to the special swivel property of the structure.
In the four-bar power rotary structure, a crank 12 is used as a driving bar, one end of the crank 12 is rotationally connected with one end of a connecting rod I13, and the other end of the crank 12 is rotationally connected with a support I11. The motor is placed at the support I11 and the support I11 is connected to the motor. The other end of the connecting rod I13 is rotationally connected with the connecting rod II 15, the display rod 14 is rotationally connected with one end of the bearing II 8, the middle part of the bearing II 8 is provided with the supporting frame 9, the middle part of the supporting frame 9 is provided with the middle rod 10, and the synchronous and coordinated action of the four-rod power rotary structure can be ensured when the four-rod power rotary structure moves linearly. The other side of the bearing II 8 is provided with a gear II 5 and a gear III 7 in sequence, and the upper part of the gear II 5 is contacted with and meshed with the gear I3. The support II 17 is fixedly arranged on the working platform, and the support II 17 and the support I11 are positioned on the same straight line.
