The utility model discloses a working process and principle:
the vehicle lifting process:
before the device prepares to lift wheels, the roller 16 is manually pushed towards the side direction of the underframe 6, the roller 16 moves backwards to drive the rotating connecting rod 7 to rotate, the included angle of the self-locking lower connecting rod group 13 is gradually reduced from 180 degrees, the long connecting rod 8 rotates backwards around the lower hinged support 22, the pushing connecting rod 14 moves to enable the included angle of the self-locking swinging connecting rod group 9 to be gradually reduced from 180 degrees, the pedal 11 rotates from bottom to top, and when the whole seven-connecting-rod lifting mechanism is folded and contracted to the minimum position, the long connecting rod 8 is in a vertical state, and the preparation work before lifting is completed.
The device is placed under the wheel from the side direction of the wheel by means of the opening of the frame of the underframe 6, so that the wheel is aligned with the roller 16 and the connecting shaft 3 of the front holding clamp structure. When the pedal 11 is stepped on by a foot, the pedal 11 rotates downwards, the optical axis 18 on the pedal 11 rotates upwards around the large hinged support 10, the rear connecting rod 17 of the self-locking swinging connecting rod group 9 in contact with the optical axis 18 rotates downwards around the upper hinged support 12 on the upper part of the rear frame 63 and expands, the included angle of the self-locking swinging connecting rod group 9 is increased, the connecting rod 14 is pushed to move and the self-locking lower connecting rod group 13 is expanded, the included angle of the self-locking lower connecting rod group 13 is increased, meanwhile, the long connecting rod 8 is driven to rotate forwards around the lower hinged support 22, and the rotating connecting rod 7 moves to drive the roller 16. The pedal 11 is continuously stepped by the foot, so that the roller 16 on the inner side of the lower part of the rotating rod 7 contacts and extrudes the wheel to push the wheel to move towards the front clasping structure, the wheel firstly contacts the connecting shaft 3 on the lower part of the front clasping structure, and the roller 16 continuously extrudes the wheel to push the wheel to move to a gap formed between the upper connecting shaft 3 and the lower connecting shaft 3 of the front clasping structure.
As shown in fig. 4, at this time, the included angle between the long link 8 of the seven-link lifting mechanism and the underframe 6 is the largest, the self-locking lower link group 13 and the self-locking swinging link group 9 are unfolded into a straight line, the included angle between the link groups is 180 degrees, and the self-locking lower link group 13, the rotating link 7 and the long link 8 form a stable triangle; the self-locking swing connecting rod group 9, the long connecting rod 8, the upper hinged support 12 and the lower hinged support 22 form another stable triangle, and a double self-locking state is realized under the action of gravity of the wheel squeezing roller 16.
The parking process:
the footboard 11 is up played to the foot, footboard 11 rotates around big hinged-support 10 through-hole, optical axis 18 up rotates, in the rotation process, auto-lock swing linkage 9 reduces by rectilinear state gradually, drive and the push link 14 upward movement of linkage 13 middle part junction under the auto-lock, linkage 13 reduces by rectilinear state gradually under the auto-lock, long connecting rod 8 rotates backward round lower hinged-support 22, drive and rotate connecting rod 7 rearward movement, drive 16 backward movements of cylinder, the folding shrink of whole seven connecting rod lifting mechanism. Because the front holding clamp structure is in a step shape, under the action of the gravity of the wheel, the wheel leaves a gap formed by the upper connecting shaft 3 and the lower connecting shaft 3 of the front holding clamp structure until the seven-connecting-rod lifting mechanism is contracted to the minimum position, the long connecting rod 8 is in a vertical state, and the wheel is contacted with the ground, so that the parking process is completed.
