Sequence of mechanical actions of the whole device:

when the present invention is in the initial state, the first spring 79 is in a relaxed state, the second spring 33 is in a relaxed state, the third spring 76 is in a relaxed state, and the fourth spring 53 is in a relaxed state;

when the apparatus of the present invention is operated, a baby is laid down in the baby cavity 30 while pressing the left and right carrier plates 31 and 67 downward, compressing the second spring 33, the right bearing plate 67 moves downwards to drive the rack 69 to move downwards, the rack is meshed with the fifth gear 71 to drive the fifth gear 71 to rotate, the pull rope 72 is tightened, the sun visor 41 is pulled to slide upwards, at the same time, the third slider 75 slides upwards to stretch the third spring 76, and when the sun visor 41 moves out of the fourth sliding chamber 40, it is turned to the upper side of the baby chamber 30 due to gravity, so as to shade the baby in the baby chamber 30, meanwhile, the first relay switch 65 and the second relay switch 66 on both sides are engaged, so that the magnet 80 is electrified and magnetized to attract the electromagnet 81 to move downwards, thereby moving the first slider 78 downward, stretching the first spring 79, and simultaneously moving the third gear 83 downward to the position of mutual engagement with the gear 17;

if the equipment needs to be moved, the motor 24 is started to drive the driving shaft 23 to rotate, the fourth gear 21 is driven to rotate, the first gear 20 is driven to rotate through meshing, the coaxial travelling wheel 22 is driven to rotate, and parents can easily push the whole equipment to travel by only controlling the direction through the handle 38, so that the physical strength is saved;

if the front side and the rear side of the cradle 12 are collided in the moving process of the device, the balancing weight 45 is driven to move back and forth, the fourth spring 53 is compressed, the fourth connecting rod 54 is driven to move, the second clamping block 47 is driven to move, the fifth sliding block 48 is driven to slide, the fifth connecting rod 49 is driven to slide, and the air bag 52 extends into the baby cavity 30 to protect children.

When a baby needs to sleep quietly, the first block 57 is pulled to the left side to release the clamping of the supporting block 59, the supporting block 59 moves upwards to drive the first link 25 to move upwards, the fourth gear 21 is disengaged from the first gear 20 and then is engaged with the third gear 83, the motor 24 drives the driving shaft 23 to rotate, the third gear 83 is engaged to rotate, the third gear 17 is engaged again to rotate, the coaxial first belt pulley 18 is driven to rotate, the second belt pulley 27 is driven to rotate through the transmission of the baby cavity 30, the coaxial second chain wheel 28 is driven to rotate, the chain 29 is driven to rotate, the fourth slider 64 moves along the chain 29, the fourth slider 64 slides in the sliding rail 63 to drive the fixing rod 62 to slide left and right, the roller 61 presses the curved bar 39 to swing, so as to drive the cradle 12 to swing, simulate the pregnant condition and enable the baby to fall asleep steadily;

at this time, if the baby in the baby cavity 30 sits up, the right support plate 67 loses bearing, driving the rack 69 to move upwards, and the third slider 75 rebounds under the action of the third spring 76 to drive the sun visor 41 to be accommodated in the sun visor 40, so as to prevent the baby from hitting the sun visor 41 and being injured when the baby starts up, and the first relay switch 65 on the right side after the right support plate 67 slides upwards is no longer in contact with the second relay switch 66 on the right side, so that the second link 84 is demagnetized, the first slider 78 rebounds under the action of the first spring 79, the third gear 83 is no longer meshed with the third gear 21, the swing device 101 loses power and does not swing any more, so as to prevent the baby sitting up from shaking and being injured.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
