Because the bending driven gear 24 cannot rotate under the limiting action of the first clamping groove 211 of the bending driven gear and the second clamping groove 221 of the bending driven gear, when the switch mechanism on the upper handle group 15 is pressed, the switch mechanism drives the bending driving gear 23 through the bending pull rope 26, the first driving teeth 241 of the bending driven gear 24 slide out of the first driving teeth clamping groove 231 of the bending driving gear 23 in the rotation process of the bending driving gear 23, and the bending driving gear 23 pushes the bending driven gear 24, so that the bending driven gear 24 completely enters the first clamping groove 211 of the bending driven gear of the bending lower pivoting part 21, and the upper handle group 15 can rotate relative to the lower handle group 14.
After the switch mechanism is released, after the bending driving gear 23 rotates under the action of the rotating force of the second elastic element 27, the bending driving gear 23 resets to the position before rotation, when the first clamping groove of the bending driven gear and the second clamping groove 221 of the bending driven gear axially coincide, the bending driven gear 24 axially moves towards the second clamping groove 231 of the bending driven gear under the action of the elastic force of the first elastic element 25, the first driving gear 241 slides into the first driving gear clamping groove 231, and the bending driven gear 24 is clamped between the first clamping groove 211 of the bending driven gear and the second clamping groove wheel 221 of the bending driven gear, namely, the upper handle group 15 and the lower handle group 14 are locked.
As shown in fig. 4 and 5, the lower folding locking mechanism includes a lower folding driving gear 34 disposed between the rear foot pivot 32 and the lower handle pivot 33, a lower folding driven gear 35 disposed between the rear foot pivot 32 and the lower folding driving gear 34, a third elastic member 36 disposed between the rear foot pivot 32 and the lower folding driven gear 35, a fourth elastic member 37 disposed between the lower handle pivot 33 and the lower folding driving gear 34, and a vehicle-collecting wire 39 having both ends respectively connected to the lower folding driving gear 34 and the vehicle-collecting slider 38. The rear foot pivoting part 32 and the lower handle pivoting part 33 are respectively provided with a first clamping groove 321 of a lower folding driven gear and a second clamping groove 331 of the lower folding driven gear, which limit the rotation of the lower folding driven gear 35, the side surface of the lower folding driven gear 35 facing the lower handle pivoting part 33 is provided with a second driving tooth 351, and the side surface of the lower folding driving gear 34 facing the rear foot pivoting part 32 is provided with a second driving tooth clamping groove 341 for inserting the second driving tooth 351.
Because the lower folding driven gear 35 cannot rotate under the limiting action of the first clamping groove 321 of the lower folding driven gear and the second clamping groove 331 of the lower folding driven gear, when the vehicle collecting sliding block 38 slides through the vehicle collecting stay 39 to drive the lower folding driving gear 34, the second driving teeth 351 of the lower folding driven gear 35 slide out of the second driving tooth clamping grooves 341 of the lower folding driving gear 34 in the rotating process of the lower folding driving gear 34, and the lower folding driving gear 34 pushes the lower folding driven gear 35, so that the lower folding driven gear 35 completely enters the first clamping groove 321 of the lower folding driven gear, and the lower handle set 14 can rotate relative to the rear foot set 12.
After the vehicle retracting slide block 38 stops sliding, the lower folding driving gear 34 will reset to the position before rotation under the action of the rotation force of the fourth elastic element 37, when the lower folding driven gear first clamping groove 321 and the lower folding driven gear second clamping groove 331 axially overlap, the lower folding driven gear 35 is axially moved by the third elastic element 36 toward the lower folding driven gear second clamping groove 331, and finally the lower folding driven gear 35 is clamped between the lower folding driven gear first clamping groove 321 and the lower folding driven gear second clamping groove 331, namely, the locking of the lower handle group 14 and the rear foot group 12 is realized.
As shown in fig. 8, the upper handle group 15 is provided with a vehicle collecting buckle 151, and the rear leg group 12 is provided with a vehicle collecting hook 121 matched with the vehicle collecting buckle 151. By matching the vehicle collecting buckle 151 with the vehicle collecting hook 121, the child car in a folded state is prevented from being unfolded by mistake, so that the child car is more convenient to carry.
As shown in fig. 1, 6, 7, 8, 9, 10 and 11, the working principle of the folding baby carriage is as follows:
When the baby carrier needs to be folded, the switch mechanism on the upper handle group 15 is pressed, the switch mechanism drags the bending driving gear 23 through the bending pull rope 26, the first driving gear 241 of the bending driven gear 24 slides out of the first driving gear clamping groove 231 of the bending driving gear 23 in the rotation process of the bending driving gear 23, the bending driving gear 23 pushes the bending driven gear 24, the bending driven gear 24 completely enters the first clamping groove 211 of the bending driven gear of the bending lower pivoting part 21, the upper handle group 15 can rotate relative to the rear handle group 14, and the upper handle group 15 is rotated forwards to a position relatively parallel to the lower handle group 14.
