The folding and unfolding mechanism is characterized in that: the locking part comprises a sliding block 91 which can longitudinally slide in the rear hinge shell 4, the front hinge shell 3 is provided with a clamping groove 92 which can be clamped with the sliding block 91, and the rear hinge shell 4 is also provided with a boss 93 which can prevent the clamping hook 8 from sliding in the arc-shaped groove 7 when the sliding block 91 is clamped with the clamping groove 92.
The folding and unfolding mechanism is characterized in that: the handle 6 comprises a U-shaped holding rod 61, two ends of the holding rod 61 are respectively provided with a plug-in part 62 which can rotate relative to the holding rod, and the handle seat 5 is provided with a plug-in groove which can be in plug-in fit with the plug-in part 62.
The folding and unfolding mechanism is characterized in that: the front frame 1 is also connected with a connecting seat 10 which can connect the folding and unfolding mechanism to the baby carriage.
Compared with the prior art, the invention has the following advantages:
1. when the front frame, the rear frame and the handle are in the unfolding position, the locking parts can lock and keep the positions of the front frame, the rear frame and the handle, after the locking parts are unlocked, the rear hinge shell rotates relative to the front hinge shell, so that the rear frame is folded, then the handle is pushed, the clamping hook slides in the arc-shaped groove, and the handle seat rotate together to be folded. The whole folding and unfolding mechanism is convenient to operate, small in size after being folded, and convenient to carry, and the folded size of the baby carriage can be ensured after the baby carriage is assembled on the baby carriage.
2. When the locking part locks the front frame, the rear frame and the handle, the sliding block is clamped with the clamping groove to prevent the rear hinge shell from rotating relative to the front hinge shell, and meanwhile, the boss on the rear hinge shell is contacted with the clamping hook on the handle seat, so that the clamping hook is prevented from rotating in the arc-shaped groove, and the handle is prevented from rotating relative to the front hinge shell. When the folding is needed, the sliding block can rotate the rear hinge shell only by withdrawing from the clamping groove on the front hinge shell, once the rear hinge shell rotates, the boss on the rear hinge shell does not resist the clamping hook any more, therefore, the clamping hook can rotate in the arc-shaped groove, the handle can rotate relative to the front hinge shell to fold, the operation is very simple and quick, and the locking component simultaneously locks the rear frame and the handle, so that the folding device is compact in structure and very ingenious in design.
3. The invention has simple structure and convenient operation, and is suitable for popularization and application.

[ detailed description ] of the invention
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1 to 8, a folding and unfolding mechanism comprises a front frame 1 and a rear frame 2 capable of rotating relative to the front frame 1, wherein the front frame 1 is provided with a front hinge shell 3, the rear frame 2 is provided with a rear hinge shell 4 rotationally connected with the front hinge shell 3, the front hinge shell 3 and the rear hinge shell 4 are also connected with a handle seat 5 capable of rotating relative to the front hinge shell 3 and the rear hinge shell 4, the handle seat 5 is detachably connected with a handle 6, the front hinge shell 3 is provided with an arc groove 7, the handle seat 5 is provided with a clamping hook 8 capable of sliding in the arc groove 7 and hooking the side wall of the front hinge shell 3 to connect the handle seat 5 with the front hinge shell 3, and a locking component capable of locking and keeping the front frame 1, the rear frame 2 and the handle 6 in an unfolding state is arranged between the rear hinge shell 4 and the front hinge shell 3. When the front frame 1, the rear frame 2 and the handle 6 are in the unfolding position, the locking parts can lock and keep the positions of the front frame 1, the rear frame 2 and the handle 6, when the locking parts are unlocked, the rear hinge housing 4 rotates relative to the front hinge housing 3, so that the rear frame 2 is folded, then the handle 6 is pushed again, the clamping hooks 8 slide in the arc-shaped grooves 7, and the handle 6 rotates together with the handle seat 5 to be folded. The whole folding and unfolding mechanism is convenient to operate, small in size after being folded, and convenient to carry, and the folded size of the baby carriage can be ensured after the baby carriage is assembled on the baby carriage.
