Based on this, the number of the first lock holes 22 is two, and the two first lock holes 22 are provided at intervals along the circumferential direction in which the first link 2 rotates. When the child product is in the unfolded state, the first locking pin 611 is inserted into a first locking hole 22 to lock the positions of the first link 2 and the seat 1. When the child product is in the folded state, the first locking pin 611 is inserted into the other first locking hole 22, locking the positions of the first link 2 and the seat 1.
The second locking mechanism includes a second locking piece 71 slidably provided on the base body 1 and a second locking hole 32 provided on the second link 3, the second locking piece 71 having a second locking pin 711.

The second locking mechanism further comprises a second elastic member 72, wherein the elastic force of the second elastic member 72 is used for driving the second locking member 71 to automatically slide in the direction of enabling the second lock pin 711 to be inserted into the second lock hole 32, i.e. the elastic force of the second elastic member 72 is used for driving the second locking mechanism to automatically reset from the unlocking state to the locking state. In this embodiment, the second elastic member 72 is a spring, and both ends of the spring are respectively disposed on the second locking member 71 and the seat body 1.
In this embodiment, when the child is in the folded state, the second locking mechanism is in the unlocked state, but the second link 3 cannot rotate relative to the base 1 due to the first locking mechanism being in the locked state.
The unlocking mechanism is used for driving the first locking mechanism and the second locking mechanism to unlock from the locking state. The unlocking mechanism comprises a first unlocking piece 81, the first unlocking piece 81 can be arranged on the seat body 1 in a sliding mode, the first unlocking piece 81 is matched with the first locking piece 61 and the second locking piece 71 respectively, and accordingly when the first unlocking piece 81 slides relative to the seat body 1, the first locking piece 61 and the second locking piece 71 can be driven to slide relative to the seat body 1, and the first locking mechanism and the second locking mechanism can be unlocked.
Specifically, as shown in fig. 3, the first unlocking member 81 is provided with a second inclined plane 811 and a third inclined plane 812, the first locking member 61 is provided with a fourth inclined plane 612 adapted to the second inclined plane 811, the second locking member 71 is provided with a fifth inclined plane 712 adapted to the third inclined plane 812, the second inclined plane 811 is in abutting fit with the fourth inclined plane 612, and the third inclined plane 812 is in abutting fit with the fifth inclined plane 712. Thus, when the first unlocking member 81 slides in the left-right direction, the first locking member 61 and the second locking member 71 are urged to slide in the front-rear direction, so as to be respectively disengaged from the first locking hole 22 and the second locking hole 32.
The first unlocking member 81 has an initial position. When the child supplies are in the unfolded state and drive the first unlocking piece 81 to slide a first distance from the initial position relative to the base 1, the first locking mechanism is unlocked, and at the moment, the first unlocking piece 81 is in the first unlocking position. When the child supplies are in the unfolded state and drive the first unlocking piece 81 to slide a second distance from the initial position relative to the seat body 1, the second locking mechanism is unlocked, and at the moment, the first unlocking piece 81 is in the second unlocking position. The first distance is smaller than the second distance, that is, when the first locking mechanism and the second locking mechanism are simultaneously in the locked state and unlocked by sliding the first unlocking member 81, the first locking mechanism and the second locking mechanism are sequentially unlocked.
The unlocking mechanism further comprises a second unlocking piece 82, the second unlocking piece 82 can be arranged on the seat body 1 in a sliding mode, the second unlocking piece 82 is matched with the first unlocking piece 81 through an inclined plane, and accordingly when the second unlocking piece 82 slides in the up-down direction, the first unlocking piece 81 can be driven to slide in the left-right direction. In this embodiment, the housing 1 has a space therein, and the first locking member 61, the second locking member 71 and the first unlocking member 81 are disposed in the space of the housing 1, which makes the appearance of the child product neat and beautiful. The second unlocking piece 82 is partially exposed outside the base body 1, and the naked part of the second unlocking piece is pressed by a human hand.
The unlocking mechanism further comprises a third elastic piece 83, and the elastic force of the third elastic piece 83 is used for driving the first unlocking piece 81 to automatically slide towards the initial position direction, so that the first unlocking piece 81 is automatically reset to the initial position. In this embodiment, the third elastic member 83 is a spring, and two ends of the spring are respectively disposed on the first unlocking member 81 and the seat body 1.
The locking mechanism further comprises a limiting member 9, wherein the limiting member 9 is configured to limit the sliding movement of the first unlocking member 81, and is capable of limiting the first unlocking member 81 to the first unlocking position. The stopper 9 is slidably disposed in the accommodation space of the seat body 1.
When the child product is in the unfolded state, the limiting piece 9 is far away from the sliding path of the first unlocking piece 81, so that the first unlocking piece 81 can slide a second distance relative to the base 1, and the first locking mechanism and the second locking mechanism are unlocked sequentially. When the child product is in the folded state, the limiting member 9 is blocked on the sliding path of the first unlocking member 81, and at this time, the first unlocking member 81 can only slide a first distance relative to the base 1.
The limiting piece 9 is matched with the first connecting rod 2, and when the first connecting rod 2 rotates relative to the seat body 1 to fold the child product, the limiting piece 9 can be driven to slide in the direction of blocking the sliding path of the first unlocking piece 81.
Specifically, the first link 2 is provided with a recess 23, and the stopper 9 is provided with a first inclined surface 91 that mates with the recess 23. When the child product is in the unfolded state, the limiting piece 9 is partially located in the concave portion 23, and the side face of the concave portion 23 abuts against the first inclined face 91, so that when the first connecting rod 2 rotates relative to the base 1 to fold the child product, the limiting piece 9 can slide in the direction of blocking the sliding path of the first unlocking piece 81.
The locking mechanism works as follows:
When the child product is in the unfolded state for use, the first locking mechanism and the second locking mechanism are both in the locked state, so that the first connecting rod 2 and the second connecting rod 3 are locked in the unfolded position, at this time, the first unlocking member 81 and the second unlocking member 82 are both in the initial positions, and the limiting member 9 leaves the sliding path of the first unlocking member 81, as shown in fig. 4 and 5.
When the child product is folded from the unfolded state, the second unlocking piece 82 is pressed to enable the second unlocking piece 82 to slide upwards relative to the base 1, so that the first unlocking piece 81 slides leftwards relative to the base 1, and when the first unlocking piece 81 slides leftwards for a first distance, the first unlocking piece 81 slides to a first unlocking position, and the first locking mechanism is unlocked. Continued pressing of the second unlocking member 82 causes the second unlocking member 82 to slide upward relative to the base 1, and the first unlocking member 81 continues to slide leftward until the first unlocking member 81 slides a second distance from the initial position, at which time the first unlocking member 81 slides to the second unlocking position, and the second locking mechanism is unlocked, as shown in fig. 6 and 7.
The first connecting rod 2 rotates relative to the seat body 1, so that the children products are folded, the first connecting rod 2 rotates relative to the seat body 1, the second connecting rod 3 is driven to synchronously rotate relative to the seat body 1 until the first connecting rod 2 and the second connecting rod 3 rotate to folding positions relative to the seat body 1. When the second unlocking member 82 is released, the first unlocking member 81 is automatically restored to the initial position by the elastic force of the third elastic member 83. The first locking member 61 makes the first locking pin 611 inserted into the other first locking hole 22 under the elastic force of the first elastic member 62, so that the first locking mechanism is in a locked state. At this time, the second lock hole 32 is not provided at a position corresponding to the second lock pin 711 by the second link 3, so that the second lock mechanism is still in the unlocked state. When the first connecting rod 2 rotates relative to the base 1 to fold the child product, the limiting member 9 is driven to slide backward, so as to block the sliding path of the first unlocking member 81, as shown in fig. 8 and 9, and this state is the folded state of the child product.
When the child product is unfolded from the folded state, the second unlocking member 82 is pressed to enable the second unlocking member 82 to slide upwards relative to the base 1, so that the first unlocking member 81 slides leftwards relative to the base 1, when the first unlocking member 81 slides leftwards for a first distance, the first unlocking member 81 slides to a first unlocking position, and the first locking mechanism is unlocked, as shown in fig. 10 and 11. At this time, due to the blocking of the stopper 9, even if the second unlocking piece 82 is continuously pressed, the second unlocking piece 82 and the first unlocking piece 81 cannot continuously slide in the current direction.
The first connecting rod 2 is rotated relative to the base 1 to expand the child product, and when the first connecting rod 2 rotates relative to the base 1, the second connecting rod 3 is driven to synchronously rotate relative to the base 1, the second unlocking piece 82 is always pressed in the process, the first locking mechanism keeps the unlocking state, and when the first connecting rod 2 and the second connecting rod 3 rotate to the expanded positions relative to the base 1, the second locking piece 71 enables the second lock pin 711 to be inserted into the second lock hole 32 for a certain distance under the action of the elastic force of the second elastic piece 72, so that the second locking mechanism is in the locking state, as shown in fig. 12 and 13.
At this time, since the second locking mechanism is in the locked state, the second link 3 cannot rotate relative to the base 1, and the first gear 21 and the second gear 31 are always in the meshed state, so that the first link 2 cannot rotate relative to the base 1, that is, both the first link 2 and the second link 3 are in the extended position and cannot rotate toward the folded position. When the second unlocking member 82 is released, the first unlocking member 81 is automatically restored to the initial position by the elastic force of the third elastic member 83, the first locking member 61 is inserted into the first locking hole 22 by the elastic force of the first elastic member 62, and the second locking member 71 is inserted into the second locking hole 32 by the distance of the second locking pin 711 by the elastic force of the second elastic member 72 is increased until both the first locking mechanism and the second locking mechanism are restored to the initial locking state, as shown in fig. 4 and 5.
