As shown in fig. 1 to 6, the child product of the present invention has an unfolded state and a folded state, and includes a first lever 1, a second lever 2, and a third lever 3, two members of the first lever 1, the second lever 2, and the third lever 3 are rotatably connected, and the third member is rotatably connected with any one member of the two members.
When the child product is in a folded condition, the first, second and third bars 1,2 and 3 are brought together. The children's articles for use still include drive assembly, when first pole 1 rotates the direction of keeping away from second pole 2 and expands, accessible drive assembly orders about third pole 3 also to the direction rotation of keeping away from second pole 2, like this, when realizing children's articles for use's expansion operation, need not each part of individual operation, only operate a part and can make whole children's articles for use expand, convenient operation.
The drive assembly comprises a first drive member 41 and a second drive member 42, the first drive member 41 and the second drive member 42 being connected or co-operating, the first drive member 41 being arranged on the first lever 1, the second drive member 42 being rotatably arranged on the second lever 2, the second drive member 42 being further capable of co-operating or disengaging with the third lever 3. When the first rod 1 rotates and expands in a direction away from the second rod 2, the first driving piece 41 moves along with the first rod 1, and the second driving piece 42 is driven to rotate relative to the second rod 2 through connection or cooperation of the first driving piece 41 and the second driving piece 42, so that the second driving piece 42 is matched with the third rod 3, and when the first rod 1 is continuously turned over, the second driving piece 42 continuously rotates to enable the third rod 3 to rotate and expand in a direction away from the second rod 2. When the child is in the unfolded state, the second driving member 42 remains engaged with the third rod 3.
In this embodiment, the first driving member 41 is a traction cable, the second driving member 42 is a swing rod, one end of the traction cable is fixedly arranged on the first rod 1, the other end of the traction cable is connected to the swing rod, one end of the swing rod is rotatably connected with the second rod 2 through the first rotating shaft 5, a matching portion 42a matched with the third rod 3 is arranged on the other end of the swing rod, when the child product is in a folded state, the matching portion 42a is separated from the third rod 3, and when the child product is unfolded, the matching portion 42a is propped against the third rod 3, and the traction cable is tensioned.
Specifically, on the swing rod, the connection part of the traction cable and the swing rod is located between the first rotating shaft 5 and the matching part 42 a. Thus, when the first lever is rotated and unfolded, the swing link can be pulled by the traction cable, so that the engaging portion 42a on the swing link is rotated in a direction approaching the third lever.
The children article further comprises a fourth rod 6, the fourth rod 6 is rotationally connected with any one of the three parts of the first rod 1, the second rod 2 and the third rod 3, and one specific arrangement mode is that the four parts of the first rod 1, the second rod 2, the third rod 3 and the fourth rod 6 are rotationally connected through the same shaft of a second rotating shaft 7, and the first rotating shaft 5 and the second rotating shaft 7 are arranged in parallel. In the present embodiment, the fourth lever 6, the first lever 1, the second lever 2, and the third lever 3 are sequentially arranged in the circumferential direction of rotation.
A first rotation limiting structure is provided between the first rod 1 and the second rod 2, a second rotation limiting structure is provided between the fourth rod 6 and the first rod 1, the first rotation limiting structure may define a relative rotation angle between the first rod 1 and the second rod 2, and the second rotation limiting structure may define a relative rotation angle between the fourth rod 6 and the first rod 1. In this embodiment, the first rotation limit structure and the second rotation limit structure are unidirectional limit structures, when the child product is unfolded, after the fourth rod 6 is reversely rotated to the angle limited by the second rotation limit structure, the fourth rod 6 is continuously rotated to drive the first rod 1 to reversely rotate and unfold, so that the unfolding operation of the child product is quite convenient.
The child product of the present invention may be a stroller including a stroller frame including a front bracket for mounting a front wheel assembly 81, a rear bracket for mounting a rear wheel assembly 82, a push rod, and a seat bar. In this embodiment, the first rod 1 is a seat rod, the second rod 2 is a front bracket, the third rod 3 is a rear bracket, the fourth rod 6 is a push rod, and the upper part of the front bracket, the upper part of the rear bracket, the lower part of the push rod and the rear four parts of the seat rod are rotatably connected through the same shaft of the second rotating shaft 7.
When the stroller is in the unfolded state, the matching part 42a on the swing rod is propped against the rear bracket, and the traction rope is in a tensioning state, as shown in fig. 1 and 2.
When the stroller is folded from the unfolded state, after the locking mechanism arranged between the upper part of the front support, the upper part of the rear support, the lower part of the push rod and the rear part of the seat rod is unlocked, the push rod is rotated forwards and downwards to be close to the front support, the seat rod is rotated downwards under the action of self gravity to be close to the front support, when the seat rod is rotated, the traction rope is gradually loosened, the swing rod is rotated downwards around the first rotating shaft 5 under the action of self gravity, so that the traction lock is gradually wound on the swing rod, the matching part 42a on the swing rod is gradually separated from the rear support until the matching part 42a on the swing rod is separated from the rear support, the front support and the rear support can be rotated relatively to be close to each other until the push rod, the seat rod, the front support and the rear support are tightly close to each other, and the swing rod is accommodated between the front support and the rear support, as shown in fig. 3 and 4.
When the baby carriage is unfolded from the folded state, the push rod is upwards rotated to be far away from the front support, when the push rod is rotated to the limiting angle of the second rotation limiting structure and then is continuously rotated, the seat rod can be driven to synchronously rotate to be far away from the front support, when the seat rod rotates in the direction far away from the front support, the traction rope gradually pulls the swing rod to upwards rotate until the matching part 42a is propped against the rear support again, at the moment, the continuous rotation of the swing rod can drive the rear support to rotate in the direction far away from the front support, as shown in fig. 5 and 6, until the push rod drives the seat rod to rotate to the limiting angle of the first rotation limiting structure, the rear support just rotates to be in place in the direction far away from the front support, the traction rope is in a tensioning state again, and the baby carriage is in the unfolded state.
