[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art.

[0029] The child product provided in this embodiment is specifically a child stroller. In some other embodiments, the child product may also be a foldable child product such as a dining chair. Figures 1 to 7 As shown, the children's product comprises a first rod 1 and a second rod 2, which are rotatably connected via a connecting shaft 11. Specifically in this embodiment, the first rod 1 is a front wheel bracket, and the second rod 2 is a rear wheel bracket. A front wheel 3 is mounted on the lower end of the first rod 1, and a rear wheel 4 is mounted on the lower end of the second rod 2. The upper part of the first rod 1 and the upper end of the second rod 2 are pivotally connected via the connecting shaft 11.

[0030] Combination Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, at least the first rod 1 or the second rod 2 is provided with a long slot 21 that matches the connecting shaft 11, and the connecting shaft 11 can be inserted into the long slot 21 slidably along the extension direction of the long slot 21. The first rod 1 has a first abutting portion, and the second rod 2 has a second abutting portion that can be in close contact with the first abutting portion. The children's product has an unfolded state, a first folded state, and a second folded state. Figures 1 to 3 As shown, when the children's product is in the unfolded state, the first rod 1 and the second rod 2 are relatively unfolded, the connecting shaft 11 is located at the first position in the long slot 21, and the first abutting portion and the second abutting portion are in close contact with each other to prevent the connecting shaft 11 from sliding along the long slot 21. Figure 4 and Figure 5As shown, when the children's product is in the first folded state, the first rod 1 and the second rod 2 are close to each other, the connecting shaft 11 is located at the first position in the long groove 21, and the first abutting portion and the second abutting portion are separated from each other. Figure 6 and Figure 7 As shown, when the child product is in the secondary folded state, the first rod 1 and the second rod 2 are further brought together, and the connecting shaft 11 is located at the second position in the long groove 21. In addition, when the child product is in the primary folded state, the first rod 1 and the second rod 2 are brought together to form a first angle; when the child product is in the secondary folded state, a second angle is formed between the first rod 1 and the second rod 2; and the second angle is smaller than the first angle.

[0031] Specifically in this embodiment, the connecting shaft 11 is arranged on the first rod 1, and the long slot 21 is opened on the second rod 2, and the long slot 21 extends along the length direction of the second rod 2. The first rod 1 includes a rod-shaped body 1a and a joint 1b connected to the upper end of the rod-shaped body 1a, and the second rod 2 includes a rod-shaped body 2a and a joint 2b connected to the upper end of the rod-shaped body 2a. Here, "the length direction of the second rod" specifically refers to the length direction of the rod-shaped body 2a of the second rod 2, that is, the extension direction of the rod-shaped body 2a, such as Figure 2 The direction indicated by the arrow L in the middle. The connecting shaft 11 is arranged on the joint 2b, and the long slot 21 is opened on the joint 2b. The long slot 21 has a first end and a second end opposite to each other, and the distance between the second end of the long slot 21 and the end of the rod-shaped body 2a is smaller than the distance between the first end and the end of the rod-shaped body 2a. The above-mentioned first position is specifically at the first end of the long slot, and the above-mentioned second position is specifically at the second end of the long slot. Therefore, when the children's product is in the unfolded state and the once folded state, the connecting shaft 11 is located at the first end of the long slot 21; when the children's product is in the second folded state, the connecting shaft 11 is located at the second end of the long slot 21.

[0032] The first contact portion is a first contact surface 12 facing the rod-shaped body 2a, which is formed on the joint 1b of the first rod 1. The second contact portion is a second contact surface 22 formed on the joint 2b of the second rod 2, and the second contact surface 22 can be arranged opposite to the first contact surface 12 and contact and cooperate with it, and can prevent the connecting shaft 11 from sliding toward the second end of the long groove 21 when in the unfolded state. In this embodiment, the first contact surface 12 and the second contact surface 22 are both planes, and the second contact surface 22 is located at the top of the second rod 2, specifically the top of the joint 2b.

[0033] The second rod 2 also has an arcuate surface 23 connected to or adjacent to the second contact surface 22, and the arcuate surface 23 can also be replaced by an inclined surface. By providing the arcuate surface 23 or the inclined surface, the relative rotation of the first rod 1 and the second rod 2 is prevented from being hindered when folding. The first rod 1 also has an arcuate surface 13 connected to or adjacent to the first contact surface 12, and the arcuate surface 13 can be replaced by an inclined surface. When the children's product is in the unfolded state and the first folded state, the arcuate surface 13 on the first rod 1 and the arcuate surface 23 on the second rod 2 are opposite and have a gap; when the children's product is in the second folded state, the arcuate surface 23 on the second rod 2 is against the first contact surface 12 on the first rod 1, and the two are in contact and matched.

[0034] Combination Figure 1 , Figure 4 and Figure 6 As shown, the children's product further includes a push rod 5 and a connecting rod 6, the push rod 5 is rotatably connected to the first rod 1, the connecting rod 6 is rotatably connected to the push rod 5 and the second rod 2 respectively, and the rotational connection between the first rod 1 and the push rod 5 is located between the rotational connection between the first rod 1 and the second rod 2 and the rotational connection between the push rod 5 and the connecting rod 6 (as shown in FIG. Figure 1 The angle formed between the first rod 1 and the push rod 5 when the child product is in the primary folding state is greater than the angle formed between the first rod 1 and the push rod 5 when the child product is in the secondary folding state.

[0035] The use process of the children's products is as follows:

[0036] like Figures 1 to 3 As shown, when the children's product is in the unfolded state, the first rod 1 and the second rod 2 are relatively unfolded, the connecting shaft 11 is located at the first end of the long slot 21, and the second contact surface 22 on the second rod 2 and the first contact surface 12 on the first rod 1 are opposite and in close contact with each other, and the first contact surface 12 provides a blocking effect, that is, the first rod 1 and the second rod 2 are completely constrained by the first contact surface 12 and the second contact surface 22, and at this time, the connecting shaft 11 will not slide toward the second end of the long slot 21, so that the first rod 1 and the second rod 2 are stably unfolded;

[0037] When folding, the first rod 1 and the second rod 2 are first rotated around the connecting shaft 11 so as to be close to each other. Figure 4 and Figure 5 The first folding state shown in the figure; at this time, the connecting shaft 11 is still located at the first end of the long groove 21, the first contact surface 12 and the second contact surface 22 are separated from each other, and there is a distance between the arc surface 13 and the arc surface 23, that is, the first rod 1 and the second rod 2 are in a semi-constrained state, and the connecting shaft 11 can slide along the long groove 21 after an external force is applied;

[0038] The external force F1 is continuously applied to the first rod 1 or the external force F2 is continuously applied to the second rod 2 in the direction indicated by the arrow, the second rod 2 continues to move closer to the first rod 1, the connecting shaft 11 slides along the long groove 21 to the second end of the long groove 21, and the children's product is in the state as shown in FIG. Figure 6 and Figure 7 The secondary folding state is shown; at this time, the first rod 1 and the second rod 2 are further brought closer, so that the volume of the children's product after folding is further reduced.

[0039] It should also be noted that when the children's product is in the unfolded state, the first folded state or the second folded state, the bottoms of the wheels are located on the same plane, that is, during the unfolding and folding process, the front wheels 3 and the rear wheels 4 can both touch the ground and achieve self-support.

[0040] The above embodiments are only for illustrating the technical concept and features of the present invention, and are preferred implementation methods. Their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
